Description

【０００１】
【発明の属する技術分野】
本発明は、浴室ユニットやシャワー室ユニットのような、室内床面に水を流す、洗い場付き浴槽を含む防水床パンを有する衛生設備室ユニットに関するものである。
【０００２】
【従来の技術】
従来、浴室ユニットやシャワー室ユニットのような、室内床面に水を流す衛生設備室ユニットを構成する場合、一般的には、防水床パンの周囲に床面より一段高く設けた壁載せ部に、壁パネル及び出入口枠を組み立て、その上に天井パネルを載置している。
ところが、近年の高齢者や障害者に対する配慮、いわゆるバリアフリー仕様の要求の高まりに伴って、出入口部の段差を小さく抑える必要から、少なくとも出入口枠を取り付ける部分の壁載せ部、言い替えれば出入口枠載せ部は、床面と略同一高さ、更には床面より一段低い高さに形成するようになってきている。
【０００３】
一方、衛生設備室ユニットの出入口枠の取付位置は、他の部屋との位置関係から、いくつかの所定の位置から任意の位置を選択できるようにする必要がある。
しかるに、出入口枠を取り付ける部分の壁載せ部と他の壁パネルを取り付ける部分の壁載せ部の高さを変えてしまうと、所定の出入口枠取付位置ごとに異なる防水床パンが必要になる。即ち、防水床パンの種類が増加し、それを生産する生産型も多くなるので、コストの高騰と、生産及び物流上の課題の増加を招くばかりか、施工現場での融通性が失われてしまう。つまり、設計変更による出入口枠取付位置の変更や防水床パンの選択ミスなどが発生した場合には、防水床パンを再度取り寄せる必要があり、工事の遅延とコストの高騰を招くことになる。
【０００４】
このため、壁パネルを取り付ける部分の壁載せ部をも、出入口枠を取り付ける部分の壁載せ部の高さに合わせて、床面と略同一高さ、更には床面より一段低い高さに形成するようになってきているが、例えば、特許第２７５１７８４号「ユニットバスルーム」のように、壁載せ部は水平面で、その外側に防水リムなどと呼ばれる立上り片を有し、この水平面上に壁パネルと出入口枠を載置するものや、特開平１０−８８６３７「防水パン」に見られるように、出入口枠は壁載せ部に直接載置し、壁パネルは壁載せピース、補助部材などと呼ばれる壁載せ材を介して載置されるなど、様々な形状や形式が派生してきている。
【０００５】
ところで、更に高度なバリアフリー仕様では、防水床パンの出入口枠に接する床面外縁と隣室の床面とが略同一の高さで、かつ、出入口枠の下枠上端面が、これらの床面より著しく高くないこと、具体的には、防水床パンの出入口枠に接する床面外縁と隣室の床面との内の低い方と、出入口枠の下枠上端面との高さの差が３ミリメートル以下であることが要求される。従って、衛生設備室ユニットでは、防水床パンの出入口枠に接する床面外縁と出入口枠の下枠上端面との高さの差を、最大３ミリメートルに抑える必要がある。この要求を満足し、かつ、いくつかの所定の出入口枠取付位置から任意の位置を選択できるようにするためには、防水床パンの、少なくとも出入口枠を設けることができる部分の床面外縁を、全長に渉って略同一高さに形成する必要がある。
【０００６】
なお、出入口の扉先端部は、扉の自重や使用時の荷重、丁番の摩耗などにより垂下し易いものであることを考慮すると、床面との干渉を防止するため、少なくとも内開き扉の場合は、一般的に、扉の可動範囲内にある防水床パンの床面を、出入口枠に接する床面外縁よりも高くすることはできない。従って、床面の排水性を考慮すると、床面外縁から内側に向けた排水勾配を設けることになる。
又、床面外縁と出入口枠の下枠上端面との差を３ミリメートル以下に抑えるためには、下枠の高さを考慮すると、一般的には、下枠の少なくとも一部は床面外縁より低くする必要がある。即ち、壁載せ部は床面外縁より一段低く形成する必要がある。ただし、下枠の高さを３ミリメートル以下にしたり、下枠そのものを省略することも不可能ではないので、これは絶対必要条件ではない。
【０００７】
以上を総合すると、いくつかの所定の出入口枠取付位置から任意の位置を選択できる、高度なバリアフリー仕様の衛生設備室ユニット用の防水床パンは、少なくとも出入口枠を設けることができる床面外縁全てを、略同じ高さに形成するとともに、この面より低い位置に設けた床排水口に向けて排水勾配を設けることが要求される。更に、一般的には、少なくとも出入口枠を設けることができる床面外縁の外側に設ける壁載せ部を、この面よりも一段低く形成することも要求される。
なお、ここにいう床面外縁には、床面の外周部に設けた排水溝の溝蓋の上面外縁をも含んでいる。
