Description

Die Erfindung betrifft eine Antriebsvorrichtung für ein entlang einer Führung geführtes Torblatt oder dergleichen mit einem an einem Bauwerk befestigten Antriebskopf, der einen Antriebsmotor aufweist, einem Antriebsritzel, einem Umlenkritzel und einer über Antriebsritzel und Umlenkritzel gelegten und umlaufenden Kette oder dergleichen mit einem am Torblatt oder dergleichen befestigten Mitnahmeelement.The invention relates to a drive device for a door leaf or the like guided along a guide with a drive head fastened to a structure, which has a drive motor, a drive pinion, a deflection pinion and a chain or the like placed and driven over the drive pinion and deflection pinion and the like with a on the door leaf or the like attached driving element.

Derartige Antriebsvorrichtungen sind aus dem Stand der Technik bekannt. Sie haben in der Regel einen Antriebskopf, der einen Antriebsmotor aufweist, auf dessen Antriebswelle ein Getriebe und daran anschließend ein Antriebsritzel angeordnet ist. Die vorbekannten Antriebsvorrichtungen weisen darüberhinaus ein Umlenkritzel auf, über das eine Kette endlos geführt ist, die über das Umlenkritzel und über das Antriebsritzel läuft und derart angeordnet ist, daß die rotatorische Bewegung des Antriebsmotors in eine translatorische Bewegung des an der Kette befestigten Mitnahmeelements umgesetzt wird. Dieses Mitnahmeelement ist an dem Torblatt oder dergleichen befestigt, so daß durch die Umsetzung der rotatorischen Bewegung des Antriebsmotors in die translatorische Bewegung des Mitnahmeelementes eine Bewegung des Torblattes oder dergleichen entlang einer Führung ausgeführt wird. Die zuvor beschriebene Antriebsvorrichtung kann insbesondere für den Antrieb eines hin- und her bewegbaren Gegenstandes entlang einer Führungsschiene mit einem Schlitten vorgesehen sein, der entlang der Führungsschiene bewegbar geführt und von dem Kettentrum bewegt ist. Mit solchen Antriebsvorrichtungen können beispielsweise ein- oder mehrteilige Torblätter von Industrie- oder Garagentoren zwischen der Öffnungslage und der Schließlage hin- und herbewegt werden.Such drive devices are known from the prior art. They usually have a drive head which has a drive motor, on the drive shaft of which a gear and then a drive pinion is arranged. The known drive devices also have a deflection sprocket, over which a chain is guided endlessly, which runs over the deflection sprocket and over the drive sprocket and is arranged such that the rotational movement of the drive motor is converted into a translatory movement of the driving element fastened to the chain. This driving element is attached to the door leaf or the like, so that a movement of the door leaf or the like is carried out along a guide by the conversion of the rotary movement of the drive motor into the translational movement of the driving element. The drive device described above can be used, in particular, to drive an object that can be moved back and forth along a guide rail with a slide be provided, which is movably guided along the guide rail and moved by the chain center. With such drive devices, for example, single or multi-part door leaves of industrial or garage doors can be moved back and forth between the open position and the closed position.

