本発明は、ビルやマンション等のテラス、窓等の障子の開口部装置に係り、大型化した窓障子や、風圧などを受けて開けにくいビル等の引違い式又は片引き式の障子を開ける際の開操作の初動を補助する開閉補助機構を有する開口部装置に関するものである。

【従来の技術】
【特許文献１】特願２００１−３５４２８７号
近年、多くのビルやマンション等のテラス、窓等の障子としてサッシが多く使用されている。特に建物自体の高層化や窓障子の大型化に伴い、風が吹いている時に障子を開ける際、吹き付ける風の風圧によって障子の中央部で撓みが生じ、窓障子の框枠に設けられた気密材が窓枠に押し付けられて密着して摩擦抵抗が大きくなって重くなり開け難く、特に、引違い式又は片引き式の障子では開け始めの際には強い力を要している。また例え、風圧を受けていなくても、引違い式の障子では施錠装置であるクレセント錠により施錠時に、召合い框に設けられた気密材が他方の障子の召合い框に押し付けられて密着状態となり、クレセント錠を開錠しても障子が開け難い場合もある。また、吹き付ける風圧により障子の撓み防止のために障子自体の構造を頑丈なものとすると障子自体の重量が増して重くなり障子の開け始めには強い力を要している。
【０００３】
ビルやマンション等での引違い式又は片引き式の窓障子を開ける際に、該窓障子の開け始めの際の初動の力を補助するためテコの原理を利用した開口部装置として、従来公知の手段として上記「特許文献１」に記載のように開口部の開閉補助機構を備えた開口部装置が提案されている。以下、この従来公知の開口部の開閉補助機構を開口部装置について図６〜８により説明する。
【０００４】
図６は開口部装置の室内側正面図で、符号３０は、ビルやマンション等で使用されている窓障子である。この窓障子３０は、上下の上枠３１ａ、下枠３１ｂ及び左右の縦枠３１ｃ、縦枠３１ｄとで方形に構成された枠体３１と、この枠体３１内に装着される二枚の障子３２、３２が、上枠３１ａ、下枠３１ｂに形成された溝及びレールの間に引違い式に開閉可能に装着されている。各障子３２、３２は、上下の上框３３ａ、下框３３ｂ及び左右の召合せ框３３ｃ、戸先框３３ｄとで方形に構成された框体３３と、該框体３３内に装着されたガラス３４とで構成されている。二枚の障子３２、３２の閉状態で互いに接するの召合せ框３３ｃ、３３ｃ間にはクレセント錠３５が設けられ、また、各障子３２、３２の戸先框３３ｄ、３３ｄ内には、障子を開ける際の初動を補助する把手部３７により操作される開閉補助機構３６、３６が収納されている。
【０００５】
図７は従来公知の開口部装置の一部横断面図、図８は従来公知の別の開口部装置の一部横断面図で、この障子３２の戸先框３３ｄの内部に収納された障子を開ける際の初動を軽減補助する開閉補助機構３６は、戸先框３３ｄの内部に設けられ縦枠３１ｃを押圧する反力で障子３２を開方向へ押し動かす作動部３８を有する本体部３９と、戸先框３３ｄの室内側に設けられた前記作動部３８を操作すると共に障子３２を開閉操作するための把手部３７とを有している。該本体部３９は角筒状に折曲げてなるケーシング４１を有し、このケーシング４１内にレバー状の作動部３８が回動自在に収容されている。この作動部３８の基部には、把手部３７に突設された断面四角形の駆動軸４２の先端部が嵌挿係合されており、作動部３８の先端にはローラ４４が軸支されている。ケーシング４１の縦枠がわ面には、作動部３８の先端部が出没可能な開口部が設けられており、ケーシング４１の上下の取付片部４６、４６はネジ４５、４５で戸先框３３ｄに取付けられている。なお、符号４０は、把手部３７を戸先框３３ｄの室内側に取付けるための台座部である。
【０００６】
