Abstract

The safety ski binding has a first and a second jaw for holding a ski boot on a ski. The first jaw has a contactor which is actuated when predetermined forces are reached, which forces are transmitted from the ski boot to the first jaw in at least two planes located perpendicular to one another. To achieve a design which is simple in construction and reliable in function, it is proposed that the first jaw has a sole holder (6) which is supported on the side away from the ski boot on a bolt (13), which is parallel to a transverse axle (5) and is held on the base part (2) fixed to the ski, in such a way that it can swivel away from the ski boot by a small amount from its normal position counter to spring force and that it (6) is displaceable axially by a small amount from its normal position towards both sides counter to spring force on the transverse axle (5). The bolt (13) bears a control lever (21), which actuates the contactor and for which three carriers are provided so that the control lever (21) can follow both an axial movement and a rotary movement of the sole holder (6). <IMAGE>

Description

Die Erfindung bezieht sich auf einen Meßbacken einer Sicherheits-Skibindungen gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a measuring jaw of a safety ski binding according to the preamble of claim 1.

Ein derartiger Meßbacken ist beispielsweise aus der EP 0091574 B1 bekannt. Dieser Meßbacken ist mit zwei Sohlenhaltern ausgerüstet, die die Sohle des Skischuhes jeweils von oben und von einer Seite umfassen und auf einem gemeinsamen vertikalen Bolzen geringfügig verschwenkbar gelagert sind. Ein diesen Bolzen tragender Lagerkörper ist seinerseits um eine horizontale Querachse geringfügig verschwenkbar, die in einem skifest zu montierenden Gehäuse gelagert ist. Als Kontaktgeber sind in dem Gehäuse drei Druckmessdosen eingebaut. Diese Konstruktion gestattet ein Erfassen der im Bereich des Messbackens auftretenden Kräfte. Diese zum papierenen Stand der Technik gehörende Sicherheits-Skibindung weist zwar gegenüber weiter bekannten Sicherheits-Skibindungen gewisse Vorteile auf, hat jedoch bisher keinen Eingang in die Praxis gefunden. Dieses ist wohl in dem konstruktiven Aufwand begründet, den der Meßbacken erfordert.Such a measuring jaw is known for example from EP 0091574 B1. This measuring jaw is equipped with two sole holders, each of which encompasses the sole of the ski boot from above and from one side and is mounted so that it can be pivoted slightly on a common vertical bolt. A bearing body carrying this bolt can in turn be pivoted slightly about a horizontal transverse axis which is mounted in a housing to be mounted in a ski-tight manner. Three pressure transducers are built into the housing as contactors. This construction allows the forces occurring in the area of the measuring jaw to be recorded. This safety ski binding, which belongs to the state of the art on paper, has certain advantages over more well-known safety ski bindings, but has not yet been used in practice. This is probably due to the design effort that the measuring jaw requires.

Es ist darum Zweck der vorliegenden Erfindung, einen gattungsgemäßen Meßbacken so auszubilden und zu gestalten, daß sie weniger aufwendig und damit auch einfacher und billiger herstellbar und nicht so störungsempfindlich ist.It is therefore the purpose of the present invention to design and design a generic measuring jaw in such a way that it is less complex and thus also easier and cheaper to manufacture and is not as sensitive to faults.

Dieses ist erfindungsgemäß durch die kennzeichnenden Merkmale des Patentanspruchs 1 erreicht. Somit finden bei der erfindungsgemäßen Konstruktion anstelle von Druckkolben und Druckmessdosen nur mechanische Elemente Verwendung. Dichtungsprobleme und daraus resultierende Schwierigkeiten können also im vorliegenden Fall nicht auftreten.This is achieved according to the invention by the characterizing features of patent claim 1. Thus, only mechanical elements are used in the construction according to the invention instead of pressure pistons and pressure measuring cells. Sealing problems and the resulting difficulties cannot therefore arise in the present case.

