Definitions

  • the invention relates to a corner deflection for a connecting rod fitting of a wing of a window, a French window or the like pivotable against a frame with a deflection element, with a curved section and with straight sections adjoining the curved section of the deflection element, the deflection element being arranged in a guide housing and the guide housing holds the deflection element on the bent section and the deflection element has at least one flexible spring band and a spring housing for guiding the at least one spring band.

Description

Die Erfindung betrifft eine Eckumlenkung für einen Treibstangenbeschlag eines gegen einen Rahmen schwenkbaren Flügels eines Fensters, einer Fenstertür oder dergleichen mit einem Umlenkelement, mit einem gebogenen Abschnitt und mit sich an den gebogenen Abschnitt anschließenden geraden Abschnitten des Umlenkelementes, wobei das Umlenkelement in einem Führungsgehäuse angeordnet ist und das Führungsgehäuse das Umlenkelement an dem gebogenen Abschnitt hält und das Umlenkelement zumindest ein biegsames Federband und ein Federgehäuse zur Führung des zumindest einen Federbandes hat.The invention relates to a corner deflection for a connecting rod fitting of a wing of a window, a French window or the like pivotable against a frame with a deflection element, with a curved section and with straight sections adjoining the curved section of the deflection element, the deflection element being arranged in a guide housing and the guide housing holds the deflection element on the bent section and the deflection element has at least one flexible spring band and a spring housing for guiding the at least one spring band.

Aus der FR 2 275 626 A1 ist eine Eckumlenkung bekannt geworden, bei der innerhalb eines Führungsgehäuses Kupplungen zur Verbindung des Federbandes mit steifen Treibstangenabschnitten angeordnet sind. Damit benötigt das Führungsgehäuse ebenfalls sehr lange gerade Abschnitte zur Führung der steifen Treibstangenabschnitte. Die Eckumlenkung hat hierdurch besonders große Abmessungen.From the FR 2 275 626 A1 a corner deflection has become known in which couplings for connecting the spring band with rigid drive rod sections are arranged within a guide housing. The guide housing therefore also requires very long straight sections for guiding the rigid connecting rod sections. As a result, the corner drive has particularly large dimensions.

Aus der DE 26 01 390 A1 ist eine Eckumlenkung für Treibstangenbeschläge bekannt, bei dem ein Führungsgehäuse sehr lang gestreckte gerade Abschnitte aufweist. An den geraden Abschnitten sind steife Treibstangenabschnitte geführt. Die Eckumlenkung hat hierdurch besonders große Abmessungen.From the DE 26 01 390 A1 a corner drive for espagnolette fittings is known in which a guide housing has very elongated straight sections. Rigid drive rod sections are guided on the straight sections. As a result, the corner drive has particularly large dimensions.

Aus der DE 199 57 359 A1 ist eine Eckumlenkung bekannt geworden, bei der ein Eckformstück sich im Wesentlichen nur über den gebogenen Bereich eines Federbandes erstreckt. Das Eckformstück weist zudem eine Führung für das Federband auf. Bei der Montage eines Treibstangenbeschlages ist es jedoch wünschenswert die einzelnen Bauteile in einer Montagestellung zu fixieren.From the DE 199 57 359 A1 a corner deflection has become known, in which a corner fitting extends essentially only over the bent region of a spring band. The corner fitting also has a guide for the spring band. When installing an espagnolette fitting, however, it is desirable to fix the individual components in an assembly position.

Aus der EP 1 022 418 A1 ist eine Eckumlenkung bekannt geworden, bei der ein Führungskanal zur Führung von Umlenkgliedern eine Ausgleichseinrichtung hat. Die Ausgleichseinrichtung verlagert einen Abschnitt des Führungskanals, so dass Toleranzen ausgeglichen werden können.From the EP 1 022 418 A1 a corner deflection has become known in which a guide channel for guiding deflection members has a compensating device. The compensation device shifts a section of the guide channel so that tolerances can be compensated.

