Eine derartige Antriebsvorrichtung für eine Schranke ist aus DE-U-76 09 915 bekannt. Dabei ist ein Ständer für die Schranke und ihren Antrieb vorgesehen, der nach Anbringung einer entsprechenden Verkleidung gleichzeitig selbst auch das Gehäuse für den Antrieb der Schranke bildet. Der Ständer weist eine Standplatte auf, auf der auch die Verkleidung im Gebrauchszustand aufsitzt.Such a drive device for a barrier is known from DE-U-76 09 915. A stand is provided for the barrier and its drive, which at the same time also forms the housing for the drive of the barrier after attaching a corresponding covering. The stand has a base plate on which the cladding also sits when in use.

In der DE-B-22 54 231 wird ein Antrieb für Türen beschrieben, der aber auch für Schranken oder sonstige Schwenkteile, beispielsweise Sperren an Skiliftzugängen anwendbar ist. Insbesondere der dort beschriebene Motor mit Schwenkarmen und Hebeln und einem dazwischen geschalteten Getriebe entspricht dem eingangs erwähnten Antriebsmotor mit entsprechenden Übertragungsmitteln.DE-B-22 54 231 describes a drive for doors, but it can also be used for barriers or other swivel parts, for example locks on ski lift accesses. In particular, the motor described there with swivel arms and levers and an interposed gear corresponds to the drive motor mentioned at the beginning with corresponding transmission means.

Nachteilig ist bei diesen bekannten Antrieben bisher der Aufwand bei der Befestigung der einzelnen wesentlichen Bestandteile der Antriebsvorrichtungen an den verschiedenen Tragteilen. Vor allem beim Einbau dieser Antriebsvorrichtungen in eine Schranke müssen diese Teile und die Träger in einen entsprechenden Pfosten der Schranke installiert werden oder der Ständer muß als Pfosten montiert und mit einer Verkleidung versehen werden, woraus auch eine entsprechende Mindestgröße dieser Teile folgt und Montagetüren für die Wartung der Antriebsaggregate benötigt werden. Darüber hinaus ergibt sich ein relativ schweres und in seinen Abmessungen großes Gehäuse- oder Ständerteil mit Antriebseinrichtung, falls dieses Aggregat bereits in einem Herstellungswerk montiert werden soll oder aber es entsteht ein entsprechend großer Montageaufwand am Einsatzort dieser Schranke oder eines sonstigen anzutreibenden Schwenkteiles.A disadvantage of these known drives has so far been the effort involved in fastening the individual essential components of the drive devices to the various supporting parts. Especially when installing these drive devices in a barrier, these parts and the supports must be installed in a corresponding post of the barrier or the stand must be mounted as a post and provided with a cladding, which also results in a corresponding minimum size of these parts and assembly doors for maintenance of the drive units are required. In addition, there is a relatively heavy and large dimensions housing or stand part with drive device, if this unit is already to be assembled in a manufacturing plant or there is a correspondingly large amount of assembly work at the location of this barrier or other pivoting part to be driven.

Es besteht deshalb die Aufgabe, eine Antriebsvorrichtung der eingangs erwähnten Art zu schaffen, die platzsparend gestaltet ist, eine weitgehend beliebige Form eines sie aufnehmenden Gehäuses oder einer sie aufnehmenden Halterung oder dergleichen erlaubt und dennoch einfach transportierbar und montierbar sowie reparaturfreundlich ist.There is therefore the task of creating a drive device of the type mentioned at the outset which is space-saving is a largely arbitrary shape of a housing accommodating it or a holder or the like accommodating it, and yet it is easy to transport and assemble and is easy to repair.

Eine erste Lösung dieser Aufgabe besteht darin, daß das Tragteil gehäuseunabhängig und als ganzes montierbar ist, einen U-förmigen Querschnitt hat, wobei der Quersteg die Tragplatte für den Motor bildet und die beiden Schenkel die Flansche für die Lagerung der Abtriebswelle sind, und daß etwa in Fortsetzung der parallelen Flansche Verlängerungen vorgesehen sind, die gegenüber den Flanschen nach der entgegengesetzten Seite der Halteplatte überstehen, und daß die Verlängerungen eine Halterung für die Federenden tragen.A first solution to this problem is that the support part is independent of the housing and can be assembled as a whole, has a U-shaped cross section, the crossbar forms the support plate for the motor and the two legs are the flanges for the mounting of the output shaft, and that approximately extensions of the parallel flanges are provided which protrude from the flanges on the opposite side of the holding plate, and that the extensions carry a holder for the spring ends.

