Description
La présente invention concerne une serrure à gorges coulissantes du type comprenant un boítier ou coffre comportant au moins une entrée de clé pour une clé à deux pannetons munis d'un crantage, au moins un pêne dormant solidaire d'une plaque de pêne montée à coulissement dans ledit boítier orthogonalement à la direction d'introduction de la clé dans le boítier, ladite plaque de pêne comportant une ouverture de passage de la clé dont un bord est muni de dents agencées pour engrener avec un panneton de la clé au cours de la rotation de la clé, une pluralité de gorges montées à coulissement dans ledit boítier orthogonalement à la direction de déplacement de ladite plaque de pêne et orthogonalement à la direction d'introduction de la clé, chacune des gorges étant soumise à l'action d'un ressort de rappel et comportant un bord profilé coopérant avec une denture du bord libre d'un panneton de la clé ainsi qu'une fenêtre profilée avec laquelle coopère un mentonnet solidaire de la plaque de pêne, l'ensemble étant agencé de telle manière que, après introduction de la clé, la rotation de cette clé produise l'alignement des fenêtres profilées des gorges, puis la translation de la plaque de pêne permise par le passage du mentonnet dans des rainures devenues alignées des fenêtres profilées des gorges, la poursuite de la rotation de la clé libérant les gorges qui, sous l'action de leurs ressorts de rappel, viennent dans une position de repos dans laquelle le mentonnet est verrouillé dans des encoches transversales aux rainures alignées, des fenêtres profilées des gorges.The present invention relates to a grooved lock sliding doors of the type comprising a box or trunk with at least one key entry for a two-person key bits fitted with a notch, at least one deadbolt secured to a bolt plate slidably mounted in said housing orthogonally to the direction of introduction of the key in the housing, said bolt plate comprising an opening for the passage of the key, one edge of which is provided with teeth arranged to mesh with a key bit during the rotation of the key, a plurality of grooves sliding mounted in said housing orthogonally to the direction of movement of said bolt plate and orthogonally to the direction of insertion of the key, each of the grooves being subjected to the action of a spring of return and comprising a profiled edge cooperating with a toothing of the free edge of a key bit as well as a profiled window with which an integral chin cooperates of the bolt plate, the assembly being arranged in such a way so that, after inserting the key, the rotation of this key produces the alignment of the profiled windows of the grooves, then the translation of the bolt plate allowed by the passage of the chin in grooves that have become aligned profiled windows of the gorges, the pursuit of rotation of the key releasing the grooves which, under the action of their return springs come in a rest position in which the chin is locked in notches transverse to aligned grooves, profiled windows gorges.
Cette serrure, connue par exemple par FR-A-2 596 796, offre une sécurité très élevée et a reçu un accueil commercial très favorable.This lock, known for example from FR-A-2,596,796, offers very high security and received a very commercial reception favorable.
Un inconvénient de ces serrures connues, comme de pratiquement toutes les serrures disponibles sur le marché, est que sa combinaison, déterminée par les dents de la clé et l'empilement correspondant de gorges, est fixe. Il en résulte que, en cas de changement de l'occupant d'un local, par exemple un appartement, équipé d'une telle serrure, le nouvel occupant peut craindre que l'ancien occupant ait conservé une clé et puisse ainsi avoir accès au local qu'il a quitté. Il en résulte que, pour éliminer ce risque, le nouvel occupant est obligé de changer toute la serrure alors que, avec des serrures à cylindre, un échange du cylindre, est suffisant, le mécanisme de serrure restant en place.A disadvantage of these known locks, such as practically all the locks available on the market, is that its combination, determined by the teeth of the key and the corresponding stack of grooves is fixed. The result that, in the event of a change of occupant of a room, by example an apartment, equipped with such a lock, the new occupant may fear that the former occupant may have retained key and thus have access to the room he left. he as a result, to eliminate this risk, the new occupant is forced to change the whole lock while with cylinder locks, an exchange of the cylinder is sufficient, the lock mechanism remaining in place.
