Definitions
- the present invention relates to the field of exercise equipment, and more in particular to an exercise device configured to provide an abdominal workout.
- exercise devices that support individuals in the performance of exercises are common and exist in many varieties.
- One type of exercise device is an abdominal exercise device, which supports an individual in the performance of abdominal exercises.
- the abdominal muscles are a group of 6 muscles that extend from various places on the ribs to various places on the pelvis. They provide movement and support to the trunk, and are often called the core muscles.
- An abdominal exercise device includes a frame and a knee support configured to support both of a user's knees when the user is in a kneeled position.
- the knee support is pivotally mounted to the frame, such that it swings with respect to the frame.
- a hand grip is attached to the frame.
- a user will kneel on the pivotally mounted knee support and grip the hand grip with their hands.
- the user holds their upper body in a relatively stationary position with respect to the frame. Then, by contracting their abdominal muscles, the user can pivot the knee support upon which their knees rest up toward the support, thereby providing their abdominal muscles with a work out.
- the frame is made of two secondary frames that can be adjustably positioned with respect to each other. These two secondary frames can be positioned in an open or a closed position. In an open position, the frame is configured to allow the user to perform abdominal exercises. In these closed position, the frame is reconfigured to occupy less space so that it may be easily stored.
- the exercise device also includes a forearm support positioned adjacent to the hand grip.
- the forearm support provides a user with additional upper body support while the user contracts their abdominal muscles to pivot the knee support up toward the hand grip.
- the exercise device further includes a resistance enhancer that increases an amount of force required to pivot the knee support with respect to the frame.
- the resistance enhancer is flexible cable that extends across the frame and engages the knee support.

- FIG. 1 illustrates a rear perspective view of an abdominal exercise device 10 according to one or more embodiments of the invention.
- Abdominal exercise device 10 includes a frame 12 .
- Frame 12 is formed of two secondary frames, a first frame 14 and a second frame 16 .
- Secondary frames 14 and 16 are pivotally attached to each other to form frame 12 .
- Secondary frames 14 and 16 each generally have a “U” shaped configuration.
- Secondary frames 14 and 16 are pivotally attached to each other to enhance the utility of frame 12 .
- Frames 14 and 16 are able to pivot between open and closed positions.
- Frame 12 is shown in an open position. When in an open position, frame 12 is configured to be utilized for abdominal exercises by a user.
- Frames 14 and 16 may then be pivoted such that they are parallel to each other, thereby greatly reducing the volume of space occupied by frame 12 .
- frame 12 is in the closed position. In the closed position, frame 12 occupies a minimum of space, thereby making it easier to store abdominal exercise device 10 .
- Hinges 18 are located on each side of frame 12 . Hinges 18 attach frames 14 and 16 together, thereby enhancing the structural stability of frame 12 . Further, hinges 18 limit the degree to which frames 14 and 16 can pivot with respect to each other. Hinges 18 are made of two members 20 that are pivotally joined to frames 14 and 16 by pins 22 and in the center of hinge 18 by pin 24 .
- Frames 14 and 16 are attached to each other by joints 26 .
- Joints 26 join frames 14 and 16 together and enable them to pivot with respect to each other.
- Frames 14 and 16 are shown to be made of shaped tubes. The use of shaped tubes is desirable due to their structural strength and ease of manufacture. However, other configurations of members may be used to form frames 14 and 16 that are well know and exist in many varieties.
- Upper body support 28 is attached to first frame 14 .
- Upper body support 28 includes a hand support 29 and a forearm support 30 , which individually and collectively form a torso support region.
- Upper body support 28 is also formed of shaped tubing.
- the tubing used for frames 14 and 16 as well as upper body support 28 can be formed of metal, plastic, a composite material, such as an epoxy coated carbon fiber material, or other structural material.
- Upper body support 28 may optionally be grasped by the user's arms or hands.
- upper body support 28 may optionally include a pad to support the forearms, chest and/or stomach or a user.
- a user support 32 also referred to as a knee support, is pivotally mounted to frame 12 .
- User support 32 swings with respect to frame 12 .
- frame 12 generally has an “A-frame” configuration, but can be of other configurations, such as a tripod, four legged support structure or other support structure that is able to pivotally support user support 32 for movement above the ground.
- User support 32 includes a knee pad 34 , which is attached to a third frame 36 .
- Third frame 36 is connected to pivot mounts 38 which are held into position by pins 39 .
- pins 39 couple joints 26 together to enable frames 14 and 16 to pivot with respect to each other.
