Definitions

  • the present invention relates to a method for manufacturing a ski with attached end piece (s), that is to say with an attached tip and / or heel. It also relates to a ski produced by this process.
  • skis in particular downhill skis or alpine skis, for which the tip and often the heel are separate elements, and therefore constituting end pieces which are attached to the two respective truncated ends of the ski.
  • Advantages of this type of arrangement are detailed in document FR-A-2,544,210 of the Applicant Company. In general, it is particularly advantageous in terms of safety, performance, as well as manufacturing convenience.
  • the object of the invention which aims to remedy these drawbacks, is to propose a method for manufacturing a ski with a tip and / or added heel which allows an embodiment for which this tip and / or this heel can be relatively thin, light, aesthetic well integrated into the body of the ski, and in particular blend harmoniously with it by the fact that they can advantageously be formed in the form of end caps of the same thickness as the truncated end of the ski on which they respectively come to relate, so that the transition is then carried out continuously, without real break of the ski line.
  • a ski the front end and / or the rear end of which has a prominent post which is wide and thinner than the ski itself, this prominent post being intended to receive:
  • a ski which roughly consists of a central body 1 at the two ends of which are attached two plastic tips, including a tip 2 to the front which constitutes an attached spatula and a tip 3 at the rear which constitutes an added heel.
  • the sliding sole 4 and the decor layer 8 are both a little shorter than the other three layers which are formed by the core 6 sandwiched between the two solid reinforcing layers 5 and 7. They end, in front of or behind the body 1 of the ski, approximately 3 centimeters below the corresponding end, respectively 9 and 10, of the body 1 of the ski, thus defining, at the front as at the rear of this body 1 , a protruding stump or tenon, respectively 11 and 12, on which the insert is tightly plugged, therefore respectively the tip 2 and the heel 3.
  • the two shoulders 13 and 14 are coplanar.
  • the attached plastic spatula 2 is at its base substantially the same thickness as the adjacent section of the body 1 of the ski, or about 7 millimeters to fix ideas, and that in any case it is shaped so that the transition with the body 1 is carried out almost continuously, it being understood that in practice, for obvious manufacturing reasons, such continuity cannot be perfect and that there will always remain a small "stair step" at the transition between the ski body and the tip.
  • this tenon 12 being likewise defined by two shoulders 15 and 16, and the added heel 3 also being shaped in thickness for, after being tightly embedded on the tenon 12, introduce practically no, or very little, breakage on the staircase at the transition with the body of the ski.
  • the invention allows the precise production of these upper shoulders 14 and 16, directly to the mold and without any rework machining.
  • a first form of the process is based on the use, on the spatula side and the heel side respectively, of a "false part" coming, in the mold only, to extend the corresponding truncated end of the decor layer 8.
  • This false part therefore has the same thickness as the decor layer 8, and it fills the missing upper part, both at the front for the front false part 17 ( Figures 4,6, and 7) than at rear for the rear false part 18 ( Figures 5 and 8), of the body 1 of the ski.
  • Its shape here is trapezoidal, as shown in Figures 4 and 5.
  • a mold 19 is used, the bottom of which has, at the front on the spatula side ( Figure 6) as at the back on the heel side ( Figure 8), a respective overhang 20.21 in step form which defines a respective shoulder 22,23 complementary to the aforementioned lower shoulder 13,15 of the corresponding stud 11,12, this overhang being provided over the entire length of said stud.
  • Figure 6 shows, in exploded view, most of the constituent elements of the stack which is produced in the mold 19, while Figures 7 and 8 show these same stacked elements and the lid 24 of the closed mold.
  • the exploded view of Figure 6 only concerns the tip side, but it is of course exactly the same on the heel side.
  • the cover 24 is then put in place as illustrated in FIGS. 7 and 8, then the conventional operations of pressurizing and temperature of the assembly are carried out.
  • the body 1 of the ski is then formed. After the conventional deburring and sanding operations, the tip 2 and the heel 4 are added by narrow embedding and gluing or clipping on their respective tenons 11 and 12. The ski is then finished.
  • one or more reinforcing plates can also and conventionally be introduced into the mold at the level of the pad area, in particular to allow easy fastening of the fasteners.
  • FIG. 10 illustrates a variant of the process which has just been described, and which makes it possible to dispense with the false part 17.
  • the cover 24 of the mold has, on its internal face, an overhang 26 in the form of a step which is symmetrical with the lower overhang 20 of the mold 19 and which is therefore directed towards the interior of the mold.
  • This overhang 26 replaces the false part 17 and therefore has the same dimensions as the latter. It is therefore, like the latter, of complementary shape to the missing part of the ski which defines the above-mentioned upper shoulder 14 as well as the upper face of the tenon 11.
  • the rear false part 18 can be replaced by an overhang of the cover 24 which is the symmetrical of the rear overhang 21 of the mold 19.
  • FIGS 11 to 13 show another variant of the method according to the preceding figures 6 to 9, as well as the ski obtained according to this variant.
  • the core 6 is shorter, and it stops just before the tenon 11 which receives the spatula 2.
  • the two reinforcing layers 5,7 as well as the sole 4 and the decor layer 8 are all four longer, so that finally the post 11 is no longer formed, as previously, by the ends of the core 6 and the two reinforcing layers 5,7, but is now formed by the ends of the two reinforcing layers 5,7, of the sole 4, and of the decor layer 8.
  • the lower missing part which is filled by the overhang 20 and the upper missing part which is filled by the false part 17 have a total thickness between them. which then corresponds to that of the missing part of the end of the core 6.
  • the core 6 can be shortened at its rear end, to result in the birth of the rear stud 12, this core being there also replaced, in this stud 12, by an extension, in the stud, of the sole 4 and by an extension, in the tenon, of the decor layer 8.
  • the tenons 11 and 12 are each a multilayer complex which is produced by the superimposition of the non-truncated ends of the core 6 and of the two reinforcing layers 5,7, the sole 4 and the decor layer 8 being truncated accordingly
  • these same studs are each a multilayer complex which is produced by the superposition of the non-truncated ends of the sole 4, two reinforcing layers 5,7, and decor layer 8, the core 6 being, however truncated accordingly.
  • the core 6 stops just before the stud 11 or 12, and therefore does not form part of it, the two superposed reinforcing layers 5,7 then forming together a sufficiently solid core for this tenon 11 or 12.
  • the invention is not limited to the exemplary embodiments which have just been described. It lends itself very well to the production of skis with tip 2 and / or heel 3 added and asymmetrical, as shown diagrammatically in Figure 14.
  • Figure 15 it is even shown that the invention makes it possible to make a tip ski 2 and / or added heel, the visible line 25 of connection with the body 1 of the ski is a complex and tormented line which would in no case have been achievable by machining.
  • the false part and / or the mold base like the end of the decor layer 8 or of the sole 4, have a shape corresponding to the visible line 25.
