Description

L'invention concerne, de façon générale, un dispositif d'obturation d'une ouverture, comprenant un cadre et un panneau articulé, du type de ceux qui constituent des équipements de voirie donnant par exemple accès à des regards enterrés dans le sol.The invention relates, in general, to a shutter device of an opening, comprising a frame and an articulated panel, of the type of those which constitute road equipment giving for example access to manholes buried in the ground.

Plus précisément, l'invention concerne un dispositif d'obturation d'une ouverture, comprenant un cadre bordant l'ouverture et présentant un rebord et une feuillure, un panneau présentant une face externe, une face interne et une épaisseur, ce panneau étant amovible par rapport au cadre et monté à rotation sur le cadre entre une position d'ouverture dans laquelle il est dressé et donne accès à l'ouverture, et une position de fermeture dans laquelle il est couché et s'inscrit en épaisseur dans le rebord pour s'appliquer au moins partiellement sur une face supérieure de la feuillure et obturer l'ouverture, et des organes d'articulation comprenant au moins un oeil d'articulation adjacent à un bord d'articulation du panneau et débouchant au moins sur l'épaisseur du panneau, et un axe d'articulation solidaire d'un bord d'articulation du cadre, s'étendant au-dessus de la feuillure parallèlement au rebord et à la feuillure, et sélectivement engagé dans l'oeil d'articulation par rapprochement réciproque du panneau en position ouverte et du cadre.More specifically, the invention relates to a closure device of an opening, comprising a frame bordering the opening and having a flange and a rabbet, a panel having an outer face, an inner face and a thickness, this panel being removable relative to the frame and rotatably mounted on the frame between an open position in which it is erected and gives access to the opening, and a closed position in which it is laid down and fits in thickness in the flange for apply at least partially to an upper face of the rabbet and seal the opening, and articulation members comprising at least one hinge eye adjacent to a hinge edge of the panel and opening at least on the thickness of the panel, and a hinge axis integral with a hinge edge of the frame, extending above the rabbet parallel to the rim and the rabbet, and selectively engaged in the eye of articulati one reciprocal approach of the panel in the open position and the frame.

Des dispositifs de ce type sont connus depuis longtemps et un exemple en est donné par le document de brevet FR-A- 2 519 665 ( EP-A-0084510 ).Devices of this type have been known for a long time and an example is given by the document of FR-A-2 519 665 ( EP-A-0084510 ).

Dans leur application privilégiée, ces dispositifs permettent d'interdire l'accès à toutes sortes de locaux techniques dans lesquels des personnes non autorisées peuvent chercher à s'introduire pour les motifs délictueux les plus divers.In their privileged application, these devices make it possible to prohibit access to all kinds of technical premises in which unauthorized persons may seek to break in for various criminal offenses.

Alors qu'il est crucial, dans ces conditions, de sécuriser au maximum l'accès contrôlé par ces dispositifs, certains des dispositifs connus de ce type peuvent éventuellement être fracturés par un sectionnement de l'axe d'articulation qui sert à retenir le panneau au cadre.While it is crucial, under these conditions, to secure the maximum access controlled by these devices, some of the known devices of this type may possibly be fractured by a cutting of the hinge pin which is used to hold the panel to the frame.

Dans ce contexte, la présente invention a pour but de proposer un dispositif d'obturation à panneau amovible articulé capable de résister aux tentatives d'effraction qui consistent à scier l'axe d'articulation.In this context, the purpose of the present invention is to provide an articulated removable panel closure device capable of resisting burglary attempts which consist in sawing the hinge pin.

A cette fin, le dispositif de l'invention, par ailleurs conforme à la définition générique qu'en donne le préambule ci-dessus, est essentiellement caractérisé en ce qu'il comprend une clavette solidaire du panneau et dont une première extrémité se trouve, pour la position fermée du panneau, insérée sous une face inférieure d'une partie formant gâche de la feuillure du bord d'articulation du cadre.To this end, the device of the invention, furthermore in conformity with the generic definition given in the preamble above, is essentially characterized in that it comprises a key secured to the panel and of which a first end is located, for the closed position of the panel, inserted under a lower face of a striker portion of the rabbet of the hinge edge of the frame.

De préférence, la clavette est rendue solidaire du panneau de façon amovible.Preferably, the key is secured to the panel removably.

