Hence, specific dimensions and other physical characteristics relating to the embodiments disclosed herein are not to be considered as limiting, unless the claims expressly state otherwise.
(26) Referring first to FIG. 1, there is shown target apparatus 100 in accordance with the present invention. As illustrated in FIG. 1, apparatus 100 generally comprises target 10, swing arm 20, control module 30, control panel 40 of control module 30, protective plate 50 behind which control module 30 is disposed, and stand 60. Plate 50 ballistically shields control module 30 from impact by bullets fired at target 10. Stand 60 includes base 62 and stanchion 64. Control module 30 and plate 50 are each individually mountable to stanchion 64, which is disposed therebetween, with the front-facing side of control module 30 interfacing the rear-facing side of plate 50. Stand 60 is configured to support control module 30 and protective plate 50 while swing arm 20 and target 10 are unmoving or are moving linearly and/or rotationally in the directions indicated by arrows 70 and 74 shown in FIG. 2.
(27) Swing arm 20 is straight and has a generally elongated shape that extends between a first end 22 and an opposite second end 24. In the shown embodiments, swing arm 20 has a square, hollow cross-section, as best seen in FIGS. 6 and 7. The first end 22 of swing arm 20 is removably attached to target 10, which may comprise any known material used for shooting targets including, without limitation, aluminum or other light metals, paper, rubber, or plastic. As further shown in FIGS. 1 and 2, target 10 may include concentric circles or other visual media.
(28) Referring now to FIGS. 2 to 4 and FIGS. 6 to 10, swing arm 20 is connected to and extends through the housing 32 of control module 30. Swing arm 20 is adapted move longitudinally relative to control module 30 along axis 26 in the directions indicated by double-headed arrow 70 (FIG. 2). Additionally, swing arm 20 is adapted to rotate about control module axis of rotation 72 in the directions indicated by arrows 74, which preferably allows target 10 to be moved in an arc of at least 180 degrees and preferably up to almost 360 degrees about control module axis of rotation 72, and may, for example, pass through and/or assume the positions shown in FIGS. 3 and 4 during operation of target apparatus 100. Thus, target 10 is randomly moveable linearly and angularly in multiple directions. In some embodiments, swing arm 20 is also pivotally connected to control module 30 such that target 10 can move closer to or farther away from a shooter using the device. In this manner, apparatus 100 of the present invention uniquely allows target 10 to move in more than one plane relative to a shooter/user of apparatus 100.
(29) Control module 30 includes drive assembly 34 disposed within control module housing 32. In the illustrated embodiment of apparatus 100 target 10 is able to translate along the longitudinal axis 26 of swing arm 20, and/or move angularly about axis of rotation 72 under the influence of drive assembly 34 as directed by a controller 36 disposed within housing 32 of control module 30.
(30) In the embodiments of apparatus 100 depicted herein, drive assembly 34 includes first electric motor 42 and second electric motor 44, which are best seen in FIGS. 9, 11, 13A, 13B, 14 and 15. First motor 42 is adapted to move swing arm 20 and target 10 along a linear path defined by the longitudinal axis 26 of swing arm 20. Second motor 44 is adapted to rotate control module 30, and thus swing arm 20 and target 10, relative to stand 60 about control module axis of rotation 72. The present invention further comprises one or more position sensors to provide information about target location and speed to the control module 30.
(31) Controller 36 includes a preprogrammed or programmable microprocessor or other logic device. Controller 36 is operably connected to each of motors 42 and 44, and is in electrical communication with control panel 40 shown in FIG. 5. Control panel 40 may include a plurality of analog or digital inputs. As illustrated in FIG. 5, inputs to control panel 40 may include an on/off switch, a USB input, a mode dial, a speed control dial, and a range control dial. Target apparatus embodiments according the present invention further comprise software that includes preset operating modes defining, speed, path, and duration. However, the present invention further comprises user interfaces, such as a USB interface, that allows programming by graphical user interface or free form using a PC or other user interface. The present invention preferably further comprises means of receiving remote operating instructions using a radio frequency remote control or Bluetooth receiving device.
(32) In one exemplary embodiment, the controller 36 receives input from pressure transducers functionally connected to target 10. Input from said transducers is relayed to control module 30 as an input to the microprocessor program for motion of swing arm 20. Such input from the transducers may be used by the controller of control module 30 to alter the speed or path of target 10.
(33) Apparatus 100 preferably includes an AC Charger that takes standard 120 Volt AC house current and converts it to 12 Volts DC current for charging of an on-board battery of control module 30.
(34) Referring to FIGS. 6 to 12, control module housing 32 comprises plate 38 that defines a control module chassis to which drive assembly 34 is attached. During use of apparatus 100, exterior surface 80 of plate 38 and the front side of protective plate 50 oppose a shooter aiming at the face of target 10. In the depicted embodiment, control module plate 38 is planar, with axis 72 generally normal thereto, as best seen in FIGS. 9 and 10. Control module housing 32 defines one or more circumferential sidewalls 82 extending rearward from plate 38. In the depicted embodiment, housing 32 is octagonal, thus approximating a cylindrical shape, with control panel 40 attached to one of the eight housing sides. Axis 26, along which swing arm 20 is oriented and moveable, extends through diametrically opposite sidewalls 82.
