Description

The invention relates to a storage device for a ski binding, in particular a cross-country binding, which is slidably mounted on a binding plate, comprising a connecting element which can be connected to the ski binding in such a way that the connecting element and the ski binding are essentially immovable relative to one another in the direction of a longitudinal extension of the ski binding and which extends forwards from the ski binding, a fastening element which is intended to be immovably fastened to a ski carrying the ski binding in front of a front end of the ski binding, a locking device with a locking position, wherein in the locking position the connecting element and the fastening element are essentially immovably connected to one another, wherein the locking device has an open position in which the connecting element is freely displaceable relative to the fastening element and the connecting element can be positioned in at least two spaced-apart, defined functional positions in which the locking device can be transferred into the locking position, wherein the locking device has at least one slidably mounted locking element which in the locking position is accommodated in a recess in the connecting element.

Cross-country skiing involves a combination of a pushing-off and a sliding movement. Accordingly, cross-country skis usually have two different running surface sections. In the front and rear sections there are sliding zones, while in the middle section there is a climbing zone, which is used in particular during the pushing-off movement. The sliding zones are therefore designed to be as smooth as possible for good sliding properties, whereas in the climbing zone there is usually a structured or friction-increasing surface or a grip-improving wax or the like. During the pushing-off phase, an attempt is made to bring the climbing zone into contact with the snow over as much of its surface as possible, so that a forward movement is initiated. During the sliding phase, the weight of the skier is transferred to the snow primarily via the front and rear sliding zones. A good transition between the pushing-off and the climbing zone is essential for rapid progress. and gliding phases are required. Depending on personal preferences and snow and terrain conditions, it may be useful to position the ski binding a little further towards the tip of the ski or a little further back towards the tail of the ski to achieve the best possible transition between the push-off and gliding phases. If the ski binding is moved further forward during classic cross-country skiing, the push-off is usually improved, whereas if the ski binding is moved a little further back, the gliding properties are usually improved.

A large number of ski bindings or storage devices are known in which the position of the ski binding on the ski can be changed in a simple manner via a sliding bearing on a slide rail. The ski binding usually has a locking device in an area of the contact surface, i.e. between the front and rear ends of the ski binding, which, when locked, positions the ski binding firmly or immovably on the ski and, in an unlocked position, allows the ski binding to be moved on the ski. With such ski bindings or storage devices, the ski binding can therefore only be moved forwards or backwards when the boot is not currently in the ski binding, since otherwise the boot in the ski binding does not allow access to the locking device. With these known ski bindings or fastening devices, the user must therefore interrupt cross-country skiing and release the boot from the binding in order to change the binding position on the ski. This is time-consuming and not very comfortable, especially if you want to change the binding position on the ski several times during a ski run, e.g. due to changing snow conditions.

From the WO 2018/143815 A1 A bearing device for a ski binding of the type mentioned at the beginning is already known, whereby the displacement is preferably not carried out by manually operating an actuator, but is achieved with the help of an electrically driven motor. However, such a structure is technically complex, prone to errors and in particular has the disadvantage that an energy storage device for driving the motor has to be regularly charged. In the embodiments, which provide for manual movement, a movable handle is provided with which the ski binding can be moved. This means that the user's foot is moved via manual operation, which is laborious and impractical.

From the WO 2012/045723 A1 a storage device for a ski binding according to the preamble of claim 1 is known, with which the position on the ski can be changed while a ski boot is held in the ski binding. In order to achieve adjustability of the binding position while the ski boot is held in the ski binding, a movable actuator is provided. When the actuator is activated, the position of the binding is adjusted. In one embodiment, a gear is provided as the actuator, wherein rotation of the gear causes the teeth to interact with the notches or grooves in a fastening element, so that the binding moves forwards or backwards on the ski depending on the direction of rotation of the gear. A particular disadvantage of this solution is that the binding must be released from its fixed position by hand and the hand must remain on the actuator while it is being operated, e.g. the gear must be turned to change the position of the ski binding on the ski. In addition, the user's foot must be moved using manual operation; this is laborious and time-consuming.

