The mounting convex portion 8 is formed so that the length in the width direction orthogonal to the longitudinal direction of the band 2 is shorter than the length in the width direction of the band 2. Further, the mounting convex portion 8 is provided with a mounting hole 8a into which a connecting member 9 described later is inserted so as to penetrate in the width direction of the band 2.

一方、バンド２は、図２〜図６に示すように、バンド本体１０と補強部１１とを備えている。バンド本体１０は、後述する合成樹脂によってほぼ帯状に形成されている。すなわち、このバンド本体１０は、腕時計ケース１のバンド取付部３に取り付けられる端部１０ａの厚みがバンド取付部３側の先端側に向けて次第に厚くなる形状に形成され、この端部１０ａを除いてほぼ均一な厚さで形成されている。 On the other hand, the band 2 includes a band main body 10 and a reinforcing portion 11 as shown in FIGS. 2 to 6. The band body 10 is formed in a substantially band shape by a synthetic resin described later. That is, the band body 10 is formed so that the thickness of the end portion 10a attached to the band attachment portion 3 of the wristwatch case 1 gradually increases toward the tip end side on the band attachment portion 3 side, and the end portion 10a is excluded. It is formed with an almost uniform thickness.

補強部１１は、図２〜図７に示すように、バンド本体１０と同じ合成樹脂で、かつ後述するように、硬度がバンド本体１０の硬度よりも高い材料で形成されている。この補強部１１は、バンド本体１０の端部１０ａにインサート成型によって一体に埋め込まれている。すなわち、この補強部１１は、腕時計ケース１側の先端側がバンド本体１０の端部１０ａから露出した状態で、バンド本体１０の端部１０ａに埋め込まれている。 As shown in FIGS. 2 to 7, the reinforcing portion 11 is made of the same synthetic resin as the band body 10, and as described later, is made of a material having a hardness higher than that of the band body 10. The reinforcing portion 11 is integrally embedded in the end portion 10a of the band main body 10 by insert molding. That is, the reinforcing portion 11 is embedded in the end portion 10a of the band main body 10 with the tip end side on the wristwatch case 1 side exposed from the end portion 10a of the band main body 10.

この補強部１１は、図５および図６に示すように、バンド本体１０の端部１０ａの先端側からバンド本体１０にその長手方向に食い込むほぼ三角柱状に形成されている。すなわち、この補強部１１は、先端側の厚みが厚く、バンド本体１０の長手方向に食い込むに従って次第に厚みが薄く形成されている。 As shown in FIGS. 5 and 6, the reinforcing portion 11 is formed in a substantially triangular columnar shape that bites into the band main body 10 in the longitudinal direction from the tip end side of the end portion 10a of the band main body 10. That is, the reinforcing portion 11 has a thick tip side, and is gradually formed to become thinner as it bites into the band body 10 in the longitudinal direction.

この場合、補強部１１は、図５および図６に示すように、食込み方向の長さ、つまりバンド本体１０の長手方向における長さが、バンド本体１０の端部１０ａの先端側からバンド本体１０の厚みがほぼ均一になる箇所に亘る長さに形成されている。また、この補強部１１は、バンド本体１０の長手方向と直交する幅方向の長さが、バンド本体１０の端部１０ａの幅方向の長さよりも少し短い長さで形成されている。 In this case, as shown in FIGS. 5 and 6, the length of the reinforcing portion 11 in the biting direction, that is, the length of the band main body 10 in the longitudinal direction is the band main body 10 from the tip end side of the end portion 10a of the band main body 10. It is formed to have a length extending over a portion where the thickness of the material becomes almost uniform. Further, the reinforcing portion 11 is formed so that the length in the width direction orthogonal to the longitudinal direction of the band main body 10 is slightly shorter than the length in the width direction of the end portion 10a of the band main body 10.

この補強部１１には、図３〜図７に示すように、腕時計ケース１のバンド取付部３に設けられた取付凸部８が配置される取付凹部１２が設けられている。この取付凹部１２は、バンド本体１０の長手方向と直交する幅方向の長さが取付凸部８の長さと同じか、それよりも少し長く形成されている。また、この取付凹部１２の両側に位置する各側部１３は、断面形状がほぼ半円形状に形成されている。これら各側部１３には、一対の連結孔１４がそれぞれ取付凸部８の取付孔８ａと同一軸上に対応して設けられている。 As shown in FIGS. 3 to 7, the reinforcing portion 11 is provided with a mounting recess 12 in which the mounting convex portion 8 provided on the band mounting portion 3 of the wristwatch case 1 is arranged. The mounting recess 12 is formed so that the length in the width direction orthogonal to the longitudinal direction of the band main body 10 is the same as or slightly longer than the length of the mounting convex portion 8. Further, each side portion 13 located on both sides of the mounting recess 12 is formed to have a substantially semicircular cross-sectional shape. Each of these side portions 13 is provided with a pair of connecting holes 14 corresponding to the mounting holes 8a of the mounting convex portions 8 on the same axis.

