ABSTRACT:
A bowstring release assembly comprises a housing that receives the operative components that facilitate bowstring release motion. A gear assembly initiates and actuates the release motion. A rack and a pinion form the gear assembly. A trigger operates the rack to translate within the housing. The pinion is formed on a first portion of the peripheral surface of a rotary member which rotates in response to operation of the rack. A cam is formed on a second portion of the peripheral surface of the rotary member. The cam cooperates with a roller disposed on one end of a restraint assembly mounted on a pivot pin within the housing to allow bowstring release. A peg disposed on a second end of the restraint assembly engages the bowstring for restraint and pivots away upon actuation for release. A rope loop anchored to the housing may be provided to wrap around the bowstring and hook onto the peg for restraint.
