Description

本発明は、錠前に関し、例えば電気錠にも適用することができる錠前に関する。 The present invention relates to a lock, about the lock which can be applied to, for example, an electric lock.

特許文献１には、住宅用の電気錠システムの一例が記載されている。その図３には、モード切換えスイッチ１６、１８等を制御器６に設ける事項が記載されている。すなわち、特許文献１には、「…室内の内壁面に設置される制御器６の操作パネル１１に、扉を開けっ放し状態に表示するドアランプ１５と、扉側の錠前を連続解錠状態と連続施錠状態に切換えるスイッチ１６、扉側の錠前を一時解錠状態にするスイッチ１８等に設ける事項…」が記載されている（符号は特許文献のもの）。 Patent Document 1, an example of electric Kijo systems for residential are described. FIG. 3 shows matters for providing the mode changeover switches 16, 18 and the like in the controller 6. That is, Patent Document 1 states that “... the door lamp 15 that displays the door in an open state on the operation panel 11 of the controller 6 installed on the inner wall surface of the room, and the door side lock is continuously unlocked and continuously locked. The switch 16 for switching to the state, the matter provided in the switch 18 for temporarily locking the lock on the door side, etc. ”are described (the reference numerals are those of patent documents).

上記構成に於いて、連続施錠状態に切換えるスイッチ１６、一時解錠状態にするスイッチ１８等は、扉側ではなく、室内の内壁面の適宜箇所に設置される制御器６、具体的にはその前面の操作パネル１１に設けるので、扉に設置した電気錠から離れた場所（例えば室内の壁面）であっても、電気錠のモードを切換えることができるという利点がある。
しかしながら、この特許文献１には、操作パネル１１に複数個の切換えスイッチ（複数個の操作ボタン）をそれぞれ配設する必要があると共に、各切換えるスイッチと制御器６の制御回路とを複数個の端子を介してそれぞれ接続しなければならないという問題点がある。なお、特許文献１には、錠箱自体に機械的にモード切換える機構を配設する事項は記載されていない。 In the above configuration, the switch 16 for switching to the continuous locking state, the switch 18 for temporarily releasing the locking state, etc. are not the door side but the controller 6 installed at an appropriate place on the inner wall surface of the room, specifically, Since it is provided on the operation panel 11 on the front surface, there is an advantage that the mode of the electric lock can be switched even at a place away from the electric lock installed on the door (for example, a wall surface in the room).
However, in Patent Document 1, it is necessary to dispose a plurality of changeover switches (a plurality of operation buttons) on the operation panel 11, and each of the changeover switches and the control circuit of the controller 6 includes a plurality of switches. There is a problem that each must be connected via a terminal. Note that Patent Document 1 does not describe matters for disposing a mechanical mode switching mechanism in the lock box itself.

次に、１２は錠箱４の略中央部に水平状態に設けられたトリガーで、紙面上、このトリガー１２の裏側に本願発明を構成するモード切換え用入力手段３１が併設状態に存在する。トリガー１２及びモード切換え用入力手段３１の下方に所要の空間を有してデッドボルト（以下、ここでは「デッド」の用語を用いる）１４が出没自在の配設されている。 Next, reference numeral 12 denotes a trigger provided in a horizontal state at a substantially central portion of the lock box 4. On the paper surface, a mode switching input means 31 constituting the present invention is present on the back side of the trigger 12 in a side-by-side state. A dead bolt (hereinafter, the term “dead” is used) 14 is provided so as to be able to appear and retract, having a required space below the trigger 12 and the mode switching input means 31.

電気錠Ｘの錠箱４内の所要空間には、デッド１４を錠箱４内に後退させた状態を保持する解錠状態保持機構１５が配設され、該解錠状態保持機構１５は、少なくともデッド１４の没入状態を保持する摺動部材１６と、該摺動部材用のストッパレバー１７から成る。 In the required space in the lock box 4 of the electric lock X, an unlocked state holding mechanism 15 for holding the state in which the dead 14 is retracted into the lock box 4 is disposed, and the unlocked state holding mechanism 15 includes at least It comprises a sliding member 16 that keeps the dead 14 immersed, and a stopper lever 17 for the sliding member.

しかして、前記摺動部材用のストッパレバー１７は、前述したトリガー１２の後端部に係合するように上方に伸長する第１係合腕１７ａ、摺動部材１６のピン状被係合部１６ａにその先端部が係脱する斜め方向第２係合腕１７ｂ、錠箱４の後壁側に配設したバネ部材１８の一端部を受ける斜め方向バネ受け腕１７ｃ等をそれぞれ有し、かつ、固定軸１９に軸支されている。 Thus, the stopper lever 17 for the sliding member includes a first engaging arm 17a extending upward so as to engage with the rear end portion of the trigger 12, and the pin-like engaged portion of the sliding member 16. 16a has an oblique second engagement arm 17b whose tip is engaged and disengaged, an oblique spring receiving arm 17c for receiving one end of a spring member 18 disposed on the rear wall side of the lock box 4, and the like. The shaft is supported by a fixed shaft 19.

また、前記摺動部材１６は、下辺部にダルマ２１に噛合するラック２０を有し、図示しない案内手段を介して斜め方向に往復動可能である。２３はダルマ２１の近傍に配設された施錠用の動力源としての付勢手段で、該動力源２３は錠箱側に一端部が取付けられ、一方、他端部がダルマ２１に取付けられている。動力源２３は、例えば捩じりコイルバネ２３ａと、該捩じりコイルバネの螺旋状中央部を横柱で支持する可動のバネガイド２３ｂとから成る。 The sliding member 16 has a rack 20 that meshes with the dharma 21 on the lower side, and can reciprocate in an oblique direction via a guide means (not shown). Reference numeral 23 denotes an urging means as a power source for locking disposed in the vicinity of the dharma 21. The power source 23 has one end attached to the lock box side and the other end attached to the dharma 21. Yes. The power source 23 includes, for example, a torsion coil spring 23a and a movable spring guide 23b that supports a spiral central portion of the torsion coil spring with a horizontal column.

次に、ダルマ２１とデッド１４には、駆動リンク２４、作動アーム２５及びデッド用ストッパ２６が介在している。すなわち、本実施例では、前記駆動リンク２４の両端部は、ダルマ２１及びデッド１４にそれぞれ連結され、また、前記作動アーム２５の上端部はダルマ２１に枢支され、一方、該作動アーム２５の下端部は、錠箱１側に設けられた案内切欠部２７に案内される横杆状のデッド用ストッパ２６が取付けられている。そして、前記デッド用ストッパ２６は、前記デッド４が付勢手段２３の付勢力によって完全に突出した自動施錠モード時には、前記案内切欠部２７に案内されてデッド１４の後端面をロックする。周知のように、ダルマ２１は、駆動モータ１０の駆動力、図示しないシリンダー装置、サムターン装置等の機械的操作手段の操作力（合鍵の操作力、サムター摘みの操作力）により回動する。 Next, a drive link 24, an operating arm 25, and a dead stopper 26 are interposed between the dharma 21 and the dead 14. That is, in this embodiment, both end portions of the drive link 24 are connected to the dharma 21 and the dead 14, respectively, and the upper end portion of the operating arm 25 is pivotally supported by the dharma 21. At the lower end, a recumbent dead stopper 26 guided by a guide notch 27 provided on the lock box 1 side is attached. The dead stopper 26 is guided by the guide notch 27 to lock the rear end surface of the dead 14 in the automatic locking mode in which the dead 4 is completely projected by the urging force of the urging means 23. As is well known, the dharma 21 is rotated by the driving force of the driving motor 10, the operating force of a mechanical operating means such as a cylinder device (not shown), the thumb turn device, etc. (the operating force of the key lock, the operating force of the thumb picking).

