Title:
MOVING STANDS
Document Type and Number:
WIPO Patent Application WO/2015/181871
Kind Code:
A1
Abstract:
[Problem] To increase the freedom with which moving stands can be used, and to sufficiently reduce the load on a floor surface of an installation site. [Solution] Moving stands wherein a plurality of stages of bases move forward and rearward in an interlocking manner between an in-use position wherein the bases expand together into a staircase shape and a stored position wherein the bases are vertically aligned, and wherein, when the bases recede from the in-use position, the bases move toward the stored position in order from the base positioned at the rear. In the in-use position, a not-in-use base from among the plurality of stages of bases can recede so as to be vertically aligned with an in-use base that is one stage above, and an in-use base that is one stage below the not-in-use base engages the not-in-use base in the receding direction in a relative position that is offset toward the front in a staircase shape. As a result of the receding movement of a lowermost base from the in-use position while an uppermost base is stationary, the receding direction engagement of the not-in-use base and the in-use base that is one stage below is released by the in-use base that is one stage above when the in-use base that is one stage above is positioned in the storage position.
