Description

本発明は、携帯端末に関し、特に使用時に筐体同士をスライドさせることができる携帯端末に関する。   The present invention relates to a mobile terminal, and more particularly to a mobile terminal that can slide between casings when in use.

現在、携帯電話やＰＤＡなどの携帯端末では、複数の筐体から構成され、筐体同士を互いにスライドさせる機構のものがある。スライド機構としては、例えば、互いにスライドする筐体同士の一方にガイド溝などを形成し、他方の筐体をガイド溝に沿って移動させる構成である。スライド機構を有する従来の携帯端末としては、例えば、下記特許文献に示すものがある。   Currently, portable terminals such as mobile phones and PDAs have a mechanism that is configured of a plurality of casings and that allows the casings to slide with respect to each other. As the slide mechanism, for example, a guide groove or the like is formed in one of the housings that slide with each other, and the other housing is moved along the guide groove. As a conventional portable terminal having a slide mechanism, for example, there are those shown in the following patent documents.

特開２００６−３３３０７９号公報JP 2006-333079 A 特開２００５−００３７９４号公報JP 2005-003794 A 特開２００７−２０１８０号公報JP 2007-20180 A 特開２００７−１３２５０８号公報JP 2007-132508 A

ところで、上記のようにスライド機構を備えた携帯端末は、使用時に操作部が形成された面に対して、表示部が形成された面が平行であると、使用する際に、操作部を操作しながら表示部を視認しにくく、使い勝手が悪かった。そこで、従来では、上記特許文献４に示すように、表示部を操作部側に傾斜（チルト）させる構成のものがある。
しかし、表示部が形成された筐体をスライドさせて操作部に対してチルトさせる機構は、スライドさせる機構とチルトさせる機構とが必要となるため構成が複雑となり、携帯端末の小型化を阻害する要因となっていた。また、チルトさせる領域を確保する必要上、スライドさせた状態において操作部の領域を広く確保することができないため、使用の際に操作しづらくなる点で改善の余地があった。 By the way, a portable terminal equipped with a slide mechanism as described above operates the operation unit when used if the surface on which the display unit is formed is parallel to the surface on which the operation unit is formed when used. However, it was difficult to see the display part and the usability was bad. Therefore, conventionally, as shown in Patent Document 4, there is a configuration in which the display unit is tilted (tilted) to the operation unit side.
However, the mechanism for sliding the casing on which the display unit is formed and tilting it with respect to the operation unit requires a sliding mechanism and a tilting mechanism, which complicates the configuration and hinders downsizing of the mobile terminal. It was a factor. In addition, since it is necessary to secure an area for tilting, it is not possible to secure a wide area for the operation unit in the slid state, so there is room for improvement in that it is difficult to operate the apparatus during use.

本発明は、上記事情に鑑みてなされたもので、その目的は、筐体同士をスライドさせる機構とチルトさせる機構とを備えた携帯端末において、操作部を広く確保することができ、使い勝手が良い携帯端末を提供することにある。   The present invention has been made in view of the above circumstances, and an object of the present invention is to ensure a wide operation section in a portable terminal including a mechanism for sliding the casings and a mechanism for tilting, and is easy to use.

Here, as shown in FIG. 6, “formed inside the first housing” means that the shaft 7 and the free stop hinge 6 are opposite to the surface on which the operation portion 5 of the second housing is formed. It is provided between and.

また、本発明にかかる携帯端末１において、第２のスライド部材３１は、第１筐体２と第２筐体３とのスライドを支持する機能とは別に、第１筐体２に対して第２筐体３をチルトさせるためのチルト部材として機能している。   Further, in the mobile terminal 1 according to the present invention, the second slide member 31 is different from the first housing 2 in function of supporting the sliding of the first housing 2 and the second housing 3. 2 Functions as a tilt member for tilting the housing 3.

