Description

本発明は、対向天板付きデスク装置に係わり、更に詳しくは前後に２つの天板を備え、対面で使用する形態の対向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 facing top plate, and more particularly to a desk device having a facing top plate having two top plates in the front and rear and used in a face-to-face manner.

従来から、左右両側に配置した一対の脚体で、前後に配置した２つの天板が支持され、該天板より下方位置で、左右の前記脚体間に配線ダクトが配置された対向天板付きデスク装置は各種提供されている。代表的には、前後に配置した２つの天板を同じ高さに固定した形態のものがある。あるいは、左右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、これら固定脚と可動脚との間に駆動機構部を設けて該可動脚を昇降駆動し、該可動脚の上端に取付けた天板の高さを調節可能とし、更にそれぞれ独立して昇降可能とした天板を前後に配置して対面で使用可能な昇降天板付きデスク装置も提供されている。 Conventionally, two top plates arranged in the front and rear are supported by a pair of legs arranged on both the left and right sides, and a wiring duct is arranged between the left and right legs at a position below the top plate. Various desk devices with attached desks are provided. Typically, there is a form in which two top plates arranged in the front and rear are fixed at the same height. Alternatively, the legs arranged on both the left and right sides have a structure in which the movable legs can be moved up and down with respect to the fixed legs, and a drive mechanism unit is provided between the fixed legs and the movable legs to drive the movable legs up and down. Also provided is a desk device with an elevating top plate that can be used face-to-face by arranging the top plates attached to the upper ends of the movable legs so that the height of the top plate can be adjusted and that the top plates can be raised and lowered independently. ing.

例えば、特許文献１には、左右両側に配置する一対の脚体の前後端部に伸縮脚をそれぞれ配置し、前側と後側に位置するそれぞれの左右伸縮脚の上端間をビームで連結するとともに、該ビームに前後方向に延びた支持アームを連設し、これらビームと支持アームで天板を支持し、前後の天板がそれぞれ独立して昇降可能とした構造の昇降天板付きデスク装置が記載されている。ここで、前記伸縮脚は、鉛直方向に延びた固定脚と、該固定脚の内部に配置されて昇降可能な可動脚とから構成され、前後の伸縮脚の固定脚の上下端同士を連結杆で連結して側面視四角形状のフレーム脚を構成し、そして前記可動脚の上端に前記ビームを連結している構造となっている。更に、左右両側のベース脚を構成する上側連結杆の前後中央部間には配線ダクトが取付けられているとともに、前後の天板間に位置するパネル板が取付けられている。 For example, in Patent Document 1, telescopic legs are arranged at the front and rear ends of a pair of legs arranged on both the left and right sides, and the upper ends of the left and right telescopic legs located on the front side and the rear side are connected by a beam. A desk device with an elevating top plate has a structure in which support arms extending in the front-rear direction are connected to the beam, the top plate is supported by these beams and the support arm, and the front and rear top plates can be raised and lowered independently. Have been described. Here, the telescopic legs are composed of a fixed leg extending in the vertical direction and a movable leg that is arranged inside the fixed leg and can be raised and lowered, and connects the upper and lower ends of the fixed legs of the front and rear telescopic legs. The beam is connected to the upper end of the movable leg to form a frame leg having a quadrangular side view. Further, a wiring duct is attached between the front and rear center portions of the upper connecting rods constituting the base legs on both the left and right sides, and a panel plate located between the front and rear top plates is attached.

また、特許文献２，３には、各上面に作業面を有し、互いに対向して配置される一対の天板と、前記一対の天板の対向方向と略直交する方向に離間して配置され、前記一対の天板を高さ調整可能に支持する一対の支持構造体と、を備え、前記支持構造体は、床面上に設置されて前記一対の天板の対向する方向に沿って延出するベース部材と、該ベース部材の延出方向の両端位置からそれぞれ上方に向かって立設され、前記一対の天板のそれぞれを高さ調整可能に支持する一対の伸縮脚と、を備えている昇降天板付きデスク装置が記載されている。更に、各前記支持構造体の前記ベース部材の延出方向の略中間位置から上方に立設される支柱部の上部間に、一対の前記天板の間を仕切るパネル板が上方に向かって立設されているとともに、内部に配線収容空間を有する配線ダクトを架設している点も記載されている。 Further, in Patent Documents 2 and 3, a pair of top plates having working surfaces on the upper surfaces thereof and arranged so as to face each other are arranged so as to be separated from each other in a direction substantially orthogonal to the facing direction of the pair of top plates. A pair of support structures that support the pair of top plates in a height-adjustable manner, and the support structures are installed on the floor surface and along the opposite directions of the pair of top plates. It is provided with a base member that extends and a pair of telescopic legs that are erected upward from both ends of the base member in the extension direction and support each of the pair of top plates so that the height can be adjusted. The desk device with the elevating top plate is described. Further, a panel plate for partitioning between the pair of top plates is erected upward between the upper portions of the support columns erected upward from a substantially intermediate position in the extending direction of the base member of each of the support structures. At the same time, it is also described that a wiring duct having a wiring accommodation space is erected inside.

