ABSTRACT:
The bow string release has a body having a notch receiving a string which is retained by a pivoted sear capturing the string. The body is connected to a handle. A thrust bearing is located between the body and the handle, allowing the body and the handle to rotate relative to one another. A spring loaded plunger latches the sear to retain the string until the plunger is moved back by a trigger pivotally connected to the handle. A spring is compressed between the plunger head and a seat which can be adjusted to alter the trigger pull force. The trigger stroke is adjusted by the screw in the trigger adjustably engaging the hole in the wall of the release handle. Another embodiment has provision for triggering the release of a spring loaded piston which strikes the plunger to release the sear. A further embodiment uses a small solenoid in the handle to move the plunger to release the sear.
