Abstract

In a first embodiment, a bilateral snorkel apparatus is shown. The bilateral snorkel consists of two tubes connected to a user's mouthpiece at one end and to each other at opposite ends at the back of the user's head. Lateral movement of the snorkel tubes is thus avoided by virtue of the increased rigidity of the tube arrangement. Lateral movement of the mask is also avoided by virtue of connecting the two tubes at the back of the user's head. In a second embodiment, a switchable mouth/nose breathing system is also disclosed. Switching between the mouth and nose is accomplished through a mouth operated hydraulic bladder which enables nose bladders/pads to close the user's nostrils. In a third embodiment, a hydraulically activated valve is illustrated for switching air circulation respectively between the mouth, the nose or for allowing combined mouth/nose breathing.

Claims2

Dependent claims

A diving face gear comprising:

a face mask having an enclosed nose covering;
a breathing tube connected to an air source;
a mouthpiece connected to said breathing tube;
a wind pipe tube connected to said nose covering and to said mouthpiece;
and switching means for selectively allowing or not allowing fluid connection through said wind pipe tube enabling a user either to breath through said mouthpiece and through said nose covering at the same time or to breath exclusively through said mouthpiece avoiding water entrance to said nose covering;
an actuator consisting of a water filled pair of bladders appended to said mouthpiece and designed to fit inside a user's mouth so that a user can depress said bladders with the teeth causing water to be expelled from said bladders or release teeth pressure causing water to enter said bladders;
a pipe connecting said bladders through said mouthpiece to a single external connection tube;
and nose clamping means controlled by said actuator.
