The invention relates to a heel holder for a combined downhill and touring binding for a ski. The heel retainer includes a base plate for connecting the heel retainer to a top of the ski, a connection structure, a tensioning device for securely holding a ski boot in the heel retainer with a sole retainer and a locking mechanism that selectively locks at least portions of the heel retainer in a downhill or touring position. The heel holder further has a pressure body which biases at least parts of the heel holder in the downhill position. The connection structure consists of two separate parts, which are connected to one another in such a way that they can be moved transversely relative to the skiing direction in the case of a transverse release of the heel holder relative to each other. The invention further relates to a ski with a ski binding with a heel holder according to the invention.

The EP 2 351 603 A2 relates to a combined alpine and touring binding for a ski with a toe unit and a heel unit. The heel unit comprises a bearing structure and a heel holder. The heel holder is movably mounted on the bearing structure and can be fixed in an alpine position and in a touring position on the bearing structure.

The EP 0 254 829 A2 relates to a safety binding with a pivotable but not liftable sole plate. The front portion of the sole plate carrying the toe piece is coupled to a guide plate which is displaceable in the ski longitudinal guide rails of a base plate but can not be lifted in the vertical direction. The base plate can pivot in the event of transverse forces in a plane parallel to the ski surface and thereby cause a transverse release of the bond on the heel holder.

It is an object of the invention to provide a heel holder for a combined downhill and touring binding, which allows a simple, fast and reliable adjustment of the binding on the ski from the downhill to the touring position, and at the same time a safe solution of the ski boot from the binding guaranteed at a transverse trip. Another task is to provide a ski with downhill and touring binding.

These objects are achieved by the subject matter of claim 1 and claim 13.

The invention relates to a heel holder for a combined downhill and touring binding for a ski, comprising a base plate for connecting the heel holder to a top of the ski, a connection structure and a tensioning device with a sole holder, for securely holding a ski boot in the heel holder.

The base plate is a basic structure that can be fixedly connected to the ski or connected, for example integrated into the ski surface. The Base structure can be made in one piece and used to connect a toe holder and the heel holder to the ski. The base structure may alternatively comprise at least two parts, one connecting the toe holder and another the heel holder to the ski.

The connection structure comprises a first connection structure part and a second connection structure part, wherein the first connection structure part is connected or connectable in a pivot axis with the tensioning device, and the second connection structure part is connected to the base plate, so that it can be moved on the base plate in and against a skiing direction. The first connection structure part is in guiding engagement with the second connection structure part, and may be, e.g. in a transverse release of the heel holder, are moved while driving in the guide transversely to the skiing direction on the second connection structure part.

Further, the heel holder includes a locking mechanism that selectively locks at least portions of the heel holder in a downhill or riding position or in a walking position, and a press body.

Hereinafter, the parts of the heel holder that can be moved from the driving position to the walking position are also referred to as heel holders for a short time, to make it easier to read the application. It will be understood, however, that the heel retainer comprises a total of more parts, such as the base plate, which are not included in the parts of the heel holder of claim 1 which are lockable by the locking mechanism in either the riding position or the walking position. A ski brake may also be connected to the heel holder, which is then moved together with the heel holder from the walking position to the driving position, and vice versa.

According to the invention, the locking mechanism comprises a locking lever which selectively locks the connecting structure in the driving position and the walking position.

The tensioning device is a known tensioning device with a sole holder which clamps the heel holder in a holding position in which the ski boot is securely connected to the ski. To get out and to get into the ski or in the ski binding in the driving position, the tensioning device can be relaxed, so that the heel holder releases the ski boot.

The parts of the heel holder which the locking mechanism selectively locks in the riding position or the walking position are inter alia, e.g. around the connection structure, the tensioning device and parts of the locking mechanism of the heel binding.

By the operation of the locking lever, i. if the locking lever is e.g. is pressed by a ski pole tip in the direction of the surface of the ski, the locking of the heel holder dissolves in the driving position and the second connection structure part can be moved on the base plate against the skiing direction.

