Description

本発明は、スライド式の携帯電話端末機や携帯情報端末機等のスライド式携帯端末機のスライド機構に関する。   The present invention relates to a sliding mechanism of a sliding mobile terminal such as a sliding mobile phone terminal or a portable information terminal.

従来、特許文献１〜３のように、上下方向に長い２つの筐体の裏面と表面を、スライド機構によって、上下方向にスライド自在に重合連結するスライド式携帯端末機は、前側にある第１筐体の表面に表示部を設け、後側にある第２筐体の表面に操作部を設け、第２筐体に対して第１筐体が、操作部を覆い隠す閉位置と出現する開位置にスライドして開閉する。   Conventionally, as in Patent Documents 1 to 3, a slide type portable terminal device in which the back and front surfaces of two casings that are long in the vertical direction are connected in a slidable manner in the vertical direction by a slide mechanism is the first on the front side. A display unit is provided on the surface of the housing, an operation unit is provided on the surface of the second housing on the rear side, and the first housing appears to be in a closed position that covers the operation unit with respect to the second housing. Slide to the position to open and close.

スライド機構は、所定の隙間を設けて対向配置する矩形板状の第１及び第２部材を、その左右側縁部で、上下方向にスライド自在に連結し、第１部材と第２部材の隙間に付勢部材を配置し、付勢部材の弾性付勢によって、第１部材と第２部材の間にスライド方向への付勢が生じるように構成する。第１部材と第２部材が、第１筐体の裏面と第２筐体の表面を、上下方向にスライド自在に重合連結し、付勢部材が、第２筐体に対して第１筐体が操作部を覆い隠す閉位置と出現する開位置にスライドするのを補助する。   The slide mechanism connects rectangular plate-like first and second members that are arranged to face each other with a predetermined gap so as to be slidable in the vertical direction at the left and right side edge portions, and the gap between the first member and the second member. The urging member is disposed in the urging member, and the urging in the sliding direction is generated between the first member and the second member by the elastic urging of the urging member. The first member and the second member overlap and connect the back surface of the first housing and the surface of the second housing so as to be slidable in the vertical direction, and the biasing member is connected to the second housing. Assists in sliding to the closed position where it covers the operating part and to the open position where it appears.

スライド機構の付勢部材として、１本の金属線材からなる線バネの一種である捩じりコイルバネを使用する特許文献１は、第１部材（第１筐体）が、スライド範囲内のどの位置にあっても、捩じりコイルバネの第１部材との連結部と第２部材との連結部の間の中央部に、第１の筐体と第２の筐体を電気的に接続するフレキシブル基板の配線スペースを確保する。それにより、フレキシブル基板の配線を容易にし、フレキシブル基板がスライド操作を妨げないようにしてスライド量を大きくする。しかし、近年、スライド式携帯端末機の薄形化が進むと共に、多機能化により、スライド機構の厚み方向の組み付けスペースが減少し、スライド機構には薄型化が強く求められている。捩じりコイルバネは、コイル部で線材が交差して厚みが大きくなる。付勢部材に捩じりコイルバネを使用するスライド機構は、全体の厚みが大きくなり、薄型化も行いにくいという問題がある。   Patent Document 1 that uses a torsion coil spring, which is a kind of wire spring made of a single metal wire, as the biasing member of the slide mechanism, describes which position within the slide range the first member (first housing) is. Even if it exists, the flexible which electrically connects a 1st housing | casing and a 2nd housing | casing to the center part between the connection part of the 1st member of a torsion coil spring, and the connection part of a 2nd member. Secure wiring space on the board. Thereby, the wiring of the flexible substrate is facilitated, and the sliding amount is increased so that the flexible substrate does not disturb the sliding operation. However, in recent years, the slide type mobile terminal has been made thinner, and the multifunctional function has reduced the assembly space in the thickness direction of the slide mechanism, and the slide mechanism is strongly required to be thin. The torsion coil spring is thickened by crossing wires at the coil portion. A slide mechanism that uses a torsion coil spring as a biasing member has a problem that the overall thickness is large and it is difficult to reduce the thickness.

スライド機構の付勢部材として、捩じりコイルバネの線材の厚みのみで構成可能なアクチュエータを使用する特許文献２は、スライド機構全体の厚みを薄く抑えることができる。しかし、アクチュエータでは、捩じりコイルバネのように中央部にスペースが確保できず、また、複数の部品から構成されるため、捩じりコイルバネと比べて、製造が容易でなく、コストも高くなるという問題がある。   Patent Document 2 that uses an actuator that can be configured only by the thickness of the wire of the torsion coil spring as the biasing member of the slide mechanism can reduce the thickness of the entire slide mechanism. However, in an actuator, a space cannot be secured in the central portion unlike a torsion coil spring, and since it is composed of a plurality of parts, it is not easy to manufacture and costs more than a torsion coil spring. There is a problem.

スライド機構の付勢部材として、１本の金属線材からなり、線材を交差させないように一平面上で曲げて、線材の厚みのみで構成した線バネを使用する特許文献３は、捩じりコイルバネと比べて、スライド機構全体の厚みを薄く抑えることができ、しかも、アクチュエータと比べて、製造が容易で、コストも安い。   Patent Document 3 is a torsion coil spring that uses a wire spring made up of only a thickness of a wire made of a single metal wire as a biasing member of a slide mechanism, bent on a plane so as not to cross the wires. In comparison with the actuator, the thickness of the entire slide mechanism can be reduced, and the manufacturing is easier and the cost is lower than the actuator.

