Description Description
Titre de L’invention : Verrou avec serrure à goupilles et cassettesTitle of the invention: Bolt with tumbler lock and cassettes
Domaine technique Technical area
L’invention concerne une serrure à goupille avec au moins un boîtier de serrure, au moins un bras de tirage traversant le boîtier de serrure de manière déplaçable linéairement entre une position de blocage et une position de libération et au moins un dispositif de blocage pouvant être débloqué par un actionnement d’une clé, le bras de tirage étant précontraint dans le sens de sa position de blocage. Les puits de goupilles sont compris dans des cassettes interchangeables de telle sorte que l’on puisse changer la clef et la combinaison sans changer toute la serrure. The invention relates to a tumbler lock with at least one lock housing, at least one pull arm extending linearly through the lock housing between a blocking position and a release position and at least one blocking device which can be unlocked by actuation of a key, the pull arm being prestressed in the direction of its locking position. The pin wells are included in interchangeable cassettes so that the key and the combination can be changed without changing the entire lock.
État de la technique State of the art
Les dispositifs de verrouillage sont apparus pratiquement en même temps que la civilisation humaine au cours de la sédentarisation au néolithique. Initialement, les portes étaient fixées avec des verrous qui se présentaient sous la forme de simples tiges de bois qui étaient enfoncées dans des ouvertures dans des montants de la porte. Les Égyptiens ont découvert la serrure à verrou qui est apparue à peu près avant l'an 7000. Comme cette serrure est facile à manipuler, on a eu l'idée de la bloquer avec une goupille mobile en bois. La serrure était née. Afin de déverrouiller cette goupille en bois, un outil en fer a été fabriqué avec une dent au moyen de laquelle la goupille en bois pouvait être soulevée. Il en a découlé que l'outil, s'il présentait plusieurs dents, pourrait soulever plusieurs goupilles en bois. C'est ainsi qu'on a créé la clé. Locking devices appeared almost at the same time as human civilization during Neolithic settlement. Initially doors were secured with latches which were in the form of simple wooden rods which were driven into openings in door jambs. The Egyptians discovered the bolt lock which appeared around before the year 7000. As this lock is easy to handle, the idea was to block it with a movable wooden pin. The lock was born. In order to unlock this wooden pin, an iron tool was made with a tooth by means of which the wooden pin could be lifted. It followed that the tool, if it had several teeth, could lift several wooden pins. This is how we created the key.
Il existe de nombreux types de serrures à clé. Une serrure à garnitures utilise des parois métalliques stationnaires avec des ouvertures de clé dont la configuration doit correspondre à une configuration du panneton de la clé afin que le panneton de la clé puisse être introduit dans la serrure à garniture. Un cadenas est muni de pièces métalliques qui sont montées de manière à pouvoir tourner autour d'un axe de rotation et qui sont amenées à une certaine hauteur par une rotation d'un panneton de clé introduit dans le cadenas. Une serrure à goupilles utilise une rangée de goupilles de blocage de longueurs différentes afin de bloquer une ouverture de la serrure à goupilles sans l'introduction d'une clé adaptée aux goupilles de blocage. Une serrure tubulaire est un type de serrure dans laquelle les goupilles de blocage sont disposées en cercle par rapport à un cylindre. La serrure à pompe est un mécanisme cylindrique qui est muni de plusieurs ailettes indépendantes qui coulissent le long d'un axe du cylindre. There are many types of key locks. A set lock uses stationary metal walls with key openings whose configuration must match a configuration of the key bit in order for the key bit to be inserted into the set lock. A padlock is provided with metal parts which are mounted so as to be able to rotate around an axis of rotation and which are brought to a certain height by rotation of a key bit introduced into the padlock. A tumbler lock uses a row of blocking pins of different lengths to block an opening of the tumbler lock without the introduction of a key suitable for the blocking pins. A lock Tubular is a type of lock in which the locking pins are arranged in a circle relative to a cylinder. The pump lock is a cylindrical mechanism which is fitted with several independent fins which slide along an axis of the cylinder.
Toutes les serrures à clé sont basées sur le principe qu'une clé introduite dans celles- ci, qui peut tourner autour d'un axe orienté perpendiculairement à une direction de déplacement des goupilles, entraîne un rotor sur lequel une dent déplace une goupille de blocage. All key locks are based on the principle that a key inserted into them, which can rotate about an axis oriented perpendicular to a direction of movement of the pins, drives a rotor on which a tooth moves a locking pin .
Pour protéger contre les intrusions, la goupille de blocage est verrouillée. La clé libère la goupille de blocage lors de l'actionnement du rotor. Comme dans le cas d'un cadenas, la clé actionne un rotor qui verrouille ou déverrouille à nouveau un élément de ressort. To protect against intrusion, the locking pin is locked. The key releases the locking pin when operating the rotor. As in the case of a padlock, the key activates a rotor which locks or unlocks a spring element again.
De nombreux brevets ont été déposés pour rendre des serrures de plus en plus sécurisées contre des cambriolages et des tentatives d'effraction. Certains systèmes sont extrêmement exigeants ce qui les rend presque inviolables, mais très coûteux.Many patents have been filed to make locks increasingly secure against burglary and break-in attempts. Some systems are extremely demanding which makes them almost tamper-proof, but very expensive.
Dans le cas de l'ouverture d'un verrouillage à goupilles avec un passe-partout, les goupilles de blocage sont orientées de telle sorte que des espaces entre des goupilles de blocage disposées en une rangée à l'intérieur d'un logement de goupilles de blocage coïncident avec des lignes d'espacement entre le rotor et un stator adjacent. Un cambrioleur utilise un système de serrage pour exercer une force de rotation sur le rotor, et un palpeur pour actionner progressivement les goupilles en utilisant les défauts et les intervalles qui se créent lors de la fabrication d'une pièce mécanique. Des méthodes d'effraction plus brutales consistent à percer le cylindre ou à l'arracher pour accéder à la goupille de blocage ou pour forcer la rotation du rotor afin de pouvoir casser les goupilles de blocage et faire ainsi tourner le rotor. In the case of opening a tumbler pin lock with a master key, the locking pins are oriented such that spaces between locking pins arranged in a row within a pin slot blocks coincide with spacing lines between the rotor and an adjacent stator. A burglar uses a clamping system to exert a rotational force on the rotor, and a feeler to progressively actuate the pins by using the defects and gaps that are created during the manufacture of a mechanical part. More brutal break-in methods involve drilling into the cylinder or tearing it out to gain access to the locking pin or to force the rotation of the rotor in order to be able to break the locking pins and thus rotate the rotor.
