Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
234 words
In an office cabinet comprising a pair of end members each formed from a planar sheet metal blank bent so as to provide a plane face and edge faces extending around at least part of the periphery of the plane face, which edge faces are substantially wider than the thickness of the sheet metal and substantially narrower than the width of the plane face, the plane face forming a generally rectangular outer side surface of the cabinet and the edge faces adjoining said side face at least at the front, top and rear of the cabinet, the improvement wherein said sheet metal blank includes: a generally rectangular area which corresponds to said plane face and has at least some rounded corners and straight edges extending from said corners, edge forming portions contiguous with said area along said straight edges, continuation of at least some of said edge forming portions projecting beyond the junction of one of said straight edges with said rounded corner, and the blank being bent along said edges to turn said edge forming portions perpendicularly to the plane face and said continuations of said edge forming portions being curved to adjoin the rounded corners of the plane face such that the edge face formed by said edge forming portions and the continuations thereof curves around said rounded corners whereby the end member mimics the shape of a board with rounded corners.
