【発明の属する技術分野】
本発明は、浴室のドア下枠に関し、更に詳しくは洗い場パンの床面を脱衣室の床面とほぼ同じ高さに形成し、両床面間の段差を解消したバリアフリー浴室の出入口部に設置するドア下枠に関するものである。
【０００２】
【従来の技術】
従来この種の浴室のドア下枠としては、例えば排水溝を兼用するよう樋形状に形成されているものがある（例えば特許文献１参照）。
又この種の浴室の出入口構造としては、ドア下枠を板状に形成して平面化し、洗い場パンの延長部に重ね合わせて水密状に設けることを内容とする、本出願人の提案に係る先行事例がある（未公開特許出願１参照）。

特開２０００ー８７１６号公報
【未公開特許出願１】
特願２００１ー１６０７８５号
【０００４】
【発明が解決しようとする課題】
特許文献１に記載のドア下枠の場合は、上記の通り、樋形状に形成されているため、ドア下枠の構造や形態が複雑化し、構成部品数の増加を招き、コストが割り高になり、又シールド箇所が増えて施工に手間暇がかかり易かった。又この従来品の場合は、樋形状のため設置高さを大きく取られ、その分、ドアの高さや天井の高さが低く抑えられることになる、という問題があった。
そこで本出願人は、これらの問題を解決できるよう、未公開特許出願１に記載の発明を提案した。しかしながらこの提案に係るドア下枠は、板状に形成されているため、外力の作用を受けて捩れや歪み等の変形を来たす惧れがあった。又これによると、洗い場パンの上に重ね合わせたとき位置ずれし、ネジ孔を合わせにくくなる等、取付作業や位置決め作業がしにくい、という不便があった。
【０００５】
本発明は、このような従来技術の問題点に鑑み、提案されたものである。
従って本発明の技術的課題は、板状に形成したドア下枠であって、捩れ等の変形を来たすことを防止でき、又取付作業や位置決め作業を簡単化、迅速化できるよう形成した浴室のドア下枠を提供することにある。
【０００６】
【課題を解決するための手段】
本発明は、上記の課題を解決するために、次のような技術的手段を採る。
【０００７】
即ち本発明は、図１等に示されるように、洗い場パン１の床面１ａが脱衣室３の床面３ａとほぼ同じ高さに形成されている浴室のドア下枠であって、ドア２との係合部４を有して板状に形成され、洗い場パン１の床面１ａに重ね合わされる下面７に、洗い場パン１の脱衣室３側の側端部１ｂに嵌め付けるための嵌め付け部８が鉤形に形成されていることを特徴とする（請求項１）。
【０００８】
本発明の場合、ドア２は、開き戸に限定されるものではなく、引き戸や折れ戸等が含まれる。又ここで、ドア２との係合部４とは、ドア２が引き戸や折れ戸の場合はドア２を案内するレールを、又ドア２が開き戸の場合はドア２の下部を当接させたり、下部に取り付けたパッキンを入り込ませたり、係止させる箇所を意味する。又ここで、板状に形成され、とは、床下に出っ張ることなく、しかも出入時に段差を感じさせない程度に平たく薄い状態に形成されている、ということを意味する。又鉤形に形成されている、とは、嵌め付け部８が下面７との間でコの字形の嵌め込み口を形作るよう形成されている、ということを意味する。
【０００９】
而して本発明の場合、係合部４は、図３等に示されるように、縦断面略Ω形の孔開きレール状に形成されているのが好ましい（請求項２）。
【００１０】
なぜならこれによると、係合部４にドア２の案内機能と、ネジ止め孔としての機能を持たせることができ、ドア下枠を平板状に薄くしても、従来通り、側方から容易にネジ止めできるからである。
【００１１】
又本発明は、図５等に示されるように、係合部４がレール状に形成され、この係合部４が戸車１１の蟻溝形環状溝１２と係合する蟻形に形成されているのが好ましい（請求項３）。
【００１２】
なぜならこれによると、係合部４の高さＨ１が低い場合でも、戸車１１と係合部４にかかりがあるため、戸車１１の脱輪を防止でき、側方からの衝撃でドア２が外れることを防止できるからである。
【００１３】
又本発明の捩れ防止の課題を達成する他の構成としては、図７に示されるものがある。即ちこの本発明品は、洗い場パン１の床面１ａが脱衣室３の床面３ａとほぼ同じ高さに形成されている浴室のドア下枠であって、ドア２との係合部４を有して板状に形成されている上面部１３と、洗い場パン１の立ち下げ壁１ｃに当接させるため上面部１３の片側に上面部１３と直交状に形成されている側面部１４と、この側面部１４の下端と上面部１３の脱衣室３側との間に傾斜状に形成されている傾斜面部１５とでなる縦断面略直角三角形状の枠部１６を備えて形成されていることを特徴とする（請求項４）。
【００１４】
ここで、ドア２及び係合部４の意味は、上例の場合と同様である。側面部１４の高さは任意であるが、床下の高さを大きくとることがないよう、例えば３０〜５０ｍｍ程度に選定される。
【００１５】
この本発明の場合は、洗い場パン１の立ち下げ壁１ｃに側面部１４をネジ止めするため、ネジ止め作業用の開口部１７が傾斜面部１５に形成されているのが好ましい（請求項５）。
【００１６】
なぜならこれによると、捩れ等の変形に耐える強度を有しながら、洗い場パン１の立ち下げ壁１ｃに固定する作業を側方から容易にできるからである。本発明の場合、開口部１７の大きさ、形状、位置等は任意である。
【００１７】
又本発明の場合は、図８、図９に示されるように、ドア２の縦枠９が嵌め付けられるベース部材２０を両端部に起立状に備えて形成されているのが好ましい（請求項６）。
【００１８】
なぜならこれによると、ベース部材２０に嵌め込むことで縦枠９を立設でき、縦枠９の設置作業を容易化できるからである。
【００１９】
ところでこの種のバリアフリー浴室の場合、出入口のレールは段差を感じさせない程度に形成する必要があるため、その高さは例えば３ｍｍ程度に選定されるのが通例である。そのため従来この種の浴室のドア下枠は、側方から大きな衝撃が加わると戸車を脱輪させ、ドア２としての引き戸がレールから外れ易いものであった。
