Description

Lagerteil zum Anlenken eines WischblattsBearing part for articulating a wiper blade
Stand der TechnikState of the art
Die Erfindung geht aus von einem Lagerteil zum Anlenken eines Wischblatts nach dem Oberbegriff des Anspruchs 1.The invention relates to a bearing part for articulating a wiper blade according to the preamble of claim 1.
Bekannte Scheibenwischer besitzen einen Wischarm, der aus einem Befestigungsteil und einem daran angelenkten Gelenkteil mit einer Wischstange aufgebaut ist. Ferner haben sie ein Wischblatt, das aus einem Tragbügelsystem mit einem übergeordneten Mittelbügel und gelenkig verbundenen, untergeordneten Zwischenbügeln sowie Krallenbügeln und einer Wischleiste aufgebaut ist. Das Wischblatt ist am Wischarm angelenkt, indem ein hakenförmiges Ende der Wischstange ein Lagerteil hält, das zwischen zwei Seitenwangen des Mittelbügels ange¬ ordnet .ist und mit einer über einen Umfangsbereich offenen Nabe einen Gelenkbolzen des Mittelbügels umfaßt. Das so gebildete Gelenk führt das Wischblεtt während der Schwenkbewegung über -die Scheibe, wobei das Gelenk und das Tragbüσelsy- stem es ermöglichen, da.ß sich die Wischleiste einer Wölbung der Scheibe anoassen kann. Aus der DE 86 09 984 Ul ist ein Lagerteil bekannt, das mit seiner offenen Nabe über einen Lagerbolzen eines Wischblatts gesteckt und durch einen Rastzahn gehalten wird. Danach wird ein hakenförmiges Ende einer Wischstange von der geschlosse- nen Seite der Nabe her über das Lagerteil gezogen, bis ein Rastloch in dem kurzen Schenkel des hakenförmigen Endes mit einer Rastnase am Lagerteil verrastet. Dabei liegt der Lagerbolzen zwischen dem kurzen und langen Schenkel des hakenförmigen Teils im Bereich des Verbindungsbogens der beiden Schenkel an, während die Öffnung der Nabe im wesentlichen parallel zu den Schenkeln gerichtet ist. Zur Montage muß das Wischblatt in verschiedene Bewegungsrichtungen zum hakenförmigen Ende der Wischstange geführt werden, wobei auch eine untaugliche Lage des Wischblatts erreicht werden kann, so daß es demontiert und erneut richtig montiert werden muß.Known windshield wipers have a wiper arm which is constructed from a fastening part and an articulated part articulated thereon with a wiper rod. They also have a wiper blade, which is made up of a support bracket system with a superordinate center bracket and articulated, subordinate intermediate brackets as well as claw brackets and a wiper strip. The wiper blade is articulated on the wiper arm by a hooked end of the wiper rod holding a bearing part, which is between two side cheeks of the center bracket ¬ assigns .is and with an open over a peripheral region hub comprises a hinge pin of the central strap. The joint formed in this way guides the wiper blade during the swiveling movement over the window, the joint and the support bracket system making it possible for the wiper strip to be able to bend the window. From DE 86 09 984 Ul a bearing part is known which is inserted with its open hub over a bearing pin of a wiper blade and is held by a locking tooth. A hook-shaped end of a wiper rod is then pulled over the bearing part from the closed side of the hub until a latching hole in the short leg of the hook-shaped end is latched with a latching lug on the bearing part. The bearing pin lies between the short and long legs of the hook-shaped part in the area of the connecting bend of the two legs, while the opening of the hub is directed essentially parallel to the legs. For assembly, the wiper blade must be guided in different directions of movement to the hook-shaped end of the wiper rod, and an unsuitable position of the wiper blade can also be achieved, so that it has to be dismantled and correctly installed again.
