Description

【0001】
【発明の属する技術分野】
本発明は、ドアの内側にドアを施解錠するスライド式のロック手段を設置し、反対の外側にドアの施解錠状態を表示する表示手段を設置してなるドアロック装置の技術分野に属する。詳しくは、ロック手段に備えるロックバーと取付ブロックとをスライド自在に係合し、ロックバーを、施錠位置と解錠位置の間で摺動させてドアを施解錠すると同時に、ロックバーの摺動に連動してドアの施解錠状態を切換表示するスライド式ドアロック装置に適用し得る。本発明は、特に、そのようなスライド式ドアロック装置の部品取付構造に関する。
【0002】
【従来の技術】
従来、この種のスライド式ドアロック装置の中に、これをドアに組み付けるために、たとえば図10に示すような部品取付構造を備える構成にしたものがある。
【0003】
この従来のスライド式ドアロック装置では、ドアDを間に挟んで内側に取り付けるスライド式のロック手段Rと、反対の外側に取り付ける表示手段Sを備えている。
【0004】
ロック手段Rは、樹脂製の取付ブロック1と、略みぞ形の金属製ロックバー2とを備える。取付ブロック1は、互いに嵌め合い可能な形状に成形された、ベースプレート3およびストッパプレート4の2体に分割してなり、一方のベースプレート3に、内周に雌ねじ穴を有する管軸状のスタッドaを組み付け、他方のストッパプレート4に、一端にピニオンbを有する回転支軸c、ストッパ金属片dなどを組み付ける構成になっている。ストッパプレート4には、その角縁に、ストッパ金属片dの取付位置とは反対側にL状に曲げ延びる弾性片4aが突設されている。ロックバー2は、その溝部開口縁に、互いに対向して断面略L形状に曲げ延びる係合片2aを有するが、その係合片2aの一側に、その一部を切り欠いて突き当て段部2bを設け、他側にラック2cが設けられている。
【0005】
表示手段Sは、扇形の表示窓5aを設けた取手ケース5と、樹脂製の取付プレート6を備え、取付プレート6に管軸状の回転受軸eと表示板fとが組み付けられる。そして、取手ケース5に取付プレート6を嵌入させて組み立てられる。
【0006】
一方、ロック手段Rを組み立てるときは、ベースプレート3にスタッドaをEリングで止めて立設し、ストッパプレート4にストッパ金属片dをねじ止めする。さらに、ベースプレート3の中心挿通穴3aに回転支軸cを挿通させ、ストッパプレート4とベースプレート3との間でピニオンbを組み込む。そして、ストッパプレート4を、そのストッパ金属片d側をベースプレート3の嵌合凹部3bに嵌め合わせて、取付ブロック1を組み立てる。
【0007】
しかる後、この取付ブロック1をロックバー2に係合し、マイナスドライバ等を使って弾性片4aを押え付けながらロックバー2をスライドさせ、取付ブロック1を、ストッパ金属片dが突き当て段部2b間に位置する摺動規制位置にセットする。すると、弾性片4aの弾性復帰力でストッパプレート4が、ストッパ金属片dと突き当て段部2bとの係合高さ位置まで押し上げられる。そして、ロックバー2の両端にキャップ7を被せると、ロック手段Rが組み立てられる。
【0008】
組み立てたロック手段Rは、ドアDの内側から、回転支軸cとスタッドaをそれぞれドアDの取付穴8a〜8cに挿通する一方、表示手段Sは、ドアDの外側から、回転受軸eを中間の取付穴8aに挿通して回転支軸cと係合する。そして、長ネジgを取付穴8b・8cに通してスタッドaに捩じ込み、ロック手段Rと表示手段SとをドアDを挟んで締着する。こうしてスライド式ロック装置がドアDに組み付けられる。
【0009】
そこで、斯かる取付構造からなる従来のスライド式ロック装置では、ロックバー2を、ストッパ金属片dが突き当て段部2bに突き当たる摺動規制範囲の間でスライドさせると、それに応じてドアDが施解錠される。一方、ロックバー2が摺動すると、ラック2cと噛み合うピニオンbが回転し、その回転を、回転支軸cと回転受軸eの係合を介し伝達して表示板fを回動し、その回動方向に応じて、表示窓aから臨む表示板fの異なる区分表示面を切り換えて、ドアDの施解錠状態を外部に表示するようになっている。
【0010】
【発明が解決しようとする課題】
ところが、上述した従来のスライド式ドアロック装置の部品取付構造では、ロック手段Rの取付ブロック1を、ベースプレート3とストッパプレート4の2体に分割し、その間で、スタッドa・ピニオンb・ストッパ金属片dなどを組み付ける複雑な構成であるため、部品点数が極めて多くなり、それだけコスト高になるという課題があった。
【0011】
また、ベースプレート3とストッパプレート4の2体間に、ピニオンb等の部品を組み付ける必要があるため、各々組み付け易い方向を選んで組み込んだり、取り付けやすいように逐一持ち変えて組み込んだり、しかも、いちいち弾性片4aを押えながら組み立てなければならず、組立作業にとても手間を要し、面倒である。反対に、修理点検などのために分解する場合も、同様に分解作業に手間取り、面倒であるという課題があった。
【0012】
さらに、従来では、ストッパプレート4の弾性片4aによってストッパ金属片dを突き当て段部2bとの所定係合高さ位置まで押し上げて位置決めする構成であるが、これでは、ロックバー2のスライド操作の繰り返しによって、経時、弾性片4aが磨耗したり破損したりする結果、ストッパ金属片dが突き当て段部2bとの所定係合位置から外れやすく、それが原因で、ドアDの施解錠不能などの不具合が発生するという課題もあった。
【0013】
