Description

La présente invention se réfère, à un nouveau système de sûreté par fermeture à blocage par chiffre dont l'ensemble est applicable à tout genre de portes, y compris celles de coffres-forts ou coffres de sécurité. The present invention refers to a new security system by digitally locked closure, the assembly of which is applicable to all kinds of doors, including those of safes or safety deposit boxes.

La fermeture selon l'invention présente, entre autres, l'avantage d'empêcher que l'on puisse déterminer, à l'aide de moyens acoustiques, le chiffre programmé pour l'ouverture d'un coffre-fort, et celui de ne pas permettre son changement de combinaison ou déblocage tant que le pêne se trouve en position de blocage. Cette fermeture n'est sujette à aucun effort mécanique important, dans la mesure où sa mission est de bloquer le mécanisme d'ouverture des portes lorsque celles-ci doivent se trouver fermées, le déblocage ayant un lieu au moment de l'ouverture de celles-ci par actionnement de séries de leviers et de verrous normalement mus par un volant ou levier aux dimensions appropriées. The closure according to the invention has, inter alia, the advantage of preventing one being able to determine, by means of acoustic means, the figure programmed for the opening of a safe, and that of not not allow its change of combination or release as long as the bolt is in the locking position. This closure is not subject to any significant mechanical effort, insofar as its mission is to block the mechanism for opening the doors when these must be closed, the unlocking taking place at the time of opening those -this by actuation of series of levers and latches normally moved by a wheel or lever with the appropriate dimensions.

Le fonctionnement de la serrure selon l'invention consiste à déplacer, dans un certain ordre, une série d'engrenages ou crémaillères d'un nombre de pas préétabli et, partant, à faire tourner une série de disques dentés de grandeurs angulaires proportionnelles aux déplacements linéaires des crémaillères. Le déplacement doit être tel que le cran ou mortaise radial qu'elles présentent toutes sur leur pourtour coïncide avec un taquet ou tenon qui, dans cette position, s'introduit en déplaçant une pièce qui joue le rôle d'arrêtoir ou de butée et bloque le mouvement du verrou normal d'ouverture où est montée la serrure faisant l'objet de l'invention. The operation of the lock according to the invention consists in moving, in a certain order, a series of gears or racks of a predetermined number of steps and, consequently, in rotating a series of toothed discs of angular magnitudes proportional to the displacements linear racks. The displacement must be such that the radial notch or mortise which they all have on their periphery coincides with a cleat or tenon which, in this position, is introduced by moving a part which acts as a stopper or stop and blocks the movement of the normal opening lock where the lock forming the subject of the invention is mounted.

L'actionnement de la serrure s'effectue comme suit
L'axe de commande (1) guidé par la bague guide (7a) présente sur la partie médiane et intérieure de la bague (7a) une série de crans ou mortaises ou positions déplacées angulairement sur son pourtour et parallèles les uns aux autres, sur lesquels repose un nombre égal de cliquets de composition ou chiffrage (5) comprimés contre eux au moyen de ressorts unitaires guidés sur la pompe d'entraînement (4). Chaque position de l'axe de commande (1) rapproche l'un des cliquets de chiffrage (5) du cran ou mortaise correspondant, de sorte que, par basculement, la griffe se trouvant au bout de ceux-ci s'enclenche à la crémaillère correspondante.In this description, the reference numbers have the following meanings
1 is a control pin, 2 is a push rod, 3 is a drive pump cover, 4 is a drive pump, 5 is a ratchet for composition or encryption, 6 is a rack, 7 is a cream guide llère, 7a is a control shaft guide ring, 8 is a core or body, 9 is a lower core cover, 10 is an upper core cover, 11 is a tilting support, 12 is a rocker or rocker, 13 is a casing racks, 14 are racks, 15 is a rack gripper, 16 is a rack housing, 17 is an opening lever, 18 is a rack housing cover, 19 is a triangle cover or lid, 20 is a screw cover, 21 is an erasing lever or cam, 22 is a retaining pawl, 23 is a changing spring, 24 is a retaining pump, 25 is a changing lever, 26 is a protective wheel screw, 27 is a cleat or nipple lever, 28 is a wheel support, 29 are wheels, 30 is a cover or safety catch shield swimming, 30a is a screw fixing cover safety catch gear or snap-fastening, 31 is a safety catch gear or snap-fastening, 32 are height feet, 33 is a bolt box, 34 is a bolt, 35 are bolt springs, 36 is a gripper bolt, 37 are stops or latch bolts, 38 is a lower cover, bolt housing, 39 is a key change safety catch
The actuation of the lock is carried out as follows
The control axis (1) guided by the guide ring (7a) has on the central and inner part of the ring (7a) a series of notches or mortises or positions angularly displaced around its periphery and parallel to each other, on which rests an equal number of pawls of composition or encryption (5) compressed against them by means of unit springs guided on the drive pump (4). Each position of the control shaft (1) brings one of the encryption pawls (5) closer to the corresponding notch or mortise, so that, by tilting, the claw at the end of these engages with the corresponding rack.

