Abstract

Eine Anordnung (4) zur Unterstützung einer Öffnungsbewegung eines Flügels (3) bezüglich eines festen Rahmens (2) eines Fensters (1) oder einer Tür, mit einer Federvorrichtung (5), die ein Federelement (7) aufweist, ist gekennzeichnet durch ein Spannelement (10), welches das Federelement (7) beim Entriegeln des Fensters (1) oder der Tür spannt.An arrangement (4) for assisting an opening movement of a wing (3) with respect to a fixed frame (2) of a window (1) or a door, with a spring device (5) having a spring element (7) is characterized by a tensioning element (10), which biases the spring element (7) when unlocking the window (1) or the door.

Description

Die Erfindung betrifft eine Anordnung zur Unterstützung einer Öffnungsbewegung eines Flügels bezüglich eines festen Rahmens eines Fensters oder einer Tür, mit einer Federvorrichtung, die ein Federelement aufweist. Weiterhin betrifft die Erfindung ein Fenster oder eine Tür mit einer erfindungsgemäßen Anordnung sowie ein Verfahren zum unterstützten Öffnen eines Flügels eines Fensters oder einer Tür.The invention relates to an arrangement for supporting an opening movement of a wing with respect to a fixed frame of a window or a door, with a spring device having a spring element. Furthermore, the invention relates to a window or a door with an inventive arrangement and a method for assisted opening of a wing of a window or a door.

Nach dem Entriegeln muss zum Öffnen eines schweren Flügels eines Fensters oder einer Tür häufig eine große Kraft aufgebracht werden. Insbesondere tritt dieses Problem bei Kipp-Schiebetüren mit einem Flügelgewicht über 160 kg auf. Auch bei Dreh-Kipp-Fenstern können so schwere Flügel eingesetzt werden, dass es notwendig ist, die Öffnungsbewegung zu unterstützen.After unlocking, a large force must often be applied to open a heavy wing of a window or door. In particular, this problem occurs in tilt-sliding doors with a sash weight over 160 kg. Even with tilt and turn windows so heavy wings can be used that it is necessary to support the opening movement.

Aus der DE 103 00 655 A1 ist beispielsweise ein Fenster oder eine Tür mit wenigstens einem Flügel bekannt, der verschwenkbar an einem Blendrahmen angeordnet ist, wobei eine Antriebsvorrichtung zum selbsttätigen Bewegen des Flügels relativ zum Blendrahmen vorgesehen ist. Die Antriebsvorrichtung weist einen Kraft- und Energiespeicher auf, weicher zum Abgeben seiner Energie beim Öffnen des Flügels ausgelegt ist. Bei der Anordnung der DE 103 00 655 A1 wird der Kraft- und Energiespeicher beim Schließen des Flügels gespannt. Dies bedeutet, dass der Kraft- und Energiespeicher stets gespannt ist, wenn das Fenster oder die Tür geschlossen ist. Dies kann zu einer Ermüdung des Kraft- und Energiespeichers führen.From the DE 103 00 655 A1 For example, a window or door with at least one wing is known, which is pivotable on a Blendrahmen is arranged, wherein a drive device is provided for automatically moving the wing relative to the frame. The drive device has a power and energy storage, which is designed to deliver its energy when opening the wing. In the arrangement of DE 103 00 655 A1 the power and energy storage is tensioned when closing the wing. This means that the power and energy storage is always tense when the window or door is closed. This can lead to fatigue of the power and energy storage.

Aufgabe der vorliegenden Erfindung ist es daher, diesbezüglich Abhilfe zu schaffen.Object of the present invention is therefore to remedy this situation.

