It is comprised so that it may be arrange | positioned on the upper surface. As a result, when the end portion 10a of the watch band 10 is attached to each arm portion 17 by the spring bar 20, the connecting portion 18 holds the end portion 10a of the watch band 10 with the spring bar 20 therebetween. It is configured.

ところで、このようなバンド取付構造は、図３および図５に示すように、連結部材１１を中心に緩衝部材１６が回転する際に、緩衝部材１６の回転を制動する制動部２５を備えている。この制動部２５は、各アーム部１７の各薄肉部１７ａと各厚肉部１７ｂとの境界部に設けられた各第１傾斜部２５ａと、これら各第１傾斜部２５ａが対面する一対の取付突起部９における各本体突起部９ａの個所に設けられて各第１傾斜部２５ａが接離可能に圧接摺動するオーバーハング形状の各第２傾斜部２５ｂとを備えている。 By the way, as shown in FIGS. 3 and 5, such a band mounting structure includes a braking portion 25 that brakes the rotation of the buffer member 16 when the buffer member 16 rotates around the connecting member 11. . The braking portion 25 includes a first inclined portion 25a provided at a boundary between each thin portion 17a and each thick portion 17b of each arm portion 17, and a pair of attachments facing each first inclined portion 25a. Each overhang-shaped second inclined portion 25b is provided at a position of each main body protruding portion 9a of the protruding portion 9 and in which each first inclined portion 25a is slidably pressed and slidable.

これにより、制動部２５は、図３および図５に示すように、時計バンド１０が連結部材１１を中心に押し広げられる方向に回転する際に、各アーム部１７の各第１傾斜部２５ａが一対の取付突起部９の各第２傾斜部２５ｂに沿って徐々に押し付けられながら圧接摺動することにより、緩衝部材１６の回転を徐々に重くするように制動すると共に、時計バンド１０の回転をも制動するように構成されている。 As a result, as shown in FIGS. 3 and 5, when the watch band 10 rotates in the direction in which the timepiece band 10 is pushed and spread around the connecting member 11, the first inclined portion 25 a of each arm portion 17 is By pressing and sliding along the second inclined portions 25b of the pair of mounting projections 9 while being pressed gradually, the buffer member 16 is braked to gradually increase its rotation, and the watch band 10 is rotated. Is also configured to brake.

また、このバンド取付構造は、図３および図６に示すように、連結部材１１を中心に緩衝部材１６が回転する際に、その回転範囲を規制する回転規制部２３を備えている。この回転規制部２３は、緩衝部材１６の各アーム部１７の先端部、つまり各アーム部１７の薄肉部１７ａの外周部に設けられた上下一対の規制突起部２３ａ、２３ｂと、これら上下一対の規制突起部２３ａ、２３ｂが回転移動する移動軌跡上に位置する個所のケース本体２に設けられた当接突起部２３ｃと、を備えている。 Further, as shown in FIGS. 3 and 6, the band mounting structure includes a rotation restricting portion 23 that restricts the rotation range when the buffer member 16 rotates around the connecting member 11. The rotation restricting portion 23 includes a pair of upper and lower restricting protrusions 23a and 23b provided at the distal end portion of each arm portion 17 of the buffer member 16, that is, the outer peripheral portion of the thin portion 17a of each arm portion 17, and the pair of upper and lower portions. And a contact protrusion 23c provided on the case body 2 at a position on the movement locus on which the restricting protrusions 23a and 23b rotate.

これにより、回転規制部２３は、図６に示すように、連結部材１１を中心に緩衝部材１６が時計バンド１０の端部１０ａと共に押し上げられる方向（図６において反時計回り方向）に回転した際に、各アーム部１７の薄肉部１７ａにおける上側に位置する規制突起部２３ａがケース本体２の当接突起部２３ｃに上側から当接することにより、緩衝部材１６の押し上げ方向への回転を規制して、時計バンド１０の回転を規制するように構成されている。 Thereby, as shown in FIG. 6, when the rotation restricting portion 23 rotates in the direction in which the buffer member 16 is pushed up together with the end portion 10 a of the watch band 10 (counterclockwise in FIG. 6) around the connecting member 11. In addition, when the restricting projection 23a located on the upper side of the thin portion 17a of each arm portion 17 abuts against the abutment projection 23c of the case body 2 from the upper side, the rotation of the buffer member 16 in the push-up direction is restricted. The rotation of the watch band 10 is restricted.

また、この回転規制部２３は、図６に示すように、連結部材１１を中心に緩衝部材１６が時計バンド１０の端部１０ａと共に押し下げられる方向（図６において時計回り方向）に回転した際に、各アーム部１７の薄肉部１７ａにおける下側に位置する規制突起部２３ｂがケース本体２の当接突起部２３ｃに下側から当接することにより、緩衝部材１６の押し下げ方向への回転を規制して、時計バンド１０の回転を規制するように構成されている。 Further, as shown in FIG. 6, the rotation restricting portion 23 is formed when the buffer member 16 rotates in the direction in which the buffer member 16 is pushed down together with the end portion 10 a of the timepiece band 10 (clockwise direction in FIG. 6). The lower-side regulating projection 23b of the thin-walled portion 17a of each arm 17 abuts against the abutment projection 23c of the case body 2 from below, thereby restricting the rotation of the buffer member 16 in the push-down direction. Thus, the rotation of the watch band 10 is restricted.

At this time, the pipe portion 20a of the spring bar 20 is inserted into the connecting hole 22 of the end portion 10a of the watch band 10, and the pair of pin portions 20b is resisted against the spring force of a coil spring (not shown). In this state, the connecting portion 18 of the buffer member 16 is disposed on the upper surface of the watch band 10, and the arm portions 17 of the buffer member 16 are made to correspond to both side surfaces of the end portion 10 a of the watch band 10.

