Description

Die Erfindung betrifft ein Antriebsgetriebe für einen Treibstangenbeschlag eines Fensters, einer Fenstertür oder dergleichen, mit einer antreibbaren Nuss und einem durch Drehung der Nuss antreibbaren Getriebe zum Antrieb einer Treibstange, mit einem ersten Hebel und mit einem an dem ersten Hebel schwenkbar gelagerten zweiten Hebel des Getriebes, wobei die Hebel zu einem Kniehebel angeordnet sind und die Hebel mit einen in einer Kulisse geführten Kurbelzapfen verbunden sind.The invention relates to a drive gear for a drive rod fitting a window, a French window or the like, with a drivable nut and a driven by rotation of the nut gear for driving a drive rod, with a first lever and with a pivotably mounted on the first lever second lever of the transmission wherein the levers are arranged to a toggle lever and the levers are connected to a guided in a backdrop crank pin.

Die JP H08 82140 A offenbart ein Antriebsgetriebe mit einer von einer Nuss antreibbaren Hebelanordnung. Mehrere Zapfen der Hebelanordnung sind in einer Führung geführt. Die Hebelanordnung lässt sich durch Antrieb einer Nuss von einer gestreckten Position in eine zusammengezogene Position bewegen.The JP H08 82140 A discloses a drive gear having a lever arrangement drivable by a nut. Several pins of the lever assembly are guided in a guide. The lever assembly can be moved by driving a nut from an extended position to a contracted position.

Ein solches Antriebsgetriebe ist beispielsweise aus der EP 2 366 855 B1 bekannt. Bei diesem Antriebsgetriebe 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.Such a drive gear is for example from the EP 2 366 855 B1 known. In this drive 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.

Aus der EP 0 534 089 B1 ist ebenfalls 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 also known a drive gear 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.

Man könnte daran denken, mit einem weiteren Getriebe die Nachteile des Kurbeltriebs zu beseitigen und den Verschiebeweg der Treibstange bei der Drehbewegung der Nuss frei zu wählen. Dies führt jedoch zu sehr großen Abmessungen des Antriebsgetriebes. Da in einem Fenster oder einer Fenstertür nur sehr wenig Bauraum vorhanden ist, muss das Antriebsgetriebe besonders kleine Abmessungen aufweisen.One could think of eliminating the disadvantages of the crank mechanism with a further transmission and to freely choose the displacement of the drive rod during the rotational movement of the nut. However, this leads to very large dimensions of the drive gear. Since in a window or a French window only very little space is available, the drive gear must have particularly small dimensions.

Der Erfindung liegt das Problem zugrunde, ein Antriebsgetriebe der eingangs genannten Art so weiter zu bilden, dass es eine freie Übersetzung der Antriebsbewegung der Treibstange bei der Drehung der Nuss ermöglicht und besonders kleine Abmessungen aufweist.The invention is based on the problem, a drive gear of the type mentioned so on to form that allows a free translation of the drive movement of the drive rod during the rotation of the nut and has particularly small dimensions.

Dieses Problem wird erfindungsgemäß dadurch gelöst, dass 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.This problem is inventively solved in that the backdrop 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.

Durch diese Gestaltung lässt sich die Übersetzung der Antriebsbewegung der Treibstange bei der Drehung der Nuss durch einen geeigneten Verlauf der Kulisse einfach einstellen. Die Bewegungen der Hebel werden über den Kurbelzapfen von dem Verlauf der Kulisse gesteuert. Ein vorgesehenes Übersetzungsverhältnis zwischen Nuss und der Bewegung des Teilstücks der Treibstange lässt sich beispielsweise über das Längenverhältnis der Hebel und der Art des Antriebs der Hebel über die Nuss einfach einstellen. Damit weist das Antriebsgetriebe zudem besonders geringe Abmessungen auf. Das Antriebsgetriebe ermöglicht eine besonders leichtgängige Verriegelung des Treibstangenbeschlages, weil 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 Antriebsgetriebe 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.With this design, the translation of the drive movement of the drive rod during rotation of the nut can be easily adjusted by a suitable course of the scenery. The movements of the levers are controlled via the crank pin by the course of the backdrop. An intended gear ratio between nut and the movement of the portion of the drive rod can be easily adjusted, for example, on the ratio of the length of the lever and the nature of the drive of the lever on the nut. Thus, the drive gear also has particularly small dimensions. The drive gear allows a particularly smooth locking of the espagnolette fitting, because the backdrop 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 drive 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 crank pin is guided by the second section of the gate, the drive via the nut has a much greater translation, so that at the same rotational movement of the nut, the drive rod much stronger is moved. 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.

