Description

本発明は建具用錠前に関し、特に、施錠状態、解錠状態、連続解錠状態等の状態信号を検出する検出装置を備えた建具用錠前に関する。 The present invention relates to a lock for joinery, and more particularly to a lock for joinery including a detection device that detects a state signal such as a locked state, an unlocked state, and a continuous unlocked state.

特許文献１の図８には、「電気錠の駆動箱に回動可能に支承された駆動軸に、センサー用識別部を有する回転板を一体的に設け、一方、前記回転体の外面に対して配設され、かつ前記センサー用識別部の位置状態を検出するフォトセンサーを備えているセンサー支持体を駆動箱内に固定し、前記駆動箱内或いは駆動箱外の箇所に前記フォトセンサーから出力された検知信号を取得して前記駆動モータを駆動制御する制御部を設けた電気錠の駆動軸駆動機構の制御装置」が記載されている。 FIG. 8 of Patent Document 1 shows that “a rotary plate having a sensor identification portion is integrally provided on a drive shaft that is rotatably supported by a drive box of an electric lock. And a sensor support provided with a photosensor for detecting the position state of the sensor identification unit is fixed in the drive box, and output from the photosensor to a location inside the drive box or outside the drive box. The control device for the drive shaft drive mechanism of the electric lock provided with a control unit for acquiring the detected signal and controlling the drive motor is described.

この特許文献１は、出願人が次の理由から貴庁に提案したものである。すなわち、電気錠の施・解錠状態（具体的には、デッドボルトの位置、サムターン摘みのポジション位置等）を検知する場合に於いて、接触型スイッチの可動接片を用いる方式は、安定した位置検出及び駆動箱内の省スペース化を両立するという発明の課題を十分に達成することができないことから、駆動モータ用の駆動停止信号を安定的に取得する、駆動箱内の省スペースを有効的に活用する、駆動箱内へセンサーを容易に組込みこむことができる等の諸問題を十分に解決することである。 This patent document 1 was proposed to your office by the applicant for the following reasons. In other words, the method using the movable contact piece of the contact type switch is stable when detecting whether the electric lock is applied or unlocked (specifically, the position of the dead bolt, the position of the thumb turn knob, etc.). Since the problem of the invention of achieving both position detection and space saving in the drive box cannot be sufficiently achieved, space saving in the drive box that stably acquires the drive stop signal for the drive motor is effective. It is to solve various problems such as efficient use and easy incorporation of the sensor into the drive box.

ところで、建具用錠前の錠箱は、例えば扉の自由端部に取り付けられるので、普通一般に上下方向に長く、扉の前後方向の幅は非常に狭い。そして、この長尺状錠箱の内部空間には、例えば電気錠であれば、駆動源としての駆動モータ、電気錠用プリント基板、動力伝達手段、クラッチ機構、錠前の施・解錠に関する状態信号検出装置、ダルマ、デッドボルト等の施・解錠機構を構成する各部材や部品を組み込むので、内部空間を有効的に活用することが求められる。そこで、現在、この種の錠箱が、普通一般に前後方向の幅が狭く、内部空間に余裕がないことを前提として、前記状態信号検出装置の工夫が要望されている。 By the way, since the lock box before the lock for joinery is attached to, for example, the free end of the door, it is generally long in the vertical direction and the width in the front-rear direction of the door is very narrow. And in the internal space of this long lock box, if it is an electric lock, for example, a drive motor as a drive source, a printed circuit board for electric lock, a power transmission means, a clutch mechanism, a status signal relating to locking / unlocking of the lock Since each member or part constituting the application / unlocking mechanism such as a detection device, dharma, or deadbolt is incorporated, it is required to make effective use of the internal space. Therefore, at present, there is a demand for a device for the state signal detection device on the premise that this type of lock box is generally narrow in the front-rear direction and has no room in the internal space.

