Description

Die Erfindung bezieht sich auf eine Skibremse, wie sie im ersten Teil des Patentanspruches 1 angegeben ist.The invention relates to a ski brake, as specified in the first part of claim 1.

Eine derartige Skibremse ist in der FR-A 2 430 244 in den Figuren 5 - 8 dargestellt und im Kontext beschrieben. Bei dieser Skibremse ist am Pedal ein mehrfach gekröpfter Drahtbremsbügel angelenkt, dessen die beiden Bremsschaufeln tragenden Schenkel beim Niedertreten des Pedals nach oben verschwenkt werden. Dies hat den Nachteil, daß während der Fahrt die Bremsschaufeln an herausragenden Steinen oder Ästen anschlagen können, was zu einer Behinderung der Fahrt führt.Such a ski brake is shown in FR-A 2 430 244 in FIGS. 5-8 and described in context. In this ski brake, a multi-cranked wire brake bracket is articulated on the pedal, the legs of which support the two brake blades are pivoted upwards when the pedal is depressed. This has the disadvantage that the brake vanes can strike protruding stones or branches during the journey, which leads to a hindrance to the journey.

Die Erfindung stellt sich die Aufgabe, diesen Nachteil zu beseitigen und eine Skibremse zu schaffen, bei der auf einfache Weise beim Niedertreten des Pedals ein Einziehen der Bremsschaufeln gegen die vertikale Längsmittelebene der Skibremse hin stattfindet.The object of the invention is to eliminate this disadvantage and to create a ski brake in which the brake blades are pulled in against the vertical longitudinal center plane of the ski brake in a simple manner when the pedal is depressed.

Ausgehend von einer Skibremse gemäß dem ersten Teil des Anspruches 1 wird diese Aufgabe erfindungsgemäß durch die Merkmale des zweiten Teiles dieses Anspruches gelöst. Dadurch, daß die Längsseitenwände des Gehäuses im Bereich der Längsschlitze einen konvexen oder abgewinkelten Verlauf haben, wird ein Einziehen der beiden Bremsschaufeln automatisch durchgeführt.Starting from a ski brake according to the first part of claim 1, this object is achieved according to the invention by the features of the second part of this claim. The fact that the longitudinal side walls of the housing have a convex or angled course in the region of the longitudinal slots means that the two brake blades are drawn in automatically.

An sich wäre es denkbar, die beiden Bremsdorne mit kugeligen Enden zu versehen, die in Kugelpfannen des Pedals gelagert sind. Dies würde aber die Fertigung erschweren. Durch die Maßnahme des Anspruches 2 wird auf einfache Weise eine schwenkbare Lagerung der Enden der beiden Bremsdorne ermöglicht.As such, it would be conceivable to provide the two brake mandrels with spherical ends, which are mounted in ball sockets of the pedal. However, this would make production more difficult. By the measure of claim 2 is a pivotable in a simple manner Allows storage of the ends of the two brake mandrels.

Die im Anspruch 3 angegebene erste Lösung hat den Vorteil, daß sich die beiden Bremsdorne innerhalb des Gehäuses abstützen und daß daher ihre Führungsflächen gegen Verunreinigungen geschützt sind.The first solution specified in claim 3 has the advantage that the two brake mandrels are supported within the housing and that their guide surfaces are therefore protected against contamination.

Der Anschlag für jeden Bremsdorn könnte an diesem durch Löten oder Schweissen befestigt werden. Diese Bauart hätte aber den Nachteil, daß bei einer Beschädigung oder bei einer Abnützung des Anschlages dieser nur schwer vom Bremsdorn entfernt werden könnte. Bei der im Anspruch 4 angegebenen Konstruktion hingegen kann der Anschlag, wenn er abgenützt sein sollte, jederzeit leicht entfernt und durch einen neuen Anschlag ersetzt werden.The stop for each brake mandrel could be attached to this by soldering or welding. This type of construction would have the disadvantage, however, that if the stop were damaged or worn, it would be difficult to remove it from the brake mandrel. In the construction specified in claim 4, however, the stop, if it should be worn, can be easily removed at any time and replaced by a new stop.

