Description

この発明は、鞄や保管ボックス等に用いるのに好適な施錠装置に関する。   The present invention relates to a locking device suitable for use in a bag or a storage box.

一般に、施錠装置は、下記特許文献１に記載されているように、鞄等の本体部に取り付けられるケースと、鞄等のカバー部に取り付けられる係合体とを備えている。ケースの一側部には、当該一側部を貫通する切欠き部が形成されている。一方、係合体には、切欠き部を通ってケース内に出没可能な係止片部が設けられている。そして、ケース内に挿入された係止片部をケースから脱出不能に係止するとともに、その係止状態を維持するために、ケースには係止部材及び施錠部材が設けられている。   Generally, the locking device includes a case attached to a main body portion such as a scissors and an engagement body attached to a cover portion such as a scissors as described in Patent Document 1 below. A cutout portion penetrating the one side portion is formed on one side portion of the case. On the other hand, the engaging body is provided with a locking piece that can be projected and retracted into the case through the notch. The case is provided with a locking member and a locking member in order to lock the locking piece portion inserted into the case so that it cannot escape from the case and to maintain the locked state.

係止部材は、ケース本体内に係止位置と解除位置との間を回動可能に収容されており、ケース内に設けられたばねによって解除位置から係止位置へ向かって付勢されている。係止片部が切欠き部からケース内に挿入されると、係止部材が係止片部によりばねの付勢力に抗して解除位置側へ回動させられる。係止片部が所定の位置まで挿入されると、係止部材が係止位置側へ回動可能になり、ばねの付勢力によって係止位置まで回動させられる。すると、係止部材が係止片部に係合し、係止片部がケースから脱出するのを阻止する。係止位置に位置している係止部材をばねの付勢力に抗して解除位置に回動させると、係止部材による係止片部に対する係止状態が解除され、係止片部が切欠き部を通ってケースから脱出可能になる。したがって、係合体をケースから取り外すことができる。   The locking member is accommodated in the case main body so as to be rotatable between a locking position and a releasing position, and is biased from the releasing position toward the locking position by a spring provided in the case. When the locking piece is inserted into the case from the notch, the locking member is rotated toward the release position by the locking piece against the urging force of the spring. When the locking piece portion is inserted to a predetermined position, the locking member can be rotated to the locking position side, and is rotated to the locking position by the biasing force of the spring. Then, the locking member engages with the locking piece, and the locking piece is prevented from escaping from the case. When the locking member located at the locking position is rotated to the release position against the biasing force of the spring, the locking state of the locking piece by the locking member is released and the locking piece is cut off. It becomes possible to escape from the case through the notch. Therefore, the engaging body can be removed from the case.

一方、施錠部材は、ケースに施錠位置と開錠位置との間を回動可能に設けられている。施錠部材を施錠位置に回動させると、施錠部材が係止部材を係止位置に位置固定する。これにより、係止片部が係止部材によりケースから脱出不能な状態に維持される。一方、施錠部材を開錠位置に回動させると、係止部材が係止位置から解除位置へ回動可能になる。係止部材を解除位置に回動させることにより、係止部材による係止片部に対する係止状態が解除される。   On the other hand, the locking member is provided in the case so as to be rotatable between a locking position and an unlocking position. When the locking member is rotated to the locking position, the locking member fixes the locking member at the locking position. Thereby, the locking piece is maintained in a state in which it cannot escape from the case by the locking member. On the other hand, when the locking member is rotated to the unlocking position, the locking member can be rotated from the locking position to the release position. By rotating the locking member to the release position, the locked state of the locking piece by the locking member is released.

施錠装置は、施錠部材が施錠位置に位置しているときには開錠位置に位置しているときよりも係合体がケースから離脱するのをより大きな力で阻止することができるものであることが望ましい。施錠部材が施錠位置に位置しているときには、開錠位置に位置しているときより鞄や収容ボックス等が開かれるのをより確実に防止したいからである。しかるに、上記従来の施錠装置においては、施錠部材が施錠位置と開錠位置とのいずれに位置している場合であっても、係止片部を係止するのは係止部材だけである。このため、係合体がケースから離脱するのを阻止する阻止力はいずれの場合でも一定であり、施錠部材が施錠位置に位置しているときには係合体がケースから離脱するのをより大きな力で阻止したいという要望には全く応えることができなかった。   It is desirable that the locking device can prevent the engagement body from being detached from the case with a larger force when the locking member is positioned at the locking position than when the locking member is positioned at the unlocking position. . This is because when the locking member is located at the locking position, it is desired to more reliably prevent the bag or the storage box from being opened than when the locking member is located at the unlocking position. However, in the above-described conventional locking device, only the locking member locks the locking piece portion regardless of whether the locking member is positioned at the locking position or the unlocking position. For this reason, the blocking force that prevents the engagement body from detaching from the case is constant in any case, and when the locking member is located at the locking position, the engagement body is prevented from detaching from the case with a larger force. I couldn't meet the desire to do it at all.

