AUDIBLE REACTIVE TARGET

Abstract

Disclosed is a bullet target having a front bullet-resistant impact panel with at least one target aperture therein and a rear bullet-resistant impact panel having a portion aligned with the aperture such that a bullet passing through the aperture will strike the portion. The portion produces a first audible response upon impact of a bullet therewith and the first audible response is distinguishable from any other audible response produced by the front panel upon impact by another bullet. Also disclosed is a method of signifying impact of a bullet with one of the two target panels. A bullet projected through the aperture onto the second panel produces a first audible response and projecting another bullet onto the first panel produces a second audible response differing from said first audible response. A different score may be assigned to each of the first and second audible responses.

DETAILED DESCRIPTION

[0016] With reference to the drawing figures, this section describes particular embodiments and their detailed construction and operation. Throughout the specification, reference to “one embodiment,” “an embodiment,” or “some embodiments” means that a particular described feature, structure, or characteristic may be included in at least one embodiment. Thus, appearances of the phrases “in one embodiment,” “in an embodiment,” or “in some embodiments” in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the described features, structures, and characteristics may be combined in any suitable manner in one or more embodiments. In view of the disclosure herein, those skilled in the art will recognize that the various embodiments can be practiced without one or more of the specific details or with other methods, components, materials, or the like. In some instances, well-known structures, materials, or operations are not shown or not described in detail to avoid obscuring aspects of the embodiments.

[0017] Referring now to the drawing figures, therein is shown at 10 an audible reactive target according to one embodiment of the present invention. The target 10 includes a front panel 12 made of bullet-resistant, hardened steel and including one or more window of apertures 14,16 formed therein. Situated behind the front panel 12 is a rear harmonic panel 18 also made of bullet-resistant hardened steel and situated so that portions of the panel 18 are lined the apertures 14, 16 in the front panel 12. The panels 12,18 are supported in a spaced relationship so that the rear harmonic panel 18 can resonate when struck by a bullet. In preferred form, the rear harmonic panel 18 does not extend laterally beyond the profile of the front panel 12 so that a bullet impacting the rear panel 18 will by necessity have passed through one of the apertures 14, 16 in the front panel 12.

[0018] The front and rear panels 12, 18 may be independently supported or, as shown, the rear harmonic panel 18 may be supported by the front panel 12 in the illustrated embodiment, the front panel 12 is supported by an upright post 20 above the ground at a selected height. The rear harmonic panel 18, shaped and supported so that it will produce a resonant “ring” when struck by a bullet. This arrangement of the front and rear panels 12, 18 allows the target 10 to provide at least two distinct scoring zones. One scoring zone would be a bullet strike anywhere on the front surface of the front panel 12 and a second scoring zone would be an impact against the rear harmonic panel 18 of a bullet that has passed through one of the apertures 1, 16. Bullet strikes in either of the scoring zones produces an audible response that is distinct form that of the other scoring zone.

[0019] To enhance the distinction between the scoring zones, the rear harmonic panel 18 may be supported at harmonic node points so as to enhance the resonance vibration resulting from a bullet strike. Additionally, one or more tuning fork tines 22 may extend from the rear panel 18 to further enhance its resonance and/or to produce a resonant tone at one or more pre-selected frequencies.

[0020] The rear harmonic panel 18 may be supported by the front panel 12 at a spaced apart position, such as by carriage bolts 24 and nuts 26 with a heavy compression spring 28 acting as a spacer between the panels 12, 18. Amplitude or frequency of audible feedback provided by resonance of the rear panel 18 may be adjusted by tightening or loosening the nuts 26, thereby changing the compressive force of the springs 28.

[0021] The front panel 12 may be cut, for example, from ⅜ inch AR-500 hardened steel. The rear harmonic panel 18 may be made from quarter inch material of the same type, for example.

[0022] A cap 21 may be provided on the support post 20 to shield the top of the post 20 from bullet fragments.

[0023] Although the illustrated embodiment includes only one harmonic plate, it is possible to include multiple independent harmonic plates to represent different scoring zones. For example, the smaller scoring zone at the top of the target and the larger scoring zone at the bottom of the target could utilize two independent harmonic plates supported behind the front plate. The sound of each plate can be made distinct by changing the panel size, panel thickness, material type, connection location, spring size, compression, etc.

[0024] The target could also be designed so the first harmonic plate included a cutout scoring zone and a second harmonic plate (not shown) was mounted behind the first harmonic plate, creating a third scoring zone. In such an embodiment, it would be preferred that a bullet impact with the second harmonic plate produce a sound distinct from that of the first harmonic plate (and, of course, distinct from that of the front static plate).

[0025] Modifications to the compression springs represent one option for modifying the sound of the harmonic plate. Other options include changing the size and shape of the tuning forks, changing the material thickness of the plates, and modifying the mounting positions of the hardware. Optionally, the front panel can be damped to produce a contrasting “dead” sound or “plink” (rather than a “ring”), such as by placing connections at harmonic antinode locations and/or by adding material to it that interferes with resonant vibrations.

[0026] One alternate design utilizes a metal post (not shown) in place of the wood upright post. In this configuration, rubber vibration dampening mounts (not shown) can be used between the front static plate and the metal post. This helps reduce the vibration and sound generated when the outer static plate is struck, making it easier to distinguish between hits inside and outside the smaller scoring zones. Other designs could utilize a four-leg or tripod type base in place of the ground stake assembly.

[0027] In use, when a bullet passes through an aperture and strikes the harmonic plate, it produces an audible response that is distinct from that produced when a bullet strikes the front panel. A different score may be assigned to each of the first and second audible responses.

[0028] Advanced applications of this invention can utilize this target system in conjunction with a sound recognition and registering device. Sound recognition software can be programmed to distinguish between bullet strikes inside and outside the various scoring zones. Custom software can be programmed to include shot timers and specific courses of fire for competition shooting, personal training, law enforcement qualifications, and other shooting events. By use of a simple processor and microphone, such software can be used to automatically score the shooter's performance and display statistics regarding their accuracy and time through the course of fire.

[0029] Simple, inexpensive smart phone and tablet applications also can be programmed to perform these functions. The device's built in microphone can be used to record and recognize hits on different zones of the target and misses (a gunshot sound not followed by the sound of bullet impact with any zone of the target. The software can also store, track, and share shooting performance results.

[0030] Commercially available, off-the-shelf software is also available that is usable or adaptable to recognize the sound of the distinct target strikes. MyEarDroid™ (http://technalia.com) is an Android™ operating system application (app) which identifies specific sounds in the home environment and alerts an observer that the events that produced them have occurred by vibration and visual notifications. OtoSense™ (http://otosense.com) is an iPhone™/iPad™ (iOS operating system) application that will recognize a specific, preselected sound and translate it into a customizable visual alert. The app launches with a native library of general sounds, but the user can record unique sounds, in this case the sound of a projectile striking either panel of a target. The app can learn the pattern of a specific sound, a bullet strike, for example, and alert the user accordingly.

[0031] While one or more embodiments of the present invention have been described in detail, it should be apparent that modifications and variations thereto are possible, all of which fall within the true spirit and scope of the invention. Therefore, the foregoing is intended only to be illustrative of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not intended to limit the invention to the exact construction and operation shown and described. Accordingly, all suitable modifications and equivalents may be included and considered to fall within the scope of the invention, defined by the following claim or claims.
