Description

Field of the Invention

[0001] The present invention relates to the field of masks for practicing water activities, in particular for diving and / or snorkeling. Background Art

[0002] Snorkeling allows observing the seabed while swimming on the water surface. Therefore, a snorkeler must be able to keep their head underwater while breathing.

[0003] Generally, a snorkeler is equipped with a mask for vision and a snorkel for breathing. The snorkel consists of a tube, the lower end of which is provided with a mouthpiece that is received in the user's mouth, and the upper end of which allows the entry of fresh air and the discharge of exhaled air.

[0004] As is well known, this equipment has many drawbacks. First, since breathing through the mouth is unnatural, some people have difficulty breathing through the mouth with a snorkel. Another drawback is that it is impossible to speak underwater when there is a snorkel in the mouth.

[0005] Another drawback related to the use of the mask is that the inner wall of the visor usually easily fogs up, which hinders good visibility and forces the user to regularly clean their mask. The fog appears because the user's nose exhales air into the vision chamber located between the visor and the user's eyes, and usually because any hot air generated in the vision chamber is not renewed by fresh air.

[0006] In addition, using this mask-snorkel device is not very comfortable.

[0007] To overcome this drawback, document FR 3 020 620 B1 proposes a diving mask that allows breathing through the nose and mouth.

[0008] However, this improved mask-snorkel does not allow the user to compensate for pressure during a depth descent. To perform this operation, it is necessary to pinch the nose to close the nostrils and balance the pressure in each ear (especially between the outer ear and the middle ear of a given ear). This operation is also known as the Valsalva maneuver.

[0009] Therefore, there is a need for a mask-snorkel that allows uniform breathing through the nose and / or mouth, prevents fogging in the vision compartment, and allows the operation of balancing the pressure in each ear for the user as many times as needed.

[0010] There is also a need for a lightweight, easy-to-wear-on-the-user's-face and comfortable mask-snorkel.

[0011] Thus, WO 2019 / 122786 relates to a mask for diving and / or snorkeling, which includes a flexible outer nasal insert engaged with goggles and a flexible inner nasal insert substantially superposed with the flexible outer nasal insert. The flexible inner nasal insert is connected to a flexible skirt. Thus, the user's nose is located in two superposed nasal housings. Depending on the morphology of the user's face, this superposition reduces the intuitiveness and accuracy of clamping, because the superposed thickness of both the external insert and the internal insert results in a greater distance between the hand of the user performing the Valsalva maneuver and their nose. In addition, the user may have lower sensitivity to touch. Depending on the morphology of the face, if the inner nasal insert contacts the nostrils during inhalation or under the action of the pressure exerted by water, this superposition will impede breathing. In fact, the pressure exerted by water will cause the outer nasal insert to deform, which also causes the inner nasal insert to deform.

[0012] It is also known that masks include a single flexible nasal insert arranged in goggles. These flexible inserts are not comfortable because, depending on the morphology of the user's face, it is difficult for the latter to clamp their nose. In fact, the travel of clamping the nose is too large, which causes proprioceptive problems and is particularly annoying when practicing snorkeling because clamping the nose must be intuitively felt. In addition, this type of mask has sealing problems between the visual cavity and the breathing cavity, thus increasing the risk of fog formation and CO2 accumulation inside the mask.

[0013] Therefore, there is a need for a mask that allows snorkeling and / or diving exercises, allows balancing the pressure at the ears by clamping the nose, has improved proprioception, is suitable for various face morphologies, is comfortable and prevents fog formation or CO2 accumulation inside the mask. Summary of the Utility Model

[0014] The utility model overcomes all or part of the above problems because it relates to a snorkeling or diving mask, including:

[0015] - Goggles and a flexible skirt, the flexible skirt including a partition wall separating a lower breathing cavity from an upper visual cavity, the partition wall being arranged to rest above the user's nose, such that the user's nose and mouth are located in the lower breathing cavity, while the user's eyes are located in the upper visual cavity,

[0016] - The goggles include a nasal through-hole, and

[0017] - The mask includes a flexible and deformable nasal insert configured to allow clamping of the user's nose, the nasal insert being mounted on the nasal through-hole.

[0018] Advantageously, the mask includes a thin portion connected to the partition wall, the thin portion being fixed to the goggles in at least one peripheral region of the nasal through-hole.

[0019] Advantageously, the thin part is fixed to the upper part of the goggles facing the visual cavity.

