Description

technical field

The present invention relates to a ski binding, in particular a touring ski binding, comprising a support element that can be fastened to the ski and a bearing element with a ski boot mount, which ski boot mount is designed in such a way that the ski boot can be mounted in the ski boot mount so that it can pivot about a first pivot axis with respect to the ski boot mount, and an arrangement comprising a ski binding according to the invention and a ski boot, the tip of the ski boot having a bearing point for the pivotable connection to the ski boot mount.

State of the art

Touring ski bindings are known from the prior art. For an ascent, the touring ski binding can be adjusted in such a way that the ski boot is only connected to the touring ski binding at the toe of the boot. The heel is free to move with respect to the surface of the ski. The heel is again fixed for a descent.

From the pamphlet DE 202 08 913 U1 a touring ski binding has become known, which is intended to allow natural rolling during ascent. The touring ski binding has a base plate for this purpose. The base plate is connected to a first hinge at the front. The hinge is connected to a plate, which in turn is connected to a support element by another hinge. The support element is below the base plate. Because of this design, the movement of walking is interrupted when the pivoting movement around the other hinge has taken place and the plate stands up on the ski and then begins the pivoting movement around the first hinge.

Furthermore, there is the disadvantage that the technical implementation leads to a mechanism which reproduces an inaccurate, backlash-prone behavior and is also very error-prone.

A (fictitious) ski is often used as a reference system for the description of ski bindings, whereby it is assumed that the binding is mounted on this ski. This habit is adopted in the present text. In this reference system, the term "ski longitudinal direction" means along the orientation of the longitudinal axis of the ski. Similarly, for an elongated object, "ski-parallel" means aligned along the longitudinal axis of the ski. For a flat object, on the other hand, the term "parallel to the ski" means aligned parallel to the sliding surface of the ski. Furthermore, the term "ski transverse direction" means a direction transverse to the longitudinal direction of the ski, which, however, does not have to be oriented exactly at right angles to the longitudinal axis of the ski. Their orientation can also deviate slightly from a right angle. The term "ski center" in turn means a center of the ski viewed horizontally in the transverse direction of the ski, while the term "ski-fixed" means not movable relative to the ski. It should also be noted that terms that do not contain the word "ski" also refer to the reference system of the (fictitious) ski. The terms "front", "rear", "top", "bottom" and "side" refer to "front", "back", "top", "bottom" and "side" of the ski. Likewise, terms such as "horizontal" and "vertical" also refer to the ski, with "horizontal" meaning lying in a plane parallel to the ski and "vertical" meaning perpendicular to this plane.

Presentation of the invention

Proceeding from this state of the art, the invention is based on the object of specifying a ski binding, in particular a touring ski binding, which enables an improved movement sequence when climbing.

This object is achieved by the subject matter of claim 1. Accordingly, a ski binding, in particular a touring ski binding, comprises a support element which can be fastened to the ski, a bearing element with a ski boot mount which is designed in such a way that the ski boot can be mounted in the ski boot mount so that it can be pivoted about a first pivot axis with respect to the ski boot mount or is stored, and a convex bearing surface on which the ski boot can roll off. The bearing element is connected to the support element such that it can pivot about a second pivot axis from an initial position into a pivot position. The ski boot can be moved from a stationary position, in which the ski boot stands up on the crowned bearing surface, into a pulling position, in which the ski boot is at least partially lifted off the crowned bearing surface. Starting from the stationary position, the ski boot can be moved on the convex contact surface in the direction of the pulling position in such a way that the ski boot rolls on the convex contact surface. At the same time as the rolling process, the rolling process causes a pivoting movement of the ski boot about the first pivot axis and a pivoting movement of the bearing element about the second pivot axis.

The arrangement of the two pivot axes and the convex contact surface has the advantage that the ski boot can be guided using a very ergonomic movement sequence. This sequence of movements preferably also approaches the natural barefoot walking that people prefer, even with a rigid ski boot. In particular, a dynamic and fluid movement, in particular also of the entire body of the skier, can be achieved, which can be carried out without interrupting the movement. This sequence is more like normal walking with a fluid movement of the upper body. With binding concepts known from the prior art, the foot usually has to be put down when climbing uphill or running on level ground before the weight can be shifted and the next step can be taken. This leads to a rather jerky or stop-and-go movement of the skier being observed. The rolling according to the invention allows the hips and upper body to be moved with far fewer decelerations and accelerations and can thus be moved more fluently and thus with less effort. This noticeably reduces not only the muscular loads but also the loads on the skier's joints and ligaments.

As mentioned, the skier moves the ski boot from the standing position to the pulling position. The standing position is the position in which the skier stands firmly on the ski. With the optional use of a climbing aid, an additional distance between the heel and the ski can be created in the standing position, with the front part of the ski boot still on the bearing surface rests. The rolling process is then shortened compared to the rolling process without a climbing aid, with the movements of the pivot axes taking place analogously. The pull position is the position in which the skier pulls the ski forward to take the next step with the ski. In the pulling position, the ski is pulled while hanging on the boot. In the pulling position, the ski boot is lifted at the heel and at least partially from the convex contact surface. At least partially lifted is to be understood as meaning that the ski boot is partially or completely lifted from the convex contact surface.

A convex bearing surface is a bearing surface which is designed in such a way that a rolling process can be provided. Preferably, the convex bearing surface is convexly curved with a radius of curvature about an axis of curvature. The axis of curvature runs parallel to said pivot axes. The convex bearing surface can have the same radius of curvature everywhere or different radii of curvature depending on the position on the convex bearing surface. In addition, the position of the axis of curvature can also change depending on the position on the bearing surface. Irrespective of this, the convex bearing surface is preferably convexly curved.

The movement of the ski boot from the stationary position and the starting position of the bearing element into the pulling position is preferably guided exclusively via the convex contact surface and via the first pivot axis and the second pivot axis. If the ski boot lifts completely from the convex contact surface, the movement is guided exclusively via the first pivot axis and the second pivot axis.

As mentioned, when the ski boot moves in the direction of the pulled position, the ski boot performs a pivoting movement about the first pivot axis and the bearing element performs a pivoting movement about the second pivot axis. The ski boot mount is pivoted downwards with the first pivot axis with respect to the second pivot axis toward the support element or toward the ski. The movement in the direction of the drawing position is therefore such that the tip of the ski boot is moved down towards the ski.

The pivoting movement about the first pivoting axis preferably takes place in a different pivoting direction than the pivoting movement about the second pivoting axis.

The second pivot axis is preferably located on the support element in such a way that its distance from the ski on which the support element is mounted is fixed.

During the movement of the ski boot into the pulling position, after the ski boot has reached an intermediate position, the bearing element rests firmly against the support element in its pivoting position in a first phase of the movement between the intermediate position and the pulling position and is pivoted back into its starting position in a second phase of said movement. In other words, the bearing element rests firmly on the support element in the intermediate position, particularly in its pivoted position on the support element, and is then pivoted away from the support element again as the ski boot moves further into the pulled position. In the intermediate position, the bearing element is thus in its pivoted position.

