Description

L'invention est relative à une serrure, en particulier à plusieurs points, destinée à être posée en applique contre une porte, et comprenant une sûreté intérieure et une sûreté extérieure, chacune de ces sûretés comportant un stator et un rotor propre à être commandé par une clé pour agir sur un mécanisme d'entraînement destiné à actionner au moins un pêne.The invention relates to a lock, in particular at several points, intended to be applied as a wall against a door, and comprising an interior safety and an exterior safety, each of these sureties comprising a stator and a rotor suitable for being controlled by a key for acting on a drive mechanism intended to actuate at least one bolt.

On sait que de telles serrures, qui permet­tent, notamment, d'actionner simultanément plusieurs pênes, constituent des serrures de sécurité permettant d'offrir une résistance importante aux tentatives d'effraction. Toutefois, pour assurer une sécurité maximale aux personnes qui sont seules habilitées à se servir du local protégé par la serrure, il convient de réduire au minimum le risque d'une reproduction non autorisée de la clé permettant l'ouverture d'une telle serrure.It is known that such locks, which make it possible, in particular, to actuate several bolts simultaneously, constitute security locks making it possible to offer significant resistance to attempted break-ins. However, to ensure maximum security for persons who are the only ones authorized to use the room protected by the lock, the risk of unauthorized reproduction of the key allowing the opening of such a lock should be minimized.

Actuellement, les clés destinées à de telles serrures sont placées sous emballage scellé de telle sorte que l'occupant autorisé sera certain que per­sonne d'autre que lui n'a eu accès à ces clés lorsqu'il ouvrira l'emballage scellé. Une telle façon d'opérer est cependant relativement gênante pour les raisons expliquées ci-après.Currently, the keys intended for such locks are placed in sealed packaging so that the authorized occupant will be certain that no one other than him has had access to these keys when he opens the sealed packaging. However, such a way of operating is relatively inconvenient for the reasons explained below.

La pose d'une serrure de ce type, nécessitant divers réglages, notamment lorsque plusieurs pênes sont commandés, est relativement délicate de sorte qu'il existe une contrainte car, ou bien la serrure n'est posée qu'à la remise des clés, ou bien la serrure est posée mais reste en position ouverte et tout le monde peut avoir accès au local aussi longtemps que l'occupant autorisé n'en a pas pris possession.The installation of a lock of this type, requiring various adjustments, in particular when several bolts are ordered, is relatively delicate so that there is a constraint because either the lock is only placed when the keys are handed over, or the lock is placed but remains in the open position and everyone can have access to the room as long as the authorized occupant has not taken possession of it.

Un tel cas de figure se produit, par exem­ple, lors de la construction de logements neufs ; les serrures des portes des appartements sont généralement posées avant que les occupants prennent possession de leur logement, et avant que ces logements ne soient complètement terminés. Il est donc nécessaire de con­tinuer à permettre l'accès aux logements à divers corps de métier, dont le personnel devra ainsi détenir une clé de la serrure, ce qui n'est pas satisfaisant du point de vue de la sécurité.Such a scenario occurs, for example, during the construction of new housing; apartment door locks are generally installed before the occupants take possession of their accommodation, and before the accommodation is completely finished. It is therefore necessary to continue to allow access to housing for various trades, whose personnel will thus have to hold a key to the lock, which is not satisfactory from the point of view of security.

Il est possible, en fin de chantier, de démonter les sûretés intérieure et extérieure de la serrure pour les remplacer, au dernier moment, par des sûretés dont seul l'occupant de l'appartement aura la clé, mais ces opérations de démontage et de remontage sont relativement délicates dans les serrures actuelles.It is possible, at the end of the work, to dismantle the interior and exterior security of the lock and replace them, at the last moment, with security of which only the occupant of the apartment will have the key, but these dismantling and reassembly are relatively delicate in current locks.

Un problème analogue se pose lorsque l'occupant autorisé d'un local a perdu une clé et veut faire changer les sûretés intérieure et extérieure pour faire commander l'ouverture et la fermeture par une autre clé.A similar problem arises when the authorized occupant of a room has lost a key and wants to change the interior and exterior security to order the opening and closing by another key.

L'invention a pour but, surtout, de fournir une serrure du genre défini précédemment qui permette de mieux résoudre que jusqu'à présent le problème évoqué ci-dessus.The object of the invention is, above all, to provide a lock of the kind defined above which enables the problem mentioned above to be better resolved than hitherto.

L'invention a également pour but de fournir une serrure du genre défini précédemment qui soit d'une conception simple et robuste tout en restant relativement économique.The invention also aims to provide a lock of the kind defined above which is of a simple and robust design while remaining relatively economical.

