特開２００１−２１６８６０号公報 The following Patent Document 1 is known as a technical configuration related to the present invention.
JP 2001-216860 A

上記したスイッチ装置１の場合、部品点数が多く、組み付け工数が多くなり、また、製造コストが高くなるという不具合があった。
このような不具合を解消するスイッチ装置として、本発明は、図５及び図６に示すような構成のスイッチ装置１２を開発した。このスイッチ装置１２は、２個のスライドピン７、８の代わりに１個のシーソ部材１３を用いるように構成したものである。このシーソ部材１３は、シーソノブ６とプッシュスイッチ３、４との間に配置されていると共に、基板２上に設けられた支持部材１４により回動可能に指示されている。この場合、シーソ部材１３の回動支点は、シーソノブ６の回動支点５よりも下方になっている。 In the case of the switch device 1 described above, there are problems that the number of parts is large, the number of assembling steps is large, and the manufacturing cost is high.
As a switch device for solving such a problem, the present invention has developed a switch device 12 having a structure as shown in FIGS. The switch device 12 is configured to use one seesaw member 13 instead of the two slide pins 7 and 8. The seesaw member 13 is disposed between the seesaw knob 6 and the push switches 3 and 4 and is instructed to be rotatable by a support member 14 provided on the substrate 2. In this case, the rotation fulcrum of the seesaw member 13 is below the rotation fulcrum 5 of the seesaw knob 6.

そして、上記スイッチ装置１２の場合、シーソノブ６の右端部を手指で下方へ押すと、図６に示すように、シーソノブ６の押圧凸部６ａがシーソ部材１３を押し、このシーソ部材１３がプッシュスイッチ３を押圧操作するように構成されている。この場合、シーソ部材１３は、シーソノブ６の操作力をプッシュスイッチ３に伝達する。更に、シーソノブ６の右端部から手指を離すと、プッシュスイッチ３の復元力により、シーソ部材１３及びシーソノブ６は元の位置（図５参照）へ戻る。   In the case of the switch device 12, when the right end of the seesaw knob 6 is pushed downward with a finger, as shown in FIG. 6, the pressing projection 6a of the seesaw knob 6 pushes the seesaw member 13, and the seesaw member 13 is a push switch. 3 is pressed. In this case, the seesaw member 13 transmits the operating force of the seesaw knob 6 to the push switch 3. Further, when the finger is released from the right end portion of the seesaw knob 6, the seesaw member 13 and the seesaw knob 6 are returned to their original positions (see FIG. 5) by the restoring force of the push switch 3.

このとき、異音が発生する。というのは、シーソノブ６の右端部を手指で下方へ押したときに、図６に示すように、シーソ部材１３の左端部の上面部とシーソノブ６の押圧凸部６ｂとの間に隙間があるためである。
本発明の目的は、部品点数をできるだけ少なくしながら、異音が発生することを防止できるスイッチ装置を提供するにある。 At this time, abnormal noise is generated. This is because when the right end of the seesaw knob 6 is pushed downward with fingers, there is a gap between the upper surface of the left end of the seesaw member 13 and the pressing projection 6b of the seesaw knob 6 as shown in FIG. Because.
An object of the present invention is to provide a switch device that can prevent the generation of abnormal noise while minimizing the number of parts.

本発明のスイッチ装置は、中間部分に回動支点が設けられた回動可能なシーソノブを備え、このシーソノブの両端部の下方に設けられシーソノブにより押圧操作される２個のプッシュスイッチを備え、前記シーソノブと前記２個のプッシュスイッチとの間に配置されると共に前記シーソノブの回動支点よりも下方の回動支点の周りに回動可能に設けられ前記シーソノブの操作力を前記プッシュスイッチに伝達するシーソ部材を備え、そして、前記シーソ部材の両端部の上面部に、前記シーソノブの下面部に常時当接するばね手段を設けるように構成したものである。   The switch device of the present invention includes a rotatable seesaw knob provided with a rotation fulcrum at an intermediate portion, and includes two push switches provided below both ends of the seesaw knob and pressed by the seesaw knob. It is disposed between a seesaw knob and the two push switches, and is provided so as to be rotatable around a turning fulcrum below the turning fulcrum of the seesaw knob, and transmits the operating force of the seesaw knob to the push switch. A seesaw member is provided, and spring means that always contacts the lower surface of the seesaw knob is provided on the upper surface of both ends of the seesaw member.

このような構成のスイッチ装置の場合、スライドピンに代えてシーソ部材を使用したので、部品点数を少なくすることができる。そして、シーソ部材の両端部の上面部に設けたばね手段を、シーソノブの下面部に常時当接させるように構成したので、異音が発生することを防止できる。
また、上記構成の場合、前記ばね手段を、前記シーソ部材に一体に設けたばね片部で構成することが好ましい。 In the case of the switch device having such a configuration, since the seesaw member is used in place of the slide pin, the number of parts can be reduced. And since the spring means provided in the upper surface part of the both ends of a seesaw member was comprised so that it may always contact | abut to the lower surface part of a seesaw knob, it can prevent that an abnormal noise generate | occur | produces.
Moreover, in the case of the said structure, it is preferable to comprise the said spring means with the spring piece part integrally provided in the said seesaw member.

