Technical area
[0001] 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 holder, which ski boot holder is designed such that the ski boot can be mounted in the ski boot holder so as to be pivotable about a first pivot axis with respect to the ski boot holder, as well as to an arrangement comprising a ski binding according to the invention and a ski boot, wherein the tip of the ski boot has a bearing point for pivotable connection to the ski boot holder. State of the art
[0002] Touring ski bindings are well-known in the art. For an ascent, the touring ski binding can be adjusted so that the ski boot is only connected to the touring ski binding at the toe. The heel can move freely relative to the surface of the ski. For a descent, the heel is again fixed.
[0003] From the publication DE 202 08 913 U1, a touring ski binding has become known that is designed to enable natural rolling during ascent. For this purpose, the touring ski binding has a base plate. 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 further hinge with a support element. The support element is located below the base plate. Due to this design, the walking movement is interrupted when the pivoting movement around the further hinge has occurred and the plate rests on the ski, and then the pivoting movement around the first hinge begins.
[0004] Furthermore, there is the disadvantage that the technical implementation leads to a mechanism that reproduces an inaccurate, play-like behavior and is also very error-prone.
[0005] Furthermore, WO 01 / 93963 A1 from Rottefella AS describes a ski binding which comprises a binding plate, a front, first engagement element on the binding side, and a rear, fourth engagement element. The ski binding further comprises an elastomer block which serves as a counter-pressure element, and fastening, actuating, and connecting elements which are assigned to the front and rear binding-side engagement elements. The fastening, actuating, and connecting elements comprise, in particular, a sliding sleeve guide for the first engagement element with a helical spring element, which is attached to the binding plate via a first pivot axis, and an actuating lever which is connected to the sliding sleeve guide via a toggle mechanism and to the binding plate via a second pivot axis. The fourth engagement element in the form of a third engagement element arranged on the ski boot can be pivoted by approximatelyThe hook, which wraps around 180°, is designed as part of a tension band that is spring-elastic in the longitudinal direction or mounted in the binding plate. The vertical adjustment of the front end of the boot sole, and thus of the axle mounted there as the second engagement element, is enabled by the sliding sleeve guide under the influence of the spring force of the helical spring element, while maintaining the engagement of the axle with the hook, which acts as the first engagement element.
[0006] When describing ski bindings, a (fictitious) ski is often used as a reference system, assuming that the binding is mounted on that ski. This practice is adopted in this text. In this reference system, the term "longitudinal ski direction" means along the orientation of the ski's longitudinal axis. Similarly, for an elongated object, "ski-parallel" means aligned along the ski's longitudinal axis. For a flat object, however, the term "ski-parallel" means aligned parallel to the ski's gliding surface. Furthermore, the term "cross-ski direction" refers to a direction perpendicular to the ski's longitudinal direction, which, however, does not have to be oriented exactly perpendicular to the ski's longitudinal axis. Its orientation can also deviate slightly from a right angle. The term "ski center," in turn, refers to the center of the ski, seen horizontally in the cross-ski direction, while the term "ski-fixed" means immovable relative to the ski.It should also be noted that even terms that do not contain the word "ski" refer to the reference system of the (fictitious) ski. For example, the terms "front," "back," "top," "bottom," and "side" refer to the "front," "back," "top," "bottom," and "side" of the ski. Likewise, terms like "horizontal" and "vertical" refer to the ski, where "horizontal" means lying in a plane parallel to the ski, and "vertical" means oriented perpendicular to this plane. Description of the invention
[0007] Based on this prior 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 during ascent.
[0008] 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 that can be fastened to the ski, a bearing element with a ski boot holder, which is designed such that the ski boot can be mounted or is mounted in the ski boot holder so as to be pivotable about a first pivot axis with respect to the ski boot holder, and a spherical support surface on which the ski boot can roll. The bearing element is connected to the support element so as to be pivotable about a second pivot axis from an initial position into a pivot position. The ski boot can be moved from a standing position in which the ski boot rests on the spherical support surface to a pulled position in which the ski boot is at least partially lifted off the spherical support surface. Starting from the standing position, the ski boot can be moved on the spherical support surface in the direction of the pulled position such that the ski boot rolls on the spherical support surface.Simultaneously with the rolling process, the rolling process causes a pivoting movement of the ski boot around the first pivot axis and a pivoting movement of the bearing element around the second pivot axis. When the ski boot moves to the pulling position, the bearing element, after reaching an intermediate position, rests firmly against the support element in the pivoting position in a first phase of the movement between the intermediate position and the pulling position, and is pivoted back to its original position in a second phase of the movement.
[0009] The arrangement of the two pivot axes and the spherical contact surface has the advantage that the ski boot can be guided through a very ergonomic movement sequence. This movement sequence preferably comes even closer to the natural barefoot walking that humans prefer, even with a rigid ski boot. In particular, a dynamic and fluid movement can be achieved, particularly of the skier's entire body, which can be performed without interruption. This movement sequence is more similar to normal walking with a fluid movement of the upper body. With state-of-the-art binding concepts, the foot usually has to be placed on the ground when climbing uphill or running on flat ground before the weight can be shifted and the next step can be performed. This leads to a rather jerky or stop-and-go movement of the skier.The innovative rolling motion allows the hips and upper body to move with far less deceleration and acceleration, allowing for more fluid and less effort. This not only significantly reduces muscular strain, but also the load on the skier's joints and ligaments.
[0010] As mentioned, the skier moves the ski boot from the standing position into the pulling position. The standing position is the position in which the skier is standing firmly on the ski. With the optional use of a climbing aid, additional distance can be created between the heel and the ski in the standing position, with the front part of the ski boot still resting on the support surface. The rolling process is then shortened compared to the rolling process without a climbing aid, with the movements of the pivot axes occurring analogously. The pulling position is the position in which the skier pulls the ski forward in order to initiate the next step with the ski. In the pulling position, the ski is pulled along while hanging from the boot. In the pulling position, the ski boot is lifted at the heel and at least partially off the crowned contact surface. At least partially lifted means that the ski boot is partially or completely lifted off the crowned contact surface.
[0011] A spherical support surface is a support surface designed to provide a rolling action. The spherical support surface is preferably convexly curved with a radius of curvature around a curvature axis. The curvature axis runs parallel to the pivot axes. The spherical support surface can have the same radius of curvature throughout or, depending on the position on the spherical support surface, different radii of curvature. Furthermore, the position of the curvature axis can also change depending on the position on the support surface. Regardless of this, the spherical support surface is preferably convexly curved.
