1. A video projector mount comprising:
- a first frame fixedly mountable above a finished ceiling and defining a video projector storing space within said frame;
a second frame vertically movable within said space between a top and a bottom position;
a plurality of shafts supporting said second frame on said first frame and along which said second frame is vertically movable;
ceiling finishing means for interfacing with said finished ceiling, said finishing means being attached to and suspended from said second frame and vertically movable therewith and being spaced sufficiently below said second frame for mounting a video projector to said second frame above said finishing means; and
drive means causing said shafts to operate in unison to drive said second frame in a vertical direction between said top and bottom positions within said space, whereby a video projector mounted to said second frame is movable out of said space within said first frame to extend below said finished ceiling when said second frame is in said bottom position, and whereby the video projector is movable into said space and the ceiling finishing means interface with said finished ceiling when said second frame is in said top position.

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.
