Abstract

Release mechanism for at least one holding device for a shoe binding for a sliding board, especially a ski, is electronically controlled and operates the holding device depending on the forces and/or torque acting on the leg of the user. The release mechanism has a spring-loaded blocking device which interacts with an anchor held by a magnet (6) whose release releases the holding device. The anchor is an anchor plate (9) arranged so that the holding force of the magnet acts at least in the longitudinal direction of the ski. The blocking device released when the anchor is released has components which can be moved in the longitudinal direction of the ski. An Independent claim is also included for a binding comprising the above release mechanism. Preferred Features: The anchor plate is connected to the blocking device via a flexible connecting element, especially a cable (11).

Description

The invention relates to a trigger mechanism connectable with a shoe holding bond for a sliding board, which trigger mechanism electronic is controlled and in response to forces acting on the leg of the user and / or moments a holding means for releasing the shoe actuated and a spring-loaded blocking device, which with one of a magnet held anchor whose release causes the release of the holding means, is actively connected. The invention further relates to a binding for a gliding board, in particular a ski binding, with such a triggering mechanism.

Such a triggering mechanism and binding for a gliding board are known for example from DE 39 32 892 A. Subject of this Document is a safety ski binding with an electronic circuit that the forces and / or moments acting on the skier's leg detected at least one transducer and upon reaching a predetermined Threshold excited or de-energized an electromagnet whose anchor the Locking of a sole holder of the safety ski binding triggers. The sole holder is loaded by a spring towards its open position and is through held the locking device in its closed position. It is one independent of the electronic circuit mechanical, pneumatic or Hydraulic device provided, on the one hand by the sole holder or a thus affected in operative connection part at least over a measuring path and on the other hand has a separating member which is a shock absorber is downstream and the armature of the electromagnet or part of the Locking device in the sense of releasing the locking of the sole holder can influence. This is to ensure that in the case of defects, for example, in case of power failure, one at least approximately the same Tripping characteristic remains. The of the electronic circuit independent mechanical, pneumatic or hydraulic device therefore poses In any case, a slightly delayed mechanical release safely.

From EP 0 968 742 A is a ski binding part for a safety ski binding known, which acts against a spring force triggering mechanism for a used ski boot and which has a transverse axis is pivotable or slidably mounted in the ski longitudinal direction and in addition held by a detent mechanism independent of the trigger mechanism is. This locking mechanism has a at the bottom of an intermediate plate in Direction Ski pointing locking part on, with a recess for recording a hook-like bolt is provided. The latch is on the base plate at one pivotally arranged transversely to the ski longitudinal axis and can by means of an electromagnet in the case of release of the locking recess on the locking part be panned.

Problematic in the previously known solutions for electronic However, tripping mechanisms are less power failures or defects of the Circuit or the magnet, but the high power consumption and the Susceptibility of the mechanisms to beatings, in this regard is in particular the with magnets interacting with the magnet.

This is where the invention begins, whose task is to provide a Trigger mechanism for a binding to perform such that its operation requires a much lower energy consumption than that of the known Trigger mechanisms, and that he is largely resistant to impact and thus False triggering can actually be avoided.

We solved the task according to the invention in that the anchor as Anchor plate is executed, on which the holding force of the magnet in the longitudinal direction of the sliding board, and that released in the case of release of the anchor Blocking device in the longitudinal direction of the sliding board and in planes parallel to Sliding board level has movable components.

The anchor plate and the blocking device are therefore impact-resistant arranged and stored. The movements provided in the longitudinal direction of this Components or acting in the longitudinal direction of the holding force of the magnet requires very little electrical energy.

In connection with the mounting of the anchor plate, it is particularly favorable if these are at least substantially perpendicular to the Gleitbrettoberseite is arranged and on a sliding in Gleitbrettlängsrichtung slide the Blocking device is suspended. This is not just a forceful special favorable arrangement but it is ensured in this way that the Anchor plate over the magnet can center automatically.

In this context, it is advantageous if the anchor plate with the Blocking device via a flexible connecting element, a rope or the like, is connected.

Protection against pollution, snow and ice offers according to another Feature of the invention, the accommodation of the blocking device, the anchor plate and the magnet in a flat housing.

The blocking device is in a simple and convenient manner via a Actuator with the binding connection element, which for example a binding terminal plate is connected.

