[0001] BACKGROUND OF THE INVENTION The present invention relates to the field of diving masks, and in particular the masks used for underwater hiking, also called PMT (Palmes-Masque-Tuba), in English "snorkeling". This underwater activity allows you to observe the seabed while swimming on the surface of the water. The underwater hiker must be able to hold the head underwater while breathing.
[0002] Generally, the underwater hiker is equipped with a mask for vision, and a snorkel for breathing. The tuba consists of a tube whose lower end is provided with a mouth portion which is housed in the mouth of the user, and an upper end for both the admission of fresh air and Exhaled air exhaust.
[0003] It is known that such a material has many disadvantages. First of all, breathing by mouth is not natural, some people have difficulty breathing orally with a snorkel. Another disadvantage is that it is not possible to speak underwater when you have a snorkel in your mouth.
[0004] Another disadvantage, related to the use of the mask, is that the inner wall of the visor generally tends to fog, which affects the good visibility, and which forces the user to regularly clean his mask. The appearance of mist is due to the fact that the user's nose opens into the vision chamber located between the visor and the eyes of the user. Also, the use of this mask-snorkel device is uncomfortable. To remedy this drawback, document FR 2 720 050 proposes a diving mask for breathing through the nose and mouth.
[0005] To do this, the diving mask includes: a frame surrounding the face of the user; a visor surrounded by the frame; a flexible skirt attached to the frame, the skirt having a partition defining an upper chamber for viewing a lower chamber for breathing, the partition being arranged to bear above the nose of the user so that the mouth and the nose of the user are in the lower chamber, while the user's eyes are in the upper chamber, the partition having at least one passage arranged to allow inspired airflow directed from the upper chamber to the lower chamber during an inspiration phase of the user; a snorkel having an inspired air intake channel and at least a first exhaled air exhaust channel, said snorkel being in the extension of the upper part of the frame, the inspired air intake channel opening into the upper chamber, while the first exhaled air outlet channel communicates with the lower chamber. According to this document, the exhaled air circulates in the flexible hollow seal of the skirt which adheres between the mask and the face. Such a mask, however, has a disadvantage. If the user is using the mask attachment system too hard, the flexible hollow seal will collapse against the face, which will cause clogging of the line through which the expired airflow flows. On the other hand, if the user does not sufficiently serve the fixing system, there will not be a perfect seal between the face and the skirt, as a result of which water may penetrate inside the chambers. lower or upper, which is not desirable. OBJECT AND SUMMARY OF THE INVENTION An object of the invention is to propose a diving mask that overcomes the aforementioned drawbacks. The invention achieves its object by the fact that: the frame is rigid and comprises at least a first duct for exhaled air, said first duct having an upper end opening into the exhaled air exhaust duct, and an lower end fluidly communicating with the lower chamber. Since the frame is rigid, it is understood that the first duct can not be crushed on itself, unlike the hollow seal of the prior art. The frame therefore has at least a dual function, namely to maintain the visor and constitute a means of air circulation. The first conduit is preferably an internal conduit formed in the frame.
[0006] By visor, we mean the faceshield through which the user can see the objects outside the mask. Frame means the peripheral portion of the dive mask that surrounds the aforementioned facial screen, the flexible skirt being preferentially attached to the frame.
[0007] According to the invention, the frame can form a separate part or a single piece with the visor, in which case the frame is constituted by the peripheral portion of the visor. In the latter case, the flexible skirt is preferably fixed to the frame constituted by the peripheral portion of the visor. The frame may also be in several parts, for example a first part forming a single piece with the visor and a second part arranged around the first part. In the latter case, the flexible skirt can be attached to the first part of the frame. The connection between the frame and the flexible skirt is preferably obtained by a flexible junction between the flexible skirt and the lower end of the first conduit. Preferably, the frame comprises an upper portion and a lower portion assembled with the upper portion, and the first conduit is formed in the upper portion. More preferably, the first conduit opens at the lower end of the upper portion.
