本発明は、第１筐体および第２筐体が連結部により、折り畳み可能に連結された携帯端末に関する。 The present invention relates to a mobile terminal in which a first housing and a second housing are connected to each other by a connecting portion so as to be foldable.

携帯電話などの携帯端末において、従来より２つの筐体が連結部を介して回動自在に連結された折りたたみ式タイプのものが広く普及している。例えば、下筐体（第１筐体）は、携帯端末を使用する際に、使用者が手で保持するもので、表面に入力キーおよび機能キーを多数備えた操作部が設けられており、上筐体（第２筐体）には、表面に表示部（ＬＣＤ）が設けられているものが知られている。
一方、特許文献１によれば、下筐体と上筐体とは連結部を介して回動可能に接続されている。連結部は、互いに直交する方向の第１回動軸および第２回動軸を有しており、下筐体には第２回動軸を回動可能に支持する軸通し部が設けられ、上筐体には第１回動軸を回動可能に支持する軸通し部が設けられているものが開示されている。 2. Description of the Related Art Conventionally, in a portable terminal such as a mobile phone, a foldable type in which two casings are rotatably connected via a connecting portion has been widely used. For example, the lower housing (first housing) is held by the user's hand when using the mobile terminal, and has an operation unit provided with a large number of input keys and function keys on the surface. An upper casing (second casing) having a display unit (LCD) on the surface is known.
On the other hand, according to Patent Document 1, the lower housing and the upper housing are connected to each other via a connecting portion so as to be rotatable. The connecting portion has a first rotation shaft and a second rotation shaft in directions orthogonal to each other, and a shaft through portion that rotatably supports the second rotation shaft is provided in the lower housing. An upper casing is disclosed which is provided with a shaft passing portion that rotatably supports a first rotation shaft.

この携帯端末によれば、上筐体および下筐体を閉じた状態から第１回動軸を中心として上筐体を下筐体に対して回動させることで、いわゆる縦開きの操作が可能になる。このとき、第１回動軸の先端に設けられているロックツメが下筐体の上面に設けられているロック穴に嵌合してロックされている。一方、上筐体および下筐体を閉じた状態から第２回動軸を中心として上筐体を下筐体に対して回動させることで、いわゆる横開きの操作が可能である。このとき、上筐体の先端に設けられているロックツメが、第２回動軸の先端のヒンジ（軸受）に設けられているロック穴にロックされるとともに、第１回動軸のロックツメは、下筐体の上面に設けられているロック穴から解放されることになる。

In the closed state where the first housing and the second housing overlap each other, the first engaging portion and the second engaging portion are In a state where the second casing is not locked and rotated around the second rotation axis, the first engagement portion protrudes by the magnetic force of the magnet, and the first engagement portion and the In the transition state between the opened state and the closed state, the second projecting portion is accommodated in the second accommodating portion. In state, it rotates about the axis of the second housing section and the first projecting portion along the inclined surface of, characterized in that out of the second container.

ここで、第１回動軸および第２回動軸とは、第１筐体および第２筐体が閉じ状態から縦開き状態あるいは横開き状態に移行する際の第１筐体および第２筐体の回転中心線の方向を指す。
一方、第１回動部材および第２回動部材とは、第１筐体に対して第２筐体が回転するための支軸としての部材であり、第１筐体に対する第２筐体の回転に伴って当該第１回動部材あるいは第２回動部材が軸まわりに回転する。 Here, the first rotating shaft and the second rotating shaft are the first housing and the second housing when the first housing and the second housing shift from the closed state to the vertically opened state or the horizontally opened state.

And the second housing is rotated about the second rotation axis, whereby the second protruding portion is accommodated in the second accommodating portion and the engagement pin is locked. In addition, since the second projecting portion can be rotated about the axis of the first projecting portion, the engagement is insufficient when the engagement pin does not project sufficiently or the second projecting portion is not in a predetermined position. In the combined state, when an external force that moves the second housing relative to the first housing is applied, the engagement pin comes out of the second engagement portion. There is an effect that damage around the second engaging portion in the housing can be prevented.

A substantially cylindrical second protrusion 52 extending in a direction intersecting the continuous direction of the first protrusion 51. Therefore, the engagement pin 45 has a shape in which the first protrusion 51 and the second protrusion 52 are integrally connected in a substantially L shape. Further, the engagement pin 45 can be rotated by a predetermined angle (18 degrees to the left and right) around the axis of the first protrusion 51.
The engagement pin 45 is formed of a magnetic material, and the tip (open end) of the second protrusion 52 faces the side opposite to the connecting portion 13, that is, the longitudinal direction end 37 of the lower housing 11. The second projecting portion 52 can project from the lower housing 11 to a position along the second rotation shaft 32.

保持部４９は、下筐体１１の内部に収容されて固定されているとともに、係合ピン４５の第１突出部５１に挿通されている。係合ピン４５を前述したように所定角度だけ回動可能に保持するため、第１突出部５１を円形断面とするとともにストッパを設けて、所定角度回動可能とすることができる。あるいは、第１突出部５１を矩形断面とし、保持部において第１突出部５１を支持する穴の形状を、所定角度分矩形断面が回動可能な円形断面とすることもできる。
なお、係合ピン４５は、第２突出部５２の先端が操作部２３に近付くように回動することが望ましい。 The holding portion 49 is housed and fixed inside the lower housing 11, and is inserted through the first protruding portion 51 of the engagement pin 45. Since the engagement pin 45 is rotatably held by a predetermined angle as described above, the first projecting portion 51 can have a circular cross section, and a stopper can be provided so that the engagement pin 45 can be rotated by a predetermined angle. Or the 1st protrusion part 51 can be made into a rectangular cross section, and the shape of the hole which supports the 1st protrusion part 51 in a holding | maintenance part can also be made into the circular cross section which can rotate a rectangular cross section by a predetermined angle.
Note that the engagement pin 45 is preferably rotated so that the tip of the second projecting portion 52 approaches the operating portion 23.

この構成によれば、係合ピン４５を回動させる外力が作用した場合、第２突出部５２が第２係合部４６によりロックされる側（すなわち、第２収容部５６側）と反対方向へ回動するので、係合ピン４５は第２係合部４６から外れやすくなる。 According to this configuration, when an external force that rotates the engaging pin 45 is applied, the direction opposite to the side where the second projecting portion 52 is locked by the second engaging portion 46 (that is, the second accommodating portion 56 side). Therefore, the engagement pin 45 is easily detached from the second engagement portion 46.

