BED DEVICE

To provide a bed having various sizes while suppressing a change in a form of support cradles.SOLUTION: A bed device 10 comprises support cradles 12 each of which includes: a cradle body; a first movable member 33 to be rotated around a rotation shaft 22 positioned to be upper than the cradle body; a connected member to which multiple panel members 16 are connected; and connection means for allowing the panel members of different lengths and various forms to be commonly connected to the connected member. The first movable member is connected to the connected member so as to allow the connected member to be lower than the rotation shaft when the connected member is in a horizontal state. The support cradle supports the multiple panel members which mutually have a same length. A dimension and a shape of the panel member when viewed as a cross section orthogonally crossed with a longitudinal direction of the panel member are the same over whole length of the panel member in the longitudinal direction.SELECTED DRAWING: Figure 1 【課題】支持架台の形態の変更を抑えつつ、多様な大きさの寝台を提供する。【解決手段】架台本体と、前記架台本体よりも上方に位置する回動軸２２回りに回動する第１可動部材３３と、複数のパネル部材１６が連結された被連結部材と、長さが異なる様々な形態の前記パネル部材を共通して前記被連結部材に連結可能な連結手段と、を有する支持架台１２を備えた寝台装置１０。第１可動部材は、被連結部材が水平状態のときに、被連結部材が前記回動軸の下方になるように、被連結部材と連結され、支持架台は、互いに長さが同等とされた複数のパネル部材を支持し、パネル部材を同パネル部材の長手方向に直交する断面で見た場合の寸法形状が、パネル部材の前記長手方向の全長にわたって同等である。【選択図】図１