この発明は、上記の問題を解決するために、ケースと、このケースに対して接近離間移動可能である係合体とを備え、上記ケースには、係止部材と施錠部材とが設けられ、上記係止部材が、上記係合体に係合して上記係合体が上記ケースから離間する方向へ移動するのを阻止する係止位置と、上記係合体が上記ケースから離間する方向への移動を許容する解除位置との間を変位可能とされ、上記施錠部材が施錠位置と開錠位置との間を変位可能とされた施錠装置において、上記ケースには、上記施錠部材の変位に連動して変位し、上記施錠部材が上記施錠位置に位置しているときには阻止位置に位置し、上記施錠部材が上記開錠位置に位置しているときには許容位置に位置する第２係止部材が設けられ、この第２係止部材は、上記阻止位置に位置しているときには上記係合体に係合して上記係合体が上記ケースから離間する方向へ移動するのを阻止し、上記許容位置に位置しているときには上記係合体が上記ケースから離間する方向へ移動するのを許容し、上記第２係止部材は、上記阻止位置に位置しているときには、上記係止部材に係合して上記係止部材が上記係止位置から上記解除位置に変位するのを阻止し、上記許容位置に位置しているときには、上記係止部材から離間して上記係止部材が上記係止位置から上記解除位置に変位するのを許容することを特徴としている。
この場合、上記第２係止部材は、上記施錠部材に固定されていることが望ましい。
上記係止部材、上記施錠部材及び上記第２係止部材が上記ケースの内部に設けられ、上記ケースの一側部には、上記ケースの内部を外部に開放し、上記係止位置に位置している上記係止部材の上記係合体に係合する一端部及び上記阻止位置に位置している上記第２係止部材の上記係合体に係合する一端部が上記ケースの内部から外部に通り抜ける切欠き部が形成され、上記係合体には上記係止部材及び上記第２係止部材の上記ケースから外部に突出した各一端部がそれぞれ係脱可能に係合する係合片部が設けられていることが望ましい。
上記係止部材、上記施錠部材及び上記第２係止部材が上記ケースの内部に設けられ、上記ケースにはその内部を外部に開放する切欠き部が設けられ、上記係合体には、上記切欠き部を通って上記ケースの内部に挿入可能な係止片部が設けられ、上記係止部材及び上記第２係止部材が上記ケース内に挿入された上記係止片部に係脱可能に係合することが望ましい。
上記係止部材と上記第２係止部材とは、上記係止片部の一側部と他側部とにそれぞれ係合させることが望ましい。
上記係止部材は、上記係止位置と上記解除位置との間を回動可能とされていてもよく、上記係止位置と上記解除位置との間を直線移動可能とされていてもよい。
上記施錠部材は、上記施錠位置と上記開錠位置との間を回動可能とされていてもよく、上記施錠位置と上記開錠位置との間を直線移動可能とされていてもよい。 In order to solve the above-described problem, the present invention includes a case and an engaging body that can move toward and away from the case. The case includes a locking member and a locking member. A locking position at which the locking member engages with the engagement body and prevents the engagement body from moving in a direction away from the case; and movement of the engagement body in a direction away from the case is permitted. In the locking device in which the locking member is displaceable between the unlocking position and the locking member is displaceable between the locking position and the unlocking position , the case is displaced in conjunction with the displacement of the locking member. When the locking member is located at the locking position, a second locking member is provided, which is located at the blocking position, and when the locking member is located at the unlocked position, a second locking member is provided. The second locking member is at the blocking position. The engagement body engages with the engagement body to prevent the engagement body from moving in a direction away from the case, and the engagement body moves away from the case when positioned at the allowable position. The second locking member is engaged with the locking member and the locking member is displaced from the locking position to the release position when the second locking member is positioned at the blocking position. When it is located at the allowable position, it is separated from the locking member, and the locking member is allowed to be displaced from the locking position to the release position .
In this case, it is desirable that the second locking member is fixed to the locking member.
The locking member, the locking member, and the second locking member are provided inside the case, and one side portion of the case opens the inside of the case to the outside and is positioned at the locking position. One end portion of the locking member that engages with the engaging body and one end portion of the second locking member that is positioned at the blocking position pass from the inside of the case to the outside. A notch is formed, and the engaging body is provided with an engaging piece for removably engaging each end of the locking member and the second locking member protruding from the case. It is desirable that
The locking member, the locking member, and the second locking member are provided inside the case. The case is provided with a notch that opens the inside to the outside. A locking piece that can be inserted into the case through the notch is provided so that the locking member and the second locking member can be engaged with and disengaged from the locking piece inserted in the case. It is desirable to engage.
It is desirable that the locking member and the second locking member are respectively engaged with one side and the other side of the locking piece.
The locking member may be rotatable between the locking position and the releasing position , or may be linearly movable between the locking position and the releasing position .
The locking member may be rotatable between the locking position and the unlocking position, and may be linearly movable between the locking position and the unlocking position.

