Description

本発明は、開き窓などの建具における建具体を建具枠に施錠するのに用いられるラッチ装置、及びそのラッチ装置を備えた建具に関する。   The present invention relates to a latch device that is used to lock a building concrete in a fitting such as a casement window to a fitting frame, and a fitting including the latch device.

建具としては、内倒し窓、外倒し窓などのように、窓枠に障子を開閉自在に取付けた開き窓が知られている。
かかる開き窓においては、障子にラッチ装置を取付け、その障子を閉じ状態でラッチ装置によって施錠することが行われている。
前述のラッチ装置としては特許文献１に開示されたものが知られている。
このラッチ装置は、外筐と蓋板に沿ってラッチを施錠位置と解錠位置とに亘って移動自在に設け、このラッチをばねで施錠位置に向けて付勢して保持すると共に、このラッチを外力及び操作杆によってばねに抗して解錠位置に移動できるようにしてある。
前述のラッチ装置は、その外筐を障子に取付け、その障子を閉じ位置に向かう方向に移動すると、ラッチが窓枠の係止部に接してばねに抗して解錠位置に移動し、その障子が閉じ位置となるとラッチが窓枠の係止部を越えてばねで施錠位置となり、そのラッチが窓枠の係止部に係止して障子を施錠し、操作杆によってラッチをばねに抗して解錠位置に移動することで解錠して障子を開放できるようにする。 As a joinery, there is known an open window in which a shoji is attached to a window frame so as to be freely opened and closed, such as an interior fall window and an outside fall window.
In such an opening window, a latch device is attached to a shoji, and the shoji is closed and locked by the latch device.
As the aforementioned latch device, the one disclosed in Patent Document 1 is known.
The latch device is provided with a latch movably between a locking position and an unlocking position along the outer casing and the cover plate, and the latch is urged and held toward the locking position by a spring. Can be moved to the unlocked position against the spring by external force and operating rod.
In the latch device described above, when the outer casing is attached to the shoji and the shoji is moved in the direction toward the closing position, the latch contacts the latching portion of the window frame and moves to the unlocking position against the spring. When the shoji is in the closed position, the latch goes over the locking part of the window frame and is locked by the spring, and the latch locks to the latching part of the window frame to lock the shoji. Then, by moving to the unlocking position, the shoji can be unlocked and opened.

実公昭５８−２９２３８号公報Japanese Utility Model Publication No. 58-29238

前述したラッチ装置は、そのラッチと操作杆が施錠位置に向かう方向、解錠位置に向かう方向にそれぞれ連動して動く。つまり、ラッチが施錠位置に向かう方向に動くと操作杆も施錠位置に向かう方向に動き、ラッチが解錠位置に向かう方向に動くと操作杆も解錠位置に向かう方向に動く。操作杆が施錠位置に向かう方向に動くとラッチも施錠位置に向かう方向に動き、操作杆が解錠位置に向かう方向に動くとラッチも解錠位置に向かう方向に動く。   The above-described latch device moves in conjunction with the direction in which the latch and the operating rod move toward the locking position and the direction toward the unlocking position. That is, when the latch moves in the direction toward the locking position, the operation rod moves in the direction toward the locking position, and when the latch moves in the direction toward the unlocking position, the operation rod also moves in the direction toward the unlocking position. When the operating rod moves in the direction toward the locking position, the latch also moves in the direction toward the locking position, and when the operating rod moves in the direction toward the unlocking position, the latch also moves in the direction toward the unlocking position.

このようであるから、施錠位置のラッチが解錠位置に向けて動く時には操作杆も同時に解錠位置に向けて動くことになるので、その操作杆を外筐、蓋体に接して動かないように支持した状態では、施錠位置のラッチを解錠位置に移動できない。
したがって、操作杆を外筐、蓋体に接し、その操作杆によって障子を閉じ操作した時には、その操作杆が解錠位置に向かう方向に動くことがないから、ラッチが解錠位置に向かう方向に動くことができず、そのラッチが窓枠の係止部に接した時に施錠位置のままとなるので、障子を閉じることができないことがある。 Because of this, when the latch at the locking position moves toward the unlocking position, the operating rod also moves toward the unlocking position at the same time, so that the operating rod does not move in contact with the outer casing and lid. In the state where it is supported, the latch at the lock position cannot be moved to the unlock position.
Therefore, when the operating rod is in contact with the outer casing and the lid, and the shoji is closed with the operating rod, the operating rod does not move in the direction toward the unlocking position, so the latch moves in the direction toward the unlocking position. Since it cannot move and remains in the locked position when its latch contacts the locking part of the window frame, it may not be possible to close the shoji.

