Description

本発明は、天板を昇降させて高さ位置を変更できる天板付き家具に関する。   The present invention relates to furniture with a top plate that can change the height position by raising and lowering the top plate.

従来のオーバーベッドテーブル(天板付き家具)は、左右一対の支持体(固定脚柱)と、この支持体に沿って上下摺動可能な可動体(可動脚柱)と、により伸縮脚(脚体)を構成し、一方の伸縮脚にガススプリングを設けることで、天板の昇降の補助及び高さ位置の固定を行うようにし、かつ上側滑車(第2滑車部材)と下側滑車(第1滑車部材)とこれら滑車に掛け渡される線条体(同期用線部材)とにより同期手段を構成し、左右の可動体の昇降誤差を生じ難くして、天板の左右両側をバランスよく同期的に昇降させるようにしている(例えば、特許文献1参照)。   A conventional overbed table (furniture with a top plate) is composed of a pair of left and right supports (fixed pedestals) and a movable body (movable pedestals) that can slide up and down along the support. Body), and by providing a gas spring on one of the telescopic legs, the top plate is raised and lowered and the height position is fixed, and the upper pulley (second pulley member) and the lower pulley (first pulley) (1 pulley member) and a linear body (synchronous wire member) spanning these pulleys constitute a synchronizing means, which makes it difficult to raise and lower the left and right movable bodies and synchronizes the left and right sides of the top plate in a balanced manner. (E.g., see Patent Document 1).

特許文献1に記載のオーバーベッドテーブル(天板付き家具)にあっては、可動体(可動脚柱)の上端部(天板支持部)に上側滑車(第2滑車部材)が設けられており、上側滑車の水平回転軸を挿通させる挿通孔が可動体に形成されるようになっている。しかしながら、可動体は天板を支持するため、ある程度の変形や歪み等を考慮して大きめな挿通孔を可動体に形成しなければならず、水平回転軸及び挿通孔の設計誤差を小さくして滑らかに回転する上側滑車を製作することが困難であるという問題がある。   In the overbed table (furniture with a top plate) described in Patent Document 1, an upper pulley (second pulley member) is provided at an upper end portion (top plate support portion) of a movable body (movable pedestal). An insertion hole for inserting the horizontal rotation shaft of the upper pulley is formed in the movable body. However, since the movable body supports the top plate, a large insertion hole must be formed in the movable body in consideration of a certain degree of deformation and distortion, and the design error of the horizontal rotation shaft and the insertion hole is reduced. There is a problem that it is difficult to manufacture an upper pulley that rotates smoothly.

本発明は、このような問題点に着目してなされたもので、天板の左右両側を同期的に昇降させる天板付き家具において、設計誤差を小さくして第2滑車部材を滑らかに回転させることができる天板付き家具を提供することを目的とする。   The present invention has been made paying attention to such problems, and in a furniture with a top plate that moves the left and right sides of the top plate up and down synchronously, the second pulley member is smoothly rotated with a small design error.

The state in which the push rod 17 is pressed and the piston rod 16 can be expanded and contracted is defined as the expanded state, and the state in which the push rod 17 is released and the piston rod 16 is locked is defined as the fixed state.

次に、アーム7の中央収納部72に配置される枢支部材20について、図6を参照して説明する。図6に示すように、枢支部材20は上方が開口しており、テーブル1の内方に配置される側板部76と、テーブル1の外方に配置される側板部77と、が互いに対向して前後方向に延設されている。側板部76と側板部77の下面には底板部78が設けられ、枢支部材20は、断面視で略コ字状をなしている(図10(a)参照)。   Next, the pivot member 20 disposed in the central storage portion 72 of the arm 7 will be described with reference to FIG. As shown in FIG. 6, the pivot member 20 is open at the top, and the side plate portion 76 disposed inside the table 1 and the side plate portion 77 disposed outside the table 1 face each other. And it is extended in the front-back direction. A bottom plate portion 78 is provided on the lower surfaces of the side plate portion 76 and the side plate portion 77, and the pivotal support member 20 is substantially U-shaped in a cross-sectional view (see FIG. 10A).

図6に示すように、側板部76と側板部77の間には、2つの上部滑車部材42が設けられ、これらの上部滑車部材42は、それぞれ水平方向を向く枢軸63を中心に回動し、前方側の上部滑車部材42と後方側の上部滑車部材42は、それぞれ独立して回動されるようになっている。   As shown in FIG. 6, two upper pulley members 42 are provided between the side plate portion 76 and the side plate portion 77, and these upper pulley members 42 rotate around a pivot 63 that faces the horizontal direction. The front upper pulley member 42 and the rear upper pulley member 42 are independently rotated.

また、枢支部材20の前部20aと後部20bには、それぞれアーム7に取り付けるための取付孔79が形成されている。そして、枢支部材20の後部20bの下面は、枢支部材20の前部20aの下面よりも低く形成されており、所定寸法Dの高低差が形成されている(図9参照)。   Further, attachment holes 79 for attachment to the arm 7 are formed in the front portion 20a and the rear portion 20b of the pivot member 20, respectively. The lower surface of the rear portion 20b of the pivot member 20 is formed lower than the lower surface of the front portion 20a of the pivot member 20, and a height difference of a predetermined dimension D is formed (see FIG. 9).

更に、枢支部材20の取付孔79と、アーム7の中央収納部72に設けられたリブ73の取付孔73cと、を合わせて螺着することにより、枢支部材20とアーム7とが連結される(図9参照)。そして、枢支部材20の下面をリブ73の上端に接触させることにより、リブ73の変形や歪み等を防止することができる。   Furthermore, the support member 20 and the arm 7 are connected by screwing together the attachment hole 79 of the pivot member 20 and the attachment hole 73c of the rib 73 provided in the central storage portion 72 of the arm 7. (See FIG. 9). And the deformation | transformation, distortion, etc. of the rib 73 can be prevented by making the lower surface of the pivot member 20 contact the upper end of the rib 73.