次に、図１は、本発明の実施例が、該トリガー１２に対して併設されかつフロント板４ａの開口９に対して進退動可能な入力手段（例えば操作板）３１と、該入力手段と錠箱４の内壁面側に設けられていると共に該入力手段を自動施錠モードの位置と連続解錠モードの位置にそれぞれ繰り返して停止させるモード切換え手段４９と、デッドボルト１４を錠箱内に後退させた状態を保持する解錠状態保持機構１５と、デッド突出用の動力源２３と、この動力源の駆動力で施錠方向へ回転するダルマ２１と、該ダルマを介して機械的に出没するデッド１４を備えていることを示している。 Next, FIG. 1 shows an embodiment of the present invention in which an input means (for example, an operation plate) 31 that is provided with the trigger 12 and can be moved back and forth with respect to the opening 9 of the front plate 4a, A mode switching means 49 which is provided on the inner wall surface side of the lock box 4 and repeatedly stops the input means at the position of the automatic lock mode and the position of the continuous unlock mode, and the dead bolt 14 is retracted into the lock box. An unlocked state holding mechanism 15 for holding the released state, a power source 23 for dead protrusion, a dharma 21 that rotates in the locking direction by the driving force of the power source, and a dead that mechanically appears and disappears through the dharma 14 is provided.

しかして、本発明の実施例にあっては、（ａ）前記入力手段３１が開口９を介して指で押し込まれ、例えば連続解錠モードの位置にある場合には、前記解錠状態保持機構１５は、前記入力手段３１に連動する連動部材を介してトリガー１２に連動しないようにし、（ｂ）一方、前記入力手段３１が自動施錠モードの位置にある場合には、前記解錠状態保持機構１５は、前記入力手段に連動する連動部材を介してトリガー１２に連動し、デッド１４を錠箱内に後退させた状態を解消し、該デッドは前記動力源の駆動力で施錠方向へと突出する。なお、前記連動部材は、単数又は複数の係合片を組み合わせることにより、前記解錠状態保持機構１５を構成する摺動部材用のストッパレバー１７を作動させたり、或いはトリガー１２をロックしたり、そのロックを解消させたりしている。 Thus, in the embodiment of the present invention, (a) when the input means 31 is pushed in with a finger through the opening 9 and is in the position of the continuous unlocking mode, for example, the unlocked state holding mechanism 15 is configured not to be interlocked with the trigger 12 via an interlocking member interlocked with the input means 31. (b) On the other hand, when the input means 31 is in the automatic locking mode position, the unlocking state holding mechanism 15 is interlocked with the trigger 12 via an interlocking member that is interlocked with the input means to eliminate the state in which the dead 14 is retracted into the lock box, and the dead protrudes in the locking direction by the driving force of the power source. To do. In addition, the interlocking member operates the stopper lever 17 for the sliding member constituting the unlocked state holding mechanism 15 by combining one or a plurality of engagement pieces, or locks the trigger 12, The lock is released.

付言すると、入力手段３１が自動施錠モードの位置にある場合には、例えば扉３を閉じると、トリガー１２が作動（後退）して、解錠状態保持機構１５のストッパレバー１７がデッド１４の保持状態を解く方向へと回転し、その後、ダルマ２１は付勢手段２３の付勢力により自動的に施錠方向へと回動して、仮想線で示したデッド１４が受け金具２に係入する（自動施錠）。この場合、図１４で示すように、摺動部材用のストッパレバー１７の第２係合腕１７ｂが、傾斜方向にスライド可能な摺動部材１６の被係合部１６ａから外れる。これに対して、入力手段が「自動施錠モード」から「連続解錠モード」へと切換わり、連続解錠モードの位置にある場合には（この場合、錠前が電気錠である場合には、電気錠制御部は、例えばモード切換え確認用スイッチ３３を介して、連続解錠信号を取得する。）図１５で示すように、摺動部材用のストッパレバー１７の第２係合腕１７ｂは、摺動部材１６の被係合部１６ａを係止している。 In addition, when the input means 31 is in the automatic locking mode position, for example, when the door 3 is closed, the trigger 12 is activated (retracted), and the stopper lever 17 of the unlocked state holding mechanism 15 holds the dead 14. Then, the Dharma 21 is automatically rotated in the locking direction by the urging force of the urging means 23, and the dead 14 indicated by the phantom line is engaged with the receiving metal fitting 2 ( Automatic locking). In this case, as shown in FIG. 14, the second engagement arm 17b of the stopper lever 17 for the sliding member is disengaged from the engaged portion 16a of the sliding member 16 that can slide in the tilt direction. On the other hand, when the input means is switched from the “automatic locking mode” to the “continuous unlocking mode” and is in the position of the continuous unlocking mode (in this case, when the lock is an electric lock, The electric lock control unit obtains a continuous unlocking signal, for example, via the mode switching confirmation switch 33.) As shown in FIG. 15, the second engagement arm 17b of the stopper lever 17 for the sliding member is The engaged portion 16a of the sliding member 16 is locked.

したがって、摺動部材１６、該摺動部材のラック２０に噛合するダルマ２１及びデッド１４は、それぞれ解錠の位置にあり、前記係合腕１７ａが前記被係合部１６ａから外れない限り（図１４の矢印Ｂ方向へストッパレバー１７が回転しない限り）、デッド１４が錠箱４内に引っ込んだ状態が続く。そこで、本発明の錠前について、電気錠システムを参照にして説明する。 Therefore, the sliding member 16, the dharma 21 that meshes with the rack 20 of the sliding member, and the dead 14 are each in the unlocked position, so long as the engaging arm 17a is not disengaged from the engaged portion 16a (see FIG. As long as the stopper lever 17 does not rotate in the direction of arrow B of 14), the state in which the dead 14 is retracted into the lock box 4 continues. Therefore, the lock of the present invention will be described with reference to an electric lock system.

（２）電気錠システムの概念図
図２は電気錠システムの概念図である。図に於いて、３１は手動操作で位置変位するモード切換え用の入力手段（操作板）で、該モード切換え用の入力手段３１は後述のモード切換え手段（例えばクリック手段を構成するクリックピンと、該クリックピンの先端部と係合する摺動カム）４９を備えている。３２は、この第１実施例では、主に、信号取得用連動部材で、図７で示すように、該信号取得用連動部材３２はモード切換え用入力手段３１と共働することができるようにその先端部が錠箱４に軸支されていると共に、その被係合部（あるいは係合部）が、前記モード切換え用入力手段３１の係合部（或いは被係合部）と係合し、かつ、モード切換え用入力手段３１がフロント板側から押し込まれると、該モード切換え用入力手段３１に連動して位置変位する（図１３参照）。 (2) Conceptual diagram of the electric lock system FIG. 2 is a conceptual diagram of the electric lock system. In the figure, reference numeral 31 denotes a mode switching input means (operation plate) that is displaced by manual operation. The mode switching input means 31 is a mode switching means described later (for example, a click pin constituting a click means, (Sliding cam 49) engaged with the tip of the click pin. In this first embodiment, reference numeral 32 is mainly a signal acquisition interlocking member. As shown in FIG. 7, the signal acquisition interlocking member 32 can cooperate with the mode switching input means 31. The tip portion is pivotally supported by the lock box 4 and the engaged portion (or engaging portion) is engaged with the engaging portion (or engaged portion) of the mode switching input means 31. When the mode switching input means 31 is pushed in from the front plate side, the position is displaced in conjunction with the mode switching input means 31 (see FIG. 13).

３３は単数又は複数のモード切換え確認用スイッチで、例えば可動接片を有するマイクロスイッチが用いられている。なお、このモード切換え確認用スイッチ３３は、必ずしも、信号取得用連動部材３２に対して配設する必要はなく、入力手段３１に対して配設しても良い。望ましくは、入力手段３１に突片状の遮蔽部３９を設け（図５参照）、一方、モード切換え確認用スイッチ３３、自動施錠モードの位置と連続解錠モードの位置をそれぞれ検出する図示しない光センサー型の検出手段等を錠箱４内に複数個を適宜配設する。 Reference numeral 33 denotes one or a plurality of mode switching confirmation switches, for example, microswitches having movable contact pieces. The mode switching confirmation switch 33 is not necessarily provided for the signal acquisition interlocking member 32 but may be provided for the input unit 31. Desirably, the input means 31 is provided with a projecting piece-shaped shielding part 39 (see FIG. 5), while the mode switching confirmation switch 33, a light not shown for detecting the position of the automatic locking mode and the position of the continuous unlocking mode, respectively. A plurality of sensor-type detection means and the like are appropriately arranged in the lock box 4.