Eine Eckumlenkung ist beispielsweise aus der EP 2 199 505 A2 bekannt. Bei dieser Eckumlenkung erstreckt sich eine Führung für das Umlenkelement über zwei Schenkel. Das Umlenkelement hat Koppelelemente mit Formschlussflächen zur Verbindung mit angrenzenden Treibstangenabschnitten. Das Umlenkelement weist einen schwenkbaren Arm auf, welcher von einem Schieber derart verschwenkt werden kann, dass die Formschlussflächen des Umlenkelementes in Formschlussflächen des angrenzenden Treibstangenabschnitts gedrückt werden. Hierdurch ist eine teilweise verdeckte Anordnung des Ecklagers in dem Flügel möglich. Nachteilig bei diesem Ecklager ist jedoch, dass es eine große Tasche im Flügel erfordert.A corner drive is, for example, from the EP 2 199 505 A2 known. In this corner deflection, a guide for the deflecting element extends over two legs. The deflecting element has coupling elements with positive locking surfaces for connection to adjacent drive rod sections. The deflecting element has a pivotable arm, which can be pivoted by a slide such that the form-fitting surfaces of the deflecting element are pressed into the form-fitting surfaces of the adjacent drive rod section. This enables a partially concealed arrangement of the corner bearing in the wing. A disadvantage of this corner bearing, however, is that it requires a large pocket in the wing.

Aus der EP 2 142 737 B1 ist eine Eckumlenkung mit zwei Schenkeln bekannt geworden. Die Schenkel weisen jeweils eine Linearführung mit einem in der Linearführung geführten Schlitten auf. Die Schlitten sind über ein Umlenkmittel miteinander gekoppelt. Nachteilig bei der Eckumlenkung ist, dass es für die beiden Schenkel eine sehr große Tasche im Flügel benötigt, welche von außen zugänglich sein muss.From the EP 2 142 737 B1 a corner drive with two legs has become known. The legs each have a linear guide with a slide guided in the linear guide. The slides are coupled to one another via a deflection means. A disadvantage of the corner deflection is that it requires a very large pocket in the wing for the two legs, which must be accessible from the outside.

Der Erfindung liegt das Problem zugrunde, eine Eckumlenkung der eingangs genannten Art so weiter zu bilden, dass sie möglichst kleine Abmessungen aufweist und einfach aufgebaut ist.The invention is based on the problem of further developing a corner deflection of the type mentioned at the outset in such a way that it has the smallest possible dimensions and is simple in construction.

Dieses Problem wird erfindungsgemäß dadurch gelöst, dass das Federband von einem Fixierelement mit einem vorgesehenen Kraftaufwand in einer vorgesehenen Montagelage gehalten ist so dass die Halterung des Federbandes bei der Erstbetätigung des Treibstangenbeschlages lösbar ist und dass das Fixierelement eine Führung in dem Führungsgehäuse hat.This problem is solved according to the invention in that the spring band is held by a fixing element with an intended expenditure of force in a provided mounting position, so that the spring band can be released when the connecting rod fitting is actuated for the first time and that the fixing element has a guide in the guide housing.

Durch diese Gestaltung lässt sich das Führungsgehäuse besonders klein gestalten. Daher kann die erfindungsgemäße Eckumlenkung auch in einer möglichst klein bemessenen Tasche im Flügel angeordnet werden. Da das Führungsgehäuse die Eckumlenkung an dem gebogenen Abschnitt hält, können die geraden Abschnitte des Umlenkelementes einfach aus dem Führungsgehäuse herausragen. Die Enden der geraden Abschnitte werden vorzugsweise von angrenzenden Funktionselementen des Treibstangenbeschlages geführt. Die Eckumlenkung gestaltet sich konstruktiv besonders einfach, weil das Umlenkelement zumindest ein biegsames Federband und ein Federgehäuse zur Führung des zumindest einen Federbandes hat. Eine so genannte Mittenfixierung der Eckumlenkung lässt sich einfach erzeugen, weil das Federband von einem Fixierelement mit einem vorgesehenen Kraftaufwand in einer vorgesehenen Montagelage gehalten ist. Durch diese Gestaltung ist die von dem Fixierelement auf das Federband ausgeübte Haltekraft begrenzt, so dass die Halterung des Federbandes bei der Erstbetätigung des Treibstangenbeschlages lösbar ist. Die Eckumlenkung gestaltet sich besonders kompakt, weil das Fixierelement eine Führung in dem Führungsgehäuse hat. Da sich das Führungsgehäuse im Wesentlichen über den gebogenen Abschnitt des Umlenkelementes erstreckt, ist an dieser Stelle eine besonders große Materialstärke für die Erzeugung der Führung für das Fixierelement vorhanden.This design allows the guide housing to be made particularly small. Therefore, the corner deflection according to the invention can also be arranged in the smallest possible pocket in the wing. Since the guide housing holds the corner deflection on the curved section, the straight sections of the deflection element can simply protrude from the guide housing. The ends of the straight sections are preferably guided by adjacent functional elements of the connecting rod fitting. The corner deflection is structurally particularly simple because the deflecting element has at least one flexible spring band and a spring housing for guiding the at least one spring band. A so-called center fixation of the corner deflection can be produced simply because the spring band is held in a planned mounting position by a fixing element with a planned effort. This design limits the holding force exerted by the fixing element on the spring band, so that the holder the spring band is detachable when the espagnolette fitting is actuated for the first time. The corner deflection is particularly compact because the fixing element has a guide in the guide housing. Since the guide housing extends essentially over the curved section of the deflecting element, a particularly large material thickness is available at this point for producing the guide for the fixing element.

