Lorsque l'élément de recouvrement 3 est rabattu vers sa position d'obturation 6 de l'ouverture 0 du cadre 2, l'extrémité de la béquille 4 coulisse le long des lumières 6a jusqu'à venir à proximité des extrémités opposées des lumières 6a en position rabattue de l'élément de recouvrement de manière que la béquille occupe une position repliée dans le cadre 2 le long du côté 2b. A crutch 4 has one end hingedly mounted to one of the sides 2b of the frame 2 perpendicular to the side 2a through a yoke 5 pivot axis perpendicular to the side 2b. This crutch makes it possible to retain the covering element 3 in its upright position from the opening 0 shown in FIG. 1. For this purpose, the end of the stand 4 opposite to the hinge clevis 5 abuts in two ends of two parallel lights 6a made respectively in two parallel plates 6 integral with the corresponding inner side wall 3b of the covering element 3. When the covering element 3 is folded towards its closed position 6 of the opening 0 of the frame 2, the end of the stand 4 slides along the lights 6a to come close to the opposite ends of the lights 6a in the folded position of the cover element so that the stand is in a folded position in the frame 2 along the side 2b .
Le dispositif de voirie 1 comprend en outre une grille unique de sécurité antichute 7 montée articulée par l'un de ses bords 7a relativement au côté 2c du cadre 2 opposé et parallèle au côté 2b de ce cadre.  The road device 1 further comprises a single fall arrest safety gate 7 mounted articulated by one of its edges 7a relative to the side 2c of the frame 2 opposite and parallel to the side 2b of this frame.
La grille 7 comporte plusieurs barreaux parallèles cylindriques 7b fixés à leurs extrémités respectivement par deux barres planes parallèles 7a, 7c constituant les deux côtés de la grille 7.  The grid 7 comprises a plurality of cylindrical parallel bars 7b fixed at their ends respectively by two parallel flat bars 7a, 7c constituting the two sides of the grid 7.
La grille 7 est montée articulée relativement au côté 2c du cadre 2 suivant un axe Yl, Y2 parallèle au côté 2c et, par conséquent, perpendiculaire à l'axe de pivotement XI, X2 de l'élément de recouvrement 3.  The grid 7 is articulated relative to the side 2c of the frame 2 along an axis Y1, Y2 parallel to the side 2c and consequently perpendicular to the pivot axis XI, X2 of the covering element 3.
Ainsi, lorsque l'élément de recouvrement 3 occupe sa position dressée de dégagement de l'ouverture 0 du cadre 2, la grille 7 peut pivoter entre une position debout de dégagement de cette ouverture représentée en figure 1 à laquelle elle est sensiblement perpendiculaire au plan du cadre 2 et une position rabattue de fermeture de cette ouverture représentée en figure 2, dite de sécurité antichute.  Thus, when the covering element 3 occupies its erected position of the opening 0 of the frame 2, the grid 7 can pivot between a standing position of the opening shown in FIG. 1 to which it is substantially perpendicular to the plane frame 2 and a folded position closing this opening shown in Figure 2, called fall arrest.
Selon l'invention, la grille 7 peut également être montée articulée par son côté 7a au côté 2b du cadre 2 opposé au côté 2c suivant un axe Y3, Y4 parallèle au côté 2b et, par conséquent, perpendiculaire à l'axe de pivotement XI, X2 de l'élément de recouvrement 3.  According to the invention, the grid 7 can also be mounted articulated by its side 7a to the side 2b of the frame 2 opposite the side 2c along an axis Y3, Y4 parallel to the side 2b and, therefore, perpendicular to the pivot axis XI , X2 of the covering element 3.
