【発明の属する技術分野】
本発明は、ユニットバスの洗い場に関するものであり、詳しくは、バリアフリー構造のユニットバスに適用される洗い場であって、周縁に壁や扉を建込む特定の構造の溝が張出されており、施工性を一層向上させ得るユニットバスの洗い場に関するものである。
【０００２】
【従来の技術】
周知の通り、ユニットバスは、主要な部材がＦＲＰ等で一体成形された耐久性、防水性に富む浴室であり、浴槽に隣接して洗い場が設けられ且つ浴槽および洗い場の周縁に壁や扉が建込まれた構造を有する。昨今のユニットバスは、浴室の出入り口の段差を２０ｍｍ以下に設計した所謂バリアフリー構造のものが主流である。
【０００３】
上記のバリアフリー構造のユニットバスにおいては、扉の下枠（サッシ）を取り付けた状態において出入り口の段差を小さくする関係から、洗い場床面よりも低い位置から壁および扉が立ち上げられる構造の洗い場（樹脂成形品）を使用する必要がある。具体的には、平面形状が長方形の略板状に形成された洗い場であって、浴槽に隣接する１辺部を除く３辺部の周縁に壁や扉を建込む溝が洗い場床面よりも低い高さでそれぞれ張出されたものが使用される（例えば、特許文献１参照。）。
【０００４】
【特許文献１】
特開平１１−７１９２６号公報
【０００５】
上記の様な洗い場を施工する場合、壁や扉は、図５〜図８に示す様に設置される。図５〜図８は、バリアフリー構造のユニットバスにおける洗い場周りの壁や扉の建込み構造を示す図であり、各々、図５は一般的なユニットバスの壁や扉の配置例を示す平面図、図６は従来の洗い場の角部の構造および壁の建込み施工の際に使用される支持部材を示す斜視図、図７は壁が建込まれた状態の従来の洗い場の角部を示す平面図、図８は洗い場の周縁の溝に壁が建込まれた状態を示す縦断面図である。
【０００６】
すなわち、ユニットバスにおいては、図５に示す様に、浴槽（２）及び浴槽（２）の外周部に壁（３）や扉（４）が配置されるが、浴槽（２）に隣接しない洗い場（１）の３辺部の周縁には、各々、壁（３）や扉（４）を建込む溝（１２）が張出されており、斯かる溝（１２）は、図６に示す様に、洗い場（１）の床面よりも低い高さに設定される。
【０００７】
従って、例えば壁（３）を建込む場合は、扉の下枠との高さ調整を図ると共に、壁（３）の下端を確実に支持し且つ壁（３）を正確に立てるため、通常、例えば略角材状の細長の支持部材（５）をスペーサー及び下地材として溝（１２）に配置し、また、洗い場（１）の角部（出隅部）に相当する溝（１２）のコーナー部には、平面形状が略Ｌ字状に形成されたブロック状の角部支持部材（７）をスペーサー及び下地材として配置する。そして、図７及び図８に示す様に、洗い場（１）の角部の施工においては、支持部材（５）及び角部支持部材（７）を利用し、例えば２方向から壁（３）を建込む。
【０００８】
なお、図６及び図８に示す様に、支持部材（５）及び角部支持部材（７）の上面に突起部（５３）及び突起部（７３）をそれぞれ設け、壁（３）の下端部に前記の突起部（５３）及び突起部（７３）に嵌合する嵌合溝（３５）を予め形成することにより、正確に壁（３）を建込むことが出来る。また、図７に示す様に、壁（３）を配置した後は、角部支持部材（７）の外側の角部に柱状のコーナー部材（図示省略）を立設し、壁（３）の側縁同士の突合せ部分を補強する。
【０００９】
【発明が解決しようとする課題】
ところで、上記の様な洗い場（１）においては、ユニットバスの設置状況に応じて扉の位置を適宜決定するため、３辺部に亙って溝（１２）が設けられるが、洗い場（１）の角部（出隅部）に相当する溝（１２）のコーナー部の施工においては、水の溜まりを防止し且つ上記のコーナー部材を立設するため、上記の様な角部支持部材（７）を配置しなけらばならず、その結果、付属部材が多くなり、また、施工性に欠けると言う問題がある。
【００１０】
本発明は、上記の実情に鑑みてなされたものであり、その目的は、バリアフリー構造のユニットバスに適用される洗い場であって、壁や扉の建込み施工にあたり、少ない付属部材で施工性を一層向上させ得る様に改良されたユニットバスの洗い場を提供することにある。
【００１１】
【課題を解決するための手段】
本発明は、バリアフリー構造のユニットバスに適用される洗い場において、その３辺部の周縁に壁または扉を建込む溝を洗い場床面よりも低い高さでそれぞれ張出すと共に、水の溜まりを防止し且つコーナー部材を立設するため、浴槽に隣接する１辺部と平行な他の１辺部の両端を構成する洗い場床面の出隅部の外側に各溝の終端としての膨出部を予め突設した。しかも、膨出部の立上り部分を上記の出隅部から切り離された状態に形成することにより、成形時に生じる割れや変形を防止し、寸法精度を高めた。