From the CH 177960 A Another storage device for a ski binding is known, in which the ski binding is mounted so that it can move freely in an open position of the locking device. To fix the position of the ski binding, a clamping device with a cam lever is provided, via which a slide can be fixed in any intermediate position. However, a predefined position cannot be set with such a clamping device and there is also the risk that the slide will accidentally come loose from the clamped position.

From the FR 2742345 A1 A ski binding is known which is arranged directly on the surface of a ski and whose position on the ski is adjustable. In one embodiment A front connecting element is provided which has two rows of teeth on its upper side. With the help of a cam lever, a tooth plate can be pressed onto the rows of teeth so that the position of the connecting element and thus that of the ski binding is fixed directly to the ski.

It is therefore the object of the present invention to alleviate or eliminate one or more disadvantages of the prior art. In particular, it is the object of the invention to create a storage device in which the ski binding only has to be released by hand from a locked position and the longitudinal displacement can take place in another way, i.e. not necessarily by hand.

This object is achieved by the storage device according to claim 1. According to the invention, it is particularly provided that the locking device has an actuating element that can be activated via a pushing or pressing movement for transferring the locking element between a blocking position and a release position, and the actuating element positions the locking element in the blocking position in a non-activated state.

The functional positions are spaced apart from one another in the longitudinal direction of the ski binding or the longitudinal direction of the ski, so that by moving the connecting element, a ski binding connected to the connecting element, which is slidably mounted on a binding plate, is moved forwards, i.e. towards the tip of the ski, or backwards, i.e. towards the end of the ski. In order to move the connecting element and thus the ski binding, it is advantageously not absolutely necessary to permanently operate a locking device or to move the ski binding by hand, but due to the freely movable mounting of the connecting element and a ski binding mounted on a binding plate, the ski binding together with the connecting element can be moved forwards or backwards by simply moving the user's foot. Thus, a shift in the position of a on a ski binding arranged on a ski. Cross-country bindings, such as those used with the storage device according to the invention, usually have a receptacle for a pivot axis of a boot that runs transversely to the longitudinal direction of the ski binding, whereby when the ski binding is closed, the pivot axis - pivotable about its own axis - is accommodated in the receptacle, so that sufficient force for a displacement of the ski binding in the direction of the tip or end of the ski can be easily transmitted via this connection. By forming a front connecting element, which in any case also has a section that extends forwards away from the ski binding, i.e. in the direction of the tip of the ski, and is thus freely accessible during use or is not arranged exclusively below the boot accommodated in the binding, the position of the ski can thus be easily changed during use. The user only has to unlock the locking element, move the binding forwards or backwards, preferably by applying force via the foot, whereby the locking element is locked manually or at most independently in the further functional position. The storage device according to the invention is thus characterized by a quick and simple adjustment of the binding position and a high level of user-friendliness. For a high level of user comfort, the actuating element positions the locking element in the locking position in a non-activated state. The actuating element is activated by a pushing or pressing movement; in this activated state, the locking element is transferred from the locking position to the release position and the locking device is thus in the open position, in which the connecting element can be freely moved relative to the fastening element. However, as soon as the user no longer applies any pressure to the actuating element, it is preferably transferred back to the non-activated position, e.g. via a spring force, in which the locking element or the locking pins strive to be received in a recess in the connecting element. If the connecting element is therefore moved to the further functional position, the locking element or the locking pins snap into place. preferably automatically into a recess or recesses which correspond to this functional position.

In order to guide the connecting element reliably in the longitudinal direction of the ski or binding when changing the binding position and thus to facilitate the adjustment movement, it is advantageous if a linear guide is provided between the connecting element and the fastening element. With regard to a structurally simple design, which also allows existing bindings to be easily retrofitted with a storage device according to the invention, it is advantageous if the connecting element has a first linear guide, in particular in the form of essentially C-shaped side sections that engage around laterally projecting guide rails of the fastening element.

