Description

Zunächst betrifft die Erfindung eine Verdunkelungsvorrichtung für Fenster, insbesondere Rollladen. Die in Rede stehende Vorrichtung ist besonders für die Nachrüstung eines Rollladens mit einem motorischen Antrieb geeignet.First, the invention relates to a darkening device for windows, in particular shutters. The device in question is particularly suitable for retrofitting a roller shutter with a motor drive.

EINLEITUNGINTRODUCTION

Motorische Antriebe für Rollladen gibt es sowohl als Antriebe, die den Rollladenwickel mit Rollmotoren direkt antreiben als auch als Antriebe die den Rollladenwickel mittelbar über einen Gurt antreiben. Beim motorischen Gurtantrieb wird der Gurt von einem Gurtwickler angetrieben oder von einem Reibradgetriebe betätigt. Im Rahmen dieser Schutzrechtsanmeldung geht es um eine Antriebsvorrichtung für Rollladen mit einer Gurtbetätigung mit einem Gurtwickler. Die Antriebsvorrichtung ist als Nachrüsteinheit prädestiniert und kann den Rollladen motorisch betätigen. Hier geht es darum, den Bauraum der Antriebsvorrichtung stark zu verringern und den Montageaufwand beim Einbau des Rollladenantriebs am Fenster insbesondere dadurch zu reduzieren, dass die zu montierende Antriebsvorrichtung nicht mehr geöffnet werden muss.Motorized drives for roller shutters are available both as drives which directly drive the roller shutter winding with roll motors and as drives which indirectly drive the roller shutter winding over a belt. In the case of the motorized belt drive, the belt is driven by a belt winder or actuated by a friction gear. In the context of this patent application is concerned with a drive device for roller shutters with a belt actuation with a Gurtwickler. The drive device is predestined as a retrofit unit and can operate the roller shutter motor. The point here is to greatly reduce the installation space of the drive device and in particular to reduce the installation effort when installing the shutter drive on the window, that the drive device to be mounted does not have to be opened.

STAND DER TECHNIKSTATE OF THE ART

Der antriebstechnische Stand der Technik von Rollladenantrieben, die einen Gurt als Zugmittel zur Kraftübertragung benutzen, lässt sich unterteilen in Aufwickelantriebe, bei dem eine Wickeltrommel angetrieben wird und in Reibradantriebe, die den Gurt reibschlüssig antreiben. Der Reibradantrieb ist bezüglich der übertragbaren Kraft begrenzt. Alle bekannten motorisch betriebenen Rollladenantriebe benutzen den gebäudeseitig vorhandenen Gurt. Bei der Installation eines Rollladenantriebe mit einem Gurtwicklerantrieb muss der Gurt am vorhandenen Gurtwickler gelöst werden, um an der angetriebenen Wickeltrommel des Rollladenantriebs befestigt zu werden. Dem Vorteil der hohen übertragbaren Kraft infolge der formschlüssigen Verbindung zwischen Gurt und angetriebener Trommel steht sowohl der Nachteil des höheren Montageaufwandes durch die erforderliche Gurtbefestigung als auch der Nachteil des großen Raumbedarfs für die Wickeltrommel gegenüber.The drive technology prior art of roller shutter drives that use a belt as a traction device for power transmission, can be divided into take-up drives in which a winding drum is driven and in friction wheel drives that drive the belt frictionally. The friction wheel drive is with respect to the transmittable force limited. All known motorized roller shutter drives use the belt existing on the building side. When installing a roller shutter drive with a Gurtwicklerantrieb the belt must be solved on the existing Gurtwickler to be attached to the driven winding drum of the roller shutter drive. The advantage of the high transferable force due to the positive connection between the belt and the driven drum is opposed both by the disadvantage of the higher assembly costs due to the required belt fastening and the disadvantage of the large space requirement for the winding drum.

