Description

The invention relates to a ski binding with two binding jaws, a mechanically releasable front jaw and a mechanically releasable heel jaw, one of the two binding jaws being slidably displaceable on the ski in the longitudinal direction of the ski,
wherein the binding jaw, which can be arranged so that it can slide, can be connected to a connecting element which is operatively connected via an actuating element to an electronically controllable release unit located between the two binding jaws, wherein the actuating element is held within the release unit by a blocking device when the ski binding is ready to ride, which in the case of an electronic Triggering releases the actuator together with the connecting element to move the binding jaws while increasing the mutual distance between the two binding jaws.

Such a ski binding with an electronically controlled release unit is, for example, from EP 1 378 275 B1 known. In this known ski binding, two bearing parts are arranged on the ski, on which a binding plate is located. Two binding jaws, each ensuring a safety release, are arranged on the binding plate, with the front jaw being slidably arranged on the binding plate in the longitudinal direction of the ski and being connected via a binding connection element to the electronically controlled release unit, which is located between the binding jaws. A force measuring system is accommodated within one bearing part, which measures the forces occurring between the plate and the ski and transmitted from the skier to the ski. The force measurement system is followed by evaluation electronics, which are preferably accommodated in the binding plate and which, depending on the measured forces and comparative values, activate the release unit actuated, so that when triggered, the toe piece is pushed forward to a limited extent via the binding connection element. The evaluation electronics and their power supply are housed within the binding plate. The mounting of the binding plate on the ski ensures that the ski can sag when driving through troughs and the like. This known ski binding is bulky, mainly due to the binding plate, and has a relatively large overall height. Measures to enable the ski binding to be adapted to different ski boot sizes are not disclosed.

The invention is based on the object of using simple measures to enable the ski binding to be adapted to different ski boot sizes and largely unhindered deflection of the ski when driving through troughs and the like in a ski binding of the type mentioned at the outset that is provided with an electronic release system.

The stated object is achieved according to the invention in that the connecting element is embodied as an elongate band-like design, with either the actuating element being positionable in relation to the connecting element or the binding jaw which can be slidably arranged in relation to the connecting element in different longitudinal positions.

These simple alternative measures ensure that the binding jaws of the ski binding provided with an electronic release system can not only be adapted to the length of the ski boot to be used in each case, but also that better deflection of the ski is possible at the same time.

In a preferred embodiment, the actuating element is firmly connected to a spring-loaded intermediate part. In the event of an electronic release, the spring or the springs support a displacement of the binding jaw that can be arranged in a sliding manner.

In the embodiment in which the actuating element can be positioned in different longitudinal positions relative to the connecting element, the intermediate part is designed as a clamping element which can be latched and fixed in different longitudinal positions on the connecting element. In this embodiment, therefore, the longitudinal adjustment of the binding to adapt to different ski boot sizes is easily accessible in the middle between the binding jaws, the heel jaw is firmly connected to the connecting element in this embodiment.

A configuration is particularly preferred in which the connecting element has a central band-shaped connecting arm, which is firmly connected to the slidably attachable binding jaw, and two band-shaped side arms, which are provided with rows of holes with pairs of holes for fixing the intermediate part.

In the alternative, in which the binding jaw, which can be arranged in a sliding manner, can be positioned in different longitudinal positions relative to the connecting element, the connecting element is firmly connected to the intermediate part in a continuation of the actuating element.

In this embodiment, the binding jaw that can be slidably arranged can be arranged in different longitudinal positions on the connecting element in a simple manner, in that the connecting element has a toothed strip or is firmly connected to a toothed strip, to which the binding jaw that can be arranged slidably can be fixed in different longitudinal positions by means of a locking lever.

In further preferred embodiments, when triggered electronically, the actuating element together with the connecting element can be released either by igniting a pyrotechnic capsule or by releasing a magnetic holding device. In both variants, electronic triggering can therefore take place without any significant time delay and is therefore particularly reliable. The use of a pyrotechnic capsule is particularly advantageous in this respect. In this case, further electronic triggering is only possible by inserting a new pyrotechnic capsule possible, which can be carried out, for example, as part of a ski or binding service. This special feature does not weigh particularly heavily, as the two binding jaws still ensure a mechanical safety release.

