特開2010−80566号公報JP-A-2010-80566

近年、インターホン機器の小型化や薄型化が図られており、基板に関しても小型のものが採用されることになる。その結果、従来ではボタンの後方を略全て覆うように基板が存在していたところ、ボタンと基板とが前後で略重ならないようなものが出てきている。そして、そのようにボタンと基板とが前後で略重ならないとなると、一部(ボタンを本体ケースに対して保持する保持部等)が破損しているボタンを押し込み操作したような場合に、従来では基板が壁となって、ボタンの本体ケース内への落ち込みが抑制されていたところ、基板が壁となり得ず、ボタンが本体ケース内へ落ち込んでしまうという問題が生じてしまう。 In recent years, intercom devices have been made smaller and thinner, and smaller boards will be adopted. As a result, in the past, the substrate was present so as to cover almost the entire back of the button, but there are some that do not substantially overlap the button and the substrate in the front-rear direction. Then, when the button and the board do not substantially overlap each other in the front-rear direction, the conventional case where a button having a partially damaged part (such as a holding portion for holding the button against the main body case) is pushed in is operated. Then, when the substrate becomes a wall and the button is suppressed from falling into the main body case, the board cannot serve as a wall and the button falls into the main body case.

そこで、本発明は、上記問題に鑑みなされたものであって、基板の小型化に伴い、ボタンと基板とが前後で略重なっていなかったとしても、ボタンの一部が破損した際、ボタンが本体ケース内へ落ち込みにくいインターホン機器を提供しようとするものである。 Therefore, the present invention has been made in view of the above problems, and even if the button and the substrate are not substantially overlapped in the front-rear direction due to the miniaturization of the substrate, when a part of the button is damaged, the button is formed. The purpose is to provide an intercom device that does not easily fall into the main body case.

上記目的を達成するために、本発明は、本体ケースの前面にボタン窓が開設されているとともに、使用者が押し込み操作する操作部を有するボタンが、ボタン窓を介して操作部を本体ケースの前方へ突出させた状態で本体ケースに内蔵されたインターホン機器であって、ボタンが、操作部を有する操作部材と、本体ケース内に固定され、操作部材を本体ケース内で保持する保持部材と、操作部材と保持部材との間に介在される弾性部材とを備えているとともに、保持部材が、所定方向へ長い板状に成形されており、長手方向での一端を本体ケース内面にネジ止めし、他端を本体ケース内面と保持部材の後方に配される基板とにより前後から挟持して固定されることを特徴とする。 In order to achieve the above object, in the present invention, a button window is provided on the front surface of the main body case, and a button having an operation unit to be pushed and operated by the user makes the operation unit of the main body case through the button window. An intercom device built into the main body case in a state of being projected forward, and a button is an operation member having an operation unit, and a holding member fixed in the main body case to hold the operation member in the main body case. It is provided with an elastic member interposed between the operating member and the holding member, and the holding member is formed into a long plate shape in a predetermined direction, and one end in the longitudinal direction is screwed to the inner surface of the main body case. The other end is sandwiched and fixed from the front and back by the inner surface of the main body case and the substrate arranged behind the holding member.

