本発明は、例えば携帯電話，モバイル，ノート型パソコン，デジタルカメラ等の電子機器の枢着部に設けるヒンジ装置並びにこのヒンジ装置を用いた電子機器に係るものである。 The present invention is, for example, mobile phones, mobile phones, it relates to an electronic device using a laptop computer, the hinge apparatus and the hinge device provided in the pivot portion of an electronic device such as a digital camera.
二つの部材の端部同志をヒンジ装置で連結して一方に対して他方を回動自在に構成する場合、単に一方の部材に面一状態にヒンジ装置を設け、このヒンジ装置を介して他方の部材を連結したのでは、一方の部材に対して他方の部材を回動しても双方の部材を重合状態とすることはできない。 When configuring rotatably the other for one connects the end comrades two members at the hinge device, the hinge device flush state is provided solely on one of the members, the other through the hinge device than the concatenation of the members can not be both members and the polymerization conditions also rotates the other member relative to the one member.
即ち、例えば所定厚の板状の部材同志を互いに重合した状態から一方の部材に対して他方の部材を１８０度あるいは１８０度近く起伏開放回動するように構成する場合、この双方の部材の端部間にヒンジ装置を組み込むが、このヒンジ装置は軸受部若しくは軸部またはこれらを取り付けるための取付部を一方の部材の端部の上方に突設し、これに他方の部材に設ける軸部若しくは軸受部またはこれらを組み付けたヒンジ装置を取り付けて、互いに重合する状態まで回動できるように構成する。 That is, for example, when constituting the other member relative to the one member from the state polymerized together a plate-like member comrades predetermined thickness to 180 degrees or 180 degrees near the relief opening rotation, the end of the both members part inter incorporating a hinge device, this hinge device protruding mounting portion for mounting the bearing unit or the shaft portion or those over the end of one of the members, or the shank this provided the other member Install the hinge device assembled bearing unit or these are configured to be rotated to a state polymerization together. いずれにしてもヒンジ装置の軸部は、いずれかの部材に対して対向側に突出した位置に架設しなければ重合状態に閉塞できない。 Shank also hinge device In any case, it can not be closed in the polymerised state unless bridged position protruding to the opposite side with respect to any of the members.
従って、図１２（ａ）に示すように重合状態にできるようにするためにこのようにしてヒンジ装置を一方の部材に対して上方に突出状態に設けざるをえないために、例えば一方の部材に対して他方の部材を例えば１５０〜１８０度開放回動して双方の部材が直線状に連設した開放状態においては、その中間部にどうしてもヒンジ装置による突出部が形成され双方の開放面は面一とはならず段差部が生じ、開放した場合に平坦な開放連設面とはならない。 Therefore, in order to not help provided projecting state upwardly for one of the members of the hinge device in this manner in order to be able to polymerization conditions as shown in FIG. 12 (a), for example, one member the other member for example, 150 to 180 degrees open pivot with respect in the open state in which both members are provided continuously in a straight line, the open surfaces of both the protrusions formed by just the hinge device in the middle portion the stepped portion is caused not become flush, not a flat open communication 設面 when opened.
もう少し具体的な例で説明すれば、例えば携帯電話やパソコンなど操作部を表面に設けた本体部に対してディスプレイ部を設けた開閉部を互いに重合した状態から、操作部，ディスプレイ部とが共に露出する開放状態まで起伏回動自在となるようにこの本体部と開閉部との端部同志をヒンジ装置を介して連結するが、互いに重合状態となる位置まで閉塞回動できるようにするためには、前述のように本体部と開閉部との端部間に面一状態にヒンジ装置を納めることはできず、例えば本体部の端部上方に突出状態にヒンジ装置を組み込む取付部を左右に設け、この取付部間に開閉部の端部に設けたヒンジ装置を組み付けて重合状態から略１８０度開放回動自在に構成しなければならなかった。 To describe in a little more specific example, for example, the opening and closing section provided with a display unit an operation unit such as a mobile phone or personal computer to the main body portion provided on the surface from each other polymerized state, the operation unit, and a display unit together While the end comrades of the main body portion to the open state so as to be freely undulating pivoting exposing the opening and closing unit linked via a hinge device, in order to be able to closed pivoted to a position where the polymerization with each other is not able to pay the hinge device flush state between the ends of the body portion and the closing portion as described above, the right and left mounting portion incorporating the hinge device protruding state example above the end of the body portion provided, it had to be constructed freely approximately 180 ° opening pivoting the hinge device provided on the end portion of the closing part from the polymerization state assembled between the mounting portion.
