DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference now to the drawings, and in particular to FIG. 1 thereof, a new bow nock device embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.

From an overview standpoint, the bow nock device is adapted for use with a conventional release aid for extending the useful life of a bowstring by eliminating wear caused by the release aid chafing the bowstring and additionally for improving accuracy by aligning an arrow directly in front of the release aid to maintain the arrow at about a 90 degree angle relative to the longitudinal axis of the bow during the entire arrow release process. See FIG. 1 .

The internal facing protrusions more than stabilize the nock end of the arrow. The arrow is rarely at a true 90 degree angle to the nocking device or bow string. These half-moon lobes allow the arrow to free float or pivot and change angle approximately plus or minus 10 degrees within the nocking device while maintaining a true nocking point of the arrow on the bow string, therefore allowing a clean arrow flight without the arrow binding in the nocking device. Without these lobes the pressures exerted on the arrow at full draw would cause a slight downward bend in the arrow and a pre-loading or the arrow rest which also causes poor arrow flight.

With reference now to FIGS. 1-6 and more specifically, it will be noted that a new bow nock device 10 for use with a conventional release aid 122 is shown.

The bow nock device 10 comprises a U-shaped member 20 , formed of 7075-T6 aluminum alloy, attachable to the bowstring 124 for gripping by the release aid 122 and for positioning a nocked end 126 of the arrow between the ends 24 and 26 thereof. The U-shaped member 20 has a transverse bowstring receiving groove 32 and 36 formed on a first side 64 of each end 26 . Each groove 32 and 36 has an eccentrically positioned flared mouth 34 and 38 formed on an external end thereof for preventing bowstring chafing. The U-shaped member 20 additionally has internal facing protrusions 56 and 58 formed proximal each end 24 and 26 thereof co-pending with the end 126 of the arrow for stabilizing the same. Each end 24 and 26 of the U-shaped member 20 also has a pair of countersunk through holes 46 and 48 , 42 and 44 , the countersinks being formed on a second side 62 of the U-shaped member 20 opposite the bowstring receiving grooves 32 and 36 . The U-shaped member 20 has a maximum thickness at the ends 32 and 36 for clamping around the bowstring 124 , tapering to a minimum thickness at the arcuate portion 28 to enable release aid engagement. The arcuate portion 28 is also radiused on both edges 52 and 54 to approximate the cross-sectional profile of a bowstring for proper release aid engagement therewith. The U-shaped member 20 is anodized for improved durability.

Two stainless steel fastening plates 80 and 90 hold the bowstring 124 within the bowstring receiving grooves 32 and 36 . Each fastening plate 80 and 90 has two threaded through holes 84 and 86 (and 94 and 96 ). A stainless steel flat head machine screw 102 , 104 , 106 , and 108 extends through each of the countersunk holes 42 , 44 , 46 , and 48 of the U-shaped member 20 , the bevelled portion of the screw heads being received within bevelled portion of the countersunk holes. The screws 102 , 104 , 106 , and 108 are also threadedly engaged with the threaded holes 84 , 86 , 94 , and 96 of the fastening plates 80 and 90 whereby clampedly retaining a bowstring 124 positioned within the bowstring receiving grooves 32 and 36 .

An alternate embodiment of the invention is shown in FIG. 7 . In such embodiment of the bow nock device 130 , the U-shaped member 134 is attachable to the bowstring for gripping by the release aid and for positioning a nocked end of the arrow between the ends thereof. The U-shaped member has a transverse bowstring receiving groove 136 formed on a first side of each end thereof. The U-shaped member additionally has internal facing protrusions 138 formed proximal to each end thereof co-pending with the end of the arrow for stabilizing the same. Each end of the U-shaped member further has a pair of threaded first holes 140 . Two oval washers 144 formed of an elastomeric material are provided for holding the bowstring within the bowstring receiving grooves. Each oval washer has two through second holes 146 .

Two back plates 150 with third holes 152 , 154 positioned over the second holes of the two washers are next provided. Each back plate has a lobe 156 positionable adjacent to the space between the ends of the U-shaped members. Each back plate has a circular hole 152 remote from the ends of the U-shaped members and an enlarged hole 154 in a FIG. 8 shaped configuration proximate to the ends of the U-shaped member to selectively position the size of the space between the ends of the U-shaped member. In this manner arrow nocks of various sizes may be accommodated.

As can be readily apparent from the foregoing, when taken in conjunction with FIGS. 7 , when the screws are located through the adjacent portions of the FIG. 8 shaped holes of both back plates the lobes of the back plates are most distant from each other to accommodate the largest size nocks of larger arrows. When the screws are located through the remote portions of such holes of both back plates, the lobes are closest to each other to accommodate the smallest nocks. When the screws are located through one adjacent hole of one back plate and one remote hole of the other back plate, nocks of intermediate sizes may be accommodated.

A machine screw extends through each portion of the second and third holes. The screws are also threadedly engaged with the threaded first holes of the U-shaped member. In this manner a bowstring positioned within the bowstring receiving grooves is clampedly retained.

The two fastening plates are concave on one side and convex on the other. During assembly of the nocking device, it is necessary to put the convex side against the bow string. This convex feature is substantial to the life or chafing of the bow string.

The nocking device is of a short design. The shorter the nocking device the less chance of the same hitting and damaging the cables on a compound bow. This also cuts down on the weight of the nocking device. Cutting weight is important since every grain decreases arrow speed.

The present invention is made to work with most release aids including a caliper. Further, the clamping design of this device allows it to easily be moved to different locations on the bow string without damage to the device. Once the screws are tightened it will not move. In addition, this device also repeatedly aligns the shooter's peep sight.

As to the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.

With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.

Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention. Inasmuch as the present disclosure includes that contained in the appended claims as well as that of the foregoing description. Although this invention has been described in its preferred forms with a certain degree of particularity, it is understood that the present disclosure of the preferred form has been made only by way of example and numerous changes in the details of construction and combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention.
