Description

この発明は、例えば、鍵操作による施解錠(本施解錠)に加えて、鍵操作によらない簡便な施解錠(仮施解錠)をも行えるようにした引戸等の錠に関し、特に、ミニハウスや物置、倉庫、ガレージ等の組立家屋のつき合わせ引戸に用いて好適な錠に関する。   The present invention relates to, for example, a lock for a sliding door or the like that can perform simple locking / unlocking (temporary locking / unlocking) without key operation in addition to locking / unlocking by key operation (main locking / unlocking). The present invention relates to a lock suitable for use in an associative sliding door of an assembly house such as a storeroom, a warehouse, a garage, or the like.

例えば屋外に設置された物置の引戸が解錠状態である場合、引戸自体は閉まっていても風などによる少しの衝撃や振動で開くことがあり、また、使用者は引戸を閉めたつもりでいても実際は引戸自体のリバウンドで開いていることもある。そして、人目につく環境で引戸が僅かにでも開いたまま無人で放置されている状況は窃盗を誘発しかねず、物置が無人となる間に引戸を解錠状態にしてあるのは、例えそれが短時間であっても防犯上決して好ましくない。   For example, when the sliding door of a storeroom installed outdoors is unlocked, the sliding door itself may open due to a slight impact or vibration due to the wind even if it is closed, and the user intends to close the sliding door. In fact, it may be opened by rebound of the sliding door itself. And in a conspicuous environment, a situation where the sliding door is left unattended with a slight opening may induce theft, and the sliding door is unlocked while the storage is unattended. Even if it is for a short time, it is not preferable for crime prevention.

しかし、物置内外への物の入出作業を、作業者が物を抱えた状態で行ったり連続して行ったりする場合、鍵を用いた引戸の施解錠は必然的に困難化あるいは煩雑化するため、やむを得ず引戸が解錠状態のままの物置を短時間ながらも無人で放置するという状況は起こり得る。そこで、鍵操作を伴う本施解錠の他に、鍵操作が不要でワンタッチで行える仮施解錠をも可能とした錠が物置の引戸等に用いられている(特許文献1参照)。即ち、この錠を用いた物置では、夜間等の使用しない間は引戸を本施錠しておき、使用中は仮施解錠を利用することにより、高い防犯性と操作性の両立を図ることができる。   However, when an operator enters / exits an object into / out of the storage room while holding the object or continuously, it is difficult or complicated to lock and unlock the sliding door using a key. There may be a situation where the storage door is unavoidably left unattended even for a short time. Therefore, in addition to the present locking / unlocking with a key operation, a lock that allows a temporary locking / unlocking that can be performed with one touch without requiring a key operation is used for a sliding door of a storeroom (see Patent Document 1). That is, in the storeroom using this lock, it is possible to achieve both high crime prevention performance and operability by keeping the sliding door locked during the night time and the like, and using the temporary unlocking during use. .

ここで、特許文献1における本施解錠および仮施解錠は、引戸に設けた錠ケースの側面から出没する掛金と、相手方の引戸または柱に設けられ前記掛金を掛止可能な受金具とを用いて施解錠する点では共通であり、鍵を用いて本施錠した場合に仮施解錠は不能となり本解錠した場合に仮施解錠が可能となる点で両者は異なる。   Here, the present locking / unlocking and temporary locking / unlocking in Patent Document 1 uses a latch that protrudes and protrudes from the side surface of the lock case provided on the sliding door, and a receiving metal that is provided on the other party's sliding door or column and can latch the latch. The two are different in that they are common in that they are locked and unlocked, and temporary locking and unlocking is impossible when the key is locked and temporary locking and unlocking is possible when the key is unlocked.

特許第3647742号公報Japanese Patent No. 3647742

ところで、作業の容易性や明るさから来る安心感などから物置の使用は専ら日中に行われることが多いとはいえ、日中であっても物置内部は比較的暗く、物置に入って作業をしている際に、例えば子供がいたずらで外から仮施錠したり、物置内に人がいることを知らずに誤って仮施錠することが考えられる。そして、この場合、物置内に閉じ込められた人はその暗さのために錠の場所を見失うなどし、解錠操作を行うことができなくなって物置から自力で出られなくなるという事故が発生する懸念がある。   By the way, although the storage is often used only during the day because of the ease of work and the security that comes from the brightness, the interior of the storage is relatively dark even during the day, so you can work in the storage. For example, it is conceivable that a child is temporarily locked from the outside due to mischief or accidentally locked without knowing that there is a person in the storage. In this case, a person trapped in the storeroom may lose sight of the lock due to its darkness, and may not be able to perform the unlocking operation and may not be able to leave the storeroom by himself. There is.

