DETAILED DESCRIPTION

(16) FIGS. 1A and 1B show a diving mask 10 in accordance with the present disclosure.

(17) The diving mask comprises a body 12 for placing over the face of a user, with the body 12 presenting a top portion 14 and a bottom portion 16.

(18) From FIGS. 1A and 1B, it can be understood that the top portion 14 of the body 12 is for placing in the proximity of the user's forehead, whereas the bottom portion 16 of the body is for placing in the proximity of the user's chin.

(19) Furthermore, the diving mask 10 includes a snorkel 18 that extends the top portion 14 of the body 12.

(20) In this example, the snorkel 18 is mounted on the body 12 in removable manner.

(21) With reference to the exploded view of FIG. 2, it can be understood that the body 12 is constituted mainly by a faceplate 20 and a flexible skirt 22.

(22) The faceplate 20 is made of rigid material, e.g. of polycarbonate, while the flexible skirt 22 is made of flexible material, e.g. of silicone obtained by injecting liquid silicone rubber (LSR).

(23) The flexible skirt 22 is fastened to the faceplate.

(24) The body 12 also has a band 24 that is shaped to surround the face. The particular function of the band 24 is to fasten the flexible skirt of the faceplate 20, or at least to improve such fastening.

(25) The body 12 also has a chinpiece 26 comprising a cover 28 that covers a bottom portion 30 of the faceplate together with a bottom portion 32 of the band 24. As can be seen in FIG. 2, the bottom portion 32 of the band 24 is split and includes a clamping element enabling the band 24 to be clamped against the skirt and the faceplate.

(26) As can be seen in FIGS. 1A and 1B, the band 24 also has slots 34 for receiving one or more elastic straps (not shown).

(27) As can be seen in FIG. 2, the band 24 presents ridges 27 on its inside face 25 for the purpose of preventing the skirt from moving relative to the band.

(28) With reference to FIGS. 1A and 3, it can be seen that the faceplate 20 is shaped to cover the user's face. The faceplate has a transparent plane portion 20a that is to be situated substantially level with the user's eyes, and a rounded portion 20b that is to be situated level with the user's nose and mouth. In this non-limiting example, the rounded portion 20b is transparent. Nevertheless, and without going beyond the ambit of the present disclosure, the rounded portion 20b could be opaque or it could be transparent and covered by an opaque cover.

(29) With reference to FIGS. 1A, 1B, and 2, it can be seen that the flexible skirt 22 has a partition 40 separating a top chamber 50 for vision from a bottom chamber 52 for breathing, the partition 40 being arranged to bear on top of the user's nose so that the user's mouth and nose are situated in the bottom chamber 52, while the user's eyes are situated in the top chamber 50.

(30) The partition 40 is fastened to the faceplate 20 by a fastener fitting that is clipped on fastener lugs 53 (visible in FIG. 3) that project from the inside face of the rounded portion 20b.

(31) The partition includes two orifices 41 that engage with the fastener lugs 53 prior to positioning the fastener fitting.

(32) The partition also has two passages 54 (more clearly visible in FIGS. 2 and 13) that are arranged to allow fresh air to flow between the top chamber 50 and the bottom chamber 52 while the user is breathing in.

(33) Furthermore, in this example, the partition has two check valves 56 that are arranged to allow fresh air to flow from the top chamber 50 towards the bottom chamber 52 only during a stage in which the user is breathing in.

(34) It can thus be understood that the check valves 56 serve to close the above-mentioned passages 54 during a stage while the user is breathing out.

(35) In this example, and as shown in FIG. 13, each of the check valves 56 comprises a membrane 58 constituted by a portion of the flexible skirt. More specifically, in this example, each membrane 58 is constituted by a portion of the partition 40 of the flexible skirt.

(36) The membranes 58 are movable because the partition includes two cutouts 60 that enable each membrane to become detached locally from the remainder of the partition. These cutouts allow the membranes 58 to fold and to separate from the inside face of the faceplate, in particular during a stage of breathing in, so as to open the passages, thereby allowing fresh air to enter into the bottom chamber.

(37) Operation is as follows.

(38) During a stage of breathing out, the exhaled air has the effect of pressing the membranes 58 against the inside face of the rounded portion 20b of the faceplate, thereby having the effect of closing the passages 54 and thus of preventing the exhaled air from passing from the bottom chamber 52 to the top chamber 50.

(39) During a stage of breathing in, the pressure drop that takes place in the bottom chamber 52 has the effect of separating the membranes 58 from the faceplate 20 and of opening the passages 54, thereby allowing fresh air to flow from the snorkel to the bottom chamber 52, passing via the top chamber 50.

