While there are many options for displaying deer antlers that permit the antlers to be displayed either as a part of a simulated deer head or deer body or in connection with an outdoor related background, what is needed is an antler wall mount assembly that permits the user to display antlers in an attractive manner while conveying the user's interest in other sports such as football and baseball.


SUMMARY OF THE INVENTION

An assembly for mounting deer antlers is provided, the assembly generally comprising an enclosure, the enclosure generally shaped like a game ball such as a football, and comprising a front portion and a rear portion, the enclosure being adapted to couple end portions of main beams of the antlers to an inside surface of the enclosure rear portion such that portions of the antlers extend through lateral through openings, to an area outside the enclosure, the enclosure front and rear portions being removably coupled to one another.


The front portion of the enclosure comprises a rounded, generally hollow, fusiform configuration such that top and bottom ends are narrower than an equator portion. The front portion comprises a lace-like extension portion which simulates the laces of a standard American football. The lace-like extension portion is formed from a series of vertical and horizontal raised segments. The lace-like extension portion extends vertically such that approximately half the vertical and horizontal raised segments are above the equator portion and half are below.


In certain embodiments, simulated contrasting stripes are positioned near the respective ends of the front portion to simulate the stripes of some standard footballs.


The front portion comprises the lateral openings. The lateral openings are positioned on sides of the front portion proximate to the top end and are adapted to permit the front portion to partially enclose a lower perimeter of the antler main beams. The front and rear portions enclose the lower perimeter when the antlers are positioned within the enclosure and the front and rear portions are secured together.


The rear portion comprises a rear portion outer rim adapted for cooperative coupling with a front portion outer rim. Extending forward from an angled inside perimeter wall of the rear portion are one or more tabs. Each tab is flexible and biased exterior to the respective side of the perimeter wall to which the tab is mounted. The user can bend the tabs inwardly so as to permit the front portion outer rim to be moved against the rear portion outer rim. When released, the tabs return to the exteriorly biased position. When the front portion is mounted to the rear portion the tab's exterior bias applies pressure on an inside surface of the front portion, keeping the front and rear portions coupled together.


Although tabs are used to removably couple the front and rear portions together, other fastening mechanisms known in the art may also be used. For example, the front and rear portions may be coupled together with conventional and commercially available fasteners such as glue, snaps, hook and loop fasteners, threaded couplers (screws, bolts, etc.), pins, detents, and the like.


The rear portion comprises a generally flat rear outer surface which permits the assembly to be easily mounted against a flat wall using standard mounting hardware such as hooks, wires, cleats, nails, screws, and the like.


The inside perimeter wall defines an inside rear wall and interior shelf. The interior shelf is raised with respect to the insider rear wall such that, when the rear portion is mounted to the front portion, the interior shelf is closer to the front portion than the inside rear wall. This interior shelf is the surface to which the antlers are mounted. The interior shelf is adapted to receive a threaded fastener which is driven through a horizontal member of the antlers. The horizontal member can be artificial or natural. The horizontal member, for example, may comprise the skull portion to which the antlers are naturally attached. With respect to sheds, the horizontal portion may comprise wood, plastic, or other suitable material adapted to permit the main beams to be attached.


In another embodiment, the front portion of the enclosure comprises a rounded, generally hollow, semi-spheroid configuration resembling a baseball. In this embodiment, the front portion comprises simulated stitching which simulates the stitching of a standard baseball. The simulated stitching of this embodiment is formed from a series of simulated stitches.


In other embodiments, the assembly comprises a soccer ball configuration when viewed from the front.


In other embodiments, when viewed from the front, the assembly comprises respective configurations of a basketball, a tennis ball, a hockey puck, a golf ball, a volley ball, a bowling pin, and a billiards ball.

Referring to the figures, the antler wall mount assembly 12 of the preferred embodiment generally comprises an enclosure 14, the enclosure 14 generally shaped like a game ball such as a football, and comprising a front portion 16 and a rear portion 18, the enclosure 14 being adapted to couple end portions 20 of main beams 22 of antlers 24, directly or indirectly, to an interior shelf 64 of the enclosure 14 rear portion 18 such that portions of the antlers 24 extend through lateral openings 26, 28, to an area outside the enclosure 14, the enclosure 14 front and rear portions 16, 18, being adapted for removable coupling to one another. The antlers 24 can be antlers from deer, elk, or other ruminant mammals comprising antlers 24 or horns 24. The enclosure is adapted to permit antlers 24 secured from animals taken through hunting or other means or antlers 24 found as a result of a deer's annual shedding (“sheds”). Sheds 24 are found individually such that the main beams 24 are not found attached to a mounting member 68.


