Description

Die Erfindung betrifft einen Treibstangenbeschlag für einen gegen einen Rahmen schwenkbaren Flügel eines Fensters, einer Fenstertür oder dergleichen, mit einem Antriebsgetriebe zum Antrieb einer längsverschieblich geführten Treibstange in beide Bewegungsrichtungen, mit einer Koppeleinrichtung zwischen Antriebsgetriebe und Treibstange und mit einer Rückdrücksperre zur Blockierung oder Freigabe der Bewegung der Treibstange in Abhängigkeit von der Krafteinleitung und mit einem einer feststehenden Tasche gegenüberstehenden Sperrkörper zur teilweisen Aufnahme des Sperrkörpers bei einer treibstangenseitigen Krafteinleitung.The invention relates to a connecting rod fitting for a sash of a window, a balcony door or the like that can be pivoted against a frame, with a drive gear for driving a longitudinally displaceable drive rod in both directions of movement, with a coupling device between the drive gear and the drive rod and with a backstop to block or release the movement the drive rod as a function of the introduction of force and with a locking body facing a stationary pocket to partially accommodate the locking body when force is introduced on the drive rod side.

Ein solcher Treibstangenbeschlag ist beispielsweise aus der DE 35 20 861 A1 bekannt. Bei diesem Treibstangenbeschlag ist ein federndes Rückdrück-Sperrglied auf der Treibstange befestigt und gleitet über ein feststehendes, die Tasche aufweisendes Bauteil. Versucht man den Treibstangenbeschlag zu entriegeln, indem man zur Verschiebung der Treibstange eine Kraft in die Treibstange einleitet, gelangt das Sperrglied in die Tasche und blockiert dessen weitere Bewegung. Bei einer Krafteinleitung in den Treibstangenbeschlag über das Antriebsgetriebe wird das federnde Rückdrück-Sperrglied angehoben und über die Tasche hinweg bewegt. Damit wird bei einer treibstangenseitigen Krafteinleitung die Bewegung des Treibstangenbeschlages gesperrt, während der Treibstangenbeschlag bei einer getriebeseitigen Krafteinleitung betätigt werden kann. Nachteilig bei diesem Treibstangenbeschlag ist jedoch, dass das federnde Sperrglied zum Federn und zum Sperren eine Doppelfunktion aufweist, so dass es sehr aufwändig zu fertigen und zu montieren ist. Zudem werden für beide Bewegungsrichtungen zwei Rückdrücksperren benötigt. Hierdurch gestaltet sich der Treibstangenbeschlag baulich sehr aufwändig.Such an espagnolette is for example from the DE 35 20 861 A1 known. In this drive rod fitting, a resilient push-back locking member is attached to the drive rod and slides over a stationary component that has the pocket. If you try to unlock the drive rod fitting by introducing a force into the drive rod to move the drive rod, the locking member gets into the pocket and blocks its further movement. When a force is introduced into the drive rod fitting via the drive gear, the resilient push-back locking member is raised and moved over the pocket. In this way, when a force is introduced on the drive rod side, the movement of the drive rod fitting is blocked, while the drive rod fitting can be operated when a force is introduced on the gear unit. The disadvantage of this espagnolette fitting, however, is that the resilient locking member has a double function for springing and locking, so that it is very complex to manufacture and assemble. In addition, two backstops are required for both directions of movement. As a result, the connecting rod fitting is structurally very complex.

Weiterhin ist aus der EP 2 918 755 A1 ein Getriebe für eine Beschlaganordnung bekannt geworden, bei dem ein Sicherungselement an einem Nusselement zum Antrieb der Treibstange angeordnet ist. Das Sicherungselement wird bei einer von dem Nusselement ausgehenden Verstellbewegung in eine Freigabestellung und bei einer von dem Beschlagelement ausgehenden Verstellbewegung in die Sperrstellung gedrängt. Das Sicherungselement hat durch die Anordnung im Getriebe nur sehr kleine Abmessungen.Furthermore, from the EP 2 918 755 A1 a gear for a fitting arrangement has become known in which a securing element is arranged on a nut element for driving the drive rod. The securing element is in an adjustment movement originating from the nut element in a release position and in one of the Fitting element outgoing adjustment movement pushed into the locked position. The securing element has only very small dimensions due to the arrangement in the gearbox.

Der Erfindung liegt das Problem zugrunde, einen Treibstangenbeschlag der eingangs genannten Art so weiter zu bilden, dass er besonders einfach aufgebaut ist und dass die Rückdrücksperre hohe Kräfte abstützen kann.The invention is based on the problem of developing a connecting rod fitting of the type mentioned at the beginning in such a way that it has a particularly simple structure and that the back pressure lock can support high forces.

