Description

La présente invention concerne les parois antieffraction, c'est-à-dire aptes à résister aux tentatives frauduleuses de traversée. The present invention relates to burglar-resistant walls, that is to say capable of withstanding fraudulent crossing attempts.

L'invention concerne en particulier, mais non exclusivement, les ouvrants des portes d'habitation. The invention relates in particular, but not exclusively, to the openings of residential doors.

Pour faciliter la compréhension, on décrira dans la suite de la description des portes d'habitation, car celles-ci s'appliquent plus particulièrement à l'invention.To facilitate understanding, a description will be given in the following description of residential doors, since these apply more particularly to the invention.

Les portes d'habitation sont, depuis qu'elles existent, l'objet d'une attention toute particulière de la part des malfaiteurs. Les moyens utilisés par ces derniers pour commettre leurs méfaits ont constamment suivi l'évolution de la technique. De nos jours, les malfaiteurs utilisent, en plus de leur matériel traditionnel (pied de biche, pince-monseigneur), de l'outillage électrique portable (perceuse, scie sauteuse, ...) ; ces divers outils leur permettent de s'attaquer aux matériaux les plus divers. Residential doors have, since their existence, been the object of very special attention on the part of criminals. The means used by the latter to commit their misdeeds have constantly followed the evolution of the technique. Nowadays, criminals use, in addition to their traditional equipment (crowbar, pliers-monseigneur), portable electric tools (drill, jigsaw, ...); these various tools allow them to tackle the most diverse materials.

La constitution des portes d'habitation n'a malheureusement pas suivi cette évolution et, si certaines portes résistent aux attaques de type "traditionnel" (enfoncement à l'aide d'un levier), peu de portes résistent plus de quelques minutes aux attaques plus élaborées (perçage, sciage, tronçonnage, ... à l'aide d'outils à main). Pour obtenir cette résistance, en raison de la diversité des attaques envisageables, les portes dites blindées sont constituées de tôles métalliques de forte épaisseur et de grande dureté. L'inconvénient de ces tôles est de conduire à des éléments lourds, coûteux et difficiles à réaliser à l'aide d'outils courants. The construction of residential doors unfortunately did not follow this development and, if certain doors resist attacks of the "traditional" type (pushing in using a lever), few doors resist more than a few minutes to attacks more elaborate (drilling, sawing, cutting, ... using hand tools). To obtain this resistance, because of the variety of possible attacks, the so-called armored doors are made of metal sheets of great thickness and great hardness. The disadvantage of these sheets is that they lead to heavy, expensive elements which are difficult to produce using standard tools.

La présente invention vient remédier à ces inconvénients et propose à cet effet une nouvelle paroi pour portes d'habitation. L'invention vise, par conséquent, à fournir une paroi utilisant des matériaux simples qui, même si elle ne résiste pas totalement à l'attaque de moyens très puissants, permet cependant de pallier les risques de telles attaques rendant celles-ci à la fois longues et pénibles, de sorte que la durée d'une tentative d'effraction ainsi que les difficultés à vaincre exercent un effet de dissuasion sur un cambrioleur. The present invention overcomes these drawbacks and proposes a new wall for residential doors for this purpose. The invention therefore aims to provide a wall using simple materials which, even if it does not fully resist attack by very powerful means, however, makes it possible to mitigate the risks of such attacks rendering them both long and painful, so that the duration of a break-in attempt as well as the difficulties to overcome have a deterrent effect on a burglar.

Selon l'invention, on obtient une paroi résistant aux actions de découpage, de tronçonnage, de sciage, d'enfoncement et de perçage en combinant différentes couches d'éléments ayant des caractéristiques complémentaires en matière de résistance des matériaux. La combinaison d'assemblage des éléments permet de ne conserver que les qualités de ces derniers, les interactions entre les divers éléments en éliminant les défauts. According to the invention, a wall is obtained which is resistant to cutting, cutting, sawing, driving and drilling actions by combining different layers of elements having complementary characteristics in terms of material resistance. The combination of assembly of the elements makes it possible to retain only the qualities of the latter, the interactions between the various elements eliminating the defects.

Selon l'invention, la paroi composite formant l'ouvrant d'une porte comprend de l'extérieur vers l'int6- rieur un parement extérieur renforcé par une tôle métallique, une première plaque en un matériau de grande dureté résistant aux actions de sciage, une deuxième plaque formant ossature de la paroi, en un matériau de grande rigidité résistant aux actions d'enfoncement, et au moins une garniture fibreuse disposée entre au moins deux des trois élémentsrci-dessus.  According to the invention, the composite wall forming the opening of a door comprises from the outside towards the inside an external facing reinforced by a metal sheet, a first plate made of a material of high hardness resistant to sawing actions. , a second plate forming the framework of the wall, made of a material of great rigidity resistant to the sinking actions, and at least one fibrous lining arranged between at least two of the three elements rci above.

