Description

La présente invention concerne un dispositif de commande d'un mécanisme de verrouillage de porte, plus particulièrement pour une porte d'une cage de Faraday.The present invention relates to a device for controlling a door locking mechanism, more particularly for a door of a Faraday cage.

On connaît des mécanismes de verrouillage de porte qui ne peuvent être commandés de l'extérieur que par des personnes autorisées munies d'une clé ou d'une carte magnétique, et qui comportent du côté intérieur de la porte une poignée de sécurité permettant à toute personne enfermée dans l'enceinte close par la porte d'en sortir librement. Afin de permettre un déverrouillage de la porte, soit de l'extérieur soit de l'intérieur, le mécanisme de verrouillage de porte comporte généralement des moyens de commande séparés agissant sur le mécanisme de verrouillage indépendamment l'un de l'autre. Cette indépendance implique des mécanismes relativement complexes. En outre, pour satisfaire aux contraintes d'encombrement, les mécanismes de commande indépendants sont réalisés au moyen de pièces de petite dimension qui sont donc susceptibles de se rompre après un usage prolongé ou dans des conditions d'usage impliquant des contraintes élévées.Door locking mechanisms are known which can only be controlled from the outside by authorized persons provided with a key or a magnetic card, and which comprise on the inside of the door a security handle allowing any person locked in the enclosure closed by the door to leave freely. In order to allow the door to be unlocked, either from the outside or from the inside, the door locking mechanism generally comprises separate control means acting on the locking mechanism independently of one another. This independence involves relatively complex mechanisms. In addition, to meet the space constraints, the independent control mechanisms are produced by means of small parts which are therefore liable to break after prolonged use or under conditions of use involving high constraints.

Dans certaines applications, notamment lorsque la porte est destinée à fermer une enceinte à usage militaire, les contraintes mentionnées ci-dessus sont incompatibles avec les exigences de fonctionnement.In certain applications, in particular when the door is intended to close an enclosure for military use, the constraints mentioned above are incompatible with the operating requirements.

On connaît également des mécanismes de verrouillage dans lesquels deux poignées disposées de part et d'autre de la porte sont reliées rigidement entre elles et servent à manoeuvrer le mécanisme. Ces structures sont solides mais si l'une des poignées est bloquée, l'autre l'est également et il n'y a donc pas de possibilité d'un déverrouillage de sécurité.Locking mechanisms are also known in which two handles arranged on either side of the door are rigidly connected to one another and are used to operate the mechanism. These structures are solid but if one of the handles is blocked, the other is also locked and there is therefore no possibility of a safety unlocking.

On connaît de plus des dispositifs de sécurité qui permettent d'ouvrir des mécanismes de verrouillage pour portes d'enceintes. Ce genre de dispositif présente une tige de commande qui fait saillie à l'intérieur de l'enceinte et qui porte une poignée de commande solidaire, en rotation de la tige. Lorsque la porte est fermée de l'extérieur, une rotation de la poignée de commande intérieure permet l'ouverture. Cependant, si la poignée extérieure n'est pas correctement enclenchée, le dispositif de sécurité est inefficace car la poignée de commande intérieure ainsi que la tige ne peuvent plus être entraînées en rotation.Security devices are also known which make it possible to open locking mechanisms for speaker doors. This type of device has a control rod which projects inside the enclosure and which carries an integral control handle, in rotation of the rod. When the door is closed from the outside, a rotation of the interior control handle allows opening. However, if the exterior handle is not properly engaged, the safety device is ineffective since the interior control handle and the rod can no longer be rotated.

On connait toutefois par le document DE-A-3 310 004, un dispositif de sécurité permettant l'ouverture de mécanismes de verrouillage. Ce mécanisme présente une tige de commande qui fait saillie à l'intérieur de l'enceinte et qui porte une poignée de commande solidaire en rotation de la tige. Lorsque la porte est fermée de l'extérieur, une rotation de la poignée de commande intérieure permet l'ouverture: il s'agit donc d'un mécanisme débrayable qui permet de solidariser ou non les deux organes d'ouverture.However, document DE-A-3 310 004 discloses a safety device allowing the opening of locking mechanisms. This mechanism has a control rod which projects inside the enclosure and which carries a control handle integral in rotation with the rod. When the door is closed from the outside, a rotation of the interior control handle allows the opening: it is therefore a disengageable mechanism which allows to join or not the two opening members.