Dieses Problem wird erfindungsgemäß dadurch gelöst, dass die Treibstange für jede ihrer Bewegungsrichtungen jeweils eine, den Sperrkörper in Richtung der Tasche abstützende Stützkante hat.According to the invention, this problem is solved in that the drive rod has, for each of its directions of movement, a support edge which supports the locking body in the direction of the pocket.

Durch diese Gestaltung benötigt der Treibstangenbeschlag nur einen einzigen Sperrkörper zum Blockieren oder Freigeben der Treibstange in beide Richtungen. Dank der Erfindung wird der bauliche Aufwand hierdurch sehr gering gehalten. Der Treibstangenbeschlag ist hierdurch besonders einfach aufgebaut. Der Sperrkörper und die Stützkanten lassen sich außerhalb des Antriebsgetriebes sehr stabil und mit großen Abmessungen gestalten, so dass die Rückdrücksperre hohe Kräfte abzustützen vermag.As a result of this design, the connecting rod fitting only requires a single locking body to block or release the connecting rod in both directions. Thanks to the invention, the structural effort is kept very low as a result. The connecting rod fitting is particularly simple as a result. The blocking body and the supporting edges can be made very stable and with large dimensions outside of the drive gear, so that the back pressure lock is able to support high forces.

Ein zuverlässiger Kraftfluss bei einer Krafteinleitung durch das Antriebsgetriebe lässt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung einfach sicherstellen, wenn ein Kopplungsteil bei einer getriebeseitigen Krafteinleitung zur Erzeugung eines Kraftflusses von dem Antriebsgetriebe in die Treibstange ausgebildet ist.According to another advantageous development of the invention, a reliable power flow when force is introduced through the drive gear can be easily ensured if a coupling part is designed to generate a power flow from the drive gear into the drive rod when force is introduced on the transmission side.

Eine Blockade des Treibstangenbeschlages lässt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung zuverlässig vermeiden, wenn das Kopplungsteil in der Treibstange ein Spiel aufweist, so dass das Kopplungsteil mit dem Sperrkörper ohne Krafteinleitung in die Treibstange bewegbar ist. Damit wird sichergestellt, dass bei der getriebeseitigen Krafteinleitung das Koppelteil angetrieben wird und nach einer Überwindung des Spiels die Treibstange antreibt.According to another advantageous development of the invention, a blockage of the drive rod fitting can be reliably avoided if the coupling part has play in the drive rod so that the coupling part can be moved with the locking body without introducing force into the drive rod. This ensures that the coupling part is driven when the force is introduced on the transmission side and drives the drive rod after overcoming the play.

Eine Umgehung der Rückdrücksperre lässt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung einfach vermeiden, wenn die Rückdrücksperre an einer Koppeleinrichtung eines Anschlussschiebers des Antriebsgetriebes mit der Treibstange angeordnet ist. Durch diese Gestaltung ist die Rückdrücksperre zwischen dem Antriebsgetriebe und sämtlichen Verschlüssen des Treibstangenbeschlages angeordnet.Bypassing the back pressure lock can be easily avoided according to another advantageous development of the invention if the back pressure lock is arranged on a coupling device of a connecting slide of the drive gear with the drive rod. As a result of this design, the back pressure lock is arranged between the drive gear and all locks of the drive rod fitting.

Bei getriebeseitiger Krafteinleitung lässt sich eine Bewegung des Sperrkörpers in Richtung der feststehenden Tasche zuverlässig vermeiden, wenn das Kopplungsteil eine den Sperrkörper aufnehmende, quer zur Bewegungsrichtung der Treibstange angeordnete Führung hat. Durch diese Gestaltung wird der Sperrkörper von dem Kopplungsteil bei der getriebeseitigen Krafteinleitung einfach mit der Treibstange mitbewegt.When force is introduced on the transmission side, a movement of the locking body in the direction of the stationary pocket can be reliably avoided if the coupling part has a guide which receives the locking body and is arranged transversely to the direction of movement of the drive rod. As a result of this design, the locking body is simply moved along with the drive rod by the coupling part when the force is introduced on the transmission side.

