Abstract

1. A double-leaf door which is spring-loaded in the closing direction and which has a device for damping the closing movement and a closing sequence regulator, in particular a fire retarding door, wherein the damping of the trailing leaf takes place via a hydraulic damping element with a throttled transfer flow between two pressure chambers which are controlled in opposite senses by a double acting piston, characterised in that a control valve (3) which is directly or indirectly actuatable via the leading leaf is arranged in the transfer flow passage (2) from the one pressure chamber (11 or 12 respectively) to the other.

Description

Die Erfindung betrifft eine doppelflügelige Tür mit Schliessfolgeregelung, insbesondere eine feuerhemmende Tür nach dem Oberbegriff des Anspruches 1. Eine solche Tür mit Schliessfolgeregelung ist z. B. aus der GB-A Nr. 2067656 bekannt.The invention relates to a double-leaf door with closing sequence control, in particular a fire-retardant door according to the preamble of claim 1. Such a door with closing sequence control is, for. B. from GB-A No. 2067656 known.

Sowohl der Standflügel als auch der Gehflügel einer feuerhemmenden Tür sind nach den einschlägigen Vorschriften mit Türschliessern ausgestattet, die für die automatische Schliessung der Türflügel sorgen. Es ist bekannt, den Gehflügel mit einem hydraulischen Dämpfungselement auszurüsten, das die Schliessbewegung der in Schliessrichtung federbelasteten Türhälfte in einem bestimmten Schliesswinkelbereich dämpft. Diese Dämpfung wird kurz vor Beendigung der Schliessbewegung ausser Kraft gesetzt. Bei diesen doppelflügeligen feuerhemmenden Türen wird ausserdem eine Schliessfolge gefordert, mit der sicherzustellen ist, dass der Gehflügel, der in der Regel das Schloss und den Türgriff aufnimmt, erst dann geschlossen werden kann, wenn der sogenannte Standflügel geschlossen ist. Für eine solche Schliessfolgeregelung sind verschiedene mechanische Vorrichtungen bekannt mit aufwendigen Hebelgestängen und Federanordnungen, beispielsweise nach der DE-A Nr. 2918730 oder der GB-A Nr. 2067656.Both the passive leaf and the active leaf of a fire-retardant door are equipped with door closers according to the relevant regulations, which ensure the automatic closing of the door leaves. It is known to equip the active leaf with a hydraulic damping element which dampens the closing movement of the door half which is spring-loaded in the closing direction in a certain closing angle range. This damping is overridden shortly before the closing movement ends. These double-leaf fire-retardant doors also require a closing sequence to ensure that the active leaf, which usually houses the lock and door handle, can only be closed when the so-called passive leaf is closed. Various mechanical devices are known for such a closing sequence control with complex lever linkages and spring arrangements, for example according to DE-A No. 2918730 or GB-A No. 2067656.

Für die Dämpfung der Schliessbewegung des Gehflügels einer feuerhemmenden Tür werden vor allem sogenannte hydraulische Zahnstangenschliesser eingesetzt. Das zylinderartige Gehäuse eines solchen Dämpfungselementes wird in der Regel an der Türzarge befestigt. In seinem Inneren ist gegen einen Federdruck ein doppelwirkender Kolben verschiebbar, der zwei Druckräume gegeneinander trennt. Über ein Zahnstangengetriebe und einen entsprechenden Hebel ist der Gehflügel mit dem Kolben verbunden. Während der Öffnungsbewegung des Gehflügels wird der Kolben gegen eine Druckfeder verschoben. Das Druckmedium strömt aus dem sich verringernden einen Druckraum durch eine Überströmbohrung mit einem Rückschlagventil in den anderen sich vergrössernden Druckraum. Beim Schliessen der Tür sperrt das Rückschlagventil den Rückfluss des Druckmediums durch den Kolben. Durch radiale Steuerbohrungen im Zylinder gelangt das Druckmedium zu einer gedrosselten Überströmleitung, die zum anderen Druckraum führt. Durch diese Drosselung wird die Schliessbewegung gedämpft bzw. gebremst.So-called hydraulic rack and pinion closers are primarily used to dampen the closing movement of the active leaf of a fire-retardant door. The cylinder-like housing of such a damping element is usually attached to the door frame. A double-acting piston, which separates two pressure chambers from each other, can be moved inside against a spring pressure. The active leaf is connected to the piston via a rack and pinion gear and a corresponding lever. During the opening movement of the active leaf, the piston is pushed against a compression spring. The pressure medium flows from the decreasing one pressure chamber through an overflow bore with a check valve into the other increasing pressure chamber. When the door is closed, the check valve blocks the backflow of the pressure medium through the piston. Through radial control bores in the cylinder, the pressure medium reaches a throttled overflow line that leads to the other pressure chamber. This throttling dampens or brakes the closing movement.

