Description

本発明は、折り畳み式携帯電話機等に用いられるヒンジ装置に関する。   The present invention relates to a hinge device used for a folding cellular phone or the like.

上述のような従来のヒンジ装置は、例えば、特開２００３−９０３２７号公報にも開示されるように、折り畳み式携帯電話の本体部に配設される筒状体である第１ヒンジ部材と、折り畳み式携帯電話の蓋体部に配設される第２ヒンジ部材（カシメ部材）と、第１ヒンジ部材と第２ヒンジ部材とを枢結する軸部材とを主体に構成される。樹脂材料を用いて一体成型される第１ヒンジ部材（筒状体）には、その底部に開口した軸孔からフランジ状の軸頭部を有する軸部材が挿着され、軸部材の先端部が第１ヒンジ部材の開口部より突き出るようになっている。第１ヒンジ部材の内部には、その開口部より軸部材に装着するように圧縮コイルバネが挿入され、この圧縮コイルバネに隣接して軸部材に中心の軸孔を通して位置決め部材が挿入される。位置決め部材は金属材から成形され、表面側に一対のほぼ半球状の凸部が設けられており、この凸部の背後に形成された脚部を第１ヒンジ部材に形成された切欠部に嵌合させることで、位置決め部材が第１ヒンジ部材に対し回転不能にセットされる。   The conventional hinge device as described above includes, for example, a first hinge member that is a cylindrical body disposed in a main body of a foldable mobile phone, as disclosed in JP-A-2003-90327. It is mainly composed of a second hinge member (caulking member) disposed on the lid portion of the folding cellular phone and a shaft member that pivots the first hinge member and the second hinge member. A shaft member having a flange-shaped shaft head is inserted into the first hinge member (cylindrical body) integrally molded using a resin material from the shaft hole opened at the bottom thereof, and the tip portion of the shaft member is It protrudes from the opening of the first hinge member. A compression coil spring is inserted into the first hinge member so as to be attached to the shaft member through the opening, and a positioning member is inserted into the shaft member through a central shaft hole adjacent to the compression coil spring. The positioning member is formed of a metal material, and a pair of substantially hemispherical convex portions are provided on the surface side, and the leg portion formed behind the convex portion is fitted into the notch portion formed in the first hinge member. By combining, the positioning member is set so as not to rotate with respect to the first hinge member.

また、位置決め部材に隣接して金属材からなる被位置決め部材がその中心の角孔を軸部材先端部の角軸に通して挿入され、この被位置決め部材の裏面には位置決め部材の凸部と係合する円弧状の凹部が形成されている。そして、被位置決め部材に隣接して第２ヒンジ部材（カシメ部材）がその中心の角孔を軸部材先端部の角軸に通して挿入され、第２ヒンジ部材から突出する角軸の先端部を加熱等することでカシメ固定される。第２ヒンジ部材には、弾性機能を有するフック部が一体的に形成されている。なお、角軸のカシメ固定の際、被位置決め部材及び第２ヒンジ部材を圧縮コイルバネ側に加圧し、つまり、圧縮コイルバネを圧縮状態にしてカシメ固定される。すなわち、圧縮コイルバネのバネ復元力により位置決め部材の凸部と、被位置決め部材の凹部との係合状態が維持されロックされた状態となる。   Further, a member to be positioned made of a metal material is inserted adjacent to the positioning member through a square hole at the center thereof through the square shaft at the tip of the shaft member, and the rear surface of the member to be positioned is engaged with the convex portion of the positioning member. An arcuate recess is formed. Then, a second hinge member (caulking member) is inserted adjacent to the positioned member through the central angular hole of the shaft member tip, and the tip of the angular shaft protruding from the second hinge member is inserted. It is fixed by caulking by heating. A hook portion having an elastic function is integrally formed on the second hinge member. It should be noted that at the time of caulking and fixing the angular axis, the positioned member and the second hinge member are pressed against the compression coil spring, that is, the compression coil spring is compressed and fixed. That is, the engagement state between the convex portion of the positioning member and the concave portion of the positioned member is maintained and locked by the spring restoring force of the compression coil spring.

