Description

La présente invention a pour objet un regard de chaussée pourvu d'un dispositif à charnière liant, de manière amovible, le tampon au cadre et autorisant le soulèvement du tampon par rapport au cadre par pivotement autour du dispositif à charnière, le tampon étant verrouillé en position d'ouverture.The subject of the present invention is a manhole cover provided with a hinged device which removably links the pad to the frame and authorizes the raising of the pad relative to the frame by pivoting around the hinged device, the pad being locked in open position.

On connaît les regards de chaussée à tampon basculant montés sur au moins une charnière et qui présentent à cet effet au moins un pivot saillant latéralement. Chaque pivot s'engage dans un logement respectif dont est muni le cadre.We know the manholes with tilting buffer mounted on at least one hinge and which have for this purpose at least one pivot projecting laterally. Each pivot engages in a respective housing with which the frame is provided.

L'ouverture d'un tel regard s'effectue par pivotement du tampon autour du dispositif à charnière jusqu'à ce que le tampon dépasse sa position verticale et que chaque pivot vienne en butée sur des lèvres de retenues dont est munie chaque charnière. Le tampon en position d'ouverture forme alors un angle d'environ 105 à 110° par rapport à sa position de fermeture et tient dans cette position sous l'effet de son propre poids.The opening of such a manhole is effected by pivoting the pad around the hinged device until the pad exceeds its vertical position and each pivot comes into abutment on the lips of retentions with which each hinge is provided. The tampon in the open position then forms an angle of approximately 105 to 110 ° relative to its closed position and holds in this position under the effect of its own weight.

Ce type de regard risque dans certaines configurations de se refermer intempestivement, sous l'effet par exemple d'un coup de vent violent ou d'une maladresse d'un passant, en particulier dans le cas de tampons particulièrement légers.In certain configurations, this type of gaze risks closing unexpectedly, under the effect for example of a strong gale or a clumsiness of a passer-by, in particular in the case of particularly light pads.

En effet, il suffit de faire pivoter le tampon de 15 à 20° pour que celui-ci dépasse sa position verticale et se referme violemment sous l'effet de son poids.Indeed, it suffices to rotate the pad 15 to 20 ° so that it exceeds its vertical position and closes violently under the effect of its weight.

Compte tenu du fait que les regards de chaussée recouvrent des cheminées de visite, pour des raisons élémentaires de sécurité, le tampon ne doit pas se refermer intempestivement.Taking into account the fact that the manholes cover inspection chimneys, for elementary security reasons, the stamp must not close unexpectedly.

Il est connu d'utiliser des dispositifs de verrouillage du tampon par l'interposition par exemple de cales ou de barres de blocage.It is known to use devices for locking the tampon by interposing, for example, shims or blocking bars.

De tels dispositifs, s'ils verrouillent effectivement le tampon en position ouverte, sont toutefois contraignant pour l'utilisateur. En effet il faut se munir des cales ou des barres de blocage et les positionner après ouverture du tampon. Très souvent, par un excès de confiance, l'utilisateur néglige l'opération de verrouillage.Such devices, if they effectively lock the buffer in the open position, are however binding on the user. Indeed it is necessary to provide shims or blocking bars and position them after opening the buffer. Very often, by overconfidence, the user neglects the locking operation.

La présente invention concerne un regard de chaussée pourvu d'un dispositif à charnière permettant de s'affranchir de ces inconvénients.The present invention relates to a manhole cover provided with a hinged device making it possible to overcome these drawbacks.

La présente invention concerne plus particulièrement un regard de chaussée à charnière constitué d'un cadre et d'un tampon, le cadre étant muni d'au moins un logement ouvert vers le haut et débouchant vers l'intérieur du cadre, chaque logement étant destiné à coopérer avec un pivot dont la dimension transversale perpendiculaire au tampon est inférieure à celle de l'ouverture vers le haut du logement et dont la dimension transversale parallèle au tampon est supérieure à celle de l'ouverture du logement, dans lequel le fond de chaque logement présente un trou débouchant sur toute sa longueur, de dimension légèrement supérieure à la dimension transversale perpendiculaire au tampon des pivots, permettant à chaque pivot de pénétrer dans le trou lorsque le tampon fait un angle de 90° par rapport à sa position de fermeture.The present invention relates more particularly to a hinged manhole cover comprising a frame and a buffer, the frame being provided with at least one housing open upwards and opening towards the interior of the frame, each housing being intended to cooperate with a pivot whose transverse dimension perpendicular to the pad is less than that of the upward opening of the housing and whose transverse dimension parallel to the pad is greater than that of the opening of the housing, in which the bottom of each housing has a hole opening out over its entire length, of dimension slightly greater than the transverse dimension perpendicular to the pad of the pivots, allowing each pivot to enter the hole when the pad makes an angle of 90 ° relative to its closed position.

Other characteristics and advantages will become apparent during the description which follows, given solely by way of example made with reference to the appended drawings in which:
  • - Fig. 1 is a top view of part of a road manhole frame according to the invention;
  • - Fig. 2 is a partial view in radial section along line II II of FIG. 1;

  • - Fig. 4 is a partial view in radial section showing the hinge, the pad being in the open position locked at 90 °.

