Description

【０００１】
【発明の属する技術分野】
本発明は、オフィスの事務室や会議室等において使用される連結式デスクに関する。
【０００２】
【従来の技術】
上記のようなオフィス用の連結式デスクは、オフィスの事務室や会議室の広さ、使用人数等に応じて所望の天板面積を有するデスクが得られ、また最近ではデスクを使用人数や業務内容に応じて任意に区画して使用する形態（ノンアドレス方式）が多くみられるようになっている。
【０００３】
ところで上記の連結式デスクとしては、従来特公平１−１２４８６号公報（公知例１）、特開平８−１８７１２８号公報（公知例２）に記載のものが知られている。
【０００４】
上記公知例１に記載のものは、長い連結式デスクとする場合、前後方向中央部の梁部材を一方の端部脚に取付けて順次梁部材を連結し、次いで前後の天板を側面板により連結した連結天板を端部脚側から順次梁部材に載架し、最後に他方の端部脚を梁部材と連結天板とに連結する構造であり、各連結天板の目地（継ぎ目）合わせは、一方側の端部に突設されたノックピンを他方側の端部に形成された穴に挿入することにより接続され、天板の前端側には強度部材として連結棒が挿通されていてナットで連結するようになされている。
【０００５】
しかして上記公知例１の構造では、組立て手順として一方の端部から順に組立てて行くため、梁部材を支持しておくための仮台が必要であるほか、前後の天板を梁部材に載架する前に前後の天板同士を側面板により連結する作業が必要であり、しかもその状態で天板を梁部材上に載架するため前記仮台に支持された梁部材に非常に大きな荷重が掛ることになる。
【０００６】
そのため梁部材には必要以上の強度を持たせることが必要となり、また梁部材に載架する前は天板同士は側面板のみにより結合されているだけであるため、これを梁部材上に載架する際に天板や側面板が変形しやすく、この部分にも必要以上の強度を持たせておくことが必要となる。
【０００７】
このように各部材に必要以上の強度を与えておくことが必要であることから必要以上にコストが掛るという問題がある。また梁部材に天板を載架する際には、天板は予め連結されているため重量が大きく、載架作業も容易でない。
【０００８】
このようなことから上記のような問題点を解決するものとして公知例２が提案されている。この公知例２に示されるものは、自立可能な枠体上に天板受を固定し、この天板受上に天板を固定してデスクユニットとし、このデスクユニットの一方の端部に端部脚を設け、他方の端部に別のデスクユニットを順次固定して連結して行き、最後に他方の端部脚を固定するようになされている。そして各デスクユニットの天板の目地合わせは前述の公知例１と同様にノックピンと穴との嵌合によってなされ、また天板の前端側には強度部材として連結棒が挿通されてナットで連結するようになされている。
【０００９】
【発明が解決しようとする課題】
しかるに上記公知例２によるものでは、デスクユニットを自立可能な構成とすることが必要であるため、安定的に自立させるには枠体の奥行きと天板の奥行きとの間に制限を受けることが生じる。すなわち広い天板面を得るために天板の奥行きを広げようとすると、必然的に枠体の奥行きも広げなければならなくなり、連結式デスクの様々な使用の仕方に対応させるために様々な奥行きのサイズの連結デスクを製造しようとするときには天板の奥行きに合わせて様々なサイズの枠体を揃えておく必要があり、その結果、部品の種類が増え、在庫面においても不利であり、結果的にコスト高になるという問題点がある。
【００１０】
また組立てにおいても、デスクユニットを順次横方向に連結するものであるため、どうしても枠体と天板受板と天板との組合わせからなるデスクユニットを移動させなければならず、作業者にかかる負担が非常に大きくなり、加えて隣り合う天板は、各枠体状のデスクユニットに載置されるため各ユニットのレベルを厳密に合わせることが必要となる。
【００１１】
さらに前記公知例１、２に共通して指摘される点として、隣り合う天板の目地合わせはノックピンと穴との嵌合により行なわせているので、目地部の一方の天板側に大きな荷重が加わるとノックピンが嵌合している穴やノックピンが変形し、これに起因して目地部に段差を生じやすく、またその修復は容易でないなどの問題点があった。
【００１２】
【課題を解決するための手段】