Die Eckumlenkung weist gemäß einer anderen vorteilhaften Weiterbildung der Erfindung besonders kleine Abmessungen auf, wenn sich das Führungsgehäuse an zumindest einer Seite ausschließlich über den gebogenen Abschnitt des Umlenkelementes erstreckt. Damit ragt an dieser Seite der gerade Abschnitt des Umlenkelementes aus dem Führungsgehäuse heraus. Durch diese Gestaltung kann an dieser Seite unmittelbar angrenzend an den gebogenen Abschnitt ein weiteres Funktionselement, wie beispielsweise ein Verschluss angeordnet werden. Alternativ dazu kann eine Tasche im Flügel zur Aufnahme des Führungsgehäuses besonders klein gehalten werden.According to another advantageous development of the invention, the corner deflection has particularly small dimensions if the guide housing extends on at least one side exclusively over the curved section of the deflection element. The straight section of the deflecting element thus protrudes from the guide housing on this side. This design allows a further functional element, such as a closure, to be arranged on this side immediately adjacent to the curved section. Alternatively, a pocket in the wing for receiving the guide housing can be kept particularly small.

Die Eckumlenkung lässt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung besonders kostengünstig fertigen, wenn das Führungsgehäuse eine Nut zur Aufnahme eines Teilbereichs des Umlenkelementes hat.According to another advantageous development of the invention, the corner deflection can be manufactured particularly cost-effectively if the guide housing has a groove for receiving a partial area of the deflection element.

Die Montage der Eckumlenkung gestaltet sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung besonders einfach, wenn die Nut quer zu ihrer längsten Erstreckung zu einer Seite des Führungsgehäuses hin offen ist. Weiterhin lässt sich das Umlenkelement durch diese Gestaltung einfach quer zu seiner längsten Erstreckung in die Nut eindrücken und gegebenenfalls verrasten. Damit gestaltet sich zudem die Montage der Eckumlenkung besonders einfach.According to another advantageous development of the invention, the corner deflection is particularly easy to install if the groove is open transversely to its longest extension to one side of the guide housing. Furthermore, the deflection element can be simply pressed into the groove transversely to its longest extent and, if necessary, locked in place. This also makes the installation of the corner drive particularly easy.

Die Eckumlenkung ermöglicht gemäß einer anderen vorteilhaften Weiterbildung der Erfindung einen Ausgleich von Winkelabweichungen der geraden Abschnitte, wenn die Nut an zumindest einer Begrenzung des Führungsgehäuses Erweiterungen aufweist.According to another advantageous development of the invention, the corner deflection enables compensation of angular deviations of the straight sections if the groove has extensions on at least one boundary of the guide housing.

Die Eckumlenkung ist besonders leicht und stabil ausgeführt, wenn das Führungsgehäuse einstückig ausgeführt ist und aus einer Grundplatte und darauf senkrecht aufgesetzten Begrenzung- und Verstärkungsrippen besteht. Die Begrenzung- und Verstärkungsrippen sind dabei idealerweise zumindest teilweise miteinander verbunden, um eine hohe Gesamtsteifigkeit zu erreichen. Bei dieser Ausführungsform haben die aufgesetzten Begrenzung- und Verstärkungsrippen jeweils ein der Grundplatte abgewandtes freies Ende, so dass sichtbare Kammern entstehen. Auch die offene Nut zur Aufnahme eines Teilbereichs des Umlenkelementes ist hierdurch gut realisierbar.The corner deflection is particularly light and stable when the guide housing is made in one piece and consists of a base plate and limiting and reinforcing ribs placed vertically thereon. The limiting and reinforcing ribs are ideally at least partially connected to one another in order to achieve a high overall rigidity. In this embodiment, the limit and Reinforcing ribs each have a free end facing away from the base plate, so that visible chambers are created. The open groove for receiving a partial area of the deflecting element can also be easily realized in this way.