（１）環境部材
図１は本発明の主要部を適用した電気錠の概略説明図（概念図）である。図２は図１に示した電気錠の一例を示す概略説明図である（なお、図２、図３等は本発明の主要部のみを示し、クラッチ機構等は省略している）。 (1) Environmental Member FIG. 1 is a schematic explanatory diagram (conceptual diagram) of an electric lock to which the main part of the present invention is applied. FIG. 2 is a schematic explanatory view showing an example of the electric lock shown in FIG. 1 (note that FIG. 2, FIG. 3 and the like show only the main part of the present invention, and the clutch mechanism and the like are omitted).

まず、これらの図に於いて、Ｘは電気的にも機械的にもデッドボルト（以下、「デッド」ともいう。）が出没可能な電気錠、１は戸枠、２は受け具、３は開閉体としての扉、４は長尺状の錠箱、６は制御部、７はコネクタを含む配線手段、８は電気錠制御用プリント基板、９はフロント板４ａに形成した開口、１０は電気的駆動源（例えば駆動モータ）、１１は動力伝達手段、１２は動力伝達手段側からの動力を伝達又は後述するダルマ側からの動力を切断するクラッチ機構、そして、Ｙは電気錠Ｘの施・解錠状態に関する状態信号を検出する検出装置、１３はダルマ、１４はダルマの回動に基づいて前記錠箱４の開口９から進退動するデッドである。 First, in these drawings, X is an electric lock in which a dead bolt (hereinafter also referred to as “dead”) can be moved both electrically and mechanically, 1 is a door frame, 2 is a support, 3 is Door as an opening / closing body, 4 is a long lock box, 6 is a control unit, 7 is a wiring means including a connector, 8 is an electric lock control printed circuit board, 9 is an opening formed in the front plate 4a, 10 is an electric 11 is a power transmission means, 11 is a power transmission means, 12 is a clutch mechanism that transmits power from the power transmission means side or cuts power from a dharma side, which will be described later, and Y is an application / control of the electric lock X. A detection device for detecting a status signal relating to the unlocked state, 13 is a dharma, and 14 is a dead that moves forward and backward from the opening 9 of the lock box 4 based on the rotation of the dharma.

次に、図１に於いて、制御部６は出力部１５を有し、該出力部１５には表示部１６が電気的に接続している。また、制御部６には解錠信号発生手段１７や図示しないモード切換手段等も電気的に接続している。制御部６は、例えば室内の適宜箇所に配設された住宅用電気錠操作盤の操作パネルに設けられ、該操作パネルは図示しない連続解錠用ボタン、自動施錠用ボタン、一回解錠用ボタン等の複数固の操作ボタンを有している。これらの信号処理の関しては本発明の特定要件ではないので、詳細な説明は割愛する。 Next, in FIG. 1, the control unit 6 has an output unit 15, and a display unit 16 is electrically connected to the output unit 15.

And the lock X for joinery of this invention is applied to the electric lock with which many members and components are integrated in the internal space of the elongate lock box 4 desirably.

（３）本発明の特徴事項
本発明の特徴事項は、扉の前後方向の幅が非常に狭く、内部空間に余裕がない長尺状の錠箱４に組み込まれた検出装置Ｙで、該検出装置Ｙは、フォトセンサー２１と、テコ式スイッチ片２３と、該テコ式スイッチ片用の復帰バネ２４とをそれぞれ備えている。 (3) Features of the present invention The features of the present invention are the detection device Y incorporated in the long lock box 4 having a very narrow door width in the front-rear direction and no internal space. The device Y includes a photo sensor 21, a lever switch piece 23, and a return spring 24 for the lever switch piece.

