Description

EXAMPLES

[0037] The object of the present invention is illustrated in the examples in drawings, FIGS. 1 to 4 illustrate different variants of the binding, FIGS. 5 and 6 illustrate the principle of action of the binding, and FIGS. 7 to 9 illustrate adapters for mounting the bindings, FIGS. 10 and 11 illustrate the binding having frame, FIGS. 12 and 13 illustrate the shoe according to the invention. The term ski used in the examples includes all kinds of skis, and splitboards, rollers skis or snowshoes.

Example 1

[0038] To a ski 1 a plate 2 is mounted. (FIG. 1). The front of the plate 2 may be lifted upwards. To the plate 2 a shoe clamp 3 is mounted. The shoe clamp 3 permits free lifting and movement of the shoe heel. The plate 2 is connected with the ski 1 by hinge bonding 4. Between the plate 2 and the ski 1 there is a spring 5 mounted under the midfoot of the shoe.

Example 2

[0039] To a ski 1 a plate 2 is mounted (FIG. 2). The plate 2 is elastic. To the plate 2 a shoe clamp 3 is mounted. The shoe clamp 3 permits free lifting and movement of the shoe heel. The plate 2 is connected with the ski 1 by stiff bonding 4. Between the plate 2 and the ski 1 there is an elastic plate 5 connected with the ski by an articulated joint in its back part and by stiff bonding in its front part. The elastic plate 5 is bent upwards to create an arching. The plate pressed from the top straightens, and then comes back to the previous shapewhen there is no pressure.

Example 3

[0040] To a ski 1 a plate 2 is mounted (FIG. 3). The front of the plate 2 may be lifted upwards. To the plate 2 a shoe clamp 3 is mounted. The shoe clamp 3 permits free lifting and movement of the shoe heel. The plate 2 is connected with the ski 1 by hinge bonding 4. Between the plate 2 and the ski 1 there is a spring 5. The spring 5 is mounted to the front part of the plate.

Example 4

[0041] To a ski 1 a plate 2 is mounted 2 (FIG. 4). The front of the plate 2 may be lifted upwards. To the plate 2 a shoe clamp 3 is mounted. The shoe clamp 3 permits free lifting and movement of the shoe heel. The plate 2 is connected with the ski 1 by spring bonding 4. The mounting is placed between the back and the middle part of the plate 2.

Example 5

[0042] A ski shoe is mounted in the binding 3 (FIG. 5). The skier taking the step lifts the heel and presses the toes to the ski. Then the skier lowers the heel and lifts the toes (FIG. 6). The front of the ski shoe lifts together with the plate 2 upwards, and the heel rests on the plate 2 and presses its back part to the ski 1. Thanks to that the skier is able to move on the skis in a way maximally close to physiological walking.

Example 6

[0043] To a ski 1 a plate 2 is mounted 2 (FIG. 7). The plate 2 is elastic. The plate 2 is connected with the ski 1 by stiff bonding 4. Between the plate 2 and the ski 1 there is an elastic plate 5. The elastic plate 5 is connected with the ski by an articulated joint in its back part and by stiff bonding in its front part. The elastic plate 5 is bent upwards to create an arching. The plate pressed from the top straightens, and then comes back to the previous shapewhen there is no pressure. To the plate 2 a standard ski binding 6 is fixed, in which the shoe toes clamp 3 permits lifting of the shoe heel. The binding 6 has a shoe heel clamp permitting to immobilize the heel during the slide.

Example 7

[0044] Toa ski 1 a plate 2 is mounted 2 (FIG. 8). The plate 2 is elastic. To the plate 2 a shoe clamp 3 is mounted. The plate 2 is connected with the ski 1 by stiff bonding 4. Between the plate 2 and the ski 1 there is an elastic plate 5. The elastic plate 5 is connected with the ski by an articulated joint in its back part and by stiff bonding in its front part. The elastic plate 5 is bent upwards to create an arching. The plate pressed from the top straightens, and then comes back to the previous shapewhen there is no pressure.

Between the plate 2 and the ski 1 there is an elastic plate 5. The elastic plate 5 is connected with the ski by an articulated joint in its back part and by stiff bonding in its front part. The elastic plate 5 is bent upwards to create an arching. The plate pressed from the top straightens, and then comes back to the previous shapewhen there is no pressure. To the plate 2 a standard ski binding 6 is fixed, in which the shoe toes clamp 3 permits lifting of the shoe heel. The binding 6 has a shoe heel clamp permitting to immobilize the heel during the slide.

Example 9

[0046] The binding comprises a stiff plate 7 fixed to the ski 1. To the stiff plate 7 from the top an elastic plate 8 is mounted in a way permitting to lift upwards the front part of the elastic plate 8. The stiff plate 7 in its front part is mounted on a hinge 9 to the ski 1 in a way, which permits to lift upwards the back part of the plate 7. The elastic plate 8 and the stiff plate 7 are connected by frame 10 by hinge bonding 11. The frame 10 is used for mounting the shoe and constitutes a scaffold connecting both plates and enabling movement of the toes and the heel upwards and downwards. At the bottom of the stiff plate 7, between the plate 7 and the ski 1 there is a support for the heel 12. The plate 7 may be immobilized by a clamp 13, in order to enable safe slide.

Example 10

[0047] A shoe for riding skis/splitboard/roller skis 17 is mounted to the ski 1 in a binding permitting to lift the heel 6. The sole of the shoe 14 consists of two layers connected with each other in the area of the heel. The bottom layer of the sole 15 is stiff, and it is intended for mounting in the bindings, while the upper layer of the sole 16 is elastic and permits to lift the toes upwards.
