Definitions

  • the invention relates to manhole covers composed of a frame with internal collar, circular or not, and a single articulated buffer.
  • French patent application FR-A-2 603 631 and French patent FR-A-2 581 103 describe two manholes of this type in which the annular seal has an open "C" cross section and is designed to cover the edge. internal of the collar, having a complementary profile.
  • a first drawback of this mounting method is that the installation of the seal, which is carried out only after sealing the frame in the ground, is sometimes disturbed by overflows of the fixing cement on the internal flange.
  • the present invention aims to provide a buffer manhole cover, articulated and waterproof, which overcomes these drawbacks.
  • This pavement manhole is of the type in which the articulation is ensured by a radial stud cooperating with a pivot formed in a radial ear of the frame.
  • its damping joint has an inverted "T" cross section, the rod of which is engaged with wedging in a groove surrounding an internal rib placed on the periphery of the tampon and opening out from the underside of the tampon and the bearing is able to come to bear on the frame flange, this joint being associated with means for guiding the closing pivot of the tampon, in its tilting phase, and means for guiding the introduction of the rib of the tampon into the opening formed by the flange of the frame.
  • the fixing to the cement of the frame does not require any particular precaution, provided that the upper face of the collar, constituting the bearing face of the joint, is released and, on the other hand, the seal is protected against bumps and scratches due to the passage of personnel and equipment.
  • the means for guiding the pivoting of the tampon and the introduction of its rib into the frame force the tampon to be positioned perfectly in the frame, before it reaches the final closed position, and thus avoid that the seal comes into contact with a surface other than its bearing face, that is to say with a surface that can cut it or damage it.
  • the means for guiding the pivoting of the tampon consist of its tenon which, of the type provided with an opening whose edges cooperate with a pivot formed in the ear to control all or part of its pivoting during tilting, comprises, on the one hand, a lower external cam-shaped angle, capable of cooperating, during the phase of tilting of the buffer which is controlled by the edges of the light, with at least one ear ramp, ramp which is inclined up and down and from the inside to the outside and, on the other hand, a lower interior angle, also cam-shaped and able to cooperate with the outer edge of the collar of the frame, at the end of closing, to move the post outwards, free the edge of its lumen from contact with the pivot and position the rib of the pad in the axis of the frame.
  • the pivoting of the buffer is controlled over most of its travel, but ceases to be controlled as soon as its rib is able to take over. Thanks to this arrangement, when the pad is in the closed position, the means for guiding its post are inoperative and it rests with all its weight, without any constraint but with interposition of the seal, on the internal flange of the frame.
  • the opening of the frame flange is flared upward to form a final centering member for the rib of the pad.
  • This look is therefore composed of a circular frame 2 and a buffer 3.
  • the buffer is provided with a radial post 4 which is articulated on a pivot in two parts 5a-5b arranged transversely in an ear 6 projecting from the frame 2 .
  • each of the elements 5a-5b of the tenon has two lateral flats 7 and a semi-cylindrical lower face 8.
  • the tenon 4 of the pad 3 comprises, in known manner, an internal opening 9, the edges are shaped as ramps and are intended to cooperate with the cylindrical face 8 of the elements 5a and 5b of the post, during the pivoting of closure of the pad 3.
  • the pad 3 has an inner cylindrical rib 10 which provides its reinforcement.
  • the aforementioned rib 10 is surrounded by a circular groove 12 emerging from the inner face of the pad and constituting a housing for a damping joint 13 having an inverted "T" section.
  • the rod of this "T” is forcibly engaged in the housing 12, while its transverse bar constitutes a sealing surface while coming to bear on the internal flange 14 of the frame 2.
  • This damping joint is associated with means for guiding the closing tilting of the frame and with means for centering the rib 10 of the pad 3.
  • the means for guiding the tilting of the pad 3 are arranged on its tenon 4 and comprise, on the one hand, a cam shape 15 formed on the lower external corner of this pad and a cam shape 16 formed on the lower corner interior.
  • the ramp 15 is intended to cooperate with two faces 17 formed in the bottom of the ear 10 and inclined up and down towards the outside, as shown in FIGS. 2 to 6 and 7.
  • FIG. 3 shows that when the tampon is in the open position, its seal 13 is perfectly protected against any deterioration by the rib 10 which projects in relation to it.
  • this buffer can be released from the frame very easily if the operator takes care to arrange the lateral lights 20, which is provided with its stud 4, at the level of the elements 5a-5b of the pivot and pull the buffer upwards. 3. Under these conditions, the web of material 22, separating the two openings 20, passes without difficulty in the interval 23 between the two elements 5a-5b of the pivot. It is obvious that the replacement of the tampon is carried out in reverse order.
  • the ramp 16, formed on the lower internal angle of the lug 4 comes into contact with the angle 18 of the flange 14 and causes the displacement of the pad in the direction of the arrow 25, the loss of contact of the light 9 with the cylindrical profile 8 of the pivot elements 5a-5b, and, consequently, the end of the control ensured by the contact of these elements.
  • the movement of the gaze, in the direction of the arrow 25, ensures the pre-centering of the rib 10 of the pad relative to the flange 14. It follows that, when the rib 10 enters the internal opening of the collar, it is practically centered relative to the axis of this collar. To take account of the manufacturing clearances, the final centering is ensured by contact of the external angle 26 of the rib 10 with the internal sloping face 27, flaring upwards, of the flange 14.
  • the buffer 3 means which ensure a decomposition of this positioning, the buffer is perfectly centered when it comes to the closed position, which guarantees good support of the seal 13 on the flange 14 and avoids any risk of damage to this seal.
  • the damping seal can also provide a sealing function, in particular against odors.
  • the device according to the invention is not limited to circular manholes but applies, of course, to all manholes, whatever their section, rectangular, square or other.
