Description

Die Erfindung betrifft eine federbetätigte Pendeltür mit einem Federspannhebelpaar, dessen Befestigung an der Pendeltür, an einer Zarge oder am Türsturz gegenüber der Schwenkachse der Pendeltür nach innen versetzt ist, wobei das Federspannhebelpaar an einer Rolle derart anliegt, daß die Pendeltür in Schließrichtung beaufschlagbar ist und wobei die das Federspannhebelpaar ausbildenden Federspannhebel Ausnehmungen aufweisen, in die die Rolle in die Ruhelage der Pendeltür eingreift.The invention relates to a spring-operated swing door with a pair of spring tension levers, the attachment of which to the swing door, to a frame or to the lintel is offset inwards with respect to the pivot axis of the swing door, the spring tension lever pair resting against a roller such that the swing door can be acted upon in the closing direction and wherein the spring tension lever pair forming the spring tension lever have recesses into which the roller engages in the rest position of the swing door.

Eine solche Pendeltür mit am Türsturz befestigter Rolle beschreibt die FR-A-1 581 183. Die Federspannhebel sind dort als Blattfedern ausgebildet. Die erwähnten Ausnehmungen sind an den freien Enden der Blattfedern ausgebildet. Die Rolle befindet sich zwischen dem Befestigungspunkt des Federspannhebelpaars an der Pendeltür und der Schwenkachse der Pendeltür.Such a swing door with a roller attached to the lintel is described in FR-A-1 581 183. The spring tensioning levers are designed there as leaf springs. The mentioned recesses are formed on the free ends of the leaf springs. The roller is located between the point of attachment of the pair of spring tension levers on the swing door and the pivot axis of the swing door.

Durch diese Konstruktion bedingt, steigt die Schließkraft des Türschließers dieser bekannten Pendeltür mit wachsendem Öffnungswinkel der Pendeltür an. Im Ruhezustand der Pendeltür ist die von den Blattfedern auf die Pendeltür ausgeübte Schließkraft gleich Null oder zumindest sehr gering. Eine solche Charakteristik ist aber nachteilig, weil schon geringe Winddrücke die Pendeltür öffnen können. Auch muß zum Öffnen der Pendeltür eine mit wachsendem Öffnungswinkel ansteigende Kraft aufgewendet werden, was ebenfalls unerwünscht ist. Weiterhin fällt dort nachteilig ins Gewicht, daß sich die Pendeltür nur bis zu einem Winkel von etwa 45° öffnen läßt. Wird die Pendeltür über diesen Winkel hinaus aufgeschwenkt, so rastet die Rolle aus der betreffenden Blattfeder aus, und der Türschließer ist nicht mehr funktionsfähig.Due to this construction, the closing force of the door closer of this known swing door increases with an increasing opening angle of the swing door. When the swing door is at rest, the closing force exerted by the leaf springs on the swing door is zero or at least very low. However, such a characteristic is disadvantageous because even low wind pressures can open the swing door. Also, a force increasing with increasing opening angle must be used to open the swing door, which is also undesirable. Another disadvantage is that the swing door can only be opened up to an angle of approximately 45 °. If the swing door is swung open beyond this angle, the roller disengages from the relevant leaf spring and the door closer is no longer functional.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Pendeltür der eingangs genannten Art so auszugestalten, daß in der Ruhelage ein hoher Schließdruck oder Zuhaltedruck auf die Pendeltür einwirkt, der zunächst steil ansteigt und dann mit wachsendem Öffnungswinkel zumindest nicht mehr ansteigt, vorzugsweise abfällt, wobei sehr große Öffnungswinkel von fühlbar über45° möglich sein sollen.The invention is therefore based on the object of designing a swing door of the type mentioned in such a way that a high closing pressure or locking pressure acts on the swing door in the rest position, which initially rises steeply and then at least no longer rises, preferably falls, with increasing opening angle, with a very large decrease large opening angles of noticeably over 45 ° should be possible.