Le but de la présente invention est de réaliser un dispositif de commande d'un mécanisme de déverrouillage de porte qui soit particulièrement adapté à la commande d'une porte fermant une cage de Faraday, c'est à dire qui permette une isolation électrique totale de l'extérieur de la cage par rapport à l'intérieur, le tout en étant de structure simple et résistance pour assurer les fonctions de déverrouillage sélectif depuis l'extérieur de la porte et de déverrouillage en toutes circonstances depuis l'intérieur de la porte.The object of the present invention is to provide a device for controlling a door unlocking mechanism which is particularly suitable for controlling a door closing a Faraday cage, that is to say which allows total electrical insulation of the outside of the cage relative to the inside, while being of simple structure and resistance to ensure the functions of selective unlocking from the outside of the door and unlocking in all circumstances from the inside of the door.

L'invention a donc pour objet un dispositif du type de celui montré dans le document, ci-dessus c'est-à-dire pour commander un mécanisme de verrouillage de porte comportant deux organes de commande disposés de part et d'autre de la porte, des moyens pour relier les organes de commande au mécanisme de verrouillage, et des moyens débrayables pour relier entre eux les organes de commande, caractérisé en ce que les moyens débrayables comportent un manchon intermédiaire qui comporte deux parties de manchon métalliques séparées par un corps électriquement isolant assurant une liaison mécanique entre les parties du manchon et qui est traversé par des tiges de commande solidaires des organes de commande, l'une des tiges de commande étant mobile en translation suivant l'axe du manchon intermédiaire pour sortir de la partie de manchon, tout en s'étendant à travers le mécanisme de verrouillage. Ainsi, lors du blocage de l'organe de commande extérieur, l'autre organe de commande est désolidarisé de l'organe bloqué en déplaçant la tige de commande mobile en translation jusqu'à ce qu'elle soit désolidarisée du manchon intermédiaire, et la résistance mécanique de l'ensemble est assurée par les parties de manchon métalliques tandis que le corps électriquement isolant évite un effet d'antenne entre les organes de commande.The invention therefore relates to a device of the type shown in the document above, that is to say to control a door locking mechanism comprising two control members disposed on either side of the door, means for connecting the control members to the locking mechanism, and disengageable means for connecting the control members together, characterized in that the disengageable means comprise an intermediate sleeve which comprises two metal sleeve parts separated by a body electrically insulating ensuring a mechanical connection between the parts of the sleeve and which is crossed by control rods integral with the control members, one of the control rods being movable in translation along the axis of the intermediate sleeve to exit from the part of sleeve, while extending through the locking mechanism. Thus, when the external control member is blocked, the other control member is detached from the blocked member by moving the movable control rod in translation until it is detached from the intermediate sleeve, and the mechanical resistance of the assembly is ensured by the metal sleeve parts while the electrically insulating body avoids an antenna effect between the control members.

Selon une version avantageuse de cet aspect de l'invention, le corps électriquement isolant a une section polygonale et coopère avec des logements de section correspondante réalisés dans les partie de manchon. Ainsi, la liaison mécanique entre les parties de manchon métalliques est assurée par simple emboîtement du corps isolant entre les parties de manchon.According to an advantageous version of this aspect of the invention, the electrically insulating body has a polygonal section and cooperates with housings of corresponding section made in the sleeve parts. Thus, the mechanical connection between the metal sleeve parts is ensured by simple fitting of the insulating body between the sleeve parts.

Selon un mode de réalisation particulièrement adapté à une porte comportant deux parois espacées, le manchon intermédiaire est entouré par un boîtier isolant fixé à chacune des parois. Ainsi, le boîtier isolant est utilisé comme entretoise supplémentaire entre les parois de la porte au niveau du mécanisme de verrouillage tout en maintenant une isolation électrique entre ces parois.According to an embodiment particularly suitable for a door having two spaced walls, the intermediate sleeve is surrounded by an insulating housing fixed to each of the walls. Thus, the insulating housing is used as an additional spacer between the walls of the door at the locking mechanism while maintaining electrical insulation between these walls.

