Abstract: An impact absorbing sign post with quick change-out capability and method is provided. The impact absorbing sign post includes an upper sign post for carrying a sign, an intermediate cylindrical hollow bollard post carrying the upper sign post and a lower hollow bollard post mounted immovably in the ground supporting the intermediate cylindrical hollow bollard post. A easily removable pivot base flexible joint member with a dome portion is mounted between the intermediate cylindrical hollow bollard post and the lower hollow bollard post. A quick change-out spring kit is housed substantially with the lower hollow bollard post in includes a coil spring that is compressed by a tension means such as a cable or chain. When the sign post is impacted by a vehicle and the spring kit is damaged a replacement quick change-out spring kit may be easily installed after removal of the original spring kit without the necessity of removing the lower hollow bollard post from the ground.

Abstract translation: 提供了具有快速切换能力和方法的冲击吸收标志柱。 冲击吸收标志柱包括用于承载标志的上标志柱，承载上标志柱的中间圆柱形空心柱柱和不可移动地安装在支撑中间圆柱形空心柱柱的地面中的下空心柱柱。 具有圆顶部分的容易拆卸的枢转基座柔性接头构件安装在中间圆柱形空心柱柱和下空心柱柱之间。 快速更换弹簧套件基本上容纳有下空心柱柱，包括由诸如电缆或链条的张力装置压缩的螺旋弹簧。 当标志杆受到车辆撞击并且弹簧套件损坏时，拆卸原始弹簧套件后，可以轻松安装更换的快速更换弹簧套件，而无需从底座上拆下下空心柱柱。
