Definitions

  • the invention relates to a ski, namely a downhill ski and a cross-country ski according to the kind defined in the preamble of claim 1.
  • the invention has for its object to simplify this ski, to increase the ease of use for the driver and to improve the spring properties of the ski.
  • the spring is thus omitted, so that the ski is simpler than the known one.
  • the difference in the elasticity of the ski is caused solely by the material surrounding the first room and / or the shape of the first room.
  • the driver no longer has to work against the spring, which is very powerful, when adjusting the piston, so that he can make the adjustment more easily.
  • the spring properties of the ski material are better than those of a spring acting on the piston.
  • the invention does not exclude that a spring acts on the piston, which does not affect the spring properties of the ski, but other tasks fulfilled, for example the one to move the piston perfectly into its zero position.
  • the ski end 1 has a narrow space 2, which is possibly stiffened by means of ribs 3 with a certain elasticity.
  • the room 2 is filled with a liquid that is not freezing at low temperatures, for example an oil.
  • a compensating tank 4 which is connected to the room 2 via a line.
  • the liquid is also in the vessel 4.
  • a porous piston 6, which is adjustable in the vertical direction and can be actuated by the driver, sits above it.
  • the piston 6 is at a distance from the membrane 5: If the ski end 1 is moved upwards according to arrow 7, the volume of the space 2 is reduced and the liquid escapes into the vessel 4. The liquid level and thus the membrane rise. The end of the ski is soft.
  • the piston 6 If the piston 6 is pressed onto the membrane 5 and thus onto the liquid level (whereby the air between the piston 6 and membrane 5 can escape via the pores), the liquid can no longer escape upwards in the compensating vessel 4 when the ski end 1 moves .
  • the ski end 1 is hard.
  • the shape of the room 2 can influence the bending line of the ski.
  • the adjustment mechanism of the piston is expediently such that the variability of the elasticity of the conscious area is achieved by a small adjustment movement.