- User support 32 generally has a “U” shape, but can have other configurations.
- user support 32 may simply take the form of a sled provided with rollers that roll within an arcuate track mounted on frame 12 .
- user support 32 can simply be a sled that is supported on an arcuate track having rollers. All that is required for user support 32 is some structure that can carry the knee pad 34 and enable arcuate movement of the knee pad 34 .
- the term “pivotal” movement should be broadly construed to encompass such arcuate movement, since such movement is typically about some axis of movement.
- Knee pad 34 is shown to have contours that conform to a user's two legs when they are positioned side by side. Knee pad 34 can be formed of a durable hard plastic that is contoured in the molding process. Alternatively, knee pad 34 may be formed of a rigid platform that is then covered with a spongy material, such as foam or other padding, along with a durable cover such as leather or a vinyl material. A contoured or padded surface increases the ergonomic utility of knee pad 34 . Specifically, as shown, a padded surface may be provided with a pair of spaced depressions or elongated channels for comfortably receiving the knees and/or shins of a user.
- Knee pad 34 is shown to comprise a single pad. Knee pad 34 can also comprise two separate pads (one for each knee and/or shin) that are operatively or structurally connected to enable them to move in unison.
- the user support 32 is constructed and arranged to carry all or substantially all of the user's body weight.
- the upper body support 28 is spaced away from the user's upper body so as to only provide a stabilizing mechanism when grasped by the user.
- the upper body support 28 is close to the user and can support some of the user's upper body weight. All that is required of upper body support 28 is to enable the upper body of a user to be supported during arcuate movement of knee pad 34 .
- hand support 29 and forearm support 30 provide the user with the ability to stabilize and hold their torso in a stationary position with respect to frame 12 .
- the user is able to pivot or swing knee support 32 up toward upper body support 28 .
- the user is able to pivot or swing knee support 32 up toward upper body support 28 by contracting their abdominal muscles. By contracting their abdominal muscles to move knee support 32 , the user is performing abdominal exercises.
- a user's upper body can remain stationary while the user's lower body moves.
- the abdominal exercise device 10 enables a user swing their lower body by contracting their abdominal muscles while holding their upper body in a relatively stable configuration that does not require the user to swing his head or neck around.
- each side of third frame 36 Attached to each side of third frame 36 are pulleys 40 that are pivotally mounted to third frame 36 by means of pins 42 .
- a flexible cable 44 is attached by pins 46 at looped ends 48 to frames 14 and 16 .
- Flexible cable 44 together with pulleys 40 , form a resistance enhancer, also referred to as a damper mechanism, that increases the force required for a user to pivot or swing knee support 32 up towards upper body support 28 .
- Loop ends 48 are formed in flexible cable 44 by means of fasteners 50 .
- Flexible cables 44 may be formed of elastic chords. A user can increase the amount of force required to pivot or swing knee support 32 up toward upper body support 28 by coupling flexible cable 44 to one of the pulleys 40 .
- Two pulleys 40 are shown.
- the resistance enhancer or damper mechanism can also take the form of, just for example: (1) an adjustable friction device, for example at the pivot hinge 38 of user support 32 or at any region of the user support 32 to generate friction damping; (2) a magnetic or electromagnetic damper mechanism as known in the exercise industry; (3) a friction belt and/or flywheel arrangement; or (4) a handle or lever to enable an exercise trainer or user to exert a dampening force manually on user support 32 .
- damping adjusters may also optionally be provided to adjust the amount of friction, or magnetic damping force that is applied.
- FIG. 2 illustrates a perspective view of an abdominal exercise device according to one or more embodiments of the invention.
- Abdominal exercise device 10 is shown having a pair of pulleys 40 and a flexible cable 44 on each side of knee support 32 .
- Each flexible cable 44 provides a degree of resistance to the pivotal movement of knee support 32 .
- the first level of resistance is where neither flexible cable 44 is placed on a pulley 40 , thereby placing no resistance on knee support 32 .
- a second level of resistance is placed on knee support 32 by placing a single flexible cable 44 on the lowest pulley 40 .
- a third level of resistance is placed on knee support 32 by placing a single flexible cable 44 on the highest pulley 40 .
- a fourth level of resistance is placed on knee support 32 by placing both flexible cables 44 each on the lowest pulley 40 .
- a fifth level of resistance is placed on knee support 32 by placing one flexible cable 44 on the lowest pulley 40 and the other flexible cable 44 on the highest pulley 40 .
- a sixth level of resistance is placed on knee support 32 by placing both flexible cables 44 on the highest pulley 40 .
