Description

本発明は、開閉式の携帯機器に用いられるヒンジ機構に関する。 The present invention relates to a hinge mechanism used for an openable portable device.

従来、筐体の開閉に用いられるヒンジには、自動開閉感、クリック感等の所定の開閉感を持たせるために、ヒンジ軸は通常の軸ピンで構成し、このヒンジ軸の近傍に所定の制動機構を補助的に設けて上記機能を実現するもの、或いは軸部に用いられるヒンジ自体にカム等を用いた制動機構を設けて上記機能を実現するものがある。 Conventionally, in order to give a hinge used for opening and closing a casing to have a predetermined opening / closing feeling such as an automatic opening / closing feeling and a clicking feeling, the hinge shaft is configured by a normal shaft pin, and a predetermined opening is provided in the vicinity of the hinge axis. There are some which provide the above function by providing a braking mechanism as an auxiliary, and some which realize the above function by providing a braking mechanism using a cam or the like on the hinge itself used for the shaft portion.

例えば、特許文献１には、図１４（ａ）に示すように、回動軸ピン１８１により互いに回転自在に接続された第１の部材１８０および第２の部材１８２を備えた蝶番の開示があり、これは制動機構として、第１の部材１８０に一端を枢動自在に取り付け、他端を自由端とした第１のリンク１８４と、第２の部材１８２に一端を枢動自在に取り付け、他端を自由端とした第２のリンク１８６と、第１のリンク１８４の自由端と第２のリンク１８６の自由端との間に設けられたコイルスプリング１８８とを有する。 For example, Patent Document 1 discloses a hinge including a first member 180 and a second member 182 that are rotatably connected to each other by a rotating shaft pin 181 as shown in FIG. As a braking mechanism, one end is pivotally attached to the first member 180, the other end is a free end, and one end is pivotally attached to the second member 182. The second link 186 has a free end as an end, and a coil spring 188 provided between the free end of the first link 184 and the free end of the second link 186.

上記第１のリンク１８４の自由端には、止め突起部１８５が形成され、第２のリンク１８６には止め突起部１８７が形成され、これら第１のリンク１８４および第２のリンク１８６の周りにコイルスプリング１８８が装着され、このコイルスプリング１８８の各端部をそれぞれ上記突起部１８５，１８７に当接させている。 A stop protrusion 185 is formed at the free end of the first link 184, and a stop protrusion 187 is formed at the second link 186, around the first link 184 and the second link 186. A coil spring 188 is mounted, and each end of the coil spring 188 is brought into contact with the protrusions 185 and 187, respectively.

上記蝶番を用いた扉１９０は、図１４（ｂ）に示すように、当初１２０度開いた位置に固定保持され、この扉１９０を閉じる回動力を加えるとコイルスプリング１８８は圧縮され（この位置で回動力を除去すると、開き位置へと扉１９０を戻してしまう。）、さらに閉じる方向へ扉１９０に回動力を加え続けると、第１のリンク１８４と第２のリンク１８６との仮想ストロークは、最大となりカタストロフィー点を迎え、これを越えるとコイルスプリング１８８は伸長し始め、上記仮想ストロークは縮んで扉１９０は開く方向へ移動する。特許文献２，３にも、ヒンジ軸の近傍に制動機構を設けて所定の開閉感を持たせたヒンジ、開閉装置の記載がある。 As shown in FIG. 14B, the door 190 using the hinge is initially fixed and held at a position opened 120 degrees. When a turning force is applied to close the door 190, the coil spring 188 is compressed (at this position). If the turning force is removed, the door 190 is returned to the open position.) When the turning force is further applied to the door 190 in the closing direction, the virtual stroke between the first link 184 and the second link 186 is When the catastrophe point is reached and the maximum is reached, the coil spring 188 begins to expand, the virtual stroke contracts, and the door 190 moves in the opening direction. Patent Documents 2 and 3 also describe a hinge and an opening / closing device in which a braking mechanism is provided near the hinge shaft to give a predetermined opening / closing feeling.

