Definitions

  • the invention relates to a transmission gear for a connecting rod fitting of a window, a balcony door or the like, with a drivable nut and a gear coupled to the nut for driving a connecting rod, the gear being arranged between a slide and the connecting rod and a gear ratio not equal to 1: 1 comprises that the nut has a drive pinion, that the drive pinion is coupled to the slide and has a series of recesses into which the drive pinion engages.
  • An edge gear with a drive pinion which has a further pinion for receiving the handle, is from the EP 1 533 453 A1 known.
  • a transmission gear is arranged between the two pinions and has a longitudinally displaceable coupling part which engages with the further pinion and is connected to the mounting of the drive pinion.
  • the drive rod section has several recesses, via which the drive pinion is in engagement with it.
  • One of the two drive pinions here has a square seat, whereas the second drive pinion engages on the one hand with a rolling toothing that is stationary in the housing and on the other hand with a longitudinally displaceable rack.
  • This rack engages in the drive rod via driver elements in order to move it.
  • a transmission for a lock which has arms rotatably mounted on racks.
  • the racks are arranged symmetrically on both sides around the handle of the transmission and the arms mounted on them engage in curved link guides on both sides.
  • the connecting slides have straight guides in which the arms engage and are thus moved along with the movement of the racks.
  • Such a transmission gear is, for example, from EP 2 366 855 B1 known.
  • the first lever protrudes from the nut, while the second lever is hinged to a slide.
  • the two levers thus form a crank mechanism for driving the slide.
  • the slide drives a gear, which in turn drives part of the drive rod. If the levers are at a right angle to one another, the slide and thus the drive rod are moved further with a fixed deflection of the nut than with an almost straight arrangement of the levers to one another. An intended course of the movement of the drive rod via the rotational movement of the nut cannot be set as a result.
  • the disadvantage of the known transmission gear is the large number of components, since the gear is arranged behind the crank mechanism in the drive direction. An envisaged translation of the transmission also requires a large lever arm of the crank drive and thus very large installation space.
  • the invention is based on the problem of developing a drive pinion of the type mentioned at the beginning in such a way that it has a particularly small installation space.

  • the transmission gear has a variable transmission ratio when driving the drive rod. If the crank pin is guided in the first section of the link, there is a slight movement of the drive rod when the nut rotates. If, however, the crank pin is guided by the second section of the link, the drive via the nut has a significantly greater translation, so that the drive rod is moved much more strongly with the same rotary movement of the nut.
  • the guide of the crank pin in the first section can be arranged directly at the closed position if several closures of the drive rod fitting are moved into the locking position via the movement of the drive rod.
  • the crank pin can be guided in the second section when the locks are separated from one another, since in this position the frictional resistance of the drive rod fitting is particularly low.
  • an intended path of the drive rod can be easily set if the link has a third section which is arranged parallel to the direction of movement of the drive rod and which adjoins the second section.
  • the crank pin is preferably guided in the third section when the connecting rod fitting is driven from a rotational position to a tilted position.
  • the transmission gear can be arranged in particularly flat recesses in the window if a section of the drive rod is trough-shaped for receiving the slide.
  • the spatial assignment of the bearing of the nut and the guide of the crank pin can easily be determined according to another advantageous development of the invention if a housing has a housing base and a housing cover, if at least one of the components of the housing base or the housing cover has a bearing shell for the nut and has a recess for the backdrop.
  • the transmission gear has a particularly high level of stability.
  • the housing has a guide for the slide and for the section of the drive rod.
  • the guides are preferably formed by bends of at least one of the components of the housing base or of the housing cover. This helps to further increase the stability of the transmission gear.

  • FIG 2 shows a transmission gear of the espagnolette 3 from Figure 1 in the closed position in which the handle 6 is in position "Z".
  • the transmission gear 9 has a nut 11 rotatably mounted in a housing 10 for attaching the in Figure 1 handle 6 shown and a portion of the drive rod 7.

  • Figure 5 shows the course of the translation I of the transmission gear 9 when the handle is driven from the “Z” position through the “D” position into the “K” position. Between the “K” position and the “D” position, the transmission gear 9 has a constant ratio. If, starting from position “D”, the transmission gear 9 is moved in the direction of the locking position “Z”, a very high transmission ratio is first achieved, which means that initially with a slight rotation of the nut 11 there is a large displacement of the drive rod 7. Only when the crank pin 20 is in the first section 28 of the link 21 is the portion of the drive rod 7 driven with a low gear ratio. This means that a large rotation of the nut 11 only leads to a small displacement of the section of the drive rod 7.
  • Figure 6 shows the course of the longitudinal movement x of the section of the drive rod 7 when the nut 11 is rotated through the positions "K", "D” and "Z".

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, wobei 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 eine Reihe von Ausnehmungen hat, in die das Antriebsritzel eingreift.The invention relates to a transmission gear for a connecting rod fitting of a window, a balcony door or the like, with a drivable nut and a gear coupled to the nut for driving a connecting rod, the gear being arranged between a slide and the connecting rod and a gear ratio not equal to 1: 1 comprises that the nut has a drive pinion, that the drive pinion is coupled to the slide and has a series of recesses into which the drive pinion engages.

