【０００１】
【産業上の利用分野】
本発明は、内障子に取り付けられる錠本体と外障子に取り付けられる受け部材とから構成される引戸錠に関し、詳しくは、錠本体と受け部材とを所定の位置関係で容易に取り付けることができるようにした引戸錠に関するものである。
【０００２】
【従来の技術】
引戸錠には図５に示すように、段違いに接合する内障子Ａと外障子Ｂとを施錠する召合わせ錠がある。内障子Ａには鎌形係止片１０１を有する錠本体１００が取り付けられ、外障子Ｂには前記鎌形係止片１０１と係合する窓部１３１を形成した受け部材１３０が取り付けられる。
【０００３】
錠本体１００は図６に示すように、受け部材１３０と対向する第１の固定板１１０と反対側の第２の固定板１２０とによって内障子Ａを挟み、第１と第２の固定板１１０，１２０間に、鎌形係止片１０１が配置される。第１の固定板１１０には、鎌形係止片１０１が出入りするための窓部１１１が穿設されるとともに、外障子Ｂ側から鎌形係止片１０１を回動させるためのピン嵌合部１１２が取り付けられる。
【０００４】
第２の固定板１２０は中央部を窪ませてスリット１２１が形成され、窪みの中に内障子Ａ側から鎌形係止片１０１を回動させる摘まみ１２２が配置される。摘まみ１２２の内端部には可動板１２３が接続され、可動板１２３が上下動することにより、鎌形係止片１０１が回動する。また、第１の固定板１１０と可動板１２３とには、鎌形係止片１０１が錠本体１００内に収納された状態において、連続する位置関係となる小孔１１４，１２４が穿設される。このような錠本体１００は、第１の固定板１１０と第２の固定板１２０とが内障子Ａを挟んだ状態で、複数のネジ１０２，１０２に締めつけられることによって、内障子Ａに取り付けられる。
【０００５】
外障子Ｂに取り付けられる受け部材１３０は、錠本体１００と対向する固定板１３２に鍔部１３３を有する箱型のケース１３４を取り付け、固定板１３２には鎌形係止片１０１が出入りする窓部１３１が穿設され、さらに固定板１３２とケース１３４とにはシリンダー１３５が取り付けられる。また、固定板１３２には錠本体１００の第１の固定板１１０と可動板１２３とに穿設した小孔１１４，１２４と連続する小孔１３６が穿設される。
【０００６】
受け部材１３０を取り付ける外障子Ｂは、ケース１３４の深さ分の間隔をあけて２枚のプレート１４０，１４１から構成される。内障子Ａと対向するプレート１４０には、固定板１３２に穿設した窓部１３１からシリンダー１３５が配置される部分まで窓部１４２が穿設される。この窓部１４２の周辺が固定板１３２とケース１３４の鍔部１３３とで挟まれ、ネジ１４３によって締めつけられることによって、受け部材１３０が外障子Ｂに取り付けられる。そしてシリンダー１３５が他方のプレート１４１の外側から取り付けられる。
【０００７】
錠本体１００を取り付けた内障子Ａと、受け部材１３０を取り付けた外障子Ｂとが、図５に示すように段違いに接合し、図６の仮想線のように、錠本体１００の摘まみ１２２を下げると可動板１２３が下降し、鎌形係止片１０１が回動して受け部材１３０の窓部１３１と係合する。また、外障子Ｂの外側からシリンダー１３５に鍵（図示せず）を差し込んで回すと、シリンダー１３５内のピン１３８が突出して錠本体１００のピン嵌合部１１２内に嵌入し、歯車（図示せず）が回転して可動板１２３が下降し、鎌形係止片１０１が受け部材１３０の窓部１３１と係合する。このようにして、内障子Ａと外障子Ｂとが施錠される。
【０００８】
【発明が解決しようとする課題】
