Definitions

  • the present invention relates to a ski comprising, in cross section, a central core, load-bearing elements arranged above and below this core, a lower sliding sole, an upper decorative layer, two edges laterally bordering the sole. and a portion of which extends above a marginal portion of its upper face and two edge elements arranged laterally on either side of the core.
  • the structure of the skis generally comprises a solid or hollow core and load-bearing elements arranged above and below this core, which can be produced in one or two layers, for example of a fiberglass fabric impregnated with resin. epoxy possibly combined with a metal blade made of aluminum or aluminum alloy of the Zicral 7075 type.
  • US-A-4,093,268 relates to a ski in which a glass fiber reinforcement is arranged between an edge element and the core and extends vertically between a lower edge and an upper edge.
  • a similar structure is illustrated in US-A-3,967,992.
  • US-A-4,455,037 describes a structure in which a metal reinforcing blade is interposed between the edge elements forming the side faces of the ski and a wooden core, these reinforcing blades extending between a supporting layer lower and upper edges.
  • the upper surface of the ski which also constitutes the decorative part, is particularly exposed to external aggressions liable to damage it by giving the ski visible wear which degrades it, even if its mechanical properties are not affected. It is for this reason that a good number of skis have not only lower edges, intended to improve the grip of the ski on snow or ice, but also upper edges intended to protect the decorative part, in particular during a crossing. Skis. In terms of manufacturing the ski, these upper edges increase the number of parts to be assembled and complicate the structure of the ski since, like the lower edges, they must be anchored in the ski.
  • the object of the present invention is to provide a more rational solution than hitherto for the protection of the upper face of the ski, while having recourse to a traditional manufacturing method by assembling elements in strips around a core. , either dry or wet.
  • the present invention relates to a ski as defined by claim 1.
  • the structure of the ski according to the invention has several advantages. It makes it possible in particular to solve, in a simple and effective manner, the problem of protecting the upper face of the ski.
  • This structure also provides effective protection against the sinking of the lower edges and advantageously makes it possible to produce the lower carrying element with a single layer, the thickness of which is completely independent of the anchoring part of the lower edges by making match the thickness of the edge elements and the width of the edge anchoring portions. The number of elements is thus reduced and their assembly for bonding is simplified.
  • the embodiment illustrated in FIG. 1 has a core 1 which can be made of a rigid foam of a polymer such as polyurethane for example.
  • Two load-bearing layers 3 and 4 are arranged respectively above and below the core 1. These two load-bearing layers are made of materials with high elastic modulus, for example by a laminate of glass fibers, carbon or Kevlar , by an aluminum alloy type 7075 etc ... or by a combination of these materials.
  • a reinforcing plate 2 can be placed intended to ensure good hold of the fixing screws.
  • a sliding sole 6 extends below the supporting layer 4. This sole 6 is bordered laterally by edges 7 and 8, portions 7a respectively 8a of which extend above the sole 6 as close as possible to the respective edges of the supporting layer 4.
  • Each edge 7 and 8 is adjacent to an edge element 9 respectively 10, the thickness of which corresponds to the width of the portions 7a, 8a of the edges 7 and 8 extending above the sole 6.
  • the spaces 11 formed between the edge of the carrier layers 3 and 4, the edges of the metal strip 2 and the internal faces of the edge elements 9 and 10 are intended to receive the excess glue which is used for bonding the various shapes. - skiing health.
  • Each edge element 9 and 10 consists of a laminate comprising three layers, namely an intermediate reinforcing strip 12 and two layers of polymer or phenolic laminate 13 and 14 arranged on either side of the reinforcing strip 12.
  • the reinforcing strip 12 is made of aluminum or of an aluminum alloy of the Zicral 7075 type and the layers of polymer are bonded to the faces of this strip. The symmetry of the room avoids the deformation during hot bonding.
  • Other reinforcing layers can be envisaged such as a laminate similar to that used to form the supporting layers 3 and 4 in glass fiber fabric embedded in epoxy resin for example.
  • the upper face of the ski formed from the external face of the carrier layer 3 and the upper edges of the edge elements 9 and 10 is covered with a protective layer 15 constituting the decorative face of the ski. Two marginal portions of this layer 15 are then eliminated by chamfers 16 and 17 which reveal the upper edges of the reinforcing blades 12 which therefore play the role of upper edges.
  • the reinforcing blades 12 play several roles, namely preventing a sinking of these edges 7 and 8 during impacts, providing protection for the upper edges of the ski while giving the ski a reinforcement in lateral bending and in torsion.
  • the laminated edge elements 9 and 10 in which the reinforcing blades are sandwiched preferably have a thickness equal to the width of the portions 7a and 8a of the edges 7 and 8. Since the protection against sinking is provided by the reinforcing blades 12, it becomes unnecessary for the carrier layer 4 to extend above the edges.
  • the described ski structure lends itself particularly well to dry manufacturing, that is to say by bonding layers of polymerized materials precut to the desired dimensions and assembled together.
  • this structure is not limited to this manufacturing method, but promotes it by the simplifications it brings.
  • the thickness of the laminate forming the edge elements 9 and 10 may be different from the width of the portions 7a and 7b of the edges 7 and 8.
  • this variant is identical to the previous embodiment and the same elements are designated by the same references. For these reasons, this variant will not be described again.
  • the variant illustrated in FIG. 3a and which obviously applies to the skis illustrated in FIGS. 1 and 2 differs from these in that the upper edge of the edge element 9 'extends at a level higher than that of the layer of protection 15 'constituting the decorative face of the ski which is then narrower.
  • This variant aims to provide better protection of the upper face of the ski by the reinforcing blade 12 '.
  • the other elements of this variant are identical to those described with reference to FIG. 1 and will therefore not be described here again.
  • the variant of fig. 3b shows a song element 10 'which reaches flush with the decorative surface 15'.
  • this edge element comprises two reinforcing blades 12 "and 12" 'parallel and separated by a layer of intermediate polymer 18.
