Description

【０００１】
【発明の属する技術分野】
本発明は、ヒンジ装置並びにヒンジ装置を用いた携帯電話，モバイル等の電子機器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】
例えば従来の折り畳み式の携帯電話は、数字キーやファンクションキーを配列した操作部を下側となる本体部の上面側に設け、この操作部のキー操作等により所定の表示がなされる液晶パネルなどのディスプレイ部を上側となる重合部の伏面側（重合側）に設け、この本体部と重合部とをヒンジ装置を介して連結して、本体部と重合部とを二つ折り重合して操作部を重合部により隠蔽した折り畳み閉塞状態から、ヒンジ装置により重合部を起伏回動して反転し、操作部とディスプレイ部とが露出した開放状態に切り替えできるように構成している。
【０００３】
そのため、従来のこのような起伏回動する重合部で本体部の操作部を覆う電子機器においては、折り畳み重合してコンパクト化できるものの操作部を隠蔽した重合状態ではディスプレイ部も隠蔽してしまう構造となり、コンパクト化した状態での使用が制限されざるを得なく不便である場合も多い。
【０００４】
また、操作部を操作する場合には、ディスプレイ部を設けた重い重合部を立ち起こし反転回動させなければならず、この開閉動作（特に開放動作）させずらい欠点もある。
【０００５】
そこで、起伏回動により開閉動作するのではなく、重合面に沿って略水平方向に重合部を回動して開閉動作するように構成し、例えば不使用時あるいはキー操作を不要にして折り畳んだ際においても、言い換えるとたとえディスプレイ部を設けた重合部を本体部に重合して操作部を隠蔽したコンパクト化状態においても、ディスプレイ部が上側に配設され、ディスプレイ部を視認したり、機能させたりすることが可能となり、また重合してコンパクト化した状態から操作部及びディスプレイ部を露出して本体部と重合部とを連設した状態に切り替える場合は、重合面に沿って略水平方向に重合部を回動することで行えるため、この開放動作も容易に行え、機器装置として使用用途が広がり、しかも前記開閉動作も容易となる携帯電話，モバイル等の電子機器が提案されている。
【０００６】
本発明はこのような水平回動タイプの電子機器を実現するために試行錯誤を重ね、これを容易に実現できるヒンジ装置並びにヒンジ装置を用いた電子機器を提供することを目的としたもので、しかもこの開閉回動が可能となるように容易に製作できる上、この開閉回動が常にスムーズに行え、耐久性にも秀れた画期的なヒンジ装置並びにヒンジ装置を用いた電子機器を提供することを目的としている。
【０００７】
【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。
【０００８】
第一部材２と第二部材４とを重合した状態から、前記第二部材４を相対的に重合面に対して略平行に回動して重合面を露出させることができるように枢着するヒンジ装置であって、前記第一部材２若しくは前記第二部材４の一方の部材に取付孔６を設けた第一の取付ベース５を設け、他方の部材に前記取付孔６に貫通して係合する回動軸部８を有する第二の取付ベース７を設け、前記回動軸部８が前記取付孔６に対して回動することで、前記第一部材２に対して前記第二部材４が相対的に回動し得るように構成し、前記第一の取付ベース５は、折り返したＵ状部材で形成され、この折り返し一側部に前記取付孔６を設けて、前記回動軸部８を所定角度で貫通するように設定し、この回動軸部８に負荷がかかった際、前記折り返し構造によりこの負荷を弾圧吸収し得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。
【０００９】
また、前記取付孔６に係合する前記回動軸部８に弾性体９により所定部分に圧接する圧接部10を設けて前記第一部材２に対する前記第二部材４の相対回動に際して回動抵抗が生じ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。
【００１０】
また、前記回動軸部８の回動を所定位置で位置決め係止する位置決め係止機構11を設けて、前記第二部材４が少なくとも前記第一部材２を覆うように重合する位置と、第一部材２と直線状に連設状態となる位置で位置決め係止され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。
【００１１】