そのため、互いに重合できるものの、本体部の端部の上方に突出するヒンジ装置を介して開閉部を連結しているため、１８０度回動しても双方の開放面が面一な平坦面となることはなく、開閉部の基部には本体部の端部から突出状態に配されるヒンジ装置が存在する。 Therefore, although capable of polymerizing with each other, since the coupling-off portion via a hinge device that protrudes above the end of the body portion, the open surfaces of both is flush flat surface be 180 degrees rotation it is not, the base of the closing part there is a hinge device which is disposed in the projecting state from the end of the body portion.
特願２００４−２４３９６２号 Japanese Patent Application No. 2004-243962
そこで、出願人は、図１２（ｂ）に示すように重合状態とすることができ、且つヒンジ装置を１８０度起伏回動して互いの開放面が面一（平坦面）となるように組み込み構成するために、このヒンジ装置を二軸構成とすることを見い出した。 Therefore, applicant has built so can be polymerized state as shown in FIG. 12 (b), the open face of each other is flush (flat surface) with and 180 ° undulating pivoting the hinge device to construct was found that the hinge device having two axes configuration.
即ち、例えば一方の部材の端部と他方の部材の端部間に平行二軸のヒンジ装置を組み込み連結することで、この二軸によって一方の部材に対して他方の部材が起伏回動し、これによって互いに重合する状態から例えば他方の部材を１８０度開放回動すると、双方の部材の開放面が面一となった平坦な開放面となるように構成でき、しかも例えばこの二軸のヒンジ装置を双方の部材の板厚内の寸法に抑えれば、中間部に突出部が全く存在しない平坦な開放面となるヒンジ装置を用いた開閉自在な電子機器が実現できることとなる。 That is, for example, by embedded connecting hinge parallel biaxial between the ends of the end and the other member of one member, the other member undulating rotated with respect to the one member by the biaxial, If thereby 180 degrees open rotated from the state such as the other member to be polymerized to each other, can be configured to be a flat open surface in which the open surfaces of both members becomes flush, moreover e.g. the biaxial hinge device if Osaere to dimensions in the thickness of both members, so that the openable electronic apparatus using the hinge device comprising a flat open surface of the projecting portion in the intermediate portion does not exist at all it can be realized.
また、このように二軸構成とすることで一方の部材に対して他方の部材を３６０度起伏回動でき、一方の部材の片面に他方の部材を重合した状態から一方の部材の反対面に他方の部材を重合する状態まで回動できる構成を容易に実現できる構成となる。 Further, the opposite surface of the thus the other member relative to the one member by the biaxial structure can 360 degrees undulating pivoting, one member from a state obtained by polymerizing other member on one side of one of the members a configuration that can be rotated to a state polymerizing the other member becomes easily realized can be configured.
しかしながら、図１３に示すように各二軸は何ら規制なく回動することから一方の部材に対して他方の部材がふらつくことになるという問題が生じる。 However, a problem that the biaxially As shown in FIG. 13 the other members will fluctuate that for one of the members from that any restriction without rotation occurs.
たとえこのふらつきがないように各軸に対する回動に対してトルクを生じさせて手をはなしたところで停止するフリーストップを実現させたとしても、二軸のため各軸が各々勝手に回動するため所望の位置へ回動させることはスムーズには行えない。 Even if it allowed to realize free stop which stops when release the hand cause torque to rotate with respect to each axis so as not this wobble, respectively freely rotating each axis for biaxial It is for rotation to the desired position can not be performed smoothly.
