Description

Die Erfindung bezieht sich auf eine Profillaufschiene mit den Merkmalen des Oberbegriffes des Anspruches 1.The invention relates to a profile track with the features of the preamble of claim 1.

Eine derartige Profillaufschiene findet für Antriebsgeräte Verwendung, bei denen ein von einem Antriebsmotoraggregat hin- und hergehend angetriebenes Schleppglied entlang der Laufschiene geführt ist, insbesondere in Form einer Endlos-Kette, an deren eines Trums ein längs der Laufschiene geführtes Schlittenteil angekoppelt ist. Das Schlittenteil steht mit dem Torblatt in Verbindung, beispielsweise dem Blatt eines Überkopftores, und muss entsprechend der Höhe des Torblattes über eine entsprechend grosse Strecke hinweg bewegt werden können. Bei hohen Toren werden entsprechende Verschiebewege und damit lange Laufschienen erforderlich.Such a profile track is used for drive devices in which a towing member driven to and fro by a drive motor unit is guided along the track, in particular in the form of an endless chain, to the one strand of which a slide part guided along the track is coupled. The slide part is connected to the door leaf, for example the leaf of an overhead door, and must be able to be moved over a correspondingly large distance in accordance with the height of the door leaf. Appropriate displacement paths and therefore long running tracks are required for tall gates.

Da man im Sinne einer einfachen Ausbildung und Montage in der Regel davon absieht, die Laufschiene zwischen ihren beiden Endbereichen zusätzlich ortsfest zu arretieren, wird die Laufschiene angesichts der an ihr auftretenden Kräfte erheblichen Biegebeanspruchungen unterworfen. Andererseits soll eine solche Schiene natürlich möglichst wenig aufwendig, leicht und in der Einbaulage hinsichtlich des eingenommenen Raumes sparsam ausgebildet sein.Since, in the sense of simple training and assembly, one generally refrains from locking the running rail between its two end regions in a stationary manner, the running rail is subjected to considerable bending stresses in view of the forces occurring on it. On the other hand, such a rail should, of course, be designed to be as inexpensive, light and economical as possible in terms of the space occupied in the installed position.

Aufgrund der insbesondere über das Schlittenteil in die Schiene eingeleiteten Kräfte wird diese nicht nur auf Durchbiegung in einer Richtung beansprucht, sondern auch in Richtungen quer dazu, so dass sich auch Kraftkomponenten ergeben, die in Richtung einer Verdrehung auf die Schiene einwirken. Die an der Schiene auftretenden Verformungen beeinträchtigen wieder die Güte der Führung des Schlittenteiles an der Schiene, wodurch die in die Schiene eingeleiteten Verformungskräfte noch grösser werden. Dies kann jedenfalls dazu führen, dass der Torantrieb unnötig schwergängig und verschleissbehaftet arbeitet.Due to the forces introduced into the rail in particular via the slide part, this is not only subjected to deflection in one direction, but also in directions transverse to it, so that force components also result which act on the rail in the direction of rotation. The deformations occurring on the rail again impair the quality of the guidance of the slide part on the rail, as a result of which the deformation forces introduced into the rail become even greater. In any case, this can lead to the door drive working unnecessarily stiff and subject to wear.

Eine bekannte Profillaufschiene - AU-B-507794 - für Wandpaneele ist in ihrem unteren Teil als Hohlprofilabschnitt ausgebildet, in den eine Führungsausbildung eines Schlittenteils eingreift. Damit ist der Hohlprofilabschnitt der Profilschiene mit einem in deren Längsrichtung verlaufenden Schlitz versehen, der von Verbindungsbolzen zwischen der Führungsausbildung bzw. dem Schlittenteil und dem Paneel durchgriffen ist und der sich damit notwendig über die Verschiebestrecke des Schlittenteils hinweg erstreckt. Damit ist der Hohlprofilabschnitt gegen Durchbiegungen und vor allem auch gegen Verwindungen um seine Längsachse nicht optimal ausgebildet.A known profile track - AU-B-507794 - for wall panels is designed in its lower part as a hollow profile section, in which a guide formation of a slide part engages. The hollow profile section of the profile rail is thus provided with a slot running in the longitudinal direction thereof, which is penetrated by connecting bolts between the guide formation or the slide part and the panel and which therefore necessarily extends over the displacement distance of the slide part. The hollow profile section is thus not optimally designed against deflections and, above all, against twisting about its longitudinal axis.