Die Maßnahme des Anspruches 5 hat den Vorteil, daß die Hülse unter Vorspannung am Bremsdorn anliegt und sich daher nicht so leicht ausleiern kann, wie eine Hülse, die mit Spiel auf den Bremsdorn aufgesetzt ist.The measure of claim 5 has the advantage that the sleeve rests under prestress on the brake mandrel and therefore cannot wear out as easily as a sleeve that is placed on the brake mandrel with play.

Durch den Gegenstand des Anspruches 6 wird die Anlage des Anschlages an der inneren Begrenzungsfläche der Längsseitenwand in jeder Stellung des Pedals sichergestellt.By the subject of claim 6, the abutment of the stop on the inner boundary surface of the longitudinal side wall is ensured in any position of the pedal.

Das Merkmal des Anspruches 7 verbessert die Anlage des Anschlages an der Längsseitenwand des Gehäuses, so daß eine Punktberührung vermieden wird.The feature of claim 7 improves the abutment of the stop on the longitudinal side wall of the housing, so that point contact is avoided.

Die im Anspruch 8 angegebene zweite Lösung hat den Vorteil, daß bei ihr der Anschlag in Form einer Scheibe ausgebildet werden kann und daher einfacher herzustellen ist, als die im Anspruch 4 gekennzeichnet Hülse.The second solution specified in claim 8 has the advantage that the stop can be designed in the form of a disk and is therefore easier to manufacture than the sleeve characterized in claim 4.

Schließlich ermöglicht es die Maßnahme des An spruches 9, daß die beiden Anschläge in jeder Lage des Pedals zuverlässig an der äußeren Begrenzungsfläche der Längsseitenwände anliegen.Finally, the measure of the contractor makes it possible Proverb 9 that the two stops in any position of the pedal reliably rest on the outer boundary surface of the longitudinal side walls.

In der Zeichnung sind zwei beispielsweise Ausführungsformen der erfindungsgemäßen Skibremse dargestellt. Fig. 1 ist ein Schnitt durch die in der Bremsstellung befindlichen erste Ausführungsform nach der Linie I - I in Fig. 2 und Fig. 2 eine dazugehörige Draufsicht. In den Fig. 3 und 4 sind analoge Darstellungen der in der Fahrtstellung befindlichen Skibremse wiedergegeben, wobei Fig. 3 ein Schnitt nach der Linie III - III in Fig. 4 ist. Fig. 5 zeigt ein Detail einer Variante zur Skibremse nach Fig. 1. Schließlich ist in Fig. 6 eine zweite Ausführungsform einer Skibremse in Draufsicht dargestellt.Two exemplary embodiments of the ski brake according to the invention are shown in the drawing. Fig. 1 is a section through the first embodiment in the braking position along the line I - I in Fig. 2 and Fig. 2 is an associated plan view. 3 and 4, analog representations of the ski brake in the driving position are shown, FIG. 3 being a section along the line III-III in FIG. 4. FIG. 5 shows a detail of a variant of the ski brake according to FIG. 1. Finally, a second embodiment of a ski brake is shown in plan view in FIG. 6.

