Description

本発明は、トリガー機構を備えた錠前に関する。 The present invention relates to a lock provided with a trigger mechanism.

特許文献１には、錠前の一例として電気錠が記載されている。この種の電気錠は、普通一般に、電気的に開閉が可能であると同時に、合鍵、サムターン摘み等の操作部材による操作力によっても機械的に開閉可能な施・解錠機構を備えている。 Patent Document 1 describes an electric lock as an example of a lock. In general, this type of electric lock is generally provided with a locking / unlocking mechanism that can be electrically opened and closed, and at the same time mechanically opened and closed by an operating force of an operating member such as a key lock or thumb turn knob.

ところで、従来、例えば錠前としての電気錠は、電気錠の施・解錠機構（デッドボルトの出没を制御する機構）に関しては、制御部の制御（電気回路や記憶部の情報）に頼るというのが一般的発想なので、駆動源としては、電動モータと機械的に開閉可能なシリンダ錠の両方のみで十分である、と考えられている。しかし、デッドボルトが電動モータ（駆動モータ）の駆動力により、例えば解錠状態から施錠状態へと移動している途中に於いて、該デッドボルトに錠箱側から側圧が掛かった場合には、該デッドボルトが錠箱から完全突出しない事態が生じ、現在、このような問題点を解消することが要望されている。 By the way, conventionally, for example, an electric lock as a lock depends on the control of the control unit (information on the electric circuit and the storage unit) regarding the locking / unlocking mechanism of the electric lock (mechanism for controlling the dead bolts). Therefore, it is considered that only an electric motor and a mechanically openable / closable cylinder lock are sufficient as a drive source. However, when the dead bolt is moved from the unlocked state to the locked state by the driving force of the electric motor (drive motor), for example, when a side pressure is applied to the dead bolt from the lock box side, A situation has arisen in which the deadbolt does not completely protrude from the lock box, and it is currently desired to solve such problems.

また、施錠状態を電動又は手動で解錠状態にしたまま開閉体を開いたときに、錠箱内に後退した施錠片の解錠状態を保持する解錠状態保持機構と、一方、開閉体を閉じた時、トリガーの作動により前記解錠状態保持機構の解錠状態が解かれ、これにより前記施錠片が錠箱から自動的に突出して自動施錠状態となる錠前のような新規な錠前を開発する場合、閉扉時、トリガーの後退動に起因して解錠状態保持機構の解錠状態が解かれると、該解錠状態保持機構を構成する摺動部材及びダルマが、電動モータ以外の駆動源以外の駆動源、例えば錠箱内の付勢手段の付勢力により作動して自動施錠状態になること期待される。なお、特許文献２には、
デッドボルトのラックと係合する係合歯を有する係止レバーと係脱するトリガー体を有するトリガー機構を備えた錠止装置（錠前）のの一例が開示されているものの、前記期待に答えることができない。 In addition, when the opening / closing body is opened while the locking state is electrically or manually unlocked, the unlocking state holding mechanism that holds the unlocking state of the locking piece retracted in the lock box, When unlocked, the unlocked state of the unlocked state holding mechanism is released by the operation of the trigger, and thus, a new lock such as a lock that automatically protrudes from the lock box and automatically locks is developed. When the unlocking state of the unlocked state holding mechanism is released due to the backward movement of the trigger when the door is closed, the sliding member and the dharma constituting the unlocked state holding mechanism are driven by a drive source other than the electric motor. It is expected to operate automatically by a biasing force of a driving source other than the above, for example, a biasing means in the lock box. In Patent Document 2,
An example of a locking device (lock) having a locking mechanism having a locking lever having an engaging tooth that engages with a rack of a dead bolt and a trigger body that engages and disengages is disclosed, but the above expectation is met. I can't.

また、前記プリント基板８１に接続されたリード線（信号線）８２のコネクタ８３は、扉、建物の壁面等の適宜箇所に設置された制御部（制御盤）８４に接続する制御部側リード線（信号線）８５のコネクタ８６に接続可能である。 Further, a connector 83 of a lead wire (signal wire) 82 connected to the printed circuit board 81 is connected to a control portion (control panel) 84 installed at an appropriate location such as a door or a wall surface of a building. It can be connected to a connector 86 of (signal line) 85.

また、図３及び図４で示すように、駆動モータ８０の出力軸には駆動歯車（傘歯車）８７や動力伝達歯車８８（減速機構）が配設されている。なお、特に図示しないが、自動施錠モード、又は連続解錠モードのいずれかに選択することができるモード切り換え手段（例えば操作スイッチ）が、例えば錠箱の前壁部、制御盤等の適宜箇所に設けられている。また、錠箱１内には、図示しないロック解除用回転体が適宜に配設されている。 As shown in FIGS. 3 and 4, a drive gear (bevel gear) 87 and a power transmission gear 88 (reduction mechanism) are disposed on the output shaft of the drive motor 80. Although not specifically shown, mode switching means (for example, an operation switch) that can be selected from either the automatic locking mode or the continuous unlocking mode is provided at an appropriate location such as the front wall of the lock box, the control panel, or the like. Is provided. In the lock box 1, an unlocking rotating body (not shown) is appropriately arranged.

さて、本実施例の主要部は、例えば図３、図５等で示すトリガー１１と、該トリガーに連動する解錠状態保持機構３１である。解錠状態保持機構３１は、例えば図５、図６等で示すように、錠箱１に軸支されたストッパレバー３３と、このストッパレバーの前記第２係合腕５３と係脱する被係合部３８を有すると共に、ダルマ３に噛合するラック４３を有する摺動部材３２と、前記ストッパレバー３３を前記摺動部材３２に係合する方向へ常時付勢するバネ部材５５とから構成されている。そして、第１実施例では、前記解錠状態保持機構３１のストッパレバー３３は、トリガー１１の後端部に直接係合し、また、後述の第１実施例では、前記ストッパレバー３３は、間接部材１２を介してトリガー１１の後端部に間接的に係合している。 Now, the main part of the present embodiment is a trigger 11 shown in FIGS. 3 and 5 and an unlocked state holding mechanism 31 interlocked with the trigger, for example. The unlocked state holding mechanism 31 includes, for example, a stopper lever 33 pivotally supported on the lock box 1 and a second engagement arm 53 of the stopper lever that is engaged with and disengaged as shown in FIGS. The sliding member 32 includes a coupling portion 38 and a rack 43 that meshes with the dharma 3, and a spring member 55 that constantly biases the stopper lever 33 in a direction to engage the sliding member 32. Yes. In the first embodiment, the stopper lever 33 of the unlocked state holding mechanism 31 is directly engaged with the rear end portion of the trigger 11, and in the first embodiment described later, the stopper lever 33 is indirectly connected. It is indirectly engaged with the rear end portion of the trigger 11 via the member 12.

