Abstract

Abstract A lightweight support structure for electromagnetic and light reflectors including at least two rigid compression rings of any diametrical ratio held vertically spaced and parallel by a plurality of rigid vertically extending peripheral columns and two or more flexible cable sets vertically spaced and parallel with the compression rings. Nodes or junctures on the cable sets are adapted to remain fixed in space with respect to the compression rings by a series of tangential and radial cables and thus support rigid vertical internal columns which in turn support the reflector. The internal rigid columns may progressively increase in height from a central hub to the outermost periphery of the compression rings for supporting a reflector dish of parabolic configuration.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 272 words
A support structure for electromagnetic and light wave reflectors comprising: at least two substantially planar and rigid enclosure members, parallel spaced from one another about a common axis perpendicular to the planes of the enclosure members; a plurality of rigid outer columns spaced about and between the peripheral surfaces of said enclosure members and operable to immovably secure said enclosure members to one another; at least two spaced sets of cables; each set including a plurality of flexible radial cables connected to and between selected opposing attachment sites on said rigid members, said radial cables tautly extending between opposing sites parallel with said enclosure members and joining a hub located at the substantial axial center of said enclosure members; each set including a plurality of flexible internal cables connected to and between said radial cables at selected attachment sites on said radial cables substantially equidistant from the common central axis of said enclosure members to define one or more polygonal internal members; and each polygon attached by at least one restraining member to selected attachment sites on said rigid members, said restraining member operable to restrain tangential movement of said polygons with respect to the enclosure members; a plurality of rigid internal columns connected to and between said cable sets, each of said internal columns connected to a respective set at the juncture of one of said radial cables and one of said internal cables; and a plurality of flexible cross cables, each of said cross cables connected to and between opposing ends of adjacently spaced rigid columns in planes containing the vertical axis of said enclosure members and said rigid columns.
