Description

La présente invention concerne un dispositif de voirie comprenant un cadre de support et un élément de couronnement, tel qu'un tampon ou couvercle, monté articulé à basculement sur le cadre.The present invention relates to a road device comprising a support frame and a cap element, such as a buffer or cover, mounted pivotally hinged to the frame.

Elle s'applique en particulier à un regard de chaussée.It applies in particular to a look of roadway.

On connaît un tel dispositif selon lequel l'élément de couronnement est monté articulé à basculement sur le cadre le long d'une rive de l'élément de couronnement par au moins une charnière d'articulation entre une position de fermeture dans laquelle l'élément de couronnement s'inscrit dans un rebord périphérique du cadre pour s'appliquer au moins partiellement sur une face supérieure d'une feuillure d'assise du cadre et une position d'ouverture dans laquelle l'élément de couronnement est dressé pour accéder à l'ouverture du cadre. Un tel dispositif est connu par EP 0681066 A1 .Such a device is known according to which the crown element is pivotably mounted on the frame along a bank of the crown element by at least one articulation hinge between a closed position in which the element of crowning fits into a peripheral rim of the frame to at least partially apply to an upper face of a frame rebate and an open position in which the crown element is erected to access the opening of the frame. Such a device is known by EP 0681066 A1 .

L'élément de couronnement peut occuper soit une position d'ouverture dressée sensiblement perpendiculaire au plan du cadre et à laquelle l'élément de couronnement est bloqué pour l'empêcher de basculer accidentellement à sa position de fermeture du cadre, soit une position d'ouverture renversée sensiblement à 110 degrés relativement au plan du cadre.The cap element may occupy either an open position substantially perpendicular to the plane of the frame and to which the cap member is locked to prevent it from accidentally tilting to its closed position of the frame, ie a position of opening reversed substantially at 110 degrees relative to the plane of the frame.

Cependant, la charnière d'articulation et les moyens permettant de bloquer l'élément de couronnement à sa position dressée sensiblement verticale ou de le maintenir à sa position d'ouverture renversée sensiblement à 110 degrés sont d'une structure extrêmement complexe et coûteuse.However, the hinge hinge and the means for locking the crown member to its substantially upright raised position or to maintain it at its inverted opening position at substantially 110 degrees are of an extremely complex and expensive structure.

La présente invention a pour but de palier les inconvénients ci-dessus des dispositifs de voirie connus.The present invention aims to overcome the above disadvantages of known road devices.

A cet effet, selon l'invention, le dispositif de voirie comprenant un cadre de support et au moins un élément de couronnement, tel qu'un tampon ou couvercle, monté articulé à basculement sur le cadre le long d'une rive de l'élément de couronnement par au moins une charnière d'articulation entre une position de fermeture dans laquelle l'élément de couronnement s'inscrit dans un rebord périphérique du cadre pour s'appliquer au moins partiellement sur une face supérieure d'une feuillure d'assise du cadre et une position d'ouverture dans laquelle l'élément de couronnement est dressé, est caractérisé en ce que la charnière d'articulation comprend un axe cylindrique sensiblement parallèle au rebord correspondant du cadre et traversant des orifices de charnons d'articulation comprenant deux charnons solidaires de la face supérieure de la feuillure du cadre et dont les orifices sont des trous oblongs sensiblement perpendiculaires à la feuillure et deux charnons solidaires de la face interne de l'élément de couronnement, de manière que l'axe cylindrique puisse se déplacer librement dans les trous oblongs des charnons de la feuillure lors du basculement de l'élément de couronnement entre ses positions de fermeture et d'ouverture du cadre.For this purpose, according to the invention, the road device comprising a support frame and at least one cap element, such as a buffer or cover, pivotably mounted to tilt on the frame along a bank of the crown element by at least one articulation hinge between a closed position in which the crown element fits into a peripheral edge of the frame for at least partially applying to an upper face of a base rebate of the frame and an open position in which the cap element is erected, is characterized in that the hinge hinge comprises a cylindrical axis substantially parallel to the corresponding flange of the frame and passing through hinge knuckle orifices comprising two knuckles integral with the upper face of the rabbet of the frame and whose orifices are oblong holes substantially perpendicular to the rabbet and two integral knuckles of the inner face of the cap element, so that the cylindrical axis can move freely in the oblong holes of the notches of the rabbet when tilting the cap member between its closed and open positions of the frame.