以下、本発明の一実施例について、図１及び図２を参照しながら説明する。まず、図１に示すように、スイッチ装置２１は、基板２２と、基板２２上に設けられた２個のプッシュスイッチ２３、２４と、回動支点２５の周りに回動可能に設けられたシーソノブ２６と、回動支点２５よりも下方の回動支点２７の周りに回動可能に設けられたシーソ部材２８とを備えている。   An embodiment of the present invention will be described below with reference to FIGS. First, as shown in FIG. 1, the switch device 21 includes a substrate 22, two push switches 23 and 24 provided on the substrate 22, and a seesaw knob provided so as to be rotatable around a rotation fulcrum 25. 26 and a seesaw member 28 provided so as to be rotatable around a rotation fulcrum 27 below the rotation fulcrum 25.

上記シーソ部材２８は、全体として棒状をなし、その中間部分の肉厚部の下面部に溝部２８ａが形成され、両端部の下面部に押圧凸部２８ｂ、２８ｃが形成され、両端部の上面部にばね片部（ばね手段）２８ｄ、２８ｅが一体に形成されている。尚、シーソ部材２８は、例えばポリアセタード（ＰＯＭ）で形成されている。
そして、シーソ部材２８は、基板２２上におけるプッシュスイッチ２３、２４の中間部位に設けられた支持部材２９の支持凸部２９ａにシーソ部材２８の溝部２８ａを嵌合させることにより、回動可能に支持されている。この場合、シーソ部材２８の回動支点２７は、シーソノブ２６の回動支点２５よりも下方になるように構成されている。そして、シーソ部材２８は、シーソノブ２６とプッシュスイッチ２３、２４との間に配置されるように構成されている。 The seesaw member 28 has a rod-like shape as a whole, a groove portion 28a is formed on the lower surface portion of the thick portion at the middle portion thereof, pressing convex portions 28b and 28c are formed on the lower surface portions of both end portions, and upper surface portions on both end portions. The spring piece portions (spring means) 28d and 28e are integrally formed. The seesaw member 28 is made of, for example, polyacetate (POM).
The seesaw member 28 is rotatably supported by fitting the groove portion 28a of the seesaw member 28 to the support convex portion 29a of the support member 29 provided at the intermediate portion of the push switches 23 and 24 on the substrate 22. Has been. In this case, the rotation fulcrum 27 of the seesaw member 28 is configured to be lower than the rotation fulcrum 25 of the seesaw knob 26. The seesaw member 28 is configured to be disposed between the seesaw knob 26 and the push switches 23 and 24.

また、シーソノブ２６の両側壁部の中間部位には、軸部２６ａ（一方のみ図示）が突設されており、この軸部２６ａを支持部材（図示しない）に形成された軸受部に回動可能に嵌合させるように構成している。これにより、シーソノブ２６は回動支点２５の周りに回動可能な構成となっている。そして、シーソノブ２６の両端部の下面部には、シーソ部材２８の両端部の上面部を押圧する押圧凸部２６ｂ、２６ｃが突設されている。   Further, a shaft portion 26a (only one is shown) projects from an intermediate portion of both side wall portions of the seesaw knob 26, and the shaft portion 26a can be rotated to a bearing portion formed on a support member (not shown). It is comprised so that it may be fitted to. Thereby, the seesaw knob 26 is configured to be rotatable around the rotation fulcrum 25. Further, pressing convex portions 26 b and 26 c for pressing the upper surface portions of both end portions of the seesaw member 28 are provided on the lower surface portions of both end portions of the seesaw knob 26.

上記構成のスイッチ装置２１においては、図１に示すように、シーソ部材２８の上にシーソノブ２６を載せるようにして組み付けた状態では、シーソ部材２８のばね片部２８ｄ、２８ｅの先端部がシーソノブ２６の下面部に常時当接するように構成されている。そして、図２に示すように、シーソノブ２６（シーソ部材２８）を右回り方向（または左回り方向）に回動させたときでも、シーソ部材２８のばね片部２８ｄ、２８ｅの先端部はシーソノブ２６の下面部に当接するように構成されている。   In the switch device 21 having the above configuration, as shown in FIG. 1, in the state where the seesaw knob 26 is mounted on the seesaw member 28, the tip portions of the spring pieces 28 d and 28 e of the seesaw member 28 are at the seesaw knob 26. It is comprised so that it may always contact | abut to the lower surface part. As shown in FIG. 2, even when the seesaw knob 26 (seesaw member 28) is rotated in the clockwise direction (or counterclockwise direction), the tip portions of the spring pieces 28d and 28e of the seesaw member 28 remain at the seesaw knob 26. It is comprised so that it may contact | abut to the lower surface part.