特許文献３の線バネは、第１部材に連結する第１連結部と、第２部材に連結する第２連結部と、第１連結部と第２連結部を結ぶ直線に対してオフセットするように円弧形やＳ字形に形成し、第１連結部と第２連結部を繋ぐ第１バネ部と、第１連結部と第２連結部の一方、又は両方の周囲に渦巻き状に形成し、第１連結部と第２連結部の一方、又は両方と第１バネ部を繋ぐ第２バネ部を有し、第１バネ部は、第１部材（第１筐体）のスライド時に、第１連結部と第２連結部の間の直線距離が縮小するスライド工程で、第２バネ部の渦巻きを開く方向に、第２バネ部より突出するが、第１バネ部が圧縮変形するときに、第１バネ部の根元部が第２バネ部に巻き込まれ、第１バネ部の線材長さ（バネ長）が短くなり、それに伴い第１バネ部に生じる応力が大きくなるので、第１バネ部の耐久性が著しく低下するという問題がある。   The wire spring disclosed in Patent Document 3 is offset with respect to a first connecting portion connected to the first member, a second connecting portion connected to the second member, and a straight line connecting the first connecting portion and the second connecting portion. Formed in an arc shape or S-shape, spirally formed around one or both of the first spring portion and the first and second connection portions that connect the first connection portion and the second connection portion. , Having a second spring part that connects the first spring part to one or both of the first connection part and the second connection part, and the first spring part is the first spring when the first member (first housing) slides. When the linear distance between the first connecting portion and the second connecting portion is reduced, the second spring portion protrudes in the direction of opening the spiral of the second spring portion, but the first spring portion is compressed and deformed. The root portion of the first spring portion is wound around the second spring portion, and the wire length (spring length) of the first spring portion is shortened, resulting in the first spring portion. The force is increased, the durability of the first spring portion is lowered considerably.

A pair of swing arms 52 and 53 is used. The urging member 5 has a pin hole 54 serving as a connecting portion connected to the first member 2 at the free end of the first swing arm 52 and a pin hole 55 serving as a connecting portion connected to the second member 3. It is formed at the free end of the second swing arm 53. Engaging portions 56 and 57 of the wire spring 51 are formed at the portions near the swing end of the first swing arm 52 and the second swing arm 53, respectively. The wire spring 51 for engaging and fixing the connecting portions 51a and 51b formed at both ends of the engaging portion is offset with respect to the straight line connecting the first connecting portion 51a and the second connecting portion 51b, and the first connecting portion 51a and A first spring portion 51c that connects the second connecting portions 51b is formed in the central portion. Furthermore, the wire spring 51 is provided with two second spring portions 51d and 51e formed in a spiral shape around the first connecting portion 51a and the second connecting portion 51b, respectively.

Accordingly, the pair of swing arms 52 and 53 is configured to be elastically biased in the opening direction in which the free end side is separated.

このように、付勢部材５は、１本の金属線材からなる線バネ５１と一対の揺動アーム５２，５３で形成してあるので、容易に製造でき、コストも安い。本実施形態では、金属線材に断面円形のバネ用ステンレス鋼線を使用しているが、その他の公知のバネ用金属線材を使用してもよい。例えば、断面角形のバネ用金属線材やぜんまいバネ（渦巻きバネ）の素材になる幅狭で幅一定な長い板状の金属線材等を使用してもよい。   Thus, since the urging member 5 is formed by the wire spring 51 made of one metal wire and the pair of swing arms 52 and 53, it can be easily manufactured and the cost is low. In this embodiment, the stainless steel wire for springs having a circular cross section is used as the metal wire, but other known metal wires for springs may be used. For example, a metal plate for a spring having a square cross section, a long metal plate having a narrow width and a constant width, which is a material for a mainspring (spiral spring), or the like may be used.

また、線バネ５１は、第１連結部５１ａと第２連結部５１ｂを結ぶ直線に対してオフセットされた第１連結部５１ａと第２連結部５１ｂを繋ぐ第１バネ部５１ｃを有し、第１バネ部５１ｃによって、線バネ５１の第１連結部５１ａと第２連結部５１ｂの間の中央部に、第１連結部５１ａと第２連結部５１ｂを結ぶ直線に垂直な方向に開いたスペース（空間）８を確保するようにしている。本実施形態では、付勢部材５の中央部にスペース８を確保するための第１バネ部５１ｃのオフセット形状として、円弧形状を示しているが、コ字形状やく字形状、その他の異形状であってもよい。   The wire spring 51 includes a first spring portion 51c that connects the first connecting portion 51a and the second connecting portion 51b that are offset with respect to a straight line that connects the first connecting portion 51a and the second connecting portion 51b. A space opened by the first spring portion 51c in the direction perpendicular to the straight line connecting the first connection portion 51a and the second connection portion 51b at the center between the first connection portion 51a and the second connection portion 51b of the wire spring 51. (Space) 8 is secured. In the present embodiment, the arc shape is shown as the offset shape of the first spring portion 51c for securing the space 8 in the central portion of the urging member 5, but the U shape, the square shape, and other irregular shapes are used. There may be.