本発明は上記従来の技術が有する種々の問題点を解決することを課題としてなされたもので、組立て作業が簡単で作業者の負担を軽減し、少ない部品により低コストの連結式デスクを得ることができるようにし、さらに様々な天板サイズのデスクの展開を可能としながら天板間の目地部分に段差を生じにくくし、加えて段差が生じた場合であってもその修復を簡単に行なえるようにした連結式デスクを提供するものである。
【００１３】
上記課題を解決するため本発明は、端部脚と、中間脚と、前記端部脚またはこれに隣接する中間脚の上部に固定される端部用天板受と、前記各天板受間に隣り合うように載置される一組の天板と、前記各天板の前部側でその長手方向に貫通可能な長さを有し、端部にネジ部が形成された連結棒と、中間に位置する中間脚の上部に固定され、隣接する天板の目地部同士を密着させて保持する中間用天板受と、を備え、前記連結棒の端部と目地部が交差する部位の天板下面に該天板を貫通する前記連結棒の端部が突出し連結用ナットでの連結操作を可能とする連結用凹所を区画するとともに、各天板の目地部にそった端部下面には、前記端部用天板受、中間用天板受が係合する係合段部を目地部にそって前記連結用凹所に至るまで形成し、この凹所内で相隣り合う天板の連結棒のネジ部に連結用ナットを螺合して連結棒同士を連結自在とするとともに、連結棒の外端のネジ部に端部用ナットを螺合して緊締自在とし、前記端部脚とそれに隣接する中間脚とを連結したのち中間に位置する中間脚および反対端の端部脚を連結し、その上に各天板受を取付けてその間に天板を載置し、前記連結棒の外端を端部用ナットで緊締するとともに各天板の目地部下面の連結用凹所内において連結棒端を連結用ナットで牽引して組立てるようにしたことを特徴とする。
【００１４】
前記中間脚間の側面間をフレームで連結し、その側面を側板で閉鎖して該側板間の内部を通線用ダクトすることによりＯＡ機器対応型の連結デスクとすることができる。
【００１５】
また、前記係合段部内部において前記天板受と天板との間に高さ調整用間隔部を形成し、この間隔部内に調整用ナットを不回転として挿入し、前記天板受の下面側から挿入する高さ調整ネジを前記ナットに螺挿して該ネジのネジ込み量に応じ天板の目地部上面の高さ位置を微調整自在とすることにより、連結後における天板の目地部に生じる段差をなくするように調整することができる。
【００１６】
さらに前記天板の目地部下面に形成されている前記連結用凹所に整合する大きさを有し前記凹所内に露出する連結棒に係着される係止具を設ければ連結用凹所やその内部の連結用ナットを隠し、体裁を整えることができる。
【００１７】
また前記端部用天板受を角パイプを主体としてその一側面下端から側方に延びる受板を有する構成とし、中間用天板受は、角パイプを主体としその左右両側面下端から延びる左右の受板を有する構成とすることにより、天板の奥行きが大きい場合であっても撓むことなく支持することができ、特に天板の目地部分に段差を生じることが防がれる。
【００１８】
【発明の実施の形態】
以下、本発明を図面に示す実施の形態を参照して説明する。
【００１９】
図１〜図４は本発明による連結式デスクの一実施形態を組立て順として示す分解斜視図である。
【００２０】
ここに示す連結式デスクの脚としては、連結後において両端に位置する端部脚１，１と、これら端部脚１，１間に位置する中間脚２，２…とを有し、端部脚１はデスクを安定よく支持するため連結式デスクの奥行き幅と略同長の接地用下脚部１ａと上部脚１ｂとが面板１ｃの上下端に有する形態とされ、下脚部１ａの下面両端位置には高さ調整用のアジャスタ３，３が設けられている。
【００２１】
中間脚２は、図１〜図４に示す実施形態では図２にみられるように横長矩形状の一対のフレーム４，４の端部にビス等により固定され、上記フレーム４，４の外面側には側板５，５が取り付けられて前記端部脚１の面板１ｃの窓孔１ｄおよび中間脚２の窓孔２ａを通じ前記フレーム４，４間の空間部にケーブル等を通す通線用のケーブルダクト体６とされている。この中間脚２の下端にもアジャスタ７，７が設けられている。
【００２２】
前記端部脚１にそっておかれる中間脚２の上部には端部用天板受８が、途中に位置する中間脚２の上部には中間用天板受９がそれぞれビス１０により固定される。
【００２３】
