Description

【０００１】
【発明の属する技術分野】
本発明は、平机と組合せて使用する昇降天板付きワゴンデスクに係わり、更に詳しくは本体部の前部若しくは前部と後部に昇降天板を設けた昇降天板付きワゴンデスクに関する。
【０００２】
【従来の技術】
従来、この種の移動可能なワゴンデスクは、本体部に多段に引出しが設けられ、平机の両脚板間の一方の脚板に接近させて配設して袖付きの机を構成し、又は脚板の外側に設置して脇机として利用できるものである。しかし、ワゴンデスクの天板の高さを平机の両脚板間に収容できるような低い状態に固定したものでは、平机の脚板の外側に配設して脇机として利用する場合には、天板の高さが低過ぎて、通常の用途では使い勝手が悪く、ワゴンデスクの天板は主に書類等の物を載せるためや、机天板よりも多少高さが低い方が使い勝手が良いパーソナルコンピュータ（以下単に「パソコン」と称する）やワードプロセッサ（以下単に「ワープロ」と称する）等のＯＡ機器を載置するための載置台として使用されている。
【０００３】
そのため、ワゴンデスクの天板の高さを、平机の両脚板間に配設できるような低い状態と、平机の脚板の外側に配設して脇机として利用できるように、机天板と同一高さの高い状態との二段階に設定できるように、本体部に昇降天板を昇降機構を介して連結した構造のものが提供されるに至った。
【０００４】
しかし、従来の昇降天板付きワゴンデスクは、本体部の上面の全面に亘って固定天板を設け、その上位に固定天板と略同じ大きさの昇降天板を設けたものであるため、平机からワゴンデスク全体を引き出した状態でしか昇降天板を上昇させて使用することができなかった。また、平机の前部にワゴンデスクを平面視Ｌ字形となるように配置して使用する場合、ワゴンデスクの奥行寸法が大きいと平机から大きく突出して通路スペースを狭くしたり、ワゴンデスクの引出しの引き出し動作に無理が生じる等の問題があるため、この種の昇降天板付きワゴンデスクの奥行幅は小さく設定されていた。つまり、従来の昇降天板付きワゴンデスクは本体部の収容スペースが狭いのが普通であった。
【０００５】
【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、平机の両脚板間に配設して袖付きの机を構成できるとともに、脚板の外側に設置して脇机として利用できる昇降天板を有するワゴンデスクにおいて、奥行寸法を大きくして本体部に広い収納スペースを確保するとともに、平机から全体を引き出さなくても昇降天板を上昇させて使用することができる昇降天板付きワゴンデスクを提供する点にある。
【０００６】
【課題を解決するための手段】
第１発明は、前述の課題解決のために、平机の両脚板間又は脚板の外側に移動させて設置可能で、本体部の上面の前部に前固定天板を設けるとともに、後部に前固定天板より高い位置に後固定天板を設け、前記前固定天板の上位に昇降機構の支持部材にて支持された昇降天板を設け、前記昇降天板を下降させた際に前記後固定天板と面一になるように設定してなる昇降天板付きワゴンデスクを構成した。
【０００７】
ここで、前記前固定天板と昇降天板との間に書類の収納空間を形成し、前記前固定天板と後固定天板との段差部に生じる隙間を幕板部材で閉鎖してなることが好ましい。
【０００８】
また、第２発明は、前述の課題解決のために、平机の両脚板間又は脚板の外側に移動させて設置可能で、本体部の上面の全面に亘って固定天板を設けるとともに、該固定天板の前部と後部との上位にそれぞれ独立した昇降機構の支持部材にて支持された前昇降天板と後昇降天板を設け、更に前記固定天板と前昇降天板との間に書類の収納空間を形成し、前記固定天板の上面で前昇降天板と後昇降天板との境界部に幕板部材を設け、前記両昇降天板を下降させた際に上面が面一になるように設定してなる昇降天板付きワゴンデスクを構成した。