図6に示すように、枢支部材20における側板部76には、その上部が切り欠かれた切欠部76aが形成されている。更に、側板部77の中央部は開口されている。尚、前後の上部滑車部材42は、前後に離間して設けられており、前後の上部滑車部材42の間には、本発明における作動部材としての押圧部材19が配置できるようになっている。   As shown in FIG. 6, the side plate portion 76 of the pivotal support member 20 is formed with a notch portion 76 a in which the upper portion is notched. Further, the central portion of the side plate portion 77 is opened. The front and rear upper pulley members 42 are provided to be separated from each other in the front and rear, and the pressing member 19 as an operating member in the present invention can be disposed between the front and rear upper pulley members 42.

このように、上部滑車部材42及び押圧部材19が取り付けられる枢支部材20を設けたことにより、アーム7に細かな設計を施す必要がなくなるので、設計コストを低減できる。また、枢支部材20が補強部材となって、中央収納部72の強度を高めることができる。   As described above, by providing the pivot member 20 to which the upper pulley member 42 and the pressing member 19 are attached, it is not necessary to make a fine design on the arm 7, so that the design cost can be reduced. Further, the pivotal support member 20 becomes a reinforcing member, and the strength of the central storage portion 72 can be increased.

次に、ガススプリング12のプッシュロッド17を押圧するための押圧部材19について図9及び図10を参照して説明する。アーム7の内部には、ガススプリング12のプッシュロッド17を押圧するための押圧部材19が設けられている。この押圧部材19は、側面視で略L字状をなし、押圧部材19の上端部には、操作用ワイヤ部材22が係合されるワイヤ係合部23が形成されており、枢支部材20の側板部76と側板部77との間に配置されている。   Next, the pressing member 19 for pressing the push rod 17 of the gas spring 12 will be described with reference to FIGS. A pressing member 19 for pressing the push rod 17 of the gas spring 12 is provided inside the arm 7. The pressing member 19 is substantially L-shaped in a side view, and a wire engaging portion 23 with which an operation wire member 22 is engaged is formed at the upper end portion of the pressing member 19. The side plate portion 76 and the side plate portion 77 are disposed.

また、押圧部材19の下部で水平方向を向く枢支軸21が設けられ、押圧部材19は、この枢支軸21を軸として揺動されるようになっている。更に、押圧部材19の下端部には、ガススプリング12のプッシュロッド17を押圧する押圧部24が形成されている。   Further, a pivot shaft 21 that faces in the horizontal direction is provided at the lower portion of the pressing member 19, and the pressing member 19 is swung around the pivot shaft 21. Further, a pressing portion 24 that presses the push rod 17 of the gas spring 12 is formed at the lower end portion of the pressing member 19.

尚、押圧部材19の下端部は、側板部77の中央部から外側に延出し、枢支軸21は側板部77の外側で枢支されている。枢支部材20における後部20bが低く形成されているため、枢支軸21を後方側の上部滑車部材42の下方に設けることができるようになっており、押圧部材19の後端部に形成された押圧部24がガススプリング12の上方に位置し、押圧部材19の揺動によってプッシュロッド17を押圧できるようになっている。   The lower end portion of the pressing member 19 extends outward from the central portion of the side plate portion 77, and the pivot shaft 21 is pivotally supported outside the side plate portion 77. Since the rear portion 20 b of the pivot member 20 is formed low, the pivot shaft 21 can be provided below the upper pulley member 42 on the rear side, and is formed at the rear end portion of the pressing member 19. The pressing portion 24 is positioned above the gas spring 12 so that the push rod 17 can be pressed by swinging the pressing member 19.

尚、前述したとおり、ガススプリング12のプッシュロッド17は、アーム7の中央収納部72に形成されたロッド挿通孔73aの下方から挿通され、中央収納部72内に延出されている(図9参照)。そして、枢支軸21の後端側に形成された押圧部24は、プッシュロッド17の上方に位置している。   As described above, the push rod 17 of the gas spring 12 is inserted from below the rod insertion hole 73a formed in the central storage portion 72 of the arm 7 and extends into the central storage portion 72 (FIG. 9). reference). The pressing portion 24 formed on the rear end side of the pivot shaft 21 is located above the push rod 17.

このように、上部滑車部材42は、枢支部材20における側板部76と側板部77の間、即ち枢支部材20における底板部78の上方に設けられるとともに、押圧部材19における押圧部24は、底板部78の下方に配置されている。そのため、上部滑車部材42と押圧部材19における押圧部24とが枢支部材20の底板部78を挟んで離間され、互いに干渉し合わないようになる。   Thus, the upper pulley member 42 is provided between the side plate portion 76 and the side plate portion 77 in the pivot member 20, that is, above the bottom plate portion 78 in the pivot member 20, and the pressing portion 24 in the pressing member 19 is It is disposed below the bottom plate part 78. Therefore, the upper pulley member 42 and the pressing portion 24 of the pressing member 19 are separated from each other with the bottom plate portion 78 of the pivotal support member 20 interposed therebetween, so that they do not interfere with each other.

図10(a)に示すように、操作用ワイヤ部材22は、操作用ワイヤ25と樹脂製のチューブ部材26とを有し、操作用ワイヤ25は、チューブ部材26に挿通され、チューブ部材26内で延設方向に摺動可能になっている。そして、操作用ワイヤ部材22は、チューブ部材26の端部に形成された固定部27によってアーム7に固定されている。尚、押圧部材19は、左右のアーム7内にそれぞれ設けられており、操作用ワイヤ部材22は、各押圧部材19を互いに連結している(図3参照)。   As shown in FIG. 10 (a), the operation wire member 22 includes an operation wire 25 and a resin tube member 26, and the operation wire 25 is inserted into the tube member 26 and is inside the tube member 26. It is possible to slide in the extending direction. The operation wire member 22 is fixed to the arm 7 by a fixing portion 27 formed at the end of the tube member 26. The pressing members 19 are provided in the left and right arms 7, respectively, and the operation wire member 22 connects the pressing members 19 to each other (see FIG. 3).