The first pivot axis preferably runs parallel to the second pivot axis and the first pivot axis can be pivoted about the second pivot axis. The position of the second pivot axis is fixed relative to the support element or to the ski. The maximum pivoting angle α of the first pivoting axis about the second pivoting axis is preferably in the range from 10° to 35°, in particular in the range from 20° to 30°. In other words, the first pivot axis can be pivoted about the second pivot axis by this maximum pivot angle. Preferably, the first pivot axis lowers in the direction of the ski during the course of movement of a step. Advantageously, when the bearing element pivots about the second pivot axis, the first pivot axis can be lowered by at least 10 mm, particularly advantageously by at least 15 mm, toward the ski. The first pivot axis can preferably be moved away from the ski by a pivoting movement of the bearing element about the second pivot axis by at least 10 mm, particularly advantageously by at least 15 mm, starting from the pivot position of the bearing element.

The maximum pivoting angle of the ski boot about the first pivoting axis is preferably greater than the maximum pivoting angle of the first pivoting axis about the second pivot axis. In a variant of this, however, there is also the possibility that the maximum pivoting angle of the ski boot about the first pivoting axis is the same as the maximum pivoting angle of the first pivoting axis about the second pivoting axis or smaller than the maximum pivoting angle of the first pivoting axis about the second pivoting axis.

The first and/or second pivot axis may be provided by a physical axis in the shape of a cylinder. Alternatively, the first and/or the second pivot axis can also be produced by a flexible element such as a spring plate, a rubber part or a belt strap. The mobility can also result approximately like a fixed axis of rotation.

The two pivot axes preferably remain parallel to one another throughout the movement from the stationary position to the starting position.

The first pivot axis and the second pivot axis preferably span a reference plane in the stationary position. The first pivot axis is moved away from this reference plane and moved back to this reference plane before reaching the drawing position. In other words, during the movement from the stationary position to the pulling position, the first pivot axis is deflected out of the reference plane and then moved back in the direction of the reference plane. It is irrelevant whether the first pivot axis is located below the reference plane, in the reference plane or above the reference plane when the drawing position is reached.

The reference plane runs essentially parallel to a mounting surface of the support element, with which the support element can be mounted on the surface of a ski. In the installed position, the reference plane is preferably essentially parallel to the surface of the ski on which the ski binding is mounted on the ski. When using a climbing aid, the reference plane runs at an angle to the mounting surface or to the surface of the ski.

The first pivot axis preferably provides an articulated joint between the ski boot and the ski boot mount.

When climbing, a climbing aid in the standing position can preferably support the heel in an elevated manner relative to the ski.

The first pivot axis preferably lies between the second pivot axis and the ski boot.

Both axes preferably move simultaneously in such a way that the point of contact between the ski boot and the contact surface is without sliding movement and therefore without wear and tear. In other words, the ski boot rolls on the support surface in the sense of a rolling movement, without a sliding movement being able to occur between the ski boot and the support surface.

The ski binding preferably also has a locking element with which the bearing element can be locked in relation to the support element, in particular in a downhill position relative to the support element, so that pivoting between the bearing element and the support element is made impossible. The ski boot can therefore not be moved into the pulling position. The ski binding can be fixed for descents by locking, so that the tip and heel of the ski boot are rigidly fixed. The departure position of the bearing element can correspond to the initial position described above or deviate from the initial position described above. In an advantageous variant, the bearing element is connected to the support element so that it can be pivoted about the second pivot axis from the downhill position to the pivoted position, with the bearing element being moved during a continuous pivoting movement from the downhill position to the pivoted position, first to the starting position and from the starting position to the pivoted position becomes. This means that the starting position is preferably between the downhill position and the pivoting position. This has the advantage that the first pivot axis is further away from the ski in the downhill position than in the starting position. As a result, the ski binding can be fixed for descents by means of the locking device in such a way that the toe and the heel of the ski boot are rigidly fixed and the ski boot is held in the ski binding above the convex contact surface. This has the advantage that the ski binding can be used for different ski boots without further adjustments. The reason for this is that, depending on the shape of the ski boot, in the standing position of the ski boot, in which the ski boot rests on the convex contact surface stands up, the distance between the first pivot axis and the ski can vary. Depending on the shape of the ski boot, the first pivot axis can therefore be at a different height above the ski in the initial position. By providing a downhill position in which the first pivot axis is further away from the ski than in the starting position, it is ensured that the ski binding for all common ski boots allows the ski boot to be in a standing position in which the ski boot rests on the convex contact surface, and at the same time with the downhill position for all common ski boots in a simple way allows a rigid fixation of the tip and heel of the ski boot. In this variant, the first pivot axis can advantageously be moved away from the ski to the downhill position by pivoting the bearing element about the second pivot axis by at least 10 mm, particularly advantageously by at least 15 mm, starting from the pivot position of the bearing element.

The locking element is preferably provided by an opening in the support element, an opening in the bearing element and a locking bolt which can be pushed into the openings, the bearing element being locked to the support element when the locking bolt is pushed in. In a preferred variant, on the other hand, the locking element is an element that can be displaced in the bearing element, with the locking element being able to be displaced into a position in which it is supported on the support element, as a result of which the bearing element is locked in relation to the support element. The ski tourer can lock the ski binding with a very simple element for the descent. Alternatively, this can also be done by a frictional or form-fitting element such as a clamping device or a blocking element.

The support element preferably has a base plate from which two bearing blocks which are spaced apart from one another protrude. The bearing blocks have the bearing points for the pivotable mounting of the bearing element relative to the support element. The bearing element extends in between the two bearing blocks. The base plate can be formed, for example, by a metal plate whose upwardly bent ends form the two bearing blocks. However, the support element can also have other elements such as an insert element.

The base plate preferably has a mounting surface on the underside, with which the support element can be mounted on the surface of a ski.

The base plate preferably has a large number of fastening openings. The fastening openings are used to hold fastening screws with which the support element can be firmly connected to a ski.

Preferably, the bearing blocks extend from an upper surface of the base and lie on two opposite side edges of the base.

Preferably, each of the bearing blocks has a bearing opening. A bearing pin extends through the bearing openings. The bearing element is mounted on said bearing bolt. The bearing pin defines the second pivot axis.

The bearing bolt is preferably firmly connected to the bearing element. The bearing bolt and the bearing openings form a plain bearing, with the bearing bolt being pivotable accordingly in the plain bearing. Alternatively, the bearing bolt is fixedly mounted in the opening and the bearing element is designed to be pivotable relative to the bearing bolt.

In every position, the ski boot holder preferably lies outside the space between the two bearing blocks.

The support element preferably has a first stop surface on the support element side and a second stop surface on the support element side. The bearing element has a first abutment surface on the bearing element side and a second abutment surface on the bearing element side, wherein in the starting position the first abutment surface on the bearing element side abuts the first abutment surface on the support element side and the second abutment surface on the bearing element side abuts the second abutment surface on the support element side in the pivoted position. In a variant of this, however, there is also the possibility that the first stop surface on the bearing element side does not contact the first stop surface on the support element side in the initial position, while the second stop surface on the bearing element side contacts the second stop surface on the support element side in the pivoted position. In a preferred variant is the first abutment surface on the bearing element side in the previously described downhill position on the first abutment surface on the support element side, while in the pivoting position the second abutment surface on the bearing element side abuts against the second abutment surface on the support element side.

In one variant, the convex bearing surface is provided by a convex upper side of a base plate. In a further variant, the convex contact surface is provided by a convex underside of the ski boot. In a further variant, the convex contact surface is provided by a convex upper side of the base plate and by a convex underside of the ski boot. The crowning can also be provided approximately, for example, by a stepped contour. In another variant, the sole of the ski boot and the surface of the base plate can each have a contour, with the two contours interlocking. In this variant, the contour can provide the crowning. The contour can further increase lateral stability for the ski boot.