Avantageusement, les orifices des charnons de l'élément de couronnement sont des trous oblongs sensiblement parallèles à la face interne de l'élément de couronnement.Advantageously, the orifices of the knuckles of the crown member are oblong holes substantially parallel to the internal face of the crown element.

De préférence, l'élément de couronnement comprend deux entailles parallèles traversant l'épaisseur de l'élément de couronnement en débouchant sur la rive de l'élément de couronnement perpendiculairement à celle-ci et chaque entaille est située dans le même plan qu'un charnon de la feuillure, a une largeur supérieure à l'épaisseur du charnon correspondant et une hauteur, partant de la rive de l'élément de couronnement, supérieure à la hauteur d'un charnon de feuillure.Preferably, the crowning element comprises two parallel cuts through the thickness of the crown element opening out on the edge of the crown element perpendicular to it and each notch is located in the same plane as herringbone of the rabbet, has a width greater than the thickness of the corresponding knuckle and a height, starting from the edge of the coronation element, greater than the height of a rabbet knuckle.

En position de fermeture de l'élément de couronnement, les deux charnons de la feuillure sont engagés respectivement dans les deux entailles.In the closed position of the crown element, the two knuckles of the rabbet are respectively engaged in the two notches.

L'élément de couronnement peut être bloqué à sa position dressée d'ouverture en appui sur la feuillure sensiblement perpendiculairement à cette dernière et entre les deux charnons de la feuillure et le rebord correspondant du cadre par les bords supérieurs des deux entailles en butée respectivement sur ces deux charnons et à cette position dressée de l'élément de couronnement, l'axe d'articulation est en appui par gravité sur les extrémités inférieures des deux trous oblongs des charnons de feuillure.The crown element can be locked at its upright opening position resting on the rabbet substantially perpendicularly to the latter and between the two notches of the rabbet and the corresponding rim of the frame by the upper edges of the two notches abutting respectively on these two knuckles and at this erect position of the crown element, the hinge axis is supported by gravity on the lower ends of the two oblong holes of the rabbet knuckles.

L'élément de couronnement peut être bloqué à sa position dressée d'ouverture sensiblement à 110° en arc-boutement sur le rebord du cadre par sa partie de rive en appui sous l'axe d'articulation en butée sur les extrémités supérieures des trous oblongs des deux charnons de feuillure.The crown element can be locked at its upright position of opening substantially at 110 ° in abutment on the rim of the frame by its edge portion bearing under the hinge axis abutting on the upper ends of the holes oblong of the two rabbet knuckles.

L'axe d'articulation est immobilisé en translation relativement aux charnons d'articulation.The axis of articulation is immobilized in translation relative to the hinge knuckles.

De préférence, l'axe d'articulation est immobilisé en translation d'une part par une agrafe en forme de pince enserrant une partie d'extrémité de cet axe à proximité de l'un des charnons de l'élément de couronnement adjacent à l'un des deux charnons de la feuillure entre lesquels est situé le charnon de l'élément de couronnement et d'autre part par la partie d'extrémité opposée de l'axe d'articulation engagée dans un orifice borgne de l'autre charnon de l'élément de couronnement adjacent à l'autre charnon de la feuillure à l'extérieur de ce dernier.Preferably, the hinge pin is immobilized in translation on the one hand by a clip-shaped clip enclosing an end portion of this axis near one of the knuckles of the crown member adjacent to the hinge pin. one of the two knuckles of the rabbet between which is located the knuckle of the crown member and secondly by the opposite end portion of the hinge pin engaged in a blind hole of the other knuckle of the crown element adjacent to the other hinge of the rabbet on the outside of the latter.

Chaque charnon de feuillure a une largeur au plus égale à la largeur de la feuillure.Each rabbet knuckle has a width at most equal to the width of the rabbet.

