Description

Die Erfindung betrifft ein Möbel mit einer Ausstoßvorrichtung für eine Falttür oder Falt-Schiebe-Tür, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a piece of furniture with an ejection device for a folding door or folding sliding door, according to the preamble of claim 1.

Eine Ausstoßvorrichtung der angegebenen Art ist aus der österreichischen Anmeldung A 855/2014 der Anmelderin bekannt. Nachteilig an dieser Ausstoßvorrichtung ist, dass sie am Möbelkorpus montiert ist und damit bei geöffneter Falttür oder Falt-Schiebetür die Zugänglichkeit des Inneren des Möbels erschwert. Außerdem beeinträchtigt die Ausstoßvorrichtung den ästhetischen Gesamteindruck. Und schließlich haben sich auch die Kräfteverhältnisse beim Laden des Kraftspeichers als nachteilig erwiesen.An ejection device of the specified type is from the Austrian application A 855/2014 known to the applicant. A disadvantage of this ejection device is that it is mounted on the furniture body and thus makes it more difficult to access the interior of the furniture when the folding door or folding sliding door is open. In addition, the ejection device affects the overall aesthetic impression. And finally, the balance of power when loading the energy accumulator has also proven to be disadvantageous.

Eine weitere Ausstoßvorrichtung wird durch das Dokument JP 2011-16 29 94 A offenbart. Darin wird eine Vorrichtung zum Aufknicken einer Falttür, bestehend aus zwei gelenkig miteinander verbundenen Türflügeln, aus einer Schließstellung in eine Offenstellung gezeigt. Zum Aufknicken dient dabei ein Ausstoßelement, das durch einen manuell von einem Benutzer zu ladenden Kraftspeicher beaufschlagbar ist. Die Ausstoßvorrichtung weist außerdem eine Verriegelungsvorrichtung zur lösbaren Verriegelung des Ausstoßelementes entgegen der Beaufschlagung durch den geladenen Kraftspeicher auf, wobei die Verriegelungsvorrichtung bei montierter Ausstoßvorrichtung durch Druckausübung auf die Falttür entriegelbar ist. Das Ausstoßelement stellt hierbei zugleich auch ein bewegbar gelagertes Ladeelement zum Laden des Kraftspeichers dar.Another ejection device is provided by the document JP 2011-16 29 94 A disclosed. It shows a device for folding a folding door, consisting of two hinged door panels, from a closed position into an open position. An ejection element, which can be acted upon by an energy store that is to be loaded manually by a user, is used for kinking. The ejection device also has a locking device for releasably locking the ejection element against the action of the loaded energy accumulator, the locking device being unlockable by exerting pressure on the folding door when the ejection device is installed. The ejection element also represents a movably mounted loading element for loading the energy accumulator.

Die Aufgabe der vorliegenden Erfindung besteht daher darin, ein gegenüber dem Stand der Technik verbessertes Möbel mit wenigstens einer Ausstoßvorrichtung anzugeben, wobei die Ausstoßvorrichtung insbesondere die vorbeschriebenen Nachteile behebt.The object of the present invention is therefore to provide a piece of furniture which is improved compared to the prior art and has at least one ejection device, the ejection device in particular eliminating the disadvantages described above.

Diese Aufgabe wird gelöst durch die Merkmale des unabhängigen Anspruchs 1.This object is achieved by the features of independent claim 1.

Es ist also vorgesehen, dass das wenigstens eine Ausstoßelement und das wenigstens eine Ladeelement als räumlich getrennte Baueinheiten ausgebildet sind. Dadurch kann in vorteilhafter Weise die Hebelwirkung der Tür zum Laden des wenigstens einen Kraftspeichers ausgenutzt werden. Darüber hinaus ist es möglich, die Ausstoßvorrichtung an einem der beiden Türflügel anzuordnen, sodass die Ausstoßvorrichtung beim Öffnen der Falttür oder Falt-Schiebe-Tür zwischen den beiden zusammengefalteten Türflügeln verschwindet und somit weder die Zugänglichkeit des Innenraums eines Möbels, noch den ästhetischen Gesamteindruck beeinträchtigen kann.It is therefore provided that the at least one ejection element and the at least one loading element are designed as spatially separate structural units. As a result, the lever action of the door for loading the at least one energy accumulator can be exploited in an advantageous manner. In addition, it is possible to arrange the ejection device on one of the two door leaves, so that when the folding door or folding sliding door is opened, the ejection device disappears between the two folded door leaves and thus can neither impair the accessibility of the interior of a piece of furniture nor the overall aesthetic impression .

Vorteilhafte Ausgestaltungen des erfindungsgemäßen Möbels mit wenigstens einer Ausstoßvorrichtung sind in den abhängigen Ansprüchen 2 bis 12 definiert.Advantageous embodiments of the furniture according to the invention with at least one ejection device are defined in the dependent claims 2 to 12.

Insbesondere ist es vorgesehen, dass die Ausstoßvorrichtung spiegelsymmetrisch ausgebildet ist. Dadurch kann die Ausstoßvorrichtung universell sowohl bei einer nach rechts als auch bei einer nach links öffnenden Falttür oder Falt-Schiebe-Tür eingesetzt werden.In particular, it is provided that the ejection device is mirror-symmetrical. As a result, the ejection device can be used universally both in the case of a folding door or a folding sliding door opening to the left.

Figur 1a) zeigt ein Möbel 27 mit einem Möbelkorpus 16 und einer Falt-Schiebe-Tür 2, welche zwei gelenkig miteinander verbundene Türflügel 3 und 4 umfasst. Die Falt-Schiebe-Tür 2 befindet sich in einer Schließstellung, in welcher die zwei Türflügel 3 und 4 in einer gemeinsamen Schließebene angeordnet sind. In dem Möbelkorpus 16 ist ein Hohlraum 28 zur Aufnahme der Falt-Schiebe-Tür 2 in einer zusammengefalteten Stellung ausgebildet. Der Hohlraum 28 ist schachtförmig und in einem Randbereich des Möbelkorpus 16 angeordnet. Figure 1a ) shows a piece of furniture 27 with a furniture body 16 and a folding-sliding door 2, which comprises two hinged door leaves 3 and 4. The folding sliding door 2 is in a closed position, in which the two door leaves 3 and 4 are arranged in a common closing plane. In the furniture body 16, a cavity 28 for receiving the folding sliding door 2 is formed in a folded position. The cavity 28 is shaft-shaped and arranged in an edge region of the furniture body 16.

