Definitions
- the invention relates to a roller shutter box, with a box body and at least one front box lid, and with at least one electric drive with associated gear for a roller shutter curtain.
- the box body consists of three covers and a bottom cover.
- the cover plates are a front cover, a head cover and a rear cover.
- the roller shutter curtain is regularly arranged in the body of the box.
- a fly screen can of course also be provided.
- the aforementioned electric drive can in principle also be used to operate this fly screen. Of course, a separate (electric) drive can also be provided for this.
- a roller shutter box of the configuration described in the introduction has become known from DE-C 196 10 432. Embodiments of this type cannot fundamentally convince because the electric drive in question with a gear mechanism has a protruding structure and is hardly accessible for installation or inspection purposes.
- EP 0 430 834 A1 shows a roller shutter box which has an actuating device on the end. This is attached to its own intermediate flange, which also serves to mount the roller shutter curtain, the electrical drive including gear having a height adapted to the space remaining between the roller shutter curtain and the case cover or its inside of the case cover.
- the invention is based on the technical problem of developing such a roller shutter box in such a way that a compact drive for the roller shutter curtain can be implemented in conjunction with simple installation and removal.
- the invention proposes - starting from a roller shutter box of the type described above - that electric drive and the gearbox together with the box cover form a pre-assembled unit.
- the electric drive including the gearbox can largely be arranged or housed in the (box) interior of the box lid, that is, if you like, within the depth of this box lid.
- the electric drive and the transmission can also be designed as exchange modules for adapting to different box bodies and / or roller shutter curtains.
- a preferably watertight, in particular fast-running, alternating current motor is generally used as the electrical drive.
- the electric drive can extend parallel to the relevant inner side / inside of the box lid or box lid base plane.
- the gear unit is preferably designed as a reduction gear unit.
- it is usually essentially composed of a worm gear stage that interacts with the armored shaft and a gear or toothed belt gear stage.
- the worm gear stage In order to achieve total freedom from maintenance, the worm gear stage generally forms, together with a journal receptacle for the armored shaft, an encapsulated structural unit with an input shaft connected to the gear or belt transmission stage.
- the gearwheels of the gearwheel or toothed belt gear stage In order to implement a power transmission with as little loss as possible, the gearwheels of the gearwheel or toothed belt gear stage generally rotate in a gearwheel gear plane which is coplanar compared to the plane of rotation of the output shaft of the electric drive. Since this gear transmission plane is almost always arranged perpendicular to the armored shaft rotation plane, a corresponding conversion of the rotational movements must take place.
- the worm gear stage is used for this purpose, which converts rotations of the gears in the gear transmission plane into rotary movements of the armored shaft in the armored shaft rotation plane perpendicular thereto.
- the armored shaft rotation plane can preferably coincide with the box cover base plane or can be aligned parallel to this.
- both of the above-mentioned components are arranged in the inside of the box of the box lid, and are usually inserted on the inside of this box lid by means of screws or snap-in connections. Due to the fact that the overall height of both of the above-mentioned parts is adapted to the space remaining between the roller shutter curtain and box cover or its box cover base plane, modifications of the roller shutter box according to the invention are limited to a minimum in comparison with a purely manual actuation of the roller shutter curtain. Because these usually only refer to the replacement of the box lid. Due to the limited overall height of one hand electric drive, on the other hand associated gearbox, there is no fear of impairment of the functioning of the roller shutter curtain.
- the invention allows the compact design of an electric drive including gear, which together with the box cover form a preassembled structural unit, which is optionally attached to the end of a box body at the end.
- a roller shutter box can be adapted to electrical or manual actuation of the roller shutter curtain simply by exchanging the box cover accordingly.
- a roller shutter box which is equipped with a box body K and two front box covers 1, 2.
- the box body K is made in a known manner from cover 3 and a bottom cover 4, which are designed as hollow plastic profiles.
- any other designs of the box body K are also conceivable.
- the electric drive 5 including gear 6 is in the Box interior of a box lid 1 arranged.
- the remaining front box cover 2, on the other hand, is of conventional design, that is to say carries only one pin receptacle 8 for an armored shaft 9 of the roller shutter armor 7.
- This pin receptacle 8 has an internal toothing in which the armored shaft 9 engages non-rotatably with correspondingly toothed shaft journal ends (see FIG. 2 ).
- the electric drive 5 and the gear 6 are designed as exchange modules, so that an adaptation to different box bodies K and / or roller shutter armor 7 is made possible.