Ein weiterhin bekannter Garagentorantrieb - US-A-3289350 - weist eine Fahrschiene auf, an der entlang ein an das Torblatt angelenkter Schlitten verfahrbar ist, der mittels eines an ihm angeordneten Antriebsmotors und Ritzels in eine sich längs der Fahrschiene erstreckende Zahnstange getrieblich eingreift. Die Fahrschiene weist ein bis auf Durchgriffsöffnungen im oberen Wandbereich geschlossen ausgebildetes Hohlprofil auf.A further known garage door drive - US-A-3289350 - has a travel rail along which a carriage articulated on the door leaf can be moved, which by means of a drive motor and pinion arranged on it engages in a gear rack extending along the travel rail. The running rail has a hollow profile which is closed except for access openings in the upper wall area.

Der Erfindung liegt die Aufgabe zugrunde, eine Profil-Laufschiene mit an dieser längsverschiebbar geführtem Schlittenteil der eingangs genannten Art zur Verfügung zu stellen, die unter Berücksichtigung der Forderung nach guter Handhabbarkeit, kleinem Gewicht und geringem Einbauplatzbedarf möglichst steif ist und vor allem eine entsprechend leichtgängige Längsverschiebeführung für das Schlittenteil sicherstellt.The invention has for its object to provide a profile rail with on this longitudinally guided slide part of the type mentioned, which is as stiff as possible, taking into account the requirement for good manageability, light weight and low space requirement, and above all a corresponding smooth-running longitudinal displacement guide ensures for the sled part.

Die Aufgabe wird erfindungsgemäss durch den Gegenstand des Anspruches 1 gelöst.The object is achieved according to the invention by the subject matter of claim 1.

Ein in sich geschlossenes Hohlprofil hat den Vorteil besonders hoher Widerstandsmomente gegen Biegung und vor allem gegen Verdrehung um die Profillängsachse. Erfindungsgemäss wird dieses gegen die auftretenden Belastungen demnach besonders formstabile Hohlprofil als Profilabschnitt im Bereich der Längsverschiebeführung für das Schlittenteil eingesetzt, wodurch die Führungsflächen der Laufschiene praktisch keiner durch Verbiegung oder Verdrehung hervorgerufenen Krümmung unterliegen. Es ergeben sich damit die Voraussetzungen für eine exakte Führung des Schlittenteils entlang der gesamten Längsverschiebestrecke der Schiene, und zwar bei spielarmer Auslegung des Eingriffs zwischen dem Schlittenteil und den Führungsflächen der Laufschiene, was im Hinblick auf die sonst auftretende Verkantungsgefahr zwischen Schlitten und Schiene von besonderer Bedeutung ist. Eine solche exakte Führung hat nicht nur den Vorteil einer verschleissarmen und energiesparenden Betriebsweise, sie ermöglicht auch eine feinfühligere Notabschaltung für den Fall, dass sich der Bewegung des Torblattes ein Hindernis in den Weg stellt und die Abschaltung des Antriebsmotors durch Überwachung des übertragenen Drehmomentes erfolgt.A self-contained hollow profile has the advantage of particularly high moments of resistance against bending and, above all, against rotation about the longitudinal axis of the profile. According to the invention, this is used to withstand the loads that are particularly dimensionally stable, as a profile section in the area of the longitudinal displacement guide for the slide part, so that the guide surfaces of the running rail are practically not subject to any curvature caused by bending or twisting. This results in the prerequisites for an exact guidance of the slide part along the entire longitudinal displacement distance of the rail, namely with a low-play design of the engagement between the slide part and the guide surfaces of the running rail, which is of particular importance in view of the otherwise risk of canting between the slide and rail is. Such precise guidance not only has the advantage of a low-wear and energy-saving mode of operation, it also enables a more sensitive emergency shutdown in the event that there is an obstacle to the movement of the door leaf and the drive motor is switched off by monitoring the transmitted torque.

