HINGE ASSEMBLY AND CORRESPONDING ROAD DEVICE |
摘要 |
This hinge assembly comprises a lid with a covering web and a hinge adapted for enabling an angular movement of the lid between an open position and a closed position, the hinge including a first cam and a first counter-cam, the first cam and the first counter-cam cooperating over a first angular range. The hinge comprises an additional cam and an additional counter-cam cooperating over an additional angular range. The first angular range and the additional angular range overlap over an angular overlap range that amounts to at least 60° and over the entire range of which both the first cam and counter-cam and the additional cam and counter-cam cooperate simultaneously. The device can be used for road manholes.
