This invention relates principally to projectile targets constructed with self-healing polymers, and more particularly to a self-healing shooting target that produces an audible and kinetic response when struck by a bullet slug or other projectile, and which captures the slug to minimize the chance of ricochet.
What is commonly known in the firearms industry as a “self-healing” target is a target that is constructed with a an elastic polymer that can be penetrated by a bullet slug and then due to the plasticity of the polymer, the target will reform to its original shape after such penetration. That is, a bullet hole in the target will close or “self-heal” on its own without aid or assistance. This is due to the particular polymers used in the construction of the target. As the bullet slug passes through the polymeric material, the friction and heat created by the slug is absorbed by the material surrounding the penetration path. The polymeric material reacts by contracting and closing the path through the material. Further, these features of “self-healing” targets also substantially slow, or even stop, the progress of a bullet slug passing through the polymer. Although self-healing targets can vary considerably in size, shape, material type, each may be able to absorb thousands of strikes before serious degradation requires replacement.
Further, competition shooters sometimes fire at their target at close range in a rapid movement, which exposes the shooter to ricochets if a steel target is being used. The self-healing polymer targets are soft enough to minimize the chance that a bullet slug will ricochet and endanger the shooter when firing at close range. Thus, self-healing targets provide the opportunity for close-in target practice.
For these reasons, self-healing targets have recently gained popularity in the sporting market. Such self-healing targets are marketed in a wide variety of target constructs, including for example, “gong” (i.e., audible) and spinning (i.e., kinetic) targets. It is not uncommon for self-healing targets to be designed with the polymeric material layered over or forming a coating on top of a rigid material, such as for example wood, rigid plastic, or a metal such as steel. This enables the target to form and retain a desired shape while still providing the benefits of the target's self-healing polymers.
However, traditional steel-backed targets do not allow the bullet slug to pass through the self-healing target. Rather, the bullet slug will likely get stuck in the target. A bullet slug stuck in the target held in place by the polymer can cause a ricochet if struck by another projectile, endangering or injured the shooter.
In addition, the kinetic energy from a bullet slug impacting a traditional self-healing” polymer target can be absorbed by the target in such a way that the target will not display a visual movement to indicate the strike. Also, the sound of the bullet slug hitting a traditional “self-healing” polymer target can be drowned out by the firing/discharging of the firearm. This condition can be complicated in certain forms of multi-target competition shooting, for example when competition shooters fire very fast and look to a visual movement of the target, as opposed to a sound response, to cue the shooter to move to the next target.
Further, self-healing polymers act as sound dampening agents. As a consequence, the polymers will produce little, if any, sound when struck by a bullet slug. Moreover, even when the targets are constructed with rigid materials that would otherwise generate an audible response when struck by a bullet slug, the polymers coating the rigid materials muffle or entirely eliminate any such sound from being generated by the target. Moreover, self-healing targets that comprise a polymer over a rigid backing, such as steel, may still result in a ricocheted slug when struck.
Because an audible response is a very desirable feature of shooting targets, it would therefore be desirable to have a kinetic self-healing target that is capable of producing an audible response that can be readily heard by a user shooting at the target. In addition, because ricocheting slugs can pose a serious safety hazard, it would be desirable to have a kinetic self-healing target configured to minimize or eliminate the potential for ricochets. As will become evident in this disclosure, the present invention provides such benefits over the existing art.
The illustrative embodiments of the present invention are shown in the following drawings which form a part of the specification:
Corresponding reference characters indicate corresponding parts throughout the several views of the drawings.
In referring to the drawings, the novel self-healing kinetic target with audible response of the present invention is depicted by way of example as the single direction kinetic spin target 10. As can be seen from
The shell 12 has a flat and circular central polymer strike zone or target plate 16, a lower attachment member or tab 18, and an upper attachment structure 20. The target plate 16 has a diameter of approximately six inches and a thickness of approximately one-quarter inch. The lower attachment tab 18 is generally rectangular, approximately one inch wide, and extends approximately three-quarters of an inch perpendicularly rearward from the lower edge of the back face of target plate 16. The attachment structure 20 is approximately one inch wide and two to three inches long.
Referring to
The attachment structure 20 also has a horizontal cylindrical tube 30 that runs along the outermost edge of the central portion 24 opposite the target plate 16. The cylindrical tube 30 has a central bore 32 that is approximately one-half inch in diameter, and approximately one inch long. The cylindrical tube 30 and its central bore 32 are both generally coplanar with the target plate 16 but run perpendicular to the perimeter of the target plate 16. As can be appreciated by one skilled in the art, the cylindrical tube 30 is configured for rotatable attachment to a support structure such as for example a rod or pole (not shown) such that the target 10 can be held in position by the rod or pole for target practice, yet is free to rotate about the rod or pole when struck by a projectile such as a bullet slug.