Dadurch werden die Gesamtabmessungen der Antriebsvorrichtung verringert und die gesamte Antriebsvorrichtung wird sehr kompakt und platzsparend. Darüber hinaus kann das eigentliche, diese Antriebsvorrichtung aufnehmende Teil unabhängig von der Antriebsvorrichtung gestaltet sein und braucht nur Gegenbefestigungsstellen, die zu denen des Tragteiles passen. Somit ist auch ein Architekt in der Gestaltung freier. Darüber hinaus kann die Antriebsvorrichtung schon vormontiert sein und im Reparaturfall kann sie unter Umständen insgesamt sehr schnell demontiert und dann repariert werden, wobei im Falle längerer Reparaturen unter Umständen sogar eine Ersatz-Antriebsvorrichtung installiert werden kann.As a result, the overall dimensions of the drive device are reduced and the entire drive device becomes very compact and space-saving. In addition, the actual part accommodating this drive device can be designed independently of the drive device and only needs counter-fastening points that match those of the support part. Thus, an architect is also freer in the design. In addition, the drive device can already be preassembled and, in the event of a repair, it can, under certain circumstances, be dismantled very quickly and then repaired, and in the case of longer repairs, a replacement drive device can even be installed under certain circumstances.

Die parallelen und rechtwinklig zu der Tragplatte stehenden Flansche ergeben ein kompaktes und leicht zu handhabendes Tragteil, an welchem dennoch die einzelnen Antriebsaggregate leicht und sicher angebracht werden können. Die Verlängerungen in Fortsetzung der Flansche erlauben die Anbringung relativ langer und entsprechend starker Federn. Der U-förmige Tragteil wird durch diese Verlängerungen also um gegenüber dem U-Quersteg nach der entgegengesetzten Seite der Schenkel vorstehende Haltemittel ergänzt.The parallel flanges, which are perpendicular to the support plate, result in a compact and easy-to-use support part, to which the individual drive units can nevertheless be attached easily and securely. The extensions in continuation of the flanges allow the installation of relatively long and correspondingly strong springs. The U-shaped support part is thus opposite to these extensions the U-cross bar on the opposite side of the legs protruding holding means added.

Eine zweite Lösung der Aufgabe besteht darin, daß das Tragteil gehäuseunabhängig und als ganzes montierbar ist, einen U-förmigen Querschnitt hat, wobei der Quersteg die Tragplatte für den Motor bildet und die beiden Schenkel die Flansche für die Lagerung der Abtriebswelle sind und daß die Feder als über mindestens einen Teil der Länge der Abtriebswelle reichende Wickelfeder ausgebildet ist, deren Windungen mit radialem Abstand oder Spiel um die Abtriebswelle verlaufen.A second solution to the problem is that the support part is independent of the housing and can be assembled as a whole, has a U-shaped cross section, the crossbar forms the support plate for the motor and the two legs are the flanges for the mounting of the output shaft and that the spring is designed as a coil spring extending over at least part of the length of the output shaft, the windings of which run around the output shaft with radial spacing or play.

Dabei ergeben sich dieselben Vorteile wie bei der ersten Lösung, jedoch können die die Flansche fortsetzenden Verlängerungen entfallen, so daß die Antriebsvorrichtung noch kompakter und platzsparender wird.The same advantages result as in the first solution, but the extensions which continue the flanges can be dispensed with, so that the drive device becomes even more compact and space-saving.

