Definitions

  • the present invention relates to a burglar-resistant door which includes a frame to be integrated into a opening and a leaf hinged on the side of a first edge on the door frame and fitted with a second edge on the side, opposite the first edge, a locking device.
  • the locking device most often a lock fitted with a bolt which engages in a keeper fixed to the frame, is generally a weak point in terms of resistance of the door to a physical attack. Indeed, if we manage to apply to leaf, especially at the bolt, a significant effort, which has a component perpendicular to the leaf and oriented towards the opening of the door, we manage to break the bolt and / or to force the strike.
  • a simple instrument, conventionally used to making such an effort is a lever, for example a crowbar or a sturdy screwdriver.
  • This lever is introduced in a joint necessarily remaining between the leaf and the door frame when the door is in the closed position. We then gradually increases the thickness of this joint, up to create a fulcrum inside the joint sufficient for the tip of the lever.
  • a significant effort on the leaf In an operation ultimate we exercise finally, using the lever in support of inside the joint, a significant effort on the leaf. The component perpendicular to the leaf of this effort then break the bolt.
  • a known and obvious solution to increase the resistance to such a break-in to the lever is further increase the rigidity of the jamb and leaf and to use a locking device with very high mechanical resistance. It is however obvious that such a solution is not only expensive, but also has the disadvantage of making the heavier leaf.
  • a burglar-resistant door can be designed to resist break-in either from the "hinge side", or from the “side opposite the hinges ".
  • hinge side we mean the side of the door where you can see the hinges, while by “face opposite the hinges” means the side of the door where you can't see the hinges.
  • the problem underlying the present invention is to further reduce the possibilities of attacking with success a door using a lever introduced, at the level of the locking device, between the jamb and the leaf.
  • this problem finds on the one hand its solution in a burglar-proof door designed for resist break-in from the hinge side, which is characterized in that said second song of the leaf is extended laterally, at least at the level of the locking device, by a metal strip which protrudes from the leaf so as to penetrate, when closing the door, in a slot corresponding which is arranged in the thickness of the jamb in the extension of the defined joint, in closed position of the door, between said second edge of the leaf and doorframe.
  • this problem finds on the other hand its solution in a burglar-proof door designed for resist break-in from the opposite side hinges, which is characterized in that the jamb is bordered laterally on the side fitted with the locking, at least at the level of the locking, by a flat metal strip which protrudes in protruding so as to penetrate, when closing the door, in a corresponding slot of the leaf which is arranged in the thickness of the leaf along said second leaf song.
  • the main advantage of the present invention is, that at the locking device, it is hardly possible to create, by forcing the joint between the leaf and doorframe at this level, a fulcrum for a lever. Indeed, the slot and the metal strip cooperate to lock the leaf in the doorframe. Of more, even if we manage to get into the slot with a lever, we can't find a support to exercise perpendicularly on the leaf a significant effort. In effect, the protruding metal strip is not rigid enough to constitute a fulcrum for a lever.
  • this invention solves the problem of burglary protection of doors from the "hinge side".
  • the present invention is therefore advantageously applicable to all doors which must, for reasons for evacuation, open to the outside of a room.

But in some applications it may be sufficient to limit the solution proposed to the segment (s) of said neighboring second side the locking device (s). This is especially the case when the locking device itself has a high intrinsic mechanical resistance. With a device of normal mechanical resistance locking, we have the more often interest in applying the solution proposed by the invention over the entire length of the side provided with the locking device.
  • the two solutions proposed at the same time eliminate the possibility of removing the two jambs relative to each other; by example using a cylinder mounted between the two amounts.
  • the leaf forms a sort of staple which connects the two uprights of the frame and thus increases the rigidity of the latter in closed position of the door.
  • the slot according to the invention can for example be delimited laterally by two parallel surfaces, i.e. define a channel section in "U".
  • said slot advantageously has a passage section closely followed, in the direction of penetration of the element in protrusion, unilateral enlargement.
  • a door burglar resistant designed to withstand burglary from the hinge side this is a widening unilateral towards the leaf.
  • a burglar-proof door designed to resist break-in from on the side opposite the hinges it is a unilateral widening in the direction of the jamb. In both cases a significant push on the end of the protruding metal strip deforms the latter, so that it enters the widening of the slot and clings to it.
  • the slot is advantageously defined by an element reported on the jamb. This is for example a "U" shaped profile, a first branch of which is provided with a rim oriented towards the second branch, so as to define for the protruding element a narrow passage section between the edge of the first branch and the second plugged. It is of course also possible to integrate, by example of machining or forming, the slot directly in the jamb, respectively in the leaf.
  • the present invention could naturally also be applied to a window, the chassis must have a high resistance to break-in using a lever. Nor is it excluded from applying it to a door of a chest.

If it were not not the case we could actually exercise using a lever a significant pressure on the leaf 116 in the opening direction of door 110. However, such pressing door 110 would quickly jeopardize its resistance to break-in, because it is essentially the locking device, most often the bolt of a lock, which must resume this effort perpendicular to the leaf 116. It is indeed well known that the lock is, in the majority of cases, the element presenting the lowest mechanical resistance of the frame system 114 / leaf 116.
  • leaf 116 comes quickly abut with its surface 142, respectively the ledge 148 against ledge 136 of the frame 114. It it follows that such solicitation should no longer be taken up entirely by the hinges of the leaf 116.

