Abstract

The wide area windscreen wiper has the wiper arm mounted on a linear motor which moves along a guide under the windscreen. The motor strikes microswitches at each end of its travel to operate a reversing control. The system wipes into the corners of the windscreen. It requires no complex wiper drives and few moving parts. The system can support one or more wiper blades so that large, wide windscreens can be wiped.

Description

ScheibenwischerantriebO Wiper driveO

Die Erfindung betrifft einen Scheibenwischersntrieb für Land-, Liift- und Wasserfahrzeuge0 Bekannt sind Lösungen bei denen die Wischerblätter mittels Zahnräder oder Gestänge von einem Elektromotor mit rotierenden fflriebwerksteilen schwenkend bewegt werden, Demgegenüber werden die Wischerblätter bei der vorliegenden Erfindung ohne Zwischenschaltung von Getrieben und Gestängen mit Gelenken in einfacher Weise von einem Binearmotor hin und her bewegt, Sie können dabei je nach Ausführung des Motores eine gerade oder leicht gewölbte Bahn beschreiben0 Die Zeichnung zeigt ein Ausführungsbeispiel schematisch, Über der Fahrzeugscheibe 1 rutschen die beiden Wischerblätter 2, 3, die mit einfachen Gelenken 4, 5 oder auch starr an der Reaktionsschiene 6 befestigt sind0 in Richtung M bzw0 N hin bzw0 zurück. Diese Schiene ist Teil des Linearmotores und wird vom Stator 7 in Längsrichtung bewegt, Das Umsteuern der Bewegungsrichtung geschieht dabei durch Umpolschalter8, 9, die in der Art von Endschaltern ausgeführt sein können0 Die Wischgeschwindigkeit der Wischerblätter kann mit einem elektronischen Regelgerät 10 reguliert werden,The invention relates to a windshield wiper drive for land, Liift- and water vehicles0 are known solutions in which the wiper blades by means of Gears or linkages from an electric motor with rotating engine parts be moved pivoting, In contrast, the wiper blades in the present Invention without the interposition of gears and linkages with joints in a simple way Way moved back and forth by a binary motor, you can do this depending on the design Describe a straight or slightly curved path of the motor 0 The drawing shows an exemplary embodiment schematically, the two slide over the vehicle window 1 Wiper blades 2, 3, with simple joints 4, 5 or rigidly on the reaction rail 6 are attached 0 in the direction of M or 0 N there or back. This rail is part of the Linear motor and is moved by the stator 7 in the longitudinal direction, reversing the direction of movement happens through polarity reversal switches 8, 9, which are designed in the manner of limit switches 0 The wiping speed of the wiper blades can be controlled by an electronic Control device 10 are regulated,
