Therefore, since bending strength of the spring bar 9 is sufficiently reinforced by the cylindrical member 21, the fitting strength of the watch band 24 to the band fitting part 6 is substantially increased by the cylindrical member 21 and the spring bar 9, and the rotation of the cylindrical member 21 with respect to the mounting hole 36 of the watch band 24 can be prevented.

Description

この発明は、部材同士を連結するための部材連結構造、バンド取付構造、およびこれらを備えた時計に関する。   The present invention relates to a member connection structure for connecting members together, a band mounting structure, and a timepiece including these.

例えば、腕時計においては、特許文献１に記載されているように、腕時計ケースに設けられたバンド取付部に、時計バンドの端部をばね棒によって取り付けるように構成された部材連結構造が知られている。   For example, in a wristwatch, as described in Patent Document 1, there is known a member connection structure configured to attach an end portion of a watch band to a band attaching portion provided in a watch case with a spring bar. Yes.

特開２００７−８９８８２号公報JP 2007-89882 A

このような部材連結構造であるバンド取付構造は、時計バンドの端部に取付孔が時計バンドの長手方向と直交する方向に設けられ、この時計バンドの端部を腕時計ケースのバンド取付部内に配置した際に、バンド取付部の両側部に設けられた一対の係止孔に時計バンドの端部に位置する取付孔の両端部が対応し、この取付孔内に配置されたばね棒の両端が一対の係止孔に挿入するように構成されている。   The band mounting structure, which is such a member connection structure, has a mounting hole at the end of the watch band in a direction perpendicular to the longitudinal direction of the watch band, and the end of the watch band is disposed in the band mounting portion of the watch case. In this case, both ends of the mounting hole located at the end of the watch band correspond to a pair of locking holes provided on both sides of the band mounting portion, and both ends of the spring rod disposed in the mounting hole are paired. It is comprised so that it may insert in the latching hole.

この場合、ばね棒は、時計バンドの取付孔内に挿入されるパイプ部と、このパイプ部の両側部内に出没可能に配置された一対のピン部材と、パイプ部内に配置されて一対のピン部材を押し出す方向に付勢するばね部材とを備えている。   In this case, the spring bar includes a pipe portion inserted into the attachment hole of the watch band, a pair of pin members disposed in both sides of the pipe portion, and a pair of pin members disposed in the pipe portion. And a spring member for biasing in the pushing direction.

これにより、このバンド取付構造は、時計バンドの端部の取付孔にばね棒のパイプ部を挿入させ、このばね棒の一対のピン部材をばね部材のばね力に抗してパイプ部内に押し込み、この状態で時計バンドの端部を腕時計ケースのバンド取付部内に配置した際に、ばね棒のばね部材のばね力によって、一対のピン部材を押し出してバンド取付部の一対の係止孔に挿入させることにより、腕時計ケースのバンド取付部に時計バンドを取り付けるように構成されている。   Thereby, this band mounting structure inserts the pipe part of the spring bar into the mounting hole at the end part of the watch band, and pushes the pair of pin members of the spring bar into the pipe part against the spring force of the spring member, In this state, when the end portion of the watch band is disposed in the band attaching portion of the watch case, the pair of pin members are pushed out by the spring force of the spring member of the spring bar and inserted into the pair of locking holes of the band attaching portion. Accordingly, the watch band is attached to the band attaching portion of the watch case.

しかしながら、このようなバンド取付構造では、腕時計ケースのバンド取付部に時計バンドをばね棒のみで取り付けているため、ばね棒にある程度の強度をもたせて、時計バンドの取付強度を確保しても、それ以上に取付強度を高めることができず、より一層、取付強度の高いバンド取付構造を提供することができないという問題がある。   However, in such a band attachment structure, since the watch band is attached to the watch case band attaching portion with only the spring bar, even if the spring bar has a certain degree of strength and the watch band is secured, There is a problem that the mounting strength cannot be further increased, and a band mounting structure with higher mounting strength cannot be provided.

この発明が解決しようとする課題は、取付強度を大幅に向上させることができる部材連結構造、バンド取付構造、および時計を提供することである。   The problem to be solved by the present invention is to provide a member connection structure, a band mounting structure, and a timepiece that can greatly improve the mounting strength.

この発明は、端部に取付孔が設けられた第１部材と、この第１部材の前記端部が配置され、かつ前記取付孔の両端部に対応する一対の係止孔を有する第２部材と、前記第１部材の前記取付孔に挿入され、かつ両端部が前記第２部材の前記一対の係止孔に係合する連結部材と、前記連結部材の外周に装着された筒状部材と、前記第１部材の前記取付孔に対する前記筒状部材の回転を阻止する回転防止部と、を備えていることを特徴とする部材連結構造である。   The present invention includes a first member having an attachment hole at an end thereof, and a second member having a pair of locking holes corresponding to both end portions of the attachment hole in which the end of the first member is disposed. A connecting member inserted into the mounting hole of the first member and having both end portions engaged with the pair of locking holes of the second member, and a cylindrical member mounted on the outer periphery of the connecting member And a rotation preventing portion for preventing rotation of the cylindrical member with respect to the mounting hole of the first member.

この発明によれば、筒状部材によって連結部材の曲げ強度を十分に補強することができるので、この筒状部材と連結部材とによって第１部材と第２部材との取付強度を大幅に向上させることができると共に、第１部材の取付孔に対する筒状部材の回転を防いで、筒状部材を一定の状態に位置規制することができる。   According to the present invention, since the bending strength of the connecting member can be sufficiently reinforced by the cylindrical member, the mounting strength between the first member and the second member is greatly improved by the cylindrical member and the connecting member. In addition, the cylindrical member can be prevented from rotating with respect to the mounting hole of the first member, and the position of the cylindrical member can be regulated in a certain state.

次に、このような腕時計のバンド取付構造の作用について説明する。
時計バンド７を腕時計ケース１に取り付ける場合には、まず、ばね棒９と筒状部材２１とを時計バンド７の取付駒１０の取付孔１６に挿入する。このときには、ばね棒９を筒状部材２１内に挿入させ、この筒状部材２１を取付駒１０の一対の駒部１３に設けられた取付孔１６に挿入し、この一対の駒部１３の切欠き部１３ａと筒状部材２１の切欠き部２１ａとを対応させる。 Next, the operation of such a wristwatch band mounting structure will be described.
When attaching the watch band 7 to the watch case 1, first, the spring bar 9 and the tubular member 21 are inserted into the attachment holes 16 of the attachment piece 10 of the watch band 7. At this time, the spring bar 9 is inserted into the cylindrical member 21, the cylindrical member 21 is inserted into the mounting holes 16 provided in the pair of piece parts 13 of the attachment piece 10, and the pair of piece parts 13 are cut. The notch part 13a and the notch part 21a of the cylindrical member 21 are made to correspond.

この状態では、取付駒１０の一対の駒部１３の取付孔１６内に配置された筒状部材２１の中間部が、取付駒１０の開口部１５から外部に露呈する。また、ばね棒９の一対のピン部材１９は、ばね棒９のコイルばね２０のばね力によってパイプ部１８から押し出されて、一対の駒部１３の取付孔１６から外部に突出する。さらに、このピン部材１９の操作突起１９ａは、一対の駒部１３の切欠き部１３ａと筒状部材２１の切欠き部２１ａとに対応して取付駒１０の下側に露呈する。   In this state, an intermediate portion of the cylindrical member 21 disposed in the attachment hole 16 of the pair of piece portions 13 of the attachment piece 10 is exposed to the outside from the opening 15 of the attachment piece 10. Further, the pair of pin members 19 of the spring bar 9 are pushed out of the pipe portion 18 by the spring force of the coil spring 20 of the spring bar 9 and project outside from the mounting holes 16 of the pair of piece portions 13. Further, the operation protrusion 19 a of the pin member 19 is exposed to the lower side of the mounting piece 10 corresponding to the notch 13 a of the pair of pieces 13 and the notch 21 a of the cylindrical member 21.

そして、時計バンド７を腕時計ケース１のバンド取付部６に取り付ける際には、まず、ばね棒９の一対のピン部材１９をコイルばね２０のばね力に抗してパイプ部１８内に押し込む。この状態で、時計バンド７の取付駒１０を腕時計ケース１のバンド取付部６における一対の取付突起部８間に配置し、ばね棒９の一対のピン部材１９を一対の取付突起部８の各係止孔１７に対応させる。   When the watch band 7 is attached to the band attaching portion 6 of the watch case 1, first, the pair of pin members 19 of the spring bar 9 are pushed into the pipe portion 18 against the spring force of the coil spring 20. In this state, the attachment piece 10 of the watch band 7 is arranged between the pair of attachment projections 8 in the band attachment portion 6 of the watch case 1, and the pair of pin members 19 of the spring bar 9 are arranged on each of the pair of attachment projections 8. It corresponds to the locking hole 17.

すると、一対のピン部材１９がコイルばね２０のばね力によってパイプ部１８内から押し出され、この押し出された一対のピン部材１９が一対の取付突起部８の各係止孔１７にそれぞれ挿入される。これにより、時計バンド７の取付駒１０が腕時計ケース１のバンド取付部６の一対の取付突起部８にばね棒９によって取り付けられ、時計バンド７が腕時計ケース１のバンド取付部６に取り付けられる。   Then, the pair of pin members 19 are pushed out from the inside of the pipe portion 18 by the spring force of the coil spring 20, and the pair of pushed pin members 19 are inserted into the respective locking holes 17 of the pair of attachment projections 8. . As a result, the attachment piece 10 of the watch band 7 is attached to the pair of attachment projections 8 of the band attachment portion 6 of the watch case 1 by the spring bar 9, and the watch band 7 is attached to the band attachment portion 6 of the watch case 1.

一方、時計バンド７を腕時計ケース１のバンド取付部６から取り外す場合には、一対の駒部１３の切欠き部１３ａと筒状部材２１の切欠き部２１ａとが対応した箇所にドライバーなどの工具（図示せず）を挿入して、ばね棒９の両端に位置する一対のピン部材１９の各操作突起１９ａをコイルばね２０のばね力に抗してパイプ部１８内に向けて移動させる。   On the other hand, when the watch band 7 is removed from the band attaching portion 6 of the watch case 1, a tool such as a screwdriver is provided at a position where the notch portion 13a of the pair of piece portions 13 and the notch portion 21a of the cylindrical member 21 correspond. (Not shown) is inserted, and the operation projections 19a of the pair of pin members 19 positioned at both ends of the spring bar 9 are moved toward the pipe portion 18 against the spring force of the coil spring 20.

すると、一対のピン部材１９が一対の取付突起部８の各係止孔１７から抜け出すので、時計バンド７の取付駒１０がバンド取付部６の一対の取付突起部８から取り外せる状態になる。これにより、時計バンド７を腕時計ケース１のバンド取付部６から取り外すことができる。   Then, the pair of pin members 19 come out from the respective locking holes 17 of the pair of attachment projections 8, so that the attachment piece 10 of the watch band 7 can be detached from the pair of attachment projections 8 of the band attachment portion 6. Thereby, the watch band 7 can be detached from the band attaching portion 6 of the watch case 1.

このように、この腕時計のバンド取付構造によれば、端部に位置する取付駒１０に取付孔１６が設けられた時計バンド７と、この時計バンド７の取付駒１０が配置され、かつ取付孔１６の両端部に対応する一対の係止孔１７を有するバンド取付部６と、時計バンド７の取付孔１６に挿入され、かつ両端部がバンド取付部６の一対の係止孔１７に係合するばね棒９と、カーボン繊維によって形成され、かつばね棒９の外周に装着された筒状部材２１とを備えているので、バンド取付部６に対する時計バンド７の取付強度を大幅に向上させることができる。   As described above, according to the wristband mounting structure of the wristwatch, the watch band 7 provided with the mounting hole 16 in the mounting piece 10 located at the end, the mounting piece 10 of the watch band 7 is disposed, and the mounting hole The band mounting portion 6 having a pair of locking holes 17 corresponding to both end portions of 16 and the mounting holes 16 of the watch band 7 are inserted into both ends, and both ends engage with the pair of locking holes 17 of the band mounting portion 6. Since the spring rod 9 and the cylindrical member 21 formed of carbon fiber and attached to the outer periphery of the spring rod 9 are provided, the attachment strength of the watch band 7 with respect to the band attachment portion 6 is greatly improved. Can do.

