The device includes a base for supporting one or more vertical elements of a piece of street furniture (such as a lamp post, a traffic sign, an advertising post, etc.), wherein the base can include two parts or pieces nested together, one over the other, with a lower part anchored to the ground while the upper part is nested against the other by a pair of flanges. The relative movement between the upper and lower parts is restrained by the action of a brake including a plate which is fastened with a bolt and a nut to the upper part of the base. The plate has a recessed area at each end, where a nylon pellet is placed and whose breakage, when caused by a lateral force to the base, frees the upper part, allowing it to slide over the lower part. |
