Definitions

  • the invention relates to a diving device with an air supply line which is connected on the one hand to the atmosphere above the water level and on the other hand to the mouth of the device user.
  • Such a diving device is widely used in the form of a snorkel.
  • the advantage of snorkeling is its simplicity, its low price, the light weight of its equipment and the relative harmlessness of diving.
  • a disadvantage of snorkeling is the short diving time of about one minute by holding the breath.
  • the significantly more demanding compressed air diving is known as a much more complex alternative to snorkeling.
  • the advantage of compressed air diving compared to snorkeling is the possibility of free, independent swimming diving to depths of over 50 meters.
  • a disadvantage of compressed air diving is the limited diving time of about half an hour to two hours depending on the depth and device.
  • Compressed air devices are mechanically relatively complicated, heavy-weight and require a lot of maintenance and care.
  • the high pressure in the bottle of around 200 to 300 bar represents a constant danger.
  • the compressed air bottles must therefore be checked for rusting at regular intervals.
  • compressed air diving requires a good organization of the diver as well as some training and aids after the diver is constantly dependent on compressors or filling stations.
  • the invention is therefore based on the object of creating a simply constructed, flexibly usable and easily transportable diving device which can be used at depths of up to 10 meters and does not entail any limitation of the diving time.
  • an air pump which can be operated by muscle power is provided for supplying air from the atmosphere through the air supply line to the mouth of the device user, in that an actuating device connected to the air pump for actuating the air pump with one or more of the limbs of the device user is connectable or can be grasped by these, and that an air outlet which can be closed by means of an exhalation valve is provided for the exhaled air and which, as seen in the direction of flow of the air supplied by the air pump, is located behind the air pump.
  • the air pump can be fastened to the body of the device user by means of carrying straps or the like and is actuated via traction means such as belts or the like, which are connected in a suitable manner to the legs of the device user.
  • the device according to the invention is thus in principle a muscle-powered pump with which the diver himself, coupled with swimming movements, brings air through a hose under water and puts it under the pressure necessary for breathing.
  • the upper end of the hose leading upwards into the atmosphere is fastened to a floating body such as, in particular, an inflatable buoy, which is preferably designed as a diving signal buoy and holds the hose end above the water surface.
  • a floating body such as, in particular, an inflatable buoy, which is preferably designed as a diving signal buoy and holds the hose end above the water surface.
  • the air pump comprises a rigid outer body, the closed top of which is connected to the air lines leading on the one hand to the water surface and on the other hand leading to the mouth of the device user, and the open underside of which is closed by a flexible, bellows-like or sack-like part, which at external overpressure is pressed into the interior of the outer body while reducing the pump volume and is dimensioned such that it can essentially completely fill the interior of the outer body, the actuating device acting on this flexible part.
  • the air pump can be designed as a bellows which is dimensionally stable in cross section, the upper side of which is connected to the air lines and the lower side of which the actuating device engages.
  • the air pump can expediently also comprise a cylinder and a piston guided in the cylinder, the closed upper side of the cylinder being connected to the air lines, the lower side of the cylinder being open and the actuating device engaging the piston.
  • the bellows at the end of which two straps are attached, which carry foot stirrups at their ends, are released by the pressure of the water presses the rigid outer body in and sets the air there under the respective ambient pressure.
  • the air can be inhaled through the inhalation tube that opens at the closed end of the rigid outer body.
  • a valve at the inlet of the outlet hose prevents the air from flowing back to the water surface.
  • the inhaled air is breathed back into the inhalation tube, with another valve preventing the exhaled air from flowing back into the pump volume.
  • the exhaled air finally enters the water via an exhalation valve.
  • the air pump is preferably carried in front of the chest, which has the advantage that the pump volume is lower than the lung center when the diver is in an upright, horizontal or slightly upside down swimming position, which means that there is a slight overpressure in the pump volume compared to the lung volume, which in particular during physical exertion is perceived as pleasant when breathing.
  • the breath-movement cycle corresponds to Diving device according to the invention that of breast swimming.
  • the movement rhythm of the legs required to operate the diving device is therefore easy to learn, especially for breast swimmers.
  • the diving device according to the invention is usually applied on land. After getting into the stirrups, the diver can move freely without any noticeable disability, walk normally and jump into the water with his legs first.
  • ballast taring With correct ballast taring, one can bring about or support sinking and rising by cleverly coordinating the pumping and breathing activity, after the buoyancy of the diving device depends on the amount of air in the pump volume. Therefore, if the legs are not fully stretched so that the pump volume does not fill completely with air, the diver sinks down. In contrast, if the legs are fully stretched and the pump volume is completely filled with fresh air, the lift of the air pump increases and the diver increases.
  • the maximum pump volume of the pump is matched to a maximum immersion depth of about 10 meters, that in one breathing cycle the fresh air present in the pump volume is fully consumed, so that the pump volume of the air pump is preferably around 6 liters, the above loses the greater immersion depth Described method for influencing the sinking or rising in importance after the entire stroke range of the air pump is required in these greater depths to suck in sufficient air.
  • the length of the foot straps carrying the foot straps can be adjusted in particular via a quick-release fastener is.
  • the strap length can be adjusted individually so that he has the opportunity to stretch his legs fully during each actuation cycle, depending on the setting of the strap length in this extended state of the diver's legs the bellows or, more generally, the moving element of the pump need not be in the fully extended state, whereby the maximum pump volume can be controlled depending on the length of the belt.
  • the outlet side of the air pump is connected via a check valve to an additional flexible air reservoir, which in turn is connected to the mouth of the device user via a hose.
  • This air reservoir is preferably attachable to the body of the device user, for example by means of straps or the like.
  • Such an air storage container creates an independence between the leg movements of the diver and his breathing activity due to its buffering action, whereby the use of the device according to the invention can be further simplified.
  • Such an additional air storage container can be advantageous, in particular, at lower diving depths, at which the additional buoyancy of the air storage container does not yet have as great an effect.
  • the air pump can be actuated due to the diver's leg movements.
  • the air pump is actuated by the diver's arms.
  • the belt or rope connected to the movable part of the air pump is connected at its end to a suitable handle, in the simplest case in particular a rod, which can be gripped by hand on both sides.

  • the actuating device can expediently be formed by a Bowden cable.
  • the diving device according to the invention is extremely compact and fits, for example, in a medium-sized sports bag.
  • the outer, rigid, container-shaped body of the pump can be used as a container for accessories such as a mask, camera, knife etc. when the bellows is turned inside out.
  • the diving device according to the invention can also be used as a boat or yacht accessory, for example to carry out repairs or cleaning on underwater ships (e.g. changing propellers) or to look for lost objects in shallow harbor basins. Possible areas of application are wherever underwater activities in shallower water are occasionally necessary, but the purchase and maintenance of a compressed air device is not worthwhile. Furthermore, the diving device according to the invention could be interesting as a supplementary device for compressed air divers in order to save compressed air under certain conditions.