Ein Kantengetriebe mit einem Antriebsritzel, welches ein weiteres Ritzel zur Aufnahme der Handhabe aufweist ist aus der EP 1 533 453 A1 bekannt. Zwischen den beiden Ritzeln ist ein Übersetzungsgetriebe angeordnet, das ein längs verschiebbares, mit dem weiteren Ritzel in Eingriff stehendes und mit der Lagerung des Antriebsritzel verbundenes Koppelteil aufweist. Weiterhin weist der Treibstangenabschnitt mehrere Ausnehmungen auf, über welche der Antriebsritzel mit ihm in Eingriff steht.An edge gear with a drive pinion, which has a further pinion for receiving the handle, is from the EP 1 533 453 A1 known. A transmission gear is arranged between the two pinions and has a longitudinally displaceable coupling part which engages with the further pinion and is connected to the mounting of the drive pinion. Furthermore, the drive rod section has several recesses, via which the drive pinion is in engagement with it.

Weiterhin ist aus der DE 12 44 611 B ein Getriebe bekannt, welches zwei Antriebsritzel aufweist, die über eine Antriebszahnstange miteinander verbunden sind. Eines der beiden Antriebsritzel weist hierbei eine Vierkantaufnahme auf, wohingegen das zweite Antriebsritzel einerseits mit einer, im Gehäuse, ortsfesten Abwälzverzahnung und andererseits mit einer längs verlagerbaren Zahnstange in Eingriff steht. Über Mitnehmerelemente greift diese Zahnstange in die Treibstange, um diese zu verlagern.Furthermore, from the DE 12 44 611 B a transmission known which has two drive pinions which are connected to one another via a drive rack. One of the two drive pinions here has a square seat, whereas the second drive pinion engages on the one hand with a rolling toothing that is stationary in the housing and on the other hand with a longitudinally displaceable rack. This rack engages in the drive rod via driver elements in order to move it.

Aus der WO 2004/083575 A1 ist ein Getriebe für ein Schloss bekannt, welches drehbar an Zahnstangen gelagerte Arme aufweist. Die Zahnstangen sind beidseitig symmetrisch um die Handhabe des Getriebes angeordnet und die an ihnen gelagerten Arme greifen beidseitig in bogenförmige Kulissenführungen ein. Hierdurch drehen sich die Arme bei einer Verlagerung der Zahnstangen, sodass sich die effektive Länge des Zahnstangen-Arm-Verbundes ändert. Die Anschlussschieber weisen gerade Führungen auf, in welche die Arme eingreifen und werden so, bei Bewegung der Zahnstangen, mitbewegt.From the WO 2004/083575 A1 a transmission for a lock is known which has arms rotatably mounted on racks. The racks are arranged symmetrically on both sides around the handle of the transmission and the arms mounted on them engage in curved link guides on both sides. As a result, the arms rotate when the racks are shifted, so that the effective length of the rack-arm assembly changes. The connecting slides have straight guides in which the arms engage and are thus moved along with the movement of the racks.

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 EP 2 366 855 B1 known. In this transmission, the first lever protrudes from the nut, while the second lever is hinged to a slide. The two levers thus form a crank mechanism for driving the slide. The slide drives a gear, which in turn drives part of the drive rod. If the levers are at a right angle to one another, the slide and thus the drive rod are moved further with a fixed deflection of the nut than with an almost straight arrangement of the levers to one another. An intended course of the movement of the drive rod via the rotational movement of the nut cannot be set as a result. The disadvantage of the known transmission gear is the large number of components, since the gear is arranged behind the crank mechanism in the drive direction. An envisaged translation of the transmission also requires a large lever arm of the crank drive and thus very large installation 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 a drive gear is known in which two levers are combined to form a crank mechanism and can be driven by a nut. A pinion meshing with the drive rod is driven via this crank mechanism. The displacement path of the connecting rod is very much dependent on the rotary 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 of developing a drive pinion of the type mentioned at the beginning in such a way that it has a particularly small installation space.

Dieses Problem wird erfindungsgemäß dadurch gelöst, dass der Schieber auf der Treibstange geführt istThis problem is solved according to the invention in that the slide is guided on the drive rod

