次に、このような腕時計ケース１の製造方法について説明する。
この腕時計ケース１の製造方法は、図２および図３に示すように、ケース本体１０の上部側外周に外装ケース１１を被せて配置する第１の工程と、ケース本体１０に外装ケース１１を結合部材１２によって固定する第２の工程と、外装ケース１１の外部に露出した結合部材１２を押え部材１７で押え付けた状態で、押え部材１７を裏蓋５で固定する第３の工程と、を備えている。 Next, a method of manufacturing such a wristwatch case 1 will be described.
As shown in FIGS. 2 and 3, the method for manufacturing the wristwatch case 1 includes a first step of covering the outer periphery of the upper portion of the case body 10 with the outer case 11 and arranging the outer case 11 on the case body 10. A second step of fixing by the member 12 and a third step of fixing the pressing member 17 with the back cover 5 while the connecting member 12 exposed to the outside of the outer case 11 is pressed by the pressing member 17. I have.

本実施形態の場合、第１の工程では、図３に示すように、ケース本体１０の上部側外周に外装ケース１１を上方から被せるように配置する。このときには、外装ケース１１に設けられた一対のカバー突起部２ｂをケース本体１０に設けられた一対の取付突起部２ａに対応させて、外装ケース１１をケース本体１０の上部側外周に配置する。 In the case of the present embodiment, in the first step, as shown in FIG. 3, the outer case 11 is arranged so as to cover the outer periphery on the upper side of the case body 10 from above. At this time, the outer case 11 is arranged on the upper outer circumference of the case body 10 so that the pair of cover protrusions 2b provided on the outer case 11 correspond to the pair of mounting protrusions 2a provided on the case body 10.

この状態では、ケース本体１０の１２時側と６時側とにおけるバンド取付部２の一対の取付突起部２ａ間に設けられた装着溝１３のうち、装着溝１３の上部側が外装ケース１１によって覆われ、装着溝１３の下部側が外装ケース１１によって覆われることがなく外装ケース１１の下側の外部に露出する。また、このときには、外装ケース１１の内周面に設けられた嵌合凹部１４をケース本体１０の装着溝１３の上部側に対応させる。 In this state, of the mounting grooves 13 provided between the pair of mounting protrusions 2a of the band mounting portions 2 on the 12 o'clock side and the 6 o'clock side of the case body 10, the upper side of the mounting grooves 13 is covered by the outer case 11. The lower side of the mounting groove 13 is not covered by the outer case 11 and is exposed to the outside of the lower side of the outer case 11. At this time, the fitting recess 14 provided on the inner peripheral surface of the outer case 11 is made to correspond to the upper side of the mounting groove 13 of the case body 10.

第２の工程では、図３に示すように、外装ケース１１の下側外部に露出した装着溝１３の下部側から結合部材１２を装着溝１３内に挿入させ、この装着溝１３および外装ケース１１の嵌合凹部１４に挿入された結合部材１２によって外装ケース１１をケース本体１０に固定する。このときには、まず、結合部材１２のフック部１６を外装ケース１１の下側外部に露出した装着溝１３の下部側から装着溝１３内に挿入させて、フック部１６の先端部を外装ケース１１の内周面に設けられた嵌合凹部１４に対応させる。 In the second step, as shown in FIG. 3, the coupling member 12 is inserted into the mounting groove 13 from the lower side of the mounting groove 13 exposed to the lower outside of the outer case 11, and the mounting groove 13 and the outer case 11 are inserted. The outer case 11 is fixed to the case body 10 by the coupling member 12 inserted into the fitting recess 14 of the above. At this time, first, the hook portion 16 of the coupling member 12 is inserted into the mounting groove 13 from the lower side of the mounting groove 13 exposed to the lower outside of the outer case 11, and the tip portion of the hook portion 16 is inserted into the mounting groove 13 of the outer case 11. Corresponds to the fitting recess 14 provided on the inner peripheral surface.

