A partition construction is provided for subdividing a building workspace wherein a first panel has a first frame with a horizontal top frame member and a vertical first side frame member, a second panel has a second frame with a horizontal bottom frame member and a vertical second side frame member, and a connection system for connecting the first and second panels in a stacked arrangement to form a first partition stack. The connection system includes at least one stacking connector which has fastener apertures proximate to each end of the connector. The fastener apertures in the stacking connector are in a predefined pattern identical to the fastener aperture pattern in the first and second side frame members. The connection system also includes a horizontal rail adapted to vertically align the top frame member of the first panel and bottom frame member of the second panel.

Stacking panel and off-module panel connections

A partition construction includes a partition frame having opposing vertical edges and upper and lower frame members each defining a repeating pattern of configured apertures and holes extending horizontally between its vertical side edges. The configured apertures are '+' or 'T' shaped, and include at least a smaller lower section and an enlarged middle section. Cover panels are attachable to the partition frame by top locator/connectors that engage the smaller lower section of selected apertures in the upper frame member, and by bottom connectors that engage an upper one of the holes in the lower frame member. The cover panels are shaped to leave the enlarged middle section of the configured apertures open, so that they can receive a component-supporting bracket or an off-module partition supporting bracket to the primary partition frame. A U-shaped 'off-module' connector is provided having a pair of hooked legs for engaging a selected one of the apertures in the enlarged middle section thereof, and a rear section configured for connection to the end of an off-module partition frame. The partition frame includes a pair of leveling members each including downwardly disposed end sections. A floor channel is provided having a locking wall spaced above a floor-engaging wall. The locking wall includes key hole apertures having a large end for vertically receiving the end sections of the leveling members and further having a small end for horizontally receiving the end sections of the leveler. The locking wall includes marginal material around the small end for engaging a recess on the end sections of the leveler to retain the leveler in the key hole apertures.

Partition construction including interconnection system and removable

A dual worksurface support is provided for electronic data processing equipment and the like, and includes two separate worksurfaces adapted to support different pieces of equipment thereon. The worksurfaces are interconnected by a linkage assembly which permits vertical adjustment of one of the worksurfaces with respect to the other, and includes left and right hand linkages located at the opposite sides of the respective worksurfaces, which rotate about at least one horizontal pivot axis. A rigid stabilizer bar has its opposite ends fixedly connected with the two linkages at locations concentric with the horizontal pivot access, such that rotation of one of the linkages is transmitted through the stabilizer bar to the other linkage to ensure that the opposite sides of the adjusted worksurface move vertically together without sagging or binding. A releasable lock may be connected with the stabilizer bar to retain the adjusted worksurface at selected heights, and telescoping pedestal may be provided with a quick disconnect actuator mount which permits replacement of the actuator without disassembly of the pedestal.

Adjustable dual worksurface support

An adjustable keyboard support includes a rigid support arm, and a keyboard support pivotally connected to the rigid support arm at a joint comprised of a ball and seat arrangement. The joint includes a retainer that both holds the ball on the seat and further adjustably frictionally engages the ball to resist the rotation of the keyboard support with respect to the support arm during keyboard manipulation. The adjustable keyboard support further includes a mounting bracket slideably and pivotally connected to an associated worksurface, permitting the keyboard to be moved between a raised use position and a retracted storage position. A lift assist is provided to counterbalancing support the weight of a keyboard placed on the keyboard support, and in the preferred embodiment is comprised of a self locking gas strut that automatically locks the arm in a given position. The gas strut attaches to a bracket that can be adjustably moved between high lift force and low lift force positions.
