Abstract

Snow gliding board, in particular ski or snowboard consisting of an upper part and a lower part, wherein the lower part is intended to rest on the snow and has a covering; and wherein the upper part has at least one core, wherein the lower part and the upper part are manufactured separately.

Description

The present invention relates to a snow gliding board consisting of a lower part (covering and lower flange) and an upper part (core, side cheek and upper flange) and a method for producing such Schneegleitbretter.

From the state of the art for mass production mainly sliding boards in sandwich and cap construction are known, also exist for the production of sliding boards different foaming.

The sandwich construction is a layered structure of glued together laminates. You start building from the bottom with the flooring, the edges and a support for the edges. Subsequently, a scrim made of glass or carbon fibers or other materials (bottom chord) and, if required, often a metal layer is inserted. This is followed by a core, depending on the construction, also a core end laterally, side cheeks and above the core again fiber lay (top chord) and if necessary metal scrim.

The conclusion is a cover layer. The blank thus prepared is fixed in the mold and glued with epoxy resins under heat and pressure in a press. Thus, the lower and upper straps are permanently connected to each other. Regardless of the materials used in this type, all interconnected layers more or less closely follow the dimension and width of the side mold or edge of the snowboard, which leads to a design-related limitation of the design options and handling characteristics of the sliding board.

From the DE 41 30 110 Skis are known which consist of a lower and upper belt and are made in sandwich construction. According to the there shown 7 is a cross-sectional area of the ski 1 with a multilayer sandwich component 45 as upper belt 2 shown. The sandwich component 45 is due to the surface layer 9 , the top layer 10 and the interposed intermediate layer 11 and one in the intermediate position in the longitudinal direction and approximately symmetrical to a Schimittelachse 46 integrated arranged support and / or damping element 47 educated. The top 13 of the upper belt 2 is concave transverse to the Schilängsrichtung and in the direction of the longitudinal side edges 37 the slope formed sloping. The support and / or damping element 47 can optionally be formed of different materials to achieve desired driving characteristics. For example, it is also possible to use the reinforcing and / or damping element 47 in the form of a spatial lattice girder in the intermediate layer 11 to arrange integrated, whereby high strength and resistance values are achieved at a low component weight. To achieve a planar mounting area 28 can the sandwich component 45 in the assembly area 28 in the depression 29 of the core 4 to be ordered.

In the cap or shell construction, the upper and the side cheeks consist of one piece. The resulting shell encloses the nucleus and girths to the edge.

In the different forms of the foaming process (injection process, composite construction and RIM construction), the upper, lower belt and core are connected by means of polyurethane foam. The shape and dimension of the layers used are also largely identical in this design, which leads to the design-related disadvantages already described.

The existing prior art restrictions on the production and design of the different structural elements make mass production of personalized, tailored to the individual driver characteristics snow gliding boards and a material, weight and resource-saving design impossible.

The object of the present invention is to overcome the mentioned as well as still further disadvantages of the prior art.

This object is achieved by the snow gliding board with the features according to claim 1 and by the method for producing snow gliding boards with the features according to claim 4.

The snowboard according to the invention, in particular ski or snowboard consists of an upper part and a lower part, wherein the lower part is intended to rest on the snow and has a covering and is optionally provided with edges; and wherein in a preferred embodiment the top is intended to receive a binding and has at least one core, the top and bottom being made separately.

According to the invention, it is also possible that the binding is not fixed on the upper part, but is fixed on the lower part. In this case, the upper part will either have a recess through which the binding extends. But it is also possible that the upper part is divided into two and is arranged in front of and behind the binding. It is also possible that the upper part has holes or holes through which the fixation of the bond with the underside takes place.

Advantageously, the upper part in shape and dimension is smaller than the lower part, in particular, the upper part has a smaller length and / or width.

Advantageously, the connection between the upper part and lower part is detachable.

The Scheegleitbrett invention has the advantages that the two elements can be mass production technology produced in large numbers. Since the lower parts are subject to a greater mechanical load due to abrasion and edge damage, it is advantageous if this part of the snowboard according to the invention, for example. Ski or snowboard can be replaced from time to time. The upper part, however, is largely responsible for the behavior of the ski or Schneegleitbretts and is not subject to high wear.

However, the damping behavior and the flexibility of the ski or snowboard can be significantly influenced by the mechanical properties of the upper part and the nature of the connection to the lower part.

By varying the dimension and shape of the upper, it is possible to tailor the characteristics of the ski or snowboard to the skier's requirements or abilities. In particular, this relates to the length and width, but also the contour, for example, the lateral contour line of the upper part, but also the thickness of the upper part or the course of the thickness over the entire length of the upper part. This variation possibility can also influence the design of the side cheeks

In addition to the possibility of optimizing the running characteristics of the ski or the snowboard by the shape of the upper part, there is the possibility of using these side cheeks for aesthetic measures, such as coloring by forming a side wall at the edge regions of the tops.

The ski according to the invention or snow sliding board according to the invention is produced by using the method according to the invention, wherein in a first step, the lower part is produced and in a second further, separate step, the upper part is made and in a final step, the lower part and the upper part are detachably connected to each other ,

Due to the separate production and largely independent design of the lower and upper parts, the production method according to the invention makes possible a material-saving, weight-optimized construction which is adapted to the driving style and weight of the respective driver.

Due to the separate production of upper and lower parts, it is also possible to perform a quality inspection of the respective items before joining, so that in case of any production errors not the complete snowboard, but only the defective element must be disposed of.

In case of wear of the much higher stressed base, there is also the possibility to replace only the lower part of the Schneegleitbretts after the connection of the two elements has been solved.

Furthermore, the invention enables an improved personalization of the snow gliding board. By using different materials in lower and upper skis as well as prefabricated stronger or weaker tops and the application of different joint materials in the joint (for example glue joint) between the two elements, the snow skimming board can, regardless of the size of the rider on his individual weight and that of be adapted to him preferred driving characteristics.

Finally, the invention enables a shaping of the upper part so that it simultaneously serves as a guide / suspension for a binding.

The geometry according to the invention also leads to a reduction in weight, as the use of material is reduced and the geometry of the snow gliding board is optimized.

The geometry of both elements can be adapted as far as possible free to the technically functional requirements and optical wishes of the buyer.

The snow sliding board or ski geometry according to the invention not least creates a novel appearance, since the side line and the side cheek no longer have to run along with the edge.

Other objects, features, advantages and applications of the construction method according to the invention will become apparent from the following description of exemplary embodiments with reference to the drawings.
