Definitions

  • a joint must be supplied with nutrients through constant movement. Even a muscle that is not used, for example in a plaster cast, regresses and atrophies. In summer it is relatively easy to take these conditions into account and to do sports more or less sensibly. But in winter, when there are considerable limits to a sporting activity due to snow and ice, the natural urge to move also demands its right. Skiing is one of the few options for winter sports.
  • the FIS has 100 national associations. Because of the large number of skiers and snowboarders and their different downhill behavior, the FIS set up a generally binding rule on behavior in ski areas and on ski slopes.
  • the most important element in the system that a skier uses in connection with the skis is the connecting element between these two parts. That is, as an interface, the ski boot or ski boot. It represents the important and sometimes critical link between man and machine.
  • a ski boot had a rigid shell, which was split into two at the top, to accommodate an inner boot that in turn received a skier's foot, and that this rigid shell had a rigid sole and a the heel enclosing the heel.
  • This winter sports shoe is characterized in that the front part of the outer shoe is largely decoupled from the rear part of the outer shoe by means of a flexible transition area provided in the metarsal area (metatarsus between the foot root and toes). This enables the forefoot to roll in the ball of the foot around an axis of rotation transverse to the longitudinal axis of the ski boot.
  • the outer shoe upper and the molded-on side parts up to the metatarsal region are essentially rigid, so that a bending force can be introduced into this area of the sole by means of the outer shoe upper.

  • different solutions are shown in this document for the problem of the flexible shell part in the forefoot area.
  • various new shapes, constructions and design studies of the liner are presented. This new conception of the construction of ski boots allows a much better adaptation of the shoe to the different foot shapes that occur in practice, but wishes remain open here too, especially considering the weight of the user of the ski shoe.
  • the present invention is therefore based on the object, starting from the described prior art, to enable the adaptation of such a ski boot to different foot shapes and weights of the skier.

  • a sole cover (16) is fastened with the four fastening elements (17) shown.
  • This sole cover primarily serves to keep a distance from the ski and, via its recess provided in the area of the damping elements, to allow room for the movement possibilities of these damping elements (14) or the bending of the sole. For a closer look, reference is made to FIG. 5.

  • the two joints (4) and (5) consist of roller-shaped elements whose length is matched to the sole width at their respective installation location. This adjustment to the sole width is expressed in such a way that the roller-shaped joints slightly exceed the sole width on each side and the resulting protrusions into corresponding recesses in the fixed part of the outer shell protrude. So that the joints (4) and (5) can also move vertically according to the vertical load by the user, the recesses mentioned have an elongated, vertically running shape. This detail is shown in Figure 8.

  • This construction differs from that described in FIG. 7 essentially by the different arrangement of the leaf springs (2) and (3). While in FIG. 7 the two leaf springs run essentially parallel, in FIG. 9 the upper leaf spring (2) and the lower leaf spring (3) overlap in the central area of the sole. In this transition zone, both leaf springs are recessed in a certain range up to half their width, the other spring running through the recess in one spring.