また、天板2の下面には、左右のアーム7の近傍、かつ前方側の連結杆8が当接する箇所に2つの凹部2aが形成されている(図3参照)。これらの凹部2aによって天板2と連結杆8の間には隙間ができるため、操作部9に向かって延設される操作用ワイヤ部材22が天板2と連結杆8の間の隙間を通れるようになっている。   In addition, two concave portions 2a are formed on the lower surface of the top plate 2 in the vicinity of the left and right arms 7 and at the location where the front connecting rod 8 abuts (see FIG. 3). Since these recesses 2 a create a gap between the top plate 2 and the connecting rod 8, the operation wire member 22 extending toward the operating portion 9 can pass through the gap between the top plate 2 and the connecting rod 8. It is like that.

また、天板2の下面における操作部9の後方側には、操作用ワイヤ部材22が案内される案内部材80が螺着されている。案内部材80には、上方が開口して前後方向に延びる左右2つの案内溝80aが形成されており、右側の案内溝80aには、右側のアーム7から延びる操作用ワイヤ部材22が通されるとともに、左側の案内溝80aには、左側のアーム7から延びる操作用ワイヤ部材22が通されている。   A guide member 80 for guiding the operation wire member 22 is screwed to the rear side of the operation unit 9 on the lower surface of the top plate 2. The guide member 80 is formed with two left and right guide grooves 80a that open upward and extend in the front-rear direction. The operation wire member 22 extending from the right arm 7 is passed through the right guide groove 80a. In addition, an operation wire member 22 extending from the left arm 7 is passed through the left guide groove 80a.

このように、アーム7から延びる操作用ワイヤ部材22は、天板2の下面に形成された凹部2aと、天板2の下面に取り付けられた案内部材80の案内溝80aと、を通されることにより、操作用ワイヤ部材22を天板2の前端部に延伸させ、天板2の中央部から離間した状態で左右方向に通すことができる。そのため、天板2の中央部に配線ダクト70を設けることができるようになっている。   As described above, the operation wire member 22 extending from the arm 7 is passed through the recess 2 a formed on the lower surface of the top plate 2 and the guide groove 80 a of the guide member 80 attached to the lower surface of the top plate 2. Thus, the operation wire member 22 can be extended to the front end portion of the top plate 2 and passed in the left-right direction while being separated from the central portion of the top plate 2. Therefore, the wiring duct 70 can be provided in the central part of the top plate 2.

また、図10(a)に示すように、操作用ワイヤ25は、チューブ部材26の長さよりも長く設けられており、操作用ワイヤ部材22の端部は操作用ワイヤ25が露呈している。操作用ワイヤ25の先端は係合金具28で留められており、この係合金具28が押圧部材19のワイヤ係合部23に係合している。   Further, as shown in FIG. 10A, the operation wire 25 is provided longer than the length of the tube member 26, and the operation wire 25 is exposed at the end of the operation wire member 22. The distal end of the operation wire 25 is fastened with an engagement fitting 28, and the engagement fitting 28 is engaged with the wire engagement portion 23 of the pressing member 19.

そして、図10(b)に示すように、操作用ワイヤ25が内方向に引っ張られると、押圧部材19が揺動して押圧部24が下降する。そして、ガススプリング12のプッシュロッド17が押圧され、ピストンロッド16が伸縮可能な伸縮状態となる。   Then, as shown in FIG. 10B, when the operation wire 25 is pulled inward, the pressing member 19 swings and the pressing portion 24 descends. Then, the push rod 17 of the gas spring 12 is pressed, and the piston rod 16 is expanded and contracted.

枢支部材20の側板部76には、切欠部76aが形成されているため、押圧部材19が揺動した場合にワイヤ係合部23が内方に移動して切欠部76aに入り込み、押圧部材19が枢支部材20とぶつからないようになっている。   Since the notch 76a is formed in the side plate part 76 of the pivotal support member 20, when the pressing member 19 swings, the wire engaging part 23 moves inward and enters the notch 76a. 19 does not collide with the pivot member 20.

尚、ガススプリング12が伸縮状態になると、ガススプリング12内部のガスの付勢力によってピストンロッド16が上昇し、アーム7及び天板2が押し上げられるようになっており、重量のある天板2であっても操作者が天板2を容易に上昇できるようになっている。   When the gas spring 12 is expanded and contracted, the piston rod 16 is raised by the urging force of the gas inside the gas spring 12, and the arm 7 and the top plate 2 are pushed up. Even if it exists, the operator can raise the top plate 2 easily.

操作用ワイヤ25の引っ張り状態が解除されると、押圧部24がプッシュロッド17に押し上げられて押圧部材19が揺動して復帰される。そして、ピストンロッド16がロックされた固定状態となる。このようにして伸縮状態と固定状態を切り替えられるようになっている。尚、押圧部材19が復帰し易いように、枢支部材20の枢支軸21の部位にバネ等の付勢手段を設けてもよい。   When the pulling state of the operation wire 25 is released, the pressing portion 24 is pushed up by the push rod 17 and the pressing member 19 swings and returns. And it will be in the fixed state where the piston rod 16 was locked. In this way, the expansion / contraction state and the fixed state can be switched. In addition, you may provide urging means, such as a spring, in the site | part of the pivot shaft 21 of the pivot member 20 so that the press member 19 may return easily.

次に、天板2の前方側に設けられた操作部9について図11を参照して説明する。図11(a)に示すように、操作部9には、天板2に固定される固定部材29と、水平方向に移動可能な移動部材30と、が設けられている。また、移動部材30の前方側に操作者が移動部材30を移動させるための操作レバー10が設けられている。   Next, the operation part 9 provided in the front side of the top plate 2 is demonstrated with reference to FIG. As shown in FIG. 11A, the operation unit 9 is provided with a fixing member 29 fixed to the top plate 2 and a moving member 30 movable in the horizontal direction. In addition, an operation lever 10 for the operator to move the moving member 30 is provided on the front side of the moving member 30.

固定部材29は平面視で矩形状をなし、その四隅が天板2に螺着されている。固定部材29の後端部には、操作用ワイヤ部材22が保持される保持部31が左右に2つ形成されている。また、固定部材29の上方に組み合わされる移動部材30は、前部(紙面右側)の左右幅が後部(紙面左側)よりも小さく形成されている。   The fixing member 29 has a rectangular shape in plan view, and its four corners are screwed to the top plate 2. At the rear end portion of the fixing member 29, two holding portions 31 for holding the operation wire member 22 are formed on the left and right. Further, the moving member 30 combined above the fixed member 29 is formed such that the left and right widths of the front portion (right side of the drawing) are smaller than the rear portion (left side of the drawing).

