このようなヒンジ機構を備えることにより、下記特許文献１の折畳み式携帯電話機は、蓋体ケース８２が本体ケース８４に対してスムーズに折畳み開閉ができるようになる。
特開２００１−２５１３９６号公報（図２、図５、段落〔００１６〕〜〔００２１〕） By providing such a hinge mechanism, the foldable mobile phone disclosed in Patent Document 1 described below allows the lid case 82 to be smoothly folded and opened with respect to the main body case 84.
JP 2001-251396 A (FIG. 2, FIG. 5, paragraphs [0016] to [0021])

上記特許文献１に記載された折畳み携帯電話機において、本体ケースと蓋体ケースの間には、両ケース内の制御回路基板同士を電気的に接続して各種信号の伝達を行うために、フレキシブルプリント配線基板（ＦＰＣ：Flexible Printed Circuit。以下、単にＦＰＣと述べる。）等の連結配線が接続されている。   In the folding cellular phone described in Patent Document 1, a flexible print is provided between the main body case and the lid case in order to electrically connect the control circuit boards in both cases to transmit various signals. A connecting wiring such as a wiring board (FPC: Flexible Printed Circuit; hereinafter simply referred to as FPC) is connected.

しかしながら、上記特許文献１に開示された折畳み式携帯電話機は左右に設けられたヒンジ機構８５、８５’が同一軸線上に配置しているので、このようなヒンジ機構内にＦＰＣを配線すると、両ケースの開閉時にＦＰＣが撓んだり、あるいは引っ張られたりするためにＦＰＣに捩れが生じたり、比較的大きな引張力が加わったりして破損する恐れがある。特に、このような負荷はＦＰＣの特にヒンジ機構上に位置する部分に集中している。   However, since the folding mobile phone disclosed in Patent Document 1 has hinge mechanisms 85 and 85 ′ provided on the left and right sides on the same axis, both FPCs are wired in such a hinge mechanism. Since the FPC is bent or pulled when the case is opened and closed, the FPC may be twisted or may be damaged due to a relatively large tensile force. In particular, such a load is concentrated on a portion of the FPC located particularly on the hinge mechanism.

本発明者らは、上記問題点に鑑み、連結配線のヒンジ機構が設けられた位置に生じるストレスを分散することで、上記問題点を解決できることを見出した。詳しくは、両機器ケースを連結するヒンジ機構の回転軸を２つ設けることで回転軸が１つの場合に比べて回転軸ごとに回転する角度を半分にすることができることを見出し本発明に至ったものである。   In view of the above problems, the present inventors have found that the above problems can be solved by dispersing the stress generated at the position where the hinge mechanism of the connection wiring is provided. Specifically, it has been found that the rotation angle of each rotation axis can be halved by providing two rotation axes of the hinge mechanism for connecting the two device cases as compared with the case of one rotation axis. Is.

すなわち、本発明の目的は、両機器ケース間を電気的に接続する連結配線に生じるストレスを分散して破損し難くした折畳み式電子機器を提供することである。   That is, an object of the present invention is to provide a foldable electronic device in which stress generated in a connection wiring that electrically connects both device cases is dispersed and is not easily damaged.

また、請求項９に記載の発明は、請求項１に記載の折畳み式電子機器において、 前記連結配線は、所定径を有する同軸ケーブルであることを特徴とする。   The invention according to claim 9 is the foldable electronic device according to claim 1, wherein the connection wiring is a coaxial cable having a predetermined diameter.

また、請求項１０に記載の発明は、請求項９に記載の折畳み式電子機器において、前記同軸ケーブルは、両端部に前記制御回路基板に設けられた接続部に接続される端子片が形成された柔軟性を有するケーブル状体からなり、前記第１、第２回転軸の軸心に沿って形成された連通穴内を通過するように配線されていることを特徴とする。   According to a tenth aspect of the present invention, in the foldable electronic device according to the ninth aspect, the coaxial cable has terminal pieces connected to connection portions provided on the control circuit board at both ends. It is characterized by being made of a cable-like body having flexibility and wired so as to pass through the communication hole formed along the axis of the first and second rotating shafts.

本発明は上記構成を備えることにより、以下に示すような優れた効果を奏する。すなわち、請求項１の発明によれば、ヒンジ機構として２軸式のものを使用し、このヒンジ機構に沿って連結配線を配線して両機器ケースの接続を行っているので、機器ケースの開閉動作によって連結配線に生じるストレスを各軸に分散し、このストレスが連結配線の一部に集中しないようにしたため、連結配線が撓むあるいは引っ張られることによって破損することを防止することができる。詳しくは、連結配線の各箇所にストレスが集中することなく、また、回転軸が２軸存在するために、この２軸周辺の開閉時に生じる撓み等を許容するためのスペースが多くとれるため、撓みが発生しても、この撓みによって連結配線にストレスが掛かり難く、以って破損が生じにくくなる。また、連結配線に第１〜第４屈曲部を設けたので、機器ケースの開閉動作によって生じるストレスをこの４つの屈曲部に分散させることができるので、より連結配線の破損を防止することができるようになる。更に、ヒンジ部分の狭いスペースを有効活用できる。   By providing the above configuration, the present invention has the following excellent effects. That is, according to the first aspect of the present invention, a biaxial type hinge mechanism is used, and the connecting case is connected by wiring the connecting case along the hinge mechanism. Since stress generated in the connection wiring by the operation is distributed to each axis so that the stress is not concentrated on a part of the connection wiring, it is possible to prevent the connection wiring from being damaged by being bent or pulled. Specifically, since stress does not concentrate on each part of the connection wiring, and there are two rotation axes, there is a lot of space for allowing bending or the like that occurs when opening and closing around these two axes. Even if this occurs, it is difficult for stress to be applied to the connecting wiring due to this bending, and thus damage is less likely to occur. In addition, since the first to fourth bent portions are provided in the connection wiring, the stress caused by the opening / closing operation of the device case can be distributed to the four bent portions, so that damage to the connection wiring can be further prevented. It becomes like this. Furthermore, the narrow space of the hinge portion can be effectively used.

また、請求項２の発明によれば、連結配線を近接する両機器ケースの隅部同士を連通するように配線されるので、連結配線を比較的短くすることができるようになる。   According to the invention of claim 2, since the connecting wiring is wired so as to communicate the corners of both device cases adjacent to each other, the connecting wiring can be made relatively short.

また、請求項３、４の発明によれば、連結配線としてフィルムからなるＦＰＣを用いた場合であっても、機器ケースの複数回にわたる開閉動作にも破損を良好に防止することができる。   Further, according to the third and fourth aspects of the invention, even when an FPC made of a film is used as the connection wiring, breakage can be satisfactorily prevented even when the device case is opened and closed several times.

また、請求項５の発明によれば、ＦＰＣの長手方向に直交する２辺を回転軸に沿って配線することによりこの２辺に回動時のストレスが生じることがなくなる。   According to the fifth aspect of the present invention, the two sides perpendicular to the longitudinal direction of the FPC are wired along the rotation axis, so that no stress is generated during the rotation of these two sides.

また、請求項６の発明によれば、各屈曲部を回転軸を中心に所定角度（例えば１８０°）回転させることにより、開閉動作を行った際には、この回転部分の径が拡大・縮小するようになり、ＦＰＣに直接応力がかかることがない。   According to the invention of claim 6, when the opening / closing operation is performed by rotating each bent portion by a predetermined angle (for example, 180 °) about the rotation axis, the diameter of the rotating portion is enlarged or reduced. Thus, the FPC is not directly stressed.

また、請求項７の発明によれば、屈曲部に角部を設けることなく円弧状にすることで、角部に応力が集中することがないため、破損が生じ難くなる。   According to the seventh aspect of the present invention, since the arc portion is not provided at the bent portion, the stress does not concentrate on the corner portion, so that the breakage hardly occurs.