すなわち、このバンド取付構造では、カーボン繊維によって形成された筒状部材２１の内部にばね棒９のパイプ部１８が挿入されていることにより、筒状部材２１によってばね棒９の曲げ強度を十分に補強して高めることができるので、筒状部材２１およびばね棒９によって腕時計ケース１のバンド取付部６に対する時計バンド７の取付強度を大幅に向上させることができる。   That is, in this band mounting structure, the pipe member 18 of the spring bar 9 is inserted into the cylindrical member 21 formed of carbon fiber, so that the bending strength of the spring bar 9 is sufficiently increased by the cylindrical member 21. Since it can be reinforced and enhanced, the attachment strength of the watch band 7 to the band attachment portion 6 of the watch case 1 can be greatly improved by the tubular member 21 and the spring bar 9.

この場合、筒状部材２１は、カーボン繊維によって形成されていることにより、強度が極めて高く、ばね棒９を十分に補強してばね棒９の曲げ強度を確実に高めることができるほか、重さが軽いため、筒状部材２１の外径が大きくても、ばね棒９および筒状部材２１全体の重量の増加を大幅に抑えることができる。   In this case, since the cylindrical member 21 is formed of carbon fiber, the strength is extremely high, and the spring rod 9 can be sufficiently reinforced to increase the bending strength of the spring rod 9 reliably. Therefore, even if the outer diameter of the cylindrical member 21 is large, an increase in the weight of the spring bar 9 and the entire cylindrical member 21 can be significantly suppressed.

また、時計バンド７の取付駒１０には、筒状部材２１を露呈させるための開口部１５が設けられていることにより、この開口部１５を通して筒状部材２１を外部から見ることができるので、ばね棒９よりも太い筒状部材２１によって強度的な安心感を与えることができ、これにより商品質感を向上させることができると共に、デザイン的にも好ましいものを提供することができる。   Further, since the mounting piece 10 of the watch band 7 is provided with an opening 15 for exposing the cylindrical member 21, the cylindrical member 21 can be seen from the outside through the opening 15. The cylindrical member 21 that is thicker than the spring bar 9 can give a strong sense of security, thereby improving the product texture and providing a product that is preferable in terms of design.

また、このバンド取付構造では、ばね棒１９が、筒状部材２１内に配置されるパイプ部１８と、このパイプ部１８の両端部に出没可能に挿入された一対のピン部材１９と、パイプ部１８内に配置されて一対のピン部材１９を押し出す方向に付勢するコイルばね２０とを備えた構成であるから、時計バンド７を腕時計ケース１のバンド取付部８に簡単にかつ確実に取り付けることができる。   Further, in this band mounting structure, the spring bar 19 includes a pipe portion 18 disposed in the cylindrical member 21, a pair of pin members 19 inserted in both ends of the pipe portion 18 so as to be able to protrude and retract, and a pipe portion. Since the coil spring 20 is disposed in the coil 18 and urges the pair of pin members 19 in the pushing direction, the watch band 7 can be easily and securely attached to the band attaching portion 8 of the watch case 1. Can do.

この場合、ばね棒９は、コイルばね２０のばね力によってピン部材１９がパイプ部１８から押し出されてバンド取付部８の係止孔１７に挿入した際に、筒状部材２１の両端部に設けられた切欠き部２１ａと、時計バンド７の取付駒１０の両端部に設けられた切欠き部１３ａとが対応して、ばね棒９のピン部材１９を露呈させることができる。   In this case, the spring bar 9 is provided at both ends of the cylindrical member 21 when the pin member 19 is pushed out of the pipe portion 18 by the spring force of the coil spring 20 and inserted into the locking hole 17 of the band attachment portion 8. The cut-out portion 21a and the cut-out portions 13a provided at both ends of the mounting piece 10 of the watch band 7 correspond to each other so that the pin member 19 of the spring bar 9 can be exposed.

このため、筒状部材２１の切欠き部２１ａと時計バンド７の取付駒１０の切欠き部１３ａとが対応した箇所にドライバーなどの工具を挿入して、ばね棒９のピン部材１９をパイプ部１８内に向けて押し込むように操作することができるので、コイルばね２０のばね力によってバンド取付部６の一対の係止孔１７に挿入しているピン部材１９を係止孔１７から抜き出すことができ、これにより時計バンド７をバンド取付部６から容易に取り外して、簡単に交換することができる。   For this reason, a tool such as a screwdriver is inserted into a location where the notch 21a of the cylindrical member 21 and the notch 13a of the mounting piece 10 of the watch band 7 correspond to each other, and the pin member 19 of the spring bar 9 is connected to the pipe part. The pin member 19 inserted into the pair of locking holes 17 of the band attaching portion 6 can be extracted from the locking hole 17 by the spring force of the coil spring 20. Thus, the watch band 7 can be easily removed from the band attaching portion 6 and easily replaced.

Then, a plurality of inner peripheral protrusions 33 provided on the inner peripheral surface of the auxiliary cylinder part 30 are elastically pressed against the outer peripheral surface of the cylindrical member 21 and a plurality of outer peripheral surfaces of the auxiliary cylinder part 30 are provided. The outer peripheral projection 32 is elastically pressed against the inner peripheral surface of the mounting hole 31 of the mounting piece 10. Thereby, the cylindrical member 21 is fixed to the mounting piece 10.

また、このときには、一対の駒部１３の切欠き部１３ａと補助筒部３０の切欠き部３４とが対応する。これにより、ばね棒９の一対のピン部材１９は、ばね棒９のコイルばね２０のばね力によってパイプ部１８から押し出されて、一対の駒部１３の取付孔３１から外部に突出する。   At this time, the notch portion 13a of the pair of piece portions 13 and the notch portion 34 of the auxiliary cylinder portion 30 correspond to each other. As a result, the pair of pin members 19 of the spring bar 9 are pushed out of the pipe part 18 by the spring force of the coil spring 20 of the spring bar 9 and project outside from the mounting holes 31 of the pair of piece parts 13.

この状態では、第１実施形態と同様、取付駒１０の一対の駒部１３の取付孔３１内に配置された筒状部材２１の中間部が、一対の駒部１３の開口部１５から外部に露呈する。また、このピン部材１９の操作突起１９ａは、一対の駒部１３の切欠き部１３ａと補助筒部３０の切欠き部３４とに対応して取付駒１０の下側に露呈する。   In this state, as in the first embodiment, the intermediate part of the cylindrical member 21 disposed in the attachment hole 31 of the pair of piece parts 13 of the attachment piece 10 is exposed to the outside from the opening 15 of the pair of piece parts 13.

Accordingly, the operation protrusion 19 a of the pin member 19 is exposed to the lower side of the pair of band end portions 26 through the notch portion 29 of the band end portion 26 and the notch portion 37 of the cover member 35.

そして、時計バンド２４の一端部を腕時計ケース１のバンド取付部６に取り付ける際には、第２実施形態と同様、まず、ばね棒９の一対のピン部材１９をコイルばね２０のばね力に抗してパイプ部１８内に押し込む。この状態で、時計バンド２４の一端部に位置する一対のバンド端部２６を腕時計ケース１のバンド取付部６における一対の取付突起部８間に配置し、一対のピン部材１９を一対の取付突起部８の各係止孔１７に対応させる。   When attaching one end portion of the watch band 24 to the band attaching portion 6 of the watch case 1, first, the pair of pin members 19 of the spring bar 9 are resisted against the spring force of the coil spring 20 as in the second embodiment. Then, it is pushed into the pipe portion 18. In this state, a pair of band end portions 26 located at one end portion of the watch band 24 are disposed between the pair of mounting projections 8 in the band mounting portion 6 of the watch case 1, and the pair of pin members 19 are paired with the pair of mounting projections. It corresponds to each locking hole 17 of the part 8.

すると、第２実施形態と同様、一対のピン部材１９がコイルばね２０のばね力によってパイプ部１８内から押し出され、この押し出された一対のピン部材１９が一対の取付突起部８の各係止孔１７にそれぞれ挿入される。これにより、時計バンド２４の一対のバンド端部２６が腕時計ケース１のバンド取付部６の一対の取付突起部８にばね棒９によって取り付けられ、時計バンド２４が腕時計ケース１のバンド取付部６に取り付けられる。   Then, as in the second embodiment, the pair of pin members 19 are pushed out from the inside of the pipe portion 18 by the spring force of the coil spring 20, and the pair of pushed pin members 19 are locked to the pair of mounting projections 8. Each is inserted into the hole 17. As a result, the pair of band end portions 26 of the watch band 24 are attached to the pair of attachment projections 8 of the band attachment portion 6 of the watch case 1 by the spring bar 9, and the watch band 24 is attached to the band attachment portion 6 of the watch case 1.

一方、時計バンド２４を腕時計ケース１のバンド取付部６から取り外す場合には、時計バンド２４の一端部に位置する一対のバンド端部２６の各切欠き部２９およびカバー部材３５の切欠き部３７が対応した箇所に、ドライバーなどの工具（図示せず）を挿入して、ばね棒９の両端に位置する一対のピン部材１９の各操作突起１９ａを、コイルばね２０のばね力に抗してパイプ部１８内に向けて移動させる。   On the other hand, when the watch band 24 is removed from the band attaching portion 6 of the watch case 1, each notch portion 29 of the pair of band end portions 26 positioned at one end portion of the watch band 24 and the notch portion 37 of the cover member 35. A tool such as a screwdriver (not shown) is inserted into the position corresponding to, and the operation protrusions 19a of the pair of pin members 19 positioned at both ends of the spring bar 9 are resisted against the spring force of the coil spring 20. It moves toward the pipe part 18.

すると、第２実施形態と同様、一対のピン部材１９が一対の取付突起部８の各係止孔１７から抜け出すので、時計バンド２４の一対のバンド端部２６がバンド取付部６の一対の取付突起部８から取り外せる状態になる。これにより、時計バンド２４を腕時計ケース１のバンド取付部６から取り外すことができる。   Then, as in the second embodiment, the pair of pin members 19 come out from the respective locking holes 17 of the pair of attachment projections 8, so that the pair of band end portions 26 of the watch band 24 is attached to the pair of attachments of the band attachment portion 6. It will be in the state which can be removed from the projection part 8. FIG. Thereby, the watch band 24 can be detached from the band attaching portion 6 of the watch case 1.

このように、この腕時計のバンド取付構造によれば、第２実施形態と同様の作用効果があるほか、カーボン繊維からなる筒状部材２１の外周面を軟質の合成樹脂からなるカバー部材３５で覆った構成であるから、カバー部材３５によって筒状部材２１を保護することができると共に、カバー部材３５が外部から衝撃を受けた際に、その衝撃が筒状部材２１に伝わないように緩衝することができ、これにより筒状部材２１の傷付きによるカーボン繊維の散乱を確実にかつ良好に防ぐことができる。   As described above, according to the wristband mounting structure of the wristwatch, the same effect as that of the second embodiment is obtained, and the outer peripheral surface of the cylindrical member 21 made of carbon fiber is covered with the cover member 35 made of soft synthetic resin. Therefore, the cylindrical member 21 can be protected by the cover member 35 and buffered so that the impact is not transmitted to the cylindrical member 21 when the cover member 35 receives an impact from outside. Thus, scattering of the carbon fiber due to the scratch of the cylindrical member 21 can be reliably and satisfactorily prevented.

When the cylindrical member 21 is stored and assembled, it is possible to reliably and well prevent the cylindrical member 21 from being damaged and the carbon fibers from being scattered.

