Description

【0001】
【発明の属する技術分野】
本発明は、テーブルのオプション取付装置に係わり、更に詳しくは例えばテーブルの脚柱にパネルや照明器具等のオプションの支持部材を取付けるためのテーブルのオプション取付装置に関するものである。
【0002】
【従来の技術】
従来、机やテーブル等の天板等の固定部に取付孔を形成し、支柱を該取付孔内に螺合又は嵌挿して立設し、支柱にパネルや照明器具等のオプションを取付けるようになしたものは各種提供されている。
【0003】
また、スチール製パイプの上端に、他の棒状の支持部材を立起状態で取付ける構造として、前記パイプの上端部内に、中央部に支持孔を形成した固定板を溶接し、上端には中央部に挿通孔を形成した合成樹脂製のキャップを取付け、前記支持部材の下端部を前記挿通孔と支持孔とに嵌挿する構造も知られている。
【0004】
しかし、オプションの支持部材を上端キャップに取付けない場合には、前記挿通孔が露出して外観性を損ない、また前記挿通孔を覆うように蓋体を上端キャップの上面に着脱可能に取付けるようになした場合には、オプションの支持部材を上端キャップに取付けるときに、前記蓋体を外さなくてはならず、その際に蓋体が必要になるまで紛失しないように保管しなければならず、その管理に手間がかかるといった不都合がある。それを避けるためには、蓋体付きキャップ又は挿入孔の無いキャップの2種類を使い分けて用いる必要があり、コスト高になる。
【0005】
【発明が解決しようとする課題】
本発明が前述の状況に鑑み、解決しようとするところは、天板を脚柱で支持したテーブルにパネルや照明器具等のオプションを取付けてなるオプション取付装置において、前記脚柱の上端部に取付けた上端キャップの挿通孔を利用してオプションを支持する支持部材を簡単に取付けることができるとともに、オプションの支持部材を取付けない場合には蓋体で挿通孔を覆って外観性を向上させ、オプションの支持部材を取付ける場合には外した蓋体を格納して紛失を防止することが可能なテーブルのオプション取付装置を提供する点にある。
【0006】
【課題を解決するための手段】
本発明は、前述の課題解決のために、天板を脚柱で支持したテーブルにパネル等のオプションを取付けてなるオプション取付装置であって、上端が開放した筒状の前記脚柱の上端部に下方開放した上端キャップを着脱可能に取付け、該上端キャップの中央部に前記オプションの支持部材下端を嵌挿する上下貫通した挿通孔を形成するとともに、内部に上下方向のリブを形成し、該挿通孔を覆う蓋体の閉塞板の下面に複数の嵌合片を突設し、前記上端キャップの上面に前記嵌合片を嵌挿する嵌合部を形成して蓋体を着脱可能となし、上端キャップの上面から外した前記蓋体を閉塞板を前記リブに当接し且つ嵌合片を内壁面に当接して内部に格納してなるテーブルのオプション取付装置を構成した。
【0007】
ここで、前記上端キャップの下端縁には、下方へ開放した切欠部を形成し、該上端キャップの内部に格納した前記蓋体の少なくとも1つの嵌合片を前記切欠部に側方から臨ませてなることが好ましい。
【0008】
更に、前記上端キャップの上面であって前記挿通孔の周囲に段落ちした凹部を形成するとともに、該凹部内に前記嵌合片を嵌挿する嵌合部を形成し、前記凹部内に蓋体の閉塞板を埋設した状態で着脱自在に嵌合してなることが好ましい。
【0009】
また、前記嵌合部が上下に貫通した係合孔であり、前記上端キャップの内部に格納した前記蓋体の閉塞板の少なくとも一部を前記係合孔に上方から臨ませてなることも好ましい。
【0010】
【発明の実施の形態】
次に本発明の実施の形態を添付図面に基づき更に詳細に説明する。図1は本発明を適用するテーブルを示し、図2は本発明によってテーブルの後部に目隠しパネルを立設した状態を示し、図3〜図7は本発明に係るオプション取付装置の要部を示し、図中符号Aはテーブル、Bはオプションの一例としてのパネル、1は天板、2は脚柱、3は固定部材、4は上端キャップ、5は支持部材をそれぞれ示している。
【0011】
本実施形態におけるテーブルAは、異形天板1の四隅部を4本の脚柱2,…で支持し、後部の2本の脚柱2,2は、それぞれ固定部材3,3で天板1に連結した状態で、天板1の一部に形成した湾曲凹部6,6に上端部を露出し、この上端部が露出した脚柱2,2にそれぞれ上端キャップ4を装着し、前記固定部材3と上端キャップ4とで支持部材5を立起状態で保持し、両支持部材5、5を利用してパネルBを取付けたものである。尚、本発明はテーブル以外に同様な構造の机にも適用でき、またオプションとしてはパネル以外に照明器具、電話台、書見台、ペントレー等も採用できるのである。
【0012】
