ASSEMBLY TYPE LOFT BED

To provide an assembly type loft bed with which a ladder is stably provided and which can endure repetitive use.SOLUTION: An assembly type loft bed 1 is provided with a bed 2 for an upper step part 1A and a desk 3 for a lower step part 1B, and the upper step part 1A is supported by props 4 standing in four corners. The lower step part 1B is provided at least with: a top plate member 6 functioning as a desk; a first reinforcement frame 7A which is disposed and fixed in a longitudinal direction on the same side as a side frame 2B for a fence; and a second reinforcement frame 8C which is disposed and fixed in a shorthand direction on a rear side orthogonal to the side frame 2B for a fence. The top plate member 6 is disposed in the shorthand direction of the rear end part of the lower step part 1B and is fixed to three members, the first reinforcement frame 7A, the second reinforcement frame 8C and a ladder 5 for moving up and down.SELECTED DRAWING: Figure 1 【課題】ハシゴが安定的に備えられ，繰り返しの使用にも耐えうる組み立て式ロフトベッドを提供する。【解決手段】組み立て式ロフトベッド１は，上段部１Ａに床（とこ）２を，下段部１Ｂに机３を備え，四隅に立設される支柱４によって上段部１Ａが支持される。下段部１Ｂは，机としての機能を果たす天板部材６と，柵用サイドフレーム２Ｂと同じ側の長手方向に配置固定される第一補強フレーム７Ａと，柵用サイドフレーム２Ｂと直交する後側の短手方向に配置固定される第二補強フレーム８Ｃと，を少なくとも備える。そして，天板部材６は，下段部１Ｂの後端部の短手方向に配置されるとともに，第一補強フレーム７Ａ，第二補強フレーム８Ｃ，昇降用ハシゴ５の３つの部材に固定される。【選択図】図１
