The invention refers to a three-dimensional corner joint designed to be held together by an assembly fitting. Each end surface of three conjoining bars in the corner joint is adapted for the building of partly two planed, triangular shaped surfaces (5, 6) which cut each other at an angle of 120 degrees, and whose intersecting lines (A-G) extend themselves between two diagonally opposing longitudinal corners (A-K, G-L) of the bars in question and form an angleαwith this, of which angleαis such that the transverse is alike with square root of 2, partly a first track which extends itself along the above mentioned intersecting lines (A-G). The mounting bracket is partly comprised to a corner piece bearing against the three planed surfaces of corner joint, partly a locking washer modelled in an opening which is formed of the three other slots as well as a screw for joining the corner joint with the locking washer.<IMAGE> |
