Description

La présente invention concerne une structure de blindage de porte conçue pour convenir en particulier, bien que non limitativement, à des travaux de rénovation consistant à blinder une porte existante en conservant son panneau de façade. Elle s'étend non seulement aux portes blindées au moyen d'une telle structure, mais aussi à son utilisation dans la réalisation de blocs-portes à blindage de sécurité. Elle a ainsi pour objet, en particulier, un bloc-porte blindé dans lequel la structure de blindage utilisée pour blinder la porte proprement dite est complétée par une huisserie de dormant, conçue coopérante, dans laquelle la porte vient s'appliquer en position fermée.The present invention relates to a door shielding structure designed to be particularly suitable, although not limited to, renovation work consisting of shielding an existing door while retaining its facade panel. It extends not only to armored doors by means of such a structure, but also to its use in the production of door blocks with security shielding. It thus has as an object, in particular, an armored door block in which the shielding structure used to arm the door itself is supplemented by a frame frame, designed cooperatively, in which the door is applied in the closed position.

Dans le cadre des applications de l'invention à des travaux de rénovation, la structure de blindage suivant l'invention satisfait en particulier aux besoins que l'on rencontre pour des portes palières dans des immeubles à appartements privatifs quand les propriétaires ou locataires souhaitent conserver l'esthétique de leur porte d'entrée. Le même besoin se rencontre aussi, par exemple, pour des maisons de ville qui présentent un caractère ancien à préserver. En outre, on comprendra aisément que la structure de blindage proposée par l'invention peut aussi bien s'utiliser hors travaux de rénovation, sur des panneaux de porte neufs, dans des applications où l'on retrouvera l'avantage de savoir se prêter au choix du client dans une fabrication sur mesure.Within the framework of the applications of the invention to renovation works, the shielding structure according to the invention satisfies in particular the needs which are encountered for landing doors in apartment buildings when the owners or tenants wish to keep the aesthetics of their front door. The same need is also encountered, for example, for townhouses which have an old character to be preserved. In addition, it will be readily understood that the shielding structure proposed by the invention can also be used outside of renovation work, on new door panels, in applications where we will find the advantage of knowing how to lend itself to customer choice in custom manufacturing.

L'art antérieur en la matière est illustré par le document de brevet WO 2015/158610 , qui propose d'envelopper la porte dans une structure métallique faite de différentes tôles fixées les unes aux autres par vissage. Le document de brevet FR2676498 quant à lui s'intéresse à un montage spécifique dans lequel deux pièces s'ajustent par coulissement l'une sur l'autre, et là aussi l'asssemblage se réalise par des vis ou boulons. Dans tous les cas, les dispositions proposées ne permettent pas de satisfaire aux besoins que l'invention vise à obtenir.The prior art in the matter is illustrated by the patent document WO 2015/158610 , which proposes to wrap the door in a metal structure made of different sheets fixed to each other by screwing. The patent document FR2676498 as for him is interested in a specific assembly in which two parts adjust by sliding one on the other, and there also the assembly is carried out by screws or bolts. In all cases, the proposed provisions do not meet the needs that the invention aims to obtain.

L'invention propose une structure de blindage de porte constituée comme il est défini par la revendication 1, par deux tôles chacune configurée par pliage et fixées l'une à l'autre par soudage plat sur plat le long des deux montants de la porte, dans un ensemble intégrant des plaques de remplissage derrière un panneau de façade.The invention provides a door shielding structure constituted as defined by claim 1, by two sheets each configured by folding and fixed to each other by flat welding on flat along the two door jambs, in an assembly integrating filler plates behind a facade panel.

L'invention permet de combiner une bonne qualité de protection anti-effraction tout en assurant une bonne protection coupe-feu et une bonne isolation thermique. Elle permet aussi d'améliorer la qualité d'isolation acoustique qui va en général de pair avec l'isolation thermique.The invention makes it possible to combine a good quality of burglary protection while ensuring good fire protection and good thermal insulation. It also improves the quality of sound insulation which generally goes hand in hand with thermal insulation.

