Definitions

  • the invention relates to a ski boot, consisting of a shell forming a sole and a shaft which is articulated on the shell by means of at least one joint axis in the region of the inner and outer knuckles, the joint axis at least on one of the two ankle sides in the Shell is adjustable in height.
  • the load on the sole and thus the load on the ski depends, among other things, on the inclination of the lower leg with respect to a vertical plane through the longitudinal axis of the shoe. With a corresponding inclination of the lower leg, therefore, a torque is exerted on the shoe about the longitudinal axis of the shoe, which leads to a greater load on the inside or outside edge of the ski.
  • ski boots with a shaft that can be closed at the front with the aid of two locking flaps to store the articulated axis on the ankle side in an adjustable manner in the shell and in the desired, a specific one Clamp the height setting to the shell.
  • this inclination adjustment of the shaft is only practical for ski boot shafts provided with locking flaps and not for shafts which are composed of a closed front part of the shaft and a swiveling heel flap, because in particular the front part of the shaft largely is dimensionally stable construction part, so that when a hinge axis is adjusted in height, a gap must necessarily occur or be present between the shell and the front part of the shaft, which gap cannot be compensated for by locking flaps.
  • the invention is therefore based on the object of avoiding this deficiency and also for a ski boot with a hinged shaft, which is composed of an undivided front part of the shaft and a heel flap, to ensure an inclination adjustment for the shaft around an axis running in the longitudinal direction of the shoe with simple technical means.
  • the invention solves this problem in that the articulated axes on the two sides of the ankles are adjustably adjustable and are connected to an actuator.
  • the height of the axis of the connecting joint between the shaft and the shell is retained when the shaft is tilted, so that the axis of inclination essentially coincides with the axis of curvature of the shell in the region of the instep-side shaft connection.
  • the front part of the shaft cannot consequently lift off the shell and there is no disruptive gap between the shell and the shaft.
  • the travel for the actuator connected to the articulated axes is comparatively small because it corresponds to only half the travel that is necessary for the same shaft inclination with one-sided adjustment of the articulated axes. No special requirements therefore have to be made to the actuator.
  • the actuator can consist of a screw drive which is arranged in the sole and runs transversely to the longitudinal direction of the shoe and which has at least one regionally flexible tension and push member is connected to the bearing axles. Since this pulling and pushing element connects the joint axes on both sides of the ankle, the adjustment of the pulling and pushing element results in the required opposite adjustment of the jointing axes on the opposite side of the ankle by itself. It is only necessary to ensure that the pulling and pushing element both tensile and compressive forces can be transmitted.
  • tension and push member runs at least in the sole area in a guide channel, because in the transition area from the sole to the side wall of the shell not only the compressive forces occurring in the sense of buckling, but also the tensile forces to be transmitted in the sense a lifting of the tension and push member from the shell.
  • connection between the actuator and the tension and pushing element can be a in the ver have effective play direction. So that despite this game a good support of the foot and an immediate power transmission from the foot to the ski is achieved, the resistance to overcome the game can be chosen to be correspondingly large. An adapted sliding friction can be provided for this purpose. Particularly advantageous conditions result, however, if the tension and push element is supported resiliently with respect to the actuating drive, because a resetting force is ensured with such a resilient support.
  • pulling and pushing link can be designed differently, for example as a link chain, simpler conditions result if it consists of a leaf spring, because of the advantageous flexibility, which is not forced by any joints and which nevertheless allows a corresponding transmission of pressure force.
  • the shaft of a ski boot is composed of a front part of the shaft and a heel flap, the front part of the shaft and the heel flap being articulated on the shell not by means of common joint axes, but with the aid of separate hinge axes, then a shaft adjustment can also be carried out about an axis running in the longitudinal direction of the shoe, if the joint axes of the front part of the shaft and the heel flap are connected to each other on each side of the ankle and are jointly adjustable.
  • the adjustment of the joint axes connected to one another ensures the unchangeable assignment of the front part of the shaft and the heel flap to one another even when the joint axis is adjusted, so that the shaft shape is retained.
  • the connection of the joint axes on one side of the ankle can take place via the tension and push member itself, whereby a separate mounting for these joint axes can be omitted.
  • the ski boot shown consists essentially of a shell 1 with a molded-on sole 2 and of a shaft 3 which consists of two parts, namely a shaft front part 3a and a heel flap 3b.
  • the arrangement is such that the heel flap 3b is articulated on the shell 1 via two hinge axes 4 and the front shaft part 3a via two separate hinge axes 5, the hinge axes 5 for the front shaft part 3a covering the heel flap 3b overlapped by the front shaft part 3a in a passage opening 6 Push through with play to ensure the free pivotability of the heel flap 3b relative to the front part 3a of the shaft.
  • an actuating drive 8 is provided, which is designed as a screw drive and has an adjusting screw 9, which is displaceably fixed in the sole 2 but rotatably held, with an adjusting nut 10 guided in a rotationally fixed manner.
  • This adjusting nut 10 is connected to a tension and thrust member 11, which is designed as a leaf spring 12 and in which the articulated axes 4 and 5 are held so that when the adjusting screw 9 is actuated, the articulated axes 4 and 5 on the two sides of the ankles in opposite directions their slots 7 are adjusted.
  • This adjustment of the joint axes 4 and 5 results in an inclination adjustment of the shaft 3 about an axis running in the longitudinal direction of the shoe, which allows the adaptation of the shoe to the respective anatomical conditions to compensate for unilateral longitudinal edge loads without the occurrence of a gap between the shell 1 and the front part of the shaft 3a fear in the instep area of the shoe.
  • the invention is of course not limited to the exemplary embodiment shown, because the only thing that matters is to adjust the shaft inclination about an axis running in the longitudinal direction of the shoe by adjusting the height of the joint axes in the ankle region between the shaft and the shell.
  • the shaft front part 3a and the heel flap 3b of the shaft 3 could be jointly articulated on the shell 1 about the joint axes 5, so that the joint axes 4 are omitted.
  • the ski In order to avoid excessive edge insertion during ski guidance, the ski must be able to lay flat on the respective floor shape. However, this is not possible with a rigid support against the foot. For this reason, the shaft 3 should be movable to a certain extent transversely to the longitudinal direction of the ski relative to the shell 1.
  • the connection between the leaf spring 12 and the adjusting nut 10 can have a play in the adjustment direction, which must first be run through before the leaf spring 12 provides a rigid support of the shaft with respect to the shell.
  • Such play can be ensured by interposing a spring, for example a rubber spring. But it would also be possible to mount the actuator 8 to a limited extent in the sole and to support it resiliently with respect to the sole.