Gelöst wird diese Aufgabe erfindungsgemäß durch eine Anordnung zur Unterstützung einer Öffnungsbewegung eines Flügels bezüglich eines festen Rahmens eines Fensters oder einer Tür, mit einer Federvorrichtung, die ein Federelement aufweist, wobei ein Spannelement vorgesehen ist, welches das Federelement beim Entriegeln des Fensters oder der Tür spannt. Dies bedeutet, dass das Federelement der Federvorrichtung erst unmittelbar vor dem Öffnen des Flügels des Fensters oder der Tür gespannt wird. Insbesondere kann das Federelement entspannt sein, wenn der Flügel des Fensters oder der Tür in einer Schließstellung beziehungsweise das Fenster oder die Tür verriegelt ist. Dadurch kann einer Ermüdung des Federelements vorgebeugt werden.This object is achieved according to the invention by an arrangement for supporting an opening movement of a wing with respect to a fixed frame of a window or door, with a spring device having a spring element, wherein a clamping element is provided which biases the spring element when unlocking the window or the door , This means that the spring element of the spring device is tensioned only immediately before the opening of the wing of the window or the door. In particular, the spring element can be relaxed when the wing of the window or the door is locked in a closed position or the window or the door. As a result, fatigue of the spring element can be prevented.

Besondere Vorteile ergeben sich, wenn das Spannelement mit einem zum Verriegeln und Entriegeln des Fensters oder der Tür dienenden Beschlag koppelbar ist. Vorzugsweise kann das Spannelement mit einem Treibstangenbeschlag koppelbar sein. Dabei kann das Spannelement besonders bevorzugt mit der Treibstange des Treibstangenbeschlags koppelbar sein. Wenn demnach der Beschlag zum Entriegeln des Fensters oder der Tür betätigt wird, wird das mit dem Beschlag gekoppelte Spannelement verlagert und dabei das Federelement der Federvorrichtung gespannt. Anschließend, beim Öffnen des Flügels, kann sich das Federelement nach wie vor am Spannelement abstützen und sich während der Öffnungsbewegung entspannen. Dadurch wird die Öffnungsbewegung unterstützt. Insbesondere werden Kraftspitzen beim Öffnen des Flügels abgefangen. Die erfindungsgemäße Anordnung ist dabei vorzugsweise so ausgelegt, dass der Flügel nicht von selbst aufgeht, nachdem der Flügel entriegelt wurde.Particular advantages arise when the clamping element can be coupled with a serving for locking and unlocking the window or the door fitting. Preferably, the clamping element can be coupled with a drive rod fitting. In this case, the tensioning element particularly preferably with the drive rod of the espagnolette fitting be coupled. Accordingly, when the fitting is actuated to unlock the window or the door, the clamping element coupled to the fitting is displaced, thereby tensioning the spring element of the spring device. Then, when opening the wing, the spring element can still be supported on the clamping element and relax during the opening movement. This supports the opening movement. In particular, force peaks are intercepted when opening the wing. The arrangement according to the invention is preferably designed so that the wing does not open by itself after the wing has been unlocked.

Das Spannelement kann beispielsweise als Zapfen ausgebildet sein, oder einen solchen aufweisen, welcher mit dem Beschlag des Fensters oder der Tür koppelbar ist.The clamping element may be formed, for example, as a pin, or have such, which is coupled to the fitting of the window or the door.

Weitere Vorteile ergeben sich, wenn das Spannelement beim Öffnen des Fensters oder der Tür von der Federvorrichtung entkoppelbar ist. Dadurch wird die Öffnungsbewegung des Flügels durch die erfindungsgemäße Anordnung nicht begrenzt. Außerdem wird durch diese Maßnahme ermöglicht, dass sich das Federelement nicht beim Schließen des Flügels automatisch spannt, da die Federvorrichtung und das Spannelement entkoppelt sind, wenn der Flügel geschlossen wird.Further advantages arise when the clamping element is decoupled when opening the window or the door of the spring device. As a result, the opening movement of the wing is not limited by the arrangement according to the invention. In addition, this measure makes it possible that the spring element does not automatically tension when closing the wing, since the spring device and the clamping element are decoupled when the wing is closed.

Die Federvorrichtung kann vorzugsweise schwenkbar an dem Flügel oder dem festen Rahmen anordenbar sein. Dadurch kann sie beim Öffnen des Flügels eine optimale, die Öffnungsbewegung unterstützende Stellung einnehmen.The spring device may preferably be pivotally attachable to the wing or fixed frame. As a result, when opening the sash, it can assume an optimum position which supports the opening movement.

