## Background
CROSS-REFERENCE TO RELATED PATENT APPLICATIONS
This application claims the benefit of the filing date of U.S. provisional patent application Ser. No. 60/376,863 filed May 1, 2002.


This invention relates generally to outdoor shooting sports, and more particularly to an apparatus for dispensing shooting targets, and an apparatus for measurement and calibration of gun sights.
BACKGROUND AND SUMMARY OF THE INVENTION
The present invention is an apparatus, which can be secured to a vehicle, and which can be used to affix, transport, and deploy shooting sports equipment such as a target dispenser, a gun-sighting bench rest assembly, and the like.
Heretofore, a number of patents and publications have disclosed transportable apparatus, which attach to a vehicle, the relevant portions of which may be briefly summarized as follows:
U.S. Pat. No. 6,089,431 to Heyworth, issued Jul. 18, 2000, discloses a transportable hoist apparatus, which attaches to a receiver on a vehicle.
U.S. Pat. No. Des. 407,135 to DeWitt, issued Mar. 23, 1999, discloses a transportable clay pigeon launcher support device, which attaches to a receiver on a vehicle, and which comprises a square tube, and a rotatable platform.
U.S. Pat. No. 5,397,147 to Ducharme et al., issued Mar. 14, 1995, discloses a transportable work table apparatus, which attaches to a receiver on a vehicle, and which comprises a square tube, and a fixed platform.
U.S. Pat. No. 2,925,077 to Leubkeman, issued Feb. 16, 1960, discloses a target-dispensing device, which is attachable to a fixed object, such as a post.
In accordance with the present invention, there is provided an apparatus for affixing, transporting, and deploying shooting sports equipment with a vehicle, comprising: a receiver bar having a first end and a second end, the first end being attachable at to a vehicle; a riser comprising a lower section and an upper section, said riser being attachable at the lower section to the second end of said receiver bar; wherein the upper section of said riser further comprises a joining feature for affixing said shooting sports equipment to said riser.
In accordance with another aspect of the present invention, there is provided an apparatus for affixing, transporting, and deploying a target dispenser with a vehicle, comprising: a receiver bar having a first end and a second end, the first end being attachable to a vehicle; a riser having a lower section and an upper section, the lower section being attachable to the second end of said receiver bar; and a target dispenser attached to the upper section of said riser.
In accordance with another aspect of the present invention, there is provided an apparatus for affixing, transporting, and deploying a gun-sighting bench rest with a vehicle, comprising a receiver bar comprising a first end and a second end, attachable at said first end to a vehicle; a riser comprising a lower section and an upper section, attachable at said lower section to said second end of said receiver bar; and a gun-sighting bench rest attached to said upper section of said riser.
One aspect of the invention is based on the observation of problems with conventional techniques of affixing, transporting, and deploying shooting sports equipment in remote outdoor locations. To the best of the applicant's knowledge, no one single device offers the capability of effectively accomplishing all three objectives of affixing, transporting, and deploying equipment.
In many instances, it is desirable to transport such equipment into areas, which are substantially inaccessible with large vehicles and conventional equipment transporting means. The present invention enables fast and simple affixing of such equipment to a vehicle that is capable of accessing remote terrain, e.g. an all terrain vehicle. Furthermore, such equipment is frequently secured at the remote site to such objects as a vehicle spare tire and the like, as means to affix and immobilize the equipment. For example, the practice of attaching a target dispenser (used in dispensing skeet or trap shooting targets) to the spare tire of a vehicle (detached and lying on the ground) is generally unsatisfactory. A typical spare tire is not a satisfactory base, because it is not heavy enough to withstand the recoil of the target dispenser during target ejection, and thus it allows the dispenser to wobble uncontrollably during and after ejection. Any attempt to add weight to the spare tire, e.g. filling it with water, renders the spare tire generally unsatisfactory for its intended purpose.
The apparatus of the present invention can include a receiver bar, attachable to a vehicle; a riser, attachable to the receiver bar; and a joining feature for affixing shooting sports equipment to the riser.
