Abstract:
A bowler's multi-stage wrist, hand and finger control device, comprising:(a) a hand plate with a ventral surface adapted to conform with a back of a bowler's hand and a dorsal surface; (b) a forearm plate with a ventral surface adapted to conform with a bowler's forearm and a dorsal surface; (c) a dual stage quick release automatic return hinge system which includes a hinge arm attached to the dorsal surface of the hand plate, a hinge base anvil attached to the dorsal surface of the forearm plate, and a release lever pivotally linking the hinge arm and the hinge base anvil such that the dual stage quick release automatic return hinge angularly disposes the hand plate and the forearm plate to each other at one or the other of two angles in a plane generally perpendicular to the dorsal surfaces of the hand plate and forearm plate depending on the corresponding position of the release lever.