また、請求項８の発明によれば、請求項１に記載の発明の効果に示したように、回転軸が２つ存在するために、ＦＰＣの配線スペースを多くとることができるため、両機器ケースの制御基板間を多くの配線を用いて接続したい場合に、ＦＰＣを重ね合わせて配線しても、ＦＰＣにストレスが掛かりにくいので、配線数に応じてＦＰＣの枚数を容易に変更することができる。   Further, according to the invention of claim 8, as shown in the effect of the invention of claim 1, since there are two rotating shafts, a large FPC wiring space can be obtained. When it is desired to connect the control boards of the case using many wires, even if the FPCs are overlapped and wired, the FPC is not stressed easily, so the number of FPCs can be easily changed according to the number of wires. it can.

また、請求項９に記載の発明によれば、連結配線にＦＰＣではなく、同軸ケーブルを用いても、破損を生じることなく両機器ケースの制御基板間を接続することができる。   According to the ninth aspect of the present invention, even if a coaxial cable is used instead of the FPC for the connection wiring, the control boards of both device cases can be connected without causing damage.

また、請求項１０に記載の発明によれば、同軸ケーブルを柔軟性を備えたケーブルから構成し、２つの回転軸に沿って屈曲させて連通させることで、両制御基板を接続することができる。この場合、同軸ケーブルは２つの回転軸に沿って配線されるので、上記請求項１に記載の発明の効果に示すように、屈曲部分ごとに生じるストレスが分散されるので、破損等を良好に防止することができる。   According to the invention described in claim 10, the coaxial cable is formed of a flexible cable, and the two control boards can be connected by bending and communicating along two rotation axes. . In this case, since the coaxial cable is wired along the two rotation axes, as shown in the effect of the invention described in claim 1 above, the stress generated for each bent portion is dispersed, so that the breakage and the like are improved. Can be prevented.

このＦＰＣ６は、図４（ａ）に示すように、先端部に各制御回路基板３、１４に接続される端子部を有する比較的長尺な端子片６ａ、６ｂと、これらの端子片６ａ、６ｂ間にあって略コ字状に屈曲されてヒンジ機構２０に組付けられる連結片６ｃとで構成されている。各端子片６ａ、６ｂは連結片６ｃに比べて若干幅広に形成され各制御回路基板３、１４の接触端子（図示省略）に接続される端子部となっている。   As shown in FIG. 4 (a), the FPC 6 includes relatively long terminal pieces 6a and 6b each having a terminal portion connected to each control circuit board 3 and 14 at the tip portion, and these terminal pieces 6a, 6b and a connecting piece 6c which is bent in a substantially U shape and is assembled to the hinge mechanism 20. Each terminal piece 6a, 6b is formed to be slightly wider than the connecting piece 6c and serves as a terminal portion connected to a contact terminal (not shown) of each control circuit board 3, 14.

連結片６ｃは、各端子片６ａ、６ｂの他端からそれぞれ所定長さ延びた位置に設けられる長手方向に対してほぼ直角に屈曲された第１円環部６1、６1と、この第１円環部６1、６1から直角に所定長さ延びた第１接続片６2、６2と、この第１接続片６2、６2の端部に設けられ、第１接続片６2、６2の端部同士が接続されるようにほぼ直角に屈曲された第２円環部６3、６3と、この第２円環部６3、６3同士を接続する第２接続片６4と、を有している。なお、第１円環部６1、６1及び第２円環部６3、６3は、図に示すように。長手方向中心部を境にして対称になるようにその屈曲方向が設定されている。また、ヒンジ機構２０に沿って配線された連結片６ｃはヒンジカバーＣにより覆われている。 The connecting piece 6c includes first annular portions 6 1 , 6 1 bent substantially at right angles to the longitudinal direction provided at positions extending a predetermined length from the other ends of the terminal pieces 6a, 6b, 1 annular parts 6 1, first connection piece 6 which extends a predetermined length from 6 1 perpendicularly 2, 6 2, provided at the end of the first connection piece 6 2, 6 2, first connection piece 6 2, a 6 second annular parts 6 3 2 ends are substantially right angle bend so as to be connected, 6 3, second connection that connects the second annular parts 6 3, 6 3 together It has a strip 6 4. The first annular parts 6 1 , 6 1 and the second annular parts 6 3 , 6 3 are as shown in the figure. The bending direction is set so as to be symmetric with respect to the central portion in the longitudinal direction. Further, the connecting piece 6 c wired along the hinge mechanism 20 is covered with a hinge cover C.

ＦＰＣ６の携帯電話機１内の配線は、図２、図４（ｂ）に示すように、連結片６ｃの第１円環部６1、６1をヒンジ機構２０の第１フレーム２１の第２アーム片２４、及び第２フレーム４１の第４アーム片４４の側面に位置する一方の隅部１５ｂ、１６ｂ内に配設するとともにこの一方の隅部１５ｂ、１６ｂで第１円環部６1、６1をヒンジ機構２０の２つの回動軸を軸として所定角度、例えば１８０°回転させ、第１接続片６2、６2の一部を第２アーム片２４及び第４アーム片４４の腕部に形成されたＵ字状溝２５ｃ、４５ｃに挿入する。また、第２円環部６3、６3を第１、第２フレーム２１、４１の長手方向の中間部付近に配設し、ヒンジ機構２０の２つの回動軸を軸として更に例えば１８０°回転させ、ここで第２接続片６4をヒンジ機構２０の連結部材３０の結合片３１上に固定する。 As shown in FIG. 2 and FIG. 4B, the wiring inside the mobile phone 1 of the FPC 6 is connected to the first annular portions 6 1 , 6 1 of the connecting piece 6 c by the second arm of the first frame 21 of the hinge mechanism 20. piece 24, and the corner portion 15b, a first annular parts 6 at 16b 1 corners 15b, of the one as well as disposed within 16b one of which flank the fourth arm piece 44 of the second frame 41, 6 1 is rotated by a predetermined angle, for example, 180 ° about two rotation axes of the hinge mechanism 20, and a part of the first connection pieces 6 2 , 6 2 is part of the arm portions of the second arm piece 24 and the fourth arm piece 44. Are inserted into the U-shaped grooves 25c and 45c. Further, the second annular portions 6 3 , 6 3 are disposed in the vicinity of the middle portion in the longitudinal direction of the first and second frames 21, 41, and further, for example, 180 ° about the two rotating shafts of the hinge mechanism 20. rotate wherein securing the second connection piece 6 4 on the joining piece 31 of the connecting member 30 of the hinge mechanism 20.

このＦＰＣ６は、連結片６ｃに第１円環部６1、６1と、第１接続片６2、６2と、第２円環部６3、６3とを有し、第２円環部６3、６3を第２接続片６4で接続したことにより、携帯電話機１を開閉させてもＦＰＣ６に捩れが生じる可能性のある部分が無くなる。より具体的には、送話ケース２のＦＰＣ６が配線された一方の隅部１５ｂと、受話ケース１０のＦＰＣ６が配線された一方の隅部１６ｂとが一直線上に隣接しているため、捩れが生じることを防止できる。また、携帯電話機１は、ヒンジ機構２０の回転軸が２本となっているため、この回転軸に沿って配線されたＦＰＣ６は、開状態を例えば１６０°開いた状態とすると、回転軸が１軸の場合はヒンジ機構部分に配線されたＦＰＣに１６０°回転させた分のストレスがかかるが、回転軸が２軸になっていると、１つの回転軸に生じる回転角は１軸の場合の半分の８０°であるため、かつ１つの回転軸に生じる回転角が小さくなり、ＦＰＣ６にかかるストレスもこの２軸部分に分散されるため、ＦＰＣ６の耐久寿命を飛躍的に増加させることができる。また、この２つの回転軸上においても屈曲部である円環部６1、６1、６3、６3を２つずつ設けているので、回転軸上に生じるストレスを更に分散することができる。 This FPC 6 has first annular portions 6 1 , 6 1 , first connecting pieces 6 2 , 6 2, and second annular portions 6 3 , 6 3 on a connecting piece 6c, and a second annular ring. parts by 6 3, 6 3 are connected by the second connection piece 6 4, the cellular phone 1 is opened and closed a twisted FPC6 even that might have partially disappears. More specifically, since one corner 15b to which the FPC 6 of the transmission case 2 is wired and one corner 16b to which the FPC 6 of the reception case 10 are wired are adjacent to each other in a straight line, the twist is not caused. It can be prevented from occurring. Further, since the mobile phone 1 has two rotation axes of the hinge mechanism 20, the FPC 6 wired along the rotation axis has a rotation axis of 1 when the open state is, for example, 160 °. In the case of a shaft, stress is applied to the FPC wired to the hinge mechanism part by a rotation of 160 °. However, if the rotation shaft is two, the rotation angle generated on one rotation shaft is the same as that in the case of one shaft. Since it is half of 80 ° and the rotation angle generated on one rotating shaft is reduced and the stress applied to the FPC 6 is also distributed to the two shaft portions, the durable life of the FPC 6 can be dramatically increased. In addition, since the two annular portions 6 1 , 6 1 , 6 3 , and 6 3 are provided on each of the two rotation shafts, the stress generated on the rotation shaft can be further dispersed. .