一方、特許文献４には図１５（ａ）（ｂ）に示すように、二つ折りタイプの携帯用電話機１９２の送話部１９４と、受話部１９６の各対向端部に各々取付部を設け、両者を組み合せて小型ヒンジ装置１９８により、送話部と受話部とを互いに相対的に開閉可能に連結したものが開示されている。この小型ヒンジ装置１９８は内部に制動機構を有し、携帯電話機の送話部１９４と受話部１９６との相対的開成角度が２５°になると、固定カム部２００側へ摺動付勢されるカムスライダー２０２の凸部２０４は傾斜部を乗り越えて開かれ、４５°付近になるとコンプレッションスプリング２０６の弾力により自動的に１５０°まで開かれるものであり、受話部が所定の開位置（フリップポイント）を基準に、閉方向或いは開方向に回動付勢力が作用して自動的に開放、閉塞する。 On the other hand, in Patent Document 4, as shown in FIGS. 15 (a) and 15 (b), an attachment portion is provided at each of the opposite end portions of the transmitting portion 194 and the receiving portion 196 of the two-fold type portable telephone 192, A combination of the two and a small hinge device 198 connecting a transmitter and a receiver so that they can be opened and closed relative to each other is disclosed. This small hinge device 198 has a braking mechanism inside, and is a cam that is slidably biased toward the fixed cam portion 200 when the relative opening angle between the transmitting portion 194 and the receiving portion 196 of the mobile phone becomes 25 °. The convex portion 204 of the slider 202 is opened over the inclined portion, and when it reaches about 45 °, it is automatically opened to 150 ° by the elasticity of the compression spring 206, and the receiving portion has a predetermined open position (flip point). As a reference, a rotating biasing force acts in the closing direction or the opening direction to automatically open and close.

上記ヒンジ部材６の組み立てに際しては、ケース３２に収納したコイルバネ３０，３１の端部を第二カム部２８の端面部に当接させた状態で、第二カム部２８の両摺動凸部５２，５２をそれぞれケース３２の摺動凹部６８，６８に軸方向摺動自在に嵌合させる。一方、ケース３２の底部６２の外側にスライダー３４を介在させ、軸体３６の軸部８６を挿通孔から挿入して、コイルバネ３０，３１及び第二カム部２８の孔部５４を通過させる。 When assembling the hinge member 6, both sliding convex portions 52 of the second cam portion 28 are in a state where the end portions of the coil springs 30, 31 housed in the case 32 are in contact with the end surface portion of the second cam portion 28. , 52 are fitted in sliding recesses 68, 68 of the case 32 so as to be axially slidable. On the other hand, the slider 34 is interposed outside the bottom portion 62 of the case 32, and the shaft portion 86 of the shaft body 36 is inserted from the insertion hole so that the coil springs 30 and 31 and the hole portion 54 of the second cam portion 28 pass through.

ケース３２の摺動凹部６８，６８により、第二カム部２８はケース３２の軸方向に移動自在であり、この第二カム部２８に上記第一カム部２６を係合させる状態で、軸体３６の軸部７２に第一カム部２６を挿通する。最後に、軸体３６の軸部７２にワッシャー２４を嵌め、取付軸部７１をかしめてワッシャー２４を軸体３６の端部に係止させて取付け、ヒンジ部材６を組み立てる。 The second cam portion 28 is movable in the axial direction of the case 32 by the sliding recesses 68, 68 of the case 32, and the shaft body is in a state where the first cam portion 26 is engaged with the second cam portion 28.

Finally, the washer 24 is fitted to the shaft portion 72 of the shaft body 36, the mounting shaft portion 71 is caulked, the washer 24 is locked to the end portion of the shaft body 36, and the hinge member 6 is assembled.

