The operating mechanism is engaged with and disengaged from the strike portion of the outer casing, and the operating mechanism includes a first operating piece that locks the locking member based on rotation of the cylinder lock provided on the outer casing and the other of the cylinder lock. A second operation piece for unlocking the locking member based on the rotation of the cylinder lock, and the first operation piece and the second operation piece in the external lock case in response to an operation to the neutral position of the cylinder lock. The present invention relates to a sliding door lock having a return mechanism for retracting.

この種の引違戸錠としては、本発明に関連する先行技術文献情報として下記に示す特許文献1がある。
この特許文献1に記された引違戸錠では、操作片(アーム)のピニオン状の***作部が作動板のラックに噛合わされていない時に各操作片(アーム)の先端がストライク部から突出しないようにするための戻しばねが設けられているので、通常の非作動時には操作片(アーム)がストライク部に係入することがなく、内框と外框との引違いが円滑に行える。
As this type of sliding door lock, there is Patent Document 1 shown below as prior art document information related to the present invention.
In the sliding door lock described in Patent Document 1, the tip of each operation piece (arm) does not protrude from the strike portion when the pinion-like operated portion of the operation piece (arm) is not engaged with the rack of the operation plate. Since the return spring is provided, the operation piece (arm) is not engaged with the strike portion during normal non-operation, and the inner rod and the outer rod can be smoothly drawn.

特開平9−144406号公報(段落番号0026〜0027、図1)JP-A-9-144406 (paragraph numbers 0026 to 0027, FIG. 1)

しかし、特許文献1の引違戸錠では、第1操作片および第2操作片を外部錠ケース内に退避させる復帰機構として設けられた戻しばねがコイル状のねじりばねで構成されているために、1つのコイル状のねじりばねを取り付ける時の組立て作業、すなわち実際的には、ねじりばねの中央のループ部を水平軸に外嵌させたままで、ねじりばねの両端のそれぞれを、ねじりばねの付勢力に抗って第1操作片(アーム)と第2操作片(アーム)の基端部に設けたバネ掛けに引っ掛ける作業が、高度の熟練を要する煩雑な作業内容であるため、組立て効率が低かった。   However, in the sliding door lock of Patent Document 1, the return spring provided as a return mechanism for retracting the first operation piece and the second operation piece into the external lock case is constituted by a coiled torsion spring. Assembling work when one coiled torsion spring is attached, that is, in practice, with the central loop portion of the torsion spring being fitted on the horizontal shaft, both ends of the torsion spring are applied to the biasing force of the torsion spring. Therefore, the work of hooking on the spring hooks provided at the base end of the first operating piece (arm) and the second operating piece (arm) is a complicated work requiring a high degree of skill, so the assembly efficiency is low. It was.

したがって、本発明の目的は、上に例示した従来技術による引違戸錠の持つ前述した欠点に鑑み、特に復帰機構を構成する部位の組立てが容易で組立て効率も高い引違戸錠を、できるだけ部品点数を増やすことなく提供することにある。   Therefore, in view of the above-mentioned drawbacks of the conventional door sliding doors illustrated above, the object of the present invention is to make the sliding door doors as easy to assemble as possible and to make the parts of the return mechanism easy to assemble. It is to provide without increasing.

本発明の特徴構成は、内框に配置された内部錠ケースと外框に配置された外部錠ケースとを有し、前記内部錠ケースに支持された施錠部材が、前記外部錠ケースに設けられた操作機構によって外框のストライク部に係脱するように構成され、前記操作機構は、シリンダ錠と、前記シリンダ錠の一方への回動に基づいて前記施錠部材を施錠する第1操作片と、前記シリンダ錠の他方への回動に基づいて前記施錠部材を解錠する第2操作片と、前記シリンダ錠の中立位置への操作に応じて前記第1操作片および前記第2操作片を前記外部錠ケース内に退避させる復帰機構とを有する引違戸錠であって、
前記操作機構が、前記外部錠ケース内に往復移動可能に支持された単一の操作スライダを備え、前記単一の操作スライダの往路操作に基づいて前記第1操作片が操作され、前記操作スライダの復路操作に基づいて前記第2操作片が操作され、
前記復帰機構は、前記操作スライダを前記往路と前記復路との中間位置に付勢するべく前記操作スライダに取り付けられた圧縮コイルバネと、前記圧縮コイルバネの上端又は下端を前記外部錠ケースに対して係止する係止機構とを有することにある。
A characteristic configuration of the present invention includes an inner lock case disposed on an inner casing and an outer lock case disposed on an outer casing, and a locking member supported by the inner lock case is provided on the outer lock case. The operation mechanism is configured to be engaged with and disengaged from the strike portion of the outer casing, and the operation mechanism includes a cylinder lock and a first operation piece that locks the locking member based on rotation of the cylinder lock to one side. A second operation piece for unlocking the locking member based on the rotation of the cylinder lock to the other, and the first operation piece and the second operation piece in response to an operation to the neutral position of the cylinder lock. A sliding door lock having a return mechanism for retracting in the external lock case,
The operation mechanism includes a single operation slider supported so as to be reciprocally movable in the external lock case, and the first operation piece is operated based on a forward operation of the single operation slider. The second operation piece is operated based on the return path operation of
Said return mechanism is engaged a compression coil spring which is mounted on the operating slider in order to bias the operating slider to an intermediate position between the return path the said outward, the upper end or lower end of the compression coil spring to the external lock casing And a locking mechanism for stopping .