In den Fig. 1 und 2 ist die Skibremse in einer Gesamtheit mit 1 bezeichnet. Sie besitzt ein als Grundplatte dienendes Gehäuse 2, das auf der Skioberseite mittels nicht dargestellter Schrauben befestigt ist. Selbstverständlich kann das Gehäuse 2 von einem Skibindungsteil niedergehalten, in diesen integriert, an einem Skibindungsteil geführt oder an der Skioberseite auch angeklebt sein. Die Breite des Gehäuses 2 entpricht zumindest angenähert der Breite des Ski, der in der Zeichnung nicht dargestellt ist. Im Gehäuse 2 ist ein Pedal 3 auf einer Achse 4 schwenkbar gelagert.1 and 2, the ski brake is designated 1 in its entirety. It has a housing 2 serving as a base plate, which is fastened to the top of the ski by means of screws, not shown. Of course, the housing 2 can be held down by a ski binding part, integrated into this, guided on a ski binding part or also glued to the top of the ski. The width of the housing 2 corresponds at least approximately to the width of the ski, which is not shown in the drawing. In the housing 2, a pedal 3 is pivotally mounted on an axis 4.

Am freien Ende des Pedals 3 sind zwei Bremsdorne 5 aus Stahldraht mit ihren oberen Enden gelagert. Diese Bremsdorne 5 sind mehrfach abgewinkelt und besitzen einen Abschnitt 5a, mit dem sie im Pedal 3 gelagert sind, einen an diesen anschließenden Abschnitt 5b, einen zum Abschnitt 5a parallelen Abschnitt 5c, welcher die Schwenkachse des Bremsdornes 5 bildet, und einen Abschnitt 5d, der eine nicht dargestellte Bremsschaufel trägt. Zur Lagerung und Führung des Abschnittes 5c jedes Bremsdornes 5 sind in den Längsseitenwänden des Gehäuses 2 Längsschlitze 2a ausgespart, welche parallel zur Basis des Gehäuses 2 verlaufen.At the free end of the pedal 3, two steel wire brake mandrels 5 are supported with their upper ends. These brake mandrels 5 are angled several times and have a section 5a with which they are mounted in the pedal 3, a section adjoining this 5b, a section 5c parallel to section 5a, which forms the pivot axis of the brake mandrel 5, and a section 5d, which carries a brake blade (not shown). For storing and guiding the section 5c of each brake mandrel 5, longitudinal slots 2a are cut out in the longitudinal side walls of the housing 2 and run parallel to the base of the housing 2.

Das Pedal 3 steht unter dem Einfluß einer Schenkelfeder 6, welche auf der Achse 4 angeordnet ist und welche bestrebt ist, das Pedal 3 nach oben zu schwenken. Zur Lagerung der Abschnitte 5a der Bremsdorne 5 ist im Bereich des freien Endes des Pedals 3 eine Bohrung 3a ausgespart, welche im Bereich ihrer beiden Enden zwar in Draufsicht kreisförmig ist, sich gegen die vertikale Längsmittelebene des Gehäuses 2 hin jedoch in ihrer Parallelebene zur Pedalunterseite keilförmig erweitert, so daß eine Schwenkbewegung der Abschnitte 5 a der Bremsdorne 5 möglich ist.The pedal 3 is under the influence of a leg spring 6, which is arranged on the axis 4 and which tends to pivot the pedal 3 upwards. To support the sections 5a of the brake mandrels 5, a bore 3a is cut out in the area of the free end of the pedal 3, which hole is in the area of its two ends is circular in plan view, but widened in a wedge shape towards the vertical longitudinal center plane of the housing 2 in its parallel plane to the underside of the pedal, so that a pivoting movement of the sections 5 a of the brake mandrels 5 is possible.

Die beiden Bremsdorne 5 stehen unter dem Einfluß einer Druckfeder 7, welche bestrebt ist, die Bremsdorne nach außen zu drücken. Um den weg der beiden Bremsdorne 5 von der vertikalen Längsmittelebene des Gehäuses 2 weg zu begrenzen, ist auf jeden Bremsdorn 5 eine Hülse 8 aufgesetzt, die auf der Innenseite der zugehörigen Seitenwand des Gehäuses 2 gleitet.The two brake mandrels 5 are under the influence of a compression spring 7, which strives to push the brake mandrels outwards. In order to limit the path of the two brake mandrels 5 away from the vertical longitudinal center plane of the housing 2, a sleeve 8 is placed on each brake mandrel 5, which slides on the inside of the associated side wall of the housing 2.

