Même pour les dispositifs les plus simples, il est nécessaire d'ouvrir les coffres pour accéder aux tambours, les démonter, mettre en place le dispositif et remonter l'ensemble.All these different devices described above must be provided for in the design of the roller shutter. They are put in place when the flap is assembled rolling at the time of installation or manufacture. Even for devices the simpler, it is necessary to open the chests to access the drums, dismantle them, set up the device and reassemble the assembly.

L'invention évite tous ces inconvénients.The invention avoids all these drawbacks.

Le dispositif selon l'invention peut être mis en place sur tous les volets roulants existants et quel que soit le jeu latéral dans les coulisses. Il suffit d'intervenir dans la partie basse du volet sans rien démonter. La pose est donc simple, rapide et peu onéreuse.The device according to the invention can be implemented on all the shutters existing rollers and whatever the side play behind the scenes. It is enough to intervene in the lower part of the shutter without dismantling anything. The pose is therefore simple, fast and inexpensive.

Le dispositif de verrouillage et de déverrouillage automatique d'un volet roulant est composé d'un verrou rotatif qui coopère avec une butée de blocage, ledit verrou étant actionné par un organe de manoeuvre, l'ensemble étant disposé dans la partie basse du volet roulant.The automatic locking and unlocking device of a shutter roller is composed of a rotary lock which cooperates with a locking stop, said lock being actuated by an operating member, the assembly being arranged in the lower part of the roller shutter.

Le dispositif selon l'invention est apte à être mis en place sur un volet existant déjà en fonction.The device according to the invention is suitable for being placed on a shutter already existing in function.

Selon un mode de réalisation préférentiel, le verrou rotatif est monté avec son support sur la dernière lame basse du volet roulant, la butée de blocage avec laquelle il coopère est montée en regard sur la coulisse dudit volet.According to a preferred embodiment, the rotary lock is mounted with its support on the last lower blade of the roller shutter, the stop blocking with which it cooperates is mounted opposite on the slide of said shutter.

L'organe de manoeuvre est monté sur l'une des avant-dernières lames basses du volet roulant, de manière à agir sur la rotation de la tige du verrou rotatif qui tourne lorsqu'elle est libérée de l'organe de manoeuvre du fait de sa forme et de son poids pour coopérer avec la butée de blocage.The actuator is mounted on one of the penultimate blades low of the shutter, so as to act on the rotation of the bolt rod rotary which rotates when released from the operating member due to its shape and its weight to cooperate with the locking stop.

Le verrou rotatif est fixé sur son support, lui-même fixé à la dernière lame basse. Ledit verrou rotatif a la forme d'une tige qui tourne dans un cylindre tandis que l'extrémité, côté coulisse, a une forme en baïonnette de manière à ce qu'en position haute, il n'y ait pas de blocage avec la butée de blocage, et qu'en position basse, il y ait un blocage dudit volet roulant. The rotary lock is fixed on its support, itself fixed at the last low blade. Said rotary lock has the shape of a rod which turns in a cylinder while the end, on the sliding side, has a bayonet shape so as to that in the high position, there is no blockage with the blocking stop, and that in the low position, there is a blockage of said roller shutter.

L'organe de manoeuvre est constitué d'un cordon fixé à une extrémité sur une des avant-dernières lames basses et à l'autre extrémité sur la tige du verrou rotatif après avoir réalisé un tour mort autour de la tige, le cordon agit pour manoeuvrer la tige du verrou rotatif par le jeu qui existe entre chaque lame.The operating device consists of a cord fixed at one end on one of the penultimate lower blades and on the other end on the rod of the rotary bolt after making a dead turn around the rod, the cord acts to operate the rod of the rotary latch by the play that exists between each blade.

Lorsque les lames basses sont jointives, le volet roulant est complètement baissé, il y ait automatiquement verrouillage et blocage du relevage sans autorisation, et lorsque le volet commence à être relevé dans des conditions normales, il y a automatiquement un déverrouillage et déblocage du relevage dudit volet roulant.When the lower slats are joined, the roller shutter is completely lowered, there is automatic locking and blocking of the lifting without authorization, and when the shutter begins to be raised in normal conditions, there is automatically an unlocking and unblocking of the lifting said rolling shutter.

La tige du verrou rotatif est asservie à une masselotte qui est disposée perpendiculairement à l'axe longitudinal de ladite tige dans une fenêtre du cylindre qui a pour fonction de guider et maintenir en tension le cordon organe de manoeuvre.The rod of the rotary lock is slaved to a counterweight which is arranged perpendicular to the longitudinal axis of said rod in a window of the cylinder which has the function of guiding and keeping in tension the organ cord maneuver.

Le volet roulant comporte un dispositif de déverrouillage automatique de la lame finale basse de chaque côté avec son verrou rotatif et sa butée de blocage sur chaque coulisse. Dans un mode de réalisation où le volet roulant a un tablier de grande dimension, une butée de blocage intermédiaire réglable en hauteur est prévue.The roller shutter has an automatic unlocking device of the bottom final blade on each side with its rotary lock and its stop blocking on each slide. In an embodiment where the shutter has a large apron, an intermediate locking stop adjustable in height is provided.

Les dessins ci-joints sont donnés à titre d'exemples et ne sont pas limitatifs de l'invention. Ils représentent seulement un mode de réalisation de l'invention et permettront de la comprendre aisément.The attached drawings are given as examples and are not limiting of the invention. They represent only one embodiment of the invention and will make it easy to understand.

La figure 2 est une vue de face du volet roulant dans sa partie basse du côté d'une des coulisses, ledit volet roulant étant en position fermée.Figure 2 is a front view of the roller shutter in its lower part of the side of one of the slides, said roller shutter being in the closed position.

