Abstract
Abstract A pole structure such as for signs or utility installations is composed of a plurality of tubular tapered sections locked one to each other in telescoping fashion; the lowest section of the pole structure has a flange which is releasably attached to an inground base support of the pole by means of pivot clamps and/or shear pins which are adapted to give way or break when the pole is hit by an object at a certain magnitude of impact force to thereby permit the pole to break-away from the base without destroying the pole; the several individual taper lock pole sections, when the pole breaks-away from the base, are permitted to separate, permitting substantially complete recovery of the pole structure after being forcibly yanked from its ground support by the impact force.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
225 words
A pole and associated support base assembly comprising: a base member set within the ground having a portion extending above the ground surface; said above ground portion comprising a plate member; a fabricated pole assembly, the pole assembly being provided with a radial flange at the lower end thereof; said radial flange being adapted to be supported in flat abutting relationship on top of said plate member; and releasable means normally rigidly securing said radial flange to said plate member to maintain said fabricated pole in vertical upright position on said base support; there being a series of spaced vertically aligned outwardly opening radial indentations in said plate member and radial flange; said means releasably securing said radial flange to said plate member comprising a plurality of split clamp assemblies circumferentially spaced therearound; each clamp assembly including superimposed upper and lower clamp members located within said indentations, with their free respective ends overlapping and retainingly engaging the corresponding adjacent top and bottom surfaces of said radial flange and plate member; a fastener extending through each pair of clamp members for securing said clamp members to each other and said flange and plate member; said clamp assemblies when subjected to an impact force of a certain magnitude being adapted to slide from the plate member permitting the pole assembly to swivel off the base support plate.
Claim 2
Dependent Claim
225 words
A pole and associated support base assembly comprising: a base member set within the ground having a portion extending above the ground surface; said above ground portion comprising a plate member; a fabricated pole assembly, the pole assembly being provided with a radial flange at the lower end thereof; said radial flange being adapted to be supported in flat abutting relationship on top of said plate member; and releasable means normally rigidly securing said radial flange to said plate member to maintain said fabricated pole in vertical upright position on said base support; there being a series of spaced vertically aligned outwardly opening radial indentations in said plate member and radial flange; said means releasably securing said radial flange to said plate member comprising a plurality of split clamp assemblies circumferentially spaced therearound; each clamp assembly including superimposed upper and lower clamp members located within said indentations, with their free respective ends overlapping and retainingly engaging the corresponding adjacent top and bottom surfaces of said radial flange and plate member; a fastener extending through each pair of clamp members for securing said clamp members to each other and said flange and plate member; said clamp assemblies when subjected to an impact force of a certain magnitude being adapted to slide from the plate member permitting the pole assembly to swivel off the base support plate.
Claim 3
Dependent Claim
225 words
A pole and associated support base assembly comprising: a base member set within the ground having a portion extending above the ground surface; said above ground portion comprising a plate member; a fabricated pole assembly, the pole assembly being provided with a radial flange at the lower end thereof; said radial flange being adapted to be supported in flat abutting relationship on top of said plate member; and releasable means normally rigidly securing said radial flange to said plate member to maintain said fabricated pole in vertical upright position on said base support; there being a series of spaced vertically aligned outwardly opening radial indentations in said plate member and radial flange; said means releasably securing said radial flange to said plate member comprising a plurality of split clamp assemblies circumferentially spaced therearound; each clamp assembly including superimposed upper and lower clamp members located within said indentations, with their free respective ends overlapping and retainingly engaging the corresponding adjacent top and bottom surfaces of said radial flange and plate member; a fastener extending through each pair of clamp members for securing said clamp members to each other and said flange and plate member; said clamp assemblies when subjected to an impact force of a certain magnitude being adapted to slide from the plate member permitting the pole assembly to swivel off the base support plate.
Claim 4
Dependent Claim
225 words
A pole and associated support base assembly comprising: a base member set within the ground having a portion extending above the ground surface; said above ground portion comprising a plate member; a fabricated pole assembly, the pole assembly being provided with a radial flange at the lower end thereof; said radial flange being adapted to be supported in flat abutting relationship on top of said plate member; and releasable means normally rigidly securing said radial flange to said plate member to maintain said fabricated pole in vertical upright position on said base support; there being a series of spaced vertically aligned outwardly opening radial indentations in said plate member and radial flange; said means releasably securing said radial flange to said plate member comprising a plurality of split clamp assemblies circumferentially spaced therearound; each clamp assembly including superimposed upper and lower clamp members located within said indentations, with their free respective ends overlapping and retainingly engaging the corresponding adjacent top and bottom surfaces of said radial flange and plate member; a fastener extending through each pair of clamp members for securing said clamp members to each other and said flange and plate member; said clamp assemblies when subjected to an impact force of a certain magnitude being adapted to slide from the plate member permitting the pole assembly to swivel off the base support plate.
Claim 5
Dependent Claim
79 words
In the pole and support assembly of claim 1, said pole assembly composed of a plurality of individual tubular sections; each of said tubular sections being tapered in an upwardly converging relationship with the next tubular section for assembly of said plurality of said tubular sections in telescoping fashion one on top of each other; said plurality of tapered tubular sections being retained in assembled vertical position by means of a frictional interlock between said telescopically assembled tapered sections.
Claim 6
Dependent Claim
20 words
In the pole and support assembly of claim 1, said upper and lower clamp assemblies being of substantial triangular configuration.
