Description

本発明は、木質系の組立式机に係わり、更に詳しくは天板の高さが調節可能な木質系の組立式机に関するものである。 The present invention relates to a wooden assembling desk, and more particularly to a wooden assembling desk whose height of a top plate can be adjusted.

従来から天板の高さが調節可能な学習机は各種提供されている。天板の高さ調節機構としては、脚板に内蔵したネジ軸の回転操作に伴い、天板に固定した支持部内に設け前記ネジ軸に螺合したナット部の螺進退によって天板が無段階に昇降するもの、あるいは伸縮構造の両脚板の内部にガスシリンダーを配置して所定伸縮状態で保持するもの、あるいは両脚板間に配した天板両側の支持部を脚板に設けた取付孔を利用してネジ止めし、該取付孔を上下方向に一定間隔で複数設けておき、適当な高さの取付孔を選択して天板を付け替えることによって該天板の高さを調節するものなど様々である。 Various learning desks that can adjust the height of the top have been provided. As the height adjustment mechanism of the top plate, the top plate is steplessly stepped by the screwing back and forth of the nut portion provided in the support part fixed to the top plate and screwed into the screw shaft in accordance with the rotation operation of the screw shaft built in the leg plate. Use the mounting holes provided on the leg plate that support the both sides of the top plate placed between the leg plates, or those that move up and down, or that hold the gas cylinder inside the both legs plate of the telescopic structure A plurality of mounting holes are provided at regular intervals in the vertical direction, and the height of the top plate is adjusted by selecting an appropriate mounting hole and replacing the top plate. is there.

学習机では、製造工場からの搬送、販売店での保管において、スペース効率を考慮して、嵩張らないように板状の部品に分解した状態で梱包し、取り扱うことが多い。その場合、販売店で、又はユーザー宅で簡単に組み立てることができる構造であり、また十分な強度を備えていることは必須である。 The learning desk is often packed and handled in a state of being disassembled into plate-like parts so as not to be bulky in consideration of space efficiency during transportation from the manufacturing factory and storage at the store. In that case, it is essential to have a structure that can be easily assembled at the store or at the user's home and that it has sufficient strength.

机の脚部の構造としては、着席、離席の際に利用者の足の動作を妨げず、また横に複数台並設した際に、隣の机へのアクセスが容易になるという理由で、Ｌ脚構造が好まれる。Ｌ脚は、脚板の奥行幅が天板より狭く、脚板の下端に天板の奥行幅に略等しい接地脚が前方へ延びた構造を有している。このようなＬ脚構造の脚部間に天板を取付ける場合、天板の後部が脚部で支持された片持ち状態となる。金属製の机では天板が片持ち状態でも十分な強度を持たせることができるが、木質系の組立式机では強度不足を解消するには補強構造が必要である。天板の高さが固定的な場合には、脚板に前方へ支持アームを延ばして固定し、該支持アームに天板を取付ければ、強度を保てるが、天板を高さ調節可能に取付ける場合、固定的な支持アームを用いることはできない。また、作業者が一人で組み立てる場合、天板の仮支持がなければ、横に倒した状態で作業しなければならず、手間がかかる。 The structure of the legs of the desk is that it does not interfere with the movement of the user's feet when sitting or leaving, and it is easy to access the next desk when multiple units are installed side by side. The L leg structure is preferred. The L leg has a structure in which the depth of the leg plate is narrower than that of the top plate, and a grounding leg substantially equal to the depth of the top plate extends forward at the lower end of the leg plate. When the top plate is attached between the legs of such an L-leg structure, the rear portion of the top plate is in a cantilever state supported by the legs. A metal desk can provide sufficient strength even when the top plate is cantilevered, but a wooden assembling type desk requires a reinforcing structure to solve the lack of strength. If the height of the top plate is fixed, it is possible to maintain the strength by extending the support arm forward to the leg plate and attaching the top plate to the support arm, but attach the top plate so that the height can be adjusted. In some cases, a fixed support arm cannot be used. Moreover, when an operator assembles alone, if there is no temporary support of a top plate, it will have to work in the state which fell down sideways, and it will take an effort.

