Description

Fensterhebegetriebe mit zwei Stellhebeln auf Zahnrädern, die durch ein dazwischenliegendes Antriebsglied bewegt werden Die Erfindung betrifft ein Fensterhebegetriebe mit zwei Stellhebeln auf Zahnrädern, die durch ein dazwischenliegendes Antriebsglied bewegt werden.Window lift gear with two levers on gears that go through an intermediate drive member are moved. The invention relates to a window lift mechanism with two adjusting levers on gears that are driven by an intermediate drive element be moved.

Fensterhebegetriebe dieser Art sind bereits bekannt, doch sind dieselben von recht umständlicher Bauart und erfordern besondere Bremsvorrichtungen. Bei den bekannten Einrichtungen erfolgt das Ausschwenken der beiden mit je einem Zahnrade verbundenen Stellhebel, z. B. durch eine Zahnstange, die durch einen Winkelhebel mittels eines in seiner Gleitbahn beweglichen Handknopfgriffes verschoben wird. Oder der Antrieb des einen Stellhebelzahnrades erfolgt durch ein besonders kleines Zahnrad, während das andere Stellhebelzahnrad mit dem ersten Stellhebelrad kämmt. Bei einer anderen Ausführungsform werden besondere Entlastungsfedern für das Spiel der wirksamen Teile erforderlich.Window lift drives of this type are already known, but are the same of quite cumbersome design and require special braking devices. Both known devices, the pivoting of the two takes place with one gear each associated control lever, e.g. B. by a rack, which is controlled by an angle lever is moved by means of a hand knob handle movable in its slideway. Or the drive of one adjusting lever gear is carried out by a particularly small one Gear, while the other lever gear meshes with the first lever wheel. In another embodiment, special relief springs are used for the game of the effective parts required.

Demgegenüber sind Bauart und Wirkungsweise des Erfindungsgegenstandes überaus einfach. Bei der neuen Vorrichtung sind die zum Antrieb der Stellhebel dienenden Zahnräder als Schneckenräder ausgebildet und haben eine zwischen denselben angeordnete gemeinsame Antriebsschnecke, die durch einen Schraubenradantrieb in Umdrehung versetzt wird. Einen ganz besonderen Vorteil bietet das neue Fensterhebegetriebe durch den Fortfall irgendwelcher Bremsvorrichtungen.In contrast, the design and mode of operation of the subject matter of the invention very easy. In the new device, the actuating levers are used to drive them Gears designed as worm gears and have one arranged between them common drive worm, which is set in rotation by a helical gear drive will. The new window lift mechanism offers a very special advantage thanks to the Elimination of any braking devices.

Das den Gegenstand der Erfindung bildende Fensterhebegetriebe ist auf der Zeichnung in einem Ausführungsbeispiel veranschaulicht.The window lifting gear forming the subject of the invention is illustrated on the drawing in one embodiment.

Abb. i zeigt das Stellhebelgetriebe in Ansicht.Fig. I shows the control lever gear in view.

Abb. 2 ist der entsprechende Grundriß. Auf der Grundplatte i sind die beiden Schneckenräder 2 und 3 mittels der Bolzen 4. und 5 drehbar gelagert. Der Antrieb der Schneckenräder :2 und 3 erfolgt durch den Schraubenradantrieb 6, 7 und die gemeinsame Antriebsschnecke B. Das Schraubenrad 7 und die Antriebsschnecke 8 sind in den beiden Lagenn 9- und io- drehbar.- Zum. Antrieb des Schraubenrades 6 dient eine Handkurbel i i. Die beiden Schneckenräder 2 und 3 drehen sich in entgegengesetzter Richtung und bewegen die beiden Stellhebel 12 und 13, welche das Fenster mittels der beiden Gleitrollen 1q., 15 anheben. Der Stellhebel 13 ist mit dem Schneckenrad 3 fest verbunden. Der Stellhebel 12 dagegen ist auf dem Schneckenrad 2 derart befestigt, daß er in der Drehrichtung verstellt werden kann, damit das Fenster stets richtig auf den Gleitrollen rd., 15 aufliegt. An der Handkurbel i i ist eine Verkleidungsrosette 16 vorgesehen.Fig. 2 is the corresponding floor plan. On the base plate i are the two worm wheels 2 and 3 are rotatably mounted by means of bolts 4 and 5. The worm gears: 2 and 3 are driven by the helical gear drive 6, 7 and the common drive worm B. The helical gear 7 and the drive worm 8 can be rotated in the two positions 9 and io. Drive of the helical gear 6 is a hand crank i i. The two worm wheels 2 and 3 rotate in opposite directions Direction and move the two adjusting levers 12 and 13, which the window means of the two castors 1q., 15. The adjusting lever 13 is with the worm wheel 3 firmly connected. The adjusting lever 12, however, is attached to the worm wheel 2 in such a way that that it can be adjusted in the direction of rotation so that the window is always correct 15 rests on the sliding rollers. There is a cover rosette on the hand crank i i 16 provided.

Das von den Gleitrollen 1q. und 15 frei getragene Schiebefenster wird durch die beiden Stellhebel 12, 13 unmittelbar in der Weise gehoben und gesenkt, daß die mit den Stellhebeln verbundenen Triebräder 2, 3 von der Antriebsschnecke 8 in Drehung versetzt werden, wenn letztere mittels der Handkurbel i i bzw. des Schraubenrades 6 gedreht wird.That of the castors 1q. and 15 freely supported sash windows raised and lowered directly by the two adjusting levers 12, 13, that the drive wheels 2, 3 connected to the adjusting levers from the drive worm 8 are set in rotation when the latter by means of the hand crank i i or des Helical wheel 6 is rotated.