そして、各アーム部１７の各厚肉部１７ｂに設けられたピン取付孔２１を時計バンド１０の端部１０ａの連結孔２２に対応させる。すると、ばね棒２０の一対のピン部２０ｂがコイルばね（図示せず）のばね力によって押し出されて、各アーム部１７のピン取付孔２１に挿入される。これにより、緩衝部材１６の連結部１８とばね棒２０との間に時計バンド１０を挟み付けて保持した状態で、緩衝部材１６が時計バンド１０の端部１０ａに取り付けられる。 Then, the pin mounting holes 21 provided in the respective thick portions 17b of the respective arm portions 17 are made to correspond to the connection holes 22 of the end portion 10a of the timepiece band 10. Then, the pair of pin portions 20 b of the spring bar 20 are pushed out by the spring force of a coil spring (not shown) and inserted into the pin mounting holes 21 of each arm portion 17. Thus, the buffer member 16 is attached to the end portion 10 a of the timepiece band 10 in a state where the timepiece band 10 is sandwiched and held between the connecting portion 18 of the buffer member 16 and the spring bar 20.

この後、時計バンド１０の端部１０ａを緩衝部材１６と共に腕時計ケース１に設けられたバンド取付部８の一対の取付突起部９間に配置する。このときには、緩衝部材１６の各アーム部１７における各薄肉部１７ａを一対の取付突起部９の各本体突起部９ａと時計バンド１０の端部１０ａの両側面との間に配置させて、各薄肉部１７ａの各アーム取付孔１９、一対の取付突起部９の各取付孔１２、および時計バンド１０の端部１０ａのピン挿入孔１５を同一軸上に対応させる。 Thereafter, the end portion 10 a of the watch band 10 is disposed between the pair of attachment protrusions 9 of the band attachment portion 8 provided in the watch case 1 together with the buffer member 16. At this time, each thin portion 17a in each arm portion 17 of the buffer member 16 is disposed between each main body projection portion 9a of the pair of attachment projection portions 9 and both side surfaces of the end portion 10a of the watch band 10, and each thin wall portion 17a is disposed. Each arm mounting hole 19 of the portion 17a, each mounting hole 12 of the pair of mounting projections 9, and the pin insertion hole 15 of the end 10a of the watch band 10 are made to correspond on the same axis.

そして、連結部材１１によって時計バンド１０を緩衝部材１６と共に腕時計ケース１のバンド取付部８に取り付ける。このときには、連結部材１１の第１ねじ部１３を一対の取付突起部９の各取付孔１２の一方から緩衝部材１６の一方のアーム部１７のアーム取付孔１９に挿入させ、この挿入した第１ねじ部１３の雌ねじ部１３ａを時計バンド１０のピン挿入孔１５、緩衝部材１６の他方のアーム部１７のアーム取付孔１９、および一対の取付突起部９の各取付孔１２の他方に挿入させる。 Then, the watch band 10 is attached to the band attaching portion 8 of the watch case 1 together with the buffer member 16 by the connecting member 11. At this time, the first screw portion 13 of the connecting member 11 is inserted into the arm mounting hole 19 of one arm portion 17 of the buffer member 16 from one of the mounting holes 12 of the pair of mounting projections 9, and this inserted first The female screw portion 13 a of the screw portion 13 is inserted into the other of the pin insertion hole 15 of the timepiece band 10, the arm attachment hole 19 of the other arm portion 17 of the buffer member 16, and the attachment holes 12 of the pair of attachment protrusions 9.

この状態で、連結部材１１の第２ねじ部１４の雄ねじ部１４ａを第１ねじ部１３の雌ねじ部１３ａに螺合させて締め付ける。これにより、緩衝部材１６の各アーム部１７の各薄肉部１７ａが、時計バンド１０の端部１０ａの両側面とバンド取付部８の各本体突起部９ａとの間に、弾力をもって押し付けられ、この状態で時計バンド１０の端部１０ａが緩衝部材１６と共に腕時計ケース１のバンド取付部８に取り付けられる。 In this state, the male screw portion 14a of the second screw portion 14 of the connecting member 11 is screwed into the female screw portion 13a of the first screw portion 13 and tightened. Thereby, each thin portion 17a of each arm portion 17 of the buffer member 16 is elastically pressed between both side surfaces of the end portion 10a of the watch band 10 and each main body projection portion 9a of the band attachment portion 8, In this state, the end portion 10 a of the watch band 10 is attached to the band attaching portion 8 of the watch case 1 together with the buffer member 16.

このように時計バンド１０が取り付けられた腕時計ケース１がその裏面を下に向けて落下した際には、その落下による衝撃によって時計バンド１０が連結部材１１を中心に押し広げられるように回転する。このときには、緩衝部材１６も時計バンド１０と共に回転し、この緩衝部材１６によって落下による衝撃が緩和される。 Thus, when the watch case 1 to which the watch band 10 is attached falls with its back surface facing downward, the watch band 10 rotates so as to be spread around the connecting member 11 due to the impact caused by the fall. At this time, the shock-absorbing member 16 also rotates together with the watch band 10, and the shock due to dropping is mitigated by the shock-absorbing member 16.

すなわち、図４に示す状態で、時計バンド１０が連結部材１１を中心に押し広げられるように回転する際には、緩衝部材１６がその連結部１８とばね棒２０との間に時計バンド１０を挟んで保持しているので、時計バンド１０と共に緩衝部材１６も連結部材１１を中心に回転する。 That is, in the state shown in FIG. 4, when the watch band 10 is rotated so as to be spread around the connecting member 11, the buffer member 16 places the watch band 10 between the connecting portion 18 and the spring bar 20. Since the holding member 16 is sandwiched and held, the buffer member 16 also rotates around the connecting member 11 together with the watch band 10.

このときには、緩衝部材１６の各アーム部１７における各薄肉部１７ａが一対の取付突起部９の各本体突起部９ａと時計バンド１０の端部１０ａにおける両側面との間に挟まれ、この状態で各アーム部１７の各薄肉部１７ａが連結部材１１を中心に回転するので、制動部２５によって緩衝部材１６の回転が制動される。 At this time, each thin portion 17a in each arm portion 17 of the buffer member 16 is sandwiched between each main body projection portion 9a of the pair of attachment projection portions 9 and both side surfaces of the end portion 10a of the watch band 10, and in this state Since each thin portion 17 a of each arm portion 17 rotates around the connecting member 11, the rotation of the buffer member 16 is braked by the braking portion 25.

