Toy mechanical hand with gripping fingers - has flexible strap passing through each hinged, hollow finger section to movable rod causing fingers to curl when lever is pulled

摘要

The mechanical hand amusement device consists of a movable grip joined by a rod, which extends through a tubular arm 10, to a hand member (16) which has a fixed thumb (22) and four finger members (24) which bend inward when the grip is squeezed. Each finger includes three hollow segments (26, 28, 30) which are joined by flexible hinges (32, 34) at the tops. A flexible strap (74) which is anchored within the fingertip segment runs along the bottoms. The strap extending through each of the fingers is coupled to the rod so that a portion of the strap is retracted into the hand member when the grip is squeezed. The forces move the finger inward in a grasping motion.
