Description

Die Erfindung betrifft einen Gurtwickler zur Aufputz und/oder Unterputzmontage für ein Gurtband oder ein Zugelement einer Verdunkelungsvorrichtung oder für ein Gurtband einer Verdunkelungsvorrichtung, die als Rollladen ausgebildet ist, mit einer Wickeltrommel, einer Wickeleinrichtung, einer elektrischen Antriebseinrichtung zum motorischen Auf- und Abwickeln des Gurtbandes und einer Steuerungseinrichtung sowie deren Bedien- und/oder Anzeigeelemente.The invention relates to a Gurtwickler for surface mounting and / or flush mounting for a webbing or a tension member of a darkening device or for a webbing of a darkening device, which is designed as a roller shutter, with a winding drum, a winding device, an electric drive device for motor winding and unwinding of the webbing and a control device and its operating and / or display elements.

Motorische Antriebe für Rollladen sind sowohl als Antriebe, die den Rollladenwickel mit sogenannten Rohrmotoren direkt antreiben als auch als Antriebe, die den Rollladenwickel mittelbar über ein Gurtband antreiben, bekannt. Beim motorischen Gurtantrieb, bei dem das Gurtband von einem Gurtwickler angetrieben wird, unterscheidet man Aufputz- oder Aufschraubwickler und Unterputzwickler, wobei letztere in einen Mauerkasten einsetzbar sind.Motor drives for roller shutters are both as drives that drive the roller shutter winding with so-called tubular motors directly as well as drives that drive the shutter roller indirectly via a webbing known. When motorized belt drive, in which the webbing is driven by a Gurtwickler, a distinction between surface or Aufschraubwickler and flush-mounted, the latter can be used in a wall box.

DE 34 43 989 A1 offenbart einen Gurtwickler für Rollläden. Der Gurtwickler weist eine Gurtwickeltrommel, einen Gurt und eine Freilaufkupplung auf. Durch die Freilaufkupplung wird bei zugentlastetem Gurtende und weiterdrehender Wickeltrommel der Kraftschluss zwischen dieser und dem Gurtende aufgehoben. DE 34 43 989 A1 discloses a Gurtwickler for shutters. The Gurtwickler has a Gurtwickeltrommel, a belt and a one-way clutch. By the overrunning clutch of zugentlastetem belt end and further rotating winding drum of the frictional connection between this and the belt end is repealed.

EP 0 092 118 A1 offenbart eine Verdunklungsvorrichtung mit einem Rollladen, einem Rollladenkasten, in dem eine erste Gurtwalze angeordnet ist, und mit einem Gurtkasten, in dem eine zweite Gurtwalze angeordnet ist. Ein Gurt ist sowohl an der ersten als auch in der zweiten Walze festgemacht und entweder auf der ersten oder der zweiten Walze aufgerollt. Bei geöffneter Verdunkelungsvorrichtung, ist der Gurt auf der zweiten Gurtwalze aufgerollt, und bei geschlossener Verdunklungsvorrichtung, ist der Gurt auf der ersten Gurtwalze aufgerollt. Beim Heraufziehen des Rollladens wird der Gurt von der ersten Gurtwalze abgewickelt und auf die zweite Gurtwalze aufgewickelt. Beim Herunterlassen des Rollladen verhält es sich umgekehrt. EP 0 092 118 A1 discloses a dimming device with a roller shutter, a roller shutter box, in which a first belt roller is arranged, and with a belt box, in which a second belt roller is arranged. A belt is secured to both the first and second rollers and rolled up on either the first or second rollers. When the blackout device is open, the belt is rolled up on the second belt roller, and with the blackout device closed, the belt is rolled up on the first belt roller. When pulling up the roller shutter, the belt is unwound from the first belt roller and wound onto the second belt roller. When lowering the roller shutter it is the other way around.

Beim Austausch eines elektrisch betriebenen Gurtwicklers oder eines handbetätigten Gurtwicklers gegen einen elektrisch betriebenen Gurtwickler stellt sich meist das Problem, dass bei der Montage desselben das vorhandene Gurtband nicht ohne weiteres auf die Wickeltrommel aufgefädelt werden kann, da sich die Wickeltrommel ohne das Herstellen einer elektrischen Verbindung meist nicht drehen lässt. Die Gefahr eines Stromschlages ist zudem bei geöffnetem Gurtwickler, dessen elektrische Verbindung bereits hergestellt wurde, sehr groß.When replacing an electrically operated belt winder or a hand-operated Gurtwicklers against an electrically operated Gurtwickler usually raises the problem that during assembly of the existing webbing can not easily be threaded onto the winding drum, since the winding drum without making an electrical connection usually do not turn. The danger An electric shock is also very large with an open Gurtwickler whose electrical connection has already been made.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Gurtwickler der angegebenen Gattung zu schaffen, der relativ einfach auch von Laien montierbar ist.The invention is therefore an object of the invention to provide a Gurtwickler the specified genus, which is relatively easy to install even by laymen.

