Definitions

  • the invention relates in particular to a ski in which a blank ski, usually consisting of belt layers. Core, outsole and, where appropriate, steel edges, a top of its top and its side surfaces is molded from a preferably elastomeric plastic.
  • Such a construction for skis is known, the casing being usually molded in one piece onto the raw ski, in a form in which the raw ski is inserted, after which the material of the casing in the remaining, the shell corresponding mold cavity is introduced.
  • a preferred embodiment of this process is the RIM (Reaction Injection Molding) process, by means of which polyurethane or its components, isocyanate and polyol, which are mixed with one another and with a dye in the spray head, are injected into the mold cavity. Usually pressures (in the mold cavity) of 2 to 15 bar are used. If, as is preferred, the result is to be an elastomeric polyurethane cover, this can be achieved by selecting and adjusting the components of the polyurethane.
  • the object of the invention is, in particular, to improve skis of the type mentioned at the outset, especially with regard to the mechanical-dynamic behavior of the ski.
  • the primary object of the invention is to optimize the bending characteristic of skis in such a way that harmful effects of the clamped ski boot on the bending line are largely avoided.
  • the invention is based on the knowledge that, in particular, the bending behavior of the ski is also influenced by the boot clamped on the ski in the binding, in the sense of a stiffening in the middle region of the ski, the simply curved, smooth "theoretical""Bending characteristic of the ski alone (without a clamped shoe) more or less deformed by clamping the shoe in the middle of the ski, ie it contains a" stiffening hump "(FIG. 11).
  • the measure according to the invention as can be seen from the schematic representation of the bending characteristic in FIG.
  • ski constructions have already been proposed which have elevations in front of and behind the standing area of the shoe, these are not measures for optimizing the bending characteristic curve when the shoe is clamped in, and the structure is also not made up of attachment parts which have a common shell are preferably made of elastomeric plastic.
  • the vibration behavior in particular the vibration damping, the torsion behavior, and the surface pressure distribution of the ski can also be influenced by the invention.
  • a special damping effect of the encased attachment parts also lies in the fact that the transmission of the vibrations of the ski to the foot or leg of the skier is dampened, which enables skiing to be carried out without fatigue.
  • the attachment parts are arranged over the top chord, especially if it is made of metal, and are attached to the top chord Covered directly or indirectly - ie with the interposition of one or more intermediate layers.
  • the attachments should have the lowest possible density, for example between 0.1 to 0.6 g / cm 3 .
  • foams also foam-fiber composites or other light materials (light woods, honeycomb core materials) come into consideration.
  • closed-cell foams can be used for the foams, which has the advantage that the specifically heavier plastic material of the casing does not penetrate into the attachments.
  • the penetration of the plastic material of the cover into the foam material of the cover can also be prevented in the case of open-cell or mixed-cell foam, if the surface of the add-on parts is painted or in some other way to ensure a closed outer skin.
  • a certain penetration of the plastic material of the casing into the material of the attachment parts can be advantageous for the connection of the casing and attachment. Then open-cell or mixed-cell foams should be used without a closed outer skin.
  • attachment parts these expediently have a wedge shape that increases towards the center of the ski.
  • attachment parts including the cover material have an overall height that increases towards the center of the ski.
  • this could also be achieved in the case of non-wedge-shaped attachment parts by merely varying (increasing) the thickness of the shell over the attachment parts in the direction of the center of the ski.
  • Parts of the ski binding can be connected to the front parts (or the shell sections thereof) on the end face (facing the shoe standing area) or can engage in the top parts. But you can also mount commercially available binding parts behind the front attachment part and in front of the rear attachment part on the shoe stand area.
  • the top of the shell or a separate surface covering in particular also have a longitudinal rib profile in the area of the attachment parts, which makes it possible to influence the torsional rigidity and the surface pressure distribution of the ski.
  • These ribs act in the sense of increasing the torsional rigidity.
  • a "softer" bending line can be selected with the same torsion. The result is that the stability of the bend is maintained while the ski is easier to turn. The ski accelerates excellently out of the curve. This effect also occurs on skis without additional attachments.
  • utensils or boxes for utensils into the surface covering or, in the case of a ski of the type mentioned at the beginning, into the areas of the plastic cover forming the ski surface, or to insert (glue in) recesses in the cover.
  • the utensils or the boxes or depressions therefor may also protrude into the attachment parts (i.e. if attachment parts are present).
  • utensils e.g. Consider: clock, thermometer, compass, lighting, reflector, avalanche search transmitter or receiver, data carrier for the control of ski lift access, valuables, keys, ski passes, altimeter etc.
  • the sheath is preferably made of an elastomeric plastic, e.g. Polyurethane, wherein the plastic of the casing is preferably molded onto the raw ski in accordance with the RIM process mentioned at the beginning.
  • the entire shell of the ski can consist of a uniform plastic or zones of different plastics (multi-component coating), although the zones of different plastics are cohesively connected to one another.
  • FIG. 1 shows a ski in side view or partially in section
  • Fig. 2 shows a plan view of the ski
  • Fig. 3 is a cross section according to III-III of Fig. 1
  • Fig. 4 to 6 show an attachment part for the rear ski in elevation (FIG. 4), in plan view (FIG. 5) and cross-section (FIG. 6)
  • FIGS. 7 to 9 show an attachment part for the front ski in elevation (FIG. 7), in Top view (Fig. 8) and in cross-section (Fig. 9).
  • 10 is 5 a cross-section according to XX of FIG. 1
  • FIG. 11 shows a schematic bending characteristic diagram of a ski with a non-optimized bending line. 12 uses a schematic bending characteristic diagram to illustrate the optimization of the bending line according to the invention.
  • the exemplary embodiment shown is an alpine ski which, as can be seen in particular from the cross sections according to FIGS. 3 and 10, consists of the following components: the upper flange 1 and the lower flange 2, e.g. from patiome
  • the core with a central part 3 ', e.g. made of wood, and side parts 3 ", e.g. made of foam, the steel edges 4 and the outsole 5 as well as a leveling layer 6 between the outsole 5 and the lower flange 2 (which can also consist of load-bearing material, e.g. glass fiber laminate).

  • the individual components of the ski are glued together and form the raw ski, which is inserted into a mold and with a sleeve 8 made of elastomeric plastic, e.g. Polyurethane
  • the individual components of the raw ski can be glued with the aid of adhesives and / or on the basis of the adhesion properties which the materials of individual components have in the processing state or by melting. Even between the material of the

  • the material of the casing can "mechanically” cling to the pores and recesses of the coated components.
  • a wedge-shaped attachment part 7 ', 7 " is arranged in front of and behind the shoe stand area 9.
  • An example of the shape of the attachment parts is shown in Figs. 4 to 9, in which the dimensions of Height, width and length are distorted. Ratio to the illustrated height of the attachment parts of, for example, 8 mm (rear attachment part 7 ', FIGS. 4 to 6) or, for example, 10 mm (front attachment part 7 ", FIGS. 7 to 9), the width is somewhat larger (rear attachment part 7 1, for example 58 mm, front attachment part 7 "(eg 55 mm) and the length can be considerably longer
  • rear attachment part e.g. 230 mm, front attachment part e.g. 240 mm With the rear attachment part 7 *, the width of the upper side decreases towards the center of the ski (with the same width of the base area of the attachment part), with the front attachment part 7 ", both the width of the upper side and the width of the base area towards the ski center decrease.
