Abstract

An assist spring with which the distance of sliding of a housing by manual operation can be reduced. An assist spring (107) for urging sliding of a first housing (102) of a portable device (100)is provided with a first urging mechanism (110) and a second urging mechanism (111). The first urging mechanism (110) or the second urging mechanism (111) is provided with a limiter member (121) for limiting the amount of compression of the first or the second urging mechanism (110 or 111). The assist spring (107) is mounted between the first housing (102) and a second housing (105) so that, when the first housing (102) is slid, the assist spring (107) is rotated in the sliding direction, changed to a horizontal attitude starting from a manual slide region in which the assist spring is in a first oblique attitude, and changed from the horizontal attitude to be located in an automatic slide region in which the assist spring is in a second oblique attitude. The assist spring (107) is adapted such that the amount of compression of the first urging mechanism (110) or the second urging mechanism (111) is limited in the vicinity of the horizontal attitude by the limiter member (121).

　特許文献１～特許文献５のアシスト機能は、第１の筐体のスライド量を横軸にとり、スライド荷重（スライド方向に発生している荷重）を縦軸にとったスライド荷重曲線を作成すると、手動スライド領域から自動スライド領域に変わる前後の傾きが小さい。よって、第１の筐体が自動スライド領域に入っても、第１の筐体をスライドさせ得る荷重に、すぐには達せず、自動スライド動作が行われないため、手動させるスライド動作距離が長くなる。 The assist functions of Patent Documents 1 to 5 create a slide load curve in which the horizontal axis represents the slide amount of the first housing and the vertical axis represents the slide load (load generated in the slide direction). The tilt before and after changing from the manual slide area to the automatic slide area is small. Therefore, even if the first housing enters the automatic slide area, the load that can slide the first housing is not reached immediately, and the automatic slide operation is not performed. Become.

　本発明を適用した具体的な実施形態について、図面を参照しながら詳細に説明する。ただし、本発明が以下の実施形態に限定される訳ではない。また、説明を明確にするため、以下の記載及び図面は、適宜、簡略化されている。 Specific embodiments to which the present invention is applied will be described in detail with reference to the drawings. However, the present invention is not limited to the following embodiments. In addition, for clarity of explanation, the following description and drawings are simplified as appropriate.
　先ず、直列バネの原理モデルを説明する。直列バネの説明にあたり、図４Ａ～図４Ｅに示す原理モデルを作成した。 First, the principle model of the series spring will be explained. In describing the series spring, the principle model shown in FIGS. 4A to 4E was created.
　図４Ａに示す原理モデルは、バネ定数の等しい二つの圧縮バネ４０３が中子４０２を介して直列に連結されている。ちなみに、図中の符号４０１は先端部を示している。 In the principle model shown in FIG. 4A, two compression springs 403 having the same spring constant are connected in series via a core 402. Incidentally, reference numeral 401 in the figure indicates the tip.
　図４Ｂに示す原理モデルは、圧縮バネ４０５と、圧縮バネ４０５よりバネ定数の小さい圧縮バネ４０４とが、中子４０２を介して直列に連結されている。 In the principle model shown in FIG. 4B, a compression spring 405 and a compression spring 404 having a smaller spring constant than the compression spring 405 are connected in series via a core 402.
　図４Ｃに示す原理モデルは、バネ定数の等しい二つの圧縮バネ４０３が中子４０２を介して直列に連結されており、上側の圧縮バネ４０３の圧縮量を制限するリミッタ４０６が設けられている。 In the principle model shown in FIG. 4C, two compression springs 403 having the same spring constant are connected in series via a core 402, and a limiter 406 for limiting the compression amount of the upper compression spring 403 is provided.
　図４Ｄに示す原理モデルは、圧縮バネ４０５と、圧縮バネ４０５よりバネ定数の小さい圧縮バネ４０４とが、中子４０２を介して直列に連結されており、上側の圧縮バネ４０４の圧縮量を制限するリミッタ４０６が設けられている。 In the principle model shown in FIG. 4D, a compression spring 405 and a compression spring 404 having a smaller spring constant than the compression spring 405 are connected in series via a core 402, and the compression amount of the upper compression spring 404 is limited. A limiter 406 is provided.
　図４Ｅに示す原理モデルは、圧縮バネ４０５と、圧縮バネ４０５よりバネ定数の小さい圧縮バネ４０４とが、中子４０２を介して直列に連結されており、下側の圧縮バネ４０５の圧縮量を制限するリミッタ４０６が設けられている。 In the principle model shown in FIG. 4E, a compression spring 405 and a compression spring 404 having a smaller spring constant than the compression spring 405 are connected in series via a core 402, and the compression amount of the lower compression spring 405 is determined. A limiter 406 for limiting is provided.
　ここで、圧縮バネ４０３のバネ定数をｋ１、圧縮バネ４０４のバネ定数をｋ２、圧縮バネ４０５のバネ定数をｋ３とする。 Here, the spring constant of the compression spring 403 is k1, the spring constant of the compression spring 404 is k2, and the spring constant of the compression spring 405 is k3.
　図４Ａに示す原理モデルは、圧縮バネ４０３による合成バネ定数がＫ＝ｋ１／２となる。 In the principle model shown in FIG. 4A, the combined spring constant by the compression spring 403 is K = k1 / 2.
　図４Ｂに示す原理モデルは、圧縮バネ４０４と圧縮バネ４０５による合成バネ定数がＫ＝（ｋ２×ｋ３）／（ｋ２＋ｋ３）となる。 In the principle model shown in FIG. 4B, the combined spring constant of the compression spring 404 and the compression spring 405 is K = (k2 × k3) / (k2 + k3).
