Definitions
- the present disclosure relates to a swim mask.
- a swim mask or diving mask may be used for underwater hiking, also referred to as snorkeling.
- This underwater hiking activity allows the snorkeler to observe underwater attractions, such as the seabed, while swimming on the surface of the water. The underwater hiker must therefore be able to keep his head underwater while breathing.
- the snorkeler may equip himself 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 buccal portion which fits into the snorkeler's mouth, and an upper end allowing both the admission of fresh air and the exhaust of exhaled air.
- One of the drawbacks of using such a snorkel is that breathing through the mouth may be perceived as unnatural as a result of which some people find it difficult to breathe orally using a snorkel.
- Another disadvantage is that it is not possible to speak underwater when you have a snorkel in your mouth.
- EP3140186 discloses a swim mask that may overcome the drawbacks mentioned previously.
- the swim mask from EP3140186 may, however, be improved to provide a swim mask that is relative comfortable to the user while realising a relative good view of the underwater attractions.
- the objective of the present disclosure is to provide a swim mask that is relatively comfortable to wear while realising a relative good viewing experience to a user of the swim mask.
- the objective is achieved by the swim mask according to the present disclosure by, the swim mask comprising: a visor; a frame having an upper part and surrounding said visor; a flexible skirt mounted to said frame and arranged for realising, during use, a watertight seal between said swim mask and the face of said user; a partition delimiting an upper chamber for vision and a lower chamber for respiration, said partition being arranged to contact, during use, said face of said user such that the mouth and the nostrils of said user are positioned within said lower chamber for respiration and wherein the eyes of said user are positioned within said upper chamber for allowing said user to view through said visor, said partition comprising at least one passage arranged to allow air to enter said lower chamber from said upper chamber during an inhalation phase; an inlet conduit extending beyond said upper part of said frame, upwards in use, and comprising an inlet opening, at
- the present disclosure relies at least partly on the insight that providing a relative compact swim mask is beneficial for the comfort of the user.
- the thickness of side frame parts between the upper part of the frame and a lower part of the frame may be relatively small.
- the lower frame part is to be understood as being the frame part that, during use, is near the chin of the user.
- the side frame parts are positioned at opposite sides of the face of the user near the ears of the user. Since the outlet conduit of the swim mask according to the present disclosure is provided in a centre part of the swim mask, there is no longer a need for relative thick side frame parts between the upper part and the lower part of the frame for housing the outlet conduit therein.
- a relative low thickness of the side frame parts is beneficial for realising a swim mask having a relative low weight which is beneficial for realising a relative comfortable wearing experience to the user.
- a further benefit of the relative low thickness of the side frame parts is that the view of the user, i.e. the field of view of the user, via the visor, near the sides of his face is no longer blocked, or at least blocked to a lesser extent, by the frame due to the relative small thickness of the frame at these locations.
- This is beneficial for realizing a relative good viewing experience to a user of the swim mask since the field of view to the user may be relatively large.
- the present disclosure yet further at least partly relies on the insight that an object that is provided in an area between the eyes and relatively close to the face does not, or only to a relative limited extent, block the field of view of the user.
- the outlet conduit By providing the outlet conduit, during use, in an area between the eyes in front of the face, the field of view of the user is not blocked, or only to a relative little extent, by the outlet conduit.
- a lower part of said outlet conduit is in fluid communication with said lower chamber for exhausting said air, during said exhaling phase, from said lower chamber via said outlet conduit.
- said outlet conduit is provided with a one-way valve arranged for allowing air to be exhausted from said outlet conduit and blocking fluid to enter, via said one-way valve, said outlet conduit. This is beneficial for avoiding liquid to enter the outlet conduit during swimming.
- said exhaust opening is provided with a one-way valve arranged for allowing air to be exhausted from said outlet conduit and blocking fluid to enter, via said one-way valve, said outlet conduit. This is beneficial for avoiding liquid to enter the outlet conduit during swimming.
