multi-fold panel assemblies with skewed support track, and frame structure to fully frame panels and for setting into a buidling opening

摘要

A closure assembly (40) of an opening in a building including at least two mutually pivoted panels (41, 42, 43) mounted with the mutual pivot axis (44) at least substantially vertical. The panels are movable between a closed condition whereby the at least two panels at least substantially in mutual alignment provide at least a partial closure of the opening in or substantially parallel to the plane of the opening, and an opened condition whereby the at least two panels, mutually disaligned by having pivoted mutually towards each other, are substantially clear of the plane of the opening. A proximate panel (41) is pivoted by a vertical pivot axis substantially in the plane of the opening at adjacent a vertical periphery of the opening (45). The distal region of distal panel (42) is supported by at least one supporting runner. The supporting runner is guided by a support track (51) which is skewed with respect to the plane of the opening and has the affect of spacing the supporting runner out of the plane of the opening at the vertical periphery. The closure assembly further includes a frame structure to set into that is contiguous the perimeter of the opening to thereby fully frame the panels.
