(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.
This disclosure is directed to a shooting range including a shooting station and a projectile trap. In an embodiment, the shooting range includes one or more range auxiliary systems. Also, in an embodiment, the projectile trap includes a trap chamber, an air injection system and an air collection system.
Accordingly, an embodiment of the range provides at least one shooting station and at least one projectile trap having a trap chamber and an air injection system positioned upstream of the trap chamber.
An embodiment of the projectile trap includes a trap chamber, an air injection system positioned upstream of the trap chamber 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, where ‘upstream’ and ‘downstream’ refer to the direction of projectile travel.
Other embodiments of the range include at least one shooting station, at least one projectile trap and at least one range auxiliary system. The projectile trap includes: a trap chamber; an air injection system positioned upstream of the trap chamber; 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.
In certain embodiments, the trap further includes a trap guide and the air injection system is adjacent to the trap guide and includes one or more outlets in the form of a slot oriented toward the chamber. Also, the collection system is downstream of the injection system and upstream of the chamber and may also include one or more air inlets in the form of a slot oriented toward the chamber. In addition, the collection system may have an operating CFM equal to or greater than that of the injection system. Moreover, the trap guide may be a pair of opposed ramps, each ramp optionally having an angle between about 5° and 25° from horizontal. Furthermore, in embodiments of the apparatus, the chamber may be a deceleration chamber including an inlet and an inner curved surface for receiving and reducing the velocity of a projectile.
Accordingly, one aspect of the disclosure is to provide a shooting range including at least one shooting station and at least one projectile trap having a trap chamber and an air injection system positioned upstream of the trap chamber.
Another aspect of the disclosure is to provide a projectile trap including a trap chamber, an air injection system positioned upstream of the trap chamber, 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.
Yet another aspect is to provide a shooting range including: at least one shooting station; at least one projectile trap having (a) a trap chamber; (b) an air injection system positioned upstream of the trap chamber; and (c) 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; and at least one range auxiliary system.
These and other embodiments of the apparatuses will become apparent to those skilled in the art after a reading of the following description of the embodiments when considered with the drawings.
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.
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
