【発明の属する技術分野】
本発明は、キャビネットの多連扉装置に係わり、更に詳しくはキャビネット本体の開口部に引違い可能に設けた複数の扉体を、一側端の扉体における施錠操作によって全ての扉体を閉扉状態に維持することが可能なキャビネットの多連扉装置に関する。
【０００２】
【従来の技術】
従来、キャビネット本体の開口部に、少なくとも２枚以上の扉体を該開口部上下に配したレールに沿って引違い可能となして奥行方向前後に配設するとともに、後側に位置する扉体はその一側端部が前側に位置する扉体の横幅内でのみ相対的に移動可能となした多連扉装置は、既に提供されている。
【０００３】
この種の多連扉装置は、左右何れかの端部に位置する扉体を開閉操作することによって、他の扉体が連動して開閉動作する構造のものであり、左右何れの側からも開閉することができる性質上、全ての扉体を閉扉状態に維持するために、左右両側端に位置する各扉体に、閉扉時に本体の框部に係脱する施錠具をそれぞれ独立的に設けていた。
【０００４】
しかし、扉体を開閉する場合、必ずしも左右一側のみの扉体を開閉するとは限らい。例えば、キャビネットに収容した場所が不明な物品を探す場合、右側端の扉体の施錠具を解錠し、該扉体を左方向へ開扉して目的物品が無かった場合には、左側端の扉体の施錠具を解錠し、該扉体を右方向へ開扉して目的物品を探す必要がある。そして、目的の物品が見つかれば、左右両側端の扉体をそれぞれ閉扉した後に、それぞれの施錠具を施錠操作しなければないない。このように、両側端の扉体に独立して施錠具を設けた場合には、開扉、閉扉時に、左右両側の施錠具をそれぞれ操作しなければならず、非常に手間がかかるものであった。
【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、左右何れかの端部に位置する扉体を開閉操作することによって、他の扉体が連動して開閉動作する構造の多連扉装置であって、閉扉状態において左右一側端に位置する扉体に設けた施錠具を施錠操作することによって、左右他側端の扉体の開扉動作を不能としてなるキャビネットの多連扉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、キャビネット本体の開口部に、キャビネット本体の開口部に、少なくとも２枚以上の扉体を該開口部上下に配したレールに沿って引違い可能となして奥行方向前後に配設するとともに、後側に位置する扉体はその一側端部が前側に位置する扉体の横幅内でのみ相対的に移動可能となし、開口部の左右一側端に位置する第１扉体には閉扉時に本体の框部に係脱する施錠具と該施錠具を操作することによって駆動する連動手段を設け、左右他側端に位置する第２扉体には係合部を設け、前記開口部の上側又は下側に沿って規制手段を設け、全ての扉体が閉扉状態において前記施錠具の施錠操作による連動手段の駆動に伴って前記規制手段が連動して前記係合部に係合し、第２扉体の開扉動作を不能としてなるキャビネットの多連扉装置において、前記連動手段が第１扉体の裏面側に上下動可能に設けた連動杆であって施錠具の施錠操作に伴って上動するものであり、前記規制手段が中央部を上レールの近傍に奥行方向の支軸にて傾動可能に支持した規制杆であって一端部が前記連動杆の上端で押し上げられることにより他端部が押し下げられて第２扉体の裏面側に突設した係合部を当止するものであるキャビネットの多連扉装置を構成した。
【０００７】