Of particular importance is that the components of the blocking device deliberately functional and functional and are doing as little as possible Space, in particular considered perpendicular to the surface, claim. this will ensured by a number of inventive features. For example the actuating device has a binding connection element with a Centering connecting actuating rod. The centering device is with a locking element, such as a locking pin provided, which of the Housing pivotally mounted scissor arms is releasably held. In the tensioned position of the trigger mechanism while the scissor arms are on Slide held or locked so that when triggered at a shift of the slider, the scissor arms released from their latching on the slide be so that the engagement of the scissor arms on the locking element of Centering device is released.

In addition, both the Binding element as well as the slide can be acted upon by springs.

The individual components of the blocking device are now designed and act together in such a way that after tripping by an actuation of the Binding connection element a return of the components of the Blocking device and the anchor plate is possible in their initial positions. According to a related embodiment of the invention it is provided that the centering centering has, with centering pins or like the scissor arms cooperate in such a way that the scissor arms in to return to their initial position on the blocking element and on the slide. On the Slider can return at least one anchor plate to its original position Be operated driver.

In a preferred embodiment of the invention that is Binding connection element for releasing the or the holding means of the shoe in Ski longitudinal direction displaceable. Alternatively, it may be provided that the Binding connection element for releasing the holding means pivot and / or is tiltable.

The invention further relates to a bond with an inventively executed Trigger mechanism. Preference is given to a placement of the Triggering mechanism within a binding plate, base plate or the like, which is connected at least via a bearing part with the sliding board.

For detecting the forces acting on the leg of the skier and / or Moments, at least one force measuring system is provided, which in particular housed in one of the bearing parts.

The holding means for the shoe can now in particular be carried out conventionally Skibindungsteile be a mechanically triggering safety ski binding on at least one binding plate or the like are arranged.

However, embodiments of bindings according to the invention are also possible which the holding means for the shoe on this releasably lockable hook or are the like. Of the holding means, be it mechanically triggering Skibindungsteile or other holding devices is at least one such arranged that it cooperates with a binding connection element, the can be actuated by means of the trigger mechanism according to the invention.

Fig. 1 shows one of the basic possibilities of execution or arrangement a ski binding designed according to the invention. On a ski 3 is under Intermediate arrangement of two bearing parts 2 a binding plate 1 is arranged. at the embodiment shown is the the front end of the Binding plate 1 associated bearing part 2, the binding plate 1 in Skilängs- and Skiquerrichtung fixing part. Within this bearing part 2 is a Force measuring system 4 housed which between the plate 1 and the ski. 3 occurring and transmitted from the foot of the skier on the ski 3 forces, at least in the horizontal and vertical directions, in particular in arbitrary Directions, measures. The force measuring system 4 accommodated in the front bearing part 2 is not the subject of the invention and can therefore be applied to any suitable Be executed manner. Likewise not the subject of the invention is the Force measuring system 4 downstream evaluation electronics, not shown, which can be accommodated in the binding plate 1 and about which in dependence from the measured forces and stored comparison values the Decision is made whether the further described below Trigger mechanism is actuated. One or more voltage source (s), such as Rechargeable batteries or batteries, both supply and supply the transmitter as also the trigger mechanism. The voltage source (s) may or may also be housed in the binding plate 1.

The rear bearing part 2 provides the second connection of the binding plate 1 with the ski 3 ago and is executed in the embodiment shown so that a limited longitudinal movement of the binding plate 1 in the ski longitudinal direction opposite the ski 3 is possible. The indicated in the figure shoe 1 a is at the embodiment shown by two conventionally designed ski binding parts, a front ski binding part 5a and a rear ski binding part 5b held the binding plate 1. The two ski binding parts 5a, 5b are also not objects of this invention and can in a conventional manner executed, in particular ensuring a safety release Be ski binding parts.

According to another variant, not shown, instead of the two Skibindungsteile 5a, 5b, for example, laterally mounted on the binding plate 1 Pairs of hooks are provided on the side of the shoe or the shoe sole overlap projecting pins to hold the shoe. The hooks are like that arranged or stored that they have an arbitrary release of the shoe guarantee. In another embodiment, also not shown, the Ski boot front and rear overarching holding devices without additional mechanical release mechanisms are provided. Both at one Version with conventional ski binding parts as well as other Holding devices, hooks or the like, is provided that at least one the two ski binding parts or one of the holding devices via the means of mentioned evaluation electronics triggered release mechanism release of the shoe is guaranteed. The release of a held by the bond Schuhes can be done, for example, that an actuation of the Trigger mechanism a limited displacement of the front ski binding part 5a causes forward in the ski longitudinal direction. In a version with hook pairs or other holding devices, the trigger mechanism Pivoting at least one of the holding means for releasing the shoe or also a sliding movement of at least one holding device in the longitudinal direction of the ski, away from the second, effect.

