Definitions

  • the invention relates to a two-part wet suit according to the preamble of claim 1.
  • Such a wet suit usually consists of diving pants, e.g. a long john, and a diving jacket.
  • the diving jacket usually has a crotch for fastening between the legs and a longitudinal closure.
  • This suit on the cuff and collar areas on the one hand cannot be sealed so tightly that the penetration of the water is prevented.
  • no pressure is built up between the inner surface and the diver, which prevents water from entering the suit.
  • a known two-piece wet suit is designed with an integrated hood and crotch, where neoprene is used as the material.
  • the longitudinal closure of the diving jacket provided there runs diagonally from the chin or cheek area over the chest opposite lower edge of the diving jacket.
  • This well-known two-piece wet suit has no rescue and buoyancy system, so that it no longer meets the latest safety requirements.
  • wet suits are also known as one-pieces. These one-piece wet suits can have a buoyancy control system in the chest area, possibly also in the trunk area.
  • the longitudinal closure of this one-piece wet suit runs in the middle of the chest area from the chin area of the integrated hood to the crotch area.
  • such a one-piece wet suit can have a connection for a corrugated tube with a mouthpiece and a pressure relief valve.
  • the foldable hose and the mouthpiece serve to be able to apply different pressure to the buoyancy control system provided in the chest or trunk area.
  • buoyancy area in the chest area is divided in the middle by the zipper and is almost limited to narrow, longitudinally running buoyancy areas by the fastening areas for the zip fastener and by chest side seams.
  • tare area is understood to mean the area areas that can be used as tare volume. These areas of buoyancy area are usually double-layered and closed, so that a buoyancy volume dependent on the applied inflation pressure can be generated between the air-impermeable two layers.
  • a different tare volume is particularly necessary for deeper dives in order to balance the volume compared to the greater compression pressure to be found at higher depth on the material and the T, at least in some areas and to be able to set a desired buoyancy behavior for the diver.
  • buoyancy zones Another important aspect of the buoyancy zones is to use these buoyancy zones at the same time as a life jacket. Since in emergencies in which the diver uses the buoyancy zones as a life jacket, fainting cases must also be taken into account, there is a demand for a higher buoyancy volume in the chest area. This is to ensure that when the child is faint, the nose and mouth area points away from the water surface to enable breathing even in a coma.
  • the aforementioned one-piece Nrusttauchaners one hand ensure no sufficient Rettun g swestenetztrieb in the chest area. This is due to the central attachment of the longitudinal zipper. On the other hand, they are usually not to be put on or taken off by the diver alone without outside help. This is due to the fact that even with wet suits a very tight fit of the suit is required to prevent water circulation. This leads to an uncomfortable fit of the suit and the need for the help of a second person when putting on and taking off. In addition, this one-piece wet suit offers relatively poor thermal insulation, since only two layers of neoprene in the buoyancy zone. available. In the case of a buoyancy system provided on the fuselage, the central zipper provided on the chest side displaces the buoyancy volume and the intended compressed air into the side areas and into the back area, which means that the divers are not protected against passing out more is guaranteed.
  • dry suits are also known in diving.
  • a seal is generally created in the cuff areas, so that by inflating the dry suit from the outside, an air cushion can be created between the diver and the inner surface of the suit, which provides thermal insulation and can also be used for buoyancy purposes.
  • these dry suits Due to the sealing measures on the extremities and in the facial area, these dry suits are designed as one-piece.
  • they usually have a closure arrangement as a zipper. The course of the zipper can be guided on the front of the suit from the hip or thigh area to the shoulder. From there the zipper is led over the neck shoulder area to the other shoulder side and from there down to about half the chest height.
  • the area in the chest area can be designed as a life and buoyancy aid.
  • the neck area only an extremely narrow life vest collar remains, which can be connected to the connection of a corrugated hose and can have a pressure relief valve.
  • the back of this drysuit with buoyancy control has no additional buoyancy area. As a result, it is only possible to tare in the chest area or the entire internal pressure in the dry suit has to be applied or compensated, which requires more air and can be regulated less precisely for buoyancy purposes.
  • the invention has for its object to overcome the aforementioned disadvantages of these suits and to create a two-piece wet suit that meets the high safety requirements even for greater diving depths I and easily and without the help of a second person is extendable and should be inexpensive and versatile.
  • the essential idea with regard to an inexpensive and easy-to-use wet suit is to provide a two-piece in whose diving jacket a large-scale buoyancy system is integrated on the chest and back.
  • the ease of use when putting on and taking off is achieved by arranging the longitudinal closure in the side area, in particular from the armpit to the lower edge of the diving jacket. As a result, no interruption or separation of the breast area is required, which results in a large-scale chest-side buoyancy system.
  • the taring surfaces themselves are usually formed from two layers of neoprene, which are glued or welded in the edge area.
  • the primary neoprene material used for the wetsuit is usually double-laminated.
