Definitions

  • the invention relates to a ski or a snowboard and a method for producing a ski or snowboard.
  • the FR 2748399 A1 discloses a ski with a device for vibration damping arranged on its upper side.
  • This device comprises at least two vibration damper arrangements which follow one another directly in the longitudinal direction of the ski and each consist of a layer of viscoelastic material and a rigid retaining plate. The bottom of this viscoelastic material is attached to the ski and the top of this viscoelastic material is attached to the rigid retaining plates.
  • These retaining plates are either rigidly connected to one another in pairs or in relation to the longitudinal direction of the ski when the ski body is unloaded, lined up without gaps, so that the retaining plates of the vibration damper assemblies support one another when the ski is subjected to bending loads or repel one another when the ski is unloaded.
  • the FR 2616340 A1 describes a ski with an elongated ski body, a cover layer being formed at least on its upper side.
  • a vibration damper is formed on the upper side of the ski body and consists of a layer of viscoelastic material over which a rigid plate protrudes.
  • the vibration damper is arranged directly in a recess in the cover layer.
  • the top of the plate is in the same plane as the top of the facing. Due to the recess in the top layer, the vibration damper is closer to the ski body and the vibration damper should be able to do its job better.
  • the vibration damper does not tend to accumulate snow or to interlock the two skis of a ski pair when the skis accidentally cross over.
  • the effectiveness of the vibration damper, the robustness and the manufacturability of the ski body are only partially satisfactory.
  • the object of the present invention was to overcome the disadvantages of the prior art and to provide a ski or a snowboard, as well as a method for its production, by means of which efficient damping of bending vibrations of the ski body is made possible with the least possible effort.
  • the ski according to the invention or the snowboard according to the invention comprises a multilayer gliding board body which defines or has a longitudinal axis running in the direction of its length.
  • the gliding board body comprises at least one strength-relevant upper chord, at least one strength-relevant lower chord, at least one core element arranged in between, at least one cover layer made of a plastic material forming the top of the gliding board body, and at least one tread surface forming the underside of the gliding board body.
  • At least one depression is embossed or molded into a surface of the at least one cover layer facing away from the core element. This at least one depression can preferably be shaped like a trough or essentially trapezoidal in cross section.
  • At least two, preferably at least three, small plates arranged at a distance from one another in the direction of the longitudinal axis are glued into the at least one recess.
  • These platelets are made of a material whose modulus of elasticity is higher than the modulus of elasticity of the plastic material of the cover layer of the gliding board body.
  • the ski according to the invention or the snowboard according to the invention has the advantage of a favorable cost-effectiveness ratio.
  • the at least two small plates glued into the recess have a positive effect on the vibration behavior of the gliding board body.
  • the restoring behavior of the gliding board body after an elastic deformation, in particular after an elastic deflection of its longitudinal axis can be improved as a result.
  • the quasi serially arranged platelets spaced from each other in the longitudinal direction of the gliding board body effectively dampen vibrations of the gliding board body at several oscillation frequencies occurring during use of the gliding board body or within several frequency ranges of the mechanical vibrations.
  • the flexural vibrations of the Cover layer of the gliding board body which are caused by alternating tensile and compressive loads on the cover layer in connection with elastic bends in the gliding board body, are particularly effectively damped or held back.
  • the spatial distancing of the individual platelets - and thus their predominantly independent development of action - also has surprisingly advantageous effects on the vibration behavior of the gliding board body. This can be explained by the fact that the individual platelets are assigned to the closest vibration nodes of the gliding board body or have an influence on their position in the longitudinal direction of the gliding board body.
  • a ski according to the invention or a snowboard according to the invention has a high level of robustness, since the at least partially recessed plates are well protected from undesired detachment.
  • the corresponding technical measures for damping vibrations of the gliding board body can be implemented relatively inexpensively, which favors the economy of the specified gliding board body.
  • the platelets each have a layer thickness between 0.05 mm and 2 mm, preferably between 0.1 mm and 1 mm.
  • a process-stable and high-quality embedding in the at least one depression in the upper side of the cover layer can be achieved.
  • a significant influence on the vibration or damping behavior of the elongated sliding board body can be achieved.
  • the platelets can be formed from metal, in particular from stainless steel, aluminum, or a metal alloy with iron as the main component. Due to the particularly high modulus of elasticity compared to the outer cover layer of the gliding board body, such platelets have a great influence on the vibration behavior of the gliding board body. In addition, metal platelets can be made relatively thin and still have a high influence on the vibration behavior or on the damping effect against vibrations.