【０００８】
上記の条件を満足する衛生設備室ユニット用の防水床パンは、既に多く存在する。しかし、床面の排水勾配は、一般的には４０分の１から１００分の１程度で、しかも、扉を開き切った際に扉先端部が位置する部分は、通常は、床面外縁に近い部分になるため、この部分の床面高さは、床面外縁上面からいくらも低くならない。一方、扉先端部は、正常な場合でも上記の通り自重や使用時の荷重、丁番の摩耗などによって下がり気味になる傾向があるし、出入口枠の縦枠の傾きなどにより、扉を取り付ける上下の丁番の総合軸心が、鉛直線よりわずかでも傾くと、その傾きの方向によっては、扉を開いた際に、扉先端部が下がってくることになる。
従って、扉を閉めた状態では、出入口枠内に正常に納まり、扉と出入口枠が擦ることがなくても、扉を開くと、新設時から扉先端部が床面と擦る、又は、新設時は問題なくても、時間の経過とともに扉先端部が次第に垂下して、床面と擦るようになるなどの、解決すべき課題がある。
このような課題を解決するものとして、扉を開くと扉がせり上がる、せり上がり丁番とかグレビティヒンジとか呼ばれる丁番もあるが、せり上がり機構のために、扉の開閉動作、とりわけ開扉動作がスムーズでないばかりか、コストの高騰を招くという、別の課題が生じている。
【０００９】
【発明が解決しようとする課題】
本発明は、上記課題を解決するためになされたもので、本発明の目的は、同一の防水床パンを使用しながら、いくつかの所定の出入口枠取付位置から任意の位置を選択でき、かつ、出入口部段差に関する高度なバリアフリー仕様、即ち出入口枠に接する床面外縁と出入口枠の下枠上端面との差が３ミリメートル以下である仕様を実現でき、なおかつ、新設時は勿論、時間が経過して扉先端部が多少垂下しても、扉と床面とが擦ることのない、扉の開閉がスムーズでしかも安価な衛生設備室ユニットを提供することにある。
【００１０】
【課題を解決するための手段】
本発明の各請求項記載の衛生設備ユニットについて、上記課題を解決するために施した手段を説明する。
【００１１】
本発明の請求項１記載の衛生設備室ユニットでは、同一の防水床パンを使用しながら、いくつかの所定の出入口枠取付位置から任意の位置を選択でき、かつ、出入口段差に関するバリアフリー仕様を実現するために、少なくとも上記出入口枠を設けることができる部分の床面外縁を、全長に渉って略同一高さに形成された防水床パンを採用した。
更に、出入口部段差に関する高度なバリアフリー仕様を実現し、かつ、新設時は勿論、時間が経過して扉先端部が多少垂下しても、扉と床面とが擦ることのない、扉の開閉がスムーズでしかも安価な衛生設備室ユニットとするために、出入口枠の下枠と前記床面外縁との段差を微小にし、且つ床面外縁から内側の幅数センチメートル乃至十数センチメートルの範囲を、当該範囲に連続的に接続する他の傾斜した床面よりも急勾配の内向き斜面とし、扉を開き切った場合の扉先端部が位置する部分の床面外縁が前記出入口枠を設けることができる部分である場合、開き切った扉の先端部よりも床面外縁寄りに、前記範囲の内縁を位置決めした。
【００１２】
本発明の請求項２記載の衛生設備ユニットでは、請求項１記載の衛生設備ユニットでは不十分な場合、即ち、扉を開き切った際に扉先端部が位置する部分が出入口枠を設けることができる部分でない場合にも、扉先端部が床面と擦らないようにするために、この部分の床面外縁の高さ及びその内側の形状を、出入口枠を設けることができる部分の床面外縁の高さ及びその内側の形状と、略同一高さ、略同一形状とした。
【００１３】
【発明の実施の形態】
以下、本発明の実施の形態を、実施形態の図面を参照しつつ説明する。
【００１４】
図１は、本発明の第１実施形態の、衛生設備室ユニットの平面図、図２は、第１実施形態の、Ａ−Ａ要部断面図、図３は、第１実施形態の、Ｂ−Ｂ要部断面図である。
【００１５】
衛生設備室ユニット１は、防水床パン２の壁載せ部２４の上に、壁パネル４、出入口枠３を載置し、その上に天井パネル（図示せず）を載せて躯体が構成され、その中に浴槽６などの器具類を載置又は取り付けて完成される。防水床パン２と壁パネル４及び出入口枠３とは、水密手段７、即ち本実施形態ではコーキング７１によって、水密的に接合されており、壁パネル４相互及び壁パネル４と出入口枠３も、適当な水密的接合手段（図示せず）で接合されている。
【００１６】