ここで、後側に位置する扉体をその一側端部が前側に位置する扉体の横幅内でのみ相対的に移動可能となすために、前側に位置する各扉体の裏面両側部に沿って縦補強部材を突設するとともに、後側に位置する各扉体の左右一端部の前面側にストッパー部材を突設し、該ストッパー部材を前側に位置する扉体の両縦補強部材間に位置させるべく、前記扉体の表面板の一側部には、ストッパー部材の一部を受け入れる開口を形成するとともに、その下方に横長の係合孔を形成し、前記ストッパー部材は、硬質合成樹脂製のストッパー本体と、軟質合成樹脂製又は合成ゴム製の緩衝部材とから構成され、該ストッパー本体の取付部を、前記開口内に挿入して表面板と前記縦補強部材で形成される空間内に位置させるとともに、該取付部から下方に延設した脚片の下端爪部を前記係合孔に裏面側から無理嵌めし、前記開口から前方へ突出した該ストッパー本体の当止部に前記緩衝部材を外嵌して取付けてなることが好ましい。
【０００８】
【発明の実施の形態】
次に本発明の実施形態を添付図面に基づき更に詳細に説明する。図１は各扉体を閉扉した状態を示し、図２は左側又は右側を開扉した状態を示し、図３は本発明の要部を示し、図４〜図１１は各部の詳細を示している。図中、１はキャビネット本体、２は開口部、３は扉体、４はレールをそれぞれ示している。
【０００９】
本発明に係るキャビネットは、本体１の開口部２に、少なくとも２枚以上の扉体３，…を該開口部２上下に配したレール４に沿って引違い可能となして奥行方向前後に配設するとともに、後側に位置する扉体３はその一側端部が前側に位置する扉体３の横幅内でのみ相対的に移動可能となし、左右何れかの端部に位置する扉体３を開閉操作することによって、他の扉体３が連動して開閉動作する構造のものである。本実施形態では、３枚の扉体３，…を設けた例を示し、開口部２の右側端に位置する扉体３を第１扉体３Ａ、左側端に位置する扉体３を第２扉体３Ｂ、中間に位置する扉体３を中間扉体３Ｃとし、奥行方向前側から順に第１扉体３Ａ、中間扉体３Ｃ、第２扉体３Ｂを引違い可能に配設している。尚、本発明においては、前記中間扉体３Ｃがなくても、また中間扉体３Ｃが複数あっても何ら差し支えない。
【００１０】
前記開口部２の上下に配設した上レール４Ａと下レール４Ｂには、各扉体３，…をそれぞれ移動可能に案内する突条５，…が３本並設されている。そして、後側に位置する扉体３をその一側端部が前側に位置する扉体３の横幅内でのみ相対的に移動可能となすために、各扉体３の裏面両側部に沿って縦補強部材６，６を突設するとともに、中間扉体３Ｃの右端部の前面側にストッパー部材７を突設し、該ストッパー部材７を前側に位置する第１扉体３Ａの両縦補強部材６，６間に位置させ、同様に第２扉体３Ｂの右端部の前面側にストッパー部材７を突設し、該ストッパー部材７を前側に位置する中間扉体３Ｃの両縦補強部材６，６間に位置させ、各ストッパー部材７が前側の扉体３の両縦補強部材６，６間でのみ移動可能となしている。
【００１１】
従って、先ず図１に示した閉扉状態から図２(a) に示すように、左側端の第２扉体３Ｂを右方向に開扉すると、該第２扉体３Ｂのストッパー部材７は前側の中間扉体３Ｃの両縦補強部材６，６間を自由に移動し、第２扉体３Ｂの該ストッパー部材７が中間扉体３Ｃの右側の縦補強部材６に当接すると、中間扉体３Ｃは第２扉体３Ｂに連れられて右方向に開扉動作し、該中間扉体３Ｃのストッパー部材７は前側の第１扉体３Ａの両縦補強部材６間を自由に移動し、中間扉体３Ｃの該ストッパー部材７が第１扉体３Ａの右側の縦補強部材６に当接するまで移動し、全開扉状態となる。また、図１に示した閉扉状態から図２(b) に示すように、右側端の第１扉体３Ａを左方向に開扉すると、該第１扉体３Ａの右側の縦補強部材６が後側の中間扉体３Ｃのストッパー部材７に当接するまで自由に移動し、当接すると中間扉体３Ｃは第１扉体３Ａに連れられて左方向に開扉動作し、該中間扉体３Ｃの右側の縦補強部材６が後側の第２扉体３Ｂのストッパー部材７に当接するまで自由に移動し、全開扉状態となる。