　図４Ｃに示す原理モデルは、リミッタ４０６が作用するまでの圧縮バネ４０３による合成バネ定数がＫ＝ｋ１／２となる。リミッタ４０６が作用した後の圧縮バネ４０３による合成バネ定数がＫ＝ｋ１となる。このとき、リミッタ４０６が圧縮バネ４０３に作用した後の圧縮バネ４０３による合成バネ定数が、ｋ１／２＞ｋ１、つまり、１／２＞１となり得る条件は、あり得ない。 In the principle model shown in FIG. 4C, the combined spring constant by the compression spring 403 until the limiter 406 acts is K = k1 / 2. The combined spring constant by the compression spring 403 after the limiter 406 acts is K = k1. At this time, there can be no condition that the combined spring constant of the compression spring 403 after the limiter 406 acts on the compression spring 403 can satisfy k1 / 2> k1, that is, 1/2> 1.
　図４Ｄに示す原理モデルは、リミッタ４０６が作用するまでの圧縮バネ４０４と圧縮バネ４０５による合成バネ定数がＫ＝（ｋ２×ｋ３）／（ｋ２＋ｋ３）となる。リミッタ４０６が作用した後の圧縮バネ４０４と圧縮バネ４０５による合成バネ定数がＫ＝ｋ３となる。このとき、リミッタ４０６が圧縮バネ４０４に作用した後の圧縮バネ４０４と圧縮バネ４０５による合成バネ定数が、（ｋ２×ｋ３）／（ｋ２＋ｋ３）＞ｋ３、つまり、０＞ｋ３となり得る条件はあり得ない。 In the principle model shown in FIG. 4D, the combined spring constant by the compression spring 404 and the compression spring 405 until the limiter 406 acts is K = (k2 × k3) / (k2 + k3). The combined spring constant of the compression spring 404 and the compression spring 405 after the limiter 406 acts is K = k3. At this time, there may be a condition that the combined spring constant of the compression spring 404 and the compression spring 405 after the limiter 406 acts on the compression spring 404 is (k2 × k3) / (k2 + k3)> k3, that is, 0> k3. Absent.
　図４Ｅに示す原理モデルは、リミッタ４０６が作用するまでの圧縮バネ４０４と圧縮バネ４０５による合成バネ定数がＫ＝（ｋ２×ｋ３）／（ｋ２＋ｋ３）となる。リミッタ４０６が作用した後の圧縮バネ４０４と圧縮バネ４０５による合成バネ定数がＫ＝ｋ２となる。このとき、リミッタ４０６が圧縮バネ４０５に作用した後の前記圧縮バネ４０５と圧縮バネ４０４による合成バネ定数が、（ｋ２×ｋ３）／（ｋ２＋ｋ３）＞ｋ２、つまり、０＞ｋ２となり得る条件はあり得ない。 In the principle model shown in FIG. 4E, the combined spring constant by the compression spring 404 and the compression spring 405 until the limiter 406 acts is K = (k2 × k3) / (k2 + k3). The combined spring constant of the compression spring 404 and the compression spring 405 after the limiter 406 has acted is K = k2. At this time, there is a condition that the combined spring constant of the compression spring 405 and the compression spring 404 after the limiter 406 acts on the compression spring 405 can be (k2 × k3) / (k2 + k3)> k2, that is, 0> k2. I don't get it.
　よって、合成バネ定数はリミッタ４０６が作用した後の傾きが必ず大きくなり、図示すると、図５に示すようなグラフになる。ちなみに、図５において、直線Ｋは、図４Ａ、図４Ｂの原理モデルの先端４０１の移動量ｘと、発生荷重ｆとの関係を示している。直線ｋ１は、図４Ｃの原理モデルにおいて、リミッタ４０６が作用した後の先端４０１の移動量ｘと、発生荷重ｆとの関係を示している。直線ｋ２は、図４Ｅの原理モデルにおいて、リミッタ４０６が作用した後の先端４０１の移動量ｘと、発生荷重ｆとの関係を示している。直線ｋ３は、図４Ｄの原理モデルにおいて、リミッタ４０６が作用した後の先端４０１の移動量ｘと、発生荷重ｆとの関係を示している。
　本発明のアシストバネ、携帯機器及び携帯機器の開閉付勢方法は、上記直列バネの原理を用いたものである。
　以下、具体的な実施形態について説明する。 Therefore, the composite spring constant always has a large inclination after the limiter 406 is actuated, and a graph as shown in FIG. 5 is obtained. Incidentally, in FIG. 5, a straight line K indicates the relationship between the amount of movement x of the tip 401 of the principle model of FIGS. 4A and 4B and the generated load f. The straight line k1 indicates the relationship between the amount of movement x of the tip 401 after the limiter 406 has acted and the generated load f in the principle model of FIG. 4C. The straight line k2 indicates the relationship between the amount of movement x of the tip 401 after the limiter 406 has acted and the generated load f in the principle model of FIG. 4E. The straight line k3 indicates the relationship between the amount of movement x of the tip 401 after the limiter 406 has acted and the generated load f in the principle model of FIG. 4D.
The assist spring, the portable device, and the opening / closing biasing method of the portable device of the present invention use the principle of the series spring.
Hereinafter, specific embodiments will be described.

