Definitions

  • the invention relates to a ski with a tread and metal edges arranged on the lateral edges of the tread.
  • Conventional skis of this type are usually equipped with an essentially flat running surface, a groove which is arranged in the longitudinal direction of the ski and is arranged approximately centrally is usually provided to improve the guiding properties.
  • Suitable materials have been developed as a covering for the tread in order to improve the sliding properties.
  • a ski has become known, the tread of which, viewed in cross-section, has a central horizontally extending region and lateral regions extending upwards on both sides thereof.
  • the width of the central area is relatively small and corresponds approximately to the total width of the two lateral areas running upwards.
  • the upwardly extending lateral areas are very steeply beveled and, viewed in cross section, form an angle of approximately 140 ° with one another. These steeply sloping side areas therefore do not contribute to guidance when driving straight ahead and this results in great uncertainty when driving straight ahead.
  • the steel edges of these sides come up tapered areas only engage with the slope when the ski is tilted by a considerable angle and it is therefore not easier to swing with such a ski.
  • the invention has for its object to provide such a ski equipped with metal edges, the tread in cross-section a central horizontal area and on both sides of the same rigidly connected, upwardly extending side areas so that an edge insert and thus a safe Swing down is maintained to the usual extent, however, the rotatability of the ski on the slopes is facilitated, ensuring safe guidance when driving straight ahead.
  • the invention essentially consists in that the tangents running normal to the longitudinal direction of the ski at the lateral areas, which extend at least across the width of the steel edges, enclose an obtuse angle of 170 to 179 °, preferably 174 to 178 ° , whose apex is below the tread and preferably in the vertical longitudinal center plane of the ski and that the width of the central area of the tread running horizontally in cross section is greater than the total width of the bevelled, upwardly extending areas.
  • the fact that the width of the central area of the tread running horizontally in cross section is greater than the entire width of the beveled areas ensures good guidance when driving straight ahead.
  • the design is preferably such that the tread at least in the area of the metal edges with the substantially flat includes an acute angle in the central area of the tread and runs upwards from the central area.
  • the fact that the tread rises in its lateral areas from the central area means that a reduction in the straight-line stability is accepted, but the rotatability of the ski is made considerably easier.
  • the straight running properties can be easily mastered by appropriately designed central grooves. However, the fact that the skis can be turned more easily on a wide variety of slopes and above all on loose, unconnected snow is perceived as a great advantage.
  • the design can preferably be such that the tread is angled in cross-section on both edges.
  • such an angled design is advantageous, in which angular gradations are provided in the tread on both sides of the longitudinal center plane in the longitudinal direction of the ski.
  • such an angular design is also distinguished by a high degree of good guiding properties in straight running.
  • the steel edges usually arranged on the side edges of the tread of a ski are mostly hardened or surface-treated in order to give good wear properties.
  • the design is therefore particularly preferably such that the undersides of the steel edges are arranged parallel or tangential to the beveled areas in the uncut state and preferably flush in the beveled areas of the tread.
  • the chamfer should therefore not be formed by grinding the finished ski, since this would adversely affect the material properties of the steel edges.
  • the design is such that the lateral areas of the tread extend over a width at an acute angle to the central area of the tread, which corresponds to the width of the metal edges.
  • Such a slight beveling of the lateral areas of the tread is sufficient to improve the rotatability and has hardly any effect on the straight running properties.
  • the width of the upwardly extending regions of the tread is preferably less than 10 mm or even less than 5 mm.
  • the width of a ski in the area of the binding is usually 65 to 70 mm.
  • the width of an upwardly extending lateral region is therefore preferably less than 1/7 of the width of the ski.
  • FIG. 1 shows a cross section through a first embodiment of a ski according to the invention
  • FIG. 2 shows a partial cross sectional view through a modified embodiment
  • FIG. 3 shows a perspective view of a ski.
  • the 1 shows a ski 1, the tread 2 of which is chamfered in the area of the metal edges 3.
  • the beveled areas are designated by 4 and edges 5 are formed between the substantially flat area 2 'of the tread 2 and the beveled areas 4 in the longitudinal direction of the ski.
  • the chamfered areas 4 extend essentially over the area of the lateral metal edges 3 and enclose an angle of 0.5 to 3 ° with the flat area 2 'of the tread 2.
  • the tangents to the lateral areas 4 intersect at an angle in the longitudinal center plane 6 of the ski between 170 ° and 179 °, a cutting angle between 174 ° and 178 ° being particularly preferred.
  • the surface of the ski is denoted by 7 and the side surfaces, which are designed to converge upwards in the illustration according to FIGS. 1 and 2, are denoted by 8.
  • the side surfaces 8 are of a stepped configuration and in turn the lateral regions 4 of the metal edges 3 are chamfered relative to the central region 2 'of the tread 2.
  • the lateral areas 4, which are bevelled to the central area 2 'of the tread 2, extend over a width of about 5 mm.
  • FIG. 3 shows the area over which the length of a ski is chamfered in areas 4 of the outsole 2. This is the area in which the ski rests on the slope and this area is designated by a in FIG. 3.