特許文献１には、収納キャビネットの両側板間にデスク受け金具を介して前方へ突出するように天板を取付けた構造が開示されている。ここで、デスク受け金具の長さは、側板の奥行幅よりも長く設定され、後部を側板の内面側に形成した前後の取付孔を利用してネジ止め固定し、デスク受け金具の前部は側板より前方へ突出している。前記側板の取付孔は上下方向に所定間隔で複数対設けられており、所定高さのものを選択して前記デスク受け金具を取付け、該デスク受け金具の水平板の上に天板の両側部を載置し、下方から水平板を天板にネジ止めしている。更に、天板の後端は収納キャビネットの背板にアングル状のバック受け金具を用いてネジ止めしている。そして、前記側板より前方に突出したデスク受け金具の側面に化粧用のサイドカバーを取付けている。 Patent Document 1 discloses a structure in which a top plate is attached between both side plates of a storage cabinet so as to protrude forward through a desk bracket. Here, the length of the desk bracket is set longer than the depth of the side plate, and the front portion of the desk bracket is fixed with screws using front and rear mounting holes formed on the inner surface side of the side plate. Projects forward from the side plate. A plurality of pairs of mounting holes in the side plate are provided at predetermined intervals in the vertical direction, and the desk bracket is selected by selecting a predetermined height, and both sides of the top plate are mounted on the horizontal plate of the desk bracket. The horizontal plate is screwed to the top plate from below. Furthermore, the rear end of the top plate is screwed to the back plate of the storage cabinet using an angle-shaped back receiving bracket. And the side cover for makeup | decoration is attached to the side surface of the desk bracket which protruded ahead from the said side plate.

更に詳しくは、図５に示すように、前記Ｌ脚１は、前記脚板７の上下方向に所定間隔毎に前後対となった複数の取付孔１０，１０を貫通形成している。また、前記天板２の両側端下面には支持板１１，１１を固定し、該支持板１１に前記取付孔１０，１０の前後間隔と同じ前後間隔で螺孔１２，１２を形成している。この螺孔１２は、前記支持板１１の内側からオニメナット１３を埋設して設けている。また、前記ブラケット９は、前記脚板７の奥行幅より長く、天板２の奥行幅と同等か短い長さに設定し、後部に前記脚板７の取付孔１０，１０に嵌挿するパイプ状の一対の係合ピン１４，１４を突設するとともに、全長にわたり前記天板２の支持板１１の下面を受ける断面略コ字形の支持レール１５を形成している。そして、前記ブラケット９の係合ピン１４，１４を脚板７の取付孔１０，１０に嵌挿した後、支持レール１５に天板２の支持板１１を載支し、脚板７の外側から前記取付孔１０内の係合ピン１４を貫通させた連結ネジ１６を前記天板２の支持板１１の螺孔１２に螺合する。 More specifically, as shown in FIG. 5, the L leg 1 has a plurality of mounting holes 10, 10 formed in pairs in the vertical direction of the leg plate 7 at predetermined intervals. Further, support plates 11 and 11 are fixed to the lower surfaces of both side ends of the top plate 2, and screw holes 12 and 12 are formed in the support plate 11 at the same front and rear intervals as the front and rear intervals of the mounting holes 10 and 10. . This screw hole 12 is provided with an urine nut 13 embedded from the inside of the support plate 11. Further, the bracket 9 is set to a length longer than the depth width of the leg plate 7 and equal to or shorter than the depth width of the top plate 2, and is a pipe-like shape that is fitted into the mounting holes 10, 10 of the leg plate 7 at the rear part. A pair of engagement pins 14 and 14 are provided so as to project a support rail 15 having a substantially U-shaped cross section for receiving the lower surface of the support plate 11 of the top plate 2 over the entire length. Then, after engaging pins 14, 14 of the bracket 9 are inserted into the mounting holes 10, 10 of the leg plate 7, the support plate 11 of the top plate 2 is mounted on the support rail 15, and the attachment from the outside of the leg plate 7 is performed. A connecting screw 16 through which the engaging pin 14 in the hole 10 passes is screwed into the screw hole 12 of the support plate 11 of the top plate 2.

