摘要

#CMT# #/CMT# The sign has a fixation device with an open profile (6) defined by a dorsal wall (10). Two lateral blades (11, 12) and two edges (13, 14) partially close a front inlet of the profile. A screw has a head that slides in a groove of the profile. The profile has grooves (7, 8) that receive screw heads slidingly and lock the heads at rotation, respectively, where one of the screw heads has a section greater than the other screw head. #CMT#USE : #/CMT# Traffic sign. #CMT#ADVANTAGE : #/CMT# The open profile has grooves that receive screw heads slidingly and lock the heads at rotation, respectively, thus permitting mounting of the screw without any accessory, hence reducing number of components of the road sign. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a transversal view of a profile of a road sign. 6 : Open profile 7, 8 : Grooves 10 : Dorsal wall 11, 12 : Lateral blades 13, 14 : Edges.
