Definitions

  • 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.
  • Document FR-A-2 613 742 thus discloses manholes with tilting buffers 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.
  • 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.
  • the present invention relates to a manhole cover provided with a hinged device making it possible to overcome these drawbacks.
  • 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 with which the tampon is provided and which projects on the periphery of said tampon, the transverse dimension of said pivot perpendicular to the tampon being less than that of the opening towards the top of the housing whereas its transverse dimension parallel to the tampon is greater than that of the opening of the housing, in which the bottom of each housing, defined in the conditions of installation of the frame, has a through hole 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 is at an angle of 90 ° to its closed position .
  • the manhole cover according to the invention consists of a frame 1 and a buffer 2.
  • the frame 1 has in known manner an inner projection 3 capped for example with a soundproofing seal 4 made of elastomer.
  • the manhole cover is circular.
  • At least one housing 5 open upwards in the upper face of the frame 1 and opening into the interior of said frame.
  • 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.
  • 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.
  • 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 up to the external wall 15 of the frame, and is overhung, towards its upper end, by a lip 16 provided with a chamfer 24.
  • 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.
  • 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.
  • each pivot 19 has the general shape of a T dimensioned to cooperate with a housing 5 of the frame 1.
  • 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.
  • the part 20 on each side has in its first innermost half adjoining the buffer a stop 23.
  • 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.
  • 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.
  • the pivot 19 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.
  • the buffer 2 is locked in the vertical position.
  • 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.
