Abstract

An athletic accessory, which serves to permit an athlete normally to bend a jointed limb at will, but, at a critical time, to lock the limb in a fully extended, straight position, such as a bowler's arm during delivery of the ball, comprises two rigid members, a pivot for pivotally connecting the rigid members, supports and straps for attaching the rigid members to the upper and lower limb members of a jointed limb with the pivotal connection coincident with the joint, a sleeve for locking the rigid members together in a straight line, and an internal spring for governing the operation of the locking sleeve to cause the same to lock the rigid members and thus the user's limb in a straight line at the critical time in the athletic endeavor.