[0008] Advantageously, the flexible skirt further comprises at least a first sleeve projecting from a first lateral edge of the flexible skirt extending towards the upper part of the mask, the first sleeve being fluidly connected with the first conduit and having a lower end. opening into the lower chamber. The first sleeve protruding from the first side edge of the flexible skirt, it is not likely to be crushed on itself in case of significant tightening of the fastening system. Advantageously, the first sleeve has an upper end, opposite the lower end, fluidly connected with the lower end of the first conduit. Advantageously, the first sleeve forms a single piece with the flexible skirt, and extends outside the flexible skirt up towards the upper part of the mask. Preferably, the flexible skirt is made of silicone, while the frame is made of rigid plastic, such as polypropylene or polycarbonate.
[0009] Advantageously, the frame comprises at least a first lateral connection engaged in the upper end of the first sleeve. Preferably, this first lateral connection extends towards the lower part of the mask. This first lateral connection is preferably curved towards the inside of the mask. More preferably, the upper end of the first sleeve has a lower cross section smaller than the cross section of the first side connector. An interest is to improve the seal between the upper end of the first sleeve and the first lateral connection. Preferably, the upper end of the first sleeve is flush with a lateral side of the frame, which makes it possible to obtain a frame having a lateral side devoid of roughness. With this arrangement, the sleeve does not offer a plug, and therefore does not risk being inadvertently disconnected from the first side connection. According to a preferred embodiment, the first lateral connection comprises at least one rib on its outer face, said rib cooperating with the inner face of the upper end of the first sleeve. The upper end of the first sleeve deforms in contact with the rib. This improves the seal between the first sleeve and the first lateral connection, while improving the anchoring of the first sleeve to the first lateral connection. Advantageously, the frame comprises an upper portion and a lower portion, the first conduit is formed in the upper portion of the frame, the first conduit extends between the top of the frame and a lower end of the upper portion of the frame, and the first lateral connection protrudes from the lower end of the upper portion. According to a preferred embodiment, the lower portion of the frame has an upper end assembled with the lower end of the upper portion. In this embodiment, the frame consists of at least two parts, namely the upper portion constituting an upper hoop surrounding the upper periphery of the flexible skirt, and the lower portion, formed of one or more elements constituting a lower strapping surrounding the lower periphery of the flexible skirt.
[0010] Such an arrangement is advantageous since it allows the mask to be manufactured in a minimum of parts. The upper portion, constituting an upper strapping, is preferably molded in one piece.
[0011] According to a variant, the lower portion and the upper portion of the frame form a single piece. According to a preferred method of assembly, the flexible skirt is attached to the upper and lower portions of the frame. Advantageously, the skirt comprises a peripheral sealing lip arranged to bear against the face of the user, and the first sleeve flanks said peripheral sealing lip. Thus, and as mentioned above, the first sleeve extends outside the flexible skirt up to the upper part of the mask. This avoids crushing the first sleeve on itself, and thus an obstruction of the sleeve, while promoting a flow of the exhaled air flow to the upper portion of the frame, which promotes the evacuation of air flawed. Advantageously, the partition forms a single piece with the flexible skirt. The flexible skirt is therefore a single piece, it being understood that the first sleeve forms a single piece with the flexible skirt. Advantageously, the flexible skirt comprises an upper sleeve cooperating with a top fitting of the frame into which opens the intake air channel inspired tuba, said top sleeve 25 opening into the upper chamber. Preferably, the top sleeve forms a single piece with the flexible skirt. More preferably, the top sleeve is disposed between the peripheral lip and the upper portion of the frame. Preferably, the uppermost connector projects from an upper portion of the frame, while the uppermost sleeve protrudes from an upper edge of the flexible skirt, the uppermost fitting and the uppermost sleeve engaging one into the other. Preferably, the top fitting engages inside the top sleeve. The cross section of the top sleeve is slightly smaller than the cross section of the top fitting to provide a seal between the two members. More preferably, the top sleeve has at least one rib projecting from its outer face, said rib cooperating with an inner wall of the top connector, and to further improve the seal between the two elements connected to each other. 'other.
