Abstract

Latch for equipping opening panels of industrial installations of the type comprising a latch body which moves between a protruding active position in which a protruding part, called a nose-piece, is adapted to come to a stop against a support edge, and a withdrawn position in which the nose-piece is disengaged from the support edge, this body being elastically returned to the active position, characterised by an articulated mounting of the nose-piece 21 allowing the latter, in the active position of the latch body 19, to become retracted in contact with the support edge 27 during the closing movement against the action of a return spring 18.

Description

Loquet à bec articulé à claquer"
La présente invention concerne les loquets destinés à équiper des portes ou panneaux ouvrants d'installations industrielles, notamment de portes d'armoires électriques ou analogues.
Hinged spout latch "
The present invention relates to latches intended to equip doors or opening panels of industrial installations, in particular of doors of electrical cabinets or the like.

L'emploi de loquets tournants ou coulissants est très largement répandu. Ces loquets ont l'avantage d'être d'une réalisation et d'une utilisation simples. Cependant les portes, ou autres panneaux ouvrants équipés de ces loquets présentent l'inconvénient de ne pouvoir se fermer en les cla- quant. Il est en effet nécessaire à chaque fois de manoeuvrer le loquet, et ceci est une perte de temps lorsque ce genre de manoeuvres doit se répéter souvent. Or dans certaines applications le problème s'est posé de répondre à un impératif de sécurité suivant lequel la porte d'une armoire laissée par mégarde ouverte (oubli de refermer, pas de clé...) doit pouvoir être fermée, simplement en claquant la porte, par n'importe quelle personne de passage. The use of rotary or sliding latches is very widespread. These latches have the advantage of being simple to make and use. However, the doors or other opening panels fitted with these latches have the drawback of not being able to close by slamming them. It is indeed necessary each time to operate the latch, and this is a waste of time when this type of operation must be repeated often. However, in some applications the problem arose of responding to a security imperative according to which the door of a cabinet inadvertently left open (forgetting to close, no key ...) must be able to be closed, simply by slamming the door, by any person passing through.

La présente invention cherche à répondre à ce problème en créant un loquet à bec articulé, effaçable rendant possible la fermeture d'un panneau ouvrant en claquant
A cet effet, le but de l'invention est de créer un loquet du genre comportant un corps de loquet mobile entre une position active saillante où une partie saillante, dite bec, est adaptée à venir en butée sur un bord d'appui et une position en retrait où le bec est dégagé du bord d'appui, ce corps étant rappelé élastiquement en position active, caractérisé par un montage articulé du bec permettant à celui-ci, en position active du corps de loquet, de swesca- moter au cours des mouvements de fermeture, au contact du bord d'appui, à l'encontre d'un ressort de rappel.
The present invention seeks to respond to this problem by creating an articulated, erasable spout latch making it possible to close an opening panel by snapping
To this end, the object of the invention is to create a latch of the type comprising a movable latch body between an active projecting position where a projecting part, called spout, is adapted to come into abutment on a bearing edge and a recessed position where the spout is released from the support edge, this body being resiliently recalled in the active position, characterized by an articulated mounting of the spout allowing the latter, in the active position of the latch body, to swesca- motor during closing movements, in contact with the bearing edge, against a return spring.

D'autres caractéristiques et avantages de l'invention ressortiront d'ailleurs de la description qui va suivre donnée à titre d'exemple en référence aux dessins annexés dans lesquels
la figure 1 représente une vue en perspective écla- tée d'un loquet à bec articule à claquer, ce loquet étant ici de type tournant ;

Suivant la forme de réalisation choisie et représen- tee, un loquet 10 est constitué d'un verrou Il comportant une entrée 12, un stator 13, un rotor 14. Le stator 13 est un corps cylindrique comportant un filetage et deux méplats. Le rotor 14 est un corps cylindrique adapté à tourner dans le stator et présentant une partie saillante filetée avec quatre méplats répartis sur la périphérie. Sur le stator viennent se fixer, un panneau ouvrant 15 comportant un trou oblong de blocage en rotation sur le stator, une plaquette 16 comportant un trou de forme semblable également emboîtable sur le stator et un écrou 17 adapté à se visser sur le stator pour fixation de pièces 15 et 16. Un corps de loquet 19 comportant un trou de blocage en rotation par rapport au rotor est enfilé sur le rotor et un écrou 22 est adapté à s'y visser pour sa fixation sur le rotor.Le corps de loquet 19 comporte une aile deux fois recourbée à angles droits et formant à son extrémité un palier 23 pour un axe d'articulation 20, sur lequel s'articule un bec de loquet 21 en forme de chape. According to the embodiment chosen and shown, a latch 10 consists of a latch II comprising an inlet 12, a stator 13, a rotor 14. The stator 13 is a cylindrical body comprising a thread and two flats. The rotor 14 is a cylindrical body adapted to rotate in the stator and having a threaded projecting part with four flats distributed over the periphery. On the stator are fixed, an opening panel 15 comprising an oblong hole for locking in rotation on the stator, a plate 16 comprising a similarly shaped hole also nestable on the stator and a nut 17 adapted to be screwed on the stator for fixing. of parts 15 and 16. A latch body 19 comprising a hole for locking in rotation with respect to the rotor is threaded onto the rotor and a nut 22 is adapted to be screwed therein for its attachment to the rotor. The latch body 19 comprises a wing twice bent at right angles and forming at its end a bearing 23 for an axis of articulation 20, on which is articulated a latch spout 21 in the form of a yoke.

L'axe d'articulation 20 est, en position de fermeture, parallèle à l'axe de rotation-du panneau ouvrant.The articulation axis 20 is, in the closed position, parallel to the axis of rotation of the opening panel.

