Description

Die Erfindung betrifft eine Schwingflügeltüre für einen Personendurchgang, mit einem ortsfesten Stützrohr, mit einem am Stützrohr gelagerten, nach beide Richtungen frei ausschwenkbaren Türflügel und mit einer Rückführeinrichtung, die mit dem Türflügel und mit am Stützrohr angeordneten, den Schwenkbereich des Türflügels bestimmenden Anschlägen in Wirkverbindung steht, wobei die Rückführeinrichtung dazu bestimmt ist, den ausgeschwenkten Türflügel von selbst in seine den Personendurchgang verschließende Ausgangslage zurückzuschwenken.The invention relates to a swinging wing door for a passage of people, with a stationary support tube, with a door wing mounted on the support tube and freely pivotable in both directions and with a feedback device which is in operative connection with the door wing and with the support tube arranged and determining the pivoting range of the door wing , wherein the feedback device is intended to pivot the swung-out door leaf back into its starting position which closes the passage of people.

Die deutsche Gebrauchsmusterschrift G 78 12 787 beschreibt eine derartige Schwingflügeltüre. Die Rückführeinrichtung wird bei dieser Türe durch zwei im Stützrohr angeordnete, gegenläufig wirkende Türschließer gebildet. Ein erster Nachteil dieser Schwingflügeltüre besteht darin, daß die in den Türschließern befindlichen Drehfedern den auftretenden Langzeitbelastungen nicht standhalten und frühzeitig brechen. Dies ist insofern verständlich, da Türschließer gewöhnlich bei Türen der üblichen Art Verwendung finden. Solche Türen sind nicht so häufigen Öffnungs- und Schließvorgängen unterworfen wie Schwingflügeltüren der eingangs genannten Art, die bevorzugt in SB-Geschäften zur Lenkung von Besucherströmen eingesetzt werden. Ein weiterer Nachteil der zum Stand der Technik zählenden Schwingflügeltüre besteht darin, daß das Stützrohr im Bereich der beiden Türschließer mindestens bis zur Hälfte des Rohrquerschnittes aufgeschnitten werden muß, damit die Schwenkhebel der beiden Türschließer über den Querschnitt des Stützrohres hinaus das Schwenkrohr des Türflügels erreichen. Der große Einschnitt bedeutet eine enorme Schwächung des Stützrohres.The German utility model G 78 12 787 describes such a swing door. The return device is formed in this door by two oppositely acting door closers arranged in the support tube. A first disadvantage of this swing door is that the torsion springs in the door closers do not withstand the long-term loads that occur and break prematurely. This is understandable because door closers are usually used for doors of the usual type. Such doors are not subject to opening and closing as often as swing doors of the type mentioned at the outset, which are preferably used in self-service shops to direct the flow of visitors. Another disadvantage of the swing door that belongs to the prior art is that the support tube in the area of the two door closers must be cut open at least up to half the tube cross-section so that the pivot levers of the two door closers reach the pivot tube of the door wing beyond the cross section of the support tube. The large incision means an enormous weakening of the support tube.

Die Aufgabe der Erfindung besteht darin, eine Schwingflügeltüre der gattungsgemäßen Art so weiterzuentwickeln, daß die eben geschilderten Nachteile vermieden werden.The object of the invention is to develop a swing door of the generic type so that the disadvantages just described are avoided.

Die Erfindung schlägt vor, als Antriebselement für die Rückführeinrichtung eine Drehfeder zu verwenden, die so vorgespannt ist, daß sie sowohl den Türflügel in seiner Ausgangslage hält, als auch imstande ist, die Schwenkbewegungen des Türflügels in beide Richtungen mit auszuführen und daß im Stützrohr eine das Schwingverhalten des Türflügels beeinflussende Dämpfungseinrichtung vorgesehen ist.The invention proposes to use a torsion spring as the drive element for the return device, which is biased so that it both holds the door leaf in its initial position, and is able to carry out the pivoting movements of the door leaf in both directions and that in the support tube one Vibration behavior of the door leaf influencing damping device is provided.