この状態で、本体部１５とフック部１６との境界部に設けられた円弧面１２ａを装着溝１３の円弧面１３ａに押し当てながら装着溝１３の円弧面１３ａに沿って摺動させる。すると、本体部１５がその円弧面１２ａを支点として回転しながら装着溝１３内に向けて移動して、フック部１６を外装ケース１１の嵌合凹部１４に徐々に挿入させる。 In this state, the arc surface 12a provided at the boundary between the main body portion 15 and the hook portion 16 is pressed against the arc surface 13a of the mounting groove 13 and slid along the arc surface 13a of the mounting groove 13. Then, the main body portion 15 moves toward the inside of the mounting groove 13 while rotating around the arc surface 12a as a fulcrum, and the hook portion 16 is gradually inserted into the fitting recess 14 of the outer case 11.

そして、本体部１５がその円弧面１２ａを支点として回転しながら装着溝１３内に挿入されて配置されると、フック部１６が嵌合凹部１４に嵌合する。これにより、外装ケース１１が結合部材１２によってケース本体１０の外周に確実にかつ強固に固定される。このように、外装ケース１１の下側外部に露出した装着溝１３の下部側から結合部材１２を装着溝１３内に挿入させるだけで、外装ケース１１がケース本体１０の外周に固定されるので、組立作業が簡単でかつ容易である。 Then, when the main body portion 15 is inserted and arranged in the mounting groove 13 while rotating with the arc surface 12a as a fulcrum, the hook portion 16 is fitted into the fitting recess 14. As a result, the outer case 11 is securely and firmly fixed to the outer periphery of the case body 10 by the coupling member 12. In this way, the outer case 11 is fixed to the outer periphery of the case body 10 simply by inserting the coupling member 12 into the mounting groove 13 from the lower side of the mounting groove 13 exposed to the lower outside of the outer case 11. The assembly work is simple and easy.

第３の工程では、図３に示すように、まず、外装ケース１１の下側外部に露出した結合部材１２の本体部１５を覆って押え部材１７を配置する。このときには、押え部材１７の両側に設けられた取付部１７ａの上部の係合突起１７ｂをケース本体１０の係合穴１１ａに差し込み、両側の取付部１７ａを装着溝１３の両側に位置するケース本体１０の外周面に設けられた取付溝１８に嵌め込む。これにより、外装ケース１１の下側外部に露出した結合部材１２の本体部１５が押え部材１７によって覆われて装着溝１３内に押え付けられる。 In the third step, as shown in FIG. 3, first, the pressing member 17 is arranged so as to cover the main body portion 15 of the connecting member 12 exposed to the lower outside of the outer case 11. At this time, the engaging protrusions 17b on the upper part of the mounting portions 17a provided on both sides of the pressing member 17 are inserted into the engaging holes 11a of the case body 10, and the mounting portions 17a on both sides are located on both sides of the mounting groove 13. It is fitted into the mounting groove 18 provided on the outer peripheral surface of the 10. As a result, the main body 15 of the coupling member 12 exposed to the lower outside of the outer case 11 is covered with the pressing member 17 and pressed into the mounting groove 13.

この状態で、ケース本体１０の下面に防水リング５ａを配置させると共に裏蓋５を配置させて、裏蓋５をビス５ｂによってケース本体１０に取り付ける。このときには、裏蓋５が押え部材１７の下端部を押し上げる。さらに、両側の取付部１７ａの上部に設けられた係合突起１７ｂがケース本体１０の係合穴１１ａに差し込まれているため、押え部材１７はケース本体１０に押し当てられる。これにより、押え部材１７は裏蓋５とケース本体１０の下端部との間に挟まれた状態でケース本体１０の外周面に取り付けられる。これにより、腕時計ケース１が簡単にかつ容易に組み立てられる。 In this state, the waterproof ring 5a is arranged on the lower surface of the case body 10 and the back cover 5 is arranged, and the back cover 5 is attached to the case body 10 by the screws 5b. At this time, the back cover 5 pushes up the lower end portion of the pressing member 17. Further, since the engaging protrusions 17b provided on the upper portions of the mounting portions 17a on both sides are inserted into the engaging holes 11a of the case body 10, the pressing member 17 is pressed against the case body 10. As a result, the pressing member 17 is attached to the outer peripheral surface of the case body 10 in a state of being sandwiched between the back cover 5 and the lower end portion of the case body 10. As a result, the wristwatch case 1 can be easily and easily assembled.

