Description

Scheibenwischer mit auf und nieder gehenden Wischblättern für Kraftfahrzeuge Gegenstand der Erfindung ist ein Scheibenwischer für Kraftfahrzeuge mit auf und nieder gehenden Wischblättern. Derartige Scheibenwischer sind bekannt, aber nur für Fahrzeuge alter Bauart mit lotrecht stehender ungeteilter Windschutzscheibe. Man konnte bei diesen Fahrzeugen den Antrieb des Wischers ohne Schwierigkeit hinter dem Spritzbrett unterhalb der unteren Leisten des Windschutzscheibenrahmens anordnen. Diese Möglichkeit *ist nicht gegeben bei neuzeitlichen Kraftfahrzeugen, die mit Rücksicht auf die Verminderung des Luftwiderstandes mehr oder weniger stromlinienförmig gehalten und niedrig gebaut werden. Die Windschutzscheiben stehen in der Regel schräg und sind entweder gekrümmt oder keilförmig gestaltet. Der Scheibenrahmen selbst wird mit einer Mittelrippe ausgestattet.Windshield wipers with up and down wiper blades for motor vehicles The invention relates to a windshield wiper for motor vehicles with on and falling wiper blades. Such windshield wipers are known, but only For old-style vehicles with a vertical, undivided windshield. With these vehicles, you could drive the wiper behind without difficulty the splashboard below the lower ledges of the windshield frame. This option * is not available for modern motor vehicles that are equipped with Consideration for the reduction of the air resistance more or less streamlined be held and built low. The windshields are usually at an angle and are either curved or wedge-shaped. The pane frame itself is equipped with a central rib.

Erfindungsgemäß wird nun die Mittelrippe dazu verwendet, die Geradführung der Wischblätter aufzunehmen. Der Vorteil dieser Anordnung besteht vor allem darin, daß auf diese Weise ein Antrieb ' für die Scheibenwischer geschaffen werden kann, der an fast allen Scheiben verwendbar ist. Die Scheiben sind bekanntlich in ihrer Höhe wenig voneinander verschieden, haben aber je nach den Kraftwagentypen verschiedene Breitenabmessungen. Man kann daher einen und denselben Wischerantrieb für verschiedene Wagentypen verwenden, man braucht nur die passenden Wischblätter an den Wischerarmen anzusetzen. auf der Zeichnung ist ein Ausführungsbeispiel eines Scheibenwischers mit auf und nieder bewegten Wischblättern gemäß der Erfindung dargestellt, bei dem als Antriel?#-r'' Vorrichtung ein Luftmotor verwendet ist.According to the invention, the central rib is now used to guide the straight line to record the wiper blades. The main advantage of this arrangement is that that in this way a drive can be created for the windshield wipers, which can be used on almost all panes. The discs are known to be in theirs Height slightly different from each other, but have different depending on the type of motor vehicle Width dimensions. You can therefore use one and the same wiper drive for different ones Use car types, you just need the right wiper blades on the wiper arms to apply. on the drawing is an embodiment of one Wiper shown with up and down moving wiper blades according to the invention, in which an air motor is used as the drive device.

Abb. i ist eine Ansicht des Scheibe i1-wischers in schematischer Darstellung, Abb. 2 eine Aufsicht auf den Scheibenwischer mit gekrümmten Windschutzscheiben, Abb.3 eine abgeänderte Ausführungsfarm des Wischerantriebes nach ASS. 2.Fig. I is a schematic view of the windshield i1 wiper, Fig. 2 is a plan view of the windshield wiper with curved windshields, Fig.3 a modified version of the wiper drive according to ASS. 2.

i bezeichnet die zweiteilige gerade oder gekrümmte Windschutzscheibe, die in den Rahmen 2 mit Mittelrippe 3 eingebracht ist: An der Mittelrippe sitzt die Antriebsvorrichtung für die Wischerarme .1, an der die Wischglätter 5 auswechselbar befestigt sind.i denotes the two-part straight or curved windshield, which is introduced into the frame 2 with the central rib 3: sits on the central rib the drive device for the wiper arms .1, on which the wiper blades 5 can be exchanged are attached.

Die Antriebsvorrichtung besteht im Ausführungsbeispiel aus einem Luftzylinder 6 mit Kolben 7 (Fig. 3 ), dessen Kolbenstange 8 um die Höhe des Kolbenhubes rückwärts gekröpft ist, um in Höhe des Kolbens die Wischerarme.l aufzunehmen. Die Kröpfung des Kolbens kann gemäß> Abb.2 in der senkrechten Längsmittelebene des Fahrzeuges in einem Ast oder gemäß ASS. 3 quer zurLängsmittelebene in zwei fisten erfolgen.In the exemplary embodiment, the drive device consists of an air cylinder 6 with a piston 7 (FIG. 3 ) , the piston rod 8 of which is cranked backwards by the height of the piston stroke in order to accommodate the wiper arms at the height of the piston. The cranking of the piston can be in a branch according to> Fig. 2 in the vertical longitudinal center plane of the vehicle or according to ASS. 3 transversely to the median longitudinal plane in two fists.

Bei dieser Anordnung heben sich die Sei-t' auf die Führung, die durch den notwendigen Anpressungsdruck der Wischerblättc4 auf die Scheibe hervorgerufen «-erden, im wesentlichen auf. Xbgesehen davon ist aber auch durch Wahl geeigneter Baustoffe, die eine Durchbiegung der Kolbenstange zulassen, wie z. B. Simmerit, die Gewähr dafür gegeben, daß ein Verklemmen der Führung und ein Undichtwerden der Stopfbuchsen infolge Verbiegung der Kolbenstange nicht eintritt.In this arrangement, the sides lift t 'to the guide caused by the necessary Anpressungsdruck the Wischerblättc4 on the disc "-erden substantially on. Apart from this, however, it is also possible to choose suitable building materials that allow the piston rod to bend, such as B. Simmerit, the guarantee that jamming of the guide and leakage of the stuffing boxes due to bending of the piston rod does not occur.
