A closure assembly of an opening of or in a building or like structure, said closure assembly including at least two mutually pivoted panels mounted with the mutual pivot axis at least substantially vertical and so as to be movable between a closed condition whereby said at least two panels at least substantially in mutual alignment provide at least a partial closure of said opening in or substantially parallel to the plane of the opening, and an opened condition whereby said at least two panels, mutually disaligned by having pivoted mutually towards each other, are substantially clear of the plane of the opening and where one of each, or all of at least two panels, lie at an acute angle or parallel with respect to the plane of the opening, wherein one of said panels is pivoted by an at least substantially vertical pivot axis substantially in the plane of the opening at and/or adjacent a vertical periphery of said opening, and wherein the distal region of the other panel is supported by at least one supporting runner, wherein the supporting runner running on a support track which, at least in part is skewed, angled or angling, cranked or curved with respect to the plane of said opening, has the affect of allowing the spacing of the supporting runner out of the plane of said opening at/or adjacent said proximal periphery, and wherein a locking pin is provided fixed relative to said structure, said locking pin positioned to engage at a distal region of said distal panel against an outwardly facing surface of said distal panel when said panels are at and proximate to its closed condition to capture said distal panel from moving outwardly.