[0020] Advantageously, the thin part is fixed to the goggles within the visual cavity.

[0021] Advantageously, the thin part enables the partition wall of the skirt to be closer to the goggles. The available space in the breathing cavity is thus optimized, which can improve comfort and the proprioception of clamping the nose.

[0022] In addition, this arrangement can improve the seal between the visual cavity and the breathing cavity.

[0023] This arrangement can also optimize the amount of air present in the visual cavity and the amount of air present in the breathing cavity, especially to minimize these amounts. In fact, when the face mask is used for diving, the amount of air between the user's face and the face mask tends to exert a thrust opposite to the immersion and descent of the user. Therefore, it is necessary to reduce this dead volume while facilitating access to the nose, thus facilitating the immersion of the user's head in water while maintaining their comfort.

[0024] Face mask

[0025] Advantageously, the face mask is configured to include one or more air circulation passages, especially one or more inhaled air circulation channels and / or one or more exhaled air circulation channels.

[0031] Preferably, the face mask includes an exhaled air discharge port provided on the left or right side of the face mask and / or an exhaled air discharge port provided on the upper part of the face mask.

The right auxiliary wing 132 and the left auxiliary wing 134 are joined together at the auxiliary top 133.

[0186] Advantageously, the goggles 20 include a right peripheral region 20d adjacent to the right edge 70d of the nose through-hole 70, and a left peripheral region 20c adjacent to the left edge 70c of the nose through-hole 70. Particularly, the left peripheral region 20c and the right peripheral region 20d are joined together at the top 23. Preferably, the right edge 70d and the left edge 70c are joined together at the top 72. Advantageously, the nose through-hole 70 includes a lower edge 70b, and the lower edge 70b is particularly slightly curved, and the right edge 70d and the left edge 70c are connected together particularly via the joining portions 70e and 70f. Particularly, the lower peripheral region 20e is adjacent to the lower edge 70b of the nose through-hole 70, and particularly the lower peripheral region 20e is slightly curved.

[0187] Advantageously, using the fixing device 140, the right auxiliary wing 132 of the thin portion 130 (particularly in a sealed manner) is fixed to the right peripheral region 20d along the inner surface 24 of the goggles 20, and the left auxiliary wing 134 of the thin portion 130 (particularly in a sealed manner) is fixed to the left peripheral region 20c along the inner surface 24 of the goggles 20.

[0188] Advantageously, the mask 10 includes a fixing device 140 configured to clamp and fix the thin portion 130 against the inner surface 24 of the goggles 20.

[0189] Particularly, the fixing device 140 includes a first set of lugs 142 (such as three or four lugs) protruding from the inner surface 24 of the goggles 20 into the left peripheral region 20c, and a second set of lugs 144 (such as three or four lugs) protruding from the inner surface 24 of the goggles 20 into the right peripheral region 20d. The fixing device 140 further includes a clamping member 146, and the overall shape of the clamping member 146 corresponds to the shape of the thin portion 130 (or the sealing lip).

[0192] Preferably, the thin portion 130 is disposed against the outer surface 24 of the goggles 20 such that the first set of lugs 142 and the second set of lugs 144 pass through the corresponding first set of through - holes 135 and second set of through - holes 136 of the thin portion 130, and then the first set of through - holes 147 and the second set of through - holes 148 of the clamping member 146 are also forced to pass through the first set of lugs 142 and the second set of lugs 144. Preferably, the diameter of the lugs 142, 144 is slightly larger than the diameter of the through - holes 147 and 148 of the clamping member 146, such that the clamping member 146 is forced to pass through the lugs and remains in place without any other fixing means. The advantage of this assembly method is that it is more water - resistant, especially to salt water, compared to, for example, fixing by adhesion.

[0193] Advantageously, the nose insert 80 is overmolded on the right edge, left edge, and lower edge (70c, 70d, and 70b) of the nose through - hole 70, and optionally on the joint portions 70e and 70f. As can be seen, for example, in Figure 7 the right edge 70d of the nose through - hole 70 includes an L - shaped welding area that receives the corresponding right edge 80d of the nose insert 80.

[0194] As Figure 2 shown, the goggles 20 include a substantially flat upper region 28, especially passing through a plane (Pv). Preferably, the plane (Pv) is substantially parallel to the front plane (Pf).

