Description

The invention relates to a ski binding with a toe holder, which preferably defines a pivot axis for a ski boot held by the toe holder in a plan view of the ski binding transversely to a longitudinal direction of the ski binding, and a heel holder with a heel holder housing and a first holding element and a second holding element for a holding engagement with a ski boot heel. The first holding element and the second holding element can be pivoted out of the holding engagement about a respective pivot axis, the position of which can be adjusted relative to the corresponding holding element. The position of the pivot axes relative to the holding elements determines a release force required to release the holding engagement.

It is an object of the invention to easily and precisely adjust a force for vertical release of a heel holder, for example in the event of a fall.

This task according to the invention is fulfilled by a ski binding with the features of claim 1.

The invention relates to a ski binding with a toe holder, which in a plan view of the ski binding defines a pivot axis for a ski boot held by the toe holder transversely to a longitudinal direction of the ski binding, and a heel holder.

The ski binding is preferably a ski binding that can be used by the user for touring and alpine driving. The heel holder can be connected to the ski body or to a plate that can be moved relative to the ski body.

The toe holder can be a toe holder known in the art.

The heel holder comprises a base, a heel holder housing projecting from the base, a first holding element and a second holding element, a bearing section, each an engagement section for a holding engagement with a Ski boot heel, wherein the holding elements have a coupling section in the longitudinal direction between the engagement section and the bearing section.

Furthermore, the heel holder comprises a support device which receives the holding elements in the area of the respective bearing section, an adjusting structure which, in a side view transverse to the longitudinal direction, in engagement with the coupling section of the first holding element, has a pivot axis for the first holding element and in engagement with the coupling section of the second holding element defines a pivot axis for the second holding element.

The holding elements can be pivoted about the respective pivot axis against a preload force. The adjusting structure can be adjusted into different adjusting positions relative to the heel holder housing and the holding elements and can be fixed in each of the adjusting positions. The adjustment of the adjusting structure changes the position of the respective pivot axis relative to the holding elements and preferably also relative to the heel holder housing and thereby adjusts a release force of the heel holder required to release the holding engagement.

The first holding element and the second holding element are parts of a single holding element body. The holding element body can in particular be clip-shaped or bow-shaped, whereby the clip or bow can be, for example, U-, V-, W- or H-shaped.

In one embodiment, the holding element body is a bracket, preferably a U-bracket. The legs of the bracket form the holding elements. The free ends of the bracket or areas at the free ends of the beams including the free ends form the engagement sections of the first holding element and the second holding element. A connecting section of the bracket connecting the holding elements, or legs, forms the bearing section. The connecting section can be curved or straight except for transition areas in which the first holding element and the second holding element are connected to the connecting section. In a top view, the connecting section can also be wave-shaped or triangular or have any other shape with which the bracket can be can be represented. If the connecting section is arcuate, the arc can be curved concavely or convexly relative to the open end of the bracket.

The legs of the bracket form the coupling sections in an area between the free ends or the engagement sections and the bearing section. The legs can run essentially parallel to one another. The length of the legs between the respective free end and a transition into the bearing section are preferably identical. The legs are particularly preferably designed to be identical or mirrored in shape and length.

The first holding element can form a first holding element arm and the second holding element can form a second holding element arm of the holding element body. The first and second holding element arms can run at least substantially parallel to one another in a load-free state of the holding element body, and the bearing section connects the first holding element arm and the second holding element arm to one another. The connection can in particular be immediate and inseparable.

The holding element body can in particular form a pretensioning device, against the pretensioning force of which the holding elements can be pivoted about the respective pivot axis out of the holding engagement. The pretensioning device in U-shape or another bracket shape forms a pretensioning device due to its shape or bending elasticity, which, when the U-beams are deflected by force, returns them elastically back to the opening position, as long as the force does not cause a buckling or a permanent deformation of the U-shape.

In one embodiment, the holding element body is originally formed in one piece from a profile material. Suitable materials are metals with good bending elasticity, such as steel, copper or nickel, or non-metals with comparable properties, for example PET with or without fiber reinforcement made of glass or carbon. A bracket made of spring steel, for example, is particularly advantageous. The holding element body can be easily and inexpensively brought into the bracket shape from a wire or bar material by forming, such as by bending or edging.

