ABSTRACT:
My assembly for mounting a sign post or the like on a stationary base or footing includes, in a presently preferred embodiment, a platform attached to the post near the bottom thereof and connected to the stationary base by breakaway coupling members spaced radially from the vertical axis of the post. The platform secured to the post has load concentrating elements associated therewith and located thereon, such as being formed integral therewith, and operable to equalize the load applied to the coupling members upon application of a wind load or the like to the sign at a point on the post remote from the platform whereas the coupling members will be readily broken upon impact of a vehicle with the lower portion of the post.