６は外制御部及び電気錠制御用プリント基板８とから成る制御部、５は電源、１０乃至２７は駆動モータ１０、動力伝達手段１１、トリガー１２等の電気錠Ｘを構成する主な構成部材、２８は錠箱内の適宜箇所に配設された複数固の検知器、２９は前記モード切換え確認用スイッチ３３以外の扉、壁等に配設された解除信号発生手段、３０は表示手段である。 6 is a control unit comprising an external control unit and an electric lock control printed circuit board 5, 5 is a power source, 10 to 27 are main components constituting the electric lock X, such as a drive motor 10, a power transmission means 11, and a trigger 12. , 28 are a plurality of solid detectors disposed at appropriate positions in the lock box, 29 is a release signal generating means disposed on a door, wall or the like other than the mode switching confirmation switch 33, and 30 is a display means. is there.

入力手段３１は、図３で示すように、長板状の摺動体であり、錠箱４のフロント板４ａに形成した開口９に、その先端部が位置し、或いは臨むようにトリガー１２と共に併設されている。図４で示すように信号取得用連動部材３２は、モード切換え用入力手段３１に連動して位置変位、例えば時計方向又は反時計方向に回転すると、モード切換え確認用スイッチ３３の可動接片を押圧し、その押圧状態を保持する共働片である。 As shown in FIG. 3, the input means 31 is a long plate-like sliding body, and is provided together with the trigger 12 so that the tip thereof is positioned or faces the opening 9 formed in the front plate 4 a of the lock box 4. Has been. As shown in FIG. 4, when the signal acquisition interlocking member 32 is rotated in position, for example, clockwise or counterclockwise, in conjunction with the mode switching input means 31, the movable contact piece of the mode switching confirmation switch 33 is pressed. And it is a cooperating piece that holds the pressed state.

ところで、電気錠Ｘの施・解錠状態に関する「状態信号」は、例えば連続解錠状態、連続施錠状態、一時施錠、一時解錠の「４つ」が存在するので、モード切換え用入力手段３１は、理論上、そのいずれか一つに切換えるように構成することもできる。しかしながら、本実施例では、少なくとも機械的に「自動施錠モードの位置」又は「連続解錠モードの位置」のいずれか一つに切換えることができれば良い。もちろん、前記２つの態様に「連続施錠状態」を加味しても良い。 By the way, since the “status signal” regarding the locking / unlocking state of the electric lock X includes, for example, “four” of continuous unlocking state, continuous locking state, temporary locking, and temporary unlocking, the mode switching input means 31. Theoretically, it can be configured to switch to any one of them. However, in this embodiment, it is only necessary that at least one of the “position in the automatic locking mode” and the “position in the continuous unlocking mode” can be mechanically switched. Of course, “continuous locking state” may be added to the two modes.

制御部６は、例えば商用交流電圧を直流に変換する電源回路や電池を含む電源５と接続し、各種の信号を処理する。検知手段２８は閉扉信号や開扉信号を取得するものである。解除信号発生手段２９は、テンキー、リモコンキー、カード読取り器などであり、接触又は非接触方式で電気錠Ｘを室外から解錠することができる。表示手段３０はランプの点灯または消灯に基づいて、連続解錠状態、連続施錠状態、一時解錠状態、扉の開けっ放し状態等を視覚により識別するためのものである。 The control unit 6 is connected to, for example, a power supply circuit that converts a commercial AC voltage into direct current or a power supply 5 including a battery, and processes various signals. The detection means 28 acquires a closing signal or an opening signal. The release signal generation means 29 is a numeric keypad, a remote control key, a card reader or the like, and can unlock the electric lock X from the outside in a contact or non-contact manner. The display means 30 is for visually identifying the continuous unlocking state, the continuous locking state, the temporary unlocking state, the door open state, and the like based on whether the lamp is turned on or off.

（３）本発明の主要部
図３は、入力手段３１とトリガー１２とが併設された状態の斜視図である。手前がケース状先端部を有するトリガー１２で、この裏側にやや長板状のモード切換え用入力手段３１が位置している。トリガー１２と入力手段３１は別個の部材であり、トリガー１２はケース状先端部に図示しない磁性体を有し、閉扉時、例えば戸枠側の磁性体の極性に対応して錠箱内へ若干後退動することができる。また、入力手段３１とトリガー１２は別個の部材であるから、入力手段３１のみを単独で押し込むことができる。 (3) Main Part of the Present Invention FIG. 3 is a perspective view showing a state where the input unit 31 and the trigger 12 are provided side by side. The front side is a trigger 12 having a case-like tip, and a mode switch input means 31 having a slightly long plate shape is located on the back side. The trigger 12 and the input means 31 are separate members, and the trigger 12 has a magnetic body (not shown) at the case-shaped front end portion. When the door is closed, for example, the trigger 12 slightly enters the lock box according to the polarity of the magnetic body on the door frame side. Can move backwards. Moreover, since the input means 31 and the trigger 12 are separate members, only the input means 31 can be pushed alone.

図４は図３で示したトリガー１２を省略し、本発明の要部を示す概略説明図である。図４は、例えば自動施錠モードの一例である。図に於いて、９はフロント板４ａに形成された開口で、入力手段３１は、その先端部３１ａが該開口９を臨むように或いは開口９に位置するように配設されている。付言すると、モード切換え用入力手段３１は、錠箱４のフロント板４ａに形成した開口９に対して水平動自在に配設されている。入力手段３１の右上方には、錠箱４側の固定ピン３５に復帰バネ３６が設けられ、該復帰バネ３６は入力手段３１をフロント板４ａの開口９側に常に付勢している。したがって、入力手段３１の先端部を、開口９を介して指で押し込むと、該入力手段３１は復帰バネ３６のバネ力に抗して所定位置まで後退し、モード切換え手段４９により一時停止する。 FIG. 4 is a schematic explanatory view showing the main part of the present invention, omitting the trigger 12 shown in FIG. FIG. 4 is an example of an automatic locking mode, for example. In the figure, reference numeral 9 denotes an opening formed in the front plate 4a, and the input means 31 is disposed so that the tip 31a faces the opening 9 or is positioned in the opening 9. In addition, the mode switching input means 31 is disposed so as to be horizontally movable with respect to the opening 9 formed in the front plate 4 a of the lock box 4. On the upper right side of the input means 31, a return spring 36 is provided on the fixing pin 35 on the lock box 4 side, and the return spring 36 always urges the input means 31 toward the opening 9 of the front plate 4a. Therefore, when the tip of the input means 31 is pushed in with a finger through the opening 9, the input means 31 moves back to a predetermined position against the spring force of the return spring 36 and is temporarily stopped by the mode switching means 49.

図５は入力手段３１と、モード切換え手段４９の一方を構成する摺動カム５０とを示す斜視図である。摺動カム５０はこの入力手段３１の案内部に組み込まれ、紙面上、上下方向に自在に移動可能である。図６は入力手段３１と復帰バネ３６の組み合わせを示す概略説明図である。これらの図に於いて、３１ａは入力手段３１の先端部で、該先端部にはやや小片状の押圧部３７が設けられている。この押圧部３７を図示しない指で押し込むと、入力手段３１は復帰バネ３６のバネ力に抗して位置変位する。なお、入力手段３１を押し込む際に、前記押圧部３７がトリガー１２の先端部に当たらないように、例えばトリガー１２の対向側壁には図示しない切欠凹所が形成されている。 FIG. 5 is a perspective view showing the input means 31 and the sliding cam 50 constituting one of the mode switching means 49. The sliding cam 50 is incorporated in the guide portion of the input means 31 and can freely move in the vertical direction on the paper surface. FIG. 6 is a schematic explanatory view showing a combination of the input means 31 and the return spring 36. In these drawings, reference numeral 31a denotes a tip portion of the input means 31, and a slightly small pressing portion 37 is provided at the tip portion. When the pressing portion 37 is pushed with a finger (not shown), the input means 31 is displaced against the spring force of the return spring 36. For example, a notch recess (not shown) is formed on the opposing side wall of the trigger 12 so that the pressing portion 37 does not hit the tip of the trigger 12 when the input means 31 is pushed.

