A bowstring release system for crossbows having a preferably ball-shaped nocking member mounted on a bowstring for engaging a nock portion of an arrow. Upper and lower surfaces of the bowstring release system are positioned near the rear of the crossbow, and move between open and closed positions relative to each other to vary the size of a release passage defined therebetween. In the closed position, the upper and lower catch surfaces are positioned sufficiently near each other to block the nocking member from passing through the release passage. And in the open position, the upper and lower catch surfaces are sufficiently separated to allow passage of the nocking member for propelling the arrow. When the bowstring is cocked, a locking mechanism actuates one or both of the upper and lower catch surfaces to the closed position, and a trigger mechanism releases the locking mechanism and actuates either one or both of the upper and lower catch surfaces to the open position.

1. A bowstring release mechanism for crossbows having a bow horizontally mounted at a forward portion of a crossbow stock, said bow having a bowstring with a nocking member mounted thereon for releasably engaging a nock portion of an arrow, said bowstring release mechanism comprising:upper and lower catch surfaces positioned at a rearward portion of said crossbow stock in vertical relation to each other and having a release passage defined therebetween; and actuating means for vertically moving said upper and lower catch surfaces relative to each other between a closed position wherein said upper and lower catch surfaces block passage of a cocked nocking member through said release passage without seizing said cocked nocking member, and an open position wherein said cocked nocking member passes through said release passage to propel said arrow via said nock portion.
