Definitions

  • the present disclosure relates to the field of diving masks, and in particular masks used for snorkeling.
  • the snorkeler equips himself with a mask for viewing, and a snorkel for breathing.
  • the snorkel is composed of a tube, the lower end of which is provided with a mouth portion which is housed in the mouth of the user, and an upper end allowing both the intake of fresh air and the expelling of exhaled air.
  • the document FR 3 020 620 B1 proposes a diving mask making it possible to breathe through the nose and the mouth.
  • this type of improved mask and tube does not allow the user to compensate for the pressure when he descends into the depths of the water. To perform this operation, it is necessary to pinch the nose in order to close the nostrils and balance the pressures on each of the ears (in particular between the outer ear and the middle ear of a given ear).
  • the present disclosure palliates the aforementioned problems in that it has for object a diving mask comprising:
  • the partition may be arranged to be supported above the nose of a user in such a way that the nose and mouth of the user are located in the lower chamber, while the eyes of the user are located in the upper chamber.
  • the faceplate is arranged so as to not cover the nose, and optionally the mouth of the user, so that the user can pinch his nose, by pinching the main housing of the main nasal part.
  • the snorkel is in fluid connection with the upper chamber.
  • the body may include a fresh air intake device which is in fluid communication with the snorkel and with the upper air chamber.
  • the upper edge of the main nasal part may comprise a projection having a setback, arranged such as to receive the lower edge of the upper part of the faceplate.
  • the upper edge of the main nasal part grips the upper or lower face, and the face edge of the lower edge of the upper part of the faceplate.
  • the setback may be L-shaped.
  • the upper edge of the main nasal part can alternatively comprise a U-shaped projection receiving the lower edge of the upper part of the faceplate.
  • the upper edge of the main nasal part may be engaged with the upper and lower faces, and the face edge of the lower edge of the upper part of the faceplate.
  • the flexible skirt may be attached to the faceplate.
  • the faceplate may be at least partly transparent.
  • the faceplate may have a transparent flat portion which is located facing the upper chamber.
  • the flexible skirt may comprise a sealing lip arranged to be supported by the face of the user.
  • the flexible skirt (and therefore said partition) and the main nasal part, and optionally the auxiliary nasal part defined below, may each be made of a polymer material, which materials can be different or identical (in their composition, their appearance (shapes, colors etc.), their mechanical properties (mechanical tensile strength, tensile elongation at break etc.)).
  • Said polymer material may have an elongation at break, for example tensile, greater than or equal to 100%, or for example greater than or equal to 300%, or for example greater than or equal to 400%.
  • the polymer material may be made of an elastomer.
  • the flexible skirt, the main nasal part, and optionally the auxiliary nasal part may thus be deformable and flexibly take the shape, on the one hand, of the face of the user, thus possibly improving his comfort, and on the other hand, of the rigid or semi-rigid parts of the mask which may improve the sealing.
  • the exhaled air expelling device may include a first exhaled air expelling channel which extends along one of the two lateral edges of the body, the flexible skirt having a first lateral part which covers the first exhaled air expelling channel.
  • the first and second exhaled air channels may extend on either side of the two lateral edges of the faceplate.
  • the exhaled air expelling device may include a second lateral part which covers the second exhaled air expelling channel.
  • the first exhaled air expelling channel, and optionally the second exhaled air expelling channel may (each) comprise two lateral walls and one back wall. Said walls may form a U shape in the cross section of said first channel, and optionally of said second channel.
  • the first channel, and optionally the second channel can thus be each composed of two adjacent ribs, which project from a first lateral edge of the faceplate, and optionally from a second lateral edge of the faceplate respectively.
  • the first exhaled air expelling channel, and optionally the second exhaled air expelling channel, can form a single part with the faceplate. Still preferably, both (sets of two) adjacent ribs form a single part with the faceplate.
  • the first exhaled air expelling channel and where applicable the second exhaled air expelling channel, can be a different part or parts of the faceplate, secured, removably or otherwise, to one of the two lateral edges (or to the two edges) of the faceplate.
  • Said part may have a U-shaped cross-section.
  • the first lateral part, and where applicable the second lateral part, of the skirt may include a lateral edge in which is engaged the first (or second) air expelling channel in order to prevent the water from entering the first (or second) air expelling channel.
  • the lateral edge of the skirt may include an upper wall and at least one lateral wall.