引戸錠を内障子Ａと外障子Ｂとに取り付ける際は、シリンダー１３５内のピン１３８が突出して錠本体１００のピン嵌合部１１２内に嵌入し、また錠本体１００の鎌形係止片１０１が受け部材１３０の開口１３１と係合するように位置合わせする必要がある。この位置合わせは、受け部材１３０が外障子Ｂに取り付けられた後、錠本体１００を内障子Ａに仮締めし、その後、錠本体１００の第２の固定板１２０のスリット１２１および可動板１２３と第１の固定板１１０に穿設されたそれぞれの小孔１２４，１１４が、受け部材１３０の小孔１３６と連続するようにして行う。各小孔１２４，１１４，１３６が連続しているかどうかは、第２の固定板１２０の小孔から目視することによって判断される。
【０００９】
ところが、外障子Ｂと内障子Ａとの間隔は狭くて暗いため、受け部材１３０の小孔１３６を目視することが困難であった。しかも、第２の固定板１２０のスリット１２１の幅を広くして、可動板１２３に穿設した小孔１３６を大きくすることは、第２の固定板１２０側が人目に触れる面であるから外観が損なわれる。したがって、外観を損ねないようにするため、スリット１２１の幅や小孔１３６は小さくせざるを得なかった。また、外観を損ねない工夫として、小孔１３６に装飾的な半透明な蓋が設けられていた。このため、第２の小手板１２０の小孔を目視しにくく、錠本体１００を位置決めする作業性が悪いといった不具合があった。
【００１０】
そこで本発明は、錠本体と受け部材とを所定の位置関係で容易に取り付けることができるようにした引戸錠を提供することを目的とする。
【００１１】
【課題を解決するための手段】
上記目的を達成するための第１の手段は、錠本体内に収納される鎌形係止片が出入りする窓部を穿設した裏板と、鎌形係止片を窓部から出入りさせる摘まみ付きのスライド部材と、前記スライド部材の摘まみが上下動できるような長孔を形成し、スライド部材を収納する表板とを具備した引戸錠において、上記スライド部材の摘まみに貫通孔を穿設し、上記裏板に前記貫通孔と連続する検出孔を穿設し、スライド部材の貫通孔が裏板の検出孔と連続する位置でスライド部材を一旦、停止させる係止体を具備したことを特徴とする引戸錠である。
【００１２】
また第２の手段は、錠本体と受け部材によって構成され、前記錠本体は、錠本体内に収納される鎌形係止片が出入りする窓部を穿設した裏板と、鎌形係止片を窓部から出入りさせる摘まみ付きのスライド部材と、前記スライド部材の摘まみが上下動できるような長孔を形成し、スライド部材を収納する表板とを具備し、受け部材は窓部を有する引戸錠において、錠本体は、上記スライド部材の摘まみに貫通孔を穿設し、前記貫通孔に栓体を着脱自在に挿入し、上記裏板に前記貫通孔と連続する検出孔を穿設し、受け部材は、鎌形係止片が窓部と係合できる位置において錠本体側の検出孔と連続するように抜け穴が穿設されていることを特徴とする引戸錠である。
【００１３】
さらに第３の手段は、錠本体と受け部材によって構成され、前記錠本体は、錠本体内に収納される鎌形係止片が出入りする窓部を穿設した裏板と、鎌形係止片を窓部から出入りさせる摘まみ付きのスライド部材と、前記スライド部材の摘まみが上下動できるような長孔を形成し、スライド部材を収納する表板と、可動板を備え、受け部材は窓部を有し、可動板が下降すると、鎌形係止片は受け部材の窓部と係合する引戸錠において、上記スライド部材の摘まみに貫通孔を穿設し、前記貫通孔に栓体を着脱自在に挿入し、上記裏板に前記貫通孔と連続する検出孔を穿設し、さらに前記栓体は、可動板と嵌合し、栓体がスライド部材の貫通孔から引き抜かれると、摘まみが摘まれてスライド部材が上昇しても、可動板が上昇しないことを特徴とする引戸錠である。
【００１４】
【作用】
上記手段によれば、スライド部材の貫通孔から栓体を抜いた状態で裏板に穿設した検出孔から向こう側を目視する。また、あるいは栓体を抜いた状態で、検出孔から向こう側の受け部材に穿設した抜け穴へ櫛を差し込む。貫通孔は摘まみに穿設するものであるから、比較的大きなものとしても、栓体を装着することにより、外観が損なわれることがない。