Zur Lösung dieser Aufgabe ist die Erfindung dadurch gekennzeichnet, daß

  • a) eine als Türschließer wirkende Feder vorgesehen ist, die an den Federspannhebeln angreift,
  • b) die Federspannhebel sich über ihre Ausnehmungen hinaus erstrecken und
  • c) die Befestigung der Federspannhebel als Schwenkbefestigung an der Schwenkachse des Türschließers ausgebildet ist, die zwischen der Schwenkachse der Pendeltür und der Rolle angeordnet
To achieve this object, the invention is characterized in that
  • a) a spring acting as a door closer is provided, which acts on the spring tensioning levers,
  • b) the spring tension levers extend beyond their recesses and
  • c) the fastening of the spring tensioning lever is designed as a swivel fastening on the swivel axis of the door closer, which is arranged between the swivel axis of the swing door and the roller

Durch das Merkmal a) wird erreicht, daß die Federspannkraft den jeweils örtlichen Verhältnissen sehr gut angepaßt werden kann. Dies ist beim geschilderten Stand der Technik ohne konstruktive Änderungen nicht möglich. Die Feder kann außerdem in einem jeweils gewünschten Maße vorgespannt werden, wodurch dann ein entsprechender Schließdruck auch in der Ruhelage auf die Pendeltür einwirkt.Characteristic a) ensures that the spring tension can be adapted very well to the respective local conditions. In the described prior art, this is not possible without design changes. The spring can also be pretensioned to the desired degree, which then causes a corresponding closing pressure to act on the swing door even in the rest position.

Das Merkmal b) ermöglicht die angestrebten großen Öffnungswinkel bis etwa 150°. Dasselbe gilt für das Merkmal c), wodurch die Befestigung des Federspannhebelpaares erfindungsgemäß viel näher an die Schwenkachse der Tür gerückt wird als dies beim Stand der Technik der Fall ist.Feature b) enables the desired large opening angles of up to approximately 150 °. The same applies to feature c), whereby the fastening of the pair of spring tension levers according to the invention is moved much closer to the pivot axis of the door than is the case in the prior art.

Es sind zwar bereits Pendeltüren mit einem Schwenkbereich bis etwa 180° bekannt, der durch ein kombiniertes Federbandscharnier mit zwei Schwenkachsen je Türflügel erreicht wird, jedoch haben diese Pendeltüren nicht die neuartige Federcharakteristik und sind auch konstruktiv aufwendiger.Swing doors with a swivel range of up to approximately 180 ° are already known, which is achieved by a combined spring hinge with two swivel axes per door leaf, but these swivel doors do not have the novel spring characteristics and are also more complex to construct.

Man kann eine weitere Vergrößerung des Schwenkwinkels der Pendeltür in einer Richtung - d. h. nach innen oder außen - erreichen, wenn die Schwenkachse der Pendeltür gegenüber der Mittelebene des Türsturzes seitlich versetzbar ist.One can further increase the swing angle of the swing door in one direction - i.e. H. inwards or outwards - when the pivot axis of the swing door can be moved laterally relative to the central plane of the lintel.

Es dient einer Einstellung der Pendeltür relativ zur Zarge, wenn an der Pendeltür verstellbare Anschläge vorgesehen sind, an denen die Federspannhebel anliegen.It is used to adjust the swing door relative to the frame if adjustable stops are provided on the swing door, against which the spring tension levers rest.

Falls auf die Federspannhebel als Feststeller dienende Anschläge für die Rolle aufgeschoben sind, die an ihrem Federspannhebel arretierbar sind, kann die Pendeltür bei einem bestimmten Öffnungswinkel in der Offenstellung jeweils arretiert werden. Dieser Öffnungswinkel hängt vom Ort der Festlegung des betreffenden Anschlages auf seinem Federspannhebel ab.If stops for the roller serving as locks are slid onto the spring tensioning levers and can be locked on their spring tensioning levers, the swing door can be locked in the open position at a certain opening angle. This opening angle depends on the location of the stop in question on its spring tension lever.

