Description

本発明は、配線ダクトのカバー装置に係わり、更に詳しくは配線ダクトを備えた家具や什器においてダクト開口部を開閉するカバー装置に関するものである。 The present invention relates to a cover device for a wiring duct, and more particularly to a cover device for opening and closing a duct opening in furniture or furniture provided with a wiring duct.

従来から配線機能を備えた家具や什器は各種提供され、特に天板一部若しくは天板の後端と後幕板間、あるいは前後の天板間にダクト開口部を設け、該ダクト開口部に開閉可能な配線カバーを設けた構造のデスクやテーブルは周知である。 Various furniture and fixtures equipped with a wiring function have been conventionally provided. In particular, a duct opening is provided between a part of the top plate or the rear end of the top plate and the rear curtain plate, or between the front and rear top plates, and the duct opening is provided. Desks and tables with a structure provided with a wiring cover that can be opened and closed are well known.

特許文献１には、前後の天板の間にダクト開口部を設け、該ダクト開口部の中央部に沿って支持部材を設け、該支持部材の両縁部に円弧状側面を有し、アルミニウム等の押出し型材からなる配線カバーの円弧状の外接面を前記円弧状側面に回転可能に外嵌し、配線カバーを水平から略垂直な状態間で回転可能に支持した構造が記載されている。この場合、垂直状態の配線カバーを水平状態に回転させてダクト開口部を閉じる際に、該配線カバーの急回転を抑制し、また水平状態と垂直状態に保持するために、前記円弧状側面に凹部を二箇所設けるとともに、配線カバーの端部に装着したエンドキャップに弾性的な円弧状の外接面を設け、該外接面の先端に前記凹部に係合する凸部を設け、該凸部が円弧状側面に摺接するように構成している。 In Patent Document 1, a duct opening is provided between the front and rear top plates, a support member is provided along the central portion of the duct opening, and both edges of the support member have arcuate side surfaces, such as aluminum. Described is a structure in which an arc-shaped circumscribed surface of a wiring cover made of an extruded material is rotatably fitted onto the arc-shaped side surface, and the wiring cover is rotatably supported between a horizontal state and a substantially vertical state. In this case, when the vertical wiring cover is rotated in the horizontal state to close the duct opening, the arc-shaped side surface is used to suppress the sudden rotation of the wiring cover and to keep the wiring cover in the horizontal state and the vertical state. Two recesses are provided, an elastic arc-shaped circumscribed surface is provided on the end cap attached to the end of the wiring cover, and a convex portion that engages with the recess is provided at the tip of the circumscribed surface. It is configured to be in sliding contact with the arcuate side surface.

また、特許文献２には、ダクト開口部の長手方向に複数に分割した配線カバーを配置し、各配線カバーは押出し型材のカバー本体の両端に端部材を装着した構造であり、各配線カバーの端部材を、ダクト開口部内に配置した端部支承具と中間支承具で回転可能に支持する構造が記載されている。ここで、配線カバーを複数に分割して中間支承具を用いる理由は、デスクの横幅が広くなると配線カバーの撓みが問題になり、また撓まないように剛性を高めると重量が重くなり過ぎるという問題を解消するためである。勿論、配線カバーの重量が重くなると、開閉動作が重くなって使い勝手が悪くなり、また開放状態から閉じる際に、急回転して大きな衝突音が発生することも想定される。 Further, in Patent Document 2, a plurality of wiring covers are arranged in the longitudinal direction of the duct opening, and each wiring cover has a structure in which end members are attached to both ends of a cover body of an extruded mold material. A structure is described in which the end member is rotatably supported by an end support and an intermediate support arranged in the duct opening. Here, the reason why the wiring cover is divided into a plurality of parts and the intermediate bearing is used is that the bending of the wiring cover becomes a problem when the width of the desk is widened, and the weight becomes too heavy when the rigidity is increased so as not to bend. This is to solve the problem. Of course, if the weight of the wiring cover becomes heavy, the opening / closing operation becomes heavy and the usability deteriorates, and it is assumed that when the wiring cover is closed from the open state, it suddenly rotates and a loud collision noise is generated.

