Definitions

  • the invention relates to a shutter comprising an apron consisting of a juxtaposition of blades at least hinged together and designed to deploy, to extend in lateral guide channels, from a winding tube through a mechanism adapted driving, said shutter further comprising a self-locking device of said apron in the deployed position.
  • the present invention relates more particularly to the field of roller shutters.
  • such a shutter comprises, in the usual manner, an apron consisting of a juxtaposition of blades at least articulated to each other so as to allow its folding on a winding tube actuated in rotation by means of a suitable manual or motorized drive mechanism.
  • this winding tube including said drive mechanism takes position in a box in which laterally extend slides in which are moved side ends of said blades during deployment of the deck.
  • Such a shutter also comprises, in the usual manner, a self-locking device of the deck in the deployed position whose function is to prevent it from being able to go up in the caisson under the influence of a thrust applied to it directly, for example, during an attempted break-in.
  • such self-locking devices consist of one, two or more links connecting the first blade of the apron to the winding tube and which have the ability, on the one hand, to come himself fold around the latter so as not to hinder the winding of said apron inside the box and, on the other hand, to bend between this winding shaft and said first deck blade when it is in fully deployed position.
  • this type of self-locking device is effective only when it is in a specific position that should be mastered perfectly.
  • the size and the number of links constituting the self-locking device must be strictly determined with respect to the aforementioned distance.
  • the links corresponding to such self-locking devices are very often at the origin of a larger section of the rolling shutter apron wound around the winding tube.
  • Such blades which are defined capable of exerting a thrust on the apron to activate the locking device may, in the initial phase of the folding of the deck, interfere with the normal winding of its first turns around the winding tube, so that the section of this wrapped apron may be, in some cases, larger than necessary. Taking into account this risk, it is essential to size the casing of the roller shutter intended to house this deck in wound position.
  • the effectiveness of the locking device is dependent on the fatigue of the elastic blades over time.
  • this stiffness may be insufficient to push back the apron with its attachment profile in cooperation with the docking elements which is provided the front wall of said box.
  • the present invention attempts to remedy the aforementioned problems through a solution using the kinematic operation of a roller shutter to ensure naturally the blocking of the deck in fully deployed position.
  • the invention relates to a roller shutter comprising an apron consisting of a juxtaposition of blades at least hinged together and designed to deploy, to extend in lateral guide slides, since a winding tube through a suitable drive mechanism, said shutter further comprising a self-locking device of said apron in the deployed position, characterized in that it comprises connecting means connecting the first plate of the deck to the tube d winding adapted adapted, after complete unwinding of said apron, to cause the tilting of at least said first blade of said apron within said lateral guide slide, to bring hooking means equipping said apron to cooperate with means of docking formed in said lateral slide.
  • Said connecting means are conceived suitable, during the control of the winding rotation of the latter, to exert on said apron a traction according to a first resultant, in the plane of the deck, and, during the control in rotation of unwinding of the winding tube, after total deployment of said deck and under the impulse of a complementary rotation, to exert on this deck a traction according to a resultant second component perpendicular to the plane of the deck in a second direction opposite to the first, this second resultant being divergent with respect to the first to repel, in the direction of docking means, the attachment means associated with said apron, the side corresponding to said second direction, said docking means and the fastening means constituting, substantially said blocking device.
  • said connecting means are adapted, during the control of the winding rotation of the latter, to exert on said apron a traction according to a first resultant component perpendicular to the plane of said apron in a first direction and during the rotational control of unwinding of the winding tube, after total deployment of said apron and under the impulse of a complementary rotation, to exert on said apron a traction according to a resultant second component perpendicular to the plane of said apron, in a second direction, opposite the first, this second result being divergent with respect to the first to repel, in the direction of docking means, the attachment means associated with said apron, the side corresponding to said second direction, said docking means and said means of docking; fastening component, substantially said self-locking device.
  • the docking means are formed in the lateral guide slides.
  • the present invention relates to the field of shutters.
  • Such a shutter 1 comprises an apron 2 consisting of a juxtaposition of blades 3, 4 at least hinged together and designed to deploy to extend in lateral guide slides 5, from a tube of winding 6.
  • such a shutter 1 prefferably be provided with a device 8 for self-locking said apron 2 in the deployed position.
  • a self-locking device has the function of preventing, once the shutter 1 closed, that it is possible, in the context of an attempted break-in, to push the apron 2 into the box 7.
  • the shutter 1 comprises connecting means 9 connecting the first blade 3 of the deck 2 to the winding tube 6.
  • These connecting means 9 are particularly designed for, when one controlling in rotation said winding tube 6 in the winding direction of the deck 2, direction identified by the arrow F1, it is exerted on the deck 2 a traction according to a first resultant R1, as the case may be, in the plane P of the apron 2 or perpendicular component C1, in a first direction D1, corresponding, in the drawings, to that going to the inner side I.
  • connection means 9 are furthermore designed, when the winding tube 6 is rotated in the direction of the unfolding F2 of the deck 2, after total deployment of the latter and under the pulse of a complementary rotation, which has been marked Rc in FIG. 3, to exert on this deck 2 a traction according to a second resultant R2 which, respectively to the first resultant R1, has a perpendicular component C2 in a second direction D2, opposite the first D1.
  • this second resultant R2 is necessarily divergent with respect to the first R1 and is defined to push, in the direction of docking means 10, hooking means 11 associated with said apron 2, this to ensure a locking of the latter. in the deployed position.
  • these attachment means 10 and the attachment means 11 define, substantially, the self-locking device 8 of the shutter 1.
  • said docking means 10 are formed in at least one of the lateral wings 5.
  • the docking means 10 are more particularly in the form of a scale 14 fitted internally to said lateral slide 5 , the wall 12 located on the opposite side to the first direction D1, that is to say in the second direction D2.
  • This ladder 14 is more particularly formed in the end portion 15 of the lateral slide 5 abutting the box 7.
  • hooking means 11 in the form of hooks 16, they equip the deck 2, at its end 17 corresponding to the first blade 3, more particularly at the side edge moving in the lateral slides 5, which is on the side 18 next to the docking means 10.
  • hook-shaped elements 16 defined to form redan in cooperation with the scale 14, can directly equip the first blade 3 of said apron 2 or a joining profile 19 through which the connecting means 9 cooperate with said first blade 3 In fact, these hook-shaped elements 16 may be further provided at said connecting means 9.
  • these are in the form of flexible fasteners 20, one end of which is secured to the winding tube 6 and whose opposite end cooperates directly or through the aforementioned connecting section 19 with the first blade 3 of the apron 2.
  • the plane P in which the apron 2 deploys crosses the section of the winding tube 6.
  • the winding tube 6 is not located exclusively, a either side of this plane P of the deck 2 so that in the final phase of deployment of the deck 2 and under the effect of the complementary rotation RC of the winding tube 6 in the direction of unwinding, the attachment point 21 of the connecting means 9 on the winding tube 6 passes from one side I of the opposite side E to said plane P.
  • means of docking may constitute hooking means and vice versa.
  • the solution according to the invention avoids the use of more complex self-locking devices as known in the state of the art.
  • the connecting means connecting the apron 2 to the winding tube 6 can be defined by simple straps. If such straps posed, until then, the risk of a winding in an incorrect direction of the apron 2 around the winding tube 6, this risk is not incurred through the solution according to the invention.
  • the present invention not only addresses a self-locking problem of an apron in the deployed position, but, in addition, to that of the complexity of the currently existing systems.