In a further advantageous embodiment of the ski binding, the blocking device has two release levers, which are articulated on axes running perpendicular to the upper side of the ski, hold the actuating element in the ready position and are held by a slide, which is released for movement in the longitudinal direction of the ski when triggered electronically thereby releasing the release lever and, via this, the actuating element. The two release levers and the slide therefore mainly ensure that the release unit remains "blocked" until the conditions for an electronic release are met.

According to a further particularly advantageous embodiment of the invention, the triggering unit has a mechanical repeating device, by means of which the triggering unit can be returned manually after electronic triggering to its starting position, in which mechanical triggering of the binding jaws is ensured. The user of the ski binding is therefore able, after an electronic release, to ensure in a simple manner that it is possible to continue driving or to continue using the ski binding, which ensures a conventional mechanical safety release in any case.

Advantageously, the two release levers in the ready-to-drive position hold a locking part which is firmly connected to the actuating element and which connects the actuating element to a repeating slide of the repeating device. Preferably, the repeater slide is operatively connected to the release levers via control paths in such a way that, after electronic release has taken place, these can be returned to their starting position by moving the displaced binding jaw back.

An electronic unit, which is connected to the pyrotechnic capsule or the magnetic holding device, in particular via a cable, ensures that the pyrotechnic capsule is ignited or released via the magnetic holding device and is Ski is housed outside of the binding jaws or in the binding area below a binding jaw or in a binding plate and receives and gives signals to release the connecting element or the actuating element connected thereto.

The pyrotechnic capsule or the magnetic holding device is preferably accommodated in the triggering unit.

The binding jaw connected to the connecting element and slidably displaceable in the longitudinal direction of the ski is, according to a preferred embodiment variant, the heel jaw. It has been shown that in most falls that should result in an electronic release, a particularly safe and quick release of the skier from the ski is ensured by shifting the heel piece. A displacement of the order of 14.00 mm to 20.00 mm is sufficient and advantageous.

Like for example Figures 1 and 2 A ski binding is mounted on a ski 1, which is a safety ski binding with two binding jaws, a front jaw 2 and a heel jaw 3. Both the front jaw 2 and the heel jaw 3 are each equipped with a release mechanism that ensures a safety release. An electronically actuable release unit 8 is located between the front jaw 2 and the heel jaw 3. A flat box 22 is fastened to the top of the ski in front of the front jaw 2, which box contains an electronic unit 23 which has a receiving unit for radio signals. In the box 22 there is also a power supply, in particular replaceable and rechargeable batteries. The electronic unit 23 is connected to a pyrotechnic capsule 21 ( 7 ) or with a magnetic holding device 26 ( 10, 11 ) tied together. The electronic unit 23 receives radio signals on the basis of electronically processed sensor data, which originate, for example, from sensors that record the movements of the skier and how they change over time, so that when certain sensor data or data combinations are present, the unit 23 can ignite the pyrotechnic capsule 21 or a release of the magnetic holding device 26 is effected, as a result of which one of the two binding jaws is displaced in the longitudinal direction of the ski, increasing the mutual distance between the two binding jaws.

As also 1 and 2 each binding jaw 2, 3 is arranged on a base plate 4, 5 mounted on the ski 1. In the exemplary embodiment shown, the front jaw 2 is fixedly attached to a base plate 4, the heel jaw 3 is arranged so that it can slide in the longitudinal direction of the ski on a guide rail 6 screwed to a base plate 5 .

The tripping unit 8 is located in a housing 11, which has a plate-shaped upper part 11a and a plate-shaped lower part 11b ( Figures 6 and 7 ), which are connected to each other running parallel to each other and to the top of the ski and between which the components of the triggering unit 8 are located.

