Description

【０００１】
【発明の属する技術分野】
本発明は、主として学校、病院などに用いられるスライディングサッシに関する。
【０００２】
【従来の技術】
スライディングサッシとしては、サッシ枠に内障子と外障子を面内方向に移動自在にそれぞれ装着した引き違いサッシ、サッシ枠の室外側部に障子を面内方向に移動自在に装着した外動片引きサッシ、サッシ枠の室内側部に障子を面内方向に移動自在に装着した内動片引きサッシなどが知られている。
【０００３】
学校、病院などに用いられるスライディングサッシとしては、障子の開放ストロークを制限して障子を全開できないようにすることで、障子を開放した時のサッシの開口幅を全開幅よりも小さくし、サッシ開口部から人が誤って落下しないようにしたものが知られている。
例えば、障子の開放ストロークを制限するスライディングサッシが実開平４−１１９０８８号公報（実用新案登録第２５４２８２１号公報）に開示されている。
このスライディングサッシは、サッシ枠の下枠に固定部材を取付け、サッシ枠の室外側部に装着した障子の下框に受けブロックを取付け、この受けブロックがストッパに当たることで障子の開放ストロークを制限するものである。
【０００４】
また、火災等の非常時に室外から開放して非常進入口として利用できるようにスライディングが提案されている。
例えば、特開平８−１６５８２７号公報には、外ハンドルで障子の解錠をできるようにし、非常時には室外から外ハンドルを操作して障子を解錠して開放できるようにしたスライディングサッシが開示されている。
【０００５】
【発明が解決しようとする課題】
前述した固定部材と受けブロックを取付けると共に、前述した外ハンドルを設けることで、障子の開放ストロークを制限できると共に、室外から開放できるようにしたスライディングサッシとすることが可能である。
しかしながら、前述のようにしたスライディングサッシは、室外から外ハンドルを操作して障子を解錠して障子を開放した時に固定部材と受けブロックのために障子の開放ストロークが制限され、障子を全開できない。
このために、室外から障子を開放した時のサッシの開口幅が小さく、人が出入りしづらいから非常進入口として好ましくない。
【０００６】
本発明は、前述の課題に鑑みなされたものであり、その目的は室内から障子を開放する時には開放ストロークを制限し、室外から障子を開放する時には開放ストロークを制限せずに全開できるようにしたスライディングサッシを提供することを目的とする。
【０００７】
【課題を解決するための手段】
第１の発明は、サッシ枠に障子を面内方向に開閉移動自在に装着され、
この障子を閉じ位置で施錠・解錠すると共に、室内から施錠・解錠でき、かつ室外から解錠できる錠装置と、
前記サッシ枠と障子とに亘って設けられ室内又は室外から障子の開放ストロークを全開より小さくする制限状態と全開とする非制限状態に操作される障子の開放ストロークを制限する開放制限装置を備えていることを特徴とするスライディングサッシである。
【０００８】
第２の発明は、第１の発明においてサッシ枠に取付けたストッパ部と、障子に設けた受け部と、この受け部を障子を開放した時にストッパ部と当接しない第１位置と、当接して開放ストロークを制限する第２位置に移動する操作部材で開放制限装置とし、
前記操作部材は障子の室内側部に取付けられていると共に、障子の引寄せ、引寄せ解除の機能を有し、受け部が第１位置の時には障子を引寄せ、第２位置の時には引寄せ解除する構成としたスライディングサッシである。
【０００９】
第３の発明は、第１の発明においてサッシ枠に取付けたストッパ部と、障子に設けた受け部と、この受け部を障子を開放した時にストッパ部と当接しない第１位置と、当接して開放ストロークを制限する第２位置に移動する操作部材で開放制限装置とし、
前記操作部材は障子の室外側部に取付けられているスライディングサッシである。
【００１０】
第４の発明は、第１又は第２又は第３の発明において錠装置は、室内側操作部材と室外側操作部材で施錠・解錠される構成であるスライディングサッシである。
【００１１】
第５の発明は、サッシ枠に障子を面内方向に開閉移動自在に装着され、
室内側操作部材によって障子を閉じ位置で施錠・解錠する錠装置と、
室外側操作部材によって障子の開放ストロークを制限する制限状態と制限しない非制限状態に操作される開放制限装置を備え、