すなわち、この制動部２５は、時計バンド１０が連結部材１１を中心に押し広げられる方向に回転する際に、各アーム部１７の各第１傾斜部２５ａが一対の取付突起部９における各本体突起部９ａの各第２傾斜部２５ｂに沿って徐々に押し付けられながら圧接摺動する。このため、緩衝部材１６の回転が徐々に重くなり、これに伴って時計バンド１０の回転も重くなる。 That is, when the watch band 10 rotates in a direction in which the timepiece band 10 is pushed and spread around the connecting member 11, the first inclined portions 25 a of the arm portions 17 are the main body protrusions of the pair of attachment protrusions 9. While being gradually pressed along the respective second inclined portions 25b of the portion 9a, they slide against each other. For this reason, the rotation of the buffer member 16 is gradually increased, and the rotation of the watch band 10 is also increased accordingly.

これにより、緩衝部材１６の回転が制動部２５によって制動されると共に、この緩衝部材１６によって時計バンド１０の回転も制動される。このため、落下による衝撃が制動部２５の制動によって緩衝され、時計バンド１０や腕時計ケース１に対する衝撃による影響が大幅に軽減される。 As a result, the rotation of the buffer member 16 is braked by the braking unit 25, and the rotation of the timepiece band 10 is also braked by the buffer member 16. For this reason, the impact due to the fall is buffered by the braking of the braking portion 25, and the influence of the impact on the watch band 10 and the watch case 1 is greatly reduced.

また、落下による衝撃によって時計バンド１０が連結部材１１を中心に押し広げられるように回転した際には、各アーム部１７の薄肉部１７ａにおける上側に位置する規制突起部２３ａがケース本体２の当接突起部２３ｃに上側から当接する。これにより、緩衝部材１６の押し上げ方向への回転が規制され、時計バンド１０の回転が規制される。このため、緩衝部材１６と時計バンド１０とが連結部材１１を中心に必要以上に回転するのを防ぐことができる。 In addition, when the watch band 10 is rotated so as to be pushed and spread around the connecting member 11 due to an impact caused by dropping, the restricting protrusion 23 a located on the upper side of the thin portion 17 a of each arm portion 17 is not contacted with the case body 2. It contacts the contact projection 23c from above. Thereby, the rotation of the buffer member 16 in the push-up direction is restricted, and the rotation of the watch band 10 is restricted. For this reason, it is possible to prevent the buffer member 16 and the watch band 10 from rotating more than necessary around the connecting member 11.

このように、この腕時計のバンド取付構造によれば、バンド取付部８が設けられた腕時計ケース１と、この腕時計ケース１のバンド取付部８に端部１０ａが配置される時計バンド１０と、この時計バンド１０の端部１０ａを保持してバンド取付部８に配置される緩衝部材１６と、時計バンド１０の端部１０ａおよび緩衝部材１６をバンド取付部８に回転可能に取り付ける連結部材１１と、を備えていることにより、落下などの衝撃を緩和して、時計バンド１０や腕時計ケース１に対する衝撃による影響を軽減することができる。 Thus, according to the wristband mounting structure of this wristwatch, the wristwatch case 1 provided with the band mounting portion 8, the watchband 10 having the end portion 10 a disposed on the band mounting portion 8 of the wristwatch case 1, A buffer member 16 that holds the end portion 10a of the watch band 10 and is disposed on the band attaching portion 8; a connecting member 11 that rotatably attaches the end portion 10a and the buffer member 16 of the watch band 10 to the band attaching portion 8; By providing, it is possible to alleviate the impact such as dropping and to reduce the influence of the impact on the watch band 10 and the watch case 1.

すなわち、このバンド取付構造では、腕時計ケース１がその裏面を下に向けて落下して、その衝撃が時計バンド１０の端部１０ａおよびこの端部１０ａを保持する緩衝部材１６に加わった際に、その衝撃を緩衝部材１６によって緩衝することができるので、時計バンド１０や腕時計ケース１に対する衝撃による影響を軽減することができる。 That is, in this band mounting structure, when the wristwatch case 1 falls with its back surface facing downward, and the impact is applied to the end portion 10a of the watch band 10 and the buffer member 16 holding the end portion 10a, Since the shock can be buffered by the buffer member 16, the influence of the shock on the watch band 10 and the watch case 1 can be reduced.

この場合、緩衝部材１６は、腕時計ケース１のバンド取付部８における一対の取付突起部９に対向する一対のアーム部１７と、これら一対のアーム部１７の各端部を連結する連結部１８とを有し、これらがバンド取付部８から斜め下側に向けて突出しているので、時計バンド１０をバンド取付部８から斜め下側に向けてガイドすることができると共に、落下などの衝撃を緩衝部材１６によって腕時計ケース１よりも先に時計バンド１０と共に受け止めることができる。 In this case, the buffer member 16 includes a pair of arm portions 17 facing the pair of mounting projections 9 in the band mounting portion 8 of the watch case 1, and a connecting portion 18 that connects each end of the pair of arm portions 17. Since these protrude from the band mounting portion 8 toward the diagonally lower side, the watch band 10 can be guided from the band mounting portion 8 toward the diagonally lower side, and shocks such as dropping can be buffered. The member 16 can be received together with the watch band 10 before the watch case 1.

