- a user 10 is illustrated firing projectiles or paintballs at two respective targets 12 a , 12 b using a compressed gas projectile accelerator or paintball marker 14 .
- User 10 is shooting at target 12 a with a marker 14 that is set or configured to expel paintballs at target 12 a at an upper velocity setting, which in this form comprises the maximum allowable velocity setting of 300 FPS.
- an upper velocity setting which in this form comprises the maximum allowable velocity setting of 300 FPS.
- the paintball tends to travel along somewhat of an arced path after traveling a predetermined distance due to the force of gravity on the paintball.
- user 10 is somewhat closer to target 12 b (e.g. ⁇ 80 feet) who is hiding behind an obstacle 16 , which is illustrated as a barrel for representative purposes only. If user 10 fires a paintball at target 12 b with marker 14 set at the upper velocity setting, it would be extremely difficult, if not impossible, for user 10 to hit target 12 b due to the fact that obstacle 16 is providing cover for target 12 b . This is because the paintball will travel along a relatively straight path toward target 12 b thereby causing the paintball to strike obstacle 16 and not target 12 b .
- paintballs are expelled from the marker 14 along a relatively straight path over short distances, which are the typical distances encountered on the field when shooting at a respective target 12 a , 12 b.
- a representative paintball marker 50 is illustrated that includes an on the fly velocity adjustment mechanism 52 .
- Velocity adjustment mechanism 52 is operably configured to allow user 10 to manually and selectively adjust the velocity at which paintballs are expelled from a barrel 54 of the marker 50 .
- Marker 50 is configured to expel projectiles from marker 50 at a range of velocities ranging from an upper velocity setting to a lower velocity setting.
- the upper velocity setting corresponds to the maximum velocity at which a paintball is allowed to be expelled from barrel 54 , which may be 300 FPS for example.
- the lower velocity setting corresponds to the lowest possible velocity setting at which marker 50 is capable of expelling a paintball from barrel 54 .
- different user preferred upper and lower velocity settings may be utilized in various other forms of the present invention.
- marker 50 includes a housing or frame body 56 , a grip frame rail 58 , a grip or grip frame 60 , a trigger mechanism 62 , and a feed tube 64 for a projectile or paintball hopper 63 (See FIG. 1 ).
- body 56 is connected with grip frame rail 58 or alternatively grip frame rail 58 may be an integral part of body 56 .
- Barrel 54 is connected with one respective end of body 56 and, in this illustrative form, velocity adjustment mechanism 52 is connected with the opposite end of body 56 .
- Feed tube 64 which a paintball hopper (not shown) is removably connected with and feeds paintballs to marker 50 , is also connected with or formed as part of body 56 .
- Trigger mechanism 62 is movably connected with grip frame rail 58 and is configured to, with each trigger pull, expel a paintball from barrel 54 (at least in semi-automatic firing mode). In automatic firing mode, a plurality of paintballs are expelled from barrel 54 .
- an electro-pneumatic marker 50 in another representative form, includes an electronic circuit board 66 and a power source 68 . Although illustrated as being housed in grip frame 60 , it should be appreciated that circuit board 66 and power source 68 may be housed in other locations of marker 50 .
- Power source 68 is connected with circuit board 66 and provides power to circuit board 66 .
- Electro-pneumatic marker 50 includes a trigger sensor 70 that is connected with circuit board 66 .
- a velocity or speed sensor 72 and a solenoid valve 74 are also connected with circuit board 66 .
- Speed sensor 72 could comprise a laser, an optical eye, a LED speed sensor, or any other suitable type of speed sensor.
- a velocity controller 76 is also connected with circuit board 66 .
- velocity adjustment mechanism 52 includes a main velocity adjustor 80 .
- Main velocity adjustor 80 is configured to adjust a velocity setting of marker 50 .
- main velocity adjustor 80 is configured to adjust marker 50 so that marker 50 cannot expel paintballs above a predetermined upper or maximum velocity setting, which, for illustrative purposes only, is at or below 300 FPS.
- main velocity adjustor 80 comprises an allen head screw configured to adjustably control the upper velocity setting of marker 50 .
- adjustment of main velocity adjustor 80 by tightening or loosening main velocity adjustor 80 , increases or decreases the maximum velocity setting of marker 50 .
- Velocity adjustment mechanism 52 includes an adjustment device or member 82 that is connected with main velocity adjustor 80 .
- adjustment device 82 comprises a lever selector that is secured to main velocity adjustor 80 with a retention member or set screw 84 .
- Adjustment device 82 includes an aperture 85 that fits around an outside diameter of main velocity adjustor 80 .
- lever selector 82 In order to prevent user 10 from being able to turn lever selector 82 clockwise, thereby increasing the velocity at which a projectile may be expelled, lever selector 82 must be restricted. As previously discussed, any velocity above the upper or maximum velocity setting would cause marker 50 to be viewed as a “hot marker” as understood by those skilled in the art.
- dial 86 includes a plurality of apertures 88 that are positioned around a circumference or perimeter of dial 86 .
- a blocking pin 90 is positioned or placed in a respective aperture 88 immediately next to lever 82 to prevent lever selector 82 from being rotated any further in the clockwise direction. As such, this prevents user 10 from being able to adjust the velocity setting of marker 50 above the upper velocity setting. This is an important feature as user 10 would not be allowed to use marker 50 if he/she was capable of adjusting marker 50 to shoot above the maximum allowed velocity setting by simply moving levor selector 82 .
- lever selector 82 As user 10 rotates lever selector 82 counterclockwise, the velocity at which paintballs are expelled from barrel 54 of marker 50 begins to decrease. For example, at the setting illustrated in FIG. 3 b , marker 50 is set to expel paintballs at approximately 215 FPS. The further lever selector 82 is adjusted counterclockwise, the velocity at which paintballs are expelled from marker 50 decreases until, as illustrated in FIG. 3 c , lever selector 82 reaches a lower velocity setting. In FIG. 3 c , the lower velocity setting is controlled by placement of a blocking pin 92 in another user selected aperture 88 of dial 86 .
- lever selector 82 will hit or bump up against pins 90 and 92 , which do not allow lever selector 82 to be adjusted any further beyond the upper and lower velocity settings.
- Selector 82 may also include a detainment mechanism, which is a detent 94 in this example, that is located in alignment with apertures 88 on dial 86 to help temporarily secure the selector 82 in place once a velocity setting is chosen by user 10 .
- Pins 90 , 92 may comprise standard pins, set screws, or any other type of equivalent device that will restrict movement of lever selector 82 beyond the upper and lower velocity settings.
- Apertures 88 may be threaded and in one form, dial 86 is connected to body 56 of marker 50 and in another form, dial 86 is formed as an integral part of body 56 or other components of marker 50 disclosed herein.
- FIG. 4 a a side view of one illustrative form of marker 50 is illustrated showing velocity adjustment mechanism 52 located directly on marker 50 .
- velocity adjustment mechanism 52 is illustrated as being located or positioned at the back or rear of body 56 ; however, those skilled in the art should appreciate that velocity adjustment mechanism may be located at several other positions on marker 50 .
- Marker 50 includes a compressed gas source 100 , which may contain compressed air, CO 2 , nitrogen, or any other type of suitable compressed gas, which is removably connected with a tank adapter 102 of marker 50 .
- the compressed gas stored in source 100 is used to selectively expel projectiles from barrel 54 of marker 50 .
- a gas line 104 connects an output of tank adapter 102 to a pressure regulator 106 .
- Compressed gas from compressed gas source 100 is in communication with pressure regulator 106 .