前記室内側操作部材と室外側操作部材が、室内側操作部材を操作して錠装置を施錠・解除する時には室外側操作部材が動かずに開放制限装置が制限状態に保持され、錠装置が施錠状態で室外側操作部材を操作して開放制限装置を非制限状態とすると錠装置が解錠するように連結されていることを特徴とするスライディングサッシである。
【００１２】
【作　用】
第１の発明によれば、開放制限装置を制限状態として室内から錠装置を解錠して障子を開放することで、障子の開放ストロークを制限できる。
また、開放制限装置を非制限状態として室外から錠装置を解錠して障子を開放することで、障子を全開できる。
よって、室内から障子を開放する時には開放ストロークが制限されてサッシ開口幅が小さく、学校や病院などに用いるスライディングサッシとして好ましい。
しかも、室外から障子を全開できるから非常進入口として有効利用できる。
【００１３】
第２の発明によれば、障子を施錠した時には操作部材を操作して障子を引寄せるので、受け部が第１位置に移動するから、室外から錠装置を解錠することで障子を全開できる。
室内から障子を開放する時には錠装置を解錠すると共に、操作部材を操作して引寄せ解除するので、受け部が第２位置に移動するから、室内から障子を開放する時には開放ストロークを制限できる。
しかも、引寄せ、引寄せ解除と連動して受け部が第１位置、第２位置に移動するから、誤操作することがない。
【００１４】
第３の発明によれば、非常時など室外から障子を開放する時には操作部材を操作して受け部を第１位置とすることで、障子を全開できる。
通常時には受け部を第２位置に保持することで、室内から障子を開放する時に開放ストロークを制限できる。
【００１５】
第４の発明によれば、錠装置を室内側操作部材及び室外側操作部材で施錠、解錠できる。
【００１６】
第５の発明によれば、錠装置が施錠状態で室外側操作部材を操作することで開放制限装置を非制限状態とすると錠装置が解錠され、室外から障子を全開できる。
開放制限装置が制限状態で、室内側操作部材を操作して錠装置を施錠・解錠する際には開放制限装置は制限状態に保持され、室内から障子を開放する時には開放ストロークを制限できる。
【００１７】
【発明の実施の形態】
本発明の第１の実施の形態を図１に基づいて説明する。
サッシ枠１には障子２が面内方向に開閉移動自在に装着されてスライディングサッシを構成している。
前記障子２を閉じ位置で施錠・解錠すると共に、室内から施錠・解錠でき、かつ室外から解錠できる錠装置３を備えている。
例えば、障子２の室内側部に取付けた室内側操作部材４と室外側部に取付けた室外側操作部５を備え、室内側操作部材４を操作することで施錠・解錠でき、室外側操作部材５を操作することで解錠できる。なお、施錠できるようにしても良い。
前記サッシ枠１と障子２とに亘って障子２の開放ストロークを制限する開放制限装置６が設けてある。
この開放制限装置６は室内又は室外から障子２の開放ストロークを全開より小さくする制限状態と全開とする非制限状態に操作できる。
例えば、サッシ枠１に設けたストッパ部７と、障子２に設けた受け部８、操作部材９を備え、この受け部８は障子２を開放した時にストッパ部７と当接しない第１位置と、当接して開放ストロークを制限する第２位置とに亘って移動自在で、操作部材９を室内から操作することで受け部８が第１位置と第２位置に移動する。
【００１８】
図１に示す実施の形態では、受け部８は点線で示す上方位置（第１位置）と二点鎖線で示す下方位置（第２位置）に上下移動し、操作部材（ハンドル）９で回転される軸１０にグレモン機構などの回転を往復動に変換する変換機構１１を設け、この変換機構１１で上下動される杆体１２に受け部８が連結してある。
受け部８が上方位置であるとストッパ部７と高さ方向の位置がずれて障子２を開放しても受け部８がストッパ部７に当接しない（つまり、非制限状態である）。
受け部８が下方位置であるとストッパ部７と同一高さとなり、障子２を開放するとストッパ部７に当接する（つまり、制限状態である）。
なお、受け部８が上方位置の時にストッパ部７と同一高さで、下方位置の時にストッパ部７と高さ方向の位置が異なるようにしても良い。
【００１９】
