Description

Die Neuerung betrifft einen Scheibenwischer, insbesondere für Kraftfahrzeuge.The innovation relates to a windshield wiper, in particular for motor vehicles.

Nach dem heutigen Stande der Technik wird die Windschutzscheibe eines über Nacht in> Freien abgestellten Kraftfahrzeuges am Morgen vor Antritt der Fahrt mit einem Besen vom lockeren Schnee befreit und das Wegschaben einer angefrorenen Schnee- und Eisschicht erfolgt mittels eines aus Kunststoff gefertigten Schabers, dessen Räumkante wie eine Messerschneide geformt ist.According to the current state of the art, the windshield becomes one overnight in> Free parked motor vehicle in the morning before starting the journey The loose snow is removed with a broom and a frozen layer of snow and ice is scraped away by means of a plastic scraper, the clearing edge of which is shaped like a knife edge is.

Da diese Handarbeit bei großer Kälte und weiter anhaltendem Schneefall unangenehm ist, wird sie meist mit | Ärger und ohne die Sorgfalt verrichtet, die zum Ver- | meiden von Kratzspuren auf der Glasoberfläche notwendig ist. Gemäß der Neuerung wird daher vorgeschlagen, die heute notwendige Handarbeit maschinell und so schonend erledigen zu lassen, daß Beschädigungen der Glasoberfläche mit Sicherheit vermieden werden. Dabei j soll als Reinigungsmaschine der Scheibenwischer ver- ISince this manual work is uncomfortable when it is very cold and snow continues to fall, it is usually done with | Trouble and done without the care necessary to | it is necessary to avoid scratches on the glass surface is. According to the innovation, it is therefore proposed that the manual work required today be done by machine and such to be done gently so that damage to the glass surface is avoided with certainty. Here j the windshield wiper is supposed to be used as a cleaning machine

Die der Neuerung zugrundeliegende Aufgabe der Gestaltung eines solchen speziellen Winter- WischerblattesThe task on which the innovation is based is the design of such a special winter wiper blade

Winter- Wischerblätter gemäß der Neuerung sind in ihrer Funktion so leicht zu verstehen, daß sich eine über die Zeichnung und die Schutzansprüche hinausgehende Erklärung erübrigt. Sie haben eine lange Lebensdauer, ein geringes Gewicht und bei einem ästhetischen Aussehen eine hohe Funktionstüchtigkeit. Sie bieten dem Fahrer eines Kraftfahrzeuges außer der Bequemlichkeit, das Beseitigen eines angefrorenen Schnee- und Eisbelages geschützt im Wageninneren abwarten zu können, noch den Vorteil, Fahrten bei dichtem Schneetreiben ohne das heute damit verbundene Sicherheitsrisiko absolvieren zu können.Winter wiper blades according to the innovation are so easy to understand in their function that one on the Drawing and explanation going beyond the protection claims are not required. They have a long lifespan, a short one Weight and high functionality with an aesthetic appearance. They offer the driver of a motor vehicle besides the convenience of eliminating one The advantage of being able to wait for frozen snow and ice cover inside the car is still protected, while driving in heavy snowstorms without being able to complete the safety risk associated with it today.