Ces méthodes d'effraction se concentrent donc sur l'axe de rotation, le principe de fonctionnement d'un verrouillage à clé. These break-in methods therefore focus on the axis of rotation, the operating principle of a key lock.
La sécurité de serrures visant à empêcher des effractions est basée sur le nombre des goupilles de blocage et/ou leur agencement sur plusieurs plans. Cette complexité conduite souvent à une longueur considérable d'un cylindre de serrure, ce qui exige une grande épaisseur d'une porte qui reçoit une telle serrure, ou une taille considérable d'un cadenas. The security of locks aimed at preventing break-ins is based on the number of locking pins and/or their arrangement on several planes. This complexity often leads to a considerable length of a lock cylinder, which requires a great thickness of a door which receives such a lock, or a considerable size of a padlock.
Des traitements de surface, par exemple un cimentage, et l'utilisation d'alliages très durs ou de rondelles mobiles ralentissent une opération d'effraction par perçage. Toutefois, une combinaison de coups de burin, de perçage et de patience permet le plus souvent de percer le cylindre. Surface treatments, for example cementing, and the use of very hard alloys or moving washers slow down a break-in operation by drilling. However, a combination of chisel blows, drilling and patience can most often break through the cylinder.
L'utilisation de matériaux très résistants permet de ralentir l'entraînement d'un rotor avec une force de rotation élevée, où une pièce métallique est enfoncée dans la cavité de la clé afin de faire tourner progressivement le rotor en détruisant progressivement les goupilles, mais dans ce cas également la patience et la force du manipulateur sont souvent couronnées de succès. The use of high strength materials allows the drive of a rotor to be slowed down with a high rotational force, where a metal part is driven into the key cavity in order to gradually rotate the rotor by gradually destroying the pins, but also in this case the patience and the strength of the manipulator are often crowned with success.
Une invention récente concerne un verrou comprenant au moins une serrure à goupilles qui présente un boîtier de serrure, au moins un verrou tournant disposé à l'intérieur du boîtier de serrure de manière à pouvoir tourner autour d'un axe de rotation entre une position de verrouillage et une position de libération et au moins un dispositif de blocage pouvant être débloqué par un actionnement de la clé, qui présente des goupilles de blocage disposées de manière déplaçable axialement pour bloquer une rotation du verrou tournant se trouvant dans la position de verrouillage. A recent invention relates to a lock comprising at least one tumbler lock which has a lock case, at least one rotary lock arranged inside the lock case so as to be able to rotate around an axis of rotation between a position of locking and a release position and at least one locking device which can be unlocked by actuation of the key, which has locking pins arranged in an axially displaceable manner for locking a rotation of the twistlock which is in the locking position.
Une autre invention récente concerne une serrure à goupille avec au moins un boîtier de serrure, au moins un bras de tirage traversant le boîtier de serrure de manière déplaçable linéairement entre une position de verrouillage et une position de libération et au moins un dispositif de blocage pouvant être débloqué par un actionnement d’une clé, le bras de tirage étant précontraint dans le sens de sa position de verrouillage.Another recent invention relates to a tumbler lock with at least one lock housing, at least one pull arm passing through the lock housing in a linearly movable manner between a locking position and a releasing position and at least one blocking device which can be unlocked by actuation of a key, the pull arm being prestressed in the direction of its locking position.
Ce dernier dispositif présente l’inconvénient que la combinaison de hauteurs de goupille supérieure et de choix des puits dans lesquels sont insérées les goupilles permettant le blocage et la clef adaptée à cette combinaison sont fixés en usine. Ainsi, si l’utilisateur veut changer de clef et de combinaison, il lui faut changer de serrure. Le dispositif selon l’invention permet la même souplesse d’utilisation que les systèmes de barillet. Cette invention permet notamment la mise en place d’organigramme et de clef passe-partout tout en conservant les qualités des dispositifs de serrure avec blocage du bras de tirage par des goupilles. Divulgation de l'invention This latter device has the disadvantage that the combination of upper pin heights and choice of the wells in which the pins are inserted allowing the blocking and the key adapted to this combination are fixed in the factory. Thus, if the user wants to change the key and the combination, he must change the lock. The device according to the invention allows the same flexibility of use as barrel systems. This invention allows in particular the installation of a flowchart and a master key while retaining the qualities of lock devices with blocking of the pulling arm by pins. Disclosure of Invention

Un dispositif de verrouillage selon l’invention présente au moins une serrure à goupilles qui présente un boitier de serrure composé d’un couvercle, d’un bloc supérieur et d’un fond, un alésage dans le bloc supérieur ou dans le fond permet de guider et faire coulisser un bras de tirage, le fond du boitier permet de maintenir le bras de tirage contre le bloc supérieur. Le boitier de serrure est destiné à être fixé sur une porte et constitue la partie fixe de la serrure dans laquelle le bras de tirage peut glisser entre une position de verrouillage et une position de libération et au moins un dispositif de blocage pouvant être débloqué par un actionnement de la clé, qui présente au moins une goupille de blocage disposée de manière déplaçable linéairement transversalement à un sens de la translation du bras de tirage, goupille de blocage qui, dans une position de verrouillage, dans laquelle la goupille de blocage engage en partie un alésage sur le boîtier de serrure et en partie un alésage sur le bras de tirage disposé à fleur de l’alésage du boîtier de serrure avec le bras de tirage se trouvant en position de verrouillage, verrouille la translation linéaire du bras de tirage se trouvant en position de verrouillage et, dans une position de libération, dans laquelle la goupille de blocage est disposée entièrement à l’intérieur de l’alésage sur le bras de tirage, libère la translation linéaire du bras de tirage. A locking device according to the invention has at least one tumbler lock which has a lock box composed of a cover, an upper block and a bottom, a bore in the upper block or in the bottom makes it possible to guide and slide a pull arm, the bottom of the case keeps the pull arm against the upper block. The lock box is intended to be fixed on a door and constitutes the fixed part of the lock in which the pull arm can slide between a locking position and a release position and at least one locking device which can be unlocked by a actuation of the key, which has at least one locking pin arranged in a linearly movable manner transverse to a direction of translation of the pulling arm, locking pin which, in a locking position, in which the locking pin partially engages a bore on the lock case and partly a bore on the pull arm disposed flush with the bore of the lock case with the pull arm being in the locking position, locks the linear translation of the pull arm being in the locking position and, in a release position, in which the locking pin is disposed entirely within the bore on the d arm e draw, releases the linear translation of the draw arm.