尚、スイッチ装置２１の外郭は、例えばポリカーボネート（ＰＣ）製のケース３０で構成されている。
次に、上記構成のスイッチ装置２１の動作について説明する。シーソノブ２６の右端部を手指で下方へ押すと、図２に示すように、シーソノブ２６の押圧凸部２６ｂがシーソ部材２８を押し、このシーソ部材２８が回動する。これにより、シーソ部材２８の押圧部２２８ｂがプッシュスイッチ２３を押圧操作する。 The outer shell of the switch device 21 is constituted by a case 30 made of, for example, polycarbonate (PC).
Next, the operation of the switch device 21 configured as described above will be described. When the right end portion of the seesaw knob 26 is pushed downward with a finger, as shown in FIG. 2, the pressing convex portion 26b of the seesaw knob 26 pushes the seesaw member 28, and the seesaw member 28 rotates. Thereby, the pressing part 228b of the seesaw member 28 presses the push switch 23.

そして、シーソノブ２６の右端部から手指を離すと、プッシュスイッチ２３の復元力により、シーソ部材２８及びシーソノブ２６は元の位置（図１参照）へ戻る。このとき、シーソ部材２８のばね片部２８ｄ、２８ｅがシーソノブ２６の下面部に常時接触していることから、従来構成（図５及び図６参照）とは異なり、異音が発生することが無くなる。
また、上記実施例のスイッチ装置２１の場合、２個のスライドピンの代わりに１個のシーソ部材２８を使用する構成であるので、部品点数を少なくすることができ、組み付け工数が少なくなると共に、製造コストを安くすることができる。特に、上記実施例の場合、シーソ部材２８にばね片部２８ｄ、２８ｅを一体に形成したので、部品点数をより一層少なくすることができる。 When the finger is released from the right end of the seesaw knob 26, the seesaw member 28 and the seesaw knob 26 are returned to their original positions (see FIG. 1) by the restoring force of the push switch 23. At this time, since the spring pieces 28d and 28e of the seesaw member 28 are always in contact with the lower surface of the seesaw knob 26, unlike the conventional configuration (see FIGS. 5 and 6), no abnormal noise is generated. .
In the case of the switch device 21 of the above embodiment, since one seesaw member 28 is used instead of two slide pins, the number of parts can be reduced, and the number of assembling steps can be reduced. Manufacturing cost can be reduced. In particular, in the case of the above embodiment, the spring pieces 28d and 28e are integrally formed on the seesaw member 28, so that the number of parts can be further reduced.

尚、上記実施例においては、シーソ部材２８にばね片部２８ｄ、２８ｅを一体に形成したが、これに代えて、シーソ部材２８とシーソノブ２６との間に別体のばねを配設するように構成しても良い。この別体のばねとしては、図３及び図４に示すような板ばねでも良いし、他の形状の板ばねやコイルばね等でも良い。
ところで、従来構成として説明した図５及び図６に示すスイッチ装置１の場合、異音が発生するが、本発明のばね手段（ばね片部２８ｄ、２８ｅ）を使用せずに、異音をなくす方法があることはある。この方法について、具体的に説明すると、図６に示すように、シーソノブ６の右端部を手指で下方へ押すと、シーソ部材１３の左端部の上面部とシーソノブ６の押圧凸部６ｂとの間に隙間ができるが、この隙間をできるだけ小さくするように構成すれば良い。 In the above-described embodiment, the spring pieces 28d and 28e are integrally formed on the seesaw member 28. Instead, a separate spring is disposed between the seesaw member 28 and the seesaw knob 26. It may be configured. As this separate spring, a leaf spring as shown in FIGS. 3 and 4 may be used, or a leaf spring or a coil spring of another shape may be used.
By the way, in the case of the switch device 1 shown in FIG. 5 and FIG. 6 described as the conventional configuration, an abnormal noise is generated, but the abnormal noise is eliminated without using the spring means (spring pieces 28d and 28e) of the present invention. There is a way. This method will be described in detail. As shown in FIG. 6, when the right end portion of the seesaw knob 6 is pushed downward with a finger, the space between the upper surface portion of the left end portion of the seesaw member 13 and the pressing convex portion 6b of the seesaw knob 6 is obtained. However, the gap may be configured to be as small as possible.

そして、上記隙間を小さくする方法としては、シーソノブ６の押圧凸部６ａ、６ｂの突出高さを高くするように調整する方法がある。この調整方法を実行することにより、上記隙間をできるだけ小さく、すなわち、異音が発生しなくなるまで小さくすることができる。しかし、上記調整を完了するまでには、かなり長い時間を要すると共に、スイッチ装置１を構成する核部品の寸法精度を高くしたり、組み付け精度を高くしたりする必要もあり、大変面倒な方法であり、容易なことではなかった。   And as a method of making the said clearance gap small, there exists the method of adjusting so that the protrusion height of the press convex parts 6a and 6b of the seesaw knob 6 may be made high. By executing this adjustment method, the gap can be made as small as possible, that is, until no abnormal noise is generated. However, it takes a considerably long time to complete the adjustment, and it is necessary to increase the dimensional accuracy of the core parts constituting the switch device 1 or to increase the assembly accuracy. Yes, it was not easy.

これに対して、上記実施例によれば、部品点数を少なくすることができると共に、異音の発生を容易に防止することができる。   On the other hand, according to the above embodiment, the number of parts can be reduced and the generation of abnormal noise can be easily prevented.