また、２本の回転軸でヒンジ機構を構成することにより、このヒンジ機構２０内には１軸のヒンジ機構に比べてスペースが多く生じ、このスペースが携帯電話機を開閉した際に生じるＦＰＣ６のたわみを許容するスペースとして使用できるので、ＦＰＣ６にかかるストレスをより減少させることができる。   Further, since the hinge mechanism is constituted by two rotating shafts, a space is generated in the hinge mechanism 20 as compared with the single-shaft hinge mechanism, and the flexure of the FPC 6 generated when the mobile phone is opened and closed. Therefore, the stress applied to the FPC 6 can be further reduced.

したがって、ＦＰＣ６に無理な応力が加わることがなく、捩れによる配線の切断等の事故を回避でき、第２接続部６4をヒンジ機構２０の連結部材３０の結合片３１に両面接着テープ或いは他の固着手段に固定すれば、第２接続部６4が移動し、障害物に引っ掛かり損傷することもなくなる。 Therefore, it is to join an excessive stress to the FPC 6, can avoid accidents such as cutting of wire by twisting, double-sided adhesive tape or other binding piece 31 of the connecting member 30 of the second connecting portion 6 4 of the hinge mechanism 20 be fixed to the fixing means, the second connecting portion 6 4 is moved, also eliminates damaging caught on obstructions.

なお、上記実施例では、送話ケース２及び受話ケース１０の制御基板をＦＰＣ６により接続するものとしたが、本発明はこれに限定されることなく、例えば同軸ケーブル等を用いてもよい。この場合、同軸ケーブルをリンク機構の回転軸の軸心部分を挿通させるようクランク状に配設すれば、ＦＰＣ６を使用した場合と同様に、同軸ケーブルにかかるストレスを削減することができる。   In the above embodiment, the control boards of the transmission case 2 and the reception case 10 are connected by the FPC 6, but the present invention is not limited to this, and for example, a coaxial cable or the like may be used. In this case, if the coaxial cable is arranged in a crank shape so that the axial center portion of the rotation shaft of the link mechanism is inserted, the stress applied to the coaxial cable can be reduced as in the case where the FPC 6 is used.

更に、この実施例ではＦＰＣ６を各回転軸に沿って配設する際、第１円環部６1、６1及び第２円環部６3、６3において回転軸に沿って所定角回転させるようにしたが、このように回転させずにクランク状のＦＰＣ６を設けてもよく、この場合にも、ヒンジ機構２０内に比較的広いスペースが存在するため、ＦＰＣ６のたわみ及び捩れを良好に抑えることができる。 Further, in this embodiment, when the FPC 6 is disposed along each rotational axis, the first annular portions 6 1 and 6 1 and the second annular portions 6 3 and 6 3 are rotated by a predetermined angle along the rotational axis. However, the crank-shaped FPC 6 may be provided without rotating in this manner, and in this case as well, since a relatively wide space exists in the hinge mechanism 20, the deflection and the twist of the FPC 6 are suppressed satisfactorily. be able to.

ヒンジ機構２０は、図５、図６に示すように、送受話ケース２、１０内に収容された支持枠４、１３に装着される一対の第１、第２フレーム２１、４１と、これらの第１、第２フレーム２１、４１を連結する第３フレームとしての連結部材３０と、この連結部材３０で連結された第１、第２フレーム２１、４１をそれぞれ折畳み位置から所定角度に回動したとき、その駆動を規制・保持する第１、第２駆動機構５０、５０と、第１、第２フレーム２１、４１を連係し、両フレームの駆動を連動させるリンク機構６０と、送話ケース２及び受話ケース１０の開及び閉時にこの開状態及び閉状態を維持するストッパー機構７０、７０と、で構成されている。   As shown in FIGS. 5 and 6, the hinge mechanism 20 includes a pair of first and second frames 21 and 41 attached to the support frames 4 and 13 housed in the transmission / reception cases 2 and 10, and these The connecting member 30 as a third frame for connecting the first and second frames 21 and 41 and the first and second frames 21 and 41 connected by the connecting member 30 are respectively rotated from the folding position to a predetermined angle. The first and second drive mechanisms 50 and 50 for regulating and holding the drive, the link mechanism 60 for linking the first and second frames 21 and 41, and the drive of both frames, and the transmission case 2 And stopper mechanisms 70 and 70 that maintain the open and closed states when the receiving case 10 is opened and closed.

第１、第２フレーム２１、４１、連結部材３０、第１、第２駆動機構５０、５０、リンク機構６０及びストッパー機構７０、７０を構成する部品は、殆どが金属製の剛体からなり、これらは金属製の板材を打ち抜き、折曲するプレス加工することによって形成される。金属材としては、高強度、高剛性及び高じん性のステンレス製のばね材（例えば、ＳＵＳ３０４ＣＳＰ−１／２Ｈ）が好ましい。また、第１、第２フレーム２１、４１の板厚は、例えば１．５ｍｍ、連結部材３０の板厚は、例えば１．２ｍｍである。このように各部品を金属材で形成することにより、従来の樹脂材で作製したものに比べてヒンジ機構の機械的強度を高くできるので部品を小型にできる。また、ヒンジ機構２０全体を金属製の剛体で形成することにより、支持枠４、１３が電気的に接続されるので、支持枠４、１３のいずれかが備えるアンテナの受信面積を大きくでき、アンテナの性能を向上させることができる。   The components constituting the first and second frames 21 and 41, the connecting member 30, the first and second drive mechanisms 50 and 50, the link mechanism 60, and the stopper mechanisms 70 and 70 are mostly made of metal rigid bodies.

As the metal material, a stainless steel spring material (for example, SUS304CSP-1 / 2H) having high strength, high rigidity, and high toughness is preferable. The plate thickness of the first and second frames 21 and 41 is, for example, 1.5 mm, and the plate thickness of the connecting member 30 is, for example, 1.2 mm. By forming each component with a metal material in this way, the mechanical strength of the hinge mechanism can be increased as compared with a conventional resin material, so that the component can be made smaller. Moreover, since the support frames 4 and 13 are electrically connected by forming the hinge mechanism 20 as a whole by a metal rigid body, the reception area of the antenna provided in either of the support frames 4 and 13 can be increased, and the antenna Performance can be improved.

