Description

La présente invention a trait d'une façon générale aux portes pour bâtiment, et elle concerne plus particulièrement des perfectionnements aux portes blindées.The present invention relates generally to doors for buildings, and it relates more particularly to improvements to armored doors.

On connaît déjà dans la technique des portes planes blindées qui comprennent un cadre bordé par deux panneaux minces et entre les panneaux, un remplissage incluant une tôle métallique de blindage.There are already known in the art armored flat doors which comprise a frame bordered by two thin panels and between the panels, a filling including a metal sheet of shielding.

Une telle porte est représentée sur la figure 1 des dessins. Comme on peut l'observer, la tôle 130 est encastrée sur une distance relativement courte dans les éléments du cadre 110, réalisé conventionnellement en bois.Such a door is shown in Figure 1 of the drawings. As can be observed, the sheet 130 is embedded over a relatively short distance in the elements of the frame 110, conventionally made of wood.

Un inconvénient de ce type de porte consiste en ce qu'il est extrêmement facile pour un malfaiteur d'arracher la tôle de blindage en la pliant à l'aide d'un outil approprié. Plus précisément, il est relativement aisé, à l'aide d'un pied de biche ou analogue, de venir saisir la tôle par l'arrière, en ayant préalablement attaqué localement le cadre en bois qui emprisonne cette tôle.One drawback of this type of door is that it is extremely easy for a criminal to tear off the shielding sheet by bending it using an appropriate tool. More precisely, it is relatively easy, using a crowbar or the like, to come and grasp the sheet from the rear, having previously attacked locally the wooden frame which traps this sheet.

On connaît également, par exemple par FR-A- 2 581 414 ou US-A-2 165 430, des portes dont le cadre est soit réalisé en métal, soit entièrement entouré d'une tôle. Il est bien évident que de tels cadres, en association avec une tôle de blindage intérieure, peuvent s'avérer satisfaisants en matière de résistance aux effractions. De telles portes sont cependant coûteuses et nécessitent pour leur assemblage des outillages allant bien au-delà des outillages habituels en menuiserie.Also known, for example from FR-A-2 581 414 or US-A-2 165 430, doors whose frame is either made of metal, or entirely surrounded by a sheet. It is quite obvious that such frames, in association with an internal shielding sheet, can be satisfactory in terms of resistance to break-ins. Such doors are however expensive and require for their assembly tools going well beyond the usual tools in carpentry.

La Demanderesse a maintenant découvert que l'on pouvait obtenir des résultats étonnamment bons en matière de résistance à l'effraction en persistant à utiliser un cadre en bois et plus généralement non métallique.The Applicant has now discovered that it is possible to obtain surprisingly good results in terms of resistance to burglary by persisting in using a wooden frame and more generally non-metallic.

Plus précisément, la présente invention vise à pallier les inconvénients de la technique antérieure et à proposer des moyens qui, bien qu'économiques et simples à mettre en place, accroissent grandement la résistance à l'arrachement d'une tôle de blindage encastrée dans un cadre en bois ou analogue.More specifically, the present invention aims to overcome the drawbacks of the prior art and to propose means which, although economical and simple to install, greatly increase the tear resistance of a shielding sheet embedded in a wooden frame or the like.

Ainsi, la présente invention concerne une porte présentant les caractéristiques exposées dans la revendication 1.Thus, the present invention relates to a door having the characteristics set out in claim 1.

Des aspects préférés de la porte selon l'invention sont exposés dans les sous-revendications.Preferred aspects of the door according to the invention are set out in the dependent claims.

D'autres aspects et avantages de la présente invention apparaîtront mieux à la lecture de la description détaillée suivante de formes de réalisation préférées de celle-ci, donnée à titre d'exemple et faite en référence aux dessins annexés, sur lesquels :

  • FIG. 5 is a cross-sectional view of a variant of the second embodiment illustrated in FIG. 4, and
  • - Figure 6 is a cross-sectional view of a planar door combining two embodiments of the invention.