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 Übersetzungsverhält-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.Due to this design, the transmission gear with the gear and with the slide driven by the drive pinion has two devices arranged one behind the other, each with its own transmission ratio to the intended direction of movement of the drive rod arranged first section and an adjoining, opposite to the first section inclined second section. As a result of this design, the transmission gear has a variable transmission ratio when driving the drive rod. If the crank pin is guided in the first section of the link, there is a slight movement of the drive rod when the nut rotates. If, however, the crank pin is guided by the second section of the link, the drive via the nut has a significantly greater translation, so that the drive rod is moved much more strongly with the same rotary movement of the nut. In order to make the drive of the drive rod fitting particularly smooth, the guide of the crank pin in the first section can be arranged directly at the closed position if several closures of the drive rod fitting are moved into the locking position via the movement of the drive rod. The crank pin can be guided in the second section when the locks are separated from one another, since in this position the frictional resistance of the drive rod 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.According to another advantageous development of the invention, an intended path of the drive rod can be easily set if the link has a third section which is arranged parallel to the direction of movement of the drive rod and which adjoins the second section. The crank pin is preferably guided in the third section when the connecting 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.According to another advantageous development of the invention, the transmission gear can be arranged in particularly flat recesses in the window if a section of the drive rod is trough-shaped 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 Übersetzungsgetriebe eine besonders hohe Stabilität auf.The spatial assignment of the bearing of the nut and the guide of the crank pin can easily be determined according to another advantageous development of the invention if a housing has a housing base and a housing cover, if at least one of the components of the housing base or the housing cover has a bearing shell for the nut and has a recess for the backdrop. As a result of this design, the transmission gear has a particularly high level of 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.According to another advantageous development of the invention, it helps to simplify the structure of the transmission gear if the housing has a guide for the slide and for the section of the drive rod. The guides are preferably formed by bends of at least one of the components of the housing base or of the housing cover. This helps to further increase the stability of the transmission gear.

The transmission gear 9 has a nut 11 rotatably mounted in a housing 10 for attaching the in Figure 1 handle 6 shown and a portion of the drive rod 7. The housing 10 has a housing bottom 26 arranged parallel to the plane of the drawing and a housing cover with a bearing shell (not shown) for mounting the nut 11, which is manufactured in one piece with the drive pinion 13. To simplify the drawing, the housing cover is not shown. The transmission gear 9 has a gear 12 with a drive pinion 13 arranged concentrically to the nut 11 for driving a slide 14 and with a toggle lever 17 formed by two levers 15, 16. The slide 14 has a series of recesses 18 which the drive pinion 13 meshes with . A first lever 15 of the toggle lever 17 is articulated on the slide 14, while the second lever 16 is articulated on the section of the drive rod 7.

The gate 21 is designed as a recess 27 in at least the housing bottom 26 of the housing 10. Furthermore, the housing 10 has a respective guide 22, 23 for the slide 14 and for the section of the drive rod 7. The slide 14 is guided on the section of the drive rod 7. The drive rod 7 is designed in the shape of a trough to accommodate the slide 14. For articulation, the first lever 15 has a bearing 24 on the slide 14 and the second lever 16 has a bearing 25 on the section 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 gate 21 has a first section 28 inclined to the intended direction of movement of the section of the drive rod 7 and a second section 29 inclined opposite to the first section 28. A third section 30 of the gate 21 is arranged parallel to the direction of movement of the section of the drive rod 7 and adjoins the second section 29. In the illustrated closed position, the crank pin 20 is located at the end of the first section 28.

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.If the handle 6 is rotated starting from the position Figure 2 by 90 ° into the "D" position, you get into the in Figure 3 The illustrated rotary position of the transmission gear 9. Here, the crank pin 20 is at one end of the third, parallel to the direction of movement the drive rod 7 arranged section 30. During the drive from the closed position into the rotary position, the toggle lever 17 is first stretched until it has reached the end of the first inclined section 28 and is then angled again when moving over the second inclined section 29. Thus, when driving the section of the drive rod 7 via the handle 6, the translation and thus the force profile varies. This fact becomes in the description too Figure 5 and Figure 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.If you start from the in Figure 3 rotary position shown the handle 6 in the position "K", the transmission gear 9 is driven into the tilt position, which in Figure 4 is shown. Between the rotational position and the tilted position, the crank pin 20 is moved in parallel to the direction of movement of the section of the drive rod 7. During this movement, the toggle lever 17 is not stretched or angled, so that the transmission gear 9 has a constant translation 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. Figure 5 shows the course of the translation I of the transmission gear 9 when the handle is driven from the "Z" position through the "D" position into the "K" position. Between the “K” position and the “D” position, the transmission gear 9 has a constant ratio. If, starting from position “D”, the transmission gear 9 is moved in the direction of the locking position “Z”, a very high transmission ratio is first achieved, which means that initially with a slight rotation of the nut 11 there is a large displacement of the drive rod 7. Only when the crank pin 20 is in the first section 28 of the link 21 is the portion of the drive rod 7 driven with a low gear ratio. This means that a large rotation of the nut 11 only leads to a small displacement of the section 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". Figure 6 shows the course of the longitudinal movement x of the section of the drive rod 7 when the nut 11 is rotated through 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 gear ratio in front of the "Z" position leads to the fact that the frictional forces of the in Figure 1 closures 8 shown can be easily overcome. Outside the closed position, the closures 8 do not oppose any frictional forces to the drive of the drive rod 7, so that in these positions the drive can take place with a high gear ratio.
