ABSTRACT:
The improved archery bowstring release device of the invention includes a frame, a pair of opposable jaws pivotably connected to the front of the frame with the bowstring-retaining ends of the jaws at the front thereof and with the opposite or rear ends thereof defining a space when the front ends abut. A plunger with a specially configured head having a wider diameter at its front end is slideably disposed in the frame, the plunger head being urged forward into the space by a spring so as to keep the front ends of the jaws closed, trapping a bowstring therein. A trigger is secured to the plunger and enables the archer to urge the plunger rearward in the frame and out of the space so as to permit the front ends of the jaws to open and release the trapped bowstring. An adjustable stop may be provided to finely control the extent to which the head can be urged into the space and thus the extent of rearward movement of the trigger necessary to withdraw the head from the space. The configured head assures that opening of the front ends of the jaws during withdrawal of the head will be sudden and unexpected. An adjustable collar, usable on the archer's wrist or elbow, is attached to the frame by a cord to enable the archer to draw the bowstring by the release device. The device permits extremely accurate archery bow shooting.