(40) With reference to FIG. 7, it can be seen that the snorkel 18 comprises a tubular portion 70 having a first end 72 and a second end 74 remote from the first end 72.

(41) The snorkel 18 also has a cover 76 that is mounted on the second end 74 of the tubular portion 70.

(42) The tubular portion 70 also has holes 78 for allowing air to be exchanged between the atmosphere and the mask.

(43) The snorkel 18 also has a device 80 for closing off the air inlet of the snorkel 18 when it is underwater. The device 80 comprises a float 82 that is movable in translation relative to a plate 84 that has a first orifice 86 and a second orifice 88, the first and second orifices 84 and 86 leading into an inside volume of the cover 76.

(44) The first orifice 86 is in fluid-flow communication with an air duct 90 formed in the tubular portion 70 of the snorkel 18, while the second orifice 88 faces the float 82.

(45) The second orifice 88 is surrounded by a sealing gasket 92 that is shaped to co-operate with the float 82 when the snorkel 18 is underwater.

(46) Operation is as follows.

(47) When the snorkel 18 is out of the water, the float 82 is in a low position, such that air can flow between the air duct 90 and the atmosphere via the holes 78 by passing successively via the first orifice 86, the chamber defined by the inside of the cover 76, and the second orifice 88.

(48) When the snorkel 18 is underwater, the float 82 rises so as to become pressed against the gasket 92, thereby having the effect of closing the second orifice 88 and consequently air can no longer enter into the air duct 90.

(49) Furthermore, in this example, the tubular portion has a single air duct 90 that communicates with the bottom and top chambers.

(50) In accordance with the disclosure, the body 12 also has a device 100 for exhausting exhaled air that puts the bottom chamber 52 into fluid-flow communication with the air duct 90 of the snorkel 18.

(51) It can thus be understood that during a stage of breathing out, the air exhaled into the bottom chamber 52 flows into the exhaled air exhaust device and then into the air duct 90 of the snorkel 18 prior to leaving the snorkel via the holes 78.

(52) With reference to FIG. 3, the exhaled air exhaust device 100 has a first exhaled air exhaust channel 102 that extends along a first side edge 104 of the faceplate.

(53) As can be seen in FIG. 3, the first exhaled air exhaust channel 102 extends between a bottom portion 20c of the faceplate 20 and a top portion 20d of the faceplate.

(54) In this example, the first exhaled air channel 102 is constituted by two adjacent flanges 105, 107 that project from a first side edge 20e of the faceplate.

(55) In this example, the first exhaled exhaust channel 102 is made integrally with the faceplate 20.

(56) The exhaled air exhaust device 100 also includes a second exhaled air exhaust channel 104 that is similar to the first exhaled air exhaust channel 102 and that extends likewise between the bottom portion 20c of the faceplate and the top portion 20d of the faceplate.

(57) Since the second exhaled air exhaust channel is similar to the first exhaled air exhaust channel, only the first exhaled air exhaust channel is described below.

(58) The top portion 20d of the faceplate further includes a top connector 106 that is made integrally with the remainder of the faceplate and that includes a central duct 108, a first side duct 110, and a second side duct 112.

(59) The central duct 108 is in fluid-flow communication with the top chamber 50, while the first side duct 110 is in fluid-flow communication with the first exhaled air exhaust channel 102, and the second side duct 112 is in fluid-flow communication with the second exhaled air exhaust channel 104.

(60) As can be understood from FIG. 3, the first exhaled air exhaust channel 102 and the second exhaled air exhaust channel 104 lead to the bottom chamber 52.

(61) As can be understood from FIGS. 8 and 9, the first end 72 of the tubular portion 70 of the snorkel 18 is shaped to be coupled with the top connector 106 of the faceplate.

(62) Consequently, it can be understood that the central duct 108, and also the first and second side ducts 110 and 112 open out into the single air duct 90 of the snorkel.

(63) With reference to FIG. 4, there follows a description of how the flexible skirt 22 is fastened to the faceplate 20.

(64) As can be understood from FIGS. 1B, 2, and 4, the flexible skirt 22 has a peripheral edge 120 that surrounds a sealing lip 122.

(65) The sealing lip 122 is shaped to bear against the user's face so as to prevent water penetrating into the mask.

(66) The peripheral edge 120 has a first side portion 124 that covers the first exhaled air exhaust channel 102, as can be understood from FIG. 4.

(67) The peripheral edge of the skirt has a first side portion in which there is engaged the first exhaust channel so as to prevent water from penetrating into said first exhaled air exhaust channel.