La clavette peut notamment être rendue solidaire d'un premier voile qui est porté par le panneau et qui est sensiblement parallèle au rebord que forme le cadre sur son bord d'articulation .The key can in particular be made integral with a first web which is carried by the panel and which is substantially parallel to the flange that forms the frame on its hinge edge.

Par exemple, il est possible de prévoir que la clavette présente une seconde extrémité distante de sa première extrémité, que le premier voile du panneau présente un perçage dans lequel la clavette est engagée par sa seconde extrémité jusqu'à rencontrer une butée, que les première et seconde extrémités de la clavette soient disposées de part et d'autre du premier voile, et que la seconde extrémité de la clavette reçoive un organe de blocage amovible transversal, tel qu'une vis ou une goupille, qui rend la clavette prisonnière entre la butée et le premier voile.For example, it is possible to provide that the key has a second end remote from its first end, the first web of the panel has a bore in which the key is engaged by its second end to meet a stop, that the first and second ends of the key are disposed on either side of the first web, and that the second end of the key receives a transverse removable locking member, such as a screw or a pin, which makes the key trapped between the stop and the first veil.

La clavette est avantageusement recourbée à sa première extrémité, notamment pour faciliter sa manipulation.The key is advantageously bent at its first end, in particular to facilitate handling.

L'axe d'articulation n'a pas besoin d'être continu mais peut présenter au moins une première extrémité libre et une première extrémité liée, la première extrémité liée de l'axe étant par exemple portée par une paroi du cadre qui est perpendiculaire au rebord et à la feuillure et qui les relie l'un à l'autre.The hinge axis does not need to be continuous but may have at least one free end and a first end connected, the first end linked to the axis being for example carried by a wall of the frame which is perpendicular to the flange and the rabbet and which connects them to one another.

L'oeil d'articulation peut être traversant et déboucher sur l'épaisseur du panneau à travers un premier guide permettant le passage de l'axe d'articulation.The hinge eye can be through and lead to the thickness of the panel through a first guide allowing the passage of the hinge axis.

Cependant, l'oeil d'articulation peut aussi être borgne, être creusé dans un second voile du panneau, qui s'étend perpendiculairement à l'axe, et déboucher sur la face interne du panneau à travers un second guide permettant le passage de l'axe d'articulation en position de fermeture du panneau.However, the hinge eye can also be blind, be hollowed into a second web of the panel, which extends perpendicular to the axis, and lead to the inner face of the panel through a second guide allowing the passage of the hinge pin in the closed position of the panel.

La mise en oeuvre du dispositif de l'invention peut être rendue plus aisée en prévoyant que la feuillure s'étende en majeure partie dans un plan d'appui et qu'elle présente un décrochement grâce auquel sa partie formant gâche est surélevée en direction de l'axe d'articulation par rapport au plan d'appui.The implementation of the device of the invention can be made easier by providing that the rabbet extends for the most part in a bearing plane and that it has a recess with which its striker portion is raised in the direction of the axis of articulation relative to the support plane.

Comme annoncé précédemment, l'invention concerne un dispositif permettant d'obturer une ouverture O (figure 2), et comprenant essentiellement un cadre 1 bordant l'ouverture et un panneau 2, amovible par rapport au cadre 1 et sélectivement monté sur ce dernier.As previously announced, the invention relates to a device for closing an opening O ( figure 2 ), and essentially comprising a frame 1 bordering the opening and a panel 2, removable relative to the frame 1 and selectively mounted thereon.

Plus précisément, le panneau 2 est monté sur le cadre 1 à rotation entre une position d'ouverture (figure 6) dans laquelle il est dressé et donne accès à l'ouverture O, et une position de fermeture (figures 4, 5, 9, 10) dans laquelle il est sensiblement horizontal et obture l'ouverture O.More specifically, the panel 2 is mounted on the frame 1 rotated between an open position ( figure 6 ) in which it is erected and gives access to the opening O, and a closed position ( Figures 4, 5 , 9 , 10 ) in which it is substantially horizontal and closes the opening O.

Ce panneau 2, qui présente (figure 4) une face externe 21 sensiblement plane, une face interne 22 et une épaisseur 23, s'applique, au moins par endroits, sur la face supérieure 121 de la feuillure 12 du cadre 1 dans sa position de fermeture, tout en s'inscrivant, en épaisseur, dans le rebord 11 de ce cadre.This panel 2, which presents figure 4 ) a substantially flat outer face 21, an inner face 22 and a thickness 23, is applied, at least in places, on the upper face 121 of the rabbet 12 of the frame 1 in its closed position, while registering, in thickness, in the rim 11 of this frame.

