ABSTRACT:
Bow string release for use by an archer with a bow and arrow for pulling a bow string through the center of the hand by engaging the bow string with an eyed string of the bow string release at a predetermined position for precise shooting of an arrow. The bow string release includes two degrees of freedoms with orthogonally positioned pivot points. The release mechanism is a threaded hook member in cooperating with an eyed string at one of the pivot points which captures the bow string. The pivoted hook-eyed string mounts on a plate which pivots about a wrist strap. The wrist strap including a roller clasp, positions over an archer s thumb, across the palm of his hand, and secures in position with a strap having a plurality of holes through the roller clasp. The bow string release is actuated by removing the thumb which results in pivoting of the hook-eyed string member such that the force of the bow string pivots the hook-eyed string about the pivot point for subsequent release of the eyed string thereby releasing the drawn bow string for flight of the arrow. An alternative embodiment includes a wrist strap having a threaded member secured at a forward position on the wrist strap for attachment of other bow string release structures.