上記ヒンジ部材６は、第二カム部２８がケース３２と嵌合して両者一体に回動し、第一カム部２６は第二カム部２８と係合しつつこの第二カム部２８とは相対的に回動する。一方、コイルバネ３０，３１により第一カム部２６と第二カム部２８とは常に両者は圧接する状態に付勢され、第一カム部２６と第二カム部２８との相対回動に伴い、第一カム部２６の係合凸部４２，４２が第二カム部２８の係合凹部５０，５０への侵入及び脱出を繰り返すカム機構を形成する。したがってヒンジ部材６は、上記カム機構を介して、ケース３２（第二カム部２８）に対して第一カム部２６が相対回動する。 The hinge member 6 has the second cam portion 28 fitted into the case 32 and rotates integrally therewith. The first cam portion 26 is engaged with the second cam portion 28 and the second cam portion 28 is It rotates relatively. On the other hand, the first cam portion 26 and the second cam portion 28 are always urged by the coil springs 30 and 31 so as to be in pressure contact with each other, and with the relative rotation of the first cam portion 26 and the second cam portion 28, The engaging convex portions 42 and 42 of the first cam portion 26 form a cam mechanism that repeatedly enters and exits the engaging concave portions 50 and 50 of the second cam portion 28. Accordingly, in the hinge member 6, the first cam portion 26 rotates relative to the case 32 (second cam portion 28) via the cam mechanism.

このヒンジ部材６は、回動の途中位置（フリップポイント：開角度の全開／２付近）において係合凸部４２は係合凹部５０の頂部に至り、ここから係合凸部４２が左右の各係合凹部５０を降下するに伴い、閉方向或いは開方向に付勢力が作用し自動的に開閉回動する。そして、コイルバネ３０，３１の付勢力により、係合凹部５０の谷底部へと吸込まれる作用が生じ、これにより所定のトルクが発生する。 In the hinge member 6, the engaging convex part 42 reaches the top of the engaging concave part 50 at the midway position of rotation (flip point: near the fully open / 2 of the opening angle), and the engaging convex part 42 extends to the left and right from here. As the engaging recess 50 is lowered, an urging force is applied in the closing direction or the opening direction to automatically open and close. The biasing force of the coil springs 30 and 31 causes an action of being sucked into the bottom of the engaging recess 50, thereby generating a predetermined torque.

上記ヒンジ部材６は、開く回動のときには、ヒンジ部材６の係合凸部４２は係合凹部５０を上昇し、その先端部が頂部に至り（フリップポイント）さらに、係合凸部４２は他方の係合凹部５０を降下するので、回動動作がフリップポイントを基準に閉方向或いは開方向へ自動回動するフリップ動作を行なう。 When the hinge member 6 is pivoted to open, the engaging convex portion 42 of the hinge member 6 rises in the engaging concave portion 50, the tip portion reaches the top (flip point), and the engaging convex portion 42 is on the other side. Since the engaging recess 50 is lowered, the flip operation is automatically flipped in the closing direction or the opening direction based on the flip point.

上記ヒンジ部材６の外形は、上述したようにケース３２と第一カム部２６とから形成され、軸に垂直な断面は全体的に小判形状である。またヒンジ部材６は、第二カム部２８がケース３２内に収納され、第一カム部２６はケース３２の開放口６４から突出した形態であるが、この第一カム部２６を軸方向に押圧することにより、コイルバネ３０，３１の圧縮に伴い第一カム部２６はケース３２内に没入収納が可能に形成されている。 The outer shape of the hinge member 6 is formed of the case 32 and the first cam portion 26 as described above, and the cross section perpendicular to the axis is an oval shape as a whole. In addition, the hinge member 6 is configured such that the second cam portion 28 is housed in the case 32 and the first cam portion 26 protrudes from the opening 64 of the case 32, and the first cam portion 26 is pressed in the axial direction.

The pin 12 is inserted into the portion 103, and the fastening portion 114 at the tip of the pin 12 is screwed and fixed into the pin hole 162 provided in the connecting portion 160 of the opening / closing body substrate 142 of the portable device. In this state, the arm member 10 is swingably connected to the connecting portion 160 of the opening / closing body substrate 142 via the pin 12.

