Abstract

A closure sequence control device for a double-wing door comprising a standing wing 1 and a moving wing 2 is proposed. The door wings are each movable by a door closer 11, 21 acting in the closing direction and their closure sequence is controlled. In this arrangement, the door frame-side ends of the pivot arms 12, 22 of the door closers 11, 21 are displaceable by means of a respective sliding piece 14, 24 in a slideway 3 attached horizontally to the door frame. The moving wing-side sliding piece 24 can be fixed in the closing direction by means of a blocking device which is capable of being subjected to excess pressure in the event of an overload and is actuable by the standing wing 1 via an interposed control member 61, 62, 63 for the closure sequence control. In this arrangement, the control member is an axially fixed, rotatable, non-round bar, in particular a square bar, which is provided with an approximately centrically arranged transition piece 61 twisted by about 45 DEG and is received at one end 62 in a torsionally connected manner in the standing wing-side sliding piece 14 and which penetrates with the other end 63 through the moving wing-side sliding piece 24, in which is received the blocking device which is actuable via the rotation of the square bar to be brought about by the standing wing 1 for the closure sequence control upon displacement of the sliding piece 14. <IMAGE>

Description

Die Erfindung betrifft eine Schließfolgeregelvorrichtung nach dem Oberbegriff des Anspruches 1. Entsprechende zweiflügelige Türen überlappen einander in der Regel im Mittelbereich, so daß der eine einen Standflügel bildende Türflügel einen Anschlag für den anderen, den Gangflügel bildenden Türflügel aufweist. Um die Türflügel ordnungsgemäß zu schließen, ist eine Schließfolge notwendig, die sicherstellt, daß der geöffnete Standflügel dem Gangflügel vorläuft, d.h. der Standflügel vor dem Gangflügel geschlossen ist. Eine Schließfolgeregelvorrichtung nach dem Oberbegriff des Anspruches 1 ist aus der DE 36 04 091 A 1 bekannt, die eine Weiterentwicklung der Vorrichtung nach der DE 33 36 739 C 2 ist.The invention relates to a closing sequence control device according to the preamble of claim 1. Corresponding two-wing doors usually overlap each other in the central region, so that the door wing forming a fixed leaf has a stop for the other door leaf forming the active leaf. In order to properly close the door leaves, a closing sequence is necessary which ensures that the opened passive leaf leads the active leaf, i.e. the passive leaf in front of the active leaf is closed. A closing sequence control device according to the preamble of claim 1 is known from DE 36 04 091 A1, which is a further development of the device according to DE 33 36 739 C2.

Bei diesen bekannten zweiflügeligen Türen ist es mit Hilfe der Schließregelvorrichtung möglich, den Gangflügel bei geschlossenem Standflügel in jeder Stellung zu öffnen und zu verschließen.In these known double-leaf doors, it is possible with the aid of the closing control device to open and close the active leaf in any position when the passive leaf is closed.

