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。

【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