Preferably, the bottom plate is mounted on the top of the ski. The base plate is preferably matched to other elements of the ski binding in terms of contour and height. The contour and the height of the base plate can also be matched to the crown of the ski boot. The base plate can also be firmly connected or integrated into the ski. If the underside of the ski boot is convex, the base plate can also be designed to be flat.

The base plate is preferably designed separately from the support element. However, the base plate can also be an integral part of the support element.

Irrespective of whether the base plate is formed separately from the support element or whether the base plate is an integral part of the support element, the base plate preferably has a crampon holding device for attaching and holding a crampon to the base plate. The base plate preferably comprises a base element that can be fastened to the ski and a cover element that can be fastened to the base element, with the cover element being movable into a cover layer in which a contact surface of the cover element is aligned in such a way that the ski boot held in the ski binding is supported downwards on the contact surface can, whereby that The cover element is movable away from the cover layer, in particular into a cover layer, wherein when the cover element is moved away from its cover layer, in particular into the cover layer, the crampon is attachable to the crampon holding device in order to be held by the crampon holding device. Advantageously, the crampon can be attached to the crampon holding device in such a way that a surface of the crampon is positioned essentially at the same position as the contact surface of the cover element in the cover layer in order to support the ski boot held in the ski binding downwards on the surface.

This has the advantage that by moving the cover element away from the cover layer, the bearing surface of the cover element can be moved away and the space occupied by the cover element in the cover layer is released. As a result, this space can be occupied by a crampon held in the crampon holding device. Accordingly, when the cover member is moved away from the cover sheet, the surface of the crampon can replace the bearing surface of the cover member and serve to support the ski boot held in the ski binding down on the surface of the crampon. As a result, a very compact construction of the ski binding can be achieved.

This advantage can also be achieved with ski bindings other than those described above as the ski binding according to the invention. Therefore, in a further invention, which can be used independently of the ski binding described above and below, a ski binding is provided, which ski binding has a base plate, the base plate having a crampon holding device for attaching and holding a crampon to the base plate, the base plate having a comprises a base element that can be fastened to the ski and a cover element that can be fastened to the base element, with the cover element being movable into a cover layer in which a contact surface of the cover element is aligned in such a way that the ski boot held in the ski binding can be supported downwards on the contact surface, with the cover element away from the cover layer, in particular into a cover layer, wherein when the cover element is moved away from its cover layer, in particular into the cover layer, the crampon can be attached to the crampon holding device is to be held by the crampon holding device. Advantageously, the crampon can be attached to the crampon holding device in such a way that a surface of the crampon is positioned essentially at the same position as the contact surface of the cover element in the cover layer in order to support the ski boot held in the ski binding downwards on the surface.

A ski binding according to this further invention as well as a ski binding of the invention described at the outset can have one or more of the following further base plates.

The crampon holding device is advantageously arranged on the base element. This has the advantage that the ski binding can be constructed in a particularly simple manner. In a variant of this, however, there is also the possibility that the crampon holding device is arranged on another element of the base plate, for example on the cover element.

In the context of the initially mentioned ski binding with the convex contact surface, the contact surface of the cover element in the top layer of the cover element advantageously forms at least one area of the convex contact surface. However, it is not necessary for the contact surface of the cover element to form at least one area of the convex contact surface in the cover layer of the cover element.

The cover element is preferably movably mounted on the base element, in particular adjustable from the cover layer into the cover layer and back. The cover element is particularly preferably mounted on the base element so that it can be adjusted from the cover layer into the cover layer and back. This has the advantage that the cover element is always mounted on the base element and therefore cannot be lost. Alternatively, there is also the possibility that the cover element can be removed from the base element and attached to the base element in the cover layer. In a preferred variant, the cover element is mounted on the base element so that it can pivot about an axis. The cover element is particularly preferably mounted on the base element such that it can be pivoted about the axis from the cover layer into the cover layer and back. This has the advantage that the cover element can be mounted adjustably on the base element in a simple and stable manner.

In a further preferred variant, the cover element is mounted on the base element in a displaceable manner, in particular displaceable in the longitudinal direction of the ski. Particularly preferably, the cover element is mounted on the base element so that it can be moved from the top layer into the cover layer and back, in particular in the longitudinal direction of the ski. This has the advantage that the cover element only requires a very small amount of space for adjustment.

The bearing element preferably has two bearing sections, which bearing sections extend away from the bearing element, particularly preferably away from the second pivot axis, in particular radially away from the second pivot axis, the bearing sections being spaced apart from one another in such a way that an intermediate space is created between the bearing sections is, in which the ski boot can protrude and the ski boot mount is provided at the free end of the bearing sections, the ski boot mount. Each free end preferably has a pin which can engage in a corresponding bearing point on the ski boot.

The two bearing sections are preferably mechanically firmly coupled to one another. The coupling is such that the two bearing sections each run parallel to one another during the movement into the drawn position.

The pins protrude from the free end of the bearing section. The two pins are arranged collinear to each other and define the first pivot axis.

In a preferred variant, the free end of the bearing sections is designed as a swivel arm with a joint, which swivel arm can be swiveled relative to the bearing section. The swivel arm is preferably designed in such a way that it is locked in a normal position and releases the shoe in the event of a safety opening in the event of a fall or other overload.

In a further preferred variant, the bearing sections are mounted so as to be displaceable essentially horizontally in the transverse direction of the ski relative to one another, in particular in a body of the bearing element. Preferably, the two bearing sections can be locked in a holding position, which can also be referred to as the normal position. In this holding position, the pins are preferably arranged at a distance from one another, so that a ski boot can be held by the pins in its toe region so that it can be pivoted about the pins and thus about the first pivot axis. Starting from this stop, the two pins can preferably be moved apart into a release position, in that the bearing sections are moved apart horizontally in the transverse direction of the ski.

Preferably, the ski binding also includes a heel locking element, which is arranged behind the support element in the direction of travel of the ski. The rear area of the ski boot can be locked to the ski with the heel locking element.

An arrangement comprises a ski boot and a ski binding as described above, the tip of the ski boot having a bearing point for pivotable connection to the ski boot mount.

Preferably, the bearing point at the tip of the ski boot is a socket for receiving said pin, which is arranged on the ski boot socket.

The arrangement can also include a ski, with the ski binding being attached to the ski with the support element. The expression ski can be understood to mean an alpine ski, a touring ski, a cross-country ski, a telemark ski or a ski part of a snowboard in a divisible design.

Further embodiments are specified in the dependent claims.

Ways to carry out the invention

In the Figures 1a to 5b a ski binding 1 according to the invention is shown. The ski binding is preferably a touring ski binding, an alpine ski binding, a telemark ski binding or a cross-country ski binding or a binding for a divisible snowboard.

The ski binding 1 comprises a support element 2 that can be fastened to the ski, a bearing element 3 with a ski boot mount 4, which is designed in such a way that the ski boot 5 is mounted in the ski boot mount 4 so that it can pivot about a first pivot axis S1 with respect to the ski boot mount 4, and a convex contact surface 6 , on which the ski boot 5 can roll. The bearing element 3 is pivotably connected to the support element 2 via a second pivot axis S2.

The support element 2 has a base plate 10 . From the top of the base plate 10, two spaced bearing blocks 11 protrude. The underside of the base plate is a mounting surface 27 which rests on the top of a ski, not shown in the figures. The mounting surface thus runs parallel to the surface of the ski.