Il est connu, par exemple par DE-B-1 156 674, de munir une serrure de deux systèmes de gorges, grâce auxquels on peut procéder à une modification de la combinaison par action de deux clés différentes.It is known, for example from DE-B-1 156 674, to provide a lock of two groove systems, thanks to which we can modify the combination by action of two different keys.
On a proposé, dans EP-A-0 656 454, d'utiliser ce même principe pour modifier la combinaison d'une serrure du type cité à l'introduction, à l'aide d'une clé spéciale.It has been proposed in EP-A-0 656 454 to use this same principle for modifying the combination of a lock of the type cited in the introduction, using a special key.
Les serrures à modification de combinaison connues selon les deux documents précédents présentent l'inconvénient de nécessiter l'utilisation d'une clé pour modifier la combinaison.Combination modification locks known according to two previous documents have the disadvantage of require the use of a key to change the combination.
La présente invention vise en conséquence à fournir une serrure du type décrit à l'introduction, dans laquelle chacune des gorges est constituée d'une gorge principale portant le bord profilé coopérant avec la denture de la clé et d'une gorge secondaire portant ladite fenêtre profilée avec laquelle coopère le mentonnet de la plaque de pêne, les gorges principales et secondaires étant solidaires en translation par des moyens permettant un désaccouplement libérant les gorges principales et verrouillant les gorges secondaires en position désaccouplée, dans laquelle le changement de combinaison peut être effectué sans clé spéciale.The present invention therefore aims to provide a lock of the type described in the introduction, in which each of the gorges is made up of a main groove bearing the profiled edge cooperating with the teeth of the key and a secondary groove carrying said profiled window with which cooperates the chin of the latch plate, the main and secondary gorges being integral in translation by means allowing uncoupling releasing the main grooves and locking the grooves in the uncoupled position, in which the change of combination can be done without a key special.
A cet effet, la serrure selon l'invention est caractérisée par le fait qu'un chariot solidaire en translation des gorges secondaires est monté mobile en translation dans le coffre de serrure, orthogonalement à la direction de déplacement des gorges, sous l'action d'au moins un organe de commande accessible par la paroi frontale du coffre à travers laquelle fait saillie le pêne.To this end, the lock according to the invention is characterized by the fact that a carriage secured in translation of the grooves secondary is mounted movable in translation in the trunk of lock, orthogonal to the direction of movement of the grooves, under the action of at least one control member accessible by the front wall of the trunk through which protrudes the bolt.
Selon une forme de réalisation de l'invention, ledit organe de commande est constitué par une vis dont la tête est fixe en translation et dont la tige est en prise dans un taraudage du chariot.According to one embodiment of the invention, said member control consists of a screw whose head is fixed in translation and whose rod is engaged in a thread of the carriage.
Selon une variante de l'invention, ledit organe de commande comprend un axe rotatif dont la tête est accessible depuis l'extérieur du coffre, ledit axe étant muni d'au moins une dent profilée coopérant avec une rampe d'une pièce solidaire du chariot de manière à provoquer, par une rotation déterminée dudit axe rotatif, une translation correspondante dudit chariot. De préférence, ledit axe porte une pointe de centrage et de butée coopérant avec un évidemment correspondant de ladite pièce.According to a variant of the invention, said control member includes a rotary axis whose head is accessible from the exterior of the trunk, said axis being provided with at least one profiled tooth cooperating with a ramp of an integral part of the carriage so as to cause, by rotation determined from said rotary axis, a corresponding translation of said carriage. Preferably, said axis carries a point of centering and stop cooperating with an obviously correspondent of said room.
Avantageusement, les gorges principales et secondaires sont accouplées par l'intermédiaire de dentures en prise réciproque et les gorges secondaires sont montées mobiles en translation orthogonale à la direction de déplacement des gorges principales sous l'action d'un organe de désaccouplement et comportent chacune une encoche de verrouillage coopérant en position de désaccouplement avec un téton fixe.Advantageously, the main and secondary gorges are mated by engaging teeth reciprocal and the secondary grooves are mounted movable in translation orthogonal to the direction of movement of main gorges under the action of a body of uncoupling and each have a notch of interlocking cooperating in uncoupling position with a fixed nipple.