Das Führungsgehäuse kann somit einfach einstückig, z.B. aus Kunststoff hergestellt werden. Dieser Aufbau des Führungsgehäuses ist möglich, da die der Grundplatte gegenüberliegende Seite nach der Montage der Eckumlenkung in den Flügel zumindest weitgehend unsichtbar ist und daher keine besonderen Anforderungen an die optische Ausgestaltung stellt.The guide housing can thus simply be in one piece, e.g. be made of plastic. This construction of the guide housing is possible since the side opposite the base plate is at least largely invisible after the corner deflection has been installed in the wing and therefore does not make any particular demands on the optical design.

Die Eckumlenkung ermöglicht gemäß einer anderen vorteilhaften Weiterbildung der Erfindung eine sehr nahe Anordnung von Funktionselementen in Eckbereichen des Flügels, wenn zumindest einer der geraden Abschnitte in einem Funktionselement, insbesondere einem Funktionselement eines Verschlusses, des Treibstangenbeschlages angeordnet ist. Damit wird das Funktionselement Teil der Eckumlenkung.According to another advantageous development of the invention, the corner deflection enables a very close arrangement of functional elements in corner areas of the wing if at least one of the straight sections is arranged in a functional element, in particular a functional element of a lock, of the connecting rod fitting. The functional element thus becomes part of the corner drive.

Eine Zerstörung des Fixierelementes bei der Erstbetätigung des Treibstangenbeschlages lässt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung vermeiden, wenn das Fixierelement kraftschlüssig oder stoffschlüssig an dem Federband gehalten ist. Durch diese Gestaltung wird bei der Erstbetätigung des Treibstangenbeschlages der Kraftschluss oder der Stoffschluss mit dem Federband aufgehoben. Der Stoffschluss kann beispielsweise mittels Klebstoff erzeugt werden.A destruction of the fixing element when the espagnolette fitting is actuated for the first time can be avoided according to another advantageous development of the invention if the fixing element is held on the spring band in a force-fitting or material-locking manner. This design eliminates the frictional connection or the material connection with the spring band when the espagnolette fitting is operated for the first time. The material bond can be created, for example, using adhesive.

Die Kraft zur Lösung der Verbindung des Fixierelementes mit dem Federband lässt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung besonders genau begrenzen, wenn das Fixierelement einen in eine Ausnehmung des Federbandes eindringenden Vorsprung hat. Der Vorsprung kann beispielsweise Scherstift ausgebildet sein und bei dem vorgesehenen Kraftaufwand abscheren oder als Kegelstumpf ausgebildet sein und von dem vorgesehenen Kraftaufwand aus dem Bewegungsbereich des Federbandes heraus geschoben werden.According to another advantageous development of the invention, the force for releasing the connection of the fixing element to the spring band can be particularly precisely limited if the fixing element has a projection which penetrates into a recess in the spring band. The protrusion can be designed, for example, as a shear pin and shear off when the force required is provided or as a truncated cone and can be pushed out of the range of movement of the spring band by the force required.

The deflection element 11 has a spring housing 17 with a flexible spring band 18 arranged therein. The spring band 18 holds the coupling elements 15, 16. A fixing element 19 is arranged in the bent section 12 of the deflection element 11.