本実施形態の衛生設備室ユニット１では、出入口枠３の取付位置を、図１に示した位置以外に、図１の△印Ｐ、Ｑ、Ｒの各部分を中心とする取付位置からも任意に選択することができるように、浴槽６側を除く洗い場２５の全周の床面外縁２１を、全長に渉って略同一高さに形成するとともに、この床面外縁２１から内側の幅数センチメートル乃至十数センチメートルの範囲を、他の床面部分即ち一般勾配部分２２よりも急勾配の内向き斜面即ち急斜面２３としている。
なお、壁載せ部２４は、防水床パン２の床面外縁２１より一段低く、かつ全周に形成されている。又、出入口枠３には、扉３３が取り付けられ、扉３３と下枠３１との間は扉水密手段３６、本実施例では水密パッキン３６１によって、水密性が略保たれている。
なお、３２は下枠上端面で、本実施形態では、高度なバリアフリー仕様を満足するために、床面外縁２１より３ミリメートル以下の高さに抑えられている。
【００１７】
本実施形態では、上記のように構成したので、同一の防水床パンを使用しながら、いくつかの所定の出入口枠取付位置から任意の位置を選択でき、かつ、出入口部段差に関する高度なバリアフリー仕様を実現できる。このことは、扉３３開閉時の床面との擦り問題を除けば、上記構成から明白である。
又、上記の構成により、新設時は勿論、時間が経過して扉先端部が多少垂下しても、扉３３と床面とが擦ることのない、扉の開閉がスムーズでしかも安価な衛生設備室ユニット１を提供することができる。即ち、上記擦り問題についても解決されているが、この点については、更に詳しく説明する。
【００１８】
図３は、図１のＢ−Ｂ要部断面図であるので、この図の扉３３は、扉を開き切った場合の先端部の断面であり、従って、図３の扉下端面３４は、図２の場合と同様に扉先端下端面３５になる。床面外縁２１の高さは、図２でも図３でも略同じであるので、この面から扉先端下端面３５までの寸法、即ち図２のＣ寸法と図３のＤ寸法とは、本来略同じ寸法になるはずである。従って、図２において下枠３１と扉先端下端面３５との間に適切な間隔が保たれているなら、床面外縁２１から内側の幅数センチメートル乃至十数センチメートルの範囲を、一般勾配部分２２よりも急勾配の内向きの急斜面２３としないで、図３に二点鎖線で示すように、一般勾配部分２２と同じ勾配としても、扉３３を開き切った場合の扉先端部の下部の床面は、勾配により床面外縁２１よりも多少とも低くなっているので、扉先端下端面３５と床面とが擦ることはないはずである。
【００１９】
しかし現実には、衛生設備室ユニット１を構成する各部材の全てが設計通りの正確な寸法形状で、かつ、組立施工誤差も皆無という、理想的な状況ばかりではなく、各部材の寸法形状や組立施工に多少の誤差を伴うのは、やむを得ないことであるが、このような場合には、Ｄ寸法がＣ寸法よりかなり小さくなる場合もありうる。
具体的な例を示すと、図１において、出入口枠３の上部が浴槽６側に多少傾いていたり、出入口枠３は鉛直でも、上側の丁番の軸心が、下側の丁番の軸心より浴槽６側にずれているなど、上下の丁番の軸心を結ぶ総合軸心が鉛直より浴槽６側に倒れていると、扉３３も浴槽６側に倒れることになり、扉を開き切った場合には、扉先端下端面３５が、正規の位置より下がることになる。即ち、Ｄ寸法がＣ寸法よりかなり小さくなり、扉先端下端面３５が床面と擦る状況が発生する。なお、扉３３の自重やその他の荷重、丁番の摩耗などの経時変化が加わると、当初は問題なくても、次第に不具合が生じてくることもあるし、当初からの不具合が徐々に拡大することもある。
【００２０】
又、図２に示すように、扉水密手段３６、本実施形態では水密パッキン３６１が扉３３に取り付けられており、扉３３を閉じた状態では、水密パッキン３６１が下枠３１に弾接する、言い換えれば擦ることにより水密性を保つ構造の場合には、図２において、床面外縁２１から内側の幅数センチメートル乃至十数センチメートルの範囲を、一般勾配部分２２よりも急勾配の急斜面２３としないで、二点鎖線で示すように、一般勾配部分２２と同じ勾配とすると、下枠３１の内側端と略同一高さの床面外縁２１よりいくらも低くない床面が、かなり広い範囲に渉って広がることになり、このかなり広い範囲で、水密パッキン３６１と床面とが擦ることになる。経時に伴う不具合の発生や拡大は、前述の場合と同様である。
【００２１】
しかし、本実施形態では、床面外縁２１から内側の幅数センチメートル乃至十数センチメートル、例えば５センチメートルの範囲を、一般勾配部分２２よりも急勾配、例えば１０分の１程度の内向きの急斜面２３としたので、図３に示すように、扉３３を開き切った場合の扉先端部の下部の床面と扉先端下端面３５との隙間は、全面が一般勾配なら設計通りでもＥ寸法であるが、本実施形態では、これより遙かに大きいＦ寸法となり、扉先端下端面３５が床面と擦るおそれはない。
