Abstract

The manhole cover mounting has an opening (O) and a frame (1) with a lid (2) and a pivot axis (31) fixed to the frame. The pivot has a flat (310) and an eye (32) for articulation of the lid engaged in the pivot by a reduced section guide (320) which prevents the engagement of the eye in the pivot at set relative conditions of the lid and frame. The flat can have an angle greater than ninety degrees and the lid can only be fitted on the frame in a reversed position.

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 generally to a device for closing an opening, comprising a frame and an articulated panel, of the type 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, un panneau présentant une face externe sensiblement plane, 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 donne accès à l'ouverture, et une position de fermeture dans laquelle il s'inscrit en épaisseur dans un rebord du cadre pour s'appliquer sur une feuillure du cadre et obturer l'ouverture, et des organes d'articulation comprenant au moins un axe d'articulation solidaire d'un bord d'articulation du cadre et présentant un méplat en section transversale, et un oeil adjacent à un bord d'articulation du panneau, sélectivement engagé dans l'axe d'articulation par rapprochement réciproque du panneau en position ouverte et du cadre, et débouchant sur l'épaisseur du panneau à travers un guide de section réduite n'autorisant l'engagement de l'oeil dans l'axe d'articulation que suivant un angle d'inclinaison du panneau par rapport au cadre compris dans une plage déterminée d'angles d'inclinaison.More specifically, the invention relates to a device for closing an opening, comprising a frame bordering the opening, a panel with one side substantially planar external, an internal face and a thickness, this panel being removable relative to the frame and rotatably mounted on the frame between a position opening in which it gives access to the opening, and a closed position in which it fits thick in a rim of the frame to apply on a frame rebate and seal the opening, and articulation members comprising at least one axis of articulation secured to an edge of articulation of the frame and having a flat in cross section, and an eye adjacent to a hinge edge of the panel, selectively engaged in the axis of articulation by reciprocal approximation of the panel in the open position and the frame, and leading to the thickness of the panel to through a reduced section guide not authorizing the engagement of the eye in the axis of articulation that at an angle of inclination of the panel relative to the frame included in a determined range of angles of inclination.

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

Dans l'application privilégiée de tels dispositifs, les panneaux sont conçus pour résister à des charges importantes, en particulier lorsqu'ils sont installés sur la chaussée et qu'ils doivent donc résister au passages de véhicules automobiles, les panneaux étant donc à la fois massifs et relativement lourds.In the preferred application of such devices, panels are designed to withstand loads important, especially when installed on the pavement and therefore they must resist the passage of motor vehicles, the panels therefore being at the both massive and relatively heavy.

Dans ces conditions, la mise en place d'un panneau sur un dispositif de ce type s'avère difficile, voire dangereuse si le risque de fermeture intempestive du panneau est élevé.Under these conditions, the installation of a panel on a device of this type proves difficult, even dangerous if the risk of inadvertent closing of the panel is high.

Dans ce contexte, la présente invention a pour but de proposer un dispositif d'obturation à panneau amovible articulé, dont la mise en place soit relativement aisée en dépit du poids éventuellement important du panneau.In this context, the object of the present invention is to propose a shutter device with a removable panel articulated, whose installation is relatively easy despite the possibly heavy weight of the panel.

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 que le méplat de l'axe d'articulation a, par rapport au cadre, une inclinaison supérieure à un angle droit, et en ce que la plage déterminée d'angles d'inclinaison ne comprend que des angles d'inclinaison supérieurs à un angle droit, le panneau ne pouvant ainsi être monté sur le cadre que dans une position renversée.To this end, the device of the invention, by elsewhere conforms to the generic definition given by it the preamble above, is essentially characterized in that the flat of the articulation axis has, by relative to the frame, an inclination greater than an angle right, and in that the determined range of angles tilt only includes tilt angles greater than a right angle, the panel cannot be mounted on the frame only in an inverted position.

De préférence, le panneau comprend par ailleurs une rampe formée sur sa face externe, adjacente au bord d'articulation du panneau, et présentant au moins une surface de raccordement inclinée à la fois par rapport à la face externe et par rapport à l'épaisseur du panneau, pour guider le panneau le long du bord d'articulation du cadre en vue de l'engagement de l'axe d'articulation dans le guide de section réduite.Preferably, the panel also comprises a ramp formed on its external face, adjacent to the edge of articulation of the panel, and having at least one connection surface inclined both relative to the external face and relative to the thickness of the panel, to guide the panel along the hinge edge of the framework for engaging the hinge pin in the reduced section guide.