また、操作部１を設けた本体部２と、ディスプレイ部３を設けた重合部４と、前記操作部１を操作しない時にはこの操作部１を覆うように重合配設し得るように前記本体部２と前記重合部４とを連結するヒンジ装置を有し、このヒンジ装置は、前記本体部２若しくは前記重合部４の一方の部材に設けられ、取付孔６を有する第一の取付ベース５と、他方の部材に設けられ、前記取付孔６に貫通して係合する回動軸部８を有する第二の取付ベース７とを有し、前記回動軸部８が前記取付孔６に対して回動することで、前記本体部２に対して前記重合部４が相対的に回動し得るように構成し、前記第一の取付ベース５は、折り返したＵ状部材で形成され、この折り返し一側部に前記取付孔６を設けて、前記回動軸部８を所定角度で貫通し係合するように設定し、この回動軸部８に負荷がかかった際、前記折り返し構造によりこの負荷を弾圧吸収し得るように構成したことを特徴とするヒンジ装置を用いた電子機器に係るものである。
【００１２】
【発明の実施の形態】
好適と考える本発明の実施の形態（発明をどのように実施するか）を、図面に基づいてその作用効果を示して簡単に説明する。
【００１３】
例えば第一部材２に第一の取付ベース５を設け、第二部材４に第二の取付ベース７を設け、第一の取付ベース５に設けた取付孔６に、第二の取付ベース７に設けた回動軸部８を貫通係合して第一部材２と第二部材４とを連結することで、このヒンジ装置によって、第一部材２と第二部材４とが重合した状態から、前記第二部材４を相対的に重合面に対して略平行に回動し重合面を露出させることができる。
【００１４】
しかも、前記第一の取付ベース５は、Ｕ状部材で構成され、このＵ状部材の折り返し一側部に設けた前記取付孔６の向きはこの折り返し度合や折り返し弾性度合によって調整可能となるため、第二部材４が第一部材２に重合した状態から重合面に沿って開閉回動できるように、取付孔６に貫通係合する回動軸部８の取付角度を適切に設定することが容易に行える。
【００１５】
また、更にこの第一の取付ベース５は、Ｕ状部材で形成されて折り返し構造となっているため、この第一の取付ベース５の取付孔６に係合した回動軸部８に負荷が加わってもこれを弾圧吸収でき、常にスムーズな回動操作が行え、耐久性も飛躍的に向上する。
【００１６】
従って、例えば第一部材２を操作部１を設けた本体部２とし、第二部材４をディスプレイ部３を設けた重合部４とすれば、このヒンジ装置Ｈにより端部同志を重合して連結することで、本体部２に対して重合部４を略水平方向に回動自在に連結でき、前記操作部１を操作しない時にはコンパクト化するため、この操作部１を覆うように本体部２と重合部４とを上下に重合配設し、また、このコンパクト化された重合状態では、ディスプレイ部３は重合部４の上面側に配されているため、操作部１は操作できないにしてもディスプレイ部３を視認することができ、またディスプレイ部３を機能させるように構成すれば、例えば予め操作部１により設定するなどした日付やカレンダー表示をさせたり、またデータ通信表示（携帯電話では例えば着信表示など）を行うようにしたりすれば、ディスプレイ部３は視認できるため様々な使用が可能となり、使用用途が広がったり、機能性が向上し、非常に便利となり実用性（商品価値）が高まる。
【００１７】
また、前記操作部１を操作するに際して前記重合部４を起伏回動させて前記操作部１を露出させるのではなく、前記重合部４を略水平方向に略１８０度回動することで前記操作部１を露出させることができる。
【００１８】
従って、前述のように操作部１を重合部４により隠蔽した状態のとき露出側となる上面側にディスプレイ部３を設けて機能性を高めても、重合部４を水平回動することで操作部１を露出できるため、操作部１を露出させてもディスプレイ部３は露出状態のままであり、操作部１を操作してディスプレイ部３に表示させる従来通りの使用も可能となる。
【００１９】
また、起伏回動でなく水平回動のため横押し操作により操作部１を露出できるため、開放動作が従来の起伏回動操作に比して容易に行え、扱い易い。
【００２０】
また、このヒンジ装置Ｈの回動軸部８は、前述のように第一の取付ベース５に設けた取付孔６に貫通係合した構成であり、この第一の取付ベース５は折り返したＵ状部材で形成され、この折り返し一側部に前記取付孔６を設けて、前記回動軸部８を所定角度で貫通係合するように設定したため、回動軸部８の軸方向を容易に設定でき、また、多少取り付け時に回動軸部の向きに誤差があってもこれを吸収して取り付けでき、しかもたとえ回動軸部に負荷がかかっても弾圧吸収されることとなるため、前記水平回動開閉式の電子機器を容易に実現できると共に、組み付けが容易となり、また常にスムーズに回動操作でき、耐久性にも秀れた画期的なヒンジ装置並びにこのヒンジ装置を用いた携帯電話，モバイル等の電子機器となる。