- Pressure regulator 106 prevents gas pressures from rising above a predetermined threshold level before entering marker 50 , to prevent damage of the internal components of marker 50 .
- Pressure regulator 106 includes an adjustment knob 108 that provides for adjustment of one or more operating parameters of pressure regulator 106 .
- velocity adjustment mechanism 52 is configured as an integral part of pressure regulator 106 . As such, movement of selector 82 on regulator 106 between an upper set point and a lower set point will cause marker 50 to expel projectiles from barrel 54 between a maximum or upper velocity setting and a minimum or lower velocity setting.
- velocity adjustment mechanism 52 has been incorporated as a component of tank adapter 102 . Movement of selector 82 on tank adapter 102 between an upper set point and a lower set point will cause marker 50 to expel projectiles from barrel 54 between an upper velocity setting and a lower velocity setting. All of the features discussed above with reference to FIGS. 3 a - 3 c are hereby incorporated by reference into the representative forms set forth in FIGS. 4 b and 4 c.
- velocity adjustment mechanism 52 is mounted on a side of marker 50 .
- Selector 82 is illustrated as being set at the maximum velocity setting.
- rotation of selector 82 clockwise causes main velocity adjustor 80 to block a gas passage in marker 50 thereby allowing user 10 to incrementally reduce the velocity of paintballs that are expelled from barrel 54 .
- main velocity adjustor 80 causes main velocity adjustor 80 to block a gas passage in marker 50 thereby allowing user 10 to incrementally reduce the velocity of paintballs that are expelled from barrel 54 .
- marker 50 includes a bolt 112 that travels back and forth along a longitudinal axis in a bolt chamber or bore 114 inside body 56 of marker 50 .
- Bolt 112 includes a gas passage 116 through which compressed gas passes in order to expel paintballs from barrel 54 .
- a gas port 118 in bolt 112 reaches a valve passage 120 .
- trigger mechanism 62 releases a hammer 122 that travels forward under the pressure or force provided by a hammer spring 124 .
- hammer 122 strikes a respective end of a valve 126 , thereby actuating valve 126 .
- Actuation of valve 126 causes compressed gas, which is stored in a compressed gas storage chamber 128 on an opposite side of valve 126 , to vent through valve passage 120 into gas passage 116 of bolt 112 through gas port 118 .
- bolt 112 and hammer 122 move together and gas port 118 is positioned on bolt 112 such that gas port 118 is aligned with valve passage 120 when hammer 122 strikes valve 126 .
- a bolt and hammer connecting pin 127 is used to connect bolt 112 with hammer 122 .
- compressed gas is permitted to travel from compressed gas storage chamber 128 to valve passage 120 and then into gas passage 116 of bolt 112 via gas port 118 . This compressed gas is then used to expel a paintball from the barrel 54 .
- valve 126 After compressed gas is expelled from chamber 128 , a spring 129 connected to an end of valve 126 forces valve 126 shut or closed, thereby stopping the flow of compressed gas through valve passage 120 . At the same time compressed gas is passed through passage 120 , compressed gas is also directed to a hammer chamber 131 , which causes hammer 122 and bolt 112 to recoil for another shot.
- an adjustable relief valve 130 is a venting mechanism connected with an exposed end of bolt 112 .
- Adjustable relief valve 130 is used to control or limit the pressure that is supplied from the flow of compressed gas utilized to expel paintballs from barrel 54 .
- compressed gas travels forward to expel a paintball from barrel 54 and backwards towards venting mechanism on end 134 of bolt 112 .
- a predetermined amount of compressed gas will vent through velocity adjustment mechanism 110 .
- Adjustable relief valve 130 includes an adjustment mechanism 136 , a knob or wheel in this illustrative example, that allows user 10 to adjust velocity settings between the maximum or upper velocity setting and the minimum or lower velocity setting.
- marker 50 includes a velocity adjustment mechanism 110 located on body 56 .
- velocity adjustment mechanism 110 is a venting mechanism located at an end 150 of barrel 54 .
- bolt 112 does not travel completely to end 150 of barrel 54 .
- a gap exists between an end 152 of bolt 112 and end 150 of barrel 54 during a firing operation such that a seal is not formed between barrel 54 and bolt 112 .
- Body 56 includes a gas port 154 that is connected with a venting mechanism, which is an adjustable relief valve 156 in this form.
- compressed gas travels through gas passage 116 .
- Velocity adjustment mechanism 110 includes a knob 158 that is used by user 10 to control the amount of compressed gas that is released from adjustable relief valve 156 .
- Adjustable relief valve 156 is thus capable of allowing marker 50 to expel projectiles between a maximum or upper velocity setting and a minimum or lower velocity setting.
- bolt 112 includes a gas passage 116 that includes input port 118 and an output port 160 , in addition to a port 162 used to expel paintballs from barrel 54 .
- Body 56 includes a gas port 164 that aligns with output port or vent 160 of bolt 112 during a firing operation and redirects a predetermined amount of compressed gas to a venting mechanism.
- marker 50 includes a velocity adjustment mechanism 166 , which comprises an adjustable relief valve 168 that acts or functions as the venting mechanism.
- velocity adjustment mechanism 166 is located behind feeder 64 in body 56 .
- Adjustable relief valve 168 includes a knob 170 that is used by user 10 to control the amount of compressed gas that is released from adjustable relief valve 168 . Adjustable relief valve 168 is thus capable of allowing marker 50 to expel projectiles between a maximum velocity setting and a minimum velocity setting.
- a portion of another representative marker 50 is illustrated that includes a velocity adjustment mechanism 180 .
- a hammer spring end cap 182 is connected with an end 184 of body 56 .
- Hammer spring end cap 182 is threadably connected with body 56 or friction fit with body 56 .
- a threaded end 185 of a main velocity adjustor 186 is secured in a threaded aperture 188 of hammer spring end cap 182 .
- Main velocity adjustor 186 has an unthreaded end 190 that extends from threaded end 185 into the body 56 of marker 50 and includes a spring retention collar 192 .
- An end 194 of hammer spring 124 fits around unthreaded end 190 of main velocity adjustor 186 and rests against collar 192 .
- a portion of main velocity adjustor 186 fits within a retention aperture 196 of end cap 182 .
- main velocity adjustor 186 is used to set the maximum or upper velocity setting by adjustment of main velocity adjustor 186 in end cap 182 .
- Main velocity adjustor 186 is used to adjust the tension on hammer spring 124 . The more tension that is applied to hammer spring 124 (i.e.—by screwing main velocity adjustor 186 further into end cap 182 ), the harder hammer 122 strikes valve 126 during a firing operation. The harder hammer 122 strikes valve 126 , the longer valve 126 is activated and a greater volume of compressed gas is released from valve 126 , thereby expelling paintballs from barrel 54 at a higher velocity.
- loosening main velocity adjustor 186 which lessens the tension applied to hammer 122 by spring 124 , causes hammer 122 to strike valve 126 with less force during a firing operation. This causes a quicker activation of valve 126 and a release of a lesser gas volume during a firing operation, thereby expelling paintballs from barrel 54 at a lower velocity.
- this form may include an adjustment device 82 (e.g.—a selector lever).
- main velocity adjustor 186 Once main velocity adjustor 186 has been set to expel projectiles at an upper velocity level or setting, selector 82 may be connected with or adjusted on main velocity adjustor 186 .
- dial 86 is not included in this form, it could be connected with end cap 182 .
- end cap 182 includes apertures 88 .
- pins or set screws 90 and 92 may be positioned in apertures 88 to ensure that selector 82 cannot be adjusted above the upper velocity setting or below the minimum or lower velocity setting. See FIGS. 3 a - 3 c .
