Description

La présente invention se rapporte, d'une part, à un coffre principal destiné à être intégré dans une serrure multipoints comportant au moins un coffre secondaire, ledit coffre principal comprenant un pêne de condamnation apte à entraîner au moins une tringle de commande prévue pour être reliée au coffre secondaire, et d'autre part, à une serrure multipoints comprenant un tel coffre principal.The present invention relates, on the one hand, to a main trunk intended to be integrated in a multi-point lock comprising at least one secondary trunk, said main trunk comprising a locking bolt capable of driving at least one control rod intended to be connected to the secondary chest, and secondly, to a multi-point lock including such a main chest.

On connaît du document FR2 722 824 un dispositif de blocage des tringles de commande d'un coffre principal en cas d'effraction. Ce dispositif comprend une came de blocage qui, en cas de destruction des arbres de gorge du pêne, permet d'empêcher l'actionnement des tringles de commande des coffres secondaires.Document is known FR2 722 824 a locking device of the control rods of a main trunk in case of break-in. This device comprises a locking cam which, in the event of destruction of the groove shafts of the bolt, makes it possible to prevent the actuation of the control rods of the secondary chests.

Bien souvent, un cambrioleur désirant pénétrer à l'intérieur d'un local commence par fracturer le barillet afin de l'extraire du coffre principal de la serrure multipoints. Une fois que cette tâche a été accomplie, le cambrioleur a accès aux organes internes du coffre principal et peut donc facilement procéder au déverrouillage du pêne jusqu'alors logé dans la gâche fixée dans le chambranle de la porte à protéger. Pour cela, le cambrioleur soulève généralement la gorge dont les dents coopèrent avec la denture présentée par la queue du pêne. Le pêne n'est donc plus bloqué en translation et le cambrioleur peut le placer dans sa position de repos. Cette opération de déverrouillage du pêne logé dans le coffre principal provoque alors, par l'intermédiaire des tringles de commande, le déverrouillage du pêne logé dans chacun des coffres secondaires. Ainsi, il suffit au cambrioleur de placer le pêne du coffre principal dans sa position de repos pour désactiver totalement la serrure multipoints.Often, a burglar wishing to penetrate inside a room begins by fracturing the barrel to extract it from the main chest of the multi-point lock. Once this task has been completed, the burglar has access to the internal organs of the main safe and can therefore easily unlock the bolt previously housed in the keeper fixed in the door jamb to protect. For this, the burglar usually raises the groove whose teeth cooperate with the teeth presented by the tail of the bolt. The bolt is no longer locked in translation and the burglar can place it in its rest position. This unlocking operation of the bolt housed in the main trunk then causes, via the control rods, the unlocking of the bolt housed in each of the secondary chests. Thus, it is sufficient for the burglar to place the bolt of the main chest in its rest position to completely disable the multi-point lock.

La présente invention a pour but de résoudre le problème évoqué précédemment, et consiste pour cela en un coffre principal selon la revendication 1.The present invention aims to solve the problem mentioned above, and for this purpose consists of a main safe according to claim 1.

Ainsi, dans un tel coffre, l'ablation du barillet n'entraîne nullement le déblocage de la butée de tringle : de par la présence des moyens de rappel élastique, cette butée de tringle demeure en position bloquée, et empêche le retour des tringles de commande et du pêne vers leur position déverrouillée, et donc l'ouverture de la porte équipée de ce dispositif.Thus, in such a box, the ablation of the barrel does not involve the release of the bead stop: by the presence of the elastic return means, this bead stop remains in the locked position, and prevents the return of the rods of control and bolt to their unlocked position, and thus the opening of the door equipped with this device.

Selon un mode de réalisation préférée, la tringle de commande est équipée d'une plaquette d'arrêt présentant un premier chant, et la butée de tringle demeure au contact de ce premier chant sous l'action desdits moyens de rappel élastique. Cette plaquette d'arrêt est de préférence constituée par une pièce rapportée et fixée dans la tringle de commande, mais il doit être bien compris qu'elle pourrait être ménagée directement dans la tringle de commande.According to a preferred embodiment, the control rod is equipped with a stop plate having a first edge, and the bead stop remains in contact with the first edge under the action of said elastic return means. This stop plate is preferably constituted by an insert and fixed in the control rod, but it should be understood that it could be formed directly in the control rod.