Vorteile der ErfindungAdvantages of the invention
Nach der Erfindung weist die Öffnung der Nabe zum kurzen Schenkel des hakenförmigen Endes, wird von diesem jedoch nicht überdeckt. Dadurch kann das Lagerteil zunächst in das hakenförmige Ende eingesetzt werden und dann kann das Wischblatt mit seinem Lagerbolzen quer zur Wischstange in die Öffnung der Nabe geschoben werden. Damit der Lagerbolzen si- eher in der Nabe gehalten wird, sind zu beiden Seiten derAccording to the invention, the opening of the hub faces the short leg of the hook-shaped end, but is not covered by it. As a result, the bearing part can first be inserted into the hook-shaped end and then the wiper blade with its bearing bolt can be pushed into the opening of the hub transversely to the wiper rod. So that the bearing pin is held more securely in the hub, are on both sides
Öffnung Federzungen angeordnet. Führungsflächen an den Federzungen erleichtern die Montage des Wischblatts. Eine Fehlmontage ist praktisch ausgeschlossen.Opening spring tongues arranged. Guide surfaces on the spring tongues facilitate the assembly of the wiper blade. Incorrect assembly is practically impossible.
Seitlich der Schenkel des hakenförmigen Endes der Wischstanσe besitzt das Lagerteil Führungsflächen. Die entsprechenden Wandteile dienen außerdem nach außen zur Führung des Lager- teiles in einem Mittelbügel des Wischblatts, wobei sich zweckmäßigerweise die Führungsflächen in Längsrichtung zu beiden Seiten der Nabe erstrecken und einer Öffnung zwischen den Seitenwangen des Mittelbügels des Wischblatts angepaßt sind. Dadurch ergibt sich eine lange, stabile und schwin- gungsfreie Führung des Wischblatts gegenüber der Wischstange.The bearing part has guide surfaces on the side of the leg of the hook-shaped end of the wiper stems. The corresponding wall parts also serve to guide the bearing part outwards in a central bracket of the wiper blade, whereby Expediently, the guide surfaces extend in the longitudinal direction on both sides of the hub and an opening between the side cheeks of the center bracket of the wiper blade is adapted. This results in a long, stable and vibration-free guidance of the wiper blade relative to the wiper rod.
Das Lagerteil ist in üblicher Weise mittels einer Rastnase und einem Rastloch im hakenförmigen Ende der Wischstange gesichert, wobei in vorteilhafter Weise eine in Längsrichtung wirkende Federzunge die Rastverbindung unter Vorspannung hält.The bearing part is secured in the usual manner by means of a latching lug and a latching hole in the hook-shaped end of the wiper rod, an elastic tongue acting in the longitudinal direction advantageously holding the latching connection under tension.

Das Lagerteil 30 erstreckt sich in Längsrichtung beiderseits einer Nabe 36, die zum kurzen Schenkel 66 hin eine Öffnung 42 aufweist. Allerdings läßt der kurze Schenkel 66 die Öffnung 42 frei, so daß der Lagerbolzen 28 nach der Montage des La- gerteils 30 im hakenförmigen Ende 20 der Wischstange 18 in die Nabe 36 eingeführt werden kann. Um den Lagerbolzen 28 in der Nabe 36 zu halten, sind zwei Federzungen 46 und 44 vorgesehen, die Schrägflächen 48 und 50 aufweisen, so daß sich die Öffnung 42 nach außen erweitert, um die Montage zu erleich- tern.The bearing part 30 extends in the longitudinal direction on both sides of a hub 36 which has an opening 42 towards the short leg 66. However, the short leg 66 leaves the opening 42 free, so that the bearing pin 28 can be inserted into the hub 36 after the mounting of the bearing part 30 in the hook-shaped end 20 of the wiper rod 18. In order to hold the bearing pin 28 in the hub 36, two spring tongues 46 and 44 are provided, which have inclined surfaces 48 and 50, so that the opening 42 widens outwards in order to facilitate assembly.
Das Wischblatt 10 wird am hakenförmigen Ende 20 der Wischstange 18 montiert, indem sein Lagerbolzen 28 quer zur Wischstange 18 in die Nabe 36 eingeführt wird. Dabei nutzt das La- gerteil 30 die gesamte Öffnung 72 beiderseits des Lagerbolzens 28 im Mittelbügel 22 des Wischblatts 10. Somit ist eine lange, schwingungsfreie Führung zwischen dem Wischblatt 10 und der Wischstange 18 gewährleistet. The wiper blade 10 is mounted on the hook-shaped end 20 of the wiper rod 18 by inserting its bearing pin 28 into the hub 36 transversely to the wiper rod 18. The bearing part 30 uses the entire opening 72 on both sides of the bearing pin 28 in the central bracket 22 of the wiper blade 10. This ensures long, vibration-free guidance between the wiper blade 10 and the wiper rod 18.
