Description

Technical field

[0001] The invention relates to a fastening device for attaching 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, to a SI <i und zum Einstellen einer Position der Bindungseinheit der Skibindung in Skilängsrichtung relativ zum Ski.This fastening device comprises a base unit for attaching the fastening device to the ski, a binding holding unit to which the binding unit can be attached, wherein the binding holding unit is mounted or can be mounted on the base unit in a manner that is slidable along a longitudinal axis of the base unit relative to the base unit from a first position to a second position and back, 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

[0002] Fastening devices belonging to the aforementioned technical field are known. For example, DE 10 2016 123 488 A1 of Marker Deutschland GmbH describes such a fastening device. Furthermore, WO 2008 / 017573 A2 of Vist SRL describes a fastening device for connecting a ski binding to a ski, comprising a first plate and a second plate that are substantially parallel to the SI

[0003] Such fastening devices have the disadvantage that they have very complex and sometimes very delicate elements, which can only be manufactured using elaborate processes and are therefore time-consuming and expensive, in order to ensure a stable fastening of a binding unit of a ski binding on a SI ​​

[0004] For the description of such fastening devices, a (fictitious) SI is often used as a reference system. <i verwendet, wobei angenommen wird, dass mittels der Befestigungsvorrichtung eine Bindungseinheit bzw. eine Fronteinheit und / oder eine Ferseneinheit einer Skibindung auf diesem SI<i montiert sei. Diese Gewohnheit wird im vorliegenden Text übernommen. So bedeutet der Begriff "Skilängsrichtung" entlang der Ausrichtung der Längsachse des Skis. Ähnlich bedeutet "skiparallel" für ein längliches Objekt entlang der Längsachse des Skis ausgerichtet. Für ein flächiges Objekt hingegen bedeutet der Begriff "skiparallel" parallel zur Gleitfläche des Skis ausgerichtet. Weiter ist mit dem Begriff "Skiquerrichtung" eine Richtung quer zur Skilängsrichtung gemeint, welche aber nicht genau rechtwinklig zur Längsachse des Skis orientiert sein muss. Ihre Ausrichtung kann auch etwas von einem rechten Winkel abweichen.The term "ski center", in turn, means the center of the ski when viewed in the transverse direction, while the term "ski fixed" means not movable relative to the SI. Description of the invention

[0005] ​The object of the invention is to create a fastening device belonging to the aforementioned technical field, which can be manufactured simply and cost-effectively, is easy to operate and provides a very stable fastening of a binding unit of a ski binding on a SI

[0006] ​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 are mounted or can be mounted on a first unit of the base unit and the binding holding unit so as to be movable from a locking position to a release position and back, wherein 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, wherein the two locking elements in the locking position each form a positive locking connection with a second unit of the base unit and the binding holding unit in order 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 in 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 locking 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 relative to the base unit from the first position to the second position and back, wherein the fastening device has a positive control by which the two locking elements are movable relative to each other in order to move the two locking elements from the locking position to the release position and back, wherein the fastening device includes a pre-tensioned elastic element for pre-tensioning the two locking elements towards the locking position.

[0007] According to the invention, the fastening device comprises a base unit for attaching the fastening device to the ski. Preferably, this base unit is a base plate for attaching the fastening device to the ski. Alternatively, the base unit can also be designed in a form other than that of a base plate.

[0008] 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 as to be displaceable along a longitudinal axis of the base unit relative to the base unit from a first position to a second position and back. When the fastening device is mounted on the SI

[0009] ​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 as to be movable from a locking position to a release position and back. That is, in the assembled state of the fastening device, these two locking elements are preferably 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.

[0010] According to the invention, in the locked position, the two locking elements each form a positive-locking connection with a second unit of the base unit and the binding holding unit in order 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 in the second position of the binding holding unit along the longitudinal axis of the base unit relative to the base unit, and thus to prevent a displacement 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. According to the invention, the second unit of the base unit and the binding holding unit is different from the first unit of the base unit and the binding holding unit., if the first unit of the base unit and the bond-holding unit is the base unit, then the second unit of the base unit and the bond-holding unit is preferably the bond-holding unit, whereas if the first unit of the base unit and the bond-holding unit is the bond-holding unit, then the second unit of the base unit and the bond-holding unit is preferably the base unit.

