Abstract

Since current wipers cannot cover the entire surface of a window pane of a motor vehicle even when two or more wiper blades are used which are arranged separately from one another, and since an obstruction to visibility even over a small area can impair road safety, it is proposed according to the invention to supply the areas of the window pane which are not covered by the wiper blades to compressed air and to clean them pneumatically.

Description

Scheibenwischer, insbesondere für die Windshield wipers, especially for those

Fensterscheiben eines Kraftfahrzeuges Die Erfindung betrifft einen Scheibenwischer, insbesondere für die Fensterscheiben eines Kraftfahrzeuges, nach dem Oberbegriff des Hauptanspruchs. Window panes of a motor vehicle The invention relates to a Windshield wipers, in particular for the window panes of a motor vehicle the preamble of the main claim.

Mit den bis jetzt bekanntgewordenen Ausfütrungsformen von Scheibenwischern ist es selbst bei Verwendung von zwei oder mehr Wischerblättern, die von zwei oder mehr räumlich voneinander getrennt angeordneten Wischerarmen betätigt werden, nicht möglich, die gesamte Oberfläche einer Fensterscheibe eines Kraftfahrzeuges zu erfassen.With the designs of windshield wipers that have become known up to now is it even when using two or more wiper blades by two or more more spatially separated wiper arms are operated, not possible to cover the entire surface of a window pane of a motor vehicle.

Da es bei der heutigen Verkehrsdichte nicht möglich ist, ein Kraftfahrzeug zur Reinigung von nicht gewischten Teilflächen einer Fensterscheibe nach Belieben anzuhalten, und da selbst eine kleinflächige Sichtbehinderung, beispielsweise die behinderte Sicht auf eine Verkehrsampel, verkehrsgefährdend sein kann, wird gemäß der Erfindung vorgeschlagen, die von den Wischerblättern nicht erfassten Teilflächen mit Druckluft zu beaufschlagen und pneumatisch zu säubern.Since it is not possible with today's traffic density, a motor vehicle For cleaning of un-wiped parts of a window pane at will to stop, and there even a small-area visual obstruction, for example the obstructed view of a traffic light, which can be hazardous to traffic, is according to proposed by the invention, the sub-areas not covered by the wiper blades to apply compressed air and to clean pneumatically.

Die der Erfindung zugrundeliegende Aufgabe ist durch die kennzeichnenden Merkmale der Patentansprüche gelöst.The object underlying the invention is through the characterizing Features of the claims solved.

In der Zeichnung ist eine mögliche Ausführungsform eines erfindungsgemäßen Scheibenwischers dargestellt, die im folgenden zusammen mit ihren Vorteilen näherlbeschrieben ist.In the drawing is a possible embodiment of an inventive Wipers shown, which are described in more detail below together with their advantages is.

Es zeigen 'in. 1 Fig. 1 die Außenansicht einer vorderen Fensterscheibe eines Kraftfahrzeuges mit nur einem Wischerblatt, das von einem einzigen, in der Mitte angeordneten Wischerarm betätigt wird, etwa im Maßstab 1:10, Fig.2 einen Teillängsschnitt durch das äußere Ende des Wischerblattes, etwa im Maßstab 2:1, Fig.3 einen Teillängsschnitt durch das innere Ende des Wischerblattes, etwa im Maßstab 2:1, und Fig.4 einen Querschnitt durch Fig.3.It show 'in. 1 Fig. 1 is the external view of a front Window pane of a motor vehicle with only one wiper blade, which is operated by a single, wiper arm arranged in the middle is actuated, approximately on a scale of 1:10, Fig. 2 a partial longitudinal section through the outer end of the wiper blade, approximately on a scale 2: 1, FIG. 3 a partial longitudinal section through the inner end of the wiper blade, for example on a scale of 2: 1, and Figure 4 shows a cross section through Figure 3.