更に、移動部材30の前部及び後部には、前後に延びる長孔32が2つずつ形成されている。長孔32の上方から挿通されたボルト33が固定部材29に固定されており、移動部材30が図11(a)に示す通常位置にある場合には、ボルト33は長孔32の前端部に位置している。   Further, two long holes 32 extending in the front-rear direction are formed in the front portion and the rear portion of the moving member 30. When the bolt 33 inserted from above the long hole 32 is fixed to the fixing member 29 and the moving member 30 is in the normal position shown in FIG. 11A, the bolt 33 is at the front end of the long hole 32. positioned.

また、移動部材30の後部には、略半円状をなすプーリ配置部34が形成されている。このプーリ配置部34には、操作用ワイヤ部材22の略中央部が係合するプーリ35が取り付けられている。このプーリ35は、移動部材30に取り付けられたプーリ枢支部材20とプーリ配置部34との間で垂直方向を向く枢軸62を中心に回動可能になっている。   In addition, a pulley arrangement portion 34 having a substantially semicircular shape is formed at the rear portion of the moving member 30. A pulley 35 that engages with a substantially central portion of the operation wire member 22 is attached to the pulley arrangement portion 34. The pulley 35 is rotatable around a pivot shaft 62 that faces the vertical direction between the pulley pivot member 20 attached to the moving member 30 and the pulley arrangement portion 34.

固定部材29の保持部31には、操作用ワイヤ部材22のチューブ部材26の端部に設けられた固定部40が保持されており、固定部40から露呈された操作用ワイヤ25がプーリ35に係合している。プーリ35の前方側の円周面に操作用ワイヤ部材22の略中央部の操作用ワイヤ25が摺動されるようになっている。   The holding portion 31 of the fixing member 29 holds the fixing portion 40 provided at the end of the tube member 26 of the operation wire member 22, and the operation wire 25 exposed from the fixing portion 40 is attached to the pulley 35. Is engaged. The operation wire 25 at the approximate center of the operation wire member 22 is slid on the circumferential surface on the front side of the pulley 35.

また、操作用ワイヤ部材22におけるプーリ35に係合された部位の近傍が、保持部31により保持されることで、操作用ワイヤ25がプーリ35に掛け渡された状態が維持され、操作用ワイヤ25がプーリ35から離脱してしまうことを防止している。   Further, the vicinity of the portion engaged with the pulley 35 in the operation wire member 22 is held by the holding portion 31, so that the state where the operation wire 25 is stretched over the pulley 35 is maintained, and the operation wire 25 is prevented from being detached from the pulley 35.

図11(b)に示すように、操作レバー10が前方向に引かれて移動部材30が前方位置に移動されると、操作用ワイヤ25はチューブ部材26内で摺動されて、プーリ35に係合された操作用ワイヤ25が前方向に牽引されるようになっている。   As shown in FIG. 11B, when the operation lever 10 is pulled in the forward direction and the moving member 30 is moved to the front position, the operation wire 25 is slid in the tube member 26 and is moved to the pulley 35. The engaged operation wire 25 is pulled forward.

また、図3に示すように、左右のアーム7内に設けられた押圧部材19は、操作用ワイヤ部材22によって連結されており、操作者が操作部9における操作レバー10を前方向に引くと、操作用ワイヤ25の左右端部が内方向に移動される。そして、左右の脚体3内部の押圧部材19が同時に動作し、ガススプリング12の伸縮状態と固定状態とが同時に切り換えられるようになっている(図10参照)。   As shown in FIG. 3, the pressing members 19 provided in the left and right arms 7 are connected by an operation wire member 22, and when the operator pulls the operation lever 10 in the operation unit 9 in the forward direction. The left and right ends of the operation wire 25 are moved inward. Then, the pressing members 19 in the left and right legs 3 are simultaneously operated so that the gas spring 12 can be switched between the stretched state and the fixed state simultaneously (see FIG. 10).

次に、左右の脚体3で同期して行われる昇降杆6の昇降動作について、図7から図9及び図12を参照して説明する。図7及び図8に示すように、昇降杆6の内部におけるガススプリング12と連結杆8との間に設けられた滑車部材13は、水平方向を向く枢軸61を中心に回動され、同期用ワイヤ部材14によって上下に移動可能になっている。   Next, the raising / lowering operation | movement of the raising / lowering rod 6 performed in synchronization with the left and right leg 3 is demonstrated with reference to FIGS. 7-9 and FIG. As shown in FIGS. 7 and 8, the pulley member 13 provided between the gas spring 12 and the connecting rod 8 in the lifting rod 6 is rotated around a pivot 61 that faces the horizontal direction, and is used for synchronization. The wire member 14 can move up and down.

アーム7の内部に取り付けられた枢支部材20には、前後に2つの上部滑車部材42が枢支されているとともに、前後の上部滑車部材42,42の間に押圧部材19が配置されており、押圧部材19が揺動されても、押圧部材19が上部滑車部材42にぶつからないようになっている(図9参照)。   Two upper pulley members 42 are pivotally supported on the front and rear of the pivot member 20 attached to the inside of the arm 7, and the pressing member 19 is disposed between the upper and lower upper pulley members 42 and 42. Even if the pressing member 19 is swung, the pressing member 19 does not hit the upper pulley member 42 (see FIG. 9).

図7及び図8に示すように、下部側の下部滑車部材13に架けられた同期用ワイヤ部材14は、アーム7の中央収納部72におけるリブ73に形成されたワイヤ挿通孔73bに挿通されて上部側の上部滑車部材42,42に架け渡され、天板2の下方側を通り、他方の脚体3の下方側にも同様に架け渡されている。   As shown in FIGS. 7 and 8, the synchronization wire member 14 hung on the lower pulley member 13 on the lower side is inserted into a wire insertion hole 73 b formed in a rib 73 in the central storage portion 72 of the arm 7. It is bridged over the upper pulley members 42 on the upper side, passes through the lower side of the top plate 2, and is also bridged over the lower side of the other leg 3 in the same manner.