上記特徴構成を有するこの発明によれば、施錠部材が開錠位置に位置しているときには、係止部材が係止片部を係止するだけであるのに対し、施錠部材が施錠位置に位置しているときには、係止部材に加えて第２係止部材が係止片部を係止する。したがって、係合体がケースから離脱するのをより大きな力で確実に阻止することができる。   According to the present invention having the above-described characteristic configuration, when the locking member is positioned at the unlocked position, the locking member only locks the locking piece, whereas the locking member is positioned at the locking position. When doing so, the second locking member locks the locking piece in addition to the locking member. Therefore, it is possible to reliably prevent the engagement body from being detached from the case with a larger force.

以下、この発明を実施するための最良の形態を、添付の図１〜図１１を参照して説明する。
図１〜図６に示すように、この発明に係る施錠装置１は、ケース２と係合体３とを備えている。 The best mode for carrying out the present invention will be described below with reference to FIGS.
As shown in FIGS. 1 to 6, the locking device 1 according to the present invention includes a case 2 and an engagement body 3.

ケース２は、図７〜図９及び図１１に示すように、背面が開口した略直方体の箱状をなしており、その上面（以下、上下左右は、図面上での上下左右を意味するものであり、この発明はそれに限定されるものではない。）には、突出部（一側部）２ａが形成されている。この突出部２ａには、切欠き部２ｂが形成されている。この切欠き部２ｂは、突出部２ａを上下に貫通している。したがって、ケース２の内部は、切欠き部２ｂを介して外部に開放されている。切欠き部２ｂは、ケース２の背面側にも開放されている。しかし、切欠き部２ｂは、必ずしもケース２の背面側に開放する必要はない。その場合には、切欠き部２ｂは貫通孔の形状を呈することになる。ケース２の前面の中央部には、当該中央部を貫通する装着孔２ｃが形成されている。ケース２の前面と下面との交差部には、当該交差部を貫通する操作窓孔２ｄが形成されている。ケース２の背面部には、裏蓋４がビス５によって固定されている。この裏蓋４により、切欠き部２ｂを除くケース２の背面開口部が塞がれている。なお、裏蓋４が取り付けられたケース２は、その背面及び裏蓋を鞄等の本体（図示せず）の前面に押し付けた状態で当該本体に取り付けられる。   As shown in FIGS. 7 to 9 and 11, the case 2 has a substantially rectangular parallelepiped box shape with an open back surface, and its upper surface (hereinafter, “upper, lower, left, and right” means upper, lower, left, and right in the drawing). The present invention is not limited to this, and a protruding portion (one side portion) 2a is formed. A cutout portion 2b is formed in the protruding portion 2a. This notch part 2b has penetrated the protrusion part 2a up and down. Therefore, the inside of the case 2 is opened to the outside through the notch 2b. The notch 2 b is also opened on the back side of the case 2. However, the notch 2b is not necessarily opened to the back side of the case 2. In that case, the notch 2b has the shape of a through hole. A mounting hole 2c penetrating the central portion is formed in the central portion of the front surface of the case 2. An operation window hole 2d penetrating the intersection is formed at the intersection between the front surface and the lower surface of the case 2. A back cover 4 is fixed to the back surface of the case 2 with screws 5. The back cover 4 closes the back opening of the case 2 except for the notch 2b. In addition, the case 2 to which the back cover 4 is attached is attached to the main body in a state where the back face and the back cover are pressed against the front face of a main body (not shown) such as a bag.

係合体３は、図７、図８、図１０及び図１１に示すように、本体部３ａを有している。本体部３ａは、その下面がケース２の上面に突き当たったとき（以下、このときの係合体３のケース２に対する位置をロック位置という。）、本体部３ａの内部の下部に突出部２ａが嵌合し、本体部３ａの下部内面が突出部２ａの前面及び左右両側面に接触するようになっている。これにより、係合体３のケース２に対する後方及び左右方向への移動が規制されている。しかも、係合体３は、鞄等のカバー部（図示せず）の前面に取り付けられるので、施錠装置１の施錠時に鞄等のカバー部が本体の前面に突き当たると、それによってもケース２に対する後方への移動が規制される。 The engaging body 3 has a main body 3a as shown in FIGS. When the lower surface of the main body 3a hits the upper surface of the case 2 (hereinafter, the position of the engaging body 3 with respect to the case 2 is referred to as a lock position), the projecting portion 2a is fitted into the lower portion inside the main body 3a. The lower inner surface of the main body portion 3a is in contact with the front surface and the left and right side surfaces of the protruding portion 2a. Thereby, the movement to the back and the left-right direction with respect to the case 2 of the engaging body 3 is controlled. Moreover, since the engaging body 3 is attached to the front surface of a cover portion (not shown) such as a bag , if the cover portion such as the bag hits the front surface of the main body when the locking device 1 is locked, the engagement body 3 is also against the case 2. Backward movement is restricted .