The base plate 10 includes a plurality of bearing openings 12, via which the support element 2 can be attached to the ski. The bearing blocks 11 provide the bearing points for the pivotable mounting of the bearing element 3 . In this case, the bearing element 3 can be pivoted relative to the support element 2 . The bearing element 3 lies partly between the two bearing blocks 11. Each of the bearing blocks 11 has a bearing opening 12 in each case. The bearing openings 12 are arranged in alignment with one another. A bearing pin 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 pin 13. FIG. The bearing pin 13 defines the second pivot axis S2. In one variant, the bearing pin 13 is pivotably mounted in the bearing openings 12 and the bearing element 3 is firmly connected to the bearing pin 13 . In another variant, the bearing pin 13 is mounted firmly in the bearing openings 12 and the bearing element 3 has an opening through which the bearing pin extends in such a way that the bearing element 3 can be pivoted relative to the bearing pin 13 .

The bearing element 3 is connected to the support element 2 so that it can pivot about the second pivot axis S2 from an initial position into a pivot position. The ski boot mount 4 is outside the space between the two bearing blocks 11.

As already explained, the bearing element 3 is designed with a ski boot mount 4 . In the embodiment shown, the bearing element 3 has two bearing sections 24 , which bearing sections 24 extend away from the bearing element 3 . In a preferred variant, the two bearing sections extend away from the second pivot axis S2, in particular radially away from the second pivot axis S2. In the embodiment shown, the two bearing sections 24 extend away from the bearing pin 13 . The two bearing sections 24 are spaced apart from one another in such a way that an intermediate space is created between the bearing sections 24 . The ski boot 5 can protrude into this intermediate space. The ski boot mount 4 is also located at the free end of the bearing sections 24 . The two pins 25 run in the same axis and engage in bearing points 23 on the ski boot 5 . The pins 25 and the engagement in the bearing points 23 define the first pivot axis S1. The bearing section 24 also has a joint 26 , the free end being pivotable about the joint 26 so that the pin 25 can engage in the bearing points on the ski boot 5 via the joint 26 . The joint 26 and/or the bearing section 24 is preferably blocked for the movement from the stationary position to the pulling position, so that the ski binding cannot open.

The convex contact surface 6 on which the ski boot 5 can roll is provided in the embodiment shown by a base plate 20 with a convex upper side 19 and by a convex underside 21 of the ski boot 5 . The ski boot 5 can roll on the convex contact surface 6.

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 α about the second pivot axis S2. The maximum pivoting angle α of the first pivoting axis S1 about the second pivoting axis S2 is preferably in the range from 10° to 35°, in particular in the range from 20° to 30°.

The support element 2 has a first stop surface 15 on the support element side and a second stop surface 16 on the support element side. The bearing element 3 has a first stop surface 17 on the bearing element side and a second stop surface 18 on the bearing element side. In the starting position, the first stop surface 17 on the bearing element side contacts the first stop surface 15 on the support element side, and in the pivoted position, the second stop surface 18 on the bearing element side contacts the second stop surface 16 on the support element side.

Furthermore, the ski binding 1 preferably has a locking element 7 with which the bearing element 3 can be locked in relation to the support element 2 so that pivoting between the bearing element 3 and the support element 2 is made impossible. The lock is activated when the ski is used for a descent.

In the embodiment shown, the locking element 7 is through an opening 8 in the support element 2, an opening 9 in the bearing element 3 and a locking bolt in the Opening 8, 9 can be inserted provided. When pushed in, the bearing element 3 is locked to the support element 2 .

Based on Figures 1a to 5b the sequence of movements of the ski binding 1 will now be explained in more detail.

In the Figures 1a/1b the ski binding 1 is shown in a standing position. The skier, in particular the ski tourer, stands with his foot flat in the ski binding 1. From the standing position, the rolling process begins and the foot or ski boot 5 moves into a pulling position, as in FIG Figures 5a/5b shown.

Starting from the standing position, the ski boot 5 rolls on the convex contact surface 6 .

At the start of the rolling process, the ski boot 5 rolls on the convex surface 6 . At the same time, a pivoting movement of the ski boot 5 about the first pivot axis S1 is carried out or caused by the connection between the ski boot 5 and the ski boot mount 4 . Also at the same time, a pivoting movement of the bearing element 3 about the second pivot axis S2 is brought about or executed, with the bearing element 3 being pivoted from its initial position with respect to the support element 2 in the direction of its pivot position. In other words, the tip 22 of the ski boot 5 presses the ski boot mount 4 down, which results in said pivoting movements.

In the stationary position, the first pivot axis S1 and the second pivot axis S2 span a reference plane E. During the movement into the drawing position, the first pivot axis S1 is moved away from this reference plane E and is moved back towards this reference plane E. The reference plane E runs essentially parallel to the underside of the base plate or essentially parallel to the surface of the ski on which the support element 2 is mounted. 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.

In the Figures 2a/2b can be seen very well how the ski boot 5 rolls on the convex contact surface 6. The contact point between the ski boot 5 and the convex contact surface moves from the stationary position with increasing degree of the rolling process viewed towards support element 2. At the same time, the ski boot 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, as a result of which the first pivot axis S1 is pivoted about the second pivot axis S2.

When the ski boot 5 moves into the pulling position, the ski boot 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. The shoe mount 4 is pivoted downwards towards the support element 2 with the first pivot axis S1 in relation to the second pivot axis S2. This means that the first pivot axis S1 is pivoted towards the top of a ski.

In the Figures 3a/3b a position between the stand position and the draw position is shown. In the position shown, which can also be referred to as an intermediate layer, the rolling process between the convex contact surface 6 and the ski boot 5 is complete. The pivoting movement about the second pivot axis S2 is also completed. The second stop surface 18 on the bearing element side is in contact with the second stop surface 16 on the support element side, as a result of which the bearing element 3 is firmly in contact with the support element 2 . In the position shown, the maximum pivoting angle of the bearing element 3 relative to the support element 2 has been reached. The swivel angle is in the Figure 3b with the reference symbol α.

Starting from the in the Figures 3a/3b position shown, the ski boot 5 is now moved further in the direction of the drawing position. The ski boot 5 is pivoted further relative to the bearing element 3 about the first pivot axis. The ski boot 5 is pivoted further in the same pivoting direction as from the starting position to the intermediate position relative to the pivot mount 4 . At the same time, there is a movement of the bearing element 3. In a first phase of the further movement into the drawing position, the bearing element 3 is still firmly attached to the support element 2 in the pivoted position. In a second phase of the movement into the drawing position, the bearing element 3 is pivoted back into its initial position with respect to the support element, the bearing element 3 with its first stop surface 17 on the bearing element side against the first stop surface 15 on the support element side.

In the Figures 5a/5b the drawing position is shown. In the pulling position, the actual rolling process of the ski boot 5 is complete and the skier will pull the ski accordingly. The bearing element 3 and also the ski boot 5 are then moved back into the stationary position.

With this sequence of movements, in particular also due to the movement limitations at the stops, typical necessary movements such as kick turns or short descents can also be carried out stably and without the skier feeling unsteady without locking the heel.