以下に、各部を更に詳しく説明する。前記天板２は、両側後部に前記脚板７を受け入れる係合部１７を切欠形成し、前記天板２の支持板１１を前記ブラケット９の支持レール１５に載支した状態で、前記係合部１７の前端部を前記脚板７の前端に当接させた状態で、前記螺孔１２，１２と前記取付孔１０，１０の位置が一致するように形成されている。また、図３及び図４に示すように、前記天板２の両側の支持板１１，１１は、該天板２の下面側に設ける引出し１８，１８を収容するボックス体１９の一部を構成している。また、図１、図３及び図５に示すように、前記天板２の係合部１７よりも前方の両側下面に前記ブラケット９を隠蔽する化粧板２０を設け、前記天板２の支持板１１との間に前記ブラケット９の支持レール１５を構成する立上片２１を受け入れる切欠溝２２を前記化粧板２０に設けている。 Hereinafter, each part will be described in more detail. The top plate 2 is formed with cutouts of engaging portions 17 for receiving the leg plates 7 at the rear portions on both sides, and the engaging portion is mounted on the support rails 15 of the bracket 9 with the support plate 11 of the top plate 2 mounted thereon. The screw holes 12, 12 and the mounting holes 10, 10 are formed so that the positions of the screw holes 12, 10 coincide with each other with the front end portion 17 in contact with the front end of the leg plate 7. As shown in FIGS. 3 and 4, the support plates 11, 11 on both sides of the top plate 2 constitute a part of a box body 19 that houses drawers 18, 18 provided on the lower surface side of the top plate 2. doing. As shown in FIGS. 1, 3, and 5, a decorative plate 20 that conceals the bracket 9 is provided on both lower surfaces in front of the engaging portions 17 of the top plate 2, and the support plate for the top plate 2 is provided. 11 is provided with a notch groove 22 for receiving a rising piece 21 constituting the support rail 15 of the bracket 9.

前記ブラケット９は、図５に示すように、後部に垂直な取付板２３を設け、該取付板２３に形成した孔にフランジ付きのパイプからなる前記係合ピン１４を内方から外方へ貫通させ、フランジを取付板２３の内側に溶接し、そして下縁の全長にわたって上方へ開放した断面略コ字形の支持レール１５を折曲形成したものである。前記取付板２３には、前記係合ピン１４のフランジの厚さを受け入れるための凹部を形成し、必然的に他の部分が凸部となるが、凹凸構造により強度を高める効果もある。そして、前記係合ピン１４のパイプは前記取付板２３を貫通しているので、その中心孔２４に前記連結ネジ１６を貫通できるのである。前記支持レール１５を構成する両立上片２１，２１は、前記取付板２３の上下幅よりも小さい高さに設定されている。尚、右用ブラケット９と左用ブラケット９は、鏡像関係にある。そして、前記化粧板２０に形成された切欠溝２２には、前記取付板２３に連続した外側の立上片２１が嵌るのである。 As shown in FIG. 5, the bracket 9 is provided with a mounting plate 23 perpendicular to the rear portion, and penetrates the engagement pin 14 formed of a flanged pipe in a hole formed in the mounting plate 23 from the inside to the outside. The flange is welded to the inside of the mounting plate 23, and the support rail 15 having a substantially U-shaped cross section that is opened upward over the entire length of the lower edge is bent. The mounting plate 23 is formed with a recess for receiving the thickness of the flange of the engagement pin 14, and the other part is inevitably a projection, but there is also an effect of increasing the strength by the concavo-convex structure. And since the pipe of the engaging pin 14 penetrates the mounting plate 23, the connecting screw 16 can penetrate the center hole 24 thereof. The compatible upper pieces 21 and 21 constituting the support rail 15 are set to a height smaller than the vertical width of the mounting plate 23. The right bracket 9 and the left bracket 9 are mirror images. The outer rising piece 21 continuous with the mounting plate 23 fits into the notch groove 22 formed in the decorative plate 20.