Referring to
The tab 34 has a width of approximately three-quarters inch, an overall length of approximately three-quarters inch, and extends approximately one-quarter inch beyond the radiused edge of the metal strike plate 14. Tab 38 extends in the opposite direction from the opposite side of the metal plate 14, and shares the same width of three-quarter inch. However, unlike the tab 34, the tab 38 has no adjoining slots (such as the slots 36). Rather, the tab 38 simply extends approximately one-quarter inch beyond the radiused edge of the metal strike plate 14.
Referring again to
Both of the slots 22 and 28 in the polymer are separated from the plane of the target plate 16 by approximately one-half inch. As can be appreciated, this separation between the slots 22 and 28, and the target plate 16, defines the separation or air gap 40 between the polymer target plate 16 of the shell 12 and the metal strike plate 14.
A second configuration of the present invention is shown at 100 in
Each of the shells 112 and 112A has an inner attachment member or tab 120 and 118A, respectively, and an outer attachment member or tab 118 and 120A, respectively, opposite their respective inner tabs 120 and 118A. Each of the tabs 118, 118A and 120, 120A is generally flat and rectangular, approximately one inch wide, approximately one-quarter inch thick, and extends approximately three-quarters of an inch perpendicularly upward from the inner face of its respective target plate 116 or 116A. The tabs 118, 118A and 120, 120A are substantially parallel to each other. However, outer tabs 118 and 120A each extend upward from a chord near the perimeter of their respective target plates 116 and 116A, while inner tabs 120 and 118A each extend upward from a chord approximately one quarter inch inward from the perimeter of their respective target plates 116 and 116A.
Referring particularly to
The shells 112 and 112A each have an attachment structure 150, 150A, that extends outward from its respective target plate 116, 116A. The attachment structure extends generally along a line parallel to, but slightly off-center of, a radius of the target plate 116, 116A. Further, the attachment structures 150, 150A extend outward in a generally coplanar manner from their respective target plates 116, 116A, for approximately one inch, then bend inward at an angle α of approximately 5 degrees to extend further to their respective cylindrical tubes 152, 152A. The angle α and the lengths of each portion of the attachment structures 150, 150A are configured such that as shown in
Each of the attachment structures 150 and 150A has a horizontal cylindrical tube 152, 152A that runs along the outermost edge of its corresponding attachment structure 150, 150A, opposite the target plate 116, 116A. Each cylindrical tubes 152 and 152A, has a corresponding central bore 154, 154A, that is approximately one-half inch in diameter, and approximately one inch long. The cylindrical tubes 152 and 152A, and their central bores 154 and 154A, both run generally perpendicular to the perimeter of the target plates 116, 116A, and when the target 100 is assembled, the cylindrical tubes 152 and 152A, and their central bores 154 and 154A are coaxial. As can be appreciated by one skilled in the art, the cylindrical tubes 152 and 152A are configured for rotatable attachment to a rod or pole, such as for example, the pole P, such that the target 100 can be held in position by the pole P for target practice, yet is free to rotate about the pole P when struck by a projectile such as a bullet slug.
Unlike the target 10, in which only one of the two tabs 34, 38 of metal strike plate 14 has side slots 36 (
As can be appreciated, and as shown in
All of the slots 122 in the polymer are separated from the plane of the target plates 116 and 116A by approximately one-half inch. As can be appreciated, this separation between the slots 122 and the target plates 116 and 116A, defines the separation or air gaps 140 and 140A between the polymer target plates 116 and 116A of the shells 112 and 112A, and the metal strike plate 114.
It can therefore be appreciated, and as depicted in the Figures, that in this way, the metal strike plate 114 can be releasably secured in the polymer shell 112, 112A such that the metal strike plate 114 is positioned parallel to the polymer target plate 116, but separated by a generally uniform separation or air gap 140, of approximately one-half inch, and at the same time the metal strike plate 114 is positioned parallel to the polymer target plate 116A, but separated by a generally uniform separation or air gap 140A, of approximately one-half inch.
In order to rotatably mount the target 100 to a rod or pole such as the pole P, each of the shells 112 and 112A has an attachment arm 150, 150A that projects from the side of the shells 112 and 112A, respectively, at a position approximately 90 degrees in rotation from the tabs 118 and 120 along the perimeter of the shells 112 and 112A. As can be appreciated, when the target 100 is properly mounted on a rod or pole, such as the pole P, is struck by a projectile, such as a bullet slug, the target 100 will rotate about the pole P to which it is attached due to the kinetic energy it absorbs from the force of the projectile's impact.
