Cylinder lock with a catch provided with an integral housing (1) containing the internal and external opening mechanisms (9, 17) comprising on their internal part projecting outside of the housing a peripheral groove (24) and which can be rotated one with another by mechanical means, characterized in that the mechanical means are provided with the catch (25) comprising a case containing at least two removable shells (27) which are held in their operational position against each other by the case, these shells comprising ribs (28) fitted in said grooves (24).

Description

La présente invention a pour objet une serrure à cylindre avec panneton, comportant un bâti monolytique renfermant les mécanismes d'ouverture interne et externe qui comportent, sur leur partie interne faisant saillie hors du bâti, une rainure périphérique, et qui sont susceptibles d'être entraînés en rotation l'un avec l'autre par un moyen mécanique, ce dernier verrouillant aussi la position axiale relative des deux mécanismes d'ouverture et de fermeture de la serrure.The present invention relates to a cylinder lock with bit, comprising a monolytic frame containing the internal and external opening mechanisms which comprise, on their internal part projecting from the frame, a peripheral groove, and which are capable of being driven in rotation with each other by mechanical means, the latter also locking the relative axial position of the two mechanisms for opening and closing the lock.

Le brevet suisse No. 336 289 décrit une serrue à cylindre de ce type avec panneton (104), comportant un bâti monolytique (101) renfermant les mécanismes d'ouverture interne et externe (102a, 102b) qui comportent, sur leur partie interne faisant saillie hors du bâti, une rainure (122a, b) périphérique. Ces méchanismes sont susceptibles d'être entraînés en rotation l'un avec l'autre par un moyen mécanique (107) qui verrouille aussi la position axiale relative des deux mécanismes d'ouverture de la serrure.Swiss Patent No. 336,289 describes a cylinder lock of this type with bit (104), comprising a monolytic frame (101) enclosing the internal and external opening mechanisms (102a, 102b) which comprise, on their internal part forming protruding from the frame, a peripheral groove (122a, b). These mechanisms are capable of being rotated with each other by mechanical means (107) which also locks the relative axial position of the two opening mechanisms of the lock.

Les serrures à cylindres connues comportent habituellement des moyens des montage relativement fragiles. En outre, les cylindrés émergent souvent hors de l'épaisseur de la porte, de sorte qu'il est facile, à l'aide de pinces, d'arracher le cylindre extérieur pour accéder au panneton, ce qui permet d'ouvrir aisément la porte.Known cylinder locks usually have relatively fragile mounting means. In addition, the displacements often emerge out of the thickness of the door, so that it is easy, using pliers, to tear off the outer cylinder to access the bit, which makes it easy to open the door.

La présente invention a pour objet une serrure à cylindre tendant à obvier aux inconvénients précités.The present invention relates to a cylinder lock tending to obviate the aforementioned drawbacks.

Ce but est atteint part une serrure selon l'invention, caractérisée en ce que ledit moyen mécanique est constitué par le panneton lui-même, qui comporte une cage renfermant au moins deux coquilles amovibles qui sont maintenues l'une contre l'autre par la cage lorsque la serrure est en service, ces coquilles comportant des nervures engagées dans lesdites rainures.This object is achieved by a lock according to the invention, characterized in that said mechanical means consists of the bit itself, which comprises a cage containing at least two removable shells which are held one against the other by the cage when the lock is in service, these shells having ribs engaged in said grooves.

La serrure illustrée aux figures 1 à 5 est une serrure à deux cylindres s'ouvrant donc de l'intérieur comme de l'extérieur à l'aide d'une clé.The lock illustrated in FIGS. 1 to 5 is a lock with two cylinders therefore opening from the inside as from the outside using a key.