Les charnons de la feuillure et de l'élément de couronnement sont constitués chacun par un bloc sensiblement parallélépipédique de relativement faible épaisseur s'étendant perpendiculairement à la feuillure et à l'élément de couronnement.The knuckles of the rabbet and the crown element each consist of a substantially parallelepipedic block of relatively weak thickness extending perpendicular to the rabbet and the crown element.

Les charnons sont disposés les uns par rapport aux autres suivant un très faible jeu en direction parallèle à la paroi correspondante du rebord.The knuckles are arranged relative to each other in a very small clearance in a direction parallel to the corresponding wall of the rim.

Chaque élément de couronnement est constitué par un panneau rectangulaire.Each coronation element is constituted by a rectangular panel.

En position de fermeture du cadre 2, chaque panneau de couronnement 3 est appliqué sur la face supérieure 7a de la feuillure d'assise 7 par ses quatre coins comportant des plots de fonderie faisant saillie de la face interne du voile 8 et munis de rondelles en caoutchouc antibruit 10 venant en appui sur la face supérieure 7a de la feuillure d'assise 7.In the closed position of the frame 2, each cap panel 3 is applied to the upper face 7a of the base rebate 7 by its four corners including foundry studs protruding from the inner face of the web 8 and provided with washers. anti-noise rubber 10 bearing on the upper face 7a of the rebate 7.

A cette position de fermeture de chaque panneau 3, la face externe du voile 8 de ce panneau est en affleurement avec le bord supérieur du rebord périphérique 6.At this closing position of each panel 3, the outer face of the panel 8 of this panel is flush with the upper edge of the peripheral flange 6.

Chaque panneau de couronnement 3 peut occuper deux positions d'ouverture dressée, une position d'ouverture sensiblement perpendiculaire à la feuillure d'assise 7 à laquelle la plaque 3 est bloquée pour l'empêcher de basculer accidentellement à sa position de fermeture et une position d'ouverture renversée sensiblement à 110 degrés relativement au plan du bord d'ouverture du cadre 2 et à laquelle le panneau 3 est en arc-boutement sur la paroi correspondante du rebord périphérique 6 du cadre 2.Each cap panel 3 can occupy two erected opening positions, an open position substantially perpendicular to the seat rebate 7 to which the plate 3 is locked to prevent it from accidentally tilting to its closed position and a position aperture inverted substantially 110 degrees relative to the plane of the opening edge of the frame 2 and to which the panel 3 is buttressed on the corresponding wall of the peripheral flange 6 of the frame 2.

En position d'obturation du cadre 2, les panneaux de couronnement 3 sont juxtaposés les uns par rapport aux autres et dans un même plan.In the closed position of the frame 2, the crown panels 3 are juxtaposed relative to each other and in the same plane.

Le voile 8 de chaque panneau 3 présente une épaisseur relativement faible et est rigidifié par des nervures 9 solidaires de la face interne du voile 8.The web 8 of each panel 3 has a relatively small thickness and is stiffened by ribs 9 integral with the inner face of the web 8.

L'un des panneaux d'extrémité 3 est pourvu d'un verrou 11 à pêne 12 coopérant avec une gâche 13 du cadre 2 de manière qu'en position verrouillée de ce panneau au cadre 2, les autres panneaux 3 soient également immobilisés à leur position de fermeture dans le cadre 2, comme cela est connu en soi.One of the end panels 3 is provided with a bolt lock 12 cooperating with a striker 13 of the frame 2 so that in the locked position of the panel to the frame 2, the other panels 3 are also immobilized at their location. closing position in the frame 2, as is known per se.

Selon l'invention, chaque charnière d'articulation 5 comprend un axe cylindrique 14 sensiblement parallèle à la paroi correspondante du rebord périphérique 6 du cadre 2 et traversant des charnons d'articulation 15, 16 comprenant deux charnons 15 solidaires de la face supérieure 7a de la partie de feuillure correspondante 7 et deux charnons 16 solidaires de la face interne du voile 8 du panneau de couronnement 3.According to the invention, each articulation hinge 5 comprises a cylindrical axis 14 substantially parallel to the corresponding wall of the peripheral flange 6 of the frame 2 and passing through hinge knuckles 15, 16 comprising two knuckles 15 integral with the upper face 7a of the corresponding rebate portion 7 and two knuckles 16 secured to the inner face of the web 8 of the crown panel 3.

