本発明によれば、防水パッキンを設けてもキートップの設計の自由度を向上させる電子機器用プッシュボタンを提供することができる。   ADVANTAGE OF THE INVENTION According to this invention, even if it provides waterproof packing, the push button for electronic devices which improves the freedom degree of design of a keytop can be provided.

以下、図面を参照して本発明の実施形態について詳細に説明する。図１Ａと、図１Ｂと図２を参照して実施形態について説明する。図１Ａは、押し下げられる前の状態における電子機器用プッシュボタンの断面図である。図１Ｂは、押し下げられた後の状態における電子機器用プッシュボタンの断面図である。図２は、電子機器用プッシュボタンの分解斜視図である。   Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The embodiment will be described with reference to FIG. 1A, FIG. 1B, and FIG. FIG. 1A is a cross-sectional view of the electronic device push button in a state before being pushed down. FIG. 1B is a cross-sectional view of the electronic device push button in a state after being pushed down. FIG. 2 is an exploded perspective view of the electronic device push button.

図１Ａに示すように電子機器用プッシュボタン１は、外装ケース１０と、外装ケース１０に収納されるプッシュボタン２０と、外装ケース１０を介してプッシュボタン２０を押圧するキートップ３０と、外装ケース１０とキートップ３０の間に配置されるパッキン４０を有する。   As shown in FIG. 1A, an electronic device push button 1 includes an outer case 10, a push button 20 accommodated in the outer case 10, a key top 30 that presses the push button 20 through the outer case 10, and an outer case. 10 and a packing 40 disposed between the key tops 30.

図１Ａに示すように外装ケース１０には、円筒部であるボス１１が突設されている。ボス１１の中心には、キートップ３０の軸部３２が貫通可能な貫通孔１２が形成されている。またボス１１の周囲には、ボス１１と同心に環状の溝１５が設けられている。この溝１５内には、パッキン４０の下部フランジ４２（詳細については後述する）がボス１１を締め付けるように嵌合配置可能で、さらにボス１１と同心に環状の溝１４が設けられている。溝１４は、下部フランジ４２と略同じ高さを有している。溝１５には、後述するキートップ３０の先端３２ａが貫通孔１２に挿入されると、キートップ３０における外周壁部３３が挿入配置される。また溝１５の周囲には、外周壁部３３が遊嵌可能な側壁１６が設けられている。側壁１６は、外周壁部３３と例えば同形状を有し、外周壁部３３との間には所望する間隔が設けられる。   As shown in FIG. 1A, a boss 11 that is a cylindrical portion protrudes from the outer case 10. A through hole 12 through which the shaft portion 32 of the key top 30 can pass is formed at the center of the boss 11. An annular groove 15 is provided around the boss 11 so as to be concentric with the boss 11. In this groove 15, a lower flange 42 (details will be described later) of the packing 40 can be fitted and arranged to fasten the boss 11, and an annular groove 14 is provided concentrically with the boss 11. The groove 14 has substantially the same height as the lower flange 42. When a tip 32 a of a key top 30 described later is inserted into the through-hole 12 in the groove 15, the outer peripheral wall portion 33 of the key top 30 is inserted and disposed. In addition, a side wall 16 on which the outer peripheral wall 33 can be loosely fitted is provided around the groove 15. The side wall 16 has, for example, the same shape as the outer peripheral wall portion 33, and a desired interval is provided between the side wall 16 and the outer peripheral wall portion 33.

外装ケース１０に収納されるプッシュボタン２０は、貫通孔１２の下方に配置される。   The push button 20 housed in the exterior case 10 is disposed below the through hole 12.

キートップ３０は、外装ケース１０より露出し、操作部でありボス１１の上方に配置される逆椀状の頭部３１と、頭部３１の中央部に配置され、貫通孔１２を貫通し、先端３２ａがプッシュボタン２０を押圧する例えば円柱形状の軸部３２と、を有している。   The key top 30 is exposed from the outer case 10 and is disposed at the center portion of the head 31 that is an operation unit that is disposed above the boss 11 and the center of the head 31, and penetrates the through hole 12. The front end 32 a has, for example, a cylindrical shaft portion 32 that presses the push button 20.

