Abstract
Movable stands include a plurality of floor stands, and a plurality of leg parts. The leg parts include a first stopper that allows the floor stand and the floor stand one step below to move forward in conjunction with each other to a state of being deviated in a stepped form, and a second stopper that allows the floor stands of the set to move forward in conjunction while being aligned in an up and down direction. The movable stands include a mode switching unit that switches the second stopper between a protruded state and a retracted state, and a switching drive unit. In the storage position, a plurality of sets of mode switching units are integrally driven in conjunction with driving of the switching drive unit to switch the plurality of sets of second stoppers between the protruded state and the retracted state.

Movable stands comprising:
- a plurality of floor stands;
- and
- a plurality of leg parts each horizontally supporting the floor stands and movable in a front and back direction, wherein
- the leg parts includes a first stopper engaged with the leg part of the floor stand that is one step below the floor stand supported by the leg part, and that allows the floor stand and the floor stand one step below to move forward in conjunction with each other to a state of being deviated in a stepped form, and
- a second stopper provided on the leg part of a first floor stand of a set of floor stands that includes some of the plurality of floor stands, configured to protrude toward and retracted from the leg parts of the other floor stands of the set, and engaged with the leg parts of the other floor stands to allow the floor stands of the set to move forward in conjunction while being aligned in an up and down direction,
- the movable stands are movable between a storage position where the floor stands are aligned in the up and down direction as a whole and a normal use position where the floor stands are expanded to a stepped form one step at a time or a shortened use position where the set of floor stands is expanded to the stepped form,
- the movable stands include a plurality of sets of the floor stands,
- in each set of floor stands, the leg parts of the first floor stand are provided with a mode switching unit that includes the second stopper and a switching lever that protrudes behind the leg parts of the first floor stand and switches the second stopper between a protruded state and a retracted state,
- the movable stands further include a switching drive unit fixed behind the leg parts of the plurality of floor stands aligned in a left and right direction at the storage position, and
- the switching drive unit is provided with a movable part that is engaged with a plurality of sets of the switching levers in the storage position, and that is configured to integrally drive a plurality of sets of the switching levers in conjunction with the driving of the movable part to switch a plurality of sets of the second stoppers between the protruded state and the retracted state.
