Definitions

  • the subject of the invention is a snorkel mask according to the preamble of claim 1.
  • Such a snorkel mask is, for example, with the subject matter of EP 3 153 400 A1 known.
  • the snorkel mask shown there has a snorkel for the separate guidance of the inhaled and exhaled air.
  • the inhaled air is fed into the half mask from a supply air duct arranged in the snorkel via the interior of the visor via check valves arranged in the half mask on both sides.
  • the exhaled air is guided through duct sections of a blow-out duct adjoining the side of the half mask into a U-shaped profiled groove in the edge area of the visor, which is open on one side.
  • the blow-out channel in the visor which is open on one side, is sealed by covering the blow-out channel on the visor side with an opposite U-profile of the rubber-elastic face seal.
  • the one-sided, U-shaped profiled receiving groove in the edge area of the visor forms a sealed connection with an associated, oppositely directed U-shaped air guide profile of the rubber-elastic face seal around a self-contained blow-out channel for guiding the exhaled air in the direction of the connected snorkel to form.
  • the fitting of the visor-side U-shaped receiving groove into the oppositely directed U-shaped air guiding profile in the face seal did not lead to a reliable sealing of the blow-out duct. It could therefore happen that the exhaled air unintentionally in at the sealing points of the interlocking U-profiles reached the interior of the snorkel mask and mixed with the inhaled air.
  • Figure 5 of the cited publication provides that the blow-out channel is formed directly in the profile of the face seal, which, however, is associated with a high level of effort in the production of the face seal because a plastic with different material hardness is used and thus the connection between the visor , the mask frame and the face seal thus made is difficult.
  • FIG. 6 of this publication a cylindrical hose is additionally drawn into the hollow profile of the face seal according to FIG. 5 in order to avoid the risk of inadvertent compression of the profile of the blow-out duct according to the previous embodiment.
  • the US 2016/0297505 A1 shows another guide of a blow-out duct.
  • the blow-out duct designated there by the reference numerals 100, 200 is guided in its upper area outside and above the face seal (see FIG. 9) in the mask frame.
  • the mask frame forms two opposing connection openings in its central area.
  • a rubber-elastic connection channel which is part of the face seal, is connected airtight to each connection opening. This connection channel is air-tightly connected to the interior of the rubber-elastic half mask.
  • the two-armed blow-out channel formed in this way in the face seal is accordingly fixed to the mask frame with separate connecting means, which is associated with an additional high level of effort.
  • blow-out channel on the mask side has to be designed as a self-contained hollow profile, which is only possible with the use of additional drawing cores when manufacturing the mask frame in a plastic injection molding tool.
  • the invention is therefore based on the EP 3 178 735 A1 and the EP 3 153 400 A1 the object is to develop a snorkel mask of the type mentioned in such a way that an inexpensive and reliable guidance of the blow-out channels of the snorkel mask with a large air cross-section with low exhalation resistance is provided in an operationally reliable manner.
  • the invention is characterized by the technical teaching of claim 1.
  • a preferred feature of the invention is therefore that it was recognized that the from EP 3 178 735 A1 known air ducts are not reliably sealed, because especially in the embodiment according to Figure 4 of the EP 3 178 735 A1 It could happen that the seal between the receiving groove in the visor and the face seal sealing this receiving groove did not seal evenly over the circumferential length, which was associated with the disadvantage of mixing the exhaled air with the inhaled air in the interior of the visor.
  • the air ducting hose according to the invention can easily be inserted into one U-profile in order to then plug the two U-profiles into one another and connect them to one another.
  • an air guide tube with a significantly smaller diameter compared to the diameter of the profile on the face seal side could be used. This, however, has the disadvantage that the exhaled air can only be pressed out via the air-guiding hose with a reduced diameter, which results in increased exhalation resistance.
  • an air ducting hose with a diameter that is matched to the round profile on the face seal side it can only be pushed into the closed profile of the face seal over a greater length by overcoming greater frictional forces.
  • the profile of the air guide tube is adapted to the profile of the visor-side air guide profile, which is associated with the advantage that the exhaled air can be blown out through a large outlet cross-section.
  • the profile of the visor-side air duct is rectangular or square
  • the profile of the air-guiding hose is also adapted to such a profile and the air-guiding hose can be inserted into the profile of the visor-side air guiding profile essentially free of play and in a form-fitting manner during assembly. This ensures reliable assembly and low exhalation resistance.
  • the lower connection end of the air duct is connected to the interior of the half-mask and its upper connection end is connected to a blow-out duct in the snorkel tube.
  • the exhaled air which is guided via the air duct according to the invention, no longer flows into the snorkel tube and a snorkel connected to it, but that the exhaust end of the air duct in a U-profile on the visor side or in a Mask frame arranged, valve-supported exhaust opening opens.
  • valve-supported blow-out openings arranged on the visor-side U-profile and / or on the mask frame offer less exhalation resistance because of the shortened length of the exhalation paths.
  • a flap- or spring-loaded one-way valve arranged there must ensure that water does not inadvertently penetrate through the blow-out opening into the air duct or blow-out channel used to guide the exhaled air.
  • claim 4 proposes an air duct according to one of claims 1 to 3, proposes the independent claim 5 according to the 2nd alternative for solving the same problem (reducing the exhalation resistance) any form of a blow-out channel, either after the EP 3 178 735 A1 can be formed in a self-contained profile between the face seal and visor or according to the subject of the US 2016/0297505 A1 as an exhalation tube according to the 1st alternative, which is embedded in the face seal and / or in the mask frame and guided there.