Description

La présente invention concerne une porte anti-effraction qui comprend un chambranle à intégrer dans une ouverture et un vantail articulé du côté d'un premier chant sur le chambranle et muni du côté d'un deuxième chant, opposé au premier chant, d'un dispositif de verrouillage.The present invention relates to a burglar-resistant door which includes a frame to be integrated into a opening and a leaf hinged on the side of a first edge on the door frame and fitted with a second edge on the side, opposite the first edge, a locking device.

Il est connu de renforcer des portes pour leur conférer une meilleure résistance contre des effractions physiques. Le plus souvent les améliorations apportées à des portes en vue d'augmenter leur caractère anti-effraction consistent dans des mesures qui visent, d'un côté, à augmenter la rigidité du vantail et/ou du chambranle et, de l'autre côté, à utiliser des matériaux soit mécaniquement plus résistants, soit plus résistants aux différents outils utilisés pour percer ces matériaux.It is known to strengthen doors to give them better resistance against physical break-ins. Most often the improvements made to doors in to increase their burglary resistance consist in measures which aim, on the one hand, to increase the stiffness of the leaf and / or door frame and, on the other side to use materials either mechanically more resistant, or more resistant to different tools used to drill these materials.

Il est aussi connu que le dispositif de verrouillage, le plus souvent une serrure munie d'un pêne qui s'engage dans une gâche solidaire du chambranle, est généralement un point faible du point de vue résistance de la porte à une attaque physique. En effet, si on arrive à appliquer au vantail, surtout au niveau du pêne, un important effort, qui a une composante perpendiculaire au vantail et orientée en direction de l'ouverture de la porte, on arrive à casser le pêne et/ou à forcer la gâche.It is also known that the locking device, most often a lock fitted with a bolt which engages in a keeper fixed to the frame, is generally a weak point in terms of resistance of the door to a physical attack. Indeed, if we manage to apply to leaf, especially at the bolt, a significant effort, which has a component perpendicular to the leaf and oriented towards the opening of the door, we manage to break the bolt and / or to force the strike.

Un instrument simple, utilisé classiquement pour produire un tel effort, est un levier, par exemple un pied-de-biche ou un tournevis robuste. Ce levier est introduit dans un joint subsistant nécessairement entre le vantail et le chambranle lorsque la porte est en position fermée. On augmente alors progressivement l'épaisseur de ce joint, jusqu'à créer à l'intérieur du joint un point d'appui suffisant pour la pointe du levier. Dans une opération ultime on exerce finalement, à l'aide du levier en appui à l'intérieur du joint, un effort important sur le vantail. La composante perpendiculaire au vantail de cet effort casse alors le pêne.A simple instrument, conventionally used to making such an effort is a lever, for example a crowbar or a sturdy screwdriver. This lever is introduced in a joint necessarily remaining between the leaf and the door frame when the door is in the closed position. We then gradually increases the thickness of this joint, up to create a fulcrum inside the joint sufficient for the tip of the lever. In an operation ultimate we exercise finally, using the lever in support of inside the joint, a significant effort on the leaf. The component perpendicular to the leaf of this effort then break the bolt.

Une solution connue et évidente pour augmenter la résistance à une telle effraction au levier, est d'augmenter davantage la rigidité du chambranle et du vantail et d'utiliser un dispositif de verrouillage présentant une résistance mécanique très élevée. Il est cependant évident qu'une telle solution n'est pas seulement chère, mais présente aussi l'inconvénient de rendre le vantail plus lourd.A known and obvious solution to increase the resistance to such a break-in to the lever, is further increase the rigidity of the jamb and leaf and to use a locking device with very high mechanical resistance. It is however obvious that such a solution is not only expensive, but also has the disadvantage of making the heavier leaf.

Il est important de noter qu'une porte anti-effraction peut être conçue pour résister à une effraction soit à partir de la "face charnières", soit à partir de la "face opposée aux charnières". Par "face charnières" on entend le côté de la porte d'où on voit les charnières, alors que par "face opposée aux charnières" on entend le côté de la porte d'où on ne voit pas les charnières.It is important to note that a burglar-resistant door can be designed to resist break-in either from the "hinge side", or from the "side opposite the hinges ". By" hinge side "we mean the side of the door where you can see the hinges, while by "face opposite the hinges" means the side of the door where you can't see the hinges.

Dans le document FR-A-918.440 on présente une porte anti-effraction conçue pour résister à une effraction à partir de la face opposée aux charnières. Dans ce document il est proposé de renforcer par des moulures massives les chants verticaux du chambranle et du vantail qui définissent, en position fermée de la porte, le joint entre le chambranle et le vantail. Ces moulures ont pour but de renforcer mécaniquement ces chants et de s'emboíter pour former un joint courbe dans lequel il serait apparemment impossible d'introduire un levier. Cependant, il faut toujours prévoir en pratique un jeu fonctionnel suffisant entre les deux moulures, ce qui permet de trouver un premier appui pour un levier. Ce premier appui permet alors d'accroítre encore davantage le jeu initial pour trouver un appui suffisant pour forcer le dispositif de verrouillage.In the document FR-A-918.440 a door is presented burglar resistant designed to withstand burglary from the side opposite the hinges. In this document it is proposed to reinforce by massive moldings the vertical chants of the doorframe and leaf which define, in the closed position of the door, the joint between the doorframe and the door leaf. These moldings are intended to mechanically reinforce these songs and fit together to form a curved joint in which it would apparently impossible to introduce a lever. However, it is necessary always in practice provide sufficient functional clearance between the two moldings, which makes it possible to find a first press for a lever. This first press then allows to further increase the initial game to find a sufficient support to force the locking device.