The large-diameter hole portion 14a is formed so that the inner diameter is slightly larger than the inner diameter of the mounting hole 8a of the mounting convex portion 8, and the axial length is shorter than the axial length of the small-diameter hole portion 14b. The inner diameter of the small-diameter hole portion 14b is formed to be slightly smaller than the inner diameter of the mounting hole 8a of the mounting convex portion 8.

また、補強部１１の下面には、図２〜図７に示すように、回転止め部１５が取付凹部１２に対応した状態で、下側に突出して設けられている。この回転止め部１５は、図２に示すように、腕時計ケース１のバンド取付部３の取付凸部８が補強部１１の取付凹部１２に配置されて、補強部１１が取付凹部１２の両側に位置する各側部１３に連結部材９によって連結された状態で、連結部材９を中心に回転した際に、腕時計ケース１の裏蓋６の下面に接離可能に当接して、バンド本体１０の端部１０ａの回転を規制するように構成されている。 Further, as shown in FIGS. 2 to 7, a rotation stop portion 15 is provided on the lower surface of the reinforcing portion 11 so as to project downward in a state corresponding to the mounting recess 12. As shown in FIG. 2, in the rotation stop portion 15, the mounting convex portion 8 of the band mounting portion 3 of the wristwatch case 1 is arranged in the mounting recess 12 of the reinforcing portion 11, and the reinforcing portions 11 are provided on both sides of the mounting recess 12. When the wristwatch case 1 is rotated around the connecting member 9 in a state of being connected to each of the positioned side portions 13 by the connecting member 9, the band main body 10 is brought into contact with the lower surface of the back cover 6 of the wristwatch case 1 so as to be detachable. It is configured to regulate the rotation of the end portion 10a.

この場合、補強部１１は、図３〜図５に示すように、バンド本体１０の長手方向と直交する幅方向の両側に位置する各側部１３の外面および回転止め部１５の両側面がバンド本体１０の端部１０ａで覆われている。このため、補強部１１の各側部１３を覆ったバンド本体１０の端部１０ａには、それぞれ挿入孔１０ｂが各側部１３に設けられた一対の連結孔１４と同一軸上に対応して設けられている。この挿入孔１０ｂは、内径が側部１３の連結孔１４における大径孔部１４ａの内径とほぼ同じ大きさに形成されている。 In this case, as shown in FIGS. 3 to 5, the reinforcing portion 11 has a band on both outer surfaces of the side portions 13 and both side surfaces of the rotation stopper 15 located on both sides in the width direction orthogonal to the longitudinal direction of the band main body 10. It is covered with the end portion 10a of the main body 10. Therefore, the end portions 10a of the band main body 10 that covers each side portion 13 of the reinforcing portion 11 have insertion holes 10b corresponding to the pair of connecting holes 14 provided in each side portion 13 on the same axis. It is provided.

ところで、バンド本体１０は、フッ素樹脂、ウレタン樹脂、シリコーン樹脂などの弾力を有する合成樹脂によって形成されている。補強部１１は、バンド本体１０と同じ合成樹脂で、かつ硬度がバンド本体１０の硬度よりも高い材料で形成されている。すなわち、バンド本体１０は、フッ素樹脂の場合、JIS-A硬度が７０〜７５°であり、補強部１１は、JIS-A硬度が９０〜９５°である。これにより、補強部１１は、強度がバンド本体１０よりも高く形成されている。 By the way, the band body 10 is formed of an elastic synthetic resin such as a fluororesin, a urethane resin, or a silicone resin. The reinforcing portion 11 is made of the same synthetic resin as the band main body 10 and has a hardness higher than the hardness of the band main body 10. That is, in the case of fluororesin, the band body 10 has a JIS-A hardness of 70 to 75 °, and the reinforcing portion 11 has a JIS-A hardness of 90 to 95 °. As a result, the reinforcing portion 11 is formed to have a higher strength than the band main body 10.

この補強部１１は、図４に示すように、先端側がバンド本体１０の端部１０ａから露出した状態で、バンド本体１０の端部１０ａにインサート成型によって一体に埋め込まれることにより、バンド本体１０との境界面が相互に融合されている。すなわち、バンド本体１０と補強部１１とは、硬度が異なっていても、同じ材料であることにより、バンド本体１０と補強部１１との境界面が確実に融合される。このため、バンド本体１０と補強部１１とは、プライマーなどの下地処理や接着剤などを用いずに、密着強度が確保されるように形成されている。 As shown in FIG. 4, the reinforcing portion 11 is integrally embedded in the end portion 10a of the band main body 10 by insert molding in a state where the tip side is exposed from the end portion 10a of the band main body 10, so that the reinforcing portion 11 is integrally embedded with the band main body 10. Boundary surfaces are fused together. That is, even if the band main body 10 and the reinforcing portion 11 have different hardnesses, since they are made of the same material, the boundary surface between the band main body 10 and the reinforcing portion 11 is surely fused. Therefore, the band main body 10 and the reinforcing portion 11 are formed so as to secure the adhesion strength without using a base treatment such as a primer or an adhesive.

