The device according to the invention is especially suitable for multi-point stud locks. It is simple to use by a handy man and also makes it possible to safeguard the aesthetic appearance of the opening frame. <IMAGE>

Description

Le domaine de l'invention concerne les dispositifs de fermeture de sécurité adaptés sur des ouvrants (porte, porte de fenêtres, fenêtre), du type serrure comprenant une timonerie commandant plusieurs points de verrouillage. De façon courante la timonerie comporte au moins une tringle se déplaçant en translation parallèlement au champ de l'ouvrant et présentant généralement une pluralité de lumières disposées en alignement sur la longueur de ladite tringle. Les lumières servent au passage de vis de fixation d'une pièce de fermeture maintenant ladite tringle plaquée le long du champ de la porte tout en permettant le mouvement en translation de la tringle.The field of the invention relates to safety closing devices adapted to openings (door, window door, window), of the lock type comprising a wheelhouse controlling several locking points. Usually the wheelhouse has at least one rod moving in translation parallel to the opening field and generally having a plurality of lights arranged in alignment along the length of said rod. The lights are used for the passage of fixing screws for a closing piece holding said rod pressed along the field of the door while allowing the rod to move in translation.

Souvent ces dispositifs de fermeture multipoints d'origine sont renforcés par un ou plusieurs dispositifs de fermeture du type verrous montés sur l'ouvrant et constitués d'un organe de commande qui agit sur un pêne, le pêne pouvant se loger par translation dans une gâche fixée à l'huisserie. Cependant, ces dispositifs de fermeture ne confèrent pas au dispositif de fermeture multipoints d'origine une meilleure protection en verrouillage. Plus particulièrement, ils n'empêchent pas tout actionnement du dispositif de fermeture d'origine. Ils sont par ailleurs peu esthétiques.Often these original multipoint closing devices are reinforced by one or more locking devices of the bolt type mounted on the opening and consist of a control member which acts on a bolt, the bolt being able to be housed by translation in a strike. fixed to the frame. However, these closing devices do not give the original multipoint closing device better locking protection. More particularly, they do not prevent any actuation of the original closing device. They are also unattractive.

L'invention se propose donc de résoudre le problème de doubler le verrouillage du dispositif de fermeture multipoints d'origine par blocage de la course de la tringle en position verrouillée c'est-à-­dire en position de fermeture du dispositif d'origine.The invention therefore proposes to solve the problem of doubling the locking of the original multipoint closing device by blocking the travel of the rod in the locked position, that is to say in the closing position of the original device.

Il est donc souhaitable de disposer d'un locqueteau additionnel adapté au dispositif de fermeture d'origine qui utilise par exemple les lumières disposées sur la tringle (à défaut de lumières d'origine il conviendra d'en pratiquer une). Il est également souhaitable que la position verrouillée de ce locqueteau additionnel interdise le mouvement de la tringle dans le sens ouverture, mais puisse autoriser ce mouvement dans le sens fermeture.It is therefore desirable to have an additional latch adapted to the original closing device which uses for example the lights arranged on the rod (in the absence of original lights it will be advisable to practice one). It is also desirable that the locked position of this additional hook prevents movement of the rod in the opening direction, but can allow this movement in the closing direction.

Le locqueteau additionnel selon l'invention est notamment remarquable en ce qu'il est constitué d'un levier de forme sensiblement triangulaire monté à articulation sur un axe au droit d'une desdites lumières, ledit levier étant prolongé sur un de ses côtés par une dent de levier de sorte que par pivotement du levier autour de son axe quand le dispositif de fermeture multipoints est en position de fermeture, ladite dent de levier s'engage dans la lumière, d'un moyen de commande du levier permettant de choisir entre un état de verrouillage et un état de déverrouillage du locqueteau additionnel, deux butées de course du levier disposées respectivement de part et d'autre d'une extrémité du levier, deux flasques séparés par un jeu d'entretoises et maintenus parallèles l'un par rapport à l'autre.The additional latch according to the invention is notably remarkable in that it consists of a lever of substantially triangular shape mounted at articulation on an axis in line with one of said slots, said lever being extended on one of its sides by a lever tooth so that by pivoting the lever about its axis when the multipoint closing device is in the closed position, said lever tooth engages in the light, with a lever control means making it possible to choose between a locking state and unlocking state of the additional latch, two lever travel stops respectively disposed on either side of one end of the lever, two flanges separated by a set of spacers and kept parallel to each other to the other.

