The present invention relates to a parallel biaxial hinge and a small electronic device including the parallel biaxial hinge.

２軸ヒンジには、第１ヒンジシャフトと第２ヒンジシャフトを互いに交わる方向へ配置した交叉２軸ヒンジと、互いに平行方向へ配置した平行２軸ヒンジとがあるが、本願発明は後者の平行２軸ヒンジに属する。   The biaxial hinge includes a crossed biaxial hinge arranged in a direction in which the first hinge shaft and the second hinge shaft cross each other and a parallel biaxial hinge arranged in a direction parallel to each other. It belongs to the shaft hinge.

この平行２軸ヒンジは、１軸のヒンジに較べて、第１の筐体と第２の筐体を手に持った本を開くように左右均等に開くことができるという利点がある。そこで、第１ヒンジシャフトと第２ヒンジシャフトを同期回転させるために、同期回転伝達手段として歯車を用いたものが下記特許文献１によって公知である。   This parallel biaxial hinge has an advantage that it can be opened equally to the left and right so as to open a book holding the first casing and the second casing in comparison with a uniaxial hinge. Therefore, Japanese Patent Application Laid-Open No. 2004-133867 discloses a gear using a gear as a synchronous rotation transmission means for synchronously rotating the first hinge shaft and the second hinge shaft.

次に、本件発明に係る平行２軸ヒンジ２の作用について説明する。まず、平行２軸ヒンジのブリッジ部材５を連結部材２ａへ取り付け、第１ブラケット１２を第１の筐体３の後端部側に取り付け、第２ブラケット１３を第２の筐体４の後端部側へ取り付ける。第１の筐体３と第２の筐体４を閉じた状態においては、同期回転伝達手段Ａの第１リンクカム部材７と第２リンクカム部材８は、互いの第１及び第２リンクピン７ｂ、８ｂをスライド部材６の第１及び第２係合凹部６ｃ、６ｄと係合させていることにより、スライド部材６を図７に示したように左方向へ押し込んでその始端部側へ位置させている。この状態において、図９（ａ）に示したように、第１固定カム部１４と第２固定カム部１５の凹部１４ｂ、１５ｂ内へ第１及び第２カム部材１９、２０の凸部１９ａ、２０ａが完全に落ち込む手前に位置しているので、第２ヒンジシャフト１１が第２ブラケット１３を介して第２の筐体４を閉成方向へ回転付勢されることによって、第１の筐体３に対する第２の筐体４の閉成状態が維持されている。   Next, the operation of the parallel biaxial hinge 2 according to the present invention will be described. First, the parallel biaxial hinge bridge member 5 is attached to the connecting member 2 a, the first bracket 12 is attached to the rear end side of the first housing 3, and the second bracket 13 is attached to the rear end of the second housing 4. Attach to the side. In a state where the first housing 3 and the second housing 4 are closed, the first link cam member 7 and the second link cam member 8 of the synchronous rotation transmitting means A are mutually connected to the first and second link pins. By engaging 7b and 8b with the first and second engaging recesses 6c and 6d of the slide member 6, the slide member 6 is pushed to the left as shown in FIG. I am letting. In this state, as shown in FIG. 9A, the convex portions 19a of the first and second cam members 19, 20 are inserted into the concave portions 14b, 15b of the first fixed cam portion 14 and the second fixed cam portion 15, respectively. Since the second hinge shaft 11 is rotationally biased in the closing direction by the second hinge shaft 11 via the second bracket 13 since the position 20a is completely dropped, the first case The closed state of the second housing 4 with respect to 3 is maintained.

尚、第１ブラケット１２と第２ブラケット１３は、前者を第２の筐体４へ、後者を第１の筐体３へ取り付けても良い。また、第１ブラケット１２と第２ブラケット１３は、これらを省略して、第１ヒンジシャフト１０と第２ヒンジシャフト１１を、それぞれ直接第１の筐体３或は第２の筐体４へ取り付けるようにしても良い。   Note that the first bracket 12 and the second bracket 13 may be attached to the second housing 4 for the former and to the first housing 3 for the latter. Further, the first bracket 12 and the second bracket 13 are omitted, and the first hinge shaft 10 and the second hinge shaft 11 are directly attached to the first casing 3 or the second casing 4, respectively. You may do it.