この場合、バンド本体１０の端部１０ａは、図５および図６に示すように、補強部１１の食込み側の肉厚が厚く、補強部１１の露出側に向かうに従って肉厚が次第に薄くなるように形成されている。すなわち、バンド本体１０の端部１０ａは、補強部１１の両側の各側部１３における上側の肉厚が腕時計ケース１側に位置する先端側に向けて次第に薄く形成されている。 In this case, as shown in FIGS. 5 and 6, the end portion 10a of the band main body 10 has a thick wall thickness on the biting side of the reinforcing portion 11, and the wall thickness gradually decreases toward the exposed side of the reinforcing portion 11. Is formed in. That is, the end portion 10a of the band main body 10 is formed so that the thickness of the upper side of each side portion 13 on both sides of the reinforcing portion 11 is gradually reduced toward the tip end side located on the wristwatch case 1 side.

すなわち、先端側に位置するバンド本体１０の端部１０ａの肉厚は、図５および図６に示すように、インサート成型が可能な最小限の厚さで薄く形成されている。つまり、バンド本体１０の片側半分の厚さ（表面側の半分の厚さ）よりも薄く形成されている。この場合、バンド本体１０の端部１０ａは、先端側の肉厚が薄くても、バンド本体１０と補強部１１との境界面が融合されていることにより、補強部１１から剥離しないように形成されている。 That is, as shown in FIGS. 5 and 6, the wall thickness of the end portion 10a of the band body 10 located on the distal end side is formed to be thin with the minimum thickness that allows insert molding. That is, it is formed thinner than the thickness of one half of the band body 10 (half the thickness of the surface side). In this case, the end portion 10a of the band main body 10 is formed so as not to be peeled off from the reinforcing portion 11 because the boundary surface between the band main body 10 and the reinforcing portion 11 is fused even if the wall thickness on the tip side is thin. Has been done.

また、バンド本体１０の端部１０ａは、補強部１１の回転止め部１５の下側の肉厚が腕時計ケース１側に位置する先端側に向けて次第に薄く形成されている。すなわち、先端側に位置するバンド本体１０の端部１０ａの肉厚も、インサート成型が可能な最小限の厚さで薄く形成されている。 Further, the end portion 10a of the band main body 10 is formed so that the thickness of the lower side of the rotation stop portion 15 of the reinforcing portion 11 gradually becomes thinner toward the tip end side located on the wristwatch case 1 side. That is, the wall thickness of the end portion 10a of the band body 10 located on the tip end side is also formed to be thin with the minimum thickness that allows insert molding.

つまり、バンド本体１０の端部１０ａは、バンド本体１０の片側半分の厚さ（表面側の半分の厚さ）よりも薄く形成されている。この場合にも、バンド本体１０の端部１０ａは、先端側の肉厚が薄くても、バンド本体１０と補強部１１との境界面が融合されていることにより、補強部１１から剥離しないように形成されている。 That is, the end portion 10a of the band body 10 is formed to be thinner than the thickness of one half of the band body 10 (half the thickness of the surface side). Also in this case, the end portion 10a of the band main body 10 does not peel off from the reinforcing portion 11 because the boundary surface between the band main body 10 and the reinforcing portion 11 is fused even if the wall thickness on the tip side is thin. Is formed in.

次に、この腕時計のバンド２の作用について説明する。
バンド２を製作する場合には、予め、補強部１１を成型する。このときには、補強部１１をフッ素樹脂で成型する場合には、JIS-A硬度が９０〜９５°のフッ素樹脂によって成型する。また、バンド本体１０を成型する場合には、インサート成型によって補強部１１をバンド本体１０の端部１０ａに埋め込む。 Next, the operation of the band 2 of this wristwatch will be described.
When the band 2 is manufactured, the reinforcing portion 11 is molded in advance. At this time, when the reinforcing portion 11 is molded with a fluororesin, it is molded with a fluororesin having a JIS-A hardness of 90 to 95 °. When the band body 10 is molded, the reinforcing portion 11 is embedded in the end portion 10a of the band body 10 by insert molding.

このときには、バンド本体１０を補強部１１の硬度よりも低いフッ素樹脂、つまりJIS-A硬度が７０〜７５°のフッ素樹脂によって成型する。このため、バンド本体１０の端部１０ａに埋め込まれた補強部１１は、バンド本体１０よりも硬度が高いので、バンド本体よりも強度が高くなり、この強度の高い補強部１１によってバンド本体１０の端部１０ａの強度が補強される。 At this time, the band body 10 is molded with a fluororesin having a hardness lower than that of the reinforcing portion 11, that is, a fluororesin having a JIS-A hardness of 70 to 75 °. Therefore, the reinforcing portion 11 embedded in the end portion 10a of the band main body 10 has a higher hardness than the band main body 10, so that the strength is higher than that of the band main body. The strength of the end portion 10a is reinforced.