Dans la structure suivant l'invention, la tôle enveloppe qui entoure la tranche de la porte le long des deux montants dans le prolongement de part et d'autre du plateau arrière combine ses effets avec la tôle cuvette qui s'interpose, dans l'épaisseur de la porte, entre le panneau de façade et une plaque de remplissage qui se loge dans la tôle cuvette et s'étend sur toute la surface de la porte à l'arrière du panneau de façade. La plaque centrale qui forme le fond de la cuvette constitue un plateau transversal qui couvre à l'intérieur toute l'étendue de la porte. Il a pour effet de doubler le plateau de face arrière que comporte la tôle enveloppe, mais à distance de lui, la plaque de remplissage se trouvant entre les deux. La protection anti-effraction par tentative de percement à travers la porte s'en trouve d'autant renforcée, mieux que si les deux plaques étaient l'une contre l'autre. D'autre part, les parties métalliques ne sont pas sensibles aux vibrations, grâce à un soudage entre elles qui se réalise plat sur plat sur toute la hauteur des tôles, avantageusement par soudage en bouchon (plug welding).In the structure according to the invention, the envelope sheet which surrounds the edge of the door along the two uprights in the extension on either side of the rear plate combines its effects with the bowl sheet which is interposed, in the thickness of the door, between the front panel and a filler plate which is housed in the bowl sheet and extends over the entire surface of the door behind the front panel. The central plate which forms the bottom of the bowl constitutes a transverse plate which covers inside the whole extent of the door. It has the effect of doubling the rear face plate that the envelope sheet comprises, but at a distance from it, the filling plate being between the two. The burglary protection by attempting to pierce through the door is therefore reinforced, better than if the two plates were one against the other. On the other hand, the metal parts are not sensitive to vibrations, thanks to a welding between them which is carried out flat on flat over the entire height of the sheets, advantageously by plug welding.

Par ailleurs, les bords de la tôle cuvette présentent avantageusement un profil en Z, formant un plat en extension extérieure à partir du plateau central, et par ce plat en débord la tôle vient se fixer en appui à l'intérieur d'un méplat coopérant que la tôle enveloppe forme en suite d'un épaulement extérieur de sa face latérale. De la sorte, les deux plaques, le plateau de face arrière et le plateau transversal de la tôle cuvette, sont rigidement solidarisées l'une de l'autre à l'écart des panneaux internes, panneau de façade et plaque de remplissage. Le plateau intermédiaire que forme la tôle cuvette n'est solidaire ni du panneau de façade ni de la plaque de remplissage. Ce mode de montage contribue au fait que les portes blindées réalisées au moyen de la structure de blindage suivant l'invention font preuve d'un niveau de sécurité que l'on ne savait envisager antérieurement, dans la mesure où les efforts qui viendraient à s'exercer à l'intérieur de la porte ne se transmettent pas directement de l'un à l'autre des panneaux. Mais aussi, la protection est consolidée tout autour de la porte contre les tentatives d'effraction par effet de levier, par exemple au moyen d'une pince monseigneur, car en face arrière la porte se ferme en recouvrement de la feuillure du dormant.Furthermore, the edges of the cup sheet advantageously have a Z-shaped profile, forming a flat in external extension from the central plate, and by this flat projecting the sheet comes to be fixed in abutment inside a cooperating flat that the envelope sheet forms following an external shoulder of its lateral face. In this way, the two plates, the rear face plate and the transverse plate of the bowl sheet, are rigidly secured to one another away from the internal panels, front panel and filling plate. The intermediate plate formed by the bowl sheet is neither integral with the front panel nor with the filler plate. This mounting method contributes to the fact that the armored doors produced by means of the shielding structure according to the invention demonstrate a level of security which was not previously known, insofar as the forces which would come to be exerted inside the door are not transmitted directly from one to the other of the panels. But also, the protection is consolidated all around the door against attempts to break in by leverage, for example by means of a monseigneur pliers, because on the rear face the door closes over the rebate of the frame.

Dans les modes de réalisation préférés de la structure de blindage suivant l'invention, on prévoit avantageusement que la porte puisse contenir plusieurs panneaux internes, en ajoutant une deuxième plaque de remplissage en arrière de celle qui trouve place dans le creux de la tôle cuvette, de manière à remplir par elle l'espace interne ménagé par la structure de blindage dans une partie arrière en extension extérieure liée au profil épaulé de la tôle enveloppe en sa face latérale. Le profil de section droite de la tôle enveloppe rejoint là la plaque de face arrière par un profil en U, venant dans le prolongement du profil en Z décrit du repli formé par-dessus le panneau de façade au méplat en extension extérieure sur lequel se fixe le rebord de la tôle cuvette.In the preferred embodiments of the shielding structure according to the invention, it is advantageously provided that the door can contain several internal panels, by adding a second filling plate behind that which finds its place in the hollow of the bowl sheet, so as to fill by it the internal space provided by the shielding structure in a rear part in external extension linked to the shouldered profile of the sheet metal envelope in its lateral face. The cross section profile of the envelope sheet joins the rear face plate there by a U-shaped profile, extending from the described Z profile of the fold formed over the front panel with the flat surface in external extension on which is fixed. the edge of the bowl sheet.