- different widths of the roller shutter curtain 7 (and thus also weights) and possibly different materials of the associated roller shutter slats (plastic or aluminum, which also influence the weight) can be taken into account , The same applies with regard to the length of the box body K.
- the electric drive 5 including the gear 6 has a certain overall height H.
- This height H is adapted to an intermediate space Z which remains between the roller shutter armor 7 and the box cover 1 or its box cover base plane KGE.
- This measure enables the box cover modified in this way to be exchanged for a conventional box cover 2 without adjustments to the roller shutter curtain 7 and / or box body K having to be made.
- the inside of the modified Box cover 1 corresponding recesses for receiving the electric drive 5 together with gear 6 are provided. These can be snap-in receptacles in which the two aforementioned components 5, 6 are snapped into place. Usually, an additional screw connection is carried out on the box cover 1.
- the electric drive 5 is a watertight, according to the exemplary embodiment, high-speed AC motor 5, which is operated with the usual AC voltage.
- an interference suppression capacitor is arranged in the area of the box cover, for which a receptacle is also provided.
- a corresponding design of the box cover 1 is easily possible because, according to the exemplary embodiment, this is an injection molded plastic part.
- the electric drive 5 or AC motor 5 extends longitudinally parallel to the box cover base plane KGE. Because this AC motor or electric drive 5 reaches relatively high speeds, the associated gear 6 is designed as a reduction gear. This is because the roller shutter curtain 7 acted upon by the gear 6 only has to make a few revolutions (slowly). For the rest, this makes it possible to use a compact and small-sized motor with not too high performance, which is consequently inexpensive.
- the transmission 6 shown is composed essentially of two stages, namely a worm gear stage 6a interacting with the armored shaft 7 and a gear stage 6b. Instead of this gear transmission stage 6b, a toothed belt gear stage can also be used, but this is not shown.
- the worm gear stage 6a forms together with the pin receptacle 8 on the box cover 1 an encapsulated structural unit. From this encapsulated unit, only an input shaft 10 leads to the gear transmission stage 6b.
- the individual gearwheels of gear transmission stage 6b identified by reference numeral 11, all rotate in a gearwheel gear plane ZGE.
- This gear transmission plane ZGE is arranged perpendicular to the armored shaft rotation plane PRE, which is described by the rotations of the armored shaft 7 and coincides with the drawing plane in FIG. 2 and the box cover base plane KGE.
- the gear wheels 11 of the gear transmission stage 6b rotate in a gear transmission plane ZGE that is coplanar compared to the rotation plane R of an output shaft 12 of the electric drive 5.
- the output shaft 12 of the electric drive 5 also has a toothing which meshes with a connected gear 11.
- the ratio of the number of teeth of the output shaft 12 compared to the number of teeth of the gear 11 meshing therewith essentially determines the reduction ratio.
- a bevel gear stage can also be used.
- the worm gear stage 6a converts the rotations of the gearwheels 11 in the gearwheel gear plane ZGE into rotary movements of the armored shaft 7 in the armored shaft rotation plane PRE perpendicular thereto.
- remote control of the functions of the roller shutter curtain 7 is of course also possible.
- a corresponding receiver 13 is arranged in the box body K, which is operated via a transmission device 14, also shown.
- a timer can also be implemented.

Abstract
Description
Die Erfindung betrifft einen Rollladenkasten, mit einem Kastenkörper und zumindest einem stirnseitigen Kastendeckel, und mit wenigstens einem elektrischen Antrieb mit zugehörigem Getriebe für einen Rollladenpanzer. - Üblicherweise besteht der Kastenkörper aus drei Blenddeckeln und einem Bodendeckel. Bei den Blenddeckeln handelt es sich um einen frontseitigen, einen kopfseitigen und einen rückseitigen Blenddeckel. Der Rollladenpanzer ist regelmäßig im Kastenkörper angeordnet. Neben dem vorgenannten Rollladenpanzer kann selbstverständlich zusätzlich ein Fliegengitter vorgesehen sein. Der vorgenannte elektrische Antrieb lässt sich grundsätzlich auch zur Betätigung dieses Fliegengitters verwenden. Selbstverständlich kann hierfür auch ein eigener (elektrischer) Antrieb vorgesehen werden.The invention relates to a roller shutter box, with a box body and at least one front box lid, and with at least one electric drive with associated gear for a roller shutter curtain. - Usually, the box body consists of three covers and a bottom cover. The cover plates are a front cover, a head cover and a rear cover. The roller shutter curtain is regularly arranged in the body of the box. In addition to the aforementioned roller shutter curtain, a fly screen can of course also be provided. The aforementioned electric drive can in principle also be used to operate this fly screen. Of course, a separate (electric) drive can also be provided for this.