これにより、補強部１１がバンド本体１０の端部１０ａに一体に埋め込まれる。このときには、バンド本体１０と補強部１１とは、硬度が異なっていても、同じ材料であることにより、バンド本体１０と補強部１１との境界面が確実にかつ強固に融合される。このため、バンド本体１０と補強部１１とは、プライマーなどの下地処理や接着剤などを用いずに、密着強度が確保されて、確実にかつ強固に一体化される。 As a result, the reinforcing portion 11 is integrally embedded in the end portion 10a of the band main body 10. At this time, since the band main body 10 and the reinforcing portion 11 are made of the same material even if the hardness is different, the boundary surface between the band main body 10 and the reinforcing portion 11 is surely and firmly fused. Therefore, the band main body 10 and the reinforcing portion 11 are surely and firmly integrated with each other while ensuring the adhesion strength without using a base treatment such as a primer or an adhesive.

この場合、バンド本体１０の端部１０ａは、補強部１１の食込み側の肉厚が厚く、補強部１１の露出側に向かうに従って肉厚が次第に薄くなるように形成される。すなわち、バンド本体１０の端部１０ａは、補強部１１の両側の各側部１３における上側の肉厚が腕時計ケース１側に位置する先端側に向けて次第に薄く形成されている。 In this case, the end portion 10a of the band main body 10 is formed so that the wall thickness on the biting side of the reinforcing portion 11 is thick and the wall thickness is gradually reduced toward the exposed side of the reinforcing portion 11. That is, the end portion 10a of the band main body 10 is formed so that the thickness of the upper side of each side portion 13 on both sides of the reinforcing portion 11 is gradually reduced toward the tip end side located on the wristwatch case 1 side.

この場合には、先端側に位置するバンド本体１０の端部１０ａの肉厚がインサート成型可能な最小限の厚さで薄く形成される。このように肉厚が薄く形成されても、補強部１１に対する密着強度が確保されているので、バンド本体１０の端部１０ａにおける肉厚の薄い箇所が補強部１１から剥離することがない。 In this case, the wall thickness of the end portion 10a of the band body 10 located on the tip end side is formed to be thin with the minimum thickness that can be insert-molded. Even if the wall thickness is formed thin in this way, the adhesion strength to the reinforcing portion 11 is ensured, so that the thin portion of the end portion 10a of the band main body 10 does not peel off from the reinforcing portion 11.

また、バンド本体１０の端部１０ａは、補強部１１の回転止め部１５の下側の肉厚が腕時計ケース１側に位置する先端側に向けて次第に薄く形成されている。この場合にも、先端側に位置するバンド本体１０の端部１０ａの肉厚がインサート成型可能な最小限の厚さで薄く形成されている。このように肉厚が薄く形成されても、補強部１１に対する密着強度が確保されているので、バンド本体１０の端部１０ａにおける肉厚の薄い箇所が補強部１１から剥離することがない。 Further, the end portion 10a of the band main body 10 is formed so that the thickness of the lower side of the rotation stop portion 15 of the reinforcing portion 11 gradually becomes thinner toward the tip end side located on the wristwatch case 1 side. Also in this case, the wall thickness of the end portion 10a of the band body 10 located on the tip end side is formed to be thin with the minimum thickness that can be insert-molded. Even if the wall thickness is formed thin in this way, the adhesion strength to the reinforcing portion 11 is ensured, so that the thin portion of the end portion 10a of the band main body 10 does not peel off from the reinforcing portion 11.

このように形成されたバンド２を腕時計ケース１のバンド取付部３に取り付ける場合には、まず、バンド本体１０の端部１０ａに埋め込まれた補強部１１の取付凹部１２に腕時計ケース１のバンド取付部３の取付凸部８を配置する。このときには、バンド本体１０の端部１０ａの両側に設けられた各挿入孔１０ｂ、および補強部１１の両側の各側部１３に設けられた一対の連結孔１４を取付凸部８の取付孔８ａに同一軸上に対応させる。 When the band 2 thus formed is attached to the band attachment portion 3 of the wristwatch case 1, first, the band attachment of the wristwatch case 1 is performed in the attachment recess 12 of the reinforcing portion 11 embedded in the end portion 10a of the band main body 10. The mounting convex portion 8 of the portion 3 is arranged. At this time, the insertion holes 10b provided on both sides of the end portion 10a of the band main body 10 and the pair of connecting holes 14 provided on the side portions 13 on both sides of the reinforcing portion 11 are provided with the mounting holes 8a of the mounting convex portion 8. Corresponds to the same axis.

この状態で、バンド本体１０の端部１０ａの一方の挿入孔１０ｂから補強部１１の一方の側部１３の連結孔１４を通して、連結部材９の第１ねじ部１６の軸部１６ｂを取付凸部８の取付孔８ａに挿入させる。また、バンド本体１０の端部１０ａの他方の挿入孔１０ｂから補強部１１の他方の側部１３の連結孔１４を通して、連結部材９の第２ねじ部１７のねじ部１７ｂを取付凸部８の取付孔８ａに挿入させる。 In this state, the shaft portion 16b of the first screw portion 16 of the connecting member 9 is attached through the connecting hole 14 of the one side portion 13 of the reinforcing portion 11 from one insertion hole 10b of the end portion 10a of the band main body 10. It is inserted into the mounting hole 8a of 8. Further, the threaded portion 17b of the second threaded portion 17 of the connecting member 9 is attached to the convex portion 8 through the connecting hole 14 of the other side portion 13 of the reinforcing portion 11 from the other insertion hole 10b of the end portion 10a of the band body 10. It is inserted into the mounting hole 8a.