Avantageusement, l'organe de commande est réalisé à l'aide d'un panneton équipé d'une came. De préférence, cette came est réalisée à l'aide d'une pièce semi-circulaire pourvue d'une couronne périphérique. Avantageusement encore, la butée de tringle possède un bord incurvé apte à coopérer avec ladite came.Advantageously, the control member is made using a bit equipped with a cam. Preferably, this cam is made using a semi-circular piece provided with a peripheral ring. Advantageously, the bead stop has a curved edge adapted to cooperate with said cam.

Préférentiellement, une échancrure principale est ménagée dans le premier chant de la plaquette d'arrêt, et la butée de tringle comporte avantageusement un épaulement externe apte à venir se loger dans cette échancrure principale lorsque le pêne est en position de verrouillage.Preferably, a main notch is formed in the first edge of the stop plate, and the bead stop advantageously comprises an outer shoulder adapted to be housed in the main notch when the bolt is in the locking position.

Préférentiellement encore, la plaquette d'arrêt présente un deuxième chant parallèle au premier dans lequel est ménagée une échancrure secondaire. De plus, la butée de tringle peut comporter un ergot d'extrémité apte à venir se loger dans l'échancrure secondaire de la plaque d'arrêt lorsque la butée de tringle est forcée à effectuer une course supérieure à celle prévue pour revenir en position d'escamotage.Preferably again, the stop plate has a second edge parallel to the first in which is formed a secondary notch. In addition, the bead stop may comprise an end pin adapted to be housed in the secondary notch of the stop plate when the bead stop is forced to perform a greater stroke than expected to return to position d retraction.

La présente invention se rapporte également à une serrure multipoints, caractérisée en ce qu'elle comprend un coffre principal selon l'invention relié à au moins un coffre secondaire par l'intermédiaire d'une tringle de commande.The present invention also relates to a multi-point lock, characterized in that it comprises a main trunk according to the invention connected to at least one secondary trunk by means of a control rod.

L'invention sera mieux comprise à l'aide de la description détaillée qui est exposée ci-dessous en regard du dessin annexé dans lequel :

  • La figure 1 est une vue en perspective du coffre principal d'une serrure multipoints selon un mode de réalisation préféré de l'invention, avec omission du barillet et d'une partie d'un flasque.

Un coffre principal 1 d'une serrure multipoints selon un mode de réalisation préféré de l'invention, tel que représenté aux figures 1, 5 et 7, est réalisé à partir de deux flasques 2 assemblés l'un à l'autre.A main chest 1 of a multi-point lock according to a preferred embodiment of the invention, as shown in FIGS. figures 1 , 5 and 7 , is made from two flanges 2 assembled to one another.

Le coffre principal 1 est rattaché à une têtière 3, et renferme notamment les pièces bien connues de l'homme du métier habituellement utilisées pour assurer le verrouillage et le déverrouillage d'un pêne 4 de condamnation.The main chest 1 is attached to a headrest 3, and includes the parts well known to those skilled in the art usually used to ensure the locking and unlocking a locking bolt 4.

Chaque flasque 2 comporte, en partie basse, une ouverture centrale 5 adaptée à la section d'un barillet (non représenté), ce dernier présentant une première partie et une seconde partie séparées l'une de l'autre par un panneton 6 médian mobile en rotation.Each flange 2 comprises, in the lower part, a central opening 5 adapted to the section of a barrel (not shown), the latter having a first portion and a second portion separated from one another by a mobile median bit 6 in rotation.

Une fois que le barillet a traversé les ouvertures centrales 5 des deux flasques 2, le panneton 6 est logé dans ledit coffre principal 1, et la première partie et la seconde partie du barillet font saillie respectivement d'un côté et de l'autre dudit coffre principal 1.Once the barrel has passed through the central openings 5 of the two flanges 2, the bit 6 is housed in said main chest 1, and the first portion and the second portion of the barrel protrude respectively from one side and the other of said main chest 1.