このようであるから、操作部材９を操作して受け部８を上方位置（第１位置）とすることで開放制限装置６が非制限状態となり、障子２を閉じ位置から開きエンド位置まで移動できる。つまり、障子２を全開できる。
また、操作部材９を操作して受け部８を下方位置（第２位置）とすれば制限状態となり、障子２が開きエンド位置まで移動する手前で図１に一点鎖線で示すように受け部８がストッパ部７に当接するので、その開放ストロークを制限する。よってサッシの開口幅Ｈが小さくなる。
【００２０】
このようであるから、錠装置３で障子２を施錠している状態では操作部材９を操作して受け部８を第１位置に保持する。
この状態で室外から室外側操作部材５で錠装置３を解錠すれば、障子３を室外から全開でき、非常進入口として利用できる。
室内から錠装置３を解錠して開放する時には操作部材９を操作して受け部８を第２位置とするようにする。これによって、室内から障子２を開放する時には受け部８がストッパ部７に当接し、障子２の開放ストロークが制限され、サッシ開口幅が小さいので、学校、病院などに用いるスライディングサッシとして好ましい。
【００２１】
前述のように、錠装置３で障子２を施錠している状態で受け部８を第１位置に保持し、室内から錠装置３を解錠して開放する時に受け部８を第２位置とするには、操作部材９が受け部８を移動すると共に、その操作部材９によって障子２を引寄せ、引寄せ解除するようにすることが考えられる。
例えば、操作部材９を操作して障子２を引寄せすると受け部８が第１位置に移動し、操作部材９を操作して障子２の引寄せを解除すると受け部８が第２位置に移動するように構成する。
この場合には、受け部８が上方位置で第１位置、下方位置で第２位置とすることが好ましい。
【００２２】
このようにすれば、室内から施錠する時には操作部材９を操作して障子２を引寄せするので、受け部８が第１位置に保持される。
室内から障子２を開放する時には解錠すると共に、操作部材９を操作して障子２の引寄せを解除するので、受け部８が第２位置に移動し、室内から障子２を開放する時の開放ストロークを制限することができる。
【００２３】
次に、各部材の具体例を図１、図２、図３に基づき説明する。
サッシ枠１は上枠２０と下枠２１と左右の縦枠２２を方形枠状に連結してあると共に、上枠２０の室内寄り部と下枠２１の室内寄り部に亘って縦骨２３が連結され、この縦骨２３と一方の縦枠２２と上枠２０、下枠２１とに亘ってパネル材２４が装着されてサッシ枠１の面内方向一側室内寄り部を固定障子２５としてある。
前記障子２はサッシ枠１の室外寄り部に面内方向に移動自在に装着され、この実施の形態では外動片引きサッシを形成している。
なお、サッシ枠１の面内方向一側室外寄り部に障子を固定して内動片引きサッシとしても良い。
【００２４】
前記障子２は上框３０と下框３１と召合せ框３２と戸当り框３３を方形状に連結し、その内部にパネル材３４が装着してある。
前記錠装置３は召合せ框３２の室内側部に取付けた前記室内側操作部材（例えばハンドル）４と召合せ框３２の室外側部に取付けた前記室外側操作部材（例えばハンドル）５と、縦骨２３の室内側部に取付けた錠受け３５と、この錠受け３５に係脱する錠３６を備え、前記室内側操作部材４、室外側操作部材５によって錠３６を錠受け３５に係止して施錠したり、離脱して解錠できるようにしてある。
例えば、室内側操作部材４と室外側操作部材５を同一の軸３７に設けて連動し、室内側操作部材４にクレセントを設けて錠３６とし、縦骨２３にクレセント受けを設けて錠受け３５とする。
【００２５】
前記ストッパ部７は下枠２１における縦骨２３と他方の縦枠２２との間の位置に取付けてある。このストッパ部７はゴムなどの衝撃力を吸収緩和できる材質とすることが好ましく、ビス等で固着される。
前記受け部８は障子２の戸当り框３３の下部寄りに上下動自在に設けてある。
例えば、受け部８が下方位置であるとストッパ部７と同一高さとなって前述の第２位置で、受け部８が上方位置であるとストッパ部７よりも上方で前述の第１位置である。
前記戸当り框３３の室内側部に前述の操作部材９、例えばハンドルが取付けてある。
【００２６】
この実施の形態では、下枠２１は室内側部２１ａが室外側部２１ｂよりも高い階段形状で、その室内側部２１ａと室外側部２１ｂを連続する縦向部２１ｃにストッパ部７が固着してある。
