Description

【０００１】
【発明の属する技術分野】
本発明は、音楽や映像を記録したコンパクトディスク（ＣＤ）、デジタルバーサタイルディスク（ＤＶＤ）等の円盤状記録媒体を収納するためのケースに関する。
【０００２】
【従来の技術】
従来の販売専用を目的とした収納ケースにおける円盤状記録媒体の着脱操作を行う保持部の例を図１４及び図１５に示す。その合成樹脂製保持部ａは、円盤状記録媒体の固定用穴を係止するための頭部ｃを側方から見てブリッジ形に形成して両端の支持部を一対の第１ヒンジｄを介してベースｂに夫々連接すると共に、頭部ｃの押圧部ｅの中央に第２ヒンジｆを設け、その押圧部ｅを指で押すことにより、ほぼ７０°〜９０°の角度のＶ字形に折曲させて記録媒体が頭部ｃから外れるように構成されている。ｇは記録媒体の固定用穴の周縁部下面を受けるべく頭部ｃに一体に形成された支持部である。そして、頭部ｃが押し込まれた状態において記録媒体の固定用穴を頭部ｃに合わせて押圧したときには、支持部ｇの梃子作用により頭部ｃを元の突出した状態に復元させて同記録媒体が固定されるように設けられている。
【０００３】
また、販売用とレンタルショップにおける展示用を兼ねたコンパクトな合成樹脂製収納ケースの一例を図１６に示す。この収納ケースｉは、円盤状記録媒体を箱型形状の本体ｊの正面側と上面側から出し入れできるように正面の扉ｔと上面の蓋体ｑを夫々開閉自由に設けると共に、円盤状記録媒体を着脱自由とする保持部ｎを本体ｊの背部に設け、扉ｔの内面下部にストッパーｕを設けたものがある。
【０００４】
その保持部ｎは、円盤状記録媒体の固定用穴を嵌める円弧形立上片ｏを等角度間隔で４カ所に配置し、中央の円形部ｐとそれら円弧形立上片ｏとを直線的に連結した形態とされている。その蓋体ｑについては、端部ｒを本体ｊの右側片ｋに形成された係合溝ｅと中央側片ｖの上端に形成された突片ｗに夫々係合させることにより上面開口ｘが閉じられた状態に保持され、内方に回転させた蓋体ｑの突起ｓを本体ｊに穿設された係合孔ｍに嵌合させることにより上面が開かれた状態に保持されるように設けられている。
【０００５】
図１７に示すように、この収納ケースｉは、円盤状記録媒体を本体ｊから取り出すと共に蓋体ｑを内方に折り曲げて扉ｔを閉じた状態としてから、記録媒体を格納する別に用意した公知のレンタル用ケースｙを上面開口ｘから本体内に挿入したとき、そのレンタル用ケースｙの底部がストッパーｕに当接することにより、同ケースの上部を上面開口ｘから所定高さまで露出させるように設けられ、その状態にて展示に利用することができる構造とされている。
【０００６】
【発明が解決しようとする課題】
従来の前者の保持部ａにおいては、押圧部ｅを指で押したときにＶ字形に折曲変形するために、その部分に指が挟まれる状態となって操作性に難点がある。加えて、収納ケースと一体成形を行うことができないので、製造コストが高くならざるを得ない。
【０００７】
また、後者の収納ケースｉにおいては、円形部ｐを指で押したときに保持部ｎの半径方向の変形収縮量が少ないことから、円盤状記録媒体が小さな力では簡単に外れなく、操作性がよくないと言える。また、内方に折り曲げた蓋体ｑを固定する構造が貧弱であって蓋体ｑの一部が浮き上がることもあり、実用性に甚だ欠けるという問題があった。
【０００８】
この発明の目的は、円盤状記録媒体の着脱が円滑に行える保持部を備えた収納ケースを提供することにある。
【０００９】
【課題を解決するための手段】