図１３（Ａ）〜（Ｃ）に示すように、上筐体１２が第１回動軸３１を中心に回動して開いた状態（すなわち、縦開き状態）において、係合ピン４５の第２突出部５２が突出しないように収容する凹部４９Ｅを設けるとともに、凹部４９Ｅの底部に第２突出部５２を安置する凹状の安置面４９Ｅを設けるのが望ましい。なお、凹部４９Ｅの内側が底部に向かって第２突出部５２を案内する傾斜面４９Ｇとなるようにする。 As shown in FIGS. 13A to 13C, in the state where the upper housing 12 is rotated about the first rotation shaft 31 and opened (that is, in the vertically opened state), It is desirable to provide the recessed part 49E which accommodates so that the 2 protrusion part 52 may not protrude, and to provide the concave seating surface 49E which rests the 2nd protrusion part 52 in the bottom part of the recessed part 49E. The inner side of the recess 49E is an inclined surface 49G that guides the second protrusion 52 toward the bottom.

これにより、上筐体１２が第１回動軸３１を中心として回動する際には、係合ピン４５は第２係合部４６に係合しないので、係合ピン４５を凹部４９Ｅに収容して係合ピン４５が下筐体１１の表面１１Ａから突出しないようにする。このとき、凹部４９Ｅの底部に安置面４９Ｆを設け、凹部４９Ｅの内面に第２突出部５２を案内する傾斜面４９Ｇを設けたので、回動可能な第２突出部５２を確実に収容することができる。 Thus, when the upper housing 12 rotates about the first rotation shaft 31, the engagement pin 45 is not engaged with the second engagement portion 46, so that the engagement pin 45 is accommodated in the recess 49E. Thus, the engagement pin 45 is prevented from protruding from the surface 11A of the lower housing 11. At this time, the rest surface 49F is provided at the bottom of the recess 49E, and the inclined surface 49G for guiding the second protrusion 52 is provided on the inner surface of the recess 49E, so that the rotatable second protrusion 52 can be reliably accommodated. Can do.

図９に示すように、係合ピン４５は、保持部４９に挿通した状態で、第１突出部５１の基端部、すなわち第１突出部５１における第２突出部５２との接続箇所とは反対側の端部にストッパ５０が設けられている。ストッパ５０は、金属性の筒形状とされ、第１突出部５１の基端部に挿通されて固定されている。
なお、ストッパ５０は、係合ピン４５が磁性体であれば、金属以外の非磁性体であってもよい。 As shown in FIG. 9, the engagement pin 45 is inserted into the holding portion 49 and is a base end portion of the first protruding portion 51, that is, a connection portion with the second protruding portion 52 in the first protruding portion 51. A stopper 50 is provided at the opposite end. The stopper 50 has a metallic cylindrical shape, and is inserted into and fixed to the proximal end portion of the first protruding portion 51.
The stopper 50 may be a non-magnetic material other than metal as long as the engagement pin 45 is a magnetic material.

このような係合ピン４５は、保持部４９の上面４９Ａの安置面４９Ｆに第２突出部５２が接触する位置から、保持部４９の下面４９Ｂにストッパ５０が接触する位置までの範囲で、第１突出部５１の軸方向に沿って保持部４９に対して摺動可能となっている。
そして、係合ピン４５は、保持部４９の上面４９Ａに第２突出部５２が接触する位置にあるときは第１突出部５１の頂部および第２突出部５２が下筐体１１の表面１１Ａから突出せず、保持部４９の下面４９Ｂにストッパ５０が接触する位置にあるときは第２突出部５２の軸線が第２回動軸３２に沿うように配置される。 Such an engagement pin 45 is in a range from a position where the second protrusion 52 contacts the resting surface 49F of the upper surface 49A of the holding portion 49 to a position where the stopper 50 contacts the lower surface 49B of the holding portion 49. It can slide with respect to the holding portion 49 along the axial direction of the one protruding portion 51.
When the second protrusion 52 is in a position where the engagement pin 45 is in contact with the upper surface 49 A of the holding part 49, the top of the first protrusion 51 and the second protrusion 52 are separated from the surface 11 A of the lower housing 11. When the stopper 50 is in a position where it does not protrude and contacts the lower surface 49 B of the holding part 49, the axis of the second protrusion 52 is arranged along the second rotation shaft 32.

下筐体磁石４８は、下筐体１１の内部において第１突出部５１の軸方向に沿った係合ピン４５の直下に配置されている。図１０（Ａ）に示すように、この下筐体磁石４８は、保持部４９の上面４９Ａに第２突出部５２が接触する位置にあるとき、すなわち係合ピン４５が下筐体１１に収容されているとき、ストッパ５０に対して間隔Ｓ１を介して接触しない位置に配置されている。 The lower housing magnet 48 is disposed directly below the engagement pin 45 along the axial direction of the first protrusion 51 inside the lower housing 11. As shown in FIG. 10A, when the lower casing magnet 48 is in a position where the second protrusion 52 contacts the upper surface 49A of the holding section 49, that is, the engaging pin 45 is accommodated in the lower casing 11. When it is, it is arranged at a position where it does not contact the stopper 50 via the interval S1.

このような下筐体磁石４８は、表面に板金４８Ａが積層されているため、板金４８Ａの材質、厚み、面積等を適宜選択することにより係合ピン４５に対する当該下筐体磁石４８の磁力を任意に設定できる。 Since such a lower casing magnet 48 has a sheet metal 48A laminated on its surface, the magnetic force of the lower casing magnet 48 with respect to the engagement pin 45 can be selected by appropriately selecting the material, thickness, area, etc. of the sheet metal 48A. Can be set arbitrarily.

