Description

technical field

The invention relates to a fastening device for fastening a binding unit of a ski binding, in particular a front unit of a ski binding and/or a heel unit of a ski binding, on a ski and for adjusting a position of the binding unit of the ski binding in the longitudinal direction of the ski relative to the ski. This fastening device comprises a base unit for fastening the fastening device on the ski, a binding holding unit to which the binding unit can be fastened, the binding holding unit being mounted on the base unit so that it can be displaced along a longitudinal axis of the base unit relative to the base unit from a first position to a second position and back or and a locking device for releasably locking the binding holding unit in the first position of the binding holding unit along the longitudinal axis of the base unit relative to the base unit and in the second position of the binding holding unit along the longitudinal axis of the base unit relative to the base unit.

State of the art

Fastening devices, which belong to the technical field mentioned at the outset, are known. For example, describes the DE 10 2016 123 488 A1 Marker Deutschland GmbH such a fastening device.

Such fastening devices have the disadvantage that they have very complex and sometimes very filigree elements, which can only be produced with complex processes and thus complex and costly to a stable To allow attachment of a binding unit of a ski binding on a ski. In addition, such fastening devices are mostly very awkward to use.

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

Presentation of the invention

The object of the invention is to create a fastening device belonging to the technical field mentioned at the outset, which can be manufactured simply and inexpensively, is easy to operate and enables a binding unit of a ski binding to be fastened very stably on a ski.

The solution to the problem is defined by the features of claim 1. According to the invention, the locking device has two locking elements which, on a first unit of the base unit and the binding holding unit, can be moved from a locking position to a release position and back are mounted or can be mounted such that they can be moved, with the two locking elements in the locking position each forming a positive connection with a second unit of the base unit and the binding holding unit in order to hold the binding holding unit in the respective first position of the binding holding unit along the longitudinal axis of the base unit relative to the base unit and the second position of the binding holding unit along the longitudinal axis of the base unit relative to the base unit, wherein in the release position of the two locking elements the positive connection of the two locking elements with the second unit of the base unit and the binding holding unit is released so that the binding holding unit can be moved along the longitudinal axis of the Base unit can be moved relative to the base unit from the first position to the second position and back.

According to the invention, the fastening device comprises a base unit for fastening the fastening device on the ski. This base unit is preferably a base plate for attaching the fastening device to the ski. Alternatively, however, the base unit can also be designed in a manner other than in the form of a base plate.

According to the invention, the fastening device comprises a binding holding unit to which the binding unit can be fastened, wherein the binding holding unit is mounted or can be mounted on the base unit so that it can be displaced along a longitudinal axis of the base unit relative to the base unit from a first position into a second position and back. When the fastening device is fastened to the ski, the longitudinal axis of the base unit is preferably aligned in the longitudinal direction of the ski, with a binding unit or a front unit and/or a heel unit of a ski binding being able to be or being mounted on the ski by means of the fastening device.

According to the invention, the locking device has two locking elements which are mounted or can be mounted on a first unit of the base unit and the binding holding unit so that they can be moved from a locking position into a release position and back. In other words, when the fastening device is in the installed state, these two locking elements are preferably mounted on the first unit of the base unit and the binding holding unit so that they can be moved from the locking position to the release position and back.

According to the invention, the two locking elements in the locking position each form a positive connection with a second unit of the base unit and the binding holding unit in order to hold the binding holding unit in the respective first position of the binding holding unit along the longitudinal axis of the base unit relative to the base unit and the second position of the binding holding unit along the longitudinal axis of the base unit relative to the base unit and thereby to prevent a sliding movement of the binding holding unit along the longitudinal axis of the base unit relative to the base unit away from the first position or from the second position. Preferably, the second unit of the base unit and the binding holding unit is the other of the base unit and the binding holding unit than the first unit of the base unit and the binding holding unit. That is, when the first unit of the base unit and the binding-holding unit is the base unit, the second unit of the base unit and the binding-holder unit is preferably the binding-holder unit, while when the first unit of the base unit and the binding-holder unit is the binding-holder unit, the second unit of the base unit and the Binding retention unit is preferably the base unit.