Durch die Wahl einer Drehfeder als Antriebselement für die Rückführeinrichtung ist es möglich, die Drehfeder außerhalb des Stützrohres anzuordnen. Die Drehfeder wird vom Stützrohr durchdrungen. Somit entfällt in zweckmäßiger Weise jener Einschnitt, der bisher zu einer Schwächung des Stützrohres führte. Da wiederum der Innendurchmesser der Drehfeder größer ist, als der Außendurchmesser des Stützrohres, läßt sich eine große und stabile Drehfeder verwenden, die wesentlich höhere Belastungen und häufigere Lastwechsel schadlos ertragen kann, als die Drehfedern der Türschließer der eingangs beschriebenen Schwingflügeltüre. Auch dies ist ein entscheidender Vorteil. Da durch den Wegfall der Türschließer, die bisher dämpfend auf die Schwingbewegungen des Türflügels einwirkten, ein lästiges Nachschwingen des Türflügels der erfindungsgemäßen Schwingflügeltüre zu erwarten wäre, schlägt die Erfindung in ebenfalls zweckmäßiger Weise vor, eine Einrichtung in der bevorzugten Form eines hydraulisch wirkenden Dämpfers vorzusehen, der dämpfend oder auch hemmend auf das Schwingverhalten des Türflügels so einwirkt, daß ein Nachschwingen oder ein Auspendeln eines in die Ausgangslage zurückkehrenden Türflügels ganz oder zumindest größtenteils vermieden wird. Diese Dämpfungseinrichtung ist in vorteilhafter und in nicht störender Weise innerhalb des Stützrohres untergebracht, wobei die Verbindung zum Türflügel durch eine Art Rollgetriebe hergestellt ist, das lediglich drei kleine Öffnungen im Stützrohr entstehen läßt, die nur eine unwesentliche Schwächung des Stützrohres bedeuten.By choosing a torsion spring as the drive element for the feedback device, it is possible to arrange the torsion spring outside the support tube. The torsion spring is penetrated by the support tube. It is therefore expedient to dispense with the incision that has previously weakened the support tube. Since again the inside diameter of the torsion spring is larger than the outside diameter of the support tube, a large and stable torsion spring can be used which can withstand much higher loads and more frequent load changes without damage than the torsion springs of the door closers of the swing door described at the beginning. This is also a crucial advantage. Since the elimination of the door closers, which previously had a dampening effect on the swinging movements of the door leaf, would result in annoying re-swinging of the door leaf of the swing door according to the invention, the invention also proposes in an expedient manner to provide a device in the preferred form of a hydraulically acting damper, which has a damping or inhibiting effect on the swinging behavior of the door leaf in such a way that a swinging or swinging of a door leaf returning to the starting position is completely or at least largely avoided. This damping device is housed in an advantageous and non-disruptive manner within the support tube, the connection to the door leaf being made by a type of roller gear that only creates three small openings in the support tube, which mean only an insignificant weakening of the support tube.

Es soll an dieser Stelle nicht unerwähnt bleiben, daß in der deutschen Gebrauchsmusterschrift G 79 25 911 eine Pendeltüre für Kundenführungsanlagen in SB-Geschäften beschrieben ist, die ebenfalls eine Drehfeder als Antriebselement für die Rückführeinrichtung verwendet. Diese Türe unterscheidet sich jedoch von der erfindungsgemäßen Schwingflügeltüre dadurch, daß sie entweder als eine rechts- oder als eine linksöffnende Pendeltüre konzipiert ist, bei welcher der Schwenkbereich des Türflügels höchstens 90° beträgt. Solche Pendeltüren lassen sich somit nur in einer vorbestimmten Richtung öffnen. Will man diese Türen in der entgegengesetzten Richtung öffnen, muß eine sogenannte

Figure imgb0001
Paniksicherung" überwunden werden, was nur durch Aufbietung einer größeren Kraft möglich ist. Wird bei der genannten Pendeltüre der Türflügel im Panikfalle entgegengesetzt zur vorbestimmten Richtung gewaltsam ausgeschwenkt, so verbleibt der Türflügel in dieser Position. Die Rückführeinrichtung dieser Türe ist nicht in der Lage, den Türflügel in seine den Personendurchgang verschließende Ausgangslage zurückzuholen. Die in der erwähnten Gebrauchsmusterschrift beschriebene Pendeltüre ist daher als gattungsfremd einzustufen.It should be mentioned at this point that in the German utility model G 79 25 911 a swing door for customer guidance systems in self-service shops is described, which also uses a torsion spring as a drive element for the return device. However, this door differs from the swing door according to the invention in that it is designed either as a right-hand or as a left-opening swing door, in which the pivoting range of the door wing is at most 90 °. Such swing doors can thus only be opened in a predetermined direction. If you want to open these doors in the opposite direction, a so-called
Figure imgb0001
Panic protection "can be overcome, which is only possible by exerting a greater force. If, in the event of panic, the door wing in the case of panic is violently swung out in the opposite direction to the predetermined direction, the door wing remains in this position. The return device of this door is unable to The swing door described in the utility model mentioned is therefore to be classified as foreign to the genre.

