Description

Die Erfindung betrifft ein Übersetzungsgetriebe für einen Treibstangenbeschlag eines Fensters, einer Fenstertür oder dergleichen, mit einer antreibbaren Nuss und einem mit der Nuss gekoppelten Getriebe zum Antrieb einer Treibstange.The invention relates to a transmission gear for a drive rod fitting a window, a French window or the like, with a drivable nut and coupled to the nut gear for driving a drive rod.

Ein solches Übersetzungsgetriebe ist beispielsweise aus der EP 2 366 855 B1 bekannt. Bei diesem Übersetzungsgetriebe steht der erste Hebel von der Nuss ab, während der zweite Hebel an einem Schieber angelenkt ist. Die beiden Hebel bilden damit einen Kurbeltrieb zum Antrieb des Schiebers. Der Schieber treibt ein Zahnrad an, welches wiederum ein Teilstück der Treibstange antreibt. Stehen die Hebel in einem rechten Winkel zueinander, wird der Schieber und damit die Treibstange bei einer festgelegten Auslenkung der Nuss weiter bewegt, als bei einer nahezu gestreckten Anordnung der Hebel zueinander. Ein vorgesehener Verlauf der Bewegung der Treibstange über die Drehbewegung der Nuss lässt sich hierdurch nicht einstellen. Nachteilig bei dem bekannten Übersetzungsgetriebe ist die hohe Anzahl an Bauteilen, da das Getriebe in Antriebsrichtung hinter dem Kurbeltrieb angeordnet ist. Eine vorgesehene Übersetzung des Getriebes erfordert zudem einen großen Hebelarm des Kurbeltriebs und damit sehr großen Bauraum.Such a transmission gear is for example from the EP 2 366 855 B1 known. In this transmission gear, the first lever is from the nut, while the second lever is hinged to a slider. The two levers thus form a crank mechanism for driving the slider. The slider drives a gear, which in turn drives a portion of the drive rod. Stand the levers at a right angle to each other, the slider and thus the drive rod at a predetermined deflection of the nut is moved further than with a nearly extended arrangement of the lever to each other. A planned course of movement of the drive rod on the rotational movement of the nut can not be adjusted thereby. A disadvantage of the known transmission gear is the high number of components, since the transmission is arranged in the drive direction behind the crank mechanism. A proposed translation of the transmission also requires a large lever arm of the crank mechanism and thus very large space.

Aus der EP 0 534 089 B1 ist ein Antriebsgetriebe bekannt, bei dem zwei Hebel zu einem Kurbeltrieb zusammengestellt und von einer Nuss antreibbar sind. Über diesen Kurbeltrieb wird ein die Treibstange kämmendes Ritzel angetrieben. Der Verschiebeweg der Treibstange ist sehr stark abhängig von der Drehstellung der Nuss.From the EP 0 534 089 B1 is a drive gear known in which two levers are assembled into a crank mechanism and driven by a nut. About this crank drive a drive rod meshing pinion is driven. The displacement of the drive rod is very much dependent on the rotational position of the nut.

Der Erfindung liegt das Problem zugrunde, ein Antriebsritzel der eingangs genannten Art so weiter zu bilden, dass es einen besonders geringen Bauraum aufweist.The invention is based on the problem, a drive pinion of the type mentioned so on to form that it has a very small space.

Dieses Problem wird erfindungsgemäß dadurch gelöst, dass das Getriebe zwischen einem Schieber und der Treibstange angeordnet ist und ein Übersetzungsverhältnis ungleich 1:1 aufweist, dass die Nuss ein Antriebsritzel hat, dass das Antriebsritzel mit dem Schieber gekoppelt ist und der Schieber auf der Treibstange geführt ist und eine Reihe von Ausnehmungen hat, in die das Antriebsritzel eingreift.This problem is inventively solved in that the transmission is arranged between a slide and the drive rod and a ratio not equal to 1: 1, that the nut has a drive pinion, that the drive pinion is coupled to the slide and the slide is guided on the drive rod and has a series of recesses into which the drive pinion engages.

Durch diese Gestaltung hat das Übersetzungsgetriebe mit dem Getriebe und mit dem von dem Antriebsritzel angetriebenen Schieber zwei hintereinander angeordnete Einrichtungen, mit jeweils einem eigenen Übersetzungsverhältnis ungleich 1:1. Damit lässt sich der Weg der Treibstange über die Drehung der Nuss einfach festlegen. Das Übersetzungsverhältnis des Antriebsritzels gegenüber dem Schieber hängt von dem Radius des Antriebsritzels ab. Da die gesamte Übersetzung des Übersetzungsgetriebes auch von dem Getriebe erfolgt, lässt sich das Antriebsritzel mit besonders kleinen Abmessungen versehen. Dies trägt zu der besonders geringen Bauhöhe des Übersetzungsgetriebes bei.By this design, the transmission gear with the gear and the driven by the drive pinion slide two successively arranged devices, each with its own gear ratio unequal 1: 1. This makes it easy to set the path of the drive rod via the rotation of the nut. The ratio of the drive pinion relative to the slider depends on the radius of the drive pinion. Since the entire translation of the transmission gear is also carried by the transmission, the drive pinion can be provided with particularly small dimensions. This contributes to the particularly low overall height of the transmission.

