  • Projector screen equipped with means for applying vertical and horizontal tensile forces
    Patent number: 8120846
    Abstract: A projection screen (1) has a projection surface (2), support elements (4) for supporting the projection surface in the suspended state, elements for exerting vertical traction forces (FV) including elements (5) for weighting the bottom longitudinal edge of the projection surface, and elements for exerting horizontal traction forces (FH) including firstly two deformable elongate elements (9, 10) each connected to one of the lateral edges of the projection surface and secondly elements (11) for weighting each deformable elongate element. According to the invention, the weighting elements for exerting horizontal traction forces and the weighting elements for exerting vertical traction forces are distinct and are mounted to perform independent weighting action in at least one position corresponding to the or one of the utilization positions.
