Description

Die Erfindung betrifft einen Vorderbacken einer Skibindung mit einem Gehäuse und mit zwei am Gehäuse angeordneten, um vertikale Hochachsen schwenkbaren Sohlenhaltern, welche als zweiarmige Hebel ausgebildet sind, deren eine Hebelarme den vorderen Endbereich des Sohlenrandes eines Skischuhs halten und deren zweite Hebelarme mit Druckelementen zusammenwirken, die in Skiquerrichtung bewegbar sind und von einer zwischen ihnen befindlichen, sich in Skiquerrichtung erstreckenden Feder beaufschlagt sind.The invention relates to a front jaw of a ski binding with a housing and two arranged on the housing, pivotable about vertical axis pivoting sole holders, which are designed as two-armed lever whose lever arms hold the front end portion of the sole edge of a ski boot and their second lever arms interact with pressure elements, the are moved in the direction of the cross-section and are acted upon by a spring located between them and extending in the transverse direction.

Ein derartiger Vorderbacken ist aus der EP 1 892 020 A2 bekannt. Die von der Feder beaufschlagten Elemente sind als Kolben ausgeführt, welche in einem zylinderartigen Gehäuse, welches eine zur Querrichtung parallele Zylinderachse aufweist, verschiebbar geführt sind. An der dem jeweiligen Sohlenhalter zugewandten Außenseite des Kolbenbodens jedes Kolbens ist eine mit dem sohlenfernen Arm des jeweiligen Sohlenhalters zusammenwirkende Kulissenbahn angeordnet, die durch eine Erhebung in zwei Abschnitte unterteilt ist, wobei der Sohlenhalter in Auslöseposition an dem einen Abschnitt festgehalten wird. Durch die bei einer Auslösung stattfindende Gleitreibung zwischen den Federendabschnitten und den Innenseiten der Kolben, in welchen die Feder gehalten ist, und zwischen den Außenseiten der Kolben und dem zylinderförmigen Gehäuse wird die Auslösekraft beeinflusst.Such a toe is from the EP 1 892 020 A2 known. The acted upon by the spring elements are designed as pistons, which are guided in a cylinder-like housing, which has a parallel to the transverse direction of the cylinder axis, slidably. At the respective sole holder facing the outside of the piston head of each piston cooperating with the sol away arm of the respective sole holder slide track is arranged, which is divided by a survey in two sections, wherein the sole holder is held in the release position on the one section. The release force is influenced by the sliding friction occurring between the spring end sections and the inner sides of the pistons in which the spring is held, and between the outer sides of the pistons and the cylindrical housing.

Der Erfindung liegt die Aufgabe zugrunde, einen Vorderbacken der eingangs genannten Art derart zu gestalten, dass eine die Auslösekraft beeinflussende Gleitreibung reduziert ist.The invention has for its object to make a toe of the type mentioned in such a way that a release force influencing sliding friction is reduced.

Gelöst wird die gestellte Aufgabe erfindungsgemäß dadurch, dass die Feder an einzelnen, in Skiquerrichtung am Gehäuse oder an einem gehäusefesten Teil ausgebildeten Führungsrippen geführt ist und dass die Druckelemente von Biegeblechstreifen getragen oder gebildet sind, welche am Gehäuse beweglich gelagert sind und bei einer Auslösung verformbar bzw. verbiegbar sind.This object is achieved according to the invention in that the spring is guided on individual guide ribs formed on the housing or on a part fixed to the housing in the direction of the ski, and that the pressure elements are supported by bending strips or are formed, which are movably mounted on the housing and are deformable or bendable when triggered.