Due to the two locking elements and their form-fit connection with the second unit of the base unit and the binding holding unit in the locking position, a binding unit of a ski binding can be attached very stably to a ski in a simple manner. In addition, the two locking elements can also be designed with shapes that are easy to manufacture, so that the fastening device can be manufactured simply and inexpensively. In addition, a form-fitting connection can be formed and broken again in a simple manner. This ensures that the fastening device can also be operated easily.

In the locking position, the two locking elements preferably interact in a form-fitting manner in one direction of the longitudinal axis of the base unit with the first unit of the base unit and the binding holding unit and each form the form-fitting connection with the second unit of the base unit and the binding holding unit in order to hold the binding holding unit in the respective one of the first position of the binding holding unit along the longitudinal axis of the base unit relative to the base unit and the second position of the binding retention unit along the longitudinal axis of the base unit relative to the base unit. In other words, the two locking elements are preferably positioned in the locking position relative to the first unit of the base unit and the binding holding unit in such a way that a movement of the two locking elements relative to the first unit of the base unit and the binding holding unit in a direction of the longitudinal axis of the base unit due to a positive fit of the two locking elements with the first unit of the base unit and the binding holding unit is prevented. This has the advantage that, together with the positive connection of the two locking elements with the second unit of the base unit and the binding holding unit, a very stable, releasable locking of the binding holding unit in the first position of the binding holding unit along the longitudinal axis of the base unit relative to the base unit is easily achieved and in the second position of the binding retention unit can be achieved along the longitudinal axis of the base unit relative to the base unit.

As an alternative to this, however, there is also the possibility that the two locking elements in the locking position do not interact in a form-fitting manner with the first unit of the base unit and the binding holding unit in a direction of the longitudinal axis of the base unit. For example, the two locking elements can be held in the locking position by a non-positive connection in one direction of the longitudinal axis of the base unit relative to the first unit of the base unit and the binding holding unit, and each form the positive connection with the second unit of the base unit and the binding holding unit in order to To lock the binding holding unit in the respective first position of the binding holding unit along the longitudinal axis of the base unit relative to the base unit and the second position of the binding holding unit along the longitudinal axis of the base unit relative to the base unit.

Advantageously, the two locking elements are mounted or can be mounted so as to be movable essentially horizontally relative to the base unit on the first unit of the base unit and the binding holding unit from the locking position into the release position and back. This has the advantage that the two locking elements can be designed to be adjustable from the locking position into the release position and back in a simple manner.

In addition, the fastening device can be designed in a simple manner in such a way that the two locking elements in the locking position interact in a form-fitting manner in a direction of the longitudinal axis of the base unit with the first unit of the base unit and the binding holding unit, which means that a very stable, releasable locking of the binding retention unit can be achieved in the first position of the binding retention unit along the longitudinal axis of the base unit relative to the base unit and in the second position of the binding retention unit along the longitudinal axis of the base unit relative to the base unit.

In a variant of this, there is also the possibility that the two locking elements are not mounted or can be mounted so that they can be moved from the locked position to the release position and back, relative to the base unit on the first unit of the base unit and the binding holding unit.

Both when the two locking elements are mounted or can be mounted substantially horizontally relative to the base unit on the first unit of the base unit and the binding holding unit from the locked position to the release position and back, and when the two locking elements are not substantially horizontal relative to the base unit on the first unit the base unit and the binding holding unit are mounted or can be mounted such that they can be moved from the locking position to the release position and back, the two locking elements are advantageously substantially perpendicular to the longitudinal axis of the base unit relative to the base unit on the first unit of the base unit and the binding holding unit from the locked position to the release position and back movable stored or storable. This has the advantage that the two locking elements can easily be brought into the form-fitting connection with a second unit of the base unit and the binding holding unit in the locking position and that the form-fitting connection with the second unit of the base unit and the binding holding unit when adjusting in the release position can be dissolved again in a simple manner.

In a variant of this, there is also the possibility that the two locking elements are not substantially perpendicular to the longitudinal axis of the base unit relative to the base unit on the first unit of the base unit and the binding holding unit are mounted or can be mounted such that they can be moved from the locking position into the release position and back.

