Abstract (en)
[origin: US7160051B1] 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.
