Post anchor

摘要

A post anchor for securing a support post for a structure comprises a base with four upstanding sidewalls forming a cavity into which a post is inserted, and means to secure the post inside the cavity. Interior ribs and exterior augmented corners resist deformation under pressure exerted by the post. Interior channels allow water to drain from inside the cavity toward a drain hole. The anchor post is slightly elevated relative to the ground, allowing air and water to circulate around the post and post anchor. The post anchor is made of a thermoplastic polymer which is given a textured surface, and may include an ultraviolet protection additive.

主权项

1. A post anchor comprising:
a base having an upper surface and an underside; a plurality of upstanding sidewalls supported on said upper surface of said base; each of said sidewalls abutting two other of said sidewalls to form two corners; the sidewalls extending substantially straight upwardly from the upper surface of the base to define, together with the upper surface of the base, an upwardly opening concavity, a perimeter of an opening of the upwardly opening concavity defined by uppermost edges of the concavity-defining interior surfaces of the substantially straight upwardly extending sidewalls; and wherein said sidewalls have an increased thickness about each of said corners, wherein the increased thickness about each of the corners comprises a lower region of increased thickness proximate the base and an upper region of increased thickness proximate the uppermost edges of the sidewalls and wherein the lower region extends further from the corner and along the abutting sidewalls that form the corner than the upper region wherein said increased thickness is exterior to said upwardly opening cavity; and further comprising a plurality of first apertures defining first passageways through at least one of said side walls into said upwardly opening concavity, said first passageways configured to receive fasteners for securing said post anchor to a support post inserted into said upwardly opening concavity; a plurality of second apertures defining second passageways from said underside of said base into said upwardly opening concavity, said second passageways configured to receive fasteners for securing said base to said support post; and a plurality of third apertures defining third passageways outside said upwardly opening concavity from said upper surface of said base through said underside of said base, said third passageways configured to receive fasteners for securing said base to a flat surface; wherein each of said sidewalls comprises one or more interior ribs, wherein, for each of the sidewalls, the one or more interior ribs extend from a concavity-defining interior surface of the sidewall into the concavity, and said ribs comprising front surfaces spaced further apart from the cavity-defining interior surface of said sidewall than any other part of said ribs and extending upwardly from the base in a direction perpendicular to the base.
