A frame for reinforcing a handhole of a round metallic utility pole, includes a generally elliptical body defining a major axis and a minor axis and forming a generally elliptical outer periphery, and a generally elliptical inner periphery bordering an opening extending through front and back sides
A frame for reinforcing a handhole of a round metallic utility pole, includes a generally elliptical body defining a major axis and a minor axis and forming a generally elliptical outer periphery, and a generally elliptical inner periphery bordering an opening extending through front and back sides of the body, the opening defining a center axis of the frame. A flange is formed integrally with the body and projects forwardly therefrom at a location spaced inwardly from the outer periphery, wherein the flange is separated from the outer periphery by a forwardly facing shoulder surface of the body. The flange includes an outer flank facing outwardly and intersecting the shoulder surface, wherein the flange outer flank forms an oblique angle with the center axis as seen in a sectional view taken along the major axis, and lies substantially parallel to the center axis as seen in a sectional view taken along the minor axis.

What is claimed is: 1. A frame for reinforcing a handhole of a round metallic utility pole, the frame comprising a generally elliptical body defining a major axis and a minor axis and forming a generally elliptical outer periphery, and a generally elliptical inner periphery bordering an opening extending through front and back sides of the body, the opening defining a center axis of the frame, a flange formed integrally with the body and projecting forwardly therefrom at a location spaced inwardly from the outer periphery, wherein the flange is separated from the outer periphery by a forwardly facing shoulder surface of the body, the flange including an outer flank facing outwardly and intersecting the shoulder surface, wherein the flange outer flank forms an oblique angle with the center axis as seen in a sectional view taken along the major axis, and lies parallel to the center axis as seen in a sectional view taken along the minor axis. 2. A utility pole comprising: a metallic shaft having a round base in which a handhole is formed, the handhole being of generally elliptical shape defining major and minor axes, the major axis extending parallel to a longitudinal axis of the shaft, the handhole defining a center axis extending perpendicular to the longitudinal axis, an edge of the handhole including first and second portions intersected by the major and minor axes, respectively, the first portion extending substantially parallel to the center axis, and the second portion forming an oblique angle relative to the center axis; and a reinforcing frame disposed in the handhole, the frame comprising a generally elliptical body defining major and minor axes and forming a generally elliptical outer periphery, and a generally elliptical inner periphery bordering an opening extending through front and back sides of the body, the defining opening defining a center axis of the frame, the frame's major and minor axes and center axis coinciding with the handhole's major and minor axes and center axis, respectively, the body including an integral flange projecting forwardly at a location spaced inwardly from the outer periphery, wherein the flange is separated from the outer periphery by a forwardly facing shoulder surface of the body, the flange including an outer flank facing outwardly and intersecting the shoulder surface, wherein the flange outer flank forms an oblique angle with the center axis as seen in a sectional view taken along the major axis, and lies parallel to the center axis as seen in a sectional view taken along the minor axis, the line of intersection between the flange flank and the shoulder surface being spaced inwardly from the handhole edge to form an elliptical groove therebetween in which a full penetration groove weld is formed to secure the frame to the shaft.
