Sur la Figure 1 est représenté partiellement un regard de chaussée selon l'invention, désigné par la référence générale 2.On the Figure 1 is partially shown a manhole according to the invention, designated by the general reference 2.

Le regard de chaussée 2 comprend un cadre 4 et un élément de recouvrement du cadre 4, en l'occurrence un tampon 6.The manhole 2 comprises a frame 4 and a covering element of the frame 4, in this case a buffer 6.

Le cadre 4 délimite une ouverture 8 et est muni d'un rebord intérieur 10 sur lequel est disposé un joint d'insonorisation (non représenté). Le cadre 4 comporte une surface supérieure 12 s'étendant selon un plan supérieur PS-PS, et une surface inférieure 14 s'étendant selon un plan inférieur PI-PI. A l'état installé, la surface supérieure 12 du cadre affleure sensiblement une surface de sol 18. Le cadre 4 délimite un axe central de cadre X-X s'étendant sensiblement perpendiculairement au plan PS-PS.The frame 4 defines an opening 8 and is provided with an inner rim 10 on which is disposed a soundproofing joint (not shown). The frame 4 has an upper surface 12 extending in an upper plane PS-PS, and a lower surface 14 extending in a lower plane PI-PI. In the installed state, the surface upper frame 12 is substantially flush with a ground surface 18. The frame 4 defines a central frame axis XX extending substantially perpendicular to the PS-PS plane.

Le regard de chaussée 2 est disposé sur un socle 15 en matériau de scellement 16 tel que du béton. Le cadre 4 est partiellement enrobé par le matériau de scellement 16.The manhole 2 is disposed on a base 15 of sealing material 16 such as concrete. The frame 4 is partially coated with the sealing material 16.

Le cadre 4 est délimité par une paroi de cadre extérieure 20. Cette paroi de cadre extérieure 20 a une forme sensiblement tronconique autour de l'axe central de cadre X-X.The frame 4 is delimited by an outer frame wall 20. This outer frame wall 20 has a substantially frustoconical shape around the central frame axis X-X.

Le tampon 6 comporte un voile 22 fermé adapté pour recouvrir l'ouverture 8.The buffer 6 comprises a closed web 22 adapted to cover the opening 8.

Le regard de chaussée 2 est muni d'une charnière 24 formée par un charnon de cadre 26 et un charnon d'élément de recouvrement 28. Le charnon de cadre 26 est solidaire du cadre 4 et le charnon d'élément de recouvrement 28 est solidaire du tampon 6.The manhole 2 is provided with a hinge 24 formed by a frame knuckle 26 and a covering element knuckle 28. The frame knuckle 26 is integral with the frame 4 and the covering element knuckle 28 is secured to buffer 6.

Le charnon de cadre 26 et le charnon d'élément de recouvrement 28 sont adaptés pour permettre un basculement du tampon 6 par rapport au cadre 4 autour d'un axe d'articulation Y-Y et ceci entre une position fermée, telle que représentée sur la Figure 1, et une position ouverte dans laquelle le tampon 6 libère substantiellement l'ouverture 8 du cadre 4.The frame knuckle 26 and the covering member knuckle 28 are adapted to allow the pad 6 to tilt relative to the frame 4 about an axis of articulation YY and this between a closed position, as shown in FIG. Figure 1 , and an open position in which the buffer 6 substantially releases the opening 8 of the frame 4.

La position ouverte correspond à une position d'ouverture maximale du tampon 6, dans laquelle le voile 22 est oblique par rapport à la surface supérieure 12 et définit un angle obtus par rapport à sa position fermée. Le tampon 6 est déplaçable dans une position intermédiaire quelconque entre la position fermée et la position ouverte.The open position corresponds to a maximum open position of the buffer 6, in which the web 22 is oblique with respect to the upper surface 12 and defines an obtuse angle with respect to its closed position. The pad 6 is movable in any intermediate position between the closed position and the open position.

Tel que représenté sur la Figure 2, le regard de chaussée 2 comporte une charnière supplémentaire analogue à la charnière 24 et coaxiale avec celle-ci. La charnière supplémentaire est symétrique de la charnière 24 par rapport au plan I-I de coupe de la Figure 1. Seule la charnière 24, visible sur la Figure 1 et représentée en haut sur la Figure 2, sera décrite en détail par la suite.As shown on the Figure 2 , the roadway 2 comprises an additional hinge similar to the hinge 24 and coaxial with it. The additional hinge is symmetrical with the hinge 24 relative to the cutting plane II of the Figure 1 . Only the hinge 24, visible on the Figure 1 and represented at the top on the Figure 2 , will be described in detail later.

Tel que représenté sur la Figure 3, représentant le regard de chaussé 2 de la Figure 2 en l'absence d'organes de blocage 46 (voir ci-après), le charnon d'élément de recouvrement 28 de la charnière 24 présente en vue de dessus une forme en L. Il comprend un bras 29 s'étendant sensiblement radialement vers l'extérieur à partir du bord du voile 22, un tourillon 30 d'axe Y-Y disposé à l'extrémité libre du bras 29, et un ergot 31.As shown on the Figure 3 , representing the look of pavement 2 of the Figure 2 in the absence of locking members 46 (see below), the covering element knuckle 28 of the hinge 24 presents in top view a L-shape. It comprises an arm 29 extending substantially radially outwards from the edge of the web 22, a pin 30 of axis YY disposed at the free end of the arm 29, and a pin 31.