次に、本発明に係る木質系の組立式机の全体を組み立てる工程を図１、図７〜図１０に基づいて説明する。前記連結部材４は、２枚の板材をアングル状に連結した部材であり、両Ｌ脚１，１の脚板７，７の下方後部間に連結部材４をネジ止め固定し、両Ｌ脚１，１を自立状態にする（図７参照）。次に、各Ｌ脚１，１の脚板７，７の内側に前記ブラケット９，９の係合ピン１４，１４を脚板７，７の取付孔１０，１０に嵌挿して保持する（図８参照）。ここで、前記ブラケット９の係合ピン１４，１４が脚板７，７の取付孔１０，１０に嵌挿した状態では、該ブラケット９は簡単に脱落しない程度に保持されている。それから、前記天板２を両脚板７，７間に位置させて両側の支持板１１，１１をそれぞれブラケット９，９の支持レール１５，１５に載支する（図９参照）。この状態では、両脚板７，７間に天板２の係合部１７，１７が嵌り、支持板１１と支持レール１５の嵌合関係によってＬ脚１の外側への変位も規制されるので、天板２は安定に仮支持される。そして、前記天板２の後方へ押して、前記係合部１７，１７の前端部を前記脚板７，７の前端に当接させて、前記螺孔１２，１２と前記取付孔１０，１０の位置を一致させた状態で、側方から係合ピン１４に挿通した連結ネジ１６を支持板１１の螺孔１２に螺合する（図１０参照）。この連結ネジ１６による螺合工程と前後して前記幕板３の両側部を両脚板７，７の後端面に連結ネジ２５でネジ止めする。ここで、断面略コ字形の支持レールに天板の支持板を嵌合状態で載支するので、Ｌ脚が開いて天板が落下する恐れがないので、天板から手を離してそれぞれの側で連結ネジによる固定作業を行うことができる。つまり、一人の作業者でも重い天板を両Ｌ脚の間に簡単に取付けることができる。 Next, the process of assembling the entire wood-based assembly desk according to the present invention will be described with reference to FIGS. 1 and 7 to 10. The connecting member 4 is a member in which two plate members are connected in an angle shape. The connecting member 4 is screwed and fixed between the lower rear portions of the leg plates 7 and 7 of both L legs 1 and 1, and both the L legs 1 and 1 are fixed. 1 is set in a self-supporting state (see FIG. 7). Next, the engaging pins 14 and 14 of the brackets 9 and 9 are inserted into the mounting holes 10 and 10 of the leg plates 7 and 7 and held inside the leg plates 7 and 7 of the L legs 1 and 1 (see FIG. 8). ). Here, in a state where the engaging pins 14 and 14 of the bracket 9 are inserted into the mounting holes 10 and 10 of the leg plates 7 and 7, the bracket 9 is held to such an extent that it does not easily fall off. Then, the top plate 2 is positioned between the leg plates 7 and 7, and the support plates 11 and 11 on both sides are mounted on the support rails 15 and 15 of the brackets 9 and 9, respectively (see FIG. 9). In this state, the engaging portions 17 and 17 of the top plate 2 are fitted between the leg plates 7 and 7, and the outward displacement of the L leg 1 is also regulated by the fitting relationship between the support plate 11 and the support rail 15, The top 2 is temporarily supported stably. Then, the rear end of the top plate 2 is pushed so that the front end portions of the engaging portions 17 and 17 are brought into contact with the front ends of the leg plates 7 and 7, and the positions of the screw holes 12 and 12 and the mounting holes 10 and 10. In the state in which they are matched, the connecting screw 16 inserted through the engagement pin 14 from the side is screwed into the screw hole 12 of the support plate 11 (see FIG. 10). Before and after the screwing step with the connecting screw 16, both sides of the curtain plate 3 are screwed to the rear end surfaces of the leg plates 7 and 7 with the connecting screw 25. Here, since the support plate of the top plate is mounted in a fitted state on the support rail having a substantially U-shaped cross section, there is no fear that the L leg will open and the top plate will fall. Fixing work with connecting screws can be performed on the side. That is, a single operator can easily attach a heavy top plate between both L legs.