Hierbei ist es erforderlich, daß der Abstand zwischen dem mit dem Antriebsmotor verbundenen Antriebsritzel und dem Umlenkritzel derart groß bemessen ist, daß beispielsweise das Torblatt in die gewünschten Endstellungen bewegbar ist. Es hat sich im Stand der Technik gezeigt, daß bei der Montage des Antriebskopfes und des Umlenkritzels sowie der darauffolgenden Montage der Kette Probleme in soweit auftauchen, daß die Montage der Bauteile durch die Vielzahl der Montageschritte aufwendig ist und daß erhöhte Spannungen durch eine ungenaue Ausrichtung von Antriebskopf und Umlenkritzel auftreten können, die dazu führen, daß das zu bewegende Torblatt nicht im gewünschten Maße leichtgängig ist. Hierbei sind insbesondere dadurch Probleme aufgetreten, daß die Montage von Antriebskopf und Umlenkzahnrad aufgrund der auftretenden Kräfte mit stabilen Befestigungselementen erfolgen muß, beispielsweise mit entsprechend dimensionierten Bolzen, die in eine Wand des Bauwerks geschraubt werden. Das Auflegen der Kette und die Einstellung der Kettenvorspannung fällt dagegen eher in den Bereich der Feinmechanik und ist nur dann in einfacher Weise durchführbar, wenn die zuvor montierten Bauteile, nämlich der Antriebskopf und das Umlenkritzel lagegenau angeordnet sind, so daß ein einwandfreier Lauf der Kette um diese Antriebselemente erfolgen kann.It is necessary that the distance between the drive pinion connected to the drive motor and the deflection pinion is dimensioned so large that, for example, the door leaf can be moved into the desired end positions. It has been shown in the prior art that problems arise in the assembly of the drive head and the deflection pinion and the subsequent assembly of the chain to the extent that the assembly of the components is complex due to the large number of assembly steps and that increased voltages due to an inaccurate alignment of Drive head and deflection pinion can occur, which lead to the fact that the door leaf to be moved is not smoothly to the desired extent. Problems have arisen here in particular that the assembly of the drive head and the deflection gear has to be carried out with stable fastening elements, for example with appropriately dimensioned bolts which are screwed into a wall of the building due to the forces which occur. Placing the chain and adjusting the chain pretension, on the other hand, falls more in the field of precision engineering and can only be carried out in a simple manner if the previously assembled components, namely the drive head and the deflection pinion, are arranged in the correct position, so that the chain runs smoothly these drive elements can be done.

Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine Antriebsvorrichtung der eingangs beschriebenen Art zu schaffen, die in einfacher Weise montierbar ist und die keine umfangreichen feinmechanische Einstellarbeiten während und nach der Montage erfordert.Based on this prior art, the invention has for its object to provide a drive device of the type described above, which is easy to assemble and which does not require extensive fine mechanical adjustment work during and after assembly.

Die Lösung dieser Aufgabenstellung sieht bei einer erfindungsgemäßen Antriebsvorrichtung vor, daß das Antriebsritzel, das Umlenkritzel und die umlaufende Kette in einer Führungsschiene angeordnet sind eine komplett vormontierte Einheit bilden und daß die vormontierte Einheit getrieblich mit dem Antriebskopf verbindbar ist.The solution to this problem provides in a drive device according to the invention that the drive pinion, the deflection pinion and the rotating chain are arranged in a guide rail, a completely pre-assembled Form unit and that the preassembled unit is geared to the drive head.

Demzufolge sieht die erfindungsgemäße Antriebsvorrichtung eine komplett vormontierte Einheit vor, die aus einer Führungsschiene besteht, an der sowohl das Antriebsritzel als auch das Umlenkritzel befestigt sind und in der ferner die Kette umläuft. Diese komplett vormontierte Einheit bildet zusammen mit dem Antriebskopf die komplette Antriebsvorrichtung, wobei die komplett vormontierte Einheit getrieblich mit dem Antriebskopf verbindbar ist. Demnach besteht die Antriebsvorrichtung aus nur zwei Bauteilen, die in einfacher Weise an dem Bauwerk montierbar sind und die insbesondere nach der Montage keine umfangreichen feinmechanischen Einstellarbeiten erfordern. Es ist bei einer erfindungsgemäßen Antriebsvorrichtung notwendig, in einem ersten Montageschritt den Antriebskopf mit dem Antriebsmotor am Bauwerk zu befestigen, woraufhin nachfolgend die komplett vormontierte Einheit, bestehend aus Antriebsritzel, Umlenkritzel, Kette und Führungsschiene am Bauwerk als auch am Antriebskopf derart befestigt wird, daß Antriebskopf und vormontierte Einheit getrieblich miteinander verbunden sind. Abschließend muß dann nur noch das Mitnahmeelement, welches an der Kette vormontiert ist, mit dem Torblatt verbunden werden.Accordingly, the drive device according to the invention provides a completely preassembled unit which consists of a guide rail to which both the drive pinion and the deflection pinion are fastened and in which the chain also rotates. This completely preassembled unit forms the complete drive device together with the drive head, the completely preassembled unit being operatively connectable to the drive head. Accordingly, the drive device consists of only two components that can be easily installed on the structure and that do not require extensive fine-mechanical adjustment work, particularly after installation. It is necessary in a drive device according to the invention to fasten the drive head with the drive motor to the structure in a first assembly step, whereupon the completely preassembled unit consisting of drive pinion, deflection pinion, chain and guide rail is fastened to the structure and to the drive head in such a way that the drive head and the preassembled unit are connected to each other by gears. Finally, only the driving element, which is pre-assembled on the chain, has to be connected to the door leaf.

