【発明の属する技術分野】
本発明は、例えばシステムバスルーム等の浴室の天井に係わり、特に照明装置やスピーカ等の浴室用の付帯器具が配設される浴室天井に関する。
【０００２】
【従来の技術】
従来、ブロー成形、スーパーブロー成形等によって形成される浴室の天井は、例えば図６に示すように形成されている。この浴室天井１００は、外面部１０１と内面部１０２及びこれらの外周を連結する側面部１０３とにより内部に中空部１０４を有する如く成形されると共に、成形と同時に中空部１０４内で発泡材を発泡させることにより発泡層１０５が一体形成され、全体として略同一板厚を有する所定形状（ドーム形状もしくはフラット形状）の板状に形成されている。なお、この種の浴室天井としては、例えば特許文献１に開示されている。
【０００３】

【０００４】
【発明が解決しようとする課題】
しかしながら、このような浴室天井１００においては、全体が略同一板厚の板状に形成されているため、例えば浴室天井１００に照明装置やスピーカ等の浴室用の付帯器具を取り付ける場合に、シール作業を含めた取付作業が面倒であると共に、取付部分に長期に亘り安定したシール状態を確保することが難しいという問題点を有している。
【０００５】
すなわち、浴室用の付帯器具として、例えば、浴槽内にスポットライトを照射し浴室内に反射光による幻想的な雰囲気を醸し出すことが可能なダウンライト照明装置を取り付ける場合、図７に示すように、先ず、浴室天井１００の所定位置の外面部１０１と内面部１０２に所定の大きさの取付孔を形成すると共に、該取付孔部分の発泡層１０５を切除等により取り除いて、上下に貫通した取付孔１０７を形成する。そして、ダウンライト照明装置１０６の本体１０６ａを内面部１０２の取付孔から上方に向けて嵌挿し、取付板１０６ｂを内面部１０２の内面に当接させシール材１０８を介して例えばネジ固定することで、ダウンライト照明装置１０６を浴室天井１００に取り付ける。
【０００６】
この時、浴室天井１００の板厚が天井全域に亘って略同一板厚に設定されていることから、取付孔１０７に取り付けられたダウンライト照明装置１０６は、その本体１０６ａ上部が外面部１０１より上方に所定寸法突出した状態となる。そして、この取付状態において、取付孔１０７により浴室内外が連通状態となることから、浴室内からの水漏れや蒸気漏れを防止するために、取付孔１０７の周囲であるダウンライト照明装置１０６の取付板１０６ｂと内面部１０２との間の全周をシール材１０８で確実にシールする必要がある。そのため、このシール材１０８のシール作業が、特に内面部１０２の表面にしぼ模様がある場合等に困難になったり、シール作業のバラツキ等により安定したシール状態を長期に亘り維持することが難しくなる。
【０００７】
本発明は、このような事情に鑑みてなされたもので、その目的は、天井本体の所定位置に浴室用の付帯器具を簡単に取り付けることができると共に、長期に亘り安定したシール状態を維持することができる浴室天井を提供することにある。
【０００８】
【課題を解決するための手段】
かかる目的を達成すべく、本発明のうち請求項１に記載の発明は、外面部、内面部及び側面部により内部に中空部を有して板状に一体成形された天井本体と、該天井本体の所定位置に配設された浴室用の付帯器具とを有する浴室天井であって、前記天井本体の所定位置に、外面部が外方に膨らみ内面部に取付孔が形成された膨出部を設けると共に、該膨出部の中空部内に内蔵した状態で前記付帯器具を天井本体に取り付けてなることを特徴とする。
【０００９】
このように構成することにより、浴室天井の所定位置に取り付けられる浴室用の付帯器具は、天井本体に予め設けられた膨出部に取り付けられる。この時、付帯器具が膨出部の中空部内に内蔵された状態で取り付けられて天井本体の外面部の外側に露出しないことから、例えば外面部に取付孔等を形成する必要がなくなり、付帯器具を外面部等で確実にシールしつつ簡単に取り付けできる。
【００１０】
そして、前記天井本体は、請求項２に記載の発明のように、その中空部内に発泡材が充填されていることが好ましい。このように構成することにより、中空部に発泡材が充填されることから、浴室天井の剛性等を高めて付帯器具の取付強度アップが図れると共に、発泡材の断熱効果等によって付帯器具から天井各部への熱伝導等が防止される。
【００１１】
また、前記膨出部は、請求項３に記載の発明のように、その外面部に配線用の開口が設けられていることが好ましく、この場合、請求項４に記載の発明のように、前記外面部の開口と付帯器具との間にシール手段が介装されていることが好ましい。このように構成することにより、天井本体の外面部に配線用の開口が設けられていることから、付帯器具を中空部内に内蔵した状態でこの開口から付帯器具の配線を浴室天井外に引き出すことができて、配線構造が簡略化される。この時、比較的小さな開口と付帯器具との間にシール手段を介装することで、付帯器具の取付部分に所定のシール状態が容易に確保される。