上述したヒンジ装置を折り畳み式携帯電話に組み込むには、第１ヒンジ部材を本体部の第１ヒンジ外筒に圧入等により固定する。この際、第１ヒンジ部材の外周面に軸方向に形成された凹溝が第１ヒンジ外筒の内壁面に係合し第１ヒンジ部材が本体部に対して回転不能にされる。一方、第２ヒンジ部材は被位置決め部材と共に蓋体部の第２ヒンジ外筒に挿着され、フック部により蓋体部に対し固定保持されるとともに、第２ヒンジ部材および被位置決め部材の外周面に軸方向に形成された凹溝が第２ヒンジ外筒の内壁面に係合し蓋体部に対して回転不能にされる。   In order to incorporate the hinge device described above into a foldable mobile phone, the first hinge member is fixed to the first hinge outer cylinder of the main body by press-fitting or the like. At this time, a concave groove formed in the axial direction on the outer peripheral surface of the first hinge member engages with the inner wall surface of the first hinge outer cylinder so that the first hinge member cannot be rotated with respect to the main body. On the other hand, the second hinge member is inserted into the second hinge outer cylinder of the lid portion together with the positioned member, and is fixedly held to the lid portion by the hook portion, and the outer peripheral surfaces of the second hinge member and the positioned member A concave groove formed in the axial direction engages with the inner wall surface of the second hinge outer cylinder so that it cannot be rotated with respect to the lid portion.

このように構成されるヒンジ装置において、折り畳み式携帯電話の蓋体部が本体部に対し折り畳まれて閉止した状態では、位置決め部材の凸部と被位置決め部材の凹部とが係合状態となり、蓋体部が閉止位置にロックされる。ここで、蓋体部が開放位置へ向けて開放動作されると、第２ヒンジ部材および被位置決め部材が第１ヒンジ部材および位置決め部材に対して相対回転するとともに、位置決め部材の凸部と被位置決め部材の凹部との係合状態が圧縮コイルバネの付勢力に抗して解除され、蓋体部が閉止位置から所定角度（例えば、本体部に対して１６５°）だけ相対回転したときに、本体部および蓋体部にそれぞれ設けられた当接部が互いに当接することによって蓋体部の本体部に対する相対回転が規制され、蓋体部が本体部に対し開放位置で開放した状態となる。
特開２００３−９０３２７号公報 特開２００３−１８４８５９号公報 In the hinge device configured as described above, when the lid portion of the foldable mobile phone is folded and closed with respect to the main body portion, the convex portion of the positioning member and the concave portion of the positioned member are engaged, and the lid The body is locked in the closed position. Here, when the lid portion is opened toward the open position, the second hinge member and the positioned member rotate relative to the first hinge member and the positioning member, and the convex portion of the positioning member and the positioned member are positioned. When the engagement state of the member with the concave portion is released against the urging force of the compression coil spring, and the lid body portion rotates relative to the closing position by a predetermined angle (for example, 165 ° with respect to the main body portion), the main body portion The abutment portions respectively provided on the lid body portion abut against each other, so that the relative rotation of the lid body portion with respect to the main body portion is restricted, and the lid body portion is opened at the open position with respect to the main body portion.

しかしながら、位置決め部材および被位置決め部材は、金属材からプレス加工等により成形されていたため、加工工数および部品点数が増加し製造コスト上昇の一因となっていた。   However, since the positioning member and the member to be positioned are formed from a metal material by pressing or the like, the number of processing steps and the number of parts increase, which contributes to an increase in manufacturing cost.

本発明は、このような問題に鑑みてなされたものであり、ヒンジ装置の製造コスト低減を図ることを目的とする。   The present invention has been made in view of such a problem, and an object thereof is to reduce the manufacturing cost of the hinge device.