【００２２】
又、図２の場合においても、本実施形態では、床面は出入口枠３から遠ざかるに従って急激に低くなる、即ち、扉３３を開くに従って、扉先端下端面３５と床面との隙間は急激に大きくなるので、広い範囲で水密パッキン３６１と床面とが擦って、不愉快な思いをするおそれもない。
【００２３】
又、本実施形態では、せり上がり丁番を使う必要がないので、扉３３の開閉はスムーズで、コストの高騰を招くこともない。
即ち、所期の目的を達成できる。
【００２４】
なお、本実施形態では、扉３３を開き切った際に扉先端部が位置する部分、即ち図１の△印Ｐを中心とした部分の床面外縁２１にも出入口枠３が取り付けられるようになっているが、この部分に出入口枠３が取り付けできない場合でも、この部分の床面外縁２１を、出入口枠３を設けることができる部分の床面外縁２１と同様の高さとし、その内側を同様の急斜面２３にすることにより、同様の効果を得ることができる。
【００２５】
図４は、本発明の第２実施形態の、第１実施形態でのＡ−Ａに相当する位置での要部断面図である。
【００２６】
本実施形態では、防水床パン２の急斜面２３の少なくとも一部を、室内外周部に設けられた排水溝５の溝蓋５１の上面で代替した。言い換えると、溝蓋５１の床面外縁２１に相当する部分、即ち蓋上面外縁５２をも、排水溝５がない場合の床面外縁２１と略同じ高さとし、その内側を、急斜面２３と同等の内向きの急勾配面、即ち蓋急斜面５３とした。
従って、第１実施形態と同様の目的を、床面２の外周部に排水溝５を設けた衛生設備室ユニット１でも達成する事ができる。
【００２７】
なお、図４では、溝蓋５１上面全体を蓋急斜面５３としたが、溝蓋５１の外側寄りの一部分のみを急勾配とするも、溝蓋５１だけでなく、防水床パン２の外側寄りの一部分を含めて急勾配とするも任意である。
又、第１実施形態乃至第２実施形態では、防水床パン２を浴槽とは別体のものとしたが、浴槽と洗い場とを一体的に成形した、いわゆる洗い場付き浴槽であっても良い。
なお、第１実施形態及び第２実施形態は、あくまで一例を示すものであり、注記したことは勿論、各注記以外にも、実施形態の例示によって、請求項１及び２に、構成、形状、仕様など、いかなる制限をも加えるものではないことは言うまでもない。

【発明の効果】
本発明は上記構成により次の効果を発揮する。
【００２９】
本発明の請求項１記載の衛生設備室ユニットでは、少なくとも出入口枠を設けることができる部分の床面外縁が、全長に渉って略同一高さに形成された防水床パンを採用したので、同一の防水床パンを使用しながら、いくつかの所定の出入口枠取付位置から任意の位置を選択でき、かつ、出入口部段差に関するバリアフリー仕様を実現することができる。
又、出入口枠の下枠と前記床面外縁との段差を微小にし、この床面外縁から内側の幅数センチメートル乃至十数センチメートルの範囲を、当該範囲に連続的に接続する他の傾斜した床面よりも急勾配の内向き斜面とし、扉を開き切った場合の扉先端部が位置する部分の床面外縁が前記出入口枠を設けることができる部分である場合、開き切った扉の先端部よりも床面外縁寄りに、前記範囲の内縁を位置決めしたので、出入口部段差に関する高度なバリアフリー仕様を実現し、かつ、新設時は勿論、時間が経過して扉下端先端部が多少垂下しても、扉と床面とが擦ることのない、扉の開閉がスムーズでしかも安価な衛生設備室ユニットとすることができる。
【００３０】
本発明の請求項２記載の衛生設備室ユニットでは、扉を開き切った際に扉先端部が位置する部分の床面外縁が、出入口枠を設けることができる部分でない場合に、この部分の床面外縁の高さ及びその内側の形状を、出入口枠を設けることができる部分の床面外縁の高さ及びその内側の形状と、略同一高さ、略同一形状に形成したので、このような場合にも、扉先端部が床面と擦るおそれがない。

BACKGROUND OF THE INVENTION
The present invention relates to a sanitary equipment room unit having a waterproof floor pan including a bathtub with a washing place, such as a bathroom unit and a shower room unit, which allows water to flow on the indoor floor surface.