Selon l'invention, une serrure, en particu­lier à plusieurs points, destinée à être posée en applique contre une porte, et comprenant une sûreté intérieure et une sûreté extérieure, chacune de ces sûretés comportant un stator et un rotor propre à être commandé par une clé pour agir sur un mécanisme d'entraînement destiné à actionner au moins un pêne, est caractérisée par le fait qu'elle comprend un bloc constitué d'une sorte de boîtier contenant le mécanisme d'entraînement, et présentant deux parois opposées sur lesquelles sont fixés, respectivement, les stators de la sûreté intérieure et de la sûreté extérieure, le boîtier comportant des moyens de fixa­tion du bloc sur la porte, ces moyens étant situés à l'extérieur du contour des susdits stators, tandis que le mécanisme d'entraînement comprend au moins un organe d'entraînement dont une partie fait saillie hors du boîtier pour coopérer avec un système de com­mande d'au moins un pêne, monté sur la porte, par un simple mouvement de translation suivant une direction sensiblement orthogonale au plan moyen de la porte, de telle sorte que l'ensemble du bloc, formé du boîtier et des sûretés soit aisément interchangeable.According to the invention, a lock, in particular at several points, intended to be applied as a wall against a door, and comprising an interior safety and an exterior safety, each of these sureties comprising a stator and a rotor suitable for being controlled by a key to act on a mechanism drive intended to actuate at least one bolt, is characterized by the fact that it comprises a block made up of a kind of housing containing the drive mechanism, and having two opposite walls on which the stators are fixed, respectively internal security and external security, the housing comprising means for fixing the block to the door, these means being located outside the contour of the above stators, while the drive mechanism comprises at least one member drive, part of which protrudes from the housing to cooperate with a control system of at least one bolt, mounted on the door, by a simple translational movement in a direction substantially orthogonal to the mean plane of the door, so that that the entire block, made up of the housing and the collateral, is easily interchangeable.

Ainsi, selon l'invention, par un démontage extrêmement simple du bloc, il est possible de changer aisément les sûretés intérieure et extérieure, et donc les clés qui commandent la serrure, sans avoir à démonter d'autres pièces, notamment au niveau du système de commande des pênes, qui nécessite un réglage relativement délicat.Thus, according to the invention, by an extremely simple disassembly of the block, it is possible to easily change the internal and external security, and therefore the keys which control the lock, without having to dismantle other parts, in particular at the system level. bolt control, which requires a relatively delicate adjustment.

En particulier, dans le cas de la construc­tion de logements neufs, il sera possible de monter l'ensemble des pièces de la serrure sur la porte, et d'équiper cette serrure d'un bloc provisoire dont les clés seront données au personnel des divers corps de métier devant intervenir dans l'appartement non ter­miné ; à la livraison de l'appartement, le bloc pro­visoire sera remplacé par le bloc définitif en présence de l'occupant autorisé de l'appartement auquel seront remises les clés définitives sous embal­lage scellé. Cet occupant sera donc le seul à avoir eu en mains les clés de sa serrure.In particular, in the case of new housing construction, it will be possible to mount all of the parts of the lock on the door, and to equip this lock with a temporary block, the keys of which will be given to the personnel of the various trades to intervene in the unfinished apartment; on delivery of the apartment, the temporary block will be replaced by the final block in the presence of the authorized occupant of the apartment to whom the final keys will be given in sealed packaging. This occupant will therefore be the only one to have had the keys to his lock in hand.

De préférence, les stators fixés sur le boîtier sont des cylindres à section transversale cir­culaire, dont les axes sont alignés.Preferably, the stators fixed to the housing are cylinders of circular cross section, the axes of which are aligned.

L'organe d'entraînement est avantageusement constitué par une roue dentée à denture droite, dont l'axe de rotation est orthogonal aux susdites parois du boîtier et dont une partie de la denture fait sail­lie hors du boîtier de manière à pouvoir être engagée dans la denture d'une roue conjuguée du système de commande des pênes.The drive member is advantageously constituted by a toothed wheel with straight teeth, the axis of rotation of which is orthogonal to the aforesaid walls of the housing and of which a portion of the teeth protrudes from the housing so that it can be engaged in the toothing of a conjugate wheel of the bolt control system.

Le boîtier peut comprendre un support qui comporte un palier pour la susdite roue dentée et un logement pour un mécanisme d'entraînement de cette roue, ce logement étant fermé par une plaque rapportée (foncet).The housing may include a support which comprises a bearing for the above-mentioned toothed wheel and a housing for a drive mechanism for this wheel, this housing being closed by an attached plate (plow).

Les moyens de fixation du boîtier sont formés de préférence par des trous, notamment de forme oblongue, traversant le boîtier suivant une direction parallèle à l'axe des stators.The fixing means of the housing are preferably formed by holes, in particular of oblong shape, passing through the housing in a direction parallel to the axis of the stators.

Avantageusement, un jeu d'engrenages est prévu dans le mécanisme d'entraînement de manière à démultiplier, au niveau de la roue dentée, le mouve­ment de rotation de chaque rotor sous l'action d'une clé.Advantageously, a set of gears is provided in the drive mechanism so as to multiply, at the level of the toothed wheel, the rotational movement of each rotor under the action of a key.

