Description

Die Erfindung betrifft eine Hilfsantriebsvorrichtung zum hilfsweisen Antreiben eines mit einem Hauptantriebsaggregat antreibbaren Gebäudeverschlusses - insbesondere Tores wie Deckengliedertor oder Rolltor - mit einem mittels eines vorzugsweise manuell betätigbaren Zugmittels in umlaufende Drehung versetzbaren Hilfsantriebsdrehglied - wie Hilfsantriebsrad, Hilfsantriebswelle oder dergleichen -, das für den hilfsweisen Antrieb mit einem drehbaren Abgriffsdrehglied, das dem Antriebsstrang des Gebäudeverschlusses zugeordnet und zur gemeinsamen Drehung damit verbunden oder darin integriert ist, zum Abgriff der Hilfsantriebsdrehbewegung in Eingriff bringbar ist.The invention relates to an auxiliary drive device for auxiliary driving of a building lock which can be driven with a main drive unit - in particular gates such as a ceiling sectional door or roller shutter - with an auxiliary drive rotary member which can be set in rotation by means of a preferably manually operable traction means - such as auxiliary drive wheel, auxiliary drive shaft or the like - for the auxiliary drive a rotatable tapping rotary element, which is assigned to the drive train of the building lock and is connected to it or integrated therein for common rotation, can be brought into engagement for tapping the auxiliary drive rotary movement.

Hilfsantriebsvorrichtungen sind bei Torantrieben in Form von Nothandkettenantrieben bekannt. Sie dienen dazu, dass das ansonsten mit einem Elektromotor oder dergleichen betätigbare Tor auch bei Stromausfall geöffnet bzw. geschlossen werden kann. Hierzu sind sehr viele derzeit auf dem Markt befindlichen Wellenantriebe für Tore mit einem Hilfsantriebsdrehglied in Form eines Haspelkettenrades versehen, das mit einer Haspelkette oder Zugkette manuell in Drehung versetzbar ist. Das Haspelkettenrad ist mittels eines Abgriffsdrehglied in Form einer Kupplungseinrichtung mit dem Hauptantriebsstrang und zum Beispiel mit einer Torantriebswelle verbindbar. Ein Beispiel einer solchen Hilfsantriebsvorrichtung der eingangs genannten Art ist aus der DE 34 26 428 C2 bekannt, auf die für weitere konstruktive Einzelheiten ausdrücklich verwiesen wird. Bei dieser bekannten Hilfsantriebsvorrichtung ist mit dem Hilfsantriebsdrehglied in Form eines ortsfest gelagerten Haspelkettenrades eine Kupplungseinrichtung mit einem Ansatz, an dem schwenkbar ein Mitnehmer gelagert ist, der zur Kupplungsbetätigung in Ansätze an einer Motorwelle (Abgriffsdrehglied) einschwenken kann. Das Verschwenken geht über eine Kurven-Stift-Anordnung bei Drehen des Haspelkettenrades.Auxiliary drive devices are known for gate drives in the form of emergency hand chain drives. They are used so that the gate, which can otherwise be actuated by an electric motor or the like, can be opened or closed even in the event of a power failure. For this purpose, many shaft drives for gates currently on the market are provided with an auxiliary drive rotating member in the form of a reel sprocket, which can be manually rotated with a reel chain or pull chain. The reel sprocket can be connected to the main drive train and, for example, to a door drive shaft by means of a rotary tapping element in the form of a coupling device. An example of such an auxiliary drive device of the type mentioned is known from DE 34 26 428 C2, to which express reference is made for further structural details. In this known auxiliary drive device is with the auxiliary drive rotary member in the form of a stationary spool sprocket, a coupling device with an approach on which a driver is pivotally mounted, which swivel to actuate the clutch in approaches on a motor shaft (tapping rotary member) can. The pivoting takes place via a curve-pin arrangement when the reel sprocket is turned.

Nachteilig bei dieser und auch bei anderen, wie z.B. in der US-A-2 819 628 beschriebenen, bisher auf dem Markt befindlichen Nothandkettenantrieben ist ihr durch die Kupplungseinrichtung verursachter getriebetechnischer hoher Aufwand. Zudem weisen sie meist ein ungünstiges Übersetzungsverhältnis vor, da zum Beispiel das Haspelkettenrad wie bei der DE 34 26 428 C2 direkt an die Motorwelle angekuppelt wird, die aufgrund der meist verwendeten hochtourigen Elektromotoren entsprechend getriebemäßig übersetzt an die Torantriebswelle angeschlossen ist. Aufgrund dessen ist mit vielen derzeit auf dem Markt befindlichen Nothandkettenantrieben nur ein sehr langsames Heben und Senken des Tores möglich.A disadvantage of this and also of others, such as in US-A-2 819 628, previously available on the market emergency hand chain drives is the high level of effort in terms of transmission technology caused by the coupling device. In addition, they usually have an unfavorable transmission ratio, since, for example, the reel sprocket, as in DE 34 26 428 C2, is coupled directly to the motor shaft, which, due to the high-speed electric motors that are mostly used, is connected to the door drive shaft in a geared manner. Because of this, with many emergency hand chain drives currently on the market, only a very slow lifting and lowering of the door is possible.

Aufgabe der Erfindung ist es, eine Hilfsantriebsvorrichtung der eingangs genannten Art zu schaffen, die getriebetechnisch einfacher aufgebaut ist, wenig Platz beansprucht und dennoch eine für den jeweiligen Notbetrieb günstige Übersetzung bietet.The object of the invention is to provide an auxiliary drive device of the type mentioned, which is simpler in terms of transmission technology, takes up little space and yet offers a translation which is favorable for the respective emergency operation.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass das Hilfsantriebsdrehglied in einem relativ zum Abgriffsdrehglied - mit zumindest einer Bewegungskomponente parallel zu dessen Drehebene bewegbar gehaltenen Lagerglied derart gelagert ist, daß die in einer Ruhelage entkoppelten Drehglieder aus der Ruhelage heraus mit zumindest einer Bewegungskomponente in ihrer jeweiligen Drehebene relativ zueinander bewegbar und dabei über sich in ihrer Gesamtheit im wesentlichen in Umfangsrichtung an den Drehgliedern erstreckende Eingriffs- oder Verzahnungsbereiche zum Bilden eines Übersetzungsradgetriebes in vorzugsweise formschlüssigen Eingriff miteinander bringbar sind.This object is achieved according to the invention in that the auxiliary drive rotary member is mounted in a bearing member which is movable relative to the tap rotary member - with at least one movement component parallel to its rotational plane in such a way that the rotary members decoupled in a rest position from the rest position with at least one movement component in their respective rotational plane can be moved relative to one another and, in their entirety, can be brought into engagement with one another in a preferably form-fitting manner via engagement or toothing regions which extend in their entirety essentially in the circumferential direction on the rotary members.

