Description

本発明は、本発明は、デッドボルトに対する側圧対策用のダブル施錠の錠前に関する。 The present invention relates to a lock of a double lock for a countermeasure against a side pressure against a dead bolt.

特許文献１〜特許文献４は、錠箱から突出するデッドボルトの側圧対策関するものである。特許文献１の請求項４には、扉や扉枠の側圧がラッチ本体の背面にかかった時に、デッドボルトに側圧がかからないようにラッチ本体の厚みをデッドボルトの厚みよりも大きく設定する事項が記載されている。 Patent Documents 1 to 4 relate to measures against a side pressure of a dead bolt protruding from a lock box. In claim 4 of Patent Document 1, when the side pressure of the door or door frame is applied to the back surface of the latch body, there is a matter of setting the thickness of the latch body larger than the thickness of the dead bolt so that the side pressure is not applied to the dead bolt. Are listed.

また、特許文献２には、デッドボルトを兼ねるラッチアセンブリーを有する錠箱において、閉扉時、ラッチアセンブリーにかかる側圧に対する強度を向上させる事項が記載されている。 Japanese Patent Application Laid-Open No. H10-228561 describes a matter of improving the strength against side pressure applied to the latch assembly when the door is closed in a lock box having a latch assembly that also serves as a dead bolt.

また、特許文献３には、デッドボルトに交差した側圧力が錠箱のデッド窓の縁辺に集中的にかかるのを防止することができる錠前用デッドボルトの構造が記載されている。 Patent Document 3 describes a structure of a lock dead bolt that can prevent the side pressure crossing the dead bolt from being concentrated on the edge of the dead window of the lock box.

さらに、特許文献４には、室外側からデッドボルトに強度の側圧力がかかったとしても、ケース身のデッド窓を形成する縁部が容易に裂けない（縁部が強靭な）戸の錠箱の構造が記載されている。 Furthermore, Patent Document 4 discloses a door lock box in which the edge forming the dead window of the case body is not easily torn (the edge is strong) even when a strong side pressure is applied to the dead bolt from the outside. The structure of is described.

上記のように、従来、デッドボルトに対する扉や扉枠の側圧を軽減化する構造が色々と試みられているが、特に、ダブル施錠の錠前（電気錠も含む）に於いて、デッドボルトに対する扉や扉枠の側圧を軽減化する新規な構成が要望されている。 As described above, various attempts have been made to reduce the lateral pressure of the door and door frame against the dead bolt as described above. In particular, the door to the dead bolt in the double lock (including the electric lock). There is a demand for a new configuration that reduces the side pressure of the door frame.

一方、特許文献５や特許文献６には、ドアを閉鎖した際にドア側のラッチ（仮施錠片）を受けるようにした受け具において、戸当りとドアとの間にすき間が出来ないようにする調節が可能で、しかもドアに開き方向の大きな力が加わっても、調節した状態を堅く保持できる受け具が提案されている。このラッチ用受け具の基本的構成は、トロヨケと称されるケースと、ストライクと称されるカバー状基板と、前記ケースに調整可能に内装され、かつ、ラッチの係合面に対する受止面を有するスライドボックスと、このスライドボックスの底面及び前記ケースの底面に亘って設けられた多角形の回動式調節板とから成る。 On the other hand, in Patent Document 5 and Patent Document 6, in a receiving device that receives a latch (temporary locking piece) on the door side when the door is closed, there is no gap between the door stop and the door. There has been proposed a receiver that can be adjusted and can hold the adjusted state firmly even when a large force is applied to the door in the opening direction. The basic structure of the latch receiving device is as follows: a case called Troyoke, a cover-like substrate called a strike, an adjustably built in the case, and a receiving surface with respect to the engaging surface of the latch. And a polygonal rotary adjustment plate provided over the bottom surface of the slide box and the bottom surface of the case.

一方、特許文献７の図５及び図６には、ドアを閉鎖した際にドア側のデッドボルト（本施錠片）を受けるようにした受け具において、戸当りとドアとの間にすき間が出来ないようにするために、「ケース内に受止面を有するスライドボックスを内装し、スライドボックスの一側外面とケースの対向内面との隙間に板材を切断して交差状に形成した板ばねを配設する事項」が記載されている。 On the other hand, in FIG. 5 and FIG. 6 of Patent Document 7, there is a gap between the door stop and the door in the receiving device that receives the door-side dead bolt (this locking piece) when the door is closed. In order to prevent the occurrence of a plate spring, a slide box having a receiving surface inside the case and a plate spring formed in a cross shape by cutting a plate material in the gap between the outer surface on one side of the slide box and the inner surface facing the case Items to be arranged ”are described.

特許文献５乃至特許文献７に記載の各実施例のように、従来は、仮施錠片であれ、本施錠片であれ、扉の閉鎖時におけるガタツキを防止するために、「トロヨケ内にスライドボックスを設けると共に調整手段を適宜に配設し、施錠片の垂直係合面（側面）が該スライドボックスの受止部に接触するように構成」している。 As in each of the embodiments described in Patent Document 5 to Patent Document 7, conventionally, in order to prevent rattling when the door is closed, whether the temporary locking piece or the present locking piece, a “slide box in the trolley” is used. And an adjusting means are provided as appropriate so that the vertical engagement surface (side surface) of the locking piece is in contact with the receiving portion of the slide box.

したがって、従来の実施例は、受け具の構成が複雑となる、戸当りとドアとの間にすき間が出来ないようにスライドボックスの位置や大きさを、調整手段を介して適宜に設定する必要性がある、といったような問題点を有していた。 Therefore, in the conventional embodiment, the configuration of the receiving device is complicated, and the position and size of the slide box must be appropriately set via the adjusting means so that there is no gap between the door stop and the door. There was a problem such as that.

扉のガタツキ防止に関して、ダブル施錠の錠前（電気錠も含む）に於いても、デッドボルトに対する側圧対策と同時に、扉のガタツキ防止を図ることが要望されている。

It is a dead bolt that moves forward and backward from the lock box by the driving force of the inner dharma. On the other hand, the smaller second locking piece 12 has a protruding input piece 11 fixed to the inner end of the first locking piece 6. with protruding from the lock box 1 during locking through the in order to reduce the lateral pressure exerted on the dead bolt, the said deadbolt a lateral pressure receiving piece provided separately, moreover, the second locking piece 12 , when the dead bolt when unlocking is retracted into the lock box, characterized in that retraction said pulled back engagement portion provided on the projecting end of the projecting input portion 11 into the lock box.