D'autres caractéristiques et avantages de l'invention résulteront encore de la description ci-après d'un exemple non limitatif en référence aux dessins annexés parmi lesquels:

  • - la figure 1 est une vue en coupe partielle du dispositif de commande selon l'invention dans une position où les organes de commande sont solidaires,
  • - la figure 2 est une vue en coupe analogue à celle de la figure 1 dans laquelle l'un des organes de commande est bloqué et l'autre organe de commande est désolidarisé,
  • - la figure 3 est une vue de face d'un mode de réalisation de clavette de retenue,
  • - la figure 4 est une vue en coupe selon le plan IV-IV de la figure 1.
Other characteristics and advantages of the invention will also result from the following description of a nonlimiting example with reference to the accompanying drawings, in which:
  • - Figure 1 is a partial sectional view of control device according to the invention in a position where the control members are integral,
  • FIG. 2 is a sectional view similar to that of FIG. 1 in which one of the control members is blocked and the other control member is separated,
  • FIG. 3 is a front view of an embodiment of a retaining key,
  • - Figure 4 is a sectional view along the plane IV-IV of Figure 1.

En référence aux figures, le dispositif de commande selon l'invention comporte deux organes de commande 1, 2 formés par des poignées disposées de part et d'autre d'une porte généralement désignée en 3 et comportant deux parois 4, 5 espacées l'une de l'autre. Les poignées de commande 1, 2 sont reliées entre elles par des moyens débrayables comportant une tige de commande 6 solidaire de la poignée de commande 1 et une tige de commande 7 solidaire de la poignée de commande 2, reliées entre elles par un manchon intermédiaire généralement désigné en 8 et comportant une partie de manchon métallique 8.1 associée à la tige de commande 6 et une partie de manchon métallique 8.2 associée à la tige de commande 7, les parties de manchon 8.1 et 8.2 étant elles- mêmes reliées mécaniquement l'une à l'autre par un corps électriquement isolant 9. Afin de permettre un entraînement des parties de manchon par les tiges de commande respectives, chaque tige de commande a une extrémité de section carrée s'engageant dans une ouverture carrée 10 de la partie de manchon correspondante (figure 4). De même, afin d'assurer une liaison mécanique entre les parties de manchon, le corps électriquement isolant 9 a de préférence une section polygonale, par exemple une section carrée et coopère avec des logements 11 de section correspondante réalisés dans les parties de manchon 8.1, 8.2. Afin d'assurer une meilleure cohésion de l'assemblage, le corps isolant 9 est de préférence fixé à la partie de manchon 8.1 par des vis 12.With reference to the figures, the control device according to the invention comprises two control members 1, 2 formed by handles arranged on either side of a door generally designated at 3 and comprising two walls 4, 5 spaced apart. one of the other. The control handles 1, 2 are interconnected by disengageable means comprising a control rod 6 secured to the control handle 1 and a control rod 7 secured to the control handle 2, connected together by an intermediate sleeve generally designated at 8 and comprising a metal sleeve part 8.1 associated with the control rod 6 and a metal sleeve part 8.2 associated with the control rod 7, the sleeve parts 8.1 and 8.2 being themselves mechanically connected to one another the other by an electrically insulating body 9. In order to allow the sleeve parts to be driven by the respective control rods, each control rod has a square section end engaging in a square opening 10 in the corresponding sleeve part (figure 4). Likewise, in order to ensure a mechanical connection between the sleeve parts, the electrically insulating body 9 preferably has a polygonal section, for example a square section and cooperates with housings 11 of corresponding section made in the sleeve parts 8.1, 8.2. In order to ensure better cohesion of the assembly, the insulating body 9 is preferably fixed to the sleeve part 8.1 by screws 12.

Le manchon intermédiaire 8 est entouré par un boîtier isolant 13 ayant une extrémité fixée à la paroi 4 par des boulons 14 dont la tête prend appui sur une contreplaque externe 15 et l'autre extrémité du boîtier isolant 13 est fixée à une contreplaque 16, elle-même fixée à la paroi 5 par des rivets 17, au moyen de vis 18 s'engageant dans des trous taraudés d'une couronne 19 prenant appui sur un rebord externe 20 du boîtier isolant 13.The intermediate sleeve 8 is surrounded by an insulating housing 13 having one end fixed to the wall 4 by bolts 14 whose head is supported on an external plywood 15 and the other end of the insulating housing 13 is fixed to a plywood 16, it even fixed to the wall 5 by rivets 17, by means of screws 18 engaging in tapped holes of a ring 19 bearing on an external flange 20 of the insulating housing 13.

