The present invention relates generally to decelerating projectiles and more particularly, to a bullet trap apparatus, which includes increased bullet deceleration with an angled back plate.
In the past, bullet trapping systems were bulky and hard to set up in the field. Many were not portable and therefore could not be easily moved from location to location as may be desired. Some bullet trap systems use rubber grains and rubber nuggets. However, these types of medium have some disadvantages in their ability to efficiently capture a bullet therein and, further, they experience some severe degradation during extended use.
It is therefore desirable to have a portable bullet trap apparatus and a flowable bullet trap medium, which efficiently captures projectiles such as bullets and which can efficiently capture the projectiles such as bullets for extended periods of use without the need to frequently replace the medium. U.S. Pat. No. 8,550,466 to Priebe et al. discloses a bullet decelerating medium and bullet trapping system and method using the medium. However, the Priebe patent does not teach or suggest an angled back plate for reducing the deceleration of a bullet fired into the bullet trapping system. Priebe et al. is hereby incorporated by reference in its entirety into this application.
Accordingly, there is a clearly felt need in the art for a bullet trapping apparatus, which includes increased bullet deceleration with an angled back plate.
The present invention provides a bullet trapping apparatus, which includes increased bullet deceleration with an angled back plate. The bullet trap apparatus preferably includes a housing, a support structure and energy absorbing material. The housing preferably includes a bullet guiding collar, a front energy absorbing panel, a front wall plate, a four sided box, an angled back plate and an angled armor plate. The bullet guiding collar preferably includes a base plate, a four-sided peripheral wall and a four-sided angled flange. The base plate includes a rectangular base opening. The four-sided peripheral wall is preferably perpendicular to the base plate and is attached thereto. The four-sided angled flange is attached to the base plate and the four-sided peripheral wall. The front energy absorbing panel is preferably fabricated from a either a screen or a fabric layer laminated to a front of a rubber material. The front wall plate includes a rectangular opening formed therethrough. The four sided box includes a top plate, a bottom plate, a first side plate and a second side plate. The top, bottom, first side and second side plates are attached to each other to form the four-sided box. The top and bottom plates include a pentagon shape. The front wall plate is attached to a front of the four-sided box. The front energy absorbing panel is located between the base plate of the bullet guiding collar and the front wall plate.
The angled back plate includes a first angled back plate and a second angled back plate. Adjacent edges of the first and second angled back plate are joined to each other. A perimeter of the angled back plate is attached to a perimeter of a rear of the four-sided box. Preferably, four armor spacers are attached in four corners of the angled back plate. A rear of the angled armor plate is glued to the four armor spacers. A top edge of the bullet guiding collar is preferably hinged to a top of the four-sided box, such that a space is created for the insertion of the front energy absorbing panel. A bottom edge of the bullet guiding collar is bolted to a bottom bracket on a bottom edge of the four-sided box. The housing is filled with the energy absorbing material. The energy absorbing material is preferably granulated rubber, but other materials may also be used.
The support structure preferably includes a first side leg, a second side leg, a rear leg base plate, a side reinforcement plate, a first side leg base plate and a second side leg base plate. The first leg includes a first side leg and a first rear leg. The first rear leg extends from the first side leg. The second leg includes a second side leg and a second rear leg. The second rear leg extends from the second side leg. A first end of the side reinforcement plate is attached to the first side leg and a second end of the reinforcement plate is attached to the second side leg. The first side leg is preferably bolted to the first side plate. The second side leg is preferably bolted to the second side plate. A bottom of the first side leg is attached to the first side leg base plate and a bottom of the second side leg is attached to the second side leg base plate. The rear leg base plate includes a first leg projection and a second leg projection. A bottom of the first rear leg is preferably bolted to the first leg projection and a bottom of the second rear leg is preferably bolted to the second leg projection. The support structure acts as a tripod to support the housing.

These and additional objects, advantages, features and benefits of the present invention will become apparent from the following specification.
With reference now to the drawings, and particularly to
The four sided box 22 includes a top plate 44, a bottom plate 46, a first side plate 48 and a second side plate 50. Edges of the top, bottom, first side and second side plates 44, 46, 48, 50 are attached to each other to form the four-sided box 22 with welding or any suitable attachment method. The front wall plate 20 is attached to a front of the four-sided box 22. The front energy absorbing panel 18 is located between the base plate 30 of the bullet guiding collar 16 and the front wall plate 20. The angled back plate 24 includes a first angled back plate 52 and a second angled back plate 54. The top and bottom plates 44, 46 include a pentagon shape to cover angled back plate 24. Adjacent edges of the first and second angled back plates 52, 54 are joined to each other with welding or any suitable attachment method. A perimeter of the angled back plate 24 is attached to a perimeter of a rear of the four-sided box with welding or any suitable attachment method.
Preferably, the four armor spacers 28 are attached in four corners of the back plate 24. The angled armor plate 26 includes a first armor plate 55 and a second armor plate 57. The first and second armor plates 55, 57 are preferably fabricated from AR-500 hardened armor plate. Alternatively, the angled armor plate 26 could be substituted for the angled back plate 24. Adjacent edges of the first and second angled armor plates 55, 57 are joined to each other with welding or any suitable attachment method. The most preferable value of an included angle “A” between the first and second armor plates 55, 57 is an obtuse angle of 120 degrees. The 120 degree angle of the angled armor plate 26 prevents the projectile from ricocheting back at a shooting source of the projectile. A second preferable value of angle “A” is between 115-125 degrees. However, angle “A” may also have other values. A rear of the angled armor plate 26 is glued to the four armor spacers 28. The four armor spacers 28 are preferably fabricated from a resilient material, such as rubber. A top edge of the bullet guiding collar 16 is preferably hinged to a top of the four-sided box 22 with a pair of hinges 56 or the like, such that a space is created for the insertion of the front energy absorbing panel 18. A bottom edge of the bullet guiding collar 16 is bolted to a bottom bracket 58 on a bottom edge of the four-sided box 22. The housing 10 is filled with the energy absorbing material 14 to decelerate motion of a projectile fired into the housing 10. The energy absorbing material 14 is preferably granulated rubber, but other materials may also be used. The energy absorbing material 14 is preferably sufficient to stop the motion of a projectile. The armor plate 18
In use, a projectile fired into the bullet trapping apparatus 1 will pass through the front energy absorbing panel 18; into the energy absorbing material 14 and stop within the energy absorbing material 14. However as a fail safe for a projectile, which has too much power, the projectile will hit at least one of the first and second plates of the angled back plate 24 or the angled armor plate 26; and come to a stop.