本実施形態の場合、ケース本体１０の下面に裏蓋５を取り付ける際には、予め、ケース本体１０内に時計モジュール６を組み込んで、複数の押釦スイッチ３をケース本体１０の外周にそれぞれ取り付ける。この状態で、ケース本体１０の下面に裏蓋５を取り付けて、腕時計ケース１を組み立てた際には、腕時計が組み立てられる。 In the case of the present embodiment, when the back cover 5 is attached to the lower surface of the case body 10, the watch module 6 is incorporated in the case body 10 in advance, and a plurality of push button switches 3 are attached to the outer periphery of the case body 10. In this state, when the back cover 5 is attached to the lower surface of the case body 10 and the wristwatch case 1 is assembled, the wristwatch is assembled.

このように、この腕時計の腕時計ケース１によれば、外周面に装着溝１３が上下方向に設けられたケース本体１０と、このケース本体１０の上部側外周に装着溝１３の下部側を露出させた状態で配置され、かつ装着溝１３の上部側に対応して嵌合凹部１４が設けられた外装ケース１１と、この外装ケース１１の外部に露出した装着溝１３の下部側から装着溝１３内に挿入されて、装着溝１３および外装ケース１１の嵌合凹部１４に配置されることにより、ケース本体１０に外装ケース１１を固定する結合部材１２と、を備えているので、組立作業性を向上させることができる。 As described above, according to the wristwatch case 1 of this wristwatch, the case main body 10 in which the mounting groove 13 is provided in the vertical direction on the outer peripheral surface and the lower side of the mounting groove 13 are exposed on the upper outer periphery of the case main body 10. The outer case 11 is arranged in a vertical state and has a fitting recess 14 corresponding to the upper side of the mounting groove 13, and the inside of the mounting groove 13 from the lower side of the mounting groove 13 exposed to the outside of the outer case 11. By being inserted into the mounting groove 13 and arranged in the fitting recess 14 of the outer case 11, the case main body 10 is provided with a connecting member 12 for fixing the outer case 11 to improve assembly workability. Can be made to.

また、例えば、特開平０７−２４４１７０号公報に記載された腕時計ケースでは、ケース本体の外周に結合部材を取り付ける際に、ケース本体の第１係合溝に結合部材の内側突起部を係合させ、外装ケースをケース本体の上方から結合部材の外周に嵌め込んで取り付ける際に、外装ケースの第２係合溝に結合部材の外側突起部を係合させる構造であるから、ケース本体に対して外装ケースを確実にかつ強固に取り付けることができない。 Further, for example, in the wristwatch case described in Japanese Patent Application Laid-Open No. 07-244170, when the coupling member is attached to the outer periphery of the case body, the inner protrusion of the coupling member is engaged with the first engaging groove of the case body. When the outer case is fitted and attached to the outer periphery of the coupling member from above the case body, the outer protrusion of the coupling member is engaged with the second engaging groove of the exterior case. The outer case cannot be attached securely and firmly.

すなわち、特開平０７−２４４１７０号公報に記載された腕腕時計ケースでは、ケース本体に対して外装ケースを確実にかつ強固に取り付けるために、ケース本体の係合溝と第１外装ケースの第２係合溝とを深く形成し、かつ結合部材の内側突起部と外側突起部とを長く突出させる必要があるが、結合部材の内側突起部と外側突起部とを長く突出させると、ケース本体の外周に結合部材を嵌め込むことができないばかりか、外装ケースをケース本体の上方から結合部材の外周に嵌め込むことができない。 That is, in the arm wristwatch case described in Japanese Patent Application Laid-Open No. 07-244170, in order to securely and firmly attach the outer case to the case main body, the engagement groove of the case main body and the second engagement of the first outer case It is necessary to form the joint groove deeply and to project the inner protrusion and the outer protrusion of the coupling member for a long time. However, if the inner protrusion and the outer protrusion of the coupling member are projected for a long time, the outer circumference of the case body is formed. Not only can the coupling member not be fitted into the case, but the outer case cannot be fitted into the outer periphery of the coupling member from above the case body.