As an alternative to these variants, however, there is also the possibility that the two locking elements can neither be moved essentially horizontally relative to the base unit on the first unit of the base unit and the binding holding unit from the locked position to the release position and back nor essentially perpendicular to the longitudinal axis of the base unit relative to the base unit are mounted or can be mounted on the first unit of the base unit and the binding holding unit so as to be movable from the locking position to the release position and back.

Advantageously, the two locking elements are mounted or can be mounted on the first unit of the base unit and the binding holding unit from the locking position into the release position and back so that they can be displaced along an adjustment path. In the mounted state of the fastening device, the two locking elements are thus preferably mounted so as to be displaceable along the adjustment path. For this purpose, the two locking elements are preferably each designed as a carriage, which is slidably mounted on the first unit of the base unit and the binding holding unit. This has the advantage that the two locking elements are mounted or can be mounted in a stable, movable manner in a simple manner. However, the two locking elements can also each be arranged on a carriage so that they can be slidably mounted or can be mounted on the first unit of the base unit and the binding holding unit from the locking position to the release position and back along an adjustment path.

As an alternative to these variants, however, there is also the possibility that the two locking elements are not mounted or can be mounted on the first unit of the base unit and the binding holding unit so that they can be displaced from the locking position to the release position and back along an adjustment path, but instead, for example, pivoted on the first unit of the Base unit and the binding holding unit are mounted movable from the locked position to the release position and back.

The two locking elements are preferably in a different position relative to one another in the locking position than in the release position. This has the advantage that the Fastening device can be constructed in a simple manner in such a way that the two locking elements can each form a positive connection with a second unit of the base unit and the binding holding unit in the locking position, wherein in the release position of the locking elements the positive connection of the two locking elements with the second of the Base unit and the bond holding unit is resolved. As a result, the releasable locking of the binding holding unit in the first position and in the second position can be achieved in a simple manner by the locking device.

In this variant, the two locking elements are advantageously mounted or can be mounted on the first unit of the base unit and the binding holding unit so that they can be displaced from the locking position into the release position and back. However, the two locking elements can also be mounted or can be mounted pivotably on the first unit of the base unit and the binding holding unit from the locking position into the release position and back.

In an alternative to these variants, however, the two locking elements are in the same position relative to one another in the locking position as in the release position.

If the two locking elements are in a different position relative to each other in the locking position than in the release position, then in a first preferred variant the two locking elements together assume a greater length in a horizontal direction, measured perpendicularly to the longitudinal axis of the base unit, in the locking position than in the release position. That is to say, a continuous stretch oriented horizontally perpendicular to the longitudinal axis of the base unit, within which stretch the two locking elements are located and which stretch has the smallest possible length for this, is preferably longer in the locking position than in the release position. This has the advantage that the binding holding unit can be locked particularly reliably in the respective first position of the binding holding unit along the longitudinal axis of the base unit relative to the base unit and in the second position of the binding holding unit along the longitudinal axis of the base unit relative to the base unit, since the two locking elements due to the longer distance in the locked position on both Ends of the stretch can each form the positive connection with a second unit of the base unit and the binding holding unit. It is irrelevant whether the two locking elements are located on a straight line oriented horizontally perpendicular to the longitudinal axis of the base unit or whether the two locking elements are offset relative to one another along the longitudinal axis of the base unit. Particularly preferably, however, the two locking elements are located in the locking position on a straight line oriented horizontally perpendicular to the longitudinal axis of the base unit. This has the advantage that the two locking elements in the locking position can each form the form-fitting connection with a second unit of the base unit and the binding holding unit, mirror-symmetrically to a mirror plane running vertically along the middle of the ski, which means that the binding holding unit can be locked in a particularly stable and reliable manner in the respective first Position of the binding holding unit along the longitudinal axis of the base unit relative to the base unit and the second position of the binding holding unit along the longitudinal axis of the base unit relative to the base unit can be achieved.

The two locking elements are preferably located further apart in the locking position than in the release position, measured perpendicular to the longitudinal axis of the base unit, in particular measured in a horizontally oriented direction perpendicular to the longitudinal axis of the base unit. However, there is also the possibility that the two locking elements, measured perpendicular to the longitudinal axis of the base unit, in particular measured in a horizontally oriented direction perpendicular to the longitudinal axis of the base unit, overlap both in the locking position and in the release position.

