DE3309177A1 - Covering for ski pistes or cross-country courses - Google Patents

Abstract

The ski-piste covering consists of strips of different surface structure on both sides. They are bonded to a base track at a distance from one another and transversely to the direction of travel. At the same time, the strips are bonded on alternatively with their rear side or with their upper side. A soft upper side affords good ski guidance, a hard rear side allows great speed. The strips can easily be replaced individually in the event of damage. Advantage: inexpensive manufacture and easy arrangement of the strips without removal of the base.

Patent application covering for ski slopes or cross-country trails The invention refers to a surface for ski slopes or cross-country trails made of flat areas - in particular Non-woven material.

The desire to go skiing even in the snow-free months. to be able to To take this into account, many attempts have been made, the most varied of which Results.

The requirements for such coverings are varied. Known rubbers generate too much friction when driving on. This in turn has - apart from other disadvantages - too high wear of the lining result. It is doubtful whether this frictional resistance allows rapid pacing or even swinging. One Another condition for such coverings that should not be underestimated is the possibility for good ski guidance, as given in gently yielding snow and for Swinging is absolutely necessary. These properties are common to known rubbers not to be found or only insufficiently.

It is also important that damaged areas in a surface can be easily repaired without having to replace a larger part of the covering, such as generally the production of the covering and its application on a suitable terrain must move within economic limits.

These conditions are met according to the invention in that the Covering as a strip at a distance from one another transversely to the direction of travel on a thin underlay attached iat.

The strips are optionally with their back or their top glued to the underlay.

An example according to the invention is illustrated by the drawing namely, Figure 1 shows a plan view of a number of underlay webs, in part with a strip covering and FIG. 2 shows a front view of the end of the underlay webs.

A strip 6 with a soft top layer 1 of a suitable non-woven material is with its compacted and therefore harder lower layer 2 on a Uhterlagbahn, in particular a weather-resistant film web 5 is glued on. At a distance of 3, which corresponds approximately to the width of the strip 6, another strip 6 is of this type glued on so that the harder lower layer 2 now faces upwards and the softer one Top layer 1 glued onto the film web 5 parallel to the previous strip is.

In this way of changing, the top cover glued on at a distance or underlayer of the strips 6 is. those with a number of film webs 5 occupied slope established. The butt joints 7 of the juxtaposed and butt against each other glued film webs 5 are also covered by an adhesive tape 4 on their underside locked.

The strips 6 with their soft top layer 1 allow the person to slide over them Skie a good guide, whereas the strips 6 with the harder, upwards side 2, which increases the speed of a ski gliding over it Effect shows Together with the distances 3 between the strips 6, one becomes special favorable ski guidance, especially when driving quickly due to less friction surface -achieved.

Type With this from applying a covering, it is also possible deliberately slowing down the journey in an irregular sequence of the stripe position 6, if for example, several strips 6 with side 1 up one after the other follow, or vice versa, speed up the journey when using multiple strips 6 follow page 2 to oban one after the other. However, this is only possible to a limited extent.

A strip 6 that has been damaged can easily be torn off and through a new strip 6 can be replaced without the entire film web 5 being lifted off must become.

These film webs 5 can be held on the slope by means of pegs if this requires a steeper terrain.

To reduce the friction between the ski and the slope surface, it is common to to provide the ski with a suitable lubricant.

You can do this at the end of a slope or at the end of a lift lane be provided with a lubricant soaked strip 6 through which at his Driving over the sliding layer on the ski is inevitably renewed. This comes especially then before when the softer layer is worn out, giving the benefit of a good one Ski guidance is no longer fully available. In this case you can also the loops of the fleece material open, creating friction on this part of the surface grows undesirably strongly.

The coverings produced in this way can also be used without any further difficulties used at ski jumps or when approaching water skiing.

Claims (5)

Claims 1.4 Surface for ski slopes or cross-country trails Area, in particular nonwoven material, characterized in that the covering is a strip (6) at a distance (3) from one another transversely to the direction of travel on a thin underlay (5) is attached. 2. Covering according to claim 1, characterized in that the strips (6) of the fleece material either with its back (2) or with its top (1) are glued to the underlay (5). 3. Covering according to claim 2, characterized in that the top (1) of the nonwoven material: softer than its rear side (2) is designed. 40 covering according to claim 3, characterized in that with strips occupied underlay sheets are joined together and the resulting butt joints (7) are closed on their underside with adhesive straps. 5. Covering according to claim 4, characterized in that one with a Strip soaked in lubricant at the end of a runway or at the end of one Lift lane for the inevitable renewal of a ski sliding surface is inserted.