Eine Ausgestaltung der ersten erfindungsgemäßen Lösung kann darin bestehen, daß der Querschnitt des Tragteiles durch die Verlängerungen zu einem H-förmigen Querschnitt ergänzt ist und die gegenüber der Tragplatte auf der Seite der Motoranbringung vorstehenden Stege dieses Querschnittes das Widerlager für die Federenden und gegebenenfalls die Lagerung für das Antriebs-Hebelsystem des Antriebsmotors aufweisen. Dadurch kann zwischen dem Motor und der Abtriebswelle sowie außerdem zwischen der Abtriebswelle und der Halterung der Rückstellfedern oder dergleichen ein größerer Abstand erzeugt werden, wobei aber dennoch der Vorteil erhalten bleibt, daß das so ausgestaltete Tragteil kompakt ist und eine Vormontage der Antriebsaggregate erlaubt, wonach es dann an einem entsprechenden Einsatzort befestigt werden kann. Das Tragteil mit Motor, Abtriebswelle, Antrieb der Abtriebswelle und Federn kann also als Fertigteil vormontiert sein. Dadurch beeinflußt es auch nicht oder kaum die Gestaltung im Bereich des anzutreibenden Schwenkteiles. Dieser Vorteil eines als Fertigteil vormontierten Tragteiles ergibt sich auch bei der zweiten erfindungsgemäßen Lösung und deren Ausgestaltungen gemäß den Ansprüchen 14 u. 15.An embodiment of the first solution according to the invention can consist in that the cross-section of the support part is supplemented by the extensions to an H-shaped cross-section and the webs of this cross-section projecting from the support plate on the side of the motor attachment provide the abutment for the spring ends and optionally the bearing for have the drive lever system of the drive motor. As a result, a greater distance can be generated between the motor and the output shaft and also between the output shaft and the holder of the return springs or the like, but still has the advantage that the supporting part designed in this way is compact and allows the drive units to be preassembled, after which it is can then be attached to an appropriate location. The support part with motor, output shaft, drive of the output shaft and springs can thus be pre-assembled as a finished part. As a result, it has little or no influence on the design in the area of the pivoting part to be driven. This advantage one as Pre-assembled support part also results in the second solution according to the invention and its configurations according to claims 14 u. 15.

Weitere Ausgestaltungen der ersten Lösung sind Gegenstand der Ansprüche 3 bis 13.Further refinements of the first solution are the subject of claims 3 to 13.

Vor allem bei Kombination einzelner oder mehrerer der vorbeschriebenen sowie der in den weiteren Ansprüchen enthaltenen Merkmale und Einzelheiten ergibt sich eine Antriebsvorrichtung für ein schwenkbares Teil, die platzsparend und kompakt und ohne Beeinflussung der Gestaltung des sie letzlich aufnehmenden Gehäuses ist und die in vorteilhafter Weise vormontiert angeliefert werden kann und aufgrund ihrer leichten Demontierbarkeit auch reparaturfreundlich ist. Dabei kann diese Antriebsvorrichtung nicht nur für Schranken, sondern auch für Sperrbügel für Supermärkte, Skilifte oder sonstige Zutrittskontrollen verwendet werden, wo ein motorisches Öffnen durch Knopfdruck, mit Hilfe von Codekarten oder durch Einwurf von Münzen od.dgl. erwünscht ist. Eine weitere zweckmäßige Anwendung ist die Betätigung von Türen, Toren oder Klappen mit dem Vorteil des automatischen Schließens durch die eingebauten Federn bei Stromausfall oder im Falle von Feuerschutztüren bei Brand. Vor allem beim Einsatz als Schrankenantrieb läßt sich dabei das Hebelsystem an dem Tragteil mit Hilfe von Anschlägen mechanisch blockieren, solange der Motor unter Spannung steht, während dieses Hebelsystem aber bei Stromausfall für eine Handbetätigung frei wird oder ― falls gewünscht ― durch die Federn ein automatisches Öffnen erfolgen kann.Especially when combining one or more of the above and those contained in the other claims Features and details result in a drive device for a pivotable part, which is space-saving and compact and without influencing the design of the housing which finally accommodates it, and which can advantageously be delivered preassembled and, due to its ease of disassembly, is also easy to repair. This drive device can be used not only for barriers, but also for locking bars for supermarkets, ski lifts or other access controls where motorized opening by pressing a button, using code cards or by inserting coins or the like. is desired. Another useful application is the actuation of doors, gates or flaps with the advantage of automatic closing by the built-in springs in the event of a power failure or in the case of fire protection doors in the event of fire. Especially when used as a barrier drive, the lever system on the supporting part can be mechanically blocked with the help of stops, as long as the motor is live, while this lever system is free for manual operation in the event of a power failure or - if desired - automatic opening by the springs can be done.