そこで、本発明の目的は、上述のようなスライド式ドアロック装置において、部品点数を削減して構造を簡略化し、組立・分解作業を手間なく簡単にするとともに、ドアの施解錠動作の不具合が発生することのない部品取付構造を提供することにある。
【0014】
【課題を解決するための手段】
したがって、上記目的を達成すべく、請求項1に記載の発明は、たとえば以下に示す図示実施の形態のとおり、ドアDを間に挟んで内側にドアDを施解錠するロック手段Aを、外側にドアDの施解錠状態を表示する表示手段Bを取り付けて締着してなり、前記ロック手段Aに備える略みぞ形のロックバー10と取付ブロック11とをスライド自在に係合し、前記ロックバー10を、その施錠位置と解錠位置の間で摺動させてドアDを施解錠すると同時に、そのロックバー10の摺動をラックピニオン機構で回転運動に変換し、その回転を前記表示手段Bに伝達して表示板26を回動して表示窓30からドアDの施解錠状態を切換表示するスライド式ドアロック装置において、前記ロックバー10には、その溝部開口縁にあって互いに対向して断面略L形状に曲げ延びる係合片13の両側又はいずれか一側に、前記施錠位置と解錠位置間で摺動範囲を規制する突き当て段部13a・13bを設けるとともに、長さ方向両端側における前記ロックバー10の施錠位置と解錠位置に、前記ラックピニオン機構のピニオン18と噛み合う両端歯部を、前記ロックバーの溝部底面に対して同じ高さ位置に形成したラック10bを設け、且つ長さ方向端部を開放してそこに前記取付ブロック11の差込み口14を設ける一方、前記取付ブロック11には、前記ラック10bと噛み合うピニオン18と、前記突き当て段部13a・13bに当てて前記摺動範囲を規定するストッパ20とを含む取付部品を個々に組み付ける取付部15a〜15cを、対応する取付部品の外形状に合わせて同じ部品組付け面11aに設け、該取付ブロック11を、その部品組付け面11aを前記ロックバー10の溝部開口12に対し上向きにして前記差込み口14から前記ロックバー10の前記係合片13に係合し、前記取付部品を、各々が対応する前記取付部15a〜15cに組み付けて前記ロック手段Aを組み立て、前記ロックバー10をスライドさせてドアDを施解錠すると、このロックバー10の摺動に応じて前記施錠位置と前記解錠位置にある前記ラック10bの両端歯部に前記ピニオン18が噛み合って回転し、その回転を伝達して前記表示板26を回動し、その回動方向に応じて該表示板26の異なる区分表示面を切り換えてなることを特徴とする。
【0015】
【発明の実施の形態】
以下、図面を参照しつつ、本発明の実施の形態について説明する。
【0016】
図1は、本発明による部品取付構造を適用したスライド式ドアロック装置を示す分解斜視図である。図2は、スライド式ドアロック装置に備えるロック手段を示す組立斜視図である。図3は、スライド式ドアロック装置の平面図である。図示例のスライド式ドアロック装置は、ドアDを間に挟んで内側に取り付けるロック手段Aと、反対の外側に取り付ける表示手段Bとを備えてなる。
【0017】
ロック手段Aは、たとえば金属製のロックバー10と樹脂製の取付ブロック11とを備える。図示例のロックバー10は、略みぞ形に成形するが、特に、溝部開口12の開口縁に、互いに対向して断面略L形状に曲げ延びる係合片13を設けた変形みぞ形に形成する。そして、両側面の中間部を溝部開口12寄りに若干湾曲させて、そこに把持部10aを形成するとともに、一端部は、溝部を開放し、そこに取付ブロック11の差込み口14を設けた外形状に形成してなる。
【0018】
さらに、ロックバー10は、係合片13の一側を一部切り欠いて、そこにロックバー10の施錠位置と解錠位置間で摺動範囲を規制する突き当て段部13a・13bを設けてなる。一方、溝部内には、図3に示すように、突き当て段部13a・13bの下側に長手方向に沿って内向きにラック10bを設ける。ラック10bは、その長さ方向に設ける歯部のうち、両端側におけるロックバー10の施錠位置と解錠位置の歯部を、同じ高さ位置に形成する一方、その間の残りの中間歯部を、一段低く溝部底面寄りの高さ位置に形成してなる。
【0019】
取付ブロック11は、たとえばインサート樹脂成形により作製し、樹脂製の取付本体部15と、その両側面に長手方向に沿って突設したガイドレール部16を一体に形成するとともに、金属プレートを埋設し、そのプレートに基端を固着したスタッド17を部品組付け面11aから突出するように立設してなる。スタッド17は、内周に雌ねじ穴を螺設した管軸状の金属製連結杆である。
【0020】
さらに、樹脂製の取付本体部15には、部品組付け面11a上に、後述する取付部品を組み付ける複数の取付部15a・15b・15cを設けてなる。そのうち第1の取付部15aは、ピニオン18を組み込むために、その外形に合わせて形成した貫通穴からなる。第2の取付部15bは、ピニオン18の付勢ばね19を組み込むために、その外形に合わせて形成した一対の平行な差込み細溝からなる。第3の取付部15cは、ストッパ20を組み付けるために、その外形に合わせて形成した矩形の切欠きからなる。
【0021】
ピニオン18は、樹脂成形により軸部18aの一端にピニオンギヤ18bを設ける一方、他端を太径に成形しそこにバネ押え部18cを形成するとともに、該バネ押え部の端面から軸部18aの長さ方向に深く係合穴22を穿設してなる。この係合穴22に、ピニオン18の回転を伝達する回転支軸23を係合させる構成になっている。そのため、係合穴22は、回転支軸23の断面形状に合わせて、回転伝達可能な略矩形状に穿設されている。
【0022】