In konstruktiver Ausgestaltung der Erfindung kann der Sohlenhalter auf der horizontalen Querachse unter Zwischenschaltung von zwei Büchsen gelagert sein, wobei die Büchsen axial unbeweglich gehalten sind. Auf diese Weise läßt sich der Reibungswiderstand beim Bewegen des Sohlenhalters auf der Querachse äußerst gering halten. Hierbei hat es sich als vorteilhaft erwiesen, daß zwischen den Büchsen auf der Querachse eine Schraubendruckfeder gelagert ist, daß in der Länge des Büchsenabstandes voneinander der Sohlenhalter zylindrisch ausgespart ist und daß sich in der Normalstellung des Sohlenhalters die Schraubendruckfeder beidendig sowohl an der Büchse als auch am Sohlenhalter abstützt. Wenn nach einem weiteren Merkmal der Erfindung in der Normalstellung des Sohlenhalters die Büchsen außenseitig gegenüber diesem um ein geringes Maß vorstehen, ist dem Sohlenhalter auf einfache Weise die Möglichkeit gegeben, auf der Querachse aus seiner Normalstellung heraus sich axial um ein geringes Maß entgegen der Kraft der Feder nach beiden Seiten hin zu verschieben.In a constructive embodiment of the invention, the sole holder can be mounted on the horizontal transverse axis with the interposition of two bushes, the bushes being held axially immovably. In this way, the frictional resistance when moving the sole holder on the transverse axis can be kept extremely low. It has proven to be advantageous that a helical compression spring is mounted between the sleeves on the transverse axis, that the sole holder is cylindrically recessed in the length of the sleeve spacing and that in the normal position of the sole holder, the helical compression spring is attached to both ends of the sleeve and on Sole holder supports. If, according to a further feature of the invention, in the normal position of the sole holder, the bushes protrude on the outside relative to the latter by a small amount, the sole holder is given the possibility in a simple manner to move axially out of its normal position by a small amount against the force of the Move the spring to both sides.

Durch die Merkmale des Patentanspruchs 5 läßt sich eine äußerst kompakte Konstruktion des Sohlenhalters und seiner Lagerung erreichen.Due to the features of claim 5, an extremely compact construction of the sole holder and its storage can be achieved.

Nach einem weiteren Merkmal der Erfindung kann der Sohlenhalter als zweiarmiger Hebel ausgebildet sein, wobei sich der zweite Arm von der horizontalen Querachse nach unten hinerstreckt und in Wirkverbindung mit der Trittplatte steht, die den Ballendruck des Skischuhs aufnimmt.According to a further feature of the invention, the sole holder can be designed as a two-armed lever, whereby the second arm extends downwards from the horizontal transverse axis and is in operative connection with the tread plate, which absorbs the ball pressure of the ski boot.

Eine konstruktive Lösung, den Sohlenhalter am Grundteil aus seiner Normalstellung heraus entgegen Federkraft um ein geringes Maß vom Skischuh weg-schwenken zu können, sieht vor, daß der Bolzen zwei Langlöcher durchsetzt, die in zwei Augen des Sohlenhalters vorgesehen sind, und daß in der Normalstellung des Sohlenhalters die äußeren Enden der Langlöcher unter dem Einfluß einer Schraubendruckfeder in Anlage an dem Bolzen gehalten sind. In diesem Fall hat es sich als vorteilhaft erwiesen, daß der Bolzen gegenüber dem Grundteil axial unbeweglich ist und daß der Sohlenhalter und der Steuerhebel auf dem Bolzen in dessen Längsrichtung verschiebbar sind.A constructive solution, to be able to pivot the sole holder on the base part out of its normal position against spring force by a small amount from the ski boot, provides that the bolt passes through two elongated holes which are provided in two eyes of the sole holder, and that in the normal position the sole holder, the outer ends of the elongated holes are held in contact with the bolt under the influence of a helical compression spring. In this case, it has proven to be advantageous that the bolt is axially immovable relative to the base part and that the sole holder and the control lever are displaceable on the bolt in the longitudinal direction thereof.