- Set screw 84 is used to secure selector 82 to main velocity adjustor 186 .
- marker 50 includes a velocity adjustment mechanism 200 that adjusts the tension applied by spring 129 to valve 126 .
- the velocity adjustment mechanism 200 can be configured additionally on marker 50 with or without the above described main velocity adjustor 186 .
- Velocity adjustor 202 is positioned in a valve spring retention member 204 .
- Retention member 204 is connected with body 56 and is positioned in chamber 128 .
- Velocity adjustor 202 includes a threaded end 206 , a sealing member 208 , an extension member 210 , and a collar 212 . Threaded end 206 is threaded into an internally threaded aperture 214 of retention member 204 and transitions into sealing member 208 .
- Sealing member 208 includes one or more seals 216 that form a fluid tight seal between sealing member 208 and an internal bore 218 of retention member 204 .
- Extension member 210 extends away from sealing member 208 inside internal bore 218 and transitions into collar 212 .
- An end 220 of spring 129 is connected with collar 212 and an opposite end 222 of spring 129 is connected with an end of valve 126 .
- Velocity adjustment mechanism 200 works in conjunction with hammer 122 in this form. Velocity adjustment mechanism 200 is used to adjust the force applied to the end of valve 126 . The more force that is applied to valve 126 , the faster valve 126 shuts after being struck by hammer 122 . As such, as threaded end 206 is tightened into retention member 204 , more force is applied to valve 126 by spring 129 . Likewise, as threaded end 206 is loosened from retention member 204 , less force is applied to valve 126 . The faster valve 126 closes, the less volume of compressed gas is allowed to pass through valve 126 to expel projectiles from barrel 54 of marker 50 .
- marker 50 includes a velocity adjustment mechanism 250 that adjusts the volume of gas and the tension on spring 129 to control the force at which a paintball is expelled from barrel 54 .
- Velocity adjustment mechanism 250 includes a velocity adjustor 252 that is threaded into body 56 of marker 50 .
- velocity adjustor 252 is threaded into chamber 128 of marker 50 .
- Velocity adjustor 252 includes a threaded segment 254 , an extension segment 256 , and a spring receiving segment 258 . Threaded segment 254 is threaded into an internally threaded segment 260 of bore 253 .
- Extension segment 256 extends away from threaded segment 254 a predetermined distance into bore 253 .
- Spring receiving segment 258 includes an aperture 262 that receives a first end 264 of spring 129 .
- a second end 266 of spring 129 is connected with or engages an end 268 of valve 126 .
- At least one seal 278 is positioned between spring receiving segment 258 and bore 253 to provide a fluid tight seal for chamber 128 , which is defined by bore 253 , spring receiving segment 258 and valve 126 .
- chamber 128 comprises a compressed gas storage chamber that is refilled with compressed gas after each shot.
- the compressed gas has a predetermined pressure level, which is controlled by regulator 106 , and a predetermined volume. While the pressure level does not change, velocity adjustment mechanism 250 is configured to change the volume or amount of compressed gas that is stored in chamber 128 . In addition, the tension on spring 129 is also adjusted which, in turn, changes the amount of force applied to end 266 of spring 129 .
- velocity adjustor 252 is configured to allow marker 50 to expel paintballs from barrel 54 at a maximum or upper velocity setting.
- adjustment device or selector 82 allows user 10 to adjust operation of marker 50 between the upper velocity setting and the lower velocity setting. Tightening, or screwing in velocity adjustor 252 , increases the tension on spring 129 , thereby causing valve 126 to close faster when hammer 122 strikes valve 126 , as well as decreases the volume of chamber 128 .
- Loosening velocity adjustor 252 decreases the force placed on valve 126 and increases the volume of chamber 128 (i.e.—thereby allowing more compressed gas into chamber 128 ), which allows paintballs to be expelled from barrel 54 at a higher or increased velocity. Movement of adjustment device 82 tightens and loosens velocity adjustor 252 , thereby allowing adjustment of marker 50 between the upper velocity setting and lower velocity setting. As with the representative form set forth with respect to FIGS. 3 a - 3 c and 9 , movement of adjustment device 82 is prevented from occurring above or below the upper velocity setting and lower velocity setting.
- FIG. 12 yet another form of marker 50 is illustrated that includes a velocity adjustment mechanism 300 .
- a first velocity adjustor 302 is used to set marker 50 to operate at the maximum or upper velocity setting. This is accomplished by adjusting the tension or force applied to hammer 122 by spring 124 similar to the manner described above.
- velocity adjustment mechanism 300 is positioned such that a gas chamber blocker 304 is located in a fully closed or forward position.
- the outer diameter of gas chamber blocker 304 includes a seal 306 that forms a fluid tight seal with a rear gas chamber 308 in bolt 112 .
- a rear portion of bolt 112 includes an aperture 310 running from an open end 312 of bolt 112 to rear gas chamber 308 .
- a rod 314 is connected with gas chamber blocker 304 and runs through the rear end of bolt 112 out of open end 312 .
- a portion 316 of the rear end of bolt 112 contains internal threads and a portion 318 of the end of rod 314 contains external threads.
- An adjustment knob 320 is connected with the exposed end of rod 314 .
- Adjustment knob 320 is used to screw rod 314 in and out of bolt 112 .
- gas chamber blocker 304 blocks or closes off chamber 308 .
- valve 126 is configured to release a set amount of compressed gas at a set pressure.
- the bolt air chamber, or total size of gas passage 116 increases with the rearward adjustment of rod 314 , moving gas chamber blocker 304 further back into gas chamber 308 , the velocity of the paintball during a firing operation decreases. This allows user 10 to adjust marker 50 to expel paintballs between the upper velocity setting and a lower velocity setting through the adjustment of knob 320 .
- yet another representative marker 50 is disclosed that includes a velocity adjustment mechanism 350 .
- This form is similar to that disclosed with respect to FIG. 12 except that instead of the volume adjustment occurring in connection with bolt 112 , it takes place with respect to valve 126 .
- velocity adjustment mechanism 350 can be used to adjust the velocity setting between the upper velocity setting and the lower velocity setting.
- a forward end of body 56 includes a longitudinal bore 354 that houses valve 126 .
- valve plug 356 is secured in bore 354 that defines a rear gas chamber 358 b and a forward gas chamber 358 a , which together define a gas storage chamber.
- valve plug 356 includes an outer threaded portion 360 that is threaded into an internally threaded portion 362 of bore 354 .
- Valve plug 356 also includes a spring retention member 364 that includes an aperture 366 .
- An end 368 of spring 129 rests against a respective surface of spring retention member 364 .
- At least one seal 369 is used to provide a fluid tight seal between bore 354 and valve plug 356 .

Description
- The present application is a continuation of U.S. patent application Ser. No. 12/069,086 filed on Feb. 7, 2008 that issued as U.S. Pat. No. 7,806,113 on Oct. 5, 2010, which is hereby incorporated by reference in its entirety.
- The present invention relates generally to compressed gas projectile accelerators and more particularly, to compressed gas projectile accelerators configured to allow players to select one of a plurality of velocity settings on the fly during play without the use of tools.
- In the sport of paintball, the maximum velocity at which projectiles are permitted to be expelled from the barrel of a paintball gun or marker is tightly controlled in both recreational and tournament play. Most tournaments and recreational paintball venues only permit a paintball marker to shoot paintballs at a maximum velocity of 300 feet per second (“FPS”). All markers are subjected to testing by chronographs before and sometimes after a tournament round or match. Some tournaments even randomly take chronograph readings of players' markers during actual tournament play. Shooting a hot marker, one that shoots paintballs at over 300 FPS, can subject a player or team to disqualification, a loss of points, or the player not being allowed on the field.
