Definitions

  • the invention relates to a method for producing a structured running surface for sliding devices, e.g. Skis, as well as a structured tread produced by this method.
  • a targeted tearing of the water film is through the AT 398 038 B a ski with a macrostructured tread in the form of straight and parallel to each other, running in the longitudinal direction of the ski longitudinal grooves has been proposed, wherein the longitudinal grooves between 3 and 20 mm in length, between 0.05 and 0.25 mm width and between 0.01 and 1 mm in depth and are arranged in rows and offset from one another in the longitudinal direction of the ski.
  • extruded polyethylene coverings are used as the covering material.
  • the covering material For top-of-the-line products and in racing, especially skating rinks made of sintered, high molecular weight low-density polyethylene are in use.
  • the running surfaces including the steel edges In order to achieve optimal sliding and driving performance of the skis, the running surfaces including the steel edges must be ground. This is done by band grinding or stone grinding.
  • the belt grinding is an abrasive belt whose band, binder, abrasive grain size and the way of working the ski run surface have been optimized.
  • Stones are bonded abrasives whose classification is based on different aspects: for example, the purpose or type of raw materials used, for example natural (glass, pumice, quartz, garnet, corundum, diamond) or artificial (silicon carbide, boron carbide , Cubic boron nitride, synthetic diamond), or increasing hardness (1000 to 7000 kp / mm 2 according to KNOOP) and grain size (0 to 5000 ⁇ m).
  • natural glass, pumice, quartz, garnet, corundum, diamond
  • artificial silicon carbide, boron carbide , Cubic boron nitride, synthetic diamond
  • increasing hardness 1000 to 7000 kp / mm 2 according to KNOOP
  • grain size 0. to 5000 ⁇ m
  • the grinding wheels are then trued with special tools (such as diamonds, hard metals, ceramics, etc.), whereby special tread structures are achieved.
  • special tools such as diamonds, hard metals, ceramics, etc.
  • An optimally ground ski consists of a macrostructure (> 20 ⁇ m depth and optically visible) and a microstructure ( ⁇ 10 ⁇ m depth and visible only under the microscope).
  • the macrostructure is achieved during grinding by removing the grindstone with diamonds. Due to different settings (speed, feed, shape, infeed, etc.), the macro structure can be largely adapted to the requirements.
  • microstructure can not be controlled by grinding and is dependent on a large number of factors.
  • the material parameters material, manufacturing process, etc.
  • the grinding parameters stone type, stripping conditions, grinding conditions, grinding machine, etc.
  • the environmental conditions temperature, humidity, space, etc.
  • the CH-A-641 683 discloses a ski with a defined macro and microstructure.
  • the macrostructure is made by means of an embossing process, and the microstructure is determined by the use of different materials.
  • a tread has become known in which instead of the usual in cross-country skis a return-inhibiting microstructure is proposed.
  • Such climbing aids were produced by dry grinding by sanding the tread with abrasives with very abrasive means, with the result that a fur-like, hairy structure has arisen, based on the previous or alternative climbing aids, such as sticking on fur skins, seal skins u .ae. has presented an alternative.
  • the object of the invention is to improve the sliding properties of ski running surfaces compared to the known measures. This object is achieved by the measure of claim 1. If the microstructure and the macrostructure are produced in the same machining process, a rational production method with associated production improvement takes place.
  • the microstructure is produced by embossing rollers, whereby a simple design of the system at higher contact pressures than is possible with embossing bands, can be achieved.
  • embossing rollers can be used.
  • the tread from front to rear on different structures.
  • a defined micro- and macrostructure is applied simultaneously or in succession with the aid of embossing rolls or dies.
  • the microstructure can be adjusted in these rolls, for example via fine hammer mechanisms with fine needles, hard metal needles or, for example, via laser processing of the roll. It is also possible to apply the microstructure by means of targeted sandblasting or targeted chemical interventions, such as various mordants, for example, to expose grain boundaries of the steel material or aluminum material of the rolls in order to specifically adjust the microstructures in the region of 10 ⁇ m depth and down to the nanoscale to be able to.
  • the structuring is applied under the action of heat.
  • the boundary layer of the covering surface is briefly heated to very high temperatures, so that the polyethylene enters the plastic state in which the pattern is embossed.
  • the plastic mass solidifies very quickly, and the profile or the relief remains behind in the embossing process.
  • a further subject of the invention is a running surface for sliding bodies, which has a structuring produced in the stamping process and contains a microstructure and / or a macrostructure.
  • a tread can be made independently of the slider and applied to the slider. In the context of the invention, however, it is also provided to provide the slider with a tread on which the structuring is applied in the embossing process.
  • slipper or “slide” are to be understood in the broadest sense of the word, including not only skis and snowboards, but also any other vehicle or vehicle to understand, in which the structuring of the invention improves the driving characteristics of the vehicle.
  • Fig. 1 1 denotes a ski running surface on which a microstructure 2 and a macrostructure 3 are applied. Both the microstructure and the macrostructure can be embodied in various forms.
  • the microstructure is provided in a parallel array.
  • the orders of magnitude are in the Length L to 100 microns, in width B to 20 microns, in depth T to 6 microns, the longitudinal distance A to 100 microns, and the line spacing Z to 100 microns.
  • Fig. 6 shows a microstructure with a staggered array.
  • the angle ⁇ is advantageously between 20 ° and 70 °.
  • FIGS. 7 and 8 show an asymmetric shape that has different sliding properties back and forth. This property is especially appreciated by cross-country skiers to allow both gliding and climbing.
  • Fig. 9 shows a diagonal pattern with a uniform row arrangement, wherein the lines are inclined at an angle ⁇ to the running direction.
  • Fig. 10 shows a diagonal pattern with alternating right and left structures.
  • Fig. 11 shows an X-shaped pattern.
  • Fig. 12 shows a tulip-shaped pattern, which can also be used as a climbing aid in cross-country skis.
  • Fig. 13 shows a star-shaped pattern, which has very good sliding properties, especially in wet snow conditions.
  • Fig. 14a shows a boat-shaped depression, which is uniform after Fig. 15a or non-uniformly Fig. 16a can be trained.
  • Fig. 14b shows a circular recess, which also, like Fig. 15b shows, uniform or corresponding Fig. 16b can be uneven.
  • Fig. 14c shows a square shape, which accordingly Fig. 15c evenly or how Fig. 16c shows, can be uneven.
  • Fig. 14d shows a needle-shaped form, which also according to Fig. 15d evenly or appropriately Fig. 16d can be uneven.