図１はデッド４が錠箱１から突出した完全施錠位置、一方、図２はデッド４が完全施錠位置から完全解錠位置へと後退し、解錠状態保持機構３１のストッパレバー３３が摺動部材３２の横柱状の被係合部３８に対して係合した状態（解錠状態保持状態）である。 FIG. 1 shows the fully locked position in which the dead 4 protrudes from the lock box 1, while FIG. 2 shows that the dead 4 moves back from the fully locked position to the fully unlocked position, and the stopper lever 33 of the unlocked state holding mechanism 31 slides. It is a state engaged with the horizontal columnar engaged portion 38 of the member 32 (unlocked state holding state).

例えば電気錠Ｘの駆動モータ８０が解錠方向へ起動すると、歯車群と噛合するロック解除用回転体が回転し、摺動部材３２は錠箱側の直線案内長孔４８を介してスライドするので、摺動部材３２のラック板３５のラック４３と噛合するダルマ３は完全施錠位置から完全解錠位置まで回転する。したがって、デッド４は動力変換機構の一例である駆動リンク５を介して解錠位置へと戻される（図２）。また、電気錠Ｘは、図示しない合鍵操作によりダルマ３が解錠方向へ回転すると、完全施錠位置から完全解錠位置まで回転する。したがって、デッド４は動力変換機構５を介して解錠位置へと戻される（図２）。 For example, when the drive motor 80 of the electric lock X is activated in the unlocking direction, the unlocking rotating body meshing with the gear group rotates, and the sliding member 32 slides through the linear guide slot 48 on the lock box side. The dharma 3 that meshes with the rack 43 of the rack plate 35 of the sliding member 32 rotates from the fully locked position to the fully unlocked position. Therefore, the dead 4 is returned to the unlocked position via the drive link 5 which is an example of the power conversion mechanism (FIG. 2). Further, the electric lock X rotates from the fully locked position to the fully unlocked position when the dharma 3 is rotated in the unlocking direction by a keying operation (not shown). Therefore, the dead 4 is returned to the unlocking position via the power conversion mechanism 5 (FIG. 2).

このように、電動力であれ、手動の操作力であれ、図２で示すように解錠状態になると、バネ部材５５のバネ力により、解錠状態保持機構３１のストッパレバー３３は、解錠状態保持機構３１の摺動部材３２をロック（解錠状態を保持する状態）し、開閉体（例えば扉）２を開いても、デッド４の没入状態を保持する。 In this way, whether it is an electric force or a manual operation force, when the unlocked state is reached as shown in FIG. 2, the stopper lever 33 of the unlocked state holding mechanism 31 is unlocked by the spring force of the spring member 55. Even if the sliding member 32 of the state holding mechanism 31 is locked (a state in which the unlocked state is maintained) and the opening / closing body (for example, the door) 2 is opened, the immersion state of the dead 4 is maintained.

そこで、本実施例では、開閉体２を閉じると、図５で示すように、トリガー１１が錠箱１内へ後退動してストッパレバー３３が解錠状態の保持状態を解く方向へと回転し、ダルマ３は錠箱１内に配設された付勢手段７０の付勢力により自動的に施錠方向へと回動して、施錠片としてのデッド４が自動施錠状態になる。 Therefore, in this embodiment, when the opening / closing body 2 is closed, as shown in FIG. 5, the trigger 11 moves backward into the lock box 1 and the stopper lever 33 rotates in the direction to unlock the unlocked state. The dharma 3 is automatically rotated in the locking direction by the urging force of the urging means 70 disposed in the lock box 1, and the dead 4 as the locking piece is automatically locked.

（５）電気錠Ｘ等を詳細
電気錠Ｘ等を詳細に説明する。図２を参照にすると、Ｘは電気錠（錠前）、Ｙは戸枠、Ｚは受け金具である。また、１ａは錠箱１の前壁、１ｂは錠箱の後壁、１ｃは錠箱の幅広側壁（以下、「側壁」という。）、１ｄはデッドが出没する貫孔である。符号３は縦長錠箱１の下部側に図示しない受け座あるいは、座部を介して回動自在に設けられたダルマで、このダルマ３は、正面視側（図２、図１４）に全体の形状が見えるダルマ本体２１と、背面視側（図１５）に全体の形状が見える駆動カム２２とから成り、前記駆動カム２２は前記ダルマ本体２１と一体に結合している。 (5) Details of the electric lock X and the like The electric lock X and the like will be described in detail. Referring to FIG. 2, X is an electric lock (lock), Y is a door frame, and Z is a receiving metal fitting. Further, 1a is a front wall of the lock box 1, 1b is a rear wall of the lock box, 1c is a wide side wall (hereinafter referred to as "side wall") of the lock box, and 1d is a through hole in which a dead appears. Reference numeral 3 denotes a dharma provided on the lower side of the vertically long lock box 1 so as to be rotatable via a seat (not shown) or a seat, and this dharma 3 is arranged on the front view side (FIGS. 2 and 14). The dharma body 21 is visible and the drive cam 22 is visible as a whole when viewed from the rear (FIG. 15). The drive cam 22 is integrally coupled to the dharma body 21.

しかして、ダルマ本体２１は座部に嵌合する表環状部２１ａに、異形の不番開口が形成されている。周知のように、前記不番開口には、図示しないテールピースあるいは、連結杆が挿通され、該連結杆を介してシリンダ錠の内筒が連結されている。したがって、ダルマ３は操作部材としての合鍵の操作力によって回動可能である。 Thus, the Dalma main body 21 is formed with a deformed non-numbered opening in the front annular portion 21a fitted to the seat portion. As is well known, a tailpiece (not shown) or a connecting rod is inserted into the unnumbered opening, and an inner cylinder of a cylinder lock is connected through the connecting rod. Therefore, the dharma 3 can be rotated by the operation force of the combined key as the operation member.

