ABSTRACT:
A flag assembly includes an elongated and rectilinear shaft having opposed end portions situated adjacent a ground surface. The shaft includes a banner attached to one of the end portions having surface indicia imprinted thereon. A protective cover member is provided with a centrally registered countersunk bore situated therebelow. A frusto-conical spring member having axially opposed first and second end portions is conjoined to another end portion of the shaft and extends downwardly away therefrom along a vertical plane respectively. A bushing having a monolithically formed lower portion provided with a tapered diameter is inwardly offset from a diameter of the shaft. The bushing further has an axially registered upper portion operably conjoined to the spring member and cooperating with the shaft such that the spring member can be resiliently adapted between compressed and equilibrium positions to absorb vertically channeled impact forces encountered during installation procedures.
