Description

L'invention concerne les serrures comportant au moins un bloc de sûreté et se montant soit dans une mortaise de la porte, soit en applique.The invention relates to locks comprising at least one block of safety and being mounted either in a mortise of the door, or in wall.

Elle vise plus spécialement, mais non exclusivement, les serrures équipées d'un bloc de sûreté dit Européen et composées de deux cylindres coaxiaux disposés dans des corps qui, espacés pour laisser passer un paneton ou une lanterne, sont reliés l'un à l'autre par un pontet inférieur. Dans les blocs de sûreté actuels, ce pontet est traversé par un trou taraudé destiné à recevoir l'extrémité d'une vis de maintien, disposée dans un logement perpendiculaire au champ de la porte et débouchant de celui-ci et dans le logement pour le bloc de sûreté.More specifically, but not exclusively, it relates to locks equipped with a so-called European safety block and composed of two cylinders coaxial arranged in bodies which, spaced to let pass a paneton or a lantern, are connected to each other by a lower trigger guard. In the blocks safety bridge, this trigger guard is crossed by a tapped hole intended to receive the end of a retaining screw, placed in a perpendicular housing in the field of the door and emerging from it and in the housing for the safety block.

Il est bien connu que ce trou taraudé, qui est réalisé dans la zone la moins épaisse du corps du bloc, fragilise ce bloc au niveau du pontet.It is well known that this tapped hole, which is made in the area the thinner of the block body, weakens this block at the trigger guard.

Lorsque la serrure est montée sur une porte, qu'elle soit dans une mortaise ou en applique, le bloc de sûreté est soit en saillie, soit en affleurement de la face extérieure.When the lock is mounted on a door, whether it is in a mortise or surface, the safety block is either projecting or flush with the outside.

Lorsqu'il est en saillie, une frappe violente sur lui, exercée transversalement à lui, peut entraíner la rupture du pontet de liaison et permettre de continuer l'effraction.When it protrudes, a violent strike on it, exerted transversely to it, can cause the linkage to break and allow the break-in to continue.

Lorsque le bloc de sûreté affleure, il reste sensible à une frappe axiale pouvant l'enfoncer ou à un effort d'arrachement, ces deux manoeuvres ayant pour but de provoquer la rupture du pontet pour poursuivre l'effraction.When the safety block is flush, it remains sensitive to a knock axial can push it in or a tearing force, these two maneuvers intended to cause the trigger guard to break to continue the break-in.

La présente invention a pour objet de fournir une serrure avec bloc de sûreté remédiant à cela et présentant une résistance à l'effraction améliorée.The object of the present invention is to provide a lock with a block. security remedying this and having burglary resistance improved.

A cet effet, dans la serrure anti effraction selon l'invention, le corps du bloc de sûreté disposé sur l'extérieur de l'ouvrant est entouré, sur tout ou partie de sa longueur saillant du boítier de serrure, par un anneau bouclier épousant le profil extérieur de ce corps et lié à lui par au moins un organe de liaison, tel que goupille ou vis sans tête, traversant cet anneau et pénétrant dans un logement ménagé dans le corps, au-dessous du rotor du cylindre, tandis que la fixation sur la porte de l'ensemble bloc de sûreté-bouclier est assurée par au moins une vis, engagée de l'intérieur de la porte, traversant la porte et le boítier par des logements cylindriques et se vissant dans un alésage taraudé, ménagé dans le bouclier et débouchant de la face postérieure de celui-ci. To this end, in the burglar-resistant lock according to the invention, the body the safety block placed on the outside of the opening is surrounded, on all or part of its protruding length from the lock housing, by a shield ring conforming to the external profile of this body and linked to it by at least one organ of connection, such as a pin or grub screw, passing through this ring and penetrating in a housing in the body, below the cylinder rotor, while the fixing on the door of the safety block-shield assembly is ensured by at least one screw, engaged from the inside of the door, crossing the door and housing by cylindrical housings and screwing into a bore tapped, formed in the shield and emerging from the rear face of this one.