本発明は上述の実情に鑑みてなされたもので、その目的は、暗い室内に閉じ込められた際に室外に出るために必要な引戸等の解錠操作を容易かつ確実に行うことができる錠を提供することにある。   The present invention has been made in view of the above circumstances, and its purpose is to provide a lock capable of easily and reliably performing an unlocking operation of a sliding door or the like necessary to go outside when confined in a dark room. It is to provide.

上記目的を達成するために、本発明に係る錠は、室外側から施解錠操作を行うための室外側操作部と、この室外側操作部によって施錠操作された場合にのみ室内側から解錠操作可能に構成された室内側操作部と、室外側に設けた受光部と、この受光部において受光した光を室内に導入する光導入部とを備え、この光導入部を、前記室内側操作部自体または室内側操作部の近傍に設けたことを特徴としている(請求項1)。 To achieve the above object, tablets according to the present invention, an outdoor side operation unit for performing an unlocking operation from the outdoor side, the indoor-side or et unlocking only when it is locking operation by the outdoor-side operating portion An indoor side operation unit configured to be operable, a light receiving unit provided on the outdoor side, and a light introducing unit that introduces light received by the light receiving unit into the room, the light introducing unit being used for the indoor side operation It is characterized in that it is provided in the vicinity of the section itself or the indoor side operation section (claim 1).

また、本発明では、前記室内側操作部が施錠位置と解錠位置とにわたって摺動する摘まみであり、解錠位置にある前記摘まみに対する施錠位置に摺動させるための接触を絶つ防壁を設けてある請求項1に記載の錠を提供する(請求項)。 Further, in the present invention, it is tried pinches before SL indoor side operation unit slides over the locking position and the unlocking position, barrier to break off contact for sliding the locking position relative to the knob Mi in unlocked position the providing tablet according to Oh Ru claim 1 provided (claim 2).

請求項1,2に係る発明では、暗い室内に閉じ込められた際に室外に出るために必要な引戸等の解錠操作を容易かつ確実に行うことができる錠が得られる。 According to the first and second aspects of the invention, it is possible to obtain a lock capable of easily and reliably performing an unlocking operation of a sliding door or the like necessary for exiting the room when confined in a dark room.

すなわち、請求項1に係る発明では、日中であれば、室外に比べて暗い室内からであっても前記光導入部から導入した光を頼りに室内側操作部を操作して容易に解錠することができるので、室内に閉じ込められてしまうというような事故を確実に防ぐことができる。   That is, in the invention according to claim 1, during the daytime, even in a dark room compared to the outdoors, it is easy to unlock by operating the indoor side operation unit relying on the light introduced from the light introduction unit. As a result, accidents such as being trapped in the room can be reliably prevented.

加えて、請求項1,2に係る発明では以下の効果が得られる。すなわち、室内から本施解錠操作および仮施解錠操作のすべてを行えるようにした場合には、室内が暗いと解錠操作が非常に困難になるが、請求項1,2に係る発明では、室内からは室内側操作部による解錠操作のみしか行えないようにしてあるため、解錠操作が簡単であり、上記事故の防止をより効果的に図ることができる。 In addition, the invention according to claims 1 and 2 provides the following effects. That is, when the allow all of the locking and unlocking operations and the temporary unlocking operation from the room is the room is dark and unlocking operation becomes very difficult, in the invention according to claim 1, 2, room Since only the unlocking operation by the indoor side operation unit can be performed, the unlocking operation is simple and the accident can be prevented more effectively.

以下、本発明の実施の形態について図面を参照しながら説明する。ここで、図1は本発明の一実施の形態に係る錠を設けた引戸の要部の構成を概略的に示す斜視図、図2は前記錠の施錠状態の構成を概略的に示す縦断面図、図3は前記錠の施錠状態の構成を概略的に示す部分透視正面図、図4は前記錠の解錠状態の構成を概略的に示す背面図、図5(A)および(B)は仮施錠状態の前記錠の要部の構成を概略的に示す背面図および縦断面図、図6(A)および(B)は仮解錠状態の前記錠の要部の構成を概略的に示す背面図および縦断面図、図7および図8は前記錠の仮解錠状態および仮施錠状態の構成を概略的に示す部分透視正面図、図9および図10は前記錠の本解錠状態および本施錠状態の構成を概略的に示す部分透視正面図である。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. Here, FIG. 1 is a perspective view schematically showing a configuration of a main part of a sliding door provided with a lock according to an embodiment of the present invention, and FIG. 2 is a longitudinal section schematically showing a configuration of a locked state of the lock. FIG. 3, FIG. 3 is a partially transparent front view schematically showing the configuration of the lock in a locked state, FIG. 4 is a rear view schematically showing the configuration of the lock in an unlocked state, and FIGS. 5 (A) and 5 (B). FIG. 6A is a rear view and a longitudinal sectional view schematically showing the configuration of the main part of the lock in the temporarily locked state, and FIGS. 6A and 6B are diagrams schematically showing the configuration of the main part of the lock in the temporarily unlocked state. FIG. 7 and FIG. 8 are partial perspective front views schematically showing the structure of the lock in a temporarily unlocked state and a temporarily locked state, and FIGS. 9 and 10 are the unlocked states of the lock. It is a partial see-through front view schematically showing the configuration in the locked state.