Dans le document FR-A-2.590.928 on présente également une porte anti-effraction conçue pour résister à une effraction à partir de la face opposée aux charnières. Des rebords du chambranle et du vantail se recouvrent partiellement en position fermée de la porte, de façon à rendre inaccessibles les deux joints latéraux entre le vantail et le chambranle. Il sera cependant remarqué que ces rebords sont facilement accessibles du côté effraction, ce qui réduit naturellement leur efficacité.In document FR-A-2,590,928 we also present a burglar-resistant door designed to withstand break-in from the side opposite the hinges. Of edges of the door frame and leaf overlap partially in the closed position of the door, so that make the two side seals between the leaf and doorframe. It will however be noticed that these edges are easily accessible from the burglary side, which naturally reduces their effectiveness.

Dans le document EP-A-0.389.532 sont décrits des dispositifs de protection conçus pour renforcer, a posteriori, la résistance d'une porte contre une effraction à partir de la face opposée aux charnières. Les dispositifs présentés sont essentiellement basés sur l'idée de bloquer par des profilés du côté effraction, en l'occurrence le côté opposé aux charnières, l'accès au joint entre le vantail et le chambranle au niveau du dispositif de verrouillage. Il sera noté que les profilés décrits dans le document EP-A-0.389.532 peuvent être très facilement attaqués du côté effraction. Leur efficacité est par conséquent douteuse, en particulier si les exigences en ce qui concerne la protection anti-effraction sont élevées.In document EP-A-0.389.532 are described protective devices designed to strengthen, a posteriori, the resistance of a door against a break-in from the side opposite the hinges. The devices presented are essentially based on the idea of blocking by profiles on the burglary side, in this case the side opposite the hinges, access to the joint between the leaf and frame at the level of the locking. It will be noted that the profiles described in the document EP-A-0.389.532 can be very easily attacked from the break-in side. Their effectiveness is by therefore questionable, especially if the requirements regarding burglary protection are high.

Dans le document DE-U-9202349 est décrite une porte anti-effraction comprenant un chant de vantail qui est muni d'une bande métallique légèrement en saillie par rapport au vantail. Cette partie en saillie, qui pénètre dans une fente correspondante du chambranle lors de la fermeture de la porte, aurait pour but de créer une sorte de joint labyrinthe rendant impossible un passage d'un objet à travers le joint et/ou une pénétration profonde d'un outil dans le joint.In document DE-U-9202349 a door is described burglar-resistant including a leaf edge which is provided a metal strip slightly projecting from the leaf. This projecting part, which penetrates into a corresponding slot in the door frame when closing the door, would aim to create a kind of joint labyrinth making it impossible to pass from an object to through the seal and / or deep penetration of a tool in the joint.

Le problème à la base de la présente invention est de réduire encore davantage les possibilités d'attaquer avec succès une porte à l'aide d'un levier introduit, au niveau du dispositif de verrouillage, entre le chambranle et le vantail.The problem underlying the present invention is to further reduce the possibilities of attacking with success a door using a lever introduced, at the level of the locking device, between the jamb and the leaf.

Selon l'invention ce problème trouve d'un côté sa solution dans une porte anti-effraction conçue pour résister à une effraction à partir de la face charnières, qui est caractérisée en ce que ledit deuxième chant du vantail est prolongé latéralement, au moins au niveau du dispositif de verrouillage, par une bande métallique qui est en saillie par rapport au vantail de façon à pénétrer, lors de la fermeture de la porte, dans une fente correspondante qui est agencée dans l'épaisseur du chambranle dans le prolongement du joint défini, en position fermée de la porte, entre ledit deuxième chant du vantail et le chambranle.According to the invention this problem finds on the one hand its solution in a burglar-proof door designed for resist break-in from the hinge side, which is characterized in that said second song of the leaf is extended laterally, at least at the level of the locking device, by a metal strip which protrudes from the leaf so as to penetrate, when closing the door, in a slot corresponding which is arranged in the thickness of the jamb in the extension of the defined joint, in closed position of the door, between said second edge of the leaf and doorframe.

Selon l'invention ce problème trouve d'un autre côté sa solution dans une porte anti-effraction conçue pour résister à une effraction à partir de la face opposée aux charnières, qui est caractérisée en ce que le chambranle est bordé latéralement du côté muni du dispositif de verrouillage, au moins au niveau du dispositif de verrouillage, par une bande métallique plane qui dépasse en saillie de façon à pénétrer, lors de la fermeture de la porte, dans une fente correspondante du vantail qui est agencée dans l'épaisseur du vantail le long dudit deuxième chant du vantail.According to the invention this problem finds on the other hand its solution in a burglar-proof door designed for resist break-in from the opposite side hinges, which is characterized in that the jamb is bordered laterally on the side fitted with the locking, at least at the level of the locking, by a flat metal strip which protrudes in protruding so as to penetrate, when closing the door, in a corresponding slot of the leaf which is arranged in the thickness of the leaf along said second leaf song.

