【発明の属する技術分野】
本発明は、中央スイッチの外周に外周スイッチを設置し、これら各スイッチ上に配置した押圧部材を押圧することで各スイッチをオンオフ動作させる構造の多方向押圧型スイッチに関するものである。
【0002】
【従来の技術】
従来、車載用ナビゲーションシステム、コンピュータ、各種携帯機器、各種OA機器、ゲーム機などを操作するデバイスとして、多方向押圧型スイッチがある。そして多方向押圧型スイッチの中には、円盤状(パッド状)の揺動つまみの中央に押釦つまみを設けた構造のものがある。この多方向押圧型スイッチの一使用例としては、揺動つまみで各種機能を選択し、中央の押釦つまみでその機能を確定するなどである。
【0003】
そして部品点数が少なく、その構造・組み立てが簡単で小型化・薄型化が図れる多方向押圧型スイッチとして、図5に示す多方向押圧型スイッチ300がある(特許文献1の図4参照)。この多方向押圧型スイッチ300は、押釦つまみ310と、押釦つまみ310を中央の貫通孔333に挿通した状態で揺動する揺動つまみ330とを可撓性フイルムからなる連結部材350上に取り付け、連結部材350によって一体化された押釦つまみ310と揺動つまみ330とを取付板370上に固定したスイッチ基板390の上に設置し、そのときスイッチ基板390の中央とその周囲四ヵ所(図では二ヶ所のみ示す)に取り付けた反転板(可動接点板)391の上に前記押釦つまみ310の押圧部311と前記揺動つまみ330の四ヶ所の押圧部331(図では二ヶ所のみ示す)とを当接し、さらに前記連結部材350を揺動つまみ330の周囲を覆うケース410の図示しない所定部分に固定して構成されていた。
【0004】
この多方向押圧型スイッチ300によれば、可撓性フイルムからなる薄い連結部材350上に押釦つまみ310と揺動つまみ330とを取り付けるので、その小型・薄型化が図れる。
【0005】
そしてさらなる多方向押圧型スイッチ300の外形の小型化が要求された場合は、揺動つまみ330の外形を小型化すると同時に、その下に配置する各反転板391を中央に集約して設置する必要がある。しかしながら、各反転板391は重ねることができないので、中央の反転板391の外周に周囲の反転板391の外周がほぼ接する位置以上には反転板391を集約して設置することができず、このことがさらなる多方向押圧型スイッチ300の外形の小型化を阻害していた。なお反転板391自体の外径の小型化は、その反転作用を確実に行なわせるために限界がある。

【発明が解決しようとする課題】
本発明は上述の点に鑑みてなされたものでありその目的は、外形の小型化が図れる多方向押圧型スイッチを提供することにある。
【0008】
【課題を解決するための手段】
上記問題点を解決するため本発明にかかる多方向押圧型スイッチは、中央スイッチ反転板を取り付けた中央スイッチを設けた中央スイッチ基板と、中央スイッチの外周に位置する外周スイッチ反転板を取り付けた外周スイッチを設けた外周スイッチ基板とを具備し、前記中央スイッチ反転板と外周スイッチ反転板とが互いに向き合う方向に前記両スイッチ基板を上下に積層させ、その際前記中央スイッチ反転板と外周スイッチ反転板とを上下方向にて重なり合わせて配置してなる多方向押圧型スイッチ基板を具備し、さらに前記中央スイッチ基板上に、中央スイッチの上部に位置する押釦つまみと、外周スイッチの上部に位置して揺動する揺動つまみとを設置してなることを特徴とする。
【0011】
また本発明は、前記揺動つまみの下面には前記外周スイッチ反転板を押圧する押圧部を設け、一方前記外周スイッチ基板又は外周スイッチ基板側の部材には前記中央スイッチ反転板を押圧する押圧部を設けたことを特徴とする。
【0012】
また本発明は、前記押釦つまみと揺動つまみは、何れも前記中央スイッチ基板に取り付けられていることを特徴とする。
【0013】
【発明の実施の形態】
以下、本発明の実施の形態を図面を参照して詳細に説明する。
図1は本発明の一実施の形態にかかる多方向押圧型スイッチ1の分解斜視図である。同図に示すようにこの多方向押圧型スイッチ1は、ケース10と、押圧部材(以下この実施の形態では「揺動つまみ」という)30と、押圧部材(以下この実施の形態では「押釦つまみ」という)50と、外周スイッチ基板90と中央スイッチ基板100とを一体に設けた多方向押圧型スイッチ基板80と、基台120とを具備して構成されている。以下各構成部品について説明する。
