Abstract

A bowstring release with a fixed jaw and a single movable jaw is controlled by a trigger mechanism to provide enhanced accuracy. The bowstring release mechanism is adapted to rotate about its longitudinal axis to readily align the jaws with a bowstring, and the bowstring release is further attached to a wrist strap by means of a ring or attachment plate having two relatively straight sides engaged by leather tabs on the wrist strap. The straight sides and the leather tabs control and define the location of the ring thereby removing positional variances of the point of force transmission between the wrist strap and the bowstring release device and eliminate at least some variations which will affect consistent bowstring draw and release. The use of both a single fixed jaw and a movable jaw improves the accuracy and the smoothness with which the bowstring is released by stabilizing the bowstring during the initial portions of its flight after release. The release is connected to the wrist strap by an adjustable rotational connection which may be assembled to custom fit the release position to the wrist of the user. The connection permits a selection of one of several lengths or distances from the wrist strap to the bowstring release jaws.

Claims

1. An adjustable bowstring release device comprising:

a pair of jaws for engaging and releasing an archery bowstring;

a body supporting said jaws for cooperation in engaging and releasing said bowstring;

a control trigger cooperatively associated with at least one of said jaws;

said body comprised of a hollow portion forming a tube, said tube defining a plurality of apertures extending through a wall of said tube and spaced along a length of said tube;

a wrist attachment assembly;

an interconnection member coupled to said wrist attachment assembly and complimenting said tube, said interconnection member defining at least a hole therethrough, said hole alignable with one of said apertures in said tube;

a force transmission member engaged with and extending through said hole and one of said apertures, whereby selection of said aperture into which said force transmission member is engaged establishes a distance from said wrist attachment assembly to said control trigger and said jaws.

2. The adjustable bowstring release device of claim 1 wherein said body comprises a plurality of pairs of apertures, each pair of said aperture disposed with each aperture across said tube, and each said pair spaced from said others of said pairs along said body tube portion.

3. The adjustable bowstring release device of claim 2 wherein one of each said pairs of apertures comprises threads and said force transmission member is a screw inserted into and threadedly engaged with said threaded aperture.

4. The adjustable bowstring release device of claim 3 wherein said interconnection member comprises a first portion coupled to said wrist attachment assembly and a second portion pivotally coupled with respect to said first portion, said second portion defining said hole.

5. The adjustable bowstring release device of claim 4 wherein said first portion of said interconnection member has a longitudinal axis and said second portion is pivotable about said axis.

6. The adjustable bowstring release device of claim 5 wherein said second portion of said interconnection member comprises a cup shaped member and is coupled to said first portion by a fastener, said cup disposed coaxial with said first portion.

7. The adjustable bowstring release device of claim 1 wherein said interconnection member comprises a first portion coupled to said wrist attachment assembly and a second portion pivotally coupled with respect to said first portion, said second portion defining said hole.

8. The adjustable bowstring release device of claim 7 wherein said first portion of said interconnection member has a longitudinal axis and said second portion is pivotable about said axis.

9. The adjustable bowstring release device of claim 8 wherein said second portion of said interconnection member comprises a cup shaped member and is coupled to said first portion by a fastener, said cup disposed coaxial with said first portion.

10. The adjustable bowstring release device of claim 9 wherein said apertures comprise threads and said force transmission member is a screw inserted into and threadedly engaged with said threaded aperture.

11. An adjustable bowstring release device comprising:

a pair of jaws for engaging and releasing an archery bowstring;

a body supporting said jaws for cooperation in engaging and releasing said bowstring;

a control trigger cooperatively associated with at least one of said jaws;

a wrist attachment assembly;

an interconnection member coupled to said wrist attachment assembly;

said body and said interconnection member complimenting each other and forming a rotational connection between said body and said interconnection member, a hole extending through one of said body and said interconnection member and a plurality of apertures extending through the other of said body and said interconnection member and spaced apart thereon, said hole and said apertures alignable;

a force transmission member engaged with and extending through said hole and one of said apertures, whereby selection of said aperture into which said force transmission member is engaged establishes a distance from said wrist attachment assembly to said control trigger and said jaws.