ここで、前記幕板３をＬ脚１に連結する構造を図４及び図１０に基づき簡単に説明する。前記幕板３も天板２と同様に取付位置を上下に調節できるようになっている。前記Ｌ脚１の脚板７の後端面の上部位置で、上下部に間隔を置いて連結穴２６，２６を形成するとともに、該連結穴２６の奥部に連通し脚板７の外面に開口したスリット穴２７をそれぞれ形成し、該スリット穴２７に角ナット２８を挿入し、前記連結穴２６に挿入した前記連結ネジ２５を角ナット２８に螺合するようになっている。一方、前記幕板３の両側部には、上下の前記連結穴２６，２６の間隔と同じ間隔で複数対の取付孔２９，２９を設けている。実際には、上下の複数の取付孔２９，…は一定間隔で形成され、そのピッチ間隔に応じて幕板３の高さを調節できるようになっている。ここで、前記幕板３もかなりの重量があり、片手で支えながら前記連結ネジ２５をねじ込む作業は難しい。そこで、前記連結穴２６，２６の近傍にピンを突設し、該ピンを受け入れる穴を前記取付孔２９，…の近傍にそれぞれ設けておき、ピンと穴による係合によって幕板３を所望高さに仮支持し、軽く幕板３を片手で押えながら、前記連結ネジ２５を角ナット２８に螺合して取付けるようにしている。 Here, a structure for connecting the curtain plate 3 to the L leg 1 will be briefly described with reference to FIGS. As with the top plate 2, the curtain plate 3 can be adjusted up and down. At the upper position of the rear end surface of the leg plate 7 of the L leg 1, the connecting holes 26 and 26 are formed at intervals in the upper and lower parts, and the slits are connected to the inner part of the connecting hole 26 and opened to the outer surface of the leg plate 7. Holes 27 are formed, square nuts 28 are inserted into the slit holes 27, and the connecting screws 25 inserted into the connecting holes 26 are screwed into the square nuts 28. On the other hand, on both sides of the curtain plate 3, a plurality of pairs of mounting holes 29, 29 are provided at the same interval as the interval between the upper and lower connecting holes 26, 26. In practice, the upper and lower mounting holes 29 are formed at regular intervals so that the height of the curtain plate 3 can be adjusted according to the pitch interval. Here, the curtain plate 3 also has a considerable weight, and it is difficult to screw the connecting screw 25 while supporting it with one hand. Therefore, a pin is provided in the vicinity of the connecting hole 26, 26, and a hole for receiving the pin is provided in the vicinity of the mounting hole 29,... The connecting screw 25 is screwed onto the square nut 28 while lightly holding the curtain plate 3 with one hand.

