特開２００５−４５７０４号公報JP 2005-45704 A

上記特許文献１のように、ボタン操作によりケース内に組み込まれているスイッチ素子をオン／オフする構成の場合、スイッチ素子押下弾性片が、押下された通話ボタンを復帰させる弾性作用を奏するよう構成されている。
ところが、このスイッチ素子押下弾性片のように、弾性を備えたスイッチ操作部材は、合成樹脂製であり、通常は機器ケースに一体に形成される。そのため、成形によって発生するウエルドラインの影響等により、予想していない箇所で折れることがあり、折れた場合はスイッチ素子を押下する部材が無くなってしまうため、通話ボタンを押下してもスイッチ素子がオン動作しなくなってしまう問題があった。 In the case where the switch element incorporated in the case is turned on / off by the button operation as in Patent Document 1, the switch element pressing elastic piece has an elastic action for returning the pressed call button. Has been.
However, the switch operating member having elasticity like the switch element pressing elastic piece is made of synthetic resin and is usually formed integrally with the device case. Therefore, it may break at an unexpected part due to the influence of the weld line generated by molding, etc., and if it breaks, there will be no member to press the switch element. There was a problem that it could not be turned on.

そこで、本発明はこのような問題点に鑑み、ケースに一体に形成されたスイッチ操作部材が折れても操作ボタンの機能を維持できる電子機器の操作ボタン構造を提供することを目的としている。   In view of the above problems, an object of the present invention is to provide an operation button structure for an electronic device that can maintain the function of the operation button even when a switch operation member formed integrally with the case is broken.

上記課題を解決する為に、請求項１の発明は、押下操作を受けてケース内に設けられたスイッチ素子をオン／オフする電子機器の操作ボタン構造であって、ケース上に配置され、押下操作する操作面が形成されたボタン部材と、ボタン部材の背部であってスイッチ素子に近接して配置され、ボタン部材の押下操作を受けてスイッチ素子に当接してオン／オフさせるスイッチ操作部材とを有し、スイッチ操作部材は、ケースに一体に形成されてボタン部材を復帰させる弾性を有すると共に、ボタン部材との間で凹部と突起とが嵌合する係合部を有し、スイッチ操作部材がケースから分離して弾性機能を失った状態でも、ボタン部材との係合が維持され、スイッチ操作部材のスイッチ素子に当接する部位が保持されることを特徴とする。
この構成によれば、スイッチ操作部材に不慮のストレスが加わって折れてしまっても、凹部と突起との係合状態は維持されるため、引き続きボタン部材の操作でスイッチ素子のオン／オフを継続して実施でき、操作ボタンの機能が失われるのを防止できる。 In order to solve the above-mentioned problem, the invention of claim 1 is an operation button structure of an electronic device that turns on / off a switch element provided in a case in response to a pressing operation, and is disposed on the case and pressed. A button member on which an operation surface to be operated is formed; a switch operation member which is disposed behind the button member and in proximity to the switch element; The switch operating member is formed integrally with the case and has elasticity to return the button member, and has an engaging portion in which the recess and the protrusion fit between the button member, and the switch operating member Even if it is separated from the case and loses its elastic function, the engagement with the button member is maintained, and the portion of the switch operating member that contacts the switch element is held.
According to this configuration, even if the switch operating member is bent due to unexpected stress, the engagement state between the recess and the protrusion is maintained, so that the switch element is continuously turned on / off by operating the button member. It is possible to prevent the loss of the function of the operation button.