Unterschiedliche Geschwindigkeiten beim Antrieb der Treibstange lassen sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung einfach erzeugen, wenn das Getriebe einen ersten Hebel und einen an dem ersten Hebel schwenkbar gelagerten zweiten Hebel hat, wenn die Hebel zu einem Kniehebel angeordnet sind und wenn die Hebel einen in einer Kulisse geführten Kurbelzapfen aufweisen.Different speeds when driving the drive rod can be easily produced according to another advantageous embodiment of the invention, when the transmission has a first lever and a second lever pivotally mounted on the second lever, when the levers are arranged to a toggle lever and when the lever in a have a backdrop guided crank pin.

Das Übersetzungsgetriebe gestaltet sich gemäß einer vorteilhaften Weiterbildung der Erfindung besonders kompakt, wenn der erste Hebel an dem Schieber angelenkt und der zweite Hebel ein Lager zur Anlenkung an der Treibstange hat.The transmission gear is designed according to an advantageous embodiment of the invention is particularly compact when the first lever hinged to the slide and the second lever has a bearing for articulation on the drive rod.

Einer der Hebel könnte beispielsweise einen Vorsprung als Kurbelzapfen aufweisen, mit dem er in der Kulisse geführt ist. Das Übersetzungsgetriebe gestaltet sich jedoch gemäß einer anderen vorteilhaften Weiterbildung der Erfindung konstruktiv besonders einfach, wenn ein die beiden Hebel miteinander verbindender Lagerzapfen einstückig mit dem Kurbelzapfen gefertigt ist.One of the levers could, for example, have a projection as a crank pin with which it is guided in the backdrop. However, the transmission gear designed according to another advantageous embodiment of the invention structurally particularly simple when a two levers interconnecting bearing pin is made in one piece with the crank pin.

Das Übersetzungsgetriebe ermöglicht gemäß einer anderen vorteilhaften Weiterbildung der Erfindung eine besonders leichtgängige Verriegelung des Treibstangenbeschlages, wenn die Kulisse einen geneigt zur vorgesehenen Bewegungsrichtung der Treibstange angeordneten ersten Abschnitt und einen sich daran anschließenden, entgegengesetzt zu dem ersten Abschnitt geneigten zweiten Abschnitt hat. Durch diese Gestaltung hat das Übersetzungsgetriebe eine variable Übersetzung beim Antrieb der Treibstange. Ist der Kurbelzapfen im ersten Abschnitt der Kulisse geführt, erfolgt eine geringe Bewegung der Treibstange bei einer Drehbewegung der Nuss. Wird jedoch der Kurbelzapfen von dem zweiten Abschnitt der Kulisse geführt, hat der Antrieb über die Nuss eine deutlich größere Übersetzung, so dass bei der gleichen Drehbewegung der Nuss die Treibstange wesentlich stärker bewegt wird. Um den Antrieb des Treibstangenbeschlages besonders leichtgängig zu gestalten, lässt sich die Führung des Kurbelzapfens in dem ersten Abschnitt unmittelbar an der Schließstellung anordnen, wenn über die Bewegung der Treibstange mehrere Verschlüsse des Treibstangenbeschlages in die Verriegelungsstellung bewegt werden. In dem zweiten Abschnitt kann der Kurbelzapfen geführt werden, wenn die Verschlüsse voneinander getrennt sind, da in dieser Stellung ein Reibungswiderstand des Treibstangenbeschlages besonders gering ist.The transmission gear allows according to another advantageous embodiment of the invention, a particularly smooth locking of the espagnolette fitting when the scenery has an inclined to the intended direction of movement of the drive rod arranged first section and an adjoining, opposite to the first section inclined second section. By this design, the transmission gear has a variable ratio when driving the drive rod. If the crank pin is guided in the first section of the gate, there is little movement of the drive rod during a rotational movement of the nut. However, if the crankpin is guided by the second section of the gate, the drive via the nut has a much greater gear ratio, so that during the same rotational movement of the nut the drive rod is moved considerably more. In order to make the drive of the espagnolette fitting particularly smooth, the leadership of the crank pin can be arranged in the first section directly to the closed position when moved over the movement of the drive rod several closures of the espagnolette in the locked position. In the second section, the crank pin can be guided when the shutters are separated from each other, since in this position a frictional resistance of the espagnolette fitting is particularly low.