そこで、本発明は、二軸構成として重合状態とすることがこれまで通り可能となるヒンジ装置としつつも、開放回動した際にこのヒンジ装置が中央部で突出する位置になく、双方の部材の開放面が面一となるように構成でき、ヒンジ装置もこの開放面と略面一若しくは突出しないように納めることが可能となり、更に前述のような二軸によるふらつきなどの問題も解決され、各部材の二軸のヒンジ装置に対する回動量を完全な同期回動ではなくともほぼ同期規制させてふらつきなくスムーズに回動させることが可能となる画期的な構造の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。 Accordingly, the present invention, the double to a shaft configured to polymerization conditions while still a hinge device that enables as before, this hinge device upon opening rotation is not in the position projecting in the central portion, both members open faces can be configured to be flush, the hinge apparatus also becomes possible to fit to not this open face substantially flush with or protruding further solved problems such as fluctuation due to biaxial as described above, use a hinge device as well as the hinge device of innovative structure it is possible to rotate smoothly without wobbling by restricting substantially synchronous if not the rotation amount with respect to the hinge device for a secondary axis of each member in perfect synchronization rotation is an object of the present invention to provide an electronic device had.
また、既に前記技術課題を解決すべく同期手段として歯車による歯合連結を用いた構成とした図１４に示す特許出願（特願２００４−２４３９６２号）を提出済みであるが、このような歯車（ギア）式とすると、ギアの歯当たりの感触「ゴリゴリ感」が出てしまうだけでなく、コスト高となり、また軸間ピッチが離れていると中間ギアが必要となり、この点でもコスト高となり組み付けも厄介となって量産性に劣る。 Although already submitted a patent application (Japanese Patent Application No. 2004-243962) as shown in FIG. 14 where the structure using the meshing connection by gear as synchronizing means to solve the above technical problem, such gears ( When gear) type, not only the feel of the tooth of the gear "Gorigori feeling" will come out, it is costly and the intermediate gear when the inter-shaft pitch away is necessary, also assembling becomes costly in this respect inferior to mass production also become a nuisance. また、軸間ピッチ一定でも、ギア径を小さくすると、中間ギアがやはり必要となり、コスト高となったり、省スペース化が図れない（セットを薄くできない）等の問題を有する。 Further, even in the inter-axial pitch constant has the smaller gear diameter, becomes the intermediate gear is still required, or a high cost, a not space-saving (can not be thinner set) or the like problems.
本発明は、このギア式の欠点をも解決し、軸間ピッチ，占有スペースに自由度があり、コスト高にもなりにくく省スペース化も図れる等一層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。 The present invention, this also solves the disadvantages of geared axial pitch, there is a degree of freedom in the space occupied, innovative hinge device and the hinge was more Xiu like attained also space saving hardly becomes costly and its object is to provide an electronic apparatus using the device.

好適と考える本発明の実施形態（発明をどのように実施するか）を、図面に基づいて本発明の作用を示して簡単に説明する。 The embodiments of the present invention considered to be preferred (how to implement the invention) will be briefly described show the effect of the present invention with reference to the accompanying drawings.
ヒンジ基体３を第一部材１と第二部材２との間に配設し、第一回動軸部４を介して第一部材１の端部とヒンジ基体３とを枢着し、第二回動軸部５を介してヒンジ基体３と第二部材２の端部とを枢着して、中間部のヒンジ基体３に対して第一部材１を第一回動軸部４を介して起伏回動自在に設けると共にヒンジ基体３に対して第二部材２を第二回動軸部５を介して起伏回動自在に設ける。 A hinge base 3 disposed between the first member 1 and second member 2, the end portion and the hinge base 3 of the first member 1 pivotally mounted via the first rotating shaft 4, the second and pivoted to an end portion of the hinge base 3 and the second member 2 via the rotating shaft portion 5, the first member 1 with respect to the hinge base 3 of the intermediate portion via the first rotating shaft 4 undulations pivotably to the hinge base 3 a second member 2 via the second rotating shaft portion 5 undulations rotatably provided provided with.