Le regard de chaussée selon l'invention est constitué d'un cadre 1 et d'un tampon 2.The manhole cover according to the invention consists of a frame 1 and a buffer 2.

Le cadre 1 possède de manière connue une saillie intérieure 3 coiffée par exemple d'un joint insonorisant 4 en élastomère.The frame 1 has in known manner an inner projection 3 capped for example with a soundproofing seal 4 made of elastomer.

Dans l'exemple de réalisation représenté Fig. 1, le regard de chaussée est circulaire.In the embodiment shown in FIG. 1, the manhole cover is circular.

Dans l'épaisseur du cadre 1 est prévu au moins un logement 5 ouvert vers le haut dans la face supérieure du cadre 1 et débouchant vers l'intérieur dudit cadre.In the thickness of the frame 1 is provided at least one housing 5 open upwards in the upper face of the frame 1 and opening into the interior of said frame.

Dans la description, on se contentera d'un cadre muni d'un seul logement 5.In the description, we will be satisfied with a frame provided with a single housing 5.

Dans l'exemple de réalisation représenté, le logement 5 a la forme générale d'un T en vue de dessus. Une partie 6 dudit logement situé vers l'intérieur, constituant la jambe du T, a une profondeur moindre que le reste du logement. La largeur de la première moitié 7 de la partie 6 jouxtant la saillie 3 est supérieure à celle de sa seconde moitié 8.In the embodiment shown, the housing 5 has the general shape of a T when viewed from above. Part 6 of said housing located inward, constituting the leg of the T, has a lesser depth than the rest of the housing. The width of the first half 7 of the part 6 adjoining the projection 3 is greater than that of its second half 8.

Une partie 9 située vers l'extérieur constitue la barre transversale du T. Elle présente deux zones distinctes : une première zone 10 jouxtant la partie 6, ayant en section radiale un contour sensiblement circulaire, et dont les extrémités sont surplombées par des lèvres 11 non chanfreinées qui encadrent un espace libre prolongeant la partie 6 ; et une seconde zone 12, située le plus vers l'extérieur, de même dimension longitudinale que la zone 10, et présentant une ouverture 13 vers le haut sur tout sa longueur.A part 9 located towards the outside constitutes the transverse bar of the T. It has two distinct zones: a first zone 10 adjoining the part 6, having in radial section a substantially circular outline, and the ends of which are overhung by lips 11 not chamfers that frame a free space extending part 6; and a second zone 12, located furthest outwards, of the same dimension longitudinal than zone 10, and having an opening 13 upwards over its entire length.

Le fond du logement 5, au niveau de la zone 10, présente, sur toute sa longueur un trou débouchant 14, puis présente une profondeur décroissant jusqu'à la paroi externe 15 du cadre, et est surplombé, vers son extrémité supérieure, par une lèvre 16 munie d'un chanfrein 24.The bottom of the housing 5, at the level of the zone 10, has, over its entire length, a through hole 14, then has a decreasing depth to the outer wall 15 of the frame, and is overhung, towards its upper end, by a lip 16 provided with a chamfer 24.

Le tampon 2 possède, de manière connue une surface d'appui annulaire périphérique 17 destinée à reposer sur la saillie 3 recouverte du joint 4, ainsi qu'une jupe 18 faisant saillie sous sa face inférieure. La jupe 18 porte contre le joint 4 et empêche le tampon 2 d'être déplacé par rapport au cadre 1 lorsque le tampon 2 est en position de fermeture.The pad 2 has, in known manner a peripheral annular bearing surface 17 intended to rest on the projection 3 covered with the seal 4, as well as a skirt 18 protruding under its underside. The skirt 18 bears against the seal 4 and prevents the pad 2 from being moved relative to the frame 1 when the pad 2 is in the closed position.

Le tampon 2 présente autant de pivots 19 que le cadre ne présente de logements 5. Chaque pivot 19 fait saillie sur la périphérie du tampon 2.The pad 2 has as many pivots 19 as the frame does not have housings 5. Each pivot 19 projects from the periphery of the pad 2.

Dans la description, on se contentera d'un tampon muni d'un seul pivot 19. La dimension transversale perpendiculaire au tampon 2 des tétons 19 est inférieure à celle du trou 14 du logement 5, et la dimension transversale parallèle au tampon 2 des tétons 19 est supérieure à celle du trou 14 du logement 5 du cadre 1.In the description, we will be satisfied with a pad provided with a single pivot 19. The transverse dimension perpendicular to the pad 2 of the studs 19 is less than that of the hole 14 of the housing 5, and the transverse dimension parallel to the pad 2 of the studs 19 is greater than that of the hole 14 of the housing 5 of the frame 1.

Dans l'exemple de réalisation, chaque pivot 19 a la forme générale d'un T dimensionné pour coopérer avec un logement 5 du cadre 1.In the exemplary embodiment, each pivot 19 has the general shape of a T dimensioned to cooperate with a housing 5 of the frame 1.