  • the second alternative all shapes, designs and profile shapes of blow-out ducts are claimed, the length of which is shortened according to the invention in order to ensure a lower exhalation resistance.
  • the independent claim 5 provides an exhalation channel formed in the face seal according to FIG EP 3 153 400 A1 to use for guiding the exhaled air, whereby all the exemplary embodiments have in common that the blow-out opening for the breathing air is no longer arranged in the snorkel tube and in the snorkel connected there.
  • the length of the blow-out duct is shortened in length because there are one or more blow-out openings arranged on the side of the snorkel mask, each of which is protected from the ingress of water by a flap or spring-loaded non-return valve.
  • the Figure 1 shows schematically a snorkel mask 1 in section, which essentially consists of an elastic face seal 3 ', which is elastically applied to the face of the user - viewed over the entire circumference - in a sealed manner, the interior 21 of the snorkel mask 1 being at least partially transparent visor 2 is completed, on the peripheral circumference of which a U-profile 4a is formed as one part of an air guiding profile 4 for guiding the exhaled air 19.
  • another U-profile 3c is used, which is formed on the edge side of the face seal 3 'and which engages over the U-profile 4a of the visor 2 in a sealed manner with two opposing and approximately parallel profile legs 3a.
  • Sealing points 5 are formed by the interlocking of the two U-profiles 3c, 4a, so that according to FIG EP 3 178 735 A1 In the interior of the air guide profile 4, a blow-out channel 20 for the exhaled air 19 is formed.
  • the sealing points 5 were not always reliably sealed, so that it could happen that the exhaled air 19 could inadvertently get from a non-functioning sealing point 5 into the interior 21 of the snorkel mask 1.
  • FIG Figure 1 provides that an air guide tube 6, which is adapted to the shape of the air guiding profile 4 on the visor side, is inserted in the direction of arrow 9 into the air guiding profile 4 on the visor side in FIG Is pushed in longitudinally or inserted from above, so that the function of the sealing points 5 is no longer important.
  • the exhaled air then flows in the direction of arrow 9 through the interior 7 of the air guide tube 6.
  • the Figure 2 shows schematically a snorkel mask 1 with a view of the inside, where it can be seen that a half mask 10 is sealed to the face seal 3 'and the half mask 10 is used to absorb the inhaled and exhaled air because it is sealed to the mouth and nose area of the user.
  • the inhaled air is introduced into the half mask 10 in the direction of arrow 23 via the interior 21 of the visor 2 via two lateral check valves arranged in the half mask.
  • the exhaled air 19 is guided through lateral, lower openings in the half mask 10 into lateral air-tightly adjoining blow-out channels of the face seal 3 'and the air guiding profile 4, 4a of the visor in the direction of the upper snorkel tube 4.
  • an outlet valve 11 for discharging water lying in the half mask 10 is also shown.
  • the air guide hoses 6 according to the invention - as in FIG Figure 1 - are inserted in the interior between the mutually assigned U-profiles 3c and 4a, the lower connection end 12 being connected to the half mask 10, while the upper connection end 13 opens with a connection end 13 into a blow-out channel 15 in the snorkel tube 14.
  • a central supply air duct 16 is also arranged in the snorkel tube 14.
  • FIG. 3 now shows in connection with the Figures 1 and 2 - but also in isolation with regard to the independent claim 5 - an embodiment in which the respective air ducting hoses 6 are not with their upper Connection ends 13 open into the snorkel tube 14, but that exhaust openings 18 are arranged laterally on the visor 2 and / or on the mask frame 22, each of which is assigned a spring-loaded check valve 17.
  • an enlarged cross section can be made available for the supply air ducts 16, which reduces the inhalation resistance for inhaling the fresh air.
  • a larger amount of inhaled air can be introduced via the snorkel into the interior space 21 of the snorkel mask 1.
  • the Figure 4 shows on its own and / or in combination with the Figures 1 to 3 schematically and in general form that a blow-out channel with a shortened length can be provided to reduce the exhalation resistance.
  • blow-out duct is guided in the visor 2 or in the sealing device 3.
  • the only decisive factor is that the exhaust air 19 is no longer guided as far as the snorkel tube 14, but only up to half or two thirds of the height of the visor 2, in order to be blown out there via valve-supported exhaust openings 18 on the side.
  • blow-out channel 20 is designed in the visor and / or in the sealing device 3 and / or in the mask frame 22.
  • the shortened length of the blow-out channel 20 is important, which considerably reduces the exhalation resistance.
  • blow-out channel 20 can be designed as a partially in the sealing device, closed channel after the EP 3 153 400 A1 be formed, which is connected in the lower third of the snorkel mask with an edge-side, formed in the visor, closed channel.
  • the length of the blow-out channel 20 is shortened, because the blow-out channel 20 already ends at about half to 2/3 of the height of the visor in the side, opposite blow-out opening.
  • the length of the exhalation path is significantly shortened because a guide over the entire circumference of the mask frame up into the snorkel tube arranged on the mask frame is no longer necessary.
  • one or two blow-out openings are arranged laterally in the lower part of the snorkel mask 1 at the height of the chin of the user. This corresponds approximately to the height of the half mask 10. A bubble curtain formed from the air bubbles of the exhaled flow should not sweep over the visible part of the visor.