Die Federvorrichtung kann beispielsweise lediglich über einen Bolzen schwenkbar am Flügel oder festen Rahmen angeordnet werden. Besonders bevorzugt ist es jedoch, wenn die Federvorrichtung schwenkbar an einem Befestigungsteil angeordnet ist, welches wiederum an dem festen Rahmen oder dem Flügel befestigbar ist. Dadurch wird die Stabilität der erfindungsgemäßen Anordnung erhöht.The spring device can be arranged, for example, only pivotable about a bolt on the wing or fixed frame. Especially However, it is preferred if the spring device is pivotally mounted on a fastening part, which in turn is fastened to the fixed frame or the wing. As a result, the stability of the arrangement according to the invention is increased.

Gemäß einer Ausgestaltung der Erfindung kann ein weiteres Federelement vorgesehen sein und die Federvorrichtung kann gegen die Federkraft des weiteren Federelements verschwenkbar sein. Somit kann die Federvorrichtung zunächst beim Öffnen des Flügels gegen die Federkraft des weiteren Federelements verschwenkt werden. Sobald die Federvorrichtung und das Spannelement entkoppelt sind, kann die Federvorrichtung durch die Federkraft des weiteren Federelements zurück verschwenkt werden, so dass die Federvorrichtung eine in etwa zu einem Rahmenholm oder Fensterholm parallele Ausrichtung einnimmt.According to one embodiment of the invention, a further spring element may be provided and the spring device may be pivotable against the spring force of the further spring element. Thus, the spring device can first be pivoted against the spring force of the further spring element when the wing is opened. Once the spring device and the tensioning element are decoupled, the spring device can be pivoted back by the spring force of the further spring element, so that the spring device assumes an approximately parallel to a frame spar or window spar alignment.

Die Federvorrichtung kann eine Hülse aufweisen, in der das Federelement angeordnet ist. Dadurch ist das Federelement zum einen geschützt angeordnet und zum anderen wird das Federelement durch die Hülse geführt. Vorzugsweise ist das Federelement unverlierbar in der Hülse angeordnet.The spring device may comprise a sleeve in which the spring element is arranged. As a result, the spring element is arranged protected on the one hand and on the other hand, the spring element is guided by the sleeve. Preferably, the spring element is arranged captive in the sleeve.

Besondere Vorteile ergeben sich, wenn die Hülse geschlitzt ist und das Spannelement zumindest in einem Betriebszustand in den Schlitz ragt.Particular advantages arise when the sleeve is slotted and the clamping element projects into the slot at least in an operating state.

Durch den Schlitz wird das Spannelement geführt, wenn das Spannelement das Federelement spannt. Außerdem definiert der Schlitz die relative Bewegung von Spannelement und Federvorrichtung, wenn sich das Federelement beim Öffnen des Flügels entspannt. Aufgrund des Schlitzes ist es möglich, dass das Spannelement relativ zur Hülse bewegt werden kann.Through the slot, the clamping element is guided when the clamping element biases the spring element. In addition, the slot defines the relative movement of the tensioning element and the spring device when the spring element relaxes when the wing is opened. Due to the slot, it is possible that the clamping element can be moved relative to the sleeve.

Das weitere Federelement kann beispielsweise als Blattfeder ausgebildet sein. Dabei kann sich das weitere Federelement an die Hülse der Federvorrichtung anschließen und an dem Befestigungsteil abstützen. Zu diesem Zweck kann die Hülse an einem Ende eine schlitzartige Ausnehmung aufweisen, in der das weitere Federelement angeordnet ist. Mit einer Blattfeder als weiterem Federelement kann eine Rückstellung der Federvorrichtung nach dem Lösen des Spannelements von der Federvorrichtung besonders einfach bewirkt werden. Außerdem ergibt sich mit einer Blattfeder als weiterem Federelement eine platzsparende Ausgestaltung der Anordnung, so dass diese problemlos im Falzluftbereich zwischen Flügel und festem Rahmen angeordnet werden kann.The further spring element may be formed, for example, as a leaf spring. In this case, the further spring element can connect to the sleeve of the spring device and be supported on the fastening part. For this purpose, the sleeve may have a slot-like recess at one end, in which the further spring element is arranged. With a leaf spring as a further spring element, a provision of the spring device after releasing the clamping element of the spring device can be particularly easily effected. In addition, with a leaf spring as a further spring element results in a space-saving design of the arrangement, so that it can be easily arranged in the rebate air range between wings and fixed frame.