Ein Rollladenkasten der eingangs beschriebenen Ausgestaltung ist durch die DE-C 196 10 432 bekannt geworden. Derartige Ausführungsformen können nicht grundsätzlich überzeugen, weil der betreffende elektrische Antrieb mit Getriebe ausladend aufgebaut und für Einbau- oder Revisionszwecke kaum zugänglich ist.A roller shutter box of the configuration described in the introduction has become known from DE-C 196 10 432. Embodiments of this type cannot fundamentally convince because the electric drive in question with a gear mechanism has a protruding structure and is hardly accessible for installation or inspection purposes.
Durch die DE 39 20 656 A1 ist ein Rollladensystem mit zwischen die Leibung einer Mauerwerksöffnung einfügbarem Rollladenkasten bekannt geworden. Hier wird so vorgegangen, dass ein zugehöriger Rollladenantrieb unter Verwendung eines an der Rollladenwelle anzusetzenden Versetzungsgetriebes aus der vorerwähnten Mauerwerksöffnung heraus verlagert wird. Auf diese Weise erhofft man sich, auf Stemmarbeiten in der antriebsseitigen Leibung der Mauerwerksöffnung verzichten zu können. Das wird jedoch mit einem kompliziertem Rollladenantrieb mit additivem Versetzungsgetriebe erkauft.DE 39 20 656 A1 discloses a roller shutter system with a roller shutter box that can be inserted between the reveal of a masonry opening. Here, the procedure is such that an associated roller shutter drive, using a displacement gear to be attached to the roller shutter shaft, emerges from the aforementioned masonry opening is shifted. In this way, one hopes to be able to do without chiselling work in the drive-side reveal of the masonry opening. However, this is bought with a complicated roller shutter drive with an additive offset gear.
Die DE 37 39 465 C1 beschäftigt sich mit einer Vorrichtung zum Antrieb einer Schwimmbadabdeckung. Zu diesem Zweck ist ein Gehäuse vorgesehen, welches in seinem Inneren alle kompakt hierin untergebrachten Vorrichtungsteile regensicher schützt. Die vorerwähnten Probleme sind durch diese Vorveröffentlichung nicht maßgeblich beeinflusst worden.DE 37 39 465 C1 deals with a device for driving a swimming pool cover. For this purpose, a housing is provided which protects all parts of the device accommodated therein in a rainproof manner inside. The aforementioned problems have not been significantly influenced by this prior publication.
Schließlich zeigt die EP 0 430 834 A1 einen Rollladenkasten, welcher über eine stirnseitige Betätigungsvorrichtung verfügt. Diese ist an einem eigenen Zwischenflansch angebracht, welcher gleichzeitig zur Lagerung des Rollladenpanzers dient, wobei der elektrische Antrieb inklusive Getriebe eine an den zwischen Rollladenpanzer und Kastendeckel bzw. dessen Kastendeckelinnenseite verbleibenden Zwischenraum angepasste Bauhöhe aufweist.Finally, EP 0 430 834 A1 shows a roller shutter box which has an actuating device on the end. This is attached to its own intermediate flange, which also serves to mount the roller shutter curtain, the electrical drive including gear having a height adapted to the space remaining between the roller shutter curtain and the case cover or its inside of the case cover.
Der Erfindung liegt das technische Problem zugrunde, einen derartigen Rollladenkasten so weiterzubilden, dass sich ein kompakter Antrieb des Rollladenpanzers in Verbindung mit einem einfachen Ein- und Ausbau realisieren lässt.The invention is based on the technical problem of developing such a roller shutter box in such a way that a compact drive for the roller shutter curtain can be implemented in conjunction with simple installation and removal.
Zur Lösung dieser Aufgabe schlägt die Erfindung - ausgehend von einem Rollladenkasten der eingangs beschriebenen Gattung - vor, dass der elektrische Antrieb und das Getriebe zusammen mit dem Kastendeckel eine vormontierte Baueinheit bilden.To solve this problem, the invention proposes - starting from a roller shutter box of the type described above - that electric drive and the gearbox together with the box cover form a pre-assembled unit.