- both flexible cables 44 are placed on pulleys 40 of a similar height so that a similar level of resistance is placed upon both sides of knee support 32 , as is shown in FIG. 2 .
- both flexible cables 44 exert the same amount of resistance on each side of knee support 32 , no torsional force is place on knee support 32 that would alter its direction of swing.
- a flexible cable 44 with a high degree of elasticity will produce a small amount of resistance on the motion of knee support 32 .
- a flexible cable 44 with a low degree of elasticity will produce a larger amount of resistance on the motion of knee support 32 .
- Frame 12 is shown in a fully extended open configuration. In this open configuration, hinges 18 are fully extended such that both hinge members 20 form a continuous linear member. The degree to which first frame 14 can pivot with respect to second frame 16 is restricted by hinges 18 .
- FIG. 3 illustrates a side view of abdominal exercise device 10 according to one or more embodiments of the invention.
- Pins 46 extend from the lower portions of frames 14 and 16 to allow for flexible cables 44 to connect to frame 12 .
- Flexible cables 44 connect to pins 46 by having the ends of flexible cables 44 formed into loops 48 that are then held by fasteners 50 .
- Knee pad 34 is preferably a rigid platform that is covered with a padded material so that the user may comfortably kneel upon knee pad 34 .
- knee pad 34 can be made of a rigid platform that is covered with a rigid or semi-rigid material that is contoured to provide an ergonomic surface for a user to kneel upon.
- Frame 12 is shown in an open configuration.
- a user would remove flexible cables 44 from frame 12 by uncoupling loops 48 from pins 46 .
- the user would then push the center of hinges 18 upward to displace the hinges 18 from their fully open configuration shown in FIG. 3 .
- the user would push first frame 14 towards second frame 16 , thereby minimizing the amount of space occupied by frame 12 , thereby enabling the usage of a smaller amount of storage space.

Description
- The present invention relates to the field of exercise equipment, and more in particular to an exercise device configured to provide an abdominal workout.
- In order to promote good health and physical well being, many individuals engage in physical exercise. It is common for individuals who are engaging in physical activities to employ the use of exercise devices to assist in performing exercises. Exercise devices that support individuals in the performance of exercises are common and exist in many varieties. One type of exercise device is an abdominal exercise device, which supports an individual in the performance of abdominal exercises.
- The abdominal muscles are a group of 6 muscles that extend from various places on the ribs to various places on the pelvis. They provide movement and support to the trunk, and are often called the core muscles. The most superficial abdominal muscle, the rectus abdominus, gives the “6-pack” ab effect when it is worked to a high degree of fitness. More structurally, the deeper and closer to the spine the particular abdominal muscle is, the more effect over body posture it will have, and this often contributes significantly to a healthy back.
- An abdominal exercise device is disclosed that includes a frame and a knee support configured to support both of a user's knees when the user is in a kneeled position. In one embodiment, the knee support is pivotally mounted to the frame, such that it swings with respect to the frame. A hand grip is attached to the frame. A user will kneel on the pivotally mounted knee support and grip the hand grip with their hands. By holding the hand grip, the user holds their upper body in a relatively stationary position with respect to the frame. Then, by contracting their abdominal muscles, the user can pivot the knee support upon which their knees rest up toward the support, thereby providing their abdominal muscles with a work out.
- The frame is made of two secondary frames that can be adjustably positioned with respect to each other. These two secondary frames can be positioned in an open or a closed position. In an open position, the frame is configured to allow the user to perform abdominal exercises. In these closed position, the frame is reconfigured to occupy less space so that it may be easily stored.
- The exercise device also includes a forearm support positioned adjacent to the hand grip. The forearm support provides a user with additional upper body support while the user contracts their abdominal muscles to pivot the knee support up toward the hand grip.
- The exercise device further includes a resistance enhancer that increases an amount of force required to pivot the knee support with respect to the frame. In one embodiment, the resistance enhancer is flexible cable that extends across the frame and engages the knee support.
- Other objects, features and aspects of the invention will become apparent from the following detailed description, the accompanying drawings, and the appended claims.
- The novel features that are considered characteristic of the invention are set forth with particularity in the appended claims.