【0014】
ケース10は合成樹脂をリング状に成形し、中央に開口11を設けて構成されている。ケース10の下面には、等間隔に4つの凹部13が設けられ、各凹部13近傍には下方向に向かって突出する突起状の係止部15が設けられ、また各係止部15の横には下方向に向かって突出する突起状の固定部17が設けられている。
【0015】
図2は揺動つまみ30と押釦つまみ50とを上面側から見た斜視図である。同図及び図1に示すように揺動つまみ30は、合成樹脂を略円盤状に成形して構成されており、その中央には押釦つまみ50を挿入する円形の挿通孔31を設け、またその外周にはつば部32を設け、またその上面の外周近傍には等間隔に四つの矢印形状の押圧方向指示部33を設け、またその下面の前記各押圧方向指示部33に対応する位置には小突起状の押圧部35を設けて構成されている。各押圧部35の両外周側面からは固定部37,37が突出するように設けられている。また揺動つまみ30の下面の挿通孔31の周囲には等間隔に上下方向に延びるガイド溝39が設けられている。
【0016】
次に押釦つまみ50は合成樹脂を略円柱形状に成形して構成されており、押圧部51の下部に押圧部51よりも大径の基板押圧部53を設け、さらにその外周側面からは等間隔に4つのガイド突起55を突出して構成されている。基板押圧部53の下面は平板状であり、下記する中央スイッチ反転板105の外径よりも少し大きく形成されている。
【0017】
多方向押圧型スイッチ基板80は可撓性のある合成樹脂フイルム(例えばポリエチレンテレフタレートフイルム)に、二枚の外周・中央スイッチ基板90,100を設け、これら外周・中央スイッチ基板90,100を連結部110によって一体に連結して構成されている。外周スイッチ基板90は略円形であり、円周状に4つ設けた接点パターンからなる外周スイッチ接点91の上にそれぞれドーム形状の弾性金属板製の外周スイッチ反転板95を設置することでそれぞれ外周スイッチ92を構成し(この外周スイッチ92の場合、外周スイッチ反転板95が可動接点板となっている)、さらに外周スイッチ基板90の上面中央に押圧部挿入用開口97を設けている。また外周スイッチ基板90の周囲には前記ケース10の固定部17を挿入する4つの固定用孔98が設けられ、またその外周からは回路引出部99が突出して設けられている。なお外周スイッチ92はこの構造のものに限定されるものではなく種々の変形が可能であり、例えば二枚の合成樹脂フイルムに設けたスイッチ接点を間隙を持って対向することで形成されるスイッチの上にクリック用の反転板を設置して構成しても良い。
【0018】
一方中央スイッチ基板100は略四角形状であり、中央に設けた1つの中央スイッチ接点101の上に中央スイッチ反転板105を設置することで中央スイッチ102を構成し(この中央スイッチ102の場合も中央スイッチ反転板105が可動接点板となっている)、さらに中央スイッチ反転板105の周囲四ヶ所に前記揺動つまみ30の押圧部35及び固定部37,37を挿通する形状の固定孔103を設け、さらにその外周から三本の引出部107を突出してそれらの先端近傍と前記連結部110とにそれぞれ前記ケース10の係止部15に挿入される係止孔109を設けている。なおこの中央スイッチ102の構造も上記構造に限定されず、例えば二枚の合成樹脂フイルムに設けたスイッチ接点を間隙を持って対向することで形成されるスイッチの上にクリック用の反転板を設置して構成しても良い。
【0019】
基台120は、硬質の例えば金属板によって構成され、前記外周スイッチ基板90の押圧部挿入用開口97に対向する位置には外周スイッチ基板90側の部材である基台120を板金加工によって上方向に凸となるように成形してなる押圧部123を設け、また前記スイッチ基板90の各固定用孔98に対向する位置には貫通部121を設けている。
【0020】