付勢ばね19は、それぞれU形状に屈曲させた一対のばね性を有する針金材からなる。ストッパ20は、比較的肉厚な金属片をL板状に曲げ成形し、一片にねじ止め板部20aを形成する一方、他片に突き当て板部20bを形成してなる。なお、図中符号24は、取付ブロック11の部品組付け面11aに被せる外装カバーである。したがって、外装カバー24には、スタッド17およびバネ押え部18cを通す挿通穴24aが設けられている。
【0023】
一方、表示手段Bは、表示板26と取手ケース27および取付金具28を備える。表示板26は、円板26aの裏面中心に管軸状の回転受軸26bを立設してなる。回転受軸26bの中空穴26cは、上記回転支軸23の断面形状に合わせて略矩形状に穿設された貫通穴で、円板26aの中心を貫通している。なお、中空穴26cは、その深さ方向中段位置から円板26a中心の開口までの穴形状を、より細径に形成し、中段穴位置に段差を設けてなる。円板26aには、その表面を2つに色分けし、ドアDの施解錠状態を識別できるように区分表示面が施されている。
【0024】
取手ケース27は、キャップ状をなし、その楕円状表面の中心に、回転受軸26bの中空穴26cを臨ませる操作穴27aを設け、その操作穴27aと隣接してに表示窓30が開けられている。取付金具28は、箱形本体部28aに、表示板26の回転受軸26bを通す挿通穴31を設け、その箱形本体部28aの両端に、対称なねじ止め用の鍔部28bを突設してなる。
【0025】
さて、上述した構成のスライド式ドアロック装置をドアDに取り付けるに当たり、予めロック手段Aを組み立てるが、そのとき、特に、取付ブロック11は、部品組付け面11aをロックバー10の溝部開口12に対し上向きにして、差込み口14からガイドレール部16を差し込んで係止片13に係止し、スライドさせてロックバー10に係合セットする。
【0026】
しかる後、図2に示すように、ロックバー10に対し部品組込み面11aが上向きの取付ブロック11をセット状態のまま、各取付部15a〜15cに、全て外側の図中上方から、各々が対応する取付部品18〜20を組み付ける。
【0027】
すなわち、ピニオン18は、ピニオンギヤ18bとばね押え部18cとで、その間に付勢ばね19を略平行に挟持させた状態にして、ピニオンギヤ18bを取付部15a内に組み込むとともに、付勢ばね19を取付部15bに差し入れて組み込む。ストッパ20は、ねじ止め板部20aを取付部15cに嵌め込んで突き当て板部20bを取付ブロック11の側面に当てがい、ねじ止め板部20aを止めネジ33により固着する。そして、ピニオン18の係合穴22内に回転支軸23を係合して挿着してから、取付ブロック11の部品組込み面11aに、図1に示す外装カバー24を被せる。このようにしてロック手段Aが組み立てられる。
【0028】
こうしてロック手段Aを組み立てる一方、表示手段Bの側では、取付金具28を、取付穴x・y・zが予め穿設されたドアDの所定取付位置に組み付ける。すなわち、取付金具28は、その挿通穴31を、中間の取付穴yに合わせてドアDの所定取付位置にねじ止めする。次いで、ロック手段Aの側において、ドアDの内側から、回転支軸23とスタッド17をそれぞれ取付穴x・y・zに挿通する一方、外側の表示手段Bの側から、表示板26の回転受軸26bを中間の取付穴yに挿通し、回転支軸23に係合させる。また、長ネジ29をスタッド17の雌ねじ穴に捩じ込み、ロック手段Aを、間にドアDを挟んで表示手段Bの取付金具28に締着する。そして、表示板26を覆って取付金具28に取手ケース27を被せ、それを取付金具28にビス止めする。こうしてスライド式ロック装置が、図4に示すようにドアDに組み付けられる。
【0029】
斯かる部品取付構造からなる図示スライド式ロック装置は、使用時にドアDをロックする場合は、ロックバー10を持って図4中矢示方向に摺動させる。そして、ロックバー10が摺動ストローク(摺動範囲)Lの距離だけスライドしたとき、図5に示すようにストッパ20の突き当て板部20bが一側の突き当て段部13aに突き当たり、ロックバー10のスライドを止める。すると、図4中鎖線で示すとおり、ロックバー10がドアDとドア支持枠P間に跨る位置まで突出し、ドアDが施錠される。なお、図4中符号35は、この施錠時、ロックバー10の差込み口14に有する係合凹部14aが係合する止め具である。
【0030】
一方、ドアDをロック解除する場合は、ロックバー10を矢示方向と反対向きに摺動ストロークLの距離だけ摺動させる。つまり、図2に示すようにストッパ20の突き当て板部20bが他側の突き当て段部13bに突き当たって止まる位置までスライドさせて、ドアDのロックを解除する。
【0031】
このようにロックバー10をスライドさせてドアDを施解錠すると、同時に、ロックバー10の摺動に応じて、ラック10bの施錠位置と解錠位置にある両端歯部とピニオンギヤ18bが噛み合って回転し、その回転を、回転支軸23と回転受軸26bとの係合を介し伝達して表示板26を回動し、その回動方向に応じて、表示窓30から臨む表示板26の異なる区分表示面が切り換えられ、その都度、ドアDの施解錠状態が外部に表示される。
【0032】
なお、ドアDがロック状態にあるとき、トラブル発生時など、ドアDの外側から非常解錠する必要があるときは、図示省略するが、専用の非常解錠用キーを使用する。その場合は、非常解錠用キーの細長な先端キー部分を、表示板26の中空穴26cの中段位置まで差し込み、取付ブロック11の付勢ばね19に抗してピニオン18を押し込んで、ピニオンギア18bを、ラック10bにおける下段位置の中間歯部に噛み合わせる。そして、非常解錠用キーを回動してピニオン18を回転させる。すると、ラック10bとの噛み合いを介してロックバー10が解錠位置へとスライドし、ドアDが解錠される。