De préférence, les gorges secondaires comportent des fentes de guidage, parallèles à la direction de déplacement des gorges, dans lesquelles sont logés des piliers en saillie dudit chariot.Preferably, the secondary grooves have slots guide, parallel to the direction of movement of the grooves, in which protruding pillars are housed of said carriage.
L'invention sera bien comprise à la lecture de la description
suivante d'exemples de réalisation, en référence au dessin
annexé dans lequel :
On se réfère tout d'abord aux figures 1 à 3.We first refer to Figures 1 to 3.
La serrure comprend un boítier creux 1 ou coffre constitué
d'une plaque de fond 2, constituant la face externe de la
serrure, entourée d'une couronne 3 comportant une paroi
frontale plane 4. La paroi frontale 4 comporte quatre
orifices de passage de pênes dormants 5 solidaires d'une
plaque 6 commune. La plaque 6 et les pênes 5 sont mobiles en
translation dans la direction X-X de la figure 1.The lock comprises a
Une pluralité de gorges 7 sont montées superposées dans le
boítier 1 et peuvent coulisser indépendamment les unes des
autres, dans la direction Y-Y orthogonale à la direction X-X.
Les gorges 7, qui sont soumises chacune à l'action d'un
ressort de rappel (non représenté), possèdent chacune un bord
profilé 8 destiné à coopérer avec la denture d'une clé (non
représentée) introduite par une fente 9 ménagée dans le fond
2 du coffre 1. La position longitudinale du bord profilé 8
sur chaque gorge 7 détermine la combinaison de la serrure.A plurality of
L'introduction de la clé dans le coffre à travers la fente 9
se fait donc perpendiculairement au plan du dessin, c'est-à-dire
orthogonalement aux directions X-X et Y-Y et sa rotation
entraíne une translation indépendante de chacune des gorges 7
dont l'amplitude est déterminée, pour chaque gorge, par la
portion de denture de clé qui lui fait face.The introduction of the key into the trunk through the
Au cours de cette translation, les gorges 7 sont guidées par
deux piliers fixes 10 coopérant avec des fentes opposées 11
des gorges.During this translation, the
La plaque 6 des pênes 5 porte une denture 12 avec laquelle
peut alors engrener un panneton de clé pour produire une
translation de la plaque 6, et des pênes 5, dans la direction
de verrouillage (ou de déverrouillage lorsque la serrure est
verrouillée). Cette translation n'est possible que si toutes
les gorges 7 ont subi une translation correspondant à la
combinaison de la serrure. La plaque 6 porte en outre une
fenêtre profilée 6' avec laquelle coopère un téton (non
représenté) de la face adjacente de la gorge 7 la plus proche
pour assurer un verrouillage de la plaque 6.The
Une fenêtre profilée 13 est portée par chaque gorge et, dans
le cas de la présente invention, dans une portion 7' de
chaque gorge 7, dite secondaire par opposition à la gorge 7
dite principale, associée. La fenêtre profilée 13 est
constituée par une rainure centrale 14 parallèle à la
direction X-X et des encoches latérales 15. Dans les fenêtres
13 des différentes gorges est logé un mentonnet 16 solidaire
de la plaque 6 portant les pênes 5. Lorsque le mentonnet 16
est logé dans une encoche 15 d'une fenêtre 13, la plaque 6
et, donc, les pênes 5 sont verrouillés en position de
déverrouillage (sur le dessin) ou en position de
verrouillage. Ce n'est que lorsque les rainures 14 des
fenêtres 13 de toutes les gorges sont alignées à hauteur du
mentonnet 16 que la plaque 6 et les pênes 5 peuvent être
déplacés en translation par l'engrènement du panneton de la
clé avec la denture 12, comme décrit précédemment.A profiled window 13 is carried by each groove and, in
the case of the present invention, in a 7 'portion of
each
Conformément à l'invention, la partie 7' de la gorge
principale 7, ou gorge secondaire 7', est une pièce
indépendante, les gorges principales 7 et secondaires 7'
étant normalement solidaires en translation selon la
