Description

ロック機構およびロック機構を備えた装置Locking mechanism and device with locking mechanism
　本発明は、ロック機構およびロック機構を備えた装置に関する。 The present invention relates to a locking mechanism and an apparatus provided with the locking mechanism.
　現金自動預払い機等の自動取引装置（ＡＴＭ：Automated /Automatic Teller Machine）には様々なロック機構が使用されており、実開平５－０４９７５５号公報には収納庫を装置本体に固定するロック機構が記載されている。 Various lock mechanisms are used in automatic transaction devices (ATM: Automated / Automatic Teller Machine) such as cash dispensers, and in Japanese Utility Model Application Publication No. 5-049755, the lock mechanism is used to fix the storage to the main body of the apparatus. Is described.
　また、従来の自動取引装置は、入出金ユニット等の機構ユニットや金庫部などを隠すために前扉が実装されており、この前扉にもロック機構が使用される。 Further, in the conventional automatic transaction apparatus, a front door is mounted to hide a mechanism unit such as a deposit and withdrawal unit and a safe unit, and a lock mechanism is also used for the front door.
　従来の自動取引装置は、操作者によって叩かれた場合に、叩かれた衝撃が前扉のロック機構に伝わり、ロックが解除して前扉が開放してしまうという問題があった。自動取引装置が叩かれる場合とは、例えば、自動取引装置による処理が何らかの理由によって滞った場合（例えば故障した場合）や盗難を目的とした場合である。 The conventional automated teller machine has a problem that when it is hit by the operator, the hit impact is transmitted to the lock mechanism of the front door, and the lock is released to open the front door. The automatic transaction apparatus is beaten, for example, when the processing by the automatic transaction apparatus is delayed for some reason (for example, when it breaks down) or when it is intended for theft.
前扉のロック機構は、前扉や装置本体の筺体の近くに実装されるので、叩かれる位置から衝撃が伝わり易いため特に問題になる。前扉が開くと装置本体に収納される機構ユニットや金庫部が露出するので、防犯の観点から好ましくない。 Since the lock mechanism of the front door is mounted near the front door and the case body of the device body, it is particularly problematic because an impact can be easily transmitted from the hit position. When the front door is opened, the mechanical unit and the safe unit stored in the apparatus body are exposed, which is not preferable from the viewpoint of crime prevention.
　本発明は、前記問題に鑑みてなされたものであり、外部からの衝撃による解除を防ぐことができる、ロック機構およびロック機構を備えた装置を提供するものである。 The present invention has been made in view of the above problems, and provides an apparatus provided with a lock mechanism and a lock mechanism capable of preventing release due to external impact.
　前記課題を解決するため、本発明の一態様に係るロック機構は、扉の開放を規制するロック機構であって、前記扉とは別部材に形成されているリミッタと、前記扉に回動可能に取り付けられており、前記リミッタに当接することで前記扉の開放を規制する開放規制位置及び前記リミッタとの当接を回避することで前記扉の開放を許容する開放許容位置に移動するロックレバと、を備え、前記ロックレバは、前記リミッタとの当接領域に前記開放許容位置への移動を規制する回動規制部を有することを特徴とする。 In order to solve the above-mentioned subject, the lock mechanism concerning one mode of the present invention is a lock mechanism which regulates the opening of a door, and it is pivotable to the limiter formed in the member different from the door, and the door And a lock lever moving to an open permitting position permitting opening of the door by avoiding contact with the open restricting position for restricting the opening of the door by abutting on the limiter and avoiding the contact with the limiter. The lock lever has a rotation restricting portion for restricting the movement to the open allowable position in the contact area with the limiter.
　また、本発明の一態様に係る装置は、前記ロック機構を備えた装置である。 An apparatus according to an aspect of the present invention is an apparatus provided with the lock mechanism.
　本発明によれば、外部からの衝撃による解除を防ぐことができる。 According to the present invention, release due to external impact can be prevented.

The front door 1 is mounted on the device body 6 using a hinge not shown, and can be pivoted about a rotation center axis C. That is, the front door 1 here is a side opening door which opens the left side. The front door 1 covers the deposit / withdrawal unit 8 and the safe 9 in a closed state (the state shown in FIG. 1). The front door 1 is provided with a lock mechanism 10, and the front door 1 is prevented from opening by locking in a state where the front door 1 is closed. In addition, the structure of the front door 1 is not limited to what was demonstrated here, What is necessary is just to be able to turn to the apparatus main body 6. FIG.
≪第一実施形態に係るロック機構の構成≫
　図２を参照して、ロック機構１０の構成について説明する。図２は、第一実施形態に係るロック機構１０を説明するための図であり、図１の自動取引装置１００のＡ－Ａ断面を示す模式図である。ロック機構１０は、ロックレバ２と、リミッタ３と、付勢部材４と、ロックレバ回動軸５と、を主に備える。 << Configuration of Locking Mechanism According to First Embodiment >>
The configuration of the lock mechanism 10 will be described with reference to FIG. FIG. 2 is a view for explaining the lock mechanism 10 according to the first embodiment, and is a schematic view showing an AA cross section of the automatic transaction apparatus 100 of FIG. The lock mechanism 10 mainly includes a lock lever 2, a limiter 3, a biasing member 4, and a lock lever pivot shaft 5.
　ロックレバ回動軸５は、ロックレバ２を回動させる際の回転支点となる部材であり、前扉１の左側内部であって上下方向に配置されている。ロックレバ回動軸５は、少なくともその一部が前扉１に固定されており、前扉１の開閉動作に伴って前扉１とともに移動する。ここでのロックレバ回動軸５は、前扉１の回転中心軸Ｃ（図１参照）と平行に配設されている。 The lock lever rotation shaft 5 is a member serving as a rotation fulcrum when the lock lever 2 is rotated, and is disposed inside the left side of the front door 1 and in the vertical direction. At least a portion of the lock lever pivot shaft 5 is fixed to the front door 1 and moves together with the front door 1 as the front door 1 opens and closes. The lock lever rotation shaft 5 here is disposed in parallel with the rotation center axis C (see FIG. 1) of the front door 1.
　付勢部材４は、ロックレバ２に対して、リミッタ３へ近接する方向（図２のα１方向）に付勢力を常に付与するばねである。付勢部材４として用いるばねは、特段限定されるものではない。本実施形態の付勢部材４は、捩りコイルばねである。
　付勢部材４のコイル部４１には、ロックレバ回動軸５が挿通される。付勢部材４の一端４２は、前扉１の適所に係止される。付勢部材４の他端４３は、ロックレバ２の一部に当接するように設置され、リミッタ３へ近接する方向（図２のα１方向）に付勢力を発生する。 The biasing member 4 is a spring that always applies a biasing force to the lock lever 2 in a direction (direction α1 in FIG. 2) close to the limiter 3. The spring used as the biasing member 4 is not particularly limited. The biasing member 4 of the present embodiment is a torsion coil spring.
The lock lever rotation shaft 5 is inserted into the coil portion 41 of the biasing member 4. One end 42 of the biasing member 4 is locked in place on the front door 1. The other end 43 of the biasing member 4 is installed to abut on a part of the lock lever 2 and generates a biasing force in a direction approaching the limiter 3 (direction α1 in FIG. 2).
　リミッタ３は、意図しない前扉１の開放を規制する装置本体６側の部材である。リミッタ３は、施錠されている状態で前扉１を開放しないようにするものであればよく、その形状や材質などは特段限定されるものではない。ここでのリミッタ３は、金属製の板状部材であり、装置本体６の左壁から内側に折り曲げて形成されている。リミッタ３は、第一屈曲部３１と、第二屈曲部３２と、を主に有している。なお、リミッタ３は、装置本体６とは別部材として製造され、ボルトなどの締結部材によって装置本体６に固定されてもよい。 The limiter 3 is a member on the side of the apparatus main body 6 that regulates the opening of the unintended front door 1. The limiter 3 is only required to prevent the front door 1 from being opened in the locked state, and the shape, the material, and the like are not particularly limited. The limiter 3 here is a plate-like member made of metal and is formed by being bent inward from the left wall of the apparatus main body 6. The limiter 3 mainly has a first bending portion 31 and a second bending portion 32. The limiter 3 may be manufactured as a separate member from the device body 6 and may be fixed to the device body 6 by a fastening member such as a bolt.
　第一屈曲部３１は、装置本体６から連続して形成される部分であり、装置本体６の左壁から内側に延設している。第一屈曲部３１は、装置本体６の左壁に直交している。第二屈曲部３２は、第一屈曲部３１から連続して形成される部分であり、第一屈曲部３１の一端から後方に延設している。第二屈曲部３２は、装置本体６の左壁に平行である。言い換えると、ここでの第二屈曲部３２は、前扉１の開閉方向（ここでは前後方向）に延設している。第二屈曲部３２の後端３２ａは、ロックレバ２に当接する。 The first bending portion 31 is a portion continuously formed from the device body 6 and extends inward from the left wall of the device body 6. The first bending portion 31 is orthogonal to the left wall of the device body 6. The second bending portion 32 is a portion continuously formed from the first bending portion 31 and extends rearward from one end of the first bending portion 31. The second bent portion 32 is parallel to the left wall of the device body 6. In other words, the second bent portion 32 here extends in the opening / closing direction of the front door 1 (here, in the front-rear direction). The rear end 32 a of the second bending portion 32 abuts on the lock lever 2.