特許文献３には、配線カバーの回動部に回転ダンパーを設けた構造が記載されているが、構造が複雑になり部品点数も増える。尚、重量の重い扉や可動部のヒンジ部に回転ダンパーを設けて、回動速度を制限するブレーキ機構を設けた家具や什器は多数存在するが、回転ダンパーは一般的に高価であるため、オフィス家具等に使用するとコスト高となる傾向にある。 Patent Document 3 describes a structure in which a rotating damper is provided in a rotating portion of a wiring cover, but the structure becomes complicated and the number of parts increases. There are many furniture and fixtures that have a rotating damper on a heavy door or a hinge of a movable part to limit the rotation speed, but the rotating damper is generally expensive. When used for office furniture, etc., the cost tends to be high.

そこで、本発明が前述の状況に鑑み、解決しようとするところは、デスクやテーブル、あるいはベンチ等の配線ダクトを備えた家具や什器において、撓みが少なく、剛性が高い配線カバーであってもダクト開口部を回動開閉する操作が軽く、また衝突音の発生を抑制することが可能な配線ダクトのカバー装置を提供する点にある。 Therefore, in view of the above situation, the present invention attempts to solve the problem in furniture and fixtures provided with wiring ducts such as desks, tables, and benches, even if the wiring cover has low bending and high rigidity. The point is to provide a wiring duct cover device capable of lightly rotating and opening and closing the opening and suppressing the generation of collision noise.

The wiring duct cover device according to (4), wherein the lateral movement of the wiring cover is restricted by contacting the edge of the notch with the support base.

以上にしてなる本発明の配線ダクトのカバー装置は、以下に示す効果を奏する。 The wiring duct cover device of the present invention as described above has the following effects.

（１）の構成によれば、軸支部に近い位置にストローク式ダンパーを設けたので、配線カバーを閉じる動作の早い段階からダンパー機能を使用することができ、配線カバーの重量の差異を吸収することができる。また、ストローク式ダンパーの作動ピンと配線カバーの接触音も加速度がかかる前に接触することで低減化を図ることができる。回転ダンパーよりも安価なストローク式ダンパーを用いることで、コストダウンが図れるにも係わらず、回転ダンパーに匹敵する配線カバーの閉止時の静寂性が得られる。更に、閉止状態から配線カバーを持ち上げて開く際に、ストローク式ダンパーの弾性付勢力の支援で軽く開くことができる。更に、ストローク式ダンパーの作動ピンに斜め方向から荷重が加わり難くなるので、軸支部により近い位置にストローク式ダンパーを配置することができる。本来ダンパー本体にかかる斜め荷重を滑らせ逃がす事で下記効果が可能となる。 According to the configuration of (1), since the stroke type damper is provided at a position close to the shaft support, the damper function can be used from an early stage of the operation of closing the wiring cover, and the difference in the weight of the wiring cover is absorbed. be able to. Further, the contact noise between the operating pin of the stroke type damper and the wiring cover can be reduced by contacting the operation pin and the wiring cover before the acceleration is applied. By using a stroke type damper, which is cheaper than a rotary damper, it is possible to obtain quietness when the wiring cover is closed, which is comparable to that of a rotary damper, even though the cost can be reduced. Further, when the wiring cover is lifted and opened from the closed state, it can be opened lightly with the support of the elastic urging force of the stroke type damper. Further, since it is difficult for a load to be applied to the operating pin of the stroke type damper from an oblique direction, the stroke type damper can be arranged at a position closer to the shaft support portion. The following effects can be achieved by sliding and releasing the diagonal load that is originally applied to the damper body.

（２）の構成によれば、ストローク式ダンパーの作動ピンに斜め方向から荷重が加わり難くなるので、軸支部により近い位置にストローク式ダンパーを配置することができる。特に、作動ピンの上端部を半球状の当接部とし、配線カバーの作動ピンの上端部が当接する受面を下に凸の円弧面とすることにより、作動ピンと配線カバー受面との摺動抵抗を大幅に低減することができる。また、ストローク式ダンパーの耐久性を向上させることができる。 According to the configuration of (2), since it is difficult for a load to be applied to the operating pin of the stroke type damper from an oblique direction, the stroke type damper can be arranged at a position closer to the shaft support portion. In particular, the upper end of the working pin is a hemispherical contact portion, and the receiving surface with which the upper end of the working pin of the wiring cover is in contact is a downwardly convex arc surface, so that the sliding between the working pin and the wiring cover receiving surface is formed. The dynamic resistance can be significantly reduced. In addition, the durability of the stroke type damper can be improved.