Ein vorgesehener Weg der Treibstange lässt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung einfach einstellen, wenn die Kulisse einen dritten parallel zur Bewegungsrichtung der Treibstange angeordneten Abschnitt hat, welcher sich an den zweiten Abschnitt anschließt. In dem dritten Abschnitt ist der Kurbelzapfen vorzugsweise geführt, wenn der Treibstangenbeschlag von einer Drehstellung in eine Kippstellung angetrieben wird.An intended path of the drive rod can be easily adjusted according to another advantageous embodiment of the invention, when the gate has a third arranged parallel to the direction of movement of the drive rod section, which adjoins the second section. In the third section, the crank pin is preferably guided when the drive rod fitting is driven from a rotational position to a tilted position.

Das Übersetzungsgetriebe lässt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung in besonders flach gestalteten Ausnehmungen des Fensters anordnen, wenn ein Abschnitt der Treibstange wannenförmig zur Aufnahme des Schiebers gestaltet ist.The transmission gear can be arranged in accordance with another advantageous embodiment of the invention in particularly flat-shaped recesses of the window, when a portion of the drive rod is designed trough-shaped for receiving the slider.

Die räumliche Zuordnung der Lagerung der Nuss und der Führung des Kurbelzapfens lässt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung einfach festlegen, wenn ein Gehäuse einen Gehäuseboden und einen Gehäusedeckel hat, wenn zumindest eines der Bauteile des Gehäusebodens oder des Gehäusedeckels eine Lagerschale für die Nuss und eine Ausnehmung für die Kulisse hat. Durch diese Gestaltung weist das Übersetzungsgetriebe eine besonders hohe Stabilität auf.The spatial allocation of the bearing of the nut and the leadership of the crank pin can be according to another advantageous embodiment of Determine the invention easily, if a housing has a housing bottom and a housing cover, if at least one of the components of the housing bottom or the housing cover has a bearing shell for the nut and a recess for the backdrop. By this design, the transmission gear on a particularly high stability.

Zur Vereinfachung des Aufbaus des Übersetzungsgetriebes trägt es gemäß einer anderen vorteilhaften Weiterbildung der Erfindung bei, wenn das Gehäuse jeweils eine Führung für den Schieber und für den Abschnitt der Treibstange hat. Vorzugsweise sind die Führungen von Abwinklungen zumindest eines der Bauteile des Gehäusebodens oder des Gehäusedeckels gebildet. Dies trägt zur weiteren Erhöhung der Stabilität des Übersetzungsgetriebes bei.To simplify the structure of the transmission gear, it contributes according to another advantageous embodiment of the invention, when the housing has a guide for the slide and for the portion of the drive rod. Preferably, the guides are formed by bends at least one of the components of the housing bottom or the housing cover. This contributes to further increase the stability of the transmission gearbox.

Die Kulisse 21 hat einen ersten, geneigt zur vorgesehenen Bewegungsrichtung des Teilstücks der Treibstange 7 angeordneten Abschnitt 28 und einen zweiten, entgegengesetzt zum ersten Abschnitt 28 geneigten Abschnitt 29. Ein dritter Abschnitt 30 der Kulisse 21 ist parallel zur Bewegungsrichtung des Teilstücks der Treibstange 7 angeordnet und schließt sich an den zweiten Abschnitt 29 an. Der Kurbelzapfen 20 befindet sich in der dargestellten Schließstellung am Ende des ersten Abschnitts 28.The link 21 has a first, inclined to the intended direction of movement of the portion of the drive rod 7 arranged portion 28 and a second, opposite to the first portion 28 inclined portion 29. A third section 30 of the link 21 is arranged parallel to the direction of movement of the portion of the drive rod 7 and joins the second section 29. The crank pin 20 is in the illustrated closed position at the end of the first section 28th