Les deux charnons 15 de la feuillure 7 comprennent respectivement deux trous oblongs 17 traversant suivant leur épaisseur les charnons 15 et sensiblement perpendiculaires à la feuillure 7.The two knuckles 15 of the rabbet 7 respectively comprise two oblong holes 17 traversing, according to their thickness, the knuckles 15 and substantially perpendicular to the rabbet 7.

Les deux charnons 16 de la plaque de recouvrement 3 comprennent deux orifices pouvant être constitués par des trous oblongs 18 sensiblement parallèles à la face interne du voile 8 du panneau 3. Le trou oblong 18 de l'un des charnons 16, situé entre les deux charnons 15 de la feuillure 7 de façon adjacente à l'un de ces deux charnons 15, traverse dans son épaisseur le charnon 16. L'autre charnon 16 disposé de manière adjacente à l'autre charnon 15 à l'extérieur de ce dernier a son trou oblong 18 qui est borgne.The two knuckles 16 of the cover plate 3 comprise two orifices which may consist of oblong holes 18 substantially parallel to the inner face of the web 8 of the panel 3. The oblong hole 18 of one of the knuckles 16, situated between the two 15 of the rabbet 7 adjacent to one of these two knuckles 15, through its thickness through the knuckle 16. The other knuckle 16 disposed adjacent to the other knuckle 15 outside the latter its oblong hole 18 which is one-eyed.

L'axe d'articulation 14 traverse les trous oblongs 17 des deux charnons 15 de la feuillure 7 et le trou oblong 18 du charnon 16 situé entre les deux charnons 15. En outre, la partie d'extrémité de l'axe d'articulation 14 est engagée dans le trou oblong borgne 18 de l'autre charnon 16 du panneau 3 pour immobiliser en translation dans un sens l'axe d'articulation 14 relativement aux charnons 15, 16.The hinge axis 14 passes through the oblong holes 17 of the two knuckles 15 of the rebate 7 and the oblong hole 18 of the knuckle 16 located between the two knuckles 15. In addition, the end portion of the hinge axis 14 is engaged in the blind oblong hole 18 of the other knuckle 16 of the panel 3 to immobilize in translation in one direction the hinge axis 14 relative to the knuckles 15, 16.

L'immobilisation en translation de l'axe d'articulation 14 dans le sens opposé s'effectue par une agrafe en forme de pince 19 mieux visible en figure 5 et enserrant la partie d'extrémité de l'axe 14 au niveau de la face du charnon 16 à trou borgne traversant 18 et opposée à la face de ce charnon adjacente à celle du charnon 15 de la feuillure 7.The immobilization in translation of the hinge pin 14 in the opposite direction is effected by a clip-shaped clip 19 which is better visible in figure 5 and enclosing the end portion of the axis 14 at the face of the knuckle 16 with through blind hole 18 and opposite the face of this knuckle adjacent to that of the knuckle 15 of the rabbet 7.

Les charnons 15, 16 sont disposés relativement les uns par rapport aux autres de manière à ne laisser subsister qu'un très faible jeu suivant la direction longitudinale de la charnière d'articulation 5 parallèle à la paroi correspondante du rebord périphérique 6 du cadre 2.The knuckles 15, 16 are arranged relative to each other so as to leave only a very small clearance in the longitudinal direction of the articulation hinge 5 parallel to the corresponding wall of the peripheral flange 6 of the frame 2.

Ainsi, lors du basculement du panneau de couronnement 3 entre ses deux positions d'obturation et d'ouverture du cadre 2, l'axe d'articulation 14 peut se déplacer librement dans les trous oblongs 17 des deux charnons 15 de la feuillure 7. Autrement dit, cet axe est monté flottant dans les charnons 15 de la feuillure 7.Thus, during the tilting of the crown panel 3 between its two positions of closing and opening of the frame 2, the hinge axis 14 can move freely in the oblong holes 17 of the two knuckles 15 of the rabbet 7. In other words, this axis is mounted floating in the knuckles 15 of the rabbet 7.