また、本発明の扉のダブル施錠の錠前は、錠箱に大小２個の施錠片を上下方向に所定間隔を有して配設し、大きい方の第１施錠片は、錠箱内のダルマの駆動力により進退動するデッドボルトであり、一方、小さい方の第２施錠片は、前記第１施錠片の内端部に固定した突出入力片を介して錠箱から突出する側圧受け片であり、この第２施錠片は、解錠時、デッドボルトが錠箱内に後退すると、錠箱内に配設した付勢手段によって引き戻される可動部材を介して錠箱内に引っ込むことを特徴とする。 In addition, the double lock of the door of the present invention has a lock box in which two large and small lock pieces are arranged at predetermined intervals in the vertical direction, and the larger first lock piece is a Dharma in the lock box. On the other hand, the smaller second locking piece is a side pressure receiving piece that protrudes from the lock box via a protruding input piece fixed to the inner end of the first locking piece. The second locking piece is characterized in that when unlocked, when the dead bolt is retracted into the lock box, the second lock piece is retracted into the lock box via a movable member that is pulled back by the urging means disposed in the lock box. To do.

（ａ）例えば図１１で示すように、メインの第１施錠片（デッドボルト）が錠箱内に後退してから、サブの第２施錠片（側圧受け片）が第１施錠片により錠箱内に引き戻され、或いは付勢手段により自動的に後退するので、デッドボルトが後退中に、開扉動作に起因する側圧がデッドボルトに極力かからないようにすることができる。したがって、ダブル施錠の錠前（電気錠も含む）に於いて、デッドボルトに対する側圧対策を図ることができる。
（ｂ）第２施錠片やストッパーと共にユニット化された可動部材を錠箱に内に簡単に組み込むことができる。
（ｃ）第２施錠片の進退動をスムースに促す（案内する）ことができる。
（ｄ）その他、例えば図３、図４及び図８、図９で示すように、複数の施錠状態を得ることができるので、側圧対策のみならず、扉のガタツキ対策の効果も同時に得ることができる。付言すると、本発明は、シンプルな受け具の使用が可能であり、しかも、受け具側でスライドボックスの位置調整をしなくても、例えば建具の施工時に生ずる受け具と建具との位置誤差、或いは室内外の温度差に起因する扉の一時的変形（反り）によって発生する戸当りとドアとのガタツキを、戸枠側の受け具に対する扉側の錠前に設けたガタツキ防止機能を有する第２施錠片によって解消することができる。 (A) For example, as shown in FIG. 11, after the main first locking piece (dead bolt) is retracted into the lock box, the sub second locking piece (side pressure receiving piece) is locked by the first locking piece. Since it is pulled back in or automatically retracted by the urging means, it is possible to prevent the side pressure caused by the opening operation from being applied to the dead bolt as much as possible while the dead bolt is retracting. Therefore, in the double lock lock (including the electric lock), it is possible to take a countermeasure against the side pressure against the dead bolt.

(C) The second locking piece can be smoothly urged (guided) to advance and retreat.
(D) In addition, as shown in FIG. 3, FIG. 4, FIG. 8, and FIG. 9, for example, a plurality of locked states can be obtained. it can. In addition, the present invention can use a simple receiver, and without adjusting the position of the slide box on the receiver side, for example, a positional error between the receiver and the joiner that occurs during construction of the joiner, Alternatively, a second function having a backlash prevention function in which the backlash between the door stop and the door caused by the temporary deformation (warping) of the door due to a temperature difference between the inside and outside of the room is provided at the door side lock against the door frame side holder. It can be solved by a locking piece.

以下、図１乃至図１６に示す本発明の最良の一例を「電気錠」に適用して説明する。 The best example of the present invention shown in FIGS. 1 to 16 will be described below by applying it to an “electric lock”.

（１）発明の実施の環境
図１は本発明の主要部を含む電気錠の概念図である。まず、図１及び図２を参照にして、電気錠の主な構成部材と作動態様の流れを簡単に説明する。電気錠Ｘは、錠箱１内に制御部２、駆動モータ３、クラッチ機構を含む動力伝達手段４、ダルマ５、デッドボルト６等が設けられている。なお、図２では、制御部２、駆動モータ３、クラッチ機構を含む動力伝達手段４等の具体的構成は、本発明の特定要件ではないので、割愛している。 (1) Environment for Implementing the Invention FIG. 1 is a conceptual diagram of an electric lock including the main part of the present invention. First, with reference to FIG.1 and FIG.2, the main components of an electric lock and the flow of an operation | movement aspect are demonstrated easily. The electric lock X is provided with a control unit 2, a drive motor 3, a power transmission means 4 including a clutch mechanism, a dharma 5, a dead bolt 6, and the like in the lock box 1. In FIG. 2, the specific configuration of the control unit 2, the drive motor 3, the power transmission means 4 including the clutch mechanism, and the like is not a specific requirement of the present invention and is omitted.

周知のように、デッドボルト６は、駆動モータ３の駆動力により、錠箱１のフロント７を基準にして戸枠側の受け具８へと前進する。施錠時、錠箱１のフロント７から突出した第１施錠片（デッドボルト）６は受け具８に係合し、一方、扉Ｄを開く際の解錠時、デッドボルト６は錠箱１内へと後退し始め、完全解錠時には、デッドボルト６の先端面は、フロント７の外面に位置する。 As is well known, the dead bolt 6 is moved forward to the door frame side receiving tool 8 with reference to the front 7 of the lock box 1 by the driving force of the driving motor 3. At the time of locking, the first locking piece (dead bolt) 6 protruding from the front 7 of the lock box 1 is engaged with the receiving device 8, while when unlocking when the door D is opened, the dead bolt 6 is inside the lock box 1. The tip end surface of the dead bolt 6 is located on the outer surface of the front 7 at the time of complete unlocking.

ところで、後述する受け具の中心線の位置に対して、錠前を含む建具（扉）の取付け位置の誤差、或いは室内外の温度差により扉が反ると、錠前の錠箱の位置が室内又は室外へずれることになる。そのために、受け具側の受止部と第２施錠片（サブの施錠片）の係合面との間に隙間が生じることから、戸当りとドアとの間にすき間ができ、その結果、扉がガタツク。 By the way, if the door is warped due to an error in the attachment position of the fitting (door) including the lock or a temperature difference between the interior and the exterior with respect to the position of the center line of the receiver described later, the position of the lock box in the lock is indoor or It will slip out of the room. Therefore, a gap is generated between the receiving part on the receiving side and the engaging surface of the second locking piece (sub-locking piece), so that there is a gap between the door stop and the door. The door is rattling.

そこで、本実施例の電気錠Ｘは、例えば受け具側でスライドボックスの位置調整をしなくても、例えば施工時における建具の取付け位置の誤差、或いは室内外の温度差に起因する扉の一時的変形（反り）によって発生する戸当りとドアとのガタツキを、戸枠側の受け具８に対する扉側の錠前Ｘに設けた側圧対策・ガタツキ対策用可動部材Ｙによって解消する。 Therefore, the electric lock X according to the present embodiment can be used, for example, without the adjustment of the position of the slide box on the receiving side, for example, the error of the attachment position of the fitting at the time of construction, or the temporary door due to the temperature difference between the indoor and the outdoor. The looseness between the door contact and the door, which is caused by a general deformation (warp), is eliminated by a side pressure countermeasure / rattle prevention movable member Y provided in the lock X on the door side with respect to the door-side receiving member 8.