[0012] Preferably, the movement of the ski boot from the standing position and the starting position of the bearing element to the pulling position is guided exclusively via the spherical support surface as well as the first pivot axis and the second pivot axis. If the ski boot completely lifts off the spherical support surface, the movement is guided exclusively via the first pivot axis and the second pivot axis.
[0013] As the ski boot moves toward the pulling position, the ski boot, as mentioned, pivots around the first pivot axis, and the bearing element pivots around the second pivot axis. In doing so, the ski boot holder pivots downward toward the support element or ski with the first pivot axis relative to the second pivot axis. The movement toward the pulling position is thus such that the tip of the ski boot moves downward toward the ski.
[0014] Preferably, the pivoting movement about the first pivot axis takes place in a different pivoting direction than the pivoting movement about the second pivot axis.
[0015] Preferably, the second pivot axis is located on the support element in such a way that its distance from the ski on which the support element is mounted is fixed.
[0016] As the ski boot moves into the pulling position, the bearing element, after reaching an intermediate position of the ski boot, is firmly attached to the support element in its pivoted position in a first phase of the movement between the intermediate position and the pulling position, and is pivoted back to its original position in a second phase of the movement. In other words, the bearing element is firmly attached to the support element in the intermediate position, particularly in its pivoted position, and is then pivoted away from the support element again as the ski boot moves further into the pulling position. In the intermediate position, the bearing element is thus in its pivoted position.
[0017] Preferably, the first pivot axis runs parallel to the second pivot axis, and the first pivot axis can be pivoted about the second pivot axis. The second pivot axis is fixed in terms of its position relative to the support element or to the ski. Preferably, the maximum pivot angle α of the first pivot axis about the second pivot axis is 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 this maximum pivot angle about the second pivot axis. Preferably, the first pivot axis lowers towards the ski during the movement sequence of a step. Advantageously, during a pivoting movement of the bearing element about the second pivot axis, the first pivot axis can be lowered towards the ski by at least 10 mm, particularly advantageously by at least 15 mm.Preferably, the first pivot axis can be moved away from the ski by at least 10 mm, particularly advantageously by at least 15 mm, by a pivoting movement of the bearing element about the second pivot axis, starting from the pivoting position of the bearing element.
[0018] Preferably, the maximum pivot angle of the ski boot about the first pivot axis is greater than the maximum pivot angle of the first pivot axis about the second pivot axis. In a variant, however, it is also possible for the maximum pivot angle of the ski boot about the first pivot axis to be equal to the maximum pivot angle of the first pivot axis about the second pivot axis or smaller than the maximum pivot angle of the first pivot axis about the second pivot axis.
[0019] The first and / or second pivot axes can be provided by a physical axis in the form of a cylinder. Alternatively, the first and / or second pivot axes can also be created by a bendable or flexible element such as a spring plate, a rubber part, or a webbing. In this case, the mobility can also be achieved approximately like a fixed rotation axis.
[0020] Preferably, the two swivel axes remain parallel to each other throughout the entire movement from the stationary position to the starting position.
[0021] Preferably, the first pivot axis and the second pivot axis define a reference plane in the stationary position. The first pivot axis is moved away from this reference plane and then moved back toward this reference plane before reaching the pulling 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 toward the reference plane. It is irrelevant whether the first pivot axis is below the reference plane, in the reference plane, or above the reference plane when reaching the pulling position.
[0022] The reference plane runs essentially parallel to a mounting surface of the support element, with which the support element can be mounted to 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. When using a climbing aid, the reference plane runs at an angle to the mounting surface or the surface of the ski.
[0023] Preferably, the first pivot axis provides an articulated joint between the ski boot and the ski boot holder.
[0024] When climbing, a climbing aid can preferably be used in the standing position to support the heel higher than the ski.
[0025] Preferably, the first pivot axis lies between the second pivot axis and the ski boot.
[0026] Preferably, both axes move simultaneously so that the contact point between the ski boot and the support surface is free of sliding movement and thus friction and wear. In other words, the ski boot rolls on the support surface in a rolling motion, without any sliding movement occurring between the ski boot and the support surface.
[0027] Preferably, the ski binding further comprises a locking element with which the bearing element can be locked to the support element, in particular in a downhill position, so that pivoting between the bearing element and the support element is impossible. The ski boot can therefore not be moved into the pulled position. The locking mechanism allows the ski binding to be secured for downhill skiing, so that the toe and heel of the ski boot are rigidly fixed. The downhill position of the bearing element can correspond to the previously described initial position or deviate from the previously described initial position.In an advantageous variant, the bearing element is connected to the support element so as to be pivotable about the second pivot axis from the downhill position to the pivot position, wherein the bearing element is moved first to the starting position and then from the starting position further into the pivot position during a continuous pivoting movement from the downhill position to the pivot position. This means that the starting position is preferably between the downhill position and the pivot 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 secured for downhill skiing using the locking mechanism in such a way that the toe and heel of the ski boot are rigidly fixed and the ski boot is held in the ski binding above the spherical 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, the distance of the first pivot axis from the ski can vary in the stance position of the ski boot, in which the ski boot rests on the crowned contact surface. Thus, the first pivot axis can be at a different height above the ski in the starting position, depending on the shape of the ski boot. 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 allows a stance position of the ski boot for all common ski boots, in which the ski boot rests on the crowned contact surface, and at the same time, with the downhill position for all common ski boots, enables a simple, rigid fixation of the toe and heel of the ski boot.In this variant, the first pivot axis can advantageously be moved from the pivot position of the bearing element 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, away from the ski to the downhill position.
[0028] Preferably, the locking element is provided by an opening in the support element, an opening in the bearing element, and a locking bolt that can be inserted into the openings. When the locking bolt is inserted, the bearing element is locked to the support element. In a preferred variant, however, the locking element is a displaceable element in the bearing element, wherein the locking element can be moved into a position in which it is supported on the support element, thereby locking the bearing element to the support element. The ski tourer can lock the ski binding for the descent with a very simple element. Alternatively, this can also be achieved using a frictional or positive-locking element, such as a clamping device or a blocking element.
[0029] The support element preferably has a base plate from which two spaced-apart bearing blocks protrude. The bearing blocks provide the bearing points for pivotally supporting the bearing element relative to the support element. The bearing element extends 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 additional elements, such as an insert element.