また、ダルマ本体２１は、その表環状部２１ａに連設する円形状外周部２１ｂの一部にセクターギア２３と半径外方向へ山形状に突出する連結部２４をそれぞれ有している。前記セキターギア２３は、摺動部材３２のラック板３５に噛合し、一方、前記突起状連結部２４には、駆動リンク５が第２枢支ピン７を介して連結する。 Further, the dharma main body 21 has a sector gear 23 and a connecting portion 24 projecting in a mountain shape outward in the radial direction at a part of a circular outer peripheral portion 21b connected to the front annular portion 21a. The sexter gear 23 meshes with the rack plate 35 of the sliding member 32, while the drive link 5 is connected to the protruding connection portion 24 via the second pivot pin 7.

ダルマ本体２１の裏側に合体する駆動カム２２も、図１５で示すように側壁１ｃの座部に嵌合する裏環状部２２ａに異形の不番開口が形成されている。周知のように前記不番開口には図示しないサムターン軸が挿通され、該サムターン軸にサムターン摘みが連結されている。 As shown in FIG. 15, the drive cam 22 united with the back side of the dharma main body 21 is also formed with an irregularly shaped unnumbered opening in the back annular portion 22 a that fits into the seat portion of the side wall 1 c. As is well known, a thumb turn shaft (not shown) is inserted through the unnumbered opening, and a thumb turn knob is connected to the thumb turn shaft.

したがって、ダルマ３は、操作部材としてのサムターン摘みの操作力によっても回動可能である。また、駆動カム２２は、その裏環状部２２ａに連設する円形状外周部２２ｂの一部に半径外方向へ人さし指状に延伸する係合アーム２５と、該係合アーム２５の根元あるいは根元付近にバネ端用の小突起２６をそれぞれ有している。前記小突起２６には、例えば図１６及び図１７で示す付勢手段７０を構成する開脚変位バネ７１の他端部７１ｃが連結ピン２７を介して連結され、一方、前記係合アーム２５の折曲先端部は、後述の摺動部材３２を構成するラック板３５の被係合部に常時係合している。 Therefore, the dharma 3 can also be rotated by the operating force of the thumb turn knob as the operating member. Further, the drive cam 22 includes an engagement arm 25 that extends in a radial direction toward a part of a circular outer peripheral portion 22b that is connected to the back annular portion 22a, and a base of the engagement arm 25 or a vicinity of the base. Each has a small protrusion 26 for a spring end. For example, the other end 71c of an open leg displacement spring 71 constituting the biasing means 70 shown in FIGS. 16 and 17 is connected to the small protrusion 26 via a connecting pin 27. The bent tip portion is always engaged with an engaged portion of a rack plate 35 constituting a sliding member 32 described later.

次に、４はダルマ３の下方に水平状態に配設されたデッドで、該デッド４は短杆状の駆動リンク５を介して前記ダルマ３の突起部分に連結されている。付言すると、本実施例では、駆動リンク５は、その一端部がデッド側の第１枢支ピン６に、一方、他端部がダルマ側の第２枢支ピン７にそれぞれ軸支され、ダルマ３の回動力をデッド４の進退動（往復運動）に変換する。また本実施例では、デッド４を案内する案内手段（ガイド板、ガイド溝、ガイド突起等）については、特に図示しないが、デッド４は、デッド４及び側壁１ｃに設けられた案内手段に案内され、出没自在に戸枠Ｙの受け金具Ｚに係脱する。 Next, 4 is a dead disposed horizontally below the dharma 3, and the dead 4 is connected to the projecting portion of the dharma 3 via a short rod-shaped drive link 5. In addition, in this embodiment, one end of the drive link 5 is pivotally supported by the first pivot pin 6 on the dead side, and the other end is pivotally supported by the second pivot pin 7 on the Dharma side. The turning force of 3 is converted into advancing and retreating (reciprocating motion) of dead 4. In this embodiment, the guide means (guide plate, guide groove, guide protrusion, etc.) for guiding the dead 4 is not particularly shown, but the dead 4 is guided by the guide means provided on the dead 4 and the side wall 1c. Then, the door frame Y can be freely moved in and out of the bracket Z.

次に、３１はデッドの没入状態を保持する解錠状態保持機構で、該解錠状態保持機構３１は、摺動部材３２、該摺動部材用ストッパレバー３３及びバネ部材５５を含み、ダルマ３を基準として、望ましくは、ダルマ３よりも上方に配設されている。図６は解錠状態保持機構３１の摺動部材３２とストッパレバー３３をそれぞれ示す。 Next, 31 is an unlocked state holding mechanism for holding the dead immersion state. The unlocked state holding mechanism 31 includes a sliding member 32, a sliding member stopper lever 33, and a spring member 55. Is preferably arranged above the dharma 3. FIG. 6 shows the sliding member 32 and the stopper lever 33 of the unlocked state holding mechanism 31.

ここで、図７乃至図１３を参照にして、摺動部材３２の具体的構成を説明する。図８は、摺動部材３２の正面図であるが、該摺動部材３２は、図１２及び図１３で示すように垂直のスライダ板３４（図１２）と垂直のラック板３５（図１３）の二枚から構成され、これらのスライダ板３４とラック板３５は前後方向に接合している。 Here, with reference to FIG. 7 thru | or FIG. 13, the specific structure of the sliding member 32 is demonstrated. 8 is a front view of the sliding member 32. As shown in FIGS. 12 and 13, the sliding member 32 includes a vertical slider plate 34 (FIG. 12) and a vertical rack plate 35 (FIG. 13). The slider plate 34 and the rack plate 35 are joined in the front-rear direction.

図８を基準にすると、ラック板３５はスライダ板３４の手前側に位置し、両板３４，３５は水平方向に所定間隔離間して設けられた複数個の係合部、被係合部、水平切欠部３６，３７，３７ａ，３７ｂ，３７ｃと介して互いに共働するように組み合っている。 With reference to FIG. 8, the rack plate 35 is positioned on the front side of the slider plate 34, and both plates 34 and 35 are provided with a plurality of engaging portions, engaged portions, The horizontal notches 36, 37, 37a, 37b, and 37c are combined so as to cooperate with each other.