Hierdurch kann der elektrische Antrieb inklusive Getriebe größtenteils im (Kasten-)Innenbereich des Kastendeckels, also wenn man so will innerhalb der Tiefe dieses Kastendeckels, angeordnet bzw. untergebracht werden. Nach bevorzugter Ausgestaltung können darüber hinaus der elektrische Antrieb und das Getriebe als Austauschmodule zur Anpassung an unterschiedliche Kastenkörper und/oder Rollladenpanzer ausgeführt sein.As a result, the electric drive including the gearbox can largely be arranged or housed in the (box) interior of the box lid, that is, if you like, within the depth of this box lid. According to a preferred embodiment, the electric drive and the transmission can also be designed as exchange modules for adapting to different box bodies and / or roller shutter curtains.
Ferner kommt in der Regel als elektrischer Antrieb ein vorzugsweise wasserdichter, insbesondere schnelllaufender, Wechselstrommotor zum Einsatz. Dabei kann sich der elektrische Antrieb parallel zur betreffenden Innenseite/Kastendeckelinnenseite bzw. Kastendeckelgrundebene längs erstrecken.Furthermore, a preferably watertight, in particular fast-running, alternating current motor is generally used as the electrical drive. The electric drive can extend parallel to the relevant inner side / inside of the box lid or box lid base plane.
Weil der elektrische Antrieb schnelllaufend ist und der Rollladenpanzer bzw. dessen zugehörige Panzerwelle nur wenige Umdrehungen vollführen muss, ist das Getriebe vorzugsweise als Untersetzungsgetriebe ausgeführt. Zu diesem Zweck ist es üblicherweise im Wesentlichen aus einer mit der Panzerwelle zusammenwirkenden Schneckenradgetriebestufe und einer Zahnrad- oder Zahnriemengetriebestufe zusammengesetzt. Um insgesamt Wartungsfreiheit zu erreichen, bildet die Schneckenradgetriebestufe im Allgemeinen zusammen mit einer Zapfenaufnahme für die Panzerwelle eine gekapselte Baueinheit mit an die Zahnrad- bzw. Zahnriemengetriebestufe angeschlossener Eingangswelle.Because the electric drive runs fast and the roller shutter curtain or its associated armored shaft only has to make a few revolutions, the gear unit is preferably designed as a reduction gear unit. For this purpose, it is usually essentially composed of a worm gear stage that interacts with the armored shaft and a gear or toothed belt gear stage. In order to achieve total freedom from maintenance, the worm gear stage generally forms, together with a journal receptacle for the armored shaft, an encapsulated structural unit with an input shaft connected to the gear or belt transmission stage.
Um eine möglichst verlustarme Kraftübertragung zu realisieren, rotieren die Zahnräder der Zahnrad- oder Zahnriemengetriebestufe in der Regel in einer im Vergleich zur Rotationsebene der Ausgangswelle des elektrischen Antriebes koplanaren Zahnradgetriebeebene. Da diese Zahnradgetriebeebene fast immer senkrecht zur Panzerwellenrotationsebene angeordnet ist, muss eine entsprechende Umwandlung der Rotationsbewegungen stattfinden. Hierzu dient nach bevorzugter Ausgestaltung die Schneckenradgetriebestufe, welche Rotationen der Zahnräder in der Zahnradgetriebeebene in Drehbewegungen der Panzerwelle in der hierzu senkrechten Panzerwellenrotationsebene umwandelt. Dabei kann die Panzerwellenrotationsebene vorzugsweise mit der Kastendeckelgrundebene zusammenfallen oder hierzu parallel ausgerichtet sein.In order to implement a power transmission with as little loss as possible, the gearwheels of the gearwheel or toothed belt gear stage generally rotate in a gearwheel gear plane which is coplanar compared to the plane of rotation of the output shaft of the electric drive. Since this gear transmission plane is almost always arranged perpendicular to the armored shaft rotation plane, a corresponding conversion of the rotational movements must take place. According to a preferred embodiment, the worm gear stage is used for this purpose, which converts rotations of the gears in the gear transmission plane into rotary movements of the armored shaft in the armored shaft rotation plane perpendicular thereto. The armored shaft rotation plane can preferably coincide with the box cover base plane or can be aligned parallel to this.