direction Y-Y par des dentures complémentaires. Les gorges
secondaires 7' sont rendues solidaires, en translation selon
la direction X-X, d'un support ou chariot 17. A cet effet, le
chariot 17 porte deux piliers 18 coopérant chacun avec une
fente de guidage 19 de chaque gorge secondaire 7', lesdites
fentes 19 s'étendant selon la direction Y-Y, de manière à ne
pas gêner la translation des gorges 7, 7' lorsqu'elles sont
solidaires (figures 1 et 2) par l'intermédiaire des dentures
complémentaires. Dans ce cas, la serrure fonctionne
normalement comme si les gorges principales 7 et secondaires
7' formaient des gorges uniques.According to the invention, the part 7 'of the groove
main 7, or secondary groove 7 ', is a part
independent, the main 7 and secondary 7 'gorges
normally being united in translation according to the
direction Y-Y by complementary teeth. The throats
secondary 7 'are made integral, in translation according to
the direction X-X, of a support or
Le chariot 17 est monté mobile en translation dans la
direction X-X sous l'action de vis 20 dont la tête 21, fixe
en translation, est accessible par la paroi frontale 4 du
coffre 1, de sorte que cette tête 21 est inaccessible lorsque
la porte sur laquelle est montée la serrure est fermée, cette
paroi frontale 4 étant en regard d'une gâche (non
représentée). La vis 20 est en prise dans un taraudage de la
plaque 6.The
Une action sur les vis 20, 21 permet d'écarter l'ensemble des
gorges secondaires 7' (figure 3) lorsque la clé correspondant
à la combinaison a été introduite et tournée de 90°. Cette
translation s'effectue alors par l'intermédiaire des piliers
18 agissant orthogonalement sur les rainures 19. Les gorges
secondaires 7' sont alors verrouillées par coopération d'une
encoche de verrouillage 22 qu'elles présentent avec un téton
fixe 23 solidaire du coffre 1.An action on the
Après avoir ramené la clé en position de repos et l'avoir
extraite, il suffit d'insérer une nouvelle clé à une
combinaison différente, et de la faire tourner de 90°. Les
gorges principales 7, libres en translation, sont amenées à
la position correspondant à la nouvelle combinaison par la
denture de la nouvelle clé et l'action des ressorts de
rappel. Par action sur les vis 20-21, on ramène ensuite le
chariot 17 et, avec lui, les gorges secondaires 7', à la
position initiale. Après rotation de 90° de la nouvelle clé,
la serrure est réglée à la nouvelle combinaison.After returning the key to the rest position and having it
extracted, just insert a new key to a
different combination, and rotate it 90 °. The
La serrure qui vient d'être décrite peut commander, de manière classique, un pêne demi-tour et/ou des tringles verticales. The lock which has just been described can control, from classic way, a latch bolt and / or rods vertical.
Dans la variante des figures 4 et 5, l'organe de déplacement
du chariot 17 est constitué par un axe de commande 30 rotatif
dont la tête 31 accessible de l'extérieur, est fixe en
translation. L'axe 30 porte deux bouts de tubes 32 et 33
fixés par des chevilles 34. Entre les bouts de tubes 32 et 33
est montée une pièce 35 solidaire du chariot 17.In the variant of FIGS. 4 and 5, the displacement member
of the
La pièce 35 porte un évidemment tronconique 36 avec lequel
coopère une pointe de guidage et de butée 37 du bout de tube
32. La pièce 35 porte, en outre, sur sa face opposée à
l'évidement 36, une rampe 38 avec laquelle coopère une dent
39 du bout du tube 33.The
En position de repos (figure 4), la dent 39 est en dehors de
la rampe 38 et la pointe 37 est engagée dans l'évidement
conique 37.In the rest position (Figure 4), the
Si on fait subir à l'axe 30 une rotation, la dent 39 coopère
avec la rampe 38 et la pièce 35, solidaire du chariot 17,
subit une translation vers la droite (sur le dessin). Les
gorges secondaires sont écartées des gorges principales et le
changement de combinaison peut intervenir comme précédemment.If the