[0011] Due to the two locking elements and their positive connection with the second unit of the base unit and the binding holding unit in the locking position, a very stable attachment of a binding unit of a ski binding to a SI can be achieved in a simple way.

[0012] ​Preferably, in the locked position, the two locking elements interact positively with the first unit of the base unit and the binding retaining unit in a direction along the longitudinal axis of the base unit, thereby each forming a positive connection with the second unit of the base unit and the binding retaining unit, in order to lock the binding retaining unit in the respective first position of the binding retaining unit along the longitudinal axis of the base unit relative to the base unit and in the second position of the binding retaining unit along the longitudinal axis of the base unit relative to the base unit.Preferably, the two locking elements are positioned in the locked position relative to the first unit of the base unit and the binding unit such that movement of the two locking elements relative to the first unit of the base unit and the binding unit in any direction along the longitudinal axis of the base unit is prevented due to a positive locking connection between the two locking elements and the first unit of the base unit and the binding unit. This has the advantage that, together with the positive locking connection of the two locking elements to the second unit of the base unit and the binding unit, a very stable, releasable locking of the binding unit can be achieved in a simple manner in the first position of the binding unit along the longitudinal axis of the base unit relative to the base unit and in the second position of the binding unit along the longitudinal axis of the base unit relative to the base unit.

[0013] Alternatively, it is also possible that the two locking elements, in the locked position, do not interact positively with the first unit of the base unit and the binding unit in one direction along the longitudinal axis of the base unit. For example, the two locking elements in the locked position can be held by a frictional connection in one direction along the longitudinal axis of the base unit relative to the first unit of the base unit and the binding unit, thereby each forming a positive connection with the second unit of the base unit and the binding unit in order to lock the binding unit in the respective first position of the binding unit along the longitudinal axis of the base unit relative to the base unit and the second position of the binding unit along the longitudinal axis of the base unit relative to the base unit.

[0014] Advantageously, the two locking elements are mounted or can be mounted essentially horizontally relative to the base unit on the first unit of the base unit and the binding holding unit, allowing movement from the locked position to the released position and back. This has the advantage that the two locking elements can be easily adjusted from the locked position to the released position and back.

[0015] Furthermore, the fastening device can be designed in a simple way so that the two locking elements in the locking position interact positively with the first unit of the base unit and the binding holding unit in one direction of the longitudinal axis of the base unit, thus achieving 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 and in the second position of the binding holding unit along the longitudinal axis of the base unit relative to the base unit.

[0016] In a variant of this, it is also possible that the two locking elements are not essentially horizontally mounted or mountable relative to the base unit on the first unit of the base unit and the binding holding unit, allowing movement from the locking position to the release position and back.

[0017] Both when the two locking elements are mounted or can be mounted in a substantially horizontal position relative to the base unit on the first unit of the base unit and the binding unit, so as to be movable from the locking position to the release position and back, and when the two locking elements are mounted or can be mounted or can be mounted in a substantially non-horizontal position relative to the base unit on the first unit of the base unit and the binding unit, so as to be movable from the locking position to the release position and back, the two locking elements are advantageously mounted or can be mounted or can be mounted in a substantially perpendicular position to the longitudinal axis of the base unit relative to the base unit on the first unit of the base unit and the binding unit, so as to be movable from the locking position to the release position and back.This has the advantage that the two locking elements can be easily brought into a positive connection with a second unit of the base unit and the binding holding unit in the locking position, and that the positive connection with the second unit of the base unit and the binding holding unit can be easily released when adjusting to the release position.

[0018] In a variant of this, it is also possible that the two locking elements are not essentially perpendicular to the longitudinal axis of the base unit relative to the base unit, but are mounted or 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.

[0019] Alternatively to these variants, it is also possible that the two locking elements are neither substantially horizontally movable relative to the base unit on the first unit of the base unit and the binding holding unit from the locking position to the release position and back, nor substantially vertically 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 locking position to the release position and back.