更に詳しくは、前記脚柱2は、上端が開放した筒状であり、本実施形態ではスチール製の丸パイプからなるものを例示した。また、前記固定部材3は、同じくスチール製であり、前記天板1の下面にネジ止め等の適宜な固定手段で取付ける取付体7と、該取付体7に溶接して略水平に延びた支持杆8とからなり、本実施形態では前記支持杆8を角パイプで形成している。そして、前記脚柱2の上端部側面に形成した開口9内に、前記支持杆8を挿入して溶接にて固定するとともに、前記脚柱2内の中央部に位置する当該支持杆8に上下貫通した支持孔10を形成している。
【0013】
また、前記上端キャップ4は、合成樹脂で一体成形したものであり、前記脚柱2の上端に嵌着する本体部11と、該本体部11に下設した一対の脚片12,12とからなる。前記本体部11には、その中央部に上下貫通した挿通孔13を形成している。そして、前記上端キャップ4の本体部11を前記脚柱2の上端縁部14に嵌合するとともに、前記脚柱2内に位置する前記支持杆8の両側部を両脚片12,12で抱え込み且つ該脚片12,12の先端に互いに対向する方向に突設した係合突起15,15で抜け止めしている。
【0014】
そして、図6に示すように、前記オプションの支持部材5の下端を前記上端キャップ4の挿通孔13と前記支持杆8の支持孔10に嵌挿して、立起状態に保持するのである。ここで、前記挿通孔13は、合成樹脂の成形で形成するので寸法精度が高く、前記支持部材5の下端をガタツキ無く嵌挿することが可能である。また、前記支持杆8は、スチール製角パイプで形成しているので、該支持杆8の上面8Aと下面8Bとにそれぞれ支持孔10,10が間隔を隔てた位置に貫通状態で形成されており、この両支持孔10,10に嵌挿した支持部材5の下端は2点で支持されるので、支持部材5の上部に横方向からの力が加わっても強固に支持できるのである。
【0015】
また、前記上端キャップ4の本体部11の上面であって前記挿通孔13の周囲に段落ちした凹部16を形成し、前記凹部16内に蓋体17を着脱自在に嵌合し、前記オプションを取付ける際には、前記蓋体17を取り去って、前記支持部材5を構成する支柱18の下端を前記凹部16に嵌合するとともに、該支柱18の下端に延設した小径の軸部19を前記挿通孔13と支持孔10に嵌挿するようになっている。
【0016】
更に、前記脚片12,12は、本体部11から互いに平行に延びた板状片であり、その先端部の両側縁に沿って前記支持杆8の側面8Cに当接する突縁20,20を形成し、両突縁20,20の先端に三角形状の前記係合突起15,15を突設し、また脚片12,12の基部の外面側には中心線に沿って先端方向になるにつれて低くなる補強リブ21を本体部11内の連結リブ22の延長として設けている。従って、前記脚片12,12は、補強リブ21と突縁20,20が設けられた部分では剛性があるが、中間部は内外への弾力性を備えている。
【0017】
ここで、前記脚片12,12には、アンダーカット部(係合突起15)を有するので、成形金型の一方からの抜きだけでは成形できない。そのため、前記凹部16に、上方から両脚片12,12の各両突縁20,20と係合突起15,15が露出する連通開口23が形成され、該連通開口23の中央部にその間隔よりも直径が大きな円弧を形成して前記挿通孔13となしている。そして、前記連通開口23の両側縁に沿った下方に、その輪郭と同形の中央リブ24,24を形成している。更に、前記各中央リブ24の外側には本体部11の内壁面25から対向する方向に延び且つ間に所定の空間を設けて一対の側方リブ26,26をそれぞれ形成している。
【0018】
ここで、一方の対の側方リブ26,26は、前記本体部11から下方へ延設して挟持片27,27となし、両挟持片27,27の間隔を前記支持杆8の両側面8C,8Cの間隔と一致させ、前記上端キャップ4を脚柱2の上端に嵌着した際に、両挟持片27,27が前記支持杆8の両側面8C,8Cに当接し、上端キャップ4の回転を規制し、前記両脚片12,12の捩れを防止している。つまり、前記挟持片27,27は、上端キャップ4の中心線から偏心した位置に形成されているので、上端キャップ4の回転方向が挟持片27の略幅方向になるから、回転が確実に規制されるのである。
【0019】
前記蓋体17は、図4及び図5に示すように、前記凹部16の平面視形状と同じで、凹部16の深さと厚さが同じ閉塞板28の下面中央部に円筒状の突起29を形成するとともに、その周囲に90°回転対称に4つの板状の嵌合片30,…を突設している。更に、対角位置にある前記二対の嵌合片30,30は互いに平行となっている。
【0020】
一方、前記上端キャップ4の凹部16内には、前記蓋体17の一対の嵌合片30,30を嵌入する係合孔31,31を該凹部16の底面に形成し、前記蓋体17の他の一対の嵌合片30,30は前記連通開口23内に嵌入するような寸法関係に設定している。即ち、本発明における蓋体17の嵌合片30,…を嵌挿する嵌合部は、本実施形態では前記連通開口23と係合孔31,31である。また、上端キャップ4の凹部16内に、蓋体17を嵌着した状態では、前記閉塞板28は該凹部16内に埋設された状態となり、上端キャップ4と蓋体17の上面は略面一になる。
