Definitions

  • the invention relates to a surfboard.
  • Surfboards or boards are known in many variants, for example as surf surfboards or as windsurf boards with a sail. They are all agile and allow elegant gliding on the water.
  • the object of the invention is now to make the advantages of light, elegant gliding possible regardless of fire or wind on any body of water, the surfboard also being secured against tipping over at slow speeds. Another object is to provide a corresponding conversion unit for a conventional surf or windsurf board, which allows the surfboard to be converted back to windsurfing operation in a simple manner at any time.
  • the proposed surfboard creates a watercraft equivalent to two-wheelers on the road, which is to be moved in particular by muscle power ("Velo surfboard”).

  • the force from these mechanical drives is transmitted to the hydraulic propulsion devices via chain, belt, rope or gear drives, preferably via low-friction gear systems, in particular planetary gear, bevel gear or the like.
  • the gear drives with light and smooth-running plastic gears are preferred because of the low manufacturing costs.
  • hydraulic propulsion devices are propeller, screw, paddle wheel; Piston or centrifugal pump for generating a liquid pressure in the liquid drive medium with a downstream water jet nozzle; fin-like flaps or the like conceivable.
  • the seesaw movement of this seesaw drive should be transferable to raft-like or flap-like propulsion devices by mechanical linkages.
  • the fin-like propulsion devices should increase in elasticity towards their free ends, which can be achieved by reducing the cross-section or by increasing the elasticity of the material used towards the free end or also by reducing the number and / or the cross-section of these drive fins in the longitudinal direction. stiffening materials is accessible.

  • the steering of the surfboard takes place in that the handlebar or steering wheel-like holding device can be rotated about its longitudinal axis and is in direct or step-down connection with a rudder blade or a pivotable propeller carrier.
  • the steering can also be done by pivoting the other hydraulic propulsion devices.
