Description

Sicherheitsskibindung Ski safety
Die Erfindung bezieht sich auf eine Sicherheitsskibindung gemäß dem Oberbegriff des Anspruches 1.The invention relates to a safety ski binding according to the preamble of claim 1.
Eine derartige Sicherheitsskibindung ist beispielsweise in der DE-A1-3342 155 beschrieben. Bei dieser Ausführungsform einer Skibindung ist die Auslösung des Skischuhs bei einem Drehsturz insofern unbefriedigend, als bei einem seitlichen Ausschwenken der Sohlenplatte die Vorspannung der Rastfeder, welche den Sohlenhalter in der Fahrtstellung hält, erhöht wird; dies kann mitunter zu Überbeanspruchungen, insbesondere des Knöchels, Anlaß geben.Such a safety ski binding is described for example in DE-A1-3342 155. In this embodiment of a ski binding, the triggering of the ski boot in the event of a fall is unsatisfactory insofar as the pretension of the detent spring, which holds the sole holder in the driving position, is increased when the sole plate is pivoted out to the side; this can occasionally lead to overstressing, especially of the ankle.
Die Erfindung stellt sich die Aufgabe, diesen Nachteil zu beseitigen und eine Sicherheitsskibindung zu schaffen, welche eine zusätzliche Freigabe des Skischuhs durch eine Relativbewegung des Fersenhalters gegenüber der Sohlenplatte auch bei reiner horizontaler Belastung gewährleistet. Dabei soll auch bei einem Rückwärtsdrehsturz des Skiläufers eine Auslösung des Fersenhalters ermöglicht werden. Allerdings ist hiefür die Verwendung eines am Sohlenhalter angelenkten und in der Einstiegsstellung an demselben abgestützten Trittspornes erforderlich, wie er in der AT-A2-378 691 beschrieben ist.The object of the invention is to eliminate this disadvantage and to create a safety ski binding which ensures an additional release of the ski boot by a relative movement of the heel holder with respect to the sole plate even with a pure horizontal load. It should also be possible to trigger the heel holder if the skier falls backwards. However, this requires the use of a step spur articulated on the sole holder and supported in the entry position on the same as described in AT-A2-378 691.
Ausgehend von einer Skibindung gemäß dem Oberbegriff des Anspruches 1 wird diese Aufgabe erfindungsgemäß durch die Merkmale des kennzeichnenden Teiles dieses Anspruches gelöst« Durch diese Merkmale wird erreicht, daß der Lagerbock nur innerhalb eines vorgegebenen Schwenkwinkels gegsnüber der Sohlenplatte verriegelt ist; überschreitet die Auslenkung jedoch diesen Winkel, so wiiTd der Lagerbock freigegeben und kann sich gegenüber der Sohlenplatte verdrehen.Starting from a ski binding according to the preamble of claim 1, this object is achieved according to the invention by the features of the characterizing part of this claim. «With these features it is achieved that the bearing block is locked against the sole plate only within a predetermined pivoting angle; However, if the deflection exceeds this angle, the pedestal is released and can be opposite the sole plate twist.
Für eine konstruktiv besonders einfache Ausgestaltung bietet sich die Maßnahme des Anspruches 2 an.The measure of claim 2 lends itself to a structurally particularly simple embodiment.
Durch den Gegenstand des Anspruches 3 wird die Anordnung der Steuerkurve für den Sohlenhalter vereinfacht.The object of claim 3 simplifies the arrangement of the control curve for the sole holder.
Schließlich ermöglicht es die Maßnahme des Anspruches 4, die Vorspannung derjenigen Druckfeder zu variieren, welche der Rolle zugeordnet ist, die an der an der Grundplatte vorgesehenen oteuerkurve abrollt.Finally, the measure of claim 4 makes it possible to vary the pretension of that compression spring which is assigned to the roller which rolls on the oteur curve provided on the base plate.