上記端部用天板受８は、図８にみられるように角パイプまたはチャンネル状の中空部材１１（図では角パイプを例示）を主体とし、その上面、一側面から側方へ延びる受板１２を有しており、また中間用天板受９は、２本の中空部材１３，１３を主体とし、その上面、側面から左右の側方へ延びる受板１４，１４を有する構成とされている。
【００２４】
天板１５は、その長手方向端部下面が前記端部用天板受８および中間用天板受９の半分に整合するように切り欠かれて係合段部５ａが形成されており、この係合段部５ａの前記天板受８，９の受板１２，１４と対向する面の一部は若干深く切り欠かれていて、その面に当板１６が固着されている。したがってこの部分においては受板１２，１４の上面と天板１５の下面との間に調整用間隔部１７が形成されるようになっている。
【００２５】
前記天板１５の手元側となる前部側にはその長手方向に連結棒１８が若干の遊びをもって挿通されており、この連結棒１８の両端部には雄ネジが刻設されたネジ部１８ａとされている。
【００２６】
上記連結棒１８の端部が位置する部位の天板下面には、図５に示すように連結用凹所１９，１９が形成され、この凹所１９，１９内において互いの天板１５，１５の連結棒１８，１８のネジ部１８ａ，１８ａに連結用ナット２０（長ナット）を螺合して連結するための操作が行なえるようになっている。
【００２７】
連結デスクとなる際の端部に位置する天板１５の外端の連結棒１８のネジ部１８ａには端部用ナット２１が螺合されて該連結棒１８を牽引し、各天板１５，１５…の目地部分が圧着されるようになされている。
【００２８】
前記天板受８，９の受板１２，１４には図６、図７にみられるようにその長手方向にそって長孔２２，２２が形成されており、前記調整用間隔部１７内には矩形状の調整用ナット２３がスライド自在に挿入され、前記長孔２２を通して調整ネジ２４を前記調整用ナット２３のネジ孔に螺挿し、これを締込むことにより調整ネジ２４の先端が当板１６に当ってこれを押し上げ、天板受８，９に対し天板１５の高さ位置を微調整することができるようになされている。この際の天板１５の微少上下動は、連結棒１８が貫通している天板１５の孔の遊びの範囲で行なわれる。
【００２９】
図５（Ｃ）において符号２５は、前記連結用凹所１９，１９に跨がってこれを塞ぐためのカバーで、上記凹所１９，１９に整合する形状の平板材の一面に前記凹所１９，１９内に突出している部分の連結棒１８，１８が嵌合するよう弾性的に拡開自在な一対の爪片２６ａ，２６ａを有する係止具２６，２６と、前記凹所１９，１９の内壁面にそって嵌合するガイド片２７，２７とが設けられ、連結用ナット２０により連結棒１８，１８を連結したのち上記カバー２５を下面側から嵌込んでその係止具２６，２６を連結棒１８，１８に係着させることにより連結用凹所１９，１９の下面の開放面を塞ぐようになされている。
【００３０】
また、図４において２８，２８…は、ケーブルダクト体６の上面を塞ぐ上面カバーで、天板１５，１５の対向端面間に落し込みにより嵌合され、両端にはケーブルダクト体６内のケーブルを引き出すための切欠状のケーブル挿通孔２８ａ，２８ａを有している。
【００３１】
次に上記実施形態の連結式デスクの組立て手順について説明する。
【００３２】
連結式デスクを設置しようとする位置において、まず一端側の端部脚１に中間脚２をボルト３０，３０…で固定し、この中間脚２にフレーム４，４の一端を固定してその他端に中間に位置する中間脚２，２をボルト２９，２９…により連結し、この中間脚２に前記と同様にフレーム４，４、中間脚２、端部脚１の順に取付けて土台部分の組立てを行う。こうしたのち端部に位置する中間脚２，２の上部には端部用天板受８，８を、中間に位置する中間脚２，２の上部には中間用天板受９をそれぞれボルト１０，１０により取付ける。
【００３３】
次いで図３に示すように上記各天板受８，９間に天板１５，１５…をその受板１２，１４上に載置し、これら天板１５，１５の突き合わせ端（目地部）において各天板１５，１５の前部側に挿通する連結棒１８，１８のネジ部１８ａ，１８ａを連結用凹所１９，１９内に突出させ、これらに連結用ナット２０を螺合して相互に連結する。また天板１５，１５の長手方向外端に突出する連結棒１８，１８のネジ部１８ａ，１８ａに端部用ナット２１，２１を螺合して緊締する。これにより天板１５，１５の目地部は密着して連結される。
【００３４】