第２係合部４６は、携帯端末１０が閉じ状態にあるとき、前述した第１係合部である係合ピン４５と対面する位置において、下筐体１１から突出した係合ピン４５の第１突出部５１を挿入可能な第１収容部５５（図５、図６、図９参照）と、下筐体１１から突出した係合ピン４５の第２突出部５２を挿入する第２収容部５６（図５、図６、図１０参照）とを有する。
第２係合部４６は、第１収容部５５および第２収容部５６が上筐体１２の長手方向に沿って配列され、第１収容部５５が連結部１３に近い位置に配置されている。 When the mobile terminal 10 is in the closed state, the second engagement portion 46 is the first of the engagement pins 45 protruding from the lower housing 11 at a position facing the engagement pin 45 that is the first engagement portion described above. A first accommodating portion 55 (see FIGS. 5, 6, and 9) into which the first protruding portion 51 can be inserted, and a second accommodating portion into which the second protruding portion 52 of the engagement pin 45 protruding from the lower housing 11 is inserted. 56 (see FIGS. 5, 6, and 10).
In the second engaging portion 46, the first housing portion 55 and the second housing portion 56 are arranged along the longitudinal direction of the upper housing 12, and the first housing portion 55 is disposed at a position close to the connecting portion 13. .

図８および図９に示すように、第１収容部５５は、所定厚みを有する扇状の肉抜部５５Ｂにより略矩形状の開口５８Ａと略Ｖ字状の開口５８Ｂとを有するブロック体とされ、開口５８Ａが上筐体１２の表面１２Ａに沿うように設けられている（図６参照）。
開口５８Ｂと反対側に形成された軸部５９は、その軸線が開口５８Ｂの円弧中心を通過するように配置されている。肉抜部５５Ｂの内面５８は平滑面となっている。 As shown in FIGS. 8 and 9, the first accommodating portion 55 is a block body having a substantially rectangular opening 58 A and a substantially V-shaped opening 58 B by a fan-shaped hollow portion 55 B having a predetermined thickness. An opening 58A is provided along the surface 12A of the upper housing 12 (see FIG. 6).
The shaft portion 59 formed on the side opposite to the opening 58B is disposed such that the axis passes through the arc center of the opening 58B. The inner surface 58 of the lightening part 55B is a smooth surface.

この第１収容部５５は、肉抜部５５Ｂの周囲に上筐体磁石（磁石）６３がインサート成型により埋設されているとともに、開口の周囲に円弧状の案内溝５５Ａが形成されている。上筐体磁石６３としては、前述した下筐体磁石４８よりも磁力が大きい磁石が採用されている。案内溝５５Ａは、その円弧中心が軸部５９の軸線に沿うように配置されている。このような第１収容部５５は、軸部５９の軸線が第２回動軸３２に沿うように配置されているとともに、軸部５９に軸通される捻りばねであるリターンスプリング４７により、
開口５８Ａが常に上筐体１２の表面１２Ａに沿うように維持される。 In the first housing 55, an upper casing magnet (magnet) 63 is embedded by insert molding around the thinned portion 55B, and an arcuate guide groove 55A is formed around the opening. As the upper casing magnet 63, a magnet having a larger magnetic force than the above-described lower casing magnet 48 is employed. The guide groove 55 A is disposed so that the center of the arc is along the axis of the shaft portion 59. Such a first accommodating portion 55 is arranged so that the axis of the shaft portion 59 is along the second rotation shaft 32, and by a return spring 47 that is a torsion spring that is passed through the shaft portion 59,
The opening 58 A is always maintained along the surface 12 A of the upper housing 12.

図７、図８、図１０に示すように、第２収容部５６は、略Ｕ字状の肉抜部５６Ｂにより略矩形状の開口５６Ｃと略Ｕ字状の開口５６Ｄとを有するブロック状とされ、開口５６Ｄの周囲に突起５６Ａが設けられている。突起５６Ａは、第１収容部５５の案内溝５５Ａに差し込まれる。
この第２収容部５６は、第１収容部５５に隣接して配置され、開口５６Ｃが上筐体１２の表面１２Ａに沿うように上筐体１２に固定されている。 As shown in FIGS. 7, 8, and 10, the second storage portion 56 has a block shape having a substantially rectangular opening 56 C and a substantially U-shaped opening 56 D by a substantially U-shaped thinning portion 56 B. A projection 56A is provided around the opening 56D. The protrusion 56 A is inserted into the guide groove 55 A of the first housing portion 55.
The second housing portion 56 is disposed adjacent to the first housing portion 55, and is fixed to the upper housing 12 so that the opening 56 C is along the surface 12 A of the upper housing 12.

以上のような第２係合部４６は、リターンスプリング４７により第１収容部５５の開口５８Ａが上筐体１２の表面１２Ａに沿うように維持されるため、通常、第１収容部５５の開口５８Ａと第２収容部５６の開口５６Ｃとが上筐体１２の表面１２Ａに沿って連続するように配向される。 Since the second engaging portion 46 as described above is maintained by the return spring 47 so that the opening 58A of the first housing portion 55 is along the surface 12A of the upper housing 12, the opening of the first housing portion 55 is usually provided. 58A and the opening 56C of the second housing portion 56 are oriented so as to be continuous along the surface 12A of the upper housing 12.

図１４（Ａ）、（Ｂ）および図７（Ｂ）に示すように、第２収容部５６における第１収容部５５側の開口縁部であって、かつ、上筐体１２の側端面側に傾斜面５６Ｅを設けるのが望ましい。
これにより、係合ピン４５と第２係合部４６とが適正に係合していない場合には、係合ピン４５の第２突出部５２を収容する第２収容部５６に設けられている傾斜面５６Ｅに沿って第２収容部５６から外れることができる。なお、傾斜面５６Ｅの角度は、限定するものではない。 As shown in FIGS. 14A, 14B, and 7B, it is an opening edge portion on the first housing portion 55 side in the second housing portion 56 and the side end face side of the upper housing 12 It is desirable to provide the inclined surface 56E.
Accordingly, when the engagement pin 45 and the second engagement portion 46 are not properly engaged, the second accommodation portion 56 that accommodates the second protrusion 52 of the engagement pin 45 is provided. It can come off from the 2nd accommodating part 56 along the inclined surface 56E. The angle of the inclined surface 56E is not limited.