The holding element body can in particular be a profile with a circular, part-circular, oval or polygonal cross section. An outer surface of the profile can be smooth or machined, for example comprising longitudinal and/or transverse grooves. The profile material can be a solid profile or, in principle, a hollow profile. The profile can be processed into the holding element body using tools or can be treated after shaping, for example refined. The holding element can be made from the profile material by bending, pressing and/or cutting.

In principle, the holding element body can also consist of several parts that are joined together to form the holding element body. The profile can consist of several layers, with different physical properties, which are glued or welded together. The layers can lie axially next to one another or an outer layer of material can radially envelop an inner layer of material immediately underneath.

In one embodiment, the holding element body is held with the bearing section in the heel holder housing in such a way that the holding element body cannot move at least in the longitudinal direction relative to the heel holder housing. Movement of the holding element body transversely to the longitudinal direction can also be at least substantially prevented by storage in the heel holder.

The bearing housing can be made up of several parts. The heel holder housing can thus comprise at least a first bearing housing part, in which a receptacle is formed for at least the bearing section of the holding element body. The receptacle can be formed by a recess such as a groove, the shape of which essentially corresponds to the shape of the bearing section of the holding element body in a plan view of the heel holder. The receptacle can have a width in the longitudinal direction which essentially corresponds to a maximum diameter of the bearing section lying in the receptacle in the longitudinal direction. The receptacle can have a depth transverse to the longitudinal direction that is greater than a maximum diameter of the bearing section lying in the receptacle transverse to the longitudinal direction, for example 1.5 or 2 times as deep as the diameter. A second heel holder housing part can have a cover for the form at least one first heel holder housing part, which can be captively connected to the first heel holder housing part. On an inside facing the first heel holder housing part, the cover can comprise an engagement structure which projects into the receptacle when the heel housing is closed and/or rests on the bearing section or a part of the bearing section of the holding element body, so that the holding element body lying in the receptacle does not tilt in the receptacle , that is, cannot move transversely to the longitudinal direction in the Z direction. However, a pivoting movement of the bearing section about a point or section of its radial central axis with a pivot axis that runs essentially transversely to the longitudinal axis in the Y direction may be possible.

The adjusting structure causes in particular an adjustment of the position of the respective pivot axis relative to the holding element body in the longitudinal direction. The adjusting structure can be bracket-shaped or bow-shaped, with a main strut or traverse and two arms projecting essentially vertically at the ends of the main strut and extending essentially parallel to one another. The arms each include a free end. The arms are firmly connected to the main strut or are originally formed in one piece with the main strut. The first arm, which cooperates with the coupling section of the first holding element, and the second arm, which cooperates with the coupling section of the second holding element, can be bent in the area of their free ends so that the free ends lie opposite one another. The first arm and the second arm can rest on the first or second holding element on the inner side facing each other or on the outer side facing away from each other and/or grip around the respective holding element laterally on the inside or outside. The arms can be elastically deformed by force, for example from the holding elements. The main strut can be arranged above or below the holding elements in a plan view of the heel holder.

The adjusting structure can be adjusted into different adjusting positions relative to the heel holder housing and the holding elements and can be fixed in each of the adjusting positions. The adjustment of the adjusting structure adjusts the position of the respective pivot axis relative to the holding elements and preferably also relative to the Heel holder housing and thereby changes, for example, a release force required to release the holding engagement in the vertical direction.

The adjusting structure is preferably movable linearly in the longitudinal direction of the ski binding. For this purpose, the adjusting structure can be continuously moved along the coupling sections and secured in every position against unwanted displacement. The adjusting structure can be moved into different, predetermined locking positions. The locking positions can be formed directly on the holding elements, for example by troughs.

In one embodiment, the adjusting structure comprises a first adjusting element for the first holding element and a second adjusting element for the second holding element. The first actuating element and the second actuating element can each comprise an actuating element housing and an abutment element for the respective holding element in the area of the coupling section. The actuator housing is arranged in a stationary manner in the heel holder housing, can for example be formed by the heel holder housing or connected to the heel holder housing, for example glued. The actuator housing can also be firmly connected to the respective holding element, for example glued. The actuator housings can form locking positions for the abutment elements.