Le principal avantage de la présente invention est, qu'au niveau du dispositif de verrouillage, il n'est guère possible de créer, par un forcement du joint entre le vantail et le chambranle à ce niveau, un point d'appui pour un levier. En effet, la fente et la bande métallique coopèrent pour bloquer le vantail dans le chambranle. De plus, même si on arrive à pénétrer dans la fente avec un levier, on n'arrive pas à trouver un appui pour exercer perpendiculairement sur le vantail un effort important. En effet, la bande métallique en saillie n'est pas suffisamment rigide pour constituer un point d'appui pour un levier.The main advantage of the present invention is, that at the locking device, it is hardly possible to create, by forcing the joint between the leaf and doorframe at this level, a fulcrum for a lever. Indeed, the slot and the metal strip cooperate to lock the leaf in the doorframe. Of more, even if we manage to get into the slot with a lever, we can't find a support to exercise perpendicularly on the leaf a significant effort. In effect, the protruding metal strip is not rigid enough to constitute a fulcrum for a lever.

Il sera particulièrement apprécié que la présente invention résout le problème de la protection anti-effraction de portes à partir de la "face charnières". La présente invention est par conséquent avantageusement applicable à toutes les portes qui doivent, pour des raisons d'évacuation, s'ouvrir vers l'extérieur d'un local.It will be particularly appreciated that this invention solves the problem of burglary protection of doors from the "hinge side". The present invention is therefore advantageously applicable to all doors which must, for reasons for evacuation, open to the outside of a room.

La solution proposée est de préférence appliquée sur sensiblement toute la longueur dudit deuxième côté muni du dispositif de verrouillage. Mais dans quelques applications il pourrait s'avérer suffisant de limiter la solution proposée au(x) segment(s) dudit deuxième côté avoisinant le(s) dispositif(s) de verrouillage. Ceci est surtout le cas lorsque le dispositif de verrouillage a lui-même une résistance mécanique intrinsèque élevée. Avec un dispositif de verrouillage de résistance mécanique normale, on a le plus souvent intérêt à appliquer la solution proposée par l'invention sur toute la longueur du côté muni du dispositif de verrouillage.The proposed solution is preferably applied to substantially the entire length of said second side provided with the locking device. But in some applications it may be sufficient to limit the solution proposed to the segment (s) of said neighboring second side the locking device (s). This is especially the case when the locking device itself has a high intrinsic mechanical resistance. With a device of normal mechanical resistance locking, we have the more often interest in applying the solution proposed by the invention over the entire length of the side provided with the locking device.

Il sera aussi noté que les deux solutions proposées éliminent en même temps la possibilité d'écarter les deux montants du chambranle l'un par rapport à l'autre; par exemple en utilisant un vérin monté entre les deux montants. Dans les deux solutions proposées, le vantail forme une sorte d'agrafe qui relie les deux montants du chambranle et augmente ainsi la rigidité de ce dernier en position fermée de la porte.It will also be noted that the two solutions proposed at the same time eliminate the possibility of removing the two jambs relative to each other; by example using a cylinder mounted between the two amounts. In the two solutions proposed, the leaf forms a sort of staple which connects the two uprights of the frame and thus increases the rigidity of the latter in closed position of the door.

La fente selon l'invention peut par exemple être délimitée latéralement par deux surfaces parallèles, c'est-à-dire définir un canal à section en "U". Afin d'augmenter d'avantage le caractère anti-effraction de la porte, ladite fente présente avantageusement une section de passage étroite suivie, en direction de pénétration de l'élément en saillie, d'un élargissement unilatéral. Pour une porte anti-effraction conçue pour résister à une effraction à partir de la face charnières, il s'agit d'un élargissement unilatéral en direction du vantail. Pour une porte anti-effraction conçue pour résister à une effraction à partir de la face opposée aux charnières, il s'agit d'un élargissement unilatéral en direction du chambranle. Dans les deux cas une poussée importante sur l'extrémité de la bande métallique en saillie déforme cette dernière, de sorte qu'elle pénètre dans l'élargissement de la fente et s'accroche dans cette dernière. En voulant forcer de cette façon le joint on a comme résultat d'ancrer le côté du vantail muni du dispositif de verrouillage davantage dans le chambranle. Il sera apprécié que l'élément délimitant la fente du côté dudit élargissement, qui forme une sorte de crochet derrière lequel l'élément en saillie déformé vient se replier, n'est pas accessible du côté duquel l'effraction a lieu. Cet élément est en effet soit recouvert par le vantail, soit recouvert par le chambranle.The slot according to the invention can for example be delimited laterally by two parallel surfaces, i.e. define a channel section in "U". In order to increase more the burglar-proof nature of the door, said slot advantageously has a passage section closely followed, in the direction of penetration of the element in protrusion, unilateral enlargement. For a door burglar resistant designed to withstand burglary from the hinge side, this is a widening unilateral towards the leaf. For a burglar-proof door designed to resist break-in from on the side opposite the hinges, it is a unilateral widening in the direction of the jamb. In both cases a significant push on the end of the protruding metal strip deforms the latter, so that it enters the widening of the slot and clings to it. By wanting to force this so the joint results in anchoring the side of the leaf with locking device further in the doorframe. It will be appreciated that the element delimiting the slot on the side of said enlargement, which forms a sort of hook behind which the deformed projecting element comes fall back, is not accessible from the side the break-in takes place. This element is indeed either covered by the leaf, or covered by the jamb.

