Abstract
A bowstring release device for archery has a barrel with a notch at its distal end, and a pivotally mounted bail at the barrel distal end with a cam surface and a finger that projects across the notch to retain the bowstring. A release pin is slidably fitted in the barrel, and has a nose that is biased distally against the bail cam surface. The release pin has front and back cutouts that are axially spaced on the pin. A two part trigger assembly has a back trigger section and a front trigger section that are pivotally mounted on to the barrel, with the back and front sections each having an engaging tooth or sear to fit into a respective one of the release pin recess. The span between the trigger teeth is greater than the span between the two recess. The release is actuated by first pulling back on the trigger, and then gradually relaxing the finger pressure until both of the latch teeth are disengaged from the release pin.