そしてこの多方向押圧型スイッチ1を組み立てるには、まず図1において、揺動つまみ30の挿通孔31にその下面側から押釦つまみ50の押圧部51を挿入した上で、この揺動つまみ30の下面を、中央スイッチ基板100の下面(以下の折り返し工程によって上面となる)に当接する。その際揺動つまみ30の各押圧部35及び固定部37,37は中央スイッチ基板100の固定孔103に挿入される。そして両固定部37,37を熱カシメして潰すことで揺動つまみ30を中央スイッチ基板100に固定する。なおこのとき押釦つまみ50は、そのガイド突起55が揺動つまみ30のガイド溝39内に上下動自在に挿入されガイドされ、揺動つまみ30と中央スイッチ基板100の間に取り付けられている。
【0021】
次に中央スイッチ基板100を取り付けた揺動つまみ30の上面側を、ケース10の開口11にその下面側から挿入する(図1で言えば中央スイッチ基板100を取り付けた揺動つまみ30を図1の矢印Aで示すように揺動つまみ30の上面が上向きとなるように折り返したものをケース10の開口11にその下面側から挿入する)。そのときケース10の各係止部15を中央スイッチ基板100の各係止孔109に挿入し、各係止部15の先端を熱カシメすることでケース10に中央スイッチ基板100を固定する。このとき揺動つまみ30の上面はケース100の開口11からその上面側に露出し、また押釦つまみ50の押圧部51の上面も揺動つまみ30の挿通孔31から露出している(図3参照)。
【0022】
次に中央スイッチ基板100等を取り付けたケース10を、基台120上に載置した外周スイッチ基板90の上に載置し、その際ケース10に設けた各固定部17を外周スイッチ基板90の各固定用孔98と、基台120に設けた各貫通部121に挿入し、基台120の下面で各固定部17の先端を熱カシメして固定すれば、図3に示すような多方向押圧型スイッチ1が完成する。
【0023】
図4は多方向押圧型スイッチ1の概略側断面図(図3のB−B断面図)である。同図に示すように多方向押圧型スイッチ1は、外周スイッチ基板90と中央スイッチ基板100を、外周スイッチ反転板95と中央スイッチ反転板105とが互いに向き合う方向に上下に積層させて設置することで構成される多方向押圧型スイッチ基板80の上部に、中央スイッチ反転板105(即ち中央スイッチ102)上に位置する押釦つまみ50と、外周スイッチ反転板95(即ち外周スイッチ92)上に位置する揺動つまみ30とを設置して構成されている。そしてこのとき揺動つまみ30の各押圧部35は各外周スイッチ反転板95の上面中央に当接又は接近して配置され、一方外周スイッチ基板90の押圧部挿入用開口97内に挿入された押圧部123は中央スイッチ反転板105の上面中央に当接又は接近して配置され、また中央スイッチ基板100の中央スイッチ反転板105を取り付けた部分の裏面は押釦つまみ50の基板押圧部53によって支持されている。また前述のように押釦つまみ50と揺動つまみ30とは、何れも中央スイッチ基板100の上面に取り付けられ、中央スイッチ基板100はケース10に取り付けられている。
【0024】
以上のように構成された多方向押圧型スイッチ1は、中央スイッチ反転板105を取り付けた中央スイッチ基板100と、外周スイッチ反転板95を取り付けた外周スイッチ基板90とを、外周スイッチ反転板95と中央スイッチ反転板105とが互いに向き合う方向に上下に積層させて設置して多方向押圧型スイッチ基板80を構成したので、中央スイッチ反転板105に対して外周スイッチ反転板95を、両者の外周が所定寸法Dにわたって上下方向に重なるように設置することができ、その分中央スイッチ反転板105に対して外周スイッチ反転板95を集約して設置することができ、多方向押圧型スイッチ基板80及び多方向押圧型スイッチ1の小型化が図れる。なお中央スイッチ反転板105は反転した際に外周スイッチ反転板95に接しない程度に上方に位置している。
【0025】
そして押釦つまみ50を押圧すると基板押圧部53が中央スイッチ基板100の下面を押圧してこれを下降させ、押圧部123によって中央スイッチ反転板105が反転して中央スイッチ102がオンする。押釦つまみ50への押圧を解除すると、中央スイッチ反転板105の弾性復帰力によって押釦つまみ50は元の位置に押し上げられ、中央スイッチ102はオフする。