障子３２を開ける場合には、障子３２の戸先框３３ｄの内部に収納された開閉補助機構３６の把手部３７を掴んで障子３２の開方向に力を加えると、把手部３７の回転力が駆動軸４２を介して作動部３８に伝達され、作動部３８が駆動軸４２を支点として回動し、作動部３８の先端のローラ４４がケーシング４１の開口部から縦枠３１ｃの内側面を押圧し、この押圧力による反力で障子３２を開ける際の初動を補助するものである。
【０００７】
また、前述した障子の戸先框の内部に障子の開操作時の初動を軽減補助する開閉補助機構を収納したタイプのものと別タイプのものとして、図８に示す開閉補助機構を障子の戸先框内に収納せずに、障子の戸先框の室内側の側面に取付た把手の台座部に開閉補助機構を内蔵したタイプのものがある。この戸先框の室内側の側面に台座部に組み込まれた開閉補助機構と把手とを面付けしたタイプのものでは、台座部に開閉補助機構が組み込まれているため台座部が大きくなり、更にこの台座部の室内側に把手が取付けられている。符号４７は、作動部３８の先端のローラ４４が当接する当り座金である。
【０００８】
【発明が解決しようとする課題】
しかしながら、上記した従来の障子の戸先框の内部に障子の開操作時の初動を軽減補助する開閉補助機構を収納したタイプのものでは、開閉補助機構が障子の戸先框の内部に収納されているので、室内側からの外観上の見栄えは良いが、障子の戸先框の内部に収納される開閉補助機構のスペースの関係で、専用の戸先框が必要となったり、また、製作現場や施工現場などで、中空体の戸先框の開放端から開閉補助機構を挿入して戸先框内の所定位置に取付けるための加工が非常に工数がかかり、コスト増となったり、施工現場での後付け作業は困難な作業となっている。
【０００９】
また、戸先框の室内側の側面に取付けた台座部に組み込まれた開閉補助機構と把手とを面付けしたタイプのものでは、台座部に開閉補助機構が組み込まれているため台座部が大きくなり、更にこの台座部の室内側に把手が取付けられるので、全体として室内側へ大きく張り出すため外観意匠性が悪く、また台座部の厚み（室内方向への高さ）も高くなってしまうので、把手全体の高さが高くなり、戸先框の室内側の側面から把手が大きく飛び出し、室内側のカーテンに干渉したり、室内側にロール網戸やプリーツ網戸が付いた場合に、網戸と把手とが干渉するので取付けできないと云う問題があった。また、戸先框に台座部に組み込まれた開閉補助機構と把手とを堅固に取付けるには、戸先框内に座金を収納して取付けなければならず、取付位置の調整が必要である。このように、従来の開閉補助機構を備えた開口部装置では、開口部装置が室内側に大きく張り出すことによる納まりや意匠性、および取付作業の施工性等の点で問題があった。
【００１０】
そこで、本発明は、上述した課題によりなされたもので、窓障子の開閉を容易とすると共に納まりや外観意匠性および取付作業の施工性の向上が図ることができ、障子の戸先框の室外側に設けた開閉補助機構を内蔵した開閉補助機構内蔵座金と障子の戸先框の室内側に設けた把手部とで障子の戸先框を挟持して取付けることにより、障子の室内側への把手部の張出し量を少なくすることができると共に、また、施工現場での取付けで、障子の戸先框の室外側に設けた開閉補助機構内蔵座金に把手取付用裏板の機能を持たせることができるので、従来の障子の戸先框への開口部装置の取付けの際に、障子の戸先框内に取付用の裏板の挿入作業を省くことができると共に、また、室外側からの開閉時にも操作性の向上を図ることができるようにした障子の開口部装置を提供することを目的とするものである。
【００１１】
【課題を解決するための手段】
