図示のように、固定部６０には、リンク６１及びピン６２・６３を介してヒンジ軸６４が連結されている。すなわち、固定部６０にリンク６１の一端がピン６２で連結されて、リンク６１の他端がピン６３でヒンジ軸６４の偏心位置に連結されている。また、ヒンジ軸６４の左右端の同軸上に一対のスライド部６５・６６が相対回転自在に連結されている。   As shown in the figure, a hinge shaft 64 is connected to the fixed portion 60 via a link 61 and pins 62 and 63. That is, one end of the link 61 is connected to the fixed portion 60 by the pin 62, and the other end of the link 61 is connected to the eccentric position of the hinge shaft 64 by the pin 63. Further, a pair of slide portions 65 and 66 are connected to be coaxial with the left and right ends of the hinge shaft 64 so as to be relatively rotatable.

一対のスライド部６５・６６は、固定部６０の左右のレール６０ａに沿って係合溝６５ａ・６６ａをスライド自在に組み付けて、凹凸結合部６５ｂ・６６ｂで一体化結合される。そして、ヒンジ軸６４の周囲には、トルク発生部６７及び圧入部６８が組み付けられて、ワッシャ６９により抜け止めされている。なお、トルク発生部６７は、図示しないクリック発生部と圧縮コイルバネ及びワッシャを内蔵して構成される。   The pair of slide portions 65 and 66 are integrally coupled by the concave and convex coupling portions 65b and 66b with the engagement grooves 65a and 66a being slidably assembled along the left and right rails 60a of the fixed portion 60. A torque generating portion 67 and a press-fit portion 68 are assembled around the hinge shaft 64 and are prevented from being detached by a washer 69. The torque generating unit 67 is configured by incorporating a click generating unit (not shown), a compression coil spring, and a washer.

図７は左のヒンジユニット７の構成部品を分解したもので、７０は固定部、７１はスライド部、７２は中空軸、７３は圧入部、７４はワッシャである。   FIG. 7 is an exploded view of the components of the left hinge unit 7. Reference numeral 70 denotes a fixing portion, 71 denotes a slide portion, 72 denotes a hollow shaft, 73 denotes a press-fit portion, and 74 denotes a washer.

図示のように、固定部７０の左右のレール７０ａに沿ってスライド部７１の係合溝７１ａがスライド自在に組み付けられている。スライド部７１は、中空軸７２に相対回転自在に連結されている。そして、中空軸７２の周囲には、圧入部７３が組み付けられて、ワッシャ７４により抜け止めされている。   As shown in the drawing, the engagement grooves 71a of the slide portion 71 are slidably assembled along the left and right rails 70a of the fixed portion 70. The slide portion 71 is connected to the hollow shaft 72 so as to be relatively rotatable. A press-fit portion 73 is assembled around the hollow shaft 72 and is prevented from being detached by a washer 74.

以上、左右のヒンジユニット６・７において、固定部６０・７０が第１筐体１の内部にそれぞれネジ止めして一体化されて、圧入部６８・７３が第２筐体２のヒンジボス２０内にそれぞれ圧入して一体化される。   As described above, in the left and right hinge units 6 and 7, the fixing portions 60 and 70 are integrated by screwing into the first housing 1, and the press-fit portions 68 and 73 are integrated in the hinge boss 20 of the second housing 2. Each is press-fitted into and integrated.

図８及び図１０は右ヒンジユニット６の作用を説明するもので、図８（ａ）及び図１０（ａ）に示す閉じた状態において、第１筐体１と第２筐体２を開くと、第２筐体２のヒンジボス２０内に圧入した圧入部６８と一体化されたヒンジ軸６４の回転により、その偏心位置にピン６３で連結したリンク６１が、固定部６０に連結されたピン６２を支点に揺動する。   8 and 10 illustrate the operation of the right hinge unit 6. When the first housing 1 and the second housing 2 are opened in the closed state shown in FIGS. 8 (a) and 10 (a). The link 61 connected to the eccentric position by the pin 63 by the rotation of the hinge shaft 64 integrated with the press-fit portion 68 press-fitted into the hinge boss 20 of the second housing 2 is connected to the fixed portion 60. Swing around the fulcrum.

このとき、固定部６０に連結されたピン６２を支点とするリンク６１の揺動によって、ピン６３を介して連結したヒンジ軸６４の同軸上に相対回転自在に連結されたスライド部６５・６６が、固定部６０のレール６０ａに沿って係合溝６５ａ・６６ａでスライド移動して、図８（ｂ）及び図１０（ｂ）に示す中間状態を経て図８（ｃ）及び図１０（ｃ）に示す開いた状態になる。   At this time, the slide portions 65 and 66 that are rotatably connected on the same axis as the hinge shaft 64 that is connected via the pin 63 by the swing of the link 61 that uses the pin 62 that is connected to the fixed portion 60 as a fulcrum. 8C and FIG. 10C through the intermediate state shown in FIGS. 8B and 10B by sliding along the rails 60a of the fixing portion 60 in the engagement grooves 65a and 66a. It will be in the open state shown in.