Figur 1b) zeigt das Möbel gemäß Figur 1a) in einer Draufsicht von oben. An der Falt-Schiebe-Tür ist eine Ausstoßvorrichtung 1 angeordnet, welche in den nachfolgenden Figuren 1c) bis 1e) näher beschrieben wird:
Die Ausstoßvorrichtung 1 ist an der dem Möbelkorpus 16 bzw. dem Möbelinneren zugewandten Seite des Türflügels 3 angeordnet. Die Hinterkante dieses Türflügels 3 ist mittels einer gestrichelten Linie 30 angedeutet. Die Ausstoßvorrichtung 1 umfasst ein Ausstoßelement 5 zum Aufknicken der Falt-Schiebe-Tür aus der Schließstellung in eine Offenstellung, in welcher die zwei Türflügel einen Winkel ungleich 180° zueinander einschließen.
Figure 1b ) shows the furniture according to Figure 1a ) in a top view from above. On the folding sliding door, an ejection device 1 is arranged, which in the following Figures 1c) to 1e ) is described in more detail:
The ejection device 1 is arranged on the side of the door leaf 3 facing the furniture body 16 or the interior of the furniture. The rear edge of this door leaf 3 is indicated by a dashed line 30. The ejection device 1 comprises an ejection element 5 for folding the folding-sliding door out of the closed position into an open position, in which the two door leaves enclose an angle not equal to 180 ° to one another.

Das Ausstoßelement 5 weist ein Abstützelement 14 zum Abstützen an einer Stirnseite 17 des Möbelkorpus 16, genauer gesagt der Deckenblende des Möbelkorpus, beim Aufknicken der Falt-Schiebe-Tür auf, wobei das Abstützelement 14 als Wälzkörper in Form einer Rolle ausgebildet ist.The ejection element 5 has a support element 14 for support on an end face 17 of the furniture body 16, more precisely the ceiling panel of the furniture body, when the folding-sliding door is bent, the support element 14 being designed as a rolling element in the form of a roller.

Der Abstand zwischen der Hinterkante 30 des Türflügels 3 und der Deckenblende 17 ist mit dem Bezugszeichen 31 versehen und beträgt ca. 15 mm. Die Ausstoßeinheit 1 weist darüber hinaus gehende Bauteile, z.B. 24, 25 und 13 auf, die maximal ca. 45 mm in den Stau- bzw. Arbeitsbereich des Möbels hineinstehen. Diese Distanz ist mit dem Bezugszeichen 32 versehen.The distance between the rear edge 30 of the door leaf 3 and the ceiling panel 17 is provided with the reference number 31 and is approximately 15 mm. The ejection unit 1 also has additional components, e.g. 24, 25 and 13, which protrude a maximum of approx. 45 mm into the storage or working area of the furniture. This distance is provided with the reference number 32.

In der Figur 1d) ist eine Symmetrieebene 33 eingezeichnet, die durch die Mittellängsachse der Ausstoßeinheit 1 verläuft und zu der die Ausstoßvorrichtung 1 spiegelsymmetrisch ausgebildet ist. Die spiegelsymmetrische Ausbildung hat den Vorteil, dass die Ausstoßeinheit 1 sowohl bei einer Falt-Schiebe-Tür 2 wie in Figur 1a) dargestellt, als auch bei einer Falt-Schiebe-Tür, die links davon angeordnet ist und sich nach links öffnen lässt, eingesetzt werden kann. Hierzu muss die Ausstoßeinheit 1 lediglich um 180° gewendet werden. Für die Funktionsweise der Ausstoßeinheit 1 wäre jedoch auch eine der beiden spiegelsymmetrischen Hälften ausreichend.In the Figure 1d ), a plane of symmetry 33 is drawn in, which runs through the central longitudinal axis of the ejection unit 1 and to which the ejection device 1 is mirror-symmetrical. The mirror-symmetrical design has the advantage that the ejection unit 1 both in a folding and sliding door 2 as in Figure 1a ) shown, as well as with a folding sliding door, which is arranged to the left of it and can be opened to the left. For this purpose, the ejection unit 1 only has to be turned through 180 °. However, one of the two mirror-symmetrical halves would also be sufficient for the functioning of the ejection unit 1.

Im Einzelnen ist die Ausstoßeinheit 1 wie folgt aufgebaut: Die Ausstoßeinheit 1 umfasst eine Basis 29, über welche die Ausstoßeinheit 1 an einer Falttür oder Falt-Schiebe-Tür montierbar ist. Im vorliegenden Fall ist die Ausstoßeinheit 1 über die Basis 29 an dem Türflügel 3 der Falt-Schiebe-Tür 2 montiert. An der Basis 29 sind zwei Ausstoßelemente 5 und 6 angeordnet, die als schwenkbar gelagerte Ausstoßhebel ausgebildet sind. Die Ausstoßelemente 5 und 6 umfassen jeweils eine Basis 54, an welcher ein erster Schlitten 53 verschiebbar gelagert ist. Gegenüber der Basis 54 ist der Schlitten 53 durch einen ersten Kraftspeicher 9 in Form zweier paralleler Zugfedern mit einer Kraft beaufschlagbar. Am freien Ende des verfahrbaren Schlittens 53 sind zwei Wälzkörper in Form von Rollen angeordnet, und zwar zum einen das Abstützelement 14 zum Abstützen an dem Möbelkorpus und zum anderen eine Rolle 51, die sich an einer Schrägfläche 22 zur Initiierung der Aufknickbewegung des Ausstoßelements 5 abstützen kann. Im Falle des identisch ausgebildeten Ausstoßelements 6 sind die beiden Rollen mit den Bezugszeichen 15 und 52 und die Schrägfläche, an der sich die Rolle 52 zu Beginn der Aufknickbewegung abstützen kann, mit dem Bezugszeichen 23 versehen.In detail, the ejection unit 1 is constructed as follows: The ejection unit 1 comprises a base 29, via which the ejection unit 1 can be mounted on a folding door or folding sliding door. In the present case, the ejection unit 1 is mounted on the door leaf 3 of the folding-sliding door 2 via the base 29. Arranged on the base 29 are two ejection elements 5 and 6 which are designed as pivotably mounted ejection levers. The ejection elements 5 and 6 each comprise a base 54, on which a first carriage 53 is slidably mounted. Compared to the base 54, the carriage 53 is by a first energy accumulator 9 in the form of two parallel tension springs can be loaded with a force. At the free end of the movable carriage 53, two rolling elements in the form of rollers are arranged, on the one hand the support element 14 for support on the furniture body and on the other hand a roller 51, which can be supported on an inclined surface 22 to initiate the buckling movement of the ejection element 5 . In the case of the identically designed ejection element 6, the two rollers are provided with the reference symbols 15 and 52 and the inclined surface on which the roller 52 can be supported at the beginning of the buckling movement is provided with the reference symbol 23.

