DEFINITION

Classification: 472/29

Having carrier rotating about vertical axis (e.g., merry-go-round, etc.):

(under subclass 1) Subject matter wherein the circuitous path apparatus includes person or object bearing structure turning completely around an upright, i.e., vertical, axial region.

(1) Note. The vertical axis must remain vertical during routine operation of the roundabout. An axis which changes its angular position with respect to vertical and merely passes through a vertical position is, therefore, excluded. An angular transition to or from a loading or unloading position is permitted provided the roundabout turns about a vertical axis thereafter.

47, for a roundabout having a carrier rotating about an axis having a changing position with respect to vertical during routine operation.