Eine Blockade des Treibstangenbeschlages bei einem Hineinragen des Sperrkörpers in die Tasche ohne treibstangenseitige Krafteinleitung lässt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung einfach vermeiden, wenn die Tasche und der Sperrkörper an ihren gegenüberstehenden Abschnitten einander entsprechende Radien oder Rampen aufweisen. Durch diese Gestaltung wird der Sperrkörper bei der Bewegung der Treibstange über das Antriebsgetriebe einfach aus der Tasche herausgedrückt. Erst wenn über die Stützkanten der Treibstange eine in Richtung der Tasche weisende Kraftkomponente in den Sperrkörper geleitet wird, wird der Treibstangenbeschlag blockiert.A blockage of the drive rod fitting when the locking body protrudes into the pocket without force introduction on the drive rod side can be easily avoided according to another advantageous development of the invention if the pocket and the locking body have corresponding radii or ramps at their opposing sections. As a result of this design, the locking body is simply pushed out of the pocket when the drive rod is moved via the drive gear. Only when a force component pointing in the direction of the pocket is passed into the locking body via the support edges of the drive rod is the drive rod fitting blocked.

Die vorgesehene Kraftrichtung auf den Sperrkörper bei der treibstangenseitigen Krafteinleitung lässt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung einfach sicherstellen, wenn der Sperrkörper den Stützkanten gegenüberstehende Radien oder Rampen hat.According to another advantageous development of the invention, the intended direction of force on the locking body when the force is introduced on the drive rod side can be easily ensured if the locking body has radii or ramps opposite the support edges.

Eine zuverlässige Bewegung des von dem Kopplungsteil geführten Sperrkörpers über die Tasche hinweg lässt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung einfach sicherstellen, wenn das Kopplungsteil formschlüssig an dem Anschlussschieber des Antriebsgetriebes angeordnet ist.A reliable movement of the blocking body guided by the coupling part over the pocket can easily be ensured according to another advantageous development of the invention if the coupling part is arranged in a form-fitting manner on the connecting slide of the drive gear.

Zur weiteren konstruktiven Vereinfachung des Treibstangenbeschlages trägt es gemäß einer anderen vorteilhaften Weiterbildung der Erfindung bei, wenn der Sperrkörper als Kugel oder Zylinder ausgebildet ist, mittig in dem Kopplungsteil geführt ist und wenn die Treibstange zwischen den Stützkanten eine Aussparung zur Aufnahme des vollständig aus der Tasche entfernten Sperrkörpers hat.To further simplify the design of the espagnolette fitting, it contributes according to another advantageous development of the invention if the locking body is designed as a ball or cylinder, is guided centrally in the coupling part and if the driving rod has a recess between the support edges to accommodate the completely removed from the pocket Has locking body.

Die Rückdrücksperre gestaltet sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung konstruktiv besonders einfach, wenn der Sperrkörper von einem Federelement in Richtung der Tasche vorgespannt ist.According to another advantageous development of the invention, the back pressure lock is particularly simple in construction when the locking body is pretensioned by a spring element in the direction of the pocket.

Zur weiteren konstruktiven Vereinfachung der Rückdrücksperre trägt es gemäß einer anderen vorteilhaften Weiterbildung der Erfindung bei, wenn das Federelement als eine mit den Enden in dem Treibstangenabschnitt gehaltene Bügelfeder ausgebildet ist und mit einem mittleren Bereich in die Aussparung des Kopplungsteils hineinragt und den Sperrkörper übergreift.According to another advantageous development of the invention, the spring element is designed as a bow spring held with the ends in the drive rod section and protrudes with a central area into the recess of the coupling part and overlaps the locking body.

Figur 1 zeigt ein Fenster mit einem gegen einen Rahmen 1 schwenkbaren Flügel 2 und mit einem Treibstangenbeschlag 3 zur Verriegelung des Rahmens 1 in dem Flügel 2. Der Treibstangenbeschlag 3 hat eine von einem Antriebsgetriebe 4 längsverschiebliche Treibstange 5 zur Ansteuerung mehrerer Verschlüsse 6. Zwischen dem Antriebsgetriebe 4 und der Treibstange 5 ist eine Rückdrücksperre 7 angeordnet. Die Rückdrücksperre 7 ermöglicht einen Antrieb der Treibstange 5 über das Antriebsgetriebe 4 und sperrt die Bewegung der Treibstange 5 bei einem versuchten manuellen Antrieb der Treibstange 5 von der Seite der Verschlüsse 6 aus. Die Rückdrücksperre 7 ist in dem Ausführungsbeispiel nur an einer Seite oberhalb des Antriebsgetriebes 4 angeordnet. Bei diesem Ausführungsbeispiel kann beispielsweise um eine durchgehende, das Antriebsgetriebe 4 überbrückende Treibstange 5 eingesetzt sein. In einer alternativen Ausführungsform kann eine weitere, nicht dargestellte Rückdrücksperre 7 unterhalb des Antriebsgetriebes 4 angeordnet sein. Figure 1 shows a window with a sash 2 pivotable against a frame 1 and with a connecting rod fitting 3 for locking the frame 1 in the sash 2. The connecting rod fitting 3 has a drive rod 5 which is longitudinally displaceable by a drive gear 4 for controlling several locks 6 the drive rod 5 is a back pressure lock 7 is arranged. The return lock 7 enables the drive rod 5 to be driven via the drive gear 4 and blocks the movement of the drive rod 5 in the event of an attempted manual drive of the drive rod 5 from the side of the locks 6. In the exemplary embodiment, the backstop 7 is arranged on only one side above the drive gear 4. In this exemplary embodiment, for example, a continuous drive rod 5 bridging the drive gear 4 can be used. In an alternative embodiment, a further non-illustrated back pressure lock 7 can be arranged below the drive gear 4.