図１４および図１５に示すように、傾斜面５６Ｅは、第２突出部５２の先端の半球部分５２Ａの始まり位置５２Ｂに対応する位置から始まるようにするのが望ましい。これにより、第２突出部５２の突っ込み量が不十分であれば、半球部分５２Ａがすぐに傾斜面５６Ｅにかかるので、第２突出部５２は第２収容部５６から外れることになる。 As shown in FIGS. 14 and 15, the inclined surface 56 E desirably starts from a position corresponding to the start position 52 B of the hemispherical portion 52 A at the tip of the second protrusion 52. As a result, if the amount of protrusion of the second protrusion 52 is insufficient, the hemispherical portion 52A is immediately applied to the inclined surface 56E, so that the second protrusion 52 is disengaged from the second accommodating portion 56.

第２係合手段１６は、携帯端末１０が閉じ状態および縦開き状態において、上筐体１２が第２回動軸３２を中心として回動しないように、連結部１３の連結部本体１３Ａに対する上筐体１２の回動を規制するための手段である。
この第２係合手段１６により、携帯端末１０が閉じ状態および縦開き状態において、使用者が意図せずに上筐体１２が第２回動軸３２を中心として回動せず、これにより上筐体１２、連結部１３、第２回動部材３４等における特定部位に負荷が集中して破損することを防止できるという効果が得られる。 The second engaging means 16 is configured so that the upper housing 12 does not rotate about the second rotation shaft 32 when the mobile terminal 10 is in the closed state and the vertically opened state. This is means for restricting the rotation of the housing 12.
The second engagement means 16 prevents the upper housing 12 from rotating about the second rotation shaft 32 unintentionally by the user when the mobile terminal 10 is in the closed state and the vertically open state. There is an effect that it is possible to prevent the load from being concentrated and damaged at specific parts of the housing 12, the connecting portion 13, the second rotating member 34, and the like.

図３〜図４に戻って、第２係合手段１６の構成を説明する。
第２係合手段１６は、連結部１３の連結部本体１３Ａに対して連結される上筐体１２の短辺側面１２Ｃに設けられた係合部６６と、連結部本体１３Ａにおいて短辺側面１２Ｂに対面する端面１３Ｂに設けられて係合部６６に係合される係合部６７とを備えている。
これらの係合部６６，６７は、第２回動部材３４が配置される位置に対して幅方向に沿った反対側に配置されている。 Returning to FIGS. 3 to 4, the configuration of the second engaging means 16 will be described.
The second engaging means 16 includes an engaging portion 66 provided on the short side surface 12C of the upper housing 12 connected to the connecting portion main body 13A of the connecting portion 13, and the short side surface 12B of the connecting portion main body 13A. And an engaging portion 67 that is provided on the end face 13B facing the engaging portion 66 and is engaged with the engaging portion 66.
These engaging portions 66 and 67 are arranged on the opposite side in the width direction with respect to the position where the second rotating member 34 is arranged.

係合部６６は、上筐体１２の短辺側面１２Ｂから連結部本体１３Ａの端面１３Ｂに向かって突没可能なロックピン６６Ａと、ロックピン６６Ａを連結部本体１３Ａの端面１３Ｂに向かって付勢するリターンスプリング６９と、リターンスプリング６９を圧縮させながらロックピン６６Ａを上筐体１２に収容させるためのロックボタン６６Ｃとを有する。ロックピン６６Ａは、リターンスプリング６９により上筐体１２の短辺側面１２Ｂから突出した状態に保持されている。 The engaging portion 66 includes a lock pin 66A that can project and retract from the short side surface 12B of the upper housing 12 toward the end surface 13B of the connecting portion main body 13A, and a lock pin 66A attached to the end surface 13B of the connecting portion main body 13A. A return spring 69 is provided, and a lock button 66C for accommodating the lock pin 66A in the upper housing 12 while compressing the return spring 69. The lock pin 66 A is held by the return spring 69 so as to protrude from the short side surface 12 B of the upper housing 12.

このような係合部６６は、上筐体１２の側部１２Ａに設けられたロックボタン６６Ｃを使用者が矢印Ａ−Ｂ方向（図３（Ｂ）参照、上筐体１２の長手方向）に沿ってスライドさせることによりロックピン６６Ａを上筐体１２に収容可能となっている。
係合部６７は、ロックピン６６Ａの先端を収容可能な係合孔とされている（図３（Ａ）、図４参照）。 Such an engaging portion 66 is such that the user presses the lock button 66C provided on the side portion 12A of the upper housing 12 in the direction of arrow AB (see FIG. 3B, the longitudinal direction of the upper housing 12). The lock pin 66A can be accommodated in the upper housing 12 by being slid along.
The engagement portion 67 is an engagement hole that can accommodate the tip of the lock pin 66A (see FIGS. 3A and 4).

以上のような第２係合手段１６は、ロックピン６６Ａの先端が係合部６７に係合している状態では、連結部１３の連結部本体１３Ａに対する上筐体１２の回動が規制される。
従って、携帯端末１０は、閉じ状態および縦開き状態において、使用者が意図せずに上筐体１２が第２回動軸３２を中心として回動せず、これにより上筐体１２、連結部１３、第２回動部材３４等における特定部位に負荷が集中して破損することはない。 In the second engaging means 16 as described above, the rotation of the upper housing 12 with respect to the connecting portion main body 13A of the connecting portion 13 is restricted in a state where the tip of the lock pin 66A is engaged with the engaging portion 67. The
Accordingly, in the closed state and the vertically open state, the mobile terminal 10 is not intended to be rotated by the user and the upper housing 12 does not rotate about the second rotation shaft 32, thereby the upper housing 12 and the connecting portion. 13. The load does not concentrate on a specific part of the second rotating member 34 or the like and is not damaged.

そして、使用者が携帯端末１０を閉じ状態から横開き状態とするときは、使用者がロックボタン６６Ｃを操作することにより係合部６６，６７の係合状態を解除した後、第２回動軸３２を中心として連結部１３の連結部本体１３Ａに対して上筐体１２を手動で回動させる。 Then, when the user changes the portable terminal 10 from the closed state to the laterally open state, the second rotation is performed after the user releases the engaged state of the engaging portions 66 and 67 by operating the lock button 66C. The upper housing 12 is manually rotated with respect to the connecting portion main body 13A of the connecting portion 13 around the shaft 32.