上記の目的を達成するため、本発明の請求項１に記載の発明は、建物の開口に設けられる上下の枠及び左右の縦枠とで方形状に形成された枠体と、該枠体内に引違い式又は片引き式に開閉自在に設けられ上下の框と左右の戸先框と召合い框とで方形状に形成された障子とからなる開口部装置において、該障子の戸先框の室外側には障子の開操作を補助する開閉補助機構を内蔵した開閉補助機構内蔵座金を設けると共に、該障子の戸先框の室内側には障子を開閉操作するための把手部を設け、該開閉補助機構は、縦枠を押圧する反力で障子を開方向へ押し動かす作動部を有する本体部を有し、該本体部は、前記把手部の開操作に連動して操作されるものである。
【００１２】
【発明の実施の形態】
以下、本発明の開口部装置の実施の態様を図１〜図５によって説明する。図１は、本発明の開口部装置の拡大横断面部分図、図２は、本発明の開口部装置を障子の戸先框への取付け図、図３は、本発明の開口部装置の障子の戸先框への取付け横断面図、図４は、本発明の開口部装置の操作説明側面図、図５は、本発明の開口部装置の回動アームの作動説明図である。
【００１３】
本発明の開口部装置も、図６により前述した従来の開口部装置と同様、ビルやマンション等で使用されている窓等の障子に使用されるもので、窓障子は建物の開口に、上下の上枠、下枠及び左右の縦枠とで方形に構成された枠体と、この枠体内に装着される二枚の障子が、上枠、下枠に形成された溝及びレールの間に引違い式に開閉可能に装着されている。各障子は、上下の上框、下框及び左右の召合せ框、戸先框とで方形に構成された框体と、該框体内に装着されたガラスとで構成され、障子の戸先框には、障子の開操作の際に初動を補助する把手部により操作される開閉補助機構が設けられている。
【００１４】
図１は本発明の開口部装置を示しており、符号１は、方形に構成された開口部の枠体の縦枠で、符号２は、方形に構成された開口部の枠体内に装着される障子８の戸先框である。この障子８の戸先框２の室内側には、取付座金３を介して把手部４が取付けられ、障子８の召合せ框９には、相手側の障子８の召合せ框９との間に施錠するクレセント錠１０が取付けられている。また、戸先框２の室外側には、障子の開操作を補助する開閉補助機構を内蔵した開閉補助機構内蔵座金５が取付けられ、障子８の戸先框２は、室内側に取付座金３を介在して取付けられる把手部４と、室外側に取付けられる開閉補助機構を内蔵した開閉補助機構内蔵座金５とによって挟持して取付けられている。符号６は開閉補助機構内蔵座金５に内蔵された開閉補助機構の回動アーム１４の先端にローラ軸１６で軸支されたローラである。
【００１５】
障子８の戸先框２の室内側には取付座金３、把手部４が、また、室外側には開閉補助機構内蔵座金５とが取付ネジ１３、１３で取付けられている。符号１２は、把手部４の基部に突設された回動軸で、その断面形状は四角形で、開閉補助機構内蔵座金５に内蔵された開閉補助機構の回動アーム１４の基部の軸孔と嵌装係合し、把手部４の回動力が回動軸１２を介して回動アーム１４に伝達される。回動アーム１４を図４に示すようにイ方向の回動により回動アーム１４先端にローラ軸１６で軸支されたローラ６は、開閉補助機構内蔵座金５の縦枠側に形成されている開口部（図示されていない）から突出して、ネジ１５で縦枠１に取付けられた当り座金７に当接する。
【００１６】
次に、障子８の戸先框２の室外側に取付けられた開閉補助機構内蔵座金５に内蔵された開閉補助機構について説明する。開閉補助機構内蔵座金５は剛性を有する金属板を断面長方形の角筒状に折曲げて形成され、その前面部には開口部が形成されている。また、開閉補助機構内蔵座金５の両側部には、把手部４の基部から突設した回動軸１２を支承する円孔が形成されており、この開閉補助機構内蔵座金５の両側部の円孔と円孔との間に、基部に四角形の孔が設けられたレバー状の回動アーム１４が位置して収納されている。これら開閉補助機構内蔵座金５の一側部の円孔、回動アーム１４基部の四角形の軸孔、及び開閉補助機構内蔵座金５の他側部の円孔とに亘って把手部４の回動軸１２が嵌装係合されている。この時、基部の四角形の孔と把手部４の回動軸１２と回動アーム１４の基部とは互いに把手部４の回動軸１２は断面形状四角形であり、また、回動アーム１４の基部には該回動軸１２が嵌装係合する四角形の軸孔が設けられているので、把手部４の回動力が回動軸１２を介して回動アーム１４に伝達される。