このような特徴構成を有するので、本発明による引違戸錠では、操作機構が、外部錠ケース内に往復移動可能に支持された単一の操作スライダを備える、また、復帰機構が第1操作片と第2操作片とに直接取り付けられるバネからなるのではなく、操作スライダに取り付けられた圧縮コイルバネからなる、そこで、組立て時には、先ず圧縮コイルバネを操作スライダに取り付けることで、復帰機構としての役目を果たす言わばサブアセンブリを作製し、次の工程として、このサブアセンブリ(実質的には圧縮コイルバネを取り付けた操作スライダである)を外部錠ケースに取り付ければ、復帰機構を構成する部位の組立てが完了する。ここで、圧縮コイルバネを操作スライダに取り付けるというサブアセンブリ作製の作業内容は熟練度を要しない簡単なものであり、その次の、サブアセンブリを外部錠ケースに取り付ける作業もまた熟練度を要しない簡単なものである。従って、従来技術で必要とされた、ねじりばねの中央のループ部を軸に外嵌させたままで、ねじりばねの両端のそれぞれを、ねじりばねの付勢力に抗って第1操作片と第2操作片の一部に引っ掛ける等の熟練を要する煩雑な作業が不要となり、特に復帰機構を構成する部位の組立てが容易で組立て効率も高い引違戸錠が得られた。また、本発明では、復帰機構の主体をなす圧縮コイルバネを第1操作片および第2操作片を操作するために元々必要な操作スライダ内に配置するという手法を取っているので、従来技術に比較しても部品点数が増えず、比較的高い組立て効率が維持される。 With such a characteristic configuration, in the sliding door lock according to the present invention, the operation mechanism includes a single operation slider supported so as to be reciprocally movable in the external lock case, and the return mechanism is the first operation piece. And a compression coil spring attached to the operation slider instead of a spring directly attached to the second operation piece. Therefore, at the time of assembly, the compression coil spring is first attached to the operation slider to serve as a return mechanism. In other words, a subassembly is produced, and as a next step, the subassembly (substantially an operation slider with a compression coil spring attached ) is attached to the external lock case, and the assembly of the parts constituting the return mechanism is completed. . Here, the work content of the sub-assembly production that attaches the compression coil spring to the operation slider is a simple one that does not require skill, and the next work that attaches the sub-assembly to the external lock case also does not require skill. It is a thing. Accordingly, the both ends of the torsion spring against the urging force of the torsion spring are kept against the biasing force of the torsion spring while the center loop portion of the torsion spring is fitted on the shaft, which is required in the prior art. A complicated operation requiring skill such as hooking on a part of the operation piece is not required, and in particular, a sliding door lock is obtained in which the part constituting the return mechanism is easily assembled and the assembly efficiency is high. Further, in the present invention, since the compression coil spring that forms the main body of the return mechanism is disposed in the operation slider that is originally necessary for operating the first operation piece and the second operation piece, it is compared with the prior art. However, the number of parts does not increase and a relatively high assembly efficiency is maintained.

特に、前記操作スライダは互いに対向した一対の側板を備え、前記一対の側板の間に2つのバネ受けが移動自在に収納されており、前記圧縮コイルバネが前記2つのバネ受けの間に前記バネ受けどうしを離間付勢するように介装されており、前記係止機構は、前記各バネ受けの前記外部錠ケースに対する移動を所定の範囲内に制限するために前記外部錠ケースに設けられたストッパからなる構成とすることができる。
このような構成にすれば、復帰機構を構成するサブアセンブリの組立ては、既に操作スライダの一対の側板の間に収納されている2つのバネ受けの間に圧縮コイルバネを押し込むだけで完了するので、非常に簡単で熟練を要さずに且つ確実に組立て作業が行える。因みに、このようなサブアセンブリを取り付けた引違戸錠を使用する場合、例えば、シリンダ錠の一方への回動に基づいて第1操作片が施錠部材を施錠する時には、一方のバネ受けはストッパに係止された状態で他方のバネ受けが圧縮コイルバネを押し縮めながら2つのバネ受けどうしが近接する形で、操作スライダの移動と第1操作片による施錠動作が行われて、シリンダ錠の中立位置に戻せば、圧縮コイルバネの伸張しようとする付勢力に基づいて、操作スライダが中間位置に復帰されて、第1操作片が退避する。
In particular, the operation slider includes a pair of side plates opposed to each other, two spring receivers are movably accommodated between the pair of side plates, and the compression coil spring is disposed between the two spring receivers. The locking mechanism is provided with a stopper provided on the external lock case in order to limit the movement of each spring receiver relative to the external lock case within a predetermined range. It can be set as the structure which becomes.
With such a configuration, the assembly of the subassembly constituting the return mechanism can be completed simply by pressing the compression coil spring between the two spring receivers already accommodated between the pair of side plates of the operation slider. Therefore, assembly work can be performed reliably without requiring skill. Incidentally, when a sliding door lock having such a subassembly is used, for example, when the first operating piece locks the locking member based on the rotation of the cylinder lock to one side, the one spring support serves as a stopper. in the form of other spring received in the engagement state is each other receives two springs while compressing press the compression coil spring is near, it is performed the locking operation by moving the first operating piece of the operating slider, the neutral position of the cylinder lock If it returns to (2), based on the urging | biasing force which the compression coil spring tends to expand | extend, an operation slider will be returned to an intermediate position and a 1st operation piece will evacuate.