Chacun des charnons 15, 16 est constitué par un bloc sensiblement parallélépipédique de relativement faible épaisseur de telle sorte que les charnons 15 s'étendent perpendiculairement de la face supérieure de la feuillure 7 et les deux charnons 16 s'étendent perpendiculairement de la face interne du voile 8 du panneau de couronnement 3.Each of the knuckles 15, 16 is constituted by a substantially parallelepipedal block of relatively small thickness so that the knuckles 15 extend perpendicularly from the upper face of the rabbet 7 and the two knuckles 16 extend perpendicularly from the inner face of the sail 8 of the crown panel 3.

En outre, chaque charnon de feuillure 15 a une largeur au plus égale à la largeur de la feuillure 7 de manière à ne pas déborder de cette feuillure.In addition, each rabbet knuckle 15 has a width at most equal to the width of the rabbet 7 so as not to overflow this rabbet.

Chaque panneau de couronnement 3 comprend deux entailles parallèles 20 traversant l'épaisseur du voile 8 du panneau 3 en débouchant sur la rive 4 de ce panneau perpendiculairement à la rive.Each cap panel 3 comprises two parallel cuts 20 crossing the thickness of the veil 8 panel 3 opening on the bank 4 of this panel perpendicular to the shore.

Chaque entaille, de forme générale rectangulaire, est située dans le même plan qu'un charnon correspondant 15 de la feuillure 7 et a une largeur supérieure à l'épaisseur du charnon correspondant 15. En outre, chaque entaille 20 a une hauteur, partant de la rive 4 du panneau de couronnement 3, supérieure à la hauteur du charnon correspond 15 de la feuillure 7.Each notch, of generally rectangular shape, is located in the same plane as a corresponding knuckle 15 of the rabbet 7 and has a width greater than the thickness of the corresponding knuckle 15. In addition, each notch 20 has a height, starting from the edge 4 of the crown panel 3, greater than the height of the knuckle 15 corresponds to the rabbet 7.

Les figures 1 et 2 montrent qu'en position de fermeture de chaque panneau de couronnement 3 dans le cadre 2, les deux charnons 15 de la feuillure 7 sont engagés respectivement dans les deux entailles 20 du panneau sans faire saillie à l'extérieur de ces dernières.The figures 1 and 2 show that in the closed position of each cap panel 3 in the frame 2, the two knuckles 15 of the rabbet 7 are respectively engaged in the two notches 20 of the panel without protruding outside of the latter.

La figure 3 montre que le panneau de couronnement 13 est bloqué à sa position dressée perpendiculaire à la feuillure 7 sur laquelle le panneau 3 prend appui par sa rive 4. A cette position, la partie inférieure du panneau de couronnement 3 est bloquée entre les deux charnons 15 de la feuillure 7 et la paroi verticale correspondante du rebord périphérique 6 du cadre 2 par les bords supérieurs des deux entailles 20 en butée respectivement sur les deux charnons 15 du fait que la hauteur des deux entailles 20 à partir de la feuillure 7 est inférieure à la hauteur des charnons correspondants 15. De la sorte, le panneau de couronnement 3 ne peut basculer accidentellement de sa position verticale à sa position de fermeture du cadre 2. Pour permettre ce basculement, il est alors nécessaire de soulever le panneau de couronnement 13 pour désengager les entailles 20 des charnons correspondants 15 puis de faire basculer le panneau 3 à sa position de fermeture du cadre 2.The figure 3 shows that the cap panel 13 is locked at its upright position perpendicular to the rabbet 7 on which the panel 3 is supported by its side 4. At this position, the lower part of the cap panel 3 is locked between the two knuckles 15 of the rabbet 7 and the corresponding vertical wall of the peripheral flange 6 of the frame 2 by the upper edges of the two notches 20 abutting respectively on the two knuckles 15 because the height of the two notches 20 from the rabbet 7 is less than the Corresponding knuckle height 15. In this way, the crown panel 3 can not accidentally tilt from its vertical position to its closed position of the frame 2. To allow this tilting, it is then necessary to lift the cap panel 13 to disengage the notches 20 corresponding knuckles 15 and then tilt the panel 3 to its closed position of the frame 2.