Die Erfindung wird anhand eines Ausführungsbeispieles näher erläutert. Es zeigt

The invention is explained in more detail using an exemplary embodiment. It shows

individual components that are important for the function of the swing door.

Bei der in Fig. 1 im Schnitt dargestellten Schwingflügeltüre 1 ist als zentrales Bauteil ein Stützrohr 2 zu betrachten, das in bekannter Weise entweder über eine Fußplatte 4 am Boden anschraubbar oder mittels zweier nicht dargestellter Flanschplatten an einer Wand befestigbar ist. Am Stützrohr 2 ist ein nach beiden Richtungen frei ausschwenkbarer Türflügel 5 angeordnet, der üblicherweise aus einem Schwenkrohr 6 mit daran befestigtem Bügel 7 besteht. Bin unteres und ein oberes Lager 8, 9, die am Stützrohr 2 angeordnet sind, ermöglichen es in bekannter Weise, daß der Türflügel 5 um die Längsachse 3 des Stützrohres 2 verschwenkt werden kann. In der Zeichnung ist der Türflügel 5 um 90° versetzt dargestellt. Die Schwenkachse des Türflügels 5 und die Längsachse 3 des Stützrohres 2 sind somit identisch. Im unteren Bereich des Stützrohres 2, knapp unterhalb des Türflügels 5, ist im Stützrohr 2 eine hydraulisch wirkende Dämpfungseinrichtung 10 ortsfest angeordnet. Die Dämpfungseinrichtung 10, die durchaus auch knapp oberhalb des Türflügels 5 im Stützrohr 2 angeordnet sein kann, weist ein zylindrisches Gehäuse 11 auf, das eine nach oben ragende Welle 12 trägt. Durch im Gehäuse 11 befindliches Hydrauliköl und durch weitere, nicht näher bezeichnete, im Gehäuse 11 befindliche Mittel, läßt sich die Welle 12 der Dämpfungseinrichtung 10 relativ schwer drehen. Die Welle 12 greift zentrisch in ein sogenanntes Rollgetriebe 13 ein, das zwei zylindrische Schalen 14 aufweist, die eine ringförmige Bahn bilden, aufwelcher wenigstens drei Kugeln 15 abrollen. Die Kugeln 15 sind in drei horizontalen Öffnungen 16 geführt, die sich in der Wand des Stützrohres 2 befinden. Die Kugeln 15 ragen über den Grundriß des Stützrohres 2 hinaus und rollen an einer unteren Anschlaghülse 21 ab, die ortsfest mit dem Schwenkrohr 6 des Türflügels 5 verbunden ist. Die weitere Funktion der unteren Anschlaghülse 21 wird später beschrieben. Die Schalen 14 des Rollgetriebes 13 werden durch Federkraft gegeneinander gepreßt, wobei die Welle 12 der Dämpfungseinrichtung 10 drehschlüssig mit einer Buchse 17 verbunden ist, die ihrerseits wieder an der unteren der beiden Schalen 14 befestigt ist. Das Rollgetriebe 13 erschwert das Verschwenken des Türflügels 5. Ein Nachschlagen oder Nachschwingen des verschwenkten, in die Ausgangslage zurückkehrenden Türflügels 5 wird dadurch verhindert. Die Schwingflügeltüre 1 ist mit einer Rückführeinrichtung 20 ausgestattet, welche den ausgeschwenkten Türflügel 5 automatisch in die Ausgangslage zurückbewegt. Die Rückführeinrichtung 20 weist eine untere und eine obere Anschlaghülse 21, 22, eine untere und obere Kulissenhülse 24, 25, eine Drehfeder 30 und Anschläge 29 auf, wobei letztere ortsfest am Stützrohr 2 angeordnet sind. Der Innendurchmesser des Schwenkrohres 6 ist größer als der Außendurchmesser des Stützrohres 2, so daß ein zylindrischer Raum 28 gebildet ist, in welchem sich die Anschlaghülsen 21, 22, die Kulissenhülsen 24, 25 und die Drehfeder 30 befinden. Das Stützrohr 2 durchdringt somit die Anschlaghülsen 21, 22, die Kulissenhülsen 24, 25 und die Drehfeder 30. Die Anschläge 29 sind durch starke Stifte gebildet, welche das Stützrohr 2 in einem Abstand horizontal und parallel zueinander zentrisch so durchdringen, daß sie über den Grundriß des Stützrohres 2 überstehen. Die Überstände bilden Anschlagstellen für die Kulissenhülsen 24, 25. Die eben erwähnten Bauteile sind so angeordnet, daß auf die untere Anschlaghülse 21 die untere Kulissenhülse 24 folgt, anschließend durch die Drehfeder 30 getrennt, sich die obere Kulissenhülse 25 anschließt und über der oberen Kulissenhülse 25 die obere Anschlaghülse 22 vorgesehen ist. Das obere Ende 32 der Drehfeder 30 ist ortsfest mit der oberen Kulissenhülse 25 und das untere Ende 31 der Drehfeder 30 ist ortsfest mit der unteren