SKI BINDING

Description

[0001] The invention relates to a ski binding with two binding jaws, a mechanically releasable toe jaw and a mechanically releasable heel jaw, wherein one of the two binding jaws can be arranged on the ski so as to be slidably displaceable in the longitudinal direction of the ski, wherein the slidably arranged binding jaw can be firmly 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 and fixed with respect to the non-sliding binding jaw, wherein the actuating element, in the ready-to-use state of the ski binding, is held within the release unit by a blocking device which, upon electronic release, releases the actuating element together with the connecting element for displacement of the binding jaw while increasing the mutual distance between the two binding jaws.

[0002] Such a ski binding with an electronically controlled release unit is known, for example, from EP 1 378 275 B1. 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 safe release, are arranged on the binding plate. The toe jaw is arranged on the binding plate so that it can slide in the longitudinal direction of the ski and is connected via a binding connection element to the electronically controlled release unit located between the binding jaws. A force measuring system is housed within one of the bearing parts, which measures the forces occurring between the plate and the ski and transmitted to the ski by the skier.The force measuring system is followed by evaluation electronics, which are preferably housed in the binding plate. These electronics actuate the release unit based on the measured forces and comparison values, so that, in the event of a release, the toe piece is moved 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 flex when negotiating hollows and the like. This known ski binding is bulky and has a relatively high overall height, primarily due to the binding plate. Measures to enable the ski binding to be adjusted to different ski boot sizes are not disclosed.

[0003] DE 20 2006 020 500 U1 discloses a ski binding with a mechanically releasable toe piece and a mechanically releasable heel piece. One of the two binding pieces is arranged on the ski so as to be slidably displaceable in the longitudinal direction of the ski. The slidably arranged binding piece is connectable to a connecting element, which is operatively connected via an actuating element to an electronically controllable release unit located between the two binding pieces. The connecting element is designed as an elongated, band-shaped plate, and the slidably arranged binding piece can be positioned in different longitudinal positions relative to the connecting element.

[0004] US 2008 / 197607 A1 discloses a ski binding with a toe piece and a heel piece. The heel piece is slidably displaceable on the ski in the longitudinal direction of the ski and is connected to a connecting element, which is operatively connected via an actuating element to an electronically controllable release unit located between the two binding pieces. When the ski binding is in the ready-to-use state, the actuating element is held within the release unit by a blocking device, which, upon electronic release, releases the actuating element together with the connecting element to move the binding piece, increasing the mutual distance between the two binding pieces. In this design, the connecting element is designed as an elongated, band-shaped plate. The heel piece can be positioned in different longitudinal positions relative to the connecting element.

[0005] The ski binding-ski system known from US Pat. No. 6,659,494 B1 includes a pivoting heel attachment plate and a toe piece connected to the ski, with a rail arranged on the heel attachment plate. A release actuating element is connected to the rail to adjust the distance between the toe piece and the heel piece by sliding the heel piece backward on the rail. The release actuating element comprises a cylinder with a release piston.

[0006] EP 2 883 581 A1 relates to an electronically releasable binding for a gliding board with a toe piece and a heel piece. A controller with an evaluation device for evaluating sensor signals from sensors to generate a release signal is provided. An actuator that can be triggered via a release signal is coupled to the evaluation device. A coupling element connected to one of the two binding pieces forms a coupling interface with the actuator, which mechanically connects the actuator to the coupled binding piece, at least when triggered.

[0007] The invention is based on the object of enabling, with simple measures, an adjustment of the ski binding to different ski boot sizes and a largely unhindered deflection of the ski when passing through hollows and the like in a ski binding of the type mentioned at the outset which is provided with an electronic release system.

[0008] The object is achieved according to the invention in that the connecting element is designed to be elongated and band-shaped overall, wherein the actuating element can be positioned in different longitudinal positions relative to the connecting element.

[0009] These simple measures ensure that the binding jaws of the ski binding, which is equipped with an electronic release system, can not only be adjusted to the length of the ski boot being used, but also that a better deflection of the ski is possible at the same time.