より具体的には、前記バネ受けは、前記操作スライダの前記一対の側板の間に収容されるバネ受け本体と、前記バネ受け本体から左右に延びて更に前記側板外に突出した一対の突起部とを含み、前記ストッパは、前記突起部を受け入れるべく前記外部錠ケースに設けられた案内溝の両端部からなる構成とすることができる。
このような構成にすれば、圧縮コイルバネの両端部を押し縮め操作可能なバネ受けの突起部が外に突出した操作スライダが得られるので、この突起部が外部錠ケースの案内溝内に係入するように操作スライダを外部錠ケースに取り付けるだけで、外部錠ケースに設けられた案内溝の両端部が圧縮コイルバネの各端部の移動を制限するストッパとして作用し、復帰機構が完成するという合理的な構成が得られた。
More specifically, the spring receiver includes a spring receiver main body accommodated between the pair of side plates of the operation slider, and a pair of protrusions extending left and right from the spring receiver main body and further protruding out of the side plate. The stopper may be configured by both ends of guide grooves provided in the external lock case to receive the protrusion.
With this configuration, an operation slider is obtained in which the protrusions of the spring receiver that can be operated by pressing both ends of the compression coil spring protrude outward, so that these protrusions are engaged in the guide grooves of the external lock case. Just by attaching the operation slider to the external lock case, both ends of the guide groove provided in the external lock case act as stoppers to limit the movement of each end of the compression coil spring, and the return mechanism is completed. A typical configuration was obtained.

本発明によるその他の特徴および利点は、以下図面を用いた実施形態の説明により明らかになるであろう。   Other features and advantages of the present invention will become apparent from the following description of embodiments using the drawings.

本発明による引違戸錠について図面を参照しながら以下に解説する。
図1に示す引違戸錠100は、外框1(室外側引戸Aの框)に配置された外部ユニット10と内框2(室内側引戸Bの框)に配置された内部ユニット40とからなる。
The sliding door lock according to the present invention will be described below with reference to the drawings.
The sliding door lock 100 shown in FIG. 1 includes an external unit 10 disposed on the outer casing 1 (the casing of the outdoor sliding door A) and an inner unit 40 disposed on the inner casing 2 (the casing of the indoor sliding door B). .

(外部ユニット10の構成)

(Configuration of external unit 10)
As shown in FIGS. 1 to 3, the external unit 10 includes an external lock case 11 housed in a cavity of the outer casing 1, and an external makeup that fixes the outer lock case 11 with the outer casing 1 sandwiched therebetween. A seat 12 and an external plate 13 are provided. A cylinder lock 14 that is operated by a key K is provided inside the outer decorative seat 12, and a tail that rotates clockwise or counterclockwise according to the operation by the key K from the back surface of the outer decorative seat 12. 14a extends. The external lock case 11 includes a housing-like external lock case body 11p and a plate-like external lock case lid 11q.

外部錠ケース11は、テール14aの回動に応じて回転操作されるピニオン15、ピニオン15と噛合しピニオン15の回動に応じて上下に移動操作されるラック板16、ラック板16と一体的に上下移動するようにラック板16の上端に係止された操作スライダ20(操作機構の一例)、外部錠ケース本体11pの内面から横向きに立設されたアームピン11sに揺動自在に支持された施錠アーム30a(第1操作片の一例)と解錠アーム30b(第2操作片の一例)を備えている。図4から図6に示すように、施錠アーム30aと解錠アーム30bは、揺動軸芯から一方に延びたフック状の操作部31a,31bを有し、揺動軸芯から他方に離間した位置には***作ピン32a,32bが立設されている。外部錠ケース11には、キーKによるシリンダ錠14の中立位置への復帰に応じて、施錠アーム30aと解錠アーム30bを外部錠ケース11内に退避した状態に戻す復帰機構が設けられている。   The external lock case 11 is integrated with the pinion 15 that is rotated according to the rotation of the tail 14 a, the rack plate 16 that meshes with the pinion 15 and is moved up and down according to the rotation of the pinion 15, and the rack plate 16. An operation slider 20 (an example of an operation mechanism) locked to the upper end of the rack plate 16 so as to move up and down, and is swingably supported by arm pins 11s erected sideways from the inner surface of the external lock case body 11p. A locking arm 30a (an example of a first operation piece) and an unlocking arm 30b (an example of a second operation piece) are provided. As shown in FIGS. 4 to 6, the locking arm 30a and the unlocking arm 30b have hook-like operation portions 31a and 31b extending from the swing axis to one side, and are spaced apart from the other from the swing axis. The operated pins 32a and 32b are erected at the positions. The external lock case 11 is provided with a return mechanism for returning the locking arm 30a and the unlocking arm 30b to the state of being retracted in the external lock case 11 in response to the return of the cylinder lock 14 to the neutral position by the key K. .

