Patent

CA 2357144

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

Il s'agit d'une chaussure gonflable avec valve de dégonflage conçue pour limiter l'ouverture inopinée de la valve et, donc, limiter le dégonflage non intentionnel de la chaussure. La valve de dégonflage est pourvue d'un piston court, d'un collet évitant le basculement du piston et d'un anneau concordant sur la surface de la valve. Le piston est pourvu d'une rainure de dimension et de taille telles qu'elle puisse recevoir partiellement la surface intérieure de l'anneau.
