Abstract

The present invention relates to a device for hinging a lid or cover to a frame, such as a manhole. The device is characterized in that it comprises two lateral pairs of links (6, 7) connecting the lid (2) to the frame (3) and allowing, when a lifting force is applied to the lid (2) occupying its lowered closed position, a couple to be applied to the lid (2) causing the lid (2) to come out of the frame (3) and causing the lid (2) to pivot about itself to its raised position in which it is held by the links (6, 7). The invention is applicable to roads.
