The invention will be explained in more detail below with reference to the figures of an embodiment. Show it:

Fig. 1

in simplified representation and in plan view of a snow sliding board in the form of a ski;

Fig. 2

a section corresponding to the line I - I of FIG. 1 and

Fig. 3

a section corresponding to the line II - II of FIG. 1 ,

For ease of explanation, three mutually perpendicular spatial axes are indicated in the figures with X, Y and Z, of which the X-axis is the longitudinal axis L of the ski body and of which the Y-axis of the width B and the Z-axis of the height of the ski body 2 correspond.

The ski generally referred to as 1 in the figures, or its ski body 2, is made, for example, using conventional skiboot materials, with a front rounded and scoop-like upward, i.e., upwards. on the upper side of the ski body concavely arched ski body end 2.1 and with a rearward also rounded and scoop-like upward, i. on the upper side of the ski body concavely arched ski body 2.2, with a central binding and ski body 2.3 for attachment of a binding or binding plate, not shown, with adjoining the ski body area 2.3 ski body areas 2.4 and formed with these subsequent Skikörperbereichen 2.5, at the front or rear end of the ski body 2.1 or 2.2 end.

A special feature of the ski 1 is that the ski body 2 over its entire length perpendicular to the ski body longitudinal axis L and X-axis has an increased width B, for example, a width greater than 100 mm, with a reduced weight of the ski body 2, so that the ski 1 is suitable as a freestyle ski as well as touring skis in particular also for driving in deep snow.

In detail, the ski body 2 on its underside extending over the entire width B running or sliding surface 3, which consists in a known manner from the Gleitflächenbelag 4 and the two, along the longitudinal sides of the ski body 2 extending steel edges 5.

Component of the ski body 2 is furthermore the core 6, which is made of, for example, wood and / or another material suitable as a ski body core, for example of foamed plastic, e.g. Plastic foam exists and extends over the entire length of the ski body 2 from the front end of the ski body 2.1 to the rear ski body end 2.2.

Again FIG. 2 can be seen, in the middle ski body area 2.3 of the core 6 is laterally provided with a side cheek 7, which is supported with its arranged in the XY plane underside directly or indirectly to the relevant steel edge 5 and at least at this the respective steel edge 5 adjacent bottom in the direction of the Y-axis has a cross-sectional width which is equal to the local width of the steel edge 5 and which in any case is greater than 50% of the cross-sectional dimension which the side cheek 7 has on its core 6 adjacent surface in the Z-axis direction , The side wall 7 are made of a suitable plastic.

Between the Gleitflächenbelag 4 and the core 6, a lower flange 8 is arranged, which extends over the entire length of the ski body 2 between the steel edges 5 and is formed in the illustrated embodiment of a carbon fiber reinforced layer or layer of plastic.

The upper side of the ski body 1 is formed by a reinforced by carbon fibers layer or shell 9 made of plastic, which extends over the entire width B and length of the ski body 2 and in the embodiment shown at the same time also necessary for the stability of the ski body 2 upper chord forms. Under the shell 9 and also partially between this and the core 6, a reinforcing layer 10 made of carbon fibers and plastic is further provided, which is connected flat with the shell 9, also extending over the entire width B and length of the ski body 2 and in the illustrated embodiment, where the core 6 is present, immediately adjacent to the top of the core 6.

In the middle ski body region 2.3, the width B of the ski body 2 is determined by the distance that the two side cheeks 7 exposed there on the longitudinal sides of the ski body 2 have in the Y axis from one another. Furthermore, shell 9 as well as the reinforcing intermediate layer 10 end in the middle ski body region 2.3 respectively at the top of the relevant Side cheek 7 and are connected there in a suitable manner with the side wall 7. Furthermore, in the middle ski body region 2.3, the cross section and in particular also the width B of the ski body 2 are essentially determined by the cross section of the core 6.

In the illustrated embodiment, the core 6 is shaped on its upper side facing the upper side of the ski so that the cross-sectional dimension of the core 6 in the Z-axis initially increases, starting from that of a side wall 7, then over the vast majority of the width of the ski body 2 is constant or substantially constant and to the other side cheek 7 decreases again accordingly. Furthermore, the ski body 2 is formed in terms of its cross section and in terms of the components used and their arrangement mirror-symmetrical to a arranged in the XZ plane and the longitudinal axis L enclosing center plane M.

