Post anchor and method of installing a post
First Claim
1. A post anchor to provide for securing a post vertically oriented in earthen ground, the post having an outer surface and extending above grade following installation, the post anchor comprising:
- a) a driveable member adaptable for impact driven insertion into the earthen ground during installation, the driveable member comprising;
1) a post engaging channel to receive the post, the post engaging channel having a first end, a second end situated opposite from the first end, an outer surface and an open passage connecting the first end and the second end, the open passage having an inner surface, the open passage to receive the post;
2) a plurality of ground engaging fins, each ground engaging fin contacting the outer surface of the post engaging channel and having a vertical orientation during and following installation of the driveable member, each ground engaging fin to provide for resistance to horizontal displacement through the earthen ground following installation, each ground engaging fin having an upper edge;
3) a sub-grade surface extending outward generally perpendicularly from the post engaging channel, the post engaging channel extending through the sub-grade surface with the first end of the post engaging channel partially extending above the sub-grade surface, the upper edge of each ground engaging fin at least partially secured to the sub-grade surface, the sub-grade surface wherein to provide for compaction of the earthen ground during installation and resistance to displacement of the earthen ground following installation;
b) locking means to provide for securing the post situated within the post engaging channel to the driveable member;
whereby the driveable member provides for impact driven insertion into the earthen ground where the post may be secured within the post engaging channel using the locking means to prevent vertical motion of the post relative to the driveable member while the ground engaging fins and the sub-grade surface cooperate to provide resistance to motion of the post following installation;
c) a compression slot situated in said post engaging channel proximate the first end and extending longitudinally a predetermined distance along the length of said post engaging channel toward the second end, wherein the locking means provides for a compression of said post engaging channel proximate said compression slot to bring a portion of the inner surface of said post engaging channel into contact with a portion of the outer surface of the post.

Abstract
A post anchor adaptable to impact insertion into the earthen ground to rigidly support a post extending above ground level. The post anchor is functional without requiring the use of concrete to reinforce the post anchor within the earthen ground. A driveable member and a locking member cooperate to form each post anchor. A post engaging channel cooperates with a plurality of ground engaging fins and a sub-grade surface to provide displacement resistance properties to the post anchor. The resistance properties include the sub-grade surface compacting the earthen ground during and following installation and restricting displacement of earthen ground over the ground engaging fins following installation. A secure attachment, using the locking member, occurs to secure the post to the driveable member following placement of both the post and the driveable member during the installation procedure. The driveable member may be of a one piece construction, as would result from a molding process, or construction of the driveable member may be from a sheet material. When construction of the driveable member is of a sheet material, the sheet material is subjected to a deforming process to render definable unique panels thereon definable from adjacent panels by a linear juncture. Either a single sheet piece or multiple sheet pieces form the driveable member. An installation aid permits easy insertion of the driveable member into the earthen ground. The post anchor permits repositioning of the post relative to the driveable member following installation.

6. A method of installing a post into earthen ground to a final driven depth, the earthen ground having a grade, the method comprising the steps of:
-
a) providing a post anchor comprising; 1) a driveable member comprising; a) the post engaging channel to provide for slidably receiving the post; b) a plurality of ground engaging fins, each ground engaging fin disposed about the post engaging channel and having a vertical orientation during and following installation of the driveable member, each ground engaging fin to provide for resistance to displacement of the driveable member through the earthen ground following installation; c) a sub-grade surface having a horizontal orientation during and following installation of the driveable member, the post engaging channel extending through the sub-grade surface, each ground engaging fin securely connected to the sub-grade surface, the sub-grade surface to provide for resistance to displacement of the driveable member through the earthen ground following installation; 2) a locking member to provide for locking a post within said post engaging channel of the driveable member at a desired elevational position relative to the driveable member; b) then, locating a desired position of placement of the post; c) then, excavating a hole at the desired position of placement having a diametric measurement greater than the diametric measurement of the sub-grade surface of the driveable member, the excavated hole having a base, the base having an excavated grade; d) then, positioning the post and the driveable member into the excavated hole with the post driven to a depth not exceeding the final driven depth; e) then, driving the driveable member to place the sub-grade surface below the grade of the earthen ground to bring the sub-grade surface into contact with the excavated grade within the excavated hole while the post acts as a guide for the driveable member; f) then, driving the post to the final driven depth; g) then, positioning the locking member to secure the post to the driveable member; h) then, filling the excavated hole with soil to cover the driveable member and the locking member; whereby the position of placement of the post is located, then excavation of a shallow hole occurs at this location, then the post and the driveable member are positioned into the excavated hole with the post driven to a depth not exceeding the desired final driven depth, then the driveable member is driven into the earthen ground to place the sub-grade surface into contact with the excavated grade while the post acts as a guide, then the post is driven to the final driven depth, then the locking member is positioned to secure the post to the driveable member and then the excavated hole is filled to cover the driveable member and the locking member. - View Dependent Claims (7, 8, 9)