また、この緩衝部材１６は、その連結部１８とばね棒２０との間に時計バンド１０を挟んで保持しているので、落下による衝撃によって時計バンド１０が連結部材１１を中心に押し広げられるように回転する際に、緩衝部材１６を時計バンド１０と共に回転させることができ、これにより緩衝部材１６の回転によって衝撃を緩和することができる。この場合、緩衝部材１６は、その各アーム部１７および連結部１８が時計バンド１０の上面側に露呈するので、デザイン的なアクセントとなり、外観的にもデザイン的にも好ましいものを提供できる。 Further, since the buffer member 16 holds the watch band 10 between the connecting portion 18 and the spring bar 20, the watch band 10 is pushed and spread around the connecting member 11 by an impact caused by dropping. When rotating, the shock-absorbing member 16 can be rotated together with the watch band 10, whereby the shock can be mitigated by the rotation of the shock-absorbing member 16. In this case, since each arm part 17 and the connection part 18 are exposed to the upper surface side of the timepiece band 10, the buffer member 16 becomes a design accent and can provide what is preferable in terms of appearance and design.

また、この緩衝部材１６は、ポリアミド（ＰＡ）などの剛性が高く、かつ弾力性を有する合成樹脂で形成されていることにより、バンド取付部８の一対の取付突起部９と時計バンド１０の端部１０ａの両側面との間に配置される各アーム部１７に各薄肉部１７ａを形成しても、各薄肉部１７ａの強度を確保することができ、これにより耐衝撃性を高めることができる。 The buffer member 16 is made of a synthetic resin having high rigidity such as polyamide (PA) and having elasticity, so that the pair of mounting projections 9 of the band mounting portion 8 and the end of the watch band 10 are Even if each thin portion 17a is formed on each arm portion 17 disposed between both side surfaces of the portion 10a, the strength of each thin portion 17a can be secured, thereby improving the impact resistance. .

また、このバンド取付構造では、連結部材１１を中心に緩衝部材１６がバンド取付部８に対して回転する際に、バンド取付部８に対する緩衝部材１６の回転を制動する制動部２５を備えていることにより、衝撃によって時計バンド１０が連結部材１１を中心に押し広げられる方向に回転するときに、この時計バンド１０に伴って緩衝部材１６が回転するため、この緩衝部材１６の回転を制動部２５によって良好に制動することができるので、この制動部２５によって衝撃を確実にかつ良好に緩衝することができる。 Further, this band mounting structure includes a braking portion 25 that brakes the rotation of the buffer member 16 with respect to the band mounting portion 8 when the buffer member 16 rotates with respect to the band mounting portion 8 around the connecting member 11. As a result, when the watch band 10 rotates in a direction in which the watch band 10 is pushed and spread around the connecting member 11 due to an impact, the buffer member 16 rotates along with the watch band 10. Therefore, the braking can be reliably and satisfactorily buffered by the braking portion 25.

この場合、制動部２５は、各アーム部１７の各薄肉部１７ａと各厚肉部１７ｂとの境界部に設けられた各第１傾斜部２５ａと、これら各第１傾斜部２５ａが対面する一対の取付突起部９における各本体突起部９ａの個所に設けられて各第１傾斜部２５ａが接離可能に圧接摺動するオーバーハング形状の各第２傾斜部２５ｂと、を備えている構成であることにより、衝撃による緩衝部材１６の回転を確実にかつ良好に制動することができる。 In this case, the braking portion 25 includes a first inclined portion 25a provided at a boundary portion between each thin portion 17a and each thick portion 17b of each arm portion 17, and a pair of the first inclined portions 25a facing each other. Each mounting projection 9 is provided with a portion of each main body projection 9a, and each second inclined portion 25b having an overhang shape in which each first inclined portion 25a is slidably pressed and slidable is provided. As a result, it is possible to reliably and satisfactorily brake the rotation of the buffer member 16 due to the impact.

すなわち、この制動部２５は、衝撃によって緩衝部材１６が回転する際に、各アーム部１７の各第１傾斜部２５ａが一対の取付突起部９の各第２傾斜部２５に沿って徐々に押し付けられながら圧接摺動するため、緩衝部材１６の回転を徐々に重くし、これに伴って時計バンド１０の回転も重くすることができる。これにより、緩衝部材１６の回転を確実に制動することができるので、落下による衝撃を確実にかつ良好に緩和することができ、時計バンド１０や腕時計ケース１に対する衝撃の影響を大幅に軽減することができる。 That is, when the buffer member 16 is rotated by an impact, the braking portion 25 gradually presses the first inclined portions 25a of the arm portions 17 along the second inclined portions 25 of the pair of attachment projections 9. Since the pressure member slides while being pressed, the rotation of the buffer member 16 can be gradually increased, and the rotation of the watch band 10 can be increased accordingly. Thereby, since the rotation of the buffer member 16 can be reliably braked, the impact caused by the fall can be surely and satisfactorily reduced, and the influence of the impact on the watch band 10 and the watch case 1 can be greatly reduced. Can do.

また、このバンド取付構造は、図８〜図１０に示すように、連結部材１１を中心に緩衝部材３０が回転する際に、その回転範囲を規制する回転規制部３５を備えている。この回転規制部３５は、緩衝部材３０の各アーム部３１における各厚肉部３１ｂの各先端部に設けられた各規制部３５ａと、一対の取付突起部９の各ケース本体２に設けられ、各規制部３５ａが回転移動して制動部３４による制動力が最大になった際に当接する当接部３５ｂと、を備えている。 Further, as shown in FIGS. 8 to 10, the band mounting structure includes a rotation restricting portion 35 that restricts the rotation range when the buffer member 30 rotates around the connecting member 11. The rotation restricting portion 35 is provided in each restricting portion 35a provided at each distal end portion of each thick portion 31b in each arm portion 31 of the buffer member 30, and in each case body 2 of the pair of attachment projections 9, Each regulating portion 35a includes a contact portion 35b that contacts when the braking force by the braking portion 34 is maximized by rotational movement.

