Definitions

  • the invention relates to a roller shutter with a winding tube attached at one end to a driven winding shaft for winding and unwinding a curtain for opening and closing an opening and a coil spring biased at the other end between the winding tube and a fixed tensioning shaft for weight compensation of the curtain, whereby between the free end of the curtain and the winding tube, a tensioning device with tension members guided over deflection rollers is arranged.
  • a roller door of the type described above in which the tensioning device for the curtain consists of conical rope pulleys fastened on the winding shaft on both sides of the winding tube and pulley-like traction elements which are prestressed with a tension spring.
  • the tension springs are arranged between the pulleys of the pulley blocks and the foundation on both sides of the opening.
  • a roller shutter is known, on the curtain of which a guide rope is attached on each side, which leads back to the winding shaft via deflection rollers and can be wound up and unwound spirally in the opposite winding direction, the respective winding diameters of the guide cables and the curtain being approximately the same size due to the conically shaped winding disks.
  • This known roller shutter has no tensioning device to compensate for the difference in path of the curtain and the wound length of the guide cables on the winding disks. There is therefore a dependency between the diameter of the winding disks and the thickness of the curtain, so that the winding disks have to be adapted to the changing curtain thicknesses. In addition, changes in the length of the guide ropes and curtain cannot be compensated for by temperature fluctuations and wear.
  • a roller shutter for roof windows is known from DE-OS 28 42 381, the curtain of which is pretensioned with a tensioning device, for which two different exemplary embodiments are disclosed.
  • the tensioning device consists of a helical spring arranged in the winding tube, which is pretensioned between a sleeve connected to the winding tube and a shaft, on the outside of which two winding spools for pull cables connected to the curtain are fastened.
  • the connection between the shaft and the two winding spools is designed to be non-rotatable. With this arrangement, the curtain can be biased with the coil spring.
  • the two traction cables are connected to winding coils which are arranged in an oppositely rotatable manner on an axis and which are prestressed in the opposite direction of travel by a coil spring.
  • the torque of the coil spring should act in the unwinding direction, i.e. they become larger when the roller shutter is closed and become smaller when the roller shutter is opened.
  • the curtain can be pretensioned, but the changes in length of the pull ropes of different lengths cannot be compensated for, because the two take-up reels are not adjustable relative to one another, but are fixed in a rotationally fixed manner on the shaft.
  • roller shutter known from DE-OS 28 42 381 does not have a separate weight compensation in both embodiments of FIGS. 3 and 5, as is required for a heavy roller door.
  • the object of the invention is to create a roller door with a helical spring for balancing the weight of the curtain and a simply constructed tensioning device for the curtain, which has a long service life and does not represent a safety risk.
  • the leg springs can be countersunk in the open ends of the winding tube and encapsulated with them. It is also proposed to use belts for the tension members of the tensioning device, the material thickness of which corresponds approximately to the material thickness of the curtain. The length difference between the curtain and the traction elements to be compensated for by the leg springs can thus be minimized.
  • a prestressed coil spring for balancing the weight of the curtain is arranged on the side facing away from the drive between the winding tube and a fixed tensioning shaft arranged therein.
  • the curtain of the roller shutter could only be wound up and down at high speed with a correspondingly strong gear and drive motor.
  • a roller door designed according to the invention has the advantage that the tensioning device for the curtain can be pretensioned with two leg springs which are encapsulated in an existing structural part, namely the winding tube, and therefore do not require additional cladding.
  • the two torsion springs that are prestressed between the tensioning disks for the belts and the winding tube are only subjected to bending and therefore have a particularly long service life, which is also favored by minimizing the path difference between the belts and the curtain.
  • a frame 2 that laterally delimits an opening 1, there is a winding shaft 3 with a winding tube 4 concentrically fastened thereon, with which a transparent curtain 5 for closing the opening 1 can be wound up and unwound.
  • the winding tube 4 is fastened directly on the winding shaft 3 with a spring receptacle 7 which is offset inwards.
  • a tension pulley 8 for a belt 9 is freely rotatably mounted on the winding shaft 3.
  • a leg spring 10 is accommodated in the cavity between the spring receptacle 7 and the tensioning disk 8 and engages with its leg ends on the one hand in the spring receptacle 7 and on the other hand in the tensioning disk 8.
  • the belt 9 is guided over a deflection roller 11 and fastened at one end to the tensioning disk 8 and at the other end to a crosshead 12 connected to the curtain 5. In this way, the curtain 5 with the prestressed leg spring 10 can be kept under tension during winding and unwinding.
  • this tensioning disk 8 On the side facing away from the drive machine 6 there is also a tensioning disk 8 with a belt 9 for tensioning the curtain 5 with a further leg spring 10 arranges.
  • this tensioning disk 8 is not mounted on the winding shaft 3, but is freely rotatable on a tensioning shaft 13 for biasing a helical spring 14 for balancing the weight of the curtain 5.
  • the tensioning shaft 13 is guided through a spring receptacle 15 fixed inwards in the winding tube 4, so that the leg ends of the second leg spring 10 can engage on the one hand in the tensioning disk 8 and on the other hand in this spring receptacle 15.
  • the second leg spring 10 is also operatively connected to the winding shaft 3 via the spring holder 15, the winding tube 4 and the spring holder 7.
  • the coil spring 14 for the weight compensation of the curtain 5 can be pretensioned with a clamping ring 16 which is fixed to the frame 2.
  • the curtain 5 and the crosshead 12 engage through guides 17 in the frame 2, so that a tight seal of the opening 1 is guaranteed.