なお、使用者が携帯端末１０を横開き状態から閉じ状態とするときは、第２回動軸３２を中心として連結部１３の連結部本体１３Ａに対して上筐体１２を手動で回動させれば、先端が係合部６７に接触したロックピン６６Ａがリターンスプリング６９を圧縮させながら一時的に上筐体１２に収容された後、再びリターンスプリング６９の伸張に伴ってロックピン６６Ａが上筐体１２から突出して係合部６７に係合し、これにより連結部１３の連結部本体１３Ａに対する上筐体１２の回動が再び規制される。 When the user changes the portable terminal 10 from the laterally open state to the closed state, the upper casing 12 is manually rotated with respect to the connecting portion main body 13A of the connecting portion 13 around the second rotating shaft 32. Then, after the lock pin 66A, whose tip is in contact with the engaging portion 67, is temporarily accommodated in the upper housing 12 while compressing the return spring 69, the lock pin 66A is again lifted along with the extension of the return spring 69. It protrudes from the housing 12 and engages with the engaging portion 67, whereby the rotation of the upper housing 12 with respect to the connecting portion main body 13A of the connecting portion 13 is restricted again.

次に、本実施形態の携帯端末１０の動作を説明する。
携帯端末１０が閉じ状態にあるとき、すなわち下筐体１１および上筐体１２が互いに重なり合う状態にあるとき、第１係合手段１５の第１係合部である係合ピン４５の第１突出部５１の頂部および第２突出部５２と、第２係合部４６の第１収容部５５および第２収容部５６とが対面する。 Next, the operation of the mobile terminal 10 of this embodiment will be described.
When the portable terminal 10 is in a closed state, that is, when the lower housing 11 and the upper housing 12 are in a state of overlapping each other, the first protrusion of the engagement pin 45 that is the first engagement portion of the first engagement means 15 The top part of the part 51 and the second projecting part 52 face each other, and the first housing part 55 and the second housing part 56 of the second engaging part 46 face each other.

この際、係合ピン４５に対する上筐体磁石６３の磁力の影響が下筐体磁石４８の磁力の影響よりも大きいため、上筐体磁石６３の磁力により係合ピン４５が下筐体１１の表面１１Ａから引き出されて確実に突出し、第１突出部５１の頂部および第２突出部５２が開口５８Ａ，５６Ｃから第１収容部５５および第２収容部５６に挿入される。
この際、リターンスプリング４７により第１収容部５５の開口５８Ａと第２収容部５６の開口５６Ｃとが上筐体１２の表面１２Ａに沿って連続しているため、第１収容部５５および第２収容部５６に対して第１突出部５１の頂部および第２突出部５２が円滑に挿入される。 At this time, since the influence of the magnetic force of the upper housing magnet 63 on the engaging pin 45 is larger than the influence of the magnetic force of the lower housing magnet 48, the engaging pin 45 of the lower housing 11 is caused by the magnetic force of the upper housing magnet 63. It is pulled out from the surface 11A and reliably protrudes, and the top of the first protrusion 51 and the second protrusion 52 are inserted into the first storage part 55 and the second storage part 56 from the openings 58A and 56C.
At this time, since the opening 58 A of the first housing portion 55 and the opening 56 C of the second housing portion 56 are continuous along the surface 12 A of the upper housing 12 by the return spring 47, The top portion of the first projecting portion 51 and the second projecting portion 52 are smoothly inserted into the housing portion 56.

図１２（Ａ）に示すように、携帯端末１０は、閉じ状態において、第１係合部である係合ピン４５が第２係合部４６の第１収容部５５および第２収容部５６に挿入されるが、第１収容部５５の開口５８Ａおよび第２収容部５６の開口５６Ｃはどちらも下筐体１１の表面１１Ａに対面しているため、係合ピン４５が第１収容部５５および第２収容部５６に対して挿脱自在であり、いわゆる第１係合手段１５がロックされない状態、換言すればロック解除状態となっている。
なお、図１２（Ａ）は携帯端末１０が閉じ状態における第１係合手段１５を示し、図１２（Ｂ）は携帯端末１０が横開き状態における第１係合手段１５を示す。 As shown in FIG. 12A, in the mobile terminal 10, in the closed state, the engagement pin 45 that is the first engagement portion is connected to the first accommodation portion 55 and the second accommodation portion 56 of the second engagement portion 46. Although inserted, both the opening 58A of the first housing portion 55 and the opening 56C of the second housing portion 56 face the surface 11A of the lower housing 11, so that the engagement pin 45 is connected to the first housing portion 55 and It is detachable with respect to the second accommodating portion 56, and the so-called first engaging means 15 is not locked, in other words, it is in the unlocked state.
12A shows the first engagement means 15 when the mobile terminal 10 is in the closed state, and FIG. 12B shows the first engagement means 15 when the mobile terminal 10 is in the laterally open state.

図９に示すように、上筐体磁石６３は、第１収容部５５における係合ピン４５の突出軸線６５の側部の極めて近傍にインサート成型により配置されているため、必要最低限の磁力を有していればよく、上筐体１２内の電子部品に影響を及ぼす虞れがある強力な磁石を用いることなく係合ピン４５を下筐体１１から確実に突出させることができる。
また、上筐体磁石６３が第１収容部５５にインサート成型されているため、上筐体磁石６３を別途個別に配置する（組み付ける）必要がない。 As shown in FIG. 9, the upper housing magnet 63 is disposed by insert molding in the very vicinity of the side of the protruding axis 65 of the engaging pin 45 in the first accommodating portion 55, so that the minimum necessary magnetic force is generated. The engaging pin 45 can be reliably protruded from the lower housing 11 without using a strong magnet that may affect the electronic components in the upper housing 12.
Further, since the upper casing magnet 63 is insert-molded in the first housing portion 55, it is not necessary to separately arrange (assemble) the upper casing magnet 63 separately.

