Description

本発明は、枢着装置並びに枢着装置を用いた携帯電話，モバイルなどの電子機器に関するものである。   The present invention relates to a pivot device and an electronic device such as a mobile phone and a mobile using the pivot device.

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など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。   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.

ところで、この折り畳み式の携帯電話は、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）させずらい欠点がある為、本体部と重合部との枢着部に配されるヒンジ装置に設けた解除操作部（押し込みボタン）を指で押すだけで、重合部の開放動作をワンタッチ式で簡易に行なえるタイプのヒンジ装置（以下、従来例）が提案されている。   By the way, in the case of operating the operation unit, this foldable mobile phone has to wake up a heavy overlapping portion provided with a display unit and rotate it in an inverted manner, making it difficult to open and close (especially an opening operation). Due to the drawbacks, the release operation of the overlapping part can be easily done with a single touch by simply pressing the release operation part (push-in button) provided on the hinge device located at the pivot part between the main part and the overlapping part. A type of hinge device (hereinafter, a conventional example) has been proposed.

ところが、この従来例は、一般に本体部を持つ手の親指で押し込みボタンを押すことになるが、実際に押し込みボタンを押し込む場合、他の指が重合部に干渉しない状態で本体部を持ちながら押し込みボタンを押さなければ成らない為、押し込みボタンが押しにくく（しっかり持っていない落としかねず）、ひいては押し込みボタンの押し込み操作がもたつくことで重合部の開放がかえって時間がかかってしまい、しかも、押し込みボタンはヒンジ装置の片側一方にのみ設けられる為、携帯電話を持つ利き手が逆の場合には不便である。   However, in this conventional example, the push button is generally pushed with the thumb of the hand holding the main body part. However, when the push button is actually pushed in, the other finger does not interfere with the overlapped part while holding the main body part. Since the button has to be pressed, it is difficult to press the push button (it can be dropped if you do not hold it firmly). Is provided only on one side of the hinge device, which is inconvenient if the dominant hand holding the mobile phone is reversed.

本出願人は、前述した折り畳み式の携帯電話の枢着構造に更なる実験・研究を重ね、より一層商品価値の高い画期的な枢着装置並びに枢着装置を用いた電子機器を開発した。   The Applicant has further experimented and researched on the pivoting structure of the foldable mobile phone described above, and developed an innovative pivoting device with higher commercial value and an electronic device using the pivoting device. .

また、本実施例では、第二部材２をスライド移動させた際、係合解除部８の端部が乗り上げることで該係合解除部８を移動させる乗り上げテーパー面を有する乗り上げ部９を第一部材１の枢着連結部に設けている。   In the present embodiment, when the second member 2 is slid, the end portion of the disengagement portion 8 rides on the end portion 9 having a rising taper surface that moves the disengagement portion 8. It is provided at the pivot connecting portion of the member 1.

具体的には、この乗り上げ部９は、図１４，１５に図示したようにガイド部27をスライド移動する取付部17の対向位置に凸状部９を設けて構成されており、第一部材１に対して第二部材２を枢着部方向へスライド移動させた際、この凸状部９を係合解除部８の基部８ａが乗り上げることで係合解除部８が軸状部材18の軸芯孔18ｂ内をスライド移動（前進移動）するように構成されている。   Specifically, as illustrated in FIGS. 14 and 15, the riding portion 9 is configured by providing a convex portion 9 at a position opposite to the mounting portion 17 that slides the guide portion 27. On the other hand, when the second member 2 is slid in the direction of the pivotally attached portion, the base portion 8a of the disengagement portion 8 rides on the convex portion 9 so that the disengagement portion 8 becomes the axis of the shaft-like member 18. It is configured to slide (forwardly move) in the hole 18b.

第二ヒンジ体Ｈ２について説明する。   The second hinge body H2 will be described.

