Abstract
Description
La présente invention a pour objet un dispositif de serrure à profil étroit, à manoeuvrement soit électrique soit mécanique selon le préambule de la revendication 1.The present invention relates to a lock device with a narrow profile, with either electrical or mechanical operation according to the preamble of
On connaît déjà des dispositifs de serrures manoeuvrables soit électriquement, soit mécaniquement, destinés à équiper des portes dont l'ouverture et la fermeture doivent pouvoir être réalisées non seulement au moyen d'une commande à combinaison ou d'une télécommande électronique, mais également au moyen d'une clé de sûreté, notamment en cas de panne de courant.Locking devices which are operable either electrically or mechanically are already known, intended to equip doors whose opening and closing must be capable of being carried out not only by means of a combination control or an electronic remote control, but also at using a safety key, especially in the event of a power failure.
Toutefois ces serrures, du fait de la présence des deux mécanismes de rentrée et de sortie du pêne, ne peuvent pas toujours être implantées dans une porte au profil étroit, et ceci d'autant plus qu'il doit être également possible de manoeuvrer la serrure électriquement après que celle-ci ait été manoeuvrée mécaniquement, ou inversement, ce qui complique son architecture.However, these locks, due to the presence of the two mechanisms for re-entry and exit of the bolt, cannot always be installed in a door with a narrow profile, and this all the more so since it must also be possible to operate the lock. electrically after it has been mechanically operated, or vice versa, which complicates its architecture.
D'autre part les mécanismes électriques de ces dispositifs font appel, entre le moteur électrique et le pêne, à une transmission alliant pignons et leviers, cause d'une perte de force de sortie du pêne, préjudiciable au bon fonctionnement du dispositif, en sorte qu'il est parfois nécessaire, au moment du verrouillage, que le pêne force l'accès dans la gâche quand il n'est pas exactement en regard de ladite gâche.On the other hand, the electrical mechanisms of these devices use, between the electric motor and the bolt, a transmission combining pinions and levers, cause of a loss of output force of the bolt, detrimental to the proper functioning of the device, so that it is sometimes necessary, when locking, that the bolt forces access into the strike when it is not not exactly opposite said strike.
Un dispositif de serrure à manoeuvrement soit électrique soit mécanique, qui ne comporte pas de levier, est montré par le document DE-A-3 825 909.An electrically or mechanically operated lock device which does not include a lever is shown in document DE-A-3 825 909.
La présente invention vise à remédier à ces inconvénients en proposant un dispositif de serrure à manoeuvrement soit électrique soit mécanique, sans qu'aucun des deux mécanismes ne soit prioritaire par rapport à l'autre, d'architecture simple, pouvant s'intégrer parfaitement dans une porte à profil étroit, et présentant de surcroît l'avantage, en ce qui concerne son manoeuvrement électrique, d'une force d'extraction du pêne supérieure à celle des dispositifs existants.The present invention seeks to remedy these drawbacks by proposing a lock device for maneuvering either electric or mechanical, without either of the two mechanisms taking priority over the other, of simple architecture, which can be perfectly integrated into a door with a narrow profile, and moreover having the advantage, with regard to its electrical operation, of a force of extraction of the bolt greater than that of the existing devices.
En accord avec la présente invention, cet objectif est obtenu par un dispositif selon la revendication 1.In accordance with the present invention, this objective is obtained by a device according to
Le dispositif de serrure objet de la présente invention comporte de préférence un pêne monté coulissant sur deux axes parallèles solidaires d'une platine.The lock device object of the present invention preferably comprises a bolt slidably mounted on two parallel axes secured to a plate.
La couronne comporte de préférence un pignon engrené sur la crémaillère d'une coulisse pouvant se déplacer longitudinalement sur la platine, perpendiculairement au déplacement du pêne, ce déplacement étant réalisé soit mécaniquement au moyen d'une clé, soit électriquement.The crown preferably comprises a pinion meshed on the rack of a slide which can move longitudinally on the plate, perpendicular to the movement of the bolt, this movement being carried out either mechanically by means of a key, or electrically.