Furthermore, for easy operation when transferring between the locking and open positions of the locking device, it is advantageous if the locking device has two locking pins, which are each accommodated in a recess in the connecting element in the locking position. Such a locking element or locking pins can be easily released from the locking position by pushing or pressing. In addition, such a locking element or locking pins can also be easily held in the locking position via a spring element or spring elements, so that the user only has to briefly release the locking element or locking pins from the locking position to unlock before the connecting element is moved from the set functional position.

A simple and reliable construction for transferring the locking element between a blocking and a release position is achieved when the locking element, in particular two locking pins, are mounted in a guide rail which is connected to the actuating element. The guide rail can in particular have two arcuate sections, each of which is provided for receiving a guide pin of a locking pin. If the If the guide pins are arranged in an outer vertex of the curved sections, the locking pins are thus displaced outwards and strive to be accommodated in a recess in the connecting element. If, however, the guide rail is displaced, the guide pins are accommodated in an inner front or rear end section of the respective curved sections of the guide rail. The locking pins and thus also their outer ends are therefore not displaced inwards, so that the locking pins do not engage with the recesses in the connecting element corresponding to a functional position, whereby the locking element is freely displaceable relative to the fastening element.

In order to prevent snow or the like from getting to the fastening element or in particular to the locking element, it is advantageous if a cover is attached to the fastening element, on which the actuating element is accommodated, in particular is mounted so that it can move. It is advantageous here if the cover is pushed onto the fastening element, as this makes it easy to create a connection between the fastening element and the cover without separate fixing elements. Alternatively, the fastening element and a cover or housing can also be formed as one piece.

For reliable fixing of the cover when pushed onto the fastening element without separate fixing elements, it is advantageous if the cover has a front edge which, when pushed onto the fastening element, is received in a locking recess in the fastening element. Accordingly, the cover can be easily pushed onto the fastening element from the front, i.e. when the ski binding and the storage device are mounted, away from the tip of the ski, until a front edge of the cover snaps into place behind a front section of the fastening element which forms a locking recess. In order to simplify the elastic deformation of the cover during the sliding-on process, the cover can have a material weakening, in particular a groove on the bottom running transversely to the sliding-on direction. which promotes an elastic pivoting up of a front end section of the cover.

In order to reliably connect the cover to the fastening element, it is advantageous if laterally projecting guide rails are provided in a rear section facing the ski binding, which are at least partially accommodated in a second linear guide of the connecting element, preferably in guide grooves. The cover is thus preferably held in a front area by a linear guide of the fastening element and in a rear area by a linear guide of the connecting element. An unintentional detachment of the cover from the fastening element is therefore not possible.

The invention further comprises a ski binding, preferably a cross-country binding, with a binding element that is slidably mounted on a slide rail provided for arrangement on a ski, wherein the ski binding is connected to a storage device according to the invention in that the connecting element is connected to the binding element of the ski binding. Ski bindings known per se, in particular cross-country bindings, which are slidably mounted by a slide rail, can therefore be easily retrofitted with the storage device according to the invention in order to be able to change the position of the ski binding on the ski or on the slide rail in a quick and easy manner without having to get out of the ski binding with the boot accommodated in it. If a user therefore comes to a cross-country ski trail section in which the snow conditions have changed, he can simply stop for a moment, reach down to the storage device and, preferably by means of an interaction of hand and foot, move the ski binding quickly and easily. Alternatively, the ski binding itself can already be equipped with the connecting element of the storage device, so that the position of the ski binding on the slide rail or the ski can be adjusted in a user-friendly and simple manner when the ski binding is first manufactured.

In order to simplify the subsequent fitting of a ski binding with the storage device according to the invention, it is It is advantageous if the binding element and the connecting element have cooperating connection elements, preferably cooperating projections and receptacles. In this case, for example, two holes or recesses can be provided, preferably in a front end section of a binding element, into which corresponding projections, preferably arranged on the top side of the connecting element, are received in a locking or positive-locking manner. The two elements therefore preferably only need to be plugged together in order to create a functional connection between the ski binding and the storage device.

If it is already clear during manufacture of the ski binding that adjustment of the ski binding via the storage device according to the invention is desired, it is advantageous if the connecting element and at least one front section of the binding element are formed integrally with one another. When mounting the binding on a ski, the connecting element formed integrally with the binding element can thus be connected to a fastening element that is also attached to the ski, so that the ski binding can be easily adjusted in its position on a slide rail.

