Description

【０００１】
【発明の属する技術分野】
本発明は、自動車や各種電子機器の操作に用いられる多連プッシュスイッチに関するものである。
【０００２】
【従来の技術】
近年、自動車や各種電子機器の高機能化・多様化が進むに伴い、これらの複数の操作部が集中して配置されると共に、周囲が暗い場合でも相違のし易い照光機能を備えた多連プッシュスイッチが多く用いられている。
【０００３】
このような従来の多連プッシュスイッチについて図５〜図７を用いて説明する。
【０００４】
図５は従来の多連プッシュスイッチの断面図、図６は同分解斜視図であり、同図において、１は乳白色で絶縁樹脂製の操作体で、下面に中空部を設けた複数の箱状の押釦１Ａが、側面のヒンジ１Ｂによって板状の連結部１Ｃに一列に連結されると共に、押釦１Ａの上面には文字や記号、絵柄等（図示せず）が表示されている。
【０００５】
そして、２は操作体１の下方に配置された配線基板で、この配線基板２の上下面には複数の配線パターン（図示せず）が形成されると共に、上面には押釦１の下面に突出した押圧部１Ｄによって押圧操作され、電気的接離を行う複数のプッシュスイッチ３が実装されてスイッチ接点が形成されている。
【０００６】
また、４は上面発光の発光ダイオード等の発光素子で、押釦１Ａ下方の配線基板２上面に実装され、プッシュスイッチ３と同様に配線パターンに接続されている。
【０００７】
さらに、５は操作体１や配線基板２を覆う遮光性で絶縁樹脂製のカバーで、このカバー５上面の開口部５Ａには、側面が隣接して上方に突出した一対の操作体１が配置されると共に、この操作体１は押釦１Ａが上下動可能なように、連結部１Ｃがカバー５裏面に保持されて多連プッシュスイッチが構成されている。
【０００８】
以上の構成において、所定の押釦１Ａを下方へ押圧操作すると、ヒンジ１Ｂが弾性変形し、これを支点として押釦１Ａが下方へ傾き、下面の押圧部１Ｄに押圧されたプッシュスイッチ３が電気的接離を行って、この信号が複数の配線基板２の配線パターンから機器の電子回路（図示せず）へ出力される。
【０００９】
また、機器の電子回路から発光素子４に電圧が印加されると、発光素子４上面が発光し、この光が押釦１Ａを後方から照光するため、周囲が暗い場合でも、押釦１の位置確認や文字等の視認が容易に行えるように構成されているものであった。
【００１０】
なお、この出願の発明に関連する先行技術文献情報としては、例えば、特許文献１が知られている。

【００１２】
【発明が解決しようとする課題】
しかしながら上記従来の多連プッシュスイッチにおいては、複数の押釦１Ａが側面のヒンジ１Ｂで連結部１Ｃに一列に連結された操作体１を用い、押釦１Ａを傾けて上下動させているため、図７の平面図に示すように、複数の押釦１Ａの側面が対向する箇所には所定の隙間Ｌが必要となり、この隙間Ｌからスイッチの内部が見えたり、発光素子４の光が漏れ易いという課題があった。
【００１３】
また、複数の押釦１Ａがヒンジ１Ｂで連結された操作体１を用いているため、例えば、これを二列より多くの列に並べて配置したり、一つの押釦を中心に、その外周に複数の押釦を配置したりする場合、構成が複雑となり、そのレイアウトにも制限のあるものであった。
【００１４】
本発明は、このような従来の課題を解決するものであり、押釦間からスイッチ内部が見え難く外部への光漏れも少ないと共に、多様な多連構成も可能な多連プッシュスイッチを提供することを目的とする。
【００１５】
【課題を解決するための手段】
上記課題を解決するために本発明は、以下の構成を有するものである。
【００１６】