Dans un mode de réalisation particulier de l'invention, la rampe forme une surépaisseur sur la face externe du panneau.In a particular embodiment of the invention, the ramp forms an extra thickness on the face external of the panel.

Il peut être avantageux de faire en sorte que la feuillure du cadre présente, sur le bord d'articulation du cadre, une première came formée par une première surélévation de la feuillure, et que, dans sa position d'ouverture, le panneau soit en butée par une partie relativement externe de son épaisseur sur la première came, en butée par sa face externe sur le rebord du cadre, et en butée par l'oeil ou le guide de section réduite contre l'axe d'articulation.It may be beneficial to have the frame rebate present on the hinge edge of the frame, a first cam formed by a first elevation of the rebate, and that in its position opening, the panel is in abutment by a part relatively external of its thickness on the first cam, abutted by its external face on the edge of the frame, and in abutment by the eye or the section guide reduced against the hinge pin.

Il est également possible de prévoir que le panneau présente, sur son bord d'articulation, un talon faisant saillie d'une partie médiane de son épaisseur, que la première came soit terminée par un flanc abrupt dirigé vers la feuillure, que le talon chemine sur la première came lorsque le panneau passe de sa position de fermeture à sa position d'ouverture ou inversement, et que le talon tombe de la première came, en butée le long du flanc abrupt, lorsque le panneau atteint sa position d'ouverture, ce qui provoque un abaissement et un blocage du panneau empêchant toute fermeture intempestive.It is also possible to provide that the panel has a bead on its hinge edge protrusion of a middle part of its thickness, that the first cam is terminated by a steep flank directed towards the rebate, let the heel run on the first cam when the panel moves from its closed position in its open position or vice versa, and that the heel falls from the first cam, abutted along the side abrupt, when the panel reaches its position opening, causing a lowering and blocking of the panel preventing any untimely closing.

Dans ce cas, une fenêtre est avantageusement creusée dans le rebord du cadre, sur le bord d'articulation de ce cadre, pour permettre le passage du talon lors de la rotation du panneau entre sa position de fermeture et sa position d'ouverture.In this case, a window is advantageously carved into the edge of the frame, on the edge of articulation of this frame, to allow the passage of the heel when rotating the panel between its position closing and its open position.

La feuillure du cadre peut aussi présenter, sur le bord d'articulation du cadre, une seconde came formée par une seconde surélévation de la feuillure, une partie relativement interne de l'épaisseur du panneau pouvant ainsi cheminer sur cette seconde came lorsque le panneau passe de sa position de fermeture à sa position d'ouverture ou inversement, pour déplacer progressivement l'oeil et le guide de section réduite par rapport à l'axe d'articulation.The frame rebate may also have, on the hinge edge of the frame, a second cam formed by a second elevation of the rebate, part relatively internal the thickness of the panel can thus walk on this second cam when the panel goes from its closed position to its position opening or vice versa, to move gradually the eye and the guide of reduced section with respect to the axis hinge.

La feuillure du cadre peut encore présenter, sur le bord d'articulation du cadre, une troisième came formée par une troisième surélévation de la feuillure, le panneau présentant alors un pied qui, au moins dans la position de fermeture du panneau, s'appuie sur cette troisième came. The frame rebate may still show, on the hinge edge of the frame, a third cam formed by a third elevation of the rebate, the panel then presenting a foot which, at least in the panel closed position, relies on this third cam.

L'axe d'articulation présente par exemple une extrémité libre et une extrémité liée, et l'extrémité liée est portée par un voile perpendiculaire au rebord et à la feuillure du cadre et les reliant l'un à l'autre.The articulation axis has for example a free end and a tied end, and the end tied is carried by a veil perpendicular to the edge and at the frame rebate and connecting them to each other.

La mise en oeuvre du dispositif de l'invention peut être rendue plus aisée en prévoyant que le guide de section réduite débouche dans une partie de l'oeil qui est la plus éloignée de la face externe du panneau.The implementation of the device of the invention can be made easier by providing that the guide reduced section opens into a part of the eye which is furthest from the outside of the panel.