In a transverse release of the heel holder, the first connection structure part can solve transversely to the ski direction of the second connection structure part and at the same time release the locking of the heel holder by the locking lever, so that the second connection structure part can move on the base plate against the skiing direction.

The locking lever may be connected to the connecting structure, in particular the second connecting structure part in a pivot joint with a pivot axis which runs parallel and transverse to the ski surface. The locking lever may be formed in one piece, or consist of two or more separate partial levers, each of the partial lever forms a lever arm, and the two lever arms in the pivot joint are preferably connected at an angle. The locking lever may be made of a plastic, a reinforced plastic or a metal, or comprise one or more of these materials.

Preferably, the locking lever on two separate lever arms, a first lever arm, which can be operated for example with the tip of a ski pole for releasing the lock, and a second lever arm, which is part of the locking mechanism. In the case of two separate lever arms, the first lever arm can have an extension at its end which preferably forms the pivot joint, which engages under the second lever arm and thereby prevents the second lever arm in the pivot joint from pivoting relative to the first lever arm when the first lever arm is actuated.

The locking lever and the second lever arm have a clearly defined underside, which faces the ski surface, and a surface facing in the opposite direction. Perpendicular to the surface protrudes from a support member which rotatably holds on its, of the locking lever and the second lever arm, pioneering side two rollers about their common axes of rotation. The two rollers can sit on ends or end portions of the common axis of rotation and each have a finite distance. The length of the support is chosen so that the rollers can cooperate with the first connection structure part to release the locking of the locking lever. For this purpose, the first connection structure part on a slotted guide, which can move the rollers in a direction perpendicular away from the ski surface at a transverse release of the heel holder. In order to be able to engage in the first connection structure part, the second connection structure part has an opening, through which the rollers protrude into the first connection structure part, and thus can engage in the first connection structure part.

As a slide guide here is meant in particular a guide, such as a curved guide, which changes the direction of movement of a guided part, for example, a movement in a coordinate system along an x-direction superimposed by a movement in a y- and / or z-direction.

In a transverse release of the heel holder, in which the first connection structure part in the guide is moved transversely to the skiing direction out of the guide with the second connection structure part out, the rollers are raised by the guide rail formed in the first connection structure part for the rollers. Since the rollers are connected via the support fixed to the locking lever and the second lever arm, the locking lever and the second lever arm is also raised. This causes a solution of the locking of the heel holder in the driving position, so that the heel holder moves after or during the transverse release and from the driving position to the walking position, which allows a particularly safe release of the ski boot from the ski binding.

On its underside, the locking lever or the second lever arm may have at least one counter-engagement element which cooperates with an engagement element for selectively locking the heel holder in the driving position and in the walking position. The Engagement element may be connected to the pressure body or the base or one of the structural parts, it is preferably formed in one piece with the Andruckkörper, depending on the material, for example by injection molding, by deformation of a metal plate in a press, by a sintering process, or other known in the art suitable shaping methods.

Alternatively, the engagement element may be firmly connected to the pressure body, e.g. glued, soldered, welded or screwed on rivets or other means or the pure shape positively and / or non-positively connected.

The engagement element and the counter-engagement element can each be a toothing, wherein the mating connection element is preferably formed on a front end region of the locking lever in the direction of skiing or on the underside of the second lever arm. For locking the heel holder, the counter-engagement element on the locking lever or the second lever arm can engage in the engagement element on the pressure body. Besides a tooth engagement, the lock may also be e.g. be formed by a pin which can engage in different recesses, or other known in the art and suitable locks for the purpose.

The engagement member has at least two engagement positions, a first engagement position engaged by the counter-engagement member to lock the heel retainer (s) in the drive position, and a second engagement position engaged by the counter engagement member to engage the heel retainer To lock parts of the heel holder in the walking position. In this case, the counter-engagement elements in the driving or walking position can also engage in the space directly in front of or behind the engagement element. That is, a lock according to the invention is also given if the engagement element and the counter-engagement element are not in direct engagement with each other, but in their respective position to each other determine the heel holder in the driving or walking position.