このような目的達成のため、本発明に係るヒンジ装置は、一端側が開口した有底円筒状の第１ヒンジ部材と、第１ヒンジ部材の一端側に対向して設けられ、中心軸と略直角な方向に延びて形成された第１ピン孔を有する第２ヒンジ部材と、第１ヒンジ部材の一端側に第１ヒンジ部材の中心軸方向へスライド移動可能に配設され、第２ヒンジ部材と対向する面に半球面状の一対の凹部が中心軸対称に形成された位置決め部材と、先端部に中心軸と略直角な方向に延びて形成された第２ピン孔と、基端部に第１ヒンジ部材の底部外側と摺接するように形成された軸頭部とを有し、軸頭部が第１ヒンジ部材の底部外側と摺接する状態で第１ヒンジ部材と第２ヒンジ部材とを枢結するように構成された軸部材と、第２ヒンジ部材の位置決め部材と対向する面に取り付けられ、一対の凹部にそれぞれ係合することで第２ヒンジ部材の第１ヒンジ部材および位置決め部材に対する相対回転を規制する先端半球形の一対の係合ピンと、第１ヒンジ部材の内部に配設され、位置決め部材を係合ピンに向けて付勢する付勢バネと、軸部材により第１ヒンジ部材と第２ヒンジ部材とが枢結された状態で第１ピン孔および第２ピン孔と嵌合し、第２ヒンジ部材の軸部材に対する相対移動を規制するストッパーピンとを備え、第２ヒンジ部材を第１ヒンジ部材および位置決め部材に対して相対回転させることにより、係合ピンと凹部との係合状態が付勢バネの付勢力に抗して解除されるように構成される。   In order to achieve such an object, a hinge device according to the present invention is provided with a bottomed cylindrical first hinge member having one end opened, and opposed to one end of the first hinge member, and substantially perpendicular to the central axis. A second hinge member having a first pin hole formed extending in any direction, and disposed on one end side of the first hinge member so as to be slidable in the direction of the central axis of the first hinge member, A positioning member in which a pair of hemispherical concave portions are formed symmetrically with respect to the central axis on opposite surfaces, a second pin hole formed at the distal end portion extending in a direction substantially perpendicular to the central axis, and a second pin hole formed at the proximal end portion. A shaft head formed so as to be in sliding contact with the outside of the bottom portion of the first hinge member, and pivoting the first hinge member and the second hinge member in a state where the shaft head is in sliding contact with the outside of the bottom portion of the first hinge member. Opposing the shaft member configured to tie and the positioning member of the second hinge member A pair of hemispherical tip pins that restrict relative rotation of the second hinge member with respect to the first hinge member and the positioning member by engaging with a pair of recesses, and the interior of the first hinge member And a biasing spring that biases the positioning member toward the engaging pin, and a first pin hole and a second pin in a state in which the first hinge member and the second hinge member are pivotally connected by the shaft member. A stopper pin that fits into the hole and restricts relative movement of the second hinge member with respect to the shaft member, and rotates the second hinge member relative to the first hinge member and the positioning member, whereby the engaging pin and the recess The engagement state is configured to be released against the biasing force of the biasing spring.

また、上述の発明において、第２ヒンジ部材が樹脂材料を用いて一体成型されることが好ましい。   Moreover, in the above-mentioned invention, it is preferable that the second hinge member is integrally molded using a resin material.

本発明によれば、凹部を有する位置決め部材が第１ヒンジ部材に配設されるとともに、位置決め部材の凹部に係合可能な係合ピンが第２ヒンジ部材に取り付けられているため、係合ピンを保持する被位置決め部材を別途設ける必要がないことから、ヒンジ装置の加工工数および部品点数が低減し、ヒンジ装置の製造コストを低減させることができる。   According to the present invention, the positioning member having the recess is disposed on the first hinge member, and the engagement pin that can be engaged with the recess of the positioning member is attached to the second hinge member. Since there is no need to separately provide a positioned member for holding the hinge, the number of processing steps and the number of parts of the hinge device can be reduced, and the manufacturing cost of the hinge device can be reduced.

また、第２ヒンジ部材が樹脂材料を用いて一体成型されることで、ヒンジ装置をより軽量化することができる。   Moreover, since the second hinge member is integrally molded using a resin material, the hinge device can be further reduced in weight.

The second hinge member 50 and the shaft member 60 that pivotally connects the first hinge member 40 and the second hinge member 50 are mainly configured. As shown in FIGS. 2 and 3, the first hinge member 40 is integrally formed into a bottomed cylindrical shape having one end opened using a resin material. A first shaft hole 41 is formed in the center of the bottom of the first hinge member 40 so that the shaft member 60 can be fitted therethrough.