Bei ganz oder teilweise geöffnetem Standflügel kann der Gangflügel in Öffnungsrichtung frei betätigt werden, bei Belastung des Gangflügels in Schließrichtung jedoch wirkt eine Sperrvorrichtung, die durch Betätigung über den Gangflügel kurz vor Erreichen seiner Schließlage gelöst wird und die Schließung des Gangflügels zuläßt. Es ist jedoch auch sichergestellt, daß bei geöffnetem Standflügel und Auftreten einer Überlast am Gangflügel dieser gegen die Sperrvorrichtung in Schließrichtung verschoben werden kann, um eine Zerstörung des Türschließers bzw. des zugehörigen Hebelgestänges infolge der auftretenden hohen Momente zu verhindern. Bei dieser aus der DE 36 04 091 A 1 bekannten Schließfolgeregelvorrichtung sind die beiden Türflügel von je einem im Schließsinn wirkenden Türschließer bewegbar. Die türrahmenseitigen Enden der zugehörigen Schwenkarme der Türschließer sind jeweils mit einem Gleitstück in einer am Türrahmen horizontal angebrachten Gleitführung verschiebbar. Das standflügelseitige Gleitstück wirkt in der Schließlage des Standflügels gegen einen in der Führungsschiene gelagerten Gleitriegel, über den durch eine als axial verschiebbare Klemmstange ausgebildetes Steuerglied ein Sperrglied feststellbar und freigebbar ist, welches die Gangflügelseite steuert. Zur Vermeidung von Beschädigungen bei am Gangflügel in dessen Schließrichtung wirkender Überlast ist eine als Sperrglied ausgebildete, eine den Gleitriegel bildende, längsverschiebbare Klemmstange umgreifende Klemmplatte einerseits an einem vom Standflügel in Freigabelage überführbaren Federlager und andererseits an einem auf der Klemmstange geführten Überlastglied federbelastet abgestützt, wobei das Überlastglied einerseits über ein bei Überlast nachgebendes Federglied an einem ortsfesten Anschlagglied gehaltert ist.When the passive leaf is fully or partially open, the active leaf can be freely actuated in the opening direction, but when the active leaf is loaded in the closing direction, a locking device acts which is released by actuating the active leaf shortly before reaching its closed position and allows the active leaf to be closed. However, it is also ensured that when the passive leaf is open and an overload occurs on the active leaf, it can be moved against the locking device in the closing direction in order to prevent destruction of the door closer or the associated lever linkage as a result of the high moments that occur. In this closing sequence control device known from DE 36 04 091 A 1, the two door leaves can each be moved by a door closer acting in the closing direction. The ends of the associated swivel arms of the door closers on the door frame side can each be displaced with a slide piece in a slide guide horizontally attached to the door frame. In the closed position of the passive leaf, the passive leaf-side slide acts against a slide bolt mounted in the guide rail, via which a locking member, which controls the active leaf side, can be ascertained and released by a control member designed as an axially displaceable clamping rod. In order to avoid damage in the event of an overload acting on the active leaf in its closing direction, a clamping plate designed as a locking member and encompassing the sliding bar, longitudinally displaceable clamping rod is supported spring-loaded on the one hand on a spring bearing which can be moved from the passive leaf into the release position and on the other hand on an overload member guided on the clamping rod Overload member is held on the one hand via a spring member yielding in the event of an overload on a stationary stop member.

Eine solche Schließfolgeregelung ist verhältnismäßig aufwendig. Die eingesetzte Klemmplatte wirkt durch Verkantung gegen die Klemmstangen, so daß es bei häufiger Beanspruchung zur Beschädigung der Klemmplatte oder der Klemmstange in der Art von sogenannten Rattermarken kommen kann.Such a closing sequence control is relatively complex. The clamping plate used acts by tilting against the clamping rods, so that it can damage the clamping plate or the clamping rod in case of frequent use the kind of so-called chatter marks can come.

Der Erfindung liegt die Aufgabe zugrunde, eine Schließfolgeregelvorrichtung für eine zweiflügelige Tür entsprechend dem Oberbegriff des Anspruches 1 zu vereinfachen und ihre Betriebssicherheit zu vergrößern.The invention has for its object to simplify a closing sequence control device for a two-leaf door according to the preamble of claim 1 and to increase its operational reliability.

Diese Aufgabe wird durch die kennzeichnenden Merkmale des Anspruches 1 gelöst. Die beiden Gleitstücke an den Enden der Schwenkarme der Türschließer werden direkt durch ein Steuerglied in der Form einer verdrehbaren Vierkantstange verbunden. Damit wird durch Verschieben des standflügelseitigen Gleitstückes im Bereich der Schließlage sowohl in Schließ- als auch in Öffnungsrichtung die Vierkantstange verdreht, die aufgrund der beiden Verdrehstellungen ihren wirksamen Durchmesser verändert gegenüber der im standflügelseitig angeordneten Sperrvorrichtung. Diese Sperrvorrichtung ist damit in besonders einfacher Weise in den entscheidenden Schließlagebereichen des Standflügels über die Drehmomentenkupplung am standflügelseitigen Gleitstück beaufschlagt. In der Schließlage des Standflügels hat das standflügelseitige Gleitstück das Übergangsstück an der Vierkantstange überfahren und diese in die um 45° verdrehte Stellung gebracht, in der die gangflügelseitige Sperrvorrichtung gegen die Schließrichtung des Gangflügels wirksam ist.This object is achieved by the characterizing features of claim 1. The two sliding pieces at the ends of the swivel arms of the door closers are connected directly by a control element in the form of a rotatable square bar. Thus, the square rod is rotated in the closed position both in the closing and in the opening direction by displacing the leaf-side slide, which changes its effective diameter due to the two rotational positions compared to the locking device arranged in the leaf. This locking device is thus acted upon in a particularly simple manner in the decisive locking position areas of the passive leaf via the torque coupling on the sliding block on the passive leaf side. In the closed position of the passive leaf, the slide on the passive leaf side has run over the transition piece on the square rod and has brought it into the position rotated by 45 °, in which the active leaf-side locking device is effective against the closing direction of the active leaf.