　ロックレバ２は、意図しない前扉１の開放を規制する前扉１側の部材であり、ロックレバ回動軸５を中心として回動可能である。ロックレバ２は、図示しない鍵機構の施錠動作に連動しており、施錠することによりロックレバ２はα１方向に回動し、開錠することによりロックレバ２はα２方向に回動する。つまり、ロックレバ２は、図２の実線で示す施錠された状態での位置から開錠されることで、図２の仮想線（二点鎖線）で示す位置まで移動する。施錠された状態（図２の実線で示す位置）のロックレバ２は、前扉１の開放動作を規制し、一方、開錠された状態（図２の仮想線で示す位置）のロックレバ２は、前扉１の開放動作を許容する。以下では、施錠されている状態におけるロックレバ２の位置（図２の実線で示す位置）を「開放規制位置」と呼び、開錠されている状態におけるロックレバ２の位置（図２の仮想線で示す位置）を「開放許容位置」と呼ぶ場合がある。 The lock lever 2 is a member on the front door 1 side that regulates unintended opening of the front door 1 and is rotatable around a lock lever rotation shaft 5. The lock lever 2 is interlocked with the locking operation of a key mechanism (not shown), and the lock lever 2 pivots in the α1 direction by locking and the lock lever 2 pivots in the α2 direction by unlocking. That is, the lock lever 2 is moved from the position in the locked state shown by the solid line in FIG. 2 to the position shown by the phantom line (two-dot chain line) in FIG. The lock lever 2 in the locked state (the position shown by the solid line in FIG. 2) regulates the opening operation of the front door 1, while the lock lever 2 in the unlocked state (the position shown by the phantom line in FIG. 2) is Allow the opening operation of the front door 1. Hereinafter, the position of the lock lever 2 in the locked state (the position shown by the solid line in FIG. 2) is referred to as the “release restricted position”, and the position of the lock lever 2 in the unlocked state (shown by the phantom line in FIG. Position) may be referred to as "open permitted position".
　ロックレバ２は、前扉１が施錠されている状態（図２の実線で示す開放規制位置）で前扉１を開放しないようにするものであればよく、その形状や材質などは特段限定されるものではない。ここでのロックレバ２は、金属製であり、先端が左方向（装置本体６の左壁に近接する方向）に突出した鉤状を呈している。具体的には、ここでのロックレバ２は、基端部２１と、先端部２２と、基端部２１と先端部２２とを連結する連結部２３と、を主に有している。 The lock lever 2 is only required to prevent the front door 1 from being opened in the state where the front door 1 is locked (the open regulation position shown by the solid line in FIG. 2), and its shape, material, etc. are particularly limited. It is not a thing. The lock lever 2 here is made of metal, and has a hook-like shape with its tip projecting leftward (in the direction approaching the left wall of the device body 6). Specifically, the lock lever 2 here mainly includes a proximal end 21, a distal end 22, and a connecting portion 23 that links the proximal end 21 and the distal end 22.
　基端部２１は、ロックレバ回動軸５に取り付けられる部分である。基端部２１の一部は切り欠いてあり、これにより平面視して略矩形の切欠き部２１ａが形成されている。切欠き部２１ａには、付勢部材４の他端４３が挿入されている。 The base end portion 21 is a portion attached to the lock lever pivot shaft 5. A part of the base end portion 21 is cut away, whereby a substantially rectangular cutaway portion 21a is formed in plan view. The other end 43 of the biasing member 4 is inserted into the notch 21a.
　先端部２２は、前扉１が施錠されている状態（図２の実線で示す開放規制位置）で前扉１を開放した場合に、リミッタ３と係合する部分である。ここでの先端部２２は、平面視して略三角形状を呈しており、開放規制位置においてリミッタ３の後方に配置される。先端部２２は、開放規制位置においてリミッタ３の後端３２ａに対向する対向面２２ａを有する。対向面２２ａは、開放規制位置において第二屈曲部３２に直交する。言い換えると、対向面２２ａは、前扉１の開閉方向（ここでは前後方向）に直交する直交平面（ここでは上下方向の線分と左右方向の線分とで構成される平面）に存在する。対向面２２ａの先端側には、凹部２２ｂが形成されている。ここでの凹部２２ｂは、平面視して円弧状を呈している。凹部２２ｂの詳細は後記する。開放規制位置において、対向面２２ａとリミッタ３の後端３２ａとは当接していても当接していなくともどちらでもよい。 The front end portion 22 is a portion engaged with the limiter 3 when the front door 1 is opened in the state where the front door 1 is locked (the open regulation position shown by the solid line in FIG. 2). The front end portion 22 here has a substantially triangular shape in plan view, and is disposed behind the limiter 3 at the opening restricted position. The front end portion 22 has an opposing surface 22 a that faces the rear end 32 a of the limiter 3 in the release restriction position. The opposing surface 22a is orthogonal to the second bending portion 32 at the open regulation position. In other words, the facing surface 22 a is present in an orthogonal plane (here, a plane formed by line segments in the vertical direction and line segments in the horizontal direction) orthogonal to the opening / closing direction (front and rear direction here) of the front door 1. The recessed part 22b is formed in the front end side of the opposing surface 22a. The recess 22 b here has an arc shape in plan view. Details of the recess 22b will be described later. In the open control position, the facing surface 22a and the rear end 32a of the limiter 3 may or may not be in contact with each other.
　連結部２３は、基端部２１と先端部２２とを連結する部分である。連結部２３の形状や材質などは、特段限定されるものではない。ここでの連結部２３は、基端部２１及び先端部２２に比較して平面視した幅が狭くなっている。開放規制位置において、連結部２３とリミッタ３の第二屈曲部３２とは当接していても当接していなくともどちらでもよい。 The connection portion 23 is a portion that connects the proximal end portion 21 and the distal end portion 22. The shape, material, and the like of the connecting portion 23 are not particularly limited. The connecting portion 23 here has a narrower width in plan view than the proximal end portion 21 and the distal end portion 22. In the opening restricting position, the connecting portion 23 and the second bent portion 32 of the limiter 3 may or may not be in contact with each other.
≪第一実施形態に係るロック機構の動作≫
＜施錠状態での前扉の開放による動作＞
　図２の実線で示す開放規制位置で前扉１が開放された場合（前扉１が前方に引っ張られた場合）に、先端部２２の対向面２２ａとリミッタ３の後端３２ａとが当接し、前扉１の開放を規制する。以下では、対向面２２ａをリミッタ３との「当接領域」と呼ぶ場合がある。また、開放規制位置で前扉１が開放された場合に、リミッタ３の後端３２ａと当接する領域（ここでは対向面２２ａの根元側）を特に「第一当接領域Ｍ」と呼ぶ場合がある。 << Operation of Locking Mechanism According to First Embodiment >>
<Operation by opening the front door in the locked state>
When the front door 1 is opened at the open regulation position shown by the solid line in FIG. 2 (when the front door 1 is pulled forward), the opposing surface 22a of the front end 22 abuts on the rear end 32a of the limiter 3 , Regulate the opening of the front door 1. Hereinafter, the facing surface 22 a may be referred to as a “contact region” with the limiter 3. Further, when the front door 1 is opened at the opening restriction position, a region in contact with the rear end 32a of the limiter 3 (here, the base side of the facing surface 22a) may be particularly referred to as a "first contact region M" is there.
＜施錠状態での衝撃の付与による動作＞
　図３に示すように、開放規制位置において、先端部２２の対向面２２ａとリミッタ３の後端３２ａとを接触させた状態で装置本体６に連続した衝撃Ｐを加える場合を想定する。ここで、先端部２２の対向面２２ａとリミッタ３の後端３２ａとを接触させた状態とは、例えば、前扉１を前方に引っ張った状態である。また、連続した衝撃Ｐとは、例えば、故障時などに操作者が装置本体６や前扉１を連続して手で叩くことにより発生する衝撃である。 <Operation by application of impact in locked state>
As shown in FIG. 3, it is assumed that a continuous impact P is applied to the apparatus main body 6 in a state in which the facing surface 22 a of the tip end portion 22 and the rear end 32 a of the limiter 3 are in contact in the open control position. Here, the state in which the facing surface 22a of the leading end 22 and the rear end 32a of the limiter 3 are in a state in which the front door 1 is pulled forward, for example. Further, the continuous impact P is, for example, an impact generated when an operator continuously strikes the apparatus main body 6 or the front door 1 with a hand at the time of failure or the like.