De préférence, les rotors de la sûreté intérieure et de la sûreté extérieure commandent un seul et même organe entraîneur situé dans le boîtier et monté rotatif coaxialement aux rotors.Preferably, the internal safety and external safety rotors control a single driving member located in the housing and mounted to rotate coaxially with the rotors.

Cet organe entraîneur est constitué par une sorte de manchon disposé coaxialement aux rotors, à l'intérieur du logement du support, et comportant sen­siblement à mi-longueur une paroi séparant l'intérieur du manchon en deux compartiments, une pièce extérieure et intérieure, liée au rotor respectif, étant montée tournante dans chaque compartiment de l'organe entraîneur, des moyens de couplage étant prévus du côté intérieur et du côté extérieur pour établir une liaison en rotation entre l'organe entraîneur et celle des pièces tournantes correspondant au rotor dans lequel la clé est engagée.This driving member is constituted by a sort of sleeve arranged coaxially with the rotors, inside the support housing, and comprising substantially at mid-length a wall separating the interior of the sleeve into two compartments, an external and internal part, linked to the respective rotor, being rotatably mounted in each compartment of the driving member, coupling means being provided for internal side and external side to establish a connection in rotation between the driving member and that of the rotating parts corresponding to the rotor in which the key is engaged.

Avantageusement, les moyens de couplage sont agencés pour permettre d'actionner la serrure de l'extérieur alors qu'elle n'est pas en position de repos du fait que la clé n'est pas retirée de la ser­rure du côté intérieur.Advantageously, the coupling means are arranged to allow the lock to be actuated from the outside while it is not in the rest position because the key is not withdrawn from the lock from the inside.

Les moyens de couplage comprennent, du côté de la sûreté intérieure, un mobile intérieur monté coulissant dans la pièce tournante intérieure compor­tant un prolongement en saillie dans le logement du rotor contre lequel la clé est propre à venir en appui en fin d'introduction, tandis que la paroi intermédiaire de l'organe entraîneur comporte un pas­sage, dont la section transversale est identique à celle du mobile intérieur, de telle sorte que ledit mobile puisse être poussé dans ce passage, pour assurer une liaison en rotation entre le rotor intérieur et l'organe entraîneur, lorsque la position angulaire relative du rotor intérieur et de l'organe entraîneur est correcte.The coupling means comprise, on the internal safety side, an internal mobile mounted to slide in the internal rotating part comprising a protruding extension in the housing of the rotor against which the key is capable of coming to bear at the end of introduction, while that the intermediate wall of the driving member has a passage, the cross section of which is identical to that of the inner mobile, so that said mobile can be pushed into this passage, to ensure a connection in rotation between the inner rotor and the 'drive member, when the relative angular position of the inner rotor and the drive member is correct.

Un organe de condamnation est prévu du côté de la pièce tournante extérieure, cet organe de con­damnation ayant même section transversale que le mobile intérieur et étant situé à la même distance radiale de l'axe commun du rotor intérieur et du rotor extérieur, ledit organe de condamnation étant solli­cité élastiquement, en particulier par un ressort, pour entrer dans le susdit passage lorsque la position angulaire relative de la pièce tournante extérieure et de l'organe entraîneur le permet ; dans cette posi­tion, où l'organe de condamnation est aligné avec le mobile intérieur, ce dernier repousse l'organe de con­damnation lorsque la clé est engagée dans le rotor intérieur, et libère en rotation l'organe entraîneur par rapport à la pièce tournante extérieure.A locking member is provided on the side of the outer rotating part, this locking member having the same cross section as the inner mobile and being located at the same radial distance from the common axis of the inner rotor and the outer rotor, said locking member condemnation being elastically urged, in particular by a spring, to enter the aforementioned passage when the relative angular position of the external rotating part and of the driving member allows it; in this position, where the locking member is aligned with the internal mobile, the latter pushes the locking member when the key is engaged in the rotor inside, and frees the driving member in rotation relative to the external rotating part.

La pièce tournante extérieure comporte, en outre, un organe d'embrayage, mobile suivant une direction parallèle à l'axe des rotors, maintenu écarté élastiquement de la paroi intermédiaire de l'organe entraîneur, et propre à être appliqué élas­tiquement contre cette paroi lorsqu'une clé est engagée dans le rotor extérieur et, en fin d'introduction, pousse un organe détecteur de clé qui retenait écarté le susdit organe d'embrayage ; un pas­sage de section identique à celle dudit organe d'embrayage est prévu dans la paroi intermédiaire de l'organe entraîneur, de telle sorte que cet organe d'embrayage puisse entrer dans ledit passage lorsqu'il est poussé à la suite de l'introduction d'une clé dans le rotor extérieur.The external rotating part further comprises a clutch member, movable in a direction parallel to the axis of the rotors, kept elastically spaced from the intermediate wall of the driving member, and suitable for being applied elastically against this wall when 'A key is engaged in the outer rotor and, at the end of introduction, pushes a key detecting member which held aside the above-mentioned clutch member; a passage of identical section to that of said clutch member is provided in the intermediate wall of the driving member, so that this clutch member can enter said passage when it is pushed after the introduction a key in the outer rotor.

