Description

この発明は、腕時計などの電子機器に用いられるケースの製造方法およびそれを含む時計の製造方法に関する。 The present invention relates to a method of manufacturing a case used for electronic equipment such as a wristwatch and a method of manufacturing a watch including the case.

例えば、腕時計ケースにおいては、特許文献１に記載されているように、ケース本体の外面に弾性カバー部材を設け、この弾性カバー部材でケース本体を保護する構造のものが知られている。 For example, in a wristwatch case, as described in Patent Document 1, there is known a structure in which an elastic cover member is provided on the outer surface of the case body and the case body is protected by the elastic cover member.

特開２０１０－３２４２４号公報JP 2010-32424 A

この種の腕時計ケースは、弾性カバー部材の３時側と９時側との各側部の中央部が外部側に突出して形成され、これら中央部の弾性カバー部材とこれに対応するケース本体との間に空間部を設け、この空間部によって弾性カバー部材を変形し易くする構造になっている。 In this type of wristwatch case, the central portions of the 3 o'clock and 9 o'clock side portions of the elastic cover member protrude outward. A space is provided between them, and this space facilitates deformation of the elastic cover member.

しかしながら、このような腕時計ケースでは、弾性カバー部材が外部から衝撃を受けた際に、３時側と９時側との衝撃を弾性カバー部材によって確実に吸収することができても、３時側および９時側以外の箇所の弾性カバー部材で衝撃を確実に吸収するためには、弾性カバー部材の肉厚を厚く形成しなければならないという問題がある。 However, in such a wristwatch case, when the elastic cover member receives an impact from the outside, the impact on the 3 o'clock side and the 9 o'clock side can be reliably absorbed by the elastic cover member. Also, in order to reliably absorb the impact with the elastic cover member at locations other than the 9 o'clock side, there is a problem that the thickness of the elastic cover member must be increased.

また、この腕時計ケースでは、弾性カバー部材の３時側と９時側との各側部の中央部を外部側に突出させ、これら中央部の弾性カバー部材とこれに対応するケース本体との間に空間部を設けているため、ケース全体の外形が大きくなり、ケース全体が大型化するという問題もある。 In this wristwatch case, the central portions of the 3 o'clock side and 9 o'clock side portions of the elastic cover member protrude outward, and the elastic cover member at the central portion and the corresponding case main body are arranged to extend outward. There is also a problem that the outer shape of the case as a whole becomes large because the space is provided in the case, and the size of the case as a whole becomes large.

この発明が解決しようとする課題は、外装部材が脆性材料であっても、ケース全体の耐衝撃性を確保し、かつ小型化を図ることができるケースの製造方法およびそれを含む時計の製造方法を提供することである。 The problem to be solved by the present invention is a method of manufacturing a case and a method of manufacturing a timepiece including the same, which can secure the impact resistance of the entire case and achieve miniaturization even if the exterior member is made of a brittle material. is to provide

これにより、一対の第１保護部１６が第１外装部１２と共にケース本体５に取り付けられる。このときには、第１外装部１２の外面と第１保護部１６の内面との間に第１緩衝部１８によって隙間Ｓ１が設けられる。また、このときには、筒部２４の軸方向の長さが第１外装部１２の貫通孔１２ｃの長さよりも長いので、第１保護部１６の内面と第１外装部１２の外面との間に隙間Ｓ１が設けられる。 As a result, the pair of first protective portions 16 are attached to the case body 5 together with the first exterior portion 12 . At this time, a gap S1 is provided by the first cushioning portion 18 between the outer surface of the first exterior portion 12 and the inner surface of the first protective portion 16 . Also, at this time, since the axial length of the cylindrical portion 24 is longer than the length of the through hole 12 c of the first exterior portion 12 , a gap between the inner surface of the first protection portion 16 and the outer surface of the first exterior portion 12 is maintained. A gap S1 is provided.

