Description

La présente invention concerne une serrure pour porte à sécurité positive et double empennage notamment pour porte palière d'appareils élévateurs.The present invention relates to a lock for a positive security door and double tail unit, in particular for a landing door of elevating devices.

Dans cette application particulière il est indispensable de respecter un certain nombre de normes qui sont édictées sous la référence NF P 82.201 Chapitre 2.137; 82 210; 82 211; 82 212, etc. auxquelles on pourra se reporter.In this particular application, it is essential to respect a certain number of standards which are enacted under the reference NF P 82.201 Chapter 2.137; 82,210; 82,211; 82 212, etc. to which we can refer.

Néanmoins, il est rappelé pour mémoire que dans une installation d'appareils élévateurs, la porte palière, pour un étage considéré, ne doit pouvoir s'ouvrir que lorsque la cabine est à l'étage.However, it is recalled that in an installation of elevating devices, the landing door, for a floor considered, should only be able to open when the cabin is upstairs.

De même, elle ne peut recevoir l'ordre de départ que si la porte palière est fermée et correctement fermée. Pour cela, il est connu d'utiliser une serrure à sécurité positive et à double empennage dont le fonctionnement sera rappelé en préambule de la description qui va suivre.Similarly, it can only receive the start order if the landing door is closed and correctly closed. For this, it is known to use a positive security lock with a double tail, the operation of which will be recalled in the preamble to the description which follows.

Ce type de serrure connue est constituée par:

  • un boîtier susceptible d'être fixé sur une huisserie de la porte palière,
  • un pène de verrouillage de la porte, disposé à coulissement dans le boîtier et sur lequel agit un ressort monté en compression, lequel pène est susceptible de coopérer en fermeture avec un percuteur fixe solidaire du vantail d'une porte battante ou coulissante agissant sur un dispositif de sécurité du pène et apte à n'autoriser la libération complète du pène en verrouillage, sous condition que la porte soit fermée,
  • un levier de commande du pène en liaison avec celui-ci et actionné en basculement autour d'un axe, de manière à provoquer une translation dudit pène en ouverture ou en fermeture,
  • un bras de manoeuvre du levier agissant directement sur son axe dans une position frontale au boîtier ou par un système de renvoi d'angle dans une position latérale au boîtier, lequel bras de manoeuvre est disposé sur le boîtier de telle sorte à pouvoir être actionné dans un plan frontal ou latéral par une came fixe ou mobile solidaire d'une cabine d'appareil élévateur,
  • un contact électrique de pène pour n'agir en fermeture que lorsque celui-ci est complètement libéré en verrouillage et autoriser dans cette position uniquement, le fonctionnement de l'ascenseur,
  • un contact électrique à arrachement dont un élément de court-circuitage est fixé sur le vantail de la porte de manière à n'autoriser le fonctionnement de la came de la cabine que si ladite porte est fermée,
This type of known lock consists of:
  • a housing capable of being fixed to a frame of the landing door,
  • a door locking bolt, arranged to slide in the housing and on which acts a spring mounted in compression, which bolt is capable of cooperating in closing with a fixed striker secured to the leaf of a hinged or sliding door acting on a device security of the bolt and suitable for not authorizing the complete release of the bolt when locking, provided that the door is closed,
  • a lever for controlling the bolt in connection with the latter and actuated in tilting around an axis, so as to cause a translation of said bolt in opening or closing,
  • a lever operating arm acting directly on its axis in a position frontal to the housing or by a bevel gear system in a position lateral to the housing, which operating arm is arranged on the housing so that it can be actuated in a frontal or lateral plane by a fixed or movable cam secured to a lifting device cabin,
  • an electrical bolt contact so as to act in closing only when the latter is completely released in locking mode and to authorize in this position only, the operation of the elevator,
  • an electric tear-off contact, a short-circuiting element of which is fixed on the door leaf so as to authorize the operation of the cabin cam only if said door is closed,

Ce type de serrure largement diffusée à ce jour dans le domaine d'application précité, même si donnant de bons résultats, présente l'inconvénient majeur de nécessiter une multiplicité très importante de modèles, afin de couvrir les besoins du marché, en fonction de tous les cas de figure rencontres.This type of lock widely distributed to date in the aforementioned field of application, even if giving good results, has the major drawback of requiring a very large multiplicity of models, in order to cover the needs of the market, depending on all the cases encountered.