Die Druckelemente kommen somit nicht in Kontakt mit dem Gehäuse, da sie von Biegeblechstreifen getragen oder gebildet werden, die am Gehäuse beweglich gelagert sind. Die Feder selbst ist am bzw. im Gehäuse geführt, wobei zu ihrer Führung lediglich Führungsrippen vorgesehen sind, die die Feder nur im erforderlichen Ausmaß in Querrichtung positionieren. Die gesamte erfindungsgemäße Konstruktion ist daher sehr reibungsarm ausgelegt, wodurch eine definierte und gleichbleibende Auslösekraft bei einer Auslösung der Sohlenhalter gewährleistet ist.The printing elements thus do not come into contact with the housing, since they are supported or formed by bending strip, which are movably mounted on the housing. The spring itself is guided on or in the housing, with their guide only guide ribs are provided which position the spring only to the extent required in the transverse direction. The entire construction according to the invention is therefore designed very low friction, whereby a defined and constant release force is guaranteed at a release of the sole holder.

Bei einer bevorzugten Ausführungsform der Erfindung sind die Biegeblechstreifen zumindest abschnittsweise gebogen ausgeführt. Bevorzugt sind die Biegeblechstreifen, in der geschlossenen Lage des Vorderbackens und bezüglich der Skilängsachse betrachtet, konkav gebogen. Die Form der Biegeblechstreifen kann daher vorteilhafterweise an den gewünschten Federweg beim Komprimieren der Feder abgestimmt werden.In a preferred embodiment of the invention, the bending strip strips are executed bent at least in sections. Preferably, the bending strip, in the closed position of the toe and viewed with respect to the ski longitudinal axis, concavely bent. The shape of the bending strip can therefore be advantageously adapted to the desired travel when compressing the spring.

Bei einer weiteren bevorzugten Ausführungsform der Erfindung sind die Druckelemente insbesondere aus Kunststoff bestehende Teile, die mit dem Biegeblechstreifen fest verbunden sind. Gesonderte Druckelemente können auf einfach Weise mit einer Steuerkurve zur Beeinflussung des Auslöseverhaltens des Vorderbackens ausgeführt werden. Dabei kann die an der Außenseite der Druckelemente gebildete Gleitfläche für die zweiten Hebelarme der Sohlenhalter auch als eine ebene Fläche ausgeführt sein.In a further preferred embodiment of the invention, the pressure elements are in particular made of plastic parts which are firmly connected to the bending strip. Separate printing elements can be easily carried out with a control cam to influence the release behavior of the toe. In this case, the sliding surface formed on the outer side of the pressure elements for the second lever arms of the sole holder can also be designed as a flat surface.

Zur beweglichen Lagerung der Biegeblechstreifen können diese gemäß der Erfindung mit ihrem einen Ende im Gehäuse verankert, beispielsweise eingehängt, sein und mit ihrem zweiten Ende im Gehäuse in Querrichtung beweglich gelagert sein. Durch diese Art der beweglichen Lagerung wird die Reibung zwischen den Biegeblechstreifen und dem Gehäuse gering gehalten.For movable mounting of the bending strip these can be anchored according to the invention with its one end in the housing, for example, hung, and be mounted with its second end in the housing in the transverse direction movable. By this type of movable storage, the friction between the bending strip and the housing is kept low.

Die Auslösefeder soll auf zweckmäßige Weise in ihrer Vorspannung veränderbar sein. Die Feder beaufschlagt daher das eine Druckelement oder den einen Biegeblechstreifen unmittelbar und das zweite Druckelement oder den zweiten Biegeblechstreifen über ein verstellbares Federwiderlager.The release spring should be changed in an appropriate manner in their bias. The spring therefore acts on the one pressure element or the one bending strip directly and the second pressure element or the second bending strip on an adjustable spring abutment.

Um die Auslösefeder in einer definierten Position am Druckelement bzw. am Biegeblechstreifen abzustützen, ist es günstig, wenn an der Innenseite des von der Feder unmittelbar beaufschlagten Druckelementes oder Biegeblechstreifens ein Positionierelement für den Endabschnitt der Feder angeordnet ist, wobei das Positionierelement auf einfache Weise entweder als zylindrischer Teil ausgebildet sein kann, welcher an der Innenseite des Druckelementes vorgesehen ist, oder von ringartig angeordneten Blechflügeln des Biegeblechstreifens gebildet ist.In order to support the release spring in a defined position on the pressure element or on the bending strip, it is advantageous if a positioning element for the end portion of the spring is arranged on the inside of the spring directly acted upon by the spring pressure element or bending strip, wherein the positioning element in a simple manner either as cylindrical part may be formed, which is provided on the inside of the pressure element, or is formed by annularly arranged sheet metal wings of the bending strip.

