Abstract
Abstract An elongated tapered enclosure tightly receives a collar attached to the bottom of a post. A plurality of adjustable wedges at the top of the enclosure engage the post and serve to plumb the post and firmly secure it in the enclosure. The enclosure is set in the ground flush with the ground surface. Posts are easily inserted into and removed from the enclosure to provide portable members for supporting traffic signs, walls, partitions, roofs and the like.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
241 words
A system for supporting a post having any one of a plurality of cross-sectional configurations, the system comprising: an elongated enclosure having an upper open end and decreasing internal lateral dimensions along the length thereof from said open end; a post support collar attachable by fasteners to a lower end portion of said post and fully insertable into said enclosure through said open end, said collar being dimensioned to tightly engage the lower interior walls of said enclosure at a position along the length thereof; a plurality of wedges engaging said post at selected locations about the periphery of the post and engaging the internal walls of said enclosure at the open end of said enclosure, said wedges being selectively movable to adjust the position of said post relative to the walls of said enclosure; at least two of said pluality of wedges each including two complementary mating portions movable relative to one another to change the external lateral dimension of the wedge; one of said two complementary mating portions including a threaded longitudinal groove and the other of said complementary mating portions including a longitudinal unthreaded groove, said threaded and unthreaded grooves mating with one another to form a longitudinal bore internally of said wedge; and a threaded rod disposed in said bore, said rod being rotatable to move the complementary mating portions of said wedge relative to one another, thereby to change the external lateral dimension of said wedge.