（３）の構成によれば、配線カバーを閉じ切って水平状態となった際に、作動ピンの当接部は受面の水平面に当接するので、作動ピンには軸方向の力しか作用しなくなり、長時間その姿勢を維持してもストローク式ダンパーに無理な力が加わらない。 According to the configuration of (3), when the wiring cover is completely closed and the wiring cover is in a horizontal state, the contact portion of the working pin comes into contact with the horizontal plane of the receiving surface, so that only an axial force acts on the working pin. Even if the posture is maintained for a long time, no excessive force is applied to the stroke type damper.

（４）の構成によれば、配線カバーが長尺になっても、剛性が高いので撓みを防止でき、また軸支部にガタツキない回動動作が実現できる。配線カバーの軸溝に支承具の支軸を嵌合する際には、スリットの存在で支軸の外径が弾性的に小さくなるので容易になり、また嵌合した後には支軸が元の形状に復元しようとするので、密嵌状態を維持することができる。 According to the configuration of (4), even if the wiring cover is long, the rigidity is high, so that the bending can be prevented, and the rotation operation without rattling of the shaft support can be realized. When fitting the support shaft of the bearing tool into the shaft groove of the wiring cover, it is easy because the outer diameter of the support shaft is elastically reduced due to the presence of the slit, and the support shaft is the original after fitting. Since it tries to restore the shape, the tightly fitted state can be maintained.

（５）の構成によれば、カバー本体の長さを適宜切断して所望の長さの配線カバーを構成でき、また支承具を配置する位置に応じてカバー本体の軸溝に切欠部を形成すれば良く、設計の自由度が高く、また切欠部に支持台を受け入れることにより、配線カバーの横方向の変位を規制することができる。 According to the configuration of (5), the length of the cover body can be appropriately cut to form a wiring cover having a desired length, and a notch is formed in the shaft groove of the cover body according to the position where the support tool is arranged. This is sufficient, the degree of freedom in design is high, and the lateral displacement of the wiring cover can be regulated by accepting the support base in the notch.

FIG. 1 shows bench A as an example of furniture or furniture to which the wiring duct cover device of the present invention is applied, FIGS. 3 is a wiring duct, 4 is a duct opening, 5 is a wiring cover, and 6 is a support tool.

本実施形態のベンチＡは、前後に間隔を置いて天板１，１を脚部２で支持し、前後の天板１，１間にダクト開口部４を設けたものであり、テーブルと基本構成は同じであるが、脚部２の高さが低い設定である。そして、前記ダクト開口部４に前後にそれぞれ配線カバー５，５を配置した構造である。尚、前記配線カバー５は、天板１の横幅の半分の長さに分割して配置している。 In the bench A of the present embodiment, the top plates 1 and 1 are supported by the legs 2 at intervals in the front and rear, and a duct opening 4 is provided between the front and rear top plates 1 and 1. The configuration is the same, but the height of the leg 2 is set to be low. The structure is such that the wiring covers 5 and 5 are arranged in the front and rear of the duct opening 4, respectively. The wiring cover 5 is divided into half the width of the top plate 1 and arranged.

本発明の配線ダクトのカバー装置は、家具や什器の適所に設けたダクト開口部４に、回動開閉可能に配線カバー５を設け、前記ダクト開口部４内に配置した少なくとも二つの支承具６に前記配線カバー５の基端部を軸支部７にて上下回動可能に支持するとともに、前記支承具６の軸支部７の近傍位置にストローク式ダンパー８をその作動ピン９を上向きにして上下方向に配置して、前記配線カバー５が所定角度の傾斜状態から水平状態に至るまで前記作動ピン９が前記配線カバー５の受面１０に当接して、該配線カバー５を開く方向へ弾性付勢することを特徴としている。 In the wiring duct cover device of the present invention, the wiring cover 5 is provided in the duct opening 4 provided at an appropriate position in furniture or furniture so as to be rotatable and openable, and at least two support tools 6 arranged in the duct opening 4 are provided. The base end portion of the wiring cover 5 is supported by the shaft support portion 7 so as to be vertically rotatable, and a stroke type damper 8 is placed in the vicinity of the shaft support portion 7 of the support tool 6 with its operating pin 9 facing up and down. Arranged in the direction, the operating pin 9 abuts on the receiving surface 10 of the wiring cover 5 from the tilted state to the horizontal state of the wiring cover 5 at a predetermined angle, and is elastically attached in the direction of opening the wiring cover 5. It is characterized by the momentum.

