Description

本発明は机において天板の下に設けられる配線ダクトに関し、より具体的には配線ダクトの側端部(ダクトエンドともいう)の形態とその側端部の支持構造に関する。   The present invention relates to a wiring duct provided under a top plate in a desk, and more specifically to a form of a side end (also referred to as a duct end) of the wiring duct and a support structure for the side end.

従来より机の天板下に、机上で使用するパソコン等の配線を収容等するために、当該天板の左右幅(長さ)方向に延びたトレー状断面や大略U字状断面などの断面を有する配線ダクトを設けたものが知られている。   Conventionally, a cross-section such as a tray-like cross section or a generally U-shaped cross section extending in the left-right width (length) direction of the top board to accommodate the wiring of a personal computer or the like used on the desk under the top board of the desk. What provided the wiring duct which has is known.

前記配線ダクトの天板下での支持形態や取付形態は様々であるが、天板の下に引出しや袖キャビネット部、或は、袖ワゴンを有しない机、例えば、天板とその支持脚から成るテーブルやテーブル状の机では、配線ダクトが外側からよく見えるため、見映えが良好になるように配線ダクトやその取付態様を工夫する必要があると考えられる。   There are various support forms and attachment forms under the top plate of the wiring duct, but the drawer or sleeve cabinet part under the top plate, or a desk without a sleeve wagon, for example, the top plate and its support legs In a table or a table-like desk, the wiring duct can be seen from the outside. Therefore, it is considered necessary to devise the wiring duct and its mounting manner so that the appearance is good.

特に、天板下の状態が当該机の側面からよく見える形態の机、例えば、天板が側面から見てロ字状の脚、4本足の脚、コ状脚など、側面が大きく開放された脚で支持されている机では、配線ダクトのダクトエンドの形態やその支持構造を工夫しないと、配線ダクトのダクトエンドやその支持構造が机の側面に露出したように見えてしまい、見映えの上で問題であるのみならず、十分な取付強度を確保する上でも課題がある。   In particular, a desk in a form in which the state under the top board can be seen well from the side of the desk, for example, a square-shaped leg, a four-legged leg, a U-shaped leg, etc. If the desk is supported by a leg, the duct end of the wiring duct and its supporting structure will appear to be exposed on the side of the desk unless the form of the duct end of the wiring duct and its supporting structure are devised. In addition to the above problem, there is a problem in securing sufficient mounting strength.

例えば、ロ字状脚のように側面が大きく開口した脚で支持された天板の下に配設された配線ダクトでは、前記ロ字状脚の天板下に位置する脚の内面側のスペースが、脚がロ字状故に小さく、このため配線ダクトのダクトエンドの形態、或は、配線ダクト自体の断面形状、並びに、当該ダクトエンドを脚の内面に取付ける支持部材に、強度面及び見映えの面から特段の工夫が必要と考えられる。この点は、4本足の脚、コ状側のような側面から見て大きな開放部がある脚についてもほぼ同様である。
しかし乍ら、このような点の工夫をしたと思われる技術は、例えば先行特許文献1,2の中には見当らない。
For example, in the case of a wiring duct disposed under a top plate supported by a leg having a wide side opening like a square leg, the space on the inner surface side of the leg located under the top board of the square leg However, the leg is small due to the square shape, so the strength of the duct end of the wiring duct, or the cross-sectional shape of the wiring duct itself, and the support member for attaching the duct end to the inner surface of the leg, From this aspect, it is thought that special ingenuity is necessary. This point is almost the same for a leg having four legs and a leg having a large open portion when viewed from a side surface such as a U-shaped side.
However, the technology that seems to have devised such a point is not found in, for example, the prior patent documents 1 and 2.

特許第4133239号公報Japanese Patent No. 4133239 特許第4238101号公報Japanese Patent No. 4238101

そこで、本発明は、天板下に設けられた配線ダクトを、取付スペースが少ない脚の内側面であっても、十分な取付強度と良好な見映えを発現できる配線ダクトの支持構造を提供することを、その課題とする。   Therefore, the present invention provides a wiring duct support structure that can exhibit sufficient mounting strength and good appearance even when the wiring duct provided under the top plate is an inner surface of a leg with a small mounting space. This is the issue.

上記課題を解決することを目的としてなされた本発明配線ダクトの構成は、天板の長さ方向両側が脚で支持されると共に前記天板下面に配線ダクトを有する机の前記配線ダクトであって、その配線ダクトは長さ方向の外側端を前記脚の内面近傍であって当該内面に届かない長さに形成すると共に、当該配線ダクトの外側端部を、その外側端部と脚の上部内面側の間に、斜めに架設する取付ブラケットを介在させて前記脚内面側で支持したことを特徴とするものである。 The configuration of the wiring duct of the present invention made for the purpose of solving the above-mentioned problems is the wiring duct of a desk having both sides in the longitudinal direction of the top plate supported by legs and having a wiring duct on the bottom surface of the top plate. The wiring duct is formed so that the outer end in the length direction is in the vicinity of the inner surface of the leg and does not reach the inner surface, and the outer end of the wiring duct is connected to the outer end and the upper inner surface of the leg. A mounting bracket that is installed obliquely is interposed between the sides, and is supported on the inner surface side of the leg.

