Definitions

  • the invention relates to a circular manhole cover with articulated half-buffers.
  • the manholes are, in general, composed of a frame fixed to the roadway and a removable buffer o To access the well closed by the manhole, it is necessary to remove the buffer. This operation is awkward, whatever the weight of the The same applies to the replacement of the buffer in the frame.
  • the object of the present invention is to provide a manhole cover which, combining the advantages of articulated pads and half-pads resting on three spans in V, without presenting any constructive or use disadvantages, and does not risk generating noises consecutive to bad bearings on the frame.
  • This look is of the type comprising, articulated on a frame, two half-pads each having three radial studs, respectively lateral and posterior, provided at their lower part with corners capable of resting on V-shaped positioning faces made in the ears of the frame.
  • each half-buffer passes through the posterior ear to which it is integral, while the posterior radial post is provided with an internal housing with cam profile whose profile is determined so , that in the closed position, the horizontal axis is not in contact with the housing, but that during opening, it controls the movement of this half-pad, first alone, then on the rest of the movement, in combination with the rear edge of the tampon coming to rest on the wall and on the bottom of the ear.
  • the shape of the housing for the axis therefore makes it possible to give a stable position to the corresponding half-buffer, both when it is in the open position and when it is in the closed position at rest on the V-shaped bearings.
  • the angle formed by the faces of each of the V-shaped housings of the ears is a few degrees less than that of the angle formed by the complementary faces of the corresponding tenon.
  • the contact faces of the different spans are adjusted to each other by matting, which improves the contact and the stability of the half-pad.
  • the energy communicated to it allows these studs to get caught in the V of the frame and thus ensure locking by jamming of this half-buffer.
  • this circular manhole is composed of a frame (2) and two half-buffers (3a-3b) having, in plan view from above, a semi-circular shape.
  • Each pad is provided with three radial studs, namely: a rear articulation stud (4) and two lateral positioning studs (5).
  • the longitudinal axis of the articulation stud (4) is perpendicular to the straight edge (6 ) of the corresponding half-pad, while the longitudinal axes of the two positioning studs (5) are substantially parallel to this straight edge.
  • the two positioning studs (4) are arranged in posterior radial lugs (7) of the frame (2 These two ears are diametrically opposed. As for the positioning studs (5), they penetrate into ears (8), also diametrically opposite and substantially offset by 90 ° with respect to those (7).
  • Each ear (8) is arranged to receive simultaneously the positioning pins (5) of the two half-eyes
  • the positioning studs (5) are provided with contact and positioning faces capable of cooperating with complementary faces formed in the ear (8) corresponding
  • these contact and positioning faces (9a-9b) form a wedge (9) capable of penetrating into the V-shaped housing (10) formed in the corresponding ear (8).
  • the hinge pin (7) is provided, at its base, with two inclined lateral faces (12) giving it a truncated V shape. These faces are intended to cooperate with inclined faces (13) delimiting a V in the bottom of the corresponding ear (7).
  • the angle formed by the faces of each of the V-shaped housings (10) of the ears (8), as well as that formed by the faces (13) of the ears (7), has a value which is a few degrees lower than that of the angle formed by the complementary faces, respectively (9a-9b) and (12), of the corresponding studs.
  • This arrangement allows the contact faces to form by themselves by matting and thus improves the stability of the gaze. Furthermore, it makes it possible to obtain a wedging effect contributing to keeping the half-buffers in the closed position, even when a heavy vehicle passes over the manhole.
  • each articulation pin (4) on the frame (2) is ensured by an axis (14), horizontal, and passing through said ear to which it is integral.
  • This axis can be attached or come from molding with the frame .
  • This axis crosses transversely a housing (15) of the tenon (4), housing whose internal wall has a cam-shaped profile the usefulness of which will be specified below.
  • the housing (15) communicates with the outside by a groove transverse (16) formed in its posterior part and whose opposite faces are separated by a distance (D) at least equal to that (d) separating two flat (14a), parallel and vertical, made on the axis (14).
  • the wall of the housing (15) is arranged so as to do not come into contact with the axis (14).
  • the tenon (4) is in contr support e the upper posterior edge (23) of the ear (7) and, by the face of its housing (15), against the posterior flat (14a) of the axis (14). Thanks to these two contacts, the half-buffer occupies a perfectly stable opening position which prevents it from accidentally closing.
  • the half-pad (3a) has an opening (25) for the passage of a pointed tool such as the pick of a pickaxe, while the half-pad (3b) is provided with a handle (26) facilitating its lifting.
  • the closing operation does not require retaining the half-pad, so that it can be carried out very quickly by simple pushing of this half-pad, which, moreover, facilitates the wedging of the positioning pins (5) in the V (10) and the locking of this half-pad .
  • this manhole cover is very easy to maneuver, both for opening and for closing, ensures the safety of personnel when they are in the open position, without the need for other accessories, and has, in the closed position, excellent stability preventing them to tip over when passing vehicles and, therefore, to generate noise.