本発明によれば、ボタンが、操作部を有する操作部材と、本体ケース内に固定され、操作部材を本体ケース内で保持する保持部材と、操作部材と保持部材との間に介在される弾性部材とを備えている。すなわち、操作部を有する操作部材を直接本体ケースに保持させるのではなく、操作部材と保持部材との2つの部材に分け、保持部材を介して保持させるようにしているため、従来破損していた箇所がそもそも破損しづらい。
また、保持部材が、所定方向へ長い板状に成形されており、長手方向での一端を本体ケース内面にネジ止めし、他端を本体ケース内面と保持部材の後方に配される基板とにより前後から挟持して固定されるため、ボタンにおける他端側さえ後方に基板が位置していれば、従来のようにボタンの破損時に基板が壁として機能しないような状況にあっても、ボタンの本体ケース内への落ち込みを効果的に抑制することができる。加えて、保持部材の固定に係る構成の簡素化を図ることができ、インターホン機器の小型化や薄型化を図ることができる。
According to the present invention, a button is fixed in an operating member having an operating portion, a holding member for holding the operating member in the main body case, and elasticity interposed between the operating member and the holding member. It is equipped with a member. That is, instead of directly holding the operating member having the operating portion on the main body case, the operating member is divided into two members, the operating member and the holding member, and the operating member is held via the holding member, which has been damaged in the past. The part is hard to break in the first place.
Further, the holding member is formed into a long plate shape in a predetermined direction, one end in the longitudinal direction is screwed to the inner surface of the main body case, and the other end is formed by the inner surface of the main body case and the substrate arranged behind the holding member. Since it is sandwiched and fixed from the front and back, if the board is located behind even the other end side of the button, even if the board does not function as a wall when the button is damaged as in the past, the button It is possible to effectively suppress the drop into the main body case. In addition, it is possible to simplify the configuration related to fixing the holding member, and it is possible to reduce the size and thickness of the intercom device.

ここで、本発明の要部となる報知ボタン8、及び報知ボタン8の取付構造について詳細に説明する。
報知ボタン8は、本体ケースの前面における表示部4の下方に設けられており、使用者に直接操作される操作部材11、操作部材11を保持する保持部材12、及び操作部材11と保持部材12との間に設置される弾性部材13を備えてなる。
Here, the notification button 8 which is a main part of the present invention and the mounting structure of the notification button 8 will be described in detail.
The notification button 8 is provided below the display unit 4 on the front surface of the main body case, and is an operating member 11 that is directly operated by the user, a holding member 12 that holds the operating member 11, and the operating member 11 and the holding member 12. It is provided with an elastic member 13 installed between and.

操作部材11は、前方へ膨出する操作部21と、操作部21から側方へ延設された遊挿部22と、操作部21における遊挿部22とは逆側に隣設された被係合部23とを有する合成樹脂製の部材である。操作部21は、正面視が左右方向へ長い矩形状に成形されており、前面が使用者により押し込み操作される操作面となっている。また、操作部21の後面で、左右方向における一方側の端部(長手方向における一方側の端部)には、基板3上に搭載されているスイッチ50をON/OFF操作するための操作突起24が後方へ突設されている。さらに、操作部21の後面で略中央となる箇所には、報知ボタン8の組み立て時に弾性部材13の前面に当接する当接リブ25が後方へ突設されている。 The operation member 11 includes an operation unit 21 that bulges forward, a play insertion unit 22 that extends laterally from the operation unit 21, and a cover that is adjacent to the side opposite to the play insertion unit 22 in the operation unit 21. It is a member made of synthetic resin having an engaging portion 23. The operation unit 21 is formed in a rectangular shape having a long front view in the left-right direction, and the front surface is an operation surface that is pushed in by the user. Further, on the rear surface of the operation unit 21, on one end in the left-right direction (one end in the longitudinal direction), an operation protrusion for turning on / off the switch 50 mounted on the substrate 3 24 is projected backward. Further, a contact rib 25 that comes into contact with the front surface of the elastic member 13 when the notification button 8 is assembled is projected rearward at a portion substantially centered on the rear surface of the operation unit 21.

遊挿部22は、操作部21における操作突起24が設けられている側の端部とは左右方向で反対側の端部から側方へ延設されている。そして、該遊挿部22には、前後方向へ貫通しており、報知ボタン8(特に保持部材12)を前ケース2の後面にネジ止めするための固定ネジ40を遊挿可能な遊挿孔が設けられている。被係合部23は、操作部21における操作突起24が設けられている側の端部から後方へ延設された舌状部であって、その内面(操作部21側の面)には、保持部材12の係合突起30が係合可能な係合凹部26が設けられている。 The free insertion portion 22 extends laterally from the end portion on the side opposite to the end portion of the operation portion 21 on which the operation protrusion 24 is provided in the left-right direction. A free insertion hole that penetrates the play insertion portion 22 in the front-rear direction and allows a fixing screw 40 for screwing the notification button 8 (particularly the holding member 12) to the rear surface of the front case 2 to be loosely inserted. Is provided. The engaged portion 23 is a tongue-shaped portion extending rearward from the end portion of the operating portion 21 on the side where the operating protrusion 24 is provided, and the inner surface thereof (the surface on the operating portion 21 side) has a surface. An engaging recess 26 is provided to which the engaging projection 30 of the holding member 12 can be engaged.