次に、スライド手段の動作を説明する。
図７は、スライド前のスライド手段の状態を示す平面図である。図８は、スライド前の状態を示す携帯端末の断面図である。図９は、スライド後のスライド手段の状態を示す平面図である。図１０は、スライド後の状態を示す携帯端末の断面図である。ここでは、図７及び図９では、第１のスライド部材１１の表面を平面視した状態を示しており、スライド手段の構成を説明するため、第２筐体などは図には示さず、省略している。 Next, the operation of the sliding means will be described.
FIG. 7 is a plan view showing a state of the sliding means before sliding. FIG. 8 is a cross-sectional view of the mobile terminal showing a state before sliding. FIG. 9 is a plan view showing a state of the sliding means after sliding. FIG. 10 is a cross-sectional view of the mobile terminal showing a state after sliding. Here, FIG. 7 and FIG. 9 show the state of the surface of the first slide member 11 in plan view, and the second housing and the like are not shown in the drawings and are omitted for explaining the configuration of the slide means. is doing.

図７及び図８に示すように、スライドさせる前で、第１筐体２と第２筐体３とを重ね合わせている状態では、第２のスライド部材３１のガイドピース３６はそれぞれ、第１のスライド部材１１の短辺においてスライド方向側の端部に位置している。このとき、一対のガイド片２１ａ，２１ｂの回動端部２３ａ，２３ｂは、逃げ溝１２の、スライドさせる方向側の端部に位置している。   As shown in FIG. 7 and FIG. 8, the guide pieces 36 of the second slide member 31 are respectively in the state where the first housing 2 and the second housing 3 are overlapped before being slid. The slide member 11 is located at the end on the slide direction side on the short side. At this time, the rotation end portions 23a and 23b of the pair of guide pieces 21a and 21b are located at the end portions of the escape grooves 12 on the sliding direction side.

スライド時には、使用者が第１筐体２の操作部５が形成された側の面（図８において上面）に対して、第２筐体３全体を短辺の長さ方向に沿って押し進めることで、第２筐体３を第１筐体２に対してスライド移動させることができる。第２筐体３が第１筐体２に対してスライド移動すると同時に、第２筐体３に固定された第１のスライド部材１１が第２のスライド部材３１に対してスライド移動する。すると、第２のスライド部材３１のガイドピース３６が、第１のスライド部材１の短辺に沿って反対側の端部側へ相対的に変位する。   When sliding, the user pushes the entire second housing 3 along the length direction of the short side with respect to the surface (the upper surface in FIG. 8) of the first housing 2 on which the operation unit 5 is formed. Thus, the second housing 3 can be slid relative to the first housing 2. At the same time as the second housing 3 slides relative to the first housing 2, the first slide member 11 fixed to the second housing 3 slides relative to the second slide member 31. Then, the guide piece 36 of the second slide member 31 is relatively displaced toward the opposite end along the short side of the first slide member 1.

また、第１のスライド部材１１が第２のスライド部材３１に対してスライドするとともに、第２のスライド部材３１によって一対のガイド片２１ａ，２１ｂのガイド部が円弧上に回転移動する。そして、一対のガイド片２１ａ，２１ｂは、第１のスライド部材１１に固定された回動軸ｓ１，ｓ２を回動の中心としてそれぞれ反対向きに回動する。一対のガイド片２１ａ，２１ｂの軸支された側の端部が、互いに噛み合わされたギア部２２ａ，２２ｂによって連結されているため、一対のガイド片２１ａ，２１ｂとが同じ移動量で回動する。言い換えると、一対の逃げ溝１２に沿って移動するガイド部は、逃げ溝１２を互いに線対称な関係でとらえた場合に、逃げ溝１２に対して対称に等しい位置にある。このように、ガイド片２１ａ，２１ｂは、スライド時に、ガイド部が設けられた回動端部がそれぞれ、スライド方向に平行な線に対して互いに線対称となる軌跡に沿って移動する。   Further, the first slide member 11 slides with respect to the second slide member 31, and the second slide member 31 causes the guide portions of the pair of guide pieces 21a and 21b to rotate on an arc. The pair of guide pieces 21a and 21b rotate in opposite directions with the rotation axes s1 and s2 fixed to the first slide member 11 as the centers of rotation. Since the end portions of the pair of guide pieces 21a and 21b on which the shafts are supported are connected by the gear portions 22a and 22b engaged with each other, the pair of guide pieces 21a and 21b rotate with the same movement amount. . In other words, the guide portions that move along the pair of escape grooves 12 are in symmetrically equal positions with respect to the escape grooves 12 when the escape grooves 12 are viewed in a line-symmetric relationship. As described above, the guide pieces 21a and 21b move along the trajectory in which the rotation end portions provided with the guide portions are symmetrical with respect to a line parallel to the slide direction when sliding.