[0030] Preferably, the base plate has a mounting surface on the underside with which the support element can be mounted on the surface of a ski.
[0031] Preferably, the base plate has a plurality of mounting holes. The mounting holes serve to accommodate fastening screws with which the support element can be firmly connected to a ski.
[0032] Preferably, the bearing blocks extend from a top side of the base plate and are located on two opposite side edges of the base plate.
[0033] 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 pin. The bearing pin defines the second pivot axis.
[0034] Preferably, the bearing pin is firmly connected to the bearing element. The bearing pin and the bearing openings form a plain bearing, with the bearing pin being pivotable within the plain bearing. Alternatively, the bearing pin is firmly mounted in the opening, and the bearing element is designed to pivot relative to the bearing pin.
[0035] Preferably, the ski boot holder is located outside the space between the two bearing blocks in every position.
[0036] 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 stop surface on the bearing element side and a second stop surface on the bearing element side, wherein in the starting position the first stop surface on the bearing element side bears against the first stop surface on the support element side, and wherein in the pivoting position the second stop surface on the bearing element side bears against the second stop surface on the support element side. In a variant, however, it is also possible for the first stop surface on the bearing element side not to bear against the first stop surface on the support element side in the starting position, while in the pivoting position the second stop surface on the bearing element side bears against the second stop surface on the support element side.In a preferred variant, the first bearing element-side stop surface is located on the first support element-side stop surface in the previously described downhill position, while in the pivoting position the second bearing element-side stop surface is located on the second support element-side stop surface.
[0037] In one variant, the spherical contact surface is provided by a spherical upper side of a base plate. In another variant, the spherical contact surface is provided by a spherical underside of the ski boot. In another variant, the spherical contact surface is provided by a spherical upper side of the base plate and by a spherical underside of the ski boot. The spherical shape can also be provided approximately, for example by a step 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 spherical shape. The contour can further increase the lateral stability of the ski boot.
[0038] The base plate is preferably mounted on the surface of the ski. The base plate's contour and height are preferably coordinated with other elements of the ski binding. The contour and height of the base plate can also be coordinated with the crown of the ski boot. The base plate can also be permanently attached or integrated into the ski. The base plate can also be flat if the ski boot has a crowned underside.
[0039] The base plate is preferably formed separately from the support element. However, the base plate can also be an integral part of the support element.
[0040] Regardless 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 attached to the ski and a cover element that can be attached to the base element, wherein the cover element is movable into a cover position in which a support surface of the cover element is oriented such that the ski boot held in the ski binding can be supported downwards on the support surface, wherein the cover element is movable away from the cover layer, in particular into a cover position, wherein, when the cover element is moved away from its cover position, in particular into the cover position, the crampon can be attached 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 substantially at the same position as the support 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.
[0041] This has the advantage that by moving the cover element away from the top layer, the support surface of the cover element can be moved away, freeing up the space occupied by the cover element in the top layer. This space can then be occupied by a crampon held in the crampon holder. Accordingly, when the cover element is moved away from the top layer, the surface of the crampon can replace the support surface of the cover element and serve to support the ski boot held in the ski binding against the surface of the crampon. This allows for a very compact design of the ski binding.
[0042] This advantage can also be achieved with ski bindings other than those described above as a 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 has a base plate, wherein the base plate has a crampon holding device for attaching and holding a crampon to the base plate, wherein the base plate comprises a base element that can be fastened to the ski and a cover element that can be fastened to the base element, wherein the cover element is movable into a cover position in which a support surface of the cover element is oriented such that the ski boot held in the ski binding can be supported downwards on the support surface, wherein the cover element is movable away from the cover layer, in particular into a cover position, wherein when the cover element is moved away from its cover position, in particular into the cover position,is moved, the crampon is attachable to the crampon holding device in order to be held by the crampon holding device. Advantageously, the crampon is attachable to the crampon holding device in such a way that a surface of the crampon is positioned substantially at the same position as the support 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.
[0043] A ski binding according to this further invention as well as a ski binding according to the invention described at the beginning can have one or more of the following further base plates.
[0044] The crampon holder is advantageously located on the base element. This has the advantage of allowing a particularly simple design for the ski binding. However, a variant also allows the crampon holder to be located on another element of the base plate, such as the cover element.
[0045] In the context of the ski binding with the crowned contact surface mentioned above, the contact surface of the cover element in the top layer of the cover element advantageously forms at least a portion of the crowned contact surface. However, it is not necessary for the contact surface of the cover element in the top layer of the cover element to form at least a portion of the crowned contact surface.
[0046] Preferably, the cover element is movably mounted on the base element, in particular adjustable from the cover layer to the cover layer and back. Particularly preferably, the cover element is mounted on the base element so that it can be adjusted from the cover layer to 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, however, it is also possible for the cover element to be removable from the base element and attachable 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 be pivoted about an axis. Particularly preferably, the cover element is mounted on the base element so that it can be pivoted about the axis from the cover layer to the cover position and back. This has the advantage that the cover element can be adjusted on the base element in a simple and stable manner.
[0047] In a further preferred variant, the cover element is mounted on the base element so that it can be moved, in particular 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 cover layer to the cover layer and back, in particular in the longitudinal direction of the ski. This has the advantage that the cover element requires very little space for adjustment.
[0048] The bearing element preferably has two bearing sections, which 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 are spaced apart from one another such that a gap is created between the bearing sections into which the ski boot can protrude, and the ski boot receptacle is provided at the free end of the bearing sections. Preferably, each free end has a pin that can engage a corresponding bearing point on the ski boot.
[0049] Preferably, the two bearing sections are mechanically coupled to each other. The coupling is such that the two bearing sections run parallel to each other during movement into the pull position.
[0050] The pins protrude from the free end of the bearing section. The two pins are arranged collinearly with each other and define the first pivot axis.
[0051] In a preferred variant, the free end of the bearing sections is designed as a pivoting arm with a joint, which pivots relative to the bearing section. The pivoting arm is preferably designed such that it is locked in a normal position and releases the shoe when opened safely in the event of a fall or other overload.
[0052] In a further preferred variant, the bearing sections are mounted so as to be displaceable relative to one another, essentially horizontally in the transverse direction of the ski, in particular in a body of the bearing element. The two bearing sections can preferably 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 such that the pins can pivot a ski boot in its toe area around the pins and thus around the first pivot axis. Starting from this stop position, the two pins can preferably be moved apart into a release position by moving the bearing sections apart horizontally in the transverse direction of the ski.