第１バネ部５１ｃは、第１連結部５１ａと第２連結部５１ｂを結ぶ直線距離が縮小するとき、円弧の曲率を大きくするように圧縮変形（弾性変形）し、第１連結部５１ａと第２連結部５１ｂを結ぶ直線距離を拡大する方向の弾性エネルギーを蓄える。   When the linear distance connecting the first connecting portion 51a and the second connecting portion 51b is reduced, the first spring portion 51c is compressively deformed (elastically deformed) to increase the curvature of the arc, and the first spring portion 51c and the first connecting portion 51a The elastic energy of the direction which expands the linear distance which connects 2 connection part 51b is stored.

第２バネ部５１ｄ，５１ｅは、巻き始め端部をそれぞれ第１揺動アーム５２と第２揺動アーム５３に形成した線バネ５１の係着部５４，５５固定してあり、揺動アーム５２，５３の挟み角度が狭くなって、第１連結部５１ａと第２連結部５１ｂを結ぶ直線距離が縮小すると、渦巻きを巻き込むように弾性変形し、巻き込まれた渦巻きを元に戻すような弾性エネルギーを蓄える。   The second spring portions 51 d and 51 e are fixed to the engaging portions 54 and 55 of the wire spring 51 formed at the first swing arm 52 and the second swing arm 53, respectively. , 53 becomes narrower, and when the linear distance connecting the first connecting portion 51a and the second connecting portion 51b is reduced, elastic energy is generated so that the spiral is elastically deformed and the entrained spiral is restored. Store.

このような第１バネ部５１ｃと第２バネ部５１ｄ，５１ｅは、同一平面上に配置する。また、第１連結部５１ａと第２連結部５１ｂは、それぞれ、その周囲にある第２バネ部５１ｄ，５１ｅの巻き始め側の端部を、係着部(バネ受け部)５６，５７に嵌め込み係合で切るように直線状に折り曲げ形成してある。これにより、線バネ５１に金属線材が交差する部分をなくし、線バネ５１の全体を金属線材の厚み（直径）のみで構成し、厚みを小さくするようにしてある。   The first spring portion 51c and the second spring portions 51d and 51e are arranged on the same plane. In addition, the first connecting portion 51a and the second connecting portion 51b are fitted into the engaging portions (spring receiving portions) 56 and 57, respectively, at the winding start end portions of the second spring portions 51d and 51e around the first connecting portion 51a and the second connecting portion 51b. It is bent and formed so as to be cut by engagement. As a result, the portion where the metal wire intersects the wire spring 51 is eliminated, and the entire wire spring 51 is constituted only by the thickness (diameter) of the metal wire, thereby reducing the thickness.

円弧形状（オフセット形状）を有する第１バネ部５１ｃは、第１連結部５１ａと第２連結部５１ｂとの間の直線距離が縮小するとき、第２バネ部５１ｄ，５１ｅの巻き込み量を大きくするように、第２バネ部５１ｄ，５１ｅの巻き込み方向に連続して形成してある。それにより、第１バネ部５１ｃが圧縮変形するときに、第１バネ部５１ｃが第２バネ部５１ｄ，５１ｅの巻き込み量を多くする状態に巻き込み、第１バネ部５１ｃの線材長さ（バネ長）を短くし、第１バネ部５１ｃでの弾発力を蓄積する。   The first spring portion 51c having an arc shape (offset shape) increases the amount of winding of the second spring portions 51d and 51e when the linear distance between the first connection portion 51a and the second connection portion 51b is reduced. As described above, the second spring portions 51d and 51e are continuously formed in the winding direction. Accordingly, when the first spring portion 51c is compressed and deformed, the first spring portion 51c is wound in a state where the amount of the second spring portions 51d and 51e is increased, and the wire length (spring length) of the first spring portion 51c is increased. ) And the elastic force at the first spring portion 51c is accumulated.

そして、図４ないし図６に戻って、一対のガイドレール４ａ，４ｂは、第２部材３の左右ガイド部３ａ，３ｂの内側に挿入され、接着剤等によって固定される（圧入固定や係止による固定でも可）。第１部材２の左右係合部２ａ，２ｂは、第２部材３の内側に固定された左右ガイドレール４ａ，４ｂに摺動自在に挿入される。それにより、第１部材２と第２部材３は、その左右側縁部で、上下方向にスライド自在に連結されて、所定の間隔を設けて対向配置される。   4 to 6, the pair of guide rails 4a and 4b are inserted inside the left and right guide portions 3a and 3b of the second member 3, and are fixed by an adhesive or the like (press-fit fixing or locking).

Then, the end portion of the first connecting portion 51 a is fitted into the engaging portion 56 formed on the first swing arm 52, and the end portion of the first connecting portion 51 a swings integrally with the first swing arm 52. To fix. Further, the end of the second connecting portion 51 b is fitted into the engaging portion 57 formed on the second swing arm 53, and the end of the second connecting portion 51 b swings integrally with the second swing arm 53. To fix. As a result, the first member 2 and the second member 3 are connected by the biasing member 5, and in the sliding direction (vertical direction) between the first member 2 and the second member 3 by the elastic biasing of the biasing member 5. It is comprised so that energizing of may arise.