例えば、排煙窓などの高い場所に取付けた開き窓においては、長いロッドなどの操作棒を用いてラッチ装置の操作杆を操作して障子を開閉することがある。
具体的には、開放している窓を閉じるには、障子に取付けたラッチ装置の操作杆を操作棒で押して外筐、蓋体に接し、その外筐、蓋体とともに障子を閉じ位置に向けて移動することになるが、このようにするとラッチ装置の操作杆が操作棒によって解錠位置に向けて動くことができないので、ラッチが窓枠の係止部に押しつけられても解錠位置に向けて動くことができず、そのラッチが窓枠の係止部に押しつけられたままとなり、障子を閉じ位置まで動かすことができないから、前述したラッチ装置を取付けた開き窓においては、操作棒を用いてラッチ装置のラッチを操作して障子を閉じることができない。 For example, in a case of an opening window attached to a high place such as a smoke exhaust window, a shoji may be opened and closed by operating an operating rod of a latch device using an operating rod such as a long rod.
Specifically, in order to close the open window, the operating rod of the latch device attached to the shoji is pushed with the operating rod to contact the outer casing and the lid, and the shoji together with the outer casing and the lid is directed to the closed position. In this way, the operating rod of the latch device cannot be moved toward the unlocking position by the operating rod, so even if the latch is pressed against the locking part of the window frame, it will be in the unlocking position. The latch cannot be moved to the closed position because the latch remains pressed against the locking portion of the window frame. It cannot be used to operate the latch of the latch device to close the shoji.

本発明の目的は、操作杆をケースに接して動かないように支持した状態で、施錠位置のラッチを外力で解錠位置に移動でき、その操作杆によって建具体をスムーズに閉じ操作できるようにしたラッチ装置及び、そのラッチ装置を用いた建具とすることである。   The object of the present invention is to enable the latch of the locking position to be moved to the unlocking position by an external force with the operation rod supported so as not to move in contact with the case, so that the construction can be smoothly closed by the operation rod. And a fitting using the latch device.

前記ラッチが施錠位置の時にはアーム部の取付部よりも操作部寄り部分がラッチの操作杆当接部に接して操作杆は第１の位置に保持され、
前記操作杆が、この第１の位置からラッチ解錠方向に揺動した第２の位置の時にはアーム部の取付部よりも操作部寄り部分で操作杆当接部を押してラッチが弾性部材に抗して解錠位置に移動し、
前記操作杆が、そのアーム部が前記ケースに接してラッチ施錠方向には揺動しないように支持した第３の位置のときには、アーム部とラッチ部下面との間の間隔がラッチの施錠位置から解錠位置までの移動距離よりも広く、施錠位置のラッチが解錠位置まで移動可能とし、
前記ラッチの操作杆当接部は円弧形状で、操作杆を第１の位置から第２の位置に揺動する際に、その操作杆のアーム部の取付部よりも操作部寄り部分と操作杆当接部との接する位置が、アーム部の長手方向に順次移動するようにしたことを特徴とするラッチ装置である。 The latch device according to the present invention includes a case attached to a specific construction of a joinery , a latch provided on the case so as to be movable between a locked position and an unlocked position, and an elastic force that holds the latch in a locked position. A member and an operating rod attached to the case so as to be swingable in the latch releasing direction and the latch locking direction along the latch moving direction;
The case has a latch support portion and an operation rod insertion portion,
The latch includes a latch portion, an operation rod insertion portion, and an operation rod contact portion, and the latch support portion of the case includes a locking position where the latch portion engages with a concrete-specific engagement portion of the joinery, and the latch The latch part is supported movably across the unlocking position away from the locking part,
The operating rod has an arm portion and an operating portion, and the arm portion passes through the operating rod insertion portion of the case and the operating rod insertion portion of the latch into the case in the latch unlocking direction and the latch locking direction. Mounted so that it can swing freely, the operation part protrudes from the case,
When the latch is in the locked position, the portion closer to the operation portion than the attachment portion of the arm portion is in contact with the operation rod contact portion of the latch, and the operation rod is held at the first position.
When the operating rod is in the second position swinging in the latch unlocking direction from the first position, the operating rod contact portion is pushed closer to the operating portion than the mounting portion of the arm portion, so that the latch resists the elastic member. Move to the unlocked position,
When the operating rod is in the third position where the arm portion is in contact with the case and supported so as not to swing in the latch locking direction, the distance between the arm portion and the lower surface of the latch portion is from the locking position of the latch. It is wider than the moving distance to the unlocking position, and the locking position latch can move to the unlocking position,
The operating rod contact portion of the latch has an arc shape, and when the operating rod is swung from the first position to the second position, a portion closer to the operating portion than the mounting portion of the arm portion of the operating rod and the operating rod The latch device is characterized in that the position in contact with the contact portion is sequentially moved in the longitudinal direction of the arm portion.

