Definitions

  • the invention relates to a diving device according to the preamble of claim 1, consisting of an air supply line ending above the water level in the atmosphere, of an air pump carried by the diver and operated by muscle power with a defined pump volume and a rigid housing on which a flexible, for changing of the pump volume serving part is attached and to which the other end of the air supply line is connected via a first check valve, which opens during the suction process, from a mouthpiece, which via a hose line and via a second check valve, which opens when the pump volume is overpressure in relation to the internal lung pressure is connected to the pump volume, and from an exhalation valve arranged between the second check valve and the mouthpiece for exhaling the air into the water, the actuating device acting on this flexible part.
  • Diving devices which have an air pump which is connected to the body of the diver and can be actuated by muscle power, with the aid of which the air is sucked in from the atmosphere via a check valve, compressed and fed to a mouthpiece via a further check valve. Exhale via a separate exhalation valve.
  • Such diving devices can be used for diving depths of up to approx. 10 meters and are characterized by their simple construction and correspondingly low manufacturing or acquisition costs.
  • the 10-meter range is of particular importance for scuba diving, since diving can be carried out to this depth without any health risks and there is usually still good visibility.
  • the considerably more complex compressed air or oxygen devices are required, which also require appropriate training in order to be able to counter the loads and hazards arising from the high water pressure.
  • a bellows is arranged within a fixed housing, which is stretched for sucking in air from an air supply line connected to the atmosphere by means of two hand levers. After completion of the suction process, the water pressure acts via openings in the housing on the outer wall of the bellows facing the housing wall and compresses it. The air inside the bellows is fed to the mouthpiece at the pressure corresponding to the water depth and can be inhaled by the diver.
  • the known diving device must be held in front of the diver's face with the mouthpiece and the hand levers and therefore restricts the diver's view and mobility. There is also a horizontal position of the pump, as it It is common to see the danger that the buoyancy of the extended or filled bellows presses it against the housing, thereby restricting or preventing its free movement.
  • Another diving device known from US Pat. No. 3,050,055 is carried on the back and has one or two piston pumps, the pistons of which are under the action of return springs.
  • the piston pumps have only a comparatively short stroke and have to be actuated several times, preferably with the diver's feet, in order to fill an air reservoir required as an additional part with a sufficient air reservoir.
  • the invention has for its object to provide a simply constructed diving device, the flexible part defining the pump volume ensures reliable suction and compression of the air over the entire diving depth range of the device, the interior of the housing should be essentially completely usable as a pump volume.
  • the housing then has an opening which is closed by the flexible part.
  • the flexible, bag-like part is moved out by muscle force against the water pressure, so that an increase in volume takes place inside the housing.
  • the water pressure pushes the flexible part back into the interior of the housing, the flexible part gradually coming into contact with the inner wall of the housing due to its sack-like configuration and ultimately essentially completely filling it.
  • the device is preferably carried so that the air pump is below the diver's lung center. Due to this arrangement, the air in the housing has a slight positive pressure compared to the internal lung pressure, which is just sufficient to compensate for the resistance of the flexible part and the inhalation valve, so that a pleasantly low breathing resistance is achieved.
  • a particularly compact and handy design is achieved if the valves are arranged in a common valve housing.
  • the flexible, bag-like part can be actuated via belts either with the feet or with the aid of an actuating rod with the hands or by a combination of both types of actuation.
  • the diving apparatus comprises an air pump, designated overall by reference number 10, an actuating device for the pump 10 and air lines 14 and 16.
  • the upper end of the air supply line 14 is held in an inflatable buoy 20, which is designed in particular as a diving signal buoy in order to warn approaching boats and to mark the dive site.
  • the buoy 20 can be used in the event of incidents in the manner of a lifebuoy, for which purpose loops and the like, which are not shown in detail, can be attached to the buoy 20.
  • additional fastening means can be provided on the buoy 20 in order to attach the air pump 10 when not in use or when changing a diver to latch on, thereby avoiding that the diver must first climb into the boat together with the device.
  • the diving device is buoyant when the bellows is pulled out and fixed.
  • the length of the air supply line 14 limits the maximum depth. Markings on the hose can serve as a simple depth gauge.
  • the air supply line 14 can also be used as a signal line, as a "buddy line” (coupling the buoys of two divers so as not to lose contact with one another when the view is cloudy) or for control purposes (breathing noise heard on the surface).
  • the hose 16 which is also designed as a flexible pressure hose, leads from the air pump 10 to a mouthpiece 18 which the diver holds in the mouth when using the diving device.
  • Detachable hose connections 22, 24 are also provided near the buoy 20 and near the air pump 10, in order to enable the hose section located therebetween to be exchanged in accordance with the hose length required in each case. Additional weights for stabilizing the buoy in an upright position are also provided on the buoy 20 or on the hose.
  • the pump-near end of the air supply line 14 is pushed onto a connecting piece 26 which is formed on a screw ring 28 which is screwed onto a screw connecting piece 32 formed on the upper side of the pump housing 30 and projecting outward.
  • a cylindrical support element 34 is held between the outer edge of the screw connection 32 and the screw ring 28 and has an inwardly projecting annular surface 36 on its inside facing the pump, on which a compression spring 38 is supported.
  • the other end of the compression spring 38 is connected to a disk-shaped sealing element 40 which, due to the force of the compression spring 38, is pressed sealingly against an annular sealing surface 42 running at the inner end of the connecting piece 26.
  • the first check valve 44 formed by the arrangement described above is thus regularly closed, but opens as soon as the pressure in the air supply line 14 exceeds the pressure in the pump volume 46 of the air pump 10 by a certain amount.
  • the end of the hose 16 opposite the mouthpiece 18 is pushed onto a connecting piece 48 which is formed on a screw ring 50.
  • the screw ring 50 is screwed onto an intermediate piece 52, which in turn is screwed onto a further screw connection 54, which projects outwards and is formed on the upper side of the pump housing 30.
  • the intermediate piece 52 forms, together with the screw ring 50, a cylindrical chamber 56 which has two opposing ring surfaces 58, 60 which extend in the radial direction.
  • On the ring surface 60 facing the pump there is a disk-shaped sealing element 62, which is prestressed into its sealing position by means of a compression spring 64.
  • the compression spring 64 is supported on the one hand on the sealing element 62 and on the other hand on the ring surface 58.
  • the second check valve 66 formed by the arrangement described above is thus regularly closed, but opens as soon as the pressure prevailing in the pump volume 46 exceeds the pressure in the hose 16 by a certain amount.
  • the intermediate piece 52 further defines on its outer side an annular surface opposite the annular surface 60, a plurality of air outlet openings 68 connecting the chamber 56 to the external environment.
  • a sealing ring 70 rests against this outer ring surface and closes the openings 68.
  • the sealing ring 70 is pretensioned into its sealing position under a certain pressure by means of a compression spring 72 which is stretched between the outer surface of the sealing ring 70 and the opposite wall of the pump housing 30.
  • a compression spring 72 which is stretched between the outer surface of the sealing ring 70 and the opposite wall of the pump housing 30.
  • exhalation valve 74 is implemented in a somewhat different way in the case of the illustration according to FIG. 1. There is a branch in the hose 16, which can be closed by means of an exhalation valve 74 designed as a check valve.
  • two shoulder straps 77, 78 are attached, which are designed so that the pump 10 is worn by the diver on the chest. If necessary, an additional waist belt, not shown, can be used.
  • the open edge of a flexible part 76 is fastened to the lower edge of the housing 30 of the air pump 10.
  • the bag-like flexible part 76 can consist of a suitable rubber material, for example reinforced by a fabric, or of a rubberized fabric. The material must be airtight, watertight, flexible and sufficiently strong.
  • the size and dimension of the flexible part 76 corresponds essentially to the size of the pump housing 30. In particular from FIG.
  • the flexible part 76 is attached to the lower edge of the pump housing 30 by the lower edge 79 around the lower edge 80 of the pump housing 30 is turned outwards and a clamping ring 82 is pushed onto the lower edge 80 of the pump housing 30 from below such that the part 76 is securely clamped between the clamping ring 82 and the pump housing 30.
  • a buckle 84 is fastened, in particular adjustable in length, on which a belt 86 is carried.
  • the belt 86 is shaped at its two end regions via straps 88 to form foot straps 90 and is length-adjustable in each case via buckles 92.
  • the length of the belt arrangement will be set such that the flexible part 76 is practically completely pulled out of the pump housing 30 when the diver is standing upright.
  • the belt arrangement is long enough to be able to adjust it so that the part 76 is only partially pulled out of the pump housing 30 when the diver is standing upright.
  • a quick-release fastener of a known type, not shown, can be provided, which enables a quick and reliable change in the belt length with a handle.
  • the flexible part 76 In operation, due to the water pressure, the flexible part 76 is pressed almost completely into the pump housing 30 with the diver's legs bent. If the diver now stretches his legs, the part 76 is pulled out of the pump housing 30, as a result of which a negative pressure is created in the pump volume 46 defined by the pump housing 30 and the part 76, which causes the first check valve 44 to open through the air supply line 14 fresh air is sucked into the pump volume. As soon as the diver then bends his knees again, he can breathe in the fresh air drawn in through the hose 16 while opening the second non-return valve 66 while simultaneously reducing the pump volume. The exhalation takes place approximately when the legs are stretched, the exhaled air being exhaled outwards into the water via the exhalation valve 74.
  • Exhaling and filling the pump volume with fresh air by stretching the legs corresponds to normal breathing and Rhythm of movement when swimming with the breast so that the operation of the diving device is easy to learn.
  • the amount of fresh air drawn in can also be easily adapted to the respective need for breathing air.
  • a cable can also be provided for actuation, which is fastened to the flexible part 76 instead of the belt 86.

