Abstract: A chair particularly useful for an auditorium utilizes spherical bearings to mount the bottom of the chair to upright standards. The spherical bearing includes a base portion and a top portion that are secured to the chair bottom to hold the spherical bearing roller. An axle extends through each standard to engage the bearings to support adjacent chairs. The axles are threaded to receive a nut to secure the axles to the standards.

Abstract: A method and apparatus for installing electrical outlets in a wall panel assembly. The wall panel includes an open frame structure and front and rear panel inserts removably attached to front and rear faces of the frame structure. The rear panel insert is removed from the rear face of the frame structure, a cutout is formed in the front panel insert at a desired location for the outlet, a bracket is secured at one end thereof to the frame structure with another end thereof positioned proximate the cutout in the front panel insert, the outlet is positioned in the cutout in the front panel insert and secured to the other end of the bracket, and the rear panel is replaced against the rear face of the frame structure.

Abstract: A wall panel assembly for use in providing an open plan system to define separate areas. An L shaped connector bracket is utilized to join two panels together in an L configuration, three panels together in a T configuration, or four panels together in an X configuration. In each case one leg of the bracket is secured to an end edge of the first wall panel and the other leg of the bracket is secured to the end edge of a second panel. Where only two panels are being joined in an L configuration, a ball end edge of an L shaped trim post is positioned at one end edge in a socket groove defined by the connector bracket and rotated to bring another ball end edge of the trim panel into snapping coaction with a socket groove defined on another end edge of the connector bracket.