La figure 3 est une vue selon la figure 2 mais où le volet roulant est en position de début d'ouverture lorsque se crée un jeu entre les lames de la partie basse du volet.Figure 3 is a view according to Figure 2 but where the shutter is in opening start position when there is play between the blades of the part shutter bass.

La figure 4 est une vue de détail du dispositif de verrouillage et de déverrouillage automatique mettant en évidence la forme de la tige du verrou rotatif et la butée de blocage. Sur la figure 4, le dispositif est représenté en position de blocage et de verrouillage. En pointillé est représentée la position du verrou rotatif et de sa tige en position de déverrouillage et de déblocage dudit volet.Figure 4 is a detail view of the locking device and automatic unlocking highlighting the shape of the lock rod rotary and locking stop. In Figure 4, the device is shown in blocking and locking position. In dotted line is represented the position of the rotary lock and its rod in the unlocking and unlocking position of said shutter.

Le dispositif selon l'invention a l'avantage de pouvoir être mis en place sur les volets roulants déjà existants.The device according to the invention has the advantage of being able to be put in place on already existing roller shutters.

Ce dispositif de verrouillage et de déverrouillage automatique d'un volet roulant 1 est composé d'un verrou rotatif 2 qui coopère avec une butée de blocage 3, ledit verrou rotatif 1 est actionné par un organe de manoeuvre 4, l'ensemble étant disposé dans la partie basse du volet roulant 1.This automatic locking and unlocking device for a shutter roller 1 is composed of a rotary bolt 2 which cooperates with a stop blocking 3, said rotary lock 1 is actuated by an operating member 4, the assembly being arranged in the lower part of the shutter 1.

Comme représenté sur les figures, le verrou rotatif 2 est monté sur un support 5, lui-même fixé sur la dernière lame 6 basse du volet roulant 1.As shown in the figures, the rotary latch 2 is mounted on a support 5, itself fixed on the last lower blade 6 of the roller shutter 1.

La butée de blocage 3 avec laquelle il coopère est montée en regard sur la coulisse 7 dudit volet roulant 1.The locking stop 3 with which it cooperates is mounted opposite on the slide 7 of said rolling shutter 1.

Cette butée de blocage 3 est mobile, et peut être réglée en hauteur.This locking stop 3 is movable, and can be adjusted in height.

L'organe de manoeuvre 4 est monté sur l'une des avant dernières lames 8, lame basse du volet roulant 1.The operating member 4 is mounted on one of the penultimate blades 8, lower blade of the roller shutter 1.

Le verrou rotatif 2 a la forme d'une tige 9 qui tourne dans un cylindre 10, tandis que l'extrémité, côté coulisse, a une forme en baïonnette, de manière à ce qu'en position haute, il n'y ait pas de blocage avec la butée de blocage 3 (voir la figure 3), et qu'au contraire, en position basse (voir la figure 2) il y ait un blocage du volet roulant par la tige 9 du verrou rotatif 2.The rotary bolt 2 has the shape of a rod 9 which turns in a cylinder 10, while the end, sliding side, has a bayonet shape, so that in the high position, there is no blockage with the blocking stop 3 (see figure 3), and on the contrary, in the low position (see figure 2) there is a blocking of the roller shutter by the rod 9 of the rotary lock 2.

L'organe de manoeuvre 4 est constitué d'un cordon 11 fixé par une de ses extrémités 12 sur une des avant dernières lames basses 8 et à l'autre extrémité 13, sur la tige 9 du verrou 2, et ce, après avoir réalisé un tour mort autour de ladite tige 9. Le cordon 11 agit pour manoeuvrer la tige 9 du verrou rotatif 2 par le jeu 14 qui existe entre chaque lame. Lorsque le cordon libère la tige 9, celle-ci tourne du fait de son poids et de sa forme par exemple en baïonnette pour venir coopérer avec la butée de blocage 3. En relevant le store, les lames se relèvent, le cordon 11 fait tourner la tige 9 qui se libère de la butée de blocage 9.The operating member 4 consists of a cord 11 fixed by one of its ends 12 on one of the penultimate lower blades 8 and on the other end 13, on the rod 9 of the lock 2, and this, after having carried out a dead turn around said rod 9. The cord 11 acts to maneuver the rod 9 of the latch rotary 2 by the clearance 14 which exists between each blade. When the cord releases the rod 9, this rotates due to its weight and its shape for example in bayonet to cooperate with the locking stop 3. By raising the blind, the blades are raised, the cord 11 rotates the rod 9 which is released from the stop blocking 9.

L'organe de manoeuvre 4 agit lorsque les lames basses sont jointives et ce, de manière à ce que lorsque le volet roulant 1 est complètement baissé, il y ait automatiquement un verrouillage et un blocage du relevage sans autorisation et lorsque le volet roulant commence à être relevé dans des conditions normales, il y ait automatiquement un déverrouillage ou un blocage du relevage dudit volet roulant.The actuator 4 acts when the lower blades are joined and this, so that when the roller shutter 1 is completely lowered, there automatically locks and blocks the lift without authorization and when the roller shutter begins to be raised in normal conditions, there is automatically unlocking or blocking lifting said roller shutter.

La tige 9 du verrou rotatif 2 est asservie à une masselotte 15 qui est disposée dans une fenêtre 16 du cylindre 10. Cette masselotte 15 a pour fonction de guider et maintenir en tension le cordon 11, organe de manoeuvre 4 dudit verrou rotatif 2. The rod 9 of the rotary bolt 2 is slaved to a counterweight 15 which is disposed in a window 16 of the cylinder 10. This counterweight 15 has for function of guiding and keeping in tension the cord 11, operating member 4 of said rotary lock 2.