これらの対向天板付きデスク装置において、配線ダクトは前後の天板の中間位置に設けられ、そして複数の対向天板付きデスク装置を平行して設置した場合に、両配線ダクトに渡ってコード類を配線する状況が生じる。そのために、配線ダクトの端部に開閉可能に蓋体を設けることが一般的である。ここで、前記配線ダクトのダクト本体は板金で作製されるが、ダクト本体の端部に取付け、中心に開口を備えたキャップと該キャップに開閉可能に設ける蓋体とは、該蓋体を精度良くスムーズに開閉できるように合成樹脂製とすることが考慮される。しかし、合成樹脂成形品は金型コストが嵩み、小ロット生産には適しない。更に、配線ダクトは床面に近い高さに設置されるので、閉止状態の蓋体を誤って蹴飛ばして破損させる恐れもあり、製造コストと信頼性と耐久性の面で課題がある。 In these desk devices with facing top plates, wiring ducts are provided at intermediate positions between the front and rear top plates, and when a plurality of desk devices with facing top plates are installed in parallel, cords are provided across both wiring ducts. A situation arises in which the wiring is performed. Therefore, it is common to provide a lid that can be opened and closed at the end of the wiring duct. Here, the duct body of the wiring duct is made of sheet metal, but the cap attached to the end of the duct body and having an opening in the center and the lid provided to the cap so as to be openable and closable are accurate. It is considered to be made of synthetic resin so that it can be opened and closed smoothly and well. However, synthetic resin molded products are not suitable for small lot production due to the high mold cost. Further, since the wiring duct is installed at a height close to the floor surface, there is a risk that the closed lid may be accidentally kicked and damaged, which poses problems in terms of manufacturing cost, reliability and durability.

Is to be able to be attached and detached regardless.

前記キャップ５１は、側面視四角形の額縁状部材であり、中央部に開口６４を設け、周縁の縁部６５を前記ダクト本体４８の端部に接合した状態で溶接固定する。前記蓋体５２は、前記キャップ５１の縁部６５の裏面に接合する本体部６６とその表側に重合状態で固定し、前記キャップ５１の開口６４を閉塞する閉塞板６７とからなり、本体部６６の両側下端にアーム６８，６８を折曲形成し、前記キャップ５１の裏面両側の下端部に固定したヒンジ６９，６９に水平な支軸７０，７０によって内向きに回動可能に軸着している。 The cap 51 is a frame-shaped member having a quadrangular side view, and an opening 64 is provided in the central portion, and the peripheral edge portion 65 is welded and fixed in a state of being joined to the end portion of the duct main body 48. The lid 52 is composed of a main body 66 joined to the back surface of the edge 65 of the cap 51 and a closing plate 67 which is fixed to the front side thereof in a polymerized state and closes the opening 64 of the cap 51. Arms 68 and 68 are bent and formed at the lower ends on both sides of the cap 51, and are pivotally attached to hinges 69 and 69 fixed to the lower ends on both sides of the back surface of the cap 51 so as to be rotatable inward by horizontal support shafts 70 and 70. There is.

前記蓋体５２の遊端側に設けた係合部７１には前記係止部材５８の先端部を抱き込み且つ前記当止片５９に当接する切欠部７２を形成し、図１５に示すように、前記係止部材５８の先端部を弾性変形させた際に前記当止片５９が前記蓋体５２の切欠部７２から退避して該蓋体５２が開放可能となる。本発明における係止手段は、先端部が上下に弾性変形する前記係止部材５８と、その先端の当止片５９及び前記蓋体５２の切欠部７２を備えた係合部７１とで構成されている。 A notch 72 that embraces the tip of the locking member 58 and abuts on the retaining piece 59 is formed in the engaging portion 71 provided on the free end side of the lid 52, as shown in FIG. When the tip of the locking member 58 is elastically deformed, the retaining piece 59 retracts from the notch 72 of the lid 52, and the lid 52 can be opened. The locking means in the present invention is composed of the locking member 58 whose tip is elastically deformed up and down, and an engaging portion 71 having a contact piece 59 at the tip and a notch 72 of the lid 52. ing.