De façon classique, le panneton 6 est destiné à coopérer avec une gorge 7 lorsqu'il est entraîné en rotation à l'aide d'une clé (non représentée) introduite dans le barillet. Comme représenté plus particulièrement aux figures 1 et 8, cette gorge 7 est constituée par une plaque possédant une face interne disposée en regard de la queue 9 du pêne 4. Cette gorge 7 présente une lumière oblongue 8 traversée par un axe 10 transversal solidaire du coffre principal 1. De plus, en partie haute de sa face interne, la gorge 7 comprend un épaulement 11 faisant saillie dans lequel est creusé un évidement afin de constituer un logement apte à coopérer avec la denture 12 de la queue 9 du pêne 4. Cet épaulement 11 est surmonté par un téton sur lequel est rapporté un ressort de compression 14 renvoyant constamment la gorge 7 vers la queue 9 du pêne 4.In a conventional manner, the bit 6 is intended to cooperate with a groove 7 when it is rotated by means of a key (not shown) introduced into the barrel. As shown more particularly in figures 1 and 8 , this groove 7 is constituted by a plate having an internal face disposed opposite the shank 9 of the bolt 4. This groove 7 has an oblong slot 8 traversed by a transverse axis 10 secured to the main trunk 1. In addition, in the upper part its groove 7 comprises a protruding shoulder 11 in which is hollowed a recess in order to constitute a housing adapted to cooperate with the toothing 12 of the shank 9 of the bolt 4. This shoulder 11 is surmounted by a nipple on which is reported a compression spring 14 constantly returning the groove 7 to the tail 9 of the bolt 4.

De plus, une came 15 semi-circulaire munie d'une couronne 16 périphérique est introduite dans le coffre principal 1. Cette came 15 est conçue de façon à présenter, une fois qu'elle est correctement positionnée autour du panneton 6, une première extrémité 17 et une seconde extrémité 18 situées sur la trajectoire circulaire dudit panneton 6.In addition, a semicircular cam 15 provided with a peripheral ring 16 is introduced into the main box 1. This cam 15 is designed to have, once it is correctly positioned around the bit 6, a first end 17 and a second end 18 located on the circular path of said blade 6.

De façon classique, le pêne 4 est doté d'un plot d'entraînement 19 qui est engagé dans une ouverture 20 présentée par une plaque de manoeuvre 21 apte à pivoter autour d'un axe 22 solidaire du coffre principal 1. De plus, cette plaque de manoeuvre 21 possède, d'une part, une première fente 24 dans laquelle est introduite un axe 25 traversant une perforation présentée par une première branche 26 verticale d'une tringle de commande 27, et d'autre part, une seconde fente 28 dans laquelle est glissé un ergot 29 solidaire d'un bras de commande 30 rattaché à une première tige de commande 31. Comme il est possible de le déduire de la figure 1, la tringle de commande 27 comporte une seconde branche 32 verticale dont l'extrémité inférieure est rattachée à une seconde tige de commande 33. Il doit être bien compris que la première tige de commande 31 et la seconde tige de commande 33 permettent chacune d'assurer la liaison mécanique entre le coffre principal 1 et un coffre secondaire particulier (non représenté).In a conventional manner, the bolt 4 is provided with a drive pad 19 which is engaged in an opening 20 presented by an actuating plate 21 adapted to pivot about an axis 22 integral with the main box 1. In addition, this operating plate 21 has, on the one hand, a first slot 24 into which is introduced an axis 25 passing through a perforation presented by a first vertical branch 26 of a control rod 27, and secondly, a second slot 28 in which is slipped a lug 29 secured to a control arm 30 attached to a first control rod 31. As can be deduced from the figure 1 , the control rod 27 has a second vertical branch 32 whose lower end is attached to a second control rod 33. It should be understood that the first control rod 31 and the second control rod 33 each enable ensure the mechanical connection between the main chest 1 and a particular secondary chest (not shown).

En se référant à la figure 3, on observe que les première et seconde branches 26, 32 de la tringle de commande 27 sont reliées l'une à l'autre par l'intermédiaire d'une partie centrale 34 sensiblement en forme d'équerre. Il est à noter que cette partie centrale 34 est représentée de façon tronquée aux figures 4, 6, et 8 à 10 afin de ne pas cacher les pièces situés derrière.Referring to the figure 3 it is observed that the first and second branches 26, 32 of the control rod 27 are connected to one another via a substantially shaped central portion 34 square. It should be noted that this central part 34 is truncated in the form of figures 4 , 6 , and 8 to 10 so as not to hide the rooms behind.

