Description

Die Erfindung betrifft eine Feststellvorrichtung für einen Flügel einer Tür nach dem Oberbegriff des Anspruchs 1.The invention relates to a locking device for a wing of a door according to the preamble of claim 1.

Aus der EP 0 649 961 A1 ist eine Feststellvorrichtung für einen Flügel einer Tür bekannt, wobei die Tür mit einem Türschließer versehen ist, dessen Gleitarm mit einem Gleiter verschiebbar in einer Gleitschiene geführt ist. Im Gleiter ist eine um eine Achse kippbare, federbeaufschlagte Wippe angeordnet, welche zur Feststellung des Flügels in einer Offenstellung ein in der Gleitschiene festgelegtes Keilelement hintergreift. Die Kraft der auf die Wippe wirkenden Feder ist einstellbar.From the EP 0 649 961 A1 discloses a locking device for a wing of a door, wherein the door is provided with a door closer, the sliding arm is slidably guided with a slider in a slide rail. In the slider, a tiltable about an axis spring-loaded rocker is arranged, which engages behind a fixed in the slide rail wedge element for detecting the wing in an open position. The force of the spring acting on the rocker is adjustable.

Die Anordnung benötigt einen großen Einbauraum und damit eine große Gleitschiene.The arrangement requires a large installation space and thus a large slide rail.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art auszubilden, welche einen geringen Einbauraum benötigt.The invention has for its object to form a device of the type mentioned, which requires a small installation space.

Die Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst.The object is solved by the features of claim 1.

Die Unteransprüche bilden vorteilhafte Ausgestaltungsmöglichkeiten der Erfindung.The subclaims form advantageous embodiments of the invention.

Drehtüren werden mit Türschließern versehen, um nach einem manuellen Öffnen des Flügels der Drehtür ein selbstständiges Schließen des Flügels zu bewirken. Dazu kann der Türschließer am Flügel aufliegend oder im Flügel integriert angeordnet werden, wobei der Türschließer über einen Gleitarm mit einem an diesem drehbar gelagerten Gleiter in eine am Rahmen aufliegend oder im Rahmen integriert angeordnete Gleitschiene eingreift. Die Anordnung von Türschließer und Gleitschiene kann auch umgekehrt erfolgen, wobei der Türschließer am oder im Rahmen und die Gleitschiene auf oder in dem Flügel der Tür angeordnet ist. Die erfindungsgemäße Anordnung ist nicht ausschließlich auf Drehtüren beschränkt, sondern kann auch an Fenstern, Klappen oder dergleichen entsprechend verwendet werden.Hinged doors are provided with door closers to effect an independent closing of the sash after manually opening the sash of the revolving door. For this purpose, the door closer can be arranged resting on the wing or integrated in the wing, wherein the door closer engages via a sliding arm with a rotatably mounted on this slider in a frame resting on or integrated in the frame arranged sliding rail. The arrangement of door closer and slide can also be done vice versa, the door closer on or in Frame and the slide rail is arranged on or in the wing of the door. The arrangement according to the invention is not limited exclusively to hinged doors, but can also be used correspondingly on windows, flaps or the like.

Um den Flügel der Drehtür zumindest temporär geöffnet zu halten, ist eine Feststellvorrichtung erforderlich, die insbesondere bei einer integrierten Anordnung einer Gleitschiene im Flügel oder im Rahmen, was eine besonders kleine und niedrige Gleitschiene erfordert, vorteilhaft geringe Baumaße aufweist.In order to keep the wing of the revolving door at least temporarily open, a locking device is required, which advantageously has small dimensions, especially in an integrated arrangement of a slide in the wing or in the frame, which requires a particularly small and low slide.