保持部材12は、操作部材11と同じく左右方向へ長い矩形板状に成形された弾性を有する合成樹脂製部材であって、上辺及び下辺に沿って前方へ起立する収容壁27が夫々設けられており、上下の収容壁27、27間に操作部材11を収容可能となっている。また、保持部材12の前面において、操作部材11を収容した際に当接リブ25と対向する位置には、弾性部材13を設置可能な設置部28が設けられている。さらに、保持部材12の左右方向における一方側の端部には、操作突起24を挿通可能な操作窓29が穿設されているとともに、操作部材11を収容した際に係合凹部26に係合可能な係合突起30が、上下の収容壁27、27を超えて更に側方へ突設されている。加えて、保持部材12の左右方向における他方側の端部には、保持部材12を前ケース2の後面にネジ止めするためのネジ孔を有する固定部31が設けられている。 The holding member 12 is an elastic synthetic resin member formed in a rectangular plate shape that is long in the left-right direction like the operating member 11, and is provided with accommodating walls 27 that stand forward along the upper and lower sides, respectively. The operating member 11 can be accommodated between the upper and lower accommodating walls 27 and 27. Further, on the front surface of the holding member 12, an installation portion 28 on which the elastic member 13 can be installed is provided at a position facing the contact rib 25 when the operating member 11 is accommodated. Further, an operation window 29 through which the operation protrusion 24 can be inserted is formed at one end of the holding member 12 in the left-right direction, and when the operation member 11 is accommodated, it engages with the engagement recess 26. Possible engaging projections 30 project further laterally beyond the upper and lower accommodation walls 27, 27. In addition, a fixing portion 31 having a screw hole for screwing the holding member 12 to the rear surface of the front case 2 is provided at the other end of the holding member 12 in the left-right direction.

一方、前ケース2には、操作部材11の操作部21と略同形状とされたボタン窓41、41が開設されている。また、各ボタン窓41の左右方向で外側となる位置には、固定ネジ40をねじ込むことで、報知ボタン8をネジ止めするための固定ボス42が後方へ突設されている。 On the other hand, the front case 2 is provided with button windows 41 and 41 having substantially the same shape as the operation unit 21 of the operation member 11. Further, a fixing boss 42 for screwing the notification button 8 is projected rearward at a position outside of each button window 41 in the left-right direction by screwing a fixing screw 40.

そして、上述したような構成を有する報知ボタン8の本体ケースへの取り付けについて説明すると、まず操作部材11の操作部21がボタン窓41を介して前ケース2の前方へ突出するように、前ケース2の後面側に操作部材11を配置する。この配置に際しては、左右どちらの操作部材11においても、被係合部23側が左右方向で内側に、遊挿部22側が左右方向で外側に位置するような姿勢とする。次に、弾性部材13を保持部材12の設置部28に設置した後、係合突起30を係合凹部26に係合させながら、操作突起24を操作窓29内に位置させつつ収容壁27、27間に操作部材11を収容させて、操作部材11の後側から保持部材12を組み付ける。最後に、固定ネジ40により保持部材12の固定部31を前ケース2の固定ボス42にネジ止めすれば、報知ボタン8の取り付けは完了となる。なお、各報知ボタン8における被係合部23側の端部はネジ止め等されていないものの、報知ボタン8、8の後方に基板3を設置することで、被係合部23側の端部も、前ケース2内面と基板3前面とにより前後から挟持される格好で固定されることになる(図7)。 Then, to explain the attachment of the notification button 8 having the above-described configuration to the main body case, first, the front case so that the operation unit 21 of the operation member 11 projects to the front of the front case 2 through the button window 41. The operation member 11 is arranged on the rear surface side of 2. In this arrangement, both the left and right operating members 11 are arranged so that the engaged portion 23 side is located inside in the left-right direction and the free insertion portion 22 side is located outside in the left-right direction. Next, after the elastic member 13 is installed in the installation portion 28 of the holding member 12, the accommodating wall 27, while engaging the engaging protrusion 30 with the engaging recess 26 and positioning the operating protrusion 24 in the operation window 29, The operating member 11 is accommodated between 27, and the holding member 12 is assembled from the rear side of the operating member 11. Finally, if the fixing portion 31 of the holding member 12 is screwed to the fixing boss 42 of the front case 2 with the fixing screw 40, the attachment of the notification button 8 is completed. Although the end portion of each notification button 8 on the engaged portion 23 side is not screwed or the like, by installing the substrate 3 behind the notification buttons 8 and 8, the end portion on the engaged portion 23 side is provided. Also, the inner surface of the front case 2 and the front surface of the substrate 3 are fixed so as to be sandwiched from the front and back (FIG. 7).

