Abstract

The door (26), which is equipped with a lock (32) actuated by a key to operate a bolt (34), has an auxiliary locking mechanism formed by two or more horizontal sliders (10,12) connected by vertical bars (14,16). One of the vertical bars (16), which lies adjacent to the lock, is connected to the main bolt (34), and the ends of the sliders have additional bolts (42) engaging with sockets (28,30,48,50) on each side of the door. The horizontal sliders move in guides (18,20,22,24) containing balls, and the two bolts adjacent to the hinged side of the door have pivots (44,46) which align with the door hinges (36,38) when the lock is not engaged. The sockets on the same side have springs (52) in them which tend to push the sliders towards the closed position.

Description

La présente invention concerne un dispositif de protection d'une ouverture d'habitation, et en particulier un dispositif destiné à renforcer le verrouillage d'une porte déjà pourvue d'un verrou.The present invention relates to a device for protecting a residential opening, and in particular a device intended to reinforce the locking of a door already provided with a lock.

Pour éviter les effractions et les tentatives de cambriolage les portes d'appartement, de villas et d'habitation en général disposent de un ou plusieurs verrous de sécurité en plus de la fermeture classique de la porte.To avoid burglaries and burglary attempts, apartment, villa and apartment doors in general have one or more security locks in addition to the classic door closure.

De façon à renforcer le verrouillage, on trouve dans le commerce des systèmes dits à 3 ou 5 points constitués d'un verrou de sécurité actionnant plusieurs pênes s'engageant dans des gâches qui sont fixées à l'huisserie de la porte côté ouverture, sur la partie horizontale de l'huisserie au dessus de la porte et dans le sol en bas de la porte. Malheureusement, ce système est facilement contournable par un cambrioleur déterminé qui insère un levier du type pied de biche entre la porte et l'huisserie du côté opposé au verrou (à l'emplacement des gonds) et peut alors forcer la porte et faire sauter le système de fermeture.In order to reinforce the locking, there are commercially available systems known as 3 or 5 points consisting of a security lock actuating several bolts engaging in strikes which are fixed to the door frame of the opening side, on the horizontal part of the frame above the door and in the floor at the bottom of the door. Unfortunately, this system is easily circumvented by a determined burglar who inserts a crowbar-type lever between the door and the frame on the side opposite the lock (at the location of the hinges) and can then force the door and blow up the closing system.

On a donc songé à installer des systèmes comportant des gâches sur au moins deux côtés opposés de la porte , en plus du verrou existant. Le brevet français 2.396.855 décrit un système de ce type dans lequel la fermeture du verrou commande l'introduction de 4 pênes dans des gâches situées des 4 côtés de la porte. Malheureusement ce système est très complexe et comporte en outre un élément principal entraîné en rotation par la fermeture du verrou, ce mouvement de rotation étant transformé en translation des pênes par un jeu d'articulations. Il est clair qu'un tel système, de part sa complexité, est fragile et coûteux.Consideration has therefore been given to installing systems comprising strikes on at least two opposite sides of the door, in addition to the existing lock. French Patent 2,396,855 describes a system of this type in which the closing of the lock controls the introduction of 4 bolts into strikes situated on the 4 sides of the door. Unfortunately this system is very complex and further comprises a main element driven in rotation by the closing of the lock, this rotary movement being transformed into translation of the bolts by a set of articulations. It is clear that such a system, due to its complexity, is fragile and expensive.

C'est pourquoi le but de l'invention est de fournir un dispositif de protection d'une ouverture telle qu'une porte, simple et efficace et ne comportant aucune partie tournante.This is why the object of the invention is to provide a device for protecting an opening such as a door, simple and effective and comprising no rotating part.

Un autre but de l'invention est de fournir un dispositif de renforcement du verrouillage d'une porte pouvant être installé facilement sur une porte sans avoir à changer ou à modifier le verrou existant.Another object of the invention is to provide a device for reinforcing the locking of a door which can be easily installed on a door without having to change or modify the existing lock.