図5に示すように、操作スライダ20は、金属板を打ち抜き加工並びに折り曲げ加工して得られた部材であり、互いに対向するように平行に延びた一対の側板21,22と、一対の側板21,22どうしを一体的に連結する連結部23とを備える。一方の側板21には***作ピン32aを介して施錠アーム30aを揺動操作する第1操作凹部21aが形成されており、他方の側板22には***作ピン32bを介して解錠アーム30bを揺動操作する第2操作凹部22aが形成されている。また各側板21,22には上下方向に直線状に延びた長孔21b,22bが形成されている。
一対の側板21,22の間には2つのバネ受け24,25(復帰機構の一例)が上下方向に移動自在に収納されており、これら2つのバネ受け24,25の間には一個の圧縮コイルバネ26(復帰機構の一例)がバネ受け24,25どうしを上下に離間付勢するように介装されている。尚、各バネ受け24,25は、一対の側板21,22の間に収容されるバネ受け本体24a,25aと、バネ受け本体24a,25aから左右に延びた一対の突起部24b,25bとを含む。一対の突起部24b,25bは、一対の側板21,22の間の空間から長孔21b,22bを通過して更に側板21,22外に突出し、突起部24b,25bの先端は、外部錠ケース11に形成されたスリット状の長孔11a,11b(案内溝の一例、図2と図3を参照のこと)内に係入されている。これらの長孔11a,11bの両端すなわち上下の端部は、各バネ受け24,25の外部錠ケース11に対する移動を所定の範囲内に制限するためのストッパ(復帰機構および係止機構の一例)の役目を果たしている。これらの長孔11a,11bの両端は結果的に圧縮コイルバネ26の各端部を外部錠ケース11に対して係止していることになる。また、バネ受け本体24a,25aには圧縮コイルバネ26の各端部を受け入れるための凹部が設けられている。
そこで、シリンダ錠14が操作されず外力が不在の通常の状況下では、操作スライダ20は、各バネ受け24,25の突起部23b,24bを外部錠ケース11の長孔11a,11bの両端に押付ける圧縮コイルバネ26の付勢力に基づいて、上下方向に関する中間位置に保持される(図4、図10及び図12の状態)。
As shown in FIG. 5, the operation slider 20 is a member obtained by punching and bending a metal plate, and a pair of side plates 21 and 22 that extend in parallel to face each other, and a pair of side plates 21. , 22 are integrally connected to each other. One side plate 21 is formed with a first operation recess 21a for swinging the locking arm 30a via an operated pin 32a, and the other side plate 22 is provided with an unlocking arm 30b via an operated pin 32b. A second operation recess 22a for swinging operation is formed. The side plates 21 and 22 are respectively formed with long holes 21b and 22b extending linearly in the vertical direction.
Two spring receivers 24 and 25 (an example of a return mechanism) are accommodated between the pair of side plates 21 and 22 so as to be movable in the vertical direction. One compression is provided between the two spring receivers 24 and 25. A coil spring 26 (an example of a return mechanism) is interposed so as to urge the spring receivers 24 and 25 apart. Each spring receiver 24, 25 includes a spring receiver main body 24a, 25a accommodated between the pair of side plates 21, 22 and a pair of protrusions 24b, 25b extending left and right from the spring receiver main bodies 24a, 25a. Including. The pair of protrusions 24b and 25b passes through the long holes 21b and 22b from the space between the pair of side plates 21 and 22, and further protrudes outside the side plates 21 and 22, and the ends of the protrusions 24b and 25b are external lock cases. 11 is inserted into slit-shaped long holes 11a and 11b (an example of guide grooves, see FIGS. 2 and 3). Both ends of the long holes 11a and 11b, that is, upper and lower ends are stoppers for restricting movement of the spring receivers 24 and 25 with respect to the external lock case 11 within a predetermined range (an example of a return mechanism and a locking mechanism). It plays the role of These long holes 11a, both ends of the 11b will be that engaging each end of the resulting compressed coil spring 26 against an external lock casing 11. The spring receiving bodies 24a and 25a are provided with recesses for receiving the end portions of the compression coil spring 26.
Therefore, under a normal situation where the cylinder lock 14 is not operated and no external force is present, the operation slider 20 has the projections 23b and 24b of the spring receivers 24 and 25 at both ends of the long holes 11a and 11b of the external lock case 11, respectively. Based on the urging force of the compression coil spring 26 to be pressed, the compression coil spring 26 is held at an intermediate position in the vertical direction (the states of FIGS. 4, 10, and 12).