[0002]
[Prior art]
Conventionally, when constructing a sanitary equipment room unit that flows water to the indoor floor surface, such as a bathroom unit or a shower room unit, it is generally provided on a wall-mounted portion that is provided one step above the floor surface around the waterproof floor pan. The wall panel and the entrance / exit frame are assembled, and the ceiling panel is placed thereon.
However, with the recent increase in demand for elderly and disabled people, so-called barrier-free specifications, it is necessary to keep the steps at the entrance / exit part small, so at least the part on which the entrance / exit frame is to be mounted, in other words, the entrance / exit frame placement The part is formed to have substantially the same height as the floor surface, and further to a height one step lower than the floor surface.
[0003]
On the other hand, as for the attachment position of the entrance / exit frame of the sanitary equipment room unit, it is necessary to be able to select an arbitrary position from some predetermined positions based on the positional relationship with other rooms.
However, if the heights of the wall-mounting portion where the entrance / exit frame is attached and the wall-mounting portion where the other wall panel is attached are changed, different waterproof floor pans are required for each predetermined entrance / exit frame attachment position. In other words, the number of types of waterproof floor pans increases, and the number of production types that produce them increases. This not only increases costs and increases production and logistics issues, but also reduces flexibility at the construction site. End up. That is, when a change in the entrance / exit frame mounting position due to the design change or a selection error of the waterproof floor pan occurs, it is necessary to re-order the waterproof floor pan, which leads to a delay in construction and an increase in cost.
[0004]
For this reason, the wall mounting part of the part to which the wall panel is attached is also formed to have the same height as the floor surface and further one step lower than the floor surface in accordance with the height of the wall mounting part of the part to which the entrance / exit frame is attached. However, as in, for example, Japanese Patent No. 2751784 “Unit Bathroom”, the wall mounting portion is a horizontal surface, and has a rising piece called a waterproof rim or the like on the outside, and the wall is placed on the horizontal surface. As shown in the panel and the entrance / exit frame, and in Japanese Patent Laid-Open No. 10-88637 “Waterproof Pan”, the entrance / exit frame is directly placed on the wall mounting portion, and the wall panel is called a wall mounting piece, an auxiliary member, etc. Various shapes and forms have been derived, such as being placed through wall mounting materials.
[0005]
By the way, in a more advanced barrier-free specification, the outer edge of the floor in contact with the entrance / exit frame of the waterproof floor pan and the floor surface of the adjacent room are substantially the same height, and the upper end surface of the lower frame of the entrance / exit frame is the floor surface. The difference in height between the lower one of the outer edge of the floor surface in contact with the entrance / exit frame of the waterproof floor pan and the floor surface of the adjacent room and the upper end surface of the lower frame of the entrance / exit frame is 3 or less. It is required to be less than a millimeter. Therefore, in the sanitary equipment room unit, it is necessary to suppress the difference in height between the outer edge of the floor surface in contact with the entrance / exit frame of the waterproof floor pan and the upper end surface of the lower frame of the entrance / exit frame to a maximum of 3 mm. In order to satisfy this requirement and to be able to select an arbitrary position from a number of predetermined entrance / exit frame mounting positions, at least the outer edge of the floor surface of the waterproof floor pan where the entrance / exit frame can be provided is provided. It is necessary to form the same height over the entire length.
[0006]
Considering that the door tip of the doorway is likely to hang due to its own weight, load during use, wear of hinges, etc., in order to prevent interference with the floor surface, at least the inner door In this case, generally, the floor surface of the waterproof floor pan within the movable range of the door cannot be made higher than the outer edge of the floor surface in contact with the entrance / exit frame. Accordingly, in consideration of the drainage of the floor surface, a drainage gradient from the outer edge of the floor surface toward the inside is provided.