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 (Figures 5 et 6) dans laquelle il donne accès à l'ouverture O, et une position de fermeture (Figure 9) dans laquelle il obture l'ouverture O.More specifically, the panel 2 is mounted on the frame 1 rotating between an open position (Figures 5 and 6) in which it gives access to opening O, and a closed position (Figure 9) in which it closes the opening O.

Ce panneau 2, qui présente (Figure 2) une face externe 21 sensiblement plane, une face interne 22 et une épaisseur 23, s'applique, dans sa position de fermeture, sur une feuillure 12 du cadre 1 tout en s'inscrivant, en épaisseur, dans un rebord 11 de ce dernier.This panel 2, which has (Figure 2) a face outer 21 substantially planar, an inner face 22 and a thickness 23, applies, in its closed position, on a rebate 12 of frame 1 while registering, thickness, in a rim 11 of the latter.

Le panneau 2 est monté à rotation sur la cadre 1 au moyen d'organes d'articulation qui comprennent un axe d'articulation 31 solidaire du cadre 1, et un oeil d'articulation 32, sélectivement engagé dans l'axe d'articulation 31 par rapprochement réciproque du panneau 2 en position ouverte et du cadre 1. The panel 2 is rotatably mounted on the frame 1 at means of articulation organs which comprise an axis articulation 31 secured to the frame 1, and an eye hinge 32, selectively engaged in the axis hinge 31 by reciprocal approximation of the panel 2 in open position and frame 1.

L'axe d'articulation 31 est en fait solidaire d'un bord d'articulation 10 du cadre 1, et présente, en section transversale, un méplat 310.The articulation axis 31 is in fact integral with a hinge edge 10 of frame 1, and has, in cross section, a flat 310.

L'oeil d'articulation 32 est adjacent à un bord d'articulation 20 du panneau 2 et débouche sur l'épaisseur 23 du panneau à travers un guide de section réduite 320.The articulation eye 32 is adjacent to an edge hinge 20 of panel 2 and leads to the thickness 23 of the panel through a section guide reduced 320.

La section réduite du guide 320 a pour fonction de n'autoriser l'engagement de l'oeil 32 dans l'axe d'articulation 31 que lorsque le panneau 2 présente par rapport au cadre 1 un angle d'inclinaison A (Figure 2) compris dans une plage déterminée A0-A1 d'angles d'inclinaison, définie entre un angle minimal A0 (Figure 4) et un angle maximal A1 (Figure 5).The function of the reduced section of guide 320 is to allow the engagement of eye 32 in the axis of articulation 31 that when the panel 2 presents by relative to frame 1 a tilt angle A (Figure 2) within a specified range A0-A1 of angles inclination, defined between a minimum angle A0 (Figure 4) and a maximum angle A1 (Figure 5).

Selon l'invention, le méplat 310 de l'axe d'articulation 31 a, par rapport au cadre 1, une inclinaison J (Figure 2) supérieure à un angle droit, et l'angle minimal A0 est supérieur à un angle droit, la plage A0-A1 d'angles d'inclinaison autorisant l'engagement de l'oeil 32 dans l'axe d'articulation 31 ne comprenant donc que des angles d'inclinaison supérieurs à un angle droit.According to the invention, the flat 310 of the axis of articulation 31 has, with respect to frame 1, a tilt J (Figure 2) greater than a right angle, and the minimum angle A0 is greater than a right angle, the A0-A1 range of tilt angles allowing the engagement of the eye 32 in the axis of articulation 31 does not therefore understanding that tilt angles greater than A right angle.

Grâce à cet agencement, le panneau 2 ne peut être monté sur le cadre 1 que dans une position renversée, c'est-à-dire une position dans laquelle sa face externe 21 est davantage tournée vers le plan du cadre 1 que ne l'est sa face interne 22, le panneau 2 étant ainsi naturellement sollicité, par gravité, en dehors de l'ouverture O et n'ayant donc pas tendance à se fermer spontanément.Thanks to this arrangement, the panel 2 cannot be mounted on the frame 1 only in an inverted position, that is to say a position in which its external face 21 is more oriented towards the plane of frame 1 than does is its internal face 22, the panel 2 thus being naturally stressed, by gravity, outside opening O and therefore not tending to close spontaneously.

