Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
153 words
A frame structure comprising fixing devices, a plurality of pyramidal frame units each having a base of pyramidal shape provides by base members rigidly connected together at their ends providing corners thereof and side members each attached at one of its ends to a corner of said base and at its other end to a respective cooperating one of said fixing devices, said frame units being positioned with each base having a corner only thereof adjacent a corner only of a second one of said bases and each said corner having a lateral cut, connecting members each consisting of a block member attached to one of said base corners at the corner cut thereof and having an axial bore, said block members of adjacent base corners facing one another, and assembly bolt means extending through the axial bores of facing block members joining said block members and thereby the adjacent base corners together.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
67 words
A frame structure as claimed in claim 1 wherein said frame units are further positioned with certain of said bases each having at least two of their corners only thereof adjacent to corners only of further of said bases, additional ones of said connecting members are connected to said further base corners and additional ones of said assembly bolt means bolt said additional adjacent connecting members together.