請求項２の発明は、請求項１に記載の構成において、係合部が、スイッチ操作部材に形成した凹部と、ボタン部材に形成した突起とから成り、スイッチ操作部材のスイッチ素子に当接する部位には、スイッチ素子を押下するためのリブが形成され、凹部はリブの背部にリブより小さい径で形成されて成ることを特徴とする。
この構成によれば、リブを設けて厚く形成されたスイッチ操作部材の背部に凹部が形成されるため、凹部を設けてもスイッチ操作部材の強度が低下することがない。また、スイッチ素子上に配置されるリブが位置決めされてスイッチ操作部材が保持されるため、スイッチ操作部材が折れても安定した押下操作を実現できる。 According to a second aspect of the present invention, in the configuration according to the first aspect, the engaging portion includes a recess formed in the switch operating member and a protrusion formed in the button member, and a portion that contacts the switch element of the switch operating member. Is characterized in that a rib for pressing the switch element is formed, and the recess is formed on the back of the rib with a diameter smaller than the rib.
According to this configuration, since the concave portion is formed on the back portion of the switch operating member that is formed thick by providing the rib, the strength of the switch operating member does not decrease even if the concave portion is provided. Further, since the rib arranged on the switch element is positioned and the switch operation member is held, a stable pressing operation can be realized even if the switch operation member is broken.

本発明によれば、スイッチ操作部材に不慮のストレスが加わり折れてしまっても、凹部と突起との係合状態が維持されるため、引き続きボタン部材の操作でスイッチ素子のオン／オフを継続して実施でき、操作ボタンの機能が失われるのを防止できる。   According to the present invention, even if unexpected stress is applied to the switch operation member and it is bent, the engagement state between the recess and the projection is maintained, so that the switch element is continuously turned on / off by the operation of the button member. It is possible to prevent the operation button from being lost.

これらの操作ボタンのうち、ケース１０の下部に設けられたモニタボタン３、通話ボタン４、終了ボタン５の３つが本発明の操作ボタン構造を有している。 The intercom base unit 1 has a display 2 for displaying a captured image of a camera provided in the entrance handset on the front surface of the case 10 and a monitor button 3 for performing a display operation of the image (the button member 11 to be pressed is removed). Operation buttons such as a call button 4 for carrying out a call, an end button 5 for ending the call, and a menu display button 6 for switching the display 2 are provided.
Of these operation buttons, three of the monitor button 3, the call button 4, and the end button 5 provided at the lower part of the case 10 have the operation button structure of the present invention.

図２は図１のＡ部を拡大した図であり、操作ボタンの構造を示している。図２に示すように、操作ボタンであるモニタボタン３の形成部はボタン部材１１で閉塞されるボタン開口部７を有し、ボタン開口部７の内部には、ボタン部材１１の押下によりオン／オフ動作するスイッチ素子１２、スイッチ素子１２の前面を覆うようにケース１０と一体に形成された弾性片１５が設けられている。   FIG. 2 is an enlarged view of part A in FIG. 1 and shows the structure of the operation buttons. As shown in FIG. 2, the formation portion of the monitor button 3 that is an operation button has a button opening 7 that is closed by the button member 11, and the button opening 7 is turned on / off by pressing the button member 11. The switch element 12 that is turned off, and an elastic piece 15 that is formed integrally with the case 10 so as to cover the front surface of the switch element 12 are provided.

弾性片１５は、押下したボタン部材１１を復帰させるための部材であり、復帰専用の２つの成形バネ１３と、スイッチ素子１２に当接してオン／オフを操作するスイッチ操作部材１４とで構成され、スイッチ操作部材１４はスイッチ素子１２の前面に配置され、その左右に成形バネ１３が並設されている。
これらはケース１０を壁面に設置した状態でケース構成部材から垂下するように下方に向けて延設されている。そして、スイッチ操作部材１４は、上下に延びて弾性を有する左右の帯片１４ａと、帯片１４ａの下部同士を連結する連結片１４ｂとから成り、略コ字状を成している。 The elastic piece 15 is a member for returning the pressed button member 11 and is composed of two molding springs 13 dedicated to the return and a switch operation member 14 that abuts on the switch element 12 and operates on / off. The switch operating member 14 is disposed on the front surface of the switch element 12, and molding springs 13 are arranged in parallel on the left and right sides thereof.
These are extended downward so as to hang down from the case constituent member with the case 10 installed on the wall surface. The switch operating member 14 is composed of left and right strips 14a that extend vertically and has elasticity, and a connecting piece 14b that connects the lower portions of the strip 14a, and has a substantially U-shape.