An der Basis 54 der Ausstoßelemente 5 bzw. 6 ist neben dem Schlitten 53 noch ein weiterer Schlitten 56 verschiebbar gelagert, der ebenfalls über einen Kraftspeicher in Form einer Zugfeder 57 gegenüber der Basis 54 mit Kraft beaufschlagbar ist. Der Schlitten 56 dient zusammen mit einer Druckfeder 58, die auf eine Feststellvorrichtung 40 wirkt, und einem Bolzen 55 dazu den Angriffswinkel 26 (vgl. Fig. 1c)) eines Kraftumlenkhebels 24, 25 an den Ausstoßelementen 5 und 6 lösbar zu fixieren. Die Funktionsweise dieser Feststellvorrichtung wird in Zusammenhang mit den Figuren 8c), 9b), 10c) und 13b) näher beschrieben.On the base 54 of the ejection elements 5 and 6, in addition to the slide 53, a further slide 56 is slidably mounted, which can also be acted upon by a force accumulator in the form of a tension spring 57 relative to the base 54. Together with a compression spring 58, which acts on a locking device 40, and a bolt 55, the carriage 56 serves the angle of attack 26 (cf. Fig. 1c )) a power lever 24, 25 releasably fix to the ejection elements 5 and 6. The operation of this locking device is in connection with the Figures 8c ), 9b ), 10c ) and 13b ) described in more detail.

Die Schlitten 53 der Ausstoßelemente 5 und 6 sind über ein Verbindungselement 43 miteinander bewegungsgekoppelt.The slides 53 of the ejection elements 5 and 6 are motionally coupled to one another via a connecting element 43.

Neben dem Kraftspeicher 9 ist auch noch ein weiterer unabhängiger Kraftspeicher 8 in Form zweier Zugfedern zur Beaufschlagung der Ausstoßelemente 5 und 6 vorgesehen, wobei die Kraftbeaufschlagung über einen Kraftumlenkhebel erfolgt, der an dem Schlitten 56 drehbar gelagert ist und aus einem ersten plattenförmigen Bauteil 25 und zwei gelenkig daran angelenkten Armen 24 aufgebaut ist. Die Arme 24 sind mit ihrem anderen Ende an einem linear verfahrbaren Schlitten 34, der an der Basis 29 linear verfahrbar ist, drehbar gelagert. Die Zugfedern 8 sind über Aufhängungen 35 einerseits an dem Linearschlitten 34 und andererseits an der Basis 29 aufgehängt.In addition to the energy accumulator 9, a further independent energy accumulator 8 is also provided in the form of two tension springs for acting on the ejection elements 5 and 6, the force being applied via a force deflection lever which is rotatably mounted on the carriage 56 and consists of a first plate-shaped component 25 and two hinged arms 24 is constructed. The arms 24 are rotatably supported at their other end on a linearly movable carriage 34 which is linearly movable on the base 29. The tension springs 8 are suspended via suspensions 35 on the one hand on the linear slide 34 and on the other hand on the base 29.

Bei fixiertem Angriffswinkel 26 des Kraftumlenkhebels 24, 25 an den Ausstoßelementen 5 und 6 steht der Kraftumlenkhebel 24, 25 in einer Seitenansicht betrachtet (vgl. Fig. 1c)) knieförmig von der Ausstoßvorrichtung 1 ab.When the angle of attack 26 of the power deflection lever 24, 25 on the ejection elements 5 and 6 is fixed, the power deflection lever 24, 25 is viewed in a side view (cf. Fig. 1c )) from the ejection device 1 in a knee shape.

Die Ausstoßvorrichtung 1 umfasst weiterhin zwei Verriegelungsvorrichtungen 10 und 11 zur lösbaren Verriegelung der Ausstoßelemente 5 und 6 entgegen der Beaufschlagung durch die geladenen Kraftspeicher 8 und 9. Der Aufbau und die Funktionsweise der Verriegelungsvorrichtungen 10 und 11 wird in Zusammenhang mit den Figuren 2c) bis 2h) näher erläutert.The ejection device 1 further comprises two locking devices 10 and 11 for releasably locking the ejection elements 5 and 6 against the action of the loaded energy accumulators 8 and 9. The structure and the mode of operation of the locking devices 10 and 11 are described in connection with FIGS Figures 2c) to 2h ) explained in more detail.

An der Basis 29 der Ausstoßvorrichtung 1 ist weiterhin ein Ladeelement 13 bewegbar gelagert, wobei dieses Ladeelement 13 als schwenkbar gelagerter Ladehebel ausgebildet ist. Das Ladeelement 13 wird gegenüber der Basis 29 mittels eines Kraftspeichers in Form zweier Schenkelfedern 42 in der Stellung, die in den Figuren 1c) und 1d) gezeigt ist, gehalten.A loading element 13 is also movably mounted on the base 29 of the ejection device 1, this loading element 13 being designed as a pivotably mounted loading lever. The loading element 13 is in relation to the base 29 by means of an energy store in the form of two leg springs 42 in the position which in the Figures 1c) and 1d ) is shown.

Die Ausstoßelemente 5 und 6, sowie das Ladeelement 13, sind über eine Synchronisierungsvorrichtung 18 miteinander bewegungsgekoppelt. Die Synchronisierungsvorrichtung 18 umfasst eine Verzahnung in Form eines an der Basis 29 über ein Gehäuse 37 drehbar gelagerten Zahnrads 20, welches einerseits eine an einem Linearschlitten 38 angeordnete Zahnstange 19 und andererseits eine an einem Linearschlitten 39 angeordnete Zahnstange 21 kämmt. Der Linearschlitten 39 ist über ein Verbindungselement 41 mit dem Ladeelement 13 gekoppelt. Der Linearschlitten 38 kann über eine Sperrklinke 36 mit dem Linearschlitten 34 gekoppelt werden. Dazu rastet die Sperrklinke 36 mit einem Zapfen in eine Öffnung 67 in dem Linearschlitten 38 ein. Details zu dieser Kopplung der Schlitten 34 und 38 werden in Zusammenhang mit den Figuren 9c) und 13c) näher erläutert.The ejection elements 5 and 6, as well as the loading element 13, are motionally coupled to one another via a synchronization device 18. The synchronization device 18 comprises a toothing in the form of a gearwheel 20 which is rotatably mounted on the base 29 via a housing 37 and which meshes on the one hand with a rack 19 arranged on a linear slide 38 and on the other hand with a rack 21 arranged on a linear slide 39. The linear slide 39 is coupled to the charging element 13 via a connecting element 41. The linear slide 38 can be coupled to the linear slide 34 via a pawl 36. For this purpose, the pawl 36 engages with a pin in an opening 67 in the linear slide 38. Details on this coupling of the slides 34 and 38 are given in connection with the Figures 9c ) and 13c ) explained in more detail.

