Description

Objet de l'inventionSubject of the invention

La présente invention concerne un dispositif de sécurité de volets mécaniques (ou encore appelés volets roulants) qui les bloque automatiquement de manière qu'ils ne puissent être ouverts par l'extérieur, en particulier en cas d'infraction.The present invention relates to a security device for mechanical shutters (or also called roller shutters) which automatically blocks them so that they cannot be opened from the outside, in particular in the event of a violation.

Description de l'état de la techniqueDescription of the state of the art

Il existe de nombreux systèmes de protection de volets mécaniques qui agissent au moyen d'une serrure ou d'un verrou. A titre d'exemple on peut obtenir un verrouillage d'un volet en utilisant un ou plusieurs verrous latéraux. Il est bien entendu qu'un tel système de fermeture n'est pas automatique, et on risque par conséquent d'oublier d'enclencher ledit verrou lors de l'ouverture du volet.There are many systems for protecting mechanical shutters which act by means of a lock or bolt. For example, a shutter can be locked by using one or more lateral locks. It is understood that such a closing system is not automatic, and there is therefore a risk of forgetting to engage said latch when the shutter is opened.

Le document FR-A-2 609 095 décrit un dispositif de verrouillage automatique de volets roulants. Dans un caisson métallique sont logés le tablier et l'arbre d'enroulement du volet. Le dispositif de verrouillage est essentiellement constitué d'une première série de saillies en dents de scie disposée verticalement sur la face interne du caisson sensiblement en regard d'au moins une des deux dernières lattes du tablier lorsque celui-ci est en position complètement abaissée et d'une seconde série de saillies également en dents de scie disposée sur la face externe des deux dernières lattes du tablier.Document FR-A-2 609 095 describes an automatic locking device for roller shutters. In a metal box are housed the apron and the shutter winding shaft. The locking device essentially consists of a first series of sawtooth projections arranged vertically on the internal face of the box substantially facing at least one of the last two slats of the apron when the latter is in the fully lowered position and a second series of projections also sawtooth disposed on the outer face of the last two slats of the deck.

Ces séries de saillies disposées sur les lattes présentent le principal inconvénient qu'elles sont enroulées avec le tablier, ce qui rend l'enroulement moins compact et risque de provoquer une usure ou une détérioration lors des opérations successives d'enroulement et de déroulement du tablier.These series of projections arranged on the slats have the main drawback that they are wound with the apron, which makes the winding less compact and risks causing wear or deterioration during the successive operations of winding and unwinding the apron. .

Un second inconvénient réside dans le fait que les deux séries de saillies doivent être positionnées avec précision de façon à ce qu'elles s'interpénètrent lorsque le volet est déroulé.A second drawback lies in the fact that the two series of projections must be positioned precisely so that they interpenetrate when the shutter is unrolled.

Enfin un dernier inconvénient réside dans le fait que soit il faut un caisson de grande dimension, soit la série inférieure de saillies disposée sur les lattes du volet est visible de l'extérieur. Dans ce dernier cas, le dispositif de verrouillage est moins efficace parce que visible, ce qui permet de savoir comment il faut le forcer.Finally a last drawback lies in the fact that either a large box is required, or the lower series of projections arranged on the slats of the shutter is visible from the outside. In the latter case, the locking device is less effective because it is visible, which makes it possible to know how to force it.

Le document BE-A-332 413 décrit également un dispositif de verrouillage automatique d'un volet roulant qui comprend un élément de blocage muni de dents et monté sur les parois latérales de la baie. Les dents sont dirigées vers l'extérieur par rapport à l'axe d'enroulement et de ce fait les lattes du volet doivent être poussées vers l'intérieur pour obtenir un blocage de la latte supérieure dans lesdites dents.Document BE-A-332 413 also describes an automatic locking device for a roller shutter which comprises a locking element provided with teeth and mounted on the side walls of the bay. The teeth are directed outward relative to the winding axis and therefore the slats of the flap must be pushed inward to obtain a blocking of the upper slat in said teeth.

En outre, pour ce dispositif de verrouillage, la lamelle ou latte supérieure du tablier est directement reliée à l'arbre d'enroulement par une bande élastique.In addition, for this locking device, the upper slat or slat of the deck is directly connected to the winding shaft by an elastic band.