Die besonders klein bauende, erfindungsgemäße Feststellvorrichtung weist daher einen Schlitten und eine Führung auf, welche in das C-förmige Profil der Gleitschiene einschiebbar sind und welche die weiteren Teile der Feststellvorrichtung aufnehmen. Im Schlitten ist ein Befestigungselement, beispielsweise eine Schraube, vorgesehen, mit dem die Feststellvorrichtung in ihrer Position entlang der Längserstreckung der Gleitschiene festgelegt werden kann. Durch die Position der Feststellvorrichtung in der Gleitschiene kann der Feststellwinkel des Flügels festgelegt werden, in welchem der Flügel durch die Feststellvorrichtung offen gehalten wird.The particularly compact, locking device according to the invention therefore has a carriage and a guide, which can be inserted into the C-shaped profile of the slide and which receive the other parts of the locking device. In the carriage, a fastener, such as a screw, is provided with which the locking device can be fixed in position along the longitudinal extent of the slide. By the position of the locking device in the slide rail, the locking angle of the wing can be set, in which the wing is held open by the locking device.

Ein mit einer Feder beaufschlagter, schwenkbar im Schlitten gelagerter Rasthebel, an dem ein Rastkopf mit einer Rastnase vorgesehen ist, ist zur Aufnahme des Gleiters zur Feststellung des Flügels ausgebildet. Die Feder stützt sich an einer in einem Gewinde im Schlitten verstellbaren Stellschraube ab und ist andererseits an einem in der Führung geführten Schieber abgestützt, welcher sich wiederum an einer Rolle im Rasthebel abstützt und so den Rasthebel in Richtung auf die Gleitschiene zu beaufschlagt. Durch Drehen der Stellschraube ist die Vorspannung der Feder einstellbar. Vorteilhaft sind die Feder, der Schieber und die Rolle im Rasthebel selbst angeordnet, wodurch eine besonders geringe Baugröße erzielt wird.An acted upon by a spring, pivotally mounted in the carriage locking lever on which a locking head is provided with a latching nose is formed for receiving the slider for detecting the wing. The spring is supported on an adjustable in a thread in the carriage screw and on the other hand supported on a slide guided in the guide, which in turn is supported on a roller in the locking lever and so acts on the locking lever in the direction of the slide rail. By turning the adjusting screw, the preload of the spring is adjustable. Advantageously, the spring, the slide and the roller are arranged in the locking lever itself, whereby a particularly small size is achieved.

Der Schieber ist mit einer Schrägfläche versehen, mit welcher er sich an der im Rasthebel angeordneten Rolle abstützt, wobei der Rastkopf, abhängig vom Winkel der Schrägfläche und der eingestellten Vorspannung der Feder, in Feststellrichtung beaufschlagt ist.The slider is provided with an inclined surface, with which it is supported on the roller arranged in the locking lever, wherein the locking head, depending on the angle the inclined surface and the set bias of the spring, is acted upon in the locking direction.

Am Rastkopf ist eine Rastnase ausgebildet, welche beiderseits mit Schrägen versehen ist. Gelangt der Gleiter in den Bereich der Feststellvorrichtung, so hebt dieser mit einem Rastelement, welches in einer Aussparung oder an einem Fortsatz des Gleiters angeordnet sein kann, den Rasthebel mit dem Rastkopf an, und das Rastelement gelangt hinter die Rastnase.At the locking head a locking lug is formed, which is provided on both sides with bevels. If the slider arrives in the region of the locking device, it lifts the locking lever with the locking head with a locking element, which can be arranged in a recess or on an extension of the slider, and the locking element arrives behind the locking nose.

Vorteilhaft weist die Rastnase auf seiner dem Gleiter zugewandten Seite eine flache Schräge auf, um das Verschwenken des Rasthebels zu erleichtern, während die Schräge auf der gegenüberliegenden Seite der Rastnase steiler ausgebildet ist, wodurch das Rastelement des Gleiters gehalten ist und der Flügel in seiner Offenstellung festgestellt ist.Advantageously, the locking lug on its side facing the slider on a flat slope to facilitate the pivoting of the locking lever, while the slope is formed steeper on the opposite side of the latch, whereby the latching element of the slider is held and found the wing in its open position is.

Die Feder ist dabei durch die Stellschraube so einzustellen, dass die durch den Türschließer in Schließrichtung wirkende Kraft nicht ausreicht, um das Rastelement auszulösen.The spring is adjusted by the screw so that the force acting through the door closer in the closing direction force is insufficient to trigger the locking element.