In der Zeichnung ist eine beispielsweise Ausführungsform des Erfindungsgegenstandes dargestellt. Fig. 1 ist ein Schnitt durch eine Skibindung nach der Linie I - I in Fig. 2 und Fig. 2 ein Schnitt nach der Linie II - II in Fig. 1. Fig. 3 gibt einen der Fig. 1 entsprechenden Schnitt in der ausgelösten Lage des Fersenhalters nach einem Frontalsturz wieder. In Fig. 4 ist ein abgeändertes Detail zu Fig. 1 in größerem Maßstab dargestellt.An example embodiment of the subject matter of the invention is shown in the drawing. Fig. 1 is a section through a ski binding along the line I - I in Fig. 2 and Fig. 2 is a section along the line II - II in Fig. 1. Fig. 3 shows a section corresponding to Fig. 1 in the triggered Position of the heel holder again after a frontal fall. 4 shows a modified detail of FIG. 1 on a larger scale.
In Fig. 1 ist mit 1 ein Ski und mit 2 ein Fersenhalter in seiner Gesamtheit bezeichnet. Letzterer 1a besitzt eine an der Skioberseite/zu befestigende Grundplatte 3, welche mit einem vertikalen Drehzapfen 4 versehen ist. Auf diesem Drehzapfen 4 ist eine Sohlenplatte 8 chwenkbar gelagert, welche zur Auflage eines nicht dargestellten Skischuhs dient.In Fig. 1, 1 denotes a ski and 2 a heel holder in its entirety. The latter 1a has a base plate 3, which is to be fastened to the top of the ski / and is provided with a vertical pivot pin 4. On this pivot 4, a sole plate 8 is pivotally mounted, which serves to support a ski boot, not shown.
Der Fersenhalter 2 ist von bekannter Bauart.The heel holder 2 is of a known type.
Er besitzt einen Trittsporn 7 und einen Sohlenhalter welch letztererIt has a step spur 7 and a sole holder which the latter
6, um eine Querachse 6b in einem Lagerbock 16 schwenkbar gelagert ist. Auf dieser Querachse 6b ist auch eine eine Rastfeder 25 aufnehmende Federgabel 45 gelagert. Der Lagerbock 16 weist eine Vorderwand 16c auf, an welcher das Ende eines im Sohlenhalter 6 auf einer weiteren Querachse 48a gelagerten Rasthebels 48 anliegt. Dieser Rasthebel 48 wird an seiner Rückseite von einem Druckstück 49 beaufschlagt, das in Schlitzen der Federgabel 45 geführt und von der Rastfeder 25 beaufschlagt wird. Der Fersenhalter 2 ist mit einem Auslösehebel 91 versehen, der um die gleiche Achse 48a wie der Rasthebel 48 verschwenkt werden kann und zum willkürlichen Aussteigen dient.6, is pivotally mounted in a bearing block 16 about a transverse axis 6b. On this transverse axis 6b also a spring fork 45 receiving a detent spring 25 is mounted. The bearing block 16 has a front wall 16c, against which the end of a locking lever 48 which is mounted in the sole holder 6 on a further transverse axis 48a bears. This locking lever 48 is acted upon on its rear side by a pressure piece 49 which is guided in slots in the spring fork 45 and is acted upon by the detent spring 25. The heel holder 2 is provided with a release lever 91 which can be pivoted about the same axis 48a as the locking lever 48 and is used for arbitrary exiting.
Die Grundplatte 3 trägt an ihrem hinteren Ende eine horizontale Steuerlcurve 3a. Mit dieser wirkt, in noch näher zu beschreibender Weise, eine von einer Druckfeder 21 beaufschlagte Rolle 19 zusammen, welche, wie folgt , zur Steuerung der Verriegelung des Lagerbockes 16 dient.The base plate 3 carries a horizontal control curve 3a at its rear end. With this, in a manner to be described in more detail below, a roller 19 acted upon by a compression spring 21 interacts, which, as follows, serves to control the locking of the bearing block 16.
