Description

【0001】
【発明の属する技術分野】
この発明は、スイッチ,コンセント等の配線器具を建築構造物の壁面に取り付けるために用いられる配線器具取付装置に関し、特に火災の延焼を抑制する耐火プレートを備えた配線器具取付装置に関する。
【0002】
【従来の技術】
図9は、従来のこの種の配線器具取付装置を示す斜視図である。
同図に示す従来の配線器具取付装置は、取付枠10、化粧プレート20、および耐火プレート30を備えている。
【0003】
取付枠10は、建築構造物の壁面に固定され、スイッチ,コンセント等の配線器具を装着するための部材である。化粧プレート20は、取付枠10に係合して同枠10の表面を被覆するための部材である。そして、耐火プレート30は、取付枠10と化粧プレート20との間に介在して設けられ、火災発生時に炎が壁内空間へ進出し延焼するのを抑制するための部材である。
【0004】
さて、上述した機能を有する取付枠10には、固定用孔13、装着孔11、操作孔12など各種の孔が穿設してある。このうち、固定用孔13は、取付枠10を壁面にねじ止めして固定する際に用いられる。
装着孔11は取付枠10の中央部に穿設してあり、配線器具のボス部が挿通される。この装着孔11の周縁部裏面側には、図示されていないが、配線器具を係止するための係止部が形成してある。この係止部に配線器具側の係止爪を係合させることで、配線器具を取付枠に装着することができる。
操作孔12は、装着孔11の周囲に穿設してある。この操作孔12にドライバ等の工具を差し込み、上述した係止部と配線器具側の係止爪との間の係合状態を解除して、配線器具を取付枠から取り外すことができるようになっている。
【0005】
さらに、取付枠10には、化粧プレート20および耐火プレート30を装着するための係合孔15,16がそれぞれ別個に穿設してある。化粧プレート用の係合孔15には、化粧プレート20の裏面に形成した係合爪(図示せず)が係合して、化粧プレート20を取付枠10の表面側に装着する。また、耐火プレート用の係合孔16には、耐火プレート30の周縁部に形成した係合爪33が係合して、耐火プレート30を取付枠10の表面側に装着する。
【0006】
このような構成の従来の配線器具取付装置は、作業現場において所要の配線器具を取付枠10に装着した後、該取付枠10を壁面に固定する。次いで、耐火プレート30を取付枠10に装着してから、最後に化粧プレート20を取付枠10に装着して施工を完了する。
【0007】
【発明が解決しようとする課題】
上述したように従来の配線器具取付装置は、取付枠10に固定用孔13、装着孔11、操作孔12のみならず、化粧プレート用の係合孔15および耐火プレート用の係合孔16がそれぞれ別個に穿設されていた。このような各種の孔を穿設した場合、必然的に取付枠10の強度が低下していく。このため、従来は取付枠10の裏面に、複雑な形状の補強リブを形成して所要の強度を確保していた。ゆえに、複雑形状の金型を必要とするなど製作コストが高価格となり、しかも不良品率が高く歩留りが悪いという問題があった。
【0008】
また、上述した作業現場における配線器具取付作業の手順から明らかなように、従来の配線器具取付装置は、耐火プレート30と化粧プレート20をそれそれ別個に装着する構造となっていたので、耐火プレート30を備えない配線器具取付装置に比べて作業工数が多い。さらに、取付枠10、化粧プレート20、および耐火プレート30をそれぞれ分解して輸送しなければならず、輸送時の取扱いが煩雑であった。
【0009】
この発明は、このような事情に鑑みてなされたもので、取付枠10の形状を簡素化しつつ同枠10の強度を増強することを目的とする。
また、この発明は、作業現場における配線器具の取付け作業工数を減らして、作業性の向上を図ることができ、しかも輸送時の取扱いを容易化できる配線器具取付装置の提供を目的とする。
【0010】
【課題を解決するための手段】
上記目的を達成するためにこの発明は、壁面に固定される取付枠と、該取付枠の表面を被覆するとともに配線器具のボス部を露出させる窓部を備えた化粧プレートと、取付枠と化粧プレートとの間に介在して設けられる耐火プレートとを含む配線器具取付装置において、取付枠に、化粧プレートおよび耐火プレートを装着するための装着部を形成するとともに、化粧プレートおよび耐火プレートに、取付枠の装着部と係合する係合手段をそれぞれ形成したことを特徴としている。
【0011】
このような構成とすることで、取付部に形成した装着部に対し、化粧プレートおよび耐火プレートを一括して係合することができる。したがって、例えば、取付枠の装着部を上記係合手段と係合する孔形状に形成した場合であっても、化粧プレートおよび耐火プレートに対し別個に孔(装着部)を形成する構造に比べ孔の穿設箇所が減少するため、強度が増強する。
その結果、補強用のリブを複雑に形成する必要がなく、構造の簡素化ひいては製作コストの低価格化および歩留りの向上を図ることができる。
【0012】
