摘要

1. Road sign panel of the type formed by a series of sectional parts assembled to form on one face a wide flat surface designed to receive a reflective film covering this flat surface and having reference marks, each sectional part (A) having, in cross section, a main web (1) provided at one end with a U-shaped first part (18) having two branches (6 and 17), one of the latter being situated in the plane of the web (1) while the other branch (17) projects from another face of the web (1), and provided at the other end with a second U-shaped part (24) having two branches (8-23), one of the branches (8) being situated in the plane of the web (1) while the other (23) projects from the other face of the web (1), which is provided, on the same side as those branches of the U-shaped parts (18-24) which are opposite to those situated in the plane of the web (1), with a C-shaped sectional part (7) constituting a slide, the distance between the branches (8, 23) of the second U-shaped part (24) being such as to enable the branches of the first U-shaped part (18) to fit into it, and the branch (6) of the first U-shaped part (18) is situated in the plane of the web (1) and terminates in a point (11) slightly inclined towards the inside of the U and having a barb (12) directed towards the outside, while the other branch (17) of the said U-shaped part (18) comprises a corresponding point (19) with a barb (20) directed towards the outside of the U, while the branches (8-23) of the second U-shaped part each comprise at their free end a point (13 and 25 respectively) with a barb (14 and 26 respectively) directed towards the inside, while the branches (6-17) of the first U-shaped part (18) are provided, in the vicinity of the barbs (12, 20), with grooves (10, 21) corresponding to the barbs (14, 26) of the branches (8, 23) of the second U-shaped part (24), characterized by the fact that the internal faces of the branches of the said second U-shaped part (24) are provided with supports (16-27) for the free outer ends of the points (11, 19) of the branches of the first U-shaped part (18) while the part (7) of C-shaped cross section forming the slide is situated at an intermediate point half-way between the two U-shaped parts (18 and 24) and has its free edge situated in the plane of the branches (23) projecting from the other face of the web (1).