　装置本体６に連続した衝撃Ｐを加えることにより、リミッタ３には振動が起こる。リミッタ３に発生した振動、及び対向面２２ａと後端３２ａとの摩擦によって、ロックレバ２とリミッタ３との当接位置が徐々に先端部２２の先端側（凹部２２ｂが形成される側）に移動する。これにより、ロックレバ２は付勢部材４の付勢力に抗してα２方向に回動する。そして、装置本体６に連続した衝撃Ｐを加え続けた場合に、図４に示すように、リミッタ３の後端３２ａが凹部２２ｂにはまることで係止し、衝撃Ｐを与えてもロックレバ２は回動しなくなる。前扉１に連続した衝撃Ｐを加えた場合も同様である。 Vibration is generated in the limiter 3 by applying a continuous impact P to the device body 6. The contact position between the lock lever 2 and the limiter 3 gradually moves to the tip side of the tip 22 (the side where the recess 22 b is formed) by the vibration generated in the limiter 3 and the friction between the opposing surface 22 a and the rear end 32 a. Do. Thereby, the lock lever 2 rotates in the α2 direction against the biasing force of the biasing member 4. Then, when the continuous impact P is continuously applied to the device main body 6, as shown in FIG. 4, the rear end 32a of the limiter 3 is engaged with the recess 22b, and the lock lever 2 is locked even if the impact P is applied. It will not rotate. The same applies to the case where a continuous impact P is applied to the front door 1.
　つまり、凹部２２ｂは、リミッタ３及びロックレバ２の少なくとも何れか一方に起こった振動を原因とするロックレバ２の回動を規制する役割を担うものである。以下では、ロックレバ２の対向面２２ａ（当接領域）に形成された凹部２２ｂを「回動規制部」と呼ぶ場合がある。また、振動を原因としてリミッタ３の後端３２ａが当接する対向面２２ａの領域（ここでは対向面２２ａの根元側以外）を特に「第二当接領域Ｎ」と呼ぶ場合がある。ここでは、第一当接領域Ｍと第二当接領域Ｎとは隣接しており、第二当接領域Ｎに凹部２２ｂが形成されている。 That is, the recess 22 b plays a role of restricting the rotation of the lock lever 2 caused by the vibration occurring in at least one of the limiter 3 and the lock lever 2. Below, the recessed part 22b formed in the opposing surface 22a (contact area | region) of the lock lever 2 may be called a "rotation control part." In addition, the area of the facing surface 22a (herein other than the root side of the facing surface 22a) where the rear end 32a of the limiter 3 contacts due to the vibration may be particularly referred to as a "second contact region N". Here, the first contact area M and the second contact area N are adjacent to each other, and a recess 22 b is formed in the second contact area N.
　ロックレバ２の凹部２２ｂは、リミッタ３及びロックレバ２の少なくとも何れか一方に起こった振動を原因とするロックレバ２の回動を規制するものであればよく、その形状・第二当接領域Ｎ内での位置・数・サイズなどは特段限定されるものではない。なお、本実施形態のように、対向面２２ａの先端側に凹部２２ｂを形成することで、各部品の部品精度に多少のばらつきがあったとしても、確実にリミッタ３の後端３２ａとロックレバ２の凹部２２ｂとを係止させることができる。また、本実施形態のように、凹部２２ｂを平面視して円弧状にすることで、リミッタ３の後端３２ａと凹部２２ｂとが係止した後において、ロックレバ２を比較的容易に図２に示す開放規制位置に戻すことができる。ロックレバ２を開放規制位置に戻すには、例えば、前扉１を後方に押し込んだり、施錠する方向に鍵を回すことで、リミッタ３の後端３２ａと凹部２２ｂとが係止した状態を解消させる。これにより、ロックレバ２は付勢部材４の付勢力によってα１方向に回動し、図２に示す開放規制位置に移動する。 The recess 22 b of the lock lever 2 may be any one that restricts rotation of the lock lever 2 caused by vibration occurring in at least one of the limiter 3 and the lock lever 2, and its shape in the second contact area N The position, number, size, etc. of are not particularly limited. As in the present embodiment, by forming the recess 22b on the tip end side of the facing surface 22a, the rear end 32a of the limiter 3 and the lock lever 2 can be reliably ensured even if there is some variation in the component accuracy of each component. Can be locked with the recess 22b. Further, as in the present embodiment, by forming the concave portion 22b in an arc shape in plan view, after the rear end 32a of the limiter 3 and the concave portion 22b are locked, the lock lever 2 can be relatively easily illustrated in FIG. It can be returned to the open regulation position shown. In order to return the lock lever 2 to the open regulation position, for example, the state where the rear end 32a of the limiter 3 and the recess 22b are locked is eliminated by pushing the front door 1 backward or turning the key in the locking direction. . Thus, the lock lever 2 is pivoted in the α1 direction by the biasing force of the biasing member 4 and is moved to the open regulation position shown in FIG.
　以上のように、第一実施形態に係るロック機構１０は、リミッタ３の後端３２ａに対向するロックレバ２の対向面２２ａに回動規制部としての凹部２２ｂが形成されている。そして、装置本体６に連続した衝撃Ｐを加えた場合でも、凹部２２ｂにリミッタ３の後端３２ａが係止し、ロックレバ２の回動が規制される。そのため、連続した衝撃Ｐを加えることによるロック機構１０の解除を防ぐことができる。 As described above, in the lock mechanism 10 according to the first embodiment, the recess 22 b as a rotation restricting portion is formed on the facing surface 22 a of the lock lever 2 facing the rear end 32 a of the limiter 3. Then, even when a continuous impact P is applied to the apparatus main body 6, the rear end 32a of the limiter 3 is locked in the recess 22b, and the rotation of the lock lever 2 is restricted. Therefore, the release of the lock mechanism 10 due to the application of the continuous impact P can be prevented.
［第二実施形態］
≪第二実施形態に係るロック機構の構成≫
　図５を参照して、第二実施形態に係るロック機構１０Ａの構成について説明する。ロック機構１０Ａは、ロックレバ２Ａと、リミッタ３と、付勢部材４と、ロックレバ回動軸５と、を主に備える。本実施形態では、ロックレバ２Ａの構成が第一実施形態と相違するため、相違する部分を中心に説明する。 Second Embodiment
<< Configuration of Locking Mechanism According to Second Embodiment >>
The configuration of the lock mechanism 10A according to the second embodiment will be described with reference to FIG. The lock mechanism 10A mainly includes a lock lever 2A, a limiter 3, a biasing member 4, and a lock lever pivot shaft 5. In the present embodiment, since the configuration of the lock lever 2A is different from that of the first embodiment, the differences will be mainly described.
　ロックレバ２Ａは、先端部２２Ａの構成が第一実施形態のロックレバ２と相違する。先端部２２Ａは、前扉１が施錠されている状態（図５の実線で示す開放規制位置）で前扉１を開放した場合に、リミッタ３と係合する部分である。ここでの先端部２２Ａは、平面視して略三角形状を呈しており、開放規制位置においてリミッタ３の後方に配置される。先端部２２Ａは、開放規制位置においてリミッタ３の後端３２ａに対向する対向面２２Ａａを有する。先端部２２Ａは、平面視して先端側が前方に傾いている。そのため、対向面２２Ａａは、開放規制位置において第二屈曲部３２に直交しておらず、前扉１の開閉方向（ここでは前後方向）に直交する直交平面（ここでは上下方向の線分と左右方向の線分とで構成される平面）に対して傾斜している。つまり、ここでの対向面２２Ａａは、前扉１の開閉方向に直交する直交平面に対して傾斜している傾斜部である。開放規制位置において、対向面２２Ａａとリミッタ３の後端３２ａとは当接していても当接していなくともどちらでもよい。 The lock lever 2A is different from the lock lever 2 of the first embodiment in the configuration of the tip 22A. The front end portion 22A is a portion engaged with the limiter 3 when the front door 1 is opened in a state where the front door 1 is locked (the open regulation position shown by the solid line in FIG. 5). The tip portion 22A here has a substantially triangular shape in a plan view, and is disposed behind the limiter 3 at the opening restricted position. The front end portion 22A has an opposing surface 22Aa that opposes the rear end 32a of the limiter 3 in the release restricted position. The distal end portion 22A is inclined forward in a plan view. Therefore, the facing surface 22Aa is not orthogonal to the second bending portion 32 at the opening restriction position, and is perpendicular to the opening / closing direction of the front door 1 (here, the front-rear direction). It is inclined with respect to the plane defined by the line segments of the direction). That is, the opposing surface 22Aa here is an inclined portion which is inclined with respect to an orthogonal plane orthogonal to the opening / closing direction of the front door 1. In the open regulation position, the facing surface 22Aa and the rear end 32a of the limiter 3 may or may not be in contact with each other.
