Definitions

  • the invention relates to a device for self-locking an apron.
  • rolling shutter in the deployed position consisting of at least two links linked by means of articulation, one of these links being pivotally mounted on a winding shaft of the apron between a folded position around this tree and a deployed position, the other link being connected, by articulated connection means, to the first blade of the deck.
  • the present invention will find its application in the field roller shutters.
  • the height of the blades extending in the box when the apron is deployed influences the position that borrows the self-locking device when entering action.
  • the constraints printed on the first blade of the apron are different.
  • the ideal case corresponds to the situation where the constraint printed by the self-locking device on the first blade of the deck is located, exactly, in the plan of the latter, assuming that this first blade of the apron is, itself, in alignment with the other blades.
  • Gold since this first blade of the deck is located the most often either too high or too low relative to the position ideal of the self-locking device, the constraint imparted by the latter on this first blade is very often translated by a component perpendicular to the plane of the deck so that this first blade is either pushed against the wall of the box, either folded in the direction of the winding shaft under this constraint. This has the consequence of soliciting, strongly, the means of articulation connecting this first blade to the second until causing, in some cases, their rupture.
  • the document FR-A-2.720.100 describes, already, a device locking device composed of several links, the first of which is pivotally mounted on the deck winding shaft by by means of hooking means with adjustable position. More precisely, these attachment means are presented under form of flanges with partially extending flanges around the winding shaft and presenting a series of housing for receiving a pin on which is pivotally mounted the first link of the device self-locking.
  • such a device is able to perform these functions in a way optimal, not in a single scenario as for the feature of the document cited above, but in two cases specific.
  • such a self-locking device cannot respond to all situations encountered. So, except in two ideal situations, the action of this device of self-locking on the first blade of the deck does not take place in alignment with the latter, leading to a setting under stress of the final blade and, therefore, of its means of articulation connecting it to the next blade, even to the last link of the self-locking device.
  • the invention relates to a self-locking device a roller shutter curtain in the deployed position, consisting of at least two links connected using means one of these links being pivotally mounted on an apron winding shaft between a folded position around this tree and a deployed position, the other link being connected, by articulated connecting means, to the first blade of the deck, characterized in that the articulation means connecting the two links of the device are equipped with means capable of ensuring the locking in rotation of the links, one with respect to the other, in any angular position, these means being activated under the impulse of a force tending to repel the link one towards the other.
  • the self-locking device includes elastic return means capable of pushing the first link in its deployed position relative to the shaft winding.
  • the self-locking device can also be provided with three or more links including at least the last, attached to the first blade of the deck, is connected to the previous one using articulation means according to the invention.
  • the advantages of the present invention consist of that as long as the self-locking device is under tension, the last link connected to the first blade of the deck is in able to freely rotate relative to the following links. In this way, this last link of the locking device can be placed ideally in relation to the first blade of the deck regardless of the position of this blade in the box.
  • the feedback provided by the first blade of the apron on the last link tends to push it back in direction of the previous link, which results in to immobilize these links in rotation relative to the other.
  • the action that comes to exert, then, this device self-locking on this first blade of the deck results in a force being exerted, appreciably, in the plane of the latter. As a result, the desired goal is achieved.
  • a rolling shutter 1 comprises a winding shaft 2 an apron 3 composed of a juxtaposition of blades 4, 5, interconnected by means of joints 6 often of telescopic nature to give this deck 3 of the roller shutter 1 an open position and a position total concealment.
  • blades 4, 5 are brought to move, at their lateral ends, in guide rails 7 usually terminating at their ends upper 8 to a box 9 able to house the deck 3 in position wrapped around the winding shaft 2.
  • the first blade 4 of this deck 3 is connected to this winding shaft 2 via a device self-locking device 10 having the function of opposing, under the action of a thrust exerted on said apron 3 completely deployed, when the latter rises inside the box 9.
  • a device self-locking device 10 having the function of opposing, under the action of a thrust exerted on said apron 3 completely deployed, when the latter rises inside the box 9.
