Abstract

An electronic circuit of a safety ski-binding detects at least the forces and/or torques acting on the leg of the skier by means of at least one transducer. On reaching a predetermined threshold, the circuit energises or de-energises an electromagnet whose armature releases the lock of a sole holder which is preferably stressed by a spring in the direction of its opened position and is held in its closed position by means of a locking device. The circuit and the magnet are supplied by a battery. In order to ensure a reliable release with an essentially constant release characteristic, even in the case of a power failure, a mechanical, pneumatic and/or hydraulic device (8) is provided, which is independent of the electronic circuit, on the one hand is influenced by the sole holder or by a part which is effectively connected thereto, at least over a measurement path, and on the other hand has a separating element (9) which is connected downstream from a shock absorber (11, 13, 24) and can influence the armature (2) of the electromagnet (1), or a part (3) of the locking device, in the sense of releasing the lock of the sole holder. <IMAGE>

Description

Die Erfindung bezieht sich auf Sicherheits-Skibindungen mit einer elektronischen Schaltung nach den Merkmalen des Oberbegriffs des Anspruchs 1.The invention relates to safety ski bindings with an electronic circuit according to the features of the preamble of claim 1.

Derartige Sicherheits-Skibindungen haben zwar bisher über Einzelstücke hinaus keinen Eingang in die Praxis gefunden, gehören aber seit langem zum papierenen Stand der Technik. So sei beispielsweise auf die DE 2737535 A1, DE 2938756 A1 und DE 3017841 C2 verwiesen.Such safety ski bindings have so far not found their way into practice beyond individual pieces, but have long been part of the paper state of the art. For example, reference is made to DE 2737535 A1, DE 2938756 A1 and DE 3017841 C2.

Problematisch ist bei allen bekannten Ausführungen die Sicherstellung einer Auslösung im Gefahrenfall auch dann, wenn ein Stromausfall erfolgt oder ein Defekt in der Schaltung oder im Magneten auftritt.The problem with all known designs is to ensure triggering in the event of danger even if there is a power failure or a defect in the circuit or in the magnet occurs.

Bei der Ausführung nach ... 535 wird mit Scherstiften ge­arbeitet, die den Sohlenhalter tragen. Mit dem Ab­reißen der Scherstifte im Gefahrenfall kommt der Sohlenhalter frei und gibt seinerseits den Skischuh aus seiner Bindung am Ski frei. Ein dann notwendiges Austauschen der Scherstifte und Wiederbefestigen des Sohlenhalters auf der Piste ist einem Skiläufer nicht zuzumuten.The version according to ... 535 works with shear pins that support the sole holder. When the shear pins are torn off in the event of danger, the sole holder is released and in turn releases the ski boot from its binding on the ski. A then necessary replacement of the shear pins and reattaching the sole holder on the slopes is a skier unreasonable.

Die Ausführung nach ... 756 sieht in der elektronischen Logik ein Fehlerkontrollsystem vor, das bei Ausfall der Elektronik eine Umschaltung auf eine rein mechanische Auslösefunktion der Sicherheits-Skibindung bewirkt. Hierdurch ist die elektronische Schaltung mindestens durch einen zusätzlichen Schaltkreis zu erweiteren, um Fehler zu erfassen und zu melden.The version according to ... 756 provides for an error control system in the electronic logic which, if the electronics fail, switches over to a purely mechanical release function of the safety ski binding. As a result, the electronic circuit must be expanded at least by an additional circuit in order to detect and report errors.

In der Sicherheits-Skiibndung nach ... 841 ist ebenfalls ein Umschaltmechanismus vorgesehen, der bei Ausfall einer elektrischen Ansteuerung das Auslösesystem auf ein rein mechanisches, pneumatisches bzw. hydraulisches Notauslösesystem umschaltet.A safety mechanism is also provided in the safety ski binding according to ... 841, which switches the release system to a purely mechanical, pneumatic or hydraulic emergency release system in the event of an electrical control failure.

Gegenüber der Ausführung nach ... 535 weisen die anderen zwar den Vorteil auf, daß sie für den Fall eines Defektes in der Schaltung oder des Magneten oder bei Stromausfall wie bisher übliche Sicherheits-Skibindungen arbeiten, doch sind sie so konzipiert, daß eine Fehlermeldung an einen Umschaltmechanismus notwendig ist.Compared to the version according to ... 535, the others have the advantage that they work in the event of a defect in the circuit or the magnet or in the event of a power failure as usual safety ski bindings, but they are designed so that an error message a switching mechanism is necessary.

