Definitions

  • the invention relates to a device for driving a rolling shutter, the apron of which moves at a slight inclination and comprising a shaft for winding and / or unwinding the apron formed from thin blades provided at each of their lateral ends with means.
  • gripping formed by lights made in said lateral ends and provided with reinforcement consisting of an insert inserted laterally into the edge of the thin blade and also having a light located in line with the lights of the thin blades, these gripping means cooperating with cam wheels having an idle stroke between each tooth and placed at each of the lateral ends of a second drive shaft disposed downstream relative to the winding and / or unwinding shaft, these shafts being held by lateral flanges of a box on which abut the guide rails in which the lateral ends of the blades slide s fine apron.
  • the various blades of the deck are connected together by telescopic joints to, on the one hand, ensure a certain rotation of a blade relative to its neighbor to allow winding (or unwinding of the deck) on (de ) the winding and / or unwinding shaft and, on the other hand, facilitate a certain displacement of the blades relative to their longitudinal axis to free the days made in the head of the blade.
  • the latter has a folded lip in the form of a hook which is threaded laterally into the heel of the next blade, this heel having a gutter open downwards and integral with the front wall of the thin blade and a hook oriented towards the internal space of the gutter and integral with the rear wall of the thin blade.
  • document EP-A-0.145.628 discloses a device for driving a rolling shutter for glass verandah roofs, roof dormers and the like whose deck moves at a slight inclination.
  • This device comprises a winding and / or unwinding shaft for said deck.
  • the latter is formed of blades threaded laterally and connected together by a joint.
  • Each blade is provided, at each of its ends, with gripping means constituted by a single stud projecting from the lateral edges of the blades.
  • These gripping means cooperate with cam wheels, the teeth of which have flanks consisting of an involute of a circle.
  • These cam wheels have, between each tooth, an idle stroke to absorb the variation in the distance between two consecutive pins according to the movement of the deck.
  • cam wheels are arranged at each end of a second drive shaft and are integral in rotation with the latter, this second drive shaft being arranged downstream relative to the winding shaft and / or unfolding.
  • These shafts are held in place by lateral flanges of a box in which the deck is rolled up and unrolled, the lateral ends of the blades of which slide in guide rails integral with the box.
  • this known device has a certain number of drawbacks, in particular it cannot be used for roller shutters the deck of which is formed from thin blades or single-walled blades. Indeed, it is necessary that the gripping pins have a resistance greater than the torque of the electric motor actuating the drive shaft to transmit any blocking of the apron to the cam wheels and, consequently. to the drive shaft to cause the latter to disengage from the electric motor. This resistance can only be obtained by giving the nipples a relatively large diameter which would automatically increase the winding diameter of the deck and would lose the advantage of using thin blades.
  • the object of the present invention is to remedy these drawbacks and proposes to provide a device for driving an apron of a roller shutter made up of thin blades whose movement of a thin blade relative to its neighbor is condemned.
  • the invention as characterized in the claims solves the problem of creating a drive device for a roller shutter, the deck of which moves at a slight inclination and comprising a winding and / or unwinding shaft.
  • apron formed of thin blades provided at each of their lateral ends with gripping means formed by the openings made in said lateral ends and provided with reinforcement consisting of an insert inserted laterally into the edge of the thin blade and also having a light located at the right of the lights of the thin blades, these gripping means cooperating with cam wheels having an idle stroke between each tooth and placed at each of the lateral ends of a second drive shaft disposed downstream relative to the shaft d winding and / or unwinding, these shafts being held by lateral flanges of a box on which abut the guide rails in which the lateral ends of the thin blades of the deck slide, the insert of which, on the side of its edge directed towards the heel of the thin blade, means engaging in the gutter of said thin blade and condemning any movement of the thin blade
  • the roller shutter 1 comprises an apron 2 moving at a slight inclination and winding or unwinding from a winding and / or unwinding shaft 3.
  • This apron 2 consists of thin blades 4, 5, 6 connected between them by telescopic joints 7, 8, 9. These thin blades 4, 5, 6 are formed of a front wall 10 and a rear wall 11. The front walls 10 and rear 11 are connected together by a head 12 comprising a lip 13 folded in the form of a hook.
  • the thin blade 4, 5, 6 has a heel 15.
  • This heel 15 has a gutter 16 open downward and integral with the front wall 10 and a hook 17 oriented towards the internal space 18 of the gutter 16 and secured to the rear wall 11 of the thin blade 4, 5, 6.
  • the head 12 of the downstream thin blade 6 is laterally threaded into the heel 15 of the upstream thin blade 5, so that the active face 19 of the lip 13 of the downstream thin blade 6 clings to the active face 20 of the hook 17 of the heel 15 of the thin blade upstream 5.
  • the connection between the two thin blades 5, 6, constitutes the articulation 7, 8, 9 allowing one of the blades thin 5 to pivot relative to the neighboring thin blade 6 to allow winding of the deck 2 on the winding and / or unwinding shaft 3.
  • the telescopic stroke of the joints 7, 8, 9 is a function of the height 21 of the head 12 and of the depth 22 of the gutter 16.
  • Each thin blade 4, 5, 6, is provided at each of its lateral ends 23, 24, 25 with gripping means constituted by slots 26, 27, 28 produced in said lateral ends 23, 24, 25 and passing right through hand, the thin blade 4, 5, 6. Because of their low thickness, reinforcements formed from inserts 29, 30, 31 are introduced laterally into the fine blades 4, 5, 6. In these inserts 29, 30, 31 are made slots 32, 33, 34 which, after installation of these inserts 29, 30, 31 in the thin blades 4, 5, 6, are in the same alignment as the slots 26, 27, 28 of the latter.
  • the upper edge 35 of the inserts 29, 30, 31 abuts against the head 12 while the lower edge 36 abuts against the bottom 37 of the gutter 16.
  • the slots 26, 27, 28 and 32, 33, 34 cooperate with teeth 38, 39 of a cam wheel 40 placed at each of the ends 41 of a drive shaft 42 disposed downstream relative to the shaft winding and / or unwinding 3.
  • This drive shaft 42 exerts a thrust on the deck 2 for the deployment of the latter.
  • winding and / or unwinding shaft 3 and the drive shaft 42 are held by lateral flanges 43 of a box 44 on which abut guide rails 45 in which the lateral ends 23, 24 slide, 25 thin blades 4, 5, 6.
  • the inserts 29, 30, 31 are provided with means 46 condemning any movement of the thin blades 4, 5, 6 relative to their longitudinal axis 47.
  • These means 46 are located on the side of the bottom edge 36 of the inserts 29, 30, 31 and come to engage in the gutter 16, therefore said means 46 are located on the side of the heel 15 of the thin blades 4, 5, 6.
  • these means 46 are a rod of which one of the ends 48 is integral with the edge lateral lateral 49 of the insert 29, 30, 31.
  • This rod 46 has a longitudinal axis 50 parallel to the longitudinal axis 47 of the thin blades 4, 5, 6.
  • the free end 51 of this rod 46 is located on the side of the center line of the deck 2.
  • the inserts 29, 30, 31 are molded plastic parts and the rods 46 form a block with the bodies 52 of said inserts 29, 30, 31.
  • the external lateral edge 49 has an extension in which is inserted one of the ends of an attached rod which may be a metal rod.
  • the length 53 of the rod 46 is equal to the length 54 of the inserts 29, 30, 31.
  • the length 53 of the rod 46 is greater than the length 54 of the inserts 29, 30, 31.