The adjusting structure each comprises an abutment element for the first and the second holding element. The abutment elements can be displaced in the longitudinal direction relative to the respective actuator housing and snap into the predetermined locking positions in the actuator housing. The abutment elements are preferably moved together in the longitudinal direction by an adjusting element in order to move from one locking position to the next locking position. The abutment elements are preferably moved synchronously, that is, in the same direction, over the same distance at the same speed.

The position of the adjusting structure on the coupling sections can determine a force for entering the heel holder and/or a release force of the heel holder, preferably essentially vertically upwards. The release force must be used, for example, when the ski hits hard or in the event of a fall must be overcome in order to release the heel end of the ski boot in the vertical direction from the heel holder. This can prevent injuries or at least reduce the risk of injury.

This means that the adjusting structure can have a first abutment element laterally next to the coupling section of the first holding element and a second abutment element laterally next to the coupling section of the second holding element. The abutment elements preferably have a smooth surface with low frictional resistance. The material of the abutment elements preferably has a small coefficient of elasticity, preferably a coefficient of elasticity that essentially corresponds to or is smaller than an elasticity coefficient of the material of the holding elements or the holding element body. For this purpose, the abutment elements can be formed, for example, from the same material as the holding elements or the holding element body.

The pretensioning force of the pretensioning device can tension the coupling section of the first holding element transversely to the longitudinal axis of the ski binding into a stop contact with the first abutment element and the coupling section of the second holding element transversely to the longitudinal axis of the ski binding into a stop contact with the second abutment element.

The pivot axes can be formed in the stop contact of the coupling sections and the respective abutment element.

The adjusting structure can have a cross member which is guided so as to be displaceable in the longitudinal direction relative to the heel holder housing and, in the plan view, extends above or below the holding elements transversely to the longitudinal direction and preferably laterally beyond the holding elements.

The abutment elements can be connected to the traverse or formed on the traverse and each have a preferably convex round contact surface facing laterally towards the respective coupling section, with which the respective coupling section is in stop contact. The support elements can be rotatably mounted on the traverse.

The heel holder, preferably the heel holder housing, can have a first lateral limit stop for the first holding element and a second lateral limit stop for the second holding element. The first and second limit stops can be formed in a side wall of the heel holder housing facing the toe holder or connected to this side wall.

The first holding element can be in stop contact with the first limit stop in the longitudinal direction between its engagement section and its coupling section and the second holding element can be in stop contact with the second limit stop in the longitudinal direction between its engagement section and its coupling section, so that the holding elements are in particular against the preload force of the Pretensioning device can be pivoted about the respective pivot axis from the stop contact with the respective limit stop.

The limit stops can be part of elongated through openings in the side wall of the heel holder housing facing the toe holder, the respective closed ends of the through openings forming the first limit stop or the second limit stop. The through openings can be arcuate in a plan view from the front of the side wall from the toe holder, but they are preferably straight, each with a single or two or more sections that are at an angle to one another. The through openings extend transversely to the longitudinal direction from a respective inner through opening end at a first distance from the center line in the longitudinal direction of the ski binding away from one another obliquely downwards to an outer through opening end at a second distance from the center line. The second distance is greater than the first distance.

If, as described, the through openings run at an angle to a ski surface, the holding elements are deflected about the respective pivot axis in the Y direction and in the Z direction when vertically triggered. The deflection of the holding elements in the Z direction can be achieved by pivoting the Holding element body takes place or is supported around the radial central axis of the bearing section.

The first holding element can form a two-armed lever around the first pivot axis and the second holding element can form a two-armed lever around the second pivot axis. The levers can each have a front lever arm extending from the associated pivot axis in the direction of the respective engagement section and a rear lever arm extending from the associated pivot axis in the direction of the respective bearing section. By adjusting the adjusting structure, the position of the respective pivot axis and the ratio of the length of the front lever arm to the length of the rear lever arm for the respective holding element can be adjusted.