更に詳しくは、前記蓋体５２は、板状の本体部６６の上縁を内向きに折曲して、中央部に四角形の切欠部７２を形成した係合部７１を設けている。前記アーム６８，６８と係合部７１は、同じ内側へ延びており、図１６に示すように、前記蓋体５２を内側へ倒伏して開口６４を開放した際に、前記係合部７１の先端が前記ダクト本体４８の底面板５３に当接し、該蓋体５２の上面、即ち閉塞板６７が水平になるように寸法設定されている。 More specifically, the lid 52 is provided with an engaging portion 71 in which the upper edge of the plate-shaped main body 66 is bent inward to form a quadrangular notch 72 at the center. The arms 68, 68 and the engaging portion 71 extend inward in the same manner, and as shown in FIG. 16, when the lid 52 is tilted inward to open the opening 64, the engaging portion 71 of the engaging portion 71. The tip is in contact with the bottom plate 53 of the duct body 48, and the upper surface of the lid 52, that is, the closing plate 67 is sized so as to be horizontal.

前記蓋体５２が閉止状態では、図１５に示すように、前記本体部６６が前記キャップ５１の縁部６５の裏面に当接するとともに、前記閉塞板６７が前記キャップ５１の開口６４を段差無く閉塞し、そして前記係合部７１の切欠部７２内に前記係止部材５８の先端部を抱き込むように係合するとともに、該切欠部７２の底縁が前記当止片５９の外側面に当接し、強固に閉止状態を維持している。そして、前記蓋体５２を開放させるには、前記ダクトカバー５０を取り去り、ダクト本体４８の上方開放部から前記端部固定カバー４９の下方に指を差し入れ、前記係止部材５８の先端部を弾性変形させて押し上げ、前記蓋体５２の切欠部７２から退避させて係合部７１との係合を解除する。その状態で、前記蓋体５２の閉塞板６７を外側から押し込めば、該蓋体５２は簡単に回転して前記底面板５３上に倒伏して開放状態となる。逆に、前記蓋体５２を閉止状態にするには、該蓋体５２を持って立起させるだけで、前記係合部７１が前記係止部材５８の先端部を押し上げながら通過し、先端を通過後には前記係止部材５８が弾性的に復元して前記切欠部７２内に係合するのである。 When the lid 52 is closed, as shown in FIG. 15, the main body 66 comes into contact with the back surface of the edge 65 of the cap 51, and the closing plate 67 closes the opening 64 of the cap 51 without a step. Then, the tip portion of the locking member 58 is engaged so as to be embraced in the notch 72 of the engaging portion 71, and the bottom edge of the notch 72 hits the outer surface of the retaining piece 59. It is in contact and firmly maintained in a closed state. Then, in order to open the lid 52, the duct cover 50 is removed, a finger is inserted below the end fixing cover 49 from the upper opening portion of the duct main body 48, and the tip portion of the locking member 58 is elastically inserted. It is deformed and pushed up, retracted from the notch 72 of the lid 52, and disengaged from the engaging portion 71. In this state, if the closing plate 67 of the lid 52 is pushed in from the outside, the lid 52 easily rotates and falls down on the bottom plate 53 to be in an open state. On the contrary, in order to close the lid 52, simply hold the lid 52 and stand it upright, and the engaging portion 71 passes by pushing up the tip of the locking member 58 and passes through the tip. After passing, the locking member 58 elastically reconstructs and engages in the notch 72.

また、図１３及び図１４に示すように、両脚ユニット４，４間に前記配線ダクト４７を取付けた状態では、前記キャップ５１の端面は前記当止部材２１よりも若干後退した位置、つまり前記当止部材２１は、前記キャップ５１の端面より若干側方へ突出した状態に寸法設定され、側方に昇降天板付きデスク装置を並べて設置した際に、必ず当止部材２１，２１同士が当接するようにしている。 Further, as shown in FIGS. 13 and 14, when the wiring duct 47 is attached between the two leg units 4 and 4, the end surface of the cap 51 is slightly retracted from the retaining member 21, that is, the contact.
