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 doppelflüglige Tür mit Schließfolgeregelung, insbesondere eine feuerhemmenden Tür, nach dem Oberbegriff des Anspruches l.The invention relates to a double-leaf door with closing sequence control, in particular a fire-retardant door, according to the preamble of claim l.

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 Dämpungselement auszurüsten, der 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 doppelflügligen 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-OS 2 918 730.According to the relevant regulations, both the passive leaf and the active leaf of a fire-retardant door are equipped with door closers that ensure the automatic closing of the door leaf. It is known to equip the active leaf with a hydraulic damping element which dampens the closing movement of the spring-loaded door half 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 the 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-OS 2 918 730.

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 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 closing the The check valve blocks the return flow 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 doppelflügligen feuerhemmenden Tür mit einer Einrichtung zum Dämpfen der Schließbewebung 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 invention task, the device of the type mentioned is characterized in that a control valve which is directly or indirectly actuatable via the passive leaf is arranged in the overflow line for closing sequence control in the overflow line.

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, one pressure chamber is connected to the other pressure chamber via an external overflow line.

Die Erfindung nutzt das ansich 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 solange gesperrt werden, bis der Standflügel geschlossen ist.The invention uses the already known damping element of the active leaf for the necessary closing sequence control. By the used in the overflow line Control valve can be locked in a simple manner, the operation of the active leaf until the passive leaf is closed.

Anhand eines abgebildeten Ausführungsbeispieles eines Zahnstangenschließers wird die erfindungsgemäße Schließfolgeregelung einer zweiflügligen 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 rack and pinion 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. der zugehörigen Zarge einer doppelflügligen 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 with the number 3 is either attached directly to the inactive leaf (not shown) or 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 at the appropriate point. to arrange.

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 can be displaced 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.

In 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 with the connection 16 to the pressure chamber 11 and with the connection 17 to the pressure chamber 12, 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 which is laid on the outside. However, there is also the possibility of this valve in the housing 1 in the overflow line to arrange and to arrange only one control element, for example with electromagnetic actuation 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.