第２連結片３３は、第２、第４結合部３５、３７を備え、それぞれストッパー部材７１、７１に設けられた第２取付け軸７３、７３が装着される取付け穴３５ａ、３７ａと、第２、第４結合部３５、３７の外縁部に設けられストッパー部材７１、７１が装着された状態でこれらのストッパー部材７１、７１の回動を所定角度に制限する係止突起３５ｂ、３７ｂと、がそれぞれ形成されている。したがって、各ストッパー部材７１、７１が所定角度回動されると、係止爪７１ａ、７１ｂが係止突起３５ｂ、３７ｂに衝突して回動が制限される。この回動制限は、第２、第４アーム片２４、４４の回動制限、すなわち、第１、第２フレーム２１、４１の回動制限となる。   The second connecting piece 33 includes second and fourth coupling portions 35 and 37, and mounting holes 35a and 37a in which second mounting shafts 73 and 73 provided on the stopper members 71 and 71 are mounted, respectively, Locking projections 35b and 37b that are provided on the outer edge portions of the fourth coupling portions 35 and 37 and restrict the rotation of the stopper members 71 and 71 to a predetermined angle in a state where the stopper members 71 and 71 are mounted. Each is formed. Therefore, when the stopper members 71 and 71 are rotated by a predetermined angle, the locking claws 71a and 71b collide with the locking projections 35b and 37b, and the rotation is restricted. This rotation limitation is the rotation limitation of the second and fourth arm pieces 24, 44, that is, the rotation limitation of the first and second frames 21, 41.

すなわち、各ストッパー部材７１、７１は、第２、第４アーム片２４、４４の取付け穴２４ｂ、４４ｂ及び突起２５ａ、２５ｂ、４５ａ、４５ｂにより回り止めされて固定されるので、第２、第４アーム片２４、４４が回動されると、この回動にしたがって各ストッパー部材７１、７１も回動し、所定角度回動すると、各ストッパー部材７１、７１の係止爪７１ａ、７１ｂが係止突起３５ｂ、３７ｂに衝突して回動が制限される。   That is, each stopper member 71, 71 is fixed by being prevented from rotating by the mounting holes 24b, 44b and the projections 25a, 25b, 45a, 45b of the second and fourth arm pieces 24, 44. When the arm pieces 24 and 44 are rotated, the stopper members 71 and 71 are also rotated according to the rotation. When the arm pieces 24 and 44 are rotated by a predetermined angle, the locking claws 71a and 71b of the stopper members 71 and 71 are locked. The rotation is restricted by colliding with the projections 35b and 37b.

各係止突起３５ｂ、３７ｂの高さは、後述するストッパー部材７１の肉厚より低く、それぞれ第２、第４結合部３５、３７の底辺部に形成されている。なお、第２、第４アーム片２４、４４に設けられた突起２５ａ、２５ｂ、４５ａ、４５ｂと第２、第４結合部３５、３７に設けられた係止突起３５ｂ、３７ｂとが接触しないように、両突起の高さを加算した長さは、ストッパー部材７１の肉厚より若干短くしてある。   The heights of the locking projections 35b and 37b are lower than the thickness of a stopper member 71 described later, and are formed at the bottoms of the second and fourth coupling portions 35 and 37, respectively. The protrusions 25a, 25b, 45a, 45b provided on the second and fourth arm pieces 24, 44 are not in contact with the locking protrusions 35b, 37b provided on the second and fourth coupling portions 35, 37. In addition, the length obtained by adding the heights of both protrusions is slightly shorter than the thickness of the stopper member 71.

ここで、以下には先ずストッパー機構７０について説明する。   Here, first, the stopper mechanism 70 will be described first.

ストッパー機構７０は、第１及び第２フレーム２１、４１に固定された一対のストッパー部材７１、７１と、第１及び第２フレーム２１、４１の回動に伴ってこのストッパー部材７１、７１に当接し、その回動を規制する係止突起３５ｂ、３７ｂとから構成されている。   The stopper mechanism 70 is a pair of stopper members 71 and 71 fixed to the first and second frames 21 and 41, and the stopper members 71 and 71 come into contact with the rotation of the first and second frames 21 and 41. It is comprised from the latching protrusions 35b and 37b which contact | connect and regulate the rotation.

ストッパー部材７１、７１は、いずれも同一の構造を有しているので、以下には第２アーム片２４に取付けられるストッパー部材７１について説明する。しかしながら、第２アーム片２４に取付けられるストッパー部材７１と第４アーム片４４に取付けられるストッパー部材７１とは連結部材３０を境に左右対称に配置されている。   Since both the stopper members 71 and 71 have the same structure, the stopper member 71 attached to the 2nd arm piece 24 is demonstrated below. However, the stopper member 71 attached to the second arm piece 24 and the stopper member 71 attached to the fourth arm piece 44 are disposed symmetrically with respect to the connecting member 30 as a boundary.

このストッパー部材７１は、ほぼ円形で所定肉厚の板体の外周縁の２箇所から法線方向に係止爪７１ａ、７１ｂが突出した形状を有し、平面視においてほぼ三日月状であって、その表裏面のほぼ中心に第１、第２取付け軸７２、７３を有し、この三日月状の先端部が係止爪７１ａ、７１ｂとなっている。各係止爪７１ａ、７１ｂは、第１取付け軸７２を中心にして所定角度θ（図示省略）離れている。第１取付け軸７２は取付け穴２４ｂに嵌合されるように非円形状に形成し、第２アーム片２４の取付け穴２４ｂへ嵌着されることで回り止めを行う。また、第２取付け軸７３は、第２結合部３５の取付け穴３５ａに挿通される太さで、且つ第２結合部３５の肉厚より若干長くなっている。そして、取付け穴３５ａに挿入された後第２取付け軸７３の先端部をかしめることで取付け穴３５ａに回動自在に固定される。なお、各係止爪７１ａ、７１ｂのなす角θは、例えば携帯電話機１に実装された際の所望の最大回転角を等分し、かつその角度に係止突起３５ｂ、３７ｂの円周方向の延設角度を加えた角度とする。   The stopper member 71 has a shape in which locking claws 71a and 71b protrude in the normal direction from two locations on the outer peripheral edge of the plate body having a substantially circular shape and a predetermined thickness, and is substantially crescent-shaped in plan view, First and second mounting shafts 72 and 73 are provided at substantially the center of the front and back surfaces, and the crescent-shaped tip portions serve as locking claws 71a and 71b. Each locking claw 71a, 71b is separated from the first mounting shaft 72 by a predetermined angle θ (not shown). The first mounting shaft 72 is formed in a non-circular shape so as to be fitted into the mounting hole 24b, and is prevented from rotating by being fitted into the mounting hole 24b of the second arm piece 24. The second mounting shaft 73 is thick enough to be inserted into the mounting hole 35 a of the second coupling part 35 and slightly longer than the thickness of the second coupling part 35. Then, after being inserted into the attachment hole 35a, the tip end portion of the second attachment shaft 73 is caulked to be rotatably fixed to the attachment hole 35a. Note that the angle θ formed by each of the locking claws 71a and 71b is, for example, equally divided into a desired maximum rotation angle when mounted on the mobile phone 1, and the angle of the locking protrusions 35b and 37b in the circumferential direction is equal to that angle. The angle plus the extension angle.

ストッパー部材７１は、金属材、特に機械的強度の強いステンレス鋼で作製されている。このような金属材でストッパー部材７１を作製すると、第１、第２フレーム２１、４１の一方に過度な力が加わっても各係止爪７１ａ、７１ｂが係止突起３５ｂ、３７ｂに係止されるため、破損等が生じにくくなる。   The stopper member 71 is made of a metal material, particularly stainless steel having a high mechanical strength. When the stopper member 71 is made of such a metal material, even if an excessive force is applied to one of the first and second frames 21 and 41, the locking claws 71a and 71b are locked to the locking projections 35b and 37b. Therefore, damage or the like is less likely to occur.

次に、駆動機構５０について説明する。   Next, the drive mechanism 50 will be described.