【0033】
ところで、本発明は、上述したロック手段Aを、それに代えて以下に示すように構成することもできる。図6は、本発明による部品取付構造を適用した他のスライド式ドアロック装置に備えるロック手段A´を示す分解斜視図である。なお、上述した図示実施の形態における構成部分と同様な構成部分については、図中同一符号を付して以下に説明する。
【0034】
この他の図示実施の形態では、ロックバー10を摺動規制するストッパとして、図中符号40で示すフラットで細長な略矩形状の金属プレートを用い、該ストッパ40を、取付ブロック11の部品組付け面11aを覆う外装カバーとしても機能させる構成になっている。そこで、ストッパ40は、特に本体のねじ止め板部40aを、取付ブロック11の部品組付け面11aに合わせて略同じ大きさの細長な矩形状に形成し、ねじ止め板部40aの一端から横向きに突き当て板部40bを突設した形状になっている。そして、ねじ止め板部40aには、スタッド17と、ピニオン18の軸部18aを各々挿通させる挿通穴41・42を設けるとともに、ねじ挿通穴43が設けられている。
【0035】
さらに、取付ブロック11には、部品組付け面11aの四方外縁から立壁を枠状に立ち上げて収納空間を設け、そこにストッパ40の取付部15cを形成している。また、図示他例において、ピニオン18には、ピニオンギヤ18bの歯面側中心にばね収納穴(図示省略)を設け、該ばね収納穴内に、順次、ピニオン用付勢ばねのコイルスプリング44と、金属製ボール45を嵌め込む構成になっている。そのため、部品組付け面11a、即ち取付部15c内の底面には、上記ばね収納穴内でコイルスプリング44とボール45が嵌め込み状態のピニオンギヤ18bを組み込むために、その外形状に合わせて取付部15aとして貫通穴を設けてなる。
【0036】
そこで、ロック手段A´を組み立てるときは、上述した図示例と同様に、取付ブロック11を、部品組付け面11aを上向きにして差込み口14からロックバー10に係合セットして後、図7に示すように、全て外側の図中上方から、対応する取付部に各取付部品を組み付ける。
【0037】
すなわち、上記ばね収納穴に嵌め込み一部突出状態のボール45を下向きにして、ピニオン18のピニオンギヤ18bを取付部15aに組み込む。ストッパ40は、スタッド17と、ピニオン18の軸部18aを挿通穴41・42に挿通させて取付部15cに嵌め付け、止めネジ48により固着する。このストッパ40の取付状態において、ねじ止め板部40aで部品組付け面11aを覆うとともに、突き当て板部40bが取付部15cの切欠き穴49から外向きに突出する。このようにしてロック手段A´が組み立てられる。
【0038】
そして、図示他例において、スライド式ロック装置の使用時、ドアDをロックする場合は、上述したと同様に、ロックバー10を持って施錠位置へ摺動させると、図8に示すように、ストッパ40の突き当て板部40bが一側の突き当て段部13aに突き当たり、ロックバー10のスライドを止める。
【0039】
一方、ドアDを解錠する場合は、ロックバー10を反対の解錠位置へ摺動させ、図7に示すように、ストッパ40の突き当て板部40bが他側の突き当て段部13bに突き当たって止まる解錠位置までスライドさせて、ドアDのロックを解除する。
【0040】
また、上述した図示実施の形態において、ロックバー10には、係合片13の一側に突き当て段部13a・13bを設け、それら突き当て段部にストッパ20・40を当てて摺動範囲を規定する構成であった。しかし、本発明は、図示省略するが、ロックバーの両側係合片の双方に、同様な突き当て段部を設け、それら両側の突き当て段部にストッパを当てて摺動範囲を規定する構成にすることもできる。
【0041】
したがって、この他例において、ストッパは、たとえば図9中符号50で示すとおり、上述したと同様に比較的肉厚な金属片を用いるが、特にねじ止め板部50aの両端を互いに対向する同じ向きに屈曲させ、その両曲げ片に突き当て板部50b・50bを形成してなる。一方、取付ブロック11には、部品組付け面11a上のストッパ取付位置に、ストッパ50の外形状に合わせた切欠き凹部からなる取付部15cを形成してなる。
【0042】
そこで、ロック手段Aの組立時、この取付部15cにストッパ50を嵌め込み、両突き当て板部50bが取付ブロック11の側面から出っ張った状態で、ねじ止め板部50aにて止めネジ33により固着する。そして、ドアの施解錠時は、両突き当て板部50b・50bがそれぞれロックバーにおける両側の突き当て段部に当たってロックバーの摺動範囲を規定する。
【0043】
なお、以上の図示実施の形態において、スタッド17は、インサート成形により埋設した金属プレート上に固着して取付ブロック11に立設した構成であった。しかし、スタッド17は、取付ブロックの部品組付け面に、例えばねじ止めして立設する構成にすることもできる。その場合には、ピニオン18など他の取付部品と同様、部品組付け面にスタッド17を組み付けるために、その基端部形状に対応させて、ねじ穴形状の取付部を設ける構成にすればよい。
【0044】
このように本発明では、以上に例示したピニオン18やストッパ20・40・50等の取付部品とは別に、他種の適宜取付部品を取付ブロックに組み付けてロック手段を構成する場合でも、他の取付部品を組み付けるために対応する取付部を、同じ部品組付け面に設ける構成にすればよい。これによって、必要な各種の取付部品を、取付ブロックの同じ部品組付け面に対し、その外側の上方から、簡単に取り付けることができる。