図８を参照にすると、３６はスライダ板３４の幅広下端部の手前側（前側）に突設された左右或いは上下の係合突起、これに対して、３７は前記係合突起３６に係合するようにラック板３５の下端部に形成された左右の水平案内切欠と水平案内長孔である。手前側のラック板３５は、これらの係合部３６，３７を介して、所定量水平方向へ往復可能である。 Referring to FIG. 8, reference numeral 36 denotes left and right or upper and lower engaging protrusions projecting on the front side (front side) of the wide lower end of the slider plate 34, while 37 is engaged with the engaging protrusion 36. The left and right horizontal guide notches and horizontal guide slots are formed at the lower end portion of the rack plate 35. The front rack plate 35 can reciprocate in a horizontal direction by a predetermined amount via these engaging portions 36 and 37.

また、３８，３９はスライダ板３４の中央部の前面に突設された左右の第１・第２案内突起部材で、図９の断面図と図１０の端面図と比較すると明らかなように、一方側（図９では左側）の第１案内突起部材（横柱状の被係合部）３８は、他方側（右側）の第２案内突起部材３９よりも手前側に多少突出している。 Reference numerals 38 and 39 denote left and right first and second guide projection members projecting from the front surface of the central portion of the slider plate 34. As is clear from comparison between the sectional view of FIG. 9 and the end view of FIG. The first guide protrusion member (horizontal columnar engaged portion) 38 on one side (left side in FIG. 9) slightly protrudes toward the front side from the second guide protrusion member 39 on the other side (right side).

しかして、前記左側の第１案内突起部材３８は、その基端部がスライダ板３４の傾斜状左端部に固定された状態でラック板３５の左端部の逃し用水平案内切欠３７ａを貫通する第１支軸３８ａと、この第１支軸３８ａに取付けられた第１スライダコロ３８ｂ、ストッパコロ３８ｃ等から成り、前記第１支軸３８ａの突出先端部は適宜にかしめられている（図９参照）。 Thus, the first guide protrusion member 38 on the left side passes through the escape horizontal guide notch 37a at the left end portion of the rack plate 35 with the base end portion fixed to the inclined left end portion of the slider plate 34. The first support shaft 38a is composed of a first slider roller 38b and a stopper roller 38c attached to the first support shaft 38a. The protruding tip of the first support shaft 38a is appropriately caulked (see FIG. 9).

付言すると、第１支軸３８ａの突出先端部は、望ましくは不番のワッシャと面一になるようにかしめられている。この第１案内突起部材３８は、本実施例では、後述するように「ロック部材」の機能も兼用している。 In addition, the protruding tip of the first support shaft 38a is preferably crimped so as to be flush with an unnumbered washer. In the present embodiment, the first guide projection member 38 also functions as a “lock member” as will be described later.

一方、前記右側の第２案内突起部材３９は、その基端部がスライダ板３４の突起状右端部に固定された状態で、ラック板３５の復帰バネ４０収納用水平切欠部３７ｂを貫通する第２支軸３９ａと、この第２支軸３９ａに取り付けられた第２スライダコロ３９ｂ等から成り、前記第２支軸３９ａの突起先端部も第１支軸３８ａのそれと同様に適宜にかしめられている。したがって、第２案内突起部材３９は、ストッパコロ３８ｃを有しない分、その長さは第１案内突起部材３８よりも短くなっている（図１０参照）。 On the other hand, the second guide projection member 39 on the right side has a base end portion fixed to the projecting right end portion of the slider plate 34, and the second guide projection member 39 passes through the return spring 40 housing horizontal cutout portion 37b of the rack plate 35. It consists of two support shafts 39a and a second slider roller 39b attached to the second support shaft 39a, and the tip end of the projection of the second support shaft 39a is caulked appropriately as well as that of the first support shaft 38a. . Therefore, the length of the second guide protrusion member 39 is shorter than that of the first guide protrusion member 38 because the stopper roller 38c is not provided (see FIG. 10).

また、スライダ板３５の第１・第２案内突起部材３８，３９の間には水平方向に所定長の復帰バネ４０用水平切欠部３７ｃが形成されている、それ故に、スライダ板３４の水平切欠部３７ｃの右端縁部には第１バネ受け部４１が設けられ、一方、ラック板３５の水平切欠部３７ｂの左端縁部には第２バネ受け部４２が設けられ、これらの第１・２バネ受け部４１，４２に復帰バネ４０の両端が支持された状態で両水平切欠部３７ｂ，３７ｃに収納される。 Further, a horizontal cutout portion 37c for a return spring 40 having a predetermined length is formed in the horizontal direction between the first and second guide projection members 38, 39 of the slider plate 35. Therefore, the horizontal cutout of the slider plate 34 is provided. A first spring receiving portion 41 is provided at the right end edge of the portion 37c, while a second spring receiving portion 42 is provided at the left end edge of the horizontal cutout portion 37b of the rack plate 35. The both ends of the return spring 40 are supported by the spring receiving portions 41 and 42 and are housed in both horizontal cutout portions 37b and 37c.

さらに、ラック板３５の構成について付言すると、ラック板３５の下端縁部には水平方向にダルマ３のセクターギア２３を噛合するラック４３が形成されており、また、ラック板３５の上端縁部の適宜個所には、後述するストッパレバー３３を押圧して解錠状態保持機構３１のロック状態（ストッパレバーがスライダ３４の第１案内突起部材３８に係合している係止状態）を解くための傾斜状押圧部４４が形成されており、さらに、ラック板３５の裏側の一端部には、ダルマ３の駆動カム２２の係合アーム２５の内側が面接触状態で係合する突起状の被係合部４５が設けられている。 Further, with regard to the configuration of the rack plate 35, a rack 43 that meshes the sector gear 23 of the dharma 3 in the horizontal direction is formed at the lower end edge of the rack plate 35. At an appropriate place, a stopper lever 33, which will be described later, is pressed to unlock the unlocked state holding mechanism 31 (the locked state where the stopper lever is engaged with the first guide projection member 38 of the slider 34). An inclined pressing portion 44 is formed, and at one end on the back side of the rack plate 35, a protrusion-like engagement with which the inner side of the engagement arm 25 of the driving cam 22 of the dharma 3 is engaged in a surface contact state. A joint portion 45 is provided.