まず、本実施形態に係る錠は、図1に示すように、物置等の組立家屋の引戸1に取り付けてあり、相手側の引戸2には受金具3を設けてある。尚、本実施形態では前記錠および受金具3をつき合わせ引戸1,2に設けてあるが、いずれか一方を引戸ではなく柱に設けてあってもよい。   First, as shown in FIG. 1, the lock according to the present embodiment is attached to a sliding door 1 of an assembly house such as a storeroom, and a receiving metal fitting 3 is provided on the counterpart sliding door 2. In the present embodiment, the lock and the metal fitting 3 are provided on the sliding doors 1 and 2, but either one may be provided on a pillar instead of the sliding door.

また、図1および図2に示すように、前記錠は、引戸1の室外面側に化粧カバー4を備え、化粧カバー4の下部に設けた正面視略矩形状の開口4aからは、操作レバー5が上下に摺動可能な状態で室外側に露出し、化粧カバー4の上部に設けた正面視略円形状の開口4bからは、キー溝6aを前面に有する回動体(シリンダ)6が室外側に露出している。   As shown in FIGS. 1 and 2, the lock includes a decorative cover 4 on the outdoor surface side of the sliding door 1, and an operation lever is provided from an opening 4 a having a substantially rectangular shape in front view provided at a lower portion of the decorative cover 4. A rotating body (cylinder) 6 having a key groove 6a on the front surface is opened from a substantially circular opening 4b that is exposed to the outside of the room in a state where 5 is slidable up and down and is provided on the top of the decorative cover 4. Exposed outside.

ここで、前記操作レバー5は引戸1,2の仮施解錠をするためのものであり、操作レバー5を上下動させると、前記受金具3に掛止可能であり例えば板金材よりなる掛金7(図1および図2参照)が引戸1の側方に出没し、引戸1,2を閉じた状態で操作レバー5を上下動させれば仮施解錠することができる。   Here, the operating lever 5 is for temporarily locking and unlocking the sliding doors 1 and 2, and when the operating lever 5 is moved up and down, the operating lever 5 can be hooked on the metal fitting 3 and is a latch 7 made of, for example, a sheet metal material. Temporary locking and unlocking can be achieved by moving the operating lever 5 up and down with the sliding doors 1 and 2 closed (see FIG. 1 and FIG. 2).

また、前記回動体6は引戸1,2の本施解錠をするためのものであり、回動体6のキー溝6aに合鍵K(図2参照)を差し込んで回動操作すると前記掛金7が引戸1の側方に出没し、引戸1,2を閉じた状態で前記合鍵Kの回動操作を行えば本施解錠することができる。   The rotating body 6 is for locking and unlocking the sliding doors 1 and 2. When the key K (see FIG. 2) is inserted into the key groove 6 a of the rotating body 6 and is rotated, the latch 7 is moved to the sliding door. 1 can be locked and unlocked by rotating the key K with the sliding doors 1 and 2 closed and the sliding doors 1 and 2 closed.

すなわち、前記錠は、室外側から施解錠操作を行うための室外側操作部として前記操作レバー5および回動体6を有しているのであり、操作レバー5による仮施解錠と回動体6による本施解錠とは、施解錠のために掛金7を引戸1の側方に出没させて受金具3への掛止とその解除とを行わせる点では共通しているが、本施錠したときには仮施解錠は不可能となり、本解錠したときに仮施解錠が可能となる点で相違している。   In other words, the lock includes the operation lever 5 and the rotating body 6 as an outdoor operation unit for performing the locking / unlocking operation from the outdoor side. Locking / unlocking is common in that the latch 7 is moved in and out to the side of the sliding door 1 for locking / unlocking, and the latching / unlocking of the latch 3 is performed. Locking is not possible, and is different in that temporary unlocking is possible when this unlocking is performed.

一方、図2〜図4に示すように、前記錠は引戸1の室内面側に錠ケース8を備え、図3に示すように、この錠ケース8は、背壁8aと、左右壁8b,8cと、底壁8dとを有し、前側および上側には壁が無く、前側には前記化粧カバー4が装着される。そして、前記掛金7の出没作動(回動)を妨げないように、左壁8bの前部中央には切り欠き部8eを設けてある。   On the other hand, as shown in FIGS. 2 to 4, the lock includes a lock case 8 on the indoor surface side of the sliding door 1. As shown in FIG. 3, the lock case 8 includes a back wall 8 a, left and right walls 8 b, 8c and bottom wall 8d, there are no walls on the front side and the upper side, and the decorative cover 4 is mounted on the front side. A notch 8e is provided in the center of the front portion of the left wall 8b so as not to hinder the operation (rotation) of the latch 7.