Die Aufgabe der Erfindung besteht darin, die Schliessfolgeregelung an einer doppelflügeligen feuerhemmenden Tür mit einer Einrichtung zum Dämpfen der Schliessbewegung zu vereinfachen.The object of the invention is to simplify the closing sequence control on a double-leaf fire-retardant door with a device for damping the closing movement.

Zur Lösung dieser Erfindungsaufgabe ist die Einrichtung der eingangs genannten Art dadurch gekennzeichnet, dass zur Schliessfolgeregelung in der Überströmleitung von einem zum anderen Druckraum ein über den Standflügel direkt oder indirekt betätigbares Steuerventil angeordnet ist.To solve this task of the invention, the device of the type mentioned at the outset is characterized in that a control valve which can be actuated directly or indirectly via the passive leaf is arranged in the overflow line for closing sequence control from one pressure chamber to the other.

Nach einer bevorzugten Ausführungsart der Erfindung ist der eine Druckraum über eine äussere Überströmleitung mit dem anderen Druckraum verbunden.According to a preferred embodiment of the invention, the one pressure chamber is connected to the other pressure chamber via an outer overflow line.

Die Erfindung nutzt das an sich bekannte, ohnehin vorhandene Dämpfungselement des Gehflügels für die notwendige Schliessfolgeregelung. Durch das in der Überströmleitung eingesetzte Steuerventil kann in einfacher Weise die Betätigung des Gehflügels so lange gesperrt werden, bis der Standflügel geschlossen ist.The invention uses the damping element of the active leaf, which is known in any case and is present anyway, for the necessary closing sequence control. Through the control valve used in the overflow line, the actuation of the active leaf can be blocked in a simple manner until the passive leaf is closed.

Anhand eines abgebildeten Ausführungsbeispiels eines Zahnstangenschliessers wird die erfindungsgemässe Schliessfolgeregelung einer zweiflügeligen Tür im folgenden näher erläutert. Die Abbildung zeigt einen Schnitt durch das zylinderartige Gehäuse eines solchen hydraulischen Zahnstangenschliessers mit der ventilgesteuerten Überströmleitung.The closing sequence control according to the invention of a two-leaf door is explained in more detail below on the basis of an illustrated exemplary embodiment of a toothed rack closer. The figure shows a section through the cylinder-like housing of such a hydraulic rack and pinion closer with the valve-controlled overflow line.

Das mit der Ziffer 3 bezeichnete Steuerventil ist entweder direkt am nicht dargestellten Standflügel bzw. an der zugehörigen Zarge einer doppelflügeligen feuerhemmenden Tür befestigt. Vorgesehen kann jedoch auch eine indirekte Betätigung dieses Ventiles sein. In diesem Falle ist an der entsprechenden Stelle ein entsprechender Schalter od. dgl. anzuordnen.The control valve designated by the number 3 is either attached directly to the passive leaf, not shown, or to the associated frame of a double-leaf fire-retardant door. However, indirect actuation of this valve can also be provided. In this case, a corresponding switch or the like is to be arranged at the corresponding point.

