Earthquake resistant electronic equipment frame

An earthquake resistant electronic equipment support frame comprising a plurality of upwardly extending frame members and frame base means extending between the upwardly extending frame members to hold the upwardly extending frame members in fixed relative positions, the frame base means having proximate regions extending directly from the upwardly extending frame members, said proximate regions being of more massive construction than parts of the frame base means which are remote from the upwardly extending frame members, the proximate regions being rigidly secured to the upwardly extending frame members and formed with apertures for receiving screw-threaded members to mount the frame upon a support;

• wherein lower ends of the upwardly extending frame members are disposed at locations forming corners of a polygon and at least some of the proximate regions of the frame base means lie along sides of the polygon;
• wherein the frame base means comprises a plurality of base frame members comprising elongate intermediate elements extending along sides of the polygon and having end regions, the proximate regions of the frame base means being provided at opposite end regions proximate of each of the intermediate elements, the proximate regions comprising end members of the base frame members, the end members being separated by the intermediate elements and extending along and rigidly secured to the end regions of the intermediate elements;
• and
• wherein each intermediate element is of box cross-section and the end members are of solid block structure and are disposed within channels at the end regions of the intermediate elements.
