DESCRIPTION OF PREFERRED EMBODIMENTS

[0058] In the Figures, a skibinding 1 is shown. The skibinding is preferably a touring skibinding, an alpine ski binding, a telemark ski binding or a cross-country ski binding or a binding for a divisible snowboard.

[0059] The skibinding 1 comprises a support element 2 which can be attached to the ski, a bearing element 3 with a skiboot reception 4 which is designed in such a way that the skiboot 5 is mounted in the skiboot reception 4 so as to be pivotable about a first pivot axis S1 with respect to the skiboot reception 4, and a convex supporting surface 6 on which the skiboot 5 can roll. The bearing element 3 is pivotably connected to the support element 2 via a second pivot axis S2.

[0060] The support element 2 has a base plate 10. Two spaced bearing blocks 11 project from the top of the base plate 10. The underside of the base plate is a mounting surface 27 which rests on the upper surface of a ski not shown in the figures. The mounting surface is thus parallel to the surface of the ski. The base plate 10 includes a plurality of bearing openings 12 through which the support element 2 can be secured to the ski. The bearing blocks 11 provide the bearing sites for the pivotable mounting of the bearing element 3.

[0061] The bearing element 3 can be pivoted relative to the support element 2. The bearing element 3 is partially located between the two bearing blocks 11. Each of the bearing blocks 11 has a bearing opening 12. The bearing openings 12 are thereby arranged in alignment with one another. A bearing bolt 13 extends through the two bearing openings 12 and the space between the two bearing blocks 11. The bearing element 3 is mounted on the bearing bolt 13. The bearing bolt 13 defines the second pivot axis S2. In one variant, the bearing bolt 13 is pivotably mounted in the bearing openings 12 and the bearing element 3 is fixedly connected to the bearing bolt 13. In another variant, the bearing bolt 13 is fixedly mounted in the bearing openings 12 and the bearing element 3 has an opening through which the bearing bolt extends in such a way that the bearing element 3 can be pivoted to the bearing bolt 13.

[0062] The bearing element 3 is connected to the support element 2 so that it can be pivoted about the second pivot axis S2 from an initial state to a pivoted state. The skiboot reception 4 lies outside the space between the two bearing blocks 11.

[0063] As previously explained, the bearing element 3 is formed with a skiboot reception 4. In the embodiment shown, the bearing element 3 has two bearing sections 24, which bearing sections 24 extend radially to the second pivot axis S2. In the embodiment shown, the two bearing sections 24 extend away from the bearing bolt 13. The two bearing sections 24 are spaced apart, such that a space is created between the bearing sections 24. The skiboot 5 can project into this intermediate space. Further, the skiboot reception 4 is located at the free end of the bearing sections 24. In the embodiment shown, the skiboot reception 4 has a pin 25 on each of the bearing sections 24, which projects into the intermediate space between the two bearing sections 24. The two pins 25 extend along the same axis and engage bearing sites 23 on the skiboot 5. The pins 25 and the engagement in the bearing sites 23 thereby define the first pivot axis S1. The bearing section 24 further comprises a joint 26, the free end being pivotable about the joint 26 so that the pin 25 can engage the bearing sites on the skiboot 5 via the joint 26. Preferably, the joint 26 and/or the bearing section 24 is blocked for movement from the standing state to the pulling state so that the skibinding cannot open.

[0064] The convex supporting surface 6 on which the skiboot 5 can roll is provided in the embodiment shown by a bottom plate 20 with a convex upper side 19 and by a convex underside 21 of the skiboot 5. The skiboot 5 can roll on the convex supporting surface 6.

[0065] The first pivot axis S1 runs parallel to the second pivot axis S2 and the first pivot axis S1 can be pivoted by a pivot angle cc about the second pivot axis S2. The maximum pivot angle cc of the first pivot axis S1 about the second pivot axis S2 is preferably in the range from 10° to 35°, in particular in the range from 20° to 30°.

[0066] The support element 2 has a first support element side stop surface 15 and a second support element side stop surface 16. The bearing element 3 has a first bearing element side stop surface 17 and a second bearing element side stop surface 18. In the initial state, the first bearing element side stop surface 17 abuts the first support element side stop surface 15, and in the pivoted state, the second bearing element side stop surface 18 abuts the second support element side stop surface 16.

[0067] Furthermore, the skibinding 1 preferably has a locking element 7 with which the bearing element 3 can be locked to the support element 2 so that pivoting between the bearing element 3 and the support element 2 is made impossible. The locking is then activated when the ski is used for a downhill run.