また、カバー部材３５は、その両端部がバンド取付部６の一対の取付突起部８の各内端面に弾力的に当接しているので、このカバー部材３５を軸方向にガタツクことがなく位置規制することができ、これにより筒状部材２１の軸方向の位置も確実にかつ良好に位置規制することがきる。   Further, since both end portions of the cover member 35 are elastically in contact with the inner end surfaces of the pair of attachment projections 8 of the band attachment portion 6, the position of the cover member 35 is not restricted in the axial direction. Thus, the position of the cylindrical member 21 in the axial direction can be reliably and satisfactorily regulated.

また、このカバー部材３５の外周面には、一対のバンド端部２６に設けられた取付孔３６の内周面に弾力的に圧接する複数の突起部３８が円周方向に沿って設けられているので、この複数の突起部３８によってカバー部材３５を一対のバンド端部２６に確実に固定することができると共に、カバー部材３５および筒状部材２１の軸方向および径方向へのガタツキを確実にかつ良好に防ぐことができる。   In addition, a plurality of protrusions 38 are provided along the circumferential direction on the outer peripheral surface of the cover member 35 so as to be elastically pressed against the inner peripheral surfaces of the mounting holes 36 provided in the pair of band end portions 26. Accordingly, the cover member 35 can be securely fixed to the pair of band end portions 26 by the plurality of protrusions 38 and the backlash in the axial direction and the radial direction of the cover member 35 and the cylindrical member 21 can be reliably ensured. And it can prevent well.

さらに、このカバー部材３５は、透明または半透明の合成樹脂によって形成されているので、時計バンド２４の端部に位置する一対のバンド端部２６間にカバー部材３５が配置された際、および時計バンド２４が腕時計ケース１のバンド取付部６に取り付けられた際に、カバー部材３５の中間部が一対のバンド端部２６間に位置する開口部２５から外部に露呈し、この露呈したカバー部材３５を通して筒状部材２１を見えることができると共に、カバー部材３５が光学的なレンズとして機能するので、筒状部材２１を大きく見せることができる。   Further, since the cover member 35 is formed of a transparent or translucent synthetic resin, when the cover member 35 is disposed between the pair of band end portions 26 positioned at the end portions of the watch band 24, and the watch When the band 24 is attached to the band attaching portion 6 of the wristwatch case 1, the intermediate portion of the cover member 35 is exposed to the outside through the opening 25 located between the pair of band end portions 26, and the exposed cover member 35 is exposed. The cylindrical member 21 can be seen through, and the cover member 35 functions as an optical lens, so that the cylindrical member 21 can be shown larger.

次に、このような腕時計のバンド取付構造の作用について説明する。
時計バンド７を腕時計ケース１に取り付ける場合には、まず、ばね棒９、筒状部材２１、およびカバー部材４０を時計バンド７の取付駒１０の取付孔４１に挿入する。このときには、ばね棒９を筒状部材２１内に挿入させ、この筒状部材２１をカバー部材４０と共に取付駒１０の一対の駒部１３の取付孔４１に挿入し、この一対の駒部１３の切欠き部１３ａとカバー部材４０の切欠き部４２とを対応させる。 Next, the operation of such a wristwatch band mounting structure will be described.
When attaching the watch band 7 to the watch case 1, first, the spring bar 9, the cylindrical member 21, and the cover member 40 are inserted into the attachment holes 41 of the attachment piece 10 of the watch band 7. At this time, the spring bar 9 is inserted into the cylindrical member 21, and the cylindrical member 21 is inserted into the mounting hole 41 of the pair of piece portions 13 of the attachment piece 10 together with the cover member 40. The notch part 13a and the notch part 42 of the cover member 40 are made to correspond.

この状態では、取付駒１０の一対の駒部１３の取付孔４１内に配置されたカバー部材４０の中間部が、一対の駒部１３の開口部１５から外部に露呈し、このカバー部材４０を通して筒状部材２１の中間部が見える。また、ばね棒９の一対のピン部材１９は、ばね棒９のコイルばね２０のばね力によってパイプ部１８から押し出されて、一対の駒部１３の取付孔４１から外部に突出する。さらに、このピン部材１９の操作突起１９ａは、一対の駒部１３の切欠き部１３ａとカバー部材４０の切欠き部４２とに対応して取付駒１０の下側に露呈する。   In this state, the intermediate part of the cover member 40 disposed in the attachment hole 41 of the pair of piece parts 13 of the attachment piece 10 is exposed to the outside from the opening 15 of the pair of piece parts 13 and passes through the cover member 40. The middle part of the cylindrical member 21 can be seen. The pair of pin members 19 of the spring bar 9 is pushed out of the pipe part 18 by the spring force of the coil spring 20 of the spring bar 9 and protrudes outside from the mounting holes 41 of the pair of piece parts 13. Further, the operation protrusion 19 a of the pin member 19 is exposed to the lower side of the mounting piece 10 corresponding to the notch 13 a of the pair of pieces 13 and the notch 42 of the cover member 40.

そして、時計バンド７を腕時計ケース１のバンド取付部６に取り付ける際には、第１実施形態と同様、まず、ばね棒９の一対のピン部材１９をコイルばね２０のばね力に抗してパイプ部１８内に押し込む。この状態で、時計バンド７の取付駒１０を腕時計ケース１のバンド取付部６における一対の取付突起部８間に配置し、一対のピン部材１９を一対の取付突起部８の各係止孔１７に対応させる。   When the watch band 7 is attached to the band attaching portion 6 of the watch case 1, first, the pair of pin members 19 of the spring bar 9 are piped against the spring force of the coil spring 20 as in the first embodiment. Push into part 18. In this state, the attachment piece 10 of the watch band 7 is disposed between the pair of attachment projections 8 in the band attachment portion 6 of the watch case 1, and the pair of pin members 19 are respectively engaged with the locking holes 17 of the pair of attachment projections 8. To correspond to.

すると、一対のピン部材１９がコイルばね２０のばね力によってパイプ部１８内から押し出され、この押し出された一対のピン部材１９が一対の取付突起部８の各係止孔１７にそれぞれ挿入される。これにより、時計バンド７の取付駒１０が腕時計ケース１のバンド取付部６の一対の取付突起部８にばね棒９によって取り付けられ、時計バンド７が腕時計ケース１のバンド取付部６に取り付けられる。   Then, the pair of pin members 19 are pushed out from the inside of the pipe portion 18 by the spring force of the coil spring 20, and the pair of pushed pin members 19 are inserted into the respective locking holes 17 of the pair of attachment projections 8. . As a result, the attachment piece 10 of the watch band 7 is attached to the pair of attachment projections 8 of the band attachment portion 6 of the watch case 1 by the spring bar 9, and the watch band 7 is attached to the band attachment portion 6 of the watch case 1.

一方、時計バンド７を腕時計ケース１のバンド取付部６から取り外す場合には、一対の駒部１３の切欠き部１３ａとカバー部材４０の切欠き部４２とが対応した箇所にドライバーなどの工具（図示せず）を挿入して、ばね棒９の両端に位置する一対のピン部材１９の各操作突起１９ａをコイルばね２０のばね力に抗してパイプ部１８内に向けて移動させる。   On the other hand, when the watch band 7 is removed from the band attaching portion 6 of the watch case 1, a tool (such as a screwdriver) is provided at a position where the notch portion 13a of the pair of piece portions 13 and the notch portion 42 of the cover member 40 correspond. (Not shown) is inserted, and the operation projections 19a of the pair of pin members 19 positioned at both ends of the spring bar 9 are moved toward the pipe portion 18 against the spring force of the coil spring 20.

すると、一対のピン部材１９が一対の取付突起部８の各係止孔１７から抜け出すので、第１実施形態と同様、時計バンド７の取付駒１０がバンド取付部６の一対の取付突起部８から取り外せる状態になる。これにより、時計バンド７を腕時計ケース１のバンド取付部６から取り外すことができる。   Then, since the pair of pin members 19 comes out from the respective locking holes 17 of the pair of attachment projections 8, the attachment piece 10 of the watch band 7 is paired with the pair of attachment projections 8 of the band attachment portion 6 as in the first embodiment. It can be removed from. Thereby, the watch band 7 can be detached from the band attaching portion 6 of the watch case 1.

このように、この腕時計のバンド取付構造によれば、第１実施形態と同様の作用効果があるほか、カーボン繊維からなる筒状部材２１の外周面を軟質の合成樹脂からなるカバー部材４０で覆った構成であるから、第４実施形態と同様、カバー部材４０によって筒状部材２１を保護することができると共に、カバー部材４０が外部から衝撃を受けた際に、その衝撃が筒状部材２１に伝わないように緩衝することができ、これにより筒状部材２１の傷付きによるカーボン繊維の散乱を確実にかつ良好に防ぐことができる。   As described above, according to the wristband mounting structure of the wrist watch, the same effect as that of the first embodiment is obtained, and the outer peripheral surface of the cylindrical member 21 made of carbon fiber is covered with the cover member 40 made of soft synthetic resin. Therefore, as in the fourth embodiment, the cylindrical member 21 can be protected by the cover member 40, and when the cover member 40 receives an impact from the outside, the impact is applied to the cylindrical member 21. It can buffer so that it may not be transmitted, and, thereby, the scattering of the carbon fiber by the damage of the cylindrical member 21 can be prevented reliably and favorably.

この場合にも、このカバー部材４０は、筒状部材２１の外周面にインサート成形によって一体に形成することにより、第４実施形態と同様、簡単にかつ容易にカバー部材４０を筒状部材２１の外周面に設けることができると共に、筒状部材２１の保管時および組み付け時に筒状部材２１が傷付いてカーボン繊維が散乱するのを確実にかつ良好に防ぐことができる。   Also in this case, the cover member 40 is formed integrally with the outer peripheral surface of the cylindrical member 21 by insert molding, so that the cover member 40 can be easily and easily attached to the cylindrical member 21 as in the fourth embodiment. While being able to be provided on the outer peripheral surface, it is possible to reliably and satisfactorily prevent the carbon member from being scattered due to the cylindrical member 21 being damaged when the cylindrical member 21 is stored and assembled.

また、カバー部材４０は、その両端部がバンド取付部６の一対の取付突起部８の各内端面に弾力的に当接しているので、このカバー部材３５を軸方向にガタツクことがなく位置規制することができ、これにより筒状部材２１の軸方向の位置も確実にかつ良好に位置規制することがきる。   Further, since both end portions of the cover member 40 are elastically in contact with the inner end surfaces of the pair of mounting projections 8 of the band mounting portion 6, the position of the cover member 35 is not restricted in the axial direction. Thus, the position of the cylindrical member 21 in the axial direction can be reliably and satisfactorily regulated.

また、このカバー部材４０の外周面には、取付駒１０の一対の駒部１３に設けられた取付孔４１の内周面に弾力的に圧接触する複数の突起部４３が円周方向に沿って設けられているので、この複数の突起部４３によってカバー部材４０を一対の駒部１３に確実に固定することができると共に、カバー部材４０および筒状部材２１の軸方向および径方向へのガタツキを確実にかつ良好に防ぐことができる。   Further, on the outer peripheral surface of the cover member 40, a plurality of protrusions 43 that are in elastic pressure contact with the inner peripheral surface of the mounting hole 41 provided in the pair of piece portions 13 of the mounting piece 10 are arranged along the circumferential direction. Accordingly, the cover member 40 can be securely fixed to the pair of pieces 13 by the plurality of projections 43, and the cover member 40 and the cylindrical member 21 are loose in the axial direction and the radial direction.

Next, a sixth embodiment in which the present invention is applied to a wristwatch will be described with reference to FIGS. In this case, the same parts as those in the fifth embodiment shown in FIGS.
As shown in FIGS. 23 to 26, the wristwatch has a configuration in which both end portions of the cover member 45 are bitten into the band attaching portion 6 of the wristwatch case 1, and the other configuration is substantially the same as that of the fifth embodiment. ing.