重合部２（第二部材）には、前記取付孔部を解して回り止め形状とした第三連結体31の一部を構成する連結部としてのケーシング32を固定し、このケーシング32の一端側に露出状態で配される部材を第四連結体33の一部を構成する取付部34として取付孔部を介して本体部１（第一部材）に回り止め状態に固定している。このケーシング32は、図示したように断面八角形状としているが、これは重合部２に対する堅固な回り止め固定を達成するための構成であると共に、この回り止め構造を備えながら内部に効率よく部品を収納し得る形状としての八角形状を採用している。   The overlapping portion 2 (second member) is fixed with a casing 32 as a connecting portion that constitutes a part of the third connecting body 31 having a non-rotating shape by opening the mounting hole portion. A member arranged in an exposed state on the side is fixed to the main body 1 (first member) in a non-rotating state via an attachment hole as an attachment 34 constituting a part of the fourth connector 33. The casing 32 has an octagonal cross section as shown in the figure, and this is a structure for achieving a firm detent fixing with respect to the overlapped portion 2, and the components can be efficiently put inside while having this detent structure. An octagonal shape is adopted as a shape that can be stored.

また、前記取付部34の内孔34ａには先端部に回動付勢体22としてのトルクバネに連結される連結部材35が回り止め状態で設けられており、この回動付勢体22の他端部はケーシング32の他端部に回り止め状態で配設される連結部材36に連結されており、よって、回動付勢体22がケーシング32を回動させようとする付勢力が、ケーシング32を固定した状態とすることにより、今度は第四連結体33を回動させる付勢力として機能するように構成されている（これが開放回動付勢機構Ｓである。）。   Further, a connecting member 35 connected to a torque spring as a rotation urging body 22 is provided at the tip end of the inner hole 34a of the mounting portion 34 in a non-rotating state. The end portion is connected to a connecting member 36 disposed in a non-rotating state at the other end portion of the casing 32. Therefore, the urging force that the rotation urging body 22 tries to rotate the casing 32 is applied to the casing 32. By setting 32 in a fixed state, it is configured to function as an urging force for rotating the fourth connecting body 33 (this is the open rotation urging mechanism S).

この第二ヒンジ体Ｈ２に係る回動付勢体22により、本体部１に対して重合閉塞状態の重合部２は、本体部１に対して重合閉塞状態の重合部２を枢着部方向にスライド移動させた際、回動付勢体13に付勢されて前述した第一ヒンジ体Ｈ１に係る閉塞構造部としてのカム部18ａとカム係合部20ａとが係脱せずに係合状態のまま共同回動することで、本体部１に対して重合部２を最大開放角度位置まで自動開放させる開放回動付勢作用が生じるように構成されている。   Due to the rotation biasing body 22 relating to the second hinge body H2, the superposed portion 2 in a superposed and closed state with respect to the main body portion 1 causes the superposed portion 2 in a superposed and closed state with respect to the main body portion 1 in the pivoting portion direction. When the slide is moved, the cam portion 18a and the cam engaging portion 20a as the closing structure portion related to the first hinge body H1 are urged by the rotation urging body 13 and are engaged without being disengaged. By being jointly rotated as it is, an opening rotation biasing action for automatically opening the overlapping portion 2 to the maximum opening angle position with respect to the main body portion 1 is generated.

また、第二ヒンジ体Ｈ２は、図１５に図示したように第四連結体33を構成する取付部34が、第二枢着部25Ｂにして第一部材１に設けられるガイド部27を付勢体28に抗してスライド移動するように構成されている。   Further, in the second hinge body H2, as shown in FIG. 15, the mounting portion 34 constituting the fourth connecting body 33 urges the guide portion 27 provided in the first member 1 as the second pivoting portion 25B. The body 28 is configured to slide against the body 28.

従って、前述した第一ヒンジ体Ｈ１と共に第一部材１と第二部材との枢着連結部25に組み付けた際、第一部材１に対して重合状態の第二部材２を付勢体28に抗して枢着部方向へスライド移動し得るように構成されている。   Therefore, when the first hinge body H1 and the first member 1 and the second member are assembled to the pivot joint 25, the second member 2 in a superposed state with respect to the first member 1 is used as the biasing body 28. It is configured to be able to slide and move in the direction of the pivoting portion.

その余は第一実施例と同様である。   The rest is the same as in the first embodiment.

尚、本発明は、実施例１，２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。   The present invention is not limited to the first and second embodiments, and the specific configuration of each component can be designed as appropriate.