したがって、本実施例では、摺動部材３２は、ストッパレバー３３の先端部と係脱するロック部材３８を有するスライダ板３４と、このスライダ板に係合部・被係合部３６，３７を介して共働するように組み合わせられ、かつダルマ３のセクターギア２３と噛合するラック４３を有するラック板３５と、このラック板のバネ受け部４２と前記スライダ板のバネ受け部４１との間に組み込まれたラック板用復帰バネと４０から成り、例えば合鍵、サムターン摘み等の操作部材を若干施錠方向へ回転操作すると、摺動部材３２のラック板３５は、ラック板用復帰バネ４０のバネ力に抗して若干施錠方向へと移動すると共に、ストッパレバー３３を押圧して解錠状態保持機構３１のロック状態を解くこともできる。 Therefore, in the present embodiment, the sliding member 32 includes the slider plate 34 having the lock member 38 that engages and disengages with the tip end portion of the stopper lever 33, and the slider plate via the engaging portions / engaged portions 36 and 37. And a rack plate 35 having a rack 43 that meshes with the sector gear 23 of the dharma 3 and is incorporated between the spring receiving portion 42 of the rack plate and the spring receiving portion 41 of the slider plate. The rack plate 35 of the sliding member 32 is subjected to the spring force of the rack plate return spring 40 when the operation member such as a key lock or thumb turn knob is slightly rotated in the locking direction. It is possible to move slightly in the locking direction against this, and press the stopper lever 33 to unlock the unlocked state holding mechanism 31.

ここで、図１１を参照にして、摺動部材３２を直線方向に案内するガイド板４７について説明する。ガイド板４７は、後述するストッパレバー３３と共に、錠箱の一側壁１ｃ（図２を基準にすると、手前側の正面の側壁）の内壁面に沿って適宜の固定されている。このガイド板４７の数、厚さ、形状等は任意に設計することができる事項であるが、単数又は複数のガイド板４７は、水平又は斜め方向（本実施例）の直線案内長孔４８を有し、該直線案内長孔４８には、第１・第２案内突起部材３８，３９の各スライダコロ３８ｂ、３９ｂが摺動自在に嵌合している。 Here, the guide plate 47 for guiding the sliding member 32 in the linear direction will be described with reference to FIG.

As shown in FIG. 2, the biasing means 70 is disposed in a space between the drive cam 22 of the dharma 3 and the front wall 1a of the lock box. The biasing means 70 of this embodiment includes a torsion coil spring 71 and a spring guide 72 that guides the torsion coil spring in a predetermined direction while supporting the torsion coil spring.

しかして、前記捩じりコイルバネ７１は、その両端部を延伸させた開脚変位バネであり、該開脚変位バネは７１、その螺旋状中央部７１ｂを保持しかつ一端部７１ａが固定軸７４を介して軸支された可動の前記バネガイド７２を介して開脚変位する。 Thus, the torsion coil spring 71 is an open leg displacement spring having both ends extended, and the open leg displacement spring 71 holds the spiral central portion 71b and the one end portion 71a is a fixed shaft 74. The leg is displaced through the movable spring guide 72 that is pivotally supported via the shaft.

前述したように、開脚変位バネ７１の他端部７１ｃは、本実施例では、ダルマ３の駆動カム２２の小突起２６に連結ピン２７を介して取付けられている。そして、本実施例の捩じりコイルバネ７１は、デッド４に対して、いわゆる側圧が掛かっている（負荷されている）場合であっても、電動モータの起動、操作部材による操作起動等による初期動力によって、摺動部材３２に対する解錠状態保持機構３１のロック状態が解かれている限り、以後、ダルマ３を介してデッド４を完全に押し出すことができるよう、そのバネ力が設定されている。 As described above, the other end 71c of the open leg displacement spring 71 is attached to the small protrusion 26 of the drive cam 22 of the dharma 3 via the connecting pin 27 in this embodiment. In addition, the torsion coil spring 71 of the present embodiment is an initial stage due to the activation of the electric motor, the operation activation by the operation member, etc., even when a so-called lateral pressure is applied (loaded) to the dead 4. As long as the unlocked state holding mechanism 31 is unlocked with respect to the sliding member 32 by power, the spring force is set so that the dead 4 can be completely pushed out through the dharma 3 thereafter. .

図１７は、バネガイド７２の一例を示す。バネガイド７２は、錠箱１の側壁１ｃを摺接する垂直ベース板部７２ａと、この垂直ベース板部７２ａの左右端部に連設する枠状の囲い部７２ｂとを有し、前記垂直ベース板部７２ａの基端部には軸孔が形成され、一方、垂直ベース板部７２ａのやや幅広自由端部の内面には前述した螺旋状中央部７１ｂが外嵌合する横柱７２ｃが設けられている。バネガイド７２は、前記横柱７２ｃを有しているので、開脚変位バネの螺旋状中央部７１ｂの巻数を多くしても、容易に変形せず、形態が常に一定の状態に保持されている。このように、本実施例の付勢手段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を横柱７２ｃで支持する可動のバネガイド７２とから成ることを特徴とする。 FIG. 17 shows an example of the spring guide 72. The spring guide 72 has a vertical base plate portion 72a that is in sliding contact with the side wall 1c of the lock box 1, and a frame-shaped enclosure portion 72b that is continuous with the left and right ends of the vertical base plate portion 72a. A shaft hole is formed in the base end portion of 72a, and on the other hand, a horizontal column 72c to which the above-described spiral central portion 71b is fitted is provided on the inner surface of the slightly wide free end portion of the vertical base plate portion 72a. . Since the spring guide 72 has the horizontal column 72c, even if the number of turns of the spiral central portion 71b of the open leg displacement spring is increased, the spring guide 72 is not easily deformed and the form is always kept constant. . As described above, the urging means 70 of the present embodiment includes the torsion coil spring 71 and the movable spring guide 72 that supports the spiral central portion of the torsion coil spring with the horizontal column 72c. .