Avantageusement, la section transversale de l'organe d'embrayage est différente de celle de l'organe de condamnation, les formes et dimensions étant choisies de manière telle que l'organe d'embrayage ne puisse entrer dans le passage de la paroi intermédiaire correspondant à l'organe de con­damnation et qu'inversement, ledit organe de condamna­tion ne puisse entrer dans le passage réservé à l'organe d'embrayage ; en particulier, la section transversale de l'organe d'embrayage est rectangu­laire, tandis que celle de l'organe de condamnation est circulaire.Advantageously, the cross section of the clutch member is different from that of the locking member, the shapes and dimensions being chosen so that the clutch member cannot enter the passage of the corresponding intermediate wall. to the locking member and that, conversely, said locking member cannot enter the passage reserved for the clutch member; in particular, the cross section of the clutch member is rectangular, while that of the locking member is circular.

Le détecteur de clé, prévu dans le rotor extérieur, est formé par une sorte de barrette présentant sur sa face tournée radialement vers l'intérieur du rotor, une échancrure longitudinale limitée, à ses deux extrémités, par des rebords ; le rebord le plus proche du boîtier sert de butée à un cran de retenue prévu sur la pièce d'embrayage, laquelle est poussée contre ce cran par un ressort d'embrayage qui prend appui contre l'autre rebord du détecteur de clé.The key detector, provided in the outer rotor, is formed by a sort of bar having on its face turned radially towards the inside of the rotor, a longitudinal notch limited, at its two ends, by flanges; the flange closest to the housing serves as a stop for a retaining notch provided on the clutch part, which is pushed against this notch by a clutch spring which bears against the other edge of the key detector.

Ce détecteur de clé est sollicité par un autre ressort propre à l'écarter de la pièce tournante extérieure ; ce ressort peut prendre appui contre l'organe de condamnation.This key detector is biased by another spring capable of removing it from the external rotating part; this spring can bear against the locking member.

L'invention est également relative à un bloc interchangeable, pour serrure destinée à être posée en applique sur une porte, notamment une serrure à plusieurs points, ce bloc présentant les caractéristiques énoncées précédemment.The invention also relates to an interchangeable block, for a lock intended to be placed on the wall on a door, in particular a multi-point lock, this block having the characteristics set out above.

L'invention consiste, mises à part les dispositions exposées ci-dessus, en un certain nombre d'autres dispositions dont il sera plus explicitement question ci-après à propos d'un mode de réalisation particulier décrit avec référence aux dessins ci-­annexés, mais qui n'est nullement limitatif.

En se reportant aux figures 1 et 2 des des­sins, on peut voir une serrure 1 à plusieurs points sommairement représentée, destinée à être posée en applique contre une porte 2. Une plaque métallique de blindage p peut être fixée sur la face intérieure de la porte 2, comme visible sur la figure 1.Referring to Figures 1 and 2 of the drawings, one can see a lock 1 at several points roughly shown, intended to be applied as a wall against a door 2. A metal plate of shielding p can be fixed on the inside of the door 2, as shown in Figure 1.

La serrure 1 comprend une sûreté intérieure 3 et une sûreté extérieure 4 comportant chacune un stator, respectivement 5 et 6 (voir figure 3) et un rotor 7, 8 propre à être commandé par une clé. De manière connue, non représentée sur les dessins, un système de paillettes radiales ou équivalent, est prévu dans le rotor pour coopérer avec des poussoirs du stator, l'ensemble étant tel que lorsque la clé appropriée à la serrure a été engagée dans le logement du rotor, les paillettes ou équivalents sont repoussés par la clé d'une manière telle que l'entraînement en rotation du rotor par rapport au stator est possible à l'aide de la clé.The lock 1 comprises an internal security 3 and an external security 4 each comprising a stator, respectively 5 and 6 (see FIG. 3) and a rotor 7, 8 suitable for being controlled by a key. In a known manner, not shown in the drawings, a system of radial flakes or equivalent, is provided in the rotor to cooperate with pushers of the stator, the assembly being such that when the key suitable for the lock has been engaged in the housing of the rotor, the flakes or the like are pushed back by the key in such a way that the rotation of the rotor relative to the stator is possible using the key.

La rotation d'un rotor 7 ou 8 permet d'agir sur un système de commande M schématiquement représenté propre à actionner les différents pênes de la serrure. Sur la figure 2, un pêne horizontal 9 et un pêne vertical 10 situés en haut de la porte ont été sommairement représentés.The rotation of a rotor 7 or 8 makes it possible to act on a control system M diagrammatically shown capable of actuating the various bolts of the lock. In Figure 2, a horizontal bolt 9 and a vertical bolt 10 located at the top of the door have been summarily shown.

La serrure 1 comprend un bloc 11 constitué d'une sorte de boîtier 12 contenant un mécanisme d'entraînement 13 et présentant deux parois opposées 14, 15, sur lesquelles sont fixés, respectivement, les stators 5, 6.The lock 1 comprises a block 11 consisting of a kind of housing 12 containing a drive mechanism 13 and having two opposite walls 14, 15, on which the stators 5, 6 are fixed, respectively.