【００１７】
障子８の閉状態で把手部４を図４に示す矢印のイ方向に回動すると、把手部４からの回動力は、把手部４に突設された回動軸１２を介して回動アーム１４が回動し、回動アーム１４の先端に軸支されたローラ６は、開閉補助機構内蔵座金５の前面部に形成された開口部から突出する。そして、この開口部から突出した該ローラ６は、縦枠１の内側面に設けられた当り座金７と当接し、障子８は、回動アーム１４の先端に軸支されたローラ６が該当り座金７を押圧する反力で開方向へ押し動かす。
【００１８】
符号１７は、開閉補助機構内蔵座金５の前面部開口部から突出した回動アーム１４を開閉補助機構内蔵座金５内へ復帰没入させるための付勢手段である復帰バネで、該復帰バネ１７の一端は開閉補助機構内蔵座金５の適宜個所に固定されていると共に、復帰バネ１７の他端は回動軸１２の回りを巻装して回動アーム１４の側部に設けたバネ軸１８に固定されている。把手部４に障子に開操作の力が加えられなくなると、先端にローラ６を軸支した回動アーム１４は復帰バネ１７の力により開閉補助機構内蔵座金５内に復帰する。また、回動アーム１４の基部には開閉補助機構内蔵座金５の後面壁と当接して回動アーム１４の突出方向への回動を所定の範囲で規制するためのストッパー１９が設けられており、回動アーム１４の突出方向への回動は、ストッパー１９が開閉補助機構内蔵座金５の後面壁と当接することで規制しており、回動アーム１４の復帰バネ１７による没入時には、回動アーム１４が開閉補助機構内蔵座金５の後面壁に当接することで規制されている。
【００１９】
次に、上述した構成を有する本発明の開口部装置の作用について説明する。障子８の戸先框２の室内側と室外側とにそれぞれ把手部４と開閉補助機構を内蔵した開閉補助機構内蔵座金５とで挟持して取付けられた本発明の開口部装置を備えた障子８が、建物の開口に方形に構成された枠体内に引違い式に開閉可能に装着された実施の態様において、全閉状態にある障子８の召合せ框９のクレセント錠１０を開錠して、室内側に設けられた把手部４を図４に示す矢印イの方向に回動すると、把手部４からの回動力は、把手部４に突設された回動軸１２を介して回動アーム１４を復帰バネ１７に抗しながら回動する。
【００２０】
このとき、回動する回動アーム１４の基部にはストッパー１９が設けられているので、該ストッパー１９が開閉補助機構内蔵座金５の後面壁と当接するまで回動アーム１４は回動し、回動アーム１４の先端に軸支されたローラ６は、開閉補助機構内蔵座金５の前面部に形成された開口部から突出する。この開口部から突出したローラ６は、縦枠１の内側面に設けられた当り座金７と当接し、回動アーム１４の先端に軸支されたローラ６が該当り座金７を押圧する反力で障子８を開方向へ押し動かし始める。このローラ６が縦枠１の内側面を押す反力で障子８を開方向へ押し動かす力が、人による障子８の把手部４で障子８を開けようとする力にアシストされるので、例え、障子８に吹き付ける風の風圧によって障子８の戸先框２に設けられた気密材が窓の縦枠１に密着していたとしても、開操作の初動時において、開閉補助機構を内蔵した開閉補助機構内蔵座金５の回動アーム１４の先端に軸支されたローラ６によるアシスト力が障子８に作用するので、容易に障子８を開けることができる。
【００２１】
