Abstract

An electric lock comprises a bolt that is movable into and out of a specially-shaped keeper. The bolt is displaced relative to a casing by a motor that is in turn slidably mounted within the casing. During normal use, the motor is fixed relative to the casing by an electromagnetic, and urged away from the electromagnet by a spring that is weaker than the electromagnet. When the power supply to the lock is intentionally or unintentionally cut off, the spring thus urges the motor, and with it the bolt, away from the electromagnet, thereby automatically opening the lock.

Description

La présente invention concerne le domaine du contrôle d'accès à des locaux, en particulier de banques, ou analogues, équipés de portes ou de sas munis de dispositifs de verrouillage commandés au moyen de dispositifs électriques ou électroniques, et a pour objet une serrure électrique, notamment pour porte d'accès à des locaux sécurisés.The present invention relates to the field of access control to premises, in particular banks, or the like, equipped with doors or airlocks provided with locking devices controlled by means of electric or electronic devices, and has for its object an electric lock. , especially for access doors to secure premises.

Actuellement la sécurité de tels locaux est généralement assurée au moyen de portes équipées de gâches ou de serrures électriques commandées électriquement ou par un appareillage électronique autorisant ou interdisant l'entrée. Un tel équipement peut être monté directement sur de simples portes existantes, mais il a également été prévu de réaliser des ensembles qui offrent une plus grande sécurité et qui comportent deux portes asservies électriquement afin que leur ouverture simultanée ne puisse s'effectuer. Ces ensembles sont couramment appelés "sas asservis".Currently, the security of such premises is generally ensured by means of doors fitted with electric strikes or locks or by electronic equipment authorizing or prohibiting entry. Such equipment can be mounted directly on simple existing doors, but it has also been planned to produce assemblies which offer greater security and which include two electrically controlled doors so that their simultaneous opening cannot be effected. These sets are commonly called "slave airlocks".

Ces dispositifs connus nécessitent desverrouil- lages de porte à commande électrique et comportent des gâches ou serrures électriques, qui ne présentent cependant pas une bonne souplesse d'utilisation, et dont la sécurité peut être insuffisante. En outre, leur installation sur des portes existantes est délicate, voire impossible à réaliser.These known devices require electrically operated door locks and include electric strikes or locks, which however do not have good flexibility of use, and whose security may be insufficient. In addition, their installation on existing doors is tricky, if not impossible to achieve.

L'utilisation de gâches électriques entraîne certains inconvénients, à savoir, une surface d'emprise du pêne dans la gâche souvent trop faible pour assurer un verrouillage solide, cette surface étant parfois sérieusement diminuée en cas d'affaissement de la porte. En outre, une telle gâche est autobloquante, de sorte que sa libération n'est pas possible si une personne pousse sur la porte simultanément à la délivrance de l'autorisation électrique. Enfin, les portes équipées de ces gâches nécessitent des ferme-portes développant une force importante, en particulier dans le cas de portes de sécurité d'un poids élevé, afin d'assurer un bon enclenchement du pêne dans la gâche lors de la fermeture, de sorte que la manoeuvre des portes ainsi équipées occasionne une gêne pour les personnes âgées et les enfants.The use of electric strikes leads to certain drawbacks, namely, a surface area for the bolt in the strike often too small to ensure solid locking, this surface sometimes being seriously reduced in the event of the door sagging. In addition, such a keeper is self-locking, so that its release is not possible if a person pushes on the door simultaneously with the issuance of the electrical authorization. Finally, doors equipped with these strikes require door closers developing a significant force, in particular in the case of safety doors of high weight, in order to ensure good engagement of the bolt in the strike when closing, so that the operation of the doors thus equipped causes discomfort for the elderly and children.