Le contour sensiblement rectangulaire du bloc 11 déborde du contour des stators 5, 6, qu'il entoure complètement.The substantially rectangular outline of the block 11 projects beyond the outline of the stators 5, 6, which it completely surrounds.

Le boîtier 12 comprend un support 16 qui comporte un palier 17 pour une roue dentée 18 à den­ture droite, dont l'axe de rotation est orthogonal aux susdites parois 14, 15. Le support 16 comporte en outre un logement 19 pour le mécanisme d'entraînement 13 de la roue dentée 18 dont il sera question plus loin. Le logement 19 est fermé par une plaque rapportée 20, appelée foncet, dont la face extérieure constitue la susdite paroi 15, tandis que la face du support 16 située du côté opposé au foncet 20 consti­tue la susdite paroi 14.The housing 12 comprises a support 16 which comprises a bearing 17 for a toothed wheel 18 with straight teeth, the axis of rotation of which is orthogonal to the aforesaid walls 14, 15. The support 16 further comprises a housing 19 for the mechanism drive 13 of the toothed wheel 18 which will be discussed later. The housing 19 is closed by an attached plate 20, called a wall, the external face of which constitutes the above-mentioned wall 15, while the face of the support 16 located on the side opposite the wall of the wall 20 constitutes the above-mentioned wall 14.

Le boîtier 12 comporte des moyens de fixa­tion constitués par des trous 21 permettant la fixa­tion du bloc 11 sur la porte 2 à l'aide de vis telles que 22 (figure 1). Les trous 21 ont une forme oblongue et sont avantageusement au nombre de trois ; l'un des trous est coaxial au palier 17, tandis que les deux autres trous sont prévus de part et d'autre de la par­tie inférieure du bloc, leur direction moyenne étant légèrement inclinée de manière à converger du côté opposé au troisième trou. Ces trous 21 sont situés à l'extérieur du contour des stators 5 et 6.The housing 12 comprises fixing means constituted by holes 21 allowing the fixing of the block 11 on the door 2 using screws such as 22 (Figure 1). The holes 21 have an oblong shape and are advantageously three in number; one of the holes is coaxial with the bearing 17, while the other two holes are provided on either side of the lower part of the block, their mean direction being slightly inclined so as to converge on the side opposite to the third hole. These holes 21 are located outside the contour of the stators 5 and 6.

Une partie 23 de la denture de la roue 18 fait saillie hors du boîtier 11 de manière à pouvoir être engagée dans la denture d'une roue conjuguée 24 (figure 2) faisant partie du système de commande des pênes tels que 9 et 10. Le mécanisme de transmission et de transformation du mouvement de rotation de la roue 24 en un mouvement de translation approprié des pênes 9 et 10 n'est pas représenté sur les dessins. L'ensemble de ces mécanismes est recouvert par un carter 25 fixé contre la porte.A portion 23 of the toothing of the wheel 18 protrudes from the housing 11 so as to be able to be engaged in the toothing of a conjugated wheel 24 (FIG. 2) forming part of the control system of the bolts such as 9 and 10. The mechanism for transmitting and transforming the rotational movement of the wheel 24 into an appropriate translational movement of the bolts 9 and 10 is not shown in the drawings. All of these mechanisms are covered by a casing 25 fixed against the door.

A partir des explications qui précèdent, on comprend que le bloc 11 est facilement interchange­able. Après démontage du carter 25, il suffit de retirer les vis 22 et de dégager l'ensemble du bloc 11 du reste du système de commande M des pênes, par mouvement de translation perpendiculaire à la porte 2 pour dégager le bloc 11 dont la sûreté extérieure 4 traverse un trou 26 prévu dans ladite porte 2.From the above explanations, it is understood that the block 11 is easily interchangeable. After dismantling the casing 25, it suffices to remove the screws 22 and to release the whole of the block 11 from the rest of the control system M of the bolts, by translational movement perpendicular to the door 2 to release the block 11, the external safety of which 4 passes through a hole 26 provided in said door 2.

Les opérations inverses permettent d'effectuer, rapidement, le montage d'un autre bloc.Reverse operations allow you to quickly assemble another block.

Il est à noter que l'organe d'entraînement constitué par une roue dentée 18 dans l'exemple considéré, pourrait être réalisé sous une autre forme, par exemple sous la forme d'un doigt ou analogue. Il suffit que cet organe d'entraînement soit agencé de manière à entrer en coopération avec le système de commande M ou à en être séparé par une simple transla­tion suivant une direction perpendiculaire au plan de la porte 2.It should be noted that the drive member constituted by a toothed wheel 18 in the example considered, could be produced in another form, for example in the form of a finger or the like. It suffices that this drive member is arranged so as to enter into cooperation with the control system M or to be separated from it by a simple translation in a direction perpendicular to the plane of door 2.