【0045】
【発明の効果】
上述の如く構成した本発明によれば、次のような効果が得られる。
【0046】
請求項1に記載の発明によれば、ピニオンやストッパを含む各取付部品を組み付ける取付部を、対応する取付部品の外形状に合わせて取付ブロックの同じ部品組付け面に設け、その取付ブロックを、部品組付け面をロックバーの溝部開口に対し上向きにして差込み口からロックバーの係合片に係合し、取付部品を、各々が対応する取付部に組み付けてロック手段を組み立てる部品取付構成であるため、取付ブロックに対し、常にその外側の同じ上方から、必要な各種の取付部品を取り付けることができ、その結果、従来の如く、取付部品を、いちいち組み付け易い方向を選んで組み込んだり、取り付けやすいように持ち変えて組み込んだりする面倒な組立・分解工程を伴うことがなく、組立・分解作業を著しく手間なく簡単ににすることができる。
【0047】
さらに、ロック手段の取付ブロックを、従来の如く2体に分割しその間に部品を取り付ける構成ではなく、単体の取付ブロックの同じ部品組付け面に対し取付部品を取り付ける簡略な構成であるため、それだけ部品点数が削減され、コストを著しく低減させることもできる。加えて、取付ブロックにストッパを所定位置に位置決める弾性片のような位置決め部を設ける必要がなく、そのため、従来の如くロックバーのスライド操作の繰り返しによって弾性片が磨耗したり破損したりする問題もなく、その結果、ストッパが突き当て段部との所定係合位置から外れて、ドアの施解錠不能などの不具合が発生することを防止してドアの施解錠動作を安定させることができる。

[0004]
The locking means R includes a resin mounting block 1 and a substantially groove-shaped metal lock bar 2. The mounting block 1 is divided into two bodies, a base plate 3 and a stopper plate 4, which are molded into a shape that can be fitted together, and one base plate 3 has a tube-shaft stud a having a female screw hole on the inner periphery. And the rotation support shaft c having the pinion b at one end, the stopper metal piece d and the like are assembled to the other stopper plate 4. The stopper plate 4 is provided with an elastic piece 4a that protrudes from the corner edge of the stopper plate 4 and extends in an L shape on the opposite side of the mounting position of the stopper metal piece d. The lock bar 2 has an engaging piece 2a that is bent to have a substantially L-shaped cross section facing each other at the opening edge of the groove, but a part of the engaging bar 2a is cut out on one side of the engaging piece 2a. A portion 2b is provided, and a rack 2c is provided on the other side.
[0005]
The display means S includes a handle case 5 provided with a fan-shaped display window 5 a and a resin mounting plate 6, and a tube-shaped rotation receiving shaft e and a display plate f are assembled to the mounting plate 6. Then, the mounting plate 6 is fitted into the handle case 5 and assembled.

[0025]
Now, when the sliding door lock device having the above-described configuration is attached to the door D, the lock means A is assembled in advance. At this time, in particular, the attachment block 11 has the component assembly surface 11a in the groove opening 12 of the lock bar 10. On the other hand, the guide rail portion 16 is inserted through the insertion port 14 so as to be locked to the locking piece 13, and is slid and set to the lock bar 10.