Figur 2 zeigt stark vergrößert die Rückdrücksperre 7 des Treibstangenbeschlages 3 aus Figur 1. Die Rückdrücksperre 7 ist in einer Koppeleinrichtung 8 zur Koppelung eines Anschlussschiebers 9 des Antriebsgetriebes 4 mit der Treibstange 5 angeordnet und hat ein Kopplungsteil 10 und einen Sperrkörper 11. Ein Gehäuse 12 zur Führung der miteinander gekoppelten Enden des Anschlussschiebers 9 und der Treibstange 5 ist feststehend im Flügel 2 aus Figur 1 montiert und hat eine Tasche 13, in die der Sperrkörper 11 von der Kraft eines Federelementes 14 vorgespannt ist. Die Tasche 13 und der Sperrkörper 11 weisen einander entsprechende Radien 15, 16 auf. Der Sperrkörper 11 ist zylindrisch gestaltet und hat eine quer zur Bewegungsrichtung der Treibstange 5 angeordnete Führung 17 in dem Kopplungsteil 10. Diese Führung 17 führt einen mittleren Bereich des Sperrkörpers 11. In der Treibstange 5 ist eine der Führung 17 gegenüberstehende Aussparung 18 angeordnet. Die Aussparung 18 wird begrenzt von dem Sperrkörper 11 an jeder Seite gegenüberstehenden Stützkanten 19, 20. Das Kopplungsteil 10 ist nahezu spielfrei in dem Anschlussschieber 9 angeordnet. In einer nicht dargestellten Ausführungsform kann das Kopplungsteil 10 auch als Abwinklung des Anschlussschiebers 9 gestaltet sein. Weiterhin zeigt Figur 2, dass das Kopplungsteil 10 ein Spiel S in der Treibstange 5 hat. Damit lässt sich die Treibstange 5 geringfügig verschieben, bis die Stützkanten 19, 20 gegen den Sperrkörper 11 gelangen und ein Herausdrücken aus der Führung 17 des Kopplungselementes 10 verhindern. Figure 2 shows the back pressure lock 7 of the drive rod fitting 3 from a greatly enlarged Figure 1 . The back pressure lock 7 is arranged in a coupling device 8 for coupling a connecting slide 9 of the drive gear 4 to the drive rod 5 and has a coupling part 10 and a locking body 11. A housing 12 for guiding the ends of the connection slide 9 and the drive rod 5 which are coupled to one another is stationary in the Wing 2 off Figure 1 mounted and has a pocket 13 into which the locking body 11 is biased by the force of a spring element 14. The pocket 13 and the locking body 11 have radii 15, 16 that correspond to one another. The locking body 11 is cylindrical and has a guide 17 arranged transversely to the direction of movement of the drive rod 5 in the coupling part 10. This guide 17 guides a central region of the locking body 11. In the drive rod 5, a recess 18 opposite the guide 17 is arranged. The recess 18 is delimited by the blocking body 11 on each side opposite supporting edges 19, 20. The coupling part 10 is arranged in the connecting slide 9 with almost no play. In an embodiment not shown, the coupling part 10 can also be designed as an angled portion of the connecting slide 9. Furthermore shows Figure 2 that the coupling part 10 has a play S in the connecting rod 5. The drive rod 5 can thus be moved slightly until the support edges 19, 20 come against the locking body 11 and prevent it from being pushed out of the guide 17 of the coupling element 10.