Les serrures électriques existantes présentent également certains défauts obérant gravement leur capacité à réaliser une fermeture sûre. En effet, soit elles présentent un encombrement important empêchant leur incorporation dans des huisseries métalliques, soit leur montage sur des portes existantes est difficile, voire impossible, soit elles sont autobloquantes. En outre, du fait que la sécurité de verrouillage est pratiquement toujours réalisée au moyen d'électro-aimants, une porte incomplètement fermée à cause du vent, du ferme-porte, d'une petite inclusion, ou d'une légère déformation du cadre, est impossible à verrouiller du fait que lesdits électro-aimants présentent une course et une force limitées et ne peuvent donc assurer simultanément le parachèvement de la fermeture et le verrouillage.Existing electric locks also have certain faults seriously affecting their ability to achieve secure closure. Indeed, either they have a large size preventing their incorporation into metal frames, or their mounting on existing doors is difficult, if not impossible, or they are self-locking. In addition, since the locking security is almost always achieved by means of electromagnets, a door that is not fully closed due to the wind, the door closer, a small inclusion, or a slight deformation of the frame , is impossible to lock due to the fact that said electromagnets have a limited stroke and force and cannot therefore simultaneously complete the closure and the locking.

La présente invention a pour but de pallier ces inconvénients.The present invention aims to overcome these drawbacks.

Elle a, en effet, pour objet une serrure électrique, notamment pour porte d'accès à des locaux sécurisés, caractérisée en ce qu'elle est essentiellement constituée par un bloc compact comportant un pêne mobile motorisé et pouvant être monté en applique sur les traverses supérieures des portes existantes, et par une gâche largement dimensionnée, destinée à être montée en applique sur l'ouvrant des portes et comportant un cône d'introduction pour le parachèvement de la fermeture de la porte et une chape profonde prolongeant ledit cône et assurant le verrouillage final.Its purpose is in fact an electric lock, in particular for an access door to secure premises, characterized in that it is essentially constituted by a compact block comprising a motorized movable bolt and which can be mounted on the crossbeams superior existing doors, and by a large-sized keeper, intended to be mounted on the door leaf and comprising an introduction cone for completing the closing of the door and a deep clevis extending said cone and ensuring locking final.

L'invention sera mieux comprise grâce à la description ci-après, qui se rapporte à un mode de réalisation préféré, donné à titre d'exemple non limitatif, et expliqué avec référence aux dessins schématiques annexés, dans lesquels :

  • la figure 1 est une vue en perspective de la serrure conforme à l'invention ;
  • la figure 2 est une vue de détail du bloc compact comportant le pêne ;
  • la figure 3 est une vue en perspective d'une porte équipée d'une serrure conforme à l'invention, et
  • la figure 4 est une vue en plan et en coupe de la porte.
The invention will be better understood thanks to the description below, which relates to a preferred embodiment, given by way of nonlimiting example, and explained with reference to the appended schematic drawings, in which:
  • Figure 1 is a perspective view of the lock according to the invention;
  • Figure 2 is a detail view of the compact block comprising the bolt;
  • FIG. 3 is a perspective view of a door fitted with a lock according to the invention, and
  • Figure 4 is a plan view in section of the door.

Conformément à l'invention, et comme le montre plus particulièrement, à titre d'exemple, la figure 1 des dessins annexés, la serrure électrique, notamment pour porte d'accès à des locaux sécurisés, est essentiellement constituée par un bloc compact 1 qui comporte un pêne mobile 2 motorisé et qui peut être monté en applique sur les traverses supérieures des portes existantes, et par une gâche 3 largement dimensionnée, destinée à être montée en applique sur l'ouvrant des portes et qui comporte un cône d'introduction 4 permettant le parachèvement de la fermeture et une chape profonde 5 qui prolonge ledit cône 4 et assure le verrouillage final de la porte.According to the invention, and as shown more particularly, by way of example, Figure 1 of the accompanying drawings, the electric lock, in particular for access door to secure premises, is essentially constituted by a compact block 1 which comprises a movable bolt 2 motorized and which can be mounted as a surface on the upper crosspieces of existing doors, and by a striker 3 largely dimensioned, intended to be mounted as a surface on the opening of the doors and which comprises an insertion cone 4 allowing the completion of the closure and a deep yoke 5 which extends said cone 4 and ensures the final locking of the door.

