Definitions

  • the invention relates to a board for sliding on a wet surface such as snow, ice or water and the manufacturing process for this board.
  • the invention relates to the method of manufacturing a ski intended for practice downhill skiing.
  • the invention also relates to a set for skiing on a wet surface such as water, snow or ice.
  • a ski in a known manner, comprises a central wooden core or foam, with a layer of reinforcing layers on top and bottom fibers impregnated with resin, metal or other.
  • the reinforcing and decorative layers placed on the above the core descend along the sides of the ski to join the edges and form thus a shell.
  • One of the functions of the lower and upper reinforcement layers is to isolate the central core of external humidity. This is important especially when the nucleus is in wood, or a material that retains moisture.
  • patent application EP 1 000 641 describes a interface device comprising two support plates for the retaining elements which are assembled to the ski by connecting pins transversely crossing the structure of the ski. At during the practice of skiing, the ski and the plates can pivot relative to each other around one and / or the other of the axes over a limited amplitude.
  • An object of the invention is to provide an improved gliding board which has better protection of the core against water penetration.
  • the gliding board includes a central core made of a material sensitive to humidity in particular in wood covered on the top and the bottom with layers of sole and reinforcement and at least one hole passing through a reinforcing layer and penetrating into the core. She is characterized in that at the level of the bore, the core immediately comprises under the reinforcing layer at least one cleat housed in a groove in the core.
  • the method of manufacturing the gliding board comprising a central core covered on the underside and the upper with sole and reinforcement layers is characterized by the it includes the steps of machining in a rough blank of the core at least one groove of defined section, of positioning in the groove of a cleat which fills the groove, joining the cleat to the rest of the core blank, machining the core blank thus obtained to give it the desired thickness and width curve.
  • the cleat isolates the rest of the core from any moisture that could penetrate at the level of the hole made.
  • FIG. 1 represents a ski assembly comprising a finished ski produced according to a mode nonlimiting implementation of the invention.
  • FIG. 2 illustrates the starting step of the method according to the invention applied to the manufacture of the ski of FIG. 1.
  • Figure 3 shows schematically the result of the first machining operation.
  • Figure 4 relates to the next step.
  • FIG. 5 illustrates the final phase of shaping the core.
  • Figure 6 shows schematically the next step in manufacturing the ski.
  • Figure 7 shows a side view of the finished ski.
  • Figure 8 is a cross-sectional view of the ski of Figure 7 at the drilling back.
  • FIG. 1 shows by way of illustration of the invention a ski assembly as it is described in patent application EP 1 000 641.
  • This set includes a ski 1 surmounted in its central area of two rear and front retaining elements 2 and 3. Elements 2 and 3 are supported by plates 4 and 5 which are connected to the ski by connecting pins transverse 6 and 7.
  • the axes 6 and 7 pass through the structure of the ski.
  • the central area of the ski has two bumps 8 and 9 which increase locally and gradually its thickness.
  • the blank 10 initially appears as an elongated beam of section rectangular. It is here formed for example of strips of wood of different species vertically oriented which are glued together. For example, the blank 10 is produced at from boards which are cut to the desired length and width. Other modes obtaining the draft may also be suitable.
  • the blank is machined to make two transverse grooves 12 and 13.
  • the grooves are located in the areas of the core which will be crossed later by axes 6 and 7, once the ski is finished, that is to say which will be located later in the central ski area.
  • the grooves 12 and 13 open onto the faces lateral and to the upper face of the blank.
  • Their cross section is of any shape appropriate.
  • Figure 3 shows in a nonlimiting manner a dovetail section. The sections may be different.
  • the cleats 14 and 15 are provided to be housed in the grooves 12 and 13.
  • the cleats are made of a material which is insensitive to humidity, in particular a material plastic such as ABS possibly loaded with fiber fibers.
  • the cleats 14 and 15 are provided to completely fill the grooves 12 and 13 in projecting relative to each of these surfaces as shown in Figure 4 or flush with the upper surface and the lateral surfaces of the blank 10.