≪第二実施形態に係るロック機構の動作≫
＜施錠状態での前扉の開放による動作＞
　図５の実線で示す開放規制位置で前扉１が開放された場合（前扉１が前方に引っ張られた場合）に、ロックレバ２Ａの先端部２２Ａの対向面２２Ａａとリミッタ３の後端３２ａとが当接し、前扉１の開放を規制する。 << Operation of Locking Mechanism According to Second Embodiment >>
<Operation by opening the front door in the locked state>
When the front door 1 is opened at the open regulation position shown by the solid line in FIG. 5 (when the front door 1 is pulled forward), the facing surface 22Aa of the front end 22A of the lock lever 2A and the rear end 32a of the limiter 3 Contacts and regulates the opening of the front door 1.
＜施錠状態での衝撃の付与による動作＞
　開放規制位置において、先端部２２Ａの対向面２２Ａａとリミッタ３の後端３２ａとを接触させた状態で装置本体６に連続した衝撃Ｐ（図３参照）を加える場合を想定する。装置本体６に連続した衝撃Ｐを加えることにより、リミッタ３には振動が起こる。リミッタ３に発生した振動、及び対向面２２Ａａと後端３２ａとの摩擦によって、ロックレバ２Ａとリミッタ３との当接位置が徐々に先端部２２Ａの先端側に移動する。これにより、ロックレバ２Ａは付勢部材４の付勢力に抗してα２方向に回動する。しかしながら、対向面２２Ａａは傾斜しており、対向面２２Ａａと後端３２ａとが接触することでロックレバ２Ａが開放規制位置に向かう方向（α１方向）へ力が働く。そのため、図６に示すように、衝撃を与えてもロックレバ２Ａは所定の位置で回動が停止する。前扉１に連続した衝撃Ｐを加えた場合も同様である。 <Operation by application of impact in locked state>
In the open regulation position, it is assumed that a continuous impact P (see FIG. 3) is applied to the apparatus main body 6 in a state in which the facing surface 22Aa of the tip 22A and the rear end 32a of the limiter 3 are in contact. Vibration is generated in the limiter 3 by applying a continuous impact P to the device body 6. The contact position between the lock lever 2A and the limiter 3 gradually moves to the tip side of the tip 22A due to the vibration generated in the limiter 3 and the friction between the facing surface 22Aa and the rear end 32a. Thereby, the lock lever 2A rotates in the α2 direction against the biasing force of the biasing member 4. However, the opposing surface 22Aa is inclined, and the contact of the opposing surface 22Aa with the rear end 32a causes a force to act in the direction (α1 direction) in which the lock lever 2A is directed to the release restriction position. Therefore, as shown in FIG. 6, even when an impact is applied, the rotation of the lock lever 2A is stopped at a predetermined position. The same applies to the case where a continuous impact P is applied to the front door 1.
　つまり、傾斜した対向面２２Ａａは、リミッタ３及びロックレバ２Ａの少なくとも何れか一方に起こった振動を原因とするロックレバ２Ａの回動を規制する役割を担うものである。以下では、ロックレバ２Ａに形成された傾斜した対向面２２Ａａを「回動規制部」と呼ぶ場合がある。ここでは対向面２２Ａａの全領域が傾斜しているが、対向面２２Ａａに形成される傾斜は、少なくとも第二当接領域Ｎに形成されていればよい。 That is, the inclined facing surface 22Aa plays a role of restricting the rotation of the lock lever 2A caused by the vibration generated in at least one of the limiter 3 and the lock lever 2A. Hereinafter, the inclined opposite surface 22Aa formed on the lock lever 2A may be referred to as a "rotation restricting portion". Here, the entire area of the facing surface 22Aa is inclined, but the inclination formed on the facing surface 22Aa may be at least formed in the second contact area N.
　以上のように、第二実施形態に係るロック機構１０Ａは、リミッタ３の後端３２ａに対向するロックレバ２Ａの対向面２２Ａａが傾斜している。そして、対向面２２Ａａと後端３２ａとが接触することでロックレバ２Ａが開放規制位置に向かう方向（α１方向）へ力が働く。そのため、連続した衝撃Ｐを加えることによるロック機構１０Ａの解除を防ぐことができる。 As described above, in the lock mechanism 10A according to the second embodiment, the facing surface 22Aa of the lock lever 2A facing the rear end 32a of the limiter 3 is inclined. Then, when the opposing surface 22Aa and the rear end 32a come into contact with each other, a force acts in the direction (α1 direction) in which the lock lever 2A is directed to the release control position. Therefore, it is possible to prevent the release of the lock mechanism 10A by applying the continuous impact P.
［第三実施形態］
≪第三実施形態に係るロック機構の構成≫
　図７を参照して、第三実施形態に係るロック機構１０Ｂの構成について説明する。ロック機構１０Ｂは、ロックレバ２Ｂと、リミッタ３と、付勢部材４と、ロックレバ回動軸５と、を主に備える。本実施形態では、ロックレバ２Ｂの構成が第一実施形態と相違するため、相違する部分を中心に説明する。 Third Embodiment
<< Configuration of Locking Mechanism According to Third Embodiment >>
The configuration of the lock mechanism 10B according to the third embodiment will be described with reference to FIG. The lock mechanism 10B mainly includes a lock lever 2B, a limiter 3, a biasing member 4, and a lock lever pivot shaft 5. In the present embodiment, since the configuration of the lock lever 2B is different from that of the first embodiment, the difference will be mainly described.
　ロックレバ２Ｂは、先端部２２Ｂの構成が第一実施形態のロックレバ２と相違する。先端部２２Ｂは、前扉１が施錠されている状態（図７の実線で示す開放規制位置）で前扉１を開放した場合に、リミッタ３と係合する部分である。ここでの先端部２２Ｂは、平面視して略三角形状を呈しており、開放規制位置においてリミッタ３の後方に配置される。先端部２２Ｂは、開放規制位置においてリミッタ３の後端３２ａに対向する根元側対向面２２Ｂａ及び先端部２２Ｂの先端側に形成される先端側対向面２２Ｂｃを有する。根元側対向面２２Ｂａは、開放規制位置において第二屈曲部３２に直交する。言い換えると、根元側対向面２２Ｂａは、前扉１の開閉方向（ここでは前後方向）に直交する直交平面（ここでは上下方向の線分と左右方向の線分とで構成される平面）に存在する。先端側対向面２２Ｂｃは、開放規制位置において第二屈曲部３２に直交しておらず、前扉１の開閉方向（ここでは前後方向）に直交する直交平面（ここでは上下方向の線分と左右方向の線分とで構成される平面）に対して傾斜している。つまり、ここでの先端側対向面２２Ｂｃは、前扉１の開閉方向に直交する直交平面に対して傾斜している傾斜部である。 The lock lever 2B is different from the lock lever 2 of the first embodiment in the configuration of the tip 22B. The front end portion 22B is a portion engaged with the limiter 3 when the front door 1 is opened in a state where the front door 1 is locked (the open regulation position shown by the solid line in FIG. 7). The tip portion 22B here has a substantially triangular shape in a plan view, and is disposed behind the limiter 3 at the open regulation position. The distal end portion 22B has a root side opposing surface 22Ba that faces the rear end 32a of the limiter 3 in the opening restricted position, and a distal end side opposing surface 22Bc formed on the distal end side of the distal end portion 22B. The base-side facing surface 22Ba is orthogonal to the second bending portion 32 in the release restriction position. In other words, the root-side facing surface 22Ba is present in an orthogonal plane (here, a plane formed by line segments in the vertical direction and line segments in the horizontal direction) orthogonal to the opening / closing direction of the front door 1 (here, the front-rear direction). Do. The front end side facing surface 22Bc is not orthogonal to the second bending portion 32 at the opening restriction position, and is a perpendicular plane (here, the line segment in the vertical direction and the left and right direction) orthogonal to the opening / closing direction of the front door 1 It is inclined with respect to the plane defined by the line segments of the direction). That is, the front end side facing surface 22Bc here is an inclined portion which is inclined with respect to an orthogonal plane orthogonal to the opening and closing direction of the front door 1.
　また、根元側対向面２２Ｂａと先端側対向面２２Ｂｃとの間には凹部２２Ｂｂが形成されている。つまり、先端部２２Ｂは、凹部２２Ｂｂを境にして先端側が前方に傾いている。ここでの凹部２２Ｂｂは、平面視して円弧状を呈している。開放規制位置において、根元側対向面２２Ｂａとリミッタ３の後端３２ａとは当接していても当接していなくともどちらでもよい。 Further, a recess 22Bb is formed between the base side facing surface 22Ba and the tip side facing surface 22Bc. That is, the tip end side of the tip end portion 22B is inclined forward with the recess 22Bb as a boundary. The recess 22Bb here has an arc shape in plan view. In the release restriction position, the base side facing surface 22Ba and the rear end 32a of the limiter 3 may or may not be in contact with each other.