Bei dem erfindungsgemäßen Hilfsantrieb sind also das Hilfsantriebsdrehglied - also zum Beispiel ein Haspelkettenrad oder ein damit integrales oder verbundenes Teil - und das Abgriffsdrehglied als Antriebsglied und Abtriebsglied eines Übersetzungsradgetriebes ausgebildet. Die beiden Drehglieder sind in ihrer jeweils radialen Richtung relativ zueinander beweglich und in einer Ruhestellung voneinander entkoppelt. Durch in der Drehebene zumindest eines der Drehglieder - vorzugsweise in der den beiden Drehgliedern gemeinsame Drehebene bei entsprechender Drehgliedanordnung - erfolgende Relativbewegung aufeinander zu werden sich umfangsmäßig erstreckende Bereiche der beiden Drehglieder in Eingriff gebracht und damit die beiden Drehglieder aneinander gekoppelt. Somit entfällt eine separate Kupplungseinrichtung zwischen Hilfsantriebsdrehglied und Hauptantriebsstrang. Zudem sind je nach Einsatz- oder Verwendungszweck über die Radien der Eingriffs- oder Verzahnungsbereiche, die jeweils durch die Relativbewegung aus der Ruhelage heraus in Eingriff miteinander bringbar sind, verschiedene Übersetzungsverhältnisse realisierbar. Die Eingriffs- oder Verzahnbereiche erstrecken sich im wesentlichen umfangsmäßig, es sind also auch geneigte Verzahnungsbereiche möglich. Dadurch, dass die Relativbewegung jeweils radial zu den beiden Drehgliedern erfolgt - d.h. zumindest mit einer radialen Komponente - wird eine platzraubende Axialverschiebung von Kopplungselementen vermieden.In the auxiliary drive according to the invention, the auxiliary drive rotary member - for example a reel sprocket or a part integral or connected therewith - and the tap rotary member are designed as the drive member and driven member of a transmission gear. The two rotary members are movable relative to each other in their respective radial directions and are decoupled from one another in a rest position. Areas of the two rotating members that extend around the circumference are brought into engagement by relative movement in the rotating plane of at least one of the rotating members, preferably in the rotating plane common to the two rotating members with a corresponding rotating member arrangement, and thus the two rotating members are coupled to one another. A separate coupling device between the auxiliary drive rotary element and the main drive train is thus dispensed with. In addition, depending on the intended use or intended use, the radii of the engagement or toothing areas are engaged by the relative movement from the rest position can be brought together, different gear ratios can be realized. The engagement or toothed areas extend essentially circumferentially, so inclined toothed areas are also possible. The fact that the relative movement takes place radially with respect to the two rotary members - ie at least with a radial component - avoids a space-consuming axial displacement of coupling elements.

Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.

Die Relativbewegung zwischen den beiden Drehgliedem wird in einfacher Weise realisiert, wenn das zur Lagerung des Hilfsantriebsdrehglied dienende Lagerglied relativ zum Abgriffsdrehglied um eine mit Abstand zu dessen Drehachse verlaufende Schwenkachse derart schwenkbar gelagert ist, dass die sich jeweils in Umfangsrichtung erstreckenden Eingriffsoder Verzahnungsbereiche durch Verschwenken des Lagergliedes aus dessen Ruhelage heraus in Eingriff bringbar sind. Eine besonders bevorzugte Ausgestaltung der Erfindung wird dabei dann erreicht, wenn die Schwenkachse in etwa parallel zur Drehachse des Hilfsantriebsdrehgliedes mit Abstand davon verläuft und eine Bremseinrichtung vorgesehen ist, die eine sich der Drehung des Hilfsantriebsdrehgliedes widersetzende Kraft auf das Hilfsantriebsdrehglied ausübt. Wenn bei einer solchen Ausbildung eine Zugkraft auf einen Strang des Zugmittels ausgeübt wird, so widersetzt sich das Hilfsantriebsdrehglied aufgrund der Bremseinrichtung zunächst der Drehung. Das Zusammenwirken der Bremseinrichtung mit dem Hilfsantriebsdrehglied wird dabei so gewählt, dass durch den Zug am Zugmittel zunächst die Schwenkbewegung des Lagergliedes eingeleitet wird, bis die beiden Drehglieder in Eingriff miteinander gelangen. Da sich bei vollständigem Eingriff der Drehlieder das Lagerglied nicht weiter verschwenken kann - was vorzugsweise noch durch eine Anschlageinrichtung zum Begrenzen der Verschwenkbewegung unterstützt wird -, wird ein weiter am Zugmittel ausgeübter Zug über den Eingriff des Zugmittels mit dem Hilfsantriebsdrehglied in Hilfsantriebsdrehbewegung umgesetzt. Da sich das Hilfsantriebsdrehglied in dieser Lage mit dem Abgriffsdrehglied in Eingriff befindet, wird dessen Drehbewegung über das Abgriffsdrehglied auf den Hauptantriebsstrang übertragen und somit der Gebäudeverschluß hilfsweise angetrieben. Damit ist durch einfache Handbetätigung, nämlich durch einfaches Ziehen am Zugmittel, ohne weitere Schritte gleichzeitig ein Einkuppeln der Hilfsantriebsvorrichtung und ein Drehen derselben erreichbar.The relative movement between the two rotary members is realized in a simple manner if the bearing member serving to support the auxiliary drive rotary member is pivotably mounted relative to the tapping rotary member about a pivot axis extending at a distance from its axis of rotation in such a way that the engagement or toothing regions extending in the circumferential direction in each case by pivoting the bearing member can be brought into engagement from its rest position. A particularly preferred embodiment of the invention is achieved when the pivot axis runs approximately parallel to the axis of rotation of the auxiliary drive rotary member at a distance therefrom and a braking device is provided which exerts a force on the auxiliary drive rotary member which opposes the rotation of the auxiliary drive rotary member. If a tractive force is exerted on a strand of the traction means in such a configuration, the auxiliary drive rotary member initially opposes the rotation due to the braking device. The interaction of the braking device with the auxiliary drive rotary member is selected so that the pivoting movement of the bearing member is initially initiated by the pull on the traction means until the two rotary members come into engagement with one another. Since the bearing member cannot pivot any further when the rotary members are fully engaged - which is preferably also supported by a stop device to limit the pivoting movement - a pull that is still exerted on the traction means is converted into auxiliary drive rotational movement via the engagement of the traction means with the auxiliary drive rotary element. Since the auxiliary drive rotary member is in engagement with the tap rotary member in this position, its rotational movement is transmitted via the tap rotary member to the main drive train and the building lock is thus driven in the alternative. A simple manual actuation, namely by simply pulling on the traction means, enables the auxiliary drive device to be engaged and rotated at the same time without further steps.