３８は中央部（先端部寄りの部位も含む）に形成された開口又は凹所状の案内部で、本実施例では、該案内部３８は矩形状の開口である。この開口部３８の左右対向内面に上下方向に一対のガイドレール３８ａ、３８ａが形成されている。矩形板状の摺動カム５０は、前記案内部３８に上下方向に移動可能に組み込まれる。３９は、入力手段３１の上辺の中央部に突設された突片部分で、この突片部分３９の先端部は、前述したように、図示しない光センサー型検出手段、磁気感応型検出手段等の遮蔽部（或いは磁気部）と成っている。 Reference numeral 38 denotes an opening or a recessed guide formed at the center (including a portion near the tip). In this embodiment, the guide 38 is a rectangular opening. A pair of guide rails 38a, 38a are formed on the left and right inner surfaces of the opening 38 in the vertical direction. A rectangular plate-shaped sliding cam 50 is incorporated in the guide portion 38 so as to be movable in the vertical direction. 39 is a projecting piece projecting from the center of the upper side of the input means 31, and the tip of the projecting piece 39 is, as described above, an optical sensor type detecting means, a magnetic sensitive detecting means, etc., not shown. The shielding part (or magnetic part).

４０は突片部分３９よりも後方側に設けられたピン状の係合部で、本実施例では入力手段３１の上端部の適宜箇所から水平状態に突出している。４１は入力手段３１の裏面に突設されたバネ受けである。図６で示すように、復帰バネ３６は開きバネが使用され、その中央部は固定ピン３５に巻装され、一端部３６ａは前記バネ受け４１に支持されていると共に、その他端部３６ｂは錠箱側に設けられた突起４２に支持されている。したがって、入力手段３１は復帰バネ３６のバネ力が開口９側に作用するように錠箱４内にスライド可能に設けられ、前記開口９を介して押圧されると、後述のモード切換え手段（摺動カム、クリックピン、クリックバネ）４９を介して選択的に所定位置にて停止する。 Reference numeral 40 denotes a pin-like engaging portion provided on the rear side of the projecting piece portion 39, which protrudes in a horizontal state from an appropriate portion of the upper end portion of the input means 31 in this embodiment. Reference numeral 41 denotes a spring receiver protruding from the back surface of the input means 31. As shown in FIG. 6, an opening spring is used as the return spring 36, its central portion is wound around the fixing pin 35, one end portion 36a is supported by the spring receiver 41, and the other end portion 36b is locked. It is supported by a protrusion 42 provided on the box side. Therefore, the input means 31 is slidably provided in the lock box 4 so that the spring force of the return spring 36 acts on the opening 9 side. (Moving cam, click pin, click spring) 49 and selectively stops at a predetermined position.

図７は入力手段３１に連動する信号取得用連動部材３２の説明図である。この連動部材３２は、第１実施例では、例えばモードが切り換わったか否かを確実に知るために用いられている。もちろん、この連動部材３２をトリガー１２用のロック片やトリガー１２からの入力を切断するための係合片に関連付けることもできる（第２実施例）。ここでは、主に信号取得用に関連付けられている。 FIG. 7 is an explanatory view of the signal acquisition interlocking member 32 interlocking with the input means 31. In the first embodiment, the interlocking member 32 is used for surely knowing whether or not the mode has been switched, for example. Of course, the interlocking member 32 can be associated with a lock piece for the trigger 12 or an engagement piece for cutting off the input from the trigger 12 (second embodiment). Here, it is mainly associated with signal acquisition.

さて、信号取得用連動部材３２は、錠箱４のケース蓋４ｃの内壁面に設けられた横軸４４に軸支され、かつ、入力手段３１のピン状係合部４０に溝状の被係合部分を介して係合している。しかして、信号取得用連動部材３２の形態は特に問わないが、例えば先端部に錠箱側の横軸４４に外嵌合する筒状嵌合部４５を有すると共に、該筒状嵌合部４５に腕状の押圧部兼用被案内部４６が連設している。前記押圧部兼用被案内部４６の連設部分の上面はやや傾斜状の押圧面４６ａとなっており、この傾斜状押圧面４６ａはモード切換え確認スイッチ３３の可動接片３３ａに接触する。また、連設部分の一側面には水平状態から下り坂状に連設する溝状の被案内部分４６ｂが形成され、該溝状被案内部分４６ｂに入力手段のピン状係合部４０が係合する。 Now, the signal acquisition interlocking member 32 is pivotally supported by a horizontal shaft 44 provided on the inner wall surface of the case lid 4c of the lock box 4, and is engaged with the pin-like engagement portion 40 of the input means 31 in the form of a groove. It is engaged through the joint part. Thus, the form of the signal acquisition interlocking member 32 is not particularly limited. For example, the distal end portion has a cylindrical fitting portion 45 that is fitted to the horizontal shaft 44 on the lock box side, and the cylindrical fitting portion 45. The arm-shaped pressing portion / guided portion 46 is continuously provided. The upper surface of the continuous portion of the pressing portion / guided portion 46 is a slightly inclined pressing surface 46 a, and the inclined pressing surface 46 a contacts the movable contact piece 33 a of the mode switching confirmation switch 33. In addition, a groove-shaped guided portion 46b is provided on one side surface of the continuous portion so as to extend downwardly from the horizontal state, and the pin-shaped engaging portion 40 of the input means is engaged with the groove-shaped guided portion 46b. Match.

したがって、信号取得用連動部材３２は入力手段に連動するように錠箱に軸支されていると共に、位置変位すると、モード切換えスイッチ３３の可動接片３３ａを押圧する。このように信号取得用連動部材３２が位置変位すると、モード切換え確認スイッチ３３は、「自動施錠モードの位置」か、それとも「連続解除モードの位置」のいずれかに切換わったことを検出し、該確認信号は制御部６，７に送られる。 Accordingly, the signal acquisition interlocking member 32 is pivotally supported by the lock box so as to interlock with the input means, and when the position is displaced, the movable contact piece 33a of the mode changeover switch 33 is pressed. When the signal acquisition interlocking member 32 is displaced as described above, the mode change confirmation switch 33 detects that the position has been changed to either “automatic locking mode position” or “continuous release mode position”. The confirmation signal is sent to the control units 6 and 7.

次に、図８乃至図１１を参照にして、入力手段３１を所定位置に選択的に停止させるモード切換え手段（例えばクリック手段）４９を説明する。図８はモード切換え手段４９の分解斜視図である。この図から明らかなように、モード切換え手段４９は、入力手段３１の案内部３８に摺動自在に組み込まれる矩形状の摺動カム５０と、この摺動カム５０の一側面に形成された一連のガイド溝５１にその係合端部５２ａが係合するクリックピン５２と、このクリックピンを常に係合方向へと付勢するクリックバネ５３とから成り、前記クリックピン５２の他端部５２ｂは、クリックバネ５３に付勢された状態で錠箱４側の固定案内部或いは固定案内部材５４に嵌合している。 Next, a mode switching means (for example, click means) 49 for selectively stopping the input means 31 at a predetermined position will be described with reference to FIGS. FIG. 8 is an exploded perspective view of the mode switching means 49. As is apparent from this figure, the mode switching means 49 includes a rectangular sliding cam 50 slidably incorporated in the guide portion 38 of the input means 31 and a series formed on one side surface of the sliding cam 50. A click pin 52 with which the engagement end 52a engages with the guide groove 51, and a click spring 53 that constantly urges the click pin in the engagement direction. The other end 52b of the click pin 52 is In the state of being urged by the click spring 53, the lock guide 4 is fitted to the fixed guide portion or the fixed guide member 54 on the lock box 4 side.

したがって、モード切換え手段４９の一方を構成する入力手段３１側の摺動カム５０は、入力手段３１と共に矢印で示す方向へ位置変位可能であるのに対して、モード切換え手段４９の他方を構成するクリックピン５２及びクリックバネ５３は錠箱４側の固定案内部５４に摺動カム５０と一緒に移動しないように位置付けられ、摺動カム５０のガイド溝５１に形成した複数個のモード切換え用段差部にそれぞれ係止状態に係合可能である。 Therefore, the sliding cam 50 on the input means 31 side that constitutes one of the mode switching means 49 can be displaced in the direction indicated by the arrow together with the input means 31, whereas it constitutes the other of the mode switching means 49. The click pin 52 and the click spring 53 are positioned so as not to move together with the sliding cam 50 on the fixed guide portion 54 on the lock box 4 side, and a plurality of mode switching steps formed in the guide groove 51 of the sliding cam 50. Each part can be engaged in a locked state.

