Abstract

A v-shaped gap (4) is created in a first step at the rear after the production of the basic board (2) which is slightly bent upwards at both ends (2.1, 2.2). The gap (4) is filled with a thermoplastic material and both surfaces of the area are smoothened with a suitable method. In a third step the insert (3) is shaped in order to create a v-shaped recess at the lower side for a better sliding characteristic of the snow board (1, 2). An additional circular insert (3') can be positioned in the front area (2.2).

Description

The invention relates to a snowboard, for example, snowboard according to the preamble of claim 1 and to a method according to the preamble of claim 13.

The object of the invention is to show a snowboard with improved handling. To solve this problem, a snow sliding board is designed according to claim 1.

A method for producing the snow gliding board is the subject of patent claim 13.

By using a thermoplastic material for the at least one insert, it is possible to use this insert initially in a recess which does not have the recess at the bottom of the insert, i. to mount the non-curved shape in the gliding board body, then to mechanically machine the underside of the gliding board body and the underside of the insert, i. to grind, so as not only for the bottom of the sliding board body, but also for the bottom of the insert to achieve a smooth, optimal driving characteristics ensuring surface. Only in a subsequent operation is then the use under heating so permanently deformed that he then has the open to the bottom and the end of the sliding board body recess.

FR-A-2804612 shows a snow sliding board with a trough which is open at the top.

Representations similar to Figures 2 and 3, but before the deformation of the insert.

In the figures, 1 is a snow sliding board in the form of a snowboard. The snowboard body 2 has the usual structure and the usual shape, and in particular with a rear, scoop-like upwardly curved end or blade area 2.1 and a front, also scoop-like upwardly curved end or blade area 2.2.

Notwithstanding the usual embodiment of the snowboard 1 in the snowboard body 2 at the rear blade portion 2.1 an insert 3 is inserted, which consists of a permanently deformable material, i. in the illustrated embodiment consists of a thermoplastic polymer or polymer and in plan view of the snowboard 1 (Figure 1) is wedge-shaped or has the shape of a rounded V, in such a way that this, in the illustrated embodiment symmetrically to the Longitudinal axis L of the snowboard body 2 formed and arranged in the snowboard body 2 use in an axial direction perpendicular to the longitudinal axis L has a width which increases towards the free edge 2.1.1 of the rear blade portion 2.1 out.

The insert 3 has an upper side 3.1, a lower side 3.2 and an edge region 3.3 and also in the illustrated embodiment a material thickness that is equal to the material thickness of the snowboard body 2 in the region of the blade region 2.1. Furthermore, the insert 3 is formed so that it is at least with its bottom 3.1 is flush with the bottom 2.3 of the snowboard body, that merges flush into the bottom 2.3 of the snowboard body 2.

For receiving the insert 3, the snowboard body 2 is provided at its rear end or blade area 2.1 with a V-shaped recess 4 adapted to the shape of the insert 3.

Except for the edge region 3.3, where the insert 3 connects to the snowboard body 2 and is connected thereto, the insert 3 is arched, in such a way that it has a convex on the top 3.1 and a concave shape on the bottom 3.2 and thereby forms on the bottom 3.2 a recess 5, which may also be referred to as a trough or tunnel, the rear free and formed by the insert 3 edge 2.1.1 of the blade area 2.1 is also open and whose depth and width in the axial direction perpendicular to Remove longitudinal axis L with increasing distance from this free edge 2.1.1. The recess 5 is in the embodiment shown again symmetrical to the longitudinal axis L, has in plan view of the bottom 2.3 of the snowboard body 2 in the form of a rounded V and extends in the illustrated embodiment over all or a majority of the rear, upwardly curved blade area 2.1.

Just like the underside 2.3 of the snowboard body 2 forming the sliding surface, the underside 3.2 of the insert 3 is also machined, ie ground, to achieve the smoothest possible surface and thus to achieve the best possible gliding properties. In order to make this possible despite the shape of the insert 3, this insert is made in the illustrated embodiment of the thermoplastic material or polymer, and that according to Figures 4 and 5, initially without the tunnel or the recess 5 forming curvature, so that the insert 3 with its underside 3.2 forms the continuation of the adjacent underside 2.3 of the snowboard body 2, ie with this in the common, defined by the curved blade portion 2.1 curved plane and therefore the bottom 2.3 and the bottom 3.2 of the snowboard body 2 mounted insert. 3 worked together or sanded together can be. Only then is the insert 3 permanently deformed under heating into its curved shape.

In the illustrated embodiment, the insert 3 is made of a transparent, thermoplastic polymer or plastic.

Through the depression or recess 5, the flow of the snow or the gliding in the snow are advantageously influenced during snowboarding. This results u.a. an improved guide for the snowboard 1 especially in the powder snow as well as a reduced resistance in the rear blade area 2.1, so generally improved deep snow properties. Furthermore, the use of an improved spray is possible, d. H. an improved snow dust formation on the rear blade area 2.1 when driving in deep snow.

In the above, an insert 3 in V-shape provided in the snowboard body 2 has been described as an example. Of course, other forms are possible for use, such as the indicated in the figure 1 with broken lines in the blade area 2.2 disc-shaped insert 3 ', which is used in a closed edge forming recess in the snowboard body 2 and 2.2 in the blade area. Also, the insert 3 'is in turn concave on the underside of the snowboard body 2 to form a recess 5 corresponding recess and accordingly curved convexly on the upper side of the snowboard body. Of course, other forms for the respective use are possible, for example, strip-shaped inserts. Furthermore, it is also possible to provide several inserts at the respective end of the snowboard body 2. Furthermore, it is possible to form the respective insert 3 or 3 'in such a way that it is softer than the adjacent snowboard body.

The invention has been described above by means of exemplary embodiments. It is understood that numerous other changes and modifications are possible without thereby departing from the claims underlying the invention.

Thus, it is also possible, for example, to perform the insert 3 or 3 'in a multi-layered manner, for example to increase the strength and / or to adapt to different material requirements, for example on the top and bottom of the snowboard body 2 etc.
