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。   Conventionally, various furniture and fixtures with a wiring function are provided. In particular, a duct opening is provided between the top plate part or the rear end of the top plate and the rear curtain plate, or between the front and back top plates, A desk and a table having 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 front and rear top plates, a support member is provided along the center of the duct opening, arc-shaped side surfaces are provided at both edges of the support member, and the like An arc-shaped circumscribed surface of a wiring cover made of an extrusion type material is rotatably fitted on the side surface of the circular arc, and a structure in which the wiring cover is rotatably supported between horizontal and substantially vertical states is described. In this case, when the wiring cover in the vertical state is rotated in the horizontal state to close the duct opening, in order to suppress the rapid rotation of the wiring cover and to hold the wiring cover in the horizontal state and in the vertical state, While providing two recesses, an end cap mounted on the end of the wiring cover is provided with an elastic arc-shaped circumscribed surface, and a tip of the circumscribed surface is provided with a convex that engages with the concave, and the convex is 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 wiring cover divided into a plurality of pieces in the longitudinal direction of the duct opening is disposed, and each wiring cover has a structure in which end members are attached to both ends of a cover body of an extrusion molded material. An arrangement is described in which the end member is rotatably supported by an end bearing located in the duct opening and an intermediate bearing. Here, the reason for dividing the wiring cover into multiple parts and using an intermediate bearing means that the bending of the wiring cover becomes a problem when the width of the desk becomes wider, and the weight becomes too heavy if the rigidity is increased so as not to bend. It is to solve the problem. Of course, if the weight of the wiring cover is heavy, the opening and closing operation will be heavy and the usability will be poor, and it may be assumed that when it is closed from the open state, it will be rapidly rotated to generate a loud collision sound.

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。   Although the structure which provided the rotation damper in the rotation part of the wiring cover is described in patent document 3, a structure becomes complicated and the number of parts also increases. There are many furniture and fixtures provided with a rotary damper on the heavy door or hinge of the movable part and a brake mechanism to limit the rotation speed, but since the rotary damper is generally expensive, It tends to be expensive when used for office furniture etc.

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-mentioned situation, the present invention intends to solve the problem in furniture or furniture provided with a wiring duct such as a desk, a table, or a bench, even if the wiring cover has a small deflection and a high rigidity. An object of the present invention is to provide a cover device of a wiring duct which is light in operation of opening and closing the opening and which can suppress the generation of collision noise.

When the wiring cover is completely closed, the cover is in a horizontal state, and the contact portion of the operation pin is in contact with the horizontal surface of the receiving surface.

（４）
前記配線カバーのカバー本体はアルミニウムの押出し型材で作成し、前記支承具が合成樹脂の成形品であり、前記軸支部は、前記カバー本体の基部に形成した断面略Ｃ字形の軸溝に、前記支承部に軸方向を水平に向けて形成したスリット付きの支軸を回転可能に密嵌した構造である（１）〜（３）何れか１に記載の配線ダクトのカバー装置。 (4)

The support shaft of the bearing is provided with a lateral end projecting laterally on a support base projecting upward from the support, and a notch for receiving the support base is provided in a part of the axial groove of the cover main body The cover device for the wiring duct according to (4), wherein lateral movement of the wiring cover is restricted by abutting the edge of the notch on 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 above-described wiring duct cover apparatus of the present invention 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 pivot portion, the damper function can be used from the early stage of the operation of closing the wiring cover, and the weight difference of the wiring cover is absorbed. be able to. Further, the contact noise between the operation pin of the stroke type damper and the wiring cover can be reduced by contacting before the acceleration is applied. By using a stroke type damper which is cheaper than the rotary damper, the quietness at the time of closing of the wiring cover comparable to the rotary damper can be obtained although the cost can be reduced. Further, when the wiring cover is lifted and opened from the closed state, it can be lightly opened with the aid of the elastic biasing force of the stroke type damper. Furthermore, since it becomes difficult to apply a load to the actuating pin of the stroke type damper from an oblique direction, the stroke type damper can be disposed at a position closer to the shaft support portion. By sliding off the diagonal load originally applied to the damper body, the following effects are possible.

（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 becomes difficult to apply a load to the actuating pin of the stroke type damper from an oblique direction, the stroke type damper can be disposed at a position closer to the shaft support portion. In particular, the upper end portion of the operating pin is a hemispherical contact portion, and the receiving surface with which the upper end portion of the operating pin of the wiring cover abuts is a downwardly convex circular arc surface. 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 closed and in the horizontal state, the contact portion of the actuating pin abuts against the horizontal surface of the receiving surface, so only an axial force acts on the actuating pin. It will disappear, and no excessive force will be applied to the stroke type damper even if the posture is maintained for a long time.

（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, since the rigidity is high, it is possible to prevent the deflection and to realize the rotation operation without rattling at the support portion. When the support shaft of the bearing is fitted into the shaft groove of the wiring cover, the outer diameter of the support shaft is elastically reduced by the presence of the slit, which becomes easy, and after the connection, the support shaft is the original As it tries to restore the shape, the close fit 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 main body can be appropriately cut to form a wiring cover having a desired length, and a notch can be formed in the axial groove of the cover main body according to the position where the support is arranged. The degree of freedom of design is high, and the lateral displacement of the wiring cover can be restricted by receiving the support at the notch.

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。   The bench A of this embodiment supports the tops 1 and 1 with the legs 2 at intervals in the front and back, and the duct opening 4 is provided between the top and the top 1 and 1 on the table. Although the configuration is the same, the height of the leg 2 is set low. The wiring covers 5 and 5 are disposed at 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 disposed.

