Description

Die Erfindung betrifft einen Wischgummi aus einem Wisch­ gummikopf, einem Umlegesteg und einer Lippe.The invention relates to a squeegee from a wipe rubber head, a transfer bridge and a lip.

Wischgummis der genannten Art werden insbesondere als Scheibenwischer für Kraftfahrzeuge eingesetzt. Solche Wischgummis werden beispielsweise in der DE-C3 34 40 677 oder in der DE-C2 35 38 085 beschrieben.Wiper rubbers of the type mentioned are in particular as Windshield wipers used for motor vehicles. Such Wiper rubbers are described, for example, in DE-C3 34 40 677 or described in DE-C2 35 38 085.

Bei Wischgummis, wie sie im Stand der Technik bekannt sind, sind Federleisten notwendig, die in Aussparungen des Wischgummikopfs sitzen.With squeegees, as they are known in the prior art are female connectors that are necessary in recesses of the squeegee head.

Ein solches Wischerblatt wird in der DE 196 15 421 beschrieben. Dieses Wischerblatt weist einen Wischerkopf zur Befestigung im Wischerbügel, einen Kippsteg und eine Wischerlippe auf, wobei der Wischerkopf und der Kippsteg aus Polychloropren oder einer Polymerenmischung aus einem Anteil von mindestens 60 Gew.-% Polychloropren und mindestens einem anderen Elastomer bestehen und die Wischerlippe zumindest in den Teilen, die mit der Glasscheibe in Berührung kommen, aus Naturgummi und bzw. oder einem synthetischen Elastomer auf Basis eines Diens mit Kohlenwasserstoffstruktur besteht.Such a wiper blade is described in DE 196 15 421 described. This wiper blade has a wiper head for fastening in the wiper bracket, a tilting bar and one Wiper lip on, with the wiper head and the tilting bar made of polychloroprene or a polymer blend of one Proportion of at least 60 wt .-% polychloroprene and at least one other elastomer and the Wiper lip at least in the parts with the Glass pane come into contact, made of natural rubber and / or or a synthetic elastomer based on a diene with hydrocarbon structure.

Die Aufgabe der vorliegenden Erfindung besteht daher darin, einen Wischgummi ohne Federleiste bereitzustellen und der von seiner Fertigung und Montage her einfach ist. The object of the present invention is therefore in providing a squeegee without a spring bar and which is simple in terms of its manufacture and assembly.  

Erfindungsgemäß wird die Aufgabe durch einen Wischgummi aus einem Wischgummikopf, einem Umlegesteg und einer Lippe gelöst, der dadurch gekennzeichnet, daß der Wisch­ gummikopf einen harten Kautschuk mit einer Shore-D-Härte von 30 bis 50, der Umlegesteg und die Lippe jedoch einen weichen Kautschuk mit einer Shore-A-Härte von 55 bis 75 umfassen.According to the invention, the task is performed by a squeegee from a squeegee head, a transfer bridge and one Lip loosened, characterized in that the wiping rubber head a hard rubber with a Shore D hardness from 30 to 50, but the transfer bridge and the lip one soft rubber with a Shore A hardness of 55 to 75 include.

Hierbei können verschiedenartige Polymertypen eingesetzt werden, wobei Kautschuke vom Dientyp und Thermoplaste bevorzugt sind.Different types of polymers can be used here be rubber of the service type and thermoplastics are preferred.

In einer besonders bevorzugten Ausführungsform ist der erfindungsgemäße Wischgummi einteilig. Bei dem ein­ teiligen Wischgummi liegt im Grenzbereich zwischen dem harten Kautschuk des Wischgummikopfs und dem weichen Kautschuk der Lippe ein Übergangsbereich hinsichtlich der Kautschukhärte vor.In a particularly preferred embodiment, the Wiper rubber according to the invention in one piece. With the one partial squeegee lies in the border area between the hard rubber of the squeegee head and the soft Rubber of the lip a transition area in terms of Rubber hardness.

