Abstract
Description
Ein Scheibenwischer, den wir für unerere PKW, LKW, Flugzeuge und andere Fahrzeuge benötigen, um uns eine freie Sicht durch die Windschutzscheibe beim Regen zu ermöglichen, ist Stand der Technik.A wiper that we use for our cars, trucks, planes and other vehicles need to give us a clear view through the To enable the windshield when it rains is state of the art.
Im Jahre 1908 wurde der Scheibenwischer von Prinz Heinrich von Preußen erfunden und angemeldet beim Deutschen Reichspatentamt unter der Patentnummer 2 04 343. Ein Scheibenwischer setzt sich zusammen aus einem Wischermotor, auf dem ein Arm unter einem Federdruck an dessen Ende ein Wischerarm gelenkig angebracht, in dem gleichzeitig ein Wischerblatt aus Gummi mit einer Mikrokante eingesetzt ist. Vom Wischerblatt aus Gummi wird das Wasser von der Scheibe abgestreift und mechanisch abgerieben. Außer der Qualität, modernen Aufmachung und der sogenannten Mikrokante an dem Wischerblatt hat sich im Wesentlichen nichts geändert. Durch die Mikrokante am Wischerblatt, die unter ständigem Druck auf die Scheibe gedrückt werden, ergibt sich guter Abrieb des Regens und damit gleichzeitig eine gute Sicht. Die Wischblätter werden relativ schnell durch den Staub und Schmutz verschlissen, so daß wir im Durchschnitt 1× in 6 Monaten die Wischer wechseln sollten. Weil die Sicht beim Regen ohnehin sehr schlecht ist, durch verschlissene Wischblätter wird es von der Sicherheit her bedrohlich das Geschehen auf der Straße auszumachen. Außerdem wird auch die Windschutzscheibe durch den feinen Staub und Schmutz beschädigt, was auch mit der Sicherheit zu tun hat, selbst bei Sonnenschein. Durch die Anwendung der Erfindung welche die dem Verschleiß unterliegende Mikrokante ersetzen soll, wird es möglich sein, den Scheibenwischer praktisch verschleißfrei auszuführen, gleichzeitig wird mehr Sicherheit beim Regen auf den Straßen garantieren und die Windschutzscheibe von Schleifspuren geschont werden. Anstatt der Gummi-Mikrokante verwendet man ein Luftpolster. Den neuen Scheibenwischer hat man sich so vorzustellen, daß er sich vom Aussehen her nur gering von den bisherigen unterscheidet. Die Erfindung beruht darauf, daß beim Einschalten des Scheibenwischers, durch Luftzufuhr von ca 2-4 Bar sich der Scheibenwischer gegen einen einstellbaren Anschlag, von der Windschutzscheibe nur einige Zehntel z. B. 0,1 Millimeter abhebt, dadurch sich ein Luftpolster bildet, welches das Wasser von der Scheibenfläche abstreift, so daß der Wischer über der Windschutzscheibe nur schweben wird. Das Wischblatt soll weiter aus Gummi oder ähnlichem Material bleiben. Bei einer Ausführung nach der Erfindung hat das Wischblatt konische Form mit einem länglichen Schlitz von ca. 0,1-0,2 Millimeter auf der ganzen Länge. Alle beiden Endstücke müssen zu sein. Eine weitere Ausgestaltung der Erfindung sieht vor, daß im Inneren eine Heizung vorgesehen wird, damit auch im Winter bei Vereisung einwandfreier Betrieb der Wischer gewährleistet ist. Nach erstmaligem Abschaben des Eises per Hand, bildet sich meistens sofort eine neue, hauchdünne Schicht von Eis, die durch erhitzte Luft vermieden werden kann. Durch den Schlitz im Wischer kann auch das Wasser für die Scheibenwischanlage mit einer Druckwasserpumpe geführt werden zum Reinigen der Windschutzscheibe. In 1908 Prince Heinrich von Prussia invented and registered at the German Reich Patent Office under the patent number 2 04 343. A windshield wiper is composed from a wiper motor on which an arm is under a spring pressure the end of which a wiper arm is articulated, in which a Wiper blade made of rubber with a micro edge is inserted. From Wiper blade made of rubber, the water is stripped from the window and rubbed mechanically. Except for the quality, modern presentation and the so-called micro edge on the wiper blade has in Essentially nothing changed. Through the micro edge on the wiper blade, that are pressed under constant pressure on the disc results good abrasion of the rain and at the same time a good view. The Wiper blades become dust and dirt relatively quickly worn out, so that we wiped the wipers on average 1 × in 6 months should change. Because the visibility in the rain is very bad anyway due to worn wiper blades, it becomes safe threatening to spot the action on the street. Besides, will also the windshield due to the fine dust and dirt damaged, which also has to do with security, even with Sunshine. By applying the invention which the Micro edge subject to wear, it will be possible run the wiper practically wear-free, at the same time will guarantee more safety when it rains on the roads and that Windshield to be protected from grinding marks. Instead of Rubber micro edge uses an air cushion. The new You have to imagine windshield wipers in such a way that they move away from the Appearance differs only slightly from the previous ones. The invention is based on the fact that when the windshield wiper is switched on, Air supply of about 2-4 bar the wiper against you adjustable stop, only a few tenths from the windshield e.g. B. lifts 0.1 millimeters, thereby forming an air cushion, which the water wipes off the window surface so that the wiper over the windshield will just float. The wiper blade should continue remain made of rubber or similar material. When running after According to the invention, the wiper blade has a conical shape with an elongated shape Slit of approximately 0.1-0.2 millimeters along the entire length. Both of them Tails need to be. Another embodiment of the invention provides that a heater is provided inside, so that in In winter, freezing of the wipers is guaranteed is. After scraping off the ice by hand for the first time, it forms usually immediately a new, wafer-thin layer of ice that passes through heated air can be avoided. Can through the slot in the wiper also the water for the windscreen wiper system with a Pressurized water pumps are led to clean the windshield.
Zum Wischer werden 2 Leitungen geführt, für Luft und für das Wasser der Scheibenwischeranlage. Es wird möglich sein entweder die Luft oder das Wasser einzuschalten. Der Scheibenwischer soll erst dann in Bewegung kommen, wenn sich der Druck aufgebaut hat und damit das Luft- oder Wasser-Polster gebildet hat.Two lines are routed to the wiper, for air and for the water Windscreen wiper system. It will be possible either the air or that Turn on water. Only then should the windshield wiper move come when the pressure has built up and thus the air or Water cushion has formed.
