Description

【0001】
【発明の属する技術分野】
本発明は、机上棚における照明装置に係わり、更に詳しくは学習机等の机天板の後部に設けた机上棚に灯具をその位置が可変となるように設けた照明装置に関する。
【0002】
【従来の技術】
従来、机上棚における照明装置は各種提供されており、通常の机上棚を有する学習机においては常備されているものであり、例えば机上棚の棚板下面に沿って前後方向にスライド移動可能に灯具を設けた構造が最も簡単で一般的である。
【0003】
しかし、灯具が前後スライド移動可能なものは、そのスライド案内機構のストロークが棚板の奥行幅によって制限されるので、灯具全体が棚板よりも前方へ突出することはなく、そのため机天板の最も明るい位置が後部寄りであり、通常の筆記作業に使用する机天板の前部における照度が低いといった欠点があった。
【0004】
また、右利きの使用者が筆記作業する場合には、向かって左側から照らすことが望ましく、また左利きでは右側から照らすことが望ましいが、前述の灯具が前後スライド移動する構造のものでは、そのような照明状態は実現できない。そのため、本出願人は先に実公昭61−3060号公報にて開示される如く、灯具が回動可能な照明装置を提供している。
【0005】
前述の公報記載の照明装置は、それぞれの基端部を棚板下面に所定間隔で回動自在に枢着した二本の直杆状回動アームを平面視略X字状交差配置となし、該回動アームの先端部を前記棚板下面前部に配した単一の横長照明灯に回動自在に枢着した構造のものであり、照明灯を左右何方の側からも回動引き出し可能となし、右利き、左利きに対応できるものである。しかし、照明灯の全体を前方へ移動させることは構造的に不可能であり、前記同様に机天板の前部の照度が低いといった欠点を有している。
【0006】
【発明が解決しようとする課題】
そこで、本発明が前述の状況に鑑み、解決しようとするところは、灯具を使用しないときには机上棚の棚板下面下に格納でき、また灯具を使用するときに棚板よりも前方へ引き出して机天板の前部の照度を高める得るとともに、右利き及び左利きにも対応できるように灯具の引き出し角度を自由に無段階に変更することができる机上棚における照明装置を提供する点にある。
【0007】
【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、机天板の後部上位に配設した棚板両側部に一対の伸縮アームの基端を水平回動可能に取付けるとともに、両伸縮アームの先端を横長の灯具の中央寄り位置に間隔を設けて水平回動可能に取付けてなる机上棚における照明装置を構成した。
【0008】
ここで、前記両伸縮アームが最も縮んだ状態で、前記灯具が棚板の下面下に格納されるように、前記両伸縮アームの基端と先端の枢着部位置及び枢着部間の間隔を設定してなること、前記両伸縮アームが最も伸びた状態で、前記灯具が棚板よりも前方へ突出して机天板の略中央部を照らすことが可能なように前記伸縮アームの伸縮長さを設定してなることが好ましい。
【0009】
【発明の実施の形態】
次に添付図面に示した実施形態に基づき更に本発明の詳細を説明する。図1は本発明の照明装置を適用した代表的な実施形態を示し、図2〜図7は照明装置の詳細を示し、図中1は学習机、2は机上棚、3は照明装置、4はワゴンデスクをそれぞれ示している。
【0010】
本実施形態において、学習机1の背面に机上棚2の下部を着脱自在に取付けるとともに、机上棚2に取付けた照明装置3を学習机1の天板5の後部上位に配設している。また、前記学習机1の天板5の下方には移動可能なワゴンデスク4を配置可能としている。
【0011】
前記机上棚2は、学習机1の背面に下部を着脱自在に取付けて天板5の後端から上方へ立ち上がったパネル6と、該パネル6の前面上部に上下に取付位置を変更可能に取付けた棚体7とからなる。そして、前記棚体7は、前記パネル6に取付ける両側の側板8,8の下端間に渡設した棚板9を有し、該棚板9の前縁には仕切板10を嵌着できるようになっている。
【0012】
そして、前記照明装置3は、机天板5の後部上位に配設した棚板9両側部に一対の伸縮アーム11,11の基端を水平回動可能に取付けるとともに、両伸縮アーム11,11の先端を横長の灯具12の中央寄り位置に間隔を設けて水平回動可能に取付けたものである。更に、図5に示すように、前記両伸縮アーム11,11が最も縮んだ状態で、前記灯具12が棚板9の下面下に格納されるように、前記両伸縮アーム11,11の基端と先端の枢着部位置及び枢着部間の間隔を設定し、前記両伸縮アーム11,11が最も伸びた状態で、前記灯具12が棚板9よりも前方へ突出して机天板5の略中央部を照らすことが可能なように前記伸縮アーム11の伸縮長さを設定している。
【0013】
更に詳しくは、前記伸縮アーム11は、中空パイプ状の外筒13に杆体14を単又は複数のスライダー15を介在させて前記外筒13に対して杆体14をスライド可能に内挿した構造のものである。そして、前記外筒13の基端には垂直に軸筒16を固着し、前記棚板9の下面に固定した取付板17に垂設した支軸18に前記軸筒16を回動可能に挿入し且つ該支軸18の先端にストップリング19を嵌着し、伸縮アーム11を棚板9に対して水平回動可能に取付けている。この枢着構造は、前記伸縮アーム11に加わる上下方向の曲げ応力に対して強度が非常に高いので好ましい。また、前記杆体14の先端にはL金具20が固着されており、該L金具20の水平片20Aを前記灯具12のカバー21の後方延長部21Aの下面に水平回動可能に取付けている。ここで、前記杆体14の先端を灯具12に水平回動可能に取付けるには、前記L金具20の水平片20Aの円孔20Bに回動可能にスペーサ22を挿入し、該スペーサ22を貫通させたネジ23をカバー21の後方延長部21Aの下面に固着したナット(図示せず)に螺着している。
【0014】
しかし、本発明において、前記伸縮アーム11の伸縮構造及び棚板9、灯具12への枢着構造は限定されるものではなく、公知の各種の構造を採用できる。例えば、前記伸縮アーム11として、ガスシリンダーやパンタグラフ様の関節を有するものも採用できる。
【0015】
また、前記灯具12は、横長のものであり、前記机上棚2の横幅よりも多少短い寸法に設定され、棚板9の下面下に格納した状態では、その両側端と両側板8,8間に若干の余裕の空間が形成される程度に設定され、前記両伸縮アーム11,11の伸縮による位置変化の自由度を高めている。また、前記灯具12は、カバー21の内部に蛍光灯24が配設され、該カバー21の上部後端には前記後方延長部21Aが設けられている。
