Definitions

  • the invention relates to a run-in track for ski jumps.
  • Such start-up tracks regularly provide a pair of ruts, so that for each jump of the Skispringers a rut is present.
  • start-up tracks in which the two ruts in a continuous, formed on the ski surface snow or ice cover formed are. Furthermore, from the German utility model 200 11 567 a starting track known at the bottom of the ruts of metallic sliding track shingles is formed. The surface design and coating of the sliding track shingles allows the ski jumpers to slide down the inrun track similar to snow.
  • DE 198 43 901 C2 It is also known from DE 198 43 901 C2 a method for preservation of snow and a cooling mat device for carrying out this method. Method and device are used for the preservation of snow on mountain slopes and ski slopes.
  • DE 196 38 714 A1 discloses a mat-like heat exchanger for cooling and / or heating purposes. From CH 174 772 and CH 174 551 Freezers for artificial ice rinks are known.
  • the inventive inrun track over a longer period authentic and consistent starting conditions on snow or ice cream.
  • the influence of weather on the Snow or ice conditions in the inrun track are restricted.
  • the inrun track of the invention easily and inexpensively manufactured and can be operated.
  • the inrun track comprises a cooling start track with at least two substantially vertical side walls.
  • the cooling start track for example, by a horizontally extending Floor closed, it is open at the top.
  • the cooling start track may be due to her box or trough-shaped profile with snow, with natural snow or with artificial snow or a mixture of both.
  • a cooling device is provided, with which the cooling starting track can be cooled to preserve the snow in it.
  • the cooling device For example, by a flowed through by a coolant Tube plant can be realized.

  • the desired advantages are achieved.
  • the cooling The snow or ice conditions in the cooling start-up track can change even when changing Weather conditions over a comparatively long period kept costly become. Since only the preferably approximately 45 cm wide cooling track are cooled must, is to be cooled snow or ice and thus the cooling effort comparatively low. This allows the constant conditions comparatively produce economically.
  • the invention thus provides independence from the weather and thus from competition organizers Desired high event security.
  • an alternative start-up track is in addition to the cooling start-up track provided, which is usable without snow or ice pad. Reached This is because the inrun track has a sliding surface.
  • the sliding surface may have a knobbed structure.
  • a sliding material can be made of metal and / or ceramic and / or glass and / or other suitable materials. By this sliding surface is made possible that the ski jumpers in the alternative start-up track without snow cover but similar to snow on the inrun track can slide down.
  • the combination of a cooling starting track with an alternative starting track allows a multifunctional use in all weather conditions and in the different seasons.
  • the cooling starting track is made of a pair formed by parallel adjacent cooling grooves.
  • Each of the two Cooling gutters has two side walls, which together with the intermediate Ground the upwardly open cooling gutters a total substantially Give U-shaped cross-section. Due to their box profile, the Cooling ruts with snow, with natural snow or with artificial snow or be filled with a mixture of both. In this embodiment, it is enough to cool only the cooling ruts, whereby the snow to be cooled or Ice quantity is further reduced.
  • the cooling takes place at the bottom of the cooling grooves, in particular characterized in that the bottom of the cooling grooves designed as a cooling floor is, which is flowed through by a coolant.
  • the cooling takes place on the side walls of the cooling ruts, wherein the Walls may be configured as cooling walls, which flows through a coolant become.
  • the cooling can be done both on the floor and on the walls the cooling grooves are made, in particular in that a cooling floor and Cooling walls are provided, which are flowed through by a coolant.
  • the width of the cooling grooves is selected to be the width a jump over something.
  • the jump ki can on the one hand with lateral Game are absorbed in thedespurrinne, on the other hand, by the limitation of the width of the cooling grooves reduces the required amount of snow.
  • Particularly suitable is a width of the cooling grooves of 13.5 cm.
  • the distance between the center axes of the cooling grooves becomes so chosen to be approximately the distance of the skydive during startup on the Jump corresponds.
  • Most suitable is the usual in ski jumping competitions Distance of 32 cm.
  • the required snow ski for the ski jumping is to the required minimum width, namely the width of two jump skis plus reduced some lateral play. This will set the required amount of snow reduced and the cooling effort is minimized.
  • the alternative starting track consists of a A pair of alternative ruts running parallel to each other, their bottoms designed as a sliding surface.
  • the start parabola determines the geometric characteristics of the Starting. For an unmodified starting parabola, therefore, cooling start track and Alternativanlaufspur be arranged relative to each other so that the snow surface in the cooling track in filled condition at the same height as the ground the alternative start-up track.
  • cooling start-up track and alternative start-up track are intertwined are arranged offset, i. if the two types of ruts, sodespurrinnen and Alternativspurrinnen, are arranged alternately, so that in Gap between the two cooling grooves an alternative rut to lie and in the space between the two alternative ruts one Cool rut.
  • the total width of the inrun track can be kept low be so that the additional run-in track only to widen the width of a Ride leads.
  • the consisting of cooling start-up track and alternative start-up track Inrun track designed as a module, in the surface of the Schanzendeckplatte can be admitted. If the inrun track sunk so far that its top edge flush with the surface of the Schanzendeckplatte, so you can Cover the inrun track with a cover and get a flat ramp face. This flat surface can be covered with snow, so that the jump can also be used in a conventional manner, that is through complete coverage of the ski-jump surface with natural and / or artificial snow and formation of the inrun track in the closed snowpack. In this way allows the inrun track according to the invention a multi-functional use of Ski jumping facility.
