As a result, the wristwatch is assembled.

このような腕時計ケース1は、外装部材6がサファイア、ガラス、セラミックなどの材料で形成されてことにより、カラー化が可能になるため、装飾性および色彩性が高く、かつ保護部材7を除く箇所の外装部材6が露出していることにより、デザイン性に優れ、商品価値の高いものが得られる。また、この腕時計では、腕時計ケース1が外部から衝撃を受けても、その衝撃を保護部材7で受け止めて、サファイア、ガラス、セラミックなどの硬い脆性材料の外装部材6が破損しないようにすることができる。 In such a wristwatch case 1, since the exterior member 6 is made of a material such as sapphire, glass, or ceramic, it can be colored, so that it is highly decorative and colorful, and the protective member 7 is excluded. Since the exterior member 6 of the above is exposed, a product having excellent design and high commercial value can be obtained. Further, in this wristwatch, even if the wristwatch case 1 receives an impact from the outside, the impact is received by the protective member 7 so that the exterior member 6 of a hard brittle material such as sapphire, glass, or ceramic is not damaged. can.

例えば、腕時計ケース1が側方から衝撃を受けた際には、その衝撃を保護部材7の第1保護部16で受け止めることができる。このときには、第1保護部16と外装部材6の第1外装部12との間に部分的に配置された緩衝部材14の第1緩衝部18によって衝撃が緩衝される。 For example, when the wristwatch case 1 receives an impact from the side, the impact can be received by the first protective portion 16 of the protective member 7. At this time, the impact is buffered by the first cushioning portion 18 of the cushioning member 14 partially arranged between the first protective portion 16 and the first exterior portion 12 of the exterior member 6.

すなわち、第1緩衝部18は、硬度の異なる2種類の第1、第2緩衝層14a、14bを積層した構造で、第1緩衝層14aは硬度が30°〜50°程度の低硬度のシリコーンゴムであることにより、衝撃に応じて弾力的に変形して衝撃を吸収し、第2緩衝層14bは硬度が60°程度の高硬度で減衰率の防振用のシリコーンゴムであることにより、衝撃力を分散させて一点に集中させないようにすることができる。 That is, the first buffer layer 18 has a structure in which two types of first and second buffer layers 14a and 14b having different hardness are laminated, and the first buffer layer 14a is a low-hardness silicone having a hardness of about 30 ° to 50 °. Since it is a rubber, it elastically deforms in response to an impact to absorb the impact, and the second buffer layer 14b is a silicone rubber having a high hardness of about 60 ° and a damping rate for vibration isolation. The impact force can be dispersed so that it is not concentrated on one point.

この場合、第1保護部16と第1外装部12との間には、第1緩衝部18によって隙間S1が設けられているので、第1緩衝部18の第1緩衝層14aがその厚み方向に弾性変形しても、第1保護部16が第1外装部12に接触することがない。このため、第1外装部12がサファイア、ガラス、セラミックなどの硬い脆性材料で形成されていても破損することがない。 In this case, since the gap S1 is provided between the first protective portion 16 and the first exterior portion 12 by the first cushioning portion 18, the first cushioning layer 14a of the first cushioning portion 18 is in the thickness direction thereof. Even if it is elastically deformed, the first protective portion 16 does not come into contact with the first exterior portion 12. Therefore, even if the first exterior portion 12 is made of a hard brittle material such as sapphire, glass, or ceramic, it will not be damaged.

また、このときには、第1保護部16と第1外装部12との間に第2保護部17の側面部17bが配置されているが、この第2保護部17の側面部17bと第1外装部12との間に隙間S6が第1外装部13の挿入孔12bに挿入された側面部17bのパイプ部17cによって設けられている。 Further, at this time, the side surface portion 17b of the second protective portion 17 is arranged between the first protective portion 16 and the first exterior portion 12, but the side surface portion 17b and the first exterior of the second protective portion 17 are arranged. A gap S6 is provided between the portion 12 and the pipe portion 17c of the side surface portion 17b inserted into the insertion hole 12b of the first exterior portion 13.

このため、第1保護部16が側方から衝撃を受けて、第1緩衝部18が弾性変形した際に、第2保護部17の側面部17bが第1保護部16によって押されても、第1外装部12に接触することがない。このため、これによってもサファイアガラス、セラミックなどの硬い脆性材料で形成された第1外装部12が破損することがない。 Therefore, even if the side surface portion 17b of the second protective portion 17 is pushed by the first protective portion 16 when the first protective portion 16 receives an impact from the side and the first buffer portion 18 is elastically deformed. It does not come into contact with the first exterior portion 12. Therefore, even with this, the first exterior portion 12 made of a hard brittle material such as sapphire glass or ceramic is not damaged.

また、例えば、腕時計ケース1が上方から衝撃を受けた際には、その衝撃を保護部材7の複数の第2保護部17で受け止めることができる。このときには、複数の第2保護部17は、上面部17aと側面部17bとを備えるので、複数の第2保護部17を撓らせて衝撃を受け止めることができ、複数の第2保護部17と外装部材6の第2外装部13との間にそれぞれ配置された緩衝部材14の第2緩衝部19によって衝撃が緩衝される。 Further, for example, when the wristwatch case 1 receives an impact from above, the impact can be received by a plurality of second protective portions 17 of the protective member 7. At this time, since the plurality of second protection portions 17 include the upper surface portion 17a and the side surface portions 17b, the plurality of second protection portions 17 can be bent to receive the impact, and the plurality of second protection portions 17 can be received. The impact is buffered by the second cushioning portion 19 of the cushioning member 14 arranged between the and the second exterior portion 13 of the exterior member 6.

