Patent

CA 2059714

The novel collapsible signalling post is provided with a weakened section characterized by an helical groove carved on the periphery of a tubular member to be mounted between an anchoring member and a rod member supporting a sign. The groove provides a weakened section adapted to split open along a portion thereof and upon bending caused by a lateral force exerted on the signalling post, the two end portions of the tubular member remain connected to each other by the unfolded spires formed between the helicoidal thread.

Poteau de signalisation frangible innovateur avec section affaiblie caractérisée par une rainure hélicoïdale gravée sur la périphérie d'un élément tubulaire à monter entre un élément d'ancrage et une tige supportant un panneau. La rainure donne une section affaiblie adaptée pour s'ouvrir le long de celle-ci et, quand elle est pliée sous l'effet d'une force latérale s'exerçant sur le poteau de signalisation, les deux parties d'extrémité de l'élément tubulaire demeurent reliées l'une à l'autre par les spires déployées qui sont formées entre les pas du filet hélicoïdal.
