Definitions

  • the invention refers to a diving mask with a transparent face plate for swimmers which keeps the water from the face of the swimmer and therefore encloses his mouth and eyes.
  • the mask is provided with a snorkel.
  • the British Specification 822,680 discloses a mask having its own inhaling tube and an exhaling tube which is isolated from the inhaling tube. Both tubes are connected with the inner space of the'mask by individual inlets, whereby the exhaling tube is extended into the inner space of the mask and ends in the mouth of the swimmer by means of a mouthpiece.
  • the tubes forming the snorkel outside of the mask may be concentric tubes. The result is a relatively expensive constructionbecause of-the individual extension of the breathing tubes through the individual inlets.
  • concentric tubes there is furthermore the complication that it is difficult to form these tubes into a U- shaped end as such U-shaped end is normally used in connection with a valve in order to avoid the flowing of water into the snorkel. Such a U-shaped end is also used in connection with the invention.
  • the object of the invention is to produce a mask in which the condensation of moisture on the transparent face plate is positively avoided.
  • Another object of the invention is to assure that the inhaled air contains only fresh air.
  • a mask with a transparent face plate which surrounds the eyes, nose and mouth and having attached thereto two separate breathing tubes which can be closed by a valve attached to a U-shaped end of a snorkel, an inhaling tube being directly connected to an opening in the mask and an exhaling tube which extends through the wall of the mask reaching the mouth of the swimmer wherein said exhaling tube is formed as a flexible pipe which extends from the mouth through the opening and into the inhaling tube and thus inside the inhaling tube through a U-shaped end of the inhaling tube where it ends just before the valve.
  • the pipe can be led along the side of the transparent face plate down toward the mouth.
  • it is suitable to fix the pipe in the inner space of the mask, for example, by means of an adhesive.
  • the pipe between the eyes along the nose toward the mouth if the snorkel extends from the middle of the mask. Since in this case the pipe is led perpendicularly in the middle of the mask between the eyes the view of the swimmer is not affected.
  • the pipe may be fixed by an adhesive.
  • the pipe is made from a flexible plastic This material mouthpiece at its end in the inner space of the mask in order to hold the pipe in the mouth without fatigue.
  • FIG. 1 is a cross-section through a mask with one snorkel extending from its center, and provided with a flexible exhaling pipe according to the invention
  • FIG. 2 is a view of the same mask in which the pipe is led through the middle to the mouth;
  • FIG. 3 shows the same mask with a pipe led along the side of the transparent face plate
  • FIG.'4 shows a mask with a snorkel extending from the side of tlie mask and a pipe which is led along the side of the transparent face plate.
  • the mask as shown in FIG. 1 comprises a housing 1 into which the transparent face plate is sealed.
  • the housing 1 is fixed to the head of the swimmer by means allows the fixing of 'a of the band 3.
  • the band is adjustable tight enough to provide a seal between the face of the swimmer and along the edge 4 against the water.
  • the snorkel 5 extends from the upper part of the housing 1.
  • the snorkel ends in its upper part in a U-shaped piece 6 from which the cage 7 is suspended in which there is a floating ball 8, for example, of plastic material which in case of diving with the mask is pushed upward, thereby closing the opening 9 of the U-shaped piece 6.
  • a flexible pipe 10 is introduced into the snorkel 5.
  • the lower end 11 of the pipe 10 terminates in the area of the mouth of the swimmer.
  • a mouthpiece 12 is attached to the end 1 l to simplify the holding of the end 11 in the mouth.
  • the inner cross section or diameter of the pipe 10 is large enough that breathing is possible without difficulties. Further, the pipe 10 leaves such a cross-section in the inner diameter of the snorkel 5 and of the U-shaped piece 6 free that through this cross-section breathing is likewise possible without difficulties.
  • the swimmer inhales through the nose whereby he breathes air in through the space which is left free by the pipe 10 inside of the snorkel 5 and the U-shaped piece 6.
  • the used air is exhaled through the mouth and through the pipe 10. Thereby the used air cannot enter the inner space of the mask so that condensation on the transparent face plate 2 is avoided.
  • the pipe 10 is free in the inner space of the snorkel 5 and the U-shaped piece 6. Generally, a fixing of pipe 10 is not necessary since the pipe 10 is held by friction in the bend at the lower end of the snorkel and the U- shaped piece 6. It is also possible to provide the pipe 10 with supports 16 in the snorkel 5 and the U-shaped piece 6. The pipe 10 terminates in the U-shaped piece 6 just before its ending 9 so that the ball 8 avoids possible entrance of water at the ending 9 in case of diving with the mask. On the other end it is achieved that the ex haled breath is led directly into the open air.
  • FIG. 2 is a front view of the mask as shown in FIG. 1.
  • the pipe 10 lies between the eyes of the swimmer above the nose so that it does not hinder the view of the swimmer.
  • FIG. 3 shows a different embodiment wherein the pipe 14 is bent to the side after entry into the inner part of the mask and extends along the side of the transparent face plate 2.
  • the view of the swimmer is here entirely free.
  • This construction may be preferable where the transparent face plate is not close to the face of the swimmer since then a pipe in the center and close behind the transparent face plate 2 might be found to be disturbing.
  • FIG. 4 shows a construction in which the snorkel is provided at the edge of the mask.
  • the snorkel 13 extends from the side of the housing 1 perpendicularly upward.
  • the pipe 15 is led correspondingly downward in a bend at the side of the transparent face plate 2 where it ends in the area of the mouth of the swimmer.
  • a diving mask having a housing providing a lower mouth area and an upper visual area in said housmg, a transparent face plate sealmgly attached to a first opening in said housing and covering at least said visual area, an outer breathing conduit and an inner breathing conduit extending concentrically within said outer breathing conduit, means for connecting one end of said outer breathing conduit to a second opening in said housing, a valve arranged for closing the other end of said outer breathing conduit, the improvement comprising a flexible hose forming as an exhaling conduit said inner breathing conduit, said flexible hose extending through said second opening in.said housing into said outer conduit, which outer conduit serves as an inhaling conduit, said flexible hose having a free, inner end extending within said housing from said second opening to said mouth area thereof, and an outer end located adjacent to said valve.
