31aは、一段低くなっていることを特徴とするものであ
る。The present invention is a three-fold clasp that is released by the operation plate of the lock mechanism attached to the front cover.
The lock mechanism is composed of a hollow frame member, an operation plate therein and an elastic member for pressing the operation plate outward, and the operation plate is attachable to and detachable from the locking claw of the lower plate of the three-fold clasp. In the clasp structure in which the portion of the operating plate that faces the locking surface pushes down the head of the locking pawl when releasing, locking of the operating plate 31 that is attached to and detached from the locking pawl 30 surface
31a is characterized by being lowered one step.
以下、図面に基づいて本考案の詳細を説明する。 Hereinafter, details of the present invention will be described with reference to the drawings.
第１図は本考案の一実施例であるロック（係止）状態の
中留構造を示す一部切欠平面図であり、第２図は断面図
である。FIG. 1 is a partially cutaway plan view showing a clasp structure in a locked state according to an embodiment of the present invention, and FIG. 2 is a sectional view.
三つ折の表カバーに相当する部分は上枠21と下枠22の固
着により構成されている。下枠22の一端には一半バンド
23がバネ棒24により軸着している。下枠22の他端は巾方
向の突起25、25′により中板26に軸着している。中板26
と下板27は左端で軸着していて、下板27の他端には他半
バンド28がバネ棒29により軸着している。The portion corresponding to the three-fold front cover is formed by fixing the upper frame 21 and the lower frame 22. One half band at one end of the lower frame 22
23 is attached by a spring rod 24. The other end of the lower frame 22 is axially attached to the middle plate 26 by projections 25 and 25 'in the width direction. Middle plate 26
The lower plate 27 is pivotally attached at the left end, and the other half band 28 is pivotally attached to the other end of the lower plate 27 by a spring rod 29.
第６図に示すように下板27には係止爪30が折立て形成さ
れている。係止爪30は中板26の逃げ穴26a及び下枠22の
逃げ穴22aを貫通している。係止爪30には係止のための
ガイド斜面30aと係止面30b及び反対側には跳ね上げのた
めのガイド斜面30cが形成されている。As shown in FIG. 6, locking claws 30 are formed on the lower plate 27 so as to be upright. The locking claw 30 penetrates the clearance hole 26a of the middle plate 26 and the clearance hole 22a of the lower frame 22. The locking claw 30 is formed with a guide slope 30a and a locking surface 30b for locking, and a guide slope 30c for flipping up on the opposite side.
中板26と下板27で形成される中空部22a、26aには操作板
31が一部を外に突出させるように配置されている。ま
た、操作板31を外に押しつけるようにバネ32が配置され
ている。操作板31は板材の抜き曲げ加工でできていて、
係止爪30と着脱する係止面31aは一段低くなっている。An operation plate is provided in the hollow portions 22a, 26a formed by the middle plate 26 and the lower plate 27.
31 is arranged so that a part thereof is projected outward. Further, a spring 32 is arranged so as to press the operation plate 31 to the outside. The operation plate 31 is made by punching and bending the plate material,
The engaging surface 31a that is attached to and detached from the engaging claw 30 is one step lower.
第７図（Ａ）、（Ｂ）に係止爪30と操作板31の着脱の状
態を示してある。7 (A) and 7 (B) show a state in which the locking claw 30 and the operation plate 31 are attached and detached.
第７図（Ａ）はロック（係着）状態を示していて、操作
板31の係止面31aは係止爪30の係止面30bに接している
が、相対する斜面部31bは係止爪30のガイド斜面30cとの
間に十分隙間を取った状態に設定されている。FIG. 7 (A) shows a locked (engaged) state, in which the locking surface 31a of the operation plate 31 is in contact with the locking surface 30b of the locking claw 30, but the opposite slope portion 31b is locked. The claw 30 and the guide slope 30c are set to have a sufficient gap.
第７図（Ｂ）はロック解除（係脱）の状態を示すもの
で、丁度操作板31を押した時である。操作板31の係止面
31aと係止爪30の係止面30bとは離れ、操作板31の斜面部
31bが係止爪のガイド斜面30cを上方に滑動して行って、
操作板31を含めて中留の上枠21と下枠22の全体が上方に
自動的に跳ね上がることになる。FIG. 7B shows a state of unlocking (engagement / disengagement), which is when the operation plate 31 is just pushed. Locking surface of operation plate 31
31a and the locking surface 30b of the locking claw 30 are separated from each other, and the slope portion of the operation plate 31 is separated.
31b slides on the guide slope 30c of the locking claw upwards,
The entire upper frame 21 and lower frame 22 of Nakadome including the operation plate 31 will automatically jump up.
また、操作板31の斜面部31bは絶対に必要でなく、単な
る抜きの断面でも良い。Further, the inclined surface portion 31b of the operation plate 31 is not absolutely necessary, and may have a simple cross section.
以上説明したように、本考案の構造によれば、三つ折中
留を解除する際にワンプッシュで操作板の斜面部が係止
爪の頭部を押し下げるようにしたことから、解除作業が
非常に容易となった。As described above, according to the structure of the present invention, when the three-fold clasp is released, the beveled surface of the operation plate pushes down the head of the locking claw with one push. Became easier.
すなわち、ロック機構を解除するときに、操作板を押す
だけで、ロック状態を解除し、更に中留部分を持ち上げ
ることができる。That is, when the lock mechanism is released, the lock state can be released and the clasp part can be further lifted by simply pushing the operation plate.
また、係止爪に着脱する、操作板の係止面が抜き曲げ加
工により、一段低く形成されているため、部品が集中し
てあつまり、厚くなりがちな係止爪の部分を、薄い構造
にすることができるようになった。Also, since the locking surface of the operation plate that is attached to and detached from the locking claws is formed one step lower by punching and bending, parts are concentrated and the locking claws that tend to be thicker have a thinner structure. I was able to do it.