In the Figures 6 to 10b a further ski binding 101 according to the invention is shown, which is a touring ski binding. Here is in the Figures 6 to 10b only the front unit of the ski binding 101 is shown in each case. However, the ski binding 101 also includes a heel locking element, which is arranged behind the support element 102 and behind the base plate 120 in the direction of travel of the ski. The rear area of the ski boot can be locked to the ski with the heel locking element. Such heel locking elements are known. An example of such a heel locking element is in US Pat EP 3 195 906 A1 of Fritschi AG - Swiss Bindings as described. In the in the EP 3 195 906 A1 the heel locking element is referred to as a heel unit.

In the figure 6 an exploded representation in an oblique view of the ski binding 101 is shown. Based on this representation, the elements of the ski binding 101 are explained, which elements in the Figures 1a to 5b shown ski binding 1 correspond. At the same time, however, deviations in the Figures 6 to 10b shown ski binding 101 to the Figures 1a to 5b shown ski binding explained. Subsequently, in connection with Figures 7a to 10b the functioning of the ski binding 101 is explained in more detail.

The in the Figures 6 to 10b Ski binding 101 shown comprises a support element 102 that can be fastened to the ski and a bearing element 103 with a ski boot mount 104, which is designed such that a ski boot, not shown here, with respect to the Ski boot holder 104 can be mounted in the ski boot holder 104 so that it can pivot about a first pivot axis S101. The ski binding 101 also includes a convex contact surface 106 on which the ski boot can roll. The bearing element 103 is pivotably connected to the support element 102 via a second pivot axis S102.

The support element 102 has a base plate 110 and an insert element 130 . This base plate 110 is formed by a metal plate whose ends are bent upwards and form two bearing blocks 111. The bearing blocks 111 thus protrude from the upper side of the base plate 110 at a distance from one another. The underside of the base plate 110 forms a mounting surface 127 which rests on the top of a ski, not shown in the figures. The mounting surface 127 thus runs parallel to the surface of the ski. The insert element 130 is arranged between the two bearing blocks 111 on the base plate 110 . The base plate 110 and the insert element 130 each comprise a plurality of openings for passing through fastening screws, via which the support element 102 can be fastened to the ski. The fastening screws are first guided through one of the openings in the insert element 130 and then through one of the openings in the base plate 110 before they are screwed into the ski.

The bearing blocks 111 provide the bearing points for the pivotable mounting of the bearing element 103 . As a result, the bearing element 103 can be pivoted relative to the support element 102 . The bearing element 103 lies partly between the two bearing blocks 111. Each of the bearing blocks 111 has a bearing opening 112 in each case. The bearing openings 112 are arranged in alignment with one another. A bearing pin 113 extends through the two bearing openings 112 and the space between the two bearing blocks 111. The bearing element 103 is mounted on the bearing pin 113. FIG. The bearing pin 113 defines the second pivot axis S102. In one variant, the bearing pin 113 is pivotably mounted in the bearing openings 112 and the bearing element 103 is firmly connected to the bearing pin 113 . In another variant, the bearing pin 113 is firmly seated in the bearing openings 112 and that Bearing element 103 has an opening through which the bearing pin extends in such a way that the bearing element 103 can be pivoted relative to the bearing pin 113 .

The bearing element 103 can be pivoted about the second pivot axis S102 from a downhill position to a pivoted position with the support element 102, wherein the bearing element 103 can be moved during a continuous pivoting movement from the downhill position to the pivoted position first into an initial position and from the initial position further into the pivoted position is. This means that the starting position is between the downhill position and the pivoting position. The ski boot mount 104 is located outside the space between the two bearing blocks 111.

As already explained, the bearing element 103 is designed with a ski boot mount 104 . In the embodiment shown, the bearing element 103 has two bearing sections 124, which bearing sections 124 extend away from the bearing element 103 and from the second pivot axis S102. The two bearing sections 124 thus extend away from the bearing pin 113 . The two bearing sections 124 are spaced apart from one another in such a way that an intermediate space is created between the bearing sections 124 . The ski boot can protrude into this intermediate space. The ski boot mount 104 is also located at the free end of the bearing sections 124 . The two pins 125 run on the same axis and engage in bearing points on the ski boot when the ski boot is held in the ski binding 101 . The pins 125 and the engagement in the bearings define the first pivot axis S101, which in the figure 6 is shown as a dotted line. The bearing sections 124 are mounted in a body of the bearing element 103 so that they can be displaced horizontally in the transverse direction of the ski. This allows the pins 125 to be moved apart into a step-in position. In this step-in position, the two pins 125 are moved far enough apart that the tip of the ski boot can be guided between the pins 125 . Furthermore, the pins 125 can be moved towards each other starting from the entry position into a holding position. If the ski boot is located with its tip between the pins 125, the pins can thereby 125 engage in the bearing points on the ski boot and keep the ski boot pivotable about the first pivot axis S101. This movement of the bearing portions 124 with the pins 125 apart in the entry position and towards each other in the holding position is similar to that in FIG EP 3 566 754 A1 described by Fritschi AG - Swiss Bindings, achieved using a slider 150. For this purpose, the ski binding 101 includes the slider 150 and an elastic element 151 in the form of a spiral spring. Both the slide 150 and the elastic element 151 are arranged essentially aligned in the longitudinal direction of the ski in the body of the bearing element 103 and can accordingly be pivoted together with the bearing element 103 about the second pivot axis S102. The elastic element 151 is arranged in front of the first pivot axis S101, viewed in the longitudinal direction of the ski. The elastic element 151 is supported against the body of the bearing element 103 at the rear and against the slider 150 at the front. When the ski binding 101 is in the assembled state, the elastic element 151 is prestressed and pushes the slider 150 forward relative to the body of the bearing element 103 . In the exemplary embodiment shown here, the prestressing of the elastic element 151 is predetermined by the shape of the body of the bearing element 103 and of the slide 151 . In variants to this, however, the prestressing of the elastic element 151 can be adjusted. This can be achieved, for example, by means of a screw or a combination of a screw and a nut, as is known from the technical field of ski bindings.

The slider 150 extends below the elastic element 151 backwards to below the two bearing sections 124. The slider 150 has a third guide form below the first bearing section 124 and a fourth guide form below the second bearing section 124. Both the third form of guidance and the fourth form of guidance are both formed by grooves running diagonally laterally forward from the middle of the ski. Furthermore, the first bearing section 124 has a first guiding shape on its underside, while the second bearing section 124 has a second guiding shape on its underside. In this case, the first form of guidance is designed to complement the third form of guidance, while the second form of guidance is designed to complement the fourth form of guidance. In the assembled state of the ski binding 101, the first guide shape interacts with the third guide shape, while the second Form of leadership interacts with the fourth form of leadership. The slider 150 is thus operatively connected to the first bearing section 124 by the interaction of the first guide shape with the third guide shape and is operatively connected to the second bearing section 124 by the interaction of the second guide shape with the fourth guide shape. Thus, when the slider 150 is shifted, the first guide shape is shifted from the third guide shape and the second guide shape is shifted from the fourth guide shape. Therefore, by moving the slide 150 in a first direction forward in the longitudinal direction of the ski, the first bearing section 124 and the second bearing section 124 are moved relative to one another, whereby the first pin 125 and the second pin 125 are also moved towards one another towards their holding position . Thus, since the slider 150 is biased forward by the biased elastic member 151, the two pins 125 are biased toward each other toward their holding position.