この操作スライダ20が前記中間位置に位置する状態から、室外にいる者がキーKをシリンダ錠14に挿入して反時計回りに操作すると、ラック板16と操作スライダ20とは、圧縮コイルバネ26の付勢力に抗して上向きに移動操作され、最終的に図7(a)及び図11が示す状態に到達する。すなわち、この時、上方のバネ受け23は長孔11a,11bの上端によって係止されたままで、下方のバネ受け24のみが操作スライダ20の長孔21b,22bの下端部によって上方に押し上げられるため、圧縮コイルバネ26は強制的に押し縮められる。そして、この操作スライダ20の上方への移動(往路操作の一例)に基づいて、施錠アーム30aが操作スライダ20の第1操作凹部21aによって揺動操作され、施錠アーム30aの操作部31aが、外部プレート13の開口部から突出し、後述する内框2側の内部ユニット40のリフタ46を下方に移動操作し、施錠が実行される。この状態から、キーKを時計回りにシリンダ錠14内の中立位置まで戻し操作すると、ラック板16と操作スライダ20とは、圧縮コイルバネ26の付勢力に助けられながら下向きに移動操作され、最終的には、図12に示すように、操作スライダ20は圧縮コイルバネ26の付勢力によって前記中間位置に保持される。この状態ではキーKはシリンダ錠14内の中立位置にあり、抜き取りが可能になる。 When a person outside the room inserts the key K into the cylinder lock 14 and operates it counterclockwise from the state where the operation slider 20 is located at the intermediate position, the rack plate 16 and the operation slider 20 are connected to the compression coil spring 26. It is moved upwardly against the urging force, and finally reaches the state shown in FIGS. That is, at this time, remain above the spring receiver 23 is engaging the upper end of the elongated hole 11a, 11b, only the lower spring receiver 24 is long hole 21b of the operating slider 20, because it is pushed upward by the lower end of 22b The compression coil spring 26 is forcibly compressed. Then, based on the upward movement of the operation slider 20 (an example of an outward operation), the locking arm 30a is swung by the first operation recess 21a of the operation slider 20, and the operation portion 31a of the locking arm 30a is moved to the outside. The plate 13 protrudes from the opening, and a lifter 46 of the inner unit 40 on the inner collar 2 side described later is moved downward to perform locking. From this state, when the key K is rotated clockwise to the neutral position in the cylinder lock 14, the rack plate 16 and the operation slider 20 are moved downward while being assisted by the urging force of the compression coil spring 26. As shown in FIG. 12, the operation slider 20 is held at the intermediate position by the urging force of the compression coil spring 26. In this state, the key K is in the neutral position in the cylinder lock 14 and can be removed.

逆に、この操作スライダ20が前記中間位置に位置する状態から、キーKをシリンダ錠14に挿入して時計回りに操作すると、ラック板16と操作スライダ20とは、圧縮コイルバネ26の付勢力に抗して下向きに移動操作され、最終的に図7(b)及び図13が示す状態に到達する。すなわち、この時、下方のバネ受け22は長孔11a,11bの下端によって係止されたままで、上方のバネ受け23のみが操作スライダ20の長孔21b,22bの上端部によって押し下げられるため、圧縮コイルバネ26は強制的に押し縮められる。そして、この操作スライダ20の下方への移動(復路操作の一例)に基づいて、解錠アーム30bが操作スライダ20の第2操作凹部22aによって揺動操作され、解錠アーム30bの操作部31bが、外部プレート13の開口部から突出し、内部ユニット40のリフタ46を上方に移動操作し、解錠が実行される。この状態から、キーKを反時計回りにシリンダ錠14内の中立位置まで戻し操作すると、ラック板16と操作スライダ20とは、圧縮コイルバネ26の付勢力に助けられながら上向きに移動操作され、最終的には、図4及び図12に示すように、操作スライダ20は圧縮コイルバネ26の付勢力によって前記中間位置に保持される。この状態ではキーKはシリンダ錠14内の中立位置にあり、抜き取りが可能になる。 On the contrary, when the key K is inserted into the cylinder lock 14 and operated clockwise from the state where the operation slider 20 is located at the intermediate position, the rack plate 16 and the operation slider 20 are subjected to the urging force of the compression coil spring 26. On the other hand, it is moved downward and finally reaches the state shown in FIG. 7B and FIG. That is, at this time, remain below the spring receiver 22 is engaging with the elongated holes 11a, 11b the lower end of, for only the upper spring bearing 23 is pushed down by the upper end portion of the long hole 21b, 22b of the operating slider 20, the compression The coil spring 26 is forcibly compressed. Based on the downward movement of the operation slider 20 (an example of the return path operation), the unlocking arm 30b is swung by the second operation recess 22a of the operation slider 20, and the operation unit 31b of the unlocking arm 30b is moved. Then, it protrudes from the opening of the external plate 13 and moves the lifter 46 of the internal unit 40 upward to perform unlocking. From this state, when the key K is returned counterclockwise to the neutral position in the cylinder lock 14, the rack plate 16 and the operation slider 20 are moved upward while being assisted by the urging force of the compression coil spring 26. Specifically, as shown in FIGS. 4 and 12, the operation slider 20 is held at the intermediate position by the urging force of the compression coil spring 26. In this state, the key K is in the neutral position in the cylinder lock 14 and can be removed.