Das verstellbare Federwiderlager kann auf einfache Weise an einer von der Feder an das Druckelement oder den Biegeblechstreifen gedrückten Stellschraube angeordnet sein, an dieser Stellschraube in Querrichtung des Vorderbackens verstellbar und gegenüber dem Gehäuse axial unverdrehbar gehalten sein.The adjustable spring abutment can be arranged in a simple manner on one of the spring pressed against the pressure element or the bending strip strip screw, be adjustable on this adjusting screw in the transverse direction of the front jaw and axially held against the housing axially.

Jedes Druckelement 7, 8 sitzt auf einem Biegeblechstreifen 10, 11, welcher sich in Längsrichtung SL erstreckt und gebogene Endabschnitte 10a, 10b, 11a, 11b aufweist, derart, dass jeder Biegeblechstreifen 10, 11 in der Abfahrtsstellung bzw. der geschlossenen Lage (Fig. 2) des Vorderbackens 1, bezüglich der Skilängsachse SL betrachtet, insgesamt leicht konkav gekrümmt ist. Die Biegeblechstreifen 10, 11 tragen die Druckelemente 7, 8 und können von den Sohlenhaltern 5, 6 durch Ausüben von Druck auf die Druckelemente 7, 8 und unter gleichzeitiger Bewegung der Druckelemente 7, 8 in Querrichtung Q soweit verbogen werden, dass sie in der Auslösestellung (Fig. 5, Fig. 5a) bezüglich der Skilängsachse SL konvex gebogen sind.On the housing 2 symmetrically to the ski longitudinal axis S L two vertically extending bolts 4 are arranged, which form vertical axes for the pivotal mounting of two-armed sole holders 5, 6 and enforce the sole holder 5, 6. Each sole holder 5, 6 has an arm 5a, 6a, which is designed such that it engages over the front portion of the sole of a ski boot inserted in the toe 1 from above and at the edge and rests laterally against the sole. The second arm 5b, 6b respectively acts on a pressure element 7, 8 (FIG. 8) aligned parallel to the ski longitudinal axis S L (FIG. Fig. 2 to 6 ) or 20 ( Fig. 7 ), which in the illustrated embodiments on its outer side provides a planar sliding surface for the arms 5b, 6b. The pressure elements 7, 8 are inside the jaw in a manner to be described under the action of a helical compression spring 9, which extends transversely to the ski longitudinal axis S L between the two pressure elements 7, 8 in the transverse direction Q. Each pressure element 7, 8 is seated on a bending strip 10, 11 which extends in the longitudinal direction S L and bent end portions 10 a, 10 b, 11 a, 11 b, such that each bending strip 10, 11 in the down position or the closed position ( Fig. 2 ) of the front jaw 1, viewed with respect to the ski longitudinal axis S L , is slightly concave curved overall. The bending strip 10, 11 bear the pressure elements 7, 8 and can be bent from the sole holders 5, 6 by exerting pressure on the pressure elements 7, 8 and with simultaneous movement of the pressure elements 7, 8 in the transverse direction Q, that they are in the release position ( Fig. 5 . Fig. 5a ) are curved convexly with respect to the ski longitudinal axis S L.