Les stators 5, 6 sont de préférence constitués par des cylindres à section transversale circulaire, comme visible notamment sur la figure 2, présentant une grande résistance à l'effraction, les axes des stators 5 et 6, ainsi que ceux des rotors étant alignés.The stators 5, 6 are preferably constituted by cylinders of circular cross section, as visible in particular in FIG. 2, having a high resistance to burglary, the axes of the stators 5 and 6, as well as those of the rotors being aligned.

De préférence, les rotors 7 et 8 commandent un seul et même organe entraîneur 27 (voir figures 3 à 6) situé dans le logement 19 du boîtier 12 et monté rotatif coaxialement au rotor.Preferably, the rotors 7 and 8 control a single driving member 27 (see Figures 3 to 6) located in the housing 19 of the housing 12 and rotatably mounted coaxially with the rotor.

Cet organe entraîneur 27 est constitué par une sorte de manchon et comporte, sensiblement à mi-­longueur, une paroi 28, orthogonale à son axe, séparant l'intérieur du manchon en deux compartiments 29, 30. L'organe 27 est muni extérieurement, à son extrémité tournée vers la sûreté intérieure 3, d'un pignon 31 propre à engrener avec la roue dentée 23. Le diamètre du pignon 31 est inférieur à celui de la roue dentée 23 ; le mécanisme d'entraînement 13 ainsi formé introduit une démultiplication au niveau de la roue 23.This driving member 27 is constituted by a kind of sleeve and comprises, substantially at mid-length, a wall 28, orthogonal to its axis, dividing the interior of the sleeve into two compartments 29, 30. The member 27 is provided externally, at its end facing internal security 3, of a pinion 31 suitable for meshing with the toothed wheel 23. The diameter of the pinion 31 is less than that of the toothed wheel 23; the drive mechanism 13 thus formed introduces a reduction in the level of the wheel 23.

Une pièce extérieure 32 et une pièce intérieure 33, liées au rotor respectif 8, 7, sont montées tournantes dans chaque compartiment 29, 30 de l'organe 27.An outer part 32 and an inner part 33, linked to the respective rotor 8, 7, are rotatably mounted in each compartment 29, 30 of the member 27.

Des moyens de couplage C sont prévus du côté intérieur et du côté extérieur pour établir une liaison en rotation entre l'organe 27 et le rotor 7, 8 dans lequel une clé est engagé. Ces moyens de couplage C sont agencés pour permettre d'actionner la serrure de l'extérieur alors que la clé n'est pas retirée de la serrure du côté intérieur et que la serrure ne se trouve pas en position de repos.Coupling means C are provided on the inside and on the outside to establish a rotational connection between the member 27 and the rotor 7, 8 in which a key is engaged. These coupling means C are arranged to allow the lock to be actuated from the outside while the key is not withdrawn from the lock on the inside and the lock is not in the rest position.

Ces moyens de couplage C comprennent, du côté de la sûreté intérieure 3, un mobile intérieur 34, formé par une sorte de pion cylindrique d'axe parallèle à celui du rotor 7. Ce mobile 34 est monté coulissant dans un logement traversant complètement la pièce tournante 33. Le mobile 34 comporte un pro­longement 35, de plus faible diamètre, qui fait sail­lie dans le logement du rotor 7. Lorsqu'une clé 36 (voir figure 4) est introduite dans ce logement du rotor 7, elle est propre à venir pousser ce prolonge­ment 35 en fin d'introduction.These coupling means C comprise, on the internal safety side 3, an internal mobile 34, formed by a sort of cylindrical pin with an axis parallel to that of the rotor 7. This mobile 34 is slidably mounted in a housing completely passing through the part. rotating 33. The mobile 34 has an extension 35, of smaller diameter, which projects into the housing of the rotor 7. When a key 36 (see FIG. 4) is inserted into this housing of the rotor 7, it is able to come push this extension 35 at the end of introduction.

La paroi intermédiaire 28 (voir également figure 7) comporte un passage 37 dont la section transversale est identique à celle du mobile 34 de telle sorte que ce mobile puisse être poussé dans ce passage, par la clé 36, pour assurer une liaison en rotation entre le rotor 7 et l'organe entraîneur 27. Ceci est possible lorsque la position angulaire rela­tive du rotor 7 et de l'organe entraîneur 27 est correcte.The intermediate wall 28 (see also Figure 7) has a passage 37 whose cross section is identical to that of the mobile 34 so that this mobile can be pushed into this passage, by the key 36, to ensure a connection in rotation between the rotor 7 and the driving member 27. This is possible when the relative angular position of the rotor 7 and the driving member 27 is correct.

Un organe de condamnation 38, constitué par un pion cylindrique d'axe parallèle à celui du rotor 8, est prévu du côté de la pièce tournante extérieure 32. L'axe de cet organe de condamnation 38 est situé à la même distance radiale de l'axe commun des rotors 7 et 8, que l'axe du mobile 34. L'organe de condamnation 38 a même section transversale que le mobile 34. L'extrémité de l'organe 38 tournée vers le mobile 34 a une forme arrondie en calotte sphérique.A locking member 38, consisting of a cylindrical pin with an axis parallel to that of the rotor 8, is provided on the side of the outer rotating part 32. The axis of this locking member 38 is located at the same radial distance from the common axis of the rotors 7 and 8, as the axis of the mobile 34. The locking member 38 has the same cross section as the mobile 34. The end of the member 38 facing the mobile 34 has a rounded shape spherical cap.