また、図2、図4並びに図5(A)および(B)に示すように、前記錠ケース8の背壁8aには、上から順に、背面が平らな上背壁部9と、背面が下側ほど奥まるように湾曲している湾曲壁部10と、背面が平らで湾曲壁部10との境界部分に段部11aを有する下背壁部11とを設けてあり、湾曲壁部10の下部から下背壁部11の上部にかけて背面視略矩形状の開口12を形成してある。そして、この開口12からは、摘まみ13が上下に摺動可能な状態で室内側に露出しており、この摘まみ13は下背壁部11の背面よりも後ろ側(室内側)へ突出しないように構成してある。   As shown in FIGS. 2, 4, 5 (A) and 5 (B), the back wall 8 a of the lock case 8 has an upper back wall portion 9 having a flat back surface and a back surface in order from the top. A curved wall portion 10 that is curved so as to be deeper toward the lower side, and a lower back wall portion 11 that has a flat back surface and has a step portion 11a at a boundary portion between the curved wall portion 10 and the curved wall portion 10. An opening 12 having a substantially rectangular shape in rear view is formed from the lower part to the upper part of the lower back wall part 11. The knob 13 is exposed to the indoor side in a state where the knob 13 is slidable up and down, and the knob 13 protrudes rearward (indoor side) from the back surface of the lower back wall portion 11. It is configured not to.

ここで、図2、図5(B)および図6(B)に示すように、摘まみ13は前記操作レバー5と一体的に形成してあり、上述のように仮施解錠のために操作レバー5を上下動させると、図5(A)、(B)並びに図6(A)、(B)に示すように、摘まみ13も同じく上下動することになる。   Here, as shown in FIG. 2, FIG. 5 (B) and FIG. 6 (B), the knob 13 is formed integrally with the operation lever 5, and is operated for temporary locking and unlocking as described above. When the lever 5 is moved up and down, as shown in FIGS. 5A and 5B and FIGS. 6A and 6B, the knob 13 also moves up and down.

しかし、前記操作レバー5は上下動(仮施解錠)操作が可能であるのに対して、摘まみ13は、図5(A)および(B)に示す施錠位置から図6(A)および(B)に示す解錠位置へと摺動(下動)させる仮解錠操作のみが可能となっている。その構造を具体的に述べると、図2、図4〜図6に示すように、前記下背壁部11の段部11aの中央には前記摘まみ13を受け入れる凹入部11bを設けてあり、解錠位置にある摘まみ13は凹入部11bによってその左右両方および下方の三方が囲まれ、摘まみ13の左右両側面および下面に触れることができない状態となる。換言すれば、前記凹入部11bを有する下背壁部11は、解錠位置にある前記摘まみ13に対する施錠位置に摺動(上動)させるための接触を絶つ防壁となっている。   However, the operation lever 5 can be moved up and down (temporary locking / unlocking), whereas the knob 13 is moved from the locking position shown in FIGS. 5 (A) and 5 (B) to FIGS. Only a temporary unlocking operation that slides (downward) to the unlocking position shown in B) is possible. Specifically, as shown in FIGS. 2 and 4 to 6, the structure is provided with a recessed portion 11 b for receiving the knob 13 at the center of the step portion 11 a of the lower back wall portion 11. The knob 13 in the unlocked position is surrounded by the recessed portion 11b on both the left and right sides and the lower three sides, so that the left and right sides and the lower surface of the knob 13 cannot be touched. In other words, the lower back wall portion 11 having the recessed portion 11b serves as a barrier that prevents contact for sliding (upward movement) to the locking position with respect to the knob 13 in the unlocking position.

要するに、前記錠は、室内側から解錠操作を行うための室内側操作部として前記摘まみ13を設けてあり、この摘まみ13による施錠(仮施錠および本施錠)操作を不可能としてある上、摘まみ13により行える解錠操作は仮解錠操作のみであって本解錠操作は不可能である。   In short, the lock is provided with the knob 13 as an indoor side operation unit for performing an unlocking operation from the indoor side, and locking (temporary locking and main locking) operation by the knob 13 is impossible. The unlocking operation that can be performed by the knob 13 is only a temporary unlocking operation, and this unlocking operation is impossible.

