Definitions

  • the invention relates to a ski with a tread part and a hollow ski body, the height of which, measured normal to the tread part, differs over the length of the ski.
  • a plastic ski has already become known from AT-PS 309 282, the upper flange and lower flange or its tread component and the surface component facing away from the tread have been connected to one another via longitudinal webs which are laterally offset from one another.
  • a hollow ski body is formed, the height of the webs being able to be selected by appropriate shaping of the machining so that a different overall height of the entire ski is achieved in the longitudinal direction of the ski.
  • a separate shape had to be used for each ski type and for each ski waist in order to form the corresponding cavities after connecting the individual components in the ski core.
  • such a formation of the hollow body with the respective side contour of the ski results in relatively difficult to control strength properties and relatively large fluctuations in the torsional behavior of the ski body.
  • the ski according to the invention essentially consists in that the ski body is designed as a hollow body with parallel side edges that run in the longitudinal direction of the ski, and that the width of the ski body less than or equal to the smallest width of the waisted tread part is measured transversely to the longitudinal direction of the ski. Because an essentially width-parallel ski body is designed as a hollow body, a defined and high torsional rigidity can be specified by simply specifying the respective height-width ratio.
  • such a component can be used to set the most favorable width-height ratio, in particular in the end regions, namely the regions of the blade and of the ski end.
  • the choice of such a wide parallel hollow body as the ski body now leads to the fact that, depending on the waist of the ski, the tread component projects differently laterally over the ski body.
  • the tread component can be distinguished by relatively good transverse stiffness and, in particular, uniform transverse stiffness, and the fact that the tread component protrudes laterally over the ski body leads in particular to improved ice grip due to the narrow lateral contact surfaces when the ski is edged.
  • the width of the ski body it is necessary, as provided according to the invention, for the width of the ski body to be less than or equal to the smallest width of the waisted tread part measured transversely to the longitudinal direction of the ski.
  • the ski body or hollow body according to the invention can advantageously be designed as a shell body and closed on the side facing away from the tread part with an upper belt component. Even when such a hollow body is designed as a shell body, there are significant advantages in terms of production technology. In this embodiment, too, the width of the ski body, which remains constant over the entire length of the ski, can be maintained, since the upper belt does not have to protrude in any way over the lateral edges of the ski body.
  • a core made of extruded profiles, which are endlessly manufactured and length can be cut to length, the thickness contour can be milled onto the upper and / or lower shell.
  • the design according to the invention is developed in such a way that side surface components which are matched to the outer contour of the tread part and whose height corresponds to at least part of the height of the hollow body are connected to the side edges of the hollow body.
  • Such side surface components attached to the side surfaces of the ski body for aesthetic or design reasons can easily be formed with a lower height than the height of the hollow body and can be formed, for example, over the entire length of the ski with a constant height.
  • This in turn has significant advantages with regard to the grip on the ice, since the lateral contact surface can be kept constant over the entire length of the ski when the ski is edged, despite the different thickness of the ski. It is of major advantage that these lateral components do not in any way have to contribute to the stiffness or elasticity properties of the ski, since the torsional stiffness and the desired material properties are already defined in themselves by the dimensioning and design of the hollow ski body .
  • the design is such that the hollow body is designed to be divided in the longitudinal direction of the ski.
  • a modular system for skis with different side facades can be used in a simple manner.
  • the design is advantageously made such that the side surfaces of the hollow body have an angle deviating from 90 ° with the tread plane.
  • the hollow body can be designed as a single or multi-chamber construction. Fiber-reinforced thermoplastics or thermosets can be used in a particularly advantageous manner as the material for the torsion box.
  • the subdivision of the hollow body in the longitudinal direction of the ski allows the different demands on the torsional properties in different partial areas of the ski to be taken into account in the longitudinal direction of the ski, and offers in particular the possibility of the middle area in a suitable manner for receiving bindings prepare to share.
  • the formation is advantageously such that the central part of the ski has a partial region of the same height in the longitudinal direction, wherein ski binding parts and / or ski binding fastening parts can be integrated in the central part of the hollow body.
  • the possibility of using extruded, endlessly produced profiles offers in a particularly simple manner the possibility of designing such that the hollow body consists of a plurality of profiles or chambers running in the longitudinal direction.
  • a hollow ski body of this type can, moreover, achieve a weight reduction with simultaneously improved torsional rigidity and, above all, the required torsional rigidity in the end regions of the ski can be more precisely controlled and adjusted.

  • the division of the hollow ski body 3 into a central region 8, an end region 9 and a front region 10, which is indicated in FIG. 1, allows the torsion or rigidity properties of the ski to be taken better into account.