Diese Funktion wird durch Schwerkräfte dann noch unterstützt, wenn die Lagerung des Lagergliedes derart ist, dass die Drehachse des Hilfsantriebsgliedes oberhalb der Schwenkachse des Lagergliedes liegt. Mit "oberhalb" muss nicht genau lotrecht oberhalb gemeint sein, bevorzugt ist, wenn die Drehachse höher als die Schwenkachse liegt, so daß ein nach unten gerichteter Zug am Zugmittel eine nach unten gerichtete Verschwenkbewegung einleitet.This function is supported by gravity when the bearing of the bearing member is such that the axis of rotation of the auxiliary drive member is above the pivot axis of the bearing member. With "above" does not necessarily mean exactly above, is preferred if the axis of rotation is higher than the pivot axis, so that a downward pull on the traction device initiates a downward pivoting movement.

Um nach Ende des Hilfsantriebes eine Entkopplung der beiden Drehglieder in einfacher Weise zu ermöglichen, ist das Lagerglied gemäß bevorzugter Ausführung in seine Ruhestellung vorgespannt. Dies wäre im Prinzip auch durch Gewichtsanordnungen oder dergleichen möglich, bevorzugt ist aber zum Vorspannen wenigstens eine Federeinrichtung vorgesehen.In order to enable decoupling of the two rotary members in a simple manner after the end of the auxiliary drive, the bearing member is, according to a preferred embodiment, biased into its rest position. In principle, this would also be possible by means of weight arrangements or the like, but at least one spring device is preferably provided for pretensioning.

Wenn in bevorzugter Ausführung die bereits erwähnte Anschlageinrichtung zum Begrenzen der Relativbewegung, insbesondere der Verschwenkbewegung, vorgesehen ist, so ist ein Verklemmen der beiden Drehglieder durch zu hohe die Relativbewegung verursachende Kräfte verhindert. Die beiden Drehglieder könnten vielfältig ausgebildet sein, es wäre zum Beispiel eine Ausführung mit zwei verschiedenartig außenverzahnten Zahnritzeln denkbar. Eine sehr kompakte und hinsichtlich des Einkuppelvorganges sehr vorteilhafte Ausführungsform wird aber dann erreicht, wenn das Hilfsantriebsdrehglied einen ringförmigen Bereich aufweist, an dessen radial nach innen gerichteter Wandung der Eingriffs- oder Verzahnungsbereich des Hilfsantriebsdrehgliedes ausgebildet ist, wobei der ringförmige Bereich das an seinem Außenumfang mit seinem Eingriffs- oder Verzahnungsbereich versehene Abgriffsdrehglied umgibt und wobei der Innendurchmesser des ringförmigen Bereiches größer ist als der Außendurchmesser des Eingriffs- oder Verzahnungsbereich des Abgriffsdrehglieds. Durch diese Anordnung kann das durch Hilfsantriebsdrehglied und Abgriffsdrehglied gebildete Übersetzungsradgetriebe innerhalb des Hilfsantriebsdrehgliedes ausgebildet werden. Das Hilfsantriebsdrehglied weist den beispielsweise mit einer Innenverzahnung versehenen ringförmigen Bereich auf, der das Abgriffsdrehglied oder zumindest dessen Eingriffsoder Verzahnungsbereich umgibt. Das Hilfsantriebsdrehglied könnte also beispielsweise vollständig als Ring ausgebildet sein, möglich wäre aber auch eine Topfform oder dergleichen. Bevorzugt ist das Hilfsantriebsdrehglied eine zumindest bereichsweise ringförmige Zugmittelscheibe, insbesondere Kettenscheibe, oder mehr vorzugsweise ein zumindest bereichsweise ringförmiges Zugmittelrad, insbesondere Kettenrad, an welcher bzw. welchem das Zugmittel, zum Beispiel eine Kette, vorzugsweise zur Drehbewegungsübertragung in formschlüssigen Eingriff, geführt ist.If, in a preferred embodiment, the abovementioned stop device is provided for limiting the relative movement, in particular the pivoting movement, jamming of the two rotating members is prevented by excessive forces causing the relative movement. The two rotary links could be designed in a variety of ways, for example an embodiment with two differently externally toothed pinions would be conceivable. A very compact and very advantageous embodiment with regard to the engagement process is achieved, however, if the auxiliary drive rotary member has an annular area, on the radially inward wall of which the engagement or toothing area of the auxiliary drive rotary member is formed, the annular area having its outer circumference with its Surrounding engagement or toothing region surrounding tap rotary member and wherein the inner diameter of the annular region is larger than the outer diameter of the engagement or toothing region of the tap rotary member. With this arrangement, the transmission gear set formed by the auxiliary drive rotary member and the tap rotary member can be formed within the auxiliary drive rotary member. The auxiliary drive rotary member has the annular region, for example provided with internal toothing, which surrounds the tap rotary member or at least its engagement or toothed region. The auxiliary drive rotary member could thus, for example, be designed entirely as a ring, but a pot shape or the like would also be possible. The auxiliary drive rotary member is preferably an at least partially annular traction means disc, in particular a chain disc, or more preferably an at least partially ring-shaped traction means wheel, in particular a sprocket, on which the traction means, for example a chain, is guided in positive engagement, preferably for transmitting rotational movement.