図9に示すように、同期用ワイヤ部材14における連結部材11の近傍の部位に連結金具45が設けられており、同期用ワイヤ部材14は、この連結金具45を介して連結部材11の上端部に連結されている。   As shown in FIG. 9, a connection fitting 45 is provided at a portion of the synchronization wire member 14 near the connection member 11, and the synchronization wire member 14 is connected to the upper end portion of the connection member 11 via the connection fitting 45. It is connected to.

また、図7に示すように、連結部材11には、略中間部にストッパー46が設けられている。昇降杆6の下面には、ストッパー当接部材47が設けられており、このストッパー当接部材47がストッパー46に当接される位置で、昇降杆6の上昇が停止されるようになっている。   Further, as shown in FIG. 7, the connecting member 11 is provided with a stopper 46 at a substantially intermediate portion. A stopper contact member 47 is provided on the lower surface of the lift rod 6, and the lift of the lift rod 6 is stopped at a position where the stopper contact member 47 is in contact with the stopper 46. .

更に、同期用ワイヤ部材14は、上部前方側の上部滑車部材42から下部側の下部滑車部材13を介して上部後方側の上部滑車部材42に向かってU字状に架け渡されている。右側のアーム7に取り付けられた枢支部材20に枢支された上部前方側の上部滑車部材42から延出する同期用ワイヤ部材14は、枢支部材20の前方側に設けられた離間収納部75に収納された案内滑車部材74に架け渡されている。   Further, the synchronizing wire member 14 is bridged in a U shape from the upper pulley member 42 on the upper front side through the lower pulley member 13 on the lower side toward the upper pulley member 42 on the upper rear side. The synchronizing wire member 14 extending from the upper pulley member 42 on the upper front side that is pivotally supported by the pivoting member 20 attached to the right arm 7 is a separate storage portion provided on the front side of the pivoting member 20. It is bridged over a guide pulley member 74 housed in 75.

そして、同期用ワイヤ部材14は、左側のアーム7に向かって延び、左側のアーム7における前方側の離間収納部75に収納された案内滑車部材74、左側のアーム7に取り付けられた枢支部材20に枢支された上部前方側の上部滑車部材42、の順に架け渡されている。右側のアーム7内の上部後方側の上部滑車部材42から延出する同期用ワイヤ部材14は前後逆の状態で同様に架け渡され、同期用ワイヤ部材14は一体に形成されている。   The synchronization wire member 14 extends toward the left arm 7, and the guide pulley member 74 housed in the front side separation housing portion 75 of the left arm 7, and the pivot member attached to the left arm 7. The upper pulley member 42 on the upper front side that is pivotally supported by 20 is bridged in this order. The synchronizing wire member 14 extending from the upper pulley member 42 on the upper rear side in the right arm 7 is similarly bridged in a reverse state, and the synchronizing wire member 14 is integrally formed.

このように、下部滑車部材13と上部滑車部材42と案内滑車部材74によって、天板2の下面側で2本の同期用ワイヤ部材14が天板2の中央部から前後に離間した状態で左右方向に通されるため、天板2の中央部に配線ダクト70を設けることができるようになっている(図3参照)。   As described above, the lower pulley member 13, the upper pulley member 42, and the guide pulley member 74 cause the two synchronization wire members 14 on the lower surface side of the top plate 2 to be left and right in a state where they are separated from the center portion of the top plate 2. Since it passes through in the direction, the wiring duct 70 can be provided in the center of the top plate 2 (see FIG. 3).

天板2が昇降される際の動きについて、図12の概念図を参照して説明する。前述したように、上部側の上部滑車部材42はアーム7に取り付けられた枢支部材20に枢支されており、下部側の下部滑車部材13は昇降杆6に枢支されており、アーム7と昇降杆6は連結されているため、下部滑車部材13と上部滑車部材42とは、いずれも昇降杆6とともに昇降されるようになっている。   The movement when the top plate 2 is raised and lowered will be described with reference to the conceptual diagram of FIG. As described above, the upper pulley member 42 on the upper side is pivotally supported by the pivot member 20 attached to the arm 7, and the lower pulley member 13 on the lower side is pivotally supported by the lifting / lowering rod 6. Since the elevating rod 6 and the elevating rod 6 are connected, both the lower pulley member 13 and the upper pulley member 42 are moved up and down together with the elevating rod 6.

図12に示すように、上部側の上部滑車部材42のうち、一方の上部滑車部材42に架け渡されている同期用ワイヤ部材14を同期用ワイヤ部材14aとし、他方の上部滑車部材42に架け渡されている同期用ワイヤ部材14を同期用ワイヤ部材14bとして説明する。   As shown in FIG. 12, among the upper pulley members 42 on the upper side, the synchronizing wire member 14 spanned on one upper pulley member 42 is used as a synchronizing wire member 14a, and is spanned on the other upper pulley member 42. The passing synchronization wire member 14 will be described as a synchronization wire member 14b.

例えば、紙面右側の昇降杆6が上昇した場合には、右側の上部滑車部材42が上昇するが、同期用ワイヤ部材14aを連結金具45を介して連結金具11に固定されているため、右側の上部滑車部材42が引き上げられることにより、同期用ワイヤ部材14aによって、左側の下部滑車部材13が連動して右側の上部滑車部材42の移動距離と同じ距離だけ上昇する。   For example, when the lift 6 on the right side of the paper rises, the upper pulley member 42 on the right side rises. However, since the synchronization wire member 14a is fixed to the connection bracket 11 via the connection bracket 45, When the upper pulley member 42 is pulled up, the lower pulley member 13 on the left side is interlocked with the wire member 14a for synchronization and is raised by the same distance as the moving distance of the upper pulley member 42 on the right side.