The pretensioning force of the pretensioning device in the respective bearing section can act in a force introduction point. The length of the front lever arm of the respective holding element can be measured from the associated pivot axis to a free front end of the respective holding element and the length of the rear lever arm of the respective holding element can be measured from the associated pivot axis to the force introduction point of the respective holding element. The respective pivot axis can be adjusted back and forth in the longitudinal direction of the associated holding element to such an extent that the ratio of the length of the front lever arm to the length of the rear lever arm can be increased from a smallest value to a largest value. The leverage ratio of the front lever arm to the rear lever arm can be in a range between, for example, 0.2:1 to 1:5 or in a range between 0.5:1 to 4:1.

The heel holder can further comprise an adjusting element which is coupled to the adjusting structure in such a way that an adjustment of the adjusting element causes the adjustment of the adjusting structure and the adjusting structure is in each adjusting position, for example. B. is fixed due to friction or due to the thread pitch of a thread that causes the adjustment of a screw included in the adjusting element.

The heel holder housing can be moved relative to the base about a vertically directed axis of rotation for a side release of the heel holder against a biasing force, preferably of a further biasing device. Such a trigger device for the side release of a heel holder is from the patent application DE 10 2017 120 702 A1 known to the applicant, which is referred to in this regard.

The Figure 1 shows a heel holder 1 of a ski binding, not shown completely, which further includes a toe holder, not shown, known in the prior art.

The heel holder 1 includes a base 2, which in the exemplary embodiment shown is designed as a slide that can be pushed onto a rail S that can be connected to the ski, not shown. A preferably multi-part heel holder housing 3 projects from the base 2. The heel holder housing 3 can, as shown, consist of a first heel holder housing part 32, a second heel holder housing part 33 and a third heel holder housing part 34. In the exemplary embodiment, the third heel holder housing part 34 forms a cover which can be removably connected to the first heel holder housing part 32 and/or the second heel holder housing part 33. The first heel holder housing part 32 and the second heel holder housing part are with each other and connected to base 2. At least the second heel holder housing part 33 can be formed in one piece with the base 2, for example by die casting or a generative process.

For a side release, the heel holder 1 can rotate about an axis of rotation R in order to release the ski boot when lateral forces occur that are above a set release value for the heel holder 1.

A ski brake B is connected to the rail S, whereby the ski brake B or the brake arms A1, A2 can be set in the position shown for the ascent mode by means of a locking and release mechanism, of which only one release lever H can be seen. For alpine mode, the setting can be canceled using the release lever H, so that the brake arms A1, A2 or their free ends are moved downwards by the mechanism when the pedal P of the ski brake B is free of load.

The heel holder housing 3 comprises a side wall 31 facing the toe holder, not shown, with a first through opening 38 for a first holding element 4 and a second through opening 39 for a second holding element 5. The through openings 38, 39 in the exemplary embodiment run obliquely in the side wall 31 and have straight axial ones Side walls.

The first holding element 4 and the second holding element 5 are part of a holding element body 40 ( Figure 3 ), which is stored within the heel holder housing 3. An engagement section 41 of the first holding element 4 and an engagement section 51 of the second holding element 5 protrude from the heel holder housing 3 in the direction of the toe holder, not shown.

The Figure 2 shows a central longitudinal section through the heel holder 1 Figure 1 . In the sectional view it can be seen that the heel holder housing 3 or the first heel holder housing part 32 forms a receptacle 11 for a bearing section 43 of the holding element body 40.

In the exemplary embodiment, the heel holder housing 3 consists of the first heel housing part 32 and the second heel housing part 33, which are captively connected to one another. The heel holder housing 3 is connected to the base 2 via the second heel housing part 33. Preferably, the second heel holder housing part 33 is connected to the base 2 in such a way that the heel holder housing 3 can rotate relative to the base 2 about the axis of rotation R, which projects vertically from the base 2 in the Y direction.

The second heel housing part 33 includes a link 14 which supports a ball 15. In the exemplary embodiment, the ball 15 can be tensioned against the link 14 by means of a spring element 16, whereby a transverse release force of the heel holder 1 can be adjusted. Such a trigger device for the transverse release of a heel holder is from the patent application DE 10 2017 120 702 A1 the registration ring is known, which is referred to in this regard.