Diese Hülse 8 ist mit einem Schlitz 8a versehen, der sich über die ganze Länge der Hülse erstreckt und zum Aufsetzen der Hülse auf den Abschnitt 5 c des Bremsdornes 5 dient. Vom einen Ende der Hülse 8 weg erstreckt sich eine Nut, die zur Aufnahme des Abschnittes 5 b des Bremsdornes 5 bestimmt ist. Das der Nut gegenüberliegende Ende der Hülse 8 ist konisch abgefast oder zylindrisch gekrümmt, um das Gleiten der Hülse 8 an der Längsseitenwand des Gehäuses 2 zu erleichtern. Im Bereich der beiden Längsschlitze 2a sind die beiden Längsseitenwände des Gehäuses 2 bogenförmig gekrümmt oder abgewinkelt ausgebildet.This sleeve 8 is provided with a slot 8 a, which extends over the entire length of the sleeve and is used to place the sleeve on the section 5 c of the brake mandrel 5. A groove extends from one end of the sleeve 8 and is intended for receiving the section 5 b of the brake mandrel 5. The end of the sleeve 8 opposite the groove is conically chamfered or cylindrically curved in order to facilitate the sliding of the sleeve 8 on the longitudinal side wall of the housing 2. In the area of the two longitudinal slots 2a, the two longitudinal side walls of the housing 2 are curved or angled in an arc.

In der Bremsstellung nimmt die Skibremse 1 die in den Fig. 1 und 2 dargestellte Lage ein. Das Pedal 3 ist unter dem Einfluß der Schenkelfeder 6 aufgerichtet, und die Abschnitte 5 c der beiden Bremsdorne 5 befinden sich an den linken Enden der Längsschlitze 2 a . Der Abschnitt 5 a jedes Bremsdornes 5 hingegen liegt an der rechten Begrenzung der Bohrung 3 a an.In the braking position, the ski brake 1 assumes the position shown in FIGS. 1 and 2. The pedal 3 is erected under the influence of the leg spring 6, and the sections 5 c of the two brake mandrels 5 are located on the left ends of the longitudinal slots 2 a. The section 5 a of each brake mandrel 5, however, rests on the right boundary of the bore 3 a.

Wird nun vom Skiläufer mit dem Skischuh auf das Pedal 3 ein Druck ausgeübt, so verschwenkt dieses gegen die Kraft der Schenkelfeder 6 im Uhrzeigersinn um die Achse 4, bis es parallel zur Basis des Gehäuses 2 liegt (s. Fig. 3 ). Die Schenkelfeder 6 wird dabei gespannt. Gleichzeitig wird der Abschnitt 5 c jedes Bremsdornes 5 im zugehörigen Längsschlitz 2 a nach rechts verschoben. Da sich jedoch die Längsschlitze 2a in den bogenförmig gekrümmten bzw. abgewinkelten Abschnitten der Längsseitenwände des Gehäuses 2 befinden, findet neben der Verschiebung der Bremsdorne 5 nach rechts und der Verdrehung derselben um die Abschnitte 5 c gleichzeitig auch eine Verschwenkung der Abschnitte 5 d und damit der Bremsdorne zur vertikalen Längsmittelebene des Gehäuses 2 hin statt, und die Feder 7 wird dabei zusammen gedrückt (vgl. Fig. 4 ). Dabei erfahren auch die Abschnitte 5 a der Bremsdorne 5 in der Bohrung 3 a eine Verschwenkung, indem sie sich an die linke Begrenzungswand dieser Bohrung anlegen. Die eingeschwenkte Lage der Abschnitte 5 d der Bremsdorne 5 ist damit erreicht.If a pressure is now exerted on the pedal 3 by the skier with the ski boot, it pivots clockwise about the axis 4 against the force of the leg spring 6 until it lies parallel to the base of the housing 2 (see FIG. 3). The leg spring 6 is tensioned. At the same time, section 5 c of each brake mandrel 5 is shifted to the right in the associated longitudinal slot 2 a. However, since the longitudinal slots 2a are located in the arcuately curved or angled sections of the longitudinal side walls of the housing 2, in addition to the displacement of the brake mandrels 5 to the right and the rotation thereof by the sections 5c, there is also a pivoting of the sections 5d and thus the Brake mandrels to the vertical longitudinal center plane of the housing 2 instead, and the spring 7 is pressed together (see. Fig. 4). The sections 5 a of the brake mandrels 5 also experience a pivoting in the bore 3 a by laying against the left boundary wall of this bore. The pivoted position of the sections 5 d of the brake mandrels 5 is thus achieved.

