Definitions

  • the present invention relates to a roller shutter flange, a protective installation, in particular for a roller shutter comprising such a flange and a method for assembling such a flange.
  • these openings are generally equipped with a protective system, for example against intrusions, with a protective screen such as a roller shutter, or a solar protection system, with for example a screen such as a solar canvas, a roller shutter, a slatted blind or an adjustable sunshade, also called "BSO", or even an insect protection system, with a mosquito net.
  • a protective system for example against intrusions
  • a protective screen such as a roller shutter, or a solar protection system
  • a screen such as a solar canvas, a roller shutter, a slatted blind or an adjustable sunshade, also called "BSO”
  • BSO adjustable sunshade
  • the protective screen is attached to a tube, which is housed in a recess created at the top of an opening.
  • This recess may be defined by the roller shutter housing or directly within the wall, for example, in a lintel.
  • the tube has two end bearings, each supported by a flange, allowing the tube to pivot relative to the flanges around a winding axis.
  • the flanges are fixed to the wall, typically attached to other components of the protective system, each specifically to its respective guide rail for the screen.
  • the size of this winding depends on factors such as the tube diameter, the type of screen, and the window height.
  • the position of the winding axis relative to the flanges is adjusted according to the winding size, specifically to reduce friction between the screen and other parts of the protective system during winding and unwinding movements around the tube.
  • FR-2 893 348-A1 For example, it describes a flange with three mounting recesses for a winding tube bearing. The recesses are small, which limits the tube mounting options. In particular, this flange is not compatible with motorized winding tubes, which require larger diameter recesses to transmit motor torque.
  • EP-1 184 534-A2 Or FR-2 993 918-A1 describe each other prior art roller shutter flanges, with a fixing portion, including a recess configured to receive a tube end bearing winding and a peripheral portion, which is configured to be secured to the rest of the roller shutter installation, the fixing portion including adjustment notches in the position of the fixing portion relative to the peripheral portion.
  • the invention intends to remedy in particular, by proposing a roller shutter flange which allows fine adjustment of the position of the winding tube relative to the flanges, while being compatible with large bearings, for example motor bearings.
  • the invention relates to a flange, configured to support a winding tube of a protection installation, in particular a roller shutter.
  • the position of the fixing portion relative to the peripheral portion along the adjustment axis is incrementally adjustable, with an adjustment step corresponding to one step between two successive notches.
  • the adjustment step depends on the shape of the notches and teeth, allowing for finer adjustment compared to known prior art devices, in particular, adjustment independent of the size of the impression that accommodates the bearing.
  • a protection installation 10 is schematically represented on the figure 1 Installation 10 is an intrusion protection system, which includes a roller shutter. Therefore, this protection system is a roller shutter installation.
  • the installation 10 is fixed to a wall 12, assumed to be flat and vertical, in which an opening 14 is provided, passing through the wall 12.
  • the opening 14 is covered by a protective screen 24, which belongs to the protective installation 10.
  • the protective screen 24 is here a roller shutter curtain.
  • the screen 24 is a solar shade, or even a mosquito net, etc.
  • Installation 10 includes a box 18, which is schematically represented here with dashed lines.
  • the box 18 is fixed to the wall 12, above the opening 14.
  • the box 18 has an elongated, generally parallelepiped shape and extends along its length along a box axis A18.
  • the box axis A18 is assumed to be horizontal. The description is based on the orientation of the components of installation 10 as shown in the drawings, although this may differ in reality.
  • Installation 10 has a generally symmetrical structure with respect to a transverse plane T18 of the installation, the transverse plane T18 being orthogonal to the box axis A18.
  • the chest 18 provides a receiving volume V18 for other parts of the installation 10, as described below.
  • the chest 18 is made from an assembly of boards.
  • the receiving volume V18 is partially delimited by wall 12, for example, within wall 12, specifically within a lintel that defines the upper part of opening 14. This configuration corresponds to a so-called “tunnel” installation.

  • the tube 20 comprises two opposite ends, each of which is equipped with an end bearing 22.
  • Each of the end bearings 22 is supported by a respective support 30, so that the tube 20 is pivotally mounted relative to the supports 30, around the trunk axis A18.
  • An upper end 25A of the screen 24 is attached to the tube 20, here by means of two locks 26 belonging to the installation 10. It is understood that according to the direction of rotation of the tube 20 around the trunk axis A18, the screen 24 winds around the tube 20, or unwinds, a lower end 25B of the screen 24 rising or falling in front of the opening 14. By extension, the trunk axis A18 is also a winding axis of the tube 20.
  • the rotation of tube 20 is controlled by a user via a drive device.
  • the drive device is not shown.
  • the drive device is either manual, for example with a crank and a gear system or with a belt drive, or motorized, with an electric motor.
  • part of the motor is usually housed within the tube 20, while a pivoting head of the motor protrudes from the tube and forms one of the tube's bearings.

  • the installation 10 thus comprises two tracks 32, which are located opposite each other, symmetrically with respect to the transverse plane T18.
  • Each track 32 extends vertically along one side of the opening 14, the two tracks 32 serving to guide the screen 24, particularly during the raising or lowering movements of the lower end 25B of the screen 24.

  • each flange has a symmetrical shape with respect to a plane orthogonal to the adjustment axis A352; in particular, each peripheral portion includes two recesses for receiving the mounting tabs for the corresponding slide. Peripheral portions of the same type can thus be used for both supports of the protective installation, thereby reducing the number of different spare parts.