[0012] According to a preferred embodiment of the invention, the tuba further comprises a second expired air outlet channel, the frame further comprises a second duct for exhaled air, which has an upper end opening into the second channel exhaled air, and a lower end fluidly communicating with the lower chamber. Thus, the mask according to the invention comprises two independent circuits for exhaled air. Such an arrangement has several advantages. In the first place, it facilitates breathing, in particular by making it possible to expel the stale air more quickly, which is particularly necessary when the user makes a muscular effort, for example by swimming more quickly. Second, the underwater hiker can continue to breathe even if one of the two circuits of exhaled air, for example the first conduit, would become clogged. Advantageously, the flexible skirt comprises a second sleeve projecting from a second lateral edge of the skirt, opposite to the first lateral edge, said second sleeve having a lower end opening into the lower chamber and an upper end, opposite to the lower end, fluidly connected with the lower end of the second conduit.
[0013] Advantageously, the tuba has an upper portion provided with a cage permeable to air, the tuba further comprising a float movable in said cage, said float having an upper end provided with a closure device, said float being arranged such that when the snorkel is immersed in the water, the float moves so that the closure device closes the inlet of the snorkel Preferably, the float is a hollow element containing a volume of air, while that the shutter device consists of a flexible membrane. Still preferably, the float comprises a body in which is fitted the flexible membrane, which gives the float very good strength.
[0014] The air permeable cage is preferably constituted by an upper portion of the tuba in which slots are formed. Preferably, the cage has in its lower part holes for the evacuation of water that could enter the latter.
[0015] The cage is also disposed on a side of the upper body of the tuba in which the inlet and exhaust channels extend. Advantageously, the tuba further comprises a plate comprising: a main orifice communicating with the inlet of the tuba; an inlet port communicating with the inlet of the inspired air intake channel; at least a first output port communicating with the output of the first exhaust channel; a first non-return valve arranged to close the inlet orifice during an expiration phase; a second non-return valve arranged to close the first outlet orifice during an inspiration phase; the tuba further comprising a fluidic communication chamber into which open the main port, the inlet and the first outlet. It is understood that the shutter device is configured to close the main orifice in the case where the snorkel is immersed in water. To do this, the submerged float, undergoing an Archimedes pressure, moves until the closure device, preferably a flexible membrane, closes the main orifice. In this case, the entrance of the tuba is closed. The user is therefore unlikely to suck water. It may, however, expire as the expired airflow can counteract the buoyancy force acting on the float.
[0016] When the snorkel is out of the water, and during an inspiration phase, the fresh air enters the fluidic communication chamber through the main orifice when the float, in the down position because of the use of gravity, does not obstruct the entrance of the tuba. The second non-return valve is closed while the first valve passes fresh air from the fluidic communication chamber through the inlet orifice, the fresh air then flowing successively into the intake duct. Inspired air, in the upper chamber via the top fitting and the summit sleeve, then into the lower chamber where it is inspired by the user. It is specified that the non-return valve of the partition allows the inspired air to pass through the partition.
[0017] When the snorkel is out of the water, and during an expiration phase, the air exhaled by the user in the lower chamber flows successively into the first sleeve, (as well as into the second sleeve when it is present), then in the first duct, (and in the second duct when it is present), then in the first exhaled air exhaust duct, (and in the second exhaled air exhaust duct when present). The exhaled air then flows into the fluidic communication chamber via the first exit port and exits the fluidic communication chamber via the main port. The stale air then escapes out of the tuba.
[0018] Preferably, the tuba has a body having an upper end, the inspired air intake channel and the first exhaled air exhaust channel extend into the body, and the fluidic communication chamber is formed in a hood tightly attached to the upper end of the body.
[0019] According to an advantageous aspect of the invention, the tuba is removable or tilting. This reduces the size of the mask when it is not used. Advantageously, the mask according to the invention further comprises an elastic holding strap which extends between an upper portion of the frame and a lower portion of the frame. Preferably, the elastic strap comprises at least one point of connection with one or the other of the lower or upper portions of the frame, said connection point being constituted by the cooperation of a beaded end of the elastic strap with a slot formed in the lower or upper portion of the frame. An interest is to facilitate the mounting operation of the elastic strap, its retention relative to the frame. Preferably, the slot is formed by a loop fixed to the frame. Still preferably, the elastic strap has two upper connection points with the upper portion of the frame, and two lower connection points with the lower portion of the frame.