The trigger unit 8 is in accordance with the embodiment by means of a Figures 1 to 9 connected to the heel piece 3 by a connecting element 7 which is Y-shaped in plan view. The connecting element 7 has three arms 7a, 7b running parallel to one another and in the longitudinal direction of the ski as well as straight—two band-shaped side arms 7a and a central band-shaped connecting arm 7b—( Figure 4, Figure 5 ). The two side arms 7a branch off from the middle connecting arm 7b and run laterally into the triggering unit 8 . The connecting arm 7b extends below the guide rail 6 to a latching element 9, which engages through a recess in the guide rail 6 with a latching lever of the heel piece. The free end of the connecting arm 7b is firmly connected to the locking element 9, in particular riveted. The configuration is such that the heel piece 3 can be moved relative to the guide rail 6 together with the connecting element 9 .

The two side arms 7a of the connecting element 7 are each provided with a row of holes made up of a number of equally spaced holes 10, which belong together in pairs, since the rows of holes are symmetrical with respect to the longitudinal axis of the connecting arm 7b running in the longitudinal direction of the ski. The mutual spacing of the holes 10 in each row of holes corresponds to the difference in length of sole lengths of ski boots of different shoe sizes, so that the position of the heel piece 3 relative to the toe piece 2 can be varied to adapt to a specific ski boot sole length, as described below. 1 and 2 show different settings of the mutual distance between the toe piece 2 and the heel piece 3, 1 for a ski boot with a longer sole length, 2 for a ski boot with a shorter sole length.

The components of the tripping unit 8 include an elongate actuating element 12 ( Figures 3 to 6 ), the in driving condition ( 4 , 6 ) is held within the tripping unit 8 by a blocking device. The actuating element 12 extends in the longitudinal direction of the ski and centrally between and parallel to the two side arms 7a, and therefore has an end facing the heel piece 3, which protrudes from the housing 11, and an end located inside the housing 11. The end of the actuating element 12 protruding from the housing 11 is fastened to an intermediate part 13 which has an upper and a lower clamping element 13a, 13b. In the embodiment shown, the actuating element 12 is connected to the upper clamping element 13a ( 6 ) riveted. The upper clamping element 13a engages over the two side arms 7a from above, the lower clamping element 13b. The upper clamping element 13a is provided with two lateral pins which are inserted through the holes 10 of a pair of holes and engage in recesses of the lower clamping element 13b. A screw 14 allows a firm but detachable connection of the two clamping elements 13a, 13b. In an alternative embodiment, the lower clamping element 13b is provided with the lateral pins.

In order to adjust the mutual distance between the toe piece 2 and the heel piece 3, the screw connection to the lower clamping element 13b is loosened, the upper clamping element 13a is lifted out of the holes 10 and the heel piece 3 is moved to the desired position, with the connecting element 7 depending on whether the The distance between the toe piece 2 and the heel piece 3 is increased or decreased, something emerges from the housing 11 or is pushed into the housing 11 accordingly. The upper clamping element 13a is in turn connected to the lower clamping element 13b after engagement of the pins in the corresponding pair of holes and the screw 14 is tightened.

The intermediate part 13 is under the pressure of two helical compression springs 15 ( Figures 4 to 6 ) which are next to the actuating element 12 and running parallel to this with their one end on the intermediate part 13 and with their second ends on housing-fixed abutments, which are not visible in the figures, supported.

The heel jaw 3 opposite end of the actuating element 12 is by means of a locking part 17 with a repeating slide 16, which is the main part of a Repeating device is connected. In the example shown, the blocking part 17 is the rivet head 17a of a rivet. The repeater slide 16 is a plate-shaped component running parallel to the upper side of the ski, with two lateral slide arms 16a, at the ends of which a control track 16b is formed, the control tracks 16b running in a V-shape relative to one another. Above the helical compression springs 15 and the repeating slide 16, parallel to the upper side of the ski and at a distance from one another, are two release levers 18 ( 6 ), which are movably articulated at one end to the end regions of the housing 11 facing the heel jaw 3 about axes running perpendicularly to the upper side of the ski, in particular formed by rivets. The two release levers 18 are held in the ready position of the ski binding by a slide 19 that also belongs to the blocking device. On the mutually facing longitudinal sides of the release lever 18 there is a nose-like projection 18a, by means of which the rivet head 17a, which forms a locking part, is gripped behind when the ski binding is ready to ride, so that the actuating element 12 is held in position when the ski binding is ready to ride. The release levers 18 each have an upwardly projecting retaining lug 18b at their second ends.