[0053] Preferably, the ski binding further comprises a heel locking element, which is arranged behind the support element in the direction of travel of the ski. The heel locking element can be used to lock the rear area of the ski boot to the ski.
[0054] An arrangement comprises a ski boot and a ski binding as described above, wherein the tip of the ski boot has a bearing point for pivotal connection to the ski boot holder.
[0055] Preferably, the bearing point at the tip of the ski boot is a receptacle for receiving said pin, which is arranged on the ski boot receptacle.
[0056] Furthermore, the assembly can comprise a ski, with the ski binding being attached to the ski by means of the support element. The term "ski" can be understood to mean an alpine ski, a touring ski, a cross-country ski, a telemark ski, or a detachable ski part of a snowboard.
[0057] Further embodiments are specified in the dependent claims.

[0060] In principle, identical parts in the figures are provided with identical reference symbols. Ways to implement the invention
[0061] In the Figures 1a to 5bA 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, a cross-country ski binding, or a binding for a divisible snowboard.
[0062] The ski binding 1 comprises a support element 2 that can be attached to the ski, a bearing element 3 with a ski boot holder 4, which is designed such that the ski boot 5 is pivotally mounted in the ski boot holder 4 about a first pivot axis S1, and a spherical support surface 6 on which the ski boot 5 can roll. The bearing element 3 is pivotally connected to the support element 2 via a second pivot axis S2.
[0063] The support element 2 has a base plate 10. Two spaced-apart bearing blocks 11 protrude from the top of the base plate 10. 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.
[0064] The base plate 10 comprises several 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. The bearing element 3 can be pivoted relative to the support element 2. The bearing element 3 lies partially between the two bearing blocks 11. Each of the bearing blocks 11 has a bearing opening 12. 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. The bearing pin 13 defines the second pivot axis S2. In one variant, the bearing pin 13 is pivotally 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 fixedly mounted in the bearing openings 12 and the bearing element 3 has an opening through which the bearing pin extends such that the bearing element 3 can be pivoted relative to the bearing pin 13.
[0065] 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 to a pivoted position. The ski boot holder 4 is located outside the space between the two bearing blocks 11.
[0066] The bearing element 3, as already explained, is formed with a ski boot holder 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 from one another such that a gap is created between the bearing sections 24. The ski boot 5 can protrude into this gap. Furthermore, the ski boot holder 4 is located at the free end of the bearing sections 24. In the embodiment shown, the ski boot holder 4 has a pin 25 on each of the bearing sections 24, which pin protrudes into the gap between the two bearing sections 24.The two pins 25 extend along the same axis and engage bearing points 23 on the ski boot 5. The pins 25 and the engagement with the bearing points 23 define the first pivot axis S1. The bearing section 24 further has a joint 26, the free end of which is pivotable about the joint 26, so that the pin 25 can engage the bearing points on the ski boot 5 via the joint 26. Preferably, the joint 26 and / or the bearing section 24 are blocked from movement from the standing position to the pulling position, so that the ski binding cannot open.
[0067] The spherical support surface 6, on which the ski boot 5 can roll, is provided in the embodiment shown by a base plate 20 with a spherical upper surface 19 and a spherical underside 21 of the ski boot 5. The ski boot 5 can roll on the spherical support surface 6.
[0068] The first pivot axis S1 runs parallel to the second pivot axis S2, and the first pivot axis S1 can be pivoted about the second pivot axis S2 by a pivot angle α. The maximum pivot angle α of the first pivot axis S1 about the second pivot axis S2 is preferably in the range of 10° to 35°, in particular in the range of 20° to 30°.
[0069] 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 position, the first bearing-element-side stop surface 17 rests against the first support-element-side stop surface 15, and in the pivoted position, the second bearing-element-side stop surface 18 rests against the second support-element-side stop surface 16.
[0070] Furthermore, the ski binding 1 preferably has a locking element 7, with which the bearing element 3 can be locked to the support element 2, thus preventing pivoting between the bearing element 3 and the support element 2. The locking mechanism is activated when the ski is used for a descent.
[0071] 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 bolt that can be inserted into the opening 8, 9. In the inserted state, the bearing element 3 is locked to the support element 2.
[0072] Based on the Figures 1a to 5b The movement sequence of ski binding 1 will now be explained in more detail.
[0073] In the Figures 1a / 1bThe ski binding 1 is shown in a standing position. The skier, especially 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 the ski boot 5 moves into a pulling position, as in the Figures 5a / 5b shown.
[0074] Starting from the standing position, the ski boot 5 rolls on the spherical support surface 6.
[0075] At the beginning of the rolling process, the ski boot 5 rolls on the spherical surface 6. At the same time, a pivoting movement of the ski boot 5 about the first pivot axis S1 is executed or brought about by the connection between the ski boot 5 and the ski boot holder 4. Also at the same time, a pivoting movement of the bearing element 3 about the second pivot axis S2 is initiated or carried out, whereby the bearing element 3 is pivoted from its initial position relative to the support element 2 toward its pivot position. In other words, the tip 22 of the ski boot 5 presses the ski boot holder 4 downward, resulting in the aforementioned pivoting movements.
[0076] In the standing position, the first pivot axis S1 and the second pivot axis S2 span a reference plane E. During the movement into the pulling position, the first pivot axis S1 is moved away from this reference plane E and 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.
[0077] In the Figures 2a / 2bIt can be clearly seen how the ski boot 5 rolls on the spherical support surface 6. The contact point between the ski boot 5 and the spherical support surface moves from the standing position towards the support element 2 with increasing degree of rolling. At the same time, the ski boot 5 is pivoted further about the first pivot axis S1 relative to the bearing element 3. 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.
[0078] When the ski boot 5 moves into the pulling position, the ski boot 5 pivots about the first pivot axis S1, and the bearing element 3 and the first pivot axis S1 pivot about the second pivot axis S2. In doing so, the boot holder 4 pivots downward toward the support element 2 with the first pivot axis S1 relative to the second pivot axis S2. This means that the first pivot axis S1 pivots toward the top of a ski.