In bevorzugter Ausführung werden an der Aussenwandung des Hohlprofilabschnittes in Profillängsrichtung verlaufende Führungsbahnen vorgesehen,die die Formstabilität des Hohlprofilabschnittes noch erhöhen und in welche Gleitstücke eingreifen, die im Bereich der Führungsausbildung an dem Schlittenteil vorgesehen sind. Die Gleitstücke können aus einem gegenüber dem Laufschienenwerkstoff besonders gleitfähigen Kunststoff bestehen und derart angeordnet sein, dass der Gleitangriff zwischen dem Schlittenteil und der Laufschiene ausschliesslich auf die Berührungsflächen zwischen den Gleitstücken und den Führungsbahnen beschränkt ist.In a preferred embodiment, guideways extending in the longitudinal direction of the profile are provided on the outer wall of the hollow profile section, which further increase the dimensional stability of the hollow profile section and which engage in sliders which are provided on the slide part in the area of the guide formation. The sliders can consist of a plastic that is particularly slidable with respect to the running rail material and can be arranged such that the sliding engagement between the slide part and the running rail is limited exclusively to the contact surfaces between the sliders and the guideways.

Weiterhin sind bevorzugt Führungsbahnen derart vorgesehen, dass sowohl quer zur Führungsrichtung verlaufende Bewegungen in horizontaler Ebene als auch in vertikaler Ebene aufgefangen werden. Zu diesem Zwecke kann im Bodenbereich des Hohlprofilabschnittes wenigstens eine und in dessen Seitenbereichen wenigstens eine weitere Führungsbahn vorgesehen sein.Furthermore, guideways are preferably provided in such a way that movements transverse to the guiding direction are absorbed in the horizontal plane as well as in the vertical plane. For this purpose, at least one guideway can be provided in the bottom region of the hollow profile section and at least one further guideway in the side regions thereof.

Eine besonders formsteife und fertigungstechnisch günstige Ausführung erhält man, wenn die Führungsbahnen durch an dem Hohlprofilabschnitt einstückig ausgeformte Vorsprünge gebildet werden. Durch die Anordnung der Führungsbahnen an der Aussenwandung des Hohlprofilabschnittes ergibt sich die Möglichkeit, die den Hohlraum quer zur Profillängsrichtung gesehen ringsumgebende Wandung ohne Spalt oder dergleichen geschlossen auszubilden, was der Formstabilität zugute kommt.A particularly dimensionally stable and technically favorable design is obtained if the guideways pass through the hollow profile cut integrally molded projections are formed. The arrangement of the guideways on the outer wall of the hollow profile section results in the possibility of forming the surrounding wall, as seen transversely to the longitudinal direction of the profile, without a gap or the like, which benefits the dimensional stability.

Insbesondere für den Fall, dass ein an dem Schlittenteil angreifendes Schleppglied, beispielsweise eine Kette, über die Länge der Laufschiene durchgehend oder abschnittweise geführt ist, wird in weiterer Ausgestaltung der Erfindung vorgeschlagen, den Hohlprofilabschnitt im unteren Profilflansch eines insgesamt I-förmigen Laufschienenprofils vorzusehen. Die dem unteren Flansch zugewandten Seiten des oberen Profilflansches können dann Befestigungsausbildungen aufweisen, die der Halterung des Schleppgliedes, beispielsweise über zwischengeschaltete Kettenführungsteile aus einem gegenüber dem Kettenwerkstoff gleitfähigen Kunststoff, dienen.In particular, in the event that a drag link, for example a chain, acting on the slide part is guided continuously or in sections over the length of the running rail, it is proposed in a further embodiment of the invention to provide the hollow profile section in the lower profile flange of an overall I-shaped running rail profile. The sides of the upper profile flange facing the lower flange can then have fastening designs which serve to hold the drag link, for example via interposed chain guide parts made of a plastic that is slidable relative to the chain material.

Weitere Ausgestaltungen der Erfindung ergeben sich aus Unteransprüchen im Zusammenhang mit dem in der Zeichnung wiedergegebenen Ausführungsbeispiel, auf das besonders Bezug genommen wird und dessen nachstehende Beschreibung die Erfindung näher erläutert.Further refinements of the invention result from subclaims in connection with the exemplary embodiment shown in the drawing, to which particular reference is made and the description below of which explains the invention in more detail.

Die Zeichnung zeigt einen Querschnitt durch das Laufschienenprofil und eine Seitenansicht des in Führungsposition befindlichen Schlittenteils des Ausführungsbeispieles.The drawing shows a cross section through the track profile and a side view of the slide part of the exemplary embodiment located in the guide position.