Nach einer vorteilhaften Weiterbildung der erfindungsgemäßen Antriebsvorrichtung ist vorgesehen, daß der Antriebsmotor auf seiner Antriebswelle ein Zahnrad aufweist, das mit einem Zahnrad kämmt, welches das Drehmoment des Antriebsmotors auf das Antriebsritzel überträgt. Bei dieser Ausgestaltung wird eine besonders einfache getriebliche Verbindung zwischen Antriebskopf und der vormontierten Einheit erzielt, die eine einfache Verbindung zwischen diesen Bauteilen bei der Montage der Antriebsvorrichtung in einem Bauwerk ermöglicht. Es hat sich hierbei als vorteilhaft erwiesen, das Antriebsritzel und das Zahnrad koaxial und verdrehfest auf einer Welle anzuordnen, die drehbar in der Führungsschiene angeordnet ist. Bei dieser Ausgestaltung wird das vom Antriebsmotor abgegebene Drehmoment nun im wesentlichen unmittelbar auf das Antriebsritzel übertragen.According to an advantageous development of the drive device according to the invention it is provided that the drive motor has on its drive shaft a gear which meshes with a gear which transmits the torque of the drive motor to the drive pinion. In this embodiment, a particularly simple gear connection between the drive head and the preassembled unit is achieved, which enables a simple connection between these components when the drive device is installed in a building. It has proven to be advantageous here to arrange the drive pinion and the gearwheel coaxially and non-rotatably on a shaft which is rotatably arranged in the guide rail. In this embodiment, the torque output by the drive motor is now essentially transmitted directly to the drive pinion.

Eine weitere Vereinfachung der Montage der erfindungsgemäßen Antriebsvorrichtung am Bauwerk wird dadurch erzielt, daß der Antriebskopf eine Führung hat, in die die vormontierte Einheit derart einschiebbar ist, daß die vormontierte Einheit getrieblich mit dem Antriebskopf verbunden ist. Eine derart ausgebildete Antriebsvorrichtung hat demzufolge einen Antriebskopf, der beispielsweise eine U-förmig ausgebildete Führung aufweist, in die die vormontierte Einheit einschiebbar ist, bis zu einem Punkt, an dem die getriebliche Verbindung zwischen dem Antriebskopf und der vormontierten Einheit besteht.A further simplification of the assembly of the drive device according to the invention on the structure is achieved in that the drive head has a guide into which the preassembled unit can be inserted in such a way that the preassembled unit is connected to the drive head in a geared manner. A drive device designed in this way consequently has a drive head which, for example, has a U-shaped guide into which the preassembled unit can be inserted, up to a point at which there is a gear connection between the drive head and the preassembled unit.