すなわち、ユニット化された可動部材Ｙには、第１施錠片（メインの施錠片）６にかかる側圧を防止或いは軽減化すると共に、扉のガタツキを防止する機能も有する第２施錠片（サブの施錠片）１２が、メインの施錠片（デッドボルト）６の下方に併設的に配設されている。 That is, the unitized movable member Y has a second locking piece (sub-locking) having a function of preventing or reducing the side pressure applied to the first locking piece (main locking piece) 6 and also preventing the backlash of the door. A locking piece) 12 is disposed side by side below the main locking piece (dead bolt) 6.

可動部材Ｙは、施錠時、デッドボルト６に固定的に設けた突出入力片１１を介して押し出され、その結果、可動部材２１の前側に位置する第２施錠片１２は、フロント７から突出して受け金具８に係合する。そして、本実施例では、さらに、側圧対策・ガタツキ対策用可動部材Ｙに軸支されたストッパー４１，４１Ａは、施工時における建具の取付け位置の誤差、或いは室内外の温度差に起因する扉の一時的変形（反り）如何により、ガタツキ防止部材１２に対する係合（施錠）位置が変わる。 At the time of locking, the movable member Y is pushed out through a protruding input piece 11 fixedly provided on the dead bolt 6, and as a result, the second locking piece 12 positioned on the front side of the movable member 21 protrudes from the front 7. Engage with the catch 8. In the present embodiment, the stoppers 41 and 41A that are pivotally supported by the movable member Y for countermeasures against side pressure and backlash are the error in the attachment position of the fitting at the time of construction or the temperature difference between the indoor and the outdoor. Depending on the temporary deformation (warping), the engagement (locking) position with respect to the rattling prevention member 12 changes.

一方、解錠時、ストッパー４１，４１Ａは、デッドボルト６の後退を条件として第２施錠片１２の動きを許容する。本実施例では、前述したストッパーは、錠箱側の係止手段５１に係合する第２被係合部を有し、この第２被係合部は、閉扉時、錠箱に直接又は間接的に設けた係止手段５１の係止端面５１ｂに係止される反面、デッドボルト６が後退した時には、入力片１１を介して前記係止端面から離れ、その後に、第２施錠片１２を備える可動部材Ｙは、錠箱内に設けた可動部材戻し用の付勢手段４９のバネ力により後退する。 On the other hand, at the time of unlocking, the stoppers 41 and 41A allow the movement of the second locking piece 12 on condition that the dead bolt 6 is retracted. In this embodiment, the stopper described above has a second engaged portion that engages with the locking means 51 on the lock box side, and this second engaged portion is directly or indirectly on the lock box when the door is closed. On the other hand, when the dead bolt 6 is retracted, it is separated from the locking end surface via the input piece 11, and then the second locking piece 12 is moved to the second locking piece 12. The movable member Y provided is retracted by the spring force of the urging means 49 for returning the movable member provided in the lock box.

（２）入力片１１
まず、図３は施錠時におけるデッドボルト６と第２施錠片１２の突出状態等を示す概略説明図である。この図３を説明の便宜上「正面側」とする。図４は図３を基準とする「底面側」からの概略説明図である。図４は底面側からの説明図であるから、ここでは符号１２ａは手前の見える第１ガタツキ防止部材とし、一方、符号１２ｂは向こう側に見える第２ガタツキ防止部材とする。 (2) Input piece 11
First, FIG. 3 is a schematic explanatory view showing the protruding state of the dead bolt 6 and the second locking piece 12 during locking. 3 is referred to as “front side” for convenience of explanation. FIG. 4 is a schematic explanatory view from the “bottom side” with reference to FIG. Since FIG. 4 is an explanatory view from the bottom side, reference numeral 12a is a first anti-rattle member that can be seen in front, while reference numeral 12b is a second anti-rattle member that is visible on the other side.

したがって、図４では第１ガタツキ防止部材１２ａと第２ガタツキ防止部材１２ｂの突出外端部の各下面が交差状に見えている。図３で示すように、本実施例の第２施錠片１２は、進退動可能な可動部材（可動ヘース板２１、ホルダー３１等）Ｙを介して上下方向に重ねるように二枚配設され、これら二枚の第２施錠片（ガタツキ防止部材）１２ａ、１２ｂの突出外端部の角度は、鋏揺動自在に変わる。 Therefore, in FIG. 4, the lower surfaces of the protruding outer end portions of the first rattling prevention member 12 a and the second rattle prevention member 12 b appear to intersect. As shown in FIG. 3, the second locking pieces 12 of the present embodiment are arranged so as to be vertically stacked via movable members (movable hose plate 21, holder 31, etc.) Y that can move forward and backward, The angles of the projecting outer ends of the two second locking pieces (rattle prevention members) 12a and 12b change so as to freely swing.

次に、図６の（ａ）は入力片１１の正面図、（ｂ）はその斜視図である。入力片１１は、その上端部１１ａは複数個の不番の固定具を介してデッドボルト６の側壁６ａの中央部に固定され、一方、中央部１１ｂの折り曲げ部分に連設する突出端部（下端部）１１ｃは、デッドボルト６の下面（側壁の一つ）から垂直状態に突出している。 6A is a front view of the input piece 11, and FIG. 6B is a perspective view thereof. The input piece 11 has an upper end portion 11a fixed to the central portion of the side wall 6a of the dead bolt 6 through a plurality of unfixed fasteners, and on the other hand, a projecting end portion continuously provided to the bent portion of the central portion 11b ( The lower end 11c protrudes vertically from the lower surface (one of the side walls) of the dead bolt 6.

しかして、前記突出端部１１ｃの幅広端部の左右部位（先端部と後端部）には、折り曲げて形成された合計２個の押圧式入力部（係合部）１３，１４が設けられている。ここでは、図６の（ａ）を基準にして、左側の符号１３を前入力部（ストッパー解錠用）とし、一方、右側の符号１４を後入力部（施錠状態移行用）とする。 Thus, a total of two press-type input portions (engaging portions) 13 and 14 formed by bending are provided at the left and right portions (front end portion and rear end portion) of the wide end portion of the protruding end portion 11c. ing. Here, on the basis of FIG. 6A, the left reference numeral 13 is a front input part (for stopper unlocking), while the right reference numeral 14 is a rear input part (for locking state transition).

