(1) Field of the Invention
The present invention relates generally to shooting ranges of the kind including a projectile trap and, more particularly, to a projectile trap for varied uses, including for use in a shooting range.
(2) Description of the Prior Art
The design and operation of shooting ranges is a sophisticated engineering matter in which safety is paramount. Thorough discussions of the design and layout of modern shooting ranges may be found in “Design Criteria for Shooting Ranges” by C. Vargas, Third National Shooting Range Symposium (1996); Army Regulation AR 385-63 “Range Safety”; Navy Handbook (MIL-HDBK) 1027/3B, “Range Facilities and Miscellaneous Training Facilities Other Than Buildings” and the National Rifle Association's “NRA Range Source Book.” These references are hereby incorporated by reference in their entirety.
Shooting ranges having projectile traps are known. Heretofore, the traps have included various apparatuses for preventing fragments of lead and other metals from escaping the traps and becoming a hazard to health and the environment. Both liquid and dry systems are popular. Examples of such systems, commonly owned by the applicant, are described in U.S. Pat. Nos. 5,070,763, 5,113,700, 5,121,671 and 5,486,008 issued to Coburn.
The construction of a shooting range with a projectile trap may be accomplished by joining individual subassembly deceleration chambers. These assemblies are generally cylindrical in shape with endplates provided for joining each deceleration chamber to an additional adjacent deceleration chamber until the desired width of projectile trap is accomplished. These cylindrical shaped deceleration chambers may leave the endplate exposed to projectile impact and visible from the shooter's perspective. This edge could be impacted by an inline projectile while the edge also may restrict horizontal cross firing, and the edge was at all times visible to the shooter.
U.S. patent application Ser. Nos. 10/317,025 filed Dec. 11, 2002 (Publication No. 2003/0177895); 11/437,469 filed May 19, 2006 (Publication No. 2006/0208425); and 11/437,231 filed May 19, 2006 (Publication No. 2006/0220319), to Lambert disclose a shooting range including a projectile trap without intervening sidewalls where the deceleration chamber is formed by a multitude of individual plates. This shooting range has not been generally accepted because of high manufacturing costs associated with fixing large numbers of individual plates to adjoining plates.
Thus, there remains a need for a new and improved shooting range having at least one shooting station and at least two projectile traps adapted to be joined together along adjacent ends in a manner which provides for substantially unobstructed horizontal cross firing while, at the same time, the front edges of the joint between the projectile traps are substantially out of view from the shooting station.
The present inventions are directed to a shooting range including at least one shooting station and a projectile trap. The projectile trap includes at least two projectile trap subassemblies each having at least one end plate and joined together along adjacent end plates and a trap chamber in each of the projectile trap subassemblies, wherein a portion of the front edge of the joint between the projectile trap subassemblies is transposed into the trap chambers substantially out of view from the shooting station. In a preferred embodiment, the shooting range further includes at least one range auxiliary system.
In a preferred embodiment, the transposed portion of the front edge of the joint between the projectile trap subassemblies is about 90° downstream from the entrance to said trap chamber. The transposed portion of the front edge of the joint between the projectile trap subassemblies may be the portion of the front of the projectile trap subassemblies not protected by the trap guide.
Also, the present inventions may, further include a trap guide for directing a projectile into the trap chambers and protecting the front edge of said projectile trap subassemblies. The trap guide may include at least one pair of opposed ramps. In a preferred embodiment, the angle of each ramp is between about 5° and 25° from horizontal.
In a preferred embodiment, the end plates are joined together by at least one fastener assembly. A seam protector attached to the intersection of the exposed and displaced seam surface between adjacent end plates may also be included. The seam protector may be an overlapping abrasion resistant plate.
In a preferred embodiment, the trap chamber is a deceleration chamber. The deceleration chamber may further include an inlet and inner curved surface for receiving the projectile wherein the velocity of the projectile is reduced by contact with the inner surface. The deceleration chamber may further include an exit for decelerated projectiles. An embodiment of the trap chamber may further including a projectile retrieval system. In addition, the projectile trap may include at least one secondary support to support the projectile trap.