The Figure 2 shows the first holding element 4. The engagement section 41 can be seen from the first holding element 4. The bearing section 43 of the holding element body 40 ( Figure 3 ) is stored and secured in the receptacle 11, so that the holding element body 40 and thus the first holding element 4 and the second holding element 5 can at least not move linearly in the longitudinal direction X relative to the heel holder housing 3.

The third heel holder housing part 34 is connected to the first heel holder housing part 32 and the second heel holder housing part 33. On its underside facing the first heel holder housing part 32, the third heel holder housing part 34 has an engagement structure 34a which projects into the receptacle 11 for the bearing section 43 of the holding element body 40. In the exemplary embodiment, the engagement structure 34a is shaped so that when the third heel holder housing part 34 is mounted, it rests on the holding element body 40 placed in the receptacle and presses it towards the side wall 31.

Above the only partially visible holding element body 40, a part of an adjusting structure 8 is shown, the position of which can be changed in the longitudinal direction X relative to the heel holder housing 3 in order to set a triggering force for releasing the heel holder 1 from a holding engagement with a ski boot heel.

In the exemplary embodiment, the adjusting movement of the adjusting structure 8 can be carried out by an adjusting element 9, which is formed here as a nut 9b which is firmly connected to at least part of the adjusting structure 8 or a thread cut into the adjusting structure 8 in a through opening and a screw 9a. By turning the screw 9a in the nut 9b or the thread, the adjusting structure 8 is moved in or against the longitudinal direction X.

The Figure 3 shows a vertical section through the heel holder transversely to the longitudinal direction The holding elements 4, 5 form the U-beams, the closed end of the U-bow forms the bearing section 43.

The holding elements 4, 5 each include the engagement section 41, 51, which cooperates with a heel end, not shown, of a ski boot in order to securely connect the ski boot to the ski in downhill mode. The bearing section 43 of the holding element body 40 prevents the holding element body 40 from being able to move linearly in the longitudinal direction X relative to the heel holder housing 3. Between the bearing section 43 and the engagement section 41, 51, the holding elements 4, 5 each form a coupling section 42, 52, which cooperates with the adjusting structure 8 or abutment elements 12, 13 of the adjusting structure in order to define pivot axes B4, B5. The abutment elements 12, 13 can be displaced by the adjusting member 9 in the longitudinal direction By moving the abutment elements 12, 13, the position of the respective pivot axis B ₄ , B ₅ shifts and this changes the internal restoring force F of the holding element body 40, which must be applied to trigger the heel alternator 1 transversely.

While the abutment elements 12, 13 can be moved in the longitudinal direction, the actuating element housings 81a, 82a are held stationary in the heel holder housing 3 or are firmly connected to the holding elements 4, 5 in the area of the respective coupling section 42, 52. The actuator housings 81a, 82a can include locking positions in which the abutment elements 12, 13 can lock when they are moved in the longitudinal direction X. Each of the locking positions represents a different position of the respective pivot axis B ₄ , B ₅ and thus a different triggering force for the heel holder 1. The triggering force for each of the different locking positions in the production of the heel holder 1 is preferably known, for example determined or determined through tests calculated according to the known sizes.

It does not need to be emphasized that the actuating element housings 81a, 82a and locking positions for the abutment elements 12, 13 lie opposite one another in mirror symmetry with respect to a central longitudinal axis of the holding element body 40 or the heel holder 1 and the abutment elements 12, 13 are moved synchronously in the longitudinal direction X. The adjusting elements 81, 82 are preferably formed on an outside of the holding elements 4, 5 facing away from the central longitudinal axis of the holding element body. In one embodiment, the actuating element housings 81a, 82a can be pushed or clipped onto the holding elements 4, 5 in the area of the respective coupling section, glued to the respective holding elements 4, 5, for example, or in the heel holder housing 3 against movement relative to the respective holding elements 4, 5 be secured non-positively or positively.

In one embodiment, the locking positions can also be formed directly by the holding elements 4, 5. These can be elevations, troughs or notches that are formed or formed directly from the material of the holding elements 4, 5.