【００１２】
そして、図３〜図９に示すように、本発明は、開口部２の左右一側端に位置する第１扉体３Ａには閉扉時に本体１の框部８に係脱する施錠具９と該施錠具９を操作することによって駆動する連動手段１０を設け、左右他側端に位置する第２扉体３Ｂには係合部１１を設け、前記開口部２の上側又は下側に沿って規制手段１２を設け、全ての扉体３，…が閉扉状態において前記施錠具９の施錠操作による連動手段１０の駆動に伴って前記規制手段１２が連動して前記係合部１１に係合し、第２扉体３Ｂの開扉動作を不能としてなるものである。ここで、前記框部８とは、開口部２の周縁部であって本体１に対して固定された部分を含む広い概念である。
【００１３】
更に詳しくは、前記連動手段１０が第１扉体３Ａの裏面側に上下動可能に設けた連動杆１０であって施錠具９の施錠操作に伴って上動するものであり、前記規制手段１２が中央部を上レール４Ａの近傍に奥行方向の支軸１３にて傾動可能に支持した規制杆１２であって一端部が前記連動杆１０の上端で押し上げられることにより他端部が押し下げられて第２扉体３Ｂの裏面側に突設した係合部１１を当止するものである。
【００１４】
図４は第１扉体３Ａを裏面側から示し、図５はその部分断面を示したものであり、閉扉時に本体１の框部８に当接する右端に設けた縦補強部材６に、ガイド金具１４，１４によって前記連動杆１０を上下動可能に取付けるとともに、該連動杆１０の下端は前記施錠具９の操作によって上下動する施錠杆１５に枢着又は固着している。そして、前記連動杆１０の上端部には、本体１の奥行方向内方へ水平片１０Ａを屈曲形成し、該水平片１０Ａの後端を上方へ立ち上げて断面逆Ｌ字状の垂直片１０Ｂを形成している。また、前記施錠具９及び連動杆１０は上部を除き、カバー部材１６で覆われている。尚、図中１７は引手である。
【００１５】
図６は第２扉体３Ｂを裏面側から示し、図７はその上部側面を示したものであり、閉扉時に本体１の框部８に当接する左側の上部には、前記係合部１１を裏面側に突設している。前記係合部１１は、第２扉体３Ｂに固着する固定片１１Ａと裏面側に突出した断面倒Ｌ字形の当止片１１Ｂとを有している。
【００１６】
前記規制杆１２は、前記上レール４Ａの裏面側に沿って配設する長尺部材であり、中央部を前記上レール４Ａを取付けるレール受部材１８にスペーサー１９を介して傾動可能に取付けている。前記スペーサー１９には、支軸１３が一体的に形成されており、該支軸１３を規制杆１２に形成した軸孔２０に挿通し、支軸１３を貫通させた止めネジ２１にて規制杆１２が外れないように取付けている。また、前記規制杆１２は、少なくとも一端部の下縁に前記連動杆１０の垂直片１０Ｂが当接する水平な当接片１２Ａを形成するとともに、他端部の下縁に前記係合部１１の当止片１１Ｂを確実に当止できるように水平な折曲片１２Ｂを形成している。尚、前記規制杆１２は断面Ｌ字形に形成し、下縁の水平部分を前記当接片１２Ａと折曲片１２Ｂとしても良い。
【００１７】
そして、前記各扉体３，…が閉扉状態で、前記第１扉体３Ａお施錠具９を施錠操作すると、その操作に連動して連動杆１０が上動し、該連動杆１０の垂直片１０Ｂで前記規制杆１２の一端部の当接片１２Ａを押し上げると、該規制杆１２が支軸１３を中心に傾動して、他端部のが押し下げられ、規制杆１２の端部及び折曲片１２Ｂで第２扉体３Ｂの係合部１１の当止片１１Ｂの開口部２中心側を当止し、該第２扉体３Ｂの開扉動作を不能とするのである。尚、前記規制杆１２は、単独部材でなくても、一端部が押し上げられると、それから離れた他端部が押し下げられる構造であれば、複数の部材を組み合わせた機構で置き換えることが可能である。