【００１２】
また、前記膨出部は、請求項５に記載の発明のように、天井本体に帯状に形成されていることが好ましい。このように構成することにより、膨出部が帯状に形成されていることから、付帯器具の取付位置の自由度が向上し、付帯器具を膨出部の所望位置に簡単に取り付けできる。
【００１３】
【発明の実施の形態】
以下、本発明の実施の形態を図面に基づいて詳細に説明する。
図１〜図４は、本発明に係わる浴室天井の一実施形態を示し、図１が該天井を使用した浴室の内部斜視図、図２が天井の断面図、図３がその平面図、図４が付帯器具の取付方法の説明図である。
【００１４】
図１において、システムバスルーム等の浴室１は、防水パン２と、４枚の浴室壁面としての壁パネル３ａ〜３ｄ（壁パネル３ｄは図示せず）及び浴室天井の天井本体としての例えばドーム型の２枚の天井パネル４ａ、４ｂによって略箱状に形成され、前記防水パン２の壁パネル３ａ側には浴槽５が設置されると共に、この浴槽５の側方の防水パン２上には洗い場６が設けられている。また、洗い場６の壁パネル３ｂ側にはカウンタ７が設けられ、このカウンタ７上方の壁パネル３ｂには、水栓９、シャワー１０、ミラー１１、収納棚１２等が一体的に組み込まれたミラーパネル８が配置されている。
【００１５】
また、前記天井パネル４ａには、浴槽５内にスポットライトを照射し、水面からの反射光により浴室１内に光による幻想的な雰囲気を醸し出すための付帯器具としてのダウンライト照明装置１３（以下、単に照明装置１３という）が配置されている。この照明装置１３は、例えばブロー成形等によって一体成形された浴槽５側の天井パネル４ａの膨出部１４に取り付けられている。すなわち、天井本体としての前記天井パネル４ａ、４ｂは、図２及び図３に示すように、外面部１５と内面部１６及び側面部１７とで内部に中空部１８を有して一体成形される共に、中空部１８内に成形と同時に発泡ウレタン等の発泡材１９が充填され、全体としてドーム形状を呈した所定板厚の板状に形成されている。
【００１６】
そして、２枚の天井パネル４ａ、４ｂのうち浴槽５側の天井パネル４ａには、ドーム形状の曲線方向イの略中間位置に、外面部１５が外方に所定寸法膨出した膨出部１４が一体形成されている。この膨出部１４は、例えば幅Ｗ・厚さＴで天井パネル４ａの曲線方向イの略中間位置に平面視で略正方形状（もしくは円形等）に形成されている。また、膨出部１４には、その内面部１６に形成された所定内径の取付孔２０ａと、内面部１６上の発泡材１９に形成され取付孔２０ａと略同一大きさの取付孔２０ｂからなる取付孔２０が形成され、この取付孔２０の上部の外面部１５には、取付孔２０より小径の開口２１が形成されている。
【００１７】
一方、前記照明装置１３は、内部にハロゲンランプ等の照明灯２３ａが内蔵された有底筒状の本体２３と、この本体２３の光の照射口となる開口端部に鍔状に形成された取付部２４と、本体２３の底部２３ｂから外部に引き出された配線２５（電源コード）等で構成されている。そして、この照明装置１３は、その本体２３が膨出部１４の取付孔２０内に内蔵された状態で、取付部２４が内面部１６の内面にネジ２７で固定されることで膨出部１４に取り付けられ、この時、照明装置１３の本体２３の底部２３ｂと膨出部１４の外面部１５の内面間にはシール材２６（シール手段）が介装されている。
【００１８】
なお、この例では、天井パネル４ａに一体形成される膨出部１４を、照明装置１３の取付位置に該照明装置１３の形状に略対応する大きさで設けたが、例えば図３の二点鎖線ａで示すように、天井パネル４ａの曲線方向イと直交する方向に該天井パネル４ａの幅と略同一長さで帯状に設けることもできるし、二点鎖線ｂで示すように、天井パネル４ａの曲線方向イと平行に所定長さの帯状に設けることもできる。このように膨出部１４を帯状に設けた場合は、照明装置１３の取付位置の自由度を向上させることができる。また、平面視所定形状もしくは帯状の膨出部１４の位置も、例えば二点鎖線ｃに示すように天井パネル４ａの中央位置からずらした位置に設けることもできるし、膨出部１４自体の高さＴや幅Ｗ等の形状も付帯器具（照明装置１３）の形状等に応じて適宜に変更できる。
【００１９】
ここで、この照明装置１３の天井パネル４ａへの取付方法の一例を、図４に基づいて説明する。先ず、天井パネル４ａ、４ｂはそれぞれ所定の型によって成形され、浴槽側の天井パネル４ａには設計段階で予め設定された位置に膨出部１４が一体形成される。この膨出部１４は、成形時において図４（ａ）に示すように、膨出部１４の外面部１５と内面部１６及び発泡材１９は取付孔２０や開口２１の無い状態で形成されている。