同様に、紙面左側の昇降杆6が上昇した場合には、左側の上部滑車部材42が上昇するが、同期用ワイヤ部材14bは連結金具45を介して連結金具11に固定されているため、左側の上部滑車部材42が引き上げられることにより、同期用ワイヤ部材14bによって、右側の下部滑車部材13が連動して左側の上部滑車部材42の移動距離と同じ距離だけ上昇する。   Similarly, when the lifting rod 6 on the left side of the paper rises, the upper pulley member 42 on the left side rises, but the synchronization wire member 14b is fixed to the connection fitting 11 via the connection fitting 45, so the left side When the upper pulley member 42 is pulled up, the right lower pulley member 13 is interlocked and raised by the synchronization wire member 14b by the same distance as the moving distance of the left upper pulley member 42.

このように、同期用ワイヤ部材14aによる作用と同期用ワイヤ部材14bによる作用が同時に働いて相互に及ぼしあうため、左右の昇降杆6,6のいずれか一方のみが先行して上昇することがない。即ち、左右の昇降杆6,6が確実に同期して上昇するようになっている。   In this way, the action of the synchronizing wire member 14a and the action of the synchronizing wire member 14b work simultaneously and affect each other, so that only one of the left and right elevating rods 6 and 6 does not advance in advance. . In other words, the right and left elevating rods 6 and 6 are reliably raised in synchronism.

更に、左右の昇降杆6,6が降下する場合においても、左側の昇降杆6と右側の昇降杆6が同時に同じ移動距離だけ連動して降下するように作用する。このようにして、左右の昇降杆6,6の伸縮を同期させるため、左右の昇降杆6,6及び天板2を一体的に昇降させることができる。   Further, even when the left and right elevating rods 6 and 6 are lowered, the left elevating rod 6 and the right elevating rod 6 act so as to be simultaneously lowered by the same movement distance. In this way, the left and right lifting rods 6 and 6 and the top plate 2 can be lifted and lowered integrally in order to synchronize the expansion and contraction of the left and right lifting rods 6 and 6.

即ち、両方の脚体3の伸縮動作が同期されるため、天板2の高さ位置を変更する際に、天板2の左右で高さがずれることなく、天板2の水平状態が維持されて昇降されるようになる。   That is, since the expansion and contraction operations of both legs 3 are synchronized, when the height position of the top plate 2 is changed, the horizontal state of the top plate 2 is maintained without shifting the height between the left and right sides of the top plate 2. Will be moved up and down.

尚、図7及び図8に示すように、昇降杆6の外面には、複数のガイドローラー52が取り付けられており、このガイドローラー52が支持杆5に摺接されている。昇降杆6が上下昇降される際に、これらのガイドローラー52が支持杆5に摺接して回動することで、昇降杆の上下昇降動作がスムーズに行われるようになっている。   As shown in FIGS. 7 and 8, a plurality of guide rollers 52 are attached to the outer surface of the lifting rod 6, and the guide rollers 52 are in sliding contact with the support rod 5. When the elevating rod 6 is moved up and down, these guide rollers 52 are slidably contacted with the supporting rod 5 and rotated, so that the elevating operation of the elevating rod is smoothly performed.

次に、操作者が操作部9を操作して天板2を昇降させる動作全体について説明する。操作者が操作部9の操作レバー10を前方に引いて移動部材30が前方位置に移動されると、プーリ35に係合する操作用ワイヤ25の略中央部が前方に移動され(図11(b)参照)、操作用ワイヤ部材22の両端が均等に移動される。   Next, the whole operation | movement which the operator operates the operation part 9 and raises / lowers the top plate 2 is demonstrated. When the operator pulls the operation lever 10 of the operation unit 9 forward and the moving member 30 is moved to the front position, the substantially central portion of the operation wire 25 engaged with the pulley 35 is moved forward (FIG. 11 ( b)), both ends of the operation wire member 22 are evenly moved.

操作用ワイヤ部材22の端部の操作用ワイヤ25が係合する左右の押圧部材19,19が揺動され、押圧部24が下降してガススプリング12のプッシュロッド17が同時に押圧される(図10(b)参照)。そして、左右のガススプリング12,12が同時に伸縮状態となり、天板2が昇降可能になる。   The left and right pressing members 19, 19 with which the operating wire 25 at the end of the operating wire member 22 engages are swung, the pressing portion 24 is lowered, and the push rod 17 of the gas spring 12 is simultaneously pressed (see FIG. 10 (b)). Then, the left and right gas springs 12 and 12 are simultaneously expanded and contracted, and the top plate 2 can be moved up and down.

このように、左右のガススプリング12,12が同時に伸縮状態に切り換えられるため、いずれか一方のガススプリング12の切り換えが先に生じて、ガススプリング12,12の付勢力の不均衡により天板2が傾いてしまうことを防止できるようになっている。   Thus, since the left and right gas springs 12 and 12 are simultaneously switched to the expanded and contracted state, the switching of one of the gas springs 12 occurs first, and the top plate 2 is caused by imbalance of the urging forces of the gas springs 12 and 12. Can be prevented from tilting.

操作者が天板2を上昇させる際には、ガススプリング12が伸縮状態のまま、即ち操作レバー10を引いたまま、天板2を上方に押し上げることで天板2が上昇される。このとき、ガススプリング12の内部のガスによってピストンロッド16には、上方に向かう力が働くため、重量を有する天板2であっても容易に昇降できる。   When the operator raises the top plate 2, the top plate 2 is raised by pushing the top plate 2 upward while the gas spring 12 is in an expanded / contracted state, that is, with the operation lever 10 being pulled. At this time, since the upward force acts on the piston rod 16 by the gas inside the gas spring 12, even the top plate 2 having a weight can be easily moved up and down.

また、下部滑車部材13と、上部滑車部材42、案内滑車部材74及び同期用ワイヤ部材14によって、天板2の高さ位置が左右でずれないようになっている。更に、操作部9が天板2の略中央部に設けられているため、操作者が天板2に加える力が左右脚体3,3に対して均等に加わるようになっている。   Further, the lower pulley member 13, the upper pulley member 42, the guide pulley member 74, and the synchronizing wire member 14 prevent the height position of the top plate 2 from being shifted from side to side. Furthermore, since the operation part 9 is provided in the substantially center part of the top plate 2, the force which an operator applies to the top plate 2 is applied equally with respect to the left-right leg bodies 3 and 3. FIG.

