Device for signalling closing off of at least one traffic lane on a roadway which comprises a plurality thereof in the same direction

摘要

This device is of the type consisting of a trailer (2) supporting at least one panel (7) of the arrow (7a), video sign and/or luminous message (7b) type of large size. Each side face (2a) of the chassis of this trailer (2) supports a panel (12), on the outer face of which directional chevrons (13) are painted and which is articulated by its posterior end to the corresponding posterior corner (14) of the trailer (2) so that it can occupy either a deployed position for contributing to the marking of a road narrowing zone, or a retracted position by folding back against the side face (2a) of the trailer, whereas its posterior face (2b) supports at least one posterior panel (15, 21, 22), articulated to one of the ends of the posterior face (2b) of the trailer (2) and capable of being either placed in extension or substantially in extension of one or other of the side panels (12) in order to contribute to the marking of one or two road narrowing zones, or to form the two sides of an equilateral triangle, the third side of which is formed by the rear face (2b) of the chassis of the trailer (2), or folded back against the posterior face of the chassis of the trailer in the retracted position.
