Description
L'invention concerne un dispositif de protection pour boîtier servant au logement d'un mécanisme de commande d'une ferrure de verrouillage encastrée dans un ouvrant et comprenant un élément à clé, du type barillet, s'étendant au travers de plaques de propreté disposées du côté interne et externe de l'ouvrant, ce dispositif comportant au moins une plaque anti-perçage disposée du côté externe par rapport au boîtier et rendu solidaire de l'ouvrant à l'aide d'organes de fixation accessibles du côté interne de ce dernier, cette plaque anti-perçage comportant, en outre, une ouverture ajustée au passage de l'élément à clé.The invention relates to a protective device for a housing serving to house a control mechanism for a locking fitting embedded in an opening and comprising a key element, of the barrel type, extending through cleanliness plates arranged on the internal and external side of the opening, this device comprising at least one anti-drilling plate disposed on the external side with respect to the housing and made integral with the opening using fixing members accessible from the internal side of this last, this anti-drilling plate further comprising an opening adjusted to the passage of the key element.
La présente invention trouvera son application dans le domaine de la quincaillerie du bâtiment.The present invention will find its application in the field of building hardware.
L'on connaît déjà des dispositifs de protection correspondant à la description précédente. Tout particulièrement, dans le cadre d'une ferrure de verrouillage, du type serrure, crémone-serrure ou analogue, encastrée dans le chant d'un ouvrant correspondant à une porte, fenêtre ou analogue, ladite ferrure comporte un boîtier servant de logement à un mécanisme de commande comprenant, notamment, un élément à clé du type barillet. Ainsi, il a déjà été envisagé de protéger ledit boîtier à l'égard d'agissements d'un aigrefin cherchant à pénétrer, de manière non autorisée, dans des locaux quelconques. En effet, un tel boîtier de ferrure de verrouillage, s'il n'est pas renforcé par des moyens adéquats, ne résiste guère, par exemple au perçage ou encore à la déformation sous l'impulsion d'un levier ou suite à une tentative d'extraction du barillet, notamment.Protection devices corresponding to the preceding description are already known. In particular, in the context of a locking fitting, of the lock, cremone bolt or similar type, embedded in the edge of an opening corresponding to a door, window or the like, said fitting comprises a housing serving as housing for a control mechanism comprising, in particular, a key element of the barrel type. Thus, it has already been envisaged to protect said housing against the actions of a shark seeking to enter, in an unauthorized manner, in any premises. Indeed, such a locking fitting casing, if it is not reinforced by suitable means, hardly resists, for example drilling or deformation under the impulse of a lever or following an attempt barrel extraction, in particular.
Les solutions mises en oeuvre jusqu'à présent consistaient, soit à renforcer les éléments du mécanisme de commande et du boîtier en les modifiant, soit à protéger ledit boîtier en intervenant sur, au moins, la plaque de propreté montée en applique sur la face externe de l'ouvrant. Cette dernière solution est, par exemple, mise en oeuvre dans la ferrure de verrouillage telle que décrite dans le document DE-A-3.604.719.The solutions implemented so far have consisted either in strengthening the elements of the control mechanism and the housing by modifying them, or in protecting said housing by intervening on, at minus, the cleanliness plate mounted on the outside of the door. The latter solution is, for example, implemented in the locking fitting as described in document DE-A-3,604,719.
Tout particulièrement, la plaque de propreté spécifique comporte, sur son côté venant en applique sur l'ouvrant, une plaque anti-perçage, ou encore remplit les fonctions de cette dernière. Elle reçoit, par ailleurs, des douilles taraudées en un matériau spécifique pour la réception d'organes de fixation tels que vis traversant de part en part l'ouvrant, certains pour rejoindre la plaque de propreté interne ou de traiter celle-ci pour lui permettre de jouer ce rôle.In particular, the specific cleanliness plate has, on its side which is applied to the opening, an anti-drilling plate, or even fulfills the functions of the latter. It also receives threaded sockets made of a specific material for receiving fasteners such as screws passing right through the opening, some to reach the internal cleanliness plate or to treat it to allow it to play this role.
Finalement, la plaque de propreté externe comporte des caractéristiques spécifiques (épaisseur, logement pour la réception d'une armature pour l'élément à clé, etc...) lui permettant d'éviter des actions directes sur cet élément à clé.Finally, the external cleanliness plate has specific characteristics (thickness, housing for receiving a frame for the key element, etc.) allowing it to avoid direct actions on this key element.