Les moyens d'articulation du côté 7a de la grille 7 à l'un ou l'autre des deux côtés 2b, 2c du cadre 2 comprennent deux pattes parallèles 8 solidaires du côté 7a sensiblement perpendiculairement à ce dernier en étant disposées à l'extérieur de la grille. De préférence, les deux pattes 8 sont fixées respectivement au voisinage des deux extrémités du côté 7a de cette grille. Les pattes 8 peuvent être fixées au côté 7a par soudage. Chaque patte d'articulation 8 comporte une lumière 9 s'étendant longitudinalement à la patte 8. Plus précisément, chaque patte 8 se présente sous la forme d'une plaque rigide coudée sensiblement à angle droit dont l'une des branches 8a est solidaire d'une extrémité correspondante du côté 7a de la grille 7 et l'autre branche 8b comporte la lumière 9 s'étendant longitudinalement à la branche 8b. The means of articulation of the side 7a of the grid 7 to one or the other of the two sides 2b, 2c of the frame 2 comprise two parallel legs 8 secured to the side 7a substantially perpendicular to the latter being disposed outside the gate. Preferably, the two lugs 8 are respectively fixed in the vicinity of the two ends of the side 7a of this grid. The tabs 8 may be attached to the side 7a by welding. Each hinge lug 8 has a slot 9 extending longitudinally to the lug 8. Specifically, each lug 8 is in the form of a rigid plate bent substantially at right angles, one of the branches 8a is integral with a corresponding end of the side 7a of the gate 7 and the other leg 8b comprises the slot 9 extending longitudinally to the branch 8b.
Les moyens d'articulation de la grille 7 au cadre 2 comprennent également, associées à chaque côté 2b, 2c, deux chapes 10 solidaires d'une paroi interne 11 du cadre 2 s'étendant dans l'ouverture 0 perpendiculairement au côté correspondant 2b, 2c du cadre 2. Chaque paire de chapes 10 est fixée, par exemple par soudage, perpendiculairement à la paroi interne correspondante 11 au-dessus de celle-ci.  The articulation means of the grid 7 to the frame 2 also comprise, associated with each side 2b, 2c, two clevises 10 integral with an inner wall 11 of the frame 2 extending in the opening 0 perpendicular to the corresponding side 2b, 2c of the frame 2. Each pair of clevises 10 is fixed, for example by welding, perpendicularly to the corresponding inner wall 11 above it.
Les deux pattes 8 de la grille 7 sont montées articulées de façon amovible respectivement dans les deux chapes 10 de la paroi 11 associée au côté 2c du cadre 2 par l'intermédiaire de boulons de fixation 12 s'étendant le long de l'axe de pivotement Yl, Y2 de la grille 7 relativement au côté 2c. Chaque boulon de fixation 12 a sa tige filetée 12a traversant les deux branches parallèles 10a de la chape correspondante 10 perpendiculairement à celles-ci. Le diamètre de la tige filetée 12a du boulon 12 est légèrement inférieure au diamètre de deux perçages coaxiaux 10b réalisé au travers respectivement des deux branches 10a de la chape correspondante 10. En outre, la tige filetée 12a de chaque boulon 12 traverse également la lumière en forme de trou oblong 9 de la branche 8b de la patte 8 associée à la chape 10. Chaque chape 10 comprend également une paroi dorsale 10c solidaire, par exemple par soudage, des deux bords verticaux situés d'une même côté des branches 10a de la chape 10 en regard du côté vertical 2c du cadre 2, la paroi dorsale 10c étant ainsi espacée de ce côté 2c . The two lugs 8 of the grid 7 are mounted detachably articulated respectively in the two clevises 10 of the wall 11 associated with the side 2c of the frame 2 by means of fixing bolts 12 extending along the axis of pivot Y1, Y2 of the grid 7 relative to the side 2c. Each fixing bolt 12 has its threaded rod 12a passing through the two parallel branches 10a of the corresponding yoke 10 perpendicular thereto. The diameter of the threaded rod 12a of the bolt 12 is slightly less than the diameter of two coaxial bores 10b formed through respectively the two branches 10a of the corresponding yoke 10. In addition, the threaded rod 12a of each bolt 12 also passes through the lumen. oblong hole form 9 of the branch 8b of the tab 8 associated with the clevis 10. Each clevis 10 also comprises a dorsal wall 10c secured, for example by welding, the two vertical edges located on the same side of the legs 10a of the yoke 10 facing the vertical side 2c of the frame 2, the dorsal wall 10c thus being spaced from this side 2c.
La grille 7 comporte à son côté 7c opposé au côté d'articulation 7a deux pattes en équerre 13 fixées, par exemple par soudage par l'une de leurs branches au côté 7c à l'extérieur de la grille 7 de façon que l'autre branche de chaque patte 13 s'étende dans un plan parallèle au plan de la grille 7 au-dessus du côté 7c.  The gate 7 has at its side 7c opposite the hinge side 7a two brackets 13 fixed, for example by welding by one of their branches to the side 7c outside the gate 7 so that the other branch of each lug 13 extends in a plane parallel to the plane of the grid 7 above the side 7c.
