Definitions

  • the invention relates to the manhole cover comprising one or more buffers articulated with respect to a frame and which can occupy either a closed position, in which the pad closes the opening made in this frame, or an open position, in which the pad releases this opening and is drawn up substantially vertically.
  • document EP-A-85433 describes a safety device for an articulated pavement manhole tampon comprising a frame which supports an axis of articulation of the buffer, and a gas spring, consisting of a body and a sliding rod, connected, on the one hand, by its body to a second axis of articulation to said frame, and, on the other hand, by its sliding rod to a lug of the buffer by a third articulation axis, the second articulation axis being located parallel and below the articulation of the buffer, so that the sliding rod of the gas spring moves away from the second axis of articulation when, by its opening, the pad is pivoted from a closed position to an open position.
  • a gas spring consisting of a body and a sliding rod
  • Such a device provides control of the movement of the tampon, but does not ensure its positive locking in the open position, so that accidents can still occur.
  • DE-B-1231590 also discloses a device for locking an insulating glazing unit comprising, articulated on the frame, a lever which, provided with an oblong slot in which a finger of the glazing frame can move, comprises at its free end, a manually operated locking lever for both locking and unlocking.
  • the present invention aims to provide a device for controlling the opening movement of the tampon, automatically ensuring, at the end of opening, the positive locking of the tampon, while being easily unlockable manually, and which, moreover, either reliable and inexpensive.
  • the device comprises a wedging lever of elongated shape, articulated at one of its ends around the articulation axis, which comprises on the one hand an oblong slot at its free end which cooperates with a finger integral with the pad, the finger being the extension of the third axis of articulation, a hook heavy, which is articulated there around a fourth axis of articulation so as to hang freely and to cooperate with the aforementioned finger so that, at the end of the opening movement and thanks to the positioning ensured by its own weight, it s '' grip under the finger forming an automatic setting of the buffer.
  • the lever straightens at the same time as it, and thanks to its articulation different from that of this tampon, describes by its free end a trajectory which gradually brings the hook, held in a substantially vertical position by its own weight, at the level of the pad finger. At the end of the movement, this hook engages under the finger, transforming the lever into a wedging leg.
  • the manhole cover is composed of a frame 2 and two trapezoidal pads 3. Each of the pads 3 is articulated around horizontal articulation axes 4 on yokes 5 projecting from the belt 2a of the frame 2.
  • Each buffer is associated with a gas spring 6 whose body 6a is articulated around a second axis 7, parallel to the previous one, disposed on a tab 8 projecting below the belt 2a of the frame.
  • the rod 6b of the gas spring 6 is articulated around a third axis 9 parallel to the previous ones, fixed on a tab 10 projecting from an inner lateral rib 11 of the corresponding pad 3.
  • the safety device is constituted by a lever 12 which, in this embodiment, is arranged on the other side of the rib 11 of the buffer with respect to the gas spring 6.
  • the lower end of this lever is articulated around of the second axis 7 for the gas spring, that is to say below the axis of articulation 4 of the buffer 3 on the frame 2.
  • This lever is provided near its free upper end with an oblong slot longitudinal 13 in which slides an extension 9a of the third articulation axis 9, of the gas spring 6 on the tab 10 of the pad 3.
  • the lever 12 is provided with a hook 14 articulated around a fourth hinge pin 15 on this lever.
  • This fourth axis is also parallel to the previous ones.
  • the hook 14 tends to remain below the fourth axis of articulation 15, and to occupy a position in which its body remains substantially vertical with its hook-shaped part open upwards and towards the extension 9a of the third axis 9.
  • the lever 12 When the tampon is in the closed position, and as shown in solid lines in FIG. 2, the lever 12 is arranged parallel to the gas spring 6 below the opening 21 of the frame 2.
  • the pad 3 When the pad 3 is brought into the open position by pivoting in the direction of the arrow 22 in FIG. 2, it is assisted by the gas spring 6, which extends and it drives the lever 12. During this pivoting and makes the gap E between the hinge pin 4, of the pad 3 on the frame 2, and the second hinge pin 7, of the lever 12 on the same frame, the terminating part of the lever provided with the hook 14, cuts the circular trajectory of the extension 9a of the axis 9. As a result, the hook is mounted under the finger formed by this extension, automatically ensuring the mechanical locking of the pad 3 in the open position shown in FIG. 3 .
  • the device according to the invention is particularly simple to make and inexpensive, considerably improves the safety of the personnel by ensuring the automatic locking of the pad 3 on opening and by preventing any untimely folding of the stamp 3 on the frame.
  • This device which has been described in the context of its application to a manhole comprising two trapezoidal pads, can of course be applied to manholes having pads of different shapes.