Der Sohlenhalter kann zur Aufnahme des Steuerhebels eine Aussparung aufweisen, die mit ihren vertikalen Seitenflächen zwei Mitnehmer für den Steuerhebel bildet. Weiter kann der Steuerhebel zweiarmig ausgebildet sein und der zweite Arm als Anschlag für einen Mitnehmer des Sohlenhalters dienen.The sole holder can have a recess for receiving the control lever, which forms two drivers for the control lever with its vertical side surfaces. Furthermore, the control lever can be designed with two arms and the second arm can serve as a stop for a driver of the sole holder.

Um den ersten Backen über seine Funktion als Meßbacken hinaus auch als unwillkürlich auslösbaren Backen zu benutzen, kann in Weiterbildung der Erfindung der den Sohlenhalter abstützende Bolzen über eine lösbare Sperreinrichtung an dem Grundteil gehalten sein. Hierbei kann die Sperreinrichtung einen Sperriegel aufweisen,der von einem Elektromagneten der elektronischen Schaltung auslösbar ist.In order to use the first jaw beyond its function as a measuring jaw as an involuntarily releasable jaw, in a further development of the invention the bolt supporting the sole holder can be held on the base part via a releasable locking device. Here, the locking device can have a locking bolt that can be triggered by an electromagnet of the electronic circuit.

Hierbei ist nach einem vorteilhaften Konstruktionsvorschlag der Erfindung der Bolzen in einer Druckstange gelagert, die sich auf dem Grundteil längsbeweglich abstützt und durch den Sperriegel in ihrer Normal-Stellung gehalten ist. Dabei kann zwischen dem Abstützende der Druckstange und dem Grundteil ein Kniehebel vorgesehen sein mit parallel zur Querachse verlaufenden Achsen. Der Sperriegel hintergreift dann das Knie des Kniehebels, der unter dem Einfluß einer Rückstellfeder steht.Here, according to an advantageous design proposal of the invention, the bolt is mounted in a push rod which is supported on the base in a longitudinally movable manner and is held in its normal position by the locking bolt. In this case, a toggle lever with axes running parallel to the transverse axis can be provided between the support end of the push rod and the base part. The locking bolt then engages behind the knee of the knee lever, which is under the influence of a return spring.

Als zweckmäßig hat es sich erwiesen, als Sperriegel einen parallel zur Querachse am Grundteil gelagerten Drehriegel vorzusehen.It has proven to be expedient to provide, as a locking bolt, a rotary bolt mounted parallel to the transverse axis on the base part.

In the present case, the jaw according to the invention is designed so that the other jaw can dispense with devices for involuntary triggering in the event of overloading.

Ebenfalls nicht Gegenstand der vorliegenden Erfindung ist die elektronische Schaltung, welche nach Überschreiten vorgegebener Grenzwerte ein Auslösesignal für den Backen abgibt. Diesbezüglich kann ebenfalls auf den Stand der Technik zurückgegriffen werden. Die vorliegende Erfindung setzt als Teil der elektronischen Schaltung einen Kontaktgeber voraus, der die Verbindungsstelle zwischen der Schaltung und dem Backen bildet. Dieser Kontaktgeber wird bei Erreichen vorgegebener Kräfte betätigt, die in mindestens zwei rechtwinkelige zueinander liegenden Ebenen vom Skischuh auf den Backen übertragen werden.The present invention also does not relate to the electronic circuit, which emits a trigger signal for the jaws after predetermined limit values have been exceeded. In this regard, the prior art can also be used. As part of the electronic circuit, the present invention requires a contactor, which forms the connection point between the circuit and the jaw. This contactor is actuated when predetermined forces are reached, which are transmitted from the ski boot to the cheeks in at least two mutually perpendicular planes.