Le tourillon 30 possède une surface extérieure 30A en portion de cylindre d'axe Y-Y destinée à coopérer avec une surface d'articulation 26A du charnon de cadre 26.The pin 30 has an outer surface 30A in a Y-Y axis cylinder portion intended to cooperate with a hinge surface 26A of the frame hinge 26.

L'ergot 31 prolonge le tourillon 30 suivant l'axe Y-Y en faisant saillie latéralement du bras 29, ce qui confère au charnon d'élément de recouvrement 28 sa forme en L. L'ergot 31 possède un méplat 31A.The lug 31 extends the trunnion 30 along the Y-Y axis by projecting laterally from the arm 29, which gives the lining piece knuckle 28 its L-shape. The lug 31 has a flat part 31A.

Le charnon de cadre 26 comporte une ouverture de charnon 32 supérieure permettant l'engagement du charnon d'élément de recouvrement 28 dans le charnon de cadre 26.The frame knuckle 26 has an upper knuckle opening 32 for engaging the covering member knuckle 28 in the frame knuckle 26.

L'ouverture de charnon 32 présente une forme en L correspondant à celle du charnon d'élément de recouvrement 28. Elle comprend un canal 33 s'étendant dans le cadre 4 à partir du bord de l'ouverture 8 pour le passage du bras 29 et du tourillon 30, et une encoche 34 prolongeant le canal 33 pour le passage de l'ergot 31.The knuckle opening 32 has an L shape corresponding to that of the covering member knuckle 28. It comprises a channel 33 extending in the frame 4 from the edge of the opening 8 for the passage of the arm 29 and of the trunnion 30, and a notch 34 extending the channel 33 for the passage of the lug 31.

L'encoche 34 est délimitée entre un rebord 35 du cadre 4 et la paroi de cadre extérieure 20 en vis-à-vis.The notch 34 is delimited between a flange 35 of the frame 4 and the outer frame wall 20 vis-à-vis.

En position fermée du tampon 6, le rebord 35 recouvre en partie l'ergot 31 du charnon d'élément de recouvrement 28 engagé dans le charnon de cadre 26.In the closed position of the buffer 6, the flange 35 partly covers the lug 31 of the covering element knuckle 28 engaged in the frame knuckle 26.

En référence à la Figure 1, le rebord 35 et le méplat 31A de l'ergot 31 sont agencés de façon que l'ergot 31 puisse traverser l'encoche 34 uniquement lorsque le tampon 6 se trouve dans une position intermédiaire de dégagement dans laquelle le voile 22 réalise avec le plan PS-PS un angle d'environ 90°. Dans cette position de dégagement, les charnons 26, 28 peuvent être dégagés l'un de l'autre selon une direction s'étendant perpendiculairement à l'axe d'articulation Y-Y, permettant ainsi d'extraire le tampon 6 du cadre 4.With reference to the Figure 1 , the rim 35 and the flat portion 31A of the lug 31 are arranged so that the lug 31 can pass through the notch 34 only when the buffer 6 is in an intermediate position of disengagement in which the web 22 realizes with the plane PS-PS an angle of about 90 °. In this release position, the knuckles 26, 28 can be disengaged from one another in a direction extending perpendicularly to the hinge axis YY, thus making it possible to extract the buffer 6 from the frame 4.

En position d'ouverture maximale du tampon 6, le méplat 31A est en appui contre la surface inférieure du rebord 35, de sorte que l'ergot 31 et le rebord 35 forment une butée à l'ouverture.In the maximum open position of the buffer 6, the flat part 31A bears against the lower surface of the rim 35, so that the lug 31 and the flange 35 form a stop at the opening.

Le cadre 8 délimite par ailleurs, au-dessous de la charnière 24, une cavité 38 s'étendant jusqu'à la surface inférieure 14 et débouchant à l'extérieur du cadre.The frame 8 further defines, below the hinge 24, a cavity 38 extending to the bottom surface 14 and opening out of the frame.

Le regard de chaussée 2 comporte en outre un élément de blocage 40 adapté pour bloquer le dégagement du charnon d'élément de recouvrement 28 du charnon de cadre 26 en particulier lorsque le tampon 6 se trouve dans la position de dégagement. La mise en place de l'élément de blocage 40 s'effectue par le dessous du cadre 4, en l'introduisant à travers la cavité 38 lorsque le tampon est en position ouverte.The manhole 2 further comprises a blocking element 40 adapted to block the disengagement of the covering element knuckle 28 from the frame hinge 26, in particular when the buffer 6 is in the disengagement position. The establishment of the locking element 40 is effected by the underside of the frame 4, by introducing it through the cavity 38 when the buffer is in the open position.