Der dargestellte hydraulische Zahnstangenschliesser besitzt ein zylinderartiges Gehäuse 1, in dem ein doppeltwirkender Kolben 4 verschiebbar ist und zwei Druckräume 11 bzw. 12 gegeneinander trennt. Verschiebbar ist dieser Kolben 4 über ein Zahnstangengetriebe, welches mit dem nicht dargestellten Gehflügel der feuerhemmenden Tür verbunden ist.The hydraulic rack and pinion closer shown has a cylinder-like housing 1, in which a double-acting piston 4 is displaceable and separates two pressure chambers 11 and 12 from one another. This piston 4 is displaceable via a rack and pinion gear, which is connected to the non-illustrated active leaf of the fire-retardant door.

Das mit der Ziffer 5 bezeichnete zylinderförmige Zahnrad greift von aussen durch das Gehäuse in die Ausnehmung 45 des Kolbens 4 ein. Diese Ausnehmung ist mit der Längsverzahnung 44 ausgestattet.The cylindrical gearwheel designated by the number 5 engages from the outside through the housing into the recess 45 of the piston 4. This recess is equipped with the longitudinal toothing 44.

Bei der Öffnungsbewegung des Gehflügels wird der Kolben 4 gegen den Druck der Schliessfeder 6 verschoben und verkleinert den Druckraum 12. Das verdrängte Druckmedium, beispielsweise Hydrauliköl, strömt durch die Bohrungen 41 und 42 des Kolbens 4 ungehindert in den Druckraum 11.During the opening movement of the active leaf, the piston 4 is displaced against the pressure of the closing spring 6 and reduces the pressure chamber 12. The displaced pressure medium, for example hydraulic oil, flows unhindered into the pressure chamber 11 through the bores 41 and 42 of the piston 4.

I n der entsprechenden Phase der Schliessbewegung des Gehflügels wird der Kolben 4 umgekehrt bewegt. Der Druck des Öles aus dem Druckraum 11 schliesst das Rückschlagventil 43 in der Bohrung 42. Das Druckmedium kann nur durch die radialen Bohrungen 13 und 14 zum Drosselventil 15 strömen. Bei offenem Steuerventil 3 in der Überströmleitung 2, die mit dem Anschluss 16 mit dem Druckraum 11 und mit dem Anschluss 17 mit dem Druckraum 12 verbunden ist, kann das Druckmedium gedrosselt, also dämpfend bzw. bremsend, überströmen.In the corresponding phase of the closing movement of the active leaf, the piston 4 is moved in reverse. The pressure of the oil from the pressure chamber 11 closes the check valve 43 in the bore 42. The pressure medium can only flow through the radial bores 13 and 14 to the throttle valve 15. When the control valve 3 is open in the overflow line 2, which is connected to the pressure chamber 11 by the connection 16 and to the pressure chamber 12 by the connection 17, the pressure medium can flow in a throttled manner, that is to say damping or braking.

Zweckmässigerweise ist das Steuerventil 3, welches über den Standflügel betätigt wird, in einer aussen verlegten Überströmleitung untergebracht. Es besteht jedoch auch die Möglichkeit, dieses Ventil in das Gehäuse 1 in der Überströmleitung anzuordnen und nur ein Steuerelement, beispielsweise mit elektromagnetischer Betätigung, am Standflügel anzuordnen. Statt eines Hydraulikventiles können entsprechende Steuerungselemente pneumatischer oder auch elektromagnetischer Art vorgesehen werden.The control valve 3, which is actuated via the passive leaf, is expediently accommodated in an overflow line laid on the outside. However, there is also the possibility of arranging this valve in the housing 1 in the overflow line and only one control element for example with electromagnetic actuation, to be arranged on the passive leaf. Corresponding pneumatic or electromagnetic control elements can be provided instead of a hydraulic valve.

Das erfindungsgemässe Prinzip lässt sich auch an anderen Dämpfungselementen für feuerhemmende Türen einsetzen, da lediglich über den Standflügel die Betätigungsfreiheit des Dämpfungselementes zu steuern ist.

The principle according to the invention can also be used on other damping elements for fire-retardant doors, since the freedom of actuation of the damping element can only be controlled via the passive leaf.