Das Druckelement 7 weist einen insbesondere scheibenförmig ausgebildeten Außenteil 7a und einen insbesondere zylindrisch gestalteten Ansatz 7b auf, welcher eine Öffnung im Biegeblechstreifen 10 durchsetzt und außenseitig mit einem Sicherungsring 7c fest verbunden ist. Sicherungsring 7c und Ansatz 7b bilden ein Positionierelement für den Endabschnitt der Feder 9.The pressure element 7 has a particular disk-shaped outer part 7a and a particular cylindrically shaped projection 7b, which has an opening in the Bending strip 10 passes through and outside is firmly connected to a retaining ring 7c. Circlip 7c and projection 7b form a positioning element for the end portion of the spring. 9

Das Druckelement 8 weist einen insbesondere scheibenförmig ausgeführten Außenteil 8a und einen ebenfalls etwa scheibenförmig gestalteten Innenteil 8b auf, wobei zwischen Außen- und Innenteil 8a, 8b der Biegeblechstreifen 11 gehalten ist. Der Außen- und der Innenteil 8a, 8b sind miteinander fest verbunden, beispielsweise über Schnappverbindungen.The pressure element 8 has an in particular disc-shaped outer part 8a and also an approximately disk-shaped inner part 8b, wherein between the outer and inner part 8a, 8b of the bending strip 11 is held. The outer and inner parts 8a, 8b are fixedly connected to each other, for example via snap connections.

Der eine Endabschnitt 10a, 11a jedes Biegeblechstreifens 10, 11 ist am Gehäuse 2 gehalten, bei der gezeigten Ausführungsform an seinem Ende zusätzlich umgebogen und greift hinter einen Vorsprung 12 des Gehäuseunterteils 2b. Der zweite Endeabschnitt 10b, 11b jedes Biegeblechstreifens 10, 11 ist gegenüber dem Gehäuse 2 beweglich angeordnet, wobei im Gehäuse 2, bei der gezeigten Ausführung zwischen dem Gehäuseoberteil 2b und dem Gehäuseunterteil 2b, ein Freiraum vorhanden ist, sodass sich der Endabschnitt 10b, 11b in der Abfahrtsstellung (Fig. 4a) an einer Stützfläche des Gehäuseoberteils 2a und in der Auslösestellung (Fig. 5a) an einer dieser gegenüberliegenden Stützfläche des Gehäuseunterteils 2b abstützt. Der Freiraum zwischen den Stützflächen ermöglicht die oben erwähnte Verformung der Biegeblechstreifen 10, 11 bei einer Auslösung.The one end portion 10a, 11a of each bending strip 10, 11 is held on the housing 2, in the embodiment shown additionally bent at its end and engages behind a projection 12 of the housing base 2b. The second end portion 10b, 11b of each bending strip 10, 11 is arranged movable relative to the housing 2, wherein in the housing 2, in the embodiment shown between the housing top 2b and the housing base 2b, a space is available, so that the end portion 10b, 11b in the departure position ( Fig. 4a ) on a support surface of the housing upper part 2a and in the release position ( Fig. 5a ) is supported on one of these opposite support surface of the lower housing part 2b. The clearance between the support surfaces allows the above-mentioned deformation of the bending strip 10, 11 at a release.

Die Schraubendruckfeder 9 ist beim Druckelement 7 mit ihrem einen Ende am Biegeblechstreifen 10 abgestützt. Zwischen den beiden Druckelementen 7, 8 ist die Schraubendruckfeder 9 am Gehäuse 2, insbesondere an mehreren in Querrichtung verlaufenden, am Gehäuseoberteil 2a und am Gehäuseunterteil 2b ausgebildeten Führungsrippen 13, geführt.The helical compression spring 9 is supported at the pressure element 7 with its one end on the bending strip 10. Between the two pressure elements 7, 8, the helical compression spring 9 is guided on the housing 2, in particular on several transverse in the transverse direction, formed on the upper housing part 2a and the lower housing part 2b guide ribs 13.