【００２０】
そして、この状態で、平面視略正方形状の膨出部１４の内面部１６に、例えば所定内径の円形の取付孔２０ａを穿設し、この取付孔２０ａに対応させてその上部の発泡材１９を切除等によって取り除いて取付孔２０ｂを形成する。これにより、図４（ｂ）に示すように、膨出部１４の内面部１６と発泡材１９に照明装置１３の本体２３の外径に対応した取付孔２０が形成される。また、取付孔２０の略中心位置の外面部１５に比較的小さい所定内径の例えば円形の開口２１を穿設する。
【００２１】
膨出部１４に取付孔２０と開口２１を形成したら、取付孔２０の内面部１６側から、照明装置１３の本体２３を図４（ｂ）の矢印ロの如く嵌挿させると共に、開口２１から本体２３の配線２５を外面部１５の外方に引き出し、本体２３を膨出部１４の取付孔２０内に位置させる。この時、本体２３の底部２３ｂに円環状で所定板厚（あるいは適宜形状）のシール材２６を貼付等により固着すると共に、シール材２６の孔から配線２５を上方に引き出した状態で本体２３を取付孔２０内に嵌挿し、照明装置１３の取付部２４を膨出部１４の内面部１６内面に当接させる。
【００２２】
この状態で、取付部２４を内面部１６にネジ２７で固定することにより、照明装置１３が天井パネル４ａの膨出部１４に取り付けられ、この時、照明装置１３の本体２３は、膨出部１４の内部に内蔵されると共に、本体２３の底部２３ｂと膨出部１４の外面部１５内面との間にシール材２６が介装された状態となる。このシール材２６により、外面部１５に形成された開口２１部分がシールされ、取付孔２０部分における天井パネル４ａの内外の気密性が確保されて、図２に示すように、照明装置１３が膨出部１４に取り付けられる。なお、本体２３の高さ寸法と膨出部１４の高さ寸法Ｔ等により、本体２３の底部２３ｂに固着されたシール材２６の板厚が予め所定値に設定されることで、シール材２６が本体２３と外面部１５の内面間にシール状態で介装されることになる。
【００２３】
このように、上記実施形態の浴室１の天井パネル４ａにあっては、天井パネル４ａの所定位置に外面部１５が外方に膨出した膨出部１４が一体形成され この膨出部１４の内部に照明装置１３の本体２３が内蔵した状態で取り付けられるため、本体２３を外面部１５の外方に突出させることなく、照明装置１３を天井パネル４ａに見栄え良く取り付けることができると共に、照明装置１３の配線２５が外面部１５に形成された小さな開口２１から天井パネル４ａの外側に引き出されるため、配線作業を簡単かつ見栄え良くに行うことができる。また、照明装置１３が取り付けられる膨出部１４の取付孔２０のシールが、開口２１部分に例えば円環状のシール材２６を介装させることで行われるため、シール作業自体を簡単に行うことができる。
【００２４】
特に、照明装置１３の取付部２４を内面部１６の表面に浴室１内側からネジ２７で固定するだけで、該固定位置とは別位置の本体２３の底部２３ｂ側でシールされることから、従来のような取付部２４における面倒なシール作業が不要となると共に、内面部１６表面のしぼ模様の有無等に係わらず、確実なシール状態を容易に確保することができる。また、膨出部１４が天井パネル４ａの成形時に同時に形成されるため、照明装置１３の取付位置をこの膨出部１４によって的確かつ容易に把握することができ、照明装置１３の取付作業が一層容易に行え、これらのことから、照明装置１３のシール作業や配線作業を含め、その取付作業を簡単かつ効率的に行うことが可能になる。
【００２５】
また、膨出部１４の照明装置１３取付用の取付孔２０が配線用の小さな開口２１を介して内外に連通するのみであるため、開口２１部分をシール材２６でシールするだけで取付孔２０の内外を確実にシールすることができ、シール作業の容易化による作業バラツキの抑制と併せ、一層確実なシール構造が得られて、照明装置１３を長期に亘り安定したシール状態で天井パネル４ａに取り付けることが可能になる。
【００２６】
また、照明装置１３の本体２３が膨出部１４の取付孔２０内に内蔵状態で取り付けられると共に、本体２３が発泡材１９と外面部１５等で取り囲まれた状態となるため、本体２３の振動や熱等の各部への伝達を発泡材１９等で防止できて、特にモータを有する付帯器具等にも好適に使用することが可能になる。
【００２７】
また、天井パネル４ａに予め取付孔２０や開口２１の無い状態で膨出部１４が一体形成されているため、照明装置１３等の付帯器具を取り付けないレイアウトの場合には、通常の天井パネルとして使用することもでき、各種レイアウトの浴室天井に適用可能な汎用性の高い天井パネル４ａを得ることが可能になる。また、膨出部１４を予め帯状に形成することにより、照明装置１３の取付位置を膨出部１４上の適宜位置に設定できて、照明装置１３等の取付位置の自由度を向上させることも可能になる。