[0010] In a preferred embodiment, the actuating element is firmly connected to a spring-loaded intermediate part. The spring(s) assist in the movement of the sliding binding jaw during electronic release.

[0011] Preferably, the intermediate part is designed as a clamping element that can be locked and fixed to the connecting element in various longitudinal positions. In this design, the longitudinal adjustment of the binding to accommodate different ski boot sizes is easily accessible centrally between the binding jaws. In this configuration, the heel jaw is firmly connected to the connecting element.

[0012] Particularly preferred is an embodiment in which the connecting element has a central band-shaped connecting arm, which is firmly connected to the slidably arranged binding jaw, and two band-shaped side arms, which are provided with rows of holes with pairs of holes for fixing the intermediate part.

[0013] In further preferred embodiments, with electronic release, the actuating element, including the connecting element, can be released either by igniting a pyrotechnic capsule or by releasing a magnetic holding device. With both variants, electronic release can therefore occur without any significant time delay and is therefore particularly reliable. The use of a pyrotechnic capsule is particularly advantageous in this regard. In this case, further electronic release is only possible by inserting a new pyrotechnic capsule, which can be done, for example, during a ski or binding service. This special feature is not particularly significant, since the two binding jaws still ensure a mechanical safety release.

[0014] In a further advantageous embodiment of the ski binding, the locking device has two release levers, which are hinged on axes running perpendicular to the top of the ski. These release levers hold the actuating element in the ready-to-use position. They are held by a slider, which, upon electronic release, is released for movement in the longitudinal direction of the ski, thereby releasing the release levers and, through them, the actuating element. The two release levers and the slider therefore primarily ensure that the release unit remains "blocked" until the conditions for electronic release are met.

[0015] According to another particularly advantageous embodiment of the invention, the release unit has a mechanical repeating device, by means of which the release unit can be manually returned to its starting position after electronic release, in which mechanical release of the binding jaws is ensured. The user of the ski binding is therefore able to easily ensure that continued skiing or use of the ski binding is possible after electronic release, which a conventional mechanical safety release always guarantees.

[0016] In the ready-to-use position, the two release levers advantageously hold a locking part that is firmly connected to the actuating element, which connects the actuating element to a repeating slide of the repeating mechanism. Preferably, the repeating slide is operatively connected to the release levers via control tracks, such that, after electronic release, they can be returned to their original position by reversing the displaced binding jaw.

[0017] An electronic unit ensures that the pyrotechnic capsule is ignited or released via the magnetic holding device, which is connected, in particular via a cable, to the pyrotechnic capsule or the magnetic holding device and is located on the ski outside the binding jaws or in the binding area below a binding jaw or in a binding plate and receives and sends signals to release the connecting element or the actuating element connected to it.

[0018] Preferably, the pyrotechnic capsule or the magnetic holding device is accommodated in the triggering unit.

[0019] The binding jaw, which is connected to the connecting element and can be slid longitudinally along the ski, is, according to a preferred design variant, the heel jaw. It has been shown that in most falls requiring electronic release, a particularly safe and quick release of the skier from the ski is ensured by moving the heel jaw. A displacement of 14.00 mm to 20.00 mm is sufficient and advantageous.

[0020] Further features, advantages and details of the invention will now be described in more detail with reference to the partly schematic drawings, which illustrate exemplary embodiments.

[0021] For example Fig. 1 and Fig. 2Shown is a ski binding mounted on a ski 1, which is a safety ski binding with two binding jaws, a toe jaw 2 and a heel jaw 3. Both the toe jaw 2 and the heel jaw 3 are each equipped with a release mechanism ensuring a safety release. Between the toe jaw 2 and the heel jaw 3 is an electronically actuated release unit 8. In front of the toe jaw 2, on the upper side of the ski, a flat box 22 is attached, which contains an electronic unit 23 which has a receiving unit for radio signals. The box 22 also contains a power supply, in particular replaceable and rechargeable batteries. The electronic unit 23 is connected by means of an electrical cable to a pyrotechnic capsule 21 ( Fig. 7 ) or with a magnetic holding device 26 located in the trigger unit 8 ( Fig. 10, Fig. 11). The electronic unit 23 receives radio signals based on electronically processed sensor data, which originate, for example, from sensors that record the skier's movements and their change over time. Such that, when certain sensor data or data combinations are present, the unit 23 triggers the pyrotechnic capsule 21 or releases the magnetic holding device 26, whereby one of the two binding jaws is displaced in the longitudinal direction of the ski, increasing the mutual distance between the two binding jaws.

