Description

本発明は、中留及び腕時計に関するものである。   The present invention relates to a middle ring and a wristwatch.

従来、腕時計等の機器ケースの一端側に取り付けられた第１のバンドと他端側に取り付けられた第２のバンドとを連結させる中留として、三つ折れ方式の中留が知られている。
三つ折れ方式の中留は、一端側が第１のバンドの自由端側に取り付けられた下板と、一端側が第２のバンドの自由端側に取り付けられるとともに、折り畳み時において下板の外側面に重なり合うように配置されるカバー部材と、一端側が下板の他端側に回動自在に連結されるとともに、他端側がカバー部材の他端側に回動自在に連結される中板とを備えている。 2. Description of the Related Art Conventionally, a three-fold type intermediate retainer is known as a intermediate retainer that connects a first band attached to one end of a device case such as a wristwatch and a second band attached to the other end. .
The three-fold type middle end has a lower plate whose one end is attached to the free end of the first band, and one end is attached to the free end of the second band, and the outer surface of the lower plate when folded. A cover member disposed so as to overlap with the other end, and an intermediate plate having one end side rotatably connected to the other end side of the lower plate and the other end side rotatably connected to the other end side of the cover member. I have.

このような三つ折れ方式の中留のカバー部材は、バンドを装着した際、バンドの駒とともにバンドの外装を構成するため、このカバー部材に装飾を施すことでバンドのデザイン性を向上させることができる。
例えば特許文献１には、カバー部材を表板とこの表板の表面を覆うように取付固定されたゴム製のカバーとで構成した中留構造が記載されている。
このような構成によれば、ゴム製のカバーの形状や色を変えたり、カバーの一部にロゴ等の形状に切り欠いた窓を設ける等により、単なる板状のカバー部材を設ける場合よりもバリエーション豊かなデザインを楽しむことができる。
また、カバー部材に直接装飾部材を嵌装する等によりデザイン性を向上させることも考えられる。 Since the cover member of such a three-fold type dome is configured to form the exterior of the band together with the band piece when the band is mounted, the design of the band can be improved by decorating the cover member. Can do.
For example, Patent Document 1 describes a middle structure in which a cover member is constituted by a front plate and a rubber cover attached and fixed so as to cover the surface of the front plate.
According to such a configuration, by changing the shape and color of the rubber cover, or by providing a window cut out in the shape of a logo or the like in a part of the cover, etc., than when providing a simple plate-like cover member. You can enjoy a variety of designs.
It is also conceivable to improve the design by directly attaching a decorative member to the cover member.

特開２００２−１９１４１５号公報JP 2002-191415 A

しかしながら、特許文献１に記載されているようにカバー部材を表板とこれに被覆されるゴム製のカバーとで構成した場合には、カバー部材の厚みが厚くなり、中留部分が不自然に大きくなってバンド全体との調和を欠いてしまう。   However, when the cover member is composed of a front plate and a rubber cover coated thereon as described in Patent Document 1, the thickness of the cover member is increased and the middle portion is unnatural. It grows up and lacks harmony with the whole band.

この点、カバー部材に直接装飾部材を嵌装する手法によれば、中留部分の大きさを変えずにデザイン性を向上させることができる。
しかし、カバー部材の表面に開口部を設けて、これに装飾部材を嵌め込むだけでは装飾部材が外れやすい。 In this regard, according to the technique in which the decorative member is directly fitted to the cover member, the design can be improved without changing the size of the middle portion.
However, the decorative member can be easily detached simply by providing an opening on the surface of the cover member and fitting the decorative member into the opening.

そこで、装飾部材を変形可能な柔らかい材料（例えばウレタン等）で形成し、この装飾部材に、カバー部材の開口部よりも大きな脚部を設けて、脚部を押し縮めて変形させながら開口部に押し込むと、開口部を通過後に脚部が元の大きさ・形状に復元し、カバー部材の裏面側に係止され抜けなくなる構成が考えられる。
しかし、このような手法では装飾部材を変形可能な材料で形成する必要があり、自由に材料を選択することができないため、デザインのバリエーション等が制限されてしまうとの問題がある。 Therefore, the decorative member is made of a deformable soft material (for example, urethane), and a leg larger than the opening of the cover member is provided on the decorative member. When pushed in, a configuration is conceivable in which the leg portion is restored to its original size and shape after passing through the opening, and is locked to the back side of the cover member and cannot be removed.
However, in such a method, it is necessary to form the decorative member with a deformable material, and the material cannot be freely selected. Therefore, there is a problem that design variations and the like are limited.

本発明は以上のような事情に鑑みてなされたものであり、各種の材料を用いてバリエーション豊富な装飾をカバー部材に施すことができ、デザイン性に優れた中留及び腕時計を提供することを目的とするものである。   The present invention has been made in view of the circumstances as described above, and is capable of applying a variety of decorations to the cover member using various materials, and to provide a stud and a wristwatch excellent in design.