[0068] In the embodiment shown, the locking element 7 is provided by an opening 8 in the support element 2, an opening 9 in the bearing element 3 and a locking pin that can be pushed into the opening 8, 9. In the inserted state, the bearing element 3 is locked to the support element 2.

[0069] With reference to FIGS. 1a to 5b, the movement sequence of the skibinding 1 will now be explained in more detail.

[0070] In FIGS. 1a/1b, the skibinding 1 is shown in a standing state. The skier, in particular the ski tourer, stands with his foot flat in the skibinding 1. From the standing state, the roll process begins and the foot or the skiboot 5 moves into a pulling state, as shown in FIGS. 5a/5b.

[0071] Starting from the standing state, the skiboot 5 rolls on the convex supporting surface 6.

[0072] At the beginning of the roll process, the skiboot 5 rolls on the crowned surface 6. At the same time, a pivoting movement of the skiboot 5 about the first pivot axis S1 is executed or caused due to the connection between the skiboot 5 and the skiboot reception 4, respectively. Also simultaneously, a pivoting movement of the bearing element 3 about the second pivot axis S2 is effected or executed, respectively, whereby the bearing element 3 is pivoted from its initial state with respect to the support element 2 in the direction of its pivoted state. In other words, the tip 22 of the skiboot 5, pushes down the skiboot reception 4, resulting in said pivoting movements.

[0073] In the standing state, the first pivot axis S1 and the second pivot axis S2 span a reference plane E. When moving into the pulling state, the first pivot axis S1 is moved away from this reference plane E and back towards this reference plane E again. The reference plane E is substantially parallel to the underside of the base plate or substantially parallel to the surface of the ski on which the support element 2 is mounted, respectively. If the skier uses a climbing aid, the reference plane E can also run at an angle to the underside of the base plate or at an angle to the surface of the ski on which the support element 2 is mounted, respectively.

[0074] FIGS. 2a/2b show very clearly how the skiboot 5 rolls on the convex supporting surface 6. The contact point between the skiboot 5 and the convex supporting surface moves towards the support element 2 as the roll process progresses from the standing state. At the same time, the skiboot 5 is further pivoted about the first pivot axis S1 relative to the bearing element 3. Also at the same time, the bearing element 3 is pivoted about the second pivot axis S2 relative to the support element 2, whereby the first pivot axis S1 is pivoted about the second pivot axis S2.

[0075] When the skiboot 5 moves into the pulling state, the skiboot 5 performs a pivoting movement about the first pivot axis S1 and the bearing element 3 and the first pivot axis S1 perform a pivoting movement about the second pivot axis S2. In the process, the boot reception 4 is pivoted downward with the first pivot axis S1 with respect to the second pivot axis S2 toward the support element 2. That is, the first pivot axis S1 is pivoted towards the upper side of a ski.

[0076] FIGS. 3a/3b show a state between the standing state and the pulling state. In the state shown, which can also be referred to as the intermediate state, the roll process between the convex supporting surface 6 and the skiboot 5 is completed. Likewise, the pivoting movement about the second pivot axis S2 is completed. The second bearing element side stop surface 18 abuts the second support element side stop surface 16, whereby the bearing element 3 is abuts the support element 2. In the state shown, the maximum pivot angle of the bearing element 3 relative to the support element 2 has been reached. The pivot angle is indicated by the reference sign cc in FIG. 3b.

[0077] Starting from the state shown in FIGS. 3a/3b, the skiboot 5 is now moved further in the direction of the pulling state. In the process, the skiboot 5 is pivoted further relative to the bearing element 3 about the first pivot axis. The skiboot 5 is further pivoted in the same pivoting direction as from the initial state into the intermediate state relative to the pivot mount 4. At the same time, a movement of the bearing element 3 takes place. In a first phase of the further movement into the pulling state, the bearing element 3 continues to abut the support element 2 in the pivoted state. In a second phase of the movement into the pulling state, the bearing element 3 is pivoted back to its initial state with respect to the support element, with the bearing element 3 resting with its first bearing element side stop surface 17 against the first support element side stop surface 15.

[0078] FIGS. 5a/5b show the pulling state. In the pulling state, the actual roll process of the skiboot 5 is completed and the skier will pull the ski accordingly. The bearing element 3 and also the skiboot 5 are then moved back to the standing state.

[0079] With this sequence of movements, in particular also due to the movement limitations at the stops, typical necessary movements such as sharp turns or short descents can also be executed without locking the heel, in a stable manner and without an unsteady standing feeling of the skier.