Le pivot 19 possède une partie de liaison 20 correspondant à la jambe du T, s'étendant radialement et raccordé au tampon, et une partie d'arbre de pivotement 21 correspondant à la barre transversale du T.The pivot 19 has a connecting part 20 corresponding to the leg of the T, extending radially and connected to the pad, and a pivot shaft part 21 corresponding to the crossbar of the T.

La partie 20 de chaque côté présente dans sa première moitié la plus intérieure jouxtant le tampon une butée 23.The part 20 on each side has in its first innermost half adjoining the buffer a stop 23.

La partie 21 a une forme générale sensiblement cylindrique avec un diamètre inférieur au diamètre de la première zone 10 de section semi-circulaire du logement 5 du cadre 1. Elle présente un plat 22 formé longitudinalement sur toute sa longueur, s'étendant parallèlement aux faces principales du tampon 2.The part 21 has a generally substantially cylindrical shape with a diameter less than the diameter of the first zone 10 of semi-circular section of the housing 5 of the frame 1. It has a plate 22 formed longitudinally over its entire length, extending parallel to the faces main buffer 2.

La dimension transversale de la partie 21, perpendiculairement au plat 22, est inférieure à l'ouverture 13 vers le haut du logement 5, et sa longueur est telle que les faces externes présentent un jeu minimal avec les faces extrêmes du logement afin d'autoriser le libre pivotement du tampon 2 par rapport au cadre 1, mais empêchant le coincement dudit tampon lors de son soulèvement.The transverse dimension of the part 21, perpendicular to the flat 22, is less than the opening 13 towards the top of the housing 5, and its length is such that the external faces have minimal play with the end faces of the housing in order to allow the free pivoting of the buffer 2 relative to the frame 1, but preventing the jamming of said buffer during its lifting.

Lorsque le tampon 2 est en position de fermeture sur le cadre 1, le pivot 19 ne présente aucun point de contact avec les parois du logement 5, afin d'éviter tout heurt bruyant du tampon contre le cadre lors du passage d'un véhicule. Dans cette position, la partie 21 d'arbre de pivotement s'étend, au moins en partie, sous les lèvres en surplomb 11, lesquelles s'opposent donc à la sortie du pivot 19 hors du logement 5.When the pad 2 is in the closed position on the frame 1, the pivot 19 has no point of contact with the walls of the housing 5, in order to avoid any noisy collision of the pad against the frame during the passage of a vehicle. In this position, the pivot shaft part 21 extends, at least in part, under the overhanging lips 11, which therefore oppose the exit of the pivot 19 from the housing 5.

Lorsque le tampon est basculé sous l'effet d'un couple appliqué en son milieu, le pivot 19 s'abaisse dans le logement 5 jusqu'à ce que la partie 21 d'arbre de pivotement soit verticale. Dans cette position, il descend dans le trou débouchant 14 du logement 5. Simultanément, les butées 23 du tampon 2 glissent derrière les lèvres 11 du cadre 1.When the pad is tilted under the effect of a torque applied in the middle, the pivot 19 lowers in the housing 5 until the part 21 of the pivot shaft is vertical. In this position, it descends into the through hole 14 of the housing 5. Simultaneously, the stops 23 of the pad 2 slide behind the lips 11 of the frame 1.

Ainsi, le tampon 2 est verrouillé en position verticale.Thus, the buffer 2 is locked in the vertical position.

A l'effort horizontal tentant de fermer le tampon s'oppose un couple C s'exerçant d'une part contre les lèvres 11 et d'autre part contre la paroi du trou 14 en contact avec le plat 22.A horizontal force C trying to close the buffer is opposed, acting on the one hand against the lips 11 and on the other hand against the wall of the hole 14 in contact with the plate 22.

Pour refermer le tampon, il suffit de le soulever légèrement afin de dégager le pivot 19 du trou 14 et de faire pivoter le tampon.To close the pad, simply lift it slightly to release the pivot 19 from the hole 14 and rotate the pad.

Si l'on désire ouvrir le tampon 2 pour l'amener à une position faisant un angle supérieur à 90° par rapport à sa position de fermeture, il suffit de poursuivre le mouvement.If one wishes to open the pad 2 to bring it to a position making an angle greater than 90 ° relative to its closed position, it suffices to continue the movement.

En effet, de par le chanfrein 24 dont est munie la lèvre 16 du cadre, la réaction exercée par ladite lèvre est insuffisante pour s'opposer à l'ouverture complète du tampon. La partie 21 d'arbre de pivotement est rapelée par gravité jusqu'à venir en appui sur la paroi de la zone 10 de la partie 6 du logement 5 contre la face inférieure des lèvres en surplomb 11.Indeed, by the chamfer 24 which is provided with the lip 16 of the frame, the reaction exerted by said lip is insufficient to oppose the complete opening of the pad. The part 21 of the pivoting shaft is brought back by gravity until it comes to bear on the wall of the zone 10 of the part 6 of the housing 5 against the underside of the overhanging lips 11.