すなわち、カバー部材４５は、第５実施形態と同様、ウレタン樹脂、シリコーン樹脂などのエラストマー樹脂の透明または半透明の軟質の合成樹脂からなり、図２５および図２７に示すように、カーボン繊維からなる筒状部材２１の外周面にインサート成形によって一体に形成されている。このカバー部材４５は、その軸方向の長さが、金属製の時計バンド７の長手方向と直交する方向の取付駒１０の長さよりも長く形成されている。   That is, the cover member 45 is made of a transparent or translucent soft synthetic resin of an elastomer resin such as urethane resin or silicone resin, as in the fifth embodiment, and is made of carbon fiber as shown in FIGS. The cylindrical member 21 is integrally formed on the outer peripheral surface by insert molding. The cover member 45 is formed such that its axial length is longer than the length of the mounting piece 10 in the direction perpendicular to the longitudinal direction of the metal watch band 7.

この場合、腕時計ケース１のバンド取付部６における一対の取付突起部８には、第５実施形態と同様、ばね棒９のピン部材１９が挿入する各係止孔１７が時計バンド７の取付駒１０の取付孔４１に対応して設けられている。また、一対の取付突起部８の内端面には、図２４〜図２６に示すように、カバー部材４５の両端部が挿入する切欠き凹部４６がそれぞれ設けられている。   In this case, each of the pair of mounting projections 8 in the band mounting portion 6 of the wristwatch case 1 is provided with a locking hole 17 into which the pin member 19 of the spring bar 9 is inserted, as in the fifth embodiment. 10 attachment holes 41 are provided. Further, as shown in FIGS. 24 to 26, notch concave portions 46 into which both end portions of the cover member 45 are inserted are provided on the inner end surfaces of the pair of attachment projections 8, respectively.

この切欠き凹部４６は、図２５および図２６に示すように、一対の取付突起部８の係止孔１７を中心とする半円弧状の部分から一対の取付突起部８の下端部に亘って形成されている。これにより、カバー部材４５は、その両端部が一対の取付突起部８の下側から各切欠き凹部４６内に挿入して、一対の取付突起部８の各係止孔１７に対応するように構成されている。   As shown in FIGS. 25 and 26, the notch recess 46 extends from a semicircular arc-shaped portion centering on the locking hole 17 of the pair of mounting projections 8 to the lower end of the pair of mounting projections 8. Is formed. As a result, the cover member 45 is inserted into the notch recesses 46 from the lower sides of the pair of attachment projections 8 so that both ends thereof correspond to the locking holes 17 of the pair of attachment projections 8. It is configured.

ところで、カバー部材４５の外周面には、図２７に示すように、時計バンド７の取付駒１０に設けられた取付孔４１の内周面に弾力的に圧接する複数の突起部４３が円周方向に沿って設けられている。また、このカバー部材４５の両端部には、ばね棒９のピン部材１９の操作突起１９ａを操作するための切欠き部４７が下側に開放されて設けられている。   Incidentally, on the outer peripheral surface of the cover member 45, as shown in FIG. 27, a plurality of protrusions 43 that are elastically pressed against the inner peripheral surface of the mounting hole 41 provided in the mounting piece 10 of the watch band 7 are circumferential. It is provided along the direction. Further, notches 47 for operating the operation projections 19a of the pin member 19 of the spring bar 9 are provided at both ends of the cover member 45 so as to open downward.

この場合、筒状部材２１は、図２５に示すように、その軸方向の長さがばね棒９のパイプ部１８の長さよりも長く、カバー部材４５の長さよりも短く形成され、筒状部材２１の両端部がカバー部材４５の切欠き部４７内に少し挿入する長さに形成されている。これにより、筒状部材２１は、時計バンド７が腕時計ケース１のバンド取付部６に取り付けられた際に、両端部がバンド取付部６の切欠き凹部４６内に挿入するように構成されている。   In this case, as shown in FIG. 25, the cylindrical member 21 is formed such that its axial length is longer than the length of the pipe portion 18 of the spring bar 9 and shorter than the length of the cover member 45. Both end portions of 21 are formed so as to be slightly inserted into the cutout portion 47 of the cover member 45. Thereby, the cylindrical member 21 is configured such that both ends are inserted into the notch recesses 46 of the band attaching portion 6 when the watch band 7 is attached to the band attaching portion 6 of the watch case 1. .

次に、このような腕時計のバンド取付構造の作用について説明する。
時計バンド７を腕時計ケース１に取り付ける場合には、第５実施形態と同様、ばね棒９を筒状部材２１内に挿入させ、この筒状部材２１をカバー部材４５と共に取付駒１０の一対の駒部１３の両側に位置する一対の駒部１３に設けられた取付孔４１に挿入し、この一対の駒部１３の切欠き部１３ａとカバー部材４５の切欠き部４７とを対応させる。 Next, the operation of such a wristwatch band mounting structure will be described.
When attaching the watch band 7 to the watch case 1, as in the fifth embodiment, the spring bar 9 is inserted into the cylindrical member 21, and the cylindrical member 21 together with the cover member 45 is paired with the pair of attachment pieces 10. It inserts in the attachment hole 41 provided in a pair of piece part 13 located in the both sides of the part 13, and the notch part 13a of this pair of piece part 13 and the notch part 47 of the cover member 45 are matched.

この状態では、取付駒１０の一対の駒部１３の取付孔４１内に配置されたカバー部材４５の中間部が、取付駒１０の開口部１５から外部に露呈し、このカバー部材４５を通して筒状部材２１の中間部が見える。また、ばね棒９の一対のピン部材１９は、ばね棒９のコイルばね２０のばね力によってパイプ部１８から押し出されて、一対の駒部１３の取付孔４１から外部に突出する。さらに、このピン部材１９の操作突起１９ａは、一対の駒部１３の切欠き部１３ａとカバー部材４５の切欠き部４７とに対応して取付駒１０の下側に露呈する。   In this state, an intermediate portion of the cover member 45 disposed in the attachment hole 41 of the pair of piece portions 13 of the attachment piece 10 is exposed to the outside from the opening 15 of the attachment piece 10, and is tubular through the cover member 45. The middle part of the member 21 is visible. The pair of pin members 19 of the spring bar 9 is pushed out of the pipe part 18 by the spring force of the coil spring 20 of the spring bar 9 and protrudes outside from the mounting holes 41 of the pair of piece parts 13. Further, the operation protrusion 19 a of the pin member 19 is exposed to the lower side of the mounting piece 10 corresponding to the notch 13 a of the pair of pieces 13 and the notch 47 of the cover member 45.

そして、時計バンド７を腕時計ケース１のバンド取付部６に取り付ける際には、第５実施形態と同様、まず、ばね棒９の一対のピン部材１９をコイルばね２０のばね力に抗してパイプ部１８内に押し込む。この状態で、時計バンド７の取付駒１０を腕時計ケース１のバンド取付部６における一対の取付突起部８間に下側から配置する。このときには、カバー部材４５の両端部を一対の取付突起部８の各切欠き凹部４６内に下側から挿入させて配置し、一対のピン部材１９を一対の取付突起部８の各係止孔１７に対応させる。   When attaching the watch band 7 to the band attaching portion 6 of the watch case 1, first, as in the fifth embodiment, the pair of pin members 19 of the spring bar 9 are piped against the spring force of the coil spring 20. Push into part 18. In this state, the attachment piece 10 of the watch band 7 is disposed between the pair of attachment projections 8 in the band attachment portion 6 of the watch case 1 from below. At this time, both ends of the cover member 45 are arranged to be inserted from below into the notch recesses 46 of the pair of attachment projections 8, and the pair of pin members 19 are inserted into the respective locking holes of the pair of attachment projections 8. 17 corresponds.

すると、一対のピン部材１９がコイルばね２０のばね力によってパイプ部１８内から押し出され、この押し出された一対のピン部材１９が一対の取付突起部８の各係止孔１７にそれぞれ挿入される。これにより、カバー部材４５の両端部が一対の取付突起部８における各切欠き凹部４６の内面に弾力的に当接した状態で、時計バンド７の取付駒１０が腕時計ケース１のバンド取付部６にばね棒９によって取り付けられることにより、時計バンド７が腕時計ケース１のバンド取付部６に位置規制されて取り付けられる。   Then, the pair of pin members 19 are pushed out from the inside of the pipe portion 18 by the spring force of the coil spring 20, and the pair of pushed pin members 19 are inserted into the respective locking holes 17 of the pair of attachment projections 8. . Thereby, the attachment piece 10 of the watch band 7 is attached to the band attachment portion 6 of the watch case 1 in a state where both end portions of the cover member 45 are elastically in contact with the inner surfaces of the notch recesses 46 in the pair of attachment projections 8. The watch band 7 is attached to the band attaching portion 6 of the watch case 1 by being attached by the spring bar 9.

一方、時計バンド７を腕時計ケース１のバンド取付部６から取り外す場合には、第５実施形態と同様、一対の駒部１３の切欠き部１３ａとカバー部材４５の切欠き部４７とが対応した箇所にドライバーなどの工具（図示せず）を挿入して、ばね棒９の両端に位置する一対のピン部材１９の各操作突起１９ａをコイルばね２０のばね力に抗してパイプ部１８内に向けて移動させる。   On the other hand, when the watch band 7 is removed from the band attaching portion 6 of the watch case 1, the notch portions 13a of the pair of piece portions 13 and the notch portions 47 of the cover member 45 correspond to each other as in the fifth embodiment. A tool such as a screwdriver (not shown) is inserted into the location, and the operation projections 19a of the pair of pin members 19 located at both ends of the spring bar 9 are put into the pipe portion 18 against the spring force of the coil spring 20. Move towards.

すると、一対のピン部材１９が一対の取付突起部８の各係止孔１７から抜け出すので、第５実施形態と同様、時計バンド７の取付駒１０がバンド取付部６の一対の取付突起部８から取り外せる状態になる。これにより、時計バンド７を腕時計ケース１のバンド取付部６から取り外巣ことができる。   Then, since the pair of pin members 19 comes out from the respective locking holes 17 of the pair of attachment projections 8, the attachment piece 10 of the watch band 7 is paired with the pair of attachment projections 8 of the band attachment portion 6 as in the fifth embodiment. It can be removed from. Thereby, the watch band 7 can be removed from the band attaching portion 6 of the watch case 1.

このように、この腕時計のバンド取付構造によれば、第５実施形態と同様の作用効果があるほか、腕時計ケース１のバンド取付部６における一対の取付突起部８に、カバー部材４５の両端部およびカーボン繊維からなる筒状部材２１の両端部が挿入する一対の挿入部である切欠き凹部４６が設けられていることにより、第５実施形態よりも強固に時計バンド７を腕時計ケース１のバンド取付部６に取り付けることができる。   As described above, according to the wristband mounting structure of this wrist watch, there are the same functions and effects as those of the fifth embodiment, and the pair of mounting protrusions 8 in the band mounting portion 6 of the wristwatch case 1 have both ends of the cover member 45. And the cutout recess 46, which is a pair of insertion portions into which both ends of the cylindrical member 21 made of carbon fiber are inserted, makes the watchband 7 stronger than the band of the fifth embodiment. It can be attached to the attachment portion 6.

（第７実施形態）
次に、図２８〜図３３を参照して、この発明を腕時計に適用した第７実施形態について説明する。この場合には、図１５〜図１８に示された第４実施形態と同一部分に同一符号を付して説明する。
この腕時計は、図２８〜図３０に示すように、時計バンド２４の一端部に設けられた一対のバンド端部２６の各取付孔３６に対するカーボン繊維の筒状部材２１の回転を阻止する回転防止板５０を備えた構成であり、これ以外は第４実施形態とほぼ同じ構成になっている。 (Seventh embodiment)
Next, a seventh embodiment in which the present invention is applied to a wristwatch will be described with reference to FIGS. In this case, the same parts as those in the fourth embodiment shown in FIGS.
As shown in FIGS. 28 to 30, this wristwatch prevents rotation of the carbon fiber tubular member 21 with respect to the mounting holes 36 of the pair of band end portions 26 provided at one end portion of the watch band 24. It is the structure provided with the board 50, and it becomes the substantially the same structure as 4th Embodiment except this.