Erklärtes Ziel des vorliegenden Schutzrechtsbegehrens ist es, einen hoch belastbaren, formschlüssigen Wickelantrieb zu realisieren, der den Nachteil der üblichen, aufwendigen Gurtmontage nicht hat und einen geringeren Raumbedarf als üblich hat. Der Raumbedarf ist sehr wichtig, wenn man alle möglichen und damit auch die kleinsten genormten Wandschächte zur Aufnahme des Rollladenantriebs zulassen will. Darüber hinaus muss üblicherweise zur formschlüssigen Montage des Gurtes an der Wickeltrommel des motorischen Gurtantriebs das Gerät geöffnet werden, was diverse Sicherheitsmaßnahmen bei dem elektrischen Gerät erforderlich macht.The stated aim of the present patent application is to realize a highly resilient, positive winding drive, which does not have the disadvantage of the usual, expensive belt assembly and has a smaller footprint than usual. The space requirement is very important if you want to allow all possible and thus the smallest standardized wall shafts for receiving the roller shutter drive. In addition, the device must usually be opened for the positive mounting of the belt on the winding drum of the motorized belt drive, which makes various security measures in the electrical device required.

DAS NEUARTIGETHE NEW

Insbesondere geht es hier um nachrüstbare Rollladenantriebe mit einem Gurtantrieb. Das vorliegende Schutzrechtsbegehren soll bei einem formschlüssig arbeitenden, nachrüstbaren Wickelantrieb den geringen Montageaufwand und das geringe Bauvolumen dadurch ermöglichen, dass der gebäudeseitig vorhandene Gurt des Rollladens nicht identisch ist mit dem Zugmittel, welches zur Erzeugung der Antriebskräfte benutzt wird und im Rollladenantrieb aufgewickelt wird. Die neuartige Vorrichtung besitzt einen Gurtverlauf zwischen dem Antrieb und dem Rollladen der aus zwei hintereinandergeschalteten Gurten besteht, einem gebäudeseitigen Gurt, dessen Anfang an der Rollladentrommel befestigt ist und einem antriebsseitigen Gurt, dessen Anfang mit der motorisch betriebenen Vorrichtung verbunden ist. Beide Gurte werden bei der Montage des Antrieb an ihren Enden gekuppelt. Hierfür wird eine lösbare, formschlüssige Kupplung vorgesehen. Der vorrichtungsseitige Gurt ist etwa gleich breit, jedoch sehr dünn und hochfest. Diese Art von dünnen Gurten wären für eine Handbetätigung völlig unbrauchbar. Da jedoch durch den Einbau eines motorischen Antriebs der Handbetrieb beseitigt werden soll, bringt ein dünner, glatter, nicht griffgünstiger Gurt keine Nachteile mit sich. Der wesentliche Vorteil des dünnen Gurtes ist die Reduzierung des Wickeldurchmessers im Rollladenantrieb und der damit verbundene reduzierte Bauraum, da die Wickeltrommel im Antrieb wesentlich das Bauvolumen der Antriebsvorrichtung bestimmt.In particular, this is about retrofittable roller shutter drives with a belt drive. The present protective rights are intended to enable the low assembly costs and the low volume of construction in a form-fitting, retrofit winding drive, that the building side existing belt of the shutter is not identical to the traction means, which is used to generate the driving forces and is wound in the shutter drive. The novel device has a Gurtverlauf between the drive and the shutter which consists of two series-connected belts, a building-side belt, the beginning of the roller shutter drum is fixed and a drive-side belt, the beginning of which is connected to the motor-operated device. Both straps are coupled at the ends when mounting the drive. For this purpose, a detachable, positive coupling is provided. The device side strap is about the same width, but very thin and high strength. These types of thin straps would be completely useless for manual operation. However, since the manual operation is to be eliminated by the installation of a motor drive brings a thinner, smooth, not handy belt with no disadvantages. The main advantage of the thin belt is the reduction of the winding diameter in the roller shutter drive and the associated reduced space, since the winding drum in the drive significantly determines the overall volume of the drive device.

Die erfindungsgemäße Vorrichtung besteht aus einem motorisch betriebenen Antrieb mit einem geräteseitig installierten Gurt mit einer Gurtkupplung zur Befestigung am gebäudeseitigen Rollladengurt. In der deutschen Patentanmeldung mit dem Aktenzeichen 10 2005 041 293.4 ist ein Rollladenantrieb mit einem geräteseitig installierbaren Gurt beschrieben, wobei das Ziel, die Realisierbarkeit eines geringen Aufwickeldurchmessers des Gurtes und damit die Realisierbarkeit einer geringen Gerätegröße dadurch realisiert wird, dass der Rollladenantrieb ein Zugmittelgetriebe benutzt, welches den antriebsseitig erforderlichen Gurtweg für die Betätigung des Rollladens halbiert und durch die Verringerung der erforderlichen Gurtlänge den Wickeldurchmesser reduziert.The device according to the invention consists of a motor-driven drive with a belt installed on the device side with a belt coupling for attachment to the building-side roller shutter belt. In the German patent application with the file number 10 2005 041 293.4 is described a roller shutter drive with a device side installable belt, the goal of realizing a small Aufwickeldurchmessers the belt and thus the feasibility of a small size device is realized in that the roller shutter drive uses a traction mechanism, which halves the drive side required belt path for the operation of the shutter and reduces the winding diameter by reducing the required belt length.