前記検出装置Ｙは、施錠状態の図２、解錠状態の図３等で示すように、デッドボルト１４の付近に支軸３６を介して回転自在に配設されたテコ式スイッチ片２３と、このテコ式スイッチ片の回転態様により、錠前の施・解錠状態を検出するフォトセンサー２１と、前記テコ式スイッチ片を初期位置へと戻すための復帰バネ２４とから成り、前記テコ式スイッチ片２３は、その長片部分２３ａの先端部が遮蔽状態に接近乃至離れて該遮蔽状態を解消するように、一方、その短片部分２３ｂの端部が前記デッドボルト１４の当り部３２と押圧状態で係脱するように中間部寄りの部位２３ｃが軸支されている。そして、この第１実施形態の前記支軸３６は、例えば図２で示すように、デッドボルト１４の当り部３２の若干上方で、かつ錠箱４のフロント板４ａの内面近傍に横設軸架され、しかも、テコ式スイッチ片２３の長片部分２３ａの先端部がフォトセンサー２１の上位に位置付けられているので、望ましくは、該スイッチ片の前記長片部分の先端部が前記フォトセンサーから離れる方向へ付勢する復帰バネ２４を含む（図３参照）。 As shown in FIG. 2 in the locked state, FIG. 3 in the unlocked state, etc., the detection device Y includes a lever-type switch piece 23 that is rotatably disposed around the dead bolt 14 via a support shaft 36; The lever-type switch piece comprises a photosensor 21 for detecting the locked / unlocked state of the lock, and a return spring 24 for returning the lever-type switch piece to the initial position. 23, so that the tip of the long piece portion 23a approaches or separates from the shielded state to cancel the shielded state, while the end of the short piece portion 23b is in a pressed state with the contact portion 32 of the dead bolt 14 A portion 23c near the intermediate portion is pivotally supported so as to be engaged and disengaged. The support shaft 36 of the first embodiment is a horizontal shaft slightly above the contact portion 32 of the dead bolt 14 and in the vicinity of the inner surface of the front plate 4a of the lock box 4 as shown in FIG. In addition, since the distal end portion of the long piece portion 23a of the lever-type switch piece 23 is positioned above the photosensor 21, desirably, the distal end portion of the long piece portion of the switch piece is separated from the photosensor. It includes a return spring 24 that biases in the direction (see FIG. 3).

（４）検出装置Ｙの具体的構成
図４は検出装置Ｙの主要部を分解的に示した概略説明図、図５は解錠状態から施錠状態になった場合の概略説明図である。これらの図を参照にして検出装置Ｙの具体的構成を説明する。 (4) Specific Configuration of Detection Device Y FIG. 4 is a schematic explanatory view showing the main part of the detection device Y in an exploded manner, and FIG. 5 is a schematic explanatory view when the unlocked state is changed to the locked state. A specific configuration of the detection device Y will be described with reference to these drawings.

まず、状態信号検出手段としてのフォトセンサー２１は、前述したようにデッドボルト１４の上辺に突設した当り部３２の先端面と押圧状態で係脱するように該デッドボルト１４の上辺付近に配設されている。本実施形態では、図２及び図３で示すように、センサー基板３５を介して錠箱４の一側内壁面に固定されている。 First, the photosensor 21 as the state signal detecting means is arranged in the vicinity of the upper side of the dead bolt 14 so as to be engaged with and disengaged from the front end surface of the contact portion 32 protruding from the upper side of the dead bolt 14 as described above. It is installed. In this embodiment, as shown in FIGS. 2 and 3, it is fixed to one inner wall surface of the lock box 4 through the sensor substrate 35.

フォトセンサー２１は、周知のように、発光側（ＬＥＤ）の側壁部２１ａと、該発光側の側壁部に所定間隙ａを有して対向する受光側（フォトトランジスタ）の側壁部２１ｂとを有している。ここで「状態信号」とは、解錠状態、施錠状態、連続解錠状態等をいう。具体的には、例えばデッド１４が錠箱４の開口９から完全に突出した状態（その状態を「原点位置」とする。）、デッド１４が錠箱４内に完全に後退した状態である。したがって、本実施形態のフォトセンサー２１は、錠前の状態信号を検出するものである。 As is well known, the photosensor 21 has a light emitting side (LED) side wall portion 21a and a light receiving side (phototransistor) side wall portion 21b opposed to the light emitting side wall portion with a predetermined gap a. doing. Here, the “status signal” means an unlocked state, a locked state, a continuous unlocked state, or the like. Specifically, for example, the dead 14 completely protrudes from the opening 9 of the lock box 4 (this state is referred to as “origin position”), and the dead 14 is completely retracted into the lock box 4. Therefore, the photo sensor 21 of the present embodiment detects a lock state signal.