天板2が任意の位置に移動され、操作者が操作レバー10から手を離して移動部材30が通常位置に戻されると、プーリ35に係合する操作用ワイヤ25の略中央部が後方に移動され、操作用ワイヤ部材22の端部が均等に外方向に移動される。   When the top plate 2 is moved to an arbitrary position and the operator releases the operating lever 10 to return the moving member 30 to the normal position, the substantially central portion of the operation wire 25 that engages with the pulley 35 is moved backward. The end of the operation wire member 22 is evenly moved outward.

更に、操作用ワイヤ部材22の端部の操作用ワイヤ25が係合する左右の押圧部材19,19が揺動し、押圧部24が上昇してガススプリング12のプッシュロッド17の押圧が同時に解除される。そして、左右のガススプリング12,12が同時に固定状態となり、天板2の位置が固定される。   Further, the left and right pressing members 19, 19 with which the operating wire 25 at the end of the operating wire member 22 engages swings, the pressing portion 24 rises, and the pressing of the push rod 17 of the gas spring 12 is simultaneously released. Is done. Then, the left and right gas springs 12, 12 are simultaneously fixed, and the position of the top plate 2 is fixed.

操作者が天板2を降下させる際には、ガススプリング12が伸縮状態のまま、即ち操作レバー10を引いたまま、天板2を下方に押し下げることで天板2が降下される。天板2が任意の位置に移動され、操作者が操作レバー10から手を離して移動部材30が通常位置に戻されると、プーリ35に係合する操作用ワイヤ25が後方に移動され、操作用ワイヤ部材22の端部が同時に外方向に移動される。   When the operator lowers the top plate 2, the top plate 2 is lowered by pushing the top plate 2 downward while the gas spring 12 is in an expanded / contracted state, that is, with the operation lever 10 being pulled. When the top plate 2 is moved to an arbitrary position, the operator releases the operation lever 10 and the moving member 30 is returned to the normal position, the operation wire 25 engaged with the pulley 35 is moved rearward, and the operation is performed. The end portion of the wire member 22 is simultaneously moved outward.

左右の押圧部材19,19が同時に揺動して押圧部24が上昇し、ガススプリング12のプッシュロッド17の押圧が同時に解除される。そして、左右のガススプリング12,12が同時に固定状態となり、天板2の位置が固定される。   The left and right pressing members 19, 19 are simultaneously swung to raise the pressing portion 24, and the pressing of the push rod 17 of the gas spring 12 is simultaneously released. Then, the left and right gas springs 12, 12 are simultaneously fixed, and the position of the top plate 2 is fixed.

次に、アーム7及び枢支部材20の変形例として、図13を参照して説明する。図13は、図9においてC−C断面に対応する縦断正面図である。図13に示すように、アーム7’の中央収納部72における左右の側壁部71には、L字状をなす突起部81,81が形成されている。また、上部滑車部材42が配置される枢支部材20’は、断面視でコ字状をなし、左右の上端は外側に折り返されて溝部82が形成されている。   Next, a modified example of the arm 7 and the pivot member 20 will be described with reference to FIG. FIG. 13 is a longitudinal front view corresponding to the CC cross section in FIG. 9. As shown in FIG. 13, left and right side wall portions 71 of the central storage portion 72 of the arm 7 ′ are formed with L-shaped projections 81, 81. Further, the pivot member 20 ′ on which the upper pulley member 42 is disposed has a U shape in a cross-sectional view, and left and right upper ends are folded outward to form a groove portion 82.

枢支部材20’をアーム7’に取り付ける際には、枢支部材20’の下面がアーム7’の下面に当接して螺着されるとともに、枢支部材20’における左右の溝部82,82とアーム7’の突起部81,81とが係合する。そのため中央収納部72を補強することができ、左右の側壁部71同士が互いに離間される方向、すなわち中央収納部72が左右方向に広がる方向に中央収納部72が変形したり歪んだりすることを防止でき、枢支部材20’が補強部材となってアーム7全体の変形や歪み等を防止できる。   When the pivot member 20 ′ is attached to the arm 7 ′, the lower surface of the pivot member 20 ′ is screwed in contact with the lower surface of the arm 7 ′, and the left and right groove portions 82, 82 of the pivot member 20 ′. And the protrusions 81, 81 of the arm 7 'engage. Therefore, the central storage portion 72 can be reinforced, and the central storage portion 72 is deformed or distorted in a direction in which the left and right side wall portions 71 are separated from each other, that is, in a direction in which the central storage portion 72 extends in the left-right direction. It is possible to prevent the pivoting member 20 ′ from being a reinforcing member and to prevent deformation or distortion of the arm 7 as a whole.

