Description
Die Erfindung betrifft ein Wischerblatt für Scheibenwischer anlagen, mit einem Grundkörper aus relativ hartem Kunststoff, der einen über seine Längserstreckung durchgehenden, im Querschnitt etwa T-förmigen, offenen Kanal zur Aufnahme des Fußbereichs eines im Querschnitt gleichfalls etwa T-förmigen, weichen Wischgummis, der beidseits vom Grund balken des ′T′ abragende Vorsprünge aufweist, mit denen er sich während der hin- und hergehenden Schwenkbe wegungen des Wischerblattes an Anschlagflächen des Grund körpers abstützt.The invention relates to a wiper blade for wipers plants, with a base made of relatively hard plastic, the one over its length, in Cross-section approximately T-shaped, open channel for receiving of the foot area is also approximately in cross section T-shaped, soft squeegees that are on both sides of the bottom beams of the 'T' protruding projections with which he during the back and forth swiveling movements of the wiper blade on the contact surfaces of the base body supports.
Ein derartiges Wischerblatt ist bereits der DE-OS 23 44 876 als bekannt zu entnehmen. Die dort dargestellte Abstützung des relativ weichen Wischgummis reicht jedoch nicht aus, um unter allen Betriebsbedingungen eine Schlierenbildung auf der zu wischenden Scheibenfläche zu verhindern.Such a wiper blade is already DE-OS 23 44 876 as known. The support shown there the relatively soft squeegee is not enough, to create streaks under all operating conditions on the window surface to be wiped.
Der vorliegenden Erfindung lag deshalb die Aufgabe zugrunde, ein gattungsgemäßes Wischerblatt so weiterzubilden, daß auch unter ungünstigen Bedingungen eine einwandfreie Scheibenreinigung erfolgt. The present invention was therefore based on the object to develop a generic wiper blade so that perfect even under unfavorable conditions Window cleaning is done.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Begrenzungsflächen des Kanals zu seinem offenen Mündungsbereich hin bogenförmig zurücktreten und in abge rundete Fußteile auslaufen, an denen sich die Oberseiten der Vorsprünge je nach Schwenkrichtung abwechselnd form schlüssig abstützen.This object is achieved in that the boundary surfaces of the channel to its open Step back towards the mouth in an arc and into Rounded foot parts run out, on which the tops the projections alternate shape depending on the direction of rotation support conclusively.
Die Abstützung des Wischgummis kann in vorteilhafter Aus gestaltung der Erfindung dadurch weiter verbessert werden, daß der Grundbalken des ′T′ des Wischgummis mindestens auf der Hälfte seiner Höhe innerhalb des Kanals verläuft.The support of the squeegee can be advantageous design of the invention can be further improved by that the base bar of the 'T' of the squeegee at least half of its height runs inside the canal.
Eine noch weitergehende Verbesserung in dieser Richtung kann schließlich noch dadurch erzielt werden, daß die Form der Begrenzungsflächen des Kanals und die Form des Wischgummis so aufeinander abgestimmt sind, daß der Wischgummi in beiden Schwenklagen möglichst weitgehend formschlüssig an den Begrenzungsflächen und den Fußteilen anliegt.A further improvement in this direction can can finally be achieved in that the shape of the Boundary surfaces of the channel and the shape of the squeegee are coordinated so that the squeegee in two pivot positions as far as possible form-fitting lies against the boundary surfaces and the foot parts.
Der Gegenstand der Erfindung soll im folgenden anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert werden.The subject matter of the invention is intended to be based on a shown in the drawing embodiment closer are explained.
In der Zeichnung zeigen:The drawing shows:
Fig. 1 einen Querschnitt durch ein Wischerblatt in seiner Mittellage, und Fig. 1 shows a cross section through a wiper blade in its central position, and
Fig. 2 eine Darstellung entsprechend der Fig. 1, jedoch bei in Richtung des Pfeiles ′P′ be wegtem Wischerblatt. Fig. 2 is a representation corresponding to FIG. 1, but in the direction of the arrow ' P ' be moved wiper blade.
Das in der Zeichnung dargestellte Wischerblatt weist einen Grundkörper 1 auf, der vorzugsweise aus einem Hart-PVC- Strangprofil besteht. Im Grundkörper 1 ist ein im Quer schnitt etwa T-förmiger, in der Zeichnung nach unten offener Kanal 2 vorgesehen, der der Aufnahme des Fußteils 3 eines im Querschnitt gleichfalls T-förmigen Wischgummis 4 dient, der vorzugsweise aus einem Elastomer-Strangprofil besteht. Um dem Wischerblatt eine gewünschte Vorspannung geben zu können, ist zwischen dem Fußteil 3 des Wischgummis 4 und dem Grund des Kanals 2 eine Stahlband-Einlage 5 vorge sehen.The wiper blade shown in the drawing has a base body 1 , which preferably consists of a hard PVC extruded profile. In the base body 1 is a cross-section approximately T-shaped, in the drawing downwardly open channel 2 is provided, which serves to receive the foot part 3 of a cross section likewise T-shaped squeegee 4 , which preferably consists of an elastomer extruded profile. In order to be able to give the wiper blade a desired pretension, a steel strip insert 5 is seen between the foot part 3 of the wiper blade 4 and the base of the channel 2 .
Der Grundkörper 1 des Wischerblattes ist in üblicher Weise durch Metallbügel 6 gehalten.The base body 1 of the wiper blade is held in the usual way by metal bracket 6 .
Die seitlichen Begrenzungsflächen 7 des Kanals 2 treten zu seinem offenen Mündungsbereich hin bogenförmig zurück und laufen in abgerundete Fußteile 8 aus. An die zurücktretenden Begrenzungsflächen 7 legt sich beim Verschwenken des Wischer blattes - wie in Fig. 2 der Zeichnung dargestellt - jeweils die zugeordnete Seite des Grundbalkens 9 des ′T′ des Wischgummis 4 an, während sich auf der Unterseite des Fußteils 8 die Oberseite eines jeweils zugeordneten, vom Grundbalken 9 des ′T′ abragenden Vorsprungs 10 abstützt.The lateral boundary surfaces 7 of the channel 2 arc back towards its open mouth area and run into rounded base parts 8 . At the receding boundary surfaces 7 , when pivoting the wiper blade - as shown in Fig. 2 of the drawing - each assigned side of the base bar 9 of the 'T' of the squeegee 4 , while on the underside of the foot part 8 the top of each assigned, supported by the base bar 9 of the 'T' protruding projection 10 .
Die vorstehend beschriebenen Bereiche von Grundkörper 1 und Wischgummi 4 sind dabei in ihrer Formgebung so ge staltet, daß beim Verschwenken eine möglichst weit gehende flächige Anlage der Teile aneinander erfolgt. The above-described areas of base body 1 and squeegee 4 are designed in their shape so that when pivoting as far as possible extensive contact of the parts takes place against each other.
In vorteilhafter Ausgestaltung der Erfindung kann der Grundkörper auf seiner Längserstreckung in der Zeich nung nicht dargestellte örtliche Aussparungen (Durch brüche) aufweisen, wodurch die Führung des Wischgummis weiter verbessert wird.In an advantageous embodiment of the invention, the Basic body on its longitudinal extent in the drawing local recesses not shown (through have breaks), thereby guiding the squeegee is further improved.