図９は摺動カム５０の斜視図である。また、図１０は摺動カム５０の正面視からの概略断面説明図である。さらに、図１１は摺動カム５０のガイド溝５１を展開状態で示し、かつ固定案内部５４側のクリックピン５２及びクリックバネ５３も共に示したものである。 FIG. 9 is a perspective view of the sliding cam 50. Further, FIG. 10 is a schematic cross sectional view showing a front view or these sliding cam 50. Further, FIG. 11 shows the guide groove 51 of the sliding cam 50 in an unfolded state, and also shows both the click pin 52 and the click spring 53 on the fixed guide portion 54 side.

図９で示すように、摺動カム５０は、その幅広の正面部５０ａに「挟み形状」或いは「ハート形状」のイメージを彷彿される幾何学形状のガイド溝５１が形成されている。また、摺動カム５０は前記幅広の正面部５０ａに連設する幅狭の背面部５０ｂを有し、該幅狭の背面部５０ｂと幅広の正面部５０ａの左右のＬ形状の段差部分が入力手段３１の案内部３８のガイドレール３８ａ、３８ａに案内される。したがって、本実施例では、入力手段３１が水平方向に移動すると、摺動カム５０は、前記案内部３８に案内されて入力手段３１に直交する垂直方向へと移動可能である。 As shown in FIG. 9, the sliding cam 50 has a geometrical guide groove 51 formed on the wide front portion 50 a thereof that has a “sandwich” or “heart shape” image. Further, the sliding cam 50 has a narrow back surface portion 50b connected to the wide front surface portion 50a, and left and right L-shaped step portions of the narrow back surface portion 50b and the wide front surface portion 50a are input. It is guided to the guide rails 38a, 38a of the guide part 38 of the means 31. Therefore, in this embodiment, when the input means 31 moves in the horizontal direction, the sliding cam 50 is guided by the guide portion 38 and can move in the vertical direction perpendicular to the input means 31.

図１０は、ガイド溝５１を判り易く示した概略断面説明図である。この図に於いて、溝の浅い所、深い所、傾斜面、ストッパ面等を容易に理解することはできないが、それらは図１１を参照にして理解することができる。 FIG. 10 is a schematic cross-sectional explanatory view showing the guide groove 51 in an easily understandable manner. In this figure, the shallow part, deep part, inclined surface, stopper surface, etc. of the groove cannot be easily understood, but they can be understood with reference to FIG.

ここで図１０を参照にして、クリックピン５２の位置を説明する。なお、図面上、クリックピン５２が一連のガイド溝５１内を一方向へと循環移動するように見えるが、これは説明の便宜上のもので、クリックピン５２は所定位置にあり、実際は、摺動カム５０の方が入力手段３１と共働して上下左右に位置変位する。 Here, the position of the click pin 52 will be described with reference to FIG. In the drawing, the click pin 52 appears to circulate in one direction in the series of guide grooves 51. However, this is for convenience of explanation, and the click pin 52 is in a predetermined position. The cam 50 cooperates with the input means 31 and is displaced vertically and horizontally.

さて、一連のガイド溝５１には、少なくとも「１つのモード用係止段部５１ａ」と「他のモード用係止段部５１ｂ」が存在する。本実施例では、「１つのモード用係止段部」は自動施錠モード用係止段部５１ａであり、一方、「他のモード用係止段部」は連続解除モード用係止段部５１ｂである。前述したように入力手段３１には復帰バネ３６のバネ力が常に紙面上矢印で示す左方向に作用していることから、例えば仮に一連のガイド溝５１の先端部に相当する山形状或いは弧状の第１係止面（ストッパ面）５５を有する段差部分を自動施錠モード用係止段部５１ａであるとすれば、断面で示したクリックピン５２は前記第１係止面５５に係止状態で係合する。 The series of guide grooves 51 includes at least “one mode locking step portion 51a” and “other mode locking step portion 51b”. In this embodiment, the “one mode locking step” is the automatic locking mode locking step 51a, while the “other mode locking step” is the continuous release mode locking step 51b. It is. As described above, since the spring force of the return spring 36 always acts on the input means 31 in the left direction indicated by the arrow on the drawing, for example, a mountain shape or an arc shape corresponding to the tip of the series of guide grooves 51 is assumed. If the stepped portion having the first locking surface (stopper surface) 55 is the locking step 51a for the automatic locking mode, the click pin 52 shown in cross section is locked to the first locking surface 55. Engage.

これに対して、一連のガイド溝５１の中央部に相当する山形状或いは弧状の第２係止面（ストッパ面）５６を有する段差部分を連続解除モード用係止段部５１ｂであるとすれば、入力手段３１と共働して所定方向へと位置変位した摺動カム５０は、前記第２係止面５６に係止状態で係合する。このように一連のガイド溝５１を介して摺動カム５０が移動すると、モード切換え手段を構成するクリックピン５２の係合端部５２ａと、これに係止されるガイド溝５１の複数個のモード用係止段部５１ａ、５１ｂとが入れ替わる。 On the other hand, if the step portion having the mountain-shaped or arc-shaped second locking surface (stopper surface) 56 corresponding to the central portion of the series of guide grooves 51 is the locking step 51b for the continuous release mode. The sliding cam 50 that has been displaced in a predetermined direction in cooperation with the input means 31 engages with the second locking surface 56 in a locked state. When the sliding cam 50 moves through the series of guide grooves 51 as described above, a plurality of modes of the engagement end portion 52a of the click pin 52 constituting the mode switching means and the guide groove 51 locked to the click pin 52 are formed. The locking steps 51a and 51b are interchanged.

図１１の展開状態ガイド溝５１の詳細な説明については割愛する。この展開図に於いて、右側の平な面と、左側の平な面は同一である。つまり、左右の平らな面は自動施錠モード用係止段部５１ａである。これに対して、展開図の中央部の平らな面が、次にクリックピン５２が係止状態で停止する連続解除モード用係止段部５１ｂである。摺動カム５０や矢印で示す紙面上右側に移動すると、実線で示したクリックピン５２は、自動施錠モード用係止段部５１ａの位置からから連続解除モード用係止段部５１ｂの位置へと入れ替わる。そして、また、入力手段を操作すると、クリックピン５２は連続解除モード用係止段部５１ｂの位置から自動施錠モード用係止段部５１ａの位置へと入れ替わる。 A detailed description of the developed state guide groove 51 of FIG. 11 is omitted. In this development, the right plane and the left plane are the same. That is, the left and right flat surfaces are the locking step 51a for the automatic locking mode. On the other hand, the flat surface at the center of the developed view is the locking step 51b for the continuous release mode in which the click pin 52 stops next in the locked state. Moving to the plane on the right side indicated by the slide cam 50 and the arrow, the click pin 52 shown in solid lines, from the position of the automatic locking mode engaging step portion 51a to the position of the continuous release mode for engaging step portion 51b It is replaced with. When the input means is operated, the click pin 52 is switched from the position of the continuous release mode locking step 51b to the position of the automatic locking mode locking step 51a.

図１２は、摺動カム５０の方が入力手段３１と共働して上下左右に移動した際、クリックピン５２が、自動施錠モード用係止段部５１ａから連続解除モード用係止段部５１ｂへ、該連続解除モード用係止段部５１ｂから自動施錠モード用係止段部５１ａへと切換る旨の概略説明図である。この図１２では、クリックピン５２の軌跡が、Ａ点からＢ点、Ｂ点からＣ点、Ｃ点からＤ点、Ｄ点からＡ点へと循環移動することを示している。なお、二股状の上溝ポイントＢ点及び下溝ポイントＤ点は、モード位置がＡ点からＣ点、Ｃ点からＡ点へ切換わる際の折り返し点である。 FIG. 12 shows that when the sliding cam 50 moves up, down, left and right in cooperation with the input means 31, the click pin 52 changes from the locking step 51a for the automatic locking mode to the locking step 51b for the continuous release mode. FIG. 8 is a schematic explanatory diagram showing that the locking step 51b for the continuous release mode is switched to the locking step 51a for the automatic locking mode. FIG. 12 shows that the locus of the click pin 52 circulates from point A to point B, from point B to point C, from point C to point D, and from point D to point A. The bifurcated upper groove point B and lower groove point D are turning points when the mode position is switched from point A to point C and from point C to point A.