In dem in den Figuren 1c) und 1d) gezeigten Zustand, den die Ausstoßvorrichtung 1 in der Schließstellung der Falt-Schiebe-Tür 2 einnimmt, sind die Kraftspeicher 8 und 9 vollständig geladen und die Ausstoßelemente 5 und 6 über die Verriegelungsvorrichtungen 10 und 11 entgegen der Beaufschlagung durch die geladenen Kraftspeicher 8 und 9 verriegelt. Der Angriffswinkel des Kraftumlenkhebels 24, 25 an den Ausstoßelementen 5 und 6 ist darüber hinaus fixiert.In the in the Figures 1c) and 1d ) shown state, which the ejection device 1 assumes in the closed position of the folding sliding door 2, the energy stores 8 and 9 are fully loaded and the ejection elements 5 and 6 via the locking devices 10 and 11 against the action of the loaded energy stores 8 and 9 locked. The angle of attack of the power lever 24, 25 on the ejection elements 5 and 6 is also fixed.

Zur Entriegelung der Verriegelungsvorrichtungen 10 und 11 übt ein Benutzer Druck auf die Falt-Schiebe-Tür 2 aus (vgl. Fig. 2a). Dadurch wird die Falt-Schiebe-Tür 2 in eine Überdrückstellung gebracht. Die Druckausübung erfolgt vorteilhafterweise in dem Bereich 12, in welchem die zwei Türflügel 3 und 4 gelenkig miteinander verbunden sind. In dem gezeigten Ausführungsbeispiel beträgt der Auslöseweg 2 mm.To unlock the locking devices 10 and 11, a user exerts pressure on the folding sliding door 2 (cf. Fig. 2a ). As a result, the folding sliding door 2 is brought into an overpressure position. The pressure is advantageously applied in the Area 12 in which the two door leaves 3 and 4 are connected to one another in an articulated manner. In the exemplary embodiment shown, the trigger path is 2 mm.

Da die Ausstoßeinheit 1 an der Falt-Schiebe-Tür 2 montiert ist und sich gleichzeitig über das Abstützelement 14 an der Stirnseite 17 des Möbelkorpus 16 abstützt, wird durch die Druckausübung auf die Falt-Schiebe-Tür 2 das Ausstoßelement 5 und indirekt in weiterer Folge, da das Verbindungselement 43 zwischen den beiden Ausstoßelementen 5 und 6 in Nuten 59 eines Rastkeils 44 der Verriegelungsvorrichtung 10 und 11 im verriegelten Zustand eingreift, dieser Rastkeil 44 nach unten, d.h. in Richtung der Türflügel 3 und 4 der Falt-Schiebe-Tür 2, gedrückt.Since the ejection unit 1 is mounted on the folding-sliding door 2 and is supported at the same time via the support element 14 on the end face 17 of the furniture body 16, the ejection element 5 becomes indirect and subsequently in consequence of the pressure on the folding-sliding door 2 , since the connecting element 43 between the two ejection elements 5 and 6 engages in grooves 59 of a locking wedge 44 of the locking device 10 and 11 in the locked state, this locking wedge 44 downwards, ie in the direction of door leaves 3 and 4 of the folding sliding door 2.

Wie aus den Figuren 2c) bis 2h) hervorgeht, wirkt der Rastkeil 44 über eine in einer Führungsnut 61 gelagerten Kugel 50 mit einer herzkurvenförmigen Verriegelungsbahn 60, die in einem Basiselement 48 ausgebildet ist, zusammen, wobei der Rastkeil 44 in der verriegelten Stellung, in welcher sich die Kugel 50 in der Herzmulde befindet, gegenüber dem Basiselement 48 über eine Druckfeder 45 kraftbeaufschlagt ist. Durch die Entriegelungsbewegung des Rastkeils 44 bewegt sich die Kugel 50 aus der Herzmulde hinaus und die Verriegelung wird aufgehoben. In weiterer Folge bewegt sich der Rastkeil 44 von den Türflügeln 3 und 4 der Falt-Schiebe-Tür 2 schräg nach oben unter der Wirkung der in der Druckfeder 45 gespeicherten Kraft weg und gibt den Weg für das Verbindungselement 43 und damit für die Ausstoßelemente 5 und 6 frei. Das Basiselement 48 sowie die Druckfeder 45 und der Rastkeil 44 sind durch zwei Gehäuseteile 47 und 49 erhalten.Like from the Figures 2c) to 2h ), the locking wedge 44 interacts via a ball 50 mounted in a guide groove 61 with a heart-shaped locking track 60 which is formed in a base element 48, the locking wedge 44 in the locked position in which the ball 50 is in the heart cavity located, is acted upon by a compression spring 45 relative to the base element 48. Due to the unlocking movement of the locking wedge 44, the ball 50 moves out of the heart cavity and the locking is released. Subsequently, the locking wedge 44 moves away from the door leaves 3 and 4 of the folding-sliding door 2 at an angle upwards under the action of the force stored in the compression spring 45 and gives the path for the connecting element 43 and thus for the ejection elements 5 and 6 free. The base element 48 and the compression spring 45 and the locking wedge 44 are obtained by two housing parts 47 and 49.

Durch die Entriegelung wird das Verbindungselement 43 und damit die Ausstoßelemente 5 und 6 freigegeben. Das hat zur Folge, dass der Linearschlitten 53 gegenüber der Basis 54 unter Freiwerdung der im Kraftspeicher 9 gespeicherten Energie ausfahren kann (vgl. Figuren 3b) und 3c)). Dabei gleiten die Ausstoßelemente 5 und 6 über die Rollen 51 bzw. 52 an den Schrägflächen 22 bzw. 23 entlang, wodurch die Ausfahrbewegung des Schlittens 53 in eine Schwenkbewegung der Ausstoßelemente 5 und 6 umgesetzt wird. Die Höhe 69 der Schrägflächen 22 und 23 beträgt 20 mm. Da sich die Ausstoßelemente 5 und 6 mittels der Abstützelemente 14 und 15 gleichzeitig an dem Möbelkorpus abstützen, erfolgt ein Aufknicken der Falt-Schiebe-Tür 2 (vgl. Figur 3a)). Die Schrägflächen 22 und 23 dienen also zur Initiierung der Aufknickbewegung der Ausstoßelemente 5 und 6.By unlocking the connecting element 43 and thus the ejection elements 5 and 6 are released. The result of this is that the linear slide 53 can extend relative to the base 54, releasing the energy stored in the energy store 9 (cf. Figures 3b ) and 3c )). The ejection elements 5 and 6 slide over the rollers 51 and 52 along the inclined surfaces 22 and 23, as a result of which the extension movement of the carriage 53 is converted into a pivoting movement of the ejection elements 5 and 6. The height 69 of the inclined surfaces 22 and 23 is 20 mm. Since the ejection elements 5 and 6 are simultaneously supported on the furniture body by means of the support elements 14 and 15, the folding-sliding door is bent 2 (cf. Figure 3a )). The inclined surfaces 22 and 23 thus serve to initiate the buckling movement of the ejection elements 5 and 6.

