Abstract

The invention relates to a ski brake with two brake arms arranged on both sides of the ski, which are respectively formed with an adjoining pivot-shaft part and a holding arm made of an essentially Z-shaped round wire piece. In this connection, the pivot-shaft parts are aligned approximately at right angles to the longitudinal axis of the ski and approximately coaxially with one another and mounted on the upper side of the ski by means of a holding plate. Furthermore, the free ends of the holding arms are angled towards one another and serve as a bearing for a pedal which can be operated by the ski boot and which forms an arm of a toggle lever, the second arm of which is mounted firmly on the ski at a distance from the pivot-shaft parts and the toggle joint of which is formed by a pivot and slide bearing, the brake arms being pivotable, against elastic force, out of the braking position into a position parallel to the ski and, in relation to the ends of the holding arms, pivotable in towards the longitudinal axis of the ski into a position of readiness, and the pivoting-in taking place by means of a relative movement of the pedal in relation to the holding arms. To achieve the aim of developing and designing such a ski brake in such a manner that, while maintaining its specific advantages, a simplification of the pedal can be achieved, which on the one hand permits more economical manufacture and on the other hand increases the operational safety of the ski brake, the pedal (9, 29) has at least one operating element (15, 34) which is provided to interact with the angled sections (8, 28) of the holding arms (6, 26). <IMAGE>

Description

Die vorliegende Erfindung bezieht sich auf Skibremsen gemäß dem Oberbegriff der Patentansprüche 1 bzw. 2.The present invention relates to ski brakes according to the preamble of claims 1 and 2, respectively.

Bei diesen vorbekannten Skibremsen, die in ihrem grundsätzlichen Aufbau in der FR-A-2 516 392 beschrieben sind, erfolgt das Einschwenken in die Bereitschaftstellung dadurch, daß beim Durchtreten des Kniegelenks, wenn die Bremsarme sich in skiparalleler Lage befinden, das Pedal mit auf der Unterseite vorgesehenen Rampen, die die Haltearme bildenden Teile der Rundradstücke so beeinflußt, daß diese zur Skilängsachse hin bewegt werden.In these known ski brakes, which are described in their basic structure in FR-A-2 516 392, the swiveling into the standby position takes place in that when the knee joint is passed, when the brake arms are in a parallel position with the ski, the pedal is on the Underside provided ramps, which influences the parts of the circular wheel pieces forming the holding arms so that they are moved towards the longitudinal axis of the ski.

Gegenüber weiter bekannten aber gattungsfremden Skibremsen weisen die vorerwähnten einen wesentlichen Vorteil auf, der darin besteht, daß das Pedal beim Durchtreten des Kniegelenks praktisch nur eine Schwenkbewegung ausführt, d.h. sich gegenüber der Oberfläche des Ski in dessen Längsrichtung bewegt. Hierdurch werden Reibungswiderstände insbesondere zwischen Pedal und Skischuh sehr gering gehalten.Compared to other well-known but non-generic ski brakes, the aforementioned have an essential advantage, which is that the pedal practically only performs a pivoting movement when the knee joint is passed, i.e. moves in the longitudinal direction of the surface of the ski. This keeps frictional resistance, especially between the pedal and the ski boot, very low.

Zweck der vorliegenden Erfindung ist es, die gattungsgemäßen Skibremsen konstruktiv so weiterzubilden und zu gestalten, daß unter Beibehaltung ihrer spezifischen Vorteile sich eine Vereinfachung des Pedals erreichen läßt, die einerseits eine billigere Herstellung gestattet und andererseits die Funktionssicherheit der Skibremse erhöht.The purpose of the present invention is to further develop and design the generic ski brakes in such a way that, while maintaining their specific advantages, a simplification of the pedal can be achieved, which on the one hand allows cheaper production and on the other hand increases the functional reliability of the ski brake.

