Postall easy install posts and fences
A post and fencing system to avoid pre-digging large holes and the use of concrete, using round cross section based posts, tapering from a small diameter section above the lowest end, which is cutter shaped, to where the post extends above the ground, and having screw threads covering the tapered section and increasing in overall diameter and thread thickness from the bottom upward, to give the receiving material around the Postall post maximum compaction and grip in the receiving material and thus give the post greatest resistance to movement, and with such posts having above-ground segments with various cross sections, such as round, square, hexagonal and the like, depending upon the needs of utility and decor, upon which can be attached appropriate fittings to hold in place fence rails, slats, wire, poles and other common fencing materials.

FIELD OF THE INVENTIONThis invention relates to posts to be easily installed into various receiving materials such as dirt, sand, clay, loam and muddy bottoms of bodies of water.
BACKGROUND OF THE INVENTIONCurrently a number of types of posts are installed in earth, sand and other receiving materials, usually by first digging a large hole, setting in and bracing the post and pouring cement or concrete around the post. Once the cement or concrete has set, the bracing is removed, all of which is time consuming. Cement and concrete often leach into surrounding soil and affect plant life.
OBJECTS OF THE INVENTIONIt is a main object of this invention to provide an easy to install post and fencing system using materials that minimally affect plant life.
It is another object of this invention to provide a post and fencing system which can be installed without pre-digging large holes or the use of cement or concrete.
It is an added object of this invention to provide one or more types of plain or ornate fencing systems which can be quickly installed using simple hand tools and or powered equipment.
It is yet an additional object of this invention to provide a post installation that breaks up a minimum amount of receiving material and increasingly compacts the receiving material as posts are installed, to finish with posts resting in hard, firmly packed receiving material.
It is yet another object of this invention to provide a post installation that finishes in solidly compacted receiving material which has been subjected to a minimum of disturbance.
It is even an added object of this invention to provide a finished post installation with maximum contact, especially at or near ground level, between a post and a receiving material.
OPERATING PRINCIPALSPostall system parts are molded, machined and or cast of plastic, metal, composite materials and or wood and the system is initiated by having a cutter shaped end as the lowest section of a post, to cut away receiving material as the post is rotated. Postall posts have screw threads beginning at the diameter of the top of the cutter shaped lowest end and increasing in diameter and thickness as the threads rise up the tapered lower hull portion to ground level, with a straight, tapered or shaped above-ground portion of round, square, fluted or otherwise decorated cross section. The post is rotated manually or by machine using simple tools, whereby the post cuts and screws itself into a receiving material such as dirt, sand, gravel and mud. With an increasing diameter lower hull portion, increasing diameter and thickening screw threads on the lower hull portion, immediately above the cutter shaped lowest end section, increasingly compacting the receiving material and securing a tight fit, a greatly increased resistance to movement by a finished post is achieved in a well compacted receiving material. It is important to note that evenly spaced, increasing in diameter and thickening screw threads follow along the same track made by the initial thread through the receiving material without breaking up that material, but further compacting it.
PREFERRED EMBODIMENTThe preferred embodiment of the Postall invention is a round post having screw threads extending around its tapered lower hull section, from a small diameter, just above its lowest section, which is cutter shaped, upward and outward to where the post will extend above the ground, with the outside diameter of the threads and the thread thickness also increasing from the lower cutter shaped section to where the above ground section of the post begins, to cause maximum compaction of the receiving material around the post for maximum grip of the post, to give the post greatest resistance to movement. Many above-ground cross sections, such as round, square, fluted and hexagonal are used, depending upon the needs of utility and appearance. A number of fittings are also devised, which when attached to the above ground portion of the posts, provide attachment for wire and or various types of cross rails, vertical panels and fencing slats.
DESCRIPTION OF FIGURESClaims
1. A post having its lower hull tapering upward and outward from a bottom point to where the post will be at or near ground level and having threads around the length of its lower hull section and having an above-ground unthreaded section.
2. A post as in claim 1, having a cutter shaped section at its lowest end.
3. A post as in claim 1, having threads which increase in overall diameter from the lowest to highest point on its tapered lower hull section.
4. A post as in claim 1, having threads increasing in thickness as the overall diameter of the threads increase.
5. A post to rail attachment comprised of a plate having a hollow incomplete spherical shaped segment into which is fitted a sphere having a protrusion onto which a rail is attached.
6. A post to rail attachment comprised of a plate having one or more looped arches into which one or more bosses are fitted onto which a rail is attached.