In Zusammenhang mit der Figur 3a) sei noch darauf hingewiesen, dass der Türflügel 4 der Falt-Schiebe-Tür 2 über Scharniere 64 an dem Möbelkorpus gelenkig angeordnet ist, die Türflügel 3 und 4 über Scharniere 63 gelenkig miteinander verbunden sind und der Türflügel 3 mittels eines Laufwagens 62 verschiebbar an Führungselementen 65, die am Möbelkorpus vorgesehen sind, gelagert ist.In connection with the Figure 3a ) It should also be pointed out that the door leaf 4 of the folding-sliding door 2 is articulated via hinges 64 on the furniture body, the door leaves 3 and 4 are articulated to one another via hinges 63 and the door leaf 3 can be moved on guide elements by means of a carriage 62 65, which are provided on the furniture body, is mounted.

Die Ausstoßelemente 5 und 6 sowie das schwenkbar gelagerte Ladeelement 13 sind über die Synchronisationsvorrichtung 18 bewegungsgekoppelt und zwar derart, dass ein Verschwenken der Ausstoßelemente 5 und 6 ein gegensinniges Verschwenken des Ladelementes 13 - und umgekehrt - zur Folge hat, was in der Figur 3b) durch die im und gegen den Uhrzeigersinn weisenden Pfeile angedeutet ist.The ejection elements 5 and 6 as well as the pivotably mounted loading element 13 are motion-coupled via the synchronization device 18 in such a way that pivoting the ejection elements 5 and 6 results in the opposite pivoting of the loading element 13 - and vice versa - which in the Figure 3b ) is indicated by the arrows pointing clockwise and counterclockwise.

Sobald die Schlitten 53 zumindest teilweise aus der Basis 54 herausgefahren sind und dadurch die Ausstoßelemente 5 und 6 über die Schrägflächen 22 und 23 verschwenkt sind, kann die im Kraftspeicher 8 gespeicherte Energie über den Kraftumlenkhebel 24 und 25 wirksam werden. Das bedeutet, dass während der Initiierung der Aufknickbewegung der Ausstoßelemente 5 und 6 zunächst hauptsächlich die im Kraftspeicher 9 gespeicherte Energie frei wird und anschließend hauptsächlich bzw. nach dem vollständigen Ausfahren der Schlitten 53 ausschließlich die im unabhängigen Kraftspeicher 8 gespeicherte Energie frei wird, was zu einem weiteren Verschwenken der Ausstoßelemente 5 und 6 und damit zu einem weiteren Aufknicken der Falt-Schiebe-Tür 2 führt.As soon as the slides 53 are at least partially moved out of the base 54 and the ejection elements 5 and 6 are thereby pivoted over the inclined surfaces 22 and 23, the energy stored in the energy accumulator 8 can take effect via the force deflection lever 24 and 25. This means that during the initiation of the bend-in movement of the ejection elements 5 and 6, primarily the energy stored in the energy store 9 is initially released, and then mainly or after the carriage 53 has been fully extended, only the energy stored in the independent energy store 8 is released, resulting in a further pivoting of the ejection elements 5 and 6 and thus leads to a further kinking of the folding sliding door 2.

Die Figuren 4a) und 4b) zeigen eine Zwischenstellung der Falt-Schiebe-Tür im Zuge dieser Aufknickbewegung.The Figures 4a) and 4b ) show an intermediate position of the folding sliding door in the course of this folding movement.

Die Figuren 5a) und 5b) zeigen die Stellung der Falt-Schiebe-Tür 2 bzw. der Ausstoßvorrichtung 1 am Ende des Aufknickens der Falt-Schiebe-Tür 2 aus der Schließstellung, in welcher die zwei Türflügel 3 und 4 in einer gemeinsamen Schließebene angeordnet sind, in eine Offenstellung, in welcher die zwei Türflügel 3 und 4 einen Winkel 7 ungleich 180° zueinander einschließen. Im konkreten Fall beträgt dieser Winkel 7 ca. 150°.The Figures 5a) and 5b ) show the position of the folding sliding door 2 or the ejection device 1 at the end of the folding of the folding sliding door 2 from the closed position, in which the two door leaves 3 and 4 are arranged in a common closing plane, into an open position, in which the two door leaves 3 and 4 enclose an angle 7 not equal to 180 ° to one another. In the specific case, this angle 7 is approximately 150 °.

Die Kraftspeicher 8 und 9 sind im Wesentlichen entladen, die Schlitten 53 maximal gegenüber den Basen 54 herausgefahren und der Linearschlitten 34 (vgl. auch die Figur 1e)) hat durch die Entladung des Kraftspeichers 8 seine Endstellung gegenüber dem Gehäuse 29 der Ausstoßvorrichtung 1 erreicht. Die Ausstoßelemente 5 und 6 können daher nicht weiter verschwenkt werden.The energy accumulators 8 and 9 are essentially unloaded, the slides 53 are maximally moved out relative to the bases 54 and the linear slide 34 (cf. also FIG Figure 1e )) has reached its end position relative to the housing 29 of the ejection device 1 by the discharge of the energy accumulator 8. The ejection elements 5 and 6 can therefore not be pivoted further.

Gleichzeitig wurde auch das Ladeelement 13 maximal verschwenkt, und zwar so weit, dass es am Türflügel 4 zum Anliegen kommt. Diese Stellung der Ausstoßvorrichtung 1 markiert somit auch den Beginn des Ladevorgangs.At the same time, the loading element 13 was swiveled to the maximum, to the extent that it comes to rest on the door leaf 4. This position of the ejection device 1 thus also marks the start of the charging process.

