  Antriebsvorrichtung für ein Zugorgan 
 EMI1.1 
 

 <Desc/Clms Page number 2> 

    und--2-- zwischen   beiden Rollen liegt. Der   Gegenrolle --9-- ist   ein   Tastschalter --l2-- zugeordnet,   der von einer auf dem   Gurt --2-- angeordneten Verdickung --13-- zum   Abschalten des   Elektromotors--8--in   der oberen Endstellung des Rolladens gesteuert wird. Auf den   Gurt--2--   ist ausserdem ein Streifen--14--aufgesetzt, der aus einem auf der Antriebsrolle --4-- gleitfähigen Werkstoff besteht. Die   Verdickung--13--hat   einen derartigen Abstand von dem Streifen--14--, dass dieser beim Betätigen des   Tastschalters --12-- durch   die   Verdickung --13-- an   der Antriebsrolle --4-- anliegt.

   Der   Streifen--14--ist   zweckmässigerweise aus einem Gummiband hergestellt, das mit einer auf der Antriebsrolle --4-- gleitfähigen aufvulkanisierten   Schicht--14'--   versehen ist (Fig. 2). Diese Schicht--14'--besteht vorzugsweise aus dem unter dem Markennamen Teflon bekannten Werkstoff. Die der Antriebsrolle --4-- zugeordnete Oberfläche des Streifens --14-- hat Rillen --15--, die quer zur Längsrichtung des   Gurtes--2--verlaufen.   Dadurch wird vermieden, dass der Gurt durch das Aufbringen des Streifens steif wird. 



   PATENTANSPRÜCHE : 
1. Antriebsvorrichtung für ein Zugorgan, insbesondere für den mit der Welle eines Rolladens verbundenen Gurt, mit einem Gehäuse, in welchem eine vom Zugorgan mindestens teilweise umschlungene Antriebsrolle drehbar gelagert ist, die von einem Elektromotor angetrieben wird, 
 EMI2.1 
 (4) gleitfähigen Werkstoff bestehender Streifen (14) angeordnet ist, dessen Länge etwa der Länge des die Antriebsrolle (4) umschlingenden Abschnitts des Zugorganes (2) entspricht.

  Drive device for a pulling element
 EMI1.1
 

 <Desc / Clms Page number 2>

    and - 2-- lies between the two roles. The counter roller --9-- is assigned a pushbutton switch --l2--, which by a thickening --13-- arranged on the belt --2-- for switching off the electric motor - 8 - in the upper end position of the roller shutter is controlled. In addition, a strip - 14 - is placed on the belt - 2-- and consists of a material that can slide on the drive roller --4--. The thickening - 13 - is at such a distance from the strip - 14 - that it rests against the drive roller --4-- through the thickening --13-- when the pushbutton switch --12-- is pressed.

   The strip - 14 - is expediently made from a rubber band, which is provided with a vulcanized layer - 14 '- that can slide on the drive roller - 4 - (Fig. 2). This layer - 14 '- is preferably made of the material known under the brand name Teflon. The surface of the strip --14-- assigned to the drive roller --4-- has grooves --15-- which run transversely to the longitudinal direction of the belt - 2 -. This prevents the belt from becoming stiff when the strip is applied.



   PATENT CLAIMS:
1. Drive device for a pulling element, in particular for the belt connected to the shaft of a roller shutter, with a housing in which a drive roller at least partially wrapped around by the pulling element is rotatably mounted and driven by an electric motor,
 EMI2.1
 (4) slidable material of existing strips (14) is arranged, the length of which corresponds approximately to the length of the section of the pulling element (2) which wraps around the drive roller (4).