Das Führungsgehäuse 10 ist einstückig ausgeführt und besteht aus einer Grundplatte 34 und darauf senkrecht aufgesetzten Begrenzung- und Verstärkungsrippen 33. Es hat eine Nut 20 zur Aufnahme des gebogenen Abschnitts 12 des Umlenkelementes 11. Die Nut 20 weist an ihren den geraden Abschnitten 13, 14 zugewandten Enden Erweiterungen 21, 22 auf und ermöglicht einen Toleranzausgleich zu den angrenzenden Funktionselementen 6. Das Führungsgehäuse 10 ist aus Kunststoff, vorzugsweise im Spritzgussverfahren, gefertigt und erstreckt sich in dieser Ausführungsform ausschließlich über den gebogenen Abschnitt 12 des Umlenkelementes 11.The guide housing 10 is made in one piece and consists of a base plate 34 and limiting and reinforcing ribs 33 placed vertically thereon. It has a groove 20 for receiving the curved section 12 of the deflecting element 11. The groove 20 faces the straight sections 13, 14 Ends extensions 21, 22 and enables tolerance compensation to the adjacent functional elements 6. The guide housing 10 is made of plastic, preferably by injection molding, and in this embodiment extends exclusively over the curved section 12 of the deflecting element 11.

Figur 3 zeigt vergrößert eine der Eckumlenkungen 5 aus Figur 1 mit einem Führungsgehäuse 23 und einem Umlenkelement 24. Die Eckumlenkung 5 unterscheidet sich von der aus Figur 2 nur dadurch, dass das Führungsgehäuse 23 L-förmig gestaltet ist und sich über einen gebogenen Abschnitt 25 des Umlenkelementes 24 und über einen von zwei geraden Abschnitten 26, 27 erstreckt. Ansonsten ist die Eckumlenkung 5 wie die aus Figur 2 aufgebaut. Figure 3 shows one of the corner deflections 5 enlarged Figure 1 with a guide housing 23 and a deflection element 24. The corner deflection 5 differs from that Figure 2 only in that the guide housing 23 is L-shaped and extends over a curved section 25 of the deflection element 24 and over one of two straight sections 26, 27. Otherwise, the corner drive 5 is like that Figure 2 built up.

Figur 4 zeigt stark vergrößert eine Schnittdarstellung durch einen Teilbereich der Eckumlenkung 4 aus Figur 2 im Bereich des gebogenen Abschnitts 12 des Umlenkelements 11 mit dem Fixierelement 19. Hierbei ist zu erkennen, dass das Fixierelement 19 eine Führung 28 in dem Führungsgehäuse 10 hat. Das Federgehäuse 17 hat ebenfalls einen Kragen 29 zur Führung des Fixierelementes 19. Das Fixierelement 19 hat einen in eine Ausnehmung 30 des Federbandes 18 eindringenden kegelförmigen Vorsprung 31. Das Fixierelement 19 hält das Federband 18 während der Montage des Treibstangenbeschlages 3 in einer vorgesehenen Lage. Bei der Erstbetätigung des Treibstangenbeschlages 3 wird das Federband 18 verschoben und das Fixierelement 19 aus der Ausnehmung 30 im Federband 18 heraus gedrückt. Anschließend lässt sich das Federband 18 frei bewegen. Figure 4 shows a greatly enlarged sectional view through a partial area of the corner deflection 4 Figure 2 in the area of the curved section 12 of the deflection element 11 with the fixing element 19. It can be seen here that the fixing element 19 has a guide 28 in the guide housing 10. The spring housing 17 also has a collar 29 for guiding the fixing element 19. The fixing element 19 has a conical projection 31 penetrating into a recess 30 in the spring band 18. The fixing element 19 holds the spring band 18 during the assembly of the drive rod fitting 3 in an intended position. When the espagnolette fitting 3 is actuated for the first time, the spring band 18 is displaced and the fixing element 19 is pressed out of the recess 30 in the spring band 18. The spring band 18 can then be moved freely.

Figur 5 zeigt die Eckumlenkung 4 aus Figur 2 mit einer weiteren Ausführungsform des Fixierelementes 32. Das Fixierelement 32 ist kraftschlüssig oder stoffschlüssig an der Oberfläche des Federbandes 18 gehalten. Bei der Erstbetätigung des Treibstangenbeschlages 3 wird der Kraftschluss oder der Stoffschluss gelöst und das Federband 18 lässt sich anschließend frei bewegen. Figure 5 shows the corner drive 4 Figure 2 with a further embodiment of the fixing element 32. The fixing element 32 is held on the surface of the spring band 18 in a force-locking or material-locking manner. When the connecting rod fitting 3 is actuated for the first time, the frictional connection or the material connection is released and the spring band 18 can then be moved freely.