これにより、回転規制部３５は、図８〜図１０に示すように、連結部材１１を中心に緩衝部材３０が時計バンド１０の端部１０ａと共に押し上げられる方向（図１０において反時計回り方向）に回転した際に、各アーム部３１の各厚肉部３１ｂの上端部に位置する規制部３５ａがケース本体２の当接部３５ｂに当接することにより、緩衝部材３０の押し上げ方向への回転を規制して、時計バンド１０の回転を規制するように構成されている。 Thereby, as shown in FIGS. 8 to 10, the rotation restricting portion 35 moves in a direction (counterclockwise direction in FIG. 10) in which the buffer member 30 is pushed up together with the end portion 10 a of the watch band 10 around the connecting member 11. When rotating, the restricting portion 35a located at the upper end of each thick portion 31b of each arm portion 31 abuts against the abutting portion 35b of the case body 2, thereby restricting the rotation of the buffer member 30 in the push-up direction. Thus, the rotation of the watch band 10 is restricted.

次に、このような腕時計におけるバンド取付構造の作用について説明する。
まず、腕時計ケース１に時計バンド１０を取り付ける場合には、予め、時計バンド１０の端部１０ａを緩衝部材３０の連結部３２に設けられたバンド挿入孔３２ａに挿入させて、緩衝部材３０の各アーム部３１を時計バンド１０の端部１０ａの両側面に対応させる。 Next, the operation of the band mounting structure in such a wristwatch will be described.
First, when attaching the watch band 10 to the watch case 1, the end 10 a of the watch band 10 is inserted in advance into the band insertion hole 32 a provided in the connecting portion 32 of the buffer member 30, and each of the buffer members 30. The arm portion 31 is made to correspond to both side surfaces of the end portion 10a of the watch band 10.

そして、時計バンド１０の端部１０ａを緩衝部材３０と共に腕時計ケース１に設けられたバンド取付部８の一対の取付突起部９間に配置する。このときには、緩衝部材３０の各アーム部３１における各薄肉部３１ａを一対の取付突起部９の各本体突起部９ａと時計バンド１０の端部１０ａの両側面との間に配置させて、各薄肉部３１ａの各アーム取付孔３３、一対の取付突起部９の各取付孔１２、および時計バンド１０の端部１０ａのピン挿入孔１５を同一軸上に対応させる。 Then, the end portion 10 a of the watch band 10 is disposed between the pair of attachment protrusions 9 of the band attachment portion 8 provided in the watch case 1 together with the buffer member 30. At this time, each thin portion 31a in each arm portion 31 of the buffer member 30 is disposed between each main body projection portion 9a of the pair of attachment projection portions 9 and both side surfaces of the end portion 10a of the watch band 10, and each thin wall portion 31a is disposed. Each arm mounting hole 33 of the portion 31a, each mounting hole 12 of the pair of mounting projections 9, and the pin insertion hole 15 of the end 10a of the watch band 10 are made to correspond on the same axis.

この状態で、連結部材１１によって時計バンド１０を緩衝部材３０と共に腕時計ケース１のバンド取付部８に取り付ける。このときには、連結部材１１の第１ねじ部１３を一対の取付突起部９の各取付孔１２の一方から緩衝部材３０の一方のアーム部３１のアーム取付孔３３に挿入させ、この挿入した第１ねじ部１３の雌ねじ部１３ａを時計バンド１０のピン挿入孔１５、緩衝部材３０の他方のアーム部３１のアーム取付孔３３、および一対の取付突起部９の各取付孔１２の他方に挿入させる。 In this state, the watch band 10 is attached to the band attaching portion 8 of the watch case 1 together with the buffer member 30 by the connecting member 11. At this time, the first screw portion 13 of the connecting member 11 is inserted into the arm attachment hole 33 of one arm portion 31 of the buffer member 30 from one of the attachment holes 12 of the pair of attachment projections 9, and this inserted first The female screw portion 13 a of the screw portion 13 is inserted into the other of the pin insertion hole 15 of the timepiece band 10, the arm attachment hole 33 of the other arm portion 31 of the buffer member 30, and the attachment holes 12 of the pair of attachment protrusions 9.

そして、連結部材１１の第２ねじ部１４の雄ねじ部１４ａを第１ねじ部１３の雌ねじ部１３ａに螺合させて締め付ける。すると、緩衝部材３０の各アーム部３１の各薄肉部３１ａが時計バンド１０の端部１０ａの両側面によってバンド取付部８の各本体突起部９ａに挟み付けられる。これにより、時計バンド１０の端部１０ａが緩衝部材３０と共に腕時計ケース１のバンド取付部８に取り付けられる。 Then, the male screw portion 14 a of the second screw portion 14 of the connecting member 11 is screwed into the female screw portion 13 a of the first screw portion 13 and tightened. Then, each thin portion 31 a of each arm portion 31 of the buffer member 30 is sandwiched between each main body projection 9 a of the band attachment portion 8 by both side surfaces of the end portion 10 a of the timepiece band 10. As a result, the end portion 10 a of the watch band 10 is attached to the band attaching portion 8 of the watch case 1 together with the buffer member 30.

このように時計バンド１０が取り付けられた腕時計ケース１がその裏面を下に向けて落下した際には、その落下による衝撃によって時計バンド１０が連結部材１１を中心に押し広げられるように回転する。このときには、緩衝部材３０も時計バンド１０と共に回転し、この緩衝部材３０によって落下による衝撃が緩和される。 Thus, when the watch case 1 to which the watch band 10 is attached falls with its back surface facing downward, the watch band 10 rotates so as to be spread around the connecting member 11 due to the impact caused by the fall. At this time, the shock-absorbing member 30 also rotates together with the watch band 10, and the shock due to dropping is relieved by the shock-absorbing member 30.

すなわち、時計バンド１０が連結部材１１を中心に押し広げられるように回転する際には、緩衝部材３０の連結部３２のバンド挿入孔３２ａに時計バンド１０の端部１０ａが挿入されていることにより、緩衝部材３０が時計バンド１０を保持しているので、時計バンド１０と共に緩衝部材３０も連結部材１１を中心に回転する。 That is, when the watch band 10 rotates so as to be spread around the connecting member 11, the end portion 10 a of the watch band 10 is inserted into the band insertion hole 32 a of the connecting portion 32 of the buffer member 30. Since the buffer member 30 holds the watch band 10, the buffer member 30 also rotates about the connecting member 11 together with the watch band 10.