In certain embodiments, the projectile trap further includes an air injection system and an air collection system positioned downstream of the air injection system for receiving at least a portion of the air from the air injection system. The air injection system includes an air supply and at least one air outlet, where the air outlet may include a plurality of spaced apart air outlets, whereby the plurality of spaced apart air outlets are slots. At least one of these air outlets is oriented towards the trap chamber. The air collection system includes at least one air inlet, where at least one air inlet includes a plurality of spaced apart air inlets, whereby the plurality of spaced apart air inlets are slots. At least one air inlet is oriented towards the trap chamber. The air collection system also includes at least one exhaust fan and may include at least one air filter. In addition, the operating CFM of the air collection system is greater than or equal to the operating CFM of the air injection system.
In an embodiment, the shooting range may include a range auxiliary system, the range auxiliary system possibly being a targeting system, a containment system that may contain side walls, a safety ceiling and overhead baffles, and/or an HVAC system. Furthermore, the shooting range may also include a firing position, or may include a shooting booth, or possibly include a weapon rest and/or at least one lane divider.
Accordingly, one aspect of the present invention is to provide a shooting range including: (a) at least one shooting station; and (b) at least two projectile traps joined together along adjacent ends wherein the front edge of the joint between the projectile traps includes a backwardly transposed portion substantially out of view from the shooting station
Another aspect of the present invention is to provide an improved projectile trap for a shooting range having at least one shooting station including: (a) at least two projectile trap subassemblies each having at least one end plate and joined together along adjacent end plates; and (b) a trap chamber in each of the projectile trap subassemblies, wherein a portion of the front edge of the joint between the projectile trap subassemblies is transposed into the trap chambers substantially out of view from the shooting station.
Still another aspect of the present invention is to provide a shooting range including: (a) at least one shooting station; (b) a projectile trap including (i) at least two projectile trap subassemblies each having at least one end plate and joined together along adjacent end plates and (ii) a trap chamber in each of the projectile trap subassemblies, wherein a portion of the front edge of the joint between the projectile trap subassemblies is transposed into the trap chambers substantially out of view from the shooting station; and (c) at least one range auxiliary system.
These and other aspects of the present invention will become apparent to those skilled in the art after a reading of the following description of the preferred embodiment when considered with the drawings.
a is an enlarged rear perspective view of a series of trap assemblies as seen in
b is an enlarged front perspective view of a series of trap assemblies as seen in
c is an enlarged front perspective cutaway view a trap assembly as seen in
In the following description, like reference characters designate like or corresponding parts throughout the several views. Also in the following description, it is to be understood that such terms as “forward,” “rearward,” “left,” “right,” “upwardly,” “downwardly,” and the like are words of convenience and are not to be construed as limiting terms.
Referring now to the drawings in general and
a, 10b and 10c illustrate cut-away views of the projectile traps 14, with elements of the trap guide 26 and the projectile traps 14 shown in phantom.
In one embodiment, the projectile trap 14 may also include a trap guide 26 wherein the injection system 32 is adjacent the guide 26 and the collection system 34 is upstream of the chamber 30. The guide 26 may be a pair of opposed ramps 27 and 29 with each ramp having an angle between about 5° and 25° from horizontal. In addition, the trap chamber may further include an exit 70 for decelerated projectiles. In an alternative embodiment, the trap may further include a projectile retrieval system 72 for disposing of fired projectiles. The projectile trap may further include a seam protector 64.
Certain modifications and improvements may occur to those skilled in the art upon a reading of the foregoing description. By way of example, while the shooting range shown includes a circular projectile deceleration chamber, other types of traps could be used, including, without limitation, the kind having an impact plate design. It should also be apparent that any rounded shape could be used as a projectile trap and the invention is not limited to just circular one sided shapes. Also, the deceleration chamber could be made from a series of plates having flat faces, such as shown in U.S. Pat. No. 5,811,718, issued to Bateman. Also, while an air injection system is shown, the present inventions could also be used with wet injection systems previously discussed above. All such modifications and improvements have not been included herein for the sake of conciseness and readability but may properly fall within the scope of the appended claims.
This application is a continuation of application Ser. No. 11/733,474 filed Apr. 10, 2007, now abandoned.
