A window frame or window and door frame comprises two or more quadrilateral sub-frames for example four window frames 21 shown in Figs. 3 and 4, including at least two sub-frames in a common vertical plane, together forming a larger quadrilateral, connected together at each of their adjacent sides by an interposed coupling bar 20, Fig. 4, and a coupling transom 15, Fig. 3, and enclosed by a coupling head 16, Fig. 3, a coupling sill 17, Fig. 3, and two vertical coupling jambs 18 and 19, Fig. 4, extending integrally along at least two frames, the coupling bar and transom head, sill and jambs, extending completely across the depth of the sub-frames and having projections 23 or 25 to engage in grooves in the sub-frames. Sub-frames may be connected at any required angle to each other as shown in Figs. 5 and 6, filling pieces 27 being interposed between two coupling bars 20. The sub-frames are made of wood and may receive window-panes, casements, sliding windows, or steel window frames. Door frames, including French casements, may be coupled to one or more window frames. The joints between the various members may be glued, painted, screwed or otherwise joined.