En effet, chacun de ces cas conduit à une application particulière de la serrure, ce qui entraîne une conception spécifique de celle-ci. C'est le cas des serrures décrites dans les documents DE-B-1100897 et FR-A-916660.Indeed, each of these cases leads to a particular application of the lock, which leads to a specific design thereof. This is the case of the locks described in documents DE-B-1100897 and FR-A-916660.

A titre d'exemples non limitatifs il sera cité les cas les plus fréquemment rencontrés, à savoir:

  • sortie de pène à droite ou à gauche en fonction du sens d'ouverture de la porte,
  • longueur du pène différente selon la distance du montant de l'huisserie sur laquelle est fixée la serrure par rapport à la porte,
  • emplacement du contact de présence à arrachement à droite ou à gauche ou extérieur à la serrure,
  • positionnement du biseau de pène en fonction du sens d'ouverture de la porte et du type de fonctionnement: battante, coulissante, guillotine, etc.,
  • positionnement du levier de commande selon que le pène est à droite ou à gauche,
  • bras de manoeuvre externe, frontal ou latéral en fonction de la came de la cabine,
  • positionnement des contacts de pène et de présence.
By way of nonlimiting examples, the most frequently encountered cases will be cited, namely:
  • bolt outlet on the right or on the left depending on the direction of opening of the door,
  • length of the bolt different according to the distance of the amount of the frame on which the lock is fixed in relation to the door,
  • location of the tear-off presence contact on the right or left or outside the lock,
  • positioning of the bolt bevel according to the direction of opening of the door and the type of operation: casement, sliding, guillotine, etc.,
  • positioning of the control lever depending on whether the bolt is on the right or on the left,
  • external, front or side control arm depending on the cabin cam,
  • positioning of the bolt and presence contacts.

On comprend aisément qu'une telle diversité de serrures est très difficile à gérer tant au niveau du fabricant que de l'installateur.It is easy to understand that such a variety of locks is very difficult to manage both at the level of the manufacturer and of the installer.

En ce qui concerne ce dernier, non seulement il aura à supporter le surcoût provoquer par la limitation de production pour chaque type de serrure, mais de plus, il devra entretenir un stock important afin d'être en mesure de faire face à la demande immédiatement. Ce dernier point est également d'importance sur un plan financier car il entraîne un investissement lourd pour une répartition des stocks difficile à maîtriser.Regarding the latter, not only will he have to bear the additional cost caused by the production limitation for each type of lock, but moreover, he will have to maintain a large stock in order to be able to meet demand immediately . This last point is also of importance on a financial level because it involves a heavy investment for a distribution of stocks difficult to control.

En ce qui concerne le document FR-A 916660 celui-ci tend à remédier au problème posé en suggérant une serrure rendue universelle par inversion de certaines pièces mais il se limite à l'application à une serrure qui n'est pas à sécurité positive.With regard to document FR-A 916660, this tends to remedy the problem posed by suggesting a lock made universal by reversing certain parts, but it is limited to the application to a lock which is not positive security.

La présente invention a pour but de remédier à tous ces inconvénients et concerne à cet effet une serrure universelle pour porte à sécurité positive et double empennage notamment pour porte palière (6) d'appareils élévateurs du type constitué par:

  • un boitier susceptible d'être fixé sur une huisserie de la porte palière,
  • un pène de verrouillage de la porte disposé à coulissement dans le boîtier et sur lequel agit un ressort monté en compression, lequel pène est susceptible de coopérer en fermeture avec un percuteur fixe solidaire du vantail de la porte battante ou coulissante. agissant sur un dispositif de sécurité du pène et apte à n'autoriser la libération complète du pène en verrouillage, sous condition que la porte soit fermée,
  • un levier de commande du pène en liaison avec celui-ci et actionné en basculement autour d'un axe de manière à provoquer une translation dudit pène en ouverture ou en fermeture,
  • un bras de manoeuvre du levier agissant directement sur son axe dans une position frontale au boîtier ou par un système de renvoi d'angle dans une position latérale au boîtier, lequel bras de manoeuvre est disposé sur le boîtier de telle sorte à pouvoir être actionné dans un plan frontal ou latéral par une came fixe ou mobile solidaire d'une cabine d'appareils élévateurs,
  • un contact électrique de pène pour n'agir en fermeture que lorsque celui-ci est complètement libéré en verrouillage et autoriser dans cette position uniquement, le fonctionnement de l'appareil élévateur,
  • un contact électrique à arrachement dont un élément de court-circuitage est fixé sur le vantail de la porte de manière à n'autoriser le fonctionnement de la came de la cabine que si ladite porte est fermée, caractérisée en ce que le pène de verrouillage (11) est constitué par un cylindre reversible apte à coulisser dans au moins un palier (12) du boîtier (13) qu'il traverse, ledit cylindre (11A) comportant un alésage (11C) débouchant de part en part et dans lequel est disposé un noyau (11B) par rapport auquel est susceptible de coulisser ledit cylindre (11A) lors d'une translation de celui-ci en fermeture normale, le percuteur (8) retenant alors ledit noyau (11B) dans sa position d'origine (A) pour interdire le fonctionnement d'un dispositif de sécurité en cas de fermeture normale, alors qu'en cas de fermeture anormale révélée par la non-présence du percuteur (8) ou par son mauvais positionnement, le noyau (11B) n'étant pas retenu ou partiellement retenu il suit alors le mouvement du cylindre (11A) de pène (11) et provoque le déclenchement du dispositif de sécurité.