- Current paintball markers provide methods to adjust the speed at which a projectile is expelled from the marker. However, once the speed of the marker is adjusted to just below the maximum permitted velocity setting, the marker is not capable of being easily readjusted without the use of a tool, such as an allen wrench. Carrying tools that can be used to adjust marker velocity settings onto the field is strictly prohibited. As such, the paintball marker is only capable of being adjusted to operate on the field at one set velocity setting.
- One embodiment of the present application discloses a compressed gas projectile accelerator that is capable of expelling projectiles at a plurality of user selected velocity settings that do not exceed a maximum allowed velocity setting. Other embodiments include unique apparatus, devices, systems, and methods for expelling projectiles from a compressed gas projectile accelerator at user selected varying velocities so that users are capable of lobbing projectiles at targets as well as shooting straight at targets. Further embodiments, forms, objects, features, advantages, aspects, and benefits of the present application shall become apparent from the detailed description and figures included herewith.
- The figures are not necessarily to scale, emphasis instead being placed upon illustrating the principles of the invention. Moreover, in the figures, like reference numerals designate corresponding parts throughout the different views.

- Referring to
FIG. 1 , auser 10 is illustrated firing projectiles or paintballs at tworespective targets paintball marker 14.User 10 is shooting attarget 12 a with amarker 14 that is set or configured to expel paintballs attarget 12 a at an upper velocity setting, which in this form comprises the maximum allowable velocity setting of 300 FPS. As illustrated, sinceuser 10 is a substantial distance fromtarget 12 a, thus requiring the paintball to travel a greater distance (e.g. −200 feet), the paintball tends to travel along somewhat of an arced path after traveling a predetermined distance due to the force of gravity on the paintball. - As further illustrated,
user 10 is somewhat closer to target 12 b (e.g. −80 feet) who is hiding behind anobstacle 16, which is illustrated as a barrel for representative purposes only. Ifuser 10 fires a paintball attarget 12 b withmarker 14 set at the upper velocity setting, it would be extremely difficult, if not impossible, foruser 10 to hittarget 12 b due to the fact thatobstacle 16 is providing cover fortarget 12 b. This is because the paintball will travel along a relatively straight path towardtarget 12 b thereby causing the paintball to strikeobstacle 16 and not target 12 b. Despite the effect that gravity has on the paintball, at the maximum allowed velocity setting, paintballs are expelled from themarker 14 along a relatively straight path over short distances, which are the typical distances encountered on the field when shooting at arespective target - If
user 10 was able to lower the velocity at which paintballs are expelled from the barrel ofmarker 14 to lets say, for example, 180 FPS, as well as adjust the angle of the barrel ofmarker 14 upward at a predetermined angle, the likelihood ofuser 10 being able to striketarget 12 b behindobstacle 16 with a paintball is greatly improved. This is because the paintball will travel along a substantially arcshaped path 18 as a function of the speed at which the paintball exits the barrel and the angle of the barrel. Therefore, as illustrated inFIG. 1 ,user 10 is capable of “lobbing” a paintball ontotarget 12 b thereby eliminating the player, which is illustrated astarget 12 b. - Referring to
FIG. 2 , arepresentative paintball marker 50 is illustrated that includes an on the flyvelocity adjustment mechanism 52.Velocity adjustment mechanism 52 is operably configured to allowuser 10 to manually and selectively adjust the velocity at which paintballs are expelled from abarrel 54 of themarker 50.Marker 50 is configured to expel projectiles frommarker 50 at a range of velocities ranging from an upper velocity setting to a lower velocity setting. In one form, the upper velocity setting corresponds to the maximum velocity at which a paintball is allowed to be expelled frombarrel 54, which may be 300 FPS for example. Further, in one form, the lower velocity setting corresponds to the lowest possible velocity setting at whichmarker 50 is capable of expelling a paintball frombarrel 54. As those skilled in the art would recognize, different user preferred upper and lower velocity settings may be utilized in various other forms of the present invention. - In one form,
marker 50 includes a housing orframe body 56, agrip frame rail 58, a grip orgrip frame 60, atrigger mechanism 62, and afeed tube 64 for a projectile or paintball hopper 63 (SeeFIG. 1 ). As illustrated,body 56 is connected withgrip frame rail 58 or alternativelygrip frame rail 58 may be an integral part ofbody 56.Barrel 54 is connected with one respective end ofbody 56 and, in this illustrative form,velocity adjustment mechanism 52 is connected with the opposite end ofbody 56.Feed tube 64, which a paintball hopper (not shown) is removably connected with and feeds paintballs tomarker 50, is also connected with or formed as part ofbody 56.Trigger mechanism 62 is movably connected withgrip frame rail 58 and is configured to, with each trigger pull, expel a paintball from barrel 54 (at least in semi-automatic firing mode). In automatic firing mode, a plurality of paintballs are expelled frombarrel 54. - In another representative form, an electro-
pneumatic marker 50 is disclosed that includes anelectronic circuit board 66 and apower source 68. Although illustrated as being housed ingrip frame 60, it should be appreciated thatcircuit board 66 andpower source 68 may be housed in other locations ofmarker 50.Power source 68 is connected withcircuit board 66 and provides power tocircuit board 66. Electro-pneumatic marker 50 includes atrigger sensor 70 that is connected withcircuit board 66. A velocity orspeed sensor 72 and asolenoid valve 74 are also connected withcircuit board 66.Speed sensor 72 could comprise a laser, an optical eye, a LED speed sensor, or any other suitable type of speed sensor. As set forth in greater detail below, in this form, avelocity controller 76 is also connected withcircuit board 66. - Referring collectively to
FIGS. 3 a-3 c, a rear view ofmarker 50 is depicted to better illustrate one form ofvelocity adjustment mechanism 52. In this form,velocity adjustment mechanism 52 includes amain velocity adjustor 80.Main velocity adjustor 80 is configured to adjust a velocity setting ofmarker 50. In particular,main velocity adjustor 80 is configured to adjustmarker 50 so thatmarker 50 cannot expel paintballs above a predetermined upper or maximum velocity setting, which, for illustrative purposes only, is at or below 300 FPS. In this illustrative example,main velocity adjustor 80 comprises an allen head screw configured to adjustably control the upper velocity setting ofmarker 50. For example, adjustment ofmain velocity adjustor 80, by tightening or looseningmain velocity adjustor 80, increases or decreases the maximum velocity setting ofmarker 50. -
Velocity adjustment mechanism 52 includes an adjustment device ormember 82 that is connected withmain velocity adjustor 80. In this form,adjustment device 82 comprises a lever selector that is secured tomain velocity adjustor 80 with a retention member or setscrew 84.Adjustment device 82 includes anaperture 85 that fits around an outside diameter ofmain velocity adjustor 80. Oncemain velocity adjustor 80 is set to causemarker 50 to function at the user preferred or authorized upper velocity setting, which is just below 300 FPS in this example,lever selector 82 is positioned about adial 86 in a user selected position and then setscrew 84 is used to tightlysecure lever selector 82 tomain velocity adjustor 80. In this example, as illustrated inFIG. 3 a,user 10 has selected a twelve o-clock position forlever selector 82 as the setting for the maximum or upper velocity setting. - In order to prevent