【0016】
次に、本発明に係る照明装置3の使用態様を図5〜図7に基づいて説明する。先ず、図5に示すように、前記両伸縮アーム11,11が最も縮んだときには灯具12の略全体が前記棚板9の下面下に格納された状態(実線、点線)となり、両伸縮アーム11,11ともに最も伸びたときには、灯具12の全体が棚板9の前端よりも十分に前方へ突出した状態(二点鎖線)となり、該灯具12が天板5の略中央部に位置し、天板5の前部の照度を高めることができる。
【0017】
また、図6に示すように、一方の伸縮アーム11が最も縮み且つ他方の伸縮アーム11が最も伸びたときであって、伸びた方の伸縮アーム11に沿って灯具12の長手方向を配向すれば、灯具12が棚板9に対して傾斜してその一端部が前方へ大きく突出した状態(実線又は二点鎖線)となり、天板5の前部で筆記作業する場合に、右利き又は左利きの使用者の手影が筆記作業位置に生じないようにすることができる。
【0018】
そして、図7に示すように、一方の伸縮アーム11が最も縮み且つ他方の伸縮アーム11が最も伸びたときであって、灯具12を棚板9と平行に配向すれば、灯具12が棚板9に接近して沿うとともに、天板5の一側に寄った状態(実線又は二点鎖線)となり、学習机1の一側に前記ワゴンデスク4を配置した場合に、該灯具12によってワゴンデスク4の上面をも有効に照らすことができる。
【0019】
更に、図示しないが、前記両伸縮アーム11,11の伸縮度合い及び灯具12の棚板9に対する角度を変えることによって、前記灯具12を無段階で自由に配向させることができる。
【0020】
最後に、前記机上棚2の構造及び机上棚2を学習机1に取付ける構造を簡単に説明する。図2及び図4に示すように、前記机上棚2のパネル6の上部であって、両側端縁に沿って上下に一定間隔で三カ所に係止孔25,…を形成し、前記棚体7を構成する両側板8,8の後端に取付けた取付金具26の上下部に、近接した一対の前記係止孔25,25に嵌合係止するフック27,27を突設し、前記係止孔25,25の対を選択することによって、パネル6に対する棚体7の取付高さを二段階に調節可能としている。
【0021】
また、机上棚2を学習机1に着脱自在に取付ける構造は、図8〜図10に示すように、両脚板28,28の後端間に設けた幕板29の背面であって、上下中間部に所定の間隔を隔てて上向き開放した断面コ字形の支持部材30A,30Bを横設するとともに、前記幕板29の両側縁に後方へ折曲形成した取付縁29Aと脚板28の内面後縁との接合部分であって、上部に所定の間隔を隔てて開口31A,31Bを設け、前記パネル6の下縁に前方へ突設した突縁32を前記支持部材30A又は30Bに落し込み係合するとともに、パネル6の前面側であって下部両側に外向き弾性付勢して設けたラッチ33を前記開口31A又は31Bに係合させて取付けるものである。
【0022】
前記ラッチ33は、パネル6に取付ける本体33Aの内部に圧縮コイルばね33Bを介在させて爪体33Cをスライド可能に挿入するとともに、前記本体33Aの側面を貫通させた把手33Dを前記爪体33Cに固定し、該把手33Dはパネル6を貫通して背面に露出し、爪体33Cを前記開口31から外す場合に前記把手33Dを持って横方向に爪体33Cを移動させて本体33Aに引き込むことができるようになっている。
【0023】
また、図1及び図2において、符号34として示したものは電源プラグを接続できる差込口を設けたコンセントボックスであり、該コンセントボックス34に設けた係合部34Aを利用して、前記パネル6の側縁や天板5の縁部の任意の位置に嵌着できるようになっている。
【0024】
【発明の効果】
以上にしてなる本発明の机上棚における照明装置によれば、灯具を使用しないときには机上棚の棚板下面下に格納でき、また灯具を使用するときに棚板よりも前方へ引き出し、筆記作業位置である机天板の前部の照度を高めることができるとともに、右利き及び左利きにも対応できるように灯具の引き出し角度を自由に無段階に変更することができるのである。更に、灯具を棚板と平行に配向すれば、灯具が棚板に接近して沿い且つ天板の一側に寄った状態となるので、机の一側にワゴンデスクを配置した場合には、該ワゴンデスクの上面を効果的に照らすことができるのである。

BACKGROUND OF THE INVENTION
The present invention relates to an illuminating device on a desk shelf, and more particularly to an illuminating device in which a lamp is provided on a desk shelf provided at the rear of a desk top such as a learning desk so that the position thereof can be changed.
[0002]
[Prior art]
Conventionally, various lighting devices for desktop shelves have been provided, and are usually provided in learning desks having ordinary desk shelves. For example, lamps are slidable in the front-rear direction along the bottom surface of the shelf of the desk shelf. The structure provided with is the simplest and most common.
[0003]
However, when the lamp is slidable back and forth, the stroke of the slide guide mechanism is limited by the depth of the shelf board, so the entire lamp will not protrude forward from the shelf board. The brightest position is near the rear, and there is a drawback that the illuminance at the front of the tabletop used for normal writing work is low.