[0026]
After that, as shown in FIG. 2, the mounting blocks 11 with the component mounting surface 11a facing upward with respect to the lock bar 10 remain set, and the mounting portions 15a to 15c all correspond to the mounting portions 15a to 15c from the upper side in the drawing. The mounting parts 18 to 20 to be assembled are assembled.
[0027]
In other words, the pinion 18 includes the pinion gear 18b and the spring retainer 18c so that the biasing spring 19 is sandwiched between the pinion gear 18b and the pinion gear 18b in the mounting portion 15a. It is inserted into the part 15b and incorporated. In the stopper 20, the screwing plate portion 20 a is fitted into the mounting portion 15 c, the butting plate portion 20 b is applied to the side surface of the mounting block 11, and the screwing plate portion 20 a is fixed by the set screw 33. Then, after the rotational support shaft 23 is engaged and inserted into the engagement hole 22 of the pinion 18, the exterior cover 24 shown in FIG. 1 is put on the component mounting surface 11 a of the mounting block 11. In this way, the locking means A is assembled.
[0028]
While the locking means A is assembled in this way, on the display means B side, the mounting bracket 28 is assembled at a predetermined mounting position of the door D in which mounting holes x, y, and z are previously drilled. That is, the mounting bracket 28 is screwed at a predetermined mounting position of the door D with the insertion hole 31 aligned with the intermediate mounting hole y. Next, on the lock means A side, the rotation support shaft 23 and the stud 17 are respectively inserted into the mounting holes x, y, and z from the inside of the door D, while the display plate 26 is rotated from the outside display means B side. The receiving shaft 26 b is inserted into the intermediate mounting hole y and engaged with the rotating support shaft 23. Further, the long screw 29 is screwed into the female screw hole of the stud 17, and the locking means A is fastened to the mounting bracket 28 of the display means B with the door D interposed therebetween. Then, the display plate 26 is covered and a handle case 27 is put on the mounting bracket 28, and it is screwed to the mounting bracket 28. In this way, the sliding lock device is assembled to the door D as shown in FIG.