[0020] Thus, the elastic strap has the shape of an "X" that covers the rear portion of the user's head, which has the effect of providing a stable maintenance of the mask on the user's head. In addition, the upper portion of the frame advantageously has a triple function, namely to maintain the visor, form an exhaled and inspired air flow means, and allow the attachment of the elastic strap. Advantageously, the diving mask according to the invention further comprises a purge valve disposed in the breathing chamber for discharging liquid out of the mask. By a strong expiration, the water possibly contained in the lower chamber will be expelled out of the mask via the purge valve. Preferably, to make the wearing of the mask more comfortable, the partition has a fold forming a lip intended to come into contact with the user's nose. Advantageously, the passage of the partition comprises a non-return valve arranged to allow an inspired air flow directed solely from the upper chamber to the lower chamber during a phase of inspiration of the user.
[0021] Thanks to the presence of the non-return valve, the exhaled air flow does not rise in the upper chamber, which improves the efficiency of the anti-mist system of the mask. Advantageously, the snorkel comprises an elongated body whose lower end comes to grip with an extension of the frame which projects from the upper end of the frame, the extension comprising a central channel arranged to communicate with the intake channel of inspired air when the snorkel is attached to the frame, and at least one exhalation channel arranged to communicate with the first exhaled air exhaust channel.

DETAILED DESCRIPTION OF THE INVENTION FIG. 1 shows an exemplary embodiment of a diving mask 10 according to the present invention. The diving mask 10 comprises a frame 12 of generally oblong shape having an upper portion 12a and a lower portion 12b. In this example, the frame 12 has an upper portion 14 forming an upper strapping and a lower portion 16 forming a lower strapping.
[0023] The upper 14 and lower 16 portions of the frame are attached to each other so that the frame forms a strapping surrounding the face of the user. The diving mask 10 further includes a visor 18 which is integral with the frame 12. In this example, the visor 18 is made of a transparent hard plastic material. As can be understood from FIG. 1, the frame 12 surrounds the visor 18. In this nonlimiting example, the frame is a separate part of the visor. Without departing from the scope of the invention, the frame could however form a single piece with the visor. This mask further comprises a purge valve 17 for the evacuation of water that could have entered the mask. The dive mask 10 further includes a snorkel 20 which has a lower portion 20a connected to the upper portion 12a of the frame. In this example, the tuba 20 is removable. It can be unclipped from the frame 12, which reduces the size of the mask when the latter is not used. The tuba 20, better visible in Figure 2, also has an upper portion 20b which is provided with a cage 22 permeable to air.
[0024] As will be described in more detail below, the tuba 20 further comprises a cover 24 which cooperates with the cage 22. Referring now to the exploded view, it can be seen that the lower portion 16 of the frame 12 comprises a first element 16 'and a second element 16 "which are fixed to each other in order to form the lower portion, It is also noted that the tuba 20 comprises an elongated body 26 whose lower end 26a comes to bear with a extension 28 of the upper portion 14 of the frame 12 which protrudes from the upper portion 12a of the frame.
[0025] Furthermore, the tuba 20 comprises a float 30 which is movable in the cage 22, the float having an upper end 30a provided with a closure device 32. As will be explained in more detail below, the float 30 is arranged so that when the tuba 20 is immersed in the water, the float moves so that the closure device 32, in this case a flexible membrane, comes close the inlet of the tuba.
[0026] Referring to FIGS. 3, 4 and 5, it can be seen that the flexible skirt 40 has a generally oblong shape substantially of the same dimension as the frame 12 and the visor 18. The flexible skirt 40 is disposed between the visor 18 and the frame 14 .
[0027] More specifically, the flexible skirt has a periphery 42 which has an upper portion which is fixed with the lower portion of the frame. The flexible skirt 40 further comprises a peripheral sealing lip 44 which is arranged to bear against the face of the user, so as to prevent water from entering between the face of the user and the visor. The flexible skirt 40 further comprises a partition 46 which is arranged to bear above the nose of the user. This partition 46 thus delimits an upper chamber 50 for viewing, a lower chamber 52 for breathing. As can be seen from FIG. 5, which illustrates the frame 12 assembled with the visor 18 and the skirt 40, the mouth and the nose of the user are in the lower chamber 52, while the eyes of the the user are in the upper chamber 50.
