Definitions

  • the invention relates to a device for driving a roller shutter, the deck of which moves at a slight inclination and comprising a shaft for winding and / or unwinding the deck formed by blades provided at each of their lateral ends with means of gripping 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 side flanges of a box on which abut guide rails in which the lateral ends of the deck blades slide.
  • EP-A-0 145 628 already discloses a device for driving a rolling shutter for glass verandah roofs, roof skylights 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 whose teeth 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 depending on 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 apron 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 whose deck is formed from thin double-walled blades or from single-walled blades.
  • the nipples of grip include 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 disengagement of the latter with respect to to 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 apron and would lose the advantage of using thin double-walled blades or single-walled blades .
  • the present invention aims to remedy these drawbacks and proposes to provide a device for driving an apron of a roller shutter consisting of thin double-walled blades or single-walled blades.
  • the invention solves the problem of creating a device for driving a rolling shutter whose deck moves at a slight inclination and comprising a winding shaft and / or unwinding of the apron formed of blades provided at each of their lateral ends with 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 by relative to the winding and / or unwinding shaft, these shafts being held by lateral flanges of a box on which abut guide rails in which the lateral ends of the deck slats slide, the gripping means of which are lights made at the lateral ends of the thin double-walled blades or single-walled blades from which the apron is formed and provided with reinforcements having at least one lumen, located in line with the lumen of the blades and cooperating with the teeth of the cam wheels of the second drive shaft.
  • the advantages obtained thanks to this invention consist essentially in the fact that it is possible to use for the production of the apron thin double-walled blades or single-walled blades and, therefore, reduce the winding diameter of said apron .
  • By reducing this winding diameter it is possible to reduce the section of the box and to provide, in particular, the roof windows with a shutter without spoiling the aesthetics of these roof windows.
  • the formation of snowdrifts is reduced at the upper part of the roof window provided with a box of reduced height.
  • FIG. 1 shows, in perspective view, one of the lateral ends of the upper end of a rolling shutter comprising the drive device according to the invention.
  • FIG. 2 represents an exploded view of the end of a thin double-walled blade and of a reinforcement constituted by an insert.
  • Figure 3 shows, in elevation view, the cooperation of the thin double-walled blade provided with the insert with the cam wheel.
  • Figure 4 shows, in exploded view, the end of a single-walled blade and a reinforcement constituted by a jumper spanning the lateral edge of the blade.
  • FIG. 5 shows, in elevation view, the cooperation of the single-walled blade provided with the jumper with the cam wheel of the drive shaft.
  • the roller shutter 1 intended to equip the roofs of verandas, the roof dormers and the like and, in general, the openings having a low inclination or a zero inclination such as the top of private swimming pools, comprises a deck 2, made up of thin double-walled blades 3 (see Figure 2) or single-walled blades 4 (see Figure 4).
  • This apron 2 is wound or unwound from a winding and / or unwinding shaft 5 and it is actuated by a second drive shaft 6 disposed downstream relative to the winding shaft and / or unwinding 5.
  • These shafts 5, 6 are held by lateral flanges 7 of a box (not shown) on which abut guide rails 8 in which the lateral ends 9, 10 of the blades 3 or 4 slide.
  • the second drive shaft 6 comprises, at each of its ends 11, a cam wheel 12 cooperating with gripping means 13 with which the blades 3 or 4 are provided.
  • the gripping means 13 are constituted by slots 14 passing right through the back 15 of the blades 3 or 4. These slots 14 are arranged at the lateral ends 9, 10 of the blades 3 or 4. In these lights 14 engage the teeth 16, 17 of the cam wheels 12.
  • these reinforcements are an insert 20 which is threaded into the lateral edge 21 of the thin double-walled blade 3.
  • the front edge 22 and the rear edge 23 of this insert 20 abut against the front wall 24 and rear wall 25 of the blade 3.
  • Said insert 20 also includes a lumen 26 located, after positioning of the latter in the blade 3, in the same plane as the lumen 14 of the blade 3.
  • This light 26 has a protruding peripheral edge 27 matching the edges 28, 29, 30, 31 both lights 14 tant and lights 142 produced respectively in the inner wall 32 and the outer wall 33 of the back 15 of the blade 3.
  • the height 34 of this projecting peripheral rim 27 is equal to or slightly less than the thickness 35 of the blade 3 so that this peripheral rim 27 does not projection relative to the external face 36, 37 of the internal 32 and external 33 walls of the back 15 of the blade 3.
  • the insertion of this insert 20 is by clipping, this clipping being possible due to the elasticity of the walls internal 32 and external 33 due to the small thickness of the latter.
  • these reinforcements are a jumper 38 spanning the lateral edge 39 of the single-walled blade 4, so that the two parallel wings 40, 41 of this jumper 38 come to bear against the internal face 42 and outer 43 of the blade 4.
  • These two parallel wings 40, 41 have slots 44, 45 which, after assembly, are located in the same plane as the slot 14 of the blade 4.
  • the slots 44, 45 are provided with a peripheral edge projecting inwards 46, 47 snapping into the lumen 14 of the blade 4.
  • the sum of the heights of these peripheral edges 46, 47 is slightly less than the thickness of the wall of the blade 4.
  • Said jumper 38 is made integral with the blade 4 by snap-fastening of the peripheral edges 46, 47 in the lumen 14 of the blade 4.
  • the jumper 38 is made of an elastic material forming a spring ensuring the elastic approximation of the parallel wings 40, 41 after their spacing necessary for the installation of the jumper 38.
  • the use of the latter does not in any way increase the apron winding diameter because the sum of the thicknesses of the rider 38 and the single-walled blade 4 is not greater than the thickness of two to three millimeters of the thin blade 3.
