Description

REFERENCE TO RELATED APPLICATIONS
• This application claims the benefit of U.S. Provisional Ser. No. 60/692,813 filed on Jun. 22, 2005, the entire contents of which are hereby incorporated by reference.
FIELD OF THE INVENTION
• The present invention relates generally to shooting targets, and more specifically, to movable shooting targets such as those used in automated targeting systems found in shooting ranges.
BACKGROUND OF THE INVENTION
• Various types of shooting targets have been developed and sold, including both stationary and moving targets. Their designs vary widely and are largely driven by the particular needs of the shooter and the specific environment in which the targets are used.
• For instance, standard bulls-eye type targets having a retrieval drive mechanism powered by an electric motor are commonly found in shooting range firing lanes and are used by shooters who want to practice shooting at a stationary target. Pop-up type targets and moving targets, on the other hand, provide the shooter with a more dynamic target environment, and sometimes move the target with a drive mechanism that is powered by either pneumatic, electric or hydraulic means.
• Some examples of different types of shooting targets are disclosed in U.S. Pat. No. 6,808,177 issued to Dehart; U.S. Pat. No. 6,325,376 to Elliott et al.; U.S. Pat. No. 5,232,227 to Bateman and U.S. Pat. No. 3,515,388 to Zachmeier.
SUMMARY OF THE INVENTION
• According to one aspect of the invention, there is provided a shooting target apparatus that comprises a frame, an obstruction, a drive mechanism, a movable target holder, and a target, whereby activation of the drive mechanism moves the target between generally coplanar concealed and presented positions. When the target is in the concealed position it is hidden from a shooter by the obstruction, and when the target is in the presented position it is revealed to the shooter.
• According to another aspect of the invention, there is provided a shooting target apparatus that comprises a frame, an obstruction, a movable target holder generally located behind the obstruction and including a pivot arm pivotally connected to the frame, a pneumatic drive mechanism, and a target. Activation of the pneumatic drive mechanism causes an air cylinder to tilt the movable target holder about a pivotal connection so that the target is moved between a concealed position and a presented position.
• According to yet another aspect of the invention, there is provided a shooting target apparatus that comprises a frame, an obstruction, a movable target holder generally located behind the obstruction and including a plurality of linkage members, a pneumatic drive mechanism, and a target. Activation of the pneumatic drive mechanism causes an air cylinder to pivotally move a plurality of linkage members so that the target is moved between a concealed position and a presented position.

DESCRIPTION OF PREFERRED EMBODIMENTS
• The shooting target apparatus disclosed herein is a pneumatically-driven device that provides a shooter with a dynamic and engaging target shooting experience and can be used in a number of different capacities, including indoor and outdoor training, competition, and recreational settings. Depending upon the particular manner in which it is used, the shooting target apparatus can be set up by itself as a stand-alone target, with other targets as part of a larger shooting course, in a traditional shooting lane, or in any other target shooting application known to those skilled in the art.
• With reference toFIGS. 1-4, there is shown a first embodiment of ashooting target apparatus10 that tilts a target, such as a hostage taker target, between several generally coplanar positions, some of which reveal the target to the shooter and some of which hide the target behind an obstruction. According to the embodiment shown here, shootingtarget apparatus10 includes aframe14, anobstruction16, amovable target holder18, adrive mechanism20, and atarget22.
• Frame14 acts as a foundation for supporting the other components ofshooting target apparatus10, and generally includes abase28, a pair ofmounting receptacles30,32, a pair ofupright posts34,36, and abracket42. Of course, other frame constructions can also be used, including frames formed with plates, ones having wheels or other components for improved portability, or ones made from materials other than steel, to name but a few possibilities.Base28 preferably includes several, transversely-connected steel members that lie on the ground to provide a solid foundation for the apparatus.Mounting receptacles30,32 are welded or otherwise attached tobase28 and receiveposts34,36, respectively, so that the posts are maintained in a vertically-upright and generally parallel orientation. Quick-release pins38,40, which can be connected to mountingreceptacles30,32 with cables to prevent them from being lost, are used to non-permanently secure the upright posts in their corresponding receptacles. This makes for easy assembly and disassembly of the shooting target apparatus. Because of their similarity, a separate description ofpost34 has been omitted.Bracket42 is securely fastened toframe28 and extends upwards so thatdrive mechanism20 can be attached to it and has a component to which it can anchor itself.
