Definitions

  • the above invention relates to a device for generating. a cross-country ski run.
  • the runners provided in the known devices are fixed and there is no possibility of bringing these runners out of contact with the snow field.
  • This has the serious disadvantage that the sensitive running surfaces of the runners are damaged if e.g. a field that is not covered with snow is to be crossed, e.g. B. roads, paths or rock fields.
  • a further device for creating cross-country ski trails which consists of two articulated sledges, the first sled used to roughen and loosen up the often heaped snow field, and the second sled has fixedly arranged skids.
  • the slide with the skids always remains in contact with the snow field and therefore the disadvantages already explained also occur with this device.
  • the object of the above invention is to propose a device for creating a cross-country ski run which, for. B. can be pulled by a piste preparation machine or a similar traction device, and with which equipment the known Devices of this type inherent disadvantages can be avoided with certainty, and the creation of perfect cross-country trails possible. It is also the task of the object of the invention to propose a device for creating cross-country trails with which it is possible to automatically and quickly bring the runners for making the cross-country trails out of contact with the snow field, or to automatically and quickly move the runners into the desired working position move.
  • openings are provided in a plane of the pullable sled which is arranged parallel to the snow field and to which parallel receiving means are assigned which have runners on at least one side for creating a cross-country ski run, that these receiving means are rotatably mounted, in order to be able to be brought from a working position in which the runners for creating the cross-country ski run protrude from the underside of the sled surface into a rest position in which the runners are not in contact with the snow field, and furthermore the longitudinal openings of the sled are closed by corresponding end surfaces of the receiving means are.
  • the device according to the invention consists of a slide 1 which is designed as a flat plate which has a slightly curved wall 2 on its front side. With the wall 2, a drawbar 4 is connected via joints 3, which is connected to the tractor, advantageously a piste preparation device or another snow vehicle.
  • Openings 6 are incorporated into the plate 5 of the carriage 1, which are arranged parallel to one another and extend in the longitudinal direction of the device, in the forward movement shown by the arrow f.
  • pivot bearings 8 are advantageously provided on the plate 5, which receive holding and receiving devices 9 which can be rotated about their longitudinal axis.
  • the holding and receiving devices 9, which can have any suitable shape, advantageously have a triangular cross section, and are particularly designed as a triangle with at least two identical sides.
  • the surfaces of the receiving and holding means 9 assigned to the same sides have approximately the dimensions of the openings 6 of the plate 5 of the slide 1.
  • the holding and receiving means 9 have protruding tabs 10, with which brackets 11 are operatively connected via suitable joints, one of which is operatively connected to the rod 12 and the other to the cylinder jacket 13 of a hydraulic cylinder.
  • the cylinder unit is controlled in an advantageous manner via pressure fluid, which, for. B. are supplied via pressure lines 14 from the central hydraulic unit of the tractor.
  • pressure fluid which, for. B. are supplied via pressure lines 14 from the central hydraulic unit of the tractor.
  • a pneumatic or electrical control can also be used.
  • a protective frame 15 is arranged above the rotatable holding and receiving means 9, in the middle of which a small column 16 protrudes upward from the plate 5 of the carriage 2. If necessary, a weight, not shown, can be placed on the protective frame 15 and the column 16, for example in the form be arranged in a concrete block.
  • the device according to the invention is shown schematically in the working position.
  • the hydraulic cylinder 13 is acted upon by the pressure medium in such a way that the piston rod 12 is extended out of the cylinder 13.
  • the runners are arranged in their working position and therefore, during the movement of the slide in the direction of the arrow f, shape the desired depressions of the cross-country ski trail. 19 in the snow field.
  • the rest position of the runners 17 is shown in FIG. 3.
  • the carriage 1 In the position shown in FIG. 3, the carriage 1 has a straight line and the underside which is not interrupted by openings;
  • the runners 17 for creating the cross-country ski trail are not in the working position, but in their rest position, in which the runners 17 are protected from damage by roads, paths or rocky areas not covered with snow.
  • the rotation of the runners 17 in the working position (Fi g . 2) or in the rest position (Fig. 3) can be controlled automatically, for example, from the driver's cabin of the piste preparation device or the snow vehicle, for this purpose it is sufficient to provide a suitable control lever in the driver's cabin in order to convey the pressure medium via the pressure lines 14 to the cylinder 13 in the desired manner.
  • Piston-cylinder units 12, 13 are only operatively connected to the rotatably arranged holding and receiving means 9.
  • no further storage and holding means for receiving the piston-cylinder unit 12, 13 are to be attached to the surface 5 of the slide 1.
  • This embodiment enables the piston-cylinder unit 12, 13 to be designed to be particularly functional and simple in terms of its mechanical complexity.
  • Pivots 9a protrude from the ends of the holding and receiving means 9, which are received by suitable bearings 8, which are fixedly arranged on the surface of the carriage 1, with particular advantage. 4, the skids 17 for creating the cross-country ski trail are in their working position. 4 that the surface of each holding and receiving means corresponds essentially to the shape and the dimensions of the corresponding openings 6. 4 also shows the piston-cylinder unit 12, 13 which essentially consists of the cylinder 13 and the displaceable piston and the associated piston rod 12. Both the cylinder 13 and the piston rod 12 are articulated with the holding and receiving means 9 using tabs and brackets, marked with 10 and 11 connected. 4 that the cylinder 13 is acted upon by the pressure medium via pressure lines 14.
  • FIG. 5 and 6 show a further advantageous embodiment of the device according to the invention for creating cross-country ski runs.
  • This modified embodiment also consists of a flat slide, which is also provided with openings 6 through which the runners 17 can emerge to create the cross-country ski run.
  • the runners 17 are essentially supported by a cylinder 30, at the ends of which the runners 17 are arranged.
  • the cylinder 30 receives two pistons in its interior, which can be controlled independently of one another, and whose rods 31 and 32 emerge from the cylinder 30 at the ends thereof.
  • the rods 31 and 32 are operatively connected to the surface 5 of the carriage 1 via joints 33 and 34 and via levers 35 and 36, the free ends 37 and 38 of which are formed as joints.
  • 5 bellows 39 or similar protective and covering means are advantageously provided between the top of the runners 17 and the slide surface 5 in order to prevent snow 6 from penetrating through the openings and being able to settle on level 5 of the slide 1. If the rods 31 and 32 are withdrawn as far as possible into the cylinder 30, the corresponding runners 17 for creating the cross-country ski run are opened through the openings 6 Level 5 of the slide 1 is pressed in order to move into its working position, as shown in FIG. 5.
  • the traces 19 must of Langlaufloi p e, for example to cross a designated S road or a path.
  • the holding and receiving means 9 are actuated before reaching the street S 'and by rotating the holding means 9 about its longitudinal axis it is achieved that the street S is then crossed by the carriage 1 when the runners 17 are in their protected rest position.
  • the hydraulic device is actuated again and, by a new rotary movement about its longitudinal axis, the skids 17 are again brought into their working position for creating the cross-country ski run.
  • Fig. 9 shows that numerous parallel starting trails can be created at the launch site, which are gradually interrupted after the start and invite the cross-country skier to do so, only on one of the two centrally located trails Cross-country trails that extend across the entire trail continue.
