Definitions

  • the present invention relates to a roller shutter slat according to the preamble of claim 1.
  • roller shutter slats are known in many embodiments.
  • the outer sides delimiting an inner chamber preferably consist of aluminum strip which is roll-formed.
  • roller shutter slats are provided with hooks which engage in the associated hooks of adjacent roller shutter slats in a form-fitting manner, so that an articulated connection is created which allows a perfect winding on a roller.
  • the curvature of the broad sides also contributes to this, the concavely curved side facing the roller being designated as the inside, while the convex side forms the outside.
  • roller shutter slats have a relatively thin wall, which, however, meets the necessary and required stability requirements, in particular against accidental deformation, does not do justice in every case.
  • the present invention is therefore based on the object of designing a roller shutter rod of the generic type in such a way that its load capacity is increased and the service life is extended.
  • roller shutter rod which has the features of claim 1.
  • the invention brings significant advantages with regard to reducing damage.
  • the inner chambers of the roller shutter bar formed by the web are foamed with a plastic, for example polyurethane.
  • the radius of the concavely shaped inside is approximately 48 to 50 mm and the radius of the convexly shaped To keep outside about 125 to 128 mm in size, with a width of about 77 mm and a thickness of about 25 mm.
  • the diameter of the roller on which the roller shutter bars are wound can be kept small, which results in a small space requirement within the roller shutter box, which is particularly advantageous where long roller shutters, for example for high window openings, are required.
  • the single figure shows a cross section through a roller shutter slat according to the invention.
  • a roller shutter rod 1 which has a concavely curved inside 3 and a convexly curved outside 2.
  • Both the outside 2 and the inside 3 consist of an aluminum band, which is brought into the corresponding shape by roll forming, the inside and outside 3.2 being connected to one another by folding on their top and bottom.
  • This fold area is designed in the form of a hook 5, in which a hook of a further, adjacent roller shutter bar, which is shown in broken lines, engages, so that an articulated connection results.
  • the inside 3 of the roller shutter rod 1 is shaped such that a web 4 is formed which extends transversely to the height of the roller shutter rod, which is preferably 77 mm, to the outside 2.
  • the thickness of the roller shutter slat 1 is 25 mm in the present exemplary embodiment, while the radius of the concave inner side 3 is 48.9 mm and that of the convex outer side 2 is 126.8 mm.
  • two inner chambers 6 are formed, which are foamed with a plastic, for example polyurethane.
  • the web 4 can be connected to the outside 2, for example, by gluing.
  • a particularly stable design of the web 4 is obtained when it is doubled, as can be seen in the figure.
  • the doublings can be perforated or the like. be connected.
  • the perforation in the area adjacent to the outside 3.
  • the doubling parts can also be glued together to increase stability.
