Advertising chest contg. freely suspended boxes - moved by endless chain and following hexagonal paths on box guide rails

摘要

The chest (1) with viewing windows (3A,3B) and contg. freely suspended moving boxes (4) may be used for filling or advertisement purposes. The boxes (4) remain vertical throughout a hexagonal trajectory, and are displaced by a motor with belt to endless chain (5A) and pinion (6) transmission. The unit now inc. a box guidage system obviating box oscillation due to unbalanced loading. The guidage system comprises hexagonally segmental tracks (20A,20B) which are followed by box-mounted rollers (23a,25a). The tracks (20A,20B) define a relatively light passage on the box (4) trajectory and contg. the rollers (23a,25ae in directions perpendicular to the trajectory. The chest may inc. further stabilizers in the form of spring-loaded deforming parallelograms (30A,30B), locating at the top and bottom of the chest (1), and with rollers (31) contacting the face of a passing caisson (4).