本発明は、上記構成において、斜めに架設した前記取付ブラケットを前記脚の上部に固定した支持構造を採ることができる。また、配線ダクトは、浅底トレー状の断面形状とすることができ、トレーの材質は、鉄板の曲げ加工物やアルミや合成樹脂の押出材などでよい。 The present invention having the above structure, it is possible to adopt a support structure of said mounting bracket which is laid diagonally and fixed to the top of the leg. The wiring duct may have a shallow tray-like cross-sectional shape, and the material of the tray may be a bent product of an iron plate or an extruded material of aluminum or synthetic resin.

また、天板の両側部を下から支持する脚は、机を側面から見たとき天板下面の空間が見える開口形態を有する脚体で形成し、この脚体は、角パイプや型材で形成することができる。また、脚体において、天板を上面に載架する上部の水平枠材は、他の枠材より小断面の部材で形成することがある。さらに、配線ダクトの中間部は、天板下面に吊下形態で支持することができる。
一方、天板に中間脚がある机の配線ダクトは、その中間脚を経由する2分割タイプとし、当該配線ダクトの分割端部を前記中間脚において支持させることができる。
In addition, the legs that support both sides of the top plate from below are formed with legs that have an opening shape that allows the space on the bottom surface of the top plate to be seen when the desk is viewed from the side, and these legs are formed from square pipes or molds. can do. Further, in the leg body, the upper horizontal frame member on which the top plate is placed on the upper surface may be formed of a member having a smaller cross section than the other frame members. Furthermore, the intermediate part of the wiring duct can be supported in a suspended form on the lower surface of the top plate.
On the other hand, the wiring duct of the desk with the intermediate leg on the top plate can be of a two-divided type via the intermediate leg, and the divided end of the wiring duct can be supported by the intermediate leg.

本発明は、側面が大きく開放されたロ状やコ状等を呈する脚を備えた天板の下に設ける配線ダクトを、その長さをダクトの外側端前記脚の内面近傍であって当該内面に届かない長さに形成して前記天板の下に配設すると共に、該配線ダクトの外側端を前記脚の内面側において支持するため、前記ダクト外側端面と前記脚の内面側上部の間に取付けブラケットを斜めに架設し、当該ブラケットの両端部を前記ダクト側端面と脚内面に固定するようにしたから、脚側に取付スペースが少なくても、強固な取付けを実現できると共に、配線ダクトの側端や取付ブラケットが、机の側面から露出的に見えないから見映えも良好である。 The present invention provides a wiring duct provided under a top plate provided with legs having a round shape or a U-shape with widely open side surfaces, the length of which is in the vicinity of the inner surface of the leg at the outer end of the duct. In order to support the outer end of the wiring duct on the inner surface side of the leg, the outer end surface of the duct and the upper surface on the inner surface side of the leg are formed. Mounting brackets are installed diagonally between them, and both ends of the brackets are fixed to the duct side end surface and the inner surface of the leg. Since the side end of the duct and the mounting bracket are not exposed from the side of the desk, the appearance is good.

次に、本発明の実施の形態例について、図を参照して説明する。
図1〜図5において、1は4枚の天板部材で、ここでは、一例として奥行き方向700mm、左右方向2000mmの矩形の天板部材14枚を、図1,図2に示すように田の字状に配設して、本発明の大形天板1Aを構成している。天板部材1の前記サイズは一例であって本発明では、天板1Aを形成する天板部材1のサイズ、特に長さは種々の長さのものを使うことができる。
Next, embodiments of the present invention will be described with reference to the drawings.
1 to 5, reference numeral 1 denotes four top plate members. Here, as an example, 14 rectangular top plate members having a depth direction of 700 mm and a horizontal direction of 2000 mm are formed as shown in FIGS. 1 and 2. The large top plate 1A according to the present invention is configured in a letter shape. The said size of the top plate member 1 is an example, and in the present invention, the top plate member 1 forming the top plate 1A can be used in various sizes, particularly lengths.

上記4枚の天板部材1は配置に際して突合せ側に、天板1Aの長さ方向(左右方向)に沿って40〜50mm幅の配線出入れ溝2が、天板1Aの長さ方向のセンターに形成されている。   When the four top plate members 1 are arranged, the wiring entry / exit groove 2 having a width of 40 to 50 mm along the length direction (left-right direction) of the top plate 1A is arranged on the abutting side, and the center in the length direction of the top plate 1A. Is formed.

