Embodiment Construction

[0051] figure 1 An exemplary embodiment of a diving mask 1 according to the invention is represented. The diving mask 1 comprises a body 2 and a snorkel 4 mounted on the body 2, preferably removably mounted on the body.

[0052] The body 2 notably comprises a frame 6 , goggles 8 and a flexible skirt 10 .

[0053] The frame 6 is generally oval in shape, has an upper part 6a and a lower part 6b, and in use forms a banding (joint) around the user's face.

[0054] The frame 6 may also comprise a first duct (not shown) for exhaled air, enabling at least part of the air exhaled by the user to be conveyed to the vent tube 4, in particular from the lower chamber defined hereinafter to the vent tube and a first duct (not shown) for the inhaled air, enabling at least partly conveying the inhaled air from the ventilation tube 4 to the user, in particular to the upper chamber defined below.

[0055] Finally, frame 6 includes slots 11 intended to receive one or more elastic straps (not ...

Abstract

The invention relates to a diving mask comprising a snorkel (4) with a valve (34), the valve (34) comprising: a valve port (38) intended to allow fluid, in particular air, to circulate between the outside of the snorkel and the inside of the snorkel, and a valve shutter element (40), for example a float, which can be moved between an open position in which the valve port (38) is open and a closed position in which the valve port (38) is closed by the valve shutter element (40), the mask also comprising a balancing means (46) for restricting a pressure difference between the inner pressure of the mask and the outer pressure, the balancing means (46) being configured to allow fluid to circulate between the outside of the mask and the inside of the mask when the mask is being worn by a user and the shutter element (40) is in the closed position.

Description

technical field [0001] The present invention relates to the field of diving masks, and in particular to masks for snorkeling. Background technique [0002] Typically, snorkelers are equipped with a mask for viewing and a snorkel for breathing. The vent consists of a tube whose lower end is provided with a buccal portion (buccal portion) which is received in the user's mouth, and whose upper end allows both the inhalation of fresh air and the exhalation of air. discharge. [0003] It is well known that such equipment has a number of drawbacks. First, because breathing through the mouth is unnatural, some people find it difficult to breathe through the mouth with a snorkel. Another drawback is that it cannot speak underwater when the snorkel is in its mouth. [0004] Additionally, using such a mask-snorkel arrangement is not very comfortable. In order to overcome this drawback, document FR 3 020620 proposes a diving mask that allows breathing through the nose and through ...
