ADJUSTABLE DOOR AND DOORWAY CONSTRUCTION

摘要

A door and doorway construction (50) includes a doorway structure (51) having a lock jamb (64), a hinge jamb (68), and a header defining a doorway opening (52). An adjustable door (53) is constructed to fit mateably into the doorway opening (52). The doorway structure (51) includes an overhead expressway construction (60) configured to structurally support a weight of the door (53) and further adapted to carry utilities over the doorway opening (52). The doorway structure (51) is vertically adjustable to align the expressway construction (60) with adjacent wall units, which results in size changes in the doorway opening (52), and the door (53) is adjustable to define an adjustable vertical height shaped to fill the doorway opening (52) despite the size changes. In another form, the door (53A) is slidably mounted to the doorway structure (51A) by a door-supporting boom (330) that includes a trolley (331) rollingly supported by the doorway structure (51A) and a downrigger (333) that is rigidly supported on the trolley (331).