また、図４及ぶ図５に示すように第２のスライド部材３１には、ガイド溝３２が形成されているため、ガイド部が逃げ溝１２に沿って移動する際にガイド部のスライド方向に対して垂直方向への移動を許容することができる。   Further, as shown in FIGS. 4 and 5, since the guide groove 32 is formed in the second slide member 31, when the guide part moves along the escape groove 12, the guide part 32 moves with respect to the sliding direction of the guide part. Therefore, movement in the vertical direction can be allowed.

図９及び１０に示すように、第２筐体３を第１筐体１に対してスライド移動させる際には、第２のスライド部材３１のガイドピース３６が当該端部において第１のスライド部材１１を固定した第２筐体３の壁部と当接する位置まで移動させることができる。このとき、一対のガイド片２１ａ，２１ｂが、逃げ溝１２において、スライド前に位置した端部とは反対側の端部に位置する。   As shown in FIGS. 9 and 10, when the second housing 3 is slid with respect to the first housing 1, the guide piece 36 of the second slide member 31 is the first slide member at the end portion. 11 can be moved to a position where it comes into contact with the wall of the second housing 3 to which the 11 is fixed. At this time, the pair of guide pieces 21a and 21b are located at the end of the escape groove 12 opposite to the end located before the slide.

携帯端末１の使用者は、図７及び図８に示すように、第１筐体２と第２筐体３とを重ね合わせた状態、または、図９及び図１０に示すように、第１筐体２に対して第２筐体３をスライドさせた状態のいずれかで使用することが多い。そこで、本実施形態の携帯端末１は、それぞれの状態のときに、第１筐体２と第２筐体３との位置関係を保持するため、一対のガイド片２１ａ，２１ｂのガイド部をガイド溝に両端部に位置するときに付勢部材によって係止している。   As shown in FIGS. 7 and 8, the user of the portable terminal 1 is in a state in which the first housing 2 and the second housing 3 are overlapped, or as shown in FIGS. In many cases, the second casing 3 is slid with respect to the casing 2. Therefore, the portable terminal 1 of the present embodiment guides the guide portions of the pair of guide pieces 21a and 21b in order to maintain the positional relationship between the first housing 2 and the second housing 3 in each state. When it is located at both ends of the groove, it is locked by a biasing member.

図１１は、付勢部材の動作及び作用を説明する図である。付勢部材１４は、ガイド片２１ｂの挙動に合わせて湾曲した形状を有しており、ガイド片２１ｂの係止部２５が付勢部材１４の湾曲部に接触している状態では、付勢部材１４を構成する与圧バネの反発力を受ける。また、付勢部材１４の両方の端部は、ガイド片２１ｂの回動軸ｓ２を中心とする係止部２５の移動する円状の軌跡から離れる側に緩やかに湾曲している。このため、図１１（ａ）及び（ｃ）に示すように、ガイド片２１ｂが両端部に位置する状態から、図１１（ｂ）に示すスライド時のように回動状態へ移行する際には、付勢部材１４の端部を係止部２５に乗り越えさせて湾曲部側へ押しやる力を加える必要がある。このため、第１筐体２と第２筐体３とを重ね合わせた状態や第１筐体２と第２筐体３とをスライドさせた状態においては、ガイド片２１ｂが端部から離れる方向へ移動することを制限でき、第１のスライド部材１１と第２のスライド部材３１とが互いにスライド移動することを制限できる。こうして、携帯端末１の第１筐体２と第２筐体３とを重ね合わせた状態、及び、第１筐体２に対して第２筐体３をスライドさせた状態で携帯端末１の使用する場合に、第１筐体２及び第２筐体３が不測にスライド移動してしまうことを防止することができる。   FIG. 11 is a diagram illustrating the operation and action of the urging member. The urging member 14 has a curved shape in accordance with the behavior of the guide piece 21b, and the urging member is in a state where the locking portion 25 of the guide piece 21b is in contact with the curved portion of the urging member 14. 14 is subjected to the repulsive force of the pressurizing spring constituting 14. Further, both ends of the urging member 14 are gently curved toward the side away from the circular locus on which the locking portion 25 moves around the rotation axis s2 of the guide piece 21b. For this reason, as shown in FIGS. 11 (a) and 11 (c), when the guide piece 21b is shifted from the state where the guide pieces 21b are located at both ends, as shown in FIG. It is necessary to apply a force to push the end of the urging member 14 over the engaging portion 25 and push it toward the bending portion. For this reason, in the state where the first housing 2 and the second housing 3 are overlapped or the first housing 2 and the second housing 3 are slid, the direction in which the guide piece 21b is separated from the end portion. The first slide member 11 and the second slide member 31 can be restricted from sliding relative to each other. Thus, the portable terminal 1 is used in a state where the first casing 2 and the second casing 3 of the portable terminal 1 are overlapped and the second casing 3 is slid with respect to the first casing 2. In this case, it is possible to prevent the first housing 2 and the second housing 3 from sliding unexpectedly.