L'organe de condamnation 38 est monté coul­issant dans un alésage de la pièce 32 et est sollicité élastiquement par un ressort 39, notamment en hélice, qui le repousse vers la pièce 33. L'extrémité arron­die de cet organe 38 s'engage dans le passage 37 lorsque la position angulaire relative de la pièce 32 et de l'organe entraîneur 27 le permet. Le ressort 39 est en appui, à son extrémité éloignée de l'organe 38, contre un organe détecteur de clé 40 monté coulissant dans le logement du rotor extérieur 8. Ce détecteur 40 est formé par une sorte de barrette présentant, sur sa face tournée radialement vers l'intérieur du rotor, une échancrure longitudinale 41, limitée à ses deux extrémités par des rebords 42, 43.The locking member 38 is slidably mounted in a bore of the part 32 and is resiliently biased by a spring 39, in particular in a helix, which pushes it towards the part 33. The rounded end of this member 38 engages in the passage 37 when the relative angular position of the part 32 and of the driving member 27 allows it. The spring 39 is in abutment, at its end remote from the member 38, against a key detector member 40 slidably mounted in the housing of the outer rotor 8. This detector 40 is formed by a sort of bar having, on its turned side radially inward of the rotor, a longitudinal notch 41, limited at its two ends by flanges 42, 43.

Le rebord 42 le plus proche du boîtier 11 sert de butée à un cran de retenue 44 prévu sur une extrémité d'un organe d'embrayage 45 comprenant deux parties longitudinales décalées radialement l'une par rapport à l'autre de sorte que l'ensemble de l'organe 45 a sensiblement la forme d'un S stylisé. L'organe est guidé en coulissement suivant une direction parallèle à l'axe du rotor 8, dans un logement 46 de la pièce extérieure 32 ; ce logement 46 débouche par une fenêtre 47 vers la paroi intermédiaire 28. La sec­tion transversale de cette fenêtre 47, identique à celle de l'organe d'embrayage 45 a sensiblement une forme rectangulaire dont les petits côtés sont remplacés par des arcs de cercle convexes. Cette sec­tion transversale est identique à celle d'un passage 48 (voir figure 7) prévu, à la même position radiale, dans la paroi 28. Les formes et les dimensions du passage 48 et du passage 37 sont telles que l'organe de condamnation 38 et le mobile 34 ne peuvent pénétrer dans le passage 48, tandis que l'extrémité de l'organe d'embrayage 45 ne peut pénétrer dans le passage 37.The flange 42 closest to the housing 11 serves as a stop for a retaining notch 44 provided on one end of a clutch member 45 comprising two longitudinal parts offset radially with respect to each other so that the assembly of the member 45 has substantially the shape of a stylized S. The member is guided in sliding in a direction parallel to the axis of the rotor 8, in a housing 46 of the outer part 32; this housing 46 opens through a window 47 towards the intermediate wall 28. The cross section of this window 47, identical to that of the clutch member 45 has substantially rectangular shape whose short sides are replaced by convex arcs. This cross section is identical to that of a passage 48 (see FIG. 7) provided, in the same radial position, in the wall 28. The shapes and dimensions of the passage 48 and of the passage 37 are such that the locking member 38 and the mobile 34 cannot enter the passage 48, while the end of the clutch member 45 cannot enter the passage 37.

A son extrémité éloignée de la paroi 28, et déportée radialement vers l'intérieur, la pièce d'embrayage 45 est poussée par un ressort 49 de sorte que son cran 44 vient en butée contre le rebord 42.At its end remote from the wall 28, and offset radially inwards, the clutch part 45 is pushed by a spring 49 so that its notch 44 abuts against the flange 42.

L'organe d'embrayage 45 a une position angu­laire décalée de 180° par rapport à l'organe de con­damnation 38 ; les passages 37 et 48 sont également décalés de 180° (voir figure 7). Le décrochement radial extérieur 50 de la pièce d'embrayage 45 sert de butée, contre la face interne du foncet 20, retenant ledit organe d'embrayage dans le logement 46 à l'encontre de l'effort du ressort 39.The clutch member 45 has an angular position offset by 180 ° relative to the locking member 38; passages 37 and 48 are also offset by 180 ° (see figure 7). The external radial offset 50 of the clutch part 45 serves as a stop against the internal face of the bolt 20, retaining said clutch member in the housing 46 against the force of the spring 39.

