PROBLEM TO BE SOLVED: To form a multi-purpose space to be as large as possible by reducing a floor area being occupied by a housing cabinet in such a manner that a dental treatment unit is housed as compactly as possible when the dental treatment unit is moved and housed in the housing cabinet after a dental treatment.SOLUTION: An electric turntable 19 is installed on a floor, and at the same time, a dental treatment chair 37 is mounted on the turntable 19. The taking out/putting in of the dental treatment chair 37 to the housing cabinet 1 is facilitated by rotating the turntable 19. Also, the mounted dental treatment chair 37 is constituted to be horizontally rotatable, and the back rest 37a is housed toward the end wall surface side of the housing cabinet 1 at the time of housing. In the meantime, a cuspidor 23 and an assistant hanger 24 are attached to the internal wall surface of an opening/closing door 2 of the housing cabinet 1, and the cuspidor 23 an the assistant hanger 24 are made to be positioned in a space above the seat section 37b of the dental treatment chair 37 when the opening/closing door 3 is closed. Thus, the space is effectively utilized, and the floor area of the housing cabinet 1 for the portion of the floor area being occupied by the cuspidor 23 and the assistant hanger 24 is reduced, and the multi-purpose space is formed to be larger.COPYRIGHT: (C)2009,JPO&INPIT【課題】歯科診療ユニットを診療後に収納キャビネット内に移動して収納する際に、できるだけコンパクトに収納して収納キャビネットの占める床面積を縮小し、多目的空間を少しでも広く形成する。【解決手段】床に電動のターンテーブル19を設けると共にターンテーブル19上に歯科診療椅子37を搭載し、ターンテーブル19を回転することにより収納キャビネット1に対する出し入れを容易にし、かつ搭載した歯科診療椅子37を水平回転可能に構成して、収納時にバックレスト37aを収納キャビネット1の奥壁面側に向けて収納し、一方、収納キャビネット1の開閉扉2内壁面にスピットン23およびアシスタントハンガ24を取り付け、開閉扉3を閉止したときにスピットン23およびアシスタントハンガ24を歯科診療椅子37の座部37b上方の空間に位置させることで、空間を有効利用し、スピットン23およびアシスタントハンガ24が占める床面積分の収納キャビネット1の床面積を削減しして多目的空間を広く形成する。【選択図】図3