An ihrem hinteren Ende trägt die Sohlenplatte 8 eine Hochachse 61, an der die Basis 16a des Lagerbockes 16 gelagert ist. An das vordere Ende der Banach unten offene sis 16a ist eine /Gabel 16d angesetzt. Die Sohlenplatte 8 besitzt einerseits ein kreisbogenförmiges Langloch 71, das die Hochachse 61 als Mittelpunkt hat und in dem die Gabel 16d geführt ist, und anderseits einen in Richtung ihrer Längsachse verlaufenden Schlitz 72. Die von der Druckfeder 21 beaufschlagte Rolle 19 ist an einer vertikalen Achse 15 gelagert, die im Schlitz 72 der Sohlenplatte 8 geführt ist. Die Achse 15 ist in einem Winkeleisen 73 angeordnet, an dem das Ende der Druckfeder 21 anliegt, deren anderes Ende sich an einem nach unten ragenden Ansatz 8e der Sohlenplatte 8 abstützt. Die Achse 15 weist einen horizontal verlaufenden Fortsatz 15a auf, der zwischen den beiden Zinken der Gabel 16d in der Fahrtstellung der Skibindung geführt wird. Das vordere Ende des Lagerbockes 16 wird durch einen an die Sohlenplatte 8 angesetzten Vorsprung 75 gegen Abheben gesichert.At its rear end, the sole plate 8 carries a vertical axis 61, on which the base 16a of the bearing block 16 is mounted. A / fork 16d is attached to the front end of the sis 16a which is open at the bottom. The sole plate 8 has on the one hand an arcuate elongated hole 71, which has the vertical axis 61 as the center and in which the fork 16d is guided, and on the other hand a slot 72 running in the direction of its longitudinal axis. The roller 19 acted upon by the compression spring 21 is on a vertical axis 15 mounted, which is guided in the slot 72 of the sole plate 8. The axis 15 is arranged in an angle iron 73, on which the end of the compression spring 21 rests, the other end of which is supported on a downward projection 8e of the sole plate 8. The axis 15 has a horizontally extending extension 15a, which is guided between the two prongs of the fork 16d in the driving position of the ski binding. The front end of the bearing block 16 is secured against lifting off by a projection 75 attached to the sole plate 8.
In der Sohlenplatte 8 ist ferner ein zweites kreisbogenförmiges Langloch 76 ausgespart, dessen Mittelpunkt in der geometrischen Achse des Drehzapfens 4 liegt und in das ein aufgebogener Abschnitt 3d der Grundplatte 3 mit einer vertikalen Steuerkurve 77 ragt. Auf der vertikalen Steuerkurve 77 stützt sich eine Rolle 78 ab, die am Sohlenniederhalter 6 gelagert ist. Der Trittsporn 7 ist in bekannter Weise gelenkig ausgestaltet, um ein Hochschwenken des Sohlenhalters 6 auch bei einem Rückwärtsdrehsturz, wenn der Skifahrer mit dem Absatz des Skischuhs auf dem Trittsporn 7 steht, zu ermöglichen. In der Einstiegstellung ist der Trittsporn 7 am Sohlenhalter 6 abgestützt.In the sole plate 8 there is also a second circular elongated hole 76, the center of which lies in the geometric axis of the pivot pin 4 and into which a bent section 3d of the base plate 3 projects with a vertical control curve 77. A roller 78 is supported on the vertical cam 77 and is mounted on the sole hold-down device 6. The tread spur 7 is arranged hingedly in a known manner, ückwärtsdrehsturz a pivoting the sole holder 6 also with an R when the skier with the heel of the ski boot is on the tread spur 7, to enable. In the entry position, the step spur 7 is supported on the sole holder 6.