このときには、緩衝部材３０の各アーム部３１における各薄肉部３１ａが、一対の取付突起部９の各本体突起部９ａと時計バンド１０の端部１０ａにおける両側面との間に挟まれ、この状態で各アーム部３１の各薄肉部３１ａが連結部材１１を中心に図１０において反時計回り方向に回転するので、制動部３４によって緩衝部材３０の回転が制動される。 At this time, each thin portion 31a in each arm portion 31 of the buffer member 30 is sandwiched between each main body projection portion 9a of the pair of attachment projection portions 9 and both side surfaces of the end portion 10a of the watch band 10, and this state Thus, each thin portion 31a of each arm portion 31 rotates in the counterclockwise direction in FIG. 10 around the connecting member 11, so that the rotation of the buffer member 30 is braked by the braking portion 34.

すなわち、この制動部３４は、時計バンド１０が連結部材１１を中心に押し広げられる方向（図１０において反時計回り方向）に回転する際に、各アーム部３１の各第１傾斜部３４ａが一対の取付突起部９の各第２傾斜部３４ｂに沿って徐々に押し付けられながら圧接摺動する。このため、緩衝部材３０の回転が徐々に重くなり、これに伴って時計バンド１０の回転も重くなる。 In other words, the braking portion 34 has a pair of the first inclined portions 34a of the arm portions 31 when the watch band 10 rotates in the direction in which the watch band 10 is spread about the connecting member 11 (counterclockwise direction in FIG. 10). The attachment projection 9 is pressed and slid while being gradually pressed along the second inclined portions 34b. For this reason, the rotation of the buffer member 30 gradually increases, and the rotation of the watch band 10 also increases accordingly.

これにより、緩衝部材３０の回転が制動部３４によって制動されると共に、この緩衝部材３０によって時計バンド１０の回転も制動される。このため、落下による衝撃が制動部３４の制動によって緩衝され、時計バンド１０や腕時計ケース１に対する衝撃による影響が大幅に軽減される。 As a result, the rotation of the buffer member 30 is braked by the brake unit 34, and the rotation of the timepiece band 10 is also braked by the buffer member 30. For this reason, the impact due to the fall is buffered by the braking of the braking portion 34, and the influence of the impact on the watch band 10 and the watch case 1 is greatly reduced.

また、落下による衝撃によって時計バンド１０が連結部材１１を中心に押し広げられるように回転した際には、回転規制部３５によって緩衝部材３０の回転が規制される。すなわち、制動部３４による制動力が最大になった際に、各アーム部３１の各厚肉部３１ｂの上端部に位置する規制部３５ａがケース本体２の当接部３５ｂに当接する。 Further, when the watch band 10 is rotated so as to be pushed and spread around the connecting member 11 due to an impact caused by dropping, the rotation of the buffer member 30 is restricted by the rotation restricting portion 35. That is, when the braking force by the braking portion 34 becomes maximum, the restricting portion 35 a located at the upper end portion of each thick portion 31 b of each arm portion 31 comes into contact with the contact portion 35 b of the case body 2.

これにより、緩衝部材３０の押し上げ方向への回転が規制されて、時計バンド１０の回転が規制される。このため、緩衝部材３０と時計バンド１０とが連結部材１１を中心に必要以上に回転するのを防ぐことができる。この後は、緩衝部材３０が弾力性を有する合成樹脂で形成されているので、制動部３４の第２傾斜部３４ｂに圧接している緩衝部材３０の第１傾斜部３４ａが弾性復帰し、これにより緩衝部材３０が初期位置に向けて回転して元の位置に戻る。 Thereby, the rotation of the buffer member 30 in the push-up direction is restricted, and the rotation of the timepiece band 10 is restricted. For this reason, it is possible to prevent the buffer member 30 and the watch band 10 from rotating more than necessary around the connecting member 11. Thereafter, since the buffer member 30 is formed of a synthetic resin having elasticity, the first inclined portion 34a of the buffer member 30 that is in pressure contact with the second inclined portion 34b of the brake portion 34 is elastically restored, Thus, the buffer member 30 rotates toward the initial position and returns to the original position.

このように、この第２実施形態における腕時計のバンド取付構造によれば、バンド取付部８が設けられた腕時計ケース１と、この腕時計ケース１のバンド取付部８に端部１０ａが配置される時計バンド１０と、この時計バンド１０の端部１０ａを保持してバンド取付部８に配置される緩衝部材３０と、時計バンド１０の端部１０ａおよび緩衝部材３０をバンド取付部８に回転可能に取り付ける連結部材１１と、を備えていることにより、第１実施形態と同様、落下などの衝撃を緩和して、時計バンド１０や腕時計ケース１に対する衝撃による影響を軽減することができる。 Thus, according to the wristband mounting structure of the wristwatch according to the second embodiment, the wristwatch case 1 provided with the band mounting portion 8 and the timepiece in which the end portion 10a is disposed on the band mounting portion 8 of the wristwatch case 1. The band 10, the buffer member 30 that holds the end portion 10 a of the watch band 10 and is disposed on the band attaching portion 8, and the end portion 10 a and the buffer member 30 of the watch band 10 are rotatably attached to the band attaching portion 8. By providing the connecting member 11, as in the first embodiment, it is possible to mitigate an impact such as a drop and reduce the influence of the impact on the watch band 10 and the watch case 1.

すなわち、このバンド取付構造では、腕時計ケース１がその裏面を下に向けて落下して、その衝撃が時計バンド１０の端部１０ａおよびこの端部１０ａを保持する緩衝部材３０に加わった際に、第１実施形態と同様、その衝撃を緩衝部材３０によって緩衝することができるので、時計バンド１０や腕時計ケース１に対する衝撃による影響を軽減することができる。 That is, in this band mounting structure, when the wristwatch case 1 falls with its back surface facing down, and the impact is applied to the end portion 10a of the watch band 10 and the buffer member 30 holding the end portion 10a, As in the first embodiment, the shock can be buffered by the buffer member 30, so that the influence of the shock on the watch band 10 and the watch case 1 can be reduced.