頭部３１は、頭部３１の外周において外装ケース１０に向かって延設され、且つ軸部３２の周囲に配置される外周壁部３３と、軸部３２と外周壁部３３の間に配置され、外装ケース１０に対向する面３５を有している。   The head portion 31 extends toward the exterior case 10 on the outer periphery of the head portion 31 and is disposed between the outer peripheral wall portion 33 disposed around the shaft portion 32 and the shaft portion 32 and the outer peripheral wall portion 33. The surface 35 is opposed to the outer case 10.

キートップ３０は軸部３２の長手軸方向に移動可能であり、これにより先端３２ａがプッシュボタン２０を押圧する。またキートップ３０は、軸部３２の長手軸に対して周方向に回転可能である。このようにキートップ３０は、回転性を有している。   The key top 30 is movable in the longitudinal axis direction of the shaft portion 32, whereby the tip 32 a presses the push button 20. Further, the key top 30 is rotatable in the circumferential direction with respect to the longitudinal axis of the shaft portion 32. As described above, the key top 30 is rotatable.

軸部３２は、キートップ３０が外装ケース１０から抜けることを防止する抜け止めピン３２ｂを有している。抜け止めピン３２ｂは、貫通孔１２の直径よりも長く形成され、外装ケース１０の内面に係止されることによりキートップ３０が外装ケース１０から抜けることを防止する。またキートップ３０がプッシュボタン２０を押圧する方向に移動し、さらに所定の方向に回転すると、抜け止めピン３２ｂは外装ケース１０の内面に設けられた凸部１７に係止される。これによりキートップ３０は、プッシュボタン２０を押圧した状態で保持される。   The shaft portion 32 has a retaining pin 32 b that prevents the key top 30 from being detached from the exterior case 10. The retaining pin 32 b is formed to be longer than the diameter of the through hole 12 and is locked to the inner surface of the exterior case 10 to prevent the key top 30 from being detached from the exterior case 10. When the key top 30 moves in the direction of pressing the push button 20 and further rotates in a predetermined direction, the retaining pin 32b is locked to the convex portion 17 provided on the inner surface of the exterior case 10. Thereby, the key top 30 is held in a state where the push button 20 is pressed.

本発明に係る電子機器用プッシュボタン１が例えば図示しない無線端末に適用され、プッシュボタン２０がＰＴＴ（Ｐｕｓｈ（Ｐｒｅｓｓ） Ｔｏ Ｔａｌｋ）のオン・オフを行うボタンである場合、キートップ３０を図１Ｂに示す位置に保持することにより、操作者は通話を継続することができる。   When the electronic device push button 1 according to the present invention is applied to a wireless terminal (not shown), for example, and the push button 20 is a button for turning on / off the PTT (Push (Press) To Talk), the key top 30 is shown in FIG. By holding the position shown in FIG. 2, the operator can continue the call.

外周壁部３３は、先端３２ａがプッシュボタン２０を押圧する際、溝１５に当接し、後述するパッキン４０の外面４５と側壁１６の間で遊嵌する。そのため外面４５と外周壁部３３の間、及び外周壁部３３と側壁１６の間には、それぞれ所望する間隙が設けられている。   The outer peripheral wall 33 abuts on the groove 15 when the tip 32 a presses the push button 20, and loosely fits between an outer surface 45 of the packing 40 and a side wall 16 described later. Therefore, desired gaps are respectively provided between the outer surface 45 and the outer peripheral wall portion 33 and between the outer peripheral wall portion 33 and the side wall 16.