Im Ergebnis wird zunächst einmal ein kompakter Aufbau des elektrischen Antriebes inklusive Getriebe dadurch erreicht, dass beide vorgenannten Bauelemente im Kasteninnenbereich des Kastendeckels angeordnet sind, und zwar üblicherweise mittels Schrauben oder Rastverbindungen in diesen Kastendeckel innenseitig eingesetzt werden. Dadurch, dass die Bauhöhe beider vorgenannten Teile an den zwischen Rollladenpanzer und Kastendeckel bzw. dessen Kastendeckelgrundebene verbleibenden Zwischenraum angepasst ist, sind Modifikationen des erfindungsgemäßen Rollladenkastens im Vergleich zu einem mit rein manueller Betätigung des Rollladenpanzers auf ein Minimum beschränkt. Denn diese beziehen sich üblicherweise lediglich auf den Austausch des Kastendeckels. Durch die begrenzte Bauhöhe von einerseits elektrischem Antrieb, andererseits zugehörigem Getriebe sind Beeinträchtigungen der Funktionsweise des Rollladenpanzers nicht zu befürchten.As a result, a compact construction of the electric drive including the gearbox is first achieved in that both of the above-mentioned components are arranged in the inside of the box of the box lid, and are usually inserted on the inside of this box lid by means of screws or snap-in connections. Due to the fact that the overall height of both of the above-mentioned parts is adapted to the space remaining between the roller shutter curtain and box cover or its box cover base plane, modifications of the roller shutter box according to the invention are limited to a minimum in comparison with a purely manual actuation of the roller shutter curtain. Because these usually only refer to the replacement of the box lid. Due to the limited overall height of one hand electric drive, on the other hand associated gearbox, there is no fear of impairment of the functioning of the roller shutter curtain.
Dies alles gelingt im Kern dadurch, dass als elektrischer Antrieb auf einen vorzugsweise schnellaufenden Wechselstrommotor zurückgegriffen wird, dessen hohe Drehzahlen mit Hilfe des untersetzend ausgeführten Getriebes in entsprechende Drehbewegungen der Panzerwelle des Rollladenpanzers umgewandelt werden. Dies wird darüber hinaus verlustarm und praktisch wartungsfrei dadurch erreicht, dass das Getriebe seinerseits aus zwei Stufen zusammengesetzt ist,. nämlich einer Zahnrad- bzw. Zahnriemengetriebestufe und einer Schneckenradgetriebestufe. Selbstverständlich kann anstelle der Zahnriemengetriebestufe auch eine solche Getriebestufe verwirklicht sein, die zur Übersetzung statt Zahnriemen auf Ketten abstellt. Da jedoch Zahnriemen wartungsfrei sind, kommt üblicherweise eine Zahnriemengetriebestufe oder eben eine Zahnradgetriebestufe zum Einsatz.In essence, all of this is achieved by using a preferably high-speed AC motor as the electric drive, the high speeds of which are converted into corresponding rotary movements of the armored shaft of the roller shutter curtain with the help of the reduction gear. In addition, this is achieved with little loss and practically maintenance-free because the gearbox itself is composed of two stages. namely a gear or toothed belt gear stage and a worm gear stage. Of course, instead of the toothed belt gear stage, such a gear stage can also be implemented, which is geared to chains instead of toothed belts. However, since toothed belts are maintenance-free, a toothed belt gear stage or a gear wheel stage is usually used.
Endlich lassen sich mit Hilfe der Schneckenradgetriebestufe Rotationen der Zahnräder in der Zahnradgetriebeebene in hierzu senkrecht vollführte Drehbewegungen der Panzerwelle umwandeln. Dies geschieht gleichsam automatisch und verlustarm, weil ein Schneckenradgetriebe für eine derartige Umwandlung von Rotationsbewegungen geradezu prädestiniert ist. Selbstverständlich könnte an dieser Stelle auch eine Kegelradgetriebestufe zum Einsatz kommen. - Jedenfalls erlaubt die Erfindung die kompakte Ausgestaltung eines elektrischen Antriebes inklusive Getriebe, welche zusammen mit dem Kastendeckel eine vormontierte Baueinheit bilden, die optional stirnseitig an einen Kastenkörper zu dessen Abschluss angesetzt wird. Folglich gelingt eine Anpassung eines Rollladenkastens an elektrische oder manuelle Betätigung des Rollladenpanzers einfach durch entsprechenden Austausch des Kastendeckels.Finally, with the help of the worm gear stage, rotations of the gearwheels in the gearwheel gear plane can be converted into rotational movements of the armored shaft that are carried out vertically. This happens, as it were, automatically and with little loss, because a worm gear is predestined for such a conversion of rotational movements. Of course, a bevel gear stage could also be used at this point. In any case, the invention allows the compact design of an electric drive including gear, which together with the box cover form a preassembled structural unit, which is optionally attached to the end of a box body at the end. As a result, a roller shutter box can be adapted to electrical or manual actuation of the roller shutter curtain simply by exchanging the box cover accordingly.
Im Rahmen der Erfindung liegen selbstverständlich auch Ausgestaltungen derart, dass zwei Kastendeckel an gegenüberliegenden Stirnseiten des Kastenkörpers mit entsprechenden elektrischen Antrieben und zugehörigen Getrieben ausgerüstet sind. Dies ist jedoch aus Kostengründen nicht der Normalfall. Darüber hinaus ermöglicht die Erfindung selbstverständlich sowohl eine manuelle als auch eine fernbedienbare (elektrische) Betätigung des Rollladenpanzers.Within the scope of the invention there are of course also configurations such that two box covers on opposite end faces of the box body with corresponding electric drives and associated gearboxes. However, this is not the norm for cost reasons. In addition, of course, the invention enables both manual and remote-controlled (electrical) actuation of the roller shutter curtain.
Im Folgenden wird die Erfindung anhand lediglich ein Ausführungsbeispiel darstellenden Zeichnung näher erläutert; es zeigen:

- a view of the object of FIG. 2 from the direction X.
In den Figuren ist ein Rollladenkasten dargestellt, der mit einem Kastenkörper K sowie zwei stirnseitigen Kastendeckeln 1, 2 ausgerüstet ist. Der Kastenkörper K besteht in bekannter Weise aus Blenddeckeln 3 sowie einem Bodendeckel 4, die als Kunststoffhohlprofile ausgebildet sind. Selbstverständlich sind auch jedwede andere Ausführungen des Kastenkörpers K denkbar. Darüber hinaus findet sich ein elektrischer Antrieb 5 mit Getriebe 6 für einen innerhalb des Kastenkörpers K angeordneten Rollladenpanzer 7. Der elektrische Antrieb 5 inklusive Getriebe 6 ist im Kasteninnenbereich des einen Kastendeckels 1 angeordnet. Der verbleibende stirnseitige Kastendeckel 2 ist demgegenüber konventionell ausgeführt, d. h. trägt lediglich eine Zapfenaufnahme 8 für eine Panzerwelle 9 des Rollladenpanzers 7. Diese Zapfenaufnahme 8 weist eine innenseitige Verzahnung auf, in welche die Panzerwelle 9 mit entsprechend gezahnten Wellenzapfenenden unverdrehbar eingreift (vgl. Fig. 2).In the figures, a roller shutter box is shown, which is equipped with a box body K and two front box covers 1, 2. The box body K is made in a known manner from cover 3 and a bottom cover 4, which are designed as hollow plastic profiles. Of course, any other designs of the box body K are also conceivable. In addition, there is an electric drive 5 with gear 6 for a roller shutter curtain 7 arranged inside the box body K. The electric drive 5 including gear 6 is in the Box interior of a box lid 1 arranged. The remaining front box cover 2, on the other hand, is of conventional design, that is to say carries only one pin receptacle 8 for an armored shaft 9 of the roller shutter armor 7. This pin receptacle 8 has an internal toothing in which the armored shaft 9 engages non-rotatably with correspondingly toothed shaft journal ends (see FIG. 2 ).
Der elektrische Antrieb 5 und das Getriebe 6 sind als Austauschmodule ausgeführt, so dass eine Anpassung an unterschiedliche Kastenkörper K und/oder Rollladenpanzer 7 ermöglicht wird. Mit anderen Worten kann durch entsprechende Auswahl des Antriebes 5 sowie ggf. des Getriebes 6 unterschiedlichen Breiten des Rollladenpanzers 7 (und damit auch Gewichten) sowie ggf. verschiedenen Materialien der zugehörigen Rollladenstäbe (Kunststoff bzw. Aluminium, die ebenfalls das Gewicht beeinflussen) Rechnung getragen werden. Vergleichbares gilt mit Blick auf die Länge des Kastenkörpers K.The electric drive 5 and the gear 6 are designed as exchange modules, so that an adaptation to different box bodies K and / or roller shutter armor 7 is made possible. In other words, by appropriate selection of the drive 5 and possibly the gear 6 different widths of the roller shutter curtain 7 (and thus also weights) and possibly different materials of the associated roller shutter slats (plastic or aluminum, which also influence the weight) can be taken into account , The same applies with regard to the length of the box body K.