Einmal dieses zu vermeiden und zum anderen auch im Falle von erwähnten Defekten bzw. bei Stromausfall eine wenig­stens annähernd gleiche Auslösecharakteristik zu behalten, liegt der Erfindung als Aufgabe zugrunde.To avoid this, on the one hand, and to maintain an at least approximately the same tripping characteristic in the event of defects mentioned or in the event of a power failure, the invention is based on the object.

Gelöst ist diese Aufgabe erfindungsgemäß durch das kennzeichnende Merkmal des Anspruchs 1. Die erfindungs­gemäß vorgeshene Einrichtung macht einen Umschaltmechanismus entbehrlich, da das Trennglied der Einrichtung mit aus­reichender jedoch in Bezug auf das Verletzungsrisiko des Skiläufers zulässiger Verzögerung in Funktion tritt.This object is achieved according to the invention by the characterizing feature of claim 1. The device provided according to the invention makes a switching mechanism unnecessary, since the separating element of the device comes into operation with a sufficient delay, however, which is permissible in relation to the risk of injury to the skier.

Eine zweckmäßige Ausführung der Erfindung umfaßt die Merkmale des Anspruchs 2. Durch eine ausreichende Bewegung des Zylinders wird der Vorgang des erfindungsgemäßens Lösens bewirkt.An expedient embodiment of the invention comprises the features of claim 2. The process of releasing according to the invention is effected by sufficient movement of the cylinder.

Vorzugsweise umfassen die Öffnungen in Kolben eine Drossel und ein Rückschlagventil für die erste Zylinderkammer. Hierdurch wird in bekannter Weise eine unverzögerte Rückstellung des Zylinders erreicht. Weiter kann der zylinderfeste Hohlraum sich zu seinem freien Ende hin verjüngen und das Trennglied bilden. In diesem Fall läßt sich die Einrichtung so anordnen, daß das Trennglied unmittelbar den Anker des Elektromagneten beeinflussen kann.The openings in pistons preferably comprise a throttle and a check valve for the first cylinder chamber. As a result, an instantaneous reset of the cylinder is achieved in a known manner. Furthermore, the cylinder-fixed cavity can taper towards its free end and form the separating member. In this case, the device can be arranged so that the isolating element can directly influence the armature of the electromagnet.

Im folgenden ist die Erfindung anhand eines Ausführungsbei­spiels näher beschrieben.The invention is described in more detail below using an exemplary embodiment.

Die einzige Figur der Zeichnung zeigt schematisch und teil­weise im Schnitt die erfindungsgemäße Einrichtung in Zuordnung zu einer Verriegelungseinrichtung eines Sohlen­halters.The single figure of the drawing shows schematically and partly in section the device according to the invention in association with a locking device of a sole holder.

Die Sicherheits-Skibindung, die zum Halten eines Skischuhs in beliebiger und bekannter Weise ausgebildet sein kann, ist nur soweit dargestellt, wie es die erfindungswesentlichen Teile erfordern. Sie besitzt eine elektronische Schaltung, die wenigstens die auf das Bein des Skiläufers einwirkende Kräfte und/oder Momente über entsprechende Meßwege durch mindestens einen Wandler erfaßt und bei Erreichen eines vorgegebenen Schwellenwertes einen Elektromagneten 1, einen sogenannten Remanenzmagneten, erregt oder entregt, dessen Anker 2 die durch einen Winkelhebel 3 dargestellte Verriegelung eines Sohlenhalters löst. Die Achse 4 des Winkelhebels und die Halteplatte 5 des Elektromagneten sind im Gebrauchszustand skifest gehaltene Teile der Bindung. Der Anker 2 des Elektromagneten ist als Klappanker ausgebildet und steht unter dem Einfluß einer ihn im Öffnungssinne belastenden Schraubenzugfeder 6. Der Winkel­hebel 3 ist von einer nicht dargestellten schwachen Haltefeder in Bezug auf die Darstellung im Uhrzeigersinn belastet und in Anlage an einem Anschlag 7 gehalten, der im vorliegenden Fall von einer zapfenförmigen Verlängerung des Weicheisenkerns des Elektromagneten 1 gebildet ist. Er dient gleichzeitig auch als Führung für den Klappanker 2.The safety ski binding, which can be designed to hold a ski boot in any known manner, is only shown to the extent required by the parts essential to the invention. It has an electronic circuit that detects at least the forces and / or moments acting on the skier's leg via corresponding measuring paths by at least one transducer and, when a predetermined threshold value is reached, excites or de-energizes an electromagnet 1, a so-called remanence magnet, the armature 2 of which lock of a sole holder shown by an angle lever 3 releases. The axis 4 of the angle lever and the holding plate 5 of the electromagnet are parts of the binding that are held in a ski-tight state in use. The armature 2 of the electromagnet is designed as a hinged armature and is under the influence of a helical tension spring 6 which loads it in the opening direction in the present case is formed by a peg-shaped extension of the soft iron core of the electromagnet 1. It also serves as a guide for the hinged anchor 2.