L'objet de l'invention est donc un dispositif de protection pour le renforcement d'une ouverture telle qu'une porte du type comportant un verrou. Le dispositif comprend au moins un coulisseau principal solidaire d'une barre transversale en contact avec l'extrémité du pêne du verrou opposé à son extrémité assurant le verrouillage, le coulisseau principal coulissant dans des guides fixés sur la porte et comportant une extrémité coté verrou qui s'engage dans une première gâche fixée dans le mur entourant la porte, l'autre extrémité du coulisseau principal étant prolongée par un coulisseau secondaire relié au coulisseau principal par une articulation et engagé de façon permanente dans une seconde gâche également fixée au mur. Le dispositif est muni d'un ressort qui tend à ramener le coulisseau secondaire et par suite à faire pénétrer le coulisseau principal dans la première gâche lorsque le verrou est mis en position de verrouillage. L'ouverture du verrou repousse la barre transversale, le coulisseau principal et le coulisseau secondaire de sorte que l'extrémité du coulisseau principal sort de la première gâche et que l'articulation se trouve alignée avec les gonds de la porte permettant à celle-ci d'être ouverte.The object of the invention is therefore a protective device for strengthening an opening such as a door of the type comprising a lock. The device comprises at least one main slide secured to a transverse bar in contact with the end of the bolt of the bolt opposite its end ensuring the locking, the main slide sliding in guides fixed on the door and having one end on the bolt side which engages in a first keeper fixed in the wall surrounding the door, the other end of the main slide being extended by a secondary slide connected to the main slide by an articulation and permanently engaged in a second keeper also fixed to the wall. The device is provided with a spring which tends to bring back the secondary slide and consequently to make the main slide penetrate into the first strike when the lock is put in the locked position. The opening of the lock pushes back the transverse bar, the main slide and the secondary slide so that the end of the main slide comes out of the first strike and that the articulation is aligned with the hinges of the door allowing this one to be open.

Les buts, objets et caractéristiques de la présente invention seront mieux compris à la lecture de la description suivante faite en référence aux dessins dans lesquels :

  • la figure 1 représente un premier mode de réalisation du dispositif de renforcement selon l'invention,
  • la figure 2 représente la partie en contact avec le verrou de porte dans une variante du premier mode de réalisation représenté sur la figure 1, et
  • la figure 3 représente un second mode de réalisation du dispositif de renforcement selon l'invention.
The aims, objects and characteristics of the present invention will be better understood on reading the following description made with reference to the drawings in which:
  • FIG. 1 represents a first embodiment of the reinforcement device according to the invention,
  • FIG. 2 represents the part in contact with the door latch in a variant of the first embodiment shown in FIG. 1, and
  • FIG. 3 represents a second embodiment of the reinforcement device according to the invention.

Dans le mode de réalisation représenté sur la figure 1, le dispositif selon l'invention comporte deux barres coulissantes ou coulisseaux principaux 10 et 12 réunis par deux barres transversales 14 et 16. Les deux coulisseaux principaux coulissent dans deux paires de guides, 18 et 20 pour le coulisseau 10, et 22 et 24 pour le coulisseau 12. Les guides 18, 20, 22 et 24 sont fixés sur la porte 26. On doit noter que les guides 18, 20, 22, et 24 pourraient être placés plus près des bords de la porte qu'ils ne le sont sur la figure, ceci étant quasiment indispensable lorsque le dispositif doit être installé sur une porte creuse.In the embodiment shown in FIG. 1, the device according to the invention comprises two sliding bars or main slides 10 and 12 joined by two transverse bars 14 and 16. The two main slides slide in two pairs of guides, 18 and 20 for the slide 10, and 22 and 24 for the slide 12. The guides 18, 20, 22 and 24 are fixed on the door 26. It should be noted that the guides 18, 20, 22, and 24 could be placed closer to the edges of the door than they are in the figure, this being almost essential when the device is to be installed on a hollow door.