Gemäß einer Ausgestaltung der Erfindung kann vorgesehen sein, dass die Hülse bei geschlossenem Flügel in einem Winkel α, 0 ≤ α ≤ 25°, zur Hauptebene des Fensters oder der Tür angeordnet ist. Eine besonders platzsparende Anordnung ergibt sich, wenn die Hülse parallel zum festen Rahmen beziehungsweise zum Flügelrahmen angeordnet ist, wenn der Flügel in einer Schließstellung ist. Die Unterstützung der Öffnungsbewegung kann jedoch effektiver sein, wenn die Hülse bei geschlossenem Flügel, insbesondere nach dem Spannen des Federelements in einem Winkel > 0° zur Hauptebene des Fensters oder der Tür angeordnet ist.According to one embodiment of the invention can be provided that the sleeve is arranged with the wing closed at an angle α, 0 ≤ α ≤ 25 ° to the main plane of the window or the door. A particularly space-saving arrangement results when the sleeve is arranged parallel to the fixed frame or to the casement, when the wing is in a closed position. However, the support of the opening movement can be more effective if the sleeve is arranged with the wing closed, in particular after tensioning the spring element at an angle> 0 ° to the main plane of the window or the door.

In den Rahmen der Erfindung fällt außerdem ein Fenster oder eine Tür mit einem festen Rahmen und einem relativ zum festen Rahmen zwischen zumindest einer Öffnungsstellung und einer Schließstellung bewegbaren Flügel und einem Beschlag zum Ver- und Entriegeln des Fensters oder der Tür sowie einer erfindungsgemäßen Anordnung, wobei das Spannelement mit dem Beschlag gekoppelt ist. Vorzugsweise handelt es sich bei dem Beschlag um einen Treibstangenbeschlag. Die Anordnung ist dabei vorzugsweise ebenfalls im Falzluftbereich zwischen Flügel und festem Rahmen angeordnet. Durch die Positionierung im Falzluftbereich ist die Anordnung bei geschlossenem Flügel unsichtbar. Beispielsweise kann es sich bei dem Fenster um ein Dreh-Kipp-Fenster handeln, d.h. um ein Fenster, bei dem der Flügel um eine vertikale Achse in eine Öffnungsstellung verschwenkt werden kann oder um eine horizontale Achse in eine Kipp-Öffnungsstellung verschwenkt werden kann. Alternativ kann die erfindungsgemäße Anordnung bei einer Kipp-Schiebetür zum Einsatz kommen.In the context of the invention also falls a window or door with a fixed frame and a relative to the fixed frame between at least one open position and a closed position movable wings and a fitting for locking and unlocking the window or the door and an inventive arrangement, wherein the clamping element is coupled to the fitting. Preferably, the fitting is a drive rod fitting. The arrangement is here preferably also arranged in the rabbet area between the wing and fixed frame. Due to the positioning in the rabbet air area, the arrangement with the wing closed is invisible. For example, the window can be a turn-tilt window, ie a window in which the wing can be pivoted about a vertical axis into an open position or can be pivoted about a horizontal axis into a tilt-open position. Alternatively, the arrangement according to the invention can be used with a tilt-sliding door.

In den Rahmen der Erfindung fällt weiterhin ein Verfahren zum unterstützten Öffnen eines Flügels eines Fensters oder einer Tür, wobei beim Entriegeln des Fensters oder der Tür ein Federelement einer Federvorrichtung gespannt wird und anschließend unter Entspannung des Federelements und Verschwenken der Federvorrichtung der Flügel geöffnet wird. Durch die Entspannung des Federelements wird der Kraftaufwand für einen Benutzer zum Öffnen des Flügels reduziert.In the scope of the invention further falls a method for assisted opening of a wing of a window or a door, wherein when unlocking the window or door, a spring element of a spring device is tensioned and then opened under relaxation of the spring element and pivoting of the spring device of the wing. By relaxing the spring element of the force required for a user to open the wing is reduced.