Und zwar beginnt ein Benutzer nun damit die Falt-Schiebe-Tür 2 weiter zu öffnen, was gleichzeitig zu einem Verschieben des Türflügels 3 und einem Zusammenfalten der Türflügel 3 und 4, das heißt zu einer Reduktion des von den Türflügeln 3 und 4 eingeschlossenen Winkels, führt. Diese Kraftausübung durch den Benutzer ist in der Figur 6a) mittels eines Pfeils angedeutet.Namely, a user now begins to open the folding sliding door 2 further, which at the same time causes the door leaf 3 to move and the door leaves 3 and 4 to fold, that is to say a reduction in the angle enclosed by the door leaves 3 and 4, leads. This exertion of force by the user is in the Figure 6a ) indicated by an arrow.

Das Zusammenfalten der Falt-Schiebe-Tür 2 führt, da das Ladeelement 13 an dem Türflügel 4 anliegt, zu einem Verschwenken des Ladeelements 13 in Richtung seiner ursprünglichen Stellung, welche es in der Schließstellung der Falt-Schiebe-Tür 2 eingenommen hat (vgl. Figuren 6b) und 6c)). Die Schwenkbewegung des Ladeelements 13 wird über das Verbindungselement 41 in eine Linearbewegung des Linearschlittens 39 umgesetzt, wobei die Bewegung des Linearschlittens 39 wiederum durch die Synchronisierungsvorrichtung 18 in einer gegenläufigen Linearbewegung des Linearschlittens 34 resultiert, was in weiterer Folge zu einem Laden des Kraftspeichers 8 und zu einer gegensinnigen Schwenkbewegung der Ausstoßelemente 5 und 6 führt.The folding of the folding sliding door 2, since the loading element 13 rests on the door leaf 4, causes the loading element 13 to pivot in the direction of its original position, which it assumed when the folding sliding door 2 was in the closed position (cf. Figures 6b ) and 6c )). The pivoting movement of the loading element 13 is converted via the connecting element 41 into a linear movement of the linear slide 39, the movement of the linear slide 39 in turn resulting from the synchronization device 18 in an opposite linear movement of the linear slide 34, which subsequently leads to a loading of the force accumulator 8 and an opposite pivotal movement of the ejection elements 5 and 6 leads.

Figur 7 zeigt eine Stellung der Ausstoßvorrichtung 1 im Zuge des weiteren Zusammenfaltens der Falt-Schiebe-Tür. In diesem Zustand wird ausschließlich der Kraftspeicher 8 geladen. Figure 7 shows a position of the ejection device 1 in the course of the further folding of the folding sliding door. In this state, only the energy store 8 is loaded.

In weiterer Folge treffen die Ausstoßelemente 5 und 6 über die Rollen 51 und 52 auf die Schrägflächen 22 bzw. 23, wodurch zusätzlich auch noch der Kraftspeicher 9 geladen wird. Die Figuren 8a) bis 8c) stellen exemplarisch eine Zwischenstellung der Ausstoßvorrichtung 1 beim gleichzeitigen Laden der Kraftspeicher 8 und 9 dar.Subsequently, the ejection elements 5 and 6 meet the inclined surfaces 22 and 23 via the rollers 51 and 52, as a result of which the energy accumulator 9 is additionally loaded. The Figures 8a) to 8c ) represent an example of an intermediate position of the ejection device 1 while simultaneously loading the energy stores 8 and 9.

In allen bisher beschriebenen Stellungen der Ausstoßvorrichtung 1 ist der Angriffswinkel 26 des Kraftumlenkhebels 24, 25 an den Ausstoßelementen 5 und 6 fixiert (vgl. Figur 1c)). Figur 8c), welche einen Ausschnitt der in Figur 8b) dargestelltenIn all the positions of the ejection device 1 described so far, the angle of attack 26 of the power deflection lever 24, 25 is fixed to the ejection elements 5 and 6 (cf. Figure 1c )). Figure 8c ), which is a section of the Figure 8b ) shown

Ausstoßvorrichtung 1 mit aufgeschnittenem Ausstoßelement 5 zeigt, dient der Veranschaulichung dieser Fixierung des Angriffswinkels des Kraftumlenkhebels: Der Kraftumlenkhebel 24, 25 ist an dem Linearschlitten 56 (vgl. auch Figur 1e)) drehbar gelagert. Wenn der Angriffswinkel fixiert ist, wird eine Drehbewegung des plattenförmigen Bauteils 25 des Kraftumlenkhebels relativ zu dem Linearschlitten 56 bzw. zu den Ausstoßelementen 5 und 6 unterbunden. Hierzu ist ein Klinkenbolzen 55 vorgesehen, welcher in einer Ausnehmung der Basis 54 angeordnet ist und zur Fixierung des Angriffswinkels des Kraftumlenkhebels in eine am Linearschlitten 56 vorgesehene Ausnehmung eingreift. Dadurch wird eine Bewegung des Linearschlittens 56 in Richtung der freien Enden der Ausstoßelemente 5 und 6 unterbunden. In die entgegengesetzte Richtung kann sich der Linearschlitten 56 ohnehin nicht bewegen, da er sich in der in der Basis 54 vorgesehenen Führungsbahn 66 in einer Endstellung befindet. Der Linearschlitten 56 ist mit der Basis 54 über eine Zugfeder 57, die in dem in Figur 8c) gezeigten Zustand leicht vorgespannt ist, verbunden. Der Bolzen 55 kann bei fixiertem Angriffswinkel auch nicht in vertikaler Richtung entweichen und so den Linearschlitten 56 freigeben, da eine solche Bewegung des Bolzens 55 in vertikale Richtung durch eine Feststellvorrichtung 40, die über eine Druckfeder 58 kraftbeaufschlagt ist und ebenfalls in der Basis 54 verschiebbar gelagert ist, unterbunden ist. Insgesamt gesehen kann sich der Linearschlitten 56 relativ zur Basis 54 nicht bewegen. Somit ist der Angriffswinkel des plattenförmigen Teils 25 des Kraftumlenkhebels an den Ausstoßelementen 5 und 6 fixiert.Showing ejection device 1 with cut-out ejection element 5 serves to illustrate this fixing of the angle of attack of the power deflection lever: The power deflection lever 24, 25 is on the linear slide 56 (cf. also Figure 1e )) rotatably mounted. When the angle of attack is fixed, a rotational movement of the plate-shaped component 25 of the force deflection lever relative to the linear slide 56 or to the ejection elements 5 and 6 is prevented. For this purpose, a pawl pin 55 is provided, which is arranged in a recess in the base 54 and which engages in a recess provided on the linear slide 56 to fix the angle of attack of the force-deflection lever. This prevents movement of the linear slide 56 in the direction of the free ends of the ejection elements 5 and 6. The linear slide 56 cannot move in the opposite direction anyway, since it is in an end position in the guide track 66 provided in the base 54. The linear slide 56 is connected to the base 54 via a tension spring 57, which in the Figure 8c ) is slightly biased, connected. The bolt 55 cannot escape in the vertical direction when the angle of attack is fixed and thus release the linear slide 56, since such movement of the bolt 55 in the vertical direction by a locking device 40, which is acted upon by a compression spring 58 and is also displaceably mounted in the base 54 is prevented. Seen overall, the linear slide 56 cannot move relative to the base 54. Thus, the angle of attack of the plate-shaped part 25 of the power lever on the ejection elements 5 and 6 is fixed.