第１揺動アーム５２を第１部材２に固定すると共に、第２揺動アーム５３を第２部材３に固定する際は、第１揺動アーム５２と第１部材２の間、及び第２揺動アーム５３と第２部材３の間に、それぞれ、樹脂ワッシャー７ａ，７ｂを１枚ずつ挟み込んでおく。それにより、第１揺動アーム５２と第１部材２の擦れによる磨耗、及び第２揺動フーム５３と第２部材３の擦れによる磨耗を、樹脂ワッシャー７ａ，７ｂによって防止し、磨耗による付勢部材５のガタツキや動作不良、寿命の低下等を防止するようにしてある。   When the first swing arm 52 is fixed to the first member 2 and the second swing arm 53 is fixed to the second member 3, the first swing arm 52 and the first member 2 and the second The resin washers 7a and 7b are sandwiched one by one between the swing arm 53 and the second member 3, respectively.

こうしてスライド機構１は、第１部材２と第２部材３によって、第１筐体２の裏面と第２筐体３の表面を上下方向にスライド自在に重合連結し、付勢部材５によって、第２筐体３に対して第１筐体２が、操作部１６を覆い隠す閉位置と出現する開位置にスライドするのを補助するように構成する。   In this way, the slide mechanism 1 has the first member 2 and the second member 3 overlap and connect the back surface of the first housing 2 and the front surface of the second housing 3 slidably in the vertical direction. The first housing 2 is configured to assist the sliding of the first housing 2 with respect to the two housings 3 to the closed position that covers the operation unit 16 and the open position where it appears.

ここで、付勢部材５は線バネ５１と、中間部を相対揺動可能に連結した一対の揺動アーム５２，５３とで形成してあることから、第１バネ部５１ｃの円弧形状（オフセット形状）が、上方向に突出する向きで、かつ一対の揺動アーム５２，５３の連結部分も第１バネ部５１ｃの突出方向と同方向に揺動した状態に、第１部材２と第２部材３の隙間に装着しており、第１バネ部５１ｃ及び両揺動アーム５２，５３によって、付勢部材５の中央部に確保したスペース８に、フレキシブル基板１８の中間部の上部を、第１部材２と第２部材３の隙間を通して、下方より挿入し、フレキシブル基板１８の中間部の上端、すなわち折り返し部１８ｃを第１バネ部５１ｃの下側に接近して配置する。それにより、フレキシブル基板１８の配線を容易にし、フレキシブル基板１８がスライド操作を妨げないようにしてスライド量を大きくするようにしてある。   Here, since the biasing member 5 is formed by a wire spring 51 and a pair of swing arms 52 and 53 whose intermediate portions are connected so as to be relatively swingable, an arc shape (offset) of the first spring portion 51c is provided. The shape of the first member 2 and the second member 2 is such that the connecting portion of the pair of swinging arms 52 and 53 swings in the same direction as the protruding direction of the first spring portion 51c. The upper portion of the intermediate portion of the flexible substrate 18 is attached to the space 8 secured in the central portion of the biasing member 5 by the first spring portion 51c and the swinging arms 52 and 53 by the first spring portion 51c and the swinging arms 52 and 53. The first member 2 and the second member 3 are inserted from below through the gap between them, and the upper end of the intermediate portion of the flexible substrate 18, that is, the folded portion 18c is arranged close to the lower side of the first spring portion 51c. Thereby, the wiring of the flexible board 18 is facilitated, and the sliding amount is increased so that the flexible board 18 does not disturb the sliding operation.

次に、スライド機構１の作用（スライド式携帯電話機１１のスライド操作）について説明する。   Next, the action of the slide mechanism 1 (slide operation of the slide type mobile phone 11) will be described.

まず、図９，図１０に示すように、スライド式携帯電話機１１を使用していない携帯時には、第２筐体１３に対して第１筐体１２がピッタリ重合し、第１筐体１２が第２筐体１３の操作部１６及び送話部１７を覆い隠す閉位置にある。この際、スライド機構１は、第２部材３に対して第１部材２の上部が対向し、第２部材３に固定した固定ピン６ｂよりも第１部材２に固定した固定ピン６ａが下方に位置し、付勢部材５の第２連結部５１ｂ及びその周囲にある第２バネ部５１ｅよりも第１連結部５１ａ及びその周囲にある第２バネ部５１ｄが下方に位置する。第１連結部５１ａと第２連結部５１ｂがそのような位置関係にある付勢部材５は、第１連結部５１ａと第２連結部５１ｂとの間の直線距離を拡大しようとする第１バネ部５１ｃによる付勢力よって、第２部材３に対して第１部材２を下方向へ付勢し、第１筐体１２をその下方向へのスライド終端位置である閉位置に保持する。また、第１バネ部５１ｃによって付勢部材５の中央部に確保したスペース８には、フレキシブル基板１８の中間部の上部が下方より挿入され、第１バネ部５１ｃの下側にフレキシブル基板１８の折り返し部１８ｃが接近して位置する。   First, as illustrated in FIGS. 9 and 10, when the mobile phone 11 is not being used, the first housing 12 is perfectly overlapped with the second housing 13, and the first housing 12 is 2 Closed position that covers the operation unit 16 and the transmission unit 17 of the housing 13. At this time, in the slide mechanism 1, the upper part of the first member 2 faces the second member 3, and the fixed pin 6 a fixed to the first member 2 is lower than the fixed pin 6 b fixed to the second member 3. The first connecting part 51a and the second spring part 51d therearound are positioned below the second connecting part 51b of the biasing member 5 and the second spring part 51e around it. The biasing member 5 in which the first connecting portion 51a and the second connecting portion 51b are in such a positional relationship is a first spring that attempts to increase the linear distance between the first connecting portion 51a and the second connecting portion 51b. The first member 2 is urged downward with respect to the second member 3 by the urging force of the portion 51c, and the first housing 12 is held in the closed position which is the slide end position in the downward direction. Further, the upper portion of the intermediate portion of the flexible substrate 18 is inserted from below into the space 8 secured in the central portion of the biasing member 5 by the first spring portion 51c, and the flexible substrate 18 is located below the first spring portion 51c. The folded portion 18c is located close to it.