Anhand der Fig. 2 und 3 erkennt man, dass der elektrische Antrieb 5 inklusive Getriebe 6 eine bestimmte Bauhöhe H aufweist. Diese Bauhöhe H ist an einen Zwischenraum Z angepasst, welcher zwischen Rollladenpanzer 7 und Kastendeckel 1 bzw. dessen Kastendeckelgrundebene KGE verbleibt. Durch diese Maßnahme gelingt es, den so modifizierten Kastendeckel gegen einen konventionellen Kastendeckel 2 austauschen zu können, ohne dass Anpassungen am Rollladenpanzer 7 und/oder Kastenkörper K vorgenommen werden müssen. - Selbstverständlich sind innenseitig des modifizierten Kastendeckels 1 entsprechende Aussparungen zur Aufnahme des elektrischen Antriebes 5 nebst Getriebe 6 vorgesehen. Hierbei kann es sich um Rastaufnahmen handeln, in welche die beiden vorgenannten Bauteile 5, 6 eingerastet werden. Üblicherweise erfolgt flankierend eine zusätzliche Verschraubung am Kastendeckel 1.2 and 3 it can be seen that the electric drive 5 including the gear 6 has a certain overall height H. This height H is adapted to an intermediate space Z which remains between the roller shutter armor 7 and the box cover 1 or its box cover base plane KGE. This measure enables the box cover modified in this way to be exchanged for a conventional box cover 2 without adjustments to the roller shutter curtain 7 and / or box body K having to be made. - Of course, the inside of the modified Box cover 1 corresponding recesses for receiving the electric drive 5 together with gear 6 are provided. These can be snap-in receptacles in which the two aforementioned components 5, 6 are snapped into place. Usually, an additional screw connection is carried out on the box cover 1.
Bei dem elektrischen Antrieb 5 handelt es sich um einen wasserdichten, nach dem Ausführungsbeispiel schnellaufenden Wechselstrommotor 5, welcher mit üblicher Wechselspannung betrieben wird. In der Regel ist im Bereich des Kastendeckels auch ein Entstörkondensator angeordnet, für welchen ebenfalls eine Aufnahme vorgesehen ist. Eine entsprechende Ausgestaltung des Kastendeckels 1 ist unschwer möglich, weil es sich nach dem Ausführungsbeispiel hierbei um ein gespritztes Kunststoffformteil handelt.The electric drive 5 is a watertight, according to the exemplary embodiment, high-speed AC motor 5, which is operated with the usual AC voltage. As a rule, an interference suppression capacitor is arranged in the area of the box cover, for which a receptacle is also provided. A corresponding design of the box cover 1 is easily possible because, according to the exemplary embodiment, this is an injection molded plastic part.
Anhand der Fig. 2 und 3 erkennt man, dass sich der elektrische Antrieb 5 bzw. Wechselstrommotor 5 parallel zur Kastendeckelgrundebene KGE längserstreckt. Weil dieser Wechselstrommotor bzw. elektrischer Antrieb 5 relativ hohe Drehzahlen erreicht, ist das zugehörige Getriebe 6 als Untersetzungsgetriebe ausgeführt. Denn der von dem Getriebe 6 beaufschlagte Rollladenpanzer 7 muss lediglich wenige Umdrehungen (langsam) ausführen. Im übrigen kann hierdurch auf einen kompakten und kleinbauenden Motor mit nicht allzu hoher Leistung zurückgegriffen werden, der folglich preiswert ist. Das dargestellte Getriebe 6 setzt sich im Wesentlichen aus zwei Stufen zusammen, nämlich einer mit der Panzerwelle 7 zusammenwirkenden Schneckenradgetriebestufe 6a und einer Zahnradgetriebestufe 6b. Anstelle dieser Zahnradgetriebestufe 6b kann auch eine Zahnriemengetriebestufe zum Einsatz kommen, die jedoch nicht dargestellt ist. Die Schneckenradgetriebestufe 6a bildet zusammen mit der Zapfenaufnahme 8 am Kastendeckel 1 eine gekapselte Baueinheit. Aus dieser gekapselten Baueinheit führt lediglich eine Eingangswelle 10 zur Zahnradgetriebestufe 6b. Die einzelnen, mit dem Bezugszeichen 11 gekennzeichneten, Zahnräder der Zahnradgetriebestufe 6b rotieren sämtlich in einer Zahnradgetriebeebene ZGE. Diese Zahnradgetriebeebene ZGE ist senkrecht zur Panzerwellenrotationsebene