Definitions

  • the invention relates to a method of manufacturing a gliding machine on snow or ice and the machine obtained by the method.
  • skis In the field of alpine skiing, skis are used which have composite structures formed by the superposition of layers on either side of a core.
  • the lower layer of this structure is constituted by lower elements and is formed by the sliding sole which is laterally bordered by the edges, and the upper layer of this structure is called the upper subassembly and may comprise different layers, one of which outer layer of decor, possibly one or more reinforcements.
  • manufacturing consists of preparing the constituents of the gliding board, with the exception of the core, and then placing the latter in a mold before pouring a liquid or foamy material, the expansion and hardening lead to form the nucleus.
  • gliding machines having a gliding board, on the upper surface of which is fixed an interface device, which serves, inter alia, to facilitate the attachment of a device for retaining a shoe , that is to say for example, a stop and a heel. It is known to fix these interface devices independently of the manufacture of the gliding board. That is to say, for example, that the gliding board is made up to the finish and then the screw interface device is attached thereto or by gluing.
  • the document DE 203 20 276 describes a ski that includes an interface device and which is obtained by the injection technology.
  • the interface device is attached to the ski only when the liquid or foamed material is expanded and hardens.
  • Such a method of manufacture poses many problems. Firstly, the introduction of the various constituent elements in the mold proves delicate insofar as, before the complete end of the cycle, that is to say the hardening of the core, none of the various constituent elements 'is fixed with respect to the other. This can lead to positioning inaccuracies, especially between the interface device and the upper subassembly. On the other hand, to ensure good grip of the interface device in the core, it is necessary to maximize the surface of the portions that will be embedded therein.
  • the material which constitutes the core is generally a foam which, although hardened, may be subject to a long-term settlement.
  • the compression leads to the creation of a relative game between the interface and the kernel.
  • Another disadvantage of this embodiment is its poor sealing. Indeed, during the injection the core material is poured into the mold in the liquid state and under some pressure and leakage are very likely at the openings in the upper subassembly for the passage of portions of the interface that will be immersed in the core.
  • the present invention aims to provide a method of manufacturing a gliding machine and a gliding machine obtained by this method that allows to overcome the limitations posed by the devices known in the prior art.
  • the invention aims to provide a method of manufacturing a gliding device by which the positioning of the constituent elements can be placed more simply and faster relative to each other in the mold before injection.
  • the invention also aims to provide a gliding device which comprises a gliding board and an interface device, which is integrated with the gliding board during the manufacture of said gliding board and for which a perennial catch of the interface device on the gliding board is guaranteed.
  • the second step comprises the preparation of a decorated top, possibly one or more reinforcements and a film placed on the lower surface of said upper subassembly.
  • the anchoring elements are pins projecting from the interface device and intended to pass through said upper subassembly. Said pins can be directly from the interface device or be independent with respect to the latter.
  • the object of the invention is also obtained by the provision of a gliding apparatus comprising a gliding board and an interface device for fixing the one or more retaining elements of a boot on said gliding apparatus and constituted by lower elements, an upper subassembly and a core filling the cavity formed between said lower elements and said upper subassembly characterized in that said interface device is fixed by means of anchoring on said subassembly superior.
  • the core is obtained by curing a liquid or foamy material and it comes into contact with said anchoring means.
  • the interface device is fixed on the upper subassembly, which is fixed over its entire area to the core of the gliding board.
  • the phenomenon of compaction of the core foam at the anchor elements in the core is completely removed.
  • the material of the core comes into contact with the anchoring elements, it is possible to avoid any risk of the interface device being detached in the case where the latter is fixed by screws.
  • the anchoring elements are directly derived from said anchoring device and are fixed to the upper subassembly by bouterollage.
  • Figure 1 shows an overview of a gliding apparatus 1 according to the invention. It comprises a gliding board 2 and an interface device 3, which serves to fix the two retaining elements that are the front stop 4 and the rear heel piece 5.
  • the interface device comprises a plurality of notches 7 serving to facilitate flexion.
  • a shoe 6 can be maintained between the two retaining elements and released depending on the forces that apply to the latter.
  • the manufacture of such a gliding apparatus comprises the following steps: the first step consists in the preparation of the lower elements.
  • the lower elements 8 comprise a sole, which is framed by edges.
  • the sole which includes the surface of the gliding machine that will be in contact with the snow, is made of a material that promotes sliding.
  • the edges are placed on each side of the sole and are usually made of metal.
  • the lower elements also include one or more reinforcements.
  • the second step consists in the preparation of an upper subassembly 9, which comprises a decorated top and optionally one or more reinforcements. Depending on the chosen materials, it may or may not be thermoformed.
  • the upper subassembly 9 also comprises a film 19. This film is placed on the lower surface of the upper subassembly 9, that is to say on the surface which will be in contact with the core.
  • This film 19 is made of a thermoplastic or heat-sealing material so that the areas of this film which are in contact with the material of the pin during the peeling operation, partially melt, thus ensuring a perfect seal.
  • the film 19 is preferably an ionomer resin film or EMAA (acidic methacrylic ethylene) or an EVA / PA heat-sealing film.
  • EMAA acidic methacrylic ethylene
  • the film 19 may be applied over the entire lower surface of the upper sub-assembly 9, or only on the central zone thereof, that is to say the one at which the interface device must be fixed. 3.
  • FIG. 2 shows, in partial perspective view, the upper subassembly 9 at the end of the second step.
  • the interface device 11 is shown in perspective in FIG. 3. It consists of a plate from which a plurality of pins 12 originate.
  • the third step consists in fixing the interface device on the upper subassembly 9.
  • This third step comprises several phases. During the first of these phases, the interface device 11 is placed on the upper subassembly so that the pins 12 fit into the holes 10.
  • FIG. 4 describes in cross section the upper subassembly on which the interface device 11 is placed.
  • FIG. 5 describes an alternative version of the first embodiment of the invention wherein the interface device 11 is not made of a one-piece part.
  • the interface device comprises a body 13 and a plurality of independent pins 12 '.
  • the body 13 may be made of a material different from that used for producing the pins 12 '.
  • a material different from that used for producing the pins 12 ' we can achieve the aluminum body, while the pins are made of a plastic material.
  • the plastic body of the PU (polyurethane), PA (polyamide), PE (polyethylene) or PP (polypropylene) type and the pions of a metallic material, or the pions and the body in plastic material.
  • the second phase of the third step of the first embodiment of the invention consists of the pegging of the anchoring elements that are the pins 12, 12 '.
  • FIG. 6 depicts, in cross-section, the upper subset to which the interface device 11 is attached at the end of the second phase of the third step. It can be seen that the material at the level of the pawns 12 has fluted to come against the upper subassembly 9 and stick to it.
  • the fourth step are placed in the mold 14, the lower elements 8 and the upper subassembly 9 which is integrally attached the interface device 3.
  • this step is simplified by the fact that it is no longer necessary to ensure the relative good positioning of the interface device relative to the upper subassembly.
  • a liquid material is poured into the cavity formed between the upper subassembly and the lower elements. It is a PU type material that will expand and then harden inside the mold to form a core between said lower elements and said upper subassembly.