Like it in particular 6 shows, the slide 19 is located near the toe piece 2 within the housing 11, essentially above the end sections of the release lever 18 facing the toe piece 2. The slide 19 is movably mounted on the housing 11 in the longitudinal direction of the ski and is laterally supported by a retaining spring 20, which each is a helical compression spring, acted upon, which are supported with their one ends in each case on a first support projection of the housing lower part 11b and with their other ends on abutments 19a projecting laterally from the slide 19. The two retaining springs 20 press the slider 19 in the direction of the front jaw 2 and against second support lugs on the lower housing part 11b.

The slide 19 is provided with a recess in the middle, which has two supporting edges 19b at the edge, slightly spaced apart from one another and oriented in the longitudinal direction of the ski, on which the two retaining lugs 18b of the release lever 18 are supported when the ski binding is ready to ride, so that the two release levers 18 are in one mutually pressed position and hold the rivet head 17a. In the direction of the front jaws 2, the supporting edges 19b are adjoined by deflection recesses 19c, which are local widenings of the recess. Immediately in front of the slide 19, a receptacle is formed in the housing 11, in which the pyrotechnic capsule 21 is inserted.

The ignition of the pyrotechnic capsule 21 causes the slide 19 to move abruptly against the force of the two retaining springs 20 in the direction of the heel jaws 3. The retaining lugs 18b of the two release levers 18 come free from the supporting edges 19b of the slide 19 and "fall" into the avoidance depressions 19c ( 7 , 8 ) so that the two release levers 18 pivot outwards about their axes, in the direction of the side edges of the ski, and the rivet head 17a is released from the nose-like projections 18a of the release levers 18, so that the actuating element 12 that has now been released moves the heel jaws 3 on the guide rail 6 backwards via the connecting element 7 moves. The individual components and their freedom of movement are designed in such a way that the displacement path Δ is dimensioned in such a way that the ski boot can be released from the ski binding immediately. The displacement Δ ( 3 ) is particularly and preferably 14.00 mm to 20.00 mm.

To return the triggering unit 8 to the ready-to-drive state, the heel piece 3 is pushed by hand on the guide rail 6 in the direction of the toe piece 2, with the actuating element 12 and thus the repeater slide 16 connected to the actuating element 12 also being moved in the direction of the toe piece 2 via the connecting element 7 becomes. The control tracks 16b on the bolt-action slide 16, which run towards one another in a V-shape, grasp the retaining lugs 18b of the release lever 18 located in the deflection depressions 19c from the outside ( 9 ) and slide them back along the control tracks 16b to their starting positions on the support edges 19b. At the same time, the two release levers 18 pivot back into their starting positions, the rivet head 17a latches again in front of the nose-like projections 18a of the release lever 18.

In the first embodiment variant, the triggering unit 8 can only trigger again electronically when a new pyrotechnic capsule 21 has been inserted.

In an alternative, in Figures 10 and 11 In the embodiment variant of the triggering unit 8 shown, a magnetic holding device 26 is provided instead of a pyrotechnic capsule. The other components of the tripping unit 8 largely correspond to those in Figures 1 to 9 shown version. In Figures 10 and 11 of these components, the release lever 18 with its retaining lugs 18b, the slide 19 and the repeating slide 16 can be seen. The magnetic holding device 26 comprises a switchable, electrically deactivatable permanent magnet 27 which acts on an anchor plate 28 which is arranged on the slide 19 . Instead of the retaining springs 20 provided in the first embodiment, compression springs 29 are installed, each of which is supported with its one end near the anchor plate 28 on abutments 30 formed on the housing 11 and with its second end on abutments 31 formed on the Schieber19. In running order ( 10 ) of the ski binding, the permanent magnet 27 holds the anchor plate 28 and thus the slide 19. When triggered, the anchor plate 28 and thus the slide 19 are released by a brief current pulse acting on the permanent magnet 27. As a result, the slide 19 moves, supported by the compression springs 29, in the direction of the heel piece 3, whereby, analogously to the first embodiment, the actuating element 12 that has been released pushes the heel piece 3 backwards on the guide rail 6 via the connecting element 7, supported by the springs 15. The resetting of the triggering unit 8 into the ready-to-drive state takes place analogously to the first embodiment, with the triggering unit 8 being ready for use again after it has been returned.