En référence tout d'abord à la figure 1, une porte plane à laquelle s'applique tout particulièrement l'invention, globalement indiquée en 100, comprend un cadre périphérique en bois 110 dont on peut observer les deux montants latéraux 110a, 110b.Referring firstly to FIG. 1, a flat door to which the invention particularly applies, generally indicated at 100, comprises a peripheral wooden frame 110 of which the two lateral uprights 110a, 110b can be observed.

De façon bien connue, deux panneaux 120, 122 sont fixés au cadre de part et d'autre de celui-ci.As is well known, two panels 120, 122 are fixed to the frame on either side of it.

Cette porte plane connue comprend en outre une tôle mince de blindage 130 qui est encastrée par ses bords dans le cadre 110 sur une distance prédéterminée, et des panneaux de remplissage 140, 142, participant également au renfoncement de la porte, sont prévus de part et d'autre de la tôle 130 et occupent tout l'espace délimité par le cadre 110, la tôle 130 et le panneau respectif 120 ou 122.This known flat door further comprises a thin shielding sheet 130 which is embedded by its edges in the frame 110 over a predetermined distance, and filler panels 140, 142, also participating in the recess of the door, are provided on the side and on the other side of the sheet 130 and occupy all the space delimited by the frame 110, the sheet 130 and the respective panel 120 or 122.

Une porte plane de ce type connu présente les inconvénients mentionnés en introduction.A flat door of this known type has the drawbacks mentioned in the introduction.

En référence maintenant aux figures 2 et 3, on a illustré un premier mode de réalisation de l'in­vention, selon lequel un profilé 150 métallique est inter­calé entre le bord de la tôle 130 et l'élément de cadre 110b considéré.Referring now to Figures 2 and 3, there is illustrated a first embodiment of the invention, according to which a metal profile 150 is interposed between the edge of the sheet 130 and the frame element 110b considered.

Ce profilé 150, mieux visible sur la fi­gure 3 comprend deux ailes 150a, 150b coplanaires, présen­tant chacune des trous 152 régulièrement répartis pour des vis de fixation 154 (non illustrées sur la figure 3); les ailes 150a, 150b délimitent entre elles une partie de sec­tion en forme de "U" dont les deux branches sont indiquées en 150c, 150d et dont le sommet est désigné par 150e.This profile 150, better visible in Figure 3 comprises two wings 150a, 150b coplanar, each having holes 152 regularly distributed for fixing screws 154 (not shown in Figure 3); the wings 150a, 150b define between them a section portion in the shape of a "U", the two branches of which are indicated at 150c, 150d and the top of which is designated by 150e.

De préférence, ce profilé métallique est réalisé en tôle pliée. Il est dimensionné de telle sorte que le bord de la tôle de blindage 130 puisse venir se loger étroitement à l'intérieur du "U", comme illustré sur la figure 3.Preferably, this metal profile is made of folded sheet. It is dimensioned so that the edge of the shielding sheet 130 can be fitted tightly inside the "U", as illustrated in FIG. 3.

La face intérieure de l'élément de cadre 120b est creusée comme illustré de telle sorte qu'elle pré­sente une cavité dont la forme est complémentaire de celle du profilé. Ainsi, une fois le profilé 150 monté et fixé en place, les faces extérieures des ailes 150a, 150b, (à gau­che sur les figures 2 et 3) sont en affleurement avec la face intérieure de l'élément de cadre 110b.The inner face of the frame element 120b is hollowed out as illustrated so that it has a cavity whose shape is complementary to that of the profile. Thus, once the section 150 is mounted and fixed in place, the outer faces of the wings 150a, 150b (on the left in FIGS. 2 and 3) are flush with the inner face of the frame element 110b.

De façon préférée, un tel profilé est prévu le long de chacun des éléments verticaux et horizontaux du cadre 110, de manière à ce que les bords de la tôle 130 soient encastrés dans des profilés sur toute la périphérie de la dite tôle.Preferably, such a profile is provided along each of the vertical and horizontal elements of the frame 110, so that the edges of the sheet 130 are embedded in profiles over the entire periphery of said sheet.