次に、スイッチ片２３は、その中間部寄りの部位が支軸３６を介して揺動自在に軸支されている。本実施形態の支軸３６は、前述したように、デッドボルト１４の上辺かつフロント板４ａの内面近傍に位置している。 Next, the switch piece 23 is pivotally supported via a support shaft 36 at a portion near the intermediate portion thereof. As described above, the support shaft 36 of this embodiment is located near the upper side of the dead bolt 14 and the inner surface of the front plate 4a.

このスイッチ片２３は、「テコの原理」を応用したものであり、例えば図５の支軸３６を基準にすると、図面上右側の人差し指状に延びた長片部分２３ａの先端部は、フォトセンサー２１の発光側（ＬＥＤ）と受光側（フォトトランジスタ）に対して、互いを遮蔽するように接近乃至遮蔽状態を解消するように離れることが可能であり、一方、図面上左側の親指状の短片部分２３ｂの端部は、デッドボルト１４の上辺の段差状当り部３２と係脱することが可能である。 The switch piece 23 is obtained by applying the "principle of leverage", for example, referred to the support shaft 36 in FIG. 5, the tip of the long piece portion 23a extending in the drawing on the right side of the index finger shaped, photo emission side of the sensor 21 (LED) and a light receiving side with respect to (a phototransistor), it is possible to leave to eliminate the approaching to the closing state to shield one another, whereas, on the drawing left side of the thumb-like The end portion of the short piece portion 23 b can be engaged with and disengaged from the stepped contact portion 32 on the upper side of the dead bolt 14.

ところで、本実施形態では、テコ式スイッチ片２３の中間部寄りの部位２３ｃには軸孔３７が形成されている。また、長片部分２３ａの先端部には、そのややは幅広の下端部がフォトセンサー２１の所定間隙ａに入り込み乃至出たりすることができる細長状の遮蔽突片３８が一体的に設けられている。そして、該細長状の遮蔽突片３８の上端部には、長片部分２３ａに直交して水平方向に延在する棒状のバネ端支持部３９が形成されている。したがって、本実施例のテコ式スイッチ片２３は、支軸３６を基準にすると、遮蔽突片３８等を有する長片部分２３ａの方が短片部分２３ｂよりも重い。 By the way, in this embodiment, the shaft hole 37 is formed in the site | part 23c near the intermediate part of the lever-type switch piece 23. FIG. In addition, an elongated shielding protrusion 38 is integrally provided at the distal end of the long piece portion 23a so that the slightly wide lower end thereof can enter or exit the predetermined gap a of the photosensor 21. Yes. A rod-like spring end support portion 39 extending in the horizontal direction perpendicular to the long piece portion 23a is formed at the upper end of the elongated shielding protrusion 38. Therefore, in the lever type switch piece 23 of the present embodiment, the long piece portion 23a having the shielding projection piece 38 and the like is heavier than the short piece portion 23b when the support shaft 36 is used as a reference.

最後に、テコ式スイッチ片２３を所定方向へ付勢する復帰バネ２４は、その中央部分２４ａがフォトセンサー２１の上方に位置する固定支軸４１に巻装され、一端部２４ｂは錠箱内の支持ピン４２に支持され、他端部２４ｃは前述の棒状バネ端支持部３９に圧接している。付言すると、本実施形態では、復帰バネ２４は、テコ式スイッチ片２３の長片部分の先端部の遮蔽突片３８がフォトセンサー２１から離れる方向へと付勢している。 Finally, the return spring 24 for urging the lever-type switch piece 23 in a predetermined direction is wound around a fixed support shaft 41 whose central portion 24a is located above the photosensor 21, and one end 24b is provided in the lock box. Supported by the support pin 42, the other end 24c is in pressure contact with the above-described rod-shaped spring end support 39. In other words, in the present embodiment, the return spring 24 biases the shielding protrusion 38 at the tip of the long piece of the lever-type switch piece 23 in a direction away from the photosensor 21.

