Definitions

  • the present invention relates to a process for the preparation of Snow board edges, such as a ski, a monoski, or a snowboard example. Being a ski, this ski can be a snow ski generally of the Alpine kind, but it can also be a ski touring or even a cross-country ski. The invention also relates to edges that can be produced by this method.
  • edges are often, as described in document EP-A-0 332 503 and represented in FIG. 1 attached, provided with mechanical anchoring fins 1 in the ski. experience indeed shows that the edges can be torn off when the ski hits very violently a stone or a rock on the track. These fins, being drowned in the synthetic material during the manufacturing phase, provide a appreciable mechanical anchoring effect of the edges in the internal structure of the ski.
  • the short transverse slits determining the fins make it easier to bend the edges to follow the shape of the plank slips.
  • depressions are not tolerable because the sole of a board of gliding on snow must be smooth to allow a good gliding, so that one is forced to engage in multiple manual operations out of the mold sanding the sole to remove them, which penalizes very heavily the cost price of each ski.
  • these sandings lead to a reduction in the thickness of the gliding sole, and therefore faster wear of the board.
  • Another solution to keep the elements intended to form the edges of the gliding board consists of raising (or to twist) certain fins which thus occupy a stop function to maintain certain elements in place. This method is not very industrial and therefore expensive.
  • EP-A-0 249 894 shows ski edges provided with cavities intended to be filled with glue during assembly of the structure in order to promote attachment edge mechanics inside the structure. This filling operation appears delicate.
  • the invention aims to remedy these drawbacks.
  • edges for snow gliding boards these edges being provided with fins or cavities, according to which we fill, at least partially and before the incorporation of these edges into the structure of the board, the spaces left free between these fins or by these cavities by a synthetic material capable of solidify without shrinking, this filling being done so that the surface lower edge, that is to say that intended to be in contact with the sole, is very smooth and therefore free from depressions.
  • the invention therefore makes it possible to eliminate the hollows appearing along metal edges after molding on the sole of the gliding boards, everything retaining the ability to bend the edges and without penalizing their hooking mechanical inside the structure.
  • Another characteristic of the invention is to replace the strip of elastic covering generally arranged between the edge and the elements higher.
  • the invention therefore makes it possible, at the same time as filling the inter-fin cavities, to deposit a thin layer of material if necessary elastic or viscoelastic on the upper surface of the edges.
  • the aforementioned spaces or cavities 2, left free between the fins 1, are, before the edges 5 are placed in the ski manufacturing mold, filled with a synthetic material 6, such as the A.B.S. (Acrylonitril Butadiene Styrene) for example.
  • a synthetic material 6 such as the A.B.S. (Acrylonitril Butadiene Styrene) for example.
  • Figure 4 shows the structure of a traditional ski, equipped with edges 5 according to the invention.
  • This ski comprises a sliding sole 7, bordered by said edges 5, a reinforcement fabric 8 which covers the sole 7 as well as the edges side 5, a core 9, side edges 10, and an upper layer of protection and decoration 11.
  • the sole 7 and the reinforcement fabric 8 are previously glued.
  • the material 6 for filling the fins 1 is, after the total baking operation in the mold, firmly secured by bonding to the two layers 7 and 8 which trap it: this synthetic layer of filling 6 with better bondability than the steel constituting the edge metallic, keeps the anchoring qualities that must have fins.
  • the material of filling 6 can also be added above the edges 5 so as also completely cover these with a layer 12 of this synthetic material.
  • FIG. 7 An interesting variant of the invention according to one of FIGS. 3.5, or 6, is illustrated in FIG. 7. It consists in bringing back this synthetic material 6 by making it further define, on the upper face of the edge 5, a rib longitudinal 14 which can be either a continuous rib, and therefore extending from a end to end of the edge, advantageously, as shown in Figure 8, a discontinuous rib and therefore made up of an alignment of elongated studs 14A
  • Figure 9 shows a portion of a ski similar to that according to Figure 4, but provided with edges 5 according to FIG. 7, therefore with a continuous rib 14 or discontinuous 14A.
  • edge is well held in position by the rib 14 or 14A, which is an advantageous advantage for the production of an injected ski In Located according to the structure presented.
  • Figure 10 shows another interesting application of the edges according to FIG. 8, that is to say filled with discontinuous studs 14A, to an In Situ injected ski, comprising a core 15 of injected Polyurethane, a rigid lower internal reinforcement 8, and a plastic shell 16 lined internally by an upper reinforcement 17.
  • the studs 14A also serve to support the lower reinforcement 8 during the core 15 injection operation, which is advantageous because currently, special bosses must be provided in the reinforcement 8 to keep it at a distance above the sole 7 during the operation injection to allow the passage of the foaming product between the sole and this reinforcement, the foaming product becoming an intermediate bonding.
  • Figures 11 and 12 similar to Figures 7 and 8, show another variant according to which the synthetic material 6 which fills the intervals between fins 1 is provided, on its upper face 19 only, with blind 18 depressions, which increases the anchoring function which must be generated by fins 1. More generally, it is possible to not fill the space between the fins 1 with synthetic material 6 only incompletely, provided that the lower surface 20 of this filling 6 is very smooth and therefore free of depressions capable of generating the faults 3 mentioned previously with reference to FIG. 2.
  • the preparation of the edge according to the invention is carried out by conventional means of injection into a mold shaped for this purpose, according to the example shown in Figure 13.
  • a mold 25 is used which, with its cover 26 has a shape suitable for the production by injection of two edges 5 according to Figure 3 for example.
  • the two metal edges 5 are placed in the mold 25.
  • the cover 26 is then put in place, then the components of the synthetic material are injected hot into the injection orifice 27.
  • the synthetic filling material 6, and possibly covering 12, 13, 14, could be another matter thermoplastic, chosen from styrenics, polyamides, polyethers block amides, thermoplastic rubbers, softened PVC, etc.
  • This filling material 6 could also be chosen from among the thermosets: Polyurethane casting, Epoxy, rubber, etc.
  • the part added 6 could also be surmounted by various other continuous reliefs or discontinuous, made by molding, and therefore in one piece, with this part of filling 6.
  • a synthetic layer 12 which covers the upper face of the edge 5
  • this layer 12 of thickness which varies along the ski.
  • this thickness is then minimal at the level of the skate area, and it gradually grows on both sides of this area, towards the front ends and rear of the ski, which favors the precision of the turns.
  • this thickness is maximum in the skate area, and it decreases gradually from on either side of this area, towards the two ends of the ski.
  • this upper layer 12 is advantageously between 0.1 and 4 millimeters.
  • the fins 1 and the spaces 2 left between them could be replaced by cavities made in the edges 5, these cavities being either through or blind and therefore not through.