Le document DE-A-25 18 356 décrit un dispositif de verrouillage pour volets mécaniques comportant une tige élastique perpendiculaire au cylindre d'enroulement du volet et qui va se bloquer contre un arrêt mobile solidaire du tablier lorsque l'on tente de remonter le volet de l'extérieur.Document DE-A-25 18 356 describes a locking device for mechanical shutters comprising an elastic rod perpendicular to the winding cylinder of the shutter and which will lock against a movable stop integral with the apron when an attempt is made to reassemble the shutter from the outside.

Le document EP-A-0 242 317 décrit un dispositif de verrouillage pour volets comprenant un élément d'arrêt qui est fixé sur le montant dans lequel glisse les lamelles du tablier du volet et un élément mobile faisant saillie situé sur l'une des lamelles de manière à ce qu'il s'emboîte dans l'élément d'arrêt verrouillant ainsi le volet lorsqu'on tente de le remonter de l'extérieur.Document EP-A-0 242 317 describes a locking device for shutters comprising a stop element which is fixed on the upright in which the slats of the shutter apron slide and a movable protruding element situated on one of the slats so that it fits into the stop element thus locking the shutter when trying to reassemble it from the outside.

Le document CH-A-657 663 décrit un verrou automatique de fermeture d'un volet roulant. Ce verrou est constitué d'un élément de blocage mobile monté sur une charnière portée par la lamelle supérieure du volet roulant. Lorsque le volet est fermé cet élément de blocage s'engage sous des crochets présents sur le montant de glissement du tablier du volet.The document CH-A-657 663 describes an automatic lock for closing a roller shutter. This lock consists of a movable blocking element mounted on a hinge carried by the upper lamella of the roller shutter. When the shutter is closed, this blocking element engages under hooks present on the sliding amount of the shutter deck.

Ces deux derniers systèmes de verrouillage présentent l'inconvénient de devoir être particulièrement bien ajustés et ne fonctionnent que dans le cas où le volet est complètement déroulé. En outre ils sont fort complexes et présentent l'inconvénient supplémentaire d'être visibles au moins de l'intérieur.These last two locking systems have the disadvantage of having to be particularly well adjusted and only work if the shutter is fully extended. In addition, they are very complex and have the additional disadvantage of being visible at least from the inside.

Le but de la présente invention vise à proposer un dispositif de verrouillage automatique pour volets mécaniques qui soit particulièrement simple et qui évite les inconvénients de l'état de la technique.The object of the present invention is to propose an automatic locking device for mechanical shutters which is particularly simple and which avoids the drawbacks of the state of the art.

Description détaillée de deux formes particulières d'exécution de la présente inventionDetailed description of two particular embodiments of the present invention

Selon les deux formes d'exécution particulières de l'invention représentées respectivement aux figures 1A à 1C et aux figures 2A à 2C, un arbre d'enroulement 1 permet d'enrouler le tablier 3 d'un volet à l'aide d'un mécanisme d'entraînement (non représenté). Des éléments ressorts 5 constituent la liaison entre l'arbre d'enroulement 1 et le tablier 3 constitué de lamelles 31.According to the two particular embodiments of the invention shown respectively in FIGS. 1A to 1C and in FIGS. 2A to 2C, a winding shaft 1 makes it possible to wind the deck 3 of a shutter using a drive mechanism (not shown). Spring elements 5 constitute the connection between the winding shaft 1 and the deck 3 made up of strips 31.

Selon une première caractéristique essentielle de la présente invention, les éléments ressorts 5 sont configurés de manière à repousser les lamelles 31 supérieures du tablier 3 vers l'extérieur par rapport à l'arbre d'enroulement 1.According to a first essential characteristic of the present invention, the spring elements 5 are configured so as to push the upper slats 31 of the deck 3 outwards relative to the winding shaft 1.

Selon une seconde caractéristique essentielle de la présente invention, une des lamelles 31 supérieures du tablier 3 se présente sous la forme d'un profil tubulaire 33 muni à au moins une extrémité latérale et de préférence à ses deux extrémités d'un embout de blocage 41.According to a second essential characteristic of the present invention, one of the upper slats 31 of the deck 3 is in the form of a tubular profile 33 provided at at least one lateral end and preferably at its two ends with a locking end piece 41 .

Selon une troisième caractéristique essentielle du dispositif de verrouillage selon la présente invention, au moins un élément d'arrêt 11 et de préférence deux éléments d'arrêt 11 sont disposés de part et d'autre aux extrémités latérales du tablier 3 et en vis-à-vis avec au moins une des lamelles 31 supérieures du tablier 3, et plus particulièrement avec la lamelle qui se présente sous la forme d'un profil tubulaire 33.According to a third essential characteristic of the locking device according to the present invention, at least one stop element 11 and preferably two stop elements 11 are arranged on either side at the ends sides of the deck 3 and facing each other with at least one of the upper strips 31 of the deck 3, and more particularly with the strip which is in the form of a tubular profile 33.

