Definitions

  • the invention relates to an outsole for cross-country ski boots with a front sole extension, by means of which the outsole can be attached to the ski by means of a ski binding, and with at least one groove or rib provided on the front sole and open to the running side, which has a correspondingly shaped and extending rib or Groove on the top of the ski can engage in positive engagement. Furthermore, the invention relates to a base plate which can be used in combination with an outsole of this type.
  • longitudinal ribs and longitudinal grooves which are provided on the running side of the front sole of cross-country ski boots and on the upper side of the ski, is used to give the skier lateral support in addition to the retention effect of the binding (cf. DE-AS 26 22 966) .
  • the longitudinal ribs and longitudinal grooves increasingly fit into one another during the return movement of the outsole from the raised and bent position toward the top of the ski and prevent the ski boot from deviating sideways as a result of the result Positive connection.
  • the cooperating longitudinal ribs and grooves are designed in such a way that they can still engage with each other with a certain lateral offset and to a certain extent have an "alignment function" (eg due to obliquely rising flanks), but with a somewhat greater lateral offset this " Alignment function "is noticeably noticeable to the skier as a shock when the boot is placed on the ski, and the longitudinal rib and longitudinal groove no longer meet when the boot is particularly strongly offset.
  • the invention is therefore based on the object of improving a cross-country ski boot of the type described in a simple manner in such a way that even when it is relatively far off the top of the ski Ski boot ensures better lateral support.
  • the sole section between the sole tip and the ball area has at least one transverse groove or transverse rib which runs transversely to the outsole and which is assigned a correspondingly shaped and extending transverse rib or groove on the upper side of the ski for positive engagement.
  • the invention is based on the consideration that when the ski boot is lifted relatively far from the top of the ski, a reasonably effective positive engagement can only take place in the area that is still in contact with the top of the ski in this phase or at least relatively early on Return movement of the boot to the ski comes into contact with the top of the ski again.
  • a sufficient form fit can only be obtained relatively late.
  • the complete form fit over the entire length of the rib or groove is established immediately as soon as this part of the outsole is rolled up the top of the ski has come into contact with it.
  • the flanks of the groove and the rib can come fully to bear against one another, so that they exert the desired additional holding action against lateral movement of the sole.
  • transverse groove or rib provided according to the invention is combined is with one or more of the known longitudinal grooves or ribs. This compensates for the rarely to be avoided deviations and games, which in some cases are even deliberately provided, between the ribs / grooves of the sole of the shoe and the grooves / ribs of the base plate, so that a more precise guidance is the result.
  • transverse groove or grooves provided in accordance with the invention and the ribs engaging therewith are located in the zone of the outsole in which a strong bend occurs with simultaneous support on the upper side of the ski.
  • this bending zone lies in the rear end region of this sole extension, i.e. at the transition between this and the actual front sole.
  • the transverse grooves in the outsole penetrate the lateral sole edge, i.e. are open. This makes it easier for snow or dirt to penetrate to the side. This measure is supported by the fact that, with the depth of the transverse groove remaining constant, the height of the transverse rib engaging therewith decreases somewhat from the center of the sole towards the outside.
  • a cross-country ski boot with an outsole according to the invention consists of a shaft 1, the shape and form of which are not important here, and of an outsole 2 connected to the shaft 1, which is made of a flexible plastic, e.g. hard set polyamide, or made of rubber.
  • a profiling not shown, is provided, which offers a certain level of slip resistance when walking.
  • the outsole 2 has a sole extension 4, the width of which is smaller than the ski width and which forms a front, thickened end region 5 with a shoulder 6 pointing towards the rear.
  • a pair of transverse grooves 9, 10 are provided in the immediate vicinity of the transition 7 between the front sole extension 4 and the actual outsole 2, which have the same triangular cross section as the longitudinal groove 3 in the embodiment shown and penetrate both the longitudinal groove 3 and the lateral sole edge.
  • the depth of the grooves 3, 9 and 10 is essentially constant over their length.
  • the thickness of the outsole 2 is dimensioned in relation to this depth so that the required strength of the outsole 2 is not impaired.
  • FIG. 3 shows the binding area of a cross-country ski 12 as well as a hint 13 of a ski binding, by means of which the front end area 5 of the sole extension 4 can be fixed rigidly on the upper side of the ski.
  • the cross-country ski boot is prevented from unwanted release from the bracket 13 by a locking element (not shown), for example a pin passing through the front end area 5 and the bracket 13 in the area of a transverse bore 14.
  • the binding can be, for example, of the type described in the aforementioned DE-AS 26 10 041. However, the type of binding is not important for the present invention.
  • a base plate 15 made of metal or plastic is attached to the top of the ski and has a raised longitudinal rib 16 and two transverse ribs 17, 18.
  • the mutual spacing of the transverse ribs 17, 18 corresponds to that of the transverse grooves 9, 10; the cross-sectional shape of the ribs 16, 17 and 18 is complementary to that of the grooves 3, 9 and 10.
  • FIG. 3 shows the cross-country ski boot in a position raised from the top of the ski, for example in the phase in which the cross-country skier has the rear leg at the step at the end of the printing process moved forward again, the outsole 2 previously bent in the region of the transition 7 by almost 90 ° relative to the upper side of the ski returning to the upper side of the ski and rolling on the upper side of the ski while reducing the bend.
  • any other suitable cross-sectional shape for example trapezoidal shape or a combination of triangular and rectangular shape, can be selected.
  • trapezoidal shape for example trapezoidal shape or a combination of triangular and rectangular shape.
  • it can also be considered to make these grooves semicircular in cross section.
  • transverse grooves This is achieved, for example, by choosing the depth of the transverse grooves to be greatest where the strongest bend is desired, for example behind the transition 7 between the sole extension 4 and the outsole 2, where, due to the formation of the grooves, the outsole thickness compared to the thickness of the sole extension 4 increases.
  • a single transverse groove with one is sufficient cross rib on the base plate (or vice versa). If, however, several transverse grooves are provided for the purpose just described to influence the curve of the sole, it is advantageous to assign corresponding transverse ribs on the base plate and thereby to improve the alignment and holding function.
  • the projecting ribs on the outsole and accordingly the grooves on the top of the ski can be provided, and that a combination in the form is possible that the outsole and the base plate both ribs and also have grooves.
