Description

本発明は、昇降天板付きデスク装置に関するものである。   The present invention relates to a desk device with a lifting plate.

従来から、両側に配した脚体を固定脚の内部に可動脚の下部を上下動可能に支持した構造とし、これら固定脚と可動脚との間に駆動機構を設けて該可動脚を昇降可能とし、該可動脚の上端に取付けた天板の高さを調節可能とした昇降天板付きデスク装置は各種提供されている。   Conventionally, the legs arranged on both sides are structured so that the lower part of the movable leg can be moved up and down inside the fixed leg, and the movable leg can be moved up and down by providing a drive mechanism between the fixed leg and the movable leg. Various desk devices with an elevating top plate that can adjust the height of the top plate attached to the upper end of the movable leg are provided.

例えば、特許文献1には、固定脚の内部にガイドローラで支持されて可動脚を上下動可能に設けるとともに、天板の後部を片持ち状に前記可動脚で支持し、該可動脚の側面に設けたラックと固定脚に設けたピニオンとの噛合による駆動機構にて可動脚を昇降させる構造が開示されている。ここで、前記固定脚は、床面に接地する下支持部材の後部に脚板部を立設した側面視L字状の形状となっている。尚、前記可動脚は前記脚板部の内部に上下動可能に設けているので、側面視において脚板部よりも可動脚の横幅は狭くなっており、該可動脚の前後は通常開放されている。   For example, in Patent Document 1, a movable leg is supported in a fixed leg by a guide roller so as to be movable up and down, and a rear part of the top plate is supported by the movable leg in a cantilever manner. The structure which raises / lowers a movable leg with the drive mechanism by meshing | engagement with the rack provided in this and the pinion provided in the fixed leg is disclosed. Here, the fixed leg has an L-shape in a side view in which a leg plate portion is erected on the rear portion of the lower support member that contacts the floor surface. Since the movable leg is provided in the leg plate portion so as to be movable up and down, the lateral width of the movable leg is narrower than the leg plate portion in a side view, and the front and rear of the movable leg are normally open.

また、特許文献2には、机本体の左右袖脚の内部には脚部嵌入孔を上下方向に設け、脚部ユニットは、断面略C字形の支持脚の内部に、同じく断面略C字形の昇降脚を昇降可能に嵌挿するとともに、該支持脚の内部に定位置回動可能に設けたピニオンを昇降脚の内部に設けた上下方向のラック部に噛合したものであり、前記脚部嵌入孔にそれぞれ脚部ユニットの支持脚を上方より嵌入して取付けるとともに、昇降脚の上端に天板の両側部を取付け、更に両側のピニオンをシャフトで連結し、該シャフトに交差させた回転軸をウォームとウォームギヤで連動させ、該回転軸に装着したハンドルで回転させて天板を昇降させる構造が開示されている。   In Patent Document 2, leg insertion holes are provided vertically in the left and right sleeve legs of the desk body, and the leg unit has a substantially C-shaped cross section in the same manner as the support legs having a substantially C-shaped cross section. The lifting leg is inserted so as to be able to move up and down, and a pinion provided inside the supporting leg so as to be pivotable at a fixed position is engaged with a vertical rack provided inside the lifting leg, and the leg is inserted. Fit the legs of the leg unit into the holes from above, and attach both sides of the top plate to the upper end of the lifting legs, connect the pinions on both sides with shafts, and rotate the rotating shaft crossing the shafts. There is disclosed a structure in which a top plate is moved up and down by being interlocked by a worm and a worm gear and rotated by a handle attached to the rotation shaft.

