ABSTRACT:
A hybrid sliding-pivoting door or window structure comprises one or more pairs of cooperative panels each including a first swinging panel and a second sliding panel. The sliding panel can be moved from a fully closed position in which it is end-to-end with the swinging panel to a semi-open position of the structure in which it is juxtaposed face-to-face with the swinging panel and both panels can then be swung as a unit to fully open the structure and provide substantially unimpeded access across the width of an opening in which the structure is located. The sliding panel is received in a fixed track section when in the fully closed position and moves into a swinging track section associated with the swinging panel.
