WIRING DUCT DEVICE OF DESK WITH LIFTABLE TOP PLATE

PROBLEM TO BE SOLVED: To provide a wiring duct device of a desk with a liftable top plate having a structure where leg bodies arranged on both sides include movable legs supported so as to moved vertically with respect to fixed legs, capable of changing height of the top plate supported at an upper edge of both movable legs, and facilitating wiring work arranged in a lower face rear part of the top plate in an easy posture.SOLUTION: A predetermined space is arranged between a lower face rear part of a top plate 2 and the top plate, a rear part of a duct cover 5 is attached with a horizontal support shaft 6 so as to allow a front part to be rotated vertically, a front edge of the duct cover is kept in a generally horizontal state with an engagement tool 7 capable of being engaged/disengaged, and an angle formed by a lower face 8 of the top plate and the duct cover is smaller than 90° in an opened state of the duct cover. A restriction part 11 contacting the lower face of the top plate is arranged at a rear edge of the duct cover so as to keep the angle formed by the lower face of the top plate and the duct cover is 45°-70° in the opened state of the duct cover.SELECTED DRAWING: Figure 8 【課題】両側に配した脚体を固定脚に対して可動脚を上下動可能に支持した構造とし、両可動脚の上端で支持した天板の高さを調節可能とする昇降天板付きデスク装置において、天板の下面後部に設けた配線ダクトへの配線作業が楽な姿勢で容易に行なうことが可能な昇降天板付きデスクの配線ダクト装置を提供する。【解決手段】天板２の下面後部に該天板との間に所定の空間を設けてダクトカバー５の後部を水平な支軸６にて前部が上下方向へ回動可能に取付け、ダクトカバーの前端部を係脱可能な係止具７にて略水平状態に保持し、ダクトカバーを開放した状態で天板の下面８とダクトカバーのなす角度が９０°よりも小さな角度に設定した。ダクトカバーを開放した状態で、天板の下面とダクトカバーのなす角度が４５°〜７０°の角度に保持すべく、ダクトカバーの後端に天板下面に当接する規制部１１を設けた。【選択図】 図８