【００１５】
また上記手段によれば、スライド部材が係止体によって、一旦停止した位置で、スライド部材の貫通孔から裏板の検出孔の向こう側を目視することができる。
【００１６】
【実施例】
本発明に係る実施例を、図１乃至図４を参照して説明する。図１は、鎌形係止片を錠本体内に収納した状態での正面断面図である。図２は、表板の背面図である。図３は、位置合わせをする状態での正面断面図である。図４は、施錠した状態での正面断面図である。
【００１７】
本発明に係る引戸錠の錠本体１は、受け部材７０と対向する裏板１０と、反対側の表板２０とによって内障子Ａを挟み、裏板１０と表板２０との間に各種部品が収納される。裏板１０には、鎌形係止片２が出入りするための窓部１１と、後述するロックピン７２が出入りするための貫通孔１２と、前記窓部１１と貫通孔１２との間に位置する検出孔１３とが穿設される。
【００１８】
このような裏板１０に平面形状がコ字形の固定板３０が開口部３１を表板２０側にして接合される。裏板１０と接合する固定板３０の背面部３２にも、裏板１０の窓部１１、貫通孔１２および検出孔１３と連続した窓部３３、丸孔３４および連通孔３５が穿設される。固定板３０の窓部３３は、裏板１０の窓部１１と同様に、鎌形係止片２が出入りできるようにするものである。丸孔３４には歯車（図示せず）を周設したピン嵌合部３６が取り付けられる。さらに、連通孔３５にはパイプ３７が接続される。
【００１９】
このような固定板３０内に、平面形状がコ字形の可動板４０が開口部４１を裏板１０側にして収納される。固定板３０の開口部３１は可動板４０の背面部４２によって半分以上、塞がれる。可動板４０の背面部４２には、後述するスライド部材６０に装着したロッド状の栓体６３の先端部を貫通する嵌合孔４３と、錠本体１の位置を調整する検出孔４４が穿設される。可動板４０の検出孔４４は固定板３０に取り付けられたパイプ３７と連続する位置に穿設する。可動板４０には固定板３０に取り付けられたピン嵌合部３６の歯車と噛合してラックのように機能する連続穴（図示せず）が形成される。
【００２０】
可動板４０内には、回動する鎌形係止片２が収納される。鎌形係止片２は固定ピン３と可動ピン４とが貫通し、固定ピン３は固定板３０に固着され、さらに可動ピン４の両端部は固定板３０に形成された一対のＬ字形の案内溝（図示せず）と嵌合する。そして、可動板４０にはこの可動ピン４が移動する溝部４５が形成される。
【００２１】
可動板４０の背面部４２は、正面形状がコ字形の蓋板５０と接合し、この蓋板５０は固定板３０の開口部３１を閉塞する。可動板４０の背面部４２が蓋板５０に接合することによって、可動板４０は円滑に上下動することができる。また、可動板４０の背面部４２側の上端と固定板３０とがコイルバネ５によって係合され、可動板４０が上側に位置している際に、コイルバネ５が可動板４０を蓋板５０に付勢し、可動板４０が仮固定されて、容易に下降しないようにされる。蓋板５０の中央には、後述する栓体６３が貫通して上下動できるようにするための長孔５１が穿設される。蓋板５０の両端部には鍔部５２，５２が形成され、この鍔部５２，５２には雌ネジが形成されたスペーサ６，６が配置される。
【００２２】
他方、表板２０の裏板１０側には凹嵌部２１が形成され、この凹嵌部２１内に、中央に摘まみ６１を形成した亠字形のスライド部材６０が上下動できるように収納される。表板２０の中央には摘まみ６１が上下動できるように長孔２２が穿設される。凹嵌部２１内に収納されたスライド部材６０は、長孔２３を穿設した被覆板２４によって塞がれる。スライド部材６０の摘まみ６１には貫通孔６２が穿設され、この貫通孔６２にＴ字形のロッド状の栓体６３が着脱自在に挿入される。栓体６３の先端部は、被覆板２４の長孔２３、蓋板５０の長孔５１および可動板４０の嵌合孔４３を貫通し、摘まみ６１を上下動させると、連動して可動板４０も連動する。