- said exhaust opening is provided in an upper half of said upper part, preferably in an upper quarter of said upper part. This is beneficial for realising a relative comfortable exhaling for the user during the exhaling phase.
- said upper part of said frame comprises a plurality of said exhaust openings in fluid connection with said outlet conduit. A plurality of exhaust openings may be beneficial for reducing the flow resistance of exhaled air present in the outlet conduit. This is beneficial for realising a relative comfortable exhaling for the user during the exhaling phase.
- said plurality of said exhaust openings are provided in an upper half of said upper part, preferably in an upper quarter of said upper part. This is beneficial for realising a relative comfortable exhaling for the user during the exhaling phase.
- the exhaust opening is provided in the frame and, in use, below the inlet conduit. This is beneficial for realising a relative short outlet conduit thereby realising a relative comfortable exhaling for the user during the exhaling phase while avoiding that exhaled air is hampering the viewing experience of the user through the visor.
- said outlet conduit is provided at least partly within said upper chamber and passes through a centre of said upper chamber, preferably in a centre part of the visor. This allows for providing the outlet conduit, during use, at a relative small distance from the face of the user at a location that does not, or only to a limited extent, hamper the viewing experience of the user. It is noted that by placing the outlet conduit relatively close to the face and in between the eyes, the user may view around the outlet conduit.
- the centre part of the upper chamber is such that the centre part of the upper chamber, during use, substantially corresponds to the shape of the nose of the user for allowing the user to view around the outlet conduit.
- said outlet conduit is provided within said upper chamber and passes through a centre of said upper chamber.
- said outlet conduit extends at least partly between said upper part of said frame and said partition, preferably between said upper part of said frame and an upper part of said partition. This allows for realising a relative short outlet conduit having a relative low flow resistance for the exhaled air. This is beneficial for realising a relative comfortable exhaling for the user during the exhaling phase.
- said complete outlet conduit extends between said upper part of said frame and said partition, preferably between said upper part of said frame and an upper part of said partition.
- said partition is arranged for bearing upon at least a lower half, preferably upon at least a lower three-quarter, of the nose of the user. This is beneficial for providing a swim mask provided with a relative short outlet conduit thereby realising a relative comfortable exhaling for the user during the exhaling phase.
- said visor comprises two visor elements, wherein said two visor elements are connected to each other via said inlet conduit. This is beneficial for realising a relative cost effective swim mask while realising a relative good viewing experience to the user.
- said two visor elements are flat. This is beneficial for realising a relative good viewing experience to the user.
- a section of said visor that, in use, is in front of said eyes of said user is flat. This is beneficial for avoiding, or at least significantly reducing, optical distortion, by the visor thereby providing a relative good viewing experience to the user.
- said two visor elements are identical. This is beneficial for realising a relative cost effective swim mask while realising a relative good viewing experience to the user.
- said flexible skirt comprises said partition.
- said frame and/or said visor is/are rigid.
- said inlet conduit comprises inlet conduit elements that are mutually telescopically arranged for allowing said user to set a length of said inlet conduit within a predetermined range.
- said passage is provided with a further one-way valve arranged for allowing air to exhaust from said upper chamber into said lower chamber and blocking air to enter said upper chamber, via said one-way valve, from said lower chamber. This is beneficial for avoiding, or at least significantly reducing the risk, of fogging of the visor thereby realising a relative good viewing experience to a user of the swim mask.
- said outlet conduit and/or said frame is/are transparent for visible light for allowing said user to view through said outlet conduit and/or said frame. This is beneficial for realising a relative good viewing experience to a user of the swim mask.
- said visor comprises an inner wall delimiting the upper chamber and an outer wall, during use, directed away from said user, wherein said outlet conduit is provided between said inner wall and said outer wall.
- said swim mask comprises a purge valve positioned in said lower chamber and arranged to evacuate liquid to outside said swim mask. This is beneficial for allowing a user to purge liquid from the lower chamber in a relative practical manner while wearing the swim mask.