【００１２】
すなわち、本発明の要旨は、バリアフリー構造のユニットバスにおいて浴槽に隣接して設置される洗い場であって、樹脂の一体成形品として平面形状が方形の略板状に形成され、かつ、浴槽に隣接する１辺部を除く３辺部の周縁には壁または扉を建込む溝が洗い場床面よりも低い高さでそれぞれ張出されて成り、そして、浴槽に隣接する前記１辺部と平行な他の１辺部の両端を構成する前記洗い場床面の出隅部の外側には、前記各溝の終端を構成する膨出部が突設され、かつ、当該膨出部の立上り部分は、前記出隅部から切り離された状態に形成されていることを特徴とするユニットバスの洗い場に存する。
【００１３】
【発明の実施の形態】
本発明に係るユニットバスの洗い場の一実施形態を図面に基づいて説明する。図１は、本発明に係るユニットバスの洗い場の外観を示す斜視図である。図２は、本発明に係るユニットバスの洗い場における角部の構造を示す斜視図である。図３は、本発明に係るユニットバスの洗い場の他の例における角部の構造を示す斜視図である。図４は、壁が建込まれた状態の本発明に係るユニットバスの洗い場における角部を示す平面図である。なお、図１〜図４中、従来と同様の部位は、図５〜図８におけるのと同様の符号で示し、以下の実施形態の説明においては、図５、図６及び図８を併用する。また、ユニットバスの洗い場を「洗い場」と略記する。
【００１４】
図中に符号（１）にて示す本発明の洗い場は、バリアフリー構造のユニットバスに適用される洗い場であり、図５に示す様に、浴槽（２）に隣接して設置される。洗い場（１）は、浴槽（２）と同様に、通常、耐熱性樹脂を使用したシートモールドコンパウンド、レジントランスファーモールディング、ハンドレイアップ等のＦＲＰ成形法により、一体成形品として形成される。なお、図示しないが、通常、ユニットバスにおいては、浴槽（２）に臨む洗い場（１）の１辺部から浴槽（２）の前面に亙ってエプロンが立ち上げられる。
【００１５】
図１に示す様に、洗い場（１）は、平面形状が長方形などの方形の略板状に形成されており、例えば、浴槽（２）に隣接する当該洗い場の１辺部近傍の略中央に排水口（１１）を備えている。また、洗い場（１）の洗い場床面（１０）は、上記の排水口（１１）に向けて下り傾斜となる様な排水勾配を備えている。そして、バリアフリーの施工に適用するため、浴槽（２）側の上記の１辺部を除く３辺部の周縁には、壁（３）又は扉（４）（図５参照）を建込む溝（１２）が洗い場床面（１０）よりも低い高さでそれぞれ張出される。
【００１６】
図２に示す様に、洗い場（１）の３辺部の周縁に張出された上記の溝（１２）は、扉（４）を設置するための枠材（サッシ）を据え付けた際に前記枠材の上端面が洗い場床面（１０）と略同一高さとなる様に、枠材の高さ分だけ洗い場床面（１０）よりも低い位置に設けられる。具体的には、溝（１２）の底面の位置は、洗い場床面（１０）よりも２０〜３５ｍｍ程度低い位置に設定される。溝（１２）の幅は、上記の枠材が嵌合し得る大きさに設計されるが、通常は１５〜３０ｍｍ程度とされる。
【００１７】
また、図３に示す様に、洗い場（１）の３辺部の各溝（１２）の外周縁には、水返し（１３）が立ち上げられていてもよい。斯かる水返し（１３）は、通常、洗い場床面（１０）よりも高い高さに立ち上げられる。上記の様に、水返し（１３）が立ち上げられている場合には、仮に、扉（４）の枠材や壁（３）の基部から漏水した際も、溝（１２）から外側へ流れ出ることがないため、躯体の床側に対する防水性を一層高めることが出来る。
【００１８】
本発明の洗い場（１）においては、角部における施工性を高めるため、すなわち、壁（３）又は扉（４）を建込む際の施工性を高めるため、図１に示す様に、浴槽（２）に隣接する上記の１辺部と平行な他の１辺部（図１において排水口（１１）がない側の長辺部）の両端を構成する洗い場床面（１０）の出隅部の外側には、各溝（１２）の終端を構成する膨出部（１６）が突設される。
【００１９】
上記の膨出部（１６）は、洗い場（１）の成形時に溝（１２）と共に一体に成形された部位であり、各溝（１２）の端部における水の溜まりを防止し、かつ、壁（３）や扉（４）の突き合わせ部分に前述した様な柱状のコーナー部材を立設するために設けられる。膨出部（１６）の形状は、溝（１２）の端部を構成し且つ上記のコーナー部材を立設し得る限り特に制限はないが、通常、膨出部（１６）の平面形状は、図２及び図３に示す様に、略正方形に形成される。