Es ist bei einer Weiterbildung der erfindungsgemäßen Antriebsvorrichtung vorgesehen, daß die Führungsschiene der vormontierten Einheit als im wesentlichen U-förmiges Profil ausgebildet ist, welches zwei Schenke und einen die Schenke verbindenden Steg aufweist und daß das Antriebsritzel und das Umlenkritzel jeweils auf einer Welle gelagert sind, die mit dem Steg verbunden ist. Die Ausbildung der Führungsschiene als im wesentlichen U-förmig ausgebildetes Profil hat insbesondere den Vorteil, daß eine derartige Führungsschiene eine große Festigkeit aufweist. Ferner bietet eine im wesentlichen U-förmig ausgebildete Führungsschiene mit zwei Schenkeln und einem die Schenkel verbindenden Steg den Vorteil, daß die zwischen den Schenkeln umlaufende Kette abgedeckt ist, so daß einerseits die Kette und die weiteren zwischen den Schenkeln angeordneten Antriebselemente vor Beschädigungen geschützt sind. Andererseits wird durch diese Ausgestaltungen das Verletzungsrisiko von Personen verringert, welches dadurch besteht, daß diese Personen bei Unachtsamkeit mit ihren Fingern oder ihren Haaren zwischen Kette und Ritzel geraten können. Hierbei hat es sich als vorteilhaft erwiesen, an den im wesentlichen U-förmig ausgebildeten Führungsschienen zwei weitere Stege anzuordnen, die an den freien Enden der Schenkel befestigt sind und aufeinander zu verlaufen. Diese Schenkel decken die umlaufende Kette ab, so daß hierdurch die voranstehenden Beeinträchtigungen des Betriebes der erfindungsgemäßen Antriebsvorrichtung weiter eingeschränkt werden.In a development of the drive device according to the invention, it is provided that the guide rail of the preassembled unit is designed as an essentially U-shaped profile, which has two legs and a web connecting the legs, and that the drive pinion and the deflection pinion are each mounted on a shaft, which is connected to the web. The design of the guide rail as a substantially U-shaped profile has the particular advantage that such a guide rail has great strength. Furthermore, a substantially U-shaped guide rail with two legs and a web connecting the legs has the advantage that the chain running between the legs is covered, so that on the one hand the chain and the further drive elements arranged between the legs are protected from damage. On the other hand, these designs reduce the risk of injury to people, which consists of the fact that these people can get into the chain and sprocket with their fingers or their hair if they are careless. Here, it has proven to be advantageous to arrange two further webs on the essentially U-shaped guide rails, which are fastened to the free ends of the legs and run towards one another. These legs cover the revolving chain, so that the above impairments of the operation of the drive device according to the invention are further restricted.

Bei einem ersten Ausführungsbeispiel der erfindungsgemäßen Antriebsvorrichtung ist vorgesehen, daß das Antriebsritzel zwischen dem Steg und dem Zahnrad angeordnet ist. Diese Ausbildung bietet insbesondere den Vorteil, daß beispielsweise das Zahnrad in einfacher Weise ausgewechselt werden kann, um eine Drehzahl- bzw. eine Geschwindigkeitsanpassung vornehmen zu können. Beispielsweise kann das antriebsritzelseitige Zahnrad dann ausgewechselt werden, wenn eine an das Torblatt angepaßte Torlaufgeschwindigkeit erzielt werden soll; beispielsweise wenn große Tore sehr langsam laufen sollen.In a first embodiment of the drive device according to the invention it is provided that the drive pinion is arranged between the web and the gear. This design has the particular advantage that, for example, the gear wheel can be replaced in a simple manner in order to be able to adjust the speed or speed. For example, the pinion gear on the drive pinion can be replaced when a door running speed adapted to the door leaf is to be achieved; for example when large gates are supposed to run very slowly.

Bei einer zweiten Ausführungsform der Erfindung ist vorgesehen, daß das Zahnrad zwischen dem Steg und dem Antriebsritzel angeordnet ist.In a second embodiment of the invention it is provided that the gear wheel is arranged between the web and the drive pinion.

