Definitions

  • the present invention relates to a roller shutter system comprising a roller tube and a lock.
  • the invention also relates to a roller shutter installation comprising such a system.
  • Roller shutters are used at building openings, such as windows. They are mainly used to adjust the brightness inside a room by adjusting the height of the shutter or, depending on the model, by tilting the slats of the apron.
  • a roller shutter installation generally comprises a box arranged in the upper part of the opening.
  • a roll-up tube for the shutter is arranged in this trunk.
  • the invention relates more particularly to the mechanical connection between the apron of the roller shutter and the winding tube of the roller shutter.
  • roller shutters are relatively vulnerable to burglary attempts. With basic models, burglars usually only need to reach their hand or a thin tool under the last slat to lift the roller shutter and gain access to the window. This is why some roller shutter installations, especially those in single-family houses and ground-floor apartments, include a lock.
  • the lock is a device which automatically prevents the curtain from being raised from the completely lowered position, by an external action, such as an attempted break-in for example, other than a normal action on the maneuvering device, by means of a winch or motor. Thanks to the presence of these locks, roller shutters can be used as a means of protection preventing intrusion inside the building.
  • a known method of fixing the lock to a roller shutter is to use fixing elements such as screws.
  • FR 2 831 596 A1 discloses a system in which the lock has three articulated links, of which a rear link is configured to be attached to an upper blade of the shutter and a front link is configured to be attached to the outer surface of the tube.
  • the winding tube is provided with a projecting longitudinal groove, the front link having on an internal face a shape suitable for fitting, by elastic deformation of the front link, the front link on the groove of the tube.
  • the front link comprises locking lugs mounted facing each other, these lugs cooperating with openings made in the radial surfaces of the groove.
  • this system requires considerable force during assembly, as well as during disassembly, requiring the use of a tool, such as a screwdriver, to lever the wall of the tube and disassemble the front link.
  • a tool such as a screwdriver
  • such a system mounted projecting on the tube is relatively space-consuming, since numerous voids remain between the shutter and the tube when the shutter is entirely rolled up on the tube, the loss generated by these voids being multiplied by the number of turns of the flap around the tube. We shift the first round of winding outwards so we penalize the total winding.
  • FR-2 821 113-A1 describes a plastic lock fixed in a groove formed on a roller shutter drum. Assembly requires the use of a tool.
  • DE-202019102890 describes a lock, comprising a front link, made of plastic material and mounted on a projecting portion of a winding tube, and a locking clip, made of metal, to secure the link to the tube.
  • the invention more particularly intends to remedy by proposing a new system, in which the lock can be mounted on the tube and removed from the tube without any specific tool, and which does not waste space when the shutter is rolled up on the tube.
  • the invention relates to a system comprising a winding tube for a rolling shutter apron and a connecting lock between the tube and the apron according to claim 1.
  • the fixing of the front link on the tube is secured by hooking and blocking members, the blocking member being configured to be manipulated by hand and not requiring the use of any specific tool. during assembly or disassembly.
  • the longitudinal mounting position of the lock along the tube can be chosen freely when the attachment members are facing the lights.
  • the lock can be mounted on the tube independently of the direction of rotation of the tube.
  • the fixing groove has a reduced angular size, which favors the compactness of the lock-tube system.
  • the front link is housed in a groove made hollow on the surface of the tube, and the external radial surface of the front link is flush with the envelope of the outline of the tube, which does not waste space when the apron is wrapped around the tube.
  • the invention also relates to a roller shutter installation, the installation comprising an apron and such a system.
  • the installation 2 comprises a box 4, in which is housed a roller shutter system 6.
  • System 6 includes a tube 8 and a lock 10.
  • Chest 4 shown skinned on the figure 1 , is arranged horizontally above an opening drilled in a wall.
  • the wall and the opening are not represented, the opening being able to be for example a window or a French window.
  • the tube 8 defines a longitudinal axis A8.
  • the tube 8 is arranged horizontally in the box 4 and is pivotally mounted with respect to the box 4 around the longitudinal axis A8, by means of connecting members, not shown.
  • these connecting members can be fixed to elements of the trunk or even fixed to the wall.
  • the lock 10 comprises at least one front link 12 and a rear link 14.
  • the lock 10 also comprises an intermediate link 16.
  • the intermediate link 16 is pivotally mounted with respect to the front and rear links 12 and 14, according to respective axes of rotation A12 and A14, which are parallel to each other. The lock 10 is thus hinged.
  • the front link 12 is fixed to the tube 8, the detail of the connection between the front link 12 and the tube 8 being explained below.
  • Installation 2 further comprises a flap apron T.

  • the upper blade 20 is linked to the rear link 14 of the lock 10, while the lower blade 22 is free in vertical translation.
  • the rear link 14, linked to the apron T is thus sometimes called “apron link", while the front link 12, linked to the tube 8, is sometimes called "tube link”.
  • the "inside” and “outside” directions are directions that are taken with respect to an assembled configuration of the lock 10 on the tube 8 and which must be interpreted with respect to the tube 8.
  • the installation 2 further comprises two slides 24, which are arranged vertically under the box 4 facing each other and together define a guide plane P26 of the apron T.
  • the apron T is deployed in the guide plane P26, partially concealing the opening in the wall.
  • the tube 8 comprises drive members, not shown, configured to move the tube 8 in rotation around the longitudinal axis A8.
  • the drive means can be manual, such as a winch, or electrically controlled.
  • the rotation of the tube 8 in one direction causes the winding of the lock 10 and the apron T around the tube 8, in a rolled-up configuration of the roller shutter.

  • the lugs 56 or 256 are three in number. In a variant not shown, the number of lugs may be different from three. Whatever the number of lugs 56 or 256, it is understood that the lugs 56 or 256 must be arranged on the rear face 56 of the link 12 so as to cooperate with the slots 40, which are regularly distributed along the length of the groove. 30, that is to say that the lugs 56 or 256 must be spaced apart longitudinally with respect to the axis A8 by a length equal to a multiple of the pitch L40 or L240 between two adjacent lights 40 or 240.
  • the two rows of slots 40 or 240 are offset from each other, along the axis A8.
  • the two rows of lights 40 or 240 can be arranged in staggered relative to each other, on either side of the plane P8.
  • the arrangement of the attachment members and of the lugs of the lock is then adapted accordingly. It is understood that as long as a lock, comprising attachment members such as the lugs 56 or 256 and locking members such as the locking members 58 or 258, is configured to cooperate with the two rows of lights 40 or 240 offset, this lock can be mounted on the tube 8 in several longitudinal positions of the lock relative to the tube 8. Such a lock can also be mounted on the tube 8 independently of the direction of rotation of the tube 8.
  • the installation 2 is a rolling shutter installation, the apron T being composed of rigid blades 18 articulated.
  • the apron T can be replaced by a flexible fabric, such as a solar protection fabric or a mosquito net.
  • the groove 30 comprises a bump 38, which separates the bottom 32 into two parts, which are symmetrical with respect to the plane P8 and which are geometrically carried by the same cylinder portion centered on the longitudinal axis A8 and of radius R32.
  • the bump 38 contributes to the rigidity of the tube 8 but is however not essential to the proper functioning of the invention.
  • the bump 38 is omitted, and the bottom 32 of the groove 30 is in a single part, geometrically carried by a cylinder portion centered on the longitudinal axis A8 and of radius R32.
