Abstract
An environmentally friendly fiberglass utility pole that comes in three sections that are telescoped one around the other to provide a strong, wind and bending resistant structure. Each of the three sections has alternating protruding and intruding surfaces that are slip fit together to provide maximum strength while conserving material. Additionally, each of the three sections preferably are different lengths such that maximum reinforcement is provided along the center of the length of the pole, without requiring excessive material (or weight) at the top end of the pole.
Claims23
A utility pole, comprising:
- an inner pole section having an outer surface with both protruding and intruding regions,
- a hollow center pole section received around the inner pole section, wherein the center pole section has both protruding and intruding regions on both its inner and outer surfaces;
- and
- a hollow outer pole section received around the hollow center pole section, wherein the outer pole section has both protruding and intruding regions on its inner surface,
- wherein the protruding and intruding regions on the exterior of the inner pole section mate with the protruding and intruding regions on the interior of the center pole section, and wherein the protruding and intruding regions on the exterior of the center pole section mate with the protruding and intruding regions on the interior of the outer pole section, and wherein the wall thickness of the successive pole sections ac-e is progressively thicker moving outwards from the center pole section of the utility pole, and
- wherein the protruding and intruding regions become progressively less pronounced moving farther outwards from the center of the utility pole such that the successive pole sections are progressively smoother moving outwards from the center pole section of the utility pole.