Alternatively, the connecting element can also have a fastening section that is slidably mounted in the slide rail, preferably with a perforated strip at the end, with which a detachable holding element of the binding element interacts. In this case, a double adjustment of the binding position is possible. In addition, the position of the binding relative to the connecting element can be adjusted via the fastening section. If a quick, uncomplicated adjustment of the position of the binding is desired while a boot is in the binding, a type of quick adjustment of the ski binding can be carried out via the storage device according to the invention without the user having to get out of the binding.

The invention also relates to a ski with a storage device according to the invention, wherein the fastening element is attached, in particular glued, to the ski in front of the front end of the ski binding, as seen in the direction of a ski tip. the adhesive attachment of the fastening element to the ski, the ski is advantageously not weakened by fixing elements that penetrate into the interior of the ski. The position of the ski binding, which is slidably mounted on a slide rail, can thus be easily adjusted using the storage device according to the invention.

In the Fig. 1 to 6 a first embodiment of a storage device 1 according to the invention or a cross-country ski binding 2 with the storage device 1 according to the invention on a ski 3 is shown.

Here, a cross-country binding 2 is attached via a slide rail or binding plate 4 (cf. Fig. 3 , 4a ) is slidably mounted on the ski 3. The cross-country binding 2 has a binding element 5 which is provided for receiving a ski boot (not shown). For pivotable mounting of the ski boot on the binding element 5, a receptacle 6 is provided in which a pivot axis of the ski boot can be received. A pivot axis arranged in the receptacle 6 is reliably held on the binding 2 in a closed position of a hook-shaped closure element 6a, wherein in a downwardly pivoted state of the ski boot, the ski boot essentially rests on a contact surface 5a in the front area. To accommodate a heel section of the boot, a heel element 8 is connected to the binding element 5 via a plug connection, which is slidably mounted on a rear slide rail 4a and is thus intended for joint sliding displacement with the (front) binding element 5. The closure element 6a can be transferred between an open and a closed position via a binding actuating element 7.

In order to be able to move the position of the binding on the ski 3 forwards in the direction of the (not shown) ski tip, i.e. in the direction of arrow 9, or backwards in the direction of the (not shown) ski end, i.e. in the direction of arrow 9', when the ski boot is received in the binding 2, the storage device 1 is provided in front of the (front) binding element 5; this allows the ski binding 2 to be fastened in different positions on the ski 3.

The storage device 1 has a plate-shaped fastening element 10, i.e. a fastening plate, which is firmly arranged on the ski 3. The fastening plate 10 is glued to the ski in the direction 9 in front of the front end of the ski binding 2 or the binding element 5. Due to the adhesive fastening of the fastening element 10 to the ski 3, the ski 3 is not weakened by screws or the like penetrating into the interior of the ski 3.

As particularly in the Fig. 2 to 6 shown in detail, a connecting element 11 can be locked in different positions, in the embodiment shown in two different positions, in relation to the fastening plate 10. Since the connecting element 11 is firmly connected to the binding element 5 and the two elements are immovable in the direction of displacement, ie in the longitudinal direction 12 of the ski binding or the ski 3, the position of the connecting element 11 also determines the position of the ski binding 2 on the ski 3. In order to reliably guide the connecting element 11 in the longitudinal direction 12 of the ski or binding when changing the binding position and thus to facilitate the adjustment movement, a Linear guide is provided between the connecting element 11 and the fastening element 10. The connecting element 11 has a first linear guide in the form of essentially C-shaped side sections 16, which engage around laterally projecting guide rails 15 of the fastening element 10.

In the embodiment shown, an actuating element 13 in the form of a slider 13a is provided for opening a locked connection between the fastening element 10 and the connecting element 11, which is slidably mounted on a cover or a housing 14 of the storage device 1 in the displacement direction 12 of the connecting element 11. The cover 14 can be used in particular to prevent snow or the like from penetrating the connection between the connecting element 11 and the fastening element 10.