　第２の付勢機構１１１は、アシストベース１１３と、圧縮バネ１１７と、ピストンロッド１１８と、を備えている。アシストベース１１３は、第１の付勢機構１１０と共通の部材である。アシストベース１１３は、当該側面１１３ａと対峙する側面１１３ｂに開口部１１６ａを有し、長穴１１２と平行に長穴１１６が形成されている。圧縮バネ１１７は、長穴１１６に挿入されている。ピストンロッド１１８は、当該長穴１１６に、圧縮バネ１１７の圧縮力及び伸長力が伝達可能に挿入されており、端部が第２の筐体１０５に回転可能に連結されている。 The second urging mechanism 111 includes an assist base 113, a compression spring 117, and a piston rod 118. The assist base 113 is a member common to the first urging mechanism 110. The assist base 113 has an opening 116 a on a side surface 113 b facing the side surface 113 a, and an elongated hole 116 is formed in parallel with the elongated hole 112. The compression spring 117 is inserted into the elongated hole 116. The piston rod 118 is inserted into the elongated hole 116 so that the compression force and the extension force of the compression spring 117 can be transmitted, and an end portion thereof is rotatably connected to the second housing 105.
　アシストベース１１３は、圧縮バネ１１４、１１７の圧縮力などに十分に耐え得る強度を有する矩形部材である。アシストベース１１３は、合計四本の長穴１１２と１１６とが互い違いに配置されている。 The assist base 113 is a rectangular member having a strength that can sufficiently withstand the compression force of the compression springs 114 and 117. The assist base 113 has a total of four elongated holes 112 and 116 arranged alternately.
　長穴１１２（１１６）は、一端部のみに開口部１１２ａ（１１６ａ）を有する。長穴１１２（１１６）は、挿入したピストンロッド１１５（１１８）が振られないように、ピストンロッド１１５（１１８）の外径と略等しい内径を有する。長穴１１２（１１６）は、圧縮バネ１１４（１１７）及びピストンロッド１１５（１１８）の先端部を挿入することができる深さを有する。 The long hole 112 (116) has an opening 112a (116a) only at one end. The long hole 112 (116) has an inner diameter substantially equal to the outer diameter of the piston rod 115 (118) so that the inserted piston rod 115 (118) is not shaken. The long hole 112 (116) has a depth capable of inserting the compression spring 114 (117) and the tip of the piston rod 115 (118).
　圧縮バネ１１４（１１７）は、長穴１１２（１１６）の内径と略等しい外径を有する。本実施形態では圧縮バネ１１４（１１７）は等しいバネ定数を有する。 The compression spring 114 (117) has an outer diameter substantially equal to the inner diameter of the long hole 112 (116). In the present embodiment, the compression spring 114 (117) has an equal spring constant.
　ピストンロッド１１５（１１８）は、圧縮バネ１１４（１１７）の圧縮力などに十分に耐え得る強度を有する丸棒部材である。ピストンロッド１１５（１１８）の先端部は、圧縮バネ１１４（１１７）と接触する。ピストンロッド１１５（１１８）の他端部は、同一の付勢機構に属する他のピストンロッドの他端部と連結部材１１９により連結されている。 The piston rod 115 (118) is a round bar member having sufficient strength to withstand the compression force of the compression spring 114 (117). The tip of the piston rod 115 (118) contacts the compression spring 114 (117). The other end of the piston rod 115 (118) is connected to the other end of another piston rod belonging to the same urging mechanism by a connecting member 119.
　連結部材１１９には、ボルト（図示は省略）を通す穴１２０が形成されている。連結部材１１９は、軸受（図示は省略）を介して穴１２０に通されたボルトを、各々の筐体に固定して連結されている。 The connection member 119 has a hole 120 through which a bolt (not shown) is passed. The connecting member 119 is connected to each casing by fixing bolts passed through the holes 120 via bearings (not shown).
　第１の付勢機構１１０のピストンロッド１１５の他端部近傍には、リミッタ部材１２１が設けられている、リミッタ部材１２１には、ピストンロッド１１５が内部を貫通する。リミッタ部材１２１は、ピストンロッド１１５のストローク量を制限し、圧縮バネ１１４の圧縮量を制限することができる部材であれば、特に限定されない。このリミッタ部材１２１は、詳細は後述するが、第１の筐体１０２をスライドさせた際に、アシストバネ１０７が水平姿勢となる前後にわたって、ピストンロッド１１５のストロークが制限される位置に、アシストベース側の側面が配置されている。 A limiter member 121 is provided in the vicinity of the other end of the piston rod 115 of the first urging mechanism 110, and the piston rod 115 penetrates the limiter member 121. The limiter member 121 is not particularly limited as long as it is a member that can limit the stroke amount of the piston rod 115 and limit the compression amount of the compression spring 114. Although the limiter member 121 will be described in detail later, when the first casing 102 is slid, the assist base 107 is positioned at a position where the stroke of the piston rod 115 is restricted before and after the assist spring 107 assumes a horizontal posture. Side surfaces are arranged.
　このような構成のアシストバネ１０７は、上述した直列バネと同様の原理で作動する。すなわち、アシストバネ１０７は、圧縮バネ１１４、１１７のバネ定数を等しくｋ１とすると、リミッタ部材１２１が作用するまでは、圧縮バネ１１４と１１７による合成バネ定数がｋ１／２となる。一方、アシストバネ１０７は、リミッタ部材１２１が作用した後は、圧縮バネ１１４と１１７による合成バネ定数がｋ１となる。 The assist spring 107 having such a configuration operates on the same principle as the series spring described above. In other words, if the spring constants of the compression springs 114 and 117 are equal to k1, the assist spring 107 has a combined spring constant of k1 / 2 until the limiter member 121 operates. On the other hand, after the limiter member 121 acts on the assist spring 107, the combined spring constant of the compression springs 114 and 117 becomes k1.