Gemäß einer Verfahrensvariante kann vorgesehen sein, dass nach Entspannung des Federelements ein Spannelement von der Federvorrichtung entkoppelt wird. Dies bedeutet, dass die Öffnungsbewegung des Flügels durch die Federvorrichtung nicht limitiert wird. Außerdem wird dadurch sichergestellt, dass das Federelement sowohl bei einer geöffneten Stellung des Flügels als auch bei einer geschlossenen Stellung des Flügels entspannt ist.According to a variant of the method can be provided that after relaxation of the spring element, a clamping element is decoupled from the spring device. This means that the opening movement of the wing is not limited by the spring device. In addition, this ensures that the spring element is relaxed both in an open position of the wing and in a closed position of the wing.

Gemäß einer weiteren Verfahrensvariante kann vorgesehen sein, dass nach Entkopplung von Spannelement und Federvorrichtung die Federvorrichtung federbeaufschlagt verschwenkt wird. Dadurch kann sichergestellt werden, dass die Federvorrichtung bei geöffnetem Flügel nicht quer zur Rahmenebene ausgerichtet ist sondern in etwa parallel zu dieser angeordnet ist. Dadurch kann eine Beschädigung der Federvorrichtung verhindert werden.According to a further variant of the method can be provided that after decoupling of clamping element and spring device, the spring device is pivoted spring loaded. This can ensure that the spring device with the wing open is not aligned transversely to the frame plane but is arranged approximately parallel to this. Thereby, damage to the spring device can be prevented.

Es kann weiterhin vorgesehen sein, dass beim Schließen des Flügels die Federvorrichtung an das Spannelement anschlägt und durch dieses ausgelenkt wird. Wird anschließend das Fenster oder die Tür verriegelt, d.h. der Beschlag in seine Verriegelungsstellung gebracht, gibt das Spannelement die Federvorrichtung frei und wird diese durch das weitere Federelement verschwenkt, so dass die Mündung des Schlitzes der Hülse der Federvorrichtung dem Spannelement gegenüber angeordnet ist, so dass dieses beim Entriegeln des Fensters oder der Tür wieder in den Schlitz der Hülse einfahren kann und dadurch das Federelement spannen kann.It can also be provided that when closing the wing, the spring device strikes against the clamping element and is deflected by this. Subsequently, when the window or door is locked, i. brought the fitting in its locking position, the clamping element releases the spring device and this is pivoted by the further spring element, so that the mouth of the slot of the sleeve of the spring device is arranged opposite the clamping element, so that this when unlocking the window or the door back in can retract the slot of the sleeve and thereby tension the spring element.

Die Figur 1 zeigt ein Fenster 1 mit einem festen Rahmen 2 und einem Flügel 3, der sich in der gezeigten Stellung in einer Kipp-Öffnungsstellung befindet. Im oberen Falzluftbereich ist eine erfindungsgemäße Anordnung 4 stark schematisiert dargestellt. Die erfindungsgemäße Anordnung 4 kann auch an jeder beliebigen anderen Seite des Fensters 1 angeordnet sein. Bei kipp-öffenbaren Flügeln ist eine bevorzugte Stelle jedoch im oberen Bereich des Fensters 1.The FIG. 1 shows a window 1 with a fixed frame 2 and a wing 3, which is in the position shown in a tilt-open position. In the upper Falzluftbereich an inventive arrangement 4 is shown in a highly schematic. The arrangement 4 according to the invention can also be arranged on any other side of the window 1. For tilt-openable wings, however, a preferred location is in the upper area of the window 1.

Die Figur 2 zeigt eine erfindungsgemäße Anordnung 4 bei geschlossenem, verriegeltem Flügel 3. Die Anordnung 4 weist eine Federvorrichtung 5 auf, die eine Hülse 6 umfasst, in der ein Federelement 7 angeordnet ist. Die Hülse 6 ist auf gegenüber liegenden Seiten geschlitzt ausgebildet, wobei in der gezeigten Darstellung lediglich der Schlitz 8 zu sehen ist. Die Federvorrichtung 5 ist schwenkbar an einem Befestigungsteil 9 angeordnet, welches im vorliegenden Fall am festen Rahmen 2 befestigt werden kann. In der gezeigten, der geschlossenen Stellung des Flügels entsprechenden Stellung, ist die Federvorrichtung 5 im Wesentlichen parallel zur Fensterebene ausgerichtet.The FIG. 2 shows an inventive arrangement 4 with closed, locked wing 3. The assembly 4 has a spring device 5, which comprises a sleeve 6, in which a spring element 7 is arranged. The sleeve 6 is formed slotted on opposite sides, in the illustration shown only the slot 8 can be seen. The spring device 5 is pivotable on a fastening part 9 arranged, which can be fixed in the present case on the fixed frame 2. In the illustrated, the closed position of the wing corresponding position, the spring device 5 is aligned substantially parallel to the window plane.

