Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
123 words
A skeleton tower comprising a plurality of vertically stacked, modular sections, each section including a plurality of vertical legs spaced about the periphery thereof, the vertical legs of one section being in aligned, end-abutting relation with the legs of the adjacent section, means connecting the legs together at the abutting ends, said means comprising a connector tube fixedly connected to each end of each leg, the tubes at the abutting ends of the legs forming a pair, the longitudinal axes of the tubes being in angular relation to the longitudinal axes of the legs, the pair of connector tubes at the abutting ends of the legs being aligned with each other, and fastening means traversing said tubes and clampingly joining the tubes together.
Claim 2
Dependent Claim

A skeleton tower comprising a plurality of vertically stacked, modular sections, each section including a plurality of vertical legs spaced about the periphery thereof, the vertical legs of one section being in aligned, end-abutting relation with the legs of the adjacent section, means connecting the legs together at the abutting ends, said means comprising a connector tube fixedly connected to each end of each leg, the tubes at the abutting ends of the legs forming a pair, the longitudinal axes of the tubes being in angular relation to the longitudinal axes of the legs, the pair of connector tubes at the abutting ends of the legs being aligned with each other, and fastening means traversing said tubes and clampingly joining the tubes together.
Claim 3
Dependent Claim
65 words
The structure of claim 1 wherein said fastening means comprises nut and bolt combination including a bolt positioned on the interior of the pairs of connector tubes, and a nut lockingly engaging one extremity of said bolt so as to be maintained in frictional engagement with one end of one of said tubes, whereby said tubes are maintained in locked, aligned engagement with one another.
Claim 4
Dependent Claim
23 words
The joint structure of claim 1 wherein said pairs of connector tubes have abutting end faces which are angular to a horizontal plane.
Claim 5
Dependent Claim
22 words
The joint structure of claim 1 wherein said pairs of connector tubes have abutting end faces which are in a horizontal plane.