尚、固定脚に対して可動脚を昇降駆動する駆動機構として、特許文献3,4に記載されているように、可動脚の内部に螺軸を定位置回動可能に垂設するとともに、固定脚の内部に設けたナット部材に前記螺軸を螺合し、両側の螺軸を同調回動させることにより、固定脚に対して可動脚を昇降する機構は公知である。しかし、従来の駆動機構は、固定脚と可動脚に機構的にも構造的にも一体的に組み込まれており、サイズや仕様の変更の際には脚体全体の構造を、駆動機構も含めて設計変更しなければならなかった。また、従来は、固定脚がそのまま脚体の外面を構成していたので、外観を重視した形状、構造とし板金加工で作製していたが、可動脚を上下動可能に案内するスライド機構において必然的に導入されるクリアランス及び製造、組立誤差により、ガタつきが大きくなり、天板が安定しないといった問題も有している。   In addition, as described in Patent Documents 3 and 4, as a driving mechanism for moving the movable leg up and down with respect to the fixed leg, a screw shaft is suspended inside the movable leg so as to be rotatable at a fixed position and fixed. A mechanism for raising and lowering the movable leg with respect to the fixed leg by screwing the screw shaft into a nut member provided inside the leg and rotating the screw shafts on both sides synchronously is known. However, the conventional drive mechanism is integrated into the fixed leg and the movable leg, both mechanically and structurally. When changing the size and specifications, the entire structure of the leg, including the drive mechanism, is included. Had to be redesigned. Conventionally, since the fixed leg directly forms the outer surface of the leg body, it has been manufactured by sheet metal processing with a shape and structure that emphasizes the appearance, but in a slide mechanism that guides the movable leg so that it can move up and down. In addition, due to the introduced clearance, manufacturing and assembly errors, there is a problem that the backlash increases and the top plate is not stable.

また通常は、このようなデスクの脚体の外側面と天板の側端面は同一垂直面になるように設定されているため、昇降天板付きデスクを複数台横に並べて設置し、若しくは通常の固定天板を有するデスクの横に昇降天板付きデスクを並べて設置した場合、隣接するデスクの脚体同士を密着させて設置すると、天板の端部が干渉してスムーズに昇降させることができないので、脚体間に隙間を置いて設置する必要がある。しかし、そのような状態に設置していてもデスクが移動して天板同士が接触するようになることもあり、その場合には天板のスムーズな昇降ができない。ここで、前記昇降天板を脚体より内側に位置するように設定することも考慮されるが、外観的には脚体が側方へ突出するのは好ましくない。

Also, since the outside surface of the desk leg and the side edge of the top plate are usually set to be the same vertical surface, multiple desks with elevating top plates are installed side by side. When a desk with a lifting table is placed next to a desk with a fixed top plate, if the legs of adjacent desks are installed in close contact with each other, the edges of the top plate interfere with each other so that they can be raised and lowered smoothly. Since it is not possible, it is necessary to install it with a gap between the legs. However, even if it is installed in such a state, the desk may move and the top plates may come into contact with each other, and in this case, the top plate cannot be raised and lowered smoothly. Here, it is considered to set the elevating table so as to be positioned on the inner side of the leg body, but it is not preferable that the leg body projects laterally in terms of appearance.

Mounting holes 29, 29 corresponding to the pilot holes 26, 26 on both sides of the guide rod 20 are formed at both ends of the member 27, and pilot holes 30 are formed closer to the ends between them. Is formed. The cover member 28 is a plate-like member that is disposed on the upper surface of the connecting member 27 and closes the upper open portion of the leg cover 6. Corresponding through holes 32 and 32 are formed, and an opening 33 having the same shape as the opening 31 is formed. Then, both ends of the connecting member 27 are overlapped on the upper ends of the vertical guide rods 20, 20 arranged in parallel on the front and rear sides, and screws 34 are passed through the mounting holes 29 from above and screwed into the lower holes 26. Link. Then, the cover member 28 is placed on the upper surface of the connecting member 27, and the screw 35 is passed through the through hole 32 from above and screwed into the lower hole 30.

また、前記下連結部材22は、図7及び図8に示すように、前記両縦ガイド杆20,20の下端を連結する板状部材であり、両端部の中央に取付孔36をそれぞれ形成するともに、該取付孔36の両側に前記両側の下穴26,26に対応するように通孔37,37を形成し、更に前側には後述の駆動機構11を取付けるための長孔38を形成している。そして、前記下連結部材22の両端部を両縦ガイド杆20,20の下端面に重ね、下方からネジ34を中央の取付孔36に通して前記中央の下穴26に螺合する。   Further, as shown in FIGS. 7 and 8, the lower connecting member 22 is a plate-like member that connects the lower ends of the vertical guide rods 20 and 20, and has an attachment hole 36 formed at the center of both ends. In both cases, through holes 37 and 37 are formed on both sides of the mounting hole 36 so as to correspond to the pilot holes 26 and 26 on both sides, and a long hole 38 for mounting the drive mechanism 11 described later is further formed on the front side. ing. Then, both end portions of the lower connecting member 22 are overlapped with the lower end surfaces of the vertical guide rods 20, 20, and screws 34 are passed through the central mounting hole 36 from below and screwed into the central lower hole 26.

