Definitions

  • the invention relates to a ski with a core made of light material, such as. B: Poplar wood, fir wood or foam plastic, with upper and lower layers of high-strength material, such as B. fiber-reinforced epoxy resin and / or light metal, which are preferably combined to form a torsion box surrounding the core, and with a parallel to the top of the ski essentially only in the binding area extending holding plate assembly into which holes can be made for receiving screws, which the heel and can bind the tip of the ski boot binding parts with the ski, the holding plate assembly inside the ski body via elastomeric intermediate layers such.
  • B. rubber or silicone rubber is stored, which are integrally (so firmly adhering, z. B. by gluing) connected to both the mounting plate assembly and the ski body.
  • the retaining plates in the ski are not only movable in the longitudinal direction of the ski as desired, but also in the transverse direction of the ski, so that the connection of the boot to the ski is flexible not only in the longitudinal direction of the ski but also in the transverse direction of the ski.
  • the skier's direction changes only with a certain delay. This not only affects the ski guidance, but can ultimately also endanger the skier.
  • Another serious deficiency is that with this construction the area in which the fastening screws can be attached is very small, so that the ski is restricted to the use of a certain type of binding.
  • the invention provides a new type of ski which has the advantages of the construction described above without the disadvantages thereof, that is to say a ski in which the binding can be fastened in such a way that neither the binding nor the ski boot has a substantially stiffening effect on the binding region of the ski.
  • the binding can be connected to the ski with little effort.
  • the connection of the binding parts to the ski is such that the flexibility of the connection exists only in the longitudinal direction of the ski, but not in the transverse direction of the ski. This leads to optimal guidance.
  • the entire binding area is suitable for receiving the screws to hold the binding.
  • the invention solves the stated problem by the training according to claim 1.
  • the plate is preferably formed from an aluminum sheet. A thickness of approximately 1 mm has proven itself for this.
  • the plate can also consist of a high quality fiber-reinforced plastic material, or also be a composite panel made from at least one thin metal layer and optionally fiber-reinforced plastic.
  • the holding plate above and below i.e. with its two large surfaces via thin elastomer layers cohesively connected to the ski body
  • the displacements required for deflection or deflection of the ski between plate parts and corresponding parts of the ski body take place with deformation of the elastomer layers without that the stiffening forces of the binding and the ski boot significantly counteract this.
  • the large-area connection between the holding plate and the ski body over the entire binding length ensures perfect lateral guidance of the ski through the binding.
  • the elastomer layers will usually be rubber layers.
  • the elastomer layers can advantageously have thicknesses on the order of 0.5 to 1 mm. You should be highly elastic, such as. B. the rubber of the tread of motor vehicles.
  • the side edges of the plate can lie directly against the side walls of the fiber-reinforced plastic torsion box, which surrounds the ski core, which is made of wood, for example.
  • the plate can be supported laterally against the torsion box or corresponding other fixed parts of the ski body, but also via narrow elastomer strips. These elastomer strips, which are then advantageously integrally connected to the upper and lower elastomer layer, allow a longitudinal displacement between the ski body and the plate, but counteract a transverse displacement between the ski body and the plate.
  • the plate extends in the longitudinal direction of the ski only under the binding area, that is, only as far beyond the screwing-in points in question for the binding as close to the front and rear as this to hold the screws even the longest binding is necessary, it has no disruptive influence on the other parts of the ski.
  • the length of the plate for a ski of customary length will be around 60 cm.
  • the invention allows the holding plate with its elastomer layers between, due to the small thickness of the holding plate and elastomer layers, which together will not be much thicker than about 2 mm in practice, without or with almost no weakening of the core or increase of the ski in the binding area to arrange the core and the upper high-strength layer.
  • a ski that is provided with a plate for receiving the binding fastening screws in the manner described can easily be provided with a binding. For this purpose, when drilling the holes for receiving the fastening screws, these holes will be lowered wider in the upper area, so that the plate is exposed upwards. Then it is sufficient if the binding parts are supported directly or indirectly on the plate when fastening by means of the screws.
  • a ski with screwed-on binding parts is characterized in that the binding parts are screwed against the plate by means of spacers extending through recesses in the upper layer of high-strength material. Since the spacers in the recesses of the upper, high-strength layer can move towards the latter, the ski boot with the binding and the plate can form a relatively rigid body, which is guided in the ski in a flexible manner via the elastomer layers surrounding the plate, without causing the ski to bend to significantly influence the rigidity of the plate, the ski boot and the binding.
  • the binding parts must therefore not clamp the upper, high-strength layer between themselves and the plate. So you should sort of like resting on the pillars on low columns, which protrude through the high-strength layer with air.
  • the binding parts can be flat sheets in the usual way. These can be used as "supporting pillars" with downwardly pressed bowls which have through holes for the screws in the middle.
  • the spacer elements are formed by flat washers in the manner of washers, which surround the screws and are so thick that there is still a slight amount of air between the surface of the ski and the binding parts.