【００２１】
【実施例】
本発明の具体的な実施例について図面に基づいて説明する。
【００２２】
本実施例は、重合コンパクト化の図れる携帯電話に本発明を適用したもので、回路基板，電源等の電子部品をケースに内装した板状の第一部材２（本体部２）の上面側に数字キーやファンクションキーなどを配列したキーボード機能を果たす操作部１を設け、この本体部２に重合して操作部１を覆う略同形の板状の第二部材４（重合部４）を略水平回動自在にヒンジ装置Ｈにより軸着連結した構成としている。
【００２３】
この重合部４の上面側には予め設定した画面や前記操作部１の操作や着信等により所定の表示がなされる液晶パネルなどのディスプレイ部３を設けている。
【００２４】
この本体部２と重合部４との連結は、双方の端部同志の重合部分を、上下方向に配される回動軸部８を有するヒンジ装置Ｈにより連結し、この回動軸部８を回動支軸として略水平方向に回動自在に連結している。
【００２５】
また、本体部２も重合部４もヒンジ装置Ｈを組み付ける端部重合部分に対してやや立ち上がり傾斜状態（本体部分を水平に配すれば端部がやや立ち上がり傾斜状態）となるように形成し、重合した状態から重合部４を略１８０度水平回動して本体部２と重合部４とが一直線状に連設した状態とした際、重合部４のディスプレイ部３が本体部２に対してやや立ち起こされたように傾斜状態となり見易いように構成している。
【００２６】
次に本実施例のヒンジ装置Ｈについて説明する。
【００２７】
本実施例では、板材をＵ字状に折り返した第一の取付ベース５の下側片の両側部をビスなどで止着して本体部２の端部に取付固定し、この折り返し状の第一の取付ベース５の上側片中央に取付孔６を設け、一方中央に回動軸部８を回り止め固定した第二の取付ベース７を重合部４の端部に取付固定し、前記取付孔６に前記回動軸部８を挿通係合連結して、この上下方向に配される回動軸部８を回動支軸として本体部２に対して重合部４を略水平回動自在に連結する構成としている。
【００２８】
本実施例ではこのように構成することで取付孔６の形成向き（回動軸部８の軸方向）を回動がスムーズとなるように前記Ｕ字状に折り返した第一の取付ベース５の折り返し加減の設定により調整することができ、また、たとえ取付孔６と回動軸部８との向きに多少の誤差があってもこの折り返し状の第一の取付ベース５のたわみにより誤差が吸収されて軸着できる構成としている。
【００２９】
このように第一の取付ベース５を折り返し板材で形成し、この一側片に取付孔６を設けたから、たとえ回動軸部８に負荷が加わってもこの折り返し構造によりこの負荷を弾圧吸収でき、非常に回動がスムーズとなり耐久性にも秀れた構成となる。
【００３０】
また、本実施例での第一の取付ベース５の取付孔６と回動軸部８との連結は、座金12を介して取付孔６に挿通した回動軸部８に第一の取付ベース５に当接する板バネにより構成した弾性体９を介在して抜け止め連結部13で締め付け連結し、この弾性体９に形成した圧接部10が第一の取付ベース５に前記弾性体９により弾圧当接するように構成している。
【００３１】
即ち、リング状の板バネ９に突起を圧接部10として形成し、板バネ９を変形させるようにして抜け止め連結部13を回動軸部８に締め付け連結することで、この突起状の圧接部10が第一の取付ベース５に弾圧当接して、本体部２に対する重合部４の回動に抵抗が生じるように構成し、この回動抵抗を所定値に設定することで、スムーズに手で回動できるものの、手を放した位置で重合部４が係止保持されるいわゆるフリーストップ状態を実現できるように構成している。
【００３２】
また、本実施例では、回動軸部８の回動を所定位置で位置決め係止する位置決め係止機構11を設けて、前記重合部４が少なくとも前記本体部２の操作部１を覆うように重合する位置と、本体部２と直線状に連設状態となる位置で回動係止されるように構成している。
【００３３】
具体的には、本実施例ではこの位置決め係止機構11を前記突起状の圧接部10を利用して構成しているもので、前記取付孔６の孔縁にこの圧接部10が係合する凹縁部14（第一の取付ベース５に取付孔６とは別に係合孔を設けても良い）を設け、前記回動位置でこの圧接部10が第一の取付ベース５に圧接した状態からこの凹縁部14（あるいは係合孔）に落ち込んで位置決め係止されるように構成し、直線状に連設した状態やコンパクト化した重合状態でふらつき回動しないようにして使い易いようにしている。
