Abstract: A double sliding door arrangement cooperating with a double-wide door opening formed in an upright wall. A top header beam extends across and defines the upper extremity of the door opening. A pre-tensioning arrangement mounted on and extending lengthwise of the top header beam causes the header beam to be deflected upwardly into a shallow bowed shape. A support track is fixed to and extends lengthwise of the header beam and horizontally for predetermined distances along and rigidly fixed to the wall adjacent right and left sides of the door opening. Right and left slab doors are supported on and vertically suspended downwardly from said track in sidewardly co-planar relationship, and are movable along said track between closed and open positions. The doors in the closed position vertically load and downwardly deflect the header beam, whereby the initial upwardly bowed shape minimizes outward swinging between opposed inner edges of the doors when in the closed position.

Abstract: A snap-on attachment structure for attaching a side skin to an upright frame of a wall system. The attachment structure includes resilient attachment strips secured to the rear of the skin and extending along upright edges thereof. Each strip cooperates with a projection formed on an upright frame member and extending vertically therealong. The snap-on strip has a pair of cantilevered spring legs which protrude outwardly in angled relationship. The spring legs adjacent outer ends are provided with coil-shaped head parts which protrude inwardly toward one another. The head parts have hollow arcuate configurations and move into gripping engagement with shallow arcuate recesses formed on opposite sides of the projection.

Abstract: A floor panel for a raised access floor system, including a shallow metal pan with a bottom wall and a shallow upwardly-opening compartment. The bottom wall has a plurality of first hollow projections projecting upwardly therefrom, which projections adjacent upper ends thereof having sidewardly projecting rib structure. The bottom wall also has a plurality of microfeatures which project upwardly through a lesser extent. The number of microfeatures is substantially greater than the number of projections. The pan side walls and bottom wall are free of openings therethrough. A mass of solidified concrete fills the compartment. The floor panel is supported on a pedestal having a base which has clamping and mounting features integrated thereon for engaging grounding wires and cable management members.

Abstract: A sliding glass door has a pair of rollers mounted adjacent the upper corners, which rollers are cantilevered rearwardly and cooperate with a horizontally elongate L-shaped support track which spans horizontally across the door opening and across an adjacent upright wall panel to enable the door to move into an opened position wherein it overlies the adjacent wall panel. The height of the roller-track arrangement and of the structure defining such arrangement, as it extends across the upper edge of the door opening and the adjacent wall panel, is minimized to provide improved aesthetics.

Abstract: A pair of upright wall panels are each provided with a sidewardly spaced pair of generally parallel but inclined guide grooves extending vertically along the outer face of the upright frame edge rails. A connector assembly including a main activator rod having a pair of wedge members threaded thereon in spaced relationship therealong is positioned between the opposed upright edge rails. The wedge members have wedgelike edge flanges which protrude into the grooves of the opposed upright edge rails. Rotation of the activating rod causes the wedge members to simultaneously move relative to the rod in opposite directions to effect gripping engagement with the groove walls to simultaneously effect a drawing together of the edge rails and alignment thereof.

Abstract: A seating system is provided having a chair with a storage bay below the seat thereof and a cart-like ottoman which is storable within the storage bay. A connector arrangement is provided within the storage bay which positively engages the ottoman with the chair when the ottoman is rolled into the storage bay to a fully docked position. The chair and ottoman both include casters and the connector arrangement allows for both components to be moved simultaneously to a new position. In particular, preferably the chair includes casters on the front thereof and a handle on the back whereby lifting of the handle allows the chair as well as the docked cart to be tilted upwardly and rolled in unison to a new position.

Abstract: A storage cabinet for use in an office environment including a stationary housing defining a hollow interior which opens frontwardly, and a drawer-type cart defining storage space thereon which is movable into the interior of the housing when not in use and out of the housing when access to the storage space is desired. The cart mounts thereon a wheel or roller arrangement on a lower front end thereof for engagement with a floor surface, and a roller arrangement at an upper rear end thereof which is engaged within a track or rail mounted along a top of the housing so as to suspend a rear end of the cart therefrom.