• Obstruction16 is generally located in front oftarget22 and simulates an object, such as a hostage, that hides or otherwise blocks the target from the shooter. The obstruction is preferably sized to block the entire target whenapparatus10 is in a concealed position, however, it could be designed to block only a portion of the target and thereby leave a portion exposed for the shooter to aim at. Preferably,obstruction16 andtarget22 conform with the guidelines set forth by the International Practical Shooting Confederation (IPSC), however, other types and size targets could be used as well. As an example,obstruction16 can be the same type of target as thetarget22, only turned around backwards so that the indicia on the target does not face the shooter. Although a stationary obstruction is shown here, it is also possible to couple the obstruction to drivemechanism20 or some other mechanism so that the obstruction also moves during operation.
• Movable target holder18 supportstarget22 as it is tilted between several generally coplanar positions, including the concealed and presented positions mentioned above. According to one embodiment, the movable target holder includes apivot arm50, across member52, apivot bracket54, a pair ofmounting receptacles56,58, a pair ofposts60,62, and an actuatormain frame64. As its name suggests,pivot arm50 is pivotally attached tobase28 so that it can move through an angular range of motion that spans a number of generally coplanar positions.Cross member52 is transversely attached topivot arm50 and supportsmounting receptacles56,58 at each of its ends. As previously explained in greater detail, each of the mounting receptacles secures apost60,62 in a generally upright orientation and can utilize quick release pins for easy assembly and disassembly.Pivot bracket54, which is best seen inFIG. 4, extends outwards and away frompivot arm50 and provides a connection point fordrive mechanism20 so that movement generated by the drive mechanism can be coupled tomovable target holder18.
• Actuatormain frame64 generally extends betweenbracket42 of the frame andpivot bracket54 of the movable target holder, and is designed to maintain two or more pneumatic cylinders in a generally coaxial alignment. The actuatormain frame64 can be constructed from angle iron or any other appropriate material, and includes anti-rotation features70-76 that prevent the air cylinders from rotating during operation. These features include one or moreslotted blocks70 which extends from an end of actuatormain frame64 and captures a flat section of the air cylinder rods so that it is prevented from rotating. The slottedblock70 is welded to aslide plate72 that slides in and out of a space formed with spacers and between asteel cover plate74 and actuatormain frame64. In this manner, the slottedblock70 can move with the drive mechanism as it cycles through a range of motion. Aswitch actuator plate76 can be welded to the opposite end ofslide plate72 and can interact with mechanical and/or electrical switches that provide data regarding the position of the air cylinders.
• Drive mechanism20 uses pressurized air to tiltmovable target holder18 through a variety of generally coplanar positions, and generally includes anair connection80, a valve82, and a pair of actuators orair cylinders84,86. Pressurized air from a compressor or some type of air rail is provided to connection80 (all air connections preferably use push lock or other quick-release fittings) and is regulated by an electrically controlled valve82.Air connection80, as well as other components of the pneumatic drive mechanism, can be protected from stray bullets with a shield likecomponent88. Each of theair cylinders84,86 is preferably a bi-direction, single-rod pneumatic cylinder, and when they are used in a serial or end-to-end arrangement, it allows for several different positional combinations. According to a first presented position (not shown), bothair cylinders84,86 have their rods retracted within their cylinders, which results intarget22 being tilted out to the right ofobstruction16. This provides the most retracted or shortest overall length that the pair of cylinders can assume, and is referred to as a right-presented position. In a concealed position (shown in phantom), one of theair cylinders84,86 is retracted and one is extended; this results intarget22 being located directly behind and therefore hidden byobstruction16. According to a left-presented position (shown in solid lines), both air cylinders are extended so thattarget22 is tilted out to the left ofobstruction16.Air cylinder86 preferably has a rod end attached tobracket42 with a clevis joint or some other rotatable connection, and a cylinder end that is attached toair cylinder84. Similarly,air cylinder84 includes a cylinder end attached tocylinder86, as just stated, and a rod end attached to pivotbracket54 via a second clevis joint.
