/ Track segment for artificial toboggan runs

The invention relates to a track segment for an artificial toboggan run which allows tobogganing that is independent of snow and ice possible in every season »

Carriages equipped with skids have been used for transporting people and / or people since prehistoric times Known loads on snowy or icy surfaces. People also liked it a long time ago found it, toboggan down steep slopes or the like with such sledges for pleasure. This out of this Tobogganing, a popular sport, was developed using blocks of snow and ice specially e built, winding tracks and steerable sledges for bobsleigh. Lately, tobogganing is also becoming more sporty Point of view in appropriate, from snow and ice built toboggan runs. Tobogganing and Bdteport are, however, pure winter sports, since they require a surface covered with snow or ice and those during the during the cold season, the tracks built in the spring merge.

With the increasing proportion of leisure time, there is now a strong need for it, which was originally only in the cold season practicing winter sports all year round. For this purpose, on the one hand, they were also usable in summer Artificial ice rinks and, on the other hand, for example, a dry ski slope provided with brush slopes. Of the Thought of using chillers year round

Creating usable artificial ice toboggan and bobsleigh runs has proven to be impossible for technical and economic reasons proved to be feasible, since such paths must have the opposite Skate tracks only -by relatively few people be used at the same time know the maintenance of the environment the necessary, strong screens in the warm season requires an unacceptably high level of effort and the surface of the track surfaces becomes dull due to the sun's rays is made so that perfect driving conditions cannot be achieved «Bio in the construction of Trookenski facilities The floor coverings used cannot be used for toboggan runs and bobsled runs because of the long runways and the high speeds that occur, excessive heating due to frictional heat would occur

The object of the invention is now to provide orbit segments for artificial To create toboggan runs of the type mentioned, which avoid the previous disadvantages and with simple Knowing how to use means without costly artificial ice production even in the warm season

To solve this problem, the track segment of the type mentioned is characterized according to the invention by a Trough-like, concave, grooved shape and a sliding layer made of polymethylene oxide or arranged on the inner surface fluorine-containing polyalkylenes, especially polytetrafluoroethylene, or stainless steel

According to a preferred Aueführungsform the sliding layer is made at the edge regions of the web segment detachably mounted, adjacent clamped on the grooved inner surface of liner made of polytetrafluoroethylene or polymethylene · In this case, the sliding film zweokmässig respectively in Bahnriehtung the Stirakanten ά · τ web se entente wrapped and the outer side detachably attached · The attachment of the liner to the side edges of the

Track segments are advantageously made by means of detachably attached holding fixtures,

According to another embodiment, the sliding film can also consist of stainless steel sheet, which is attached at least to the side edges and the front and bottom of the track segment is «the sheet steel can be used in these areas, but optionally also in the area of the grooved inner surface with the track segment by welding, in particular Point to be connected · Depending on the dimensions and the requirements, the railway segments know but also essentially consist entirely of stainless steel

For the rapid drainage of low-level water, the track segments are expediently joined together, leaving narrow transverse joints free. Bio groove of the inner surface of the track segments corresponds in cross section preferably to an arc of 60 to 180 ° with a radius of 60 to 120 cm or a sllipsenbogen with an essentially lying major axis of 12Θ to 300 cm and a minor axis of k @ to 12Θ cm. Bio-curves of the path are advantageously composed of path segments that are straight in the direction of the path and are of sufficiently short length, each of which has at least one end edge that runs obliquely to the path and a curve extension and inclination sufficient to overlap the outside.

The following are preferred embodiments of the invention explained with reference to the accompanying drawings. Point sa

Flg. 1 shows a schematic cross section through a completely installed Rail segment and

Fig. 2 shows a similar longitudinal section through the kneading two neighboring ban segments

The illustrated in Figure 1, ie cross-section a circular arc sound about 18C Mitsprechende web segment 1 is fixed in accordance with ■ an arrangement in a curve of the toboggan run in a sufficient to Aussenüberhuhung inclination -from about kO ° at the Tragsehale 14 of a Y-fureigen carrier 13, which is releasably fastened by retaining nuts 12 to cast-in threaded bolts of a concrete foundation 10 arranged ie underground. The carrier 13 and the supporting shell \ k are in the ground in such a way that the track segment 1 is somewhat embedded in the ground, but both side edges 6 are above the ground. To absorb the side loads occurring in the curves, lateral support shells 15 supported in the ground are expediently provided. The railway segment 1 itself can be made of metal, plastic, wood, concrete or other mineral building materials, depending on the requirements, the material properties and dimensions having to be matched to the expected loads, taking into account sufficient safety factors.

A 2 mm thick sliding sheet 2 made of polytetrafluoroethylene is clamped onto the groove-like fluted inner surface of the track segment 1 by means of retaining strips 3 fastened to the side edges 6 by screws h under their inherent rigidity against the inner surface of the track segment 1. In the embodiment shown in FIG. 2, the sliding film 2 is placed around the end edges 8 of the track segments 1 and is also fixed in their outer edge regions by means of screws 3 and retaining strips h.

In order to carry away the rainwater that gets into the railway, the railway segments 1 are in each case released narrow transverse joints 5 joined together. In the curves of the path, there are preferably also straight lines in the direction of the path Track segments 1 with diagonally to the track direction

running front edges and sufficiently short length used. The one required on the respective outside of the curve Elevation of the side edges in the direction of the circular arc should rise and fall continuously in two dimensions · This can be achieved by a correspondingly beveled cut of the upper side edge 6. If laying around the Sliding film 2 around the front edges 8 dor grooved track segments with high Eigensteifigkelt leads to difficulties Longitudinal cuts can be made in the areas below the inner surfaces touched by the carriages.

If a stainless steel sheet is used instead of a sliding film made of polytetrafluoroethylene »and the track segment 1 is also made of metal, the sheet steel can be on the side edges 6 and the front edges 8 directly be blackened with the track segment 1. In addition, the sheet steel can be used to the extent that it is appropriate according to the requirements also be blackened or glued to the inner surface of the web segment in suitable areas.

The use of a relatively thin sliding film 2 has the advantage that this, after sufficient wear and tear, is applied to the The respective track segments affected can be exchanged quickly and easily.

The polytetrafluoroethylene sliding films preferred according to the invention They not only have a particularly low coefficient of friction, but are also abrasion-resistant, non-swelling and resistant to high and low temperatures as well as ozone and UV radiation.

In principle, it would also be possible to use track segments with a coating that is firmly applied to the inner surface made of polytetrafluoroethylene to be used. With the dimensions of the track segments and the very