Kulissenhülse 24 verbunden. Zusammen mit Fig. 2 läßt sich der Aufbau und die Funktion der Rückführeinrichtung 20 näher erläutern. Die in Fig. 2 anhand einer Explosionszeichnung dargestellten Bauteile sind der Ausgangslage des Türflügels 5 entsprechend dargestellt. Die untere Anschlaghülse 21 liegt am unteren Lager 8 und die obere Anschlaghülse 22 grenzt an das obere Lager 9 an. Die Anschlaghülse 21, 22 sind mit dem Schwenkrohr 6 des Türflügels 5 ortsfest verbunden und gegenüber dem Stützrohr 2 drehbar angeordnet, damit sich der Türflügel 5 verschwenken läßt. An den Anschlaghülsen 21, 22 befinden sich Einfräsungen derart, daß vier vertikale Anschlagflächen 23 gebildet sind. Gleiche Anschlagflächen 23 befinden sich auch an den Kulissenhülsen 24, 25, die zwischen den Anschlaghülsen 21, 22 angeordnet sind und in diese so eingreifen, daß jeweils zwei Anschlagflächen 23 der Anschlaghülsen 21, 22 und der Kulissenhülsen 24, 25 dann aneinander anliegen, wenn sich der Türflügel 5 entweder in seiner Ausgangslage oder in seiner maximal ausgeschwenkten Lage befindet. Die ebenfalls gegenüber dem Stützrohr 2 drehbar gelagerten Kulissenhülsen 24, 25 weisen an ihrem zylindrischen Mantel zwei sich gegenüberliegende kulissenbahnartige Durchbrüche 26 auf, in welche die Anschläge 29 mit ihren Enden ragen. Die Durchbrüche 26 liegen mit je einem Ende 27 an den Anschlägen 29 dann an, wenn sich der Türflügel 5 in der Ausgangslage oder in einer maximal ausgeschwenkten Lage befindet. Die Anschläge 29 bestimmen zusammen mit den Kulissenhülsen 24, 25 und den Anschlaghülsen 21, 22 den Schwenkbereich des Türflügels 5. Zwischen den Kulissenhülsen 24, 25 ist die Drehfeder 30 angeordnet, deren oberes Ende 32 mit der oberen Kulissenhülse 25 und deren unteres Ende 31 mit der unteren Kulissenhülse 24 ortsfest verbunden ist. In Zusammenwirken mit den Anschlägen 29 sind die Kulissenhülsen 24, 25 so angeordnet, daß in Ausgangslage des Türflügels 5 die Drehfeder 30 vorgespannt ist. Dies bewirkt, daß die Kulissenhülsen 24, 25 in Ausgangslage des Türflügels 5 gegenläufig gegen die Anschläge 29 gedrückt werden. Um den Türflügel 5 aus seiner Ausgangslage heraus zu verschwenken, muß deshalb eine gewisse, allerdings von Hand leicht aufzubringende Kraft auf den Türflügel 5 ausgeübt werden. Die Lage der Anschläge 29, die Länge der kulissenartigen Durchbrüche 26 sowie die Positionen der Anschlagflächen 23 sind nun z.B. so angeordnet, daß bei einem Verschwenken des Türflügels 5 in der Zeichnung nach links (oberer Pfeil), zwei Anschlagflächen 23 der unteren Anschlaghülse 21 gegen zwei Anschlagflächen 23 der unteren Kulissenhülse 24 drücken und diese ebenfalls zur gleichen Drehung veranlassen. Der Türflügel 5 kann so weit gedreht werden -gewöhnlich sind dies etwa 90°- bis die bis dahin freien Enden 27 der Durchbrüche 26 der unteren Anschlaghülse 21 an den Anschlägen 29 anliegen. Bei diesem Drehvorgang hat sich die obere Kulissenhülse 25 nicht mitbewegt, da deren Durchmesser 26 gegenläufig zu den Durchbrüchen 26 der unteren Kulissenhülse 24 angeordnet sind. Allerdings hat sich durch die ortsfeste Verbindung mit dem Türflügel 5 die obere Anschlaghülse 22 mitgedreht. Dieses Mitdrehen ist trotz der feststehenden oberen Kulissenhülse 25 möglich, weil die Anschlagflächen 23 der oberen Anschlaghülse 22 und der oberen Kulissenhülse 25 einerseits und die Anschlagflächen 23 der unteren Anschlaghülse 21 und der unteren Kulissenhülse 24 andererseits ebenfalls gegenläufig angeordnet sind. Durch die gegenläufigen Anordnungen der Anschlagflächen 23 und der Durchbrüche 26 werden freie Räume geschaffen, die es ermöglichen, daß bei einem Ausschwenken des Türflügels 5 in eine der beiden Richtungen beispielsweise die untere und die obere Anschlaghülse 21, 22 sowie die untere Kulissenhülse 24 und beim Verschwenken des Türflügels 5 in die andere Richtung wiederum die untere und obere Anschlaghülse 21, 22 nunmehr jedoch die obere Kulissenhülse 25 mitgedreht werden, während im zuletzt genannten Fall die untere Kulissenhülse 24 feststeht. Letzteres ist im Beispiel dann gegeben, wenn