D'autres caractéristiques et avantages de l'invention apparaitront au cours de la description qui va suivre et sur le dessin annexé auquel elle fait référence. Other characteristics and advantages of the invention will appear during the description which follows and in the attached drawing to which it refers.

La figure unique est une vue schématique en coupe de la paroi selon l'invention. The single figure is a schematic sectional view of the wall according to the invention.

Le premier élément 10 est constitué d'un parement 11 en bois (massif, contreplaqué, aggloméré,...) de 4 cm d'épaisseur sur lequel est vissée sur sa face interne une tôle métallique 12 de 1,5 mm d'épaisseur. Cet élément 10 résiste aux actions de découpage et de tron çonnage (dépeçage).  The first element 10 consists of a wooden facing 11 (solid, plywood, agglomerated, ...) 4 cm thick on which is screwed on its internal face a metal sheet 12 1.5 mm thick . This element 10 resists cutting and cutting-off (butchering) actions.

Le deuxième élément 20 est constitué d'une plaque de verre de 4 mm d'épaisseur qui, en raison de sa grande dureté, résiste aux actions de sciage. The second element 20 consists of a glass plate 4 mm thick which, because of its high hardness, resists sawing actions.

- Une garniture fibreuse 40 de 2 mm d'épaisseur est placée de part et d'autre du deuxième élément 20. Elle est destinée, en raison de son élasticité, à amortir tout choc susceptible d'endommager la plaque de verre, et, en raison de par sa nature fibreuse, à gêner les actions de perçage. - A fibrous lining 40 2 mm thick is placed on either side of the second element 20. It is intended, because of its elasticity, to absorb any shock liable to damage the glass plate, and, in due to its fibrous nature, to hinder piercing actions.

Le troisième élément 30 est constitué d'une plaque en tôle métallique façonnable de 2 mm d'épaisseur qui, en raison de sa grande rigidité, résiste aux actions d'enfoncement et de perforation. Cet élément constitue de plus l'ossature de la paroi. The third element 30 consists of a sheet metal sheet that can be shaped 2 mm thick, which, because of its high rigidity, resists penetration and puncturing actions. This element also constitutes the framework of the wall.

La paroi ainsi formée suivant la combinaison décrite ci-dessus, permet de résister à de diverses attaques pouvant êtres subies pendant une tentative d'effraction. The wall thus formed according to the combination described above, makes it possible to resist various attacks which may be suffered during an attempted break-in.

Si on tente de dépecer la paroi, la tôle métallique 12 du premier élément 10 interdira cette action en protégeant le parement 11 trop facilement vulnérable. If an attempt is made to cut up the wall, the metal sheet 12 of the first element 10 will prohibit this action by protecting the facing 11 that is too easily vulnerable.

Si on tente de percer la paroi, la progression de la mèche après une traversée facile du premier élément sera ralentie par la première garniture fibreuse 40, s'enroulant autour de la mèche, puis par la plaque de verre 20, suivie d'une deuxième garniture fibreuse 40 et du troisième élément 30 de grande rigidité. If an attempt is made to pierce the wall, the progression of the wick after an easy crossing of the first element will be slowed down by the first fibrous lining 40, winding around the wick, then by the glass plate 20, followed by a second fibrous lining 40 and the third element 30 of great rigidity.

Si on tente de scier la paroi, soit à l'aide d'une scie sauteuse après avoir réussi le perçage de la paroi, soit à l'aide d'une scie circulaire, la plaque de verre 20 arrêtera cette action malgré le peu de résistance offerte par le premier élément. If an attempt is made to saw the wall, either using a jigsaw after successful drilling of the wall, or using a circular saw, the glass plate 20 will stop this action despite the little resistance offered by the first element.

Et enfin, si on tente d'enfoncer la paroi, le troisième élément, formant ossature de la paroi, résistera à cette action, l'interdisant malgré le peu de résistance à ce type d'attaque des autres éléments.  And finally, if we try to push in the wall, the third element, forming the framework of the wall, will resist this action, prohibiting it despite the little resistance to this type of attack by the other elements.

La paroi formée de ces éléments résiste, par conséquent, aux actions de découpage, de tronçonnage, de sciage, d'enfoncement et de perçage. The wall formed of these elements therefore resists cutting, cutting, sawing, driving and drilling.

Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit, mais s'étend à toute variante conforme à son esprit. Of course, the invention is not limited to the embodiment described, but extends to any variant in accordance with its spirit.

En particulier, le choix du matériau composant le deuxième élément 20 n'est pas limitatif : la plaque de verre peut être remplacée par une tôle de haute dureté recouvrant ou non toute la surface de la paroi.  In particular, the choice of the material making up the second element 20 is not limiting: the glass plate can be replaced by a sheet of high hardness whether or not covering the entire surface of the wall.
