In other words, the above latch device switches the engagement body 37 from the unlocked state to the locked state by the pushing force of the striker 62 against the sliding body 30, and from the locked state by the next pushing force of the striker 62 against the sliding body 30. Switch to the unlocked state. At that time, the upper side of the spring member 45 is locked to a projecting piece provided in the lower middle of the engaging body 37, and the spring member 45 is engaged while accumulating urging force in the process of the sliding body 30 being pushed and moved to the back. The united body 37 is rotated counterclockwise in FIGS. 10A and 10B with the shaft portion 37a as a fulcrum, and can be switched from the unlocked state to the locking direction.
使用例としては、本体側にラッチ装置を取り付け、扉側にストライカー62を設けた場合だと、図10(b)が扉を本体に係止(ロック)した状態となり、扉側のストライカー62が本体側のラッチ装置を構成している係合体37により係止される。この係止は、扉が再び本体側へ押されると、トレース部材6がカム溝5の係止溝から外れて図10(a)のごとく係止解除される。このような構造は特許文献2や3のラッチ装置も同じ。
As an example of use, when a latch device is attached to the main body side and a striker 62 is provided on the door side, FIG. 10B shows a state where the door is locked (locked) to the main body. It is locked by an engaging body 37 constituting a latch device on the main body side. When the door is pushed again toward the main body, the trace member 6 is released from the locking groove of the cam groove 5 and is released as shown in FIG. Such a structure is the same in the latch devices of Patent Documents 2 and 3.
上記したラッチ装置では、例えば、扉を閉じた係止状態において、扉を本体から離間する方向の外力が作用すると、係合体37がストライカー62の引き抜き方向の応力を受けて摺動体側開口33を区画している枠部の内面に圧接される。この構造では、そのときに生じる摩擦力により係合体37とストライカー62との間に所定の係止力、つまり係止状態を維持しようとする力(無理抜き荷重)が得られるようにし、扉が不用意に開くという事態を防止している。
In the above-described latch device, for example, when an external force acting in a direction in which the door is separated from the main body acts in a locked state where the door is closed, the engaging body 37 receives the stress in the pulling direction of the striker 62 and opens the sliding body side opening 33. It is in pressure contact with the inner surface of the partitioning frame. In this structure, a predetermined locking force, that is, a force for maintaining the locked state (unreasonable load) is obtained between the engaging body 37 and the striker 62 by the frictional force generated at that time, and the door is The situation of inadvertent opening is prevented.
ところが、そのような無理抜き荷重は、係合体側爪部39と開口33とが接する面同士の表面粗さやヒケ度合いなどの外的要因に左右されて一定に維持し難かった。また、従来構造では、無理抜き荷重を高くするため係合体側爪部39の形状にアンダーカット段差を設けると、爪部39が開口33側に引っかかるなど通常時の正常な作動が損なわれ易くなる。なお、扉に対し無理抜き荷重より大きな外力が作用した場合は、係合体37が爪部39を突当部32上から退行するよう回転、つまり係止状態から係止解除方向に切り換えられるが、カム溝やトレース部材の破壊要因となる。
However, it has been difficult to maintain such a force-free load constant due to external factors such as surface roughness and degree of sinking between the surfaces where the engaging body side claw portion 39 and the opening 33 are in contact with each other. Further, in the conventional structure, if an undercut step is provided in the shape of the engaging body side claw portion 39 in order to increase the force of unloading, normal operation such as the claw portion 39 being caught on the opening 33 side is likely to be impaired. . When an external force larger than the force with which the door is forcibly applied is applied to the door, the engaging body 37 is rotated so that the claw portion 39 retracts from the abutting portion 32, that is, the locked state is switched to the unlocking direction. It becomes a cause of destruction of cam grooves and trace members.