Dreht man die Handhabe 6 ausgehend von der Stellung aus Figur 2 um 90° in die Stellung "D", so gelangt man in die in Figur 3 dargestellte Drehstellung des Übersetzungsgetriebes 9. Hier befindet sich der Kurbelzapfen 20 an einem Ende des dritten, parallel zur Bewegungsrichtung der Treibstange 7 angeordneten Abschnitts 30. Bei dem Antrieb von der Schließstellung in die Drehstellung wird der Kniehebel 17 zunächst gestreckt, bis er das Ende des ersten geneigten Abschnitts 28 erreicht hat und wird anschließend bei der Bewegung über den zweiten geneigten Abschnitt 29 wieder angewinkelt. Damit variiert beim Antrieb des Teilstücks der Treibstange 7 über die Handhabe 6 die Übersetzung und damit der Kraftverlauf. Dieser Sachverhalt wird in der Beschreibung zu Figur 5 und Figur 6 näher erläutert.Turning the handle 6 starting from the position FIG. 2 by 90 ° in the position "D", you get to the in FIG. 3 Here, the crank pin 20 is located at one end of the third, parallel to the direction of movement of the drive rod 7 arranged portion 30. In the drive from the closed position to the rotational position of the toggle lever 17 is first stretched until it is the end of the first has reached inclined portion 28 and is then bent in the movement over the second inclined portion 29 again. Thus varies the drive of the section of the drive rod 7 via the handle 6, the translation and thus the force curve. This fact becomes apparent in the description FIG. 5 and FIG. 6 explained in more detail.

Dreht man ausgehend von der in Figur 3 dargestellten Drehstellung die Handhabe 6 in die Stellung "K", wird das Übersetzungsgetriebe 9 in die Kippstellung angetrieben, welche in Figur 4 dargestellt ist. Zwischen der Drehstellung und der Kippstellung wird der Kurbelzapfen 20 in dem parallel zur Bewegungsrichtung des Teilstücks der Treibstange 7 verfahren. Während dieser Bewegung wird der Kniehebel 17 nicht gestreckt oder angewinkelt, so dass das Übersetzungsgetriebe 9 eine konstante Übersetzung und einen konstanten Kraftverlauf hat.Turning from the in FIG. 3 illustrated rotary position the handle 6 in the position "K", the transmission gear 9 is driven in the tilted position, which in FIG. 4 is shown. Between the rotational position and the tilted position of the crank pin 20 is moved in parallel to the direction of movement of the portion of the drive rod 7. During this movement, the toggle lever 17 is not stretched or bent, so that the transmission gear 9 has a constant gear and a constant force curve.

Figur 5 zeigt den Verlauf der Übersetzung I des Übersetzungsgetriebes 9 beim Antrieb der Handhabe von der Stellung "Z" über die Stellung "D" in die Stellung "K". Zwischen der Stellung "K" und der Stellung "D" hat das Übersetzungsgetriebe 9 eine konstante Übersetzung. Bewegt man ausgehend von der Stellung "D" das Übersetzungsgetriebe 9 in Richtung der Verriegelungsstellung "Z" wird zunächst eine sehr hohe Übersetzung erreicht, was bedeutet, dass zunächst bei einer geringen Verdrehung der Nuss 11 eine große Verschiebung der Treibstange 7 erfolgt. Erst wenn sich der Kurbelzapfen 20 in dem ersten Abschnitt 28 der Kulisse 21 befindet, erfolgt der Antrieb des Teilstücks der Treibstange 7 mit einer geringen Übersetzung. Dies bedeutet, dass eine große Drehung der Nuss 11 nur zu einer kleinen Verschiebung des Teilstücks der Treibstange 7 führt. FIG. 5 shows the course of the ratio I of the transmission 9 when driving the handle from the position "Z" on the position "D" in the "K" position. Between the position "K" and the position "D" has the transmission gear 9 is a constant translation. Moving starting from the position "D" the transmission gear 9 in the direction of the locking position "Z" is first achieved a very high gear, which means that initially with a small rotation of the nut 11, a large displacement of the drive rod 7 takes place. Only when the crank pin 20 is in the first section 28 of the link 21, the drive of the portion of the drive rod 7 takes place with a low gear ratio. This means that a large rotation of the nut 11 only leads to a small displacement of the portion of the drive rod 7.

Figur 6 zeigt zur Verdeutlichung den Verlauf der Längsbewegung x des Teilstücks der Treibstange 7 bei der Verdrehung der Nuss 11 über die Stellungen "K", "D" und "Z". FIG. 6 shows for clarity the course of the longitudinal movement x of the portion of the drive rod 7 in the rotation of the nut 11 on the positions "K", "D" and "Z".

Die niedrige Übersetzung vor der Stellung "Z" führt im montierten Zustand dazu, dass Reibungskräfte der in Figur 1 dargestellten Verschlüsse 8 einfach überwunden werden können. Außerhalb der Schließstellung setzen die Verschlüsse 8 dem Antrieb der Treibstange 7 keine Reibungskräfte entgegen, so dass in diesen Stellungen der Antrieb mit einer hohen Übersetzung erfolgen kann.The low ratio before the position "Z" in the assembled state causes friction forces in the FIG. 1 shown closures 8 can be overcome easily. Outside the closed position, the closures 8 set the drive of the drive rod 7 no frictional forces, so that in these positions the drive can be done with a high translation.