Comme le montre notamment la figure 2, le panneau 2 du dispositif illustré comprend une rampe 4 formant une surépaisseur sur la face externe 21 du panneau, adjacente à son bord d'articulation 20, et présentant une surface de raccordement 40 qui raccorde sans angle vif la surface externe 21 du panneau 2 à l'épaisseur 23 de ce dernier.As shown in particular in Figure 2, panel 2 of the illustrated device comprises a ramp 4 forming a additional thickness on the external face 21 of the panel, adjacent at its hinge edge 20, and having a surface 40 which connects the surface without sharp angles external 21 of the panel 2 to the thickness 23 of the latter.

Cette surface de raccordement 40, dont l'inclinaison évolue avantageusement de façon progressive, est en tout cas inclinée à la fois par rapport à la face externe 21 et par rapport à l'épaisseur 23 du panneau, pour permettre, au montage du panneau 2 sur le cadre 1, de guider ce panneau le long du bord d'articulation 10 du cadre jusqu'à ce que l'axe d'articulation 31 s'engage dans le guide de section réduite 320.This connection surface 40, of which the inclination advantageously changes so progressive, is in any case inclined at the same time by with respect to the external face 21 and with respect to the thickness 23 of the panel, to allow the mounting of panel 2 on frame 1, guide this panel along the edge hinge 10 of the frame until the axis 31 is engaged in the section guide reduced 320.

Sur le bord d'articulation 10 du cadre, la feuillure 12 du cadre présente une première came 5 qui est formée par une surélévation de la feuillure 12, et qui sert à bloquer le panneau 2.On the hinge edge 10 of the frame, the rebate 12 of the frame has a first cam 5 which is formed by an elevation of the rebate 12, and which is used to block the panel 2.

Plus précisément, comme le montre la figure 5, le panneau 2, dans sa position d'ouverture, est en butée en un point B1 par une partie relativement externe 231 de son épaisseur 23 sur la première came 5, en butée en un point B2 par sa face externe 21 sur le rebord 11 du cadre, et en butée en un point B3 par l'oeil d'articulation 32 ou le guide de section réduite 320 contre l'axe d'articulation 31.More specifically, as shown in Figure 5, the panel 2, in its open position, is in abutment at a point B1 by a relatively external part 231 of its thickness 23 on the first cam 5, in abutment in one point B2 by its external face 21 on the rim 11 of the frame, and in abutment at a point B3 by the eye hinge 32 or reduced section guide 320 against the hinge pin 31.

Par ailleurs, le panneau 2 présente, sur son bord d'articulation 20, un talon 230 qui fait saillie d'une partie médiane de son épaisseur 23, et qui est destiné à coopérer avec un flanc abrupt 51 de la came 5, dirigé vers la feuillure 12.In addition, panel 2 has, on its edge articulation 20, a heel 230 which projects from a middle part of its thickness 23, and which is intended for cooperate with an abrupt side 51 of the cam 5, directed to rebate 12.

Lorsque le panneau 2 est monté sur le cadre ou passe de sa position de fermeture à sa position d'ouverture, le talon 230 chemine sur la première came 5 et tombe de la première came 5, en s'appuyant en un point B4 le long du flanc abrupt 51, au moment où ce panneau atteint sa position d'ouverture. When panel 2 is mounted on the frame or goes from its closed position to its position opening, the heel 230 travels on the first cam 5 and falls from the first cam 5, resting on a point B4 along the steep side 51, when this panel reaches its open position.

Or, dans la mesure où, à cet instant, le centre de gravité de ce panneau s'abaisse et où le talon 230 bute sur le flanc 51 de la came 5, le panneau 2 est bloqué et ne peut être amené vers sa position de fermeture que sous réserve d'être soulevé, comme le montre le figure 6.Now, insofar as, at this instant, the center of gravity of this panel drops and where the heel 230 abuts on the side 51 of the cam 5, the panel 2 is blocked and can only be brought to its closed position under reserve to be lifted, as shown in figure 6.

De préférence, une fenêtre 110 (figures 1, 3, et 10) est creusée dans le rebord 11 du cadre 1, sur le bord d'articulation 10 de ce cadre, pour permettre le passage du talon 230 lors de la rotation du panneau 2 entre sa position de fermeture et sa position d'ouverture.Preferably, a window 110 (Figures 1, 3, and 10) is hollowed out in the edge 11 of the frame 1, on the edge hinge 10 of this frame, to allow passage of the heel 230 during the rotation of the panel 2 between its closed position and its open position.