従って、第一部材１に対して第二部材２は、二軸（第一回動軸部４，第二回動軸部５）を介して起伏回動自在となる。 Thus, the second member 2 against the first member 1 is a freely undulating pivoting through a twin-screw (first rotating shaft 4, the second pivot shaft part 5).
従って、例えばこの平行二軸間の距離、即ちヒンジ基体３の長さ寸法の設定によって、図１２（ｂ）に示すようにたとえ第一部材１と第二部材２との端部間にこの二軸を備えたヒンジ基体３を配設して、第一部材１と第二部材２とを開放した際に開放面に突出部や段差部がなく平坦となるように設計しても、二軸の回動によってヒンジ基体３も回動して平行二軸の位置も第一部材１に対して回動するため、第一部材１と第二部材２とが互いに重合した状態に回動できることとなる。 Thus, for example, the distance between the two parallel axes, namely a hinge by setting the length of the base body 3, and FIG. 12 (b) in the first member 1 even as shown this two between the ends of the second member 2 by arranging the hinge base 3 provided with a shaft, be designed to protrusion or stepped portion on the open surface upon opening the first member 1 and second member 2 becomes flat without biaxial for rotating with respect to the hinge base 3 is also the first member 1 even when the position of the two parallel axes rotated by the rotation, can be rotated in a state where the first member 1 and second member 2 are polymerized with each other and Become.
例えば板状の第一部材１と板状の第二部材２の端部間に双方の部材１，２の板厚間に納まるようにして二軸を備えたヒンジ基体３を配設して各軸（第一回動軸部４，第二回動軸部５）と各部材（第一部材１，第二部材２）とを枢着することで、第一部材１と第二部材２とが互いに重合した状態から開放回動させることができ、常にこの第一部材１と第二部材２の間には従来のように第一部材１や第二部材２のいずれかの端部上面から上方に軸部や軸受部やヒンジ装置を組み付ける取付部を突出させる構成とすることなく重合閉塞可能となり、中間部にほとんど突出部が生じないように構成することが可能となる。 For example, each be disposed a hinge base 3 so as to fit between the plate thickness of both members 1, 2 between the ends of the plate-like first member 1 and the plate-shaped second member 2 with a two-axis axis (first rotating shaft 4, the second pivot shaft part 5) and the members (first member 1, second member 2) by pivotally and, the first member 1 and second member 2 from There can be opened rotated from the state polymerized together, always the first member 1 and the second member is between 2 either end upper surface of the first member 1 and second member 2 as in the prior art upper polymerizable closable and will not be configured to protrude the attachment portion to assemble the shaft portion and the bearing portion and the hinge device, it is possible to constitute so little protrusion on the intermediate portion does not occur.
具体的には例えば、図１，図７，図９に示すように第一部材１に対して第二部材２を１５０度〜１８０度（例えば１７０度）開放回動自在とすれば、中間部に全く突出部を生じない平坦な連設開放面が形成される構成でありながら、重合状態に閉塞可能なヒンジ装置を実現できることとなる。 More specifically, for example, 1, 7, the second member 2 to 150 degrees to 180 degrees relative to the first member 1 as shown in FIG. 9 (e.g. 170 degrees) if freely open rotation, the intermediate portion quite yet configurations flat continuously arranged open surface which does not cause protrusion is formed, so that the closable hinge device can be realized in the polymerized state in.
