Abstract

A vehicle windscreen wiper arm (5) has a wiper blade (3,7) in contact with the screen. An adjusting mechanism lifts the wiper blade from the screen and leaves the wiper arm, which is formed as a scraper, in contact with the screen. ADVANTAGE - The wiper arm assembly is able to both remove rain and snow, ice, insects etc.

Description

Die Erfindung bezieht sich auf eine Scheibenreini­ gungsvorrichtung gemäß dem Oberbegriff des Patentan­ spruchs 1.The invention relates to a disc cleaning supply device according to the preamble of the patent saying 1.

Es wird beispielsweise in der Deutschen Patentschrift 24 05 484 eine derartige Scheibenreinigungsvorrich­ tung beschrieben, bei der jedoch das Entfernen von nicht flüssigem Schmutz, wie generell bei derartigen Vorrichtungen, problematisch ist.It is for example in the German patent 24 05 484 such a window cleaning device tion described, but in which the removal of non-liquid dirt, as is generally the case with such Devices, is problematic.

Der Erfindung liegt die Aufgabe zugrunde, eine Scheibenreinigungsvorrichtung der eingangs genannten Art zu schaffen, die unter allen Umständen wirksam ist.The invention has for its object a Window cleaning device of the aforementioned Kind of creating that is effective in all circumstances is.

Diese Aufgabe wird durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.This task is characterized by the characteristics of claim 1 solved.

Durch die Erfindung wird erreicht, daß in einer ersten Funktion der Wischerarm auf der Scheibe aufliegt. Der als Schaber ausgebildete Wischerarm kann Schnee, Eis oder Insekten von der Scheibe abkratzen. Ist das Fahrzeug abgestellt und der Wischerarm liegt direkt auf der Scheibe auf, ist das Wischblatt entlastet und es werden Wischblatt­ verformungen vermieden. In der zweiten Funktion liegt das Wischblatt auf der Scheibe auf und es kann Wasser von der Scheibe entfernt werden. The invention ensures that in one first function of the wiper arm on the window lies on. The wiper arm designed as a scraper can remove snow, ice or insects from the window scrape off. Is the vehicle parked and the Wiper arm lies directly on the window, that's it Wiper blade relieved and there will be wiper blade deformations avoided. The second function is the wiper blade on the window and there may be water be removed from the disc.  

Eine konstruktiv vorteilhafte Ausgestaltung der Erfindung ergibt sich, wenn der Hohlkörper ein u-förmiges Profil aufweist. Darin kann das Wisch­ blatt geschützt untergebracht sein. Wenigstens einer der beiden Schenkel des Hohlkörpers dient als Scha­ ber.A constructively advantageous embodiment of the Invention arises when the hollow body is a has a U-shaped profile. That can wipe it sheet protected. At least one the two legs of the hollow body serve as Scha about.

Der Hohlkörper kann in seiner Längserstreckung mit Einkerbungen versehen sein. Windschutzscheiben sind in der Regel gekrümmt. Ein derartiger Wischerarm kann sich auch gekrümmten Scheiben während seiner Bewegung anpassen.The hollow body can with in its longitudinal extent Notches should be provided. Windshields are usually curved. Such a wiper arm can also curved discs during its movement to adjust.

Eine vorteilhafte Ausgestaltung des Wischblattes ist, wenn das Wischblatt ein in seinem Durchmesser, z. B. durch Druckänderung beim Aufblasen, veränderliches Hohlrohr aufweist. Wird das Hohlrohr aufgeblasen, fährt das Wischblatt aus dem Wischerarm heraus. Der Wischerarm wird von der Scheibe abgehoben. Der beschriebene konstruktive Aufbau ist besonders einfach.An advantageous embodiment of the wiper blade is if the wiper blade has a diameter, e.g. B. due to pressure change when inflating, changeable Has hollow tube. If the hollow tube is inflated, drives the wiper blade out of the wiper arm. The The wiper arm is lifted off the window. The described construction is special easy.