La serrure à goupilles est constituée d’un boitier de serrure à goupilles traversé par un bras de tirage coulissant dans un alésage du boitier formant une glissière. Ce bras de tirage qui peut translater longitudinalement dans cette glissière est bloqué directement par un système de goupilles The tumbler lock consists of a tumbler lock box crossed by a sliding pull arm in a bore of the box forming a slide. This pulling arm which can translate longitudinally in this slide is blocked directly by a system of pins
Le bras de tirage se prolonge directement ou est fixé de manière débrayable ou non à un pêne qui vient s’engager dans la gâche. Le bras de tirage est actionnable de l’extérieur par le coté avant grâce à une tirette externe ou grâce à un fouillot débrayable ou non venant crocheter ce bras. The pull arm extends directly or is fixed in a disengageable manner or not to a bolt which engages in the striker. The pulling arm can be operated from the outside by the front side thanks to an external zipper or thanks to a disengageable follower or not coming to hook this arm.
Cette serrure a goupille est prévue pour être fixée en applique sur une porte ou en feuillure à l’intérieur de celle-ci par un système choisi par l’homme de l’art. This pin lock is intended to be fixed on the surface of a door or in a rebate inside the latter by a system chosen by those skilled in the art.
Par convention, nous appellerons la face avant de la serrure, la face dans laquelle on introduit la clef et du coté de laquelle l’utilisateur peut actionner le bras de tirage. Cette face avant correspond le plus souvent au côté extérieur d’une porte. La face arrière est la face opposée par laquelle l’utilisateur peut actionner directement le pêne si une telle option est choisie. Cette face arrière correspond le plus souvent au côté intérieur d’une porte. La face latérale est la face vers le pêne. La face médiale est la face vers les gonds de la porte. Il est convenu que le bras de tirage est horizontal. Bien évidemment, le système de serrure peut être installé dans toutes les positions adaptées à son usage. By convention, we will call the front face of the lock, the face in which the key is inserted and on the side of which the user can operate the pull arm. This front face most often corresponds to the exterior side of a door. The rear face is the opposite face by which the user can directly operate the bolt if such an option is chosen. This rear face most often corresponds to the interior side of a door. The side face is the face towards the bolt. The medial face is the face towards the hinges of the door. It is agreed that the pulling arm is horizontal. Of course, the lock system can be installed in any position suitable for its use.
Selon un premier mode de réalisation , chaque puits est formé d’un puits supérieur et d’un puits inférieur de telle sorte qu’en position fermée chaque puits contient au moins une goupille supérieure, une goupille inférieure et un ressort de goupille. Le puits supérieur est foré dans le bloc supérieur et est partiellement occlus dans sa partie supérieure par une saillie de blocage qui empêche la sortie des goupilles vers le haut et bloque la goupille supérieure dans une position maximale, tout en permettant le passage de la ou des saillies de la clef destinées à appuyer sur la ou les goupilles et de débloquer la serrure. Cette saillie de blocage peut provenir d’un usinage du bloc supérieur ou de tout autre moyen préféré par l’homme de l’art. Le puits inférieur est foré de part en part dans le bras de tirage en regard du puits supérieur quand la serrure est en position fermée. Un bouchon est inséré dans chaque puits inférieur par sa face inférieure et vient occlure ce puits inférieur dans sa partie inférieure. Ce bouchon est maintenu en place par vissage dans le puits inférieur ou introduit en force ou par tout moyen préféré par l’homme de l’art. Le ressort de goupille est placé en compression entre ce bouchon et la goupille inférieure. Le puits inférieur contient le bouchon, le ressort de goupille et au moins une goupille quand le bras de tirage est tiré dans une position d’ouverture. According to a first embodiment, each well is formed of an upper well and a lower well so that in the closed position each well contains at least one upper pin, one lower pin and one pin spring. The upper well is drilled in the upper block and is partially occluded in its upper part by a blocking protrusion which prevents the pins from coming out upwards and blocks the upper pin in a maximum position, while allowing the passage of the protrusions of the key intended to press on the pin or pins and to release the lock. This blocking protrusion can come from machining the upper block or from any other means preferred by those skilled in the art. The lower well is drilled right through in the pull arm facing the upper well when the lock is in the closed position. A plug is inserted into each lower well via its lower face and occludes this lower well in its lower part. This plug is held in place by screwing into the lower well or introduced by force or by any means preferred by those skilled in the art. The pin spring is placed in compression between this cap and the lower pin. The lower well contains the plug, the pin spring and at least one pin when the pull arm is pulled into an open position.
Selon une configuration avantageuse, un dispositif de blocage est composé d’un puits qui peut contenir de haut en bas une goupille supérieure, une goupille intermédiaire, une goupille inférieure, un ressort de goupille et un bouchon. Toutes les goupilles présentent les caractéristiques de taille et de résistance notamment qui permettent le bon fonctionnement d’une serrure à goupilles, comme il est bien connu par l’homme de l’art. Cette goupille intermédiaire permet l’utilisation de clef passe-partout et la création d’organigrammes avec des clefs maîtres dans un ensemble de serrures pour un bâtiment ou des coffres par exemple, à l’instar de ce qui est connu par l’homme de l’art avec les systèmes de barillet dans les serrures à barillet. According to an advantageous configuration, a locking device is composed of a well which can contain from top to bottom an upper pin, an intermediate pin, a lower pin, a pin spring and a plug. All the pins have the characteristics of size and resistance in particular which allow the correct operation of a pin lock, as is well known by those skilled in the art. This intermediate pin allows the use of master key and the creation of flow charts with master keys in a set of locks for a building or safes for example, like what is known by the man of the art with cylinder systems in cylinder locks.
Selon une autre configuration avantageuse, l’ensemble des puits supérieurs terminés dans leur partie supérieure par une saillie de blocage est contenu dans une partie amovible du bloc supérieur pour former une cassette supérieure. Chaque puits supérieur contient une goupille supérieure ou une goupille supérieure et une goupille intermédiaire quand le bras de tirage est tiré dans une position d’ouverture, cette ou ces goupilles étant maintenues dans ce puits supérieur par la saillie de blocage vers le haut et par la face supérieure du bras de tirage vers le bas. Cette cassette supérieure est introduite ou extraite de son logement dans le bloc supérieur par l’arrière afin d’en empêcher l’accession par l’avant. According to another advantageous configuration, the set of upper wells terminated in their upper part by a blocking projection is contained in a removable part of the upper block to form an upper cassette. Each upper well contains an upper pin or an upper pin and an intermediate pin when the pull arm is pulled into an open position, this or these pins being held in this upper well by the locking projection upwards and by the upper side of the draw arm down. This upper cassette is inserted or extracted from its housing in the upper block from the rear in order to prevent access from the front.
