本考案は腕時計ケースとバンドの接合部の構造に関する
ものである。[Detailed Description of the Invention] The present invention relates to the structure of the joint between the wristwatch case and the band.
最近、腕時計のケース及びバンドは装飾性を重要視され
る為、薄型化、異形化する傾向になっている。Lately, watch cases and bands have become more important in terms of decorativeness, so they tend to be thinner and more irregularly shaped.
その為ケースとバンドを一体化したものが強く要望され
てきているが、ケースとバンドを同一部材で製造するに
は技術的にも非常に難く、製造工程も複雑となる為、お
のずから制限があり困難である。For this reason, there is a strong demand for a case and band that are integrated, but manufacturing the case and band from the same material is technically extremely difficult and the manufacturing process is complicated, so there are natural limitations. Have difficulty.
したがってケースとバンドとの別部材を接合し一体化す
る方法が研究開発されてきた。Therefore, research and development has been conducted on methods of joining and integrating the separate members of the case and the band.
すなわち円弧状の側面を持つケースと金属バンドの接合
において、各々の接合面を所要の形状に加工した後両方
を突き合せ、スポット溶接で仮止め固定し、接合部装置
ロウして炉中加熱等でロス接を行い、一体感のある時計
外装部品としていた。In other words, when joining a case with an arc-shaped side surface and a metal band, each joining surface is processed into the desired shape, then both are butted together, temporarily fixed by spot welding, the joined part is brazed, heated in a furnace, etc. loss welding was performed to create a watch exterior part with a sense of unity.
しかし従来は、ケースとバンドの接合面の円弧寸法を同
寸法で加工した為、各々の加工法により加工公差が異な
り接合部のスキマが不均一となり、ロウ接時にロウ材が
接合部全面に浸透せず、外観不良となることが多かった
。However, in the past, the arc dimensions of the joint surfaces of the case and band were processed to the same dimensions, so the processing tolerances differed depending on the processing method, resulting in uneven gaps at the joint, and the brazing metal permeated the entire surface of the joint during soldering. This often resulted in poor appearance.
また接合部の寸法が、たとえ人−でも、スポット溶接に
おいては面接触でなく、点接触の集合となり、抵抗が場
所により不均一となる為、通電々流が分流し、電気的入
力が同じでも、チリ、燈火、ブローホール等の外観不良
、及び溶接強度不足からなる仮止め力不足となって現わ
れ、均一な溶接結果が得られないという欠点があった。In addition, even if the dimensions of the joint are made manually, spot welding results in a collection of point contacts rather than surface contact, and the resistance is uneven depending on the location, so the current flow is divided, even if the electrical input is the same. This has the disadvantage that uniform welding results cannot be obtained due to appearance defects such as dust, lights, and blowholes, and insufficient temporary fixing force due to insufficient welding strength.
本考案はこれらの欠点を除去する為、ケースの円弧寸法
に対してバンドの円弧寸法を小さく形成して、バンドの
両端で接合させた接合部の構造に関するもので以下本考
案を図面に基づき実施例により説明する。In order to eliminate these drawbacks, the present invention relates to a joint structure in which the arc dimension of the band is formed smaller than the arc dimension of the case, and the bands are joined at both ends.The present invention is implemented based on the drawings below. Let's explain by example.
図面は本考案の一実施例を示すもので第１図は時計ケー
スとバンドの接合状態を示した平面図である。The drawings show an embodiment of the present invention, and FIG. 1 is a plan view showing a state in which a watch case and a band are joined.
ステンレス鋼ケース１は大円弧２の寸法が５２．５ｍｍ
及び小円弧３の寸法が５ｍｍの半径の組合せからなる外
形形状のもので、切削及び機械研摩加工により成形を行
ったものである。The dimension of the large arc 2 of the stainless steel case 1 is 52.5 mm.
The outer shape is formed by a combination of a radius of 5 mm and a small arc 3 of 5 mm, and is formed by cutting and mechanical polishing.
ステンレス鋼メツシュバンド４は接合部の円弧寸法を半
径５０ ｍｍで切削若しくは研削加工により成形加工を
行ったものである。The stainless steel mesh band 4 is formed by cutting or grinding the arc size of the joint part to a radius of 50 mm.
尚仮止めスポット溶接は、コンデンサータイプの溶接機
によりエネルギー容量１００ ｗｓで行った。The temporary spot welding was performed using a condenser type welding machine with an energy capacity of 100 ws.
これによると、ケース及びバンドの加工公差に多少のバ
ラツキがあろうとも、完全にバンドの両端５，５′がケ
ースに接触する。According to this, even if there are some variations in the processing tolerances of the case and the band, both ends 5 and 5' of the band completely contact the case.
したがって、電流の通路を制限するため、電流密度が高
くなり、従来の接合法に比べ電気的人力が同じでも溶接
強度が増加する。Therefore, since the current path is restricted, the current density is increased, and the welding strength is increased with the same electrical power compared to the conventional joining method.
又接触面が小さく限定される為に抵抗のバラツキが少な
くなり、チリ、燈火、ブローホール等の溶接不良が少な
くなり側面及び平面の外観品質が非常に向上した。In addition, since the contact surface is small and limited, variations in resistance are reduced, welding defects such as dust, lights, and blowholes are reduced, and the appearance quality of the side and plane surfaces is greatly improved.
尚仮止めスポット溶接後の炉中ロウ接において、ケース
とバンドの完全な接合を行うが実施例では接合部の中央

細管現象により充分接合部のスキマへ浸透する為に、外
観的にも同一部材で製造したものとまったくかわらない
一体感のある時計外装部品の製造が可能となった。In addition, the case and band are completely joined during furnace brazing after temporary spot welding, but in the example, the gap 6 at the center of the joint is at most about 0.065 mm, and the brazing metal is sufficiently joined by capillary action. Because it penetrates into the gaps between parts, it has become possible to manufacture watch exterior parts that have a sense of unity and look exactly the same as those made from the same material.
第２図は本考案の他の実施例を示す平面図で、ケースの

明白である。FIG. 2 is a plan view showing another embodiment of the present invention, in which the arc size of the case and the arc size of the contact portions of both ends 7, 7' of the band are made the same, and a clearance groove 6' is provided in the center of the band. It is clear that the same effect can be obtained by temporary spot welding at both ends 7, 7' of the band and brazing at the gap groove 6'.
又ケースの円弧寸法の変化に対しては、接合部のスキマ
量をある程度一定にする必要があるが、スキマ量に対し
て炉中ロウ接時のロス材の量を調整しても良好な外観品
質が保持できる。In addition, it is necessary to keep the gap amount at the joint part constant to some extent in response to changes in the arc dimensions of the case, but even if the amount of loss material during furnace brazing is adjusted to the gap amount, a good appearance can be achieved. Quality can be maintained.