　このアシストバネ１０７は、図１Ｂ及び図３に示すように、第１の筐体１０２と第２の筐体１０５との間に配置されている。つまり、アシストバネ１０７は、第２の付勢機構１１１のピストンロッド１１８の連結部材１１９と第２の筐体１０５との連結点を中心として回転し、第１の筐体１０２のスライドを付勢するように、圧縮した状態で配置されている。具体的にいうと、第１の筐体１０２をスライドさせると、アシストバネ１０７は、回転して第１の斜め姿勢である手動スライド領域から水平姿勢となる。アシストバネ１０７は、さらに回転して水平姿勢から第２の斜め姿勢である自動スライド領域に移行する。 The assist spring 107 is disposed between the first casing 102 and the second casing 105 as shown in FIGS. 1B and 3. That is, the assist spring 107 rotates around the connection point between the connecting member 119 of the piston rod 118 of the second urging mechanism 111 and the second housing 105 to urge the slide of the first housing 102. To be arranged in a compressed state. More specifically, when the first housing 102 is slid, the assist spring 107 rotates and assumes a horizontal posture from the manual slide region that is in the first oblique posture. The assist spring 107 further rotates and shifts from the horizontal posture to the automatic slide region in the second oblique posture.
　このような構成の携帯機器１００は、図３Ａ～図３Ｅに示すように第１の筐体１０２が付勢されてスライドする。 In the mobile device 100 having such a configuration, the first casing 102 is urged and slides as shown in FIGS. 3A to 3E.
　図３Ａは、第１の筐体１０２が、第２の筐体１０５に対して閉じた状態を示している。このとき、アシストバネ１０７は、第１の斜め姿勢である左下に傾いた姿勢で配置される。 FIG. 3A shows a state in which the first housing 102 is closed with respect to the second housing 105. At this time, the assist spring 107 is arranged in a posture inclined to the lower left, which is the first oblique posture.
　この状態において、第１の筐体１０２が、第２の筐体１０５に対して相対的に移動した量を、スライド量Ｘとすると、Ｘ＝Ｘｄ＝０となる。また、この状態において、アシストバネ１０７の圧縮バネ１１４と１１７が圧縮して発生する長手方向（鉛直方向）の荷重を、スライド荷重Ｆ（Ｘ）とすると、Ｆ（Ｘ）＝Ｆ（Ｘｄ）となる。このとき、スライド荷重は、大きさ｜Ｆ（Ｘｄ）｜で、第１の筐体１０２が閉じる方向に発生している。 In this state, if the amount of movement of the first housing 102 relative to the second housing 105 is the slide amount X, X = Xd = 0. In this state, if the load in the longitudinal direction (vertical direction) generated by compression of the compression springs 114 and 117 of the assist spring 107 is a slide load F (X), F (X) = F (Xd) Become. At this time, the slide load has a magnitude | F (Xd) | and is generated in a direction in which the first housing 102 is closed.
　図３Ｂは、図３Ａの状態から、手動で第１の筐体１０２を、第２の筐体１０５に対して、Ｘｅスライドさせてリミッタ部材１２１を作用させた状態を示している。つまり、第１の付勢機構１１０の連結部材１１９とアシストベース１１３の側面との間にリミッタ部材１２１が挟まってピストンロッド１１５のストロークが制限されている。 FIG. 3B shows a state in which the limiter member 121 is acted by manually sliding the first casing 102 from the state of FIG. 3A with respect to the second casing 105 by Xe. In other words, the limiter member 121 is sandwiched between the connecting member 119 of the first urging mechanism 110 and the side surface of the assist base 113 to limit the stroke of the piston rod 115.
　この状態において、第１の筐体１０２のスライド量はＸ＝Ｘｅとなる。また、この状態において、スライド荷重はＦ（Ｘ）＝Ｆ（Ｘｅ）となる。このとき、スライド荷重は、大きさ｜Ｆ（Ｘｅ）｜で、第１の筐体１０２が閉じる方向に発生している。 In this state, the slide amount of the first housing 102 is X = Xe. In this state, the slide load is F (X) = F (Xe). At this time, the slide load has a magnitude | F (Xe) | and is generated in a direction in which the first housing 102 is closed.
　図３Ｃは、図３Ａの状態から、手動で第１の筐体１０２を、第２の筐体１０５に対して、Ｘｆスライドさせてリミッタ部材１２１を作用させた状態でアシストバネ１０７を水平姿勢とした状態を示している。 FIG. 3C shows a state in which the assist spring 107 is in a horizontal posture in a state in which the first casing 102 is manually slid Xf relative to the second casing 105 from the state of FIG. Shows the state.
　この状態において、第１の筐体１０２のスライド量はＸ＝Ｘｆとなる。また、この状態において、スライド荷重はＦ（Ｘ）＝Ｆ（Ｘｆ）となる。このとき、スライド荷重は、アシストバネ１０７が水平姿勢であるので、大きさ｜Ｆ（Ｘｆ）｜は０の平衡状態となる。 In this state, the slide amount of the first housing 102 is X = Xf. In this state, the slide load is F (X) = F (Xf). At this time, since the assist spring 107 is in a horizontal posture, the magnitude | F (Xf) |
　図３Ｄは、図３Ｃの状態から、自動で第１の筐体１０２を、第２の筐体１０５に対して、リミッタ部材１２１を作用させた状態でＸｇ－Ｘｆスライドさせた状態を示している。 FIG. 3D shows a state in which the first housing 102 is automatically slid Xg-Xf from the state of FIG. 3C with the limiter member 121 acting on the second housing 105. .
　この状態において、第１の筐体１０２のスライド量はＸ＝Ｘｇとなる。また、この状態において、スライド荷重はＦ（Ｘ）＝Ｆ（Ｘｇ）となる。このとき、スライド荷重は、大きさ｜Ｆ（Ｘｇ）｜で、第１の筐体１０２が開く方向に発生している。 In this state, the slide amount of the first housing 102 is X = Xg. In this state, the slide load is F (X) = F (Xg). At this time, the slide load has a magnitude | F (Xg) | and is generated in the direction in which the first housing 102 opens.