[0079] In the Figures 3a / 3ba position between the standing position and the pulling position is shown. In the position shown, which can also be referred to as the intermediate position, the rolling process between the spherical support surface 6 and the ski boot 5 is completed. Likewise, the pivoting movement about the second pivot axis S2 is completed. The second bearing element-side stop surface 18 rests against the second support element-side stop surface 16, whereby the bearing element 3 rests firmly against the support element 2. In the position shown, the maximum pivot angle of the bearing element 3 relative to the support element 2 is reached. The pivot angle is in the Figure 3b with the reference symbol α.
[0080] Based on the Figures 3a / 3bshown position, the ski boot 5 is now moved further in the direction of the pulled position. In doing so, 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 pivot direction as from the starting position into the intermediate position relative to the pivot mount 4. At the same time, the bearing element 3 moves. In a first phase of the further movement into the pulled position, the bearing element 3 continues to be firmly in contact with the support element 2 in the pivot position. In a second phase of the movement into the pulled position, the bearing element 3 is pivoted back into its starting position with respect to the support element, the bearing element 3 bearing with its first stop surface 17 on the bearing element side against the first stop surface 15 on the support element side.
[0081] In the Figures 5a / 5bThe pulling position is shown. In the pulling position, the actual rolling process of the ski boot 5 is completed, and the skier pulls the ski accordingly. The bearing element 3 and the ski boot 5 are then moved back to the standing position.
[0082] With this sequence of movements, especially due to the movement limitations at the stops, even typical necessary movements such as hairpin turns or short descents can be carried out without locking the heel, in a stable manner and without the skier feeling unsafe.
[0083] In the Figures 6 to 10b Another ski binding 101 according to the invention is shown, which is a touring ski binding. Figures 6 to 10bOnly the front unit of the ski binding 101 is shown. 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 heel locking element can be used to lock the rear area of the ski boot to the ski. Such heel locking elements are known. An example of such a heel locking element is described in EP 3 195 906 A1 by Fritschi AG - Swiss Bindings. In EP 3 195 906 A1, the heel locking element is referred to as an automatic heel mechanism.
[0084] In the Figure 6 is an exploded view in an oblique view of the ski binding 101. Based on this illustration, the elements of the ski binding 101 are explained, which elements of the Figures 1a to 5b shown ski binding 1. At the same time, deviations from the Figures 6 to 10b shown ski binding 101 to the Figures 1a to 5bThe following section will be explained in connection with the Figures 7a to 10b the functionality of the ski binding 101 is explained in more detail.
[0085] The Figures 6 to 10b The ski binding 101 shown comprises a support element 102 that can be attached to the ski and a bearing element 103 with a ski boot holder 104, which is designed such that a ski boot (not shown here) can be pivotally mounted in the ski boot holder 104 about a first pivot axis S101 with respect to the ski boot holder 104. Furthermore, the ski binding 101 comprises a spherical support surface 106 on which the ski boot can roll. The bearing element 103 is pivotally connected to the support element 102 via a second pivot axis S102.
[0086] 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 to form two bearing blocks 111. The bearing blocks 111 thus protrude from the top 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 the passage of fastening screws, via which the support element 102 can be attached to the ski.The fastening screws are first passed 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.
[0087] The bearing blocks 111 provide the bearing points for the pivotable mounting of the bearing element 103. This allows the bearing element 103 to pivot relative to the support element 102. The bearing element 103 lies partially between the two bearing blocks 111. Each of the bearing blocks 111 has a bearing opening 112. 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. The bearing pin 113 defines the second pivot axis S102. In one variant, the bearing pin 113 is pivotally 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 fixedly mounted in the bearing openings 112 and the bearing element 103 has an opening through which the bearing pin extends such that the bearing element 103 can be pivoted relative to the bearing pin 113.
[0088] The bearing element 103 is connected to the support element 102 so that it can pivot about the second pivot axis S102 from a downhill position to a pivot position. During a continuous pivoting movement from the downhill position to the pivot position, the bearing element 103 can first be moved into a starting position and then from the starting position into the pivot position. This means that the starting position is located between the downhill position and the pivot position. The ski boot holder 104 is located outside the space between the two bearing blocks 111.
[0089] The bearing element 103, as already explained, is formed with a ski boot holder 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 such that a gap is created between the bearing sections 124. The ski boot can protrude into this gap. Furthermore, the ski boot holder 104 is located at the free end of the bearing sections 124. In the embodiment shown, the ski boot holder 104 has a pin 125 on each of the bearing sections 124, which protrudes into the gap between the two bearing sections 124.The two pins 125 run along 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 bearing points define the first pivot axis S101, which is in the . Figure 6shown as a dotted line. The bearing sections 124 are mounted horizontally in the transverse direction of the ski in a body of the bearing element 103. This allows the pins 125 to be moved apart into an entry position. In this entry position, the two pins 125 are moved sufficiently far apart so that the tip of the ski boot can be guided between the pins 125. Furthermore, the pins 125 can be moved towards each other from the entry position into a holding position. If the tip of the ski boot is between the pins 125, the pins 125 can engage in the bearing points on the ski boot and hold the ski boot pivotably about the first pivot axis S101.This movement of the bearing sections 124 with the pins 125 apart into the entry position and towards each other into the holding position is achieved by means of a slider 150, similar to that described in EP 3 566 754 A1 of Fritschi AG - Swiss Bindings. For this purpose, the ski binding 101 comprises the slider 150 and an elastic element 151 in the form of a spiral spring. Both the slider 150 and the elastic element 151 are arranged in the body of the bearing element 103, essentially aligned in the longitudinal direction of the ski, and are accordingly pivotable 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. Towards the rear, the elastic element 151 is supported against the body of the bearing element 103 and towards the front against the slider 150.In the assembled state of the ski binding 101, the elastic element 151 is preloaded and pushes the slider 150 forward relative to the body of the bearing element 103. In the presently shown embodiment, the preload of the elastic element 151 is predetermined by the shape of the body of the bearing element 103 and the slider 151. In variants, however, the preload of the elastic element 151 is adjustable. This can be achieved, for example, by means of a screw or a combination of a screw and a nut, as is known in the technical field of ski bindings.