この場合、カーボン繊維からなる筒状部材２１の外周面には、軟質の合成樹脂からなる円筒状のカバー部材３５が設けられている。このカバー部材３５は、第４実施形態と同様、ウレタン樹脂、シリコーン樹脂などのエラストマー樹脂の透明または半透明の軟質の合成樹脂からなり、筒状部材２１の外周面にインサート成形によって一体に形成されている。このカバー部材３５は、筒状部材２１の軸方向の長さよりも長く形成されている。   In this case, a cylindrical cover member 35 made of soft synthetic resin is provided on the outer peripheral surface of the cylindrical member 21 made of carbon fiber. As in the fourth embodiment, the cover member 35 is made of a transparent or translucent soft synthetic resin of an elastomer resin such as urethane resin or silicone resin, and is integrally formed on the outer peripheral surface of the cylindrical member 21 by insert molding. ing. The cover member 35 is formed longer than the length of the cylindrical member 21 in the axial direction.

また、時計バンド２４は、第４実施形態と同様、ウレタン樹脂などの軟質の合成樹脂からなり、腕時計ケース１のバンド取付部６における一対の取付突起部８間に配置される一端部の中間部に開口部２５が底部を除いて設けられ、これにより開口部２５の両側に一対のバンド端部２６が形成された構成になっている。   Similarly to the fourth embodiment, the watch band 24 is made of a soft synthetic resin such as urethane resin, and is an intermediate portion of one end portion disposed between the pair of mounting projections 8 in the band mounting portion 6 of the watch case 1. The opening 25 is provided except for the bottom, and a pair of band end portions 26 are formed on both sides of the opening 25.

この一対のバンド端部２６には、図２８〜図３０に示すように、カバー部材３５が筒状部材２１と共に挿入する取付孔３６が設けられている。また、この一対のバンド端部２６の各外端部には、第４実施形態と同様、ばね棒９のピン部材１９の操作突起１９ａを操作するための切欠き部２９が下側に開放されて設けられている。   The pair of band end portions 26 are provided with mounting holes 36 through which the cover member 35 is inserted together with the tubular member 21 as shown in FIGS. Further, notches 29 for operating the operation projections 19a of the pin member 19 of the spring bar 9 are opened downward at the outer ends of the pair of band ends 26, as in the fourth embodiment. Is provided.

また、筒状部材２１は、図２９に示すように、その軸方向の長さが、ばね棒９のパイプ部１８の長さとほぼ同じ長さに形成されている。すなわち、この筒状部材２１は、その軸方向の長さが、腕時計ケース１のバンド取付部６における一対の取付突起部８間の長さよりも短く、かつ一対のバンド端部２６の各切欠き部２９間の長さとほぼ同じ長さに形成されている。これにより、筒状部材２１は、その両端部が一対のバンド端部２６の各切欠き部２９内に突出しないように形成されている。   Further, as shown in FIG. 29, the cylindrical member 21 has an axial length that is substantially the same as the length of the pipe portion 18 of the spring bar 9. That is, the cylindrical member 21 has an axial length that is shorter than the length between the pair of attachment projections 8 in the band attachment portion 6 of the watch case 1, and the notches in the pair of band end portions 26. The length between the portions 29 is substantially the same. Thereby, the cylindrical member 21 is formed such that both end portions thereof do not protrude into the respective cutout portions 29 of the pair of band end portions 26.

一方、カバー部材３５は、図２９に示すように、その軸方向の長さが、ばね棒９のパイプ部１８の長さよりも長く、かつ腕時計ケース１のバンド取付部６における一対の取付突起部８間の長さと同じか、それよりも少し短く形成されている。このカバー部材３５の両端部には、ピン部材１９の操作突起１９ａを操作するための切欠き部３７がバンド端部２６の切欠き部２９に対応して設けられている。このカバー部材３５は、その各切欠き部３７間の長さが、一対のバンド端部２６の各切欠き部２９間の長さよりも短く、かつ筒状部材２１の長さほぼ同じ長さに形成されている。   On the other hand, as shown in FIG. 29, the cover member 35 has an axial length longer than the length of the pipe portion 18 of the spring bar 9 and a pair of attachment projections in the band attachment portion 6 of the watch case 1. The length is equal to or slightly shorter than the length between the eight. At both ends of the cover member 35, notches 37 for operating the operation protrusions 19 a of the pin member 19 are provided corresponding to the notches 29 of the band end 26. In the cover member 35, the length between the notches 37 is shorter than the length between the notches 29 of the pair of band ends 26, and the length of the cylindrical member 21 is substantially the same. Is formed.

これにより、ばね棒９のピン部材１９の操作突起１９ａは、図２９に示すように、バンド端部２６の切欠き部２９およびカバー部材３５の切欠き部３７を通して、時計バンド２４の下側に露呈するように構成されている。また、このカバー部材３５の外周面には、一対のバンド端部２６に設けられた取付孔３６の内周面に弾力的に圧接する複数の突起部３８が円周方向に所定間隔で設けられている。   As a result, the operation protrusion 19a of the pin member 19 of the spring bar 9 passes through the cutout portion 29 of the band end portion 26 and the cutout portion 37 of the cover member 35 as shown in FIG. It is configured to be exposed. A plurality of protrusions 38 that are elastically pressed against the inner peripheral surfaces of the mounting holes 36 provided in the pair of band end portions 26 are provided on the outer peripheral surface of the cover member 35 at predetermined intervals in the circumferential direction. ing.

ところで、筒状部材２１は、図２９〜図３３に示すように、回転防止板５０によって時計バンド２４の取付孔３６に対する筒状部材２１の回転が阻止されるように構成されている。すなわち、回転防止板５０は、ステンレスなどの金属からなる板ばねであり、筒状部材２１の軸方向に沿って弾性変形する帯板状に形成されている。この回転防止板５０は、カバー部材３５の外周面と時計バンド２４における一対のバンド端部２６の取付孔３６の内周面との間に配置されるように構成されている。   By the way, as shown in FIGS. 29-33, the cylindrical member 21 is comprised so that rotation of the cylindrical member 21 with respect to the attachment hole 36 of the timepiece band 24 may be blocked | prevented by the rotation prevention board 50. FIG. That is, the rotation prevention plate 50 is a leaf spring made of a metal such as stainless steel, and is formed in a belt plate shape that is elastically deformed along the axial direction of the tubular member 21. The rotation preventing plate 50 is configured to be disposed between the outer peripheral surface of the cover member 35 and the inner peripheral surface of the attachment hole 36 of the pair of band end portions 26 in the watch band 24.

また、この回転防止板５０は、図２９〜図３３に示すように、筒状部材２１の軸方向における長さがカバー部材３５の切欠き部３７間の長さと同じ長さに形成され、筒状部材２１の軸方向と直交する径方向の長さがカバー部材３５の円周方向における複数の突起部３８間の長さと同じか、それよりも短い長さに形成されている。また、この回転防止板５０は、その厚みが複数の突起部３８の突出長さ、つまり突起部３８の高さと同じか、それよりも薄く形成されている。   Further, as shown in FIGS. 29 to 33, the rotation preventing plate 50 is formed such that the length of the cylindrical member 21 in the axial direction is the same as the length between the cutout portions 37 of the cover member 35. The length of the radial direction perpendicular to the axial direction of the member 21 is the same as or shorter than the length between the plurality of protrusions 38 in the circumferential direction of the cover member 35. Further, the rotation preventing plate 50 is formed so that its thickness is the same as or less than the protruding length of the plurality of protruding portions 38, that is, the height of the protruding portions 38.

これにより、回転防止板５０は、図３３に示すように、その長手方向つまり筒状部材２１の軸方向に沿う中間部、言い換えれば回転防止板５０の長手方向と直交する方向の中間部が、カバー部材３５の外周面を筒状部材２１の中心軸に向かう径方向に押し付けるように構成されている。また、回転防止板５０は、その両側辺に位置する各端部５０ａが、一対のバンド端部２６に設けられた各取付孔３６の内周面に押し付けられて食い込むように構成されている。   Thereby, as shown in FIG. 33, the rotation prevention plate 50 has an intermediate portion along the longitudinal direction, that is, the axial direction of the cylindrical member 21, in other words, an intermediate portion in a direction orthogonal to the longitudinal direction of the rotation prevention plate 50. The outer peripheral surface of the cover member 35 is configured to be pressed in the radial direction toward the central axis of the tubular member 21. Further, the rotation preventing plate 50 is configured such that the end portions 50 a located on both sides thereof are pressed against the inner peripheral surfaces of the mounting holes 36 provided in the pair of band end portions 26.

さらに、この回転防止板５０は、図２９〜図３３に示すように、カバー部材３５の両端面に当接する一対の位置規制部５１を備えている。すなわち、一対の位置規制部５１は、回転防止板５０の両端部を筒状部材２１の軸中心に向けて折り曲げたものである。これら一対の位置規制部５１は、カバー部材３５の両側に位置する各切欠き部３７の外端面に当接することにより、回転防止板５０がカバー部材３５および筒状部材２１に対してその軸方向に位置ずれしないように構成されている。   Further, as shown in FIGS. 29 to 33, the rotation prevention plate 50 includes a pair of position restricting portions 51 that come into contact with both end faces of the cover member 35. That is, the pair of position restricting portions 51 are formed by bending both end portions of the rotation prevention plate 50 toward the axial center of the cylindrical member 21. The pair of position restricting portions 51 are in contact with the outer end surfaces of the cutout portions 37 located on both sides of the cover member 35, so that the rotation prevention plate 50 is axially disposed with respect to the cover member 35 and the cylindrical member 21. It is configured not to be displaced.

この場合、一対の位置規制部５１は、回転防止板５０がカバー部材３５の外周面に配置されて押し付けられた際に、回転防止板５０の弾力性（ばね性）によってカバー部材３５の両側に位置する各切欠き部３７の外端面に弾力的に当接して、カバー部材３５を弾力的に挟み付けることにより、回転防止板５０をカバー部材３５の外周面に取り付けるように構成されている。   In this case, the pair of position restricting portions 51 are arranged on both sides of the cover member 35 due to the elasticity (spring property) of the rotation prevention plate 50 when the rotation prevention plate 50 is arranged and pressed against the outer peripheral surface of the cover member 35. The rotation preventing plate 50 is configured to be attached to the outer peripheral surface of the cover member 35 by elastically abutting the outer end surface of each of the notched portions 37 and sandwiching the cover member 35 elastically.

次に、このような腕時計のバンド取付構造の作用について説明する。
時計バンド２４を腕時計ケース１に取り付ける場合には、まず、筒状部材２１の外周面にインサート成型されたカバー部材３５の外周面に回転防止板５０を取り付ける。このときには、カバー部材３５の切欠き部３７間に位置し、かつカバー部材３５の複数の突起部３８間に位置する状態で、カバー部材３５の外周面に回転防止板５０を配置する。 Next, the operation of such a wristwatch band mounting structure will be described.
When attaching the watch band 24 to the watch case 1, first, the anti-rotation plate 50 is attached to the outer peripheral surface of the cover member 35 insert-molded on the outer peripheral surface of the cylindrical member 21. At this time, the anti-rotation plate 50 is disposed on the outer peripheral surface of the cover member 35 in a state located between the notches 37 of the cover member 35 and between the plurality of protrusions 38 of the cover member 35.