具体的には、図３及び図４に示すように、前記配線カバー５は、カバー本体１１の両端部にキャップ１２を装着した構造であり、前記カバー本体１１はアルミニウムの押出し型材で作成し、所定長さに切断した端部に合成樹脂成形品であるキャップ１２を固定している。ここで、前記受面１０は、前記カバー本体１１の裏面側の全面に形成した下面で構成することも可能であるが、少なくとも前記軸支部７に近い部分に設けた当接片で構成しても良い。また、前記カバー本体１１の基部には、断面略Ｃ字形の軸溝１３を形成するとともに、先端部にはアリ溝１４を形成して、合成樹脂やゴムからなる軟質片１５を装着している。 Specifically, as shown in FIGS. 3 and 4, the wiring cover 5 has a structure in which caps 12 are attached to both ends of the cover main body 11, and the cover main body 11 is made of an extruded aluminum mold material. A cap 12, which is a synthetic resin molded product, is fixed to an end cut to a predetermined length. Here, the receiving surface 10 may be formed of a lower surface formed on the entire surface of the back surface side of the cover main body 11, but may be composed of a contact piece provided at least in a portion close to the shaft support portion 7. Is also good. Further, a shaft groove 13 having a substantially C-shaped cross section is formed at the base of the cover body 11, and a dovetail groove 14 is formed at the tip thereof, and a soft piece 15 made of synthetic resin or rubber is attached. ..

前記支承具６は、合成樹脂の成形品であり、一端部に上方へ突出した支持台１６を設け、該支持台１６に両側端を側方へ突出状態で支軸１７を一体的に設けている。つまり、前記支持台１６と支軸１７とで略Ｔ字形を構成している。また、前記支軸１７には上方へ開口し軸方向に延びたスリット１８を形成し、該支軸１７の外径が弾性的に縮小できるようにしている。更に、前記支承具６には、前記支軸１７の近傍位置に前記ストローク式ダンパー８を上下方向に向けて保持する支持筒１９を一体的に設けるとともに、該支持筒１９から離れた位置に緩衝部材２０を保持している。 The bearing 6 is a molded product of synthetic resin, and a support 16 projecting upward is provided at one end thereof, and a support shaft 17 is integrally provided on the support 16 with both ends projecting sideways. There is. That is, the support base 16 and the support shaft 17 form a substantially T-shape. Further, the support shaft 17 is formed with a slit 18 that opens upward and extends in the axial direction so that the outer diameter of the support shaft 17 can be elastically reduced. Further, the support tool 6 is integrally provided with a support cylinder 19 for holding the stroke type damper 8 in the vertical direction at a position near the support shaft 17, and is buffered at a position away from the support cylinder 19. Holds the member 20.

前記軸支部７は、前記カバー本体１１の断面略Ｃ字形の軸溝１３に、前記支承具６に軸方向を水平に向けて形成したスリット付きの支軸１７が回動可能に密嵌して構成される。ここで、前記カバー本体１１の軸溝１３の一部に前記支承具６の支持台１６を受け入れる切欠部２１を切削にて形成している。そして、前記配線カバー５を垂直状態若しくは先端を前傾させた状態で、前記切欠部２１に支持台１６を受け入れながら、前記支軸１７の両端部を切欠部２１の両側の軸溝１３に嵌入する。前記支軸１７を軸溝１３に嵌入する際に、前記スリット１８の存在で支軸１７の外径を弾性的に縮小するので、比較的容易に嵌入でき、嵌合後には前記支軸１７は元の形状に弾性的に復元するので、軸溝１３に密嵌状態となり、適度な摩擦抵抗力を持って回動可能に配線カバー５が支承具６に支持される。ここで、前記切欠部２１を形成する位置は任意であり、前記支承具６を取付ける位置に応じて決定される。そして、前記支持台１６に切欠部２１の縁部が当接することで前記配線カバー５の横方向移動を規制している。 In the shaft support portion 7, a support shaft 17 having a slit formed in the support tool 6 with the axial direction oriented horizontally is rotatably and tightly fitted into the shaft groove 13 having a substantially C-shaped cross section of the cover main body 11. It is composed. Here, a notch 21 for receiving the support 16 of the bearing 6 is formed by cutting in a part of the shaft groove 13 of the cover main body 11. Then, with the wiring cover 5 in a vertical state or with the tip tilted forward, while accepting the support base 16 in the notch portion 21, both ends of the support shaft 17 are fitted into the shaft grooves 13 on both sides of the notch portion 21. do. When the support shaft 17 is fitted into the shaft groove 13, the outer diameter of the support shaft 17 is elastically reduced by the presence of the slit 18, so that the support shaft 17 can be fitted relatively easily. Since it is elastically restored to its original shape, it is tightly fitted in the shaft groove 13, and the wiring cover 5 is supported by the bearing 6 so as to be rotatable with an appropriate frictional resistance. Here, the position where the notch 21 is formed is arbitrary, and is determined according to the position where the support 6 is attached. Then, the edge portion of the notch portion 21 comes into contact with the support base 16 to regulate the lateral movement of the wiring cover 5.

