Definitions
- the invention relates to an overhead door closer in which a door closer arm is guided in a slide rail on the door frame side by means of a slide piece articulated to the door closer arm and a mechanical device which can be set up is provided for limiting the guide region of the slide rail for the slide piece in the slide rail.
- Such a door closer is known from the company publication "GEZE door closer", printed note 9.89. It is an overhead gear door closer with a slide rail with the designation T 5000.
- the opening angle at which the open door can be locked can be adjusted continuously between 80 ° and 130 ° via a mechanical lock.
- a locking device for door leaves with a door closer is known, the closer shaft of which is coupled to one end of an actuating arm, the other end engages via a slide in a guide rail which is assigned a holding unit which defines the slide in a certain open position.
- the holding unit has a locking knob which is loaded by a spring element in the locking direction and engages on the sliding piece.
- Such a locking device extends essentially transversely to the direction of displacement of the slider and can not be accommodated in the known guide rails because of the size. Such a locking device can be pushed over to completely open a door.
- the invention has for its object to provide a simple mechanical locking device for an overhead door closer of the type mentioned, which can be put in place from the outside and re-established.
- the locking devices are arranged in this door closer according to the invention in the slider and therefore do not take up any additional volume. It exists the possibility of overriding these locking devices, which fix the associated doors at a certain opening angle, so that the doors can be fully opened, for example. In a simple manner, it is also possible to switch on the locking devices again.
- a preferred embodiment of the door closer is specified in claim 3.
- the non-round rod is rotated by moving the associated sliding sleeve when the twisted transition piece is passed over. Due to the changing outer diameter, the respective blocking element is therefore displaced in the transverse direction of the slide rail and, together with a locking element on the rail side or directly with a slide rail wall, forms the mechanical locking device.
- the locking device can be set up in the longitudinal direction of the slide rail according to claim 8 by moving the locking element or by an adjustable attachment on the rotatable rod according to claim 9.
- the locking device can also be designed according to claims 12 and 13 according to the principle of a slip clutch in order to avoid overloading the door closer or its correspondingly loaded parts in the event of an overload on the door closer arm.
- FIGS. 1-6 the door closer arm 2, which is articulated to the gearbox accommodated in the housing and which is guided with its end in the slide rail 3 to be fastened on the door frame side, can be seen.
- the corresponding end of the door closer arm 2 is connected in an articulated manner to a slide piece 4, which is guided in the slide rail 3, which is C-shaped in cross section and open at the bottom.
- a rod 5 with a square cross section is guided with little play and is rotatably supported at its ends in the end plugs 32 and 33 of the slide rail 3.
- the diameter of the bore 41 corresponds approximately to the diagonal of the cross section of the rod 5.
- this rod 5 has a transition piece 51 twisted by 45 °.
- a sliding sleeve 6 is positively placed on the rod 5 with a corresponding bore and can be moved in the axial direction from the outside via the grip element 61. If this sliding sleeve 6 passes over the transition piece 51, the rod 5 is rotated in each case by 45 °.
- a locking device described below is actuated by this displacement of the sliding sleeve 6 or the resulting rotation of the rod 5.
- a chamber 42 is provided, which is open towards the top of the slide rail wall 31 and in which a plate-like blocking element 8, preferably made of plastic, is accommodated in a form-fitting manner but radially to the axis of rotation of the non-circular rod 5.
- This blocking element 8 rests on the non-circular rod 5, which is preferably square in cross section.
- a locking element 7 projecting slightly into the slide rail 3 is provided in a slot 311 which can be displaced in the longitudinal direction of the slide rail.