次に、例えば図１９、図２１、図２２等を参照にして、ダルマ３の回動運動をデッド４の直線運動に変換する機構及びデッド用のストッパ１９について説明する。本実施例の動力変換手段５は、例えば駆動リンク５である。この駆動リンク５は、その一端部がデッド４側の第１枢支ピン６に、一方、他端部がダルマ側の第２枢支ピン７にそれぞれ軸支され、操作部材の操作力又は図示しない駆動モータの駆動力で回転するダルマ３の回転力を、デッド４の進退動に変換する。 Next, a mechanism for converting the rotational movement of the dharma 3 into a linear movement of the dead 4 and the dead stopper 19 will be described with reference to FIGS. The power conversion means 5 of the present embodiment is, for example, a drive link 5. One end of the drive link 5 is pivotally supported on the first pivot pin 6 on the dead 4 side, and the other end is pivotally supported on the second pivot pin 7 on the dharma side. The rotational force of the dharma 3 that is rotated by the drive force of the drive motor that is not converted is converted into the forward and backward movement of the dead 4.

しかして、本実施例では、駆動リンク５は、その一端部（先端部）がデッド４の本体４ａの上辺に設けられた突起４ｂに第１枢支ピン６を介して軸支され、一方、その他端部（末端部）は、ダルマ３の外周縁部に第２枢支ピン７を介して直接軸支されている。符号１９はデッド用ストッパで、該デッド用ストッパ１９は、施錠時、駆動リンク５とは異なる作動アーム１８の位置変位により、デッド４の後端面と錠箱１の後壁１ｂの内壁面との間の空間に入り込んで該デッド４の後退を阻止する。 Thus, in the present embodiment, the drive link 5 is pivotally supported by the protrusion 4b provided on the upper side of the main body 4a of the dead 4 via the first pivot pin 6, while the drive link 5 has one end (tip). The other end portion (terminal portion) is directly pivotally supported on the outer peripheral edge portion of the dharma 3 via the second pivot pin 7. Reference numeral 19 denotes a dead stopper, and the dead stopper 19 is located between the rear end surface of the dead 4 and the inner wall surface of the rear wall 1b of the lock box 1 by the displacement of the operating arm 18 different from the drive link 5 at the time of locking. The space between them is entered to prevent the dead 4 from moving backward.

ところで、前記作動アーム１８は、前記駆動リンク５に対して二本目のリンク（駆動リンクに連結されていないこと）である。付言すると、本実施例では、１本目、二本目及び三本目をそれぞれ連係させて一つのリンク機構を構成していない。また、その一端部（上端部）がダルマ３の周端部にダルマ側の第２枢支ピン７に対して所定間隔離間するダルマ側の第３枢支ピン８に軸支され、かつ、他端部（下端部）にデッド用ストッパ１９を一体的に有し、該デッド用ストッパ１９は、錠箱の左右の側壁１ｃ、１ｃに直接又は間接的（本実施例）に設けられた上下方向の曲線形状案内切欠部２０、２０に案内されると共に、施錠時、前記案内切欠部２０の終端部分に相当する垂直部２０ｃに落ち込んで、該デッド４の後退を確実に阻止（ロック）する横棒突起である。 Meanwhile, the operating arm 18 is a second link (not connected to the drive link) with respect to the drive link 5. In addition, in this embodiment, one link mechanism is not configured by linking the first, second, and third links. Further, one end portion (upper end portion) thereof is pivotally supported by the third pivot pin 8 on the dharma side which is spaced apart from the second pivot pin 7 on the dharma side by a predetermined distance at the peripheral end portion of the dharma 3, and others An end (lower end) is integrally provided with a dead stopper 19, which is provided in the vertical direction provided directly or indirectly (in this embodiment) on the left and right side walls 1c, 1c of the lock box. The curved shape guide cutout portions 20 and 20 are guided to the vertical portion 20c corresponding to the end portion of the guide cutout portion 20 during locking, and the dead 4 is prevented from retreating (locking). It is a rod projection.

また、前記曲線形状案内切欠部２０は、錠箱１の左右側壁１ｃ、１ｃの各内壁面にそれぞれ固定された一対の案内固定板９，９にそれぞれ対向するように形成されている。そして、曲線形状案内切欠部２０は、上下方向に「ややＳ字型カーブ」を描くように形成され、その上端部に相当する垂直部分の始点２０ａから、中途部に相当する弧状或いは傾斜状部分２０ｂと、終端部分に相当する垂直部２０ｃとから成る。また、横棒突起のデッド用ストッパ１９は、その両端部が前記左右一対の曲線形状案内切欠部２０、２０に架設された状態で係合している。 The curved guide cutout portion 20 is formed so as to face a pair of guide fixing plates 9 and 9 fixed to the inner wall surfaces of the left and right side walls 1c and 1c of the lock box 1, respectively. The curved guide cutout portion 20 is formed so as to draw a “slightly S-shaped curve” in the vertical direction, and from the start point 20a of the vertical portion corresponding to the upper end portion thereof, the arc-shaped or inclined portion corresponding to the middle portion 20b and a vertical portion 20c corresponding to the end portion. Further, the dead stopper 19 for the horizontal bar protrusion is engaged in a state where both ends thereof are installed on the pair of left and right curved guide notches 20 and 20.

図２１及び図２３は、解錠時から施錠時に至る駆動リンク５とデッド用ストッパ１９の動きを示す各概略説明図である。解錠時、デッド４は、錠箱１内に後退している。この時、駆動リンク５は水平状態であるのに対して、作動アーム１８はデッド４の上辺に垂直状態になっている。 FIGS. 21 and 23 are schematic explanatory views showing the movement of the drive link 5 and the dead stopper 19 from unlocking to locking. At the time of unlocking, the dead 4 is retracted into the lock box 1. At this time, the drive link 5 is in a horizontal state, whereas the operating arm 18 is in a state perpendicular to the upper side of the dead 4.