[0195] Preferably, the nose insert 80 includes a nose distal end 86, and the distance Din between the outer surface 22 of the upper visual region 28 and the nose distal end 86 is greater than or equal to 10 mm, preferably greater than or equal to 18 mm.

[0196] Preferably, the nose receiving housing 81 includes a nose bridge portion 85 having a length Lin, especially Lin is greater than or equal to 18 mm and less than or equal to 23 mm, preferably approximately 21.80 mm.

[0197] Preferably, the distance Dinc between the nose distal end 86 and the upper top 35b of the right free edge 35a of the right main wing 35 (as Figure 7 shown) is greater than or equal to 30 mm, especially approximately 47 mm.

[0198] Preferably, the distance Dincr between the vertical plane P1 passing through the upper top 37 of the base of the folding region of the right main wing 35 passing through the partition wall 40 and the vertical plane P20 passing through the nasal distal end 86 of the nasal receiving housing of the nasal insert 80 (as Figure 7 shown) is in the range of 30 mm to 40 mm, particularly approximately 35.1 mm. The vertical plane is substantially parallel to the front plane Pf.

[0199] Preferably, the nasal insert 80 includes a right recess 83 and a left recess 84 provided on both sides of the nasal receiving housing 81, and the width Linr separating the right base of the right recess 83 and the left base of the left recess 84 (as Figure 5 shown) is greater than or equal to 35 mm and less than or equal to 45 mm, particularly approximately 41.5 mm.

[0200] Preferably, the nasal insert 80 includes a flexible material having a Shore A hardness less than or equal to 90, preferably a Shore A hardness greater than or equal to 50.

[0201] Preferably, the nasal insert 80 includes Figure 7 the wall thickness ep as shown, which is less than or equal to 3 mm, particularly between 0.3 mm and 3 mm.

[0202] Advantageously, the distance L between the reattachment point 160 of the left nasal wall 81c of the housing 81 and the goggles 20 (particularly the left edge 70c of the nasal through-hole 70) and the reattachment point 170 of the right nasal wall 81d of the housing 81 and the goggles 20 (particularly the right edge 70d of the nasal through-hole 70) PR is greater than or equal to 25 mm and less than or equal to 35 mm, preferably approximately 31.3 mm.

[0203] Advantageously, as Figure 5 shown, the right nasal wall 81d and the left nasal wall 81c of the nasal receiving housing 81 are convex, particularly they diverge towards the base 81b of the nasal receiving housing 81. The mask 10 may further include a detachable appliance for fixing the mask to the user's head, such as one or more elastic bands connected to the body 90 by passing through one or several rings provided in the body 90.

[0204] In operation, the user places the mask 10 on the face and secures it using the securing means. The oval body 110 matches the periphery of the face, with the user's eyes in the vision cavity 50 and the user's nose and mouth in the breathing cavity 60. The dividing wall 40 is supported on the bridge of the nose, and the user's nose faces directly towards the inner surface of the nose insert 80 for exhalation. The thin portion 130, which is sealingly connected to the dividing wall 40, is fixed to the inner surface 24 of the goggles 20, particularly in the peripheral regions (20c, 20d) of the nose through-hole 70 facing the breathing cavity 50, thus improving the seal between the vision cavity 50 and the breathing cavity 60. Additionally, the dividing wall 40 is closer to the goggles 20, which allows for the optimization of the dead space and thus the air volume available in the breathing and vision cavities, particularly reducing the dead space without compromising comfort to facilitate submersion.

[0205] Furthermore, the combination of the dimensions Linr, Lpr, Dinc, Dincr, Lin, and Din enables an improved proprioception to optimize the volumes in the vision and breathing cavities (50, 60). The nostrils are not pressed against the left and right nasal walls of the nose receiving housing 81, and a certain amount of air circulates around the nose placed in the housing 81 and the breathing cavity 60, so that fresh air from the breathing tube can be inhaled through the nose, pass through the vision cavity 50, and then enter the breathing cavity 60. The air exhaled through the nose enters the exhaust passage, which in this particular (non-limiting) example is provided along the periphery of the lower part 20b of the goggles 20 and cooperates with the flexible skirt 30 for sealing. These exhaust channels (not shown) extend at least partially on the left and right sides of the body 90, and their upper ends open at the level of the upper part 92 of the body 90 and are fluidly connected to the exhaust ducts of the breathing tube 120. The exhaust channels can also open on the left and right sides of the body 90. In this case, the breathing tube only allows fresh air to be inhaled during re-inhalation.