Wird der Flügel der Tür zusätzlich manuell in Schließrichtung beaufschlagt, so wird der Rasthebel durch das Rastelement entlang der Schräge an der Rastnase verschwenkt, und der Gleiter wird frei. Der Flügel kann durch den Türschließer weiter in seine Schließlage geführt werden.If the wing of the door additionally acted upon manually in the closing direction, the locking lever is pivoted by the locking element along the slope of the locking lug, and the slider is free. The wing can be guided by the door closer into its closed position.

Die Fig. 4 und 5 zeigen die Feststellvorrichtung 8 außerhalb der Gleitschiene 5 zur Verdeutlichung der Anordnung der Einzelteile aus zwei unterschiedlichen Ansichten im Schrägbild. Fig. 2 and Fig. 3 show the arrangement of a first embodiment of a locking device 8 in the slide rail 5, wherein the wing 2 is held in its open position by the slider 7 is in engagement with the locking device 8. The 4 and 5 show the locking device 8 outside the slide rail 5 to illustrate the arrangement of the items from two different views in the oblique view.

In den Fig. 6 und 7 ist ein weiteres Ausführungsbeispiel der Feststellvorrichtung 8 ebenfalls außerhalb der Gleitschiene im Schrägbild gezeigt.In the 6 and 7 is another embodiment of the locking device 8 also shown outside of the slide in the oblique view.

Die Feststellvorrichtung 8 weist einen Schlitten 9 und eine Führung 10 auf, welche beide in dem C-förmigen Profil der Gleitschiene 5 längsverschiebbar geführt sind. Zur Festlegung der Position der Feststellvorrichtung 8 innerhalb der Gleitschiene 5 ist am Schlitten 9 ein Befestigungselement 11, welches hier als Gewindestift mit Innensechskant ausgebildet ist, vorgesehen. Durch die Positionierung der Feststellvorrichtung 8 innerhalb der Gleitschiene 5 ist der Feststellwinkel für die Offenstellung des Flügels 2 einstellbar.The locking device 8 has a carriage 9 and a guide 10, which are both guided longitudinally displaceable in the C-shaped profile of the slide rail 5. Laying down the position of the locking device 8 within the slide 5 is on the carriage 9, a fastener 11, which here as a threaded pin with Hexagon socket is formed, provided. Due to the positioning of the locking device 8 within the slide rail 5, the locking angle for the open position of the wing 2 is adjustable.

Die Feststellvorrichtung 8 weist weiterhin einen einerends in einem Drehlager 12 am Schlitten 9 gelagerten, schwenkbaren Rasthebel 13 auf, an welchem andernends ein Rastkopf 14 ausgebildet ist. Der Rastkopf 14 weist eine Rastnase 15 auf, welche mit einem am Gleiter 7 angeordneten Rastelement 16 zur Feststellung des Flügels 2 in der vorgesehenen Offenstellung zusammenwirkt.The locking device 8 further has a one end mounted in a pivot bearing 12 on the carriage 9, pivotable locking lever 13, on which another end a locking head 14 is formed. The locking head 14 has a latching lug 15 which cooperates with a arranged on the slider 7 locking element 16 for detecting the wing 2 in the intended open position.

Zwischen dem Schlitten 9 und der Rastnase 15 ist in dem ausgesparten Rasthebel 13 ein von einer Feder 17 beaufschlagter Schieber 18 angeordnet, der mit der Führung 10 einstückig ausgebildet ist und durch die Führung 10 längsverschiebbar in der Gleitschiene 5 geführt ist. Weiterhin wird der Rasthebel 13 von der Führung 10 umgriffen und durch diese in Schwenkrichtung geführt. Die Führung 10 führt somit sowohl den Schieber 18 in Längsrichtung der Gleitschiene 5 als auch den Rasthebel 13 in dessen Schwenkrichtung. Die Führung 10 und der Schieber 18 können zur Reduzierung der Reibkräfte und zur Kostenreduzierung vorteilhaft aus einem Kunststoffmaterial, beispielsweise im Spritzgussverfahren, hergestellt sein und Vertiefungen und Aussparungen aufweisen, wodurch eine Materialreduzierung und gleichmäßige Wandstärken möglich sind. Damit wird ein verzugsfreies, formstabiles Bauteil mit geringen Fertigungstoleranzen erzielt. Die Feder 17 ist einerseits in der Führung 10 aufgenommen und stützt sich andererseits an einer Stellschraube 19 ab, die in einem Gewinde im Schlitten 9 aufgenommen ist.