user 10 from being able to turnlever selector 82 clockwise, thereby increasing the velocity at which a projectile may be expelled,lever selector 82 must be restricted. As previously discussed, any velocity above the upper or maximum velocity setting would causemarker 50 to be viewed as a “hot marker” as understood by those skilled in the art. In this example, dial 86 includes a plurality ofapertures 88 that are positioned around a circumference or perimeter ofdial 86. A blockingpin 90 is positioned or placed in arespective aperture 88 immediately next to lever 82 to preventlever selector 82 from being rotated any further in the clockwise direction. As such, this preventsuser 10 from being able to adjust the velocity setting ofmarker 50 above the upper velocity setting. This is an important feature asuser 10 would not be allowed to usemarker 50 if he/she was capable of adjustingmarker 50 to shoot above the maximum allowed velocity setting by simply movinglevor selector 82. - In this form, as
user 10 rotateslever selector 82 counterclockwise, the velocity at which paintballs are expelled frombarrel 54 ofmarker 50 begins to decrease. For example, at the setting illustrated inFIG. 3 b,marker 50 is set to expel paintballs at approximately 215 FPS. Thefurther lever selector 82 is adjusted counterclockwise, the velocity at which paintballs are expelled frommarker 50 decreases until, as illustrated inFIG. 3 c,lever selector 82 reaches a lower velocity setting. InFIG. 3 c, the lower velocity setting is controlled by placement of a blockingpin 92 in another user selectedaperture 88 ofdial 86. - During operation,
lever selector 82 will hit or bump up againstpins lever selector 82 to be adjusted any further beyond the upper and lower velocity settings.Selector 82 may also include a detainment mechanism, which is adetent 94 in this example, that is located in alignment withapertures 88 ondial 86 to help temporarily secure theselector 82 in place once a velocity setting is chosen byuser 10.Pins lever selector 82 beyond the upper and lower velocity settings.Apertures 88 may be threaded and in one form, dial 86 is connected tobody 56 ofmarker 50 and in another form, dial 86 is formed as an integral part ofbody 56 or other components ofmarker 50 disclosed herein. - Referring to
FIG. 4 a, a side view of one illustrative form ofmarker 50 is illustrated showingvelocity adjustment mechanism 52 located directly onmarker 50. In this form,velocity adjustment mechanism 52 is illustrated as being located or positioned at the back or rear ofbody 56; however, those skilled in the art should appreciate that velocity adjustment mechanism may be located at several other positions onmarker 50.Marker 50 includes a compressedgas source 100, which may contain compressed air, CO2, nitrogen, or any other type of suitable compressed gas, which is removably connected with atank adapter 102 ofmarker 50. The compressed gas stored insource 100 is used to selectively expel projectiles frombarrel 54 ofmarker 50. - In this illustrated form, a
gas line 104 connects an output oftank adapter 102 to apressure regulator 106. Compressed gas from compressedgas source 100 is in communication withpressure regulator 106.Pressure regulator 106 prevents gas pressures from rising above a predetermined threshold level before enteringmarker 50, to prevent damage of the internal components ofmarker 50.Pressure regulator 106 includes anadjustment knob 108 that provides for adjustment of one or more operating parameters ofpressure regulator 106. - Referring to
FIG. 4 b, in this representative form,velocity adjustment mechanism 52 is configured as an integral part ofpressure regulator 106. As such, movement ofselector 82 onregulator 106 between an upper set point and a lower set point will causemarker 50 to expel projectiles frombarrel 54 between a maximum or upper velocity setting and a minimum or lower velocity setting. - Referring to
FIG. 4 c, in this representative form,velocity adjustment mechanism 52 has been incorporated as a component oftank adapter 102. Movement ofselector 82 ontank adapter 102 between an upper set point and a lower set point will causemarker 50 to expel projectiles frombarrel 54 between an upper velocity setting and a lower velocity setting. All of the features discussed above with reference toFIGS. 3 a-3 c are hereby incorporated by reference into the representative forms set forth inFIGS. 4 b and 4 c. - Referring to
FIG. 5 , in this representative form,velocity adjustment mechanism 52 is mounted on a side ofmarker 50.Selector 82 is illustrated as being set at the maximum velocity setting. In this form, rotation ofselector 82 clockwise causesmain velocity adjustor 80 to block a gas passage inmarker 50 thereby allowinguser 10 to incrementally reduce the velocity of paintballs that are expelled frombarrel 54. For the sake of brevity, those skilled in the art should recognize that the remaining features ofmarker 50 andvelocity adjustment mechanism 52 are the same as those set forth with respect toFIGS. 3 a-3 c. - Referring to
FIG. 6 , another representative form ofmarker 50 is illustrated that includes avelocity adjustment mechanism 110. In this representative example,marker 50 includes abolt 112 that travels back and forth along a longitudinal axis in a bolt chamber or bore 114 insidebody 56 ofmarker 50.Bolt 112 includes agas passage 116 through which compressed gas passes in order to expel paintballs frombarrel 54. Asbolt 112 travels forward, agas port 118 inbolt 112 reaches avalve passage 120. During operation, oncetrigger mechanism 62 is pressed,trigger mechanism 62 releases ahammer 122 that travels forward under the pressure or force provided by ahammer spring 124. After traveling a predetermined distance,hammer 122 strikes a respective end of avalve 126, thereby actuatingvalve 126. - Actuation of
valve 126 causes compressed gas, which is stored in a compressedgas storage chamber 128 on an opposite side ofvalve 126, to vent throughvalve passage 120 intogas passage 116 ofbolt 112 throughgas port 118. It should be appreciated thatbolt 112 and hammer 122 move together andgas port 118 is positioned onbolt 112 such thatgas port 118 is aligned withvalve passage 120 whenhammer 122strikes valve 126. A bolt andhammer connecting pin 127 is used to connectbolt 112 withhammer 122. As such, compressed gas is permitted to travel from compressedgas storage chamber 128 tovalve passage 120 and then intogas passage 116 ofbolt 112 viagas port 118. This compressed gas is then used to expel a paintball from thebarrel 54. After compressed gas is expelled fromchamber 128, aspring 129 connected to an end ofvalve 126forces valve 126 shut or closed, thereby stopping the flow of compressed gas throughvalve passage 120. At the same time compressed gas is passed throughpassage 120, compressed gas is also directed to ahammer chamber 131, which causeshammer 122 and bolt 112 to recoil for another shot. - As illustrated in
FIG. 6 , anadjustable relief valve 130 is a venting mechanism connected with an exposed end ofbolt 112.Adjustable relief valve 130 is used to control or limit the pressure that is supplied from the flow of compressed gas utilized to expel paintballs frombarrel 54. As such, when compressed gas is introduced togas passage 116 ofbolt 112, compressed gas travels forward to expel a paintball frombarrel 54 and backwards towards venting mechanism onend 134 ofbolt 112. Depending on the desired velocity setting, a predetermined amount of compressed gas will vent throughvelocity adjustment mechanism 110.Adjustable relief valve 130 includes anadjustment mechanism 136, a knob or wheel in this illustrative example, that allowsuser 10 to adjust velocity settings between the maximum or upper velocity setting and the minimum or lower velocity setting. - Referring to
FIG. 7 , in yet another illustrative form,marker 50 includes avelocity adjustment mechanism 110 located onbody 56. In particular,velocity adjustment mechanism 110 is a venting mechanism located at anend 150 ofbarrel 54. In this form,bolt 112 does not travel completely to end 150 ofbarrel 54. As such, a gap exists between anend 152 ofbolt 112 and end 150 ofbarrel 54 during a firing operation such that a seal is not formed betweenbarrel 54 andbolt 112.Body 56 includes agas port 154 that is connected with a venting mechanism, which is anadjustable relief valve 156 in this form. As with the previous form, during a firing operation, compressed gas travels throughgas passage 116. A predetermined amount of this compressed gas is redirected intogas port 154 and is vented throughadjustable relief valve 156.Velocity adjustment mechanism 110 includes aknob 158 that is used byuser 10 to control the amount of compressed gas that is released fromadjustable relief valve 156.Adjustable relief valve 156 is thus capable of allowingmarker 50 to expel projectiles between a maximum or upper velocity setting and a minimum or lower velocity setting. - Referring to