この状態で、回転防止板５０の両端部に設けられた一対の位置規制部５１をカバー部材３５の両側に位置する各切欠き部３７の外端面に弾力的に当接させる。このときには、回転防止板５０が軸方向に沿って弾力性（ばね性）を有しているので、この回転防止板５０の弾力によって一対の位置規制部５１がカバー部材３５の両側に位置する各切欠き部３７の外端面に弾力的に当接して、カバー部材３５を弾力的に挟み付けることにより、カバー部材３５の外周面に回転防止板５０が取り付けられる。   In this state, the pair of position restricting portions 51 provided at both ends of the rotation preventing plate 50 are elastically brought into contact with the outer end surfaces of the notch portions 37 located on both sides of the cover member 35. At this time, since the rotation preventing plate 50 has elasticity (spring property) along the axial direction, the pair of position restricting portions 51 are positioned on both sides of the cover member 35 by the elasticity of the rotation preventing plate 50. The rotation preventing plate 50 is attached to the outer peripheral surface of the cover member 35 by elastically contacting the outer end surface of the notch 37 and elastically sandwiching the cover member 35.

そして、このように回転防止板５０が取り付けられたカバー部材３５を筒状部材２１と共に時計バンド２４の一端部に設けられた一対のバンド端部２６の各取付孔３６内に挿入する。このときには、カバー部材３５の両側に位置する各切欠き部３７を、時計バンド２４における一対のバンド端部２６の下部に設けられた切欠き部２９に対応させ、この状態でカバー部材３５を回転防止板５０と共に一対のバンド端部２６の各取付孔３６内に挿入する。   Then, the cover member 35 to which the rotation preventing plate 50 is attached in this way is inserted into each attachment hole 36 of the pair of band end portions 26 provided at one end portion of the watch band 24 together with the cylindrical member 21. At this time, the notches 37 located on both sides of the cover member 35 are made to correspond to the notches 29 provided below the pair of band ends 26 of the watch band 24, and the cover member 35 is rotated in this state. It inserts in each attachment hole 36 of a pair of band edge part 26 with the prevention board 50. FIG.

これにより、筒状部材２１は、その両端部が一対のバンド端部２６の各切欠き部２９内に突出すことがなく、一対のバンド端部２６の各取付孔３６内に配置される。また、カバー部材３５は、その両端部が一対のバンド端部２６の両端部に対応し、この状態でカバー部材３５の中間部が時計バンド２４における一対のバンド端部２６の開口部２５から上側に露呈し、この露呈したカバー部材３５を通して筒状部材２１が上側から見える。   As a result, the cylindrical member 21 is disposed in each mounting hole 36 of the pair of band end portions 26 without projecting both ends thereof into the respective notch portions 29 of the pair of band end portions 26. Further, both ends of the cover member 35 correspond to both ends of the pair of band end portions 26, and in this state, an intermediate portion of the cover member 35 is located above the openings 25 of the pair of band end portions 26 in the watch band 24. The cylindrical member 21 can be seen from above through the exposed cover member 35.

また、このときには、カバー部材３５の外周面に設けられた複数の突起部３８が、一対のバンド端部２６に設けられた各取付孔３６の内周面に弾接する。このため、カバー部材３５および筒状部材２１が一対のバンド端部２６の各取付孔３６内にガタツクことがなく、確実にかつ良好に取り付けられる。   At this time, the plurality of protrusions 38 provided on the outer peripheral surface of the cover member 35 are brought into elastic contact with the inner peripheral surfaces of the mounting holes 36 provided in the pair of band end portions 26. For this reason, the cover member 35 and the cylindrical member 21 are reliably and satisfactorily attached without being rattled in the attachment holes 36 of the pair of band end portions 26.

この状態では、回転防止板５０がカバー部材３５の外周面と時計バンド２４における一対のバンド端部２６の取付孔３６の内周面との間に挟み込まれる。このときには、カバー部材３５と時計バンド２４とが弾力性を有する合成樹脂で形成されている。これにより、回転防止板５０の長手方向、つまり筒状部材２１の軸方向に沿う中間部が、図３３に示すように、カバー部材３５の外周面を筒状部材２１の中心軸に向かう径方向に押し付けて弾性変形させる。   In this state, the rotation prevention plate 50 is sandwiched between the outer peripheral surface of the cover member 35 and the inner peripheral surface of the attachment hole 36 of the pair of band end portions 26 in the watch band 24. At this time, the cover member 35 and the watch band 24 are formed of a synthetic resin having elasticity. As a result, the longitudinal direction of the rotation prevention plate 50, that is, the intermediate portion along the axial direction of the cylindrical member 21 has a radial direction in which the outer peripheral surface of the cover member 35 faces the central axis of the cylindrical member 21, as shown in FIG. To be elastically deformed.

また、このときには、回転防止板５０の両側辺に位置する各端部５０ａが、図３３に示すように、一対のバンド端部２６に設けられた各取付孔３６の内周面に押し付けられて食い込む。このため、カバー部材３５は、回転防止板５０によって一対のバンド端部２６の各取付孔３６内で回転することなく配置される。これにより、筒状部材２１も、カバー部材３５と共に一対のバンド端部２６の各取付孔３６内で回転することなく配置される。   At this time, the end portions 50a located on both sides of the rotation preventing plate 50 are pressed against the inner peripheral surfaces of the mounting holes 36 provided in the pair of band end portions 26 as shown in FIG. Bite. For this reason, the cover member 35 is arrange | positioned without rotating in each attachment hole 36 of a pair of band edge part 26 by the rotation prevention board 50. FIG. Thereby, the cylindrical member 21 is also arrange | positioned without rotating in each attachment hole 36 of a pair of band edge part 26 with the cover member 35. FIG.

この状態で、筒状部材２１内にばね棒９を挿入する。このときには、ばね棒９の一対のピン部材１９が、ばね棒９のコイルばね２０のばね力によってパイプ部１８から押し出されて、一対のバンド端部２６に設けられた各取付孔３６から外部に突出する。また、このピン部材１９の操作突起１９ａは、一対のバンド端部２６の切欠き部２９およびカバー部材３５の切欠き部３７に対応して、時計バンド２４の一端部の下側に露呈する。   In this state, the spring bar 9 is inserted into the cylindrical member 21. At this time, the pair of pin members 19 of the spring bar 9 are pushed out of the pipe portion 18 by the spring force of the coil spring 20 of the spring bar 9 and are externally exposed from the mounting holes 36 provided in the pair of band end portions 26. Protruding. Further, the operation protrusion 19 a of the pin member 19 is exposed to the lower side of one end portion of the watch band 24 corresponding to the notch portion 29 of the pair of band end portions 26 and the notch portion 37 of the cover member 35.

そして、時計バンド２４を腕時計ケース１のバンド取付部６に取り付ける際には、まず、ばね棒９の一対のピン部材１９をコイルばね２０のばね力に抗してパイプ部１８内に押し込む。この状態で、時計バンド２４の一対のバンド端部２６を腕時計ケース１のバンド取付部６における一対の取付突起部８間に配置し、ばね棒９の一対のピン部材１９を一対の取付突起部８の各係止孔１７に対応させる。   When the watch band 24 is attached to the band attaching portion 6 of the watch case 1, first, the pair of pin members 19 of the spring bar 9 are pushed into the pipe portion 18 against the spring force of the coil spring 20. In this state, the pair of band end portions 26 of the watch band 24 are disposed between the pair of mounting projections 8 in the band mounting portion 6 of the watch case 1, and the pair of pin members 19 of the spring bar 9 are paired with the pair of mounting projections. 8 corresponding to the respective locking holes 17.

すると、一対のピン部材１９がコイルばね２０のばね力によってパイプ部１８内から押し出され、この押し出された一対のピン部材１９が一対の取付突起部８の各係止孔１７にそれぞれ挿入される。これにより、時計バンド２４の一対のバンド端部２６が腕時計ケース１のバンド取付部６の一対の取付突起部８にばね棒９によって取り付けられ、時計バンド２４が腕時計ケース１のバンド取付部６に取り付けられる。   Then, the pair of pin members 19 are pushed out from the inside of the pipe portion 18 by the spring force of the coil spring 20, and the pair of pushed pin members 19 are inserted into the respective locking holes 17 of the pair of attachment projections 8. . As a result, the pair of band end portions 26 of the watch band 24 are attached to the pair of attachment projections 8 of the band attachment portion 6 of the watch case 1 by the spring bar 9, and the watch band 24 is attached to the band attachment portion 6 of the watch case 1. It is attached.

一方、時計バンド２４を腕時計ケース１のバンド取付部６から取り外す場合には、一対のバンド端部２６の切欠き部２９およびカバー部材３５の切欠き部３７が対応した箇所に、ドライバーなどの工具（図示せず）を挿入して、ばね棒９の両端に位置する一対のピン部材１９の各操作突起１９ａをコイルばね２０のばね力に抗してパイプ部１８内に向けて移動させる。   On the other hand, when the watch band 24 is removed from the band attaching portion 6 of the watch case 1, a tool such as a screwdriver is provided at a position corresponding to the notch portion 29 of the pair of band end portions 26 and the notch portion 37 of the cover member 35. (Not shown) is inserted, and the operation projections 19a of the pair of pin members 19 positioned at both ends of the spring bar 9 are moved toward the pipe portion 18 against the spring force of the coil spring 20.

すると、一対のピン部材１９が一対の取付突起部８の各係止孔１７から抜け出すので、時計バンド２４の一対のバンド端部２６がバンド取付部６の一対の取付突起部８から取り外せる状態になる。これにより、時計バンド２４を腕時計ケース１のバンド取付部６から取り外すことができる。   Then, the pair of pin members 19 come out from the respective locking holes 17 of the pair of attachment projections 8, so that the pair of band end portions 26 of the watch band 24 can be detached from the pair of attachment projections 8 of the band attachment portion 6. Become. Thereby, the watch band 24 can be detached from the band attaching portion 6 of the watch case 1.

このように、この腕時計のバンド取付構造によれば、一端部に取付孔３６が設けられた時計バンド２４と、この時計バンド２４の一端部が配置され、かつ取付孔３６に対応する一対の係止孔１７を有する腕時計ケース１のバンド取付部６と、時計バンド２４の取付孔３６に挿入され、かつ両端部がバンド取付部６の一対の係止孔１７に係合するばね棒９と、カーボン繊維によって形成され、かつばね棒９の外周に装着された筒状部材２１と、時計バンド２４の取付孔３６に対する筒状部材２１の回転を阻止する回転防止板５０と、を備えているので、バンド取付部６に対する時計バンド２４の取付強度を大幅に向上させることができ、かつ筒状部材２１を一定の状態で位置規制することができる。   As described above, according to the wristband mounting structure of the wristwatch, the watch band 24 having the mounting hole 36 provided at one end thereof, and the pair of engagements corresponding to the mounting hole 36 in which one end of the watch band 24 is disposed. A band attachment portion 6 of the watch case 1 having a stop hole 17; a spring rod 9 inserted into the attachment hole 36 of the watch band 24 and having both ends engaged with the pair of locking holes 17 of the band attachment portion 6; Since it includes a cylindrical member 21 formed of carbon fiber and mounted on the outer periphery of the spring bar 9, and a rotation preventing plate 50 that prevents the cylindrical member 21 from rotating relative to the mounting hole 36 of the watch band 24. The strength of attaching the watch band 24 to the band attaching portion 6 can be greatly improved, and the position of the cylindrical member 21 can be regulated in a certain state.

すなわち、このバンド取付構造では、カーボン繊維によって形成された筒状部材２１の内部にばね棒９のパイプ部１８が挿入されていることにより、筒状部材２１によってばね棒９の曲げ強度を十分に補強して高めることができるので、筒状部材２１およびばね棒９によって腕時計ケース１のバンド取付部６に対する時計バンド２４の取付強度を大幅に向上させることができると共に、時計バンド２４の取付孔３６に対する筒状部材２１の回転を回転防止板５０によって防ぐことができるので、筒状部材２１を一定の状態で安定させて位置規制することができる。   That is, in this band mounting structure, the pipe member 18 of the spring bar 9 is inserted into the cylindrical member 21 formed of carbon fiber, so that the bending strength of the spring bar 9 is sufficiently increased by the cylindrical member 21. Since it can be reinforced and enhanced, the attachment strength of the watch band 24 to the band attaching portion 6 of the watch case 1 can be greatly improved by the tubular member 21 and the spring bar 9, and the attachment hole 36 of the watch band 24 can be improved. Since the rotation of the cylindrical member 21 can be prevented by the rotation prevention plate 50, the cylindrical member 21 can be stabilized and regulated in a fixed state.