Le panneau 2 est monté à rotation sur la cadre 1 au moyen d'organes d'articulation qui comprennent un oeil d'articulation 3 défini sur le panneau, et un axe d'articulation 4 solidaire du cadre 1 et engagé dans l'oeil d'articulation 4 par rapprochement réciproque du panneau 2 en position ouverte et du cadre 1.The panel 2 is rotatably mounted on the frame 1 by means of hinge members which comprise a hinge eye 3 defined on the panel, and a hinge pin 4 integral with the frame 1 and engaged in the eye articulation 4 by mutual reciprocation of the panel 2 in the open position and the frame 1.

Dans le cas où le dispositif est sécurisé, une serrure (non représentée) est traditionnellement prévue sur un bord du cadre opposé au bord d'articulation du cadre, c'est-à-dire sur un bord du cadre opposé à celui qui porte l'axe d'articulation 4 et qui est notamment visible sur la figure 1, cette serrure permettant, en coopération avec l'axe 4, de rendre le panneau solidaire du cadre.In the case where the device is secure, a lock (not shown) is traditionally provided on an edge of the frame opposite to the hinge edge of the frame, that is to say on an edge of the frame opposite to that which carries the door. articulation axis 4 and which is particularly visible on the figure 1 , this lock allowing, in cooperation with the axis 4, to make the panel integral with the frame.

Cependant, même dans le cas où la serrure ainsi prévue est difficile à fracturer, une technique d'effraction possible des dispositifs connus consiste à passer une scie à métaux entre le panneau 2 et la cadre 1 pour scier l'axe d'articulation 4, puis à faire pivoter le panneau 2 autour de la serrure pour le dégager du cadre 1.However, even in the case where the lock thus provided is difficult to break, a possible break-in technique of the known devices consists of passing a hacksaw between the panel 2 and the frame 1 to saw the hinge pin 4, then rotate the panel 2 around the lock to release it from the frame 1.

Le dispositif de l'invention rend impossible ce type d'effraction.
Selon l'invention (figure 5), le dispositif comprend une clavette 5 qui est solidaire du panneau 2, et dont une extrémité formant pêne 51 se trouve insérée, pour la position fermée du panneau 2, sous la face inférieure 122 d'une partie 120 de la feuillure 12, qui forme gâche, sur le bord d'articulation du cadre.The device of the invention makes this type of break-in impossible.
According to the invention ( figure 5 ), the device comprises a key 5 which is integral with the panel 2, and a end of the bolt 51 is inserted, for the closed position of the panel 2, under the lower face 122 of a portion 120 of the rabbet 12, which forms a striker, on the hinge edge of the frame.

Ainsi, même en cas de sectionnement de l'axe 4, il est impossible de faire pivoter le panneau 2 autour de la serrure, ce panneau restant prisonnier du cadre par le fait que la clavette 5 est retenue par la partie 120 de la feuillure 12.Thus, even if cutting the axis 4, it is impossible to rotate the panel 2 around the lock, this panel remaining prisoner of the frame in that the key 5 is retained by the portion 120 of the rabbet 12 .

L'invention s'applique en particulier au cas où l'axe 4 n'est pas continu, mais est par exemple formé de deux pions en vis-à-vis, tels que le pion 40 visible à la figure 1.The invention applies in particular to the case where the axis 4 is not continuous, but is for example formed of two pawns vis-à-vis, such as the pin 40 visible at the figure 1 .

Comme le montre notamment la figure 5, l'extrémité formant pêne 51 de la clavette 5 peut être recourbée, ce qui facilite la manipulation de cette clavette.As shown in particular figure 5 , the bolt end 51 of the key 5 can be bent, which facilitates the manipulation of this key.

Dans le mode de réalisation de l'invention qui offre le plus d'avantages, la clavette 5 est rendue solidaire du panneau 2 de façon amovible.In the embodiment of the invention that offers the most advantages, the key 5 is secured to the panel 2 removably.

