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.

Die DE 697 16 368 T2 offenbart eine Vorrichtung zum Offenhalten einer Tür, mit einer innerhalb einer Gleitschiene angeordneten Rückhalteeinheit. Die Rückhalteeinheit ist in einer Kammer außerhalb der Bewegungsbahn des Gleiters angeordnet und weist einen federbelasteten Hebel auf, der in die Bewegungsbahn des Gleiters eingreift. Der in der Gleitschiene geführter Gleiter kann auf den Hebel auflaufen und ist aufgrund der Reibkräfte zwischen Gleiter und Hebel festsetzbar. Eine Anordnung der Rückhalteeinheit in der Bewegungsbahn des Gleiters für kleine, niedrige Gleitschienen ist nicht möglich. Eine Dämpfungseinrichtung ist nicht vorhanden.The DE 697 16 368 T2 discloses a device for holding a door open, with a retaining unit disposed within a slide rail. The retaining unit is arranged in a chamber outside the movement path of the slider and has a spring-loaded lever which engages in the movement path of the slider. The guided in the slide rail can run on the lever and can be fixed due to the friction between the slider and lever. An arrangement of the retaining unit in the path of movement of the slider for small, low slide is not possible. A damping device is not available.

Die EP 1 707 722 A1 betrifft eine Feststellvorrichtung für Türflügel mit einem Türschließer, wobei ein Gleitstück zusammen mit einem an einer Führungsschiene festlegbaren Widerlager die Feststellvorrichtung bildet und das Widerlager ein überschiebbares, selbsttätig nachgebend und rückstellendes Halteglied aufweist. Das Halteglied ist eine von einer Rückstellfeder vertikal beaufschlagte Kugel, die in eine Ausnehmung eines am Gleitstück angeordneten Gleitstückadapters eingreift. Die Feststellvorrichtung weist keine Dämpfungseinrichtung auf.The EP 1 707 722 A1 concerns a locking device for door leaf with a door closer, wherein a slider together with a fixable to a guide rail abutment forms the locking device and the abutment has a pushable, automatically yielding and restoring retaining member. The holding member is a vertically acted upon by a return spring ball which engages in a recess of a slider arranged on the slider adapter. The locking device has no damping device.

Aus der DE 694 07 140 T2 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. Am Gleiter ist ein Fortsatz mit einem Rasthaken angeordnet, welcher zur Feststellung des Flügels in einer Offenstellung mit einer an der Feststellvorrichtung angeordneten, mit zwei Federn beaufschlagten Wippe zusammenwirkt, wobei die beiden Federn eine Dämpfung der Bewegung des Gleiters in der Feststellvorrichtung bewirken.From the DE 694 07 140 T2 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. On the slider, an extension is arranged with a latching hook, which cooperates to determine the wing in an open position with a arranged on the locking device, acted upon by two springs rocker, wherein the two springs cause a damping of the movement of the slider in the locking device.

Die Anordnung benötigt einen großen Einbauraum und damit eine große Gleitschiene. Aufgrund der großen Baulänge der Feststellvorrichtung ist nur eine begrenzte Öffnungsweite des Türflügels möglich. Der Öffnungswinkel ist nicht einstellbar.The arrangement requires a large installation space and thus a large slide rail. Due to the large length of the locking device only a limited opening width of the door is possible. The opening angle is not adjustable.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zur Feststellung eines Flügels einer Tür mit einer Dämpfung der Flügelbewegung auszubilden, welche einen geringen Einbauraum benötigt.The invention has for its object to form a device for detecting a wing of a door with a damping of the wing movement, 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.

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 auf, welcher in das C-förmige Profil der Gleitschiene einschiebbar ist, und an dem die weiteren Teile der Feststellvorrichtung angeordnet sind. 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. Neben der Feststellung ist eine Dämpfung der Bewegung des Gleiters in der Feststellvorrichtung vorgesehen.The particularly compact, locking device according to the invention therefore has a carriage which is inserted into the C-shaped profile of the slide, and on which the other parts of the locking device are arranged. 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. In addition to the determination of a damping of the movement of the slider is provided in the locking device.