Die insgesamt mit 1 bezeichnete Profillaufschiene besitzt ein I-förmiges Profil, dergestalt, dass an einem in der Gebrauchslage vertikal verlaufenden Steg 2 ein etwa in gleicher Wandstärke gehaltener oberer Profilflansch 3 und ein insgesamt mit 4 bezeichneter unterer Profilflansch angeformt sind. Der untere Profilflansch umfasst einen Hohlprofilabschnitt 5 mit einem Hohlraum 6, der quer zur Profillängsrichtung gesehen von einer in sich geschlossenen Wandung umgeben ist. Ein solches geschlossenes Hohlprofil besitzt ein besonders hohes polares Widerstandsmoment.The overall profile rail designated 1 has an I-shaped profile, such that an upper profile flange 3 held approximately in the same wall thickness and an overall lower profile flange 4 are formed on a web 2 that runs vertically in the position of use. The lower profile flange comprises a hollow profile section 5 with a cavity 6 which, seen transversely to the longitudinal direction of the profile, is surrounded by a self-contained wall. Such a closed hollow profile has a particularly high polar section modulus.

An der Aussenwandung 7 des Hohlprofilabschnittes 5 sind seitlich und nach unten abstehende Vorsprünge ausgeformt, die in Längsrichtung der Profilschiene verlaufende Führungsbahnen begrenzen. So sind - von der Seite des oberen Profilflansches 3 her gesehen - zunächst an der Aussenwandung 7 des Hohlprofilabschnittes 5 Vorsprünge 8 vorgesehen, von denen einer an der linken Seite und einer an der rechten Seite des Profilabschnittes seitlich vorspringend ausgeformt sind. Im Bodenbereich an der der Anformungsstelle des Steges 2 gegenüberliegenden Stelle ist ein nach unten abragender Vorsprung 9 ausgebildet. In den Übergangsbereichen zwischen dem Bodenbereich und den Seitenbereichen ist jeweils ein winkelförmiger Vorsprung ausgeformt, die jeweils aus einem nach unten abragenden Fussteil 11 und einem sich rechtwinklig daran anschliessenden, seitlich abragenden Endteil 12 bestehen. Die Anordnung ist dabei so getroffen, dass auf jeder Seite zwischen dem Vorsprung 8 und dem Endteil 12 des zugehörigen winkelförmigen Vorsprunges 10 eine U-förmige, zur Seite hin offene Führungsbahn 13 gebildet wird, während im Bodenbereich zwischen dem mittleren Vorsprung 9 und den Fussteilen 11 und 12 der beiden winkelförmigen Vorsprünge 10 zwei nach unten geöffnete, U-förmige Führungsbahnen 14 definiert sind.On the outer wall 7 of the hollow profile section 5, protrusions protruding laterally and downward are formed, which limit guideways running in the longitudinal direction of the profile rail. Thus - as seen from the side of the upper profile flange 3 - 5 projections 8 are initially provided on the outer wall 7 of the hollow profile section, one of which is laterally projecting on the left side and one on the right side of the profile section. A downwardly projecting projection 9 is formed in the bottom area at the point opposite the molding point of the web 2. An angular projection is formed in each of the transition areas between the bottom area and the side areas, each of which consists of a foot part 11 projecting downwards and a laterally projecting end part 12 adjoining it at right angles. The arrangement is such that a U-shaped, open to the side guideway 13 is formed on each side between the projection 8 and the end part 12 of the associated angular projection 10, while in the bottom region between the middle projection 9 and the foot parts 11 and 12 of the two angular projections 10, two downwardly open, U-shaped guideways 14 are defined.