• Target22 can be attached toposts60,62 with various types of mounting hardware (not shown) and is sized in relation toobstruction16 so that it can be selectively concealed from and presented to the shooter. Target90 is a generally flat component that preferably has target-related indicia on its surface, such as those that conform with International Practical Shooting Confederation (IPSC) guidelines. Furthermore, target90 can be in the shape of a person, animal, or some inanimate object, with one or more zones indicating the quality of different shots, for example.
• During operation,drive mechanism20 tilts target22 between generally coplanar concealed and presented positions. Beginning with the concealed position shown in phantom lines, one of the twoair cylinders84,86 is extended and one is retracted (in this particular embodiment the cylinder on the right is retracted and the one on the left is extended, however, they could be reversed). If theair cylinder86 on the right is activated so that it transitions from a retracted position to an extended position, then both air cylinders will be in extended positions andmovable target holder18 will be tilted to the ‘left presented’ position shown in solid lines. If, on the other hand,air cylinder84 is activated, then it would transition from an extended position to a retracted position so that both air cylinders would be retracted. This results in a ‘right presented’ position that is not shown in the drawings for reasons of figure clarity. It should be recognized that throughout the range of motion that occurs when theapparatus10 transitions between the various concealed and presented positions, target90 generally stays within a common plane.
• Turning now toFIGS. 5-7, there is shown asecond embodiment110 of a shooting target apparatus that moves a target between one of several generally coplanar positions; only this embodiment utilizes a movable target holder employing a spring-loaded, linkage-type construction instead of the titling arrangement previously described. According to the embodiment shown here, shootingtarget apparatus110 generally includes aframe114, anobstruction116, a movable target holder118, adrive mechanism120, and atarget122.
• Frame114 provides structural integrity to shootingtarget apparatus110, and preferably includes abase128, a number of mounting receptacles130-136, a number of upright or vertical posts138-144, and drive mechanism mounting brackets146-150. As before, the base128 preferably includes a number of elongated, transverse members that lie on the ground and provide a foundation for the rest of the apparatus. As an example best seen inFIG. 7, the base128 can have a configuration where a single, long frame component is attached to a number of separate transverse members. Mounting receptacles130-136 respectively receive posts138-144, which in turn are used to support one or more obstruction panels. The drive mechanism brackets maintaindrive mechanism120 in a generally horizontal position that is elevated off of the ground and limit the linkage members range of motion. They include astop146 the prevents the linkage members from overextending, acylinder mount bracket148, which is used to mount a pair of air cylinders and providedrive mechanism120 with a connection point, and ananti-rotation plate150. The anti-rotation plate is fixedly attached to theframe114 with small angle irons and keeps the air cylinders of the drive mechanism from rotating.Anti-rotation plate150 can also be used to mount optional switches, mechanical and/or electrical, which can read and convey the position of the various air cylinders. Its construction is somewhat similar to the anti-rotation features previously explained.
• Obstruction116 protects the components ofdrive mechanism120 and hides thetarget122 when it is in a concealed position. According to a preferred embodiment, the obstruction includes alower shield component156, which may be comprised of a single panel or multiple panels, and anupper shield component158.Lower shield156 is secured to posts138-144 by one of a number of attachment techniques, whileupper shield158 is just secured to posts140-142, which are longer thanposts138 and144 located on the ends of the obstruction.
• Movable target holder118 uses a spring-loaded linkage-type design to pivot thetarget122 between one of several generally coplanar positions, and generally includes a pair oflinkage members166,168, across member170, a pair ofposts172,174, and a pair ofsprings176,178. Each of thelinkage members166,168 is pivotally attached to frame114 at a lower end andcross member170 at an upper end, and preferably use pivotal connection hardware such as spacer plates, shoulder bolts, flange bearings, and thrust washers.Cross member170 is an elongated, horizontally aligned component that extends the general width of the movable target holder118 and maintains a proper spacing betweenposts172 and174.Springs176,178 are diagonally attached across the linkage members, and assist with the proper movement and spacing of the movable target holder118 during operation. Additional components, such as stops or bumpers could be used to limit the range of motion of the linkage members.