3,4は、上記天板1Aの左右の側端に、当該天板を下から支えるように配設した、この机の側面から見て(又は脚の正面から見て)横長の略ロ字状をなす左,右の脚である。この脚は、一例として角パイプ材をロ字状に組んで形成されているが、上部の水平部材4aには、他の脚構成部材3b,4bよりも小さい断面の角パイプが使用されている(図6参照)。なお、3c、4cは脚3,4の上部に設けた天板部材1の支持ブラケットである。また、脚3,4は、角パイプ材ではなく、アングル材や型材などで形成してもよい。さらに、本発明が適用できる脚3,4の形態は、上記例の略ロ字状の脚のほか、略コ状や倒立した略凹状、或は4本足脚などのように、机を側面から見たとき、天板下面の空間がよく見える開口形態を有するものである。   Reference numerals 3 and 4 are horizontally long and roughly square-shaped when viewed from the side of the desk (or viewed from the front of the legs) disposed on the left and right side edges of the top plate 1A so as to support the top plate from below. These are the left and right legs. As an example, this leg is formed by assembling a square pipe material into a square shape, but the upper horizontal member 4a uses a square pipe having a smaller cross section than the other leg constituting members 3b and 4b. (See FIG. 6). Reference numerals 3c and 4c denote support brackets for the top plate member 1 provided on the upper portions of the legs 3 and 4, respectively. Further, the legs 3 and 4 may be formed of an angle material or a mold material instead of the square pipe material. Further, the legs 3 and 4 to which the present invention can be applied include a substantially U-shaped leg in the above example, a substantially U-shaped or inverted substantially concave shape, or a four-legged leg. When viewed from above, it has an opening configuration in which the space on the lower surface of the top plate can be seen well.

前記天板1Aの下面側であって上記溝2の下方には、図7,図8にその断面形状が例示された浅いトレー状の配線ダクト5が設けられている。5aはこのダクト5の底板に複数個形成した床からの配線導入穴である。このダクト5の支持構造については、後に詳しく述べる。   A shallow tray-like wiring duct 5 whose cross-sectional shape is illustrated in FIGS. 7 and 8 is provided on the lower surface side of the top plate 1A and below the groove 2. Reference numeral 5 a denotes a wiring introduction hole from the floor formed in plural on the bottom plate of the duct 5. The support structure of the duct 5 will be described in detail later.

6は上記天板1Aの略中心、換言すれば、4枚の天板部材1の各隅部4点が集合する位置の下に配置した中間脚で、ここでは、前記ダクト5の幅とほぼ同じ一辺長を有する断面外形が略コ状をなす部材を、天板1Aの奥行き方向において向い合せ配置することにより、左右面が開放された縦長の開口部6aに形成される一方、前後面に、左右の天板部材1,1の突合せ部を下から支えるために突出した中間腕6b,6cを備えて形成されている。   6 is an intermediate leg disposed under the approximate center of the top plate 1A, in other words, at the position where the four corners of the four top plate members 1 are gathered. By arranging the members whose cross-sectional outlines having the same side length are substantially U-shaped in the depth direction of the top plate 1A, the members are formed in the vertically long opening 6a with the left and right sides open, The left and right top plate members 1, 1 are formed with intermediate arms 6 b, 6 c protruding to support the abutting portions from below.

上記の配線ダクト5は、図示した例では左右2本のダクト部材が、夫々の外端部が取付ブラケット7を介して脚3,4の内面側の上端部に固定される一方、夫々の内端部が前記中間脚6の開口部6aにビス等の固定手段で固定され、かつ、夫々の中間部位が帯材による吊り金具8によって天板1Aの下面に吊下支持されている。   In the example shown in the figure, the wiring duct 5 has two left and right duct members whose outer end portions are fixed to the upper end portions on the inner surface side of the legs 3 and 4 via the mounting brackets 7, respectively. The end is fixed to the opening 6a of the intermediate leg 6 by a fixing means such as a screw, and each intermediate portion is suspended and supported on the lower surface of the top plate 1A by a hanging metal fitting 8 made of a band material.

次に、取付ブラケット7について、図6〜図8を参照して説明する。
取付ブラケット7は、下端側の垂直壁部7aと該壁7aから離間した上端側の水平壁部7bとを、背面に傾斜壁7dを有する連結部7cで連結した態様で形成された部材であり、さらに以下の構成を備えたものである。
Next, the mounting bracket 7 will be described with reference to FIGS.
The mounting bracket 7 is a member formed in such a manner that the vertical wall portion 7a on the lower end side and the horizontal wall portion 7b on the upper end side separated from the wall 7a are connected by a connecting portion 7c having an inclined wall 7d on the back surface. Further, the following configuration is provided.