すなわち、複数の第2緩衝部19も、第1緩衝部18と同様、硬度の異なる2種類の第1、第2緩衝層14a、14bを積層した構造で、第1緩衝層14aは硬度が30°〜50°程度の低硬度のシリコーンゴムであることにより、衝撃に応じて弾力的に変形して衝撃を吸収し、第2緩衝層14bは硬度が60°程度の高硬度で減衰率の防振用のシリコーンゴムであることにより、衝撃力を分散させて一点に集中させないようにすることができる。 That is, the plurality of second buffer portions 19 also have a structure in which two types of first and second buffer layers 14a and 14b having different hardness are laminated, like the first buffer portion 18, and the hardness of the first buffer layer 14a is 30. Since it is a low-hardness silicone rubber of about ° to 50 °, it elastically deforms in response to an impact to absorb the impact, and the second buffer layer 14b has a high hardness of about 60 ° and prevents attenuation. By using the silicone rubber for shaking, it is possible to disperse the impact force so that it is not concentrated at one point.

この場合、複数の第2保護部17と第2外装部13との間には、第2緩衝部19によって隙間S2がそれぞれ設けられているので、第2緩衝部19の第1緩衝層14aがその厚み方向に弾性変形しても、第2保護部16それぞれが第2外装部13に接触することがない。このため、第2外装部13がサファイア、ガラス、セラミックなどの硬い脆性材料で形成されていても破損することがない。 In this case, since the gap S2 is provided between the plurality of second protective portions 17 and the second exterior portion 13 by the second buffer portion 19, the first buffer layer 14a of the second buffer portion 19 is provided. Even if the second protective portion 16 is elastically deformed in the thickness direction, each of the second protective portions 16 does not come into contact with the second exterior portion 13. Therefore, even if the second exterior portion 13 is made of a hard brittle material such as sapphire, glass, or ceramic, it will not be damaged.

また、このときには、第2外装部13の外周部側の下面と第1外装部12の上面との間に第3緩衝部20が配置されていると共に、第2外装部13の内周部側の下面とケース本体5の上端面との間に第4緩衝部21が配置されている。このため、複数の第2保護部17が上方から衝撃を受けて、第2保護部17の上面部17aが第2外装部13を押し下げても、第3、第4緩衝部20、21によって緩衝することができる。 Further, at this time, the third cushioning portion 20 is arranged between the lower surface on the outer peripheral side of the second exterior portion 13 and the upper surface of the first exterior portion 12, and the inner peripheral portion side of the second exterior portion 13 is arranged. The fourth cushioning portion 21 is arranged between the lower surface of the case and the upper end surface of the case body 5. Therefore, even if the plurality of second protective portions 17 are impacted from above and the upper surface portion 17a of the second protective portion 17 pushes down the second exterior portion 13, the third and fourth buffer portions 20 and 21 buffer the surface. can do.

すなわち、第2外装部13の外周部側の下面と第1外装部12の上面との間に隙間S3が第3緩衝部20によって設けられていると共に、第2外装部13の内周部側の下面とケース本体5の上端面との間に隙間S4が第4緩衝部21によって設けられている。このため、複数の第2保護部17が上方から衝撃を受けて、第2保護部17の上面部17aが第2外装部13を押し下げても、第2外装部13が第1外装部12とケース本体5とに接触することがない。このため、これによってもサファイアガラス、セラミックなどの硬い脆性材料で形成された第1外装部12と第2外装部13とが破損することがない。 That is, a gap S3 is provided by the third cushioning portion 20 between the lower surface of the second exterior portion 13 on the outer peripheral portion side and the upper surface of the first exterior portion 12, and the inner peripheral portion side of the second exterior portion 13 is provided. A gap S4 is provided by the fourth cushioning portion 21 between the lower surface of the case and the upper end surface of the case body 5. Therefore, even if the plurality of second protective portions 17 receive an impact from above and the upper surface portion 17a of the second protective portion 17 pushes down the second exterior portion 13, the second exterior portion 13 becomes the first exterior portion 12. It does not come into contact with the case body 5. Therefore, even with this, the first exterior portion 12 and the second exterior portion 13 formed of a hard brittle material such as sapphire glass or ceramic are not damaged.

このように、この腕時計ケース1によれば、ケース本体5と、このケース本体5の外側に配置される脆性材料の外装部材6と、この外装部材6の外面に非接触状態で配置される保護部材7と、を備えていることにより、外装部材6が脆性材料であっても、ケース全体の耐衝撃性を確保することができると共に、ケース全体の小型化を図ることができる。 As described above, according to the wristwatch case 1, the case body 5, the brittle material exterior member 6 arranged on the outside of the case body 5, and the protection arranged on the outer surface of the exterior member 6 in a non-contact state.
