Abstract: A dual wall partition comprising, in combination, first and second generally planar panels, and hinge apparatus supporting the panels in generally parallel, generally opposed relationship, the hinge apparatus extending between the panels for permitting a range of movement of the panels relative to each other to vary the spacing therebetween from a maximum determined by the hinge apparatus to selected spacings which are less than the maximum and so that the panels remain substantially parallel throughout the range of movement.

Abstract: An accordian type folding door of the type disclosed in Holloway U.S. Pat. No. 3,233,147 in which each cover of the door is in the form of consecutive cover sections, connected to the door lazytongs in side by side relation, each of which cover sections defines a fold or pleat of the door and includes a pair of relatively wide slats of substantially equal width disposed on either side of a relative narrow slat, with such slats being pivoted together by inner and outer flexible sheets that are respectively adhered to the opposite faces of the respective slats; for each cover section of the door covers, the flexible sheets extend beyond the relatively wide slats thereof to define sheet end portions, with such sheet end portions of adjacent cover sections being clamped together by a spline that extends the height of the cover that the cover sections define.

Abstract: A suspension system for operable partitions providing for several degrees of lost motion freedom, wherein the suspension system comprises an overhead track, a series of discrete panels, and a pair of carriers for each panel to suspend the respective panels individually from the track for movement of the panels between the point of use and a storage area that is remote from the space being subdivided, with each panel having a trackway along its upper end mounting a pair of trolleys that are connected one each to the respective carriers for the panel, for movement of the panel in its plane relative to the carrier supporting it.

Abstract: A drop action panel arrangement for operable partitions of the multidirectional type, wherein the partition is made up of a plurality of discrete panels each having a pair of carriers riding on an overhead track to facilitate movement of the panels between the point of use and a storage area that is remote from the space being subdivided. The individual panels are vertically movable relative to their carriers and are arranged to be releasably supported on their carriers in an elevated position above the floor to arrange them for movement between points of storage and points of use. At the point of use the panels are released from dropping under gravity onto the floor for manual juxtaposition and squaring with adjacent panels to form the partition. The individual panels have adjustable base shoes for squaring of the panels, and a top seal arrangement for sealing the gap between the individual panels and the track.