L'actionnement par pressions sur l'axe cylindrique (2) ou poussoir passant à l'intérieur de l'axe de commande (1) affecte le basculeur (12) en transmettant, au moyen de ses bras qui s'engrènent à la pompe d'entra;- nement (4), solidaire de la crémaillère (6), un mouvement de déplacement de l'ensemble des cliquets de chiffrage (5), tout en déplaçant la crémaillère (14) correspondante qui, à sont tour, fait se déplacer angulairement l'une des roues dentées (29) à laquelle elle est engrenée. The actuation by pressure on the cylindrical axis (2) or pusher passing inside the control axis (1) affects the rocker (12) by transmitting, by means of its arms which mesh with the pump entra - - nement (4), integral with the rack (6), a movement of displacement of the set of encryption pawls (5), while moving the corresponding rack (14) which, in turn, made angularly move one of the toothed wheels (29) to which it is meshed.

L'ensemble des crémaillères déplacées est retenu par des cliquets inférieurs de retenue (22) actionnés par la pompe de retenue (24) et libérés au dernier point de sélection du pêne par la griffe du levier d'effacement (21), ce qui fait que toutes les crémaillères reviennent en position de fin de course en entraînant les roues (29) correspondantes. The set of displaced racks is retained by lower retaining pawls (22) actuated by the retaining pump (24) and released at the last bolt selection point by the claw of the erasing lever (21), which makes that all the racks return to the end of travel position by driving the corresponding wheels (29).

Au moment de la sélection du chiffre, l'on introduit du côté intérieur de la serrure une clé au-travers du guide et du boîtier du pêne (33), qui déplace par rotation partielle le support de roues (28) et le cran de sûreté de l'engrenage (31), lequel retient en position d'ouverture le pêne (34), en déverrouillant ainsi les roues (29) des crémaillères (14). When the number is selected, a key is inserted on the inside of the lock through the guide and the bolt housing (33), which moves the wheel support (28) and the notch by partial rotation safety of the gear (31), which retains the bolt (34) in the open position, thereby unlocking the wheels (29) of the racks (14).

Le chiffrage de chaque position déplacera alors les crémaillères et, en position finale de déblocage, le cran de sûreté de l'engrenage (31) libèrera le pêne (34), levier ou came d'effacement (21) agissant sur les cliquets de retenue (22) et libérant les crémaillères (14) qui entraînent dans leur déplacement les roues (29), ces dernières demeurant en positions déphasées angulairement proportionnellement aux pas sélectionnés à chaque position. The encryption of each position will then move the racks and, in the final unlocking position, the safety catch of the gear (31) will release the bolt (34), lever or erasing cam (21) acting on the retaining pawls (22) and releasing the racks (14) which drive the wheels (29) in their displacement, the latter remaining in angularly phase shifted positions in proportion to the steps selected at each position.

La répétition de la combinaison ou chiffre permet
tra que le levier taquet (27) pénètre dans les roues (29) en libérant le pêne (34).Repeating the combination or number allows
tra that the cleat lever (27) enters the wheels (29) by releasing the bolt (34).

En position de fermeture, le levier cran de sûreté clé (39) obture partiellement par basculement l'orifice d'entrée en n'en permettant pas l'accès. In the closed position, the key safety catch lever (39) partially closes the inlet orifice by not allowing access to it.