Comme le montrent les figures 5 à 7 et 10 à 11, la clavette 5 est par exemple rendue solidaire d'un voile 25 du panneau 2, qui est également visible sur les figures 2 et 3 et qui est sensiblement parallèle au rebord 11 du cadre 1 adjacent à l'axe d'articulation 4.As shown by Figures 5 to 7 and 10 to 11 , the key 5 is for example made integral with a web 25 of the panel 2, which is also visible on the Figures 2 and 3 and which is substantially parallel to the flange 11 of the frame 1 adjacent to the hinge axis 4.

Pour assurer un montage aisé et efficace de la clavette 5, le voile 25 peut présenter un perçage 250 dans laquelle cette clavette est engagée à volonté, par son extrémité 52 opposée à l'extrémité 51 formant pêne, jusqu'à rencontrer une butée 6 par exemple prévue sur le panneau 2.To ensure easy and effective mounting of the key 5, the web 25 may have a bore 250 in which the key is engaged at will, by its end 52 opposite the end 51 forming a bolt, until a stop 6 by example provided on panel 2.

Dans la position de montage de la clavette 5, les extrémités 51 et 52 de celle-ci sont ainsi disposées de part et d'autre du voile 25.In the mounting position of the key 5, the ends 51 and 52 of the latter are thus disposed on either side of the web 25.

L'extrémité 52 de la clavette 5 peut alors recevoir une vis, une goupille, ou tout autre organe amovible similaire 7 assurant un blocage transversal de la clavette, et grâce auquel la clavette 5 est rendue prisonnière entre la butée 6 et le voile 25.The end 52 of the key 5 can then receive a screw, a pin, or any other similar removable member 7 providing a transverse locking of the key, and thanks to which the key 5 is trapped between the stop 6 and the web 25.

Dans le cas où l'axe d'articulation 4 est formé de deux pions en vis-à-vis tels que le pion 40, chaque pion présentant une extrémité libre telle que 41, et une extrémité liée telle que 42, cette dernière peut être portée par une paroi 13 du cadre 1, qui est perpendiculaire au rebord 11 et à la feuillure 12, et qui les relie l'un à l'autre comme le montre le mieux la figure 1.In the case where the hinge axis 4 is formed of two pions vis-à-vis such as the pin 40, each pin having a free end such as 41, and a bonded end such as 42, the latter may be carried by a wall 13 of the frame 1, which is perpendicular to the flange 11 and the rabbet 12, and which connects them to each other as best shown in FIG. figure 1 .

Comme le montrent les figures 2 à 11, l'oeil d'articulation 3 débouche sur l'épaisseur 23 du panneau 2 à travers un guide 31 qui permet le passage de l'axe d'articulation 4 en position d'ouverture du panneau 2, et donc le montage et le démontage de ce panneau dans cette position (figures 7 et 11).As shown by Figures 2 to 11 , the hinge eye 3 opens on the thickness 23 of the panel 2 through a guide 31 which allows the passage of the hinge pin 4 in the open position of the panel 2, and therefore the assembly and disassembly of this panel in this position ( figures 7 and 11 ).

Néanmoins, l'oeil d'articulation 3 peut aussi déboucher sur la face interne 22 du panneau 2 à travers un second guide 32 permettant le passage de l'axe d'articulation 4 en position de fermeture du panneau 2, et donc le montage et le démontage de ce panneau dans cette position (figure 8), pour autant que la clavette 5 soit amovible et ait été démontée préalablement.Nevertheless, the hinge eye 3 can also lead to the inner face 22 of the panel 2 through a second guide 32 allowing the passage of the hinge pin 4 in the closed position of the panel 2, and therefore the mounting and disassembly of this panel in this position ( figure 8 ), as long as the key 5 is removable and has been disassembled beforehand.

Dans ce dernier cas, l'oeil d'articulation 3 est borgne (figure 3), et il est creusé dans un voile 26 du panneau 2 qui s'étend perpendiculairement à l'axe 4.In the latter case, the hinge eye 3 is one-eyed ( figure 3 ), and is hollowed in a web 26 of the panel 2 which extends perpendicular to the axis 4.

Enfin, si la feuillure 12 s'étend en majeure partie dans un plan d'appui P (figure 1), elle présente de préférence un décrochement 129 grâce auquel sa partie formant gâche 120 est surélevée en direction de l'axe d'articulation 4 par rapport au plan d'appui P.Finally, if the rebate 12 extends for the most part in a support plane P ( figure 1 ), it preferably has a recess 129 with which its keeper portion 120 is raised towards the hinge axis 4 relative to the bearing plane P.