Les deux coulisseaux principaux se trouvent vis à vis des gâches 28 et 30 fixées dans le mur du côté ouvrant de la porte, et dans lesquelles ils sont respectivement introduits lorsqu'on ferme le verrou 32, en l'actionnant de l'extérieur à l'aide d'une clé, ou en le tournant de l'intérieur. Le verrou comprend bien entendu, un pêne 34 dont la partie arrière (à gauche sur la figure) est en contact avec une barre horizontale 17 solidaire ou faisant partie intégrante de la barre transversale 16.The two main slides are located opposite the keepers 28 and 30 fixed in the wall on the opening side of the door, and into which they are respectively introduced when the lock 32 is closed, by actuating it from the outside to the using a wrench, or by turning it from the inside. The lock naturally includes a bolt 34, the rear part of which (on the left in the figure) is in contact with a horizontal bar 17 integral with or forming an integral part of the transverse bar 16.

Du côté opposé de la porte qui pivote à l'ouverture sur ses gonds 36 et 38, les deux coulisseaux principaux 10 et 12 sont prolongés par deux coulisseaux secondaires, respectivement 40 et 42, articulés sur les coulisseaux 10 et 12 au moyen des articulations 44 et 46. Les deux coulisseaux secondaires 40 et 42 coulissent respectivement dans les gâches 48 et 50 solidement fixées dans le mur. Comme le montre la coupe partielle de la gâche 50, les extrémités des coulisseaux secondaires prennent appui sur des ressorts de compression, tels que le ressort 52 pour la gâche 50, qui tendent à repousser les coulisseaux vers la partie droite de la porte.On the opposite side of the door which pivots at the opening on its hinges 36 and 38, the two main slides 10 and 12 are extended by two secondary slides, respectively 40 and 42, articulated on the slides 10 and 12 by means of the joints 44 and 46. The two secondary slides 40 and 42 slide respectively in the strikes 48 and 50 solidly fixed in the wall. As shown in the partial section of the keeper 50, the ends of the secondary slides rest on compression springs, such as the spring 52 for the keeper 50, which tend to push the slides towards the right part of the door.

Sur la figure, la porte est représentée en position fermée, c'est à dire que le verrou a été tourné de façon à ce que son pêne 34 soit sorti du côté droit et verrouille la porte 26. Sous l'effet des ressorts se trouvant à l'extrémité des gâches 48 et 50, les deux coulisseaux principaux 10 et 12 sont poussés vers la droite au fur et à mesure que le pêne du verrou est déplacé vers la droite, du fait que la barre horizontale 17 se maintient en contact avec le pêne 34.In the figure, the door is shown in the closed position, that is to say that the bolt has been turned so that its bolt 34 has come out on the right side and locks the door 26. Under the effect of the springs located at the ends of the strikes 48 and 50, the two slides main 10 and 12 are pushed to the right as the bolt of the bolt is moved to the right, because the horizontal bar 17 remains in contact with the bolt 34.

Dans la position fermée de la porte, on voit donc que les deux coulisseaux principaux 10 et 12 sont engagés dans leur gâche respective 28 ou 30, alors que les extrémités des deux coulisseaux secondaires 40 et 42 se trouvent en partie dans leur gâche respective 48 ou 50. Par conséquent, la porte fermée dispose de 4 points forts de fermeture en plus du verrou.In the closed position of the door, we therefore see that the two main slides 10 and 12 are engaged in their respective keeper 28 or 30, while the ends of the two secondary slides 40 and 42 are partly in their respective keeper 48 or 50. Consequently, the closed door has 4 closing strengths in addition to the latch.

Pour ouvrir la porte, on tourne le verrou 32 de sorte que son pêne 34 pousse vers la gauche la barre transversale 16, entraînant du même coup l'ensemble des deux coulisseaux principaux 10 et des deux coulisseaux secondaires 40 et 42 qui compriment les ressorts se trouvant dans les gâches 48 et 50 au fur et à mesure que le verrou est tourné.To open the door, the latch 32 is turned so that its bolt 34 pushes the transverse bar 16 to the left, at the same time driving all of the two main slides 10 and the two secondary slides 40 and 42 which compress the springs found in strikes 48 and 50 as the bolt is turned.

