Technical Examples
  1. A fixed frame (4) and a covering element (6), the frame (4) defining a frame plane (P-P). A first latch (30) has two latch surfaces (32, 34) which cooperate and which are inclined relative to the frame plane (P-P). The covering element (6) and the frame (4) comprise cooperating stop surfaces (52, 56) which limit a displacement of the lid (6) within the frame (4) in the frame plane (P-P). The stop surfaces (52, 56) are inclined relative to the frame plane (P-P) by an angle of from 30° to 80° and they maintain the covering element flat on the frame. Application to manhole covers for closing manholes.