Especially in Fig.2 it can be seen that the cover or the housing 14 are connected to both the fastening plate 10 and the connecting element 11 via a linear guide. The cover 14 surrounds the C-shaped side sections 16 of the connecting element 11 with outer side walls 14a extending essentially perpendicular to a surface of the ski. In order to reliably connect the cover 14 to the fastening element 10, laterally projecting guide rails 17 are provided in the rear section of the cover 14 facing the ski binding, which are at least partially received in grooves 18 of a second linear guide of the connecting element 11. The cover 14 thus surrounds the connecting element 11 in a front area and is received in a rear area on the inside in a linear guide or by grooves 18 of the connecting element 11, so that a reliable (sliding) connection between the two elements 11 and 14 is achieved.

In order to fix the cover 14 in a state when pushed onto the fastening element 10 without separate fixing elements in a simple manner, the cover 14 has a front edge 14b which, in the pushed-on state, is received in a locking recess 10a of the fastening element 10. The cover 14 is easily fixed from the front, ie in the assembled state the ski binding and the storage device away from the tip of the ski, in the direction 9' on the fastening element 10 until the front edge 14b of the cover 14 snaps into the locking recess 10a. In order to simplify the elastic deformation of the cover during the sliding on process, the cover 14 has a groove or slot 19 on the bottom side, running transversely to the sliding on direction, which promotes an elastic upward pivoting of a front end section of the cover 14. When the cover 14 is pushed on, it strikes a front blocking surface 10c of the fastening element 10.

What next Fig.1 As can be seen, the connecting element 11 is connected to the binding element 5 via connection elements 20 in the form of two projections 20a, which are accommodated in corresponding recesses 20b in the binding element 5 of the ski binding 2. In this way, existing ski or cross-country bindings 2, which are slidably mounted on a slide rail 4, can be easily retrofitted with a storage device 1 in order to be able to change the position of the ski binding 2 on the ski or on the slide rail 4 without having to get out of the ski binding 2 with a boot accommodated in it. An existing locking connection between the ski binding 2 and the slide rail 4 arranged underneath is removed for this purpose in order to enable the ski binding 2 or the binding element 5 to be freely slidably mounted on the slide rail 4. Instead of the previously provided locking element, a simple cover plate 21 can be provided.

In the Fig. 2 to 6 In particular, a locking device 22, with which the connecting element 11 can be firmly connected to the fastening element 10 in a locking position, can be seen in detail. The connecting element 11 and thus also the ski binding can be fastened to the ski 3 in two different positions via the locking device 22. In Fig. 2A the connecting element is shown in a rear functional position shifted in the direction of arrow 9', ie towards the end of the ski, a so-called sliding position, in which the sliding behavior of the ski is improved, which is particularly advantageous when descending, whereas in Fig. 2 the connecting element 11 and thus the ski binding 2 in a front functional position shifted in the direction of arrow 9, ie towards the tip of the ski, in a so-called push-off or grip position, in which the push-off or grip behavior of the ski is improved and which is particularly advantageous when climbing.

To produce a fixed or immovable connection between the connecting element 11 and the fastening element 10, the locking device 22 has an actuating element 13 with a slider 13a, via which two locking pins 23a provided as locking elements 23 can be released from recesses 24a, 24b in the connecting element 11. The actuating element 13 is provided for transferring between a locking position and an open position of the locking device 22, which in the first embodiment comprises a slotted guide 25. The slotted guide 25 has two arcuate sections 26a, 26b, each of which is provided for receiving a guide pin 23b of a locking pin 23a. If the guide pins 23b are arranged at an outer vertex of the arcuate sections 26a, 26b, the locking pins 23a are arranged in an outwardly displaced locking position in which the outer ends of the locking pin 23a are received in the recesses 24a or 24b according to one of the two functional positions of the connecting element 11. When the link guide 25 is displaced via the slide 13a, which is slidably mounted on the cover 14, the guide pins 23b are received in an inner front or rear end section of the respective arcuate sections 26a, 26b of the link guide 25. The locking pins 23a are thus pivoted and their outer ends are displaced inwards so that the locking pins 23 are arranged in an open position in which they do not come into contact with the recesses 24a, 24b, whereby the connecting element 11 is freely displaceable relative to the fastening element. The link guide 25 can be displaced forwards or backwards via the slide 13a against the force of a spring 27 depending on whether a displacement of the connecting element 11 forwards, in the direction of arrow 9, or backwards, in the direction of arrow 9', is desired; in both cases the guide pins 23b is displaced inwards and the locking pins 23a are thus moved into their open position. The spring 27, which is compressed during the actuation of the slide 13a and is connected to the cover 14, returns to its relaxed rest position in a non-activated state, whereby the guide pins 23b return to the vertices of the arcuate sections 26a, 26b and thus to their locking position.

