  That is, as shown in FIGS. 2 to 5, the recess 10 a is formed in an elongated rectangular shape in a direction orthogonal to the longitudinal direction of the band body 7. Thus, the reinforcing member 8 is formed so that a thick portion is not generated in the reinforcing member 8 due to the recess 10a that has digged into the reinforcing member 8 when it is molded by an injection mold (not shown). Accordingly, sink marks are not generated during the injection molding of the reinforcing member 8.

  2 to 5, when the reinforcing member 8 is insert-molded into the one end portion 7a of the band body 7, a part of the molding die is inserted. The position of the reinforcing member 8 relative to the one end 7a of the band body 7 is restricted by restricting the position of the reinforcing member 8 in the mold.

  Further, as shown in FIGS. 2 to 5, the connection attachment portion 12 of the reinforcing member 8 has a substantially semicircular cross-sectional shape, and extends along the direction perpendicular to the longitudinal direction of the band body 7 at the lower portion of the body portion 10. Is provided. The coupling attachment portion 12 is provided with a coupling insertion hole 12 a through which the spring bar 11 is inserted along a direction orthogonal to the longitudinal direction of the band body 7.

And a pair of pin portions 11b that are inserted into both sides of the pipe 11a so as to be able to appear and retract, and a spring member 11c that is disposed in the pipe 11a and biases the pair of pin portions 11b in a pushing direction.

  As a result, the spring bar 11 is connected to the reinforcing member 8 with the band insertion hole 7d provided in the lower side portion 7c of the both side portions of the end portion 7a of the band body 7 as shown in FIGS. In a state of being inserted into the connection insertion hole 12a of the attachment portion 12, the pair of pin portions 11b protrudes laterally from the lower side of the upper portion 7b on both side portions of the band body 7, and the protruding pair of pin portions 11b The band 5 is configured to be attached to the band attachment portion 6 of the watch case 1 by being inserted into the attachment holes 6 b provided on the opposing surfaces of the pair of attachment projections 6 a of the watch case 1.

  On the other hand, as shown in FIGS. 3 and 5, the cutout portion 13 that is a biting portion of the reinforcing member 8 is provided in an intermediate portion in a direction perpendicular to the longitudinal direction of the band body 7 in the connection mounting portion 12 of the reinforcing member 8. It has been. That is, the notch 13 is formed with a length of about 1/3 of the length of the main body 10 of the reinforcing member 8 in the direction perpendicular to the longitudinal direction of the band main body 7.

  For this reason, as shown in FIGS. 2, 3, and 5, the notch 13 is formed so as to divide the connecting attachment portion 12 of the reinforcing member 8 into two and bite into the lower surface of the main body portion 10. . The notch 13 is configured to firmly fix the reinforcing member 8 to the band main body 7 when the reinforcing member 8 is insert-molded into the band main body 7 and part 7e of the band main body 7 bites into the band main body 7. ing.

  In this case, a part 7e of the band body 7 that has bitten into the notch 13 of the reinforcing member 8 is connected to a biting insertion hole 7f into which the pipe 11a of the spring bar 11 is inserted, as shown in FIGS. The mounting portion 12 is provided on the same axis as the connecting insertion hole 12a. The biting insertion hole 7f is configured to be formed at the same time when the band body 7 is molded.

  As shown in FIGS. 2 to 5, when the band body 7 is attached to the band attachment portion 6 of the watch case 1, the reinforcing member 8 rotates the band body 7 around the spring bar 11. A rotation restricting portion 14 for restricting is provided. The rotation restricting portion 14 is provided on the exposed surface exposed from the end surface of the one end portion 7 a of the band main body 7 in the main body portion 10 of the reinforcing member 8. That is, the rotation restricting portion 14 includes a first contact portion 14 a that contacts the outer surface of the watch case 1 and a second contact portion 14 b that contacts the lower surface of the watch case 1.