[0020] Advantageously, the two locking elements on the first unit of the base unit and the binding unit are each slidably mounted or mountable along an adjustment path from the locked position to the released position and back. In the assembled state of the fastening device, the two locking elements are thus preferably slidably mounted along the adjustment path. For this purpose, the two locking elements are preferably each designed as a slide, which is slidably mounted on the first unit of the base unit and the binding unit. This has the advantage that the two locking elements are stably mounted or mountable in a simple manner. Alternatively, the two locking elements can each be arranged on a slide in order to be slidably mounted or mountable along an adjustment path on the first unit of the base unit and the binding unit from the locked position to the released position and back.

[0021] Alternatively to these variants, it is also possible that the two locking elements are not mounted or stored on the first unit of the base unit and the binding holding unit in a way that allows them to be moved or slid along an adjustment path from the locking position to the release position and back, but are, for example, pivotably 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.

[0022] Preferably, the two locking elements are positioned differently relative to each other in the locked position than in the released position. This has the advantage that the fastening device can be easily designed so that, in the locked position, each of the two locking elements forms a positive-locking connection with a second unit of the base unit and the binding retaining unit, whereas in the released position of the locking elements, the positive-locking connection of the two locking elements with the second unit of the base unit and the binding retaining unit is released. This allows the locking device to easily and repeatedly lock the binding retaining unit in both the first and second positions.

[0023] 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 moved from the locked position to the released position and back. Alternatively, the two locking elements can also be mounted or can be pivoted on the first unit of the base unit and the binding holding unit so that they can be moved from the locked position to the released position and back.

[0024] In an alternative to these variants, the two locking elements are in the same position relative to each other in the locking position as in the release position.

[0025] If the two locking elements are in a different position relative to each other in the locked position than in the released position, then in a first preferred embodiment, the two locking elements together have a greater length in the locked position than in the released position, measured horizontally in a direction perpendicular to the longitudinal axis of the base unit. That is, a continuous segment oriented horizontally perpendicular to the longitudinal axis of the base unit, within which the two locking elements are located and which segment has the shortest possible length, is preferably longer in the locked position than in the released position.This has the advantage that the binding retaining unit can be locked particularly reliably in both its first and second positions along the longitudinal axis of the base unit relative to the base unit. This is because, due to the longer distance between the two locking elements, they can form a positive-locking connection with a second unit of the base unit and the binding retaining unit at both ends of the locking position. It is irrelevant whether the two locking elements are located on a straight line horizontally perpendicular to the longitudinal axis of the base unit or whether they are offset from each other along the longitudinal axis of the base unit.Preferably, the two locking elements are positioned on a horizontal line perpendicular to the longitudinal axis of the base unit when in the locked position. This has the advantage that, in the locked position, the two locking elements can form a positive-locking connection with a second unit of the base unit and the binding retaining unit, mirror-symmetrical to a mirror plane running vertically along the center of the ski. This results in a particularly stable and reliable locking of the binding retaining unit in both the first position of the binding retaining unit along the longitudinal axis of the base unit relative to the base unit and the second position of the binding retaining unit along the longitudinal axis of the base unit relative to the base unit.

[0026] Preferably, the two locking elements are positioned further apart in the locked position than in the released position, measured perpendicular to the longitudinal axis of the base unit, particularly in a horizontally oriented direction. However, it is also possible that the two locking elements overlap in both the locked and released positions, measured perpendicular to the longitudinal axis of the base unit, particularly in a horizontally oriented direction.

[0027] If the two locking elements are in a different position relative to each other in the locked position than in the released position, then in a preferred second embodiment, the two locking elements together have a shorter length in the locked position than in the released position, measured horizontally perpendicular to the longitudinal axis of the base unit. That is, a continuous segment oriented horizontally perpendicular to the longitudinal axis of the base unit, within which the two locking elements are located and which segment has the shortest possible length, is preferably shorter in the locked position than in the released position. This has the advantage that the binding holding unit can be designed more compactly.It is irrelevant whether the two locking elements are located on a horizontal line perpendicular to the longitudinal axis of the base unit or whether the two locking elements are offset from each other along the longitudinal axis of the base unit.

