Abstract

A ski or a snowboard has an upper surface with a decorated transparent facing material having a structured surface that is orientated in line with the ski or snowboard. The decorative facing material enhances the bond between the facing material and the ski or snowboard and enhances the aesthetic appeal with a three-dimensional effect. The inner face of the facing material in contact with the ski or snowboard is essentially non-structured or smooth. The facing material is e.g. self-adhesive transparent or metal foil.

Description

The present invention relates to a sliding board, in particular a ski, z. B. an alpine ski, Cross-country skis, jumping skis or a snowboard with one facing away from the tread of the ski Side applied decoration device.

In the prior art are a variety of sliding devices with special surface structuring known. DE-A-101 30 392 and the corresponding WO 03/000984 disclose Such sliding devices, their entire surfaces or parts thereof by structuring in the form of body-length elevations with intervening depressions combined with direction-independent microstructures provided with hydrophobic elevations are. The gliding devices according to DE-A-101 30 392 are intended to be aerodynamic and hydrodynamic frictional resistances be advantageous, in addition to the Pollution and icing tendency should be reduced.

Furthermore, in DE-A-102 43 310 a board-like sliding device is disclosed in which a plurality are provided between a tread covering and the cover layer arranged layers, which form a sandwich element with an interposed core. One from the core opposite outer side of the cover layer and / or the tread covering has at least partially a structured surface with a plurality of depressions or elevations on. The depth of the recesses is smaller than the thickness of the structured cover layer or the structured tread covering. It is found advantageous in DE-A-102 43 310, that by the finely structured surface of at least the cover layer of the cw value or drag coefficient of the sliding device can be improved. This should compared to gliders with perfectly smooth surface layers improved performance be enabled. Other sliding boards or skis, snowboards u. ä. with surface decorations are for example in DE-U-297 24 623, DE-A-36 36 645, DE-C-37 38 040, DE-A-41 06 911, DE-A-197 26 968, EP-A-0 606 556 and FR-A-2 563 741. In these Sliding devices, the decoration devices are multi-layered. This multi-layered Construction is difficult to handle manufacturing technology and expensive.

The present invention is based on the object, a sliding device with an optical To provide attractive and manufacturable easy to handle decoration device. This object is achieved with the features of the claims.

The invention is based on the idea, the sliding board, especially the ski or the snowboard, with a decoration device on the side facing away from the tread Side to provide, wherein the decoration device is formed like a film and a substantially smooth outer surface and an opposing textured surface having. The decorative element is attached to the structured surface on the ski body. Preferably, there is one or more between the gliding board body and the decoration device arranged several liners, z. B. in the form of a metal foil, a metal-containing Coating or metal coating.

The ski construction according to the invention is particularly advantageous in that the outer surface, d. H. the side facing away from the tread side of the ski, is smooth, at the same time by the structuring of the decoration device on the side facing the interior of the ski the possibility exists to achieve three-dimensional effects. These occur, for example particularly apparent when between the ski body and the decoration device a metal layer (eg metal foil, metal-containing coating and / or metal coating) is arranged. The decoration device is preferable for achieving this effect at least translucent and in particular transparent.

Another advantage of the present invention is that the structuring of the Decoration device on the side facing the ski core an enlargement of the surface As well as the surface roughness is achieved, so that a better and safer adhesion the decoration device is made possible on the ski body.
