Abstract

A simulation munition of a bean bag crowd control round is provided. The simulation munition includes a cartridge with first and second bores disposed therein; a muzzle loading primer insertable into the second bore at the second opening to the cartridge wherein any explosive force created by the primer will be directed toward the first opening; a shotgun wad insertable into the first bore through the first opening until the wad positions adjacent the second bore; and a reball insertable into the shotgun wad. When the munition is assembled, the shotgun wad is located adjacent the second bore, the reball is located in the shotgun wad and the muzzle loading primer is located in the second bore of the cartridge. The munition is configured to fire the reball from an explosive force caused by the muzzle loading primer that moves the reball with a less than lethal force.

Description

RELATED APPLICATIONS

The present application is related to and claims priority to U.S. Provisional Patent Application Ser. No. 61/239,284, filed on Sep. 2, 2009, entitled “Practice Munitions.” The subject matter disclosed in that provisional application is hereby expressly incorporated into the present application.

TECHNICAL FIELD AND SUMMARY

The present disclosure is related to practice munitions for firearms and, in particular, low cost and reusable less-than-lethal munitions to simulate bean bag cartridges and shotgun rounds.
As new law enforcement tools become available to quell unrest using non-lethal firearms, so too does their need to practice with those firearms. In certain circumstances, lethal guns and bullets have been replaced with non-lethal bean bag launchers. These launchers look like oversized single barrel shotguns typically accommodating 37 to 40 millimeter shells. Beanbag cartridges are packed with what looks like socks filled with rubber pellets, sand and other materials. When a bean bag projectile hits an individual, kinetic energy transfers to the point of impact causing pain but not lethal injuries.
Despite the substantial benefit, each bean bag cartridge is relatively expensive when compared to a bullet. Practice rounds which do not fire bean bags are also expensive. In 2009 dollars, a bean bag practice round costs about $25.00. Training is a critical component of effective law enforcement, but spending $25.00 every time the launcher is fired can create havoc on a training budget.
One embodiment of the present disclosure describes a 37/40 millimeter bean bag simulation munition for a 37/40 millimeter launcher, but costs literally pennies on the dollar compared to a conventional 37/40 millimeter bean bag simulation munition.
As described further herein, an embodiment of this disclosure includes a 37 or 40 millimeter specially made cartridge that fits into a conventional 37 or 40 millimeter riot shotgun. Inside the cartridge, however, is a muzzle loading primer held by an in-line muzzle loading primer holder. An illustrative 12 gauge shotgun wad is also contained in the cartridge to hold a reball or soft projectile substitute to be fired. The cartridge is configured to allow its reloading in the field with these components which are easily attainable and relatively inexpensive. In addition, the holder, wad, and reball are all reusable, making the cost per shot even less.
Another illustrative embodiment of the present disclosure provides a simulation munition of a bean bag crowd control round. The simulation munition comprises a cartridge, a muzzle loading primer, a shotgun wad, and a reball. The cartridge includes first and second bores disposed therein. The first and second bores are coaxially aligned, the first bore has a greater diameter than the diameter of the second bore, and the first bore terminates at a first opening that is opposite on the cartridge from a second opening that terminates the second bore. The muzzle loading primer is insertable into the second bore at the second opening to the cartridge, wherein any explosive force created by the primer will be directed toward the first opening. The shotgun wad is insertable into the first bore through the first opening until the wad positions adjacent the second bore. The reball is insertable into the shotgun wad. When the munition is assembled, the shotgun wad is located adjacent the second bore, the reball is located in the shotgun wad and the muzzle loading primer is located in the second bore of the cartridge. The munition is configured to fire the reball from an explosive force caused by the muzzle loading primer that moves the reball with a less than lethal force.
In the above and alternative embodiments, the simulation munition may further comprise: the cartridge being sized to fit in a launcher gun; the cartridge being sized to fit in an oversized single-barrel shotgun that accommodates 37 to 40 millimeter shells; the reball being configured in the cartridge such that when fired it will impact a target similar to a beanbag; the shotgun wad being a 12-guage shotgun wad; the cartridge, wad, and reball are all reusable; the cartridge being made of an aluminum material; the cartridge being made of an polymer material; the cartridge being configured to receive a previously used wad and reball, and a new primer to be ready for refiring.
Another illustrative embodiment of the present disclosure includes a method of making a simulation munition of a bean bag crowd control round. The method of making simulation munition comprises the steps of: providing a cartridge having first and second bores disposed therein, where the first and second bores are coaxially aligned, the first bore has a greater diameter than the diameter of the second bore, and the first bore terminates at a first opening that is opposite on the cartridge from a second opening that terminates the second bore; inserting a muzzle loading primer into the second bore at the second opening to the cartridge, wherein any explosive force created by the primer will be directed toward the first opening; inserting a shotgun wad into the first bore through the first opening until the wad positions adjacent the second bore; and inserting a single reball into the shotgun wad such that when the shotgun wad is located adjacent the second bore, the reball is located in the shotgun wad and the muzzle loading primer is located in the second bore of the cartridge, the munition is made.
Additional features and advantages of the simulation munition will become apparent to those skilled in the art upon consideration of the following detailed description of the illustrated embodiment exemplifying the best mode of carrying out the simulation munition as presently perceived.

