Abstract

The arrangement has a window panel (2) which can slide in at least one guide (4,5), and a command generator for the sliding motion. A vibration generator (9), which generates relative vibrations between the panel and the guide which facilitate the sliding motion, is coupled to the command generator so that this triggers a vibration generation immediately before the sliding motion.

Description

Die Erfindung betrifft eine Fensteranordnung gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a window arrangement according to the preamble of the claim 1.

Betrachtet man den bevorzugten Einsatzfall der Erfindung, nämlich eine Seitenfensteranordnung eines Kraftfahrzeuges, so erfordert die Reibung zwischen Führung und Scheibe relativ große Verstellkräfte für die Verschiebebewegung der Scheibe in den seitlichen Führungen; diese Verstellkräfte müssen bei einer motorischen Betätigung der Scheibe von einem Elektromotor, andernfalls an der Handkurbel von der bedienenden Person aufgebracht werden. Bei der diesbezüglichen Auslegung des Antriebs muß beachtet werden, daß die erforderlichen Verstellkräfte - bei einer Seitenfensteranordnung eines Kraftfahrzeuges führt die Scheibe in der Regel senkrechte Bewegungen aus - nicht nur auf temperatur- und alterungsabhängige Reibungs-Maximalwerte ausgelegt werden müssen, sondern daß die aufzubringenden Verstellkräfte auch in der Lage sein müssen, die gewünschte Fensterverschiebebewegung im Winter bei Vereisung der Scheibe bzw. bei Verbindung der Scheibe mit der Führung durch Eisbrücken sicherzustellen.Consider the preferred application of the invention, namely one Side window arrangement of a motor vehicle, so requires the friction between the guide and disk relatively large adjustment forces for the sliding movement of the disk in the side guides; these adjustment forces must be when the motor is actuated Washer from an electric motor, otherwise on the hand crank from the operator Person can be upset. When designing the drive in this regard, the following must be observed be that the necessary adjustment forces - in a side window arrangement As a rule, the motor vehicle performs vertical movements - not only on temperature and age-dependent maximum friction values must be designed, but that the adjustment forces to be applied must also be able to Desired window sliding movement in winter when the window is iced up or at Ensure connection of the disc with the guide through ice bridges.

In der Beschreibungseinleitung der DE 43 31 790 C2, die sich mit der Verringerung von Quietschgeräuschen und damit Schwingungen während der Verschiebebewegungen einer Fensterscheibe befaßt, sind bekannte Fensterdichtungen für Türen von Kraftfahrzeugen angegeben, bei denen die Anpreßkraft der Dichtung an die Scheibe während der Scheibenbewegung verringert wird, damit der motorische Kraftaufwand für die Scheibenbewegung reduziert wird. Eine derartige Lösung dürfte aber kaum wirksam sein bei der beschriebenen Scheibenvereisung; außerdem ruft die angesprochene Verringerung der Anpreßkraft der Dichtung an die Scheibe die Gefahr der Undichtigkeit hervor.In the introduction to DE 43 31 790 C2, which deals with the reduction of Squeaking noises and thus vibrations during the shifting movements of a Window pane are known window seals for doors of motor vehicles specified, in which the contact pressure of the seal on the disc during the Disc movement is reduced so the motor effort for the Disc movement is reduced. Such a solution is unlikely to be effective the glazing described above; furthermore, the mentioned reduction in Contact pressure of the seal against the pane indicates the risk of leakage.

Zur Abrundung des Standes der Technik zum Thema Verringung der Reibung sei darauf hingewiesen, daß in Gruppe G12B3/06 der internationalen Patentklassifikation die Reibungsminderung durch Vibration bei ganz anderen Gegenständen, nämlich Meßinstrumenten, behandelt ist.To round off the state of the art on the subject of reducing friction, let it be pointed out that in group G12B3 / 06 of the international patent classification the Reduced friction due to vibration with completely different objects, namely Measuring instruments, is treated.

Der Erfindung liegt die Aufgabe zugrunde, eine gattungsgemäße Fensteranordnung zu schaffen, die mit einfachen bewährten Mitteln so ausgelegt ist, daß die Antriebskräfte für die Verschiebebewegungen der Scheibe gegenüber bekannten Fensteranordnungen sowohl hinsichtlich des Reibungsanteils als auch hinsichtlich eines auf eine Vereisung zurückzuführenden Anteils der erforderlichen Verstellkräfte verringert sind.The invention has for its object to a generic window arrangement create that is designed with simple proven means that the driving forces for the Sliding movements of the pane compared to known window arrangements both with regard to the proportion of friction as well as with regard to icing attributable portion of the required adjustment forces are reduced.