次に、携帯端末１０が閉じ状態から縦開き状態に移行するとき、すなわち下筐体１１に対して上筐体１２が第１回動軸３１を中心として回動を開始し、下筐体１１の表面１１Ａと上筐体１２の表面１２Ａとが離反する開いた状態と閉じた状態との間の遷移状態においては、第１収容部５５および第２収容部５６から第１突出部５１の頂部および第２突出部５２が抜け出し始める。
この際、リターンスプリング４７により第１収容部５５の開口５８Ａと第２収容部５６の開口とが上筐体１２の表面１２Ａに沿って連続しているため、第１収容部５５および第２収容部５６から第１突出部５１の頂部および第２突出部５２が円滑に抜け出し、第２収容部５６から外れ始める。 Next, when the portable terminal 10 shifts from the closed state to the vertically opened state, that is, the upper housing 12 starts to rotate around the first rotation shaft 31 with respect to the lower housing 11, and the lower housing 11 In the transition state between the open state and the closed state in which the surface 11A of the upper housing 12 and the surface 12A of the upper housing 12 are separated from each other, the top of the first protrusion 51 from the first storage 55 and the second storage 56 And the 2nd protrusion part 52 begins to come out.
At this time, since the opening 58A of the first housing portion 55 and the opening of the second housing portion 56 are continuous along the surface 12A of the upper housing 12 by the return spring 47, the first housing portion 55 and the second housing portion are accommodated. The tops of the first protrusions 51 and the second protrusions 52 smoothly come out of the part 56 and begin to be detached from the second storage part 56.

そして、下筐体１１の表面１１Ａと上筐体１２の表面１２Ａとが離反するに従って、係合ピン４５に対する上筐体磁石６３の磁力の影響が減少し、相対的に係合ピン４５に対する下筐体磁石４８の磁力の影響が上筐体磁石６３の磁力の影響を上回ると、保持部４９の上面４９Ａに第２突出部５２が接触するまで下筐体磁石４８の磁力により係合ピン４５が下筐体１１内に引き寄せられ、これにより第１突出部５１の頂部および第２突出部５２が下筐体１１の表面１１Ａから突出しないように係合ピン４５が下筐体１１内に収納される。 Then, as the surface 11A of the lower housing 11 and the surface 12A of the upper housing 12 are separated from each other, the influence of the magnetic force of the upper housing magnet 63 on the engaging pin 45 decreases, and the lower surface relative to the engaging pin 45 is relatively lowered. When the influence of the magnetic force of the housing magnet 48 exceeds the influence of the magnetic force of the upper housing magnet 63, the engagement pin 45 is applied by the magnetic force of the lower housing magnet 48 until the second protrusion 52 comes into contact with the upper surface 49 A of the holding portion 49. Is pulled into the lower housing 11, whereby the engaging pin 45 is accommodated in the lower housing 11 so that the top of the first protrusion 51 and the second protrusion 52 do not protrude from the surface 11 A of the lower housing 11. Is done.

このように、閉じ状態から縦開き状態に移行を開始してから完全な縦開き状態に至るまでの間、係合ピン４５が下筐体１１内に収納されるため、音声通話時に使用者の顔に係合ピン４５が干渉したり、あるいはメールの読み書きや送受信、Ｗｅｂ閲覧、各種設定時に操作部２３を操作する使用者の指が係合ピン４５に干渉して操作部２３の操作性が損なわれる虞れや、係合ピン４５を破損する虞れがない。
なお、係合ピン４５は、下筐体磁石４８とストッパ５０とが接触しないように下筐体１１内に収納されるため、例えば下筐体磁石４８とストッパ５０とが接触している状態に比較して、再び携帯端末１０が閉じ状態となったときに速やかに下筐体１１の表面から突出することができる。 Thus, since the engagement pin 45 is housed in the lower housing 11 from the start of the transition from the closed state to the vertical open state until the complete vertical open state, the user's voice call The engagement pin 45 interferes with the face, or the finger of the user who operates the operation unit 23 at the time of reading / writing / transmission / transmission of mail, Web browsing, various settings, etc. interferes with the engagement pin 45 and the operability of the operation unit 23 is reduced. There is no risk of damage or damage to the engagement pin 45.
Since the engagement pin 45 is housed in the lower housing 11 so that the lower housing magnet 48 and the stopper 50 do not contact with each other, for example, the lower housing magnet 48 and the stopper 50 are in contact with each other. In comparison, the portable terminal 10 can quickly protrude from the surface of the lower housing 11 when it is closed again.

続いて、携帯端末１０が閉じ状態から横開き状態に移行するとき、すなわち下筐体１１に対して上筐体１２が第２回動軸３２を中心として回動を開始し、下筐体１１の表面１１Ａと上筐体１２の表面１２Ａとが離反すると、上筐体１２に追従して第２収容部５６が第２突出部５２を巻き込むように回動するものの、開口５８Ａの縁部が第１突出部５１の側面に接触することにより第１収容部５５の回転が規制され、リターンスプリング４７を巻き方向に圧縮させながら上筐体１２に対して相対的に回動して、下筐体１１の表面１１Ａに対して開口５８Ａを対面させた状態を維持する。
図１１は、携帯端末１０が閉じ状態から下筐体１１に対して上筐体１２が第２回動軸３２を中心として所定角度回動したときの状態を示す斜視図である。 Subsequently, when the mobile terminal 10 shifts from the closed state to the laterally open state, that is, the upper housing 12 starts rotating around the second rotation shaft 32 with respect to the lower housing 11, and the lower housing 11 When the surface 11A of the upper housing 12 and the surface 12A of the upper housing 12 are separated from each other, the second housing portion 56 follows the upper housing 12 and rotates so as to wind up the second protrusion 52, but the edge of the opening 58A The rotation of the first accommodating portion 55 is restricted by contacting the side surface of the first projecting portion 51, and the return spring 47 is rotated relative to the upper housing 12 while being compressed in the winding direction. The state where the opening 58A faces the surface 11A of the body 11 is maintained.
FIG. 11 is a perspective view showing a state when the upper housing 12 is rotated by a predetermined angle about the second rotation shaft 32 with respect to the lower housing 11 from the closed state of the mobile terminal 10.