【００３４】
また、本実施例では、回動軸部８の軸方向に空洞孔部８Ａを形成し、電気コードなどをこの空洞孔部８Ａに挿通配設して重合部４を回動する構成としても配線に支障がないように構成している。
【００３５】
また、本実施例では、第一の取付ベース５，第二の取付ベース７及び回動軸部８等を導電性の金属材で構成しているため、このヒンジ装置Ｈ自体を導電部として第一部材２（本体部２）側と第二部材４（重合部４）側とを電気的に接続するように構成しても良い。
【００３６】
また、本実施例では、使い勝手を良くすると共に配線に支障がないように過回動を防止するストッパー機構15を設けている。
【００３７】
このストッパー機構15は、前記第一の取付ベース５に切り出し（切り起こし）片15Ａを突設し、これに係止する切り出し（切り起こし）片15Ｂを前記抜け止め連結部13に形成して、この切り出し（切り起こし）片15Ａ，15Ｂ同志が過回動時に突き当たり係止することで所定方向の過回動を防止している。
【００３８】
即ち、図７に示すように、重合状態と連設状態とで位置決めされるが、夫々の回動方向において１８０度回動以上回動しようとするとこのストッパー機構15により係止ストップされ、必要以上に回動し得ないように構成している。
【００３９】
尚、本発明は、本実施例に限られるものではなく、各構成要件の具体的構成は適宜設計し得るものである。
【００４０】
【発明の効果】
本発明は上述のように構成したから、水平回動タイプの電子機器を容易に実現でき、しかもこの開閉回動が可能となるように容易に製作できる上、この開閉回動が常にスムーズに行え、耐久性にも秀れた画期的なヒンジ装置並びにヒンジ装置を用いた電子機器となる。
【００４１】
即ち、このヒンジ装置の回動軸部は、前述のように第一の取付ベースに設けた取付孔に貫通係合した構成であり、この取付ベースは折り返したＵ状部材で形成され、この折り返し一側部に前記取付孔を設けて、前記回動軸部を所定角度で貫通係合するように設定したため、回動軸部の軸方向を容易に設定でき、また、多少取り付け時に回動軸部の向きに誤差があってもこれを吸収して取り付けでき、しかもたとえ回動軸部に負荷がかかっても弾圧吸収されることとなるため、前記水平回動開閉式の電子機器を容易に実現できると共に、組み付けが容易となり、また常にスムーズに回動操作でき、耐久性にも秀れた画期的なヒンジ装置並びにこのヒンジ装置を用いた携帯電話，モバイル等の電子機器となる。

For example, a conventional foldable mobile phone is provided with an operation unit on which the numeric keys and function keys are arranged on the upper surface side of the lower main unit, and a liquid crystal panel on which a predetermined display is made by the key operation of the operation unit. The display part is provided on the lower surface side (polymerization side) of the superposition part on the upper side, this main part and superposition part are connected via a hinge device, and the main part and superposition part are folded in half and operated From the folded closed state in which the portion is concealed by the overlapping portion, the overlapping portion is turned upside down by the hinge device and reversed to be switched to an open state in which the operation portion and the display portion are exposed.