前記目的を達成するために請求項１に記載の発明は、コンパクトディスク等の円盤状記録媒体を箱型形状の本体の正面側から出し入れできるように正面の扉を開閉自由に設けると共に、円盤状記録媒体を着脱自由とする保持部を該本体の背部に設けた円盤状記録媒体の収納ケースであって、前記保持部については、中央の押圧部の仮想中心を中心として等角度で放射方向に延びる仮想線を挟むように左右一対の脚片を夫々配置し、各脚片はその仮想線と直交する線上に配置された第１ヒンジにより一端を前記背部に連接されると共に、他端の薄肉に形成された第２ヒンジにより前記押圧部の側壁片に夫々連接され、さらに前記一対の脚片に、円盤状記録媒体の固定用穴を係止させるための係合溝が形成された環形片を前記押圧部の周囲に夫々配設すると共にその固定用穴の周縁部下面に対応する突き上げ部を一体に形成してなり、円盤状記録媒体の固定用穴を該環形片に合わせて押圧することにより同記録媒体が固定され、他方、円盤状記録媒体が固定された保持部の押圧部を押圧することにより、環形片を第１ヒンジ及び第２ヒンジ部分の歪み弾性作用により仮想中心側に変位させつつ沈ませると同時に、前記突き上げ部にて円盤状記録媒体の周縁部の下降を抑制して同記録媒体の固定状態が解放されるように構成したことを特徴とする。

【００１１】
同様の目的を達成するために請求項３に記載の発明は、請求項１に記載の円盤状記録媒体の収納ケースにおいて、前記保持部については、中央の押圧部の仮想中心を中心として等角度で放射方向に延びる仮想線を挟むように左右一対の脚片を夫々配置し、各脚片はその仮想線と直交する線上に配置された第１ヒンジによりその一端を前記背部の前記仮想線と同じ方向に弾性変形可能な連結片に連接されると共に、他端の薄肉に形成された第２ヒンジにより前記押圧部の側壁片に夫々連接され、さらに前記一対の脚片に、円盤状記録媒体の固定用穴を係止させるための係合溝が形成された環形片を前記押圧部の周囲に夫々配設すると共にその固定用穴の周縁部下面に対応する突き上げ部を一体に形成したことを特徴とする。
【００１２】

【００１５】
同様の目的を達成するために請求項７に記載の発明は、請求項１、３、５の何れかに記載の円盤状記録媒体の収納ケースにおいて、前記保持部の押圧部を大きいストロークにて押圧することにより、該押圧部及び前記環形片が前記背部の開口部内に小嵩に格納されるように設けたことを特徴とする。
【００１６】
同様の目的を達成するために請求項８に記載の発明は、請求項１、３、５、７の何れかに記載の円盤状記録媒体の収納ケースにおいて、前記第１ヒンジを形成した脚片を中央部に設け、その脚片の両側に前記突き上げ部を左右対称に配設したことを特徴とする。
【００１７】
同様の目的を達成するために請求項９に記載の発明は、請求項１〜８の何れかに記載した販売専用の円盤状記録媒体の収納ケースにおいて、前記扉の内面にストッパー部を一体に形成し、その扉を閉じた状態において、そのストッパー部が前記押圧部と環形片との間に形成される凹溝に嵌合することにより前記保持部の無用な出没動作を規制するように設けたことを特徴とする。
【００１８】
【発明の作用及び効果】
（請求項１及び請求項２の発明）
円盤状記録媒体の固定用穴を保持部の環形片に合わせて押圧すると、環形片は第１ヒンジ及び第２ヒンジ部分の歪み弾性変形作用により仮想中心側に変位しつつ沈んでその固定用穴を通過させ、これとほぼ同時に、その歪み弾性変形作用によって元の位置に戻る。しかして、環形片の係合溝に固定用穴が係止されて円盤状記録媒体は固定される。
【００１９】
また、請求項１の発明において、円盤状記録媒体が固定された保持部の押圧部を指で押圧した場合には、円盤状記録媒体は環形片と一緒に少し下降するが、固定用穴の周縁部の下面が突き上げ部に当接してそれ以上の下降を抑制されるため、環形片（及び押圧部）のみがさらに下降して固定用穴が係合溝から外れる。
【００２０】
上記収納ケースによれば、環形片が第１ヒンジ及び第２ヒンジ部分の歪み弾性変形と脚片の傾動の相乗作用により円滑に出没作動するため、円盤状記録媒体の着脱操作が行い易い。