Le principe de fonctionnement connu d'un dispositif de sécurité d'une porte palière d'ascenseur auquel se rattache, préférentiellement mais non exclusivement, l'invention est le suivant:The known operating principle of a safety device for an elevator landing door to which the invention preferably, but not exclusively, is connected:

Comme le montre les figures 1, 1A et 2, 2A, lorsqu'une cabine 1 est à l'étage, sa came de commande 2 est sortie et agit contre un galet 3 qui commande en ouverture un pène 4 d'une serrure traditionnelle 5 disposée dans un montant 7 d'une huisserie. Dans cette situation, la porte palière 6 peut s'ouvrir.As shown in Figures 1, 1A and 2, 2A, when a cabin 1 is upstairs, its control cam 2 is extended and acts against a roller 3 which opens a bolt 4 of a traditional lock 5 arranged in an upright 7 of a frame. In this situation, the landing door 6 can open.

Lors d'une commande de la cabine 1 en montée ou en descente, l'ordre ne peut être exécuté que si la porte 6 est fermée et bien fermée.When controlling the cabin 1 up or down, the order can only be executed if the door 6 is closed and closed properly.

En effet, un percuteur fixe 8 solidaire de la porte est disposé en regard du pène (

Figure imgb0001
) de manière à agir sur un dispositif de sécurité mécanique interne au pène, afin de le libérer en verrouillage.Indeed, a fixed striker 8 secured to the door is disposed opposite the bolt (
Figure imgb0001
) so as to act on a mechanical safety device internal to the bolt, in order to release it when locked.

Si la libération du pène n'est pas effectuée ou partiellement effectuée, un contact électrique de pène n'agit pas en fermeture et l'ordre ne peut être exécuté.If the bolt release is not carried out or partially carried out, an electrical bolt contact does not act in closing and the order cannot be executed.

Ce principe de fonctionnement est connu en soi et par conséquent ne sera pas décrit plus avant.This operating principle is known per se and therefore will not be described further.

A titre d'exemple non limitatif, l'invention ci-après décrite, s'applique à un ascenseur dont la cabine est munie d'une porte battante.By way of nonlimiting example, the invention described below applies to an elevator whose cabin is provided with a hinged door.

La serrure universelle 10, désignée dans son ensemble, comprend un pène de verrouillage 11 qui est constitué par un cylindre 11A apte à coulisser dans au moins un palier 12 du boîtier 13 qu'il traverse, ledit cylindre 11A comportant un alésage 11C débouchant de part en pat et dans lequel est disposé un noyau 11B par rapport auquel est susceptible de coulisser ledit cylindre 11A lors d'une translation de celui-ci en fermeture normale. Le percuteur 8 retenant alors ledit noyau 11B dans sa position d'origine A pour interdire le fonctionnement d'un dispositif de sécurité en cas de fermeture normale, alors qu'en cas de fermeture anormale révélée par la non-présence du percuteur 8 (porte ouverte) ou par son mauvais positionnement (porte mal fermée ou défaut de positionnement de la serrure), le noyau 11B n'étant pas retenu ou partiellement retenu il suit alors le mouvement du cylindre 11A de pène 11 et provoque le déclenchement du dispositif de sécurité.The universal lock 10, designated as a whole, comprises a locking bolt 11 which is constituted by a cylinder 11A capable of sliding in at least one bearing 12 of the housing 13 which it passes through, said cylinder 11A comprising a bore 11C opening out through in pat and in which is disposed a core 11B with respect to which said cylinder 11A is capable of sliding during a translation of the latter in normal closure. The striker 8 then retaining said core 11B in its original position A to prohibit the operation of a safety device in the event of normal closing, while in the event of abnormal closing revealed by the non-presence of the striker 8 (door open) or by its bad positioning (door closed improperly or faulty positioning of the lock), the core 11B not being retained or partially retained it then follows the movement of the cylinder 11A of bolt 11 and causes the triggering of the safety device .

