## Background
BACKGROUND
(1) Field of the Disclosure
This disclosure relates to shooting ranges of the kind including a projectile trap and a projectile trap for varied uses, including for use in a shooting range.
(2) Description of 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.
One such prior art dry system apparatus produces a negative air pressure within the trap, but this has proven unsatisfactory because the negative air pressure may unnecessarily pull lead from the trap that would otherwise be removed by a collection system at the bottom of the trap. Thus, this kind of system may actually increase, rather than reduce, contamination problems resulting from lead and other metals. Also creating the negative air pressure system is energy consumptive due to the high volume of air flow needed. Thus, this kind of prior art projectile trap leaves much to be desired.

DESCRIPTION OF VARIOUS EMBODIMENTS
In the following description, like reference characters designate like or corresponding parts throughout the several views. Also in the following description, terms such as “forward,” “left,” and “downwardly,” are words of convenience and are not limiting terms. The illustrations provided are for describing embodiments of a shooting range and do not limit the range to any particular embodiment shown or described.
FIG. 1 shows an embodiment of a shooting range, generally designated 10, constructed according to the present inventions. The shooting range 10 includes a safety area 28 where firearms may be inspected and readied. In addition, range management may have offices adjacent or in the safety area 28. Limited access to the shooting range 10 may be provided by additional fencing and supplemented, in part, by a containment system, generally designated 54.
FIG. 2 is a cross-sectional view of a portion of shooting range 10. FIG. 2 shows a shooting station 12, a projectile trap 14 and at least one range auxiliary system that may include: a targeting system 52; a containment system 54 that may optionally include one or more sidewalls, such as the wall 60, overhead baffles 56, and or a safety ceiling 59; or a heating ventilation air conditioning (HVAC) system 62 and combinations thereof. The shooting station 12 may include one or more of a firing position 18 and a shooting booth 20 that may optionally include a weapon rest 24 and or a lane divider 22.
FIG. 3 shows a projectile trap 14 including a trap chamber 30, an air injection system 32 positioned upstream, in reference to the direction of projectile travel, of the trap chamber 30, and an air collection system 34 downstream of the injection system 32 that may optionally include an air filter 50. In an embodiment of the projectile trap 14, the chamber 30 includes an inlet 33 and an inner curved surface 36 for receiving a projectile and reducing its velocity through contact with the surface 36. The injection system 32 shown may include an air supply 38, air inlets, such as the inlet 42, which is shaped as a slot and oriented toward the chamber 30, and air outlets, such as the outlet 40, which is also shaped as a slot and is also oriented towards the chamber 30. The collection system 34 may optionally include an exhaust fan 44 having an operating CFM equal to or greater than that of an injection fan 46 to aid in controlling the direction and velocity of the air from the air injection system.
In embodiments, 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.
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 a impact plate design. Also, the location of the air outlets and inlets can be modified. For instance, while the inlet and outlet is shown above the inlet to the chamber in FIG. 3, one or both of them can be located below the inlet, or an inlet and outlet may be below corresponding, respectively, to an outlet and inlet above in order to provide some cross-flow across the inlet of the projectile trap. Also, in some applications it may be practical to induct air from a sidewall adjacent to the projectile trap, rather than from above the chamber inlet. 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.