To unlock from one functional position, move the connecting element 11 or the ski binding 2 and lock it again in the other functional position, the following movement sequence is preferably carried out: i. Unlocking by pushing the slider 13a against the force of the spring 27; ii. Moving the ski binding 2 with the help of the foot, which is held in the ski binding 2 via a ski boot; iii. Releasing the slider 13a; iv. Automatic engagement of the locking pins 23a in the recess 24a or 24b, provided the connecting element 11 is moved (with the foot) into the corresponding position.

In Fig.7 , 7a and 7b a second embodiment is shown in which the connecting element 11 is formed in one piece with the front binding element 5; ie the connecting element 11 extends from a front end of the binding element 5 forwards in the direction of the ski tip. Unlike the first embodiment, such a design is not intended for retrofitting existing bindings, but is originally intended for use with the storage device 1 according to the invention.

The front binding element 5, which in turn has a receptacle 6 for a pivot axis of a shoe, is slidably mounted together with the connecting element 11 on the slide rail 4. For a heel contact, a rear binding element 8 together with the slide rail 4a can be used as in Fig.1 shown.

Similar to the first embodiment, a cover or housing 14 is provided. Unlike the first embodiment, however, the housing 14 is not attached to a separate fastening element 10, but via a snap-in connection connected to the slide rail 4 connected to the ski surface. For this purpose, the slide rail 4 has a locking bar 30 with several locking openings which interact with an elastically mounted locking projection 31 in the housing 14. The housing 14 is pushed onto the slide rail 4 via a linear guide and can be fastened to a ski in different positions via a locking connection between the locking bar 30 and the locking projection 31. In order to show the user the position of the housing 14, an index bar 32 is provided on the slide rail 4. The housing 14 also has a recess 33 in the area in which the index bar is basically covered by the housing 14, so that the recess 33 allows a limited view of the index bar 32, and thus the position of the housing 14 on the slide rail 4 is recognizable to the user.

As in particular in Figures 7a and 7b As can be seen, the locking device 22 in the second embodiment is identical to that in the first embodiment. To avoid repetition, reference is therefore made to the above explanations with regard to the structure and mode of operation.

The essential difference between the first and the second embodiment is that the second embodiment has a double adjustability. On the one hand, a kind of basic setting is made by positioning the housing 14 on the slide rail 4, whereby the position of the ski binding 2 can then be changed in a simple manner between a front push-off or grip position and a rear sliding position using the storage device 1 according to the invention.

In the Figures 8 and 8a a third embodiment is shown. In this embodiment too - as in the second embodiment - the connecting element 11 is formed in one piece with the (front) binding element 5. In this embodiment, however, a differently constructed locking device 22 is provided, via which the connecting element 11 and thus the binding element 5 can be arranged in different positions on a ski. Of course In this embodiment, the binding element 5 is also slidably mounted on a slide rail 4.

In the third embodiment, as in the first two embodiments, a slide 13a displaceably mounted on the housing 14 is provided as the actuating element 13, which can be displaced forwards in the direction 9 or backwards in the direction 9' against the force of a spring 27.

