Coordinated system for removeable fastening of furniture elements to the bearing structure of a prefabricated wall

Abstract

In a prefabricated wall, a frame of the wall is formed by uprights and crossbars obtained from tubular bars. A coordinated connection system is aimed at removably fastening furniture elements to the frame using longitudinal undercut grooves made in the tubular bars. First and second clamp means for hanging furniture elements, such as shelves and wall hanging elements, engage with the undercut grooves arranged both in horizontal and vertical, and fasten the cantilevered supports to the tubular bars by screw tightening. The cantilevered supports carry, position and fix the furniture elements. Also first and second multiple joining means for bearing furniture elements, such as desk tops, or structural elements, such as support feet of the wall, engage with the undercut grooves and fasten the bearing or structural furniture elements to the tubular bars by screw tightening.