図１０（Ａ）に示すように、第２収容部５６は、開口５６Ｃ、５６Ｄに直交する内面６１が平滑な曲面となっている。内面６１は、開口５６Ｃから最も遠い奥部６１Ａから開口５６Ｃに最も近い手前部６１Ｂに向かって曲率半径Ｒ１〜Ｒ５が連続的に大きくなる複数の曲面により形成されている。
すなわち、第２収容部５６は、開口５６Ｃ、５６Ｄに直交する内面６１の曲率半径が入口側から奥側に向かって連続的に小さくなっているため、上筐体１２に追従して回動するにあたって、係合ピン４５の第２突出部５２の周面を捕捉して、確実に肉抜部５６Ｂ内に保持できる。 As shown in FIG. 10A, in the second housing portion 56, the inner surface 61 orthogonal to the openings 56C and 56D is a smooth curved surface. The inner surface 61 is formed by a plurality of curved surfaces whose curvature radii R1 to R5 continuously increase from the innermost part 61A farthest from the opening 56C toward the front part 61B closest to the opening 56C.
That is, since the curvature radius of the inner surface 61 orthogonal to the openings 56C and 56D is continuously reduced from the entrance side to the back side, the second housing portion 56 rotates following the upper housing 12. In this case, the peripheral surface of the second projecting portion 52 of the engagement pin 45 can be captured and securely held in the lightening portion 56B.

具体的には、係合ピン４５の第２突出部５２を開口６１Ｂから第２収容部５６の開口部６１内に円滑に導き、いわゆる第２突出部５２を拾い上げ易くできる。
この段階では、第２突出部５２の周面が第２収容部５６に覆われるため、第１係合部である係合ピン４５が第２係合部４６から抜け出し不可能となり、第１係合手段１５により下筐体１１の長手方向端部と上筐体１２の長手方向端部同士が係合され、いわゆるロックされる状態となる。 Specifically, the second protrusion 52 of the engagement pin 45 can be smoothly guided from the opening 61B into the opening 61 of the second storage part 56, so that the so-called second protrusion 52 can be easily picked up.
At this stage, since the peripheral surface of the second protrusion 52 is covered with the second accommodating portion 56, the engagement pin 45, which is the first engagement portion, cannot be removed from the second engagement portion 46, and the first engagement The joining means 15 engages the longitudinal ends of the lower housing 11 and the longitudinal ends of the upper housing 12 so as to be in a so-called locked state.

なお、本実施形態においては、携帯端末１０が閉じ状態から下筐体１１に対して第２回動軸３２を中心として上筐体１２を回動させ、下筐体１１の表面１１Ａと上筐体１２の表面１２Ａとの間の挟み角度が約３０度以上になると第２突出部５２が第２収容部５６から抜き出し不可能となり、第１係合手段１５によりロックされる状態となる。 In the present embodiment, the upper casing 12 is rotated around the second rotation axis 32 with respect to the lower casing 11 from the closed state of the mobile terminal 10, and the surface 11 A of the lower casing 11 and the upper casing 11 are rotated. When the sandwiching angle with the surface 12A of the body 12 is about 30 degrees or more, the second projecting portion 52 cannot be extracted from the second accommodating portion 56 and is locked by the first engaging means 15.

そして、第２収容部５６の内面６１の曲率半径が入口側から奥側に向かって連続的に小さくなっているため、保持部４９にストッパ５０が接触するまで下筐体１１から係合ピン４５が引き出され、携帯端末１０が完全な横開き状態となると、係合ピン４５の第２突出部５２の軸線が第２回動軸３２に沿って配置される。 And since the curvature radius of the inner surface 61 of the 2nd accommodating part 56 is continuously small toward the back | inner side from the entrance side, it is the engagement pin 45 from the lower housing | casing 11 until the stopper 50 contacts the holding | maintenance part 49. Is pulled out and the mobile terminal 10 is in a completely laterally open state, the axis of the second protrusion 52 of the engagement pin 45 is arranged along the second rotation shaft 32.

以上のような実施形態の携帯端末１０によれば、閉じ状態において上筐体磁石６３の磁力により第１係合部である係合ピン４５が下筐体１１から突出して第２係合部４６の第１収容部５５および第２収容部５６に挿入されるがロックされず、縦開き状態において下筐体磁石６４の磁力により係合ピン４５が下筐体１１に収容され、横開き状態において上筐体１２に追従する第２収容部５６によりロック状態となるため、上筐体１２を片持ち支持する第２回動部材３４を第１係合手段１５が補助することになる。
従って、この携帯端末１０によれば、閉じ状態と横開き状態との間の状態や、完全な横開き状態において、落下や衝撃等による外力が加わっても上筐体１２、連結部１３、第２回動部材３４等における特定部位に負荷が集中せず、破損の虞れが少ない。 According to the mobile terminal 10 of the embodiment as described above, the engaging pin 45 as the first engaging portion protrudes from the lower housing 11 by the magnetic force of the upper housing magnet 63 in the closed state, and the second engaging portion 46. Are inserted into the first housing portion 55 and the second housing portion 56 but are not locked, and the engaging pin 45 is housed in the lower housing 11 by the magnetic force of the lower housing magnet 64 in the vertically opened state, and in the horizontally opened state. Since the second housing portion 56 that follows the upper housing 12 is locked, the first engaging means 15 assists the second rotating member 34 that cantilever-supports the upper housing 12.
Therefore, according to the mobile terminal 10, even when an external force is applied due to a drop or an impact in a state between the closed state and the laterally opened state or in a completely laterally opened state, the upper housing 12, the connecting portion 13, The load is not concentrated on a specific part of the two-rotating member 34 or the like, and there is little possibility of breakage.

なお、前述した実施形態では、第１収容部５５の内面５８が平滑面とされた第１係合手段１５を例示したが、図１６に示す第１係合手段１５Ａも本発明に含まれる。
図１６に示す第１係合手段１５Ａは、第１収容部５５Ａの内面５８Ｃに突部５８Ｄが設けられている。一方、第１収容部５５Ａに挿入される係合ピン４５Ａの第１突出部５１Ａの側面に凹部５１Ｂが設けられている。 In the above-described embodiment, the first engagement means 15 in which the inner surface 58 of the first accommodating portion 55 is a smooth surface is exemplified, but the first engagement means 15A shown in FIG. 16 is also included in the present invention.
In the first engagement means 15A shown in FIG. 16, a protrusion 58D is provided on the inner surface 58C of the first accommodating portion 55A. On the other hand, a recess 51B is provided on the side surface of the first protrusion 51A of the engagement pin 45A inserted into the first housing 55A.

