Abstract

A windscreen wiper, whereby the water which is wiped in a downwards direction by said wiper is removed before the relative wind can convey it in an upwards direction into the field of vision of the driver. The rain water wiped from the windscreen is suctioned by means of a perforated tube which is arranged parallel to the wiper blade. A flexible tube line redirects the water to the suction unit and the roadway.

Description

Nach Stand der Technik dient der bei Regen eingeschaltete Scheibenwischer dazu, die Front­ scheibe des Fahrzeugs immer wieder von den die Sicht störenden Regentropfen bzw. Wasseran­ sammlungen zu befreien. Dabei wird das Regenwasser zur Seite bzw. nach unten gewischt und fließt bei langsamer Fahrt bodenwärts ab.According to the state of the art, it serves when it rains switched on wipers to the front disc of the vehicle again and again disturbing raindrops or water free collections. The rainwater wiped to the side or down and flows in slow downhill ride.

Der Erfindung liegt das Problem zugrunde, daß bei höherer Fahrgeschwindigkeit (ab ca. 80 km/h) das gerade nach unten gewischte Regenwasser durch den Fahrtwind jedoch nach oben und außen gedrückt wird mit der Folge, daß es nicht nach unten abfließen kann, sondern zum großen Teil durch den starken Fahrtwind auf die Frontscheibe zurückgeblasen wird und die Sicht behindert. The invention is based on the problem that higher driving speed (from approx. 80 km / h) rainwater just wiped down through the Airstream however is pushed up and out with the result that it doesn't drain down can, but largely through the strong Head wind is blown back onto the windscreen and obscures the view.  

Dieses Problem wird gelöst
This problem is solved

  • 1. durch eine an der unteren Seite des Wischerblattes angebrachten Absaugvorrichtung. Diese führt das während des Wischvorgangs gesammelte Regenwasser mittels eines dicht und paralell am Wischerblatt angebrachten perforierten Kunststoffröhrchens (s. Abb. 1) über eine flexible Schlauchleitung (durch den Motorraum) zur Fahrbahn hin ab.1. through a suction device attached to the lower side of the wiper blade. This drains the rainwater collected during the wiping process through a perforated plastic tube attached to the wiper blade (see Fig. 1) in parallel and via a flexible hose (through the engine compartment) to the road.

Diese Absaugung kann erfolgenThis suction can take place

  • 1. durch eine manuell oder elektronisch zuschalt­ bare Absaugpumpe, wie sie beispielsweise als Sekret­ absaugpumpe in der Notfallmedizin verwendet wird. Diese Pumpe wird elektrisch über die Fahrzeugbatterie betrieben und kann im Motorraum montiert werden. Die elektronische Zuschaltung erfolgt durch Koppelung von Scheibenwischertätigkeit und Fahrgeschwindigkeit z. B. über 80 km/h.1. by manually or electronically switching on bare suction pump, such as as a secretion suction pump is used in emergency medicine. This pump is powered electrically from the vehicle battery operated and can be installed in the engine compartment. The electronic connection is made by coupling of wiper activity and driving speed e.g. B. over 80 km / h.

Die Absaugung kann auch erfolgenThe suction can also be done

  • 1. rein mechanisch/physikalisch durch Ausnutzung des Fahrtwindes. Hierbei wird an der Karosserieunterseite im Frontbereich des Fahrzeugs ein spitzwinkliger Metalltrichter so angebracht, daß er vom Fahrtwind durchströmt wird. Am Ende des Trichters ragen mehrere angeschrägte Metallröhrchen spitzwinklig derart in den Luftstrom, daß in den Röhrchen ein Unterdruck und Sog entsteht (s. Abb. 2). Durch einen Schlauch sind diese Metallsaugröhrchen mit den perforierten Kunststoffröhrchen am Scheibenwischer verbunden.1. purely mechanical / physical by utilizing the airstream. Here, an acute-angled metal funnel is attached to the underside of the body in the front area of the vehicle so that the airstream flows through it. At the end of the funnel, several beveled metal tubes protrude into the air flow at an acute angle such that a vacuum and suction is created in the tubes (see Fig. 2). These metal suction tubes are connected to the perforated plastic tubes on the wiper by a hose.