Eine im ganzen mit 1 bezeichnete Antriebsvorrichtung, im folgenden auch kurz "Vorrichtung 1" genannt, dient dazu, ein schwenkbares Teil 2 von einer Endlage (Fig. 1) in eine andere Endlage (Fig. 2) und umgekehrt zu verschwenken. Das schwenkbare Teil 2 des Ausführungsbeispieles könnte beispielsweise die Halterung für einen aus einer horizontalen Lage (Fig. 1) in eine etwa vertikale Lage (Fig. 2 und 6 bis 8) schwenkbaren Schrankenbaum 3 sein. Dies gilt dann, wenn die Vorrichtung 1 die in Fig. 1, 2, 3 sowie den Figuren 6 bis 8 dargestellte, im folgenden noch näher zu beschreibende Lage einnimmt. Wäre allerdings Fig. 1 und 2 eine Draufsicht der Vorrichtung, wäre sie in dieser Form auch anwendbar für solche Schranken, bei denen der Schlagbaum in einer etwa horizontalen Ebene verschwenkt wird. Ferner könnte die Vorrichtung 1 dann zum Betätigen von Sperrbügeln an Supermärkten, Skiliften od.dgl. oder zum Betätigen von Schwenktüren dienen. Mit anderen Worten, die Vorrichtung 1 kann in praktisch beliebiger Orientierung je nach Anwendungsfall angeordnet werden, wobei unter Umständen sogar auch eine umgekehrte Anordnung für abwärts schwenkbare Teile denkbar wäre.A drive device, generally designated 1, hereinafter also referred to as "device 1", serves to pivot a pivotable part 2 from one end position (FIG. 1) to another end position (FIG. 2) and vice versa. The pivotable part 2 of the exemplary embodiment could, for example, be the holder for a barrier boom 3 which can be pivoted from a horizontal position (FIG. 1) into an approximately vertical position (FIGS. 2 and 6 to 8). This applies when the device 1 is the one shown in FIGS. 1, 2, 3 and FIGS. 6 to 8, to be described in more detail below Takes position. However, if FIGS. 1 and 2 were a top view of the device, it would also be applicable in this form for barriers in which the barrier is pivoted in an approximately horizontal plane. Furthermore, the device 1 could then be used to actuate locking bars at supermarkets, ski lifts or the like. or serve to operate swing doors. In other words, the device 1 can be arranged in practically any orientation depending on the application, and in some circumstances even an inverted arrangement for parts which can be pivoted downwards would also be conceivable.

Die Antriebsvorrichtung 1 weist einen Antriebsmotor 4, eine Abtriebswelle 5, im Ausführungsbeispiel die den Schrankenarm 3 und das Schwenkteil 2 tragende Abtriebswelle 5, sowie Ausgleichs- oder Rückstell- oder Schließfedern 6 für das Schwenkteil 2 auf, die im Ausführungsbeispiel bei der Schließlage der Schranke gemäß Fig. 1 gespannt sind und die Offenstellung der Schranke unterstützen, also sie auch bei Stromausfall des Motors offenhalten können.The drive device 1 has a drive motor 4, an output shaft 5, in the exemplary embodiment the output shaft 5 carrying the barrier arm 3 and the swivel part 2, as well as compensating or resetting or closing springs 6 for the swivel part 2, which according to the exemplary embodiment in the closed position of the barrier Fig. 1 are excited and support the open position of the barrier, so they can keep open even when the motor fails.