第１フレーム２１の第１アーム片２２の結合部２２ａ及び第２フレーム４１の第３アーム片４２の結合部４２ａには、それぞれ駆動機構５０、５０が設けられている。各駆動機構５０、５０は、第１、第２フレーム２１、４１を所定位置に規制・保持するカム機構と、このカム機構を駆動するバネ体とを備え、第１、第２フレーム２１、４１の回動にしたがってこれらのフレームを間歇移動させるものである。第１アーム片２２及び第３アーム片４２に設けられた駆動機構とは、同様の構成からなるため、同一の符号を付し、以下には第１アーム片２２に取付けられた駆動機構５０についてのみ説明を行う。   Drive mechanisms 50 and 50 are provided on the coupling portion 22a of the first arm piece 22 of the first frame 21 and the coupling portion 42a of the third arm piece 42 of the second frame 41, respectively. Each of the drive mechanisms 50 and 50 includes a cam mechanism that regulates and holds the first and second frames 21 and 41 at predetermined positions, and a spring body that drives the cam mechanism, and the first and second frames 21 and 41 are provided. These frames are moved intermittently according to the rotation. Since the drive mechanisms provided in the first arm piece 22 and the third arm piece 42 have the same configuration, the same reference numerals are given, and the drive mechanism 50 attached to the first arm piece 22 is described below. Only explain.

カム機構は、第１結合部３４に設けられたカム３４ｂと、このカム３４ｂと噛合するカム５５ｂを一面に有する円盤状のカム板５５とからなる。このカム板５５には、その一端が筒状キャップ５１内に設けられたバネ体（図示省略）によって押圧されるバネ体押圧部５４が設けられ、他端がリンク機構６０に連結される棒状の作動棹６７に一体に固定されている。またカム板５５のバネ体押圧部５４は、その径が筒状キャップ５１の開口部の直径とほぼ同じ径及び所定の肉厚を有し、その内面、すなわち第１結合部３４の一面と対向する面に、複数個のカム５５ｂが作動棹６７から放射状に形成されている。また、このカム板５５は、第１結合部３４のカム３４ｂと噛合するようにカム５５ｂ同士の間に凹部５５ｃが設けられている。同様に、第１結合部３４の外面に設けられた複数個のカム３４ｂ同士の間にも凹部３４ｃが形成されている。また、筒状キャップ５１は鉤片５３により結合部２２ａの取付け穴２２ｂ内に固定され、カム板５５のバネ押圧部５４がこの筒状キャップ５１に固定されているため、このカム板５５は、第１フレーム２１の回動に伴って回動することとなる。なお、筒状キャップ５１の後端部は第１、第３アーム片２２、４２から突出しているが、この後端部は組立て時に送受話ケース２、１０の他方の隅部１５ａ、１６ａに収納される。   The cam mechanism includes a cam 34b provided in the first coupling portion 34 and a disc-shaped cam plate 55 having a cam 55b meshing with the cam 34b on one surface. The cam plate 55 is provided with a spring body pressing portion 54 whose one end is pressed by a spring body (not shown) provided in the cylindrical cap 51 and whose other end is connected to the link mechanism 60. It is integrally fixed to the operating rod 67. The spring body pressing portion 54 of the cam plate 55 has a diameter that is substantially the same as the diameter of the opening of the cylindrical cap 51 and a predetermined thickness, and faces the inner surface thereof, that is, one surface of the first coupling portion 34. A plurality of cams 55 b are formed radially from the operating rod 67 on the surface to be operated. Further, the cam plate 55 is provided with a recess 55c between the cams 55b so as to mesh with the cam 34b of the first coupling portion 34. Similarly, a recess 34 c is also formed between a plurality of cams 34 b provided on the outer surface of the first coupling portion 34. Further, the cylindrical cap 51 is fixed in the mounting hole 22b of the coupling portion 22a by the flange 53, and the spring pressing portion 54 of the cam plate 55 is fixed to the cylindrical cap 51. The first frame 21 rotates as the first frame 21 rotates. The rear end portion of the cylindrical cap 51 protrudes from the first and third arm pieces 22 and 42. The rear end portion is accommodated in the other corner portions 15a and 16a of the transmission / reception cases 2 and 10 when assembled. Is done.

互いのカム３４ｂ、５５ｂ同士は、携帯電話機１を開状態とする場合の角度に合わせて設けると好ましく、例えば携帯電話機１の開状態を１６０°とすれば、このカム同士の間隔も１６０°あるいはその半分の８０°毎に設けると、カムが噛合した時点で送受話ケース２、１０が固定されるため、開状態、閉状態あるいはその中間部での送受話ケース２、１０が安定する。   The cams 34b and 55b of each other are preferably provided in accordance with the angle when the mobile phone 1 is opened. For example, if the open state of the mobile phone 1 is 160 °, the interval between the cams is 160 ° or If it is provided at every half of 80 °, the transmission / reception cases 2 and 10 are fixed when the cams are engaged with each other, so that the transmission / reception cases 2 and 10 in the open state, the closed state, or an intermediate portion thereof are stabilized.

これにより、第１、第２フレーム２１、４１が回動されると、駆動機構５０のカム板５５が回動し、このカム板５５に設けられたカム５５ｂが、噛合された第１、第３結合部３４、３６のカム３４ｂ、３６ｂに乗り上げるように、バネ体の付勢力に抗して移動する。これにより、カム同士が噛合していない場合には適度な抵抗を生じるようになり、回動時のスナップアクションを実現する。   Thus, when the first and second frames 21 and 41 are rotated, the cam plate 55 of the drive mechanism 50 is rotated, and the cam 55b provided on the cam plate 55 is engaged with the first and second frames. It moves against the urging force of the spring body so as to ride on the cams 34b, 36b of the three coupling portions 34, 36. Thereby, when the cams are not meshed with each other, an appropriate resistance is generated, and a snap action at the time of rotation is realized.

次にリンク機構６０について説明する。   Next, the link mechanism 60 will be described.

リンク機構６０は、第１、第３アーム片２２、４２に設けられ、突出棒６５ａをその一面に有し第１、第３アーム片２２、４２の回動に連動して回動する一対のカム駒片６５と、連結部材３０の第１連結片３２に固定された規制板６３と、中心部に設けられた軸棒６１ａにより連結部材３０に回動可能に固定された長尺な棒状体からなり、規制板６３に設けられた規制穴６３ａ、６３ｂに連通された突出棒６５ａにその両端部が固定されて、第１、第３アーム片２２、４２の回動をリンクさせる作動バー６１と、を備え、駆動機構５０、５０のいずれか一方が駆動されたとき、他の駆動機構を連動させて作動させるものである。   The link mechanism 60 is provided on the first and third arm pieces 22 and 42, has a protruding bar 65 a on one surface thereof, and rotates in conjunction with the rotation of the first and third arm pieces 22 and 42. A long rod-like body rotatably fixed to the connecting member 30 by a cam piece 65, a restricting plate 63 fixed to the first connecting piece 32 of the connecting member 30, and a shaft bar 61a provided at the center. The operation bar 61 is configured to link the rotation of the first and third arm pieces 22 and 42 by fixing both ends thereof to the protruding rod 65a communicated with the restriction holes 63a and 63b provided in the restriction plate 63. And when either one of the drive mechanisms 50, 50 is driven, the other drive mechanisms are operated in conjunction with each other.

カム駒片６５は、作動棹６７の先端部に設けられた固定部材６８により第１、第３アーム片２２、４２に固定され、両アーム片に設けられた駆動機構５０、５０に連携されており、この固定部材６８の先端部には規制板６３の係止穴６４ａ、６４ｂに係止される小突起６９が設けられている。また、このカム駒片６５はほぼ半月状をなし、その内面の回転軸から所定距離離れた位置に規制板６３の規制穴６３ａ、６３ｂと係合する突出棒６５ａが形成されており、この突出棒６５ａはカム駒片６５の回動に合わせて円弧状に揺動する。   The cam piece 65 is fixed to the first and third arm pieces 22 and 42 by a fixing member 68 provided at the distal end portion of the operating rod 67, and is linked to the drive mechanisms 50 and 50 provided in both arm pieces. In addition, a small protrusion 69 that is locked to the locking holes 64 a and 64 b of the restriction plate 63 is provided at the tip of the fixing member 68. Further, the cam piece 65 has a substantially half-moon shape, and a protruding bar 65a that engages with the restriction holes 63a and 63b of the restriction plate 63 is formed at a position away from the rotation shaft on the inner surface thereof. The rod 65a swings in an arc shape in accordance with the rotation of the cam piece 65.