それから、前記可動脚5の下部を前記ガイドユニット7に対して上下スライド可能に組み付ける際に、合成樹脂製の上スラダー39,39と下スライダー40,40を、前記縦ガイド杆20のレール溝23の内面と前記可動脚5の前後端面との間に介在させて、スムーズに摺動するようにしている。前記上スラダー39は、図9及び図10に示すように、前記縦ガイド杆20のレール溝23内に嵌合するとともに、前記可動脚5の側端面41をその角部も含めて受け入れて摺接する断面略コ字形の摺動部42と、該摺動部42の反対側に突設した固定片43とからなり、該固定片43を前記縦ガイド杆20のレール溝23内の底面部上端に形成した切欠部44に嵌合した状態で、前記連結部材27で押さえ込んで保持する。尚、前記上スラダー39の摺動部42には、前記レール溝23内の突条25,25と嵌合する凹部45,45を形成している。この上スラダー39は、前記ガイドユニット7を組立てる際に両縦ガイド杆20,20に取付ける。   Then, when the lower part of the movable leg 5 is assembled to the guide unit 7 so as to be slidable up and down, the upper ladders 39 and 39 made of synthetic resin and the lower sliders 40 and 40 are connected to the rail groove 23 of the vertical guide rod 20. Between the inner surface of the movable leg 5 and the front and rear end surfaces of the movable leg 5 so as to slide smoothly. As shown in FIGS. 9 and 10, the upper ladder 39 is fitted in the rail groove 23 of the vertical guide rod 20, and receives the side end face 41 of the movable leg 5 including its corners and slides. It comprises a sliding part 42 having a substantially U-shaped cross section in contact with a fixed piece 43 projecting on the opposite side of the sliding part 42, and the fixed piece 43 is connected to the upper end of the bottom surface part in the rail groove 23 of the vertical guide rod 20. In the state of being fitted into the notch 44 formed in the above, the connecting member 27 is pressed and held. The sliding portion 42 of the upper ladder 39 is formed with recesses 45, 45 that fit into the protrusions 25, 25 in the rail groove 23. The upper ladder 39 is attached to the vertical guide rods 20 and 20 when the guide unit 7 is assembled.

また、前記下スライダー40は、図9及び図10に示すように、前記可動脚5の側端面41をその角部も含めて受け入れて外嵌し、前記縦ガイド杆20のレール溝23に対して摺動する摺動部46と、該摺動部46の内側に突設した四角形の突起47とを有し、該突起47を前記可動脚5の側端面41の下端部に形成した四角形の係合穴48に嵌入した状態で、前記摺動部46がレール溝23内に摺動可能に嵌合することによって保持される。   Further, as shown in FIGS. 9 and 10, the lower slider 40 receives the side end face 41 of the movable leg 5 including its corners and externally fits the lower slider 40 to the rail groove 23 of the vertical guide rod 20. And a rectangular protrusion 47 projecting from the inside of the sliding part 46, and the protrusion 47 is formed at the lower end of the side end surface 41 of the movable leg 5. The sliding portion 46 is held by being slidably fitted into the rail groove 23 in a state of being fitted into the engaging hole 48.