Cette serrure comporte un bâti monolytique 1, constitué en une seule pièce de fabrication, comportant deux extensions 2,3 interne respectivement externe, reliées par trois ponts 4. Dans une variante les trois ponts 4 pourraient être reliés, seule une ouverture médiane subsistant pour le positionnement du panneton comme on le verra plus loin.This lock comprises a monolytic frame 1, made up of a single workpiece, comprising two internal and external extensions 2.3, connected by three bridges 4. In a variant, the three bridges 4 could be connected, only one central opening remaining for the positioning of the bit as will be seen below.

Chaque extension du bâti 1 renferme un mécanisme d'ouverture à clé de sécurité comprenant des contre-poussoirs 5 de différentes longueurs, soumis à l'action de ressorts 6, logés dans des perçages 7 parallèles à l'axe du bâti.Each extension of the frame 1 contains an opening mechanism with a security key comprising counter-pushers 5 of different lengths, subjected to the action of springs 6, housed in holes 7 parallel to the axis of the frame.

Les perçages 7 débouchent dans un chambrage 8 de l'extension 2,3 correspondant dans lequel est logé un cylindre 9 et dans le perçage central 10 du bâti.The holes 7 open into a recess 8 of the corresponding extension 2.3 in which a cylinder 9 is housed and into the central bore 10 of the frame.

Le cylindre 9 comporte un perçage axial 11 relié par des rainures radiales 12 à des perçages longitudinaux 13 correspondant aux perçages 7 du bâti 1. Des poussoirs 14 sont placés dans ces perçages 13 et butent contre les contre-poussoirs 5. Ces poussoirs ont un bec 15 pénétrant dans la rainures radiale 12 correspondante. Les perçages 11 ne débouchent pas sur la face externe du cylindre 9, en acier fritté, de sorte qu'en position de repos tous les poussoirs 14 sont en contact avec un épaulement 16 et toutes les interfaces, poussoirs 17-contre-poussoirs 5 sont disposés dans les perçages 13 du cylindre 9.The cylinder 9 has an axial bore 11 connected by radial grooves 12 to longitudinal bores 13 corresponding to the bores 7 of the frame 1. Pushers 14 are placed in these bores 13 and abut against the pushers 5. These pushers have a spout 15 penetrating into the corresponding radial grooves 12. The holes 11 do not open onto the external face of the cylinder 9, made of sintered steel, so that in the rest position all the pushers 14 are in contact with a shoulder 16 and all the interfaces, pushers 17-against pushers 5 are arranged in the holes 13 of the cylinder 9.

Ce cylindre 9 est ainsi solidaire en rotation du bâti 1. Le cyclindre 9 est vissé sur une douille 17 et fixé définitivement à celle-ci au montage à l'aide d'une goupille 18. Un élément d'entraînement 19 est monté coulissant dans cette douille 17 et est soumis à l'action d'un ressort 20 tendant à le déplacer en direction du cylindre 9.This cylinder 9 is thus integral in rotation with the frame 1. The cylinder 9 is screwed onto a bushing 17 and definitively fixed thereto for mounting by means of a pin 18. A drive element 19 is slidably mounted in this socket 17 and is subjected to the action of a spring 20 tending to move it in the direction of the cylinder 9.

Le cylindre 9 comporte dans sa paroi périphérique un perçage 21 dans lequel est logée une bille 22 qui en position de repos du cylindre est partiellement engagée dans une cavité 23 de l'extension 2, 3. Dans une variante cette bille peut être remplacée par une goupille dont l'une des extrémités coopére avec ladite cavité de l'extension et l'autre avec un logement de la clé comme décrit plus loin.The cylinder 9 has in its peripheral wall a bore 21 in which is housed a ball 22 which in the rest position of the cylinder is partially engaged in a cavity 23 of the extension 2, 3. In a variant this ball can be replaced by a pin, one of the ends of which cooperates with said extension cavity and the other with a housing for the key as described below.