≪第三実施形態に係るロック機構の動作≫
＜施錠状態での前扉の開放による動作＞
　図７の実線で示す開放規制位置で前扉１が開放された場合（前扉１が前方に引っ張られた場合）に、ロックレバ２Ｂの先端部２２Ｂの根元側対向面２２Ｂａとリミッタ３の後端３２ａとが当接し、前扉１の開放を規制する。 << Operation of Locking Mechanism According to Third Embodiment >>
<Operation by opening the front door in the locked state>
When the front door 1 is opened at the open regulation position shown by the solid line in FIG. 7 (when the front door 1 is pulled forward), the root side facing surface 22Ba of the distal end portion 22B of the lock lever 2B and the rear end of the limiter 3 32a abuts and regulates the opening of the front door 1.
＜施錠状態での衝撃の付与による動作＞
　開放規制位置において、先端部２２Ｂの根元側対向面２２Ｂａとリミッタ３の後端３２ａとを接触させた状態で装置本体６に連続した衝撃Ｐ（図３参照）を加える場合を想定する。装置本体６に連続した衝撃Ｐを加えることにより、リミッタ３には振動が起こる。リミッタ３に発生した振動、及び根元側対向面２２Ｂａと後端３２ａとの摩擦によって、ロックレバ２Ｂとリミッタ３との当接位置が徐々に先端部２２Ｂの先端側に移動する。これにより、ロックレバ２Ｂは付勢部材４の付勢力に抗してα２方向に回動する。そして、装置本体６に連続した衝撃Ｐを加え続けた場合に、図８に示すように、リミッタ３の後端３２ａが凹部２２Ｂｂにはまることで係止し、衝撃Ｐを与えてもロックレバ２は回動しなくなる。 <Operation by application of impact in locked state>
It is assumed that a continuous impact P (see FIG. 3) is applied to the apparatus main body 6 in a state in which the base-side facing surface 22Ba of the distal end portion 22B and the rear end 32a of the limiter 3 are in contact in the open control position. Vibration is generated in the limiter 3 by applying a continuous impact P to the device body 6. The contact position between the lock lever 2B and the limiter 3 gradually moves to the tip side of the tip 22B by the vibration generated in the limiter 3 and the friction between the base side facing surface 22Ba and the rear end 32a. Thereby, the lock lever 2B rotates in the α2 direction against the biasing force of the biasing member 4. Then, when the continuous impact P is continuously applied to the apparatus main body 6, as shown in FIG. 8, the rear end 32a of the limiter 3 is engaged by being fitted in the recess 22Bb, and the lock lever 2 It will not rotate.
　また、何らかの理由によりリミッタ３の後端３２ａが凹部２２Ｂｂに引っかからなかった場合や後端３２ａが凹部２２Ｂｂから外れてしまった場合でも、先端側対向面２２Ｂｃは傾斜している。そのため、先端側対向面２２Ｂｃと後端３２ａとが接触することでロックレバ２Ｂが開放規制位置に向かう方向（α１方向）へ力が働き、衝撃Ｐを与えてもロックレバ２Ｂは回動しなくなる。前扉１に連続した衝撃Ｐを加えた場合も同様である。 Further, even if the rear end 32a of the limiter 3 is not caught in the recess 22Bb or the rear end 32a is detached from the recess 22Bb for some reason, the tip side facing surface 22Bc is inclined. Therefore, the contact between the front end facing surface 22Bc and the rear end 32a causes the lock lever 2B to exert a force in the direction (α1 direction) toward the release control position, and the lock lever 2B does not rotate even if an impact P is applied. The same applies to the case where a continuous impact P is applied to the front door 1.
　つまり、凹部２２Ｂｂ及び傾斜した先端側対向面２２Ｂｃは、リミッタ３及びロックレバ２Ｂの少なくとも何れか一方に起こった振動を原因とするロックレバ２Ｂの回動を規制する役割を担うものである。以下では、ロックレバ２Ｂの根元側対向面２２Ｂａ（当接領域）に形成された凹部２２Ｂｂ及び傾斜した先端側対向面２２Ｂｃを「回動規制部」と呼ぶ場合がある。凹部２２Ｂｂ及び傾斜した先端側対向面２２Ｂｃは、少なくとも第二当接領域Ｎに形成されていればよい。凹部２２Ｂｂは、その形状・第二当接領域Ｎ内での位置・数・サイズなどは特段限定されるものではない。また、ここでは凹部２２Ｂｂと先端側対向面２２Ｂｃとが連続して形成されているが、距離を置いて形成されてもよい。 That is, the recess 22Bb and the inclined distal end side facing surface 22Bc play a role of restricting the rotation of the lock lever 2B caused by the vibration occurring in at least one of the limiter 3 and the lock lever 2B. Below, concave part 22Bb and inclined tip side opposing surface 22Bc formed in root side opposing surface 22Ba (contact area) of lock lever 2B may be called a "rotation control part." The recess 22 </ b> Bb and the inclined distal side facing surface 22 </ b> Bc may be formed at least in the second contact area N. The shape, the position, the number, the size, and the like of the recess 22Bb in the second contact region N are not particularly limited. Further, although the recess 22Bb and the tip side facing surface 22Bc are formed continuously here, they may be formed at a distance.
　以上のように、第三実施形態に係るロック機構１０Ｂは、リミッタ３の後端３２ａに対向するロックレバ２Ｂの根元側対向面２２Ｂａに回動規制部としての凹部２２Ｂｂが形成されている。そして、装置本体６に連続した衝撃Ｐを加えた場合でも、凹部２２Ｂｂにリミッタ３の後端３２ａが係止し、ロックレバ２の回動が規制される。そのため、連続した衝撃Ｐを加えることによるロック機構１０Ｂの解除を防ぐことができる。
　また、第三実施形態に係るロック機構１０Ｂは、何らかの理由によりリミッタ３の後端３２ａが凹部２２Ｂｂに引っかからなかった場合でも、先端側対向面２２Ｂｃは傾斜している。そして、先端側対向面２２Ｂｃと後端３２ａとが接触することでロックレバ２Ｂが開放規制位置に向かう方向（α１方向）へ力が働く。そのため、連続した衝撃Ｐを加えることによるロック機構１０Ｂの解除をより確実に防ぐことができる。 As described above, in the lock mechanism 10B according to the third embodiment, the recess 22Bb as the rotation restricting portion is formed in the base-side facing surface 22Ba of the lock lever 2B facing the rear end 32a of the limiter 3. Then, even when a continuous impact P is applied to the apparatus main body 6, the rear end 32a of the limiter 3 is locked in the recess 22Bb, and the rotation of the lock lever 2 is restricted. Therefore, it is possible to prevent the release of the lock mechanism 10B by applying the continuous impact P.
Further, in the lock mechanism 10B according to the third embodiment, even if the rear end 32a of the limiter 3 is not caught in the recess 22Bb for any reason, the tip side facing surface 22Bc is inclined. The contact between the front end facing surface 22Bc and the rear end 32a causes a force to act in the direction (α1 direction) of the lock lever 2B toward the release restriction position. Therefore, the release of the lock mechanism 10B due to the application of the continuous impact P can be more reliably prevented.
［第四実施形態］
≪第四実施形態に係るロック機構の構成≫
　図９を参照して、第四実施形態に係るロック機構１０Ｃの構成について説明する。ロック機構１０Ｃは、ロックレバ２Ｃと、リミッタ３と、付勢部材４と、ロックレバ回動軸５と、を主に備える。本実施形態では、ロックレバ２Ｃの構成が第一実施形態と相違するため、相違する部分を中心に説明する。 Fourth Embodiment
<< Configuration of Locking Mechanism According to Fourth Embodiment >>
The configuration of a lock mechanism 10C according to the fourth embodiment will be described with reference to FIG. The lock mechanism 10C mainly includes a lock lever 2C, a limiter 3, a biasing member 4, and a lock lever pivot shaft 5. In the present embodiment, since the configuration of the lock lever 2C is different from that of the first embodiment, the different portions will be mainly described.