本発明のラッチ装置を備えた建具は、建具枠に建具体を開閉自在に取付け、この建具体に、前述の本発明のラッチ装置におけるケースを取付け、
このラッチ装置のラッチが施錠位置の時に建具枠の係止部に係止して建具体を施錠するようにしたことを特徴とするラッチ装置を備えた建具である。 The joinery provided with the latch device of the present invention is attached to the joinery frame so as to be openable and closable.
When the latch of the latch device is in the locking position, the latch is locked to the locking portion of the joinery frame to lock the building details.

本発明のラッチ装置によれば、操作杆をケースに接した第３の位置でラッチ施錠方向に揺動しないように支持した状態で、施錠位置のラッチを外力によって解錠位置に移動できる。
したがって、建具の建具体にラッチ装置のケースを取付けることで、そのラッチ装置の操作杆を第３の位置として建具体を閉じ操作することで、ラッチのラッチ部が建具枠の係止部に押しつけられて外力が作用することでラッチが解錠位置に移動するので、操作杆によって建具をスムーズに閉じ操作できる。
また、ケースのラッチ支承部に沿ってラッチをスムーズに施錠位置と解錠位置に移動できる。
また、操作杆を第２の位置とすることで、そのアーム部の取付部よりも操作部寄り部分が操作杆当接部に接してラッチを解錠位置に移動する。
また、操作杆が第３の位置の時にラッチを解錠位置に移動しても、そのラッチ部下面が操作杆のアーム部に接することがなく、操作杆を第３の位置で動かさないように支持した状態でラッチを解錠位置に移動できる。
また、操作杆を第１の位置から第２の位置に揺動して施錠位置のラッチを解錠位置に移動する時に、操作杆のアーム部の取付部よりも操作部寄り部分とラッチの操作杆当接部との接する位置がアーム部の長手方向に順次移動するから、１点に集中して負荷が作用しないので、アーム部と操作杆当接部の接する部分が異常摩耗等することがない。
According to the latch device of the present invention, the latch at the locking position can be moved to the unlocking position by an external force in a state where the operating rod is supported so as not to swing in the latch locking direction at the third position in contact with the case.
Therefore, by attaching the case of the latch device to the construction material of the joinery, and closing the construction material with the operating rod of the latch device as the third position, the latch portion of the latch is pressed against the locking portion of the joinery frame. Since the latch is moved to the unlocked position when an external force is applied, the fitting can be smoothly closed with the operation rod.
Further, the latch can be smoothly moved to the locked position and the unlocked position along the latch support portion of the case.
Further, by setting the operating rod to the second position, the portion closer to the operating portion than the mounting portion of the arm portion comes into contact with the operating rod contact portion, and the latch is moved to the unlocked position.
Further, even if the latch is moved to the unlocked position when the operating rod is in the third position, the lower surface of the latch portion does not come into contact with the arm portion of the operating rod so that the operating rod does not move in the third position. The latch can be moved to the unlocked position while being supported.
Further, when the operating rod is swung from the first position to the second position and the latch at the locking position is moved to the unlocking position, the operation portion closer to the operating portion and the latch are operated than the mounting portion of the arm portion of the operating rod. Since the position in contact with the heel contact portion sequentially moves in the longitudinal direction of the arm portion, the load does not act concentrated on one point, so the portion where the arm portion and the operation heel contact portion contact may be abnormally worn. Absent.

