Description
Die Erfindung geht aus von einem Wischblatt nach der Gattung des Hauptanspruchs. Bei den bekannten Wischblättern ist nur durch dauernde, kritische Betrachtung des Wischfeldes auf den Zustand der für die Wischqualität verantwortlichen Wischleiste zu schließen. Da sich diese jedoch vom Tag ihres Einsatzes am Kraftfahrzeug an alleine durch die Einwirkung von Umwelteinflüssen auch ohne die mechanische Beanspruchung während des Wischbetriebes täglich ver schlechtert, wird dies in vielen Fällen vom Fahrer des Kraftfahr zeuges nicht bemerkt. Es können sich deshalb, insbesondere bei Nachtfahrten mit Blendung durch Gegenverkehr kritische Situationen ergeben, deren eigentliche Ursachen in der mangelnden Qualität der Wischarbeit des Wischblattes begründet ist.The invention is based on a wiper blade of the genus Main claim. With the known wiper blades is only through continuous, critical observation of the wiping field on the condition of the close the wiper strip responsible for the wiping quality. There however, from the day of their use on the motor vehicle solely through the influence of environmental influences, even without the mechanical stress daily during wiping operation deteriorates, in many cases the driver of the motor vehicle not noticed. It can therefore, especially at Night driving with glare from oncoming traffic critical situations arise, the real causes of which are the poor quality of the Wiping the wiper blade is justified.
Das erfindungsgemäße Wischblatt mit den kennzeichnenden Merkmalen des Hauptanspruchs hat demgegenüber den Vorteil, daß durch die Farb änderung des Kunststoffteils dem Fahrer klar das Alter der Wisch leiste signalisiert wird, so daß dieser einen sicheren Anhaltspunkt zum Wechseln des Wischblattes hat. The wiper blade according to the invention with the characteristic features the main claim has the advantage that the color Changing the plastic part clearly shows the driver the age of the wipe bar is signaled so that this is a safe clue for changing the wiper blade.
Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vor teilhafte Weiterbildungen und Verbesserungen des im Hauptanspruch angegebenen Wischblatts möglich.The measures listed in the subclaims provide for partial further training and improvements of the main claim specified wiper blade possible.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung darge stellt und in der nachfolgenden Beschreibung näher erläutert. Es zeigenAn embodiment of the invention is shown in the drawing represents and explained in more detail in the following description. It demonstrate
Fig. 1 ein Wischblatt in Ansicht, mit einem als Indikator für die Einsatzdauer des Wischblatts dienenden Kunststoffteil, Fig. 2 das Kunststoffteil gemäß Fig. 1 in Seitenansicht, vergrößert dar gestellt, und Fig. 3 ein Schaubild, welches die Stärke der Farb änderung des Kunststoffteils über einen bestimmten Zeitraum veran schaulicht. Fig. 1 is a wiper blade in view, with a serving as an indicator of the service life of the wiper blade plastic part, Fig. 2 shows the plastic part of FIG. 1 in side view, and Fig. 3 is a graph showing the strength of the color change of Plastic part visualized over a certain period of time.
Ein in Fig. 1 dargestelltes Wischblatt 10 weist ein als Träger für eine Wischleiste 12 dienendes Tragbügelgestell 14 auf. Die Wisch leiste 12 ist aus Gummi oder einem gummiähnlichen Material her gestellt. Dieses Material leidet jedoch unter den auf dieses ein wirkenden Umwelteinflüssen. Diese setzen sich beispielsweise zusam men aus Wärme, Kälte, Straßenschmutz, Öl) UV-Strahlung usw. Es hat sich über viele Jahre gezeigt, daß eine solche Wischleiste im Laufe von etwa sechs Monaten so stark altert, daß mit dieser kein ord nungsgemäßes Wischergebnis zu erreichen ist. Die Folgen davon sind auf der Scheibe zurückbleibende Schlieren und Wassertröpfchen, wel che bei Nachtfahrten mit Gegenverkehr zu Streulicht und damit zur Blendung des Fahrers führen. Da diese Alterung alleine durch visuel len Augenschein kaum wahrnehmbar ist, liegt es an dem Fahrer des Kraftfahrzeuges, das Wischergebnis kritisch zu betrachten und aus dem sich daraus ergebenden Ergebnis die richtigen Schlüsse zu ziehen. An illustrated in Fig. 1 wiper blade 10 includes serving as a support for a wiper strip 12 carrying handle frame 14. The wiper strip 12 is made of rubber or a rubber-like material. However, this material suffers from the environmental influences acting on it. These are composed, for example, of heat, cold, dirt, oil) UV radiation, etc. It has been shown over many years that such a wiper strip ages so much over the course of about six months that it does not result in a proper wiping result to achieve. The consequences of this are streaks and droplets of water remaining on the windshield, which lead to stray light when driving at night with oncoming traffic and thus dazzle the driver. Since this aging is hardly noticeable by visual inspection alone, it is up to the driver of the motor vehicle to take a critical look at the wiping result and to draw the correct conclusions from the resultant result.
