As this auxiliary lock, a locking member holding piece that protrudes in the opening direction of the swinging door is attached to the door frame side of the swinging door, a locking member is attached to this locking member holding piece, and this locking member is brought into contact with the swinging door from the outside. An auxiliary lock is known that performs locking by locking the vehicle (for example, see Patent Document 1).

ところで、特許文献１に記載の補助錠は、外開き式の開き戸用のもので、内開き式の開き戸には適用できないということに加え、以下の使用形態において、補助錠の施錠時に室内からの緊急脱出ができないという問題があった。 By the way, the auxiliary lock described in Patent Document 1 is for an outward-opening type of hinged door, and cannot be applied to an inward-opening type of hinged door. In addition, in the following usage pattern, when the auxiliary lock is locked, there is There was a problem in that emergency evacuation was not possible.

すなわち、不動産業、ビル管理会社等（本明細書において、「管理者」という。）の管理物件（本明細書において、「空き部屋」という。）の場合、空き部屋の内開き式の開き戸の錠前の鍵は防犯上管理者が管理し、空き部屋は錠前を開けた状態で、管理者や工事業者等は、空き部屋に管理錠として補助錠を取り付け、入居者が決まった時点で空き部屋も補助錠を外し、管理者が管理している鍵を入居者に渡す。 In other words, in the case of properties (herein referred to as ``vacant rooms'') managed by real estate companies, building management companies, etc. (herein referred to as ``managers''), the opening of the inward-opening door of the vacant room. The lock keys are managed by the manager for security reasons, and the locks of vacant rooms are left unlocked.The manager or construction contractor installs an auxiliary lock in the vacant room as a control lock, and when a tenant is decided, the vacant room is unlocked. The tenant also removes the auxiliary lock and hands the key, which is controlled by the manager, to the resident.

このような補助錠の使用形態において、例えば、空き部屋の隣の入居中の物件において火災が発生し、かつ、玄関から逃げることができない状況が生じた場合、ベランダから遮蔽壁を蹴り破り、空き部屋を通って避難することになるが、補助錠の施錠時には、室内から解錠することができないため、緊急脱出ができない。 In this type of use of auxiliary locks, for example, if a fire breaks out in a occupied property next to a vacant room and it is impossible to escape from the front door, the shielding wall is kicked from the balcony and the vacant room is opened. You will have to evacuate through the room, but when the auxiliary lock is locked, you cannot unlock it from inside the room, so you cannot make an emergency escape.

以下、本発明の補助錠の実施の形態を図面に基づいて説明する。 Hereinafter, embodiments of the auxiliary lock of the present invention will be described based on the drawings.

図１～図６に、本発明の補助錠の一実施例を示す。
この補助錠は、内開き式の開き戸１に、外方向に突出する施錠部材保持片３を取付部４を介して取り付け、この施錠部材保持片３の先端側に施錠部材５を装着し、この施錠部材５を戸枠２側に当接させることにより施錠を行うように構成されている。 1 to 6 show an embodiment of the auxiliary lock of the present invention.
In this auxiliary lock, a locking member holding piece 3 that protrudes outward is attached to an inward-opening hinged door 1 via a mounting part 4, a locking member 5 is attached to the tip side of this locking member holding piece 3, and this It is configured to lock by bringing the locking member 5 into contact with the door frame 2 side.

取付部４は、取付部本体４１に配設したナット４２ｂに螺合するねじボルト４２ａの先端に挟持片４３を取り付け、これにより、ねじボルト４２ａを回転操作することにより軸方向に出没させることで挟持片４３を移動させ、挟持片４３と施錠部材保持片３とで、開き戸１を挟持し、補助錠を開き戸１に固定することができるようにしている。
なお、挟持片４３は、本体部４３ａとゴムパッキン４３ｂとで構成するようにしている。 The mounting part 4 is constructed by attaching a clamping piece 43 to the tip of a threaded bolt 42a that is screwed into a nut 42b provided on the mounting part main body 41, so that the threaded bolt 42a can be made to protrude and retract in the axial direction by rotating the threaded bolt 42a. By moving the clamping piece 43, the clamping piece 43 and the locking member holding piece 3 clamp the hinged door 1, so that the auxiliary lock can be fixed to the hinged door 1.
Note that the holding piece 43 is composed of a main body portion 43a and a rubber packing 43b.