ここで、前記ガイドユニット7に対して、前記可動脚5をスライド可能に組付けるには、先ず前記ガイドユニット7の両縦ガイド杆20,20の上端部に前述のように上スライダー39をそれぞれ嵌合した状態で、上連結部材21を構成する連結部材27で両縦ガイド杆20,20の上端を連結する。それから、前記連結部材27の上に前記カバー部材28を載置してネジ止めする。そして、前記下連結部材22は、両縦ガイド杆20,20の下端間に連結しない状態で、前記上連結部材21の開口部33から前記可動脚5の下部を挿入し、両側端面41,41を上スラダー39,39の摺動部42,42間に位置させ、それから前記可動脚5を更に押し込むと、該可動脚5の長さを前記縦ガイド杆20よりも長く設定しているので、下端部がレール溝23より下方へ出現し、前記係合穴48が露出するので、該係合穴48に前記下スライダー40の突起47を前後方向から嵌合してその状態を保持しながら、該可動脚5を上方へ移動させて両下スライダー40,40の摺動部46,46をそれぞれ両縦ガイド杆20,20のレール溝23,23内に収容する。その状態で、前記下連結部材22を両縦ガイド杆20,20の下端間に連結する。   Here, in order to slidably attach the movable leg 5 to the guide unit 7, first, as described above, the upper slider 39 is respectively provided at the upper ends of both the vertical guide rods 20, 20 of the guide unit 7. In the fitted state, the upper ends of the vertical guide rods 20 and 20 are connected by the connecting member 27 constituting the upper connecting member 21. Then, the cover member 28 is placed on the connecting member 27 and screwed. The lower connecting member 22 is inserted between the lower ends of the movable leg 5 through the opening 33 of the upper connecting member 21 in a state where the lower connecting member 22 is not connected between the lower ends of both the vertical guide rods 20, 20. When the movable leg 5 is further pushed in, the length of the movable leg 5 is set to be longer than that of the vertical guide rod 20. Since the lower end portion appears below the rail groove 23 and the engagement hole 48 is exposed, the protrusion 47 of the lower slider 40 is fitted into the engagement hole 48 from the front and rear directions, and the state is maintained. The movable leg 5 is moved upward to accommodate the sliding portions 46, 46 of the lower sliders 40, 40 in the rail grooves 23, 23 of the vertical guide rods 20, 20, respectively. In this state, the lower connecting member 22 is connected between the lower ends of both vertical guide rods 20 and 20.

前記縦ガイド杆20は型材であるので、そのレール溝23の寸法精度は高く、また合成樹脂成形品である上スライダー39と下スライダー40の寸法精度も高く、両縦ガイド杆20,20の上下端を上連結部材21と下連結部材22とで連結したので、両縦ガイド杆20,20の平行度も精度が高いので、前記可動脚5をガイドユニット7に対してガタつきなくスムーズに上下スライド移動させることができるのである。また、前記縦ガイド杆20は型材であるので、所定長さに切断することにより、サイズや仕様の変更も容易にできる。   Since the vertical guide rod 20 is a mold material, the dimensional accuracy of the rail groove 23 is high, and the dimensional accuracy of the upper slider 39 and the lower slider 40 which are synthetic resin molded products is also high. Since the ends are connected by the upper connecting member 21 and the lower connecting member 22, the parallelism of the vertical guide rods 20, 20 is also highly accurate, so that the movable leg 5 can be smoothly moved up and down with respect to the guide unit 7 without rattling. It can be slid. In addition, since the vertical guide rod 20 is a mold material, the size and specifications can be easily changed by cutting to a predetermined length.

尚、この可動脚5とガイドユニット7の組付ける際に、図4に示すように、前記駆動機構11の上下方向に延びた伸縮部11Aを、前記可動脚5の内部に上下に貫通させて配置し、その下端を前記下連結部材22の長孔38を利用して該下連結部材22に回転不能に固定する。ここで、前記駆動機構11の伸縮部11Aは、少なくとも上端部にナット部を備えた軸受筒49と、該軸受筒49に螺合した螺軸50とからなっている。そして、前記上支持部材9の内部に回転可能に前後方向に配した操作軸部11Bの後端部と、前記螺軸50の上端部とを一対の傘歯車、あるいはウォームとウォームギヤからなる方向転換部11Cで連結している。つまり、前記軸受筒49の下端は、前記長孔38を利用して前記下連結部材22に回転不能に固定し、前記螺軸50の上端部は、前記上支持部材9の内部に定位置回転可能に連結し、更に前記方向転換部11Cで操作軸部11Bと連動させている。更に、左右の脚体2,2に組み込んだ前記駆動機構11は、図3及び図4に示すように、それらの方向転換部11C,11Cの間を前記天板1の下面側に横設した連動シャフト11Dで同調回動するように連動させている。尚、本実施形態では、前記駆動機構11は汎用品を用いている。   When the movable leg 5 and the guide unit 7 are assembled, as shown in FIG. 4, a telescopic part 11A extending in the vertical direction of the drive mechanism 11 is vertically penetrated into the movable leg 5. The lower end of the lower connecting member 22 is fixed to the lower connecting member 22 so as not to rotate. Here, the telescopic portion 11A of the drive mechanism 11 includes a bearing cylinder 49 having a nut portion at least at its upper end and a screw shaft 50 screwed into the bearing cylinder 49. Then, the rear end portion of the operation shaft portion 11B rotatably arranged in the front and rear direction inside the upper support member 9 and the upper end portion of the screw shaft 50 are changed in direction by a pair of bevel gears or a worm and a worm gear. It is connected by the part 11C. That is, the lower end of the bearing tube 49 is fixed to the lower connecting member 22 so as not to rotate using the long hole 38, and the upper end portion of the screw shaft 50 is rotated in place inside the upper support member 9. Further, they are connected to each other and further linked to the operation shaft portion 11B by the direction changing portion 11C. Furthermore, the drive mechanism 11 incorporated in the left and right legs 2 and 2 is horizontally provided on the lower surface side of the top plate 1 between the direction changing portions 11C and 11C, as shown in FIGS. The interlocking shaft 11D is interlocked so as to rotate in synchronization. In the present embodiment, the drive mechanism 11 is a general-purpose product.