【００２８】
なお、以上の例においては、付帯器具が照明装置１３でその本体２３に配線２５が設けられている場合について説明したが、例えば配線２５が不要な装飾用ライト等のような付帯器具の場合は、図５に示すようにして天井パネル４ａの膨出部１４に取り付けられる。すなわち、膨出部１４の内面部１６と発泡材１９に取付孔２０を形成し、この取付孔２０内に付帯器具２９の本体３０を内蔵した状態でその取付部３１を内面部１６に例えばネジ２７（もしくは接着）固定する。この時、外面部１５には配線用の開口２１を設ける必要はなく、取付孔２０部分における内外の気密性が開口２１の無い外面部１５で確実に確保されつつ、膨出部１４の内部空間が付帯器具２９の取付スペースとして使用されることになる。
【００２９】
また、上記実施形態においては、天井パネル４ａに取り付けられる付帯器具がダウンライト用の照明装置１３である場合について説明したが、本発明はこれに限定されず、例えば他の適宜の照明装置、浴室換気扇あるいは浴室音響装置のスピーカ等にも適用することができる。この時、特にスピーカの場合は、例えば膨出部１４を帯状に形成することで、この帯状の膨出部１４の両端部に左右のスピーカをそれぞれ取り付けることができると共に、帯状の膨出部１４によって例えば天井パネル４ａ自体の剛性アップを図ることも可能になる。
【００３０】
さらに、上記実施形態においては、天井パネル４ａがドーム型である場合について説明したが、例えば図５に示すように、フラット型の天井パネル４ａにも適用できるし、上記実施形態における浴室１内部の形状や天井パネル４ａ、４ｂ自体の構造等も一例であって、例えば天井パネル４ａ、４ｂとして内部に発泡材１９が充填されない中空部１８を有する構造のものを使用する等、本発明に係わる各発明の要旨を逸脱しない範囲において適宜に変更することができる。
【００３１】
【発明の効果】
以上詳述したように、請求項１に記載の発明によれば、付帯器具を天井本体の所定位置に予め設けられた膨出部の中空部内に内蔵した状態でかつ天井本体の外面部の外側に露出しない状態で取り付けできるため、例えば外面部に取付孔等を形成する必要がなくなり付帯器具の取付作業が簡単に行えると共に、外面部等により付帯器具を長期に亘り安定したシール状態で浴室天井に配設することができる。
【００３２】
また、請求項２に記載の発明によれば、請求項１に記載の発明の効果に加え、天井本体の中空部内に発泡材が充填されているため、発泡材で浴室天井の剛性等を高めて付帯器具の取付強度をアップすることができると共に、発泡材の断熱効果等によって付帯器具から天井各部への熱伝導等を防止することができて、付帯器具の一層安定した取付状態を得ることができる。
【００３３】
また、請求項３に記載の発明によれば、請求項１または２に記載の発明の効果に加え、天井本体の外面部に配線用の開口が設けられているため、開口から付帯器具の配線を浴室天井外に簡単に引き出すことができて、配線構造等を簡略化することができる。
【００３４】
また、請求項４に記載の発明によれば、請求項３に記載の発明の効果に加え、外面部の開口と付帯器具との間にシール手段が介装されているため、シール手段により配線用の比較的小さめの開口部分を確実にシールでき、シール作業自体を簡単かつ確実に行うことができる。
【００３５】
また、請求項５に記載の発明によれば、請求項１ないし４に記載の発明の効果に加え、膨出部が帯状に形成されているため、付帯器具の取付位置が特定されず膨出部の所望位置に取り付けできて、付帯器具の設置の自由度の向上が図れる等の効果を奏する。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a ceiling of a bathroom such as a system bathroom, and more particularly to a bathroom ceiling in which auxiliary equipment for a bathroom such as a lighting device and a speaker is provided.
[0002]
[Prior art]