なお、上記ピン１２は、ピン孔１６２に螺入固定する形態であるが、リベット形式でピン１２先をピン孔１６２に固定する形態であってもよい。携帯機器の開閉部の他方側にも、上記と同様な形態でヒンジ機構（上記ヒンジ機構２とは対称形状）を取り付ける。 In addition, although the said pin 12 is the form fixed by screwing in the pin hole 162, the form which fixes the pin 12 tip to the pin hole 162 by a rivet form may be sufficient. A hinge mechanism (symmetrical shape with respect to the hinge mechanism 2) is attached to the other side of the opening / closing part of the portable device in the same manner as described above.

また、上記ヒンジ機構２を携帯機器の開閉部の一方側にのみ用い、他方側についてはダミーのヒンジ部材１３２を用いたヒンジ機構を取り付けることとしてもよい。このとき、ヒンジ部材１３２の突起１３５を本体基板１４０の保持孔１５４に突入させる一方、突軸部１３６を本体基板１４０に取り付けたホルダー１４の孔部１２９に突入させ、ダミーのヒンジ部材１３２を回動自在に保持する。さらに、上記アーム部材１０のアーム部１００を上記ヒンジ部材１３２の摺動孔１３８に差し込み、併せてアーム部材１０の孔部１０３に上記ピン１２を挿入し、ピン１２先を開閉体基板１４２のピン孔１６２に固定する。このダミーのヒンジ部材１３２により、ヒンジ機構２との関係でバランスがとれた開閉が行える。 Further, the hinge mechanism 2 may be used only on one side of the opening / closing part of the portable device, and a hinge mechanism using a dummy hinge member 132 may be attached on the other side.

Further, the arm portion 100 of the arm member 10 is inserted into the sliding hole 138 of the hinge member 132, and the pin 12 is inserted into the hole portion 103 of the arm member 10. Fix to the hole 162. The dummy hinge member 132 can be opened and closed in a balanced manner in relation to the hinge mechanism 2.

さて、上記開閉体基板１４２の開閉は上記ヒンジ軸１４３を回動中心として行われるが、この回動中心と、本体基板１４０に固定されたヒンジ部材６の回動中心とは、所定間隔の隔たりがある平行線上にあり中心位置が異なる。このため、上記ヒンジ軸１４３を回動中心とした開閉体基板１４２の開閉にともない、ヒンジ部材６による回動中心と開閉体基板１４２の連結部１６０との距離は変動する。そこで、上記距離が変動する機構を、上記連結部１６０で軸支されたアーム部材１０がジョイント８の摺動孔９６を摺動させることで実現している。そして、開閉体基板１４２は、上記ヒンジ軸１４３を回動軸とした回動機構による回動動作に加えて、上記ヒンジ機構２の制動特性によるフリップ動作を伴った開閉を行う。 The opening / closing body 142 is opened and closed with the hinge shaft 143 as a rotation center. The rotation center and the rotation center of the hinge member 6 fixed to the main body substrate 140 are separated by a predetermined distance. Is on a parallel line and the center position is different. For this reason, the distance between the rotation center of the hinge member 6 and the connecting portion 160 of the opening / closing body substrate 142 varies with the opening / closing of the opening / closing body substrate 142 with the hinge shaft 143 as the rotation center. Therefore, the mechanism in which the distance fluctuates is realized by the arm member 10 pivotally supported by the connecting portion 160 sliding the sliding hole 96 of the joint 8. The opening / closing body substrate 142 opens and closes with a flip operation based on a braking characteristic of the hinge mechanism 2 in addition to a rotation operation by a rotation mechanism using the hinge shaft 143 as a rotation axis.