次に、上述した仮施解錠をするための前記錠の具体的な構造について説明する。まず、図2および図3に示すように、前記錠ケース8内には、フレーム構造のシフター14を上下に摺動可能に収納してあり、このシフター14は、図3に示すように、錠ケース8の上方に突出する頭部15と、この頭部15の左右から垂下する二つの垂下部16,17と、二つの垂下部16,17の下部間に架設したブリッジ18とを備えている。そして、ブリッジ18の前後に前記操作レバー5および摘まみ13を連設してある。ここで、シフター14は錠ケース8の背壁8aに沿わせて配置してあるので、錠ケース8の左壁8bの切り欠き部8eの内側をシフター14の垂下部16が塞いで掛金7の回動を妨げるということはない。   Next, a specific structure of the lock for performing the above-described temporary locking and unlocking will be described. First, as shown in FIGS. 2 and 3, a frame-structured shifter 14 is accommodated in the lock case 8 so as to be slidable in the vertical direction. As shown in FIG. A head 15 protruding above the case 8, two hanging parts 16, 17 hanging from the left and right of the head 15, and a bridge 18 constructed between the lower parts of the two hanging parts 16, 17 are provided. . The operation lever 5 and the knob 13 are connected to the front and rear of the bridge 18. Here, since the shifter 14 is arranged along the back wall 8a of the lock case 8, the hanging portion 16 of the shifter 14 closes the inside of the notch 8e of the left wall 8b of the lock case 8, and the latch 7 There is no impediment to rotation.

尚、前記シフター14の頭部15は摘まみ13とともに上下動し、かつ錠ケース8の上方に突出(露出)しているので、理論的にはこの頭部15を上下動操作することによっても仮施解錠することができる。しかし、図3に示すように、前記頭部15の背面視は上側ほど細くなる台形状あるいは山状であって、頭部15は手あるいは指で掴みにくい構造となっているので、頭部15の押し下げ操作(仮解錠操作)は可能であるが、頭部15を掴む必要のある引き上げ操作(仮施錠操作)は不可能となっている。すなわち、頭部15も摘まみ13と同様に、室内側から解錠操作を行うための室内側操作部に該当し、頭部15による施錠(仮施錠および本施錠)操作を不可能としてある上、頭部15により行える解錠操作は仮解錠操作のみであって本解錠操作は不可能である。   Since the head 15 of the shifter 14 moves up and down together with the knob 13 and protrudes (exposes) above the lock case 8, theoretically, the head 15 can be moved up and down. Temporary locking and unlocking can be performed. However, as shown in FIG. 3, the back view of the head 15 has a trapezoidal shape or a mountain shape that becomes thinner toward the upper side, and the head 15 has a structure that is difficult to grasp with a hand or a finger. Can be pushed down (temporary unlocking operation), but a lifting operation (temporary locking operation) that needs to hold the head 15 is impossible. That is, similarly to the knob 13, the head 15 corresponds to an indoor operation unit for performing an unlocking operation from the indoor side, and locking (temporary locking and permanent locking) operation by the head 15 is impossible. The unlocking operation that can be performed by the head 15 is only a temporary unlocking operation, and this unlocking operation is impossible.

また、前記操作レバー5および摘まみ13を有するシフター14全体は、例えば透明または半透明の合成樹脂等、光透過性を有する部材により構成してある。   Further, the entire shifter 14 having the operation lever 5 and the knob 13 is formed of a light-transmitting member such as a transparent or translucent synthetic resin.

そして、掛金7は、図2および図3に示すように、支軸19により錠ケース8の背壁8aに回動自在に支持されている。また、図2および図3に示すように、掛金7の背面には突起20を設けてあり、この突起20はシフター14の垂下部16に設けた二つの係止爪21,22に係合可能となっている。さらに、図2および図3に示すように、掛金7の背面および錠ケース8の背壁8a前面の適宜位置に凸部23,24を設けてあり、これらの凸部23,24につる巻きばね25を掛張してある。   As shown in FIGS. 2 and 3, the latch 7 is rotatably supported on the back wall 8 a of the lock case 8 by a support shaft 19. As shown in FIGS. 2 and 3, a protrusion 20 is provided on the back surface of the latch 7, and this protrusion 20 can be engaged with two locking claws 21 and 22 provided on the hanging portion 16 of the shifter 14. It has become. Further, as shown in FIGS. 2 and 3, convex portions 23 and 24 are provided at appropriate positions on the back surface of the latch 7 and the front surface of the back wall 8 a of the lock case 8, and a helical spring that hangs on these convex portions 23 and 24. 25 is hung.

続いて、上記構成を備えた錠の仮施解錠時の作動について説明する。まず、図7に示すように、錠が仮解錠状態にあるときには、操作レバー5および摘まみ13を有するシフター14はその摺動範囲における最下位置にあり、掛金7は前記つる巻きばね25により図7に示す退没位置に止まるように付勢されている。   Then, the operation | movement at the time of temporary locking / unlocking of the lock | rock provided with the said structure is demonstrated. First, as shown in FIG. 7, when the lock is in a temporarily unlocked state, the shifter 14 having the operation lever 5 and the knob 13 is at the lowest position in the sliding range, and the latch 7 is the helical spring 25. Therefore, it is urged to stop at the retracted position shown in FIG.