En outre, à la position dressée verticale du panneau de couronnement 3 à laquelle les trous oblongs 17 des charnons 15 et 18 des charnons 16 sont alignés les uns par rapport aux autres verticalement par rapport à la feuillure 7, l'axe d'articulation 14 est en appui par gravité sur les extrémités inférieures d'au moins les trous oblongs 17 des charnons 15 et, le cas échéant, des trous oblongs 18 des charnons 16.In addition, at the upright position of the crown panel 3 to which the oblong holes 17 of the knuckles 15 and 18 of the knuckles 16 are aligned with each other vertically with respect to the rebate 7, the hinge pin 14 is supported by gravity on the lower ends of at least the oblong holes 17 of the knuckles 15 and, where appropriate, oblong holes 18 of the knuckles 16.

La figure 4 représente le panneau de couronnement 3 qui est bloqué à sa position renversée sensiblement à 110 degrés en arc-boutement sur la paroi correspondante du rebord périphérique 6 du cadre 2 par sa partie de rive 4 en appui sous l'axe d'articulation 14 en butée sur les extrémités supérieures des trous oblongs 17 des deux charnons 15 de la feuillure 7. Ainsi, ce sont l'axe d'articulation 14 et les charnons 15 de la feuillure 7 de la charnière d'articulation qui retiennent la plaque de couronnement 13 à sa position renversée sensiblement à 110 degrés en dehors du cadre 2. La figure 4 montre qu'à cette position les deux charnons 15 sont engagés en partie au travers de leurs entrailles respectives. Pour amener le panneau de couronnement 3 à sa position de fermeture du cadre 2 à partir de la position renversée de la figure 4, il suffit de soulever le panneau 3 pour le disposer à une position sensiblement perpendiculaire à la feuillure 7, puis de le faire basculer vers sa position de fermeture du cadre 2. Il est à noter que la plaque de couronnement 3 peut être amenée à sa position sensiblement verticale de la figure 3 à partir de sa position renversée de la figure 4 pour empêcher le retour du panneau 3 à sa position de fermeture du cadre 2.The figure 4 represents the crown panel 3 which is locked in its reverse position substantially at 110 degrees in abutment on the corresponding wall of the peripheral flange 6 of the frame 2 by its edge portion 4 bearing under the hinge axis 14 in abutment on the upper ends of the oblong holes 17 of the two knuckles 15 of the rabbet 7. Thus, it is the hinge axis 14 and the knuckles 15 of the rebate 7 of the hinge hinge which retain the crown plate 13 to its reverse position substantially to 110 degrees outside frame 2. The figure 4 shows that in this position the two knuckles 15 are engaged in part through their respective entrails. To bring the crown panel 3 to its closed position of the frame 2 from the inverted position of the figure 4 it is sufficient to raise the panel 3 to arrange it at a position substantially perpendicular to the rabbet 7, then to tilt it towards its closed position of the frame 2. It should be noted that the cap plate 3 can be brought to its original position. substantially vertical position of the figure 3 from his overturned position of the figure 4 to prevent the return of the panel 3 to its closed position of the frame 2.

Le dispositif de l'invention permet, par une conception extrêmement simple d'une charnière d'articulation d'un élément de couronnement à un cadre de support de regard de chaussée, de basculer l'élément de couronnement de sa position de fermeture du cadre à une position d'ouverture de ce cadre, soit sensiblement verticale à laquelle l'élément de couronnement est bloqué pour l'empêcher de retourner à sa position de fermeture, soit renversée sensiblement à 110 degrés en arc-boutement sur la paroi correspondante du rebord périphérique du cadre.The device of the invention makes it possible, by an extremely simple design of a hinge of articulation of a crown element to a support frame of manhole, to tilt the element of crowning of its closed position of the frame at an open position of this frame, is substantially vertical to which the cap element is blocked to prevent it from returning to its closed position, is reversed substantially to 110 degrees in buttresses on the corresponding wall of the peripheral edge of the frame.
