Prehensile Foot Restraint

Abstract

Proposed prehensile foot restraint enables such workers as astronauts and divers to maintain fixed positions in zero gravity or in buoyancy with minimal effort. With foot restraint worker devotes attention fully to task at hand, with little concern about holding on to supporting structure. Claw near toe of shoe grips rail. Wearer uses flexible shaft, first to lock claw tightly on bar; then, when work is done, to open claw. Underwater or in space, device boosts productivity.