Chaque patte en équerre 13 comporte solidaire de la face supérieure de la branche libre de cette patte une poignée externe de préhension 14 et le côté 7c de la grille 7 est également pourvu d'une poignée de préhension externe 15 située sensiblement au milieu de ce côté.  Each bracket 13 comprises integral with the upper face of the free leg of this tab an external grip 14 and the side 7c of the grid 7 is also provided with an external grip 15 located substantially in the middle of this side .
En position rabattue de la grille 7 représentée en figure 2, les deux pattes 13 viennent en appui sur la paroi interne 11 associée au côté 2b du cadre 2.  In the folded position of the grid 7 shown in FIG. 2, the two lugs 13 bear against the inner wall 11 associated with the side 2b of the frame 2.
En outre, la position de l'axe de pivotement Yl, Y2 de la grille 7 relativement au côté 2c du cadre 2 et les positions relatives des pattes d'appui 13 relativement au côté 7c de la grille 7 sont telles qu'en position rabattue de cette grille, cette dernière est logée dans les côtés 2a à 2d du cadre 2 sensiblement à mi- hauteur de ces côtés.  In addition, the position of the pivot axis Y1, Y2 of the grid 7 relative to the side 2c of the frame 2 and the relative positions of the support lugs 13 relative to the side 7c of the grid 7 are such that in the folded position of this grid, the latter is housed in the sides 2a to 2d of the frame 2 substantially halfway up these sides.
Lorsqu'un opérateur souhaite effectuer le pivotement de la grille 7 aux chapes 10 suivant l'axe de pivotement Y3, Y4 parallèle au côté 2b du cadre 2, il retire les boulons 12 des chapes 10 de la paroi interne 11 associée au côté 2c de ce cadre pour lui permettre de retirer la grille 7 de ces chapes.  When an operator wishes to pivot the gate 7 to the yokes 10 along the pivot axis Y3, Y4 parallel to the side 2b of the frame 2, he removes the bolts 12 from the yokes 10 of the inner wall 11 associated with the side 2c of this frame to allow it to remove the grid 7 of these screeds.
Ensuite, par pivotement de la grille sur elle même de 180° suivant l'axe du barreau central 7b de la grille 7, l'opérateur engage les deux pattes d'articulation 8 de cette grille respectivement dans les deux autres chapes 10 situées à proximité du côté 2b du cadre 2 et fixe les pattes 8 aux chapes 10 par les boulons de fixation 12 qui s'étendent ainsi le long de l'axe de pivotement Y3, Y4 de la grille 7. De la sorte, une fois la grille 7 fixée aux deux autres chapes 10, elle peut pivoter autour de l'axe Y3, Y4 entre une position debout sensiblement perpendiculaire au plan du cadre 2 et une position rabattue de fermeture de 1 ' ouverture 0 du cadre 2 à laquelle les pattes 13 sont en appui sur la paroi interne 11 associée au côté 2c du cadre 2. Then, by pivoting the grid on itself 180 ° along the axis of the central bar 7b of the grid 7, the operator engages the two hinge lugs 8 of this grid respectively in the other two yokes 10 located nearby side 2b of the frame 2 and fixes the tabs 8 to the yokes 10 by the fastening bolts 12 which thus extend along the pivot axis Y3, Y4 of the grid 7. In this way, once the grid 7 is attached to the other two yokes 10, it can pivot about the axis Y3, Y4 between a standing position substantially perpendicular to the plane of the frame 2 and a closed position of closure of the opening 0 of the frame 2 to which the lugs 13 bear on the inner wall 11 associated with the side 2c of the frame 2.