付言すると、駆動リンク５の第１枢支ピン６と第２枢支ピン７は、同一水平線上に位置し、また、作動アーム１８の第３枢支ピン８の真下に横棒状のストッパ１９が位置している。そして、作動アーム１８の下端部又はストッパ１９は、デッド４の後端部に形成された傾斜状受け面１０の上端部分１０ａに当接している。 In addition, the first pivot pin 6 and the second pivot pin 7 of the drive link 5 are located on the same horizontal line, and a horizontal bar-shaped stopper 19 is located directly below the third pivot pin 8 of the operating arm 18. positioned. The lower end portion of the operating arm 18 or the stopper 19 is in contact with the upper end portion 10 a of the inclined receiving surface 10 formed at the rear end portion of the dead 4.

（６）主要部の作用
開扉時、例えば図３で示すようにデッド４が錠箱１内に没入し、かつ、この没入状態が解錠状態保持機構３１によって保持されている時、前記開閉体２を閉じると、前記トリガー１１は戸枠側の図示しないマグネットの極性に対応して反発し、図５で示す矢印Ａ方向へと後退動する。そうすると、解錠状態保持機構３１のストッパレバー３３は、バネ部材５５のバネ力に抗して、かつ固定支軸５１を支点にして、矢印Ｂの時計方向へと若干回転する。つまり、ストッパレバー３３は、トリガー１１の作動によって、解錠状態保持機構３１の解錠状態の保持状態を解く方向へと回転する。そうすると、ダルマ３は錠箱内の付勢手段７０の付勢力により自動的に施錠方向へと回動して、施錠片４が自動施錠状態になる。 (6) Action of main part When the door is opened, for example, as shown in FIG. 3, when the dead 4 is immersed in the lock box 1 and this immersed state is held by the unlocked state holding mechanism 31, the opening and closing When the body 2 is closed, the trigger 11 repels in accordance with the polarity of a magnet (not shown) on the door frame side and moves backward in the direction of arrow A shown in FIG. Then, the stopper lever 33 of the unlocked state holding mechanism 31 slightly rotates in the clockwise direction of the arrow B against the spring force of the spring member 55 and with the fixed support shaft 51 as a fulcrum. That is, the stopper lever 33 rotates in the direction to unlock the unlocked state holding mechanism 31 by the operation of the trigger 11. Then, the dharma 3 is automatically rotated in the locking direction by the urging force of the urging means 70 in the lock box, and the locking piece 4 is in the automatic locking state.

図１９を参照にして付言すると、トリガー１１が後退動すると、解錠状態保持機構３１の摺動部材３２に対するストッパレバー３３の係止が解かれるので、直ちに動力源としての付勢手段７０のバネ力がダルマ３に作用する。そうすると、ダルマ３は反時計方向に回転し始める。ダルマ３が反時計方向に回転すると、ダルマ３とデッドボルト４は、第１枢支ピン６、第２枢支ピン７及び駆動リンク５を介して連結されているから、前記駆動リンク５がダルマ３の回転力を変換する押圧機能（突っ張り機能）を発揮し、デッド４は突出方向へと水平移動する。 Referring to FIG. 19, when the trigger 11 moves backward, the stopper lever 33 is unlocked from the sliding member 32 of the unlocked state holding mechanism 31, so that the spring of the biasing means 70 as a power source is immediately released. Force acts on Dharma 3. Then, the dharma 3 starts to rotate counterclockwise. When the dharma 3 rotates counterclockwise, the dharma 3 and the dead bolt 4 are connected via the first pivot pin 6, the second pivot pin 7 and the drive link 5. 3 exerts a pressing function (stretching function) for converting the rotational force of 3, and the dead 4 moves horizontally in the protruding direction.

そして、ダルマ３が引き続き回転し続けると、解錠状態から施錠状態に至る途中に於いて、デッド用ストッパ１９が曲線形状案内切欠部２０の中途部分２０ｂに案内されながらデッド４の後端部の傾斜状受け面１０を押し付ける。つまり、二本目のリンクに相当する作動アーム１８が、駆動リンク５に共働として補助的にデッドボルト４を押し付ける。
施錠時、駆動リンク５が所定位置にて傾倒状態になると、ストッパ１９が案内切欠部の終点に相当する垂直部２０ｃに落ち込んで、該デッド４の後退を阻止する。付言すると、デッド用ストッパ１９は、少なくとも錠箱１の左右の側壁に間接的に設けられた一対の曲線形状案内切欠部２０、２０の垂直部分２０ｃ、２０ｃに係止状態に架設されているので、デッド４は容易に後退しない。 When the dharma 3 continues to rotate, the dead stopper 19 is guided to the middle portion 20b of the curved guide notch 20 in the middle from the unlocked state to the locked state. The inclined receiving surface 10 is pressed. That is, the operating arm 18 corresponding to the second link presses the dead bolt 4 as an auxiliary force to the drive link 5.
At the time of locking, when the drive link 5 is tilted at a predetermined position, the stopper 19 falls into the vertical portion 20c corresponding to the end point of the guide notch, and the dead 4 is prevented from moving backward. In addition, since the dead stopper 19 is suspended in a vertical state 20c, 20c of the pair of curved guide notches 20, 20 provided at least indirectly on the left and right side walls of the lock box 1, Dead 4 does not easily retreat.

本実施例の摺動部材３２は、望ましくは錠箱１の前壁１ａの内面と錠箱１の後壁１ｂの内面の間を、傾斜案内長孔４８を有するガイド板４７を介して傾方向に往復運動をする。このように構成すると、縦長の錠箱１の内部空間を有効的に活用することができる。 The sliding member 32 of the present embodiment is preferably inclined between the inner surface of the front wall 1a of the lock box 1 and the inner surface of the rear wall 1b of the lock box 1 via a guide plate 47 having an inclined guide long hole 48. Reciprocate. If comprised in this way, the internal space of the vertically long lock box 1 can be utilized effectively.

また、本実施例に於いて、ストッパレバー３３は、ストッパレバー用のバネ部材５５のバネ力によって摺動部材を係止する方向へと回転するが、もちろん、前記バネ部材５５のバネ力に代えて、磁性体の反発力により摺動部材３２を係止する方向へと回転されることもできる。磁性体の極性に基づく反発力を利用する場合には、錠箱の適宜箇所とストッパレバー３３の適宜箇所にそれぞれ磁性体が設けられる。 In this embodiment, the stopper lever 33 rotates in the direction in which the sliding member is locked by the spring force of the spring member 55 for the stopper lever. Of course, the stopper lever 33 is replaced with the spring force of the spring member 55. Thus, the sliding member 32 can be rotated in the direction of locking by the repulsive force of the magnetic body. When the repulsive force based on the polarity of the magnetic material is used, the magnetic material is provided at an appropriate location of the lock box and an appropriate location of the stopper lever 33, respectively.