Dazu ist ein Federelement, welches vorteilhaft als Elastomerelement ausgebildet ist, vorgesehen, das im schwenkbar am Schlitten gelagerten Rasthebel angeordnet ist. Der Rasthebel weist einen Rastfortsatz auf, der mit einem am Gleiter angeordneten Rastelement zur Feststellung des Gleiters zusammenwirkt. Neben dem Rastfortsatz ist am Gleiter ein weiterer Fortsatz vorgesehen, der über den Rastfortsatz hinausragt und mit dem Elastomerelement zur Dämpfung der Gleiterbewegung zusammenwirkt. Vorteilhaft vereint das nur eine Elastomerelement dabei zwei Funktionen in sich. Dies ist zum Einen die Dämpfung der Gleiterbewegung und zum Anderen die Abstützung des Rasthebels der Feststellvorrichtung.For this purpose, a spring element, which is advantageously designed as an elastomer element, is provided, which is arranged in the pivotally mounted on the carriage locking lever. The detent lever has a latching extension, which cooperates with a arranged on the slider latching element for detecting the slider. In addition to the latching extension, another extension is provided on the slider, which protrudes beyond the latching extension and cooperates with the elastomer element for damping the slider movement. Advantageously, this unites only one elastomer element while two functions in itself. On the one hand this is the damping of the slider movement and on the other hand the support of the locking lever of the locking device.

Die Vorspannung des Elastomerelements lässt sich mit einer längs eines Langlochs verstellbaren Einstellschraube einstellen, wobei das Elastomerelement gequetscht wird und sich dadurch stärker an der Basis der C-förmigen Gleitschiene abstützt. Damit wird die Kraft auf den schwenkbaren Rasthebel und damit die Haltekraft der Feststellvorrichtung erhöht. Gleichzeitig erhöht sich die Festigkeit des Elastomerelements, so dass eine stärkere Dämpfung der durch den Fortsatz des Gleiters auf das Elastomerelement übertragenen Bewegung des Gleiters erfolgt. Vorteilhaft ist damit die Anpassung der Haltekraft der Feststellvorrichtung und gleichzeitig der Dämpfung der Gleiterbewegung mit nur einer Einstellschraube möglich. Eine, beispielsweise durch einen breiten und/oder schweren Flügel einer Tür erforderliche, höhere Haltekraft und Dämpfung ist somit schnell und einfach einstellbar.The bias of the elastomeric element can be adjusted with an adjusting screw which can be adjusted along a slot, whereby the elastomeric element is squeezed is and thereby supported more strongly at the base of the C-shaped slide. Thus, the force on the pivotable locking lever and thus the holding force of the locking device is increased. At the same time, the strength of the elastomeric element increases, so that a stronger damping of the transmitted by the extension of the slider on the elastomeric element movement of the slider takes place. Advantageously, the adjustment of the holding force of the locking device and at the same time the damping of the slider movement with only one adjustment screw is possible. A, required for example by a wide and / or heavy wing of a door, higher holding force and damping is thus quickly and easily adjustable.

Um einen ausreichenden Weg zur Dämpfung des Gleiters zu schaffen, sind der zur Feststellung zusammenwirkende Rastfortsatz des Rasthebels und das Rastelement des Gleiters so ausgebildet, dass sich diese über einen Bereich überlappen können.In order to provide a sufficient way to damp the slider, cooperating to determine locking projection of the locking lever and the locking element of the slider are designed so that they can overlap over a range.

