Abstract
An anchor system for flexible marker posts comprises an anchor that receives a post before the anchor is driven into the ground. In one version of the anchor system, a V-shaped configuration folded along two longitudinal side axes and one lower lateral axis. This version has front and rear plates, and the rear plate has and combines with two flanges to define a narrow pocket that receives the post. The post is secured in the pocket by deforming the pocket with punches. The anchor is retained in the earth by mechanical interference and friction. Additional embodiments include plates that are pre-bent into a V-shape, tabs for maintaining separation of the plates, and a one-piece anchor having a V-shaped lower portion and coplanar, horizontal, upper surfaces connected to the upper edges of the lower portion.
