Definitions

  • the invention relates to means for practicing cross-country skiing, more particularly intended for the technique known as "the skater's step”.
  • this technique in a known manner, consists in evolving by making diverge your skis from the direction of progression, progression proper being provided by the alternative exercise of impulses transverse by the skier on one of his skis.
  • this technique consists in ensuring the progression not by the exercise of a thrust in the longitudinal direction, but at the contrary by means of successive and alternating transverse supports. he It is therefore advisable to optimize the grip, that is to say the impulse, by making it as effective as possible, therefore ensuring when taking pulse, maximum energy transfer.
  • the ski In order to reduce the duration of this pulse, and to decrease it effort, so the ski must be able to tilt easily on its edge internal without causing too much energy loss by the skier, nor inherent resistance to friction of the ski on the internal edge by its progression in the tilted position.
  • This tilting of the ski on its edge Internal movement is accomplished by moving the knee inward. 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 formed by the knee, relative to the base of the sole, that is to say with respect to the sliding face of the ski sole. In other words, these two parameters can be summed up in the way following: the width of the ski sole and the distance between the base of this sole and the base of support of the skier's shoe on the ski, these two parameters being measured at the level of the ski skid.
  • this tilting of the ski by relation to the internal edge is analyzed as a rotational movement by relative to an axis formed by this edge, and the energy required to perform this tilting amounts to calculating the moment of the force at the origin of rotation relative to this axis of articulation.
  • the defining characteristics the value of this moment consist of the intensity of the force 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 in front be heard in its geometric sense.
  • a solution may consist in increasing this distance from the point of application.
  • the invention therefore aims to reduce the energy required to set up works this tilting around the internal edge, in order to be able allow this support, while maintaining a duration of acceptable tilting.
  • the invention therefore relates to a means for achieving the better compromise between the energy required for tilting and the duration of it.
  • these means comprising at least two skis each fitted with a binding allowing the front to be secured from the skier's shoe to the ski, said means having at the level of the thickest area 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 skate level over the distance between the sliding surface and the sole of the skis from the base of the boot to the surface upper of the skis or on the plate for fixing said boot to the ski is between 0.6 and 1.2.
  • the invention consists in increasing the height between the sole of the ski and the boot, and more precisely of the base support of the boot on the binding of the ski.
  • the fundamental characteristic means for a complete ski that is to say, provided with its binding if necessary, WHEREAS the defined report takes into account the support base of the shoe.
  • This support base is itself well defined, and corresponds to the sole surface of the shoe actually resting on the ski, or on the plate of the binding, or on any added element or integrated on or in the ski, during the impulse phase.
  • the known elevations in the ski area in no case have the same or similar purpose as that of cross-country skiing, since in particular, the principle of progression put in work is totally different.
  • the height defined above that is to say the distance between the sliding surface of the sole of the ski and the base support 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 binding of the boot to the ski, possibly with its own fixing plate or plate.
  • the shims thus added have a thickness comprised between 5 and 30 mm, and advantageously close to 10 mm.
  • this wedge is integrated into the internal structure of the ski.
  • said wedge is inclined in direction of the front end of the ski, the area at the heel constituting the highest point.
  • a layer of a visco-elastic element we interlayer between the cleat and the upper surface of the ski at the level of the skate, a layer of a visco-elastic element, in order to increase the comfort of the skier.
  • the wedge is integrated into the level of the mounting plate.
  • the height of the plate is between 10 and 30 mm.
  • FIG. 1 therefore schematically shows a cross-country ski represented in section longitudinal.
  • This ski (1) has, in known manner, two ends, respectively the heel (2) and the spatula (3), and also includes a gliding sole (4) extending over the entire length of the ski.
  • the skate area corresponding to a substantially central area is the thickest area of the ski.
  • This zone of the shoe (5) receives the fixing, allowing the front of the ski boot.
  • this area of the skate has an elevation (6) which, in this case, is integrated in the internal structure of the ski.
  • the upper face (7) of the ski does not present any discontinuity of nature, i.e. the layer upper, most often decorated, is continuous and envelops the outgrowth constituted by this elevation.
  • the thickness at the level of the pad reaches, taking into account this elevation (6), a height D of 45 mm, said height being measured from the sliding face of the sole (4) to the bearing face (6) of the boot, that is to say facing the level of which it is fixed on the binding and on which comes to rest the foot of the skier in the impulse phase.
  • the ski itself is a traditional cross-country ski, the thickness d of which at the level of the skate is typically 35 mm and its width L of 45 mm.
  • This ski receives a wedge (8) attached to the upper face (7) of the ski by any means, in particular by bonding.
  • a sheet of visco-elastic material (9) intended to dampen vibrations, and more generally, to increase the comfort of use of the skier.
  • 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) allows the knee to be moved 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) is higher at the heel (10), that is to say at the point of support of the skier's heel, and therefore has a certain downward inclination towards the front of the ski. In this way, we induce the displacement of the center of gravity of the skier upstream, typically in front of the binding, favoring the practice of the so-called "skater's step” technique.
  • the wedge (8) provided with the fixing, can be joined reversibly to the surface upper of the ski, so that it is possible to select the type of cleat desired, especially in terms of thickness, profile, or rigidity, in depending on the type of snow encountered.
  • the increase in height separating the gliding sole from the base support of the skier's shoe can be obtained by providing the fixing of a relatively thick plate, suitable for replace the role of the shim (8), or achieve this result in combination with a thinner shim.
  • the skis according to the invention therefore favor pivoting relative to at their internal edge, reducing the time required for this pivoting or tilting, and hence, optimizing the setting phase impulse, fundamental during progression according to the so-called technique of the skater's step.