FIG. 1 illustrates a rear perspective view of anabdominal exercise device 10 according to one or more embodiments of the invention.Abdominal exercise device 10 includes aframe 12.Frame 12 is formed of two secondary frames, afirst frame 14 and asecond frame 16.Secondary frames frame 12.Secondary frames Secondary frames frame 12.Frames Frame 12 is shown in an open position. When in an open position,frame 12 is configured to be utilized for abdominal exercises by a user.Frames frame 12. Whenframes frame 12 is in the closed position. In the closed position,frame 12 occupies a minimum of space, thereby making it easier to storeabdominal exercise device 10. -
Hinges 18 are located on each side offrame 12. Hinges 18attach frames frame 12. Further, hinges 18 limit the degree to which frames 14 and 16 can pivot with respect to each other.Hinges 18 are made of twomembers 20 that are pivotally joined toframes pins 22 and in the center ofhinge 18 bypin 24. -
Frames joints 26.Joints 26 join frames 14 and 16 together and enable them to pivot with respect to each other.Frames frames - An
upper body support 28 is attached tofirst frame 14.Upper body support 28 includes ahand support 29 and aforearm support 30, which individually and collectively form a torso support region.Upper body support 28 is also formed of shaped tubing. The tubing used forframes upper body support 28 can be formed of metal, plastic, a composite material, such as an epoxy coated carbon fiber material, or other structural material.Upper body support 28 may optionally be grasped by the user's arms or hands. In addition,upper body support 28 may optionally include a pad to support the forearms, chest and/or stomach or a user. - A
user support 32, also referred to as a knee support, is pivotally mounted toframe 12.User support 32 swings with respect to frame 12. As illustrated,frame 12 generally has an “A-frame” configuration, but can be of other configurations, such as a tripod, four legged support structure or other support structure that is able to pivotally supportuser support 32 for movement above the ground.User support 32 includes aknee pad 34, which is attached to athird frame 36.Third frame 36 is connected to pivotmounts 38 which are held into position by pins 39. In addition to pivotally mountingthird frame 36 to frame 12, pins 39couple joints 26 together to enableframes User support 32 generally has a “U” shape, but can have other configurations. For example,user support 32 may simply take the form of a sled provided with rollers that roll within an arcuate track mounted onframe 12. Or,user support 32 can simply be a sled that is supported on an arcuate track having rollers. All that is required foruser support 32 is some structure that can carry theknee pad 34 and enable arcuate movement of theknee pad 34. As used herein, the term “pivotal” movement should be broadly construed to encompass such arcuate movement, since such movement is typically about some axis of movement. - A user wishing to perform an abdominal exercise will kneel on
knee pad 34.Knee pad 34 is shown to have contours that conform to a user's two legs when they are positioned side by side.Knee pad 34 can be formed of a durable hard plastic that is contoured in the molding process. Alternatively,knee pad 34 may be formed of a rigid platform that is then covered with a spongy material, such as foam or other padding, along with a durable cover such as leather or a vinyl material. A contoured or padded surface increases the ergonomic utility ofknee pad 34. Specifically, as shown, a padded surface may be provided with a pair of spaced depressions or elongated channels for comfortably receiving the knees and/or shins of a user.Knee pad 34 is shown to comprise a single pad.Knee pad 34 can also comprise two separate pads (one for each knee and/or shin) that are operatively or structurally connected to enable them to move in unison. In one embodiment, theuser support 32 is constructed and arranged to carry all or substantially all of the user's body weight. In such an embodiment, theupper body support 28 is spaced away from the user's upper body so as to only provide a stabilizing mechanism when grasped by the user. In an alternative embodiment, theupper body support 28 is close to the user and can support some of the user's upper body weight. All that is required ofupper body support 28 is to enable the upper body of a user to be supported during arcuate movement ofknee pad 34. - Once the user is kneeling on
knee pad 34, the user graspshand support 29 and rests their forearms onforearm support 30. Together,hand support 29 andforearm support 30 provide the user with the ability to stabilize and hold their torso in a stationary position with respect to frame 12. Then, using their abdominal muscles, the user is able to pivot orswing knee support 32 up towardupper body support 28. The user is able to pivot orswing knee support 32 up towardupper body support 28 by contracting their abdominal muscles. By contracting their abdominal muscles to moveknee support 32, the user is performing abdominal exercises. - In use, a user's upper body can remain stationary while the user's lower body moves. The
abdominal exercise device 10 enables a user swing their lower body by contracting their abdominal muscles while holding their upper body in a relatively stable configuration that does not require the user to swing his head or neck around. - Attached to each side of