（５）作用
ここで図２及び図３を参照にすると、第１実施形態では、検出装置Ｙを電気錠Ｘに適用しているので、駆動源としての駆動モータ１０が起動すると、動力伝達機構１１を構成する歯車体２０が矢印で示す方向へそれぞれ回転することにより、ダルマ１３が矢印で示す反時計方向又は時計方向へと回転し、デッドボルト１４が進出又は後退する。その時、デッドボルト１４の当り部３２がテコ式スイッチ片２３の短片部分２３ｂの端部に接離する結果、フォトセンサー２１が「ＯＮ」、「ＯＦＦ」の状態信号を検知することができる。 (5) Operation Here, referring to FIG. 2 and FIG. 3, in the first embodiment, since the detection device Y is applied to the electric lock X, when the drive motor 10 as a drive source is activated, a power transmission mechanism When the gear body 20 constituting 11 rotates in the direction indicated by the arrow, the dharma 13 rotates counterclockwise or clockwise indicated by the arrow, and the dead bolt 14 advances or retracts. At that time, as a result of the contact portion 32 of the dead bolt 14 coming into contact with and separating from the end portion of the short piece portion 23b of the lever type switch piece 23, the photosensor 21 can detect the “ON” and “OFF” state signals.

すなわち、図２は施錠状態の概略説明図であるが、このように解錠状態から施錠状態になった場合を図５で示す。解錠状態（図３を参照）では、当り部３２はテコ式スイッチ片２３の短片部分２３ｂの端部から離れるので、テコ式スイッチ片２３は復帰バネ２４のバネ力により、フォトセンサー２１の所定間隙ａから離れる。 That is, FIG. 2 is a schematic explanatory view of the locked state, and FIG. 5 shows the case where the unlocked state is changed to the locked state. In the unlocked state (see FIG. 3), the contact portion 32 is separated from the end of the short piece portion 23 b of the lever-type switch piece 23, so that the lever-type switch piece 23 is predetermined by the spring force of the return spring 24. Leave the gap a.

次に図１０は、図９の第５実施形態と同様に機械式錠前Ｘ１（これに電気錠の構成部材を加味することも可能）に検出装置Ｙ４を適用した第６実施形態であり、図２と同様に施錠状態の説明図。この第６実施形態が第１実施形態と主に異なる点は、（ａ）当り部３２Ｃを有する部材が、デッドではなく、水平方向或いは斜め方向に案内部材５１を介してスライドする摺動部材、例えば単数又は複数のラック板５２である点、（ｂ）摺動部材５２はダルマ１３からの動力を受ける動力伝達機構１１Ａを構成する歯車体２０の噛合する点、（ｃ）検出装置Ｙ４はプリント基板８とラック板５２の間に配設されている点である。 Next, FIG. 10 is a sixth embodiment in which the detection device Y4 is applied to the mechanical lock X1 (which can be added with the components of an electric lock) as in the fifth embodiment of FIG. The explanatory drawing of a locked state similarly to 2. FIG. This sixth embodiment is mainly different from the first embodiment in that (a) the member having the contact portion 32C is not dead, but slides through the guide member 51 in the horizontal direction or oblique direction, For example, one or more rack plates 52, (b) the sliding member 52 meshes with the gear body 20 constituting the power transmission mechanism 11A that receives power from the dharma 13, and (c) the detection device Y4 is a print. The point is that it is disposed between the substrate 8 and the rack plate 52.

