Definitions

  • the invention relates to a roller shutter slat, a roller shutter curtain made of roller shutter slats and a roller shutter provided with it.
  • Rolling doors are known, for example, from the publications “Rolling doors and rolling grilles” and “Instructions for assembly, operation and maintenance” from Hörmann.

  • the slats or armored bars of the roller shutter curtain lie on top of each other.
  • comparatively pointed areas of the lamellae can come into contact with flat areas of the lamellae lying thereon. This can result in such high frictional forces that the surface of the slats is worn or even damaged. Furthermore, this can result in a high level of noise, particularly in the case of high-speed doors.
  • the invention is based on the basic idea of giving the roller shutter slat a suitable shape which can itself improve wear behavior. At the same time, the winding bale diameter can be improved.

  • Roller shutters have many advantages. They are space-saving, can be opened and closed vertically, and are quick and easy to assemble. A disadvantage of roller shutters is the damage to the slats when they are rolled up. The traces are usually created by pressing the ply rings on the upper lamellae and lamellas.

  • the difference to conventional roller shutter slats is also the hinge shape.
  • the hinge can be designed with an angle, which allows a larger inner and outer curvature.
  • the combination of hinge and curvature means that the slat can be wound with little edge contact and, as a result, fewer edge pressure points.
  • the new profile described here is also rounded on each side, which can further improve the winding ( Fig. 8 ).
  • the slats can safely rest on each other with two contact surfaces ( Fig. 7 ).

  • edge pressure points can be reduced, especially because the weight is distributed over surfaces.