【００１８】
また、前記施錠具９と本体１の框部８とを係脱する構造は、例えば施錠具９の操作によって回動するラッチと框部８に形成した係合孔であっても良いが、構造を簡単にするために、本実施形態では、前記連動杆１０の垂直片１０Ｂが、施錠具９の施錠操作によって上動した場合に、図８に示すように前記レール受部材１８の切欠孔１８Ａ内に係合する構造を採用している。ここで、前記連動杆１０の垂直片１０Ｂは、前記レール受部材１８の切欠孔１８Ａを通って前記規制杆１２の当接片１２Ａを押し上げるのである。尚、前記切欠孔１８Ａは、レール受部材１８に形成する外に、上レール４Ａに形成することも可能であり、更には本体１の開口部２の框部８に、規制杆１２と並設して突設した部材で代用することも可能である。
【００１９】
また、施錠状態から解錠する場合には、前記施錠具９を解錠操作して連動杆１０を下動させれば、前記規制杆１２の当接片１２Ａ側の一端部が自重又は図示しない弾性付勢手段によって下がり、前記折曲片１２Ｂ側の他端部が上がって、前記第２扉体３Ｂの係合部１１の当止片１１Ｂが通過可能、即ち第２扉体３Ｂを開扉動作が可能となるのである。
【００２０】
最後に、前記ストッパー部材７を扉体３に取付ける構造を図１０及び図１１に基づいて説明する。前記扉体３の表面板２２の一側部には、ストッパー部材７の一部を受け入れる開口２３を形成するとともに、その下方に横長の係合孔２４を形成している。前記開口２３は、上半分に横幅が広い挿入開口２３Ａと、下半分に横幅が狭い係合開口２３Ｂとを連通形成したものである。前記ストッパー部材７は、硬質合成樹脂製のストッパー本体２５と、該ストッパー本体２５に嵌着する軟質合成樹脂製又は合成ゴム製の緩衝部材２６とから構成されている。前記ストッパー本体２５は、一部に前記開口２３の挿入開口２３Ａを通過可能且つ係合開口２３Ｂを通過不能な大きさ形状の取付部２５Ａと、該取付部２５Ａから突出した当止部２５Ｂとを一体形成するとともに、前記取付部２５Ａから下方に脚片２５Ｃを延設するとともに、該脚片２５Ｃの下端であって前記当止部２５Ｂを突設した側に爪部２５Ｄを形成したものである。また、前記緩衝部材２６は、内部が貫通した中空状であり、前記ストッパー本体２５の当止部２５Ｂに外嵌して取付けるものである。
【００２１】
そして、前記ストッパー本体２５の脚片２５Ｃから取付部２５Ａを、挿入開口２３Ａに挿入し、取付部２５Ａと脚片２５Ｃを表面板２２と縦補強部材６で形成される空間内に位置させ、その状態でストッパー本体２５を下方へ移動させて係合開口２３Ｂに位置させ、取付部２５Ａを該係合開口２３Ｂの両側縁に係止するとともに、脚片２５Ｃの爪部２５Ｄを前記係合孔２４に裏面側から無理嵌めし、ストッパー本体２５の上動を規制して取付ける。そして、ストッパー部材７を取付けた状態では、前記取付部２５Ａと緩衝部材２６とで係合開口２３Ｂの両側縁の表面板２２を挾持した状態となる。前記ストッパー部材７は、開扉時又は閉扉時に前側に位置する扉体３の両縦補強部材６，６の内側面に衝突するが、緩衝部材２６の存在によってその衝撃は和らげられ、また衝突音を発することもなくなる。
【００２２】
【発明の効果】
以上にしてなる本発明のキャビネットの多連扉装置は、左右何れかの端部に位置する扉体を開閉操作することによって、他の扉体が連動して開閉動作する構造の多連扉装置において、閉扉状態において左右一側端に位置する扉体に設けた施錠具を施錠操作することによって、同時に左右他側端の扉体の開扉動作を不能とすることができ、扉体の施錠操作を伴う開閉操作が非常に簡単になる。