L'on connaît encore, par le document Fr-A-2.613.750, un dispositif de protection anti-percement d'une serrure à barillet comportant plusieurs éléments résistant au perçage, à savoir un écusson avant blindé pourvu, sous son côté interne, d'une chemise métallique comportant une ouverture pour le passage du barillet sachant que l'écusson n'est pourvu que d'un trou destiné à coïncider avec la face avant du rotor dudit barillet. En outre, ce dispositif comporte une plaque de doublage venant se positionner du côté interne de la paroi de la porte délimitant, extérieurement, le logement recevant la serrure. Ainsi, cette plaque de doublage vient en applique sur le côté externe du boîtier de la serrure. Elle comporte, par ailleurs, un collet annulaire traversant, de part en part, l'ouverture usinée dans cette paroi externe de la porte. A l'intérieur même de ce collet annulaire pénètre la chemise métallique équipant l'écusson avant. En tant qu'enjoliveur ou rosette, l'ensemble reçoit une virole conique, côté externe, montée folle autour de la chemise métallique correspondant à l'écusson avant.We also know, from document Fr-A-2,613,750, an anti-drilling protection device for a cylinder lock comprising several elements resistant to drilling, namely a shielded front escutcheon provided, under its internal side, a metal jacket comprising an opening for the passage of the barrel knowing that the escutcheon is only provided with a hole intended to coincide with the front face of the rotor of said barrel. In addition, this device comprises a doubling plate which is positioned on the internal side of the wall of the door delimiting, externally, the housing receiving the lock. Thus, this doubling plate is applied on the external side of the lock housing. It also comprises an annular collar passing right through the opening machined in this external wall of the door. Even inside this annular collar penetrates the metal jacket fitted to the front badge. As a hubcap or rosette, the assembly receives a conical ferrule, external side, mounted crazy around the metallic shirt corresponding to the front badge.
L'on s'aperçoit que de tels dispositifs de protection antérieurs font appel à des plaques de propreté spécifiques qui, par conséquent, présentent une esthétique qui ne concorde que très rarement avec l'ensemble des plaques de propreté correspondant aux autres ouvrants d'une habitation. Par ailleurs, l'on ne peut raisonnablement envisager de concevoir, pour chaque modèle de plaque de propreté existant, des plaques de propreté aux formes similaires et comportant un dispositif de protection tel que décrit précédemment.It can be seen that such prior protection devices use specific cleanliness plates which, consequently, have an aesthetic which very rarely matches the set of cleanliness plates corresponding to the other opening elements of a dwelling. Furthermore, it cannot reasonably be envisaged to design, for each existing cleanliness plate model, cleanliness plates with similar shapes and comprising a protection device as described above.
En outre, des problèmes se posent pour l'adaptation, après coup, d'un dispositif de protection. En effet, dans ce cas de figure l'usager se voit dans l'obligation de remplacer, purement et simplement, les plaques de propreté existantes.In addition, problems arise for the retrospective adaptation of a protective device. In this case, the user is obliged to replace, purely and simply, the existing cleanliness plates.
Conne déjà indiqué plus haut, parallèlement à ces dispositifs de protection associés aux plaques de propreté, il existe ceux remettant en cause la configuration du boîtier et/ou du mécanisme de commande de la ferrure de verrouillage elle-même Un tel dispositif de protection est notamment décrit dans le document FR-A-2.708.025. Tout particulièrement, ce document décrit un certain nombre de moyens permettant de renforcer l'implantation de l'élément à clé à l'intérieur dudit boîtier. Hormis l'inconvénient principal qui découle de ce dispositif de protection, à savoir la révision totale du boîtier de la ferrure de verrouillage elle-même, d'autres inconvénients découlent d'une telle conception, notamment pour le renforcement, après coup, d'une ferrure de verrouillage, il faut procéder au remplacement de l'ensemble boîtier plus mécanisme de commande.As already indicated above, in addition to these protective devices associated with the cleanliness plates, there are those which call into question the configuration of the housing and / or of the control mechanism of the locking fitting itself. Such a protective device is in particular described in document FR-A-2.708.025. In particular, this document describes a number of means making it possible to strengthen the location of the key element inside said housing. Apart from the main drawback which follows from this protection device, namely the total overhaul of the housing of the locking fitting itself, other drawbacks arise from such a design, in particular for the reinforcement, after the fact, of a locking fitting, the housing assembly plus the control mechanism must be replaced.
La solution selon l'invention se propose de remédier à l'ensemble des inconvénients précités, ceci au travers d'un dispositif de protection qui, tout en rejoignant, du point de vue de l'efficacité, les dispositifs existants, évite toute modification structurelle du boîtier ou encore du mécanisme de commande de la ferrure de verrouillage et permet la réutilisation des plaques de propreté usuelles, moyennant, dans certains cas de figure, une simple reprise d'usinage.The solution according to the invention proposes to remedy all of the aforementioned drawbacks, this through a protection device which, while joining, from the point of view of the efficiency, the existing devices, avoids any structural modification of the housing or of the control mechanism of the locking fitting and allows the reuse of the usual cleaning plates, by means, in certain cases, of a simple resumption of machining.