der Türflügel 5 in die Zeichenebene (unterer Pfeil) geschwenkt wird. Bei jedem aus der Ausgangslage beginnenden Schwenkvorgang des Türflügels 5 wird die Drehfeder 30 noch weiter vorgespannt. Die als Antriebselement vorgesehene Drehfeder 30 ist somit ein Kraftspeicher, der mit der gespeicherten Kraft den ausgeschwenkten Türflügel 5 wieder in seine Ausgangslage bewegt.In the swing wing door 1 shown in section in FIG. 1, a support tube 2 is to be considered as the central component, which can be screwed onto the floor in a known manner either via a base plate 4 or fastened to a wall by means of two flange plates (not shown). Arranged on the support tube 2 is a door leaf 5 which can be freely pivoted in both directions and which usually consists of a pivot tube 6 with a fastener attached to it Bracket 7 is made. Bin lower and an upper bearing 8, 9, which are arranged on the support tube 2, allow in a known manner that the door leaf 5 can be pivoted about the longitudinal axis 3 of the support tube 2. In the drawing, the door leaf 5 is shown offset by 90 °. The pivot axis of the door leaf 5 and the longitudinal axis 3 of the support tube 2 are thus identical. In the lower region of the support tube 2, just below the door leaf 5, a hydraulically acting damping device 10 is arranged in a fixed manner in the support tube 2. The damping device 10, which can also be arranged just above the door leaf 5 in the support tube 2, has a cylindrical housing 11 which carries an upwardly projecting shaft 12. By means of hydraulic oil in the housing 11 and by further means (not described in more detail) in the housing 11, the shaft 12 of the damping device 10 is relatively difficult to rotate. The shaft 12 engages centrally in a so-called roller gear 13 which has two cylindrical shells 14 which form an annular path on which at least three balls 15 roll. The balls 15 are guided in three horizontal openings 16, which are located in the wall of the support tube 2. The balls 15 protrude beyond the outline of the support tube 2 and roll on a lower stop sleeve 21 which is fixedly connected to the pivot tube 6 of the door leaf 5. The further function of the lower stop sleeve 21 will be described later. The shells 14 of the roller drive 13 are pressed against one another by spring force, the shaft 12 of the damping device 10 being connected in a rotationally locking manner to a bushing 17 which in turn is fastened to the lower of the two shells 14. The roller gear 13 makes it more difficult to pivot the door leaf 5. This prevents the pivoted door leaf 5 from looking up or swinging again. The swing door 1 is equipped with a feedback device 20 which automatically moves the swung out door leaf 5 back to the starting position. The feedback device 20 has a lower and an upper stop sleeve 21, 22, a lower and an upper link sleeve 24, 25, one Torsion spring 30 and stops 29, the latter being arranged in a stationary manner on the support tube 2. The inner diameter of the swivel tube 6 is larger than the outer diameter of the support tube 2, so that a cylindrical space 28 is formed in which the stop sleeves 21, 22, the link sleeves 24, 25 and the torsion spring 30 are located. The support tube 2 thus penetrates the stop sleeves 21, 22, the link sleeves 24, 25 and the torsion spring 30. The stops 29 are formed by strong pins which penetrate the support tube 2 at a distance horizontally and parallel to each other so that they center over the floor plan protrude from the support tube 2. The protrusions form stop points for the link sleeves 24, 25. The components just mentioned are arranged so that the lower link sleeve 24 is followed by the lower link sleeve 24, then separated by the torsion spring 30, the upper link sleeve 25 connects and over the upper link sleeve 25 the upper stop sleeve 22 is provided. The upper end 32 of the torsion spring 30 is fixedly connected to the upper link sleeve 25 and the lower end 31 of the torsion spring 30 is fixedly connected to the lower link sleeve 24. Together with FIG. 2, the structure and the