Description
Die Erfindung betrifft einen obenliegenden Türschließer, bei dem ein Türschließerarm mit Hilfe eines mit dem Türschließerarm gelenkig verbundenen Gleitstückes in einer türzargenseitigen Gleitschiene geführt und zur Begrenzung des Führungsbereiches der Gleitschiene für das Gleitstück in der Gleitschiene eine einrichtbare mechanische Vorrichtung vorgesehen ist.The invention relates to an overhead door closer in which a door closer arm is guided in a slide rail on the door frame side by means of a slide piece articulated to the door closer arm and a mechanical device which can be set up is provided for limiting the guide region of the slide rail for the slide piece in the slide rail.
Ein solcher Türschließer ist aus der Firmenschrift "GEZE Türschließer", Druckvermerk 9.89 bekannt. Es handelt sich dabei um einen obenliegenden Zahntriebtürschließer mit einer Gleitschiene mit der Bezeichnung T 5000. Über eine mechanische Feststellung läßt sich der Öffnungswinkel, in dem die geöffnete Tür feststellbar ist, stufenlos zwischen 80° und 130° einstellen.Such a door closer is known from the company publication "GEZE door closer", printed note 9.89. It is an overhead gear door closer with a slide rail with the designation T 5000. The opening angle at which the open door can be locked can be adjusted continuously between 80 ° and 130 ° via a mechanical lock.
In der Praxis stellt sich die Forderung, Türen mit derartigen Türschließern und eingerichteten Feststellwinkeln in bestimmten Situationen auch vollständig öffnen zu können. Bei dem bekannten Türschließer ist eine solche vollständige Öffnung bzw. Schließung nur durch Überdrücken einer Keilbremse möglich.In practice, there is a requirement to be able to fully open doors with such door closers and locking brackets in certain situations. In the known door closer, such a complete opening or closing is only possible by overpressing a wedge brake.
Aus der DE-A-3604083 ist eine Feststellvorrichtung für Türflügel mit einem Türschließer bekannt, dessen Schließerwelle mit einem Ende eines Betätigungsarmes gekuppelt ist, dessen anderes Ende über ein Gleitstück in eine Führungsschiene eingreift, der eine das Gleitstück in bestimmter Offenstellung festlegende Halteeinheit zugeordnet ist. Dabei weist die Halteeinheit einen durch ein Federglied im Sperrsinn belasteten, am Gleitstück eingreifenden Rastnoppen auf. Eine solche Feststellvorrichtung erstreckt sich im wesentlichen quer zur Verschieberichtung des Gleitstückes und läßt sich in den bekannten Führungsschienen wegen der Baugröße nicht unterbringen. Zur vollständigen Öffnung einer Tür ist eine solche Feststellvorrichtung überdrückbar.From DE-A-3604083 a locking device for door leaves with a door closer is known, the closer shaft of which is coupled to one end of an actuating arm, the other end engages via a slide in a guide rail which is assigned a holding unit which defines the slide in a certain open position. In this case, the holding unit has a locking knob which is loaded by a spring element in the locking direction and engages on the sliding piece. Such a locking device extends essentially transversely to the direction of displacement of the slider and can not be accommodated in the known guide rails because of the size. Such a locking device can be pushed over to completely open a door.
Der Erfindung liegt die Aufgabe zugrunde, bei einem obenliegenden Türschließer der eingangs genannten Art eine einfache mechanische Feststellvorrichtung vorzuschlagen, die von außen in Kraft gesetzt und wieder eingerichtet werden kann.The invention has for its object to provide a simple mechanical locking device for an overhead door closer of the type mentioned, which can be put in place from the outside and re-established.
Diese Aufgabe wird bei einem obenliegenden Türschließer im Zusammenwirken der Merkmale des Anspruches 1 oder 2 gelöst.This object is achieved in an overhead door closer in cooperation with the features of
Die Feststellvorrichtungen sind bei diesen erfindungsgemäßen Türschließern im Gleitstück angeordnet und beanspruchen daher kein zusätzliches Bauvolumen. Es besteht die Möglichkeit, diese Feststellvorrichtungen, die die zugehörigen Türen bei einem bestimmten Öffnungswinkel feststellen, außer Kraft zu setzen, sodaß die Türen beispielsweise vollständig geöffnet werden können. Auf einfache Weise ist es möglich, die Feststellvorrichtungen auch wieder zuzuschalten.The locking devices are arranged in this door closer according to the invention in the slider and therefore do not take up any additional volume. It exists the possibility of overriding these locking devices, which fix the associated doors at a certain opening angle, so that the doors can be fully opened, for example. In a simple manner, it is also possible to switch on the locking devices again.