尚、前記幕板３は、前記天板２をＬ脚１，１に取付ける前に、該Ｌ脚１，１の後端面に取付けることも可能である。その場合には、前記天板２の後端を幕板３に当接させることにより、前記螺孔１２，１２と前記取付孔１０，１０の位置を一致させるための位置決めに利用することができる。いずれの場合も、クリアランスや公差のため天板２や幕板３の取付位置に誤差が生じるので、先ず天板２と幕板３を取付けるネジを緩く螺合して、全てのネジが所定位置に配置した後にきつく締め付けることが望ましい。 The curtain plate 3 can be attached to the rear end surface of the L legs 1 and 1 before the top plate 2 is attached to the L legs 1 and 1. In that case, by bringing the rear end of the top plate 2 into contact with the curtain plate 3, it can be used for positioning for matching the positions of the screw holes 12, 12 and the mounting holes 10, 10. . In either case, an error occurs in the mounting position of the top plate 2 and the curtain plate 3 due to clearances and tolerances. First, the screws for attaching the top plate 2 and the curtain plate 3 are loosely screwed, and all the screws are in predetermined positions. It is desirable to tighten it tightly after it is placed on.

前記書棚５は、前記両Ｌ脚１，１の間隔の半分の横幅を有し、両側の側板３０，３０の下部間に載置板３１を固定し、中間に仕切板３２を横方向移動可能に設けた構造である。そして、前記書棚５の両側板３０，３０の後端面を幕板３の前面に、幕板３と脚板７の取付手段と同様な取付手段によって取付ける。前記書棚５の取付位置は、変更可能なように幕板３の複数箇所に取付けのための取付孔を形成している。また、前記書棚５は、上下反転させて幕板３に取付けることも可能である。二つの書棚５，５を組み合わせて取付けることにより、多様な使用態様を実現できる。 The bookcase 5 has a width that is half of the distance between the L legs 1 and 1, and a mounting plate 31 is fixed between the lower portions of the side plates 30 and 30 on both sides, and the partition plate 32 can be moved in the horizontal direction. It is the structure provided in. The rear end surfaces of the side plates 30 and 30 of the bookcase 5 are attached to the front surface of the curtain plate 3 by attachment means similar to the attachment means for the curtain plate 3 and the leg plate 7. The mounting position of the book shelf 5 is formed with mounting holes for mounting at a plurality of locations on the curtain plate 3 so as to be changeable. Further, the bookcase 5 can be attached to the curtain plate 3 by turning upside down. Various usage modes can be realized by attaching the two book shelves 5 and 5 in combination.

図１〜図３に示すように、前記天板２の後端両側部に切欠部３３，３３を設けることにより、照明器具３４のアーム３５を、該切欠部３３を用いてクランプ（図示せず）で取付けることができ、また配線コードを該切欠部３３を通して配線することができる。また、前記書棚５の載置板３１の後端両側にも切欠部３６，３６を形成している。前記書棚５の切欠部３６は、該書棚５を幕板３に取付けた後に、仕切板３２を装着するために使用するが、前記天板２の切欠部３３と同様な使い方もできる。 As shown in FIGS. 1 to 3, by providing notches 33, 33 on both sides of the rear end of the top plate 2, the arm 35 of the lighting fixture 34 is clamped using the notches 33 (not shown). ) And the wiring cord can be wired through the notch 33. Further, notches 36 are formed on both sides of the rear end of the placement plate 31 of the book shelf 5. The cutout portion 36 of the bookcase 5 is used to mount the partition plate 32 after the bookcase 5 is attached to the curtain plate 3, but can be used in the same manner as the cutout portion 33 of the top plate 2.