Diese Aufgabe wird erfindungsgemäß durch einen Gurtwickler gelöst, der dadurch gekennzeichnet ist, dass der Gurtwickler einen Freilauf aufweist, der es ermöglicht, das Gurtband ohne das Herstellen einer elektrischen Verbindung auf die Wickeltrommel aufzufädeln.This object is achieved by a Gurtwickler, which is characterized in that the Gurtwickler has a freewheel, which makes it possible to unthread the webbing without making an electrical connection to the winding drum.

Zweckmäßige Weiterbildungen der Erfindung sind in den Unteransprüchen gekennzeichnet. Der erfindungsgemäße Gurtwickler zeichnet sich vor allem durch die relativ leichte Montierbarkeit aus, da das Gehäuse nach Abnahme des dieses verschließenden Deckels direkt an der Wand angeschraubt werden kann. Danach kann die Montage des vorhandenen Gurtbandes auf der in Aufwickelrichtung durch den Freilauf freidrehbaren Wickeltrommel erfolgen. Die einfache Gurtanbindung des Gurtbandes ergibt sich zum einen durch den Schlitz zwischen Wickeltrommel und Klemmleiste, die mit Widerhaken versehen ist, wobei das Gurtbandende lediglich in den Schlitz eingeschoben wird, und zum anderen durch die relativ gute Zugänglichkeit und Beweglichkeit der Wickeltrommel. Nach der anschließenden Herstellung der Spannungsversorgung ist der Gurtwickler bereits einsatzbereit.Advantageous developments of the invention are characterized in the subclaims. The Gurtwickler invention is characterized mainly by the relatively easy mountability, since the housing can be screwed directly to the wall after removal of this closing lid. Thereafter, the assembly of the existing webbing can be done on the freely rotatable in the winding by the freewheel winding drum. The simple Gurtanbindung the webbing results firstly through the slot between the winding drum and terminal block, which is provided with barbs, the Gurtbandende is merely inserted into the slot, and on the other by the relatively good accessibility and mobility of the winding drum. After the subsequent production of the power supply, the Gurtwickler is already ready for use.

Durch die bei Bedarf anbringbaren Distanzscheiben auf der Wickeltrommel an den Innenseiten der Gurtführungsscheiben ist es möglich, dass der Gurtwickler bei breiten und schmalen Gurtbändern zum Einsatz kommt. Dies verringert die Lagerhaltungskosten, da nicht unterschiedlichen Gurtwickler hergestellt und gelagert werden müssen.The attachable on demand spacers on the winding drum on the inner sides of the belt guide discs, it is possible that the Gurtwickler comes with wide and narrow straps used. This reduces the storage costs, since not different Gurtwickler must be manufactured and stored.

Der in den Figuren dargestellte Gurtwickler 1 für das Gurtband 2 o.dgl. Zugelement einer Verdunkelungsvorrichtung, insbesondere eines Rollladens o.dgl. weist im Wesentlichen eine Wickeleinrichtung 3, eine Antriebseinrichtung 4 aus Motor und Getriebe zum motorischen Auf- und Abwickeln des Gurtbandes 2 und eine Steuerungseinrichtung 5 sowie deren Bedienelemente 6, wie Tasten usw., und/oder Anzeigeelemente, wie Zeitschaltuhr (in den Figuren nicht dargestellt) auf, die gemeinsam in bzw. an einem Gehäuse 7 angeordnet sind, das mit einem Deckel 8 verschließbar ist. In dem Deckel 8 sind entsprechend den Bedienelementen 6 Öffnungen 9 vorgesehen, durch die die Bedienelemente 6 zugänglich sind bzw. aus dem Deckel 8 leicht hervorragen.The Gurtwickler 1 shown in the figures for the webbing 2 or the like. Tension element of a darkening device, in particular a roller shutter or the like. essentially comprises a winding device 3, a drive means 4 of motor and gear for motor winding and unwinding of the webbing 2 and a control device 5 and their controls 6, such as buttons, etc., and / or display elements, such as timer (not shown in the figures ), which are arranged together in or on a housing 7 which can be closed with a cover 8. In the cover 8 6 openings 9 are provided in accordance with the controls through which the controls 6 are accessible and slightly protrude from the lid 8.