[0028] In other words, the upper chamber 50 is delimited by the visor, the eyes of the user, the upper wall 46a of the partition 46, and the portion of the flexible skirt that extends above the partition 46. the lower chamber 52 is delimited by the visor 18, the mouth and the nose of the user, the lower part 46b of the partition 46, and the part of the flexible skirt which extends below the partition 46. In this example, the partition comprises a pair of passages provided with non-return valves 54 which are arranged to allow an inspired air flow directed solely from the upper chamber 50 to the lower chamber 52 during an inspiration phase of the user. In this example, the flexible skirt is made of silicone, and forms a single piece with the partition 46, the sealing lip 44 and the periphery 42. In FIG. 6, the tuba 20 has been illustrated, seen from its lower part 20a.
[0029] It is found that the tuba 20 comprises an inspired air intake channel 60 which extends between the lower part of the tuba 20a and the upper part 20b of the tuba. This inspired air intake channel thus extends in the longitudinal direction of the body 26. As will be explained in more detail below, the inspired air intake channel opens into the upper chamber. The tuba 20 further comprises a first exhaled air exhaust channel 62, which also extends in the longitudinal direction of the body 26 between the lower part 20a and the upper part 20b of the tuba 20. This first exhaust channel Expired air 62 communicates with lower chamber 52. In this example, tuba 20 has a second exhaled air exhaust channel 64 similar to the first expired air exhaust channel 62.
[0030] As can be seen in FIG. 6, the inspired air admission channel 60 is separated from the first and second air exhaust ducts 62, 64 by two longitudinal walls 66, 68. As can be seen in FIG. 7, which shows the frame 12 assembled to the flexible skirt 40 in plan view, the extension 28 also includes a central channel 70 arranged to communicate with the inspired air intake channel 60 when the snorkel is attached to the frame , and two exhalation channels 72, 74 arranged to communicate respectively with the first and second expired air exhaust channels 62, 64. Referring now to FIG. 8, it can be seen that the frame 12 further comprises a top connector 80 which protrudes from the upper portion 14 of the frame 12. The flexible skirt 40 has for its part an upper sleeve 82 which protrudes from an upper portion of the flexible skirt 40 opening into the upper chamber 50. It can be seen that that the connection d summit 80 engages inside the top sleeve 82 to create a tight connection between these two elements. In Figure 8, the arrow F1 symbolizes the flow of fresh air inspired. It is understood that during an inspiration phase, fresh air enters the tuba, flows into the inspired air intake channel 60, and into the upper chamber 50 through the top sleeve 82. We will now be interested in the expired air circuit.
[0031] According to the invention, in the frame 12, and more particularly in the upper portion 14 of said frame, is provided a first duct 90 for exhaled air, and a second duct 92 for exhaled air. The first duct 90 forms a first internal duct formed in the frame, while the second duct 92 forms a second internal duct formed in the frame. As can be seen in FIG. 9, these first and second ducts are disposed on either side of a longitudinal plane P of the mask. This plane P is here the plane of symmetry of the mask.
[0032] Insofar as the first and second conduits 90, 92 are identical, only the first conduit 90 will be described. The latter has an upper end 90a which corresponds to the output of the channel 72 illustrated in FIG. in addition to a lower end 90b.
[0033] Furthermore, according to the invention, the flexible skirt 40 further comprises a first sleeve 100 projecting from a first lateral edge 41 of the flexible skirt 40 extending towards the upper part 12a of the frame 12. The first sleeve, which forms a single piece with the flexible skirt, has a lower end 100a opening into the lower chamber 52 and an upper end 100b opposite the lower end, which is fluidly connected with the lower end of the first conduit. It is understood that the sleeve forms a pipe for exhaled air. The flexible skirt further comprises a second sleeve 200, identical to the first sleeve 100, the second sleeve 200 protruding from a second side edge 43 of the skirt 40, opposite the first side edge. The second sleeve has a lower end 200a opening into the lower chamber 52 and an upper end 200b opposite the lower end which is fluidly connected with the lower end 92b of the second conduit 92. Referring to FIG. that the first conduit 90 extends between the top of the frame and a lower end 14a of the upper portion 14 of the frame.