前記前入力部１３は、解錠時或いは解錠の途中に、デッドボルト６が「所定の後退条件」を満たしたときに上側に位置するストッパー（実施例では第１のストッパー４１）の第１被係合部４４に係合して、該第２被係合部４６ａを錠箱１に設けた係止手段５１の係止端面５１ｂ（後述）から離す。一方、前記後入力部１４は、施錠時、ストッパー４１の第１被係合部４４或いは可動部材（可動ベース板）２１の係合突起に係合（本実施例）して、可動部材Ｙをフロント７側へと押し出す。その結果、第２施錠片１２がフロント７から突出する。 The front input unit 13 is a first stopper of a stopper (first stopper 41 in the embodiment) located on the upper side when the dead bolt 6 satisfies the “predetermined retraction condition” at the time of unlocking or in the middle of unlocking. By engaging with the engaged portion 44, the second engaged portion 46 a is separated from the locking end surface 51 b (described later) of the locking means 51 provided in the lock box 1. On the other hand, the rear input unit 14 engages with the engagement protrusions of the first engaged portion 44 of the stopper 41 or the movable member (movable base plate) 21 at the time of locking (this embodiment), and moves the movable member Y. Push out to the front 7 side. As a result, the second locking piece 12 protrudes from the front 7.

The projecting outer end of the piece 12 hits the receiving surfaces 8a, 8b of the receiving device 8 A plurality of biasing means 15 that constantly bias in the direction are provided.

そして、前記第２施錠片１２は、前記受け具８の中心線Ｏの位置に対して、例えば建具施工時の取付け位置の誤差、或いは建具の取付け位置の誤差がなくても一時的な扉の反りによって前記錠箱１が室内ＩＮ又は室外ＯＵＴへずれ、かつ、受け具８の受止面８ａ、８ｂで突出外端部が押圧され得る状態になった場合に前記付勢手段１５のバネ力に抗して回転し、第２施錠片１２の被係合部分１９ａ、１９ｂに対するストッパー４１，４１Ａの係合位置（第２実施例）が、又はストッパー４１，４１Ａの係合部分４５に対する第２施錠片１２の被係合部分１９ａ、１９ｂの係合位置（第１実施例）が変わる。 Then, the second locking piece 12 can be used as a temporary door even if there is no error in the attachment position of the fitting or the attachment position of the fitting with respect to the position of the center line O of the receiver 8. The spring force of the biasing means 15 when the lock box 1 is displaced to the indoor IN or the outdoor OUT due to warping and the protruding outer end portion can be pressed by the receiving surfaces 8a and 8b of the receiving device 8. The second position of the stoppers 41 and 41A with respect to the engaging portions 45 of the stoppers 41 and 41A is the second position of the stoppers 41 and 41A. The engaging positions (first embodiment) of the engaged portions 19a and 19b of the locking piece 12 are changed.

（４）第２施錠片１２
第２施錠片１２は、側圧対策機能とガタツキ対策機能の両方を有している。図７の（ａ）、（ｂ）、（ｃ）は、第２施錠片１２の一例（例えば第１ガタツキ防止部材１２ａ）を示す各概略説明図である。なお、第２ガタツキ防止部材も同一構成なので、第１ガタツキ防止部材１２ａの説明を援用する。 (4) Second locking piece 12
The second locking piece 12 has both a lateral pressure countermeasure function and a backlash countermeasure function. (A), (b), (c) of FIG. 7 is each schematic explanatory drawing which shows an example (for example, 1st rattling prevention member 12a) of the 2nd locking piece 12. FIG. In addition, since the 2nd rattle prevention member is also the same structure, description of the 1st rattle prevention member 12a is used.

さて、図７の（ａ）は、第１ガタツキ防止部材１２ａの一側外面（下面）１６が見えるように示した斜視図、また、図７の（ｂ）は、Ａ矢印（下面）側から見た説明図、さらに、図７の（ｃ）は、Ｂ矢印（内端面）側から見た説明図である。したがって、図７の（ｃ）を基準にすると、符号１６は一側下面、符号１７は一側上面ということになる。
図７に於いて、１８は半柱状中央部の部分の両側外面（図３では下面と上面）に設けられた突起軸で、ここではこの突起軸１８を基準にして、左側の指先形状の部位を突出外端部、一方、右側の切欠部分の部位を内端部とする。 FIG. 7A is a perspective view showing the outer surface (lower surface) 16 on one side of the first rattling prevention member 12a. FIG. 7B is a view from the arrow A (lower surface) side. FIG. 7C is an explanatory diagram viewed from the arrow B (inner end surface) side. Therefore, with reference to FIG. 7C, reference numeral 16 is a lower surface on one side, and reference numeral 17 is an upper surface on one side.
In FIG. 7, reference numeral 18 denotes a protrusion shaft provided on both outer surfaces (lower surface and upper surface in FIG. 3) of the half columnar central portion. Here, the left fingertip-shaped portion with reference to the protrusion shaft 18. Is the protruding outer end portion, and the right notch portion is the inner end portion.

図７の（ｃ）で示すように第１ガタツキ防止部材１２ａの内端部の一側下面１６と一側上面１７には、それぞれ切欠部が形成されている。しかして、一側下面１６の不番の切欠部分には、連続する複数個の被係合部分１９ａ、１９ｂが形成されている。一つの第１被係合部分１９ａは、図７の（ｃ）を基準にすると、内端部中央の仕切り壁２０と直交する奥側の水平状係合面（切欠凹所も含む）である。そして、もう一つの第２被係合部分１９ｂは奥側の水平状係合面１９ａから一側下面１６に至るまで下り坂状に形成された手前側の傾斜面である。図７の（ｂ）を基準にすると、手前側の傾斜面１９ｂは手前側から上り坂の傾斜状に見え、一方、被係合部分１９ｂに稜線ａを介して連続する水平状係合面１９ａは、やや右上がりの直線に見え、さらに、仕切り壁２０の垂直面２０ａが見える。 As shown in FIG. 7C, a notch portion is formed on the one side lower surface 16 and the one side upper surface 17 of the inner end portion of the first backlash preventing member 12a. Thus, a plurality of continuous engaged portions 19 a and 19 b are formed in the unnotched notched portion of the one side lower surface 16. One first engaged portion 19a is a horizontal engaging surface (including a notch recess) on the back side orthogonal to the partition wall 20 at the center of the inner end portion with reference to FIG. 7C. . The other second engaged portion 19b is a front inclined surface formed in a downward slope from the horizontal engaging surface 19a on the back side to the lower surface 16 on the one side. With reference to FIG. 7 (b), the inclined surface 19b on the near side looks like an upward slope from the near side, while the horizontal engaging surface 19a continues to the engaged portion 19b via the ridge line a. Can be seen as a straight line rising slightly to the right, and the vertical surface 20a of the partition wall 20 can be seen.

後述するストッパー４１Ａの係合部分４５は、第２施錠片１２のこれらの被係合部分１９ａ、１９ｂに対して、受け具８の中心線Ｏから錠箱１の中心線Ｏ１の位置ズレに対応して選択的に係脱する。ここでは、図３及び図４の係合状態を「施錠状態の１」の時とする。 An engaging portion 45 of the stopper 41A described later corresponds to a positional deviation of the center line O1 of the lock box 1 from the center line O of the receiving box 8 with respect to these engaged portions 19a and 19b of the second locking piece 12. And selectively disengage. Here, the engagement state of FIGS. 3 and 4 is assumed to be “1 in the locked state”.