このように、本発明の開口部装置では、障子８の戸先框２の室内側と室外側とにそれぞれ把手部４と開閉補助機構を内蔵した開閉補助機構内蔵座金５とで狭持して取付けているので、障子の開操作の初動時においては、障子８の戸先框２の室内側に取付けられた把手部４の操作により、室外側に取付けられた開閉補助機構を内蔵した開閉補助機構内蔵座金５の開操作補助操作により開操作時の初動の開操作を軽減しすると共に、従来公知の障子の戸先框の室内側の側面に取付けた台座部に組み込まれた開閉補助機構と把手部とを面付けしたタイプのように、障子の戸先框の室内側の側面から開閉補助機構が組込んだ台座部や把手部が、室内側へ大きく張出すことは無いので納まりや意匠的にも良く、また、室内側への張出し部は把手部だけであるので、室内側に取付ける紙障子、カーテン、ロール網戸やプリーツ網戸と干渉することなく取付けることができる。このため従来のように、障子と紙障子、カーテン、ロール網戸、プリーツ網戸との間隔を大きく採る必要がなく、これらを設けるための室内側への突出部を造る必要もなく、また反対に、必要以上に大きな出窓を取付ける必要もない。
【００２２】
また、従来公知の障子の戸先框の内部に開閉補助機構を収納したタイプのように、内部に開閉補助機構を収納するために専用の戸先框を必要とせず、また、製作現場や施工現場などで中空体の戸先框内に開閉補助機構を挿入することもなく、戸先框への取付け加工工数を軽減することができる。また、ベランダ等では、障子の戸先框の室外側に取付けた開閉補助機構内蔵座金を、ベランダ側から障子を開けるための把手部の代わりとして利用することができる。なお、本発明の開口部装置において、開閉補助機構内蔵座金内で回動する回動アームの先端に軸支したローラで、開口部の縦枠の側面に設けた当り座金を設けた場合について説明したが、ローラが直接縦枠の側面を押すようにしてもよい。
【００２３】
【発明の効果】
以上説明したように、本発明の開口部装置は、建物の開口の方形状の枠体内に引違い式又は片引き式に開閉自在に設けられた障子の戸先框の室外側に設けた開閉補助機構を内蔵した開閉補助機構内蔵座金と障子の戸先框の室内側に設けた把手部とで障子の戸先框を挟持して取付けているので、開閉補助機構により窓障子の開閉を容易とすると共に、障子の室内側への把手部の張出し量を少なくすることができるので、納まりや外観意匠性の向上を図ることができる、また、室内側の把手部と室外側の開閉補助機構を内蔵した開閉補助機構内蔵座金とで障子の戸先框を挟持して取付けるだけなので、取付作業の施工の向上を図ることができる、と云う効果を奏する。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a device for opening a shoji such as a terrace of a building or an apartment, or a shoji such as a window, and opens a sliding window or a sliding-type shoji such as a large-sized window shoji or a building which is difficult to open due to wind pressure or the like. The present invention relates to an opening device having an opening and closing assist mechanism for assisting an initial movement of an opening operation at the time.