図２に示すように、前記天板２の下方に移動可能なワゴン６を収容し、袖キャビネットとして使用することもできる。図２、図１１及び図１２に示すように、ワゴン６の上面に収納オプション３７を取付けて、上方へ開放した収納ボックスを構成することができる。この収納オプション３７は、平面視コ字形の枠体３８とその開放端間に着脱可能に取付ける保持板３９とからなり、図１１及び図１２に示すように、ワゴン６の上面に取付ける際には平面視四角形の上方開放した収納ボックスとなる。前記天板２の高さが高く、引出し１８の下方の空間が十分余裕があれば、ワゴン６を上面に収納オプション３７を取付けたまま天板２の下方に収容することができる。図１４及び図１５に示したように、天板２の高さが低い場合には、ワゴン６の背面に収納オプション３７を付け替えて、上方へ開放したマガジンラックを構成し、その状態で天板２の下方に収容する。つまり、図１１の想像線で示したように、ワゴン６の背面に枠体３８を付け替えるとともに、前記保持板３９を枠体３８の上下中間部の背面に付け替え、上方へ開放したマガジンラックとするのである。 As shown in FIG. 2, a movable wagon 6 can be accommodated below the top plate 2 and used as a sleeve cabinet. As shown in FIGS. 2, 11, and 12, the storage option 37 can be attached to the upper surface of the wagon 6 to form a storage box opened upward. This storage option 37 comprises a frame 38 having a U-shape in plan view and a holding plate 39 that is detachably attached between its open ends, and as shown in FIGS. 11 and 12, when attached to the upper surface of the wagon 6. The storage box is opened upward in a square in plan view. If the height of the top plate 2 is high and the space below the drawer 18 has a sufficient margin, the wagon 6 can be stored below the top plate 2 with the storage option 37 attached to the upper surface. As shown in FIGS. 14 and 15, when the height of the top plate 2 is low, the storage option 37 is replaced on the back of the wagon 6 to form a magazine rack opened upward, and in this state, the top plate 2 is stored below. That is, as shown by the imaginary line in FIG. 11, the frame body 38 is replaced with the back surface of the wagon 6, and the holding plate 39 is replaced with the back surface of the upper and lower middle portions of the frame body 38 to form a magazine rack opened upward. It is.

前記書棚５は、二つ左右に並べて幕板３に取付けることができ（図１３参照）、また一側に寄せて上下に並べて幕板３に取付けることもできる（図２参照）。更に、図１４に示すように、二つの書棚５，５を一側に寄せて、上部の書棚５を上下反転させて取付けることにより、例えばＡ４ファイルを立てて収容できるボックスを構成できる。また、図１５に示すように、天板２の高さが低い状態では、該天板２の下方と上方にそれぞれ分けて書棚５を幕板３に取付けることができる。尚、図示しないが、前記幕板３をＬ脚１に対してより高く取付けることにより、天板２の上方に二つの書棚５，５を上下に並べて取付けることも、また幕板３の上端部に左右に並べて取付けて上部棚を構成することも可能である。 The bookcases 5 can be attached to the curtain plate 3 side by side (see FIG. 13), or can be attached to the curtain plate 3 side by side up and down (see FIG. 2). Further, as shown in FIG. 14, a box that can accommodate, for example, an A4 file can be configured by bringing the two bookshelves 5 and 5 to one side and attaching the upper bookcase 5 upside down. Further, as shown in FIG. 15, when the height of the top plate 2 is low, the bookcase 5 can be attached to the curtain plate 3 separately below and above the top plate 2. Although not shown, it is possible to mount the bookcases 5 and 5 side by side above the top plate 2 by attaching the curtain plate 3 to the L leg 1 higher. It is also possible to configure the upper shelf by mounting it side by side.

前記Ｌ脚１は、前記連結ネジ１６の頭部が脚板７の側面に突出していても、該前記Ｌ脚１の周囲、特に前縁部を側方へ若干突出した化粧部を形成することにより、左右に同じ机を並べて設置した場合で、Ｌ脚１，１同士を隅間なく接合させることができる。また、左右に机を並べて設置した場合、Ｌ脚１としたことにより、座ったまま隣の机に移動したり、椅子を回転させて隣を向いたりする場合に使用者の足の移動に邪魔にならない。 Even if the head of the connecting screw 16 protrudes from the side surface of the leg plate 7, the L leg 1 forms a decorative portion that slightly protrudes to the side around the L leg 1, particularly the front edge. When the same desk is installed side by side, the L legs 1 and 1 can be joined together without any corners. In addition, when the desks are placed side by side, the L leg 1 makes it difficult to move the user's feet when moving to the next desk while sitting or turning the chair and facing the next. do not become.