【００１０】
【発明の実施の形態】
次に添付図面に示した実施の形態に基づき更に本発明の詳細を説明する。図１〜図６は第１発明の昇降天板付きワゴンデスクを示し、図中符号Ａはワゴンデスク、Ｂは平机、１は本体部、２は前固定天板、３は後固定天板、４は昇降天板、５は昇降機構をそれぞれ示している。
【００１１】
第１発明のワゴンデスクＡは、本体部１の上面の前部に前固定天板２を設けるとともに、後部に前固定天板２より高い位置に後固定天板３を設け、前記前固定天板２の上位に昇降機構５の支持部材６にて支持された昇降天板４を設け、前記昇降天板４を下降させた際に前記後固定天板３と面一になるように設定してなるものであり、前記本体部１には多段に引出し７，…を設けるとともに、本体部１の下端には複数のキャスター８，…を設けて移動可能となしている。また、前記昇降機構５は、前記昇降天板４を無段階に近い状態で高さ調節できるラチェット式の昇降機構を採用している。
【００１２】
具体的には、前記ワゴンデスクＡは、本体部１の両側板９，９の後部（全奥行幅の略１／３部分）に上方へ延設した保高部１０，１０を形成し、両側板９，９の前部（全奥行幅の略２／３部分）の上端に前記前固定天板２を取付けるとともに、前記保高部１０，１０の上端に前記後固定天板３を取付け、前記前固定天板２と前記後固定天板３とで形成される段差部を埋めるように前記昇降天板４を配している。ここで、前記昇降機構５の機構本体１１は、図２に示すように各側板９の内部に組み込まれている。また、前記昇降機構５を構成する前記支持部材６は側板９の上端から上方に延び、両支持部材６，６の上端には奥行方向に配向した取付杆１２，１２を固定し、該の上面に前記昇降天板４を固定している。そして、前記両取付杆１２，１２の前後下面にはゴム製等の緩衝具１３，１３を取付け、前記昇降天板４を最下降させた際に前記前固定天板２の上面に当接するようにし、この状態で前記昇降天板４と後固定天板３の上面は面一になるように設定されている。
【００１３】
図２及び図３に示すように、前記昇降天板４を最下降させた際にも、前記前固定天板２と昇降天板４との間及び両取付杆１２，１２の間に書類の収納空間１４を形成するとともに、該収納空間１４に置いた書類が後方へ移動し、前記前固定天板２と後固定天板３との段差部に生じる隙間から侵入しないように、該隙間を幕板部材１５で閉鎖している。
【００１４】
次に、前記ワゴンデスクＡの昇降機構５を図２に基づいて簡単に説明する。前記昇降機構５は、前記側板９の前後中央部位置に設けた図示しない縦溝内に、前記支持部材６を上下動可能に配設するとともに、支持部材６の基部の後縁に沿って形成したラック１６を、前記縦溝内に水平な軸芯回りに回転可能に配設した歯車部材１７のピニオン１８に噛合させ、支持部材６の上下動（昇降）に伴って歯車部材１７が回転するのである。ここで、左右の各歯車部材１７，１７は、本体部１の収納空間に横設したシャフト（図示せず）の両端に軸芯が固定されており、一体となって回転し、もって左右の支持部材６，６は同調して上下動するのである。また、前記昇降機構５を構成するストッパー構造は、前記歯車部材１７の回転を規制することによって、間接的に支持部材６の下降を規制するが、支持部材６の上昇は規制しない構造を例示している。前記歯車部材１７には、ピニオン１８と並設してラチェット１９を一体形成し、あるいは分離形成して回転に対して一体化し、該ラチェット１９に本体部１に対して固定的な支軸にて回動可能に設けた駒片２０の爪を噛合し、前記支持部材６が下降する方向に対する歯車部材１７の一方向回転のみ規制している。また、前記駒片２０は、図示しないが支軸を中心に前記爪がラチェット１９に噛合する方向に板ばね等で弾性付勢している。また、前記支持部材６を下動、即ち昇降天板４を下降させるために、弾性付勢力に抗して前記駒片２０を回動させて爪をラチェット１９から引き離し、歯車部材１７が自由回転できる状態にすべく、前記支持部材６に沿って操作杆２１を配し、前記昇降天板４の両側にそれぞれ設けた操作レバー２２の操作に伴って前記操作杆２１が変移して前記駒片２０を傾動させるようにしている。