次に、ノーパソコン１を使用すべく、第１の筐体３と第２の筐体４を手に持って本を開くようにして左右へ開くと、第１の筐体３と第２の筐体４のどちらの側に力を加えても、同期回転伝達手段Ａによって、第１ヒンジシャフト１０と第２ヒンジシャフト１１は共に同一回転角度それぞれ反対側へ回転することになる。即ち、第１ヒンジシャフト１０と第２ヒンジシャフト１１のどちらの側に回転トルクを加えても、共に回転する同期回転伝達手段Ａの第１リンクカム部材７或は第２リンクカム部材８によって、スライド部材６が、図８に示したように、上方へスライドして他方の第１リンクカム部材７或は第２リンクカム部材８が第１ヒンジシャフト１０或は第２ヒンジシャフト１１を介して第１ブラケット１２或は第２ブラケット１３を回転させるので、第１の筐体３と第２の筐体４は第１及び第２ヒンジシャフト１０、１１と共に、同じ開角度で開かれて、図８に示したように、左右均等に９０°に開かれた状態となる。この時には、図９（ｃ）に示したように、第１及び第２カム部材１９、２０の凸部１９ａ、２０ａは、第１及び第２固定カム部１４、１５のもう一方の凹部１４ｂ、１５ｂへ完全に落ち込む寸前で停止し、第１の筐体３と第２の筐体４を全開状態でロックする形となる。   Next, in order to use the no personal computer 1, holding the first casing 3 and the second casing 4 in the hand and opening the book to the left and right, the first casing 3 and the second casing 2 are opened. Regardless of which side of the housing 4 is applied, the first and second hinge shafts 10 and 11 are rotated to the opposite side by the same rotation angle by the synchronous rotation transmitting means A. That is, the first link cam member 7 or the second link cam member 8 of the synchronous rotation transmission means A that rotates together regardless of which side of the first hinge shaft 10 and the second hinge shaft 11 is rotated, As shown in FIG. 8, the slide member 6 slides upward, and the other first link cam member 7 or second link cam member 8 passes through the first hinge shaft 10 or the second hinge shaft 11. Since the first bracket 12 or the second bracket 13 is rotated, the first housing 3 and the second housing 4 are opened together with the first and second hinge shafts 10 and 11 at the same opening angle. As shown in FIG. 8, the left and right sides are evenly opened at 90 °. At this time, as shown in FIG. 9C, the convex portions 19a and 20a of the first and second cam members 19 and 20 are connected to the other concave portions 14b of the first and second fixed cam portions 14 and 15, respectively. The first housing 3 and the second housing 4 are locked in a fully opened state, stopping just before they completely fall into 15b.

それ以外の第１の筐体３と第２の筐体４の中間開閉角度においては、図９（ｂ）に示したように、第１固定カム部１４及び第２固定カム部１５の凸部１４ａ、１５ａと第１及び第２カム部材１９、２０の凸部１９ａ、２０ａ同士が、互いに圧接状態で推移するので、フリクショントルクが発生する。   At other intermediate opening / closing angles of the first housing 3 and the second housing 4, as shown in FIG. 9B, the convex portions of the first fixed cam portion 14 and the second fixed cam portion 15. 14a and 15a and the convex portions 19a and 20a of the first and second cam members 19 and 20 are in pressure contact with each other, so that friction torque is generated.

このようにして、第１の筐体３と第２の筐体４は、閉成状態から本を開くように左右均等に開かれ、同期回転伝達手段Ａとカムを用いた第１及び第２フリクション機構９ａ、９ｂによりガタが生じることが少ないので、スムーズなしっくりとした操作フィーリングを操作者へ与えることができるものである。   In this way, the first housing 3 and the second housing 4 are equally opened left and right so as to open the book from the closed state, and the first and second using the synchronous rotation transmission means A and the cam. Since the friction mechanisms 9a and 9b are less likely to cause backlash, a smooth and comfortable operation feeling can be given to the operator.

その他の実施例として、同期回転伝達手段Ａのスライド部材６に第１及び第２リンクピンを取り付け第１及び第２リンクカム部材７、８の側に前記第１及び第２リンクピンと係合する第１及び第２係合孔或は第１及び第２係合溝を設けるように構成しても良く、さらに、スライド部材６はガイドシャフト１７を省略して、ブリッジ部材５によって抱えるように構成しても良い。さらに、カム付の第１及び第２フリクション機構９ａ、９ｂは、第１及び第２固定カム部１４、１５と第１及び第２カム部材１９、２０を省略して、公知の第１及び第２フリクション機構とすることも可能である。この場合は、第１及び第２カム部材１９、２０をブリッジ部材５の軸受プレート部５ａと圧接する第１及び第２フリクションワッシャーとする公知構成のものとするものである。   As another embodiment, the first and second link pins are attached to the slide member 6 of the synchronous rotation transmitting means A and engaged with the first and second link pins on the first and second link cam members 7 and 8 side. The first and second engagement holes or the first and second engagement grooves may be provided, and the slide member 6 is configured to be held by the bridge member 5 by omitting the guide shaft 17. You may do it. Further, the first and second friction mechanisms 9a and 9b with cams omit the first and second fixed cam portions 14 and 15 and the first and second cam members 19 and 20, and can perform the first and second known mechanisms. A two-friction mechanism is also possible. In this case, the first and second cam members 19, 20 are of a known configuration as first and second friction washers that are in pressure contact with the bearing plate portion 5 a of the bridge member 5.

本発明は以上のように構成したので、小型電子機器の第１の筐体と第２の筐体を互いに重なり合った閉成状態から、ガタのないしっくりとした操作フィーリングで本を開くように開閉する際の平行２軸ヒンジ並びにこの平行２軸ヒンジを用いた小型電子機器として好適に用いられるものである。   Since the present invention is configured as described above, the book can be opened with a loose operation feeling from the closed state in which the first housing and the second housing of the small electronic device overlap each other. The present invention is suitably used as a parallel biaxial hinge when opening and closing and a small electronic device using the parallel biaxial hinge.
