Abstract A detachable post anchor for use with highway marker posts and the like is provided. The anchor comprises two separable elements, more particularly a spike member and a holder. The spike member includes a spike, a horizontal base plate carried by the spike at its upper end, and a slotted lug extending upwardly from the base plate. The holder is tubelike in form and receives the bottom end of the post in its upper end. A pair of spaced, vertical, slotted lugs are fixed within the bottom end of the holder. The slots of the spike and holder lugs line up when the holder is mounted on the base plate. A shear pin is inserted through the lugs to secure the holder and spike together. When the post is struck from the side, the holder pivots about its bottom edge; the shear pin parts and the post and holder topple over. The anchor can be re-assembled by insertion of a new shear pin.
In combination: a tubelike holder having an opening in its side wall; said holder being adapted to receive and retain the lower end of a post in the upper end thereof; means traversing said holder inwardly of the lower end thereof; an anchor member having a spike, for insertion in the ground, and a base plate carried by the spike at its upper end, said base plate having an upwardly turned peripheral flange; a pair of spaced, vertical lugs fixed to the traversing means and being disposed within the lower end of the holder, each such lug having a longitudinal slot formed therein; a rigid lug, having a longitudinal slot extending therethrough, said rigid lug extending upwardly from the base plate between the said pair of holder lugs; the lug slots and holder opening being aligned; a shear member extending through the lug slots and releasably connecting together the holder and anchor member; said pair of holder lugs being spaced apart sufficiently whereby the said lugs may be displaced from the operative position without jamming when the holder is pivoted about its bottom edge.