【００１５】
次に、前記ワゴンデスクＡと平机Ｂとを組合わせて使用する使用形態を図４〜図６に基づいて説明する。前記平机Ｂは、机天板２３の両側に脚板２４，２４を有し、両脚板２４，２４間の上部であって、机天板２３の下面側に沿った左右に上段引出し２５，２５を設け、両脚板２４，２４間の奥部に後幕板２６を設けた通常構造のものである。
【００１６】
本発明のワゴンデスクＡは、平机Ｂの両脚板２４，２４間又は脚板２４の外側に移動させて設置可能で、また本体部１の後部を平机Ｂの天板２３下に位置させたまま使用することができるようになっている。図４は、前記ワゴンデスクＡの後部、即ち前記後固定天板３に対応する部分を平机Ｂの天板２３下に収容した状態で、前記昇降天板４を上昇させて前記天板２３と面一に設定し且つ昇降天板４の後縁を天板２３の前縁に接合した使用形態を示している。この場合、ワゴンデスクＡの本体部１の奥行幅が大きく、内部の収納スペースを広くしても、該ワゴンデスクＡの平机Ｂから突出量を抑制することができるから、前方の通路を狭くすることがなく、また本体部１の前方の作業空間を確保でき、前記引出し７，７の引き出し動作も容易である。この図４に示した使用形態が本発明の特徴を最も良く表したものである。
【００１７】
また、図５に示すように、前記昇降天板４を下降させて後固定天板３と面一にした状態で使用することも可能である。この状態のまま、ワゴンデスクＡを平机Ｂの側部に配して脇机として使用することもでき、脇机の使用形態で昇降天板４を上昇させて机天板２３と面一にすれば、天板上面の有効面積が広くなる。そして、図５に示した状態で、ワゴンデスクＡを平机Ｂの天板２３下に完全に押し込んで、当該ワゴンデスクＡを袖キャビネットとして使用することも勿論可能である（図６参照）。
【００１８】
次に、図７に基づいて第２発明のワゴンデスクＡを説明する。本発明のワゴンデスクＡは、本体部１の上面の全面に亘って固定天板２７を設けるとともに、該固定天板２７の前部（全奥行幅の略２／３部分）と後部（全奥行幅の略１／３部分）との上位にそれぞれ独立した昇降機構５，５の支持部材６，６にて支持された前昇降天板２８と後昇降天板２９を設け、前記両昇降天板２８，２９を下降させた際に上面が面一になるように設定したものである。
【００１９】
また、前記固定天板２７と前昇降天板２８との間には、前記同様に書類の収納空間１４を形成し、前記固定天板２７の上面で前昇降天板２８と後昇降天板２９との境界部に幕板部材３０を設け、前記収納空間１４に置いた書類が後昇降天板２９下へ侵入しないようにしている。その他の構成は、前記同様であるので、同一構成には同一符号を付してその説明は省略する。
【００２０】
この第２発明のワゴンデスクＡは、前記後昇降天板２９を最下降させた場合には、第１発明と同様な使用形態を実現でき、それに加えて前昇降天板２８と後昇降天板２９とを独立して高さを調節可能であるので、所定の高さ関係に設定することができ、例えば前昇降天板２８より後昇降天板２９を高く設定し、該後昇降天板２９にパソコンやワープロのモニターを載置し、前記前昇降天板２８にキーボードやマウスを載置して使用することができる。
【００２１】