third frame 36 arepulleys 40 that are pivotally mounted tothird frame 36 by means ofpins 42. Aflexible cable 44 is attached bypins 46 at looped ends 48 toframes Flexible cable 44, together withpulleys 40, form a resistance enhancer, also referred to as a damper mechanism, that increases the force required for a user to pivot orswing knee support 32 up towardsupper body support 28. Loop ends 48 are formed inflexible cable 44 by means offasteners 50.Flexible cables 44 may be formed of elastic chords. A user can increase the amount of force required to pivot orswing knee support 32 up towardupper body support 28 by couplingflexible cable 44 to one of thepulleys 40. Twopulleys 40 are shown. Placingflexible cable 44 on theupper pulley 40 provides a higher degree of resistance than placing it on the lower pulley due to the fact thatflexible cable 44 is stretched more when placed on theupper pulley 40. For the least amount of resistance,flexible cable 44 is not attached to anypulley 40. It can thus be appreciated that an adjustable amount of damping can be applied to theuser support 32. The different pulleys 40 can thus be considered damping adjusters for purposes of this disclosure. Alternatively, the resistance enhancer or damper mechanism can also take the form of, just for example: (1) an adjustable friction device, for example at thepivot hinge 38 ofuser support 32 or at any region of theuser support 32 to generate friction damping; (2) a magnetic or electromagnetic damper mechanism as known in the exercise industry; (3) a friction belt and/or flywheel arrangement; or (4) a handle or lever to enable an exercise trainer or user to exert a dampening force manually onuser support 32. In each of these embodiments, damping adjusters may also optionally be provided to adjust the amount of friction, or magnetic damping force that is applied. -
FIG. 2 illustrates a perspective view of an abdominal exercise device according to one or more embodiments of the invention.Abdominal exercise device 10 is shown having a pair ofpulleys 40 and aflexible cable 44 on each side ofknee support 32. Eachflexible cable 44 provides a degree of resistance to the pivotal movement ofknee support 32. With twocables 44 each with twopulleys 40, there are six levels of resistance that can be supplied to theknee support 32. The first level of resistance is where neitherflexible cable 44 is placed on apulley 40, thereby placing no resistance onknee support 32. A second level of resistance is placed onknee support 32 by placing a singleflexible cable 44 on thelowest pulley 40. A third level of resistance is placed onknee support 32 by placing a singleflexible cable 44 on thehighest pulley 40. A fourth level of resistance is placed onknee support 32 by placing bothflexible cables 44 each on thelowest pulley 40. A fifth level of resistance is placed onknee support 32 by placing oneflexible cable 44 on thelowest pulley 40 and the otherflexible cable 44 on thehighest pulley 40. A sixth level of resistance is placed onknee support 32 by placing bothflexible cables 44 on thehighest pulley 40. - Note that it is possible to place both
flexible cables 44 onpulleys 40 of a similar height so that a similar level of resistance is placed upon both sides ofknee support 32, as is shown inFIG. 2 . When bothflexible cables 44 exert the same amount of resistance on each side ofknee support 32, no torsional force is place onknee support 32 that would alter its direction of swing. - It is possible to further alter the amount of resistance placed upon
knee support 32 by altering the strength offlexible cables 44. Aflexible cable 44 with a high degree of elasticity will produce a small amount of resistance on the motion ofknee support 32. Alternatively, aflexible cable 44 with a low degree of elasticity will produce a larger amount of resistance on the motion ofknee support 32. -
Frame 12 is shown in a fully extended open configuration. In this open configuration, hinges 18 are fully extended such that both hingemembers 20 form a continuous linear member. The degree to whichfirst frame 14 can pivot with respect tosecond frame 16 is restricted by hinges 18. -
FIG. 3 illustrates a side view ofabdominal exercise device 10 according to one or more embodiments of the invention.Pins 46 extend from the lower portions offrames flexible cables 44 to connect to frame 12.Flexible cables 44 connect topins 46 by having the ends offlexible cables 44 formed intoloops 48 that are then held byfasteners 50. -
Knee pad 34 is preferably a rigid platform that is covered with a padded material so that the user may comfortably kneel uponknee pad 34. Alternatively,knee pad 34 can be made of a rigid platform that is covered with a rigid or semi-rigid material that is contoured to provide an ergonomic surface for a user to kneel upon. -
Frame 12 is shown in an open configuration. To placeframe 12 into a closed configuration for storage of theabdominal exercise device 10, a user would removeflexible cables 44 fromframe 12 by uncouplingloops 48 from pins 46. The user would then push the center ofhinges 18 upward to displace thehinges 18 from their fully open configuration shown inFIG. 3 . Then, the user would pushfirst frame 14 towardssecond frame 16, thereby minimizing the amount of space occupied byframe 12, thereby enabling the usage of a smaller amount of storage space. -