図３は図２に示す操作ボタンの中央部を縦方向に切断したインターホン親機１の断面説明図を示している。この図３に示すように、ケース１０内部には回路基板１６がケース１０前面に略平行に配置され、この回路基板１６にモニタボタン３のスイッチ素子１２を始め、通話ボタン４、終了ボタン５のスイッチ素子（図示せず）が搭載されている。また、インターホン機能を実現するための他の電子部品も合わせて搭載されている。
そして、スイッチ操作部材１４の連結片１４ｂの裏面には、スイッチ素子１２の上部であって近接した部位に、当接してスイッチ素子１２をオン／オフ操作する十字状のリブ１７が形成されている。
一方、スイッチ操作部材１４の反対側の前面には、後述するボタン部材１１に形成された突起１１ａが挿入されて嵌合する孔状の凹部１８が形成されている。 FIG. 3 is a cross-sectional explanatory view of the intercom base unit 1 in which the central portion of the operation button shown in FIG. 2 is cut in the vertical direction. As shown in FIG. 3, a circuit board 16 is arranged in the case 10 substantially parallel to the front surface of the case 10, and the switch button 12 of the monitor button 3, the call button 4, and the end button 5 A switch element (not shown) is mounted. In addition, other electronic components for realizing the intercom function are also mounted.
Further, on the back surface of the connecting piece 14b of the switch operation member 14, a cross-shaped rib 17 is formed on the switch element 12 in the vicinity of the switch element 12 so that the switch element 12 is turned on and off. .
On the other hand, a hole-like recess 18 into which a protrusion 11a formed on a button member 11 described later is inserted and fitted is formed on the front surface on the opposite side of the switch operation member 14.

図４はボタン部材１１を背部から見た斜視図であり、図４に示すように上部にケース１０に係合してボタン部材１１を押下操作する際の回動中心となるヒンジ部２０が突設されている。また、ケース１０に組み付けた状態でスイッチ操作部材１４に形成された凹部１８に嵌合する突起１１ａが背面中央下部に形成されている。尚、ボタン部材１１の押下操作される前面は、図１に示すように平坦な面で形成されている。   FIG. 4 is a perspective view of the button member 11 as viewed from the back. As shown in FIG. 4, the hinge portion 20 that is the center of rotation when the button member 11 is pushed down by engaging the case 10 at the top projects. It is installed. Further, a protrusion 11a that fits into a recess 18 formed in the switch operation member 14 in a state assembled to the case 10 is formed at the lower center of the back surface. Note that the front surface where the button member 11 is pressed is formed as a flat surface as shown in FIG.

このように構成された操作ボタンの作用は以下のようである。但し、スイッチ操作部材１４の作用を中心に説明する。ボタン部材１１のヒンジ部２０をケース１０裏面の図示しない所定部位に嵌合してボタン部材１１をケース１０に取り付けると、ボタン部材１１の突起１１ａがスイッチ操作部材１４の凹部１８に嵌合する。この結果、ボタン部材１１は上部ヒンジ部２０の連結に加えて下部も位置決めされ、良好に保持される。   The operation of the operation button configured as described above is as follows. However, the operation of the switch operation member 14 will be mainly described. When the button member 11 is attached to the case 10 by fitting the hinge portion 20 of the button member 11 to a predetermined portion (not shown) on the back surface of the case 10, the protrusion 11 a of the button member 11 is fitted into the recess 18 of the switch operation member 14. As a result, in addition to the connection of the upper hinge portion 20, the lower portion of the button member 11 is positioned and held well.