Die erfindungsgemäße Lösung dieser Aufgabe besteht in den kennzeichnenden Merkmalen des Hauptanspruchs, vorteilhafte Ausbildungen der Erfindung beschreiben die Unteransprüche.The achievement of this task consists in the characteristic features of the main claim, advantageous embodiments of the invention describe the Subclaims.

Die Erfindung reduziert sich also nicht auf den Einsatz von Schwingungen zur Reibungsverminderung, sondern sieht zwecks Berücksichtigung von auf Vereisung zurückzuführenden Verstellkräften eine bestimmte Reihenfolge des Wirksamwerdens des Schwingungserzeugers und des Antriebs vor. Bei einem Handantrieb für die Durchführung der Verschiebebewegungen der Scheibe, also üblicherweise einer Kurbel, kann dies dadurch geschehen, daß die Kugel einen bestimmten Leerlaufwinkel ausführt, zu Beginn dessen sie zwar den Schwingungserzeuger wirksam werden läßt, während sie die Verschiebebewegungen der Scheibe erst am Ende dieses Winkelbereichs auslöst. Bei einem elektrischen Antrieb für die Verschiebebewegungen der Scheibe, wie er zunehmend in modernen Kraftfahrzeugen Einsatz findet, kann zwischen der Handhabe, jetzt einem Schalter, einerseits und dem elektrischen Antriebsmotor für die Scheibenbewegungen andererseits ein Verzögerungsglied, beispielsweise nach Art eines ansprechverzögerten Relais, liegen, während die Verbindung zwischen Handhabe und Schwingungserzeuger, üblicherweise dann einem Piezowandler oder einem elektromagnetischen Schwinger, keine verzögernden Glieder enthält.The invention is therefore not reduced to the use of vibrations Reduction of friction, but for the purpose of taking into account icing adjusting forces to be traced back in a specific order of effectiveness of the Vibration generator and the drive. With a manual drive for the implementation the sliding movements of the disc, usually a crank, can do this happen by starting the ball at a certain idle angle of which it lets the vibrator take effect while it is Sliding movements of the disk are only triggered at the end of this angular range. At an electric drive for the sliding movements of the disc, as he increasingly in modern motor vehicles can be used between the handle, now one Switch, on the one hand and the electric drive motor for the disk movements on the other hand, a delay element, for example in the manner of a delayed response Relays, while the connection between the handle and the vibrator, then usually a piezo transducer or an electromagnetic oscillator, none contains delaying limbs.

Ein Ausführungsbeispiel für eine Fensteranordnung mit elektromotorischem Antrieb wird im folgenden anhand der Zeichnung erläutert.An embodiment of a window arrangement with an electric motor drive is in following explained with reference to the drawing.

Die einzige Figur zeigt eine Kraftfahrzeugtür 1 von innen nach Entfernung der üblichen inneren Abdeckung. Die Scheibe 2 ist in einer teilweise abgesenkten Stellung wiedergegeben; zwischen ihrer Schließstellung und einer noch weiter unten zu denkenden Öffnungsstellung ist sie mittels des Elektromotors 3 längs den Führungen 4 und 5 in der Tür 1 verschiebbar. Die Abtriebswelle des Elektromotors 3 trägt das Ritzel 6, das mit der Zahnstange 7 kämmt, die am unteren Rand der Scheibe 2 angreift, d.h. unterhalb der bei 8 angedeuteten Fensterbrüstung.The only figure shows a motor vehicle door 1 from the inside after removal of the usual inner cover. The disc 2 is in a partially lowered position reproduced; between its closed position and one to be thought of below It is in the open position by means of the electric motor 3 along the guides 4 and 5 in the door 1 movable. The output shaft of the electric motor 3 carries the pinion 6, which with the Rack 7 meshes, which acts on the lower edge of the disc 2, i.e. below that at 8 indicated parapet.