このため、この腕時計ケースでは、結合部材の内側突起部と外側突起部との外部への突出長さをそれぞれ短くしなければならないため、ケース本体の第１係合溝に対する結合部材の内側突起部の係合と、外装ケースの第２係合溝に対する結合部材の外側突起部の係合とが浅くなり、ケース本体に対して外装ケースを強固に取り付けることができない。しかし、本実施形態はケース本体１０の上部側外周に外装ケース１１を被せた後に結合部材１２を挿入するため、結合部材１２と外装ケース１１との係合が浅くならず、ケース本体に対して外装ケースを強固に取り付けることができるようになる。 For this reason, in this wristwatch case, the outward protrusion lengths of the inner protrusion and the outer protrusion of the coupling member must be shortened, respectively, so that the inner protrusion of the coupling member with respect to the first engagement groove of the case body must be shortened. And the engagement of the outer protrusion of the coupling member with the second engagement groove of the outer case become shallow, and the outer case cannot be firmly attached to the case body. However, in the present embodiment, since the connecting member 12 is inserted after covering the outer peripheral portion on the upper side of the case body 10 with the outer case 11, the engagement between the connecting member 12 and the outer case 11 is not shallow, and the engagement with the case body is not shallow. The outer case can be firmly attached.

すなわち、この腕時計ケース１では、ケース本体１０の上部側外周に外装ケース１１を被せて配置させた際に、装着溝１３の下部側を外装ケース１１の下側外部に露出させることができると共に、外装ケース１１の嵌合凹部１４を装着溝１３の上部側に対応させることができ、これにより外装ケース１１の下側外部に露出した装着溝１３の下部側から結合部材１２を装着溝１３内に挿入させることができる。 That is, in this wristwatch case 1, when the outer peripheral case 11 is placed over the upper outer circumference of the case body 10, the lower side of the mounting groove 13 can be exposed to the lower outside of the outer case 11. The fitting recess 14 of the outer case 11 can be made to correspond to the upper side of the mounting groove 13, whereby the coupling member 12 can be inserted into the mounting groove 13 from the lower side of the mounting groove 13 exposed to the lower outside of the outer case 11. Can be inserted.

このため、この腕時計ケース１では、ケース本体１０の上部側外周に外装ケース１１を配置させた状態で、結合部材１２を装着溝１３内に挿入させることができるので、組立作業性が良いだけでなく、ケース本体１０の外面と外装ケース１１の内面との間の隙間を狭くすることができる。また、装着溝１３内に挿入された結合部材１２を外装ケース１１の嵌合凹部１４に嵌合させることができるので、ねじを用いずに結合部材１２によってケース本体１０に外装ケース１１を確実にかつ強固に固定することができる。 Therefore, in the wristwatch case 1, the coupling member 12 can be inserted into the mounting groove 13 with the outer case 11 arranged on the outer periphery of the upper portion of the case body 10, so that the assembly workability is only good. Instead, the gap between the outer surface of the case body 10 and the inner surface of the outer case 11 can be narrowed. Further, since the coupling member 12 inserted into the mounting groove 13 can be fitted into the fitting recess 14 of the outer case 11, the outer case 11 can be reliably attached to the case body 10 by the coupling member 12 without using screws. And it can be firmly fixed.

本実施形態の場合、結合部材１２は、ケース本体１０の上部側外周に外装ケース１１が配置された状態で、外装ケース１１の外部に露出した装着溝１３の下部側から装着溝１３内に挿入されて配置される本体部１５と、この本体部１５が装着溝１３内に配置された際に、外装ケース１１の嵌合凹部１４に嵌合するフック部１６と、を備えていることにより、外装ケース１１の下側外部に露出した装着溝１３の下部側から結合部材１２を装着溝１３内に挿入させた際に、フック部１６を外装ケース１１の嵌合凹部１４に確実に嵌合させることができると共に、本体部１５を装着溝１３内に確実に配置させることができる。 In the case of the present embodiment, the coupling member 12 is inserted into the mounting groove 13 from the lower side of the mounting groove 13 exposed to the outside of the outer case 11 in a state where the outer case 11 is arranged on the upper outer circumference of the case body 10. By providing a main body portion 15 to be arranged and a hook portion 16 to be fitted into the fitting recess 14 of the outer case 11 when the main body portion 15 is arranged in the mounting groove 13. When the coupling member 12 is inserted into the mounting groove 13 from the lower side of the mounting groove 13 exposed to the lower outside of the outer case 11, the hook portion 16 is securely fitted into the fitting recess 14 of the outer case 11. At the same time, the main body portion 15 can be reliably arranged in the mounting groove 13.