Sur la figure 3 les repères D et G signifient un positionnement de l'élément correspondant, à droite ou à gauche.In FIG. 3, the marks D and G signify a positioning of the corresponding element, on the right or on the left.

Le dispositif de sécurité est constitué par un cliquet 14 articulé autour d'un axe fixe 15 du boîtier 13 et comportant à sa partie opposée un talon 16 en appui sur une tête extérieure 17 du noyau 11B de pène 11 sur laquelle il agit en compression par l'intermédiaire d'un ressort de poussée 18. Le cliquet 14 comporte un ergot de verrouillage 19, disposé entre le talon 16 et l'axe 15, et qui est apte à coopérer avec au moins une dent correspondante 20 du cylindre 11A de pène 11 pour le retenir en cas de libération du noyau 11B provoquant conséquemment celle du cliquet 14 et l'immobilisation du pène 11 au cours de sa course en fermeture.The safety device is constituted by a pawl 14 articulated around a fixed axis 15 of the housing 13 and comprising at its opposite part a heel 16 bearing on an external head 17 of the core 11B of bolt 11 on which it acts in compression by by means of a thrust spring 18. The pawl 14 has a locking pin 19, disposed between the heel 16 and the axis 15, and which is able to cooperate with at least one corresponding tooth 20 of the cylinder 11A of bolt 11 to retain it in the event of release of the core 11B consequently causing that of the pawl 14 and the immobilization of the bolt 11 during its closing stroke.

En fait, la dent de retenue 20 du cylindre 11A est délimitée par une gorge concentrique 21, ménagée sur la périphérie de celui-ci, de manière à autoriser toutes positions angulaires autour de son axe longitudinal XX'.In fact, the retaining tooth 20 of the cylinder 11A is delimited by a concentric groove 21, formed on the periphery thereof, so as to allow all angular positions around its longitudinal axis XX '.

Une pluralité de gorges concentriques 21 sont réalisées sur le cylindre 11A à une distance l'une de l'autre correspondant à des étapes de fermeture du pène 11 selon les normes de sécurité imposées.A plurality of concentric grooves 21 are formed on the cylinder 11A at a distance from one another corresponding to steps for closing the bolt 11 according to the safety standards imposed.

Par ailleurs, le cylindre 11A de pène 11 comporte des moyens de guidage 22 réalisés sur au moins une de ses génératrices et coopèrent avec un doigt de guidage fixe 23 assurant simultanément le guidage en translation du pène 11 et sa retenue en rotation autour de son axe XX'.Furthermore, the bolt cylinder 11A 11 comprises guide means 22 produced on at least one of its generatrices and cooperate with a fixed guide finger 23 simultaneously ensuring the translational guiding of the bolt 11 and its retention in rotation about its axis XX '.

En fait, les moyens de guidage du cylindre 11A de pène 11 comportent quatre rainures de guidage 22 formant entre elles un angle de 90° de manière à conférer audit pène 11 la possibilité d'être orienté autour de son axe XX' selon quatre possibilités, en fonction de la position souhaitée de son biseau d'attaque d'extrémité 24.In fact, the means for guiding the cylinder 11A of bolt 11 comprise four guide grooves 22 forming between them an angle of 90 ° so as to give said bolt 11 the possibility of being oriented around its axis XX ′ according to four possibilities, depending on the desired position of its end leading bevel 24.