　ロックレバ２Ｃは、先端部２２Ｃの構成が第一実施形態のロックレバ２と相違する。先端部２２Ｃは、前扉１が施錠されている状態（図９の実線で示す開放規制位置）で前扉１を開放した場合に、リミッタ３と係合する部分である。ここでの先端部２２Ｃは、平面視して略三角形状を呈しており、開放規制位置においてリミッタ３の後方に配置される。先端部２２Ｃは、開放規制位置においてリミッタ３の後端３２ａに対向する対向面２２Ｃａを有する。対向面２２Ｃａは、開放規制位置において第二屈曲部３２に直交する。言い換えると、対向面２２Ｃａは、前扉１の開閉方向（ここでは前後方向）に直交する直交平面（ここでは上下方向の線分と左右方向の線分とで構成される平面）に存在する。対向面２２Ｃａの先端側には、凸部２２Ｃｂが形成されている。これにより、先端部２２Ｃは、鉤状を呈している。開放規制位置において、対向面２２Ｃａとリミッタ３の後端３２ａとは当接していても当接していなくともどちらでもよい。 The lock lever 2C is different from the lock lever 2 of the first embodiment in the configuration of the tip 22C. The front end portion 22C is a portion engaged with the limiter 3 when the front door 1 is opened in a state where the front door 1 is locked (the open regulation position shown by the solid line in FIG. 9). The tip portion 22C here has a substantially triangular shape in plan view, and is disposed behind the limiter 3 at the opening restricted position. The front end portion 22C has an opposing surface 22Ca that opposes the rear end 32a of the limiter 3 in the release restriction position. The opposing surface 22Ca is orthogonal to the second bending portion 32 in the release restriction position. In other words, the facing surface 22Ca is present in an orthogonal plane (here, a plane formed by line segments in the vertical direction and line segments in the left-right direction) orthogonal to the opening / closing direction of the front door 1 (here, the front-rear direction). Convex part 22Cb is formed in the tip side of opposed face 22Ca. Thus, the tip 22C has a bowl shape. In the open regulation position, the facing surface 22Ca and the rear end 32a of the limiter 3 may or may not be in contact with each other.
≪第四実施形態に係るロック機構の動作≫
＜施錠状態での前扉の開放による動作＞
　図９の実線で示す開放規制位置で前扉１が開放された場合（前扉１が前方に引っ張られた場合）に、ロックレバ２Ｃの先端部２２Ｃの対向面２２Ｃａとリミッタ３の後端３２ａとが当接し、前扉１の開放を規制する。 << Operation of Locking Mechanism According to Fourth Embodiment >>
<Operation by opening the front door in the locked state>
When the front door 1 is opened at the open regulation position shown by the solid line in FIG. 9 (when the front door 1 is pulled forward), the facing surface 22Ca of the front end 22C of the lock lever 2C and the rear end 32a of the limiter 3 Contacts and regulates the opening of the front door 1.
＜施錠状態での衝撃の付与による動作＞
　開放規制位置において、先端部２２Ｃの対向面２２Ｃａとリミッタ３の後端３２ａとを接触させた状態で装置本体６に連続した衝撃Ｐ（図３参照）を加える場合を想定する。装置本体６に連続した衝撃Ｐを加えることにより、リミッタ３には振動が起こる。リミッタ３に発生した振動、及び対向面２２Ｃａと後端３２ａとの摩擦によって、ロックレバ２Ｃとリミッタ３との当接位置が徐々に先端部２２Ｃの先端側に移動する。これにより、ロックレバ２Ｃは付勢部材４の付勢力に抗してα２方向に回動する。そして、装置本体６に連続した衝撃Ｐを加え続けた場合に、図１０に示すように、リミッタ３の後端３２ａが凸部２２Ｃｂに引っかかることで係止し、衝撃Ｐを与えてもロックレバ２Ｃは回動しなくなる。前扉１に連続した衝撃Ｐを加えた場合も同様である。 <Operation by application of impact in locked state>
In the open regulation position, it is assumed that a continuous impact P (see FIG. 3) is applied to the apparatus main body 6 in a state in which the opposing surface 22Ca of the tip 22C and the rear end 32a of the limiter 3 are in contact. Vibration is generated in the limiter 3 by applying a continuous impact P to the device body 6. The contact position between the lock lever 2C and the limiter 3 gradually moves to the tip side of the tip 22C due to the vibration generated in the limiter 3 and the friction between the facing surface 22Ca and the rear end 32a. Thereby, the lock lever 2C rotates in the α2 direction against the biasing force of the biasing member 4. Then, when the continuous impact P is continuously applied to the device main body 6, as shown in FIG. 10, the rear end 32a of the limiter 3 is engaged by being caught by the convex portion 22Cb, and the lock lever 2C is locked even if the impact P is applied. Will not rotate. The same applies to the case where a continuous impact P is applied to the front door 1.
　つまり、凸部２２Ｃｂは、リミッタ３及びロックレバ２Ｃの少なくとも何れか一方に起こった振動を原因とするロックレバ２Ｃの回動を規制する役割を担うものである。以下では、リミッタ３の対向面２２Ｃａ（当接領域）に形成された凸部２２Ｃｂを「回動規制部」と呼ぶ場合がある。凸部２２Ｃｂは、少なくとも第二当接領域Ｎに形成されていればよい。凸部２２Ｃｂは、その形状・第二当接領域Ｎ内での位置・数・サイズなどは特段限定されるものではない。 That is, the convex portion 22Cb plays a role of restricting the rotation of the lock lever 2C caused by the vibration generated in at least one of the limiter 3 and the lock lever 2C. Below, convex part 22Cb formed in opposing surface 22Ca (contact area) of limiter 3 may be called a "rotation control part." The convex portion 22Cb may be formed at least in the second contact area N. The shape, the position, the number, the size, and the like of the convex portion 22Cb in the second contact region N are not particularly limited.
　以上のように、第四実施形態に係るロック機構１０Ｃは、リミッタ３の後端３２ａに対向するロックレバ２Ｃの対向面２２Ｃａに回動規制部としての凸部２２Ｃｂが形成されている。そして、装置本体６に連続した衝撃Ｐを加えた場合でも、凸部２２Ｃｂにリミッタ３の後端３２ａが係止し、ロックレバ２Ｃの回動が規制される。そのため、連続した衝撃Ｐを加えることによるロック機構１０Ｃの解除を防ぐことができる。 As described above, in the lock mechanism 10C according to the fourth embodiment, the convex portion 22Cb as the rotation restricting portion is formed on the facing surface 22Ca of the lock lever 2C facing the rear end 32a of the limiter 3. Then, even when a continuous impact P is applied to the device body 6, the rear end 32a of the limiter 3 is engaged with the convex portion 22Cb, and the rotation of the lock lever 2C is restricted. Therefore, it is possible to prevent the release of the lock mechanism 10C by applying the continuous impact P.
［第五実施形態］
≪第五実施形態に係るロック機構の構成≫
　図１１を参照して、第五実施形態に係るロック機構１０Ｄの構成について説明する。ロック機構１０Ｄは、ロックレバ２Ｄと、リミッタ３と、付勢部材４と、ロックレバ回動軸５と、を主に備える。本実施形態では、ロックレバ２Ｄの構成が第一実施形態と相違するため、相違する部分を中心に説明する。 Fifth Embodiment
<< Configuration of Locking Mechanism According to Fifth Embodiment >>
The configuration of the lock mechanism 10D according to the fifth embodiment will be described with reference to FIG. The lock mechanism 10D mainly includes a lock lever 2D, a limiter 3, a biasing member 4, and a lock lever pivot shaft 5. In the present embodiment, since the configuration of the lock lever 2D is different from that of the first embodiment, the difference will be mainly described.
　ロックレバ２Ｄは、先端部２２Ｄの構成が第一実施形態のロックレバ２と相違する。先端部２２Ｄは、前扉１が施錠されている状態（図１１の実線で示す開放規制位置）で前扉１を開放した場合に、リミッタ３と係合する部分である。ここでの先端部２２Ｄは、平面視して略三角形状を呈しており、開放規制位置においてリミッタ３の後方に配置される。先端部２２Ｄは、開放規制位置においてリミッタ３の後端３２ａに対向する対向面２２Ｄａを有する。先端部２２Ｄは、平面視して先端側が前方に傾いている。そのため、対向面２２Ｄａは、開放規制位置において第二屈曲部３２に直交しておらず、前扉１の開閉方向（ここでは前後方向）に直交する直交平面（ここでは上下方向の線分と左右方向の線分とで構成される平面）に対して傾斜している。つまり、ここでの対向面２２Ｄａは、前扉１の開閉方向に直交する直交平面に対して傾斜している傾斜部である。対向面２２Ｄａの先端側には、凸部２２Ｄｂが形成されている。これにより、先端部２２Ｄは、鉤状を呈している。開放規制位置において、対向面２２Ｄａとリミッタ３の後端３２ａとは当接していても当接していなくともどちらでもよい。 The lock lever 2D is different from the lock lever 2 of the first embodiment in the configuration of the tip 22D. The front end portion 22D is a portion engaged with the limiter 3 when the front door 1 is opened in a state where the front door 1 is locked (the open regulation position shown by the solid line in FIG. 11). The tip portion 22D here has a substantially triangular shape in a plan view, and is disposed behind the limiter 3 at the opening restricted position. The front end portion 22D has an opposing surface 22Da that faces the rear end 32a of the limiter 3 in the release restriction position. The front end portion of the front end portion 22D is inclined forward in plan view. Therefore, the facing surface 22Da is not orthogonal to the second bending portion 32 at the opening restriction position, and is perpendicular to the opening / closing direction of the front door 1 (here, the front and rear direction). It is inclined with respect to the plane defined by the line segments of the direction). That is, opposing surface 22Da here is an inclination part which inclines with respect to the orthogonal plane orthogonal to the opening and closing direction of the front door 1. FIG. A convex portion 22Db is formed on the tip end side of the facing surface 22Da. Thereby, tip part 22D is exhibiting bowl shape. In the open regulation position, the facing surface 22Da and the rear end 32a of the limiter 3 may or may not be in contact with each other.
