ABSTRACT:
This invention is that of a Bowstring Release Mechanism that is used in Archery for drawing the bowstring back and then releasing same to propel the arrow in its flight to the target. The mechanism is released by the use of a trigger, which is adjustable, and features a sear that aids in reducing applied force, resulting in an easier trigger pull. It includes the use of a flexible rope loop that is looped around the bowstring and held by a rotary holding member, which is locked by a sear. The sear is locked by a sliding trigger, which, when actuated, will free the sear and the holding member, allowing the loop to escape. The bowstring is then freed to propel the arrow.