In order to suppress the difference between the outer edge of the floor surface and the upper end surface of the lower frame of the entrance / exit frame to 3 mm or less, generally considering at least the height of the lower frame, at least a part of the lower frame is generally the outer edge of the floor surface. Need to be lower. That is, the wall mounting portion needs to be formed one step lower than the outer edge of the floor surface. However, since it is not impossible to make the height of the lower frame 3 mm or less or omit the lower frame itself, this is not an absolute requirement.
[0007]
In summary, a waterproof floor pan for a sanitary equipment room unit with a high degree of barrier-free specifications, which can be selected from several predetermined entrance / exit frame mounting positions, has at least a floor outer edge on which an entrance / exit frame can be provided. All of them are formed to have substantially the same height, and it is required to provide a drainage gradient toward a floor drain port provided at a position lower than this surface. Furthermore, generally, it is also required that the wall mounting portion provided outside the outer edge of the floor surface on which at least the entrance / exit frame can be provided be formed one step lower than this surface.
In addition, the floor surface outer edge mentioned here includes the upper surface outer edge of the groove cover of the drainage groove provided on the outer peripheral portion of the floor surface.
[0008]
Many waterproof floor pans for sanitary equipment room units that satisfy the above conditions already exist. However, the floor drainage gradient is generally about 1/40 to 1/100, and the part where the door tip is located when the door is fully opened is usually on the outer edge of the floor. Since it becomes a close part, the floor surface height of this part does not become so low from the upper surface of the outer edge of the floor surface. On the other hand, even when the door tip is normal, it tends to be lowered due to its own weight, load during use, wear of hinges, etc. as described above, and the upper and lower sides where the door is attached due to the inclination of the vertical frame of the entrance / exit frame. If the central axis of the hinge is tilted slightly from the vertical line, depending on the direction of the tilt, when the door is opened, the door tip will be lowered.
Therefore, when the door is closed, it normally fits in the entrance / exit frame, and even if the door and the entrance / exit frame do not rub, if the door is opened, the front end of the door will rub against the floor from the time of new installation or Even if there is no problem, there is a problem to be solved, such as the door tip gradually hangs down over time and rubs against the floor surface.
To solve these problems, there is a hinge called a lift hinge or a gravity hinge when the door is opened, but because of the lift mechanism, the door opens and closes, especially the door opening. Another problem has arisen that not only the operation is smooth, but also the cost increases.
[0009]
[Problems to be solved by the invention]
The present invention has been made in order to solve the above-mentioned problems. The object of the present invention is to select an arbitrary position from several predetermined entrance / exit frame mounting positions while using the same waterproof floor pan, and , Advanced barrier-free specifications regarding the level difference of the entrance / exit, that is, a specification in which the difference between the outer edge of the floor surface in contact with the entrance / exit frame and the upper end surface of the lower frame of the entrance / exit frame is 3 mm or less. An object of the present invention is to provide a hygienic equipment room unit that can be smoothly opened and closed without causing the door and the floor surface to rub against each other even if the front end of the door hangs down somewhat.
[0010]
[Means for Solving the Problems]
About the sanitary equipment unit of each claim of this invention, the means given in order to solve the said subject is demonstrated.
[0011]
In the sanitary equipment room unit according to claim 1 of the present invention, while using the same waterproof floor pan, an arbitrary position can be selected from several predetermined entrance / exit frame mounting positions, and barrier-free specifications relating to entrance / exit steps are provided. In order to achieve this, a waterproof floor pan is adopted in which at least the outer edge of the floor surface where the entrance / exit frame can be provided is formed at substantially the same height over the entire length.
In addition, it realizes advanced barrier-free specifications related to the level difference of the entrance and exit, and of course, when it is newly installed, the door and the floor surface will not rub against each other even if time passes and the tip of the door drops slightly. In order to make the opening and closing of the sanitation equipment room unit smooth and inexpensive, the step between the lower frame of the entrance / exit frame and the outer edge of the floor surface is made minute, and the inner width from the outer edge of the floor surface is several centimeters to tens of centimeters The range is defined as an inwardly inclined surface that is steeper than other inclined floor surfaces that are continuously connected to the range, and the outer edge of the floor surface where the door tip is located when the door is fully opened serves as the entrance / exit frame. When it was a part which can be provided, the inner edge of the said range was positioned near the floor surface outer edge rather than the front-end | tip part of the opened door .