この発明は、化粧プレートおよび耐火プレートに形成した各係合手段に、それぞれ相互に係合する係合部を設けてもよい。
このように構成すれば、工場出荷時に化粧プレートと耐火プレートを相互に係合して一体化しておくことができ、各構成部材を分けて梱包する場合に比べ、輸送時の取扱いが容易となる。しかも、あらかじめ係合させた化粧プレートと耐火プレートを一括して取付枠に装着できるので、取付け作業工数が減り作業性の向上を図ることができる。
【0013】
【発明の実施の形態】
以下、この発明の実施の形態について図面を参照して詳細に説明する。
図1〜図8はこの発明の実施形態を説明するための図であり、図1は配線器具取付装置の分解斜視図である。図2は同装置の化粧プレートを示す斜視図、図3は同装置の耐火プレートを示す斜視図である。
【0014】
図1に示すように、この実施形態に係る配線器具取付装置は、取付枠10、化粧プレート20、および耐火プレート30を備えている。
取付枠10は、建築構造物の壁面に固定され、スイッチ,コンセント等の配線器具を装着するための部材である。この取付枠10の中央部には、装着孔11が形成してあり、この装着孔11にスイッチ,コンセント等の配線器具におけるボス部が挿通される。装着孔11の両側縁部裏面側には、配線器具を係止するための係止段部(図示せず)が形成してあり、該係止段部に配線器具の係止爪を係止することで、取付枠10へ配線器具を装着することができる。
【0015】
装着孔11の両側縁部には、係止段部へと貫通する操作孔12が形成してある。この操作孔12にドライバ等の工具を差し込むことにより、係止段部と配線器具の係止爪との間の係止状態を解除して、配線器具を取付枠10から取り外すことができる。
取付枠10の上下端部付近には、壁面への固定用孔13が形成してある。これらの固定用孔13は、取付枠10を壁面にねじ止めして固定する際に用いられる。
なお、取付枠10における上述した配線器具の着脱構造、および壁面への固定構造については、従来から公知の構造を適用してもよい。
【0016】
化粧プレート20は、取付枠10の表面を被覆するための部材である。この化粧プレート20の中央部には窓部21が形成してあり、取付枠10に装着した配線器具のボス部をこの窓部21から露出させる。
図7は配線器具取付装置にスイッチを装着した状態を示す外観斜視図であり、図8は同じくコンセントを装着した状態を示す外観斜視図である。
これらの図に示すように、取付枠10は化粧プレート20により被覆され、スイッチ1やコンセント2のボス部1a,2aのみが窓部21から露出する。
【0017】
耐火プレート30は、取付枠10と化粧プレート20との間に介在して設けられ、火災発生時に炎が壁内空間へ進出し延焼するのを抑制するための部材であり、この実施形態ではステンレス板により形成してある。この耐火プレート30の中央部にも、取付枠10に装着した配線器具のボス部を挿通するための透孔31が形成してある。
【0018】
上述した取付枠10には、化粧プレート20および耐火プレート30を装着するための係合孔(装着部)14が所定箇所に設けてある。一方、化粧プレート20には、鉤形状の係合爪(係合手段)22が形成してある(図2参照)。この係合爪22は、取付枠10に設けた係合孔14の縁部に係合して、化粧プレート20を取付枠10の表面側に固定する。
さらに、耐火プレート30には係合片(係合手段)32が形成してある(図3参照)。この係合片32も、取付枠10に設けた係合孔14の縁部に係合して、耐火プレート30を取付枠10の表面側に固定する。ここで、耐火プレート30に形成した係合片32の正面形状は、化粧プレート20に形成した係合爪22と略同じ鉤形状に成形してある。
【0019】
上記のように、化粧プレート20に形成した係合爪22と、耐火プレート30に形成した係合片32とを、ともに取付枠10に設けた係合孔14の縁部に係合させる構造とすることにより、各プレート装着用の孔を別個に設けていた従来の配線器具取付装置(図9参照)に比べ、取付枠10に穿設する孔数が減る。その結果、取付枠10の強度を高く保持することができる。
【0020】
さて、この実施形態では、耐火プレート30を化粧プレート20に係合させて、これら各プレート20,30を一体的に取付枠10へ装着できる構造を採っている。すなわち、化粧プレート20に形成した係合爪22の中央部には、係合溝(係合部)22aが形成してある(図2参照)。そして、耐火プレート30に形成した係合片32の背面(係合部)32aは、この係合溝22aに嵌合する寸法形状に形成してある。
【0021】
図4は化粧プレートに耐火プレートを係合して一体化した状態を示す斜視図、図5は化粧プレートおよび耐火プレートに形成した各係合部の拡大斜視図、図6は同係合部の向きを変えて示す拡大斜視図である。
これらの図に示すように、化粧プレート20の係合爪22に形成した係合溝22aに、耐火プレート30の係合片32を嵌め込むことにより、耐火プレート30と化粧プレート20とを一体化することができる。係合溝22aに嵌め込まれた係合片32の正面は、図5に拡大して示すように、化粧プレート20に形成した係合爪22とほぼ同一の鉤形状となっている。したがって、これら互いに嵌め合わされた化粧プレート20の係合爪22と耐火プレート30の係合片32とは、取付枠10に設けた係合孔14の縁部に、一体的に係合させることができる。