If the two locking elements are in a different position relative to each other in the locking position than in the release position, then in a preferred second preferred variant the two locking elements together take up a smaller length in the locking position than measured in a direction horizontally perpendicular to the longitudinal axis of the base unit in the release position. That is, a continuous stretch aligned in a direction horizontally perpendicular to the longitudinal axis of the base unit, within which stretch the two locking elements are located and which stretch has the smallest possible length for this, is preferably shorter in the locking position than in the release position. This has the advantage that the binding holding unit is more compact can be constructed. It is irrelevant whether the two locking elements are located on a straight line oriented horizontally perpendicular to the longitudinal axis of the base unit or whether the two locking elements are offset relative to one another along the longitudinal axis of the base unit.

The two locking elements are preferably located closer together in the locking position than in the release position, measured perpendicular to the longitudinal axis of the base unit, in particular measured in a horizontally oriented direction perpendicular to the longitudinal axis of the base unit. However, there is also the possibility that the two locking elements, measured perpendicular to the longitudinal axis of the base unit, in particular measured in a horizontally oriented direction perpendicular to the longitudinal axis of the base unit, overlap both in the locking position and in the release position.

Advantageously, the fastening device comprises a prestressed elastic element for prestressing the two locking elements towards the locking position. This has the advantage that the fastening device can be locked securely in the respective first position of the binding holding unit along the longitudinal axis of the base unit relative to the base unit and the second position of the binding holding unit along the longitudinal axis of the base unit relative to the base unit.

Advantageously, the prestressed resilient element is oriented parallel to the longitudinal axis of the base unit. This has the advantage that a longer elastic element can be used. In a variant of this, however, there is also the possibility that the prestressed elastic element is not aligned parallel to the longitudinal axis of the base unit. For example, the prestressed elastic element can also be aligned horizontally perpendicular to the longitudinal axis of the base unit.

Preferably, the prestressed elastic element is arranged on the first unit of the base unit and the binding holding unit. This has the advantage that the prestressed elastic element can be easily connected to the locking elements that are or can be movably mounted on the first unit of the base unit and the binding holding unit from a locking position to a release position and back Can be operatively connected to bias the two locking elements to the locked position.

Preferably, the prestressed elastic element is supported with a first end of the prestressed elastic element on the first unit of the base unit and the binding holding unit. This has the advantage that the two locking elements can be very effectively biased towards the locking position.

In a variant of this, the prestressed elastic element is not arranged on the first unit of the base unit and the binding holding unit. For example, the prestressed elastic element can be arranged on the second unit of the base unit and the binding holding unit.

As an alternative to this, however, there is also the possibility that the fastening device is designed without a prestressed elastic element for prestressing the two locking elements towards the locking position.

The fastening device preferably has a positive control, by means of which the two locking elements can be moved relative to one another in order to move the two locking elements from the locking position into the release position and back. This has the advantage that the two locking elements can be moved from the locking position to the release position and back in a very simple manner in a controlled manner.

If the fastening device comprises the prestressed elastic element for prestressing the two locking elements towards the locking position, the forced control can preferably be prestressed by the prestressed elastic element in order to prestress the two locking elements towards the locking position. If the prestressed elastic element is supported with a first end of the elastic element on the first unit of the base unit and the binding holding unit, the elastic element is preferably supported with a second end of the elastic element on the constraint control.

The positive control preferably comprises a slide that can be displaced along the longitudinal axis of the base unit in order to lock the two locking elements relative to one another move to move the two locking members from the locked position to the release position and back. This has the advantage that the two locking elements can be moved from the locking position to the release position and back in a simple manner.

The slide is preferably mounted on the first unit of the base unit and the binding holding unit so that it can be displaced relative to the first unit of the base unit and the binding holding unit. This has the advantage that the movement of the slider can be easily transferred to a movement of the two locking elements mounted on the first unit of the base unit and the binding holding unit.

The slide is preferably in operative connection with the two locking elements and can be moved by moving the first of the two locking elements and/or the second locking element when the two locking elements are moved away from their locking position by the first of the two locking elements or the second of the two Locking elements is moved.