図３に示すように、第１ヒンジ部材４０の側部には第１凹溝４２が中心軸方向へ延びて形成されており、第１ヒンジ外筒部２５の内壁部に形成された反転形状の係合凸部（図示せず）と係合することで、第１ヒンジ部材４０の第１ヒンジ外筒部２５（すなわち、本体部２）に対する相対回転が規制されるようになっている。第１ヒンジ部材４０の一端側には切欠部４３が形成されており、位置決め部材７０が取り付けられるようになっている。また、第１ヒンジ部材４０の内部には付勢バネ８０が収容されている。   As shown in FIG. 3, a first concave groove 42 is formed on the side portion of the first hinge member 40 so as to extend in the central axis direction, and the inverted shape formed on the inner wall portion of the first hinge outer cylinder portion 25. By engaging with the engaging projection (not shown), the relative rotation of the first hinge member 40 with respect to the first hinge outer cylinder 25 (that is, the main body 2) is restricted. A notch 43 is formed on one end side of the first hinge member 40 so that the positioning member 70 can be attached. A biasing spring 80 is accommodated in the first hinge member 40.

位置決め部材７０は、図２および図３に示すように、金属材からプレス加工等により図示する形状に成形され、第２ヒンジ部材５０と対向する面に半球面状の一対の凹部７１が中心軸対称に形成される。位置決め部材７０の側部には、凹部７１と位置整合して脚部７２が形成されており、この脚部７２を第１ヒンジ部材４０の切欠部４３に嵌合させることで、位置決め部材７０が第１ヒンジ部材４０の一端側に第１ヒンジ部材４０の中心軸方向へスライド移動可能に取り付けられる。また、位置決め部材７０の中央には第３軸孔７３が形成されており、軸部材６０が通過して嵌合するようになっている。   As shown in FIGS. 2 and 3, the positioning member 70 is molded from a metal material into a shape shown in the drawing by pressing or the like, and a pair of hemispherical concave portions 71 are formed on the surface facing the second hinge member 50 as a central axis. It is formed symmetrically. A leg portion 72 is formed on the side portion of the positioning member 70 so as to be aligned with the concave portion 71. By fitting the leg portion 72 into the cutout portion 43 of the first hinge member 40, the positioning member 70 is moved. The first hinge member 40 is attached to one end side of the first hinge member 40 so as to be slidable in the central axis direction of the first hinge member 40. A third shaft hole 73 is formed at the center of the positioning member 70 so that the shaft member 60 can be fitted therethrough.

付勢バネ８０は、金属線材から形成される圧縮コイルバネであり、軸部材６０を挿通させた状態で第１ヒンジ部材４０の内部に収容され、位置決め部材７０が第１ヒンジ部材４０の一端側に取り付けられた状態で、位置決め部材７０に対し第１ヒンジ部材４０の一端側に向かう方向へ付勢力を与えるようになっている。   The biasing spring 80 is a compression coil spring formed of a metal wire, and is housed inside the first hinge member 40 with the shaft member 60 inserted, and the positioning member 70 is located on one end side of the first hinge member 40. In the attached state, a biasing force is applied to the positioning member 70 in a direction toward one end side of the first hinge member 40.

第２ヒンジ部材５０は、図２および図３に示すように、樹脂材料を用いて円柱状に一体成型され、第１ヒンジ部材４０の開口側（一端側）に対向して設けられる。図２に示すように、第２ヒンジ部材５０の中央には第２軸孔５１が形成されており、軸部材６０の先端部（一端側）が嵌合するようになっている。また、図３に示すように、第１ピン孔５２が第２軸孔５１に対し略直角な方向に延びて形成されており、詳細は後述するストッパーピン６５が嵌合するようになっている。   As shown in FIGS. 2 and 3, the second hinge member 50 is integrally formed in a cylindrical shape using a resin material, and is provided to face the opening side (one end side) of the first hinge member 40. As shown in FIG. 2, a second shaft hole 51 is formed at the center of the second hinge member 50, and the tip end portion (one end side) of the shaft member 60 is fitted. Further, as shown in FIG. 3, the first pin hole 52 is formed extending in a direction substantially perpendicular to the second shaft hole 51, and a stopper pin 65, which will be described in detail later, is fitted therein. .

