Description
Lagerteil für einen Scheibenwischerarm Die Erfindung bezieht sich auf einen Lagerteil für einen Scheibenwischerarm zum Befestigen auf der Wischerwelle mit einem Gelenk zum Abklappen des Wischers von der Scheibe und mit einer U-förmigen Aussparung zur Aufnahme einer Druckfeder, die den Wischerarm gegen die Scheibe drückt.Bearing part for a windshield wiper arm The invention relates on a bearing part for a windshield wiper arm for fastening on the wiper shaft with a hinge for folding down the wiper from the window and with a U-shaped Recess to accommodate a compression spring that presses the wiper arm against the window.
Die Druckfeder kann in besonders einfacher und billiger Weise zuverlässig in dem Lagerteil befestigt werden, wenn gemäß der Erfindung der Grund der U-förmigen Aussparung dem Durchmesser der einzulegenden Feder angepaßt ist und beiderseits in parallele Wandungen mit zungenförmigen Enden übergeht, die nach dem Einsetzen der Feder gegeneinandergebogen werden und die Feder übergreifen.The compression spring can be reliable in a particularly simple and inexpensive manner be fixed in the bearing part if, according to the invention, the bottom of the U-shaped Recess is adapted to the diameter of the spring to be inserted and on both sides merges into parallel walls with tongue-shaped ends, which after insertion the spring are bent against each other and overlap the spring.
Diese Art der Lagerung und Sicherung der Feder hat sich als besonders vorteilhaft erwiesen, weil --die Herstellung der U-förmigen Aussparung keinerlei :Schwierigkeiten bei der Herstellung des Lagerteils aus Spritzguß bereitet, da sie keinen Unterschnitt erfordert. Außerdem kann die Feder bei der Montage sehr leicht eingesetzt werden. Das anschließende Verstemmen der Zunge bereitet ebenfalls keine Umstände und gewährleistet eine gute Sicherung der Feder, da das Verstemmen den Toleranzen der Federabmessungen bequem angepaßt werden kann, so daß die Feder nach Verstemmung immer sicher sitzt.This type of storage and securing of the spring has proven to be special proved advantageous because - the production of the U-shaped recess no : Difficulties in the production of the bearing part from injection molding, because they does not require an undercut. In addition, the spring can be very light during assembly can be used. The subsequent caulking of the tongue does not prepare either Circumstances and ensures a good backup of the spring, since the caulking the Tolerances of the spring dimensions can be easily adjusted so that the spring after The caulking always sits securely.
Die Erfindung ist an Hand der Zeichnung näher erläutert, in der ein Scheibenwischerarm in Fig. 1 im Längsschnitt, in Fig. 2 im Querschnitt A-B vor dem Verstemmen der Zungen und in Fig.3 nach dem Verstemmen der Zungen dargestellt ist.The invention is explained in more detail with reference to the drawing, in which a Wiper arm in Fig. 1 in longitudinal section, in Fig. 2 in cross section A-B before Caulking the tongues and is shown in Figure 3 after the tongues have been caulked.
Mit 1 ist ein Lagerteil aus Spritzguß bezeichnet, das über ein Befestigungsteil 2, das an dem Lagerteil l angelenkt ist, mit der nicht dargestellten Wischerwelle verschraubt werden kann. Am freien Ende des Lagerteils ist ein Wischarm 3 befestigt, der an seinem freien Ende 4 ein nicht dargestelltes Wischblatt trägt. Am Lagerteil ist eine Schraubendruckfeder 5 vorgesehen, die das Bestreben hat, das Wischblatt in Arbeitsstellung des Wischers gegen die Scheibe zu pressen. Diese Schraubenfeder stützt sich einerseits an dem Befestigungsteil und andererseits an einer Fläche 6 des Lagerteils ab. Diese Fläche weist, wie aus Fig. 2 ersichtlich, eine U-förmige Aussparung 7 auf, deren Grunddurchmesser etwas größer als der der Schraubenfeder ist. Die zunächst noch parallelen Wandungen der Aussparung enden in Zungen 8 und 9. In diese Aussparung wird die Schraubenfeder von unten eingeschoben. Dann werden die beiden überstehenden Zungen 8 und 9 verstemmt, so daß sie in die in Fig.3 dargestellte Lage kommen und die Schraubenfeder überreifen.1 with a bearing part made of injection molding is referred to, which has a fastening part 2, which is hinged to the bearing part l, with the wiper shaft, not shown can be screwed. A wiper arm 3 is attached to the free end of the bearing part, which carries a wiper blade (not shown) at its free end 4. On the bearing part a helical compression spring 5 is provided, which tends to move the wiper blade to press against the window in the working position of the wiper. This coil spring is supported on the one hand on the fastening part and on the other hand on a surface 6 of the bearing part. As can be seen from FIG. 2, this surface is U-shaped Recess 7, the base diameter of which is slightly larger than that of the helical spring is. The initially still parallel walls of the recess end in tongues 8 and 9. The helical spring is pushed into this recess from below. Then will the two protruding tongues 8 and 9 caulked so that they are in the one shown in FIG Situation and overripe the coil spring.