[0029]
When the door D is locked at the time of use, the illustrated slide type locking device having such a component mounting structure is slid in the direction indicated by the arrow in FIG. When the lock bar 10 is slid by the distance of the sliding stroke (sliding range) L, as shown in FIG. 5, the abutting plate portion 20b of the stopper 20 abuts against the abutting step portion 13a, and the lock bar 10 Stop 10 slides. Then, as shown by a chain line in FIG. 4, the lock bar 10 protrudes to a position straddling between the door D and the door support frame P, and the door D is locked. In addition, the code | symbol 35 in FIG. 4 is a stopper with which the engaging recessed part 14a which has in the insertion port 14 of the lock bar 10 engages at the time of this locking.
[0030]
On the other hand, when unlocking the door D, the lock bar 10 is slid by the distance of the sliding stroke L in the direction opposite to the arrow direction. That is, as shown in FIG. 2, the door D is unlocked by sliding the stopper plate 20 b of the stopper 20 to a position where it stops against the other bump portion 13 b.
[0031]
When the door D is locked and unlocked by sliding the lock bar 10 in this manner, at the same time, the both ends of the rack 10b in the locked position and the unlocked position mesh with the pinion gear 18b and rotate according to the sliding of the lock bar 10. Then, the rotation is transmitted through the engagement between the rotation support shaft 23 and the rotation receiving shaft 26b to rotate the display plate 26, and the display plate 26 facing the display window 30 differs depending on the rotation direction. The division display surface is switched, and the lock / unlock state of the door D is displayed outside each time.
[0032]
In addition, when the door D is in the locked state and when it is necessary to perform emergency unlocking from the outside of the door D, such as when a trouble occurs, a dedicated emergency unlocking key is used although not shown. In that case, the elongated key part of the emergency unlocking key is inserted to the middle position of the hollow hole 26c of the display plate 26, and the pinion 18 is pushed against the biasing spring 19 of the mounting block 11, and the pinion gear. 18b is meshed with the intermediate tooth portion at the lower position in the rack 10b. Then, the emergency unlocking key is rotated to rotate the pinion 18. Then, the lock bar 10 slides to the unlocking position through the meshing with the rack 10b, and the door D is unlocked.
[0033]
By the way, in the present invention, the locking means A described above can be configured as shown below instead. FIG. 6 is an exploded perspective view showing a lock means A ′ provided in another sliding door lock device to which the component mounting structure according to the present invention is applied. In addition, about the component similar to the component in embodiment shown above, it attaches | subjects the same code | symbol in a figure, and demonstrates it below.
[0034]
In the other illustrated embodiment, a flat and thin, substantially rectangular metal plate denoted by reference numeral 40 in the figure is used as a stopper for restricting sliding of the lock bar 10, and the stopper 40 is used as a component assembly of the mounting block 11. It is configured to function as an exterior cover that covers the attachment surface 11a. Therefore, the stopper 40 is formed by forming the screwing plate portion 40a of the main body into an elongated rectangular shape having substantially the same size in accordance with the component assembly surface 11a of the mounting block 11, and laterally extending from one end of the screwing plate portion 40a. The abutting plate portion 40b is projected. The screwing plate portion 40a is provided with insertion holes 41 and 42 through which the stud 17 and the shaft portion 18a of the pinion 18 are inserted, and a screw insertion hole 43 is provided.
[0035]
Further, the mounting block 11 is provided with a storage space by raising a standing wall in a frame shape from the four outer edges of the component assembly surface 11a, and the mounting portion 15c of the stopper 40 is formed there. In another example shown in the figure, the pinion 18 is provided with a spring housing hole (not shown) at the center of the tooth surface of the pinion gear 18b, and a coil spring 44 of a pinion urging spring and a metal are sequentially placed in the spring housing hole. The ball 45 is inserted. Therefore, in order to incorporate the pinion gear 18b in which the coil spring 44 and the ball 45 are fitted in the spring housing hole on the component assembly surface 11a, that is, the bottom surface in the mounting portion 15c, the mounting portion 15a is adapted to the outer shape. A through hole is provided.
[0036]
Therefore, when assembling the locking means A ′, the mounting block 11 is engaged and set to the lock bar 10 from the insertion port 14 with the component assembling surface 11a facing upward, as in the above-described example of FIG. As shown in Fig. 4, each mounting component is assembled to the corresponding mounting portion from the upper side in the outer drawing.