そして、仮施錠のために操作レバー5を解錠位置(図7参照)から施錠位置(図8参照)に摺動させると、操作レバー5と一体のシフター14も上方に摺動する。そして、このとき、シフター14の下方の係止爪22が掛金7の突起20を押し上げ、掛金7は支軸19を中心に図7において時計回りに約90度回転する。   When the operating lever 5 is slid from the unlocked position (see FIG. 7) to the locked position (see FIG. 8) for temporary locking, the shifter 14 integrated with the operating lever 5 also slides upward. At this time, the locking claw 22 below the shifter 14 pushes up the protrusion 20 of the latch 7, and the latch 7 rotates about 90 degrees clockwise around the support shaft 19 in FIG.

上記の操作により錠が仮施錠状態になると、図8に示すように、シフター14はその摺動範囲における最上位置に位置するとともに、掛金7は前記つる巻きばね25により図8に示す進出位置に止まるように付勢されることになる。   When the lock is temporarily locked by the above operation, as shown in FIG. 8, the shifter 14 is positioned at the uppermost position in the sliding range, and the latch 7 is moved to the advanced position shown in FIG. 8 by the helical spring 25. It will be energized to stop.

また、逆に、仮解錠のために操作レバー5または摘まみ13を施錠位置(図8参照)から解錠位置(図7参照)に摺動させると、操作レバー5と一体のシフター14も下方に摺動する。そして、このとき、シフター14の上方の係止爪21が掛金7の突起20を押し下げ、掛金7は支軸19を中心に図8において反時計回りに約90度回転し、錠は図7に示す仮解錠状態に戻る。   Conversely, when the operating lever 5 or the knob 13 is slid from the locking position (see FIG. 8) to the unlocking position (see FIG. 7) for temporary unlocking, the shifter 14 integrated with the operating lever 5 is also moved. Slide down. At this time, the locking claw 21 above the shifter 14 pushes down the projection 20 of the latch 7, and the latch 7 rotates about 90 degrees counterclockwise in FIG. It returns to the temporary unlocking state shown.

次に、上述した本施解錠をするための前記錠の具体的な構造について説明する。尚、この本施解錠するための構造は仮施解錠するための上記の構造を一部に利用するものであり、既に説明した部材についての重複する説明は以下では省略してある。   Next, a specific structure of the lock for performing the above-described locking and unlocking will be described. In addition, this structure for locking / unlocking uses the above-described structure for temporary locking / unlocking in part, and redundant description of the members already described is omitted below.

まず、図3に二点鎖線で示すように、前記錠ケース8の背壁8a上部の前面に支持部材26をねじ止めで固定してあり、この支持部材26により前記回動体6(図3参照)を支持してある。ここで、支持部材26は、キー溝6aに挿入した合鍵Kによってのみ回動体6を回動操作すことができるように回動体6を支持している。   First, as shown by a two-dot chain line in FIG. 3, a support member 26 is fixed to the front surface of the upper portion of the back wall 8a of the lock case 8 with screws, and the rotating member 6 (see FIG. 3) is supported by the support member 26. ) Is supported. Here, the support member 26 supports the rotating body 6 so that the rotating body 6 can be rotated only by the key K inserted in the key groove 6a.

また、図3に示すように、前記錠ケース8の背壁8a前面に沿わせて摺動子27を収納してあり、この摺動子27は背壁8aに設けたガイド28,29に案内されて上下に摺動可能となっている。さらに、図2に示すように、前記支持部材26により支持された回動体6と錠ケース8の背壁8aとの間には、摺動子27を上下に挿通させるための隙間を設けてあると共に、図2および図3に示すように、回動体6の背面には、摺動子27の上部に設けた横長の溝27aに係止する係止突起6bを設けてある。   As shown in FIG. 3, a slider 27 is accommodated along the front surface of the back wall 8a of the lock case 8, and the slider 27 is guided to guides 28 and 29 provided on the back wall 8a. It is possible to slide up and down. Further, as shown in FIG. 2, a gap is provided between the rotating body 6 supported by the support member 26 and the back wall 8a of the lock case 8 so that the slider 27 can be inserted vertically. In addition, as shown in FIGS. 2 and 3, a locking protrusion 6 b that locks in a horizontally long groove 27 a provided on the upper portion of the slider 27 is provided on the back surface of the rotating body 6.