[0028] Preferably, the two locking elements are located closer together in the locked position than in the released position, measured perpendicular to the longitudinal axis of the base unit, particularly in a horizontally oriented direction. However, it is also possible that the two locking elements overlap in both the locked and released positions, measured perpendicular to the longitudinal axis of the base unit, particularly in a horizontally oriented direction.

[0029] According to the invention, the fastening device comprises a pre-tensioned elastic element for pre-tensioning the two locking elements towards the locking position. This has the advantage that the fastening device can be securely locked 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.

[0030] Advantageously, the prestressed elastic element is aligned parallel to the longitudinal axis of the base unit. This allows for the use of a longer elastic element. However, a variation of this allows the prestressed elastic element to be aligned differently. For example, it can be horizontally perpendicular to the longitudinal axis of the base unit.

[0031] 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 brought into operative contact with the locking elements, which are mounted or can be moved from a locking position to a release position and back on the first unit of the base unit and the binding holding unit, in order to prestress the two locking elements towards the locking position.

[0032] Preferably, the prestressed elastic element is supported at a first end on the first unit of the base unit and the binding retaining unit. This has the advantage that the two locking elements can be prestressed very effectively towards the locking position.

[0033] In one variation, the prestressed elastic element is not located on the first unit of the base unit and the bonding unit. For example, the prestressed elastic element can be located on the second unit of the base unit and the bonding unit.

[0034] According to the invention, the fastening device has a positive control mechanism by which the two locking elements are movable relative to each other in order to move the two locking elements from the locked position to the released position and back. This has the advantage that the two locking elements can be moved very easily and in a controlled manner from the locked position to the released position and back.

[0035] If the fastening device includes the pre-tensioned elastic element for pre-tensioning the two locking elements towards the locking position, then the positive control can preferably be pre-tensioned by the pre-tensioned elastic element to pre-tension the two locking elements towards the locking position. If the pre-tensioned elastic element is supported at a first end of the elastic element on the first unit of the base unit and the binding holding unit, then the elastic element is preferably supported at a second end of the elastic element on the positive control.

[0036] Preferably, the positive control mechanism comprises a slider that is movable along the longitudinal axis of the base unit to move the two locking elements relative to each other, in order to move the two locking elements from the locked position to the released position and back. This has the advantage that the two locking elements can be moved from the locked position to the released position and back in a simple manner.

[0037] Preferably, the slide is slidably mounted on the first unit of the base unit and the binding holding unit relative to the first unit of the base unit and the binding holding unit. This has the advantage that the movement of the slide 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.

[0038] Preferably, the slide is operatively connected to the two locking elements and can be moved by shifting 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 shifting the first of the two locking elements or the second of the two locking elements.

[0039] Preferably, a first of the two locking elements has a first guide form and a second of the two locking elements has a second guide form, wherein the slide has a third guide form and a fourth guide form, the first guide form interacting with the third guide form and the second guide form interacting with the fourth guide form. This has the advantage that a reliable transmission of a movement of the slide to the two locking elements can be achieved.

[0040] If the fastening device includes the pre-tensioned elastic element for pre-tensioning the two locking elements towards the locking position, then the slide, which is displaceable along the longitudinal axis of the base unit, can preferably be pre-tensioned by the pre-tensioned elastic element to pre-tension the two locking elements towards the locking position. If the pre-tensioned elastic element is supported at one end on the first unit of the base unit and the binding holding unit, then the elastic element is preferably supported at the other end on the slide and thus on the positive control mechanism.

[0041] In a variant, however, it is also possible that the two locking elements and the slider do not have such a first guide form, second guide form, third guide form and fourth guide form.

[0042] Advantageously, the fastening device has a block. <ierhebel auf, welcher von einer aktiven Stellung in eine passive Stellung und zurück verstellbar ist, wenn sich die zwei Arretierelemente in der Arretierstellung befinden, wobei in der aktiven Stellung des Blocl<ierhebels durch den Blocl<ierhebel ein Verschieben des Schiebers verhindert und damit ein Bewegen der zwei Arretierelemente von der Arretierstellung weg verhindert wird. Dies hat den Vorteil, dass die Bindungshalteeinheit sehr zuverlässig in der jeweiligen der ersten Position der Bindungshalteeinheit entlang der Längsachse der Basiseinheit relativ zur Basiseinheit und der zweiten Position der Bindungshalteeinheit entlang der Längsachse der Basiseinheit relativ zur Basiseinheit arretiert werden kann.