The locking lever or the second lever arm may be biased by a spring element, which is supported on the locking lever or the second lever arm and on a lower side, for example, of the connecting structure, in an engagement direction with the engagement element on the pressure body. That is, the spring element or the spring force of the Spring element pushes the counter-engagement element in the locking position with the engagement element and thus locks the counter-engagement element in or on the engagement element optionally in the driving position and in the walking position, so that the lock when driving, walking or during transport can not unintentionally solve.

The spring element may be a spiral spring, a leaf spring or an elastic solid body or hollow body, with or without filling. Incidentally, this applies to all spring elements which are mentioned in the description.

The spring element preferably rests on the end remote from the pivot end of the top of the locking lever or the second lever arm, which adjoins the region with the counter-locking element. For this purpose, the locking lever or the second lever arm may have on its upper side a guide for the spring element, so that the spring element can not slip off the locking lever or the second lever arm. At an end facing the rear end of the ski in the skiing direction, the locking lever or the first lever arm may have an engagement recess into which a ski pole tip can engage to press the locking lever onto the ski surface by means of the ski pole, thereby compressing the spring element and thereby the counter locking element is released from the lock with the locking element. Triggering of the locking lever can, as already described above, also be effected by a transverse release of the heel holder.

The pressure body is connected to the base plate so that the pressure body with the engagement member when driving, walking or transport can not move relative to the base plate. The pressure body and the engagement element of the locking mechanism may be disposed between the base plate and the connection structure and the second connection structure part.

In order that the heel holder can be repeatedly moved in the driving position and in the walking position, the pressure body can be pressed against a front stop formed in the ski direction, so that the heel holder in the driving position, for example, with an inner side of the rear wall of the second connection structure part in the skiing direction an outer wall of a rear in the ski rear wall of the pressure body, can not be moved beyond the driving position in the skiing direction. This stop can be formed for example in or on the base plate.

To press the contact body against the stop, the heel holder can be a z. B. cylindrical holding element having an attached or molded external thread, wherein the external thread or the spirally extending webs of the external thread can engage in grooves formed in the base plate / can. The external thread or the hollow cylinder can be screwed into engagement with the grooves in a desired position quasi. A spring element which is supported on a front end of the holding element in the skiing direction and on an inner wall of the pressure body, presses the holding element counter to the skiing direction, so that the flanks of the thread are pressed against the flanks of the grooves, which is prevented by the adhesion Holding element eg by vibration of the ski on departure independently from its adjusted position moves.

The spring element simultaneously forms a pressure spring for the heel holder against the resistance of the connection structure when entering the ski boot in the heel holder or the ski binding can be moved by a few millimeters against the direction of the ski. Even if the ski is slightly bent when driving in the longitudinal direction, the spring element allows an adaptation of the ski binding to the usually not flexible ski boot sole.

In order to move the heel holder from the driving position to the walking position, the heel holder has a spring element, which is supported at its front end in the skiing direction on a strut, which is connected to the pressure body, preferably formed with the pressure body in one part. At the other end, the spring element is supported on an inner side of the rear wall in the skiing direction of the second connection structure part. In the driving position, the spring element is compressed between the two supports and locks the heel holder by means of the locking mechanism in the driving position. Now, if the lock is released by a movement of the locking lever, the spring element can expand and thereby push the second connection structure part, together with the other associated components, away from the substantially stationary strut on Andruckkörper away against the skiing direction in the walking position.

The locking lever may be connected in the pivot joint with the connecting structure. It forms, as described above, a first and a second lever arm, wherein the first lever arm from the pivot to the spring element holder, which biases the locking lever into the locking position, and beyond, and the second lever arm of the pivot joint until the intervention for the ski pole and beyond. In this case, the second lever arm is preferably longer than the first lever arm, which leads to an amplification of the force acting on the spring element unlocking force when the first lever arm is pressed in the direction of the ski surface. As already stated, the locking lever can be formed in one piece or consist of several separate partial levers.