以上のような対策として、本出願人は特許文献2や3に開示されている構成などを開発してきた。本発明の目的は、それらの対策に比べ、特に無理抜き荷重を高くしたり用途に応じた大きさに確実かつ的確に変更可能にして、設計自由度を向上し用途拡大を図ることにある。

本発明では、係合体が被係脱部材を係止した(トレース部材がカム溝に係止された)係止状態で、被係脱部材を介して無理抜き方向に一定値以上の負荷を受けると、係合体が係止解除方向に回転しようとし、その際に板ばねの弾性に抗し、つまり板ばねに弾性力ないは付勢力を蓄えつつ回転して被係脱部材を係止解除する。係合体は、その係止解除状態から板ばねに蓄えられた付勢力により再び係止状態に切り換えられる。
In the present invention, in a locked state in which the engaging body locks the engaged / disengaged member (the trace member is locked in the cam groove), a load of a certain value or more is received in the forcibly removing direction via the engaged / disengaged member. When the engagement body tries to rotate in the unlocking direction, it resists the elasticity of the leaf spring, that is, the leaf spring does not have an elastic force or rotates while accumulating an urging force to unlock the engaged / disengaged member. . The engaging body is switched from the unlocked state to the locked state again by the urging force stored in the leaf spring.
換言すると、本発明において、ケース内の板ばねは係合体が係止解除方向に回転する毎に撓んで付勢力を蓄積し、係止解除時は蓄積された付勢力により係合体を再び係止状態に切り換える。構造特徴は、板ばねの撓み力を利用しているため、簡易であり、かつ高強度を得られる。また、無理抜きを伴わない通常の作動は、板ばねが撓まないため、板ばねがない構造と同様に良好に維持される。しかも、無理抜き荷重ないしは強度が板ばねの板金強度に依存するため、無理抜き荷重を高くしたり、多数の強度バリエーションを展開可能であり、その結果、設計自由度を向上し用途拡大に寄与できる。
In other words, in the present invention, the leaf spring in the case bends each time the engaging body rotates in the unlocking direction and accumulates the urging force, and when the locking is released, the engaging body is locked again by the accumulated urging force. Switch to state. The structural feature is simple and high strength can be obtained because the bending force of the leaf spring is used. Moreover, since the leaf | plate spring does not bend, the normal operation | movement without forcibly removing is maintained favorable similarly to the structure without a leaf | plate spring. In addition, the force of unloading or the strength depends on the strength of the leaf spring, so the force of unloading can be increased or a number of strength variations can be developed. As a result, the degree of freedom in design can be improved and the application can be expanded. .

More specifically, the leaf spring 6 is placed on the both sides of the flat plate main plate portion 6a which is located at the center and forms the guide groove 6f, and on the both sides of the rear plate portion from the main plate portion 6a. 13 is provided with an attachment locking portion 6b (see FIG. 1 (b)) to be mounted by a clamping structure, a cutout portion 6g formed in the front plate portion from the main plate portion 6a, and a cutout portion 6. Abutting portions 6c that rise obliquely from the front portion and contact the protrusion 33 of the engaging body 3 and are erected on both sides of the main plate portion 6a and are attached to both inner side surfaces of the case by pressure contact and engagement structures. It has a locking portion 6e for both positioning and attachment, and a guide groove 6f that is formed through the main plate portion 6a to restrict the range of movement of the sliding body 2 in the front-rear direction.
(組立)以上の各部材は、まず、係合体3が摺動体2に枢支されると共に、板ばね6がケース1に取り付けられる。この作業において、係合体3は、摺動体2に対し筒部26を両後片部31同士の間に配置し、軸孔29と軸孔34とを同軸線上に位置だし、その状態で、シャフト39を一方軸孔34、軸孔29、他方軸孔34に挿入すると、所定角度だけ回転可能に枢支される。板ばね6は、ケース1の内底面側に対し、後両側の係止部6bが底壁13に挟着され、略中間両側の係止部6eがケース対応部に位置決めされた状態に圧着される。これにより、板ばね6は、図5(a),(b)のごとくメイン板部6aを含む後側がケース1の内底面に装着され、メイン板部6aより前側がケース内面から浮いた状態に配置される。
(Assembly) In each of the above members, first, the engaging body 3 is pivotally supported by the sliding body 2 and the leaf spring 6 is attached to the case 1. In this operation, the engaging body 3 is configured such that the cylindrical portion 26 is disposed between the rear piece portions 31 with respect to the sliding body 2 and the shaft hole 29 and the shaft hole 34 are positioned on the coaxial line. When 39 is inserted into the one shaft hole 34, the shaft hole 29, and the other shaft hole 34, it is pivotally supported by a predetermined angle. The leaf spring 6 is crimped to the inner bottom surface side of the case 1 in such a manner that the engaging portions 6b on both rear sides are sandwiched by the bottom wall 13 and the engaging portions 6e on both substantially intermediate sides are positioned on the case corresponding portions. The Thus, the leaf spring 6 is mounted on the inner bottom surface of the case 1 at the rear side including the main plate portion 6a as shown in FIGS. 5A and 5B, and the front side from the main plate portion 6a is lifted from the inner surface of the case. Be placed.