  1 to 4, the band 5 is attached by the spring bar 11 so that the one end portion 7 a of the band body 7 is disposed between the pair of attachment projections 6 a in the band attachment portion 6 of the watch case 1. When the first contact portion 14a of the rotation restricting portion 14 is in contact with the outer peripheral surface of the watch case 1, and the second contact portion 14b of the rotation restricting portion 14 is in contact with the lower surface of the watch case 1, A gap is not formed between the end surface of the one end portion 7 a of the band body 7 and the outer surface of the watch case 1.

Next, a case where such a wristwatch band 5 is manufactured will be described.
In this case, the reinforcing member 8 is manufactured in advance. At this time, when the reinforcing member 8 is, for example, metal, it is formed by cutting. When the reinforcing member 8 is a hard synthetic resin, the reinforcing member 8 is molded with an injection mold for the reinforcing member 8.

  That is, when the reinforcing member 8 is a hard synthetic resin, the recess 10 a is formed by biting into the inside of the reinforcing member 8 on the exposed surface of the reinforcing member 8 exposed from the end surface of the one end portion 7 a of the band body 7. Thus, when the reinforcing member 8 is molded with an injection molding die (not shown), the reinforcing member 8 can be formed so as not to sink due to the concave portion 10a that has digged into the reinforcing member 8.

  As a result, as shown in FIG. 5, the reinforcing member 8 is integrally formed with the main body portion 10, the coupling attachment portion 12, and the notch portion 13. At this time, the concave portion 10a, the first contact portion 14a of the rotation restricting portion 14, and the second contact portion 14b of the rotation restricting portion 14 are formed in the main body portion 10, and the connection insertion hole 12a is formed in the connection attaching portion 12. Is done.

  When the reinforcing member 8 is insert-molded into the one end portion 7 a of the band body 7, a slide pin (not shown) having the same outer diameter as the pipe 11 a of the spring bar 11 is inserted into the connecting insertion hole 12 a of the connecting attachment portion 12 of the reinforcing member 8. And the reinforcing member 8 is disposed in a mold (not shown) for molding the band main body 7 in this state. At this time, a part of the mold is inserted into the recess 10 a provided in the main body 10 of the reinforcing member 8. Thereby, the position of the reinforcing member 8 is accurately and accurately regulated in the mold.

  In this state, when a soft synthetic resin is filled in the mold for molding the band body 7 and cured, the band body 7 in which the reinforcing member 8 is embedded is formed. At this time, the soft synthetic resin filled in the mold is cut into the biting portion of the reinforcing member 8 in a state of covering almost the entire reinforcing member 8 except for one surface of the main body portion 10 of the reinforcing member 8. In addition to filling the notch 13, both sides of the reinforcing member 8 are also filled.

  When the mold for molding the band body 7 is released and the band body 7 is taken out, the band 5 in which the reinforcing member 8 is embedded in the one end portion 7a of the band body 7 is obtained. The band 5 includes a first contact portion 14a and a second contact portion of the rotation restricting portion 14 provided on the body portion 10 from one end portion 7a of the band main body 7 to one surface of the main body portion 10 of the reinforcing member 8. The reinforcing member 8 is firmly fixed in the one end portion 7a of the band main body 7 in a state where 14b is exposed.

  In other words, the band 5 is formed by a part 7e of the band body 7 biting into the notch 13 which is a biting part of the reinforcing member 8, so that the reinforcing member 8 is firmly inside the one end 7a of the band body 7. Fixed to. Further, the band 5 is formed as long as possible in the range of the length between both side portions of the one end portion 7a of the band body 7 in the length of the reinforcing member 8 in the direction orthogonal to the longitudinal direction of the band body 7. Therefore, the reinforcing member 8 is firmly fixed in the one end portion 7 a of the band body 7.

  In addition, the band 5 is formed by inserting a part of the mold into the concave portion 10a of the reinforcing member 8 at the time of insert molding and accurately positioning the reinforcing member 8 in the insert molding mold. The position of the reinforcing member 8 with respect to the one end 7a of 7 is regulated with high accuracy. As a result, both side portions of the one end portion 7 a of the band body 7 are formed with a uniform thickness, and each end surface of both side portions of the one end portion 7 a of the band body 7 corresponding to the outer surface of the wristwatch case 1 is It is formed in the same plane as the exposed surface of the reinforcing member 8 exposed from the one end portion 7a.

