Four orthagonally oriented rigid blades are fixed together along a side of each and taper to a common pointed bottom with a rigid top plate affixed across the top of the blades and a steel tube extends upwardly from the plate to receive and support a post such as a sign post, fence post or the like extending upwardly from the device. The invention is adapted to be driven into the ground to support and anchor posts. The invention also includes a "break away" embodiment incorporating a thick high density rubber retainer atop the rigid plate about the tube which has a flanged bottom beneath the rubber retainer and a rigid centrally apertured plate is bolted onto the top plate to hold the rubber retainer and tube on the top plate. A heavy blow to a post mounted in the tube will tilt the tube to pivot the flange thereof to deform the retainer and allow the tube and flange to flip out of the upper apertured plate as a break away feature without damage to the invention. The invention may be readily reassembled after break away by means of the bolts.

DETAILED DESCRIPTION What is claimed is: 1.
A support anchor and system for a post comprising a rigid blade assembly having four blades disposed orthagonally and tapered inwardly from top to bottom to form a bottom point for insertion in the ground, a rigid ground plate secured across the top of said blade assembly for engaging the surface of ground in which said blade assembly is inserted, a post receiving member having a hollow upright configuration with a flange thereabout disposed upon said ground plate for mounting a post in extension upwardly from said system, a limitedly resilient retainer sheet having a central aperture and disposed about said post receiving member upon said flange and ground plate, and means clamping said retainer to said ground plate about the periphery of said retainer, whereby said post receiving member is mounted upon said ground plate via said resilient member so that said post receiving member and flange thereon is pivotally separable from said ground plate by pivotal forces applied to said post receiving member.
2.
The system of claim 1 further defined by said ground plate being comprised of two tabs with each extending between two separate blades.
3.
The system of claim 1 further defined by said ground plate and blade assembly being comprised of two like units with each unit having a pair of tapered blades extending perpendicularly to each other from a common straight edge and tapered to a point at a bottom end of said common edge, and a rigid tab extending across the large top ends of said blades in connection thereto, said two units being fixed together along said common straight edges to dispose said blades in orthagonal array and said tabs in a common plane whereby said ground plate is comprised of said tabs with said blade assembly depending therefrom.
4.
The system of claim 1 further defined by said means clamping said retainer including a rigid apertured plate disposed upon said retainer about said post receiving member and flange with the aperture therein being larger than said flange, and releasable clamping means joining said apertured plate to said ground plate and holding said retainer sheet therebetween, whereby said post receiving member is mounted on said ground plate for pivoting therefrom upon application of sufficient force to resiliently deform said retainer sheet