DETAILED DESCRIPTION OF THE DRAWINGS

A perspective view of a law enforcement training simulation is shown in FIG. 1. In this simulation, actor 2 depicts an aggressor and actor 4 is tasked with repelling actor 2 using a bean bag launcher 6. Actor 4 can train with bean bag launcher 6, even firing it at actor 2 without causing lethal bodily injury. In an illustrative embodiment, bean bag launcher 6 fires a reball which is a rubber or a soft plastic ball that simulates a paintball sans rupturing on impact.
A perspective view of bean bag launcher 6 in the loading position with a simulation munition 8 partially inserted into its bore is shown in FIG. 2. Also shown in this view is a separate empty simulation cartridge 10, muzzle loading primers 12, shotgun wads 16, and reballs 18. Items 12-16 can be used to reload and reuse cartridge 10. Keeping in mind that a conventional practice round costs about $25.00, the reusable components make each shot cost about $0.75 after the initial purchase of the cartridge in 2009 dollars.
A perspective view of bean bag launcher 6 unlatched with simulation munition 8 inserted into bore 20 is shown in FIG. 3. In this illustrative embodiment, munition 8 is configured to fit into 37 and 40 millimeter bores. Accordingly, loading and unloading simulation munition 8 is essentially the same experience as loading and unloading a live bean bag round.
A side cutaway view of simulation munition 8 is shown in FIG. 4. Cartridge 10 is cut away revealing bore 22 with opening 24 that receives and expels reball 18. Once loaded and prepared for firing, it is appreciated that reball 18 is positioned inside wad 16. At the other end of bore 22 is narrow opening 26. This narrow opening 26 communicates bore 22 with primer cavity 28 and is sized and configured to receive primer 12. Opposite narrow opening 26 is holder opening 30 that receives primer 12 which fits into cavity 28. When the gun powder in muzzle loading primer 12 ignites, the force of the explosion projects towards narrow opening 26 propelling reball 18 out of bore 22 through opening 24.
Another side cutaway view of simulation munition 8 is shown in FIG. 5. This view is similar to the exploded view in FIG. 4 except with stem 14 of a muzzle loading ball starter 40 inserted into bore 22. Stem 14 pushes ball 18 into wad 16. In addition, primer 12 is inserted into opening 30 and fitted within cavity 28. In this position, primer 12 is pushed up adjacent narrow opening 26. Wad 16 is fitted into bore 22 adjacent narrow opening 26. In this illustrative embodiment, a space 32 accommodates the expansive force of the ignited gun powder from primer 12. Reball 18 is held inside cup portion 34 of wad 16. This view also shows flange 36 extending from outer wall 38 of cartridge 10 similar to a conventional 40 millimeter live or simulated round. Flange 36 assists keeping cartridge 10 inside the bore of the launcher while reball 18 is firing. Cartridge 10 is also a reusable component that may be assembled into munition 8 over and over again with either these several aforementioned components and/or other components.
Part of the cost saving feature of simulation munition 8 is that the end user, particularly law enforcement personnel, can purchase many of the components at various retail firearm departments or stores. This makes obtaining the components needed to assemble the munition easily attainable, as well as relatively inexpensive.
Various views of muzzle loading primer 12 are shown in FIG. 6. Muzzle loading primer 12 contains the amount of gun powder needed to create the explosion that propels reball 18 from the gun with a less-than-lethal force. Illustratively these are conventional muzzle loading primers, such as the KLEANBORE Primers made by Remington Arms Company, Inc., Madison, N.C.