The technique described above is advantageous because it enables fast and easy affixing of shooting sports equipment to a vehicle, ease of transportation of the equipment with the vehicle, and ease of deployment and use of the equipment upon arrival of the vehicle and equipment at the desired destination.
It is therefore an object of this invention to provide an apparatus for affixing, transporting, and deploying shooting sports equipment with a vehicle.
It is a further object of this invention to provide an apparatus for affixing, transporting, and deploying a target dispenser with a vehicle.
It is an additional object of this invention to provide an apparatus for affixing, transporting, and deploying a gun-sighting bench rest with a vehicle.

DESCRIPTION OF THE PREFERRED EMBODIMENT
For a general understanding of the present invention, reference is made to the drawings. In the drawings, like reference numerals have been used throughout to designate identical elements. In describing the present invention, the following terms have been used in the description: A target dispensing device is meant to describe any device that can throw, fling, or otherwise discharge a target object into a spatial volume, where a shooter may discharge a firearm at such object while it is in flight. Such target dispensing devices are typically used in the practice of skeet and trap shooting, wherein such targets are typically substantially disc shaped, made of ceramic composition, and often referred to as clay pigeons. A firearm is meant to describe any gun in general. A long gun is meant to describe a firearm comprising a long-barrel (i.e. a barrel of a length more than approximately twenty times its outside diameter); and a stock which is generally placed against the shoulder of the shooter, such as a shotgun, a rifle, a muzzle-loader, and the like. A sidearm is meant to describe a firearm comprising a short barrel (i.e. a barrel of a length less than approximately ten times its outside diameter), and a stock which is generally gripped with one hand of the shooter, and which is carried in a side holster, or concealed and carried in a body holster. A sidearm may be e.g. a pistol, a handgun, a derringer, and the like. Gun sighting is meant to indicate the practice of aiming a firearm, or the practice of calibrating the alignment of the mechanical or optical means, which is provided proximate to a gun barrel to ensure the accuracy of a gunshot.
Referring to FIG. 1, and in one embodiment, the applicant's transportable shooting device 100 comprises receiver bar 102, and riser 105. Receiver bar 102 comprises a first end 101, which is attachable to vehicle 400, and a second end 103, which is attachable to riser 105. In one embodiment, end 103 of receiver bar 102 comprises riser sleeve 104, and riser 105 comprises a lower section 107, wherein the outside dimensions of lower section 107 and the inside dimensions of riser sleeve 104 are such that a sliding fit of lower section 107 inside of riser sleeve 104 is attained.
FIG. 2 is a side elevation view of means to attach the riser 105 of the apparatus to the receiver bar 102 of the apparatus. Referring to FIG. 2, lower section 107 of riser 105 is engaged in riser sleeve 104. Riser sleeve upper locking bolt 108 and riser sleeve lower locking bolt 110 are threadedly engaged with riser sleeve upper locking nut 112 and riser sleeve lower locking nut 114 respectively. Riser sleeve locking bolts 108 and 110 extend through holes (not shown) in riser sleeve 104, such that the tips (not shown) of riser sleeve locking bolts 108 and 110 also engage the outer surface of lower section 107 of riser 105, when riser sleeve locking bolts 108 and 110 are tightened. Accordingly, riser 105 is immobilized and secured to receiver bar 102 when riser sleeve locking bolts 108 and 110 are tightened.
Riser sleeve upper locking nut 112 and riser sleeve lower locking nut 114 of FIG. 2 are joined to riser sleeve 104 preferably by welding. Riser sleeve upper locking nut 112 and riser sleeve lower locking nut 114 provide threads with which to engage riser sleeve locking bolts 108 and 110 to riser sleeve 104. Alternatively, if riser sleeve 104 is of sufficient wall thickness such that riser sleeve 104 may be tapped with threads, riser sleeve locking bolts 108 and 110 may be threadedly engaged directly with riser sleeve 104.
