<p>The subject of the invention is a self-locking double-face foldable support for signalling posts and panels of various types. A foldable support according to the invention comprises, on the one hand, a substantially rectangular base (1) and, on the other hand, a foldable framework (2) intended to support either a signalling panel or a signalling pole, or two signalling poles in opposition, one on each face of the foldable support. The base comprises two parallel longitudinal members (3d, 3g) joined together by end cross-pieces (4) and a central cross-piece (6) on which an inverted U-shaped piece (9), forming a base for the foldable framework, bears. A bolt (14) is fixed to the bottom of the foldable framework, so that it attaches it to the base (1) by simple weight action when the support is deployed. Unlocking occurs automatically when the foldable support is inclined forwards. One application is the construction of temporary road signalling panels. <IMAGE></p> |