La fente est avantageusement définie par un élément rapporté sur le chambranle. Il s'agit par exemple d'un profilé en "U", dont une première branche est munie d'un rebord orienté vers la deuxième branche, de façon à définir pour l'élément en saillie une section de passage étroite entre le rebord de la première branche et la deuxième branche. Il est bien entendu aussi possible d'intégrer, par exemple d'usiner ou de former, la fente directement dans le chambranle, respectivement dans le vantail.The slot is advantageously defined by an element reported on the jamb. This is for example a "U" shaped profile, a first branch of which is provided with a rim oriented towards the second branch, so as to define for the protruding element a narrow passage section between the edge of the first branch and the second plugged. It is of course also possible to integrate, by example of machining or forming, the slot directly in the jamb, respectively in the leaf.

Reste à noter que la présente invention pourrait naturellement aussi être appliquée à une fenêtre, dont le châssis doit présenter une résistance élevée à une effraction à l'aide d'un levier. Il n'est pas non plus exclu de l'appliquer à une porte d'un coffre.It should be noted that the present invention could naturally also be applied to a window, the chassis must have a high resistance to break-in using a lever. Nor is it excluded from applying it to a door of a chest.

  • la Figure 2A représente un détail d'une variante d'exécution de la porte de la Figure 2.
Other advantages and characteristics of the present invention will result from the detailed description of preferred embodiments, given below by way of example, based on the appended figures, in which:
  • Figure 1 shows a partial section through a burglar-proof door designed to resist burglary from the hinge side;
  • Figure 1A shows a detail of an alternative embodiment of Figure 1;
  • Figure 2 shows a partial section through a burglar-proof door designed to resist burglary from the face opposite the hinges;
  • Figure 2A shows a detail of an alternative embodiment of the door of Figure 2.

La Figure 1 montre une coupe transversale partielle à travers une porte anti-effraction selon l'invention, conçue pour être exposée à une effraction à partir de la face charnières, c'est-à-dire dans le sens de la flèche 12. Cette porte 10 comprend un chambranle ou dormant 14 et une feuille de porte ou vantail 16.Figure 1 shows a partial cross section at through an anti-intrusion door according to the invention, designed to be exposed to break-in from the face hinges, i.e. in the direction of arrow 12. This door 10 includes a frame or a frame 14 and a door leaf or leaf 16.

Le chambranle 14 est solidement ancré dans une ouverture d'une paroi, par exemple une baie dans un mur. Pour augmenter son résistance à une effraction le chambranle est avantageusement rempli d'un béton céramique 18.The jamb 14 is firmly anchored in a opening of a wall, for example a bay in a wall. To increase its resistance to burglary frame is advantageously filled with ceramic concrete 18.

Le vantail comprend généralement une ossature 20, supportant un remplissage 22, ainsi que des tôles de couverture 24 et 26 de chaque face du vantail 16. De façon connue, le vantail est articulé d'un côté sur le chambranle 14 et muni du côté opposé d'un dispositif de verrouillage.The leaf generally comprises a frame 20, supporting a filling 22, as well as sheets of cover 24 and 26 on each side of the leaf 16. So known, the leaf is hinged on one side on the frame 14 and provided on the opposite side with a locking device.

Sur la Figure 1 on voit le côté du vantail 16 qui est muni du dispositif de verrouillage (non montré). Il s'agit le plus souvent d'une ou de plusieurs serrures, munies chacune d'un pêne lançant et/ou dormant, qui s'engage dans une gâche solidaire du chambranle 14. Ce dispositif de verrouillage tient fermée la porte 10 et résiste à un effort de traction, plus ou moins important, exercé sur le vantail 16 dans le sens de l'ouverture de la porte 10.In Figure 1 we see the side of leaf 16 which is fitted with the locking device (not shown). It's about usually one or more locks, provided each of a bolt throwing and / or dormant, which engages in a keeper integral with the jamb 14. This device lock keeps door 10 closed and resists more or less significant tensile force exerted on the leaf 16 in the direction of door 10 opening.

La partie du vantail 16, dans lequel sont logées la ou les serrures, est avantageusement protégée, du côté exposé à l'effraction, de préférence sur la toute la hauteur de la porte, par un bandeau de protection 28 rapporté sur le vantail 16 proprement dit. Il s'agit par exemple d'une structure métallique soudée sur le vantail 16 et munie de préférence d'un remplissage céramique 30 ou d'un remplissage équivalent, qui présente une bonne résistance à un outil coupant, telle qu'une foreuse ou une tronçonneuse. Ce bandeau dépasse latéralement le vantail 16 proprement dit, de façon à recouvrir un premier joint 32 entre le chambranle 14 et le vantail 16. Avec le chambranle 14 le bandeau 28 forme lui-même un deuxième joint 34. Du côté de ce joint 34 le bandeau 28 est bordé latéralement sur toute sa longueur par une bande métallique 35 qui forme un rebord 36 dépassant en saillie du côté du chambranle 14. Il sera noté que le rebord 36 est de préférence perpendiculaire au plan médian du vantail 16. En absence du bandeau 28, la bande métallique 35 pourrait bien entendu aussi être directement rapportée sur le chant du vantail 16 ou être formée par une tôle de ce dernier.The part of leaf 16, in which are housed the the locks, is advantageously protected, on the exposed side break-in, preferably over the entire height of the door, by a protective strip 28 attached to the leaf 16 proper. This is for example a welded metal structure on leaf 16 and provided with preferably a ceramic filling 30 or a equivalent filling, which has good resistance to a cutting tool, such as a drill or a chainsaw. This strip laterally projects the leaf 16 properly said, so as to cover a first joint 32 between the frame 14 and leaf 16. With frame 14 the strip 28 itself forms a second seal 34. On the side of this joint 34 the strip 28 is bordered laterally on all its length by a metal strip 35 which forms a rim 36 protruding from the side of the jamb 14. It will note that the rim 36 is preferably perpendicular to the leaf mid-plane 16. In the absence of the strip 28, the metal strip 35 could of course also be directly attached to the edge of the leaf 16 or be formed by a sheet of the latter.