Der im Rasthebel 13 angeordnete Schieber 18 weist eine Schrägfläche 20 auf, mit welcher sich der Schieber 18 an einer im Rasthebel 13 angeordneten Rolle 21 abstützt. Einfacher kann anstelle der Rolle 21 auch kostengünstig ein Stift oder eine Gleitschräge im Rasthebel 13 angeordnet sein, welche mit der Schrägfläche 20 des Schiebers 18 korrespondiert. Durch Verwendung der Rolle 21 wird jedoch vorteilhaft die Kraftübertragung, durch die gegenüber der Gleitreibung geringere Rollreibung, und die Auslösesicherheit verbessert. Abhängig vom Winkel der Schrägfläche 20 findet eine Kräfteaufteilung der durch die Stellschraube 19 einstellbaren Kraft der Feder 17 in eine waagrechte und seine senkrechte Komponente statt, wobei die senkrechte Kraftkomponente die Rolle 21 des Rasthebels 13 mit dem Rastkopf 14 in Feststellrichtung, d.h. in Richtung auf die Basis der Gleitschiene 5 - in der Fig. 3 nach oben - beaufschlagt. Der Rasthebel 13 befindet sich in seiner Ruhelage in der Kontur der Gleitschiene 5. Vorteilhaft ist durch die Verwendung der Rolle 21 eine steilere Schrägfläche 20 möglich, wodurch eine größere Übersetzung der Kräfte möglich ist.The slider 18 arranged in the slide 18 has an inclined surface 20, with which the slider 18 is supported on a roller 21 arranged in the locking lever 13. Easier, instead of the roller 21, a pin or a sliding bevel can also be arranged inexpensively in the detent lever 13, which corresponds to the oblique surface 20 of the slider 18. By using the roller 21, however, the power transmission is advantageously improved, by which compared to the sliding friction lower rolling friction, and the trigger safety. Depending on the angle of the inclined surface 20 is a force distribution of adjustable by the screw 19 force of the spring 17 in a horizontal and its vertical component, the vertical force component, the roller 21 of the locking lever 13 with the locking head 14 in the locking direction, ie in the direction of Base of the slide 5 - in the Fig. 3 to the top - charged. The locking lever 13 is in its rest position in the contour of the slide rail 5. Advantageously, by using the roller 21 a steeper inclined surface 20 is possible, whereby a larger translation of the forces is possible.

Durch die Anordnung der Feder 17, des Schiebers 18 und der Rolle 21 im Rasthebel 13 selbst wird eine geringe Baugröße, sowohl in der Bauhöhe als auch in der Baulänge der Feststellvorrichtung 8, erzielt.Due to the arrangement of the spring 17, the slider 18 and the roller 21 in the locking lever 13 itself is a small size, both in the overall height and in the overall length of the locking device 8, achieved.

Am mittels eines Verbindungselements 22 drehgelenkig mit dem Gleitarm 6 des Türschließers 4 verbundenen Gleiter 7 ist eine Aussparung 23 vorgesehen, in welcher das Rastelement 16 angeordnet ist. Alternativ kann der Gleiter 7 auch einen Fortsatz aufweisen, an welchem das Rastelement 16 angeordnet ist. Auch das Rastelement 16 kann, wie die Rolle 21, vorteilhaft ebenfalls als Rolle, aber auch kostengünstig als einfacher Stift ausgebildet sein.At the means of a connecting element 22 pivotally connected to the sliding arm 6 of the door closer 4 slider 7, a recess 23 is provided, in which the locking element 16 is arranged. Alternatively, the slider 7 may also have an extension on which the latching element 16 is arranged. Also, the locking element 16 may, like the roller 21, advantageously also be designed as a role, but also cost as a simple pin.