Avec cet agencement, la partie du bloc de sûreté extérieur est enveloppée par un anneau bouclier qui le renforce et le rend moins sensible à une frappe violente. Par ailleurs, la fixation de l'ensemble par au moins une vis plaquant l'anneau bouclier contre une surface plane du boítier, ou de la porte, réduit les risques d'enfoncement du corps du cylindre. Cette fixation présente aussi l'avantage de permettre la suppression du trou taraudé ménagé dans le pontet reliant la partie extérieure à la partie intérieure du bloc de sûreté et, en conséquence, permet d'augmenter la résistance de ce pontet.With this arrangement, the part of the exterior safety block is wrapped by a shield ring which strengthens it and makes it less sensitive to a violent strike. Furthermore, the fixing of the assembly by at least one screw pressing the shield ring against a flat surface of the case, or of the door, reduces the risk of the cylinder body sinking. This fixation presents also the advantage of allowing the removal of the tapped hole formed in the trigger guard connecting the external part to the internal part of the safety block and, in Consequently, increases the resistance of this trigger guard.

Dans une forme d'exécution, la vis sans tête, fixant le bouclier sur le corps du bloc de sûreté, est disposée dans un alésage taraudé ménagé transversalement dans l'anneau et est protégée par un insert en matériau à haute résistance, pénétrant transversalement dans l'alésage taraudé pour la vis et disposé dans un logement allant de la face arrière du bouclier à cet alésage taraudé.In one embodiment, the grub screw, fixing the shield on the body of the safety block, is arranged in a tapped bore transversely in the ring and is protected by an insert made of material high resistance, penetrating transversely into the threaded bore for the screw and arranged in a housing going from the rear face of the shield to this threaded bore.

Cet aménagement, qui est appliqué lorsque l'anneau bouclier n'est pas encastré dans la porte, s'oppose à tout accès à la vis assurant sa fixation sur le corps de cylindre.This arrangement, which is applied when the shield ring is not not embedded in the door, prevents any access to the screw ensuring its fixing on the cylinder body.

Pour satisfaire aux besoins de sécurité des chantiers utilisant des blocs de sûreté spécifiques, par une combinaison différente de celle des blocs posés ultérieurement, et pour permettre la fixation temporaire de ces blocs alors que les dits blocs et serrures sont conformes à l'invention, ne sont pas fixables par une vis perpendiculaire au champs de l'ouvrant et ne peuvent être fixés par leur bouclier, non nécessaire pour un chantier, dans une forme d'exécution de l'invention, le boítier de serrure comporte au moins un logement qui, disposé parallèlement à la direction d'engagement du bloc de sûreté dans ce boítier et près de l'ouverture prévue pour le passage du bloc, forme palier pour la tige cylindrique d'un dispositif de calage temporaire, dispositif dont la tête de blocage est au moins munie d'une portée excentrée apte, par rotation, à occuper soit une position de dégagement, dans laquelle elle est hors de la trajectoire d'engagement du bloc de sûreté dans le boítier, soit une position de calage, dans laquelle elle est en appui contre le corps de ce bloc de sûreté et assure son calage contre le boítier.To meet the safety needs of construction sites using specific safety blocks, by a different combination from that of the blocks installed later, and to allow temporary fixing of these blocks while the said blocks and locks are in accordance with the invention, are not fixed by a screw perpendicular to the opening field and cannot be fixed by their shield, not necessary for a site, in a form of the invention, the lock housing includes at least one housing which, arranged parallel to the direction of engagement of the safety block in this housing and near the opening provided for the passage of the block, bearing shape for the cylindrical rod of a temporary wedging device, device the blocking head is at least provided with a suitable eccentric bearing, by rotation, to occupy either a release position, in which it is out of the path of engagement of the safety block in the case, i.e. stalling position, in which it bears against the body of this safety block and secures it against the housing.

Ainsi, lors de l'organisation d'un chantier, la fixation de chaque bloc est assurée par le seul dispositif de calage, dont la tête est pivotée par rapport au boítier et de manière que sa portée excentrée vienne au contact du corps du bloc de sûreté et plaque ce bloc contre les bords des lumières ménagées dans le boítier et dans son couvercle pour le passage de ce bloc.Thus, during the organization of a site, the fixing of each block is ensured by the sole wedging device, the head of which is pivoted relative to the housing and so that its eccentric reach comes into contact with the body of the safety block and plate this block against the edges of the lights in the housing and in its cover for the passage of this block.