しかも、本発明では、第一部材１に対するヒンジ基体３の回動に伴って回動する（第一部材１若しくはヒンジ基体３に対して相対回動する）第一回動部６を第一回動軸部４に設け、ヒンジ基体３に対する第二部材２の回動に伴って回動する（ヒンジ基体３若しくは第二部材２に対して相対回動する）第二回動部７を第二回動軸部５に設け、この第一回動部６と第二回動部７とを連動リンク部17で連結し、一方の回動によって他方が伝達連動回動（同期回動）する構成としたから、図１３に示すように夫々の軸（第一回動軸部４，第二回動軸部５）が規制なく勝手に回動するのではなく、常に略同期して回動する（ギア式のように完全に同期しない場合もあるが、少なくとも同じ起伏回動方向に連動回動する）。 Moreover, in the present invention, (it rotates relative to the first member 1 or the hinge base 3) the rotation for with rotation of the hinge base 3 with respect to the first member 1 a first pivot portion 6 first round provided shaft portion 4, with the rotation of the second member 2 with respect to the hinge base 3 (which relative rotation with respect to the hinge base 3 or second member 2) to rotate the second pivot portion 7 second provided to the rotation shaft portion 5, the this first pivot portion 6 and the second pivot portion 7 is connected by interlocking link portion 17, constituting the other by one rotation is transmitted interlocked rotation (synchronous rotation) since was, 13 in the respective axis as shown in (first pivot shaft part 4, second pivot shaft part 5) rather than to freely rotate without restriction, constantly rotating substantially in synchronism (it may not be completely synchronized to the gear-type, but interlocked pivots least as undulating pivoting direction).
即ち、各軸は勝手に回動せず、第一回動軸部４の回動は常に第一回動部６，第二回動部７とが連動リンク部17によって連結されていることから第二回動軸部５を回動することになり、図７，図８，図９に示すようにヒンジ基体３に対して第一部材１が相対回動するに伴って必ずヒンジ基体３に対して第二部材２が相対回動することとなるため、第一部材１に対して二軸を備えたヒンジ基体３を介して第二部材２を回動させる際、ふらつくことなく所望の位置へスムーズに回動できることとなる。 That is, each axis will not freely rotate, since the rotation of the first rotating shaft 4 is always the first pivot portion 6, and a second pivot portion 7 are connected by a coupling link portion 17 will be rotating the second rotating shaft portion 5, 7, 8, always hinge base 3 with the first member 1 are relatively rotated with respect to the hinge base 3 as shown in FIG. 9 since the second member 2 so that the relative rotation for, when the second member 2 is rotated via the hinge base 3 with a two-axis with respect to the first member 1, the desired position without wobbling the ability to smoothly rotate in the.

具体的には、前記ヒンジ基体３は前記第一部材１及び前記第二部材２の厚みと略同等とし、前記第一回動軸部４，第二回動軸部５，第一回動部６，第二回動部７の径も第一部材１及び第二部材２の厚みと略同等とし、このヒンジ基体３の第一部材１側及び前記第二部材２側に夫々前記回動軸部４，５を並設して第一部材１に対して第二部材２例えば１７０度開放した開放状態においては第一部材１と第二部材２との枢着部分に各部材１，２の厚みに対して少なくとも１.５倍以上の突出部が生じず略平坦な開放面が第一部材１と第二部材とにより連設形成されるように構成すると共に、この第一部材１と第二部材２の開放面が互いに合わさる重合状態まで閉じ回動し得るように構成している。 Specifically, the hinge base 3 is substantially equal to the thickness of the first member 1 and the second member 2, the first rotating shaft 4, the second pivot shaft part 5, first pivot portion 6, the diameter of the second pivot portion 7 is also the first member 1 and the thickness of the second member 2 substantially equal, respectively the pivot shaft to the first member 1 side and the second member 2 side of the hinge base 3 the parts 4,5 relative to the first member 1 and arranged in the open state in which the open second member 2, for example 170 degrees of the respective members 1 to pivotally portion of the first member 1 and second member 2 together configured to be continuously provided formed by substantially flat open surface not at least 1.5 times the protrusions cause the first member 1 and the second member relative to the thickness, this first member 1 second open face of the second member 2 is configured to be able to rotate close to mate polymerization with each other.