【００２３】
また、表板２０の凹嵌部２１の下寄りの位置には、図２に示すように、バネのような係止体２５が突出し、下降したスライド部材６０が一旦、この係止体２５によって停止するようにする。この一旦、停止した位置で、栓体６３をスライド部材６０の貫通孔６２から抜かれると、この貫通孔６２と可動板４０の検出孔４４および固定板３０のパイプ３７とが連続した位置関係となる。係止体２５は例えば凹嵌部２１と淵部２６との間に針金状の部材を折曲し、凹嵌部２１内にＶ字形部分を突出させたものとすることができる。
【００２４】
さらに、スライド部材６０の内側の面であって、貫通孔６２に若干入り込む位置に細溝６４が形成され、この細溝６４内に筋金６５が嵌入される。他方、栓体６３にも貫通孔６２に完全に挿入した状態で、この筋金６５と係合する溝部６６が刻設される。
【００２５】
他方、受け部材７０は従来と同様の機構であるが、固定板３０に取り付けられたピン嵌合部３６内に、シリンダー７１内から突出するロックピン７２が嵌入し、鎌形係止片２が窓部７３と係合できる位置で、固定板３０に取り付けられたパイプ３７と連続するように抜け穴７４が穿設される。
【００２６】
本発明にかかる引戸錠は以上のように構成され、次に取付方法について図３を参照しながら説明する。
【００２７】
受け部材７０が外障子Ｂに取り付けられれた後、錠本体１を内障子Ａに仮締めする。錠本体１のスライド部材６０が上側に位置し、鎌形係止片２が錠本体１内に収納された状態で、錠本体１と受け部材７０とが対向するようにする。そして、作業者がスライド部材６０の貫通孔６２から栓体６３を引き抜くと、自重によってスライド部材６０が落下する。しかし、表板２０の凹嵌部２１の下方には係止体２５が突出しているため、スライド部材６０はこの係止体２５によって中間位置で一旦、停止する。
【００２８】
スライド部材６０が中間に位置すると、スライド部材６０の貫通孔６２と可動板４０の検出孔４４と固定板３０に取り付けられたパイプ３７とが連通し、しかも被覆板２４と蓋板５０には長孔２３，５１が穿設されているため、スライド部材６０の貫通孔６２から裏板１０と対向している受け部材７０を容易に目視することができる。
【００２９】
受け部材７０には位置合わせをするための抜け穴７４が穿設されているため、スライド部材６０の貫通孔６２から受け部材７０の抜け穴７４を目視することができると、錠本体１が所定の位置にあることを確認することができる。また、スライド部材６０の貫通孔６２から受け部材７０の抜け穴７４を目視できないときは、目視できるように錠本体１の位置をずらせる。このようにして錠本体１の取付位置は容易に調整することができる。錠本体１の取付位置が調整された後、錠本体１を仮固定した状態から本固定すると、錠本体１の取付作業が終了する。
【００３０】
また、もう一つの有力な取付方法として、上記した目視する方法に代えて、スライド部材６０の貫通孔６２からパイプ３７を突き抜け、受け部材７０の抜け穴７４に櫛（図示せず）が貫通するように錠本体１の位置を調整することもできる。櫛はパイプ３７によって方向が規制されるため、錠本体１の位置がずれているときは、櫛が受け部材７０の抜け穴７４を貫通できない。スライド部材６０の貫通孔６２からパイプ３７を突き抜けた櫛が受け部材７０の抜け穴７４を貫通できるように錠本体１の位置をずらせ、錠本体１の位置を調整する。
【００３１】
次に、段違いに接合する内障子Ａと外障子Ｂとを施錠する方法について、図４を参照しながら説明する。
【００３２】