Selon une variante de réalisation non représentée les moyens de guidage du cylindre 11A du pène 11 sont constitués par un méplat réalisé sur une génératrice du pène 11 apte à coopérer avec un méplat correspondant d'un palier amovible 12 du boîtier, ledit palier présentant quatre côtés externes perpendiculaires le rendant amovible selon quatre positions différentes, de manière à conférer audit pène 11 la possibilité d'être orienté autour de son axe XX' selon quatre possibilités, en fonction de la position souhaitée du biseau d'attaque d'extrémité 24 dudit pène.According to a variant embodiment not shown, the means for guiding the cylinder 11A of the bolt 11 consist of a flat formed on a generatrix of the bolt 11 capable of cooperating with a corresponding flat of a removable bearing 12 of the housing, said bearing having four sides external perpendiculars making it removable in four different positions, so as to give said bolt 11 the possibility of being oriented around its axis XX 'in four possibilities, as a function of the desired position of the end bevel attack 24 of said bolt .

Le noyau 11B de pène 11 comporte un logement borgne axial 26 réalisé à l'extrémité opposée de celle coopérant avec le percuteur 8 et dans lequel est disposé un ressort 27 monté en compression entre le fond 26a dudit logement 26 et le fond 28a d'un autre logement borgne 28 réalisé dans un bouchon de fermeture 29 opposé au palier 12 dans lequel coulisse le pène 11.The core 11B of bolt 11 comprises an axial blind housing 26 produced at the opposite end from that cooperating with the striker 8 and in which is disposed a spring 27 mounted in compression between the bottom 26a of said housing 26 and the bottom 28a of a another blind housing 28 produced in a closure cap 29 opposite the bearing 12 in which the bolt 11 slides.

Le bouchon de fermeture 29 et le palier 12 du pène 11 sont réversibles et se substituent l'un à l'autre, selon que le pène 11 se trouve d'un côté Droit ou de l'autre Gauche du boîtier 13.The closure plug 29 and the bearing 12 of the bolt 11 are reversible and replace one another, depending on whether the bolt 11 is on a Right or the Left side of the housing 13.

Du fond 28a du logement borgne 28 du bouchon 29 est issu un axe de guidage 30 du ressort 27 et du noyau 11B de pène 11.From the bottom 28a of the blind housing 28 of the plug 29 comes a guide pin 30 of the spring 27 and of the core 11B of bolt 11.

Selon une autre caractéristique de l'invention, l'extrémité du cylindre 11A de pène 11 dirigée vers la tête externe de son noyau 11B comporte des moyens de fixation amovibles 32 d'un support diélectrique mobile 31 sur lequel sont disposés symétriquement deux organes de liaison électrique 33 et 34.According to another characteristic of the invention, the end of the cylinder 11A of bolt 11 directed towards the external head of its core 11B comprises removable fixing means 32 of a movable dielectric support 31 on which two connecting members are arranged symmetrically electric 33 and 34.

Ces moyens 32 sont constitués par une vis traversant une partie du support mobile 31 et se vissant dans l'un des quatre trous filetés 35 réalisés radialement dans le cylindre 11A de pène 11 selon un écart angulaire de 90°.These means 32 consist of a screw passing through part of the movable support 31 and screwing into one of the four threaded holes 35 made radially in the bolt cylinder 11A at an angular distance of 90 °.

Selon une variante de réalisation le support diélectrique mobile 31 comporte à sa partie inférieure au moins une rainure transversale apte à permettre son coulissement sur un rail correspondant ménagé sur le fond du boitier, par entraînement direct du levier de commande 49 se logeant librement dans une encoche en forme de U dudit support diélectrique mobile 31.According to an alternative embodiment, the mobile dielectric support 31 has at its lower part at least one transverse groove capable of allowing it to slide on a corresponding rail formed on the bottom of the housing, by direct drive of the control lever 49 being freely housed in a notch. U-shaped of said movable dielectric support 31.

Les organes de liaison électriques 33, 34 sont susceptibles de court-circuiter d'une part, le contact électrique de présence 36 dans une position déverrouilllée A du pène 11 et d'autre part, le contact électrique 37 de pène 11 dans une position de verrouillage complet B du même pène 11.The electrical connecting members 33, 34 are capable of short-circuiting on the one hand, the electrical presence contact 36 in an unlocked position A of the bolt 11 and on the other hand, the electrical contact 37 of bolt 11 in a position complete locking B of the same bolt 11.

Selon une caractéristique de l'invention, le contact de présence 36 et le contact 37 de pène 11 sont disposés symétriquement de part et d'autre du boîtier 13.According to a characteristic of the invention, the presence contact 36 and the pin contact 37 11 are arranged symmetrically on either side of the housing 13.

La serrure dispose également d'un contact à arrachement 38 de la porte battante 6 qui peut être fixé sur une paroi latérale du boîtier 13, à la demande.The lock also has a tear-off contact 38 of the hinged door 6 which can be fixed to a side wall of the housing 13, on request.