Eine bevorzugte Ausgestaltung des Türschließers wird mit Anspruch 3 angegeben. Über die Verschiebung der zugehörigen Schiebehülse wird beim Überfahren des verdrillten Übergangsstückes die unrunde Stange verdreht. Auf Grund des sich ändernden Außendurchmessers wird daher das jeweilige Blockierungselement in Querrichtung der Gleitschiene verschoben und bildet zusammen mit einem schienenseitigen Arretierungselement oder direkt mit einer Gleitschienenwandung die mechanische Feststellvorrichtung.A preferred embodiment of the door closer is specified in
Eine Einrichtung der Feststellvorrichtung in Längsrichtung der Gleitschiene kann gemäß Anspruch 8 durch die Verschiebung des Arretierungselementes oder durch einen einrichtbaren Aufsatz an der verdrehbaren Stange gemäß Anspruch 9 erfolgen.The locking device can be set up in the longitudinal direction of the slide rail according to
Die Feststellvorrichtung kann auch gemäß den Ansprüchen 12 und 13 nach dem Prinzip einer Rutschkupplung ausgebildet werden, um bei Überlast auf den Türschließerarm eine Überbeanspruchung des Türschließers bzw. seiner entsprechend belasteten Teile zu vermeiden.The locking device can also be designed according to claims 12 and 13 according to the principle of a slip clutch in order to avoid overloading the door closer or its correspondingly loaded parts in the event of an overload on the door closer arm.

Zunächst wird auf die Figuren 1 - 6 Bezug genommen. An dem in Fig. 1 erkennbaren Türschließer bzw. dessen Gehäuse 1 ist der gelenkig mit dem im Gehäuse aufgenommenen Getriebe verbundene Türschließerarm 2 erkennbar, der in der türzargenseitig zu befestigenden Gleitschiene 3 mit seinem Ende geführt ist. Wie Fig. 2 zeigt, ist das entsprechende Ende des Türschließerarmes 2 gelenkig mit einem Gleitstück 4 verbunden, welches in der im Querschnitt C-förmigen, nach unten offenen Gleitschiene 3 geführt. Durch die in Fig. 5 erkennbare zylindrische Bohrung 41 des Gleitstückes 4 hindurch ist mit geringem Spiel eine im Querschnitt quadratische Stange 5 geführt, die an ihren Enden in den Endstopfen 32 und 33 der Gleitschiene 3 drehbar gelagert ist. Der Durchmesser der Bohrung 41 entspricht dabei etwa der Diagonale des Querschnittes der Stange 5.First, reference is made to FIGS. 1-6. 1, the door
An einem Ende weist diese Stange 5 ein um 45° verdrilltes Übergangsstück 51 auf. Eine Schiebehülse 6 ist mit einer entsprechenden Bohrung formschlüssig auf die Stange 5 aufgesetzt und in axialer Richtung von außen über das Griffelement 61 verschiebbar. Überfährt diese Schiebehülse 6 das Übergangsstück 51, So wird die Stange 5 jeweils um 45° verdreht. Durch diese Verschiebung der Schiebehülse 6 bzw. die sich ergebende Verdrehung der Stange 5 wird eine nachfolgend beschriebene Feststellvorrichtung betätigt.At one end, this