Eine besonders vorteilhafte drehmomentenschlüssige Verbindung des standflügelseitigen Gleitstückes mit der Vierkantstange ist in Anspruch 2 angegeben.A particularly advantageous torque-locking connection of the passive leaf-side slider with the square rod is specified in claim 2.

Bevorzugte wird die gangflügelseitige Sperrvorrichtung gemäß den Ansprüchen 3, 4, 5 und 6 vorgeschlagen. Eine solche Sperrvorrichtung bildet gleichzeitig eine Überlastsicherung in der Art einer Rutschkupplung. Sobald die Überlast am Gangflügel bei Sperrung von der Standflügelseite her zu hoch wird, wird die Reibkraft der Sperrvorrichtung an der Innenseite der Führungsschiene überwunden, so daß sich der Gangflügel trotz Sperrung verschieben läßt.The locking device on the active leaf side is preferably proposed according to claims 3, 4, 5 and 6. Such a locking device simultaneously forms an overload protection device in the manner of a slip clutch. As soon as the overload on the active leaf closes from the passive leaf side when locked is high, the frictional force of the locking device on the inside of the guide rail is overcome, so that the active leaf can be moved despite locking.

Um die Schließfolgevorrichtung einstellen bzw. an verschiedene Türbreiten anpassen zu können, werden Maßnahmen gemäß den Ansprüchen 7 und 8 vorgeschlagen.In order to be able to adjust the closing sequence device or adapt it to different door widths, measures according to claims 7 and 8 are proposed.

Bei der in Fig. 1 dargestellten Feuerschutztür ist der geöffnete Standflügel mit der Ziffer 1 und der ebenfalls geöffnete Gangflügel mit der Ziffer 2 bezeichnet. Beide Türflügel sind am Türrahmen 8 angelenkt. Die beiden Flügel 1 und 2 sind mit den Türschließern 11 bzw. 21 ausgestattet. Ihre angelenkten Schwenkarme 12 bzw. 22 gleiten mit türrahmenseitigen, aus Figur 2 erkennbaren Gleitstücken 14 bzw. 24 in einer im Querschnitt C-förmigen Führungsschiene 3 an der oberen Türrahmenzarge 81. Die Drehachsen zwischen den Gleitstücken 14 bzw. 24 und den Schwenkarmen 12 bzw. 22 sind mit den Ziffern 13 und 23 angegeben.In the fire protection door shown in FIG. 1, the open passive leaf is identified by the number 1 and the likewise open active leaf by the number 2. Both door leaves are hinged to the door frame 8. The two leaves 1 and 2 are equipped with door closers 11 and 21, respectively. Your articulated swivel arms 12 and 22 slide with slide pieces 14 and 24 on the door frame side, which can be seen in FIG. 2, in a cross-sectionally C-shaped guide rail 3 on the upper door frame frame 81. 22 are indicated by the numbers 13 and 23.

Wie aus Figur 2 ersichtlich, sind die beiden Gleitstücke 14 und 24 zur Schließfolgeregelung über eine als Steuerglied dienende Vierkantstange 6 bzw. eine entsprechende im Prinzip unrunde andere Stange verbunden. Diese Vierkantstange 6 weist etwa mittig ein um ca. 45° verdrilltes Übergangsstück 61 auf. Die Enden der Vierkantstange 6 sind mit den Ziffern 62 bzw. 63 bezeichnet. Diese Vierkantstange 6 ist verdrehbar und in axialer Richtung fixiert in der Führungsschiene 3 aufgenommen. Das Ende 62 ist drehmomentenschlüssig im standflügelseitigen Gleitstück 14 aufgenommen. Das Ende 63 durchdringt das gangflügelseitige Gleitstück 24.As can be seen from FIG. 2, the two sliding pieces 14 and 24 are connected for closing sequence control via a square rod 6 serving as a control element or a corresponding, in principle, non-circular rod. This square rod 6 has a transition piece 61 twisted approximately in the middle by approximately 45 °. The ends of the square rod 6 are designated by the numbers 62 and 63, respectively. This square rod 6 is rotatable and fixed in the axial direction in the guide rail 3. The end 62 is torque-locked in the leaf-side slide 14. The end 63 penetrates the slider 24 on the active leaf side.

