Abstract
Abstract This invention relates to a pole structure comprising one series of alternate sides in a first form and another series of alternate sides in a second form, said first form comprising structural plates which are joined by one or more bracing members, and said second form comprising shrouds attached to the structured plates to form an enclosed pole structure, at least one of the other series of alternate sides having the shrouds removably or hingedly attached.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
164 words
A pole structure for supporting electrical power transmission lines or the like, said pole structure being at least four sided in cross section, one pair of opposing sides of the pole structure formed by substantially imperforate structural plates which extend continuously for substantially the entire height of the pole structure, the other pair of opposing sides of the pole structure being formed of open lattice-type bracing which extends continuously for substantially the entire height of the pole structure in interconnecting relationship with said one pair of sides, the improvement which comprises substantially imperforate shrouds hinged along corresponding longitudinal edges to at least one side of the pole structure in said one pair, said shrouds arranged in end-to-end relationship adjacent said other pair of sides and forming substantially continuous uninterrupted coverings for said other pair of sides for substantially the entire height of the pole structure, whereby said open latticetype bracing is fully concealed and the pole structure has an aesthetic appearance imparted to it.
Claim 2
Dependent Claim
164 words
A pole structure for supporting electrical power transmission lines or the like, said pole structure being at least four sided in cross section, one pair of opposing sides of the pole structure formed by substantially imperforate structural plates which extend continuously for substantially the entire height of the pole structure, the other pair of opposing sides of the pole structure being formed of open lattice-type bracing which extends continuously for substantially the entire height of the pole structure in interconnecting relationship with said one pair of sides, the improvement which comprises substantially imperforate shrouds hinged along corresponding longitudinal edges to at least one side of the pole structure in said one pair, said shrouds arranged in end-to-end relationship adjacent said other pair of sides and forming substantially continuous uninterrupted coverings for said other pair of sides for substantially the entire height of the pole structure, whereby said open latticetype bracing is fully concealed and the pole structure has an aesthetic appearance imparted to it.
Claim 3
Dependent Claim
37 words
The structure of claim 1, in which each shroud is hinged to the pole structure along both of its longitudinal edges for opening selectively in either of two directions to provide access to the pole structure interior.
Claim 4
Dependent Claim
67 words
The structure of claim 2, and each shroud having longitudinal edge flange portions projecting inwardly from the plane of the shroud along its full length and overlapping adjacent edge portions of said one pair of sides formed by said imperforate structural plates, said overlapping edge flange portions imparting to said one pair of opposing sides a symmetrically recessed appearance for the entire height of the pole structure.
Claim 5
Dependent Claim
25 words
The structure of claim 3, and said pole structure tapering in cross section gradually toward the top of the pole structure on all sides thereof.