使用者が摘まみ６１を摘んで、上側に位置しているスライド部材６０を下側に位置させる。このとき、スライド部材６０の貫通孔６２を貫通している栓体６３は、可動板４０の嵌合孔４３と嵌合しているため、可動板４０も同時に下降する。さらに、可動板４０の溝部４５の入口部４６が、鎌形係止片２を貫通している可動ピン４を押し下げる。可動ピン４の両端部は固定板３０に形成されたＬ字形の案内溝（図示せず）に案内されて下方へ移動する。スライド部材６０が中間位置まで下降したとき、可動ピン４はＬ字形の案内溝の折曲部に位置する。さらに、スライド部材６０が下降すると、可動ピン４は案内溝の折曲端部まで移動し、可動板４０が下降することによって、可動ピン４は可動板４０の溝部４５の奥部４７に入り込む。したがって、可動ピン４が移動できなくなった状態で、鎌形係止片２が固定板３０の窓部３３と裏板１０の窓部１１とから突出し、受け部材７０の窓部７３と係合することによって、施錠される。
【００３３】
逆に、解錠するときは、使用者が摘まみ６１を摘んで下側に位置しているスライド部材６０を上昇させる。スライド部材６０が中間の位置まで上昇している間は、可動ピン４は可動板４０の溝部４５内を奥部４７側から入口部４６の方へ移動するだけで、鎌形係止片３は固定板３０の窓部３３と裏板１０の窓部１１とから突出した状態を維持する。スライド部材６０が中間位置から更に上昇すると、可動ピン４が可動板４０の溝部４５の入口部４６に挟まれた状態となり、可動ピン４は強制的に固定板３０の案内溝内を上昇させられ、鎌形係止片３は錠本体１内に収納される。
【００３４】
本発明に係る錠本体１は以上のような機構によって動作するため、スライド部材６０が下側に位置した状態で、スライド部材６０の貫通孔６２を貫通している栓体６３を引き抜くと、鍵を掛けた状態とすることができる。すなわち、鎌形係止片３は可動板４０が上昇することによって、受け部材７０の窓部７３と係合した状態から錠本体１内に収納されるため、可動板４０が上昇しなければ、鎌形係止片３は受け部材７０の窓部７３と係合した状態を維持する。可動板４０は嵌合孔４３と係止している栓体６３によって上下動するため、栓体６３がスライド部材６０の貫通孔６２から引き抜かれると、摘まみ６１が摘まれてスライド部材６０が上昇しても、可動板４０は上昇しない。したがって、栓体６３をスライド部材６０の貫通孔６２から引き抜くことによって、鍵が掛けられた状態とすることができる。
【００３５】
他方、外障子Ｂに取り付けられた受け部材によって施錠・解錠するときも、鎌形係止片３は上記と同様の動作をする。すなわち、受け部材のシリンダー７１に鍵を差し込んで回すと、シリンダー７１内のロックピン７２が錠本体１のピン嵌合部３６内に嵌入し、ピン嵌合部３６が回転する。ピン嵌合部３６の周囲には歯車（図示せず）が周設されており、その歯車は可動板４０に形成された連続穴と噛合しているため、鍵の回転すなわちピン嵌合部３６の回転によって、可動板４０が上下動する。上述したように、可動板４０が下降すると、鎌形係止片３は受け部材７０の窓部７３と係合し、鍵が抜かれると施錠される。解錠するときは、鍵によってロックピン７２をピン嵌合部３６内に嵌入し、鍵を回転させて可動板４０を上昇させ、鎌形係止片３を錠本体１内に収納する。
【００３６】
なお、本発明は上記実施例に限定することなく、本発明の要旨内において設計変更することができる。
【００３７】
【発明の効果】
本発明は、スライド部材の摘まみに貫通孔を穿設し、その貫通孔によって裏板に穿設した検出孔の向こう側、すなわち受け部材の検出孔を目視するものである。摘まみに穿設する貫通孔は、栓体によって塞がれるため、比較的大きくしても、外観を損なうことがない。したがって、スライド部材の摘まみに比較的大きな貫通孔を穿設したことにより、受け部材の検出孔を目視することが容易になり、錠本体を取り付ける際の作業性が向上する。

The present invention relates to a sliding door lock.
