Description

【０００１】
【発明の属する技術分野】
本発明は、バスユニット、シャワーユニット又はトイレユニット等の床パンとして使用する防水パンに関する。
【０００２】
【従来の技術】
従来、この種のバスユニットなどにおいては、高齢者などが躓くことなくバスユニット内に出入りしやすいように、また、バスユニット内の防水パンからの水が簡単に出入口を乗り越えないようにしたものとして、図６（ａ）及び（ｂ）に示すように、防水パン１１の出入口付近に溝蓋としてのグレーチング１３を備えた排水溝を凹設して設けることにより出入口の段差を少なくした構造のものが知られている（例えば、実開平１−９０４８６号公報参照）
【０００３】
また、図７（ａ），（ｂ）に示すように、種々のドア取付け位置に対しても一種類の防水パン１１で対応できるように、防水パン１１の全周にグレーチング３を備えた排水溝１１ｅを設け、防水パン１１の床面１１ｂにはドア又はドア枠５が立設可能な１辺から対辺に向けて下り傾斜の排水勾配１２を設けるようにしたバスユニットも知られている（例えば、実開平６−３０２６７号公報参照）。
【０００４】
【発明が解決しようとする課題】
しかしながら、従来の技術で述べたもののうち前者の図６に示した構造においては、出入口が設けられる辺、すなわちドアが立設される辺にのみ排水溝を設ける構造であり、従って種々のドア取付け位置に対応させるためには、各ドア取付け位置専用の防水パンを数種類用意する必要があり、これにより防水パンの成形型も数種類必要となって高価となる問題点を有していた。
【０００５】
一方、後者の図７に示したバスユニットにおいては、種々のドア取付け位置に対応はできるものの、排水溝１１ｅの上縁の両端に対向して形成されグレーチング載置面となる外側グレーチング載置面１１ｃと内側グレーチング載置面１１ｄとの両面が床面１１ｂの排水勾配１２に合わせて下り傾斜に形成されているため、図７（ａ）に示したように防水パン１１の床面１１ｂに設けられた排水勾配１２の傾斜と直交する方向の辺に、出入りするドアを立設するためのドア枠５を取付けた場合には、図７（ｂ）に示すように、排水勾配１２の始点側である最高部位置すなわち入口の一方の隅ではドア枠５とグレーチング３上面との段差は小さく、又、排水勾配１２の終点側となる最低部位置すなわち入口の他方の隅ではドア枠５とグレーチング３上面との段差は大きくなる。
従って、浴室への出入りに有利な広いドア開口幅になればなるほど、ドア枠５とグレーチング３上面とにおける最低部位と最高部位との段差は大きくなるのである。
よって、図７に示した構造のものにおいてもドアの立設位置によっては必ずしも高齢者などが躓くことなく出入りしやすい小さな段差にはならず、種々のドア取付け位置でも略一定の小さな段差にするためには、前者と同様に各ドア取付け位置専用の防水パンを数種類用意する必要が生じて、これに伴い防水パンの成形型も数種類用意しなければならず高価となるという問題点を有していたのである。
【０００６】
本発明は従来の技術の有するこのような問題点に鑑みてなされたもので、浴室などへの出入りに際して入口の跨ぐ高さを低くして人の出入りを容易にするとともに、防水パンにおける床面の排水勾配と直交する辺にドアが取付けられた場合にも出入口段差を小さく且つ略一定にでき、種々のドア取付け位置にも一種類の防水パンで対応できて量産性のある防水パンを安価に提供しようとするものである。
【０００７】
【課題を解決するための手段】
上記目的を達成するために、請求項１記載の発明は、平面視が略方形状の床面に排水勾配が設けられ、該床面の外周縁に立設して形成した水平な壁載置面にドア及び壁体が取付けられ、前記ドアが立設される辺を含む少なくとも３辺の前記床面の周縁に排水口に繋がる排水溝を形成し、該排水溝にグレーチングを載置してなる防水パンであって、前記床面に設けられた排水勾配と直交する辺の前記排水溝の上縁両端には前記防水パンの床面から前記グレーチングの厚さ程度低い位置に形成した外側グレーチング載置面と内側グレーチング載置面とからなるグレーチング載置面が形成され、防水パンの外方となる外側グレーチング載置面は前記水平な壁載置面と略平行となるように、又、防水パンの内方となる内側グレーチング載置面は排水勾配を設けた前記床面と略平行となるように設けられ、該排水溝の対向するグレーチング載置面に前記グレーチングを、該グレーチングの前記防水パンの床面側に位置する部分の上面全体が該床面と略面一となるように載置して前記排水溝の上面を着脱自在に覆ってなることを特徴とする。
【０００８】
