Definitions

  • the present invention relates to a roller shutter flange, a roller shutter installation comprising such a flange and a method of assembling such a flange.
  • these openings are generally equipped with a protection installation, for example against intrusions, with a screen such as a roller shutter, or a solar protection installation, with for example a screen such as a solar canvas, a roller shutter, a slatted blind or an adjustable sunshade, also known as "BSO", or even an anti-insect protection installation, with a mosquito net.

  • a screen such as a roller shutter
  • a solar protection installation with for example a screen such as a solar canvas, a roller shutter, a slatted blind or an adjustable sunshade, also known as "BSO”
  • BSO adjustable sunshade
  • the protective screen is attached to a tube, which is housed in a receiving volume arranged in the upper part of an opening.
  • the receiving volume is delimited by a casing of the roller shutter installation, or is arranged directly in the wall, for example in a lintel, etc.
  • the tube comprises two end bearings, which are each supported by a flange, so that the tube is pivotally mounted, relative to the flanges, around a winding axis.
  • the flanges are integral with the wall, generally fixed to other elements of the protective installation, in particular each fixed to a respective guide slide of the protective screen.
  • the installation generally includes a motor, which is housed in the tube and whose pivoting head protrudes from the tube, this head being fixed to the flange.
  • FR-2 917 452-A1 describes, for example, a flange comprising an attached plate, the plate having an orifice for receiving an axis of the tube. The axis is locked to the plate by means of a spring pin, which risks being lost and the installation of which can be difficult, because it requires perfect alignment of the parts.
  • FR-3 126 137-A1 describes, for its part, a roller shutter flange with a pendulum lock comprising relatively fragile indexing members.
  • the invention seeks to address more specifically by proposing a roller shutter flange which allows easier fixing of the end bearing of the winding tube.

  • a protection installation 10 is schematically represented on the figure 1 .
  • Installation 10 is here an intrusion protection installation, which includes a roller shutter. Protection installation 10 is therefore here a roller shutter installation.
  • the installation 10 is fixed on a wall 12, assumed to be flat and vertical, in which an opening 14 is provided which passes through the wall 12.
  • the opening 14 is here hidden by a protective screen 24, which belongs to the protective installation 10.

  • the installation 10 has a structure that is generally symmetrical with respect to a transverse plane T18 of the installation, the transverse plane T18 being orthogonal to the trunk axis A18.
  • the trunk 18 provides a receiving volume V18 for other parts of the installation 10, as described below.
  • the trunk 18 is manufactured by assembling boards.
  • the receiving volume V18 is delimited in part by the wall 12, for example is managed in the wall 12, in particular in a lintel delimiting the opening 14 in the upper part of the opening 14.

By extension, the trunk axis A18 is also a winding axis of the tube 20.

  • the notches 388 are formed in a hollow on the internal radial surface 385 of the ring 382, as illustrated in particular in FIG. figure 4
  • the ring 482 comprises notches 488, which are provided on an external radial surface 485 of the ring 482.
  • the notches 488 are open in a centrifugal direction to the winding axis A18.
  • the fixing portion 410 comprises a peripheral wall 414, which extends opposite the wall 314 delimiting the imprint 312 so as to delimit the annular volume V324.
  • the fixing portion 410 comprises front stops 422, which are arranged in projection from the peripheral 414 in the direction of the winding axis A18, the front stops 422 being configured to cooperate with the notches 488, in a manner analogous to the cooperation of the front stops 322 and the notches 388 of the first embodiment.
  • the locking part 480 here comprises three protrusions 386, which are arranged projecting from the ring 482 and which extend from the ring 482 towards the winding axis A18, in other words centripetally to the winding axis A18.
  • the fixing portion 410 here comprises three openings 416, which are arranged through the wall 314 and which open into the internal volume V314.
  • the locking part 480 comprises an axial protuberance 490, which is arranged as a projection on a front face 492 of the locking part 480, the front face 492 of the locking part 480 being oriented towards the front stops 422 when the locking part 480 is received in the annular volume V324.
  • the axial protuberance 490 is associated with one of the front stops 422 and cooperates with the associated front stop 422, in particular by complementarity of shapes, so as to index the movements of the locking part 180 between the assembled position and the locking position.
  • the axial protrusion 490 includes an upper face 494, which is configured to slide against the associated front stop 422 when the locking piece 480 is moved between the assembled position and the locking position.
  • the axial protuberance 490 advantageously has a ramp shape, which provides a front portion 496A and a rear portion 496B, which are angularly offset around the winding axis A18, the front portion 496A being opposite the associated front stop 422 when the locking part 480 is in the assembled position, as illustrated in FIG. figure 9 , while the rear portion 496B is opposite the associated front stop 422 when the locking part 480 is in the locking position, as illustrated in figure 11 .
  • the locking part 480 is shown in an intermediate position between the assembled position and the locking position.
  • a thickness of the front portion 496A is defined as being a distance, measured at the front portion 496A and parallel to the winding axis A18, between the upper face 494 and the front face 492 of the locking part 480.
  • a thickness of the rear portion 496B is defined as being a distance, measured at the rear portion 496B and parallel to the winding axis A18, between the upper face 494 of the axial protuberance 490 and the front face 492 of the locking part 480,
  • the axial protrusion 490 and the associated front stop 422 together form a non-return member, which prevents the disassembly of the locking part 480 once the locking part 480 is assembled to the portion 410, the locking part 480 being in the locking position or in the withdrawn position, or in an intermediate position between the locking position and the withdrawn position.
  • the axial protuberance 490 cooperates with the associated front stop 422, in particular by complementarity of shapes, so as to index the movements of the locking part 480 between the assembled position and the locking position.
  • the front portion 496A and the rear portion 496B have a similar thickness, while an intermediate portion of the axial protuberance 490, located between the front portion 496A and the rear portion 496B, has a thickness greater than that of the front portion 496A or the rear portion 496B.
  • the flange 300 comprises the fixing portion 310 and the peripheral portion 350, which are separate parts.
  • the structure of the flange is not limiting, and the principles of the invention can be transposed to other types of flange, for example when the fixing portion 310 is integral with the peripheral portion 350.
  • the materials and manufacturing methods of the fixing portion 310 and the peripheral portion 350 are then adapted accordingly.
  • the locking part 380 comprises the ring 382, which is captive to the connection portion 310, the movements of the locking part 380 relative to the connection portion 310 being a rotational movement about the winding axis A352.
  • the structure of the locking part is not limiting.
  • the locking part comprises a latch, which is captive to the fixing portion 310 and the movement of which relative to the fixing portion 310 is a translational movement in a plane orthogonal to the winding axis A18.