  • the skirt may include, two lateral walls. Said lateral wall (or walls) may flank the rib (or two ribs) of the first (or second) expelling channel while the upper wall may cover the first (or second) expelling channel in order to provide sealing.
  • Said lateral edge may be located on the outer periphery of the sealing lip of the skirt which is arranged to be supported by the face of the user.
  • the body of the mask may include a band that surrounds the faceplate.
  • the band may be rigid or semi-rigid.
  • the peripheral edge of the skirt may be clamped between the band and the first (or second) exhaled air expelling channel.
  • the first lateral part and/or the second lateral part of the skirt may be clamped between the band and the first (or second) exhaled air expelling channel. This may have the effect of preventing the peripheral edge of the skirt from uncoupling from the first (or second) exhaled air expelling channel.
  • the first exhaled air expelling channel, and optionally the second exhaled air expelling channel may comprise a lower end portion including at least one opening into the lower chamber, and optionally an upper end point in fluid connection with the snorkel.
  • the exhaled air expelling device may comprise a second exhaled air expelling channel equivalent to the first exhaled air expelling channel.

  • the first check valve 43 also includes a valve seat 144 arranged to cooperate with the flexible membrane 142 , the valve seat being incorporated into the faceplate 20 . In the closed position, the flexible membrane 142 is supported by the valve seat 144 to seal said at least one opening arranged in the first exhaled air expelling channel 81 .
  • the exhaled air expelling device 80 moreover comprises a second check valve 160 , similar to the first check valve 43 , which is arranged to permit a flow of exhaled directed from the lower chamber 50 toward the air duct 72 of the snorkel 70 during a phase of exhalation of the user.
  • the second check valve 160 operates like the first check valve 43 .
  • the flexible skirt 30 has first 51 and second 52 lateral parts arranged so as to cover in a sealed manner the first and second exhaled air expelling channels 81 and 82 .
  • the user disposes the mask 1 on his face, which mask can comprise attaching means such as elastic straps of adjustable length.
  • attaching means such as elastic straps of adjustable length.
  • the inhaled fresh air crosses the duct 72 of the snorkel 70 and comes out in the upper viewing chamber 45 then passes into the passage arranged by means of the check valve 55 in the partition 40 to come out in the lower breathing chamber 50 in which the nose and the mouth of the user are located.
  • the check valve 55 is configured to allow the inhaled air to travel from the viewing chamber 45 toward the breathing chamber 50 and prevent any return of exhaled air in the opposite direction.
  • the passage of air in the partition 40 is sealed so that the air is forced through the first and second air expelling channels 81 and 82 disposed along the lateral edges 2 and 3 of the body 10 , in particular disposed along the lateral edges of the faceplate 20 and closed in a sealed manner by the corresponding lateral edges of the flexible skirt 30 .
  • the first and second exhaled air expelling channels 81 and 82 are in fluid connection in their upper parts with the snorkel 70 , in particular with the single air duct 72 .
  • the exhaled air is therefore evacuated toward the snorkel 70 without passing through the upper viewing chamber 45 .
  • the user pinches his nose, by lodging his fingers in the recesses 31 and 32 of the main housing 16 .
  • the auxiliary housing 62 being nested into the main housing 16 , the pressure exerted on the main housing 16 is transmitted to the auxiliary housing 60 , which transmission is facilitated due to the protuberances 5 and 6 of the main housing pressing against the protuberances 90 and 91 of the auxiliary housing 60 .
  • the nesting together of the main 16 and auxiliary 62 housings facilitates the pinching of the nose.
  • the arrangement of the faceplate 20 in front of the mouth, along with the overmolding of the main nasal part 15 on the opening 4 , and its arrangement with respect to the auxiliary nasal part 60 allow the nasal parts 15 and 60 not to be located against the mouth of the user which facilitates breathing.
  • the main nasal part 15 being overmolded on the lower edge 21 a of the upper part 21 of the faceplate 20 on the one hand, and on the upper edge 22 a of the lower part 22 of the faceplate 20 on the other hand, and where applicable on the lateral edges 20 d of the faceplate 20 , there is no risk when the user handles it that it will detach from the faceplate 20 .
  • the mask 1 according to the disclosure thus makes it possible to combine the advantages of an anti-condensation mask allowing breathing interchangeably through the nose and mouth, while being able to balance the pressures on the ears.