この場合、筒状部材２１は、カーボン繊維によって形成されていることにより、第１実施形態と同様、強度が極めて高く、ばね棒９を十分に補強してばね棒９の曲げ強度を確実に高めることができるほか、重さが軽いため、筒状部材２１の外径が大きくても、ばね棒９および筒状部材２１全体の重量の増加を大幅に抑えることができる。   In this case, since the cylindrical member 21 is formed of carbon fiber, the strength is extremely high as in the first embodiment, and the spring bar 9 is sufficiently reinforced to reliably increase the bending strength of the spring bar 9. In addition, since the weight is light, even if the outer diameter of the tubular member 21 is large, an increase in the weight of the spring bar 9 and the entire tubular member 21 can be significantly suppressed.

また、時計バンド２４の一端部には、筒状部材２１を露呈させるための開口部２５が設けられていることにより、第１実施形態と同様、この開口部２５を通して筒状部材２１を外部から見ることができるので、ばね棒９よりも太い筒状部材２１によって強度的な安心感を与えることができ、これにより商品質感を向上させることができると共に、デザイン的にも好ましいものを提供することができる。   In addition, since an opening 25 for exposing the tubular member 21 is provided at one end of the watch band 24, the tubular member 21 is externally passed through the opening 25 as in the first embodiment. Since it can be seen, the cylindrical member 21 thicker than the spring bar 9 can give a strong sense of security, thereby improving the product texture and providing a favorable design. Can do.

また、筒状部材２１の外周面には、透明または半透明の軟質合成樹脂からなるカバー部材３５が設けられているので、第４実施形態と同様、カバー部材３５によって筒状部材２１を保護することができると共に、カバー部材３５が外部から衝撃を受けた際に、その衝撃が筒状部材２１に伝わないように緩衝することができ、これにより筒状部材２１の傷付きによるカーボン繊維の散乱を確実にかつ良好に防ぐことができる。   Moreover, since the cover member 35 which consists of transparent or semi-transparent soft synthetic resin is provided in the outer peripheral surface of the cylindrical member 21, the cylindrical member 21 is protected by the cover member 35 similarly to 4th Embodiment. In addition, when the cover member 35 receives an impact from the outside, the cover member 35 can be buffered so that the impact is not transmitted to the cylindrical member 21, thereby scattering the carbon fiber due to the scratch of the cylindrical member 21. Can be reliably and well prevented.

この場合、カバー部材３５の外周面には、時計バンド２４の取付孔３６の内周面に接触する複数の突起部３８が設けられ、時計バンド２４は、ウレタンなどの弾力を有する合成樹脂で形成されているので、カバー部材３５を時計バンド２４の取付孔３６内で軸方向および径方向にガタツクことがなく位置規制することができ、これにより筒状部材２１を時計バンド２４の取付孔３６内に確実にかつ良好に取り付けることができる。   In this case, the outer peripheral surface of the cover member 35 is provided with a plurality of protrusions 38 that come into contact with the inner peripheral surface of the mounting hole 36 of the watch band 24, and the watch band 24 is formed of a synthetic resin having elasticity such as urethane. Therefore, the position of the cover member 35 can be regulated in the mounting hole 36 of the watch band 24 without rattling in the axial direction and the radial direction. Can be securely and satisfactorily attached.

また、回転防止板５０は、カバー部材３５の外周面と時計バンド２４の取付孔３６の内周面との間に配置されているので、回転防止板５０の長手方向に沿う中間部、つまり回転防止板５０の長手方向と直交する方向の中間部がカバー部材３５を筒状部材２１に押し付けて弾性変形させることができると共に、回転防止板５０の長手方向に沿う両側辺に位置する各端部５０ａを、一対のバンド端部２６に設けられた各取付孔３６の内周面に押し付けて食い込ませることができる。   Further, since the rotation preventing plate 50 is disposed between the outer peripheral surface of the cover member 35 and the inner peripheral surface of the mounting hole 36 of the watch band 24, the intermediate portion along the longitudinal direction of the rotation preventing plate 50, that is, rotation. The intermediate portion in the direction orthogonal to the longitudinal direction of the prevention plate 50 can press the cover member 35 against the cylindrical member 21 to be elastically deformed, and each end located on both sides along the longitudinal direction of the rotation prevention plate 50 50a can be pressed against the inner peripheral surface of each mounting hole 36 provided in the pair of band end portions 26 and bite.

このため、回転防止板５０によって筒状部材２１およびカバー部材３５が時計バンド２４の取付孔３６内で回転するのを確実にかつ良好に防ぐことができ、これにより筒状部材２１およびカバー部材３５を時計バンド２４の取付孔２７内に確実にかつ良好に取り付けることができる。   For this reason, the rotation preventing plate 50 can reliably and well prevent the cylindrical member 21 and the cover member 35 from rotating in the mounting hole 36 of the watch band 24, and thereby the cylindrical member 21 and the cover member 35. Can be securely and satisfactorily mounted in the mounting hole 27 of the watch band 24.

また、この回転防止板５０は、カバー部材３５の両端面に当接する一対の位置規制部５１を備えていることにより、カバー部材３５に対して回転防止板５０がカバー部材３５および筒状部材２１の軸方向に位置ずれすることがなく、回転防止板５０をカバー部材３５の外周面に確実にかつ良好に配置することができる。   Further, the rotation prevention plate 50 includes a pair of position restricting portions 51 that come into contact with both end faces of the cover member 35, so that the rotation prevention plate 50 is covered with the cover member 35 and the cylindrical member 21. The rotation prevention plate 50 can be reliably and satisfactorily disposed on the outer peripheral surface of the cover member 35 without being displaced in the axial direction.

すなわち、一対の位置規制部５１は、回転防止板５０の両端部を筒状部材２１の軸中心に向けて折り曲げたものであり、カバー部材３５の両側に位置する各切欠き部３７の外端面に当接して、カバー部材３５を弾力的に挟み付けることにより、回転防止板５０が筒状部材２１の軸方向に位置ずれすることがなく、回転防止板５０をカバー部材３５の外周面に確実にかつ良好に取り付けることができる。   That is, the pair of position restricting portions 51 are formed by bending both end portions of the rotation preventing plate 50 toward the axial center of the cylindrical member 21, and the outer end surfaces of the notch portions 37 located on both sides of the cover member 35. The anti-rotation plate 50 is not displaced in the axial direction of the tubular member 21 and the anti-rotation plate 50 is securely attached to the outer peripheral surface of the cover member 35 by elastically sandwiching the cover member 35. And can be mounted well.

この場合、回転防止板５０は、カバー部材３５の軸方向（長手方向）に沿ってばね性（弾力性）を有していることにより、回転防止板５０をカバー部材３５の外周面に取り付ける際に、回転防止板５０をカバー部材３５の径方向に弾力的に変形させて、一対の位置規制部５１をカバー部材３５の両側に位置する各切欠き部３７の外端面に弾力的に当接させて挟み付けることができ、これにより回転防止板５０をカバー部材３５の外周面に確実にかつ良好に取り付けることができるので、組み付け作業性の向上を図ることができる。   In this case, the anti-rotation plate 50 has springiness (elasticity) along the axial direction (longitudinal direction) of the cover member 35, so that the anti-rotation plate 50 is attached to the outer peripheral surface of the cover member 35. Further, the rotation preventing plate 50 is elastically deformed in the radial direction of the cover member 35, and the pair of position restricting portions 51 are elastically brought into contact with the outer end surfaces of the notch portions 37 located on both sides of the cover member 35. As a result, the rotation prevention plate 50 can be reliably and satisfactorily attached to the outer peripheral surface of the cover member 35, so that the assembly workability can be improved.

また、この回転防止板５０は、カバー部材３５の複数の突起部３８間に位置した状態で、カバー部材３５の外周面に配置されていることにより、回転防止板５０を複数の突起部３８によってカバー部材３５の円周方向に沿って位置ずれしないように確実に位置規制することができ、これによっても回転防止板５０をカバー部材３５の外周面に確実にかつ良好に配置することができる。   The rotation prevention plate 50 is disposed on the outer peripheral surface of the cover member 35 in a state where the rotation prevention plate 50 is located between the plurality of projections 38 of the cover member 35. The position of the cover member 35 can be reliably regulated so as not to be displaced along the circumferential direction of the cover member 35, and the rotation prevention plate 50 can be reliably and satisfactorily disposed on the outer peripheral surface of the cover member 35.

なお、上述した第７実施形態では、回転防止板５０を単純な帯板状に形成した場合について述べたが、これに限らず、例えば図３４および図３５に示す第１変形例のように、回転防止板５０に複数の孔５２を設けた構成であっても良い。この場合、複数の孔５２は、回転防止板５０の長手方向に長い長方形の孔であり、回転防止板５０の長手方向に沿ってそれぞれ設けられている。   In the above-described seventh embodiment, the case where the rotation prevention plate 50 is formed in a simple band plate shape is described. However, the present invention is not limited to this, for example, as in the first modification shown in FIGS. 34 and 35. The rotation prevention plate 50 may be provided with a plurality of holes 52. In this case, the plurality of holes 52 are rectangular holes that are long in the longitudinal direction of the rotation prevention plate 50, and are provided along the longitudinal direction of the rotation prevention plate 50.

このような回転防止板５０によれば、筒状部材２１の外周面に設けられたカバー部材３５の外周面と時計バンド２４の取付孔３６の内周面との間に配置された際に、第７実施形態と同様、回転防止板５０の長手方向に沿う中間部がカバー部材３５を筒状部材２１に押し付けて弾性変形させることができると共に、回転防止板５０の長手方向に沿う両側辺に位置する各端部５０ａを、一対のバンド端部２６に設けられた各取付孔３６の内周面に押し付けて食い込ませることができる。   According to such an anti-rotation plate 50, when disposed between the outer peripheral surface of the cover member 35 provided on the outer peripheral surface of the cylindrical member 21 and the inner peripheral surface of the mounting hole 36 of the watch band 24, Similarly to the seventh embodiment, the intermediate portion along the longitudinal direction of the rotation prevention plate 50 can press the cover member 35 against the tubular member 21 to be elastically deformed, and on both sides along the longitudinal direction of the rotation prevention plate 50. Each of the end portions 50 a positioned can be pressed against the inner peripheral surface of each of the attachment holes 36 provided in the pair of band end portions 26 and bite.

この場合、回転防止板５０の長手方向に沿う中間部がカバー部材３５を筒状部材２１に押し付けて弾性変形させた際には、図３５に示すように、回転防止板５０に設けられた複数の孔５２内にカバー部材３５の一部を食い込ませることができる。このため、回転防止板５０によって筒状部材２１およびカバー部材３５が時計バンド２４の取付孔３６内で回転するのを、第７実施形態よりも、確実にかつ良好に防ぐことができる。   In this case, when the intermediate portion along the longitudinal direction of the rotation prevention plate 50 presses the cover member 35 against the cylindrical member 21 and elastically deforms it, as shown in FIG. 35, a plurality of portions provided on the rotation prevention plate 50 are provided. A part of the cover member 35 can be bitten into the hole 52. Therefore, the rotation preventing plate 50 can prevent the cylindrical member 21 and the cover member 35 from rotating in the attachment hole 36 of the watch band 24 more reliably and better than the seventh embodiment.