この場合、緩衝部材３０は、腕時計ケース１のバンド取付部８における一対の取付突起部９に対向する一対のアーム部３１と、これら一対のアーム部３１の各端部を連結する連結部３２とを有し、これらがバンド取付部８から斜め下側に向けて突出しているので、第１実施形態と同様、時計バンド１０をバンド取付部８から斜め下側に向けてガイドすることができると共に、落下などの衝撃を腕時計ケース１よりも先に時計バンド１０と共に受け止めることができる。 In this case, the buffer member 30 includes a pair of arm portions 31 opposed to the pair of attachment projections 9 in the band attachment portion 8 of the watch case 1, and a connection portion 32 that connects each end portion of the pair of arm portions 31. Since these protrude from the band attaching portion 8 toward the obliquely lower side, the watch band 10 can be guided obliquely downward from the band attaching portion 8 as in the first embodiment. The impact such as dropping can be received together with the watch band 10 before the watch case 1.

また、この緩衝部材３０は、その連結部３２にバンド取付孔３２が設けられ、このバンド取付孔３２ａに時計バンド１０を挿入させることにより、時計バンド１０を保持しているので、第１実施形態と同様、落下による衝撃によって時計バンド１０が連結部材１１を中心に押し広げられるように回転する際に、緩衝部材３０を時計バンド１０と共に回転させることができ、の緩衝部材３０の回転によって衝撃を緩和することができる。 Further, the buffer member 30 is provided with a band attachment hole 32 in the connecting portion 32, and the watch band 10 is held by inserting the watch band 10 into the band attachment hole 32a. Similarly, when the watch band 10 is rotated so that the watch band 10 is pushed and spread around the connecting member 11 due to an impact caused by dropping, the buffer member 30 can be rotated together with the watch band 10, and the shock is applied by the rotation of the buffer member 30. Can be relaxed.

この場合にも、緩衝部材３０は、第１実施形態と同様、ポリアミド（ＰＡ）などの剛性が高く、かつ弾力性を有する合成樹脂で形成されていることにより、バンド取付部８の一対の取付突起部９と時計バンド１０の端部１０ａの両側面との間に配置される各アーム部３１に各薄肉部３１ａを形成しても、各薄肉部３１ａの強度を確保することができ、これにより各薄肉部３１ａに制動部３４の第１傾斜部３４ａを設けて、緩衝部材３０の回転を良好に制動することができる。 Also in this case, the buffer member 30 is formed of a synthetic resin having high rigidity and elasticity such as polyamide (PA), as in the first embodiment, so that a pair of attachments of the band attachment portion 8 is achieved. Even if each thin portion 31a is formed on each arm portion 31 disposed between the protruding portion 9 and both side surfaces of the end portion 10a of the watch band 10, the strength of each thin portion 31a can be secured. Accordingly, the first inclined portion 34a of the braking portion 34 can be provided in each thin portion 31a, so that the rotation of the buffer member 30 can be satisfactorily braked.

また、このバンド取付構造では、連結部材１１を中心に緩衝部材３０がバンド取付部８に対して回転する際に、バンド取付部８に対する緩衝部材３０の回転を制動する制動部３４を備えていることにより、衝撃によって時計バンド１０が連結部材１１を中心に押し広げられる方向に回転するときに、この時計バンド１０に伴って緩衝部材３０が回転するため、この緩衝部材３０の回転を制動部３４によって良好に制動することができるので、この制動部３４によって衝撃を緩衝することができる。 Further, this band mounting structure includes a braking portion 34 that brakes the rotation of the buffer member 30 with respect to the band mounting portion 8 when the buffer member 30 rotates with respect to the band mounting portion 8 around the connecting member 11. As a result, when the watch band 10 is rotated in a direction in which the watch band 10 is pushed and spread around the connecting member 11 due to an impact, the buffer member 30 rotates with the watch band 10. Therefore, it is possible to satisfactorily brake, so that the shock can be buffered by the braking portion 34.

この場合、制動部３４は、連結部材１１の周囲近傍に位置する個所の緩衝部材３０の各アーム部３１に設けられた第１傾斜部３４ａと、連結部材１１の周囲近傍に位置する個所のバンド取付部８の一対の取付突起部９に設けられて第１傾斜部３４ａが接離可能に圧接摺動するオーバーハング形状の第２傾斜部３４ｂとを備えている構成であることにより、衝撃による緩衝部材３０の回転を確実にかつ良好に制動することができる。 In this case, the braking portion 34 includes a first inclined portion 34 a provided on each arm portion 31 of the buffer member 30 at a location near the periphery of the connecting member 11, and a band at a location positioned near the periphery of the connecting member 11. By being provided with a pair of mounting protrusions 9 of the mounting portion 8 and having a second inclined portion 34b having an overhang shape in which the first inclined portion 34a is slidably pressed and slidable, The rotation of the buffer member 30 can be reliably and satisfactorily braked.

すなわち、この制動部３４は、衝撃によって緩衝部材３０が回転する際に、各アーム部３１の各第１傾斜部３４ａが一対の取付突起部９の各第２傾斜部３４ｂに沿って徐々に押し付けられながら圧接摺動するため、緩衝部材３０の回転を徐々に重くし、これに伴って時計バンド１０の回転も重くすることができる。これにより、緩衝部材３０の回転を確実に制動することができるので、落下による衝撃を確実にかつ良好に緩和することができ、時計バンド１０や腕時計ケース１に対する衝撃の影響を大幅に軽減することができる。 That is, when the shock absorbing member 30 is rotated by an impact, the braking portion 34 gradually presses the first inclined portions 34a of the arm portions 31 along the second inclined portions 34b of the pair of attachment projections 9. Since the pressure member slides while being pressed, the rotation of the buffer member 30 can be gradually increased, and the rotation of the watch band 10 can be increased accordingly. As a result, the rotation of the buffer member 30 can be reliably braked, so that the impact caused by dropping can be reliably and satisfactorily reduced, and the influence of the impact on the watch band 10 and the watch case 1 can be greatly reduced. Can do.