このような第１係合手段１５Ａは、携帯端末１０が閉じ状態から横開き状態とするとき、すなわち下筐体１１に対して上筐体１２が第２回動軸３２を中心として回動し始めたが下筐体１１の表面１１Ａと上筐体１２の表面１２Ａとの間の挟み角度が約３０度未満（低角度（鈍角））でロック状態に至らない場合においても、第１収容部５５Ａの突部５８Ｄと係合ピン４５Ａの凹部５１Ｂとが係合するため、携帯端末に衝撃等による外力が加わっても、係合ピン４５Ａが第２収容部５５Ａから抜け落ちることを防止することができる。 Such first engaging means 15A is configured such that when the portable terminal 10 is changed from the closed state to the laterally opened state, that is, the upper housing 12 rotates about the second rotation shaft 32 with respect to the lower housing 11. The first housing portion is started even when the angle between the surface 11A of the lower housing 11 and the surface 12A of the upper housing 12 is less than about 30 degrees (low angle (obtuse angle)) and the locked state is not reached. Since the protrusion 58D of 55A and the recess 51B of the engagement pin 45A are engaged, it is possible to prevent the engagement pin 45A from falling out of the second accommodating portion 55A even when an external force due to impact or the like is applied to the mobile terminal. it can.

また、前述した実施形態では、上筐体１２に対して第１収容部５５が回動し、第２収容部５６が上筐体１２に固定されていたが、本発明はこれに限定されることなく、係合ピン４５の形状によっては、上筐体１２の表面１２Ａに開口があればよい。
例えば、開口の一部が上筐体１２の側面部までつながっている構成をとって、横開き状態において係合ピン４５の一部が開口部にひっかかるよう構成してもよい。 In the above-described embodiment, the first housing portion 55 is rotated with respect to the upper housing 12 and the second housing portion 56 is fixed to the upper housing 12. However, the present invention is limited to this. Instead, depending on the shape of the engagement pin 45, the surface 12A of the upper housing 12 may have an opening.
For example, a configuration in which a part of the opening is connected to the side surface of the upper housing 12 may be configured such that a part of the engagement pin 45 is caught in the opening in the laterally open state.

また、前述した実施形態では、係合ピン４５を第１突出部５１および第２突出部５２で略Ｌ型に形成した例について説明したが、これに限らないで、係合ピンの先端を例えばＴ字状、ボール形状や係合ピン４５とは逆向きのＬ型に形成することも可能である。 In the above-described embodiment, the example in which the engagement pin 45 is formed in the substantially L shape by the first protrusion 51 and the second protrusion 52 has been described. It is also possible to form an L shape opposite to the T shape, the ball shape, or the engagement pin 45.

次に、本発明の第２実施形態について説明する。
前述した第１実施形態においては、係合ピン４５を構成する第１突出部５１と第２突出部５２とを一体的に形成したが、図１６に示すように、第１突出部５１と第２突出部５２を別体で構成することもできる。例えば第１突出部５１の上端面から上方に向けて回動軸５１Ｃを設け、一方、別体の第２突出部５２には、回動軸５１Ｃを挿嵌して第２突出部５２を回動可能に支持する軸穴５２Ｃを設ける。 Next, a second embodiment of the present invention will be described.
In the first embodiment described above, the first projecting portion 51 and the second projecting portion 52 constituting the engaging pin 45 are integrally formed. However, as shown in FIG. The two protrusions 52 can also be configured separately. For example, the rotation shaft 51C is provided upward from the upper end surface of the first protrusion 51. On the other hand, the rotation shaft 51C is inserted into the separate second protrusion 52 and the second protrusion 52 is rotated. A shaft hole 52C that is movably supported is provided.

これにより、第２突出部５２は回動可能となるので、前述した第１実施形態と同様の作用・効果を得ることができる。なお、第２突出部５２の回動角度を規制する場合には、回動軸５１Ｃを例えば矩形断面とし、軸穴５２Ｃの断面として回動軸５１Ｃが所定の角度回動可能な形状とすることができる。あるいは、回動軸５１Ｃおよび軸穴５２Ｃをともに円形断面とし、別途、第２突出部５２の回動範囲を規定するストッパを設けることもできる。 Thereby, since the 2nd protrusion part 52 becomes rotatable, the effect | action and effect similar to 1st Embodiment mentioned above can be acquired. When the rotation angle of the second protrusion 52 is restricted, the rotation shaft 51C has, for example, a rectangular cross section, and the rotation shaft 51C has a shape capable of rotating by a predetermined angle as a cross section of the shaft hole 52C. Can do. Alternatively, both the rotation shaft 51C and the shaft hole 52C may have a circular cross section, and a stopper that defines the rotation range of the second protrusion 52 may be provided separately.

本発明は、第２係合部の磁石が設けられた第２収容部が、磁性体で形成された係合ピンを磁力により引き付けて係合ピンを第１筐体の表面から突出させ、第２筐体を第２回動軸回りに回動させることにより、第２収容部に第２突出部を収容して係合ピンをロックする。また、第２突出部が第１突出部の軸線を中心として回動可能なので、係合ピンが十分に突出していない場合や、第２突出部が所定の位置にない場合等の不十分な係合状態では、第１筐体に対して第２筐体が相対的に移動するような外力が作用した際には、係合ピンは第２係合部から抜け出すので、係合ピンや第２筐体における第２係合部の周囲等の破損を防止することができるという効果を有し、第１筐体および第２筐体が連結部を介して連結され、閉じ状態から縦開き状態や横開き状態に開閉可能な携帯端末への適用に好適である。 According to the present invention, the second accommodating portion provided with the magnet of the second engaging portion attracts the engaging pin formed of a magnetic body by a magnetic force to cause the engaging pin to protrude from the surface of the first housing. By rotating the two housings around the second rotation axis, the second protrusion is accommodated in the second accommodating portion and the engaging pin is locked. In addition, since the second projecting portion can be rotated about the axis of the first projecting portion, the engagement is insufficient when the engagement pin does not project sufficiently or the second projecting portion is not in a predetermined position. In the combined state, when an external force that moves the second housing relative to the first housing is applied, the engagement pin comes out of the second engagement portion. It has the effect that the surroundings of the second engaging portion in the housing can be prevented from being damaged, and the first housing and the second housing are connected via the connecting portion, and from the closed state to the vertically opened state, It is suitable for application to a portable terminal that can be opened and closed in a horizontally open state.