(68) For this purpose, the first side portion of the peripheral edge of the skirt 20 has a top wall 126 and two side walls 128, 130. It can be understood that the top wall and the two side walls are made integrally with the skirt.

(69) The side walls 128 and 130 encompass the two flanges 105, 107 of the first exhaled air exhaust channel, while the top wall covers the first exhaled air exhaust channel so as to provide sealing.

(70) Preferably, one of the flanges has a longitudinally projecting portion that co-operates with one or the other of the side walls of the peripheral edge of the skirt so as to ensure that the peripheral edge remains properly in place relative to the first exhaled air exhaust channel.

(71) The peripheral edge of the flexible skirt 22 also includes a second side portion 130 that covers the second exhaled air exhaust channel 104.

(72) In accordance with the disclosure, the exhaled air exhaust device 100 has a first check valve 140 that is arranged to allow exhaled air directed from the bottom chamber 52 to flow towards the air duct 90 of the snorkel during a stage in which the user is breathing out.

(73) It can thus be understood that during a stage of breathing out, the flexible flap 58 of the partition 40 closes, while the first check valve 140 of the exhaled air exhaust device opens to allow the exhaled air to flow from the bottom chamber 52 to the exhaled air exhaust device 100, and more particularly towards the first exhaled air exhaust channel 102 and then towards the air duct 90 of the snorkel so as subsequently to be discharged via the holes 78.

(74) Furthermore, the first check valve 140 is closed during a stage in which the user is breathing in. As a result, the user does not breathe in the air previously exhaled that is contained in the snorkel or in the exhaled air exhaust device while breathing in.

(75) As can be seen in FIGS. 5 and 6, the first check valve 140 is arranged in a bottom end portion 101 of the exhaled air exhaust device. More exactly, the first check valve 140 is arranged in a bottom end portion 102a of the first exhaled air exhaust channel.

(76) In this example, the first check valve 140 is arranged between the bottom chamber 50 and the exhaled air exhaust device 100. More precisely, the first check valve 140 is arranged between the bottom chamber 52 and the first exhaled air exhaust channel 102.

(77) Without going beyond the ambit of the present disclosure, the first check valve 140 could be arranged in the bottom chamber 52.

(78) In an advantageous aspect of the disclosure, the first check valve 140 includes a flexible membrane 142 that is constituted by a portion of the flexible skirt 22 in this example.

(79) The flexible membrane is in the form of a substantially rectangular portion that projects from an inside face of the top wall 126.

(80) FIG. 6 shows the first check valve in the closed position in continuous lines. It also shows it in the open position in dashed lines.

(81) The first check valve 140 also has a valve seat 144 arranged to co-operate with the flexible membrane 142, the valve seat 144 being integral with the faceplate. In the closed position, the flexible membrane bears against the valve seat in order to close the openings.

(82) From FIGS. 3, 5, and 6, it can be seen that the first exhaled air exhaust channel 102 in this example includes two openings 150 that open out into the bottom chamber 52.

(83) It can be seen that these two openings are arranged in the inner flange 107 of the exhaled air exhaust device 100.

(84) The flexible membrane 142 is shaped to close both openings 150 during the stage in which the user is breathing in.

(85) It can thus be understood that the flexible membrane 142 is situated inside the first exhaled air exhaust channel 102 in register with the two openings 150.

(86) As explained above, the exhaled air exhaust device 100 also has a second exhaled air exhaust channel 104.

(87) The exhaled air exhaust device 100 also has a second check valve 160 similar to the first check valve 140 and arranged to allow exhaled air coming from the bottom chamber 52 to flow towards the air duct 90 of the snorkel during a stage in which the user is breathing out.

(88) The second check valve 160 is closed during a stage in which the user is breathing in.

(89) In other words, the second check valve 160 operates like the first check valve 140.

(90) Still with reference to FIGS. 5 and 6, it can be seen that the faceplate also includes a purge valve 180 that is arranged in a bottom end portion of the faceplate 20.

(91) This purge valve 180 is covered in part by a protective plate 182, which in this example is formed integrally with the faceplate 20. The function of this protective plate is to prevent the purge valve 180 being damaged.

(92) With reference to FIGS. 7, 8, and 9, it can be seen that the mask includes a system for releasably locking the snorkel to the body. In this example, the locking system comprises a tongue 200 that extends from the first end 72 of the tubular portion 70.

(93) The tongue 200 is also provided with a fastener portion 202.

(94) The band 24 also includes a top 24a having an opening 204 formed therein. This opening 204 is a through opening.

(95) The fastener portion 202 of the tongue 200 is shaped to be received in the opening 204 in order to lock the snorkel to the body.