[0043] Preferably, the block is in the passive position. <ierhebels der Schieber verschiebbar bzw. ist in der passiven Stellung des Blocl<ierhebels das Verschieben des Schiebers nicht mehr verhindert, womit die zwei Arretierelemente von der Arretierstellung weg bewegt werden können. Dies hat den Vorteil, dass die Befestigungsvorrichtung sehr einfach bedienbar ausgestaltet werden kann.

[0044] Advantageously, the block <ierhebel schwenkbar am Schieber von seiner aktiven Stellung in seine passive Stellung und zurück verstellbar gelagert. Dies hat den Vorteil, dass der Blocl<ierhebel in der passiven Stellung zudem in eine Stellung geschwenkt sein kann, in welcher er ein einfaches Verschieben des Schiebers ermöglicht. In einer Variante dazu besteht aber auch die Möglichkeit, dass der Blocl<ierhebel verschiebbar am Schieber von seiner aktiven Stellung in seine passive Stellung und zurück verstellbar gelagert ist.

[0045] Preferably the block <ierhebel einen ersten Anschlag zum Abstützten an einem an der ersten Einheit der Basiseinheit und der Bindungshalteeinheit angeordneten zweiten Anschlag in der aktiven Stellung des Blocl<ierhebels auf, um das Verschieben des Schiebers und damit das Bewegen der zwei Arretierelemente von der Arretierstellung weg zu verhindern. Der Blocl<ierhebel kann aber auch ohne solchen ersten Anschlag ausgebildet werden.

[0046] However, it is also possible that the fastening device does not have a block. <ierhebel aufweist, welcher von einer aktiven Stellung in eine passive Stellung und zurück verstellbar ist.

[0047] In a first preferred variant, the first unit of the base unit and the bond-holding unit is the base unit, and the second unit of the base unit and the bond-holding unit is the bond-holding unit.

[0048] In a second preferred variant, the first unit of the base unit and the bond-holding unit is the bond-holding unit, and the second unit of the base unit and the bond-holding unit is the base unit.

[0049] Further advantageous embodiments and combinations of features of the invention can be derived from the following detailed description and the entirety of the patent claims. Brief description of the drawings

[0050] The drawings used to illustrate the exemplary embodiment show: Fig. 1 a side view of a fastening device according to the invention with a front unit of a ski binding attached thereto, Fig. 2 a side view of the fastening device according to the invention with a heel unit of a ski binding attached thereto, Fig. 3 an exploded view of the fastening device according to the invention in an oblique view, Fig. 4a, b, c each on the right an oblique view of the fastening device shown in the preceding figures from the same perspective as in Figure 3 The exploded view shown and, on the left, an enlarged section of the oblique view shown on the right. <reisten Bereichs der Befestigungsvorrichtung, und Fig. 5a, b, cje eine Aufsicht auf die in den vorgehenden Figuren gezeigten Befestigungsvorrichtung, wobei die Bindungshalteeinheit jeweils in einer anderen Position entlang der Längsachse der Basiseinheit relativ zur Basiseinheit arretiert gezeigt ist.

[0051] Basically, identical parts in the figures are marked with the same reference symbols. Ways to implement the invention

[0052] The Figure 1 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 SI Figure 1 The fastening device 1 with the front unit 101 attached to it is shown.

[0053] This fastening device 1 comprises a base unit 2 for attaching the fastening device 1 to a ski (not shown here), a binding holding unit 3 to which the binding unit or front unit 101 is attached, and a block arranged on the binding holding unit 3. <ierhebel 7. In der Figure 1 ​The fastening device 1 is shown oriented such that the locking lever 7 is located on the right in the illustration. The front unit 101 is attached to the binding holding unit 3 in such a way that it is positioned at the front with respect to the SI.