　図３Ｅは、図３Ｃの状態から、自動で第１の筐体１０２を、第２の筐体１０５に対して、リミッタ部材１２１が解除された状態でＸｈ－Ｘｆスライドさせた状態を示している。 FIG. 3E shows a state in which the first casing 102 is automatically slid Xh-Xf with respect to the second casing 105 with the limiter member 121 released from the state of FIG. 3C. .
　この状態において、第１の筐体１０２のスライド量はＸ＝Ｘｈとなる。また、この状態において、スライド荷重はＦ（Ｘ）＝Ｆ（Ｘｈ）となる。このとき、スライド荷重は、大きさ｜Ｆ（Ｘｈ）｜で、第１の筐体１０２が開く方向に発生している。 In this state, the slide amount of the first housing 102 is X = Xh. In this state, the slide load is F (X) = F (Xh). At this time, the slide load has a magnitude | F (Xh) | and is generated in the direction in which the first housing 102 opens.
　このように、携帯機器１００は、直列バネの原理により、リミッタ部材１２１が作用する図３Ｂから図３Ｄに至る状態までアシストバネ１０７のバネ定数が大きくなる。図３Ｃから図３Ｄに至る状態では、アシストバネ１０７が比較的水平姿勢に近い。そのため、アシストバネ１０７の伸長力における鉛直成分が少ないが、アシストバネ１０７は図３Ｃから図３Ｄに至る段階でバネ定数が大きいので、大きなスライド荷重を得ることができる。すなわち、第１の筐体１０２のスライド量を横軸にとり、スライド荷重を縦軸にとったスライド荷重曲線を作成すると、手動スライド領域から自動スライド領域に変わる前後の傾きが大きくなる。よって、第１の筐体１０２が自動スライド領域に入ると、第１の筐体１０２をスライドさせるのに十分な荷重をすぐに得ることができ、手動させるスライド長さを短くすることができる。 Thus, in the portable device 100, the spring constant of the assist spring 107 increases from the state shown in FIG. 3B where the limiter member 121 acts to the state shown in FIG. In the state from FIG. 3C to FIG. 3D, the assist spring 107 is relatively close to the horizontal posture. Therefore, although the vertical component in the extension force of the assist spring 107 is small, the assist spring 107 has a large spring constant in the stage from FIG. 3C to FIG. 3D, so that a large slide load can be obtained. That is, when a slide load curve is created with the slide amount of the first housing 102 taken on the horizontal axis and the slide load taken on the vertical axis, the inclination before and after changing from the manual slide region to the automatic slide region increases. Therefore, when the first housing 102 enters the automatic slide region, a load sufficient to slide the first housing 102 can be obtained immediately, and the slide length to be manually operated can be shortened.
　しかも、アシストバネ１０７は大きなスライド荷重を発生する。そのため、自動スライド領域のスライド長さを、手動スライド領域のスライド長さより長くなるように、アシストバネ１０７を配置する。これにより、手動スライド領域のスライド長さを短くした分だけ、手動させるスライド長さを短くすることができる。 Moreover, the assist spring 107 generates a large slide load. For this reason, the assist spring 107 is arranged so that the slide length of the automatic slide area is longer than the slide length of the manual slide area. Thereby, the slide length to be manually operated can be shortened by the amount corresponding to the shortening of the slide length of the manual slide region.
　ちなみに、図３Ｅの状態から第１の筐体１０２を閉じる場合は、図３Ａから図３Ｅに至る流れとは逆の流れとなる。つまり、図３Ｅから図３Ｃに至る状態までが第１の斜め姿勢である手動スライド領域となる。図３Ｃから図３Ａに至る状態までが第２の斜め姿勢である自動スライド領域となる。そのため、第１の筐体１０２を閉じる際にも、第１の筐体１０２が自動スライド領域に入ると、第１の筐体１０２をスライドさせるのに十分な荷重をすぐに得ることができ、手動させるスライド長さを短くすることができる。 Incidentally, when the first casing 102 is closed from the state of FIG. 3E, the flow is the reverse of the flow from FIG. 3A to FIG. 3E. That is, the state from FIG. 3E to FIG. 3C is the manual slide region in the first oblique posture. The state from FIG. 3C to FIG. 3A is an automatic slide region having the second oblique posture. Therefore, even when the first casing 102 is closed, if the first casing 102 enters the automatic slide region, a load sufficient to slide the first casing 102 can be obtained immediately. The slide length to be manually operated can be shortened.
　＜実施形態２＞
　上記実施形態１は、圧縮バネ１１４と１１７のバネ定数が等しい構成とされているが、この限りでない。一方の付勢機構の圧縮バネのバネ定数が、他方の付勢機構の圧縮バネのバネ定数より小さい構成でも、同様の作用、効果を得ることができる。このとき、リミッタ部材を備えた付勢機構側の圧縮バネのバネ定数が、他方の付勢機構の圧縮バネのバネ定数より小さいことが好ましい。これにより、より大きなスライド荷重を得ることができる。 <Embodiment 2>
In the first embodiment, the compression springs 114 and 117 have the same spring constant, but this is not restrictive. Even if the spring constant of the compression spring of one biasing mechanism is smaller than the spring constant of the compression spring of the other biasing mechanism, the same action and effect can be obtained. At this time, it is preferable that the spring constant of the compression spring on the biasing mechanism side including the limiter member is smaller than the spring constant of the compression spring of the other biasing mechanism. Thereby, a larger slide load can be obtained.