次に、ケース1に対して以上の係合体3付きの摺動体2が組み込まれる。この作業では、例えば、予めばね部材4が支持軸40を介して、また、トレース部材5が上記した底壁13の保持部に揺動可能に支持した状態にしてそれぞれケース1内に配置しておく。そして、係合体3付きの摺動体2は、突起20aをガイド溝10aに、突起20bをガイド溝14にそれぞれ嵌合した状態で、ケース1内に押し入れられると、突起26aが板ばね側ガイド溝6fに落ち込んで嵌合されたときに、ケース1に対し抜け止めされて組み付けられる。
Next, the sliding body 2 with the above engaging body 3 is incorporated into the case 1. In this operation, for example, the spring member 4 is arranged in the case 1 in advance in a state where the spring member 4 is supported in a swingable manner on the holding portion of the bottom wall 13 described above via the support shaft 40. deep. When the sliding body 2 with the engaging body 3 is pushed into the case 1 with the projection 20a fitted into the guide groove 10a and the projection 20b fitted into the guide groove 14, the projection 26a is moved to the leaf spring side guide groove. When it is lowered into 6f and fitted, it is secured to the case 1 and assembled.
この押し入れ過程では、ばね部材4の上側が筒部26内に入り、係合体3の前板部30の端面側に当接する。そして、ばね部材4は、摺動体2がケース1の奥へ押圧移動される過程で付勢力を増大し、該付勢力によって係合体3をシャフト39を支点として係止状態の方向へ回転可能にする。また、トレース部材のピン部5cは、対応するカム溝27の溝入口に入る。一方、板ばね側当接部6cは、図7(a),(b)のごとくストライカー7の引き抜き方向への引き力により係合体3が係止解除方向へ揺動されるときにその係合体3の揺動抵抗となって付勢力を蓄え、かつ、図8(a),(b)のごとくストライカー7を係合体3から引き抜くと蓄えた付勢力により係合体3を再び係止状態に切り換える。
In this pushing-in process, the upper side of the spring member 4 enters the cylindrical portion 26 and comes into contact with the end face side of the front plate portion 30 of the engaging body 3. The spring member 4 increases the urging force in the process in which the sliding body 2 is pressed and moved to the back of the case 1, and the urging force allows the engaging body 3 to rotate in the locked state with the shaft 39 as a fulcrum. To do. Further, the pin portion 5 c of the trace member enters the groove entrance of the corresponding cam groove 27. On the other hand, the leaf spring side contact portion 6c is engaged when the engaging body 3 is swung in the unlocking direction by the pulling force in the pulling direction of the striker 7 as shown in FIGS. 7 (a) and 7 (b). When the striker 7 is pulled out from the engagement body 3 as shown in FIGS. 8A and 8B, the engagement body 3 is again switched to the locked state by the stored biasing force. .
(作動)以上のラッチ装置は、使用態様として、図4(a),(b)に例示したごとく扉9に取り付けられたストライカー7に対応して、機器類側本体8に位置決めされてねじなどにより取り付けられる。取付状態において、ラッチ装置は、通常、図5(a),(b)のごとく摺動体2がばね部材4により突出方向へ付勢移動(この移動は突起26aがガイド溝11fの前端面に当たることで規制される)されると共に、係合体3が爪部32を本体内部24から外へ退行する方向へ回転(この回転は凸部36が張出部16の最も高くなった箇所に乗り上げる)されている。この状態が係合体3の係止解除状態である。
(Operation) The above-described latch device is used as a usage mode, as shown in FIGS. 4 (a) and 4 (b), corresponding to the striker 7 attached to the door 9, and positioned on the equipment-side main body 8 to be a screw or the like. It is attached by. In the mounted state, the latch device normally moves the sliding body 2 in the protruding direction by the spring member 4 as shown in FIGS. 5A and 5B (this movement is such that the protrusion 26a hits the front end face of the guide groove 11f. And the engaging body 3 is rotated in a direction in which the claw portion 32 retracts outward from the inside 24 of the main body (this rotation rides on the highest point of the protruding portion 16). ing. This state is the unlocking state of the engagement body 3.