規制板６３は、第１連結片３２とほぼ同じ長さ及び幅長を有するほぼ楕円形の板状体からなり、この板状体の長手方向の両端部には固定部材６８の先端部に設けられた小突起６９が係止される係止穴６４ａ、６４ｂと、この係止穴を中心として所定角度に渡って屈曲して形成された細溝開口からなり、突出棒６５ａが挿入される規制穴６３ａ、６３ｂとが設けられている。規制穴６３ａ、６３ｂに挿入された突出棒６５ａはこの穴内で揺動可能であるとともに、その移動が所定位置で規制されるようになっている。   The restriction plate 63 is formed of a substantially elliptical plate-like body having substantially the same length and width as the first connecting piece 32, and is provided at both ends in the longitudinal direction of the plate-like body at the tip of the fixing member 68. A restriction hole 64a, 64b that is engaged with the small protrusion 69, and a narrow groove opening that is bent over a predetermined angle around the engagement hole and into which the protruding rod 65a is inserted. Holes 63a and 63b are provided. The protruding rod 65a inserted into the restriction holes 63a and 63b can swing within the holes, and its movement is restricted at a predetermined position.

作動バー６１は、規制板６３とほぼ同じ長さを有する棒状体からなり、両端部に長手方向に向かって所定長さのアソビを設けた楕円形の穴６２ａ、６２ｂが設けられており、この穴６２ａ、６２ｂにはカム駒片６５の突出棒６５ａが挿入される。   The actuating bar 61 is made of a rod-like body having substantially the same length as the restricting plate 63, and is provided with elliptical holes 62a, 62b provided with a predetermined length of play in the longitudinal direction at both ends. The protruding rod 65a of the cam piece 65 is inserted into the holes 62a and 62b.

上述の構成により、このリンク機構６０は、例えばヒンジ機構２０を開状態から閉状態へ第１フレーム２１を回動させることにより移行させると、回動された第１フレーム２１の回動に伴って第１アーム片２２に連結されたカム駒片６５が回動し、これによりカム駒片６５の突出棒６５ａが規制穴６３ａ内を右方から見て反時計方向に移動する。この移動に伴って作動バー６１の一端部の穴６２ａにも反時計方向の力が加わり、作動バー６１が軸棒６１ａを中心に時計方向に回動する。そして、作動バー６１の他端部の穴６２ｂに連結された、第３アーム片４２に連結したカム駒片６５の突出棒６５ａに時計方向の力が加わることによりこのカム駒片６５が時計方向に移動し、この移動に伴って第３アーム片４２が同じく時計方向に回動することにより、第１フレーム２１と第２フレーム４１とが互いに反対方向に回動するようになっている。なお、閉状態から開状態へ移行させる場合においても同様の動作がなされることは明白であるので、ここではその説明を省略する。   With the above-described configuration, when the link mechanism 60 is moved, for example, by rotating the first frame 21 from the open state to the closed state, the link mechanism 60 is accompanied by the rotation of the rotated first frame 21. The cam piece piece 65 connected to the first arm piece 22 rotates, whereby the protruding bar 65a of the cam piece piece 65 moves counterclockwise as viewed from the right in the restriction hole 63a. Along with this movement, a counterclockwise force is also applied to the hole 62a at one end of the operating bar 61, and the operating bar 61 rotates clockwise about the shaft bar 61a. Then, a clockwise force is applied to the protruding rod 65a of the cam piece 65 connected to the third arm piece 42 connected to the hole 62b at the other end of the operating bar 61, whereby the cam piece 65 is rotated clockwise. Accordingly, the third arm piece 42 similarly rotates clockwise in accordance with this movement, so that the first frame 21 and the second frame 41 rotate in directions opposite to each other. In addition, since it is clear that the same operation is performed in the case of shifting from the closed state to the open state, the description thereof is omitted here.

次に、図５〜図６を参照して、ヒンジ機構２０の組立てを説明する。   Next, the assembly of the hinge mechanism 20 will be described with reference to FIGS.

先ず、連結部材３０の第２結合部３３にそれぞれストッパー部材７１、７１を装着する。このストッパー部材７１の装着は、第２連結片３３の第１、第２結合部３５、３７に設けられた取付け穴３５ａ、３７ａにストッパー部材７１の第２取付け軸７３を挿通し、この取付け穴３５ａ、３７ａから抜けないようにこの軸の頂部をかしめる。なお、図５、図６は、すでにかしめた状態で図示している。   First, stopper members 71 and 71 are mounted on the second coupling portion 33 of the connecting member 30, respectively. The stopper member 71 is mounted by inserting the second mounting shaft 73 of the stopper member 71 through the mounting holes 35a and 37a provided in the first and second coupling portions 35 and 37 of the second connecting piece 33, The top of this shaft is caulked so as not to come out of 35a, 37a. 5 and 6 are already crimped.

一方、筒状キャップ５１を第１、第３アーム片２２、４２の取付け穴２２ｂ、４２ｂの内側から挿入し、筒状キャップ５１の鍔片５２を第１、第３アーム片２２、４２の溝２２ｃ、４２ｃに挿入して位置決めする。次いで、この筒状キャップ５１内にコイル状バネ体（図示省略）を挿入する。そして、この筒状キャップ５１内にカム板５５のバネ押圧部５４を挿入・固定し、次いで、連結部材３０と第１、第２フレーム２１、４１とを取付ける。この取付けは、バネ体により押圧されたカム板５５をバネ体に抗して押し込み、この状態で、第１及び第３アーム片２２、４２と第２及び第４アーム片２４、４４との間に連結部材３０の第１〜第４結合部３４〜３７を配置し、第２連結片３３の第２、第４結合部３５、３７に装着されたストッパー部材７１、７１の第１取付け軸７２、７２を第２、第４アーム片２４、４４の取付け穴２４ａ、４４ａに挿通して回り止めして取付けるとともに、ストッパー部材７１、７１の係止爪７１ａ、７１ｂを突起２５ａ、２５ｂ及び４５ａ、４５ｂに当接させて固定している。   On the other hand, the cylindrical cap 51 is inserted from the inside of the mounting holes 22b and 42b of the first and third arm pieces 22 and 42, and the flange piece 52 of the cylindrical cap 51 is inserted into the groove of the first and third arm pieces 22 and 42. Insert into 22c, 42c and position. Next, a coiled spring body (not shown) is inserted into the cylindrical cap 51. The spring pressing portion 54 of the cam plate 55 is inserted and fixed in the cylindrical cap 51, and then the connecting member 30 and the first and second frames 21 and 41 are attached. In this attachment, the cam plate 55 pressed by the spring body is pushed against the spring body, and in this state, between the first and third arm pieces 22 and 42 and the second and fourth arm pieces 24 and 44. The first to fourth coupling portions 34 to 37 of the coupling member 30 are arranged on the first coupling shaft 72 of the stopper members 71 and 71 mounted on the second and fourth coupling portions 35 and 37 of the second coupling piece 33. , 72 are inserted into the mounting holes 24a, 44a of the second and fourth arm pieces 24, 44 to prevent rotation, and the locking claws 71a, 71b of the stopper members 71, 71 are connected to the protrusions 25a, 25b, 45a, It is fixed in contact with 45b.

