Description
'Gegenstand vorliegender Erfindung betrifft eine Schalteranordnung an dem Werkzeughalter von biegsamen Wellen.The present invention relates to a switch arrangement on the tool holder of flexible shafts.
Bei Verwendung von biegsamen Wellen, die direkt an die Achse des Motors angeschlossen sind, ist es zum Nachteil, daß ein Schalter nur ami Motor vorgesehen ist. Da die biegsamen Wellen meistens. eine Länge von mehreren Metern haben, so hat dies zur Folge, daß bei Vornahme von. Arbeiten in weniger günstiger Stellung der Arbeiter seinen Platz verlassen muß, um den Motor ein- und ausschalten zu können.When using flexible shafts that are directly connected to the axis of the motor it is disadvantageous that a switch is only provided on the motor. Since the flexible shafts mostly. a length of several meters, this has the consequence that when making. Work in less favorable position the worker has to leave his place to start the engine to be able to switch it on and off.
Um nun diese Nachteile zu beseitigen, wird gemäß der vorliegenden Erfindung eine Anordnung am Werkzeughalter der biegsamen Welle angebracht, die den "Schalter des Motors betätigt.In order to overcome these disadvantages, according to the present invention, a Arrangement attached to the tool holder of the flexible shaft, which is the "switch of the Motor operated.
Dies wird dadurch erreicht, daß auf der Achse des Schalters am Motor ein unter Federwirkung stehender Hebel befestigt ist, der unter Vermittlung eines entlang der bieg-This is achieved by placing an under on the axis of the switch on the motor Spring action standing lever is attached, which is mediated by a along the flexible
samen Welle gleitenden Bowdenzüge© durch einen am Werkzeughalter oder Schlauch der biegsamen Welle angebrachten Hebel oder • eine ähnliche Anprdnung betätigt wird. Durch diese Anordnung wird es ermöglicht, . daß der Motor von jeder Arbeitsstellung aus ein- und ausgeschaltet werden kann, ohne daß der Arbeiter die Arbeitsstelle verlassen muß. Auf der Zeichnung ist ein Erfindungsbei ■ ίο spiel schematisch dargestellt und näher erläutert. Bowden cables © sliding on the same shaft through a tool holder or hose on the lever attached to a flexible shaft or • a similar device is actuated. This arrangement makes it possible. that the engine works from every working position can be switched on and off without the worker having to leave the workplace. In the drawing, an example of the invention is shown schematically and explained in more detail.
An die Achse des Motors α ist die biegsame Welle b direkt angeschlossen. Auf der Schalterachse c ist ein Hebel d befestigt, der durch eine Zugfeder e den Schalter für den Motor α in Ausschaltstellung hält. Ein Bowdenzug / j ist an dem Hebel d befestigt, der entlang der I biegsamen Welle läuft und am Werkzeughalter oder Schlauch, wie es auf der Zeichnung beispielsweise dargestellt ist, durch einen Hebel g betätigt wird. Soll nun der Motor eingeschaltet werden, so wird dies durch Zurückwerfen des Hebels g in der punktierten Stellung erreicht.The flexible shaft b is directly connected to the axis of the motor α. On the switch axis c , a lever d is attached, which holds the switch for the motor α in the off position by a tension spring e. A Bowden cable / j is attached to the lever d , which runs along the flexible shaft and is operated by a lever g on the tool holder or hose, as is shown in the drawing, for example. If the motor is now to be switched on, this is achieved by throwing the lever g back into the dotted position.