FIG. 8 , in yet another form,bolt 112 includes agas passage 116 that includesinput port 118 and anoutput port 160, in addition to aport 162 used to expel paintballs frombarrel 54.Body 56 includes agas port 164 that aligns with output port or vent 160 ofbolt 112 during a firing operation and redirects a predetermined amount of compressed gas to a venting mechanism. As with the previous forms,marker 50 includes avelocity adjustment mechanism 166, which comprises anadjustable relief valve 168 that acts or functions as the venting mechanism. In this form,velocity adjustment mechanism 166 is located behindfeeder 64 inbody 56.Adjustable relief valve 168 includes aknob 170 that is used byuser 10 to control the amount of compressed gas that is released fromadjustable relief valve 168.Adjustable relief valve 168 is thus capable of allowingmarker 50 to expel projectiles between a maximum velocity setting and a minimum velocity setting. - Referring to
FIG. 9 , a portion of anotherrepresentative marker 50 is illustrated that includes avelocity adjustment mechanism 180. In this representative form, a hammerspring end cap 182 is connected with anend 184 ofbody 56. Hammerspring end cap 182 is threadably connected withbody 56 or friction fit withbody 56. A threadedend 185 of amain velocity adjustor 186 is secured in a threadedaperture 188 of hammerspring end cap 182.Main velocity adjustor 186 has an unthreadedend 190 that extends from threadedend 185 into thebody 56 ofmarker 50 and includes a spring retention collar 192. Anend 194 ofhammer spring 124 fits around unthreadedend 190 ofmain velocity adjustor 186 and rests against collar 192. A portion ofmain velocity adjustor 186 fits within aretention aperture 196 ofend cap 182. - In this form,
main velocity adjustor 186 is used to set the maximum or upper velocity setting by adjustment ofmain velocity adjustor 186 inend cap 182.Main velocity adjustor 186 is used to adjust the tension onhammer spring 124. The more tension that is applied to hammer spring 124 (i.e.—by screwingmain velocity adjustor 186 further into end cap 182), theharder hammer 122strikes valve 126 during a firing operation. Theharder hammer 122strikes valve 126, thelonger valve 126 is activated and a greater volume of compressed gas is released fromvalve 126, thereby expelling paintballs frombarrel 54 at a higher velocity. Likewise, looseningmain velocity adjustor 186, which lessens the tension applied to hammer 122 byspring 124, causes hammer 122 to strikevalve 126 with less force during a firing operation. This causes a quicker activation ofvalve 126 and a release of a lesser gas volume during a firing operation, thereby expelling paintballs frombarrel 54 at a lower velocity. - As with the form illustrated in
FIGS. 3 a-3 c, this form may include an adjustment device 82 (e.g.—a selector lever). Oncemain velocity adjustor 186 has been set to expel projectiles at an upper velocity level or setting,selector 82 may be connected with or adjusted onmain velocity adjustor 186. Althoughdial 86 is not included in this form, it could be connected withend cap 182. In this form,end cap 182 includesapertures 88. As with the forms disclosed inFIGS. 3 a-3 c, pins or setscrews apertures 88 to ensure thatselector 82 cannot be adjusted above the upper velocity setting or below the minimum or lower velocity setting. SeeFIGS. 3 a-3 c. Setscrew 84 is used to secureselector 82 tomain velocity adjustor 186. - Referring to
FIG. 10 , in this form,marker 50 includes avelocity adjustment mechanism 200 that adjusts the tension applied byspring 129 tovalve 126. As those skilled in the art would recognize, thevelocity adjustment mechanism 200 can be configured additionally onmarker 50 with or without the above describedmain velocity adjustor 186.Velocity adjustor 202 is positioned in a valvespring retention member 204.Retention member 204 is connected withbody 56 and is positioned inchamber 128.Velocity adjustor 202 includes a threadedend 206, a sealingmember 208, anextension member 210, and acollar 212. Threadedend 206 is threaded into an internally threadedaperture 214 ofretention member 204 and transitions into sealingmember 208. Sealingmember 208 includes one ormore seals 216 that form a fluid tight seal between sealingmember 208 and aninternal bore 218 ofretention member 204.Extension member 210 extends away from sealingmember 208 insideinternal bore 218 and transitions intocollar 212. Anend 220 ofspring 129 is connected withcollar 212 and anopposite end 222 ofspring 129 is connected with an end ofvalve 126. -
Velocity adjustment mechanism 200 works in conjunction withhammer 122 in this form.Velocity adjustment mechanism 200 is used to adjust the force applied to the end ofvalve 126. The more force that is applied tovalve 126, thefaster valve 126 shuts after being struck byhammer 122. As such, as threadedend 206 is tightened intoretention member 204, more force is applied tovalve 126 byspring 129. Likewise, as threadedend 206 is loosened fromretention member 204, less force is applied tovalve 126. Thefaster valve 126 closes, the less volume of compressed gas is allowed to pass throughvalve 126 to expel projectiles frombarrel 54 ofmarker 50. As such, adjustment of threadedend 206 to a predetermined location or setting allowsuser 10 to set an upper velocity setting. As with the previous embodiments,velocity adjustment device 82 may then be used to raise and lower the velocity at which paintballs are expelled frombarrel 54. All other features of this form remain the same as previously set forth with respect toFIGS. 3 a-3 c and 9. - Referring to
FIG. 11 , in this form,marker 50 includes avelocity adjustment mechanism 250 that adjusts the volume of gas and the tension onspring 129 to control the force at which a paintball is expelled frombarrel 54.Velocity adjustment mechanism 250 includes avelocity adjustor 252 that is threaded intobody 56 ofmarker 50. In particular,velocity adjustor 252 is threaded intochamber 128 ofmarker 50.Velocity adjustor 252 includes a threadedsegment 254, anextension segment 256, and aspring receiving segment 258. Threadedsegment 254 is threaded into an internally threadedsegment 260 ofbore 253. -
Extension segment 256 extends away from threaded segment 254 a predetermined distance intobore 253. At an opposite end ofextension segment 256 is aspring receiving segment 258.Spring receiving segment 258 includes anaperture 262 that receives afirst end 264 ofspring 129. Asecond end 266 ofspring 129 is connected with or engages anend 268 ofvalve 126. At least oneseal 278 is positioned betweenspring receiving segment 258 and bore 253 to provide a fluid tight seal forchamber 128, which is defined bybore 253,spring receiving segment 258 andvalve 126. - In this form,
chamber 128 comprises a compressed gas storage chamber that is refilled with compressed gas after each shot. The compressed gas has a predetermined pressure level, which is controlled byregulator 106, and a predetermined volume. While the pressure level does not change,velocity adjustment mechanism 250 is configured to change the volume or amount of compressed gas that is stored inchamber 128. In addition, the tension onspring 129 is also adjusted which, in turn, changes the amount of force applied to end 266 ofspring 129. - During setup,
velocity adjustor 252 is configured to allowmarker 50 to expel paintballs frombarrel 54 at a maximum or upper velocity setting. As with the previous forms, adjustment device orselector 82 allowsuser 10 to adjust operation ofmarker 50 between the upper velocity setting and the lower velocity setting. Tightening, or screwing invelocity adjustor 252, increases the tension onspring 129, thereby causingvalve 126 to close faster whenhammer 122strikes valve 126, as well as decreases the volume ofchamber 128. - Loosening
velocity adjustor 252 decreases the force placed onvalve 126 and increases the volume of chamber 128 (i.e.—thereby allowing more compressed gas into chamber 128), which allows paintballs to be expelled frombarrel 54 at a higher or increased velocity. Movement ofadjustment device 82 tightens and loosensvelocity adjustor 252, thereby allowing adjustment ofmarker 50 between the upper velocity setting and lower velocity setting. As with the representative form set forth with respect toFIGS. 3 a-3 c and 9, movement ofadjustment device 82 is prevented from occurring above or below the upper velocity setting and lower velocity setting. - Referring to
FIG. 12 , yet another form ofmarker 50 is illustrated that includes avelocity adjustment mechanism 300. In this form, afirst velocity adjustor 302 is used to setmarker 50 to operate at the maximum or upper velocity setting. This is accomplished by adjusting the tension or force applied to hammer 122 byspring 124 similar to the manner described above. During this adjustment,velocity adjustment mechanism 300 is positioned such that agas chamber blocker 304 is located in a fully closed or forward position. The outer diameter ofgas chamber blocker 304 includes aseal 306 that forms a fluid tight seal with arear gas chamber 308 inbolt 112. - A rear portion of
bolt 112 includes anaperture 310 running from anopen end 312 ofbolt 112 torear gas chamber 308. Arod 314 is connected withgas chamber blocker 304 and runs through the rear end ofbolt 112 out ofopen end 312. Aportion 316 of the rear end ofbolt 112 contains internal threads and aportion 318 of the end ofrod 314 contains external threads. Anadjustment knob 320 is connected with the exposed end ofrod 314. -
Adjustment knob 320 is used to screwrod 314 in and out ofbolt 112. Whenadjustment knob 320 is in the fully closed position,gas chamber blocker 304 blocks or closes offchamber 308. Asadjustment knob 320 is unscrewed or adjusted outwardly, more ofchamber 308 becomes exposed thereby increasing the total volume ofgas passage 116. In this form, during a firing operation,valve 126 is configured to release a set amount of compressed gas at a set pressure. As the bolt air chamber, or total size ofgas passage 116, increases with the rearward adjustment ofrod 314, movinggas chamber blocker 304 further back intogas chamber 308, the velocity of the paintball during a firing operation decreases. This allowsuser 10 to adjustmarker 50 to expel paintballs between the upper velocity setting and a lower velocity setting through the adjustment ofknob 320. - Referring to
FIG. 13 , yet anotherrepresentative marker 50 is disclosed that includes avelocity adjustment mechanism 350. This form is similar to that disclosed with respect toFIG. 12 except that instead of the volume adjustment occurring in connection withbolt 112, it takes place with respect tovalve 126. Once the upper velocity setting is set usingfirst velocity adjustor 302, as described above,velocity adjustment mechanism 350 can be used to adjust the velocity setting between the upper velocity setting and the lower velocity setting. In this form, a forward end ofbody 56 includes alongitudinal bore 354 that housesvalve 126. - A
valve plug 356 is secured inbore 354 that defines arear gas chamber 358 b and aforward gas chamber 358 a, which together define a gas storage chamber. In this form,valve plug 356 includes an outer threadedportion 360 that is threaded into an internally threadedportion 362 ofbore 354.Valve plug 356 also includes aspring retention member 364 that includes anaperture 366. Anend 368 ofspring 129 rests against a respective surface ofspring retention member 364. At least oneseal 369 is used to provide a fluid tight seal betweenbore 354 andvalve plug 356. Avalve 370, which may comprise a solenoid valve, is used to selectively supply compressed gas to therear gas chamber 358 b andforward gas chamber 358 a. -
Velocity adjustment mechanism 350 includes avelocity adjustor 352.Velocity adjustor 352 includes an outer threadedportion 372 that engages an inner threadedportion 374 ofvalve plug 356.Velocity adjustor 352 includes agas chamber blocker 376. An outer diameter ofgas chamber blocker 376 includes aseal 378 that forms a fluid tight seal betweengas chamber blocker 376 and an inner wall ofrear gas chamber 358 b.Velocity adjustor 352 also includes anadjustment knob 380 that extends or is positioned outwardly from the end ofvalve plug 356. - When
marker 50 is being adjusted for use or play,velocity adjustor 352 is secured or screwed all the way intorear gas chamber 358 b as far as possible.Valve plug 354 includes agas supply aperture 382 that is in alignment with agas supply passage 384. In this example,gas chamber blocker 376 is in approximate alignment withgas supply aperture 382. Oncevelocity adjustor 352 is in the forward most position,first velocity adjustor 302 is used to set the upper velocity setting ofmarker 50. - During play,
user 10 can lower the velocity setting ofmarker 50 by unscrewing or adjusting the position ofvelocity adjustor 352. Adjusting the position ofvelocity adjustor 352 outwardly by turningknob 380, increases the volume ofrear gas chamber 358 b. Since compressed gas is supplied to the gas storage chamber, which as previously set forth comprises reargas storage chamber 358 b and forwardgas storage chamber 358 a, at a set pressure and set volume, increasing the volume of the gas storage chamber causes a decrease in velocity of paintballs that are expelled frombarrel 54. - Referring to
FIG. 14 , a portion of yet another form ofmarker 50 is illustrated that includes another representative form of avelocity adjustment mechanism 400.Velocity adjustment mechanism 400 includes a dial selector, which in this form comprises an adjustablegas passage blocker 402 positioned in aslot 404 ofbody 56.Valve 126 includes avalve body 406 that includes a gas port 408. Adjustablegas passage blocker 402 is positioned inslot 404 ofbody 56 on aswivel pin 410. As set forth in greater detail below, as gas passes fromchamber 128 through port 408 ofvalve 126, the gas also passes through adjustablegas passage blocker 402 before enteringinput port 118 ofgas passage 116 inbolt 112. - Referring to
FIGS. 15 a-c, which depicts top cross sectional views ofmarker 50 along hash A-A inFIG. 14 , a more illustrative view of adjustablegas passage blocker 402 is illustrated. A portion ofgas passage blocker 402 protrudes outwardly from aside 412 ofbody 56. Adjustablegas passage blocker 402 includes a plurality ofpassages 414 positioned about a circumference or perimeter of adjustablegas passage blocker 402. Eachpassage 414 has a different diameter or size. Main velocity adjustor 302 (seeFIG. 12 ) is used to set the upper velocity setting ofmarker 50 and adjustablegas passage blocker 402 is used to lower the velocity setting to different settings as a function of whichpassage 414 is selected. - As set forth above,
gas passage blocker 402 includespassages 414 that are sized according to the amount of restriction that is desired. For example, inFIG. 15 a, thelargest diameter passage 414 is aligned with gas port 408 orvalve 126. As such,marker 50 is set at the upper velocity setting.FIG. 15 b represents a middle setting andFIG. 15 c represents the lower velocity setting. Anadjustment member 416 protrudes outwardly fromgas passage blocker 402. A cutaway orslot 418 is located inbody 56 that provides a passageway foradjustment member 416 to travel through. - Referring to
FIG. 16 , in yet another form,marker 50 includes avelocity adjustment mechanism 450 that comprises abolt passage blocker 452 that is designed to partially blockport 118 ofbolt 112.Bolt passage blocker 452 is connected with arod 454 that fits within anaperture 456 inbolt 112.Bolt passage blocker 452 fits within a retainingaperture 458 bored inbolt 112. Anend portion 460 ofrod 454 includes an externally threadedportion 462 that engages an internally threadedportion 464 ofbolt 112. The end ofrod 454 is connected with anadjustment knob 466. -
Bolt passage blocker 452 is configured to blockport 118 ofbolt 112 such that gas is restricted from flowing intopassage 116 ofbolt 112. Asknob 466 is screwed in and out,bolt passage blocker 452 adjusts to either increasingly ordecreasingly block port 118. As a result, the velocity at which paintballs are expelled frombarrel 54 can be adjusted between a maximum velocity setting and a minimum velocity setting. The maximum velocity setting may be configured onmarker 50 by usingmain velocity adjustor 302, as previously set forth. When the maximum velocity is set,bolt passage blocker 452 is set in a fully retracted state or position so thatuser 10 cannot increase the velocity while on the field to an excessive velocity setting. - Referring to