Lorsque le verrou est complètement ouvert, les articulations 44 et 46 se trouvent dans l'alignement des gonds 36 et 38 de la porte 26. Par conséquent, l'ouverture de la porte peut s'effectuer aisément en pivotant autour de ses gonds pendant que les deux coulisseaux 10 et 12 pivotent autour de leurs articulations respectives 44 et 46. On notera que les articulations 44 et 46 peuvent prendre différents aspects, l'essentiel étant de permettre un pivotement de la porte d'environ 150°.When the lock is fully open, the joints 44 and 46 are in alignment with the hinges 36 and 38 of the door 26. Consequently, the opening of the door can be carried out easily by pivoting around its hinges while the two slides 10 and 12 pivot around their respective joints 44 and 46. It will be noted that the joints 44 and 46 can take different aspects, the main thing being to allow the door to pivot about 150 °.

Le dispositif de renforcement qui vient d'être décrit en référence à la figure 1 peut être facilement installé sur une porte comportant déjà un verrou. Comme il existe deux largeurs de portes standardisées 83 cm et 93 cm, il suffit de prévoir un dispositif dont la longueur des coulisseaux principaux est adaptée au premier type de porte et un dispositif dont la longueur des coulisseaux principaux est adaptée au second type de porte. Par contre, quelle que soit le type de porte utilisé, le verrou déjà installé peut avoir des dimensions très différentes selon la modèle utilisé. C'est pourquoi pour l'un ou l'autre modèle de dispositif selon l'invention, la barre horizontale devra avoir une longueur ayant la plus grande valeur possible correspondant à un verrou de la plus petite largeur possible. Cette barre sera alors coupée de façon à se trouver en contact permanent avec le verrou lorsque le dispositif sera posé correctement sur la porte. La longueur à couper sera déterminée en ajustant le dispositif sur la porte lorsque le verrou est ouvert et la porte également de façon à tenir compte du déport dû aux gonds lorsque la porte est ouverte.The reinforcing device which has just been described with reference to Figure 1 can be easily installed on a door already having a lock. As there are two widths of standardized doors 83 cm and 93 cm, it suffices to provide a device whose length of the main slides is adapted to the first type of door and a device whose length of the main slides is adapted to the second type of door. On the other hand, whatever the type of door used, the lock already installed can have very different dimensions depending on the model used. This is why for either model of device according to the invention, the horizontal bar must have a length having the greatest possible value corresponding to a latch of the smallest possible width. This bar will then be cut so as to be in permanent contact with the lock when the device is correctly placed on the door. The length to be cut will be determined by adjusting the device on the door when the lock is open and the door also so as to take into account the offset due to the hinges when the door is open.

Cependant, il est possible de prévoir une variante du premier mode de réalisation dans lequel il n'est pas nécessaire de couper une barre. Dans cette variante dont seule la partie modifiée a été représentée sur la figure 2, il n'existe pas de barre horizontale comme dans le mode de réalisation de la figure 1. Mais la barre transversale 16 solidaire des coulisseaux principaux 10 et 12 a été remplacée par une barre transversale mobile 60. Cette barre 60 comporte des évidements 62 et 64 à ses extrémités permettant le passage coulissant des coulisseaux principaux 10 et 12 respectivement. Lors de l'installation du dispositif sur la porte, on commence par ajuster correctement les coulisseaux principaux et secondaires sur la porte en position ouverte. Puis on fait coulisser la barre mobile 60 de façon à l'amener en contact avec le pêne du verrou en position déverrouillée telle qu'illustré sur la figure 2. Enfin, il suffit de serrer fortement les vis 66 et 68 contre les coulisseaux principaux 10 et 12 respectivement pour rendre la barre transversale 60 solidaire desdits coulisseaux.However, it is possible to provide a variant of the first embodiment in which it is not necessary to cut a bar. In this variant, of which only the modified part has been shown in FIG. 2, there is no horizontal bar as in the embodiment of FIG. 1. But the transverse bar 16 secured to the main slides 10 and 12 has been replaced by a movable transverse bar 60. This bar 60 has recesses 62 and 64 at its ends allowing the sliding passage of the main slides 10 and 12 respectively. When installing the device on the door, we start by correctly adjusting the main and secondary slides on the door in the open position. Then the movable bar 60 is made to slide so as to bring it into contact with the bolt of the lock in the unlocked position as illustrated in FIG. 2. Finally, it suffices to tighten the screws 66 and 68 firmly against the main slides 10 and 12 respectively to make the transverse bar 60 integral with said slides.