≪第五実施形態に係るロック機構の動作≫
＜施錠状態での前扉の開放による動作＞
　図１１の実線で示す開放規制位置で前扉１が開放された場合（前扉１が前方に引っ張られた場合）に、ロックレバ２Ｄの先端部２２Ｄの対向面２２Ｄａとリミッタ３の後端３２ａとが当接し、前扉１の開放を規制する。 << Operation of Locking Mechanism According to Fifth Embodiment >>
<Operation by opening the front door in the locked state>
When the front door 1 is opened at the open regulation position shown by the solid line in FIG. 11 (when the front door 1 is pulled forward), the facing surface 22Da of the front end 22D of the lock lever 2D and the rear end 32a of the limiter 3 Contacts and regulates the opening of the front door 1.
＜施錠状態での衝撃の付与による動作＞
　開放規制位置において、先端部２２Ｄの対向面２２Ｄａとリミッタ３の後端３２ａとを接触させた状態で装置本体６に連続した衝撃Ｐ（図３参照）を加える場合を想定する。装置本体６に連続した衝撃Ｐを加えることにより、リミッタ３には振動が起こる。リミッタ３に発生した振動、及び対向面２２Ｄａと後端３２ａとの摩擦によって、ロックレバ２Ｄとリミッタ３との当接位置が徐々に先端部２２Ｄの先端側に移動する。これにより、ロックレバ２Ｄは付勢部材４の付勢力に抗してα２方向に回動する。しかしながら、対向面２２Ｄａは傾斜しており、対向面２２Ｄａと後端３２ａとが接触することでロックレバ２Ｄが開放規制位置に向かう方向（α１方向）へ力が働く。そのため、衝撃Ｐを与えてもロックレバ２は所定の位置で回動が停止する。 <Operation by application of impact in locked state>
It is assumed that a continuous impact P (see FIG. 3) is applied to the apparatus main body 6 in a state in which the facing surface 22Da of the leading end 22D and the rear end 32a of the limiter 3 are in contact at the open control position. Vibration is generated in the limiter 3 by applying a continuous impact P to the device body 6. The contact position between the lock lever 2D and the limiter 3 is gradually moved to the tip side of the tip 22D by the vibration generated in the limiter 3 and the friction between the facing surface 22Da and the rear end 32a. Thereby, the lock lever 2D rotates in the α2 direction against the biasing force of the biasing member 4. However, the opposing surface 22Da is inclined, and the contact of the opposing surface 22Da with the rear end 32a causes a force to act in the direction (α1 direction) in which the lock lever 2D is directed to the release restriction position. Therefore, even if an impact P is applied, the rotation of the lock lever 2 is stopped at a predetermined position.
　また、何らかの理由によりリミッタ３の後端３２ａと対向面２２Ｄａとが当接する位置が外側に移動し続ける場合でも、図１２に示すように、リミッタ３の後端３２ａが凸部２２Ｄｂに引っかかることで係止し、衝撃Ｐを与えてもロックレバ２Ｄは回動しなくなる。前扉１に連続した衝撃Ｐを加えた場合も同様である。 Further, even if the position where the rear end 32a of the limiter 3 and the facing surface 22D abut each other continues to move outward due to any reason, the rear end 32a of the limiter 3 is caught on the convex portion 22Db as shown in FIG. The locking lever 2D does not rotate even if it is locked and an impact P is applied. The same applies to the case where a continuous impact P is applied to the front door 1.
　つまり、傾斜した対向面２２Ｄａ及び凸部２２Ｄｂは、リミッタ３及びロックレバ２Ｄの少なくとも何れか一方に起こった振動を原因とするロックレバ２Ｄの回動を規制する役割を担うものである。以下では、ロックレバ２Ｄに形成された傾斜した対向面２２Ｄａ及び対向面２２Ｄａに形成された凸部２２Ｄｂを「回動規制部」と呼ぶ場合がある。傾斜した対向面２２Ｄａ及び凸部２２Ｄｂは、少なくとも第二当接領域Ｎに形成されていればよい。凸部２２Ｄｂは、その形状・第二当接領域Ｎ内での位置・数・サイズなどは特段限定されるものではない。 That is, the inclined facing surface 22Da and the convex portion 22Db play a role of restricting the rotation of the lock lever 2D caused by the vibration occurring in at least one of the limiter 3 and the lock lever 2D. Hereinafter, the inclined opposing surface 22Da formed on the lock lever 2D and the convex portion 22Db formed on the opposing surface 22Da may be referred to as a "rotation restricting portion". The inclined facing surface 22Da and the convex portion 22Db may be formed at least in the second contact area N. The shape, the position, the number, the size, and the like of the convex portion 22Db are not particularly limited.
　以上のように、第五実施形態に係るロック機構１０Ｄは、リミッタ３の後端３２ａに対向するロックレバ２Ｄの対向面２２Ｄａが傾斜している。そして、対向面２２Ｄａと後端３２ａとが接触することでロックレバ２Ｄが開放規制位置に向かう方向（α１方向）へ力が働く。そのため、連続した衝撃Ｐを加えることによるロック機構１０Ｄの解除を防ぐことができる。
　また、第五実施形態に係るロック機構１０Ｄは、何らかの理由によりリミッタ３の後端３２ａと対向面２２Ｄａとが当接する位置が外側に移動した場合でも、リミッタ３の後端３２ａに対向するロックレバ２Ｄの対向面２２Ｄａに回動規制部としての凸部２２Ｄｂが形成されている。そして、装置本体６に連続した衝撃Ｐを加えた場合でも、凸部２２Ｄｂにリミッタ３の後端３２ａが係止し、ロックレバ２Ｄの回動が規制される。そのため、連続した衝撃Ｐを加えることによるロック機構１０Ｄの解除を防ぐことができる。 As described above, in the lock mechanism 10D according to the fifth embodiment, the facing surface 22Da of the lock lever 2D facing the rear end 32a of the limiter 3 is inclined. Then, when the opposing surface 22Da and the rear end 32a come into contact with each other, a force acts in a direction (α1 direction) in which the lock lever 2D moves to the release control position. Therefore, the release of the lock mechanism 10D due to the application of the continuous impact P can be prevented.
In the lock mechanism 10D according to the fifth embodiment, the lock lever 2D facing the rear end 32a of the limiter 3 even when the position where the rear end 32a of the limiter 3 abuts the opposing surface 22Da moves outward for any reason The convex part 22Db as a rotation control part is formed in the opposing surface 22Da. Then, even when a continuous impact P is applied to the apparatus body 6, the rear end 32a of the limiter 3 is engaged with the convex portion 22Db, and the rotation of the lock lever 2D is restricted. Therefore, the release of the lock mechanism 10D due to the application of the continuous impact P can be prevented.
［変形例］
　以上、本発明の各実施形態について説明したが、本発明はこれに限定されるものではなく、特許請求の範囲の趣旨を変えない範囲で実施することができる。 [Modification]
As mentioned above, although each embodiment of this invention was described, this invention is not limited to this, It can implement in the range which does not change the meaning of a claim.
　第一実施形態に係るロック機構１０は、連続した衝撃Ｐによる解除を防ぐことができた。しかしながら、図１３に示すように、第一実施形態に係るロック機構１０では、装置本体６に大きな衝撃Ｑが加えられた場合（例えば、ハンマー等を用いて衝撃が加えられた場合）に、その衝撃Ｑがロックレバ２に伝わり、ロックレバ２が開放許容位置に移動してしまう虞があった。つまり、第一実施形態に係るロック機構１０では、連結部２３とリミッタ３の第二屈曲部３２との位置関係が特に限定されていなかったので、装置本体６に加えられた衝撃Ｑがリミッタ３の第二屈曲部３２を介してロックレバ２の連結部２３に伝わってしまう虞があった。第二実施形態～第五実施形態に係るロック機構１０Ａ～１０Ｄについても同様である。 The lock mechanism 10 according to the first embodiment can prevent the release due to the continuous impact P. However, as shown in FIG. 13, in the lock mechanism 10 according to the first embodiment, when a large impact Q is applied to the device body 6 (for example, when an impact is applied using a hammer or the like), The impact Q is transmitted to the lock lever 2 and there is a possibility that the lock lever 2 may move to the open permitting position. That is, in the lock mechanism 10 according to the first embodiment, the positional relationship between the connecting portion 23 and the second bending portion 32 of the limiter 3 is not particularly limited. There is a possibility that the connection portion 23 of the lock lever 2 may be transmitted through the second bent portion 32 of the second embodiment. The same applies to the lock mechanisms 10A to 10D according to the second to fifth embodiments.