Mit geringem Abstand zur Federvorrichtung 5 ist ein als Zapfen ausgebildetes Spannelement 10 zu erkennen, welches mit einem Beschlag 11 des Fensters 1, insbesondere einer Treibstange 12 des Beschlags, gekoppelt ist. Beim Entriegeln des Fensters 1 wird die Treibstange 12 in Pfeilrichtung 13 bewegt. Dadurch gelangt das Spannelement 10 in den Schlitz 8 und in Anlage an das Federelement 7 beziehungsweise eine Abstützplatte 14 des Federelements 7. Bei einer Bewegung der Treibstange 12 in Pfeilrichtung 13 und damit einer Bewegung des Spannelements 10 in Pfeilrichtung 13 wird somit das Federelement 7 gespannt, wie dies in der Figur 3 zu erkennen ist. Hier ist weiterhin zu erkennen, dass allein das Spannen des Federelements 7 nicht zu einer Öffnungsbewegung des Flügels 3 führt. Wird dagegen der Flügel 3 von einem Benutzer aufgedrückt, so wird diese Öffnungsbewegung durch die Anordnung 4 unterstützt. Insbesondere wird dabei die Federvorrichtung 5 und insbesondere die Hülse 6 bezüglich des festen Rahmens 2 beziehungsweise des Befestigungsteils 9 verschwenkt, wie dies in der Figur 4 zu sehen ist. Gleichzeitig entspannt sich das Federelement 7, wodurch die Öffnungsbewegung unterstützt wird. Das Federelement 7 stützt sich dabei über die Abstützplatte 14 am Spannelement 10 ab.At a small distance from the spring device 5 is designed as a pin clamping element 10 can be seen, which is coupled to a fitting 11 of the window 1, in particular a drive rod 12 of the fitting. When unlocking the window 1, the drive rod 12 is moved in the direction of arrow 13. As a result, the clamping element 10 enters the slot 8 and in contact with the spring element 7 and a support plate 14 of the spring element 7. Upon movement of the drive rod 12 in the direction of arrow 13 and thus a movement of the clamping element 10 in the direction of arrow 13 thus the spring element 7 is tensioned, like this in the FIG. 3 can be seen. It can also be seen here that the tensioning of the spring element 7 alone does not lead to an opening movement of the wing 3. If, however, the wing 3 is pressed by a user, this opening movement is supported by the arrangement 4. In particular, while the spring device 5 and in particular the sleeve 6 is pivoted relative to the fixed frame 2 and the fastening part 9, as in the FIG. 4 you can see. At the same time, the spring element 7 relaxes, whereby the opening movement is supported. The spring element 7 is supported via the support plate 14 on the clamping element 10.

Wird der Flügel 3 weiter geöffnet, wird das Spannelement 10 von der Federvorrichtung 5 entkoppelt. Die Federvorrichtung 5 ist über ein weiteres Federelement 17 mit dem Befestigungsteil 9 gekoppelt. Sobald das Spannelement 10 von der Federvorrichtung 5 entkoppelt ist, kann das weitere Federelement 17 daher die Federvorrichtung 5 verschwenken, so dass diese eine Ausrichtung einnimmt, die in etwa parallel zur Rahmenebene liegt. Das weitere Federelement 17 kann beispielsweise als Blattfeder ausgebildet sein. Diese Situation ist in der Figur 5 gezeigt. Bei vollständig geöffnetem Flügel ist das Federelement 7, wie dies der Figur 5 zu entnehmen ist, entspannt.If the wing 3 is opened further, the tensioning element 10 is decoupled from the spring device 5. The spring device 5 is coupled via a further spring element 17 with the fastening part 9. As soon as the tensioning element 10 is decoupled from the spring device 5, the further spring element 17 can therefore pivot the spring device 5, then that it occupies an orientation which is approximately parallel to the frame plane. The further spring element 17 may be formed, for example, as a leaf spring. This situation is in the FIG. 5 shown. When fully open wing is the spring element 7, as is the FIG. 5 it can be seen, relaxed.