Dans les formes de mise en oeuvre de l'invention qui se montrent en général le mieux appropriées en réalisation industrielle, le profil de la tôle enveloppe encadrant le bord de la porte peut aussi se définir comme formant un épaulement vers l'extérieur constituant ledit méplat, entre une partie avant qui se replie vers l'intérieur, en pratique à angle droit, pour former le repli emprisonnant le bord du panneau de façade, et une partie arrière de plus large étendue, qui se replie elle-même vers l'intérieur, en pratique également à angle droit, là où le profil se poursuit par la plaque de face arrière.In the embodiments of the invention which generally prove to be the most suitable in industrial production, the profile of the envelope sheet framing the edge of the door can also be defined as forming an outward shoulder constituting said flat , between a front part which folds inwards, in practice at a right angle, to form the fold enclosing the edge of the front panel, and a rear part of wider extent, which folds itself inwards , in practice also at right angles, where the profile continues with the rear face plate.

Cette structure spécifique peut se voir de manière équivalente comme ménageant trois logements à l'intérieur de la tôle enveloppe, avec un premier logement pour le panneau de façade entre le repli avant de la tôle enveloppe et le plateau transversal de la tôle cuvette, un logement intermédiaire pour une plaque de remplissage s'étendant sur une surface identique dans la cavité réceptrice de la tôle cuvette, et un troisième logement pour une autre plaque de remplissage qui s'étend sur une plus grande surface contre la plaque de face arrière.This specific structure can be seen in an equivalent manner as providing three housings inside the envelope sheet, with a first housing for the front panel between the front fold of the envelope sheet and the transverse plate of the bowl sheet, a housing intermediate for a filling plate extending over an identical surface in the receiving cavity of the cup sheet, and a third housing for another filling plate which extends over a larger surface against the rear face plate.

On notera par ailleurs que cette structure suivant l'invention peut avantageusement être configurée et dimensionnée de telle sorte qu'en fonctionnement, lorsque la porte blindée qui en est équipée vient en applique contre l'huisserie de dormant complémentaire, la tôle enveloppe se place comme il est classique dans la feuillure de dormant en sa partie avant, mais que dans le même temps, à l'endroit de sa partie arrière, elle vienne extérieurement en recouvrement de l'huisserie de dormant en obturant ainsi l'intervalle de la feuillure. L'invention apporte de ce fait un complément de sécurité en toutes ses composantes, la tôle ayant principalement effet en anti-effraction, et la plaque de remplissage principalement en isolation.It will also be noted that this structure according to the invention can advantageously be configured and dimensioned such that in operation, when the armored door which is equipped with it comes to apply against the frame of the additional frame, the sheet metal is placed as it is classic in the frame rebate in its front part, but at the same time, at the place of its rear part, it comes outwardly to cover the frame frame, thereby closing the gap in the rebate. The invention therefore provides additional security in all its components, the sheet having mainly anti-burglary effect, and the filling plate mainly in insulation.

Les plaques de remplissage sont faites de matériaux divers, choisis selon des critères en eux-mêmes connus, en général du plâtre, du bois, du verre, se combinant dans une composition adaptée aux performances de coupe-feu ou d'isolation thermique ou acoustique recherchées.The filler plates are made of various materials, chosen according to criteria known in themselves, generally plaster, wood, glass, combining in a composition adapted to the performance of firebreaks or thermal or acoustic insulation. wanted.

The invention will now be more fully described in particular embodiments, chosen to illustrate the preferred characteristics of the invention in its application in renovation for the production of hinged doors with metal shielding, opening by rotation around a vertical upright. This description is made with reference to the figures of the appended drawings, in which:.

  • The figure 7 is the counterpart of the figure 6 for the complete shielding structure of a door block with built-in lock made from the elements of the figure 6 .