【００２０】
膨出部（１６）の高さは、２方向から壁（３）の側縁同士または壁（３）の側縁と扉（４）の縦枠とを突き合わせてその突合せ部分にコーナー部材を付設する関係から、洗い場床面（１０）と略同等の高さとされる。すなわち、溝（１２）の底部から膨出部（１６）の立ち上がり高さは約２０〜３５ｍｍに設定される。
【００２１】
ところで、上記の膨出部（１６）については、洗い場床面（１０）と略同等の高さであるから、洗い場（１）の成形時、洗い場床面（１０）と連続的に形成することも考えられる。しかしながら、種々検討の結果、洗い場床面（１０）に連続させて上記の膨出部（１６）を形成した場合には、洗い場床面（１０）側と膨出部（１６）とが極めて小さな断面積の略直線状の部位で連結された状態となるため、成形時に樹脂量の不足から変形が生じたり、型開の際などに連結部分に割れが生じ易いことが確認された。
【００２２】
そこで、本発明の洗い場（１）においては、図２及び図３に示す様に、膨出部（１６）の立上り部分が洗い場床面（１０）の出隅部から切り離された状態に形成されていることが重要である。すなわち、膨出部（１６）は、平面視した場合に洗い場床面（１０）の出隅部から切り離された状態とされる。換言すれば、膨出部（１６）は２つの溝（１２）の端部から立ち上げられ、平面視した場合に略正方形になされた膨出部（１６）において洗い場床面（１０）の出隅部に近接する角部に相当する部分は、前記の出隅部から離間した状態に構成され、洗い場床面（１０）の出隅部と膨出部（１６）との間に隙間（１７）が設けられる。洗い場床面（１０）の出隅部と膨出部（１６）の隙間（１７）の大きさ（最小の隙間距離）は、溝（１２）の終端位置を考慮し、通常は３〜１０ｍｍ程度とされる。
【００２３】
本発明の洗い場（１）を適用したユニットバスにおいては、従来と同様に、図５に示す様に、浴槽（２）、洗い場（１）の周囲に壁（３）及び扉（４）が設置される。そして、洗い場（１）の周縁に壁（３）や扉（４）を建込む場合は、図６に示した様な支持部材（５）が使用される。例えば、洗い場（１）の角部に２方向から壁（３）を建込むには、図４に示す様に、各溝（１２）に支持部材（５）を挿入し、２方向から膨出部（１６）の各側端面に各支持部材（５）を押し当てる様にして配置した後、その上に壁（３）を設置する。また、膨出部（１６）の上部には、前述した様な柱状のコーナー部材を立設し、壁（３）の側縁同士の突合せ部分を補強する。なお、支持部材（５）の形状および壁（３）の下端部の取付構造は、前述した通り、例えば図６及び図８に示す様な形状および構造を採用することが出来る。
【００２４】
上記の様に、本発明の洗い場（１）は、洗い場床面（１０）の出隅部の外側に膨出部（１６）が突設され、３辺部の周縁にそれぞれ張出されて壁（３）又は扉（４）が建込まれる溝（１２）の終端を膨出部（１６）によって構成されているため、壁（３）や扉（４）の建込み施工にあたり、コーナー部に配置する付属部材が必要なく、より少ない付属部材、例えば支持部材（５）の様な付属部材だけで施工することが出来る。しかも、本発明の洗い場（１）は、膨出部（１６）の立上り部分が洗い場床面（１０）の出隅部から切り離された状態に形成されているため、すなわち、洗い場床面（１０）の出隅部と膨出部（１６）との間に隙間（１７）が設けられるため、成形時における割れや変形がなく、より高い強度で且つ高い寸法精度で成形できる。従って、本発明の洗い場（１）を使用した場合には、壁（３）や扉（４）の建込み施工を行うにあたり、施工性を一層向上させることが出来、その結果、施工費も一層低減することが出来る。
【００２５】
【発明の効果】
本発明に係るユニットバスの洗い場によれば、洗い場床面の出隅部の外側に膨出部が突設され、３辺部の周縁にそれぞれ張出されて壁または扉が建込まれる溝の終端を膨出部によって構成されているため、コーナー部に配置する付属部材が必要なく、しかも、膨出部の立上り部分が洗い場床面の出隅部から切り離された状態に形成されており、成形時における割れや変形がなく、より高い強度で且つ高い寸法精度で成形できるため、壁や扉の建込み施工にあたり、施工性を一層向上させることが出来る。

[0002]
[Prior art]