Greift am Bein des Skiläufers eine Kraft oder ein Moment an, die bzw. das dem jeweils vorgegebenen Schwellenwert entspricht, geht durch die Spule des Elektromagneten aufgrund eines in der elektronischen Schaltung erzeugten Impulses ein Stromstoß, der die magnetische Haltekraft für den Anker wenigstens soweit aufhebt, daß der Anker unter dem Einfluß der Schraubenzugfeder 6 gegen den Winkelhebel 3 schlagen und ihn entgegen der Kraft seiner Haltefeder um die Achse 4 schwenken kann, Was in nicht dargestellter Weise mittelbar oder unmittelbar zum Lösen der Verriegelung des Sohlenhalters führt, so daß sich der Skischuh aus der Bindung und damit vom Ski losen kann. Wegen konstruktiver Einzelheiten sei beispielsweise auf die DE 3132465 A1 und DE 3146318 C2 verwiesen.If a force or a moment acts on the skier's leg that corresponds to the respectively predefined threshold value, a current impulse passes through the coil of the electromagnet due to a pulse generated in the electronic circuit, which cancels the magnetic holding force for the anchor at least to the extent that the anchor hit under the influence of the coil spring 6 against the angle lever 3 and it can pivot against the force of its retaining spring about the axis 4, which leads, in a manner not shown, directly or indirectly to releasing the locking of the sole holder, so that the ski boot is off can loosen the binding and thus the ski. For structural details, reference is made, for example, to DE 3132465 A1 and DE 3146318 C2.

Gemäß der vorliegenden Erfindung ist eine in ihrer Gesamtheit mit 8 bezeichnete Einrichtung vorgesehen, die einerseits vom nicht dargestellten Sohlenhalter oder einem damit in Wirkverbindung stehenden Teil zumindest über den Meßweg beeinflußt wird. Die Einrichtung weist ein Trenn­glied 9 auf, das im vorliegenden Fall den Winkelhebel 3 im Sinne des Lösens der Verriegelung des Sohlenhalters beein­flussen kann.According to the present invention, a device designated 8 in its entirety is provided, which is influenced on the one hand by the sole holder, not shown, or a part that is operatively connected to it, at least via the measuring path. The device has a separating element 9, which in the present case can influence the angle lever 3 in the sense of releasing the locking of the sole holder.

Entsprechend der Halteplatte 5 für den Elektromagneten 1 ist eine Halteplatte 10 für die Einrichtung 8 vorgesehen. Diese Einrichtung umfaßt einen Stoßdampfer mit einem Kolben 11, der über seine Kolbenstange 12 fest mit der Halteplatte 10 verbunden ist. Auf dem Kolben und der Kolbenstange ist ein Zylinder 13 verschiebbar gelagert. Sein Innenraum ist durch den Kolben in eine erste (14) und eine zweite Zylinderkammer 15 für ein flüssiges oder gasförmiges Medium unterteilt. Beide Kammern sind durch eine Drossel 16 und durch ein Ruckschlagventil 17 im Kolben 11 miteinaner verbunden.Corresponding to the holding plate 5 for the electromagnet 1, a holding plate 10 is provided for the device 8. This device comprises a shock absorber with a piston 11 which is fixedly connected to the holding plate 10 via its piston rod 12. A cylinder 13 is slidably mounted on the piston and the piston rod. Its interior is divided by the piston into a first (14) and a second cylinder chamber 15 for a liquid or gaseous medium. Both chambers are connected to each other by a throttle 16 and a check valve 17 in the piston 11.