続いて、スライド式携帯電話機１１を使用するに当たり、閉位置にある第１筐体１２を上方向へスライドさせると、スライド機構１は、第１部材２が第２部材３のガイド部材４ａ，４ｂをガイドとして上方向へスライドする。この際、第２部材３に固定した固定ピン６ｂは静止しているのに対し、第１部材２に固定した固定ピン６ａは上方向へ移動し、付勢部材５は全体的に固定ピン６ｂを中心に回動変位しながら、第１連結部５１ａと第２連結部５１ｂとの直線距離を漸次縮小する。このように第１連結部５１ａと第２連結部５１ｂとの直線距離が縮小するスライド工程において付勢部材５は、第１バネ部５１ｃが、その曲率を大きくするように変形し、第１連結部５１ａと第２連結部５１ｂを結ぶ直線距離を拡大する方向の弾性エネルギーを蓄える。この際、第１バネ部５１ｃは、第１連結部５１ａと第２連結部５１ｂの周囲にある２つの第２バネ部５１ｄ，５１ｅの巻き終わり部に対して第２バネ部５１ｄ，５１ｅの渦巻きを巻き込む方向に荷重を掛ける。それにより、第２バネ部５１ｄ，５１ｅの渦巻きは、第１バネ部５１ｃを巻き込む状態となり、巻き込まれた、第１バネ部５１ｃを元に戻すような弾性エネルギーを蓄える。   Subsequently, when using the slide type mobile phone 11, when the first housing 12 in the closed position is slid upward, the slide mechanism 1 is configured such that the first member 2 is the guide member 4 a, 4 b of the second member 3. Slide upward as a guide. At this time, while the fixing pin 6b fixed to the second member 3 is stationary, the fixing pin 6a fixed to the first member 2 moves upward, and the biasing member 5 is entirely fixed to the fixing pin 6b. , The linear distance between the first connecting portion 51a and the second connecting portion 51b is gradually reduced. In this way, in the sliding process in which the linear distance between the first connecting portion 51a and the second connecting portion 51b is reduced, the biasing member 5 is deformed so that the curvature of the first spring portion 51c is increased. The elastic energy in the direction of expanding the linear distance connecting the part 51a and the second connecting part 51b is stored. At this time, the first spring portion 51c is swirled by the second spring portions 51d and 51e with respect to the winding end portions of the two second spring portions 51d and 51e around the first connecting portion 51a and the second connecting portion 51b. Apply a load in the direction of winding. Thereby, the spirals of the second spring portions 51d and 51e are in a state where the first spring portion 51c is wound, and the elastic energy that returns the wound first spring portion 51c is stored.