Ainsi, la tôle de blindage 130 est encastrée avec une beaucoup plus grande solidité dans le cadre qui l'entoure, ce qui confère à la porte un meilleur comporte­ment à l'effraction.Thus, the shielding sheet 130 is embedded with a much greater solidity in the frame which surrounds it, which gives the door better behavior against break-ins.

Plus précisément, des essais ont permis de constater qu'en ajoutant de tels profilés, en eux-mêmes peu coûteux et faciles à monter, on obtenait un accroissement considérable de la résistance à l'effraction, comme on va le voir plus loin dans des exemples chiffrés.More specifically, tests have shown that by adding such profiles, in themselves little expensive and easy to assemble, a considerable increase in burglary resistance was obtained, as will be seen below in numerical examples.

Bien entendu, dans certains cas, on pourra ne prévoir des profilés 150 que sur une partie de la péri­phérie de la porte, par exemple dans le cas où certaines zones de bordure de la tôle sont en elles mêmes protégées, en position fermée, par des parties du bâti de la porte.Of course, in certain cases, profiles 150 may only be provided on a part of the periphery of the door, for example in the case where certain edge zones of the sheet are in themselves protected, in the closed position, by parts of the door frame.

Le montage d'une porte blindée conforme à ce mode de réalisation de l'invention s'effectue de façon analogue à celui de la porte blindée connue de la figure 1, à ceci près que les éléments de cadre, de section appropriée telle qu'illustrée en figure 2, et les profilés métalliques 150 sont assemblés préalablement à la mise en place du cadre 110 autour du blindage 130.The mounting of an armored door according to this embodiment of the invention is carried out in a similar manner to that of the known armored door of FIG. 1, except that the frame elements, of appropriate section such as illustrated in FIG. 2, and the metal profiles 150 are assembled prior to the installation of the frame 110 around the shield 130.

On a représenté sur la figure 4 un second mode de réalisation de l'invention. Sur cette figure et sur les suivantes, des éléments ou parties identiques ou si­milaires à ceux des figures 1 à 3 sont désignés par les mêmes numéros de référence.FIG. 4 shows a second embodiment of the invention. In this figure and the following, elements or parts identical or similar to those of Figures 1 to 3 are designated by the same reference numbers.

Dans ce mode de réalisation, au moins l'un des montants du cadre 110 comporte, de façon connue, un raidisseur 160 sous la forme d'une poudre profilée de section en "U" qui est encastrée par ses deux branches 160a, 160b dans un élément en bois 110c du cadre; un autre élément de cadre 110d, situé à l'extérieur (à droite sur la figure 4), vient compléter cet assemblage en immobilisant en place la poutre 160.In this embodiment, at least one of the uprights of the frame 110 comprises, in a known manner, a stiffener 160 in the form of a profiled powder of "U" section which is embedded by its two branches 160a, 160b in a wooden element 110c of the frame; another frame element 110d, located outside (on the right in FIG. 4), completes this assembly by immobilizing the beam 160 in place.

Conformément à l'invention, un tel profilé 160 est utilisé pour renforcer le montage du blindage 130 sur le cadre. A cet effet, la tôle 130 est encastrée direc­tement dans une rainure 110e de l'élément de cadre 110c à l'opposé du profilé 160, sur une longueur substantielle telle que les deux branches 160a, 160b dudit profilé vien­nent se situer en vis-à-vis des zones de bordure de la tôle 130.According to the invention, such a profile 160 is used to reinforce the mounting of the shield 130 on the frame. For this purpose, the sheet 130 is embedded directly in a groove 110e of the frame element 110c opposite the profile 160, over a substantial length such that the two branches 160a, 160b of said profile come to face each other. -vis the border areas of the sheet 130.

Pour obtenir une telle configuration, l'élément de cadre 110c est conformé de façon appropriée, c'est-à-dire qu'il présente d'un côté une rainure qui reçoit intimement le bord considéré de la tôle 130, et de l'autre côté deux rainures appartenant à une cavité dont la forme est complémentaire de celle de la poutre 160.To obtain such a configuration, the frame element 110c is suitably shaped, that is to say that it has on one side a groove which intimately receives the edge considered of the sheet 130, and of the on the other side, two grooves belonging to a cavity whose shape is complementary to that of the beam 160.