Conventionally, the ceiling of a bathroom formed by blow molding, super blow molding or the like is formed as shown in FIG. 6, for example. The bathroom ceiling 100 is formed so as to have a hollow portion 104 inside by an outer surface portion 101, an inner surface portion 102, and a side surface portion 103 connecting the outer periphery thereof, and a foam material is foamed in the hollow portion 104 at the same time as the molding. By doing so, the foam layer 105 is integrally formed, and is formed in a plate shape of a predetermined shape (dome shape or flat shape) having substantially the same plate thickness as a whole. Note that this type of bathroom ceiling is disclosed, for example, in Patent Document 1.
[0003]
[Patent Document 1]
JP-A-9-203155
[Problems to be solved by the invention]
However, since such a bathroom ceiling 100 is entirely formed in a plate shape having substantially the same thickness, for example, when attaching a bathroom accessory such as a lighting device or a speaker to the bathroom ceiling 100, a sealing operation is performed. Is troublesome, and it is difficult to secure a stable sealing state for a long time in the mounting portion.
[0005]
That is, as an accessory for the bathroom, for example, when attaching a downlight lighting device capable of irradiating a spotlight in the bathtub and creating a fantastic atmosphere by reflected light in the bathroom, as shown in FIG. First, a mounting hole of a predetermined size is formed in the outer surface portion 101 and the inner surface portion 102 at a predetermined position of the bathroom ceiling 100, and the foam layer 105 in the mounting hole portion is removed by cutting or the like, and the mounting hole penetrated vertically. 107 is formed. Then, the main body 106a of the downlight illuminating device 106 is inserted upward from the mounting hole of the inner surface portion 102, the mounting plate 106b is brought into contact with the inner surface of the inner surface portion 102, and for example, is fixed with a screw via a seal member 108. Then, the downlight illumination device 106 is attached to the bathroom ceiling 100.
