Abstract
Abstract A corner structure for use in shelves, cabinets, boxes, and similar box shaped objects is described, wherein rectangular and/or polygonal panels are assembled by means of a rod-shaped junction of substantially hourglass cross-section. The junction is provided with or may be used in combination with separate uniting members having projections designed to be attached to the panels by means of screws or in other suitable manner.

Claims Analysis
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
Dependent 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 3
Dependent Claim
72 words
A corner structure according to claim 1, characterized in that the projections of the junction form parts of separate, flat uniting members having a body width equal to that of the junctions, said body of a uniting member having a projection on each side forming an angle with the body, the projections themselves forming an angle, corresponding to the angle, under which the panels are to be assembled to form a corner.
Claim 4
Dependent Claim
26 words
A corner structure according to claim 1, characterized by junctions of a length corresponding to the border length of the panels used in the corner structure.
Claim 5
Dependent Claim
55 words
A corner structure according to claim 1, characterized in that a junction is used, having throughgoing slots at the narrowest part of the hourglass-shaped cross-section, into each of which slots a flat uniting member has been inserted, and the ends thereof have been bent the same way to bear against slanting surfaces bounding the hourglass-shape.