Le chambranle 14 est muni d'une fente 38, qui est agencée sur le chambranle 14, dans le prolongement du joint 34, de façon que le rebord 36 puisse y pénétrer lors de la fermeture de la porte 10. Sur la Figure 1 le joint 34 a, jusqu'à l'entrée de la fente 38, une profondeur qui est environ égale à quatre fois sa largeur.The jamb 14 is provided with a slot 38, which is arranged on the frame 14, in the extension of the joint 34, so that the rim 36 can enter there during the door 10 closes. In FIG. 1, the gasket 34 a, up to the entrance of slot 38, a depth which is about four times its width.

La fente 38 est par exemple délimitée latéralement par deux surfaces parallèles 40 et 42, tel que montré sur la Figure 1A. La largeur de la fente est de préférence inférieure à la profondeur de pénétration de la bande métallique 35 dans celle-ci. Dans une exécution préférentielle, la fente 38 a une section telle que représentée sur la Figure 1, c'est-à-dire qu'elle présente une section de passage étroite 44 comme section d'entrée pour le rebord 36, suivie d'un élargissement unilatéral 43 en direction du vantail 16. Dans ce cas la largeur de cette section d'entrée est de préférence inférieure à la profondeur de pénétration de la bande métallique 35 dans celle-ci. Sur la Figure 1 la fente 38 est par exemple délimitée du côté du vantail 16 par une tôle métallique 46, dont un rebord 48, orienté vers la surface 49 qui délimite la fente 38 du côté opposé, définit ladite section de passage minimale 44. La section transversale de la tôle 46 munie de son rebord 48 a la forme d'un crochet. La fente 38 peut être réalisée (p. ex. usinée ou formée) directement dans le chambranle 14 ou être réalisée à l'aide d'une pièce rapportée. Sur la Figure 1 il s'agit par exemple d'un profilé en "U", dont une des deux branches définit le rebord 48, qui est fixé sur le chambranle 14. Il importe de souligner que l'élément qui définit la fente 38 du côté du vantail 16 n'est pas accessible du côté de la porte exposé à l'effraction.The slot 38 is for example delimited laterally by two parallel surfaces 40 and 42, as shown on the Figure 1A. The width of the slot is preferably less than the penetration depth of the strip metallic 35 therein. In an execution preferential, the slot 38 has a section such that shown in Figure 1, i.e. it has a narrow passage section 44 as an entry section for edge 36, followed by unilateral widening 43 in the direction of leaf 16. In this case the width of this input section is preferably less than the penetration depth of the metal strip 35 into this one. In Figure 1 the slot 38 is for example delimited on the side of the leaf 16 by a metal sheet 46, including a rim 48, oriented towards the surface 49 which delimits the slot 38 on the opposite side defines said section of minimum passage 44. The cross section of the sheet 46 provided with its rim 48 has the shape of a hook. Slot 38 can be produced (e.g. machined or formed) directly in the frame 14 or be made using a part reported. In Figure 1 it is for example a "U" shaped profile, one of the two branches of which defines the ledge 48, which is fixed on the jamb 14. It is important to point out that the element that defines the slot 38 on the side of the leaf 16 is not accessible from the exposed door side breaking and entering.