Riser 105 further comprises a joining feature at the upper section 109 of riser 105. Referring to FIG. 3, and in one embodiment, riser 105 comprises stud 116, which is suitably joined to upper section 109 of riser 105. Stud 116 is preferably joined to upper section 109 of riser 105 by welding, brazing or equivalent joining methods. Alternatively, stud 116 may be threadedly engaged with upper section 109 of riser 105, into a correspondingly threaded hole (not shown) into upper section 109.
In one embodiment shown in FIG. 1, upper section 109 of riser 105 comprises a platform knuckle 113 having a sleeve 115, which fits over riser tube 106. Platform knuckle 113 further comprises threadedly engaged locking bolt and nut 117, which is used to secure platform knuckle 113 to riser tube 106, as was previously described for the securing of riser tube 106 within riser sleeve 104. Stud 116 (see FIG. 3) is joined to sleeve 115 of platform knuckle 113 as previously described.
Various shooting sports equipment, or other equipment may be attached to the joining feature at upper section 109 of riser 105. Referring again to FIG. 3, and in the embodiment in which said joining feature is stud 116, a platform 118 may be joined to the upper section 109 of riser 105. In FIG. 3 platform 118 comprises a short section of angle iron. Platform 118 is shown in FIG. 3 as detached from upper section 109 of riser 105, and inverted. To join platform 118 to upper section 109 of riser 105, platform 118 is turned over, and stud 116 is directed through hole 120 of platform 118. Referring to FIG. 1, platform 118 is shown joined to upper section 109 of riser 105, and secured with platform nut 122.
In one embodiment, the apparatus of the present invention further comprises receiver means, which is suitably attached to the vehicle that is transporting the apparatus. FIG. 4 depicts receiver means for attaching the apparatus of the present invention to an all-terrain vehicle, which comprises a hitch plate 402 (see FIG. 5). Referring to FIG. 4, receiver means 124 comprises receiver socket 126, receiver stud 128, receiver nut 130, receiver lock bolt 132, and receiver lock nut 133.
Receiver socket 126 comprises a hollow cross section, and is typically fabricated from a short section of tubing. In one embodiment, receiver socket 126 is made of tubing having a square cross section. Receiver bar 102 comprises a square cross section, which achieves a sliding fit within receiver socket 126 when the end 101 of receiver bar 102 is engaged with receiver socket 126. Receiver locking bolt 132 is threadedly engaged with receiver locking nut 133, and with receiver bar 102, in the same manner in which riser tube lock bolt 108 is engaged with riser tube lock nut 112 (see FIG. 2), as previously described in this specification.
Referring again to FIG. 4, in a one embodiment, receiver bar 102 comprises a hole 136 drilled through the cross section thereof, and receiver socket 126 comprises a hole 138 drilled through the cross section thereof. When receiver bar 102 is engaged with receiver socket 126, a pin (not shown) may be inserted through the pair of aligned holes 136 and 138, thereby engaging receiver bar 102 with receiver socket 126. This method of engaging a receiver bar with a receiver socket is widely practiced in the art of automotive towing of trailers and the like.
FIG. 5 shows the receiver means of FIG. 4, attached to an all-terrain vehicle. Referring to FIG. 5, all-terrain vehicle 400 comprises hitch plate 402, which further comprises a hole therethrough (obscured by receiver socket 126). Receiver stud 128 (see FIG. 4) is engaged with the hole in hitch plate 402, and receiver nut 130 is threadedly engaged with receiver stud 128, which reversibly attaches receiver socket 126 and receiver bar 102 to all-terrain vehicle 400.
In the embodiment shown in FIG. 5, receiver means 124 further comprises angle adjustment bolt 137 and guide nut 139, which is suitably joined to receiver socket 126. In operation, angle adjustment bolt 137 is threadedly engaged with guide nut 139, and is tightened against hitch plate 402 of vehicle 400. In performing such tightening, angle adjustment bolt 137 on receiver means 124 provides adjustment of the angle at which apparatus 100 is transported, with respect to vehicle 400.
In an alternative embodiment, the apparatus of the present invention may be provided with additional means to secure it to a vehicle. Referring to FIG. 1, strap 140 is looped around riser 105, through one or more bars of cargo rack 404 of vehicle 400, and joined to itself through buckle 142. Strap end 144 is tightened through buckle 142 to remove all slack from strap 140, thereby securing transportable shooting apparatus 100 more forcibly to the vehicle 400.
