| 20120020729 | COVER FOR A ROAD SYSTEM DEVICE AND CORRESPONDING ROAD SYSTEM DEVICE - A cover for a road system device provided with a frame comprises: a blocking member and a base body defining a covering surface for the road system device, extending in a cover plane, and having a housing for receiving the blocking member. The housing and the blocking member are adapted for blocking the cover relative to the frame or to a neighboring cover. The housing is adapted to maintain the blocking member relative to the base body autonomously and to oppose a movement of the blocking member in a direction extending perpendicular to the cover plane and tending to move the blocking member away from the covering surface. The invention is applicable to access manholes for underground installations. | 01-26-2012 |
| 20120020728 | HINGE ASSEMBLY AND CORRESPONDING ROAD DEVICE - 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. | 01-26-2012 |