そして、第１ねじ部１６のねじ孔１６ｃに第２ねじ部１７のねじ部１７ｂを螺合させて締め付ける。すると、第１ねじ部１６の頭部１６ａが一方の側部１３における連結孔１４の大径孔部１４ａに挿入され、第２ねじ部１７の頭部１７ａが他方の側部１３における連結孔１４の大径孔部１４ａに挿入される。 Then, the screw portion 17b of the second screw portion 17 is screwed into the screw hole 16c of the first screw portion 16 and tightened. Then, the head portion 16a of the first screw portion 16 is inserted into the large-diameter hole portion 14a of the connecting hole 14 on one side portion 13, and the head portion 17a of the second screw portion 17 is inserted into the connecting hole 14 on the other side portion 13. It is inserted into the large-diameter hole portion 14a of the above.

これにより、補強部１１の両側の各側部１３が、第１ねじ部１６の頭部１６ａと第２ねじ部１７の頭部１７ａとによって、バンド取付部３の取付凸部８に押し当てられて取付凸部８を挟み付ける。このため、バンド本体１０の端部１０ａの補強部１１が腕時計ケース１のバンド取付部３に取り付けられる。 As a result, the side portions 13 on both sides of the reinforcing portion 11 are pressed against the mounting convex portion 8 of the band mounting portion 3 by the head portion 16a of the first screw portion 16 and the head portion 17a of the second screw portion 17. The mounting convex portion 8 is sandwiched between the two. Therefore, the reinforcing portion 11 of the end portion 10a of the band main body 10 is attached to the band mounting portion 3 of the wristwatch case 1.

このように、腕時計ケース１のバンド取付部３にバンド２が取り付けられた際には、バンド本体１０の端部１０ａとこの端部１０ａに埋め込まれた補強部１１とは、連結部材９を中心に上下方向に回転する。このときには、補強部１１の下面に突出して設けられた回転止め部１５が腕時計ケース１の裏蓋６に接離可能に当接して、バンド本体１０の端部１０ａの回転が規制される。 In this way, when the band 2 is attached to the band attachment portion 3 of the wristwatch case 1, the end portion 10a of the band body 10 and the reinforcing portion 11 embedded in the end portion 10a are centered on the connecting member 9. Rotate up and down. At this time, the rotation stopper 15 projecting from the lower surface of the reinforcing portion 11 comes into contact with the back cover 6 of the wristwatch case 1 so as to be detachable, and the rotation of the end portion 10a of the band body 10 is restricted.

このように、この腕時計のバンド２によれば、弾力を有する合成樹脂製のバンド本体１０と、このバンド本体１０と同じ合成樹脂で、かつ硬度がバンド本体１０の硬度よりも高い補強部１１と、を備え、この補強部１１がバンド本体１０の端部１０ａに埋め込まれ、バンド本体１０と補強部１１との境界面が融合されていることにより、別部品を用いずに、バンド本体と補強部とを確実にかつ強固に一体化することができる。 As described above, according to the band 2 of this wristwatch, the band body 10 made of elastic synthetic resin and the reinforcing portion 11 having the same synthetic resin as the band body 10 and having a hardness higher than the hardness of the band body 10 , And this reinforcing portion 11 is embedded in the end portion 10a of the band main body 10, and the boundary surface between the band main body 10 and the reinforcing portion 11 is fused, so that the band main body and the reinforcing portion 11 are reinforced without using separate parts. The parts can be reliably and firmly integrated.

すなわち、この腕時計のバンド２では、補強部１１の硬度がバンド本体１０の硬度よりも高いので、補強部１１の強度をバンド本体１０よりも高めることができる。このため、補強部１１の先端側をバンド本体１０の端部１０ａから露出させた状態で、バンド本体１０の端部１０ａに補強部１１をインサート成型によって一体に埋め込むことにより、バンド本体１０の端部１０ａを補強部１１によって強度を補強することができる。 That is, in the band 2 of this wristwatch, the hardness of the reinforcing portion 11 is higher than the hardness of the band main body 10, so that the strength of the reinforcing portion 11 can be increased as compared with the band main body 10. Therefore, with the tip end side of the reinforcing portion 11 exposed from the end portion 10a of the band main body 10, the reinforcing portion 11 is integrally embedded in the end portion 10a of the band main body 10 by insert molding, whereby the end of the band main body 10 is formed. The strength of the portion 10a can be reinforced by the reinforcing portion 11.