以上、本実施例におけるテーブル1では、天板2の左右側部を支持する左右一対の脚体3は、床面に設置される支持杆5と、この支持杆5に支持されて昇降可能となっている昇降杆6と、により上下方向に伸縮自在に構成され、両脚体3を伸縮させることにより天板2を昇降させて高さ位置を変更でき、かつ可撓性を有する前後一対の同期用ワイヤ部材14の一端が一方の支持杆5に固定されるとともに、同期用ワイヤ部材14の他端が他方の支持杆5に固定されており、同期用ワイヤ部材14が、昇降杆6の下方位置に配置されて水平軸周りに回動する下部滑車部材13と、昇降杆6の上方位置に配置されて水平軸周りに回動する前後一対の上部滑車部材42と、に掛け渡されており、同期用ワイヤ部材14により両脚体3の伸縮動作を同期させるテーブル1において、昇降杆6の上部位置には、前後方向に延びて天板2を支持するアーム7が設けられ、このアーム7には、下部滑車部材13から延びる同期用ワイヤ部材14が挿通されるワイヤ挿通孔73bが開口されるとともに、このワイヤ挿通孔73bに対応した位置に、一対の上部滑車部材42が枢支された枢支部材20が嵌合される中央収納部72が上方に開口されることで、一対の上部滑車部材42が枢支される枢支部材20を、天板2を支持して変形や歪み等が生じる虞があるアーム7とは別部材として製作できるため、枢支部材20の設計誤差をアーム7とは別に設定できるようになり、枢支部材20の設計誤差を小さくして上部滑車部材42を滑らかに回転させることができ、かつ上部滑車部材42を枢支する枢支部材20がアーム20と別部材となっていても、上部滑車部材42と一体的にユニット化された枢支部材20を中央収納部72に嵌合させることで、テーブル1の組立作業を効率よく行うことができる。   As described above, in the table 1 according to this embodiment, the pair of left and right legs 3 that support the left and right side portions of the top plate 2 can be lifted and lowered by being supported by the support rod 5 installed on the floor surface. A pair of front and rear synchronizations that are configured to be vertically extendable by the lifting rod 6 that is configured to be vertically movable, the height position can be changed by moving the legs 3 up and down, and the height position can be changed. One end of the wire member for synchronization 14 is fixed to the one support rod 5, and the other end of the wire member for synchronization 14 is fixed to the other support rod 5. A lower pulley member 13 which is arranged at a position and rotates around a horizontal axis, and a pair of front and rear upper pulley members 42 which are arranged at a position above the elevating rod 6 and rotate around a horizontal axis are stretched over. The expansion / contraction motion of both legs 3 is synchronized by the synchronizing wire member 14. In the table 1 to be moved, an arm 7 that extends in the front-rear direction and supports the top plate 2 is provided at an upper position of the lifting / lowering rod 6, and a synchronization wire member 14 extending from the lower pulley member 13 is inserted into the arm 7. The central housing portion 72 into which the pivot member 20 on which the pair of upper pulley members 42 are pivoted is fitted upward at a position corresponding to the wire insertion hole 73b. By being opened, the pivot member 20 on which the pair of upper pulley members 42 are pivotally supported can be manufactured as a separate member from the arm 7 that supports the top plate 2 and may be deformed or distorted. The design error of the pivot member 20 can be set separately from the arm 7, the design error of the pivot member 20 can be reduced, the upper pulley member 42 can be rotated smoothly, and the upper pulley member 42 can be pivoted. Support Even when the support member 20 is a separate member from the arm 20, it is possible to efficiently assemble the table 1 by fitting the pivot support member 20 unitized with the upper pulley member 42 into the central storage portion 72. Can be done well.

また、中央収納部72は、左右一対の側壁部71を有し、この側壁部71同士を連結するリブ73の上端に枢支部材20が接触されることで、中央収納部72を補強するリブ73の変形や歪み等を枢支部材20により防止することができ、枢支部材20をアーム7の変形や歪み等を防止する補強部材として利用することができる。   The central storage portion 72 has a pair of left and right side wall portions 71, and ribs that reinforce the central storage portion 72 by contacting the pivot member 20 to the upper ends of ribs 73 that connect the side wall portions 71 to each other. 73 can be prevented by the pivotal support member 20, and the pivotal support member 20 can be used as a reinforcing member for preventing the deformation or distortion of the arm 7.

また、枢支部材20は、左右一対の側板部76,77と、この側板部76,77の間の底板部78と、が形成された上方に開口される略コ字形状をなし、上部滑車部材42が一対の側板部76,77の間に配置されることで、上部滑車部材42が側板部76,77と底板部78とにより囲まれて配置されるため、枢支部材20を中央収納部72に取り付ける前において、上部滑車部材42が枢支部材20により保護されるとともに、枢支部材20を中央収納部72に嵌合させた状態において、上部滑車部材42を上方から視認できるため、テーブル1の組立作業やメンテナンス等が行い易くなる。   Further, the pivot member 20 has a substantially U-shape opened upward in which a pair of left and right side plate portions 76 and 77 and a bottom plate portion 78 between the side plate portions 76 and 77 are formed. Since the member 42 is disposed between the pair of side plate portions 76 and 77, the upper pulley member 42 is disposed so as to be surrounded by the side plate portions 76 and 77 and the bottom plate portion 78. Before being attached to the portion 72, the upper pulley member 42 is protected by the pivot member 20, and the upper pulley member 42 can be viewed from above in a state where the pivot member 20 is fitted to the central storage portion 72. The table 1 can be easily assembled and maintained.

また、脚体3は、上下方向に伸縮されることで昇降杆6の昇降の補助及び高さ位置の固定を行うガススプリング12を有し、このガススプリング12のプッシュロッド17を枢支部材20近傍に配置し、プッシュロッド17を作動させる押圧部材19が枢支部材20に枢支されることで、押圧部材19が枢支される枢支部材20を、天板2を支持して変形や歪み等が生じる虞があるアーム7とは別部材として製作できるため、枢支部材20の設計誤差をアーム7とは別に設定できるようになり、枢支部材20の設計誤差を小さくして押圧部材19を滑らかに揺動させることができる。   Further, the leg 3 has a gas spring 12 that assists in raising and lowering the lifting rod 6 and fixing its height position by being expanded and contracted in the vertical direction, and the push rod 17 of the gas spring 12 is connected to the pivot member 20. The pressing member 19 disposed in the vicinity and operating the push rod 17 is pivotally supported by the pivoting member 20, so that the pivoting member 20 to which the pressing member 19 is pivoted is supported by the top plate 2 and is deformed. Since it can be manufactured as a separate member from the arm 7 that may cause distortion or the like, the design error of the pivot member 20 can be set separately from the arm 7, and the pressing member can be reduced by reducing the design error of the pivot member 20 19 can be rocked smoothly.

以上、本発明の実施例を図面により説明してきたが、具体的な構成はこれら実施例に限られるものではなく、本発明の要旨を逸脱しない範囲における変更や追加があっても本発明に含まれる。   Although the embodiments of the present invention have been described with reference to the drawings, the specific configuration is not limited to these embodiments, and modifications and additions within the scope of the present invention are included in the present invention.

例えば、前記実施例では、操作部9をテーブル1の前方側に設けているが、後方側にも同様に設けてもよい。これにより、操作者は、テーブル1の前後どちら側からでも天板2の昇降動作ができるようになる。   For example, in the above embodiment, the operation unit 9 is provided on the front side of the table 1, but may be provided on the rear side in the same manner. As a result, the operator can move the table 2 up and down from either the front or back side of the table 1.
