Definitions

  • the invention relates to a ski. or the like .. with a torsionally rigid core insert in the manner of a composite body consisting of at least one plate-shaped longitudinal belt and a zigzag or undulating profile or the like, the profile and the longitudinal belt being connected to one another with line contact running transversely to the longitudinal direction of the ski.
  • the flexural rigidity and torsional strength are of particular importance for the skiing properties of a ski, the flexural rigidity sliding properties, smooth running, adaptability to bumps and the like. The like. Influenced and the torsional strength is decisive above all for the behavior of the ski when using edges. In order to be able to influence these properties, which are so important for the behavior of the ski, there are various types of core inserts for the ski, and composite bodies with zigzag profiles inserted in the form of a truss between the upper and lower flange have already been proposed.
  • the invention is therefore based on the object to overcome these shortcomings and to create a ski of the kind whose core deposit without any special design effort largely independent choice of the torsion - allows the ski and bending properties.
  • the invention solves this problem in that the profile on a as. only Lärgsgurt provided base plate and, as is known, is embedded in elastic filler. Due to the combination of the profile with a single longitudinal belt and the connection points between the profile and the belt, which are limited to transverse lines, a composite body of high torsional rigidity and little impaired bending softness is created, so that the core insert desired for ski construction is obtained in a simple manner.
  • the torsional stiffness can be selected by choosing the profile, by varying the wall thickness, profile profile, profile height, profile structure, material, etc. can be changed within wide limits and adapted to the desired conditions, and the achievable flexibility can be influenced within a wide range by the design of the base plate and the properties of the chosen filler material.
  • Torsional rigidity and flexibility are largely independent of each other, since it makes the connection along transverse lines between the profile and base plate hardly noticeable with regard to the bending properties of the composite body, but the profile with its individual profile elevations, together with the base plate through this connection, forms bending-resistant associations oriented transversely to the longitudinal direction of the ski, which have a correspondingly high level Ensure torsional rigidity and an optimal adjustment of the strength course over the entire length of the ski.
  • the filling material has a vibration-damping effect and allows the absorption or compensation of the profile movements that occur during bending.
  • the core insert according to the invention thus allows the construction of a particularly torsionally rigid ski even with a high degree of flexibility and offers optimal conditions for ski construction. Of course, this insert could also be used for other construction elements that require flexibility and torsional rigidity.
  • the base plate and / or the profile is broken through like a grid.
  • This opening of the profile or the base plate not only saves material and weight, but also allows the combination with additional strand material to increase the bending strength, which strand material can be passed through the perforation of the ski length.
  • These openings can be made as desired, e.g. be punched, but the profile can also be formed from the start from appropriately perforated material or mesh material.
  • a core insert (1) which consists of a base plate (2) and a profile (3) in the manner of a composite body.
  • the profile is zigzag-shaped in the longitudinal direction of the ski and rigidly connected to the base plate (2) along the edges (4) which sit on the base plate (2) and represent the mutual lines of contact, so that this insert (1) allows the construction of a ski , which is correspondingly flexible, but is torsionally rigid to the desired extent.
  • the profile (3) is embedded in the ski in an elastic filling material, which on the one hand can influence the bending properties itself and on the other hand the profile movements arising during bending can be absorbed or a damping effect for bending vibrations is achieved.
  • the torsional strength properties can be adapted to a wide variety of conditions and requirements and by suitable changes in the profile course, these strength properties can also be varied according to the ski length.