前記ストローク式ダンパー８は、通常軸方向に荷重をかけて使用するので、回動部材に使用しないが、作動ピン９になるべく軸方向以外の荷重がかからないように、本発明では工夫を施している。その一つは、前記ストローク式ダンパー８を軸支部７の近傍位置に配置することである。その二は、前記ストローク式ダンパー８の作動ピン９の上端部を、半球状の当接部２２とし、前記配線カバー５の前記作動ピン９の上端部が当接する受面１０を、下に凸の円弧面２３としたことである。 Since the stroke type damper 8 is normally used by applying a load in the axial direction, it is not used for a rotating member, but the present invention is devised so that a load other than the axial direction is not applied to the operating pin 9 as much as possible. .. One of them is to arrange the stroke type damper 8 at a position near the shaft support portion 7. The second is that the upper end portion of the actuating pin 9 of the stroke type damper 8 is a hemispherical contact portion 22, and the receiving surface 10 with which the upper end portion of the actuating pin 9 of the wiring cover 5 abuts is convex downward. It is said that the arc surface 23 of the above is used.

本発明において、「軸支部の近傍位置に」とは、軸支部７とストローク式ダンパー８の中心間距離が、前記カバー本体１１の横幅の１／３以内の距離、より好ましくは１／４以内の距離である。 In the present invention, "at a position near the shaft support" means that the distance between the center of the shaft support 7 and the stroke damper 8 is within 1/3, more preferably within 1/4 of the width of the cover body 11. Is the distance.

前記支承具６の支持筒１９の口部には、前記ストローク式ダンパー８を挿入した状態で、上下反転させても脱落しないように摩擦接触部又は係合突出部を設けてあり、また底部には穴２４を設け、前記ストローク式ダンパー８を支持筒１９から外す際に、ドライバー等の工具を穴２４から差し入れることができるようにしている。また、前記配線カバー５の重量が重い場合に、初期の衝撃を緩和するために、前記支持筒１９の底部にゴム製の緩衝体２５を介装している。ここで、前記緩衝体２５は、二枚の円板の間に該円板よりも直径が小さな扁平円柱状のゴム材を挟み込んで積層した構造である。 The mouth of the support cylinder 19 of the support tool 6 is provided with a friction contact portion or an engaging protrusion so that the stroke type damper 8 is not dropped even if it is turned upside down with the stroke damper 8 inserted, and the bottom portion thereof. Is provided with a hole 24 so that a tool such as a screwdriver can be inserted through the hole 24 when the stroke type damper 8 is removed from the support cylinder 19. Further, when the weight of the wiring cover 5 is heavy, a rubber shock absorber 25 is interposed at the bottom of the support cylinder 19 in order to alleviate the initial impact. Here, the shock absorber 25 has a structure in which a flat cylindrical rubber material having a diameter smaller than that of the discs is sandwiched between two discs and laminated.

