Definitions

  • the scuba diver's equipment usually includes a half-face mask and one or two compressed air bottles, from which he receives the necessary breathing air via a bottle valve and an attached lung regulator.
  • a mouthpiece inserted into his mouth, which he holds firmly with his teeth. Since he can no longer close his lips, it is impossible for him to speak clearly.
  • the object of the invention is to create means which enable divers to communicate with each other at short distances.
  • the invention solves this problem with a mouthpiece that has the features of claim 1.
  • the mouthpiece according to the invention with membranes allows the diver to both breathe and speak, and the air-filled hose communicating with the mouthpiece and sealed at the end by the end membrane transmits the sound waves. If a second diver holds the latter membrane to his ear, he understands the speaker. It has been shown that this also works thanks to the hood belonging to the insulating suit.
  • the new mouthpiece and hose can be part of compressed air diving equipment, so that the diver can talk to a colleague during the whole underwater stay.
  • the mouthpiece with membranes can also be connected to a snorkel, the tube piece connected to the hose being at its free end through a membrane that optionally closes or opens the opening so that the diver can either breathe or speak.
  • the mouthpiece shown in FIGS. 1-5 differs from previously known mouthpieces in that it is provided with membranes which allow the user to speak. It comprises a connection pipe socket 1 which leads to a regulator (not shown in FIGS. 1-5). This pipe socket merges into two fork-shaped lugs 2, which are provided with bite cams 21 at their outer ends. On the side of the pipe socket there is a second connection socket 3 for a corrugated hose, which is connected to the cavity of the socket l.
  • the forked lugs are widened at 22 at their rear end.
  • the front part of the fork-shaped lugs is then covered with two membranes 4 on the nozzle 1.
  • FIG. 2 Only for the sake of clarity, the membranes in FIG. 2 are highlighted by a dotted surface. They end at the back in the area of a user's lips when the user has inserted the mouthpiece into his mouth.
  • the two fork-shaped projections 2 have an inwardly tapering cross-sectional profile, as shown in the sectional figures 4 and 5.
  • the entire mouthpiece is made of a relatively soft plastic or rubber elastomer and stiffened by means of steel wires 5 embedded in the plastic.
  • the dotted lines represent the closed position of the membrane 4.
  • a mouthpiece M according to FIG. 1 is assembled with an automatic lung regulator 6 and a rubber folding hose 7 which serves as a sound conductor and which is closed off by a membrane 8.
  • FIG. 6A shows the end membrane 8 on a larger scale, in section, with part of the corrugated hose 7 connected to it.
  • a pressure hose 61 leads to the regulator, which supplies air to the regulator via a (not shown) reducing valve from the (not shown) air supply bottles.
  • a distribution chamber 66 is connected to the exhalation valve 62 of the regulator, which allows the exhaled air to escape laterally so that the air bubbles do not obstruct the diver's view.
  • the distribution chamber is provided with small openings so that no large bubbles form. Figures 9 and 10 show such a distribution chamber, which will be described later.
  • a hook 71 is attached near the membrane 8, by means of which it can be attached to the pressure hose 61 when not in use, as is indicated by broken lines in FIG. 6 above.
  • FIG. 7 shows the use of a mouthpiece M 1 which is slightly modified compared to the mouthpiece according to FIGS. 1-5.
  • This mouthpiece.Ml corresponds in structure to the mouthpiece according to FIGS. 1-5 with the exception that it has no lateral connecting piece 3 .
  • the corrugated hose 7 serving as a sound conductor is connected to a distributor housing 64 for the exhaled air.
  • the hose 7 is connected to the right end of the housing 64 in FIG. 7, and a second exhalation valve 65 is connected to the left end so that air can escape but no water can penetrate the housing.
  • This exhalation valve is provided with a porous cap so that no large bubbles form.
  • the perforated cap is indicated by cross hatching.
  • FIGS. 1-5 Figure 8 finally shows a third use of the mouthpiece.
  • This mouthpiece M 3 corresponds in its essential structure to the mouthpiece according to FIGS. 1-5, only it no longer has a connection to a regulator, but instead a folding hose 7 is connected to the side of a nozzle, similar to the nozzle 3 a snorkel tube 9 leads.
  • an exhalation valve 65 is attached to the bottom of the mouthpiece, which allows both exhaling during S p raking and emptying the snorkel of water that has entered.
  • the outer end of the snorkel tube 9 is provided with a membrane chamber 10 which either releases or closes the tube end.
  • This chamber is shown in section in FIG. 8 A, in the position in which it closes the lateral openings 91 of the snorkel tube.
  • FIG. 8B shows the membrane chamber in the position in which it opens the openings 91 of the snorkel tube.
  • the diver When closed, with an air-filled snorkel, the diver can speak thanks to the new mouthpiece and briefly communicate with a colleague underwater.
  • the snorkel When open, the snorkel can be used as before.
  • FIG. 9 shows a usatemluft A distribution chamber 66, which corresponds to the chamber 63 shown in FIG. 6
  • FIG. 9 shows the chamber in section when it is used while speaking. This is because relatively little air is expelled during speaking and the chamber therefore remains about half filled with air. The air expelled during speech therefore escapes through the small openings 67 and many small air bubbles form which do not interfere with communication. If the diver takes a deep breath afterwards and then releases a corresponding amount of air, the water is displaced from the chamber 66 so that this larger amount of air can now escape unhindered through the lower large openings.
  • FIGs 11 and 12 show a simplified mouthpiece which is particularly suitable for use with a snorkel.
  • the membrane 40 directly connected to the pipe socket 100 has the shape of an oval piece of hose.
  • the pipe socket 100, the fork-shaped lugs 20, the bite cams 210 and the membrane 40 form a single piece, so that such a mouthpiece can be produced cheaply.
  • the closed position of the membrane is shown by broken lines.
  • FIGS. 14-16 show a variant of a mouthpiece according to FIGS. 1-5.
  • the fork-shaped lugs consist of a correspondingly bent, stainless steel wire 200, which is anchored in the pipe socket 1.
  • Bite cams 211 made of plastic are attached to the free ends.
  • the membrane 400 has the shape of an oval tube section which adjoins the pipe section 1 and comprises the fork-shaped lugs 200 made of wire on the outside.
  • the mouthpiece differs from the previously common mouthpieces by the membrane integrated with it, but the inhalation and exhalation takes place as before.
  • the mouthpiece Compared to the previous mouthpieces, however, it has the great advantage that the lip movement moves the membrane and that it is possible to speak clearly. Since the mouthpiece enables normal breathing, as mentioned, it can also be used for so-called alternate breathing.
  • the diver will then, as with the alternating breathing described above, remove the normal mouthpiece connected to the regulator and insert the mouthpiece of the snorkel so that he can speak to a colleague in the diver.
  • the prerequisite for this is, of course, that the membrane chamber is closed and the water in the snorkel has been blown out.
  • FIG. 13 shows a use of this type.
  • the mouthpiece M 4 used corresponds to that according to FIGS. 11 and 12.
  • the hose 7 of the snorkel is connected to the mouthpiece M 4 via an intermediate piece provided with a valve 65.
  • the diver on the right tells his colleague something on the left.
  • the membrane chamber 10 is placed on the ear of the listener.
  • the equipment either includes the new mouthpiece connected to the regulator, with sound conductor, hose and membrane or consists of normal equipment with regulators and an additional snorkel with the new mouthpiece, membrane chamber and exhalation valve.
  • the equipment can include both elements. This would allow a diver equipped in this way to have a mutual linguistic communication with a colleague who only has normal, previous equipment.