上述したようにして取り付けられた各報知ボタン8では、操作部21が押し込み操作されると、弾性部材13が変形して操作部材11が後方へ移動し、操作突起24によりスイッチ50が操作される。一方、操作部21に対する押し込み方向への負荷が解除されると、弾性部材13の弾性力によって操作部材11は押し込み操作前の位置まで復帰する。 In each of the notification buttons 8 attached as described above, when the operation unit 21 is pushed in, the elastic member 13 is deformed and the operation member 11 moves rearward, and the switch 50 is operated by the operation protrusion 24. .. On the other hand, when the load on the operating portion 21 in the pushing direction is released, the operating member 11 returns to the position before the pushing operation due to the elastic force of the elastic member 13.

また、上述したようにして取り付けられた報知ボタン8、8の後方に、インターホン親機1の主たる動作(たとえばインターホン子機との間での通話動作や映像の送受信動作等)を制御する基板3が設置されることになるが、当該基板3は、インターホン親機1の薄型化を実現すべく出来る限り小型に成形されている。そして、本実施例に係る基板3では、報知ボタン8、8の後方となる箇所が大きく切り欠かれており、各報知ボタン8の左右方向で内側半分程度にしか基板3は位置していない。したがって、従来のように報知ボタン8の操作部が直接本体ケースに保持されているような構造であると、当該保持部が破損等した際に、後方に基板3が位置していないが故、報知ボタン8が本体ケース内に落ち込んでしまうことになる。しかしながら、本実施例に係る構造では、報知ボタン8の本体ケースへの保持に係り、操作部材11を保持部材12に保持させるという構成を採用しており、操作部材11を本体ケースに直接保持させていないため、そもそも保持部(固定部31等)が破損しづらい構造になっている。その上、たとえ保持部が破損したとしても、左右方向で内側の端部が前ケース2内面と基板3前面とにより前後から挟持されている保持部材12によって、操作部材11は支えられているため、報知ボタン8の本体ケース内への落ち込みも抑制することができる。 Further, behind the notification buttons 8 and 8 attached as described above, the substrate 3 that controls the main operation of the intercom master unit 1 (for example, a call operation with the intercom slave unit, a video transmission / reception operation, etc.). However, the substrate 3 is molded as small as possible in order to reduce the thickness of the intercom master unit 1. In the substrate 3 according to the present embodiment, the portion behind the notification buttons 8 and 8 is largely cut out, and the substrate 3 is located only about the inner half in the left-right direction of each notification button 8. Therefore, if the structure is such that the operation portion of the notification button 8 is directly held by the main body case as in the conventional case, the substrate 3 is not located behind when the holding portion is damaged or the like. The notification button 8 will fall into the main body case. However, in the structure according to the present embodiment, a configuration is adopted in which the operation member 11 is held by the holding member 12 in relation to the holding of the notification button 8 in the main body case, and the operation member 11 is directly held by the main body case. Since the holding portion (fixed portion 31 or the like) is not easily damaged in the first place. Moreover, even if the holding portion is damaged, the operating member 11 is supported by the holding member 12 whose inner end portion is sandwiched from the front and back by the inner surface of the front case 2 and the front surface of the substrate 3 in the left-right direction. , The drop of the notification button 8 into the main body case can also be suppressed.