[0002]
[Prior art]
As a sliding door lock, as shown in FIG. 5, there is a combination lock that locks an inner sash A and an outer sash B that are connected at different levels. A lock body 100 having a sickle-shaped locking piece 101 is attached to the inner sash A, and a receiving member 130 having a window 131 formed to engage with the sickle-shaped locking piece 101 is attached to the outer sash B.
[0003]
As shown in FIG. 6, the lock body 100 sandwiches the inner shroud A by a first fixing plate 110 facing the receiving member 130 and a second fixing plate 120 on the opposite side, and the first and second fixing plates 110. , 120, a sickle-shaped locking piece 101 is arranged. The first fixing plate 110 is provided with a window 111 through which the sickle-shaped locking piece 101 enters and exits, and a pin fitting portion 112 for rotating the sickle-shaped locking piece 101 from the side of the sash B. Is attached.
[0004]
A slit 121 is formed in the second fixing plate 120 by depressing the center portion thereof, and a knob 122 for rotating the sickle-shaped locking piece 101 from the side of the stomach A is disposed in the depression. A movable plate 123 is connected to the inner end of the knob 122, and the sickle-shaped locking piece 101 is rotated by moving the movable plate 123 up and down. The first fixed plate 110 and the movable plate 123 are provided with small holes 114 and 124 having a continuous positional relationship when the sickle-shaped locking piece 101 is housed in the lock body 100. Such a lock body 100 is attached to the inner shroud A by being tightened by the plurality of screws 102 with the first fixed plate 110 and the second fixed plate 120 sandwiching the inner shroud A. .
[0005]
The receiving member 130 attached to the outer sliding door B has a box-shaped case 134 having a flange 133 attached to a fixing plate 132 facing the lock body 100, and the fixing plate 132 has a window 131 through which the sickle-shaped locking piece 101 enters and exits. , And a cylinder 135 is attached to the fixing plate 132 and the case 134. The fixed plate 132 is provided with a small hole 136 continuous with the small holes 114 and 124 formed in the first fixed plate 110 and the movable plate 123 of the lock body 100.
[0006]
The outer sliding door B to which the receiving member 130 is attached includes two plates 140 and 141 spaced from each other by the depth of the case 134. On the plate 140 facing the inner sash A, a window 142 is formed from the window 131 formed on the fixing plate 132 to a portion where the cylinder 135 is arranged. The periphery of the window 142 is sandwiched between the fixing plate 132 and the flange 133 of the case 134 and tightened by the screw 143, so that the receiving member 130 is attached to the outer sliding door B. Then, the cylinder 135 is attached from the outside of the other plate 141.
[0007]
The inner sash A to which the lock body 100 is attached and the outer sash B to which the receiving member 130 is attached are connected stepwise as shown in FIG. 5, and the knob 122 of the lock body 100 as shown by the phantom line in FIG. Is lowered, the movable plate 123 descends, and the sickle-shaped locking piece 101 rotates to engage with the window 131 of the receiving member 130. Also, when a key (not shown) is inserted into the cylinder 135 and turned from the outside of the shroud B, the pin 138 in the cylinder 135 projects and fits into the pin fitting portion 112 of the lock body 100, and the gear (not shown). ) Is rotated to move the movable plate 123 down, and the sickle-shaped locking piece 101 is engaged with the window 131 of the receiving member 130. In this way, the inner sash A and the outer sash B are locked.
[0008]
[Problems to be solved by the invention]
When the sliding door lock is attached to the inner sash A and the outer sash B, the pin 138 in the cylinder 135 projects and fits into the pin fitting portion 112 of the lock body 100, and the sickle-shaped locking piece 101 of the lock body 100 is It is necessary to perform alignment so as to engage with the opening 131 of the receiving member 130. In this alignment, after the receiving member 130 is attached to the outer sash B, the lock body 100 is temporarily tightened to the inner sash A, and then the slit 121 and the movable plate 123 of the second fixed plate 120 of the lock body 100 are fixed. The operation is performed so that the small holes 124 and 114 formed in the first fixing plate 110 are continuous with the small holes 136 of the receiving member 130. Whether or not the small holes 124, 114, and 136 are continuous is determined by visually observing the small holes of the second fixing plate 120.