Das zweite Ende der Schraubendruckfeder 9 ist an einem Federwiderlager 14 abgestützt, welches über eine Stellschraube 15 am zweiten Druckelement 8 abgestützt ist und gegenüber diesem in Querrichtung Q verstellbar ist, um die Vorspannung der Schraubendruckfeder 9 zur Einstellung der Auslösekräfte der Sohlenhalter 5, 6 zu verändern. Das Federwiderlager 14 ist ein im Wesentlichen ringförmiger Bauteil, welcher eine zentrale Öffnung 14a mit einem Innengewinde aufweist, mittels welchem das Federwiderlager 14 auf einem Gewindeabschnitt der Stellschraube 15 sitzt, welche gegenüber dem Druckelement 8 drehbar ist. Der Schraubkopf 15a der Stellschraube 15 ist von der Außenseite des Druckelementes 8 zugänglich und mittels eines herkömmlichen Werkzeuges betätigbar. Das Federwiderlager 14 ist an seinem Außenumfang mit einem Führungsansatz 14b (Fig. 6) versehen, welcher in eine am Gehäuse 2 ausgebildete Führungsnut 16 eingreift, sodass das Federwiderlager 14 unverdrehbar gehalten, jedoch in Querrichtung Q beweglich ist. Somit bewirkt ein Drehen der Stellschraube 15 eine entsprechende Längsbewegung des Federwiderlagers 14 an der Stellschraube 15 und damit eine Verstellung des gegenseitigen Abstandes zwischen dem Federwiderlager 14 und dem Druckelement 7. Das Federwiderlager 14 weist ferner am oberen Bereich seines Außenumfanges ein Anzeigeelement 17 auf, welches gemeinsam mit einer Skala 18 im Bereich eines Fensters 19 des Gehäuses 2 (Fig. 1) ein Ablesen der eingestellten Federvorspannung gestattet.The second end of the helical compression spring 9 is supported on a spring abutment 14 which is supported via an adjusting screw 15 on the second pressure element 8 and relative to this in the transverse direction Q is adjustable to the bias of the helical compression spring 9 for adjusting the triggering forces of the sole holder 5, 6 to change. The spring abutment 14 is a substantially annular member having a central opening 14a with an internal thread, by means of which the spring abutment 14 is seated on a threaded portion of the adjusting screw 15, which is rotatable relative to the pressure element 8. The screw head 15a of the adjusting screw 15 is accessible from the outside of the pressure element 8 and actuated by means of a conventional tool. The spring abutment 14 is provided at its outer periphery with a guide lug 14b (FIG. Fig. 6 ), which engages in a housing groove 2 formed on the guide groove 16, so that the spring abutment 14 held non-rotatably, but in the transverse direction Q is movable. Thus, a rotation of the adjusting screw 15 causes a corresponding longitudinal movement of the spring abutment 14 on the adjusting screw 15 and thus an adjustment of the mutual distance between the spring abutment 14 and the pressure element 7. The spring abutment 14 further has at the top of its outer periphery a display element 17, which together with a scale 18 in the region of a window 19 of the housing 2 (FIG. Fig. 1 ) allows reading the set spring preload.

Bei einer Auslösung des Vorderbackens und einer damit einhergehenden Freigabe eines eingesetzten Skischuhs wird der vom Skischuh seitlich beaufschlagte Sohlenhalter - in Fig. 5 und 5a ist es der Sohlenhalter 5 - um seinen Bolzen 4 nach außen verschwenkt. Dabei drückt der Hebelarm 5b auf das Druckelement 7 und gleitet entlang der Außenseite des Druckelementes 7. Der Biegeblechstreifen 10 wird gleichzeitig in Querrichtung Q unter entsprechender Verformung und gemeinsam mit dem Druckelement 7 bewegt und komprimiert dabei die Schraubendruckfeder 9. Nach der Freigabe des Skischuhs wird der Sohlenhalter 5 unter der Wirkung der Schraubendruckfeder 9 wieder in seine Ausgangslage gebracht. Eine Freigabe des Skischuhs durch ein Verschwenken des anderen Sohlenhalters 6 erfolgt auf analoge Weise.When triggering the front jaw and a concomitant release of a used ski boot is the side of the ski boot acted on sole holder - Fig. 5 and 5a it is the sole holder 5 - pivoted about its pin 4 to the outside. The bending arm strip 10 is moved simultaneously in the transverse direction Q under appropriate deformation and together with the pressure element 7 and thereby compresses the helical compression spring 9. After the release of the ski boot is the Sole holder 5 brought under the action of the helical compression spring 9 back to its original position. A release of the ski boot by pivoting the other sole holder 6 takes place in an analogous manner.