  • this self-locking device 10 is consisting of at least two links 11, 12 connected using articulation means 13, one 11 of these links being mounted pivoting on the winding shaft 2, between a position folded around the latter and a deployed position 14, plus particularly visible in Figures 1, 2 and 4.
  • the other link 12 is connected, meanwhile, by connecting means articulated 15 to the first blade 4 of the deck 3.
  • this self-locking device 1 can also be provided with elastic return means 17 capable of repelling the link 11 in its deployed position 14 relative to the shaft winding 2.
  • this free articulation of the links 11, 12, prior to blocking them allows the self-locking device 10 to adjust perfectly to the distance D between the axis 18 of said winding shaft 2 of the free end 19 of the first blade 4 corresponding to the deck 3, specifying that about, that this distance D is dependent on the position taken by this free end 19 of this first blade 4 to inside the box 9.
  • the hinge means 13 have a configuration similar to a toggle joint, link 12 comprising, at its upper end 20, opposite to that intended to cooperate with the first blade 4, a form of hook 21 engaged in a gutter 22 present at the end lower 23 of the next link 11. More precisely, the hook-shaped part 21 has a termination 24 of rounded shape coming to take position in a cradle 25 that defines one of the side walls 26 delimiting the gutter 22. Note that if the hook-shaped part 21 is in able to pivot inside the gutter 22, in particular under the influence of form termination cooperation rounded 24 with the cradle 25, this part in the form of hook 21 has, in addition, a certain clearance 27 inside of this gutter 22 for the reasons which will now be exposed.
  • the rotation locking means 16 are are in the form of attachment means, such as teeth 28, formed at the periphery 29 of the part in the form of hook 21 and intended to cooperate with hooking means complementary such as a dentition of conjugate shape 30, present at the level of the internal wall 31 of the gutter 22.
  • the hooking means in the form of teeth 28, cooperate with the attachment means 30 resulting in the blocking of rotation of the links 11, 12 relative to each other.
  • link 12 may be provided at its upper end 20 with a tab 32 provided, on its side 33 facing the lower end 23 of the link 11, of attachment means, in particular in the form of teeth 28A intended to cooperate with fastening means complementary, also if necessary in the form of teeth 30A, which includes the outer periphery 34 of the wall lateral 26 corresponding to the gutter 22 and defining the cradle 25.
  • the persistent play 27A between the teeth 28A and that 30A when the links 11, 12 are in tension is substantially equal to the clearance 27 between the means attachment 28 and the additional attachment means 30 corresponding, respectively, to the hook-shaped part 21 and the gutter 22.
  • this self-locking device 10 receives means stops 40 capable of limiting the pivot angle of the link 12 relative to link 11, this at least in the direction of winding shaft 2.
  • these stop means 40 are constituted by a stop 41 projecting from the outer periphery 34 of the wall lateral 26 corresponding to the gutter 22 of the link 11, beyond teeth 30A. against this judgment 41 is, therefore, in able to abut the free end of the tab 32 which is fitted with link 12 at its upper end 20. Good heard, we could still imagine other modes of realization of these stop means 40.
  • this first link 11 must have a certain length which, if we imagine it rigid, would somewhat hinder the winding of the deck 3 around this winding shaft 2.
  • this first link 11 can consist of two or more sections of links 11A, 11B which as visible in FIG. 4 are foldable around the winding shaft 2.
  • the links 11, 12 and / or the link sections 11A, 11B may be of curvilinear shape adapted to the section of winding shaft 2.
  • the latter is of polygonal section, to adjust the links 11, 12 or the link sections 11A, 11B in the form sides of this winding shaft 2 of polygonal shape.
  • the self-locking device 10 can consist of more than two links which can all be connected by means of articulation means 13 equipped blocking means 16 knowing, however, that at least the last link 12, attached to the first blade 4 of the deck 3 is connected to the previous link in this way.