障子２の戸当り框３３の中空部３３ａに前記変換機構１１、杆体１２が設けられ、その中空部３３ａを形成する室内側縦板３３ｂの下部寄りに上下方向の長孔３３ｃを形成し、この長孔３３ｃから受け部８が上下動自在となるように突出している。
【００２７】
次に、前記操作部材９の操作によって障子２を引寄せ、引寄せ解除する実施の形態を説明する。
前述の変換機構１１によって上下反対方向に移動する上下の杆体１２を設け、この各杆体１２に図４に示すように上摺動片４０、下摺動片４１をそれぞれ取付ける。
上摺動片４０は上方に移動することで上枠２０の一部、例えば上ガイドレール２０ａに圧接して障子２（戸当り框３３）を室内側に引寄せる。
下摺動片４１は下方に移動することで下枠２１の一部、例えば下ガイドレール２１ｄに圧接して障子２（戸当り框３３）を室内側に引寄せる。
前記下摺動片４１に受け部８を設ける。例えば、ビス４２で固着する。なお、下摺動片４１と受け部８を一体としても良い。
この場合には前述のように、受け部８が下方位置の時にストッパ部７よりも下方で、前述の第１位置となり、受け部８が上方位置の時にストッパ部７と同一高さで前述の第２位置となる。
【００２８】
このようであるから、障子２を閉じ位置として操作部材９を一方向に操作して上の杆体１２を上方、下の杆体１２を下方に移動すると上摺動片４０が上ガイドレール２０ａに圧接し、下摺動片４１が下ガイドレール２１ｄに圧接して障子２（戸当り框３３）を室内側に引寄せる。
これと同時に受け部８が下方位置に移動する。
障子２を開放する時には操作部材９を他方向に操作して上の杆体１２を下方、下の杆体１２を上方に移動して上摺動片４０、下摺動片４１を上ガイドレール２０ａ、下ガイドレール２１ｄから離隔して引寄せを解除する。
これと同時に受け部８が上方位置に移動してストッパ部７と同一高さとなるので、障子２の開放ストロークを制限できる。
なお、このようにした場合には室内側操作部材４の操作によっても障子２（召合せ框３２）を室内側に引寄せするようにすることが好ましい
例えば、召合せ框３２に前述と同様に上摺動片と下摺動片を上下動自在に取付ける。
【００２９】
次に、前記開放制限装置６を室外から制限状態と非制限状態とに操作できる実施の形態を説明する。
図５に示すように、召合せ框３２の中空部３２ａに変換機構１１と杆体１２を設け、その杆体１２に受け部８を取付ける。
召合せ框３２の室外側部、例えば中空部３２ａを形成する室外側縦板３２ｂに操作部材９を取付け、この操作部材９を室外から操作することで受け部８を第１位置と第２位置、例えば上方位置と下方位置に移動できるようにする。
障子２の下枠２１における縦骨２３と一方の縦枠２２との間にストッパ部７を取付ける。
【００３０】
このようにした場合には、室外から操作部材９を操作して受け部８を第１位置とすると共に、室外側操作部材５を操作して錠装置３を解錠することで、障子２を全開する。
通常時には操作部材９を受け部８が第２位置となる位置に保持し、室内から障子２を開放する時に受け部８がストッパ部７に当接して開放ストロークを制限する。
【００３１】
また、図６に示すように、室外側操作部材５によって開放制限装置６を制限状態と非制限状態に操作できると共に、錠装置３を解錠でき、室内側操作部材４で施錠・解錠する時には開放制限装置６を制限状態に保持するように構成する。
例えば、室内側操作部材４に連結された第１軸５０と室外側操作部材５に連結された第２軸５１を所定角度範囲で一体となって回転し、それ以外の角度範囲では相互に自由に回転するように連結し、その第２軸５１に変換機構１１を設けて受け部８を第１位置と第２位置に移動する。
【００３２】
例えば、図７に示すように第１軸５０は突部５２を有し、第２軸５１は切欠部５３を有する。
前記突部５２が切欠部５３に突出するように第１軸５０と第２軸５１が連結され、第１軸５０は第２軸５１に対して切欠部５３の範囲内では自由に回転する。
この実施の形態では、室内側操作部材４を上向きの解錠位置と下向きの施錠位置とに亘ってほぼ１８０度の範囲で操作する時には突部５２が切欠部５３内で移動し、第２軸５１は回転しない。
室外側操作部材５を上向きの施錠位置と下向きの解錠位置とに亘ってほぼ１８０度の範囲で操作することで、第２軸５１が回転して変換機構１１で杆体１２が上下移動して受け部８が上下に移動する。
室外側操作部材５が施錠位置の時には受け部８は第２位置で、解錠位置の時に受け部８が第１位置に移動する。