On doit comprendre des figures et de la description qui suit que les particularités de réalisation illustrés peuvent se combiner entre elles d'une manière différente de ce qui en est illustré. C'est ainsi notamment que le boîtier dans lequel sont intégrés l'ensemble des mécanismes de verrouillage, qui constitue la serrure 7, peut être au choix soit rapporté extérieurement à la tôle enveloppe 10 et fixé sur elle comme illustré sur la figure 5, soit encastré à l'intérieur de la tôle enveloppe comme illustré sur la figure 7, en combinaison alternativement avec une gâche rapportée comme le montre la figure 4 ou avec la gâche de la figure 6 qui est conformée dans la structure de dormant et vient affleurer avec la plaque de face arrière de la tôle enveloppe, à savoir le plateau 11 de la structure de blindage qui recouvre la porte en sa face arrière.It should be understood from the figures and from the description which follows that the particular features illustrated can be combined with one another in a manner different from what is illustrated therein. Thus, in particular, the housing in which all the locking mechanisms are integrated, which constitutes the lock 7, can be either be attached externally to the casing sheet 10 and fixed on it as illustrated in the figure 5 , either embedded inside the envelope sheet as illustrated on the figure 7 , alternately in combination with an attached keeper as shown in figure 4 or with the keeper of the figure 6 which is shaped in the frame structure and comes flush with the rear face plate of the envelope sheet, namely the plate 11 of the shielding structure which covers the door on its rear face.

Pour la clarté de la description on conviendra d'un vocabulaire suivant lequel, comme il est déjà fait précédemment, on désigne comme la face avant de la porte celle qui est occupée par le panneau de façade, en haut sur les figures en coupe, et comme la face arrière celle qui à l'opposé est recouverte entièrement par la tôle enveloppe. Les faces latérales à gauche et à droite des figures sont celles qui longent les montants de la porte et qui se placent dans la feuillure du dormant lorsque la porte est amenée en position fermée.For the clarity of the description, a vocabulary will be used which, as already done above, is used to designate the front of the door as occupied by the front panel, above in the cross-section figures, and like the rear side, the one opposite it is completely covered by the envelope sheet. The lateral faces to the left and to the right of the figures are those which run along the door jambs and which are placed in the rebate of the frame when the door is brought to the closed position.

De façon courante en rénovation de portes palières, la face avant de la porte se situe à l'extérieur d'un appartement privatif et la face arrière à l'intérieur. C'est donc par la face avant que se produisent en principe les tentatives d'effraction alors que d'autres composantes de la sécurité recherchée, en particulier la fonction coupe-feu, sont plus à traiter par l'ensemble de la porte blindée. Toutefois, tels qu'ils sont conçus et disposés en relation avec les différents éléments de blindage, les éléments internes à la porte participent aussi de la sécurité anti-effraction.Commonly in the renovation of landing doors, the front face of the door is located outside a private apartment and the rear face inside. It is therefore by the front face that break-in attempts occur in principle, while other components of the security sought, in particular the firebreak function, are more to be dealt with by the entire armored door. However, as they are designed and arranged in relation to the various shielding elements, the elements internal to the door also participate in burglar-resistant security.

En pratique, la structure de blindage est réalisée en usine par pliage de tôles découpées aux dimensions fixées pour ses différents éléments constitutifs et par soudage des éléments les uns aux autres, bord à bord en bout de profilé, ou les uns sur les autres plat sur plat au niveau de perforations régulièrement réparties sur la partie courante du profilé. Dans le cas décrit, on a prévu de donner à l'élément de structure venant sur la porte en traverse haute le même profil de section droite que pour les éléments constituant les montants, avec soudure bord à bord des éléments de la traverse haute sur les éléments correspondants des faces de montants.In practice, the shielding structure is produced in the factory by folding sheet metal cut to the dimensions fixed for its various constituent elements and by welding the elements together, edge to edge at the end of the profile, or on each other flat on flat on the level of perforations regularly distributed on the current part of the profile. In the case described, provision has been made to give the structural element coming to the top cross member the same cross section profile as for the elements constituting the uprights, with edge to edge welding of the elements of the top cross member on the corresponding elements of the upright faces.

Finalement, le panneau de façade et les plaques de remplissage sont introduits par glissement à partir de l'extrémité basse de la structure de blindage propre à la porte, avant de la fermer par un élément de tôle utilisé comme traverse de seuil 19 que l'on fixe en bout des profilés de montant.Finally, the front panel and the filler plates are inserted by sliding from the lower end of the door's own shielding structure, before closing it with a sheet metal element used as a threshold cross member 19 that the upright profiles are fixed at the end.