Le bloc compact 1 est habillé d'un capot de protection 6 muni d'une ouverture de passage (non représentée) de l'axe du pêne 2, qui est mobile en translation horizontale, et qui se présente sous forme d'un doigt en saillie sous le bloc 1, et dont l'extrémité libre est pourvue d'un galet 7 monté sur roulement. Ce mode de réalisation du pêne 2 permet de faciliter son déplacement, même sous une forte poussée.The compact block 1 is covered with a protective cover 6 provided with a passage opening (not shown) of the bolt axis 2, which is movable in horizontal translation, and which is in the form of a finger in protruding under the block 1, and the free end of which is provided with a roller 7 mounted on a bearing. This embodiment of the bolt 2 makes it possible to facilitate its movement, even under a strong thrust.

Le cône d'introduction 4 et la chape profonde 5 de la gâche 3 s'étendent respectivement sur des zones de longueur a et b de la gâche 3, qui est munie, en outre, de trous 8 de fixation sur l'ouvrant de la porte.The introduction cone 4 and the deep cap 5 of the keeper 3 extend respectively over areas of length a and b of the keeper 3, which is further provided with holes 8 for fixing on the door leaf.

L'actionnement du pêne 2 est réalisé au moyen d'un motoréducteur 9 agissant, par l'intermédiaire d'une tige filetée 10, sur un axe 11 solidaire du pêne 2 et guidé en translation dans un palier 12, la course du pêne étant réglée au moyen de butées de fin de course 13 montées sur le palier 12 et coopérant avec un ergot 14 solidaire de l'axe 11 (figure 2). Ce motoréducteur 9 permet d'assurer le parachèvement de la fermeture de la porte par introduction du galet 7 du pêne 2 sur la zone de longueur a du cône 4 de la gâche 3, puis le verrouillage final sur la zone de longueur b de la chape profonde 5.The bolt 2 is actuated by means of a geared motor 9 acting, via a threaded rod 10, on an axis 11 secured to the bolt 2 and guided in translation in a bearing 12, the stroke of the bolt being adjusted by means of end-of-travel stops 13 mounted on the bearing 12 and cooperating with a lug 14 integral with the axis 11 (Figure 2). This geared motor 9 ensures the completion of the closing of the door by introduction of the roller 7 of the bolt 2 on the zone of length a of the cone 4 of the keeper 3, then the final locking on the zone of length b of the yoke deep 5.

Le motoréducteur 9 est monté coulissant sur le bloc 1 au moyen d'un guidage 15 et est bridé en position de travail par un électro-aimant 16 contre l'action d'un ressort de rappel 17 fixé sur le motoréducteur 9 au moyen d'un axe 18 et solidaire du bloc 1 par l'intermédiaire d'un axe 19, ce ressort de rappel 17 amenant le motoréducteur 9, ensemble avec le pêne 2, en dehors des zones d'introduction a et de verrouillage b de la gâche 3 lors d'une coupure de l'alimentation de l'électro-aimant 16.The gear motor 9 is slidably mounted on the block 1 by means of a guide 15 and is clamped in the working position by an electromagnet 16 against the action of a return spring 17 fixed on the gear motor 9 by means of an axis 18 and integral with the block 1 via an axis 19, this return spring 17 bringing the gearmotor 9, together with the bolt 2, outside of the introduction a and locking zones b of the keeper 3 when the electromagnet 16 is cut off.

En effet, dans le cas d'une telle coupure de l'alimentation de l'électro-aimant 16, ce dernier libère le motoréducteur 9, qui est déplacé, ensemble avec le pêne 2 en position de déverrouillage. Ce mode de réalisation permet, notamment, une libération de porte quasi-instantanée conformément aux règles de sécurité incendie.Indeed, in the case of such a cut in the supply of the electromagnet 16, the latter releases the geared motor 9, which is moved, together with the bolt 2 in the unlocked position. This embodiment allows, in particular, almost instantaneous door release in accordance with fire safety rules.

