Total Claims: 5
Claim 1
Independent Claim
85 words
A corner structure for use in shelves, cabinets, boxes and similar boxshaped objects, which are made from rectangular panels, said corner structure comprising a recessed rod-shaped junction of substantially hourglass-shaped cross-section into the recesses of which the borders of the panels are received, said junction having projections extending from each of the recesses to bear against the inner surfaces of the panels to be assembled at a corner, said projections being designed so that they can be attached to the panels by suitable fastening means.
Claim 2
