Description

【０００１】
【発明の属する技術分野】
本発明は、例えば、ノート型と称されるパソコンやワープロ、或いは携帯電話などにおける操作部を備えた本体部とディスプレイ部を備えた開閉蓋部とを起伏回動自在に枢着するために使用されるヒンジ装置に関するものである。
【０００２】
【従来の技術及び発明が解決しようとする課題】
例えば、折り畳みタイプの携帯電話は、中央のヒンジ装置を介して枢着される一側の第一部材にはディスプレイ部が設けられ、反対側の第二部材には操作部が設けられた構造となっており、この操作部とディスプレイ部とはヒンジ装置を介して電気的に接続されていて、操作部の操作がディスプレイ部に反映表示されるように構成されている。
【０００３】
従来、この種の折り畳み式携帯電話においては、一般的にディスプレイ部と操作部とを電気的に接続する接続線がヒンジ装置内を通る構成となっているが、携帯電話を開閉操作する度にヒンジ装置内でこの接続線が折れ曲がったり捩れたりするため、長期間使用していると接触不良を起こしたり、場合によっては接続線が断線したりするのではないかとの懸念がある。
【０００４】
本発明は、このような問題点に着目し、ヒンジ装置内に接続線を通すのではなく、ヒンジ装置を構成する部品自体に導電性を持たせる構成とすることで、従来のような不具合を生じる懸念を解消し、更に第一部材と第二部材とを枢着して成る電子機器の製作も容易となる画期的なヒンジ装置を提供するものである。
【０００５】
【課題を解決するための手段】
添付図面を参照して本発明の要旨を説明する。

電気的接続構造を備えた第一部材６と第二部材７とを枢着するヒンジ装置であって、導電性を有する軸部材１の一端側に前記第一部材６に取り付けられる第一取付部２を設け、軸部材１の他端側に前記第二部材７に取り付けられる第二取付部４を設け、この第一取付部２と第二取付部４とのいずれか一方若しくは双方を軸部材１に対し相対回動可能に設け、この第一取付部２に前記軸部材１と接触する第一導電部３を付設すると共にこの第一導電部３は前記第一取付部２の外部に露出状態に設けて、この第一取付部２を前記第一部材６の連結部に取り付けすると、この連結部に配線された第一部材６の前記電気的接続部に第一導電部３が接触するように構成し、前記第二取付部４に前記軸部材１と接触する第二導電部５を付設すると共にこの第二導電部５は前記第二取付部４の外部に露出状態に設けて、この第二取付部４を前記第二部材７の連結部に取り付けすると、この連結部に配線された第二部材７の前記電気的接続部に第二導電部５が接触するように構成し、この第二導電部５と前記第一導電部３とに前記軸部材１が嵌挿して接触する構成として第二導電部５と第一導電部３とが軸部材１を介して電気的に接続するように設け、前記第一部材６を第一取付部２に取り付けると共に前記第二部材７を第二取付部４に取り付けると、この第一部材６の電気的接続部と第二部材７の電気的接続部とが第一導電部３，軸部材１，第二導電部５を介して電気的に接続されるように構成したことを特徴とするヒンジ装置に係るものである。
【０００７】
また、前記軸部材１を導電性を有する素材で構成するか若しくは軸部材１に一端側から他端側にかけて導電材を付設して、前記第一導電部３と前記第二導電部５とがこの軸部材１を介して電気的に接続するように構成したことを特徴とする請求項１記載のヒンジ装置に係るものである。
【０００８】
また、前記第一取付部２にカム部11若しくはカム係合部12を設け、このカム部11若しくはカム係合部12に係合するカム係合部12若しくはカム部11を前記第二取付部４に設け、このカム部11，カム係合部12の少なくとも一方を係合離反方向にスライド移動自在に設けると共に、このカム部11，カム係合部12の少なくとも一方が係脱するに際して離反方向に移動した際係合方向に付勢する係合付勢機構13を設けて、この係合付勢機構13により前記カム部11とカム係合部12との係合は係脱せず回動ロック状態が保持されるように構成し、このカム部11，カム係合部12のいずれか一方を前記係合付勢機構13に抗して離反方向に移動させつつ回動させることで前記カム係合部12に対してカム部11を係脱させ、前記第一部材６に対して前記第二部材７を相対回動させるように構成したことを特徴とする請求項１，２のいずれか１項に記載のヒンジ装置に係るものである。

第一取付部２を第一部材６に取り付けると第一導電部３が第一部材６の電気的接続部に接触し、第二取付部４を第二部材７に取り付けると第二導電部５が第二部材７の電気的接続部に接触する。すると、この第二導電部５と前記第一導電部３とが軸部材１を介して電気的に接続しているため、第一部材６の電気的接続部と第二部材７の電気的接続部とが第一導電部３，軸部材１，第二導電部５を介して電気的に接続されることになる。
【００１１】
従って、本発明は、ヒンジ装置内に接続線を通す従来品とは異なり、ヒンジ装置自体に導電する構成であるから、接続線が断線したりするような懸念は全くなく、極めて耐久性に秀れると共に良好な電気的接続状態が維持されることになり、しかもヒンジ装置内に接続線を通すような作業は不要で、単に第一取付部２を第一部材６に取り付け、第二取付部４を第二部材７に取り付ける従来と同様のヒンジ取付作業を行うだけで第一部材６の電気的接続部と第二部材７の電気的接続部とが電通可能状態に接続されるため、電気的接続構造を備えた第一部材６と第二部材７とをヒンジ装置によって枢着して成る例えば携帯電話などの電子機器の製作も容易に行われることになるなど、極めて実用性に秀れた画期的なヒンジ装置となる。
【００１２】
また、例えば、前記第一導電部３は前記第一取付部２の外部に露出状態に設けて、この第一取付部２を前記第一部材６の連結部に取り付けすると、この連結部に配線された第一部材６の前記電気的接続部に第一導電部３が接触するように構成し、前記第二導電部５は前記第二取付部４の外部に露出状態に設けて、この第二取付部４を前記第二部材７の連結部に取り付けすると、この連結部に配線された第二部材７の前記電気的接続部に第二導電部５が接触するように構成すれば、前記作用効果を確実に発揮するヒンジ装置の構成を簡易に設計実現可能となり、一層実用的となる。