Selon une autre configuration avantageuse, l’ensemble des puits inférieurs est contenu dans une partie amovible du bras de tirage pour former une cassette de tirage. Quand le bras de tirage est tiré dans une position d’ouverture, chaque puits inférieur contient une goupille inférieure ou une goupille intermédiaire et une goupille inférieure, un bouchon et un ressort de goupille en compression entre la goupille inférieure et le bouchon. La ou les goupilles et le ressort sont maintenus dans ce puits par la face inférieure du bloc supérieur vers le haut et par le bouchon vers le bas. L’alésage complet du puits inférieur permet également d’introduire tous les éléments que chaque puits doit contenir pour un bon fonctionnement avant que le bouchon ne soit mis en place et solidement fixé dans la partie basse de chaque puits inférieur. Un passage est alésé vers l’arrière dans le boitier de la serrure afin de donner accès à la partie arrière de la cassette de tirage quand le bras de tirage est en position bloquée. Cette cassette de tirage est introduite ou extraite de son logement dans le bras de tirage par l’arrière afin d’en empêcher l’accession par l’avant. According to another advantageous configuration, all of the lower wells are contained in a removable part of the pulling arm to form a pulling cassette. When the pull arm is pulled into an open position, each bottom well contains a bottom pin or intermediate pin and bottom pin, a plug, and a pin spring in compression between the bottom pin and the plug. The pin or pins and the spring are held in this well by the underside of the upper block upwards and by the cap downwards. The complete reaming of the lower well also makes it possible to introduce all the elements that each well must contain for proper operation before the plug is put in place and firmly fixed in the lower part of each lower well. A passage is bored to the rear in the lock case to provide access to the rear part of the pull cassette when the pull arm is in the locked position. This pulling cassette is inserted or extracted from its housing in the pulling arm from the rear in order to prevent access from the front.
Selon une autre configuration avantageuse, et grâce à un usinage précis du bloc supérieur et de la cassette supérieure, la cassette supérieure est fixée au bloc supérieur de manière stable et rigide dans la position permettant un bon fonctionnement de la serrure tout en permettant le retrait de la cassette supérieure. Ceci peut être par exemple obtenu grâce à une ou plusieurs tenons de la cassette venant rentrer dans une ou plusieurs mortaises du bloc supérieur et à une ou plusieurs vis accessibles de l’arrière de la serrure venant fixer la cassette supérieure sur le bloc supérieur. According to another advantageous configuration, and thanks to precise machining of the upper block and of the upper cassette, the upper cassette is fixed to the upper block in a stable and rigid manner in the position allowing correct operation of the lock while allowing the removal of the upper cassette. This can be obtained, for example, by means of one or more tenons of the cassette coming into one or more mortises of the upper block and one or more screws accessible from the rear of the lock fixing the upper cassette to the upper block.
Selon une autre configuration avantageuse, et grâce à un usinage précis du bras de tirage et de la cassette de tirage, la cassette de tirage est fixée au bras de tirage de manière stable et rigide dans la position permettant un bon fonctionnement de la serrure tout en permettant le retrait de la cassette de tirage par le passage pratiqué dans le boitier de serrure. Ceci peut être par exemple obtenu grâce à une ou plusieurs tenons de la cassette venant rentrer dans une ou plusieurs mortaises du bras de tirage et à une ou plusieurs vis accessibles de l’arrière de la serrure venant fixer la cassette de tirage sur le bras de tirage. According to another advantageous configuration, and thanks to precise machining of the pull arm and of the pull cassette, the pull cassette is fixed to the pull arm in a stable and rigid manner in the position allowing proper operation of the lock while allowing the removal of the draw cassette through the passage made in the lock box. This can be obtained, for example, by means of one or more tenons of the cassette coming into one or more mortises of the pull arm and one or more screws accessible from the rear of the lock fixing the pull cassette on the pull arm. draw.
Selon une autre configuration avantageuse, un dispositif appelé kit de pose et composé d’une plaque de pose et de systèmes de fixation de cette plaque aux cassettes et se présentant au moins en partie sous la forme d’une plaque est usiné de telle sorte qu’il puisse se plaquer contre les faces internes des cassettes quand celles- ci sont en position de serrure bloquée à travers le passage du boitier, avec possibilité de solidariser solidement celles-ci sur cette plaque de pose tout en maintenant la position relative des cassettes entre elles de telle sorte que ce kit permet d’extraire en même temps la cassette supérieure de son logement dans le bloc supérieur et la cassette de tirage de son logement dans le bras de tirage tout en maintenant les puits inférieurs et les puits supérieurs alignés entre eux afin de maintenir ce qu’ils contiennent bloqué en bas par les bouchons et en haut par les saillies de blocage. La combinaison de hauteurs de goupilles et de disposition des puits étant spécifiques de la clef, il est ainsi possible de changer aisément les cassettes et les clefs à l’instar de ce qui se pratique dans les serrures à barillet. According to another advantageous configuration, a device called an installation kit and composed of an installation plate and systems for fixing this plate to the cassettes and appearing at least in part in the form of a plate is machined in such a way that it can be pressed against the internal faces of the cassettes when these are in the locked lock position through the passage of the box, with the possibility of firmly securing them to this mounting plate while maintaining the relative position of the cassettes between they are so that this kit makes it possible to extract the upper cassette from its housing in the upper block and the pulling cassette from its housing in the pulling arm at the same time while maintaining the lower wells and the upper wells aligned with each other in order to keep their contents blocked at the bottom by the plugs and at the top by the blocking protrusions. The combination of pin heights and arrangement of wells being specific to the key, it is thus possible to easily change the cassettes and the keys like what is practiced in cylinder locks.