function of the feedback device 20 can be explained in more detail. The components shown in FIG. 2 on the basis of an exploded drawing are shown corresponding to the starting position of the door leaf 5. The lower stop sleeve 21 lies on the lower bearing 8 and the upper stop sleeve 22 abuts the upper bearing 9. The stop sleeves 21, 22 are fixedly connected to the swivel tube 6 of the door leaf 5 and rotatably arranged relative to the support tube 2 so that the door leaf 5 can be pivoted. There are millings on the stop sleeves 21, 22 in such a way that four vertical stop surfaces 23 are formed. The same stop surfaces 23 are also located on the link sleeves 24, 25, which are arranged between the stop sleeves 21, 22 and engage in such that two stop surfaces 23 of the stop sleeves 21, 22 and the link sleeves 24, 25 abut each other when the door leaf 5 either in its initial position or in its maximum swung out Location. The guide sleeves 24, 25, which are also rotatably mounted with respect to the support tube 2, have on their cylindrical jacket two opposite guide track-like openings 26, into which the stops 29 project with their ends. The openings 26 each have an end 27 on the stops 29 when the door leaf 5 is in the starting position or in a maximum pivoted position. The stops 29 together with the link sleeves 24, 25 and the stop sleeves 21, 22 determine the pivoting range of the door leaf 5. Between the link sleeves 24, 25, the torsion spring 30 is arranged, the upper end 32 with the upper link sleeve 25 and the lower end 31 thereof the lower link sleeve 24 is fixedly connected. In cooperation with the stops 29, the link sleeves 24, 25 are arranged so that the torsion spring 30 is biased in the initial position of the door leaf 5. This causes the link sleeves 24, 25 to be pressed against the stops 29 in opposite directions in the starting position of the door leaf 5. In order to pivot the door leaf 5 out of its initial position, a certain force, which is, however, easy to apply by hand, must therefore be exerted on the door leaf 5. The position of the stops 29, the length of the slot-like openings 26 and the positions of the stop surfaces 23 are now arranged, for example, so that when the door leaf 5 is pivoted to the left in the drawing (upper arrow), two stop surfaces 23 of the lower stop sleeve 21 against two Press stop surfaces 23 of the lower link sleeve 24 and also cause the same to rotate. The door leaf 5 can be turned so far - usually this is about 90 ° - until the ends 27 of the openings 26 of the lower stop sleeve 21, which are free until then, bear against the stops 29. During this turning process, the upper link sleeve 25 did not move because its diameter 26 is arranged in the opposite direction to the openings 26 of the lower link sleeve 24. However, the upper stop sleeve 22 has also rotated due to the fixed connection to the door leaf 5. This turning is despite the fixed upper link sleeve 25 possible because the stop surfaces 23 of the upper stop sleeve 22 and the upper link sleeve 25 on the one hand and the stop surfaces 23 of the lower stop sleeve 21 and the lower link sleeve 24 are also arranged in opposite directions. Due to the opposing arrangements of the stop surfaces 23 and the openings 26, free spaces are created which make it possible, for example, for the lower and the upper stop sleeves 21, 22 and the lower link sleeve 24 and when pivoting when the door leaf 5 is pivoted out in one of the two directions of the door leaf 5 in the other direction in turn the lower and upper stop sleeves 21, 22 but now the upper link sleeve 25 are rotated, while in the latter case the lower link sleeve 24 is fixed. The latter is given in the example when the door leaf 5 is pivoted into the drawing plane (lower arrow). Each time the door leaf 5 pivots from the starting position, the torsion spring 30 is further biased. The torsion spring 30 provided as the drive element is thus an energy accumulator which, with the stored force, moves the swung-out door leaf 5 back into its starting position.