En se référant plus précisément aux figures annexées, on observe qu'une structure de blindage de bloc-porte complète comprend une structure d'ouvrant 1 et une structure de dormant 2. Ces deux ensembles, faits exclusivement de tôles métalliques, sont complétés par des éléments non métalliques propres à la porte, dans lesquels on distingue, un panneau de façade 3 et deux plaques de remplissage interne 4 et 5. Le panneau de façade est encadré par l'ensemble de blindage d'ouvrant, qui recouvre ses bords, mais il reste apparent en face avant dans la majorité de sa surface. Les plaques de remplissage sont, elles, enfermées dans la structure de blindage métallique et non visibles de l'extérieur.Referring more specifically to the appended figures, it can be seen that a complete door block shielding structure comprises a sash structure 1 and a frame structure 2. These two assemblies, made exclusively of metal sheets, are completed by non-metallic elements specific to the door, in which there is a front panel 3 and two internal filling plates 4 and 5. The front panel is framed by the opening armor assembly, which covers its edges, but it remains visible on the front face for most of its surface. The filler plates are themselves enclosed in the metal shielding structure and not visible from the outside.

Les éléments métalliques de la structure de blindage d'ouvrant comprennent essentiellement la tôle enveloppe 10, la tôle cuvette 20; la contre-plaque d'ouvrant 31 du dispositif anti-pince. Une fois ces éléments assemblés en usine, la structure de blindage obtenue reçoit les éléments propres à la porte, à savoir le panneau de façade 3, dont toute la partie centrale reste apparente, une première plaque de remplissage 4, en position intermédiaire entre le panneau de façace et une seconde plaque de remplissage 5.The metallic elements of the opening shielding structure essentially comprise the casing sheet 10, the cup sheet 20; the opening counter plate 31 of the anti-clamp device. Once these elements are assembled in the factory, the shielding structure obtained receives the elements specific to the door, namely the front panel 3, the entire central part of which remains visible, a first filler plate 4, in the intermediate position between the panel. and a second filler plate 5.

De la tôle enveloppe, on voit qu'elle est configurée pour constituer un plateau de face arrière 11 qui se présente ici sous la forme d'une plaque plane. Ce plateau recouvre la porte sur sa face arrière, à l'opposé du panneau de façade. Il s'étend là sur toute la surface de la porte, de l'un à l'autre des deux profilés de montant et de la traverse haute à la traverse de seuil.From the envelope sheet, it can be seen that it is configured to constitute a rear face plate 11 which is here in the form of a flat plate. This tray covers the door on its rear side, opposite the front panel. It extends there over the entire surface of the door, from one to the other of the two upright profiles and from the upper cross member to the threshold cross member.

De ce plateau, la tôle enveloppe 10 se plie à angle droit en se prolongeant par retour sur elle-même afin d'envelopper le pourtour de la porte sur les deux côtés opposés qui définissent les profilés de montant 16 et 17 (figure 1). Elle suit là un profil latéral formant une face latérale 12 sur la tranche de la porte. Ce profil est suivi en face avant de la porte d'un repli 13 qui vient en retour par-dessus le panneau de façade 3. Dans le cas particulier décrit le même profil latéral est appliqué sur un élément formant la traverse haute de la porte (référencée 18 sur la figure 1). Quant à la traverse de seuil 19, elle est simplement constituée suivant un profil de section droite en L dont la branche longue ferme l'espace interne de la porte et dont la branche courte s'applique par-dessus le panneau de façade alors qu'en face arrière la traverse de seuil est fixée sur le plateau arrière.From this plate, the envelope sheet 10 folds at a right angle, extending by return on itself in order to wrap the periphery of the door on the two opposite sides which define the upright profiles 16 and 17 ( figure 1 ). There it follows a lateral profile forming a lateral face 12 on the edge of the door. This profile is followed on the front face of the door by a fold 13 which comes back over the front panel 3. In the particular case described, the same lateral profile is applied to an element forming the upper cross member of the door ( referenced 18 on the figure 1 ). As for the threshold cross member 19, it is simply formed according to a cross section profile in L whose long branch closes the internal space of the door and whose short branch is applied over the facade panel while on the rear face the threshold cross member is fixed to the rear plate.

On détaillera maintenant la constitution des éléments de montant et de l'élément de traverse haute, en traitant arbitrairement le cas particulier du montant qui se situe côté serrure dans la porte terminée. Du côté opposé, les profilés coopérants relevant respectivement de l'ouvrant et du dormant sont simplement complétés par les constituants d'une charnières de toute manière en soi classique.We will now detail the constitution of the upright elements and the top cross member, arbitrarily treating the particular case of the amount which is located on the lock side in the finished door. On the opposite side, the cooperating sections belonging respectively to the opening and the frame are simply supplemented by the components of a hinge in any case in itself conventional.

