The invention relates to a staircase system featuring modular construction components, wherein the framework of the staircase itself is produced by assembly of modular components paired one with the next in sequence so as to form a bearing structure for the single stair treads. The modular components are prismatic in shape and slot together reciprocally in a number of positions one relative to the other so as to a give a variety of reciprocal positions-at least, in the vertical plane. Each modular component consists of a length of molding whose cross section has an elongated profile which remains constant throughout. The molding is disposed so that its main longitudinal axis is horizontal following assembly. The reciprocal type of connection between one component and the next is brought about by tongues and grooves formed on the vertical side faces of one component and on the mutually-opposed and inwardly-set vertical faces of the next component, between which the first component is partially inserted. Once the components are interlocked, the tongues and grooves inhibit any relative movement whatsoever of either component other than parallel to the horizontal axes of the individual moldings used for their formation. |