An den dem unteren Profilflansch 4 zugewandten Innenseiten des oberen Profilflansches 3 sind beidseits des Steges 2 Befestigungsausbildungen 15 ausgeformt, die einen T-förmigen Querschnitt aufweisen und sich in Längsrichtung der Profil- laufschiene erstrecken. Unterhalb dieser Befestigungsausbildungen 15 verlaufen die beiden Trume einer als Schleppglied dienenden Gliederkette 16, die in nicht dargestellter Weise in endloser Ausführung um zwei Ritzel umgelenkt verläuft, deren eines an dem einen Ende der Profil- laufschiene angeordnet und als Antriebsritzel mit dem nicht dargestellten Antriebsmotoraggregat getrieblich verbunden ist, während sich das andere Ritzel am anderen Ende der Profillaufschiene verbindet und freidrehend gelagert als Umkehrritzel für die Kette 16 dient. Um ein Durchhängen der Kette im Bereich der Trume zu verhindern, sind an den Befestigungsausbildungen 15 der Profillaufschiene 1 Kettenführungsteile 17 gehalten, die nicht näher dargestellte Hohlräume aufweisen, in denen die nach oben gewandten Scharnierglieder der Kette längsbeweglich gelagert sind. Die Kettenführungsteile 17 bestehen aus einem Kunststoff, der gute Gleiteigenschaften in Bezug auf das Material der Kette 16 aufweist. Die Kettenführungsteile 17 können über die Trumlänge der Kette hinweggeführt ausgebildet sein, sie können aber auch nur auf kurze Kettenlängenabschnitte beschränkt und in grösseren Abschnitten aufeinanderfolgend in mehreren Teilen vorgesehen sein, zwischen denen die Abschnitte des jeweilig betrachteten Kettentrums freihängend gehalten sind. Die Kettenführungsteile 17 können auf verschiedene Weise an den Befestigungsausbildungen 15 befestigt werden, beispielsweise dadurch, dass sie in einer vertikalen, sich in Profillängsrichtung erstreckenden Ebene geteilt und durch entsprechende Verbindungsschrauben gegen die Ausbildungen 15 verpresst zusammengeschraubt sind.On the inner side of the upper profile flange 3 facing the lower profile flange 4, fastening designs 15 are formed on both sides of the web, which have a T-shaped cross section and extend in the longitudinal direction of the profile running rail. Below these fastening designs 15 run the two strands of a link chain 16 serving as a drag link, which, in a manner not shown, runs in an endless manner around two sprockets, one of which is arranged at one end of the profile running rail and connected as a drive pinion to the drive motor unit (not shown) is while the other sprocket connects to the other end of the profile rail and is freely rotating and serves as a reversing sprocket for the chain 16. In order to prevent sagging of the chain in the region of the strands, 1 chain guide parts 17 are held on the fastening formations 15 of the profile running rail, which have cavities, not shown, in which the upwardly facing hinge links of the chain are mounted so as to be longitudinally movable. The chain guide parts 17 consist of a plastic which has good sliding properties with respect to the material of the chain 16. The chain guide parts 17 can be formed over the strand length of the chain, but they can also be limited to short chain length sections and can be provided in larger sections in succession in several parts, between which the sections of the chain center in question are held freely suspended. The chain guide parts 17 can be fastened to the fastening formations 15 in various ways, for example by dividing them in a vertical plane extending in the longitudinal direction of the profile and screwing them together by means of corresponding connecting screws pressed against the formations 15.

Der gesamte untere Profilflansch 4 durchgreift eine Führungsausbildung 18, die in Form eines Hohlraumes innerhalb des Schlittenteiles 19 ausgebildet ist, welches den unteren Profilflansch 4 in Form des Hohlprofilabschnittes 5 mit den an seiner Aussenwandung 7 vorgesehenen Führungsbahnen 13 und 14 bis auf einen Schlitzbereich, der vom Steg 2 der Profillaufschiene 1 durchgriffen wird, umfasst. An denjenigen Innenseiten der Führungsausbildung 18, die den seitlichen Führungskanälen 13 und den bodenseitigen Führungskanälen 14 gegenüberliegen, sind Gleitstücke 20 befestigt, die in die jeweils zugehörigen Führungsbahnen eingreifen. Die Befestigung der Gleitstücke 20 an dem Schlittenteil 19 ist mit Hilfe von Schrauben 21 bewerkstelligt. Die Gleitstücke sind aus einem Kunststoff gefertigt, der gegenüber der Aluminiumlegierung, aus der die Profillaufschiene insgesamt hergestellt ist, gute Gleiteigenschaften aufweist.The entire lower profile flange 4 passes through a guide formation 18, which is designed in the form of a cavity within the slide part 19, which forms the lower profile flange 4 in the form of the hollow profile section 5 with the guide tracks 13 and 14 provided on its outer wall 7, except for a slot area which extends from the Web 2 of the profile rail 1 is reached, includes. On those inner sides of the guide formation 18, which lie opposite the lateral guide channels 13 and the bottom-side guide channels 14, sliders 20 are fastened which engage in the respectively associated guide tracks. The fastening of the sliders 20 on the slide part 19 is accomplished with the aid of screws 21. The Sliders are made of a plastic that has good sliding properties compared to the aluminum alloy from which the profile rail is made.