[0009]
However, since the distance between the outer sash B and the inner sash A was narrow and dark, it was difficult to visually check the small holes 136 of the receiving member 130. In addition, increasing the width of the slit 121 of the second fixed plate 120 and increasing the size of the small hole 136 formed in the movable plate 123 is because the second fixed plate 120 side is a surface that can be seen by the public, and thus the appearance is reduced. Be impaired. Therefore, in order not to impair the appearance, the width of the slit 121 and the small hole 136 had to be reduced. In addition, as a device that does not impair the appearance, a decorative translucent lid is provided in the small hole 136. For this reason, there was a problem that it was difficult to visually recognize the small hole of the second small hand plate 120 and the workability of positioning the lock main body 100 was poor.
[0010]
Therefore, an object of the present invention is to provide a sliding door lock in which a lock body and a receiving member can be easily attached in a predetermined positional relationship.

[0025]
On the other hand, the receiving member 70 has the same mechanism as the conventional one, but the lock pin 72 protruding from the cylinder 71 is fitted into the pin fitting portion 36 attached to the fixing plate 30, and the sickle-shaped locking piece 2 is At a position where it can be engaged with the portion 73, a through hole 74 is formed so as to be continuous with the pipe 37 attached to the fixing plate 30.
[0026]
The sliding door lock according to the present invention is configured as described above. Next, a mounting method will be described with reference to FIG.
[0027]
After the receiving member 70 is attached to the outer sash B, the lock body 1 is temporarily fastened to the inner sash A. With the slide member 60 of the lock body 1 positioned on the upper side and the sickle-shaped locking piece 2 housed in the lock body 1, the lock body 1 and the receiving member 70 face each other. Then, when the worker pulls out the plug 63 from the through hole 62 of the slide member 60, the slide member 60 falls by its own weight. However, since the locking body 25 projects below the recessed portion 21 of the front plate 20, the slide member 60 is temporarily stopped at an intermediate position by the locking body 25.
[0028]
When the slide member 60 is located in the middle, the through hole 62 of the slide member 60, the detection hole 44 of the movable plate 40, and the pipe 37 attached to the fixed plate 30 communicate with each other. Since the holes 23 and 51 are formed, the receiving member 70 facing the back plate 10 can be easily viewed from the through hole 62 of the slide member 60.
[0029]
Since the receiving member 70 is provided with a through hole 74 for positioning, when the through hole 74 of the receiving member 70 can be visually checked from the through hole 62 of the slide member 60, the lock body 1 is positioned at a predetermined position. Can be confirmed. Further, when the through hole 74 of the receiving member 70 cannot be viewed from the through hole 62 of the slide member 60, the position of the lock body 1 is shifted so as to be visible. In this way, the mounting position of the lock body 1 can be easily adjusted. After the mounting position of the lock main body 1 is adjusted, when the lock main body 1 is fully fixed from the temporarily fixed state, the mounting operation of the lock main body 1 is completed.
[0030]
As another influential mounting method, a comb (not shown) penetrates the pipe 37 from the through hole 62 of the slide member 60 and penetrates the through hole 74 of the receiving member 70 instead of the visual method described above. The position of the lock body 1 can also be adjusted. Since the direction of the comb is regulated by the pipe 37, when the position of the lock main body 1 is shifted, the comb cannot pass through the through hole 74 of the receiving member 70. The position of the lock body 1 is shifted and the position of the lock body 1 is adjusted so that the comb that has penetrated the pipe 37 from the through hole 62 of the slide member 60 can pass through the through hole 74 of the receiving member 70.
[0031]
Next, a method of locking the inner sash A and the outer sash B, which are joined at different levels, will be described with reference to FIG.