(96) From FIGS. 8 and 9, it can be understood that the tongue is deformable, so that when engaging the snorkel 18 with the body 12, the top connector 106 engages in the air channel 90 of the snorkel 18 and the fastener portion 202 engages in the top portion of the band 24 and the top connector, until the fastener portion becomes engaged in the opening 204.

(97) It can thus be understood that when the snorkel is mounted on the body, at least a portion of the tongue is arranged below the band. In other words, the tongue engages via the underside of the band. As can be seen in FIG. 9, the tongue is engaged between the top connector 106 and the band.

(98) Furthermore, the fastener portion 202 also constitutes a pushbutton arranged to enable a user to disengage the fastener portion from the opening so as to separate the snorkel from the body.

(99) For this purpose, the user presses on the fastener portion so as to deform the tongue, while also pulling on the snorkel in order to cause the fastener portion to pass under the band. The fastener portion 202 is constituted by a swelling 206 that presents a chamfered shape suitable for becoming engaged in the opening when the snorkel is mounted on the body.

(100) In this example, the swelling is annular in shape.

(101) Furthermore, the tongue 200 presents a reception portion 208 that is arranged between the fastener portion 202 and the tubular portion 70 of the snorkel. The reception portion is shaped to receive a portion 24b of the band 24 that forms an abutment when the snorkel is mounted on the body.

(102) Furthermore, the reception portion 208 and the abutment-forming portion of the band 24 are engaged with each other by co-operating shapes when the snorkel is mounted on the body, thereby having the effect of preventing untimely unlocking of the snorkel.

(103) Furthermore, the reception portion 208 has two ridges 210, 212 arranged on either side of said reception portion 208, these ridges extending between the first end of the tubular portion and the fastener portion, and co-operating with two grooves 214, 216 (visible in FIG. 10) in the band when the snorkel is mounted on the body. The advantage is to ensure that the snorkel is stable when it is mounted on the body.

(104) Furthermore, the top connector 106 has a setback 220 that is situated under the fastener portion when the snorkel is mounted on the body. This setback receives the deformed tongue while the snorkel is being engaged on the body. It also serves to leave space for deforming the tongue while disengaging the snorkel from the body.

(105) Finally, it can be seen that the mask also has a sealing gasket 250 arranged between the body and the snorkel. This sealing gasket 250 is received in an annular groove 252 arranged in the top connector of the faceplate.

(106) With reference to FIGS. 11 and 12, there follows a description of a support for fastening an accessory, e.g. a camera. This fastener support is preferably removable.

(107) The fastener support 300 has a mounting portion proper 302 that presents a cylindrical fastener member 304 for receiving a camera (in known manner). The fastener support 300 is releasably mounted on the body of the mask.

(108) The fastener support 300 also has two arms 306 and 308 that are terminated in two tabs 310 that are shaped to co-operate with the band of the body so as to hold the fastener support relative to the body.

(109) The fastener support 300 also has a connection portion 312 that extends between the arms 306, 308 and the fastener member 304. This connection portion is hook-shaped so as to bear against the faceplate when the support is mounted on the mask, so that the tabs and the connection portion prevent the fastener support from moving relative to the body. In addition, the hook shape is arranged in such a manner that the fastener member 304 is substantially level with the user's eyes. Because of this advantageous position, the camera is necessarily underwater when the body of the mask is underwater with the snorkel out of the water. One advantage is thus to ensure that the camera is filming under water and not the surface of the water.

(110) The diving mask also has a holder device 400 (visible in FIGS. 1B, 2, and 7) that has a central attachment element 402 situated between two side attachment elements 404 and 406.

(111) The central attachment element 402 is in the form of a mushroom having its head 403 shaped to be inserted in succession through a first hole 408 and then a second hole 410 beside the first hole, the holes being formed in the proximity of the first end of the tubular portion of the snorkel. As can be seen in FIG. 7, the first hole 408 presents a diameter greater than the diameter of the second hole 410. The head 403 of the central attachment element 402 presents a diameter that is smaller than the diameter of the first hole but greater than the diameter of the second hole. It can thus be understood that the central attachment element 402 is secured to the snorkel when its head is taken into the second hole 410.

(112) As can be understood from FIGS. 1B and 2, the side attachment elements 404 and 406 are in the form of pins that are to be inserted in openings 412 and 414 arranged in the frame, preferably in the band, so as to secure the holder device relative to the body.

(113) It can thus be understood that the holder device 400 serves to hold the snorkel to the body, even when the tubular portion of the snorkel is decoupled for fluid flow purposes from the top connector, so as to avoid losing the snorkel.

(114) The retention device 400 is preferably made out of a flexible material of rubber type.