Cette partie centrale 34 comporte deux perforations dans chacune desquelles est introduite un plot 35 faisant saillie d'une plaquette d'arrêt 37 verticale comprenant une partie inférieure 38 de section élargie et une partie supérieure 39 de section réduite. Plus précisément, cette plaquette d'arrêt 37 présente, d'une part, un premier chant 40 vertical dans lequel a été ménagée une échancrure principale 41, et d'autre part, un deuxième chant 42 vertical dans lequel a été ménagée une échancrure secondaire 43. De plus, l'échancrure principale 41 est réalisée de façon à ce que le premier chant 40 comporte une face biseautée 51 au niveau de la transition entre la partie inférieure 38 et la partie supérieure 39 de la plaquette d'arrêt 37.This central portion 34 has two perforations in each of which is introduced a stud 35 projecting from a vertical stop plate 37 comprising a lower portion 38 of enlarged section and an upper portion 39 of reduced section. More specifically, this stop plate 37 has, on the one hand, a first vertical edge 40 in which has been formed a main notch 41, and secondly, a second vertical edge 42 in which has been formed a secondary notch 43. In addition, the main notch 41 is made so that the first edge 40 has a bevelled face 51 at the transition between the lower portion 38 and the upper portion 39 of the stop plate 37.

Par ailleurs, une butée de tringle 44 est positionnée transversalement à la tringle de commande 27. Plus précisément, cette butée de tringle 44 comprend une première partie 45 de section carrée qui est prolongée, au niveau d'un épaulement externe 46, par une seconde partie 47 réalisée sous la forme d'une plaquette verticale. La première partie 45 repose sur un ressort de compression 48 en appui contre la têtière 3, et la seconde partie 47 présente, d'une part, un ergot 49 d'extrémité, et d'autre part, un bord 50 incurvé situé en regard de la couronne 16 de la came 15.Furthermore, a bead stop 44 is positioned transversely to the control rod 27. More specifically, this bead stop 44 comprises a first portion 45 of square section which is extended, at an outer shoulder 46, by a second part 47 made in the form of a vertical plate. The first part 45 rests on a compression spring 48 bearing against the headrest 3, and the second part 47 has, on the one hand, an end lug 49, and on the other hand, a curved edge 50 located opposite of the ring 16 of the cam 15.

Lorsque le pêne 4 du coffre principal 1 est en position de déverrouillage, ce qui est le cas aux figures 1 et 4, la butée de tringle 44 est renvoyée vers la came 15 sous l'effet du ressort de compression 48. Ce faisant, l'épaulement externe 46 vient en butée contre le premier chant 40 de la partie inférieure 38 de la plaquette d'arrêt 37. Le panneton 6 est dirigé vers le bas, légèrement décalé par rapport à l'ouverture centrale 5. Dans cette position, la came 15 repose sur le panneton 6 par l'intermédiaire de sa première extrémité 17, et demeure à distance du bord 50 incurvé de la butée de tringle 44.When the bolt 4 of the main trunk 1 is in the unlocking position, which is the case in the figures 1 and 4 , the rod stop 44 is returned to the cam 15 under the effect of the compression spring 48. In doing so, the outer shoulder 46 abuts against the first edge 40 of the lower portion 38 of the stop plate 37 The bit 6 is directed downwards, slightly offset from the central opening 5. In this position, the cam 15 rests on the bit 6 via its first end 17, and remains at a distance from the edge 50 curved rod stop 44.

Comme on peut le déduire des figures 5 à 9, lorsqu'une personne introduit la clé dans le barillet afin de placer le pêne 4 en position de verrouillage, le panneton 6 et la came 15 sont entraînés en rotation. Par suite, le panneton 6 vient s'engager dans la denture 12 de la queue 9 du pêne 4, ce qui force ce dernier à se translater latéralement. Ce faisant, la plaque de manoeuvre 21 est entraînée en rotation autour de son axe 25 par l'ergot d'entraînement 19 solidaire du pêne 4, ce qui provoque en définitive la translation vers le bas de la tringle de commande 27. Comme représenté aux figures 8 et 9, lorsque le panneton 6 retrouve sa position d'origine et que le pêne 4 est en position de verrouillage, l'épaulement externe 46, sous l'effet du ressort de compression 48, vient alors en butée contre le premier chant 40 de la partie supérieure 39 de la plaquette d'arrêt 37. La face biseautée 51 permet de faciliter la venue de l'épaulement externe 46 dans l'échancrure 41.As can be deduced from Figures 5 to 9 when a person enters the key in the barrel to place the bolt 4 in the locking position, the bit 6 and the cam 15 are rotated. As a result, the bit 6 engages in the toothing 12 of the tail 9 of the bolt 4, which forces the latter to translate laterally. In doing so, the operating plate 21 is rotated about its axis 25 by the lug 19 secured to the bolt 4, which ultimately causes the downward translation of the control rod 27. As shown in FIGS. figures 8 and 9 when the bit 6 returns to its original position and the bolt 4 is in the locking position, the outer shoulder 46, under the effect of the compression spring 48, then abuts against the first edge 40 of the part 39 of the stop plate 37. The tapered face 51 facilitates the coming of the outer shoulder 46 into the notch 41.