Cet élément de blocage 40 est représenté en détail sur les Figures 4 et 5. Il comporte un corps de base 42, un pied 44 et deux organes de blocage 46.This blocking element 40 is shown in detail on the Figures 4 and 5 . It comprises a base body 42, a foot 44 and two locking members 46.

Le corps de base 42 est une plaque sensiblement en forme de trapèze ayant deux projections 42A sur sa grande base.The base body 42 is a substantially trapezoidal plate having two projections 42A on its large base.

Le pied 44 est une plaque faisant perpendiculairement saillie du corps de base 42 à sa petite base.The foot 44 is a plate perpendicularly projecting from the base body 42 to its small base.

Un organe de blocage 46 est disposé à l'extrémité de chaque projection 42A et fait perpendiculairement saillie de cette projection. Les organes de blocage 46 s'étendent d'un côté du corps de base 42 opposé au côté du pied 44. Un organe de blocage 46 est associé à la charnière 24 tandis que l'autre organe de blocage 46 est associé à la charnière supplémentaire.A locking member 46 is disposed at the end of each projection 42A and perpendicularly protrudes from this projection. The locking members 46 extend from one side of the base body 42 opposite the side of the foot 44. A locking member 46 is associated with the hinge 24 while the other locking member 46 is associated with the additional hinge .

Le cadre 4 délimite pour chaque charnière un logement 48 (Figure 1) adjacent à l'ouverture de charnon 32 et ayant une forme complémentaire à celle de l'organe de blocage 46 associé.The frame 4 defines for each hinge a housing 48 ( Figure 1 ) adjacent to the knuckle opening 32 and having a shape complementary to that of the associated locking member 46.

Tel que représenté sur les Figures 1 et 2 illustrant le regard de chaussé 2 en présence de l'élément de blocage 40, lorsque l'organe de blocage 46 associé à la charnière 24 est reçu dans le logement 48, l'organe de blocage 46 chevauche l'encoche 34 de l'ouverture de charnon 32, et empêche ainsi le retrait de l'ergot 31. L'organe de blocage 46 s'oppose de ce fait au dégagement du charnon d'élément de recouvrement 28 du charnon de cadre 26 même si le tampon 6 est dans sa position de dégagement.As shown on the Figures 1 and 2 illustrating the pavement facing 2 in the presence of the locking element 40, when the locking member 46 associated with the hinge 24 is received in the housing 48, the locking member 46 overlaps the notch 34 of the opening 32, and thus prevents the withdrawal of the lug 31. The locking member 46 is therefore opposed to the release of the covering element knuckle 28 of the frame hinge 26 even if the buffer 6 is in its position. release position.

La position dans laquelle l'organe de blocage 46 est situé dans le logement 48 est montrée à la Figure 1, et la description qui suit se réfère à cette position. Une partie du corps de base 42 est reçu dans la cavité 38.The position in which the locking member 46 is located in the housing 48 is shown in FIG. Figure 1 and the following description refers to this position. Part of the base body 42 is received in the cavity 38.

Le pied 44 est dirigé radialement vers l'extérieur de l'axe central de cadre X-X et s'étend en-dessous de la surface de cadre inférieure 14. De plus, le pied 44 chevauche radialement la paroi de cadre extérieure 20 et s'étend partiellement à l'extérieur de la paroi de cadre extérieure 20.The foot 44 is directed radially outwardly of the central frame axis XX and extends below the lower frame surface 14. In addition, the foot 44 radially overlaps the outer frame wall 20 and extends partially outside the outer frame wall 20.

A l'état installé, le pied 44 et la partie inférieure du corps de base 42 sont enrobés entièrement par du matériau de scellement 16.In the installed state, the foot 44 and the lower part of the base body 42 are completely encapsulated by sealing material 16.

La conception du corps de base 42 et du pied 44 est particulièrement avantageuse étant donné que, dans le cas d'une tentative d'arrachement des organes de blocage 46, par exemple par l'introduction d'un levier entre les organes de blocage 46 et les logements 48, le matériau de scellement 16 est sollicité principalement en compression au niveau du pied 44. En conséquence, l'élément de blocage 40 résiste à des grandes forces.The design of the base body 42 and the foot 44 is particularly advantageous since, in the case of an attempted tearing of the locking members 46, for example by the introduction of a lever between the locking members 46 and the housings 48, the sealing material 16 is biased mainly in compression at the foot 44. As a result, the locking member 40 withstands high forces.

En outre, le fait que le pied 44 s'étende radialement vers l'extérieur permet de le concevoir avec une grande surface sans qu'il interfère avec l'ouverture à couvrir par le regard, ce qui augmente encore la sécurité.In addition, the fact that the foot 44 extends radially outwardly allows to design it with a large area without interfering with the opening to be covered by the gaze, which further increases safety.

Enfin, l'élément de blocage 40 peut être utilisé avec des regards existants et ne nécessite pas de modification du cadre.Finally, the locking element 40 can be used with existing eyes and does not require modification of the frame.