本発明の請求項１に記載の発明は、隣接する複数の押釦をカバーの保持部で上下動可能に保持すると共に、複数の押釦の隣接する外周側面に、互いに突出し重なり合う凸部を設けて多連プッシュスイッチを構成したものであり、互いに重なり合う凸部によって、隣接する押釦の外周側面の隙間が見えなくなるため、押釦間からスイッチ内部が見え難く外部への光漏れも少ないと共に、複数の押釦がヒンジ等で連結されていないため、多様な多連構成も可能な多連プッシュスイッチを得ることができるという作用を有する。
【００１７】
請求項２に記載の発明は、請求項１記載の発明において、カバーの保持部を筒状に形成し、この外周に凸状または凹状の案内部を設けると共に、押釦内周に前記案内部に対応する凹状または凸状の係合部を設けたものであり、カバーの案内部によって押釦の係合部をガイドできるため、押釦とカバーとのがたつきが小さくなり、押釦の上下動操作時にがたつきが少なく操作感触の良好なものを得ることができるという作用を有する。
【００１８】
【発明の実施の形態】
以下、本発明の実施の形態について、図１〜図４を用いて説明する。
【００１９】
（実施の形態）
図１は本発明の一実施の形態による多連プッシュスイッチの断面図、図２は同分解斜視図、図３は同平面図であり、同図において、１１はＡＢＳやポリカーボネイト、アクリル等の絶縁樹脂製の半透明或いは乳白色等の光透過性の複数の押釦で、この下面に中空部１１Ａを設けた箱状の押釦１１の上面には、印刷等によって文字や記号、絵柄等（図示せず）が表示されると共に、下面には下方に突出した押圧部１１Ｂが形成されている。
【００２０】
また、これら複数の押釦１１は各々の外周側面を隣接させて縦横に列状に配置されると共に、例えば、三列に配置された押釦１１Ｃと１１Ｄ及び１１Ｅの隣接する外周側面には、互いに突出し重なり合う凸部が設けられている。
【００２１】
つまり、押釦１１Ｃの右側面下方には凸部１１Ｆが、これと隣接する押釦１１Ｄの左側面上方には凸部１１Ｇが突出して設けられ、押釦１１Ｃの右側面上方と押釦１１Ｄの左側面下方は各々窪んで、凸部１１Ｆと凸部１１Ｇが上下方向へ互いに重なり合うようにして形成されている。
【００２２】
なお、押圧操作時に上下動可能なように、凸部１１Ｆの下方、及び凸部１１Ｆと凸部１１Ｇの間には、所定の間隙が形成されている。
【００２３】
同様に、押釦１１Ｄの右側面下方には凸部１１Ｈ、これと隣接する押釦１１Ｅの左側面上方には凸部１１Ｊが、各々上下方向へ互いに重なり合うようにして形成されている。
【００２４】
そして、１２は押釦１１の下方に配置された配線基板で、この配線基板１２の上下面には複数の配線パターン（図示せず）が形成されると共に、配線基板１２上面には、上方に付勢された操作部が押釦１１の押圧部１１Ｂによって押圧操作されて電気的接離を行う、複数のプッシュスイッチ１３が実装されてスイッチ接点が形成されている。
【００２５】
また、１４は上面発光の発光ダイオード等の発光素子で、押釦１１の中空部１１Ａ下方の配線基板１２上面に実装され、プッシュスイッチ１３と同様に配線パターンに接続されている。
【００２６】
さらに、１５は配線基板１２を覆うＡＢＳやポリカーボネイト等の絶縁樹脂製で遮光性のカバーで、額縁状の枠部１５Ａの内側には、中空筒状の複数の保持部１５Ｂが縦横に列状に設けられ、この保持部１５Ｂによって、カバー１５上面から縦横に列状に突出した押釦１１Ｃや１１Ｄ，１１Ｅ等の複数の押釦１１が、上下動可能に保持されている。
【００２７】
また、この保持部１５Ｂの外周四側面には、各々上下方向に凹状の案内部１５Ｃが設けられ、この案内部１５Ｃには、押釦１１内周に設けられた凸状で、案内部１５Ｃよりもやや小さな幅の係合部１１Ｋが各々挿入されている。
【００２８】