Instead of the slotted guide 25 provided in the first two embodiments, a toggle lever 35 is provided in this embodiment. The toggle lever 35 comprises two lever elements 35a on which the locking pins 23a are rotatably mounted. When the slider 13a is moved, a receptacle 35b with a central axis of rotation 35c of the two lever elements 35a is thus moved, whereby the lever elements 34a pivot and locking pins 23a pivotably mounted on the lever elements 35a are moved out of the respective recesses 24a or 24b. When the slider 13a is released, the central axis of rotation 35c moves back to its middle position and the lever elements 35a pivot into the extended starting position in which the locking pins 23a are arranged in their locking position. The operating method for the user is therefore the same as described above in connection with the slotted guide 25.

In the Figures 9 and 9a a fourth embodiment is shown. In this embodiment too - as in the second and third embodiments - the connecting element 11 is formed in one piece with the (front) binding element 5. In this embodiment, however, a differently constructed locking device 22 is provided, via which the connecting element 11 and thus the binding element 5 can be arranged in different positions on a ski. Of course, in this embodiment too, the binding element 5 is slidably mounted on a slide rail 4.

Instead of the slider 13a which is displaceably mounted in the direction of displacement 9, 9` - as in the first three embodiments is provided - the fourth embodiment has a pusher 36 that can be actuated transversely to the direction of displacement 9, 9' as the actuating element 13. The pusher 36 has two pressure elements 36a, 36b, with an inner pressure element 36b being slidably received in an outer pressure element 36a. The spring 27 is arranged between the two pressure elements 36a, 36b transversely to the direction of displacement 9, 9', so that when the spring 27 is not activated, the two pressure elements 36a, 36b are arranged in an outwardly displaced locking position via the spring. The two pressure elements 36a, 36b each have projections on their lower, outer edges that form locking pins 23a, which in the locking position - depending on the functional position - are received in recesses 24a or 24b. The pressure elements 36a, 36b are connected to one another via a drive plate 36c, which has a central pivot axis 36d and a drive pin 36e. The drive pin 36e is a rotary mount 37a in the inner pressure element 36b and is received in a guide slot 37b in the outer pressure element 36a. The central pivot axis 36d is received in a corresponding rotary mount in a pusher housing 38, so that the pressure elements 36a, 36b are moved inwards or outwards in a synchronized manner via the drive plate 36c. The pusher housing 38 is connected to the housing 14 via screws 38a.

Instead of the sliding movement to activate the slider 13a in the first three embodiments, in the fourth embodiment a user only has to press the pressure elements 36a, 36b inwards to release the locking pins 23a from their locking position. The remaining functionality for adjusting the ski binding between the two functional positions is the same as already described above.

In Fig.10 a fifth embodiment is shown. In this embodiment, the actuating element 13 is a slide 13a with a toggle lever 35 for transferring the locking pins 23a between a blocking and an open position, the functioning of which has already been explained in detail in connection with the third embodiment; in order to avoid repetition, reference is made to the above Explanations referred to.

The essential difference to the third embodiment is that, viewed in the direction of displacement 9, 9', the position of the ski binding 2 or the binding element 5 can be adjusted not only by the quick adjustment via the storage device 1 according to the invention, but also by a locking device known per se, as is described in detail in the WO2017/220771 A1 disclosed, may be provided.

Accordingly, the connecting element 11 has an extension or fastening section 11a, which is accommodated between the slide rail 4 and the binding element 5 and has a locking bar 11b with locking connection elements, in particular in the form of a perforated bar. The binding element 5, which is slidably mounted on the slide rail 4, has an operating element 39, which can be transferred between an open and a closed position and interacts with a locking or holding element 40 on the binding side. In the closed position of the operating element 39, the locking or holding element 40 is in engagement with the locking bar 11b, so that the position of the binding element 5 on the slide rail 4 and thus on the ski is defined.

With this embodiment, a double adjustability of the position of the ski binding 2 or the binding element 5 on the slide rail 4 or the ski 3 is possible: On the one hand, a quick adjustment can be made between a front push-off or grip position corresponding to the recesses 24b and a rear sliding position corresponding to the rear recesses 24a while a ski boot is accommodated in the ski binding 2; on the other hand, a fine adjustment can be achieved due to different positions of the binding element 5 relative to the locking bar 11b in the locked position.