【００２１】
（請求項３及び請求項４の発明）
円盤状記録媒体の固定用穴を保持部の環形片に合わせて押圧すると、環形片は本体側に設けた連結片の弾性変形により仮想中心側に変位しつつ沈んでその固定用穴を通過させ、これとほぼ同時に、その連結片の弾性変形作用によって元の状態に戻る。しかして、環形片の係合溝に固定用穴が係止されて円盤状記録媒体は固定される。
【００２２】
また、円盤状記録媒体が固定された保持部の押圧部を指で押圧した場合には、環形片は本体側の連結片の弾性変形により仮想中心側に変位しつつ第１ヒンジを支点とする傾動作用により沈んで、その固定用穴をくぐる。その押圧を止めると環形片は連結片の弾性変形作用により元の位置に戻り、固定用穴が係合溝から外れる。
【００２３】
上記収納ケースによれば、環形片が連結片の弾性変形による変位と、第１ヒンジ及び第２ヒンジを有する脚片の傾動の相乗作用により円滑に出没作動するので、円盤状記録媒体の着脱操作が大変行い易い。
【００２４】
（請求項５及び請求項６の発明）
円盤状記録媒体の固定用穴を保持部の環形片に合わせて押圧すると、環形片は脚片の弾性変形による収縮作用により仮想中心側に変位しつつ沈んでその固定用穴を通過させ、これとほぼ同時に、その脚片の弾性変形による伸長作用によって元の位置に戻る。しかして、環形片の係合溝に固定用穴が係止されて円盤状記録媒体は固定される。
【００２５】
また、円盤状記録媒体が固定された押圧部を指で押圧した場合には、環形片は脚片の弾性変形による収縮作用により仮想中心側に変位しつつ第１ヒンジを支点とする傾動作用により沈んで、その固定用穴をくぐる。その押圧を止めると環形片はその脚片の弾性変形による伸長作用により元の位置に戻り、固定用穴が係合溝から外れる。
【００２６】
上記収納ケースによれば、環形片が脚片の弾性変形による伸縮と、第１ヒンジ及び第２ヒンジを有する脚片の傾動の相乗作用により円滑に出没作動するので、円盤状記録媒体の着脱操作が大変行い易い。
【００２７】
なお、請求項１、３、５の発明における環形片（及び押圧部）が開口部内に押し込まれた状態において、円盤状記録媒体を保持部にセットして同記録媒体の固定用穴の周縁部を押圧したときには、跳ね上がった突き上げ部が後方へ押されて環形片（及び押圧部）を外に飛び出させる。このため、環形片の係合溝に固定用穴が係止されて円盤状記録媒体は固定される。
【００２８】
（請求項７の発明）
保持部の押圧部を大きいストロークにて押圧すると、脚片は第２ヒンジが開口部に進入するまで第１ヒンジを支点として回転し、押圧部及び環形片は記録媒体の固定を解いた位置からさらに沈んで開口部内に小嵩に格納される。
【００２９】
販売用とレンタルショップにおける展示用とを兼ねた収納ケースの場合においては、保持部を不使用時に小嵩に格納することができるので特に有効である。すなわち、円盤状記録媒体を格納するレンタル用ケースを収めた場合、収納ケースの厚さは余り大きくならず、レンタル用ケースが奥深く挿入される構造であるため展示態様における形態についてもコンパクトになり、陳列時の省スペース化に役立つ。
【００３０】
（請求項８の発明）
円盤状記録媒体の固定作用については、上記各請求項の発明に述べた内容に準ずる。
【００３１】
（請求項９の発明）
扉を閉じた状態において、ストッパー部が押圧部と環形片との間の凹溝に嵌合して保持部の無用な出没動作を規制する。しかして、収納ケースの取り扱い又は輸送時に保持部が何らかの外力により動作することにより、固定された円盤状記録媒体が外れてしまうという事態を未然に防止することができる。この発明の収納ケースは、販売専用ケースに適用される。
【００３２】
【発明の実施の形態】