[0022] As also Fig. 1 and Fig. 2 show each binding jaw 2, 3 is arranged on a base plate 4, 5 mounted on the ski 1, in the embodiment shown the front jaw 2 is fixedly fastened to a base plate 4, the heel jaw 3 is arranged so as to be slidable in the longitudinal direction of the ski on a guide rail 6 screwed to a base plate 5.

[0023] The trigger unit 8 is located in a housing 11, which has a plate-shaped upper part 11a and a plate-shaped lower part 11b ( Figs. 6 and 7 ), which are connected to each other parallel to each other and to the top of the ski and between which the components of the release unit 8 are located.

[0024] The trigger unit 8 is actuated by means of a Fig. 1 to 9 in plan view Y-shaped connecting element 7 with the heel piece 3. The connecting element 7 has three parallel and straight arms 7a, 7b - two band-shaped side arms 7a and a central band-shaped connecting arm 7b - ( Fig. 4, Fig. 5). The two side arms 7a branch off from the central connecting arm 7b and extend laterally into the trigger unit 8. The connecting arm 7b extends below the guide rail 6 to a locking element 9, which engages with a locking lever of the heel piece through a recess in the guide rail 6. The free end of the connecting arm 7b is firmly connected, in particular riveted, to the locking element 9. The design is such that the heel piece 3, together with the connecting element 9, is movable relative to the guide rail 6.

[0025] The two side arms 7a of the connecting element 7 are each provided with a row of holes 10 equally spaced from one another, which belong together in pairs, since the rows of holes are symmetrical with respect to the longitudinal axis of the connecting arm 7b, which runs in the longitudinal direction of the ski. The mutual spacing of the holes 10 in each row of holes corresponds to the difference in sole lengths of ski boots of different boot 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. Fig. 1 and Fig. 2 show different settings of the mutual distance between the front jaw 2 and the heel jaw 3, Fig. 1 for a ski boot with a longer sole length, Fig. 2 for a ski boot with a smaller sole length.

[0026] The components of the trigger unit 8 include an elongated actuating element 12 ( Fig. 3 to 6 ), which in running order ( Fig. 4 , Fig. 6 ) is held within the release 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 ( Fig. 6) riveted. The upper clamping element 13a engages over the two side arms 7a from above, as does the lower clamping element 13b. The upper clamping element 13a is provided with two lateral pins that are inserted through the holes 10 of a pair of holes and engage in recesses in the lower clamping element 13b. A screw 14 allows a firm, yet detachable connection of the two clamping elements 13a, 13b. In an alternative design, the lower clamping element 13b is provided with the lateral pins.

[0027] 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 into the desired position. Depending on whether the distance between the toe piece 2 and the heel piece 3 is increased or decreased, the connecting element 7 protrudes slightly 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 the pins engage in the corresponding pair of holes, and the screw 14 is tightened.

[0028] The intermediate part 13 is under the pressure of two helical compression springs 15 ( Fig. 4 to 6), which are supported next to the actuating element 12 and running parallel to it with their one ends on the intermediate part 13 and with their second ends on abutments fixed to the housing, which are not visible in the figures.