本体部３ａの略中央部には、係止片部３ｂが設けられている。この係止片部３ｂの下端部は、本体部３ａの下面から下方へ突出しており、係合体３をロック位置に位置させると、切欠き部２ｂを通ってケース２の内部に入り込む。そして、係止片部３ｂがケース２内に入り込むと、ケース２内に設けられた係止部材１０又は係止部材１０及び係合部材２３が係止片部３ｂに係合する。これにより、係合体３がロック位置においてケース２に離脱不能に係止されるようになっている。係止部材１０又は係止部材１０及び係合部材２３の係止片部３ｂに対する係合を解除すると、本体部３ａに上下方向へ所定範囲移動可能に設けられた可動部材６及びこの可動部材６を下方へ付勢する付勢手段としてのコイルばね７、並びケース２に設けられた後述するコイルばね１２により、係合体３がロック位置から図１１（Ａ）に示すアンロック位置まで移動させられる。 A locking piece 3b is provided at a substantially central portion of the main body 3a. The lower end portion of the locking piece portion 3b protrudes downward from the lower surface of the main body portion 3a, and enters the inside of the case 2 through the notch portion 2b when the engaging body 3 is positioned at the lock position. Then, the locking piece portion 3b when entering into the case 2, the engaging member 10 or engagement member 10 and the engagement member 23 provided in the case 2 is engaged with the locking piece portion 3b. As a result, the engagement body 3 is locked to the case 2 so as not to be detached at the lock position. When the engagement of the locking member 10 or the locking member 10 and the engaging member 23 with respect to the locking piece 3b is released, the movable member 6 provided in the main body 3a so as to be movable within a predetermined range in the vertical direction, and the movable member 6 The engagement body 3 is moved from the locked position to the unlocked position shown in FIG. 11 (A) by the coil spring 7 as a biasing means for biasing the spring downward and the coil spring 12 described later provided in the case 2. .

係合体３のケース２への係止は、次のようにして行われる。すなわち、図１１に示すように、係止片部３ｂの本体部３ａから下方へ突出した下端部の前面には、前方へ向かって突出する係合突起３ｃが形成されている。一方、ケース２の内部には、板状をなす係止部材１０が設けられている。この係止部材１０は、左右方向へ水平に延びる一対の軸部１０ａ，１０ａを有しており、この一対の軸部１０ａ，１０ａを介してケース２に回動可能に支持されている。係止部材１０の回動範囲は、図１１（Ｂ）に示す係止位置と、図１１（Ｃ）に示す解除位置との間に制限されている。係止部材１０が係止位置に位置すると、係止部材１０の上端部に形成されたフック部１０ｂが係止片部３ｂの係合突起３ｃの上面に接触する。これにより、係止片部３ｂの上方への移動が阻止され、係合体３がロック位置においてケース２に位置固定される。係止部材１０を解除位置に回動させると、フック部１０ｂが係合突起３ｃから前方へ離間する。この結果、係止片部３ｂが上方へ移動可能になり、係合体３がケース２に対しロック位置から上方へ移動可能になる。   The engagement body 3 is locked to the case 2 as follows. That is, as shown in FIG. 11, an engaging projection 3c that protrudes forward is formed on the front surface of the lower end portion that protrudes downward from the main body 3a of the locking piece 3b. On the other hand, a locking member 10 having a plate shape is provided inside the case 2. The locking member 10 has a pair of shaft portions 10a and 10a extending horizontally in the left-right direction, and is rotatably supported by the case 2 via the pair of shaft portions 10a and 10a. The rotation range of the locking member 10 is limited between the locking position shown in FIG. 11 (B) and the release position shown in FIG. 11 (C). When the locking member 10 is positioned at the locking position, the hook portion 10b formed on the upper end portion of the locking member 10 comes into contact with the upper surface of the engagement protrusion 3c of the locking piece portion 3b. Thereby, the upward movement of the locking piece 3b is prevented, and the engaging body 3 is fixed to the case 2 in the locked position. When the locking member 10 is rotated to the release position, the hook portion 10b is separated forward from the engagement protrusion 3c. As a result, the locking piece 3b can move upward, and the engagement body 3 can move upward from the lock position with respect to the case 2.

