止できるようにせんとするにある。[Detailed description of the invention] This invention relates to a watch clasp device, and its purpose is to use an appropriate force to hold the snap pieces of the front cover into the shaft pins without deforming and correcting the snap pieces of the front cover after assembly. It is located so that it can be locked in place.

なけれは゛ならないという欠点があった。Conventional wristwatch clasp devices have a hook that locks on the rear shaft pin of the frame of the stopper fixed to the band, and a snap piece of the front cover that locks on the front shaft pin. Since neither the piece nor the shaft pin has any elasticity, the snap piece cannot be properly locked to the shaft pin due to a dimensional error in the amount after assembly, and therefore the snap piece must be deformed and corrected one by one.
本考案はフックと軸ピン間に弾性をもたせるようにして
従来の欠点を除くようにしたものである。The present invention provides elasticity between the hook and the shaft pin to eliminate the drawbacks of the prior art.
次に添附図面に示した本考案の一実施例について詳細に
説明する。Next, an embodiment of the present invention shown in the accompanying drawings will be described in detail.
１は一方のバンド、２はバンド１の所定位置に固定した
止め具でバンド１両側より上方に突出したフレーム２ａ
の前・後部に夫々軸ピン３，４が固定しである。1 is one of the bands, 2 is a frame 2a that is a stopper fixed at a predetermined position of the band 1 and protrudes upward from both sides of the band 1.
Axial pins 3 and 4 are fixed to the front and rear of the shaft, respectively.
５はバンド押え板、６は表カバー、６ａはそのスナップ
片、７はフックで、表カバー６とフック７は他方のバン
ド８端部に固定した軸ピン９に枢着しである。5 is a band holding plate, 6 is a front cover, 6a is a snap piece thereof, and 7 is a hook. The front cover 6 and the hook 7 are pivotally connected to a shaft pin 9 fixed to the end of the other band 8.
このような構造は従来周知であるが、本考案はこのフッ
ク７の軸ピン４と当接する内面７ａに板は゛ね１０の中
間部を固定しである。Although such a structure is conventionally known, the present invention fixes the intermediate portion of the plate spring 10 to the inner surface 7a of the hook 7 that comes into contact with the shaft pin 4.
次に作用について説明する。Next, the effect will be explained.
フック７を軸ピン４に係止し、次いで表カバー６のスナ
ップ片６ａを軸ピン３に係止する。The hook 7 is locked to the shaft pin 4, and then the snap piece 6a of the front cover 6 is locked to the shaft pin 3.
この時各部品の寸法誤差によりスナップ片６ａが軸ピン
３に対して係止がきつくても、フック７の内面７ａの板
ばね１０が弾性を有しているのでフック７と軸ピン４間
で前記スナップ部の誤差を吸収し、スナップ片６ａを適
切な力で軸ピン３に係止することができる。At this time, even if the snap piece 6a is tightly locked against the shaft pin 3 due to dimensional errors of each component, the leaf spring 10 on the inner surface 7a of the hook 7 has elasticity, so that the snap piece 6a is not tightly locked between the hook 7 and the shaft pin 4. It is possible to absorb the error of the snap portion and lock the snap piece 6a to the shaft pin 3 with an appropriate force.
本考案によればフックと軸ピン間に弾性をもたせている
ので、組立後表カバーのスナップ片をいちいち変形修正
しなくても適切な力でスナップ片を軸ピンに係止できる
。According to the present invention, elasticity is provided between the hook and the shaft pin, so that the snap piece of the front cover can be locked to the shaft pin with an appropriate force without having to deform and correct the snap piece of the front cover every time after assembly.
