Definitions

  • the present invention relates to skis with an elongated hollow girder made up of at least two shells.
  • a ski with a hollow girder made up of two shells is referred to in the Specification of the German Gebrauchsmuster Specification 1,918,146.
  • One of the shells is in this case bent into an U-shape while the other is constructed as a substantially flat plate.
  • the two shells made of steel are welded in their edge parts and thus form a compound body with a high flexural and torsional stiffness.
  • the two shells have approximately parallel surface parts, with a spacing of at least 0.2 mm, at a position adjacent to each side wall of the ski, and these surface parts are connected together rigidly by means of a shock absorbing plastic.
  • the invention provides for simple production because the shells fitted together can readily be glued by the shock absorbing plastics material.
  • the plastics layer increases the damping properties in a particularly favorable manner.
  • a hollow girder of duralumin with a thickness of 1 mm made up of two U-shaped shells which were glued together at their side edges with a spacing of 1 mm using polyurethane.
  • the dimensions of the hollow girder were 500 X 70 X 8 mm.
  • the construction in accordance with the invention thus provides for a substantially better damping effect than welded aluminum constructions or present high quality plastic skis.
  • polyurethane as a plastics material because this material has good adhesive properties and in accordance with the invention also has excellent damping properties.
  • At least one of the shells has an U-shaped cross section whose limbs are arranged with a spacing from the associated surface parts of the other shell. It is, however, particularly advantageous for the two shells to have an U-shaped cross section, the limbs being connected by a plastics material layer of 0.2 mm in thickness. In this respect at a position adjacent to the connecting position of the two shells steel edge strips can be provided which are preferably made so that they can be interchanged.
  • the shells are made of a metal, for example aluminum or steel.
  • the ski in accordance with the invention can be particularly economically produced by a method in which the two pre-fabricated shells are first fixed together loosely to form a hollow girder, then heated in a mold preferably to a temperature above C and then at least in the zone of the spaced surface parts filled with plastics material.
  • a foam material body can be placed inside which at least partially fills the cavity of the girder to be formed.
  • a foam body can be placed inside in a mold and have plastics material cast round it. The plastics material surrounds the hollow girder in one piece giving it its external profile and sticks together the spaced surface parts of the shell.
  • FIG. 1 shows a ski in side view schematically.
  • FIG. 2 shows a hollow girder made up of two shells, in cross section schematically.
  • FIG. 3 shows a hollow girder similar to FIG. 2 schematically.
  • FIG. 4 shows a somewhat differently shaped hollow girder in cross section.
  • FIG. 5 shows schematically a hollow girder made up of two U-shaped shells.
  • FIG. 6 shows schematically a hollow girder corresponding to FIG. 2 but somewhat altered in details.
  • FIG. 7 shows a glued joint with a varying thickness.
  • FIG. 8 shows part of a shell with recesses.
  • the ski shown in FIG. 1 has at least one part of its length as an elongated hollow girder l, which is made up of at least two shells.
  • the two U-shaped shells 2 and 3 are provided in this first embodiment.
  • the base surfaces 4 and 5 form the top and bottom sides of the ski.
  • the two shells 2 and 3 have parallel surface parts formed by the U-limbs, which are arranged with a spacing between each other. The spacing amounts to at least 0.2 mm and is intended for receiving the shock absorbing plastics material, such as polyurethane, which connects the two shells 2 and 3.
  • This plastics material glues the shells 2 and 3 together to form a flexurally and torsionally stiff compound body whose flexural and torsional vibrations are considerably damped.
  • FIG. 2 has steel edge strips 8 arranged in a replaceable manner adjacent to the connecting point between the two shells 2 and 3.
  • the strips 8 are fixed in one of the two side walls of the shells. Furthermore in the cavity formed by the two shells there is a foam material body 9 extending along the whole length of the hollow girder and fills up this cavity at least partially.
  • FIG. shows schematically two U-shaped molded girders 3, 4 which are encased with polyurethane 1 1.
  • the adhesive layer 10 connecting the girders 3 and 4 at their side surfaces 6 has a thickness of approximately 0.8 mm.
  • the girders 3 and 4 are encased with a polyurethane layer 11 and form a cavity, which is filled with a foam material core 9.
  • the side faces 6 of the girders 3 and 4 carry external steel strip bodies 8.
  • FIG. 7 shows partof a hollow girder with a connecting part 11 of different thickness; which is filled with plastics material.
  • FIG. 8 shows a shell 2 with recesses 12 which are arranged for modifying the running properties of the ski.
  • a ski comprising at least two elongated hollow girders forming shells and being U-shaped, the shells having surface parts which are generally parallel and have a spacing of at least 0.2 mm at each side wall of the ski, the surface parts being connected together allowing relative movement by a shock absorbing plastics material to form a vertically aligned shock absorbing sandwich structure.
  • a ski in accordance with claim 1 in which the breadth of the joint gap varies as seen in cross through the ski along the length of the limbs.