[0034] Referring to FIGS. 9, 10A and 10B, it can be seen that the frame 12, and more precisely the lower end of the upper portion 14 of the frame 12, comprises a first lateral connection 110 which is engaged in the upper end 100b of the first sleeve. To improve the strength and tightness, the first lateral connection 110 has ribs 112 on its outer face 110a, the ribs 112 cooperate with the inner face 101 of the upper end of the first sleeve. Referring again to FIG. 9, it can be seen that the upper end of the first sleeve is flush with a lateral side 12c of the frame 12. It is thus clear that the exhaled air flows successively through the first sleeve 100, through the first conduit 90 then through the first expired air exhaust channel 62. This outgoing air flow is illustrated by the arrow F2. The arrow F3 illustrates the other outgoing air circuit flowing via the second sleeve 200 and the second conduit 92. With the aid of FIGS. 11 to 13, the upper portion will now be described more particularly. 20. The snorkel 20 of the mask according to the invention comprises at its upper end means for regulating the inflow and outflow of air into the tuba. For this purpose, the tuba 20 comprises a plate 300 which is arranged in a sealed manner between the cap 24 and the upper end 26b of the body 26 of the tuba 20. This plate comprises a main orifice 302 communicating with the inlet E of the tuba . In this example, the inlet E of the tuba is made through slots 23 formed in the cage 22. The plate 300 further comprises an inlet port 304 communicating with the inlet 60a of the air emission channel The wafer 300 further includes a first outlet port 306 which communicates with the outlet 62a of the first expired air exhaust channel 62. The wafer 300 further includes a second outlet port 308 which communicates with the outlet port 308. outlet 64a of the second exhaled air outlet channel. As can be seen from FIG. 11, the sections of the main orifice 302, the inlet orifice 304 and the two outlet orifices 306, 308 substantially correspond to the transverse sections 35 of the duct. inspired air intake 60 and exhaled air exhaust channels 62, 64.
[0035] The wafer 300 further comprises a first non-return valve 310 arranged opposite the first inlet port 304, in order to close off said inlet orifice during an expiration phase. The wafer 300 further comprises a second non-return valve 312, arranged opposite the first outlet orifice in order to close said first outlet orifice during an inspiration phase. And, in this example, the plate 300 also comprises a third check valve 312 which is arranged to close the second outlet orifice during an inspiration phase. The tuba 20 further comprises a fluidic communication chamber 350 into which the main orifice 302, the inlet orifice 304, the first outlet orifice 306 and the second outlet orifice 308 open. The fluidic communication chamber 350 is formed in the cover 24 which is sealingly attached to the upper end of the body 26.
[0036] In FIG. 12, the configuration of the tuba is illustrated during an inspiration phase. It is understood that the fresh air inspired illustrated by the arrow F1, enters the cage 22 via the slots 23, then enters the fluid communication chamber 350 via the main port 302 and enters the air intake channel inspired 60 through the inlet port 304, the first non-return valve 310 then being open to allow the flow of air to pass. In Figure 13, there is illustrated the case in which the tuba is immersed in water. The float 30, under the action of buoyancy, rises in the cage 22 until the closure device 32 closes the main orifice 302, which has the effect of closing the inlet of the tuba. As illustrated in FIG. 14, according to another advantageous aspect of the invention, the diving mask 10 further comprises an elastic holding strap 400 which extends between the upper portion 14 of the frame and the lower portion 16. The elastic strap 400 has two connection points 402, 404 with the upper portion 14 and two connection points 406, 408 with the lower portion 16. It is then found that the elastic strap forms an "X". The upper portion 14 of the frame 12 further includes two loops 410, 412 in which are engaged the ends of the two upper portions of the strap portions 414, 416. It is noted that the ends of these two strap portions 414, 416 form bead 418, 420 wider than the slots 422, 424 formed in the loops, which has the effect of ensuring the maintenance of the elastic strap 400 to the frame. 10
