Definitions

  • the invention relates to a manhole cover according to the preamble of claim 1.
  • Such manhole covers must be secured in such a way that the grate does not jump out of the frame due to the impact of vehicles traveling over them and, if possible, cannot be removed by unauthorized persons.
  • a generic manhole cover is known from FR-A-2 456 169.
  • the frame shows vertically upward-pointing fingers with hooks at the ends, which protrude laterally over horizontal contact surfaces on a grate placed on the frame. The fingers are bent out sideways to remove the grate.
  • Such a fuse is inseparably connected to the grate and acts automatically, which is undesirable for types of use in which, for example, the shaft has to be opened frequently and on the other hand a fuse is unnecessary.
  • it secures the grate against unintentional removal, but leaves it play so that it moves under the influence of vehicles traveling over it, which on the one hand causes accelerated wear and on the other hand undesirable noise.
  • the object of the invention is to provide a generic manhole cover with a fuse which can be removed as quickly and conveniently as possible, so that the grate can be used with or without a fuse depending on the type of use.
  • the fuse should be designed so that it holds the grate in the frame with as little play as possible.
  • the type of fastening of the securing parts also avoids high mechanical loads on the grate material.
  • the shaft cover shown in FIGS. 1, 2 has a frame 1 with a two-part lower-lying support shoulder 2, on which a grate 3 rests.
  • the securing part 4a comprises a holding part 6 which is designed as an elastic tab extending obliquely from top to bottom and to which a locking part 7 is connected.
  • the frame 1 has a recess 8 on its underside, the base of which is formed by a locking surface 9.
  • the locking surface 9 can be inclined towards the edge of the recess 8. The locking part 7 and the locking surface 9 are in engagement with one another and thus secure the grate 3.
  • the second securing part 4b is preferably of the same design as the first securing part 4a, but it can also be replaced by another device, e.g. B. by a nose on the frame, which engages in a recess on the surface of the grate.
  • the manhole cover is unlocked in that the locking part 7 is withdrawn from the locking surface 9 with elastic deformation of the holding part 6. Then the grate 3 with the securing parts 4a, b can be easily lifted off. It is advantageous to form the security parts 4a, b for theft protection in such a way - in particular to dimension the holding part 6 - that sufficient deformation to unlock the grate 3 can only be achieved with a special tool, eg. B. at the end of the locking part 7, on the grate 3 supported pliers is possible. After dismantling the grate 3, the securing parts 4a, b can be easily removed.
  • the mounting of the grate is made easier by the fact that the frame is slightly beveled at the bottom. As soon as the grate has reached the closed position, the lock snaps into place by itself.
  • Metallic materials in particular spring steel and other types of steel or cast iron with nodular graphite, as well as corrosion-resistant plastics are particularly suitable as materials for securing parts.