Weiterhin ist am Rastelement eine Rastnase mit zwei Schrägen vorgesehen, welche vorteilhaft unterschiedlich steil ausgebildet sind. Die der Feststellvorrichtung zugewandte Schräge ist flacher ausgebildet, wodurch ein leichteres Aufgleiten des am Rastfortsatz angeordneten Rasthakens erfolgt und damit das Einrasten des Rastelements des Gleiters in die Feststellvorrichtung erleichtert ist. Demgegenüber ist die gegenüberliegende Schräge an der Rastnase steiler ausgebildet, wodurch ein sicherer Halt des durch den Türschließer beaufschlagten Gleiters in der Feststellvorrichtung bewirkt ist.Furthermore, a detent with two bevels is provided on the locking element, which are advantageously formed differently steep. The bevel facing the locking device is flatter, whereby a lighter sliding of the locking projection is arranged on the latching hook and thus the engagement of the locking element of the slider is facilitated in the locking device. In contrast, the opposite slope is steeper formed on the locking lug, whereby a secure hold of the acted upon by the door closer slider is effected in the locking device.

Wird der Flügel der Tür zusätzlich manuell in Schließrichtung betätigt, so wird der Rastfortsatz durch das Rastelement entlang der Schräge an der Rastnase angehoben, und der Gleiter wird frei. Der Flügel kann durch den Türschließer weiter in seine Schließlage geführt werden.If the wing of the door is additionally actuated manually in the closing direction, the latching extension is raised by the latching element along the bevel on the latching lug, and the slider is released. The wing can be guided by the door closer into its closed position.

In der Gleitschiene 5 ist weiterhin eine Feststellvorrichtung 8 angeordnet, mit der es möglich ist, den Flügel 2 der Drehtür 1 in einer Offenstellung zu halten.In Fig. 1 a revolving door 1 with a wing 2 and a frame 3 is shown. On the wing 2, a door closer 4 is arranged, which is arranged here integrated in the wing 2. On the frame 3 of the revolving door 1, a slide 5 is arranged, which is integrated here in the frame. On a rotatable shaft of the door closer 4, a sliding arm 6 is arranged, wherein an end facing away from the door closer 4 pivotally mounted slider 7 is guided in the slide rail 5. In the slide 5 a locking device 8 is further arranged, with which it is possible to keep the wing 2 of the revolving door 1 in an open position.

Fig. 2 und Fig. 3 zeigen die Anordnung der Feststellvorrichtung 8 in der Gleitschiene 5, wobei der Flügel 2 in seiner Offenstellung gehalten ist, indem der Gleiter 7 mit der Feststellvorrichtung 8 in Eingriff steht. 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 the 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.

Die Feststellvorrichtung 8 weist einen Schlitten 9 auf, welcher in dem C-förmigen Profil der Gleitschiene 5 längsverschiebbar geführt ist. Zur Festlegung der Position der Feststellvorrichtung 8 innerhalb der Gleitschiene 5 ist am Schlitten 9 ein Befestigungselement 10, 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, which is guided longitudinally displaceable in the C-shaped profile of the slide rail 5. To determine the position the locking device 8 within the slide rail 5 is on the carriage 9, a fastener 10, which is designed here as a threaded pin with hexagon socket 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 in einem Drehlager 11 am Schlitten 9 einerends gelagerten, schwenkbaren Rasthebel 12 auf, an welchem ein Rastfortsatz 13 mit einem Rasthaken 14 ausgebildet ist. Der Rasthaken 14 wirkt mit einem am Gleiter 7 angeordneten Rastelement 15 zur Feststellung des Flügels 2 in der vorgesehenen Offenstellung zusammen. Weiterhin weist der Rasthebel 12 Anschläge 23 auf, welche den Rasthebel 12 in der Gleitschiene 5 führen und halten, wodurch ein Ausschwenken des Rasthebels 12 aus der Gleitschiene 5 heraus verhindert ist.The locking device 8 further comprises a pivot bearing 11 mounted on the slide 9 at one end, in a pivot bearing 11, on which a latching extension 13 is formed with a latching hook 14. The latching hook 14 cooperates with a arranged on the slider 7 locking element 15 for detecting the wing 2 in the intended open position together. Furthermore, the locking lever 12 stops 23, which guide the latching lever 12 in the slide 5 and hold, whereby a pivoting of the locking lever 12 is prevented from the slide 5 out.

