Abstract

An in-ground pole receptacle can be driven into or buried in the ground by a homeowner or other individual who is familiar with the routing of underground sprinkler pipes. The pole receptacle has a stake component with a cylindrical chamber that serves as a receptacle for the lower end of a flagpole or other pole and a top plate component that prevents grass from growing around the opening of the cylindrical chamber. The holder is further equipped with a hinged cap or resilient plug secured to the top plate component that is used to cover the opening of the chamber so that soil and debris can be excluded from the chamber when the pole is not installed therein. The stake component and the top plate component can be formed separately or they can be unitary.

Description

This application has a priority date based on the filing of Provisional Patent Application No. 61/531,578, titled IN-GROUND FLAGPOLE HOLDER, by the same inventor, on Sep. 6, 2011.

FIELD OF THE INVENTION

This invention relates, generally, to flagpole holders. More particularly, it relates to pole and flagpole receptacles which are embedded in the ground.

BACKGROUND OF THE INVENTION

It is a common practice for Boy Scout troops and other civic organizations to rent U.S. flags, for use on national holidays, to subscribers in a community, for a annual fee. Typically, the flagpole is driven into the ground in front of the subscriber's home. Unfortunately, the flag installers normally have no map of the sprinkler system pipes below the surface. Consequently, it is not unusual for the flag installer to break or sever one of these sprinkler system pipes, resulting in a huge leak and at least one unusable sprinkler system circuit. There is a need for not only an in-ground flagpole receptacle, but also in-ground receptacles for poles of other types. Volleyball nets are frequently set up temporarily for parties. With receptacles for volley ball net poles already properly positioned in the ground, the need to drive poles into the ground and brace them with ropes and stakes will be eiliminated.

SUMMARY OF THE INVENTION

The present invention provides an new in-ground holder, for flagpoles and other temporary poles, that can be driven into or embedded in the ground by the homeowner or other individual who is familiar with the routing of underground sprinkler pipes. Several embodiments of the pole and flagpole holder are shown and described.
A first main embodiment flagpole holder has a stake component with a cylindrical chamber that serves as a receptacle for the lower end of a flagpole. In addition, the stake component has an annular flange at an upper opening of the chamber and a generally conical portion at the bottom end of the chamber. The annular flange is preferably made by flaring an upper edge of the pipe or tube in a stamping and flaring operation. The conical portion is preferably made by crimping three evenly-radially-spaced double-thickness fins around the lower portion of section of mild steel tubing as the conical portion is formed around a conical die positioned within the interior of the tubing. A top plate component has a central aperture that is sized to slide over the conical portion and up a cylindrical portion of the stake component until it abuts the annular flange. The top plate component can either remain unsecured to the stake component, or it can be secured to the stake component by welding or by bonding with an adhesive agent, such as epoxy. For stake components that are to be embedded in concrete, the conical portion can be dispensed with and replaced with a laminar circular slug that is welded to the bottom of the pipe or tube. The in-ground pole and flagpole holder is further equipped with a resilient plug that is used to plug the upper entrance to the chamber of the stake component so that soil and debris can be excluded from the chamber when the flagpole is not installed therein. The resilient plug can be attached to the top plate component with a chain, cord, or cable.
For a second main embodiment of the in-ground pole and flagpole holder, the top plate component is modified so as to eliminate the need for the resilient plug. Instead, top plate component is equipped with a hinged, normally-closed, spring-loaded cap, which seals the ground-level opening of the stake component. A resilient sealing pad, which is adhered to the lower surface of the spring-loaded cap, prevents soil and other debris from entering the cylindrical chamber when the cap is closed over the opening.
For any of the three embodiments of the invention, the top plate component may be made in various shapes, thickness and sizes. The stake component need not be cylindrical, by may also be of square cross section.

Hinge support 1002A has a hinge pin aperture 1003A and hinge support 1002B has a hinge pivot aperture 1003B. The central aperture 1001 is sized to that the top plate component 1000 can slide over the lower pointed end of the first embodiment stake component 100 or the blunt lower end of the second embodiment stake component 200 until it contacts the upper flange 102 or 202, respectively. The top plate component 1000 can be welded to the stake component 100 or 200 at the factory, or it can be shipped apart from the stake component. Preferably, the second embodiment top plate component 1000 is packaged unassembled from the stake component 100 or 200 so as to enable more efficient packaging of the in-ground pole receptacle. The first embodiment top plate component 1000 will, then, be installed on the stake component 100 by a purchaser, who may decide to bond the first embodiment top plate component 1000 to the stake component 100 or 200 using an material such as epoxy or powdered-steel-filled epoxy. If the purchaser does not want to both with adhesive bonding of the top plate component 100 to the stake component 100 or 200, the first embodiment top plate component 700 may be left free to rotate about the stake component 100 or 200. One of the functions of the second embodiment top plate component 1000 is to prevent the growth of grass or other vegetation around the opening of the cylindrical chamber 103 or 203 so that the in-ground pole receptacle can be more easily located after it has been installed in the ground.
Referring now to FIG. 11, a hinged cap 1100, used in combination with the second embodiment top plate component, is preferably stamped and formed from mild steel sheet metal. After stamping and forming, it is preferably galvanized to protect it against corrosion. The cap 1100 has a circular cover portion 1101 and a rear hinge portion 1102.

The hinge pin 1200 is then slid through hinge pin apertures 1003A and 1104A, the spring 1401 is installed on the hinge pin 1200, and then, with the spring configured as shown in the drawing, the hinge pin is slid through the remaining hinge pin apertures 1003B and 1004B. The hinge pin installation operation could, of course, be performed in the opposite direction. The ends of the hinge pin can then be epoxied to the hinge supports 1002A and 1002B. Alternatively, a hitch pin or a clevis pin of the appropriate diameter and length may replace the plain hinge pin 1200.
Although only several embodiments of the in-ground flagpole holder have been heretofore shown and described, it will be obvious to those having ordinary skill in the art that changes and modifications may be made thereto without departing from the scope and the spirit of the invention as hereinafter claimed. For example, the central aperture of either embodiment top plate component may be internally threaded and the upper end of either embodiment stake component may be externally threaded so that the two components can threadably engage one another. Alternatively, a more elaborate twist and lock mechanism may be used to couple the stake component to the top plate component. It should be understood that the depicted embodiments are intended to minimize manufacturing costs, thereby making the product affordable to a great many consumers. Although all embodiments of the invention employ a generally cylindrical stake component, a stake component having a square cross section, or even a triangular cross section may also be used if the top plate component is also similarly modified. It is also possible to make both the top plate component and the stake component as a unitary piece through either injection molding using a structural polymer material such as ABS or through casting using a metal such as iron or brass.