Im vorliegenden Falle erfolgt der Antrieb von dem Antriebsmotor 4 aus über einen Schwenkarm 7, einen Zwischenarm 8 und einen Hebelarm 9, der seinerseits an der Abtriebswelle 5 drehfest angreift. Dabei sind der Schwenkarm 7, der Zwischenarm 8 und der Hebelarm 9 über Gelenke 10 in der in den Figuren 1 und 2 ersichtlichen Weise verbunden. An der Abtriebswelle 5 erkennt man ferner noch einen weiteren Hebelarm 11, welcher mit dieser Abtriebswelle 5 drehfest verbunden ist, und an den die Federn 6 angreifen, wobei dieser Hebelarm 11 nach der dem Hebelarm 9 entgegengesetzten Seite ragt und so die Federkraft der Antriebskraft entgegengesetzt wirksam machen kann.In the present case, the drive from the drive motor 4 takes place via a swivel arm 7, an intermediate arm 8 and a lever arm 9, which in turn acts on the output shaft 5 in a rotationally fixed manner. The swivel arm 7, the intermediate arm 8 and the lever arm 9 are connected via joints 10 in the manner shown in FIGS. 1 and 2. On the output shaft 5 you can also see another lever arm 11, which is rotatably connected to this output shaft 5 and to which the springs 6 engage, this lever arm 11 protruding toward the opposite side of the lever arm 9 and so the spring force of the driving force is effective in the opposite direction can make.

Vor allem in den Figuren 4 und 5 erkennt man, daß ein Träger für den Antriebsmotor 4, Träger für die Abtriebswelle 5 und ein Träger für das bzw. die festen Federenden 12 zu einem als Ganzes montierbaren Tragteil 13 verbunden sind, welches Tragteil 13 gemäß Fig. 5 noch zu beschreibende Befestigungsstellen 14 zum Anbringen der Antriebsvorrichtung 1 und des Tragteiles 13 an einem Schrankengehäuse 15 (Fig. 6) auf einem Pfosten 16 (Fig. 7) oder auch in einer Mauernische 17 (Fig. 8) hat. Daraus wird deutlich, daß dieses Tragteil 13 mit Motor, Abtriebswelle 5, Antriebs-Hebelsystem für die Abtriebswelle 5 und Federn 6 als ein Fertigteil vormontiert sein kann und vor allem sehr platzsparend gestaltet ist. Dies wird nicht zuletzt dadurch ermöglicht, daß die erforderliche Federkraft im Ausführungsbeispiel durch drei parallele kräftige Zugfedern (Fig. 4) erzeugt wird.Above all in FIGS. 4 and 5, it can be seen that a carrier for the drive motor 4, carrier for the output shaft 5 and a carrier for the fixed spring end (s) 12 are connected to a support part 13 which can be assembled as a whole, which support part 13 according to FIG 5 has to be described fastening points 14 for attaching the drive device 1 and the supporting part 13 to a barrier housing 15 (FIG. 6) on a post 16 (FIG. 7) or also in a wall recess 17 (FIG. 8). It is clear from this that this support part 13 with motor, output shaft 5, drive lever system for the output shaft 5 and springs 6 can be preassembled as a finished part and, above all, is designed to be very space-saving. This is made possible not least by the fact that the required spring force in the exemplary embodiment is generated by three parallel strong tension springs (FIG. 4).

Im einzelnen hat das Tragteil 13 eine Tragplatte 18 zum Anbringen des Antriebsmotors 4 ― gemäß Fig. 1 an der Unterseite der Tragplatte 18 ― sowie zwei beabstandete, zueinander parallele, rechtwinklig zu der Tragplatte 18 stehende und einander auf gleicher Höhe gegenüberliegende Flansche 19 zur Lagerung der Abtriebswelle 5. Gemäß Fig. 4 enthält das Tragteil 13 einen U-förmigen Querschnitt, wobei der Quersteg dieses U die Tragplatte 18 für den Motor 4 bildet und die beiden U-Schenkel die Flansche 19 für die Lagerung der Abtriebswelle 5 sind.Specifically, the support member 13 has a support plate 18 for attaching the drive motor 4 - according to FIG. 1 on the underside of the support plate 18 - as well as two spaced-apart, parallel, perpendicular to the support plate 18 and mutually opposite flanges 19 for storing the 4, the support member 13 has a U-shaped cross section, the crosspiece of this U forms the support plate 18 for the motor 4 and the two U-legs are the flanges 19 for the mounting of the output shaft 5.