また、更に説明すると、連動リンク部17は、前記第一回動部６と前記第二回動部７との間に架設状態に配設する棒状若しくは板状であって直線状やＳ字状などの所定形状の前記バー基体17Ａの両端部に夫々前記取付部17Ｂを設け、前記第一回動部６若しくは前記第二回動部７の回動によって前記第二回動部７若しくは前記第一回動部６を押動又は引動して一方の回動力を他方に押動伝達又は引動伝達するように構成している。 Moreover, further will be described, interlock link portion 17, the first time a rod-like or plate-like arranging the bridging state between the moving part 6 and the second pivot portion 7 straight or S-shaped respectively the mounting portion 17B is provided at both ends of the bar base 17A of a predetermined shape, such as, the second pivot portion 7 or the by the rotation of the first pivot portion 6 or the second pivot portion 7 a constitutes one of the rotational force one rotation unit 6 by pressing or 引動 to push transfer or 引動 transmitted to the other.
即ち、この取付部17Ｂを前記第一回動部６及び前記第二回動部７に取り付ける取付位置は、前記第一部材１に対して前記ヒンジ基体３若しくは前記ヒンジ基体３に対して前記第二部材２が前記第一部材１と前記第二部材２とが重合した閉塞位置から起伏回動して開放位置となる開放方向に回動した際、前記第一回動部６若しくは前記第二回動部７がこの開放回動に伴って相対回動することによって、この回動力が前記バー基体17Ａによって押動伝達若しくは引動伝達されて、前記第二回動部７若しくは前記第一回動部６が、前記ヒンジ基体３に対して前記第二部材２が若しくは前記第一部材１に対して前記ヒンジ基体３が同じ前記開放方向に同期して連動回動する偏心位置に設定している。 That is, the mounting position for mounting the mounting portion 17B to the first pivot portion 6 and the second pivot portion 7, the first relative to the hinge base 3 or the hinge base 3 with respect to the first member 1 when two members 2 is rotated in the opening direction of the open position by undulating pivoted from the closed position to the first member 1 and said second member 2 are polymerized, the first pivot section 6 or the second by rotating portion 7 is relatively rotated in accordance with this opening rotation, the rotational force is pushed transmitted or 引動 transmitted by the bar base 17A, the second pivot portion 7 or the first pivot part 6 is set at an eccentric position of the hinge base 3 wherein the second member 2 or to the first member 1 with respect to the hinge base 3 is interlocked rotates in synchronization with the same said opening direction .
従って、例えば図９に示すように１７０度開放状態から第一部材１に対して第二部材２を回動する際、ヒンジ基体３に対して第二部材２を第二回動軸部５を軸に例えば図８に示すように３１度回動すると、ヒンジ基体３も第一部材１に対して第一回動軸部４を軸に完全に同期しないものの同期方向に４５度回動して略同期回動し、最終的にこの同期回動によって一方が９０度回動すると他方も９０度同期回動して第一部材１に対して第二部材２が１７０度回動し、図７に示すように重合状態となるように構成している。 Thus, for example, when rotating the second member 2 against the first member 1 from 170 degrees open as shown in FIG. 9, the second member 2 second rotating shaft portion 5 relative to the hinge base 3 with 31 degrees rotation as shown in the axis in FIG. 8 example, the hinge body 3 be 45 degrees rotation in synchronization direction but not fully synchronized to the axis of the first rotating shaft portion 4 with respect to the first member 1 substantially synchronous rotation, eventually one of 90 degrees the second member 2 against movement to the first member 1 and the other also 90 degrees synchronous rotation is 170 degrees rotation by the synchronous rotation, FIG. 7 It is configured to be polymerized state as shown in.
更に説明すると、所定形状に形成され前記第一回動部６と前記第二回動部７との間に架設配設される前記連動リンク部17のバー基体17Ａは、前記第一回動部６と前記第二回動部７との軸間ピッチ方向に対して傾斜する方向に架設配設し、このバー基体17Ａの両端部に設けた取付部17Ｂの取付位置は、前記第一回動部６と前記第二回動部７とが前記連動回動する回動角が略同一角度となり略同期回動する前記第一回動部６及び前記第二回動部７の偏心位置に設定している。 With further described, bar base 17A of the interlock link portion 17 which is bridged disposed between formed into a predetermined shape and the first pivot portion 6 and the second pivot portion 7, the first pivot portion 6 and bridged arranged in a direction inclined with respect to the axis-to-axis pitch direction and the second pivot portion 7, the mounting position of the mounting portion 17B which is provided at both ends of the bar base 17A, the first pivot set at an eccentric position of the first pivot portion 6 and the second pivot portion 7 for rotating angle section 6 and said second pivot portion 7 is the interlocking rotation is moving substantially synchronized times becomes substantially the same angle are doing.