このように、前記可動脚5とガイドユニット7の組付けた状態で、図4及び図6に示すように、前記脚カバー6の上方開放部から前記ガイドユニット7を落とし込み、前記上連結部材21を構成するカバー部材28を両側面板14,14の上端に載置するとともに、下端の下連結部材22を前記下補強部材17の上面に載置し、該下補強部材17の上面の前後端部にそれぞれ形成した貫通孔51,51に、該下補強部材17の凹溝部に嵌合した前記下支持部材8の後部を下方から貫通した連結ボルト(図示せず)を挿通し、更に該連結ボルトを前記下連結部材22の通孔37,37に挿通して前記縦ガイド杆20の両側の下穴26,26に螺合する。それにより、前記脚カバー6に、前記ガイドユニット7を連結すると同時に、前記下支持部材8を連結することができるのである。   Thus, with the movable leg 5 and the guide unit 7 assembled, the guide unit 7 is dropped from the upper open portion of the leg cover 6 as shown in FIGS. And the lower connecting member 22 at the lower end are placed on the upper surface of the lower reinforcing member 17, and the front and rear end portions of the upper surface of the lower reinforcing member 17 are placed on the upper ends of the side plates 14, 14. A connecting bolt (not shown) that penetrates the rear portion of the lower support member 8 fitted in the recessed groove portion of the lower reinforcing member 17 from below is inserted into the through holes 51 and 51 respectively formed in Is inserted into the through holes 37 of the lower connecting member 22 and screwed into the lower holes 26 of both sides of the vertical guide rod 20. Thereby, the lower support member 8 can be connected to the leg cover 6 at the same time as the guide unit 7 is connected.

また、図1、図2及び図11に示すように、前記脚カバー6の延長カバー部16の前面側には合成樹脂製の化粧カバー52を嵌着している。それには、前記脚カバー6の内部後端に固着した後補強部材53の両側板に形成した角孔54,54に、前記化粧カバー52の嵌合部55の両側面に突設した三角ダボ56,56を抜止め係合させる。図1及び図2に示すように、前記脚カバー6の延長カバー部16は、前記可動脚5の後方の空間を埋めて外観性を高めるとともに、該脚カバー6の後面板15の上部に幕板3を安定良く取付けることができるのである。   As shown in FIGS. 1, 2, and 11, a synthetic resin decorative cover 52 is fitted on the front surface side of the extension cover portion 16 of the leg cover 6. For this purpose, triangular dowels 56 projecting on both side surfaces of the fitting portion 55 of the decorative cover 52 are inserted into square holes 54 and 54 formed on both side plates of the rear reinforcing member 53 fixed to the inner rear end of the leg cover 6. , 56 are engaged with retaining. As shown in FIGS. 1 and 2, the extension cover portion 16 of the leg cover 6 fills the space behind the movable leg 5 to enhance the appearance, and the curtain on the rear plate 15 of the leg cover 6. The plate 3 can be attached stably.

図11及び図12に示すように、前記固定脚4、即ち前記脚カバー6の後面板15の上部には、上下一対となった係止具57,57を左右に2列、合計4個の係止具57,…をネジ58,…で取付けて突設している。この係止具57は後面板15に取付けた状態で上向きフックを構成する。そして、前記幕板3の前面の側端部に形成した合計4個の係止孔59,…を前記脚カバー6の後面板15の係止具57,…に上方から嵌合係止する。尚、図示しない押え部材で前記幕板3の上方移動を規制し、前記係止孔59が係止具57から抜けないようにすることが好ましい。   As shown in FIGS. 11 and 12, on the upper portion of the fixed leg 4, that is, the rear plate 15 of the leg cover 6, a pair of upper and lower locking tools 57, 57 are arranged in two rows on the left and right, for a total of four. The locking tools 57,... Are attached by screws 58,. The locking member 57 constitutes an upward hook when attached to the rear plate 15. Then, a total of four locking holes 59,... Formed in the side edge of the front surface of the curtain plate 3 are fitted and locked to the locking tools 57,. It is preferable to restrict the upward movement of the curtain plate 3 with a pressing member (not shown) so that the locking hole 59 does not come off from the locking tool 57.