なお、付勢部材１４の構成は、上記のような形状のものに限定されず、逃げ溝１２の端部で一対のガイド片２１ａ，２１ｂのいずれかを係止することができれば、他の形状としてもよい。   The configuration of the urging member 14 is not limited to the shape as described above, and any other shape can be used as long as one of the pair of guide pieces 21a and 21b can be locked at the end of the escape groove 12. It is good.

次に、スライド手段及びチルト部材の動作を説明する。
図１２は、携帯端末のヒンジ部材の断面図である。なお、図１２は、ヒンジ回転軸の軸方向に垂直な断面で第１筐体及び第２筐体をみた状態を示している。
図１２（ａ）に示すように、第１筐体２及び第２筐体３が重ね合わされた状態では、第１筐体２の座部２ａにおける第２筐体２側の面に、チルト部材３１の支持板部３３が、スライド支持面３３ａを第２筐体２側へ向けた状態で、当接している。 Next, operations of the slide means and the tilt member will be described.
FIG. 12 is a cross-sectional view of the hinge member of the mobile terminal. FIG. 12 shows a state in which the first housing and the second housing are viewed in a cross section perpendicular to the axial direction of the hinge rotation shaft.
As shown in FIG. 12A, in a state where the first housing 2 and the second housing 3 are overlapped, a tilt member is formed on the surface of the seat 2a of the first housing 2 on the second housing 2 side. The support plate portion 33 of 31 is in contact with the slide support surface 33a facing the second housing 2 side.

ここで、第１筐体において、操作部５が形成された領域をＡ１とし、ヒンジ回転軸が形成された領域をＡ２とし、座部２ａが形成された領域をＡ３とする。すると、第１筐体をヒンジ回転軸の軸方向にみた状態で、第２筐体をスライドさせる方向から順に（つまり、図１２の左側から順に）、領域Ａ１、Ａ２、Ａ３が設けられている。   Here, in the first housing, an area where the operation unit 5 is formed is A1, an area where the hinge rotation shaft is formed is A2, and an area where the seat 2a is formed is A3. Then, in a state where the first housing is viewed in the axial direction of the hinge rotation axis, regions A1, A2, and A3 are provided in order from the direction in which the second housing is slid (that is, in order from the left side in FIG. 12). .

図１２（ａ）及び図１２（ｂ）に示すように、スライド時には、チルト部材３１の支持板部３３が窪み状の座部２ａに収容され、スライド支持面３３ａが、第１筐体２における領域Ａ１のスライド面と略同一平面上に位置するため、第２筐体３はスライド移動がチルド部材３３に妨げられることなく、図１２（ｂ）に示す、スライド方向端部まで移動させることができる。略同一平面上とは、スライド支持面３３ａとスライド面とが完全に同じ高さの面となる意味だけでなく、例えば僅かな段差や隙間がある状態でもスライドを妨げない範囲で同一平面上であればよいことを意味する。第２筐体３を座部２ａが形成された領域までスライドさせた状態でチルト部材３１の回動が可能になり、このとき、チルト部材３１のヒンジ部３４が設けられた領域Ａ２には、スライドさせた第２筐体３が存在していない状態となる。   As shown in FIGS. 12A and 12B, when sliding, the support plate portion 33 of the tilt member 31 is accommodated in the recessed seat portion 2 a, and the slide support surface 33 a is in the first housing 2. Since the second housing 3 is positioned on substantially the same plane as the slide surface of the area A1, the second housing 3 can be moved to the end in the slide direction shown in FIG. it can. The term “substantially on the same plane” not only means that the slide support surface 33a and the slide surface are completely the same height, but also, for example, on the same plane within a range that does not prevent the slide even when there are slight steps or gaps. It means that there should be. The tilt member 31 can be rotated in a state where the second housing 3 is slid to the region where the seat portion 2a is formed. At this time, in the region A2 where the hinge portion 34 of the tilt member 31 is provided, The slid second housing 3 does not exist.

