Definitions

  • the invention relates to a device for lateral guidance of a ski boot according to the preamble of claim 1.
  • the invention has for its object to provide a solution that manages with a normal thick sole of the ski boot even in the ball area.
  • the ratio of the lengths of the two guide strips of a ski is between 1: 1.1 and 1: 1.6.
  • the cross sections of the two guide strips can be formed by triangles of the same size. It is important in any case that for the phase of pushing off the ski boot on the ski, secure support is guaranteed, and that the ski boot is able to guide the ski safely even under different running conditions. According to the invention, different solutions are provided to achieve such different goals.
  • the outer surface of the inner bar which is most strongly stressed by the repulsive force, is increased relative to that of the outer bar, so that the total effective area of the shorter bar equals or, if necessary, exceeds the area of the longer bar can be designed.
  • breaking of the strips is reliably avoided even if the outer boundary surfaces of the two strips should run very steeply with respect to the plate carrying them.
  • the measure of claim 8 makes the production of the plate particularly simple, and the stability of the plate is increased.
  • FIG. 1 is a top view of the ski bindings of a pair of cross-country skis, with ski boots indicated in the ski bindings.
  • Fig.2 is a section along the line II-II in Fig.1. on a larger scale. 3 to 6 variants for the execution according to Fig. 2 are illustrated.
  • a ski binding 2a or 2b in which the front end of a ski boot 3a or 3b is clamped, is attached to a cross-country ski 1a or 1b.
  • two guide strips 4a, 5a, 4b, 5b are arranged on the top of each ski 1a and 1b.
  • These guide strips 4a, 5a, 4b, 5b could be attached individually to the top of cross-country skis 1a or 1b.
  • the two guide strips 4a, 5a, 4b, 5b of each ski 1a and 1b are not of the same length, the strips 4a, 4b on the inside of the ski 1a, 1b being shorter than the outer strips 5a, 5b are.
  • the course of the inner lasts 4a, 4b is concentrated on the area of the ball which is decisive for pushing off, whereas the outer lasts 5a, 5b provide increased support for the ski boot 3a in the sliding phase for ski guidance.
  • the cross sections of the two strips 4a, 5a are formed by two isosceles triangles, which are arranged symmetrically with respect to the vertical longitudinal plane of the ski.
  • the slope of the outer surface 24c of the inner rail 24a is greater than that of the inner surface 25c of the outer rail 25a, with the same height of the rail. In this way, the greater repulsive force acting on the inner bar 24a, despite the shorter configuration of this bar 24a, is reliably accommodated.
  • the base angle ⁇ 1 of the outer surface 24c of the inner bar 24a to the plate 26a is greater than the base angle ⁇ 2 of the inner surfaces 25d of the outer bar 25a to this plate 26a.
  • the variant according to FIG. 6 is characterized in that the plate 46a is not flat in the area between the two strips 44a, 45a, but has a concave surface 47a.
  • the surface 47a between the two strips 44a, 45a is formed by the section of a circular-cylindrical outer surface.
  • the outer surfaces 44c, 45c of the strips 44a and 45a form the same angle ⁇ with the plate 46a.
  • the concave surface can also be formed by cylinder sections with different radii, these sections possibly merging into one another with roundings.
  • FIGS. 2 to 6 have been described in connection with right-hand devices.
  • the left-hand device will be designed according to the configuration of the right-hand one.
  • different devices can be used on a pair of skis. This can be particularly advantageous for skiers with marked differences on the right and left foot and / or in their skiing ability on both sides.
