发明名称 Drivable post and marker
摘要 An anchor system for flexible marker posts comprises an anchor that receives a post before the anchor is driven into the ground. In a first embodiment, a flat, rectangular plate of mild steel is folded into a U-shape with parallel upper and lower plates. The lower end of a post is placed within the anchor, and the anchor is driven into the earth with a bladed driver, the anchor bending into a V-shape along an axis defined by the blade of the driver. The anchor retains the post with friction, and 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.