[0054] The Figure 2 shows a side view of the already in Figure 1 The fastening device 1 shown according to the invention, but in this case with a heel unit 102 of a ski binding attached to it. The fastening device 1 is shown oriented such that the block <ierhebel 7 in der Darstellung links befindet. Dabei ist jedoch die Ferseneinheit 102 derart auf der Bindungshalteeinheit 3 ausgerichtet an der Bindungshalteeinheit 3 befestigt, dass sie sich vorne in Bezug auf den SI<i in der Darstellung wie bereits in Figure 1 is on the left.

[0055] In the two Figures 1 and 2 ​The binding holding unit 3 is mounted on the base unit 2 in a way that allows it to be moved 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 position the front unit 101 or the heel unit 102 in different positions in the longitudinal direction of the ski relative to the SI.

[0056] The Figure 3 shows an exploded view of the components in the Figures 1 and 2 The fastening device 1 according to the invention is shown in an oblique view. As in Figure 3 ​As can be seen, the fastening device 1 comprises a base unit 2 for attaching the fastening device 1 to the SI (not shown here).

[0057] ​The fastening device 1 further comprises a binding holding unit 3 to which the binding unit can be attached, wherein the binding holding unit 3 can be slidably mounted on the base unit 2 from a first position to a second position and back along the longitudinal axis of the base unit 2 relative to 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 in the assembled state of the fastening device 1 are mounted on the binding holding unit 3 and thus on a first unit of the base unit 2 and the binding holding unit 3 are movable from a locking position to a release position and back.

[0058] The two locking elements 40.1, 40.2 each have two raised studs 42.1, 42.2 on their upper side, on the side facing away from the center of the ski. In the locking position, these studs can engage in two of the six notches 20.1, 20.2 arranged on each side of the base unit 2. Thus, in the locking position, the two locking elements 40.1, 40.2 each form a positive connection with the base unit 2 and therefore with a second unit of the base unit 2 and the binding retaining unit 3, in order to lock the binding retaining unit 3 in the respective first position of the binding retaining 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 retaining unit 3 along the longitudinal axis of the base unit 2 relative to the base unit 2. More precisely, due to the six indentations 20.1, 20.2 on each side of the base unit 2 and the two studs 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.

[0059] In the release position of the locking elements 40.1, 40.2, the positive locking 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 to 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. In the assembled state of the fastening device 1, the two locking elements 40.1, 40.2 are each mounted essentially horizontally and essentially vertically relative to the base unit 2 on the first unit of the base unit 2 and the binding holding unit 3, allowing them to be moved from the locking position to the release position and back along an adjustment path. As described in Figure 3As can be seen, the two locking elements 40.1, 40.2 are each designed as a slide. In the locked position, the two locking elements 40.1, 40.2 interact positively with the first unit of the base unit 2 and the binding holding unit 3 in one direction along the longitudinal axis of the base unit 2, and each form a positive connection with the second unit of the base unit 2 and the binding holding unit 3, in order to lock the binding holding unit 3 in the respective first position along the longitudinal axis of the base unit 2 relative to the base unit 2 and in the second position along the longitudinal axis of the base unit 2 relative to the base unit 2.

[0060] The fastening device 1 further comprises a positive control mechanism 5 by which the two locking elements 40.1, 40.2 are movable relative to each other in order to move the two locking elements 40.1, 40.2 from the locked position to the released position and back. This positive control mechanism 5 includes a slide 50, which is slidably mounted on the binding holding unit 3 and thus on the first unit of the base unit 2 and the binding holding unit 3 relative to the first unit of the base unit 2 and the binding holding unit 3. The slide 50 is slidable along the longitudinal axis of the base unit 2 in order to move the two locking elements 40.1, 40.2 relative to each other in order to move the two locking elements 40.1, 40.2 from the locked position to the released position and back. For this purpose, the slide 50 is operatively connected to the two locking elements 40.1, 40.2 and can be moved by shifting the first of the two locking elements 40.The first and / or second locking element 40.2 is movable when the two locking elements 40.1, 40.2 are moved away from their locking position by displacing the first of the two locking elements 40.1 or the second of the two locking elements 40.2. To achieve this operative connection, a first of the two locking elements 40.1 has a first guide form 41.1, while a second of the two locking elements 40.2 has a second guide form 41.2, wherein the slide 50 has a third guide form 51.1 and a fourth guide form 51.2, wherein the first guide form 41.1 interacts with the third guide form 51.1 and the second guide form 41.2 interacts with the fourth guide form 51.2. These leadership styles 41.1, 41.2, 51.1, 51.2 are in a sl <iparallelen Ebene verlaufende Rillen, welche diagonal zur Längsachse der Basiseinheit 2. In der in . Figure 3In the exploded view shown, the grooves of the first guide form 41.1 and the second guide form 41.2 are open at the top and therefore clearly visible. However, the third guide form 51.1 and the fourth guide form 51.2, located in the slide 50, are on the underside of the slide 50 and are open at the bottom, and are thus not visible in the Figure 3It is not clearly visible. 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 orientation of the grooves, moving the slider 50 in a first direction along the longitudinal axis of the base unit 2 causes the two locking elements 40.1, 40.2 to move together, while moving the slider 50 in the opposite direction causes the two locking elements 40.1, 40.2 to move apart.

