Definitions

  • the invention relates to a ski equipped with metal edges, the tread of which has a central horizontal region in cross-section and has rigidly connected upwardly extending lateral regions on both sides thereof, the tangents extending normal to the longitudinal direction of the ski to the lateral regions which extend at least across the width of the steel edges, form an obtuse angle with one another, the apex of which lies below the tread and preferably in the vertical longitudinal median plane of the ski and the undersides of the steel edges parallel or tangential to the chamfered areas and preferably flush in the chamfered areas of the ski Tread are arranged.
  • skis are usually equipped with an essentially flat running surface, with a groove which runs approximately in the middle and is arranged approximately in the longitudinal direction of the ski and 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.
  • sharpened edges it was often felt to be disadvantageous that even slight uncertainties in the load on the ski lead to excessive use of edges and thus to tilting.
  • a slight ability to turn was generally observed with sharp edges and such skis were therefore primarily suitable for downhill skiing.
  • FR-A-21 44 146 a ski with a trapezoidal tread in cross section has become known.
  • the width of the central, non-beveled area is significantly smaller than the beveled areas, which include a bevel angle of about 10 ° with the horizontal.
  • a tread configuration has become known in which the beveled partial areas extend close to the central plane of the ski and the tangents to the beveled areas enclose angles of between 140 ° and 180 ° with one another.
  • 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 lateral areas running upwards 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 lateral, upwardly sloping areas only come into engagement with the slope when the ski is tilted by a considerable angle, and so swinging with such a ski is not made easier either.
  • 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 Swinging 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 consists in that the tangents running normal to the longitudinal direction of the ski at the lateral areas enclose an obtuse angle of 174 ° to 178 ° with one another, that the width of the central cross-sectional area of the tread is greater than the total width of the chamfered, upwardly extending areas and that the undersides of the steel edges are arranged parallel or tangential to the chamfered areas in the uncut state and preferably flush in the chamfered areas of the tread.
  • 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 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 exercise is therefore preferably made such that the undersides of the steel edges are arranged parallel or tangential to the chamfered areas in the uncut state and preferably flush in the chamfered 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 tread at least in the area of Metal edges with the substantially flat central area of the tread encloses an acute angle and extends from the central area upwards.
  • the fact that the tread rises in its lateral areas compared to the central area means that a reduction in 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.
  • 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 be such that the tread is angled at both edges seen in cross section.
  • such an angled design is advantageous, in which angular gradations in the tread are provided 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 design is such that the lateral regions of the tread extend over a width at an acute angle to the central region 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 running 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 beveled 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 regions 4 intersect one another in the longitudinal median plane 6 of the ski at an intersection angle between 174 ° and 178 °.
  • 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.