一方、図3中の拡大図に詳しく示すように、摺動子27の下部左側には中空ブロック30を設けてあり、この中空ブロック30は、摺動ピン31と、ピンガイド32とを保持するものである。詳述すると、摺動ピン31は小径部31aと大径部31bとを有し、ピンガイド32は一端が閉塞された略筒状の部材であり、ピンガイド32の内部に摺動ピン31の大径部31bが挿入されている。また、中空ブロック30には摺動ピン31の小径部31aが挿通する小孔30aと、ピンガイド32が挿入される大孔30bとを設けてあると共に、大孔30b内には摺動ピン31の大径部31bを図3において右方向に付勢する第1ばね33を収容してある。さらに、ピンガイド32内にはピン31の大径部31bを図3において左方向に付勢する第2ばね34を設けてあり、この第2ばねのばね定数は第1ばねのばね定数よりも大となっている。   On the other hand, as shown in detail in the enlarged view of FIG. 3, a hollow block 30 is provided on the lower left side of the slider 27, and the hollow block 30 holds a sliding pin 31 and a pin guide 32. Is. More specifically, the sliding pin 31 has a small-diameter portion 31 a and a large-diameter portion 31 b, and the pin guide 32 is a substantially cylindrical member with one end closed, and the sliding pin 31 is placed inside the pin guide 32. The large diameter part 31b is inserted. The hollow block 30 is provided with a small hole 30a through which the small diameter portion 31a of the sliding pin 31 is inserted, and a large hole 30b into which the pin guide 32 is inserted, and the sliding pin 31 is inserted into the large hole 30b. The first spring 33 for urging the large-diameter portion 31b in the right direction in FIG. 3 is accommodated. Further, a second spring 34 for urging the large diameter portion 31b of the pin 31 leftward in FIG. 3 is provided in the pin guide 32. The spring constant of the second spring is larger than the spring constant of the first spring. It has become big.

他方、図3に示すように、摺動子27の下部右側には摺動カム35を枢支してあると共に、摺動子27の摺動時に摺動カム35に当接してこれを回動させるガイド36を錠ケース8の背壁8a前面に突設してある。   On the other hand, as shown in FIG. 3, a sliding cam 35 is pivotally supported on the lower right side of the slider 27 and abuts against the sliding cam 35 when the slider 27 slides. A guide 36 is provided on the front surface of the back wall 8 a of the lock case 8.

さらに、図9および図10に示すように、シフター14の垂下部16には前記摺動ピン31の動きを規制する規制部37を設けてあり、この規制部37の中央には前記摺動ピン31の進出を許容する切り欠き部分37aを形成してある。   Further, as shown in FIGS. 9 and 10, the hanging portion 16 of the shifter 14 is provided with a regulating portion 37 that regulates the movement of the sliding pin 31, and the sliding pin 37 is provided at the center of the regulating portion 37. A cutout portion 37 a that allows 31 to advance is formed.

続いて、上記構成を備えた錠の本施解錠時の作動について説明する。まず、図9に錠の本解錠状態を示しているが、錠の本解錠状態と仮解錠状態とは同一であり、シフター14および掛金7は図7に示す状態と同じ状態にある。また、図9に示すように、錠が本解錠状態にあるときには、回動体6は係止突起6bが最下位置にある状態となっていると共に、摺動カム35にガイド36が当接せず、摺動ピン31は中空ブロック30内に収容された状態となっている。   Then, the operation | movement at the time of this locking / unlocking of the lock | rock provided with the said structure is demonstrated. First, the final unlocked state of the lock is shown in FIG. 9, but the final unlocked state and the temporary unlocked state of the lock are the same, and the shifter 14 and the latch 7 are in the same state as shown in FIG. . As shown in FIG. 9, when the lock is in the fully unlocked state, the rotating body 6 is in a state where the locking projection 6 b is at the lowest position, and the guide 36 abuts against the sliding cam 35. Instead, the sliding pin 31 is housed in the hollow block 30.

そして、本施錠のためにキー溝6aに挿入した合鍵Kを例えば時計回りに約180度回転させると、回動体6も同方向に約180度回転し、図10に示すように回動体6の係止突起6bが最上位置に移動する。そして、この移動に伴い、係止突起6bに係止する溝27aを有する摺動子27が上方に摺動し、この摺動に伴い、ガイド36が摺動カム35に当接しこれを図9において時計回りに回動させる。さらに、摺動カム35はピンガイド32を図9において左方向に付勢するので、図10に示すように、摺動ピン31が規制部37の切り欠き部分37a内に進出し、さらにこの規制部37に係止して規制部37を有するシフター14全体を持ち上げる。   Then, when the joint key K inserted into the keyway 6a for this locking is rotated, for example, about 180 degrees clockwise, the rotating body 6 also rotates about 180 degrees in the same direction, as shown in FIG. The locking projection 6b moves to the uppermost position. With this movement, the slider 27 having the groove 27a that engages with the engaging projection 6b slides upward. With this sliding, the guide 36 abuts against the sliding cam 35, which is shown in FIG. And rotate clockwise. Further, since the sliding cam 35 urges the pin guide 32 to the left in FIG. 9, the sliding pin 31 advances into the notch 37a of the restricting portion 37 as shown in FIG. The entire shifter 14 having the restricting portion 37 engaged with the portion 37 is lifted.