この場合、バンド本体１０は、フッ素樹脂、ウレタン樹脂、シリコーン樹脂などの弾力を有する合成樹脂、例えばJIS-A硬度が７０〜７５°のフッ素樹脂によって形成され、補強部１１は、バンド本体１０と同じ合成樹脂で、かつ硬度がバンド本体１０の硬度よりも高い材料、例えばJIS-A硬度が９０〜９５°のフッ素樹脂で形成されていることにより、バンド本体１０の端部１０ａを補強部１１によって確実に補強することができる。 In this case, the band body 10 is formed of an elastic synthetic resin such as a fluororesin, a urethane resin, or a silicone resin, for example, a fluororesin having a JIS-A hardness of 70 to 75 °, and the reinforcing portion 11 is formed with the band body 10. By forming the same synthetic resin and a material having a hardness higher than that of the band body 10, for example, a fluororesin having a JIS-A hardness of 90 to 95 °, the end portion 10a of the band body 10 is reinforced by the reinforcing portion 11. Can be reliably reinforced by.

また、バンド本体１０と補強部１１とは、硬度が異なっていても、同じ材料であるので、バンド本体１０の端部１０ａに補強部１１をインサート成型によって一体に埋め込むことにより、バンド本体１０と補強部１１との境界面を確実にかつ良好に融合させることができる。このため、プライマーなどの下地処理や接着剤などを用いずに、バンド本体１０と補強部１１との密着強度を高めることができる。 Further, since the band main body 10 and the reinforcing portion 11 are made of the same material even if they have different hardness, the reinforcing portion 11 is integrally embedded in the end portion 10a of the band main body 10 by insert molding to form the band main body 10 and the reinforcing portion 11. The boundary surface with the reinforcing portion 11 can be reliably and satisfactorily fused. Therefore, it is possible to increase the adhesion strength between the band body 10 and the reinforcing portion 11 without using a base treatment such as a primer or an adhesive.

また、この腕時計のバンド２では、補強部１１とバンド本体１０との境界面におけるバンド本体１０の肉厚がインサート成型可能な最小限の厚さで薄く形成されていることにより、デザイン性を高めることができる。この場合、バンド本体１０の端部１０ａの肉厚を薄く形成しても、補強部１１に対する密着強度が確保されているので、バンド本体１０の端部１０ａにおける肉厚の薄い箇所が補強部１１から剥離することがない。このため、バンド本体１０の端部１０ａの強度を補強部１１によって高めることができる。 Further, in the band 2 of this wristwatch, the wall thickness of the band body 10 at the boundary surface between the reinforcing portion 11 and the band body 10 is formed as thin as the minimum thickness that can be insert-molded, thereby enhancing the design. be able to. In this case, even if the wall thickness of the end portion 10a of the band main body 10 is thinly formed, the adhesion strength to the reinforcing portion 11 is ensured. Therefore, the thin portion of the end portion 10a of the band main body 10 is the reinforcing portion 11. Does not peel off from. Therefore, the strength of the end portion 10a of the band main body 10 can be increased by the reinforcing portion 11.

また、この腕時計のバンド２では、バンド本体１０の長手方向と直交する幅方向における補強部１１の中間部に、被取付部材である腕時計ケース１の取付凸部８が挿入して取り付けられる取付凹部１２が設けられていることにより、バンド本体１０を腕時計ケース１に取り付ける際に、補強部１１の取付凹部１２に腕時計ケース１の取付凸部８を配置させることができ、これによりバンド本体１０の端部１０ａに埋め込まれた補強部１１によってバンド本体１０を腕時計ケース１に確実にかつ強固に取り付けることができる。 Further, in the band 2 of this wristwatch, the mounting concave portion 8 of the wristwatch case 1 to be mounted is inserted and mounted in the intermediate portion of the reinforcing portion 11 in the width direction orthogonal to the longitudinal direction of the band body 10. Since the band 12 is provided, when the band body 10 is attached to the wristwatch case 1, the mounting convex portion 8 of the wristwatch case 1 can be arranged in the mounting recess 12 of the reinforcing portion 11, whereby the band body 10 of the band body 10 can be arranged. The band body 10 can be securely and firmly attached to the wristwatch case 1 by the reinforcing portion 11 embedded in the end portion 10a.

すなわち、この腕時計のバンド２では、補強部１１の取付凹部１２に腕時計ケース１の取付凸部８を配置させた状態で、補強部１１の取付凹部１２の両側に位置する各側部１３と腕時計ケース１の取付凸部８とを連結部材９によって簡単にかつ確実に連結することができるので、連結部材９によってバンド本体１０が破損することなく、バンド本体１０を腕時計ケース１に確実にかつ良好に取り付けることができる。 That is, in the band 2 of this wristwatch, each side portion 13 and the wristwatch located on both sides of the mounting recess 12 of the reinforcing portion 11 in a state where the mounting convex portion 8 of the wristwatch case 1 is arranged in the mounting recess 12 of the reinforcing portion 11. Since the mounting convex portion 8 of the case 1 can be easily and surely connected by the connecting member 9, the band main body 10 is surely and goodly connected to the wristwatch case 1 without damaging the band main body 10 by the connecting member 9. Can be attached to.