However, the slide 150 is also operatively connected to the first bearing section 124 and the second bearing section 124 in such a way that a movement of the first bearing section 124 and the second bearing section 124 relative to one another, during which the two pins 125 are moved apart from their holding position, the slider 125 is moved in a second direction opposite to the first direction. At the same time, by moving the slider 150 in the second direction opposite to the first direction, the first bearing section 124 and the second bearing section 124 are displaced relative to one another, as a result of which the first and the second pin 125 are moved away from each other from their holding position.

As below in connection with the Figures 9a to 9d described, the bearing sections 124 can also be locked relative to the body of the bearing element 103 so that the ski binding cannot open and the ski boot can be moved from the standing position to the pulling position when walking without detaching from the ski binding 101.

The convex contact surface 106, on which the ski boot can roll, is in the Figures 6 to 10b The ski binding 101 shown is formed by a three-part base plate 120 or by the three-part base plate 120 together with a crampon 160 possibly attached to the base plate 120 . Regardless of whether the crampon is 160 attached to the bottom plate 120 or not, the bottom plate 120 is fastened to the ski behind the support element 102 by means of screws. This three-part base plate 120 has a base element 132 which is formed by a base plate 131 and a base element 163 . In the installed state, the base element 163 is arranged above the base plate 131 . The base plate 120 also has a cover element 133 . The base plate 131 and the base element 163, which together form the base element 132, each have two openings for passing through the screws. One screw at a time is passed through one of the openings in the base element 163 and then through one of the openings in the base plate 131 before it is screwed into the ski. At its rear end, the cover element 133 is mounted on the base element 132 such that it can be pivoted about an axis. When the cover element 133 is tilted forward, the cover element 133 is in a cover position. In this cover layer, a bearing surface 161 of the cover element 133 is aligned in such a way that the ski boot held in the ski binding can be supported downwards on the bearing surface 161 . When the cover element 133 is in this cover layer, the base element 132 and the contact surface 161 of the cover element 133 together form a convex upper side 119 which forms the convex contact surface 106 . The ski boot can roll on this convex contact surface 106. However, the cover element 133 can also be pivoted backwards about the axis relative to the base element 132 into a covering position. This opens access to a crampon holding device 162 formed by the base plate 131. At this crampon holding device 162, as in FIGS Figures 9a to 10b 1 illustrates a crampon 160 being attached when the cover member 133 is pivoted rearwardly relative to the base member 132 to its cover position. When the crampon 160 is attached to the crampon holding device 162 in this way, the base element 163 and a surface of the crampon 160 together form the crowned bearing surface 106 when the crampon 160 as shown in FIGS Figures 9a to 9d shown is lowered towards the ski. Thus, the crampon 160 can be attached to the crampon holding device 162 in such a way that a surface of the crampon 160 is positioned substantially at the same position as the bearing surface 161 of the cover element 133 in the cover layer, around the ski boot held in the ski binding 101 on the surface downwards to support. In a variant of the pivotable cover element 133, the cover element can also be slid on Be stored base element. For example, the cover element can be mounted on the base element so that it can be displaced from its cover layer into its cover layer in the longitudinal direction of the ski. In a further variant of this, however, there is also the possibility that the cover element in the cover layer can be attached to the base element and removed from the base element in order to release the space for attaching the crampon 160 to the crampon holding device 162 .

The first pivot axis S101 runs parallel to the second pivot axis S102 and can be pivoted about the second pivot axis S102 by a pivot angle α. The maximum pivoting angle α of the first pivoting axis S101 about the second pivoting axis S102 is 32.12° in the present exemplary embodiment. With such a pivoting movement of the first pivot axis S101 about the second pivot axis S102, the bearing element 103 is pivoted about the second pivot axis S102. In a first end position of this pivoting movement, the bearing element 103 is in the downhill position. In a second end position of this pivoting movement, the bearing element 103 is in the pivoted position. In the downhill position, the pins 125 are 19 mm higher above the ski than in the pivot position. This means that when the bearing element 103 pivots about the second pivot axis S102, the height of the pins 125 above the ski is adjusted by a maximum of 19 mm.

The Bearing element 103 in the starting position. If the ski boot is an average touring ski boot, in this starting position of the bearing element 103 the pins 125 are 16 mm higher above the ski than in the pivoted position of the bearing element 103. In addition, the pins 125 are 3 mm lower above the ski than in the downhill position of the bearing element 103. However, since different ski boots are shaped differently in their front area, the pins 125 can also be at a slightly different height above the ski in the initial position of the bearing element 103 when the respective ski boot is in the standing position. So the pins 125 in the starting position of the bearing element 103 can each after the ski boot, for example, 14 mm higher above the ski than in the pivoted position. Depending on the ski boot, the pins 125 can also be located, for example, 17 mm higher above the ski in the initial position of the bearing element 103 than in the pivoted position.

The support element 102 has a first stop surface 115 on the support element side and a second stop surface 116 on the support element side. The bearing element 103 has a first stop surface 117 on the bearing element side and a second stop surface 118 on the bearing element side. In the downhill position, the first stop surface 117 on the bearing element side contacts the first stop surface 115 on the support element side, and in the pivoting position, the second stop surface 118 on the bearing element side contacts the second stop surface 116 on the support element side. This limits the pivoting movement of the bearing element 103 about the second pivot axis S102.

Furthermore, the ski binding 101 has two locking elements 107, with which the bearing element 103 can be locked in the downhill position relative to the support element 102, so that pivoting between the bearing element 103 and the support element 102 is made impossible. This lock can be activated when the ski is used for a descent.

In the in the Figures 6 to 10b In the embodiment shown, the locking elements 107 are guided in slots 109 in the body of the bearing element 103. Because the locking elements 107 are pushed backwards in the slots 109, they project backwards beyond the body of the bearing element 103 and are supported downwards on the second stop surface 116 on the support element side. In this position, the first stop surface 117 on the bearing element side is at the same time in contact with the first stop surface 115 on the support element side. Since the first stop surface 117 on the bearing element side and the first stop surface 115 on the support element side are located in front of the second pivot axis S102, while the second stop surface 116 on the support element side are located behind the second pivot axis S102, the bearing element 103 is locked in the downhill position. In order to release this locking, the locking elements 107 can be pushed forward in the slots 109 . As a result, the pivoting movement of the bearing element 103 is released relative to the support element 102, so that the bearing element 103 can be pivoted from the downhill position to the pivot position, where the second stop surface 118 on the bearing element side is in contact with the second stop surface 116 on the support element side.

The in the Figures 6 to 10b The ski binding 101 described comprises an actuating lever 140 which is pivotably mounted on the body of the bearing element 103 about an actuating lever axis 141 aligned horizontally in the transverse direction of the ski. This actuating lever axis 141 runs through an actuating lever axis opening 142 in the actuating lever 140. Above the actuating lever axis opening 142, a release lever axis opening 145 is formed in the actuating lever 140, in which release lever axis opening 145 a release lever 143 is pivotably mounted on the actuation lever 140 about a release lever axis 144 aligned horizontally in the transverse direction of the ski. Below the actuating lever axis opening 142, a pivoting element 146 is mounted on both sides in the actuating lever 140 so that it can be pivoted about an axis aligned horizontally in the transverse direction of the ski. These two pivoting elements 146 have downward-pointing nubs below their axle bearing, with which they each engage in a recess 158 in a front region of one of the two locking elements 107 . As a result, depending on the position of the actuating lever 140 , the locking elements 107 can be displaced in the body of the bearing element 103 by a movement of the actuating lever 140 .