Zur Herstellung des Wischgummis eignet sich besonders der Einsatz eines Extruders, durch den in besonders vorteil­ hafter Weise der einteilige Wischgummi mit zwei unter­ schiedlichen Kautschukhärten herstellbar ist.The is particularly suitable for producing the squeegee Use of an extruder, which is particularly advantageous the one-piece squeegee with two under different rubber hardness can be produced.

In vorteilhafter Weise benötigt der Wischgummikopf keine Aussparungen für die bisher notwendigen Federleisten, wo­ durch dieser in der Fertigung einfacher wird. Desweiteren besteht ein wesentlicher Vorteil vorliegender Erfindung darin, daß zur Herstellung des Wischgummis weniger Teile benötigt werden. The squeegee head advantageously does not require any Cutouts for the previously required female connectors, where making it easier to manufacture. Furthermore there is a significant advantage of the present invention in that fewer parts for the production of the squeegee are needed.  

In einer weiteren Ausführungsform ist der Wischgummi zweiteilig. Er besteht aus einem Wischgummikopf als ersten Teil und einem aus Lippe und Umlegesteg bestehen­ den zweiten Teil. Dieser ist mit dem Wischgummikopf ver­ rastbar und wird nachträglich in den Kopf hineingescho­ ben, wodurch sich eine besonders einfache Montage ergibt.In a further embodiment, the squeegee is in two parts. It consists of a squeegee head first part and one consist of lip and transfer bridge the second part. This is ver with the squeegee head restable and is subsequently shot into the head ben, which results in a particularly simple assembly.

Vorzugsweise besteht hierbei der Wischgummikopf aus einem Thermoplast. Hierbei sind Thermoplaste mit einer geeigneten Gleitfähigkeit bevorzugt.The wiper rubber head preferably consists of a Thermoplastic. Here are thermoplastics with a suitable lubricity preferred.

Zur Senkung des Reibungskoeffizienten kann der Wischgummi eine entsprechende Oberflächenbeschichtung erhalten, beispielsweise durch eine Halogenisierung. Ferner können Gleitpulver zugesetzt werden, wobei Molybdän oder Graphit enthaltende Gleitpulver bevorzugt sind.The squeegee can be used to reduce the coefficient of friction receive an appropriate surface coating, for example by halogenation. Can also Lubricant can be added, using molybdenum or graphite containing sliding powder are preferred.

Die Erfindung soll anhand beiliegender Zeichnung näher erläutert werden.The invention will be described in more detail with reference to the attached drawing are explained.

Fig. 1 stellt einen Schnitt in Längsrichtung durch einen einteiligen Wischgummi dar. Dieser besteht aus dem Wisch­ gummikopf 1 aus hartem Kautschuk und der Lippe 2 und dem Umlegesteg 3, jeweils aus weichem Kautschuk. Zwischen der Lippe 2 und dem Wischgummikopf 1 befindet sich ein Übergangsbereich 4 hinsichtlich der Kautschukhärte, der durch die Schraffur dargestellt ist. Fig. 1 shows a section in the longitudinal direction through a one-piece squeegee. This consists of the wiping rubber head 1 made of hard rubber and the lip 2 and the folding bridge 3 , each made of soft rubber. Between the lip 2 and the squeegee head 1 there is a transition region 4 with regard to the rubber hardness, which is represented by the hatching.

Fig. 2 stellt einen Schnitt in Längsrichtung durch einen zweiteiligen Wischgummi dar. Hierbei erfolgt die Verrastung zwischen dem Wischgummikopf 1 aus hartem Kautschuk und der Lippe 2 und dem Umlegesteg 3, jeweils aus weichem Kautschuk, durch einen Wulst 5, der mit dem Kopf 1 verrastbar ist. Fig. 2 shows a section in the longitudinal direction through a two-part squeegee. Here, the locking between the squeegee head 1 made of hard rubber and the lip 2 and the folding bridge 3 , each made of soft rubber, by a bead 5 , which can be locked with the head 1 is.