この場合、腕時計ケース１の取付凸部８には取付孔８ａが設けられ、補強部１１の取付凹部１２の両側に位置する各側部１３には一対の連結孔１４が設けられ、バンド本体１０の端部１０ａの両側には各挿入孔１０ｂが設けられているので、これらバンド本体１０の端部１０ａの各挿入孔１０ｂ、補強部１１の一対の連結孔１４、および取付凸部８の取付孔８ａに連結部材９を挿入させることにより、バンド本体１０を腕時計ケース１に確実にかつ良好に取り付けることができる。 In this case, the mounting convex portion 8 of the wristwatch case 1 is provided with a mounting hole 8a, and each side portion 13 located on both sides of the mounting recess 12 of the reinforcing portion 11 is provided with a pair of connecting holes 14, and the band main body 10 is provided. Since each insertion hole 10b is provided on both sides of the end portion 10a of the band body 10, each insertion hole 10b of the end portion 10a of the band main body 10, a pair of connecting holes 14 of the reinforcing portion 11, and the mounting convex portion 8 are mounted. By inserting the connecting member 9 into the hole 8a, the band body 10 can be securely and satisfactorily attached to the wristwatch case 1.

すなわち、連結部材９は、第１ねじ部１６と第２ねじ部１７とを備え、第１ねじ部１６が頭部１６ａとねじ孔１６ｃが設けられた軸部１６ｂとを備え、第２ねじ部１７は頭部１７ａとねじ部１７ｂとを備えていることにより、第１ねじ部１６と第２ねじ部１７とをバンド本体１０の端部１０ａの各挿入孔１０ｂ、補強部１１の一対の連結孔１４、および取付凸部８の取付孔８ａに連結部材９を挿入させることにより、バンド本体１０を腕時計ケース１に確実にかつ良好に取り付けることができる。 That is, the connecting member 9 includes a first screw portion 16 and a second screw portion 17, and the first screw portion 16 includes a head portion 16a and a shaft portion 16b provided with a screw hole 16c, and the second screw portion is provided. Since the 17 has a head portion 17a and a threaded portion 17b, the first threaded portion 16 and the second threaded portion 17 are connected to each insertion hole 10b of the end portion 10a of the band body 10 and a pair of reinforcing portions 11. By inserting the connecting member 9 into the hole 14 and the mounting hole 8a of the mounting convex portion 8, the band body 10 can be securely and satisfactorily mounted on the wristwatch case 1.

この場合、連結部材９は、バンド本体１０の端部１０ａの一方の挿入孔１０ｂから補強部１１の一方の側部１３の連結孔１４を通して、第１ねじ部１６の軸部１６ｂを取付凸部８の取付孔８ａに挿入させると共に、バンド本体１０の端部１０ａの他方の挿入孔１０ｂから補強部１１の他方の側部１３の連結孔１４を通して、第２ねじ部１７のねじ部１７ｂを取付凸部８の取付孔８ａに挿入させることにより、第１ねじ部１６のねじ孔１６ｃに第２ねじ部１７のねじ部１７ｂを螺合させて締め付けることができる。 In this case, the connecting member 9 attaches the shaft portion 16b of the first screw portion 16 through the connecting hole 14 of one side portion 13 of the reinforcing portion 11 from one insertion hole 10b of the end portion 10a of the band main body 10. The threaded portion 17b of the second threaded portion 17 is mounted through the connecting hole 14 of the other side portion 13 of the reinforcing portion 11 from the other insertion hole 10b of the end portion 10a of the band body 10 while being inserted into the mounting hole 8a of the band main body 10. By inserting it into the mounting hole 8a of the convex portion 8, the screw portion 17b of the second screw portion 17 can be screwed into the screw hole 16c of the first screw portion 16 and tightened.

このため、この連結部材９は、第１ねじ部１６のねじ孔１６ｃに第２ねじ部１７のねじ部１７ｂを螺合させて締め付けることにより、第１ねじ部１６の頭部１６ａと第２ねじ部１７の頭部１７ａとによって補強部１１の両側の各側部１３をバンド取付部３の取付凸部８に押し当てて、補強部１１の両側の各側部１３でバンド取付部３の取付凸部８を挟み付けることができる。 Therefore, the connecting member 9 is tightened by screwing the screw portion 17b of the second screw portion 17 into the screw hole 16c of the first screw portion 16 to tighten the head 16a and the second screw of the first screw portion 16. Each side portion 13 on both sides of the reinforcing portion 11 is pressed against the mounting convex portion 8 of the band mounting portion 3 by the head portion 17a of the portion 17, and the band mounting portion 3 is mounted on each side portion 13 on both sides of the reinforcing portion 11.

