1. A door system, comprising:
a door frame including a header member having a guide rail, the guide having a central portion with a notch that extends upwardly from a lower terminal edge of the guide rail;
a panel hanger member slidably coupled to the header member;
a door panel coupled to the panel hanger member, the door panel having a handle end portion releasably coupled to the panel hanger member and a pivot end portion pivotably coupled to the panel hanger member, the panel hanger member and the door panel configured to slide in unison along the header member between a closed position and a fully open position along a longitudinal plane;
an interlock plate fixedly mounted to the handle end portion of the door panel and positioned to extend upwardly from the door panel, the interlock plate including a guide slot configured to slidably receive the guide rail of the header member, wherein in the fully open position of the door panel, the interlock plate aligns with the notch of the guide rail of the header member in a direction orthogonal to the longitudinal plane to facilitate pivoting of the door panel relative to the panel hanger member away from the longitudinal plane;
a lower pivot member fixedly connected near a lower portion of the door frame, the lower pivot member having an upwardly extending cylindrical protrusion, and the pivot end portion of the door panel having a U-shaped pivot recess, the U-shaped pivot recess being engaged with the cylindrical protrusion of the lower pivot member only when the door panel is in the fully open position; and
an interlock block connected to the panel hanger member and configured to rotate between a slide blocking position and a slide release position.