FIG. 1 is a side elevation view of one embodiment of the apparatus of the present invention, comprising a target dispenser. Referring to FIG. 1, target dispenser 200 is joined to platform 118 of shooting apparatus 100. In one embodiment, target-dispensing apparatus 200 is joined to platform 118 by nut-and-bolt fasteners 144, 146, and 148 of FIG. 3, wherein platform 118 and shooting apparatus 200 are shown detached from upper section 109 of riser 105, and inverted.
In one embodiment, the transportable shooting apparatus 100 of FIG. 1 is deployed for use as shown, i.e. in the same condition in which it is transported. All-terrain vehicle 400 is of sufficient weight to absorb the recoil reaction resulting from the dispensation of a target by shooting apparatus 200. However, in some situations, such as all-terrain vehicle being of light weight, or being a three-wheeled vehicle, features of the present invention that improve the stability thereof are preferred.
FIG. 6 is a is a side elevation view of one embodiment of the apparatus of the present invention, comprising a receiver bar, a riser, and a target dispenser, wherein the riser further comprises anchoring features such that the apparatus is deployed in a more stable configuration for the dispensing of targets. Referring to FIG. 6, apparatus 100 is deployed with the bottom end 111 of riser tube 106 lowered, as indicated by arrow 134, such that the bottom end 111 thereof is in contact with ground 10. In one alternative embodiment (not shown) bottom end 111 is provided with a point that may be embedded into the ground. Riser tube upper lock bolt 108 and lower lock bolt 110 (see FIG. 2) are tightened against riser tube 106 as described previously in this specification, to secure riser tube 106 in the deployed position.
In a preferred embodiment, apparatus 100 is provided with an anchor plate assembly 170, which is fitted to bottom end 111 of riser tube 106. Anchor plate assembly 170 comprises plate 172, to the bottom side of which are joined spikes 174 and 175 by suitable means such as e.g., welding. Anchor plate assembly 170 further comprises post 176 joined to the top side of plate 172, and substantially perpendicular to plate 172. In one embodiment, anchor plate assembly 170 was fabricated of carbon steel, with plate 172 being 0.25 inches thick, 4 inches wide, and 12 inches long; spikes 174 and 175 being 6 inches long; and post 176 being 1 inch in diameter and 3 inches long.
In use, anchor plate assembly 170 is placed in contact with ground 10 directly beneath bottom end 111 of riser tube 106, and further depressed (typically by the user's foot) such that spikes 174 and 175 (shown in phantom) are driven into ground 10. Riser tube 106 is then lowered such that post 176 is disposed within and engaged with bottom end 111 of riser tube 106. As a result of such engagement, apparatus 100 is anchored to ground 10 in a manner that resists any torque of apparatus 100 around riser 106, or around receiver stud 128 (see FIG. 4) when a target is ejected by target dispenser 200. Thus, substantially all of the potential energy that is stored in spring 201 of cocked target dispenser 200 (not shown) is converted into kinetic energy of the target (not shown) when such target is dispensed. In a further embodiment, anchor plate may be reversibly joined to bottom end 111 of riser tube 106 by suitable means such as a threaded engagement therewith (not shown), or by a pin (not shown). It is strongly preferred that any such joining is reversible so that at any time, riser tube 106 may be withdrawn completely through sleeve 104 in the event that apparatus 100 is to be dismantled.
The transportable shooting apparatus of the present invention is preferably provided with several additional features, which enable the simple adjustment of the apparatus in order to obtain optimum performance from the equipment attached thereto. For example, and referring again to FIG. 1, riser tube 106 of apparatus 100 is preferably a cylindrical tube, and riser sleeve 104 is preferably a cylindrical sleeve. Accordingly, riser tube upper locking bolt 108 and riser tube lower locking bolt 110 of FIG. 2 are loosened, and riser tube 106 is swiveled in riser sleeve 104 to a desired alternative position, whereupon riser tube upper locking bolt 108 and riser tube lower locking bolt 110 are tightened, securing the shooting apparatus in the alternative position. FIG. 7 depicts one example of the shooting apparatus 100 swiveled and secured in an alternative position.