Schließlich ist bei der erfindungsgemäßen Antriebsvorrichtung vorgesehen, daß das in der Führungsschiene angeordnete Zahnrad derart in Längsrichtung über die Führungsschiene hinausragt, daß beim Einschieben der Führungsschiene in radialer Richtung des Zahnrades in die Führung des Antriebskopfes das Zahnrad in Eingriff mit dem auf der Antriebswelle des Antriebsmotors angeordnete Zahnrad gelangt.Finally, it is provided in the drive device according to the invention that the gear arranged in the guide rail projects in the longitudinal direction beyond the guide rail in such a way that when the guide rail is inserted in the radial direction of the gear into the guide of the drive head, the gear engages with that arranged on the drive shaft of the drive motor Gear comes.

a second embodiment of a pre-assembled unit in a sectional side view. One in the figure 1 shown drive device 1 is used to drive a door leaf, for example a garage, which is guided in two guides and can be moved back and forth between an open position and a closed position. The drive device 1 has a drive head 2, which consists of a housing 3, in which a drive motor, not shown, and a transmission, not shown, are arranged.

Eine Abtriebswelle 4 ist drehfest mit einem Zahnrad verbunden, welches in einer Führung 6 des Gehäuses 3 angeordnet ist. Das Zahnrad 5 ist derart in der Führung 6 angeordnet, daß seine Radialrichtung parallel zur Längsrichtung der Führung 6 verläuft.An output shaft 4 is connected in a rotationally fixed manner to a gearwheel which is arranged in a guide 6 of the housing 3. The gear wheel 5 is arranged in the guide 6 such that its radial direction runs parallel to the longitudinal direction of the guide 6.

In der Führung 6 ist eine Vielzahl von Bohrungen 7 angeordnet, durch welche nicht dargestellte Bolzen oder Schrauben steckbar sind, die der Befestigung des Antriebskopfes 2 an einer nicht dargestellten Wand eines Bauwerks dienen.A plurality of bores 7 are arranged in the guide 6, through which bolts or screws (not shown) can be inserted, which are used to fasten the drive head 2 to a wall of a building, not shown.

Die Antriebsvorrichtung 1 weist ferner eine vormontierte Einheit 8 auf, die nachfolgend anhand der Figuren 2 bis 4 detailliert beschrieben wird.The drive device 1 also has a preassembled unit 8, which is described in detail below with reference to FIGS. 2 to 4.

Die vormontierte Einheit 8 besteht aus einer Führungsschiene 9, die als U-förmiges Profil ausgebildet ist und demnach zwei Schenkel 10, 11 und einen die beiden Schenkel 10, 11 verbindenden Steg 12 hat. An den freien Enden der Schenkel 10, 11 ist jeweils ein Steg 13 derart befestigt, daß beide Stege 13 parallel zum Steg 12 und aufeinanderzu verlaufen.The preassembled unit 8 consists of a guide rail 9 which is designed as a U-shaped profile and accordingly has two legs 10, 11 and a web 12 connecting the two legs 10, 11. At the free ends of the legs 10, 11 a web 13 is fastened in such a way that both webs 13 run parallel to the web 12 and toward one another.

Die Führungsschiene 9 hat an ihren gegenüberliegenden Enden jeweils eine Welle 14 bzw. 15. Auf der Welle 14 sind ein Zahnrad 16 und ein Antriebsritzel 17 koaxial und verdrehfest angeordnet. Antriebsritzel 17 und Zahnrad 16 sind drehbar in der Führungsschiene 9 gehaltert, wobei zumindest das Zahnrad 16 über die Schmalseite 18 der Führungsschiene 9 hervorragt.The guide rail 9 has at its opposite ends a shaft 14 and 15, respectively. A gear 16 and a drive pinion 17 are arranged coaxially and non-rotatably on the shaft 14. Drive pinion 17 and gear 16 are rotatably supported in the guide rail 9, with at least the gear 16 protruding beyond the narrow side 18 of the guide rail 9.

Auf der Welle 14 ist ein Umlenkritzel 19 befestigt, welches über eine Kette 20 getrieblich mit dem Antriebsritzel 17 verbunden ist. Die Kette 20 ist als endlose Rollenkette ausgebildet und läuft über das Antriebsritzel 17 und das Umlenkritzel 19 in der Führungsschiene 9 um. An der Kette 20 ist ein in der Zeichnung nicht dargestelltes Mitnahmeelement befestigt, welches die Kette 20 mit dem Torblatt verbindet.A deflection pinion 19 is fastened on the shaft 14 and is connected to the drive pinion 17 via a chain 20. The chain 20 is designed as an endless roller chain and rotates in the guide rail 9 via the drive pinion 17 and the deflection pinion 19. On the chain 20, a driving element, not shown in the drawing, is fastened, which connects the chain 20 to the door leaf.