Der Kolben 11 und seine Kolbenstange 12 sind axial durchbohrt und nehmen einen Stößel 18 auf, der in Bezug auf die Darstellung rechts von der Halteplatte 10 in nicht gezeichneter beliebiger geeigneter Weise direkt oder indirekt mit dem Sohlenhalter verbunden ist. Ebenfalls mit dem Stößel verbunden befindet sich in der Zylinderkammer 15 ein Federteller 19. Dieser ist auf einen Abgesetzten Teil 20 des Stößels aufgesteckt, der sich durch die Zylinderstirnwand 21 in einen zylinderfesten Hohlraum 22 erstreckt und am freien Ende einen Flansch 23 trägt, dessen Rand die Zylinderstirnwand 21 hintergreift. An der Zylinderstirnwand stützt sich eine Dämpfungsfeder 24 ab, die auf den Federteller 19 des Stößels 18 wirkt.The piston 11 and its piston rod 12 are drilled axially and receive a plunger 18 which is connected directly or indirectly to the sole holder in any suitable manner, not shown, with respect to the illustration to the right of the holding plate 10. Also connected to the tappet is a spring plate 19 in the cylinder chamber 15. This is attached to a stepped part 20 of the tappet, which extends through the cylinder end wall 21 into a cylinder-fixed cavity 22 and carries a flange 23 at the free end, the edge of which carries the Cylinder end wall 21 engages behind. A damping spring 24 is supported on the cylinder end wall and acts on the spring plate 19 of the plunger 18.

Im vorliegenden Fall ist der zylinderfeste Hohlraum 22 durch das Innere des Trenngliedes 9 gebildet, das sich zu seinem freien Ende hin verjüngt. Während das Trennglied im vorliegenden Beispiel zum Zusammenwirken mit dem Winkelhebel 3 vorgesehen ist, kann es ebensogut mit einem geeigneten anderen Teil, beispielsweise unmittelbar mit dem Klappanker 2, im Sinne des Lösens der Verriegelung des Sohlenhalters zusammenwirken.In the present case, the cylinder-fixed cavity 22 is formed by the interior of the separating member 9, which tapers towards its free end. While the separator in the present example is intended to interact with the angle lever 3, it can just as well interact with a suitable other part, for example directly with the hinged anchor 2, in the sense of releasing the locking of the sole holder.

Wenn der Sohlenhalter im Bereich seiner Meßwege bewegt wird, wird diese Bewegung durch den Stößel 18 auf die Einrichtung 8 übertragen. Stoßartige für das Bein des Skiläufers unge­fährliche Kräfte werden dadurch gedämpft, daß sich der Stößel 18 im Zylinder 13 entgegen der Kraft der Dämpfungs­feder 24 bewegt. Der Zylinder 13 kann in diesem Fall der Stößelbewegung nicht folgen, da der Kolben 11 wegen der Drossel 16 und des Rückschlagventils 17 keinen schnellen Übertritt des entsprechenden Mediums aus der Zylinderkammer 14 in die Zylinderkammer 15 zuläßt. Erst bei einer quasi statischen Belastung von entsprechender Größe erfolgt die Verschiebung des Zylinders 13 mit dem Stößel 18, was schließlich zur Betätigung des Winkelhebels 3 durch das Trennglied 9 führt. Eine anschließende schnelle Rückstellung des Zylinders 13 ist durch das Rückschlagventil 17 ermöglicht. Diese Rückstellung kann in beliebiger und gewünschter Weise durch geeignete Bindungsteile oder eine besondere Feder erfolgen.If the sole holder is moved in the area of its measuring paths, this movement is transmitted to the device 8 by the plunger 18. Forces that are harmless to the skier's leg are damped by the fact that the plunger 18 moves in the cylinder 13 against the force of the damping spring 24. In this case, the cylinder 13 cannot follow the tappet movement, since the piston 11, because of the throttle 16 and the check valve 17, does not allow the corresponding medium to pass quickly from the cylinder chamber 14 into the cylinder chamber 15. Only when there is a quasi-static load of an appropriate size does the cylinder 13 move with the tappet 18, which finally leads to the actuation of the angle lever 3 by the separating member 9. A subsequent quick resetting of the cylinder 13 is made possible by the check valve 17. This provision can be made in any desired manner using suitable binding parts or a special spring.

Durch die im zulässigen Maße verzögerte mechanische Auslösung ist es nicht notwendig, daß hierbei mit gegebenen­falls unzulässig erhöhten Auslösewerten gearbeitet werden muß. Im Gegensatz zum Stand der Technik ist die erfindungs­gemäße Einrichtung ständig funktionsbereit. Sie bildet also kein "Notauslösesystem", das erst durch manuelle oder auto­matische Umschaltung in Funktion gesetzt wird, wenn ein Stromausfall erfolgt oder ein Defekt in der Schaltung oder im Magneten auftritt.Due to the delayed mechanical triggering, it is not necessary to work with trigger values that may be inadmissibly higher. In contrast to the prior art, the device according to the invention is always ready for operation. It therefore does not form an "emergency release system" that is only activated by manual or automatic switchover if there is a power failure or a defect in the circuit or in the magnet occurs.