Um das Gurtband 2 sehr einfach ohne das Herstellen einer elektrischen Verbindung auf der Wickeltrommel auffädeln zu können, verfügt der Gurtwickler 1 über einen Freilauf 12, der entweder zwischen der Wickeleinrichtung 3 und der Antriebseinrichtung 4 oder in der Antriebseinrichtung 4 vorgesehen ist.In order to be able to thread the webbing 2 on the winding drum very easily without establishing an electrical connection, the belt winder 1 has a freewheel 12 which is provided either between the winding device 3 and the drive device 4 or in the drive device 4.

Bei dem hier beschriebenen Ausführungsbeispiel ist die Wickeleinrichtung 3 direkt an dem Abtriebsrad 10 der Antriebseinrichtung 4 angeordnet und mit demselben um eine gemeinsame Mittelachse 11 drehbar. Dabei ist die Wickeleinrichtung 3 über den Freilauf 12 auf einer Lagerhülse 13 des Abtriebsrades 10 in Aufwickelrichtung a frei drehbar ausgebildet, was das Auflegen des Gurtbandes 2 auf die Wickeleinrichtung 3 wesentlich erleichtert, da in Abwickelrichtung dieselbe gesperrt bleibt.In the embodiment described here, the winding device 3 is arranged directly on the output gear 10 of the drive device 4 and with the same about a common central axis 11 rotatable. In this case, the winding device 3 via the Freewheel 12 on a bearing sleeve 13 of the driven wheel 10 in the winding direction a freely rotatably formed, which makes the laying of the webbing 2 on the winding device 3 much easier, as in the unwinding remains the same.

Dazu besteht die Wickeleinrichtung 3 aus einer auf der Lagerhülse 13 des Abtriebrades 10 gelagerten Wickeltrommel 14 mit seitlichen Gurtführungsscheiben 15, 16. Die zum Abtriebsrad 10 gerichtete Gurtführungsscheibe 15 weist an ihrem äußeren Umfang über demselben verteilt eine Vielzahl von federnden Sperrklinken 17 auf, die sich einseitig an Rastzähnen 18 am Abtriebsrad 10 abstützen und gemeinsam mit den Rastzähnen 18 den Freilauf 12 bilden. Vorzugsweise sind die Rastzähne 18 in einer seitlichen Ausnehmung 19 des Abtriebsrades 10 angeordnet.For this purpose, the winding device 3 consists of a mounted on the bearing sleeve 13 of the driven wheel 10 winding drum 14 with side belt guide disks 15, 16. The driven wheel 10 directed belt guide disk 15 has at its outer periphery over the same distributed a plurality of resilient pawls 17, which are unilaterally supported on ratchet teeth 18 on the output gear 10 and together with the ratchet teeth 18 form the freewheel 12. Preferably, the locking teeth 18 are arranged in a lateral recess 19 of the driven wheel 10.

Parallel zur Wickeltrommel 14 ist eine zwischen den Gurtführungsscheiben 15, 16 verlaufende Klemmleiste 20 vorgesehen, wobei in dem durch die Klemmleiste 20 und die Wickeltrommel 14 gebildeten Schlitz 21 das jeweilige Gurtbandende 22 aufgenommen wird. Dabei ist der Abstand zwischen Wickeltrommel 14 und Klemmleiste 20 bzw. die Höhe des Schlitzes 21 etwas geringer als die Dicke des jeweiligen Gurtbandendes 22.Parallel to the winding drum 14, a running between the Gurtführungsscheiben 15, 16 clamping bar 20 is provided, wherein in the slot 21 formed by the clamping bar 20 and the winding drum 14, the respective Gurtbandende 22 is added. The distance between the winding drum 14 and clamping bar 20 or the height of the slot 21 is slightly smaller than the thickness of the respective Gurtbandendes 22nd

Damit sich das Gurtbandende 22 nicht aus dem Schlitz 21 herausziehen kann, sind auf der zur Wickeltrommel 14 gerichteten Seite 23 der Klemmleiste 20 Widerhaken 24 vorgesehen.Thus, the Gurtbandende 22 can not pull out of the slot 21, 20 barbs 24 are provided on the side facing the winding drum 14 side 23 of the terminal block.