この場合、第１緩衝部１８は、第１外装部１２の外面と第１保護部１６の内面との間に隙間Ｓ１が設けられても、第１外装部１２の外面に設けられた凸部１２ａが第１保護部１６の内面に設けられた凹部１６ｃに配置されている．このため、第１緩衝部１８は、外部から見えることがない。これにより、腕時計ケース１が組み立てられる。 In this case, even if a gap S1 is provided between the outer surface of the first exterior portion 12 and the inner surface of the first protective portion 16, the first cushioning portion 18 does not prevent the convex portion provided on the outer surface of the first exterior portion 12 from 12a is arranged in a concave portion 16c provided on the inner surface of the first protective portion 16. As shown in FIG. Therefore, the first buffer portion 18 cannot be seen from the outside. Thus, the wristwatch case 1 is assembled.

このように腕時計ケース１が組み立てられた場合には、腕時計ケース１の２時が、４時側、８時側、および１０時側の各側部にスイッチ部４をそれぞれ取り付け、この状態で腕時計ケース１の内部に時計モジュール１１を下側から組み込む。そして、ケース本体５の下部に裏蓋１０を防水リング１０ａと共に取り付ける。これにより、腕時計が組み立てられる。 When the wristwatch case 1 is assembled in this way, the switch units 4 are attached to the 2 o'clock side, the 4 o'clock side, the 8 o'clock side, and the 10 o'clock side of the wristwatch case 1, respectively. A clock module 11 is assembled inside the case 1 from below. Then, the back cover 10 is attached to the lower part of the case body 5 together with the waterproof ring 10a. This completes the assembly of the watch.

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。 Such a wristwatch case 1 can be colored because the exterior member 6 is made of a material such as sapphire, glass, or ceramic, so that it is highly decorative and colorful. Since the exterior member 6 is exposed, a product with excellent design and high commercial value can be obtained. Further, in this wristwatch, even if the wristwatch case 1 receives an external impact, the impact is received by the protective member 7 so that the exterior member 6 made of a hard and 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 protection portion 16 of the protection member 7 . At this time, the impact is buffered by the first buffer portion 18 of the buffer member 14 partially arranged between the first protection 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 portion 18 has a structure in which two types of first and second buffer layers 14a and 14b having different hardnesses are laminated. Being made of rubber, it elastically deforms in response to an impact and absorbs the impact. It can disperse the impact force so that it is not concentrated at 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 by the first cushioning portion 18 between the first protection portion 16 and the first exterior portion 12, the first cushioning layer 14a of the first cushioning portion 18 extends in its thickness direction. Even if the first protective portion 16 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 part 12 is made of a hard and 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。 Also, at this time, the side surface portion 17b of the second protection portion 17 is arranged between the first protection portion 16 and the first exterior portion 12, and the side portion 17b of the second protection portion 17 and the first exterior A gap S6 is provided between the first exterior portion 12 and the pipe portion 17c of the side portion 17b inserted into the insertion hole 12b of the first exterior portion 13. As shown in FIG.

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 protection portion 17 is pushed by the first protection portion 16 when the first protection portion 16 receives an impact from the side and the first buffer portion 18 is elastically deformed, There is no contact with the first exterior part 12 . For this reason, the first exterior part 12 made of a hard and 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 the plurality of second protection portions 17 of the protection member 7 . At this time, since the plurality of second protection portions 17 are provided with the upper surface portion 17a and the side portion 17b, the plurality of second protection portions 17 can be deflected to receive the impact. and the second exterior portion 13 of the exterior member 6, the second cushioning portion 19 of the cushioning member 14, respectively, buffers the impact.

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 with different hardnesses are laminated, similar to the first buffer portion 18. The first buffer layer 14a has a hardness of 30 degrees. The second buffer layer 14b is made of silicone rubber with a low hardness of about 50° to elastically deform in response to an impact to absorb the impact. By using silicone rubber for vibration, it is possible to disperse the impact force and prevent it from concentrating on one point.