As shown, for example, in FIGS. 1 and 2, in the preferred embodiment, the front portion 16 of the enclosure 14 comprises a rounded, generally hollow, fusiform configuration such that front portion horizontal diameters 82, 84, of top and bottom ends 30, 32 are narrower than a mid-point horizontal diameter 34. In the preferred embodiment, the front portion 16 comprises a lace-like extension portion 36 which simulates the laces of a standard American football. As shown in FIGS. 1 & 2, the lace-like extension portion 36 is formed from a series of raised segments 38, 40 generally arranged vertically 38 and horizontally 40 with respect to an outer surface of the front portion. In a preferred embodiment, the lace-like extension portion 36 extends vertically such that approximately half the vertical and horizontal raised segments 38, 40 are above the equator portion 34 and half are below. In a preferred embodiment, the lace-like extension portion 36 is positioned to one side of center, as shown, for example, in FIG. 1. In other embodiments, the lace-like extension portion 36 is centrally positioned, such that the lace-like extension portion 36 is positioned below a mid-point between the lateral openings 26, 28.


In the preferred embodiment, the front portion 16 is formed from a hard material such as plastic. The lace-like extension portion 36 is formed from the same material and is integral to the remainder of the front portion 18. Though integrated within the front portion 16 in the preferred embodiment, the lace-like extension portion 36 extends outward from an outer surface 72 of the front portion 16 such that the lace-like extension portions 36 have a similar appearance as laces on a standard American football. In certain embodiments, simulated contrasting stripes 42, 44 are positioned near the respective ends 30, 32 of the front portion 16 to simulate the stripe of some standard footballs such as, for example, footballs used in college games. In some embodiments, simulated seams 46, 48 extend from, approximately, the top end 30 to the bottom end 32.


Although, the antler wall mount assembly 12 of preferred embodiments comprises a lace-like extension portion 36, contrasting stripes 42, 44, simulated seams, the assembly 12 need not comprise such lace-like extension portion 36, contrasting stripes 42, 44, and simulated seams. In other embodiments, for example, the assembly does not comprise simulated seams 46, 48 or stripes 42, 44.


Referring to FIG. 5, the front portion 16 comprises the lateral openings 26, 28. The lateral openings 26, 28 are positioned on sides of the front portion 16 proximate to the top end 30 and are adapted to permit the front portion 16 to partially enclose a lower perimeter 50 of the antler 24 main beams 22. Thus, the front and rear portions 16, 18 enclose the lower perimeter 50 when the antlers 24 are positioned within the enclosure 14 and the front and rear portions 16, 18 are secured together as shown in FIGS. 1 & 2.


Referring to FIGS. 2 & 3, and 7 the rear portion 18 comprises a rear portion outer rim 54 adapted for cooperative coupling with a front portion outer rim 52. In the preferred embodiment, the rear portion outer rim 54 comprises an oval configuration such that, as depicted in FIG. 7, the rear portion 18 shares the same upper and lower end horizontal diameters 82, 84 and mid-point horizontal diameter 34 as the front portion 16. Except for those portions of the front portion outer rim 52 comprising through openings 26, 28, the outer rims 52, 54 of the front and rear portions 16, 18 are generally the same shape and size so as to permit the front and rear portions 16, 18 to be coupled together and give the appearance that the rear portion 18 is a continuation of the front portion 16.


Extending forward from an angled inside perimeter wall 56 of the rear portion 18 are one or more tabs 58. Each tab 58 is flexible and biased exterior to the respective side of the perimeter wall 56 to which the tab 58 is mounted. The user can bend the tabs 58 inwardly so as to permit the front portion outer rim 52 to be moved against the rear portion outer rim 54. When released, the tabs 58 return to the exteriorly biased position. When the front portion 16 is mounted to the rear portion 18, the tab's 58 exterior bias applies pressure on an inside surface of the front portion 16, keeping the front and rear portions 16, 18 firmly coupled together. In other embodiments, the tabs 58 are coupled to, and extend from, the inside surface of the front portion 16, engaging the rear portion 18 perimeter wall 56 and securing the front 16 and rear portion 18 together.


In the preferred embodiment, there are four tabs 58, as shown in FIG. 6. However, there can be more or fewer tabs 58.