Der Backen besitzt eine Grundplatte 2, die mittels Schrauben 3 auf einen nicht dargestellten Ski aufschraubbar ist (Fig. 1). In von der Grundplatte abgewinkelten Laschen 4 ist eine horizontale Querachse 5 unbeweglich gehalten. Auf dieser ist ein Sohlenhalter 6 schwenkbar gelagert, der das vordere Sohlenende 1 des Skischuhs seitlich und von oben erfaßt. Der Sohlenhalter ist auf der Querachse unter Zwischenschaltung von zwei Büchsen 7,8 gelagert, die axial unbeweglich gehalten sind. Zwischen den Büchsen ist auf der Querachse 5 eine Schraubendruckfeder 9 gelagert. Der Sohlenhalter 6 ist in der Länge des Abstandes der Büchsen voneinander zylindrisch ausgespart (siehe Fig. 2), so daß sich die Enden der Schraubendruckfeder in der Normalstellung des Sohlenhalters sowohl an den Büchsen als auch an den stirnseitigen Enden der Aussparung abstützen. Wie Fig. 2 weiter erkennen läßt, ist zwischen den Laschen 4 und dem Sohlenhalter 6 jeweils ein Spalt 10 belassen. Auf diese Weise ist dem Sohlenhalter eine begrenzte Bewegungsmöglichkeit gegenüber der Grundplatte nach beiden Seiten hin entgegen der Kraft der Schraubendruckfeder gegeben.The jaw has a base plate 2 which can be screwed onto a ski (not shown) by means of screws 3 (FIG. 1). A horizontal transverse axis 5 is held immovably in tabs 4 angled from the base plate. On this a sole holder 6 is pivotally mounted, which the front sole end 1 of the Ski boots gripped on the side and from above. The sole holder is mounted on the transverse axis with the interposition of two bushings 7, 8, which are held axially immovably. A helical compression spring 9 is mounted on the transverse axis 5 between the bushes. The sole holder 6 is cylindrically recessed in the length of the distance between the sleeves (see FIG. 2), so that the ends of the helical compression spring in the normal position of the sole holder are supported both on the sleeves and on the front ends of the recess. As can also be seen in FIG. 2, a gap 10 is left between the tabs 4 and the sole holder 6. In this way, the sole holder is given a limited possibility of movement relative to the base plate on both sides against the force of the helical compression spring.

Auf der dem Skischuh abgelegenen Seite besitzt der Sohlenhalter 6 zwei Augen 11, die jeweils ein Langloch 12 aufweisen. In diese Langlöcher greift ein Bolzen 13 ein, der parallel zur Querachse 5 liegt und im normalen Gebrauchszustand des Backens gegenüber der Grundplatte 2 in noch zu beschreibender Weise abgestützt ist. In der Normalstellung des Sohlenhalters liegen die äußeren Enden der Langlöcher 12 dem Bolzen 13 federnd an. Hierzu ist in einer Ausnehmung 14 des Sohlenhalters 6 eine Schraubendruckfeder 15 untergebracht, die sich am Bolzen 13 abstützt. Somit ist dem Sohlenhalter entsprechend der Länge der Langlöcher eine Schwenkbewegung um die Querachse 5 entgegen der Kraft der Schraubendruckfeder 15 möglich (siehe Fig. 2). Aus Fig. 1 ist ersichtlich, daß zur Abstützung des vorderen Sohlenendes 1 eine Trittplatte 16 vorgesehen ist. Sie ist an der Grundplatte 2 derart beweglich gehalten, daß sie bei entsprechendem Ballendruck eine Bewegung in Bezug auf die Darstellung nach rechts hin ausführt und damit ein Schwenken des Sohlenhalters 6 ebenfalls entgegen der Kraft der Schraubendruckfeder 15 bewirkt, da der Sohlenhalter einen Arm 17 besitzt, der sich über die Querachse 5 hinaus nach unten erstreckt und dem Rand einer Ausnehmung 18 der Trittplatte 16 anliegt. Die Richtungsänderung des Ballendrucks ergibt sich in bekannter Weise durch das Zusammenwirken entsprechend gestalteter Teile von Trittplatte und Grundplatte nach Art eines Keilschubgetriebes.On the side remote from the ski boot, the sole holder 6 has two eyes 11, each of which has an elongated hole 12. A bolt 13 engages in these elongated holes, which lies parallel to the transverse axis 5 and, in the normal state of use of the jaw, is supported with respect to the base plate 2 in a manner to be described. In the normal position of the sole holder, the outer ends of the elongated holes 12 rest resiliently on the bolt 13. For this purpose, a helical compression spring 15, which is supported on the bolt 13, is accommodated in a recess 14 in the sole holder 6. Thus, the sole holder is able to pivot about the transverse axis 5 against the force of the helical compression spring 15 according to the length of the elongated holes (see FIG. 2). From Fig. 1 it can be seen that a foot plate 16 is provided to support the front sole end 1. It is held on the base plate 2 in such a manner that it can move with respect to the corresponding ball pressure executes the illustration to the right and thus causes the sole holder 6 to also pivot against the force of the helical compression spring 15, since the sole holder has an arm 17 which extends downward beyond the transverse axis 5 and abuts the edge of a recess 18 in the step plate 16 . The change in direction of the bale pressure results in a known manner from the interaction of appropriately designed parts of the tread plate and base plate in the manner of a wedge thrust mechanism.