Die vorliegende erfindungsgemäße Vorrichtung realisiert eine geringe Baugröße des Gerätes dadurch, dass ein geringer Aufwickeldurchmesser des Gurtes nicht durch Verringerung des Gurthubes, sondern nur durch die Verwendung eines hochfesten, dünnen Gurtes erreicht wird. Eine Verringerung der Gurtbanddicke hat eine deutliche Verringerung des Aufwickeldurchmessers zur Folge, was in der vorliegenden erfindungsgemäßen Vorrichtung eine wesentliche Voraussetzung zur Verringerung des Bauraums des Rollladenantriebs darstellt. Wenn jetzt der motorische betriebene Rollladenantrieb einen werkseitig installierten, dünnen Gurt besitzt, muss dieser an den vorhandenen Rollladengurt am Fenster angebunden werden. Diese Kupplungsstelle zwischen dem dünnen Gurt am Gerät und dem konventionellen Rollladengurt am Fenster stellt eine Dickstelle im gesamten Gurtverlauf dar, die auf keinen Fall in den motorischen Rollladenantrieb einlaufen sollte. Dieses Problem wird dadurch gelöst, dass bei der Montage des Rollladeantriebs der Rollladen sich in der oberen Position befindet, d.h. der Rollladen geöffnet ist. Erfolgt jetzt die Verbindung des geräteseitigen Gurtes mit dem fensterseitigen Gurt, so wird bei einer Betätigung des Rollladens die Kupplungsstelle der beiden Gurte nicht in den motorisch betriebenen Gurtwickler gelangen können. Die Kupplungsstelle der beiden Gurte kann bei einer Betätigung des Antriebs nur in den fensterseitigen Rollladenkasten einlaufen und in den Wickel integriert werden.The present inventive device realizes a small size of the device in that a small Aufwickeldurchmesser the belt is not achieved by reducing the Gurthubes, but only by the use of a high-strength, thin belt. A reduction in the webbing thickness results in a significant reduction of the winding diameter, which in the present inventive device an essential condition for reducing the space of the Shutter drive represents. Now, if the motorized roller shutter drive has a factory-installed, thin belt, it must be connected to the existing roller shutter on the window. This coupling point between the thin belt on the device and the conventional roller shutter on the window represents a thick spot in the entire belt, which should not run into the motorized shutter drive. This problem is solved in that during assembly of the roller shutter drive, the roller shutter is in the upper position, ie the shutter is open. If now the connection of the device-side belt with the window-side belt, so the coupling point of the two straps can not get into the motor-operated Gurtwickler upon actuation of the shutter. The coupling point of the two straps can run into an actuator of the drive only in the window-side roller shutter box and integrated into the winding.

Insbesondere bei Mietwohnungen ist die erfindungsgemäße Vorrichtung sehr vorteilhaft, da hiermit ein motorisch betriebener Rollladenantrieb einfach einbaubar und einfach ausbaubar ist. Die Gurte werden entkuppelt, der Gurtantrieb wird entfernt, der ursprüngliche Handwickler wird wieder eingesetzt und der ursprünglich getrennte Gurt wird wieder gekuppelt. Für diesen Fall ist es vorteilhaft, wenn das Kupplungsstück aus zwei Teilen besteht, einem werkseitig am dünnen, motorisch betriebenen Gurt befestigten Teil und einem, am fensterseitigen Gurt zu befestigenden Teil. Die Zweiteiligkeit der Kupplung ermöglicht eine lösbare formschlüssige Verbindung der Gurte und ergibt damit eine einfache Handhabung bei der Montage und bei der Demontage des Gurtantriebs. Ein zusätzliches Kupplungsstück wird an den demontierten Gurt des Handwicklers montiert, um den Rückbau auf den Handbetrieb des Rollladens bei einem Wohnungswechsel einfach zu gestalten.Especially in rental housing, the device according to the invention is very advantageous, since hereby a motorized roller shutter drive is easy to install and easy to remove. The straps are decoupled, the belt drive is removed, the original hand winder is replaced and the originally separate belt is coupled again. In this case, it is advantageous if the coupling piece consists of two parts, a factory attached to the thin, motor-driven belt part and a, to be fastened to the window-side belt part. The bipartite coupling allows a releasable positive connection of the straps and thus results in easy handling during assembly and disassembly of the belt drive. An additional coupling piece is mounted on the disassembled belt of the hand winder to make the dismantling of the manual operation of the roller shutter during a change of residence easy.