Das an einem Wischerarm 1 befestigte Wischerblatt 2, welches aus einem hochfesten Kunststoff, beispielsweise Polyurethan, gefertigt ist, ist ein biegeelastisches Band, das sich allen Wölbungen der Fensterscheibe -gut anpassen kann.The attached to a wiper arm 1 wiper blade 2, which consists of a high-strength plastic, such as polyurethane, is made, is flexible Tape that can adapt well to all curvatures of the window pane.

Es ist fest verbunden mit der Wischlippe 3, die aus einem elastisch verformbaren Werkstoff, beispielsweise Gummi, gefertigt ist, und in der sich ein Hohlraum 4 befindet, in den Druckluft gepresst wird, die über düsenförmige Öffnungen 5, 6, 7 auf die Fensterscheibe 10 ausströmt. Diese düsenförmigen Öffnungen sind gegenüber der Fensterscheibe nur so wenig geneigt, daß ein mittlerer Anströmwinkel 13 von weniger als 300 zustandekommt, mit dessen Hilfe die Restflächen 12, die vom Wischerblatt nicht erreicht werden, pneumatisch gesäubert werden. Die pneumatische Säuberung entfernt bei trockener Witterung Ablagerungen von Staub und losen Schmutzteilen und bei Regen Tropfenbildungen, welche die Sicht des Fahrers so verzerren und behindern können, daß er Verkehrszeichen und Ampelsignale nur schlecht oder garnicht erkennen kann. Da die Druckluft von einer Wärmequelle des Kraftfahrzeuges, beispielsweise der Heizungsanlage, erwärmt- werden kann, bleibt im Winter die gesamte Oberfläche der Fensterscheibe auch bei langen Fahrten während eines dichten Schneetreibens schnee- und eisfrei, und und die sehr unangenehme Bildung von Eisklumpen an den Enden heutiger Wischerblätter, die nur von Hand entfernt werden können, wird verhindert.It is firmly connected to the wiper lip 3, which consists of an elastic deformable material, such as rubber, is made, and in which a Cavity 4 is located into which compressed air is pressed through nozzle-shaped openings 5, 6, 7 flows out onto the window pane 10. These are nozzle-shaped openings inclined only so little compared to the window pane that a medium angle of attack 13 of less than 300 comes about, with the help of which the remaining areas 12, which from Wiper blade cannot be reached, cleaned pneumatically. The pneumatic Cleaning removes dust deposits and loose dirt particles in dry weather and when it rains, drops form, which distort and obstruct the driver's view that he can only recognize traffic signs and traffic light signals poorly or not at all can. Since the compressed air from a heat source of the motor vehicle, for example the heating system, can be heated, the entire surface remains in winter the window pane even on long journeys in heavy snowdrifts free of snow and ice, and and the very uncomfortable formation of ice lumps at the ends of today's wiper blades, which can only be removed by hand prevented.

Die Einleitung der Druckluft in das Wischerblatt erfolgt über einen flexiblen Schlauch 14, der das innere Ende des Wischerblattes mit einer Druckluftquelle des Kraftfahrzeuges, beispielsweise der mit Überdruck arbeitenden Belüftungsanlage für den Innenraum oder dem Druckluftspeicher für die Bremsanlage, verbindet. Es ist natürlich auch möglich, hierfür einen eigenen Kompressor vorzusehen und die Druckluft mittels einer eigenen Wärmequelle, beispielsweise einem von der Batterie erwärmten Heizdraht, aufzuheizen. Das Wischerblatt 2, 3, welches nur die mittlere Fläche 11 mechanisch säubern kann, ist auswechselbar mit einem Halter 9 verbunden, der scharnierartig am Wischerarm 1 befestigt ist.The compressed air is introduced into the wiper blade via a flexible hose 14 connecting the inner end of the wiper blade to a source of compressed air of the motor vehicle, for example the ventilation system working with excess pressure for the interior or the compressed air reservoir for the brake system, connects. It is of course also possible to provide a separate compressor and the Compressed air by means of its own heat source, for example one from the battery heated heating wire to heat up. The wiper blade 2, 3, which only the middle Can mechanically clean surface 11, is interchangeably connected to a holder 9, which is attached to the wiper arm 1 in a hinge-like manner.