Dans le présent exemple, la tôle 130 pénètre dans l'espace intérieur du "U" sur environ la moi­tié de sa profondeur.In the present example, the sheet 130 penetrates into the interior space of the "U" over approximately half of its depth.

Bien que la tôle 130 ne soit pas en contact direct avec les branches du profilé métallique, mais soit séparée desdites branches par des parties en bois apparte­nant à l'élément de cadre 110c, on obtient ici encore un ­renforcement important de la porte par rapport à la confi­guration connue de la figure 1.Although the sheet 130 is not in direct contact with the branches of the metal profile, but is separated from said branches by wooden parts belonging to the frame element 110c, here again we obtain a significant reinforcement of the door compared to the known configuration of FIG. 1.

Bien entendu, des profilés tels que 160 peu­vent être prévus tout autour de la tôle 130, le cadre 110 de la porte étant conçu en correspondance. Mais de façon préférée, on prévoit dans une telle porte plane un seul raidisseur 160, disposé verticalement sur toute la hauteur de la porte dans sa région opposée aux gonds et renforçant l'un des grands bords de la tôle, tandis que les trois au­tres bords de ladite tôle seront renforcés par des profilés 150 tels que ceux illustrés sur les figures 2 et 3.Of course, profiles such as 160 can be provided all around the sheet 130, the frame 110 of the door being designed in correspondence. However, in such a planar door, a single stiffener 160 is provided, arranged vertically over the entire height of the door in its region opposite the hinges and reinforcing one of the large edges of the sheet, while the other three edges of said sheet will be reinforced by profiles 150 such as those illustrated in FIGS. 2 and 3.

On a représenté sur la figure 5 une varian­te d'exécution du mode de réalisation de la figure 4. Il est ici prévu, pour améliorer encore la stabilité de la porte, deux raidisseurs 160, 170 disposés tête-bêche comme illustré, le raidisseur 160 étant analogue à celui de la figure 4 dans sa forme, sa disposition et sa fonction. Le raidisseur 170, ici de même forme et de même dimension que la poutre 160, est encastré dans l'élément de cadre 110d adjacent à l'élément 110c. On a illustré sur la figure 6 une variante d'exécution de l'invention dans laquelle il est prévu un double raidisseur 160, 170 le long du grand bord de la tôle opposé aux gonds, c'est-à-dire du côté de la serrure 200, les trois autres bords de la tôle 130 étant renforcés par des profilés semblables à celui des figures 2 et 3.There is shown in Figure 5 an alternative embodiment of the embodiment of Figure 4. It is here provided, to further improve the stability of the door, two stiffeners 160, 170 arranged head to tail as illustrated, the stiffener 160 being analogous to that of FIG. 4 in its form, its arrangement and its function. The stiffener 170, here of the same shape and the same dimension as the beam 160, is embedded in the frame element 110d adjacent to the element 110c. A variant has been illustrated in FIG. 6. of the invention in which a double stiffener 160, 170 is provided along the large edge of the sheet opposite the hinges, that is to say on the side of the lock 200, the three other edges of the sheet 130 being reinforced by profiles similar to that of FIGS. 2 and 3.

On va maintenant indiquer des données con­crètes pour la réalisation des portes blindées conformes à l'invention.We will now indicate concrete data for the production of armored doors according to the invention.

Le cadre 110 peut être réalisé par exemple en bois exotique, en pin ou en sapin, avec une épaisseur de l'ordre de 33 mm.The frame 110 can be made for example of exotic wood, pine or fir, with a thickness of the order of 33 mm.

Les panneaux extérieurs 120, 122 sont avan­tageusement constitués par des feuilles de fibre de bois dur d'une épaisseur de l'ordre de 3 à 4 mm.The exterior panels 120, 122 are advantageously constituted by sheets of hard wood fiber with a thickness of the order of 3 to 4 mm.

La tôle 130 peut être une tôle d'acier, par exemple de 3 mm d'épaisseur.The sheet 130 can be a sheet of steel, for example 3 mm thick.
