Definitions

  • the invention relates to a board-type gliding device, in particular a ski or a snowboard, according to the preamble of claim 1.
  • One of the strip-shaped layers has groove-shaped recesses or bulges and extends essentially over the entire width and length of the ski body.
  • a damping layer of an elastomeric material is provided, which also extends over a greater part of the width and length of the ski body.
  • a hard, dimensionally stable filler is arranged between the elastomeric damping layer and the supporting function in the ski body, as it is arranged in the production of the ski body between the elastically resilient damping layer and the above, a supporting function in the ski body having position will store due to construction.
  • This dimensionally stable filler has been provided primarily for at least partial filling of the depressions on the upper side of the molded layer. Accordingly, the elastomeric damping layer and the bearing layers of the ski body are predominantly not in direct contact.
  • the elastomeric intermediate layer in the ski body will nevertheless form a critical weak point with regard to the constancy of the planned properties or with regard to the cohesion of the entire composite element, since this represents a highly stressed and extensive separation or transition region in the ski body.
  • a ski is presented with a core of injected or molded plastic.
  • This Schikern is from one porous, molded or molded plastic, such as polyurethane foam formed.
  • this porous core material is comparatively heavy, it has been proposed for weight reduction to form at least one cavity in the corresponding core material. This is accomplished by overmolding a hollow tubular member with the relatively heavy plastic, thereby saving plastic material for the ski.
  • the present invention has for its object to provide a board-like gliding device, especially a ski or a snowboard, with dynamic yet tolerant driving characteristics, which can reliably absorb the forces exerted on an integrated damping layer during deformation of the sliding device.
  • the advantage resulting from the features of the characterizing part of claim 1 lies in the fact that the gliding device, in particular a corresponding ski, offers surprisingly good driving properties, by making it considerably more tolerant, but nevertheless having a high liveliness and dynamics. This effect is achieved mainly by the quasi-elastic storage and embedding of the mold profile in the elastic plastic foam, after at least above or below the mold profile is formed in comparison to the stiffness of the mold profile relatively compliant, elastically compressible layer.
  • a high cohesion of the composite element or sliding device is achieved after the elastic insert layer for the mold profile is present only partially in the surrounding area of the mold profile and in the peripheral areas readily high-strength, the cohesion of the composite element ensuring adhesive or fillers can be arranged. Due to the elastic embedding of at least one shaped profile, a flexure element is integrated in the slider body, which is of decisive importance for the driving characteristics of the sliding device. In addition, a sliding device constructed in this way can be tuned very precisely and relatively easily to exactly those values which contribute to the creation of a sliding device almost ideal characteristics are required.
  • a relatively elastic plastic foam can easily form the core of the Gleit experts, without the required compressive strength of the Gleit expertss would be exceeded, after the integrated moldings to some extent as spacers between the upper layers and the lower layers or between the upper flange and the lower flange of the sliding device can function and yet the advantageous, elastic embedding is guaranteed at least one shape profile to a sufficient extent.
  • a limited elasticity of the core with progressively increasing deformation or compression resistance is achieved by the embodiment according to claim 4.
  • a relatively easy to produce Core component can be used with the desired elasticity or flexural rigidity, which can represent a simplification in the manufacturing process for the sliding device as a prefabricated unit.
  • Due to the configuration according to claim 9 can refer to the central region of the slider of the primary deformation stress thereof in the vertical direction down a higher resistance moment are opposed to the relatively lower bending stresses of the sliding device in the vertical upward direction.
  • a particularly compact, multi-layered bending or damping element for the sliding device according to the invention which can be included in a manufacturing process for the sliding device without any problems, is characterized in claim 10.
  • a sliding device which can be produced by a prior art injection method for foamed plastics, is characterized in claim 11.
  • a mold profile with a high utilization capacity of the available core area with relatively simple construction and trouble-free production is characterized in claim 15.
  • a particularly advantageous embodiment is characterized in claim 16.
  • a continuous core element with bridge-like longitudinal extent is achieved in an advantageous manner, wherein the load transfer points or the end regions of the molded sections extend into the outermost contact or contact areas of the sliding device with the substrate.
  • weak points or fractures vulnerable to breakage of the sliding device in the end region of the relatively dimensionally stable form profiles are avoided and in particular a harmonious bending characteristic can be achieved over wide areas of the sliding device.
  • a the relatively tight spaces in the end regions of the sports equipment bill bearing shape or double profile is characterized in claim 17.
  • a damping effect directed in the longitudinal direction of the sliding device or the shape profile is achieved by the embodiment according to claim 18 and can thereby be assigned to the relatively far-reaching relative movements between the front ends of the outer and inner shape profile well tunable damping layers.
  • a direct contact between the hard layers of the nested shaped profiles is prevented by the embodiment of claim 19 and also allows a weight reduction of the sliding device.
  • the embodiment according to claim 20 enables a free-swinging mounting of the inner mold profile relative to the outer mold profile and a sudden or significantly increasing bending moment characteristic of the mold profile unit or the entire sliding device.