[0037]
That is, the pinion gear 18b of the pinion 18 is assembled into the mounting portion 15a with the ball 45, which is fitted into the spring housing hole and partially protrudes, facing downward. The stopper 40 has the stud 17 and the shaft portion 18a of the pinion 18 inserted through the insertion holes 41 and 42, fitted into the mounting portion 15c, and fixed by the set screw 48. In the mounting state of the stopper 40, the component assembly surface 11 a is covered with the screwing plate portion 40 a, and the abutting plate portion 40 b protrudes outward from the cutout hole 49 of the mounting portion 15 c. In this way, the locking means A ′ is assembled.
[0038]
In the other example shown in the figure, when using the sliding lock device, when locking the door D, as described above, when the slide bar is slid to the locking position with the lock bar 10, as shown in FIG. The abutting plate portion 40b of the stopper 40 abuts against one abutting step portion 13a, and stops the lock bar 10 from sliding.
[0039]
On the other hand, when unlocking the door D, the lock bar 10 is slid to the opposite unlocking position, and the abutting plate portion 40b of the stopper 40 is moved to the abutting step portion 13b on the other side as shown in FIG. The door D is slid to the unlocking position where it stops, and the door D is unlocked.
[0040]
In the illustrated embodiment described above, the lock bar 10 is provided with abutting step portions 13a and 13b on one side of the engaging piece 13, and the stoppers 20 and 40 are applied to the abutting step portions to slide the lock bar 10. It was the composition which prescribes. However, in the present invention, although not shown in the drawings, a similar abutting step portion is provided on both side engaging pieces of the lock bar, and a stopper is applied to the abutting step portions on both sides to define a sliding range. It can also be.
[0041]
Therefore, in this other example, as shown by reference numeral 50 in FIG. 9, for example, the stopper uses a relatively thick metal piece as described above, but in particular, the same direction in which both ends of the screwing plate portion 50a face each other. And abutting plate portions 50b and 50b are formed on both bent pieces. On the other hand, the attachment block 11 is formed with an attachment portion 15c formed of a notch recess adapted to the outer shape of the stopper 50 at a stopper attachment position on the component assembly surface 11a.
[0042]
Therefore, when the lock means A is assembled, the stopper 50 is fitted into the mounting portion 15c, and the both abutting plate portions 50b protrude from the side surface of the mounting block 11 and are fixed by the set screw 33 at the screwing plate portion 50a. . When the door is locked and unlocked, the both abutting plate portions 50b and 50b abut against the abutting step portions on both sides of the lock bar to define the sliding range of the lock bar.
[0043]
In the above-described illustrated embodiment, the stud 17 is configured to be fixed on the metal plate embedded by insert molding and erected on the mounting block 11. However, the stud 17 may be configured to stand upright, for example, by screwing on the component assembly surface of the mounting block. In that case, as with other mounting parts such as the pinion 18, in order to assemble the stud 17 on the part mounting surface, a screw hole-shaped mounting part may be provided corresponding to the shape of the base end part. .
[0044]
Thus, in the present invention, in addition to the mounting parts such as the pinion 18 and the stoppers 20, 40, 50, and the like exemplified above, even when other types of appropriate mounting parts are assembled to the mounting block to configure the locking means, What is necessary is just to make it the structure which provides the attachment part corresponding in order to assemble | attach an attachment component in the same component assembly surface. Thereby, various necessary attachment parts can be easily attached to the same part assembly surface of the attachment block from above the outside.
[0045]
【The invention's effect】
According to the present invention configured as described above, the following effects can be obtained.
[0046]
According to the first aspect of the present invention, an attachment portion for assembling each attachment component including a pinion and a stopper is provided on the same component assembly surface of the attachment block in accordance with the outer shape of the corresponding attachment component. A component mounting configuration in which the part assembly surface is directed upward with respect to the groove opening of the lock bar, and the engagement part of the lock bar is engaged from the insertion port, and the locking parts are assembled by assembling the mounting parts to the corresponding mounting parts. Therefore, it is possible to always attach various necessary mounting parts to the mounting block from the same upper side of the outside.As a result, as in the past, the mounting parts are assembled by selecting the direction in which they are easily assembled, There is no complicated assembly / disassembly process to change and incorporate for easy installation, and the assembly / disassembly work can be remarkably simplified without much trouble. That.
[0047]
Furthermore, it is not a structure in which the mounting block of the locking means is divided into two bodies as in the past and parts are attached between them, but it is a simple structure in which mounting parts are attached to the same part assembly surface of a single mounting block. The number of parts is reduced, and the cost can be significantly reduced. In addition, there is no need to provide a positioning portion such as an elastic piece for positioning the stopper at a predetermined position on the mounting block. Therefore, the elastic piece is worn or damaged due to repeated sliding operation of the lock bar as in the past. As a result, it is possible to prevent the stopper from being disengaged from the predetermined engagement position with the abutting stepped portion, and to prevent problems such as the inability to lock and unlock the door, and to stabilize the door locking and unlocking operation.