Par conséquent, même si un cambrioleur fracture le barillet, il ne lui suffit pas de désengager la gorge 7 de la denture 12 de la queue 9 du pêne 4 pour pourvoir déplacer ce dernier en translation. En effet, l'échancrure principale 41 est en butée contre l'épaulement externe 46 de la butée de tringle 44 et interdit toute remontée de la tringle de commande 27. S'il veut procéder à l'ouverture du pêne 4, le cambrioleur doit donc encore escamoter la butée de tringle 44 afin de pouvoir libérer la plaquette d'arrêt 37. Néanmoins, cette manipulation est très délicate à réaliser car, comme représenté à la figure 10, si le cambrioleur force la butée de tringle 44 à effectuer une course très légèrement supérieure à celle prévue pour revenir en position d'escamotage, l'ergot 49 d'extrémité vient se loger dans l'échancrure secondaire 43 pratiquée dans le deuxième chant 42, ce qui a pour effet de bloquer la remontée de la tringle de commande 27.Therefore, even if a burglar fractures the barrel, it is not enough for him to disengage the groove 7 of the toothing 12 of the tail 9 of the bolt 4 to be able to move the latter in translation. Indeed, the main notch 41 is in abutment against the outer shoulder 46 of the bead stop 44 and prohibits any raising of the control rod 27. If it wants to proceed to the opening of the bolt 4, the burglar must therefore still retract the bead stop 44 in order to release the stop plate 37. Nevertheless, this manipulation is very difficult to perform because, as shown in FIG. figure 10 if the burglar forces the bead stopper 44 to perform a stroke slightly greater than that intended to return to the retracted position, the end lug 49 is housed in the secondary notch 43 formed in the second edge 42 , which has the effect of blocking the raising of the control rod 27.

Lorsqu'une personne tourne la clé en sens inverse afin de replacer le pêne 4 en position de déverrouillage, le panneton 6 est entraîné en rotation inverse et vient au contact de la seconde extrémité 18 de la came 15. Lorsque le panneton vient s'engager dans la denture 12 de la queue 9 du pêne 4, la couronne 16 de la came 15 vient alors exercer des contraintes sur le bord 50 incurvé de la butée de tringle 44 qui est en position avancée. La butée de tringle 44 est par conséquent amenée, sous l'action de la came 15, à se déplacer à l'encontre du ressort de compression 48 jusqu'à retrouver sa position d'escamotage. Ceci permet en définitive de libérer la plaquette d'arrêt 37 de l'épaulement externe 46. Il en découle que la tringle de commande 27 peut se translater vers le haut conséquemment au déplacement latéral du pêne 4. Une fois que le panneton 6 a retrouvé sa position d'origine, le pêne 4 est en position de déverrouillage dans le coffre principal 1, et l'épaulement externe 46 est en butée contre le premier chant 40 de la partie inférieure 38 de la plaquette d'arrêt 37. La face biseautée 51 permet de faciliter la sortie de l'épaulement externe 46 hors de l'échancrure 41.When a person turns the key in the opposite direction in order to replace the bolt 4 in the unlocked position, the bit 6 is driven in reverse rotation and comes into contact with the second end 18 of the cam 15. When the bit is engaged in the toothing 12 of the shank 9 of the bolt 4, the ring 16 of the cam 15 then exerts stresses on the curved edge 50 of the bead stop 44 which is in the advanced position. The stop rod 44 is therefore caused, under the action of the cam 15, to move against the compression spring 48 to find its retracted position. This finally allows the stop plate 37 to be released from the outer shoulder 46. It follows that the control rod 27 can translate upwards as a result of the lateral displacement of the bolt 4. Once the bit 6 has found its original position, the bolt 4 is in the unlocked position in the main trunk 1, and the outer shoulder 46 is in abutment against the first edge 40 of the lower portion 38 of the stop plate 37. The beveled face 51 facilitates the exit of the outer shoulder 46 from the notch 41.