すなわち、図３では、上下方向に交差状に並列する奥側の水平状係合面１９ａにストッパー４１Ａの係合部分４５が第１ガタツキ防止部材１２ａの奥側の第１被係合部分１９ａに係合している場合を示している。この施錠状態の１の時には、図４で示すように、上下のガタツキ防止片１２ｂ、１２ａの突出外端部の開き角度は「施錠状態の２」のときよりも大きい。 That is, in FIG. 3, the engagement portion 45 of the stopper 41 </ b> A is connected to the first engagement portion 19 a on the back side of the first rattling prevention member 12 a on the horizontal engagement surface 19 a on the back side that is arranged in parallel in the vertical direction. The case where it has engaged is shown. In the locked state 1, as shown in FIG. 4, the opening angle of the protruding outer end portions of the upper and lower rattle prevention pieces 12 b and 12 a is larger than that in the “locked state 2”.

付言すると、上下のガタツキ防止部材１２ｂ、１２ａは、その突出外端部が外に広がるようにその付勢手段１５のバネ力により外方向に付勢されている。一方、上下のストッパー４１、４１Ａは、仮想線で示すその付勢手段４８のバネ力により、係合部（ストッパー部）４５がガタツキ防止部材１２ｂ、１２ａの被係合部１９ａ、１９ｂに係合する方向にそれぞれ付勢されている。上下のストッパー４１、４１Ａの係合部（ストッパー部）４５がガタツキ防止部材１２ｂ、１２ａの被係合部１９ａ、１９ｂのいずれの位置に係合（施錠）するかは、受け具８の中心線Ｏと錠箱１の中心線Ｏ１の位置とが一致するか否かによる。 In other words, the upper and lower rattle prevention members 12b and 12a are urged outward by the spring force of the urging means 15 so that the protruding outer end portions spread outward. On the other hand, the upper and lower stoppers 41, 41A are engaged with the engaged portions 19a, 19b of the rattle prevention members 12b, 12a by the spring force of the urging means 48 indicated by phantom lines. Each direction is energized. Whether the engaging portion (stopper portion) 45 of the upper and lower stoppers 41, 41A is engaged (locked) to the engaged portion 19a, 19b of the rattle prevention member 12b, 12a is the center line of the support 8 It depends on whether O matches the position of the center line O1 of the lock box 1 or not.

ここで、「施錠状態の２」とは、図８及び図９の係合状態をいう。すなわち、施錠状態の２は、例えば室内外の温度差に起因する扉の一時的変形（反り）によって、錠箱１の中心線Ｏ１の位置が受け具８の中心線Ｏからズレた場合であり、図９では、例えば錠箱１の中心Ｏ１が受け具８の中心Ｏよりも室外ＯＵＴ側へズレた場合を示す。このような場合には、ストッパー４１Ａの係合部分の係合位置は、付勢手段１５のバネ力に抗して、第１被係合部分１９ａから第２被係合部分１９ｂへと移行（変位）する。この時、上下のストッパー４１、４１Ａは、それらの付勢手段４８のバネ力に抗して若干外拡変位する。 Here, “locked state 2” refers to the engaged state of FIGS. 8 and 9. That is, the locked state 2 is a case where the position of the center line O1 of the lock box 1 deviates from the center line O of the holder 8 due to, for example, temporary deformation (warping) of the door due to a temperature difference between the inside and outside of the room. FIG. 9 shows a case where, for example, the center O1 of the lock box 1 is shifted to the outdoor OUT side from the center O of the receptacle 8. In such a case, the engaging position of the engaging portion of the stopper 41A shifts from the first engaged portion 19a to the second engaged portion 19b against the spring force of the biasing means 15 ( Displacement). At this time, the upper and lower stoppers 41, 41 </ b> A are slightly expanded outwardly against the spring force of the urging means 48.

付言すると、図９で示すように錠箱１が室外（又は室内）へズレた時、受け具８の受止面８ａ（又８ｂ）で第１ガタツキ防止部材１２ａの突出外端部が押圧されかつ回転しようとするので、建具の反り具合に対応して、第１ガタツキ防止部材１２ａは付勢手段１５のバネ力に抗して垂直軸（突起軸）１８を支点に水平方向に回転し、ストッパー４１Ａの係合部分４５に対する第２施錠片１２の第１被係合部分１９ａの係合位置が第２被係合部分１９ｂへと自動的に位置変位する。その結果、図４と図９を対比すると明らかなように、上下のガタツキ防止部材の突出外端部の開き角度は「施錠状態の１」のときよりも小さくなる。 In addition, as shown in FIG. 9, when the lock box 1 is displaced outside (or indoor), the protruding outer end of the first rattle prevention member 12a is pressed by the receiving surface 8a (or 8b) of the receiving device 8. And since it tries to rotate, the first rattling prevention member 12a rotates in the horizontal direction with the vertical shaft (projection shaft) 18 as a fulcrum against the spring force of the urging means 15 in accordance with the warpage of the joinery. The engagement position of the first engaged portion 19a of the second locking piece 12 with respect to the engaging portion 45 of the stopper 41A is automatically displaced to the second engaged portion 19b. As a result, as is clear from a comparison between FIG. 4 and FIG. 9, the opening angle of the protruding outer end portions of the upper and lower rattling prevention members is smaller than that in the “locked state 1”.

それ故に、本発明では、シンプルな受け具８の使用が可能であり、しかも、受け具側でスライドボックスの位置調整をしなくても、戸枠側の受け具８に対する扉側の錠前Ｘに設けた側圧対策・ガタツキ対策用可動部材Ｙによって、受け具８の受止面（８ａ又は８ｂ）と第２施錠片１２の垂直係合面との間隙を自動的に解消することができる。 Therefore, in the present invention, the simple receiver 8 can be used, and the lock X on the door side with respect to the receiver 8 on the door frame side can be used without adjusting the position of the slide box on the receiver side. The provided movable member Y for countermeasure against side pressure / backlash can automatically eliminate the gap between the receiving surface (8a or 8b) of the receiver 8 and the vertical engagement surface of the second locking piece 12.

次に、図１６の（ａ）は、入力片１１に直接係合する第１のストッパー４１、図１６の（ｂ）は第１のストッパー４１を介して前記入力片１１に間接的に係合する第２のストッパー４１Ａを示す。 (8) Stopper 41, 41A
Next, (a) in FIG. 16 is a first stopper 41 that directly engages with the input piece 11, and (b) in FIG. 16 is indirectly engaged with the input piece 11 through the first stopper 41. A second stopper 41A is shown.

第１及び第２のストッパー４１、４１Ａは、前述した可動ベース板２１ａ（２１ｂ）に上下一対の横軸２８を介してそれぞれ軸支され、かつ、互いに同期して連動するように構成されている。 The first and second stoppers 41 and 41A are pivotally supported on the above-described movable base plate 21a (21b) via a pair of upper and lower horizontal shafts 28, and are configured to be synchronized with each other. .