Lorsque la dent de levier est engagée dans la lumière de la tringle par pivotement du levier autour de son axe, le mouvement en translation dans le sens fermeture ouverture de la tringle est empêché par la dent de levier, ce qui interdit tout déverrouillage du dispositif de fermeture multipoints. Par contre, il est toujours possible de manoeuvrer la tringle jusqu'à sa position de fermeture maximale quelle que soit la position du locqueteau additionnel. Pour autoriser le mouvement en translation dans le sens fermeture ouverture de la tringle, il suffit de dégager la dent de levier de la lumière, puis actionner le dispositif de commande du dispositif de fermeture multipoints.When the lever tooth is engaged in the opening of the rod by pivoting the lever around its axis, the translational movement in the opening and closing direction of the rod is prevented by the lever tooth, which prohibits any unlocking of the device. multi-point closure. On the other hand, it is always possible to maneuver the rod to its maximum closed position regardless of the position of the additional latch. To authorize the movement in translation in the opening direction of the rod, it is sufficient to disengage the lever tooth from the light, then actuate the control device of the multi-point closing device.

La géométrie du levier du locqueteau additionnel est tel que l'effort d'ouverture du dispositif de fermeture multipoints d'origine, lorsque le locqueteau est dans sa position verrouillée, tend à accroître la stabilité dudit locqueteau dans cette position.The geometry of the lever of the additional catch is such that the opening force of the original multipoint closing device, when the latch is in its locked position, tends to increase the stability of said latch in this position.

Selon un mode de réalisation de l'invention, le verrou comporte une retenue à bille coopérant avec des moyens de positionnement de la bille, de sorte à positionner le levier dans un état stable de verrouillage ou de déverrouillage. De cette manière, la position du levier dans l'un des deux états stables est toujours assurée, évitant ainsi que le locqueteau additionnel ne se verrouille malencontreusement par choc, gravité etc...According to one embodiment of the invention, the lock comprises a ball retainer cooperating with means for positioning the ball, so as to position the lever in a stable state of locking or unlocking. In this way, the position of the lever in one of the two stable states is always ensured, thus preventing the additional latch from accidentally locking by shock, gravity, etc.

Selon une autre caractéristique de l'invention, la retenue à bille est constituée d'un moyen élastique travaillant en compression et repoussant la bille, le moyen élastique et la bille étant placée dans un évidement cylindrique borgne, réalisé sur un des côtés du levier, de diamètre sensiblement supérieur au diamètre de la bille.According to another characteristic of the invention, the ball retainer consists of an elastic means working in compression and repelling the ball, the elastic means and the ball being placed in a blind cylindrical recess, produced on one of the sides of the lever, of diameter substantially greater than the diameter of the ball.

Selon encore une autre caractéristique de l'invention, les moyens de positionnement de la bille sont constitués de deux alésages réalisés dans un des flasques, en contact étroit avec la bille, le diamètre desdits alésages étant sensiblement inférieur au diamètre de la bille.According to yet another characteristic of the invention, the means for positioning the ball consist of two bores made in one of the flanges, in close contact with the ball, the diameter of said bores being substantially less than the diameter of the ball.

Ces caractéristiques et avantages de l'invention ressortiront mieux de la description qui va suivre concernant une forme de réalisation préférentielle de l'invention donnée à titre d'exemple non limitatif et illustrée sur les dessins ci-joints dans lesquels :

These characteristics and advantages of the invention will emerge more clearly from the description which follows concerning a preferred embodiment of the invention given by way of nonlimiting example and illustrated in the attached drawings in which:

Cette description s'adresse à un type de serrure à larder, dont le locqueteau additionnel va sauvegarder l'esthétique tout en accroissant son efficacité.This description is intended for a type of mortise lock, the additional latch of which will safeguard the aesthetic while increasing its efficiency.

La plupart des systèmes de fermeture multipoints à larder 5 sont dotés d'une timonerie d'origine 2 comportant au moins une tringle 7 de commande de pênes 3 à partir d'un organe central. L'ensemble de ce dispositif de fermeture vient s'adapter notamment à l'intérieur d'une porte 1 comme cela est montré dans la figure 1. La tringle mobile 7 de commande des pênes glisse à l'intérieur d'une rainure formée dans le champ 4 de la porte et est maintenue le long de ce champ par une pièce de fermeture 6 fixée le long dudit champ 4 de la porte au moyen de vis 8 de fixation visibles en figures 3 et 4.Most of the multi-point larding closure systems 5 are fitted with an original wheelhouse 2 comprising at least one rod 7 for controlling the bolts 3 from a central member. The assembly of this closing device is adapted in particular inside a door 1 as shown in FIG. 1. The movable rod 7 for controlling the bolts slides inside a groove formed in the field 4 of the door and is held along this field by a closing piece 6 fixed along the said field 4 of the door by means of fixing screws 8 visible in FIGS. 3 and 4.