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。   The cover device of the wiring duct of the present invention is provided with the wiring cover 5 so as to be able to turn and open and close at the duct opening 4 provided at an appropriate place of furniture and furniture, and at least two supporting members 6 arranged in the duct opening 4 The base end portion of the wiring cover 5 is vertically rotatably supported by the shaft support portion 7, and the stroke type damper 8 is vertically moved to a position near the shaft support portion 7 of the support 6 with the operation pin 9 facing upward. The operation pin 9 contacts the receiving surface 10 of the wiring cover 5 until the wiring cover 5 reaches a horizontal state from the inclined state at a predetermined angle, and the wiring cover 5 is resiliently opened. It is characterized by turning.

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 the caps 12 are attached to both ends of the cover main body 11, and the cover main body 11 is made of an aluminum extrusion material. A cap 12 which is a synthetic resin molded product is fixed to an end cut into a predetermined length. Here, although the receiving surface 10 may be configured by the lower surface formed on the entire surface of the back surface of the cover main body 11, it is configured by the contact piece provided at least in the portion near the pivot 7 Also good. Further, an axial groove 13 having a substantially C-shaped cross section is formed at the base of the cover main body 11, and a dovetail groove 14 is formed at the end, and a soft piece 15 made of synthetic resin or rubber is mounted. .

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 supporting tool 6 is a molded product of synthetic resin, and a support base 16 projecting upward is provided at one end, and a support shaft 17 is integrally provided on the support base 16 with both side ends projecting laterally. There is. That is, the support 16 and the support shaft 17 constitute a substantially T-shape. Further, the support shaft 17 is formed with a slit 18 which opens upward and extends in the axial direction so that the outer diameter of the support shaft 17 can be elastically reduced. Furthermore, a support cylinder 19 for integrally holding the stroke type damper 8 in the vertical direction is provided in the vicinity of the support shaft 17 integrally with the support 6, and buffer is provided at a position away from the support cylinder 19. The member 20 is held.

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 7, a slitted support shaft 17 formed so that the axial direction is horizontally oriented in the support tool 6 is closely fitted in the shaft groove 13 of the C-shaped cross section of the cover main body 11 rotatably. Configured Here, a notch 21 for receiving the support 16 of the bearing 6 is formed by cutting in a part of the axial groove 13 of the cover main body 11. Then, with the wiring cover 5 in a vertical state or in a state in which the tip is inclined forward, both ends of the support shaft 17 are fitted in the axial grooves 13 on both sides of the notch 21 while receiving the support base 16 in the notch 21. Do. When fitting the support shaft 17 into the shaft groove 13, the outer diameter of the support shaft 17 is elastically reduced due to the presence of the slits 18, so that the support shaft 17 can be fitted relatively easily. Since the original shape is elastically restored, the wiring cover 5 is supported by the support 6 so as to be in a closely fitted state in the axial groove 13 and 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 bearing 6 is attached. Then, the edge of the notch 21 abuts on the support base 16 to restrict 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。   The above-mentioned stroke type damper 8 is not used as a pivoting member since a load is usually applied in the axial direction, but in the present invention, the device is devised so that no load other than the axial direction is applied to the operating pin 9 . One of them is to dispose the stroke type damper 8 in the vicinity of the shaft support 7. In the second case, the upper end portion of the actuating pin 9 of the stroke type damper 8 is a hemispherical abutment 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 downwardly projected. The arc surface 23 of the

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, “in the vicinity of the bearing portion” means that the distance between the center of the bearing portion 7 and the stroke type damper 8 is within 1/3 of the width of the cover main body 11, more preferably within 1/4. 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 opening of the support cylinder 19 of the support 6 is provided with a frictional contact portion or an engagement protrusion so that it does not fall off even if the stroke type damper 8 is inserted while being flipped up and down. A hole 24 is provided so that a tool such as a driver can be inserted from 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 reduce an initial impact. Here, the buffer body 25 has a structure in which a flat cylindrical rubber material having a diameter smaller than that of the circular plate is sandwiched and laminated between two circular plates.

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 at the center of the duct opening 4 to divide the duct opening 4 back and forth, 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 bearing 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 the state in which the duct opening 4 is fully opened with the wiring cover 5 in the vertical state. 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 abuts on the upper end portion of the actuating pin 9 of the stroke type damper 8 in the middle of rotating and closing the wiring cover 5. 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, while the semispherical contact portion 22 of the actuating pin 9 of the stroke type damper 8 is in sliding contact with the arc surface 23 of the receiving surface 10 of the cover main body 11, the wiring cover A part of the rotational moment due to the weight of 5 is offset, and the wiring cover 5 is slowly closed even if the hand is released. The receiving surface 10 of the wiring cover 5 is in contact with the buffer member 20 in the fully closed state of FIG. Here, when the wiring cover 5 is completely closed, it becomes horizontal, and the hemispherical contact portion 22 of the operating pin 9 passes through the arc surface 23 of the receiving surface 10 in the process of closing the wiring cover 5 and finally becomes horizontal. It will be in the 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。   It should be noted that instead of providing the buffer member 20, the free end portion of the wiring cover 5, specifically the cover main body 11, is pressed by a plate spring portion 6A having elasticity in the vertical direction integrally molded with the support 6. You may touch it.

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 a fully open state (vertical state) or to give a click feeling, claw pieces 28 are provided at the end of the bearing 6, and the wiring cover 5, that is, the cover The base end of the main body 11 is provided with a recess 29 for engaging the claws 28.

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 operation pin 9 of the stroke type damper 8 is elastically biased in the projecting direction, so the opening operation becomes lighter.