扉9が閉方向である図4(a)の左矢印方向に押し操作されると、摺動体2はストライカー7によりばね部材4の付勢力に抗してケース1内に没する方向へ押圧移動される。その移動過程では係合体3がシャフト39を支点として係止状態の方向へ回転される。すると、係合体3は、凸部35が張出部16の低い側へ移行し、同時にストライカーの先端7aの手前に設けられた凹部7cに爪部32を係合し抜け止めする。このとき、係合体3は、図6(a),(b)のごとくトレース部材のピン部5cが摺動体2及び係合体3の後方移動によって上記した誘導溝27aから係止用誘導溝27bに入り、図5(a),(b)の左矢印方向の押圧力を解放したときに、係止溝27cに係止される。この係止により、扉9が閉状態にロック保持される。
When the door 9 is pushed in the direction of the left arrow in FIG. 4A, which is the closing direction, the sliding body 2 is pushed and moved by the striker 7 in a direction in which the sliding body 2 is submerged in the case 1 against the urging force of the spring member 4. Is done. In the moving process, the engaging body 3 is rotated in the direction of the locked state with the shaft 39 as a fulcrum. Then, in the engaging body 3, the convex portion 35 moves to the lower side of the overhang portion 16, and at the same time, the claw portion 32 is engaged with the concave portion 7c provided in front of the tip 7a of the striker to prevent it from coming off. At this time, as shown in FIGS. 6 (a) and 6 (b), the engaging member 3 is moved from the guide groove 27a to the locking guide groove 27b by the rearward movement of the sliding member 2 and the engaging member 3 by the pin portion 5c of the trace member. When the pressing force in the direction of the left arrow in FIGS. 5 (a) and 5 (b) is released, it is locked in the locking groove 27c. By this engagement, the door 9 is locked and held in the closed state.
また、以上の扉保持状態から図5(a),(b)の解除状態に切り換えるときは、扉9を閉じ方向へ少し押した後、該押し力を解放する。すると、トレース部材のピン部5cは、図6(b)のごとく上記した係止溝27cから解除用誘導溝27d、復帰溝27eを経て再び溝入口に戻り、同時に、係合体3が当初の解除位置に切り換えられる。このラッチ装置は、以上のような通常の作動において従来と同様であるが、次の点で改良されている。
Also, when switching from the above-mentioned door holding state to the released state shown in FIGS. 5A and 5B, the pushing force is released after the door 9 is pushed slightly in the closing direction. Then, the pin portion 5c of the trace member returns to the groove entrance again from the locking groove 27c described above through the release guiding groove 27d and the return groove 27e as shown in FIG. 6B, and at the same time, the engaging body 3 is released from the initial state. Switch to position. This latch device is the same as the conventional one in the normal operation as described above, but is improved in the following points.
すなわち、以上のラッチ装置では、通常時の作動を従来と同様に維持しながら、無理抜き荷重、つまり係合体3の係止状態において、上記した扉9に対し扉開方向に外力が作用したとき、図7(a)のごとく係合体3が爪部32を本体内部24から外へ退行するよう回転、つまり無理抜きにより係止解除状態に切り換えられる際の荷重ないしは強度を板ばね6によって高めることができ、更には板ばね6として当接部6c及び当接部6cとメイン板部6aとの間の板部の幅、傾き、長さなどによって変形度合いを変えるだけで、用途に応じた最適な無理抜き荷重に変更できる。この点を図7(a),(b)と図8(a),(b)を参照して明らかにする。
That is, in the latch device described above, when an external force is applied to the door 9 in the door opening direction in the forced release load, that is, in the locked state of the engaging body 3 while maintaining the normal operation as in the conventional case. As shown in FIG. 7A, the load or strength is increased by the leaf spring 6 when the engaging body 3 is rotated so as to retract the claw portion 32 from the inside 24 of the main body, that is, when the engaging body 3 is switched to the unlocked state by forcibly removing. In addition, the plate spring 6 can be optimized according to the application by simply changing the degree of deformation according to the contact portion 6c and the width, inclination, length, etc. of the plate portion between the contact portion 6c and the main plate portion 6a. It can be changed to an unreasonable unloading load. This point will be clarified with reference to FIGS. 7A and 7B and FIGS. 8A and 8B.
