Abstract

Snow sliding board has a surface formed from a layer of decorating foil. A layer from a meshed or lattice-like flat material is provided below the layer formed by the decoration foil for obtaining a structured surface. The meshed or lattice-like flat material possesses more hardness than the material of the decorating foil. An independent claim is also included for the method for manufacturing snow sliding board.

Description

The invention relates to a method for producing a snow gliding board, in particular skis or snowboards according to the preamble of claim 1 and to a snow gliding board according to the preamble of claim 9.

Snow gliding boards, in particular skis, whose outer surface on the Schneegleitbrettoberfläche and partly also on the long sides or side surfaces of a decorative film made of a plastic material, in particular of a thermoplastic material, such. ABS (acrylonitrile-butadiene-styrene Copolimerisat), polyamide or polyester are formed, are known in various designs.

The production of these snow gliding boards is usually done in molding or pressing tools, introduced into the or in the mold space, the individual components and components of Gleitbrettkörpers in the required position and then using a thermosetting resin or plastic by pressing together be joined to the sliding board body. Although the inner surfaces of the mold space have one of the outer contour of the Schneegleitbrettkörpers corresponding course (for example, for forming in the longitudinal direction of a ski body extending projections), but otherwise run as smooth as possible to u.a. to facilitate the demoulding and especially the cleaning of the respective mold.

Snow gliding boards, in particular skis and snowboards, which are profiled on their snow sliding board surface or surface formed by a surface or decorative film or provided with a multiplicity of trough-like recesses, are known by corresponding shaping or embossing of the surface or decorative film or but by placing a grid or fabric below the surface or decorative film, so that in the manufacture of the sliding board body whose eye surface form the trough-like depressions ( FR-A1-2 830 200 respectively. DE 102 43 310 A1 ).

The object of the invention is to show a simplified method for the manufacture of snow gliding boards, which have a light structuring on their snow sliding board outer surface formed by a surface or decorative film. To solve this problem, a method according to claim 1 is formed. A snow slide is the subject of claim 9.

One advantage of the invention is, inter alia, that molds with smooth inner surfaces can be used for the manufacture of the snowboard, and yet a visually appealing, light surface structure is achieved, so that not only a simplified cleaning of the molds is possible, but with a simplified design of the molds one and the same tools can also be used for the production of snow gliding boards with or without surface structuring.

Further developments of the invention are the subject of the dependent claims. The invention will be explained in more detail below with reference to the figures of an embodiment.
Show it:

Fig. 2

in a simplified partial view a section through the body of the snow gliding board FIG. 1 ,

In the figures, 1 is the gliding board body of a snow gliding board, for example, a ski or a snowboard of the conventional construction. The peculiarity of the sliding board body 1 is that this at 2 at the top, gfs. also is slightly structured on side surfaces in a special way, in addition to a color and / or graphic design.

How the particular FIG. 2 shows the Gleitbrettkörper or its core 3, which can be made in a variety of ways, also using a variety of materials, provided on the surfaces with a multilayer surface structure, which consists of several layers, from a the outer surface of the Schneegleitbretts forming layer 4 of a decorative film, as is commonly used for the surface of Schneegleitbrettern, for example of a thermoplastic material such as ABS (acrylonitrile-butadiene-styrene Copolimerisat), polyamide or polyester, from one of the layer 4 in the direction of Core 3 subsequent layer 5 of a mesh or sieve-like sheet. The latter consists of a material which, in particular under the conditions and temperatures which form the sliding body 1 during the production of the gliding board body or during the pressing of the individual Components in the manufacturing or molding prevail, has a greater hardness than the material used for the layer 4. The layer 5, whose thickness d _{5 is} also greater than the thickness d _{4 of} the layer 4 consists for example of plastic, in particular thermosetting plastic and / or a fiber material of another suitable material. Preferably, the sheet 5 forming sheet is an IPT network.

The layer 5 is followed in the direction of the core 3 by a layer 6 whose thickness d _{6 is} in turn greater than the thickness d _{4 of} the layer 4 and made of a suitable, resilient or elastic (eg soft elastic) material, preferably of an open-pored Material or foam material whose pores as well as in the layer 5 existing cavities are filled in the preparation with the used and preferably by curing thermosetting resin.

Although during pressing, the layer 4 against a smooth, unstructured inner surface of the in the FIG. 2 is generally applied with 7 indicated closed mold, the gliding board body 1 after its preparation on the outer surface formed by the layer 4 in a surprising manner the light structuring 2, which formed in replication of the network structure of the layer 5 of a variety of very shallow trough-like depressions is.

The decorative film forming the layer 4 preferably consists of a transparent material and is colored and / or graphically designed or backprinted on its surface side adjacent to the layer 5 in the respective desired manner.

The invention has been described above by means of an embodiment. It is understood that changes and modifications are possible without thereby departing from the inventive concept underlying the invention.