[0032]
The user pinches the knob 61 to position the upper slide member 60 on the lower side. At this time, since the plug 63 penetrating through the through hole 62 of the slide member 60 is fitted into the fitting hole 43 of the movable plate 40, the movable plate 40 also descends at the same time. Further, the entrance 46 of the groove 45 of the movable plate 40 pushes down the movable pin 4 penetrating the sickle-shaped locking piece 2. Both ends of the movable pin 4 are guided by L-shaped guide grooves (not shown) formed in the fixed plate 30 and move downward. When the slide member 60 is lowered to the intermediate position, the movable pin 4 is located at the bent portion of the L-shaped guide groove. Further, when the slide member 60 descends, the movable pin 4 moves to the bent end of the guide groove, and the movable plate 40 descends, so that the movable pin 4 enters the deep portion 47 of the groove 45 of the movable plate 40. Therefore, with the movable pin 4 unable to move, the sickle-shaped locking piece 2 projects from the window 33 of the fixed plate 30 and the window 11 of the back plate 10 and engages with the window 73 of the receiving member 70. Is locked by
[0033]
Conversely, when unlocking, the user picks the knob 61 and raises the slide member 60 located below. While the slide member 60 is raised to the intermediate position, the movable pin 4 merely moves in the groove 45 of the movable plate 40 from the back part 47 toward the entrance part 46, and the sickle-shaped locking piece 3 is fixed. The state where it protrudes from the window 33 of the plate 30 and the window 11 of the back plate 10 is maintained. When the slide member 60 further rises from the intermediate position, the movable pin 4 is sandwiched between the entrance portions 46 of the groove portions 45 of the movable plate 40, and the movable pin 4 is forcibly raised in the guide groove of the fixed plate 30. The sickle-shaped locking piece 3 is stored in the lock body 1.
[0034]
Since the lock body 1 according to the present invention is operated by the above-described mechanism, when the plug 63 that passes through the through hole 62 of the slide member 60 is pulled out in a state where the slide member 60 is located on the lower side, the key is locked. Can be set. In other words, the sickle-shaped locking piece 3 is stored in the lock body 1 from the state in which the movable plate 40 is raised and is engaged with the window 73 of the receiving member 70. The locking piece 3 maintains the state of being engaged with the window 73 of the receiving member 70. Since the movable plate 40 moves up and down by the plug 63 locked with the fitting hole 43, when the plug 63 is pulled out from the through hole 62 of the slide member 60, the knob 61 is pinched and the slide member 60 is moved. Even if it rises, the movable plate 40 does not rise. Therefore, by pulling out the plug 63 from the through hole 62 of the slide member 60, the locked state can be obtained.
[0035]
On the other hand, when locking / unlocking is performed by the receiving member attached to the shoji, the sickle-shaped locking piece 3 operates in the same manner as described above. That is, when the key is inserted into the cylinder 71 of the receiving member and turned, the lock pin 72 in the cylinder 71 fits into the pin fitting portion 36 of the lock body 1 and the pin fitting portion 36 rotates. A gear (not shown) is provided around the pin fitting portion 36, and the gear meshes with a continuous hole formed in the movable plate 40. , The movable plate 40 moves up and down. As described above, when the movable plate 40 is lowered, the sickle-shaped locking piece 3 is engaged with the window 73 of the receiving member 70, and is locked when the key is removed. When unlocking, the lock pin 72 is fitted into the pin fitting portion 36 by the key, the key is rotated to raise the movable plate 40, and the sickle-shaped locking piece 3 is stored in the lock body 1.
[0036]
It should be noted that the present invention is not limited to the above-described embodiment, and can be modified within the scope of the present invention.
[0037]
【The invention's effect】
According to the present invention, a through hole is formed in the knob of the slide member, and the other side of the detection hole formed in the back plate, that is, the detection hole of the receiving member is visually observed by the through hole. Since the through hole formed in the knob is closed by the plug, even if it is relatively large, the appearance is not impaired. Therefore, by forming a relatively large through-hole in the knob of the slide member, it becomes easy to visually check the detection hole of the receiving member, and workability when attaching the lock body is improved.