係止部材１０の下端部には、操作部材１１が固定されている。この操作部材１１は、係止部材１０と一体に形成してもよい。操作部材１１は、ケース２の操作窓孔２ｄと対向するように配置されており、付勢手段たるコイルばね１２に操作窓孔２ｄに向かって付勢されている。操作部材１１は、ケース２の前壁部の内面に突き当たると、それ以上前方へ移動（実際には、軸１０ａを中心として回動）することができなくなっている。その結果、操作部材１１に固定された係止部材１０が、それ以上図１１（Ｂ）の時計方向へ回動することができなくなっている。このときの係止部材１０の位置が係止位置である。その一方、操作部材１１をコイルばね１２の付勢力に抗してケース２の後方側へ移動させた場合には、操作部材１１の後方への移動に伴って係止部材１０が反時計方向へ回動し、その上端部がケース２の前壁部の内面に突き当たると、係止部材１０がそれ以上反時計方向へ回動することができなくなり、ひいては操作部材１１がそれ以上後方へ移動することができなくなる。このときの係止部材１０の位置が解除位置である。   An operation member 11 is fixed to the lower end portion of the locking member 10. The operation member 11 may be formed integrally with the locking member 10. The operation member 11 is disposed so as to face the operation window hole 2d of the case 2, and is urged toward the operation window hole 2d by a coil spring 12 as an urging means. When the operation member 11 hits the inner surface of the front wall portion of the case 2, it can no longer move forward (actually, it rotates about the shaft 10 a). As a result, the locking member 10 fixed to the operation member 11 can no longer be rotated in the clockwise direction in FIG. The position of the locking member 10 at this time is the locking position. On the other hand, when the operation member 11 is moved to the rear side of the case 2 against the urging force of the coil spring 12, the locking member 10 moves counterclockwise as the operation member 11 moves rearward. When the upper end portion of the case 2 comes into contact with the inner surface of the front wall portion of the case 2, the locking member 10 can no longer turn counterclockwise, and the operation member 11 moves further rearward. I can't do that. The position of the locking member 10 at this time is the release position.

ケース２の装着孔２ｃには、錠前機構２０が設けられている。錠前機構２０は、装着孔２ｃに軸線を前後方向に向けて嵌合固定された筒体２１と、この筒体２１に回動可能に嵌合された回動部材２２とを有している。回動部材２２は、その前面に開口するキー孔２２ａを有しており、このキー孔２２ａにキー（図示せず）を挿入することにより、回動部材２２を筒体２１に対して回動させることができる。回動部材２２の回動範囲は、キー孔２２ａの長手方向が上下方向を向いた開錠位置（図１１（Ａ）、（Ｃ）に示す位置）と、開錠位置から図１の時計方向へ９０°離れた（その結果、キー孔２２の長手方向が左右方向を向いた）施錠位置（図１１（Ｂ）に示す位置）との間に規制されている。 A lock mechanism 20 is provided in the mounting hole 2 c of the case 2. The lock mechanism 20 includes a cylindrical body 21 that is fitted and fixed in the mounting hole 2c with its axis directed in the front-rear direction, and a rotating member 22 that is rotatably fitted to the cylindrical body 21. The rotating member 22 has a key hole 22a that opens on the front surface thereof. By inserting a key (not shown) into the key hole 22a, the rotating member 22 is rotated with respect to the cylindrical body 21. Can be made. The pivoting range of the pivoting member 22 is the unlocked position (position shown in FIGS. 11A and 11C) in which the longitudinal direction of the key hole 22a is directed in the vertical direction, and the clockwise direction of FIG. 1 from the unlocked position. To the locking position (the position shown in FIG. 11B) that is 90 degrees away from the center (as a result, the longitudinal direction of the key hole 22 faces the left-right direction).

回動部材２２の内側の端部には、板状をなす係合部材（第２係止部材）２３の中央部が固定されている。この係合部材２３は、係止部材１０を係止位置に位置させた状態において回動部材２２を施錠位置に回動させると、図１１（Ｂ）に示すように、係合部材２３の下端部が係止部材１０に突き当たり、それによって係止部材１０が係止位置から解除位置側へ回動するのを阻止する。この結果、係合体３がケース２に対してロック位置に位置固定される。回動部材２２を施錠位置から開錠位置まで回動させると、係合部材２３の一端部が係止部材１０から上方へ離間する。この結果、係止部材１０が係止位置から解除位置まで回動可能になる。これから明らかなように、この施錠装置１では、回動部材２２と係合部材２３とによって施錠部材２４が構成されている。回動部材２２を開錠位置に回動させて係止部材１０を係止位置から解除位置側へ回動可能にした状態では、図１１（Ｃ）に示すように、操作部材１１をコイルばね１２の付勢力に抗して後方へ押すことにより、係止部材１０を係止位置から解除位置まで回動させることができる。係止部材１０を解除位置に回動させると、係止部材１０の係止片部３ｂに対する係止状態が解除されるので、係合体３がロック位置から上方へ移動可能になる。すると、コイルばね７の付勢力により、係合体３が上方へ移動させられる。 A central portion of a plate-like engagement member (second locking member) 23 is fixed to the inner end of the rotation member 22. The engaging member 23 rotates the pivot member 22 to the locked position in a state in which positions the locking member 10 in the locked position, as shown in FIG. 11 (B), the lower end of the engaging member 23 The portion abuts against the locking member 10, thereby preventing the locking member 10 from rotating from the locking position to the release position. As a result, the engaging body 3 is fixed to the lock position with respect to the case 2. When the rotating member 22 is rotated from the locked position to the unlocked position, one end of the engaging member 23 is separated upward from the locking member 10. As a result, the locking member 10 can rotate from the locking position to the release position. As is clear from this, in this locking device 1, the locking member 24 is constituted by the rotating member 22 and the engaging member 23. In a state in which the rotation member 22 is rotated to the unlocked position and the locking member 10 can be rotated from the locking position to the release position side, as shown in FIG. By pushing backward against the urging force of 12, the locking member 10 can be rotated from the locking position to the release position. When the locking member 10 is rotated to the release position, the locked state of the locking member 10 with respect to the locking piece portion 3b is released, so that the engagement body 3 can move upward from the lock position. Then, the engagement body 3 is moved upward by the biasing force of the coil spring 7.