[0003]
Therefore, in a conventional electronic device that covers the operation part of the main body part with such a undulating and rotating superposition part, it can be folded and made compact, but the display part is also concealed in the superposition state where the operation part is concealed In many cases, use in a compact state is inevitably restricted.

[0012]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention (how to carry out the invention) considered to be suitable will be briefly described with reference to the drawings, showing its effects.
[0013]
For example, the first member 2 is provided with a first attachment base 5, the second member 4 is provided with a second attachment base 7, and the attachment holes 6 provided in the first attachment base 5 are connected to the second attachment base 7. By connecting the first member 2 and the second member 4 by penetrating and engaging the rotation shaft portion 8 provided, the hinge device causes the first member 2 and the second member 4 to overlap, The second member 4 can be rotated relatively parallel to the overlapping surface to expose the overlapping surface.
[0014]
Moreover, the first mounting base 5 is composed of a U-shaped member, and the orientation of the mounting hole 6 provided in one side portion of the U-shaped member can be adjusted by the degree of folding and the degree of folding elasticity. The mounting angle of the rotating shaft portion 8 that penetrates and engages with the mounting hole 6 can be appropriately set so that the second member 4 can be opened and closed along the overlapping surface from the state where the second member 4 is superimposed on the first member 2. Easy to do.
[0015]
Further, since the first mounting base 5 is formed of a U-shaped member and has a folded structure, a load is applied to the rotating shaft portion 8 engaged with the mounting hole 6 of the first mounting base 5. Even if added, the pressure can be absorbed, and a smooth rotation operation can be performed at all times, and the durability is greatly improved.
[0016]
Therefore, for example, if the first member 2 is the main body portion 2 provided with the operation portion 1 and the second member 4 is the overlapping portion 4 provided with the display portion 3, the end devices are overlapped and connected by the hinge device H. By doing so, the overlapping portion 4 can be connected to the main body portion 2 so as to be rotatable in a substantially horizontal direction. When the operation portion 1 is not operated, the main body portion 2 In this compacted polymerization state, the display unit 3 is disposed on the upper surface side of the polymerization unit 4, so that the display unit 3 can be operated even if the operation unit 1 cannot be operated. If the display unit 3 can be seen and the display unit 3 is configured to function, for example, a date or calendar set in advance by the operation unit 1 can be displayed, or a data communication display (for example, a mobile phone can be displayed). If or to perform the display, etc.), a display unit 3 enables various uses for visible, or spread intended use, improved functionality, very convenient and makes practical (commercial value) is increased.
[0017]
In addition, when operating the operation unit 1, the operation unit 1 is rotated by approximately 180 degrees in the substantially horizontal direction instead of rotating the overlapping unit 4 to expose the operation unit 1. Part 1 can be exposed.
[0018]
Therefore, even if the display unit 3 is provided on the upper surface side which is the exposed side when the operation unit 1 is concealed by the superimposing unit 4 as described above, the operation is performed by horizontally rotating the superimposing unit 4 even if the display unit 3 is enhanced. Since the unit 1 can be exposed, the display unit 3 remains exposed even when the operation unit 1 is exposed, and the conventional use in which the operation unit 1 is operated and displayed on the display unit 3 is also possible.
[0019]
In addition, since the operation unit 1 can be exposed by a horizontal pushing operation for horizontal rotation instead of up-and-down rotation, the opening operation can be easily performed and handled as compared with the conventional up-and-down rotation operation.
[0020]
Further, the rotation shaft portion 8 of the hinge device H is configured to penetrate through the mounting hole 6 provided in the first mounting base 5 as described above, and the first mounting base 5 is folded U. Since the mounting hole 6 is provided on one side of the folded portion and the rotation shaft portion 8 is set so as to penetrate through at a predetermined angle, the axial direction of the rotation shaft portion 8 can be easily set. It can be set, and even if there is an error in the orientation of the rotating shaft part during installation, it can be absorbed and attached, and even if a load is applied to the rotating shaft part, it will be absorbed and compressed. An electronic device that can be opened and closed horizontally is easily realized, easy to assemble, and can be rotated smoothly at all times. It is a revolutionary hinge device with excellent durability and a portable device using this hinge device. Electronic devices such as telephones and mobile phones.
