Abstract: 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.

Abstract: A road device such as a telecommunications access hatch having a frame that delimits an opening, a cover, a first hinge provided with a first cam and a first cam follower, which are designed to guide the cover between a released open position and a closed position, a first securing member and a first counterpart securing member that prevent the cover from lifting when in the closed position; and a first support bracket added on the frame that bears the first cam and the first securing member.

Abstract: The present invention relates to a sealing device, of the type including a base body suitable for sealing an opening, movable between an open position and a closed position, a thrust element having first and second ends, and a slack configuration and a tight configuration, and the first end of the thrust element being connected to the base body.

Abstract: The present fastener (36) for street ironwork includes a fastening or locking element (56). The fastener (36) includes a retaining foot (60) suitable for removably connecting the fastener (36) to a member of the street ironwork, via a receiving cavity (40) made in the member of the street ironwork by element of a shape-matching connection. The invention further relates to the use in attaching jacks to man hole covers.

Abstract: 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.

Abstract: This road device has a frame (4) that delimits an opening (8), a cover (6) that has a covering wall (14) extending along a wall plane (PV-PV), a first hinge provided with a first cam (24) and a first cam follower (26) which are designed to guide the cover between a released open position and a closed position, and securing means that prevent the cover from lifting, in the closed position, in a direction perpendicular to the wall plane. The securing means have a first securing member (34) and a first counterpart securing member (36). The road device has a first support bracket (42) added on the frame (4) and bearing the first cam (24) and the first securing member (34). Application to telecommunications access hatches.

Abstract: The invention relates to a sealing device which includes: a base body (30) suitable for sealing an opening (8), movable between an open position and a closed position; a thrust element (34) having first (36) and second (38) ends, and a tight configuration and a slack configuration, the first end (36) of the thrust element being connected to the base body (30). The sealing device also includes a linking element (42) connected to the base body (30) and connected to the second end (38) of the thrust element. The sealing device includes a bearing member (50). The linking element (42) allows the thrust element to change from the tight configuration the slack configuration and vice-versa.
