Definitions

  • the present invention relates to a roller shutter system comprising a winding tube and a latch.
  • the invention also relates to a rolling shutter installation comprising such a system.
  • Roller shutters are used at building openings, such as windows, for example. They are mainly used to regulate 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 shutter winding tube is placed in this box.
  • the invention relates more particularly to the mechanical connection between the shutter curtain and the roller shutter winding tube.
  • roller shutters are relatively vulnerable to burglary attempts. With basic models, burglars usually just need to run a hand or a thin tool under the last blade to lift the roller shutter and access 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 raising the apron from the fully lowered position, by an external action, such as an attempted break-in for example, other than a normal action on the operating device, by means of 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 on a roller shutter is to use fixing members 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 longitudinal groove formed in projection, the front link having on an internal face a shape adapted to fit, by elastic deformation of the front link, the front link on the tube groove.
  • the front link comprises locking lugs mounted opposite each other, these lugs cooperating with openings made in the radial surfaces of the groove.
  • this system requires significant force during assembly, as well as during disassembly, requiring the use of a tool, such as a screwdriver, to pry the wall of the tube and remove the front link.
  • a tool such as a screwdriver
  • such a system mounted protruding on the tube is relatively space-consuming, since many voids remain between the shutter and the tube when the shutter is fully wound on the tube, the loss generated by these voids being multiplied by the number of turns of the shutter around the tube. We shift the first winding turn towards the outside 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. The assembly requires the use of a tool.
  • 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 wound on the tube.
  • the invention relates to a system comprising a tube for winding a roller shutter curtain and a connecting bolt between the tube and the curtain.
  • the tube defines a longitudinal axis and has an outline with a casing and an attachment groove.
  • the groove is recessed relative to the casing of the tube and comprises a bottom, a front wall and a rear wall.
  • the latch has at least two articulated links, of which a rear link is configured to attach to an upper blade of the shutter and a front link is configured to be secured to an outer radial surface of the tube.
  • the front link has an internal surface, an external surface opposite the internal surface, a front face and a rear face opposite the front face, the internal surface having a profile complementary to that of the fixing groove.
  • slots are formed in the tube fixing groove.
  • the front link comprises hooking members and at least one locking member, some of the slots being located opposite each of the hooking members and another slot being located opposite the locking member.
  • the locking member is configured to be handled without tools between a locking position, in which the locking member cooperates with the slot located opposite so as to retain the front link in the groove, and a dismantling position, in which the locking member does not retain the front link in the fixing groove.
  • the fixing of the front link on the tube is secured by hooking and locking members, the locking member being configured to be handled by hand and not requiring the use of any specific tool during assembly or disassembly.
  • the longitudinal position for mounting the lock along the tube can be chosen freely when the hooking members are facing the lights.
  • the lock can be mounted on the tube regardless 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 formed recessed on the surface of the tube, and the outer radial surface of the front link is flush with the envelope of the contour 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 accommodated a roller shutter system 6.
  • System 6 includes tube 8 and lock 10.

  • the blades 8 are movable in rotation with respect to each other around axes of rotation parallel to the longitudinal axis A8.
  • 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 directions “inside” and “outside” are directions which are taken with respect to an assembled configuration of the latch 10 on the tube 8 and which must be interpreted with respect to the tube 8.

  • several locking members 58 or 258, each comprising a bolt provided on a rib 62 or 262, can be provided on the front link 12.
  • the lock 10 comprises several bolts of the type of bolts 60 or 260
  • the bolts must be spaced apart from each other longitudinally with respect to the axis A8 by a length equal to a multiple of the pitch L40 or L240 between two contiguous slots 40 or 240, in order to cooperate with the slots 40 or 240 located opposite the slots 40 or 240 cooperating with the pins 56 or 256.
  • the hooking members which are in the examples described the lugs 56 or 256, are designed to withstand the forces generated during the use of the roller shutter, in particular the tensile forces when the apron is fully unwound in the guide plane. P26 and winding begins.
  • the pins 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 pins 56 or 256, it is understood that the pins 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 from each other longitudinally with respect to the axis A8 by a length equal to a multiple of the pitch L40 or L240 between two contiguous slots 40 or 240.
  • the two rows of slots 40 or 240 are offset with respect to each other, along axis A8.
  • the two rows of lights 40 or 240 can be arranged staggered with respect to each other, on either side of plane P8.
  • the arrangement of the hooking members and the lugs of the lock is then adapted accordingly. It is understood that as long as a lock, comprising hooking 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 slots 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 regardless 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 canvas, such as a sun protection canvas 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 portion of the cylinder centered on the longitudinal axis. A8 and radius R32.
  • the bump 38 contributes to the rigidity of the tube 8 but is however not essential for 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 portion of a cylinder centered on the longitudinal axis A8 and of radius R32.
