Title (EN) BREATHING HOSE FOR A DIVING BREATHING DEVICE
(FR) TUBA POUR APPAREIL RESPIRATOIRE DE PLONGEE
Abstract: front page image
(EN)When viewed in a cross section taken along an axial direction (50a), a breathing hose (50) for a diving breathing device comprises a circumferential wall (51) constituted by an outwardly projecting thicker portions (52) flat on an internal circumferential surface thereof and thinner portions (53) bent inwardly at a small curvature which are disposed in an alternate fashion. Since the internal circumferential surface (51a) is practically a flat surface, there is no risk of causing a sanitary problem as is encountered with a bellows hose where dirty matters accumulate in recessed portions to permet propagation of various germs. In addition, thinner portions provide flexibility required for a breathing hose.
(FR)Cette invention concerne un tuba (50) pour appareil respiratoire de plongée, lequel tuba, lorsque l'on regarde sa section dans le sens longitudinal (50a), comprend une paroi circonférentielle (51) comportant des parties épaisses orientées vers l'extérieur (52) et planes à la surface circonférentielle interne de ladite paroi, ainsi que des parties minces repliées vers l'intérieur selon une faible courbure, lesdites parties étant disposées de manière alternée. Etant donné que la surface circonférentielle interne (51a) est pratiquement plane, il n'y a aucun risque de problème sanitaire comme on en voit dans des tubas à soufflet où des matières sales s'accumulent dans les parties renfoncement et entraînent la propagation de germes divers. Les parties fines assurent en outre la flexion nécessaire du tuba.
