Description

【０００１】
【発明の属する技術分野】
本発明は、バリアフリー住宅における浴室出入り部下枠の段差解消と傾斜ステップの取付手段に特徴を有する浴室引き戸の下枠装置に関する。
【０００２】
【従来の技術】
従来、住宅の公的融資基準のひとつとしてバリアフリー住宅があるが、浴室においては、グレーチング、スノコなどを洗い場に設置し、段差解消手段としている。最近、浴室内の清掃を容易にするため、グレーチングなどを削除することが検討されている。
【０００３】
【発明が解決しようとする課題】
従来のグレーチングレスの浴室は、引き戸下枠前に比較的細い溝を設けたり、浴室床面の一部を切り欠いて、この切り欠きに別体のピットを接続して排水させる構造をとっており、上記細い溝を設けるタイプでは細いグレーチングを必要とし、また、後付ピットタイプではピット部のメンテナンスが必要となる。このような状況のもとで、本発明者等は浴室出入り部下枠の浴室側にスロープ（傾斜ステップ）を付設することを提案した（特願平１１−１６４６１７号）。本発明は、該提案に改良を加えたもので、その課題とするところは、浴室にグレーチングやスノコを設置せずに、浴室引き戸本体の沓摺高さをできる限り低くした状態で傾斜ステップを付設して出入りし易くし、更に、新設・既設の浴室下枠装置に拘わらず、傾斜ステップ２５を下枠側に容易に且つ簡単な操作で着脱可能とすることにある。
【０００４】
【課題を解決するための手段】
住宅の公的融資基準をクリアーする沓摺高さが２０mm以下であることから、沓摺高さ、換言すれば、浴室床面に対する下枠上面の段差を若干、即ち、２０mm以下とし、車椅子などでも使用上問題とならないレベルで段差を解消するための傾斜ステップ２５を設ける。そして、請求項１記載の傾斜ステップ付き浴室下枠装置は、傾斜ステップ２５に設けられた連結部材Ａを介して、傾斜ステップ２５の室外側を下枠２０側に着脱可能に連結させ、連結部材Ａとして、下枠２０の室内側に連結ビス２９，２９を植設し、該連結ビス２９，２９に傾斜ステップ２５の室外側端縁に穿設したビス係合スリット２５ｇ，２５ｇを係合可能に形成することを特徴とする。
【０００５】
【発明の実施の形態】
【実施例１】
実施例１は、傾斜ステップ付き浴室下枠装置の一例を説明をするものであり、図２に示すような浴室用の三枚引戸からなる引き戸１０を支持させる傾斜ステップ２５付き浴室下枠２０に適用したものである。該引き戸１０は、特に図１，２に示すように、第１引き戸１１、第２引き戸１２及び第３引き戸１３からなり、躯体開口部の上枠１、下枠２０及び縦枠２，２内に配置されている。第１引き戸１１、第２引き戸１２及び第３引き戸１３は、上枠１に付設されたレール（図外）に支持させることにより、開閉自在に吊り下げられる。また、第１引き戸１１、第２引き戸１２及び第３引き戸１３の下框の下部には、それぞれ下垂片１１ｂ，１２ｂ，１３ｂが形成されると共に、シール材１１ａ、シール材１２ａ、シール材１３ａが下垂状態で設けられる。
【０００６】
浴室出入り部の下枠２０は、特に図１に示すように、引き戸１０の下部枠を構成し、浴室床面（浴室パン）３と更衣室（図外）との間に敷設される。下枠２０の上面と更衣室の床面とは略同一高さで、下枠２０と浴室床３との高さの差は若干で、具体的には２０mm以下として形成される。下枠２０は、躯体上に配置される下枠基材２１と、下枠基材２１上に載置・係合される下枠載材２２と、該下枠載材２２の浴室側に連結される傾斜ステップ２５とからなる。
【０００７】
下枠基材２１の浴室側は浴室床面３上に載置されると共に浴室外側は躯体に支持される。また、この下枠基材２１には排水溝が形成されると共に、後述の下枠載材２２の載置部或いは係合部が形成される。下枠載材２２には、３つのシール材保持部２２ａ，２２ａ，２２ａが形成され、シール材２２ｂ，２２ｂ，２２ｂが付設される。
【０００８】
傾斜ステップ２５は、アルミ合金、硬質合成樹脂等を素材して形成され、側面視形状が略三角形の筒状で、浴室出入り部の幅に略等しい長さに形成されており、上面には傾斜面２５ｄが形成され、浴室側及び室外側の下面には、耐水性があって弾性素材からなる床当接部材２５ａ，２５ｂが設けられる。また、傾斜ステップ２５の室外側には下枠当接部２５ｃが形成される。
【０００９】
更に、傾斜ステップ２５の左右両端部近傍には、下枠２０への連結部材Ａが設けられる。即ち、傾斜ステップ２５の両端部近傍の傾斜面２５ｄには、図３に示すように、挿通孔２５ｅ，２５ｅが穿設され、頭大ボルト状の連結具２８が取り付けられる。そして、この連結具２８のネジ部２８ａには、図１，９に示すように、係合片２７が螺合されて取り付けられる。
【００１０】
係合片２７は、図４，５に示すように、平面視方形状で傾斜ステップ２５の内面上壁に当接する係合片本体２７ａと、その一側下方に折り曲げ状に形成されている鈎部２７ｃとからなる。係合片２７は金属弾性を有する鋼板が好適である。また、係合片本体２７ａには挿通ネジ穴２７ｂが穿設され、この挿通ネジ穴２７ｂには雌ねじ溝が形成され、前記連結具２８のネジ部２８ａが挿通・螺合される。鈎部２７ｃは、平面視Ｌ字の鈎型に形成され、下枠載材２２の支持部２２ｃに穿設されている水抜き穴（図外）に掛止する。この鈎部２７ｃは、傾斜ステップ２５に荷重がかかったときに傾斜ステップ２５がある程度下動が可能となるように構成されている。