また、図１３の（ａ）は、自動施錠モードの検出位置、一方、図１３の（ｂ）は、連続解除モードの検出位置をそれぞれ示す。なお、例えば光センサー型検出手段、磁気感応型検出手段等の検出手段を用いる場合には、前述したように可動接片型の検出手段を必ずしも配設しなくても良い。そのような場合には、入力手段３１の遮蔽部３９に対応して、例えば発光・受光素子等を含む光センサーを配設する。このように、本実施例では、摺動カム５０の一側面には、「１つのモード用係止段部５１ａ」と「他のモード用係止段部５１ｂ」をそれぞれ有する一連のガイド溝が形成され、これらのモード用係止段部５１ａ、５１ｂに交互に入れ替わるようにクリックピン５２の係合端部５２ａが係止状態に係合し、該切換わった状態を錠箱内の適宜箇所に設けた検出手段が検知することにより、電気錠の場合には、制御部は該検出手段が検出したモード切換え確認信号を、記億部に記録する。 FIG. 13A shows the detection position in the automatic locking mode, while FIG. 13B shows the detection position in the continuous release mode. For example, when detecting means such as an optical sensor type detecting means or a magnetic sensitive type detecting means is used, the movable contact type detecting means is not necessarily provided as described above. In such a case, an optical sensor including, for example, a light emitting / receiving element or the like is disposed corresponding to the shielding part 39 of the input unit 31. Thus, in the present embodiment, a series of guide grooves each having “one mode locking step portion 51a” and “other mode locking step portion 51b” are formed on one side surface of the sliding cam 50. The engaging end portions 52a of the click pin 52 are engaged in the locked state so that they are alternately switched to these mode locking step portions 51a and 51b, and the switched state is set at an appropriate place in the lock box. In the case of an electric lock, the control unit records the mode switching confirmation signal detected by the detection unit in the storage unit.

（４）解錠状態保持機構１５
解錠状態保持機構１５は、少なくともデッド１４の没入状態を保持する摺動部材１６と、該摺動部材用のストッパレバー１７から成る。閉扉時、図１４で示すように、トリガー１２が矢印Ａの方向へ後退動し、前記ストッパレバー１７が該トリガー１２に連動して矢印Ｂ方向回転すると、その第２係合腕１７ｂが摺動部材１６の被係合部１６ａから離れ、その結果、デッド１４は付勢手段２３の付勢力により錠箱４から完全に突出した施錠状態と成る。 (4) Unlocked state holding mechanism 15
Unlocked state retaining mechanism 15 includes a slide member 16 for holding the retracted state of the dead 14 even without low, consisting stopper lever 17 for sliding member. When the door is closed, as shown in FIG. 14, when the trigger 12 moves backward in the direction of arrow A and the stopper lever 17 rotates in the direction of arrow B in conjunction with the trigger 12, the second engagement arm 17b slides. The member 16 is separated from the engaged portion 16 a of the member 16, and as a result, the dead 14 is brought into a locked state in which it is completely projected from the lock box 4 by the biasing force of the biasing means 23.

そこで、操作部材（合鍵やサムターン）の操作力又は駆動モータ１０の駆動力に基づいてダルマ２１が付勢手段２３の付勢力に抗して錠箱４内に没入した場合、摺動部材１６は、そのラック（或いはラック板）２０がダルマ２１に噛み合いながら施錠位置から解錠位置へと位置変位し、かつ位置変位した該摺動部材１６はストッパレバー１７の第２係合腕１７ｂに係止される。 Therefore, when the dharma 21 is immersed in the lock box 4 against the urging force of the urging means 23 based on the operating force of the operating member (joint key or thumb turn) or the driving force of the driving motor 10, the sliding member 16 is The rack (or rack plate) 20 is displaced from the locked position to the unlocked position while meshing with the dharma 21, and the displaced sliding member 16 is locked to the second engaging arm 17 b of the stopper lever 17. Is done.

付言すると、本実施例の解錠状態保持機構１５は、図１５で示すように、デッド１４が錠箱４内に没入した時、該デッド１４が錠箱４から飛び出ないように保持する摺動部材１６及び該摺動部材用ストッパレバー１７で構成されているので、ストッパレバー１７の先端部の第２係合腕１７ｂが摺動部材１６の被係合部１６ａから離れない限り、「連続解錠モードの状態」を維持し続ける。 In addition, as shown in FIG. 15, the unlocked state holding mechanism 15 of the present embodiment is a slide that holds the dead 14 so that it does not jump out of the lock box 4 when the dead 14 is immersed in the lock box 4. Since it is composed of the member 16 and the stopper lever 17 for the sliding member, as long as the second engaging arm 17b at the tip of the stopper lever 17 is not separated from the engaged portion 16a of the sliding member 16, the “continuous solution” Continue to maintain the “lock mode state”.

したがって、解錠時、駆動モータ１０の駆動力、閉扉時におけるトリガー１２の後退動のいずれかに基づいて、前記解錠状態保持機構１５の保持状態が解かれると（図１４の状態）、以後、ダルマ２１は動力源（付勢手段）２３の駆動力（付勢力）により自動的に施錠方向へと回動して、デッド１４が錠箱４から自動的に完全に突出することになるから、「連続解錠モードの状態」にするためには、前述したように入力手段３１を連続解錠モードの位置にする必要がある。 Therefore, Kaijoji, the driving force of the driving motor 10, based on one of the retraction of the trigger 12 during closing, when the holding state of the unlocked state retaining mechanism 15 is released (FIG. 14 state), thereafter The dharma 21 is automatically rotated in the locking direction by the driving force (biasing force) of the power source (biasing means) 23 and the dead 14 automatically protrudes completely from the lock box 4. In order to enter the “continuous unlocking mode state”, it is necessary to place the input means 31 in the continuous unlocking mode position as described above.

そこで、入力手段３１が押し込まれて連続解錠モードの位置にある場合には、解錠状態保持機構１５は、前記入力手段３１に連動する連動部材を介してトリガーに連動しないようにし、一方、前記入力手段３１が自動施錠モードの位置にある場合には、前記解錠状態保持機構１５は、前記入力手段３１に連動する連動部材を介してトリガーに連動してデッド１４を錠箱４内に後退させた状態を解消し、該デッド１４は動力源２３の駆動力で施錠方向へと突出するようにする必要がある。 Therefore, when the input means 31 is pushed in and is in the position of the continuous unlocking mode, the unlocked state holding mechanism 15 is not interlocked with the trigger via the interlocking member interlocked with the input means 31, When the input means 31 is in the automatic locking mode position, the unlocked state holding mechanism 15 causes the dead 14 to move into the lock box 4 in conjunction with a trigger via an interlocking member interlocked with the input means 31. It is necessary to eliminate the retracted state and to cause the dead 14 to protrude in the locking direction by the driving force of the power source 23.

図１６及び図１７は、モード切換え用連動部材６１が錠箱４側の固定軸６５に軸支されていると共に、係合手段６２を介して入力手段３１に連動するように組み合わせられていることを示している。 16 and 17, the mode switching interlocking member 61 is supported by the fixed shaft 65 on the lock box 4 side, and is combined so as to interlock with the input means 31 via the engaging means 62. Is shown.

まず、図１６は錠前が自動施錠モードである場合を示し、この自動施錠モードでは、トリガー１２をロックするためのモード切換え用連動部材６１の係合縁部６１ａは、トリガー１２に設けた被係合部（例えば突起）１２ａと係合していない。この第１実施例のモード切換え用連動部材６１は、トリガー１２の動きを殺すために設けられたものであるから、入力手段３１が図面上、左側（フロント４側）に位置している場合には、トリガー１２は自由である。 First, FIG. 16 shows a case where the lock is in the automatic locking mode. In this automatic locking mode, the engagement edge 61a of the mode switching interlocking member 61 for locking the trigger 12 is engaged with the engaged member provided on the trigger 12. It is not engaged with the joint (for example, protrusion) 12a. Since the mode switching interlocking member 61 of the first embodiment is provided to kill the movement of the trigger 12, the input means 31 is located on the left side (front 4 side) in the drawing. The trigger 12 is free.