なお、係合体３は、コイルばね７により、アンロック位置の若干手前の位置まで上方へ移動させられる。しかも、係止部材１０がコイルばね１２によって解除位置から係止位置側へ回動させられると、係止位置の若干手前の位置においてフック部１０ｂが係止片部３ｂの係合突起３ｃの下側に形成された傾斜面３ｄに突き当たり、係止面３ｄを介して係合体３を上方へ押す。したがって、係止部材１０が係止位置までさらに回動すると、それに伴って係合体３が上方へ移動させられる。そして、係止部材１０が係止位置に達すると、図１１（Ａ）に示すように、係合体３がアンロック位置まで上方へ移動させられる。つまり、係合体３は、付勢手段７，１２により、ロック位置からアンロック位置まで連続して移動させられる。 The engagement body 3 is moved upward by the coil spring 7 to a position slightly before the unlock position. In addition, when the locking member 10 is rotated from the release position to the locking position side by the coil spring 12, the hook portion 10b is below the engagement protrusion 3c of the locking piece portion 3b at a position slightly before the locking position. It strikes against the inclined surface 3d formed on the side and pushes the engagement body 3 upward via the locking surface 3d. Therefore, when the locking member 10 further rotates to the locking position, the engagement body 3 is moved upward accordingly. When the locking member 10 reaches the locking position, the engagement body 3 is moved upward to the unlocking position as shown in FIG. That is, the engaging body 3 is continuously moved from the locked position to the unlocked position by the biasing means 7 and 12.

係合体３が係止部材１０によってロック位置に係止された状態において、回動部材２２を施錠位置に回動させると、係合部材２３の上端部が係合体３の係止片部３ｂの下端部に係合するようになっている。すなわち、係止片部３ｂの下端部の背面（係合突起３ｃが形成された面と逆側を向く面）には、係合溝３ｅが形成されている。この係合溝３ｅは、上下方向においては係合突起３ｃとほぼ同一位置に配置されている。これは、係合溝３ｅが形成されることによって係止片部３ｂの強度が低下するのを極力防止するためである。係合溝３ｅは、係止片部３ｂの左右方向の一側面から回動部材２２の軸線の真上の位置より若干他側面側の位置まで延びている。しかも、係合溝３ｅは、回動部材２２の軸線から所定距離だけ真下に離れた点を中心とする円弧に沿って形成されている。係合溝３ｅは、係止片部３ｂの他側面まで形成してもよいが、この実施の形態のように他側面の手前の位置で止めるのがよい。そのようにすれば、係合溝３ｅを形成したことによる係止片部３ｂの強度低下を極力防止することができるからである。 In a state where the engaging body 3 is locked at the locking position by the locking member 10, when the rotating member 22 is rotated to the locking position, the upper end portion of the engaging member 23 is the locking piece portion 3 b of the engaging body 3. It engages with the lower end. That is, the engagement groove 3e is formed on the back surface (the surface facing the surface opposite to the surface on which the engagement protrusion 3c is formed) of the lower end portion of the locking piece portion 3b. The engagement groove 3e is disposed at substantially the same position as the engagement protrusion 3c in the vertical direction. This is to prevent the strength of the locking piece portion 3b from being reduced as much as possible by forming the engaging groove 3e. The engaging groove 3e extends from one side surface in the left-right direction of the locking piece 3b to a position on the other side surface slightly from a position directly above the axis of the rotating member 22. In addition, the engagement groove 3e is formed along an arc centered at a point that is a predetermined distance away from the axis of the rotating member 22. Although the engagement groove 3e may be formed up to the other side surface of the locking piece portion 3b, it may be stopped at a position in front of the other side surface as in this embodiment. By so doing, it is possible to prevent as much as possible the reduction in strength of the locking piece 3b due to the formation of the engaging groove 3e.