Erfindungsgemäß ist dies durch die kennzeichnenden Merkmale des Patentanspruchs 1 bzw. 2 erreicht. Dabei kann bei der ersten Ausführungsform als Betätigungselement eine Fläche im Pedal dienen, die sich wenigstens annähernd rechtwinkelig zur Trittfläche und parallel zur Anlenkachse des Pedals erstreckt. In konstruktiver Ausgestaltung dieses Erfindungsgedankens hat es sich als vorteilhaft erwiesen, daß die freien Enden der Abwinkelungen der Haltearme auf ihrer zur Schwenkachse der Bremse hin gerichteten Seite nockenartig erweitert sind.According to the invention, this is achieved by the characterizing features of patent claim 1 or 2. In the first embodiment, a surface in the pedal can be used as the actuating element that extends at least approximately at right angles to the tread surface and parallel to the articulation axis of the pedal. In a constructive embodiment of this inventive concept, it has proven to be advantageous that the free ends of the bends Holding arms are extended cam-like on their side facing the pivot axis of the brake.

Dagegen sieht eine zweite Ausführungsform der Erfindung als Betätigungselement einen Schieber vor, der im Pedal wenigstens annähernd parallel zu dessen Trittfläche gelagert und von dem zweiten Arm des Kniehebels beeinflußbar ist.In contrast, a second embodiment of the invention provides a slide as an actuating element, which is mounted in the pedal at least approximately parallel to its tread surface and can be influenced by the second arm of the toggle lever.

Zweckmäßig sind die freien Enden der Abwinkelungen der Haltearme von einer Spreizfeder beaufschlagt. Vorzugsweise ist als Spreizfeder eine beidendig im Pedal abgestützte Blattfeder vorgesehen.The free ends of the bends of the holding arms are expediently acted upon by an expansion spring. Preferably, a leaf spring supported on both ends in the pedal is provided as the spreading spring.

Die in den Figuren 1 bis 3 dargestellte Skibremse besitzt eine Grundplatte 1, mit der sie beispielsweise auf einen Ski 2 geschraubt ist. Die Grundplatte kann in an sich bekannter Weise entsprechend verlängert sein und einen Bindungsteil einer Sicherheitsskibindung tragen. Insbesondere in diesem Fall ist die Grundplatte zweckmäßig nicht unmittelbar sondern über eine Führungsplatte mit dem Ski verbunden, an der sie in Skilängsrichtung verschiebbar gehalten ist.The ski brake shown in FIGS. 1 to 3 has a base plate 1 with which it is screwed onto a ski 2, for example. The base plate can be correspondingly extended in a manner known per se and can carry a binding part of a safety ski binding. In this case in particular, the base plate is expediently not connected to the ski directly but via a guide plate, on which it is held so as to be displaceable in the longitudinal direction of the ski.

Die Skibremse umfaßt zwei beidseitig des Ski 2 angeordnete Bremsbügel 3,4 (siehe insbesondere Fig. 3), die aus Runddrahtstücken gebildet und im wesentlichen Z-förmig gestaltet sind. Die Stege 5 sind auf der Grundplatte 1 gelagert und bilden Schwenkachsenteile, die etwa rechtwinkelig zur Längsachse des Ski und etwa koaxial zueinander verlaufen. Die in Bezug auf die Darstellungen linken Schenkel 6 bilden die Haltearme, während die rechten Schenkel 7 die Bremsarme bilden.The ski brake comprises two brake brackets 3, 4 arranged on both sides of the ski 2 (see in particular FIG. 3), which are formed from round wire pieces and are essentially Z-shaped. The webs 5 are mounted on the base plate 1 and form swivel axis parts which run approximately at right angles to the longitudinal axis of the ski and approximately coaxially with one another. The left leg 6 in relation to the illustrations form the holding arms, while the right leg 7 form the brake arms.

