Kind Code:
A
Abstract:
PURPOSE: To provide a structure which enables the cleaning of seats of stadiums, theaters and the like automatically.
CONSTITUTION: A floor surface of seats has a double structure of a stair-shaped tread floor 3, a bottom flow (not illustrated) which is provided beneath the tread floor 3 to let dust off. As a rope 23 moves in the direction of the arrow as viewed in the drawing, a link section 34 pulls the tread floor 3 to be turned on a fulcrum 7. Thus, dust slides over the tread floor 3, eventually down to a bottom floor therebelow. The dust coming off is collected by a collection means (not illustrated).
