This press-on spring (5) is located in a spring cage (6) which is provided with a transverse wall (6a) and with a floor (6b). <??>In order to allow for a constant press-on pressure in this binding, the invention provides for the spring cage (6) to have at least two longitudinal ribs (6e) which extend on both sides of the floor (6b) and are designed to be of downward-convex shape in a section (6e1) of their longitudinal direction and to be resilient. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Sicherheitsskibin­dung nach dem Oberbegriff des Patentanspruches 1 oder 2.The invention relates to a safety ski binding according to the preamble of claim 1 or 2.

Eine derartige Skibindung ist bereits bekannt und in der AT-PS 387 151 beschrieben. Bei dieser Skibindung wird die Kompensation des Spiels zwischen dem Bindungskörper und der Führungsschiene dadurch erreicht, daß die Anpreßfe­der bei verrastetem Bindungskörper nach oben durchgebogen ist und mit dieser Auswölbung die Grundplatte der Bindung nach oben drückt. Dadurch erfüllt die Anpreßfeder zusätzlich die Funktion des Spielausgleiches, so daß bei dem Anpressen selbst im durchgebogenen Zustand der Feder ein Teil der Kraft unwirksam ist. Es ist daher erforderlich, die Anpreß­feder starker zu dimensionieren, um die für das Anpressen erforderliche Wirkung zu erlangen. Dadurch wird aber auch der Kraftaufwand für das Verstellen erhöht.Such a ski binding is already known and is described in AT-PS 387 151. With this ski binding, the compensation of the play between the binding body and the guide rail is achieved in that the pressure spring is bent upwards when the binding body is locked and with this bulge presses the base plate of the binding upwards. As a result, the pressure spring also fulfills the function of compensating for play, so that part of the force is ineffective when the pressure is applied even when the spring is bent. It is therefore necessary to dimension the pressure spring more strongly in order to achieve the effect required for the pressing. This also increases the effort required for the adjustment.

Die Erfindung stellt sich die Aufgabe, diesen Nachteil zu beseitigen und eine Skibindung zu schaffen, bei der eine Kompensation des Spiels zwischen dem Bindungskörper und der Führungsschiene unabhängig von der Anpreßfeder bewirkt wird.The object of the invention is to eliminate this disadvantage and to create a ski binding in which compensation for the play between the binding body and the guide rail is effected independently of the pressure spring.

Ausgehend von einer Skibindung gemäß dem Oberbegriff des Ansprüches 1 oder 2 wird diese Aufgabe erfindungsge­mäß durch die Merkmale des kennzeichnenden Teiles eines dieser Ansprüche gelöst. Dadurch, daß die Längsrippen fe­dernd ausgebildet sind bzw. daß an ihrer Unterseite ge­wölbte Blattfedern angesetzt sind, wird der auf das Bin­dungsgehäuse bzw. auf die Grundplatte ausgeübte Druck und somit der Spielausgleich unabhängig von der Anpreßfeder im­mer konstant gehalten.Starting from a ski binding according to the preamble of claim 1 or 2, this object is achieved according to the invention by the features of the characterizing part of one of these claims. Characterized in that the longitudinal ribs are resilient or that curved leaf springs are attached to their underside, the pressure exerted on the binding housing or on the base plate and thus the play compensation is always kept constant regardless of the pressure spring.

Durch den Gegenstand des Anspruches 3 wird der Kraftfluß von den federnden Abschnitten bzw. den Blattfedern in den Bin­dungskörper verbessert.The subject matter of claim 3 improves the flow of force from the resilient sections or the leaf springs into the binding body.

Durch die Maßnahmen der Ansprüche 4 und 5 wird eine spiel­freie Führung des Bindungskörpers auch quer zur Skilängsachse und parallel zur Skioberseite gewöhrleistet.The measures of claims 4 and 5 ensure play-free guidance of the binding body also transversely to the longitudinal axis of the ski and parallel to the top of the ski.

Durch das Merkmal des Anspruches 6 wird die Herstellung des Federkäfigs vereinfacht.The feature of claim 6 simplifies the manufacture of the spring cage.

Weitere Einzelheiten der Erfindung werden anhand der Zeichnung näher beschrieben. Die Fig. 1 bis 4 zeigen eine er­ste Ausführungsform einer erfindungsgemäßen Sicherheitsskibin­dung, wobei Fig. 1 eine teilweise geschnittene Seitenansicht und Fig. 2 ein Querschnitt nach der Linie II - II in Fig. 1 ist. Fig. 3 ist ein vertikaler Längsmittelschnitt nach der Li­nie III - III in Fig. 4 und Fig. 4 eine Draufsicht auf den Fe­derkäfig. Fig. 5 zeigt eine zweite Ausführungsform in einer Darstellung ähnlich Fig. 3.Further details of the invention will be described with reference to the drawing. 1 to 4 show a first embodiment of a safety ski binding according to the invention, FIG. 1 being a partially sectioned side view and FIG. 2 being a cross section along the line II-II in FIG. 1. Fig. 3 is a vertical longitudinal central section along the line III - III in Fig. 4 and Fig. 4 is a plan view of the spring cage. FIG. 5 shows a second embodiment in a representation similar to FIG. 3.