Preferably, a first of the two locking elements has a first guide shape and a second of the two locking elements has a second guide shape, with the slide having a third guide shape and a fourth guide shape, with the first guide shape interacting with the third guide shape and the second guide shape with the fourth guide shape works together. This has the advantage that a movement of the slide can be reliably transmitted to the two locking elements.

If the fastening device comprises the prestressed elastic element for prestressing the two locking elements towards the locking position, the slide which is displaceable along the longitudinal axis of the base unit can preferably be prestressed by the prestressed elastic element in order to prestress the two locking elements towards the locking position. When the prestressed elastic element is supported with a first end of the elastic element on the first unit of the base unit and the binding holding unit, the elastic element is preferably with the second end of the elastic element on the slide and thus supported on the positive control.

In a variant of this, however, there is also the possibility that the two locking elements and the slide do not have such a first guide form, second guide form, third guide form and fourth guide form.

Advantageously, the fastening device has a blocking lever, which can be moved from an active position to a passive position and back when the two locking elements are in the locking position, wherein in the active position of the blocking lever the blocking lever prevents displacement of the slide and thus a Movement of the two locking elements away from the locked position is prevented. This has the advantage that the binding holding unit can be locked very reliably in the first position of the binding holding unit along the longitudinal axis of the base unit relative to the base unit and in the second position of the binding holding unit along the longitudinal axis of the base unit relative to the base unit.

Preferably, in the passive position of the blocking lever, the slide can be displaced or, in the passive position of the blocking lever, the displacement of the slide is no longer prevented, with the result that the two locking elements can be moved away from the locking position. This has the advantage that the fastening device can be designed to be very easy to use.

Advantageously, the blocking lever is pivotally mounted on the slide from its active position to its passive position and back so that it can be adjusted. This has the advantage that in the passive position the blocking lever can also be pivoted into a position in which it allows the slide to be easily moved. In a variant of this, however, there is also the possibility that the blocking lever is mounted on the slide so that it can be displaced from its active position into its passive position and back.

Preferably, the blocking lever has a first stop for bearing against a second stop arranged on the first unit of the base unit and the binding holding unit when the blocking lever is in the active position, in order to prevent the sliding of the slider and thus the movement of the two locking elements away from the locking position to prevent. However, the blocking lever can also be designed without such a first stop.

However, there is also the possibility that the fastening device does not have a blocking lever which can be moved from an active position to a passive position and back.

As an alternative to these variants, however, there is also the possibility that the fastening device does not have such a forced control.

In a first preferred variant, the first unit of the base unit and the binding holding unit is the base unit and the second unit of the base unit and the binding holding unit is the binding holding unit.

In a second preferred variant, the first unit of the base unit and the binding holding unit is the binding holding unit and the second unit of the base unit and the binding holding unit is the base unit.

Ways to carry out the invention

the figure 1 shows a side view of a fastening device 1 according to the invention for fastening a binding unit of a ski binding and thus a front unit 101 of a ski binding and/or a heel unit 102 of a ski binding on a ski and for adjusting a position of the binding unit of the ski binding in the longitudinal direction of the ski relative to the ski, wherein in figure 1 the mounting device 1 is shown with the front unit 101 mounted thereon.

This fastening device 1 comprises a base unit 2 for fastening the fastening device 1 to a ski, not shown here, a binding holding unit 3, to which the binding unit or the front unit 101 is attached, and a blocking lever 7 arranged on the binding holding unit 3 figure 1 the fastening device 1 is shown oriented in such a way that the blocking lever 7 is on the right in the illustration. The front unit 101 is aligned on the binding holding unit 3 and attached to the binding holding unit 3 in such a way that it is located at the front on the left in relation to the ski in the illustration.

the figure 2 shows a side view of the already in figure 1 shown fastening device 1 according to the invention, but in the present case with a heel unit fastened thereon 102 of a ski binding. The fastening device 1 is shown oriented in such a way that the blocking lever 7 is on the left in the illustration. However, the heel unit 102 is attached to the binding holding unit 3 in such a way that it is aligned on the binding holding unit 3 in such a way that it is at the front in relation to the ski in the illustration as already shown in FIG figure 1 located on the left.