Selon un mode de réalisation avantageux, mécaniquement, la rotation d'une clé entraîne la rotation d'une lanterne qui comporte deux tétons diamétralement opposés dont l'un vient prendre appui sur l'un des deux piliers que comporte la coulisse, selon qu'il s'agisse de rentrer ou de sortir le pêne.According to an advantageous embodiment, mechanically, the rotation of a key causes the rotation of a lantern which comprises two diametrically opposed studs, one of which comes to bear on one of the two pillars that comprises the slide, depending on whether it involves entering or removing the bolt.
Selon un mode de réalisation avantageux, électriquement, un motoréducteur d'axe parallèle à l'axe de déplacement du pêne, entraîne un ensemble de pignons réducteurs qui s'engrène sur une seconde crémaillère solidaire de la coulisse. Deux capteurs optiques infrarouges permettent de détecter la position en fin de course de la coulisse, dont une partie selon sa position vient couper l'un ou l'autre des faisceaux infrarouges émis par lesdits capteurs.According to an advantageous embodiment, electrically, a geared motor with an axis parallel to the axis of movement of the bolt, drives a set of reducing pinions which meshes on a second rack integral with the backstage. Two infrared optical sensors make it possible to detect the position at the end of the travel of the slide, part of which according to its position cuts one or the other of the infrared beams emitted by said sensors.
De préférence, la position du motoréducteur, d'axe parallèle à l'axe de déplacement du pêne, permet de réaliser une serrure d'une très faible épaisseur facilement intégrable dans une porte de profil étroit.Preferably, the position of the geared motor, with an axis parallel to the axis of movement of the bolt, makes it possible to produce a lock of very small thickness which can easily be integrated into a door of narrow profile.
De plus le fait que, de préférence, la transmission du mouvement du motoréducteur à la coulisse soit assurée uniquement par des pignons confère à la serrure selon l'invention une force d'extraction du pêne supérieure à celle des dispositifs existants qui utilisent des pignons et des leviers.Furthermore, the fact that, preferably, the transmission of the movement of the gearmotor to the slide is ensured solely by pinions gives the lock according to the invention a force of extraction of the bolt greater than that of existing devices which use pinions and levers.
Selon un mode de réalisation avantageux le pêne peut comporter un rouleau facilitant son introduction dans la gâche.According to an advantageous embodiment, the bolt may include a roller facilitating its introduction into the keeper.
Les avantages et les caractéristiques de la présente invention ressortiront plus clairement de la description qui suit et qui se rapporte au dessin annexé, lequel en représente un mode de réalisation non limitatif.The advantages and characteristics of the present invention will emerge more clearly from the description which follows and which refers to the appended drawing, which represents a non-limiting embodiment thereof.
Dans le dessin annexé ;
- la figure 1 représente une vue partielle en plan d'un dispositif de serrure selon l'invention, dans lequel le pêne est sorti.
- la figure 2 représente le même dispositif dans lequel le pêne est rentré.
- Figure 1 shows a partial plan view of a lock device according to the invention, in which the bolt is released.
- Figure 2 shows the same device in which the bolt is returned.