　＜実施形態３＞
　上記実施形態１は、リミッタ部材１２１を第１の付勢機構１１０のピストンロッド１１５の他端部近傍に設けたが、この限りでない。 <Embodiment 3>
In the first embodiment, the limiter member 121 is provided in the vicinity of the other end of the piston rod 115 of the first urging mechanism 110, but this is not restrictive.
　本実施形態のアシストバネ２０７は、図６及び図７に示すように、第１の付勢機構１１０及び第２の付勢機構１１１のピストンロッド１１５、１１８の先端にガイドロッド２０１が形成されている。ガイドロッド２０１は、圧縮バネ１１４、１１７の内部に挿入できるようにピストンロッド１１５、１１８より小径である。このガイドロッド２０１を圧縮バネ１１４（１１７）内に挿入する。これにより、圧縮バネ１１４（１１７）の変形時に前記圧縮バネ１１４（１１７）の撓みを防止することができる。 As shown in FIGS. 6 and 7, the assist spring 207 of the present embodiment has a guide rod 201 formed at the tip of the piston rods 115 and 118 of the first urging mechanism 110 and the second urging mechanism 111. Yes. The guide rod 201 has a smaller diameter than the piston rods 115 and 118 so that the guide rod 201 can be inserted into the compression springs 114 and 117. The guide rod 201 is inserted into the compression spring 114 (117). Accordingly, it is possible to prevent the compression spring 114 (117) from being bent when the compression spring 114 (117) is deformed.
　アシストベース１１３には、長穴１１２（１１６）と軸を共通にするガイド穴２０２が、長穴１１２（１１６）から延長するように形成されている。そして、第１の付勢機構１１０のガイド穴２０２の底部にリミッタ部材２０３が配置されている。そのため、本実施形態の携帯機器も、上記実施形態１の携帯機器１００と同様の作用、効果を得ることができ、第１の筐体１０２が自動スライド領域に入ると、第１の筐体１０２をスライドさせるのに十分な荷重をすぐに得ることができ、手動させるスライド長さを短くすることができる。 The assist base 113 is formed with a guide hole 202 having a common axis with the elongated hole 112 (116) so as to extend from the elongated hole 112 (116). A limiter member 203 is disposed at the bottom of the guide hole 202 of the first urging mechanism 110. Therefore, the mobile device of the present embodiment can also obtain the same operations and effects as the mobile device 100 of the first embodiment. When the first housing 102 enters the automatic slide region, the first housing 102 is obtained. A sufficient load can be obtained immediately to slide the slide, and the slide length to be manually operated can be shortened.
　なお、図８及び図９に示すアシストバネ３０７のように、ガイドロッド２０１の先端にリミッタ部材３０３を設けても、略同様に実施できる。 In addition, even if the limiter member 303 is provided at the tip of the guide rod 201 like the assist spring 307 shown in FIGS.
　＜実施形態４＞
　以上に、本発明のアシストバネ、携帯機器及び携帯機器の開閉付勢方法の実施形態を種々、説明したが、この限りでない。本願発明の構成や詳細には、本願発明のスコープ内で当業者が理解し得る様々な変更をすることができる。 <Embodiment 4>
Although various embodiments of the assist spring, the portable device, and the portable device opening / closing biasing method of the present invention have been described above, the present invention is not limited thereto. Various changes that can be understood by those skilled in the art can be made to the configuration and details of the present invention within the scope of the present invention.
　すなわち、上記実施形態のアシストバネは、リミッタ部材１２１を第１の付勢機構１１０のピストンロッド１１５の他端部近傍に設けた。図１０に示すアシストバネ４０７のように、リミッタ部材１２１をピストンロッド１１５のアシストベース１１３側に設け、ピストンロッド１１５がリミッタ部材１２１内をスライドする構成でも良い。要するに、リミッタ部材１２１をアシストベース１１３の外方に配置する場合は、リミッタ部材１２１はピストンロッド１１５の他端部とアシストベースの側面１１３ａとの間に配置されていれば良い。 That is, in the assist spring of the above embodiment, the limiter member 121 is provided in the vicinity of the other end of the piston rod 115 of the first biasing mechanism 110. Like the assist spring 407 shown in FIG. 10, the limiter member 121 may be provided on the assist base 113 side of the piston rod 115, and the piston rod 115 may slide within the limiter member 121. In short, when the limiter member 121 is disposed outside the assist base 113, the limiter member 121 may be disposed between the other end of the piston rod 115 and the side surface 113a of the assist base.
　また、上記実施形態のアシストバネは、第１の付勢機構１１０と第２の付勢機構１１１とを互い違いに配置した。図１１に示すアシストバネ５０７のように、各々の付勢機構を隣接させて配置しても良い。また、アシストバネは、第１の付勢機構１１０で第２の付勢機構１１１を挟み込むように配置しても良い。要するに、第１の付勢機構１１０と第２の付勢機構１１１との配置は、特に制限されない。 In the assist spring of the above embodiment, the first urging mechanisms 110 and the second urging mechanisms 111 are alternately arranged. Like the assist spring 507 shown in FIG. 11, the respective biasing mechanisms may be arranged adjacent to each other. Further, the assist spring may be arranged so as to sandwich the second urging mechanism 111 by the first urging mechanism 110. In short, the arrangement of the first urging mechanism 110 and the second urging mechanism 111 is not particularly limited.
　また、上記実施形態のアシストバネは、第１の付勢機構及び第２の付勢機構をそれぞれ二個ずつ有するが、個数は特に制限されない。 Further, the assist spring of the above embodiment has two each of the first urging mechanism and the second urging mechanism, but the number is not particularly limited.
