The present invention is directed to street and highway posts generally used to support a signboard and more specifically to a connection adapted to be mounted between a lower post section and an upper post section. The connection is particularly adapted to prevent damage to the lower post section when the post is hit by a vehichle, and in many instances to also prevent damages to the upper post section.
The invention is particularly directed to a specific type of connection having a corrugated cross-section and more specifically, to a U-shape channel having two lateral flanges extending outwardly from the U-shaped channel. The connection is provided with a weakened linear section extending partly through the cross-section of the channel so as to allow the tilting of the upper post section relative to the lower post section and a subsequent tearing apart of the connection to maintain the upper post section linked to the lower post section.