請求項２記載の発明は、グレーチングが載置される外側グレーチング載置面と内側グレーチング載置面との両面が床面の排水勾配に合わせて下り傾斜に形成された防水パンであっても、ドアが取付けられる辺にのみ後加工で容易に出入口段差を小さく且つ略一定にできるように、平面視が略方形状の床面に排水勾配が設けられ、該床面の外周縁に立設して形成した水平な壁載置面にドア及び壁体が取付けられ、前記ドアが立設される辺を含む少なくとも３辺の前記床面の周縁に排水口に繋がる排水溝を形成し、該排水溝にグレーチングを載置してなる防水パンであって、前記床面に設けられた排水勾配と直交する辺の前記排水溝の上縁両端には前記防水パンの床面から前記グレーチングの厚さ程度低い位置に形成した外側グレーチング載置面と内側グレーチング載置面とからなるグレーチング載置面が形成され、防水パンの外方となる上記外側グレーチング載置面と防水パンの内方となる上記内側グレーチング載置面は、排水勾配を設けた前記床面と略平行となるように傾斜され、上記外側グレーチング載置面の部分、又は上記グレーチングの下面に装着したスペーサによって該スペーサの上面が前記水平な壁載置面と略平行となるようにされ、前記排水溝の対向するグレーチング載置面に上記グレーチングを、該グレーチングの前記防水パンの床面側に位置する部分の上面全体が該床面と略面一となるように載置して前記排水溝の上面を着脱自在に覆ってなることを特徴とする。
【０００９】
請求項３記載の発明は、一方が略水平に形成され、他方が傾斜して形成されている捩じれたグレーチング載置面に対しても柔軟に追従して載置することができ、また、従来より使用されているグレーチングが使用できるようにするため、請求項１又は２記載の発明において、グレーチングが、角筒状に形成された複数個のボックス構造体と、該ボックス構造体に穿設した孔に挿通して複数個のボックス構造体同士を連結する連結棒と、各ボックス構造体間の前記連結棒に挿通された駒部材とからなり、前記ボックス構造体が連結棒に対して回動自在に装着されたものであることを特徴とする。
【００１０】
本発明は、上記の構成によって、出入口側に位置するグレーチングの上面長手方向の外側はドア下部と略平行となるため、小さく且つ略一定な段差とすることができ、また、排水溝を防水パンのドアが立設される辺を含む少なくとも３辺に連続して設けているため、防水パンのドア取付け位置による防水パン自体の勝手違いがなくなり一種類の防水パンでの対応が可能となる。
【００１１】
【発明の実施の形態】
以下、本発明に係る防水パンの実施形態について、図１乃至図４を参照しながら詳細に説明する。
【００１２】
図１は本発明による防水パンの一実施例を示し、（ａ）は防水パンの平面図、（ｂ）は（ａ）中のグレーチングを取り外した状態におけるＡ−Ａ断面部分の斜視図、図２（ａ）は図１に示した防水パンをバスユニットの床パンとして用いた状態を示す平面図、図２（ｂ）は（ａ）中のＢ−Ｂ断面部分の斜視図、図３（ａ）は本発明において使用するグレーチングの斜視図、図３（ｂ）は（ａ）の部分断面図である。
【００１３】
図１（ａ）において、平面視が略方形状の防水パン１はガラス繊維などを補強材としたＦＲＰで形成され、方形状の床面１ｂには図中矢印の方向に下り傾斜とした排水勾配２が設けられる。図１（ｂ）に示すように防水パン１における床面１ｂの外周縁には立設して水平な壁載置面１ａが形成されている。
上記床面１ｂの全外周の４辺には床面から下方に凹設して排水溝１ｅが形成されるとともに、排水溝１ｅ内には、図１（ａ）中に示すように少なくとも１個の排水口４が穿設して形成され、排水溝１ｅの底部には流入した水が排水口４に向かうように勾配が設けられている。
図１（ａ）中のＡ−Ａ断面部分の斜視図である図１（ｂ）に示すように、排水溝１ｅ上縁の防水パン１の床面１ｂ側（内方側）に位置する側面上部には床面１ｂから後述するグレーチング３の厚さ程度低い位置に内側グレーチング載置面１ｄと、排水溝１ｅ上縁の防水パン１の外方側に位置する側面上部には外側グレーチング載置面１ｃが形成されている。そして、防水パン１の床面１ｂに設けられた排水勾配２と直交する辺における排水溝１ｅは、防水パン１の外方となる外側グレーチング載置面１ｃは前記の水平な壁載置面１ａと平行に、また、防水パン１の内方となる内側グレーチング載置面１ｄは排水勾配２が設けられた床面１ｂと平行となるように形成され、従って、内側グレーチング載置面１ｄの底部からの高さは一方から他方にいくにしたがって外側グレーチング面１ｃよりも段々と低くなるように形成されている。
【００１４】
図２（ａ）は、図１に示した防水パン１の外周縁の壁載置面１ａに壁体８及び防水パン１の床面１ｂの排水勾配２と直交する側の一辺にドアを取付けるためのドア枠５を、さらに上部には天井（図示省略）などを取付けて、内部に浴槽７などを組み込んでバスユニットとして用いる場合の実施例を示す平面図であり、この場合のドアとしては、引戸、折り戸及び框戸などが使用されるが、有効開口の広くとれる引戸を使用するのが好ましい。