以下に、本発明の実施の形態例を図面に基づいて説明する。図１から図６は第１実施の形態例、図７から図９は第２実施の形態例、図１０から図１２は第３実施の形態例、図１３は第４実施の形態例にかかるものであって、図１は収納ケースの扉を開いた状態を示す正面図、図２は保持部の正面図、図３は図２の要部の断面図、図４は図３に示す保持部が押し込まれて格納された状態を示す説明図、図５はロック片の正面図、図６は蓋体をロック片によりロックを施した状態を示す説明図、図７は保持部の正面図、図８は図７の要部の断面図、図９は図８に示す保持部が押し込まれて格納された状態を示す説明図、図１０は保持部の正面図、図１１は図１０の要部の断面図、図１２は図１１に示す保持部が押し込まれて格納された状態を示す説明図、図１３は保持部の正面図である。
【００３３】
（第１実施の形態例）
図１に示す請求項１の発明に係る第１実施の形態例の円盤状記録媒体の収納ケースＣは、箱型形状の本体１と扉２１及び上面の蓋体２５とを合成樹脂材料により一体成形されている。
その本体１には、長方形の背部２の中央下方にコンパクトディスク等の円盤状記録媒体（１）の固定用穴（２）を嵌着させるための保持部５を設け、その背部２に右側片２ａと底片２ｂとが一体に形成されている。３は円盤状記録媒体（１）の外周縁部を支持するための円弧状突部であり、背部２に一体に形成されている。
【００３４】
その保持部５については、図２及び図３に示すように、本体１の背部２の中央に配置された円形座部２ｃに形成した開口部４の中央に、ほぼ三角形の押圧部１０の仮想中心（イ）を中心として等角度、この例では１２０°間隔で放射方向に延びる仮想線（ロ）を挟むように左右一対の脚片７、７を３カ所に配置している。図３に示すように、各脚片７は、その仮想線（ロ）と直交する線（ハ）上に配置された第１ヒンジ６により一端７ａを前記開口部４の内端に連接されると共に、その他端７ｂの薄肉に形成された第２ヒンジ８によって押圧部１０の側壁片１１の下端１１ａに夫々連接されている。
【００３５】
なお、第１ヒンジ６と第２ヒンジ８を結ぶ直線と背部２とのなす脚片７の仰角については、２５°〜３.５°の範囲とするが、好ましくは１５°〜５°の範囲とする。
【００３６】
１３は円盤状記録媒体（１）の固定用穴（２）を係止させるための係合溝１５が形成された環形片である。その環形片１３は押圧部１０の周囲に配置されており、第２ヒンジ８から外方に形成された凹溝１２を介して一対の脚片７、７に一体に設けられている。９は左右一対の脚片７、７の後部に差し渡すように一体に形成された突き上げ部であって、各突き上げ部９は、固定用穴（２）の周縁部下面に対応するように設けられている。
【００３７】
上記本体１の左側縁には、薄肉に形成したヒンジ１７により中央側片１８の一側縁を連接する。１９は中央側片１８の上端内方に少し突出するように設けた係止部である。その中央側片１８の他側縁には、薄肉に形成したヒンジ２０により正面の扉２１を一体状に連接して同扉２１を開閉可能に設ける。この扉２１は、上方を開放して右側片２１ａと底片２１ｂが一体に形成されている。
【００３８】
なお、販売専用の収納ケースについては、扉２１の内面にほぼ三角形の各辺に相当する位置にストッパー部（図示せず）を一体に形成するのが好ましい。そして、扉２１を閉じた状態において、そのストッパー部が押圧部１０と環形片１３との間に形成される凹溝１２に嵌合することにより保持部５の無用な出没動作を規制するように設ける。
【００３９】
なお、保持部が上記保持部５以外のものであって、押圧部と環形片との間に凹溝を形成して押圧部の出没動作により円盤状記録媒体を着脱する構造のものについては、上記ストッパー部に準ずる構成を適用することが可能である。
【００４０】