(35) Control module housing 32 of the depicted embodiment defines planar rear wall 84 that is substantially parallel with plate 38. Portions of the housing sidewall(s) 82 may be integrally formed with housing rear wall 84, and plate 38 and sidewall(s) 82 are selectively attached through mating fasteners 86 to secure housing 32 to enclose the interior of control module 30.
(36) As best seen in FIGS. 2, 9, 10 and 12, control module 30 is mounted to stanchion 64 through mounting tongue 90 of hanger mount 92, which is receivable into the upper end of stanchion 64, whereby the position and orientation of hanger mount 92 are fixed relative to stand 60 during operation of apparatus 100. Hanger mount 92 is disposed adjacent to the front, exterior surface 80 of plate 38, with tongue 90 extending radially relative to axis 72. In the depicted embodiment, tongue 90 is affixed to and extends beyond the periphery of hub 94 of hanger mount 92. Hub 94 defines a circular flange portion from which axially extends cylindrical collar portion 96. Collar portion 96 is receivable of the forward end of drive shaft 98 that extends along axis 72 through plate 38. Collar 96 and drive shaft 98 are secured to each other in a known manner that prevents their axial and rotational movement relative to each other. Drive shaft 98 and second motor 44 are operably coupled through drive train 110. Motor 44 and drive train 110 are both secured to chassis 38 inside housing 32, and comprise part of first control module subassembly 102 shown in FIGS. 13A and 14. Accordingly, hanger mount 92 is drivably rotated in angular directions about axis 72 relative to control module chassis 38, by second motor 44 through drive train 110. When apparatus 100 is operational, hanger mount 92 is fixed relative to stand 60. Control module 30, swing arm 20 coupled thereto, and target 10 attached to swing arm end 22, are thus moveable in angular directions about axis 72 under the influence of second motor 44 during operation of apparatus 100.
(37) Control module 30 also comprises second subassembly 104, which is partially shown in FIGS. 13B and 15. Second control module subassembly 104 comprises elongate guide member 114 that is attached to first control module subassembly 102, and first electric motor 42 attached to guide member 114. Elongate guide member 114 defines channel 116 receivable of swing arm 20 and extending between longitudinally opposite first and second axial ends 118 and 120, respectively. Channel axial ends 118, 120 are open to the exterior of housing 32 through sidewall(s) 82. Each end 118, 120 is fitted with a self-lubricating bushing 122 that both surround and together define longitudinal axis 26 (FIG. 13B). When received in channel 116, swing arm 20 slidably engages bushings 122, and axes 26 and 26 are substantially coextensive and axially surrounded by portions of channel 116.
(38) Between channel axial ends 118, 120 a longitudinal section 124 of channel 116 is configured such that it does not axially surround axis 26. Within section 124, guide member 114 is provided with a pair of spaced, parallel roller bearings 126 whose rotational axes extend in directions perpendicular to axis 26 and lie in an imaginary plane parallel to axis 26, as best shown in FIG. 13B. When received within channel 116, swing arm 20 is supported by bearings 126. The output shaft of motor 42 is provided with friction wheel 128 whose outer diameter frictionally engages interfacing side surface of swing arm 20 that extends along swing arm axis 26, at a contact location axially between bearings 126. Rotation of motor 42 and friction wheel 128 induce linear movement of swing arm 20 along axis 26 relative to control module 30. Swing arm 20 and target 10 connected to swing arm end 22 are thus moveable in linear directions along longitudinal axis 26 under the influence of first motor 42 during operation of apparatus 100.
(39) Control module 30 also comprises third subassembly 106, which is partially shown in FIGS. 13C and 16. Third control module subassembly 106 comprises support member 130 that is attached to the interior surface of plate 38 of first control module subassembly 102. Control panel 40 is in electrical communication with controller 36, and is attached to exterior of a housing sidewall 82 and an abutting portion 132 of support member 130 that faces radially outward relative to axis 72. In the depicted embodiment, a first part of controller 36 is mounted to support member 130 within housing 32, and a second part of controller 36 is mounted to chassis 38 as shown in FIGS. 13A and 14. Control module 30 may be provided with a handle 134 (FIG. 12) to facilitate the portability of apparatus 100.
(40) While this invention has been described with respect to at least one embodiment, the present invention can be further modified within the spirit and scope of this disclosure. This application is therefore intended to cover any variations, uses, or adaptations of the invention using its general principles. Further, this application is intended to cover such departures from the present disclosure as come within known or customary practice in the art to which this invention pertains and which fall within the limits of the appended claims.