The locking lever may protrude rearward from the heel cup or connection structure to be actuated with the tip of the ski pole, and less preferably, the locking lever may protrude laterally from the heel cup or connection structure and / or be hinged to the heel cup or connection structure issue. The e.g. The locking lever which can be folded down with the ski pole can be prestressed with a spring element in the position folded onto the heel holder. For protection against excessive contamination and damage, the locking lever or the part of the first lever arm projecting from the connecting structure can be protected by a bracket, wherein the bracket can be connected to the second connecting structure part.

The triggering force for the transverse release can be adjusted by means of a triggering device, wherein the triggering device has a spring-loaded roller, which can be moved in a backdrop transverse to the skiing direction. The backdrop can be connected to the second connection structure part or integrally formed. The shape of the gate and the adjustable spring force of the spring element acting on the roller determine the height of the lateral release force for triggering the transverse release of the heel holder.

The heel holder may comprise at least one climbing aid, which can be pivoted from a secured position in the departure position in a touring position. The climbing aid can be held by a spring element in the secured position during departure and / or in the tour position.

The heel holder preferably has at least two climbing aids, wherein the first climbing aid supports the ski boot in a first climbing angle, and the second climbing aid supports the ski boot in a second climbing angle different from the first climbing angle. The climbing aid or the climbing aids can be secured by a respective spring element or a common spring element in the secured position while driving. The same applies to a backup in the walking position. Preferably, the two or more climbing aids can be successively pivoted into the walking position, starting with the climbing aid with the lowest climbing angle.

The invention further relates to a ski with a ski binding with the above-described heel holder.

An exemplary embodiment of a heel holder is shown below with reference to FIGS. All features essential to the invention shown in the figures belong to the scope of the invention and can individually or in the combinations shown, advantageously further develop the invention.

The FIG. 1 shows an exploded view of an embodiment of a heel holder 1 of a ski binding. The heel holder 1 has a base plate 2, a first Connection structure part 3a and a second connection structure part 3b, which together form a connection structure 3, on.

The first connection structure part 3a has an engagement structure on its underside facing the second connection structure part 3b, and the second connection structure part 3b has a counter-engagement structure to the engagement structure on its upper side facing the first connection structure part 3a. The engagement structure can be inserted from the side transverse to the skiing direction in the counter-engagement structure, so that the first connection structure part 3a forms a carriage with runners, which are guided in rails of the counter-engagement structure. The carriage or the connecting structure part 3a can move transversely to a skiing direction and thus move in the lateral direction on / to the second connection structure part 3b or separate from the second connection element 3b in the case of transverse release of the ski binding.

The first connection structure part 3a includes a footrest support surface 26 for a ski boot. The footprint 26 has a plurality of roller bodies 27 on which the ski boot sole snaps, and which are rotatably mounted, so that the ski boot is not retained by friction forces in a transverse release of the binding. On the roller bodies 27, a slide plate may be arranged, e.g. Teflon-coated.

A tensioning device 4 in a pivot joint 9 is connected to the first connection structure part 3a. The tensioning device 4 comprises inter alia a tensioning device body 4a, a sole holder 5 and two climbing aids 7, 8.

The second connection structure part 3b can be moved linearly in and against the skiing direction in the base plate 2 and, in the skiing direction, has an extension 25 with a hook-shaped front end 25a. The extension 25 forms a holding device for a ski brake, not shown, which releases the ski brake in the driving position and secures against triggering in the walking position.

In the exemplary embodiment, the second connection structure part 3b also forms a housing for a triggering device 11 for setting a release force for a transverse release of the heel holder 1 with a roller 11a, which is guided in a slot on the second connection structure part 3b.

Between the base plate 2 and the second connection structure part 3b, a pressure body 13 is arranged, which shows a toothing 14 integrally formed in the exemplary embodiment.

A locking lever 15, which in the exemplary embodiment has a first lever arm 15a and a second lever arm 15b, has a counter-toothing 23 on one underside of the second lever arm 15b facing the ski surface, the teeth of which can interact with the toothing 14 to selectively engage the heel holder 1 in the Driving position and in the walking position to lock.