In both Figures 1 and 2 the binding holding unit 3 is mounted on the base unit 2 so that it can be displaced along a longitudinal axis of the base unit 2 relative to the base unit 2 from a first position to a second position and back, in order to arrange the front unit 101 or the heel unit 102 in different positions in the longitudinal direction of the ski relative to the ski be able. As a result, a distance between the front unit 101 and the heel unit 102 can be changed in order to be able to adapt the ski binding, which comprises the front unit 101 and the heel unit 102, to ski boots of different sizes.

the figure 3 shows an exploded view of the Figures 1 and 2 shown fastening device 1 according to the invention in an oblique view. As in figure 3 can be seen, the fastening device 1 comprises a base unit 2 for fastening the fastening device 1 on the ski, not shown here, by means of fastening screws 10.1, 10.2, 10.3, 10.4. This base unit 2 is a base plate. It is formed from a piece of sheet metal and has upstanding edges running along its longitudinal axis on both sides. Upper edges of these edges are bent towards the center of the ski and each have six indentations 20.1, 20.2 along the longitudinal axis of the base unit 2.

The fastening device 1 further comprises a binding holding unit 3, to which the binding unit can be fastened, the binding holding unit 3 being storable or storable along the longitudinal axis of the base unit 2 relative to the base unit 2 from a first position to a second position and back to be displaceable on the base unit 2 . The fastening device 1 further comprises a locking device 4 for releasably locking the binding holding unit 3 in the first position of the binding holding unit 3 along the longitudinal axis of the base unit 2 relative to the base unit 2 and in the second position of the binding holding unit 3 along the longitudinal axis of the base unit 2 relative to the base unit 2. This locking device 4 has two locking elements 40.1, 40.2, which are mounted in the mounted state of the fastening device 1 on the binding holding unit 3 and thus on a first unit of the base unit 2 and the binding holding unit 3 from a locking position into a release position and back movable.

The two locking elements 40.1, 40.2 each have two protruding nubs 42.1, 42.2 on the side pointing away from the middle of the ski, which in the locking position can engage in two of the six notches 20.1, 20.2 arranged on each side of the base unit 2. As a result, the two locking elements 40.1, 40.2 in the locking position each form a positive connection with the base unit 2 and thus with a second unit of the base unit 2 and the binding holding unit 3 in order to hold the binding holding unit 3 in the respective first position of the binding holding unit 3 along the longitudinal axis of the Locking the base unit 2 relative to the base unit 2 and the second position of the binding holding unit 3 along the longitudinal axis of the base unit 2 relative to the base unit 2 . More precisely, due to the six notches 20.1, 20.2 on each side of the base unit 2 and the two knobs 42.1, 42.2 of the two locking elements 40.1, 40.2, the binding holding unit 3 can be locked in a total of five different positions along the longitudinal axis of the base unit 2 relative to the base unit 2.

In the release position of the locking elements 40.1, 40.2, the positive connection of the two locking elements 40.1, 40.2 with the second unit of the base unit 2 and the binding holding unit 3 is released, so that the binding holding unit 3 can be moved along the longitudinal axis of the base unit 2 relative to the base unit 2 from the first position in the second position and back, or so that the binding holding unit 3 can be moved back and forth along the longitudinal axis of the base unit 2 relative to the base unit 2 between the five different positions. The two locking elements 40.1, 40.2 in the mounted state of the fastening device 1 are each mounted essentially horizontally and essentially perpendicularly relative to the base unit 2 on the first unit of the base unit 2 and the binding holding unit 3 so that they can be displaced from the locked position to the release position and back along an adjustment path. As in figure 3 As can be seen, the two locking elements 40.1, 40.2 are each designed as a carriage for this purpose. As a result, the two locking elements 40.1, 40.2 act in the locking position in a direction of the longitudinal axis of the base unit 2 in a form-fitting manner with the first unit of the base unit 2 and the binding holding unit 3, thereby forming the form-fitting connection with the second unit of the base unit 2 and the binding holding unit 3 in order to hold the binding holding unit 3 in the respective first position of the Binding holding unit 3 along the longitudinal axis of the base unit 2 relative to the base unit 2 and the second position of the binding holding unit 3 along the longitudinal axis of the base unit 2 relative to the base unit 2 to lock.

