Definitions

  • the invention relates to a run-in track for ski jumps.
  • Such start-up tracks regularly provide a pair of ruts, so that there is a rut for each jump skier of the ski jumper.
  • start-up tracks in which the two ruts are formed in a continuous, located on the ski surface snow or ice cover.
  • a run-in track is known in which the bottom of the ruts is formed of metallic Gleitspurschindeln.
  • the surface design and coating of the slip track shingles allows the ski jumpers to slide down the run-in track similar to snow.
  • the previously known tarnishing tracks for ski jumping hills have the disadvantage that they can only be used to a limited extent.
  • the molded into the closed snow blanket track first assumes that sufficient amounts of snow are available. If the jump is not covered by sufficient natural snow due to unfavorable weather conditions, natural snow and / or artificial snow must be brought in with considerable effort and applied to the jump. In unfavorable, especially changing weather conditions, the snowpack on the ski jump is also very limited shelf life. Even in the winter months, the temperatures in the vicinity of the mostly located in the valleys ski jumping hills partly clear and for longer duration above freezing. Permanently constant snow or ice conditions can therefore not be provided regularly on the previously known ski jumps even over the winter months.
  • the snow-free inrun track known from German Utility Model 200 11 567 can not be used for official competitions since the competition conditions require a start on snow or ice.
  • the snowless inrun track can therefore only be used for training purposes.
  • ski track element which comprises cooling pipes for cooling the ski track.
  • the inrun track according to the invention should ensure authentic and as constant as possible start-up conditions on snow or ice over a longer period of time. Above all, the influence of the weather on the snow or ice conditions in the inrun track should be limited. Furthermore, the inrun track according to the invention should be easy and inexpensive to manufacture and operate.
  • the inrun track according to the invention comprises a cooling starting track with at least two substantially vertical side walls. Down the cooling track is, for example, by a horizontally extending Floor closed, it is open at the top. Due to its box or trough-shaped profile, the cooling starting track can be filled with snow, with natural snow or artificial snow, or with a mixture of both. Furthermore, a cooling device according to the invention is provided with which the cooling starting track can be cooled to maintain the snow in it.
  • the cooling device can be realized, for example, by a pipe system through which a coolant flows.
  • an alternative starting track is provided, which can be used without snow or ice support.
  • the sliding surface may have a knobbed structure.
  • the sliding material may consist of metal and / or ceramic and / or glass and / or other suitable materials.
  • the height of the sidewalls i. the depth of the cooling starting track is selected so that a snow depth up to 25 cm can be achieved in the cooling intake lane.
  • the transverse webs can be part of the cooling device at the same time.
  • the width of the cooling track should be chosen so that it does not significantly exceed the width required for two ruts. For a regular width of about 45 cm will be sufficient.
  • the cooling track can be additionally isolated to reduce the cooling effort.
  • the desired advantages are achieved.
  • cooling the snow or ice conditions in the cooling intake lane can be kept costly even in changing weather conditions over a relatively long period. Since only the preferably approximately 45 cm wide cooling track must be cooled, the snow or ice to be cooled and thus thedeauf wall is comparatively low. Thus, the constant conditions can be produced relatively inexpensively.
  • the invention provides in this way independence from the weather and thus the desired by event organizers high security event.
  • the sliding surface makes it possible for the ski jumpers in the alternative starting track without snow cover to slide down the inrun track in a similar way to snow.
  • the combination of a cooling starting track with an alternative starting track allows a multi-functional use in all weather conditions and in different seasons. In the winter season (November to March), due to the lower average temperatures, the snow or the ice in the cooling track can be obtained so that the cooling track can be used continuously even in the case of weather fluctuations. In the warm summer season, the alternative track can be used for training purposes. Thus, the same ski jump can be used year-round for ski jumping. In particular, a change from winter to summer operation is possible without structural changes.
  • the cooling inrun track is formed from a pair of cooling ruts running parallel next to one another.
  • Each of the two cooling grooves has two side walls which, together with the base therebetween, give the cooling grooves, which are open at the top, a generally U-shaped cross-section. Due to their box profile, the cooling ruts can be filled with snow, with natural snow or artificial snow, or with a mixture of both. In this embodiment, it is sufficient to cool only the cooling ruts, whereby the amount of snow or ice to be cooled is further reduced.
  • the cooling takes place at the bottom of the cooling grooves, in particular in that the bottom of the cooling grooves is configured as a cooling base, which is flowed through by a coolant.
  • the cooling takes place on the side walls of the cooling grooves, wherein the walls can be configured as cooling walls, which are flowed through by a coolant.
  • the cooling can be done both on the ground and on the walls of the cooling grooves, in particular by the fact that a cooling bottom and cooling walls are provided, which are flowed through by a coolant. By the cooling only on the ground, the cooling costs can be reduced. By cooling on the ground and on the side walls, the snow metamorphosis can be delayed from snow to ice, so that the snow conditions remain constant over a longer period.