For the mentioned sliding movement of the front ski binding part 5a in Ski longitudinal direction for releasing the ski boot 1a, as in particular from FIG. 2 it can be seen, a binding connection plate 8 are provided, which relative to a housing 7 which is accommodated in the binding plate 1 and otherwise for incorporating the components of the detail described below Trigger mechanism is provided, is movable in the ski longitudinal direction. The Binding connection plate 8 is via an actuating rod 15 with more Components of the trigger mechanism is operatively connected and is of two biased compression springs 16 acted upon. On the binding terminal plate 8 the front Skindungsteil 5a, for example by means of screws, attached. The Bonding terminal plate 8 is designed to be opposite and inside the binding plate 1 and in the longitudinal direction thereof largely free of friction and is slidably movable.

The one end of the actuating rod 15, by means of which, by the springs 16 supports, the slidable displacement of the same in the longitudinal direction in Tripping case takes place, is firmly connected to the binding connection plate 8, the second End of the actuating rod 15 is sufficient, as already mentioned, in the interior of the Housing 7 and here, as it shows, for example, Fig. 2, via one or a plurality of bolts 17 with an extending in the ski longitudinal attachment portion 18b a centering fork 18 firmly connected. In extension of the actuating rod 15 is the centering fork 18 is provided centrally with a locking pin 19, of the Underside of the centering fork 18 protrudes. This can be seen in FIGS. 5 and 6. The Centering fork 18 has two lateral fork arms 18a, which are in ski or Housing longitudinal direction and the free ends on the outside each have a short End face 18c and thereafter and, considered for both arms 18a, V-shaped converging, each having an actuating slope 18d, on whose Function will be discussed later. In addition to the attachment part 18a are symmetrical to Longitudinal axis of the housing 7 two scissor arms 21 to another bolt 20, the are fixed to the housing, pivotally mounted. The two in the housing in Longitudinally extending scissor arms 21 are located below the Fork arms 18a. As can be seen in particular from Fig. 5, where the better overview half only a scissor arm 21 is located, each scissor arm 21 has a pointing in the direction of the housing longitudinal locking block 22 with a oblique blocking surface 22a, which with tensioned trigger mechanism each engages behind the locking pin 19 of the centering fork 18 and thereby the Actuating rod 15 and the binding connection plate 8 in its rest or Starting position stops.

Further Sperransätze 23, which faces away from the bearing pin 20 ends of the Scissor arms 21 are provided on the outside, causing the two Scissor arms 21 in a mutually depressed position in a recess 24th are held on the underside of a slider 10. The recess 24 is formed between two lugs 25 on the underside of the slider 10, wherein the Embodiment of the intervening scissor arms ends and the approaches 25 so is taken that at a certain displacement of the slider 10 in the direction the scissor arms 21 free the Sperransätze 23 of the recess 24 and the Scissor arms 21, on the top of the lugs 25 sliding apart can. The interaction of slider 10 and scissor arms 21 is still explained in more detail below.

For example, as shown in FIG. 2 and FIG. 3, on the top side of FIG Scissor arms 21 and those facing away from the bearing pin 20 End regions centering pins 26 arranged on the function also something will be discussed later.

A core of the trigger mechanism is a slide 10 holding or with this cooperating anchor plate 9. The anchor plate 9 is in the unactuated (cocked) position of the triggering mechanism of a magnet 6, which may be a permanent or electromagnet, but in particular a Permanent magnet is, and which on the binding connection plate. 8 remote end portion of the housing 7 is firmly installed in this held.

The anchor plate 9 is connected to the slider 10 in connection. Fig. 4 shows a Possibility of the kind of connection of these two parts being of importance that the anchor plate 9 is not fixedly connected to the slider 10, but quasi at this "suspended" or stored. This can be a connecting rod or a connecting cable 11 may be provided, which at its one end on Slider 10 is attached or attached centrally and at its second end a carries hemispherical executed calotte 12, which in a particular opposite executed hemispherical recess 9a of the anchor plate 9 is located. In this way, a certain mobility of the anchor plate 9 against the Magnets 6 and also the slider 10 ensures, so that the anchor plate. 9 can center on the magnet 6 itself. The magnet 6 can thus relative to the anchor plate 9 develop its maximum holding power.

On the slider 10 are facing towards the anchor plate 9 and with this at tensioned position of the trigger mechanism in contact carrier 10a arranged, which extend in the housing or ski longitudinal direction, and in the Housing 7 are preferably also guided. Between the anchor plate 9 and the Slide 10 protrude from the housing 7 support lugs 27 (see Fig. 2 and 3) in the Housing interior, the receptacles or abutment for the one ends of two form further compression springs 14 which act on the slider 10. In the in Fig. 2 and 5 shown retracted tension are the compression springs 14th preloaded and thus compressed.