そして、各押釦１１下面から突出した押圧部１１Ｂは、カバー１５の保持部１５Ｂ間または保持部１５Ｂと枠部１５Ａの間の、溝部１５Ｄの底面に形成した孔１５Ｅを挿通し、下端がプッシュスイッチ１３の上面に当接して多連プッシュスイッチが構成されている。
【００２９】
以上の構成において、所定の押釦１１を下方へ押圧操作すると、押釦１１が下方へ移動し、この下面の押圧部１１Ｂに上面の操作部を押圧されたプッシュスイッチ１３が電気的接離を行って、この信号が複数の配線基板１２の配線パターンから機器の電子回路（図示せず）へ出力される。
【００３０】
なお、この時、押釦１１は内周の係合部１１Ｋが、カバー１５の保持部１５Ｂ外周の案内部１５Ｃに四方向をガイドされて下方へ移動するため、押釦１１とカバー１５とのがたつきが小さく、良好な感触で押圧操作が行われる。
【００３１】
そして、機器の電子回路から発光素子１４に電圧が印加されると、発光素子１４上面が発光し、この光が保持部１５Ｂ内を通って、押釦１１を後方から照光するため、周囲が暗い場合でも、押釦１１の位置確認や文字等の視認が容易に行えるように構成されている。
【００３２】
また、この時、発光素子１４の光がカバー１５の孔１５Ｅの隙間から溝部１５Ｄ底面に漏れるが、前述したように、この各押釦１１の隣接する溝部１５Ｄでは、各押釦１１に互いに突出し重なり合う凸部が上下方向に設けられ、隣接する押釦１１の外周側面の隙間が覆われて、押釦１１上面へは光が漏れ難くなっているため、押釦１１は中空部１１Ａ上面の表示面のみが明るく照光される。
【００３３】
このように本実施の形態によれば、隣接する複数の押釦１１をカバー１５の保持部１５Ｂで上下動可能に保持すると共に、複数の押釦１１の隣接する外周側面に、互いに突出し重なり合う凸部１１Ｆ〜１１Ｊを設けることによって、隣接する押釦１１の外周側面の隙間が見えなくなるため、押釦間からスイッチ内部が見え難く、外部への光漏れも少ない多連プッシュスイッチを得ることができるものである。
【００３４】
また、複数の押釦１１がカバー１５の保持部１５Ｂで各々上下動可能に保持されているため、押釦１１を前述したように三列、またはそれ以上の列数で配置したり、或いは、図４の平面図に示すように、一つの押釦１１Ｌを中心に、その外周に複数の押釦１１Ｍを放射状に配置する等、多様なレイアウトを行うことも可能となる。
【００３５】
さらに、カバー１５の筒状の保持部１５Ｂ外周に、凹状の案内部１５Ｃを設けると共に、押釦１１内周にこれに対応する凸状の係合部１１Ｋを設けることによって、案内部１５Ｃで係合部１１Ｋをガイドできるため、押釦１１とカバー１５とのがたつきが小さくなり、押釦の上下動操作時にがたつきが少なく良好な操作を行うことができる。
【００３６】
なお、これとは逆に、押釦１１の係合部を凹状に形成し、対応するカバー１５の案内部を凸状に形成しても、本発明の実施は可能である。
【００３７】
また、以上の説明では、押釦１１を半透明或いは乳白色等の光透過性で、上面に文字や記号、絵柄等を表示した構成のものとして説明したが、押釦全体は暗色とし、この上面に半透明或いは乳白色の光透過性で文字や記号、絵柄等の形状の照光部を、二色成形等によって露出させたものとしてもよい。
【００３８】
【発明の効果】
以上のように本発明によれば、押釦間からスイッチ内部が見え難く外部への光漏れも少ないと共に、多様な多連構成も可能な多連プッシュスイッチを得ることができるという有利な効果が得られる。

For example, the push buttons 11C and 11D and 11E arranged in three rows protrude from each other on adjacent outer peripheral sides. Overlapping projections are provided.