Bisher auf dem Markt befindliche Nothandkettenantriebe müssen vielfach für Rechts- und Linkslauf, d.h. für "Tor auf" und "Tor zu" besonders eingekuppelt werden. Dies wird gemäß einer besonders bevorzugten Ausführungsform der Erfindung, die einen einfachen Ein- und Ausschaltmechanismus für den Rechts- und Linkslauf gewährleistet, vermieden. Hierzu ist bei dem das Abgriffsdrehglied umgebenden Hilfsantriebsdrehglied vorgesehen, daß das das Hilfsantriebsdrehglied lagernde Lagerglied aus seiner Ruhestellung wahlweise zum Rechtsoder Linkslauf nach beiden Seiten verschwenkbar ist, um die Drehglieder einerseits oder andererseits einer durch die Schwenkachse und die Drehachse des Hilfsantriebsdrehgliedes verlaufend gedachten Ebene in Eingriff oder Erfassung zu bringen. Die Ruhestellung kann dabei derart gewählt sein, dass die Drehachse des Abgriffdrehgliedes in dieser Ebene oder links oder rechts davon liegt, solange in der Ruhestellung die beiden Drehglieder entkoppelt sind. Eine gleichmäßige Umschaltung wird natürlich dann am ehesten erreicht, wenn in der Ruhestellung die Drehachse des Abgriffsdrehgliedes mit dieser gedachten Ebene zusammenfällt. In bevorzugter Ausführung sind in der Ruhestellung die Drehachsen der Drehglieder im wesentlichen zusammenfallend, d.h. die beiden Drehglieder liegen in Ruhestellung koaxial, insbesondere koaxial ineinander.Emergency hand chain drives previously on the market often have to be specifically coupled for clockwise and counterclockwise rotation, ie for "gate open" and "gate closed". This is avoided according to a particularly preferred embodiment of the invention, which ensures a simple switch-on and switch-off mechanism for clockwise and counter-clockwise rotation. This is in the case of the auxiliary drive rotary member surrounding the tap rotary member, the bearing member supporting the auxiliary drive rotary member can be pivoted from its rest position either to the right or to the left to either side, in order to engage or detect the rotary members on the one hand or, on the other hand, a plane running through the pivot axis and the axis of rotation of the auxiliary drive rotary member bring. The rest position can be selected in such a way that the axis of rotation of the tapping rotary member lies in this plane or to the left or right thereof, as long as the two rotary members are decoupled in the rest position. A smooth switchover is of course most likely to be achieved when the axis of rotation of the tapping rotary element coincides with this imaginary plane in the rest position. In a preferred embodiment, the axes of rotation of the rotary members are essentially coincident in the rest position, ie the two rotary members lie coaxially, in particular coaxially, in the rest position.

In bevorzugter Ausführung ist das Abgriffsdrehglied ein Zahnritzel, wobei der Eingriffsbereich des Hilfsantriebsdrehgliedes ebenfalls mit einer Verzahnung versehen ist. Letztere ist im Falle des zumindest bereichsweise ringförmigen Hilfsantriebsdrehgliedes vorzugsweise eine Innenverzahnung. Da die beiden Drehglieder in der als Relativbewegung eine Verschwenkbewegung ausführenden Ausgestaltung in einer bogenförmigen Relativbewegungsbahn ineinandergreifen, ist zum einwandfreien Eingreifen die Form der Verzahnungen besonders wesentlich. Bei ineinanderliegender Drehgliederanordnung bei in der gemeinsamen Drehebene verschwenkbar gelagertem Hilfsantriebsdrehglied wurden beste Eingriffsergebnisse mit Verzahnungen erreicht, wie sie in den beigefügten Figuren gezeigt sind. Demgemäß ist bevorzugt, dass die Verzahnungen im Querschnitt dreieckförmige Zähne, die bevorzugt mit Abstand voneinander angeordnet sind, aufweisen.In a preferred embodiment, the tapping rotary member is a toothed pinion, the engagement region of the auxiliary drive rotary member also being provided with a toothing. The latter is preferably an internal toothing in the case of the auxiliary drive rotary member which is at least partially ring-shaped. Since the two rotary members mesh with one another in an arc-shaped relative movement path in the embodiment which carries out a pivoting movement, the shape of the toothings is particularly important for correct engagement. In the case of an interlocking rotary link arrangement with an auxiliary drive rotary link pivotably mounted in the common rotary plane, the best engagement results with toothings were achieved, as shown in the attached figures. Accordingly, it is preferred that the teeth have triangular teeth in cross section, which are preferably arranged at a distance from one another.

Als Lagerglied kommt bevorzugt ein schwenkbar an einem ortsfesten, dem Hauptantriebsaggregat zugeordneten Aggregatgehäuse, insbesondere Getriebegehäuse, gelagertes zweiteiliges Gehäuse zum Einsatz, das radial äußere Bereiche des Hilfsantriebsdrehgliedes lagernd umfasst.The bearing member used is preferably a two-part housing which is pivotably mounted on a stationary unit housing, in particular gear housing, assigned to the main drive unit and which comprises radially outer regions of the auxiliary drive rotary member in a bearing manner.