最後に図１１乃至図１７は、デッドボルト１４を施錠方向へ突出させる動力源として「駆動バネ７０」を用いた錠前Ｘ２に検出装置Ｙ１を適用した第７実施形態である。この第７実施形態の錠前の基本的構成は、本出願人が先願として貴庁に提出済みである（例えば特願２００９−２９２７５４）。 Finally, FIGS. 11 to 17 show a seventh embodiment in which the detection device Y1 is applied to a lock X2 that uses a “drive spring 70” as a power source that causes the dead bolt 14 to protrude in the locking direction. The basic configuration of the lock of the seventh embodiment has already been submitted to your office by the applicant as a prior application (for example, Japanese Patent Application No. 2009-292754).

この錠前Ｘ２は、錠箱４内に、デッドボルト１４の没入状態を保持する摺動部材６１及び該摺動部材用ストッパレバー６２を含むロック機構６０と、該ロック機構にロックされるダルマ１３Ａと、前記錠箱側に一端部が取付けられ、一方、他端部がダルマ側に取付けられた動力源としての付勢手段７０とを組込み、前記デッドボルトが錠箱内に没入している解錠時（図１１、図１２）、前記ダルマ１３Ａが、図示しない操作部材の操作力により施錠方向へ回転し始めた初期動作時に、該ダルマ１３Ａと共働する前記摺動部材６１のラック板６１ａの位置変位を介して前記ロック機構６０を構成するストッパレバー６２によるロック状態が解かれると、以後、前記ダルマ１３Ａは、前記付勢手段７０の付勢力により自動的に施錠方向へと回動する。 The lock X2 includes a lock mechanism 60 including a sliding member 61 and a stopper lever 62 for the sliding member for holding the dead bolt 14 in the locked state in the lock box 4, and a dharma 13A locked to the locking mechanism. An unlocking device in which one end portion is attached to the lock box side and an urging means 70 as a power source having the other end portion attached to the dharma side is incorporated, and the dead bolt is immersed in the lock box. During the initial operation when the dharma 13A starts to rotate in the locking direction by the operating force of the operating member (not shown), the rack plate 61a of the sliding member 61 that cooperates with the dharma 13A When the locked state by the stopper lever 62 constituting the lock mechanism 60 is released through the position displacement, the dharma 13A is automatically rotated in the locking direction by the urging force of the urging means 70 thereafter. .

そして、前記摺動部材６１は、少なくともダルマ１３Ａと噛合するラック板６１ａと、このラック板と互いに共働するように係合するスライダ板６１ｂとから成り、ダルマの初期動作時、前記ラック板６１ａが前記スライダ板６１ｂによも先行移動して前記ストッパレバー６２によるロック状態が解かれる。 The sliding member 61 includes at least a rack plate 61a that meshes with the dharma 13A and a slider plate 61b that engages with the rack plate so as to cooperate with each other. However, the slider plate 61b also moves in advance to unlock the stopper lever 62.

また、前記ダルマ１３Ａは、半径外方向に延伸する係合アーム１３ａを有し、前述した摺動部材６１が解錠位置から施錠位置まで移動する際、前記係合アーム１３ａの先端部でもって摺動部材の受け部分を追随的に後押する。 Further, the dharma 13A has an engagement arm 13a extending in a radially outward direction. When the sliding member 61 moves from the unlocking position to the locking position, the dharma 13A slides at the distal end of the engagement arm 13a. The receiving part of the moving member is boosted in a follow-up manner.

また、図１６及び図１７で示すように、駆動源としての付勢手段７０は、捩じりコイルバネ７１と、該捩じりコイルバネの螺旋状中央部７１ｂを横柱で支持する可動のバネガイド７２とから成る。さらに、前記摺動部材６１は、図１４で示すように、ストッパレバー６２の先端部がスライダ板６１ａの受け係合部６１ｃから離れると、錠箱４の前壁の内面と錠箱の後壁の内面の間を、図示しない傾斜案内部を介して傾方向に移動することができる。 Further, as shown in FIGS. 16 and 17, the urging means 70 as a drive source includes a torsion coil spring 71 and a movable spring guide 72 that supports the spiral central portion 71b of the torsion coil spring with a horizontal column. It consists of. Further, as shown in FIG. 14, the sliding member 61 has an inner surface of the front wall of the lock box 4 and a rear wall of the lock box when the tip of the stopper lever 62 is separated from the receiving engagement part 61c of the slider plate 61a. It is possible to move between the inner surfaces of the first and second inner surfaces in an inclination direction via an inclination guide portion (not shown).