係合部材２３の上端部には、前方へ向かって突出する係合突出部２３ａが形成されている。この係合突出部２３ａの厚さは、係合溝３ｅの溝幅より薄くなっている。係合突出部２３ａは、係止部材１０が係止位置に位置して係止片部３ｂに係合した状態において、回動部材２２を開錠位置から施錠位置の若干手前の位置まで回動させると、係合溝３ｅにその一端開放部から入り込む。係合突出部２３ａは、回動部材２２を施錠位置まで回動させると、係合溝３ｅのうちの、回動部材２２の真上に位置する上端部まで入り込む。係合突出部２３ａは、係合溝３ｅの一端開口部においては係合溝３ｅの幅方向の中央部に位置しているが、係合溝３ｅの上端部まで入り込むと、係合溝３ｅの下側の側面に接触する。したがって、回動部材２２を施錠位置に回動させると、係止片部３ｂが係合部材２３によって上方へ移動不能に係止される。これから明らかなように、この実施の形態の施錠装置１においては、係止部材１０を係止位置に維持するための係合部材２３が、係止片部３ｂに係合してその上方への移動を阻止する第２係止部材として兼用されている。したがって、回動部材２２が施錠位置に位置し、それに伴って係合部材２３が係合溝３ｅの下側の側面に接触したときの係合部材２３の位置が阻止位置であり、回動部材２２が開錠位置に位置し、それに伴って係合部材２３が９０°回動して係合溝３ｅから脱出したときの係合部材２３の位置が許容位置である。 At the upper end of the engagement member 23, an engagement protrusion 23a that protrudes forward is formed. The thickness of the engaging protrusion 23a is smaller than the groove width of the engaging groove 3e. The engaging protrusion 23a rotates the rotating member 22 from the unlocking position to a position slightly before the locking position in a state where the locking member 10 is positioned at the locking position and engaged with the locking piece 3b. If it does, it will enter into the engaging groove 3e from the one end open part. When the rotation member 22 is rotated to the locking position, the engagement protrusion 23a enters the upper end portion of the engagement groove 3e that is positioned directly above the rotation member 22. The engagement protrusion 23a is positioned at the center of the engagement groove 3e in the width direction at the one end opening of the engagement groove 3e. However, when the engagement protrusion 23a enters the upper end of the engagement groove 3e, Touch the lower side. Therefore, when the rotating member 22 is rotated to the locking position, the locking piece 3b is locked by the engaging member 23 so as not to move upward. As is clear from this, in the locking device 1 of this embodiment, the engaging member 23 for maintaining the locking member 10 in the locking position engages with the locking piece 3b and moves upward. It is also used as a second locking member that prevents movement. Therefore, rotation member 22 is positioned in the locking position, the position is a blocking position of engagement member 23 when engagement member 23 is in contact with the lower side of the engagement groove 3e concomitantly, the rotating member The position of the engaging member 23 when the engaging member 23 is rotated by 90 ° and escapes from the engaging groove 3e is positioned at the unlocking position.

上記構成の施錠装置１において、係合体３をケース２に係止する場合には、回動部材２２を開錠位置に位置させておき、係止部材１０を係止位置に位置させておく。その状態で、係合体３の係止片部３ｂを切欠き部２ｂを通してケース２内に挿入すると、傾斜面３ｄがフック部１０ｂに突き当たり、係止部材１０をコイルばね１２の付勢力に抗して係止位置から解除位置側へ回動させる。係合体３をロック位置まで移動させると、係合突起３ｃがフック部１０ｂを乗り越える結果、係止部材１０が解除位置側から係止位置側へ回動可能になる。係止部材１０がコイルばね１２によって係止位置まで回動させられると、フック部１０ｂと係合突起３ｃとが係合する。これによって、係合体３がロック位置においてケース２に上方へ移動不能に係止される。しかも、係合体３の本体部３ａの下端面がケース２の上面に突き当たるとともに、本体部３ａの下端部内面が突出部２ａの前面及び左右両側面に突き当たっているので、係合体３はケース２にほとんど移動不能に固定される。 In the locking device 1 configured as described above, when the engaging body 3 is locked to the case 2, the rotating member 22 is positioned at the unlocked position, and the locking member 10 is positioned at the locked position . In this state, when the locking piece 3b of the engaging body 3 is inserted into the case 2 through the notch 2b, the inclined surface 3d hits the hook 10b, and the locking member 10 is resisted against the biasing force of the coil spring 12. To rotate from the locking position to the release position. When the engagement body 3 is moved to the lock position, the engagement protrusion 3c gets over the hook portion 10b, so that the engagement member 10 can be rotated from the release position side to the engagement position side. When the locking member 10 is rotated to the locking position by the coil spring 12, the hook portion 10b and the engagement protrusion 3c are engaged. As a result, the engaging body 3 is locked to the case 2 so as not to move upward in the locked position. Moreover, since the lower end surface of the main body portion 3a of the engaging body 3 abuts against the upper surface of the case 2, the inner surface of the lower end portion of the main body portion 3a abuts against the front surface and the left and right side surfaces of the projecting portion 2a. Fixed to almost immovable.