Diesbezüglich wird es bevorzugt, wenn die Anschläge an ihrer zur Schwenkachse des Türschließers weisenden Seite ein flaches Auflaufprofil und an der der Schwenkachse abgewandten Seite ein steileres Auflaufprofil für die Rolle haben.In this regard, it is preferred if the stops have a flat ramp profile on their side facing the pivot axis of the door closer and a steeper ramp profile for the roller on the side facing away from the pivot axis.

Die Erfindung wird im folgenden anhand von Ausführungsbeispielen näher erläutert, aus denen sich weitere wichtige Merkmale ergeben. Es zeigt

  • Fig. 1 eine teilweise geschnittene Seitenansicht des oberen Endes einer Pendeltür;
  • Fig.2 einen Schnitt längs der Linie 11-11 von Fig. 1;
  • Fig.3 eine Draufsicht auf eine an einem Winkelrahmen befestigte Pendeltür, wobei gleichzeitig der Schwenkwinkel der Tür dargestellt ist;
  • Fig. 4 eine weitere Draufsicht, wobei auf die Federspannhebel als Feststeller dienende Anschläge aufgeschoben sind;
  • Fig. 5 eine teilweise geschnittene Seitenansicht von Fig. 4.
The invention is explained in more detail below on the basis of exemplary embodiments, from which further important features result. It shows
  • Figure 1 is a partially sectioned side view of the upper end of a swing door.
  • 2 shows a section along the line 11-11 of Fig. 1;
  • 3 shows a plan view of a swing door fastened to an angular frame, the pivot angle of the door being shown at the same time;
  • 4 shows a further top view, with stops serving as locking being pushed onto the spring tensioning levers;
  • 5 is a partially sectioned side view of FIG. 4th

Eine Pendeltür 1 ist über Angeln, von denen in Fig. 1 nur die obere Angel 2 zeichnerisch dargestellt ist, an einer Zarge 3 schwenkbar befestigt. Die Schwenkachse der Pendeltür ist mit Position 4 bezeichnet.A swing door 1 is about fishing, of which in Fig. 1 only the upper hinge 2 is shown in the drawing, pivotally attached to a frame 3. The pivot axis of the swing door is labeled position 4.

Ein federbetätigter Türschließer 5 hat eine Schwenkachse 6. Seine Feder ist bei Position 7 angedeutet. Die Federkraft kann in bekannter Art und Weise über eine Gewindemutter 8, mit der eine Feststellmutter 9 zusammenarbeitet, eingestellt werden.A spring-operated door closer 5 has a pivot axis 6. Its spring is indicated at position 7. The spring force can be adjusted in a known manner via a threaded nut 8 with which a locking nut 9 cooperates.

Die Feder 7 beaufschlagt zwei Federspannhebel 10, 11, die ein Federspannhebelpaar ausbilden. Beide Federspannhebel werden mittels der Feder 7 zusammengedrückt, so daß sie in der zeichnerisch dargestellten Ruhelage der Pendeltür an einer Rolle 12 anliegen. Diese ist am oberen waagerechten Teil der Zarge 3 oder am oberen Türsturz drehbar befestigt. In der gezeigten Ruhelage liegt die Rolle 12 in Ausnehmungen 13 der Federspannhebel..The spring 7 acts on two spring tension levers 10, 11, which form a pair of spring tension levers. Both spring tensioning levers are pressed together by means of the spring 7, so that they rest on a roller 12 in the illustrated rest position of the swing door. This is rotatably attached to the upper horizontal part of the frame 3 or to the upper lintel. In the rest position shown, the roller 12 lies in recesses 13 of the spring tensioning lever.

