Abstract: A window buck having members forming a frame with the members including adjustable components enabling use of the buck in walls under construction of different thicknesses. Extruded front and rear components of each buck member are adjustably interengaged with one another and fixable in a desired relationship to suit the wall being constructed. External channels formed in the buck members are open lengthwise to permit reception of angular connectors for joining the buck members at their intersecting ends. The connectors may be of reusable rebar and removable upon completion of the wall. The components of each buck member are lockable by inserted fasteners. A modified window buck includes a central component for use in walls of extraordinary thicknesses. A further modified window buck may include buck members of unitary construction.

Abstract: Disclosed is a partition device that divides an original interior room into plural room sections which may be illuminated evenly and simultaneously by a common lighting fixture. This partition comprises one or more of wall panels (1, 2a-2d), connected to one another, which are upstanding from a floor toward a ceiling of an original room interior over a predetermined height. Each of the wall panels includes an opening 3, (4) along a common vertical axis. A single lighting fixture (5) is mounted within a space defined by cooperation of openings (3, 4) of the wall panels for illuminating, at the same time, all of room sections divided by the wall panels. The wall panels may comprise a main panel (1) and plural auxiliary panels (2a-2d) hinged to the center axis of the main panel.