これにより、連結部材９は、バンド本体１０の端部１０ａの補強部１１を腕時計ケース１のバンド取付部３に確実にかつ強固に取り付けることができる。第１ねじ部１６の頭部１６ａと第２ねじ部１７の頭部１７ａのように、頭部を備えたねじであってもバンド本体１０の端部１０ａの肉厚を薄く形成でき、バンド本体１０の端部１０ａの補強部１１を腕時計ケース１のバンド取付部３に確実にかつ強固に取り付けることができる。 As a result, the connecting member 9 can securely and firmly attach the reinforcing portion 11 of the end portion 10a of the band main body 10 to the band mounting portion 3 of the wristwatch case 1. Even if the screw has a head like the head portion 16a of the first screw portion 16 and the head portion 17a of the second screw portion 17, the wall thickness of the end portion 10a of the band body 10 can be thinly formed, and the band body can be formed thinly. The reinforcing portion 11 of the end portion 10a of 10 can be securely and firmly attached to the band mounting portion 3 of the wristwatch case 1.

さらに、この腕時計のバンド２では、補強部１１が腕時計ケース１に対して接離可能に当接する回転止め部１５を備えていることにより、腕時計ケース１に連結部材９によってバンド本体１０が取り付けられた状態で、連結部材９を中心にバンド本体１０の端部１０ａが回転しても、回転止め部１５によってバンド本体１０の端部１０ａの回転を規制することができる。 Further, in the band 2 of this wristwatch, the reinforcing portion 11 is provided with a rotation stopper 15 that comes into contact with the wristwatch case 1 so as to be in contact with the wristwatch case 1. Even if the end portion 10a of the band main body 10 rotates around the connecting member 9 in this state, the rotation of the end portion 10a of the band main body 10 can be restricted by the rotation stop portion 15.

すなわち、この腕時計のバンド２では、腕時計ケース１のバンド取付部３にバンド２が取り付けられた状態で、バンド本体１０の端部１０ａとこの端部１０ａに埋め込まれた補強部１１とが連結部材９を中心に上下方向に回転しても、補強部１１の下面に突出して設けられた回転止め部１５を腕時計ケース１の裏蓋６に接離可能に当接させることができるので、バンド本体１０の端部１０ａの回転を確実にかつ良好に規制することができる。 That is, in the band 2 of this wristwatch, the end portion 10a of the band main body 10 and the reinforcing portion 11 embedded in the end portion 10a are connected members in a state where the band 2 is attached to the band attachment portion 3 of the wristwatch case 1. Even if the wristwatch case 9 is rotated in the vertical direction, the rotation stopper 15 projecting from the lower surface of the reinforcing portion 11 can be brought into contact with the back cover 6 of the wristwatch case 1 so as to be in contact with the band main body. The rotation of the end portion 10a of the 10 can be reliably and satisfactorily regulated.

なお、上述した実施形態では、バンド本体１０を同じ色の材料で形成した場合について述べたが、この発明は、これに限らず、例えば図８に示す変形例のように、バンド本体１０の厚み方向において、表面側の半分Ｂ１と裏面側の半分Ｂ２とで材料の色が異なるように形成しても良い。 In the above-described embodiment, the case where the band body 10 is formed of the same color material has been described, but the present invention is not limited to this, and the thickness of the band body 10 is not limited to this, for example, as in the modified example shown in FIG. In the direction, the half B1 on the front surface side and the half B2 on the back surface side may be formed so that the colors of the materials are different.

また、表面側の半分Ｂ１と裏面側の半分Ｂ２とで材料の硬度を変えても良い。この場合、表面側の半分Ｂ１の硬度は、裏面側の半分Ｂ２の硬度よりも高く、補強部１１の硬度が一番高く形成すれば良い。つまり、硬度の高い順に、補強部１１、表面側の半分Ｂ１、裏面側の半分Ｂ２となれば良い。また、バンド本体１０と補強部１１とで材料の色が異なるように形成しても良い。このようにすれば、バンド２のカラー化を図ることができ、デザイン性を高めることができる。 Further, the hardness of the material may be changed between the half B1 on the front surface side and the half B2 on the back surface side. In this case, the hardness of the half B1 on the front surface side may be higher than the hardness of the half B2 on the back surface side, and the hardness of the reinforcing portion 11 may be formed to be the highest. That is, the reinforcing portion 11, the half B1 on the front surface side, and the half B2 on the back surface side may be formed in descending order of hardness. Further, the band body 10 and the reinforcing portion 11 may be formed so that the colors of the materials are different. By doing so, it is possible to colorize the band 2 and enhance the design.

また、上述した実施形態では、連結部材９が第１ねじ部１６と第２ねじ部１７とを備えた構造である場合について述べたが、この発明は、これに限らず、例えば金属ピンやばね棒などであっても良い。 Further, in the above-described embodiment, the case where the connecting member 9 has a structure including the first screw portion 16 and the second screw portion 17 has been described, but the present invention is not limited to this, and for example, a metal pin or a spring. It may be a stick or the like.

さらに、上述した実施形態では、腕時計に適用した場合について述べたが、この発明は、必ずしも腕時計である必要はなく、例えば腕に装着して使用する腕装着装置、または看板やバッグ、あるいは衣服などのバンドにも適用することができる。 Further, in the above-described embodiment, the case where it is applied to a wristwatch has been described, but the present invention does not necessarily have to be a wristwatch, for example, an arm-worn device used by being worn on an arm, a signboard, a bag, clothes, or the like. It can also be applied to the band of.