図１Ａに示すように外装ケース１０とキートップ３０の間には、図２に示すパッキン４０が配置されている。パッキン４０は、弾力性を有し、水分を吸収しない材質、例えばシリコンゴムや軟質合成樹脂等によって形成される。パッキン４０は、図１Ａと図１Ｂに示すようにパッキン４０の軸方向に沿って弾性変形（伸縮）可能である。つまりパッキン４０は、押圧されるキートップ３０の動作に追従して弾性変形する。本実施形態におけるパッキン４０は、半球形状であり、中空部４１を有している。   As shown in FIG. 1A, a packing 40 shown in FIG. 2 is disposed between the outer case 10 and the key top 30. The packing 40 is made of a material that has elasticity and does not absorb moisture, such as silicon rubber or soft synthetic resin. As shown in FIGS. 1A and 1B, the packing 40 can be elastically deformed (stretched) along the axial direction of the packing 40. That is, the packing 40 is elastically deformed following the operation of the pressed key top 30. The packing 40 in this embodiment is hemispherical and has a hollow portion 41.

図１Ａと図２に示すようにパッキン４０の底面部には、パッキン４０の軸に対して外向きと内向きに張り出される環状の下部フランジ４２が設けられている。下部フランジ４２の中央部には、ボス１１と同形状を有し、中空部４１と連通し、ボス１１が貫通可能な貫通孔４２ａが設けられている。この下部フランジ４２は、上述したように溝１４に嵌合配置され、貫通孔４２ａに差し込まれたボス１１の外周に密着し、ボス１１の外周を締め付ける。このように下部フランジ４２は、ボス１１の外周を締め付ける第１の締付部である。なおボス１１は、貫通孔４２ａを貫通し、中空部４１に配置され、パッキン４０の内周面４６に当接しない。また下部フランジ４２には、外周壁部３３が溝１５に当接した際、図１Ｂに示すように外周壁部３３が当接する。   As shown in FIGS. 1A and 2, an annular lower flange 42 is provided on the bottom surface of the packing 40 so as to project outward and inward with respect to the shaft of the packing 40. A central portion of the lower flange 42 is provided with a through hole 42a that has the same shape as the boss 11, communicates with the hollow portion 41, and allows the boss 11 to pass therethrough. As described above, the lower flange 42 is fitted and disposed in the groove 14, closely contacts the outer periphery of the boss 11 inserted into the through hole 42 a, and tightens the outer periphery of the boss 11. Thus, the lower flange 42 is a first tightening portion that tightens the outer periphery of the boss 11. The boss 11 passes through the through hole 42 a, is disposed in the hollow portion 41, and does not contact the inner peripheral surface 46 of the packing 40. Further, when the outer peripheral wall portion 33 contacts the groove 15, the outer peripheral wall portion 33 contacts the lower flange 42 as shown in FIG. 1B.

また図２に示すようにパッキン４０の頂部には、パッキン４０の軸に向かって内向きに張り出される上部フランジ４３を有している。上部フランジ４３の中央部には、軸部３２と同形状を有し、中空部４１と連通し、軸部３２が貫通可能な貫通孔４３ａが設けられている。環状の上部フランジ４３は、内向きに張り出されるため、図１Ａに示すように貫通孔４３ａに差し込まれた軸部３２に密着し、軸部３２の外周を締め付け、また面３５に当接する。このように上部フランジ４３は、軸部３２を締め付ける第２の締付部である。なお軸部３２が締め付けられた状態においても、キートップ３０は上述したように軸部３２の長手軸に対して周方向に回転可能である。
貫通孔４３ａは、貫通孔４２ａよりも小さく、貫通孔１２の上方に配置される。 As shown in FIG. 2, the top of the packing 40 has an upper flange 43 that protrudes inward toward the axis of the packing 40. A central portion of the upper flange 43 is provided with a through hole 43 a that has the same shape as the shaft portion 32, communicates with the hollow portion 41, and allows the shaft portion 32 to pass therethrough. Since the annular upper flange 43 protrudes inward, as shown in FIG. 1A, the annular upper flange 43 comes into close contact with the shaft portion 32 inserted into the through hole 43 a, tightens the outer periphery of the shaft portion 32, and contacts the surface 35. Thus, the upper flange 43 is a second tightening portion that tightens the shaft portion 32. Even in a state where the shaft portion 32 is tightened, the key top 30 can rotate in the circumferential direction with respect to the longitudinal axis of the shaft portion 32 as described above.
The through hole 43 a is smaller than the through hole 42 a and is disposed above the through hole 12.