さらに、ダルマ１３Ａには作動アーム６４の上端部が枢支され、一方、該作動アーム６４の下端部には、錠箱側に設けられた案内切欠部６５に直接又は間接的な案内される横杆状のデッド用ストッパ６６を取付け、該デッド用ストッパ６６は、前記デッドボルト１４が付勢手段７０の付勢力によって完全に突出した施錠時には、前記案内切欠部６５に案内されてデッドボルト１４の後端面をロックする。なお、この錠前Ｘ２の具体的構成は、発明の特定要件ではないので、細部的事項の説明は割愛する。 Further, the upper end of the operating arm 64 is pivotally supported by the dharma 13A, while the lower end of the operating arm 64 is laterally guided directly or indirectly by a guide notch 65 provided on the lock box side. A hook-like dead stopper 66 is attached, and the dead stopper 66 is guided by the guide notch portion 65 when the dead bolt 14 is completely protruded by the urging force of the urging means 70 and the dead bolt 14 is Lock the rear end face. In addition, since the specific structure of this lock X2 is not the specific requirement of invention, description of a detailed matter is omitted.

上記構成に於いて、この錠前Ｘ２の摺動部材６１は、少なくともダルマ１３Ａと噛合するラック板６１ａと、このラック板と互いに共働するように接合状態で係合するスライダ板６１ｂとから成るが、ダルマ１３Ａが回転し始める初期の動作時、前記ラック板６１ａはダルマ１３Ａと噛合しているので、前記スライダ板６１ｂによも先行移動して、その押圧部でもってストッパレバー６２を若干回転させ、そのロック状態を解く（図１５参照）。このロック状態を解くまでスライダ板６１ｂはストッパレバー６２により係止されているので、そのまま解錠位置に取り残されている。そこで、回転中のダルマ１３Ａ（駆動カム）の係合アーム１３ａの折曲先端部の内側がスライダ板６１ｂの後端部側の受け部分に当接するように衝突する。そして、このまま摺動部材６１を後押しながら（動力源としての付勢手段の付勢力を追随的にサポートしながら）施錠方向へダルマ１３Ａと共働しながら位置変位していく。 In the above configuration, the sliding member 61 of the lock X2 includes at least a rack plate 61a meshing with the dharma 13A and a slider plate 61b engaged in a joined state so as to cooperate with the rack plate. In the initial operation when the dharma 13A starts to rotate, the rack plate 61a meshes with the dharma 13A, so that the slider plate 61b moves in advance, and the stopper lever 62 is slightly rotated by the pressing portion. Then, the locked state is released (see FIG. 15). Since the slider plate 61b is locked by the stopper lever 62 until the locked state is released, it remains in the unlocked position as it is. Therefore, the inner side of the bent leading end portion of the engaging arm 13a of the rotating dharma 13A (driving cam) collides with the receiving portion on the rear end side of the slider plate 61b. Then, the position of the sliding member 61 is displaced while cooperating with the dharma 13A in the locking direction while pushing the sliding member 61 as it is (followingly supporting the urging force of the urging means as a power source).

この第７実施形態の特徴事項は、（ａ）デッドボルト１４を施錠方向へ突出させる動力源として「駆動バネ７０」を用いた点、（ｂ）検出装置の一例として第２実施形態と同一の検出装置Ｙ１を用いた点である。このように、本発明の主要部を構成する検出装置は、電気錠又は／及び機械式錠前のいずれにも適用することができる。 The features of the seventh embodiment are (a) the point that the “drive spring 70” is used as a power source for projecting the dead bolt 14 in the locking direction, and (b) the same as the second embodiment as an example of the detection device. This is a point using the detection device Y1. As described above, the detection device constituting the main part of the present invention can be applied to either an electric lock or / and a mechanical lock.