The FIG. 3 shows the cross section of the ski body 2 at the ski body areas 2.5. There, the width B of the ski body 2 is not determined by the width of the core 6, but the core has a relation to the ski body width B significantly reduced width in the direction of the Y-axis, ie the width of the core 6 is outside the binding area significantly less than 50% of the ski body width B, for example 40% - 50% of the ski body width B. Like the FIG. 3 The shell 9 as well as the reinforcing intermediate layer 10 are here guided over the extending in the direction of the X-axis longitudinal sides of the core 6 and laterally from this with the lower flange 8 and the Sliding layer 4 is connected flat to a multilayer laminate structure. In still mirror-symmetrical to the median plane M executed cross-section, the ski body 2 at the ski body areas 2.5, ie between the areas 2.4 and the front and rear end of the ski body 2.1 or 2.2 at its top in each case one substantially formed by the core 6 raised portion 11 with the width b, to which in the direction of the Y-axis to the two longitudinal sides of the ski body 2 towards each a wing-like portion 12 connects, which does not have the core 6 and whose width in the direction of the Y-axis, for example, 70% - 80% of the corresponding Width of the core 6 and the width b and the total thickness in the Z-axis direction by a factor of two to three is greater than the maximum dimension, the steel edges 5 have in the Z-axis direction. The sections 12 are essentially formed by the laminate structure of the shell 9, of the intermediate layer 10, of the lower flange 8 and of the sliding lining 4. Furthermore, in the illustrated embodiment, the sections 12 each have a constant or essentially constant thickness in the direction of the Z-axis over their entire width oriented in the direction of the Y-axis as well as over the entire length oriented in the direction of the X-axis.

Again FIG. 3 can be seen further, the core 6 is shaped so that the ski body 2 at the ski body areas 2.5 even at section 11 in the direction of the Z-axis has a thickness which is smaller than the corresponding thickness in the ski body area 2.3 or binding area, ie at In the illustrated embodiment, the corresponding thickness of the ski body 2 outside the ski body area is only about 70 to 85 of the thickness in the binding area.

The described design of the ski body 2 results in a large ski body width B, a substantial reduction of the total weight of the ski body 2, wherein the ski body 2 in terms of torsional stiffness and flexural rigidity, also with respect to bending or flexing about axes parallel to the Y-axis, as well as in terms its mechanical strength not only corresponds to a ski body which is very narrow in the ski body area 2.3 or in the binding area and the ski body areas 2.5 corresponding to the section 11, but also the wing-like portions 12 contribute to the torsional stiffness and bending stiffness and create the for the Driving necessary ski body width B especially in deep snow.

The two ski body regions 2.4, which directly adjoin the middle ski body region 2.3, respectively form transition regions to the ski body regions 2.5, i. At the ski body areas 2.4, the sections 12 are increasingly formed, or vice versa, the width b of the raised section 11 is reduced steadily there from the width B in the ski body area 2.3 to the width b at the ski body areas 2.5.

In the illustrated embodiment, the ski body area 2.3 together with the ski body areas 2.4 occupies about 30% to 40%, preferably about 35%, of the total length of the ski body 2. The ski body region 2.5 extending to the front ski body end 2.1 has a length which corresponds to approximately 35% to 45%, preferably approximately 40%, of the total length of the ski body 2. The ski body region 2.5 extending to the rear ski body end 2.2 has a length which corresponds to approximately 20% to 30%, preferably approximately 24% of the total length of the ski body 2.

The ski body 2 has on its longitudinal sides a certain sidecut, in the form that the width B in the middle of the ski body 2 is smaller than the two ski body ends 2.1 and 2.2. Furthermore, the width b of the raised region 11 in the longitudinal direction of the body also changes to a certain extent, and the height or the thickness that the raised region 11 has in the Z-axis direction increases from the respective ski body region 2.4 to the front or rear. rear end of the ski body 2.1 or 2.2 towards.

Table I below shows the progression of the widths B and b as a function of the distance X (distance location) from the rear end of the ski body 2.2. The distance X is in each case given as a percentage relative to the total length of the ski body 2, the width B as a percentage of the maximum width B, the ski body 2 at its front ski body end 2.1 or at the local blade area, and the width b in terms of percentage the width B, which has the ski body at the respective Abstandsort. Table I Distance X as a percentage Width B related to maximum width B Width b based on width B X1 5% about 92% about 40% X2 24% about 82% about 48% X3 29% about 78% about 100% X4 54% about 78% about 100% X5 59.5% about 81% about 48% X6 93% about 100% about 40%

In the following Table II, the course of the widths B and b are again given in units for a ski body whose length corresponds to 1823 units, one unit being preferably one centimeter. Table II Distance X Width B Width b X1 91 units ca.132 units about 52.8 units X2 434 units ca.117 units about 56.2 units X3 522 units about 1212 units about 1212 units X4 997 units 112 units 112 units X5 1084 units ca.116 units about 55.7 units X6 1695 units about 143 units about 57.2 units

The invention has been described above by means of an embodiment. It is understood that numerous changes and modifications are possible without thereby departing from the inventive concept underlying the invention. For example, to achieve certain mechanical and / or dynamic properties of the ski body 2, it is possible to integrate further elements or components in the latter, for example to surround the core 6 with a torsion box formed from a fiber-reinforced plastic material and / or additionally to cover the upper shell 9 to provide an outer decorative layer and / or, for example, perform the intermediate layer 10 at least in sections multi-layered.
