Abstract
Abstract A method forming, in a simple manner, corner joints or the like in structures, such as articles of furniture incorporating panels of chipboard. A typical corner joint is formed using a connecting member in the form of a length cut from an extrusion of constant cruciform cross-section. Adjacent edges of two panels defining the corner are secured in respective diagonally opposite channels of four V-section channels defined by the extrusion, one of the two remaining channels which faces outwardly from the corner being occupied by a filling member. The longitudinally extending edge faces of the two webs of the cruciform cross-section which extend outwardly may be flush with the adjoining outer surfaces of the panels and the filling member to present the appearance of inlays.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
186 words
A structure having a plurality of structural components connected together, comprising: first and second planar panels each having opposite inner and outer parallel major faces and an edge face extending perpendicular to said major faces from one of said major faces to the other; a unitary cruciform-shaped connecting member having throughout its length a uniform cross-section, said connection member having a longitudinal axis and four longitudinally extending webs extending radially from said longitudinal axis at intervals of 90° around said axis, said webs terminating in free longitudinally extending edges, each of said panels being positioned within a respective diagonally opposite angle of said cruciform-shaped connecting member with an inner major face secured to one of said webs and an edge secured to another of said webs, said first and second panels being mutually perpendicular to one another; and a filling member positioned within the angle of said cruciform-shaped connecting member which is between the angles receiving said first and second panels, the outer major face of each of said panels being exposed up to the edge of the web to which its edge face is secured.
Claim 2
Dependent Claim