Vor allem in Fig. 4 erkennt man außerdem, daß etwa in Fortsetzung der parallelen Flansche 19 jeweils Verlängerungen 20 vorgesehen sind, die gegenüber den Flanschen 19 nach der entgegengesetzen Seite der Halteplatte 18, im Ausführungsbeispiel auf der nach unten gerichteten Seite der Halteplatte 18, an welcher der Motor 4 angeordnet ist, überstehen. Diese Verlängerungen 20 tragen eine Halterung 21 für die festliegenden Federenden 12. Insgesamt ist also der Querschnitt des Tragteiles 13 durch diese Verlängerungen 20 zu einem H-förmigen Querschnitt ergänzt, wobei die gegenüber der Tragplatte 18 in Fig. 1 nach unten, also auf der Seite der Motoranbringung vorstehenden Stege dieses Querschnittes das Widerlager 21 für die Federenden 12 und einen Durchtritt 22 für das Antriebs-Hebelsystem des Antriebsmotors 4 aufweisen.Especially in Fig. 4 it can also be seen that extensions 20 are provided, for example, in continuation of the parallel flanges 19, which are opposite the flanges 19 to the opposite side of the holding plate 18, in the exemplary embodiment on the protrude downward side of the holding plate 18 on which the motor 4 is arranged. These extensions 20 carry a holder 21 for the fixed spring ends 12. Overall, the cross-section of the support member 13 is supplemented by these extensions 20 to an H-shaped cross-section, the opposite to the support plate 18 in Fig. 1 down, that is, on the side the motor attachment projecting webs of this cross-section have the abutment 21 for the spring ends 12 and a passage 22 for the drive lever system of the drive motor 4.

Aus den Figuren 1 bis 3 wird dabei deutlich, daß die Erstreckung der Tragplatte 18 quer zur Längserstreckung der Abtriebswelle 5 größer als die Breite zumindest der Verlängerungen 20 der von der Platte 18 abgehenden Flansche 19 ist, während die Flansche 19 selbst die gleiche Länge wie die Tragplatte 18 haben. Im Bereich des Überstandes 23 gegenüber den Verlängerungen 20 sind nun die schon erwähnten Befestigungstellen 14 zum Fixieren des Tragteiles 13 in einer beliebigen Montagestellung, von welcher drei Beispiele in den Figuren 6 bis 8 dargestellt sind, vorgesehen. Dabei erkennt man in Fig. 5, daß die Befestigungsstellen 14 an den beiden einander gegenüberliegenden, quer zu den seitlichen Flanschen 19 verlaufenden Rändern 24 der Tragplatte 18 vorgesehen und als Lochungen für Befestigungsschrauben, Bolzen od.dgl. ausgebildet sind. Wie in dieser Figur dargestellt, können dabei bereits vier derartige, als Lochungen ausgebildete Befestigungsstellen 14 ausreichen. Dies gilt vor allem dann, wenn in Montagestellung die Tragplatte 18 gemäß den Beispielen der Fig. 6 bis 8 etwa horizontal orientiert ist, so daß die diese Befestigungsstellen 14 durchsetzenden Befestigungsmittel vorwiegend nur Kräfte gegenüber seitlichen Verschiebungen auffangen müssen.From Figures 1 to 3 it is clear that the extension of the support plate 18 transverse to the longitudinal extension of the output shaft 5 is greater than the width of at least the extensions 20 of the flanges 19 extending from the plate 18, while the flanges 19 themselves have the same length as that Have support plate 18. In the area of the protrusion 23 with respect to the extensions 20, the fastening points 14 already mentioned are provided for fixing the supporting part 13 in any mounting position, three examples of which are shown in FIGS. 6 to 8. 5 that the fastening points 14 are provided on the two opposite edges 24 of the support plate 18 which run transversely to the side flanges 19 and as holes for fastening screws, bolts or the like. are trained. As shown in this figure, four such fastening points 14 designed as perforations can already suffice. This is especially true when the mounting plate 18 is approximately horizontal in the mounting position according to the examples in FIGS. 6 to 8 is oriented so that the fastening means penetrating these fastening points 14 predominantly only have to absorb forces with respect to lateral displacements.