Selon une caractéristique de l'invention, le contact de présence 36, le contact 37 de pène 11 et le contact à arrachement 38 sont identiques et comporte des moyens de fixation dépendant de leur sens de montage.According to a characteristic of the invention, the presence contact 36, the bolt contact 37 and the tear-off contact 38 are identical and includes fixing means depending on their direction of mounting.

En fait, concernant le contact de présence 36 et le contact 37 de pène 11, leur fixation s'effectue directement dans un logement 39 ou 40 du boîtier 13 par un système de glissières en queue d'aronde 41 dans un sens vertical, alors que s'agissant du contact à arrachement 38, celui-ci, identique aux précédents, est monté dans un sens horizontal.In fact, concerning the presence contact 36 and the contact 37 of bolt 11, their fixing is carried out directly in a housing 39 or 40 of the housing 13 by a system of dovetail slides 41 in a vertical direction, while as regards the pull-out contact 38, this, identical to the previous ones, is mounted in a horizontal direction.

Bien entendu, les queues d'aronde peuvent être remplacées par tout autre moyen.Of course, the dovetails can be replaced by any other means.

Egalement, des ouvertures 44, 45 destinées à l'insertion du contact à arrachement 38 sont prévues de part et d'autre du boîtier 13 de manière à disposer éventuellement ledit contact sur le boîtier, en fonction de l'ouverture à droite ou à gauche de la porte palière 6, la (ou les) ouverture(s) inoccupée(s) étant bouchée(s) par un cache amovible 46.Also, openings 44, 45 intended for the insertion of the pull-out contact 38 are provided on either side of the housing 13 so as to optionally dispose said contact on the housing, depending on the opening on the right or on the left. of the landing door 6, the unoccupied opening (s) being blocked by a removable cover 46.

Selon une autre caractéristique de l'invention, le contact de présence 36 et le contact 37 de pène 11 sont maintenus en place par l'intermédiaire d'épingles en queue d'aronde 47 comportant des moyens de fixation 48.According to another characteristic of the invention, the presence contact 36 and the bolt contact 37 11 are held in place by means of dovetail pins 47 comprising fixing means 48.

Le levier de commande 49 du pène 11 comporte à l'une de ses extrémités un secteur denté 50 venant en liaison avec les gorges concentriques 21 qui assurent non seulement la retenue éventuelle du pène 11 par le cliquet 14 du dispositif de sécurité, mais également l'ancrage dudit secteur denté 50 du levier de commande 49, à la manière d'une crémaillère. Ceci afin d'assurer le déplacement transversal linéaire du pène 11 en fonction d'un débattement angulaire dudit levier 49 autour d'un axe de rotation 52 du boîtier 13 et à l'encontre d'un ressort de rappel 53 interposé entre une partie fixe d'accrochage 54 sur le boîtier 13 et une partie arrière 55 du levier de commande 49.The control lever 49 of the bolt 11 has at one of its ends a toothed sector 50 coming in connection with the concentric grooves 21 which ensure not only the possible retention of the bolt 11 by the pawl 14 of the safety device, but also the anchoring of said toothed sector 50 of the control lever 49, in the manner of a rack. This is to ensure the linear transverse displacement of the bolt 11 as a function of an angular movement of said lever 49 around an axis of rotation 52 of the housing 13 and against a return spring 53 interposed between a fixed latching part 54 on the housing 13 and a rear part 55 of the control lever 49.

Selon une variante de réalisation le ressort de rappel est disposé concentriquement au noyau 11B entre la tête 17 dudit noyau et un épaulement interne (non représenté) réalisé dans l'alésage 11C du pène 11.According to an alternative embodiment, the return spring is arranged concentrically with the core 11B between the head 17 of said core and an internal shoulder (not shown) produced in the bore 11C of the bolt 11.

Selon l'esprit général de l'invention, le levier de commande 49 est réversible de manière à pouvoir assurer sa fonction quelle que soit le sens de fonctionnement du pène 11 par rapport au boîtier 13.According to the general spirit of the invention, the control lever 49 is reversible so as to be able to perform its function regardless of the direction of operation of the bolt 11 relative to the housing 13.