In the unactuated, tense situation of the trigger mechanism is the Anchor plate 9 held by the magnet 6, the slider 10 is over the Sperransätze 23 of the scissors arms 21 held, the scissor arms 21 hold over their Sperransätze 22 the centering fork 18 and thus on the actuating rod 15th the binding connection plate 8 in its rest position.

Will now on the taking place in the transmitter evaluation of the forces found that act on the foot of the skier forces acting on a release require or suggest for safety reasons, the anchor plate 9 through Excitement or de-energizing of the magnet 6 is released. This will push the Springs 14, the slider 10 in the direction binding pad 8, the Scissor arms 21 and their Sperransätze 23 are released from the recess 24 and can thus move apart or open. By opening the two Scissor arms 21, the locking pin 19 of the centering fork 18 is released and the with the centering fork 18 connected actuating rod 15 can under the effect the compression springs 16 and the transmitted from the shoe forces the Move binding connection plate 8 forward. This is the shoe of the Skier from the two ski binding parts 5a, 5b free.

The return of the release mechanism to the starting position is on a very easy way possible. For this purpose, only the front ski binding part 5a in Direction of the rear ski binding part 5 b pushed, causing the Operating slopes 18 d of the ends of the fork arms 18 a of the centering fork 18 the Detecting centering pins 26 on the tops of the two scissor arms 21 so that be pressed over the slopes 18 d, the two scissor arms 21. During this sequence of movements, the barriers 22 pass back behind In this case, the slider 10 against the force of the springs 14 shifted in the direction of the magnet 6. Detect during this sliding movement the drivers 10 a, the anchor plate 9, which approaches the magnet 6 again and due to its suspension or storage relative to the magnet 6 self-centered. During this movement come over the again compressed scissor arms 21 whose Sperransätze 23 back into their latched position in the recess 24. This is the original starting position restored. The interpretation of the components and their Spaces of movement allow a certain "Überweg", in any case to ensure a "docking" of the anchor plate 9 on the magnet 6.

The triggering mechanism according to the invention is made of various types Reasons particularly advantageous. Guide the components of the release mechanism mainly movements parallel to the scrub and especially in Skilängsrichtung out, so they are very shock resistant stored. The Focusing on movements in the skiebene has the consequence that the Components of the trigger mechanism can be made very flat, so they take up very little space. Movements of the ingredients in Ski longitudinal direction also have the great advantage, only a very small To require energy. Thus, a triggering requires a solution of Anchor plate 9 from the magnet 6, low energy. Also the storage and arrangement the anchor plate 9 is very shock resistant, especially by their vertical arrangement relative to the ski upper side. In addition to the low Energy consumption also ensures a triggering mechanism according to the invention a very quick release, the movements initiated will be prompt on the Transfer binding plate 8 transferred.

In the illustrated embodiment, a trigger by the Activation mechanism according to the invention additionally provided to the Users of the ski binding then offer increased security when the mechanically working ski binding parts are not able to provide a necessary To ensure triggering.

The measurement bars or the like provided for force measurement can be so be arranged and executed so that they measure forces in any direction can. In this case, an embodiment may be provided in which in all provided between the binding plate 1 and the ski 3 bearing parts Force measuring systems are housed. But it is also conceivable that Provide force measuring device elsewhere, for example, between the Ski boot and ski binding plate or ski boot and foot of Skier.

According to another, not shown embodiment, the binding plate only be connected in the middle of a single bearing part with the ski, in which Bearing part of the force measuring system is housed. It is also possible, each Ski binding part or each front and rear holding device via separate Base plates or bearing parts to be connected to the ski and in at least one These parts to arrange a force measuring system. Any, especially limited, slidable arrangements of the base plates or binding plates are of course possible. There are also possible designs in which the or the force measuring system (s) directly between the holding device or the Binding part and the ski are arranged.

Furthermore, as already mentioned, it is not necessary that the Release mechanism caused movement a longitudinal movement of a component, in the embodiment shown, this is the binding connection plate 8, result Has. The resulting movement can of course also a rotary or Be pivotal movement, for example, to a shoe engaging hooks or the like to solve. In addition, it is possible to do the mechanism like that execute, that or additionally, the rear ski binding part 5b is moved and / or rear provided hooks are actuated. Of course, the trigger mechanism is also suitable for bindings or holding devices of snowboards or other sliding boards to operate.