[0021]
That is, a convex portion 11F is provided below the right side of the push button 11C, and a convex portion 11G is provided so as to protrude above the left side of the push button 11D adjacent thereto, and the upper right side of the push button 11C and the lower left side of the push button 11D are provided. The projections 11F and 11G are formed so as to be depressed, respectively, and overlap each other in the vertical direction.
[0022]
A predetermined gap is formed below the convex portion 11F and between the convex portion 11F and the convex portion 11G so as to be able to move up and down during the pressing operation.
[0023]
Similarly, a convex portion 11H is formed below the right side surface of the push button 11D, and a convex portion 11J is formed above the left side surface of the adjacent push button 11E so as to overlap each other in the vertical direction.
[0024]
Reference numeral 12 denotes a wiring board disposed below the push button 11. A plurality of wiring patterns (not shown) are formed on the upper and lower surfaces of the wiring board 12, and an upper surface is provided on the upper surface of the wiring board 12. A plurality of push switches 13 are mounted, and a switch contact is formed, in which the energized operation unit is pressed and operated by the pressing unit 11B of the push button 11 to electrically connect and disconnect.
[0025]
Reference numeral 14 denotes a light-emitting element such as a top-emitting light-emitting diode, which is mounted on the upper surface of the wiring board 12 below the hollow portion 11A of the push button 11 and connected to a wiring pattern in the same manner as the push switch 13.
[0026]
Further, reference numeral 15 denotes a light-shielding cover made of an insulating resin such as ABS or polycarbonate which covers the wiring board 12, and a plurality of hollow cylindrical holding parts 15B are arranged in rows and columns inside the frame 15A. A plurality of pushbuttons 11 such as pushbuttons 11C, 11D, and 11E protruding vertically and horizontally from the upper surface of the cover 15 are held by the holding portion 15B so as to be vertically movable.

As described above, according to the present embodiment, the plurality of adjacent push buttons 11 are held by the holding portion 15B of the cover 15 so as to be able to move up and down, and the protruding portions 11F that protrude and overlap with the outer peripheral side surfaces adjacent to the plurality of push buttons 11 are provided. By providing ~ 11J, the gap on the outer peripheral side surface of the adjacent push button 11 becomes invisible, so that it is difficult to see the inside of the switch from between the push buttons, and it is possible to obtain a multiple push switch with little light leakage to the outside.
[0034]
In addition, since the plurality of push buttons 11 are each held up and down by the holding portion 15B of the cover 15, the push buttons 11 are arranged in three rows or more rows as described above, or FIG. As shown in the plan view, various layouts can be performed, for example, with one push button 11L at the center and a plurality of push buttons 11M arranged radially on the outer periphery.
[0035]
Further, a concave guide portion 15C is provided on the outer periphery of the cylindrical holding portion 15B of the cover 15, and a corresponding convex engagement portion 11K is provided on the inner periphery of the push button 11, whereby the engagement with the guide portion 15C is achieved. Since the portion 11K can be guided, rattling between the push button 11 and the cover 15 is reduced, and a favorable operation can be performed with less rattling during the vertical movement operation of the push button.
[0036]
Conversely, the present invention can be implemented even if the engaging portion of the push button 11 is formed in a concave shape and the corresponding guide portion of the cover 15 is formed in a convex shape.
[0037]
Further, in the above description, the push button 11 is described as having a translucent or milky white light transmissive structure in which characters, symbols, patterns, etc. are displayed on the upper surface. The transparent or milky white light-transmitting illuminating portion having a shape such as a character, a symbol, or a picture may be exposed by two-color molding or the like.
