Abstract
Abstract A pole base for securing a pole to a surface area consisting of a two-piece housing having a pole-receiving cylindrical opening and a cavity communicative to one side wall of the cylinder. Within the cavity is disposed a wedge having an inclined surface so that the wedge moves into the cylindrical surface of the housing. The wedge includes pole engaging surfaces and a screw bolt threadably engaged to the top of the wedge so that the wedge can be moved upward against a corresponding inclined wall of the cavity and secure itself to a pole inserted into the cylindrical hole of the pole base.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
155 words
A pole base for securing a pole to a surface area comprising: a two-piece housing having a pole receiving opening defining a cylindrical hole, and a cavity positioned adjacent to the opening and communicative to one side wall of the cylinder, said cavity having an inclined wall sloping toward the opening, said housing having an aperture adjacent to said cylindrical hole and communicative with said cavity; a wedge having an inclined surface for sliding contact with the inclined wall of the cavity and disposed within said cavity, said wedge having a pole engaging surface communicative with said cylindrical surface and having a threaded bore in one surface; and a screw bolt disposed through the aperture in said housing and engaging said threaded bore for moving said wedge within said cavity so that the movement of said wedge toward the opening of the pole base against said inclined wall forces said wedge into the cylindrical area.
Claim 2
Dependent Claim
155 words
A pole base for securing a pole to a surface area comprising: a two-piece housing having a pole receiving opening defining a cylindrical hole, and a cavity positioned adjacent to the opening and communicative to one side wall of the cylinder, said cavity having an inclined wall sloping toward the opening, said housing having an aperture adjacent to said cylindrical hole and communicative with said cavity; a wedge having an inclined surface for sliding contact with the inclined wall of the cavity and disposed within said cavity, said wedge having a pole engaging surface communicative with said cylindrical surface and having a threaded bore in one surface; and a screw bolt disposed through the aperture in said housing and engaging said threaded bore for moving said wedge within said cavity so that the movement of said wedge toward the opening of the pole base against said inclined wall forces said wedge into the cylindrical area.
Claim 3
Dependent Claim
36 words
The pole base as recited in claim 1 wherein each piece of said two-piece housing includes flanges having corresponding apertures, and a rivet inserted through the aperture of each flange for securing the two pieces together.
Claim 4
Dependent Claim
35 words
The pole base as recited in claim 1 wherein at least one piece of said two-piece housing includes an edge rib formed around the rim of the mating edge to align the other housing piece.
Claim 5
Dependent Claim
39 words
The pole base as recited in claim 1 wherein said housing additionally includes a base shelf formed at one end of the cylindrical hole, said base shelf including a drain aperture having a smaller diameter than said cylindrical hole.
Claim 6
Dependent Claim
27 words
The pole base as recited in claim 1 wherein the pole engaging surface of said wedge includes jaws formed longitudinal to the axis of said cylindrical hole.