Par convention, nous appellerons la face avant (35) de la serrure, la face par laquelle on introduit la clef (32) et du coté de laquelle l’utilisateur peut actionner le bras de tirage (9) par exemple en actionnant la tirette extérieure (4). Cette face avant (35) correspond le plus souvent au côté extérieur d’une porte. La face arrière (12) est la face opposée par laquelle l’utilisateur peut actionner directement le pêne (3) si une telle option est choisie, notamment et sans limitation par l’utilisation d’une tirette intérieure. Cette face arrière correspond le plus souvent au côté intérieur d’une porte. La face latérale (15) est la face vers le pêne (3). La face médiale (13) est la face vers les gonds de la porte. Il est convenu que le bras de tirage (9) est horizontal. Bien évidemment, le système de serrure peut être installé dans toutes les positions adaptées à son usage. By convention, we will call the front face (35) of the lock, the face through which the key (32) is introduced and on the side of which the user can actuate the pull arm (9) for example by actuating the external pull tab (4). This front face (35) most often corresponds to the exterior side of a door. The rear face (12) is the opposite face by which the user can directly activate the bolt (3) if a such option is chosen, in particular and without limitation by the use of an interior zipper. This rear face most often corresponds to the interior side of a door. The side face (15) is the face towards the bolt (3). The medial face (13) is the face towards the hinges of the door. It is agreed that the pulling arm (9) is horizontal. Of course, the lock system can be installed in any position suitable for its use.
La figure 1 illustre une vue de l’ensemble du dispositif selon l’invention en position fermée. Il est composé d’un bras de tirage (9) pouvant coulisser dans le boitier de serrure selon un sens de translation (42) médio-latéral. Le boitier de serrure est composé d’un couvercle (1), d’un bloc supérieur (5) et d’un fond (7) solidement fixés ensemble par exemple par quatre boulons et écrous ou des vis (non représentés ici) passant par des trous (2) traversant ces trois éléments ou par tout autre moyen préféré par l’homme de l’art. Le boitier de serrure forme la partie fixe du dispositif et est destiné à être fixé sur la porte qu’il est destiné à sécuriser par le moyen préféré par l’homme de l’art, par exemple en utilisant une équerre fixée d’une part aux vis de fixation du boitier et à la porte d’autre part. Figure 1 illustrates a view of the entire device according to the invention in the closed position. It is composed of a pulling arm (9) which can slide in the lock case in a direction of translation (42) medio-laterally. The lock box is composed of a cover (1), an upper block (5) and a bottom (7) firmly fixed together, for example by four bolts and nuts or screws (not shown here) passing through holes (2) passing through these three elements or by any other means preferred by those skilled in the art. The lock box forms the fixed part of the device and is intended to be fixed on the door which it is intended to secure by the means preferred by those skilled in the art, for example by using a bracket fixed on the one hand to the fixing screws of the case and to the door on the other hand.
Le bloc supérieur (5) est alésé pour former une gouttière dans laquelle vient s’ajuster le bras de tirage (9) afin de le guider précisément tout en permettant sa translation entre sa position bloquée, le pêne (3) étant engagé dans la gâche, et une position d’ouverture par traction de l’utilisateur de la tirette extérieur (4) ou d’une clenche ou poignée reliée à un fouillot par exemple. Cette gouttière pouvant être au choix de l’homme de l’art réalisée par alésage du fond (7) sans que cela ne change en rien les caractéristiques de l’invention. The upper block (5) is bored to form a gutter in which the pull arm (9) fits in order to guide it precisely while allowing its translation between its locked position, the bolt (3) being engaged in the striker. , and an open position by pulling the user of the outer zipper (4) or a latch or handle connected to a follower for example. This gutter can be chosen by those skilled in the art by boring the bottom (7) without this in any way changing the characteristics of the invention.
Le fond (7) est alésé pour venir plaquer le bras de tirage (9) contre la face inférieure du bloc supérieur (5) et participer à la gouttière dans laquelle ce bras de tirage (9) vient coulisser. Ce fond (7) peut être constitué d’une plaque avec une partie médiale (36) et une partie latérale (37) ou dans une autre configuration, il peut être préféré afin d’alléger le dispositif qu’il soit constitué uniquement d’une barre latérale (37) et d’une barre médiale (36) venant plaquer le bras de tirage (9) contre le bloc supérieur (5) sans recouvrir la partie inférieure centrale du bras de tirage (9). The bottom (7) is bored to press the pull arm (9) against the underside of the upper block (5) and participate in the gutter in which this pull arm (9) slides. This bottom (7) can consist of a plate with a medial part (36) and a lateral part (37) or in another configuration, it can be preferred in order to lighten the device that it consists only of a lateral bar (37) and a medial bar (36) pressing the pulling arm (9) against the upper block (5) without covering the lower central part of the pulling arm (9).
Un système élastique permettant au dispositif d’avoir une position de repos dans la position bloquée peut être par exemple réalisé grâce à un ressort principal (6) en traction entre la face médiale de la partie médiale du fond (36) et une partie médiale du bras de tirage (9), l’homme de l’art effectuant ces liaisons de la manière la plus judicieuse. An elastic system allowing the device to have a rest position in the locked position can be achieved, for example, by means of a main spring (6) in traction between the medial face of the medial part of the bottom (36) and a medial part of the pulling arm (9), the person skilled in the art making these connections in the most judicious manner.
Le bloc supérieur (5) est alésé sur sa partie arrière pour former un passage des cassettes (17) en regard des cassettes supérieure (11 ) et de tirage (8) quand celles-ci sont en position bloquée, afin de pouvoir les insérer ou les extraire de la serrure. Il peut être également nécessaire d’aléser par endroit la partie arrière inférieure du couvercle (1 ) en regard des saillies de blocage (29) si celles-ci ou d’autres parties de la cassette supérieure (11) dépassait vers le haut de la surface supérieure du bloc supérieur (5), afin de permettre l’extraction ou l’insertion des cassettes supérieures (11) par ce passage (17) The upper block (5) is bored on its rear part to form a passage for the cassettes (17) facing the upper cassettes (11) and draw cassettes (8) when the latter are in the locked position, in order to be able to insert them or extract them from the lock. It may also be necessary to bore in places the lower rear part of the cover (1) opposite the locking projections (29) if these or other parts of the upper cassette (11) protrude upwards from the upper surface of the upper block (5), in order to allow the extraction or insertion of the upper cassettes (11) through this passage (17)
Sur cette vue en perspective arrière, on peut apercevoir par le passage des cassettes (17) la cassette supérieure (11 ) fixée au bloc supérieure (5) par deux vis (18) et la cassette de tirage (8) fixée au bras de tirage (9) par deux vis (10). On this rear perspective view, one can see through the passage of the cassettes (17) the upper cassette (11) fixed to the upper block (5) by two screws (18) and the draw cassette (8) fixed to the draw arm (9) by two screws (10).
La Figure 2 montre une représentation schématique en coupe verticale longitudinale latéro-médiale passant par l’axe d’un puits, la serrure étant en position bloquée et fermée. Figure 2 shows a schematic representation in latero-medial longitudinal vertical section passing through the axis of a shaft, the lock being in the blocked and closed position.
La serrure comprend au moins un dispositif de blocage (41) et il en est représenté six sur les schémas de cet exemple de réalisation. Chaque dispositif de blocage (41 ) est constitué d’un puits formé par la superposition d’un puits supérieur (30) sur un puits inférieur (21), les deux puits étant faiblement discontinus, le puits supérieur (30) étant partiellement occlus dans son extrémité supérieure par la saillie de blocage (29), le puits inférieur (21 ) étant occlus par un bouchon (19) introduit dans la partie basse du puits inférieur (21 ). Chaque dispositif de blocage (41) comprend au moins une goupille de blocage supérieure (25), une goupille inférieure (24), éventuellement une goupille intermédiaire intercalée entre les deux précédentes goupilles (25, 24) et un ressort de goupille (20) placé en compression entre la face supérieure du bouchon (19) et la face inférieure de la goupille inférieure (24). La goupille inférieure (24) peut être alésée dans sa partie inférieure pour mieux maintenir le ressort de goupille (20). The lock comprises at least one blocking device (41) and six of these are shown in the diagrams of this example embodiment. Each blocking device (41) consists of a well formed by the superposition of an upper well (30) on a lower well (21), the two wells being slightly discontinuous, the upper well (30) being partially occluded in its upper end by the blocking projection (29), the lower well (21) being occluded by a plug (19) introduced into the lower part of the lower well (21). Each locking device (41) comprises at least one upper locking pin (25), a lower pin (24), possibly an intermediate pin inserted between the two previous pins (25, 24) and a pin spring (20) placed in compression between the upper face of the plug (19) and the lower face of the lower pin (24). The lower pin (24) can be bored in its lower part to better hold the pin spring (20).
Le couvercle est alésé pour former le logement de clef (28) dans lequel viendra s’insérer la clef (32) non représentée ici. Le couvercle (1) est fixé sur le bloc supérieur (5). La cassette supérieure (11 ) est en position dans le bloc supérieur (5) et engagée dans le logement (39) alésé dans le bloc supérieur (5) avec les tenons de la cassette supérieure (27) insérés dans les mortaises (28) du bloc supérieur (5), la cassette supérieure (27) fixée grâce à des vis de fixation (18) dans le bloc supérieur. Sa face inférieure est positionnée en continuité avec la face inférieure du bloc supérieur (5). Sa hauteur comprenant la saillie de blocage (29) est telle que la goupille supérieure (25) dans sa position la plus haute corresponde à la position la plus haute souhaitée de la surface d’actionnement de la dent de la clef (32), et en tout état de cause que la goupille supérieure (25) puisse être insérée sous le plafond du logement de clef (28) et que la clef (32) puisse rentrer dans son logement (28) et repousser vers le bas cette goupille supérieure (25). The lid is bored to form the key housing (28) into which the key (32) not shown here will be inserted. The cover (1) is fixed on the upper block (5). The upper cassette (11) is in position in the upper block (5) and engaged in the housing (39) bored in the upper block (5) with the tenons of the upper cassette (27) inserted in the mortises (28) of the upper block (5), the upper cassette (27) fixed by fixing screws (18) in the upper block. Its lower face is positioned in continuity with the lower face of the upper block (5). Its height including the locking projection (29) is such that the upper pin (25) in its highest position corresponds to the desired highest position of the key tooth actuating surface (32), and in any event that the upper pin (25) can be inserted under the ceiling of the key housing (28) and that the key (32) can enter its housing (28) and push down this upper pin (25 ).
Dans la cassette supérieure (11 ), au moins un puits supérieur (30) contient une goupille supérieure (25) en appui contre la saillie de blocage (29) usinée dans la cassette supérieure (27). La saillie de blocage (29) est usinée de telle sorte qu’elle bloque la sortie de la goupille supérieure (25) vers le haut tout en permettant le passage du ou des éléments de la clef (32) destinés à venir enfoncer la ou les goupilles supérieures (25) pour débloquer la serrure. Ceci peut être réalisé par exemple et sans limitation par la création d’un profilé qui forme une rainure laissant un passage à la ou aux saillies d’actionnement de la clef (32), ce passage étant trop étroit pour laisser sortir la ou les goupilles supérieures (25). La serrure étant en position bloquée, la goupille inférieure (24), poussée vers le haut contre la goupille supérieure (25) par le ressort de goupille (20), est en partie engagée dans le puits supérieur (30) et dans le puits inférieur (21 ) et bloque toute translation (42) du bras de tirage (9) par rapport au bloc supérieur (5). In the upper cassette (11), at least one upper well (30) contains an upper pin (25) resting against the locking projection (29) machined in the upper cassette (27). The blocking projection (29) is machined in such a way that it blocks the output of the upper pin (25) upwards while allowing the passage of the element or elements of the key (32) intended to drive the upper pins (25) to unlock the lock. This can be achieved for example and without limitation by the creation of a profile which forms a groove leaving a passage for the actuation projection(s) of the key (32), this passage being too narrow to allow the pin(s) to come out. higher (25). With the lock in the locked position, the lower pin (24), pushed up against the upper pin (25) by the pin spring (20), is partially engaged in the upper well (30) and in the lower well (21) and blocks any translation (42) of the pulling arm (9) relative to the upper block (5).
Dans une autre configuration, une goupille intermédiaire (non représentée) peut être intercalée entre les deux goupilles (25, 24) et autorise ainsi deux positions permettant le déblocage de la serrure et l’usage de clef passe-partout ou de systèmes par organigramme avec des clefs maîtres par exemple. La réalisation de telles combinaisons est bien connue de l’homme de l’art. In another configuration, an intermediate pin (not shown) can be interposed between the two pins (25, 24) and thus authorizes two positions allowing the unlocking of the lock and the use of a master key or systems by flowchart with master keys for example. The making of such combinations is well known to those skilled in the art.
Le bras de tirage (9) peut être usiné par exemple et sans limitation de telle sorte que sa partie centrale soit plus épaisse et que son bord latéral vienne buter contre le bord médial de la partie latérale du fond (37) quand la serrure est en position bloquée et fermée et que son bord médial vienne buter contre le bord latéral de la partie médiale du fond (36) quand la serrure est débloquée et en position ouverte maximale. L’homme de l’art peut préférer une autre forme de limitation des translations (42) du bras de tirage (9) dans le boitier de serrure comme par exemple et sans limitation des saillies localisées, des encoches ou autres déformations. The pull arm (9) can be machined, for example and without limitation, so that its central part is thicker and its lateral edge comes to abut against the medial edge of the lateral part of the bottom (37) when the lock is in blocked and closed position and that its medial edge abuts against the lateral edge of the medial part bottom (36) when the lock is unlocked and in the maximum open position. Those skilled in the art may prefer another form of limitation of the translations (42) of the pull arm (9) in the lock case, such as, for example, and without limitation, localized projections, notches or other deformations.