このようにパッキン４０は、下部フランジ４２によってボス１１の外周を締め付けさせ、上部フランジ４３によって軸部３２を締め付けさせることで中空部４１を気密封止する。これによりパッキン４０は、外部から中空部４１を防水し、軸部３２と外装ケース１０を介してプッシュボタン２０を防水する。なお本実施形態のパッキン４０の防止機能は、キートップ３０がいかなる操作状態にあってもＩＰＸ５の保護等級を維持することが可能である。   In this way, the packing 40 tightly seals the hollow portion 41 by tightening the outer periphery of the boss 11 with the lower flange 42 and tightening the shaft portion 32 with the upper flange 43. Accordingly, the packing 40 waterproofs the hollow portion 41 from the outside, and waterproofs the push button 20 via the shaft portion 32 and the exterior case 10. In addition, the prevention function of the packing 40 of this embodiment can maintain the IPX5 protection class regardless of the operation state of the key top 30.

次に本実施形態のキートップの押圧の動作方法について図１Ａと図１Ｂを参照して説明する。
図１Ｂに示すように頭部３１が電子機器用プッシュボタン１の操作者によって押圧されると、パッキン４０はパッキン４０の軸方向に沿って圧縮されて弾性変形する。このとき、パッキン４０の上部フランジ４３は、軸部３２を締め付けた状態を保持し、防水性を維持する。なおキートップ３０は、外周壁部３３の底面が溝１５に当接するまで押圧可能である。 Next, the key top pressing operation method of this embodiment will be described with reference to FIGS. 1A and 1B.
When the head 31 is pressed by the operator of the electronic device push button 1 as shown in FIG. 1B, the packing 40 is compressed along the axial direction of the packing 40 and elastically deformed. At this time, the upper flange 43 of the packing 40 maintains a state in which the shaft portion 32 is tightened, and maintains waterproofness. The key top 30 can be pressed until the bottom surface of the outer peripheral wall portion 33 abuts the groove 15.

キートップ３０が押圧された状態から解放されると、パッキン４０は圧縮される元の形状に戻る。その際、キートップ３０は、パッキン４０の弾性力により、押し上げられ、キートップ３０とパッキン４０とプッシュボタン２０は、図１Ａに示す状態に戻る。   When the key top 30 is released from the pressed state, the packing 40 returns to the original shape to be compressed. At that time, the key top 30 is pushed up by the elastic force of the packing 40, and the key top 30, the packing 40, and the push button 20 return to the state shown in FIG. 1A.

なおパッキン４０が弾性変形し、上部フランジ４３の位置が変化しても、上部フランジ４３は断面視円形を呈するため、軸部３２との接触が確保される。またパッキン４０は半球形状を有しているため、図１Ｂに示すようにパッキン４０が弾性変形（圧縮）しても、上部フランジ４３は、外側に膨らむことを抑制され、軸部３２を確実に締め付ける。   Even when the packing 40 is elastically deformed and the position of the upper flange 43 is changed, the upper flange 43 has a circular shape in cross section, so that contact with the shaft portion 32 is ensured. Further, since the packing 40 has a hemispherical shape, even when the packing 40 is elastically deformed (compressed) as shown in FIG. 1B, the upper flange 43 is restrained from expanding outward, and the shaft portion 32 is reliably secured. tighten.

このように本実施形態は、パッキン４０にて防水するために、弾力性を有する上部フランジ４３に軸部３２を締め付けさせ、上部フランジ４３を軸部３２と面３５に当接させている。よって外周壁部３３には、上部フランジ４３が当接しないため、外周壁部３３の設計上の制約は生じない。また、外周壁部３３の形状を簡素化できるため、コスト的にも有利である。またパッキン４０の上部フランジ４３を内向きに張り出させ、軸部３２を締め付けるようにしているため、上部フランジ４３を嵌合させる嵌合部材を軸部３２に設ける必要がない。   Thus, in this embodiment, in order to waterproof the packing 40, the shaft portion 32 is fastened to the elastic upper flange 43, and the upper flange 43 is brought into contact with the shaft portion 32 and the surface 35. Therefore, the upper flange 43 does not come into contact with the outer peripheral wall portion 33, so that the design of the outer peripheral wall portion 33 is not restricted. Moreover, since the shape of the outer peripheral wall part 33 can be simplified, it is advantageous also in cost. In addition, since the upper flange 43 of the packing 40 protrudes inward and the shaft portion 32 is tightened, it is not necessary to provide a fitting member for fitting the upper flange 43 in the shaft portion 32.

