FIELD OF THE INVENTION This invention relates to fence hardware for easily attaching fence rails to posts which are installed on a level or variable elevation or angular receiving materials.
BACKGROUND OF THE INVENTION Currently 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. Fencing is then nailed or otherwise attached to the posts.
OBJECTS OF THE INVENTION It 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.
It is an object of this invention to provide hardware with which to attach fencing to posts.
OPERATING PRINCIPALS Postall 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. Once the posts are in place the Fence EZ hardware is attached to the posts and cross rails and fence elements are attached to various parts of the hardware and a completed fence is achieved.
PREFERRED EMBODIMENT The 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, often depending upon the preferred appearance. A variety of Fence EZ hardware fittings can then be attached to the posts to create differing fence appearances and to compensate for uneven ground elevations. Cross rails, vertical panels and fencing panels or slats are then attached to the Fence EZ hardware.
DESCRIPTION OF FIGURES FIG. 1 is a perspective view of a Postall installation showing round lower section posts screwed into a receiving material, with ground level, 105, being the transition point from a round, tapered in-ground hull, with threads, to a square cross section above ground post, 100, having attachment means, 101, whereby rectangular section cross rails, 103, are attached to posts, to which are attached fence slats, 106, and with decorative square section post caps, 102, installed.
FIG. 2 is a perspective view of a typical Postall fencing installation where a round lower section with screw threads, 110, is screwed down between and not damaging tree roots, 112, and with cross rails, 108, attached to the above-ground posts, 111, by way of angularly adjustable attachment hardware, 109. Note that one post, 104, is installed into bottom mud, 116, in a pond, 114, and has an upward extension, 115, to provide a horizon-level appearance of the cross rails, with post caps, 107.

Note that two sizes of cross rail, to which other fencing may be attached, can be used with this one part. A small cross rail can be inserted inside, 130, while a larger cross rail can be inserted over the outside, 136.
FIG. 17 is a cross section view of a rail attachment, with a rail support shaft, 129, a round, square or rectangular spacer-adaptor, 138, on the rail support shaft, 129, a spherical housing, 127, and a spherical end, 128, with attachment hardware, 125, fastening the assembly to a post, 126. Note that a wide variety of cross-section shapes can be devised and used for item 138 to meet the cross section shape of a matching fence rail.
FIG. 18 is a perspective view of the parts shown in FIGS. 13 and 16, assembled, with top and bottom bosses, 135, a rail attachment plate, 134, and a typical rectangular cross section rail, 144, placed over a rail insert member, 136.
FIG. 19 is a perspective view of a Fence EZ rail attachment assembly showing a round post attachment plate, 142, with a spherical housing, 127, a spherical end, 128, and a round spacer-adaptor, 138, over a rail support shaft, 129, and a round cross section rail, 143, made to internal and external diameters of common metal and or plastic pipe. Note that a smaller fence rail, the inside dimension of which is slightly larger than the outside dimension of the support rail shaft, 129, shown in FIGS. 12 and 17, can be fitted directly over the support rail shaft, 129.
FIG. 20 is a view of the lower end of a Postall post showing a screw thread, 146, ending just above a cutter shaped end section with side cutting edges, 147, and bottom cutting edge, 145.
FIG. 21 is a view of a four bar tool having four wooden handles, 153, held together with common wood screws, 154, forming a square the size of a square cross section Postall post for installing typical square cross-section Postall posts.
FIG. 22 is a view looking up towards the bottom of a cutter shaped end section of a typical Postall post, showing two side cutting edges, 147, and one bottom cutting edge, 145.
FIG. 23 is a view of a single handle, 148, and belt, 151, tool, assembled with hardware, 149, made to fit around a typical Postall post, 152, shown here as round. Note that this device can be used to install a number of sizes and cross section shapes of Postall posts, as it grips more tightly when the belt, 151, is wrapped around a post and the handle is used to rotate the post clockwise in this view.
FIG. 24 is a perspective view of a mechanism added to a typical back-hoe tractor type vehicle, whereby a hydraulic motor, 162, rotates a socket wrench, 163, placed over a square section post, not shown, which is held loosely by holding adaptors, 165, fitted onto a set of tines, 164, on a common barrel-drum rotator. Note that the socket wrench, 163, can be replaced by a handle and belt device, such as that shown in FIG. 23, for power installation of most Postall posts.
FIG. 25 is a view of a manual installation of a Postall post, 157, where a man is shown using two handle and belt devices, 158, such as shown in FIG. 23, to rotate and screw a post into a receiving material, 159, by having a cutter shaped end section, 161, cut into and break up the receiving material allowing screw threads, 156, to follow.
FIG. 26 is a view of a back-hoe tractor vehicle, 166, using the attachment mechanism shown in FIG. 24, with a hydraulic motor, 162, a socket wrench, 163, ground level, 168, a threaded section on the tapered hull, 169, of a post, and a lower cutter shaped end section, 161. Such small, simple powered equipment is used to rapidly install Postall posts.