[0061] As in Figure 3As can be further seen, the fastening device 1 comprises a pre-tensioned elastic element 6 for pre-tensioning the two locking elements 40.1, 40.2 towards the locking position. In the assembled state of the fastening device 1, this pre-tensioned 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. In the assembled state of the fastening device 1, the pre-tensioned elastic element 6 is supported at one end on the first unit of the base unit 2 and the binding holding unit 3, and at the other end opposite the first end of the pre-tensioned elastic element 6 on the slide 50. This allows the slide 50, which is movable along the longitudinal axis of the base unit 2, to be pre-tensioned to engage the two locking elements 40.1, 40.2.2. To pre-tension towards the locking position.

[0062] Furthermore, in Figure 3to recognize that the fastening device 1 is a block <ierhebel 7 aufweist, welcher um eine Achse 52 schwenkbar am Schieber 50 von einer aktiven Stellung in eine passive Stellung und zurück verstellbar gelagert ist. Wenn sich die zwei Arretierelemente 40.1, 40.2 in der Arretierstellung befinden, so ist der Blocl<ierhebel 7 von einer aktiven Stellung in eine passive Stellung und zurück verstellbar. In der aktiven Stellung des Blocl<ierhebels 7 ist durch den Blocl<ierhebel 7 ein Verschieben des Schiebers 50 verhindert. Damit wird ein Bewegen der zwei Arretierelemente 40.1, 40.2 von der Arretierstellung weg verhindert. In der passiven Stellung des Blocl<ierhebels 7 hingegen ist der Schieber 50 verschiebbar bzw. ist das Verschieben des Schiebers 50 nicht mehr verhindert, womit die zwei Arretierelemente 40.1 40.2 von der Arretierstellung weg bewegt werden können.To achieve this, the block points out <ierhebel 7 einen ersten Anschlag 71 zum Abstützten an einem an der ersten Einheit der Basiseinheit 2 und der Bindungshalteeinheit 3 angeordneten zweiten Anschlag 31 in der aktiven Stellung des Blocl<ierhebels 7 auf, um das Verschieben des Schiebers 70 und damit das Bewegen der zwei Arretierelemente 40.1, 40.2 von der Arretierstellung weg zu verhindern. In der passiven Stellung des Blocl<ierhebels 7 hingegen ist der erste Anschlag 71 vom zweiten Anschlag 31 wegbewegt.

[0063] The Figures 4a, 4b and 4c Each of the figures on the right shows an oblique view of the fastening device 1 shown in the preceding figures, from the same perspective as in Figure 3The exploded view shown and, on the left, an enlarged section of the oblique view shown on the right. <reisten Bereichs der Befestigungsvorrichtung 1. In diesen jeweils links abgebildeten Ausschnitten sind jeweils zwei der Einkerbungen 20.1 in der Basiseinheit 2 sowie die zwei Noppen 42.1 am einen der zwei Arretierelemente 40.1 gezeigt, welche in diese Einkerbungen 20.1 eingreifen können, um in der Arretierstellung die formschlüssige Verbindung mit einer zweiten Einheit der Basiseinheit 2 und der Bindungshalteeinheit 3 zu bilden.

