Description

本発明は、昇降天板付きデスク装置に係わり、更に詳しくは昇降天板の下面後部に配線ダクトを設けてなる昇降天板付きデスク装置に関するものである。 The present invention relates to a desk device with a lifting top plate, and more particularly to a desk device with a lifting top plate, which is provided with a wiring duct at the rear of the lower surface of the lifting top plate.

従来から、両側に配した脚体を固定脚の内部に可動脚の下部を上下動可能に支持した構造とし、これら固定脚と可動脚との間に駆動機構を設けて該可動脚を昇降可能とし、該可動脚の上端に取付けた天板の高さを調節可能とした昇降天板付きデスク装置は各種提供されている。 Conventionally, the legs arranged on both sides have a structure in which the lower part of the movable leg can be moved up and down inside the fixed leg, and a drive mechanism is provided between the fixed leg and the movable leg so that the movable leg can be raised and lowered. Therefore, various desk devices with an elevating top plate capable of adjusting the height of the top plate attached to the upper end of the movable leg are provided.

例えば、特許文献１には、両側に配した脚体を固定脚の内部に可動脚の下部を上下動可能に支持した構造とし、これら固定脚と可動脚とに関連づけて駆動機構を設けて該可動脚を昇降可能とし、該可動脚の上端に取付けた天板の高さを調節可能とするとともに、両脚体の固定脚の後端面で上端部間に幕板を取付け、前記天板の後縁と幕板の上端部間に配線ダクトが形成された昇降天板付きデスク装置が開示されている。 For example, in Patent Document 1, the legs arranged on both sides have a structure in which the lower part of the movable leg is supported so as to be movable up and down inside the fixed leg, and a drive mechanism is provided in association with the fixed leg and the movable leg. The movable legs can be raised and lowered, the height of the top plate attached to the upper end of the movable legs can be adjusted, and a curtain plate is attached between the upper ends on the rear end faces of the fixed legs of both legs to rear the top plate. A desk device with an elevating top plate in which a wiring duct is formed between an edge and an upper end of a curtain plate is disclosed.

また、特許文献２には、後端部寄りに上下方向に折曲可能なヒンジ部を備える支持基板における前端部上面に係止片を、かつ後端に前後方向に弾性変形可能な閉塞片をそれぞれ上向に立設してなるダクトユニットにおける前記ヒンジ部よりも後方の端部を、天板の後端下面と所要寸法離間して立設された幕板の上端に、前記閉塞片の上端と天板下面とが当接又は近接するように止着するとともに、前記係止片を、天板下方の補強部材に着脱可能として係合したことを特徴とする机等における配線ダクト構造が開示されている。 Further, in Patent Document 2, a locking piece is provided on the upper surface of the front end portion of a support substrate provided with a hinge portion that can be bent in the vertical direction toward the rear end portion, and a closing piece that is elastically deformable in the front-rear direction is provided at the rear end portion. The upper end of the closing piece is placed on the upper end of the duct unit erected upward, behind the hinge portion, on the upper end of the curtain plate erected at a required dimension distance from the lower surface of the rear end of the top plate. Disclosed is a wiring duct structure in a desk or the like, characterized in that the lower surface of the top plate is brought into contact with or close to each other, and the locking piece is detachably engaged with a reinforcing member below the top plate. Has been done.

しかし、特許文献１に記載の配線ダクト装置は、天板の後縁と幕板の上端部間に形成された配線ダクトの下方に。コード受けを固定的に設けたので、配線作業には天板の下に潜り込み、窮屈な姿勢を強いられるので、大変な労力を要する。また、特許文献２に記載の机等における配線ダクト構造は、支持基板の前端部上面における係止片と天板下方の補強部材との係合を外せば、支持基板はヒンジ部を中心として下向に回動、傾斜するので、ケーブル等を机等の前方よりダクト内に容易に収納することができるというものであるが、支持基板が弾性ヒンジ部によって下向きに傾斜するので、該支持基板に重量のあるコード類を載支した場合には、傾斜角度が大きくなって、コード類が配線作業中に落下する恐れもある。 However, the wiring duct device described in Patent Document 1 is located below the wiring duct formed between the trailing edge of the top plate and the upper end of the curtain plate. Since the cord receiver is fixedly provided, the wiring work requires a great deal of labor because it slips under the top plate and is forced into a cramped posture. Further, in the wiring duct structure in a desk or the like described in Patent Document 2, if the engaging piece on the upper surface of the front end portion of the support substrate and the reinforcing member below the top plate are disengaged, the support substrate is lowered centering on the hinge portion. Since it rotates and tilts in the direction, cables and the like can be easily stored in the duct from the front of the desk or the like. However, since the support substrate is tilted downward by the elastic hinge portion, the support substrate can be stored in the support substrate. If heavy cords are mounted, the inclination angle becomes large and the cords may fall during the wiring work.