(Configuration of internal unit 40)
As shown in FIGS. 2 and 8, the internal unit 40 includes an internal lock case 41 housed in the cavity of the inner casing 2, and an internal makeup that fixes the inner lock case 41 with the inner casing 2 sandwiched therebetween. A seat 42 and an inner plate 43 are provided. The inner lock case 41 is supported by the striker 33 of the outer casing 1 by swinging around a substantially horizontal axis X1 in accordance with the movement of the slider 44 supported so as to be movable in the vertical direction. A sickle 47 to be removed (an example of a locking member) and a protector 50 that is also displaced laterally in accordance with the movement of the slider 44 are provided. The internal lock case 41 includes a housing-like internal lock case main body 41p and a plate-like internal lock case lid 41q.
A slide knob 45 is fixed to one surface of the slider 44, and a lifter 46 is fixed to the other surface. The slide knob 45 protrudes from an opening 42 a provided in the internal decorative seat 42, and a person in the room can operate the slider 44 up and down by operating the slide knob 45. Further, the locking arm 30a or the unlocking arm 30b of the external unit 10 can operate the slider 44 up and down by pushing down the lifter 46 or pushing it up.

鎌47は、鎌47の軸芯X1に向かって延びた長孔47bを備えており、内部錠ケース41にも概して上下方向に延びた長孔41aが形成されている。鎌47の長孔47bと内部錠ケース41の長孔41aには、共通の***作ピン48が挿通されている。そして、摺動子44には***作ピン48と接当する操作部44aが設けられている。また、鎌47には***作ピン48を長孔47bの端部に押付ける捻りコイルばね49が設けられている。摺動子44が上死点に位置する時には、鎌47は捻りコイルばね49の付勢力によって図2、図9(a)及び図10に示す解錠姿勢に保持されている。摺動子44が下死点に向けて移動操作されると、摺動子44の操作部44aが***作ピン48を内部錠ケース41の長孔41aに沿って押し下げる結果、鎌47は軸芯X1周りで揺動し、図9(b)及び図11に示す施錠姿勢に切り換えられ、引き続き捻りコイルばね49の付勢力によって施錠姿勢に保持される。施錠姿勢では、鎌47のフック部47aが内部プレート43の第1開口部43aを通過して外框1のストライク部33に係合する。   The sickle 47 includes a long hole 47b extending toward the axis X1 of the sickle 47, and the inner lock case 41 is also formed with a long hole 41a extending generally in the vertical direction. A common operated pin 48 is inserted into the long hole 47 b of the sickle 47 and the long hole 41 a of the internal lock case 41. The slider 44 is provided with an operation portion 44 a that contacts the operated pin 48. The sickle 47 is provided with a torsion coil spring 49 that presses the operated pin 48 against the end of the long hole 47b. When the slider 44 is located at the top dead center, the sickle 47 is held in the unlocked posture shown in FIGS. 2, 9 (a) and 10 by the biasing force of the torsion coil spring 49. When the slider 44 is moved toward the bottom dead center, the operation portion 44a of the slider 44 pushes down the operated pin 48 along the long hole 41a of the internal lock case 41. It swings around X1 and is switched to the locking posture shown in FIGS. 9B and 11, and is continuously held in the locking posture by the urging force of the torsion coil spring 49. In the locking posture, the hook portion 47 a of the sickle 47 passes through the first opening 43 a of the inner plate 43 and engages with the strike portion 33 of the outer casing 1.

プロテクタ50は、内部プレート43の第2開口部43b内に前後方向に移動自在に受け入れられている。また、プロテクタ50の一方の側面の上下2箇所には第1***作ピン50a,50bが設けられており、プロテクタ50の他方の側面には第2***作ピン50cが設けられている。また、摺動子44には、プロテクタ50の第1***作ピン50a,50bと接当する傾斜カム面44b,44cと、プロテクタ50の第2***作ピン50cを受け入れる傾斜した長孔44dとが形成されている。摺動子44が上死点に位置する時には、プロテクタ50は図9(a)及び図10に示す退避姿勢に保持されている。摺動子44が下死点に向けて移動操作されると、摺動子44の傾斜カム面44b,44cがプロテクタ50の第1***作ピン50a,50bを外框1向きに押出す結果、プロテクタ50は、図9(b)及び図11に示す突出姿勢に切り換えられ、室外側引戸Aと室内側引戸Bの間の間隙からリフタ46を押し上げ操作しようと試みる進入者から防御する。この状態から、再び摺動子44が上死点に向けて移動操作されると、摺動子44の長孔44dの外框1側の縁部がプロテクタ50の第2***作ピン50cを内部化粧座42向きに押し戻す結果、プロテクタ50は再び図9(a)及び図10に示す退避姿勢に復帰操作される。   The protector 50 is received in the second opening 43b of the inner plate 43 so as to be movable in the front-rear direction. Further, first operated pins 50 a and 50 b are provided at two locations on one side of the protector 50, and a second operated pin 50 c is provided on the other side of the protector 50. Further, the slider 44 has inclined cam surfaces 44b and 44c that contact the first operated pins 50a and 50b of the protector 50, and an inclined long hole 44d that receives the second operated pin 50c of the protector 50. Is formed. When the slider 44 is located at the top dead center, the protector 50 is held in the retracted posture shown in FIGS. When the slider 44 is moved toward the bottom dead center, the inclined cam surfaces 44b and 44c of the slider 44 push the first operated pins 50a and 50b of the protector 50 toward the outer casing 1, The protector 50 is switched to the protruding posture shown in FIG. 9B and FIG. 11, and protects against an intruder who tries to push up the lifter 46 from the gap between the outdoor sliding door A and the indoor sliding door B. From this state, when the slider 44 is moved again toward the top dead center, the edge of the elongated hole 44d of the slider 44 on the outer flange 1 side inserts the second operated pin 50c of the protector 50 inside. As a result of pushing back toward the decorative seat 42, the protector 50 is again returned to the retracted position shown in FIGS. 9A and 10.