続いて、図７、図８に示すように、さらに第１筐体１２を上方向へスライドさせると、第２筐体１３の操作部１６及び送話部１７が徐々に出現し、第１筐体１２は、そのスライド中間位置に到達する。この際、スライド機構１は、第１部材２が第２部材３のガイド部材４ａ，４ｂをガイドとしてさらに上方向へスライドし、第２部材３に対して第１部材２の上下中間部が対向し、第１部材２に固定した固定ピン６ａが第２部材３に固定した固定ピン６ｂと同じ高さ位置（上下位置）に移動し、第１連結部５１ａと第２連結部５１ｂを結ぶ直線が第１部材２のスライド方向に対して垂直になり、第１連結部５１ａと第２連結部５１ｂとの直線距離が最小になる。このように第１連結部５１ａと第２連結部５１ｂが同じ高さ位置に並び、第１連結部５１ａと第２連結部５１ｂとの直線距離が最小になるスライド中間位置において付勢部材５は、第１バネ部５１ｃが最大に圧縮変形し、最大の弾性エネルギーを蓄える。この際、第１バネ部５１ｃは、第１連結部５１ａと第２連結部５１ｂの周囲にある２つの第２バネ部５１ｄ，５１ｅの巻き終わり部に対して第２バネ部５１ｄ，５１ｅの渦巻きを巻き込む方向に最大の荷重を掛ける。それにより、第２バネ部５１ｄ，５１ｅの渦巻きは、第１バネ部５１ｃによって最大に巻き込まれ、最大の弾性エネルギーを蓄えると同時に、巻き終わり部からの線材を最大に繰り出し、第１バネ部５１ｃの線材長さ（バネ長）を最大に長くし、第１バネ部５１ｃに生じる応力を小さくする。また、この際、付勢部材５の付勢方向は、第１部材２（第１筐体１２）のスライド方向と垂直の方向となり、第１部材２は、上方向及び下方向、いずれの方向にもスライドしない。   Subsequently, as shown in FIGS. 7 and 8, when the first housing 12 is further slid upward, the operation unit 16 and the transmission unit 17 of the second housing 13 gradually appear, and the first housing 12 The body 12 reaches its middle slide position. At this time, in the slide mechanism 1, the first member 2 slides further upward using the guide members 4 a and 4 b of the second member 3 as guides, and the upper and lower intermediate portions of the first member 2 face the second member 3. Then, the fixing pin 6a fixed to the first member 2 moves to the same height position (vertical position) as the fixing pin 6b fixed to the second member 3, and a straight line connecting the first connecting portion 51a and the second connecting portion 51b. Becomes perpendicular to the sliding direction of the first member 2, and the linear distance between the first connecting portion 51a and the second connecting portion 51b is minimized. In this way, the first connecting portion 51a and the second connecting portion 51b are arranged at the same height position, and the biasing member 5 is located at the slide intermediate position where the linear distance between the first connecting portion 51a and the second connecting portion 51b is minimized. The first spring portion 51c is compressed and deformed to the maximum, and stores the maximum elastic energy. At this time, the first spring portion 51c is swirled by the second spring portions 51d and 51e with respect to the winding end portions of the two second spring portions 51d and 51e around the first connecting portion 51a and the second connecting portion 51b. Apply the maximum load in the direction of winding. Thereby, the spirals of the second spring parts 51d and 51e are maximally wound by the first spring part 51c and store the maximum elastic energy, and at the same time, the wire from the winding end part is fed out to the maximum, and the first spring part 51c. The wire length (spring length) is increased to the maximum, and the stress generated in the first spring portion 51c is reduced. At this time, the urging direction of the urging member 5 is a direction perpendicular to the sliding direction of the first member 2 (first housing 12), and the first member 2 is in either the upward direction or the downward direction. Also does not slide.

続いて、さらに第１筐体１２を上方向へスライドさせると、第１筐体１２は、そのスライド中間位置を越える。第１筐体１２がスライド中間位置を越えた時点で、スライド機構１は、第１連結部５１ａと第２連結部５１ｂの上下の位置関係が逆転し、第１連結部５１ａと第２連結部５１ｂとの直線距離が縮小するスライド工程から拡大するスライド工程に転じる。すなわち第１部材２が第２部材３のガイド部材４ａ，４ｂをガイドとしてさらに上方向へスライドし、第１部材２に固定した固定ピン６ａが第２部材３に固定した固定ピン６ｂよりも上方へ移動し、第１連結部５１ａと第２連結部５１ｂとの直線距離が最小から漸次拡大する。このように第１連結部５１ａと第２連結部５１ｂとの直線距離が拡大するスライド工程に入ったときの付勢部材５は、第１連結部５１ａと第２連結部５１ｂとの直線距離が縮小するスライド工程において第１バネ部５１ｃと第２バネ部５１ｄ，５１ｅに蓄えた弾性エネルギーを開放し、第１連結部５１ａと第２連結部５１ｂとの間の直線距離を拡大しようとする第１バネ部５１ｃによる付勢力によって、第１部材２を上方向へ付勢し、第１筐体１２と一体に第１部材２を第２部材３のガイド部材４ａ，４ｂをガイドとしてさらに上方向へスライドさせる。この際、第２バネ部５１ｄ，５１ｅは、渦巻きが最大に巻き込まれており、しかも蓄えた弾性エネルギーを開放するので、第１バネ部５１ｃの付勢力を固定ピン６ａ，６ｂを介して第１部材２に効率よく伝達し、第１部材２を第１部材２と一体に上方向へスライドさせる。   Subsequently, when the first casing 12 is further slid upward, the first casing 12 exceeds the middle slide position. When the first housing 12 exceeds the intermediate slide position, the slide mechanism 1 has the first and second connecting portions 51a and 51b in an up-and-down positional relationship, and the first and second connecting portions 51a and 51b are reversed. From the slide process in which the linear distance to 51b is reduced, the slide process is increased. That is, the first member 2 slides further upward using the guide members 4 a and 4 b of the second member 3 as a guide, and the fixing pin 6 a fixed to the first member 2 is above the fixing pin 6 b fixed to the second member 3. The linear distance between the first connecting part 51a and the second connecting part 51b gradually increases from the minimum. In this way, the biasing member 5 when the linear distance between the first connecting part 51a and the second connecting part 51b enters the sliding step is such that the linear distance between the first connecting part 51a and the second connecting part 51b is the same. The elastic energy stored in the first spring part 51c and the second spring parts 51d, 51e in the sliding step to be reduced is released, and the linear distance between the first connection part 51a and the second connection part 51b is increased. The first member 2 is urged upward by the urging force of the first spring portion 51 c, and the first member 2 is integrated with the first housing 12, and the guide members 4 a and 4 b of the second member 3 are guided further upward. Slide to. At this time, the second spring portions 51d and 51e are swirled to the maximum and release the stored elastic energy. Therefore, the urging force of the first spring portion 51c is applied to the first springs via the fixing pins 6a and 6b. The first member 2 is slid upward together with the first member 2 by efficiently transmitting to the member 2.