【0026】
一方揺動つまみ30の何れかの押圧方向指示部33の部分を押圧すれば、押圧した部分が下降し、下降した部分の真下の押圧部35がこれに対向する外周スイッチ反転板95を押圧してこれを反転し、外周スイッチ92がオンする。揺動つまみ30への押圧を解除すると、外周スイッチ反転板95の弾性復帰力によって揺動つまみ30は元の位置に押し上げられ、外周スイッチ92はオフする。
【0027】
ところで揺動つまみ30と押釦つまみ50は、可撓性を有するフイルムからなる中央スイッチ基板100上に取り付けられているので、揺動つまみ30と押釦つまみ50の動作をそれぞれほぼ独立して行わせることができるばかりか、両者の一体化とケース10への固定とが容易になり、また構造の簡素化が図れる。
【0028】
以上本発明の実施の形態を説明したが、本発明は上記実施の形態に限定されるものではなく、特許請求の範囲、及び明細書と図面に記載された技術的思想の範囲内において種々の変形が可能である。なお直接明細書及び図面に記載がない何れの形状や構造や材質であっても、本願発明の作用・効果を奏する以上、本願発明の技術的思想の範囲内である。例えば中央スイッチ反転板105を押圧する押圧部123は必ずしも基台120上に設ける必要はなく、例えば図6に示すように外周スイッチ基板90の上面中央(中央スイッチ反転板105の中央に対向する位置)に成形樹脂製の押圧部96を接着材などによって固定して形成しても良い。要はこの押圧部は外周スイッチ基板又は外周スイッチ基板側の何れかの部材に設ければ良い。
【0029】
また上記実施の形態では押釦つまみと揺動つまみとを別々に設けたが、両者は一体成形品で構成しても良い。要は上下に中央・外周スイッチ基板を積層した多方向押圧型スイッチ基板の上部に設置され、中央・外周反転板の各々を押圧・反転させる形状・構造の一又は二以上の押圧部材であればどのような構造の押圧部材であってもよい。
【0030】
【発明の効果】
以上詳細に説明したように本発明によれば以下のような優れた効果を有する。
(1)中央スイッチ反転板と外周スイッチ反転板とが互いに向き合う方向に中央スイッチ基板と外周スイッチ基板とを上下に積層させ、その際中央スイッチ反転板と外周スイッチ反転板とを上下方向にて重なり合わせたので、多方向押圧型スイッチ基板及びこれを用いた多方向押圧型スイッチの外形の小型化が図れる
【0031】
▲2▼外周スイッチ基板側の部材に中央スイッチ反転板を押圧する押圧部を設けたので、別途この押圧部を設ける部材を用意する必要がなく、部品点数の削減が図れ、また組み立ても容易になる。
【0032】
▲3▼押釦つまみと揺動つまみとを何れも中央スイッチ基板の上面に取り付けたので、中央スイッチ基板が押釦つまみと揺動つまみの連結固定部材を兼用し、部品点数の削減が図れる。

[Prior art]
2. Description of the Related Art Conventionally, as a device for operating an in-vehicle navigation system, a computer, various portable devices, various OA devices, game machines, and the like, there is a multi-directional push switch. Some multi-directional push switches have a structure in which a push button knob is provided at the center of a disk-like (pad-like) swing knob. As one example of use of this multi-directional push type switch, various functions are selected with a swing knob, and the function is determined with a central push button knob.