Damit mit dem Gurtwickler 1 unterschiedliche Gurtbänder 2 gewickelt werden können bzw. der Gurtwickler an unterschiedliche Breiten B von Gurtbändern 2 angepasst werden kann, können auf der Wickeltrommel 14 Distanzscheiben 25 aufgesetzt werden (nur in Fig. 4 dargestellt), die an den Innenseiten 26 der Gurtführungsscheiben 15, 16 anliegen und auf der Wickeltrommel 13 gelagert sind.Thus, with the Gurtwickler 1 different straps 2 can be wound or the Gurtwickler can be adapted to different widths B of straps 2, 14 spacers 25 can be placed on the winding drum (only in Fig. 4 shown), which rest against the inner sides 26 of the belt guide disks 15, 16 and are mounted on the winding drum 13.

Da die Wickeltrommel 14 mit den Gurtführungsscheiben 15, 16 vorzugsweise einstückig ausgebildet ist, bestehen die Distanzscheiben 25 jeweils aus zwei halbkreisförmigen Teilen 27. Am einen Ende 28 der geraden Kante 29 jedes halbkreisförmigen Teiles 27 ist eine über die Kante 29 überstehende Rastnase 30 vorgesehen, die nach dem Zusammensetzen zweier Teile 27 durch eine Öffnung 31 am anderen Ende 32 der geraden Kante 29 jedes halbkreisförmigen Teiles 27 ragt und an einem Steg 33 einrastbar ist. Durch die geteilte Ausbildung der Distanzscheiben 25 können diese bei Bedarf sehr einfach und schnell auf die Wickeltrommel 14 aufgesetzt werden. Die besondere Ausbildung der halbkreisförmigen Teile 27 aus zwei parallel angeordneten Seitenteilen 34 mit zwischen diesen vorgesehenen Verbindungsstegen 35 ermöglicht einen Zugriff auf die an dem Steg 33 eingerastete Rastnase 30, so dass die Distanzscheiben 25 bei Bedarf auch wieder entfernt werden können.Since the winding drum 14 is preferably integrally formed with the Gurtführungsscheiben 15, 16, the spacers 25 each consist of two semicircular parts 27. At one end 28 of the straight edge 29 of each semicircular member 27, a projecting beyond the edge 29 locking lug 30 is provided after the assembly of two parts 27 through an opening 31 at the other end 32 of the straight edge 29 of each semicircular member 27 protrudes and can be latched to a web 33. Due to the split design of the spacers 25, these can be placed very easily and quickly on the winding drum 14 if necessary. The particular design of the semicircular parts 27 of two parallel side members 34 provided with these connecting webs 35 allows access to the latched on the web 33 locking lug 30 so that the spacers 25 can be removed if necessary, again.

Zur Montage des Gurtwicklers 1, der in den Fign. als Aufputz-Gurtwickler dargestellt ist, wird zunächst der Deckel 8 von dem Gehäuse 7 entnommen. Fig. 3 zeigt den Gurtwickler mit entnommenem Deckel 8 im Montagezustand. Danach wird der Gurtwickler 1 an seiner zugedachten Position nach dem Anzeichnen und Bohren von Löchern mit Befestigungsschrauben an der Wand befestigt. Ggf. werden dann die Distanzscheiben 25 auf der Wickeltrommel 14 angebracht. Das Gurtbandende 22 wird nun über die Austrittsöffnung 36 am Gurtwickler 1 in das Gehäuse 7 eingeführt (siehe auch Fig. 5a). Über jeweils eine Öffnung 37 im Gehäuse 7 ober- und unterhalb der Mittelachse 11 der Wickeleinrichtung 3 ist dieselbe frei zugänglich, sodass das Gurtbandende 22 auf die Wickeltrommel 14 aufgelegt bzw. in den Schlitz 20 21 zwischen Wickeltrommel 14 und Klemmleiste 20 eingefädelt werden kann (siehe auch Fig. 5b). Danach wird die Wickeltrommel 14 in Aufwickelrichtung a soweit gedreht, dass sich das Gurtband 2 nicht mehr von der Wickeltrommel 14 lösen kann (siehe auch Fig. 5c).For mounting the Gurtwicklers 1, in the Fign. is shown as a surface Gurtwickler, the lid 8 is first removed from the housing 7. Fig. 3 shows the Gurtwickler with removed cover 8 in the assembled state. Thereafter, the Gurtwickler 1 is attached to its intended position after marking and drilling holes with mounting screws on the wall. Possibly. then the spacers 25 are mounted on the winding drum 14. The belt end 22 is now introduced via the outlet opening 36 on the Gurtwickler 1 in the housing 7 (see also Fig. 5a).