[0006]
At this time, since the plate thickness of the bathroom ceiling 100 is set to be substantially the same throughout the entire ceiling, the downlight illumination device 106 attached to the attachment hole 107 has its main body 106 a upper part higher than the outer surface part 101. It is in a state of projecting upward by a predetermined dimension. In this mounting state, since the inside and outside of the bathroom are in communication with each other by the mounting hole 107, the downlight illumination device 106 around the mounting hole 107 is mounted to prevent water leakage and steam leakage from the bathroom. It is necessary to securely seal the entire periphery between the plate 106b and the inner surface portion 102 with the sealing material 108. Therefore, the sealing work of the sealing material 108 becomes difficult particularly when there is a grain pattern on the surface of the inner surface portion 102, and it becomes difficult to maintain a stable sealing state for a long time due to variations in the sealing work. .
[0007]
The present invention has been made in view of such circumstances, and an object of the present invention is to easily attach an accessory for a bathroom to a predetermined position of a ceiling main body and to maintain a stable sealing state for a long time. It is in providing a bathroom ceiling that can be.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, an invention according to claim 1 of the present invention provides a ceiling body integrally formed in a plate shape having a hollow portion inside by an outer surface portion, an inner surface portion, and a side surface portion; A bathroom ceiling having a bathroom accessory provided at a predetermined position of a main body, a bulging portion having an outer surface bulging outward at a predetermined position of the ceiling main body and a mounting hole formed at an inner surface portion. And the accessory is attached to the ceiling main body in a state of being built in the hollow portion of the bulging portion.
[0009]
With this configuration, the bathroom accessory attached to a predetermined position on the bathroom ceiling is attached to a bulging portion provided in advance on the ceiling main body. At this time, since the accessory is mounted inside the hollow portion of the bulging portion and is not exposed to the outside of the outer surface of the ceiling body, it is not necessary to form a mounting hole or the like in the outer surface, for example. Can be easily attached while being securely sealed with an outer surface or the like.
[0010]
And it is preferable that the foaming material is filled in the hollow part of the ceiling main body as in the second aspect of the present invention. With this configuration, since the hollow portion is filled with the foam material, the rigidity and the like of the bathroom ceiling can be increased to increase the attachment strength of the accessory, and the heat insulating effect of the foam material and the like to separate the ceiling components from the accessory device. And the like is prevented from conducting heat.
[0011]
Further, the bulging portion is preferably provided with an opening for wiring on the outer surface thereof as in the invention according to claim 3, and in this case, as in the invention according to claim 4, Preferably, a sealing means is interposed between the opening on the outer surface and the accessory. With this configuration, since the wiring opening is provided on the outer surface of the ceiling main body, the wiring of the accessory is drawn out of the bathroom ceiling from this opening with the accessory installed inside the hollow portion. And the wiring structure is simplified. At this time, by providing the sealing means between the relatively small opening and the accessory, a predetermined sealing state can be easily secured at the attachment portion of the accessory.
[0012]
Further, it is preferable that the bulging portion is formed in a strip shape on the ceiling main body as in the invention according to claim 5. With this configuration, since the bulging portion is formed in a belt shape, the degree of freedom of the attachment position of the accessory is improved, and the accessory can be easily attached to a desired position of the bulging portion.
[0013]
BEST MODE FOR CARRYING OUT THE INVENTION

It is composed of a mounting portion 24 and a wiring 25 (power supply cord) drawn out from the bottom portion 23b of the main body 23 to the outside. The illuminating device 13 is configured such that the mounting portion 24 is fixed to the inner surface of the inner surface portion 16 with the screw 27 in a state where the main body 23 is incorporated in the mounting hole 20 of the bulging portion 14. At this time, a sealing material 26 (sealing means) is interposed between the bottom 23 b of the main body 23 of the lighting device 13 and the inner surface of the outer surface 15 of the bulging portion 14.
[0018]
In this example, the bulging portion 14 integrally formed on the ceiling panel 4a is provided at a mounting position of the lighting device 13 with a size substantially corresponding to the shape of the lighting device 13. However, for example, two points in FIG. As shown by the chain line a, the ceiling panel 4a can be provided in a strip shape in the direction orthogonal to the curved direction a of the ceiling panel 4a and substantially the same length as the width of the ceiling panel 4a, or as shown by the two-dot chain line b It may be provided in a belt shape of a predetermined length in parallel with the curved direction a of 4a. When the swollen portion 14 is provided in a strip shape in this manner, the degree of freedom of the mounting position of the lighting device 13 can be improved. Also, the position of the bulging portion 14 having a predetermined shape or a band shape in plan view can be provided at a position shifted from the center position of the ceiling panel 4a as shown by a two-dot chain line c, for example. The shape such as the height T and the width W can be appropriately changed according to the shape of the accessory (illumination device 13).