Wie insbesondere aus der Figur 2 zu erkennen ist, ist das Umlenkritzel 19 derart in der Führungsschiene 9 drehbar gehaltert, daß kein Teil des Umlenkritzels 19 über die Seiten der Führungsschiene 9 hervorsteht. Die Stege 13 sind derart angeordnet und bemessen, daß sie die umlaufende Kette 20, insbesondere im Bereich des Auf- und Ablaufens auf das Antriebsritzel 17 und das Umlenkritzel 19 abdecken.As can be seen in particular from FIG. 2, the deflection pinion 19 is rotatably supported in the guide rail 9 in such a way that no part of the deflection pinion 19 protrudes beyond the sides of the guide rail 9. The webs 13 are arranged and dimensioned such that they cover the revolving chain 20, in particular in the region of the run-up and run-down on the drive pinion 17 and the deflection pinion 19.

In den Figuren 3 und 4 sind zwei Ausführungsbeispiele verschiedener vormontierter Einheiten 8 dargestellt. Bei dem Ausführungsbeispiel gemäß Figur 3 ist das Antriebsritzel 17 zwischen dem Steg 12 der Führungsschiene 9 und dem Zahnrad 16 angeordnet. Bei dieser Ausgestaltung ist es besonders einfach möglich, das Zahnrad von der Welle 14 zu lösen, um beispielsweise ein an die Antriebsbedingungen angepaßtes größeres oder kleineres Zahnrad 16 auf der Welle 14 zu montieren.FIGS. 3 and 4 show two exemplary embodiments of different preassembled units 8. In the embodiment shown in Figure 3, the drive pinion 17 is arranged between the web 12 of the guide rail 9 and the gear 16. With this configuration, it is particularly easy to detach the gearwheel from the shaft 14, for example in order to mount a larger or smaller gearwheel 16 adapted to the drive conditions on the shaft 14.

Bei dem in Figur 4 dargestellten Ausführungsbeispiel ist das Zahnrad 16 zwischen dem Antriebsritzel 17 und dem Steg 12 der Führungsschiene 9 angeordnet.In the embodiment shown in Figure 4, the gear 16 is arranged between the drive pinion 17 and the web 12 of the guide rail 9.

In der Figur 1 ist die Montage der vormontierten Einheit 8 in dem Antriebskopf 2 schematisch dargestellt. Bei der Montage der erfindungsgemäßen Antriebsvorrichtung 1 wird in einem ersten Schritt der Antriebskopf 2 an einer Wand des Bauwerks befestigt, wobei vorzugsweise eine Verschraubung des Antriebskopfes 2 mit der Wand vorgesehen ist. Anschließend wird die vormontierte Einheit 8 mit dem das Zahnrad 16 aufweisenden Ende in die Führung 6 des Antriebskopfes 2 eingeschoben, bis das Zahnrad 16 der vormontierten Einheit 8 mit dem Zahnrad 5 des Antriebskopfes 2 kämmt und somit eine getriebliche Verbindung zwischen der vormontierten Einheit 8 und dem Antriebskopf 2 hergestellt ist. Abschließend wird die Führungsschiene 9 ebenfalls mit an der Wand des Bauwerks befestigt und das nicht dargestellte Mitnahmeelement der Kette 20 mit dem Torblatt verbunden. In der Figur 1 ist die Einschubrichtung der komplett vormontierten Einheit 8 durch einen Pfeil 21 dargestellt.In Figure 1, the assembly of the pre-assembled unit 8 in the drive head 2 is shown schematically. When assembling the drive device 1 according to the invention, the drive head 2 is fastened to a wall of the building in a first step, preferably screwing the drive head 2 to the wall. The preassembled unit 8 is then inserted into the guide 6 with the end having the gear 16 of the drive head 2 inserted until the gear 16 of the pre-assembled unit 8 meshes with the gear 5 of the drive head 2 and thus a gear connection between the pre-assembled unit 8 and the drive head 2 is made. Finally, the guide rail 9 is also fastened to the wall of the building and the driving element, not shown, of the chain 20 is connected to the door leaf. In Figure 1, the direction of insertion of the completely pre-assembled unit 8 is shown by an arrow 21.