As is well known, the unit bath is a durable and waterproof bathroom whose main members are integrally formed of FRP or the like. A washing place is provided adjacent to the bathtub, and walls and doors are provided around the periphery of the bathtub and the washing place. It has a built-in structure. In recent years, unit baths having a so-called barrier-free structure in which a step at a doorway of a bathroom is designed to be 20 mm or less are mainly used.
[0003]
In the above-mentioned barrier-free unit bath, a washing room having a structure in which walls and doors can be started from a position lower than the floor of the washing room because the height of the entrance is small when the lower frame (sash) of the door is attached. (Resin molded product) must be used. Specifically, in a washing place whose planar shape is formed in a substantially plate-like shape having a rectangular shape, a groove in which a wall or a door is built on the periphery of three sides excluding one side adjacent to the bathtub is larger than the floor of the washing place. Those that are overhanging at a low height are used (for example, see Patent Document 1).
[0004]
[Patent Document 1]
JP-A-11-71926 [0005]
When constructing the washing place as described above, walls and doors are installed as shown in FIGS. FIGS. 5 to 8 are views showing a built-in structure of a wall and a door around a washing place in a unit bath having a barrier-free structure, and FIG. 5 is a plan view showing an example of arrangement of walls and doors of a general unit bath. Fig. 6 and Fig. 6 are perspective views showing a structure of a corner of a conventional washing place and a support member used for construction of a wall, and Fig. 7 shows a corner of the conventional washing place with a built-in wall. FIG. 8 is a longitudinal sectional view showing a state in which a wall is built in a groove on the periphery of the washing place.