At the in Figures 12 to 15 In the embodiment variant shown, two binding plates 4', 5' are provided which are to be fastened to the upper side of a ski (not shown) and are designed like rails in a known manner, so that the binding jaws 2, 3 can be pushed onto the binding plates 4', 5'. The in the Figures 12 to 14 The indicated release unit 8 can be designed as described with reference to the previous figures and is mounted on the rear end section of the front binding plate 4' in the exemplary embodiment shown. On the upper side of the front binding plate 4', a rack 32 is fastened so that the front binding jaw 2 opens after it has been slid on the binding plate 4' can be fixed in a specific longitudinal position in a known manner. A toe piece 2 that is mounted and adjusted in its position remains in this position on the binding plate 4'.

An intermediate part 13 ′ is also provided in this embodiment variant, which is in particular also located outside of the triggering unit 8 and is firmly connected to the actuating element 12 of the triggering unit 8 . How in particular 12 to 14 show, the intermediate part 13' is spring-loaded, in particular by two helical compression springs 15 which are arranged on the side of the actuating element 12 and are arranged analogously to the first embodiment. The intermediate part 13' is firmly connected to a connecting element 7', which essentially runs as a continuation of the actuating element 12. The connecting element 7' extends centrally along the top of the rear binding plate 5'. A further, rear rack 33 connects to the connecting element 7' and is firmly connected to the connecting element 7'. On the upper side of the rack 33 there is a row of grid elevations 33a. In alternative embodiments, the rack 33 is fastened to the connecting element 7' or is a component part of the connecting element 7', which in this case has a correspondingly long design. A recess 5'a formed centrally along the upper side of the binding plate 5' is intended to accommodate the connecting element 7' and the rack 33, the connecting element 7' together with the rack 33 being and remaining longitudinally displaceable relative to the binding plate 5'.

12 shows a position in which the actuating element 12 is held within the triggering unit 8, 13 the position after a triggering, for example by igniting the pyrotechnical capsule in the triggering unit 8, as a result of which the actuating element 12 is released and the connecting element 7' together with the toothed strip 33 is pushed backwards.

14 shows a toe piece 2 attached to the front binding plate 4' and a heel piece 3 arranged on the rear binding plate 5', the ready-to-drive position, as also shown in FIG 12 shown is shown. The sectional view in 15 shows that the heel piece 3 is locked in a selectable position on the rack 33 by means of a locking lever 34 that can be actuated from the rear of the heel piece 3 . The detent lever 34 is spring-loaded in a known manner by a helical compression spring 35 . The heel piece 3 can thus be pushed into the desired longitudinal position in relation to the toe piece 2 after the locking lever 34 has been lifted and released from the rack 33 on the binding plate 4'. By lowering the locking lever 34, it engages in the toothed strip 33. In this way, the heel piece 3 together with the toothed strip 33 and the connecting element 7' can be pushed backwards in the longitudinal direction of the binding plate 5', as described, and then when the actuating element 12 is released can be moved back to its original position, the ready-to-drive position.

A ski binding according to the invention is attached to both skis of a pair of skis. The electronic units 23 are switched on by the skier at the start of skiing, for example by switching it on manually. The electronic units 23 on the skis can also be put into operation via switches that are actuated by the ski boots when stepping into the ski bindings. An electronic release occurs simultaneously for both bindings.

In principle, the release system can be used in ski binding systems with two binding jaws, even in those in which the binding jaws are on binding plates. The release unit can also be designed in a different way in order to cause a displacement of one binding jaw in the longitudinal direction of the ski.