２５は前記背部２の上縁部に薄肉に形成されたヒンジ２４により一体状に連接された蓋体であって、前記背部２、右側片２ａ、中央側片１８と扉２１により四方を囲まれて形成される上面開口２３を開閉するためのものである。図５及び図６に示すように、蓋体２５は自由端部に突条２６を設けると共に端部２５ａ、２５ｂを少し薄く設けられている。そして、蓋体２５の一方の端部２５ａを右側片２ａの上端内方に設けた係止溝２ｄに係合させると共に、扉２１を閉めたときに他方の端部２５ｂを前記係止部１９に係合させることにより、上面開口２３が閉じられた状態に保持されるように設ける。
【００４１】
３０は前記ヒンジ２４から少し内方位置の背部２に設けられた一対のロック片である。このロック片３０の押え部３１は背部２から切り離して設けられ、その押え部３１から両側方に延びる突部３２の一端には係止爪３３を夫々形成すると共に、他端をバネの機能を持つ弾性変形可能な連結片３４を介して背部２に連接する。しかして、押え部３１を指で押し又は離すことによりロック片３０を本体１の厚さ方向にシーソー動作可能に設ける。そして、内方に回転させた蓋体２５の突条２６を各ロック片３０の係止爪３３に夫々係合させることにより、上面開口２３が開かれた状態に保持するように設ける。
【００４２】
なお、上述したロック片３０による蓋体２５のロック構造については、レンタルショップにおける展示用ケースとして利用される蓋体付の収納ケースであれば、円盤状記録媒体又はビデオカセットを対象とする他の収納ケースにも適用することが可能である。
【００４３】
また、隣り合う脚片７、７の間に位置する部分２ｅについては、円盤状記録媒体（１）を円形座部２ｃから離れる方向に付勢する片持ち式の弾性支持片とするように設けることも可能である。しかして、前記保持部５の押圧部１０が押し込まれるときに、その弾性支持片の自由端部を円盤状記録媒体（１）の非記録部に当接させて同記録媒体（１）が沈むのを抑制することにより、着脱操作を円滑に行わせることができる。この弾性支持片については前記突き上げ部９のない構造の保持部に特に有効である。なお、後述する第２、第３実施形態例の収納ケースにも適用することができる。
【００４４】
次に、上記構成になる収納ケースＣの作動、取り扱い方について説明する。
１．円盤状記録媒体（１）の固定用穴（２）を保持部５の環形片１３に合わせて押圧部１０を押圧すると、環形片１３は第１ヒンジ６及び第２ヒンジ８部分の歪み弾性変形作用により仮想中心（イ）側に変位しつつ沈んでその固定用穴（２）を通過させる。これとほぼ同時に、環形片１３が歪み弾性変形作用によって元の位置に戻るため、円盤状記録媒体（１）は係合溝１５に固定用穴（２）を係止される。
２．円盤状記録媒体（１）が固定された保持部５の押圧部１０を指で押圧すると、環形片１３は第１ヒンジ６及び第２ヒンジ８部分の歪み弾性変形及び第１ヒンジ６を支点とする傾動作用により沈んで、同記録媒体の固定用穴（２）をくぐる。円盤状記録媒体（１）の中央部分は環形片１３と一緒に少し下降するが、固定用穴（２）の周縁部の下面が突き上げ部９に当接してそれ以上の下降が抑制されるため、環形片１３がさらに下降して固定用穴（２）から外れて固定状態を解放する。
３．また、保持部５の押圧部１０を強く大きいストロークにて押圧すると、脚片７は第１ヒンジ６を支点として回転し、図４に示すように、押圧部１０及び環形片１３が円盤状記録媒体（１）の固定を解いた位置からさらに沈んで開口部４に小嵩に格納される。
【００４５】
（第２実施の形態例）
請求項３の発明に係る第２実施の形態例の収納ケースは、円盤状記録媒体（１）を着脱自由とする保持部１０５以外の構成については、前記第１実施の形態例である収納ケースＣと全く同じであることから、保持部１０５の構成についてのみ詳しく説明する。
【００４６】