Die freien Enden der Haltearme 6 sind aufeinander zu abgewinkelt und bilden Lagerzapfen 8 für ein Pedal 9, das von einem nicht dargestellten Skischuh zu betätigen ist. Dieses Pedal bildet einen Arm eines Kniehebels, dessen zweiter Arm 10 mit Abstand von den Schwenkachsenteilen mittels eines Lagerzapfens 11 an der Grundplatte 1 gelagert ist. Das Kniegelenk ist durch einen Achszapfen 12 gebildet, der im Pedal schwenkbar und verschiebbar gelagert ist, wozu er mit seinen freien Enden in Führungsnuten 13 des Pedals eingreift.The free ends of the holding arms 6 are angled toward one another and form bearing journals 8 for a pedal 9 which can be actuated by a ski boot, not shown. This pedal forms an arm of a toggle lever, the second arm 10 of which is mounted on the base plate 1 at a distance from the swivel axis parts by means of a bearing pin 11. The knee joint is formed by an axle pin 12 which is pivotally and displaceably mounted in the pedal, for which purpose it engages with its free ends in guide grooves 13 of the pedal.

Der Kniehebelarm 10 steht unter dem Einfluß einer nicht dargestellten Feder, die ihn in Bezug auf die Darstellungen im Uhrzeigersinn belastet und damit die Skibremse in ihrer Bremsstellung zu halten trachtet. In bekannter Weise kann diese Feder als gewundene Biegefeder ausgebildet und auf dem Lagerzapfen 11 gelagert sein.The toggle lever arm 10 is under the influence of a spring, not shown, which loads it clockwise in relation to the representations and thus the ski brake in to keep their braking position. In a known manner, this spring can be designed as a spiral spiral spring and can be mounted on the journal 11.

Die als Lagerzapfen 8 für das Pedal 9 dienenden Abwinkelungen der Haltearme 6 weisen jeweils eine nockenartige Erweiterung 14 auf (siehe insbesonder Fig. 2). Diese dienen zum Zusammenwirken mit einem Betätigungselement, das im vorliegenden Fall von einer Fläche 15 eines Druckstücks 16 im Pedal 9 gebildet ist, die sich wenigstens annähernd rechtwinkelig zur Trittfläche und parallel zur Anlenkachse des Pedals erstreckt. Die freien Enden der Abwinkelungen 8 sind von einer beidendig im Pedal 9 abgestützten Blattfeder 17 beaufschlagt.The angled portions of the holding arms 6 serving as bearing pins 8 for the pedal 9 each have a cam-like extension 14 (see in particular FIG. 2). These serve to interact with an actuating element, which in the present case is formed by a surface 15 of a pressure piece 16 in the pedal 9, which extends at least approximately at right angles to the tread surface and parallel to the articulation axis of the pedal. The free ends of the bends 8 are acted upon by a leaf spring 17 supported at both ends in the pedal 9.

Die Position der Skibremse nach Figur 1 ist eine Übergangsposition, die beim Einsetzen des nicht dargestellten Skischuhs in die ebenfalls nicht dargestellte Sicherheits-Skibindung erreicht wird. Die Skibremse ist aus ihrer Bremsstellung entgegen der den Kniehebelarm 10 belastenden Federkraft in Bezug auf die Darstellung entgegen dem Uhrzeigersinn geschwenkt worden. Beim weiteren Niedertreten des Pedals in die in Figur 2 gezeigte Position, der Bereitschaftsstellung, erfolgt das Einschwenken der Bremsbügel 3,4 entsprechend der Darstellung in der unteren Hälfte der Figur 3. Dieses Einschwenken geschieht durch Einwirkung des mit der Fläche 15 der Erweiterung 14 der Abwinkelungen 8 anliegenden Druckstücks 16. Dieses Einschwenken erfolgt entgegen der Kraft der Blattfeder 17, so daß diese ein Spreizen der Bremsbügel 3,4 bewirkt, wenn sich die Bremse nach Fortfall der Belastung des Pedals 9 aufstellt.The position of the ski brake according to FIG. 1 is a transition position which is achieved when the ski boot, not shown, is inserted into the safety ski binding, also not shown. The ski brake has been pivoted from its braking position counter to the spring force loading the toggle lever arm 10 in a counterclockwise direction with respect to the illustration. When the pedal is depressed further into the position shown in FIG. 2, the standby position, the brake brackets 3, 4 swivel in as shown in the lower half of FIG. 3. This swiveling takes place by the action of the surface 15 of the extension 14 of the bends 8 adjacent thrust piece 16. This pivoting takes place against the force of the leaf spring 17, so that this causes the brake bracket 3, 4 to spread when the brake is raised after the load on the pedal 9 has ceased.