Die Bremseinrichtung umfasst bevorzugt eine Wellscheibe oder gewellte Scheibe, Federscheibe oder dergleichen Reibelement zum Ausüben einer definierten Reibkraft auf das Hilfsantriebsdrehglied. In bevorzugter Ausführung ist die Bremsscheibe zwischen einem Teil des zweiteiligen Gehäuses und radialen Flächen, insbesondere Kreisflächen, des Hilfsantriebsgliedes angeordnet.The braking device preferably comprises a corrugated disk or corrugated disk, spring washer or similar friction element for exerting a defined frictional force on the auxiliary drive rotary member. In a preferred embodiment, the brake disc is arranged between a part of the two-part housing and radial surfaces, in particular circular surfaces, of the auxiliary drive member.

Um zu verhindern, dass das Hauptantriebsaggregat während des Nothandbetriebes plötzlich in Gang gerät und eventuell zu Verletzungen einer das Zugmittel betätigenden Person führt, ist eine weiter bevorzugte Ausgestaltung der Erfindung gekennzeichnet durch eine durch die Relativ- bzw. Verschwenkbewegung schaltbare Schalteinrichtung zum Außerbetriebsetzen oder Außerbetriebhalten des Hauptantriebsaggregates, wenn das Lagerglied aus seiner Ruhelage ausgelenkt bzw. verschwenkt ist.To prevent the main drive unit suddenly during emergency manual operation gets going and possibly leads to injuries to a person operating the traction means, a further preferred embodiment of the invention is characterized by a switchable by the relative or pivoting switching device for decommissioning or decommissioning of the main drive unit when the bearing member is deflected or pivoted from its rest position is.

In bevorzugter Ausgestaltung als Nothandkettenantrieb eines Torantriebes - insbesondere Wellentorantriebes - weist die erfindungsgemäße Hilfsantriebsvorrichtung als Hilfsantriebsdrehglied ein Haspelkettenrad mit einem Innenzahnkranz auf, das in einem schwenkbaren Gehäuse gelagert ist. Diese aus Haspelkettenrad und verschwenkbarem Gehäuse gebildete Einheit ist um einen Schwenkpunkt gegen ein auf der Motorwelle des Hauptantriebsaggregats angeordnetes Ritzel zur rechten bzw. linken Seite hin verschwenkbar. Die Verschwenkung des Gehäuses mit Haspelkettenrad geschieht dadurch, indem eine Zugkraft auf einen der Kettenstränge ausgeübt wird. Aufgrund einer axial an radialen Flächen des Haspelkettenrades angreifenden vorgegebenen definierten Reibkraft - durch Federscheibe oder dergleichen ausgeübt - entsteht beim Ziehen des Kettenstranges ein Schwenkmoment zum Verschwenken der Gehäuse-Haspelkettenradeinheit. Die Rückstellung dieser Einheit erfolgt insbesondere über Druckfedern, die die Einheit in ihre Ruhelage vorspannen.In a preferred embodiment as an emergency hand chain drive for a door drive - in particular a shaft door drive - the auxiliary drive device according to the invention has, as an auxiliary drive rotary member, a reel sprocket with an internal toothed ring, which is mounted in a pivotable housing. This unit, which consists of a sprocket sprocket and a pivotable housing, can be pivoted about a pivot point against a pinion arranged on the motor shaft of the main drive unit to the right or left side. The housing with the reel sprocket is pivoted by exerting a tensile force on one of the chain strands. Due to a predetermined, defined frictional force acting axially on radial surfaces of the reel sprocket - exerted by a spring washer or the like - when the chain strand is pulled, a pivoting moment arises for pivoting the housing reel sprocket unit. This unit is reset, in particular, by means of compression springs that pretension the unit into its rest position.

Beim Gesamtsystem sind die Lage des Schwenkpunktes, die Hebelverhältnisse im Eingriffsfall, die Zahnform des Zahnkranzes und des Ritzels, die Rückstellkraft der Druckfedem und Anschläge zur Begrenzung der Schwenkbewegung wichtig. Die hierdurch vorgegebenen einzelnen Parameter sind vom Fachmann leicht durch Versuche jeweils für den Einzelfall optimierbar. Außerdem ist auch noch die an dem Haspelkettenrad angreifende Reibkraft zu berücksichtigen und gegebenenfalls einzustellen. Die Rückstellkraft der Druckfedern und die Reibkraft am Haspelkettenrad bilden die Kriterien für die einwandfreie Schaltung.In the overall system, the position of the pivot point, the leverage in the event of an intervention, the tooth shape of the ring gear and the pinion, the restoring force of the compression springs and stops to limit the pivoting movement are important. The individual parameters specified in this way can easily be optimized by the person skilled in the art by trials for the individual case. In addition, the frictional force acting on the reel sprocket must also be taken into account and adjusted if necessary. The restoring force of the compression springs and the frictional force on the reel sprocket form the criteria for a perfect shift.

Eine Hilfsantriebsvorrichtung zum hilfsweisen Antreiben eines Wellentorantriebes weist ein Haspelkettenrad 12 mit darüber gelegter Endlosrundlaufkette 14 auf. Die Endlosrundlaufkette 14 ist über das Haspelkettenrad 12 geführt und greift dabei formschlüssig in ein Haspelkettenprofil 16 am Haspelkettenrad 12 ein. Das Haspelkettenrad 12 ist in einem das Haspelkettenrad 12 umgebenden zweiteiligen Gehäuse 18 gelagert. Das Gehäuse 18 ist mittels eines Schwenkbolzens 20 schwenkbar an einem Flanschdeckel 22 gelagert. Der Flanschdeckel 22 ist mittels Verschraubungen 24 oder dergleichen ortsfest an einem Getriebegehäuse 26 (siehe Figur 2) des Wellentorantriebes befestigt. Zwei links und rechts des Schwenkbolzens 20 angebrachte Druckfedern 28 spannen das zweiteilige Gehäuse 18 mit dem Haspelkettenrad 12 darin lagemäßig stabil mittig vor.An auxiliary drive device for auxiliary driving of a shaft gate drive has a reel sprocket 12 with an endless rotary chain 14 placed thereover. The endless circular chain 14 is guided over the reel sprocket 12 and thereby engages in a form-fitting manner in a reel chain profile 16 on the reel sprocket 12. The reel sprocket 12 is mounted in a two-part housing 18 surrounding the reel sprocket 12. The housing 18 is pivotally mounted on a flange cover 22 by means of a pivot pin 20. The flange cover 22 is fixed in place by means of screw connections 24 or the like to a gear housing 26 (see FIG. 2) of the shaft door drive. Two compression springs 28 attached to the left and right of the pivot pin 20 tension the two-part housing 18 with the reel sprocket 12 in a stable position in the center.

