针对移动式观赏席之使用方法赋予自由度，并且充分地减少设置场地之地板的负荷。在复数层之床台系相互地连动且前后移动在以整体之方式展开呈阶梯状之使用位置与排列于上下方向之收纳位置之间，并且于自使用位置进行后退移动时，自位在后方之床台起而依序地朝向收纳位置移动之移动式观赏席中，在上述使用位置上，使在上述复数层之床台中之使用停止床台，能够后退移动至相对于此床台之上面一层之使用的床台而排列于上下方向为止，并且使在上述使用停止床台之下面一层之使用的床台，在相对于此使用停止床台而于前方错开呈阶梯状之相对位置，于后退方向产生卡合，且随着自上述使用位置开始之在使最上层之床台呈停止之状态下之最下层之床台的后退移动，藉由位在上述收纳位置之上述上面一层之使用的床台，而将上述下面一层之使用的床台与上述使用停止床台之间之上述后退方向的卡合加以解除。;[SOLUTION] In movable stands wherein plural stepped floor stands are moved backward and forward in tandem with each other between a use position of developing them stepwise in whole and a housing position of aligning them in up and down directions while they are moved from a posteriorly-located floor platform in sequence toward the housing position in the backward movement from the use position, a use-pausing floor platform among the plural stepped floor platforms is movable backward at the use position until this floor platform is aligned in up and down directions with respect to a one-up using floor platform whereas a one-down using floor platform below the use-pausing floor platform is engaged with the use-pausing floor platform in a backward direction at a relative position shifted stepwise in front thereof, and the engagement of the one-down using floor platform with the use-pausing floor platform in the backward direction is released by the one-up using floor platform located in the housing position associated with the backward movement of the lowermost floor platform from the use position at a state of stopping the uppermost floor platform. |