[0019]
Here, an example of a method of attaching the lighting device 13 to the ceiling panel 4a will be described with reference to FIG. First, each of the ceiling panels 4a and 4b is formed by a predetermined mold, and the bulging portion 14 is integrally formed on the ceiling panel 4a on the bathtub side at a position set in advance in the design stage. As shown in FIG. 4A, the swelling portion 14 is formed such that the outer surface portion 15 and the inner surface portion 16 of the swelling portion 14 and the foam material 19 do not have the mounting hole 20 and the opening 21 at the time of molding. I have.
[0020]
Then, in this state, a circular mounting hole 20a having a predetermined inner diameter, for example, is formed in the inner surface 16 of the bulging portion 14 having a substantially square shape in a plan view. Is removed by cutting or the like to form a mounting hole 20b. Thereby, as shown in FIG. 4B, a mounting hole 20 corresponding to the outer diameter of the main body 23 of the lighting device 13 is formed in the inner surface 16 of the bulging portion 14 and the foam material 19. In addition, a relatively small, for example, circular opening 21 having a predetermined inner diameter is formed in the outer surface portion 15 substantially at the center of the mounting hole 20.
[0021]
After the mounting hole 20 and the opening 21 are formed in the bulging portion 14, the main body 23 of the lighting device 13 is inserted from the inner surface 16 side of the mounting hole 20 as shown by the arrow B in FIG. The wiring 25 of the main body 23 is pulled out of the outer surface portion 15, and the main body 23 is positioned in the mounting hole 20 of the bulging portion 14. At this time, an annular seal member 26 having a predetermined thickness (or an appropriate shape) is fixed to the bottom portion 23b of the main body 23 by attaching or the like, and the main body 23 is pulled out with the wiring 25 pulled out from the hole of the seal material 26 upward. The fitting portion 24 of the lighting device 13 is fitted into the fitting hole 20 so that the fitting portion 24 of the lighting device 13 contacts the inner surface 16 of the bulging portion 14.
[0022]
In this state, by fixing the mounting portion 24 to the inner surface portion 16 with the screw 27, the lighting device 13 is mounted on the bulging portion 14 of the ceiling panel 4a. At this time, the main body 23 of the lighting device 13 is 14, and a sealing material 26 is interposed between the bottom 23 b of the main body 23 and the inner surface of the outer surface 15 of the bulging portion 14. The sealing member 26 seals the opening 21 formed in the outer surface portion 15 and secures the airtightness between the inside and the outside of the ceiling panel 4a at the mounting hole 20 portion, and as shown in FIG. It is attached to the outlet 14. The thickness of the sealing material 26 fixed to the bottom 23b of the main body 23 is set in advance to a predetermined value based on the height dimension of the main body 23 and the height dimension T of the bulging portion 14, and the like. Is interposed between the main body 23 and the inner surface of the outer surface portion 15 in a sealed state.
[0023]
As described above, in the ceiling panel 4a of the bathroom 1 of the above embodiment, the bulging portion 14 in which the outer surface portion 15 bulges outward is formed integrally at a predetermined position of the ceiling panel 4a. Since the main body 23 of the lighting device 13 is mounted inside the main body 23, the lighting device 13 can be mounted on the ceiling panel 4 a with good appearance without projecting the main body 23 to the outside of the outer surface portion 15. Since the thirteen wirings 25 are drawn out of the ceiling panel 4a from the small openings 21 formed in the outer surface part 15, the wiring work can be performed easily and with good appearance. In addition, since the sealing of the mounting hole 20 of the bulging portion 14 to which the lighting device 13 is mounted is performed by interposing the annular sealing material 26 in the opening 21, for example, the sealing operation itself can be easily performed. it can.
