Definitions

  • the present invention relates to manhole covers and more particularly to the keys which serve for locking the covers of these manholes in their frames.
  • Pavement manholes consist of a circular frame in which a cover, also circular, is fitted, provided with radial lugs.
  • the frame has cells in which the tabs of the cover are housed during assembly. A rotation of the cover makes it possible to block the tabs in the cells and to maintain the cover in its final position.
  • the object of the present invention is to remedy this drawback.
  • the device according to the invention ensures the locking of a manhole cover tightened by rotation on its frame provided with one or more radial legs located at an upper level and one or more radial legs located at a lower level, the device comprising one or more locking keys locking the cover against rotation, which are composed of two parts, an upper straight part and a lower curved part which are introduced by a single movement from top to bottom in their blocking position in frame housings by laterally blocking at the same time by their upper part the upper clamping tabs and by their lower part the lower clamping lugs.
  • Figure 1 is a top view of a cover, placed in its frame.
  • Figure 2 is a perspective view of the key and its housing.
  • Figure 3 is a side view of the key and the manhole in section A-A.
  • the locking device is applied to a manhole cover comprising a circular frame (1) which receives a cover (2), blocked by one or more keys (3), engaged in housings (4) provided in this context (1).
  • the cover (2) rests by its circular edge (5) on the peripheral rim (6) of the frame (1) with the interposition of a seal (7), and comprises a number of clamping lugs (8) coming from the face lower (9) of the rim (6) of the frame (1).
  • the cover (2) further comprises a corresponding number of radial lugs (10) allowing blocking at the upper level by the keys (3).
  • the peripheral rim (6) of the frame (1) is provided with a corresponding number of cutouts, which allow the passage of the clamping tabs (8) when the cover (2) is installed.
  • the frame (1) has a corresponding number of rectangular housings (11) above the passage cutouts. These housings (11) have a dimension in the radial direction corresponding approximately to the length of the radial lugs (10).
  • the locking keys (3) consist of two integral parts, one (12) upper is intended to be placed in position in the housing (11) while the other (13) has just been housed in a housing ( 4) provided in frame (1).
  • This housing (4) is curved and has the same profile as the lower part (13) of the key (3).
  • the width of the housing (11) corresponds to the sum of the widths of the upper part (12) of the key (3) and of the radial tab (10).
  • the key (3) has an inclined surface (14) relative to its upper surface (15) allowing the insertion of a flat tool between the edge (16) of the housing (11) and the inclined surface (14) for the disassembly.
  • the cover (2) is placed above the frame (1), the clamping tabs (8) being located above the cut-outs in the peripheral flange (6).
  • the cover is lowered, putting the upper radial lugs (10) in place inside the housings (11).
  • the clamping lugs (8) are brought into contact with the lower edges (9) of the frame (1).
  • This rotation is limited by the radial lugs (10) moving in the housings (11) and coming into contact with the side wall of this housing (11). In this position the cover is tight but not locked.
  • the keys (3) are then inserted from top to bottom in the housings (11) and the key (3) locks the cover (2) as well by lateral contact of the part (13) with the clamping tab (8) only by lateral contact of the part (12) with the upper radial tab (10).
  • the keys (3) are held by gravity in the locked position and an upper planar surface of the entire manhole is ensured.
  • a flat tool is inserted between the edge (16) and the surface (14) of the key (3) to blow it up in an easy movement.
  • the key is simple to manufacture, either by cutting from a sheet, or by cutting a profile, or by foundry.