Wie aus den Figuren 3 und 4 ersichtlich, ist das standflügelseltige Gleitstück 14, welches beispielsweise aus einem gleitfähigen Kunststoff besteht, formschlüssig geführt in der Führungsschiene 3 aufgenommen. In seinem mittleren Bereich ist ein relativ schmales Führungsstück 4, beispielsweise aus Metall, eingesetzt mit der Durchbrechung 41 in Vierkantform entsprechend dem Querschnitt des Endes 62 der Vierkantstange 6. Zur Durchführung des Endes 62 ist das Gleitstück 14 in zylindrischer Form durchbohrt. Die Bohrung trägt die Ziffer 141.As can be seen from FIGS. 3 and 4, the fixed-wing sliding piece 14, which consists, for example, of a slidable plastic, is received in a form-fitting manner in the guide rail 3. In its central region, a relatively narrow guide piece 4, for example made of metal, is used with the opening 41 in a square shape corresponding to the cross section of the end 62 of the square rod 6. To carry out the end 62, the slide piece 14 is pierced in a cylindrical shape. The bore bears the number 141.

Die Stellung des Gleitstückes 14 entspricht der Öffnungsstellung des Standflügels 1 in Figur 1. Dabei befindet sich das Gleitstück 14 links neben dem Übergangsstück 61 der Vierkantstange 6. In dieser Stellung ist das andere Ende 63 um 45° gegenüber dem Ende 62 verdreht. Wird der Standflügel 1 in die Schließlage gebracht, so schiebt sich das Gleitstück 14 mit dem darin aufgenommenen Führungsstück 4 über das um 45° verdrillte Übergangsstück 61 der Vierkantstange 6 und verdreht diese um 45°. Das Gleitstück befindet sich danach in der in Figur 8 gestrichelt angedeuteten Stellung.The position of the slide piece 14 corresponds to the open position of the passive leaf 1 in FIG. 1. The slide piece 14 is located to the left of the transition piece 61 of the square rod 6. In this position, the other end 63 is rotated 45 ° relative to the end 62. If the inactive leaf 1 is brought into the closed position, the slide piece 14 with the guide piece 4 accommodated therein is pushed over the transition piece 61 of the square rod 6 twisted by 45 ° and rotated by 45 °. The slider is then in the position indicated by dashed lines in Figure 8.

Wie aus den Figuren 5 - 7 ersichtlich, durchdringt das andere Ende 63 der Vierkantstange 6 mit Spiel die durchgehende zylindrische Bohrung 241 im gangflügelseitigen Gleitstück 24. Dieses Gleitstück 24 nimmt die insgesamt mit der Ziffer 5 bezeichnete Sperrvorrichtung auf, die zur Schließfolgeregelung über die verdrehbare Vierkantstange 6 bzw. das Ende 62 vom Standflügel 1 her betätigt wird. Zur Bildung der Sperrvorrichtung 5 ist im Gleitstück 24 eine zur Seitenwand 31 der Führungsschiene 3 hin offene Kammer 242 ausgebildet, die zwei Keilstücke 51 und 52 aneinanderliegend aufnimmt. Das äußere Keilstück 51 weist an der zur Seitenwand 31 gerichteten Seite einen Reibbelag 53 auf. Wie insbesondere aus Figur 7 ersichtlich, ist dieses Keilstück 51 begrenzt in einen Freiraum 243 im Gleitstück 24 verschiebbar. Über die verstellbare, in das Keilstück 51 eingeschraubte Kopfschraube 7 ist der Verschiebeweg dieses Keilstückes 51 einrichtbar. Der nach außen ragende Kopf 71 begrenzt diesen Weg. Das innere Keilstück 52 ragt in die Bohrung 241 des Gleitstückes 24 hinein und liegt in jeder Drehstellung am Ende 62 der Vierkantstange 6 an. Der Schaft der Kopfschraube 7 ist durch die glatte Bohrung 241 des Gleitstückes 24 geführt.As can be seen from FIGS. 5-7, the other end 63 of the square rod 6 penetrates with play the through cylindrical bore 241 in the sliding leaf 24 on the active leaf side 6 or the end 62 is actuated from the passive leaf 1. To form the locking device 5, a chamber 242, which is open toward the side wall 31 of the guide rail 3 and which accommodates two wedge pieces 51 and 52 adjacent to one another, is formed in the slide piece 24. The outer wedge piece 51 has a friction lining 53 on the side facing the side wall 31. As can be seen in particular from FIG. 7, this wedge piece 51 can be displaced to a limited extent into a free space 243 in the sliding piece 24. The displacement of this wedge piece 51 can be set up via the adjustable head screw 7 screwed into the wedge piece 51. The outwardly projecting head 71 limits this path. The inner wedge piece 52 protrudes into the bore 241 of the slide piece 24 and is in any rotational position at the end 62 of the square rod 6. The shaft of the cap screw 7 is guided through the smooth bore 241 of the slider 24.