As can also be appreciated upon seeing this disclosure, one of ordinary skill in the art would understand that the separation between the metal strike plate 14 and the polymer target plate 16, and the separation between the metal strike plate 114 and the polymer target plates 116 and/or 116A, allows the target 10, 100 to generate a substantial audible response when a projectile directed at the target passes through the “self-healing” polymer of the target plate 16, 116 or 116A and strikes the metal strike plate 14 or 114. This contrasts with the highly muffled and nearly inaudible response encountered when shooting a projectile at a traditional “self-healing” target where the polymer has no metal backing or is positioned against or forms a coating over any rigid structural component in the target.
Further, and referring now to
While I have described in the detailed description a configuration that may be encompassed within the disclosed embodiments of this invention, numerous other alternative configurations, that would now be apparent to one of ordinary skill in the art, may be designed and constructed within the bounds of my invention as set forth in the claims. Moreover, the above-described novel self-healing targets with audible response 10 and 100 of the present invention can be arranged in a number of other and related varieties of configurations without expanding beyond the scope of our invention as set forth in the claims.
For example, it is not necessary that the entire target shell 12, 112 or 112A be constructed of “self-healing” polymer, so long as the body or shall contains a sufficient amount of self-healing polymer to enable the targeted areas to “heal”. It is therefore preferred that at least the plates 16 and one of the plates 116 or 116A be constructed of a “self-healing” polymer. It is also not necessary that the separation or gap 40, 140, 140A between the metal strike plate 14, 114 and the polymer target plate 16, 116, 116A be a particular dimension, or that it must be entirely uniform, so long as there is sufficient separation between the metal plate and the polymer plates to allow a projectile to strike the metal plate after passing through the polymer so as the separation allows the projectile to create a relatively unmuffled audible response when striking the metal plate.
Likewise, it is not necessary that the targets 10, 100 have a round shape, but can be constructed in virtually any desired shape, so long as the target's polymer and metal plates have a separation that performs and provides the benefits as outlined in this disclosure.
Of course, the metal plates 14, 114, and the polymer plates 16, 116 and 116A need not be the same shape or thickness, nor be fully uniform in thickness, so long as there is sufficient separation between the metal plate and the polymer plates to allow a projectile to strike the metal plate after passing through the polymer so as to allow the projectile to create a relatively unmuffled audible response when striking the metal plate.
Further, the separation between the plates 14, 114 and 16, 116 or 116A, respectively, can be set at different distances, other than the one-half inch described above, to best suit the ammunition being used on the target 10, or for other reasons. That is, it would be preferable to have a greater distance between the plates 14, 114 and 16, 116 or 116A, respectively, for a bullet with a long slug, such as for example a rifle bullet, as opposed to a bullet with a shorter slug, such as for example a pistol bullet. For example, a single target 10 can be constructed to have two different separations between the plates 14 and 16 by merely making the slots 22 and 28 wider than the strike plate 14 such that a spacer (not shown) can be selectively placed in the slots with the plate tabs on one side or the other of the tabs 18 and 20. In this way, when the spacers are placed on one side of the plate tabs, the plates 14 and 16 will have one separation there between, and when the spacers are placed on the other side of the plate tabs, the plates 14 and 16 will have a different separation there between.
Alternately, tabs for the strike plate 14 can be offset from the plane of the strike plate 14 such that, again, two different separations between the plates 14 and 16 can be had by simply turning the strike plate 14 around. Furthermore, the tab 18 and central portion 24 of the attachment structure 20 can be configured with more than one pair of horizontal slots, where each pair of slots is positioned at a difference distance from the target plate 16 so as to create multiple gaps 40 of differing widths between the plates 14 and 16 when the strike plate 14 is positioned in a selected pair of slots.
Furthermore, the target 10 or 100 can be adapted to attach to a stand (not shown), which may for example be a vertical pole or rod, such that the target 10, 100 will move or rotate from a first position to a second position relative to the stand when a projectile impacts the target's strike zone.
Additional variations or modifications to the configuration of the above-described novel self-healing target with audible response 10, 100 of the present invention may occur to those skilled in the art upon reviewing the subject matter of this invention. Such variations, if within the spirit of this disclosure, are intended to be encompassed within the scope of this invention. The description of the embodiments as set forth herein, and as shown in the drawings, is provided for illustrative purposes only and, unless otherwise expressly set forth, is not intended to limit the scope of the claims, which set forth the metes and bounds of my invention.