【００３３】
このようであるから、室外側操作部材５を施錠位置として受け部８を第２位置に保持した状態で、室内側操作部材４を解錠位置から矢印ａ方向に操作して施錠位置とした時には突部５２が仮想線で示すように第２軸５１の切欠端面５３ａと接近、好ましくは接する。
この状態で室外側操作部材５を施錠位置から矢印ｂ方向に操作して第２軸５１を矢印ｂ方向に回転すると、その切欠端面５３ａが突部５２に接し、第１軸５０を回転して室内側操作部材４を矢印ｃで示すように解錠位置に向けて回転する。
これとともに受け部８が第２位置から第１位置に移動する。
【００３４】
したがって、室内側操作部材４を解錠位置とした時には受け部８が第２位置であるから、障子２を開放すると受け部８がストッパ部７に当接して開放ストロークを制限する。
また、室内側操作部材４が施錠位置の状態で、室外側操作部材５を施錠位置から解錠位置に向けて操作すると錠装置３が解錠されると共に、受け部８が第１位置となるので、障子２を全開できる。
なお、第１軸５０に変換機構１１を取付け、室内側操作部材４で受け部８を上下に移動するようにしても良い。
【００３５】
前記各実施の形態における変換機構１１の具体例を図８と図９に基づいて説明する。
２枚のプレート６０を間隔を置いて連結し、この２枚のプレート６０間に亘って回転子６１と回転板６２を回転自在に設けると共に、第１・第２可動板６３，６４を移動自在に設ける。前記回転子６１は操作部材９で回転される軸１０が嵌合する角孔６１ａを有すると共に、突起６１ｂを有する。
前記第１・第２可動板６３，６４は長手方向の長孔６３ａ，６４ａを有し、この長孔６３ａ，６４ａに前記プレート６０に設けたガイドピン６５が摺動自在に挿通し、第１・第２可動板６３，６４はプレート６０に対して長手方向に移動自在に支承される。
前記第１・第２可動板６３，６４の長手方向の一端部が回転板６２にピン６６でそれぞれ連結され、回転板６２が回転すると第１・第２可動板６３，６４が反対方向に移動する。
前記突起６１ｂにアーム６７がピン６８で連結され、このアーム６７が第１可動板６３にピン６９で連結され、回転子６１が回転すると第１可動板６３が移動する。
【００３６】
前記回転子６１が回転するとアーム６７を介して第１可動板６３が移動する。
第１可動板６３が移動すると回転板６２が回転し、第２可動板６４が反対方向に移動する。例えば、第１可動板６３が下方に移動すると第２可動板６４が上方に移動する。
【００３７】
このようであるから、図１に示す実施の形態の場合には第１可動板６３に杆体１２を連結して受け部８を移動する。
図４に示す実施の形態の場合には第１・第２可動板６３，６４に杆体１２をそれぞれ連結し、上摺動片４０と下摺動片４１を上下に移動する。
【００３８】
以上の各実施の形態は、外動片引きサッシについて述べたが、内動片引きサッシ、引き違いサッシでも良い。
【００３９】

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a sliding sash used mainly in schools, hospitals, and the like.
[0002]
[Prior art]
Sliding sashes include a sliding sash in which the inner sash and the outer sash are movably mounted in the in-plane direction on the sash frame, and an externally movable sash in which the sash is slidably mounted in the in-plane direction on the outside of the sash frame. 2. Description of the Related Art There are known sashes, inward moving draw sashes and the like in which a shoji is movably mounted in an in-plane direction on the indoor side of a sash frame.