[0090] The slider 150 extends rearward below the elastic element 151 to below the two bearing sections 124. The slider 150 has a third guide shape below the first bearing section 124 and a fourth guide shape below the second bearing section 124. Both the third guide shape and the fourth guide shape are formed by grooves running diagonally from the center of the ski to the front. Furthermore, the first bearing section 124 has a first guide shape on its underside, while the second bearing section 124 has a second guide shape on its underside. The first guide shape is complementary to the third guide shape, while the second guide shape is complementary to the fourth guide shape. In the assembled state of the ski binding 101, the first guide shape interacts with the third guide shape, while the second guide shape interacts with the fourth guide shape.The slider 150 is thus operatively connected to the first bearing section 124 through the interaction of the first guide shape with the third guide shape, and to the second bearing section 124 through the interaction of the second guide shape with the fourth guide shape. When the slider 150 is thus displaced, the first guide shape is displaced relative to the third guide shape and the second guide shape is displaced relative to the fourth guide shape. Therefore, by displacing the slider 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 displaced relative to one another, whereby the first pin 125 and the second pin 125 are also moved towards one another, towards their holding position. Since the slider 150 is prestressed forward by the prestressed elastic element 151, the two pins 125 are thus prestressed towards one another towards their holding position.
[0091] However, the slider 150 is also operatively connected to the first bearing section 124 and the second bearing section 124 such that, by moving 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, whereby the first and second pins 125 are moved away from one another away from their holding position.
[0092] As explained below in connection with the Figures 9a to 9dAs described above, 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.
[0093] The spherical support surface 106, on which the ski boot can roll, is formed in the Figures 6 to 10bThe 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 160 is attached to the base plate 120 or not, the base plate 120 is fastened to the ski by means of screws behind the support element 102. 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 assembled 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 the passage of 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 tight into the ski.The cover element 133 is pivotally mounted on the base element 132 at its rear end about an axis. When the cover element 133 is tilted forward, the cover element 133 is in a covering position. In this covering position, a support surface 161 of the cover element 133 is oriented such that the ski boot held in the ski binding can be supported downwardly on the support surface 161. When the cover element 133 is in this covering position, the base element 132 and the support surface 161 of the cover element 133 together form a spherical upper surface 119, which forms the spherical support surface 106. The ski boot can roll on this spherical support surface 106. However, the cover element 133 can also be pivoted rearward 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. On this crampon holding device 162, as shown in the . Figures 9a to 10billustrated, a crampon 160 can be attached when the cover element 133 is pivoted rearward into its covering position relative to the base element 132. When the crampon 160 is thus attached to the crampon holder device 162, the base element 163 and a surface of the crampon 160 together form the spherical support surface 106 when the crampon 160 is as shown in the Figures 9a to 9dshown 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 essentially at the same position as the support surface 161 of the cover element 133 in the cover layer, in order to support the ski boot held in the ski binding 101 downwards on the surface. In a variant of the pivotable cover element 133, the cover element can also be displaceably mounted on the base element. For example, the cover element can be displaceably mounted on the base element in the longitudinal direction of the ski from its cover layer to its cover layer. In a further variant, however, it is also possible for the cover element to be attachable to the base element in the cover layer and removable from the base element in order to free up the space for attaching the crampon 160 to the crampon holding device 162.
[0094] 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 pivot angle α of the first pivot axis S101 about the second pivot axis S102 is 32.12° in the present exemplary embodiment. During 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 pivot position. In the downhill position, the pins 125 are 19 mm higher above the ski than in the pivot position. This means that during a pivoting movement of the bearing element 103 about the second pivot axis S102, the height of the pins 125 above the ski is adjusted by a maximum of 19 mm.
[0095] When the ski boot is held in the ski binding 101 in the ascent configuration and is in the standing position, i.e. with the heel of the ski boot lowered as far as possible towards the ski and the ball of the ski boot supported on the base plate 120, the bearing element 103 is 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 have different shapes in their front area, the pins 125 can also be at a slightly different height above the ski in the starting position of the bearing element 103 when the respective ski boot is in the standing position.For example, depending on the ski boot, the pins 125 in the initial position of the bearing element 103 can be 14 mm higher above the ski than in the pivoted position. Depending on the ski boot, the pins 125 in the initial position of the bearing element 103 can also be 17 mm higher above the ski than in the pivoted position.
[0096] The support element 102 has a first support-element-side stop surface 115 and a second support-element-side stop surface 116. The bearing element 103 has a first bearing-element-side stop surface 117 and a second bearing-element-side stop surface 118. In the down position, the first bearing-element-side stop surface 117 abuts the first support-element-side stop surface 115, and in the pivot position, the second bearing-element-side stop surface 118 abuts the second support-element-side stop surface 116. This limits the pivoting movement of the bearing element 103 about the second pivot axis S102.
[0097] 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, thus preventing pivoting between the bearing element 103 and the support element 102. This locking mechanism can be activated when the ski is used for a downhill run.
[0098] In the Figures 6 to 10bIn the embodiment shown, the locking elements 107 are guided in slots 109 in the body of the bearing element 103. By pushing the locking elements 107 backward in the slots 109, they project beyond the body of the bearing element 103 and are supported downwards on the second support-element-side stop surface 116. In this position, the first bearing-element-side stop surface 117 simultaneously bears against the first support-element-side stop surface 115. Since the first bearing-element-side stop surface 117 and the first support-element-side stop surface 115 are located in front of the second pivot axis S102, while the second support-element-side stop surface 116 is located behind the second pivot axis S102, the bearing element 103 is thereby locked in the downhill position. To release this locking, the locking elements 107 can be pushed forward in the slots 109.This releases the pivoting movement of the bearing element 103 relative to the support element 102, so that the bearing element 103 can be pivoted from the downhill position into the pivoting position, where the second bearing element-side stop surface 118 rests against the second support element-side stop surface 116.
[0099] The Figures 6 to 10bThe ski binding 101 described comprises an actuating lever 140, which is pivotally mounted on the body of the bearing element 103 about an actuating lever axis 141 oriented horizontally in the transverse direction of the ski. This actuating lever axis 141 extends 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 pivotally mounted on the actuating lever 140 about a release lever axis 144 oriented horizontally in the transverse direction of the ski. Below the actuating lever axis opening 142, a pivot element 146 is pivotally mounted on each side of the actuating lever 140 about an axis oriented horizontally in the transverse direction of the ski.These two pivot elements 146 have downward-facing knobs below their axle bearings, with which they each engage in a recess 158 in a front area of one of the two locking elements 107. Depending on the position of the actuating lever 140, the locking elements 107 can thus be displaced by a movement of the actuating lever 140 in the body of the bearing element 103.
[0100] The ski binding 101 further comprises a connecting slider 152, which is displaceable below the slider 150 in the body of the bearing element 103, essentially in the longitudinal direction of the ski. A tread 153 is pivotally mounted at a rear end of the connecting slider 152 about an axis oriented horizontally in the transverse direction of the ski. This tread 153 serves 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.