An der Pendeltür 1 ist weiterhin ein Ansatz 14 befestigt, in den übereinander zwei Gewindeschrauben 15 eingeschraubt sind, von denen zeichnerisch nur eine dargestellt ist. Durch eine entsprechende Einstellung der Gewindeschrauben wird die Spreizung der Federspannhebel 10, 11 eingestellt und damit auch die Lage der Pendeltür relativ zur Zarge.On the swing door 1, an extension 14 is also attached, in which two threaded screws 15 are screwed one above the other, of which only one is shown in the drawing. The spreading of the spring tensioning levers 10, 11 and thus also the position of the swing door relative to the frame are adjusted by a corresponding adjustment of the threaded screws.

Wird die Pendeltür in Richtung des Doppelpfeiles 16 geöffnet, so wandert dabei die Rolle 12 aus der Ausnehmung 13 des betreffenden Federspannhebels 10 oder 11 in Pfeilrichtung 17 heraus. Dadurch vergrößert sich der Hebelarm zwischen dem momentanen Antagepunkt zwischen Rolle 12 und Federspannhebel 10 oder 11 - in Fig. 2 ist dieser Anlagepunkt die Mitte der Ausnehmung 13 - und der Schwenkachse 6 des Türschließers 5. Bedingt durch diesen sich hierbei vergrößernden Federarm bleibt die von der Feder 7 ausgeübte Schließkraft bei sich öffnender Pendeltür gleich. Vorzugsweise verringert sie sich mit sich vergrößerndem Öffnungswinkel. Dies beruht darauf, daß die von der Feder 7 ausgeübte Schließkraft zwar mit sich vergrößerndem Öffnungswinkel wächst, dieser Anstieg aber durch den sich gleichzeitig vergrößerndem Hebelarm zwischen dem momentanen Anlagepunkt des betreffenden Hebelarms an der Rolle und der Schwenkachse des Türschließers zumindest kompensiert wird.If the swing door is opened in the direction of the double arrow 16, the roller 12 migrates out of the recess 13 of the spring tension lever 10 or 11 in question in the direction of the arrow 17. This increases the lever arm between the current point of contact between the roller 12 and the spring tension lever 10 or 11 - in Fig. 2, this contact point is the center of the recess 13 - and the pivot axis 6 of the door closer 5. Due to this increasing spring arm remains the of Spring 7 exerted the same closing force when the swing door opens. It preferably decreases as the opening angle increases. This is due to the fact that the closing force exerted by the spring 7 increases with an increasing opening angle, but this increase is at least compensated for by the lever arm, which increases at the same time, between the momentary contact point of the relevant lever arm on the roller and the pivot axis of the door closer.

Die Versetzung der Schwenkachse 6 des Türschließers nach innen ermöglicht den fühlbar vergrößerten Öffnungswinkel, weil dadurch das Gehäuse des Türschließers 5 einen größeren Abstand von der Zarge 3 bzw. der entsprechenden Wand des Gebäudes einnimmt.The inward displacement of the pivot axis 6 of the door closer enables the noticeably increased opening angle, because as a result the housing of the door closer 5 is at a greater distance from the frame 3 or the corresponding wall of the building.

Will man den Öffnungswinkel nach einer Richtung (innen oder außen) noch weiter vergrößern, so versetzt man die Angel 2 mit ihrer Schwenkachse 4 seitlich, wie in Fig. 2 bei Pos.-2' und 4' angedeutet. Dies ist durch ein entsprechendes und an die Zarge 3 angeschraubtes Winkelprofil möglich.If you want to further increase the opening angle in one direction (inside or outside), you move the hinge 2 laterally with its pivot axis 4, as indicated in FIG. 2 at items 2 'and 4'. This is possible through a corresponding angle profile screwed onto the frame 3.

