发明名称 Post support and anchor
摘要 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.