If the attachment on the side of the body opposite the air pump, i.e. generally on the back, there is a particularly favorable distribution of the force to be applied by the diver.
  • the pump housing can be made from any suitable material, but preferably from plastic.
  • the required lead ballast can be attached at a suitable point on the pump housing.
  • the lead ballast can be replaced by rigid or flexible containers which can be attached to the pump housing on both sides and which can be filled on site with suitable ballast such as stones, gravel, pebbles, sand or the like.
  • FIG. 5 shows an embodiment of a diving device which can be operated by hand.
  • the structure of the device corresponds essentially to that of FIG. 1, but instead of the belt arrangement 86 with foot straps 90, a short, length-adjustable belt 142 is provided, at the lower end of which a rod 144 is fastened in the middle.
  • the length of the belt 142 is preferably set such that when the bellows 76 is pressed completely into the interior of the pump housing, the gripping rod 144 bears against the lower edge of the pump housing 30.

  • the height of the pump housing can be 23 cm and the maximum stroke can be approximately 50 cm.
  • FIG. 6 shows a diving device similar to FIG. 1, but this is additionally equipped with a rod similar to FIG. 5.
  • the rod 146 shown in FIGS. 7 and 8 in plan and side view is a steel tube with a centrally arranged deflection roller 148 which partially surrounds a housing part 150 of the rod 146 in such a way that a rope 152 guided around the deflection roller 148 does not come off the roller 148 can slide down.
  • This rope 152 is fastened at one end to the upper fastening point 154 of the foot belt arrangement 86 and at the other end to a fastening point 156 at the lower edge of the pump housing 30.