La partie frontale libre des douilles 17 présente une gorge annulaire extérieure 24. Au montage, le bâti 1 est mis en place sur le vantail d'une porte puis un panneton comportant une cage 25 munie de son organe d'actionnement 26 est placé entre les deux extensions 2, 3. Ce panneton comporte deux ou plusieurs coquilles 27 qui en position écartée (figure 5) peuvent donner passage aux douilles 17. Les mécanismes d'ouverture 9, 17 sont alors mis en place et les extrémités frontales des douilles 17 sont engagées dans le panneton entre les coquilles 27. Lorsque des nervures 28 de ces coquilles 27 sont en regard des rainures 24 des douilles 17, les coquilles sont rapprochées. La cage du panneton 25 est alors déplacée angulaire- ment par rapport aux coquilles 27 bloquant celles-ci en position rapprochée par les renflements intérieurs 29 prenant appui contre la face externe 30 des coquilles 27. A cet instant un doigt 31 coulissant sous l'action d'un ressort 32 dans un logement de l'organe de manoeuvre 26 du panneton 25 s'engage dans un perçage 33 d'une des coquilles 27 bloquant ainsi le panneton en position resserrée des coquilles. Dès cet instant les deux mécanismes d'ouverture 9,17 sont solidaires l'un de l'autre et ne peuvent plus se déplacer axialement l'un par rapport à l'autre.The free front part of the sockets 17 has an external annular groove 24. On mounting, the frame 1 is placed on the leaf of a door and then a bit comprising a cage 25 provided with its actuating member 26 is placed between the two extensions 2, 3. This bit comprises two or more shells 27 which in the separated position (FIG. 5) can give way to the sockets 17. The opening mechanisms 9, 17 are then put in place and the front ends of the sockets 17 are engaged in the bit between the shells 27. When the ribs 28 of these shells 27 are opposite the grooves 24 of the sockets 17, the shells are brought together. The bit 25 cage is then moved angularly relative to the shells 27 blocking these in close position by the internal bulges 29 bearing against the external face 30 of the shells 27. At this instant a finger 31 sliding under the action of a spring 32 in a housing of the operating member 26 of the bit 25 engages in a bore 33 of one of the shells 27 thus blocking the bit in the constricted position of the shells. From this moment the two opening mechanisms 9,17 are integral with each other and can no longer move axially relative to each other.

Comme le doigt 31 peut être placé dans les perçages 32 de l'une ou l'autre des coquilles 27 le même mécanisme peut être utilisé pour une serrure à droite ou à gauche.As the finger 31 can be placed in the holes 32 of one or the other of the shells 27 the same mechanism can be used for a lock on the right or on the left.

Même une fois monté, les mécanismes d'ouverture étant reliés par les coquilles du panneton, il est possible de tourner de 180° ce panneton. En introduisant un tournevis entre les tiges d'entraînement 20, on désolidarise en rotation le panneton des cylindres.Even once assembled, the opening mechanisms being connected by the shells of the bit, it is possible to turn 180 ° this bit. By introducing a screwdriver between the drive rods 20, the bit from the cylinders is disconnected in rotation.

La clé comporte un corps cylindrique 34 muni d'extensions radiales 35 s'étendant sur des hauteurs différentes à partir de l'extrémité de la clé, destinées à coopêrer avec les becs 15 des poussoirs 14. Lorsque la bonne clé est utilisée et qu'elle est introduite à fond dans le cylindre elle pousse l'organe d'entraînement 19 dans le panneton entre ses coquilles 27 qui présentent des formations à cet effet solidarisant ainsi le cylindre 9 et la panneton 25.The key comprises a cylindrical body 34 provided with radial extensions 35 extending over different heights from the end of the key, intended to cooperate with the spouts 15 of the pushers 14. When the correct key is used and that it is fully inserted into the cylinder; it pushes the drive member 19 into the bit between its shells 27 which have formations for this purpose thus joining the cylinder 9 and the bit 25.