    • A la figure 1, la référence numérique 2 désigne de manière générale le boítier d'une serrure encastrable dans la mortaise d'un ouvrant et comportant un pêne demi tour 3 et un pêne dormant 4, actionnable par le paneton 5 d'un bloc de sûreté 6. Le bloc de sûreté représenté est de type européen et est composé d'un corps 7 en deux parties 7a, 7b reliées par un pontet 8, chaque partie du corps formant une enveloppe pour un cylindre 9a, 9b actionnable par une clé.In FIG. 1, the reference numeral 2 designates so general the case of a lock built into the mortise of an opening and comprising a latch bolt 3 and a deadbolt 4, actuable by the paneton 5 of a safety block 6. The safety block shown is of the type European and is composed of a body 7 in two parts 7a, 7b connected by a trigger guard 8, each part of the body forming an envelope for a cylinder 9a, 9b actuated by a key.

    De façon connue, le bloc de sûreté 6 est mis en place dans la porte après que le boítier de serrure ait été engagé dans la mortaise de cette porte. Cette mise en place est réalisée par engagement transversal dans des logements ménagés dans la porte et dans le boítier et ayant la forme de ceux représentés en 10 à la figure 1. In known manner, the safety block 6 is placed in the door after the lock case has been engaged in the mortise of this door. This implementation is carried out by transversal engagement in housings in the door and in the housing and having the shape of those shown at 10 in Figure 1.

    Selon l'invention, la partie 7a du bloc de sûreté, qui contient le cylindre 9a accessible de l'extérieur par une clé, est entourée par un anneau bouclier 12 dont le logement interne 11 épouse son profil extérieur. Le profil extérieur de cet anneau est oblong, comme représenté aux figures 1 et 2, circulaire ou de toute autre forme. Cet anneau-bouclier 12 est réalisé dans un matériau plus dur que celui constituant le corps 7a, 7b et, par exemple alliage métallique, matériaux composites. Il a une épaisseur qui dépend du type de serrure et qui peut être égale, ou inférieure, à la longueur de la partie de corps 7a sur laquelle il se monte.According to the invention, part 7a of the security block, which contains the cylinder 9a accessible from the outside by a key, is surrounded by a ring shield 12 whose internal housing 11 matches its external profile. The profile outside of this ring is oblong, as shown in FIGS. 1 and 2, circular or any other shape. This shield ring 12 is produced in a harder material than that constituting the body 7a, 7b and, for example alloy metallic, composite materials. It has a thickness which depends on the type of lock and which may be equal to, or less than, the length of the body part 7a on which it is mounted.

    Pour sa liaison avec ce corps 7a, l'anneau bouclier 12 comprend un alésage taraudé 13 qui, dans la forme d'exécution représentée figure 2, comporte un axe longitudinal horizontal disposé perpendiculairement à l'axe longitudinal du bloc de sûreté 6 et sensiblement à mi épaisseur de l'anneau 12. Cet alésage taraudé 13 est destiné à recevoir une vis sans tête 14 dont l'extrémité antérieure, épaulée ou non, est destinée à pénétrer dans un logement lisse 15, ménagé dans la partie 7a du corps et au-dessous du cylindre 9a correspondant.For its connection with this body 7a, the shield ring 12 comprises a threaded bore 13 which, in the embodiment shown in FIG. 2, has a horizontal longitudinal axis arranged perpendicular to the axis longitudinal of the safety block 6 and substantially mid-thickness of the ring 12. This threaded bore 13 is intended to receive a grub screw 14 of which the anterior end, shouldered or not, is intended to penetrate a smooth housing 15, formed in part 7a of the body and below the corresponding cylinder 9a.

    Comme le montre la figure 2, le bouclier 12 est également traversé dans son épaisseur par un alésage borgne 16, débouchant de la face postérieure 12a du bouclier et allant de cette face jusqu'à l'alésage taraudé 13. Cet alésage 16 est destiné à recevoir une goupille cylindrique anti effraction 17, en matériau à haute résistance. La figure 3 montre que, lorsque cette goupille 17 est mise en place dans ce logement 16 et pénètre sensiblement diamétralement dans le logement 13 pour la vis sans tête 14, elle empêche d'accéder à l'empreinte 14a ménagée dans cette vis et rend difficile sa destruction par perçage.As shown in Figure 2, the shield 12 is also crossed in its thickness by a blind bore 16, opening from the face posterior 12a of the shield and going from this face to the threaded bore 13. This bore 16 is intended to receive a burglar-resistant cylindrical pin 17, made of high resistance material. Figure 3 shows that when this pin 17 is placed in this housing 16 and penetrates substantially diametrically in the housing 13 for the grub screw 14, it prevents access the imprint 14a formed in this screw and makes it difficult to destruction by drilling.