ところで、本実施例の補助錠は、施錠部材保持片３と取付部４とを室内側で分離可能に構成することにより、施錠部材５が施錠状態のときに、施錠部材保持片３と取付部４とを室内側で分離して解錠することができるようにしている。 By the way, in the auxiliary lock of this embodiment, the locking member holding piece 3 and the mounting part 4 are configured to be separable on the indoor side, so that when the locking member 5 is in the locked state, the locking member holding piece 3 and the mounting part 4 are separated. 4 can be separated and unlocked indoors.

施錠部材保持片３と取付部４とを室内側で分離可能にする機構として、具体的には、取付部４にカム４４をばね４５の付勢力に抗して引き操作可能に配設し、図３（ａ）に示すよう、カム４４の係止部４４ａを施錠部材保持片３の基端側に形成した係止孔３２に係合させることにより、施錠部材保持片３に取付部４を一体化させるようにするとともに、図３（ｂ）に示すよう、カム４４をばね４５の付勢力に抗して引き操作することにより、カム４４の係止部４４ａと、施錠部材保持片３の基端側に形成した係止孔３２との係合を解除し、この状態でドアノブ６を持って開き戸１を引き操作することにより、施錠部材保持片３と取付部４とを室内側で分離することができるようにしている。 Specifically, as a mechanism for making it possible to separate the locking member holding piece 3 and the attachment part 4 on the indoor side, a cam 44 is disposed on the attachment part 4 so as to be able to be pulled against the biasing force of a spring 45. As shown in FIG. 3(a), by engaging the locking portion 44a of the cam 44 with the locking hole 32 formed on the base end side of the locking member holding piece 3, the mounting portion 4 is attached to the locking member holding piece 3. In addition, by pulling the cam 44 against the biasing force of the spring 45 as shown in FIG. 3(b), the locking portion 44a of the cam 44 and the locking member holding piece 3 are separated. By releasing the engagement with the locking hole 32 formed on the base end side and in this state, holding the doorknob 6 and pulling the swinging door 1, the locking member holding piece 3 and the mounting part 4 are separated on the indoor side. I'm trying to be able to do that.

この場合、カム４４の引き操作は、リング部材４６によって行うようにするとともに、施錠部材保持片３には、操作方法（例えば、「非常脱出機能付リングを蝶番側に引き扉を開く」等）を記載した指示シール４７を貼付するようにしている。 In this case, the pulling operation of the cam 44 is performed by the ring member 46, and the locking member holding piece 3 is provided with an operation method (for example, ``Pull the ring with emergency escape function to the hinge side to open the door'', etc.) An instruction sticker 47 containing the following information is attached.

また、取付部４の取付部本体４１は、カバー４１ａで覆うことにより組み立てるようにする。 Moreover, the mounting part main body 41 of the mounting part 4 is assembled by covering it with a cover 41a.

一方、施錠部材５は、図３に示すように、直方体状の本体５０に、錠機構として、シリンダ錠５１と、シリンダ錠５１と反対側に形成され、施錠部材保持片３が挿入されるスリット状の穴５２とを有し、シリンダ錠５１に鍵５４を差し込んで回すことにより、スリット状の穴５２の奥に出没可能に設けられたラッチボール（図示省略）を突出状態で固定するように構成されている。
そして、スリット状の穴５２に挿入された施錠部材保持片３の透孔３１を、ラッチボールで係止することにより、施錠部材保持片３に施錠できるように構成されている。
このように、施錠部材５に施錠部材保持片３が挿入されるスリット状の穴５２を形成し、スリット状の穴５２の奥に出没可能に設けられたラッチボールを突出状態で固定するようにしているので、ラッチボールが外部に露出せず、このため、不正開錠がされにくいという利点がある。 On the other hand, as shown in FIG. 3, the locking member 5 has a cylinder lock 51 as a locking mechanism in a rectangular parallelepiped main body 50, and a slit formed on the opposite side of the cylinder lock 51 into which the locking member holding piece 3 is inserted. By inserting a key 54 into the cylinder lock 51 and turning it, a latch ball (not shown) provided in the slit-shaped hole 52 so as to be retractable is fixed in a protruding state. It is configured.
The locking member holding piece 3 can be locked by locking the through hole 31 of the locking member holding piece 3 inserted into the slit-shaped hole 52 with a latch ball.
In this way, a slit-like hole 52 into which the locking member holding piece 3 is inserted is formed in the locking member 5, and the latch ball, which is provided so as to be retractable in the depths of the slit-like hole 52, is fixed in a protruding state. Since the latch ball is not exposed to the outside, there is an advantage that it is difficult for unauthorized opening of the lock.

