Definitions

  • the invention relates to a flap anti-lift device rolling, making it possible to block said flap when it is deployed in the corresponding opening.
  • roller shutters The major drawback of such types of roller shutters is that they can be easily lifted from the outside, and that therefore they do not offer any guarantee against a possible breaking in.
  • a first type of locking device described in patents CH-A-645,430 and DE-U-9,303,720 include a retainer adapted to extend in the upper extension of a lateral slide, and designed so that when the curtain is raised, the blade upper blocking under this organ thus causing locking in deployed position of said deck.
  • the advantage of such a device is that it is simple design and therefore low cost.
  • the present invention aims to overcome all of the aforementioned drawbacks and aims at an anti-lift device for flaps Rollers with no accessories encroaching on the winding volume apron and can be used with standard size boxes.
  • Another object of the invention is to provide a device anti-lift designed to allow the front apron to settle blocking of the latter.
  • Another object of the invention is to provide a device anti-lift, the settings of which are very easy during installation on site.
  • Another object of the invention is to provide a device anti-lift ensuring possible refocusing of the blades between the outlet of the slides and winding shaft.
  • Another object of the invention is to provide a device anti-lift ensuring the connection between the winding shaft and the upper blade of the apron.
  • each stop blade integral with the upper blade follows a circular path around the winding shaft, then a spiral path (portion of spiral) at the end of unwinding.
  • Each flange stopper follows a circular path in the same radial plane as the corresponding blade stop.
  • each blade stop moves away from the winding shaft following a portion of a spiral and the trajectory of this blade stopper meets the circular trajectory of the flange stopper corresponding so that said stops are caused to brace one against each other by cooperation of their contact faces, first producing a settlement of the deck, then a blocking of the latter in its packed position.
  • the anti-lift device is designed to equip classic roller shutters, without changing the number of slats thereof.
  • each flange stopper and each blade stopper are located on either side of the deck, the winding volume of the latter around the winding shaft is not cluttered with any accessories encroaching on this volume. Therefore, for a given boot volume, we benefits from increased winding capacity.
  • each blade stop which follows a spiral portion trajectory is found at end of a turn against the winding shaft to then adopt a trajectory circular concentric with this tree.
  • This blade stop then escapes the circular trajectory of the flange stop which has a larger diameter.
  • Such a link constitutes a connecting element between the blade stopper and flange stopper which ensures perfect bracing between said stops, at the end of the unwinding, in a locking position frozen because of the triangulated assembly that these three elements form.
  • each link provides a connection between the deck and the winding shaft allowing, if not to remove the attachment means between said aprons and winding shaft, to at least reduce the number of these attachment means.
  • the anti-lift device also comprises advantageously, means for adjusting the radial position of the axis of articulation of each link relative to the associated flange stop.
  • the device anti-lift comprises two flange stops and two blade stops arranged in correspondence on either side of the deck. This is to ensure absolute security since the apron is blocked at its two ends.
  • each blade stop has a front face having a notch in V shape, each flange stop having a front face having a appendage capable of coming to be housed and blocked in said notch.
  • the bottom of the slide and the face opposite the flange stop have suitable transverse ridges to prohibit any movement of said flange stop after blocking.
  • the flange and the face in view of the plate have radial streaks capable of preventing any rotation of said plate after blocking.
  • each stop flange has radial longitudinal edges with an oblique profile so that avoid eccentricity of the blades at the outlet of the guide means.
  • the stops of flange which are positioned on either side of the apron thus play a possible re-centering function of the deck blades once they have emerged guiding means, a function which is further improved by the oblique profile of the longitudinal edges of these stops.
  • the anti-lift device shown mainly in Figures 1, 2, 3 first comprises a flange 11 integral in rotation with the winding shaft 3 and carrying a flange stop 12 adjustable radially.
  • This flange 11 is made up of two elements: first place, a radial annular flange 13 of external diameter greater than that of the winding shaft 3, having a sleeve 14 adapted to adjust on said winding shaft.
  • This flange 13 is pierced with orifices such as 15 evenly distributed.
  • the flange 11 is secured to a plate annular 34 itself secured to the toothed wheel 9 by means of spacers tubular such as 16 extending opposite the orifices 15 of the flange 13 to ensure the locking in rotation of this flange 11 relative to the shaft winding 3.
  • This flange 11 is, moreover, constituted by a flat element oblong 17 adapted to allow angular adjustment of the flange part 13 / sleeve 14.
  • the element 17 has, seen in radial plane, an outline outer substantially ovoid whose surface presents substantially on its two third an annular shape 18 of section adapted to be positioned around of the sleeve 14.
  • This annular portion 18 has, in addition, holes oblongs such as 19 arranged so as to be in correspondence each with an orifice 15 in the flange 13. This arrangement makes it possible to adjust angularly the element 17 relative to the flange 13 / sleeve 14 piece and therefore relative to the flange 11 and the winding shaft 3, then to block it in the desired position by means of any locking system such as screw / nut 20.
  • the faces in view of the flange 13 and the element 17 have radial grooves such as 21 shown in Figure 3.
  • the last third of the surface of element 17 has mainly two spaced radial internal ribs 22, 23 defining a slide 24 extending from the periphery of said element.
  • This slide 24 intended to accommodate the flange stopper 12 has a bottom wall provided with a radial axial light 25, and on both sides of this light, streaks transverse such as 26.
  • the stop 12 associated with the flange 11 has the shape of a rectangular parallelepiped block of dimensions adapted to be able to slide in the slide 24, and of height greater than that of said slide.
  • This stop 12 is pierced with an orifice 27 in correspondence with the light 25 on the slide enabling its radial position to be adjusted by means of any locking system such as screw / nut 28.
  • this stop 12 is provided with transverse ridges 29 in sight, in cooperation with the grooves 26 of the slide 24, to ensure a positive blocking of said stopper the interior of said slide.
  • a peripheral rib 30 ending in the form of a Y 31 whose end of the branch tangent to the external transverse edge of said stop.
  • the longitudinal edges of these ribs 30 have a oblique profile in order to facilitate a possible refocusing of the blades 2 of the deck 1 in backstage 10.
  • the anti-lift device also includes two stops 32 of blades 2 secured to the upper blade 2a, for example according to the classic technique of fitting the blade tips of current decks.
  • stops 32 of blades 2a consist of a strip whose upper part extends substantially above the upper edge of the upper blade 2a.
  • Each strip 32 also has the particularity to present an inclined upper edge forming a notch 33 in the form of V.
  • the anti-lift device comprises, finally, associated with each flange stopper 12 / blade stopper 32 assembly, a link 35 articulated respectively on each of said stops, and adapted to form with these last a triangulated set of which it constitutes the base, at the end of unwinding when these stops are braced against each other.
  • the axis of articulation of this link 35 on the stop flange 12 consists in the example of the screw of the screw / nut assembly 28 extending through an oblong radial lumen 36 formed in said flange stop so as to adjust the radial position of said axis hinge.
  • the link 35 is arranged so as to be arranged in lateral projection relative to the blade upper 2a, so as not to interfere with the winding.
  • FIGS. 4a to 6b represents a shaft end winding 3, it being understood that the opposite end of this end piece is equipped with an identical anti-lift device.
  • the stop 32 of blade 2 is wound around the winding tube 3, that is to say according to a circular trajectory with a diameter smaller than that of the flange stop 12.