Ebenfalls in demjenigen Scheibenbereich, der auch bei geschlossener Scheibe unterhalb der Fensterbrüstung 8 und damit verdeckt liegt, erkennt man bei 9 einen Piezowandler als Schwingungserzeuger. Dem elektrischen Antriebsmotor 3 und dem Schwingungserzeuger 9 ist die als Taste ausgebildete Handhabe 10 gemeinsam zugeordnet, die bei ihrer Betätigung die Verbindung der Teile 3 und 9 mit der Bordbatterie 11 des Fahrzeugs herstellt.Also in the area of the pane below, even when the pane is closed of the window parapet 8 and is therefore covered, one recognizes a piezo transducer as 9 Vibrator. The electric drive motor 3 and the vibration generator 9 the handle 10 designed as a button is assigned together when it is actuated the connection of parts 3 and 9 with the on-board battery 11 of the vehicle.

Während nach Schließen des Kontaktes der Taste 10 der Schwingungserzeuger 9 sofort an Spannung gelegt wird und demgemäß die Scheibe 2 in hochfrequente Schwingungen versetzt, erfolgt die Erregung des Elektromotors 3 über das ansprechverzögerte Relais 12 mit seinem Kontakt 13 erst nach der Ansprechzeit des Relais 12 und damit verzögert.While the contact of the button 10 is closed, the vibration generator 9 turns on immediately Voltage is applied and accordingly the disc 2 in high-frequency vibrations offset, the excitation of the electric motor 3 takes place via the delayed relay 12 with its contact 13 only after the response time of the relay 12 and thus delayed.

Das bedeutet, daß während der Ansprechzeit des Relais 12 und damit vor Beginn der Verschiebebewegung der Scheibe 2 durch den Elektromotor 3 der Schwingungserzeuger 9 die Scheibe 2 in ihrem Ruhezustand bereits in hochfrequente Schwingungen versetzt, die dazu dienen,

Figure 00030001
Brücken" zwischen Scheibe 2 und Tür 1, gebildet beispielsweise durch Vereisung oder Verschmutzung, zu zerstören. Bei Beginn der Verschiebebewegung der Scheibe 2 relativ zur Tür 1 braucht der Elektromotor 3 demgemäß keine Kräfte zur Zerstörung derartiger Brücken aufzubringen.This means that during the response time of the relay 12 and thus before the displacement movement of the disc 2 by the electric motor 3 of the vibration generator 9, the disc 2 in its idle state already sets high-frequency vibrations which serve to
Figure 00030001
To destroy bridges "between pane 2 and door 1, formed, for example, by icing or dirt. At the start of the sliding movement of pane 2 relative to door 1, electric motor 3 accordingly does not need to apply any forces to destroy such bridges.

Auch während des sich anschließenden Verschiebens der Scheibe 2 sind die vom Elektromotor 3 aufzubringenden Antriebskräfte für die Scheibe 2 deshalb nur niedrig, weil die Scheibe 2 nach wie vor schwingt und demgemäß die Reibung zwischen ihr und ihren Führungen 4 und 5 gleichsam ausgeklopft" wird.Even during the subsequent shifting of the disk 2, the driving forces to be applied by the electric motor 3 for the disk 2 are only low because the disk 2 still vibrates and accordingly the friction between it and its guides 4 and 5, as it were knocked out ".

Die beschriebenen erfindungsgemäßen Maßnahmen wirken sich insofern besonders vorteilhaft aus, als der Elektromotor 3 oder allgemein: der Antrieb für die Verschiebebebewegungen der Scheibe 2 kleiner bemessen sein kann als bei den bekannten Fensteranordnungen. Das wiederum hat zur Folge, daß die Bordbatterie des Fahrzeuges weniger belastet wird. Ein ganz anderer Vorteil wiederum ist darin zu sehen, daß die so erzielte Reibungsreduzierung auch die Dynamik des Bewegungsvorganges der Scheibe 2 relativ zu ihren Führungen 4 und 5 verbessert, so daß die in der eingangs behandelten DE 43 31 790 C2 angesprochenen Quietschgeräusche nicht auftreten, sich also besondere Dämpfungsmaßnahmen gegen sie erübrigen.The measures according to the invention described have a particular effect in this respect advantageous from than the electric motor 3 or in general: the drive for the Sliding movements of the disc 2 can be made smaller than in the known Window arrangements. This in turn has the consequence that the vehicle's on-board battery is less burdened. Another advantage can be seen in the fact that the so achieved friction reduction also the dynamics of the movement process of the disc 2 improved relative to their guides 4 and 5, so that the DE discussed in the introduction 43 31 790 C2 squeaking noises occur, so special Dampening measures against them are unnecessary.
