Post anchor with drive pin and ground displacement wedge

Abstract

A post anchor includes a ground engaging portion in the form of fins and a post receiving portion in the form of a tubular member. A side wall of the post receiving portion has a bottom portion that is inwardly tapered and fastened between and to adjacent ones of the fins at an angle to form a ground displacement wedge that also structurally reinforces the fins. A drive pin is attached to at least one of the fins in a position where a top of the drive pin is generally flush with a top edge of the fin to which the drive pin is attached.

1 . A post anchor, comprising:
 a ground engaging portion comprising at least one fin;   a post receiving portion mounted to the ground engaging portion and sized and shaped to receive a post; and   a drive pin attached to the fin and positioned in alignment with a top edge of the fin.   
   
   
       2 . The post anchor of  claim 1  wherein the drive pin is a solid round bar mounted to the fin. 
   
   
       3 . The post anchor of  claim 1  wherein the drive pin is a hollow round tube mounted to the fin. 
   
   
       4 . The post anchor of  claim 1  wherein the drive pin is a plate extending between two adjacent fins across a corner between the adjacent fins. 
   
   
       5 . The post anchor of  claim 1  wherein the post receiving portion further includes at least one aperture in a surface thereof for receiving mounting hardware to secure the post in position within the post receiving portion. 
   
   
       6 . The post anchor of  claim 1  wherein the post receiving portion further includes at least one aperture in a surface thereof through which an adhesive is injected to secure the post in position within the post receiving portion. 
   
   
       7 . The post anchor of  claim 1  wherein the drive pin is mounted to two adjacent fins at a corner between those adjacent fins. 
   
   
       8 . The post anchor of  claim 1  wherein the post receiving portion includes a wall, wherein a bottom portion of the wall is inwardly tapered and fastened between and to adjacent ones of the fins at an angle to form a ground displacement wedge. 
   
   
       9 . A post anchor, comprising:
 a ground engaging portion comprising at least one fin; and   a post receiving portion mounted to the ground engaging portion and sized and shaped to receive a post, the post receiving portion including a side wall, a bottom portion of the side wall being inwardly tapered and fastened to the fin at an angle to form a ground displacement wedge.   
   
   
       10 . The post anchor of  claim 9  further comprising a drive pin attached to the fin. 
   
   
       11 . The post anchor of  claim 9  wherein a top of the drive pin is positioned in alignment with a top edge of the fins. 
   
   
       12 . The post anchor of  claim 10  wherein the drive pin is a solid round bar mounted to the fin. 
   
   
       13 . The post anchor of  claim 10  wherein the drive pin is a hollow round tube mounted to the fin. 
   
   
       14 . The post anchor of  claim 10  wherein the drive pin is a plate extending between two adjacent fins across a corner formed by those two adjacent fins. 
   
   
       15 . A post anchor, comprising:
 a ground engaging portion comprising a fin;   a post receiving portion comprising a tubular member having a wall with a bottom portion being inwardly tapered and fastened to the fin at an angle to form a ground displacement wedge; and   a drive pin attached to the fin in a position where a top of the drive pin is generally flush with a top edge of the fin to which the drive pin is attached.   
   
   
       16 . The post anchor of  claim 15  further comprising another fin wherein the drive pin is mounted in a corner formed between two adjacent fins. 
   
   
       17 . The post anchor of  claim 15  wherein the tubular member has a square cross-sectional shape. 
   
   
       18 . The post anchor of  claim 15  wherein the drive pin is a solid round bar mounted to the fin. 
   
   
       19 . The post anchor of  claim 15  wherein the drive pin is a hollow round tube mounted to the fin. 
   
   
       20 . The post anchor of  claim 15  further comprising another fin wherein the drive pin is a plate extending between two adjacent fins across a corner formed between the fins.