Auf dem Bolzen 13 ist schwenkbar und in dessen Längsrichtung verschiebbar ein Steuerhebel 21 gelagert. Dieser Steuerhebel erstreckt sich in einen Einschnitt 22 des Sohlenhalters, dessen Breite so gewählt und dessen Grund so gestaltet ist, daß für den Steuerhebel drei Mitnehmer gebildet sind, die bewirken, daß der Steuerhebel sowohl einer Bewegung des Sohlenhalters längs der Querachse 5 als auch um die Querachse folgen kann, wie dies nun anhand der Fig. 3 und 4 beschrieben wird.On the bolt 13, a control lever 21 is pivoted and displaceable in its longitudinal direction. This control lever extends into an incision 22 of the sole holder, the width of which is selected and the base is designed such that three drivers are formed for the control lever, which cause the control lever to move the sole holder both along the transverse axis 5 and around it Transverse axis can follow, as will now be described with reference to FIGS. 3 and 4.

Der in den Figuren 3 und 4 gegenüber den Fig. 1 und 2 vergrößert dargestellte Sohlenhalter 6 befindet sich in seiner weiter vorn beschriebenen Normalstellung. Als Mitnehmer für den Steuerhebel 21 dienen die beiden Seitenflächen 23, 24 des Einschnitts 22 des Sohlenhalters sowie das in Bezug auf Fig. 3 obere Ende 25 des Grundes des Einschnitts. Die auf der Querachse 5 festgelegte Büchse 8 besitzt eine Ringnut 26 mit trapezförmigem Querschnitt. Wie Fig. 3 zeigt, liegt in der Normalstellung des Sohlenhalters der Steuerhebel dem Grund der Ringnut an. Die schrägen Seitenflächen 27,28 der Ringnut bilden Auflaufkurven für den Steuerhebel. Der Steuerhebel ist zweiarmig ausgebildet. Der in Bezug auf Fig. 3 obere Arm ist dabei als Anschlag für das als Mitnehmer dienende Ende 25 des Grundes des Einschnitts 22 vorgesehen. Durch diese Konstruktion ist also erreicht, daß jede Bewegung des Sohlenhalters 6 gegenüber der Querachse 5 eine Drehbewegung des Steuerhebels 21 auf dem Bolzen 13 in Bezug auf Fig. 3 entgegen dem Uhrzeigersinn zur Folge hat.The sole holder 6 shown enlarged in FIGS. 3 and 4 compared to FIGS. 1 and 2 is in its normal position described further above. The two side surfaces 23, 24 of the incision 22 of the sole holder and the upper end 25 of the base of the incision in relation to FIG. 3 serve as drivers for the control lever 21. The sleeve 8 defined on the transverse axis 5 has an annular groove 26 with a trapezoidal cross section. 3 shows, in the normal position of the sole holder, the control lever lies against the bottom of the annular groove. The oblique side surfaces 27, 28 of the annular groove form run-up curves for the control lever. The control lever has two arms. The upper arm in relation to FIG. 3 is provided as a stop for the end 25 of the bottom of the incision 22 serving as a driver. By this construction is thus achieved that each movement of the sole holder 6 with respect to the transverse axis 5 results in a rotary movement of the control lever 21 on the bolt 13 with respect to FIG. 3 counterclockwise.