  • an inexpensive diving jacket is created that can be combined with a trouser part, e.g. can be combined with a Long John.
  • the two-part design also allows a relatively short longitudinal fastener, in particular a zipper, to be attached between the armpit and the lower edge of the diving jacket, which enables the diver to put on and take off independently without outside help.
  • the rescue and buoyancy system provided in the diving jacket in this way can advantageously be inflated by the diver himself via a corrugated hose that leads to the chest area.
  • the folding hose is connected to the neck area of the buoyancy control system via a connection and a quick stop device.
  • a pressure relief valve is provided in the neck area, which can be adjusted to a maximum pressure.
  • buoyancy system With this buoyancy system it is possible for the diver to create a volume balance in the buoyancy system at greater depths, which enables him to make an optimal dive. Since the dives are carried out to greater depths with compressed air or breathing bottles, there is a greater weight in the back area on the buoyancy area there. When the entire buoyancy control system, which is advantageously integrated over the shoulders, is inflated, the diver always receives a higher buoyancy in the chest area.
  • the front is in the area of the buoy
  • a pocket for a small compressed air emergency bottle is provided in a place that is easy to handle.
  • An appropriate connection for this emergency bottle enables the diver to pressurize the buoyancy control system in critical cases.
  • the primary pressure is generated over a large area in the chest area of the buoyancy control system, so that the diver is guided to the surface of the water in a faint-proof position and held there.
  • a signal strip with luminous or reflective coloring is always provided on the integrated hood in the middle, which ensures that the diver's head area can be easily recognized.
  • a zipper is preferred primarily because of its robustness and tight seal
  • other types of fasteners such as Velcro fasteners, double overlap snap fasteners, or the like can be used.
  • Materials other than neoprene can also be used as materials, the primary focus being high elasticity, water and air impermeability, light weight and good processability.
  • Fig. 1 shows the front view of a diving jacket 1 of a two-piece wet suit.
  • the diving pants e.g. a long john
  • the diving jacket is made in one piece and consists of a chest and back area with molded arms 4.
  • a hood 2 Integrated on the vest is a hood 2, which has a signal strip 19 running in the middle of the head from the forehead to the neck area in bright or reflective colors, e.g. Signal red, incorporated contains.
  • the diving jacket 1 is e.g. made of a neoprene material with double-sided lamination.
  • a crotch 9 is formed on the lower area of the back of the diving jacket 1, which is folded forward in the diver's crotch and can be fastened to the lower area of the chest area of the diving jacket 1 by means of a fastener 13 and locking holes 14.
  • the arms 4 have cuffs 5 to ensure a good closure, since the diving jacket 1 must also fit relatively closely, so that water circulation between the body of the diver and the inner surface of the diving jacket is prevented.
  • the diving jacket 1 is equipped with a large-scale buoyancy area 10 on the chest side.
  • the longitudinal closure is designed as a zipper 8, which is approximately on one side runs from the armpit 7 to the lower edge of the vest 3.
  • the breast-side taring surface 10 is approximately like a life jacket or shirt-like in plan view, an integrated taring system with the back part being created via a shoulder connection 12 on both sides.
  • the back-side taring surface 11 is also formed over the entire surface and extends from the neck area to the area of the lower edge 6 of the diving jacket 1.
  • connection 21 in the back neck area 22 possibly with a quick stop, for a folding tube 17.
  • This folding tube 17 is guided from the neck area to the chest area and has a mouthpiece 18 at the end which the diver can use to determine the intermediate volume of the buoyancy control system. All that is required for this is to inflate the buoyancy control system via the mouthpiece 18.
  • a pressure relief valve 20 also provided in the neck area ensures that excessive pressure cannot occur in the buoyancy control system.
  • an insertion pocket 15 for a compressed air emergency bottle is provided on the chest side of the taring surface 10 and can be connected to the taring system via a connection 16.
  • the normally small-volume emergency bottle not shown, enables the diver to apply compressed air to the rescue and buoyancy control system in emergencies, so that it is carried to the water surface without further action. Since breathing bottles are normally carried on the back part, the volume there through the buoyancy area 11 formed taring system is reduced, so that the greater lift is present on the breast side.
  • the buoyancy areas 10, 11, 12, which can be used as a life jacket, are e.g. made of a double neoprene layer, which is only glued or welded in the edge areas.
  • the volume formed between the two neoprene layers can be changed via the connections 21 or 16. Since the connection between the chest-side taring surface 10 and the back-side taring surface 11 is only worked out via the shoulder connections 12, buoyancy volume formation in the side areas is avoided and a defined buoyancy position is set on the chest and back.
  • the arrangement of the zipper 8 on the side allows a large, coherent buoyancy volume to be formed on the chest or belly and back sides, which can include a volume of between 20 and 30 l, in particular 22 l.
  • the areal relation between the chest and backside buoyancy area is expediently designed, even without considering the breathing bottles, in such a way that a larger chest buoyancy area is achieved.
