Definitions

  • the invention relates to a roller shutter slat, consisting of a hollow chamber profile deflected to the roller shutter width with two coincidently curved, outwardly curved main sections, which at one end are bent towards each other inwards and then towards each other outwards with subsequent formation of a double-walled hook, on the other towards the outside concave longitudinal section bent end the band edges encompass each other, and the other ends are connected to form a profile open and rounded at the bottom in a circular shape for receiving the hook on the next roller shutter rod, the substantially parallel side walls of the Chamber are formed by sharp-edged bending back of the profile main sections and the back bending on the one main section at the end bent into the chamber of a double-walled counter hook for the hook of the next roller shutter tabes is located.
  • the invention has for its object to provide a roller shutter rod of the type specified in the introduction, which ensures with a large cover width that the wound roller shutter armor has a relatively small diameter.
  • the hollow chamber profile consists of metal.
  • the hollow chamber profile can consist of aluminum, steel or plastic.
  • the hollow chamber profiles made of metal are foamed with plastic.
  • the counter hook is arranged at 25 ° to the vertical in the direction of the chamber.
  • the advantages achieved with the invention consist essentially in the fact that a relatively small winding diameter of the roller shutter curtain is given with a large covering width.
  • the inventive design of a roller shutter rod means that less material is required (smaller sheet width), which is particularly noticeable when the roller shutter rod is rolled from aluminum strip. Thanks to the new shape of the roller shutter slat, the wall of the hollow chamber profile (made of aluminum) can be made thinner with the same stiffness as before. With the new profile, the shoulder slope (inside of the profile) has been greatly enlarged, which prevents the neighboring profile from being caught when it is rolled up. The purpose of this is also to coordinate the covering width and the radius of curvature of the outer main section.
  • a coordinated inclination of the hook handle relative to the inclination of the chamber results in an absolute opacity when the roller shutter curtain is pushed together; the upper hook shoulder is pulled against the drip nose of the neighboring profile, the lower hook shoulder against the inclined outer wall of the chamber.
  • the hollow chamber profile 2 according to the invention is shown in front view, indicating the profile dimensions characteristic of the invention and their permissible tolerances.
  • the wall thickness 1 of the hollow chamber profile 2 can be chosen to be smaller than in previously known profiles: while in the invention the wall thickness 1 is approximately 0.5 mm, the wall thickness is in a comparable known profile 0.6 mm. This is particularly important when, as is practiced on a large scale today, the hollow chamber profile consists of rolled aluminum strip.
  • the optimization of the dimensions of the hollow chamber profile 2 according to the invention also has the consequence that a smaller sheet width than previously can be selected for aluminum in strip form for roll forming the hollow chamber profile 2, which in addition to the lower material thickness (wall thickness 1) equates to additional material savings.
  • the hollow chamber profile 2 has a central cavity 12, at one end of which the hook 7 and at the other end an outwardly open chamber 9 with a counter hook 10 is arranged.
  • the central cavity 12 is located between an outer main section 4, the radius of curvature of which is 72 mm, and an inner main section 5, whose radius of curvature is 46 mm.
  • the deck width 3 is 58.95 mm, which is a significant improvement over a conventional profile, where the deck width is 55 mm.
  • roller shutter armor which is composed of profiles according to the invention: compared to a roller shutter armor made of a comparable known profile with a predetermined height of the armor (2500 mm), using the hollow chamber profile 2 according to the invention results in a minus of approx. 20 mm of the rolled-up roller shutter armor, which means a considerable reduction in practice.
  • the distance between the main sections 4 and 5 is 7.2 mm at the narrowest point.
  • the hook 7 has a length of 9.75 mm and an outer width at the hook head of 5.3 mm and is inclined with its straight shaft relative to the longitudinal extension 8 by 2.88 ° in the direction of the inner main section 5.
  • the chamber 9 has between the side walls a width of 5.4 mm and a length, measured from the back bend of the outer main section 4 to the chamber bottom, of 10.7 mm and the counter hook 10 is 3 ° in the direction of the longitudinal extension 8 outer main section 4 inclined.
  • the counter hook 10 can be arranged at 25 ° to the vertical in the direction of the chamber 9.
  • the profile height 11 of the hollow profile 2 is 14.5 mm.
  • the covering width 3 and the radius of curvature of the outer main section 4 are coordinated according to the invention, as a result of which jamming of the profiles lying on one another during the winding is excluded.
  • the described inclination of the hook 7 in relation to the inclination of the counter-hook 10 leads to opacity when the roller shutters are pushed together.