なお、上述した第２実施形態では、緩衝部材３０の各アーム部３１に設けられた第１傾斜部３４ａと、バンド取付部８の一対の取付突起部９に設けられた第２傾斜部３４ｂとによって、制動部３４を構成した場合について述べたが、これに限らず、例えば図１３〜図１５に示す変形例のように構成しても良い。 In the second embodiment described above, the first inclined portion 34 a provided on each arm portion 31 of the buffer member 30, and the second inclined portion 34 b provided on the pair of attachment projections 9 of the band attachment portion 8. However, the present invention is not limited to this. For example, the brake unit 34 may be configured as in the modified examples shown in FIGS.

すなわち、この変形例の制動部４０は、図１３〜図１５に示すように、連結部材１１の周囲近傍に位置する個所の緩衝部材３０の各アーム部３１にそれぞれ設けられて緩やかに傾斜する山形形状の第１突起部４０ａと、連結部材１１の周囲近傍に位置する個所のバンド取付部８の一対の取付突起部９にそれぞれ設けられて第１突起部４０ａが接離可能に乗り上げて圧接する緩やかに傾斜する山形形状の第２突起部４０ｂとを備えている。 That is, as shown in FIG. 13 to FIG. 15, the braking portion 40 of this modification is provided in each arm portion 31 of the buffer member 30 at a location near the periphery of the connecting member 11 and is gently inclined. The first protrusion 40a having a shape and the pair of attachment protrusions 9 of the band attachment part 8 located in the vicinity of the periphery of the connecting member 11 are mounted on the first protrusion 40a so as to be able to come into contact with and separated from each other. And a mountain-shaped second protrusion 40b that is gently inclined.

この場合、第１突起部４０ａは、図１３および図１５（ａ）に示すように、各アーム部３１の各薄肉部３１ａにそれぞれ一対の取付突起部９に向けて突出して設けられている。また、第２突起部４０ｂは、図１３および図１５（ｂ）に示すように、一対の取付突起部９の各本体突起部９ａにそれぞれ各アーム部３１の各薄肉部３１ａに向けて突出して設けられている。 In this case, as shown in FIG. 13 and FIG. 15A, the first protrusions 40 a are provided on the respective thin portions 31 a of the respective arm portions 31 so as to protrude toward the pair of attachment protrusions 9. Further, as shown in FIGS. 13 and 15B, the second protrusions 40b protrude from the main body protrusions 9a of the pair of attachment protrusions 9 toward the thin portions 31a of the arm parts 31, respectively. Is provided.

これにより、この制動部４０は、図１３〜図１５に示すように、時計バンド１０が連結部材１１を中心に押し広げられる方向に回転する際に、各アーム部３１の各第１突起部４０ａが一対の取付突起部９の各第２突起部４０ｂに徐々に乗り上げながら圧接摺動することにより、緩衝部材３０の回転を徐々に重くするように制動すると共に、時計バンド１０の回転をも制動するように構成されている。 As a result, as shown in FIGS. 13 to 15, the braking portion 40 is configured so that each first protrusion 40 a of each arm portion 31 is rotated when the timepiece band 10 rotates in a direction in which the timepiece band 10 is pushed and spread around the connecting member 11. , While gradually climbing on the second protrusions 40b of the pair of attachment protrusions 9, the brake member 30 is braked so as to gradually increase the rotation of the buffer member 30, and the rotation of the watch band 10 is also braked. Is configured to do.

このような変形例のバンド取付構造によれば、衝撃によって緩衝部材３０が回転する際に、各アーム部３１の各第１突起部４０ａが一対の取付突起部９の各第２突起部４０ｂに徐々に乗り上げて押し合いながら圧接摺動するため、緩衝部材３０の回転を制動部４０によって徐々に重くし、これに伴って時計バンド１０の回転も重くすることができる。 According to the band mounting structure of such a modification, when the buffer member 30 is rotated by an impact, each first protrusion 40a of each arm 31 is moved to each second protrusion 40b of the pair of mounting protrusions 9. Since the pressure member slides while gradually climbing and pushing against each other, the rotation of the buffer member 30 is gradually increased by the braking unit 40, and accordingly, the rotation of the watch band 10 can also be increased.

これにより、このバンド取付構造においても、第２実施形態と同様、緩衝部材３０の回転を制動部４０によって確実にかつ良好に制動することができるので、落下による衝撃を確実にかつ良好に緩和することができる。このため、時計バンド１０や腕時計ケース１に対する衝撃による影響を大幅に軽減することができる。 Thereby, also in this band mounting structure, since the rotation of the buffer member 30 can be reliably and satisfactorily braked by the braking portion 40 as in the second embodiment, the impact caused by the fall is reliably and satisfactorily mitigated. be able to. For this reason, the influence by the impact with respect to the watch band 10 or the wristwatch case 1 can be reduced significantly.

なおまた、上述した第２実施形態およびその変形例では、緩衝部材３０の連結部３２に、時計バンド１０が挿入するバンド取付孔３２ａを設けた場合について述べたが、これに限らず、例えば緩衝部材３０の連結部は、バンド取付孔３２ａの下側を開放させて、第１実施形態のように、時計バンド１０の上面のみを押えるように構成されていても良い。 In the above-described second embodiment and the modification thereof, the case where the band attachment hole 32a into which the watch band 10 is inserted is provided in the coupling portion 32 of the buffer member 30, but the present invention is not limited thereto. The connecting portion of the member 30 may be configured to open only the upper surface of the watch band 10 by opening the lower side of the band attachment hole 32a as in the first embodiment.

また、上述した第１、第２の各実施形態およびその変形例では、時計バンド１０がウレタン樹脂などの軟質の合成樹脂によって形成されている場合について述べたが、これに限らず、例えば時計バンドは金属製であっても良い。 Further, in each of the first and second embodiments described above and the modifications thereof, the case where the watch band 10 is formed of a soft synthetic resin such as urethane resin is described. May be made of metal.