FIG. 17 , another representative form ofmarker 50 is illustrated that includes avelocity adjustment mechanism 500. In this form, the position ofbolt 112 is adjusted such that, during a firing operation,port 118 ofbolt 112 is misaligned withgas passage 120. As such, the misalignment ofport 118 restricts the flow of compressed gas topassage 116, thereby slowing down the velocity of paintballs being expelled frombarrel 54. The bolt andhammer connecting pin 127 is positioned inaperture 510 inbolt 112. One end of arod 502 is connected with bolt andhammer connecting pin 127. Another end ofrod 502 is connected with aknob 506.Rod 502 is positioned in anaperture 504 inbolt 112. Anend portion 508 ofrod 502 includes external threads that mate with internal threads inaperture 504. With bolt andhammer connecting pin 127 joined to hammer 122, rotation ofrod 502 withknob 506 repositionsbolt 112 back and forth along a longitudinal axis in bolt chamber or bore 114 insidebody 56 ofmarker 50. The maximum velocity is ready to set whenknob 506 is fully unscrewed and bolt 112 is in the forward most position. Then maximum velocity setting is configured onmarker 50 usingmain velocity adjustor 302, as previously set forth. - As
knob 506 is screwed in, bolt 112 moves rearward, thereby causingport 118 to become misaligned withpassage 120. Themore port 118 becomes misaligned withpassage 120, by adjustment ofbolt 112 on the bolt andhammer connecting pin 127 throughknob 506, the lower the velocity of paintballs expelled frombarrel 54 will be. In addition, whenbolt 112 is misaligned withpassage 120, some compressed gas will be vented throughfeed tube 64, thereby also lowering the velocity of the paintball. - Referring to
FIG. 18 , another representative form ofmarker 50 is illustrated that includes avelocity adjustment mechanism 550. In this form,velocity adjustment mechanism 550 creates controllable separation between apaintball 566 andbolt 112.Velocity adjustment mechanism 550 comprises apaintball repositioning member 552 that pushes paintballs further intobarrel 54 during a firing operation.Paintball repositioning member 552 is connected with arod 554 that passes throughgas passage 116 and anaperture 556 inbolt 112. Anend 558 ofbolt 112 includes an internally threadedportion 560 and anend 568 ofrod 554 includes an externally threadedportion 562 that threads into internally threadedportion 560. Aknob 564 is connected to end 568 ofrod 554 and allows adjustment ofball repositioning member 552. -
Ball repositioning member 552 is configured to push apaintball 566 intobarrel 54 at various depths. Thefurther paintball 566 is pushed out of the breech intobarrel 54, the greater the separation from saidbolt 112, thereby the slower orless velocity paintball 566 will be expelled frombarrel 54 during a firing operation.Knob 564 allowsuser 10 to adjust the depth at whichpaintball 566 is pushed intobarrel 54, thereby allowing adjustment of the velocity at whichpaintball 566 is expelled frombarrel 54 between an upper velocity setting and a lower velocity setting. As those skilled in the art would recognize, theball repositioning member 552 is for the controllable separation of thepaintball 566 from the compressed gas forces ofcompressed gas passage 116, ofbolt 112. - Referring to
FIG. 2 , in yet another form of the present invention, an electronicprojectile accelerator 50 is disclosed that includes an electronic velocity adjustment mechanism. Electronicprojectile accelerator 50 includes an electronic controller, which in this form comprises anelectronic circuit board 66 connected with apower source 68. Avelocity controller 76, which may comprise a push button control, a dial control, or any other suitable type of control, is connected with theelectronic circuit board 66 for allowing a user to selectively set a velocity setting at which projectiles are expelled from abarrel 54. - In one form, the velocity setting is not permitted to go above a predetermined maximum value. A solenoid or
solenoid valve 74 is connected with theelectronic circuit board 66. Theelectronic circuit board 66 is configured to control one or more operating parameters of thesolenoid 74 as a function of the velocity setting. - The electronic
projectile accelerator 50 further includes asensor 72 configured to permit determination of a velocity of a projectile exiting the electronicprojectile accelerator 50. Theelectronic circuit board 66 is adapted to adjust one or more operating parameters of the electronicprojectile accelerator 50, in one form, operating parameters ofsolenoid 74, as a function of the velocity determination and the velocity setting. - Another aspect of the present invention discloses a kit for retrofitting a compressed
gas projectile accelerator 50. The kit includes a velocity adjustment mechanism, as disclosed and described above with respect toFIGS. 1-18 , that is configured to allow the compressedgas projectile accelerator 50 to expel projectiles between a defined range of velocity settings. A velocity controller is included in the kit for allowing a user to selectively adjust the velocity adjustment mechanism to a respective velocity setting falling in the range of velocity settings. The exact components included in the kit will vary depending on the design of the compressedgas projectile accelerator 50, but will include one or more of the components described and set forth with respect toFIGS. 1-18 . - One form of the present invention discloses a compressed gas projectile accelerator. The compressed gas projectile accelerator includes a velocity adjustment mechanism configured to allow the compressed gas projectile accelerator to expel projectiles between a first velocity setting and a second velocity setting. The velocity adjustment mechanism includes a velocity controller configured to allow a user to selectively select a velocity setting falling between the first velocity setting and the second velocity setting.
- Another aspect of the present invention discloses a method, comprising the steps of a) configuring a compressed gas projectile accelerator to expel projectiles at a user selected velocity setting falling between a first velocity setting and a second velocity setting; and b) providing a velocity controller configured to manually allow a user to selectively choose a respective one of a plurality of velocity settings falling between the first and second velocity settings as desired by the user.
- Yet another aspect of the present invention discloses a compressed gas projectile accelerator, comprising a compressed gas source; a compressed gas releasing mechanism in communication with said compressed gas source for selectively releasing compressed gas to expel a projectile; and a projectile velocity controller configured to selectively expel projectiles at a manual user selected velocity setting falling within a range of velocity settings.
- A further aspect of the present invention discloses a projectile accelerator. The projectile accelerator includes a compressed gas source; a gas releasing mechanism in communication with the compressed gas source; a trigger mechanism for selectively controlling the gas releasing mechanism; and a velocity adjustor associated with the gas releasing mechanism for allowing a user of the projectile accelerator to selectively adjust the velocity at which a projectile is expelled from the projectile accelerator between an upper velocity setting and a lower velocity setting, where adjustment of the velocity adjustor from the upper velocity setting toward the lower velocity setting progressively causes projectiles to be expelled from the projectile accelerator in a lobbed manner.
- Another aspect of the present invention discloses an electronic projectile accelerator, comprising: an electronic circuit board; a velocity controller connected with the electronic circuit board for allowing a user to selectively set a velocity setting at which projectiles are expelled from a barrel, where the velocity setting is not permitted to go above a predetermined maximum value; and a solenoid connected with the electronic circuit board, where the electronic circuit board is configured to control one or more operating parameters of the solenoid as a function of the velocity setting.