Bei einem Frontalsturz des Skiläufers gleitet das in Fig. 1 linke Ende des Rasthebels 48 entlang der Vorderwand 16c des Lagerbockes 16,bis der Skischuh freigegeben ist. Um einen wiedereinstieg des Skiläufers mit dem Skischuh zu ermöglichen, wird der Rasthebel 48 in der geöffneten Stellung des Fersenhalters 2 durch eine Rast festgehalten.In the event of a frontal fall of the skier, the left end of the locking lever 48 in FIG. 1 slides along the front wall 16c of the bearing block 16 until the ski boot is released. In order to enable the skier to re-enter with the ski boot, the locking lever 48 is held in the open position of the heel holder 2 by a latch.
Bei einem Drehsturz des Skiläufers wird die Sohlenplatte 8 um einen Drehzapfen 4 gegen die Kraft der Rastfeder 25, welche die Rolle 78 beaufschlagt, verdreht. Gleichzeitig rollt die Rolle 19 entlang der Steuerkurve 30, Die Rolle 78 hebt den Sohlenhal ter 6 so lange an, bis der Auslösepunkt des Sohlenhalters erreicht ist. Ist die Sohlenplatte 8 ausreichend ausgeschwenkt, so wird der Fortsatz 15a der Achse 15 aus dem Schlitz zwischen den beiden Zinken der Gabel 16d herausgezogen, wonach sich der Fersenhalter 2 um seine Hochachse 61 verschwenken kann. Dies hat aber eine seitliche Freigabe des Skischuhs zur Folge.When the skier falls, the sole plate 8 is rotated by a pivot 4 against the force of the detent spring 25, which acts on the roller 78. At the same time, roller 19 rolls along cam 30, roller 78 lifts the sole neck ter 6 until the trigger point of the sole holder is reached. If the sole plate 8 is swung out sufficiently, the extension 15a of the axis 15 is pulled out of the slot between the two prongs of the fork 16d, after which the heel holder 2 can pivot about its vertical axis 61. However, this means that the ski boot is released from the side.
Das in Fig. 4 dargestellte abgeänderte Detail der Skibindung nach den Fig. 1 - 3 unterscheidet sich von letzterer lediglich dadurch, daß die die Rolle 19' beaufschlagende Druckfeder 21' an ihrem von der Rolle entfernten Ende an einem Kolben 85 abgestützt ist , der in einem Schlitz 8'f der Sohlenplatte 8',gegen Verdrehen gesichert, geführt ist. An der von der Druckfeder 21' entfernten Seite des Kolbens 85 liegt eine Rändelschraube 87 mit ihrem Ende an, welche in eine Gewindebohrung des Ansatzes 8'e der Sohlenplatte 8' eingeschraubt ist.The modified detail of the ski binding according to FIGS. 1-3 shown in FIG. 4 differs from the latter only in that the compression spring 21 'acting on the roller 19' is supported at its end remote from the roller by a piston 85 which is in a slot 8'f of the sole plate 8 ', secured against rotation, is guided. On the side of the piston 85 remote from the compression spring 21 'there is a knurled screw 87 with its end, which is screwed into a threaded bore in the shoulder 8'e of the soleplate 8'.
Soll die Vorspannung der Druckfeder 21' verändert werden, so wird die Rändelschraube 87 im entsprechenden Drehsinn verdreht.If the pretension of the compression spring 21 'is to be changed, the knurled screw 87 is turned in the corresponding direction of rotation.
Die Erfindung ist nicht an das im vorstehenden beschriebene Ausführungsbeispiel gebunden. Vielmehr sind verschiedene Abänderungen desselben möglich, ohne den Rahmen der Erfindung zu verlassen. Beispielsweise könnte die zum Andrücken der Rolle an die Steuerkurve der Grundplatte bestimmte Druckfeder auch durch ein Tellerfeder-paket ersetzt werden. The invention is not tied to the exemplary embodiment described above. Rather, various modifications thereof are possible without leaving the scope of the invention. For example, the compression spring intended for pressing the roller onto the control curve of the base plate could also be replaced by a plate spring package.