ここで、前記幕板3は、通常の固定天板を有するデスクに装着するものを共用しているので、左右の係止具57,57の中心線Pを前記脚カバー6の後面板15の中心線CLと一致させると、前記幕板3の側端面が前記固定脚4、即ち前記脚カバー6の外側の側面板14と同一垂直面になるように設計されている。そこで、本実施形態では、図12に示すように、前記左右の係止具57,57の中心線Pを、前記脚カバー6の後面板15の中心線CLより、距離Dだけ外側になるように設定することにより、前記係止具57,…に前記幕板3の係止孔59,…を係止すると、前記幕板3の側端面が前記固定脚4、即ち前記脚カバー6の外側の側面板14より距離Dだけ側方へ突出することになる。このように設定することにより、図3に示すように、本発明に係る二台の昇降天板付きデスク装置を側方へ密接して設置した場合でも、隣接する両デスクの幕板3,3の側端面同士が接触した状態で、両天板1,1間には2Dの隙間が形成されることになる。因みに、本実施形態では、距離Dは3.5mmである。   Here, since the curtain plate 3 shares what is attached to a desk having a normal fixed top plate, the center line P of the left and right locking tools 57, 57 is connected to the rear plate 15 of the leg cover 6. When matched with the center line CL, the side end surface of the curtain plate 3 is designed to be flush with the fixed leg 4, that is, the side plate 14 on the outer side of the leg cover 6. Therefore, in this embodiment, as shown in FIG. 12, the center line P of the left and right locking members 57, 57 is located outside the center line CL of the rear plate 15 of the leg cover 6 by a distance D. When the locking holes 59,... Of the curtain plate 3 are locked to the locking tools 57,..., The side end surface of the curtain plate 3 is outside the fixed leg 4, that is, the leg cover 6. The side plate 14 protrudes to the side by a distance D. By setting in this way, as shown in FIG. 3, even when the two desk devices with the lifting table according to the present invention are installed close to the side, the curtain plates 3 and 3 of both adjacent desks are installed. With the side end surfaces in contact with each other, a 2D gap is formed between the top plates 1 and 1. Incidentally, the distance D is 3.5 mm in this embodiment.

つまり、両側に最接近させて設置したデスクの天板1,1間に隙間が確保されることから、他の天板で干渉せずに天板1を昇降させてその高さを調節することができる。ここで、本発明に係る昇降天板付きデスク装置を、通常の固定天板を有するデスクと並べて設置する場合でも、隣接する幕板3,3同士が当接した状態でも、両天板間にDの隙間が確保できるので、同様に天板1を固定天板に干渉されずに昇降させることができる。このように、昇降する天板1に隣接する天板との間に隙間が形成されることは、機能上の利点のみならず、不意の指詰の危険性を低減することにもなるので重要であるが、単に天板間の間隔を指の大きさ以上に設定することは、外観性を損なうばかりでなく空間の有効利用が図れない。本実施形態では、前記天板1を昇降するための駆動機構11として、上下方向に延びた伸縮部11Aを軸受筒49に螺合した螺軸50とから構成したネジ軸方式としたので、天板1の昇降速度は遅く、該天板1と隣接する天板との間に指を挟む危険性はないのである。   In other words, since a gap is secured between the top plates 1 and 1 of the desk installed closest to both sides, the height of the top plate 1 can be adjusted by raising and lowering the top plate 1 without interfering with other top plates. Can do. Here, even when the desk device with a lifting table according to the present invention is installed side by side with a desk having a normal fixed top, even when the adjacent curtain plates 3 and 3 are in contact with each other, Since the gap of D can be secured, the top plate 1 can be raised and lowered without interference with the fixed top plate. In this way, the formation of a gap between the top plate adjacent to the top plate 1 that moves up and down is important because it not only provides a functional advantage but also reduces the risk of unintentional finger clogging. However, simply setting the distance between the tops to be larger than the size of the finger not only impairs the appearance but also cannot effectively use the space. In the present embodiment, since the drive mechanism 11 for raising and lowering the top plate 1 is a screw shaft system constituted by a screw shaft 50 in which a telescopic portion 11A extending in the vertical direction is screwed into the bearing cylinder 49, the ceiling The ascending / descending speed of the plate 1 is slow, and there is no danger of pinching a finger between the top plate 1 and the adjacent top plate.

