【0015】
【作用】
この発明においては、運搬時に本体と蓋体とが閉じた状態で取手を持ち上げると、係止部材が磁石保持手段による磁力によって係止方向に移動して、本体と蓋体とを係止状態とし、運搬後の取手部の復帰によって係止部材を非係止方向に移動させる。
【0016】
【実施例】
参考例1
後述する実施例1の前提説明となる参考例1に係わる可搬式電子機器のロック装置は、キーボードスイッチ入力部を有する本体に表示器を備えた表示部からなる蓋体が回転自在に取付けられ、収納時に本体と表示部が閉じて一体となるパソコンや制御機器の可搬形プログラミング装置において、取手の取付部が水平方向に可動自在な取手を備え、可搬時に本体と表示部を閉じた状態で取手を持ち上げると、取手の取付部が水平方向に移動することにより表示部と本体が係合し、閉じた状態に保持する機構を備えたものである。
【0017】
参考例1を図1〜図4により説明する。図中、従来例と同じ符号で示されたものはそれと同一もしくは同等なものを示す。図1はパソコンや制御機器の可搬形プログラミング装置の構成を示す使用時の斜視図、図2は本体の取手取付部の断面図、図3は本体と表示部からなる蓋体を閉じた状態で取手を持ち上げる前の取付部正面断面図、図4は取手を持ち上げた取付部断面図である。

【0021】
参考例2を図5、図6により説明する。図中、従来例および参考例1と同じ符号で示されたものは従来例および実施例1のそれと同一もしくは同等なものを示す。図5は本体と表示部を閉じた状態で取手を持ち上げる前の取付け部横断面図、図6は取手を持ち上げた時の取付け部横断面図である。図5、図6において、3eはコ字形の芯材、3cは芯材3eに設けられた保持レバー9からなる係止部材との連結穴、7aは芯材3eを垂直方向に可動自在に固定するリティナである。
【0022】
次に作用について説明する。本体1と表示部4を閉じた状態で取手3aを持ち上げると、垂直方向に可動自在な芯材3eが上方(外側)にスライドする。そして、芯材3eの連結穴3cにピン10で連結された保持レバー9が回転し、それの爪部が表示部の連結穴4aに係合して、表示部4は閉じた状態に保持される。次に、可搬後取手3aを重力または手で押して本体1に格納すると、芯材が内側へスライドするため連結された保持レバー9は逆回転し、表示部の係合穴4aから爪部が外れ本体1に格納される。
【0023】
参考例2によれば、構成部品点数が少なく取手の芯材に弾性体を使用する必要がなく実施例1に比べ製作コストを安くできる。また、可搬時に本体と表示部分を閉じた状態で取手を持ち上げると、本体に取り付けられた取手と連結または連係する保持レバーの爪部が表示部と本体と表示部の重力により自動的に係合保持するので、可搬時に表示部開閉レバーに手(指)等が触れても表示部が開くという危険を防止でき、操作性、安全性が向上する効果がある。

実施例1
実施例1に係わる可搬式電子機器のロック装置は、参考例1または参考例2のパソコンや制御機器の可搬式電子機器のロック装置において、取手部と係合する磁石を有し、運搬時に本体と表示部を閉じた状態で取手部を持ち上げると、磁石の力により表示部と本体を係合し、閉じた状態に保持する機構を備えたものである。
【0025】
実施例1図7図8により説明する。図中、従来例、参考例1,2と同じ符号で示されたものは従来例、参考例1,2のそれと同一もしくは同等なものを示す。図7は本体と表示部を閉じた状態で取手部を持ち上げる前の取手部取付部分の横断面図、図8は取手部を持ち上げた時の取手部取付部分の横断面図である。図7図8において、9bは一端部に蓋体を構成する表示部4の係合穴4aと係合する爪部を備え、本体1に回動自在に取り付けられた吸磁される金属の保持レバーからなる係止部材、14は取手のグリップ3aとともに取手部を構成する芯材3eに取り付けられた円弧面を有する永久磁石である。保持レバー9aおよび磁石14は磁石保持手段を構成する。
保持レバー9bからなる係止部材は、図7および図8に示すように、その他端部を磁石14の円弧面に接して磁石14に吸着されている。
【0026】
次に作用について説明する。図7に示す取手部による本体1と表示部4からなる蓋体の吊り下げ運搬時に本体1と表示部4からなる蓋体を閉じた状態でコ字形の芯材3eとともに取手部を構成する取手のグリップ3aを持ち上げると、垂直方向に可動自在な芯材3eが上方(外側)[図示左方向]にスライドし、それに取り付けられた磁石14もスライドする。そして保持レバー9bはその他端部を磁石14の円弧面に接した状態で磁石14の吸引力により反時計式に回動し、保持レバー9bの爪部が表示部4の係合穴4aに係合して表示部4は閉じた状態に保持される。次に運搬動作終了後取手のグリップ3aを重力または手で押して本体1に格納すると、保持レバー9bは芯材3eに押されて時計式に逆回転し、表示部4の係合穴4aから爪部が外れ本体1に格納される。
【0027】
実施例1によれば、構成部品点数が少なくばねが不要で保持レバー9bと芯材3eは磁力により自動的に連接するため、組立が極めて容易であり、実施例3に比べ製作コストを安くできる。また可搬時に本体1と表示部4を閉じた状態で取手のグリップ3aを持ち上げると、本体1に取り付けられた取手のグリップ3aと連結または連係する保持レバー9bの爪部が表示部4と磁力により自動的に係合保持するので、可搬時に表示部開閉レバーに手(指)等が触れても表示部4が開くという危険を防止でき、操作性、安全性が向上する効果がある。
【0028】
【発明の効果】
この発明によれば、吊り下げ運搬の際の蓋体の回動を、吊り下げ運搬時の取手の動きに関連して係止部材に磁石による駆動力を作用させることにより、有効かつ確実に防止することができる。係止部材は磁石による駆動力により作動されるため、その動作が的確であるばかりでなく、機械的連結を省略することが可能となる。