The fastening device 1 also has a positive control 5, by means of which the two locking elements 40.1, 40.2 can be moved relative to one another in order to move the two locking elements 40.1, 40.2 from the locking position into the release position and back. This positive control 5 includes a slide 50 which is mounted on the binding holding unit 3 and thus on the first unit of the base unit 2 and the binding holding unit 3 so that it can be displaced relative to the first unit of the base unit 2 and the binding holding unit 3 . The slide 50 can be displaced along the longitudinal axis of the base unit 2 in order to move the two locking elements 40.1, 40.2 relative to one another in order to move the two locking elements 40.1, 40.2 from the locking position into the release position and back. For this purpose, the slide 50 is in operative connection with the two locking elements 40.1, 40.2 and can be moved by moving the first of the two locking elements 40.1 and/or the second locking element 40.2 when the two locking elements 40.1, 40.2 are moved away from their locking position by the first of the two locking elements 40.1 or the second of the two locking elements 40.2 is displaced. In order to achieve this operative connection, a first of the two locking elements 40.1 has a first guide shape 41.1, while a second of the two locking elements 40.2 has a second guide shape 41.2, with the slide 50 having a third guide shape 51.1 and a fourth guide shape 51.2, the first Management form 41.1 interacts with the third management form 51.1 and the second management form 41.2 interacts with the fourth management form 51.2. These guide forms 41.1, 41.2, 51.1, 51.2 are grooves running in a plane parallel to the ski, which are diagonal to the longitudinal axis of the base unit 2. In FIG figure 3 shown exploded view, these grooves of the first guide form 41.1 and the second guide form 41.2 are open at the top and correspondingly clearly visible. However, the third guide form 51.1 and fourth guide form 51.2 arranged in the slide 50 are located on the underside of the slide 50 and are open at the bottom and are therefore in the figure 3 not properly recognizable. In the assembled state of the fastening device 1, the grooves of the first guide form 41.1 engage in the grooves of the third guide form 51.1, while the grooves of the second guide form 41.2 engage in the grooves of the fourth guide form 51.2. Due to the diagonal alignment of the grooves, a displacement of the slider 50 in a first direction along the longitudinal axis of the base unit 2 leads to a contraction of the two locking elements 40.1, 40.2, while a displacement of the slider 50 in the opposite direction to a moving apart of the two locking elements 40.1, 40.2 leads.

As in figure 3 can further be seen, the fastening device 1 comprises a prestressed elastic element 6 for prestressing the two locking elements 40.1, 40.2 towards the locking position. In the mounted state of the fastening device 1 , this prestressed elastic element 6 is aligned parallel to the longitudinal axis of the base unit 2 and is arranged on the binding holding unit 3 and thus on the first unit of the base unit 2 and the binding holding unit 3 . When the fastening device 1 is in the assembled state, the prestressed elastic element 6 is connected to a first end of the prestressed elastic element 6 on the first unit of the base unit 2 and the binding holding unit 3 and to a second end of the prestressed elastic element opposite the first end of the elastic element 6 6 supported on slide 50. As a result, the slide 50, which can be displaced along the longitudinal axis of the base unit 2, can be pretensioned in order to pretension the two locking elements 40.1, 40.2 towards the locking position.

Next is in figure 3 to recognize that the fastening device 1 has a blocking lever 7, which is pivotably mounted about an axis 52 on the slide 50 from an active position to a passive position and back adjustable. When the two locking elements 40.1, 40.2 are in the locking position, the blocking lever 7 can be moved from an active position to a passive position and back. In the active position of the blocking lever 7, the blocking lever 7 causes the slide to be displaced 50 prevented. This prevents the two locking elements 40.1, 40.2 from moving away from the locking position. In the passive position of the blocking lever 7, on the other hand, the slider 50 can be displaced or the displacement of the slider 50 is no longer prevented, with the result that the two locking elements 40.1 40.2 can be moved away from the locking position. In order to achieve this, the blocking lever 7 has a first stop 71 for bearing against a second stop 31 arranged on the first unit of the base unit 2 and the binding holding unit 3 when the blocking lever 7 is in the active position, in order to prevent the sliding of the slide 70 and thus the To prevent movement of the two locking elements 40.1, 40.2 away from the locked position. In the passive position of the blocking lever 7, on the other hand, the first stop 71 is moved away from the second stop 31.

the Figures 4a, 4b and 4c each show an oblique view on the right of the fastening device 1 shown in the previous figures from the same perspective as in figure 3 shown exploded view and on the left an enlarged section of the area of the fastening device 1 circled in the respective oblique view shown on the right. These sections shown on the left each show two of the notches 20.1 in the base unit 2 and the two knobs 42.1 on one of the two locking elements 40.1, which can engage in these notches 20.1 in order to form the positive connection with a second unit of the base unit 2 and the binding holding unit 3 in the locking position.

