Definitions

  • the invention relates to means for practicing cross-country skiing, more particularly intended for the technique known as "skater's step”.
  • this technique consists in ensuring progression not by the exercise of a thrust in the longitudinal direction, but on the contrary by means of successive and alternating transverse supports. It is therefore advisable to optimize the taking of support, that is to say the impulse, by making it as efficient as possible, therefore by ensuring during this taking of impulse, the maximum transfer of energy.
  • the ski In order to reduce the duration of this momentum, and to decrease the effort, it is therefore necessary that the ski can easily tilt on its internal edge without generating too great a loss of energy by the skier, nor of resistance inherent in the friction of the ski on the internal edge by its progression in the tilted position.
  • This tilting of the ski on its internal edge is effected by displacement of the knee inwards.
  • It is conditioned by two essential parameters related to skiing, namely the width of the ski and the distance from the point of application of the tilting force, typically constituted by the knee, relative to the base of the sole, ie in relation to the sliding face of the ski sole.
  • these two parameters can be summarized as follows: the width of the sole of the ski and the distance between the base of this sole and the base of support of the skier's boot on the ski, these two parameters being measured at the level of the ski skid.
  • this tilting of the ski relative to the internal edge is analyzed as a rotational movement relative to an axis formed by this edge, and the energy required to effect this tilting amounts to calculating the moment of the force causing the rotation relative to this axis of articulation.
  • the characteristics determining the value of this moment are constituted by the intensity of the force exerted on the one hand, and by the distance from the point of application of this force relative to the axis of articulation on the other hand, the term distance to be understood in its geometric sense. In fact, as soon as one wishes to reduce the intensity of the force to be exerted to tilt the ski, one solution may consist in increasing this distance from the point of application.
  • the invention therefore aims to reduce the energy required to implement this tilting around the internal edge, in order to be able to allow this support, while maintaining an acceptable tilting time.
  • the invention therefore relates to a means making it possible to reach the best compromise between the energy required for tilting and the duration thereof.
  • these means comprising at least two skis each provided with a binding allowing the front of the boot of the skier to be secured to skiing, said means means having at the level of the thickest zone of the skis, and typically at the level of the skate, a thickness such that the ratio of the width of the sole of the skis to the level of the skid over the distance separating the sliding surface from the sole skis of the base of support of the boot on the upper surface of the skis or on the plate for fixing said boot to the ski is between 0.6 and 1.2.
  • the height defined above that is to say the distance separating the sliding surface of the ski sole from the support base of the boot on the upper surface of the ski, or on the plate of the binding or on any raised element attached to the ski, is at least equal to 40 mm and at most equal to 60 mm.
  • this height can be obtained by fitting a shim added to the upper surface of the ski, on which the binding is placed allowing the boot to be joined to the ski, optionally provided with its own plate or fixing plate.
  • the shims thus added have a thickness of between 5 and 30 mm, and advantageously close to 10 mm.
  • this wedge is integrated into the internal structure of the ski.
  • a layer of a visco-elastic element is inserted between the added shim and the upper surface of the ski at the level of the skate, in order to increase the comfort of the skier.
  • the shim is integrated at the level of the fixing plate.
  • the height of the plate is between 10 and 30 mm.
  • FIG. 3 is a diagrammatic representation in cross section of the ski along line III - III of FIG. 2.
  • Figure 4 is another embodiment of the invention.
  • FIG. 1 therefore schematically shows a cross-country ski shown in longitudinal section.
  • This ski (1) comprises in a known manner two ends, respectively the heel (2) and the tip (3), and also comprises a gliding sole (4) extending over the entire length of the ski.
  • FIG 3 a cross section of the ski of Figure 2, made at the level of the skate.
  • the reference G 1 schematically represents the knee of the user on a traditional ski, and it can be observed in fact that the positioning of the wedge (8) makes it possible to move the knee away in a position G 2 from the gliding sole (4), and thereby decreasing the angle ⁇ 2 ⁇ 1 defined by the intersection of the straight line joining points G 2 and G 1 of one of the edges (11, 12) of the sole respectively sliding of the ski, and of the plane integrating the side edges (13, 14) of said ski.
  • the wedge (8), provided with the binding can be joined reversibly to the upper surface of the ski, so that it is possible to select the type of wedge desired, in particular in terms thickness, profile, or stiffness, depending on the type of snow encountered.
  • the increase in the height separating the gliding sole from the support base of the skier's boot can be obtained by providing the attachment with a thick plate. relatively large, suitable for replacing the role of the shim (8), or for achieving this result in combination with a thinner shim.
  • the skis according to the invention therefore favor pivoting with respect to their internal edge, reducing the time necessary for this pivoting or tilting, and therefore making it possible to optimize the impulse phase, which is fundamental during progression according to the technique. known as the skater's step.