Selon une autre caractéristique de l'invention, le levier de commande 49 du pène 11 est en liaison avec le bras de manoeuvre externe 56 par l'intermédiaire d'un axe 57 comportant deux têtes d'entraînement 58 constituées par des prismes mâles à section triangulaire, dont l'un 58a coopère avec un logement correspondant d'un élément du bras 56 et l'autre 56b reste libre et est accessible depuis l'extension du boîtier et de l'huisserie de manière à permettre un éventuel déverrouillage manuel du pène 11.According to another characteristic of the invention, the control lever 49 of the bolt 11 is in connection with the external operating arm 56 by means of an axis 57 comprising two drive heads 58 constituted by male prisms with section triangular, one of which 58 a cooperates with a corresponding housing of an element of the arm 56 and the other 56 b remains free and is accessible from the extension of the housing and of the frame so as to allow possible manual unlocking of the bolt 11.

Comme le montre la figure 8, la manoeuvre manuelle peut être effectuée par l'intermédiaire d'une autre tête triangulaire 58c solidaire d'un pignon 60 en prise directe avec un pignon 59 ménagé sur un moyeu du bras 49. Ainsi, la serrure pourra être débloquée manuellement par intervention sur les triangles 58a ou 58c selon deux positions de la serrure 10 dans le montant de l'huisserie à travers deux trous ménagés dans celui-ci.As shown in FIG. 8, the manual maneuver can be carried out by means of another triangular head 58c secured to a pinion 60 in direct engagement with a pinion 59 formed on a hub of the arm 49. Thus, the lock can be unlocked manually by intervention on the triangles 58 a or 58 c in two positions of the lock 10 in the amount of the frame through two holes formed therein.

Cette double position de la serrure 10 est également rendu possible par le fait que le fond du boîtier 13 comporte deux ouvertures 62, 63 destinées au passage au choix de l'axe 52 du bras d'entraînement 56 vers le levier de commande 49, de manière à autoriser deux positions du boîtier 13 choisies en fonction de la largeur du montant de l'huisserie, sans modification de la longueur du pène 11.This double position of the lock 10 is also made possible by the fact that the bottom of the housing 13 has two openings 62, 63 intended for the passage, as desired, of the axis 52 of the drive arm 56 towards the control lever 49, so as to allow two positions of the housing 13 chosen as a function of the width of the upright of the frame, without modifying the length of the bolt 11.

Selon une autre caractéristique de l'invention représentée sur la figure 11, le jeu de pièces détachées fournies et disposées en attente dans un logement 64 du boîtier 13 sont constitués d'une part par une pièce de renvoi 65 disposée si besoin verticalement, dans un logement 67 du boîtier 13 pour être traversée perpendiculairement par un élément rotatif 52 du bras de manoeuvre 56, et d'autre part un axe 66 traversant radialement ledit bras 56 et dont l'extrémité forme une rotule 68 apte à coopérer pour entraînement avec une encoche 69 réalisée dans le levier de commande 49.According to another characteristic of the invention shown in FIG. 11, the set of spare parts supplied and arranged in standby in a housing 64 of the housing 13 are constituted on the one hand by a return piece 65 arranged if necessary vertically, in a housing 67 of the housing 13 to be crossed perpendicularly by a rotary element 52 of the operating arm 56, and on the other hand an axis 66 passing radially through said arm 56 and the end of which forms a ball joint 68 able to cooperate for driving with a notch 69 produced in the control lever 49.

Le logement 64 comporte également un emplacement destiné à mettre en réserve une pluralité de caches 46 dont l'utilisation se fera selon les cas de figures rencontrés. Le mode de réalisation représenté sur les figures 12 et 13 diffère exclusivement de celui de la figure 11 qui vient d'être évoqué, par le fait que le bras 56 muni de son axe 66 à rotule 68 n'est pas perpendiculaire au plan du levier 49 mais se trouve dans son prolongement pour couvrir un cas de figure différent.The housing 64 also includes a location intended to reserve a plurality of covers 46, the use of which will be made according to the cases encountered. The embodiment shown in Figures 12 and 13 differs exclusively from that of Figure 11 which has just been mentioned, in that the arm 56 provided with its axis 66 with ball 68 is not perpendicular to the plane of the lever 49 but is in its extension to cover a different case.