Möchte man die Falt-Schiebe-Tür 2 nun aber vollständig zusammenfalten, das heißt in eine Stellung überführen, in welcher die Türflügel 3 und 4 im Wesentlichen parallel zueinander ausgerichtet sind, so muss die Fixierung des Angriffswinkels des Kraftumlenkhebels 24, 25 aufgehoben werden (vgl. Figur 9a)). Die Aufhebung der Fixierung erfolgt dadurch, dass das Ladeelement 13 durch die Relativbewegung der Türflügel 3 und 4 der Falt-Schiebe-Tür 2 noch weiter in Richtung der Basis 29 der Ausstoßvorrichtung 1 bewegt wird. Dadurch wird die Feststellvorrichtung 40, welche an dem Linearschlitten 39, der über das Verbindungselement 41 mit dem Ladeelement 13 gekoppelt ist, von dem plattenförmigen Teil 25 des Kraftumlenkhebels wegbewegt (vgl. Figur 1e)). Das heißt, dass die Feststellvorrichtung 40 in der Basis 54 der Ausstoßelemente 5 und 6 derart bewegt wird, dass die Druckfeder 58 noch weiter komprimiert wird. Wie anhand von Figur 9b) erkennbar ist, wird dadurch in weiterer Folge der Bolzen 55 in vertikaler Richtung freigegeben. Wird nun Druck auf den Kraftumlenkhebel 24, 25 durch eine Relativbewegung der Türflügel 3 und 4 der Falt-Schiebe-Tür 2 ausgeübt, so führt dies zu einer Kraftbeaufschlagung des Linearschlittens 56, der den Bolzen 55 in vertikaler Richtung wegdrückt. Der Linearschlitten 56 kann sich in der Führungsbahn 66, die in der Basis 54 vorgesehen ist, in Richtung der freien Enden der Ausstoßelemente 5 und 6 bewegen und damit der Kraftumlenkhebel 24, 25 zusammengefaltet werden.However, if you now want to fold the folding and sliding door 2 completely, that is to say move it into a position in which the door leaves 3 and 4 are aligned essentially parallel to one another, then the fixing of the angle of attack of the power deflection lever 24, 25 must be removed (cf. . Figure 9a )). The fixation is canceled in that the loading element 13 is moved even further in the direction of the base 29 of the ejection device 1 by the relative movement of the door leaves 3 and 4 of the folding-sliding door 2. As a result, the locking device 40, which the linear slide 39, which is coupled to the loading element 13 via the connecting element 41, is moved away from the plate-shaped part 25 of the force deflection lever (cf. Figure 1e )). That is, the locking device 40 is moved in the base 54 of the ejection elements 5 and 6 in such a way that the compression spring 58 is compressed even further. As with Figure 9b ) can be seen, the bolt 55 is subsequently released in the vertical direction. If pressure is now exerted on the power deflecting lever 24, 25 by a relative movement of the door leaves 3 and 4 of the folding-sliding door 2, this leads to a force application to the linear slide 56, which pushes the bolt 55 away in the vertical direction. The linear slide 56 can move in the guideway 66, which is provided in the base 54, in the direction of the free ends of the ejection elements 5 and 6 and the force deflection lever 24, 25 can thus be folded up.

Es sei noch drauf hingewiesen, dass beim Erreichen der Stellung der Ausstoßvorrichtung 1, die in den Figuren 9a) bis 9c) dargestellt ist, der Ladevorgang der Kraftspeicher 8 und 9 abgeschlossen ist. Um ein in diesem Zustand ungewolltes Entladen zu verhindern, werden die Ausstoßelemente 5 und 6 mittels der Verriegelungsvorrichtungen 10 und 11 verriegelt.It should also be noted that when the ejector 1 reaches the position shown in FIGS Figures 9a) to 9c ) is shown, the charging process of the energy stores 8 and 9 is completed. In order to prevent unintentional unloading in this state, the ejection elements 5 and 6 are locked by means of the locking devices 10 and 11.

Da auch der Kraftspeicher 8 geladen ist, das Ladeelement 13 jedoch noch - genauso wie der Kraftumlenkhebel 24, 25 - auf die Basis 29 geklappt werden muss, um die Parallelstellung der Türflügel 3 und 4 erreichen zu können (vgl. Figur 10a) bis 10c)) und das Ladeelement 13 über den Linearschlitten 39 mit dem Linearschlitten 38 über die Synchronisierungsvorrichtung 18 bewegungsgekoppelt ist, bietet es sich an, den Ladezustand des Kraftspeichers 8 zu konservieren und ein im Wesentlichen kraftloses Zusammenklappen des Kraftumlenkhebels 24, 25 sowie des Ladeelements 13 zu ermöglichen. Das wird dadurch ermöglicht, dass die Kopplung der Linearschlitten 34 und 38 über die Sperrklinke 36, die am Linearschlitten 34 schwenkbar gelagert ist und im gekoppelten Zustand in eine Öffnung 67 des Linearschlittens 38 eingreift, aufgehoben wird, indem die Sperrklinke 36 von dem Linearschlitten 38 wegschwenkt. Dabei wird gleichzeitig der Linearschlitten 34 bei geladenem Kraftspeicher 8 an der Basis 29 festgelegt (vgl. Figur 9c)). Durch die Entkopplung der Linearschlitten 34 und 38 kann sich nun bei einer Bewegung des Linearschlittens 39, der mit dem Ladeelement 13 gekoppelt ist, der Linearschlitten 38 im Wesentlichen kraftlos mitbewegen.Since the energy accumulator 8 is also loaded, however, the loading element 13 still has to be folded onto the base 29, just like the force deflection lever 24, 25, in order to be able to achieve the parallel position of the door leaves 3 and 4 (cf. Figure 10a) to 10c )) and the charging element 13 is motionally coupled via the linear slide 39 to the linear slide 38 via the synchronization device 18, it is advisable to preserve the state of charge of the energy accumulator 8 and to enable the force-deflecting lever 24, 25 and the charging element 13 to be folded essentially without force . This is made possible by the fact that the coupling of the linear carriages 34 and 38 via the pawl 36, which is pivotally mounted on the linear carriage 34 and engages in the coupling state in an opening 67 of the linear carriage 38, is canceled by the pawl 36 pivoting away from the linear carriage 38 . At the same time, the linear slide 34 is fixed to the base 29 when the energy store 8 is loaded (cf. Figure 9c )). By decoupling the linear slide 34 and 38 can now with a movement of the linear slide 39, the Charging element 13 is coupled, the linear slide 38 move substantially without force.