Perspective views of a plurality of cartridges 10 are shown in FIG. 7. These cartridges can be made from aircraft grade aluminum, plastic, [IDENTIFY OTHER MATERIALS] and have an exterior size similar to that of a live cartridge. This allows the same gun used in live tactical situations to also be used on the practice range.
Shotgun wad 16, as shown in FIG. 8, is useful for holding reball 18, as well as fitting inside cartridge 10. Furthermore, wad 16 is commercially available and is inexpensive, thus helping lessen the cost of firing the simulated round. Reball 18, as shown in FIG. 9, is similar in shape and configuration to a conventional paintball, but is a rubber ball that does not rupture on impact. It can, therefore, withstand the force created by muzzle loading primer 12 when propelling out of launcher 6.
Again, an advantage of simulation munition 8, besides being effective and affordable, is that cartridge 10 can also be easily reloaded in the field to fire a new round. In this illustrative embodiment, FIGS. 10-15 demonstrate an illustrative method of reloading cartridge 10 to make a new simulation munition 8.
As shown in FIG. 10, the first step is seating primer 12. In this illustrative embodiment, muzzle loading ball starter 40 may be used to push primer 12 into opening 30 and seat in cavity 28 of cartridge 10. Sometimes it is possible to seat the primer using fingertip pressure, but in this example the muzzle loading ball starter 40 is used.
The view shown in FIG. 11 includes seating reball 18 into cup portion 34 of shotgun wad 16. After reball 18 has been seated, it and wad 16 are inserted together into opening 24 of cartridge 10, as shown in FIG. 12. In order to get wad 16 and ball 18 further down into bore 22, as shown in FIG. 5, stem 14 of muzzle loading ball starter press 40 is inserted into bore 22 pushing reball 18 and wad 16 further down inside, as shown in FIG. 13. In the illustrative embodiment, the reball and wad is pushed as far down as they can go. At this point, simulation munition 8 is fully assembled and ready to be loaded into launcher 6.
After munition 8 is fired, cartridge 10 can be removed from launcher 6 and reassembled into another working munition. The view shown in FIGS. 14 and 15 depict an illustrative method of preparing cartridge 10 to be reassembled into munition 8. The first step is to remove the spent primer 12 by inserting a primer removal tool 50 into bore 22. Tool 50 is configured to push primer 12 out from opening 30. As shown in FIG. 14, by pushing on tool 50 in direction 52, primer 12 will be pushed out of cartridge 10 in direction 52 as well.
A side cross-sectional view of munition 8 with tool 50 inserted therein is shown in FIG. 15. This view demonstrates how tool 54 would lose primer 12. As shown, tool 50 includes rod 54 with a pin 56 extending therefrom. Pin 56 is configured to insert into bore 28 and engage primer 12. Pin 56 is long enough so that by pushing tool 50 in direction 52, pin 56 engages primer 12 and pushes it out of opening 30.
A side view of tool 50 is shown in FIG. 16. In this illustrative embodiment, tool 50 includes a handle portion 58 that attaches to rod 54 and pin 56. In one illustrative embodiment, the diameter of rod 54 may be slightly less than the diameter of bore 22, so that when rod 54 is inserted therein, it automatically aligns pin 56 with bore 28 in cartridge 10 to push primer 12, as shown in FIG. 15. In addition, the lengths of both rod 54 and pin 56 extend far enough to accomplish the removal process.
Although the present disclosure has been described with reference to particular means, materials and embodiments, from the foregoing description, one skilled in the art can easily ascertain the essential characteristics of the present disclosure and various changes and modifications may be made to adapt the various uses and characteristics without departing from the spirit and scope of the present invention as set forth in the following claims.
