Post anchor with drive pin and ground displacement wedge
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.
