IN-GROUND POLE RECEPTACLE
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.
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 INVENTIONThis invention relates, generally, to flagpole holders. More particularly, it relates to pole and flagpole receptacles which are embedded in the ground.
BACKGROUND OF THE INVENTIONIt 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 INVENTIONThe 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.
The invention will now be described with reference to the attached drawing figures. It should be understood that the drawings are intended to be merely illustrative of the invention, and may not be drawn to scale.

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.
Claims
1. An outdoor in-ground pole receptacle comprising:
- a top plate component having a central aperture;
- a stake component having a cylindrical chamber closed at a lower end and provided with an outward-facing annular flange at an open upper end thereof, said stake component sized to fit through said central aperture so that said annular flange rests on an upper surface of said top plate; and
- a cover which fits over said open upper end of said stake component to prevent dirt and debris from entering said cylindrical chamber.
2. The outdoor pole receptacle of claim 1, which further comprises:
