ABSTRACT:
A projector mounting frame is fitted in the space above the suspended ceiling of a room. A traveling frame vertically movable in the mounting frame has means for support of a projector thereon. Drive motor and screws drive the traveling frame vertically so the projector can be driven from a position concealed within the space above the ceiling to a position below the ceiling where it can project onto a wall or screen in the room. A trim frame is hung on the traveling frame under the projector and has ceiling pads or tiles on it matching the rest of the ceiling to neatly close the ceiling opening when the projector is concealed.