The cam 55 is engaged with the cam 55b of the cam plate 55. Subsequently, the cam piece 65 is attached to the operating rod 67. For this mounting, the cam piece 65 is inserted into the operating rod 67, a fixing member 68 is attached to the tip of the operating rod 67, and the cam piece 65 is fixed to the fixing member 68 to prevent rotation. Then, the shaft bar 61a of the actuating bar 61 is inserted into the fixing hole 38 through the insertion hole 64c of the restricting plate 63 and fixed in a freely rotatable manner, and then the locking holes 64a and 64b of the restricting plate 63 are fixed to the tip of the fixing member 68 Is inserted into the small projection 69 of the part.

FIG. 10 (a) shows a state where both cases are folded with the transmission / reception case of FIG. 1 cut from the line AA. 10 (b) is an enlarged side sectional view showing the hinge mechanism in the state of FIG. 10 (a), FIG. 11 shows a state where the transmission / reception case of FIG. 10 is opened by 80 °, and FIG. 11A is a side sectional view, FIG. 11B is an enlarged side sectional view showing the hinge mechanism in the state of FIG. 11A, FIG. 12 shows a state in which the transmission / reception case of FIG. (A) is a sectional side view, FIG.12 (b) is an expanded sectional side view which shows the hinge mechanism in the state of Fig.12 (a). In FIGS. 10A, 11A, and 12A, the link mechanism is omitted so that the shape of the housing at the connecting portion can be easily understood, and FIGS. 11 (b) and FIG. 12 (b) show the hinge mechanism 20 cut at a predetermined position so that the stopper member can be seen.

ヒンジ機構２０は、図１０（ａ）、図１１（ａ）及び図１２（ａ）に示すように、一対のほぼ半楕円形状のカバー部材７、８により、表面及び裏面から挟み込まれることで覆われており、送話ケース２と受話ケース１０との間に装着される。このカバー部材７、８は、長手方向の一側端部に鉤状の係止部７ａ、８ａが形成され、対向する他側短部に係止ねじ装着口７ｂ、８ｂが形成されており、係止部７ａ、８ａ同士を係止した状態で係止ねじ装着口７ｂ、８ｂ同士を連通させ、この連通させた係止ねじ装着口７ｂ、８ｂをねじ９によりねじ止めすることで取付けられている。このとき、係止ねじ装着口７ｂ、８ｂを半楕円形状の長手方向の側端部に設けることにより、送受話ケース２、１０の折畳み及び所定角度に開いた状態のいずれの状態においても、送話ケース２と受話ケース１０とからねじ９が露出することなく、すなわち外から見えないため美観を向上させることができる。   As shown in FIGS. 10 (a), 11 (a) and 12 (a), the hinge mechanism 20 is covered by being sandwiched between a pair of substantially semi-elliptical cover members 7 and 8 from the front surface and the back surface. It is attached between the transmission case 2 and the reception case 10. The cover members 7 and 8 are formed with hook-shaped locking portions 7a and 8a at one end portion in the longitudinal direction, and locking screw mounting ports 7b and 8b are formed at the other short side portions facing each other. The locking screw mounting ports 7b and 8b are communicated with each other while the locking portions 7a and 8a are locked to each other, and the connected locking screw mounting ports 7b and 8b are fixed by screws 9 with screws. Yes. At this time, by providing the locking screw mounting ports 7b and 8b at the side ends of the semi-elliptical longitudinal direction, the transmission / reception cases 2 and 10 are folded and opened at a predetermined angle. Since the screw 9 is not exposed from the talking case 2 and the receiving case 10, that is, cannot be seen from the outside, the aesthetic appearance can be improved.

送受話ケース２、１０を折畳んだ状態におけるヒンジ機構は、図７及び図１０（ｂ）に示すように、第１、第２フレーム２１、４１がほぼ平行状態となっている。すなわち、各ストッパー部材７１、７１のうち、第４連結部１０４に設けられたストッパー部材７１の係止爪７１ａが連結部材３０の第４結合部３７の係止突起３７ｂに当接し、また、第２連結部１０２に設けられたストッパー部材７１の係止爪７１ａは第２結合部３５の係止突起３５ｂから少し離れたところに位置している。すなわち、携帯電話機１を閉状態としたときにおいては、２つのストッパー部材７１の係止爪７１ａのうち、一方のみしか係止突起３７ｂに当接していない。これは、例えば携帯電話機１の送受話ケース２、１０の開閉角度を１６０°としたとき、ストッパー部材７１によって規制される開閉角度は、１６０°よりも若干（例えば１〜３°程度、すなわち１つの回動軸ごとに０．５〜１．５°程度）大きな角度が設定されていることを意味し、このようにストッパー部材７１により規制される角度を実際の開閉角度よりも大きな角度とすれば、例えば閉状態においてもストッパー部材７１によって規制されていないため、駆動機構５０により送話ケース２、受話ケース１０が互いに押し付けあうように付勢させた状態とすることができ、これにより、閉状態において送受話ケース２、１０間に隙間が生じることを防止することができる。なお、ここではストッパー部材７１、７１の一方が当接した場合について説明したが、両方のストッパー部材を僅かな隙間（回動軸を中心として０．５〜１．５°、好ましくは１°）を空けた状態とするようにしてもよい。この場合、送受話ケース２、１０の閉状態あるいは開状態においてはこの両ケース２、１０同士が当接することにより支持されるものである。   As shown in FIGS. 7 and 10B, the first and second frames 21 and 41 in the hinge mechanism in the state where the transmission / reception cases 2 and 10 are folded are in a substantially parallel state. That is, among the stopper members 71, 71, the locking claw 71 a of the stopper member 71 provided in the fourth connecting portion 104 abuts on the locking protrusion 37 b of the fourth coupling portion 37 of the connecting member 30, The locking claw 71 a of the stopper member 71 provided in the two connecting portions 102 is located at a distance from the locking projection 35 b of the second coupling portion 35. That is, when the cellular phone 1 is in the closed state, only one of the locking claws 71a of the two stopper members 71 is in contact with the locking projection 37b. For example, when the opening / closing angle of the transmission / reception cases 2 and 10 of the cellular phone 1 is 160 °, the opening / closing angle restricted by the stopper member 71 is slightly more than 160 ° (for example, about 1 to 3 °, ie, 1 This means that a large angle is set for each rotation axis, and the angle restricted by the stopper member 71 is set to be larger than the actual opening / closing angle. For example, since the stopper member 71 is not restricted even in the closed state, the transmission case 2 and the reception case 10 can be urged to be pressed against each other by the drive mechanism 50. It is possible to prevent a gap from being generated between the transmission / reception cases 2 and 10 in the state. In addition, although the case where one of the stopper members 71 and 71 abuts is described here, both the stopper members are slightly spaced (0.5 to 1.5 ° around the rotation axis, preferably 1 °). You may make it be in the state which opened. In this case, in the closed or open state of the transmission / reception cases 2 and 10, the two cases 2 and 10 are supported by contacting each other.

次いで、この折畳み状態から、一方のケース、例えば受話ケース１０を所定角度回動させると、他の送話ケース２も反対方向へ同じ角度回動する。例えば送受話ケース２、１０を図８及び図１１（ａ）に示すように８０°開くと、ヒンジ機構２０は、図１１（ｂ）に示すように、第１、第２フレーム２１、４１は、連結部材３０に対して互いに反対方向へほぼ同じ角度、すなわち４０°ずつ回動している。   Next, when one case, for example, the reception case 10 is rotated by a predetermined angle from this folded state, the other transmission case 2 is also rotated by the same angle in the opposite direction. For example, when the transmission / reception cases 2 and 10 are opened by 80 ° as shown in FIGS. 8 and 11A, the hinge mechanism 20 has the first and second frames 21 and 41 as shown in FIG. Rotate substantially the same angle, ie 40 °, in opposite directions with respect to the connecting member 30.