Diese Bewegung führt nun gemäß der vorliegenden Erfindung bei Erreichen des konstruktiv vorgegebenen Wertes zur Betätigung des weiter vorn beschriebenen Kontaktgebers in der elektronischen Schaltung, wodurch diese zur Abgabe des Auslösesignals zum Öffnen des Backens zwecks Skischuhfreigabe veranlaßt wird.This movement now leads according to the present invention when the structurally predetermined value is actuated to actuate the contactor described above in the electronic circuit, causing it to emit the trigger signal to open the jaw for the purpose of releasing the ski boot.

Im vorliegenden Ausführungsbeispiel bewirkt das Auslösesignal die Erregung eines Elektromagneten der elektronischen Schaltung, der die Betätigung eines als Drehriegel 31 ausgebildeten Sperriegels bewirkt,was zum Öffnen des Backens führt, wie im folgenden beschrieben wird.In the present exemplary embodiment, the trigger signal causes the excitation of an electromagnet of the electronic circuit, which causes the actuation of a locking bar designed as a rotary latch 31, which leads to the opening of the jaw, as will be described below.

Der Bolzen 13, der parallel zur Querachse 5 liegt, den Steuerhebel 21 trägt und an dem sich der Sohlenhalter 6 abstützt, ist in zwei Druckstangen 32 unbeweglich gelagert. Die Druckstangen,die vorzugsweise als Blechstanzstücke ausgebildet sind, sind an ihrem dem Bolzen abgewendeten Ende über einen Achszapfen 33 miteinander verbunden.Dieser Achszapfen trägt in seinem mittleren Bereich eine Rolle 34, über die sich die Druckstangen auf der Grundplatte 2 abstützen. Weiter bildet der Achszapfen 33 das Verschiebegelenk eines Kniehebels, dessen einer Arm aus zwei kongruenten Blechstanzstücken 35 besteht, die zwischen der Rolle und den Druckstangen auf dem Achszapfen gelagert sind (siehe insbesondere Fig. 2). Der andere Arm des Kniehebels ist zentral angeordnet und mit 36 bezeichnet. Er ist auf einer Achse 37 gelagert, die in von der Grundplatte 2 abgewinkelten Laschen 38 gehalten ist. Jede Lasche weist noch ein Loch 39 auf, in das jeweils ein Ende jeweils einer Schraubenzugfeder 40 eingehängt ist. Diese Federn dienen als Rückstellfedern für den Kniehebel und greifen mit ihren hakenförmig gestalteten Wirkenden in Ringnuten eines Achszapfens41 ein, der die Kniehebelarme 35, 36 miteinander verbindet und somit das Kniegelenk bildet. Der Kniehebelarm 36 ist in Bereich des Kniegelenkes derart ausgespart, daß der zentrale Teil des Achszapfens 41 freigelegt ist. Dieser Teil wird in der Normallage des Backens (siehe Fig. 1 und 2) von dem Drehriegel 31 übergriffen, so daß die gesamte Getriebeanordnung, die als Sperreinrichtung für den Sohlenhalter 6 dient, lagegesichert ist. Der Drehriegel 31 steht unter dem Einfluß einer nicht dargestellten schwachen Haltefeder, die ihn in Bezug auf Fig. 1 entgegen dem Uhrzeigersinn belastet. Die Bewegung des Drehriegels in diese Richtung ist durch eine Nase 42 begrenzt, die an der Grundplatte 2 anschlägt. Der Drehriegel ist auf einer Achse 43 an der Grundplatte gelagert. Diese Achse und auch die drei Achsen des Kniehebels liegen parallel zum Bolzen 13 und damit auch zur Querachse 5.The bolt 13, which is parallel to the transverse axis 5, carries the control lever 21 and on which the sole holder 6 is supported, is immovably mounted in two push rods 32. The pressure rods, which are preferably designed as sheet metal stampings, are connected to one another at their end facing away from the bolt via an axle journal 33. This axle journal carries in its central region a roller 34, by means of which the pressure rods are supported on the base plate 2. Furthermore, the journal 33 forms the sliding joint of a toggle lever, one arm of which consists of two congruent sheet metal stampings 35, which are mounted on the journal between the roller and the push rods (see in particular FIG. 2). The other arm of the knee lever is arranged centrally and with 36 designated. It is mounted on an axis 37 which is held in tabs 38 angled from the base plate 2. Each tab also has a hole 39, in each of which one end of a helical tension spring 40 is suspended. These springs serve as return springs for the toggle lever and engage with their hook-shaped ends in ring grooves of an axle pin 41 which connects the toggle lever arms 35, 36 to one another and thus forms the knee joint. The toggle lever arm 36 is recessed in the area of the knee joint in such a way that the central part of the journal 41 is exposed. This part is overlapped in the normal position of the jaw (see FIGS. 1 and 2) by the rotary latch 31, so that the entire gear arrangement, which serves as a locking device for the sole holder 6, is secured in position. The rotary latch 31 is under the influence of a weak retaining spring, not shown, which loads it counterclockwise in relation to FIG. 1. The movement of the rotary latch in this direction is limited by a lug 42 which strikes the base plate 2. The rotary bolt is mounted on an axis 43 on the base plate. This axis and also the three axes of the toggle lever lie parallel to the bolt 13 and thus also to the transverse axis 5.