[0101] The connecting slide 152 has two upwardly facing cams 154 at its front end, which, in the assembled state, extend from the bottom upward into downwardly open recesses on an underside of the actuating lever 140. However, these downwardly open recesses on the underside of the actuating lever 140 are not visible in the figures.
[0102] When the actuating lever 140 is pulled upward with its free actuating end pointing forward, the downwardly open recesses on the underside of the actuating lever 140 are moved forward. As soon as the upward-facing cams 154 of the connecting slide 152 rest against 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 153. If, on the other hand, the actuating lever 140 is moved downward towards the ski with its free actuating end pointing forward, the downwardly open recesses on the underside of the actuating lever 140 are moved backward. As a result, due to the upward-facing cams 154 of the connecting slide 152, the connecting slide 152 and thus also the tread 153 are moved backward.
[0103] In Figure 7aAn oblique view of the ski binding 101 in the step-in configuration is shown. The illustration shows that the forward-facing free actuating end of the actuating lever 140 is lowered toward the ski, while the pins 125 are in their step-in position. The tread 153 is located below the pins 125 and points diagonally upwards toward the rear.
[0104] In Figure 7b A vertical cross-section through the ski binding 101 in the step-in configuration is shown, running in the longitudinal direction of the ski. This shows the elastic element 151 pre-tensioned between the slider 150 and the body of the bearing element 103. It can also be seen how the connecting slider 152 is arranged below the slider 151 in the body of the bearing element 103, so that it can be moved in the longitudinal direction of the ski. It can be seen that the connecting slider 152 is located in a rearward position in the body of the bearing element 103.
[0105] In the Figures 7a and 7b In the entry configuration shown, the locking elements 107 are pushed rearward in the slots 109, project rearward beyond the body of the bearing element 103, and are supported downwards on the second support-element-side stop surface 116. As already described, in this position of the locking elements 107, the first bearing-element-side stop surface 117 simultaneously rests against the first support-element-side stop surface 115. As a result, the bearing element 103 is locked in the downhill position because the first bearing-element-side stop surface 117 and the first support-element-side stop surface 115 are located in front of the second pivot axis S102, while the second support-element-side stop surface 116 is located behind the second pivot axis S102.
[0106] Without external force, the ski binding 101 remains in the entry configuration, although the elastic element 151 is clamped between the body of the bearing element 103 and the slider 150. This is achieved by the fact that the actuating lever 140 has a stop 156 on its rear side below the actuating lever axis 143. This stop 156 is in the Figure 6 and acts with a slide 150 arranged, also in Figure 6visible first counter-stop 157. In the entry configuration, the stop 156 arranged on the actuating lever 140 and the first counter-stop 157 arranged on the slider 150 are aligned with one another such that the slider 150, pushed forward by the elastic element 151, exerts a force on the actuating lever 140 that is directed obliquely forward and upward toward the actuating lever axis 141. Since the actuating lever axis 141 is mounted in the body of the bearing element 103, against which the elastic element 151 also repels, this ensures that in the entry configuration, the elastic element 151 does not exert any torque on the actuating lever 140, and the ski binding remains in the entry configuration without the application of external force.
[0107] As in the Figures 7a and 7bAs can be seen, the release lever 143 is essentially vertically upward in the entry configuration. As already mentioned, the release lever 143 is mounted on the actuating lever 140 so that it can pivot about the release lever axis 144. A leg spring is wound around the release lever axis and pretensions the release lever 143 relative to the body of the bearing element 103 so that its upward-pointing free end is pretensioned rearward. In the entry configuration, however, the release lever 143 is held in its essentially vertical orientation because its lower end is supported on the body of the bearing element 103. This prevents the release lever 143 from being pivoted rearward by the leg spring. In a variant, however, it is also possible for the release lever 143 not to be pretensioned by a leg spring.In this case, the orientation of the trigger lever 143 can also be controlled by a portion of the trigger lever abutting the body of the bearing element 103.
[0108] When a ski boot is inserted with its tip between the pins 125 and is moved downwards so that the tread spur 153 is pressed downwards by the sole of the ski boot, a Figure 6visible 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 slide 152 forward. This leads to the actuating lever 140 being moved slightly upwards with its free actuating end by the upward-facing cams 154 of the connecting slide 152, as described above. This rotation of the actuating lever 140 with its free actuating end slightly upwards 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. This leads to the force acting on the actuating lever 140, which is caused by the slide 150 being pushed forward by the elastic element 151, also changing its alignment and pointing more flatly forwards.As soon as the orientation of this force is sufficiently lowered and points forwards below the actuating lever axis 141, a sufficiently large torque is exerted on the actuating lever 140 so that the actuating lever 140 is pivoted upwards with its free actuating end until the free actuating end points forwards substantially horizontally.
[0109] During this rotational movement of the operating lever 140, the two pivotally mounted on the operating lever 140, in Figure 6recognizable pivoting elements 146 are also moved. However, the two pivoting elements 146 are pivoted relative to the actuating lever 140, so that their downward-facing knobs rotate in the recesses 158 in the front area of one of the two locking elements 107. Therefore, the locking elements 107 are not displaced relative to the body of the bearing element 103 and thus remain in their locking position, in which they project rearward beyond the body of the bearing element 103 and are supported downwards on the second stop surface 116 on the support element side. As a result, the pivoting movement of the bearing element 103 relative to the support element 102 is still prevented, and the bearing element 103 remains locked in its down position.
[0110] However, with the previously described rotational movement of the actuating lever 140, until the free actuating end of the actuating lever 140 points substantially horizontally forward, the slider 150 in the body of the bearing element 103 is also pushed forward, so that the two bearing sections 124 are moved toward each other and the two pins 125 are moved into their holding position, in which they engage 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.
[0111] In Figure 8aAn oblique view of the ski binding 101 in the downhill configuration is shown. 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 their rearward position. Accordingly, the bearing element 103 cannot be pivoted about the second pivot axis S102 relative to the support element 103.
[0112] In the presentation of the Figure 8a It can be seen that in the downhill configuration, the forward-facing free actuating end of the actuating lever 140 points essentially horizontally forward, while the pins 125 are in their holding position. The tread spur 153 is still located below the pins 125. However, its rearward-facing, free end is lowered compared to the entry configuration and points essentially horizontally backward. This is particularly true in Figure 8bwhich shows a vertical cross-section through the ski binding 101 in the entry configuration.