• As with the previous embodiment,drive mechanism120 uses a pair of bi-directional, single-rod actuators or air cylinders to move the target between the various coplanar positions, and generally includes anair connection186,valves188, and a pair ofair cylinders190,192. The two air cylinders are connected in a serial or end-to-end fashion and can drive the movable target holder118 between right presented, concealed, and left presented positions, as previously described. Moreover, the rod end ofair cylinder190 is securely attached tocylinder mount bracket148, and the rod end ofair cylinder192 is connected tolinkage member166. For each air cylinder connection requiring a pivoting motion, it is preferable to use a clevis joint or some other type of pivotal connection.
• Target122 is securely attached toposts172,174 so that it can move together with the movable target holder118. Because thetarget122 is similar to that already described, a second, duplicate description has been omitted.
• During operation, activation ofdrive mechanism120 causes movable target holder118 to move between several coplanar positions, as was the case with the previous embodiment. Beginning with a concealed position (shown in phantom) wheretarget122 is hidden behindobstruction116, only one of the twoair cylinders190,192 is extended (in this particular embodiment,air cylinder190 is retracted andcylinder192 is extended). Ifcylinder190 is activated, then it will go from a retracted position to an extended position, this in turn causes the linkage members of movable target holder118 to pivot to the “left presented” position shown in solid lines so thattarget122 is visible to the shooter. Conversely, ifair cylinder192 is activated, then it transitions from an extended position to a retracted position so that both air cylinders are retracted and thetarget122 assumes a “right presented” position (not shown).
• It is to be understood that the foregoing description is not a definition of the invention itself, but is a description of one or more preferred exemplary embodiments of the invention. The invention is not limited to the particular embodiment(s) disclosed herein, but rather is defined solely by the claims below. Furthermore, the statements contained in the foregoing description relate to particular embodiments and are not to be construed as limitations on the scope of the invention or on the definition of terms used in the claims, except where a term or phrase is expressly defined above. Various other embodiments and various changes and modifications to the disclosed embodiment(s) will become apparent to those skilled in the art. All such other embodiments, changes, and modifications are intended to come within the scope of the appended claims.
• For instance, it is possible to replace the pneumatic drive mechanism with another adapted power source, such as an electric motor, a hydraulic drive mechanism, or some other drive mechanism know to those skilled in the art. Furthermore, one or more protective angle irons or other shielding-type components can be added to any one of the shooting target embodiments to protect their components from stray bullets. This is particularly useful for protecting the components of the pneumatic drive mechanism, although other components can and should be protected as well. Even though most of the components described above are preferably made of steel, they could alternatively be made of aluminum or another metal, plastic, composite, wood, or any other suitable material known to those skilled in the art, such as Amortex which is a bullet proof material made of fiberglass and resins.
• Furthermore, one of any number of additional features could be added to any one of the embodiments described above. For example, position sensing switches could be used throughout any one of the shooting targets in order to provide an electronic controller with feedback as to the position of one or more components. It is also possible to use the shooting target in a larger targeting system where some type of main control unit communicates with each of the shooting targets so that they function in a coordinated manner as the shooter advances through a course. In that regard, the various shooting targets and the main control unit may communicate via some type of wired medium or even a wireless link. These are, of course, only some of the additional features that may be used with any number of the embodiments disclosed herein, as other features and aspects of the shooting targets would be apparent to those skilled in the art. Anelectrical connection40 is located on the pivot arm and can connect an electronic control system of the shooting target to power and/or a larger control network.
• In a preferred embodiment, software is used to randomly activate one of the two air cylinders so that a shooter does not know in which direction the target will be presented. The software can provide at least two options for target presentation. One option is to have the target advance either to the left or right and stay in that position until the shooter advances through the course. Another option is to have the target oscillate back and forth while the shooter is at the shooting target until advancing through the course.
• As used in this specification and claims, the terms “for example,” “for instance,” “such as,” and “like”, and the verbs “comprising,” “having,” “including,” and their other verb forms, when used in conjunction with a listing of one or more components or other items, are each to be construed as open-ended, meaning that that the listing is not to be considered as excluding other, additional components or items. Other terms are to be construed using their broadest reasonable meaning unless they are used in a context that requires a different interpretation.