図３，図４，図６に示すように、付勢部材５の付勢力によって、最終的に第１部材２は、第２部材３のガイド部材４ａ，４ｂをガイドとして、上方向へのスライド終端位置までスライドし、第１筐体１２を、上方向へのスライド終端位置である開位置までスライドさせ、その開位置に保持する。この際、第２バネ部５１ｄ，５１ｅは、蓄えた弾性エネルギーを開放しながら、第１バネ部５１ｃの付勢力の一部を吸収してダンパー作用を発揮し、第１部材２が上方向へのスライド終端位置に達したときの衝撃を緩和する。こうして、第１筐体１２を開位置にスライドさせ、第２筐体１３に対して第１筐体１２を上方向に位置ずれさせることにより、第２筐体１３の操作部１６及び送話部１７は完全に出現し、スライド式携帯電話機１１を使用することができる。   As shown in FIGS. 3, 4, and 6, the first member 2 finally slides upward using the guide members 4 a and 4 b of the second member 3 as a guide by the biasing force of the biasing member 5. The first housing 12 is slid to the open position, which is the slide end position in the upward direction, and held at the open position. At this time, while releasing the stored elastic energy, the second spring portions 51d and 51e absorb part of the urging force of the first spring portion 51c and exhibit a damper action, so that the first member 2 moves upward. Mitigates impact when reaching the slide end position. Thus, by sliding the first housing 12 to the open position and shifting the first housing 12 upward with respect to the second housing 13, the operation unit 16 and the transmission unit of the second housing 13. 17 appears completely, and the sliding mobile phone 11 can be used.

第１筐体１２を開位置より元の閉位置にスライドさせるときには、上記と逆の動作（操作）となる。   When the first housing 12 is slid from the open position to the original closed position, the operation (operation) is the reverse of the above.

このように、第１バネ部５１ｃと第２バネ部５１ｄ，５１ｅを複合した線バネ５１の付勢力によって、第１筐体１２を閉位置から手で上方向へスライドさせる際、スライド中間位置の手前で離すとスライド前の閉位置に復帰するが、スライド中間位置を僅かでも超えて離すと第１筐体１２はそのまま開位置まで上方向へスライドする。また、第１筐体１２を開位置より手で下方向へスライドさせる際、スライド中間位置より手前で離すとスライド前の開位置に復帰するが、スライド中間位置を僅かでも超えて離すと第１筐体１２はそのまま閉位置まで下方向へスライドする。すなわち線バネ５１及び一対の揺動アーム５２，５３とで構成した付勢部材５が、第２筐体３に対して第１筐体２が、操作部１６を覆い隠す閉位置と出現する開位置にスライドするのを補助する。   Thus, when the first housing 12 is slid upward from the closed position by hand by the biasing force of the wire spring 51 that is a combination of the first spring portion 51c and the second spring portions 51d and 51e, the slide intermediate position is When it is released in front, it returns to the closed position before the slide, but when it is released slightly beyond the middle slide position, the first housing 12 slides up to the open position as it is. Further, when the first housing 12 is slid downward from the open position by hand, the first housing 12 returns to the open position before the slide if it is released from the slide intermediate position, but the first case is released slightly beyond the slide intermediate position. The housing 12 slides down to the closed position as it is. In other words, the urging member 5 constituted by the wire spring 51 and the pair of swing arms 52 and 53 is opened with the first housing 2 appearing at the closed position where the first housing 2 covers the operation unit 16 with respect to the second housing 3. Assist in sliding into position.

また、第１筐体１２が閉位置と開位置の間でスライドする際、フレキシブル基板１８の中間部は、第１筐体１２の上下方向のスライドに連動して、折り返し部１８ｃの位置を上下方向に変位させながら、付勢部材５を配置した第１部材２と第２部材３の隙間で上下方向にローリングするが、その際、付勢部材５もまた、第１部材１２（第１筐体１２）の上下方向のスライドに連動して、第２部材３に固定している固定ピン６ｂを中心に所定の範囲で回動変位（上下方向に揺動変位）し、第１バネ部５１ｃが、その下側に接近して位置するフレキシブル基板１８の折り返し部１８ｃとの距離を保ちつつ、所定の範囲で回動変位（上下方向に揺動変位）しながら、第１部材１２（第１筐体１２）のスライド範囲の全体にわたり、中央部にフレキシブル基板１８の中間部の上部を下方より挿入配置可能なスペース８、すなわちフレキシブル基板１８の配線スペース８を確保する。   Further, when the first housing 12 slides between the closed position and the open position, the intermediate portion of the flexible substrate 18 moves the position of the folded portion 18 c up and down in conjunction with the vertical sliding of the first housing 12. While displacing in the direction, the urging member 5 rolls in the vertical direction through the gap between the first member 2 and the second member 3 on which the urging member 5 is disposed. In conjunction with the vertical slide of the body 12), the first spring portion 51c is pivotally displaced (oscillated vertically) within a predetermined range around the fixing pin 6b fixed to the second member 3. However, while maintaining a distance from the folded portion 18c of the flexible substrate 18 positioned close to the lower side, the first member 12 (the first member 12 is rotated while being displaced in a predetermined range). Flexi in the center of the entire sliding range of the case 12) Upper insertion from below locatable space of the intermediate portion 8 of the Le substrate 18, i.e., to ensure a wiring space 8 of the flexible substrate 18.

