Definitions
- the invention relates to a self-locking device for rolling shutter apron in the deployed position, apron designed adapted to be folded around a winding tube to which it is connected through a first blade through said self locking device.
- the present invention will find application in the field of building closure systems, more particularly that of roller shutters.
- a rolling shutter apron consists of a juxtaposition of blades interconnected in an articulated manner, knowing that these blades are still frequently movable together in a direction perpendicular to their axis, in order to be able to confer audit apron a openwork position.
- these blades reveal openings to height of their articulated connection, promoting the passage of light, as well as the ventilation of the premises.
- the blades are guided, at their lateral ends, by slides in the form of a "U" profile.
- Such a self-locking device is frequently in the form of one, two or more links connected together, but also to the winding tube or to said first blade, by hinge means to pivot axis parallel to said winding tube, this to allow them to fold around the latter when opening the shutter.
- this or these links are pivoted relative to each other, as well as with respect to the winding tube so as to adopt an extended locking position in which they are able to transform the rotation from the latter in a push on the apron.
- the size and the number of links constituting such a self-locking device should be strictly determined with respect to the aforementioned distance.
- the self-locking device is of optimized operation when it comes to print its blocking constraint strictly in the plane of the deck, this through said first blade.
- the number of blades of an apron is thus determined so that in fully deployed position the first of these blades extends inside the box and, therefore above the lateral guide slides, on at least half, or even two-thirds of its height. Since the number of blades can not be precisely adjusted to the exact height of a roller shutter, it may be that to meet the above condition, there is up to one and a half blades remaining at the same time. inside the box when the deck is deployed.
- this or these first apron blades are not systematically aligned with the other blades of the deck, if only because of the distance separating the plane of the latter from the winding tube.
- the self-locking device causes the tilting of the first blade by strongly urging the hinge means connecting it to the blade next, but also to this self-locking device.
- the document EP-0869255 describes a self-locking device that is able to respond to the aforementioned problem.
- the proposed solution consists of a device consisting of two links connected by means of a hinge capable of ensuring the locking in rotation of these links relative to each other in any angular position under the impulse. of a force tending to push them towards each other.
- the self-locking device of this state of the art is capable, regardless of the distance mentioned above, of exerting on the first blade of the apron, a force extending in the plane of the latter, being assumed that said first blade is itself disposed in this plane.
- this solution only partially answers the problem in that it does not allow to ensure the alignment of the first in the plane of the following blades.
- the joint connecting the links can lock in different angular positions. If it is normally able to adapt to the dimensional constraints previously exposed, this blockage of the joint can still intervene unexpectedly, because of the constraints encountered mechanics, such as friction forces, jerky movements, etc.
- this known self-locking device rests on joints with a limited pivot angle, connecting the links between them, to the winding tube and to the first leaf of the apron.
- these joints are strongly solicited, having to retransmit all the efforts of thrust that they are generated by the winding tube or the apron, for example, during an attempted break-in.
- the invention relates to a device for self-locking a rolling shutter apron in the deployed position comprising at least one link connecting, at its ends and through a first and a second articulation, said apron. to a winding tube, characterized in that the first hinge and the second hinge at the ends of the link cooperating respectively with the winding tube and the apron, have a pivot axis substantially perpendicular to the axis of said tube winding.
- the link of the self-locking device is further mounted, at at least one of its ends, slidingly, axially, on the winding tube and / or on the deck of the rolling shutter.
- the self-locking device further comprises elastic means exerting on the link a return force tending to move it from its erased position substantially parallel to the winding tube.
- link or links corresponding to the locking device according to the invention instead of being pivotally mounted on the winding tube about an axis substantially parallel to the latter to, depending on the case, deviate from that and to reach the active blocking position or, on the other hand, to fold around this winding tube, this or these links are pivotable about an axis which is perpendicular to this winding tube for, as the case may be, to fall back along the latter or, on the contrary, deviate from it in the active blocking position, knowing that it can be pushed into the latter under the influence of elastic means.
- this link of the self-locking device allows the latter to adjust to the distance between the plane in which is deployed the apron of the axis of the tube. winding.
- the few blades not yet stacked apron exert a traction force on the link that does not translate into a torque tending to rotate the link around its axes of articulation. Also, this pulling force does not interfere with the elastic return means acting on the link to move it away from the winding tube. Also, very early and under the influence of these elastic return means, this link can push the first blades of the apron in the plane extension of the following blades so that the locking pressure comes to exert in the plane of this deck.
- the link is still connected, at one of its ends, slidably, as the case may be, on the winding tube or apron, in this case the first blade of the latter .
- the link can be designed from two blades articulated together so as to act as a toggle.
- the present invention relates to the field of shutters.
- a self-locking device 1 having the function of maintaining in the deployed position, an apron 2 of roller shutter 3 as shown in FIG. figure 1 this to prevent this deck can be pushed up, for example during an attempted break-in.
- Such an apron 2 roller shutter 3 is usually constituted by a plurality of blades 4 connected by means of articulation means 5 allowing, often, a relative mobility of these blades 4 relative to each other. to others in a direction perpendicular to their longitudinal axis. This feature allows to give the deck 2 a perforated position.
