  • Patent number: 4438613
    Abstract: According to the present invention, a new suspended ceiling system is possible of the type having a plurality of removable panels which are supported below a grid network. The grid network comprises structural elements interconnected by junction members with the cells of the grid network sized to receive a panel about the periphery thereof. These structural members cooperate with framed panel members to accurately align adjacent panels and position them at a certain height below the grid network. Access to the area above the panels is easily obtained by removal of any of the panel members. Each panel is urged into abutting contact with the grid network to provide a seal therewith such that the area above the ceiling may be used as a return air plenum. The particular frame member for the panels facilitates mechanical connection about and to the body member of the panel and also simplifies removal of the panel.