Lorsqu'on cherche à forcer la porte 10 à l'aide d'un levier (par exemple un pied-de-biche), une pointe de ce dernier est introduite à travers ledit deuxième joint 34 entre le chambranle 14 et le vantail 16. Grâce au rebord métallique 36, qui prolonge sans discontinuité de surface le chant 50 du bandeau 28 dans la fente 38, on ne trouve sur le vantail 16 plus aucun appui adéquat, qui permettrait de transmettre à ce dernier un effort ayant une importante composante en direction de l'ouverture de la porte 10. Bien entendu la surface 52 opposée du chambranle 14 ne présente pas non plus de discontinuité pouvant servir de point d'appui à un levier. Même si on arrive à pénétrer avec la pointe d'un levier dans la fente 38, pour exercer sur la tôle 36 une pression importante, on n'arrive pas non plus à créer un point d'appui pour la pointe du levier qui permettrait d'exercer une force importante en direction de l'ouverture de la porte 10. En effet, dans le cas de la Figure 1A une pression exercée sur l'extrémité libre du rebord 36 applique ce dernier fortement contre la surface 42. L'effort du levier est par conséquent transmis au chambranle 14, sans que soit créé un effort important perpendiculairement au vantail 16. Dans le cas de la Figure 1 la pression exercée sur le rebord 36 replie ce dernier dans l'élargissement 43 vers le vantail 16 et l'accroche ainsi derrière le rebord 48 pour créer un ancrage supplémentaire du vantail 16 dans son chambranle 14. L'ancrage ainsi créé s'oppose à tout déplacement du vantail 16 dans le sens de l'ouverture de la porte 10. Il sera aussi apprécié qu'il est quasi impossible d'augmenter sensiblement la largeur dudit deuxième joint 34 entre le chambranle et bandeau 28, vu que ce dernier est ancré, dès fermeture de la porte, à l'aide du rebord 36 dans le chambranle 14.When we try to force door 10 with a lever (for example a crowbar), a point of this the latter is introduced through said second seal 34 between the frame 14 and the leaf 16. Thanks to the flange metallic 36, which continuously extends the surface the edge 50 of the strip 28 in the slot 38, we do not find on leaf 16 plus no adequate support, which would allow to transmit to the latter an effort having an important component towards the opening of door 10. Good heard the opposite surface 52 of the frame 14 does not also no discontinuity that can serve as a point to support a lever. Even if we manage to penetrate with the tip of a lever in the slot 38, to exert on the sheet 36 an important pressure, one does not arrive either create a fulcrum for the tip of the lever which would exert significant force towards the opening of door 10. Indeed, in the case of Figure 1A pressure exerted on the free end of the ledge 36 applies the latter strongly against the surface 42. The leverage is therefore transmitted to the frame 14, without significant effort being created perpendicular to leaf 16. In the case of Figure 1 the pressure exerted on the rim 36 folds the latter in the widening 43 towards the leaf 16 and the hook so behind ledge 48 to create an anchor additional leaf 16 in its frame 14. The anchor thus created opposes any movement of the leaf 16 in the direction of opening door 10. It will also appreciated that it is almost impossible to increase substantially the width of said second seal 34 between the jamb and strip 28, since the latter is anchored, from closing the door, using the edge 36 in the jamb 14.

Il est encore intéressant de noter qu'un libre accès latéral à toute l'épaisseur du chant latéral 50 du bandeau 28, ainsi qu'au rebord 36, est avantageusement empêché par une surface 52 du chambranle qui fait face au chant 50 et au rebord métallique 36 de façon à définir le joint 34. De cette façon on empêche, en position fermée de la porte, efficacement le forage de trous latéraux dans le bandeau 28, respectivement le rebord 36. De tels trous latéraux permettraient en effet de trouver l'appui recherché pour un levier. On invite de même l'utilisation d'une tronçonneuse pour couper éventuellement une ouverture dans le rebord 36 à l'endroit repéré par la flèche 54, ce qui permettrait aussi de trouver l'appui recherché pour un levier.It is still interesting to note that free access lateral to the entire thickness of the lateral edge 50 of the strip 28, as well as at edge 36, is advantageously prevented by a surface 52 of the frame which faces the edge 50 and to the metal rim 36 so as to define the seal 34. From this way we prevent, in the closed position of the door, effectively drilling lateral holes in the strip 28, respectively the rim 36. Such lateral holes would indeed find the support sought for a the sink. We also invite the use of a chainsaw to possibly cut an opening in the rim 36 at the location marked by arrow 54, which would allow also to find the support sought for a lever.

La Figure 2 représente une coupe à travers une porte anti-effraction 110 selon l'invention, conçue pour être exposée à une effraction à partir de la face opposée aux charnières, c'est-à-dire dans le sens de la flèche 112. Elle comprend un chambranle ou dormant 114 et une feuille de porte ou vantail 116.Figure 2 shows a section through a door burglar-proof 110 according to the invention, designed to be exposed to break-in from the face opposite hinges, i.e. in the direction of arrow 112. It includes a frame or sleeping frame 114 and a sheet door or leaf 116.

De même que sur la Figure 1, on voit le chant du vantail 116 qui est muni d'un dispositif de verrouillage (non montré). Ce dernier s'oppose notamment à un effort de poussée, plus ou moins important, exercé à partir de la face opposée aux charnières sur le vantail 116 en direction de l'ouverture de la porte 110.As in Figure 1, we see the song of the leaf 116 which is fitted with a locking device (not shown). The latter notably opposes an effort to more or less significant thrust exerted from the opposite side of hinges on leaf 116 towards from the opening of door 110.