In the Figure 4a the blocking lever 7 is pivoted upwards into its passive position and shown pushed together with the slide 50 in the illustration to the top left against the prestressed elastic element 6 . As a result, the two locking elements 40.1, 40.2 are moved towards one another and their nubs 42.1, 42.2 are removed from the notches 20.1, 20.2. As a result, the positive connection of the two locking elements 40.1, 40.2 with the second unit of the base unit 2 and the binding holding unit 3 is released and the two locking elements 40.1, 40.2 are in the release position. Therefore, the binding holding unit 3 can be displaced along the longitudinal axis of the base unit 2 relative to the base unit 2 from the first position to the second position and back or between the total of five positions.

In the Figure 4b the blocking lever 7 is also pivoted upwards into its passive position. However, in the Figure 4b the slide 50 is pushed away from the elastic element 6 by the prestressed elastic element 6 and is thus shown shifted downwards to the right in the illustration. As a result, the two locking elements 40.1, 40.2 are moved away from one another and their knobs 42.1, 42.2 each engage in two notches 20.1, 20.2. As a result, the two locking elements 40.1, 40.2 are in the locking position and each form a positive connection with the base unit 2 and thus a second unit of the base unit 2 and the binding holding unit 3 in order to lock the binding holding unit 3 in its position relative to the base unit 2. How thus by the Figures 4a and 4b is illustrated, the two locking elements 40.1, 40.2 are in the locking position in a different position relative to each other than in the release position. Thus, the two locking elements 40.1, 40.2 together in a horizontal direction, measured perpendicular to the longitudinal axis of the base unit 2, have a greater length in the locking position than in the release position. That is to say, a continuous stretch aligned horizontally perpendicular to the longitudinal axis of the base unit 2, within which stretch the two locking elements 40.1, 40.2 are located and which stretch has the smallest possible length for this, is longer in the locking position than in the release position.

In the Figure 4c is compared to Figure 4b only the blocking lever 7 pivoted down into its active position. As a result, the first stop 71 is supported on the second stop 31 and the slide 50 can no longer be displaced against the prestressed elastic element 6 . The two locking elements 40.1, 40.2 are thus blocked in the locking position and cannot be moved into the release position. Only when the blocking lever 7 is pivoted into the passive position can the slide 50 be displaced against the prestressed elastic element 6 and the two locking elements 40.1, 40.2 be moved into the release position.

the Figures 5a, 5b and 5c each show a top view of the fastening device 1 shown in the preceding figures, with the binding holding unit 3 in a different position along the longitudinal axis of the base unit 2 relative to the base unit 2 shown locked. The locking elements 40.1, 40.2 are each in the locking position and the blocking lever 7 is each in the active position.

The invention is not limited to the embodiment described above with reference to the figures. In a first example, the cams of the locking elements also face the middle of the ski and, in the locking position, engage in corresponding notches in the base unit in order to form the positive connection of the two locking elements with the base unit. In this case, the two locking elements together have a smaller length measured in a horizontal direction perpendicular to the longitudinal axis of the base unit in the locking position than in the release position. In a further example, the slider and the locking elements are mounted on the base unit, in which case the locking elements can engage in the locking position, for example, in corresponding notches in the binding holding unit in order to form the positive connection of the two locking elements with the binding holding unit. In this case, the first unit of the base unit and the binding-holding unit is the base unit, while the binding-holding unit is the second unit of the base unit and the binding-holding unit.

However, further variants and variations are also directly accessible to the person skilled in the art.

In summary, it can be stated that a fastening device belonging to the technical field mentioned at the outset is created which can be manufactured simply and inexpensively, which is easy to operate and allows a binding unit of a ski binding to be fastened very stably on a ski.