以上のような構成を有するインターホン親機1によれば、報知ボタン8が、操作部21を有する操作部材11と、前ケース2の後面に固定され、操作部材11を本体ケース内で保持する保持部材12と、操作部材11と保持部材12との間に介在される弾性部材13とを備えている。すなわち、従来のように操作部材11を本体ケースに直接保持させるのではなく、操作部材11と保持部材12との2つの部材に分け、保持部材12を介して保持させるように構成しているため、そもそも報知ボタン8の保持部が破損しづらい。 According to the intercom master unit 1 having the above configuration, the notification button 8 is fixed to the operation member 11 having the operation unit 21 and the rear surface of the front case 2, and holds the operation member 11 in the main body case. A member 12 and an elastic member 13 interposed between the operating member 11 and the holding member 12 are provided. That is, the operating member 11 is not directly held by the main body case as in the conventional case, but is divided into two members, the operating member 11 and the holding member 12, and is held via the holding member 12. In the first place, the holding portion of the notification button 8 is hard to be damaged.

また、保持部材12が、左右方向へ長い矩形板状に成形されており、左右方向で外側の端部を前ケース2の後面にネジ止めするとともに、左右方向で内側の端部を前ケース2の後面と保持部材12の後方に配される基板3とにより前後から挟持して固定されるため、報知ボタン8における左右方向で内側の端部の後方にさえ基板3が位置していれば、従来のようにボタンの破損時に基板3が壁として機能しないような状況にあっても、報知ボタン8の本体ケース内への落ち込みを効果的に抑制することができる。加えて、保持部材12の固定に係る構成の簡素化を図ることができ、インターホン親機1の小型化や薄型化を図ることができる。 Further, the holding member 12 is formed into a rectangular plate shape that is long in the left-right direction, and the outer end portion is screwed to the rear surface of the front case 2 in the left-right direction, and the inner end portion is screwed to the rear surface of the front case 2 in the left-right direction. Since it is sandwiched and fixed from the front and back by the rear surface and the substrate 3 arranged behind the holding member 12, if the substrate 3 is located even behind the inner end portion in the left-right direction of the notification button 8. Even in a situation where the substrate 3 does not function as a wall when the button is damaged as in the conventional case, it is possible to effectively suppress the notification button 8 from falling into the main body case. In addition, the configuration for fixing the holding member 12 can be simplified, and the intercom master unit 1 can be made smaller and thinner.

なお、本発明に係るインターホン機器は、インターホン機器の全体的な構成は勿論、ボタンに係る構成等についても、本発明の趣旨を逸脱しない範囲で必要に応じて適宜変更することができる。 In the intercom device according to the present invention, not only the overall configuration of the intercom device but also the configuration related to the buttons and the like can be appropriately changed as necessary without departing from the spirit of the present invention.

たとえば,上記実施形態では、本発明を報知ボタンについて採用しているが、応答ボタンを始めとして、他のボタンについても好適に採用可能であることは言うまでもない。
また、上記実施形態では、左右方向へ長いボタンについて説明しているが、上下方向若しくは傾斜方向へ長いボタンとして成形することも可能である。
さらに、ボタンにおける長手方向でのどちら側の端部をネジ止めするかについても適宜設計変更可能であって、上記実施形態のものにおいて、左右方向で内側の端部をネジ止めし、外側の端部を前後から挟持するように構成することは可能である。
加えて、上記実施形態ではインターホン親機について説明しているが、本発明は、押し込み操作するボタンさえ備えていれば、インターホン子機や集合玄関機等の他のインターホン機器についても好適に採用することができる。
For example, in the above embodiment, the present invention is adopted for the notification button, but it goes without saying that other buttons such as the response button can also be suitably adopted.