本実施形態では、前記ダクト開口部４の中央に前記天板１と同じ高さの支持杆２６を脚部２，２間に渡して固定し、前記ダクト開口部４を前後に分割し、そして前記支持杆２６の下面側に交差するように、前後の天板１，１間に渡って保持部材２７を設け、該保持部材２７の上面に前記支承具６を取付けている。 In the present embodiment, a support rod 26 having the same height as the top plate 1 is passed between the legs 2 and 2 and fixed to the center of the duct opening 4, the duct opening 4 is divided into front and rear parts, and the duct opening 4 is divided into front and rear parts. A holding member 27 is provided between the front and rear top plates 1 and 1 so as to intersect the lower surface side of the support rod 26, and the support tool 6 is attached to the upper surface of the holding member 27.

図４は、前記配線カバー５を垂直状態にしてダクト開口部４を全開した状態を示している。ここで、本発明において「垂直」とは、略垂直を含む概念である。図５は、前記配線カバー５を回動させて閉じる途中で、前記ストローク式ダンパー８の作動ピン９の上端部に前記カバー本体１１の受面１０が当接した状態を示している。図６は、前記配線カバー５を水平状態にしてダクト開口部４を全閉した状態を示している。図５の状態から図６の状態まで、前記ストローク式ダンパー８の作動ピン９の半球状の当接部２２が、前記カバー本体１１の受面１０の円弧面２３に摺接しながら、前記配線カバー５の自重による回転モーメントの一部を相殺し、該配線カバー５から手を離してもゆっくりと閉じるようになっている。図６の全閉状態で前記配線カバー５の受面１０は前記緩衝部材２０に当止している。ここで、前記配線カバー５は閉じ切ると水平状態となり、前記作動ピン９の半球状の当接部２２は、配線カバー５を閉じる過程において受面１０の円弧面２３を経て最終的に水平面に当接した状態となる。 FIG. 4 shows a state in which the wiring cover 5 is in a vertical state and the duct opening 4 is fully opened. Here, in the present invention, "vertical" is a concept including substantially vertical. FIG. 5 shows a state in which the receiving surface 10 of the cover main body 11 is in contact with the upper end of the operating pin 9 of the stroke type damper 8 while the wiring cover 5 is being rotated and closed. FIG. 6 shows a state in which the wiring cover 5 is in a horizontal state and the duct opening 4 is fully closed. From the state of FIG. 5 to the state of FIG. 6, the hemispherical contact portion 22 of the operating pin 9 of the stroke type damper 8 is in sliding contact with the arcuate surface 23 of the receiving surface 10 of the cover body 11, and the wiring cover. A part of the rotational moment due to the weight of the wiring cover 5 is offset, and the wiring cover 5 is slowly closed even when the hand is released. In the fully closed state of FIG. 6, the receiving surface 10 of the wiring cover 5 is in contact with the cushioning member 20. Here, when the wiring cover 5 is completely closed, the hemispherical contact portion 22 of the operating pin 9 is finally brought into a horizontal plane through the arc surface 23 of the receiving surface 10 in the process of closing the wiring cover 5. It will be in a state of contact.

尚、前記緩衝部材２０を設ける代わりに、前記支承具６に一体成形した上下方向に弾力性を備えた板バネ部６Ａで前記配線カバー５、具体的にはカバー本体１１の遊端部を当接するようにしても良い。 Instead of providing the cushioning member 20, a leaf spring portion 6A integrally molded with the support tool 6 and having elasticity in the vertical direction is used to hit the wiring cover 5, specifically, the free end portion of the cover body 11. You may make contact.

また、前記配線カバー５を全開状態（垂直状態）に保持するために、あるいはクリック感を持たせるために、前記支承具６の端部に爪片２８を設けるとともに、前記配線カバー５、つまりカバー本体１１の基端に前記爪片２８を係合する凹部２９を設けている。 Further, in order to hold the wiring cover 5 in the fully open state (vertical state) or to give a click feeling, a claw piece 28 is provided at the end of the support tool 6, and the wiring cover 5, that is, a cover. A recess 29 for engaging the claw piece 28 is provided at the base end of the main body 11.

全閉状態の前記配線カバー５を開く場合には、前記ストローク式ダンパー８の作動ピン９が突出方向へ弾性付勢されているので、開く操作が軽くなる。 When the wiring cover 5 in the fully closed state is opened, the operating pin 9 of the stroke type damper 8 is elastically urged in the protruding direction, so that the opening operation becomes lighter.