Der Sog im Trichter wird umso größer, je höher die Fahrtgeschwindigkeit und je stärker der Fahrtwind ist. So wird die Wasserabsaugung gerade dann effektiv, wenn das Wasserproblem entsteht.The higher the suction, the greater the suction in the funnel Travel speed and the stronger the wind is. So the water suction becomes effective when the water problem arises.

  • 1. durch eine in Höhe der Scheibenwischerblätter auf der Scheibe aufgeklebten Kunststoffleiste (s. Abb. 3). Diese Leiste wird über die gesamte Breite der Frontscheibe so angebracht, daß die Wischer­ blätter in Ausgangsstellung auf ihr zu liegen kommen (s. Abb. 4). Im Bereich der aufliegenden Wischer­ blätter ist die Leiste mit schrägen Schlitzen perforiert, durch die das nach unten gewischte Regenwasser in eine Rinne gelangt (s. Abb. 5).1. by a plastic strip glued to the window at the height of the wiper blades (see Fig. 3). This bar is attached over the entire width of the windscreen so that the wiper blades come to rest on it in the starting position (see Fig. 4). In the area of the overlying wiper blades, the strip is perforated with oblique slots through which the rainwater wiped down reaches a channel (see Fig. 5).

In dieser Rinne wird das Wasser durch den Fahrtwind und bedingt durch die vorgegebene Wölbung der Frontscheibe zur Seite nach außen gedrückt, wo es ohne Sichtbehinderung des Fahrers abfließen kann. Die aus durchsichtigem Kunststoffmaterial bestehende Leiste ist ca. 3 cm breit. Am oberen Ende flach der Scheibe anliegend, erhebt sie sich ca. 1 cm wie eine Sprungschanze über das Niveau der Scheibe, um dadurch die Rinne zu bilden (s. Abb. 6).In this channel, the water is pushed outwards by the wind and due to the curvature of the windscreen, where it can drain off without obstructing the driver's view. The bar made of transparent plastic material is about 3 cm wide. Lying flat against the disc at the upper end, it rises about 1 cm above the level of the disc like a ski jump to form the gutter (see Fig. 6).

Diese Vorrichtung setzt voraus, daß die Scheiben­ wischer und somit auch die Leiste im Luftstrom des Fahrtwindes liegen.This device requires that the washers wiper and thus also the bar in the air flow of the Airstream.

Das heißt, daß die Kraft des Fahrtwindes, die das eben weggewischte Regenwasser wieder auf die Frontscheibe drückt, durch die oben beschriebene Vorrichtung auch die Ableitung dieses Wassers gewährleistet; völlig energieneutral und elektronisch nicht störanfällig.That means that the force of the airstream, that just wiped rainwater back onto the windscreen presses through the device described above as well ensures the drainage of this water; completely energy-neutral and not susceptible to electronic interference.

(Die angegebenen Werkstücke können in Form und Material variieren). (The specified workpieces can be in shape and Material vary).  

Es wird Schutz begehrt für die gesamte Regenwasser­ ableitungsanlage, d. h. für perforiertes Röhrchen, Schlauchsystem und Absaug-Wind-Trichter einerseits sowie für die Regenwasserableitungsleiste anderer­ seits.Protection is sought for all of the rainwater drainage system, d. H. for perforated tubes, Hose system and suction wind funnel on the one hand as well as for the rainwater drainage strip of others on the part of

Die Ableitung des Wassers hat den Vorteil, daß die Sicht bei Regen nicht mehr durch Wasser behindert wird, welches durch den Fahrtwind von der Unterseite des Scheibenwischerblattes wieder auf die Frontscheibe hochgedrückt wird; die Sicht wird klarer. Die Folge ist eine deutlich höhere Fahrsicher­ heit gerade bei schwierigen Wetterbedingungen, was sich bei breiter Anwendung in Kraftfahrzeugen positiv auf die Unfallstatistik auswirken wird.The drainage of the water has the advantage that the view in rain no longer through water is hindered by the wind from the Underside of the wiper blade back on the Windscreen is pushed up; the view becomes clearer. The result is significantly higher driving safety what, especially in difficult weather conditions widely used in motor vehicles will have a positive impact on accident statistics.

Gewerbliche Anwendbarkeit für die Regenwasserableit­ anlage besteht durch den möglichen Einbau in alle Fahrzeuge mit Scheibenwischern (s. Abb. 7).There is commercial applicability for the rainwater drainage system due to the possible installation in all vehicles with windshield wipers (see Fig. 7).