第２ヒンジ部材５０の一端には弾性機能を有するフック部５３が一体的に形成されており、第２ヒンジ外筒部３５の内部に形成された係止部（図示せず）に係止することで、第２ヒンジ部材５０が第２ヒンジ外筒部３５（すなわち、蓋体部３）に固定保持されるようになっている。また、第２ヒンジ部材５０の側部には第２凹溝５４が中心軸方向へ延びて形成されており、第２ヒンジ外筒部３５の内部に形成された反転形状の係合凸部（図示せず）と係合することで、第２ヒンジ部材５０の第２ヒンジ外筒部３５（すなわち、蓋体部３）に対する相対回転が規制されるようになっている。   A hook portion 53 having an elastic function is integrally formed at one end of the second hinge member 50 and is locked to a locking portion (not shown) formed inside the second hinge outer cylinder portion 35. Thus, the second hinge member 50 is fixedly held by the second hinge outer cylinder portion 35 (that is, the lid portion 3). Further, a second concave groove 54 is formed on the side portion of the second hinge member 50 so as to extend in the central axis direction, and an inverted engaging convex portion (inside the second hinge outer cylinder portion 35) ( By engaging with the second hinge member 50, the relative rotation of the second hinge member 50 with respect to the second hinge outer cylinder portion 35 (that is, the lid portion 3) is restricted.

さて、第２ヒンジ部材５０の位置決め部材７０と対向する面には、位置決め部材７０の凹部７１にそれぞれ係合可能な一対の係合ピン５５が取り付けられている。係合ピン５５は、先端半球形の丸棒状に形成され、第２ヒンジ部材５０の位置決め部材７０と対向する面に形成されたピン取付孔５６にそれぞれ圧入取付される。そして、一対の係合ピン５５が一対の凹部７１にそれぞれ係合することで、第２ヒンジ部材５０の第１ヒンジ部材４０および位置決め部材７０に対する相対回転が規制されるようになっている。   Now, a pair of engaging pins 55 that can engage with the recesses 71 of the positioning member 70 are attached to the surface of the second hinge member 50 that faces the positioning member 70. The engaging pins 55 are formed in a hemispherical round bar shape and are press-fitted and attached to pin attachment holes 56 formed on the surface of the second hinge member 50 facing the positioning member 70. The pair of engaging pins 55 are engaged with the pair of recesses 71, respectively, so that the relative rotation of the second hinge member 50 with respect to the first hinge member 40 and the positioning member 70 is restricted.

これにより、凹部７１を有する位置決め部材７０が第１ヒンジ部材４０に配設されるとともに、位置決め部材７０の凹部７１に係合可能な係合ピン５５が第２ヒンジ部材５０に取り付けられているため、係合ピンを保持する被位置決め部材を別途設ける必要がないことから、ヒンジ装置の加工工数および部品点数が低減し、ヒンジ装置の製造コストを低減させることができる。なお、係合ピン５５は、第２ヒンジ部材５０のピン取付孔５６に圧入取付されているが、これに限られるものではなく、インサート成形により第２ヒンジ部材に取り付けるようにしてもよい。   Accordingly, the positioning member 70 having the recess 71 is disposed on the first hinge member 40, and the engagement pin 55 that can be engaged with the recess 71 of the positioning member 70 is attached to the second hinge member 50. Since there is no need to separately provide a positioned member for holding the engagement pin, the number of processing steps and the number of parts of the hinge device can be reduced, and the manufacturing cost of the hinge device can be reduced. The engagement pin 55 is press-fitted and attached to the pin attachment hole 56 of the second hinge member 50, but is not limited thereto, and may be attached to the second hinge member by insert molding.

