Display device for changing advertising, comprises two sets of rotary bodies with their advertising sides connected via non intersecting cables

摘要

The display has at least two sets of rotary bodies that have advertising information on two opposite sides. A body belonging to the second set is suspended underneath a body belonging to the first set by cables secured to the first body. The two advertising sides (A2, B2) of the second body are oriented in the same way as the two advertising sides (A1, B1) on the first body. At least one cable (9) extends between a point (A10) on side A of the first body located above the rotation axis for this body and a point (B2u) on side B of the second body located beneath the rotation axis for this body. This cable follows an S-shaped path with the upper body associated with the upper part of the S and the lower body associated with the lower part of the S. At least one more cable (8, 10) extends between a point (A2u) on side A of the first body located beneath its rotation axis and a point (B10) on side B of the second body located above its rotation axis. ! A third cable is always present, extending between points (A10) and (B2u) or between points (A2u) and (B10). None of these cables intersect with each other. The bodies are rotatable through 180 deg.