[0002]
[Prior art]
[Patent Document 1] Japanese Patent Application No. 2001-354287 In recent years, sashes are often used as shojis for terraces, windows and the like of many buildings and condominiums. In particular, with the height of the building itself and the size of the window shoji, when opening the shoji when the wind is blowing, the wind pressure of the blowing causes the center of the shoji to bend, and the airtightness provided in the frame of the window shoji The material is pressed against the window frame and comes into close contact with it, increasing the frictional resistance and becoming heavy and difficult to open. In particular, a sliding or single-pull sliding door requires a strong force at the beginning of opening. Even if it is not subjected to wind pressure, in the case of a sliding type sliding door, at the time of locking by the crescent lock which is a locking device, the airtight material provided on the mating frame is pressed against the mating frame of the other sliding door and is in a close contact state. In some cases, even if the crescent tablet is unlocked, the shoji cannot be easily opened. Further, if the structure of the shoji itself is made robust to prevent the shoji from bending due to the blowing wind pressure, the weight of the shoji itself increases and becomes heavy, and a strong force is required to start opening the shoji.
[0003]
Conventionally known as an opening device utilizing the principle of leverage to assist in the initial movement force when opening a sliding or single sliding window shoji in a building or an apartment, etc. As means for this, there has been proposed an opening device provided with an opening / closing assisting mechanism as described in Patent Document 1. Hereinafter, this conventionally known opening / closing assisting mechanism for an opening will be described with reference to FIGS.
[0004]
FIG. 6 is a front view of the inside of the opening device, and reference numeral 30 denotes a window shoji used in a building or an apartment. The window shoji 30 has a rectangular frame 31 composed of an upper frame 31a, a lower frame 31b, left and right vertical frames 31c, and a vertical frame 31d, and two shojis mounted in the frame 31. 32, 32 are mounted between the grooves and the rails formed in the upper frame 31a and the lower frame 31b so as to be openable and closable. Each of the sliding doors 32, 32 has a rectangular frame 33 formed by upper and lower upper frames 33a, lower frames 33b, left and right assembling frames 33c, and door frames 33d, and glass mounted in the frames 33. 34. A crescent lock 35 is provided between the mating frames 33c, 33c which are in contact with each other in the closed state of the two sliding doors 32, 32, and the sliding doors 33d, 33d of the sliding doors 32, 32 are provided with a sliding door. Opening and closing assist mechanisms 36 and 36 operated by a handle 37 for assisting initial movement when opening are housed.
[0005]
FIG. 7 is a partial cross-sectional view of a conventionally-known opening device, and FIG. 8 is a partial cross-sectional view of another conventionally-known opening device. The opening and closing assist mechanism 36 for reducing the initial movement when the door is opened is provided with a main body 39 having an operating portion 38 provided inside the door frame 33d and for pushing the shoji 32 in the opening direction by a reaction force for pressing the vertical frame 31c. And a handle 37 for operating the operating portion 38 provided on the indoor side of the door frame 33d and for opening and closing the shoji 32. The main body 39 has a casing 41 which is bent into a rectangular cylindrical shape, and a lever-shaped operating portion 38 is rotatably accommodated in the casing 41. A distal end of a drive shaft 42 having a rectangular cross section protruding from the handle 37 is fitted and engaged with a base of the operating portion 38, and a roller 44 is supported at the distal end of the operating portion 38. . The vertical frame of the casing 41 is provided with an opening through which the distal end of the operating portion 38 can protrude and retract, and the upper and lower mounting pieces 46, 46 of the casing 41 are screwed with the door frame 33d by screws 45, 45. Mounted on Reference numeral 40 denotes a pedestal for attaching the handle 37 to the indoor side of the door frame 33d.
[0006]
When the shoji 32 is opened, when the user grips the handle 37 of the opening and closing auxiliary mechanism 36 housed inside the door frame 33d of the shoji 32 and applies a force in the opening direction of the shoji 32, the rotational force of the handle 37 is reduced. The driving force is transmitted to the operating portion 38 via the driving shaft 42, and the operating portion 38 rotates about the driving shaft 42, and the roller 44 at the tip of the operating portion 38 presses the inner surface of the vertical frame 31 c from the opening of the casing 41. Then, the initial force at the time of opening the shoji 32 by the reaction force due to the pressing force is assisted.