    Dans une variante, non représentée, cette goupille est remplacée par un insert, par exemple par une plaquette en matériau résistant, métallique, composite ou autre. Cet insert est introduit dans un logement similaire à celui 16 et dont la section transversale est identique à la sienne.In a variant, not shown, this pin is replaced by an insert, for example by a plate of resistant, metallic material, composite or otherwise. This insert is inserted into a housing similar to that 16 and whose cross section is identical to hers.

    Dans la forme d'exécution représentée l'anneau bouclier 12 est solidaire d'une gouttière 18 qui fait saillie de sa face postérieure 12a et est destinée à venir au dessous et au contact avec le pontet 8, reliant les deux parties 7a et 7b du corps du bloc de sûreté. Comme montré figure 1, au moins le couvercle 2a du boítier 2 comporte une découpe 21 permettant l'engagement de la gouttière 18 dans le boítier. In the embodiment shown the shield ring 12 is integral with a gutter 18 which projects from its rear face 12a and is intended to come below and in contact with trigger guard 8, connecting the two parts 7a and 7b of the body of the safety block. As shown in Figure 1, at least the cover 2a of the housing 2 includes a cutout 21 allowing the engagement of the gutter 18 in the housing.

    Enfin, l'anneau bouclier 12 comporte au moins un, et de préférence deux, trous taraudés 19 destinés à coopérer avec une vis de fixation 20. Chacun de ces trous taraudés est borgne et débouche de la face postérieure 12a du bouclier. Les deux trous sont disposés de part et d'autre du plan médian vertical de ce bouclier et, dans la forme d'exécution représentée, au-dessous des parties du corps contenant les cylindres.Finally, the shield ring 12 comprises at least one, and preferably two, threaded holes 19 intended to cooperate with a fixing screw 20. Each of these tapped holes is blind and opens from the rear side 12a of the shield. The two holes are arranged on either side of the plane vertical median of this shield and, in the embodiment shown, below body parts containing the cylinders.

    Lorsque le boítier de serrure 2 est mis en place dans sa mortaise, l'ensemble bloc de sûreté 6 - anneau bouclier 12 est mis en place, puis est fixé au moyen des deux vis 20 qui sont engagées par l'intérieur de la porte. Chacune d'elles traverse successivement un logement ménagé dans la porte, un logement 25 ménagé dans le boítier 2 et son couvercle 2a, et, et enfin un logement ménagé dans la porte, avant de se visser dans l'alésage taraudé 19.When the lock box 2 is placed in its mortise, the safety block 6 - shield ring 12 assembly is put in place, then is fixed by means of the two screws 20 which are engaged by the interior of the door. Each of them successively passes through a housing provided in the door, a housing 25 formed in the housing 2 and its cover 2a, and, finally housing in the door, before screwing into the threaded bore 19.

    Pour éviter que, sous l'action du serrage de ces deux vis 20, les deux parois latérales du boítier 2 soient déformées, une entretoise 22 est disposée dans ce boítier, comme montré à la figure 1. Cette entretoise, métallique ou en matière plastique, comporte des passages 23 pour les vis 20, mais aussi une rainure 24 de réception de la gouttière 18 de renforcement du bloc de sûreté.To avoid that, under the action of tightening these two screws 20, the two side walls of the housing 2 are deformed, a spacer 22 is arranged in this case, as shown in Figure 1. This spacer, metallic or plastic, has passages 23 for the screws 20, but also a groove 24 for receiving the gutter 18 for strengthening the safety block.

    L'anneau bouclier peut, selon l'épaisseur de la porte, prendre appui directement sur le boítier, prendre appui sur le fond d'un logement réalisé dans la porte, et, dans ce cas, être affleurant avec la face avant de la porte ou déborder de la porte.The shield ring can, depending on the thickness of the door, be supported directly on the housing, take support on the bottom of a housing made in the door, and, in this case, be flush with the front face of the door or overflow from the door.

    La figure 4 montre un bouclier qui est plus long que celui représenté aux figures 1 et 2 et qui est destiné, par sa face postérieure 12a, à venir en appui contre le boítier de serrure, par son corps à être partiellement noyé dans l'épaisseur de la porte, et par sa partie avant à former une saillie par rapport à la face avant de la porte.Figure 4 shows a shield that is longer than that shown in Figures 1 and 2 and which is intended, by its rear face 12a, to come to rest against the lock case, by its body to be partially embedded in the thickness of the door, and by its front part to form a projection by compared to the front of the door.