しかしながら、入力手段３１が図面上、右側（フロント４側）から離れた場合には、すなわち、矢印で示すように、入力手段３１が押し込まれ場合には、モード切換え用連動部材６１は係合手段（入力手段３１のガイド溝６３、連動部材の係合ピン６４）６２を介してトリガー１２をロックする方向へと若干回転するので、錠前は連続解錠モードに成る。なお、この第１実施例では、入力手段３１の後端部に水平方向に段差状に設けた案内部分（ガイド溝）６３が設けられ、一方、モード切換え用連動部材６１の遊端部６１ｂには前記案内部分６３に常時係合する係合ピン６４が設けられている。したがって、入力手段３１を繰り返して押し込むと、モード切換え用連動部材６１は係合手段６２を介して固定軸６５を支点に時計方向又は反時計方向へと回転し、その係合縁部６１ａがトリガー１２の被係合部（突起）１２ａと係脱する。 However, when the input means 31 is away from the right side (front 4 side) in the drawing, that is, as indicated by the arrow, when the input means 31 is pushed in, the mode switching interlocking member 61 is engaged with the engaging means. Since the trigger 12 is slightly rotated in the direction of locking the trigger 12 via the guide groove 63 of the input means 31 and the engaging pin 64 of the interlocking member, the lock is in the continuous unlocking mode. In this first embodiment, a guide portion (guide groove) 63 provided in a step shape in the horizontal direction is provided at the rear end portion of the input means 31, while the free end portion 61 b of the mode switching interlocking member 61 is provided at the rear end portion of the input means 31. Is provided with an engaging pin 64 that is always engaged with the guide portion 63. Therefore, when the input means 31 is repeatedly pushed, the mode switching interlocking member 61 rotates clockwise or counterclockwise with the fixed shaft 65 as a fulcrum via the engagement means 62, and the engagement edge 61a is triggered. The 12 engaged portions (protrusions) 12a are engaged and disengaged.

ところで、本実施例では、縦長錠箱４の内部空間を有効的に活用するために、摺動部材１６は錠箱４の前壁内面と錠箱後壁の各内面の間を、傾斜案内部を介して傾方向に往復運動をする。また、動力源（付勢手段）２３は、安定した状態で作用するように、捩じりコイルバネ２３ａと、該捩じりコイルバネの螺旋状中央部を横柱で支持する可動のバネガイド２３ｂとから成る。 By the way, in this embodiment, in order to effectively use the internal space of the vertically long lock box 4, the sliding member 16 is provided between the inner surface of the front wall of the lock box 4 and the inner surface of the rear wall of the lock box. Reciprocates in the tilt direction via The power source (biasing means) 23 includes a torsion coil spring 23a and a movable spring guide 23b that supports the spiral central portion of the torsion coil spring with a horizontal column so that the power source (biasing means) operates in a stable state. Become.

さらに、ダルマ２１には、駆動リンク１４のみならず、作動アーム２５の上端部が枢支され、一方、該作動アームの下端部には、錠箱側に設けられた案内切欠部２７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２６を取付け、該デッド用ストッパは、前記デッド１４が付勢手段２３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２７に案内されてデッド１４の後端面をロックする。 Furthermore, not only the drive link 14 but also the upper end of the operating arm 25 is pivoted on the dharma 21, while the lower end of the operating arm is directly or directly connected to a guide notch 27 provided on the lock box side. An indirectly guided recumbent dead stopper 26 is attached, and the dead stopper is guided by the guide notch 27 when the dead 14 is fully projected by the urging force of the urging means 23. To lock the rear end face of the dead 14.

この欄では、図１８乃至図２６に示す本発明の第２実施例と、図２７のトリガーを初期位置へ復帰させる別の実施例をそれぞれ説明する。なお、これらの実施例を説明するに当って、前記第１実施例と同一の部分には同一又は同様の符号を付して重複する説明を省略する。 In this section, a second embodiment of the present invention shown in FIGS. 18 to 26 and another embodiment for returning the trigger of FIG. 27 to the initial position will be described. In the description of these embodiments, the same parts as those in the first embodiment are denoted by the same or similar reference numerals, and redundant description is omitted.

本発明の第２実施例と前記第１実施例と主に異なる点は、モード切換え用連動部材６１は、「トリガー１２をロックするか否か」、という観点から入力手段３１に連動するように組み合わせられているのに対して、第２実施例のモード切換え用連動部材６１Ａは、閉扉時にトリガー１２Ａが後退しても、「該トリガー１２Ａからの力が解錠状態保持機構１５の摺動部材用ストッパレバー１７に伝わらないようにすること」、という観点から入力手段３１に連動するように組み合わせられている。 The main difference between the second embodiment of the present invention and the first embodiment is that the mode switching interlocking member 61 is interlocked with the input means 31 from the viewpoint of “whether or not the trigger 12 is locked”. In contrast, the mode switching interlocking member 61A according to the second embodiment is configured so that “the force from the trigger 12A is a sliding member of the unlocked state holding mechanism 15 even if the trigger 12A is retracted when the door is closed. From the viewpoint of “not to be transmitted to the stopper lever 17”.

そこで、細部的事項の説明は割愛するが、この第２実施例のモード切換え用連動部材６１Ａは、トリガー１２Ａと摺動部材用ストッパレバー１７との間に介在する「間接部材」に相当するもので、例えばニ物品の共働片と、該共働片を初期位置へ戻す復帰手段とから構成されている。 Therefore, although detailed description is omitted, the mode switching interlocking member 61A of the second embodiment corresponds to an “indirect member” interposed between the trigger 12A and the stopper lever 17 for the sliding member. Thus, for example, it is composed of a cooperating piece of the article and return means for returning the cooperating piece to the initial position.

この第２実施例は、自動施錠モードの場合には、トリガー１２Ａが後退動した時に、ストッパレバー１７はトリガーと共働するモード切換え用連動部材（間接部材）６１Ａを介して回転する。間接部材６１Ａは、トリガー１２Ａの後端部とストッパレバー１７の第１係合腕１７ａの間に互いに共働或いは連係することができるように介在している。 In the second embodiment, in the automatic locking mode, when the trigger 12A moves backward, the stopper lever 17 rotates via a mode switching interlocking member (indirect member) 61A that cooperates with the trigger. The indirect member 61A is interposed between the rear end portion of the trigger 12A and the first engagement arm 17a of the stopper lever 17 so as to be able to cooperate or link with each other.

しかして、間接部材６１Ａは、例えば右手の三本の指をそれぞれ所定角度広げた格好の押圧片６６と、この押圧片６６に係合すると共にストッパレバー１７の第１係合腕１７ａと係合する可動片６７とから成る。 Thus, the indirect member 61A is engaged with, for example, a suitable pressing piece 66 in which three fingers of the right hand are expanded by a predetermined angle, and the first engaging arm 17a of the stopper lever 17 while engaging with the pressing piece 66. And a movable piece 67.

もちろん、設計如何によっては、間接部材６１Ａを複数片の組み合わせではなく、「一
つの部材」にすることができる。しかしながら、望ましくは、ストッパレバー１７を確実に回転させるため、或いは戸枠の縦枠と開閉体３の縦框３ａとの間のクリアランス等を考慮して、前記押圧片６６は、例えばトリガー１２Ａが第１バネ部材６８のバネ部材のバネ力に抗して後退する際に、若干後退動しながら該トリガー１２Ａの後端部の係合部１２ｄから離れる後退・回転型に構成し、また、前記可動片６７は、前記押圧片６６の後方アームに押圧されながら後方へと位置変位する後退型に構成する。 Of course, depending on the design, the indirect member 61 </ b> A can be “one member” instead of a combination of a plurality of pieces. However, desirably, the pressing piece 66 is, for example, the trigger 12A in order to rotate the stopper lever 17 surely or considering the clearance between the vertical frame of the door frame and the vertical rod 3a of the opening / closing body 3. When the first spring member 68 is retracted against the spring force of the spring member, the first spring member 68 is configured to be retracted and rotated away from the engaging portion 12d at the rear end of the trigger 12A while moving slightly backward. The movable piece 67 is configured as a retractable type that is displaced rearward while being pressed by the rear arm of the pressing piece 66.