Die in den Fig. 1 und 2 dargestellte Sicherheitsskibin­dung besitzt eine nach oben offene, U-förmige Führungsschiene 2, welche mit ihrem Steg 2a auf der Oberseite eines Ski 1 mittels nicht dargestellter Schrauben befestigt ist und auf welcher ein Bindungskörper 3 mit seiner Grundplatte 3a in Längsrichtung des Ski 1 verschiebbar geführt ist. Die Grund­platte 3a ist in an sich bekannter Weise zur Anpassung der Bin­dung an unterschiedlich lange Skischuhe in der jeweils ge­wünschten Lage mittels einer Verstellraste 4 festlegbar. Die beiden Schenkel 2b der Führungsschiene 2 tragen nach innen vorspringende Flanschen 2c. Die Grundplatte 3a ist mit seit­lichen Führungsflanschen 3b versehen, welche - im montierten Zustand des Bindungskörpers 3, wie noch weiter beschrieben wird - gegen die Flanschen 2c der Führungsschiene 2 gedrückt werden.The safety ski binding shown in FIGS. 1 and 2 has an upwardly open, U-shaped guide rail 2, which is fastened with its web 2a on the top of a ski 1 by means of screws, not shown, and on which a binding body 3 with its base plate 3a in Longitudinal direction of the ski 1 is guided. The base plate 3 a can be fixed in a manner known per se for adapting the binding to ski boots of different lengths in the respectively desired position by means of an adjustment catch 4. The two legs 2b of the guide rail 2 carry inwardly projecting flanges 2c. The base plate 3a is provided with lateral guide flanges 3b, which - in the assembled state of the binding body 3, as will be described further - are pressed against the flanges 2c of the guide rail 2.

Die Grundplatte 3a besitzt zwei in einem Federkäfig 6 untergebrachte Anpreßfedern 5 und ist gegen die Kraft dieser Anpreßfedern 5 auf der Führungsschiene 2 von Skischuh weg verschiebbar. Die Anpreßfedern 5 sind zwischen einem Ansatz 3c der Grundplatte 3a und der hinteren Querwand 6a des Feder­ käfigs 6 eingespannt. Die Querwand 6a hat eine obere Begren­zungsfläche 6h. Der Federkäfig 6 ist aus Kunststoff herge­stellt und einstückig ausgebildet. Der Boden 6b des Federkä­figs 6 besteht aus drei parallel verlaufenden Längsrippen, nämlich aus einer mittleren Rippe 6c und aus zwei seitlichen Rippen 6e (s. Fig. 4). Zwischen den beiden seitlichen Rippen 6e und der mittleren Rippe 6c verlaufen Aussparungen 6d, wel­che sich in Skilängsrichtung erstrecken. Die beiden seitli­chen Längsrippen 6e sind, wie die Fig. 3 und 4 zeigen, in ei­nem Abschnitt 6e₁ ihrer Längserstreckung verjüngt, nach unten hin konvex gewölbt und somit federnd ausgebildet. Die Quer­wand 6a des Federkäfigs 6 ist gegenüber dessen Längsrippen 6e in zwei Abschnitten 6h₁ und 6h₂ erhöht, die die Begrenzungs­fläche 6h bilden. Zwischen den beiden Abschnitten 6h₁ und 6h₂ der Begrenzungsfläche 6h ist eine Nut 6i ausgespart. In dieser Nut 6i ist eine Führungsrippe 3e der Grundplatte 3a geführt. Außerdem sind an den Federkäfig 6 symmetrisch zur vertikalen Längsmittelebene zwei seitliche, in Draufsicht etwa T-förmige, jeweils mit zwei federnden Flanschen 6f versehene Ansätze 6g angeformt.The base plate 3 a has two pressure springs 5 accommodated in a spring cage 6 and can be displaced away from the ski boot on the guide rail 2 against the force of these pressure springs 5. The pressure springs 5 are between a shoulder 3c of the base plate 3a and the rear transverse wall 6a of the spring caged 6 clamped. The transverse wall 6a has an upper boundary surface 6h. The spring cage 6 is made of plastic and is formed in one piece. The bottom 6b of the spring cage 6 consists of three parallel longitudinal ribs, namely a central rib 6c and two lateral ribs 6e (see FIG. 4). Recesses 6d extend between the two lateral ribs 6e and the central rib 6c and extend in the longitudinal direction of the ski. The two lateral longitudinal ribs 6e are, as shown in FIGS. 3 and 4, tapered in a section 6e₁ of their longitudinal extent, convexly curved downward and thus resilient. The transverse wall 6a of the spring cage 6 is raised relative to its longitudinal ribs 6e in two sections 6h₁ and 6h₂, which form the boundary surface 6h. Between the two sections 6h₁ and 6h₂ of the boundary surface 6h, a groove 6i is recessed. A guide rib 3e of the base plate 3a is guided in this groove 6i. In addition, two lateral, approximately T-shaped approaches 6g, each provided with two resilient flanges 6f, are formed on the spring cage 6 symmetrically to the vertical longitudinal center plane.