【００１５】
図１（ａ）中及び図２（ａ），（ｂ）中に示したように防水パン１の排水溝１ｅの上面開口を覆って載置する排水溝蓋としてのグレーチング３は、図３（ａ）及び（ｂ）に示すように、塩化ビニル樹脂などを用いて押出し成形などにより角筒状に形成したボックス構造体３ａを、各ボックス構造体３ａ間に間隔を保つためのポリプロピレン樹脂などからなる駒部材３ｃを配置して、ポリエチレン樹脂製などからなる柔軟な連結棒３ｂで複数個連結した構造のものが好ましい。
そして、上記グレーチング３は図２（ｂ）に示すように、防水パン１の床面１ｂの排水勾配２の傾斜と直交する方向の辺にドアを立設した場合でも、グレーチング３の二辺ある長手方向の一辺をドア枠５下部と平行すなわち水平に位置させ、他辺を水平方向に対し床面１ｂの排水勾配２と平行な傾斜をもたせる可能となる。
【００１６】
従って、図２（ａ）及び（ｂ）に示すように、洗面室６の床、ドア枠５部分を略面一に形成し、グレーチング３上面及び防水パン１の床面１ｂとを略面一に形成することができるとともに、ドア枠５部分とグレーチング３との段差を小さく且つ略一定な段差とすることができるので、室の出入りが容易になる。
【００１７】
なお、上記の実施例では、防水パン１の形状、すなわち外側及び内側のグレーチング載置面１ｃ、１ｄの傾斜を変えることでグレーチング３の二辺ある長手方向の一辺をドア枠５下部と水平に位置させ、他辺を水平方向に対し床面１ｂの排水勾配２と略平行の傾斜を形成させる構成としたが、本発明は上記実施例に限定されず、図７に従来例として示した外側グレーチング載置面１１ｃと内側グレーチング載置面１１ｄとが同一傾斜を有する形状の防水パン１１であっても、上記実施例と同様の構成とすることができる。
すなわち、図４（ａ）に示すように、グレーチング３で排水溝１ｅを覆ったときに防水パン１の外側に位置する部分のグレーチング３の下面側に、外側グレーチング載置面１ｃに設けられた傾斜の違い分のスペーサ９を予め取付ける構成とするか、又は、図４（ｂ）に示すように、傾斜の違い分の上記スペーサ９を外側グレーチング載置面１ｃ上に予め取付ける構成としてスペーサ９の上面が水平な壁載置面１ａと平行となるようにして、スペーサ９上面をグレーチング３の片側の載置面となるようにする。
【００１８】
図５は本発明の実施例ではないが図に示すように、グレーチング３自体の形状を、グレーチング３の二辺ある長手方向の一辺をドア枠５下部と平行すなわち水平に形成させ、他辺を水平方向に対して防水パン１の排水勾配２を設けた床面１ｂと平行な傾斜となるような形状に形成することによっても、本発明の構成と同様の効果が得られる。
【００１９】
【発明の効果】
本発明による請求項１記載の発明は、平面視が略方形状の床面に排水勾配が設けられ、該床面の外周縁に立設して形成した水平な壁載置面にドア及び壁体が取付けられ、前記ドアが立設される辺を含む少なくとも３辺の前記床面の周縁に排水口に繋がる排水溝を形成し、該排水溝にグレーチングを載置してなる防水パンであって、前記床面に設けられた排水勾配と直交する辺の前記排水溝の上縁両端には前記防水パンの床面から前記グレーチングの厚さ程度低い位置に形成した外側グレーチング載置面と内側グレーチング載置面とからなるグレーチング載置面が形成され、防水パンの外方となる外側グレーチング載置面は前記水平な壁載置面と略平行となるように、又、防水パンの内方となる内側グレーチング載置面は排水勾配を設けた前記床面と略平行となるように設けられ、該排水溝の対向するグレーチング載置面に前記グレーチングを、該グレーチングの前記防水パンの床面側に位置する部分の上面全体が該床面と略面一となるように載置して前記排水溝の上面を着脱自在に覆った構成としたので、防水パンの床面部分からの水がドアの出入口を乗り越えて室外に流出することがないとともに、出入口段差を少なくすることができるので浴室などへの出入りに際して入口の跨ぐ高さが浅くなって人の出入りが容易となり、また、防水パンにおける床面の排水勾配と直交する辺にドアが取付けられた場合にも出入口段差を小さく且つ略一定にできて高齢者や身体に障害がある人が躓くことなく出入室でき、さらに、種々のドア取付け位置にも一種類の防水パンで対応できて量産性のある安価な防水パンの提供が可能となる効果がある。
【００２０】
また、請求項２に記載のように、グレーチング載置面における外側グレーチング載置面が、防水パンの床面の排水勾配に合わせて傾斜され防水パンと一体に形成した外側グレーチング載置面の部分、又はグレーチングの下面に装着したスペーサによって該スペーサの上面が水平な壁載置面と略平行となる構成とすることにより、従来より使用されている防水パンのドアが取付けられる辺にのみ後加工することで容易に出入口段差を小さく且つ略一定にできる。
