Definitions
- Manually operated shutters have one running in front of the wall Roller shutter belt with which the roller shutter armor closes is moving.
- the roller shutter belt is at one end on a winding disc attached, which in turn rotatably with the winding shaft of the roller shutter is connected.
- the other end of the Roller shutter belt leads to a belt winder that is in the Usually in a pocket in the wall next to each Window is located.
- the belt winder has a rotatably mounted Disc on which the belt end is attached. With The disc is wound in the winding direction with the help of a clock spring of the belt pretensioned.
- the known drive device serves the roller shutter belt to be driven by an electric motor. For this she will retrofitted in the wall above the pocket in which the automatic rewinder is located.
- the known drive device has a circuit board on, in which three friction rollers axially parallel to each other are stored. At least two of these friction roles are coupled with each other via gears so that their Driving surfaces run at the same peripheral speed.
- One of the take-up rolls is removable to form an S-shaped one To enable wrapping of the roles without the Roller shutter belt can be threaded through between the roller got to.
- the coil spring is the belt pulley in which the belt winder is to be tensioned in the winding direction, lame and unable to develop a sufficient train.
- the roller shutter belt is at its other end Do not open the roller shutter curtain with sufficient force pressed the friction rollers, especially not against the running friction roller so that the transport breaks down. As a result, the loose roll also remains, with which the movement of the roller shutter belt is sensed the end position when fully lowered To register roller shutters. The control switches the drive because she thinks the roller shutter curtain has an end position reached.
- the drive device is a Pressure device available, with the help of the roller shutter belt to the friction or driving surface of those Friction roller is pressed, over which the roller shutter belt the drive device in the direction of the storage area, say the belt winder, or the location of the original Belt winder leaves.
- This friction roller is from the Roller shutter winding shaft from the perspective of the drive function as far away as possible.
- the roller shutter belt also held pressed against the driving surface when no train is developed on the output side, because on the acceptance side because of the lame clock spring or the missing Belt windlickers no longer have any pulling force is.
- the friction roller can be used together with the pressure device develop a certain traction that continues at the "upstream” friction rollers for sufficient Pressure force ensures. That direction is under "upstream” meant that counter to the movement of the roller shutter belt is directed when the shutter curtain is raised. The The roller shutter belt can still be transported.
- the pressure device can be made from a single leaf spring be formed or a pressure roller that is resilient biased against the friction roller in question is.
- a particularly good entrainment effect can be achieved if the pressure roller is also positively driven is the driving surface of the friction roller runs at the same peripheral speed as the pinch roller. There are then no retarding forces the roller shutter belt, which is carried by the friction roller could hinder.
- the pressure device can be optionally on the board or be anchored in the housing. Anchoring in the housing has the great advantage that when installing the drive device the roller shutter belt is not between the friction roller and the pressure device must be threaded. The pressure device, which is located in the lid and was removed with this, does not hinder the assembly.

- the tension in the roller shutter belt 2 stops.
- the Roller shutter belt 2 lifts slightly from the idler roller 33.
- the idler roller 33 comes to a standstill, causing the control electronics evaluates and switches off the motor current 27.
- the Roller shutter belt is now at least in the area between the upper friction roller 13 and the winding shaft of the roller shutter almost free of tension.
- the belt winder pulls with a corresponding force. Should If he works properly, he creates on the friction roller 13 one to the friction on the two friction rollers 14 and 15, reduced traction and abilities. Should the belt winder being lame almost creates it at all no force, so practically no friction between the roller shutter belt 2 and the driving surfaces 17 and 21 comes.
- the roller shutter belt 2 can be tensioned and be taken away, the increasing tension in the Roller shutter belt 2 above the driving surface 17, based on the installation position, the contact pressure on the driving surfaces 17, 21 and 24 reinforced to a level sufficient to meet the Roller shutter belt 2 down towards the drive device 1 pull, which raised the roller shutter curtain becomes.
- the arrangement according to the invention can also be used operate without any belt winder.
- the belt winder completely from the Remove the wall and with the roller shutter curtain lowered Roller shutter belt a suitable distance below the drive device 2 cut off.
- the free end of the now Roller shutter belt 2 is in the manner shown in Figure 2, threaded between the friction rollers 13, 14 and 15 and through the slot 12 into the now empty Pocket inserted in the wall.
- the pressure device 45 is effective and permitted the desired transport and movement of the roller shutter belt 2 completely independent of the belt winder.
- opening the The shutter belt 2 will look like a roller shutter armor fold in the pocket in the wall.
- the driving surfaces 17, 21, 24 and 35 are slightly larger than the maximum width of the Roller shutter belt 2 corresponds. Accordingly, the Width of the leaf spring 46 selected so that the roller shutter belt 2 over the widest possible area against driving space 24 is pressed.
- Fig. 3 shows another embodiment of the pressure device 45.
- the pressure device 45 according to FIG. 3 consists of a flexible support 48, which also again consists of a leaf spring material. An end, the end 49 is for reception in the holder 47 of the cover 4 provided. At the other end two tabs 45 are bent, between which a pressure roller 52 is rotatably mounted is.