ここで、施錠部材５には、施錠部材５を施錠部材保持片３に施錠したときに、施錠部材５が戸枠２側に当接させることにより施錠を行うようにするために、戸枠当接片５３を配設するようにする。
戸枠当接片５３には、施錠時の戸枠当接片５３と戸枠２との隙間をなくすように調整する隙間調整部材５３ａを配設するとともに、開き戸１の表面に当接する扉当接片５３ｂを形成するようにする。
ここで、隙間調整部材５３ａを配設することにより、施錠時の開き戸１のがたつきを防止することができる。
また、扉当接片５３ｂを形成することにより、施錠部材５を施錠した施錠部材保持片３の先端部を蝶番側に折り曲げにくくすることで、施錠部材保持片３の先端部を折り曲げて施錠部材５の戸枠２側への当接状態を解除する不正解錠を防止することができる。 Here, the locking member 5 is provided with a door frame contact plate so that when the locking member 5 is locked to the locking member holding piece 3, the locking member 5 is brought into contact with the door frame 2 side to perform locking. A contact piece 53 is arranged.
The door frame abutting piece 53 is provided with a gap adjustment member 53a that adjusts to eliminate the gap between the door frame abutting piece 53 and the door frame 2 when the door is locked, and a door abutment that abuts the surface of the hinged door 1. A contact piece 53b is formed.
Here, by disposing the gap adjustment member 53a, it is possible to prevent the hinged door 1 from shaking when it is locked.
In addition, by forming the door abutting piece 53b, the tip of the locking member holding piece 3 that locks the locking member 5 is made difficult to bend toward the hinge side. It is possible to prevent unauthorized unlocking of the door frame 5 from contacting the door frame 2 side.

この補助錠は、施錠部材５が施錠状態のときに、施錠部材保持片３と取付部４を室内側で分離して解錠することができ、これにより、内開き式の開き戸１の後付けの補助錠として使用でき、かつ、施錠時の室内からの緊急脱出を可能にすることができるため、安全性の高い補助錠とすることができる。
そして、特に、引き操作という簡易な操作によって、施錠部材保持片３と取付部４を室内側で分離して解錠することができ、施錠時の室内からの緊急脱出を可能にすることができるため、安全性を一層向上することができる。 With this auxiliary lock, when the locking member 5 is in the locked state, the locking member holding piece 3 and the mounting part 4 can be separated and unlocked on the indoor side. Since it can be used as an auxiliary lock and allows emergency escape from the room when the lock is locked, it can be a highly safe auxiliary lock.
In particular, by a simple pulling operation, the locking member holding piece 3 and the attachment part 4 can be separated and unlocked on the indoor side, making it possible to make an emergency escape from the room when the door is locked. Therefore, safety can be further improved.

以上、本発明の補助錠について、その実施例に基づいて説明したが、本発明は上記実施例に記載した構成に限定されるものではなく、施錠部材保持片３と取付部４とを室内側で分離可能にする機構として、例えば、引き抜きピンによる連結構造を採用するようにする等、その趣旨を逸脱しない範囲において適宜その構成を変更することができる。 The auxiliary lock of the present invention has been described above based on the embodiments thereof, but the present invention is not limited to the configuration described in the above embodiments. The structure can be changed as appropriate without departing from the spirit of the invention, such as by employing a connection structure using a pull-out pin as the mechanism that allows the parts to be separated.

本発明の補助錠は、内開き式の開き戸の後付けの補助錠として使用でき、かつ、施錠時の室内からの緊急脱出を可能にしたものであることから、空き部屋の管理錠としての用途に好適に用いることができるほか、内開き式の開き戸の補助錠としての用途に広く用いることができる。 The auxiliary lock of the present invention can be used as a retrofitted auxiliary lock for an inward-opening door, and also enables emergency escape from the room when the door is locked, so it can be used as a management lock for vacant rooms. In addition to being suitable for use, it can also be widely used as an auxiliary lock for inward-opening doors.