Wird der Flügel 2 der Drehtür 1 manuell geöffnet, so gelangt der Gleiter 7, abhängig von der Positionierung der Feststellvorrichtung 8 in der Gleitschiene 5, in den Bereich der Feststellvorrichtung 8, wobei zunächst das Rastelement 16 in Anlage mit der dem Rastelement 16 zugewandten Schräge 24 gelangt. Wird der Flügel 2 weiter geöffnet, so wird der Rastkopf 14 durch das Rastelement 16 entgegen der durch die Feder 17 bewirkten Teilkraft verschwenkt. Das Rastelement 16 gelangt über die Rastnase 15 hinweg und rastet ein. Wird der Flügel 2 nun losgelassen, so wird der Gleiter 7 durch den Türschließer 4 in Richtung von der Feststellvorrichtung 8 weg - in der Fig. 3 nach rechts - beaufschlagt. Das Rastelement 16 gelangt in Anlage mit der Schräge 25 der Rastnase 15, wobei die Schräge 25 steiler als die dem Gleiter 7 zugewandte Schräge 24 ausgebildet ist, so dass ein höhere Kraft erforderlich ist, um den Rastkopf 14 zu verschwenken und das Rastelement 16 und somit den Gleiter 7 freizugeben. Diese durch die Stellschraube 19 einstellbare Haltekraft wird so eingestellt, dass die durch den Türschließer 4 erzeugte Schließkraft nicht ausrecht, den Rastkopf 14 zu verschwenken und den Gleiter 7 freizugeben. Wird die auf die Schräge 25 des Rastkopfs 14 einwirkende Kraft durch eine zusätzliche manuelle Betätigung des Flügels 2 in Schließrichtung erhöht, so wird der Rastkopf 14 verschwenkt und das Rastelement 16 frei. Der Türschließer 4 kann den Flügel 2 weiter in Richtung seiner Schließlage führen.If the wing 2 of the revolving door 1 is opened manually, then the slider 7, depending on the positioning of the locking device 8 in the slide rail 5, in the region of the locking device 8, wherein first the locking element 16 in abutment with the latching element 16 facing slope 24th arrives. If the wing 2 further opened, the locking head 14 is pivoted by the locking element 16 against the force caused by the spring 17 partial force. The locking element 16 passes over the locking lug 15 and engages. If the wing 2 is now released, then the slider 7 through the door closer 4 in the direction of the locking device 8 away - in the Fig. 3 to the right - charged. The locking element 16 comes into abutment with the bevel 25 of the locking lug 15, wherein the slope 25 is steeper than the slide 7 facing slope 24 is formed so that a higher force is required to pivot the locking head 14 and the locking element 16 and thus to release the slider 7. This adjustable by the screw 19 holding force is adjusted so that the closing force generated by the door closer 4 is not sufficient to pivot the locking head 14 and release the slider 7. If the force acting on the bevel 25 of the latching head 14 is increased by an additional manual actuation of the blade 2 in the closing direction, the latching head 14 is pivoted and the latching element 16 is released. The door closer 4 can continue to guide the wing 2 in the direction of its closed position.

Durch diese Anordnung weist die Feststellvorrichtung 8 vorteilhaft eine besonders niedrige Bauhöhe und eine kurze Baulänge auf. Dadurch ist ein größerer maximaler Türöffnungswinkel möglich, und die Gleitschiene 5 kann niedrig gehalten werden, was beim integrierten Einbau in den Flügel 2 oder den Rahmen 3 vorteilhaft ist.By this arrangement, the locking device 8 advantageously has a particularly low height and a short overall length. As a result, a larger maximum door opening angle is possible, and the slide 5 can be kept low, which is advantageous in the integrated installation in the wing 2 or the frame 3.