Au niveau du profilé de montant on distingue deux parties de la tôle enveloppe, avec une partie arrière 15 qui dépase de la partie avant 14 par extension latérale, vers l'extérieur de la porte. C'est dans cette partie de plus grande surface de la porte que prend place la plaque de remplissage 5, en s'étendant jusque dans la partie avant correspondante de la face latérale de l'enveloppe.At the level of the upright profile there are two parts of the envelope sheet, with a rear part 15 which projects from the front part 14 by lateral extension, towards the outside of the door. It is in this part of the larger surface of the door that the filling plate 5 takes place, extending as far as the corresponding front part of the lateral face of the envelope.

La tôle cuvette 20 forme une cavité 23 dont le fond est plan sur toute l'étendue disponible entre les deux profilés de montant, de sorte qu'il est constitué ainsi un plateau transversal de renforcement 21 en une position intermédiaire à l'intérieur de la porte. Sur les bords de ce plateau la tôle cuvette présente un profil latéral en Z, se terminant par un rebord vers l'extérieur qui définit le plat transversal 22 par lequel elle vient s'appliquer sur la face interne de la tôle enveloppe, là où le profil en Z de la tôle enveloppe forme un méplat coopérant 24, sur la face interne d'un épaulement 25 en décroché de la partie avant à la partie arrière de la porte. Tôle cuvette et tôle enveloppe sont solidement fixées l'une à l'autre à ce niveau par soudage plat sur plat sur toute la hauteur de la tôle le long de chaque montant de porte suivant la technique du soudage en bouchon. En variante la même liaison par soudage plat sur plat est réalisée au niveau de la feuillure elle-même, et non sur le méplat 24, lorsque la tôle cuvette ne comporte pas de rebord terminal, ce qui est le cas sur la figure 3.The cup sheet 20 forms a cavity 23, the bottom of which is flat over the entire extent available between the two upright profiles, so that a transverse reinforcing plate 21 is thus formed in an intermediate position inside the door. On the edges of this plate, the cup sheet has a lateral Z-shaped profile, ending with an edge towards the outside which defines the transverse plate 22 by which it comes to be applied on the internal face of the envelope sheet, where the Z profile of the envelope sheet forms a cooperating flat 24, on the internal face of a shoulder 25 off the hook from the front part to the rear part of the door. Cup sheet and envelope sheet are firmly fixed to each other at this level by flat welding on flat over the entire height of the sheet along each door jamb according to the plug welding technique. As a variant, the same connection by flat to flat welding is carried out at the rebate itself, and not on the flat 24, when the cup sheet does not have a terminal rim, which is the case on the figure 3 .

La forme en cuvette de la tôle cuvette ménage entre le fond de la cuvette et le niveau de son rebord soudé sur la tôle enveloppe un espace dans lequel prend place la première plaque de remplissage 4. Quant à la seconde plaque de remplissage 5, elle jouxte la première sur une épaisseur allant jusqu'au plateau de face arrière 11. Elle s'étend là transversalement jusqu'au fond de la partie arrière 15 de la tôle enveloppe de chaque côté de la porte, dans l'espace délimité par le profil en U en extension extérieure, où elle est coincée entre le méplat 24 sur lequel prend appui le rebord de la cuvette et le plateau de face arrière 11.The bowl-shaped shape of the sheet pan household between the bottom of the bowl and the level of its rim welded to the sheet wraps a space in which takes place the first filling plate 4. As for the second filling plate 5, it adjoins the first over a thickness up to the rear face plate 11. It extends there transversely to the bottom of the rear part 15 of the sheet metal envelope on each side of the door, in the space delimited by the profile in U in external extension, where it is wedged between the flat 24 on which the rim of the bowl bears and the rear face plate 11.

Les éléments de base que l'on a décrits jusqu'à maintenant se retrouvent à l'identique, avec donc les mêmes références numériques, sur les variantes de réalisation suivant l'invention illustrées par les figures 4 à 7. Les figures 6 et 7 illustrent un mode de mise en œuvre de l'invention particulièrement élaboré, où l'on trouvent réunies des caractéristiques secondaires de l'invention qui concernent respectivement la serrure, la gâche et le dispositif anti-pince.The basic elements that have been described so far are found identically, therefore with the same reference numbers, on the variant embodiments according to the invention illustrated by the figures 4 to 7 . The Figures 6 and 7 illustrate a particularly elaborate embodiment of the invention, in which secondary features of the invention are found which relate respectively to the lock, the keeper and the anti-clamp device.

