Definitions

  • the present invention relates to a bracket for positioning a roller shutter tube in a roller shutter box, a roller shutter support comprising such a bracket and a mounting sub-assembly comprising two such roller shutter supports. It also relates to a method for mounting such a sub-assembly in a roller shutter box. The invention finally relates to a closing or solar protection installation comprising a rolling shutter.

  • the safe can be located inside the building or outside, and the safe can optionally be partially or totally integrated into the masonry and/or the insulation added to the masonry.
  • a roller shutter During assembly or disassembly of a roller shutter, an operator accesses the inside of the trunk to assemble the various parts therein which position and operate the elements of the roller shutter. To reduce the number of parts to be assembled and to facilitate the assembly operation, it is known to FR-A-2896530 to provide roller shutter supports comprising a flange assembled with a fitting to position the rolling tube of the roller shutter within the trunk. However, the assembly or disassembly of such a roller shutter requires opening the trunk completely.
  • roller shutter boxes are increasingly reduced in size, are increasingly airtight and incorporate thermal insulation elements made, for example, of expanded polystyrene or extruded. These chests are sometimes integrated into the structure of the wall. For these reasons it is difficult to open the box, for example during a maintenance operation, unless the thermal performance of the box is degraded or the wall has to be refinished. The roller shutter housed inside the trunk is thus difficult to access and the maintenance operation complicated to perform.
  • EP-104 5107-A1 describes a roller shutter shaft support, comprising two separate parts, assembled with each other by interlocking metal tabs.
  • the assembly of the roller shutter can be done without dismantling the box, however, the operation installation of such a support in a roller shutter box is difficult or even dangerous, because the support is unstable, and the two parts risk coming apart.
  • the invention more particularly intends to remedy, by proposing a device for positioning a roller shutter tube which is easy to assemble and disassemble, in complete safety.
  • the invention relates to a bracket for positioning a roller shutter tube in a roller shutter box, the bracket comprising a flange and a fitting.
  • the flange is formed in a first plate, defines a first longitudinal axis and includes a receiving hole for a bearing of the roller shutter tube.

  • the positioning tab comprises guide means which limit the amplitude of the tilting angle.
  • the flange comprises a first axle hole
  • the fitting comprises a second axle hole
  • the flange being pivotally mounted on the fitting by means of a fixing member which passes through the first and second pin holes
  • the guide means comprise an oblong slot, arranged in an arc of a circle centered on the first pin hole
  • the shutter can be put in place or taken down by passing through the lower slot of the trunk, in complete safety because the fitting and the flange are assembled together by a fixing member.
  • the risk of disassembly of the fixing lug is zero, which allows work to be carried out in complete safety.
  • the magnitude of the tilting angle is further limited by the oblong slot, which reduces the risk of mishandling and accidents.
  • the angle of tilting is easy to adjust in the position of use, the installation of the positioning bracket is easy and can be done manually, while the angle of tilting is easy to secure .

  • slides 28 not comprising movable walls 84, but only fixed walls, can also be used in the case of an installation of roller shutter 2 in external winding.
  • the fixing member 66 is a rivet. Other types of fasteners 66 are possible. According to a variant not shown, the fixing member 66 is a bolt. According to another variant not shown, the flange 38 and the fitting 11 are assembled to each other by riveting, the fixing member 66 then being formed by the plastically deformed part of one of the parts 38 and 11.