[0024]
In particular, since the mounting portion 24 of the lighting device 13 is simply fixed to the surface of the inner surface portion 16 with the screw 27 from the inside of the bathroom 1, it is sealed on the bottom portion 23 b side of the main body 23 at a position different from the fixing position. This eliminates the need for troublesome sealing work at the mounting portion 24, and can easily ensure a reliable sealing state regardless of the presence or absence of a grain pattern on the surface of the inner surface portion 16. Further, since the bulging portion 14 is formed at the same time as the ceiling panel 4a is formed, the mounting position of the lighting device 13 can be accurately and easily grasped by the bulging portion 14, and the mounting work of the lighting device 13 is further improved. It can be easily performed, and from these, it is possible to easily and efficiently perform the mounting work including the sealing work and the wiring work of the lighting device 13.
[0025]
Also, since the mounting hole 20 for mounting the lighting device 13 of the bulging portion 14 only communicates inside and outside via the small opening 21 for wiring, the opening 21 portion is merely sealed with the seal material 26 and the mounting hole 20 is formed. Inside and outside of the ceiling panel 4a can be reliably sealed, and in addition to suppressing the work variation by facilitating the sealing operation, a more reliable sealing structure can be obtained, and the lighting device 13 can be stably sealed over a long period of time on the ceiling panel 4a. It becomes possible to attach.
[0026]
In addition, the main body 23 of the lighting device 13 is mounted in the mounting hole 20 of the bulging portion 14 in a built-in state, and the main body 23 is surrounded by the foam material 19 and the outer surface portion 15. The transmission of heat, heat and the like to each part can be prevented by the foam material 19 or the like, so that it can be suitably used especially for an accessory having a motor or the like.
[0027]
In addition, since the bulging portion 14 is integrally formed in the ceiling panel 4a without the mounting hole 20 and the opening 21 in advance, in the case of a layout in which auxiliary equipment such as the lighting device 13 is not mounted, a normal ceiling panel is used. It is possible to obtain a highly versatile ceiling panel 4a that can be used and can be applied to bathroom ceilings of various layouts. In addition, by forming the bulging portion 14 in a band shape in advance, the mounting position of the lighting device 13 can be set to an appropriate position on the bulging portion 14, and the degree of freedom of the mounting position of the lighting device 13 and the like can be improved. Will be possible.
[0028]
In the above example, the case has been described where the accessory is the lighting device 13 and the wiring 25 is provided on the main body 23. However, in the case of an accessory such as a decorative light that does not require the wiring 25, for example, 5 is attached to the bulging portion 14 of the ceiling panel 4a as shown in FIG. That is, a mounting hole 20 is formed in the inner surface portion 16 of the bulging portion 14 and the foam material 19, and the mounting portion 31 is attached to the inner surface portion 16 with the main body 30 of the accessory 29 built in the mounting hole 20. 27 (or adhere). At this time, it is not necessary to provide an opening 21 for wiring in the outer surface portion 15, and the inner and outer airtightness in the mounting hole 20 portion is reliably secured by the outer surface portion 15 having no opening 21, and the internal space of the bulging portion 14 is secured. Is used as a mounting space for the accessory 29.
[0029]
In the above embodiment, the case where the accessory attached to the ceiling panel 4a is the lighting device 13 for downlight has been described, but the present invention is not limited to this, and for example, other appropriate lighting devices, bathrooms, and the like. The present invention can also be applied to a ventilation fan, a speaker of a bathroom acoustic device, and the like. At this time, in the case of a speaker in particular, for example, by forming the bulging portion 14 in a band shape, the left and right speakers can be attached to both ends of the band-shaped bulging portion 14, respectively. This makes it possible to increase the rigidity of the ceiling panel 4a itself, for example.
[0030]
Further, in the above embodiment, the case where the ceiling panel 4a is dome-shaped has been described. However, for example, as shown in FIG. 5, the ceiling panel 4a can be applied to a flat ceiling panel 4a. The shape and the structure of the ceiling panels 4a and 4b themselves are also examples. For example, each of the ceiling panels 4a and 4b having a structure having a hollow portion 18 in which the foam material 19 is not filled is used as the ceiling panels 4a and 4b. Changes can be made as appropriate without departing from the spirit of the invention.
[0031]
