Definitions

  • the invention relates to a device for driving a rolling shutter, the deck of which moves at a slight inclination and comprising a shaft for winding and / or unwinding the deck formed from thin double-walled blades provided at each of their ends.
  • lateral of gripping means formed by slots made in said lateral ends and provided with reinforcements constituted by an insert inserted laterally into the edge of the thin double-walled blade and also having a lumen situated in line with the lumens of the thin double-walled blades wall, 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 shaft and / or unwinding, these shafts being held by lateral flanges of a box on which abut the guide rails in which They slide the lateral ends of the thin double-walled slats of the deck.
  • EP-A-0317461 already discloses a device for driving a roller shutter corresponding to the preamble of claim 1.
  • 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 hook-shaped folded lip 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 double-walled blade and an oriented hook towards the internal space of the gutter and integral with the rear wall of the thin double-walled blade.
  • document EP-A-0145628 discloses a device for driving a rolling shutter for glass verandah roofs, roof dormers and the like, the deck of which 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 whose teeth have flanks made up 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 by lateral flanges of a box in which the apron is wound and from which the deck takes place, 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 whose deck is formed from thin double-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 deck to the cam wheels and, consequently, to the shaft of drive 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 double-walled blades.
  • the object of the present invention is to remedy these drawbacks and proposes to provide a device for driving a roller shutter curtain made up of thin double-walled blades, the displacement of a thin double-walled 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 double-walled blades provided at each of their lateral ends with gripping means formed by the openings made in said lateral ends and provided with reinforcements constituted by an insert inserted laterally into the edge of the thin double-walled blade and also having a lumen located in line with the lumens of the thin double-walled blades, these gripping means cooperating with cam wheels having a vacuum course between each tooth and placed at each of the lateral ends of a second drive shaft disposed downstream with respect to the winding and / or unwinding shaft, these shafts being held pa r side flanges of a box on which abut the guide rails in which the lateral ends of the thin double-walled blades of the apron slide, the insert of which, on the side of its edge directed towards the heel
  • FIG. 1 represents a perspective view of one of the lateral ends of the upper end of a rolling shutter comprising an apron formed from thin double-walled blades provided with an insert in accordance with the invention.
  • Figure 2 shows an elevational view of an apron according to the invention.
  • FIG. 3 represents an exploded view of the end of a thin double-walled blade and of an insert according to the invention.
  • 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 double-walled blades 4, 5, 6 interconnected by telescopic joints 7, 8, 9. These thin double-walled blades 4, 5, 6 are formed by a front wall 10 and a rear wall 11. The front walls 10 and rear 11 are connected between them by a head 12 comprising a lip 13 folded in the form of a hook.
  • the thin double-walled 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 integral with the rear wall 11 of the thin double-walled blade 4, 5, 6.
  • the head 12 of the thin downstream double-walled blade 6 is laterally threaded into the heel 15 of the upstream double-walled thin blade 5, so that the active face 19 of the lip 13 of the thin double-walled blade downstream 6 is hooked to the active face 20 of the hook 17 of the heel 15 of the double-walled thin blade 5, 6, constitutes the articulation 7, 8, 9 allowing one of the thin double-walled blades 5 to pivot relative to the neighboring thin double-walled blade 6 to allow winding of the deck 2 on the winding and / or unwinding shaft 3.
  • the telescopic travel of the articulation 7, 8, 9 is a function of the height 21 of the head 12 and the depth 22 of the gutter 16.
  • Each thin double-walled 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 through right through, the thin double-walled blade 4, 5, 6. Because of their small thickness, reinforcement formed by inserts 29, 30, 31 is introduced laterally into the thin double-walled blades 4, 5, 6 In these inserts 29, 30, 31 are made of the lights 32, 33, 34 which, after placement of these inserts 29, 30, 31 in the thin double-walled blades 4, 5, 6, are in the same alignment as the lights 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 double-walled blades 4, 5, 6.
  • the inserts 29, 30, 31 are provided with means 46 preventing any movement of the thin double-walled 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 thin double-walled blades 4, 5, 6.
  • these means 46 are a rod, one of the ends 48 of which is integral with the external lateral edge 49 of the insert 29, 30, 31.
  • This rod 46 has a longitudinal axis 50 parallel to the longitudinal axis 47 thin double-walled blades 4, 5, 6.
  • the free end 51 of this rod 46 is located on the side of the median axis of the deck 2.
