Definitions

  • valves are dimensioned in terms of size and the forces required to open them so that normal snorkeling breathing without mechanical assistance is possible when diving into snorkeling depth.
  • a sleeve 63 is inserted, which serves as another, second sleeve for the Bowden cable 11. Accordingly, the sleeve 15 is fastened to the sleeve 63 while the cable 17 passes through it.
  • the rope or wire 17 is centrally fastened to the piston 37 via a fastening part 65, which in turn is integrally connected to the piston 37.
  • an annular floating body 77 is connected so that it holds the housing with its longitudinal axis substantially perpendicular when the floating body and housing are immersed in the water 79.
  • the buoyancy achieved by the float 77 is calculated so that at least the air inlet opening 49 of the housing, but preferably also the opening of the sleeve 63 in the space 43, is kept above the water level when the buoyancy body 77 by the weight of the pump 33, the Hose 59 and the Bowden cable 11 is loaded.
  • the air outlet is designed as a mouthpiece 99, as are known from snorkeling or compressed air devices.
  • an exhalation valve designated overall by 101, is provided in the area of the hose 59 in the vicinity of the mouthpiece.
  • the feet of the diver in the loops 27 move away from the sacrum and pull the roller shackle 21 away from the plate 5 attached to the belt 1 via the rope 25.
  • the Bowden cable wire 17 attached to the roller shackle 21 is pulled out of the sleeve 9 and moves relative to the sheath 15 of the Bowden cable.
  • the Bowden cable wire 17 thus pulls the respective piston 37 downward over the fastening part 65 or the sieve plate 87 and the tube 85 acting as a piston rod, i. H. in the pressure direction of the pump.
  • the force to be applied corresponds approximately to that which is to be applied during leisurely cycling. Due to the increasing power requirement and / or increasing stroke (by reducing the diameter of the piston to reduce the required force), the radius of action is also limited in depth.
  • Bowden cable and tubular feed part are therefore expediently dimensioned so that there is a maximum immersion depth of 2 to 3 m, during which the air inlet opening has not yet been drawn under water by the train and thus further air intake is made impossible.
  • the buoyancy of the float 77 is dimensioned such that deeper diving than the length of the connection to the surface is not possible under the diver's own strength and thus the air intake opening cannot be accidentally pulled under water.
  • the force to be exerted by the legs acts as a counterforce on the sacrum via the Bowden cable, which, however, is well able to absorb this force due to the construction of the belt.
  • the construction shown in the exemplary embodiment enables the diver to move through the movement of putting on and pushing off the legs, which can also serve the locomotion as usual, without great expenditure on apparatus, even in water depths of interest to the snorkel diver that previously could not be reached for a long time without pressure bottles, can dive for any length of time, ultimately limited only by other physiological opportunities (fatigue, hypothermia).