In den Fig. 1 bis 4 nimmt der Backen bzw. seine beweglichen Einzelteile die Normallage ein, in der ein sich in der Bindung befindender Skischuh sicher auf dem Ski gehalten wird. Wie bereits gesagt, ist der Sohlenhalter 6 auf der Querachse 5 unter Überwindung der Kraft der Schraubendruckfeder 9 längs der Querachse nach beiden Seiten hin entsprechend der Breite des jeweiligen Spaltes 10 verschiebbar. Außerdem ist der Sohlenhalter um die Querachse 5 entgegen der Kraft der Schraubendruckfeder 15 durch die Länge der Langlöcher 12 begrenzt schwenkbar. Während die Querbewegung durch eine ausreichend große seitliche Kraft in die entsprechende Richtung erfolgt, ergibt sich die Schwenkbewegung sowohl bei ausreichender Rückwärts- als auch Vorwärtsbelastung, daß heißt bei entsprechendem vom vorderen Sohlenende 1 ausgeübten Zug oder Druck. Diese Bewegungen des Sohlenhalters gegenüber der Querachse führen in jedem Fall zu einer Drehbewegung des Steuerhebels 21 auf den Bolzen 13. Am Ende seiner Drehbewegung betätigt der Steuerhebel 21 dann den Kontaktgeber in der elektronischen Schaltung, was in bekannter Weise die Erregung eines Elektromagneten bewirkt,der den Drehriegel 31 entgegen der Kraft dessen schwacher Haltefeder in seine Offenstellung schwenkt. Durch die Kraftübertragung von der Schuhsohle auf den Sohlenhalter übt dieser einen Druck auf die Druckstangen 32 aus,die nunmehr nicht mehr zurückgehalten werden, so daß sich der in Fig. 5 dargestellte Momentanzustand einstellt, in dem das vordere Sohlenende 1 vom Sohlenhalter 6 freikommt.1 to 4, the jaws or its movable individual parts assume the normal position in which a ski boot located in the binding is held securely on the ski. As already mentioned, the sole holder 6 can be displaced on the transverse axis 5 by overcoming the force of the helical compression spring 9 along the transverse axis to both sides in accordance with the width of the respective gap 10. In addition, the sole holder can be pivoted to a limited extent about the transverse axis 5 against the force of the helical compression spring 15 by the length of the elongated holes 12. During the transverse movement by a sufficiently large lateral force in the corresponding direction, the pivoting movement results both with sufficient backward and forward loading, that is, with a corresponding pull or pressure exerted by the front sole end 1. These movements of the sole holder with respect to the transverse axis in any case lead to a rotary movement of the control lever 21 on the bolt 13. At the end of its rotary movement, the control lever 21 then actuates the contactor in the electronic circuit, which in a known manner causes the excitation of an electromagnet which causes the Rotary bolt 31 pivots against the force of its weak retaining spring in its open position. Due to the power transmission from the shoe sole to the sole holder, this exerts pressure on the push rods 32, which are now no longer held back, so that the instantaneous state shown in FIG. 5 is reached, in which the front sole end 1 is released from the sole holder 6.

