Sail board frame harness - is articulated to strap fixed round wrist and fits into hand

摘要

The harness reduces the muscular fatigue of the arms when using a sail-board and consists of a hook (10) and a strap (11) fixed round the wrist. The hook is articulated to the strap on the internal side of the hand and is shaped to fit into the hollow of the hand when the fingers (8) are folded round the wishbone (4). The hook is a rectangular ring and one narrow extremity is articulated to the strap and the opposite extremity (13) is curved to fit partly round the wishbone.