Les coulisseaux principaux et secondaires peuvent être réalisés en toute matière, en métal de préférence, l'acier étant préféré pour sa grande solidité. De façon à pouvoir faire coulisser les coulisseaux dans leurs guides, et ceci en exerçant un effort raisonnable lors de la manipulation du verrou, il est judicieux de prévoir des billes de roulement dans chacun des guides 18, 20, 22 et 24 sur lesquelles se déplacent les coulisseaux lors de l'ouverture de la porte.The main and secondary slides can be made of any material, preferably of metal, steel being preferred for its great solidity. In order to be able to slide the slides in their guides, and this by exerting a reasonable effort when handling the lock, it is advisable to provide rolling balls in each of the guides 18, 20, 22 and 24 on which move. the slides when the door is opened.

Bien que le dispositif représenté sur la figure 1 comporte 2 coulisseaux, on pourrait envisager un seul coulisseau muni d'une barre transversale sur laquelle s'appuierait le pêne du verrou, ce qui procurerait deux points d'ancrage seulement de part et d'autre de la porte. De la même façon, il est possible de prévoir 3 ( ou plus) coulisseaux, toujours manoeuvrés par un seul verrou.Although the device shown in Figure 1 has 2 slides, one could consider a single slide with a cross bar on which the bolt of the bolt would rest, which would provide only two anchor points on either side Door. In the same way, it is possible to provide 3 (or more) sliders, always operated by a single lock.

Que ce soit avec un, deux, trois (ou plus) coulisseaux, le dispositif de l'invention présente la particularité de se déplacer par rapport à la porte, uniquement par translation, lors de l'ouverture de la porte, sans faire appel à aucune pièce tournante, évitant ainsi toute difficulté d'ouverture ainsi que la fragilité inhérente aux dispositifs antérieurs comportants des pièces tournantes.Whether with one, two, three (or more) slides, the device of the invention has the particularity of moving relative to the door, only by translation, when the door is opened, without using no rotating part, thus avoiding any difficulty in opening as well as the inherent fragility of previous devices comprising rotating parts.

Bien entendu, la disposition des murs de chaque côté de la porte ne permet pas toujours d'installer les gâches de la façon représentée sur la figure. C'est pourquoi un second mode de réalisation permet de pouvoir installer le dispositif selon l'invention même si on ne dispose pas d'une longueur de mur suffisante permettant d'installer des gâches comportant des ressorts de compression comme c'est le cas dans le mode de réalisation de la figure 1. Dans ce second mode de réalisation illustré sur la figure 3, le dispositif de renforcement est fixé préalablement sur une plaque de métal, par exemple en acier. Cette plaque d'une épaisseur d'environ 0,5 mm peut être soit fixée sur le panneau de la porte, soit au moyen de pattes qui se vissent dans les champs de la porte et maintiennent solidement la plaque 70 solidaire de la porte. De façon à ne pas avoir à ôter ou modifier le verrou, la plaque comporte un évidement 72 de forme rectangulaire sur le côté où se trouve le verrou et de dimensions telles que cet évidement puisse contenir n'importe quel verrou existant déjà placé sur la porte.Of course, the arrangement of the walls on each side of the door does not always allow the strikes to be installed as shown in the figure. This is why a second embodiment makes it possible to install the device according to the invention even if there is not a sufficient wall length allowing the installation of strikes comprising compression springs as is the case in the embodiment of Figure 1. In this second embodiment illustrated in Figure 3, the reinforcing device is fixed beforehand on a metal plate, for example steel. This plate with a thickness of about 0.5 mm can be either fixed to the door panel, or by means of lugs which are screwed into the fields of the door and firmly hold the plate 70 integral with the door. So as not to have to remove or modify the lock, the plate has a recess 72 of rectangular shape on the side where the lock is located and of dimensions such that this recess can contain any existing lock already placed on the door .