[0004]
In addition, when a right-handed user performs writing work, it is desirable to illuminate from the left side, and when left-handed, it is desirable to illuminate from the right side. Lighting conditions cannot be realized. For this reason, the present applicant has provided an illuminating device in which a lamp can be rotated as disclosed in Japanese Utility Model Publication No. 61-3060.
[0005]
The illuminating device described in the above-mentioned publication has two straight rod-shaped rotating arms pivotally attached to the bottom surface of the shelf plate at predetermined intervals so that the respective base end portions are pivoted at predetermined intervals. The tip of the pivot arm is pivotally attached to a single horizontally-illuminated lamp arranged at the front of the bottom surface of the shelf. The lamp can be pivoted and pulled out from either the left or right side. It can cope with tonashi, right-handed and left-handed. However, it is structurally impossible to move the entire illumination lamp forward, and there is a drawback that the illuminance at the front of the tabletop is low as described above.
[0006]
[Problems to be solved by the invention]
Therefore, in view of the above-mentioned situation, the present invention intends to solve the problem that the lamp can be stored under the lower surface of the shelf of the desk shelf when it is not used, and the desk can be pulled forward from the shelf when the lamp is used. An object of the present invention is to provide an illuminating device for a desktop shelf that can increase the illuminance of the front part of the top plate and can freely change the pull-out angle of the lamp steplessly so as to be able to cope with right-handedness and left-handedness.
[0007]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention attaches the base ends of a pair of telescopic arms to both sides of the shelf plate arranged at the upper rear part of the tabletop so as to be horizontally rotatable, and extends the front ends of both telescopic arms horizontally. An illuminating device for a desktop shelf, which is mounted so as to be horizontally rotatable with a space near the center of the lamp, is configured.
[0008]
Here, in the state where both the telescopic arms are contracted to the minimum, the position of the pivoting portion at the base end and the distal end of the telescopic arms and the distance between the pivoting portions are stored so that the lamp is stored under the lower surface of the shelf. The telescopic arm has a telescopic length so that the lamp can project forward from the shelf and illuminate a substantially central portion of the tabletop when the telescopic arms are in the most extended state. It is preferable to set the thickness.