Das Haspelkettenrad 12 ist insgesamt ringförmig ausgebildet. An der Ringinnenwand 30 dieses Ringelements 12 ist eine Innenverzahnung 32 ausgebildet. Zwischen dem als Lagerglied für das Haspelkettenrad 12 dienenden Gehäuse 18 und dem Haspelkettenrad 12 ist ein Reibelement 34 als Bremseinrichtung vorgesehen. In dem dargestellten Beispiel greift das Reibelement 34 zwischen radial gerichteten Flächen des Haspelkettenrades und des Gehäuses 18 an. Das Reibelement 34 ist durch eine Wellscheibe, d.h. gewellte Scheibe, oder Federscheibe 36 gebildet.The reel sprocket 12 is generally ring-shaped. An internal toothing 32 is formed on the inner ring wall 30 of this ring element 12. A friction element 34 is provided as a braking device between the housing 18 serving as a bearing member for the reel sprocket 12 and the reel sprocket 12. In the example shown, the friction element 34 engages between radially directed surfaces of the reel sprocket and the housing 18. The friction element 34 is through a corrugated disc, i.e. corrugated washer, or spring washer 36 formed.

Im vom Haspelkettenrad 12 und dessen Innenverzahnung 32 umgebenen Raum 38 ist ein Zahnritzel 40 angeordnet. Das Zahnritzel 40 ist zur gemeinsamen Drehung mit einer Ritzelwelle 42 verbunden, die mit dem Hauptantriebsstrang des Torantriebes verbunden ist. Hierzu durchgreift die Zahnritzelwelle 42 das Getriebegehäuse 26 und ist im Innenraum desselben an ein Schneckenrad 44 eines Zahnradgetriebes angeflanscht.A toothed pinion 40 is arranged in the space 38 surrounded by the chain sprocket 12 and its internal toothing 32. The pinion 40 is connected for common rotation with a pinion shaft 42 which is connected to the main drive train of the door drive. For this purpose, the pinion shaft 42 extends through the gear housing 26 and is flanged to a worm wheel 44 of a gear transmission in the interior thereof.

Weiter ist eine Anschlageinrichtung zum Begrenzen der Verschwenkbewegung der aus dem Gehäuse 18 und dem Haspelkettenrad 12 gebildeten Einheit - Schwenkeinheit 21 - vorgesehen. Zur Bildung der Anschlageinrichtung ist der Flanschdeckel 22 mit einem Vorsprung 46 versehen, an dem zwei Anschlagsflächen 48 ausgebildet sind.Furthermore, a stop device is provided for limiting the pivoting movement of the unit - pivot unit 21 - formed from the housing 18 and the reel sprocket 12. To form the stop device, the flange cover 22 is provided with a projection 46 on which two stop surfaces 48 are formed.

An dem Flanschdeckel 22 ist außerdem ein Schalter 50 vorgesehen, der in den Stromversorgungsschaltkreis des Motoraggregates des Torantriebes geschaltet ist und bei Betätigung durch Drücken eines Schaltgliedes 52 das Motorantriebsaggregat (nicht gezeigt) stromlos schaltet oder stromlos hält. An dem dem Schwenkbolzen 20 entgegengesetzten Ende ist das als Lagerglied fungierende Gehäuse 18 mit einer Schaltfläche 54 zum Schalten des Schalters 50 versehen.A switch 50 is also provided on the flange cover 22, which switch is connected to the power supply circuit of the motor unit of the door drive and, when actuated by pressing a switching element 52, switches the motor drive unit (not shown) or keeps it currentless. At the end opposite the pivot pin 20, the housing 18 functioning as a bearing member is provided with a button 54 for switching the switch 50.

Die Schaltfläche 54 weist mittig eine Vertiefung 56 auf, die derart mit dem Schaltglied 52 des Schalters 50 korrespondiert, dass in der in den Figuren 1 und 2 gezeigten, durch die Druckfedern 28 aufrechterhaltenen stabilen mittigen Ruhelage des Gehäuses 18 und des Haspelkettenrades 12 das Schaltglied 52 unbetätigt bleibt.The button 54 has a recess 56 in the center, which corresponds to the switching element 52 of the switch 50 in such a way that the switching element 52 in the stable central rest position of the housing 18 and the reel sprocket 12 shown in FIGS. 1 and 2, which is maintained by the compression springs 28 remains inactive.

Die Innenverzahnung 32 des Haspelkettenrades 12 weist regelmäßig über den Umfang verteilte beabstandete im Querschnitt dreieckförmige Zähne 60 auf. Die Zähne 60 erstrecken sich in axialer Richtung über den gesamten die Innenverzahnung 32 bildenden Verzahnungsbereich 62. Die Außenverzahnung 64 des Zahnritzels 40 ist korrespondierend dazu ausgebildet, erstreckt sich in axialer Richtung über den gesamten Außenverzahnungsbereich und weist sich axial erstreckende rippenartige Zähne 66 mit dreieckförmigem Querschnitt und Abständen 68 dazwischen auf.The internal toothing 32 of the reel sprocket 12 has regularly spaced, triangular-shaped teeth 60 distributed over the circumference. The teeth 60 extend in the axial direction over the entire toothed area 62 forming the inner toothing 32. The outer toothing 64 of the toothed pinion 40 is designed to correspond thereto, extends in the axial direction over the entire outer toothed area and has axially extending rib-like teeth 66 with a triangular cross section and Spaces 68 in between.