The ski binding 101 also includes a connecting slide 152 that can be moved below the slide 150 in the body of the bearing element 103 essentially in the longitudinal direction of the ski. This skid 153 is used to adjust the ski binding from an entry configuration, in which the pins 125 are in the entry position, to a holding configuration, in which the pins 125 are in the holding position.

At its front end, the connecting slide 152 has two upward-pointing cams 154 which, in the assembled state, extend upwards from below into recesses on an underside of the actuating lever 140 which are open towards the bottom. However, these downwardly open recesses on the underside of the actuating lever 140 cannot be seen in the figures.

When the operating lever 140 is pulled upwards with its free operating end pointing forward, the downwardly open recesses on the underside of the operating lever 140 are moved forward. As soon as the upward-pointing cams 154 of the connecting slide 152 are in contact with the rear sides of the downwardly open recesses on the underside of the actuating lever 140, the connecting slide 152 is also pulled forward together with the tread spur 153. If, on the other hand, the actuating lever 140 is moved downwards towards the ski with its free actuating end pointing forward, the downwardly open recesses on the underside of the actuating lever 140 are moved backwards. As a result, due to the upward-pointing cam 154 of the connecting slide 152, the connecting slide 152 and thus also the spur 153 are moved backwards.

In Figure 7a an oblique view of the ski binding 101 is shown in the step-in configuration. It can be seen in the illustration that the forward-pointing free actuating end of the actuating lever 140 is lowered toward the ski, while the pins 125 are in their entry position. The spur 153 is located below the pins 125 and points obliquely backwards and upwards.

In Figure 7b a cross section running vertically in the longitudinal direction of the ski through the ski binding 101 in the step-in configuration is shown. As a result, the elastic element 151 prestressed between the slide 150 and the body of the bearing element 103 can be seen. It can also be seen how the connecting slide 152 is arranged below the slide 151 so that it can be displaced in the longitudinal direction of the ski in the body of the bearing element 103 . It can be seen that the connecting slide 152 is in a rearward position in the body of the bearing element 103 .

In the in the Figures 7a and 7b The entry configuration shown is that the locking elements 107 are pushed backwards in the slots 109, project backwards beyond the body of the bearing element 103 and are supported downwards on the second stop surface 116 on the support element side. As already described, in this position of the locking elements 107 the first stop surface 117 on the bearing element side is also in contact with the first stop surface 115 on the support element side. As a result, the bearing element 103 locked in the downhill position because the first stop surface 117 on the bearing element side and the first stop surface 115 on the support element side are in front of the second pivot axis S102, while the second stop surface 116 on the support element side are behind the second pivot axis S102.

Without an external force, the ski binding 101 remains in the step-in configuration, although the elastic element 151 is clamped between the body of the bearing element 103 and the slide 150 . This is achieved in that the actuating lever 140 has a stop 156 below the actuating lever axis 143 on its rear side. This stop 156 is in the figure 6 to recognize and acts with a slide 150 arranged, also in figure 6 apparent first counterstop 157 together. In the entry configuration, the stop 156 arranged on the actuating lever 140 and the first counter-stop 157 arranged on the slide 150 are aligned with one another in such a way that the slide 150 pushed forward by the elastic element 151 exerts a force on the actuating lever 140 causes. Since the actuating lever axis 141 is mounted in the body of the bearing element 103, against which the elastic element 151 also pushes off, this means that in the step-in configuration, the elastic element 151 does not cause any torque on the actuating lever 140 and the ski binding can be moved into of the entry-level configuration remains.

As in the Figures 7a and 7b As can be seen, the release lever 143 is essentially vertically upwards in the entry configuration. As already mentioned, the release lever 143 is mounted on the actuation lever 140 such that it can pivot about the release lever axis 144 . A torsion spring is wound around the release lever axle and biases the release lever 143 relative to the body of the bearing element 103 so that its free end pointing upwards is biased backwards. In the entry configuration, however, the release lever 143 is maintained in its substantially vertical orientation because its lower end is supported on the body of the bearing member 103. This prevents the release lever 143 from being pivoted backwards by the torsion spring. In a variant of this, however, there is also the possibility that the release lever 143 is not pretensioned by a torsion spring. In In this case, the orientation of the release lever 143 can also be controlled by abutting a portion of the release lever on the body of the bearing element 103 .

When a ski boot is inserted with its toe between the pins 125 and is thereby moved downwards so that the spur 153 is pushed down by the sole of the ski boot, a locks in figure 6 recognizable stop 155 arranged on the tread spur 153 inside the body of the bearing element 103, so that the tread spur 153 is moved forward with its front underside. This pushes the connecting slider 152 forward. As a result, the actuation lever 140 is moved somewhat upwards with its free actuation end, as previously described, by the cams 154 of the connecting slide 152 pointing upwards. This rotation of the actuating lever 140 slightly upwards with its free actuating end causes the alignment of the stop 156 arranged on the actuating lever 140 to change with respect to the first counter-stop 157 arranged on the slide 150 . The result of this is that the force acting on the actuating lever 140, which is caused by the slide 150 being pushed forward by the elastic element 151 on the actuating lever 140, changes its orientation and points forward more flatly. As soon as the direction of this force is sufficiently lowered and points forward below the actuating lever axis 141, a sufficiently large torque is applied to the actuating lever 140 so that the actuating lever 140 is pivoted upwards with its free actuating end until the free actuating end is essentially horizontal facing forward.

During this rotary movement of the actuating lever 140, the two pivotally mounted on the actuating lever 140, in figure 6 recognizable pivoting elements 146 moves with. However, the two pivoting elements 146 are pivoted relative to the actuating lever 140 so that their downward-pointing nubs rotate in the recesses 158 in the front area of one of the two locking elements 107 . The locking elements 107 are therefore not displaced relative to the body of the bearing element 103 and thus remain in their locking position, in which they protrude the body of the bearing element 103 to the rear and are supported downwards on the second stop surface 116 on the support element side. This will make the Pivoting movement of the bearing element 103 relative to the support element 102 continues to be prevented and the bearing element 103 remains locked in its downhill position.

However, with the rotational movement of the operating lever 140 described above until the free operating end of the operating lever 140 points forwards essentially horizontally, the slide 150 in the body of the bearing element 103 is also pushed forwards, so that the two bearing sections 124 are moved towards one another and the two Pins 125 are moved into their holding position, in which they engage in the bearing points on the ski boot and can pivot the ski boot about the first pivot axis S101. In this position the ski binding is in a downhill configuration.

In Figure 8a an oblique view of the ski binding 101 is shown in the downhill configuration. In the downhill configuration, the bearing element 103 is locked in its downhill position, as already mentioned, due to the position of the locking elements 107 in its rear position. Accordingly, the bearing element 103 cannot be pivoted about the second pivot axis S102 relative to the support element 103 .

In the representation of Figure 8a it can be seen that in the descent configuration, the forward-facing free operating end of the operating lever 140 is pointing forward substantially horizontally while the pins 125 are in their holding position. Here, the step spur 153 is still below the pins 125. However, its rearward-pointing, free end is lowered in comparison to the entry configuration and points essentially horizontally to the rear. This is particularly in Figure 8b 1, which shows a cross section running vertically in the longitudinal direction of the ski through the ski binding 101 in the step-in configuration.

As in Figure 8b in comparison to Figure 7b As can be seen, the slide 150 and the connecting slide 152 are moved further forward in the body of the bearing element 103 in the downhill configuration than in the boarding configuration. Due to the changed position of the slider 150, the elastic element 151 is less prestressed in the downhill configuration than in the boarding configuration.