Zur Herstellung der Verbindung zwischen den Druckelementen 7, 8 und den Biegeblechstreifen 10, 11 können letztere auch mit Kunststoff umspritzt werden.To produce the connection between the pressure elements 7, 8 and the bending strip 10, 11, the latter can be encapsulated with plastic.

Das in Fig. 7 gezeigte Ausführungsbeispiel unterscheidet sich von jener gemäß den Figuren 2 bis 6 durch die Ausführung der Druckelemente, von welchen nur jenes dargestellt ist, das kein verstellbares Federwiderlager trägt. Das Druckelement ist ein Biegeblechstreifen 20, dessen Funktion und Anordnung am Gehäuse 2 jener der Biegeblechstreifen 10, 11 entspricht und welcher an seiner Innenseite unmittelbar von der in Fig. 7 nicht gezeigten Feder 9 beaufschlagt ist. Die Biegeblechstreifen 20 weisen ebene, mittige Abschnitte 20b auf, an welchen die Arme 5b, 6b der Sohlenhalter 5, 6 außenseitig abgestützt sind und entlang welcher die Arme 5b, 6b während eines Auslösevorganges gleiten. Als Positionierelement für die Feder 9 weist der in Fig. 7 gezeigte Biegeblechstreifen 20 mittig eine Anzahl von im rechten Winkel abstehenden kurzen Blechflügeln 20a auf, die aus dem Material des Biegeblechstreifens 20 durch das Ausbilden eines mittigen Loches gebildet werden können. Am zweiten, nicht gezeigten Biegeblechstreifen 20 kann das verstellbare Federwiderlager analog zur ersten Ausführungsform angeordnet sein.This in Fig. 7 embodiment shown differs from that according to the FIGS. 2 to 6 by the design of the pressure elements, of which only that is shown, which carries no adjustable spring abutment. The pressure element is a bending strip 20 whose function and arrangement on the housing 2 corresponds to those of the bending strip 10, 11 and which on its inside directly from the in Fig. 7 not shown spring 9 is acted upon. The bending strip strips 20 have flat, central portions 20b, on which the arms 5b, 6b of the sole holders 5, 6 are supported on the outside and along which the arms 5b, 6b slide during a tripping operation. As a positioning element for the spring 9, the in Fig. 7 shown bending strip strips 20 centered on a number of protruding at right angles short sheet metal wings 20a, which can be formed from the material of the bending strip 20 by the formation of a central hole. At the second, not shown bending strip 20, the adjustable spring abutment can be arranged analogously to the first embodiment.

Die Biegeblechstreifen können auch derart ausgeführt sein, dass sie gerade sind oder konvex gebogen sind und bei einer Auslösung von dieser Form in eine konvexe oder mehr konvex gebogene Form gelangen. Wesentlich ist, dass sie gegen die Kraft der Feder 9 verbiegbar bzw. verformbar sind. Anstelle von ebenen Gleitflächen für die Arme 5b, 6b der Sohlenhalter 5, 6 können die Druckelemente 7, 8, 20 auch speziell geformte Steuerflächen aufweisen, um die Auslösecharakteristik zu beeinflussen.The bending strip can also be designed so that they are straight or curved convexly and reach a tripping of this form in a convex or more convexly curved shape. It is essential that they are bendable or deformable against the force of the spring 9. Instead of plane sliding surfaces for the arms 5b, 6b of the sole holders 5, 6, the pressure elements 7, 8, 20 may also have specially shaped control surfaces in order to influence the tripping characteristic.