In dem ausgesparten Rasthebel 12 ist ein Federelement angeordnet, das als Elastomerelement 16 ausgebildet ist. Das Elastomerelement 16 stützt den Rasthebel 12 an der Basis der Gleitschiene 5 - in der Fig. 3 nach oben - ab. Im Rasthebel 12 ist ein Langloch 17 vorgesehen, das von einer Schraube 25 durchgriffen ist, welche in eine Mutter 26 eingreift. Die Schraube 25 und die Mutter 26 bilden ein Einstellelement 18. Durch Verschieben des Einstellelements 18 längs des Langlochs 17 ist die Vorspannung des Elastomerelements 16, das sich innerhalb des Rasthebels 12 an einer zurückspringenden Wandung 27 des Rastfortsatzes 13 und gegen die Basis der Gleitschiene 5 abstützt, veränderbar, wodurch die Haltekraft der Feststellvorrichtung 8 und die Dämpfung der Bewegung des Gleiters 7 gleichzeitig einstellbar sind. Dies ist vorteilhaft, da beispielsweise ein schwerer Flügel 2 sowohl eine größere Haltekraft als auch eine höhere Dämpfung der Öffnungsbewegung erfordert. Bei der erfindungsgemäßen Feststellvorrichtung 8 ist die Dämpfung und die Feststellkraft gemeinsam durch Verschieben des nur einen Einstellelements 18 entlang des Langlochs 17 einstellbar.In the recessed latching lever 12, a spring element is arranged, which is designed as an elastomeric element 16. The elastomeric element 16 supports the locking lever 12 at the base of the slide rail 5 - in the Fig. 3 upwards - down. In the locking lever 12, a slot 17 is provided, which is penetrated by a screw 25 which engages in a nut 26. By screwing the adjusting member 18 along the slot 17, the bias of the elastomeric element 16, which is supported within the locking lever 12 on a recessed wall 27 of the latching extension 13 and against the base of the slide rail 5 , changeable, whereby the holding force of the locking device 8 and the damping of the movement of the slider 7 are simultaneously adjustable. This is advantageous since, for example, a heavy wing 2 requires both a greater holding force and a higher damping of the opening movement. In the locking device 8 according to the invention the damping and the locking force is adjustable together by moving the only one adjustment member 18 along the slot 17.

Zur Dämpfung der Gleiterbewegung ist am Gleiter 7 ein Fortsatz 24 ausgebildet, der nach dem Einrasten des Gleiters 7 in der Feststellvorrichtung 8 an dem Elastomerelement 16 anliegt, das die weitere Bewegung des Gleiters 7 dämpft. Die Länge des Fortsatzes 24 ist dabei abhängig von der Elastizität des Elastomerelements 16 in nicht vorgespanntem Zustand zu wählen. Der Rastfortsatz 13 und das Rastelement 15 sind, um die Dämpfungsbewegung auszugleichen, so ausgebildet, dass das Rastelement 15 den Rastfortsatz 13 über einen bestimmten Bereich hinweg unterfahren kann, wie es in der Figur 3 gezeigt ist. Der maximal mögliche Dämpfungsweg kann dabei durch die Länge des Rasfortsatzes 13 und des Rastelements 15 bestimmt werden.To damp the slider movement, an extension 24 is formed on the slider 7, which after the engagement of the slider 7 in the locking device 8 on the Elastomer element 16 rests, which dampens the further movement of the slider 7. The length of the extension 24 is dependent on the elasticity of the elastomeric element 16 to select in non-biased state. The latching extension 13 and the latching element 15 are, in order to compensate for the damping movement, designed so that the latching element 15 can pass under the latching extension 13 over a certain range, as in the FIG. 3 is shown. The maximum possible damping path can be determined by the length of the Rasfortsatzes 13 and the locking element 15.