Next is in Figure 8b to recognize that the release lever 143, in contrast to the in Figure 7b entry configuration shown is aligned substantially horizontally to the rear in the downhill configuration. This is because due to the pivotal movement of the actuating lever 140 relative to the body of the bearing member 103, the release lever axis 144 is also positioned differently relative to the body of the bearing member 103. As a result, the release lever 143 is no longer supported on the body of the bearing element 103 in the same way as in the entry-level configuration. Therefore, the release lever 143 has now been pivoted by the torsion spring and points backwards with its free end. Accordingly, the release lever axis 144 is located in the downhill configuration in the front area of the release lever 143, while a middle area of the release lever 143 is supported downwards on the body of the bearing element 103 in the area of the second pivot axis S102. In addition, the free end of the release lever forms a free-standing rear area of the release lever 143. If a ski boot held in the ski binding 101 is released from the heel locking element in the forward direction in its heel area in the event of a fall of the skier and about the pins 125 and thus about the first pivot axis S101 is pivoted forwards and upwards, the toe area of the ski boot presses from a certain pivoting angle obliquely from behind upwards onto the rear area of the release lever 143. As a result, the rear area of the release lever 143 is pressed forwards and downwards. This results in the actuating lever 140 being pressed downwards via the release lever axis 144 with its forward-pointing free actuating end. As a result of the pivoting movement of the actuating lever 140 that is forced as a result, the slide 150 is pushed backwards due to the interaction of the stop 156 with the first counter-stop 157 . This rearward movement of the slider 150 results in the bearing portions 124 being moved apart and the pins 125 being moved apart from their holding position. Once the pins 125 are moved sufficiently far apart, the ski boot is released from the ski binding 101.

Starting from the downhill configuration, the ski binding 101 can be adjusted to an uphill configuration. The following is based on the Figures 9a to 9d illustrates that the ski binding 101 can be adjusted from the downhill configuration to an uphill configuration by the free operating end of the Actuating lever 140 is pulled upwards until the free operating end is pointing substantially vertically upwards. During this rotary movement of the actuating lever 140, the two pivotally mounted on the actuating lever 140, in figure 6 recognizable pivoting elements 146 moved forward. During this movement, the two pivoting elements 146 are no longer only pivoted relative to the actuating lever 140 . Rather, the locking elements 107 are now also pulled forward by the downward-pointing nubs of the pivoting elements 146, which engage in the recesses 158 in the front region of the two locking elements 107. The locking elements 107 are therefore shifted forward relative to the body of the bearing element 103 into a release position in which they no longer protrude backwards from the body of the bearing element 103 and are no longer supported downwards on the second stop surface 116 on the support element side. This now enables the pivoting movement of the bearing element 103 relative to the support element 102 from the downhill position to the pivoting position and back.

In the Figure 9a an oblique view of the ski binding 101 is therefore shown in the ascent configuration, with the bearing element 103 being in the downhill position. In the Figure 9b on the other hand, an oblique view of the ski binding is shown in the ascent configuration, with the bearing element 103 being in the pivoted position. Analogous to this is Figure 9c a cross section running vertically in the longitudinal direction of the ski through the ski binding 101 in the ascent configuration with the bearing element 103 in the downhill position is shown, while in FIG Figure 9d a cross section running vertically in the longitudinal direction of the ski through the ski binding 101 in the ascent configuration with the bearing element 103 in the pivoted position is shown.

By pulling the operating free end of the operating lever 140 upward when shifting from a descent configuration to a climbing configuration until the operating free end is pointing substantially vertically upwards, the connecting slide 152 is also pulled further forward by the operating lever 140 on the cam 154 . As in the Figures 9a to 9d it can be seen that in the ascent configuration the connecting slide 152 in the body of the bearing element 103 is correspondingly pulled further forward than in the descent configuration. Together with the connecting slide 152, the stepping spur 153, which is pivotably mounted on the connecting slide 152, is also pulled further forward. As a result, the spur 153 is drawn almost completely into the body of the bearing element 103, so that the space below the pins 125 is released for the toe area of the ski boot. Accordingly, the ski boot held in the ski binding 101 can be pivoted about the pins 125 and thus about the first pivot axis S101 without being impeded by the spur 153 in the process.

By pulling the free actuating end of the actuating lever 140 upward when adjusting from the descent configuration to an ascent configuration, the stop 156 on the actuating lever 140 is also pivoted forward. This arranged on the operating lever 140 stop 156 is proceeding in connection with the Figures 7a and 7b already mentioned and is located in the entry configuration of the ski binding 101 below the actuating lever axis 141 on the rear side of the actuating lever 140. In the ascent configuration, however, the actuating lever 140 is pivoted so far compared to the entry configuration that this stop 156 is below the actuating lever axis 141 in Ski longitudinal direction in front of the operating lever axis 141 is located. As a result, the stop 156 arranged on the actuating lever 140 abuts against a second counter-stop 159 which is arranged in the front area of the slide 150 and points to the rear. This second counter-stop 159 is shown in FIG figure 6 shown exploded view.

The stop 156 and the second counter-stop 159 are aligned with one another in the ascent configuration and interact with one another in such a way that a force acting backwards on the slide 150 causes a force on the actuating lever 140 directed in the direction of the actuating lever axis 141 . Therefore, no torque is applied to the operating lever 140 when the slider 150 is pushed or pulled rearward. This ensures that the actuating lever 140 remains in its essentially vertical orientation despite the force acting on the slide 150 and the slide 150 can no longer be moved backwards in the body of the bearing element 103 but is blocked in its position. Based on these When the slider 150 is blocked in the ascent configuration of the ski binding 101, the bearing sections 124 are also blocked, which means that the pins 125 are blocked in their holding position. Accordingly, a ski boot held in the ski binding 101 cannot unintentionally become detached from the ski binding 101 in the ascent configuration. This means that in the ascent configuration, as already described, the two bearing sections 124 are locked relative to the body of the bearing element 103, so that the ski binding cannot open and the ski boot can be moved from the standing position to the pulling position when walking without moving from to solve the ski binding 101.

As already mentioned, a crampon 160 can be attached to the base plate 120 . For this purpose, the cover element 133 can be pivoted backwards relative to the base element 132 . This opens access to the base plate 131. Since the base plate 131 forms the crampon holding device 162 for attaching a crampon 160 in its front region, the crampon 160 can therefore be attached to the base element 132 when the cover element 133 relative to the base element 132 backwards into the Cover layer is pivoted. For this purpose, the crampon 160 in a vertical orientation as shown in FIGS Figures 10a and 10b shown from the side in the transverse direction of the ski into the crampon holding device 162 in the base plate 131 . Then the crampons 160 as in the Figures 9a to 9d shown with its major surface rearwardly toward the ski, to be lowered onto the base member 132 and the cover member 133. Since when the crampon 160 is attached to the bottom plate 120 the cover element 133 is pivoted backwards into the cover position, the base element 132 and the cover element 133 have a lower height than when the cover element 133 is pivoted forwards into the cover position on the base element 132. This lower height in the covering layer can be filled with the crampon 160 so that the contact surface 161 of the crampon 160 together with the front area of the base element 132 together form the convex contact surface 106 .

In summary, it can be stated that a ski binding, in particular a touring ski binding, is specified which enables an improved sequence of movements when climbing.