Die Skibremse nach den Figuren 4 bis 6 entspricht in ihrem grundsätzlichen Aufbau der Ausführung nach den Figuren 1 bis 3. So ist wiederum eine Grundplatte 21 vorhanden, über die die Skibremse auf dem Ski 22 gehalten ist. Die beiden Bremsbügel sind mit 23 und 24 bezeichnet und umfassen jeweils einen Steg 25, einen Haltearm 26 und einen Bremsarm 27. Abwinkelungen der Haltearme 26 bilden wiederum Lagerzapfen 28 für ein Pedal 29.The basic structure of the ski brake according to FIGS. 4 to 6 corresponds to that of FIGS. 1 to 3. Thus, a base plate 21 is again provided, by means of which the ski brake is held on the ski 22. The two brake brackets are designated by 23 and 24 and each comprise a web 25, a holding arm 26 and a braking arm 27. Angles of the holding arms 26 in turn form bearing pins 28 for a pedal 29.

Zusammen mit einem Arm 30 bildet das Pedal 29 einen Kniehebel, dessen Kniegelenk durch einen Achszapfen 32 gebildet ist,der mit seinen freien Enden in Führungsnuten 33 des Pedals eingreift. Wie bei der ersten Ausführung steht auch hier der Arm 30 unter dem Einfluß einer Aufstellfeder.Together with an arm 30, the pedal 29 forms a toggle lever, the knee joint of which is formed by an axle journal 32 which engages with its free ends in guide grooves 33 of the pedal. As in the first embodiment, the arm 30 is also under the influence of a spring.

Im Gegensatz zur ersten Ausführung ist hier als Betätigungselement ein Schieber 34 vorgesehen, der im Pedal 29 wenigstens annähernd parallel zu dessen Trittfläche verschiebbar gelagert und von dem Arm 30 beeinflußbar ist. Der Schieber wirkt auf die freien Enden der Abwinkslungen 28, die andererseits wiederum von einer beidendig im Pedal 29 abgestützten Blattfeder 37 beaufschlagt werden.In contrast to the first embodiment, a slide 34 is provided here as the actuating element, which is mounted in the pedal 29 so as to be displaceable at least approximately parallel to its tread surface and can be influenced by the arm 30. The slide acts on the free ends of the angled loops 28, which in turn are acted upon by a leaf spring 37 supported at both ends in the pedal 29.

Beim Übergang aus der Zwischenposition nach Figur 4 in die Bereitschaftsstellung nach Figur 5 erfolgt eine Verschiebung des Achszapfens 32 in den Führungsnuten 33 des Pedals 29. Hierbei drückt der Arm 30 mit seinem inneren Ende gegen den Schieber 34 und bewirkt dessen Verschiebung im Pedal. Der an den freien Enden der Abwinkelungen 28 angreifende Schieber bewirkt dadurch das Einschwenken der Bremsbügel 23, 24, wie ein Vergleich der beiden Hälften der Figur 6 erkennen läßt. Das Spreizen der Bremsbügel wird wiederum durch die Blattfeder 37 bewirkt, wenn sich die Bremse nach Fortfall der Belastung des Pedals 29 aufstellt.During the transition from the intermediate position according to FIG. 4 to the ready position according to FIG. 5, the axle journal 32 is displaced in the guide grooves 33 of the pedal 29. Here, the arm 30 presses with its inner end against the slide 34 and causes it to be displaced in the pedal. The slider acting on the free ends of the bends 28 thereby causes the brake brackets 23, 24 to pivot in as a Comparison of the two halves of Figure 6 reveals. The spreading of the brake bracket is in turn effected by the leaf spring 37 when the brake is raised after the load on the pedal 29 has ceased.