Une fente 138 orientée vers le chambranle 114 s'étend dans le vantail 116 le long du chant muni du dispositif de verrouillage. Comme dans le cas de la Figure 1A, cette fente 138 peut être limitée latéralement par deux surfaces parallèles 140, 142, tel que montré sur la Figure 2A. De préférence la fente 138 aura cependant une section telle que représentée sur la Figure 2, c'est-à-dire qu'elle présente une section de passage étroite 144 comme section d'entrée, suivie d'un élargissement unilatéral 143 en direction du vantail 116. Sur la Figure 2 la fente 138 est par exemple délimitée du côté du chambranle 114 par une tôle métallique 146 dont un rebord 148, qui est orienté vers la surface 149 délimitant la fente 138 du côté opposé, définit ladite section de passage minimale 144. Cette fente 138 peut être réalisée directement dans le vantail 136 ou être réalisée dans une pièce rapportée. Sur la Figure 2 il s'agit par exemple d'un profilé en "U", dont une des deux branches définit le rebord 48. Ce profilé en "U" est intégré dans le vantail 116. Il sera noté que la branche qui définit le rebord 48 est non-accessible du côté de la porte 110 exposé à l'effraction.A slot 138 oriented towards the frame 114 extends in the leaf 116 along the edge provided with the device for locking. As in the case of Figure 1A, this slot 138 can be limited laterally by two surfaces parallels 140, 142, as shown in Figure 2A. Of preferably the slot 138 will however have a section such as shown in Figure 2, i.e. it has a narrow passage section 144 as a section entry, followed by unilateral enlargement 143 in leaf 116 direction. In Figure 2 the slot 138 is for example delimited on the side of the frame 114 by a sheet metal 146 including a flange 148, which is oriented towards the surface 149 delimiting the slot 138 on the opposite side, defines said minimum passage section 144. This slot 138 can be carried out directly in the leaf 136 or be performed in an insert. In Figure 2 there it is for example a "U" profile, one of the two branches defines edge 48. This "U" profile is integrated in leaf 116. It will be noted that the branch which defines the edge 48 is not accessible from the side of the door 110 exposed to break-in.

Le chambranle 114 est bordé latéralement par une bande métallique plane 138 qui dépasse en saillie de façon à être reçue dans la fente 138 lors de la fermeture de la porte 110. Il s'agit par exemple d'un rebord du chambranle qui est perpendiculaire au plan de la porte 110. Il importe de souligner que du côté exposé à l'effraction le chambranle 114 et le rebord 136 présentent une surface plane 152 sans discontinuités, qui pourraient éventuellement servir de point d'appui pour exercer à l'aide d'un levier une poussée sur le vantail 116.The frame 114 is bordered laterally by a strip flat metallic 138 which protrudes so as to be received in slot 138 when the door is closed 110. For example, it is an edge of the doorframe which is perpendicular to the plane of door 110. It is important to point out that on the side exposed to break-in the doorframe 114 and the flange 136 have a flat surface 152 without discontinuities, which could possibly serve as fulcrum to push with a lever on the leaf 116.

Le rebord 136 du chambranle 114 empêche efficacement l'introduction de la pointe d'un levier dans le joint 134 entre le vantail 116 et le chambranle 114. Si tel n'était pas le cas, on pourrait effectivement exercer à l'aide d'un levier une importante pression sur le vantail 116 dans la direction d'ouverture de la porte 110. Or, une telle sollicitation de la porte 110 mettrait rapidement en péril sa tenue à l'effraction, car c'est essentiellement le dispositif de verrouillage, le plus souvent le pêne d'une serrure, qui doit reprendre cet effort perpendiculaire au vantail 116. Il est en effet bien connu que la serrure est, dans la majorité des cas, l'élément présentant la résistance mécanique la plus faible du système chambranle 114 / vantail 116.The flange 136 of the frame 114 effectively prevents the introduction of the point of a lever into the joint 134 between leaf 116 and jamb 114. If it were not not the case we could actually exercise using a lever a significant pressure on the leaf 116 in the opening direction of door 110. However, such pressing door 110 would quickly jeopardize its resistance to break-in, because it is essentially the locking device, most often the bolt of a lock, which must resume this effort perpendicular to the leaf 116. It is indeed well known that the lock is, in the majority of cases, the element presenting the lowest mechanical resistance of the frame system 114 / leaf 116.

Si on réussit à prendre appui avec un levier sur la surface 152 du chambranle et à pénétrer avec la pointe du levier dans la fente 138, pour exercer ainsi une importante force de poussée sur la surface 140 respectivement 149, on arrive peut-être à déplacer légèrement le vantail 116, dû au jeu dans les charnières. Mais le vantail 116 vient rapidement buter avec sa surface 142, respectivement le rebord 148 contre le rebord 136 du chambranle 114. Il s'ensuit qu'une sollicitation de ce genre ne doit plus être reprise entièrement par les charnières du vantail 116.If we manage to take support with a lever on the surface 152 of the jamb and to penetrate with the tip of the lever in slot 138, thereby exerting an important thrust force on the surface 140 respectively 149, we may be able to slightly move leaf 116, due to play in the hinges. But leaf 116 comes quickly abut with its surface 142, respectively the ledge 148 against ledge 136 of the frame 114. It it follows that such solicitation should no longer be taken up entirely by the hinges of the leaf 116.

Même en introduisant la pointe d'un levier dans la fente 138 et en prenant appui d'un côté sur le vantail 116 et de l'autre côté sur l'extrémité libre du rebord 136, on n'arrive pas à affaiblir de façon sensible la résistance à l'effraction de la porte 110. En effet, dans le cas de la Figure 2A le rebord 136 est pressé contre la surface 140, et dans le cas de la Figure 2, le rebord 136 est replié dans ledit élargissement 143 de la fente 138 et ancre ainsi ce bord du vantail 114 encore plus solidement dans le chambranle 114.Even by inserting the tip of a lever into the slot 138 and taking support on one side on leaf 116 and on the other side on the free end of the flange 136, we fails to significantly weaken resistance to breaking door 110. Indeed, in the case of FIG. 2A the rim 136 is pressed against the surface 140, and in the case of Figure 2, the flange 136 is folded in said widening 143 of slot 138 and thus anchors this edge of leaf 114 even more solidly in the frame 114.