La tringle 7 comporte une pluralité de lumières 9 disposées en alignement sur sa longueur et permettant à celle-ci de coulisser le long du champ 4 sans être gênée par les vis 8 de fixation.The rod 7 comprises a plurality of lights 9 arranged in alignment along its length and allowing the latter to slide along the field 4 without being hindered by the fixing screws 8.

Conformément à la présente invention, le locqueteau additionnel est placé de façon préférentielle, sensiblement à proximité de la tringle mobile 7 comme le montre la figure 5. Le levier 10 du locqueteau additionnel est monté à articulation sur un axe 12 au droit d'une desdites lumières 9 aménagées dans la tringle 7, l'axe 12 étant perpendiculaire au plan de la porte 1. Le levier est prolongé par une dent de levier 11 dont l'épaisseur est inférieure à la largeur de la lumière 9 de sorte que par pivotement du levier 10 dans le sens inverse des aiguilles d'une montre, la dent de levier 11 s'engage dans la lumière 9 de la tringle 7, celle-ci étant dans la position abaissée correspondant à la fermeture du dispositif multipoints 5. La disposition dent de levier engagée dans la lumière 9 bloque le mouvement en translation vers le haut de ladite tringle 7 et par répercussion interdit l'actionnement de la serrure 5 dans le sens ouverture mais autorise son actionnement dans le sens fermeture (cas A). Le levier 10 est mu par exemple (en position abaissée ou en position relevée correspondant respectivement à la position verrouillée et la position déverrouillée du locqueteau additionnel), par un dispositif de commande 16 du type barillet à canon. De façon à arrêter la course du levier 10 soit en position haute, soit en position basse, on prévoit deux butées 14 et 13 disposées de part et d'autre d'une extrémité du levier comme visible en figure 5. L'axe 12 et les deux butées 14 et 13 jouent le rôle d'entretoises séparant deux flasques 17₁ et 17₂ maintenus parallèles l'un par rapport à l'autre et renfermant l'ensemble du mécanisme du locqueteau additionnel à larder dans la porte 1. On positionne ledit levier 10 par rapport à ladite lumière 9 de sorte qu'en position abaissée de la tringle 7 correspondant à la position de fermeture du dispositif de fermeture multipoints 5, ladite dent de levier 11 peut entrer dans la lumière 9 et en sortir par simple rotation dudit levier 10 autour de son axe 12.In accordance with the present invention, the additional locqueteau is preferably placed, substantially close to the movable rod 7 as shown in FIG. 5. The lever 10 of the additional locqueteau is articulated on an axis 12 in line with one of the said lights 9 arranged in the rod 7, the axis 12 being perpendicular to the plane of the door 1. The lever is extended by a lever tooth 11 whose thickness is less than the width of the opening 9 so that by pivoting the lever 10 anticlockwise, the tooth lever 11 engages in the slot 9 of the rod 7, the latter being in the lowered position corresponding to the closure of the multipoint device 5. The lever tooth arrangement engaged in the slot 9 blocks the movement in upward translation of said rod 7 and by repercussion prohibits the actuation of the lock 5 in the opening direction but authorizes its actuation in the closing direction (case A). The lever 10 is moved for example (in the lowered position or in the raised position corresponding respectively to the locked position and the unlocked position of the additional latch), by a control device 16 of the barrel barrel type. In order to stop the stroke of the lever 10 either in the high position or in the low position, two stops 14 and 13 are provided, arranged on either side of one end of the lever as visible in FIG. 5. The axis 12 and the two stops 14 and 13 act as spacers separating two flanges 17₁ and 17₂ kept parallel to each other and enclosing the entire mechanism of the additional latch to be larded in the door 1. The said lever is positioned 10 relative to said lumen 9 so that in the lowered position of the rod 7 corresponding to the closed position of the multi-point closing device 5, said lever tooth 11 can enter and exit lumen 9 by simple rotation of said lever 10 around its axis 12.