Wenn auch die Beseitigung der aufwendigen Gurtmontage und die Reduzierung des Bauraums der Wickeltrommel unter Beibehaltung der formschlüssigen Krafteinleitung in den Rollladengurt im Vordergrund stehen, so muss die erfindungsgemäße Ausführung der Antriebsvorrichtung noch weitere, vorteilhafte Merkmale ermöglichen.Although the elimination of the complex belt assembly and the reduction of space of the winding drum below Maintaining the positive force introduction into the roller shutter belt are in the foreground, so the inventive design of the drive device must allow even more advantageous features.

Diese wesentlichen mechanischen Merkmale sind:

  • 1. Bei dem erfindungsgemäßen, elektrisch betriebenen Rollladenantrieb muss beim Ein- und beim Ausbau nicht geöffnet werden.
  • 2. Als Zugmittel der erfindungsgemäßen Vorrichtung soll vorzugsweise ein hochfestes, dünnes Band verwendet werden, um den erforderlichen Bauraum der Vorrichtung gegenüber den gurtwickelnden Vorrichtungen deutlich zu verringern.
  • 3. Die Gurtzugkraft wird wegen des geringeren Bauraums nicht reduziert, da hier nicht wie üblich, eine schwächere und kleinere Antriebseinheit verwendet wird, sondern die Wickelvorrichtung verkleinert wird.
  • 4. Die erfindungsgemäße Vorrichtung erlaubt an allen Rollladentypen, auch bei den kleinsten normgerechten Wandschächten, eine Nachrüstung mit einem motorischen Gurtantrieb.
  • 5. Insbesondere für Mietwohnungen ist der Rollladenantrieb durch den einfachen Umbau sehr geeignet.
These essential mechanical features are:
  • 1. In the invention, electrically operated roller shutter drive does not need to be opened during installation and removal.
  • 2. As a pulling means of the device according to the invention preferably a high-strength, thin band should be used to significantly reduce the required installation space of the device relative to the belt-winding devices.
  • 3. The belt tension is not reduced because of the smaller space, since not as usual, a weaker and smaller drive unit is used, but the winding device is reduced.
  • 4. The device of the invention allows on all types of roller shutter, even with the smallest standard wall shafts, retrofitting with a motorized belt drive.
  • 5. Especially for rental housing, the roller shutter drive is very suitable due to the simple conversion.

In Figur 3 ist eine Kupplung für die Verbindung von zwei konventionellen Gurten dargestellt. Die Kupplungselemente sind zu der in Figur 2 dargestellten Kupplung kompatibel gestaltet. Dieser Umstand wird erforderlich, wenn beim Ausbau des handbetriebenen Rollladenwicklers bereits Vorkehrungen für den Rückbau auf Handbetrieb getroffen werden sollen. So wird das Kupplungselement (7) am rollladenseitigen Gurt befestigt, welches sowohl zum Kupplungselement (6) des motorischen Antriebs, als auch zum Kupplungselement (13) des Gurtes (14), welcher zum ausgebauten Handwickler gehört, kompatibel ist.FIG. 3 shows a coupling for the connection of two conventional belts. The coupling elements are designed to be compatible with the coupling shown in FIG. This circumstance becomes necessary if, when dismantling the hand-operated roller shutter winder, provision is already made for dismantling to manual operation. Thus, the coupling element (7) is attached to the roller shutter side belt, which is compatible both to the coupling element (6) of the motor drive, as well as the coupling element (13) of the belt (14), which belongs to the developed hand winder.