本発明のラッチ装置を備えた建具によれば、操作杆を操作棒などで押して第３の位置とし、さらに操作棒によって建具体を閉じ操作することで、操作杆、ケースを介して建具体が閉じ位置に向けて動き、そのラッチが建具枠の係止部に押しつけられることによって、そのラッチは弾性部材に抗して解錠位置に移動するので、ラッチ装置の操作杆を操作することで建具体をスムーズに閉じ操作できる。   According to the joinery provided with the latch device of the present invention, the operation rod is pushed to the third position by the operation rod or the like, and further, the building concrete is closed by the operation rod, so that the construction concrete can be obtained through the operation rod and the case. By moving toward the closed position and pressing the latch against the locking part of the joinery frame, the latch moves to the unlocked position against the elastic member. It can be closed smoothly.

図１に示すように、建具枠１に建具体２を開閉自在に取付けて建具としてある。
この建具体２に、その建具体２を閉じ状態で施錠するラッチ装置３が取付けてある。
図１に示す実施の形態では、建具枠１は上枠１０と下枠１１と左右の縦枠１２を方形状に連結した窓枠である。
前記建具体２は上框２０と下框２１と左右の縦框２２を方形状に連結し、その内部にガラス等のパネル２３を装着した障子である。
そして、下枠１１と下框２１がヒンジ４で室内方向に揺動自在に連結された内倒し窓としてある。
前記ラッチ装置３は上框２０の室内側面２０ａに取付けてある。このラッチ装置３が上枠１０の係止部、例えば受け金具１３に係脱自在である。 As shown in FIG. 1, a building concrete 2 is attached to a fitting frame 1 so as to be freely opened and closed.
A latch device 3 for locking the building concrete 2 in the closed state is attached to the building concrete 2.
In the embodiment shown in FIG. 1, the joinery frame 1 is a window frame in which an upper frame 10, a lower frame 11, and left and right vertical frames 12 are connected in a square shape.
The construction concrete 2 is a shoji which has an upper fence 20, a lower fence 21, and left and right vertical fences 22 connected in a square shape and a panel 23 made of glass or the like mounted therein.
The lower frame 11 and the lower collar 21 serve as an inward window in which the hinge 4 is pivotably connected in the indoor direction.
The latch device 3 is attached to the indoor side surface 20a of the upper collar 20. The latch device 3 can be freely engaged with and disengaged from a locking portion of the upper frame 10, for example, a receiving metal 13.

前記ラッチ装置３は図２に示すように、ケース３０とラッチ４０と操作杆５０と弾性部材６０を備えている。
前記ラッチ４０はケース３０に図２に示す施錠位置と図３に示す解錠位置とに亘って移動自在に設けてあり、このラッチ４０は前述の弾性部材６０で図２に示すように受け金具１３に係止する施錠位置に向けて付勢して保持してある。
前記操作杆５０はケース３０に、ラッチ４０の移動方向に揺動自在に取付けてある。この操作杆５０は図２に示すようにラッチ４０が施錠位置の時には第１の位置に保持される。この第１の位置の操作杆５０をラッチ解錠方向に揺動して図３に示す第２の位置とすると、前記ラッチ４０は弾性部材６０に抗して受け金具１３と離脱する解錠位置に移動する。 As shown in FIG. 2, the latch device 3 includes a case 30, a latch 40, an operating rod 50, and an elastic member 60.
The latch 40 is provided on the case 30 so as to be movable between a locked position shown in FIG. 2 and an unlocked position shown in FIG. 3, and the latch 40 is a receiving metal fitting as shown in FIG. It is urged and held toward the locking position where it is locked to 13.
The operating rod 50 is attached to the case 30 so as to be swingable in the moving direction of the latch 40. As shown in FIG. 2, the operating rod 50 is held in the first position when the latch 40 is in the locked position. When the operating rod 50 at the first position is swung in the latch unlocking direction to the second position shown in FIG. 3, the latch 40 is unlocked from the receiving member 13 against the elastic member 60. Move to.

図２に示す状態は、その操作杆５０がケース３０に接した第３の位置となっている。その第３の位置で動かないように操作杆５０が支持された状態で、ラッチ４０を外力により押すことで、ラッチ４０は弾性部材６０に抗して図４に示すように受け金具１３と離脱する解錠位置まで移動する。   In the state shown in FIG. 2, the operating rod 50 is in the third position in contact with the case 30. When the operating rod 50 is supported so that it does not move at the third position, the latch 40 is pushed by an external force, so that the latch 40 is separated from the receiving metal 13 as shown in FIG. Move to the unlocking position.