［第一実施形態の変形例（第一変形例）］
≪第一実施形態の変形例に係るロック機構の構成≫
　図１４を参照して、第一実施形態の変形例に係るロック機構１０Ｅの構成について説明する。ロック機構１０Ｅは、ロックレバ２と、リミッタ３と、付勢部材４と、ロックレバ回動軸５と、を主に備える。本変形例では、ロックレバ２を設置する位置が第一実施形態と相違するため、相違する部分を中心に説明する。 Modification of First Embodiment (First Modification)
<< Configuration of Locking Mechanism According to Modification of First Embodiment >>
The configuration of a lock mechanism 10E according to a modification of the first embodiment will be described with reference to FIG. The lock mechanism 10E mainly includes a lock lever 2, a limiter 3, a biasing member 4, and a lock lever pivot shaft 5. In this modification, since the position at which the lock lever 2 is installed is different from that of the first embodiment, the difference will be mainly described.
　ロック機構１０Ｅでは、開放規制位置において、ロックレバ２とリミッタ３との間に装置本体６に加えられた衝撃Ｑ（図１３参照）を伝わらなくするための隙間Ｈを設けてある。隙間Ｈを設ける位置は特段限定されるものではないが、例えば衝撃Ｑが加えられる場所や大きさ、ロックレバ２とリミッタ３との位置関係などにより決定される。ここでは、装置本体６の左壁に衝撃Ｑが加えられることを想定しているので、リミッタ３の延長線上であるロックレバ２の連結部２３とリミッタ３の第二屈曲部３２との間に隙間Ｈを設けてある。隙間Ｈの距離は、装置本体６に加えた衝撃Ｑがロックレバ２に伝わらないものであればよい。つまり、ここでの隙間Ｈの距離は、装置本体６に衝撃Ｑが加えられても、ロックレバ２の連結部２３とリミッタ３の第二屈曲部３２とが接触しないものである。なお、ロックレバ２を図１４に示す開放規制位置にとどめておくために、例えばリミッタ３とは別部材（図示せず）を用いて、ロックレバ２のα１方向の回動を抑えるようにしてもよい。 In the lock mechanism 10E, a gap H is provided between the lock lever 2 and the limiter 3 so as not to transmit an impact Q (see FIG. 13) applied to the apparatus main body 6 in the open regulation position. The position where the gap H is provided is not particularly limited, but is determined, for example, by the location and size to which the shock Q is applied, the positional relationship between the lock lever 2 and the limiter 3, and the like. Here, it is assumed that the impact Q is applied to the left wall of the device body 6, so the gap between the connecting portion 23 of the lock lever 2 and the second bending portion 32 of the limiter 3 which is an extension of the limiter 3 H is provided. The distance of the gap H may be such that the shock Q applied to the device body 6 is not transmitted to the lock lever 2. That is, the distance H of the gap H here is such that the connecting portion 23 of the lock lever 2 and the second bending portion 32 of the limiter 3 do not contact even when the shock Q is applied to the device body 6. In addition, in order to keep the lock lever 2 in the open regulation position shown in FIG. 14, for example, a separate member (not shown) from the limiter 3 may be used to suppress the rotation of the lock lever 2 in the α1 direction. .
≪第一実施形態の変形例に係るロック機構の動作≫
＜施錠状態での前扉の開放による動作＞
　図１４の実線で示す開放規制位置で前扉１が開放された場合（前扉１が前方に引っ張られた場合）に、先端部２２の対向面２２ａとリミッタ３の後端３２ａとが当接し、前扉１の開放を規制する。 << Operation of Locking Mechanism According to Modification of First Embodiment >>
<Operation by opening the front door in the locked state>
When the front door 1 is opened at the open regulation position shown by the solid line in FIG. 14 (when the front door 1 is pulled forward), the opposing surface 22a of the front end 22 abuts on the rear end 32a of the limiter 3 , Regulate the opening of the front door 1.
＜施錠状態での衝撃の付与による動作＞
　図１４に示す開放規制位置において、装置本体６に大きな衝撃Ｑ（図１３参照）を加える場合を想定する。ロックレバ２の連結部２３とリミッタ３の第二屈曲部３２との間に隙間Ｈを設けることによって、装置本体６に大きな衝撃Ｑを加えた場合でも、ロックレバ２に衝撃Ｑは伝わらない。そのため、装置本体６に大きな衝撃Ｑを加えても、ロックレバ２が開放許容位置（図１４の仮想線で示す位置）に移動せず、前扉１の開放は規制されたままとなる。 <Operation by application of impact in locked state>
It is assumed that a large impact Q (see FIG. 13) is applied to the device body 6 at the open regulation position shown in FIG. By providing the gap H between the connecting portion 23 of the lock lever 2 and the second bending portion 32 of the limiter 3, even if a large impact Q is applied to the device body 6, the impact Q is not transmitted to the lock lever 2. Therefore, even if a large impact Q is applied to the apparatus main body 6, the lock lever 2 does not move to the open allowable position (the position shown by the phantom line in FIG. 14), and the opening of the front door 1 remains restricted.
　また、図１４に示す開放規制位置において、装置本体６に連続した衝撃Ｐ（図３参照）を加える場合を想定する。この場合、第一実施形態と同様に、図１５に示すように、リミッタ３の後端３２ａが凹部２２ｂにはまることで係止し、衝撃Ｐを与えてもロックレバ２は回動しなくなる。 Further, it is assumed that a continuous impact P (see FIG. 3) is applied to the apparatus main body 6 at the open regulation position shown in FIG. In this case, similarly to the first embodiment, as shown in FIG. 15, the rear end 32a of the limiter 3 is engaged by being fitted in the recess 22b, and the lock lever 2 does not rotate even if an impact P is applied.
　以上のように、第一実施形態の変形例に係るロック機構１０Ｅは、ロックレバ２とリミッタ３との間に衝撃Ｑを伝わらなくするための隙間Ｈが設けてある。そのため、大きな衝撃Ｑが加わったとしても、ロックレバ２に衝撃Ｑは伝わらないので、ロックレバ２が開放許容位置（図１４の仮想線で示す位置）に移動せず、ロック機構１０Ｅの解除を防ぐことができる。
　また、第一実施形態の変形例に係るロック機構１０Ｅは、リミッタ３の後端３２ａに対向するロックレバ２の対向面２２ａに回動規制部としての凹部２２ｂが形成されている。そして、装置本体６に連続した衝撃Ｐを加えた場合でも、凹部２２ｂにリミッタ３の後端３２ａが係止し、ロックレバ２の回動が規制される。そのため、連続した衝撃Ｐを加えることによるロック機構１０Ｅの解除を防ぐことができる。 As described above, in the lock mechanism 10E according to the modification of the first embodiment, the gap H for preventing transmission of the shock Q is provided between the lock lever 2 and the limiter 3. Therefore, even if a large impact Q is applied, the impact Q is not transmitted to the lock lever 2, so the lock lever 2 does not move to the open allowable position (the position shown by the phantom line in FIG. 14), and prevents the release of the lock mechanism 10E. Can.
In the lock mechanism 10E according to the modification of the first embodiment, a recess 22b as a rotation restricting portion is formed on the facing surface 22a of the lock lever 2 facing the rear end 32a of the limiter 3. Then, even when a continuous impact P is applied to the apparatus main body 6, the rear end 32a of the limiter 3 is locked in the recess 22b, and the rotation of the lock lever 2 is restricted. Therefore, it is possible to prevent the release of the lock mechanism 10E by applying the continuous impact P.

A lock mechanism 10F according to a modification of the second embodiment is shown in FIG. A lock mechanism 10G according to a modification of the third embodiment is shown in FIG. A lock mechanism 10H according to a modification of the fourth embodiment is shown in FIG. A lock mechanism 10I according to a modification of the fifth embodiment is shown in FIG. These lock mechanisms 10F to 10I do not transmit the shock Q (see FIG. 13) applied to the apparatus main body 6 between the lock levers 2A to 2D and the limiter 3 similarly to the lock mechanism 10E according to the first modification. A clearance H is provided for this purpose.
　以上のように、第二実施形態～第五実施形態の変形例に係るロック機構１０Ｆ～１０Ｉは、各実施形態で説明した効果に加えて、大きな衝撃Ｑが加わった場合でもロック機構１０Ｆ～１０Ｉの解除を防ぐことができるという効果を得ることができる。 As described above, the lock mechanisms 10F to 10I according to the modifications of the second to fifth embodiments have the lock mechanisms 10F to 10I in addition to the effects described in the respective embodiments even when a large impact Q is applied.
