Description

Gegenstand der Erfindung ist eine neuartige Befestigungsweise des Wischerblattes. Bisher übliche Ausführungen verwenden für die Verbindung Niete oder Splinte, mit denen das Wischerblatt im Wischerarm selbst oder in einem an ihm befestigten Blechbügel leicht beweglich gehalten wird. Hierbei ergeben sich jedoch einige Nachteile. Beim Niet ist die Auswechslung eines Wischerblattes nach erfolgter Abnützung schwierig, zum mindesten für den Nichtfachmann und ohne Hilfswerkzeuge. Beim Splint ist die Auswechslung zwar leichter möglich, doch stören hier die vorstehenden, umgelegten Splintenden. Daher sind auch Ausführungen bekannt geworden, bei denen das Wischerblatt in einen Haken oder in eine öse am Wischerarm eingehängt wird. Diese Befestigungsart ist jedoch unsicher oder verhältnismäßig teuer.The invention relates to a novel method of attachment of the Wiper blade. Previously common designs use rivets or for the connection Cotter pins with which the wiper blade is attached to the wiper arm itself or to one Sheet metal bracket is kept easily movable. However, there are some disadvantages here. With rivets, it is difficult to replace a wiper blade after it has worn out, at least for the non-specialist and without auxiliary tools. With the sapwood it is Substitution is easier possible, but the above, put down interfere here Cotter pin ends. Therefore, designs are also known in which the wiper blade is hung in a hook or in an eyelet on the wiper arm. This type of attachment however, it is unsafe or relatively expensive.

Erfindungsgemäß verbindet die neue Befestigung die Vorteile der genannten bekannten Anordnungen; ihr Aufbau ist folgender: Nach Fig. i und 2 ist das Wischerblatt a an der Stelle, an der sich sonst der Splint befindet, durchbohrt und durch die Bohrung ist ein Ring b gezogen. Dieser Ring paßt federnd in die entsprechend ausgewölbten Schenkel des Wischerarmes d oder eines an ihm befestigten Blechbügels c. Das Wischerblatt wird ohne weitere Befestigung nur durch Klemmung gehalten und kann bei Bedarf mit dem Ring aus der Klemmfassung herausgezogen werden. Um das Geräusch zu dämpfen, das beim Umlegen des Wischerblattes in den Umkehrpunkten entsteht, ist z«-isclien Wischerblattrücken und Wischerarm bzw. Bügel eine Gummieinlage e vorgesehen. Diese besitzt zwei Schlitze, durch die, wie in Fig. 3 gezeigt, die zur Klemmanlage kommenden Teile des Ringes b hindurchragen und somit die Einlage gegen Verlieren sichern.According to the invention, the new attachment combines the advantages of the above known arrangements; their structure is as follows: According to FIGS. 1 and 2, the wiper blade is a pierced at the point where the split pin is otherwise and through the Bore is drawn a ring b. This ring fits resiliently into the correspondingly bulged Leg of the wiper arm d or a sheet metal bracket attached to it c. The wiper blade is held by clamping without any further fastening and can be used with be pulled out of the clamp socket with the ring. To muffle the sound that occurs at the reversal points when the wiper blade is turned over, is z «-isclien Wiper blade back and wiper arm or bracket a rubber insert e is provided. These has two slots through which, as shown in Fig. 3, the coming to the clamping system Parts of the ring b protrude and thus secure the insert against loss.

Diese Befestigungsart des Wischerblattes am Wischerarm ist einfach in der Herstellung, ergibt ein gutes Aussehen und vermeidet weitgehend Reibungsstellen, die zu einer Beschädigung der meist verchromten Teile führen könnten.This type of attachment of the wiper blade to the wiper arm is simple in the production, gives a good appearance and largely avoids friction points, which could damage most of the chrome-plated parts.
