<p>PROBLEM TO BE SOLVED: To expand an available floor surface while not advancing a floor base of a predetermined intermediate stage to a normal stepwise use position, but stopping it at a position in the midway of advancing to prevent chairs left in a fallen state on the predetermined intermediate stage from being contaminated and make chairs having only seats available.SOLUTION: In a mobile stand, a plurality of stages of floor bases having each different height mutually on which a plurality of chairs are attached or mounted and which have wheels and are movable forward/backward on a floor surface are engaged with each other and are advanced and retreated between a use position where the floor bases are displaced stepwise from each other and a standby position where the floor bases are vertically aligned with each other. The mobile stand is equipped with an intermediate stage stopping device fixed to the floor surface, which engages with the floor base of a predetermined intermediate stage to keep the floor base stopped with respect to the floor surface in a state that the floor base of the predetermined intermediate stage among the plurality of stages of floor bases advances by a distance shorter than a distance to the stepwise use position with respect to a floor base above the floor base of the predetermined intermediate stage.</p> |