Sur le bord d'articulation 10 du cadre, la feuillure 12 du cadre présente également une seconde came 6, qui est formée par une seconde surélévation de la feuillure, et qui sert à guider une partie relativement interne 232 (figure 2) de l'épaisseur 23 du panneau.On the hinge edge 10 of the frame, the rebate 12 of the frame also has a second cam 6, which is formed by a second elevation of the rebate, and which is used to guide a relatively internal 232 (figure 2) of the thickness 23 of the panel.

Plus précisément, cette partie 232 chemine sur la seconde came 6 lorsque le panneau 2 passe de sa position de fermeture à sa position d'ouverture ou inversement, le guidage assuré par cette came 6 permettant de déplacer progressivement l'oeil 32 et le guide de section réduite 320 par rapport à l'axe d'articulation 31.More specifically, this part 232 travels on the second cam 6 when the panel 2 passes from its position closing to its open position or vice versa, the guidance provided by this cam 6 making it possible to move gradually eye 32 and the reduced section guide 320 with respect to the hinge pin 31.

Enfin, la feuillure 12 du cadre présente, sur le bord d'articulation 10 du cadre, une troisième came 7, qui est formée par une troisième surélévation de la feuillure, et qui, au moins dans la position de fermeture du panneau 2, offre un appui à un pied 222 du panneau.Finally, the rebate 12 of the frame presents, on the hinge edge 10 of the frame, a third cam 7, which is formed by a third elevation of the rebate, and which, at least in the closed position of the panel 2, provides support for a leg 222 of the panel.

Comme le montrent le mieux les figures 1 et 10, l'axe d'articulation 31 n'a pas besoin d'être tenu à ses deux extrémités, mais peut au contraire présenter une extrémité libre 311 et une extrémité liée 312.As best shown in Figures 1 and 10, the hinge pin 31 does not need to be held at its two ends, but may on the contrary have a free end 311 and a linked end 312.

Dans ce cas, l'extrémité liée 312 de cet axe peut être portée par un voile 13 qui est perpendiculaire au rebord 11 et à la feuillure 12 du cadre et qui les relie l'un à l'autre. In this case, the linked end 312 of this axis can be carried by a veil 13 which is perpendicular to the edge 11 and the rebate 12 of the frame and which connects them to one another.

Enfin, pour simplifier la cinématique du panneau 2, le guide de section réduite 320 débouche de préférence dans une partie de l'oeil 32 qui est la plus éloignée de la face externe 21 du panneau 2.Finally, to simplify the kinematics of panel 2, the reduced section guide 320 preferably opens out in a part of eye 32 which is furthest from the external face 21 of the panel 2.

Le mode d'utilisation du dispositif illustré est le suivant.The mode of use of the illustrated device is next.

Pour monter le panneau 2 sur la cadre 1 (figure 2), la rampe 4 est placée sur la partie supérieure du rebord 11 du cadre 1.To mount the panel 2 on the frame 1 (figure 2), the ramp 4 is placed on the upper part of the ledge 11 of frame 1.

Bien que l'opérateur doive alors retenir le panneau, ce dernier glisse naturellement par son poids le long du rebord 11, dans une position qui conduit le guide 320 à s'engager sur l'axe 31 (figure 4).Although the operator must then retain the panel, the latter slides naturally by its weight along the edge 11, in a position which leads the guide 320 to engage on axis 31 (Figure 4).

Par la diminution progressive de la force de retenue exercée par l'opérateur, le panneau 2 se renverse légèrement et se bloque dans sa position d'ouverture (figure 5).By the gradual decrease in the strength of restraint exercised by the operator, panel 2 overturns slightly and locks in its open position (figure 5).

Pour placer le panneau 2 dans sa position de fermeture, l'opérateur doit d'abord le soulever (figure 6), puis l'accompagner (figures 7 et 8) jusqu'à ce que le panneau repose intégralement sur la cadre 1, le pied 222 étant alors en appui fixe sur la troisième came 7.To place panel 2 in its position closing, the operator must first lift it (figure 6), then accompany it (Figures 7 and 8) until the panel rests entirely on frame 1, leg 222 then being in fixed support on the third cam 7.
