Patent

CA 2376440

A breakaway sign post assembly (30) is disclosed as including a sign support post (32), an anchoring post (34) and a breakaway collar (100). The breakaway collar (100) includes a sidewall (102) which surrounds the sign support post (32). The sidewall (102) includes at least one substantially vertical line of weakness (120) configured to facilitate a portion of the sidewall (102) to give way. The sidewall (102) retains the sign support post (32) in a manner to define a fulcrum (134) about which the sign support post (32) turns when a vehicle impacts and exerts a lateral force at an impact location, with the fulcrum (134) being positioned below the impact location so that the support post (32) will swing generally away from the vehicle.

L'invention porte sur un ensemble poteau indicateur frangible (30), qui comprend un support du poteau indicateur (32), un poteau d'ancrage (34) et un collier de rupture (100). Le collier de rupture (100) présente une paroi latérale (102) entourant le support du poteau indicateur (32). La paroi latérale (102) comprend au moins une ligne de faiblesse (120) sensiblement verticale conçue pour faciliter la rupture d'une partie de la paroi latérale (102). La paroi latérale (102) retient le support du poteau indicateur (32) de façon à délimiter un point d'articulation (134) autour duquel le support du poteau indicateur (32) tourne lorsqu'il est heurté par un véhicule et qu'une force latérale s'exerce au niveau d'un point d'impact, le point d'articulation (134) étant placé sous le point d'impact si bien que le support du poteau indicateur (32) est généralement balancé loin du véhicule.