In der in Figur 1 gezeigten Ruhestellung liegt die Drehachse des Zahnritzels 40 in einer durch die durch den Schwenkbolzen 20 gebildete Schwenkachse S und die Drehachse des Haspelkettenrades 12 verlaufend gedachten Ebene E (Schnittebene von Figur 2). In der gezeigten Ausführung fallen die Drehachsen D1 und D2 des Haspelkettenrades 12 und des Zahnritzels 40 in dieser Ruhestellung aufeinander - die beiden Drehglieder 12, 40 sind also koaxial zueinander angeordnet. Durch Verschwenken des Gehäuses 18 sind das Ritzel 40 und das Haspelkettenrad 12 wie in Figur 3 verdeutlicht in Eingriff bringbar. Die Zahnflanken der Zähne 60 und 66 sind dabei derart geneigt, dass sie bei diesem Eingriff im tangentialen Berührungsbereich 70 korrespondierend zueinander ausgebildet sind. Bei der gezeigten, eine zweiseitige Verschwenkung ermöglichenden Ausführung sind auch die jeweils entgegengesetzten Zahnflanken für den andersseitigen Eingriff bei entgegengesetzter Haspelkettenraddrehung entsprechend ausgebildet.In the rest position shown in FIG. 1, the axis of rotation of the toothed pinion 40 lies in a plane E (cutting plane of FIG. 2) that is intended to run through the pivot axis S formed by the pivot pin 20 and the axis of rotation of the reel sprocket 12. In the embodiment shown, the axes of rotation D 1 and D 2 of the reel sprocket 12 and the pinion 40 coincide in this rest position - the two rotating members 12, 40 are thus arranged coaxially to one another. By pivoting the housing 18, the pinion 40 and the reel sprocket 12 can be brought into engagement as illustrated in FIG. 3. The tooth flanks of the teeth 60 and 66 are inclined in such a way that they are designed to correspond to one another in the tangential contact region 70 during this engagement. In the embodiment shown, which enables a two-sided pivoting, the respectively opposite tooth flanks are designed accordingly for the engagement on the other side when the reel sprocket wheel rotates in the opposite direction.

Im folgenden wird die Funktion der Hilfsantriebsvorrichtung beschrieben. Wird an der Haspelkette oder Endlosrundlaufkette 14 gezogen, so widersetzt sich das Haspelkettenrad aufgrund der Bremswirkung des Reibelements 34, das eine definierte Reibkraft auf das Haspelkettenrad 12 ausübt, zunächst der Drehbewegung. Die Zugkraft an der Endlosrundlaufkette bewirkt dann zunächst ein Schwenkmoment, das ein Verschwenken des als Lagerglied des Haspelkettenrades 12 dienenden Gehäuses 18 bewirkt. Der Verzahnungsbereich 32 und der die Außenverzahnung 64 aufweisende Umfangsbereich des Zahnritzels 40 und damit die Zähne 66, 60 werden durch die Verschwenkbewegung in Eingriff gebracht. Bei Weiterziehen an dem Kettenstrang der Endlosrundlaufkette 14 wird die definierte Reibkraft dann überwunden und das Haspelkettenrad 12 beginnt sich zusammen mit dem darin in Eingriff befindlichen Zahnritzel 40 zu drehen. Dabei verhindern die Anschlagflächen 48 zwischen dem Gehäuse 18 und dem Flanschdeckel 22 ein Verklemmen der Zahnradpaarung. Bei Nachlassen der Zugkraft an der Haspelkette oder Endlosrundlaufkette 14 drückt die jeweilige Druckfeder 28 das Gehäuse 18 wieder in seine in den Figuren 1 und 2 gezeigte mittige Ruhelage; das Zahnradpaar 12, 40 wird dadurch wieder getrennt.The operation of the auxiliary drive device will now be described. If the reel chain or endless rotary chain 14 is pulled, the reel sprocket initially opposes the rotary movement due to the braking effect of the friction element 34, which exerts a defined frictional force on the reel sprocket 12. The tensile force on the endless rotary chain then initially causes a pivoting moment, which causes the housing 18 serving as a bearing member of the reel sprocket 12 to pivot. The toothing region 32 and the peripheral region of the toothed pinion 40, which has the external toothing 64, and thus the teeth 66, 60 are brought into engagement by the pivoting movement. When the chain strand of the endless rotary chain 14 is pulled further, the defined frictional force is then overcome and the reel sprocket 12 begins together with that which is engaged therein To rotate pinion 40. The stop surfaces 48 between the housing 18 and the flange cover 22 prevent the gear pair from jamming. When the tensile force on the reel chain or endless rotary chain 14 decreases, the respective compression spring 28 presses the housing 18 back into its central rest position shown in FIGS. 1 and 2; the gear pair 12, 40 is separated again.

Bei Verschwenken des Gehäuses 18 gelangt das Schaltglied 52 des Schalters 50 aus der Kerbe oder Vertiefung 56 und wird durch die Schaltfläche 54 betätigt, wodurch die Stromzufuhr zum Motorantriebsaggregat bei Betätigung der Hilfsantriebsvorrichtung unterbrochen wird.When the housing 18 is pivoted, the switching element 52 of the switch 50 comes out of the notch or depression 56 and is actuated by the button 54, as a result of which the power supply to the motor drive unit is interrupted when the auxiliary drive device is actuated.