上記の操作により錠が本施錠状態になると、図10に示すように、シフター14はその摺動範囲における最上位置に位置するとともに、掛金7は前記つる巻きばね25により図8に示す進出位置に止まるように付勢されることになる。そして、この本施錠状態では、シフター14に設けた規制部37が前記摺動ピン31の係止により下がらなくなっているため、シフター14に一体化してある操作レバー5および摘まみ13の押し下げ操作、すなわち仮解錠操作は不可能となっている。   When the lock is brought into the final locked state by the above operation, as shown in FIG. 10, the shifter 14 is positioned at the uppermost position in the sliding range, and the latch 7 is moved to the advanced position shown in FIG. It will be energized to stop. In this locked state, the restricting portion 37 provided on the shifter 14 is not lowered due to the locking of the sliding pin 31, so that the operation lever 5 and the knob 13 that are integrated with the shifter 14 are pushed down. That is, temporary unlocking operation is impossible.

また、逆に、本解錠のためにキー溝6aに挿入した合鍵Kを例えば反時計回りに約180度回転させると、回動体6も同方向に約180度回転し、図9に示すように回動体6の係止突起6bが最下位置に移動する。そして、この移動に伴い、係止突起6bに係止する溝27aを有する摺動子27が下方に摺動し、この摺動に伴い、摺動ピン31が規制部37を有するシフター14全体を押し下げた後、ガイド36が摺動カム35から離間するので、摺動カム35によるピンガイド32の上記付勢が解除され、錠は図9に示す本解錠状態に戻る。   Conversely, when the key K inserted in the keyway 6a for the unlocking is rotated, for example, approximately 180 degrees counterclockwise, the rotating body 6 is also rotated approximately 180 degrees in the same direction, as shown in FIG. Then, the locking projection 6b of the rotating body 6 moves to the lowest position. Then, along with this movement, the slider 27 having the groove 27a that engages with the engaging projection 6b slides downward. With this sliding, the sliding pin 31 moves the entire shifter 14 having the restricting portion 37. Since the guide 36 is separated from the sliding cam 35 after being pushed down, the urging of the pin guide 32 by the sliding cam 35 is released, and the lock returns to the fully unlocked state shown in FIG.

上記の構成を有する錠では、前記シフター14を光透過性の部材によって形成してあるので、室外側に設けた操作レバー5が受光部として機能し、前記シフター14が操作レバー5において受光した光を室内側に伝達する光伝達部として機能し、摘まみ13が前記光を室内に導入する光導入部として機能することになる。従って、日中であれば、室外に比べて暗い室内からであっても前記摘まみ13から導入した光を頼りに摘まみ13を操作して容易に解錠することができるので、室内に閉じ込められてしまうというような事故を確実に防ぐことができる。   In the lock having the above configuration, since the shifter 14 is formed of a light transmissive member, the operation lever 5 provided on the outdoor side functions as a light receiving portion, and the light received by the shifter 14 at the operation lever 5 The knob 13 functions as a light introducing part for introducing the light into the room. Therefore, during daytime, even if the room is darker than outdoors, it can be easily unlocked by operating the knob 13 with the help of the light introduced from the knob 13, so that it can be locked in the room. Accidents such as being accidentally prevented can be reliably prevented.

また、上記の構成を備えた錠では、室内からは摘まみ13あるいはシフター14の頭部15を用いた仮解錠操作のみしか行えないようにしてあるため、解錠操作が簡単であり、上記事故の防止をより効果的に図ることができる。   Further, in the lock having the above-described configuration, since only the temporary unlocking operation using the knob 13 or the head 15 of the shifter 14 can be performed from the room, the unlocking operation is simple. Accidents can be prevented more effectively.

なお、本発明の錠は、上記の実施の形態に限られず、種々に変形して実施することができる。例えば、上記実施の形態では、光導入部として前記摘まみ13のみを設けてあるが、摘まみ13の近傍に別途光導入部を設けてあってもよい。すなわち、前記錠に、室外側に設けた受光部と、この受光部において受光した光を室内に導入する光導入部とを設け、この光導入部を、前記室内側操作部自体または室内側操作部の近傍に設けてあればよく、受光部、光導入部の具体的な構成は種々のものを採用することができる。その一例としては、前記化粧カバー4および錠ケース8の全体を光透過性を有する部材で形成することが挙げられる。   In addition, the lock | rock of this invention is not restricted to said embodiment, It can implement in various deformation | transformation. For example, in the above embodiment, only the knob 13 is provided as the light introducing part, but a light introducing part may be provided separately in the vicinity of the knob 13. That is, the lock is provided with a light receiving portion provided outside the room and a light introducing portion that introduces light received by the light receiving portion into the room, and the light introducing portion is connected to the indoor side operation unit itself or the indoor side operation. As long as it is provided in the vicinity of the unit, various configurations of the light receiving unit and the light introducing unit may be employed. As an example, it is possible to form the entire decorative cover 4 and the lock case 8 with a light-transmitting member.
