ABSTRACT:
The subject invention provides a bow string release mechanism over and under bow string retaining jaws and an axial adjustment mechanism for altering the distance of the jaws from a wrist strap. The release mechanism generally comprises a release mechanism, a wrist strap, and a rotatable shaft assembly joining the release mechanism and the wrist strap, wherein the axial distance between release mechanism and the wrist strap can be adjusted by axial rotation of the shaft assembly. The release mechanism comprises a trigger mechanism, a body in which the trigger mechanism is mounted and actuated and a sear head attached to the body and actuable by the trigger mechanism. The sear head has a first fixed over and under sear element and a second pivotally attached over and under sear element, movable relative to the first fixed sear element, into and out of engagement therewith upon actuation of the trigger mechanism. The rotatable shaft assembly comprises a threaded bore at one end of a shaft to engage an externally threaded adjusting rod attached to the wrist strap. The shaft is attached at its other end, via a ball and socket coupling, to the release mechanism. The ball and socket coupling permits the release mechanism to freely pivot about the end of the shaft assembly. The threaded bore of the shaft permits the distance between the release mechanism and the strap to be rotatingly adjusted to accommodate various hand sizes.