Es ist also eine Hilfsantriebsvorrichtung - insbesondere für einen Torantrieb - beschrieben worden, bei der um ein Zahnritzel 40 mit sich umfangsmäßig erstreckender Außenverzahnung 64 ein zweiteiliges Gehäuse 18 mit eingelagertem Haspelkettenrad 12, das über eine Innenverzahnung 32 und ein Haspelkettenprofil 16 verfügt und als Hilfsantriebsdrehglied wirkt, um eine Schwenkachse S schwenkbar angeordnet. Das aus Gehäuse 18 und Haspelkettenrad 12 gebildete System - Verschwenkeinheit 21 - ist schwenkbar an einem Flanschdeckel 22 aufgebaut, der ortsfest am Getriebegehäuse 26 angeschraubt ist. Über zwei Druckfedern 28 wird die Verschwenkeinheit 21 lagemäßig stabil mittig gehalten. Das Zahnritzel 40 steckt drehfest mit seiner Ritzelwelle 42 in einem Schneckenrad 44 eines Torantriebsgetriebes. Die Haspelkette oder Endlosrundlaufkette 14 ist abgespreitzt tangential im zweiteiligen Gehäuse 18 verdrehsicher - formschlüssig - um das Haspelkettenrad 12 geführt. Zwischen dem Gehäuseoberteil 72 - dem einen Teil des zweiteiligen Gehäuses 18 - und dem Haspelkettenrad 12 ist an den sich berührenden Kreisringflächen eine Wellscheibe 36 zur Erzeugung einer definierten Reibkraft angeordnet. Wird an der Haspelkette oder Endlosrundlaufkette 14 gezogen, neigt sich das Gehäuse 18 mit dem Haspelkettenrad 12 gegen das Zahnritzel 40; die Zähne 60, 66 greifen ineinander.An auxiliary drive device - in particular for a door drive - has therefore been described, in which a two-part housing 18 with an inserted reel sprocket 12, which has an inner toothing 32 and a reel chain profile 16 and acts as an auxiliary drive rotary member, around a toothed pinion 40 with circumferentially extending external toothing 64, arranged to be pivotable about a pivot axis S. The system formed by the housing 18 and the reel sprocket 12 - pivoting unit 21 - is pivotally constructed on a flange cover 22 which is screwed onto the gear housing 26 in a fixed position. The pivoting unit 21 is held in a stable position in the center by means of two compression springs 28. The pinion 40 is rotationally fixed with its pinion shaft 42 in a worm wheel 44 of a door drive gear. The reel chain or endless rotary chain 14 is spouted tangentially in the two-part housing 18 so that it can rotate around the reel sprocket 12 in a form-fitting manner. Between the upper housing part 72 - one part of the two-part housing 18 - and the reel sprocket 12, a corrugated washer 36 is arranged on the circular ring surfaces touching to generate a defined frictional force. If the reel chain or endless rotary chain 14 is pulled, the housing 18 inclines with the reel sprocket 12 against the pinion 40; the teeth 60, 66 interlock.

Verschiedene Abwandlungen von der gezeigten Ausführungsform sind denkbar. Anstelle einer zweiseitigen Verschwenkmöglichkeit könnte auch nur eine einseitige Verschwenkmöglichkeit vorgesehen sein. Das Haspelkettenrad könnte auch mit einer Außenverzahnung versehen sein und in ein außerhalb desselben angeordnetes Zahnritzel durch Verschwenkbewegung eingreifbar ausgebildet sein.Different modifications of the embodiment shown are conceivable. Instead of a two-sided pivoting option, only a one-sided pivoting option could also be provided. The reel sprocket could also be provided with an external toothing and be designed so that it can be engaged by a pivoting movement in a toothed pinion arranged outside the same.

Einige Aspekte der hier beschriebenen Hilfsantriebsvorrichtung werden im folgenden anhand der Darstellung von Figur 1 noch einmal zusammengefasst:Some aspects of the auxiliary drive device described here are summarized again below with reference to the illustration in FIG. 1:

Die Erfindung betrifft eine Hilfsantriebsvorrichtung (10) zum hilfsweisen Antreiben eines mit einem Hauptantriebsaggregat antreibbaren Gebäudeverschlusses - insbesondere Tor wie Deckengliedertor oder Rolltor - mit einem mittels eines vorzugsweise manuell betätigbaren Zugmittels (14) in Drehung versetzbaren Hilfsantriebsdrehglied (12), das für den hilfsweisen Antrieb mit einem drehbaren Abgriffsdrehglied (40), das dem Hauptantriebsstrang des Gebäudeverschlusses zugeordnet und zur gemeinsamen Drehung damit verbunden oder darin integriert ist, zum Abgriff der Hilfsantriebsdrehbewegung in Eingriff bringbar ist. Um einen kompakten, getriebetechnisch einfachen und leicht zu bedienenden Aufbau zu schaffen wird vorgeschlagen, dass das Hilfsantriebsdrehglied (12) in einem relativ zum Abgriffsdrehglied (40) - mit zumindest einer Bewegungskomponente - parallel zu dessen Drehebene bewegbar gehaltenen Lagerglied (18) derart gelagert ist, dass die in einer Ruhelage entkoppelten Drehglieder (12, 40) aus der Ruhelage heraus mit zumindest einer Bewegungskomponente parallel zu deren Drehebene relativ zueinander bewegbar und dabei Ober sich in ihrer Gesamtheit im wesentlichen in Umfangsrichtung an den Drehgliedern (12, 40) erstreckenden Eingriffs- oder Verzahnungsbereiche (62, 64) zum Bilden eines Übersetzungsradgetriebes in vorzugsweise formschlüssigen Eingriff miteinander bringbar sind.The invention relates to an auxiliary drive device (10) for auxiliary driving of a building lock which can be driven with a main drive unit - in particular a gate such as a ceiling sectional door or a roller shutter - with an auxiliary drive rotary member (12) which can be rotated by means of a preferably manually operated traction means (14) and which is used for the auxiliary drive a rotatable tap rotary member (40), which is associated with the main drive train of the building lock and is connected to or integrated therein for common rotation, for engaging the auxiliary drive rotary movement. In order to create a compact, technically simple and easy-to-use construction, it is proposed that the auxiliary drive rotary member (12) be mounted in a bearing member (18) that is movable relative to the tap rotary member (40) - with at least one movement component - parallel to its rotational plane, that the rotating members (12, 40) decoupled in a resting position can be moved out of the resting position with at least one movement component parallel to their rotational plane relative to one another and thereby engaging or extending in their entirety essentially in the circumferential direction on the rotating members (12, 40) Gearing areas (62, 64) for forming a transmission gear can preferably be brought into positive engagement with one another.