このようであるから、操作杆５０を第３の位置で動かないように支持した状態で、施錠位置のラッチ４０を外力で解錠位置までスムーズに移動でき、その操作杆５０によって建具体２をスムーズに閉じ操作できる。
例えば、図１に示す内倒し窓の場合に、仮想線で示すように開放している障子（建具体２）をロッドなどの操作棒５でラッチ装置３の操作杆５０をラッチ施錠方向（矢印ａ）に押して閉じ操作すると、操作杆５０がケース３０に接した第３の位置で動かないように支持され、操作杆５０、ケース３０を経て障子が閉じ方向に回動し、図５に示すように、ラッチ４０が上枠１０に固着した受け金具１３に押しつけられる。
この状態から障子を、さらに徒事方向に回動することによって、ラッチ４０には押し下げの外力が作用し、そのラッチ４０は弾性部材６０に抗して解錠位置に向けて移動する。
そして、ラッチ４０が受け金具１３を越えたらラッチ４０が図２に示すように弾性部材６０で施錠位置に移動することで、図１に実線で示すように障子（建具体２）を窓枠（建具枠１）に施錠する。 Thus, in a state where the operating rod 50 is supported so as not to move at the third position, the latch 40 at the locking position can be smoothly moved to the unlocked position by an external force. It can be closed smoothly.
For example, in the case of the inward window shown in FIG. 1, the shoji (construction concrete 2) opened as shown by the phantom line is latched with the operating rod 5 such as a rod and the operating rod 50 of the latch device 3 is latched in the locking direction (arrow When the closing operation is performed by pushing to a), the operation rod 50 is supported so as not to move at the third position in contact with the case 30, and the shoji is rotated in the closing direction through the operation rod 50 and the case 30, as shown in FIG. As described above, the latch 40 is pressed against the receiving metal 13 fixed to the upper frame 10.
When the shoji is further rotated in this direction from this state, an external force is applied to the latch 40, and the latch 40 moves toward the unlocked position against the elastic member 60.
Then, when the latch 40 exceeds the receiving metal 13, the latch 40 is moved to the locking position by the elastic member 60 as shown in FIG. 2, so that the shoji (construction concrete 2) is moved to the window frame (construction concrete 2) as shown by the solid line in FIG. Lock the joinery frame 1).

図１に実線で示す状態から障子を開放するには、操作杆５０を操作棒５で下方（矢印ｂ）に引張り、操作杆５０を第２の位置としてラッチ４０を図３に示すように解錠位置まで移動する。
これによって、ラッチ４０が受け金具１３から離脱して解錠状態となるので、障子を室内側に傾倒して仮想線で示すように開放する。 To release the shoji from the state shown by the solid line in FIG. 1, pull the operating rod 50 downward (arrow b) with the operating rod 5, and the latch 40 is opened as shown in FIG. Move to the lock position.
As a result, the latch 40 is detached from the metal fitting 13 and is unlocked, so that the shoji is tilted indoors and opened as indicated by a virtual line.

この実施の形態では、ラッチ４０は樹脂製のラッチ本体４１と、金属製のスライダー４２を備え、このスライダー４２にラッチ本体４１を嵌め込んでラッチ４０としてある。
前記ラッチ本体４１は、ラッチ移動方向中間に空洞部４３を有し、この空洞部４３はラッチ移動方向と直角方向の両面に開口して前述の操作杆挿通部４０ｂとなり、前述の円弧状面４０ｄと下面４０ｆと操作杆当接部４０ｃを有している。
前記スライダー４２は、基板４２ａと両側板４２ｂでコ字形状で、その基板４２ａに開口窓４４と支持片４５が設けてある。
そして、スライダー４２にラッチ本体４１を嵌め込んで連結することで、開口窓４４と空洞部４３が連通して前述の操作杆挿通部４０ｂとなる。
ラッチ本体４１の下部がスライダー４２の支持片４５に接してラッチ本体４１とスライダー４２がラッチ移動方向に抜けないように強固に連結している。
なお、図示は省略するがラッチ本体４１に突起を設け、スライダー４２には突起が嵌合する穴を形成し、その突起と穴が嵌合することでラッチ本体４１とスライダー４２をより強固に連結しても良い。 In this embodiment, the latch 40 includes a resin latch body 41 and a metal slider 42, and the latch body 41 is fitted into the slider 42 to form the latch 40.
The latch body 41 has a hollow portion 43 in the middle of the latch movement direction, and the hollow portion 43 opens on both sides in a direction perpendicular to the latch movement direction to form the operation rod insertion portion 40b, and the arcuate surface 40d. And a lower surface 40f and an operating rod contact portion 40c.
The slider 42 is U-shaped with a substrate 42a and both side plates 42b, and an opening window 44 and a support piece 45 are provided on the substrate 42a.
Then, the latch main body 41 is fitted and connected to the slider 42, whereby the opening window 44 and the cavity 43 communicate with each other to form the operation rod insertion portion 40b described above.
The lower portion of the latch body 41 is in contact with the support piece 45 of the slider 42 and is firmly connected so that the latch body 41 and the slider 42 do not come out in the latch moving direction.
Although not shown, the latch body 41 is provided with a protrusion, the slider 42 is formed with a hole in which the protrusion is fitted, and the protrusion and the hole are fitted to connect the latch body 41 and the slider 42 more firmly. You may do it.