Die zeichnerisch beschriebene Ausführungsform kann auch abgewandelt werden. Beispielsweise kann auch die Rolle auf der Oberkante des Türflügels der Pendeltür 1 drehbar befestigt sein, in welchem Fall dann der Türschließer mit seinen Federspannhebeln an der Unterkante des Türsturzes befestigt ist.The embodiment described in the drawing can also be modified. For example, the roller can also be rotatably fastened on the upper edge of the door leaf of the swing door 1, in which case the door closer is then fastened to the lower edge of the lintel with its spring tension levers.

Die beschriebenen Pendeltüren sind üblicherweise paarweise angeordnet.The swing doors described are usually arranged in pairs.

Der Abstand zwischen den Schwenkachsen 4 und 6 richtet sich nach den jeweiligen Gegebenheiten. Je größer dieser Abstand ist, um so größer wird der mit der Erfindung erzielbare Effekt, d. h. um so stärker wird die vom Türschließer auf die Pendeltür ausgeübte Rückstellkraft in Abhängigkeit vom Öffnungswinkel der Pendeltür beeinflußt.The distance between the pivot axes 4 and 6 depends on the particular circumstances. The greater this distance, the greater the effect that can be achieved with the invention, i. H. the restoring force exerted by the door closer on the swing door is influenced as a function of the opening angle of the swing door.

Durch das Versetzen der Schwenkachse 6 nach innen geht zwar ein gewisses Maß an Durchfahrbreite verloren, dies beträgt aber nur etwa 50-55mm und fällt daher nicht ins Gewicht.By moving the swivel axis 6 inwards, a certain amount of passage width is lost, but this is only about 50-55mm and is therefore not significant.

In Fig. 3 ist die Pendeltür an einem Winkelprofil 18 befestigt. Fernerhin ist dort der Öffnungswinkel von 150° eingezeichnet.In Fig. 3 the swing door is attached to an angle section 18. The opening angle of 150 ° is also shown there.

In Fig. 4 und 5 ist auf die Federspannhebel 10, 11 je ein als Feststeller dienender Anschlag 19 aufgeschoben und an der gewünschten Stelle längs des Federspannhebels arretiert, beispielsweise mittels einer Schraube. Dadurch kann der Türflügel in geöffnetem Zustand bei Bedarf arretiert werden.4 and 5, a stop 19 serving as a lock is pushed onto the spring tensioning levers 10, 11 and locked at the desired location along the spring tensioning lever, for example by means of a screw. As a result, the door leaf can be locked in the open state if necessary.

Die Anschläge 19 sind stufenlos auf den Federspannhebeln einstellbar. An ihrer zur Schwenkachse 6 des Türschließers weisenden Seite haben sie ein flaches Auflaufprofil 20 und an der entgegengesetzten Seite ein steileres Auflaufprofil 21.The stops 19 are infinitely adjustable on the spring tension levers. On their side facing the pivot axis 6 of the door closer they have a flat overrun profile 20 and on the opposite side a steeper overrun profile 21.

Beim Öffnen der Tür gleitet die Rolle 12 somit leicht über den Anschlag 19 hinweg, während die Tür, bedingt durch den Federdruck, beim Schließen in gewünschtem und einstellbarem Öffnungswinkel dadurch arretiert wird, daß sich

Figure imgb0001
Rolle 12 an das steilere Auflaufprofil 21 anlegt. Erst durch festeres Drücken der Tür in Schließrichtung oder durch einen leichten Schwung gleitet die Rolle über den Anschlag 19 hinweg, und die Tür schließt selbsttätig.When the door is opened, the roller 12 thus slides easily over the stop 19, while the door, due to the spring pressure, is locked when closing in the desired and adjustable opening angle in that
Figure imgb0001
 Roll 12 applies to the steeper ramp profile 21. Only when the door is pressed more firmly in the closing direction or by a slight swing does the roller slide over the stop 19 and the door closes automatically.

In Fig. 4 ist die Pendeltür in ihrer geschlossenen Lage und gleichzeitig in einer geöffneten, arretierten Lage gezeigt.In Fig. 4 the swing door is shown in its closed position and at the same time in an open, locked position.