【0022】
上述した構成の配線器具取付装置は、例えば、工場出荷時に化粧プレート20に耐火プレート30を係合させておくことにより、両プレート20,30を一体的な部品として輸送することができ、輸送時の取扱いが容易となる。
配線作業現場では、すでに化粧プレート20に耐火プレート30が係合されているので、これら各プレート20,30を一体的に取付枠10へ装着でき、作業工数が減少する。
【0023】
なお、この発明は上述した一実施形態に限定されるものではない。
例えば、取付枠における装着部を鉤状の突起で形成し、一方、化粧プレートにおける係合手段を該突起と係合する係合孔で形成するとともに、耐火プレートにおける係合手段を該突起と係合する係合溝や係合段部で構成してもよい。
このように構成した場合にも、取付枠における装着部が、各プレート共通の係合部分となるので、構造が簡素化し製作が容易となる。
また、この発明の配線器具取付装置は、化粧プレートと耐火プレートとを別体で輸送することを禁止するものではない。また取付枠に対し、まず耐火プレートを装着し、次いで化粧プレートを装着する作業手順を禁止するものでもない。
【0024】
【発明の効果】
以上説明したように、この発明の配線器具取付装置は、取付枠に化粧プレートおよび耐火プレートを装着するための装着部を形成するとともに、化粧プレートおよび耐火プレートに取付枠の装着部と係合する係合手段をそれぞれ形成したので、取付枠の形状を簡素化しつつ同枠の強度を増強することができる。
また、化粧プレートおよび耐火プレートに形成した各係合手段に、それぞれ相互に係合する係合部を設けたので、作業現場における配線器具の取付け作業工数を減らして、作業性の向上を図ることができ、しかも輸送時の取扱いを容易化することができる。

The present invention relates to a wiring fixture mounting apparatus used for mounting wiring fixtures such as switches and outlets to a wall surface of a building structure, and more particularly to a wiring fixture mounting apparatus provided with a fireproof plate that suppresses the spread of fire.
[0002]
[Prior art]
FIG. 9 is a perspective view showing a conventional wiring fixture mounting apparatus of this type.
The conventional wiring device mounting apparatus shown in FIG. 1 includes a mounting frame 10, a decorative plate 20, and a fireproof plate 30.
[0003]
The mounting frame 10 is a member that is fixed to the wall surface of the building structure and for mounting wiring devices such as switches and outlets. The decorative plate 20 is a member that engages with the mounting frame 10 to cover the surface of the frame 10. And the fireproof plate 30 is provided between the mounting frame 10 and the decorative plate 20, and is a member for suppressing the flame from advancing into the wall space and spreading.
[0004]
Various holes such as a fixing hole 13, a mounting hole 11, and an operation hole 12 are formed in the mounting frame 10 having the above-described functions. Among these, the fixing hole 13 is used when the mounting frame 10 is fixed to the wall surface by screwing.