　勿論、上記実施形態のアシストバネは、第１の付勢機構がリミッタ部材を備えているが、第２の付勢機構が備えていても良い。 Of course, in the assist spring of the above embodiment, the first urging mechanism is provided with the limiter member, but the second urging mechanism may be provided.
　本発明のアシストバネ、携帯機器及び携帯機器の開閉付勢方法は、上述した形態を組み合わせて良好に実施できる。 The assist spring, portable device, and portable device opening / closing biasing method of the present invention can be well implemented by combining the above-described embodiments.
　＜実施例１＞
　本発明に係るアシストバネ、携帯機器及び携帯機器の開閉付勢方法の実施例１を、図１２～図１９に基づいて説明する。 <Example 1>
First Embodiment An assist spring, a portable device, and a portable device opening / closing biasing method according to a first embodiment of the present invention will be described with reference to FIGS.
　図１２に示すアシストバネ１００７は、上記実施形態１に対応する構成とされており、両付勢機構１０１０、１０１１の圧縮バネ１０１４、１０１７のバネ定数が等しい。圧縮バネ１０１４、１０１７には、バネ定数：１５ｇｆ／ｍｍ、自然長：２０ｍｍ、外径：１．０ｍｍ、線径：０．１５ｍｍの圧縮バネと、バネ定数：１５ｇｆ／ｍｍ、自然長：２５ｍｍ、外径：１．０ｍｍ、線径：０．１５ｍｍの圧縮バネとの二種類を用いた。ちなみに、図中の符号Ｘｐは、ピストンロッド１０１５にリミッタ部材１０２１が作用するまでのストローク長さを示し、符号１０１８は、第２の付勢機構１０１１のピストンロッドを示している。 The assist spring 1007 shown in FIG. 12 is configured to correspond to the first embodiment, and the spring constants of the compression springs 1014 and 1017 of both biasing mechanisms 1010 and 1011 are equal. For compression springs 1014 and 1017, spring constant: 15 gf / mm, natural length: 20 mm, outer diameter: 1.0 mm, wire diameter: 0.15 mm, spring constant: 15 gf / mm, natural length: 25 mm, Two types of compression springs having an outer diameter of 1.0 mm and a wire diameter of 0.15 mm were used. Incidentally, the symbol Xp in the figure indicates the stroke length until the limiter member 1021 acts on the piston rod 1015, and the symbol 1018 indicates the piston rod of the second urging mechanism 1011.
　このアシストバネ１００７を、図１３に示す軌跡を辿り、手動スライド領域のスライド長さと自動スライド領域のスライド長さが等しくなるように、携帯機器に配置した。 The assist spring 1007 is arranged on the portable device so that the slide length of the manual slide area and the slide length of the automatic slide area are equal to each other along the locus shown in FIG.
　このような構成のアシストバネ１００７を備えた携帯機器は、図１４に示すようなスライド荷重曲線を示す。曲線１は、リミッタ部材を備えず、その他の構成を等しくした携帯機器のスライド荷重曲線を示す。曲線２は、Ｘｐ＝１０ｍｍのアシストバネを備えた携帯機器のスライド荷重曲線を示す。曲線３は、Ｘｐ＝７ｍｍのアシストバネを備えた携帯機器のスライド荷重曲線を示す。なお、アシストバネには、上述のように二種類の圧縮バネを使い分けたが、同様の曲線を示した。 The portable device provided with the assist spring 1007 having such a configuration shows a slide load curve as shown in FIG. Curve 1 shows a slide load curve of a portable device that is not provided with a limiter member and has the same configuration. Curve 2 shows a slide load curve of a portable device having an assist spring with Xp = 10 mm. Curve 3 shows a slide load curve of a portable device having an assist spring with Xp = 7 mm. As the assist spring, two types of compression springs were used properly as described above, but the same curves were shown.

Curve 2 shows a slide load curve of a portable device provided with an assist spring 2007 with Xp = 18 mm. Curve 3 shows a slide load curve of a portable device provided with an assist spring 2007 with Xp = 16 mm. As the assist spring, two types of compression springs were used properly as described above, but the same curves were shown.
　図１６では０ｍｍ～３０ｍｍが手動スライド領域のスライド長さを示し、３０ｍｍ～６０ｍｍが自動スライド領域のスライド長さを示す。曲線２、３は曲線１に比べて、手動スライド領域から自動スライド領域に変わる前後で傾きが大きくなっているのが分かる。 In FIG. 16, 0 mm to 30 mm indicates the slide length of the manual slide area, and 30 mm to 60 mm indicates the slide length of the automatic slide area. It can be seen that the slopes of the curves 2 and 3 are larger than those of the curve 1 before and after the manual slide area is changed to the automatic slide area.
　更に、図１７に示すアシストバネ３００７は、上記図１５の構成と略同様の構成とされているが、リミッタ部材３０２１を第２の付勢機構２０１１に備えている。 Furthermore, the assist spring 3007 shown in FIG. 17 has a configuration substantially similar to the configuration shown in FIG. 15, but includes a limiter member 3021 in the second urging mechanism 2011.
　このアシストバネ３００７を、図１３に示す軌跡を辿り、手動スライド領域のスライド長さと自動スライド領域のスライド長さが等しくなるように、携帯機器に配置した。 The assist spring 3007 is disposed on the portable device so that the slide length of the manual slide area and the slide length of the automatic slide area are equal to each other along the locus shown in FIG.