La tige de commande 7 associée à la poignée de commande 2 traverse également un mécanisme de verrouillage 21, par exemple une crémone comportant des barres de verrouillage 22. Le mécanisme de verrouillage a une structure connue en elle-même et il est inutile d'en donner une description détaillée. Le mécanisme de verrouillage 21 est fixé par des moyens appropriés (non représentés) à la contreplaque 16. La tige de commande 7 est mobile en translation suivant l'axe du manchon intermédiaire 8 et sa position est déterminée en tirant ou en poussant l'organe de commande 2. Afin que la tige de commande 7 soit normalement retenue insérée dans l'ouverture 10 de la partie du manchon 8.2, cette tige de commande 7 comporte une collerette 23 s'étendant dans une douille 24 fixée au mécanisme de verrouillage 21. Une gorge annulaire 25 est réalisée dans la collerette 23 et une clavette 26 en forme de U (figure 3) a ses ailes 27 engagées transversalement dans la douille 24 et s'étendant dans la gorge 25 de part et d'autre de l'axe de la tige de commande 7. La clavette 26 est elle-même maintenue en place par une goupille 28 engagée dans un trou 29 de la clavette 26 et maintenue par une saillie 30 solidaire de la douille 24.The control rod 7 associated with the control handle 2 also passes through a locking mechanism 21, for example a cremone bolt comprising locking bars 22. The locking mechanism has a structure known in itself and there is no need to give a detailed description. The locking mechanism 21 is fixed by appropriate means (not shown) to the counterplate 16. The control rod 7 is movable in translation along the axis of the intermediate sleeve 8 and its position is determined by pulling or pushing the member control rod 2. So that the control rod 7 is normally retained inserted in the opening 10 of the part of the sleeve 8.2, this control rod 7 comprises a flange 23 extending in a socket 24 fixed to the locking mechanism 21. An annular groove 25 is produced in the flange 23 and a key 26 in the shape of a U (FIG. 3) has its wings 27 engaged transversely in the sleeve 24 and extending in the groove 25 on either side of the axis of the control rod 7. The key 26 is itself held in place by a pin 28 engaged in a hole 29 in the key 26 and held by a projection 30 integral with the socket 24.

L'extrémité de la tige de commande 7 opposée à celle qui est engagée dans la partie de manchon 8.2 comporte une tête de section carrée 31 sur laquelle est engagée la poignée de commande 2 maintenue en place par une rondelle 32 et une vis 33.The end of the control rod 7 opposite to that which is engaged in the sleeve part 8.2 comprises a square section head 31 on which is engaged the control handle 2 held in place by a washer 32 and a screw 33.

A son extrémité opposée à la tige de commande 6, la poignée de commande 1 comporte un bec 34 percé d'une ouverture 35 en regard d'une ouverture 36 réalisée dans une saillie 37 solidaire de la paroi 4 de la porte 3, pour position verrouillée de la porte.At its end opposite to the control rod 6, the control handle 1 has a spout 34 pierced with an opening 35 opposite an opening 36 formed in a projection 37 integral with the wall 4 of the door 3, for position locked from the door.

Le fonctionnement du dispositif selon l'invention est le suivant: en position normale de fonctionnement, illustré par la figure 1, la tige de commande 7 est enfoncée dans l'ouverture 10 de la partie de manchon 8.2 et les poignées de commande 1 et 2 sont reliées l'une à l'autre par le manchon intermédiaire 8 enserrant le corps 9. Dans cette position, un effort exercé sur l'une ou l'autre des poignées de commande 1 et 2 entraîne la manoeuvre du mécanisme de verrouillage 21. Lors de la fermeture de la porte à partir de l'intérieur, une traction est exercée sur la poignée de commande 2 pour maintenir la porte fermée pendant son verrouillage. Lorsque cette traction est exercée, la tige de commande 7 est retenue engagée dans l'ouverture 10 de la partie de manchon 8.2 par la clavette 26 engagée dans la gorge 25 de la collerette 23.The operation of the device according to the invention is as follows: in the normal operating position, illustrated by FIG. 1, the control rod 7 is pressed into the opening 10 of the sleeve part 8.2 and the control handles 1 and 2 are connected to each other by the intermediate sleeve 8 enclosing the body 9. In this position, a force exerted on one or the other of the control handles 1 and 2 causes the locking mechanism 21 to operate. When closing the door from the inside, traction is exerted on the control handle 2 to keep the door closed while it is locked. When this traction is exerted, the control rod 7 is retained engaged in the opening 10 of the sleeve part 8.2 by the key 26 engaged in the groove 25 of the flange 23.