Bei gleichzeitig geöffnetem Standflügel 1 und Gangflügel 2 wie in Figur 1 dargestellt, drückt das Ende 62 mit der entsprechenden Kante die beiden Keilstücke 51 und 52 nach außen in Richtung auf die Seitenwand 31 der Führungsschiene 3. Ein Schließdruck vom Gangflügel 2 her verschiebt das Gleitstück 24 mit dem darin in Verschieberichtung festgesetzten Keilstück 52 in Richtung auf das Übergangsstück 61 und drückt dabei über die Keilflächen das Keilstück 51 mit seinem Reibbelag 53 zur Sperrung der Bewegung gegen die Seitenwand 31 oder Führungsschiene 3, so daß der Gangflügel 2 nicht geschlossen werden kann. Erst bei Erreichen einer bestimmten Überlast rutscht der Reibbelag 53 auf der Seitenwand 31, so daß eine Schließung des Gangflügels gegen erheblichen Druck möglich ist, ohne den Türschließer 21 bzw. den Schwenkarm 22 zu zerstören.When the passive leaf 1 and active leaf 2 are opened at the same time as shown in FIG. 1, the end 62 presses with the corresponding edge, the two wedge pieces 51 and 52 outwards in the direction of the side wall 31 of the guide rail 3. A closing pressure from the active leaf 2 shifts the slide piece 24 with the wedge piece 52 fixed therein in the direction of displacement in the direction of the transition piece 61 and thereby presses over the wedge surfaces the wedge piece 51 with its friction lining 53 to block the movement against the side wall 31 or guide rail 3, so that the active leaf 2 cannot be closed. Only when a certain overload is reached does the friction lining 53 slide on the side wall 31, so that it is possible to close the active leaf against considerable pressure without destroying the door closer 21 or the swivel arm 22.

Bei Schließung des Standflügels 1 wird, wie aus Figur 8 ersichtlich, das Ende 62 der Vierkantstange 6 um 45° verdreht, so daß eine Flachseite des Endes 62 am Keilstück 52 anliegt und dabei den Reibbelag 53 am äußeren Keilstück 51 nur noch mit geringem Druck an der Seitenwand 31 anpreßt. Das Gleitstück 24 ist in dieser Situation im Prinzip frei beweglich auf dem Ende 62. Dabei kann durch entsprechende Abmessungen eine Einstellung erreicht werden, bei der der Gangflügel 2 in jeder Öffnungsstellung stehen bleibt infolge geringfügiger Bremskraft zwischen Reibbelag 53 und Seitenwand 31.When the inactive leaf 1 is closed, as can be seen from FIG. 8, the end 62 of the square rod 6 is rotated by 45 °, so that a flat side of the end 62 rests on the wedge piece 52 and the friction lining 53 on the outer wedge piece 51 is only under slight pressure the side wall 31 presses. In this situation, the slider 24 is in principle freely movable on the end 62. A setting can be achieved by appropriate dimensions, in which the active leaf 2 remains in any open position due to a slight braking force between the friction lining 53 and the side wall 31.
