Projection module for large-area projection screen, has one frame part that is movable opposite to another frame part in displacement direction, and spring unit that produces small reset force during movement between frame parts

摘要

The module has a projection shield (2), in which display details of an image are projected in a projecting direction. A frame is provided for fastening the module at a projection screen stand, which bears the module. The frame has a frame part (11) that bears the shield, and another frame part (12) that fastens the former frame part to the stand. The latter frame part is movable opposite to the former part in a displacement direction that is transverse to the projecting direction. A spring unit (13) produces a small reset force during movement between the two frame parts.