  • the platelets are formed from a plastic material different from the cover layer or from a carbon composite material. This means that you can choose from a wide range of elasticity modules. In addition, a high-strength bond with the top layer can be achieved. Furthermore, unwanted plastic deformations of the edge sections or dents on the edge areas of the platelets are kept behind even when the gliding board body is subjected to intensive stress.
  • a configuration is also advantageous according to which an outer cover surface of the platelets is formed flush with the surface or slightly recessed with respect to the outer surface of the cover layer in an edge region around the recess.
  • a width of the platelets is between at least 20% to a maximum of 80%, preferably about 33%, of a width of the gliding board body in its longitudinal section with the recess.
  • a width of the platelets is between at least 20% to a maximum of 80%, preferably about 33%, of a width of the gliding board body in its longitudinal section with the recess.
  • the platelets can also be useful if the platelets extend over more than 10%, in particular between 15% and 70%, preferably between 20% and 50%, of the length of the gliding board body. As a result, such platelets can also exert a marked influence on the vibration behavior of the gliding board body.
  • the glued-in platelets cover more than 70%, preferably between 80% and 98%, of a base area of the depression. This creates a relatively intensive filling or almost the entire area of the base area of the depression. This makes it possible to achieve a high level of effectiveness of the arrangement with regard to the vibration behavior and influence on the bending stiffness characteristic of the sliding board body. In addition, this results in a reduced risk of undesired detachment.
  • a distance between platelets directly following one another in the longitudinal direction of the gliding board body is between 1 mm and 20 mm, in particular between 2 mm and 10 mm, preferably between 3 mm and 5 mm. These values relate to the unloaded state or to the state of rest of the gliding board body. This also allows the glued-on platelets to be highly effective can be achieved in terms of vibration behavior and influence on the bending stiffness characteristic of the gliding board body.
  • an adhesive layer in particular an acrylate adhesive
  • this adhesive layer is formed exclusively within an outer contour of the platelets.
  • an adhesive connection offers the advantage of a large-area or full-area connection with respect to the sliding board body.
  • this avoids penetration of the upper layers of the gliding board body and the problem of moisture penetration into the structure of the gliding board body is kept as low as possible.
  • assembly can be carried out quickly and reliably. In particular, there will be hardly any or no adhesive protruding or protruding from the base area of the platelets. Optical or mechanical impairments of the top layer are thus kept at bay.
  • this adhesive layer or an additional adhesive layer which is provided for the permanent connection of the platelets to a base area of the recess, has a smaller layer thickness than a layer thickness of the platelets.
  • the structural height of the platelets can be kept low compared to the upper side of the ski, whereby the tear-off strength or detachment security of the platelets can be increased.
  • a robust, vibration-damped and at the same time as economical as possible construction of the gliding board body can be achieved in this way.
  • the platelets have an essentially rectangular boundary contour.
  • the corner sections of these platelets can be rounded.
  • the production method according to the invention has the advantage of a favorable cost-effectiveness ratio.
  • the corresponding technical measures for damping vibrations of the gliding board body can be implemented relatively inexpensively, which favors the economy of the specified gliding board body.
  • high process stability can be achieved with high quality of the gliding board bodies produced or the preceding semi-finished products required for this at the same time.
  • the required manufacturing cycles for the gliding board bodies or for semi-finished products for the gliding board bodies to be processed later can be implemented quickly or kept short.
  • the embossing of the preferably trough-like recess in the cover layer and the gluing of the individual Platelets with the base of this recess executed simultaneously or in parallel.
  • these procedural measures ensure in an advantageous manner that a relative positioning that is as exact as possible and also with repeatable accuracy can be achieved between the individual platelets and the boundary edges or marginal areas of the trough-like depression. Undesired incorrect positioning or deviations from the target or plan position of the individual platelets are effectively avoided by the measures according to the claims.
  • the platelets are provided with an adhesive layer on their flat side facing the cover layer before they are introduced into the heating press. This makes it possible to achieve an efficient and, at the same time, particularly permanent attachment of the individual platelets to the top of the semi-finished product or to the surface of the final gliding board body.
  • a cover layer made of thermoplastic polyurethane (TPU) is provided for the production process.
  • TPU thermoplastic polyurethane
  • the embossing of the holding frame and the platelets into the cover layer takes place at a temperature of the cover layer between 100.degree. C. and 120.degree. C., preferably around 110.degree.
