Light box for integration with false ceiling type wall, has hinge allowing tilting movement of inner frame, where tilting movement successively combines phase of vertical translation and phase of rotation around horizontal rotation axis

摘要

The box (1) has an inner frame (2) movable at a base in which stretched sheets (7, 8) are fixed. An envelope (3) is provided for receiving the inner frame, and a hinge (10) connects the inner frame to the envelope. The hinge allows tilting movement of the inner frame relative to a housing, where the tilting movement successively combines a phase of vertical translation and a phase of rotation around a horizontal rotation axis (9). The horizontal rotation axis is eccentric with respect to the inner frame.