上記目地部分において、天板１５，１５同士の上面に段差が生じている場合には、調整ネジ２４，２４を調整用ナット２３，２３に螺挿し、これを締込むことにより調整ネジ２４，２４の上端で天板１５，１５を押し上げ、あるいはゆるめることにより天板１５，１５を下げて高さの微調整を行ない、天板１５，１５の上面を面一に揃える。このとき天板１５，１５間に段差を生じている位置に調整用ナット２３をスライドさせ、その位置で調整ネジ２４を螺挿して調整を行うことができる。
【００３５】
なお天板１５，１５の目地部下面の連結用凹所１９，１９にはカバー２５をその係止具２６，２６を連結棒１８，１８に係着して取付けることにより連結用ナット２０が隠されて体裁が整えられる。
【００３６】
図１０は他の実施形態を示す分解図で、この実施形態では一つの中間脚２′の両面にフレーム４，４を取付けるようにし、また端部の中間脚を省略して端部脚１，１にフレーム４，４の他端を直接取付けるようにするとともに端部用天板受８，８は端部脚１，１の上部側面にビス３１，３１により取付けられるもので、他の構成は前述の実施形態と同じである。この実施形態によれば、中間脚の数を少なくすることができ、部品数を少なくすることができる利点がある。
【００３７】
【発明の効果】
以上説明したように本発明によれば、天板を組付けて連結デスクとするとき、最初に中間脚、端部脚、および天板受の所謂連結デスクの土台部分を組立てて仮固定し、その後に天板を載置する構造となるため、組立て時に各部材の最小単位の持ち運びのみですみ、組立て作業を著しく楽に行うことができる。
【００３８】
また広大な天板面を得るために天板の奥行き幅を大きくしても、連結デスクの土台部分を先に組立てるので中間脚間のフレームを含むケーブルダクト体をいたずらに大きくせずとも安定した連結デスクを得ることができ、これにより組立て作業時の安全性の向上を図ることができるばかりでなく、ケーブルダクトとて機能する上記ケーブルダクト体の奥行きの品種も最小単位ですみ、製造上および在庫上も有利であり、延いてはコストの低減を果すことができる。
【００３９】
さらに天板同士を連結する連結棒の端部は天板の目地部下面に形成した連結用凹部内で連結用ナットにより連結するようにしているので、天板下面に余分な突出物が全くなく、下肢空間を十分に確保することができる。
【００４０】
また中間用天板受は、左右に受板を有する構成としているため、天板の目地合わせ部に段差が生じにくく、同一面に配設することが容易にできる。
【００４１】
加えて請求項３のように天板受と天板との間に高さ調整用間隔部を形成し、この間隔部内に調整用ナットを不回転として挿入し、前記天板受の下面側から挿入する高さ調整ネジを前記ナットに螺挿して該ネジのネジ込み量に応じ天板の目地部上面の高さ位置を微調整自在とすれば、仮に天板の組立て後においてその目地部分に段差が生じてもこれを容易に解消することができる。また請求項４によれば、高さ調整位置を長孔の範囲内で任意に選択することができ、一層微調整を図ることができる。
【００４２】
そして前記連結用凹部に請求項５のようなカバーを取付けるようにすれば、凹部が露出しないので体裁をよくすることができ、さらに請求項６のように天板受を角パイプを主体とする構成とすることにより天板受の剛性を増し、天板の奥行き幅を広くとる場合であっても十分に安定支持することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a connected desk used in office offices, conference rooms, and the like.
[0002]
[Prior art]
As for the above-mentioned office desks, a desk with a desired top board area can be obtained according to the size of the office and meeting rooms in the office, the number of people used, etc. There are many forms (non-address system) that can be arbitrarily partitioned according to the contents.