The Figure 4 shows a sectional view of the heel holder 1 without the heel holder housing 3 in a plane that intersects the central longitudinal axis of the first holding element 4 perpendicular to the longitudinal axis X. Of the holding element body 40, only the holding element 4 and part of the storage area 43 can be seen. The holding element 4 includes the engagement section 41 and the coupling section 42. In The adjusting element 8, which is connected to the adjusting element 9, is arranged in the area of the coupling section 42.

In the Figure 4 the pivot axis B ₄ is shown, about which the holding element 4 or the section of the holding element ₄ lying in front of the pivot axis B 4 in the direction of the toe holder can be pivoted. The pivot axis B ₄ divides the holding element 4 into a first lever arm H1 and a second lever arm H2. The lever arm H1 extends from the pivot axis B ₄ to the transition of the holding element 4 over a length L1 into the bearing section 43 of the holding element body 40 and includes a part of the coupling section. The second lever arm H2 extends from the pivot axis B ₄ to the free end of the holding element 4 over a length L2 and includes a part of the coupling section 42 and the engagement section 41. The length L1, L2 of the respective lever arm H1, H2 or the ratio The lever arm lengths relative to each other are determined by the position of the pivot axis B ₄ on the coupling area 42 of the holding element 4. The smaller the aspect ratio H2:H1, the greater the force required on the engagement section 41 to pivot the lever arm 4 or the second lever arm H2 about the pivot axis _B4 .

It can also be seen from the figure that the rail S is firmly connected to the ski body, not shown, and in the exemplary embodiment it is connected by means of screws. In the Figure 3 For example, four screws are shown, two on each side of the heel holder 1, which are arranged mirrored with respect to a central longitudinal axis of the heel holder 1.

The Figure 5 shows a view from above of the heel holder housing 3 with the heel holder housing parts 32, 33 and next to it the heel holder housing part 34. The underside of the heel holder housing part 34 can be seen, which rests directly on the heel holder housing part 32 when the heel holder housing part 34 closes the heel holder housing 3 (see Figure 2 ).

The receptacle 11 for the bearing section 43 of the holding element body 40 is formed in the heel holder housing 3. The shape of the receptacle 11 essentially corresponds to the shape of the bearing section 43. The width of the receptacle 11 essentially corresponds to the diameter of the holding element body 40 in the area of the bearing section 43. The receptacle 11 is shaped such that the holding element body 40 lying in the receptacle 11 essentially cannot be displaced in the longitudinal direction X.

The third heel holder housing part 34 forms a cover of the heel holder housing 3. It comprises an engagement structure 34a, the shape of which essentially corresponds to the shape of the receptacle 11 in the heel holder housing 3. The engagement structure 34a can be a bead-shaped elevation or also a receptacle in the form of a groove for a part of the bearing section 43 of the holding element body 40. The engagement structure 34a is preferably bead-shaped and engages in the receptacle 11 in the heel holder housing 3 when the third heel holder housing part 34 is connected to the Heel holder housing 3 is connected. As the Figure 2 shows, the engagement structure 34a can be shaped so that it tensions the holding element body 40 in the longitudinal direction X towards the toe holder. The engagement structure 34a can rest on the holding element body 40 in the area of the bearing section 43, so that the holding element body 40 is fixed transversely to the longitudinal direction at least in this area.

The engagement structure 34a can rest on the bearing section 43 of the holding element body 40 only in one point or a section, namely in a point or section that defines a pivot axis transverse to the longitudinal direction and at least substantially parallel to a ski surface about which the holding element body 40 pivots can if the holding elements 4, 5 are moved outwards and upwards in the through openings 38, 39 in the side wall 31 of the heel holder housing 3 when the heel holder 1 is triggered.

The Figure 6 shows two views of the heel holder 1 with different positions of the pivot axes B ₄ , B ₅ . The respective position of the pivot axes B ₄ , B ₅ determined the length ratio of lever 1 to lever 2 ( Figure 4 ) and thus the force that is necessary for a vertical release of the ski binding or the heel holder 1.

In the right representation of the Figure 6 the pivot axes B ₄ , B ₅ are in a position that determines or defines the minimum triggering force. Lever 2 has a maximum length L2, lever 1 has a minimum length L1.