ところで、押圧片６６は、中央部分６６ａから先端部へと延在しかつトリガー１２Ａの係合部１２ｄに係脱する前方アーム６６ｂと、前記中央部分６６ａから後方へと略水平状態に延在すると共に、錠箱４の一側壁の内壁面にガイド６９を介して案内されるように後方へと略水平状態に延在する後方アーム６６ｃと、前記中央部分６６ａから上方に延在しかつ錠箱内に適宜に配設された第２バネ部材７１のバネ力に抗して回転変位する上方アーム６６ｄをそれぞれ有している。 By the way, the pressing piece 66 extends from the central portion 66a to the tip portion, and extends in a substantially horizontal state from the front portion 66b engaged with and disengaged from the engaging portion 12d of the trigger 12A and from the central portion 66a to the rear. A rear arm 66c extending in a substantially horizontal state so as to be guided to the inner wall surface of one side wall of the lock box 4 via a guide 69, and extending upward from the central portion 66a and the lock box Each upper arm 66d is rotationally displaced against the spring force of the second spring member 71 appropriately disposed therein.

一方、引き上げ用連動部材３２Ａは、第１実施例の信号取得用連動部材３２に相当する
部材であり、その具体的構成は、信号取得用連動部材３２と同様である。したがって、その形態は特に問わないが、例えば先端部に錠箱側の横軸４４に外嵌合する筒状嵌合部４５を有すると共に、該筒状嵌合部４５に腕状の引き上げ用兼用被案内部４６が連設している（便宜上、信号取得用連動部材３２と同様の符号を用いる）。
付言すると、引き上げ用連動部材３２Ａは、その先端部に筒状嵌合部４５と、該筒状嵌合
部からＬ字形状に連設する係合端部４６とを有し、前記係合端部４６の一側壁には、入力手段３１に設けたピン状の係合部４０が係合する、水平方向に段差状の被案内部分４６ｂが形成されている。 On the other hand, the pulling interlocking member 32A is a member corresponding to the signal acquiring interlocking member 32 of the first embodiment, and its specific configuration is the same as that of the signal acquiring interlocking member 32. Accordingly, the form thereof is not particularly limited. For example, the front end portion has a cylindrical fitting portion 45 that is externally fitted to the horizontal shaft 44 on the lock box side, and the cylindrical fitting portion 45 is also used for arm-like lifting. A guided portion 46 is provided continuously (for the sake of convenience, the same reference numerals as those of the signal acquisition interlocking member 32 are used).
In other words, the pulling-up interlocking member 32A has a cylindrical fitting portion 45 at its distal end, and an engagement end portion 46 that is provided in an L-shape from the cylindrical fitting portion. On one side wall of the portion 46, a stepped guided portion 46 b is formed in the horizontal direction to which the pin-shaped engaging portion 40 provided in the input means 31 is engaged.

そして、前記腕状の引き上げ用兼用被案内部４６は、つまり、押圧片６６引き上げ用係合部分４６は、押圧片６６の中央部の係合部分に係合している。このように、第２実施例のモード切換え用連動部材（間接部材）６１Ａは、第１実施例の信号取得用連動部材３２を共働片の一つとして代用している。 The arm-like lifted guided portion 46, that is, the pressing piece 66 raising engagement portion 46 is engaged with the engagement portion at the center of the pressing piece 66. Thus, the mode switching interlocking member (indirect member) 61A of the second embodiment substitutes the signal acquisition interlocking member 32 of the first embodiment as one of the cooperating pieces.

さて、図１８は自動動施錠モードの状態を示す。図１９は自動施錠モードの状態における開扉時の状態である。自動施錠モードでは、入力手段がフロント板側に位置しているので、押圧片６６は引き上げ用連動部材３２Ａによって上方に引き上げられていない。した
がって、図２０で示すように、閉扉時、トリガー１２Ａがやや回転しながら後退動すると（錠箱側の傾斜状ガイド部分は省略）、前述したように、ストッパレバー１７は、間接部材６１Ａを介してトリガー１２Ａの影響を受け、摺動部材１６に対してストッパを解く方向へと回転する。それ故に、デッド１４は動力源２３のバネ力により錠箱から突出する。これに対して、図２１は連続解錠モードの状態を示す説明図である。この場合、入力手段３１はフロント４の開口９を介して指で押し込まれ、フロント板側から多少離れている。入力手段３１を押し込むと、モード切換え用連動部材（間接部材）６１Ａの可動片６７は固定ピン４０を支点にして、紙面上、反時計方向へと回転するので、その引き上げ用係合部分４６は、上方方向へと位置変位する。 FIG. 18 shows a state of the automatic movement locking mode. FIG. 19 shows a state when the door is opened in the automatic locking mode. In the automatic locking mode, since the input means is located on the front plate side, the pressing piece 66 is not lifted upward by the pulling interlocking member 32A. Therefore, as shown in FIG. 20, when the trigger 12A moves backward while rotating slightly when the door is closed (the inclined guide portion on the lock box side is omitted), as described above, the stopper lever 17 is interposed via the indirect member 61A. Under the influence of the trigger 12A, the sliding member 16 rotates in the direction of releasing the stopper. Therefore, the dead 14 protrudes from the lock box by the spring force of the power source 23. On the other hand, FIG. 21 is an explanatory view showing a state of the continuous unlocking mode. In this case, the input means 31 is pushed by a finger through the opening 9 of the front 4 and is somewhat separated from the front plate side. When the input means 31 is pushed in, the movable piece 67 of the mode switching interlocking member (indirect member) 61A rotates counterclockwise on the paper surface with the fixed pin 40 as a fulcrum. The position is displaced upward.

したがって、押圧片６６は後方アーム６６ｃの端部を支点にして、かつその中央部の係合部分を介して上方へと持ち上げられ、これにより、錠前は連続解錠モードの状態となる。図２２は開扉時から閉扉時になる時、解錠状態保持機構１５が後退動するトリガーの影響を受けないことを示す（連続解除モード）。 Accordingly, the pressing piece 66 is lifted upward with the end portion of the rear arm 66c as a fulcrum and through the engaging portion at the center thereof, whereby the lock is in the continuous unlocking mode. FIG. 22 shows that the unlocked state holding mechanism 15 is not affected by the reverse movement trigger when the door is closed from the time of opening (continuous release mode).

次に、図２７は、トリガー１２Ａを初期位置へ復帰させる別の実施例を示す説明図である。トリガー１２Ａは、先端部にマグネットを有し、閉戸時には戸枠側のマグネットの極性或いは金属片８１に対応して後退動し、一方、開扉時には、フロント板４の開口縁部に取付けられたストッパ機能を有するフロントマグネット極性或いは金属片８１に対応して初期位置へと前進する。 Next, FIG. 27 is an explanatory view showing another embodiment for returning the trigger 12A to the initial position. The trigger 12A has a magnet at the tip, and when the door is closed, the trigger 12A moves backward in accordance with the polarity of the magnet on the door frame side or the metal piece 81. On the other hand, when the door is opened, the trigger 12A is attached to the opening edge of the front plate 4. It moves forward to the initial position corresponding to the polarity of the front magnet having the stopper function or the metal piece 81.

なお、本実施例のトリガー（１２、１２Ａ）は、その形態如何を問わず、先端部にマグネットを有するが、戸枠１側に小突起を設けた場合には、閉戸時、トリガーの先端部は、前記小突起に押されて後退するので、前記マグネットは本質的要件ではない。しかしながら、望ましくは「マグネットトリガー」を採用している。また、詳細な説明を割愛するが、本実施例では、駆動モータの駆動力で回転可能な伝動歯車が存在し、該伝動歯車の一側面の縁部に摺動部材用ストッパレバーの係止状態を解くための突起が設けられている。 The trigger (12, 12A) of this embodiment has a magnet at the tip regardless of its form, but when a small protrusion is provided on the door frame 1 side, the tip of the trigger is closed when the door is closed. Since the part is pushed back by the small protrusion, the magnet is not an essential requirement. However, a “magnet trigger” is preferably used. Further, although detailed description is omitted, in this embodiment, there is a transmission gear that can be rotated by the driving force of the drive motor, and the sliding member stopper lever is locked to the edge of one side surface of the transmission gear. A protrusion is provided for solving the problem.