Sur les figures 4 et 5 on a considéré que la porte est équipée d'une serrure multipênes 7 qui est fixée sur la face externe du plateau de face arrière 11. On en a illustré un pêne 44 en position déployée hors du boîtier. Pour venir en regard quand la porte est en position de fermeture, on a prévu une gâche de fabrication autonome. Cette gâche 59 est réalisée à partir d'une tôle fermée sur elle-même dont une face 57 est évidée d'autant d'empênages que la serrure comporte de pênes, dans une disposition relative en correspondance mutuelle. Elle est soudée sur le profilé de montant de dormant 50, sur sa face arrière 58 habillant un dormant fixe existant (mur ou cloison 48 sur la figure 2).On the Figures 4 and 5 it was considered that the door is equipped with a multi-bolt lock 7 which is fixed to the external face of the rear face plate 11. A bolt 44 has been illustrated in the deployed position out of the housing. To come opposite when the door is in the closed position, an independent production keeper has been provided. This keeper 59 is produced from a sheet closed on itself, one face 57 of which is hollowed out by as many hinges as the lock comprises bolts, in a relative arrangement in mutual correspondence. It is welded to the frame upright section 50, on its rear face 58 covering an existing fixed frame (wall or partition 48 on the figure 2 ).

Sur les figures 6 et 7 la gâche est fabriquée d'une seule pièce avec la feuillure. La structure de blindage de dormant est essentiellement constituée par une tôle de dormant 50 qui est configurée de manière à compléter un profil en Z définissant la feuillure 51 par une partie arrière 55 à profil en U dont la face latérale 57 se situant la première dans le prolongement de la feuillure forme la gâche, évidée d'empênages 56. On notera que l'on a admis ici que la conformation du blindage de dormant apporte une rigidité suffisante au niveau de la gâche pour que l'on puisse se dispenser du doublage renforçant que l'on a fait apparaître sur la figure 2 sous la forme d'une âme de gâche 47.On the Figures 6 and 7 the keeper is made in one piece with the rebate. The frame shielding structure is essentially constituted by a frame sheet 50 which is configured so as to complete a Z profile defining the rabbet 51 by a rear part 55 with a U profile, the side face 57 of which is located first in the extension of the rebate forms the keeper, hollowed out from the 56. It should be noted that it has been admitted here that the conformation of the frame shielding provides sufficient rigidity at the keeper so that the reinforcing lining can be dispensed with that we have shown on the figure 2 in the form of a waste core 47.

On observe sur ces figures 6 et 7, comme d'ailleurs sur les figures 4 et 5, que la tôle constituant la structure de blindage de dormant, au niveau de la feuillure 51, présente des creusures longitudinales 53 dans lesquelles prennent place des joints intumescents plats 52. La figure illustre aussi la présence d'autres joints intumescents de part et d'autre de la feuillure, l'un à l'avant sur le blindage de dormant, l'autre à l'arrière sur l'épaulement 25 de la face latérale du blindage d'ouvrant, là où la porte vient en recouvrement de la feuillure quand elle est en position fermée.We observe on these Figures 6 and 7 , as elsewhere on Figures 4 and 5 , that the sheet constituting the frame shielding structure, at the rebate 51, has longitudinal recesses 53 in which take place intumescent flat joints 52. The figure also illustrates the presence of other intumescent joints on both sides other of the rebate, one at the front on the frame armor, the other at the rear on the shoulder 25 of the side face of the opening shield, where the door overlaps the rebate when it is in the closed position.

La serrure 7 de la figure 7 est montrée encastrée dans la structure de blindage d'ouvrant, où elle se glisse dans une coulisse 41 qui a été intégrée auparavant dans cette structure (figure 6). La coulisse en question prend place dans un espace ménagé pour elle par déformation de la tôle enveloppe 10. Plus précisément, le plateau de face arrière 11 présente à cette fin un profil étagé formant un palier en saillie vers l'arrière 42 qui revient au droit du profil de face latérale 12 rejoindre celui-ci par une face plane 43 formant une têtière livrant passage aux pênes de verrouillage 44 de l'équipement de serrurerie de la porte. À cet endroit, la coulisse est globalement liée solidaire de la tôle enveloppe, en particulier par des points de soudure sur le plateau de face arrière 11 au niveau du palier extérieur 42.Lock 7 of the figure 7 is shown embedded in the sash shielding structure, where it slides into a slide 41 which was previously integrated into this structure ( figure 6 ). The slide in question takes place in a space provided for it by deformation of the envelope sheet 10. More specifically, the rear face plate 11 has for this purpose a stepped profile forming a bearing projecting towards the rear 42 which returns to the right of the side face profile 12 join it by a flat face 43 forming a headrest giving passage to the locking bolts 44 of the door locksmith equipment. At this point, the slide is generally linked integral with the envelope sheet, in particular by weld points on the rear face plate 11 at the level of the external bearing 42.