Das Schlittenteil 19 hat eine bestimmte Ausdehnung in Längsrichtung der Profillaufschiene 1, über welche sich die Gleitstücke 20 pro Führungsbahn 13 bzw. 14 hinweg erstrecken oder in Form mehrerer entsprechend hintereinander angeordneter Einzelstücke gleichmässig beabstandet hintereinander angeordnet sind. In jedem Falle wird dadurch sichergestellt, dass die im Bodenbereich in die Führungsbahnen 14 eingreifenden Gleitstücke 20 eine Verkantung des Schlittenteils 19 quer zur Längsrichtung der Profillaufschiene 1 in horizontaler Ebene verhindern. In ähnlicher Weise wird durch den Eingriff der entsprechenden Gleitstücke 20 in die seitlichen Führungsbahnen 13 vermieden, dass das Schlittenteil in vertikaler, etwa senkrecht zur Längsrichtung der Profillaufschiene 1 gelegenen Ebene verschwenkt werden kann. Auf diese Weise wird eine exakte Führung des Schlittenteils an dem unteren Profilflansch 4 sichergestellt, wobei das Spiel zwischen den Gleitstücken 20 und den anliegenden Flächen, insbesondere Schenkelinnenflächen, der Führungsbahnen sehr gering gehalten werden kann. Die besondere Formstabilität des Hohlprofilabschnittes zusammen mit dem an ihm ausgeformter Vorsprüngen ermöglicht den unbeeinträchtigten Verschiebevorgang des Schlittenteils 19 an dem unteren Profilflansch 4, wodurch über die gesamte Verschiebestrecke hinweg ein gleichmässiger Verschiebewiderstand zwischen dem Schlittenteil und der Laufschiene erreicht wird.The slide part 19 has a certain extent in the longitudinal direction of the profile rail 1, over which the sliding pieces 20 extend per guideway 13 or 14 or are arranged in the form of a plurality of individual pieces arranged one behind the other and evenly spaced behind one another. In any case, this ensures that the sliders 20 engaging in the guide tracks 14 in the floor area prevent the slide part 19 from tilting transversely to the longitudinal direction of the profile running rail 1 in the horizontal plane. Similarly, the engagement of the corresponding slide pieces 20 in the lateral guideways 13 prevents the slide part from being able to be pivoted in a vertical plane, approximately perpendicular to the longitudinal direction of the profile running rail 1. In this way, an exact guidance of the slide part on the lower profile flange 4 is ensured, the play between the slides 20 and the adjacent surfaces, in particular inner leg surfaces, of the guideways being kept very low. The special dimensional stability of the hollow profile section together with the projections formed on it enables the unimpeded displacement process of the slide part 19 on the lower profile flange 4, as a result of which a uniform displacement resistance is achieved between the slide part and the running rail over the entire displacement distance.

Im äusseren Bodenbereich des Schlittenteils 19 ist eine Gelenkhebel-Verbindung 22 angedeutet, über welche das Schlittenteil 19 mit einem nicht dargestellten, zu öffnenden und zu schliessenden Torblatt verbunden ist. In einem Seitenbereich des Schlittenteils 19 ist ein insgesamt mit 23 bezeichnetes Kupplungsstück gehalten, das in ein Mitnehmerstück 24 eingreift, welches seinerseits mit der Kette 16 fest verbunden ist. Das Mitnehmerteil 24 wird demnach von der über den Antriebsmotor bewegten Kette 16 mitgenommen, im Einkupplungszustand überträgt sich diese Bewegung über das Kupplungsstück 23 auf das Schlittenteil 19, das die entsprechende Längsverschiebebewegung auf das Torblatt überträgt.In the outer bottom area of the slide part 19, an articulated lever connection 22 is indicated, via which the slide part 19 is connected to a door leaf (not shown) that can be opened and closed. In one side area of the slide part 19, a coupling piece, designated overall by 23, is held, which engages in a driver piece 24, which in turn is firmly connected to the chain 16. The driver part 24 is accordingly entrained by the chain 16 moved via the drive motor, in the coupling state this movement is transmitted via the coupling piece 23 to the slide part 19, which transmits the corresponding longitudinal displacement movement to the door leaf.