Die in Fig. 5 dargestellte Hülse , 8′ unterscheidet sich von der in den Fig. 1 bis 4 wiedergegebenen Hülse 8 lediglich dadurch, daß sie aus federndem Material hergestellt ist. Aus diesem Grunde ist der Schlitz 8′a schmäler als der Durchmesser des Abschnittes 5 c des Bremsdornes 5 . Die Hülse 8′ liegt daher unter Spannung am Abschnitt 5 c an. Die Nut 8 b besitzt eine Breite, welche dem Durchmesser des Abschnittes 5 b des Bremsdornes 5 entspricht.The sleeve shown in Fig. 5, 8 'differs from that shown in Figs. 1 to 4 sleeve 8 only in that it is made of resilient material. For this reason, the slot 8'a is narrower than the diameter of section 5 c of the brake mandrel 5th The sleeve 8 'is therefore under tension on section 5 c. The groove 8 b has a width which corresponds to the diameter of the section 5 b of the brake mandrel 5.

Die in Fig. 6 dargestellte Skibremse 1′ ist der ersten sehr ähnlich. Sie unterscheidet sich von dieser lediglich dadurch, daß anstelle von Hülsen Anschläge 10 in Form von Scheiben auf den Abschnitten 5 ′c der Bremsdorne 5′ angeordnet sind, welche Anschläge an der Außenseite der Seitenwände des Gehäuses 2′ gleiten. Weiters ist zwischen den beiden Bremsdornen 5 ′ anstelle einer Druckfeder eine Zugfeder 11 angeordnet.The ski brake 1 shown in Fig. 6 'is very similar to the first. It differs from this only in that instead of sleeves stops 10 in the form of disks on the sections 5 'c of the brake mandrels 5' are arranged, which stops on the outside of the side walls of the housing 2 'slide. Furthermore, a tension spring 11 is arranged between the two brake mandrels 5 'instead of a compression spring.

Die Arbeitsweise der Skibremse 1′ entspricht in der Hauptsache der der zuvor beschriebenen Ausführungsform.The operation of the ski brake 1 'corresponds mainly to that of the embodiment described above.

Die Erfindung ist keineswegs an die in der Zeichnung dargestellten und im vorstehenden beschriebenen Ausführungsbeispiele gebunden. Vielmehr sind verschiedene Abänderungen derselben möglich, ohne den Rahmen der Erfindung zu verlassen. Beispielsweise müssen bei beiden Ausführungen die zur Lagerung in den Langlöchern dienenden Abschnitte der Bremsdorne nicht unmittelbar in den Längsschlitzen gelagert sein. Sie können vielmehr auch in Gleitsteinen gelagert werden, die in entsprechenden Führungsbahnen in den Langlöchern der Seitenwände des Gehäuses geführt sind.The invention is in no way tied 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, in both versions, the sections of the brake mandrels used for storage in the elongated holes do not have to be mounted directly in the longitudinal slots. Rather, they can also be stored in sliding blocks which are guided in corresponding guideways in the elongated holes in the side walls of the housing.