[0064] In the Figure 4ais the block <ierhebel 7 nach oben in seine passive Stellung geschwenkt und zusammen mit dem Schieber 50 in der Darstellung nach links oben gegen das vorgespannte elastische Elemente 6 geschoben gezeigt. Dadurch sind die zwei Arretierelemente 40.1, 40.2 zueinander hin bewegt und ihre Noppen 42.1, 42.2 sind aus den Einkerbungen 20.1, 20.2 entfernt. Dadurch ist die formschlüssige Verbindung der zwei Arretierelemente 40.1, 40.2 mit der zweiten Einheit der Basiseinheit 2 und der Bindungshalteeinheit 3 aufgelöst und die zwei Arretierelemente 40.1, 40.2 befinden sich in der Freigabestellung. Daher kann die Bindungshalteeinheit 3 entlang der Längsachse der Basiseinheit 2 relativ zur Basiseinheit 2 von der ersten Position in die zweite Position und zurück bzw. zwischen den insgesamt fünf Positionen verschoben werden.

[0065] In the Figure 4b is the block <ierhebel 7 ebenfalls nach oben in seine passive Stellung geschwenkt. Allerdings ist in der Figure 4bThe slider 50 is pushed away from the elastic element 6 by the pre-tensioned elastic element 6 and is thus shown shifted downwards and to the right in the illustration. This moves the two locking elements 40.1, 40.2 away from each other, and their studs 42.1, 42.2 engage in two notches 20.1, 20.2 each. 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 with a second unit of the base unit 2 and the binding retaining unit 3, in order to lock the binding retaining unit 3 in its position relative to the base unit 2. Thus, as shown by the Figures 4a and 4bAs illustrated, the two locking elements 40.1, 40.2 are in a different position relative to each other in the locked position than in the released position. Specifically, the two locking elements 40.1, 40.2 together have a greater length in the locked position than in the released position when measured horizontally perpendicular to the longitudinal axis of the base unit 2. That is, a continuous segment oriented horizontally perpendicular to the longitudinal axis of the base unit 2, within which the two locking elements 40.1, 40.2 are located and which segment has the shortest possible length, is longer in the locked position than in the released position.

[0066] In the Figure 4c is compared to Figure 4bOnly the locking lever 7 pivots downwards into its active position. This causes the first stop 71 to rest against the second stop 31, and the slide 50 can no longer be moved against the pre-tensioned elastic element 6. Thus, the two locking elements 40.1, 40.2 are locked in the locking position and cannot be moved into the release position. Only when the block <ierhebel 7 in die passive Stellung geschwenkt wird, können der Schieber 50 gegen das vorgespannte elastische Element 6 verschoben und die zwei Arretierelemente 40.1, 40.2 in die Freigabestellung verstellt werden.

[0067] The Figures 5a, 5b and 5cEach figure shows a top view of the fastening device 1 shown in the preceding figures, with the binding holding unit 3 shown locked in a different position along the longitudinal axis of the base unit 2 relative to the base unit 2. The locking elements 40.1, 40.2 are each in the locked position and the block <ierhebel 7 befindet sich jeweils in der aktiven Stellung.

[0068] 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 center of the ski and, in the locked position, engage in corresponding notches in the base unit to form a positive-locking connection between the two locking elements and the base unit. In this case, the two locking elements together have a shorter length in the locked position than in the released position, measured horizontally perpendicular to the longitudinal axis of the base unit. In a further example, the slider and the locking elements are mounted on the base unit, and in this case, the locking elements can, for example, engage in corresponding notches in the binding retaining unit in the locked position to form a positive-locking connection between the two locking elements and the binding retaining unit.In this case, the first unit of the base unit and the bond-holding unit is the base unit, while the bond-holding unit is the second unit of the base unit and the bond-holding unit.

[0069] However, further variants and variations are also readily available to the expert.

[0070] In summary, it can be stated that a fastening device belonging to the aforementioned technical field is being created, which can be manufactured simply and cost-effectively, which is easy to operate and provides a very stable fastening of a binding unit of a ski binding on a SI.
