Description

Scheibenwischer für Kraftfahrzeuge Die Erfindung betrifft Scheibenwischer, die mit Seilen über Schnurlaufrollen angetrieben werden.Windshield wipers for motor vehicles The invention relates to windshield wipers, which are driven with ropes via pulleys.

Derartige Scheibenwischer sind teilweise mit Friktionskupplungen und Anschlägen zur Begrenzung der Amplitude ihrer Wischbewegungen ausgestattet. Solche Konstruktionen sind jedoch aufwendig und kompliziert.Such windshield wipers are partially with friction clutches and Stops equipped to limit the amplitude of their wiping movements. Such However, constructions are expensive and complicated.

Nach der Erfindung wird eine wesentliche Vereinfachung und Verbilligung dadurch erzielt, daß Anschläge zum Begrenzen der Amplitude der Wischbewegungen innerhalb der Schnurlaufrolle angeordnet werden. Hierbei können, um den Anschlag zu dämpfen, Puffer aus Weichmaterial an den Anschlägen vorgesehen werden.According to the invention, there is a substantial simplification and cheaper achieved in that stops to limit the amplitude of the wiping movements within the line roller. Here, in order to dampen the attack, Soft material buffers are provided on the stops.

Die Erfindung ist an Hand der Zeichnung beschrieben. Es zeigt Fig. 1 einen Längsschnitt durch die Vorrichtung, Fig. 2 die Schnurlaufrolle in Aufsicht und Fig. 3 die Anordnung auf der Grundplatte.The invention is described with reference to the drawing. It shows Fig. 1 shows a longitudinal section through the device, FIG. 2 shows the line roller in plan view and FIG. 3 shows the arrangement on the base plate.

In der Zeichnung ist mit 1 die drehbar in einer Grundplatte 2 gelagerte Welle bezeichnet, an deren freiem Ende der Arm des Scheibenwischers, welcher der Übersicht halber nicht dargestellt ist, aufgekeilt werden kann. Am anderen Ende der Wischerwelle 1 ist eine Schnurlaufrolle 3 aufgekeilt, um die ein Seil 4 zweimal geschlungen ist, das zum Übertragen der Schwenkbewegungen vom Antriebsmotor auf die Wischerwelle 1 vorgesehen ist. Das Seil ist an einer Stelle der Schnurlaufrolle 3, an der es sich bei Betrieb nicht von der Schnurlaufrolle abhebt, mit dieser beispielsweise durch Verkeilung fest verbunden. Die Schnurlaufrolle weist einen halbkreisförmigen Einschnitt 5 auf, der durch elastische Puffer 7, bestehend aus Weichmaterial, begrenzt ist.In the drawing, 1 is the rotatably mounted in a base plate 2 Shaft referred to, at the free end of the arm of the wiper, which the Is not shown for the sake of clarity, can be wedged. On the other end the wiper shaft 1 is keyed to a cord pulley 3, around which a rope 4 twice is looped, which is used to transfer the pivoting movements from the drive motor the wiper shaft 1 is provided. The rope is at one point on the line pulley 3, on which it does not stand out from the line roller during operation, with this for example firmly connected by wedging. The line roller has a semicircular shape Incision 5, which is limited by elastic buffers 7 made of soft material is.

In diesen Einschnitt greift eine Nase 8, die, wie aus Fig. 3 ersichtlich, verdrehungssicher an der Grundplatte befestigt ist. Der Antrieb ist so ausgebildet, daß das Seil 4 hin- und hergehende Bewegungen ausführt, so daß die Schnurlaufrolle 3 und mit ihr die Welle 1 des Scheibenwischers oszillierende Bewegungen ausführen. Bei diesen Bewegungen gleitet die Nase 8 in dem Einschnitt 5. An den Enden der Drehausschläge stoßen die Puffer 6 bzw. 7 gegen die Nase 8, wodurch die Amplitude und Winkellage der oszillierenden Bewegung der Teile 3 und 1 bestimmt werden. Die Bewegung des Seiles 4 ist mit einem geringen Überschuß bemessen. Dieser Überschuß wird beim Anschlagen der Puffer 6 oder 7 an die Nase 8 durch Elastizität des Seiles 4 bzw. durch eine in dem Seil 4 zu diesem Zweck angeordnete Feder aufgefangen.A nose 8 engages in this incision which, as can be seen from FIG. 3, is secured against rotation on the base plate. The drive is designed in such a way that that the rope 4 performs reciprocating movements, so that the cord pulley 3 and with it the shaft 1 of the windshield wiper perform oscillating movements. During these movements, the nose 8 slides in the incision 5. At the ends of the rotary strokes bump the buffers 6 and 7 against the nose 8, whereby the amplitude and angular position the oscillating movement of parts 3 and 1 can be determined. The movement of the Rope 4 is dimensioned with a small excess. This excess is used when striking the buffer 6 or 7 to the nose 8 by elasticity of the rope 4 or by a in the rope 4 arranged for this purpose spring is caught.

In Abänderung dieses Ausführungsbeispiels kann auch auf die Fixierung des Seiles an der Schnurlaufrolle 3 und auf die Elastizität des Seiles verzichtet werden. Der Überschuß der Seilbewegung wird dann durch ein Rutschen des Seiles auf der Schnurlaufrolle 3 aufgefangen. Um dieses Rutschen zu begünstigen, empfiehlt es sich, in einem solchen Fall auf die doppelte Umschlingung der Schnurlaufrolle 3 durch das Seil 4 zu verzichten und das Seil 4 nur einmal um die Rolle 3 zu legen.In a modification of this exemplary embodiment, the fixation can also be used of the rope on the cord roller 3 and waived the elasticity of the rope will. The excess of the rope movement is then caused by the rope slipping up the line roller 3 caught. To encourage this slipping, recommends In such a case, the double wrapping of the cord roller 3 by the rope 4 and to put the rope 4 only once around the roller 3.
