Definitions

  • the present invention relates to a water ski according to the preamble of claim 1.
  • water skiing is a device that consists of a board or two skis that are towed at high speed by a motor boat. If, on the other hand, the "surfing" sport is practiced, a kind of wave rider is used, which also consists of a board that is held on the wave crest by cheap crash waves. In other cases, the board itself can be provided with a sail for its movement on the water.
  • the object of the present invention is to make the athlete completely independent of any force, be it by towing or by thrust, by proposing a water ski with such a structure that the movements on the water are due to their own strength of an athlete.
  • one-sided holding devices are provided on the sliding surface of a skid of the water ski, which inhibit the sliding movement of the ski on the water in the direction opposite to the direction of travel, the athlete is able to move with steps which can be carried out similarly to cross-country skiing.
  • Claim 2 describes a preferred embodiment of the water ski according to the invention.
  • the bellows-shaped caps on the sliding surface close, whereby the sliding movement is no longer hindered, whereas, on the other hand, they are filled with water by the action of the water as soon as the ski tends to slide in the backward direction: to take the step with the other ski.
  • Claim 3 describes a solution for beginners who may find it difficult to hold the skis together in parallel.
  • a water ski consists of a skid 1 which has a curved tip 2 at the front.
  • the runner is provided in the area of its surface with a foot holder 3, which is intended to receive one of the user's feet.
  • the rear part of the runner 1 is provided with a directional fin 5 which is immersed in water and which aligns the ski in the direction of travel with simultaneous stabilization of the runner 1 with respect to its longitudinal axis.
  • the runner 1 has a number of bellows-shaped caps 6 on its lower sliding surface, which are arranged along two longitudinal rows.
  • each bellows-like cap 6 has a substantially pyramid-shaped configuration with an apex 7 which is directed in the direction of the curved tip 2 and with an open base 8 which is directed in the opposite direction or in the direction of travel the runner 1 is directed in the opposite direction.
  • One of the triangular walls of each cap 6 is stably attached to or inserted into the sliding surface of the runner 1.
  • each cap can be drawn into the inside of the pyramid in order to converge in a bending line 10 which extends from the apex 7 to the base of each side wall 9:
  • the wall 11 of the pyramid opposite the sliding surface of the runner 1 can be separated from one completely open position of the runner 6, as is shown essentially in FIGS. 4 and 5, are brought into a closed position in order to nestle like a bellows on the surface of the wall connected to the sliding surface.
  • FIG. 6 shows a second embodiment of the water ski according to the invention, in which the runners as described above are used, the same parts being designated with the same reference numbers.
  • the two runners are coupled to one another by means of parallel links 12 and 13, each of the links at one end by a respective hinge 14 on one side of one of the runners 1 and at its other end by a respective hinge 15 at the opposite side of the other runner 1 is articulated.
  • the two runners 1 together with the links 12 and 13 form an articulated parallelogram.
  • the handlebars 12 and 13 can be made telescopic as indicated at 26.
  • This solution is particularly useful for beginners to avoid losing control when holding both runners together, i.e. that one of the runners "escapes", causing a fall into the water.
  • FIG. 7 shows a third embodiment in which a swimming board 25 is provided.
  • Two parallel longitudinal windows 16 and 17 are excluded from this.
  • each window 16 and 17, respectively has on its long side, i.e. in the forg movement direction, a guide 18 and 19 respectively.
  • One of the longitudinal edges of a runner 1 of a construction as described above is slidably received in each guide 18 or 19. So both runners 1 can slide independently of each other in the board 15, their parallelism being determined.
  • This solution can be described as a single ski with independent operation of the runners 1.
  • a ski pole 20 which has at its end an umbrella 21 which is in a stable opening position as soon as the water push acts on it in such a way that a support is created on the water for the user who is on the Water moves with the ski according to the invention.
  • the Holding means can also be designed differently without leaving the scope of the present invention:
  • the sliding surface 11 (FIG. 4) of a bellows-like cap could be replaced by a flap 26 which is hinged to a fastening plate 28 by means of a hinge 27, which in turn is attached to the lower surface of the runner 1 with a hinge oriented perpendicular to the longitudinal axis of the runner 1 27 are attached.
  • Each flap 26 has lateral wings 29 lying in the longitudinal direction of the runner 1, which engage in corresponding grooves 30 recessed from the runner 1 in the lower surface. The wings 29 are extended to above the plate 28, the extensions 31 in cooperation with the bottom of the grooves 30 forming the end stop for the greatest possible pivoting or opening of the flaps 26.