Comme illustré sur la figure 3, la barre transversale 16, qui pourrait d'ailleurs être remplacée par la barre transversale mobile 60 de la figure 2, est maintenue vers la droite par deux ressorts 74 et 76 fixés d'une part à la barre et d'autre par à la plaque 70 par des points d'ancrage 78 et 80. Lorsque le verrou est mis dans la position de déverrouillage, son pêne 34 en contact avec la barre horizontale 17 pousse celle-ci et donc les coulisseaux 10 et 12 vers la gauche. Les coulisseaux secondaires 40 et 42 sont également poussés vers la gauche en coulissant dans des gâches 82 et 84. Du fait que ces dernières ne comportent pas des ressorts de compression comme dans le mode de réalisation illustré sur la figure 1, leur installation ne nécessite pas une grande longueur de mur et la largeur du chambranle de la porte est suffisant pour les installer.As illustrated in Figure 3, the crossbar 16, which could also be replaced by the movable crossbar 60 of Figure 2, is held towards the straight by two springs 74 and 76 fixed on the one hand to the bar and on the other by to the plate 70 by anchor points 78 and 80. When the bolt is put in the unlocking position, its bolt 34 in contact with the horizontal bar 17 pushes it and therefore the slides 10 and 12 to the left. The secondary slides 40 and 42 are also pushed to the left by sliding in strikes 82 and 84. Because the latter do not include compression springs as in the embodiment illustrated in FIG. 1, their installation does not require a large wall length and the width of the door frame is sufficient to install them.

Le déverrouillage du verrou 32 a pour effet de tendre les ressorts 74 et 76 qui exercent ainsi une force de traction ramenant les coulisseaux vers la droite lorsque le verrou est de nouveau mis en position de verrouillage.Unlocking the lock 32 has the effect of tensioning the springs 74 and 76 which thus exert a tensile force bringing the sliders to the right when the lock is again put in the locked position.

On voit donc à la lecture de la description précédente que, quel que soit le mode de réalisation du dispositif selon l'invention, on peut installer ce dispositif sur une porte quelconque disposant déjà de son verrou, ce qui permet d'éviter d'engager des frais exorbitants comme c'est le cas avec certains dispositifs qui nécessitent de refaire la porte ou de retirer les verrous existants. Bien sûr, l'installation des gâches peut nécessiter des adaptations différentes de ce qui est montré sur la figure, selon la disposition des murs.It is therefore seen on reading the preceding description that, whatever the embodiment of the device according to the invention, this device can be installed on any door already having its lock, which makes it possible to avoid engaging exorbitant costs as is the case with certain devices that require redoing the door or removing existing locks. Of course, installing the strikes may require different adaptations from what is shown in the figure, depending on the layout of the walls.

Bien que le dispositif de l'invention ait été représenté montré sur une porte, il est évident qu'il pourrait être installé sur une fenêtre ou tout autre ouverture. De même, il est possible d'installer deux dispositifs identiques sur la même porte si l'on dispose déjà de deux verrous séparés.Although the device of the invention has been shown shown on a door, it is obvious that it could be installed on a window or any other opening. Likewise, it is possible to install two identical devices on the same door if two separate locks are already available.
