| 摘要 |
<p>The invention relates to a projector screen (1) comprising a projection surface (2), means (4) for hanging the projection surface, means for applying vertical tensile forces (FV) comprising weighting means (4) for the lower longitudinal edge of the projection surface, means for applying horizontal tensile forces (FH) comprising on the one hand two deformable elongate components (9, 10), each connected to one of the lateral edges of the projection surface, and on the other hand weighting means (11) for each deformable elongate component. According to the invention, said weighting means for applying horizontal tensile forces and said weighting means for applying vertical tensile forces are separate and are set up with independent weighting action in at least one position corresponding to said position, or one of said positions, of use.</p> |
