Abstract
An archery bow lock mechanism allows a compound bow to be locked in the fully drawn position and released by the archer upon the application of a small amount of additional draw tension. The device utilizes a pair of pawl and ratchet members which approach each other and engage when the bow is drawn. Upon release of the drawstring the cam and ratchet members, which may be in the form of a ball and triangular ratchet, respectively, located on the bow cables, remain engaged, the ball being maintained in contact with a concave face of the ratchet by drawstring tension. Additional tension on the bow string disengages the pawl and ratchet, allowing the bow to be fired. Alternative positions for the ratchet and pawl members are available.