図7(a),(b)は図6(a)のごとく係合体3の係止状態において、上記した扉9に対し扉開方向である図7(a)の矢印方向に外力が作用した態様を示している。この態様では、係合体3が外力により前方へ引っ張られると、シャフト39を支点として時計回りの方向へ動こうとする。その際、係合体3は、爪部32が開口21aの対応部に摺接しながら、本体内部24から退行、つまり板ばね側当接部6cに対する圧接度合いを強めて係止解除方向へ回転する。当接部6cにはその圧接により付勢力が蓄積される。
7 (a) and 7 (b), when the engagement body 3 is locked as shown in FIG. 6 (a), an external force is applied to the door 9 in the arrow direction of FIG. 7 (a), which is the door opening direction. An embodiment is shown. In this embodiment, when the engagement body 3 is pulled forward by an external force, the engagement body 3 tends to move in the clockwise direction with the shaft 39 as a fulcrum. At this time, the engaging body 3 rotates in the unlocking direction with the degree of pressure contact with the leaf spring side contact portion 6c intensified by retreating from the inside of the main body 24 while the claw portion 32 is in sliding contact with the corresponding portion of the opening 21a. The urging force is accumulated in the contact portion 6c by the pressure contact.
以上のような付勢力の蓄積は、係合体3が図7(a)のごとく係止解除状態に達し、ストライカー7の先端7aが開口21aを横切って外へ移動される直前で最大となる。すなわち、この構造では、係合体3がシャフト39を支点とし係止状態から係止解除状態に回転して切り換えられるときに、板ばね側当接部6cの変形抵抗を受けることにより課題に記載した無理抜き荷重ないしは強度を高くすることができる。この無理抜き荷重ないしは強度は、例えば、当接部6cやその付近の板部の幅などを変えることにより、用途に応じた任意の大きさに簡単に変更できる。
Accumulation of the urging force as described above is maximized immediately before the engagement body 3 reaches the unlocked state as shown in FIG. 7A and the tip 7a of the striker 7 is moved outward across the opening 21a. That is, in this structure, when the engagement body 3 is rotated and switched from the locked state to the unlocked state with the shaft 39 as a fulcrum, the deformation resistance of the leaf spring side contact portion 6c is received and described in the problem. Unreasonable load or strength can be increased. This unreasonable load or strength can be easily changed to an arbitrary size according to the application, for example, by changing the width of the contact portion 6c or the plate portion in the vicinity thereof.
図8(a),(b)は図7(a),(b)のごとく無理抜きした後のラッチ装置を再び使用するときの操作例を示している。つまり、図8(a)のラッチ装置は、図6(a)の態様からストライカー7を省いた状態であり、トレース部材のピン部5cがカム溝の係止溝27cに係止されている。このため、使用者は、指などによりケース1から突出している摺動体の本体部分を図8(a)の矢印方向に一旦押して離す。すると、上記したごとくトレース部材のピン部5cは図8(b)のごとく係止溝27cから解除用誘導溝27d、復帰溝27eを経て溝入口に戻り、同時に、係合体3は図5(a),(b)の解除状態に切り換えられる。これにより、ラッチ装置は再び通常使用時の初期態様に切り換えられる。
8 (a) and 8 (b) show an example of operation when the latch device is used again after being forcibly removed as shown in FIGS. 7 (a) and 7 (b). That is, the latch device of FIG. 8A is in a state where the striker 7 is omitted from the embodiment of FIG. 6A, and the pin portion 5c of the trace member is locked to the locking groove 27c of the cam groove. For this reason, the user once pushes and releases the main body portion of the sliding body protruding from the case 1 with a finger or the like in the direction of the arrow in FIG. Then, as described above, the pin portion 5c of the trace member returns from the locking groove 27c to the groove entrance through the release guide groove 27d and the return groove 27e as shown in FIG. ), (B). As a result, the latch device is again switched to the initial state during normal use.