図１６の（ａ）参照にして第１のストッパー４１を説明する。なお、第２のストッパー４１Ａは、第１のストッパー４１と同一或いは同様の構成であるから、便宜上同一の符号を付して重複する説明を省略する。 The first stopper 41 will be described with reference to FIG. Since the second stopper 41A has the same or similar configuration as the first stopper 41, the same reference numerals are used for convenience and redundant description is omitted.

符号４３は垂直部分で、この垂直部分４３の突起状上端部は、入力片１１の後入力部１４と係合する被係合部４４の機能を有する。 Reference numeral 43 denotes a vertical portion, and a protruding upper end portion of the vertical portion 43 has a function of an engaged portion 44 that engages with the rear input portion 14 of the input piece 11.

また、符号４５は垂直部分４３に不番の折り曲げ部分を介して前方側に延びる包丁形状の係合部分（ストッパー部）で、この係合部分４５はガタツキ防止部材ホルダー３１の長い切欠部３４に入り込み、前述したように中心線Ｏ、Ｏ１が一致するか否かによって、第２施錠片１２の被係合部分１９ａ、１９ｂと選択的に係脱する。 Reference numeral 45 denotes a knife-shaped engaging portion (stopper portion) extending forward through a vertical bent portion 43 through an unfolded bent portion. The engaging portion 45 is formed on the long notch portion 34 of the rattle prevention member holder 31. As described above, it is selectively engaged with or disengaged from the engaged portions 19a and 19b of the second locking piece 12 depending on whether or not the center lines O and O1 coincide with each other.

さらに、符号４６ａは前記ストッパー部４５の上辺（第２のストッパー４１Ａでは図面上下辺）に羽状に突出する突出部分４６の一部（例えば先端部）に形成された小突起状第２被係合部で、この第２被係合部４６ａは、閉扉時、錠箱１に直接又は間接的に設けた係止手段５１の係止端面５１ｂに係止され、一方、デッドボルトが完全に後退した時には、入力片１１を介して前記係止端面５１ｂから離れる（図１２参照）。 Further, reference numeral 46a denotes a small protrusion-like second engagement formed on a part (for example, a front end portion) of a protruding portion 46 protruding in a wing shape on the upper side of the stopper portion 45 (upper and lower sides in the second stopper 41A in the drawing). At the joint portion, the second engaged portion 46a is locked to the locking end surface 51b of the locking means 51 provided directly or indirectly on the lock box 1 when the door is closed, while the dead bolt is completely retracted. When it does, it leaves | separates from the said latching end surface 51b via the input piece 11 (refer FIG. 12).

なお、符号４８はストッパー４１，４１Ａ用の付勢手段で、これらのストッパー用付勢手段４８は、上下の横軸２８に中央部がそれぞれ巻装され、各ストッパー４１，４１Ａのストッパー部４５がそれぞれガタツキ防止部材に係合する方向へ付勢する。 Reference numeral 48 denotes urging means for the stoppers 41 and 41A. These urging means 48 for stoppers are wound around the upper and lower horizontal shafts 28 at their central portions, and the stopper portions 45 of the stoppers 41 and 41A are provided. Each is biased in a direction to engage with the anti-rattle member.

また、符号４９は可動部材戻し用の付勢手段であり、本実施例では、錠箱１の下端部に設けた固定軸５０に巻装され、一端部は錠箱１の内壁に圧接し、その他端部は、例えば可動ベース板２１のバネ端支持部２７に係合している。本実施例の可動部材戻し用の付勢手段４９は、錠箱１の係止端面５１ｂからストッパー４１、４１Ａの各第２被係合部４６ａが離れた瞬間、可動部材を引き戻す。その結果、可動部材に常に捕捉されている第２施錠片１２は、図１０で示すように錠箱１内に完全に入り込む。 Reference numeral 49 denotes a biasing means for returning the movable member. In this embodiment, the reference numeral 49 is wound around a fixed shaft 50 provided at the lower end portion of the lock box 1, and one end portion is pressed against the inner wall of the lock box 1. The other end portion is engaged with, for example, a spring end support portion 27 of the movable base plate 21. The urging means 49 for returning the movable member of this embodiment pulls back the movable member at the moment when the second engaged portions 46a of the stoppers 41 and 41A are separated from the locking end surface 51b of the lock box 1. As a result, the second locking piece 12 always captured by the movable member completely enters the lock box 1 as shown in FIG.

（９）係止手段の係止端面
図１２は錠箱１に直接形成した係止手段５１の一例を示す。係止手段５１は錠箱１の一側壁１ａと他側壁１ｂの内面にそれぞれ傾斜面と係止端面を有する山形状の突起片を固定することによっても達成することができるが、本実施例では、前記一側壁１ａと他側壁１ｂに直接形成している。 (9) Locking End Surface of Locking Means FIG. 12 shows an example of the locking means 51 formed directly on the lock box 1. The locking means 51 can also be achieved by fixing mountain-shaped projecting pieces each having an inclined surface and a locking end surface on the inner surface of one side wall 1a and the other side wall 1b of the lock box 1, but in this embodiment, The first side wall 1a and the second side wall 1b are directly formed.

すなわち、５２は上下一対の水平案内切欠部で、この水平案内切欠部５２の先端部側に傾斜面５１ａと、係止端面５１ｂを有する山形突起５１を設けている。本実施例では、可動式の第２施錠片１２を採用していることから、施錠時、第２施錠片１２が後退して受け金具８から外れないように係止手段５１の係止端面５１を介してストッパー４１，４１Ａの各第２被係合部４６ａを係止する。 That is, reference numeral 52 denotes a pair of upper and lower horizontal guide cutouts, and an angled surface 51a and a chevron projection 51 having a locking end face 51b are provided on the tip end side of the horizontal guide cutout 52. In the present embodiment, since the movable second locking piece 12 is employed, the locking end surface 51 of the locking means 51 is prevented so that the second locking piece 12 does not retract and come off the receiving metal fitting 8 during locking. The second engaged portions 46a of the stoppers 41, 41A are locked via the.

一方、解錠時に於いて、第１施錠片６が錠箱内へと後退動し始めた時（まだ第２施錠片１２が受け金具８に係合可能な時）、いわゆる「せっかちな人」が扉を開けようとすれば、図５で示すように、本実施例では第２施錠片１２の横幅が第１施錠片６のそれよりも大きく設定されているので、少なくとも第１施錠片６ではなく、第２施錠片１２の方にかかる。 On the other hand, at the time of unlocking, when the first locking piece 6 starts to move back into the lock box (when the second locking piece 12 can still be engaged with the receiving bracket 8), a so-called "impatient person" If the door is to be opened, as shown in FIG. 5, the width of the second locking piece 12 is set larger than that of the first locking piece 6 in this embodiment, so that at least the first locking piece 6 Instead, it takes the second locking piece 12.

