Compact projection television system

机译:紧凑型投影电视系统

摘要

A compact projection television system is disclosed which includes an enclosure having a movable front portion hingedly attached to a fixed rear portion so as to be movable between an open and a closed position. When the movable portion is in the closed position a large viewing screen, projection optics and a television receiver are hidden from sight within the enclosure. When the movable portion is rotated to the open position, the viewing screen elevates and the projection optics unfold to ready the projection television system for use. The raising of the screen and the unfolding of the optics are caused by linkages connecting those members between the fixed and movable portions of the enclosure.
