SLIDING ELEMENT FOR SUMMER USE OF JUMPING MOUNTAINS - GLIDELE-MENT FOR HOPPBACKAR VID SOMMARBRUK

The present invention relates to a sliding element for summer use on hills, for example jumping hills, which element comprises a plastic mat formed of one or more overlapping plastic fiber layers fastened together at one end by means of a base.

Such sliding elements are most commonly used on the descent slopes of jumping hills and at the edges of an uphill runway. The sliding elements, which are relatively small in size, are arranged side by side and in succession so that the base parts are covered, thus creating a uniform plastic mat. The sliding properties of the plastic mat correspond very well to the properties of the snow, which is important so that jumps can be made from the jumping hill in the summer to suit winter conditions. The training of the best jumpers in particular today is so full-fledged and year-round that it must be possible to jump in the summer as well.

The sliding elements are attached to a metal net mounted on a slope, which is thus immediately below the plastic mat. The disadvantage of this construction is that the slip-deteriorating undergrowth tends to grow through the plastic mat, because the plastic mat consists only of yarn-like plastic fibers. There is also a danger that when the jumper falls, the fibers will turn and the jumper will injure the me ta11ive network that is revealed from below.

The object of the present invention is to provide a sliding element which does not have the above-mentioned problems. The invention is thus characterized in that under the plastic mat, a uniform base plate formed of separate strips and having a substantially sliding element in area is attached to the same base part.

A preferred embodiment of the invention is characterized in that the base plate is corrugated transversely or longitudinally or otherwise shaped to provide flexibility. Previously, elasticity was achieved by adding a layer of foam sheet below the metal mesh.

Another preferred embodiment of the invention is characterized in that the base plate is made of plastic or a similar material.

The most important advantage of the invention is that the base plate effectively covers the metal mesh, so that it does not appear even in the event of a fall. Undergrowth cannot grow through the base plate either.

In the following, the invention will be explained in detail by way of example with reference to the accompanying drawing, in which

Fig. 1 shows a sliding element according to the invention seen from the side.

Fig. 2 shows a sliding element seen from above.

Fig. 3 shows the installation of the sliding elements on the slope.

Figure 1 is a side view of a sliding element according to the invention. The sliding element consists of plastic fiber layers 3 and a base plate 2 arranged below them, which is most preferably made of plastic. The total thickness of the plastic fiber layers is about 1 cm. The base plate may be a unitary entire element-sized plate or may be formed of separate strips of plastic consisting of a substantially element-sized plate. The base plate is made with a corrugated profile to make the structure flexible. The thickness of the base plate is approx. 0.3 - 3 mm.

The plastic fibers 3 are fused together at one end and together with the base plate 2 are then mounted on a v-shaped base 1 which is fastened with rivets 4. The wire-like plastic fibers are made slightly wavy in shape to reduce friction between the ski and the fibers.

The installation of the sliding elements is otherwise carried out in the same way as before, i.e. it is attached to the base metal network 5, as shown in Fig. 3. It can also be seen from Figure 3 that the base plate 2 is at all points between the metal mesh 5 and the plastic fiber layers 3.

It will be clear to a person skilled in the art that the invention is not limited to the above exemplary embodiment, but can be varied within the scope of the appended claims. Thus, for example, in order to provide flexibility, the base plate does not have to be corrugated in the longitudinal direction shown in the figures, but an equally good result is also obtained by corrugating the base plate transversely.