前記操作杆５０はアーム部５１とリング状の操作部５２を備えている。このアーム部５１にピン挿通孔５３が形成してある。
このアーム部５１がアウトケース３１の開口部３５（ケース３０の操作杆挿通部３４）、スライダー４２の開口窓４４を挿通してラッチ本体４１の空洞部４３（ラッチ４０の操作杆挿通部４０ｂ）に挿通し、前記アウトケース３１のピン挿通孔３６、インナーケース３２のピン挿通孔３８及びアーム部５１のピン挿通孔５３にピン５４を挿通し、アーム部５１をケース３０に揺動自在に取付ける。 The operation rod 50 includes an arm portion 51 and a ring-shaped operation portion 52. A pin insertion hole 53 is formed in the arm portion 51.
The arm portion 51 is inserted through the opening 35 of the outcase 31 (the operation rod insertion portion 34 of the case 30) and the opening window 44 of the slider 42, and the cavity portion 43 (the operation rod insertion portion 40b of the latch 40) of the latch body 41. The pin 54 is inserted into the pin insertion hole 36 of the outcase 31, the pin insertion hole 38 of the inner case 32, and the pin insertion hole 53 of the arm portion 51, and the arm portion 51 is swingably attached to the case 30. .

これによって、ラッチ４０が施錠位置の時にアーム部５１がラッチ４０の操作杆当接部４０ｃに接して第１の位置に保持される。そして操作杆５０をラッチ解錠方向に揺動して第２の位置とすると図３に示すようにアーム部５１が操作杆当接部４０ａを押し下げてラッチ４０を解錠位置とする。
前記操作杆５０をラッチ施錠方向に揺動すると、そのアーム部５１がケース３０（アウトケース３１の開口部３５）に接して第３の位置となる（図４参照）。
また、この状態において、ラッチ４０が施錠位置の時に、ラッチ本体４１の空洞部４０ｂの上面、スライダー４２の開口窓４４の上内面（つまり、ラッチ４０のラッチ部４０ａの下面４０ｆ）とアーム部５１との間の間隔は、ラッチ４０の施錠位置から解錠位置までの移動距離よりも広い。 Thus, when the latch 40 is in the locked position, the arm portion 51 is in contact with the operating rod contact portion 40c of the latch 40 and is held at the first position. When the operating rod 50 is swung in the unlocking direction to the second position, as shown in FIG. 3, the arm portion 51 pushes down the operating rod contact portion 40a to set the latch 40 to the unlocking position.
When the operating rod 50 is swung in the latch locking direction, the arm portion 51 comes into contact with the case 30 (the opening 35 of the outcase 31) to be in the third position (see FIG. 4).
In this state, when the latch 40 is in the locked position, the upper surface of the cavity portion 40b of the latch body 41, the upper inner surface of the opening window 44 of the slider 42 (that is, the lower surface 40f of the latch portion 40a of the latch 40), and the arm portion 51. Is wider than the moving distance from the locking position of the latch 40 to the unlocking position.