[0007]
Further, as a different type from the above-described type in which the opening and closing assist mechanism for reducing the initial movement at the time of opening the shoji is stored inside the door frame of the shoji, the opening and closing assist mechanism shown in FIG. There is a type in which an opening / closing auxiliary mechanism is built in a pedestal portion of a handle attached to the indoor side surface of a door frame of a sliding door without being stored in the front frame. In the type in which the opening / closing auxiliary mechanism incorporated in the pedestal portion and the handle are imposed on the indoor side surface of this door frame, the pedestal portion becomes large because the opening / closing auxiliary mechanism is incorporated in the pedestal portion. A handle is attached to the indoor side of the pedestal portion. Reference numeral 47 denotes a contact washer against which the roller 44 at the tip of the operating section 38 comes into contact.
[0008]
[Problems to be solved by the invention]
However, in the type in which the opening / closing auxiliary mechanism for reducing the initial movement at the time of the opening operation of the shoji is stored inside the above-mentioned conventional sliding door frame, the opening / closing auxiliary mechanism is stored inside the door frame of the sliding door. The exterior appearance from the indoor side is good, but due to the space of the opening and closing auxiliary mechanism stored inside the door frame of the shoji, a special door frame is required, and At the site or construction site, the process of inserting the opening and closing auxiliary mechanism from the open end of the hollow door frame and mounting it at a predetermined position in the door frame takes a lot of man-hours, increasing the cost and construction Post-installation work on site is a difficult task.
[0009]
In the type in which the handle and the opening / closing auxiliary mechanism incorporated in the pedestal attached to the indoor side of the door frame are imposed, the pedestal is large because the opening / closing auxiliary mechanism is incorporated in the pedestal. Further, since the handle is attached to the interior side of the pedestal part, the overall design is greatly extended to the interior side, so that the appearance design is poor, and the thickness of the pedestal part (height in the interior direction) is also increased. If the overall height of the handle rises and the handle protrudes greatly from the indoor side of the door frame and interferes with the curtain on the indoor side, or if there is a roll screen or pleated screen on the indoor side, the screen and handle There is a problem that it cannot be mounted because of interference. Further, in order to firmly attach the handle and the opening / closing auxiliary mechanism incorporated in the base portion to the door frame, it is necessary to store and mount the washer in the door frame, and it is necessary to adjust the mounting position. As described above, in the opening device having the conventional opening / closing assist mechanism, there are problems in terms of fit and design due to the opening device protruding largely toward the indoor side, workability in mounting work, and the like.
[0010]
Therefore, the present invention has been made in view of the above-mentioned problem, and it is possible to easily open and close a window shoji, and to improve the fit and appearance design and the workability of the mounting work, and to provide a door frame for a shoji door. The door frame of the sliding door is sandwiched between the washer with a built-in opening and closing auxiliary mechanism provided on the outside and the handle provided on the indoor side of the door frame of the sliding door. The overhang of the handle can be reduced, and the washer with a built-in opening / closing auxiliary mechanism provided outside the door frame of the shoji door at the construction site has the function of a back plate for attaching the handle. Therefore, when mounting the opening device to the conventional door frame of the shoji screen, the work of inserting the back plate for mounting into the door frame of the shoji screen can be omitted, and also from the outdoor side. Improved operability when opening and closing It is an object to provide an opening device of the shoji.
[0011]
[Means for Solving the Problems]
In order to achieve the above object, the invention according to claim 1 of the present invention provides a frame formed in a square shape by upper and lower frames and left and right vertical frames provided in an opening of a building, and In an opening device consisting of a sliding door formed in a square shape with upper and lower frames, left and right door frames and a siding frame, which are provided to be openable and closable in a pulling type or a single pulling type, An opening / closing auxiliary mechanism built-in washer having a built-in opening / closing auxiliary mechanism for assisting the opening operation of the shoji is provided on the outside, and a handle portion for opening / closing the shoji is provided on the indoor side of the door frame of the shoji.