Un ressort à boudin 18 est accroché, d'une part, à un point fixe 24 de la plaquette 16, et d'autre part, à un autre point d'accrochage 25 appartenant au bec de loquet 21.  A coil spring 18 is hooked, on the one hand, to a fixed point 24 of the plate 16, and on the other hand, to another attachment point 25 belonging to the latch spout 21.

Les pièces précitées sont de préférence métalliques. The aforementioned parts are preferably metallic.

Le verrou 10 peut être de différents types par exemple à empreintes, à combinaisons, à ailettes.The latch 10 can be of different types, for example fingerprints, combinations, fins.

Le verrou monté sur un panneau ouvrant 15 assure la fermeture de celui-ci, sur un panneau fixe 26 comportant un épaulement 27, servant de surface d'appui au bec de loquet 21. Le panneau ouvrant porte un joint d'étanchéité 28 destiné à venir en appui contre le rebord 29 de l'épaulement 27 du panneau fixe 26, lors de la fermeture du panneau ouvrant. The lock mounted on an opening panel 15 ensures the closing thereof, on a fixed panel 26 having a shoulder 27, serving as a bearing surface for the latch spout 21. The opening panel carries a seal 28 intended for come to bear against the rim 29 of the shoulder 27 of the fixed panel 26, when the opening panel is closed.

La fermeture du panneau ouvrant s'effectue de la façon suivante. Le panneau ouvrant est poussé (figure 2a) suivant le sens de la flèche A. L'extrémité 30 du bec de loquet entre alors en contact avec le rebord 29 du panneau fixe. Le bec de loquet est repoussé suivant la flèche B, par le rebord 29. Le ressort 18 est alors sollicite en extension. The opening panel is closed as follows. The opening panel is pushed (Figure 2a) in the direction of arrow A. The end 30 of the latch spout then comes into contact with the flange 29 of the fixed panel. The latch spout is pushed back along arrow B, by the flange 29. The spring 18 is then urged in extension.

En raison de l'inertie donnée par la force s'exerçant selon la flèche A (figure 2b), le panneau ouvrant continue à se rapprocher du panneau fixe, l'extrémité 30 du bec de loquet étant en contact avec le rebord 29 du panneau fixe 26, ceci jusqu'à ce que l'extrémité 30 du bec de loquet dépasse i 'é- paulement 27 du panneau fixe (figure 2c). Le bec de loquet se déplace alors selon le sens de la flèche D sous l'action du ressort 18 qui revient ainsi à sa position d'équilibre
Le panneau ouvrant est alors en position de fermeture.
Due to the inertia given by the force exerted according to arrow A (FIG. 2b), the opening panel continues to approach the fixed panel, the end 30 of the latch spout being in contact with the flange 29 of the panel. fixed 26, this until the end 30 of the latch spout exceeds the shoulder 27 of the fixed panel (Figure 2c). The latch spout then moves in the direction of the arrow D under the action of the spring 18 which thus returns to its equilibrium position
The opening panel is then in the closed position.

L'ouverture du panneau ouvrant est réalisée comme pour tout loquet tournant. A l'aide d'un moyen quelconque (clef à empreintes, combinaison, bouton, etc.), le rotor du verrou est tourné de 90" environ selon la flèche E (figure 2c). I1 en résulte (figure 3) que le bec de loquet se dégage de l'épaulement 27 du panneau fixe, le ressort 18 étant sollicité en extension. En exerçant sur le panneau ouvrant une force selon la flèche F, le bord 31 du bec de loquet se pla çant en regard du rebord 29 le loquet se dégage, après quoi le corps de loquet, une fois relâché, est rappelé en sa position de repos de la figure 2a, sous l'action du ressort 18.  The opening of the opening panel is carried out as for any rotary latch. Using any means (fingerprint key, combination, button, etc.), the rotor of the lock is rotated by approximately 90 "according to arrow E (Figure 2c). As a result (Figure 3) latch spout emerges from the shoulder 27 of the fixed panel, the spring 18 being biased in extension, exerting on the panel opening a force according to arrow F, the edge 31 of the latch spout being placed opposite the flange 29 the latch is released, after which the latch body, once released, is returned to its rest position in FIG. 2a, under the action of the spring 18.

Le loquet est alors prêt pour une nouvelle fermeture éventuelle du panneau ouvrant. I1 est à noter que lors de la fermeture le verrou 11 peut être verrouillé ou non, cela n'a aucune incidence sur le fonctionnement du bec de loquet. Le loquet peut être utilisé d'une façon traditionnelle, c' est-à- dire en manoeuvre rotative, le déverrouillage s'effectuant également de manière traditionnelle. The latch is then ready for possible closing of the opening panel. I1 should be noted that when closing the latch 11 can be locked or not, this has no effect on the operation of the latch spout. The latch can be used in a traditional way, that is to say in rotary operation, the unlocking also taking place in the traditional way.

I1 est possible de réaliser le corps de loquet 19a, 19b de diverses manières. Ainsi la figure 4 montre un bec moulé 21a emboité entre les deux branches d'un corps de loquet 19a formant chape. La figure 5 montre un corps de loquet 19b semblable à celui de la figure 1 mais où le palier de l'axe d'articulation se réduit à deux ailettes percées. It is possible to produce the latch body 19a, 19b in various ways. Thus Figure 4 shows a molded spout 21a fitted between the two branches of a latch body 19a forming a yoke. Figure 5 shows a latch body 19b similar to that of Figure 1 but where the bearing of the hinge pin is reduced to two pierced fins.

Bien entendu l'invention n'est pas limitée aux modes de réalisation choisis et représentés, on peut notamment l'appliquer à des loquets coulissants et non plus tournants.  Of course, the invention is not limited to the embodiments chosen and shown, it can in particular be applied to sliding latches and no longer rotating.