以上の結果、ヒンジ軸６４は回転と同時にスライドする。つまり、ヒンジ軸６４の回転角によりスライド位置が一義的に決まる。   As a result, the hinge shaft 64 slides simultaneously with the rotation. That is, the slide position is uniquely determined by the rotation angle of the hinge shaft 64.

このような右ヒンジユニット６の動作と同期して左ヒンジユニット７も連動する。すなわち、第２筐体２のヒンジボス２０内に圧入した圧入部７３と一体化された中空軸７２に相対回転自在に連結したスライド部７１が、固定部７０のレール７０ａに沿って係合溝７１ａでスライド移動する。   The left hinge unit 7 is also interlocked with the operation of the right hinge unit 6 in this manner. That is, the slide portion 71 connected to the hollow shaft 72 integrated with the press-fit portion 73 press-fitted into the hinge boss 20 of the second housing 2 is relatively rotatable along the rail 70 a of the fixed portion 70. Move the slide with.

以上の構成による右ヒンジユニット６及び左ヒンジユニット７を、第１筐体１と第２筐体２を閉じた状態において、図２に示すように、両筐体１・２内に収納した状態に組み付けてヒンジカバー５で覆った状態にする。なお、ヒンジ軸６４は、閉じた状態の第１筐体１と第２筐体２の厚み方向中心付近の高さに位置している。また、開閉時の干渉を回避するため、第１筐体１もしくは第２筐体２のヒンジ側端部は切り欠き形状となっており、図２及び図３の例では、第２筐体２のヒンジ側端部が斜めの切り欠き形状となっている。   The state in which the right hinge unit 6 and the left hinge unit 7 configured as described above are housed in both the housings 1 and 2 as shown in FIG. 2 with the first housing 1 and the second housing 2 closed. And is covered with the hinge cover 5. The hinge shaft 64 is positioned at a height near the center in the thickness direction of the closed first housing 1 and second housing 2. Moreover, in order to avoid interference at the time of opening and closing, the hinge side end portion of the first housing 1 or the second housing 2 has a notch shape. In the example of FIGS. The hinge side end portion is an oblique cutout shape.

図１１（ａ）は両筐体１・２の開く中間状態を示し、図１１（ｂ）はそのヒンジカバー５を外したもので、図１２（ａ）は図１１の両筐体１・２の背面側を示し、図１２（ｂ）はそのヒンジカバー５を外したもので、図１３は図１１の両筐体１・２を透視してヒンジユニット６を示したものである。   FIG. 11A shows an intermediate state in which both housings 1 and 2 are opened, FIG. 11B shows the case where the hinge cover 5 is removed, and FIG. 12A shows both housings 1 and 2 in FIG. FIG. 12B shows the hinge unit 5 with the hinge cover 5 removed, and FIG. 13 shows the hinge unit 6 seen through the two housings 1 and 2 in FIG.

また、図１４は図１の両筐体１・２の開いた状態を示し、図１５はその両筐体１・２を透視してヒンジユニット６・７及び配線８を示したもので、図示のように、左のヒンジユニット７の中空軸７２の中空部に、第１筐体１の操作部３と第２筐体２の表示部４とを電気的に接続する同軸細線による配線８を通している。   14 shows a state in which both the housings 1 and 2 of FIG. 1 are opened, and FIG. 15 shows the hinge units 6 and 7 and the wiring 8 through the both housings 1 and 2. As shown in the figure, through the hollow portion of the hollow shaft 72 of the left hinge unit 7, the coaxial thin wire 8 is used to electrically connect the operation unit 3 of the first housing 1 and the display unit 4 of the second housing 2. Yes.

以上、実施形態の折り畳み式携帯電話によれば、両筐体１・２を開放させるのに伴って、ヒンジ軸６４を両筐体１・２内からスライドさせて引き出すスライド部６５・６６を備え、具体的には、ヒンジ軸６４が第２筐体２と一体に回転するのに連動して、スライド部６５・６６をスライドさせるリンク６１を備えることで、両筐体１・２を閉じた状態において、ヒンジカバー５が若干突出するだけで、回転ヒンジが内部に収納されているので目立たなくなっている。
また、閉じた状態の第１筐体１と第２筐体２の厚み方向中心付近の高さにヒンジ軸６４を持ってくることにより、両筐体１・２を開いた状態において、筐体１・２同士に段差が生じることもない。 As described above, according to the foldable mobile phone of the embodiment, the slide parts 65 and 66 are provided to slide out the hinge shaft 64 from both the casings 1 and 2 as the casings 1 and 2 are opened. Specifically, the two housings 1 and 2 are closed by providing the link 61 for sliding the slide portions 65 and 66 in conjunction with the hinge shaft 64 rotating integrally with the second housing 2. In this state, the hinge cover 5 is only slightly protruded and is not noticeable because the rotary hinge is housed inside.
Further, by bringing the hinge shaft 64 to a height near the center in the thickness direction of the first casing 1 and the second casing 2 in the closed state, the casings 1 and 2 can be opened in the opened state. There is no difference in level between the two.