Das Antriebsgetriebe gestaltet sich gemäß einer vorteilhaften Weiterbildung der Erfindung besonders kompakt, wenn die Nuss ein Antriebsritzel hat, wenn das Antriebsritzel mit einem Schieber gekoppelt ist und wenn der erste Hebel an dem Schieber angelenkt und der zweite Hebel ein Lager zur Anlenkung an der Treibstange hat. Über die Größe des Antriebsritzels lässt sich zudem der Verschiebeweg des Schiebers in Abhängigkeit von der Drehung der Nuss und damit das Übersetzungsverhältnis des Antriebsgetriebes einstellen.The drive gear designed according to an advantageous embodiment of the invention is particularly compact when the nut has a drive pinion, when the drive pinion is coupled to a slider and when the first lever hinged to the slider and the second lever has a bearing for articulation on the drive rod. The size of the drive pinion can also adjust the displacement of the slide in response to the rotation of the nut and thus the transmission ratio of the drive gear.

Zur weiteren Verringerung der Abmessungen des Antriebsgetriebes trägt es gemäß einer anderen vorteilhaften Weitebildung der Erfindung bei, wenn der Schieber auf der Treibstange geführt ist und eine Reihe von Ausnehmungen hat, in die das Antriebsritzel eingreift.To further reduce the dimensions of the drive gear, it contributes according to another advantageous development of the invention, when the slide is guided on the drive rod and has a series of recesses into which the drive pinion engages.

Einer der Hebel könnte beispielsweise einen Vorsprung als Kurbelzapfen aufweisen, mit dem er in der Kulisse geführt ist. Das Antriebsgetriebe 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 drive 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.

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.A proposed path of the drive rod can be easily adjusted according to another advantageous embodiment of the invention, when the backdrop 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 Antriebsgetriebe lässt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung in besonders flach gestalteten Ausnehmungen des Fensters anordnen, wenn ein Teilstück der Treibstange wannenförmig zur Aufnahme des Schiebers gestaltet ist.The drive gear can be arranged according to another advantageous embodiment of the invention in particularly flat-shaped recesses of the window, when a portion of the drive rod is designed like a trough for receiving the slide.

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 Antriebsgetriebe eine besonders hohe Stabilität auf.The spatial allocation of the bearing of the nut and the leadership of the crank pin can be easily determined according to another advantageous embodiment of the invention, 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 a bearing shell for the nut and has a recess for the backdrop. With this design, the drive gear on a particularly high stability.

Zur Vereinfachung des Aufbaus des Antriebsgetriebes trägt es gemäß einer anderen vorteilhaften Weiterbildung der Erfindung bei, wenn das Gehäuse jeweils eine Führung für den Schieber und für die 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 Antriebsgetriebes bei.To simplify the structure of the drive gear, it contributes according to another advantageous embodiment of the invention, when the housing has a guide for the slide and for 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 drive gear.

For articulation has the first lever 15 a bearing 24 on the slider 14 and the second lever 16, a bearing 25 on the portion of the drive rod. 7

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 Antriebsgetriebes 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 90 ° in the position "D", you get to the in FIG. 3 Here, the crank pin 20 is 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 reaches 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 Antriebsgetriebe 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 Antriebsgetriebe 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 drive 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 drive gear 9 has a constant gear and a constant force curve.

Figur 5 zeigt den Verlauf der Übersetzung I des Antriebsgetriebes 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 Antriebsgetriebe 9 eine konstante Übersetzung. Bewegt man ausgehend von der Stellung "D" das Antriebsgetriebe 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 drive gear 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", the drive gear 9 has a constant ratio. Moving from the position "D" the drive gear 9 in the direction of the locking position "Z" is first achieved a very high gear ratio, which means that initially takes place at a low rotation of the nut 11, a large displacement of the drive rod 7. 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.