Il est à noter que le basculement de la grille 7 entre ses positions rabattue et debout est facilité par les lumières 9 des pattes 8 au travers desquelles s'engagent les boulons de fixation 12. En outre, les moyens d'articulation de la grille 7 relativement aux côtés correspondants 2b, 2c du cadre 2 constitués par les paires de chape 10, les boulons 12 et les lumières 9 sont conçus pour autobloquer la grille à sa position debout. EN effet, lorsque la grille 7 bascule de sa position rabattue horizontale à sa position debout sensiblement verticale représentée en figure 3, l'opérateur relâche la grille 7 qui descend par gravité de sa position de la figure 3 à sa position représentée en figure 4 par glissement des lumières 9 des deux pattes 8 relativement aux tiges filetées 12a des deux boulons 12. A la position représentée en figure 4, l'extrémité supérieure de la lumière 9 de chaque patte 8 est en appui sur la tige filetée correspondante 12a du boulon 12 et l'extrémité inférieure de la branche 8b de la patte 8 est en appui par son bord arrière sur la face interne de la paroi dorsale 10c de la chape 10 de sorte que la branche 8b de chaque patte 8 est autobloquée dans la chape 10 pour empêcher la grille 7 de basculer vers sa position rabattue de fermeture de l'ouverture 0 du cadre 2. Pour amener la grille 7 de sa position debout autobloquée relativement au cadre 2 à sa position rabattue dans le cadre, il suffit tout simplement de soulever la grille 7 pour libérer chaque branche 8b des deux pattes 8 de la grille de leur position de blocage dans la chape 10 jusqu'à ce que l'extrémité inférieure de la lumière 9 vienne en appui sur la tige filetée correspondante 12a du boulon 12, autorisant alors le libre basculement de la grille 7 vers sa position rabattue. It should be noted that the tilting of the grid 7 between its folded and standing positions is facilitated by the lights 9 of the lugs 8 through which the fixing bolts 12 engage. In addition, the hinge means of the grid 7 relative to the corresponding sides 2b, 2c of the frame 2 constituted by the pairs of clevis 10, the bolts 12 and the lights 9 are designed to self-lock the grid to its standing position. Indeed, when the gate 7 switches from its horizontal folded position to its substantially vertical standing position shown in Figure 3, the operator releases the gate 7 which descends by gravity from its position in Figure 3 to its position shown in Figure 4 by sliding of the slots 9 of the two tabs 8 relative to the threaded rods 12a of the two bolts 12. In the position shown in FIG. 4, the upper end of the slot 9 of each tab 8 bears against the corresponding threaded rod 12a of the bolt 12 and the lower end of the leg 8b of the tab 8 is supported by its rear edge on the inner face of the back wall 10c of the yoke 10 so that the leg 8b of each lug 8 is self-locking in the yoke 10 to prevent the gate 7 from swinging to its folded position closing the opening 0 of the frame 2. To bring the gate 7 from its self-locking standing position relative to the frame 2 to its folded position da in the frame, simply lift the grid 7 to release each branch 8b of the two legs 8 of the gate of their blocking position in the yoke 10 until the lower end of the light 9 bears on the corresponding threaded rod 12a of the bolt 12, then allowing the free swing of the gate 7 to its folded position.
Selon une variante non représentée, à la position debout de la grille 7, les pattes d'articulation 8 peuvent pivoter librement sur les boulons 12 et être amenées en appui sur la face interne du côté correspondant 2b ou 2c du cadre 2 pour maintenir la grille à cette position légèrement inclinée au-delà de sa position perpendiculaire au plan du cadre 2.  According to a variant not shown, in the standing position of the grid 7, the hinge lugs 8 can pivot freely on the bolts 12 and be brought in support on the inner face of the corresponding side 2b or 2c of the frame 2 to maintain the grid at this position slightly inclined beyond its position perpendicular to the plane of the frame 2.
Le fait que la grille puisse être montée articulée de manière réversible aux côtés 2b, 2c du cadre 2 permet de la positionner lorsqu'elle occupe sa position debout sans occasionner de gêne lors d'opération particulière à effectuer dans le réseau souterrain au travers de l'ouverture 0, par exemple en introduisant des câbles au travers de cette ouverture.  The fact that the grid can be mounted articulated reversibly to the sides 2b, 2c of the frame 2 allows to position it when it is in its upright position without causing any inconvenience during a particular operation to be carried out in the underground network through the opening 0, for example by introducing cables through this opening.
Lorsqu'un opérateur souhaite fermer le dispositif de voirie de la position représentée en figure 1 à la position représentée en figure 2, il fait pivoter la grille 7 de sa position debout autour de l'axe Yl, Y2 vers sa position rabattue de fermeture.  When an operator wishes to close the road device of the position shown in Figure 1 in the position shown in Figure 2, it rotates the grid 7 from its standing position about the axis Y1, Y2 to its folded closed position.
La figure 2 représente la grille à sa position rabattue de sécurité dans le cadre 2 empêchant toute personne de chuter accidentellement au travers de 1 ' ouverture 0 du cadre 2.  FIG. 2 shows the grid in its folded safety position in the frame 2 preventing anyone from accidentally falling through the opening 0 of the frame 2.