次に、キー孔２２ａにキーを差し込んで回動部材２２を開錠位置から施錠位置まで回動させる。すると、係合部材２３が係止部材１０に係合して係止部材１０の係止位置から解除位置側への回動を阻止する。したがって、操作部材１１を誤って押したとしても係合体３がケース２から離脱することがない。また、回動部材２２を施錠位置に回動させると、係合部材２３の係合突出部２３ａが係合溝３ｅに入り込む。これにより、係合部材２３が係止片部３ｂを上方へ移動不能に係止する。したがって、係合体３は、係止部材１０に加え、係合部材２３によっても上方への移動が阻止される。よって、係合体３は、ケース２に確実に係止される。しかも、係止部材１０と係合部材２３とは、係止片部３ｂに対して前面側部分と背面側部分とにおいてそれぞれ係合しているので、同一面側で係合する場合に比して係止片部３ｂをバランスよく係止することができる。   Next, a key is inserted into the key hole 22a to rotate the rotating member 22 from the unlocked position to the locked position. Then, the engaging member 23 engages with the locking member 10 to prevent the locking member 10 from rotating from the locking position to the release position side. Therefore, even if the operating member 11 is pushed by mistake, the engaging body 3 does not leave the case 2. Further, when the rotation member 22 is rotated to the locking position, the engagement protrusion 23a of the engagement member 23 enters the engagement groove 3e. Thereby, the engaging member 23 locks the locking piece 3b so as not to move upward. Therefore, the engagement body 3 is prevented from moving upward by the engagement member 23 in addition to the locking member 10. Therefore, the engagement body 3 is securely locked to the case 2. Moreover, since the locking member 10 and the engaging member 23 are engaged with the locking piece portion 3b in the front side portion and the back side portion, respectively, compared with the case of engaging on the same surface side. Thus, the locking piece 3b can be locked with a good balance.

ロック位置に係止された係合体３をケース２から取り外す場合には、キー孔２２ａにキーを差し込んで回動部材２２を施錠位置から開錠位置まで回動させる。すると、係合部材２３の係止部材１０及び係止片部３ｂに対する各係合が解除される。その後、操作部材１１をケース２の内部側に押し、係止部材１０を係止位置から解除位置まで回動させる。これにより、係止部材１０の係止片部３ｂに対する係止状態を解除する。すると、係合体３がコイルばね７によってロック位置から上方へ移動させられ、引き続きコイルばね１２によってアンロック位置まで移動させられる。したがって、操作部材１１から手を離し、係止部材１０をコイルばね１２によって係止位置まで回動させたとしても、係止部材１０が係止片部３ｂに再び係合することはない。その後、係合体３を上方へ移動させることにより、ケース２から取り外すことができる。   When the engagement body 3 locked at the lock position is removed from the case 2, a key is inserted into the key hole 22a to rotate the rotation member 22 from the lock position to the unlock position. Then, each engagement with the locking member 10 and the locking piece 3b of the engaging member 23 is released. Thereafter, the operating member 11 is pushed toward the inside of the case 2 to rotate the locking member 10 from the locking position to the release position. Thereby, the latching state with respect to the latching piece part 3b of the latching member 10 is cancelled | released. Then, the engaging body 3 is moved upward from the locked position by the coil spring 7 and is subsequently moved to the unlocked position by the coil spring 12. Therefore, even if the hand is released from the operation member 11 and the locking member 10 is rotated to the locking position by the coil spring 12, the locking member 10 is not re-engaged with the locking piece 3b. Thereafter, the engagement body 3 can be removed from the case 2 by moving it upward.

例えば、上記実施の形態においては、係止位置と解除位置との間を回動する係止部材１０が用いられているが、係止位置と解除位置との間を直線移動する係止部材を用いてもよい。
また、上記実施の形態においては、キーで回動部材２２を回動させるタイプの錠前機構２０が用いられているが、開錠位置と施錠位置との間を直線移動可能な施錠部材を有するプッシュタイプの錠前機構を用いてもよい。その場合には、ケース２の前面から突出した施錠部材の一端部をケース２の内側に向かって押して、施錠部材を開錠位置から施錠位置まで押し込んだときに、施錠部材が係止片部３ｂに係合するように構成すればよい。プッシュタイプの錠前機構は、直線移動する係止部材と組み合わせてもよい。
また、上記実施の形態においては、施錠部材２４の一部を構成する係合部材２３を第２係止部材として兼用しているが、係合部材２３とは別部材である第２係止部材を回動部材２２に設けてもよい。
さらに、上記の実施の形態においては、係合体３にケース２の内部に挿入される係止片部３ｂを設け、この係止片部３ｂに係止部材１０及び第２係止部材たる係合部材２３を係合させているが、係止部材１０及び係合部材２３の各一部をケース２から外部に突出させ、その突出した一部を係合体３に係脱可能に係合させてもよい。 The present invention is not limited to the above-described embodiment, and can be changed as appropriate without departing from the scope of the invention.