更に、送受話ケース２、１０を回動し、開状態となる１６０°にまで開くと、ヒンジ機構２０は、図９及び図１２（ｂ）に示すように、第１、第２フレーム２１、４１が連結部材３０に対して互いに８０°ずつ回動しており、また、１６０°開かれた状態では、送受話ケース２、１０の両隅部１５ａ、１５ｂ、１６ａ、１６ｂが当接することにより開状態を支持し、ストッパー部材７１、７１は係止突起３５ｂ、３７ｂに対して僅かな隙間（２°）を空けて位置している。ただし、開状態においては、このように僅かな隙間を設けることなく、送受話ケース２、１０を当接させるとともにストッパー部材７１、７１も係止突起３５ｂ、３７ｂに当接させるようにしてももちろん良い。   Further, when the transmission / reception cases 2 and 10 are rotated and opened to 160 °, which is in the open state, the hinge mechanism 20 has the first and second frames 21 and 21 as shown in FIG. 9 and FIG. 41 are rotated by 80 ° from each other with respect to the connecting member 30, and in a state of being opened 160 °, both corners 15 a, 15 b, 16 a, 16 b of the transmission / reception cases 2, 10 come into contact with each other. The open state is supported, and the stopper members 71 and 71 are positioned with a slight gap (2 °) with respect to the locking projections 35b and 37b. However, in the open state, the transmission / reception cases 2 and 10 are brought into contact with each other and the stopper members 71 and 71 are also brought into contact with the locking projections 35b and 37b without providing such a small gap. good.

図１３は図１０（ａ）のＢ方向からみた側面図である。この図に示すように、ヒンジ機構２０がカバー部材７、８で覆われると、送受話ケース２、１０の各隅部１５ａ、１５ｂ及び１６ａ、１６ｂにより挟まれたヒンジ機構２０が連結される隙間の幅方向の長さが、ヒンジカバーＣを構成するカバー部材７、８の幅方向よりも長くなっており、カバー部材７、８の側端と送受話ケース２、１０の各隅部１５ａ、１５ｂ及び１６ａ、１６ｂとの間には所定長さｄの小隙間が形成される。この位置に隙間が形成されると、送受話ケース２、１０の折畳み時に、送受話ケース２、１０とカバー部材７、８とが擦れて摩擦音、例えばきしみ音が発生することがなくなる。なお、この小隙間は塵等が侵入しないような構造とすると好ましい。   FIG. 13 is a side view seen from the direction B in FIG. As shown in this figure, when the hinge mechanism 20 is covered with the cover members 7 and 8, the gap where the hinge mechanism 20 sandwiched between the corners 15a, 15b and 16a, 16b of the transmission / reception cases 2, 10 is connected. In the width direction is longer than the width direction of the cover members 7 and 8 constituting the hinge cover C, and the side edges of the cover members 7 and 8 and the corners 15a of the transmission and reception cases 2 and 10, A small gap of a predetermined length d is formed between 15b and 16a, 16b. If a gap is formed at this position, when the transmission / reception cases 2 and 10 are folded, the transmission / reception cases 2 and 10 and the cover members 7 and 8 are not rubbed to generate a frictional sound such as a squeak noise. It is preferable that the small gap has a structure that does not allow dust or the like to enter.

上述したように、実施例のヒンジ機構は、リンク機構６０により、第１、第２フレーム２１、４１の回動が連結部材３０に対して逆位相で連係して駆動するため、一方のフレームのみが回動することはなく、常に両フレームの回動が連係するため、安定した開閉動作を実現できるとともに、閉状態における送受話ケース２、１０にズレが生じることもない。   As described above, the hinge mechanism of the embodiment is driven by the link mechanism 60 so that the rotation of the first and second frames 21 and 41 is linked with the connecting member 30 in the opposite phase. Since the rotation of both frames is always linked, a stable opening / closing operation can be realized and the transmission / reception cases 2 and 10 in the closed state are not displaced.

なお、この実施例では、駆動機構５０を第１、第３連結部１０１、１０３の２箇所に設けたが、第１〜第４連結部１０１〜１０４の何れにいくつ設けてもよい。ただし、駆動機構５０を１つのみとすると、バックラッシが原因となるアソビあるいはガタが発生するため、好ましくは回動軸ごとに１つずつ設けるものとする。また、リンク機構６０は駆動機構５０が設けられた第１、第３連結部１０１、１０３に設けられているが、第１フレーム２１と第２フレーム４１とをリンクさせることが可能であれば何れに設けてもよく、好ましくは第１アーム片２２と第３アーム片４２、又は第２アーム片２４と第４アーム片４４とをリンクするように設けると最も省スペースで設置することができる。   In this embodiment, the drive mechanism 50 is provided at two locations of the first and third connecting portions 101 and 103, but any number of drive mechanisms 50 may be provided at any of the first to fourth connecting portions 101 to 104. However, if there is only one drive mechanism 50, since play or backlash due to backlash occurs, it is preferable to provide one for each rotating shaft. In addition, the link mechanism 60 is provided in the first and third connecting portions 101 and 103 provided with the drive mechanism 50. Any link mechanism 60 can be used as long as the first frame 21 and the second frame 41 can be linked. Preferably, the first arm piece 22 and the third arm piece 42, or the second arm piece 24 and the fourth arm piece 44 are provided so as to be linked with each other, so that the most space-saving installation can be achieved.

また、上記実施例では、リンク機構６０としてカム駒片６５、６５及び作動バー６１とを用いた場合について説明したが、これに限らず、例えば第１、第２フレーム２１、４１のいずれか一方のアーム片に固定された一対の歯車と、この両歯車間に設けられてこの歯車同士を連結駆動するための偶数個の遊歯車と、によってリンク機構６０を構成しても良い。   In the above embodiment, the case where the cam piece pieces 65 and 65 and the operation bar 61 are used as the link mechanism 60 has been described. However, the present invention is not limited to this, and for example, one of the first and second frames 21 and 41. The link mechanism 60 may be configured by a pair of gears fixed to the arm piece and an even number of free gears provided between the gears for connecting and driving the gears.

加えて、本実施例ではストッパー機構７０、７０のみが設けられた第２、第４連結部１０２、１０４上に連結配線（ＦＰＣ６）が設けられている。これはＦＰＣ６の周囲にストレスを許容するためのスペースを取りやすいためにこのような位置に設けられたものであるが、この位置に限定したものではなく、何れの連結部上に配線してもよい。ただし、好ましくは各種機構ができるだけ設けられていない連結部に設けるとよく、また第１、第２連結部と第３、第４連結部のうち近接して対向する連結部に配線するとＦＰＣ６自体の長さを短縮できるとともに捩れ等を良好に阻止できる。   In addition, in the present embodiment, the connection wiring (FPC 6) is provided on the second and fourth connection portions 102 and 104 where only the stopper mechanisms 70 and 70 are provided. This is provided in such a position because it is easy to take a space around the FPC 6 to allow stress, but it is not limited to this position. Good. However, it is preferable to provide it in a connecting portion where various mechanisms are not provided as much as possible, and if the wiring is connected to a connecting portion that is close and opposed among the first and second connecting portions and the third and fourth connecting portions, the FPC 6 itself The length can be shortened and twisting and the like can be satisfactorily prevented.

また、ストッパー機構７０についても実施例では第２、第４連結部１０２、１０４に設けたが、何れの連結部に何個設けても良いが、好ましくは駆動機構と同様に回転軸ごと１つずつ設けるものとする。また、このストッパー機構７０を駆動機構５０及びリンク機構６０が設けられた連結部であっても設けることができることは当業者にとり自明であろう。   In the embodiment, the stopper mechanism 70 is also provided in the second and fourth connecting portions 102 and 104. However, any number of stopper mechanisms 70 may be provided in any of the connecting portions, but preferably one for each rotating shaft as in the driving mechanism. It shall be provided one by one. It will be apparent to those skilled in the art that the stopper mechanism 70 can be provided even in a connecting portion provided with the drive mechanism 50 and the link mechanism 60.