L'invention telle qu'elle est caractérisée dans les revendications, résout le problème et consiste en un dispositif de protection pour boîtier servant au logement d'un mécanisme de commande d'une ferrure de verrouillage encastrée dans un ouvrant et comprenant un élément à clé, du type barillet, s'étendant au travers de plaques de propreté disposées du côté interne et externe de l'ouvrant, ce dispositif comportant au moins une plaque anti-perçage disposée du côté externe du boîtier et rendu solidaire de l'ouvrant à l'aide d'organes de fixation accessibles du côté interne de ce dernier, cette plaque anti-perçage comportant en outre, une ouverture ajustée au passage de l'élément à clé, caractérisé par le fait que ladite plaque anti-perçage externe vient en applique, directement, sur le côté externe du boîtier et est rendue solidaire de la face interne d'un corps de protection inséré dans un logement usiné du côté externe de l'ouvrant de manière à communiquer avec un entaillage pratiqué dans le chant dudit ouvrant et accueillant le boîtier, ceci de telle sorte que le côté externe du corps de protection vient se positionner à fleur avec le côté externe de l'ouvrant de manière à venir s'escamoter à l'arrière de la plaque de propreté externe.The invention as characterized in the claims, solves the problem and consists of a protective device for a housing serving to house a control mechanism for a locking fitting embedded in an opening and comprising a key element , of the barrel type, extending through cleanliness plates arranged on the internal and external side of the opening, this device comprising at least one anti-drilling plate arranged on the external side of the housing and made integral with the opening to the with the aid of fixing members accessible from the internal side of the latter, this anti-drilling plate further comprising an opening adjusted to the passage of the key element, characterized in that said external anti-drilling plate is applied , directly, on the external side of the case and is made integral with the internal face of a protective body inserted in a housing machined on the external side of the opening so as to communicate with a notch made in the edge of said opening and receiving the housing, so that the external side of the protective body is positioned flush with the external side of the opening so as to retract to the back of the external cleanliness plate.
Préférentiellement, le corps de protection comporte un embout de protection enveloppant le barillet dans sa partie venant s'étendre au travers de la plaque de propreté externe, celle-ci comportant une ouverture ajustée à la section de l'embout de protection.Preferably, the protective body comprises a protective tip enveloping the barrel in its part which extends through the external cleanliness plate, the latter comprising an opening adjusted to the section of the protective tip.

En fait, le dispositif de protection 1, selon l'invention, a pour but de protéger le boîtier 2 d'une ferrure de verrouillage 4 laquelle est encastrée dans l'épaisseur d'un ouvrant 6 correspondant à une porte, par exemple.In fact, the protection device 1, according to the invention, aims to protect the
Il convient d'observer que dans un tel montage l'on trouve, en outre, du côté externe 7, mais aussi, de manière habituelle, du côté interne 8 de cet ouvrant 6, des plaques de propreté, respectivement 9, 10, au travers desquelles s'étend, notamment, l'élément à clé 5. Sur de telles plaques de propreté 9, 10 sont encore montées, usuellement, les poignées permettant d'agir sur le mécanisme de commande de la ferrure de verrouillage.It should be observed that in such an arrangement there are, in addition, on the
Quant au dispositif de protection 1 il comporte une plaque anti-perçage 11 disposée du côté externe 12 par rapport au boîtier 2 et comportant une ouverture 13 ajustée au passage de l'élément à clé 5. Cette plaque anti-perçage 11 est rendue solidaire de l'ouvrant 6 au moyen d'organes de fixation 14 du type vis accessibles du côté interne 8 à l'ouvrant 6.As for the protective device 1, it comprises an
Par conséquent, ces organes de fixation 14 tels que des vis traversent, de part en part l'ouvrant 6 et, donc, le boîtier 2 de manière à venir coopérer, au niveau de leur extrémité 15 avec ladite plaque anti-perçage 11.Consequently, these fixing
A ce propos, celle-ci reçoit des douilles taraudées 16 dans lesquelles viennent se fixer ces vis constituant lesdits organes de fixation 14. A noter qu'en ce qui concerne ces douilles taraudées 16, elles peuvent, là encore, être conçues en un matériau respectant certaines qualités de résistance, telles que dureté et autre, évitant leur dégradation sous les agissements d'un aigrefin.In this regard, the latter receives threaded