The mounting hole 11 is drilled in the central portion of the mounting frame 10, and the boss portion of the wiring device is inserted therethrough. Although not shown, a locking portion for locking the wiring device is formed on the back surface side of the peripheral edge of the mounting hole 11. By engaging a locking claw on the wiring device side with this locking portion, the wiring device can be mounted on the mounting frame.
The operation hole 12 is formed around the mounting hole 11. A tool such as a screwdriver is inserted into the operation hole 12, the engagement state between the locking portion and the locking claw on the wiring device side described above is released, and the wiring device can be removed from the mounting frame. ing.
[0005]
Further, the mounting frame 10 is provided with engagement holes 15 and 16 for mounting the decorative plate 20 and the fireproof plate 30 separately. An engaging claw (not shown) formed on the back surface of the decorative plate 20 engages with the engaging hole 15 for the decorative plate, and the decorative plate 20 is mounted on the front surface side of the mounting frame 10. Further, the engaging claw 33 formed on the peripheral edge of the fireproof plate 30 is engaged with the engagement hole 16 for the fireproof plate, and the fireproof plate 30 is mounted on the surface side of the mounting frame 10.
[0006]
In the conventional wiring fixture mounting apparatus having such a configuration, after mounting a required wiring fixture on the mounting frame 10 at a work site, the mounting frame 10 is fixed to the wall surface. Next, after mounting the fireproof plate 30 on the mounting frame 10, the decorative plate 20 is finally mounted on the mounting frame 10 to complete the construction.
[0007]
[Problems to be solved by the invention]
As described above, the conventional wiring device mounting apparatus includes not only the fixing hole 13, the mounting hole 11, and the operation hole 12 in the mounting frame 10, but also the decorative plate engaging hole 15 and the fireproof plate engaging hole 16. Each was drilled separately. When such various holes are drilled, the strength of the mounting frame 10 inevitably decreases. For this reason, conventionally, a reinforcing rib having a complicated shape is formed on the back surface of the mounting frame 10 to ensure a required strength. Therefore, there is a problem that the manufacturing cost is high, such as requiring a mold having a complicated shape, the defect rate is high, and the yield is poor.
[0008]
Further, as is apparent from the above-mentioned procedure of the wiring device mounting work at the work site, the conventional wiring device mounting device has a structure in which the fireproof plate 30 and the decorative plate 20 are separately mounted. Compared to a wiring fixture mounting apparatus that does not include 30, the number of work steps is large. Furthermore, the mounting frame 10, the decorative plate 20, and the fireproof plate 30 must be disassembled and transported, and handling during transportation is complicated.
[0009]
The present invention has been made in view of such circumstances, and an object thereof is to enhance the strength of the frame 10 while simplifying the shape of the mounting frame 10.
Another object of the present invention is to provide a wiring device mounting apparatus that can improve the workability by reducing the number of man-hours for mounting the wiring device at the work site, and can facilitate the handling during transportation.
[0010]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a mounting frame that is fixed to a wall surface, a decorative plate that covers a surface of the mounting frame and that exposes a boss portion of a wiring device, a mounting frame, and a decorative frame. In a wiring fixture mounting apparatus including a fireproof plate interposed between the plate and the mounting frame, a mounting portion for mounting the decorative plate and the fireproof plate is formed on the mounting frame, and the mounting portion is mounted on the decorative plate and the fireproof plate. The engaging means for engaging with the mounting portion of the frame is formed respectively.
[0011]
By setting it as such a structure, a decorative plate and a fireproof plate can be collectively engaged with the mounting part formed in the attachment part. Therefore, for example, even when the mounting portion of the mounting frame is formed in a hole shape that engages with the engaging means, the hole is compared with a structure in which holes (mounting portions) are separately formed on the decorative plate and the fireproof plate. Since the number of drilled portions decreases, the strength increases.
As a result, it is not necessary to form the reinforcing ribs in a complicated manner, and the structure can be simplified and the manufacturing cost can be reduced and the yield can be improved.
[0012]
In the present invention, each engaging means formed on the decorative plate and the fireproof plate may be provided with engaging portions that engage with each other.
If comprised in this way, a decorative plate and a fireproof plate can be mutually engaged and integrated at the time of factory shipment, and handling at the time of transportation becomes easy compared with the case where each component is divided and packed. . Moreover, since the decorative plate and the fireproof plate engaged in advance can be attached to the mounting frame in a lump, the number of mounting work steps can be reduced and the workability can be improved.
[0013]
