Abstract:
Joint for the angular connection of a pair of hollow profile members ( 50 ) having an angular configuration corresponding to the angle of the assembled profile members ( 50 ) and comprising a slide base portion ( 2, 2′, 2 ″), a sheet metal portion ( 1, 1 ′) superimposed thereupon and a bolt ( 5 ) passing through the sheet metal portion ( 1, 1 ′) and screwed into a nut ( 4 ) mounted onto the base portion ( 2, 2′, 2 ″), wherein tightening of bolt ( 5 ) pushes upwardly extending surfaces on either side of portion ( 1, 1 ′) whereby their sharp edges indent the walls of the hollow profile members being connected. The indentation and efficient angular connection of the hollow profile members is enhanced through: a) forming of the sharp edges of the sheet metal to align an aberrant edge thereof in an indentation appropriate direction, b) appropriately orienting the sheet metal portion ( 1, 1 ′) to comply with a set of predetermined geometrical parameters and c) selectively employing varying embodiments of the slide base portion to obtain rapprochement of the points of indentation of the walls being indented.