Zur Vereinfachung der Zeichnung ist in Figur 2 das Gehäuse 12 aufgeschnitten dargestellt, um die Bauteile der Rückdrücksperre 7 von der Seite der Treibstange 5 aus darzustellen. Das mit dem Koppelteil 10 verbundene Ende des Anschlussschiebers 9 ist in Figur 2 hinter dem dargestellten Abschnitt der Treibstange angeordnet.To simplify the drawing, in Figure 2 the housing 12 is shown cut open in order to show the components of the back pressure lock 7 from the side of the drive rod 5. The end of the connecting slide 9 connected to the coupling part 10 is shown in FIG Figure 2 arranged behind the illustrated section of the drive rod.

Figur 3 zeigt die Bauteile der Rückdrücksperre 7 in einer perspektivischen Explosionsdarstellung. Im Gegensatz zu der Darstellung aus Figur 2 zeigt Figur 3 die Bauteile der Rückdrücksperre 7 geringfügig verkleinert von der Seite des Anschlussschiebers 9. Das Federelement 14 ist bügelförmig gestaltet und übergreift in der montierten Stellung den Sperrkörper 11. Der Sperrkörper 11 ist zylindrisch gestaltet. Das Koppelteil 10 hat eine Höhe, welche der gemeinsamen Materialstärke von Anschlussschieber 9 und Treibstange 5 entspricht. Figure 3 shows the components of the back pressure lock 7 in a perspective exploded view. In contrast to the representation from Figure 2 shows Figure 3 the components of the backpressure lock 7 slightly reduced in size from the side of the connecting slide 9. The spring element 14 is bow-shaped and, in the assembled position, engages over the locking body 11. The locking body 11 is cylindrical. The coupling part 10 has a height which corresponds to the common material thickness of the connecting slide 9 and the drive rod 5.

Wenn man ausgehend von Figur 2 getriebeseitig und damit von dem Anschlussschieber 9 aus eine Kraft in die Rückdrücksperre 7 einleitet, gelangt man in die in Figur 4 dargestellte Stellung. Die in dieser Figur mit einem Pfeil gekennzeichnete Kraft wird von dem Anschlussschieber 9 in das Kopplungsteil 10 eingeleitet. Das Kopplungsteil 10 führt den Sperrkörper 11 und gelangt nach Überwindung des in Figur 2 dargestellten Spiels S gegen die Treibstange 5. Da abgesehen von der Kraft des Federelementes 14, keine Kräfte quer zur Bewegungsrichtung der Treibstange 5 in den Sperrkörper 11 eingeleitet werden, kann dieser von den Radien 15, 16 aus der Tasche 13 herausgedrückt werden. Anschließend werden Kopplungsteil 10 und Sperrkörper 11 mit dem Anschlussschieber 9 und der Treibstange 5 verschoben.If you start from Figure 2 on the transmission side and thus introduces a force into the backpressure lock 7 from the connecting slide 9, one arrives at the in Figure 4 shown Position. The force marked with an arrow in this figure is introduced into the coupling part 10 by the connecting slide 9. The coupling part 10 guides the locking body 11 and, after overcoming the in Figure 2 Play S shown against the drive rod 5. Since, apart from the force of the spring element 14, no forces are introduced into the locking body 11 transversely to the direction of movement of the drive rod 5, this can be pushed out of the pocket 13 by the radii 15, 16. Then the coupling part 10 and the locking body 11 with the connecting slide 9 and the drive rod 5 are moved.

Wenn man ausgehend von Figur 2 treibstangenseitig eine Kraft in die Rückdrücksperre 7 einleitet, gelangt man in die in Figur 5 dargestellte Stellung. In dieser Figur ist die in die Treibstange 5 eingeleitete Kraft mit einem Pfeil gekennzeichnet. Die Bewegung der Treibstange 5 bei feststehendem Anschlussschieber 9 führt dazu, dass eine der Stützkanten 19 gegen den Sperrkörper 11 gelangt und diesen in die Tasche 13 drückt. Damit blockiert der Sperrkörper 11 die weitere Bewegung der Treibstange 5. Der Anschlussschieber 9 wird damit ebenfalls nicht mitbewegt.If you start from Figure 2 introduces a force into the back pressure lock 7 on the drive rod side, one arrives at the in Figure 5 position shown. In this figure, the force introduced into the drive rod 5 is marked with an arrow. The movement of the drive rod 5 when the connecting slide 9 is stationary has the result that one of the support edges 19 comes against the locking body 11 and presses it into the pocket 13. The blocking body 11 thus blocks the further movement of the drive rod 5. The connecting slide 9 is thus also not moved with it.