    Le bloc de sûreté équipé d'un tel anneau bouclier est particulièrement résistant aux tentatives d'effraction par frappe violente, quelle que soit la direction de ces frappes, et, par sa gouttière, améliore la résistance du pontet 8, qui est déjà améliorée par la suppression du trou taraudé le fragilisant dans les blocs de sûreté actuels. En fin d'assemblage, le bouclier, le bloc de sûreté, et le boítier de serrure forment un ensemble plus rigide et plus résistant à l'extraction et à l'enfoncement, ce qui améliore la résistance à l'effraction. The safety block fitted with such a shield ring is particularly resistant to violent break-in attempts, whatever the direction of these strikes, and, by its gutter, improves the resistance of the trigger guard 8, which is already improved by the elimination of the tapped hole the weakening in current safety blocks. At the end of assembly, the shield, the safety block, and the lock box form a more rigid and more resistant to extraction and sinking, which improves resistance to burglary.

    Dans une variante de réalisation, non représentée, la vis sans tête 14 se visse dans un alésage taraudé 13 qui débouche de la face arrière 12a de l'anneau 12 et dont l'axe longitudinal est oblique par rapport à l'axe longitudinal du corps. Bien entendu, l'axe du logement 15 recevant la vis 14 dans le corps est également oblique puisque coaxial à celui de l'alésage 13.In an alternative embodiment, not shown, the grub screw 14 is screwed into a threaded bore 13 which opens from the rear face 12a of the ring 12 and whose longitudinal axis is oblique to the longitudinal axis from the body. Of course, the axis of the housing 15 receiving the screw 14 in the body is also oblique since it is coaxial with that of bore 13.

    Cette disposition évite de prévoir un insert de sécurité 17 puisque l'accès à la vis 14 est caché.This arrangement avoids providing a security insert 17 since access to screw 14 is hidden.

    Dans une autre variante de réalisation, non représentée, la vis 14 est remplacée par une goupille qui, cylindrique, conique ou expansible, est engagée de force dans l'alésage 13, alors non taraudé, et dans l'alésage lisse 15. Les axes longitudinaux de ces deux alésages sont soit radiaux, comme montré aux figures 2 et 3, soit obliques, comme indiqué ci-dessus. Dans ce cas et de préférence, l'alésage ménagé dans le bouclier 12 débouche de la face postérieure 12a de celui-ci.In another alternative embodiment, not shown, the screw 14 is replaced by a pin which, cylindrical, conical or expandable, is forcibly engaged in bore 13, then not tapped, and in smooth bore 15. The longitudinal axes of these two bores are either radial, as shown in Figures 2 and 3, either oblique, as shown above. In that case and preferably, the bore in the shield 12 opens from the face posterior 12a thereof.

    La forme d'exécution représentée aux figures 5 à 9 est relative à un dispositif de calage 26 permettant de bloquer temporairement le bloc de sûreté 6, par exemple lors d'un chantier dont la sécurité est assurée par des blocs de sûreté selon l'invention, sans bouclier 12 et sans possibilité de fixation par la traditionnelle vis traversant perpendiculairement le champ de l'ouvrant. Ce dispositif de est composé d'une tige cylindrique 27, solidaire d'une tête 28, également cylindrique mais dont l'axe longitudinal est excentré d'une valeur E par rapport à l'axe longitudinal de la tige, comme montré à la figure 7. Cette tête comporte une empreinte 29 pour un outil, et par exemple, une empreinte hexagonale et, dans sa partie la plus excentrée, un méplat 30. Dans une variante de réalisation, non représentée, la tête 28 est en forme en came dont la partie la plus éloignée radialement de l'axe de la tige 27 est disposée à la place du méplat 30.The embodiment shown in Figures 5 to 9 relates to a wedging device 26 for temporarily blocking the safety block 6, for example during a site where security is ensured by blocks of safety according to the invention, without shield 12 and without possibility of fixing by the traditional screw perpendicularly crossing the opening field. This device is composed of a cylindrical rod 27, integral with a head 28, also cylindrical but whose longitudinal axis is offset by an E value relative to the longitudinal axis of the rod, as shown in Figure 7. This head has an imprint 29 for a tool, and for example, an imprint hexagonal and, in its most eccentric part, a flat 30. In a variant, not shown, the head 28 is cam-shaped, the part radially furthest from the axis of the rod 27 is disposed at the place of the flat 30.