(施錠と解錠の操作について)
図2及び図10は、室外側引戸Aと室内側引戸Bを閉じ合わせた、すなわち外框1と内框2とが互いに対向した状態を示す。この状態では、外部ユニット10の施錠アーム30aと解錠アーム30b、及び、内部ユニット40の鎌47とプロテクタ50は、いずれも退避姿勢にある。この状態から、室外に居る者がキーKをシリンダ錠14に挿入して反時計回りに操作すると、ラック板16と操作スライダ20とが、圧縮コイルバネ26の付勢力に抗して上向きに移動操作され、施錠アーム30aが操作スライダ20の第1操作凹部21aによって揺動操作され、施錠アーム30aの操作部31aが、外部プレート13の開口部から突出して、内部ユニット40のリフタ46と摺動子44を下方に移動操作するので、図11に示すように、鎌47が揺動操作されてストライク部33に係合することで施錠が実行される。同時にプロテクタ50も突出姿勢に切り換えられる。この状態から、キーKを時計回りにシリンダ錠14内の中立位置まで戻し操作すると、図12に示すように、ラック板16と操作スライダ20とは、圧縮コイルバネ26の付勢力に助けられながら下向きに移動操作され、施錠アーム30aは操作スライダ20によって退避姿勢に戻され、最終的に操作スライダ20は圧縮コイルバネ26の付勢力によって前記中間位置に保持される。この状態では、キーKはシリンダ錠14内の中立位置にあり、キーKの抜き取りが可能になる。鎌47は施錠状態であり、プロテクタ50も突出姿勢を維持している。
尚、室内に居る者がスライド摘み45を下方に移動操作した場合も、同様にラック板16と操作スライダ20とが移動操作されるが、この場合は、施錠アーム30aの操作を介することなく最終的に鎌47が揺動操作されて施錠が実行される。
(About operation of locking and unlocking)
2 and 10 show a state in which the outdoor sliding door A and the indoor sliding door B are closed, that is, the outer casing 1 and the inner casing 2 face each other. In this state, the locking arm 30a and the unlocking arm 30b of the external unit 10 and the sickle 47 and the protector 50 of the internal unit 40 are all in the retracted posture. From this state, when a person outside the room inserts the key K into the cylinder lock 14 and operates it counterclockwise, the rack plate 16 and the operation slider 20 are moved upward against the urging force of the compression coil spring 26. Then, the locking arm 30a is swung by the first operation recess 21a of the operation slider 20, and the operation portion 31a of the locking arm 30a protrudes from the opening of the external plate 13, and the lifter 46 and the slider of the internal unit 40 Since 44 is moved downward, as shown in FIG. 11, the sickle 47 is swung and engaged with the strike portion 33 to perform locking. At the same time, the protector 50 is also switched to the protruding posture. From this state, when the key K is operated to return clockwise to the neutral position in the cylinder lock 14, the rack plate 16 and the operation slider 20 face downward while being assisted by the urging force of the compression coil spring 26, as shown in FIG. The locking arm 30 a is returned to the retracted position by the operation slider 20, and finally the operation slider 20 is held at the intermediate position by the urging force of the compression coil spring 26. In this state, the key K is in the neutral position in the cylinder lock 14, and the key K can be removed. The sickle 47 is in a locked state, and the protector 50 also maintains the protruding posture.
In addition, when a person in the room moves the slide knob 45 downward, the rack plate 16 and the operation slider 20 are similarly moved. In this case, the final operation is performed without operating the locking arm 30a. Thus, the sickle 47 is swung to perform locking.