【0021】
また、前記上端キャップ4の本体部11の下部であって、前記挟持片27,27を形成した側の中間部には、本体部11の下端縁に形成した前記脚柱2への嵌合縁32よりも上方へ連続した切欠部33を形成している。この切欠部33は、上端キャップ4を脚柱2に嵌着した状態でも内外に開口しているので、該切欠部33を利用して前記脚柱2の内部に配線したコード(図示せず)を天板1上に引き出すことが可能となっている。
【0022】
そして、前記支持部材5を上端キャップ4の挿通孔13と支持杆8の支持孔10,10とを利用して立設する場合には、前記蓋体17は上端キャップ4から外す必要がある。それには、先ず前記上端キャップ4を脚柱2の上端部から抜き去り、該上端キャップ4の下方から前記蓋体17の突起29等の適所をドライバー等の工具で押して分離する。前記蓋体17を上端キャップ4から外したままでは紛失する恐れがあるので、前記蓋体17の嵌合片30,…を外側に向け、閉塞板28を前記両挟持片27,27の外側面にあてがい、上方へ滑らせながら側方リブ26,26へ至らせると、両側の前記嵌合片30,30の先端が本体部11の内壁面25に当接した状態で、前記蓋体17の全体が本体部11内に格納される。ここで、前記蓋体17は、本体部11内に密嵌しているから、自重で落下することはない。それから、内部に蓋体17を格納したまま、前記上端キャップ4を前述のように脚柱2の上端部に嵌着する。最後に、前記支持部材5の軸部19を上端キャップ4の挿通孔13から支持杆8の支持孔10,10に嵌挿するとともに、支持部材5を構成する支柱18の下端を前記凹部16内に嵌合する。
【0023】
逆に、立起状態の支持部材5を外す場合には、単に該支持部材5を上方へ引き抜いた後、前記上端キャップ4を脚柱2の上端部から抜き去り、図5及び図6に示すように、前記切欠部33内に露出している蓋体17の下方の嵌合片30をドライバー等の工具で引っ掛けて本体部11から引き出し、前記凹部16内に当該蓋体17を嵌着し、上端キャップ4を脚柱2の上端部に嵌着するのである。
【0024】
尚、前記上端キャップ4のをコード挿通孔として利用する場合には、前記蓋体17が配線の妨げになることがある。その場合には、前記蓋体17を、切欠部33とは反対側の他方の側方リブ26,26と内壁面25間に格納することも可能である。しかし、この場合は、前記蓋体17を上端キャップ4の本体部11から引き出すためにドライバー等の工具を引っ掛ける部分が僅かの隙間に有するだけであるので、その作業に手間取ることが予測される。従って、図8に示したように、前記係合孔31の一部の幅を拡大して形成した拡幅部34を通して格納状態の蓋体17の閉塞板28の一部を露出させ、この露出部分をドライバー等の工具で押し出すことができるようにすることも好ましい形態である。
【0025】

BEST MODE FOR CARRYING OUT THE INVENTION
Next, embodiments of the present invention will be described in more detail with reference to the accompanying drawings. 1 shows a table to which the present invention is applied, FIG. 2 shows a state in which a blind panel is erected at the rear of the table according to the present invention, and FIGS. 3 to 7 show main parts of an option mounting device according to the present invention. In the figure, reference numeral A denotes a table, B denotes a panel as an example of an option, 1 denotes a top plate, 2 denotes a pillar, 3 denotes a fixing member, 4 denotes an upper end cap, and 5 denotes a support member.
[0011]