図１１は、上記回動機構と制動機構を装着した携帯機器の側部断面を示したものである。
この携帯機器は、上記ヒンジ機構２の本体（ヒンジホルダー４、ヒンジ部材６及びジョイント８）を取り付けた本体基板１４０に本体筐体１７０を装着し、上記開閉体基板１４２に開閉筐体１７２を装着して形成される。このためヒンジ機構２は、アーム部材１０を残して全て本体筐体１７０内に収納される。また、上記開閉筐体１７２でアーム部材１０を覆うことで、外観上アーム部材１０もほとんど目立たなくなる。 FIG. 11 shows a side cross-section of a portable device equipped with the turning mechanism and the braking mechanism.
In this portable device, a main body case 170 is attached to a main body substrate 140 to which the main body (hinge holder 4, hinge member 6 and joint 8) of the hinge mechanism 2 is attached, and an open / close case 172 is attached to the open / close body substrate 142. Formed. For this reason, the hinge mechanism 2 is entirely housed in the main body casing 170 with the arm member 10 being left. Further, by covering the arm member 10 with the opening / closing casing 172, the arm member 10 is hardly noticeable in appearance.

図１２は、上記携帯機器の本体筐体１７０に対する開閉筐体１７２の各開角度における状態、及びヒンジ機構２のジョイント８の回動位置及びアーム部材１０の移動位置の形態を示すものである。ここで、上記ヒンジ軸１４３を回動中心とした本体筐体１７０に対する開閉筐体１７２の開角度は、図１２（ａ）は０°、（ｂ）は３０°、（ｃ）は６０°、（ｄ）は９０°、（ｅ）は１２０°、（ｆ）は１４０°、（ｇ）は１６５°である。 FIG. 12 shows the state of each opening angle of the open / close housing 172 with respect to the main body housing 170 of the portable device, and the form of the rotation position of the joint 8 and the movement position of the arm member 10 of the hinge mechanism 2. Here, the opening angle of the open / close housing 172 with respect to the main body housing 170 around the hinge shaft 143 is 0 ° in FIG. 12, (b) is 30 °, (c) is 60 °, (D) is 90 °, (e) is 120 °, (f) is 140 °, and (g) is 165 °.

開閉筐体１７２の開角度が０°のときは、アーム部材１０は、ジョイント８の摺動孔９６から少し突き抜けた状態であるが、開角度が３０°、６０°、９０°と開くにつれて、アーム部材１０は時計方向に角度が変化しつつ上方に移動し、またアーム部材１０の移動に伴ってジョイント８も回動する。このように、アーム部材１０の軸受部１０４はヒンジ部材６の回動中心から離れる方向に向かうため、アーム部材１０のアーム部１００はジョイント８の摺動孔９６を摺動しつつ上方に移動する。さらに、開閉筐体１７２の開角度が１２０°近傍に至ると、アーム部材１０の軸受部１０４はヒンジ部材６の回動中心から最も遠くに位置する。 When the opening angle of the open / close housing 172 is 0 °, the arm member 10 is slightly protruded from the sliding hole 96 of the joint 8, but as the opening angle opens to 30 °, 60 °, and 90 °, The arm member 10 moves upward while changing the angle in the clockwise direction, and the joint 8 also rotates as the arm member 10 moves. Thus, since the bearing portion 104 of the arm member 10 moves away from the rotation center of the hinge member 6, the arm portion 100 of the arm member 10 moves upward while sliding on the sliding hole 96 of the joint 8. . Furthermore, when the opening angle of the open / close housing 172 reaches around 120 °, the bearing portion 104 of the arm member 10 is located farthest from the rotation center of the hinge member 6.

さらに開閉筐体１７２の開角度が１４０°、１６５°に開くと、アーム部材１０の角度は本体筐体の向きに近くなるとともに、アーム部材１０の軸受部１０４はヒンジ部材６の回動中心に近づく方向に移動する。そして、開閉筐体１７２の開角度が１６５°まで開くと、本体筐体１７０の端部と開閉筐体１７２の端部同士が当接するストッパー機構により、開閉筐体１７２の開動作は停止する。 Further, when the opening angle of the opening / closing housing 172 is opened to 140 ° and 165 °, the angle of the arm member 10 is close to the direction of the main body housing, and the bearing portion 104 of the arm member 10 is at the center of rotation of the hinge member 6. Move in the direction of approach. When the opening angle of the opening / closing casing 172 is opened to 165 °, the opening operation of the opening / closing casing 172 is stopped by the stopper mechanism in which the end of the main body casing 170 and the ends of the opening / closing casing 172 contact each other.