Der Gleiter 7 ist mittels eines Verbindungselements 22 drehgelenkig mit dem Gleitarm 6 des Türschließers 4 verbunden und weist am Rastelement 15 eine Rastnase 19 mit zwei Schrägen 20, 21 auf, wie es in der Fig. 7 gezeigt ist. Die von dem Gleiter 7 weg gerichtete, der Feststellvorrichtung 8 zugewandte Schräge 20 ist dabei flacher ausgebildet, als die gegenüberliegende Schräge 21, wodurch das Einrasten den Gleiters 7 in die Feststellvorrichtung 8 erleichtert ist.The slider 7 is pivotally connected by means of a connecting element 22 with the sliding arm 6 of the door closer 4 and has on the locking element 15 a latching lug 19 with two bevels 20, 21, as shown in FIG. The facing away from the slider 7, the locking device 8 facing slope 20 is formed flatter than the opposite slope 21, whereby the engagement of the slider 7 is facilitated in the locking device 8.

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 15 mit seiner an der Rastnase 19 ausgebildeten Schräge 20 in Anlage mit dem Rasthaken 14 des Rasthebels 12 kommt. Wird der Flügel 2 weiter geöffnet, gleitet der Rasthaken 14 an der Schräge 20 auf, wodurch der Rastfortsatz 13 und der Rasthebel 12 entgegen der Kraft des Elastomerelements 16 angehoben wird. Der Rasthaken 14 gelangt über die Rastnase 19 hinweg und rastet hinter der Rastnase 19 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. Der Rasthaken 14 gelangt in Anlage mit der Schräge 21 der Rastnase 15. Da die Schräge 21 steiler als die der Feststellvorrichtung 8 zugewandte Schräge 20 ausgebildet ist, ist eine höhere Kraft erforderlich, um den Rasthaken 14 zur Freigabe von Rastelement 15 und Gleiter 7 anzuheben.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 15 with its formed on the locking lug 19 20 slope Appendix comes with the latching hook 14 of the locking lever 12. If the wing 2 further opened, the latching hook 14 slides on the slope 20, whereby the latching projection 13 and the latching lever 12 is raised against the force of the elastomeric element 16. The latching hook 14 passes over the latching lug 19 and engages behind the latching lug 19. 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. Since the bevel 21 is steeper than that of the locking device 8 facing slope 20 is formed, a higher force is required to lift the latching hook 14 to release latching element 15 and slider 7.

Diese durch das Einstellelement 18 einstellbare Haltekraft wird so eingestellt, dass die durch den Türschließer 4 erzeugte Schließkraft nicht ausreicht, den Rasthaken 14 anzuheben und den Gleiter 7 freizugeben. Wird die auf die Schräge 21 der Rastnase 19 wirkende Kraft durch eine zusätzliche manuelle Betätigung des Flügels 2 in Schließrichtung erhöht, so wird der Rasthaken 14 entlang der Schräge 21 angehoben und das Rastelement 15 des Gleiters 7 frei. Der Türschließer 4 kann den Flügel 2 weiter in Richtung seiner Schließlage führen.This adjustable by the adjusting member 18 holding force is adjusted so that the closing force generated by the door closer 4 is insufficient, the Raise latching hook 14 and release the slider 7. If the force acting on the bevel 21 of the latching lug 19 is increased by an additional manual actuation of the wing 2 in the closing direction, the latching hook 14 is raised along the slope 21 and the latching element 15 of the slider 7 becomes free. The door closer 4 can continue to guide the wing 2 in the direction of its closed position.

Durch diese Anordnung, insbesondere die Anordnung des Elastomerelements 16 im Rasthebel 12, 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, in particular the arrangement of the elastomeric element 16 in the locking lever 12, the locking device 8 advantageously has a particularly low overall 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.