The first lever arm 15a and the second lever arm 15b are shown in the example as separate components that can be connected together in a pivot joint 16. In this case, the first lever arm 15a has an extension projecting beyond the pivot joint, which can engage under the second lever arm 15b and thereby prevents the first lever arm 15a from pivoting relative to the second lever arm 15b when loaded.

The lock lever 15 is connected to the second connection structure part 3b in a pivot joint. The second lever arm 15b has at its top a vertically upwardly projecting support 10, which has at its pointing away from the top of the second lever arm 15b end two rollers 6, which are rotatably mounted on or in the support 10.

The support 10 extends through an opening in the second connection structure part 3b to the first connection structure part 3a. The rollers 6 are far enough into the first connection structure part 3a that they are engaged by a slide guide 12 during a movement of the first connection structure part 3a and moved in a direction perpendicular to the ski surface by the slotted guide 12, which forms a kind of ramp for the rollers 6 can be.

A spring element 17 can be supported on the locking lever 15 or the upper side of the second lever arm 15b and on an underside of the second connecting structure part 3b, thereby pressing the counter-toothing 23, for example, into the toothing 14. So that the spring element 17 does not slip on the second lever arm, there is a cylindrical or truncated cone-shaped guide for the spring element 17 is formed, which can be encompassed by the spring element 17 in the embodiment.

The first lever arm 15a has, at its end facing away from the pivot 16 end an engagement recess into which the skier can engage with a ski pole to press the locking lever 15 on the ski surface, whereby the spring element 17 compresses and the locking of the counter teeth 23 with the toothing 14 is solved.

The pressure body 13 has a semi-cylindrical receptacle for a holding element 19. The holding element 19 has a cylindrical holding element body, which has an external thread 20 at a front end in the skiing direction, which can engage in a screwing manner in grooves or slots 2a of the base plate 2, so that the holding element 19 can not move by itself relative to the base plate 2.

A spring element 21, e.g. is supported on a front in the skiing direction inner wall of the pressure body 13 and the inner wall facing the end of the holding member 19, presses the heel holder 1 in the driving position in which he with an inner side, the rear wall in the ski rear direction of the second connection structure part 3b, on a rear outer wall of the Press body 13 is applied, and at the same time presses the flanks of the external thread 20 against the sides of the groove or slots 2a, and thereby produces an additional adhesion between the pressure body 13 and the base plate 2.

Another spring element 22 is supported on a transverse strut 24, which is integrally formed on the receptacle 13a of the pressure body 13, and on the inside of the rear wall of the connection structure part 3b. The spring element 22 is compressed when the heel holder 1 is in the departure position and is locked in this position by the locking lever 15. If now the locking lever 15 is actuated with the ski pole, so that the lock is released, the spring element 22 or the release spring 22 moves the heel holder 1 counter to the skiing direction relative to the base plate 2. That is, the heel holder 1 is linearly offset backwards on the ski, whereby the sole holder 5 no longer presses the ski boot sole against the ski and the ski boot heel can be lifted unhindered for the walking movement of the ski surface. The movement of the heel holder 1 in the walking position ends in the embodiment shown, when an inside of a in Skiing direction front wall of the second connection structure part 3b on an outer side of a front wall of the Anrückkörpers 13 abuts

If, due to a transverse release of the ski binding, the first connection structure part 3a is moved transversely to the skiing direction and thereby the rollers 6, the support 10 and the second lever arm 15b are moved in a direction perpendicular away from the surface, thereby locking between the engagement element 14 and the Counter-engagement element 23 is released, so that substantially simultaneously with the movement of the first connection structure part 3a transversely to the skiing direction of the heel holder 1 is unlocked and moved from the driving position to the walking position. This ensured a safe separation of the ski from the user when a transverse release of the ski binding or the heel holder 1 occurred.