そして、デッドボルト６が所定の後退条件を満たしたときには、換言すれば、図１１の（ａ）で示すように、デッドボルト６が錠箱１内に完全に後退した完全解錠位置であるときは、上下のストッパー４１，４１Ａは、デッドボルト６側の入力片１１の前入力部１３を介して所要量回転することから、各第２被係合部４６ａは各係止端面５１ｂから離れる。 When the dead bolt 6 satisfies the predetermined retraction condition, in other words, as shown in FIG. 11A, when the dead bolt 6 is in the completely unlocked position fully retracted into the lock box 1. Since the upper and lower stoppers 41 and 41A rotate by a required amount via the front input portion 13 of the input piece 11 on the dead bolt 6 side, each second engaged portion 46a is separated from each locking end surface 51b.

その結果、図１１の（ｂ）で示すように、第２施錠片１２は可動部材戻し用の付勢手段４９及び可動部材Ｙを介して錠箱１内に自動的に引っ込む。 As a result, as shown in FIG. 11B, the second locking piece 12 is automatically retracted into the lock box 1 via the urging means 49 for returning the movable member and the movable member Y.

まず、発明の実施の形態で示した実施例に於いて、第２施錠片をニ枚のガタツキ防止部材１２ａ、１２ｂで構成し、これらの突出外端部は鋏揺動自在に外拡変位ない内側変位するが、もちろん、これに限定するものではなく、発明の所期の目的を達成し得るのであれば、第２施錠片１２を一枚のガタツキ防止部材で構成しても良く、その形態はラッチ型である必要はない。したがって、第２施錠片１２の突出外端部に受け金具８の受止面８ａ、８ｂに当接する図示しないローラを軸支することもできる。 First, in the example shown in the embodiment of the invention, the second locking piece is constituted by two anti-rattle members 12a and 12b, and these projecting outer end portions are free to swing outward and displace. However, the present invention is not limited to this. Of course, the second locking piece 12 may be constituted by a single anti-rattle member as long as the intended purpose of the invention can be achieved. Need not be latched. Therefore, a roller (not shown) that contacts the receiving surfaces 8a and 8b of the receiving metal fitting 8 can be pivotally supported on the projecting outer end of the second locking piece 12.

また、ガタツキ防止部材１２ａ、１２ｂの内端部に形成した第２被係合部分１９ｂは傾斜状に形成されているが、ストッパーの係合部分（ストッパー部分）４５の方を傾斜状に形成しても良い。 Further, the second engaged portion 19b formed at the inner ends of the rattle prevention members 12a and 12b is formed in an inclined shape, but the engaging portion (stopper portion) 45 of the stopper is formed in an inclined shape. May be.

また、可動部材戻し用の付勢手段４９は、可動部材を構成する可動ベース板２１に設けたバネ端支持部２７を介して引き戻しているが、上下のストッパー４１，４１Ａの適宜箇所に係止させて戻すこともできる。 Further, the urging means 49 for returning the movable member is pulled back through the spring end support portion 27 provided on the movable base plate 21 constituting the movable member, but is latched at an appropriate position of the upper and lower stoppers 41 and 41A. It can also be returned.

さらに、上下のストッパー４１，４１Ａの連動構成に関しては、係合突片以外に、他の連係手段（垂直長孔、連結軸）を用いることもできる。なお、錠箱１の幅広の対向側壁１ａ、１ｂには、例えば図１０で示すように第２施錠片１２をスムースに案内するための短軸状のスペッサー軸２５が設けられている。 Furthermore, regarding the interlocking configuration of the upper and lower stoppers 41, 41A, other linking means (vertical long holes, connecting shafts) can be used in addition to the engaging protrusions. In addition, the wide opposing side walls 1a and 1b of the lock box 1 are provided with a short shaft-like spacer shaft 25 for smoothly guiding the second locking piece 12 as shown in FIG.

次に、発明の実施の形態で示した一実施例（第１実施例）は、本発明の所期の目的のみならず、全ての目的を充足させるためにやや複雑化しているが、図１７及び図１８で示すように、基本的な構成部材の組み合わせによっても達成することができる。 Next, although one example (first example) shown in the embodiment of the invention is slightly complicated to satisfy all purposes, not only the intended purpose of the present invention, FIG. And as shown in FIG. 18, it can also be achieved by a combination of basic components.

ここでは、図１７及び図１８に示した発明を第２実施例とし、第１実施例と同一の符号を用いて簡単に説明する。この第２実施例も、第１実施例と同様、錠箱１にデッドボルト６Ａの内端部に突出入力片１１Ａが固定的に設けられている。そして、突出入力片１１Ａの突出端部１１ｃの後端部に押し出し用第１係合部１４Ａが設けられ、一方、突出端部１１ｃの先端部に引き戻し用第２係合部１３Ａが設けられている。 Here, the invention shown in FIG. 17 and FIG. 18 will be described as a second embodiment, and will be briefly described using the same reference numerals as those in the first embodiment. In the second embodiment, similarly to the first embodiment, a protruding input piece 11A is fixedly provided on the inner end portion of the dead bolt 6A in the lock box 1. Then, the first engaging portion 14A for extrusion is provided at the rear end portion of the protruding end portion 11c of the protruding input piece 11A, while the second engaging portion 13A for pulling back is provided at the distal end portion of the protruding end portion 11c. Yes.

また、第１実施例と同様、錠箱１には、第１施錠片６Ａ用の側圧対策・扉のガタツキ対策用の可動部材Ｙが設けられている。可動部材Ｙに保持された第２施錠片１２Ａは、第１実施例と同様、錠箱１の上下方向に配設されている。また、第２施錠片１２Ａはデッドボルト６Ａと同様に進退動自在に設けられている。 Similarly to the first embodiment, the lock box 1 is provided with a movable member Y for the side pressure countermeasure and the door rattling countermeasure for the first locking piece 6A. The second locking piece 12A held by the movable member Y is arranged in the vertical direction of the lock box 1 as in the first embodiment. Further, the second locking piece 12A is provided so as to be movable forward and backward similarly to the dead bolt 6A.

そして、第２施錠片１２Ａは、その一側壁（例えば上壁）から突出して突出入力片１１Ａの第１係合部１４Ａと第２係合部１３Ａに選択的に係合する係合腕４４Ａを有している。であるから、第２実施例では可動部材戻し用の付勢部材を有していない。 The second locking piece 12A has an engaging arm 44A that protrudes from one side wall (for example, the upper wall) and selectively engages with the first engaging portion 14A and the second engaging portion 13A of the protruding input piece 11A. Have. Therefore, the second embodiment does not have an urging member for returning the movable member.

