Secure deflation valve

摘要

An inflatable shoe with a deflation valve (4) designed to limit inadvertent operation of the valve and thereby limit inadvertent deflation of the shoe. The deflation valve has a shortened plunger (27), a collar (25) to prevent tilt of the plunger, and a conformable ring (33) on the valve face. The plunger is provided with a groove sized and dimensioned to partially receive the inner surface of the ring.