Die erfindungsgemäße Antriebsvorrichtung stellt somit eine weitgehend vormontierte Ausführung dar, die eine getriebliche Verbindung zwischen dem Antriebsmotor und dem Torblatt oder dergleichen in einfacher Weise zur Verfügung stellt. Der Grundgedanke ist insbesondere darin zu sehen, daß eine die rotatorische Antriebsbewegung des Antriebsmotors in eine translatorische Abtriebsbewegung eines Gebäudeverschlusses oder dergleichen transferierende Vorrichtung besonders einfach und montagetechnisch unproblematisch dadurch gestaltet ist, daß die getriebliche Verbindung zwischen der Antriebswelle 4 des Antriebsmotors und der Getriebeeinrichtung zur Umsetzung der rotatorischen in eine translatorische Bewegung auf einfachste Weise und ohne aufwendige Sachkenntnis hergestellt werden kann. Zu diesem Zwecke wird erfindungsgemäß eine Zahnradverbindung zwischen der Abtriebswelle 4 des Antriebsmotors und der Welle 14 vorgeschlagen, auf der koaxial das Zahnrad 16 und das Antriebsritzel 17 verdrehfest befestigt sind. Diese Zahnradverbindung wird durch radiale Zuführbe wegung der Einheit 8 in den Antriebskopf 2 in Eingriff gebracht, wobei das eine Zahnrad der Abtriebswelle 4 des Antriebsmotors und das damit kämmende Zahnrad 16 der vormontierten Einheit 8 in radialer Richtung aufeinander zu bewegt werden, bis die beiden Zahnräder 5, 16 miteinander kämmen. Ein besonderer Vorteil der erfindungsgemäßen Antriebsvorrichtung ist darin zu sehen, daß die vormontierte Einheit komplett mit Rollenkette werkseitig montiert werden kann und bei der Montage nur zwei Elemente, nämlich die vormontierte Einheit 8 und der Antriebskopf 2 beispielsweise im Garagendeckenbereich montiert werden müssen, wobei die Zuordnung der beiden Teile derart vereinfacht ist, daß die Montage auch von Laien ausgeführt werden kann.The drive device according to the invention thus represents a largely preassembled version which provides a gear connection between the drive motor and the door leaf or the like in a simple manner. The basic idea is particularly to be seen in the fact that a device which transfers the rotary drive movement of the drive motor into a translational drive movement of a building lock or the like is particularly simple and unproblematic in terms of assembly technology in that the gear connection between the drive shaft 4 of the drive motor and the transmission device for implementing the rotary in a translational movement can be produced in the simplest way and without extensive expertise. For this purpose, a gear connection between the output shaft 4 of the drive motor and the shaft 14 is proposed according to the invention, on which the gear 16 and the drive pinion 17 are fixed in a rotationally fixed manner. This gear connection is brought into engagement in the drive head 2 by radial feed movement of the unit 8, the one gear of the output shaft 4 of the drive motor and the meshing gear 16 of the preassembled unit 8 being moved towards one another in the radial direction until the two gear wheels 5 , 16 comb each other. A particular advantage of the drive device according to the invention can be seen in the fact that the preassembled unit can be completely assembled at the factory with a roller chain and only two elements, namely the preassembled unit 8 and the drive head 2, have to be installed in the garage ceiling area, for example, the assignment of Both parts are so simplified that the assembly can also be carried out by laymen.
