ABSTRACT:
Apparatus for aiding the drawing and releasing of a bowstring, including a flexible endless cord having a pair of end loops which snugly receive the bowstring, and an intermediate draw loop of predetermined size for snugly receiving and holding a bowstring draw pin. Expansible and contractible sleeves are mounted on the cord between the end loops and the draw loop, permitting portions of the endless cord to relatively move and expand the size of the draw loop to a greater predetermined size when the bow is drawn, and thus permit the escape of the draw pin. One aspect of the invention includes hand held bowstring draw mechanism pivotally mounting the draw pin for movement between a bowstring draw position and a bowstring release position and mechanism for selectively holding the draw pin in the draw position.
