Definitions

  • the winding shaft, on which the roller shutter curtain of a roller shutter is wound is driven with a belt, the part of the belt that is not required being wound onto a disk.
  • the disc is spring-loaded.
  • a belt brake is provided at the inlet to the belt winder.
  • the belt brake is controlled by the belt itself. To open it, the belt must be pulled out into the belt winder at a certain angle.
  • EP 0 860 579 describes a retrofittable drive for described a roller shutter belt.
  • the retrofittable drive consists of a gearbox that has two boards connected to each other by a back plate. A total of three rollers are rotatably mounted between the boards.
  • the roller shutter belt coming from the winding shaft runs first over a loose roller, with which the movement of the roller shutter belt is sensed for a control, and from there over two friction rollers.
  • the friction roller that is closest to the loose roller is wrapped around in an omega shape.
  • the two friction rollers are rotatably coupled to each other via spur gears to increase the driving torque.
  • One of the two friction rollers is driven by a gear motor via a bevel gear.
  • roller shutter belts are only suitable for so-called concealed belt winders. Due to the location of the friction rollers, the brake device of the belt winder can only be triggered if the drive is mounted on the flush-mounted winder. This is the only way to create the belt course that keeps the belt brake released. After leaving the last friction roller, the roller shutter belt runs into the belt winder essentially at right angles to the wall surface.
  • the drive device With the help of the additional deflection roller on the outlet side of the drive device, it becomes possible to place the drive device very close to the belt inlet of the belt winder. This in turn creates a belt course between the deflection roller and the belt inlet of the belt winder, which allows the brake to be released in the belt winder.
  • the special arrangement of the two friction rollers in connection with the idler roller ensures a very large wrap angle, which can total up to 360 °.
  • the belt friction on the friction rollers can be calculated as if the belt were lying around a single roller. It is therefore possible to achieve the very large gross wrap angle, which corresponds almost to a full circle. In the other solution, there is no loose roll on the exit side. Instead, the two plates are provided with a pronounced recess, as a result of which the last friction roller adjacent to the belt winder protrudes downwards, as it were.
  • the belt winder can be placed in this recess or recess, as a result of which the roller shutter belt running off runs into the belt winder at the required angle and releases the brake there.
  • any existing housing cover is free of force and can be made from less durable material.
  • the gear is preferably designed as a spur gear with straight teeth. In this way, axial forces that could push the boards apart are avoided.
  • a small, permanently excited DC motor is preferred for the drive. This turns relatively quickly, so that a very high reduction is required up to the friction roller. Using as few steps as possible, it is preferred to provide a worm gear on the input side that provides a correspondingly large reduction. In addition, the worm gear has the advantage that the motor can be skillfully placed between the boards.
  • the first deflection roller is preferably used for this det, to generate clock signals to transmit the movement of the belt to electronics.
  • a particularly large wrap angle can be achieved if the outer diameter of the spur gear, which is coupled to the friction roller, is at most 20% larger than the outer diameter of the friction roller.
  • the diameter of the gear wheel is expediently chosen such that when two friction rollers and two corresponding spur gear wheels are used, the belt fits through with little play between the friction rollers.
  • FIG. 1 shows a window reveal with the drive device according to the invention, in a perspective view
  • 2 shows the drive device according to FIG. 1 with the housing shell removed, in a view from the front
  • Fig. 3 shows the drive device of FIG. 2 in a side view, cut along the line III-III of FIG. 1, and
  • FIG. 4 shows a further exemplary embodiment of the drive device according to the invention, in a representation similar to FIG. 3.
  • Figure 1 shows a window reveal 1 in which a window frame 2 is attached.
  • a wing frame 4 in which a window pane 5 is inserted, is hinged to the window frame 2 with the aid of two hinges 3.
  • a roller shutter belt 5 is provided which leads inwards through an opening 6 in the window frame 2 from the belt pulley of the winding shaft.
  • the roller shutter belt 5 runs through a drive device 7 and is wound on a belt winder 8.
  • the belt winder 8 sits on the inside of the window frame 2 and contains a rotatably mounted belt pulley which is pre-tensioned in the winding direction of the roller shutter belt 5 by a spiral spring. It also includes a belt brake that blocks pulling out until the roller shutter belt 5 runs into the belt winder 8 at an angle greater than approximately 20 ° with respect to the vertical.
  • the drive device 7 can be programmed with the aid of operating buttons 9.
  • the control buttons 9 are zen in a housing shell 11, which covers the inside of the drive device 7.
  • the drive device 7 is fastened by means of angles 12, which are screwed to the inside of the window frame 2, on the inside 2 so as to be pivotable about a vertical axis.
  • the housing shell 2 there are two flat, approximately rectangular boards 13 and 14, which are integrally connected to one another on the side facing the window frame 2 by a flange or back 15.
  • a fastening tab 16 is notched out of the flange 15 in a central region.
  • the fastening tab 16 protrudes between the two boards 13 and 14 and extends at a right angle to the flat back flange 15.
  • the flange 15 merges into two further push-on tabs 17 and 18 which run parallel to one another.
  • the push-on tabs 17 and 18 serve as guide tabs for holding the housing shell 11, which contains corresponding guide grooves for this purpose.
  • the gear train of a transmission 19 is contained between the fastening tab 16 and the lower slip-on tab 18.
  • the drive takes place with the help of a permanently excited electric motor 21, which is fixed with its end face 22 on the mounting bracket 16 and projects with its armature shaft 23 downwards through a corresponding hole in the bracket 16 in the direction of the slip-on bracket 18.

  • the torque in the area of the spur gear 32 of the intermediate gear 29, however, is smaller, so that the tooth width can also be smaller.