以上のように本実施形態に係るスライド式携帯端末機１１のスライド機構１によれば、表面に表示部１４を設ける第１筐体１２と表面に操作部１６を設ける第２筐体１３をスライド自在に重合連結する板状の第１及び第２部材２，３と、第１部材２と第２部材３の間に配置する付勢部材５を備え、付勢部材５の弾性付勢によって第１部材２と第２部材３の間にスライド方向への付勢が生じるように構成する。また、付勢部材５は、１本の金属線材からなる線バネ５１と相対揺動可能な状態に一端同士を連結した一対の揺動アーム５２，５３で構成されていて、第１部材２に固定されている第１揺動アーム５２に連結する第１連結部５１ａと、第２部材３に固定されている第２揺動アーム５３に連結する第２連結部５１ｂと、第１連結部５１ａと第２連結部５１ｂを結ぶ直線に対してオフセットし、第１連結部５１ａと第２連結部５１ｂを繋ぐ第１バネ部５１ｃと、第１連結部５１ａと第２連結部５１ｂの両方の周囲に渦巻き状に形成し、その第１連結部５１ａと第２連結部５１ｂの両方と第１バネ部５１ｃを繋ぐ２つの第２バネ部５１ｄ，５１ｅを有し、第１バネ部５１ｃと第２バネ部５１ｄ，５１ｅは、同一平面上に配置し、第１バネ部５１ｃは、第１揺動アーム５２の支点部分と第２揺動アームの支点部分との間の直線距離が縮小するスライド工程で、第２バネ部５１ｄ，５１ｅの巻き込み量を大きくするように、その第２バネ部５１ｄ，５１ｅの巻き込み方向に突出している構成とした。   As described above, according to the sliding mechanism 1 of the sliding portable terminal 11 according to the present embodiment, the first casing 12 having the display unit 14 on the surface and the second casing 13 having the operation unit 16 on the surface are slid. A plate-like first and second members 2 and 3 that are freely connected to each other and a biasing member 5 disposed between the first member 2 and the second member 3 are provided. The first member 2 and the second member 3 are configured to be biased in the sliding direction.

The spring portions 51d and 51e are arranged on the same plane, and the first spring portion 51c is In the sliding step in which the linear distance between the fulcrum portion of the first oscillating arm 52 and the fulcrum portion of the second oscillating arm is reduced, the second spring portions 51d and 51e are increased in the second amount so as to increase the amount of winding. The spring portions 51d and 51e are configured to protrude in the winding direction.

そして、第１揺動アーム５２に連結する第１連結部５１aと第２揺動アーム５３に連結する第２連結部５１ｂを結ぶ直線に対してオフセットし、第１連結部５１ａと第２連結部５１ｂを繋ぐ第１バネ部５１ｃを有する線バネ５１は、第１バネ部５１ｃによって、中央部に第１筐体１２と第２筐体１３を電気的に接続するフレキシブル基板１８の配線スペース８を確保できる。   Then, the first connecting portion 51a and the second connecting portion are offset with respect to a straight line connecting the first connecting portion 51a connected to the first swing arm 52 and the second connecting portion 51b connected to the second swing arm 53. The wire spring 51 having the first spring portion 51c connecting the 51b has the wiring space 8 of the flexible substrate 18 that electrically connects the first housing 12 and the second housing 13 to the center portion by the first spring portion 51c. It can be secured.

また、第１揺動アーム５２に連結する第１連結部５１ａと第２揺動アーム５３に連結する第２連結部５１ｂを結ぶ直線に対してオフセットし、第１連結部５１ａと第２連結部５１ｂを繋ぐ第１バネ部５１ｃと、第１連結部５１ａと第２連結部５１ｂの両方の周囲に渦巻き状に形成し、第１連結部５１ａと第２連結部５１ｂの両方と第１バネ部５１ｃを繋ぐ２つの第２バネ部５１ｄ，５１ｅを有し、第１バネ部５１ｃと第２バネ部５１ｄ，５１ｅを、同一平面上に配置する線バネ５１と一対の揺動アーム５２，５３とで構成した付勢部材５は、少なくとも第１部材２への連結部と第２部材３への連結部の間を、線バネ５１と揺動アーム５２，５３の厚みのみで構成することができ、厚みを小さくできる。   Further, the first connecting portion 51a and the second connecting portion are offset with respect to a straight line connecting the first connecting portion 51a connected to the first swing arm 52 and the second connecting portion 51b connected to the second swing arm 53.