[0003]
By the way, as the above-mentioned connection type desk, those described in Japanese Patent Publication No. 1-12486 (Known Example 1) and JP-A-8-187128 (Known Example 2) are known.
[0004]
In the case of the above-described known example 1, when a long connecting desk is used, the beam member at the center in the front-rear direction is attached to one end leg, and the beam members are sequentially connected. The connected top plate is mounted on the beam member sequentially from the end leg side, and finally the other end leg is connected to the beam member and the connecting top plate. The joint (joint) of each connected top plate Alignment is connected by inserting a dowel pin projecting from one end into a hole formed in the other end, and a connecting rod is inserted as a strength member on the front end of the top plate. It is designed to be connected with a nut.
[0005]
Therefore, in the structure of the above-mentioned known example 1, since the assembly procedure is performed in order from one end, a temporary base for supporting the beam member is necessary, and the front and rear top plates are mounted on the beam member. Before mounting, it is necessary to connect the front and rear top plates with the side plates, and in that state, the top plate is mounted on the beam member, so a very large load is applied to the beam member supported by the temporary table. Will be applied.
[0006]
Therefore, it is necessary to give the beam member strength more than necessary, and since the top plates are connected only by the side plates before mounting on the beam member, this is mounted on the beam member. The top plate and the side plate are easily deformed when erected, and it is necessary to give this part strength more than necessary.
[0007]
Thus, since it is necessary to give each member the intensity | strength more than necessary, there exists a problem that it costs more than necessary. Further, when the top plate is mounted on the beam member, the top plate is connected in advance, so that the weight is large and the mounting work is not easy.
[0008]
For this reason, well-known example 2 has been proposed as a solution to the above problems. In the known example 2, a top plate holder is fixed on a self-supporting frame, and the top plate is fixed on the top plate receiver to form a desk unit. A leg is provided, and another desk unit is sequentially fixed and connected to the other end, and finally the other end leg is fixed. The top plate of each desk unit is jointed by fitting the dowel pin and the hole in the same manner as in the above-mentioned known example 1, and a connecting rod is inserted as a strength member on the front end side of the top plate and connected with a nut. It is made like that.
[0009]
[Problems to be solved by the invention]
However, according to the above-described known example 2, it is necessary to make the desk unit self-supporting, and therefore, there is a restriction between the depth of the frame and the depth of the top plate in order to make the desk unit independent. Arise. In other words, when trying to increase the depth of the top plate to obtain a wide top surface, the depth of the frame must inevitably be increased, and various depths are used to accommodate various ways of using the connected desk. It is necessary to prepare frames of various sizes according to the depth of the top plate, as a result, the number of parts increases, which is disadvantageous in terms of inventory. There is a problem of high cost.
[0010]
In addition, since the desk units are sequentially connected in the horizontal direction during assembly, the desk unit consisting of a combination of the frame, the top plate receiving plate, and the top plate must be moved. The burden becomes very large, and in addition, the adjacent top plates are placed on each frame-like desk unit, so that it is necessary to adjust the levels of each unit strictly.
[0011]
Further, it is pointed out in common with the above-mentioned known examples 1 and 2 that the jointing of the adjacent top plates is performed by fitting the knock pins and the holes, so that a large load is applied to one top plate side of the joint portion. When this occurs, the hole or knock pin into which the knock pin is fitted is deformed, resulting in a problem that a step is likely to occur in the joint portion, and the repair is not easy.
[0012]
[Means for Solving the Problems]
The present invention has been made to solve the above-mentioned various problems of the prior art, and is easy to assemble, reduces the burden on the operator, and obtains a low-cost connected desk with fewer parts. In addition, it is possible to develop desks of various top plate sizes, making it difficult for level differences to occur in the joints between the top plates, and even if there is a level difference, it can be easily repaired. A connected desk is provided.
