Abstract: A partition wall arrangement, in particular for offices, comprises at least a support section for the vertical support of the partition wall arrangement, the support section having a longitudinal direction, and at least one arrest line, which extends in the longitudinal direction and has snap-in holes for the locking engagement of objects to be joined thereto.

Abstract: An extension panel for connection to a lower panel of the type having vertical uprights defining upper ends and including a utilities passageway extending along an upper edge of the lower panel for receiving utility conduits therein. The extension panel includes a pair of space-apart upright posts, and at least one beam extending between the posts and rigidly interconnecting the same. A pair of structural members extend downwardly from the lower ends of the posts to engage the lower panel and rigidly interconnect the extension panel and the lower panel. The structural members are laterally spaced-apart to define a downwardly-opening utilities opening therebetween. The utilities opening is positioned in alignment with the utilities passageway of the lower panel to permit utilities conduits to pass through the utilities opening when the extension is secured to the lower panel.

Abstract: A knock-down portable partition includes a rigid panel frame having a central portion. The partition includes at least one cover panel covering at least a portion of the central portion of the rigid panel frame. Connectors detachably mount the cover panel on the panel frame to facilitate assembly and removal of the cover panel on the panel frame. The rigid panel frame includes at least two vertical posts having an upper end, a lower end, and opposite side faces. The opposite faces have at least two beam connection ports thereon positioned adjacent the upper and lower ends of the associated one of the posts. The panel frame also includes upper and lower beams extending generally horizontally between the vertical posts adjacent the upper and lower ends thereof, and interconnecting the vertical posts adjacent the connection ports. The panel frame includes quick-disconnect connectors such as movable lock members positioned on one of the posts and the beams adjacent the connection ports.

Abstract: A connector arrangement for use with an interior space-dividing wall system including portable upright panel assemblies each having an end edge defined by a vertically elongate rail and attached to an upright support post in supportive engagement with the floor. The connector arrangement includes a connector ring which clampingly engages the side walls of at least two adjacent support posts to interconnect two adjacent panel assemblies, for example in right-angled relation with one another.

Abstract: A wall system includes a wall section, such as a section of a partition, having a horizontal frame defining a horizontal row of attachment sites, such as a row of slots. An adjustable bracket includes a pair of vertical blades constructed to engage selected ones of the attachment sites, and further includes at least one telescoping horizontal support spanning between and supported by the pair of vertical blades, and still further includes universal connector brackets for engaging the telescoping horizontal support. The horizontal spacing of the blades can be adjusted to accommodate a component, and the telescopingly adjustable horizontal support can be adjusted to reach between the blades. The universal connectors adjustably engage the horizontal support and include slots to facilitate attachment to connectors on a back, a bottom, or sides of the component.

Abstract: A modular partition is composed of a plurality of posts, panels and shelves detachably interconnected therebetween. Disposing different specifications and varied amounts of the panels between the posts according to specific requirement can form partition walls with varied arrangements. The shelves disposed between any two of the walls can be mounted on any one of the panels to obtain desired heights.

Abstract: A modular office system incorporating wall panels with interlock edges to facilitate assembly. The substantially planar panels include a plurality of tabs extending from one side edge of the panel. The tabs are lockingly received within corresponding slots of an upright support member. To prevent disconnection of the panels, a retractable fastener bar can be selectively slid into locking engagement with the support member. The fastener bar is positioned within the panel and movable between a retracted position and an extended position engaging the upright support. A threaded fastener may be used to prevent sliding movement of the bar.

Abstract: A panel frame member defines an inner surface and has a sidewall with a row of slots therethrough for receiving support hooks of hang-on accessory units. The panel frame member includes a flexible light seal having a base portion fixed to the inner surface adjacent at least one of the slots. The light seal includes a flap connected to the base portion and extending over the slot to block light passage through the slot. The flap flexes inwardly upon insertion of a support hook to permit installation of a hang-on accessory unit.

Abstract: A demountable wall system mountable between, but not attached to, the floor and ceiling of a building constructed of a plurality of wall sections, each wall section including at least one upper horizontal framing member having opposed upper and lower slots; a plurality of spaced, parallel vertical framing members having opposed side slots facing side slots of adjacent vertical framing members; at least one horizontal lower member having opposed upper and lower slots; at least one vertical rectangular panel with upper, lower and opposed side edges inserted into facing slots of adjacent framing members; a floor mounting member inserted into the lower slot of the lower horizontal framing member; a vertically adjustable closure member inserted into the upper slot of the upper member to close the space between the ceiling and the upper horizontal framing member; and first and second door jamb attachment plates fitted into facing slots of adjacent vertical framing members for mounting of a door.
