1,156,831. Pivoting windows; hinges; window operating-mechanism. HEINZ MATHES K.G. 28 July, 1966 [28 July, 1965], No. 33918/66. Headings E1J, E2F and E2M. A main window framer 1 and hinged sash frame 2 are constructed from U-section metal (aluminium) or synthetic material bar having an open face disposed towards the interior side of the window and to the ends of the arms of the U-section, as by flanges 3, 4 are attached cover insulating strips, e.g. wood laths 5, 6 closing the open faces. The corner joints of the frames may be made by L-plates 7, Fig. 7 inserted in the bar sections and fixed by adhesive screws &c., or welding on the inside of the sections. The interior of the section may be devided into two chambers 12, 13 Fig: 3. one, viz 12, for the insertion of the corner plates 7, and the other chamber viz. 13, for accommodating the hinge plates 14 and the operating rods 9 or 8 for movable hinge pins 16 located in the corner hinge plates 14 at each of the four corners and intermediately so that the pins 16 at 'either side may be selectively withdrawn from their co-operating sockets on the main frame, and render the window either right handed or left handed opening. To this end the hinge plate 14 has an opening 26 Fig. 4 with a guide tongue 25 which with the lath 6 forms a guide for an actuator 29 connected in recess 32 in pin 16 and having lugs 30 engaging corresponding apertures in an operating rod 8 or 9 operated from a handle 21, which may withdraw all the pins from the hinge sockets 19 and insert a horizontally disposed hinge pin 17 into its socket 14, to provide a horizontal axis of rotation for the sash. Socket 23 being pivotally mounted on the main frame. The internal space of the bar sections may be filled with thermal foamed insulating material.