Schiebt man die Grundplatte 3a des Bindungskörpers 3 mit ihrem Federkäfig 6 auf die Führungsschiene 2 auf, so werden die beiden seitlichen, nach unten hin konvexen federnden Rip­pen 6e des Federkäfigs gespannt. Dadurch legen sich die beiden Abschnitte 6h₁ und 6h₂ der erhöhten Begrenzungsfläche 6h der Querwand 6a an die Bodenfläche 3d der Grundplatte 3a an und drücken diese solange hoch, bis die Führungsflanschen 3b an den Flanschen 2c der Schiene 2 anliegen (s. Fig. 2). Der Feder­käfig 6 ist mittels der beiden Flanschen 6f seiner Ansätze 6g an den Schenkeln 2b der Führungsschiene 2 beim Verschieben der Grundplatte 3a gleitend geführt und relativ zur Führungsschie­ne 2 gleichzeitig zentriertIf you push the base plate 3a of the binding body 3 with its spring cage 6 onto the guide rail 2, the two lateral, downwardly convex resilient ribs 6e of the spring cage are tensioned. As a result, the two sections 6h₁ and 6h₂ of the raised boundary surface 6h of the transverse wall 6a lie against the bottom surface 3d of the base plate 3a and press them up until the guide flanges 3b rest against the flanges 2c of the rail 2 (see FIG. 2). The spring cage 6 is slidably guided by means of the two flanges 6f of its lugs 6g on the legs 2b of the guide rail 2 when the base plate 3a is moved and is centered relative to the guide rail 2 at the same time

Da die Grundplatte 3a - von der Seite gesehen - in Rich­rung zum Skischuh hin keilförmig verjüngt ist, nimmt der Bin­dungskörper 3 relativ zur Führungsschiene 2 - in Skilängsrich­ tung betrachtet - eine etwas geneigte Lage ein.Since the base plate 3a - seen from the side - tapers in a wedge shape in the direction of the ski boot, the binding body 3 takes up relative to the guide rail 2 - in the longitudinal direction of the ski considered - a somewhat inclined position.

Bei eingesetztem Skischuh wird der Bindungskörper 3 von den beiden Anpreßfedern 5 vorne nach oben und hinten nach un­ten gedrückt. Dabei werden infolge der geneigten vorderen Stirn­fläche des Ansatzes 3c die federnden Rippen 6e ihrem vorgespann­ten Zustand gegenüber etwas mehr gespannt. Die durch diese De­formation hervorgerufene Reibung ist jedoch gegenüber jener, welche durch die Reibungskräfte während des Verstellens des Bindungskörpers 3 bei Skidurchbiegungen entsteht, zu vernach­lässigen, so daß ein Ausgleich von Skidurchbiegungen praktisch ohne negative Einflüsse auf die beiden federnden Rippen 6e vor sich gehen kann.When the ski boot is inserted, the binding body 3 is pressed upwards by the two pressure springs 5 and downwards at the front. As a result of the inclined front end face of the projection 3c, the resilient ribs 6e are tensioned somewhat more than their pretensioned state. However, the friction caused by this deformation is negligible compared to that caused by the frictional forces during the adjustment of the binding body 3 during ski deflections, so that a compensation of ski deflections can take place practically without negative influences on the two resilient ribs 6e.

Bei der in Fig. 5 dargestellten zweiten Ausführungsform der Erfindung ist die Unterseite des Federkäfigs 6 eben ausge­bildet, und die beiden seitlichen Längsrippen 6e tragen je ei­ne nach unten konvex gewölbte Blattfeder 6e₂, die jeweils mit­tels zweier Nieten 6b₁ am Boden 6b des Federkäfigs 6 befestigt ist.In the second embodiment of the invention shown in Fig. 5, the underside of the spring cage 6 is flat, and the two lateral longitudinal ribs 6e each carry a downwardly convex leaf spring 6e₂, which is fastened by means of two rivets 6b₁ to the bottom 6b of the spring cage 6 .

Die Erfindung ist nicht auf die in der Zeichnung darge­stellten und im vorstehenden beschriebenen Ausführungsbeispiele beschränkt. Vielmehr sind verschiedene Abänderungen derselben möglich, ohne den Rahmen der Erfindung zu verlassen. Beispiels­weise kann anstelle von zwei Anpreßfedern im Federkäfig eine einzige Anpreßfeder untergebracht sein, die von den beiden Längsrippen flankiert ist, wobei dann die mittlere Längsrippe wegfällt.The invention is not limited to the exemplary embodiments shown in the drawing and described above. Rather, different modifications of the same are possible without leaving the scope of the invention. For example, instead of two pressure springs, a single pressure spring can be accommodated in the spring cage, which is flanked by the two longitudinal ribs, the central longitudinal rib then being eliminated.