La cassette de tirage (8) est en position dans le logement (40) alésé dans la barre de tirage (9) avec les tenons de la cassette de tirage (22) insérés dans les mortaises du bras de tirage (23) usinés de telle sorte que la face supérieure de la cassette de tirage (22) soit très proche de la face inférieure de la cassette supérieure (11 ) et en continuité avec la face supérieure du bras de tirage (9), les puits supérieurs (30) et inférieurs (21 ) formant alors des puits faiblement discontinus et permettant la translation des goupilles de l’un à l’autre. Les vis de fixation (10) de la cassette de tirage (22) permettent de fixer celle-ci sur le bras de tirage (9). The pulling cassette (8) is in position in the housing (40) bored in the pulling bar (9) with the tenons of the pulling cassette (22) inserted in the mortises of the pulling arm (23) machined in such a way so that the upper face of the pulling cassette (22) is very close to the lower face of the upper cassette (11) and in continuity with the upper face of the pulling arm (9), the upper (30) and lower wells (21) then forming slightly discontinuous wells and allowing the translation of the pins from one to the other. The fixing screws (10) of the pulling cassette (22) make it possible to fix the latter on the pulling arm (9).
La cassette de tirage (8) contient au moins un puits inférieur (21 ) dans lequel une goupille inférieure (24) est poussée vers le haut par le ressort de goupille (20), lui- même posé sur la face supérieure du bouchon (19) inséré dans la partie basse du puits inférieur (21 ) et étant fixé par tout moyen conseillé par l’homme de l’art par exemple en force ou vissé dans le puits inférieur (21). La goupille inférieure (24) poussé par le ressort de goupille (20) est engagée dans le puits supérieur (30) et empêche la translation (42) du bras de tirage (9) par rapport au bloc supérieur (5).The draw cassette (8) contains at least one lower well (21) in which a lower pin (24) is pushed upwards by the pin spring (20), itself placed on the upper face of the stopper (19 ) inserted into the lower part of the lower well (21) and being fixed by any means recommended by those skilled in the art, for example by force or screwed into the lower well (21). The lower pin (24) pushed by the pin spring (20) is engaged in the upper well (30) and prevents the translation (42) of the draw arm (9) relative to the upper block (5).
Les goupilles (24, 25), l’éventuelle goupille intermédiaire et le ressort de goupille (20) sont introduits en usine par la face inférieure de la cassette de tirage (8), celle-ci étant solidarisée avec la cassette supérieure (11 ) afin que les puits (21 , 30) forment un puits faiblement discontinu, la saillie de blocage (24) empêchant la sortie de ces éléments par le haut du puits supérieur (30). Le puits inférieur (21) est alors occlus par le bouchon (19). The pins (24, 25), any intermediate pin and the pin spring (20) are introduced in the factory through the underside of the draw cassette (8), the latter being secured to the upper cassette (11) so that the wells (21, 30) form a slightly discontinuous well, the blocking projection (24) preventing the exit of these elements from the top of the upper well (30). The lower well (21) is then occluded by the plug (19).
La Figure 3 représente une coupe verticale transversale passant par plusieurs axes de goupilles (24, 25), la clef (32) étant dans son logement (28), la serrure étant débloquée et fermée. Figure 3 shows a transverse vertical section passing through several axes of pins (24, 25), the key (32) being in its housing (28), the lock being unlocked and closed.
Le couvercle (1) est alésé pour former le logement de clef (28) de telle sorte que la clef (32) se place naturellement quand elle est poussée à fond contre le fond de son logement (28) dans la position permettant de débloquer la serrure. Une autre configuration intéressante de la clef (32) peut être par exemple un usinage de celle-ci réalisé de telle sorte qu’une saillie de la clef (32) vienne buter contre la face avant du logement (28) de clef et limite l’enfoncement de celle-ci. The cover (1) is bored to form the key housing (28) so that the key (32) fits naturally when it is pushed fully against the bottom of its housing (28) in the position allowing the unlocking of the lock. Another interesting configuration of the key (32) can for example be a machining thereof made in such a way that a projection of the key (32) abuts against the front face of the housing (28) of the key and limits the penetration of the latter.
Les dents ou alésages de la clef (32), par leur surface d’actionnement, permettent de pousser les goupilles supérieures (25) de telle sorte que leur partie inférieure affleure la face inférieure de la cassette supérieure (11 ). Les goupilles inférieures (24) sont repoussées dans leur puits inférieur (21 ) et leur face supérieure affleure la face supérieure de la cassette de tirage (8). Le bras de tirage (9) peut ainsi être libéré et translater (42) vers une position d’ouverture. The teeth or bores of the key (32), by their actuating surface, make it possible to push the upper pins (25) so that their lower part is flush with the underside of the upper cassette (11). The lower pins (24) are pushed back into their lower well (21) and their upper face is flush with the upper face of the draw cassette (8). The pulling arm (9) can thus be released and translate (42) towards an open position.
On peut voir sur cette coupe une configuration intéressante concernant les dimensions des cassettes (11 , 8) et de leur logement (39, 40) qui peuvent avoir la même longueur antéro-postérieure. La cassette supérieure (11 ) doit avoir une longueur inférieure à la largeur du bloc supérieur (5) afin que celle-ci ne soit pas accessible de l’avant (35) pour obtenir une bonne solidité du boitier de la serrure et empêcher une effraction en atteignant la cassette supérieure (11). De même, la cassette de tirage (8) doit avoir une longueur inférieure à la largeur du bras de tirage (9) à l’endroit où la cassette de tirage (8) est fixée afin de conserver une continuité du bras de tirage (9) et donc une solidité du bras de tirage (9). One can see on this section an interesting configuration concerning the dimensions of the cassettes (11, 8) and their housing (39, 40) which can have the same antero-posterior length. The upper cassette (11) must have a length less than the width of the upper block (5) so that it is not accessible from the front (35) to obtain good solidity of the lock case and prevent break-in when reaching the upper cassette (11). Similarly, the pulling cassette (8) must have a length less than the width of the pulling arm (9) at the place where the pulling cassette (8) is fixed in order to maintain continuity of the pulling arm (9 ) and therefore a strength of the pulling arm (9).