すなわち、この結合部材１２は、外装ケース１１の外部に露出した装着溝１３の下部側からフック部１６が装着溝１３に挿入されて外装ケース１１の嵌合凹部１４に対応した状態で、本体部１５が装着溝１３に挿入されて配置される際に、本体部１５がフック部１６側の端部を中心に回転しながらケース本体１０の装着溝１３内に挿入されて配置されると共にフック部１６が嵌合凹部１４に嵌合されることにより、外装ケース１１の外部に露出した装着溝１３の下部側から結合部材１２を円滑にかつ良好に挿入させて、フック部１６を外装ケース１１の嵌合凹部１４に確実に嵌合させることができると共に、本体部１５を装着溝１３内に確実に配置させることができる。 That is, the main body of the coupling member 12 is in a state where the hook portion 16 is inserted into the mounting groove 13 from the lower side of the mounting groove 13 exposed to the outside of the outer case 11 and corresponds to the fitting recess 14 of the outer case 11. When the 15 is inserted into the mounting groove 13 and arranged, the main body 15 is inserted and arranged in the mounting groove 13 of the case main body 10 while rotating around the end on the hook portion 16 side, and the hook portion is inserted. When the 16 is fitted into the fitting recess 14, the coupling member 12 is smoothly and satisfactorily inserted from the lower side of the mounting groove 13 exposed to the outside of the outer case 11, and the hook portion 16 is inserted into the outer case 11 of the outer case 11. It can be reliably fitted in the fitting recess 14, and the main body 15 can be reliably arranged in the mounting groove 13.

本実施形態の場合、結合部材１２は、本体部１５とフック部１６との境界部が円弧面１２ａに形成されていることにより、結合部材１２のフック部１６を外装ケース１１の下側外部に露出した装着溝１３の下部側から装着溝１３内に挿入させて、外装ケース１１の内周面に設けられた嵌合凹部１４に対応させた状態で、本体部１５とフック部１６との境界部に設けられた円弧面１２ａを装着溝１３の円弧面１３ａに押し当てながら装着溝１３の円弧面１３ａに沿って摺動させることができる。 In the case of the present embodiment, the coupling member 12 has the hook portion 16 of the coupling member 12 on the lower outside of the exterior case 11 because the boundary portion between the main body portion 15 and the hook portion 16 is formed on the arc surface 12a. The boundary between the main body portion 15 and the hook portion 16 in a state of being inserted into the mounting groove 13 from the lower side of the exposed mounting groove 13 and corresponding to the fitting recess 14 provided on the inner peripheral surface of the outer case 11. The arc surface 12a provided on the portion can be slid along the arc surface 13a of the mounting groove 13 while being pressed against the arc surface 13a of the mounting groove 13.

このため、この結合部材１２では、本体部１５の円弧面１２ａを支点として、本体部１５を装着溝１３内に向けて円滑に回転させながら移動させて、フック部１６を外装ケース１１の嵌合凹部１４に徐々に挿入させて嵌合させることができると共に、本体部１５を装着溝１３内に円滑に挿入させて良好に配置させることができる。 Therefore, in the coupling member 12, the main body portion 15 is smoothly rotated and moved toward the inside of the mounting groove 13 with the arc surface 12a of the main body portion 15 as a fulcrum, and the hook portion 16 is fitted to the outer case 11. It can be gradually inserted into the recess 14 to be fitted, and the main body portion 15 can be smoothly inserted into the mounting groove 13 and arranged satisfactorily.

また、この腕時計ケース１では、ケース本体１０の装着溝１３に配置されて外装ケース１１の外部に露出した結合部材１２の本体部１５を装着溝１３内に押え付ける押え部材１７を備えていることにより、外装ケース１１の外部に露出した装着溝１３から結合部材１２が脱落するのを押え部材１７によって確実に防ぐことができると共に、押え部材１７によって外装ケース１１の外部に露出した本体部１５を覆い隠すことができるので、外観的にもデザイン的に好ましいものを提供することができる。 Further, the wristwatch case 1 is provided with a pressing member 17 that is arranged in the mounting groove 13 of the case main body 10 and presses the main body portion 15 of the coupling member 12 exposed to the outside of the outer case 11 into the mounting groove 13.