  • the width of the cooling grooves is chosen so that it slightly exceeds the width of a jump skis. This allows the jump skis to be received on the one hand with lateral play in the cooling raceway, on the other hand, the required amount of snow is reduced by limiting the width of the cooling ruts.
  • Particularly suitable is a width of the cooling grooves of 13.5 cm.
  • the distance between the center axes of the cooling grooves is chosen so that it corresponds approximately to the distance of the jump animal during startup on the hill. Most suitable is the usual distance of 32 cm at ski jumping competitions.
  • the advantages of the invention are enhanced.
  • the required for the ski jumping snow pad is reduced to the required minimum width, namely the width of two jump skis plus some lateral play. As a result, the required amount of snow is reduced and the cooling effort is minimized.
  • the alternative starting track consists of a pair of alternative ruts running parallel to one another, whose bottoms are designed as a sliding surface.
  • the snow surface in the cooling starting track and the bottom of the alternative starting track are at the same height, since then the starting parabola for the ski jumpers does not change when changing from the cooling starting track to the alternative starting track.
  • the start-up parabola determines the geometric characteristics of the start-up. For an unchanged starting parabola, therefore, the cooling starting track and the alternative starting track should be arranged relative to each other so that the snow surface in the cooling intake lane in the filled state at the same height as the bottom of the alternative start-up lane.
  • cooling starting track and the alternative starting track are arranged offset in one another, i. when the two types of ruts, so cooling ruts and alternative ruts, are arranged alternately, so that in the space between the two cooling ruts an alternative ruts comes to rest and in the space between the two alternative ruts adespurrinne.
  • the total width of the run-up track can be kept low, so that the additional run-up track leads only to broadening by the width of a rut.
  • the existing from cooling start track and alternative start-up track is designed as a module that can be embedded in the surface of the Schanzendeckplatte. If the inrun track sunk so far that its upper edge is flush with the surface of the Schanzendeckplatte, so you can cover the inrun track with a cover and receives a flat ramp surface. This flat surface can be covered with snow, so that the jump can also be used in a conventional manner, that is, by complete coverage of the ski jumping surface with natural and / or artificial snow and molding of the inrun track in the closed snow cover. In this way, the inrun track according to the invention allows a multifunctional use of the ski jumping facility.
  • dynamometry plates are mounted under the bottoms of alternative ruts in the bounce area of the inrun track, preferably on the last eleven meters before the jump.
  • the dynamometric plates are used to measure the bounce developed by the ski jumper. The fact that the dynamometric plates under each of the two alternative ruts The bounce developed by each leg can be determined separately.
  • dynamometric plates consist of a bottom plate and a top plate between which the force sensors, e.g. piezoelectric elements are located.
  • the bottom plate is firmly connected to the ski jumping structure or with the built-in module.
  • the force sensors are attached, which in turn are firmly connected to the cover plate. It is particularly favorable if the base plate and the cover plate largely assume the width of the alternative groove, so that only a narrow gap remains to the lateral border of the alternative grooves.
  • cover plates of the Dynamometrieplatten then the bottom of the alternative ruts is attached.
  • the bottom of the alternative ruts is only supported by the dynamometric plates and is free to move up and down between the lateral surrounds of the alternative ruts.
  • cooling and alternative ruts are also underlaid with a common Dynamometrieplatte. This is achieved by Dynamometrieplatten, which are assigned to an outer and the respectively adjacent inner track groove together.
  • the mechanical decoupling must then take place in the middle of the four ruts between the two inner ruts. The decoupling can be done for example by a gap. Since the two right and the two left ruts are assigned to the same anklebone, the bouncing force developed by each leg of the skijumper can also be determined separately with this configuration of the dynamometric plates.
  • the Dynamometriepatten be mechanically decoupled in the start-up direction at regular intervals, preferably at a distance of one meter. This makes it possible to break down the strength development of the ski jumper in the take-off phase in terms of time and place. This decoupling can also be achieved by a gap between successive Dynamometrieplatten.

  • Bottom 24 and side walls 22 of the cooling run-track 20 form a box-shaped profile.
  • Snow 60, natural snow or artificial snow or a mixture of both, can be introduced into the cooling starting track 20.
  • the distance of the side walls 22 is chosen so that in the filled snow two ruts can be formed in the space required for ski jumping. On the other hand, the distance of the side walls 22 should not go well beyond the extent required to keep the cooling snow amount as low as possible. Ideally, a distance of about 50 cm appears for the side walls 22.

  • Particularly favorable is a width b of 13 to 14 cm.
  • the cooling grooves 30 and 31 are filled with natural and / or artificial snow 60. Since only the preferably 13 to 14 cm wide cooling grooves 30 and 31, but not the gap between the two cooling grooves with snow 60 must be filled, the need for snow 60 is comparatively low.