[0029] The end of the actuating element 12 facing away from the heel piece 3 is connected by means of a locking part 17 to a repeating slide 16, which is the main component of a repeating device. In the example shown, the locking part 17 is the rivet head 17a of a rivet. The repeating slide 16 is a plate-shaped component running parallel to the top of the ski with two lateral slide arms 16a, at each end of which a control track 16b is formed, wherein the control tracks 16b extend in a V-shape relative to one another. Located above the helical compression springs 15 and the repeating slide 16 are two release levers 18 ( Fig. 6), which are movably hinged at one end to the end regions of the housing 11 facing the heel piece 3 about axes running perpendicular to the upper side of the ski, in particular formed by rivets. The two release levers 18 are held in the ready-to-use position of the ski binding by a slider 19 that is also part of the blocking device. On the mutually facing longitudinal sides of the release levers 18 there is each a nose-like projection 18a, by means of which the rivet head 17a forming a locking part is engaged when the ski binding is in the ready-to-use state, so that the actuating element 12 is held in its position when the ski binding is in the ready-to-use position. The release levers 18 each have an upwardly projecting retaining nose 18b at their second ends.

[0030] As is particularly the case Fig. 6shows, the slider 19 is located near the toe piece 2 within the housing 11, substantially above the end sections of the release lever 18 facing the toe piece 2. The slider 19 is mounted on the housing 11 so as to be movable in the longitudinal direction of the ski and is laterally biased by a retaining spring 20, each of which is a helical compression spring, which is supported with one end on a first support lug of the lower housing part 11b and with its other end on abutments 19a projecting laterally from the slider 19. The two retaining springs 20 press the slider 19 in the direction of the toe piece 2 and against second support lugs on the lower housing part 11b.

[0031] The slider 19 is provided with a recess in the center, which has two slightly spaced-apart support edges 19b oriented in the longitudinal direction of the ski. When the ski binding is in the ready-to-use state, the two retaining lugs 18b of the release lever 18 rest on these edges, so that the two release levers 18 are pressed toward each other and hold the rivet head 17a in place. Adjoining the support edges 19b toward the toe piece 2 are deflection recesses 19c, which are local widenings of the recess. Directly in front of the slider 19, a receptacle is formed in the housing 11, into which the pyrotechnic capsule 21 is inserted.

[0032] The ignition of the pyrotechnic capsule 21 causes an abrupt movement of the slide 19 against the force of the two retaining springs 20 towards the heel piece 3. In doing so, the retaining lugs 18b of the two release levers 18 are released from the supporting edges 19b of the slide 19 and "fall" into the deflection recesses 19c ( Fig. 7 , Fig. 8 ), so that the two release levers 18 pivot outwards around their axes, towards the ski side edges, and the rivet head 17a is released from the nose-like projections 18a of the release levers 18, so that the now released actuating element 12, via the connecting element 7, moves the heel piece 3 backwards on the guide rail 6. The individual components and their range of motion are designed such that the displacement path Δ is dimensioned such that an immediate release of the ski boot from the ski binding can occur. The displacement path Δ ( Fig. 3 ) is in particular and preferably 14.00 mm to 20.00 mm.

[0033] To return the release unit 8 to the ready-to-use state, the heel jaw 3 is pushed manually along the guide rail 6 in the direction of the front jaw 2, whereby the actuating element 12 and thus the repeating slide 16 connected to the actuating element 12 are also moved in the direction of the front jaw 2 via the connecting element 7. The control tracks 16b on the repeating slide 16, which extend in a V-shape relative to one another, engage the retaining lugs 18b of the release lever 18 located in the deflection recesses 19c from the outside ( Fig. 9 ) and guide them back to their original positions on the support edges 19b, sliding along the control tracks 16b. At the same time, the two release levers 18 pivot back to their original positions, and the rivet head 17a locks again in front of the nose-like projections 18a of the release levers 18.

[0034] In the first embodiment, the triggering unit 8 can only be triggered electronically again when a new pyrotechnic capsule 21 has been inserted.