Der Sohlenhalter hat eine entsprechende Schwenkbewegung um die Querachse 5 ausgeführt und die Rolle 34 ist auf der Grundplatte 2 ein entsprechendes Stück nach vorne gerollt. Dieses wurde durch Entriegeln und Hochschwenken des Kniegelenks 41 ermöglicht. Unmittelbar nach Freikommen des vorderen Sohlenendes vom Sohlenhalter stellt sich dieser jedoch aus der Freigabeposition nach Fig. 5 in die Normallage nach Fig. 1 zurück. Dieses geschieht unter dem Einfluß der Schraubenzugfedern 40, die beim Hochschwenken des Kniehebels gespannt wurden und die diesen nun zurückziehen. Dabei läuft das Kniegelenk an dem Riegelende des Drehriegels 31 vorbei, der bereits unter dem Einfluß seiner Haltefeder wieder seine Ausgangsposition eingenommen hatte.The sole holder has carried out a corresponding pivoting movement about the transverse axis 5 and the roller 34 is rolled forward on the base plate 2 by a corresponding amount. This was made possible by unlocking and swiveling up the knee joint 41. Immediately after the front sole end is released from the sole holder, however, the sole holder returns from the release position according to FIG. 5 into the normal position according to FIG. 1. This takes place under the influence of the coil tension springs 40, which were tensioned when the toggle lever was swung up and which now pull it back. The knee joint runs past the bolt end of the rotary bolt 31, which had already returned to its starting position under the influence of its retaining spring.

Soll der dargestellte und beschriebene Backen jedoch nur als Meßbacken Verwendung finden, so kann auf die lösbare Sperreinrichtung verzichtet werden. Der Bolzen 13 ist dann statt in den Druckstangen 32 einfach fest an der Grundplatte 2 zu lagern. In einem derartigen Fall erfolgt die Schuhfreigabe durch den zweiten das hintere Sohlenende haltenden Backen, wenn dieser von der elektronischen Schaltung nach Überschreiten vorgegebener Grenzwerte den Auslösebefehl erhält.However, if the jaws shown and described are only to be used as measuring jaws, the releasable locking device can be dispensed with. The bolt 13 is then simply fixed to the base plate 2 instead of in the push rods 32 to store. In such a case, the shoe is released by the second jaw holding the rear sole end when the latter receives the trigger command from the electronic circuit after predetermined limit values have been exceeded.

Wenn die Verwendung des erfindungsgemäßen, in den Ansprüchen als erster bezeichneten Backens als Vorderbacken als vorteilhaft angesehen wird, so ist es dennoch möglich, ihn auch als Fersenhalter zu konzipieren. Insbesondere in diesem Fall ist es dann vorteilhaft, den Drehriegel 31 derart zu gestalten, daß er eine Handhabe zum willkürlichen Öffnen des Backens bietet.If the use of the cheek according to the invention, referred to as the first in the claims, is considered to be advantageous as a toe, it is nevertheless possible to design it as a heel holder. In this case in particular, it is then advantageous to design the rotary latch 31 in such a way that it offers a handle for opening the jaw arbitrarily.
