A Flexible Post Holder device having a flexible sign post holder that is suitable for use along roadways for marking the roadway by signs, the flexible post holder is comprised of a lower base plate that is permanently anchored to a hard ground surface. The lower base plate supports a resilient helical spring, the lower end of the helical spring that is mounted to the lower base plate and the upper end of the helical spring, being affixed to an upper base plate. Integral to the upper base plate is a cylindrical retaining member that is capable of receiving a sign post. In another embodiment, a tapered spike-like attachment plate can be secured to the lower base plate allowing the flexible post holder to be anchored into grassy and firmly packed ground soils. In both embodiments, the sign post is anchored to the cylindrical retaining member by helical threaded means. The sign post will yield when impacted by a vehicle, however, the resiliency of the helical spring will allow the sign post to be returned to its original vertical orientation.

orte-poteau souple constitué d'un porte-poteau de signalisation souple pouvant être utilisé le long des routes pour baliser ces dernières de panneaux de signalisation, le porte-poteau souple étant constitué d'une plaque de base inférieure ancrée en permanence à une surface dure au sol. La plaque de base inférieure soutient un ressort hélicoïdal déformable dont l'extrémité inférieure est fixée à la plaque de base inférieure et l'extrémité supérieure à la plaque de base supérieure. Un élément de retenue cylindrique solidaire de la plaque de base supérieure peut recevoir le poteau de signalisation. Dans une autre version, une plaque de fixation à tige conique peut être assujettie à la plaque de base inférieure permettant au porte-poteau souple d'être ancré dans des sols gazonneux et solidement tassés. Dans d'autres versions, le poteau de signalisation est ancré à l'élément de retenue cylindrique par des dispositifs à filetage hélicoïdal. Le poteau de signalisation ploiera sous le choc d'un véhicule, mais la souplesse du ressort hélicoïdal permettra au poteau de signalisation de reprendre sa position verticale d'origine.