Cet élément d'arrêt 11 est constitué d'une série de saillies sous forme de dents 13 qui sont elles-mêmes dirigées vers le bas et en direction de l'arbre d'enroulement 1.This stop element 11 consists of a series of projections in the form of teeth 13 which are themselves directed downwards and in the direction of the winding shaft 1.

Il convient de noter que ces éléments d'arrêt 11 peuvent être disposés sur les faces longitudinales internes d'un caisson 7 qui contient tout le mécanisme d'enroulement du volet.It should be noted that these stop elements 11 can be arranged on the internal longitudinal faces of a box 7 which contains the entire winding mechanism of the shutter.

Ces éléments d'arrêt 11 peuvent être selon une autre forme d'exécution disposés directement contre la paroi ou le mur qui longe les lamelles 31 supérieures du tablier 3 déroulé.These stop elements 11 may be according to another embodiment arranged directly against the wall or the wall which runs along the upper strips 31 of the deck 3 unwound.

Selon la première forme d'exécution préférée de la présente invention, représentée aux figures 1A à 1C, les éléments ressorts 5 sont de simples tiges souples qui relient directement l'arbre d'enroulement 1 à une des lamelles 31 supérieures du tablier 3 et de préférence à la lamelle présentant le profil tubulaire 33 avec les embouts de blocage.According to the first preferred embodiment of the present invention, shown in Figures 1A to 1C, the spring elements 5 are simple flexible rods which directly connect the winding shaft 1 to one of the upper strips 31 of the deck 3 and preferably with the strip having the tubular profile 33 with the locking end pieces.

Selon une seconde forme d'exécution préférée de la présente invention, représentée aux figures 2A à 2C, et plus particulièrement aux figures 3 et 4, les éléments ressorts 5 sont des tiges souples qui d'une part sont directement reliées à une lamelle ou latte 35 elle-même fixée à l'arbre d'enroulement 1, et d'autre part coulissent à l'autre extrémité dans un étrier 37 fixé sur une lamelle ou latte inférieure 36.According to a second preferred embodiment of the present invention, shown in Figures 2A to 2C, and more particularly in Figures 3 and 4, the spring elements 5 are flexible rods which on the one hand are directly connected to a strip or slat 35 itself fixed to the winding shaft 1, and on the other hand slide at the other end in a stirrup 37 fixed on a lamella or lower batten 36.

Ces lattes ou lamelles 35 ou 36 qui sont solidaires de l'élément ressort 5 ou qui sont adjacentes à l'élément ressort 5 sont avantageusement de faible longueur afin d'économiser la matière. On peut bien entendu envisager que les éléments ressorts 5 soient disposés sur des lamelles entières, c'est-à-dire qu'ils coulissent directement sur la partie supérieure du tablier.These slats or strips 35 or 36 which are integral with the spring element 5 or which are adjacent to the spring element 5 are advantageously short in order to save material. It can of course be envisaged that the spring elements 5 are arranged on whole strips, that is to say that they slide directly on the upper part of the deck.

Les figures 5A et 5B représentent plus particulièrement le profil tubulaire 33 qui est solidaire d'une des lamelles 31 supérieures du tablier 3 et qui présente à chacune de ses deux extrémités un embout 41 qui se loge dans une ouverture centrale 47 de l'extrémité du profil 33 et qui est maintenu dans cette ouverture à l'aide d'une rondelle 43 et d'une attache 45.FIGS. 5A and 5B show more particularly the tubular profile 33 which is integral with one of the upper slats 31 of the deck 3 and which has at each of its two ends a nozzle 41 which is housed in a central opening 47 of the end of the profile 33 and which is held in this opening by means of a washer 43 and a fastener 45.