Le passage des cassettes (17) est alésé dans la partie verticale arrière du bloc supérieure (5) afin de permettre l’accès aux cassettes (11 , 8) par l’arrière (12). Cet alésage peut être légèrement prolongé vers le haut (14) dans la partie arrière (12) du couvercle (1) afin de permettre le passage de la cassette supérieure (11 ). The passage for the cassettes (17) is bored in the rear vertical part of the upper block (5) in order to allow access to the cassettes (11, 8) from the rear (12). This bore can be extended slightly upwards (14) in the rear part (12) of the cover (1) in order to allow the passage of the upper cassette (11).
La Figure 4 montre une vue en perspective par l’arrière de la serrure en position ouverte. Figure 4 shows a rear perspective view of the lock in the open position.
Le bras de tirage (9) a été tiré médialement (42) par une traction sur la tirette externe (4) et le ressort principal (6) est étiré. The draw arm (9) has been pulled medially (42) by pulling on the outer pull rod (4) and the main spring (6) is stretched.
On peut apercevoir par le passage des cassettes (17) le bras de tirage (9) et la cassette de tirage (8) tirés médialement (42) ainsi que le pêne (3) en partie rentré dans le boitier de serrure. One can see through the passage of the cassettes (17) the pull arm (9) and the pull cassette (8) pulled medially (42) as well as the bolt (3) partially retracted into the lock case.
La clef (32) dont une partie est visible a été introduite dans son logement (28) et a permis le déblocage de la serrure. La Figure 5 montre un gros plan en perspective arrière du kit interchangeable (31 ) qui est composé du kit de pose (38) composé lui-même de la plaque de pose (33), des vis du kit de pose (34), de la cassette supérieure (11 ), de la cassette de tirage (8) et de la clef (32) correspondant à la combinaison de goupilles et de puits contenus dans les cassettes (11 , 8) et formant les dispositifs de blocage (41 ). La fixation de la plaque de pose (33) aux cassettes (11 , 8) en position bloquée de la cassette supérieure (11 ) sur la cassette de tirage (8) permet de maintenir le ou les puits supérieurs (30) parfaitement alignés avec le ou les puits inférieurs (21 ) qui leur correspondent. Ainsi, même sorties de la serrure, les goupilles (24, 25) et les ressorts de goupille (20) restent enfermés dans les puits. Ces éléments sont maintenus en haut par les saillies de blocage (29) et en bas par les bouchons (19). Les tenons (22, 27) des cassettes (11 , 8) sont visibles et permettront un parfait positionnement des cassettes (11 , 8) dans leur logement (39, 40) respectif de la serrure. The key (32), part of which is visible, has been introduced into its housing (28) and has enabled the unlocking of the lock. Figure 5 shows a close-up in rear perspective of the interchangeable kit (31) which is composed of the installation kit (38) itself composed of the installation plate (33), installation kit screws (34), the upper cassette (11), the draw cassette (8) and the key (32) corresponding to the combination of pins and wells contained in the cassettes (11, 8) and forming the locking devices (41). The fixing of the laying plate (33) to the cassettes (11, 8) in the locked position of the upper cassette (11) on the draw cassette (8) makes it possible to maintain the upper well or wells (30) perfectly aligned with the or the lower wells (21) which correspond to them. Thus, even out of the lock, the pins (24, 25) and the pin springs (20) remain locked in the wells. These elements are held at the top by the locking projections (29) and at the bottom by the plugs (19). The tenons (22, 27) of the cassettes (11, 8) are visible and will allow a perfect positioning of the cassettes (11, 8) in their respective housing (39, 40) of the lock.
Il a été dessiné ici pour exemple une combinaison de 6 dispositifs de blocage (41 ) alignés contenant chacun un puits supérieur (30), un puits inférieur (21) une goupille supérieure (25), une goupille inférieure (26), un ressort de goupille (20) et un bouchon (19). Sans rien changer au principe du dispositif selon l’invention, il aurait été possible de choisir d’autres combinaisons, par exemple des dispositifs de blocage (41) non alignés ou alignés sur plusieurs lignes et l’ajout dans certains puits (30, 21) ou dans tous d’une goupille intermédiaire permettant l’utilisation de clef (32) passe partout et la mise en place d’organigrammes dans des installations complexes avec plusieurs niveaux d’autorisations pour les utilisateurs. It has been drawn here for example a combination of 6 locking devices (41) aligned each containing an upper well (30), a lower well (21) an upper pin (25), a lower pin (26), a spring pin (20) and a cap (19). Without changing anything to the principle of the device according to the invention, it would have been possible to choose other combinations, for example blocking devices (41) not aligned or aligned on several lines and the addition in certain wells (30, 21 ) or in all of an intermediate pin allowing the use of key (32) passes everywhere and the establishment of flowcharts in complex installations with several levels of authorizations for the users.
La Figure 6 montre une vue en perspective par l’arrière de l’ensemble du dispositif selon l’invention sans la clef (32) et le couvercle supérieur (1) retiré. La cassette supérieure (11) et la cassette de tirage (8) sont fixées à la plaque de pose (33) au moyen de quatre vis (34), l’ensemble étant hors de la serrure. Figure 6 shows a perspective view from behind of the entire device according to the invention without the key (32) and the top cover (1) removed. The upper cassette (11) and the draw cassette (8) are fixed to the mounting plate (33) by means of four screws (34), the assembly being outside the lock.
On peut distinguer le logement (39) de la cassette supérieure (11) alésé dans le bloc supérieur (5) ainsi que le passage des cassettes (17) alésé dans la partie verticale arrière du bloc supérieur (5). Le logement (40) de la cassette de tirage (8) est alésé dans le bras de tirage (9), une partie de ce bras étant visible à travers le passage des cassettes (17). Les tenons (22, 27) des cassettes (11 , 8) sont prévus pour aller glisser dans les mortaises (23, 26) et les trous des vis (10,18) permettant de fixer les cassettes (11 , 8) sont visibles sur la partie arrière du bloc supérieur (5) et du bras de tirage (9). One can distinguish the housing (39) of the upper cassette (11) bored in the upper block (5) as well as the passage of the cassettes (17) bored in the rear vertical part of the upper block (5). The housing (40) of the pulling cassette (8) is bored in the pulling arm (9), part of this arm being visible through the passage of the cassettes (17). The tenons (22, 27) of the cassettes (11, 8) are designed to slide in the mortises (23, 26) and the screw holes (10,18) allowing the cassettes (11, 8) to be fixed are visible on the rear part of the upper block (5) and the pulling arm (9).
Le dispositif selon l’invention est particulièrement destiné à équiper les portes. The device according to the invention is particularly intended to equip doors.