図７に示すように、保持部１０５は、円形座部１０２ｃに形成した開口部１０４の中央に、ほぼ三角形の押圧部１１０の仮想中心（イ）を中心として等角度、この例では１２０°間隔で放射方向に延びる仮想線（ロ）を挟むように左右一対の脚片１０７、１０７を３カ所に配置している。図８に示すように、各脚片１０７は、その仮想線（ロ）と直交する線（ハ）上に配置された第１ヒンジ１０６により一端１０７ａを収納ケースの背部１０２に設けた仮想線（ロ）と同じ方向に弾性変形可能な連結片１１６に連接されると共に、その他端１０７ｂの薄肉に形成された第２ヒンジ１０８によって押圧部１１０の側壁片１１１の下端１１１ａに夫々連接されている。
【００４７】
１１３は円盤状記録媒体（１）の固定用穴（２）を係止させるための係合溝１１５が形成された環形片である。その環形片１１３は、第２ヒンジ１０８から外方に形成された凹溝１１２を介して一対の脚片１０７、１０７に夫々配設されている。１０９は左右一対の脚片１０７、１０７の後部に差し渡すように一体に形成された突き上げ部である。これらの突き上げ部１０９は、固定用穴（２）の周縁部下面に対応するように設けられている。
【００４８】
かかる構成になる保持部１０５の作用については、前述した請求項３の発明の項に記載した内容と同じであるので説明を省く。
【００４９】
（第３実施の形態例）
請求項５の発明に係る第３実施の形態例の収納ケースは、円盤状記録媒体（１）を着脱自由とする保持部２０５以外の構成については、前記第１実施の形態例である収納ケースＣと全く同じであることから、保持部２０５の構成についてのみ詳しく説明する。
【００５０】
図１０に示すように、保持部２０５は、円形座部２０２ｃに形成した開口部２０４の中央に、ほぼ三角形の押圧部２１０の仮想中心（イ）を中心として等角度、この例では１２０°間隔で放射方向に延びる仮想線（ロ）を挟むように左右一対の脚片２０７、２０７を３カ所に配置している。図１１に示すように、各脚片２０７は、その仮想線（ロ）と直交する線（ハ）上に配置された第１ヒンジ２０６により一端の連結片２０７ａを前記開口部２０４の内端に連接されると共に、その他端の連結片２０７ｂの薄肉に形成された第２ヒンジ２０８によって押圧部２１０の側壁片２１１の下端２１１ａに夫々連接されている。各々の脚片２０７は、仮想線（ロ）と同じ方向に弾性変形可能な連結片２０７ａ及び連結片２０７ｂを設けることにより伸縮可能に設けられている。
【００５１】
２１３は円盤状記録媒体（１）の固定用穴（２）を係止させるための係合溝２１５が形成された環形片である。その環形片２１３は、第２ヒンジ２０８から外方に形成された凹溝２１２を介して一対の脚片２０７、２０７に夫々配設されている。２０９は左右一対の脚片２０７、２０７の後部に差し渡すように一体に形成された突き上げ部であって、これらの突き上げ部２０９は、固定用穴（２）の周縁部下面に対応するように設けられている。
【００５２】
かかる構成になる保持部２０５の作用については、前述した請求項５の発明の項に記載した内容と同じであるので説明を省く。
【００５３】
（第４実施の形態例）
請求項８の発明に係る第４実施の形態例の収納ケースは、円盤状記録媒体（１）を着脱自由とする保持部３０５以外の構成については、前記第１実施の形態例である収納ケースＣと全く同じである。また、保持部３０５については、図１３に示すように、第２実施の形態例の保持部１０５の構成に対して、第１ヒンジ３０６を形成した脚片３０７を中央部に設け、突き上げ部３０９をその脚片３０７の両側に左右対称に配設した構成である。よって、それと同一構成部分については、保持部１０５の説明に用いた符号に対応する符号（三百番台）を図面に記載して説明を省略する。
【００５４】
なお、この収納ケースにおける脚片３０７、３０７の間に位置する部分３０２ｅについては、上記段落「００４３」で説明した弾性支持片と同様の構成を適用することも可能である。
