HINGE ASSEMBLY AND CORRESPONDING ROAD DEVICE

摘要

The invention relates to a hinge assembly that includes a buffer (6) with a covering web (20) and a hinge (36) adapted for enabling an angular movement of the buffer (6) between an open position and a closed position, the hinge (36) including a first cam (38C) and a first counter-cam (38T), the first cam (38C) and the first counter-cam (38T) cooperating over a first angular range (a). The hinge (36) comprises an additional cam (44C; 144C) and an additional counter-cam (44T; 144T) operating over an additional angular range (ß; Y). The first angular range (a) and the additional angular range (ß; Y) overlap in an overlap angular range of at least 60° and in which the first cam and counter-cam and additional cam and counter-cam cooperates. The invention can be used for road manholes.