【００１１】
傾斜ステップ２５の両端部には、その筒部開口を塞ぐようにキャップ２６，２６が取り付けられる。キャップ２６は、図６〜８に示すように、開口を塞ぐキャップ本体に対して、係合突片２６ａが形成されている。このキャップ２６の傾斜ステップ２５に対する位置関係は、図９に示されている。即ち、キャップ２６の係合突片２６ａが傾斜ステップ２５の両端部の空間部に弾性的に嵌挿される。
【００１２】
上記構成、即ち、浴室床面３と浴室出入り部の下枠２０上面との間に、若干の高低差がある浴室下枠構造において、浴室床面３と上記下枠２０間に傾斜ステップ２５を配置すると共に、該傾斜ステップ２５の側端部に連結具２８を介して係合片２７を付設し、傾斜ステップ２５の室外側を、下枠上に配置されている下枠載材２２に係合片２７によって連結させることで、連結具２８の操作部２８ｂを回転させて締め、下枠２０側に簡単に傾斜ステップ２５を取り付けることができる。逆に、傾斜ステップ２５を下枠２０から取り外すときには、操作部２８ｂを回転操作して緩め、且つ、下枠載材２２の支持部２２ｃから鈎部２７ｃを外す。したがって、傾斜ステップ２５は下枠２０の下枠載材２２から随時脱着ができるから、傾斜ステップ２５の取り替えや、浴室床面３上の清掃が容易となり、浴室の衛生管理が容易となる。
【００１３】
更に、実施例１では、鈎部２７ｃを下枠２０側の水抜き穴に掛止可能とすることで、既存の下枠装置を何ら加工することなく、傾斜ステップ２５を取り付けることができる。また、上記構成において、傾斜ステップ２５の室内側下部を、床当接部材２５ａを介して浴室床面に支持させると共に、傾斜ステップ２５の室外側下部を浴室床面３から離した状態で、傾斜ステップ２５の室外側側面を下枠載材２２に当接させることで、傾斜ステップ２５の室外側がある程度下動するから、出入りする人にとって、傾斜ステップ２５の踏み心地がよい。
【００１４】
（実施例１の別例）
実施例１では、鈎部２７ｃは下枠載材２２の支持部２２ｃに掛止されるが、必ずしも下枠載材２２に掛け止めする必要はなく、下枠２０に穿設されている水抜き穴等に直接掛止してもよい。また、水抜き穴ばかりでなく、下枠２０又は下枠載材２２に、新たに掛け止用の孔や凹部を形成してもよい。
【００１５】
また、連結具２８は、常に操作部８ｂとネジ部２８ａとが一体である必要はなく、分離可能で、操作時のみネジ部２８ａに装着するようにしてもよい。また、操作部８ｂも、ネジ部２８ａの構成によっては、単にネジ部２８ａを回転操作できる部材、例えば、杆状のものでもよい。更に、上記ネジ部２８ａに換えて、金属製の弾性係止片等でもよい。
【００１６】
【実施例２】
実施例２は、本発明の傾斜ステップ付き浴室下枠装置について、上述した実施例１に係る説明との相違部分のみを説明するものであり、図１０，１１に示すように、単一の引き戸１０の下枠２０に対して、傾斜ステップ２５を上方から着脱自在に付設することも可能である。この場合は、下枠２０の室内側に、頭大形状の連結ビス２９，２９を水平状に植設し、該連結ビス２９，２９に傾斜ステップ２５の室外側（下枠２０側）端縁に穿設したビス係合スリット２５ｇ，２５ｇを係合するように形成してもよい。この実施例２によれば、傾斜ステップ２５の着脱が簡略化し且つ容易で、浴室床３の清掃等に便利である。また、実施例２によれば、本発明に係る傾斜ステップ２５の装着を既存の浴室下枠装置にも適用できるばかりでなく、新規・既存の浴室下枠装置に拘わらず、傾斜ステップ２５の後付けが可能で、施工性の向上を図ることが可能となった。
【００１７】
（実施例２の別例）
実施例２においては、連結ビス２９，２９及びビス係合スリット２５ｇ，２５ｇの形状は、種々選択できる。例えば、各連結ビス２９頭部の形状を円筒形或いは角柱形とすることが可能であり、また、ビス係合スリット２５ｇ，２５ｇも、上部が狭いテーパ形状にすることができるし、また、奥広とすることも可能である。なお、特許請求の範囲の項には実施例との対応関係を明瞭にするために図面符合を付したが、本発明はこれに限るものではない。
【００１８】
【発明の効果】
本発明は、上記構成により、下記の効果を奏する。
請求項１記載の発明によれば、浴室床面と上記下枠間に傾斜ステップを配置すると共に、該傾斜ステップに設けられた連結部材を介して、傾斜ステップの室外側を下枠側に着脱可能に連結させることで、浴室下枠装置が新設・既設であることを問わず、傾斜ステップを下枠側に容易に且つ簡単な操作で着脱可能とし、傾斜ステップの交換、及び、清掃・排水を容易にする。上記効果に加えて、連結部材として、下枠の室内側に連結ビスを植設し、該連結ビスに傾斜ステップの室外側端縁に穿設したビス係合スリットを係合可能に形成することで、簡単な構成で傾斜ステップの装着を一層簡略化し、容易且つ確実にすることができる。