一方、ヒンジ機構２に内蔵されるヒンジ部材６は、開閉筐体１７２の開角度が９０°近傍にフリップポイントが設けられているため、開閉筐体１７２は、開閉動作がフリップポイントを基準に閉方向或いは開方向へ自動回動するフリップ動作を行なう。このフリップ動作により、携帯機器の操作者は、携帯機器の開閉時において、良好なフリップ感、吸い込み感などの開閉感が得られる。また、ヒンジ部材６は、開閉筐体の閉塞時及び開放時には強い吸込みのトルクが作用し、開閉筐体を本体筐体に強く押圧してがたつきの無い確実な保持がなされる。 On the other hand, the hinge member 6 incorporated in the hinge mechanism 2 is provided with a flip point near the opening angle of the open / close housing 172 of 90 °. Therefore, the open / close housing 172 closes based on the flip point. A flip operation that automatically rotates in the direction or the opening direction is performed. By this flip operation, the operator of the portable device can obtain a good feeling of opening and closing such as a feeling of flipping and sucking when the portable device is opened and closed. Further, the hinge member 6 is subjected to a strong suction torque when the open / close housing is closed and opened, so that the open / close housing is strongly pressed against the main body housing and is reliably held without rattling.

従って、上記実施の形態に係るヒンジ機構２及びこのヒンジ機構２を用いた携帯機器によれば、アーム部材を残してヒンジの本体を携帯機器の本体筐体内に収納するため、本体筐体と開閉体筐体との連結部は、軸ピン等を用いて簡単に構成し得るため、本体筐体と開閉体筐体との開閉部分が簡素に形成されて美観に優れる。また、ヒンジ部材の交換が容易に行えることから、各ヒンジの制動特性に応じた開閉感、例えば開閉時のクリック感、フリップ感（吸い込み感）、或いはトルク感など、所望する開閉感が自由に得られ汎用性に富むという効果がある。 Therefore, according to the hinge mechanism 2 and the portable device using the hinge mechanism 2 according to the above-described embodiment, the hinge main body is housed in the main body housing of the portable device, leaving the arm member. Since the connecting portion with the body casing can be easily configured using a shaft pin or the like, the opening / closing portion between the main body casing and the opening / closing body casing is simply formed, and the appearance is excellent. In addition, since the hinge members can be easily replaced, the desired opening and closing feeling such as an opening and closing feeling corresponding to the braking characteristic of each hinge, for example, a clicking feeling when opening and closing, a flip feeling (suction feeling), or a torque feeling can be freely set. Obtained and versatile.

A bearing 230 having a circular hole 228 is formed in the orthogonal direction. As shown in FIG. 13 (c), the base 212 of the joint 210 is fitted into the left and right arms 225 of the frame-shaped base 224 of the arm member 222 with some play, and the sliding of the arms 225 is performed. The surfaces 226 and 226 are in contact with the sliding surfaces 218 and 218 of the joint 210 and freely slide in the frame-like base 224 to reciprocate.

上記ジョイント２１０及びアーム部材２２２の取り付け形態は、上記ジョイント８及びアーム部材１０の取り付け形態とそれぞれ同様であり、アーム部材２２２の枠状基部２２４にジョイント２１０の基部２１２を嵌め入れた状態で、上記ヒンジ部材６と嵌合させたジョイント２１０の突軸部２１６を上記本体基板１４０に固定した上記ホルダー１４の孔部１２９に突入させる一方、アーム部材２２２の孔部２２８に上記ピン１２を用いてアーム部材２２２を開閉体基板１４２の連結部１６０に揺動可能に連結する。このジョイント２１０及びアーム部材２２２を用いた形態においても、本体筐体と開閉体筐体との開閉部分が簡素に形成されて美観に優れる。 The attachment form of the joint 210 and the arm member 222 is the same as the attachment form of the joint 8 and the arm member 10, respectively, and the base 212 of the joint 210 is fitted into the frame-like base 224 of the arm member 222.
