Abstract
An elongated vertical plastic ground mount post for mailboxes is provided having an upper portion suitable for supporting a mailbox, as by insertion into a hollow support column of a plastic mailbox, and a lower portion with vertically spaced notches which serve to retain the post in place in the ground when earth is compacted against the lower portion.
Description
BACKGROUND OF THE INVENTION

Rural mailboxes are usually mounted on vertical wooden posts, which are subjected to deterioration through decay or termite attack. Also, the typical square or round wooden mailbox post can be loosened and lifted out of the ground by pranksters—much to the irritation and inconvenience of the mailbox owner and mail delivery personnel.


BRIEF SUMMARY OF THE INVENTION

An elongated plastic ground mount post is provided for supporting a mailbox. The post has a substantially square cross section and a lower portion with scalloped corners forming notches, which are filled with earth or gravel when installed. By tamping the soil and/or gravel of the earth around the post upon installation, the packed earth in the area of the notches affords considerable resistance to any attempt to remove the post. By forming the post of a suitable strong plastic, deterioration of the post is avoided and a strong installation is provided which resists accidental or vandal like destruction.

DETAILED DESCRIPTION OF THE INVENTION

Referring to FIG. 1, an elongated vertical ground mount post 11 is illustrated supporting a plastic mailbox 12. The detailed construction of the ground mount post 11, which is made of polyethylene, is shown in FIGS. 2–6. The elongated plastic post 11 has four exterior sides or side surfaces 16, 17, 18, 19 extending in the direction of its elongation and defining a substantially square or quadrilateral shape. The four corners of the post 11 are beveled or rounded to form rounded corners or rounds 21, 22, 23, 24. The top and bottom of the post 11 also have rounded corners or edges to facilitate insertion into an opening in the hollow column 31 of the plastic mailbox 12 and the hole 37 in the ground 42.


A four corners of the lower portion 36 of the post 11 have a plurality of vertically spaced indentations or notches 41 which form recesses extending slightly more than one third of the way into the sides 16, 17, 18, 19. The notches 41 form pockets for soil or gravel tamped or packed around the post 11 installed in the hole 37 in the ground 42, thus providing resistance to removal of the post 11. The upper portion 51 of the post 11 is releasably secured to the hollow post receiving support column 31 of the plastic mailbox 12 by suitable fasteners such as screws 52.



FIG. 7 is a section through a post 61 of alternate construction which has a hollow interior formed by a round opening 62 extending between its opposite ends. This construction saves material and weight without a substantial sacrifice of strength.


The plastic ground mount post 11 is suitable for mounting a plastic mailbox of the type having a hollow support column such as shown in FIG. 1. It is strong. It is relatively easy is install and provides an exceptionally long life since it does not deteriorate because of rot and it is not subject to attack by termites and the like.

Claims