[0013]
In order to solve the above-mentioned problems, the present invention provides an end leg, an intermediate leg, an end top plate receiver fixed to the upper end of the end leg or an intermediate leg adjacent thereto, and the top plate receivers. A pair of top plates placed adjacent to each other, and a connecting rod having a length that can be penetrated in the longitudinal direction on the front side of each top plate, and having a threaded portion formed at the end portion An intermediate top plate holder that is fixed to the upper portion of the intermediate leg located in the middle and holds the joint portions of the adjacent top plates in close contact with each other, and the end portion of the connecting rod and the joint portion intersect each other The end of the connecting rod penetrating the top plate protrudes from the top of the top plate to define a connection recess that enables connection operation with a connecting nut, and the end along the joint portion of each top plate the lower surface forms the end for top plate receiving, the engagement stepped portion top plate receiving intermediate engages up to the connecting recess along the joints, the concave The connecting nuts are screwed into the threaded portions of the connecting rods of the top plates adjacent to each other so that the connecting rods can be connected together, and the end nuts are screwed into the threaded portions on the outer ends of the connecting rods. After the end legs and the intermediate legs adjacent to the end legs are connected, the intermediate legs located in the middle and the end legs at the opposite ends are connected to each other, and the top plate holders are mounted thereon, and the top plate is interposed therebetween. And tightening the outer end of the connecting rod with an end nut, and pulling the end of the connecting rod in the connecting recess on the lower surface of the joint portion of each top plate. Features.
[0014]
By connecting the side surfaces between the intermediate legs with a frame, closing the side surfaces with side plates, and ducting the inside between the side plates, a connection desk compatible with OA equipment can be obtained.
[0015]
Further, a height adjustment interval portion is formed between the top plate support and the top plate inside the engagement step portion, and an adjustment nut is inserted into the interval portion as non-rotating, and the bottom surface of the top plate support The height adjustment screw inserted from the side is screwed into the nut, and the height position of the top surface of the joint portion of the top plate can be finely adjusted according to the screwing amount of the screw. It is possible to adjust so as to eliminate the level difference generated in the case.
[0016]
Further, if there is provided a locking tool that is sized to match the connecting recess formed on the lower surface of the joint portion of the top plate and that is engaged with the connecting rod exposed in the recess, the connecting recess is provided. And you can hide the connecting nut inside and arrange the appearance.
[0017]
Further, the top plate holder for the end portion is configured to have a receiving plate extending mainly from the lower end of one side surface with a square pipe as a main body, and the intermediate top plate holder is a right and left side extending mainly from the lower end of both left and right side surfaces. With the structure having the receiving plate, even when the depth of the top plate is large, it can be supported without being bent, and in particular, it is possible to prevent a step in the joint portion of the top plate.
[0018]

【The invention's effect】
As described above, according to the present invention, when the top plate is assembled to form a connection desk, first, the intermediate leg, the end leg, and the base portion of the so-called connection desk of the top plate holder are assembled and temporarily fixed, Since the top plate is then placed, it is only necessary to carry the smallest unit of each member when assembling, and the assembling work can be performed remarkably easily.
[0038]
Even if the depth of the top plate is increased in order to obtain a vast top plate surface, the base part of the connecting desk is assembled first, so the cable duct body including the frame between the intermediate legs is not increased unnecessarily and is stable. A connecting desk can be obtained, which not only improves the safety during assembly work, but also the depth of the above-mentioned cable duct body functioning as a cable duct is the smallest unit. This is also advantageous in terms of inventory, and as a result, costs can be reduced.
[0039]
In addition, the end of the connecting rod that connects the top plates to each other is connected by a connecting nut in a connecting recess formed on the bottom surface of the joint of the top plate, so there is no extra protrusion on the bottom surface of the top plate. The leg space can be secured sufficiently.
[0040]
In addition, since the intermediate top plate support has a structure in which the left and right support plates are provided, a step is unlikely to occur at the joint portion of the top plate and can be easily disposed on the same surface.
[0041]
In addition, a height adjustment interval portion is formed between the top plate receiver and the top plate as in claim 3, and an adjustment nut is inserted into the interval portion as a non-rotating portion from the lower surface side of the top plate support. If the height adjustment screw to be inserted is screwed into the nut and the height position of the top surface of the joint portion of the top plate can be finely adjusted according to the screwing amount of the screw, the joint portion of the top plate is temporarily installed after the top plate is assembled. Even if a step occurs, this can be easily eliminated. According to the fourth aspect of the present invention, the height adjustment position can be arbitrarily selected within the range of the long hole, and further fine adjustment can be achieved.
