Visual effect generating device for e.g. shop window display, comprises diaphragm with deformable panels attached to frame

摘要

The device has a diaphragm construction comprising deformable panels (4) located between a frame (1) and at least one drive mechanism. These panels are attached to the frame and cooperate with the mechanism. The frame is formed by a disc containing a round central opening, or by straight frame pieces joined together by coupling pieces. The drive mechanism comprises a ring (3) or endless chains and includes motors. The panels are made from flexible or elastic material and are triangle-shaped.