Le mécanisme de fonctionnement du dispositif de verrouillage automatique de volets mécaniques selon la présente invention sera décrit plus précisément dans les 3 situations suivantes :The operating mechanism of the automatic locking device for mechanical shutters according to the present invention will be described more precisely in the following 3 situations:

Situation 1 (représentée aux figures 1A et 2A) : Situation 1 (shown in Figures 1A and 2A) :

  • dans cette situation le tablier 3 du volet est complètement déroulé;in this situation the apron 3 of the shutter is completely unwound;
  • les éléments ressorts 5 poussent les lamelles 31 supérieures du tablier 3 vers l'extérieur par rapport à l'arbre d'enroulement 1;the spring elements 5 push the upper slats 31 of the deck 3 outwards relative to the winding shaft 1;
  • l'embout de blocage 41 se trouve dans une situation de pré-blocage, c'est-à-dire en face de l'élément d'arrêt 11 mais sans être enclenché entre les différentes dents 13 de l'élément d'arrêt 11.the locking end piece 41 is in a pre-locking situation, that is to say in front of the stop element 11 but without being engaged between the different teeth 13 of the stop element 11 .
Situation 2 (représentée aux figures 1B et 2B) : Situation 2 (shown in Figures 1B and 2B) :

  • le tablier 3 qui se trouve en position déroulée est soumis à un mouvement ascendant exécuté de l'extérieur (par exemple lorsqu'on tente d'ouvrir ce volet de l'extérieur en cas d'effraction);the apron 3 which is in the unrolled position is subjected to an upward movement executed from the outside (for example when an attempt is made to open this shutter from the outside in the event of a break-in);
  • l'embout de blocage 41 se positionne entre les dents 13 de l'élément d'arrêt 11;the locking end piece 41 is positioned between the teeth 13 of the stop element 11;
  • le tablier 3 du volet se trouve dans ce cas bloqué et ne peut plus être levé.the apron 3 of the shutter is blocked in this case and can no longer be lifted.
Situation 3 (représentée aux figures 1C et 2C) : Situation 3 (shown in Figures 1C and 2C) :

  • le mécanisme d'entraînement est enclenché afin d'enrouler le tablier 3 autour de l'arbre d'enroulement 1;the drive mechanism is engaged in order to wind the deck 3 around the winding shaft 1;
  • les éléments ressorts 5 induisent un mouvement vers l'intérieur par rapport à l'arbre d'enroulement 1 aux embouts de blocage 41 de manière à les déloger des éléments d'arrêt 11 correspondants;the spring elements 5 induce an inward movement relative to the winding shaft 1 to the locking end pieces 41 so as to dislodge them from the corresponding stop elements 11;
  • le tablier 3 peut être enroulé et le volet peut fonctionner normalement.the apron 3 can be rolled up and the shutter can operate normally.

Le dispositif selon la présente invention fonctionne aussi bien pour des éléments ressorts classiques tels que représentés aux figures 1A à 1C que pour des éléments ressorts reliant différentes lamelles entre elles tels que représentés aux figures 2.The device according to the present invention works as well for conventional spring elements as shown in FIGS. 1A to 1C as for spring elements connecting different lamellae as shown in FIGS. 2.

Avantageusement selon la présente invention il n'est pas nécessaire de prévoir un caisson de logement pour l'arbre d'enroulement et le tablier; en effet les éléments d'arrêt peuvent être directement positionnés contre le mur ainsi que cela est représenté aux figures 2. De même, il n'est pas nécessaire de prévoir des parois latérales (sous forme de baies) pour loger les éléments d'arrêt.Advantageously according to the present invention it is not necessary to provide a housing for the winding shaft and the deck; indeed the stop elements can be directly positioned against the wall as shown in Figures 2. Similarly, it is not necessary to provide side walls (in the form of bays) to accommodate the stop elements .

Il est bien entendu que le dispositif de verrouillage automatique selon la présente invention peut être également disposé sur des grilles de fermeture de magasin par exemple.It is understood that the automatic locking device according to the present invention can also be arranged on grids for closing the shop, for example.

Selon les différentes formes d'exécution préférées représentées dans les figures annexées, on a prévu un seul élément d'arrêt de part et d'autre aux extrémités latérales du tablier et qui comprend chaque fois trois dents; il est bien entendu que diverses modifications évidentes pour l'homme de l'art peuvent être envisagées : par exemple deux éléments d'arrêts peuvent être disposés l'un en dessous de l'autre ou bien on peut augmenter le nombre de dents de telle manière qu'il ne soit plus nécessaire d'effectuer un positionnement précis lors du placement desdits éléments d'arrêt.According to the various preferred embodiments shown in the appended figures, there is provided a single stop element on either side at the lateral ends of the deck and which each comprises three teeth; it is understood that various modifications obvious to a person skilled in the art can be envisaged: for example two stop elements can be arranged one below the other or else the number of teeth can be increased so that it is no longer necessary to perform precise positioning when placing said stop elements.