而してこの種の問題を解決できるドア下枠としては、例えば図５、図６に示されるものがある。即ちこの本発明品は、洗い場パン１の床面１ａが脱衣室３の床面３ａとほぼ同じ高さに形成されている浴室のドア下枠であって、ドア２の戸車１１と係合するレール状係合部４を有して板状に形成され、この係合部４が戸車１１の蟻溝形環状溝１２と係合する蟻形に形成されていることを特徴とする（請求項７）。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a lower frame of a bathroom, and more specifically, a floor of a washing pan is formed at substantially the same height as a floor of a dressing room, and a door-to-door portion of a barrier-free bathroom in which a step between both floors is eliminated. It relates to the door lower frame to be installed.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, as a lower frame of a door of a bathroom of this type, for example, there is a type formed in a gutter shape so as to double as a drainage groove (for example, see Patent Document 1).
Further, as the entrance / exit structure of this type of bathroom, the present invention proposes that the lower frame of the door is formed in a plate shape to be flattened, and provided in a watertight manner by being superimposed on the extension of the washing pan. There is a preceding case (see Unpublished Patent Application 1).
[0003]
[Patent Document 1]
JP 2000-8716 [Unpublished patent application 1]
Japanese Patent Application No. 2001-160785 [0004]
[Problems to be solved by the invention]
In the case of the door lower frame described in Patent Literature 1, as described above, since the shape is formed in a gutter shape, the structure and form of the door lower frame are complicated, the number of components is increased, and the cost is increased. In addition, the number of shield points increased, and construction was easy and time-consuming. In addition, in the case of this conventional product, there is a problem that the installation height is large due to the gutter shape, and the height of the door and the height of the ceiling are correspondingly reduced.
Therefore, the present applicant has proposed the invention described in Unpublished Patent Application 1 so as to solve these problems. However, since the door lower frame according to this proposal is formed in a plate shape, there is a fear that the door lower frame may be deformed such as torsion or distortion under the action of an external force. In addition, according to this, there is an inconvenience that the mounting operation and the positioning operation are difficult, for example, the position shifts when it is superimposed on the washing pan and it becomes difficult to align the screw holes.
[0005]
The present invention has been proposed in view of such problems of the related art.
Therefore, a technical problem of the present invention is a door lower frame formed in a plate shape, which can prevent deformation such as twisting, and can simplify and speed up a mounting operation and a positioning operation of a bathroom. To provide a door frame.
[0006]
[Means for Solving the Problems]
The present invention employs the following technical means in order to solve the above problems.
