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 lifting of the pad relative to the frame by pivoting around the hinged device.
  • Each housing having the general shape of a T, practiced in a peripheral region of the frame has two separate parts.
  • the second part has a first portion located radially inward and adjoining the first portion, having in radial section a concave shape facing outward, and a second portion located radially outward, the bottom of which is connected continuously. with the bottom of the first portion.
  • the first portion is overhung by retaining lips which frame a free space and the second portion is open upwards over its entire length.
  • Each pivot having the general shape of a T has a connecting part corresponding to the leg of the T and a pivot shaft part corresponding to the crossbar of the T, having a substantially cylindrical shape.
  • Such a hinged device described in French patent application no. 2 613 742 allows an opening position of the tampon with an inclination of 15 to 20 ° relative to the vertical.
  • This type of gaze risks in certain configurations to close accidentally under the effect for example of a violent gale or a clumsiness of a passerby, 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 remedy this drawback.
  • the present invention relates more particularly to a hinged manhole cover consisting of a frame and a buffer, the frame being provided with at least one housing open upwards, the lateral ends of which are overhung by retaining lips. and opening towards the inside of the frame, each housing being intended to cooperate with a protruding pivot of the pad, thus authorizing the lifting of said pad relative to the frame by pivoting around the hinged device, characterized in that the pivot has, in section along a vertical plane passing through the pivot axis, when the tampon is in the closed position, a central part of thickness greater than that of the lateral parts which surround it.
  • 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 sound-absorbing seal 4 made of elastomer.
  • the pavement manhole 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.
  • the pad 2 has as many pivots 12 as the frame has housings 5.
  • Each pivot 12, having the general shape of a T in the embodiment shown, has a connecting part 13 extending radially and connected to the pad, and a pivoting shaft part 14 having a flat 15 extending over the entire upper surface parallel to the main faces of the pad 2.
  • the pivot shaft part 14 has, in section along a vertical plane passing through the pivot axis, when the plug is in the closed position, a central part 16 of thickness greater than that of the lateral parts 17 and 18 which frame it.
  • the pivoting shaft part 14 of the pad has a generally cylindrical shape and has two lateral recesses 19 and 20 whose size is substantially equal to that of the lips 9.
  • the recesses 19, 20 have a face 21 parallel to that of the plate 15 and and an oblique face 22 making an angle ⁇ of 130 to 140 ° relative to the upper face of the pivot 12.
  • the opening angle of the pad is then 40 to 50 ° relative to the vertical, which avoids any risk of accidental closing.