The table A in the present embodiment supports four corners of the odd-shaped top board 1 with four pillars 2, and two rear pillars 2, 2 with fixing members 3, 3 respectively. The upper end is exposed in the curved concave portions 6 and 6 formed in a part of the top plate 1 in the state of being connected to the top plate 1, and the upper end caps 4 are attached to the pillars 2 and 2 where the upper end is exposed, respectively. The support member 5 is held in an upright state by the upper end cap 3 and the upper end cap 4, and the panel B is mounted using the two support members 5, 5. In addition, the present invention can be applied to a desk having a similar structure other than a table, and as an option, a lighting fixture, a telephone stand, a reading stand, a pen tray, and the like can be adopted other than the panel.
[0012]
More specifically, the pillar 2 has a cylindrical shape with an open upper end, and in the present embodiment, a pillar made of a steel round pipe is exemplified. The fixing member 3 is also made of steel, and is attached to the lower surface of the top plate 1 by an appropriate fixing means such as a screw. The supporting member 7 is welded to the attaching member 7 and extends substantially horizontally. In the present embodiment, the support rod 8 is formed of a square pipe. The support rod 8 is inserted into an opening 9 formed on the side surface of the upper end of the pillar 2 and fixed by welding, and the support rod 8 positioned at the center of the pillar 2 is vertically moved. A penetrating support hole 10 is formed.
[0013]
The upper end cap 4 is formed integrally with a synthetic resin, and includes a main body 11 fitted to the upper end of the pillar 2, and a pair of leg pieces 12, 12 provided below the main body 11. Become. The main body 11 has an insertion hole 13 which is vertically penetrated at the center thereof. Then, the main body 11 of the upper end cap 4 is fitted to the upper end edge 14 of the pillar 2, and both sides of the support rod 8 located in the pillar 2 are held by both leg pieces 12, 12. Engagement projections 15, 15 protruding from the tips of the leg pieces 12, 12 in directions facing each other, prevent the leg pieces 12, 12 from coming off.