本発明に係る昇降天板付きデスク装置は、図1〜図3に示すように、前記天板1の後縁と幕板3の上端部間に、配線用の上下開放した配線ダクト60が形成され、該配線ダクト60の下方に適宜コード受け61を設けている。前記幕板3の上端の高さは、固定天板を有する通常デスクの天板の高さに略一致させ、複数台の異なるデスクを並べて設置したときに外観性の統一が図れるようにしている。また、通常デスクの天板の高さは70cmに設定されていることが多い。それに対して、パーソナルコンピュータ等のOA機器のキーボード入力作業するデスクでは、天板の高さを65cm程度に設定することが多い。勿論、使用者の体格の相違や高さに対する好みがあり、作業の種類によって天板の高さが画一的に決まるものではない。本発明に係る昇降天板付きデスク装置は、天板1の高さを65cmから80cm程度までは変更できるように十分な調節しろを設定している。前記天板1を最も下げた際にも、前記固定脚4の本体部上端に位置するカバー部材28の上面と、前記上支持部材9の下面との間に25mmの空間が開くように設定し、この間での指詰の可能性を排除している。   As shown in FIGS. 1 to 3, in the desk device with an elevation board according to the present invention, a wiring duct 60 that is opened vertically is formed between the rear edge of the top board 1 and the upper end of the curtain board 3. A cord receiver 61 is appropriately provided below the wiring duct 60. The height of the upper end of the curtain 3 is made to substantially coincide with the height of the top of the normal desk having a fixed top so that the appearance can be unified when a plurality of different desks are installed side by side. . Also, the height of the desk top is usually set to 70 cm. On the other hand, in the desk where keyboard input work of OA equipment such as a personal computer is performed, the height of the top plate is often set to about 65 cm. Of course, there is a user's physique and preference for height, and the height of the top board is not determined uniformly depending on the type of work. In the desk device with an elevation board according to the present invention, a sufficient adjustment margin is set so that the height of the top board 1 can be changed from about 65 cm to about 80 cm. Even when the top plate 1 is lowered to the lowest, a 25 mm space is opened between the upper surface of the cover member 28 located at the upper end of the main body of the fixed leg 4 and the lower surface of the upper support member 9. , Eliminating the possibility of finger jamming during this time.

また、前述のように、前記固定脚4の本体部上端の高さ、つまり前記カバー部材28の高さを低く設定しているにも係わらず、前記可動脚5の後部に沿った位置に前記脚カバー6の後端部に上方へ延長した前記延長カバー部16を設けているので、前記幕板3の上端を通常デスクの天板の高さに略一致させても、従来と同様に前記幕板3の上下部を、前記係止具57,…を用いて取付けることができ、取付強度も十分に確保することができる。更に、前記幕板3の前面と、前記天板1、可動脚5及び上支持部材9の後端との間の空間、即ち前記配線ダクト60の側方空間は、前記延長カバー部16で埋められているので、外観性が向上することは勿論であるが、この部分での指詰も防止することができるのである。   Further, as described above, the height of the upper end of the main body portion of the fixed leg 4, that is, the height of the cover member 28 is set low, but the position of the fixed leg 4 along the rear portion of the movable leg 5 is Since the extension cover portion 16 extending upward is provided at the rear end portion of the leg cover 6, even if the upper end of the curtain plate 3 is substantially coincident with the height of the top plate of the normal desk, The upper and lower portions of the curtain plate 3 can be attached using the locking members 57,..., And sufficient attachment strength can be secured. Further, a space between the front surface of the curtain plate 3 and the rear ends of the top plate 1, the movable leg 5 and the upper support member 9, that is, a lateral space of the wiring duct 60 is filled with the extension cover portion 16. Therefore, it is possible to prevent clogging of the finger at this portion as well as the appearance.
