Abstract

For the mutually independent release of two foot support elements which are respectively provided on the outside with locking pins and on the inside with locking devices, a compressionally stable but otherwise movable connection - in the particular case two hydraulic pressure cylinders which are connected by means of a line - is arranged on the snowboard. It is now possible to get into the locking pistons of the connection with the foot support elements which are then respectively snapped into an automatic binding device on their outside. If one automatic device is then released in the event of a fall, the locking piston of the other foot support element loses counterpressure, and the virtually simultaneous release of both foot support elements is guaranteed. In practical application, conventional ski bindings can be used as automatic binding devices. The foot support elements serve likewise to receive proven boot-holding systems. <IMAGE>

Description

Die Erfindung betrifft ein Auslösesystem für ein Snowboard nach dem Oberbegriff des Anspruches 1.The invention relates to a release system for a snowboard according to the preamble of claim 1.

Auslösesysteme sind bisher nur für den Gebrauch auf Skiern bekannt. Es ist bekannt, daß es für Snowboards Bindungen als Schnallen oder Bügel-Schuhhaltesysteme gibt. (Zeitschrift "Snowboard" Nr. 2, Ausgabe November 1988, Seite 28 und Seite 34 bis 37).Release systems are so far only known for use on skis. It is known that there are bindings for snowboards as buckles or strap-on shoe holding systems. (Magazine "Snowboard" No. 2, November 1988 edition, page 28 and pages 34 to 37).

Die herkömmlichen Bindungssysteme verbinden jedoch den quer auf dem Board stehenden Fahrer fest mit dem Board. Dies birgt insbesondere bei höheren Geschwindigkeiten erhebliche Sturzverletzungsgefahren vor allem durch auftretende Torsionskräfte bei Drehstürzen.However, the conventional binding systems firmly connect the driver standing across the board to the board. This entails considerable risk of falling injuries, especially at higher speeds, especially as a result of torsional forces that occur during turning falls.

Der Erfindung liegt die Aufgabe zu Grunde, die Trennung des Fahrers vom Board im Sturzfalle mit beiden Füßen zu gewährleisten, im Hinblick darauf, daß die Füße in Abhängigkeit der Bindungen voneinander, einzeln auslösen.
Dies hat erhebliche Bedeutung, da ein verbleibender Fuß auf dem Board die Gefahr schwerster Verletzungen in sich birgt.The invention is based on the object of ensuring the separation of the driver from the board in the event of a fall with both feet , in view of the fact that the feet trigger individually depending on the bindings.
This is of considerable importance since a foot remaining on the board carries the risk of serious injuries.

Diese Aufgabe wird bei einer gattungsgemäßen Einrichtung durch die Merkmale des Anspruches 1. gelöst.This object is achieved in a generic device by the features of claim 1.

Um eine solche Auslösung auch in Hinblick auf Verwindungsstabilität zu gewährleisten, sind in einem Ausführungsbeispiel Druckzylinder duch eine Leitung hydraulisch miteinander verbunden.
Die Kolben der Druckzylinder sind zugleich Arretierungen. Dadurch, daß die Fußstandelemente an ihren Außenseiten Aufnahmezapfen, und an den Innenseiten Arretierungsvor­richtungen aufweisen, können sie außen in Bindungs­automaten, und innen an den Kolben der Druckzylinder arretiert werden.
Sowohl Automaten, wie auch Druckzylinder sind fest auf das Board montiert.
Dadurch, daß die Fußstandelemente auf gleitfördernden Unterlagen liegen, die auf das Board montiert sind, ist eine einwandfreie Torsionsauslösung gewährleistet.
Dadurch, daß die äußeren Aufnahmezapfen in ihren Abmessungen den Zapfen an Skischuhen entsprechen können, ist es möglich, herkömmliche Skibindungsautomaten als Auslöser zu verwenden.
Dadurch, daß die Fußstandelemente in Form von Platten aus sclagzähem Kunststoff gefertigt sind, können auf Ihnen bewährte Schuhaltesysteme (Schnallen/Bügel), aufmontiert werden.
Dies ermöglicht eine Verwendung des Auslösestandplatten­systems nach bewährtem Skibindungsprinzip, mit dem Unterschied, daß beide Fußstandelemente in Abhängigkeit voneinander nahezu gleichzeitig auslösen, dadurch daß nach Auslösung eines Elementes der Kolben des anderen Druckzylinders den Gegendruck verliert und somit freigibt.In order to ensure such a triggering also with regard to torsional stability, in one exemplary embodiment pressure cylinders are hydraulically connected to one another by a line.
The pistons of the pressure cylinders are also locks. Characterized in that the foot stand elements on their outer sides receiving pins and locking devices on the inner sides, they can be locked on the outside in binding machines and on the inside of the pistons of the pressure cylinders.
Both machines and pressure cylinders are firmly mounted on the board.
The fact that the footstand elements lie on slidable supports that are mounted on the board ensures that the torsion is triggered properly.
Because the dimensions of the outer receiving pins can correspond to the pins on ski boots, it is possible to use conventional automatic ski binding machines as triggers.
Due to the fact that the footstand elements are made of impact-resistant plastic, tried and tested shoe retention systems (buckles / brackets) can be mounted on them.
This enables the release base plate system to be used according to the proven ski binding principle, with the difference that both foot stand elements release almost simultaneously as a function of one another, in that after triggering one element the piston of the other pressure cylinder loses the counterpressure and thus releases it.

Die mit der Erfindung erzielten Vorteile liegen insbesondere darin, daß erhebliche Verletzungsgefahren des Snowboard-Fahrers dadurch vermieden werden, daß sich der ganze Körper im Sturzfalle vom Snowboard trennt, und nach der Auslösung beide Beine einzeln frei sind, was je nach Gelände, in dem der Sturz stattfindet, ein Vorteil sein kann. (Pflanzenbewuchs, steiles, vereistes Gelände).
Das System ist nahezu verschleißfrei und sicher in der Anwendung.
Im übrigen bedeutet es eine erhöhung des Komforts.The advantages achieved by the invention are, in particular, that considerable risk of injury to the snowboard driver is avoided by the fact that the entire body is separated from the snowboard in the event of a fall, and after the release both legs are individually free , depending on the terrain in which the Fall occurs, can be an advantage. (Vegetation, steep, icy terrain).
The system is almost wear-free and safe to use.
Otherwise it means an increase in comfort.

Die Verwendung von hydraulischen Druckzylindern hat gegenüber denkbaren mechanischen Lösungen den Vorteil, daß Verwindungen und Verbiegungen durch den Snowboard gebrauch sich nicht auf die Bindungsfunktion negativ auswirken.
Ausführungsbeispiele der Erfindung sind in der Zeichnung dargestellt und werdem im folgenden näher beschrieben:
