Abstract
Abstract A corner construction for a table comprises an upright leg, a pair of horizontal side frame members, and means for clamping the side frame members into end abutting relation to the leg. The clamping means comprises a pair of clamping members, each clamping member comprising a flanged plate the flanges of which subtend an angle which is supplementary to the angle subtended between the flanges of the other plate, said angles defining the angle subtended between the side frame members when the latter are clamped in position.
