Tracking device for ski trails

The innovation relates to a tracking device for pre-tracking for ski trails, drag lifts or the like. with a sliding surface and a connection device to a driving mechanism.

For grooming the fairway at ski trails or drag lifts So far, a heavier person has been used, the weight of which makes the skis buckled up pressed corresponding tracks into the snowpack.

But especially on cross-country trails, there is also a strong one and experienced cross-country skiers are hardly able to achieve the desired double track with the cross-country skis, which are anyway not resistant to pull flawlessly.

Of course, such pre-tracking is also extremely stressful, time-consuming and would also involve considerable costs cause. However, it is particularly disadvantageous that traces made in this way turn out to be very irregular and by the alternating loads on the ski also have a wavy shape, which is unfavorable for subsequent users of the trail is.

In the case of drag lifts, too, the tracks made by the skiers' skis are usually very irregular and, in particular, do not run parallel; this then often causes great difficulties, especially for children or inexperienced skiers, to stay in such tracks in order to avoid the otherwise hardly avoidable fall. Special devices for making tracks have therefore been created. A known device has runners or caterpillars or the like as track organs. on. Another Vorrichi ^Λ η§ shows a frame with runners on which a transverse to the direction of travel, connected to the frame cross bar for distributing and compacting snow and a height-adjustable pair of snow groomers attached to the frame or the cross bar is arranged. In front of it, a plurality of scraping elements protruding from the frame or from the transverse bar are arranged across the width of the frame for tearing up layers of ice or hard snow. The main disadvantage of this device is that the runners of the frame, in spite of the transverse strips provided on the frame, sink deeply into the fresh snow when the snow is thick. Furthermore, the tracks that can be created with the piste planer cannot be made cleanly, as the snow displaced by the piste planer partially falls back into the track behind them.

The known devices are particularly unsuitable in deep snow, since they, by making the tracks with the track organs in being pushed into the snow, too deep into the snow

sink. These deep tracks, which are disadvantageous in themselves, are also disadvantageous in that they sink in too deeply of the track-forming organs in the snow, this from the side walls of the track profiles partly back into the track ground falls back, which is particularly annoying on cross-country trails.

The task of the innovation is, while avoiding all the disadvantages described, with the help of a simple device in parallel tracks running towards each other at the top, reamed by the snow surface, remain constant, whereby the Tracks are cut out of the snow cover and the resulting snow is diverted next to the track formed will.

This is solved according to the invention in that the over the entire width of the device continuous sliding surface at the distance of one or more double tracks to be formed Has openings at the rear boundaries in the direction of movement of the device descending obliquely forward Clearance surfaces are connected, which lift the snow they have captured to the sliding surface on which to store the Snow deflecting surfaces are arranged next to the track path.

The inventive device has the advantage that in every type of snow and also in deep snow, exactly parallel Traces can be produced with constant equal depth. Sinking occurs due to the large sliding surface of the device Impossible in deep snow. If the deep snow is very soft, the snow can be compacted across the width of the sliding surface by loading weights onto the sliding surface will. Impeccable traces can be cut out of this compacted strip of snow with the new clearing surfaces will. With a very hard snow surface the weights serve to stabilize the sliding surface.

The räura surfaces are preferably at the rear boundaries the inclination angle of the openings can be changed, whereby the depth of the tracks is adjusted

can be.

The Räuinf can preferably smile in their length profile be concave.

In a further preferred embodiment, the clearing surfaces or their clearing edges can be exchangeable. this enables the use of clearing surfaces or clearing edges of different widths or different shapes.

In a preferred embodiment for the formation of tracks in cross-country skiing trails, the clearing edges are in their central area further forward in the clearing direction than in their side areas. The width of the middle area corresponds to approximately the width of cross-country skis and the entire width the clearing edge is slightly wider than a cross-country ski boot Such a track shape significantly improves the lateral guidance of the shot.

The innovation is explained in more detail below with reference to the figures of the drawing, without the description in the should be interpreted in a restrictive sense. Likewise, the reference signs cited in the following claims are intended mean no restriction; they only serve to make it easier to find related parts in the Figures of the drawing.

• In Fig. 1 of the drawing is an example of training of the tracking device shown graphically. It shows the tracking device in a version with a pair of clearing surfaces each, Openings and deflecting surfaces, FIG. 2 shows part of the sliding surface with an opening and a preferably clearing area.

The sliding surface 6 of the device is in the embodiment with a hitch 7 to a pulling mechanism, for example a vehicle, a slope grooming device or

Equipped on the rope of a drag lift. Instead ^ a hitch to a traction device also Anschießvorrichtung can be provided on a sliding vehicle.

To ensure that the device glides with as little resistance as possible to enable, the front end 4 of the sliding surface 6 provided with the hitch is similar to that of Skis bent up.

The sliding surface 6 is provided with openings 2 in the exemplary embodiment. To hers in the direction of pull rear boundaries 8 are connected to the sloping forwardly descending clearing surfaces 1 with their Front edges 9 capture the snow to be cleared and this during the forward movement of the device through the Lift the openings 2 upwards onto the sliding surface 6 and from there through the two of the sliding surface 6 upwards and backwards diverging Deflection surfaces 3 brought next to the track formed.

Between the backward diverging deflection surfaces 3, the sliding surface 6 offers sufficient space for a complainant standing on it or for a weighting weight.

On the surface between the bent end 4 and the openings 2 and / or between the weight weights 5 should be attached to deflecting surfaces diverging backwards. The straight lines in their longitudinal profile or concavely curved clearing surfaces 1 advantageously have an inclination of a maximum of 20 °. This angle of inclination can be variable with an articulated connection of the clearing surfaces 1 at the openings, so that the depth of the tracks is changed. The leading edges 9 of the clearing surfaces 1 kannπ be more or less sharp or designed with teeth in order to exert a kind of milling effect in hard snow can. To adapt to different types of snow you can
