Abstract
For holding a bowler's arm rigid after it is straightened, an automatically locking hinge acts between an upper strap that is worn on the upper arm and a lower strap that is worn on the forearm. The hinge has an upper hinge structure which presents a circular peripheral surface with a detent recess at one circumferential location. The hinge has a lower hinge structure with a spring-pressed locking element that snaps into the detent recess when the arm is straightened.
