发明名称 Simplified apparatus for use in arm wrestling or wrist pulling contests
摘要 Apparatus for conducting arm wrestling (wrist pulling) contests between a pair of opposed contestants comprising a playing surface in which a lever arm is adapted for pivotal side-to-side motion. The opposed contestants each grip a laterally spaced portion of the lever arm in an attempt to force such to one side of its travel limit and against the opponent's urging. The ends of the lever arm are adapted to contact signal means extending above the playing surface at the opposite ends of the travel limit of such lever arm which are in turn activated upon contacting the lever arm so as to signal a contest winner.