【００２１】
さらに、請求項３記載のように、グレーチングを、角筒状に形成された複数個のボックス構造体と、該ボックス構造体に穿設した孔に挿通して複数個のボックス構造体同士を連結する連結棒と、各ボックス構造体間の前記連結棒に挿通された駒部材とからなり、前記ボックス構造体が連結棒に対して回動自在に装着された構成とすることにより、従来より使用されているグレーチングが使用できる。

BACKGROUND OF THE INVENTION
The present invention relates to a waterproof pan used as a floor pan such as a bath unit, a shower unit, or a toilet unit.
[0002]
[Prior art]
Conventionally, in this type of bus unit, etc., it was easy for elderly people to get in and out of the bus unit without craving, and water from the waterproof pan in the bus unit did not easily get over the entrance / exit As shown in FIGS. 6 (a) and 6 (b), the drainage groove provided with the grating 13 as a groove cover is provided in the vicinity of the entrance / exit of the waterproof pan 11 to reduce the step at the entrance / exit. Are known (see, for example, Japanese Utility Model Publication No. 1-90486)
[0003]
Further, as shown in FIGS. 7A and 7B, the drainage provided with the grating 3 on the entire periphery of the waterproof pan 11 so as to be able to cope with various door mounting positions with one type of waterproof pan 11. There is also known a bus unit in which a groove 11e is provided, and a floor 11b of the waterproof pan 11 is provided with a downwardly inclined drainage gradient 12 from one side to the opposite side where a door or door frame 5 can be erected (see FIG. For example, see Japanese Utility Model Laid-Open No. 6-30267).
[0004]
[Problems to be solved by the invention]
However, in the structure shown in FIG. 6 of the former technique described in the prior art, the drainage groove is provided only on the side where the doorway is provided, that is, the side where the door is erected. In order to correspond to the position, it is necessary to prepare several types of waterproof pans dedicated to each door mounting position, and thus several types of waterproof pan forming molds are required, resulting in an expensive problem.