この状態で、ボタン部材１１を押下すれば、スイッチ素子１２に近接した状態で配置されているスイッチ操作部材１４が内部のスイッチ素子１２をオンさせる。また、ボタン部材１１の押下を止めれば成形バネ１３等の弾性片１５の作用で復帰動作し、スイッチ素子１２はオフ動作する。
そして、何らかの強い外力が加わったことによりスイッチ操作部材１４が折れた場合、突起１１ａと凹部１８との嵌合状態は維持され、容易に外れない。そのため、スイッチ操作部材１４の上部に位置ズレが発生したとしても、突起１１ａと係合しているリブ１７は位置ズレを起こすことがなく、ボタン部材１１の押下をスイッチ素子１２に伝達し、スイッチ素子１２を操作できる。 When the button member 11 is pressed in this state, the switch operating member 14 disposed in the state of being close to the switch element 12 turns on the internal switch element 12. If the pressing of the button member 11 is stopped, the return operation is performed by the action of the elastic piece 15 such as the molding spring 13 and the switch element 12 is turned off.
When the switch operation member 14 is broken by applying some strong external force, the fitting state between the protrusion 11a and the recess 18 is maintained and cannot be easily removed. Therefore, even if a positional deviation occurs in the upper part of the switch operating member 14, the rib 17 engaged with the protrusion 11a does not cause a positional deviation, and the pressing of the button member 11 is transmitted to the switch element 12, and the switch The element 12 can be operated.

このように、スイッチ操作部材１４に不慮のストレスが加わって折れてしまっても、凹部１８と突起１１ａとの係合状態は維持されるため、引き続きボタン部材１１の操作でスイッチ素子１２のオン／オフを継続して実施でき、操作ボタンの機能が失われるのを防止できる。
また、リブ１７を設けて厚く形成されたスイッチ操作部材１４の背部に凹部１８が形成されるため、凹部１８を設けてもスイッチ操作部材１４の強度が低下することがない。また、スイッチ素子１２上に配置されるリブ１７が、突起１１ａにより位置決めされてスイッチ操作部材１４が保持されるため、スイッチ操作部材１４が折れても安定した押下操作を実現できる。 As described above, even if the switch operating member 14 is bent due to an unexpected stress, the engagement state between the recess 18 and the protrusion 11a is maintained. It can be turned off continuously, and the function of the operation button can be prevented from being lost.
Moreover, since the recessed part 18 is formed in the back part of the switch operation member 14 formed thickly by providing the rib 17, even if the recessed part 18 is provided, the intensity | strength of the switch operation member 14 does not fall. Further, since the rib 17 arranged on the switch element 12 is positioned by the protrusion 11a and the switch operation member 14 is held, a stable pressing operation can be realized even if the switch operation member 14 is broken.

尚、上記実施形態は、ボタン部材１１が比較的大きい形状であるため、スイッチ操作部材１４以外に弾性片１５として成形バネ１３を左右に配置しているが、ボタン部材１１が小さければ左右の成形バネ１３は無くても良い。スイッチ操作部材１４の弾性力だけでも復帰力を発生できるし、全ての弾性片１５が折れた場合でも、スイッチ素子１２自身の復帰力によりリブ１７が位置ズレを起こさない限り、オン／オフ操作は可能である。
また、スイッチ操作部材１４に凹部１８を設け、ボタン部材１１に凹部１８に嵌合する突起１１ａを設けたが、凹部１８と突起１１ａは逆に配置しても良い。 In the above embodiment, since the button member 11 has a relatively large shape, the molding springs 13 are arranged on the left and right as the elastic pieces 15 in addition to the switch operation member 14. The spring 13 may be omitted. The return force can be generated only by the elastic force of the switch operating member 14, and even when all the elastic pieces 15 are broken, the ON / OFF operation is not performed unless the rib 17 is displaced due to the return force of the switch element 12 itself. Is possible.
Further, although the switch operating member 14 is provided with the recess 18 and the button member 11 is provided with the protrusion 11a that fits into the recess 18, the recess 18 and the protrusion 11a may be arranged in reverse.

上記実施形態では、インターホン機器１を一例として説明したが、本発明の操作ボタン構造は、内部に設けたスイッチ素子をケース上に設けたボタン部材１１で操作する構成の電子機器に対して幅広く適用できるものである。   In the above embodiment, the interphone device 1 has been described as an example. However, the operation button structure of the present invention is widely applied to electronic devices having a configuration in which a switch element provided inside is operated by a button member 11 provided on a case.