すると、図１２（ｃ）に示すように、ヒンジ部３４のヒンジ回転軸６を中心として第１筐体２に対して第２筐体３を回動させて立ち上げるときに、領域Ａ２の上部の空間に立ち上げた第２筐体３の一部が進入し、操作部５が形成されている領域Ａ１側の上部に第２筐体３の大部分が位置してしまうことを回避することができる。こうすれば、チルト動作後において、操作部５を有する領域Ａ１には、第２筐体３の端部の一部しか進入しないため、領域Ａ１が狭くなることを防止できる。   Then, as shown in FIG. 12C, when the second housing 3 is turned up with respect to the first housing 2 around the hinge rotation shaft 6 of the hinge portion 34, the upper portion of the region A2 is raised. To avoid that a part of the second housing 3 that has been raised into the space enters and the most part of the second housing 3 is located at the upper part on the region A1 side where the operation unit 5 is formed. Can do. By so doing, only a part of the end of the second housing 3 enters the area A1 having the operation unit 5 after the tilting operation, so that the area A1 can be prevented from becoming narrow.

本発明の携帯端末は、互いにスライド可能な第１筐体２と第２筐体３とを備え、スライドさせた状態で、第２筐体３の表示部４の面をチルト部材３１によって第１筐体２の操作部５の面に対して傾斜させることができるチルト機構を有している。スライド時には、チルト部材３１におけるスライド支持面３３ａが形成された支持板部３３を、第１筐体２の座部２ａに当接させることで、スライドする第２筐体３に対してチルト部材３１が干渉することがないように、座部２ａへ退避させることができる。そして、第２筐体３を完全にスライドさせた状態で、チルト部材３１の支持板部３３を座部２ａから離間させて、立ち上げることで、第１筐体２に対して第２筐体３をチルト動作させることができる。このような構成によれば、チルト部材３１を第１筐体２に対してスライド方向の端部近傍に設けることで、第２筐体３を第１筐体２に対してスライドさせるための距離を確保することができることから、スライド後に第１筐体２の面に形成される操作部５の領域を広く確保することができる。このため、使用者は、操作部５を手指などで操作する際に、操作が行いやすく、使い勝手が良い。
なお、スライド手段は、一般的に用いられるスライドレール等であってもよい。 The portable terminal of the present invention includes a first casing 2 and a second casing 3 that are slidable with respect to each other, and the surface of the display unit 4 of the second casing 3 is first slid by a tilt member 31 while being slid. A tilt mechanism that can be tilted with respect to the surface of the operation unit 5 of the housing 2 is provided. At the time of sliding, the tilting member 31 is moved with respect to the sliding second housing 3 by bringing the support plate 33 formed with the slide support surface 33a of the tilting member 31 into contact with the seat 2a of the first housing 2. Can be retracted to the seat 2a so as not to interfere. Then, in a state where the second housing 3 is completely slid, the support plate portion 33 of the tilt member 31 is separated from the seat portion 2a and is raised, whereby the second housing 3 is raised with respect to the first housing 2. 3 can be tilted. According to such a configuration, the distance for sliding the second housing 3 relative to the first housing 2 by providing the tilt member 31 near the end in the sliding direction with respect to the first housing 2. Therefore, it is possible to secure a wide area of the operation unit 5 formed on the surface of the first housing 2 after the slide. For this reason, when a user operates the operation part 5 with a finger etc., operation is easy and it is convenient.
Note that the slide means may be a commonly used slide rail or the like.