L'organe détecteur 40, notamment au niveau de la longueur de son échancrure 41, l'organe d'embrayage 45 et les ressorts 39 et 49 sont agencés de manière à permettre qu'une clé 51 (figure 5) soit complètement introduite dans le logement du rotor extérieur 8 alors que l'organe de condamnation 38 et l'organe d'embrayage 45 sont en appui contre la paroi 28 (figure 5).The detector member 40, in particular at the level of the length of its notch 41, the clutch member 45 and the springs 39 and 49 are arranged so as to allow a key 51 (FIG. 5) to be completely inserted into the housing of the outer rotor 8 while the locking member 38 and the clutch member 45 are in abutment against the wall 28 (Figure 5).

Ceci étant, le fonctionnement de la serrure des figures 3 à 6 est le suivant.That said, the operation of the lock of Figures 3 to 6 is as follows.

Au repos, c'est-à-dire lorsqu'aucune clé n'est introduite dans l'un des rotors 7 ou 8, le mobile intérieur 34 et l'organe de condamnation 38 sont alignés. Cet organe 38 est engagé par son extrémité dans le passage 37, le ressort 39 étant détendu et ayant sa longueur maximale. L'organe entraîneur 27 est liée en rotation, par l'organe de condamnation 38 à la pièce extérieure 32 et au rotor extérieur 8.At rest, that is to say when no key is inserted into one of the rotors 7 or 8, the inner mobile 34 and the locking member 38 are aligned. This member 38 is engaged by its end in the passage 37, the spring 39 being relaxed and having its maximum length. The driving member 27 is linked in rotation, by the locking member 38 to the external part 32 and to the external rotor 8.

Si une clé 36 est engagée dans le logement du rotor intérieur 7 (voir figure 4), en fin d'introduction cette clé repousse le mobile 34 qui s'engage dans le passage 37 en repoussant l'organe de condamnation 38. Une liaison en rotation est établie entre l'organe entraîneur 27 et le rotor 7 par le mobile 34, alors que cet organe entraîneur 27 est libéré en rotation par rapport au rotor extérieur 8.If a key 36 is engaged in the housing of the inner rotor 7 (see Figure 4), at the end of introduction this key pushes the mobile 34 which engages in the passage 37 by pushing the locking member 38. A connection in rotation is established between the driving member 27 and the rotor 7 by the mobile 34, while this driving member 27 is released in rotation relative to the external rotor 8.

La rotation de la clé 36 permet d'entraîner la roue 18 et donc la roue 24 et le système de com­mande M (figure 2) des pênes 9 et 10.The rotation of the key 36 makes it possible to drive the wheel 18 and therefore the wheel 24 and the control system M (FIG. 2) of the bolts 9 and 10.

La figure 5 représente la serrure dans une position où la clé 36 est tournée d'un angle quel­conque, par exemple d'environ 90°, par rapport à la figure 4. Malgré cette configuration, il est possi­ble, avec le dispositif de l'invention, de commander la serrure de l'extérieur à l'aide de la clé 51, comme expliqué ci-après.Figure 5 shows the lock in a position where the key 36 is rotated by any angle, for example about 90 °, relative to Figure 4. Despite this configuration, it is possible, with the device of invention, to control the lock from the outside using the key 51, as explained below.

En introduisant cette clé 51 dans le loge­ment du rotor 8, on pousse le détecteur de clé 40 et on comprime les ressorts 39 et 49. Du fait que l'organe entraîneur 27 a tourné avec la clé 36 par rapport à la position de la figure 4, l'organe de con­damnation 38 et l'organe de débrayage 45 ne se trouvent plus en face de leurs passages respectifs 37 et 48. Les extrémités de ces organes sont donc poussés élastiquement contre la paroi 28.By inserting this key 51 into the housing of the rotor 8, the key detector 40 is pushed and the springs 39 and 49 are compressed. Because the driving member 27 has rotated with the key 36 relative to the position of the figure 4, the locking member 38 and the declutching member 45 are no longer located opposite their respective passages 37 and 48. The ends of these members are therefore pushed elastically against the wall 28.

La pièce extérieure 32 étant libre par rap­port à l'organe entraîneur 27, il est possible de faire tourner le rotor 8 et cette pièce 32 avec la clé 51 jusqu'à ce que l'extrémité de la pièce d'embrayage 45 vienne en regard du passage 48.The outer part 32 being free relative to the driving member 27, it is possible to rotate the rotor 8 and this part 32 with the key 51 until the end of the clutch part 45 comes opposite from passage 48.

Lorsque cette position angulaire est atteinte, comme représenté sur la figure 6, le ressort 49 se détend légèrement en poussant la pièce d'embrayage 45 de sorte que l'extrémité de cette pièce pénètre dans le passage 48 et établit une liaison en rotation entre la pièce 32 et donc le rotor extérieur 8, et l'organe entraîneur 27. Il est maintenant possi­ble d'entraîner, à l'aide de la clé 51, ledit organe entraîneur 27 et le système de commande M de la ser­rure.When this angular position is reached, as shown in FIG. 6, the spring 49 slightly relaxes by pushing the clutch part 45 so that the end of this part enters the passage 48 and establishes a connection in rotation between the part 32 and therefore the outer rotor 8, and the drive member 27. It is now possible to drive, using the key 51, said drive member 27 and the control system M of the lock.