In Fig. 4 und vor allem in Fig. 5 erkennt man, daß die Tragsplatte 18 seitlich der Motorbefestigung Durchbrüche 25 für die Rückstellefedern 6 hat und daß die Breite der Durchbrüche 25 zumindest etwa der Außenabmessung der Federn 6 entspricht bzw. diese Außenabmessung etwas übertrifft, während die Länge dieser Durchbrüche wenigstens dem Gesamt-Schwenkweg der Federn 6 bei der Schwenkbewegung des Schwenkteiles 2 von der einen in die andere Endstellung entspricht, was wegen der dadurch gleichzeitig bewirkten Verschwenkung des Hebelarmes 11 auch eine entsprechende Verschwenkung der Federn 6 um deren feste Halterung 21 bewirkt. Im Ausführungsbeispiel ist dabei eine der Anzahl der Federn entsprechende Zahl solcher Durchbrüche 25 vorgesehen, die als quer zur Abtriebswelle 5 orientierte Langlochungen ausgebildet sind.In Fig. 4 and especially in Fig. 5 it can be seen that the support plate 18 has openings 25 for the return springs 6 on the side of the motor mounting and that the width of the openings 25 corresponds at least approximately to the outer dimension of the springs 6 or slightly exceeds this outer dimension, while the length of these breakthroughs corresponds at least to the total pivoting path of the springs 6 during the pivoting movement of the pivoting part 2 from one end position to the other, which, because of the pivoting of the lever arm 11 caused thereby, also a corresponding pivoting of the springs 6 about their fixed mounting 21 causes. In the exemplary embodiment, a number of such openings 25 corresponding to the number of springs is provided, which are designed as oblong perforations oriented transversely to the output shaft 5.

Durch die vorbeschriebenen Merkmale und Maßnahmen kann die Tragplatte 18 des Tragteiles 13 mit ihren Überständen 23 in Gebrauchstellung brückenartig über eine etwa vertikale Ausnehmung od.dgl. eines Pfostens 16, eines Gehäuses 15 ― auch innerhalb eines Wandausschnittes 17 ― reichen. Der Motor 4 und die seitlich von ihm befindlichen, bei horizontaler Anordnung der Tragplatte 18 nach unten gerichteten Verlängerungen 20 sind dabei in diese Ausnehmung bzw. in ein solches Gehäuse 15 versenkt und die Flansche 19 mit der Abtriebswelle 5 und dem Schwenkteil 2 stehen demgegenüber vor. Für die Montage des Tragteiles 13 braucht dieses also ggfs. zusammen mit allen daran befindlichen Antriebsaggregaten nur von oben her in ein entsprechendes Gehäuse eingesetzt und an den Befestigungsstellen 14 fixiert zu werden.Due to the features and measures described above, the support plate 18 of the support member 13 with its projections 23 in the use position or the like in a bridge-like manner via an approximately vertical recess. a post 16, a housing 15 - also within a wall cutout 17 - range. The motor 4 and the extensions 20 located to the side of it, with the support plate 18 arranged horizontally downward, are sunk into this recess or into such a housing 15, and the flanges 19 with the output shaft 5 and the swivel part 2 are opposite. For the assembly of the supporting part 13, this may therefore need together with all of the parts thereon Drive units are only inserted from above into a corresponding housing and to be fixed at the fastening points 14.

Die die Abtriebswelle 5 haltenden Flansche 19 haben dabei im Ausführungsbeispiel eine etwa trapezförmige Kontur, wobei im Bereich der größten Höhe die Abtriebswelle 5 gelagert ist. Für von der Abtriebswelle 5 beaufschlagte Endschalter 26, Schalt-, Steuer- oder Fühlelemente kann nun in der in Figur 5 angedeuteten Weise zumindest eine Befestigungsstelle im Zwischenraum zwischen den Flanschen 19 angeordnet sein, der die in diesem Zwischenraum befindlichen Antriebsteile schützt.In the exemplary embodiment, the flanges 19 holding the output shaft 5 have an approximately trapezoidal contour, the output shaft 5 being mounted in the region of the greatest height. For limit switches 26, switching, control or sensing elements acted upon by the output shaft 5, at least one fastening point can now be arranged in the space indicated between the flanges 19 in the manner indicated in FIG. 5 and protects the drive parts located in this space.