Die erfindungsmäßige Scheibenreinigungsvorrichtung ist anhand der Zeichnung weiter erläutert. Es zeigenThe inventive window cleaning device is further explained using the drawing. Show it

Fig. 1 eine perspektivische Ansicht der er­ findungsmäßigen Scheibenreinigungs­ vorrichtung, Fig. 1 is a perspective view of the device he invention standard disc cleaning,

Fig. 3 das in Fig. 2 dargestellte Wischblatt im ausgefahrenen Zustand. Fig. 3 shows the wiper blade shown in Fig. 2 in the extended state.

Ein in Fig. 1 gezeigter Wischerarm 1 weist ein u-förmiges Profil 2 auf. Das u-förmige Profil 2 nimmt ein Wischblatt 3 auf. In seiner Längserstreckung ist der Wischerarm 1 mit Einkerbungen 4 versehen. Die Schenkel des Wischerarmes 1 sind als Schaber 5 ausgebildet. Das Wischblatt 3 besteht aus einem Hohlrohr 8 mit einer Wischlippe 7. Das Hohlrohr 6 ist in Fig. 2 in einem drucklosen Zustand dargestellt und liegt zusammengefaltet in dem U-Profil 2. Das Wischblatt 3 ist um die Höhe i von der in der Zeich­ nung nicht dargestellten Scheibe abgehoben. Fig. 3 zeigt das Hohlrohr 6 im aufgeblasenen Zustand. Der Schaber 5 ist um die Höhe h von der in der Zeichnung nicht dargestellten Scheibe abgehoben. Das Wischblatt 3 liegt auf der Scheibe auf.A shown in FIG. 1, the wiper arm 1 comprises a U-shaped profile 2 on. The U-shaped profile 2 receives a wiper blade 3 . In its longitudinal extent, the wiper arm 1 is provided with notches 4 . The legs of the wiper arm 1 are designed as a scraper 5 . The wiper blade 3 consists of a hollow tube 8 with a wiper lip 7 . The hollow tube 6 is shown in an unpressurized state in FIG. 2 and is folded up in the U-profile 2 . The wiper blade 3 is lifted by the height i from the disc not shown in the drawing. Fig. 3 shows the hollow tube 6 in the inflated state. The scraper 5 is raised by the height h from the disc, not shown in the drawing. The wiper blade 3 lies on the window.

Die erfindungsmäßige Scheibenreinigungsvorrichtung besitzt zwei verschiedene Funktionen. In einem ersten Zustand liegt der Schaber 5 auf einer nicht darge­ stellten Windschutzscheibe auf und erfüllt die erste Funktion. (vgl. Fig. 2) Bei seiner Bewegung über die Windschutzscheibe entfernt der Schaber 5 Schnee, Eis oder Insekten. Bei abgestelltem Fahrzeug erfährt das Wischblatt keine Anpreßkraft gegen die Windschutzscheibe. In einem zweiten Zustand (vgl. Fig. 3) ist das Hohlrohr 6 des Wischblattes 3 aufgeblasen und erfüllt die zweite Funktion. Das Wischblatt 3 liegt auf der Windschutzscheibe auf. Bei seiner Bewegung über die Windschutzscheibe kann Wasser von der Scheibe entfernt werden.The window cleaning device according to the invention has two different functions. In a first state, the scraper 5 rests on a windshield (not shown) and fulfills the first function. (cf. Fig. 2) When moving over the windshield, the scraper 5 removes snow, ice or insects. When the vehicle is parked, the wiper blade is not pressed against the windshield. In a second state (see FIG. 3), the hollow tube 6 of the wiper blade 3 is inflated and fulfills the second function. The wiper blade 3 lies on the windshield. When moving over the windshield, water can be removed from the windshield.

Anstelle einer durch Formänderung des Wischblattes zwischen den beiden Funktionen umschaltbaren Schei­ benreinigungsvorrichtung, kann das Wischblatt auch mechanisch als Ganzes gegenüber dem Wischerarm in Richtung der Scheibe verstellt werden und damit anstelle des Wischerarmes auf der Scheibe in Auflage gebracht werden.Instead of one by changing the shape of the wiper blade switchable switch between the two functions cleaning device, the wiper blade can also mechanically as a whole against the wiper arm in Be adjusted in the direction of the disc and thus instead of the wiper arm on the window in support to be brought.