Die Figur 10a) zeigt die Falt-Schiebe-Tür 2 im vollständig zusammengefalteten Zustand, in welchem die beiden Türflügel 3 und 4 im Wesentlichen parallel zueinander ausgerichtet sind. Die Figuren 10b) und 10c) zeigen den Zustand, welchen die Ausstoßvorrichtung 1 in dieser Stellung der Falt-Schiebe-Tür 2 einnimmt. Und zwar sind in diesem Zustand alle Elemente der Ausstoßvorrichtung 1 im Wesentlichen in der Ebene der Basis 29 angeordnet. Die Figur 10c) zeigt einen Ausschnitt der Ausstoßvorrichtung 1 mit aufgeschnittenem Ausstoßelement 5. Der Linearschlitten 56 befindet sich in der Führungsbahn 66 (vgl. z.B. Figur 8c)) in der dem freien Ende der Ausstoßelemente 5 und 6 benachbart angeordneten Endstellungen. Die Zugfeder 57 ist vollständig geladen.The Figure 10a ) shows the folding and sliding door 2 in the fully folded state, in which the two door leaves 3 and 4 are aligned essentially parallel to one another. The Figures 10b ) and 10c ) show the state which the ejection device 1 assumes in this position of the folding-sliding door 2. In this state, all elements of the ejection device 1 are arranged essentially in the plane of the base 29. The Figure 10c ) shows a section of the ejection device 1 with the ejection element 5 cut open. The linear slide 56 is located in the guideway 66 (cf. for example FIG Figure 8c )) in the end positions arranged adjacent to the free end of the ejection elements 5 and 6. The tension spring 57 is fully loaded.

Wie die Figuren 11a) und 11b) sowie 12a) und 12b) zeigen, kann die zusammengefaltete Falt-Schiebe-Tür 2 nun in einen am bzw. im Möbelkorpus 16 angeordneten Hohlraum 28 angeordnet werden. Dazu ist im oder am Hohlraum 28 eine Führungsvorrichtung 46 für die Falt-Schiebe-Tür 2 vorgesehen. Nun ist das Innere des Möbels 27 frei zugänglich. Im Inneren kann z.B. eine Küche 68 vorgesehen sein.As the Figures 11a) and 11b ) and 12a) and 12b), the folded folding-sliding door 2 can now be arranged in a cavity 28 arranged on or in the furniture body 16. For this purpose, a guide device 46 for the folding-sliding door 2 is provided in or on the cavity 28. Now the interior of the furniture 27 is freely accessible. A kitchen 68 can be provided inside, for example.

Um die Falt-Schiebe-Tür 2 ausgehend von dem in den Figuren 12a) und 12b) dargestellten Zustand wieder in die in der Figur 1a) dargestellte Schließstellung zu überführen, wird die zusammengefaltete Falt-Schiebe-Tür 2 wieder aus dem Hohlraum 28 herausbefördert. Beim Entfalten der Falt-Schiebe-Tür 2 entfaltet sich der Kraftumlenkhebel 24 und 25 unter Freiwerdung der in der Zugfeder 57 gespeicherten Energie. Auch das Ladeelement 13 schwenkt wieder von der Basis 29 weg. Hierzu sind zwei Schenkelfedern 42 vorgesehen (vgl. Figur 1e)), die das Ladeelement 13 in der z.B. in Figur 1d) gezeigten Neutralstellung halten. Beim vollständigen Zusammenfalten der Falt-Schiebe-Tür 2 wird Energie in den Schenkelfedern 42 deponiert, die beim Entfalten der Falt-Schiebe-Tür 2 wieder frei wird. Der Linearschlitten 56 wird wieder verriegelt und damit der Angriffswinkel des Kraftumlenkhebels 24, 25 an den Ausstoßelementen 5 und 6 fixiert (vgl. Figur 13b)). Weiterhin werden die beiden Linearschlitten 34 und 38 mittels der Sperrklinke 36 wieder miteinander verbunden (vgl. Figur 13c)). Insgesamt gesehen befindet sich die Ausstoßeinheit 1 nun wieder in ihrer Ausgangsstellung (vgl. Figuren 1c) und 1d)) und verbleibt dort bis zum erneuten Auslösen.To the folding sliding door 2 starting from the in the Figures 12a) and 12b ) shown again in the state in the Figure 1a ) to transfer the closed position shown, the folded folding sliding door 2 is conveyed out of the cavity 28 again. When the folding-sliding door 2 is unfolded, the force deflection lever 24 and 25 unfolds, releasing the energy stored in the tension spring 57. The loading element 13 also swings away from the base 29 again. For this purpose, two leg springs 42 are provided (cf. Figure 1e )), which the charging element 13 in the example in Figure 1d ) shown neutral position. When the folding-sliding door 2 is completely folded, energy is deposited in the leg springs 42, which is released again when the folding-sliding door 2 is unfolded. The linear slide 56 is locked again and thus the angle of attack of the power lever 24, 25 is fixed to the ejection elements 5 and 6 (cf. Figure 13b )). Furthermore, the two linear slides 34 and 38 are reconnected by means of the pawl 36 (cf. Figure 13c )). Overall, the ejection unit 1 is now in its starting position again (cf. Figures 1c) and 1d )) and remains there until triggered again.

Figur 14 zeigt eine Zwischenstellung der Falt-Schiebe-Tür 2 beim Überführen der Falt-Schiebe-Tür 2 aus dem in den Figuren 12a) und 12b) dargestellten Zustand in den in der Figur 1a) dargestellten Schließzustand durch Druckausübung durch einen Benutzer. Figure 14 shows an intermediate position of the folding sliding door 2 when transferring the folding sliding door 2 from the in the Figures 12a) and 12b ) shown in the state in the Figure 1a ) shown closed state by pressure exerted by a user.