[0003]
A multidirectional press switch 300 shown in FIG. 5 is available as a multidirectional press switch 300 that has a small number of parts, is simple in structure and assembly, and can be reduced in size and thickness (see FIG. 4 of Patent Document 1). This multi-directional push type switch 300 has a push button knob 310 and a swing knob 330 that swings in a state where the push button knob 310 is inserted through a central through hole 333 mounted on a connecting member 350 made of a flexible film. The push button knob 310 and the swing knob 330 integrated by the connecting member 350 are installed on the switch board 390 fixed on the mounting plate 370. At that time, the center of the switch board 390 and four surrounding areas (two in the figure). The pressing portion 311 of the push button knob 310 and the four pressing portions 331 (only two locations are shown in the figure) of the rocking knob 330 are placed on a reversing plate (movable contact plate) 391 attached to only one location. Further, the connecting member 350 is fixed to a predetermined portion (not shown) of the case 410 that covers the periphery of the swing knob 330.
[0004]
According to the multidirectional pressing switch 300, the push button knob 310 and the swing knob 330 are attached to the thin connecting member 350 made of a flexible film, so that the size and thickness of the switch can be reduced.
[0005]
When further downsizing of the outer shape of the multi-directional push switch 300 is required, it is necessary to reduce the outer shape of the swing knob 330 and simultaneously install the reversing plates 391 disposed below it in the center. There is. However, since each reversing plate 391 cannot be overlapped, the reversing plates 391 cannot be collectively installed beyond the position where the outer periphery of the surrounding reversing plate 391 is substantially in contact with the outer periphery of the central reversing plate 391. This hinders further downsizing of the outer shape of the multidirectional pressing switch 300. Note that the reduction of the outer diameter of the reversing plate 391 itself has a limit in order to ensure the reversing action.

The portion 123 is disposed in contact with or close to the center of the upper surface of the central switch reversing plate 105, and the back surface of the central switch substrate 100 to which the central switch reversing plate 105 is attached is supported by the substrate pressing portion 53 of the push button knob 50. ing. Further, as described above, the push button knob 50 and the swing knob 30 are both attached to the upper surface of the central switch board 100, and the central switch board 100 is attached to the case 10.
[0024]
The multi-directional push switch 1 configured as described above includes a central switch board 100 having a central switch reversing plate 105 attached thereto, and an outer peripheral switch board 90 having a peripheral switch reversing plate 95 attached thereto. Since the multi-directional pressing type switch board 80 is configured by stacking up and down in the direction in which the central switch reversing plate 105 faces each other, the outer peripheral switch reversing plate 95 is disposed on the central switch reversing plate 105, and the outer periphery of both is It can be installed so as to overlap in the vertical direction over the predetermined dimension D, and the outer peripheral switch reversing plate 95 can be collectively installed with respect to the central switch reversing plate 105. The size of the direction pressing switch 1 can be reduced. The central switch reversing plate 105 is positioned so as not to contact the outer peripheral switch reversing plate 95 when reversed.
[0025]
When the push button knob 50 is pressed, the substrate pressing portion 53 presses the lower surface of the central switch substrate 100 and lowers it, and the central switch reversing plate 105 is reversed by the pressing portion 123 and the central switch 102 is turned on. When the push on the push button knob 50 is released, the push button knob 50 is pushed up to the original position by the elastic return force of the center switch reversing plate 105, and the center switch 102 is turned off.
[0026]
On the other hand, if any one of the pressing direction indicating portions 33 of the swing knob 30 is pressed, the pressed portion is lowered, and the pressing portion 35 directly below the lowered portion presses the outer peripheral switch reversing plate 95 opposed thereto. This is reversed and the outer peripheral switch 92 is turned on. When the pressing to the swing knob 30 is released, the swing knob 30 is pushed up to the original position by the elastic return force of the outer peripheral switch reversing plate 95, and the outer peripheral switch 92 is turned off.