  • the battens have in their lower part at least one section which is adjusted to the section of the grooves 12 and 13, and they preferably have a length equal to or greater than the length of the grooves 12 and 13. At the very least, the length of the cleats is greater than the width of the finished core, in this area of the ski.
  • the section of the cleats is chosen so as to subsequently fill them with holes in the lengthwise to a diameter equal to the diameter of the connecting pins 6 and 7 and the inserts which surround them if necessary.
  • a cleat of trapezoidal section whose large base measures 18 mm, the small one 14 mm and the height 11 mm. This cleat is designed to be drilled right through with a 7 mm diameter hole.
  • the cleats are bonded to the rest of the core by any suitable means, by example using a solvent. This prevents them from moving during the handling of the ski, and this facilitates subsequent machining of the core.
  • the core blank 10 is machined at the curve desired thickness and width.
  • the cleats 14 and 15 are machined on top and sides with the rest of the core, so their side surfaces and their upper surface is flush with the external surfaces of the rest of the nucleus. There exists a continuity of external surface between the wooden part of the core and the cleats.
  • this operation reduces the length of the cleat to the width of the ski whatever this width. That is to say, we can use the same model of cleat for make skis of different width.
  • the machining operation creates lateral recesses 20, 21, 22, 23 of the core at each of the ends of the grooves and cleats. These recesses are provided to provide housing for the lateral wings of the plates 4 and 5 once the ski is finished.
  • Figure 6 shows schematically the next step in manufacturing the ski.
  • Core 10 with its cleats 14 and 15 is placed in a heating mold between two series of layers, layer of sole 25 with its lateral edges 26, 27, and a lower reinforcement layer 28 for the below, upper reinforcement layer 29 and decoration layer 30 for the top. These different layers cover the core.
  • the upper reinforcing layer and the decoration layer descend along the flanks of the core to form a shell.
  • fiber reinforcement layers coated with epoxy resin Other construction methods may be suitable.
  • the method of construction of the ski is not limiting, and many variations exist depending on the structure of the ski, for example depending on whether the ski has or not metallic reinforcements, intermediate glue films. Skiing can be done according to various known manufacturing techniques, in particular as regards the shape of the mold, the temperature and pressure curves used, etc.
  • the reinforcing layers adhere completely to the outer wall of the core, in particular thanks to the resin which creeps under the effect of pressure in all available spaces or interstices, which hardens and sticks the reinforcing layers to the core.
  • the upper reinforcement layer forms a shell, but also a kind of skin that completely protects the core.
  • transverse holes 31 and 32 are produced for each of axes 6 and 7.
  • these holes do not pass through the wooden part, but through the battens 14 and 15.
  • a high rate of reinforcing fibers of the order of 30% for making the cleats.
  • a cylindrical insert is preferably inserted inside each hole in which is housed the axis.
  • ski blank undergoes recovery operations if necessary and operations finishing. These operations are not concerned with the subject of the invention, they are carried out in the usual way.
  • the drilling operation of the transverse holes is facilitated and carried out so more precise.
  • FIG. 9 represents a blank of wooden core 35 in which four longitudinal grooves 36, 37, 38, 39 have been machined.
  • the grooves are filled with cleats 40, 41, 42, 43 made of a moisture-resistant material.
  • the grooves and cleats are placed in the ski areas where, for example, the holes for the screws are provided of the retaining elements. In this case, the depth of the grooves and the thickness battens are greater than the length of the screws.
  • the core blank 35 is then machined to give the core its final form.
  • the cleats are also machined from so that their upper surface is flush with that of the rest of the core.
  • the assembly screw holes penetrate the battens and not more in the wooden part of the core. There is therefore less risk of water penetration or humidity in the core, and risk of swelling of the core near the holes.
  • the invention is not limited to wooden cores. It generally applies to cores whose material is likely to retain water or humidity.
  • the invention applies generally to any type of gliding board provided. to be used in a humid environment, especially on snow, ice or water.