Simultanément tous les poussoirs 14 sont refoulés jusque dans une position pour laquelle l'interface entre ces poussoirs et les contre-poussoirs 5 est située dans le plan séparant la face frontale du cylindre 9 du fond du logement 11 de l'extension 2, 3 ce qui libère le cylindre en rotation par rapport au bâti 1.Simultaneously all the pushers 14 are pushed back into a position for which the interface between these pushers and the counter pushers 5 is located in the plane separating the front face of the cylinder 9 from the bottom of the housing 11 of the extension 2, 3 ce which releases the cylinder in rotation relative to the frame 1.

L'usager peut alors tourner la clé pour ouvrir la serrure. Il faut noter que la clé présente au droit de la bille ou de la goupille 22 un logement 34 de sorte que pour la moindre rotation de la clé, la bille 22 sort de la cavité 23 et entre dans le logement 34 interdisant tout retrait de la clé hors de la serrure.The user can then turn the key to open the lock. It should be noted that the key has at the right of the ball or the pin 22 a housing 34 so that for the slightest rotation of the key, the ball 22 leaves the cavity 23 and enters the housing 34 preventing any removal of the key out of the lock.

La serrure décrite ne peut plus être fracturée par arrachement du cylindre extérieur puisque le bâti de la serrure est en une seule pièce, comprenant au moins deux ou trois ponts et que d'autre part les mécanismes d'ouverture interne et externe sont eux mêmes reliés mécaniquement de manière à empêcher tout déplacement axial de l'un par rapport à l'autre.The lock described can no longer be fractured by tearing off the outer cylinder since the frame of the lock is in one piece, comprising at least two or three bridges and that on the other hand the internal and external opening mechanisms are themselves connected mechanically so as to prevent any axial displacement of one relative to the other.

Dans la seconde forme d'exécution de la serrure illustrée aux figures 6 à 8 le mécanisme d'ouverture à cylindre interne est remplacé par un mécanisme à bouton. Le reste de la serrure est pratiquement le même que ce qui a été décrit précédemment et les mêmes chiffres de référence indiquent les parties correspondantes.In the second embodiment of the lock illustrated in FIGS. 6 to 8, the internal cylinder opening mechanism is replaced by a button mechanism. The rest of the lock is practically the same as described above and the same reference numerals indicate the corresponding parts.

Le mécanisme d'ouverture à bouton comporte un bouton 35 tourrillonné dans l'extension 3 du bâti 1, prolongé par une partie de plus petit diamètre 36 dont la fonction est similaire à la douille 17 de la première forme d'exécution.The button opening mechanism comprises a button 35 swirling in the extension 3 of the frame 1, extended by a portion of smaller diameter 36 whose function is similar to the socket 17 of the first embodiment.

Une tige d'entraînement 37 est montée coulissante dans l'extrémité frontale du bouton 35 et est soumise à l'action d'un ressort 38. L'extrémité libre de cette tige comporte une fente 39 destinée à coopérer avec le tige d'entraînement 20 du méchanisme à cylindre extérieur.A drive rod 37 is slidably mounted in the front end of the button 35 and is subjected to the action of a spring 38. The free end of this rod has a slot 39 intended to cooperate with the drive rod 20 of the external cylinder mechanism.

Ici également le panneton verrouille axialement les deux mécanismes d'ouverture l'un à cylindre et l'autre à bouton. De plus, les nervures 24 des coquilles 27 situées du côté du mécanisme à bouton comportent un doigt 24a engagé dans la fente 36a de la partie frontale de la tige du bouton 35. De cette façon, le panneton est rendu solidaire en rotation du bouton. Cette solution évite le goupillage habituel effectué au montage des serrures existantes.Here also the bit axially locks the two opening mechanisms, one with a cylinder and the other with a button. In addition, the ribs 24 of the shells 27 located on the side of the button mechanism include a finger 24a engaged in the slot 36a of the front part of the rod of the button 35. In this way, the bit is made integral in rotation with the button. This solution avoids the usual pinning carried out when mounting existing locks.

Cette serrure présente les mêmes avantages de sécurité que celle décrite précédemment.This lock has the same security advantages as that described above.