軸部材６０は、金属材からピン形状に形成され、第１ヒンジ部材４０の底部外側から第１ヒンジ部材４０の第１軸孔４１および位置決め部材７０の第３軸孔７３を貫通して第２ヒンジ部材５０の第２軸孔５１まで延びている。軸部材６０の基端部には、フランジ状の軸頭部６１が形成されており、第１ヒンジ部材４０の底部外側と摺接して軸部材６０の第１ヒンジ部材４０に対する開口側（一端側）への相対移動が規制されるようになっている。軸部材６０の先端部には、軸部材６０の中心軸と略直角な方向に延びて第２ピン孔６２が形成されており、ストッパーピン６５が嵌合するようになっている。   The shaft member 60 is formed in a pin shape from a metal material, and passes through the first shaft hole 41 of the first hinge member 40 and the third shaft hole 73 of the positioning member 70 from the bottom outer side of the first hinge member 40 to the second. The hinge member 50 extends to the second shaft hole 51. A flange-like shaft head 61 is formed at the base end portion of the shaft member 60, and is in sliding contact with the outside of the bottom portion of the first hinge member 40. One end side of the shaft member 60 with respect to the first hinge member 40 (one end side). ) Relative movement is restricted. A second pin hole 62 is formed at a distal end portion of the shaft member 60 so as to extend in a direction substantially perpendicular to the central axis of the shaft member 60, and a stopper pin 65 is fitted therein.

ストッパーピン６５は、金属材から棒状に形成され、第２ヒンジ部材５０の第１ピン孔５２および軸部材６０の第２ピン孔６２と嵌合することで、第２ヒンジ部材５０の軸部材６０に対する相対移動が規制されるようになっている。これにより、カシメ加工等を用いることなく容易にヒンジ装置４を組み立てることができる。   The stopper pin 65 is formed in a rod shape from a metal material, and is fitted to the first pin hole 52 of the second hinge member 50 and the second pin hole 62 of the shaft member 60, thereby the shaft member 60 of the second hinge member 50. The relative movement with respect to is regulated. Thereby, the hinge apparatus 4 can be assembled easily, without using a crimping process etc.

以上のように構成されるヒンジ装置４を組み立てるには、まず、軸部材６０を第１ヒンジ部材４０の第１軸孔４１に挿通して嵌合させる。次に、軸部材６０を挿通させるようにして付勢バネ８０を第１ヒンジ部材４０の内部に開口側（一端側）から挿入する。続いて、軸部材６０を位置決め部材７０の第３軸孔７３に挿通して嵌合させるとともに、位置決め部材７０の脚部７２を第１ヒンジ部材４０の切欠部４３に嵌合させることで、位置決め部材７０を付勢バネ８０に隣接させた状態で第１ヒンジ部材４０の一端側に第１ヒンジ部材４０の中心軸方向へスライド移動可能に取り付ける。なお、位置決め部材７０の凹部７１は、第１ヒンジ部材４０の一端側に向けられる。   In order to assemble the hinge device 4 configured as described above, first, the shaft member 60 is inserted into and fitted into the first shaft hole 41 of the first hinge member 40. Next, the urging spring 80 is inserted into the first hinge member 40 from the opening side (one end side) so that the shaft member 60 is inserted. Subsequently, the shaft member 60 is inserted into the third shaft hole 73 of the positioning member 70 and fitted therein, and the leg portion 72 of the positioning member 70 is fitted into the cutout portion 43 of the first hinge member 40, thereby positioning. The member 70 is attached to one end side of the first hinge member 40 so as to be slidable in the central axis direction of the first hinge member 40 in a state where the member 70 is adjacent to the biasing spring 80. The recess 71 of the positioning member 70 is directed to one end side of the first hinge member 40.

そして、軸部材６０の先端部を第２ヒンジ部材５０の第２軸孔５１に挿入して嵌合させ、ストッパーピン６５を第２ヒンジ部材５０の第１ピン孔５２および軸部材６０の第２ピン孔６２と嵌合させることで第２ヒンジ部材５０が固定される。なおこのとき、第２ヒンジ部材５０の係合ピン５５に位置決め部材７０を押圧させ、付勢バネ８０を圧縮状態にしてストッパーピン６５を第１ピン孔５２および第２ピン孔６２と嵌合させる。そのため、位置決め部材７０が付勢バネ８０の付勢力を受けて係合ピン５５を常に押圧する状態となり、付勢バネ８０の付勢力を利用して第２ヒンジ部材５０の係合ピン５５と位置決め部材７０の凹部７１との係合状態を維持してロック可能な状態となる。   And the front-end | tip part of the shaft member 60 is inserted and fitted in the 2nd shaft hole 51 of the 2nd hinge member 50, and the stopper pin 65 is made into the 1st pin hole 52 of the 2nd hinge member 50, and the 2nd of the shaft member 60.
