摘要

Improvements in the structure and assembly of truncated cone posts to support points of light on public roads and lines of electricity or telephone lines, characterized in that the stem of these posts is composed of a succession of frustoconical pieces of circular section and equal degree of conicity, but with a layout such that the major base of each hollow piece has a diameter greater than that of the smaller base of the immediate lower piece in the sequence, being therefore susceptible of an area adjacent to said larger base overlapping a corresponding length zone immediate to said lower base of the aforementioned lower immediate section in the succession, in such a way that a self-stability of all the said pieces is ensured whatever the total length of the shaft thus constituted, without the need to use auxiliary elements such as welding, screws or similar.