  • the spacer elements can hold the binding parts, for example, at a distance of a few tenths of a millimeter from the ski surface.
  • the front and rear end faces of the plate should lie opposite the most flexible parts of the ski body, for example corresponding end faces of the wood or foam core. Small cavities can also be provided here. These can be kept free in the manufacture of skis, for example, by gluing small foam cords with a cross section of, for example, one square millimeter to the front and rear end faces of the plate or partial plate before the ski is manufactured.
  • the front and rear end faces of the plate or partial plate are preferably supported against the ski body via volume-variable elastomer parts. This is in turn preferably effected in that the elastomer layers covering the plate at the top and bottom are simply brought together here without the front and rear edges of the plate being sharpened accordingly. This creates small voids here. These are already sufficient to absorb the slight displacements that occur when the ski bends without correspondingly changing the length of the plate.
  • the ski shown has a wooden core 1, which is surrounded in the usual way by a torsion box 2, which consists of a fiber-reinforced layer of epoxy resin.
  • the upper and lower walls of the torsion box form the upper and lower layers of high-strength material.
  • a thin aluminum plate 3 reinforcing this wall runs under the upper wall of the torsion box 2 and is not shown in FIG. 2 for the sake of simplicity.
  • the ski is surrounded on the outside by a cover layer 4. At the bottom he has an outsole 5 and steel edges 6.
  • the base plates 8 of the automatic heel unit and the front jaw of the ski binding which are only shown schematically, are fastened to the top of the ski body by means of screws 7. Otherwise the ski binding is not shown.
  • an aluminum plate 10 extends underneath the light metal layer 3 which extends over the top of the torsion box 2 and which, as can be seen from FIGS. 2 and 3, is covered at the top and bottom by rubber layers 11 and 12.
  • the rubber layers 11 and 12 extend over the entire width of the ski and are integrally connected to the aluminum sheet 3 and the aluminum plate 10 or the wooden core 1 and the aluminum plate 10, for example by vulcanizing or by gluing with hardened epoxy resin.
  • Fig. 3 which shows only one half of the cross section of the ski, both rubber layers extend over the full width of the ski.
  • the upper rubber layer 12 extends forwards and backwards somewhat over the length of the aluminum plate 10.
  • the lower rubber layer 11 which runs in the manner shown in FIG. 2 at the front and rear end in the recess of the wooden ski core 1 receiving the two rubber layers and the aluminum plate 10 up to the surface of the core.
  • This recess can be made in a simple manner by milling.
  • the invention allows a very flat cutout to be used, so that the bending behavior of the ski is only slightly influenced.
  • the ski can also be made without milling. Then the plate arrangement with its elastomer layers lies between the un weakened core and the upper layer 2.
  • the front and rear edges of the sheet metal plate 10 and possibly also the elastomer layers can be sharpened so that the resulting approximately 2 mm high increase in the middle of the ski their ends steadily fall down.
  • the aluminum plate 10 is supported on the sides against the side walls of the torsion box 4, as can best be seen from FIG. 3.
  • the side walls of the aluminum plate are also blunt, as can also be seen in FIG. 3.
  • the aluminum plate 10 can also extend up to the side walls of the torsion box 2, or, if this is not present, up to the side covering of the ski body.
  • the ski comes out of production. Usually, it is only the binding that is provided by the dealer.
  • four screw holes are drilled through to the aluminum plate 10 for each of the two plates 8 in the exemplary embodiment.
  • a drill with a countersink is used, which at the same time as drilling the threaded hole for the screw in the sheet 10 has an enlarged hole 16 through it upper high-strength layer 2 and the upper rubber layer 12 countersinks down to the upper surface of the aluminum plate 10.
  • the binding parts 8 are then screwed to the aluminum sheet 10 with the aid of washers 17 shown exaggeratedly high in FIG. 3 and the screws 7.
  • the washers 17 are so high that they carry the binding plates 8 at a short distance from the surface of the upper cover layer 4.
  • the bond through the high-strength upper layer of the torsion box is directly connected to the aluminum plate 10, without the binding being able to exert disruptive forces on the upper high-strength layer of the torsion box when the ski springs through .
  • the aluminum plate 10 is firmly guided on the side walls of the torsion box 2.
  • the lateral end face of the aluminum plate 10 can be coated with a release agent before the ski body is pressed in, so that it is not integrally connected to the torsion box 2. It can be seen from FIG. 2 that, for example, when the ski springs through with the binding region down, the top of the torsion box 4 is shortened without the attachment of the binding with the aluminum plate 10 substantially counteracting such a shortening. The air between the washers 17 and the holes in the high-strength layer 2 is sufficient for this. The resulting longitudinal differences between the aluminum plate 10 and the top of the torsion box 2 are absorbed by corresponding shear deformations of the upper rubber layer 12. The same applies to relative changes in length between the ski core and the aluminum plate 10.