PRE angeordnet, welche durch die Rotationen der Panzerwelle 7 beschrieben wird und mit der Zeichenblattebene in Fig. 2 sowie der Kastendeckelgrundebene KGE zusammenfällt.2 and 3 it can be seen that the electric drive 5 or AC motor 5 extends longitudinally parallel to the box cover base plane KGE. Because this AC motor or electric drive 5 reaches relatively high speeds, the associated gear 6 is designed as a reduction gear. This is because the roller shutter curtain 7 acted upon by the gear 6 only has to make a few revolutions (slowly). For the rest, this makes it possible to use a compact and small-sized motor with not too high performance, which is consequently inexpensive. The transmission 6 shown is composed essentially of two stages, namely a worm gear stage 6a interacting with the armored shaft 7 and a gear stage 6b. Instead of this gear transmission stage 6b, a toothed belt gear stage can also be used, but this is not shown. The worm gear stage 6a forms together with the pin receptacle 8 on the box cover 1 an encapsulated structural unit. From this encapsulated unit, only an input shaft 10 leads to the gear transmission stage 6b. The individual gearwheels of gear transmission stage 6b, identified by reference numeral 11, all rotate in a gearwheel gear plane ZGE. This gear transmission plane ZGE is arranged perpendicular to the armored shaft rotation plane PRE, which is described by the rotations of the armored shaft 7 and coincides with the drawing plane in FIG. 2 and the box cover base plane KGE.
Die Zahnräder 11 der Zahnradgetriebestufe 6b rotieren in einer im Vergleich zur Rotationsebene R einer Ausgangswelle 12 des elektrischen Antriebes 5 koplanaren Zahnradgetriebeebene ZGE. Nach dem Ausführungsbeispiel weist die Ausgangswelle 12 des elektrischen Antriebes 5 ebenfalls eine Verzahnung auf, die mit einem angeschlossenen Zahnrad 11 kämmt. Das Verhältnis der Zähnezahl der Ausgangswelle 12 im Vergleich zur Zähnezahl des hiermit kämmenden Zahnrades 11 bestimmt im wesentlichen das Untersetzungsverhältnis.The gear wheels 11 of the gear transmission stage 6b rotate in a gear transmission plane ZGE that is coplanar compared to the rotation plane R of an output shaft 12 of the electric drive 5. According to the embodiment, the output shaft 12 of the electric drive 5 also has a toothing which meshes with a connected gear 11. The ratio of the number of teeth of the output shaft 12 compared to the number of teeth of the gear 11 meshing therewith essentially determines the reduction ratio.
Anstelle der Schneckenradgetriebestufe 6a kann auch eine nicht dargestellte Kegelradgetriebestufe zum Einsatz kommen. Die Schneckenradgetriebestufe 6a wandelt die Rotationen der Zahnräder 11 in der Zahnradgetriebeebene ZGE in Drehbewegungen der Panzerwelle 7 in der hierzu senkrechten Panzerwellenrotationsebene PRE um. Neben einer manuellen Betätigung des elektrischen Antriebes 5 inklusive des Getriebes 6 mit Hilfe eines Schalters ist selbstverständlich auch eine Fernbedienung der Funktionen des Rollladenpanzers 7 möglich. Zu diesem Zweck ist im Kastenkörper K ein entsprechender Empfänger 13 angeordnet, welcher über eine ebenfalls dargestellte Sendevorrichtung 14 bedient wird. Auch eine Zeitschaltung kann realisiert werden.Instead of the worm gear stage 6a, a bevel gear stage, not shown, can also be used. The worm gear stage 6a converts the rotations of the gearwheels 11 in the gearwheel gear plane ZGE into rotary movements of the armored shaft 7 in the armored shaft rotation plane PRE perpendicular thereto. In addition to manual actuation of the electric drive 5 including the gear 6 with the aid of a switch, remote control of the functions of the roller shutter curtain 7 is of course also possible. For this purpose, a corresponding receiver 13 is arranged in the box body K, which is operated via a transmission device 14, also shown. A timer can also be implemented.