[0005]
On the other hand, in the latter bus unit shown in FIG. 7, although it can correspond to various door mounting positions, the outer grating mounting surface which is formed facing both ends of the upper edge of the drainage groove 11e and becomes the grating mounting surface. 11c and the inner grating mounting surface 11d are formed on the floor surface 11b of the waterproof pan 11 as shown in FIG. 7 (a) because both surfaces of the inner grating mounting surface 11d are downwardly inclined to match the drainage gradient 12 of the floor surface 11b. When the door frame 5 for erecting the door to enter and exit is attached to the side in the direction orthogonal to the slope of the drainage gradient 12, the start side of the drainage gradient 12 as shown in FIG. The step between the door frame 5 and the top surface of the grating 3 is small at the highest position, that is, one corner of the entrance, and the lowest position, that is, the other end of the drainage gradient 12, that is, the door frame 5 and the grating at the other corner. Step between the top surface is increased.
Therefore, the wider the door opening width that is advantageous for entering and exiting the bathroom, the greater the difference in level between the lowest part and the highest part in the door frame 5 and the upper surface of the grating 3.
Therefore, even in the structure shown in FIG. 7, depending on the position where the door is erected, there is not necessarily a small step that is easy for an elderly person to go in and out, and a small step that is substantially constant even at various door mounting positions. Therefore, as in the former case, it is necessary to prepare several types of waterproof pans dedicated to each door mounting position, and accordingly, several types of waterproof pan forming molds must be prepared, resulting in an increase in cost. It was.
[0006]
The present invention has been made in view of such problems of the prior art, and makes it easier for people to enter and exit by entering the entrance to the bathroom, etc. Even when a door is mounted on the side perpendicular to the drainage gradient, the entrance and exit steps can be made small and substantially constant, and a variety of waterproof pans can be used with various types of door mounting positions. Is what you want to offer.

【The invention's effect】
According to the first aspect of the present invention, a drainage gradient is provided on a floor surface having a substantially rectangular shape in plan view, and a door and a wall are provided on a horizontal wall mounting surface formed by standing on the outer peripheral edge of the floor surface. A waterproof pan in which a body is attached and drainage grooves connected to a drainage port are formed at the periphery of the floor surface including at least three sides including the side where the door is erected, and grating is placed in the drainage groove. An outer grating mounting surface and an inner side formed at positions lower than the floor surface of the waterproof pan at the upper edge both ends of the drainage groove on the side perpendicular to the drainage gradient provided on the floor surface. A grating mounting surface comprising a grating mounting surface is formed, and an outer grating mounting surface which is an outer side of the waterproof pan is substantially parallel to the horizontal wall mounting surface, and an inner side of the waterproof pan. The inner grating mounting surface is provided with a drainage gradient. The grating is provided so as to be substantially parallel to the surface of the drainage groove, and the upper surface of the portion of the grating located on the floor surface side of the waterproof pan is substantially flush with the floor surface. Since the top surface of the drainage groove is placed so as to be detachable so as to be detachable, water from the floor surface portion of the waterproof pan does not flow out of the door over the doorway of the door, Since the steps at the entrance and exit can be reduced, the entrance stride becomes shallower when entering and leaving the bathroom, making it easier for people to enter and exit, and a door is attached to the side of the waterproof pan perpendicular to the drainage gradient of the floor. The entrance and exit steps can be made small and substantially constant, allowing elderly people and people with physical disabilities to enter and exit without having to crawl. There is an effect that it is possible to provide an inexpensive waterproof bread with.
[0020]
Further, as defined in claim 2, the outer grating mounting surface of the grating mounting surface is inclined in accordance with the drainage gradient of the floor surface of the waterproof pan and is formed integrally with the waterproof pan. Alternatively, the spacer mounted on the lower surface of the grating is post-processed only on the side where the conventionally used waterproof pan door is attached by adopting a configuration in which the upper surface of the spacer is substantially parallel to the horizontal wall mounting surface. By doing so, the entrance / exit step can be made small and substantially constant.
[0021]
Furthermore, as described in claim 3, the grating is inserted into a plurality of box structures formed in a rectangular tube shape and holes formed in the box structures to connect the plurality of box structures together. And a piece member inserted into the connecting rod between the box structures, and the box structure is mounted on the connecting rod so as to be rotatable. Can be used.