A further adjustment feature provides for the adjustment of the angle of the platform of the shooting apparatus. In one embodiment shown in FIG. 3, upper section 109 of riser 105 is provided with toothed washer 150, which is joined to upper section 109 of riser 105 by suitable means such as welding. Toothed washer 150 is substantially concentric with stud 116, and toothed washer 150 is provided with a plurality of teeth that are substantially identical to tooth 152, around at least a portion of the circumference thereof. Platform 118 is provided with locating pin 154 for engagement with tooth 152 and an adjacent tooth, or with other pairs of teeth, when platform 118 is secured to upper section 109 of riser 105.
The engagement of pin 154 with toothed washer 150 is therefore incrementally adjustable along an arc represented by arcuate arrow 156 of FIG. 3. Referring to FIG. 1, the position of platform 118 is correspondingly adjustable along the arc represented by arcuate arrow 156. Such adjustability of platform 118 enables the corresponding adjustment of the plane (indicated by line 160) in which targets are discharged from the target dispenser 200, through a range of positions partially indicated by arcuate arrow 158. Such adjustability is desirable to the user, because it enables the simulation of the flight trajectories of a variety of flushed game birds, from those having a substantially vertical flight path to those having a substantially horizontal flight path.
The adjustability of platform 118 by the engagement of a toothed washer with a pin is incremental as presently described, and shown in FIGS. 1 and 3. However, it will be apparent to those skilled in the art that there are many mechanisms known in the mechanical arts for providing continuous adjustability of a platform that is secured to a riser. It is to be understood, therefore, that such continuous adjustability is encompassed by the present invention.
FIG. 8 is a side elevation view of another embodiment of the apparatus of the present invention, comprising a gun-sighting bench rest. Referring to FIG. 8, gun-sighting bench rest 300 of transportable shooting apparatus 100 comprises base 302, gunstock pad 304, gun barrel support bar 306, and gun barrel support V-rest 308. Base 302 further comprises mounting tab 303, through which is provided a hole (not shown), such that base 302 is secured to upper section 109 of riser 105 using nut 122, as was described for the securing of platform 118 to upper section 109, and shown in FIG. 1.
FIG. 9 is a side elevation view of the embodiment of FIG. 8, shown in use in the sighting of a long gun. Referring to FIG. 9, long gun 450 is positioned with barrel 452 resting in V-rest 308, and gunstock 454 resting on pad 304. The height of V-rest 308 is made adjustable by the provision of threaded rod 310, on which locking nuts 312 and 314 are threadedly engaged.
FIG. 10 is a side elevation view of the embodiment of FIG. 8, shown in use in the sighting of a sidearm. Referring to FIG. 10; sidearm 460 is positioned with barrel 462 resting in V-rest 308, and gunstock (concealed by shooter's hands) resting on pad 304. The location of V-rest 308 upon barrel support bar 306 has been adjusted to accommodate the short length of the barrel 462 of sidearm 460. In one embodiment, the adjustability of the position of V-rest 308 upon barrel support bar 306 is provided by a series of holes (not shown) drilled along the length of barrel support bar 306. In another embodiment, the adjustability of the position of V-rest 308 upon barrel support bar 306 is provided by a slot (not shown) milled along the length of barrel support bar 306.
The structural components of the apparatus of the present invention may be made of any suitable materials of construction known in the mechanical arts. Such materials are preferably inexpensive, readily available from common industrial supply wholesalers, and sufficiently lightweight such that one person may assemble the apparatus in its various configurations. For example, the apparatus may comprise components made of steel, aluminum, plastic, composite materials such as fiber-reinforced polymer, and the like.
In the embodiment shown in FIG. 1, receiver bar 102 was made of 1.5 inch square steel tubing with a 0.25 inch wall thickness. Riser sleeve 104 was made of steel tubing 2.375 inches in outside diameter, 2.00 inches in inside diameter, and 12 inches in length.