[0003]
Sliding sashes used in schools, hospitals, etc., are designed so that the opening width of the sash when opening the sash is smaller than the full opening width by limiting the opening stroke of the sash to prevent the sash from being fully opened. It is known to prevent a person from accidentally falling from a department.
For example, a sliding sash for limiting the opening stroke of a shoji is disclosed in Japanese Utility Model Laid-Open No. 4-1190088 (U.S. Patent No. 2,542,821).
In this sliding sash, a fixing member is attached to a lower frame of a sash frame, and a receiving block is attached to a lower frame of a shoji mounted on the outdoor side of the sash frame, and the receiving block hits a stopper to limit the opening stroke of the shoji. Things.
[0004]
Sliding has also been proposed so that it can be opened from the outside of the room and used as an emergency entrance in the event of an emergency such as a fire.
For example, Japanese Patent Laying-Open No. 8-165627 discloses a sliding sash in which an outer handle can be used to unlock a sash, and in an emergency, the sash can be unlocked and opened by operating the outer handle from outside. ing.
[0005]
[Problems to be solved by the invention]
By mounting the above-mentioned fixing member and the receiving block and providing the above-mentioned outer handle, it is possible to limit the opening stroke of the sash and to provide a sliding sash which can be opened from the outdoor.
However, in the sliding sash as described above, when the outer handle is unlocked by operating the outer handle from the outdoor to open the sash, the opening stroke of the sash is limited due to the fixing member and the receiving block, and the sash cannot be fully opened. .
For this reason, the opening width of the sash when the sash is opened from the outside is small, and it is not preferable as an emergency entrance because it is difficult for people to enter and exit.
[0006]
The present invention has been made in view of the above-described problems, and its object is to limit the opening stroke when opening a sash from indoors, and to fully open the sash when opening the sash from outdoors without limiting the opening stroke. The purpose is to provide a sliding sash.
[0007]

BEST MODE FOR CARRYING OUT THE INVENTION
A first embodiment of the present invention will be described with reference to FIG.
A sash frame 1 is provided with a sliding door 2 so as to be openable and closable in an in-plane direction to form a sliding sash.
A lock device 3 is provided which can lock and unlock the shoji in the closed position, lock and unlock from inside the room, and unlock from outside the room.
For example, an indoor operation member 4 attached to the indoor side portion of the shoji 2 and an outdoor operation portion 5 attached to the outdoor side portion are provided. By operating the indoor operation member 4, locking and unlocking can be performed. It can be unlocked by operating the member 5. In addition, you may make it lockable.
An opening restriction device 6 is provided to limit the opening stroke of the sash 2 across the sash frame 1 and the sash 2.
The opening restriction device 6 can be operated from inside or outside the room to a restricted state in which the opening stroke of the sash 2 is smaller than the full opening and a non-restricted state in which the opening stroke is fully opened.
For example, a stopper 7 provided on the sash frame 1, a receiving portion 8 provided on the shoji 2, and an operating member 9 are provided, and the receiving 8 does not come into contact with the stopper 7 when the shoji 2 is opened. The receiving portion 8 is movable between a first position and a second position by operating the operating member 9 from inside the room.
[0018]
In the embodiment shown in FIG. 1, the receiving portion 8 moves up and down to an upper position (first position) indicated by a dotted line and a lower position (second position) indicated by a two-dot chain line, and is rotated by an operation member (handle) 9. A conversion mechanism 11 such as a Gremon mechanism for converting rotation into reciprocating motion is provided on the shaft 10, and a receiving portion 8 is connected to a rod 12 that is moved up and down by the conversion mechanism 11.
When the receiving portion 8 is at the upper position, the position of the stopper portion 7 in the height direction is shifted and the receiving portion 8 does not abut on the stopper portion 7 even when the sash 2 is opened (that is, it is in an unrestricted state).
When the receiving portion 8 is at the lower position, the height is the same as that of the stopper portion 7, and when the sash 2 is opened, the receiving portion 8 comes into contact with the stopper portion 7 (that is, is in a restricted state).
Note that the height of the stopper portion 7 may be different from that of the stopper portion 7 when the receiving portion 8 is at the upper position, and may be different from the height of the stopper portion 7 when the receiving portion 8 is at the lower position.
