Abstract: Chairs with improved ganging equipment comprising a vertically disposed open-ended keyway on one side of each chair and an interfitting key on the other side of each chair to allow the chairs to be ganged by engaging the key of one chair in the keyway of adjacent chair. Any of the ganged chairs can be separated by lifting it out of engagement with the adjacent chairs.

Abstract: A tablet arm attachment for a chair includes brackets with U-shaped channels and outwardly extending flanges to clamp the tablet arm to a support rod from which the tablet arm to a support rod from which the tablet arm is pivoted. A molded plastic bearing insert has a U-shaped channel portion complementary to the channel portion of the brackets to interfit therewith. A flap on the bearing insert permits the bearing insert to be folded over the support rod and provides a smooth, quiet, pivotal motion of the tablet arm which will not scratch the tablet arm.

Abstract: A folding table having a modesty panel employs a locking mechanism in the form of tab and hook assemblies to rigidify the table in the unfolded operative condition with the legs erect and the modesty panel in a position for use. The tab and hook assemblies are mounted on the panel and the tabs are received in slots in the adjacent leg assemblies to prevent hinged movement of the leg assemblies about their hinge axis. The hooks are rotatably and slidably supported in apertures in the tabs and are movable between a folded position and a leg embracing position. In the leg embracing position the hooks secure the tabs in the slots by preventing hinged movement of the panel.

Abstract: Disclosed herein is a pedestal base system for furniture in which base portions formed of pairs of duplex legs are easily assembled in interlocking splined fashion to form various base configurations for different articles of furniture. The vertical runs of each leg in a pair are welded to connctor tubes with the vertical axes of the connected vertical runs and tubes being in the same plane. The connector diameter and the diameter of the vertical tubular runs are dimensioned so that the legs in each leg pair are spaced from the legs in the other pair to provide clearance to facilitate assembly. The connector tubes of each leg pair are at a different vertical height and receive a vertical locking bolt or locking tube to secure the leg pairs in assembly. The leg pairs are easily assembled at the site by sliding the pairs together in the manner of a splined connection.

Abstract: The crank arm of a hinge lock mechanism acts as an over-center latch for a folding leg when the leg is in its extended position perpendicular to the table top and also in its retracted position parallel to the table top. The crank arm is pivotally connected at one end to a support plate on the bottom of the table and is pivotally linked to a support arm on the folding leg. When the crank arm is rotated downwardly, it moves the folding leg far enough away from an apron or abutment so that the leg can be manually swung from its extended position to its retracted position and vice versa. The crank arm is subsequently rotated back to its upper limit in either case to latch the leg in position. The hinge lock mechanism is entirely hidden from view by aprons when the table is upright.