    Avec cet agencement, lorsque le boítier est monté sur un dormant et que le bloc de sûreté 6 est engagé dans les logements 10 de la serrure, le blocage temporaire de ce bloc de sûreté est assuré, sur la partie intérieure de l'ouvrant, par l'engagement de la tige 27 dans un palier du boítier et par rotation du dispositif. Dans la forme de réalisation représentée le palier d'accueil de la tige 27 est constitué par l'un des logements 25 prévus dans le boítier et le couvercle pour le passage des vis 20 de fixation du bouclier. Dans une variante, non représentée, le palier est formé par un logement différent de ceux 25 du boítier 2. With this arrangement, when the housing is mounted on a frame and that the safety block 6 is engaged in the housings 10 of the lock, the temporary blocking of this safety block is ensured, on the inner part of the opening, by the engagement of the rod 27 in a bearing of the housing and by rotation of the device. In the embodiment shown the reception landing of the rod 27 is constituted by one of the housings 25 provided in the housing and the cover for the passage of the shield fixing screws 20. In variant, not shown, the bearing is formed by a housing different from those 25 of housing 2.

    La figure 9 montre que la tige 27 est d'abord positionnée de manière que son méplat 30 soit à l'opposé du logement 10 pour le passage du bloc de sûreté et soit dans une position dite d'engagement, permettant d'ajuster la position longitudinale du bloc de sûreté 6 dans la serrure. Ensuite, et comme montré à la figure 8, la tête 28 est entraínée en rotation, par exemple dans le sens de la flèche 31 de figure 8, de manière que son méplat 30 vienne au contact du corps du bloc 6. Dans cette position, la tête 28 plaque le bloc de sûreté contre les bords 10a des logements10 et assure ainsi le calage du bloc dans la serrure.Figure 9 shows that the rod 27 is first positioned so that its flat 30 is opposite the housing 10 for the passage of the safety block and either in a position called engagement, allowing to adjust the longitudinal position of the safety block 6 in the lock. Then, and like shown in Figure 8, the head 28 is rotated, for example in the direction of the arrow 31 in FIG. 8, so that its flat 30 comes to the contact of the body of the block 6. In this position, the head 28 presses the block of safety against the edges 10a of the housings10 and thus secures the block in the lock.

    Dans une autre forme d'exécution, non représentée, pouvant être utilisée pour assurer la fixation, temporaire ou permanente d'une serrure, à plaquer ou à larder,avec bloc de sûreté, le dispositif de calage 26 est disposé en totalité dans le boítier de la serrure. Dans ce cas, la tige cylindrique 27 est monté libre en rotation dans des paliers ménagés dans le coffre et ce dernier ou son couvercle possède une ouverture permettant d'accéder au moyen 29 d'entraínement en rotation ménagé dans la tête 28. Cet aménagement impose de réaliser, dans la porte, un trou pour accéder au moyen d'entraínement 29 de la tête, mais ce trou peut être aisément occulté, d'un coté, par une plaque de propreté, solidaire ou non de la poignée d'actionnement du pêne demi tour, et, de l'autre coté, par l'anneau-bouclier 12.In another embodiment, not shown, which can be used to secure a temporary or permanent lock, to tackle or lard, with safety block, the wedging device 26 is arranged entirely in the lock housing. In this case, the cylindrical rod 27 is freely mounted in rotation in bearings provided in the boot and the latter or its cover has an opening allowing access to the means 29 rotational drive in the head 28. This arrangement requires to make a hole in the door to access the drive means 29 of the head, but this hole can be easily concealed, on one side, by a plate of cleanliness, whether or not integral with the handle for actuating the latch bolt, and, on the other side, by the shield ring 12.

    Quelle que soit sa forme de réalisation, le dispositif de calage 26 permet, de manière simple et rapide, d'assurer la liaison d'un bloc de sûreté avec le boítier d'une serrure pour obtenir une fixation temporaire ou permanente.Whatever its embodiment, the wedging device 26 allows, in a simple and fast way, to ensure the connection of a safety block with the housing of a lock to obtain a temporary fixing or permed.

    La serrure qui vient d'être décrite comporte un bloc de sûreté avec deux cylindres, mais il est évident que l'invention s'applique également à un bloc avec un cylindre extérieur et un bouton, ou autre moyen d'actionnement intérieur.The lock which has just been described comprises a safety block with two cylinders, but it is obvious that the invention also applies to a block with an external cylinder and a button, or other actuating means inside.