Si on se réfère à ces figures on peut voir que le dispositif de serrure selon l'invention comporte une platine 1 à laquelle est solidarisée latéralement une têtière 10 traversée par un pêne 2 à rouleau 23, monté coulissant sur deux axes 22 solidaires de la platine 1, qui le pénètrent.If we refer to these figures we can see that the lock device according to the invention comprises a
Le pêne 2 comporte une queue de pêne 20 où est ménagée une encoche 21, disposée parallèlement à la têtière 10, et dans laquelle s'inscrit le galet fou excentré 30 d'une couronne 3 montée sur un axe 11 solidaire de la platine 1.The
La couronne 3 comporte, sur sa face opposée à celle comportant le galet 30, un pignon 32, traversé par l'axe 11, qui s'engrène sur la crémaillère 41 d'une coulisse 4 apte à se déplacer parallèlement à la têtière 10, et maintenue par des piliers épaulés 12 enfilés dans des orifices oblongs 40 pratiqués dans la coulisse 4.The
L'extrémité inférieure de la coulisse 4 comporte deux piliers entraîneurs 43 et 44 alignés parallèlement à la têtière 10. Une lanterne 5, munie de deux tétons 50 et 51, montée pivotante sur la platine 1 en regard d'un canon de clé, non représenté, est positionnée de telle manière que, lors de sa rotation, l'un des tétons 50 et 51, selon le sens de rotation, puisse prendre appui, selon la position de la coulisse 4, sur l'un ou l'autre des piliers entraîneurs 43 et 44 afin d'entraîner la coulisse 4 en déplacement.The lower end of the
La coulisse 4 comporte sur sa face supérieure une seconde crémaillère 42 sur laquelle s'engrène un ensemble 6 de pignons réducteurs d'axes parallèles au déplacement du pêne 2, entraîné par un motoréducteur 60.The
Le motoréducteur 60 est connecté à une carte électronique 63 qui comporte deux capteurs optiques infrarouges 61 et 62 alignés parallèlement à la têtière 10, et distants de la longueur de déplacement de la coulisse 4, laquelle comporte un prolongement 45 qui selon les positions extrêmes de déplacement coupe les faisceaux de l'un ou l'autre des capteurs optiques 61 et 62.The
Le dispositif de serrure selon l'invention fonctionne de la manière décrite ci-après selon différents cas de figure.The lock device according to the invention operates in the manner described below according to different cases.
Une fois la serrure verrouillée, le pêne sorti (figure 1) pour la déverrouiller électriquement il suffit, au moyen d'un dispositif de commande approprié, de déclencher la rotation du motoréducteur 60 qui, par l'intermédiaire de l'ensemble 6 de pignons réducteurs et de la crémaillère 42 provoque le déplacement de la coulisse 4, qui entraîne, par l'intermédiaire de la crémaillère 41 et du pignon 32, la rotation de la couronne 3 dont le galet excentré 30 entraîne le pêne 2, qui s'escamote. Il est à noter que le fonctionnement électrique est complètement indépendant du fonctionnement mécanique, puisque le déplacement électrique de la coulisse 4 n'engendre aucun pivotement de la lanterne 5.Once the lock is locked, the bolt extended (Figure 1) to unlock it electrically, it is enough, by means of an appropriate control device, to trigger the rotation of the
Pour déverrouiller mécaniquement la serrure, il suffit, au moyen d'une clé de sûreté engagée dans le canon à clé, non représenté, de faire tourner la lanterne 5 dans le sens horaire selon la figure 1, de manière que le téton 50 vienne prendre appui sur le pilier entraîneur 43 et ainsi entraîne en déplacement la coulisse 4.To mechanically unlock the lock, it suffices, by means of a safety key engaged in the key barrel, not shown, to rotate the
Que le déverrouillage se fasse électriquement ou mécaniquement, la carte électronique 63 "connaît" la position du pêne 2, le prolongement 45 de la coulisse 4 étant alors en regard du capteur optique 62.Whether the unlocking is done electrically or mechanically, the
Le verrouillage de la serrure s'effectue de la manière inverse, à savoir qu'électriquement le moteur tourne dans le sens inverse, et que mécaniquement la rotation dans le sens horaire inversé de la lanterne 5 a pour conséquence l'appui du téton 51 sur le pilier entraîneur 44.The locking of the lock is carried out in the opposite way, namely that electrically the motor turns in the opposite direction, and that mechanically the rotation in the clockwise direction reversed of the