[0012]
In the sanitary equipment unit according to claim 2 of the present invention, when the sanitary equipment unit according to claim 1 is insufficient, that is, when the door is fully opened, the portion where the door tip is located may be provided with an entrance / exit frame. In order to prevent the door tip from rubbing against the floor surface even if it is not a part that can be done, the height of the outer edge of the floor surface of this part and the shape of the inner side of the floor edge of the part where the entrance / exit frame can be provided The height and the inner shape thereof are substantially the same height and substantially the same shape.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings of the embodiments.
[0014]
FIG. 1 is a plan view of a sanitary equipment room unit according to the first embodiment of the present invention, FIG. 2 is a cross-sectional view of the AA main part of the first embodiment, and FIG. 3 is B of the first embodiment. It is -B principal part sectional drawing.

In the sanitary equipment room unit 1, the wall panel 4 and the entrance / exit frame 3 are placed on the wall placing portion 24 of the waterproof floor pan 2, and a ceiling panel (not shown) is placed thereon to form a housing, It is completed by placing or attaching instruments such as the bathtub 6 therein. The waterproof floor pan 2 and the wall panel 4 and the entrance / exit frame 3 are joined in a watertight manner by the watertight means 7, that is, the caulking 71 in this embodiment, and the wall panel 4 and the wall panel 4 and the entrance / exit frame 3 are also It is joined by a suitable watertight joining means (not shown).
[0016]
In the sanitary equipment room unit 1 of the present embodiment, the attachment position of the entrance / exit frame 3 can be arbitrarily selected from the attachment positions centering on the portions P, Q, and R in FIG. 1 in addition to the positions shown in FIG. The floor outer edge 21 of the entire circumference of the washing place 25 excluding the bathtub 6 side is formed to have substantially the same height over the entire length, and the width on the inner side from the floor outer edge 21 is A range of centimeters to a few dozen centimeters is defined as an inward slope or steep slope 23 that is steeper than the other floor portion or general slope portion 22.
The wall mounting portion 24 is formed one step lower than the floor surface outer edge 21 of the waterproof floor pan 2 and on the entire circumference. A door 33 is attached to the entrance / exit frame 3, and the watertightness is substantially maintained between the door 33 and the lower frame 31 by a door watertight means 36, in this embodiment a watertight packing 361.
In addition, 32 is a lower-frame upper end surface, and in this embodiment, in order to satisfy a high barrier-free specification, it is restrained from the floor surface outer edge 21 to the height of 3 millimeters or less.
[0017]
In the present embodiment, since it is configured as described above, an arbitrary position can be selected from a number of predetermined entrance / exit frame mounting positions while using the same waterproof floor pan, and a high degree of barrier-free with respect to the entrance / exit step difference. Specification can be realized. This is obvious from the above configuration except for the problem of rubbing against the floor surface when the door 33 is opened and closed.
In addition, the above-described structure allows the opening and closing of the door to be smoothly and inexpensively performed without causing the door 33 and the floor surface to rub even if the door tip portion hangs down over time as well as when it is newly installed. A chamber unit 1 can be provided. That is, although the above-mentioned rubbing problem has been solved, this point will be described in more detail.
[0018]
3 is a cross-sectional view of the main part BB in FIG. 1, the door 33 in this figure is a cross-section of the tip when the door is fully opened, and therefore the lower end face 34 of FIG. Similar to the case of FIG. Since the height of the floor outer edge 21 is substantially the same in both FIG. 2 and FIG. 3, the dimension from this surface to the door tip lower end surface 35, that is, the C dimension in FIG. 2 and the D dimension in FIG. Should have the same dimensions. Therefore, if an appropriate space is maintained between the lower frame 31 and the door tip lower end surface 35 in FIG. 2, the general gradient is set within the range of several centimeters to tens of centimeters inward from the floor outer edge 21. The lower portion of the front end of the door when the door 33 is fully opened, as shown by a two-dot chain line in FIG. Since the floor surface is slightly lower than the floor surface outer edge 21 due to the gradient, the door front end lower end surface 35 and the floor surface should not rub.
[0019]
However, in reality, not only the ideal situation where all the members constituting the sanitary equipment room unit 1 have the exact dimensional shape as designed and there is no assembly work error, but also the dimensional shape of each member It is unavoidable that some errors are involved in the assembly work, but in such a case, the D dimension may be considerably smaller than the C dimension.