In den Figuren 1 und 2 erkennt man noch, daß das Tragteil 13 in diesem Falle an einer der Verlängerungen 20 zwei Anschläge 27 für eine Festlegung beider Endlagen des schwenkbaren Teiles 2 aufweist, so daß bei Verwendung eines blockierbaren Motors 4 zumindest die eine dieser Endlagen unmittelbar von dem Motor 4 selbst und einem solchen Anschlag 27 festgelegt ist.In Figures 1 and 2 you can still see that the support member 13 has in this case on one of the extensions 20 two stops 27 for fixing both end positions of the pivotable part 2, so that when using a lockable motor 4 at least one of these end positions directly is determined by the motor 4 itself and such a stop 27.

Abschließend sei anhand der Fig. 3 noch erwähnt, daß einer der seitlich des Motors 4 angeordneten Stege 20, nämlich der auf der dem Motorabtrieb abgewandten Seite, der ausschließlich zur Abstützung des Widerlagers 21 für die festen Federenden 12 dient, nur eine stabförmige Strebe zu sein braucht. Dadurch kann weiteres Gewicht an der Vorrichtung 1 eingespart werden.Finally, it should be mentioned with reference to FIG. 3 that one of the webs 20 arranged on the side of the motor 4, namely that on the side facing away from the motor output, which serves only to support the abutment 21 for the fixed spring ends 12, is only a rod-like strut needs. This allows further weight to be saved on the device 1.

Eine bezüglich der Ausgleichs-, Rückstell- oder Schließfeder besonders platzsparende und kompakte Ausführungsform der Antriebsvorrichtung 1 ist in Fig. 9 in einer der Fig. 5 entsprechenden Ansicht dargestellt. Dabei erkennt man, daß eine Ausgleichs-, Rückstell- oder Schließfeder als über einen Teil der Länge der Abtriebswelle 5 reichende Wickelfeder 28 ausgebildet ist, deren schraubenförmige Winderungen 28a mit radialem Abstand oder Spiel um die Abtriebswelle 5 verlaufen. Somit nimmt diese Feder 28 paktrisch keinen zusätzlichen Raum ein. Insbesondere bedarf es bei einer solchen Ausführungsform keiner Flanschverlängerungen oder Stege 20, um Zugfedern mit ihrem festen Federende 12 zu verankern.An especially space-saving and compact embodiment of the drive device 1 with respect to the compensating, returning or closing spring is shown in FIG. 9 in a view corresponding to FIG. 5. It can be seen that a compensating, return or closing spring is designed as a coil spring 28 extending over part of the length of the output shaft 5, the helical curvatures 28a of which extend around the output shaft 5 with radial clearance or play. Thus, this spring 28 does not take up any additional space. In particular, such an embodiment does not require any flange extensions or webs 20 in order to anchor tension springs with their fixed spring end 12.

Besonders zweckmäßig ist es dabei, wenn gemäß Fig. 9 die Wickelfeder 28 die einzige Feder ist. Dabei kann ein Ende 28b gemäß Fig. 9 an dem in diesem Falle motorfernen Flansch 19 und das andere Ende 28c an einem gegenüber der Abtriebswelle 5 radial vorstehenden Vorsprung oder Bund 29 angreifen, um das beim Spannen der Feder entstehende Drehmoment zu übertragen. Dabei wird die Wicklung der Feder 28 bei ihrem Spannen durch die dabei erfolgende Drehung der Abtriebswelle 5 enger, so daß die gewünschten Rückstellkräfte an dieser Feder 28 entstehen.It is particularly useful if the winding spring 28 is the only spring according to FIG. 9. In this case, one end 28b according to FIG. 9 can engage on the flange 19 remote from the motor in this case and the other end 28c on a projection or collar 29 which projects radially with respect to the output shaft 5 in order to transmit the torque which arises when the spring is tensioned. The winding of the spring 28 becomes tighter as it is tensioned by the rotation of the output shaft 5, so that the desired restoring forces are generated on this spring 28.