すなわち、垂直壁部7aは、配線ダクト5のエンド立壁5bが当接されてボルトb−1により固定結合される。この垂直壁部7aの下部前面には、当該ダクト5のエンド底壁5cをボルトb−2で結合するためのボルト穴付き舌片部71aが設けられている。   That is, the vertical wall portion 7a is fixedly coupled by the bolt b-1 with the end standing wall 5b of the wiring duct 5 coming into contact therewith. On the lower front surface of the vertical wall portion 7a, a tongue piece portion 71a with a bolt hole for connecting the end bottom wall 5c of the duct 5 with a bolt b-2 is provided.

一方、上方の水平壁部7bは、その下面側に前記傾斜壁7dに一体的に連続する垂直部71bを有していると共に、水平壁部7bはその前方側に天板部材1に下面からボルトb−3で結合される天板結合部72bと、脚4(3)の上位水平部材4a(3a、図に表われない)の上面に上からボルトb−4で結合される水平部材4aの上面(水平面)結合部73bとが形成されている。なお、上記垂直部71bは、水平向きのボルトb−5によって水平部材4aの立面(垂直面)への結合部として機能する。   On the other hand, the upper horizontal wall portion 7b has a vertical portion 71b integrally connected to the inclined wall 7d on the lower surface side thereof, and the horizontal wall portion 7b extends from the lower surface to the top plate member 1 on the front side. The top plate coupling portion 72b coupled with the bolt b-3 and the horizontal member 4a coupled to the upper surface of the upper horizontal member 4a (3a, not shown) of the leg 4 (3) with the bolt b-4 from above. The upper surface (horizontal plane) coupling portion 73b is formed. In addition, the said vertical part 71b functions as a connection part to the standing surface (vertical surface) of the horizontal member 4a with the volt | bolt b-5 of horizontal orientation.

本発明では、取付ブラケット7が上記のように形成されていることにより、外側端部が脚3,4に届かない長さに形成されたトレー状の配線ダクト5の当該外側端部を、このブラケット7に形成した垂直壁部7aと水平壁部7bと両部7aと7bを繋ぐ連結部7cと各部7a,7b,7cに形成したボルトb−1〜b−5を用いる各結合部によって、脚3,4と天板1Aに、そこが狭溢な部位であっても強固に結合することができる。特に、ボルトb−1とボルトb−2、及び、ボルトb−3,b−4とボルトb−5は、それぞれ直交する向きで配線ダクト5の側端と脚4の上部水平部材4a(3a)にこの取付ブラケット7を介して結合されているので、きわめて強固な結合強度を発揮できる。   In the present invention, since the mounting bracket 7 is formed as described above, the outer end portion of the tray-like wiring duct 5 formed so that the outer end portion does not reach the legs 3 and 4 can be The vertical wall portion 7a formed on the bracket 7, the horizontal wall portion 7b, the connecting portion 7c connecting the both portions 7a and 7b, and the connecting portions using the bolts b-1 to b-5 formed on the respective portions 7a, 7b, 7c, Even if it is a narrow part, it can be firmly coupled to the legs 3 and 4 and the top board 1A. In particular, the bolt b-1 and the bolt b-2, and the bolt b-3, b-4 and the bolt b-5 are respectively orthogonal to the side end of the wiring duct 5 and the upper horizontal member 4a (3a of the leg 4). ) Through the mounting bracket 7, it is possible to exhibit extremely strong bond strength.

また、上記取付ブラケット7の連結部7cの背面は、傾斜壁7dに形成されているので、この傾斜壁7dが配線ダクト5の側端面部を視覚的に遮蔽することができ、従って、脚3,4がロ字状の脚であっても、その側方から配線ダクト内が見え難くなり、見映えの面でも好ましい。
以上の説明は、中間脚6を有する天板1Aを備えた机についてのものであるが、本発明は、中間脚6を使用しない天板1Aを用いた机の配線ダクト5についても、上記側と同様に適用することができる。
Further, since the back surface of the connecting portion 7c of the mounting bracket 7 is formed on the inclined wall 7d, the inclined wall 7d can visually shield the side end surface portion of the wiring duct 5, and accordingly, the leg 3 , 4 are leg-shaped legs, it is difficult to see the inside of the wiring duct from the side, which is preferable in terms of appearance.
The above description is for a desk provided with a top board 1A having an intermediate leg 6. However, the present invention also applies to the wiring duct 5 of a desk using the top board 1A that does not use the intermediate leg 6. Can be applied as well.

本発明は以上の通りであるから、側面が大きく開放された形態の脚で支持された大形天板の下に設けられる配線ダクトを、スマートな形態で天板下に設け前記脚に強固に取付けて支持することができる。   Since the present invention is as described above, the wiring duct provided under the large top plate supported by the legs whose side surfaces are largely open is provided under the top plate in a smart form and is firmly attached to the legs. Can be installed and supported.
