【発明の属する技術分野】
本発明は、コンパクト、とくにコンパクトの蓋係止機構に関する。
【０００２】
【従来の技術】
コンパクトの蓋係止機構として、図１３に示すような廻動式操作部材は従来より知られている。
図において、Ａｄはケース本体、Ｂｄは蓋体、Ｃｄは蓋係止機構の操作部材である。
操作部材Ｃｄは、ケース本体Ａｄに設けられた軸ピン５０に枢着部５１を介して廻動自在に取着されており、押え板５２を押圧したときに、作動板５３が蓋体Ｂｄのフック５４に衝接し、フック５４をケース本体Ａｄの係止壁面に設けたフック５５から外して蓋体Ｂｄを開くようにしている。
【０００３】
【発明が解決しようとする課題】
しかしながら、操作部材Ｃｄの枢着部５１と軸ピン５０との間ではわずかであるが遊びを設け、また、軸ピン５０に対して枢着部５１が摺動できるようになっている。
【０００４】
そのため、廻動操作時に、操作部材Ｃｄの底板５６とケース本体Ａｄとの間にきしみが生じるという問題があった。
また、底板５６の端部５６ａがケース本体Ａｄの係止壁面に喰い込み、操作部材Ｃｄが動かなくなるという問題があった。
さらには、操作部材Ｃｄが喰い込み部を軸として廻動し、枢着部５１が軸ピン５０から離れ、操作部材Ｃｄの作動板５３がフック５４を押し上げることができないで、蓋体Ｂｄが開かなかったり、操作部材Ｃｄ自体が取り外れたりする危険性もあった。
【０００５】
本発明は、上記の問題を解決することを課題とし、きしみ、フックのケース本体への喰い込みをなくした廻動式の操作部材を具えたコンパクトの蓋係止機構を提供することを目的とする。
【０００６】

The cover body Bb can be opened by engaging with the engagement portion 46 on the back surface and releasing the engagement between the hook 9b of the case main body Ab and the hook 18b of the cover body Bb.
Then, the locking surface 24Ab on the upper surface of the end edge of the bottom plate 24b is engaged with the stopper 45 to maintain a predetermined rotational position.
[0030]
Next, a modified example of the third embodiment will be described.
In the present embodiment, in the third embodiment, the engaging wall surface 6b is changed to the stopper 45, and an engagement recess 41 having the upper surface of the second embodiment as the stopper surface 40 is formed, and the bottom plate 24b of the operation member 20b is formed. Further, the central portion is protruded, and the locking piece 42 is protruded.
[0031]
When the lid is opened, as in the third embodiment, when the presser portion 25b is pushed down, the operation member 20b rotates and the edge of the upper plate 23b is engaged with the engaging portion 46 on the back surface of the lid Bb at both ends of the hook 18b. The cover Bb can be opened by releasing the engagement between the hook 9b of the case main body Ab and the hook 18b of the cover Bb.
Then, the locking piece 42 of the bottom plate 24b of the operation member 20b is inserted into the engaging recess 41, and the locking piece 42 engages with the stopper surface 40 to maintain a predetermined rotational position.
[0032]
In the third embodiment, the engaging portion 46 on the back surface of the lid Bb is provided on both sides of the locking piece 16b. However, it may be provided over the entire length of the edge 47, and the entire circumference of the edge of the lid Bb is wide. It is good also considering the both sides of the locking piece 16b as an engaging part.
[0033]
In each of the embodiments described above, the operation member includes a presser plate and a side plate, and an upper plate and a bottom plate having a center portion as a notch. In the third embodiment, the side plate is provided on the engaging portion 46 on the back surface of the lid Bb. The upper end of 22b may be engaged, and the upper plate may not be provided.
[0034]
【The invention's effect】
Since this invention is comprised as mentioned above, there exists the following effect.
Since the stopper protruding from the wall surface on the locking wall surface of the case body or the engaging recess with the upper surface as the stopper surface is provided to lock the bottom plate of the operation member, the case body and the operation member are It was possible to eliminate the creaking between the two and the biting of the operation member into the case body.