逆に、図12に示す鎌47による施錠がなされている状態から、室外に居る者がキーKをシリンダ錠14に挿入して時計回りに操作すると、ラック板16と操作スライダ20とは、圧縮コイルバネ26の付勢力に抗して下向きに移動操作され、解錠アーム30bが操作スライダ20の第2操作凹部22aによって揺動操作され、解錠アーム30bの操作部31bが、外部プレート13の開口部から突出し、内部ユニット40のリフタ46と摺動子44を上方に移動操作するので、図13に示すように、鎌47が逆向きに揺動操作されてストライク部33から係合解除されることで解錠が実行され、同時に、プロテクタ50も退避姿勢に戻される。この状態から、キーKを反時計回りにシリンダ錠14内の中立位置まで戻し操作すると、図10に示すように、ラック板16と操作スライダ20とは、圧縮コイルバネ26の付勢力に助けられながら上向きに移動操作され、解錠アーム30bは操作スライダ20によって退避姿勢に戻され、最終的に操作スライダ20は圧縮コイルバネ26の付勢力によって前記中間位置に保持される。この状態ではキーKはシリンダ錠14内の中立位置にあり、抜き取りが可能になる。
尚、室内に居る者がスライド摘み45を上方に移動操作した場合も、同様にラック板16と操作スライダ20とが移動操作されるが、この場合は、解錠アーム30bの操作を介することなく最終的に鎌47が揺動操作されて解錠が実行される。
Conversely, when the person outside the room inserts the key K into the cylinder lock 14 and operates clockwise from the state where the sickle 47 is locked as shown in FIG. 12, the rack plate 16 and the operation slider 20 are compressed. The unlocking arm 30 b is operated to move downward by the second operation recess 22 a of the operation slider 20, and the operation portion 31 b of the unlocking arm 30 b is opened to the outer plate 13. Since the lifter 46 and the slider 44 of the internal unit 40 are moved upward, the sickle 47 is swung in the reverse direction to be disengaged from the strike portion 33, as shown in FIG. Thus, unlocking is executed, and at the same time, the protector 50 is also returned to the retracted posture. From this state, when the key K is returned counterclockwise to the neutral position in the cylinder lock 14, the rack plate 16 and the operation slider 20 are assisted by the urging force of the compression coil spring 26 as shown in FIG. The unlocking arm 30b is returned to the retracted position by the operation slider 20, and finally the operation slider 20 is held at the intermediate position by the urging force of the compression coil spring 26. In this state, the key K is in the neutral position in the cylinder lock 14 and can be removed.
Note that when the person in the room moves the slide knob 45 upward, the rack plate 16 and the operation slider 20 are similarly moved. In this case, the operation is not performed via the unlocking arm 30b. Finally, the sickle 47 is swung to unlock the sickle.

(外部ユニット10の組立て工程について)
当該引違戸錠100では、特に外部ユニット10の復帰機構の組立て性が改善されている。外部ユニット10の組立て時には、図5に示すように、先ず、操作スライダ20の中に2個のバネ受け24,25を、バネ受け24,25の突起部24b,25bが長孔21b,22bから突出するように嵌め込み、次に、圧縮コイルバネ26をバネ受け24,25どうしを上下に離間付勢するように介装すれば、上下のバネ受け24,25の各突起部24b,25bが、圧縮コイルバネ26によって長孔21b,22bの両端に押付けられた状態となり、復帰機構としての役目を果たすサブアセンブリが完成する(図6を参照)。その後は、図6に示すように、操作スライダ20の側板21,22の間に、施錠アーム30aと解錠アーム30bを退避姿勢となるように収納し、次に、図3及び図10に示すように、そのまま操作スライダ20を、既にスライダーガイド27とピニオン15とが取り付けられた外部錠ケース本体11pに対して、外部錠ケース本体11pに立設されたアームピン11sが施錠アーム30aと解錠アーム30bの貫通孔30hに挿通されるように、且つ、操作スライダ20の側板21外に突出している突起部24bが外部錠ケース本体11pの長孔11a内に係入されるように嵌め込み、次に、ラック板16のラック部をピニオン15と噛合させ、ラック板16の上端を操作スライダ20の係入孔に係止し、最後に、外部錠ケース蓋体11qを、側板22外に突出している突起部25bが外部錠ケース蓋体11qの長孔11b内に係入されるように合わせて、外部錠ケース本体11pに対して固定すれば外部ユニット10の組立てが完了する。
(About the assembly process of the external unit 10)
In the sliding door lock 100, in particular, the assemblability of the return mechanism of the external unit 10 is improved. When the external unit 10 is assembled, as shown in FIG. 5, first, the two spring receivers 24 and 25 are inserted into the operation slider 20, and the protrusions 24b and 25b of the spring receivers 24 and 25 are inserted into the long holes 21b and 22b. When the compression spring 26 is inserted so as to protrude and then the compression coil spring 26 is interposed so as to urge the spring receivers 24 and 25 apart from each other, the projections 24b and 25b of the upper and lower spring receivers 24 and 25 are compressed. The coil assembly 26 is pressed against both ends of the long holes 21b and 22b, thereby completing a subassembly that serves as a return mechanism (see FIG. 6). Thereafter, as shown in FIG. 6, the locking arm 30a and the unlocking arm 30b are retracted between the side plates 21 and 22 of the operation slider 20 and then shown in FIGS. 3 and 10. As described above, the operation pin 20 is directly connected to the external lock case main body 11p to which the slider guide 27 and the pinion 15 are already attached. The arm pin 11s erected on the external lock case main body 11p has the lock arm 30a and the unlock arm. The protrusion 24b protruding from the side plate 21 of the operation slider 20 is inserted into the long hole 11a of the external lock case body 11p so as to be inserted into the through hole 30h of the operation slider 20, and then fitted. The rack portion of the rack plate 16 is engaged with the pinion 15, the upper end of the rack plate 16 is locked in the engagement hole of the operation slider 20, and finally, the outer lock case lid 11q. The external unit 10 can be assembled by fixing the protrusion 25b protruding outside the side plate 22 to be engaged with the long hole 11b of the external lock case lid 11q and fixing it to the external lock case body 11p.