このように本実施形態は、防水のためにパッキン４０を設けてもキートップ３０の形状を簡素にでき、キートップ３０の設計の自由度を向上させることができ、安価にすることができる。   As described above, in the present embodiment, even if the packing 40 is provided for waterproofing, the shape of the key top 30 can be simplified, the degree of freedom in designing the key top 30 can be improved, and the cost can be reduced.

また本実施形態は、キートップ３０を押し上げ、押し下げ、回転させても、上部フランジ４３における軸部３２との接触面積は、変化していない。これにより本実施形態は、キートップ３０を押し上げ、押し下げ、回転させる際、パッキン４０がどのように変形しても上部フランジ４３に対する軸部３２における抵抗の変化が生じないために、操作者に均一な操作感覚を得させることができる。   In this embodiment, even if the key top 30 is pushed up, pushed down, and rotated, the contact area with the shaft portion 32 in the upper flange 43 does not change. Accordingly, in the present embodiment, when the key top 30 is pushed up, pushed down, and rotated, no change occurs in the resistance of the shaft portion 32 with respect to the upper flange 43 no matter how the packing 40 is deformed. You can get a sense of operation.

また本実施形態は、パッキン４０を半球形状とし、上部フランジ４３を内向きに張り出させているために、パッキン４０が縮んだ際、パッキン４０がキートップ３０に当接することを抑制できるため、スムーズに操作させることができる。   Further, in the present embodiment, since the packing 40 has a hemispherical shape and the upper flange 43 protrudes inward, the packing 40 can be prevented from coming into contact with the key top 30 when the packing 40 is contracted. It can be operated smoothly.

また本実施形態は、上部フランジ４３に例えば潤滑剤を塗布してもよい。これにより本実施形態は、キートップ３０の操作性を向上させることができる。   In the present embodiment, for example, a lubricant may be applied to the upper flange 43. Thereby, this embodiment can improve the operativity of the keytop 30. FIG.

また本実施形態は、パッキン４０の弾性力により、キートップ３０を押し上げることができるため、バネなどの他の部材を用いることなくキートップ３０を図１Ａに示す状態に戻すことができる。   Further, in the present embodiment, the key top 30 can be pushed up by the elastic force of the packing 40, so that the key top 30 can be returned to the state shown in FIG. 1A without using other members such as a spring.

また本実施形態は、図１Ｂに示すように先端３２ａがプッシュボタン２０を押圧する際、キートップ３０の外周壁部３３の底面を溝１５（外装ケース１０）に当接させることで、操作者に先端３２ａによるプッシュボタン２０の押圧動作が完了したことを判別させることができる。   Further, in the present embodiment, as shown in FIG. 1B, when the tip 32a presses the push button 20, the bottom surface of the outer peripheral wall portion 33 of the key top 30 is brought into contact with the groove 15 (exterior case 10). It is possible to determine that the pressing operation of the push button 20 by the tip 32a has been completed.

なお本実施形態において、パッキン４０は、半球形状を有しているが、プッシュボタン２０を防水することができれば、例えば円筒形状やコの字形状でも良く、その形状は限定されない。   In the present embodiment, the packing 40 has a hemispherical shape. However, as long as the push button 20 can be waterproofed, for example, a cylindrical shape or a U-shape may be used, and the shape is not limited.

このように本発明は、上記実施形態そのままに限定されるものではなく、実施段階ではその要旨を逸脱しない範囲で構成要素を変形して具体化できる。また、上記実施形態に開示されている複数の構成要素の適宜な組み合せにより種々の発明を形成できる。   As described above, the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. Further, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the embodiment.