[0014]
Then, as shown in FIG. 6, the lower end of the optional support member 5 is inserted into the insertion hole 13 of the upper end cap 4 and the support hole 10 of the support rod 8, and is held upright. Here, since the insertion hole 13 is formed by molding a synthetic resin, the dimensional accuracy is high, and the lower end of the support member 5 can be inserted without rattling. Further, since the support rod 8 is formed of a steel square pipe, support holes 10, 10 are formed in the upper surface 8A and the lower surface 8B of the support rod 8, respectively, at penetrating positions at intervals. Since the lower ends of the support members 5 inserted into the support holes 10 are supported at two points, the upper portions of the support members 5 can be firmly supported even when a lateral force is applied.
[0015]
Further, a recess 16 is formed on the upper surface of the main body 11 of the upper end cap 4 around the insertion hole 13, and a lid 17 is removably fitted in the recess 16. At the time of attachment, the lid 17 is removed, the lower end of a column 18 constituting the support member 5 is fitted into the recess 16, and the small-diameter shaft portion 19 extended to the lower end of the column 18 It is designed to fit into the insertion hole 13 and the support hole 10.
[0016]
Further, the leg pieces 12, 12 are plate-like pieces extending in parallel with each other from the main body portion 11, and have protruding edges 20, 20 abutting on the side surface 8C of the support rod 8 along both side edges of the tip portion. The triangular engaging projections 15 are protruded from the tips of the protruding edges 20, 20, and the outer sides of the bases of the leg pieces 12, 12 become closer to the tip along the center line. The lower reinforcing rib 21 is provided as an extension of the connecting rib 22 in the main body 11. Therefore, the leg pieces 12 and 12 have rigidity at the portion where the reinforcing rib 21 and the protruding edges 20 and 20 are provided, but have elasticity inward and outward at the intermediate portion.
[0017]
Here, since the leg pieces 12, 12 have an undercut portion (engaging projection 15), molding cannot be performed only by pulling out from one of the molding dies. Therefore, a communication opening 23 is formed in the recess 16 so that the projections 20, 20 and the engagement protrusions 15, 15 of the leg pieces 12, 12 are exposed from above. Also, the insertion hole 13 is formed by forming an arc having a large diameter. Further, central ribs 24, 24 having the same shape as the contour thereof are formed below the communication opening 23 along both side edges. Further, a pair of side ribs 26 are formed outside the central ribs 24 so as to extend in a direction facing the inner wall surface 25 of the main body 11 and to provide a predetermined space therebetween.
[0018]
Here, one pair of side ribs 26, 26 extends downward from the main body 11 to form holding pieces 27, 27, and the gap between the two holding pieces 27, 27 is set on both sides of the support rod 8. When the upper end cap 4 is fitted to the upper end of the pillar 2, the holding pieces 27, 27 abut against both side surfaces 8 C, 8 C of the support rod 8, and the upper end cap 4 The rotation of the two leg pieces 12, 12 is prevented.

Conversely, when removing the support member 5 in the upright state, simply pull the support member 5 upward and then remove the upper end cap 4 from the upper end of the pillar 2, as shown in FIGS. As described above, the fitting piece 30 below the lid 17 exposed in the notch 33 is hooked with a tool such as a screwdriver and pulled out from the main body 11, and the lid 17 is fitted into the recess 16. The upper end cap 4 is fitted to the upper end of the pillar 2.
[0024]
When the upper end cap 4 is used as a cord insertion hole, the lid 17 may obstruct the wiring. In this case, the lid 17 can be stored between the other side ribs 26, 26 on the opposite side of the notch 33 and the inner wall surface 25. However, in this case, a portion for hooking a tool such as a screwdriver in order to pull out the lid 17 from the main body 11 of the upper end cap 4 has only a small gap, so that it is expected that the work will be troublesome. Therefore, as shown in FIG. 8, a part of the closing plate 28 of the lid 17 in the retracted state is exposed through the widened portion 34 formed by enlarging the width of a part of the engaging hole 31. It is also a preferable embodiment to be able to extrude with a tool such as a screwdriver.