[0006]
That is, in the unit bath, as shown in FIG. 5, the tub (2) and the wall (3) and the door (4) are arranged on the outer periphery of the tub (2), but the washing area not adjacent to the tub (2). At the periphery of the three sides of (1), a groove (12) for setting up the wall (3) and the door (4) is projected, and the groove (12) is as shown in FIG. The height is set lower than the floor of the washing place (1).
[0007]
Therefore, for example, when the wall (3) is to be built, the height of the wall (3) is adjusted with the lower frame of the door, the lower end of the wall (3) is securely supported, and the wall (3) is erected accurately. For example, an elongated support member (5) having a substantially square shape is disposed in the groove (12) as a spacer and a base material, and a corner of the groove (12) corresponding to a corner (outside corner) of the washing place (1). , A block-shaped corner support member (7) having a substantially L-shaped planar shape is disposed as a spacer and a base material. As shown in FIGS. 7 and 8, in the construction of the corner of the washing place (1), the wall (3) is used from, for example, two directions by using the support member (5) and the corner support member (7). Stand up.
[0008]
As shown in FIGS. 6 and 8, a projection (53) and a projection (73) are provided on the upper surface of the support member (5) and the corner support member (7), respectively, and the lower end of the wall (3) is provided. The wall (3) can be accurately built by forming the fitting groove (35) to be fitted in the protrusion (53) and the protrusion (73) in advance. Further, as shown in FIG. 7, after the wall (3) is arranged, a columnar corner member (not shown) is erected on the outer corner of the corner support member (7), and the wall (3) is erected. Reinforce the butted part between the side edges.
[0009]
[Problems to be solved by the invention]
By the way, in the washing place (1) as described above, a groove (12) is provided over three sides in order to appropriately determine the position of the door according to the installation condition of the unit bath. In the construction of the corner portion of the groove (12) corresponding to the corner portion (outward corner portion) of the above, in order to prevent accumulation of water and erect the corner member, the corner support member (7) ) Must be arranged, and as a result, there is a problem that the number of attached members increases and the workability is lacking.
[0010]
The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to provide a washing room applied to a unit bath having a barrier-free structure, and to construct walls and doors with a small number of attached members, thereby improving the workability. It is an object of the present invention to provide an improved unit bath washing place so as to further improve the washing condition.
[0011]
[Means for Solving the Problems]
The present invention provides, in a washing place applied to a unit bath having a barrier-free structure, a groove for installing a wall or a door on the periphery of three sides thereof at a height lower than the floor of the washing place, and a pool of water. In order to prevent and erect a corner member, a bulging portion as an end of each groove is formed outside a protruding corner of a floor of a washing place constituting both ends of another side parallel to one side adjacent to the bathtub. Was provided in advance. In addition, by forming the rising portion of the bulging portion in a state separated from the above-mentioned protruding corner portion, cracks and deformation occurring during molding are prevented, and dimensional accuracy is improved.

Outside the corners of the floor of the washing area constituting both ends of the other one side portion, bulging portions constituting the ends of the grooves are protruded, and the rising portions of the bulging portions are , Which is formed so as to be separated from the protruding corner portion.
[0013]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of a unit bath washing place according to the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing the appearance of a unit bath washing place according to the present invention. FIG. 2 is a perspective view showing a structure of a corner portion in a unit bath washing place according to the present invention. FIG. 3 is a perspective view showing a structure of a corner portion in another example of the unit bath washing place according to the present invention. FIG. 4 is a plan view showing a corner of a unit bath according to the present invention in a state where a wall is built in a washing place. 1 to 4, the same parts as those in the related art are denoted by the same reference numerals as those in FIGS. 5 to 8, and FIGS. 5, 6, and 8 are used together in the following description of the embodiments. . The washing area for the unit bath is abbreviated as “wash area”.