- these blades 4 of the deck 2 are guided, at their lateral end, via slides, usually in the form of "U" profiles. These slides open, at their upper end, in a box 6 housing the winding mechanism 7 of the apron 2 of the shutter 3.
- This mechanism comprises, more particularly, a winding tube 8 to which the apron 2 is connected by means of the self-locking device 1.
- it comprises at least one link 9 connected at one end 10 and through a first hinge 11 to said winding tube 8, while the opposite end 12 of this link 9 cooperates with using a second hinge 13, with the apron 2, in this case, the first blade 14 of the latter.
- this first and second articulation 11; 13 are with a pivot axis 15, 16 substantially perpendicular to the longitudinal axis 17 of the winding tube 8.
- the self-locking device 1 comprises a link 9 in the form of a single blade
- this link 9 may also be constituted by a succession of blades hinged together about axes parallel to pivot axes 15, 16 above.
- the link 9 may comprise two blades hinged together in the manner of a toggle.
- a link 9, in the form of a single blade also preferably comprises at least one of its ends 10, 12, mounted slidingly, axially, as the case may be, on the winding tube 8 or the apron 2, more particularly, the first blade 14 thereof.
- the blades 4 of the apron 2 comprise, at their upper end 19, hooking means of the male type, in the form of a hook, designed adapted to cooperate with fastening means of the female type, in the form of a groove, which is provided with a previous blade at its lower end 20, so as to constitute means of articulation between the blades 5.
- the slider 18 may be provided with fastening means of the female type 21 designed capable of cooperating with the male type fastening means 22 that includes the first blade 14 at its upper end 19.
- the link 9 can be mounted articulated on a fastening support 23 that includes the self-locking device 1, defined support adapted to be attached by screwing, riveting or otherwise on the winding tube 8 .
- this fixing support 23 can be provided with a stop 24 defined to limit the deployment angle of the link 9 by rotation about its pivot axis 15. Through this stop 24, this rotation of the link 9 can be limited so that the angle formed by the latter with respect to said winding tube 8 is, in all cases, less than 90 °.
- the bearing flange 26 carried by the fixing support 23 is designed to cooperate with an attachment slot 27 formed in the link 9, preferably near its cooperating end 12, through the second articulation 13. with the first blade 14 of said apron 2.
- the bearing flange 26 has a tapered end promoting its engagement in the catching light 27 and the centering of the link 9 on the fixing support 23.
- the link 9 is subjected to resilient means 28 tending to push it from its applied position on the attachment support 23, that is to say substantially parallel to the tube of winding 8, in its active locking position, spaced from this winding tube 8.
- this link 9 under the action of these elastic return means 28, is able to push the first blade 14, through which it acts on the deck 2, in the extension plan of the latter. Also, when the self-locking device 1 comes to exert its blocking function through a pressure printed on this first blade 14, it can be certain that this pressure is perfectly applicable in the plane of said apron 2. This allows, finally, to prevent the tilting of the first blade 14 under the effect of this pressure and to strongly urge the joints that connect it to the next blade or to the link 9.
- the self-locking device 1 comprises means 29 for locking in rotation of the link 9 designed to be activated under the impulse of a reactive force of the apron 2 during the blocking of the latter in the deployed position by said self-locking device 1, that is to say under the effect of a pressure exerted by the latter on said apron 2.
- These locking means 29 are still able to be inactivated so as to allow the free rotation of the link 9 under the effect of traction exerted on the latter by the deck 2, therefore during the deployment and folding phases of the latter.
- At least one of these joints 11, 13 is designed in the manner of a yoke 32 having lugs 32A, 32B are mounted on the ends 15A, 15B, articulation pin 15 held by an axle support 33.
- At least one of the holes 34 in the ears 32A, 32B is preferably adjusted with a positive tolerance with respect to the section of the axis 15, from which the above game arises.
- the pivot axis 15, more particularly at least one of its ends 15A, 15B comprise a peripheral toothing 35 with which is designed able to cooperate a tooth portion 36 formed internally to the hole 34 of at least one of the ears 32A, 32B under the impetus of the reactive force of the deck 2 on the link 9 when locking the deck in the deployed position.
- the upper lug 32A of the yoke 32 is pushed against the pivot axis 15 and, conversely, the lower lug 32B is pulled against this axis of rotation. 15. Consequently, the one or more tooth portions 36 formed in the hole or holes 34 are preferably implanted so as to be able to cooperate, as the case may be, under the effect of this thrust or traction, with the peripheral toothing that comprises the axis 15. More particularly, if each of the holes 34 of the lugs 32A, 32B includes such a portion of toothing 36, they are arranged in a diametrically opposed manner, as desired by the FIGS. Figures 8 and 9 .
- the link 9 which is provided, at each of its ends 10, 12, a yoke 32 with ears 32A, 32B
- the invention is not at all limited to such a construction.
- the self-locking device according to the invention makes it possible to provide a real solution to the disadvantages of self-locking devices of the state of the art.