[0007]
That is, as shown in FIG. 1 and the like, the present invention is a bathroom door lower frame in which the floor 1a of the washing pan 1 is formed at substantially the same height as the floor 3a of the dressing room 3, and Is formed in a plate-like shape having an engaging portion 4 with the bottom surface 1a of the washing pan 1, and is fitted to the side end 1b of the washing pan 1 on the undressing room 3 side. The attachment portion 8 is formed in a hook shape (claim 1).
[0008]
In the case of the present invention, the door 2 is not limited to the hinged door, but includes a sliding door, a folding door and the like. Here, the engaging portion 4 with the door 2 refers to a rail for guiding the door 2 when the door 2 is a sliding door or a folding door, and to contact the lower part of the door 2 when the door 2 is an opening door. , Means a place where the packing attached to the lower part is inserted or locked. Here, being formed in the shape of a plate means that it is formed so as to be flat and thin without protruding under the floor and not to feel a step when entering and exiting. Further, being formed in a hook shape means that the fitting portion 8 is formed so as to form a U-shaped fitting opening with the lower surface 7.
[0009]
Thus, in the case of the present invention, as shown in FIG. 3 and the like, it is preferable that the engaging portion 4 is formed in the shape of a perforated rail having a substantially vertical Ω-shaped cross section (claim 2).
[0010]
Because, according to this, the engaging portion 4 can have the function of guiding the door 2 and the function of a screw hole, and even if the door lower frame is thinned into a flat plate shape, it can be easily sideways as before. Because it can be screwed.
[0011]
In the present invention, as shown in FIG. 5 and the like, the engaging portion 4 is formed in a rail shape, and the engaging portion 4 is formed in a dovetail shape which engages with the dovetail-shaped annular groove 12 of the door wheel 11. (Claim 3).
[0012]
Because, according to this, even when the height H1 of the engaging portion 4 is low, since the door wheel 11 and the engaging portion 4 are engaged, the door wheel 11 can be prevented from coming off, and the door 2 is detached by a side impact. This is because that can be prevented.
[0013]
FIG. 7 shows another configuration for achieving the object of the present invention for preventing torsion. That is, the product of the present invention is a bathroom door lower frame in which the floor 1a of the washing pan 1 is formed at substantially the same height as the floor 3a of the dressing room 3, and the engaging portion 4 with the door 2 is provided. An upper surface portion 13 having a plate-like shape, a side surface portion 14 formed on one side of the upper surface portion 13 to be in contact with the falling wall 1c of the washing pan 1, and being formed orthogonal to the upper surface portion 13; A frame section 16 having a substantially right-angled triangular cross section formed by an inclined surface section 15 formed in an inclined shape between the lower end of the side surface section 14 and the undressing room 3 side of the upper surface section 13. (Claim 4).
[0014]
Here, the meanings of the door 2 and the engaging portion 4 are the same as those in the above example. The height of the side portion 14 is arbitrary, but is selected to be, for example, about 30 to 50 mm so that the height under the floor is not increased.
[0015]
In the case of the present invention, an opening 17 for screwing work is preferably formed in the inclined surface portion 15 in order to screw the side surface portion 14 to the falling wall 1c of the washing pan 1 (claim 5). .
[0016]
This is because, according to this, the work of fixing the washing pan 1 to the falling wall 1c can be easily performed from the side while having strength to withstand deformation such as twisting. In the case of the present invention, the size, shape, position, and the like of the opening 17 are arbitrary.
[0017]
In the case of the present invention, as shown in FIGS. 8 and 9, it is preferable that the base member 20 to which the vertical frame 9 of the door 2 is fitted is provided at both ends in an upright state. 6).
[0018]
This is because, according to this, the vertical frame 9 can be erected by being fitted into the base member 20, and the installation work of the vertical frame 9 can be facilitated.
[0019]
By the way, in the case of this type of barrier-free bathroom, the rails at the entrance and exit must be formed so as not to feel a step, so that the height is usually selected to be, for example, about 3 mm. For this reason, the door lower frame of this type of bathroom has conventionally been such that when a large impact is applied from the side, the door wheel is released, and the sliding door as the door 2 is easily detached from the rail.
FIGS. 5 and 6 show examples of door lower frames that can solve this kind of problem. That is, the present invention product is a bathroom door lower frame in which the floor 1a of the washing pan 1 is formed at substantially the same height as the floor 3a of the dressing room 3, and engages with the door wheel 11 of the door 2. It is formed in a plate shape having a rail-shaped engaging portion 4, and the engaging portion 4 is formed in a dovetail shape that engages with the dovetail-shaped annular groove 12 of the door wheel 11. 7).