Im Gleitstück 4 ist in eine nach oben zur Gleitschienenwandung 31 hin offene Kammer 42 vorgesehen, in der formschlüssig, jedoch radial zur Drehachse der unrunden Stange 5 verschiebbar ein plattenartiges Blockierungselement 8 vorzugsweise aus Kunststoff aufgenommen ist. Dieses Blockierungselement 8 ruht auf der unrunden, vorzugsweise im Querschnitt quadratischen Stange 5. Beim Verdrehen der Stange 5 wird also dieses Blockierungselement 8 angehoben bzw. abgesenkt. In einem Schlitz 311 in Längsrichtung der Gleitschiene verschiebbar ist ein geringfügig in die Gleitschiene 3 hineinragendes Arretierungselement 7 vorgesehen. Bei entsprechender Verschiebung des Türschließerarmes 2 bzw. des daran angelenkten Gleitstückes 4 schiebt sich bei entsprechender Bemessung das in Fig. 3 dargestellte angehobene Blockierungselement 8 am Ende eines zu begrenzenden Führungsbereiches des Gleitstückes 4 gegen das Arretierungselement 7 und setzt sich daran fest. Der entstandene Reibschluß reicht aus, um die entsprechend geöffnete, nicht dargestellte Tür in der zugehörigen Öffnungslage festzusetzen. Durch Überwindung des Reibschlusses kann die Tür wieder in Schließrichtung gedrückt werden, wobei sich das Blockierungselement 8 vom Arretierungselement 7 löst.In the
Durch Verschiebung der Schiebehülse 6 aus der Position in Fig. 3 in die Position entsprechend Fig. 2, wobei sie das Übergangsstück 51 überfahren hat, wird die Stange 6 verdreht. Das Blockierungselement 8 ruht dann nicht mehr auf einer Kante der Stange sondern auf einer Flachseite und senkt sich ab. Damit ist die Feststellvorrichtung außer Kraft gesetzt. Das Gleitstück 4 kann ohne Berührung unter dem Arretierungselement 7 verschoben werden. Durch entsprechende Verschiebung der Schiebehülse 6 läßt sich die Feststellvorrichtung wieder aktivieren.By moving the sliding
Beim Ausführungsbeispiel nach den Figuren 7 - 10 ist lediglich die Einrichtung der Feststellvorrichtung geändert. Ihre Inkraftsetzung erfolgt in der gleichen Weise über die Verschiebung der Schiebehülse 6 und die damit verbundene Verdrehung der Stange 5. Auf dieser Stange mit dem endseitigen um 45° verdrillten Übergangsstück 51 ist in Achsrichtung einrichtbar ein Aufsatz 52 mit unrundem Querschnitt, vorzugsweise wiederum quadratisch, aufgesetzt. Seine Befestigung erfolgt beispielsweise mit zwei Klemmschrauben 53. Durch Verdrehung der Stange 5 wirkt bei entsprechendem Eingriff in das Gleitstück 104 durch die Bohrung 141 der Aufsatz 52 mit seinem Mantel gegen das im Gleitstück 104 in der nach oben offenen Kammer 142 formschlüssig aufgenommene, plattenartige Blockierungselement 108, welches wiederum vorzugsweise aus Kunststoff oder Gummi besteht. In der in den Figuren 8 und 10 dargestellten Feststellungsposition, die dem entsprechenden Feststellwinkel der geöffneten zugehörigen Tür entspricht, greift eine Kante des Aufsatzes 52 in die Kammer 142 hinein und drückt dabei am Ende eines zu begrenzenden Führungsbereiches des Gleitstücks 104 das Blockierungselement 108 klemmend gegen die Innenseite der oberen Gleitschienenwandung 131 der Gleitschiene 103, sodaß das Gleitstück 104 und damit auch der daran angebundene Türschließerarm festgesetzt ist. Durch Verdrehen der Stange 5 in die in den Figuren 7 und 9 dargestellten Position ist die Feststellvorrichtung außer Kraft.In the exemplary embodiment according to FIGS. 7-10, only the device of the locking device is changed. They come into effect in the same way via the displacement of the sliding