Lorsque l'opérateur, une fois les travaux de réfection ou d'aménagement effectués, souhaite fermer le dispositif de voirie, il lui suffit tout simplement, après avoir rabattu la grille 7 à sa position de fermeture à la figure 2, de rabattre ensuite l'élément de recouvrement 3 dans le cadre 2 de façon que cet élément, lorsqu'il occupe sa position d'obturation de l'ouverture 0 du cadre 2, recouvre complètement la grille 7 sans que cette dernière occasionne de gêne pour la fermeture de l'élément de recouvrement 3. A sa position de fermeture, l'élément de recouvrement 3 repose à l'opposé de l'axe de pivotement XI, X2 sur deux blocs d'appui 16 solidaires de la face interne du côté 2d du cadre 2. A cette position de fermeture, l'élément de recouvrement 3 peut être verrouillé au côté 2d du cadre 2 par des moyens de verrouillage habituels 17, 18 qui n'ont pas à être décrits car ne faisant pas partie de l'invention. When the operator, once the repair or development work is done, wants to close the road device, it suffices for him simply, after folding the grid 7 to its closed position in Figure 2, then fold down the l covering element 3 in the frame 2 so that this element, when it occupies its closed position of the opening 0 of the frame 2, completely covers the grid 7 without the latter causing any inconvenience to the closure of the cover member 3. In its closed position, the cover member 3 rests opposite the pivot axis XI, X2 on two support blocks 16 integral with the inner face of the side 2d of the frame 2. At this closed position, the cover member 3 can be locked to the side 2d of the frame 2 by conventional locking means 17, 18 which do not have to be described as not part of the invention.
La grille 7 peut être réalisée en acier, en acier inoxydable, en matériau composite et peut avoir une structure non seulement en barreaux comme décrit précédemment, mais également en treillis, en grillage ou en caillebotis. La grille 7 peut résister à une gamme d'efforts pouvant être compris entre environ 1500 et 3000 Newtons .  The grid 7 may be made of steel, stainless steel, composite material and may have a structure not only in bars as described above, but also in lattice, mesh or grating. The grid 7 can withstand a range of efforts that can be between about 1500 and 3000 Newtons.
Les avantages de l'invention sont les suivants : The advantages of the invention are as follows:
- le fait que la grille puisse être autobloquée à environ 90° relativement au cadre de support l'empêche de basculer à sa position horizontale dans le cadre même en cas de vent ou de mauvaises manipulations, assurant ainsi à un opérateur l'entrée dans la chambre ou de remontée de celle-ci en tout sécurité ; - The fact that the grid can be locked at about 90 ° relative to the support frame prevents it from tilting to its horizontal position in the frame even in case of wind or mishandling, thus ensuring an operator entry into the room or lift of it in complete safety;
- le fait que la grille soit réversible permet de la positionner à l'un ou l'autre des deux côtés opposés du cadre de support, de manière à ne pas occasionner de gêne lorsqu'elle occupe sa position debout, notamment lors d'une intervention dans le réseau souterrain ;  the fact that the grid is reversible makes it possible to position it on one or the other of the two opposite sides of the support frame, so as not to cause any discomfort when it occupies its upright position, in particular during a intervention in the underground network;
en position debout de la grille de sécurité, l'ouverture du cadre est totalement dégagée sans risque de blessure d'un opérateur rentrant dans le réseau souterrain ou remontant de ce réseau au travers d' ouverture du fait que les moyens d' articulation de la grille sont fixé sur la paroi horizontale, perpendiculaire au côté vertical correspondant du cadre en dehors de cette ouverture ; et  in the standing position of the safety grille, the opening of the frame is completely clear without the risk of injury to an operator returning to the underground network or coming up from this network through an opening because the means of articulation of the grid are fixed on the horizontal wall, perpendicular to the corresponding vertical side of the frame outside this opening; and
le démontage des boulons d' articulation de la grille au cadre est facilité du fait que les boulons d'articulation sont situés au-dessus de la paroi interne horizontale délimitant l'ouverture du cadre de sorte que l'opérateur n'a pas besoin de se pencher énormément pour accéder au boulon d'articulation. disassembly of the hinge bolts from the grid to the frame is facilitated by the fact that the bolts hinge are located above the horizontal inner wall defining the opening of the frame so that the operator does not need to bend heavily to access the hinge bolt.