En ce qui concerne le dispositif anti-pince, la même configuration est utilisée dans les différentes figures. On notera toutefois que, tout en restant dans le cadre de l'invention, il n'est pas exclu d'avoir recours à une configuration moins élaborée. De ce point de vue, comme d'ailleurs pour clarifier si besoin d'autres détails des modes de réalisation des bloc-portes blindés décrits ici, on pourra utilement se reporter au descriptif de la demande de brevet français du 25 avril 2005 publiée sous le numéro 2 884 851 .With regard to the anti-clamp device, the same configuration is used in the different figures. Note however that, while remaining within the scope of the invention, it is not excluded to have recourse to a less elaborate configuration. From this point of view, as indeed to clarify if necessary other details of the embodiments of the armored door units described here, one can usefully refer to the description of the French patent application of April 25, 2005 published under number 2,884,851 .

Le dispositif anti pince fait coopérer la structure de blindage d'ouvrant avec l'élément de dormant 50 par le fait que ce dernier vient coiffer une aile 32 qui pointe en saillie de la face avant de l'ouvrant quand la porte est amenée en position fermée. A l'opposé de la gâche, en avant du dormant, le profil de la tôle de dormant 50 prolonge le profil en Z de la feuillure 51 par un profil en U définissant le contour d'une gorge 36. Cette gorge est en pratique suffisamment large pour que l'aile proéminente 32 de la structure d'ouvrant y pénètre sans difficulté dans toutes les positions relatives entre ouvrant et dormant. Au lieu de constituer l'aile 32 par un repli terminal de la face avant 13 de la tôle enveloppe, on a préféré ici la constituer par un repli d'une contre-plaque différente 31, rendue solidaire de la structure de blindage d'ouvrant par soudage plat sur plat sur la face extérieur du repli transversal 13 de la tôle enveloppe encadrant le panneau de façade. Accessoirement, on a illustré en trait mixte la position que prend le cylindre du mécanisme de commande de verrouillage, en traversant la contre-plaque 31 à l'écart du repli de face avant 13 de la tôle enveloppe.The anti-clamp device makes the sash shielding structure cooperate with the sash element 50 by the fact that the latter comes over a wing 32 which protrudes from the front face of the sash when the door is brought into position closed. Opposite the keeper, in front of the frame, the profile of the frame sheet 50 extends the Z-profile of the rebate 51 by a U-shaped profile defining the outline of a groove 36. This groove is in practice sufficiently wide so that the protruding wing 32 of the sash structure penetrates there without difficulty in all the relative positions between sash and frame. Instead of constituting the wing 32 by a terminal fold of the front face 13 of the envelope sheet, it was preferred here to constitute it by a fold of a different counter plate 31, made integral with the leaf shielding structure by flat welding on flat on the outside face of the transverse fold 13 of the envelope sheet framing the front panel. Incidentally, the position is illustrated in dashed lines. that takes the cylinder of the locking control mechanism, crossing the counterplate 31 away from the front face fold 13 of the envelope sheet.

Serrure et gâche ont été décrits en admettant que, comme il est en général préférable en blindage de sécurité, la serrure est du type à pênes multiples répartis sur la hauteur du montant de porte correspondant, le cas échéant complétés par des pênes d'extrémité. Mais il est clair que l'invention ne se limite pas à ce genre de situation. Pour la figure 1 on a choisi au contraire le cas d'une serrure à pêne unique au niveau d'une clé de déverrouillage à hauteur d'homme.Lock and strike have been described by admitting that, as it is generally preferable in security shielding, the lock is of the type with multiple bolts distributed over the height of the corresponding door jamb, if necessary supplemented by end bolts. But it is clear that the invention is not limited to this kind of situation. For the figure 1 on the contrary, the case of a single bolt lock was chosen at the level of an unlocking key at breast height.