Dans tous les cas la pièce de renvoi 65 est maintenue dans l'encoche 67 du boîtier 13, par l'intermédiaire de vis de fixation 70. Bien entendu, une encoche 69 est prévue de part et d'autre du boîtier pour pouvoir inverser le bras 56, à droite ou à gauche. Dans ce cas, l'encoche libre sera également bouchée par un cache 46.In all cases the return piece 65 is held in the notch 67 of the housing 13, by means of fixing screws 70. Of course, a notch 69 is provided on either side of the housing in order to be able to reverse the arm 56, right or left. In this case, the free notch will also be blocked by a cover 46.

Selon une autre caractéristique de l'invention, le dispositif de passe-câbles 71 est constitué par deux logements transversaux 72, 73 réalisés en regard l'un de l'autre, à la fois dans le boîtier 13 et dans le couvercle 75 et dans lesquels les logements sont disposés des blocs de mousse 76, 77 aptes à pincer élastiquement sans les blesser, les conducteurs électriques issus des contacts 36, 37, 38.According to another characteristic of the invention, the cable passage device 71 consists of two transverse housings 72, 73 made opposite one another, both in the housing 13 and in the cover 75 and in which the housings are arranged in blocks of foam 76, 77 able to pinch elastically without injuring them, the electrical conductors coming from the contacts 36, 37, 38.

Selon une autre caractéristique de l'invention, la fixation du boîtier 13 est assurée selon deux positions, relativement à la largeur du montant de l'huisserie 7, grâce à deux plaquettes rigides 78, 79 rapportée dans des logements correspondants 80, 81 réalisés aux extrémités du boîtier 13, le fond de ces logements comportant une lumière oblongue 82, 83 alors que les plaquettes 78, 80 sont munies d'une pluralité de trous 84 à 87 et 88 à 91 destinés au passage de vis de fixation du boîtier et choisis en fonction de la position à donner audit boîtier 13 par rapport au montant de l'huisserie 7.According to another characteristic of the invention, the housing 13 is fixed in two positions, relative to the width of the upright of the frame 7, by virtue of two rigid plates 78, 79 added in corresponding housings 80, 81 produced at the ends of the housing 13, the bottom of these housings comprising an oblong opening 82, 83 while the plates 78, 80 are provided with a plurality of holes 84 to 87 and 88 to 91 intended for the passage of screws for fixing the housing and chosen as a function of the position to be given to said housing 13 relative to the upright of the frame 7.

Les trous précités, au nombre de quatre par plaquette 78 ou 79, sont assymétriques deux à deux par rapport à l'axe transversal de la plaquette considérée, de manière à obtenir des positions différentes par son simple retournement autour de cet axe.The aforementioned holes, four in number per plate 78 or 79, are asymmetrical two by two relative to the transverse axis of the plate considered, so as to obtain different positions by its simple turning around this axis.

Selon une autre caractéristique de l'invention représentée sur la figure 14, la fixation du bras de manoeuvre 56 par rapport au levier de commande 49 s'effectue par l'intermédiaire de moyen de réglage angulaire de l'un par rapport à l'autre.According to another characteristic of the invention shown in Figure 14, the fixing of the operating arm 56 relative to the control lever 49 is effected by means of angular adjustment means with respect to one another .

Ces moyens sont constitués par une bague concentrique amovible intermédiaire 92 disposée entre un alésage 93 du bras 56 et l'axe porteur 52 du triangle solidaire du levier de commande 49, la liaison de ladite bague 92 avec l'axe 52 s'effectuant par l'intermédiaire d'un dodécagone d'entraînement 92a, alors que la liaison de la même bague avec le bras 56 s'effectue également par un second dodécagone 92b d'entraînement, les deux dodécagones 92a, 92b étant concentriques mais décalés de 5° l'un par rapport à l'autre pour l'obtention d'un réglage angulaire fin, du bras 56.These means consist of an intermediate removable concentric ring 92 disposed between a bore 93 of the arm 56 and the support axis 52 of the triangle secured to the control lever 49, the connection of said ring 92 with the axis 52 being effected by the intermediary of a drive dodecagon 92 a , while the connection of the same ring with the arm 56 is also effected by a second drive dodecagon 92 b , the two dodecagons 92 a , 92 b being concentric but offset 5 ° relative to each other to obtain a fine angular adjustment of the arm 56.

Selon une autre caractéristique de l'invention (non représentée) des moyens de débrayage sont interposés entre le levier de commande 49 et l'axe porteur 52 du triangle 58 solidaire dudit levier 49.According to another characteristic of the invention (not shown) declutching means are interposed between the control lever 49 and the carrier axis 52 of the triangle 58 secured to said lever 49.
