従来、腕時計のバンドやブレスレットなどに用いられる装飾品用駒には、デザインに合わせて様々な構造が提案されている。特に、バンドの駒にセラミックスを用いた装飾品用駒は、セラミックスが傷つきにくく耐磨耗性に優れることから高級な装飾品に用いられるようになってきている。この様なセラミックスを用いる例として、特許文献1には、時計の装備方向に通ずるストレート形状の貫通穴を駒本体の厚み内に設けた略方形のバンド駒と、バンド駒の貫通穴と連通する開口を棒状本体の軸線内に設け、棒状本体の側端面から軸線内の開口と連通する軸受け孔を軸両側に設け、時計の装備側に向けて棒状本体の軸両端寄りから突起を設けたスペーサと、板状本体の前後辺を軸継ぎ手として形成した連鎖片と、連結ピンとを所定数複数個組み合わせてなり、各突起を貫通穴の穴両端内に嵌め合わせてスペーサを時計の装備側前側に位置するバンド駒と一体に組み立てると共に、相前後するバンド駒の間にスペーサで隙間を保ってバンド駒とスペーサとを交互に組み合わせ、連鎖片を相前後する軸継ぎ手で互いに組み合わせて軸継ぎ手をスペーサの開口内に位置し、板状本体をバンド駒の貫通穴内に位置させて連鎖片とバンド駒並びにスペーサとを組み合わせると共に、連結ピンを各スペーサの軸受け孔と当該スペーサの開口内に位置する連鎖片の軸継ぎ手とに挿置し、これら組み合わされた各部からバンド本体を鎖状に組み立てた腕時計用バンドが開示されている。 Conventionally, various structures have been proposed for decorative pieces used for wristbands, bracelets and the like according to the design. In particular, a decorative piece using ceramics for the band piece has come to be used for high-grade decorative items because ceramics are hard to be damaged and have excellent wear resistance. As an example of using such ceramics, Patent Document 1 discloses a substantially rectangular band piece provided with a straight through hole in the thickness of the piece main body in the watch body direction, and an opening communicating with the through hole of the band piece. Is provided in the axis of the rod-shaped main body, bearing holes communicating with the opening in the axis from the side end surface of the rod-shaped main body are provided on both sides of the shaft, and a spacer provided with protrusions from both ends of the rod-shaped main body toward the equipment side of the watch A combination of a predetermined number of chain pieces formed with the front and rear sides of the plate-like body as shaft joints and a plurality of connecting pins, and each protrusion is fitted into both ends of the through hole so that the spacer is positioned on the front side of the equipment side of the watch Assemble the band piece together, and keep the gap between the adjacent band pieces with spacers, and combine the band pieces and spacers alternately. The grip is positioned in the opening of the spacer, the plate-shaped main body is positioned in the through hole of the band piece, the chain piece, the band piece and the spacer are combined, and the connecting pin is placed in the bearing hole of each spacer and the opening of the spacer.

In a band using ceramic pieces, further ingenuity was required to solve these problems appropriately.
例えば、特許文献1の腕時計用バンドは、スペーサを駒本体の間に配置することで、バンドを側面から見るとスペーサの側面に連結ピンの端部が見えることから、連結用の部品の一部が露出して装飾性が損なわれるという問題があった。 For example, the wristwatch band of Patent Document 1 is a part of the connecting parts because the end of the connecting pin can be seen on the side of the spacer when the band is viewed from the side by disposing the spacer between the pieces. There is a problem that the decorativeness is impaired due to exposure.

このように、本実施形態の例では、装飾品用駒は、第2駒2の間隔が第2駒2と連結具3とピン4とにより拘束されるため、第1駒1のくぼみ部16に収容された第2駒2と第1駒1のくぼみ部16とのクリアランスを装飾品用駒の全体で均等に保つことが可能となる。これにより、第1駒1と第2駒2をセラミックス製としても、装飾品用駒の特定の部分に繰り返し大きな摩擦が生じて第1駒1と第2駒2とが傷ついたり磨耗したりして、装飾品用駒の寿命が低下したり外観を損ねることを抑制できる。 As described above, in the example of the present embodiment, the decorative piece has a recess 16 of the first piece 1 because the interval between the second pieces 2 is constrained by the second piece 2, the connector 3, and the pin 4. It is possible to keep the clearance between the second piece 2 accommodated in the first piece 1 and the indented portion 16 of the first piece 1 uniform throughout the ornamental piece. As a result, even if the first piece 1 and the second piece 2 are made of ceramics, the first piece 1 and the second piece 2 may be damaged or worn due to repeated large friction in specific parts of the decorative piece. It is possible to suppress the life of the decorative piece from being deteriorated and the appearance from being deteriorated.
図7は、本実施形態である装飾品用駒の組み付け図の一例を示す、(a)は平面図であり、(b)は正面図であり、(c)は装飾品用駒を曲げた状態を示す断面図である。 FIG. 7 shows an example of an assembly drawing of the ornamental piece according to this embodiment, (a) is a plan view, (b) is a front view, and (c) is a state where the ornamental piece is bent. FIG.
図7(a)〜(c)に示す例では、連結具3やピン4は、第1駒1と第2駒2との内部に収容されている。そのため装飾品用駒70を手首に巻き付けたとき、上面側から見ると、第1駒1の隙間Aからは第2駒2が見えるだけで連結具3が露出することはない。さらに、第2駒2の端面22側から見ると、ピン4は第1駒1のくぼみ部16の内側にあるためピン4の端部が露出することもなく、美しい外観を有する装飾品用駒70を得ることができる。 In the example shown in FIGS. 7A to 7C, the connector 3 and the pin 4 are accommodated inside the first piece 1 and the second piece 2. Therefore, when the ornamental piece 70 is wound around the wrist, when viewed from the upper surface side, only the second piece 2 can be seen from the gap A of the first piece 1 and the connector 3 is not exposed. Further, when viewed from the end face 22 side of the second piece 2, the pin 4 is inside the recessed portion 16 of the first piece 1, so that the end of the pin 4 is not exposed and has a beautiful appearance. You can get 70.
