Definitions

  • the present invention relates to a shaped ski, of non-rectangular section.
  • skis comprising a filling core made of synthetic foam, for example polyurethane, which has excellent properties of stability over time, and is of low weight.
  • the documents FR 2 611 518, FR 2 615 404 and EP 0 394 835 relate to shaped skis, comprising a shell forming the inclined lateral faces of the ski, a core of rectangular section, reinforcing elements in contact with the inclined walls, with space management between the inclined walls and the core, which is filled with viscoelastic elements having a vibration damping power.
  • the longitudinal reinforcing elements provide excellent support for the edge, as well as the transmission of the forces received by each edge towards the upper face of the ski provided with the binding.
  • Each reinforcement element can extend practically over the entire height of the ski and serve as a support, on the one hand, for an edge and, on the other hand, for the upper face of the ski, or on the contrary only extend over part of the height of the ski, and be associated with a reinforcing element in contact with the upper wall of the hull, and taking up the forces transmitted from the edge.
  • This force recovery element can be constituted for example by a fabric impregnated with resin.
  • Each reinforcement element can be produced in several parts butted in the longitudinal direction and produced in materials having different characteristics, or in several parts juxtaposed and produced in different materials.
  • the reinforcing elements are rigid, the end zones of these same elements being able to be more flexible and produced. for example in a viscoelastic material.
  • each reinforcing element can be made of a solid material, such as wood, a synthetic material, or else be made from fabric impregnated with resin and folded back on itself, or else in a multimaterial complex, such as Zicral-ABS, Zicral being a registered trademark for an aluminum alloy and ABS being acrylonitrile-butadiene-styrene.
  • the reinforcing elements extend over the entire active length of the ski, that is to say substantially between the front and rear contact zones of the ski on snow, while the shell completely covers the reinforcing elements.
  • a seal of viscoelastic material is interposed locally in the end zones of the ski between the hull and the upper part of each reinforcing element, or between the hull and the edges.
  • Such a ski can be obtained with prior production of the core and assembly in the mold of the shell reinforcement elements, or else by pre-assembly of the reinforcement elements with the shell before in situ molding of the core. It is also possible to extrude the reinforcing elements with the shell, before molding the core.
  • the ski shown in FIGS. 1 to 3 is a shaped ski, of non-rectangular section, comprising a filling core 2, for example made of polyurethane foam, a shell 3 forming the upper face 4 of the ski and the two lateral faces 5 thereof, longitudinal metal edges 6, and a sliding sole 7.
  • a filling core 2 for example made of polyurethane foam
  • a shell 3 forming the upper face 4 of the ski and the two lateral faces 5 thereof, longitudinal metal edges 6, and a sliding sole 7.
  • this ski comprises two longitudinal reinforcing elements 8, extending at least in the skid zone of the ski, arranged on either side of the core 2, between the latter and the inclined faces 5 of the shell 3.
  • Each reinforcing element 8 has a lower face serving to support an edge 6, so as to provide it with effective support.
  • each reinforcing element 8 extends practically over the entire height of the ski and serves to support the upper face 4 of the hull.
  • each reinforcing element has a face, intended to bear against the core, which is perpendicular to the plane of the sole.
  • FIG. 3 shows the location between the edges of the shell 3 and the base of the reinforcing elements and the edges 6, in the end zones, of a layer of viscoelastic material 9.
  • FIG. 4 represents a variant of the ski of FIGS. 1 to 3, in which each reinforcement element 18 extends over only part of the height of the ski, and is integral with a reinforcement element 19 constituted for example by a fabric impregnated with resin, which is itself in contact with the upper face 14 of the shell, and which is intended to transmit to the latter the forces to which the edges 16 are subjected.
  • FIG. 5 represents another embodiment of this ski, in which each reinforcing element 28 has a face intended to bear against the core 22, which is inclined relative to the perpendicular to the plane of the sole.
  • FIG. 6 represents a ski, without the shell, in top view, in which each reinforcing element, designated by the general reference 38, has a constant base width over its entire length, the core 32 having for its part a width variable to take account of the ski's dimension lines.
  • each reinforcing element is constituted by a multimaterial complex, comprising at least two different materials, for example a central layer of Zicral 38a and two lateral layers of ABS 38b.
  • FIG. 7 shows another embodiment, in which each reinforcing element 48 has a variable base width along the ski over its entire length, while the core 42 has, for its part, a constant width along the ski.
  • each reinforcing element comprises a central part 48a extending at least in the ski skid zone, made of a rigid material, and two end zones respectively before 48b and rear 48c, which are butted longitudinally to the area 48a, and which are made of a material having different characteristics, for example in a viscoelastic material.
  • Such a combination is advantageous insofar as it is necessary to have excellent support at the level of the pad, which is achieved by the rigid element 48a, and that it is advantageous to obtain good damping at the level of the ends, which is obtained thanks to the viscoelastic elements 48b and 48c.
  • the invention brings a great improvement to the existing technique by providing a shaped ski, of non-rectangular section, having the presentation qualities of skis with a hull, while having the technical characteristics of behavior of the traditional skis.
  • reinforcing elements could be monolithic, or that the reinforcing elements could only extend in the central part of the ski, or that some of the characteristics, described with reference to an embodiment, could be combined with features described with reference to another embodiment without departing from the scope of the invention.
