Abstract: A bowstring trigger includes a safety lock to prevent premature release of the arrow. Initially, the trigger is cocked by pushing the arrow onto the bowstring thereby causing a bowstring gripper lever to engage the bowstring. In this state, a safety lock lever under the influence of a bias spring moves into the normal path of the trigger lever thereby preventing it from releasing the release lever. A safety release guide string symmetrically attached to opposite sides of the bow handle is connected to the safety release lever and causes it to move out of engagement with the trigger lever when the bowstring is fully withdrawn. With the safety off, the archer can release the bowstring by pushing on the trigger lever with his or her thumb thereby causing the gripper release lever to disengage the bowstring gripper. The bowstring gripper moves forward under the influence of the bowstring and simultaneously releases the arrow in the direction of the target.