As a specific example, in FIG. 1, the upper part of the entrance / exit frame 3 is slightly inclined to the bathtub 6 side, or the entrance / exit frame 3 is vertical, but the upper hinge axis is the axis of the lower hinge. If the center axis that connects the upper and lower hinge axes is tilted from the vertical to the bathtub 6 side, such as being displaced from the center to the bathtub 6 side, the door 33 will also fall to the bathtub 6 side, and the door will open. When it is cut, the lower end face 35 of the door front end is lowered from the normal position. That is, the D dimension is considerably smaller than the C dimension, and the door tip lower end surface 35 rubs against the floor surface. If a change over time such as the dead weight of the door 33, other loads, or wear of the hinge is applied, even if there is no problem at the beginning, a problem may gradually occur, and the problem from the beginning gradually increases. Sometimes.
[0020]
In addition, as shown in FIG. 2, the door watertight means 36, in this embodiment, the watertight packing 361 is attached to the door 33, and when the door 33 is closed, the watertight packing 361 elastically contacts the lower frame 31. In the case of a structure that keeps water tightness by rubbing, in FIG. 2, a range of several centimeters to several tens of centimeters inward from the outer edge 21 of the floor is set to a steep slope 23 that is steeper than the general slope portion 22. However, as shown by a two-dot chain line, if the same gradient as the general gradient portion 22 is used, the floor surface that is not lower than the floor outer edge 21 that is substantially the same height as the inner edge of the lower frame 31 is in a considerably wide range. The water-tight packing 361 and the floor surface rub against each other over a considerably wide range. The occurrence and enlargement of problems with time is the same as described above.
[0021]
However, in the present embodiment, a range of several centimeters to several tens of centimeters in width from the outer edge 21 of the floor surface, for example, 5 centimeters, is inwardly steeper than the general slope portion 22, for example, about 1/10 inward. As shown in FIG. 3, when the door 33 is fully opened, the gap between the floor surface at the lower end of the door tip and the lower end surface 35 of the door tip is as shown in FIG. Although it is a dimension, in this embodiment, it becomes F dimension much larger than this, and there is no possibility that the door front-end lower end surface 35 may rub against a floor surface.
[0022]
Also in the case of FIG. 2, in this embodiment, the floor surface rapidly decreases as the distance from the entrance / exit frame 3 increases. That is, as the door 33 is opened, the gap between the door tip lower end surface 35 and the floor surface increases rapidly. Since it becomes large, there is no possibility that the water-tight packing 361 and the floor surface rub against each other over a wide range, causing unpleasant feelings.
[0023]
Further, in the present embodiment, since it is not necessary to use a lifting hinge, the door 33 can be opened and closed smoothly without causing an increase in cost.
That is, the intended purpose can be achieved.
[0024]
In this embodiment, when the door 33 is fully opened, the entrance / exit frame 3 is also attached to the outer edge 21 of the floor surface where the door tip is located, that is, the portion centering on the Δ mark P in FIG. However, even when the entrance / exit frame 3 cannot be attached to this portion, the floor surface outer edge 21 of this portion has the same height as the floor surface outer edge 21 of the portion where the entrance / exit frame 3 can be provided, and the inside thereof is the same. By using the steep slope 23, a similar effect can be obtained.
[0025]
FIG. 4 is a cross-sectional view of the main part of the second embodiment of the present invention at a position corresponding to AA in the first embodiment.
[0026]
In this embodiment, at least a part of the steep slope 23 of the waterproof floor pan 2 is replaced with the upper surface of the groove lid 51 of the drainage groove 5 provided on the outer periphery of the room. In other words, the portion corresponding to the floor surface outer edge 21 of the groove lid 51, that is, the lid upper surface outer edge 52 is substantially the same height as the floor surface outer edge 21 without the drainage groove 5, and the inside thereof is equivalent to the steep slope 23. An inwardly steep surface, that is, a lid steep slope 53 was used.
Therefore, the same object as that of the first embodiment can be achieved even in the sanitary equipment room unit 1 in which the drainage grooves 5 are provided in the outer peripheral portion of the floor surface 2.
[0027]
In FIG. 4, the entire upper surface of the groove lid 51 is the steep slope 53, but only a portion near the outside of the groove lid 51 is steep, but not only the groove lid 51 but also the outside of the waterproof floor pan 2. A steep slope including a part is optional.
Moreover, in 1st Embodiment thru | or 2nd Embodiment, although the waterproof floor pan 2 was a thing different from a bathtub, what is called a bathtub with a washing place which shape | molded the bathtub and the washing place integrally may be used.
In addition, 1st Embodiment and 2nd Embodiment show an example to the last, and it should be noted that, of course, in addition to each note, the configuration, shape, Needless to say, it does not impose any restrictions on specifications.
[0028]