また、上述した第７実施形態およびその第１変形例では、回転防止板５０をステンレスなどの金属で形成した場合について述べたが、必ずしも金属である必要はなく、例えば硬質の合成樹脂で形成した構成であっても良い。   In the above-described seventh embodiment and the first modification thereof, the case where the rotation prevention plate 50 is formed of a metal such as stainless steel has been described. However, the rotation prevention plate 50 is not necessarily made of metal, and is formed of, for example, a hard synthetic resin. It may be a configuration.

また、上述した第７実施形態およびその第１変形例では、筒状部材２１の外周面にカバー部材３５を設け、このカバー部材３５の外周面と時計バンド２４の一端部に設けられた取付孔３６の内周面との間に回転防止板５０を設けた場合について述べたが、必ずしも筒状部材２１の外周面にカバー部材３５を設ける必要はなく、筒状部材２１の外周面と時計バンド２４の一端部に設けられた取付孔３６の内周面との間に回転防止板５０を設けた構成であっても良い。   Further, in the above-described seventh embodiment and the first modification thereof, the cover member 35 is provided on the outer peripheral surface of the cylindrical member 21, and the mounting holes provided in the outer peripheral surface of the cover member 35 and one end portion of the watch band 24. Although the case where the anti-rotation plate 50 is provided between the inner peripheral surface 36 and the inner peripheral surface 36 is described, it is not always necessary to provide the cover member 35 on the outer peripheral surface of the cylindrical member 21. The structure which provided the rotation prevention board 50 between the inner peripheral surfaces of the attachment hole 36 provided in the one end part of 24 may be sufficient.

さらに、上述した第７実施形態およびその第１変形例では、時計バンド２４が合成樹脂で形成されている場合について述べたが、必ずしも合成樹脂で形成する必要はなく、例えば第１実施形態で述べたように、時計バンド７が金属で形成されていても良い。   Further, in the above-described seventh embodiment and the first modification thereof, the case where the watch band 24 is formed of a synthetic resin has been described. However, it is not always necessary to form the watch band 24 from a synthetic resin. As described above, the watch band 7 may be made of metal.

（第８実施形態）
次に、図３６〜図３８を参照して、この発明を腕時計に適用した第８実施形態について説明する。なお、図２８〜図３３に示された第７実施形態と同一部分には同一符号を付して説明する。

Next, with reference to FIGS. 36 to 38, an eighth embodiment in which the present invention is applied to a wristwatch will be described. In addition, the same code | symbol is attached | subjected and demonstrated to the same part as 7th Embodiment shown by FIGS. 28-33.
As shown in FIGS. 36 to 38, this wristwatch has a configuration different from that of the seventh embodiment in a rotation preventing portion 55 that prevents the cylindrical member 21 from rotating with respect to the mounting hole 36 provided at one end of the watch band 24. Except this, the configuration is almost the same as in the seventh embodiment.

すなわち、この回転防止部５５は、図３６〜図３８に示すように、カバー部材３５の外周面に設けられた位置規制凸部５６と、時計バンド２４の一端部に設けられた一対のバンド端部２６の各取付孔３６の内周面に設けられてカバー部材３５の位置規制凸部５６が係合する位置規制凹部５７と、を備えている。この場合にも、カバー部材３５は、筒状部材２１の外周面にインサート成型によって一体に形成されている。   That is, as shown in FIGS. 36 to 38, the rotation preventing portion 55 includes a position regulating convex portion 56 provided on the outer peripheral surface of the cover member 35 and a pair of band ends provided on one end portion of the watch band 24. Position restriction recesses 57 provided on the inner peripheral surface of each mounting hole 36 of the portion 26 and engaged with the position restriction projections 56 of the cover member 35. Also in this case, the cover member 35 is integrally formed on the outer peripheral surface of the cylindrical member 21 by insert molding.

On the outer peripheral surface of the cover member 35 located at the intermediate portion in the circumferential direction, the cover member 35 is provided continuously between the notches 37 along the axial direction of the tubular member 21.

また、時計バンド２４側の位置規制凹部５７は、図３６および図３７（ｂ）に示すように、断面四角形状の溝部であり、時計バンド２４の一端部に設けられた一対のバンド端部２６の各内端部に設けられた各切欠き部２９の円周方向の中間部に位置する取付孔３６の内周面に、その取付孔３６の軸方向に沿って、取付孔３６の両端に位置する各切欠き部２９間に連続して設けられている。   Further, as shown in FIG. 36 and FIG. 37 (b), the position restricting recess 57 on the watch band 24 side is a groove having a square cross section, and a pair of band end portions 26 provided at one end of the watch band 24. At the both ends of the mounting hole 36 along the axial direction of the mounting hole 36 on the inner peripheral surface of the mounting hole 36 located at the intermediate portion in the circumferential direction of each notch 29 provided at each inner end of the mounting hole 36 It is provided continuously between the notch portions 29 located.

これにより、回転防止部５５は、図３６〜図３８に示すように、筒状部材２１をその外周面に設けられたカバー部材３５と共に時計バンド２４の一端部に設けられた一対のバンド端部２６の各取付孔３６内に挿入する際に、カバー部材３５の位置規制凸部５６が時計バンド２４の取付孔３６の位置規制凹部５７に対応して挿入するように構成されている。   Thereby, as shown in FIGS. 36 to 38, the rotation preventing unit 55 includes a pair of band ends provided at one end of the watch band 24 together with the cover member 35 provided on the outer peripheral surface of the cylindrical member 21. 26, the position restricting convex portion 56 of the cover member 35 is configured to be inserted in correspondence with the position restricting concave portion 57 of the attaching hole 36 of the watch band 24.

また、この回転防止部５５は、図３６〜図３８に示すように、カバー部材３５の位置規制凸部５６が時計バンド２４の取付孔３６の位置規制凹部５７に挿入することにより、カバー部材３５の位置規制凸部５６が時計バンド２４側の位置規制凹部５７に係合し、時計バンド２４の一端部に設けられた取付孔３６に対するカバー部材３５の回転を阻止して、時計バンド２４の取付孔３６に対する筒状部材２１の回転を阻止するように構成されている。   Further, as shown in FIGS. 36 to 38, the rotation preventing portion 55 is configured such that the position restricting convex portion 56 of the cover member 35 is inserted into the position restricting concave portion 57 of the mounting hole 36 of the watch band 24. The position restricting convex portion 56 engages with the position restricting concave portion 57 on the watch band 24 side to prevent the rotation of the cover member 35 with respect to the attachment hole 36 provided at one end of the watch band 24, thereby attaching the watch band 24. The cylindrical member 21 is configured to be prevented from rotating with respect to the hole 36.

このような腕時計のバンド取付構造においても、第７実施形態と同様、カーボン繊維によって形成された筒状部材２１の内部にばね棒９のパイプ部１８が挿入されていることにより、筒状部材２１によってばね棒９の曲げ強度を十分に補強して高めることができるので、筒状部材２１およびばね棒９によって腕時計ケース１のバンド取付部６に対する時計バンド２４の取付強度を大幅に向上させることができると共に、時計バンド２４の取付孔３６に対する筒状部材２１の回転を回転防止部５５によって防ぐことができるので、筒状部材２１を一定の状態で安定させて位置規制することができる。   Even in such a wristband mounting structure, the tubular member 21 is formed by inserting the pipe portion 18 of the spring bar 9 into the tubular member 21 formed of carbon fiber, as in the seventh embodiment. Thus, the bending strength of the spring bar 9 can be sufficiently reinforced and increased, so that the mounting strength of the watch band 24 with respect to the band mounting portion 6 of the watch case 1 can be significantly improved by the tubular member 21 and the spring bar 9. In addition, the rotation of the cylindrical member 21 with respect to the attachment hole 36 of the watch band 24 can be prevented by the rotation preventing portion 55, so that the position of the cylindrical member 21 can be stabilized and regulated in a constant state.

この場合、回転防止部５５は、カバー部材３５の外周面に設けられた位置規制凸部５６と、時計バンド２４の一端部に設けられた一対のバンド端部２６の各取付孔３６の内周面に設けられてカバー部材３５の位置規制凸部５６が係合する位置規制凹部５７と、を備えているので、カバー部材３５の位置規制凸部５６を時計バンド２４側の位置規制凹部５７に係合させることにより、時計バンド２４の一端部に設けられた取付孔３６に対するカバー部材３５の回転を阻止することができるので、時計バンド２４の取付孔３６に対する筒状部材２１の回転を確実に阻止することができる。   In this case, the rotation preventing portion 55 includes an inner circumference of each mounting hole 36 of the position regulating convex portion 56 provided on the outer peripheral surface of the cover member 35 and the pair of band end portions 26 provided on one end portion of the watch band 24. And a position restricting concave portion 57 that is provided on the surface and engages with the position restricting convex portion 56 of the cover member 35. By engaging, the rotation of the cover member 35 with respect to the attachment hole 36 provided at one end of the watch band 24 can be prevented, so that the rotation of the cylindrical member 21 with respect to the attachment hole 36 of the watch band 24 is ensured. Can be blocked.

すなわち、この回転防止部５５は、筒状部材２１をその外周面に設けられたカバー部材３５と共に時計バンド２４の一端部に設けられた一対のバンド端部２６の各取付孔３６内に挿入する際に、カバー部材３５の位置規制凸部５６を時計バンド２４の取付孔３６の位置規制凹部５７に対応させて挿入することにより、カバー部材３５の位置規制凸部５６を時計バンド２４側の位置規制凹部５７に確実にかつ容易に係合させることができ、これにより時計バンド２４の一端部に設けられた取付孔３６に対する筒状部材２１の回転を確実に阻止することができる。   That is, the rotation preventing portion 55 inserts the cylindrical member 21 into the mounting holes 36 of the pair of band end portions 26 provided at one end portion of the watch band 24 together with the cover member 35 provided on the outer peripheral surface thereof. At this time, the position restricting convex portion 56 of the cover member 35 is inserted into the position restricting concave portion 57 of the mounting hole 36 of the watch band 24 by inserting the position restricting convex portion 56 of the cover member 35 into the position on the watch band 24 side. It is possible to reliably and easily engage the restricting concave portion 57, thereby reliably preventing the cylindrical member 21 from rotating with respect to the attachment hole 36 provided at one end of the watch band 24.

なお、上述した第８実施形態では、回転防止部５５の位置規制凸部５６と位置規制凹部５７とを、単純な断面四角形状に形成した場合について述べたが、これに限らず、例えば図３９に示す第２変形例のように構成しても良い。すなわち、この回転防止部５８の位置規制凸部５６と位置規制凹部５７とは、断面四角形状の両側面をアンダーカット形状の傾斜面５６ａ、５７ａに形成した構成になっている。   In the above-described eighth embodiment, the case where the position restricting convex portion 56 and the position restricting concave portion 57 of the rotation preventing portion 55 are formed in a simple quadrangular cross section has been described. You may comprise like the 2nd modification shown in this. That is, the position restricting convex portion 56 and the position restricting concave portion 57 of the rotation preventing portion 58 are configured such that both side surfaces having a quadrangular cross section are formed as inclined surfaces 56a and 57a having an undercut shape.

このように形成された回転防止部５８によれば、カバー部材３５の位置規制凸部５６が時計バンド２４側の位置規制凹部５７に係合すると、位置規制凸部５６が位置規制凹部５７から径方向に抜け出すことがないので、時計バンド２４の一端部に設けられた取付孔３６に対する筒状部材２１の回転を、第８実施形態の回転防止部５５よりも、確実に阻止することができる。   According to the rotation preventing portion 58 formed in this way, when the position restricting convex portion 56 of the cover member 35 engages with the position restricting concave portion 57 on the timepiece band 24 side, the position restricting convex portion 56 has a diameter from the position restricting concave portion 57. Since it does not come out in the direction, the rotation of the cylindrical member 21 with respect to the mounting hole 36 provided at one end of the watch band 24 can be more reliably prevented than the rotation preventing portion 55 of the eighth embodiment.