[0113] As in Figure 8b compared to Figure 7b As can be seen, the slider 150 and the connecting slider 152 are moved further forward in the body of the bearing element 103 in the downhill configuration than in the uphill configuration. Due to the changed position of the slider 150, the elastic element 151 is less preloaded in the downhill configuration than in the uphill configuration.
[0114] Further in Figure 8b It can be seen that the release lever 143, in contrast to the Figure 7bshown entry configuration, in the downhill configuration, the release lever axis 144 is essentially oriented horizontally to the rear. The reason for this is that, due to the pivoting movement of the actuating lever 140 relative to the body of the bearing element 103, the release lever axis 144 is also positioned differently relative to the body of the bearing element 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 configuration. Therefore, the release lever 143 has now been pivoted by the leg spring and points rearward with its free end. Accordingly, the release lever axis 144 is located in the front region of the release lever 143 in the downhill configuration, while a central region of the release lever 143 is supported downwards on the body of the bearing element 103 in the region of the second pivot axis S102. In addition, the free end of the release lever forms a free-standing rear region of the release lever 143.Thus, if a ski boot held in the ski binding 101 is released from the heel locking element in the event of a forward fall by the skier and is pivoted forward and upward about the pins 125 and thus about the first pivot axis S101, the toe area of the ski boot presses, from a certain pivot angle, obliquely from the rear and top onto the rear area of the release lever 143. This pushes the rear area of the release lever 143 forward and downward. This results in the actuating lever 140 being pushed downward via the release lever axis 144 with its free actuating end pointing forward. Due to the pivoting movement of the actuating lever 140 thus enforced, the slider 150 is pushed rearward due to the interaction of the stop 156 with the first counter-stop 157.This rearward movement of the slider 150 causes the bearing sections 124 to move apart and the pins 125 to move away from their holding position. Once the pins 125 are moved sufficiently far apart, the ski boot is released from the ski binding 101.
[0115] Starting from the downhill configuration, the 101 ski binding can be adjusted to an ascent 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 ascent configuration by pulling the free actuating end of the actuating lever 140 upwards until the free actuating end points substantially vertically upwards. During this rotational movement of the actuating lever 140, the two pivotally mounted on the actuating lever 140, Figure 6visible pivoting elements 146 are moved forward. During this movement, the two pivoting elements 146 are no longer just pivoted relative to the actuating lever 140. Rather, the locking elements 107 are now pulled forward by the downward-facing knobs of the pivoting elements 146, which engage in the recesses 158 in the front region of the two locking elements 107. Therefore, the locking elements 107 are moved forward relative to the body of the bearing element 103 into a release position in which they no longer project rearward beyond 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 into the pivoting position and back.
[0116] In the Figure 9aTherefore, an oblique view of the ski binding 101 is shown in the ascent configuration, with the bearing element 103 in the downhill position. Figure 9b In contrast, an oblique view of the ski binding in the ascent configuration is shown, with the bearing element 103 in the pivot position. Analogously, Figure 9c a vertical cross-section through the ski binding 101 in the ascent configuration with the bearing element 103 in the downhill position, while in the Figure 9d a vertical cross-section in the longitudinal direction of the ski through the ski binding 101 in the ascent configuration with the bearing element 103 in the pivoting position is shown.
[0117] By pulling the free actuating end of the actuating lever 140 upwards when adjusting from the downhill configuration to an ascent configuration until the free actuating end points substantially vertically upwards, the connecting slide 152 is also pulled further forward by the actuating lever 140 on the cams 154. As shown 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 pulled further forward than in the descent configuration.
[0118] Together with the connecting slide 152, the tread 153 pivotally mounted on the connecting slide 152 is also pulled further forward. As a result, the tread 153 is almost completely retracted into the body of the bearing element 103, freeing up the space below the pins 125 for the toe area of the ski boot. Accordingly, the ski boot held in the ski binding 101 can be pivoted around the pins 125 and thus around the first pivot axis S101 without being hindered by the tread 153.
[0119] By pulling the free actuating end of the actuating lever 140 upwards when adjusting from the downhill configuration to an ascent configuration, the stop 156 on the actuating lever 140 is also pivoted forwards. This stop 156 arranged on the actuating lever 140 is described above in connection with the Figures 7a and 7balready 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 located below the actuating lever axis 141 in the ski longitudinal direction in front of the actuating lever axis 141. As a result, the stop 156 arranged on the actuating lever 140 abuts a second counter-stop 159 arranged in the front area of the slider 150 and directed backwards. This second counter-stop 159 is in the Figure 6 can be seen in the exploded view shown.
[0120] In the ascent configuration, the stop 156 and the second counter-stop 159 are aligned with each other and interact with each other in such a way that a force acting rearward on the slider 150 causes a force directed in the direction of the actuating lever axis 141 on the actuating lever 140. Therefore, no torque is exerted on the actuating lever 140 when the slider 150 is pushed or pulled rearward. This ensures that the actuating lever 140 remains in its substantially vertical orientation despite the force acting on the slider 150, and the slider 150 can no longer be moved rearward in the body of the bearing element 103, but is locked in position. Due to this blocking of the slider 150 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, in the ascent configuration, a ski boot held in the ski binding 101 cannot inadvertently detach from the ski binding 101. 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 while walking without detaching from the ski binding 101.
[0121] 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 holder 162 for attaching a crampon 160 in its front area, the crampon 160 can be attached to the base element 132 when the cover element 133 is pivoted backwards relative to the base element 132 into the covering position. For this purpose, the crampon 160 can be in a vertical orientation as shown in the Figures 10a and 10b shown from the side in the transverse direction of the ski into the crampon holder 162 in the base plate 131. The crampon 160 can then be inserted as shown in the Figures 9a to 9dshown with its main surface facing rearward toward the ski onto the base element 132 and the cover element 133. Since, when the crampon 160 is attached to the base plate 120, the cover element 133 is pivoted rearward into the covering position, the base element 132 and the cover element 133 have a lower height than when the cover element 133 is pivoted forward into the covering position on the base element 132. This lower height in the covering position can be filled with the crampon 160, so that the contact surface 161 of the crampon 160 together with the front region of the base element 132 form the spherical contact surface 106.
[0122] In summary, it can be stated that a ski binding, in particular a touring ski binding, is specified that enables an improved movement sequence during ascent.