また、本実施例の摺動部材３２は、望ましくはストッパレバー３３の先端部と係脱するロック部材３８を有するスライダ板３４と、このスライダ板に係合部３６を介して共働するように組み合わせられ、かつダルマ３のセクターギア２３と噛合するラックを有するラック板３５と、このラック板のバネ受け部と前記スライダ板のバネ受け部との間に組み込まれたラック板用復帰バネ４０とから成るが、摺動部材３２は、二枚の板体にせず、一枚のラック板３５にしても良い。また、ストッパレバー３３及びラック板３５の形状については、任意に設計変更することができる事項である。 Further, the sliding member 32 of the present embodiment preferably cooperates with a slider plate 34 having a lock member 38 that engages with and disengages from the distal end portion of the stopper lever 33, and the slider plate via an engaging portion 36. A rack plate 35 having a rack which is combined and meshes with the sector gear 23 of the dharma 3; and a rack plate return spring 40 incorporated between the spring receiving portion of the rack plate and the spring receiving portion of the slider plate. However, the sliding member 32 may be a single rack plate 35 instead of the two plates. Further, the shapes of the stopper lever 33 and the rack plate 35 are matters that can be arbitrarily changed in design.

さらに、特に図示しないが、ダルマ３の回動運動をデッド４の往復運動に変換する事項も、駆動リンク５に代えて、特許文献１に記載のデッドカム（ダルマ）の半径外方向に延伸する作動カムにすることもできる。 Further, although not particularly illustrated, the matter of converting the rotational movement of the dharma 3 into the reciprocating movement of the dead 4 is also an operation of extending the dead cam (dharma) described in Patent Document 1 in the radial outward direction instead of the drive link 5. It can also be a cam.

次に、図２４至図３１は、本発明の第２実施例である。この第２実施例は、トリガー１１Ａが後退動した時に、ストッパレバー３３はトリガーと共働する間接部材１２を介して回転する。間接部材１２は、トリガー１１Ａの後端部とストッパレバー３３の第１係合腕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。 Next, FIG. 24 to FIG. 31 show a second embodiment of the present invention. In the second embodiment, when the trigger 11A moves backward, the stopper lever 33 rotates via the indirect member 12 that cooperates with the trigger. The indirect member 12 is interposed between the rear end portion of the trigger 11A and the first engagement arm of the stopper lever 33 so as to be able to cooperate or link with each other.

しかして、間接部材１２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１３と、この押圧片１３に係合すると共にストッパレバー３３の第１係合腕５２と係合する可動片１４とから成る。 Thus, the indirect member 12 is engaged with, for example, a suitable pressing piece 13 in which three fingers of the right hand are expanded by a predetermined angle, and the first engaging arm 52 of the stopper lever 33 while engaging with the pressing piece 13. And a movable piece 14.

もちろん、設計如何によっては、間接部材１２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３３を確実に回転させるため、或いは戸枠Ｙの縦枠と開閉体２の縦框２ａとの間のクリアランス等を考慮して、前記押圧片１３は、例えばトリガー１１Ａが第１バネ部材１５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１１Ａの後端部の係合部１１ｄから離れる後退・回転型に構成し、また、前記３本指の可動片１４は、前記押圧片１３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 12 may be “one member” instead of a combination of a plurality of pieces. However, preferably, in order to rotate the stopper lever 33 reliably or considering the clearance between the vertical frame of the door frame Y and the vertical rod 2a of the opening / closing body 2, the pressing piece 13 is, for example, the trigger 11A. When the first spring member 15 is retracted against the spring force of the spring member 15, the first spring member 15 is configured to be a retreat / rotation type that moves away slightly from the engagement portion 11d of the rear end portion of the trigger 11A while retreating slightly. The three-finger movable piece 14 is configured as a retractable type that is displaced rearward while being pressed by the rear arm of the pressing piece 13.

ところで、押圧片１３は、中央部分１３ａから先端部へと延在しかつトリガー１１Ａの係合部１１ｄに係脱する前方アーム１３ｂと、前記中央部分１３ａから後方へと略水平状態に延在すると共に、錠箱１の一側壁の内壁面にガイド１６を介して案内されかつ可動片１４の中央部に突出形成した係合受け部１４ａに係合する後方アーム１３ｃと、前記中央部分１３ａ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１７のバネ力に抗して回転変位する上方アーム１３ｄをそれぞれ有している。その他の細部的事項は、本発明の限定要件ではないので、その詳細な説明は割愛する。 By the way, the pressing piece 13 extends from the central portion 13a to the tip portion, and extends in a substantially horizontal state from the central portion 13a to the rear, and a front arm 13b that engages with and disengages from the engaging portion 11d of the trigger 11A. In addition, a rear arm 13c that is guided to an inner wall surface of one side wall of the lock box 1 through a guide 16 and that engages with an engagement receiving portion 14a that protrudes from the central portion of the movable piece 14, and upward from the central portion 13a. And an upper arm 13d that is rotationally displaced against the spring force of the second spring member 17 that is appropriately disposed in the lock box. Since other details are not the limiting requirements of the present invention, the detailed description thereof is omitted.

なお、本実施例のトリガー（１１、１１Ａ）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Ｙ側に小突起を設けた場合には、閉戸時、トリガー（１１、１１Ａ）の先端部１１ａ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、戸枠Ｙ側に小突起を設けるのは好ましくないので、望ましくは「マグネットトリガー」を採用している。 The trigger (11, 11A) of this embodiment has a magnet at the tip regardless of its form, but when a small protrusion is provided on the door frame Y side, the trigger (11 , 11A), the tip 11a is pushed back by the small protrusion, so that the magnet is not an essential requirement. However, since it is not preferable to provide a small protrusion on the door frame Y side, a “magnet trigger” is desirably employed.