The FIG. 2 shows a perspective view of the assembled heel holder 1 of FIG. 1 , The locking lever 15 and the first lever arm 15a protrude beyond the rear end of the heel holder 1 in the skiing direction, so that the first lever arm 15a is easily accessible to a ski pole and can be pressed onto the ski surface (not shown) by means of the ski pole. Good to see is the ramp-shaped end of the slide guide 12 which ensures that in a transverse release of the heel holder 1, wherein the first connection structure part 3a moves in the guide in the second connection structure part 3b in the arrow direction, the rollers 6 and thus the second lever arm 15b so far can be raised, that the locking of the heel holder 1 is released in the running position, and the heel holder 1 and the second connection structure part 3b can be pressed by the spring element 22 in the walking position.

The FIG. 3 shows a longitudinal section through the heel holder 1 of FIG. 1 at the level of the locking mechanism in the driving position. The connection structure parts 3a, 3b are in their foremost position, in which the ski can be used for a ride or downhill. In this position, the sole holder 5 presses the ski boot on the ski. The locking lever 15 and the second lever arm 15b with the counter-toothing 23 is in engagement with the toothing 14, and thereby locks the heel holder 1 in the driving position. The spring 17, which is supported on an inner wall of the second connection structure part 3b and on the second lever arm 15b in an area in the ski direction in front of the toothing 23, presses the second lever arm 15b and the counter toothing 23 in the toothing 14 and locked the locking lever 15 in this position. In the exemplary embodiment, the pressure body 13 protrudes in the driving position of the heel holder 1 to the rear from the connecting structure part 3b, the second lever arm 15b is arranged next Andruckkörper 13. The rollers 6, which are rotatably connected to the support 10 about its rotation axis, project into the first connection structure part 3a through an opening in the second connection structure part 3b.

The FIG. 4 shows the heel holder 1 of FIG. 3 in the walking position. The only difference between the two FIGS. 3 and 4 is that the locking of the heel holder 1 has been released, so that the non-visible spring element 22 could press the heel holder 1 from the driving position against the skiing direction in the walking position. The positions of the first connection structure part 3a, the second connection structure part 3b, the trigger device 11, the rollers 6 and the lock lever 15 to each other have not changed since they have all been moved together from the driving position to the walking position.

To get from the driving position to the walking position of the heel holder 1 has been moved on the ski linearly opposite to the skiing direction. To do this, for example, the skier had to insert the tip of a ski pole into the engagement recess on the first lever arm 15a and press the locking lever 15 onto the ski surface. This will be in the FIG. 3 shown locking between the toothing 14 and the counter-toothing 23 solved and the heel holder 1 can be moved on the ski against the direction of travel to the rear.

In the FIG. 4 is the heel holder 1 in the locked walking position in which an inner side of a front in the skiing direction wall of the second connection structure part 3b abuts an outer side of a front in the skiing direction wall of the pressure body 13, and the counter teeth 23 on the second lever arm 15b by the spring element 17 behind the teeth 14 is pressed into a locking position. Alternatively, the toothing 14 may also be formed so that the counter-toothing 23 engages in the driving position and in the walking position in the toothing 14 for locking the heel holder 1 in the respective position.

The FIG. 5 shows a longitudinal section through the heel holder 1 of FIG. 2 in a plane with the central axis of the triggering device 11 in the driving position. The spring element 22 is in the driving position shown between the transverse strut 24 and an inner side of a in Skilaufrichtung caught rear wall of the second connection structure part 3b. The heel holder 1 is locked in the driving position.

The FIG. 6 shows the spring element 22 or the release spring after the lock of the heel holder 1 has been released in the driving position and the heel holder 1 has been pressed into the walking position. The spring element 22 has thereby pressed the heel holder 1 and the second connection structure part 3b and the parts connected thereto on the ski to the rear, so that the heel holder 1 is now in the walking position, as in FIG. 4 shown, locked.

The FIG. 7 shows a section through the heel holder 1 of FIG. 1 parallel to the ski surface in a plane with the central axis of the triggering device 11. The rollers 6 protrude through the opening in the second connection structure part 3b into the first connection structure part 3a. The triggering force of the heel holder 1 for a transverse release can be determined by the triggering device 11 by applying a pressure to the roller 11a by compressing the in the triggering device caught spring element 18 can be varied.