　このような構成のアシストバネ３００７を備えた携帯機器は、図１８に示すようなスライド荷重曲線を示す。曲線１は、リミッタ部材を備えず、その他の構成を等しくした携帯機器のスライド荷重曲線を示す。曲線２は、Ｘｐ＝８ｍｍのアシストバネ３００７を備えた携帯機器のスライド荷重曲線を示す。曲線３は、Ｘｐ＝１０ｍｍのアシストバネ３００７を備えた携帯機器のスライド荷重曲線を示す。なお、アシストバネには、上述のように二種類の圧縮バネを使い分けたが、同様の曲線を示した。 The portable device provided with the assist spring 3007 having such a configuration shows a slide load curve as shown in FIG.

It can be seen that the slopes of the curves 2 and 3 are larger than those of the curve 1 before and after the manual slide area is changed to the automatic slide area.
　ここで、自動スライド領域に入っても、手動でないと自動スライドしない条件を、スライド荷重で５０ｇｆとすると、図１９に示すように、曲線２の手動スライド領域のスライド長さは３３ｍｍで、曲線１の手動スライド領域のスライド長さは３４ｍｍとなる。すなわち、手動スライド領域のスライド長さの低減量は１ｍｍとなる。よって、低減量の割合は、１／３４×１００＝３％である。 Here, even if the automatic slide region is entered, if the slide load is 50 gf unless the manual slide is performed manually, the slide length of the manual slide region of curve 2 is 33 mm and curve 1 as shown in FIG. The slide length of the manual slide area is 34 mm. That is, the amount of reduction in the slide length of the manual slide area is 1 mm. Therefore, the ratio of the reduction amount is 1/34 × 100 = 3%.
　＜実施例２＞
　本発明に係るアシストバネ、携帯機器及び携帯機器の開閉付勢方法の実施例２を、図２０～図２２に基づいて説明する。 <Example 2>

　本実施例は、図１５に示した構成のアシストバネ２００７を、図２０の実線に示す軌跡を辿り、手動スライド領域のスライド長さが自動スライド領域のスライド長さより短くなるように、携帯機器に配置した。ちなみに、図中の符号ΔＸは、アシストバネ２００７のずらし量を示している。 In the present embodiment, the assist spring 2007 having the configuration shown in FIG. 15 is traced along the locus shown by the solid line in FIG. 20 so that the slide length of the manual slide area is shorter than the slide length of the automatic slide area. Arranged. Incidentally, the symbol ΔX in the figure indicates the shift amount of the assist spring 2007.
　このような構成のアシストバネ２００７を備えた携帯機器は、図２１に示すようなスライド荷重曲線を示す。曲線１は、リミッタ部材を備えず、その他の構成を等しくしたアシストバネを、図２０の点線に示す軌跡を辿り、手動スライド領域のスライド長さと自動スライド領域のスライド長さとが等しくなるように配置した携帯機器のスライド荷重曲線を示す。曲線２は、リミッタ部材を備えず、その他の構成を等しくしたアシストバネを、図２０の実線に示す軌跡を辿り、手動スライド領域のスライド長さが自動スライド領域のスライド長さより短くなるように配置した携帯機器のスライド荷重曲線を示す。曲線３は、Ｘｐ＝１８ｍｍのアシストバネ２００７を備えた携帯機器のスライド荷重曲線を示す。なお、アシストバネ２００７には、上述のように二種類の圧縮バネを使い分けたが、同様の曲線を示した。 The portable device provided with the assist spring 2007 having such a configuration shows a slide load curve as shown in FIG. Curve 1 is provided with an assist spring that does not include a limiter member and has the same configuration as the other, so that the slide length of the manual slide area is equal to the slide length of the automatic slide area by following the locus shown by the dotted line in FIG. The slide load curve of a portable device is shown. Curve 2 is provided with an assist spring having no limiter member and the other components being equal so that the slide length of the manual slide area is shorter than the slide length of the automatic slide area, following the locus shown by the solid line in FIG. The slide load curve of a portable device is shown. Curve 3 shows a slide load curve of a portable device provided with an assist spring 2007 with Xp = 18 mm. As the assist spring 2007, two types of compression springs were used properly as described above, but the same curve was shown.
　図２１及び図２２に示すように、アシストバネ２００７のずらし量ΔＸ＝５ｍｍにより、曲線２、３は、曲線１に比べて、手動スライド領域のスライド長さが５ｍｍ低減される。 As shown in FIGS. 21 and 22, by the shift amount ΔX = 5 mm of the assist spring 2007, the slide lengths of the curves 2 and 3 are reduced by 5 mm compared to the curve 1 in the manual slide region.
　また、リミッタ部材２０２１を備えた携帯機器の曲線３は、リミッタ部材を備えない携帯機器の曲線１、２に比べて、手動スライド領域から自動スライド領域に変わる前後で傾きが大きくなっているのが分かる。 Further, the curve 3 of the portable device provided with the limiter member 2021 has a larger inclination before and after the change from the manual slide region to the automatic slide region than the curves 1 and 2 of the portable device not provided with the limiter member. I understand.
　ここで、自動スライド領域に入っても、手動でないと自動スライドしない条件を、スライド荷重で５０ｇｆとすると、図２２に示すように、曲線１の手動スライド領域のスライド長さは３４ｍｍで、曲線３の手動スライド領域のスライド長さは２８ｍｍとなる。すなわち、手動スライド領域のスライド長さの低減量は６ｍｍとなる。よって、低減量の割合は、６／３４×１００＝１８％である。 Here, even if the automatic slide area is entered, if the slide load is 50 gf unless it is manually operated, the slide length of the manual slide area of curve 1 is 34 mm and curve 3 as shown in FIG. The slide length of the manual slide area is 28 mm. That is, the reduction amount of the slide length of the manual slide area is 6 mm. Therefore, the reduction ratio is 6/34 × 100 = 18%.