しかして、第２施錠片１２Ａは、施錠時、デッドボルト６Ａがフロント７から突出すると、突出入力片１１Ａの押し出し用第１係合部１４Ａに押し出されて受け金具８に係合するように突出する反面、解錠時、デッドボルト６Ａが錠箱１内に後退すると、前記突出入力片１１Ａの引き戻し用第２係合部１３Ａに引き戻されて錠箱１内に引っ込む。したがって、第２実施例では、側圧受け片１２Ａを錠箱１内に引き戻すための付勢手段４９は発明の積極的な特定（限定）要件ではない。 Thus, when the dead bolt 6A protrudes from the front 7 at the time of locking, the second locking piece 12A is pushed out by the pushing first engaging portion 14A of the protruding input piece 11A so as to be engaged with the receiving metal fitting 8. On the other hand, at the time of unlocking, when the dead bolt 6A is retracted into the lock box 1, it is pulled back into the lock box 1 by being pulled back to the second engaging portion 13A for pulling back of the protruding input piece 11A. Therefore, in the second embodiment, the urging means 49 for pulling back the side pressure receiving piece 12A into the lock box 1 is not a positive specification (limitation) requirement of the invention.

次に、図１９に第２施錠片１２Ａの第３実施例を示す。説明の便宜上第1実施例と同一の符号を用いる。重複する説明は割愛する。 Next, FIG. 19 shows a third embodiment of the second locking piece 12A. For convenience of explanation, the same reference numerals as those in the first embodiment are used. Duplicate explanations are omitted.

図１９の（ａ）、（ｂ）及び（ｃ）は、図７の（ａ）、（ｂ）及び（ｃ）に相当する。特に図１９の（ｃ）と図７のそれとを比較すると明らかなように、第２実施例の第２施錠片１２Ａを構成するガタツキ防止部材１２ａ（ガタツキ防止部材１２ｂも同じ）の被係合部１９ａ、１９ｂの連続関係は、傾斜状ではなく、段差或いは階段状に形成されている。 (A), (b), and (c) in FIG. 19 correspond to (a), (b), and (c) in FIG. In particular, as can be seen by comparing FIG. 19C with that of FIG. 7, the engaged portion of the rattle prevention member 12a (the same applies to the rattle prevention member 12b) constituting the second locking piece 12A of the second embodiment. The continuous relationship between 19a and 19b is not a slope but a step or a staircase.

この第２実施例では、特に、建具施工時の取付け位置の誤差に起因して、例えば図９で示すように錠箱１が室外ＯＵＴへずれ、その結果、受け具８の受止面８ａ、８ｂで第１ガタツキ防止部材１２ａの突出外端部が押圧され得る状態になった場合に於いて、第１ガタツキ防止部材１２ａが垂直軸１８を支点にして、かつ、その付勢手段１５のバネ力に抗して角度を狭める方向（図９では矢印方向）へ若干回転した場合に、第１ガタツキ防止部材１２ａに対するストッパー４１Ａ（ストッパー４１の場合も同様）の係合位置が、第1被係合部１９ａではなく、第1被係合部１９ｂの方に変わる。 In this second embodiment, in particular, due to an error in the mounting position during the construction of the joinery, for example, as shown in FIG. 9, the lock box 1 is shifted to the outdoor OUT, and as a result, the receiving surface 8 a of the receiving tool 8, When the projecting outer end portion of the first rattle prevention member 12a can be pressed at 8b, the first rattle prevention member 12a uses the vertical shaft 18 as a fulcrum and the spring of the biasing means 15 In the case of slight rotation in the direction of narrowing the angle against the force (in the direction of the arrow in FIG. 9), the engagement position of the stopper 41A (also in the case of the stopper 41) with respect to the first rattle prevention member 12a is Instead of the joint portion 19a, the first engaged portion 19b is changed.

付言すると、第２実施例では、建具施工時の当初から図９で示すように左右の中心線ＯとＯ１が不一致であることから、まず、扉の閉戸時、受け具８の受止面８ａに対するガタツキ防止部材１２ａ（ガタツキ防止部材１２ｂも同じ）の当り具合によって、第１・第２ガタツキ防止部材１２ａ、１２ｂ同士の角度を自動的に決め（受け具側の間隙を調整しなくても）、次に、角度が設定されている第１・第２ガタツキ防止部材１２ａ、１２ｂの複数個の被係合部１９ａ、１９ｂのいずれかにストッパーの係合部分（ストッパー部）４５を係合させることにしている。 In addition, in the second embodiment, since the left and right center lines O and O1 do not coincide as shown in FIG. 9 from the beginning when the fitting is performed, first, when the door is closed, the receiving surface of the receiving member 8 is closed. The angle between the first and second anti-rattle members 12a, 12b is automatically determined according to the degree of contact of the anti-rattle member 12a with respect to 8a (the same applies to the anti-rattle member 12b) (without adjusting the gap on the receiving side). Next, the engaging portion (stopper portion) 45 of the stopper is engaged with any one of the plurality of engaged portions 19a and 19b of the first and second anti-rattle members 12a and 12b whose angles are set. I will let you.

そのために、扉の閉戸時に可動部材２１，３１，３５を介してフロント７から突出したガタツキ防止部材１２ａ、１２ｂのいずれかが、受け具８の受止面８ａ、８ｂのいずれかに押圧されて水平方向に回転した後に、ガタツキ防止部材の被係合部分１９ａ、１９ｂに対するストッパーの係合部分４５の位置が自動的に変わる。 Therefore, any of the anti-rattle members 12a and 12b protruding from the front 7 via the movable members 21, 31, and 35 when the door is closed is pressed against either of the receiving surfaces 8a and 8b of the receiving device 8. The position of the engaging portion 45 of the stopper with respect to the engaged portions 19a and 19b of the anti-rattle member automatically changes after rotating in the horizontal direction.

なお、図１２で示すように錠箱１には山形状の係止手段５１が設けられていることから、上下のストッパー４１，４１Ａは、施錠時、前記係止手段５１の先端部側に傾斜面５１ａを乗り越えする際に各付勢手段４８のバネ力に抗して互いに外方向へ開き、完全施錠位置にて（係止手段５１を乗り越えた後に）、自動的に位置決めされているガタツキ防止部材１２ａ、１２ｂの被係合部１９ａ、１９ｂのいずれかに係合する。 As shown in FIG. 12, since the lock box 1 is provided with a mountain-shaped locking means 51, the upper and lower stoppers 41 and 41A are inclined toward the distal end side of the locking means 51 during locking. When moving over the surface 51a, the springs of the urging means 48 open against each other against the spring force and are automatically positioned at the fully locked position (after over the locking means 51) to prevent rattling. Engage with any one of the engaged portions 19a and 19b of the members 12a and 12b.

したがって、前記被係合部１９ａ、１９ｂの連続関係は、１段式、２段式、３段式という具合に多段式に形成することもできる。或いはストパー４１，４１Ａの係合部分４５の方を段差或いは階段式に形成することも可能である。 Accordingly, the continuous relationship of the engaged portions 19a and 19b can be formed in a multistage manner such as a one-stage type, a two-stage type, and a three-stage type. Alternatively, the engaging portion 45 of the stoppers 41 and 41A can be formed in a stepped or stepped manner.

本発明は、主に錠前や建具の業界で利用される。 The present invention is mainly used in the locksmith and joinery industries.