具体的には、前記連動リンク部17の前記バー基体17Ａの前記軸間ピッチ方向に対して傾斜配設する角度Ｄを、第一回動部６、第二回動部７の各軸の動作角度範囲において、両軸間ピッチを２Ｈ、軸中心から前記連動リンク部17の前記取付部17Ｂを取り付けるリンク接続点距離（偏心距離）をＲとしたとき、図１０に示す式で求めた角度としている。 Specifically, the inclined arrangement angle D with respect to the axial pitch direction of the bar base 17A of the interlock link portion 17, first pivot portions 6, the operation of each axis of the second pivot portion 7 in the angular range, the pitch between the axes 2H, the link connection point distance for mounting the mounting portion 17B of the from the axial center interlock link portion 17 (eccentricity) when the R, as the angle determined by the formula shown in FIG. 10 there.
従って、連動リンク部17の架設配設位置、即ち取付偏心位置の工夫設定によって完全に同期しないまでも連動回動角が大きくズレず略同一となり、できるだけ略同期した連動回動となるように設定している。 Thus, erection arrangement position of the interlock link portion 17, i.e. devised set of mounting the eccentric position is also linked rotation angle becomes substantially equal not a greatly deviated, if not completely synchronized with, so that possible substantially synchronized with interlocking rotation It is set.
しかも前記角度Ｄの最適化によって、完全同期に近似した略同期した回動（連動回動）となり、この連動回動の最適化が図られ、例えば力の伝達が開放方向と閉塞方向で同じ条件となり、前記連動回動角の差（両軸の動作角度の差）を最小化できる（完全に同一角度となって完全に同期することにはならないもののこれを最小化して完全同期に近づけられる）こととなる。 Moreover optimization of the angle D, completely synchronized with the approximated substantially synchronized pivoting (interlocking rotation), and this optimization interlocking rotation is achieved, for example, the transmission of force is the same condition in the opening direction and the closing direction next, (brought close to full synchronization to minimize this but not to completely synchronize a completely same angle) to minimize possible differences in the interlocking rotation angle (the difference between the operation angles of both axes) and thus.
この最適化のための数式を図10に示したが、この式を適用することにより力のバランスが最適化され、また角度ズレについても最大で４５度と４２.７度と最適化される。 While the formula for the optimization shown in FIG. 10, by applying the formula is optimized balance of forces, and is 45 degrees and 42.7 degrees and optimized up also the angular deviation.
この各角度値は、数式の各パラメータ設定によって変わってくるものである。 Each angle values are those varies by each parameter set formulas.
また、図１１に示す別例のように、前記連動リンク部17のバー基体17Ａの端部を夫々前記第一回動部６及び第二回動部７の周回方向に湾曲してこの第一回動部６及び前記第二回動部７の軸と干渉しない形状に設定しても良い。 Further, as another example shown in FIG. 11, the interlock link portion 17 of the bar base 17A of the end portion of each said first pivot section 6 and the first curved in the circumferential direction of the second pivot portion 7 it may be set to a shape that does not interfere with the shaft of the rotation unit 6 and the second pivot portion 7. 具体的にはバー基体17Ａの両端部を軸回りに湾曲してＳ字形状に設定しても良い。 Specifically it may be set to S-shape by bending the opposite ends of the bar base 17A around the axis in the.
従って、このような形状とすることで両軸に干渉することがなく、またこの連動リンク部17の生産性の向上が図れる等一層秀れたヒンジ装置となる。 Therefore, such a shape as not to interfere with both axes by also hinge device like was more Xiu thereby improving the productivity of the interlock link portion 17.