[0035] In an alternative, in Figs. 10 and 11 In the variant of the trigger unit 8 shown, a magnetic holding device 26 is provided instead of a pyrotechnic capsule. The other components of the trigger unit 8 largely correspond to those of the Fig. 1 to 9 shown version. In Figs. 10 and 11Of 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 armature plate 28 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 one end near the armature plate 28 on abutments 30 formed on the housing 11 and with its other end on abutments 31 formed on the slide 19. In the ready-to-drive state ( Fig. 10) of the ski binding, the permanent magnet 27 holds the anchor plate 28 and thus the slider 19. When triggered, the anchor plate 28 and thus the slider 19 are released by a short current pulse acting on the permanent magnet 27. As a result, the slider 19 moves in the direction of the heel piece 3, supported by the compression springs 29, whereby, analogously to the first embodiment, the released actuating element 12 moves the heel piece 3 backwards on the guide rail 6 via the connecting element 7, supported by the springs 15. The resetting of the release unit 8 to the ready-to-use state takes place analogously to the first embodiment, whereby the release unit 8 is ready for use again after it has been returned.

[0036] At the Fig. 12 to Fig. 15In the embodiment shown, two binding plates 4', 5' are provided which are to be fastened to the upper side of a ski (not shown), which are designed in a known manner like rails, so that the binding jaws 2, 3 can be pushed onto the binding plates 4', 5'. Figures 12 to 14 The release unit 8 indicated can be designed as described in the previous figures and, in the illustrated embodiment, is mounted on the rear end section of the front binding plate 4'. A toothed strip 32 is attached to the top side of the front binding plate 4', so that the front binding jaw 2 can be fixed in a specific longitudinal position in a known manner after being pushed onto the binding plate 4'. A mounted and adjusted front jaw 2 remains in this position on the binding plate 4'.

[0037] In this embodiment, an intermediate part 13' is also provided, which is also located outside the trigger unit 8 and is firmly connected to the actuating element 12 of the trigger unit 8. As is particularly Fig. 12 to Fig. 14show, the intermediate part 13' is spring-loaded, in particular by two helical compression springs 15 arranged to the side of the actuating element 12, which 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 upper side of the rear binding plate 5'. Adjacent to the connecting element 7' is a further, rear toothed strip 33, which is firmly connected to the connecting element 7'. On the upper side of the toothed strip 33 there is a row of ratchet elevations 33a. In alternative embodiments, the toothed strip 33 is fastened to the connecting element 7' or is a component of the connecting element 7', which in this case is designed to be correspondingly long.A recess 5'a formed centrally along the upper side of the binding plate 5' is provided to receive the connecting element 7' and the toothed strip 33, wherein the connecting element 7' together with the toothed strip 33 is and remains longitudinally displaceable relative to the binding plate 5'.

[0038] Fig. 12 shows a position in which the actuating element 12 is held within the trigger unit 8, Fig. 13 the position after a triggering, for example by igniting the pyrotechnic capsule in the triggering unit 8, whereby the actuating element 12 is released and the connecting element 7' together with the toothed strip 33 is displaced backwards.

[0039] Fig. 14 shows a front jaw 2 attached to the front binding plate 4' and a heel jaw 3 arranged on the rear binding plate 5', wherein the ready-to-ride position, as in Fig. 12 The sectional view in Fig. 15 shows that the heel piece 3 is locked in a selectable position on the toothed rack 33 by means of a locking lever 34 actuated from behind the heel piece 3. The locking lever 34 is spring-loaded in a known manner by a helical compression spring 35. The heel piece 3 can thus be moved into the desired longitudinal position relative to the toe piece 2 after lifting and releasing the locking lever 34 from the toothed rack 33 on the binding plate 4'. By lowering the locking lever 34, it engages in the toothed rack 33. In this way, the heel piece 3, together with the toothed rack 33 and the connecting element 7', can be moved backward in the longitudinal direction of the binding plate 5' when the actuating element 12 is released, as described, and can then be moved back into its original position, the ready-to-use position.

[0040] A ski binding according to the invention is attached to both skis of a pair of skis. The electronic units 23 are activated by the skier at the beginning of skiing, for example, by manually switching them on. The electronic units 23 on the skis can also be activated via switches that are activated by the ski boots when stepping into the ski bindings. Electronic activation occurs simultaneously on both bindings.

[0041] The release system can generally be used with ski binding systems with two binding jaws, even those where the binding jaws are mounted on binding plates. The release unit can also be designed differently to allow one of the binding jaws to be moved in the longitudinal direction of the ski. List of reference numbers