En fait, selon l'invention, ladite plaque anti-perçage externe 11 vient en applique directement sur le côté externe 12 du boîtier 2. Elle est, en outre, rendue solidaire de la face interne 17 d'un corps de protection 18 lequel vient s'insérer dans un logement 19, aux dimensions adaptées, usiné du côté externe 7 de l'ouvrant 6. En venant ainsi se positionner dans un fraisage réalisé dans l'ouvrant 6, lui-même, le corps de protection 18, auquel est rendue solidaire la plaque anti-perçage 11, peut aisément venir s'escamoter à l'arrière d'une plaque de propreté 9 aux configurations usuelles. En effet, le côté externe 20 de ce corps de protection 18 peut, ainsi, venir se positionner, sensiblement, à fleur avec le côté externe 7 de l'ouvrant 6.In fact, according to the invention, said external
A noter que ce corps de protection 18 peut recevoir, de manière solidaire, lesdites douilles taraudées 16 destinées à coopérer avec les organes de fixation 14 en vue d'assurer la fixation de la plaque anti-perçage 11 de l'ouvrant 6.It should be noted that this
Le logement 19 accueillant le corps de protection 18 est usiné dans l'ouvrant 6 de manière à communiquer avec l'entaillage 21 pratiqué dans le chant de cet ouvrant 6 et accueillant le boîtier 2 de la ferrure de verrouillage 4, autorisant, précisément, à la plaque anti-perçage 11 de venir directement en applique sur le côté externe 12 du boîtier 2.The
Préférentiellement, ce corps de protection 18 comporte un embout de protection 22 enveloppant l'élément à clé 5 dans sa partie s'étendant au travers de la plaque de propreté externe 9. A ce propos, dans cette dernière, il est usiné une ouverture 23 ajustée à la section de l'embout de protection 22. De plus, la face externe 24 de ce dernier se situe, préférentiellement à fleur avec l'extrémité 26 dudit élément à clé 5 (voir figure 3).Preferably, this
D'une manière usuelle, un élément à clé 5 du type barillet est immobilisé à l'intérieur du boîtier 2 de la ferrure de verrouillage 4 au moyen d'une vis de fixation 27 introduite depuis le chant avant 28 de l'ouvrant 6 et venant coopérer avec un orifice taraudé 29 présent au niveau de cet élément à clé 5.In the usual way, a
Pour un gain de sécurité envers une tentative d'extraction de cet élément à clé 5, celui-ci est également traversé, dans certains cas, par une goupille 30 se présentant saillante, de part et d'autre dudit élément à clé 5. En fait, cette goupille 30 se situe au niveau de la partie 31 de cet élément à clé 5 orientée du côté externe de l'ouvrant 6. Ainsi, il est prévu, selon l'invention, de conférer à la plaque anti-perçage 11 un cambrage 32 de part et d'autre de l'ouverture 13, ces cambrages 32 se situant dans un même plan horizontal que celui de la goupille 30 associée à l'élément à clé 5. De telle manière, les extrémités saillantes de ladite goupille 30 viennent se positionner au niveau de ces cambrages 32 du côté interne à la plaque anti-perçage 11, laquelle peut, ainsi, contribuer, de manière efficace, au maintien de l'élément à clé dans le boîtier 2 en cas d'une tentative d'extraction.For a gain of security towards an attempt to extract this
Selon un mode de réalisation préférentiel, le dispositif de protection 1 comporte, également, une plaque anti-perçage 33 disposé du côté interne au boîtier 2. En réalité, cette plaque anti-perçage 33 vient en applique sur le côté interne 8 de l'ouvrant 6, à l'arrière de la plaque de propreté interne 10. Par conséquent, elle comporte une ouverture 34 autorisant le passage de l'élément à clé 5. De la même manière, d'autres ouvertures 35 sont aménagées au niveau de cette plaque anti-perçage 33 servant au passage des vis constituant les organes de fixation 14.According to a preferred embodiment, the protection device 1 also includes an
Au vu de la description qui précède, l'on constate que le dispositif de protection 1, selon l'invention, peut non seulement être monté, dès l'origine, sur un ouvrant équipé d'une ferrure de verrouillage du type crémone-serrure, serrure ou analogue, mais il est également possible de le rajouter, par la suite, sans grande modification, c'est-à-dire sans remettre en cause l'existant. En effet, il suffit, pour cela, d'entailler légèrement le côté externe de l'ouvrant et de fraiser, au niveau de la plaque de propreté externe, une ouverture autorisant le passage de l'embout de protection 22. Tout particulièrement, ce dispositif de protection 1 est utilisable quasiment avec tout type de plaque de propreté externe 9 ce qui a des avantages, non seulement économiques, mais également d'un point de vue esthétique.In view of the foregoing description, it can be seen that the protection device 1 according to the invention can not only be mounted, from the outset, on an opening fitted with a locking fitting of the lever-lock type. , lock or the like, but it is also possible to add it later, without major modifications, that is to say without calling into question the existing one.