Wird der Flügel 3 anschließend wieder geschlossen, so befindet sich der Beschlag 11 noch in einer Entriegelungsposition. Somit stößt die Federvorrichtung 5 an das Spannelement 10 an und wird entgegen der Federkraft des weiteren Federelements 17 ausgelenkt, wie dies in der Figur 6 zu sehen ist. Wird anschließend das Fenster 1 verriegelt und demnach das Spannelement 10 in Pfeilrichtung 18 bewegt, wird die Federvorrichtung 5 frei gegeben und kann durch die Wirkung des weiteren Federelements 17 wieder die ursprüngliche in der Figur 2 gezeigte Position einnehmen, in der das Spannelement 10 vor der Mündung des Schlitzes 8 angeordnet ist.If the wing 3 is then closed again, then the fitting 11 is still in an unlocked position. Thus, the spring device 5 abuts against the clamping element 10 and is deflected against the spring force of the further spring element 17, as shown in the FIG. 6 you can see. If then the window 1 is locked and therefore the clamping element 10 is moved in the direction of arrow 18, the spring device 5 is released and can by the action of the further spring element 17 back to the original in the FIG. 2 occupy shown position in which the clamping element 10 is arranged in front of the mouth of the slot 8.

In der Figur 7 ist die erfindungsgemäße Anordnung in einer Explosionsdarstellung gezeigt. Zusätzlich zu den vorher bereits beschriebenen Elementen ist ein Bolzen 20 zu sehen, über den die Hülse 6 schwenkbar an dem Befestigungsteil 9 angeordnet ist. Außerdem ist zu erkennen, dass die Hülse 6 einen geschlitzten Fortsatz 21 aufweist, der das weitere Federelement 17 aufnimmt. Insbesondere kann das weitere Federelements 17, welches als Blattfeder ausgebildet ist, lediglich in den geschlitzten Fortsatz 21 eingesteckt werden. Die Verwendung einer Blattfeder hat den Vorteil, dass die Federvorrichtung 5 in zwei unterschiedliche Richtungen entgegen einer Federkraft ausgelenkt werden kann.In the FIG. 7 the arrangement according to the invention is shown in an exploded view. In addition to the previously described elements, a bolt 20 can be seen, over which the sleeve 6 is pivotally mounted on the fastening part 9. In addition, it can be seen that the sleeve 6 has a slotted extension 21 which receives the further spring element 17. In particular, the further spring element 17, which is designed as a leaf spring, can only be inserted into the slotted extension 21. The use of a leaf spring has the advantage that the spring device 5 can be deflected in two different directions against a spring force.

Weiterhin ist zu erkennen, dass die Hülse 6 einen Anschlag 22 aufweist, an den die Abstützplatte 14 anschlagen kann, wenn sich das Federelement 7 in einer entspannten Stellung befindet. Es versteht sich, dass der Schlitz 8 so bemessen ist, dass er etwas breiter ist als der Durchmesser des Spannelements 10. Das Spannelement 10 weist eine Platte 23 auf, mit der es auf einer geschlitzten Stulpschiene 24 aufliegen kann. Ein Koppelabschnitt 25 dient der Kopplung mit der Treibstange 12 beziehungsweise dem Beschlag 11. nicht zu sehen ist eine Aufnahme beziehungsweise ein Anschlag für das freie Ende des weiteren Federelements 17 an der Unterseite des Befestigungsteils 9.Furthermore, it can be seen that the sleeve 6 has a stop 22 against which the support plate 14 can strike when the spring element 7 is in a relaxed position. It is understood that the slot 8 is dimensioned so that it is slightly wider than the diameter of the clamping element 10. The clamping element 10 has a plate 23 with which it can rest on a slotted cuff rail 24. A coupling portion 25 is used to couple with the drive rod 12 and the fitting 11 is not a recording or a stop for the free end of the further spring element 17 on the underside of the fastening part. 9