[0014]
The washing place of the present invention indicated by reference numeral (1) in the figure is a washing place applied to a unit bath having a barrier-free structure, and is installed adjacent to a bathtub (2) as shown in FIG. Like the bathtub (2), the washing place (1) is usually formed as an integrally molded product by an FRP molding method such as sheet mold compound, resin transfer molding, and hand lay-up using a heat-resistant resin. Although not shown, in a unit bath, an apron is usually set up from one side of the washing place (1) facing the bathtub (2) to the front of the bathtub (2).
[0015]
As shown in FIG. 1, the washing place (1) is formed in a substantially plate-like shape having a rectangular shape such as a rectangular plane, and is, for example, substantially at the center near one side of the washing place adjacent to the bathtub (2). A drain port (11) is provided. Further, the washing floor (10) of the washing place (1) is provided with a drainage slope that is inclined downward toward the drainage port (11). Then, in order to apply to barrier-free construction, a groove for building a wall (3) or a door (4) (see FIG. 5) is formed around the periphery of the three sides except the above-mentioned one side on the bathtub (2) side. (12) are respectively protruded at a lower height than the washing floor (10).
[0016]
As shown in FIG. 2, the above-mentioned groove (12) protruding around the periphery of the three sides of the washing place (1) is used when the frame (sash) for installing the door (4) is installed. The frame material is provided at a position lower than the washing floor (10) by the height of the frame material so that the upper end surface of the frame material is substantially the same height as the washing floor (10). Specifically, the position of the bottom surface of the groove (12) is set to a position lower by about 20 to 35 mm than the floor (10) of the washing place. The width of the groove (12) is designed to be large enough to fit the above-mentioned frame material, but is usually about 15 to 30 mm.
[0017]
Further, as shown in FIG. 3, a water return (13) may be set up on the outer peripheral edge of each groove (12) on three sides of the washing place (1). Such a water return (13) is usually raised to a height higher than the washing floor (10). As described above, when the water return (13) is raised, even if water leaks from the frame material of the door (4) or the base of the wall (3), it flows out from the groove (12) to the outside. Therefore, the waterproofness of the frame on the floor side can be further enhanced.
[0018]
In the washing place (1) of the present invention, in order to enhance the workability at the corners, that is, to improve the workability when the wall (3) or the door (4) is built, as shown in FIG. Protruding corners of the washing floor (10), which constitute both ends of the other side (long side without the drain (11) in FIG. 1) parallel to the above one side adjacent to 2). A bulge (16), which constitutes the end of each groove (12), protrudes from the outside.
[0019]
The bulging part (16) is a part integrally formed with the groove (12) at the time of forming the washing place (1), and prevents the accumulation of water at the end of each groove (12), and also prevents the wall from swelling. It is provided to erect the columnar corner member as described above at the butted portion of (3) or the door (4). The shape of the bulging portion (16) is not particularly limited as long as it constitutes the end of the groove (12) and the above-mentioned corner member can be erected. As shown in FIGS. 2 and 3, it is formed in a substantially square shape.
[0020]
The height of the bulging portion (16) is such that the side edges of the wall (3) or the side edges of the wall (3) and the vertical frame of the door (4) are abutted from two directions, and a corner member is attached to the abutting portion. Therefore, the height is approximately the same as the washing floor (10). That is, the rising height of the bulging portion (16) from the bottom of the groove (12) is set to about 20 to 35 mm.
[0021]
By the way, the bulging portion (16) has substantially the same height as the washing floor (10), so that it should be formed continuously with the washing floor (10) when forming the washing basin (1). Is also conceivable. However, as a result of various studies, when the above-mentioned bulging portion (16) is formed so as to be continuous with the washing floor (10), the side of the washing floor (10) and the bulging portion (16) are extremely small. Since it was connected at a substantially linear portion of the cross-sectional area, it was confirmed that deformation occurred due to insufficient amount of resin at the time of molding, and that the connected portion was easily cracked at the time of opening the mold.
[0022]