前記ラッチ４０の操作杆当接部４０ｃは円弧形状で、操作杆５０が図２に示す第１の位置の時にはアーム部５１の第１点５１ａが操作杆当接部４０ｃに接している。
この状態から操作杆５０を第２の位置に揺動すると図３に示すようにアーム部５１の第２点５１ｂが操作杆当接部４０ｃにおける前記第１点５１ａが接している位置と異なる位置に接する。
要するに、操作杆５０を第１の位置から第２の位置に揺動する際に、その操作杆５０のアーム部５１と操作杆当接部４０ｃとの接する位置は、アーム部５１の長手方向に順次移動する。 The operating rod contact portion 40c of the latch 40 has an arc shape. When the operating rod 50 is in the first position shown in FIG. 2, the first point 51a of the arm portion 51 is in contact with the operating rod contact portion 40c.
When the operating rod 50 is swung to the second position from this state, as shown in FIG. 3, the second point 51b of the arm 51 is different from the position where the first point 51a is in contact with the operating rod contact portion 40c. To touch.
In short, when the operating rod 50 is swung from the first position to the second position, the position where the arm 51 of the operating rod 50 and the operating rod contact portion 40c are in contact with each other is in the longitudinal direction of the arm 51. Move sequentially.

したがって、操作杆５０でラッチ４０を施錠位置から解錠位置に移動する時に、アーム部５１と操作杆当接部４０ｃの１点に集中して負荷が作用しないので、そのアーム部５１と操作杆当接部４０ｃの接する部分が異常摩耗等することがない。   Therefore, when the latch 40 is moved from the locked position to the unlocked position by the operating rod 50, the load is not concentrated on one point of the arm portion 51 and the operating rod contact portion 40c. The contact portion of the contact portion 40c will not be abnormally worn.

また、操作杆５０が第１の位置の時に、そのアーム部５１の揺動中心（ピン５４）とアーム部５１における操作杆当接部４０ｃと接した第１点５１ａがほぼ同一高さで、かつ第１点５１ａは操作杆当接部４０ｃの頂部（最も高い部分）に接しているので、この状態から操作杆５０を第２の位置に向けて揺動した時にアーム部５１の長手方向に順次ずれた位置が操作杆当接部４０ｃの円弧状面に順次接し、スムーズにラッチ４０を解錠位置に移動できる。   Further, when the operating rod 50 is in the first position, the swing point (pin 54) of the arm portion 51 and the first point 51a in contact with the operating rod contact portion 40c in the arm portion 51 are substantially the same height. The first point 51a is in contact with the top (highest portion) of the operating rod contact portion 40c, so that when the operating rod 50 is swung toward the second position from this state, the first portion 51a extends in the longitudinal direction of the arm portion 51. The sequentially shifted positions sequentially contact the arcuate surface of the operating rod contact portion 40c, and the latch 40 can be smoothly moved to the unlocked position.

前記弾性部材６０はコイルスプリングで、インナーケース３２の支持片３２ｃとラッチ４０のラッチ部４０ａの下面４０ｆとの間に設けてある。
前記ラッチ４０には、その自重と前記操作杆５０の自重による下向揺動力とで解錠位置に向かう力が作用する。
前記力よりも弾性部材６０の弾性が大きく、操作杆５０をケース３０に押しつけてラッチ４０を施錠位置に保持している。例えば、アーム部５１をアウトケース３１の開口部３５の上端面に当接してラッチ４０を施錠位置に保持している。この場合には、操作杆５０の第１の位置と第３の位置が同一である。
なお、前記の力と前記弾性部材６０の弾性をバランスしてラッチ４０を施錠位置に保持するようにしても良い。この場合には操作杆５０の第１の位置と第３の位置が異なり、操作杆５０をラッチ移動方向に移動してケース３０に接して第３の位置とする。 The elastic member 60 is a coil spring and is provided between the support piece 32c of the inner case 32 and the lower surface 40f of the latch portion 40a of the latch 40.
A force toward the unlocking position acts on the latch 40 by its own weight and a downward swinging force due to the weight of the operating rod 50.
The elasticity of the elastic member 60 is greater than the force, and the operating rod 50 is pressed against the case 30 to hold the latch 40 in the locked position. For example, the arm 51 is brought into contact with the upper end surface of the opening 35 of the outcase 31 to hold the latch 40 in the locked position. In this case, the first position and the third position of the operating rod 50 are the same.
The latch 40 may be held in the locked position by balancing the force and the elasticity of the elastic member 60. In this case, the first position and the third position of the operating rod 50 are different from each other, and the operating rod 50 is moved in the latch moving direction to come into contact with the case 30 to be the third position.