- said outlet conduit is shorter than said inlet conduit, preferably, wherein said inlet conduit is in the range of 1.5 to 2 times longer than said outlet conduit.
- a relative short outlet conduit is beneficial for realising a relative comfortable exhaling for the user during the exhaling phase.

- the flexible skirt 9 comprises a resilient material and is arranged for realising a watertight seal between the swim mask 1 and the face of the user when being pressed against the face of the user.
- the flexible skirt 9 comprises a partition 11 that separates an upper chamber 13 of the swim mask 1 from a lower chamber 15 of the swim mask 1.
- the partition 11 is arranged such that, when the skirt 9 is pressed against the face for realising the watertight seal, is in contact with the face of the user such that the mouth and the nostrils of the user are positioned within the lower chamber 15 for respiration and wherein the eyes of the user are positioned within the upper chamber 13 for allowing the user to view through the visor 3.
- the partition 11 comprises two passages 17 that are each provided with a one-way valve 31.
- the one-way valves 31 are arranged for allowing air to exhaust from the upper chamber 13 into the lower chamber 15 and blocking air to enter the upper chamber 13, via the one-way valves 31 , from said lower chamber 15.
- the partition 11 is further provided with an outlet opening 35 that is in fluid connection with an outlet conduit 23.
- the outlet conduit 23 is arranged for exhausting air, via exhaust openings 25, from the lower chamber 15 during an exhaling phase of the user.
- the exhaust opening 25 are provided in an upper part 7 of the frame 5 and are in fluid communication with the outlet conduit 23 via a recess 37.
- the outlet conduit 23 is at least partly received in the recess 37.
- the outlet conduit 23 is provided inside the upper chamber 13 at a relative small distance, in use, from the face of the user such that the outlet conduit 23 extends in a flat virtual plane between the eyes of the user between the partition 11 and the upper part 7 of the frame 5.
- the exhaust openings 25 are provided with one-way valves 27.
- the one-way valves 27 are arranged for allowing air to be exhausted from the lower chamber 15, via the outlet conduit 23, and blocking fluid to enter, via the one-way valves 27, the lower chamber 15 via the outlet conduit 23.
- the swim mask 19 further comprises an inlet conduit 19.
- the inlet conduit 19 is provided at an upper side of the swim mask 1 such that during use, an inlet opening 21 of the inlet conduit 19 is provided outside the water for allowing the user to inhale air, during an inhaling phase, via the inlet conduit 19.
- the inlet conduit 19 is in fluid communication with the upper chamber 13 for allowing entry of ambient air in the upper chamber 13.
- the inlet conduit 19 comprises inlet conduit elements 29 that are mutually connected via sealing gaskets 45 and coupling organs 47 such that the inlet conduit elements 29 may be displaced relative to each other in a direction A for allowing the user to adapt a length of the inlet conduit 19.
- the sealing gaskets 45 are arranged for sealing the inlet conduit elements 29 relative to each other while allowing the inlet conduit elements 29 to move relative to each other in the direction A for avoiding water to enter the inlet conduit 19 in a space that may be available between the inlet conduit elements 29.
- the coupling organs 47 are arranged for cooperating with protrusions 57 provided at an outer side of the inlet conduit elements 29 for maintaining the sealing gaskets 45 between neighbouring inlet conduit elements 29 while avoiding that the neighbouring inlet conduit elements 29 are separated from each other when increasing the length of the inlet conduit 19.
- the coupling organs 47 together with the protrusions 57 avoid, or at least significantly reduce the risk, of separating the inlet conduit elements 29 from each other when maximising the length of the inlet conduit 19.
- the protrusions 57 are formed as flanges.
- the swim mask 1 further comprises a connecting element 55 for connecting the assembly of inlet conduit elements 29 to the upper part 7 of the frame 5 and/or the visor 3 and/or the flexible skirt 9.