Comme visible sur la figure 5, la dent de levier 11 présente une forme sensiblement triangulaire, la base 23 de la dent de levier 11 étant sensiblement adjacente à la base 24 de la lumière 9 dans la position verrouillée du locqueteau additionnel et la distance entre l'axe d'articulation 12 du levier et l'extrémité 25 de la dent de levier 11 étant sensiblement inférieure à la distance entre l'axe d'articulation 12 et le bord extérieur 26 de la base 24 de la lumière 9.As can be seen in FIG. 5, the lever tooth 11 has a substantially triangular shape, the base 23 of the lever tooth 11 being substantially adjacent to the base 24 of the lumen 9 in the locked position of the additional latch and the distance between the hinge pin 12 of the lever and the end 25 of the lever tooth 11 being substantially less than the distance between the hinge pin 12 and the outer edge 26 of the base 24 of the slot 9.

Un des flasques 17₁ ou 17₂ peut comporter un bord tombé permettant la fixation du locqueteau additionnel à la serrure d'origine au moyen de deux vis 22. Cette fixation n'est utile que pour faciliter le montage sur l'ouvrant.One of the flanges 17₁ or 17₂ may have a dropped edge allowing the attachment of the additional latch to the original lock by means of two screws 22. This attachment is only useful for facilitating mounting on the opening.

Ledit levier 10 peut comporter une retenue à bille 15 permettant un maintien en position stable dudit levier 10 comme visible en figures 5 et 6. Ladite retenue à bille consiste en un moyen élastique 19 du type ressort. Ledit ressort 19 étant logé dans un évidement cylindrique borgne 21, exerce une force de compression sur la bille 18 arrêtée par le flasque 17₁. Le diamètre de l'évidement cylindrique 21 est sensiblement supérieur au diamètre de la bille 18. Cette retenue à bille 15 coopère avec des moyens de positionnement stables qui correspondent aux deux alésages 20₁ et 20₂ réalisés dans le flasque 17₁ en contact étroit avec la bille 18. Le diamètre de ces alésages est sensiblement inférieur au diamètre de ladite bille 18. Les axes respectifs des deux alésages 20₁ et 20₂ se trouvent disposés sur la circonférence d'un cercle dont le centre correspond à l'axe d'articulation 12 du levier 10 et dont le rayon est égal à la distance entre l'axe 12 et l'axe de l'évidement cylindrique 21, les deux alésages 20₁ et 20₂ déterminant respectivement des points de blocage du levier 10 en position verrouillée et en position déverrouillée du locqueteau additionnel. La position de ces alésages est de nature à forcer le positionnement du levier dans l'une des positions stables et notamment dans le cas de mouvement où le locqueteau est en position verrouillé alors que la serrure d'origine n'est pas en position fermée. Les caractéristiques du ressort sont choisies de façon à ce que le levier puisse recouvrer la position stable la plus proche de celle commandée et notamment dans le mouvement dénommé: cas A.Said lever 10 may include a ball retainer 15 enabling said lever 10 to be held in a stable position as shown in FIGS. 5 and 6. Said ball retainer consists of an elastic means 19 of the spring type. Said spring 19 being housed in a blind cylindrical recess 21, exerts a compressive force on the ball 18 stopped by the flange 17₁. The diameter of the cylindrical recess 21 is substantially greater than the diameter of the ball 18. This ball retainer 15 cooperates with stable positioning means which correspond to the two bores 20₁ and 20₂ produced in the flange 17₁ in close contact with the ball 18 The diameter of these bores is substantially less than the diameter of said ball 18. The respective axes of the two bores 20₁ and 20₂ are arranged on the circumference of a circle whose center corresponds to the axis of articulation 12 of the lever 10 and whose radius is equal to the distance between the axis 12 and the axis of the cylindrical recess 21, the two bores 20₁ and 20₂ respectively determining the locking points of the lever 10 in the locked position and in the unlocked position of the additional latch . The position of these bores is such as to force the positioning of the lever in one of the stable positions and in particular in the case of movement where the latch is in the locked position while the original lock is not in the closed position. The characteristics of the spring are chosen so that the lever can recover the stable position closest to that commanded and in particular in the movement called: case A.

De manière préférentielle, le profil des flasques 17₁ et 17₂ épouse le profil du barillet de commande 16 pour simplifier leur mise en place et définir le positionnement respectif des sous ensembles : locqueteau, barillet.Preferably, the profile of the flanges 17₁ and 17₂ follows the profile of the control barrel 16 to simplify their positioning and define the respective positioning of the sub-assemblies: locqueteau, barrel.

Outre la sauvegarde de l'esthétique initiale de la serrure à larder le locqueteau additionnel est d'une mise en oeuvre simple ne nécessitant qu'un outillage banal donc ouvert au domaine du bricolage.In addition to safeguarding the initial aesthetics of the mortise lock, the additional lock is easy to implement, requiring only a trivial tool, therefore open to the DIY sector.
