Abstract

A diving mask includes a faceplate secured to a frame, a flexible skirt having a partition delimiting an upper viewing chamber from a lower breathing chamber, a snorkel having an inlet channel for inhaled air and at least one escape channel for exhaled air, the snorkel being a continuation of the upper part of the frame, the inlet channel for inhaled air leading into the upper chamber, whilst the first escape channel for exhaled air communicates with the lower chamber. The frame is rigid and inside the frame there is arranged at least one first inner duct for exhaled air having an upper end leading into the escape channel for exhaled air, and a lower end in fluid communication with the lower chamber.

First claim

The invention claimed is:

1. A water-sport mask comprising:
a rigid frame;
a faceplate surrounded by the rigid frame;
a flexible skirt mounted on the rigid frame, the flexible skirt comprising a partition delimiting an upper chamber and a lower chamber, the partition being arranged to bear upon the top of a user's nose when the water-sport mask is worn by the user so that the user's mouth and nose are positioned within the lower chamber, the partition having at least one passageway arranged to allow circulation of air from the upper chamber to the lower chamber during an inhalation phase;
a conduit having an inlet channel enabling entry of ambient air and a first escape channel enabling exit of exhaust air, the conduit extending at an upper part of the rigid frame, the inlet channel being in fluid communication with the upper chamber, and the first escape channel being in fluid communication with the lower chamber, the rigid frame comprising at least one first duct, the first duct having an upper end opening into the first escape channel, and a lower end opening into the lower chamber.

2. The water-sport mask according to claim 1 , wherein the flexible skirt also comprises at least one first coupling sleeve projecting from a first side edge of the flexible skirt, said at least one first coupling sleeve being in fluid connection with said at least one first duct for exhaust air.

3. The water-sport mask according to claim 1 , wherein the rigid frame comprises one or more ribs in contact with at least a portion of the flexible skirt.

4. The water-sport mask according to claim 1 , wherein the rigid frame comprises an outer portion, the flexible skirt being arranged between the faceplate and the outer portion of the rigid frame.

5. The water-sport mask according to claim 4 , wherein the rigid frame comprises one or more ribs, the flexible skirt being arranged between the outer portion of the rigid frame and the faceplate and in contact with at least a portion of the one or more ribs to prevent slippage of the flexible skirt.

6. The water-sport mask according to claim 1 , wherein the rigid frame comprises an outer portion, a lower portion of the outer portion of the rigid frame comprising a first element and a second element which are attached to one another to form the lower portion of the outer portion of the rigid frame.

7. The water-sport mask according to claim 2 , wherein the flexible skirt has a peripheral sealing lip arranged to bear against the user's face when the water-sport mask is worn by the user, said at least one first coupling sleeve flanking said peripheral sealing lip.

8. The water-sport mask according to claim 1 , wherein the partition forms one and the same part with the flexible skirt.

9. The water-sport mask according to claim 1 , wherein the conduit further comprises a second escape channel enabling exit of exhaust air, the second escape channel being in fluid communication with the lower chamber, the rigid frame further comprising a second duct, the second duct having an upper end opening into the second escape channel, and a lower end opening into the lower chamber.

10. The water-sport mask according to claim 9 , wherein the flexible skirt also comprises a first and a second coupling sleeves projecting respectively from a first and a second side edges of the flexible skirt, said first and second coupling sleeves being in fluid connection respectively with said first and second ducts for exhaust air.

11. The water-sport mask according to claim 9 , wherein the inlet channel is separated from the first and second escape channels via two longitudinal walls.

12. The water-sport mask according to claim 1 , wherein the conduit has an upper part provided with an air-permeable cage, the conduit also comprising a float movable within said cage, said float being arranged such that when the conduit is submerged in the water the float is caused to move so that float closes the conduit intake.

13. The water-sport mask according to claim 12 , wherein the float has an upper end provided with a shape acting as a shut-off device.

14. The water-sport mask according to claim 13 , wherein the conduit further comprises a plate comprising:
a main orifice communicating with the intake of the conduit; an inlet orifice communicating with the inlet of the inlet channel;
at least one first outlet orifice communicating with the outlet of the first escape channel;
a first check valve arranged to close the inlet orifice during an exhalation phase;
a second check valve arranged to close the first outlet orifice during an inhalation phase; the conduit further comprising a fluid communication chamber configured to provide fluid communication between the main orifice, the inlet orifice and the first outlet orifice.

15. The water-sport mask according to claim 14 , wherein the conduit comprises a body having a lower end and an upper end, the inlet channel and the first escape channel extending inside the body between the lower end and the upper end, and the fluid communication chamber being arranged in a cap sealingly attached to the upper end of the body.

16. The water-sport mask according to claim 1 , wherein the conduit is removable or can be tilted.

17. The water-sport mask according to claim 1 , wherein it further comprises an elastic retaining strap which extends between an upper portion of the rigid frame and a lower portion of the rigid frame.

18. The water-sport mask according to claim 17 , wherein the elastic strap comprises at least one link point with one or other of the lower or upper portions of the rigid frame, said link point being formed by the cooperation between one folded end of the elastic strap with a slot formed in the lower or upper portion of the rigid frame.

19. The water-sport mask according to claim 18 , wherein the elastic strap comprises two upper link points with the upper portion of the rigid frame, and two lower link points with the lower portion of the rigid frame.

20. The water-sport mask according to claim 1 , wherein it further comprises a purge valve positioned in the lower chamber to evacuate liquid to outside the water-sport mask.

21. The water-sport mask according to claim 1 , wherein the partition comprises a fold forming a lip.

22. The water-sport mask according to claim 1 , wherein the passageway of the partition comprises a check valve arranged to allow circulation of ambient air directed solely from the upper chamber to the lower chamber during an inhalation phase.

23. A water-sport mask comprising:
a rigid frame;
a faceplate surrounded by the rigid frame;
a flexible skirt mounted on the rigid frame, the flexible skirt comprising a partition delimiting an upper chamber and a lower chamber, the partition being arranged to bear upon the top of a user's nose when the water-sport mask is worn by the user so that the user's mouth and nose are positioned within the lower chamber, the partition having at least one passageway arranged to allow circulation of air from the upper chamber to the lower chamber during an inhalation phase;
a conduit having an inlet channel enabling entry of ambient air and a first escape channel enabling exit of exhaust air, the conduit extending at an upper part of the rigid frame, the inlet channel being in fluid communication with the upper chamber, and the first escape channel being in fluid communication with the lower chamber via a first duct, the first duct having an upper end opening into the escape cha
