ABSTRACT:
A system of sliding doors commonly called patio-doors, having a wooden structure and well adapted for a household use. This device comprises a wooden rectangular frame receiving two glazed panels, one of which is sliding. The latter is supported on its lower portion by rollers. In the upper portion of the movable panel, the guiding system is constituted by a spring-loaded runner, preferably a channel whose two flanges extend into two parallel grooves on the top of the slidable panel. To remove the sliding panel from the frame supporting it, the operator lowers the retractable runner; this releases the upper portion of the panel from the frame and allows it to swing outwardly. A safety device is provided to prevent accidental removal of the upper portion of the sliding panel from the frame. Also described is a patio-door unit comprising two sets of glazed panels, each having one sliding panel.