Um den Fahrer bei der Lösung dieses Problems zu unterstützen ist an dem Wischblatt ein Kunststoffteil 16 angeordnet, das aus einem Ma terial hergestellt ist, dessen Farbe sich unter Einwirkung von zu mindest einem der erwähnten Umwelteinflüsse im Laufe von etwa sechs Monaten so stark verändert, daß dies dem Fahrer auffällt und dieser notwendigen Wischblattwechsel vornimmt. Beim Ausführungsbeispiel ist das Kunststoffteil 16 an einem Bügel des Tragbügelgestells 14 ver rastet. Dazu weist das Kunststoffteil 16 an seiner Unterseite aus lenkbare Rasthaken 18 auf (Fig. 2), die unter Auffederung durch Durchbruche 20 in einem Tragbügelgestellteil hindurchgreifen. Es ist jedoch auch denkbar, das Kunststoffteil an dem Tragbügelgestell 14 des Wischblatts 10 anzukleben. Das Kunststoffteil kann, wie beim Ausführungsbeispiel dargestellt, als Blättchen ausgebildet sein.In order to assist the driver in solving this problem, a plastic part 16 is arranged on the wiper blade, which is made of a material, the color of which changes so much over the course of about six months under the influence of at least one of the above-mentioned environmental influences that the driver notices this and carries out the necessary wiper blade change. In the embodiment, the plastic part 16 is latched ver on a bracket of the bracket frame 14 . For this purpose, the plastic part 16 has on its underside made of steerable latching hooks 18 ( FIG. 2) which, when springing open, reach through openings 20 in a bracket frame part. However, it is also conceivable to glue the plastic part to the bracket frame 14 of the wiper blade 10 . The plastic part can, as shown in the embodiment, be designed as a leaflet.
Es ist jedoch genausogut denkbar, das Kunststoffteil als Folie aus zubilden und an dem Wischblatt 10 zu befestigen. Damit das Kunst stoffteil 16 nicht schon während der Lagerhaltung des Wischblatts eine Farbänderung erfährt, kann dieses beispielsweise mit einer ab nehmbaren Abdeckung überdeckt sein, die dann entfernt wird, wenn das Wischblatt am Kraftfahrzeug eingesetzt wird.However, it is equally conceivable to form the plastic part as a film and to fasten it to the wiper blade 10 . So that the plastic part 16 does not experience a color change already during the storage of the wiper blade, this can be covered, for example, with a removable cover, which is then removed when the wiper blade is used on the motor vehicle.
In Fig. 3 ist in einem Koordinatensystem dargestellt, wie sich die auf der Ordinate aufgetragene Farbänderung im Hinblick auf einen auf der Abszisse aufgetragenen Zeitraum vollzieht. Ausgehend von einer Ausgangsfarbe "X" zu einer Endfarbe "Y" vollzieht sich die Farb änderung gemäß einem ersten Ausführungsbeispiel, vom Tag des Ein satzes "E" zu einem Zeitpunkt "Z" von sechs Monaten nach E stetig (vgl. die strichpunktierte Linie 30 in Fig. 3). Ein besonders gün stiger Verlauf der Farbänderung ist mit der in Fig. 3 gestrichelt aufgetragenen Linie 40 dargestellt. Dort ist die Farbänderung wäh rend der ersten sechs Monate nach E gering. Danach allerdings er folgt eine rasche Änderung der Farbe des Kunststoffteils 16, die so stark ist, daß der Fahrer diese praktisch nicht übersehen kann. Diese dann erreichte Farbe "Y" bleibt im Idealfall erhalten und erinnert den Fahrer ununterbrochen an den fälligen Wischblatt wechsel.In Fig. 3 is shown in a coordinate system, such as the composition applied to the ordinate color change is taking place with respect to a period of time plotted on the abscissa. Starting from an initial color "X" to a final color "Y", the color change takes place according to a first exemplary embodiment, from the day of use "E" at a time "Z" of six months after E (see dash-dot line 30 in Fig. 3). A particularly favorable course of the color change is shown with the line 40 shown in broken lines in FIG. 3. There the color change is slight during the first six months after E. After that, however, he follows a rapid change in the color of the plastic part 16 , which is so strong that the driver can practically not miss it. This color "Y", which is then reached, is ideally retained and reminds the driver of the due wiper blade change without interruption.