Dans la position illustrée par la figure 2 où la poignée de commande est bloquée par un cadenas 38, et dans le cas où une personne aurait par inadvertance été enfermée à l'intérieur d'une enceinte délimitée par la porte 3, il est nécessaire que cette personne puisse actionner le mécanisme de verrouillage 21 pour se libérer. Cependant, dans la position initiale, la poignée de commande 2 est également bloquée en raison de sa solidarité avec la poignée de commande 1.In the position illustrated in FIG. 2 where the control handle is blocked by a padlock 38, and in the case where a person has inadvertently been locked inside an enclosure delimited by the door 3, it is necessary that this person can actuate the locking mechanism 21 to free themselves. However, in the initial position, the control handle 2 is also blocked because of its solidarity with the control handle 1.

Afin de permettre la manoeuvre du mécanisme de verrouillage 21, la poignée de commande 2 doit donc être désolidarisée de la poignée de commande 1. Pour cela, la goupille 28 est arrachée et la clavette 26 est retirée de son logement, ce qui libère la collerette 23 et permet un déplacement axial de la tige de commande 7, comme illustré par les flèches sur la figure 2. Lors de son déplacement en translation, la tige de commande 7 sort du logement 10 dans la partie de manchon 8.2, mais continue néanmoins à s'étendre à travers le mécanisme de verrouillage 21. Etant libérée de la partie de manchon 8.2, la tige de commande 7 peut être librement manoeuvrée au moyen de la poignée de commande 2 afin d'ouvrir la porte.In order to allow the locking mechanism 21 to operate, the control handle 2 must therefore be detached from the control handle 1. For this, the pin 28 is torn off and the key 26 is removed from its housing, which releases the flange 23 and allows an axial displacement of the control rod 7, as illustrated by the arrows in FIG. 2. During its displacement in translation, the control rod 7 leaves the housing 10 in the sleeve part 8.2, but nevertheless continues to extend through the locking mechanism 21. Being released from the sleeve part 8.2, the control rod 7 can be freely maneuvered by means of the control handle 2 in order to open the door.

Dans les deux positions de fonctionnement illustrées, on constate que le corps 9 et le boîtier isolant 13 assurent une isolation électrique entre les deux parois 4 et 5 de la porte 3, de sorte qu'aucun effet d'antenne n'existe entre les poignées de commande 1 et 2 et, dans le cas où la porte fait partie d'une cage de Faraday, l'isolation du volume interne contre une pénétration des ondes électromagnétiques est convenablement assurée.In the two illustrated operating positions, it can be seen that the body 9 and the insulating box 13 provide electrical insulation between the two walls 4 and 5 of the door 3, so that no antenna effect exists between the handles. 1 and 2 and, in the case where the door is part of a Faraday cage, the isolation of the internal volume against penetration of electromagnetic waves is suitably ensured.

Bien entendu, l'invention n'est pas limitée aux modes de réalisation décrits ci-dessus et on peut y apporter des variantes d'exécution.Of course, the invention is not limited to the embodiments described above and it is possible to make variant embodiments.

En particulier, les tiges de commande 7 et 9 de section carrée peuvent être remplacées par des tiges ayant d'une façon générale une section polygonale, voire une section circulaire avec des ergots d'entraînement coopérant avec des rainures dans les parties de manchon 8.1 et 8.2.In particular, the control rods 7 and 9 of square section can be replaced by rods generally having a polygonal section, or even a circular section with drive pins cooperating with grooves in the sleeve parts 8.1 and 8.2.