La commande du motoréducteur 9 est effectuée par un circuit électronique de gestion 20 monté dans le bloc 1 et actionné par un interrupteur à lame souple 21, également monté dans le bloc 1, et qui coopère en position de parachèvement de fermeture et de verrouillage avec un aimant 22 monté sur la gâche 3. Ainsi, dans la position précitée, l'aimant 22 attire la lame de l'interrupteur 21, dont le contact est alors fermé, et qui actionne le circuit électronique de gestion 20, qui délivre une impulsion de commande du motoréducteur 9 dans le sens d'une fermeture et d'un verrouillage de la porte.The gear motor 9 is controlled by an electronic management circuit 20 mounted in the block 1 and actuated by a flexible blade switch 21, also mounted in the block 1, and which cooperates in the closing and locking finishing position with a magnet 22 mounted on the keeper 3. Thus, in the aforementioned position, the magnet 22 attracts the blade of the switch 21, the contact of which is then closed, and which actuates the electronic management circuit 20, which delivers a pulse of ordered of the gear motor 9 in the direction of closing and locking the door.

Conformément à une autre caractéristique de l'invention, et comme le montre la figure 3, le circuit électrique d'alimentation de l'électro-aimant 16 de maintien en position de travail du motoréducteur 9 est branché en série avec les contacts électriques d'un barillet 23 à contact incorporé normalement fermé, dont l'ouverture peut être effectuée par introduction et rotation d'une clé 24. Ainsi, l'introduction de la clé 24 dans le barillet 23 a pour effet de couper l'alimentation de l'électro-aimant 16, de sorte que le motoréducteur 9 et le pêne 2 sont amenés en position déverrouillée.In accordance with another characteristic of the invention, and as shown in FIG. 3, the electrical supply circuit of the electromagnet 16 for maintaining the working position of the gearmotor 9 is connected in series with the electrical contacts of a barrel 23 with incorporated contact normally closed, the opening of which can be effected by introduction and rotation of a key 24. Thus, the introduction of the key 24 into the barrel 23 has the effect of cutting off the supply of the electromagnet 16, so that the gearmotor 9 and the bolt 2 are brought into the unlocked position.

Selon une autre caractéristique de l'invention, et comme le montre la figure 4, la serrure est combinée avec une baguette verticale 25 fixée sur le bâti 26 de la porte du côté opposé aux gonds 27 et s'étendant sur toute la hauteur dudit châssis, l'épaisseur de cette baguette 25 étant au moins égale à l'espace 28 correspondant à l'ouverture à partir de laquelle le galet 7 du pêne 2 s'enclenche dans le cône 4 de la gâche 3.According to another characteristic of the invention, and as shown in FIG. 4, the lock is combined with a vertical strip 25 fixed on the frame 26 of the door on the side opposite the hinges 27 and extending over the entire height of said chassis , the thickness of this rod 25 being at least equal to the space 28 corresponding to the opening from which the roller 7 of the bolt 2 engages in the cone 4 of the keeper 3.

Cette baguette 25 permet donc de fermer totalement l'espace 28, de sorte qu'il est impossible d'y passer les doigts, même des doigts d'enfants; et que des blessures graves sont évitées lors de la fermeture par la serrure électrique.This rod 25 therefore makes it possible to completely close the space 28, so that it is impossible to pass the fingers through it, even the fingers of children; and that serious injuries are avoided when closing with the electric lock.

Grâce à l'invention, il est possible de réaliser des serrures électriques pour portes d'accès à des locaux sécurisés offrant une sécurité de fonctionnement totale et permettant un parachèvement de la fermeture ainsi qu'un verrouillage final.Thanks to the invention, it is possible to produce electric locks for access doors to secure premises offering total operating security and allowing completion of the closure as well as final locking.

Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté aux dessins annexés. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments, ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.Of course, the invention is not limited to the embodiment described and shown in the accompanying drawings. Modifications remain possible, in particular from the point of view of the constitution of the various elements, or by substitution of technical equivalents, without thereby departing from the scope of protection of the invention.