  In this case, when the mold for molding the band body 7 is released, the thick upper part 7b and the thin lower part 7c are formed on both sides of the one end part 7a of the band body 7. It is formed. For this reason, the band 5 has one side of the main body 10 of the reinforcing member 8 exposed to the outside from the end surface of the one end 7 a of the band main body 7, and both sides of the band main body 7 formed on both sides of the reinforcing member 8. The reinforcing member 8 is firmly fixed in the one end portion 7a of the band body 7 even if the lower side portion 7c is formed thin.

  Further, when the mold for molding the band body 7 is released, the slide pin is removed. Then, band insertion holes 7d are provided on the same axis as the connection insertion holes 12a of the connection attachment portion 12 of the reinforcing member 8 on the lower side portions 7c of both side portions of the one end portion 7a of the band main body 7, and are connected to each other. A biting insertion hole 7f is provided in a part 7e of the band main body 7 that bites into the notch 13 positioned between the mounting portions 12 so as to correspond to the connecting insertion hole 12a of the connecting mounting portion 12 of the reinforcing member 8 on the same axis. It is done.

Next, a case where such a band 5 is attached to the watch case 1 will be described.
In this case, first, the spring bar 11 is attached to the one end 7 a of the band body 7. At this time, the pipe 11 a of the spring bar 11 is inserted into the band insertion hole 7 d provided in the lower side portion 7 c on both sides of the one end portion 7 a of the band body 7 and the connection insertion provided in the connection attachment portion 12 of the reinforcing member 8. It inserts on the same axis | shaft in the hole 12a and the bite insertion hole 7f provided in the part 7e of the band main body 7 cut into the notch part 13 located between the connection attachment parts 12. FIG.

  Then, the pair of pin portions 11b of the spring bar 11 is pushed out and protrudes from the lower side of the upper side portions 7b on both sides of the one end portion 7a of the band body 7 by the spring force of the spring member 11c in the pipe 11a. In this state, when the band body 7 is attached to the band attachment portion 6 of the watch case 1, the pair of pin portions 11b are pushed toward the inside of the pipe 11a against the spring force of the spring member 11c, Each tip portion of the pin portion 11 b is disposed below the upper portion 7 b on both sides of the one end portion 7 a of the band body 7.

  In this state, the one end portion 7a of the band body 7 is disposed between the pair of attachment projections 6a of the band attachment portion 6, and the tip ends of the pair of pin portions 11b are respectively opposed to the opposing surfaces of the pair of attachment projections 6a. It corresponds to each provided mounting hole 6b. At this time, each of the pair of pin portions 11b passes through the gap S provided between the thin lower portion 7c provided on both sides of the one end portion 7a of the band body 7 and the pair of mounting projections 6a. While visually recognizing the tip part, it is made to correspond to each mounting hole 6b on the opposing surface of the pair of mounting projections 6a.

  Then, a pair of pin part 11b is extruded by the spring force of the spring member 11c, and each front-end | tip part of this pair of pushed pin part 11b inserts in each attachment hole 6b of a pair of attachment projection part 6a, respectively. As a result, the one end 7 a of the band body 7 is attached to the pair of attachment protrusions 6 a by the spring bar 11 together with the reinforcing member 8. As a result, the band 5 is attached to the band attaching portion 6 of the watch case 1.

  In this state, the upper side portions 7b on both sides of the one end portion 7a of the band main body 7 are elastically held between both side portions of the reinforcing member 8 and the pair of mounting projections 6a of the band mounting portion 6. Thereby, the band 5 is attached to the band attachment portion of the watch case 1 so that no gap is formed between the upper side portions 7b on both sides of the one end portion 7a of the band body 7 and the pair of attachment projections 6a of the band attachment portion 6. 6 is attached.

  At this time, the rotation restricting portion 14, which is the exposed surface of the reinforcing member 8 exposed from the end surface of the one end portion 7 a of the band main body 7, is positioned on the same plane as the end surfaces of both side portions of the one end portion 7 a of the band main body 7. By being formed, the rotation restricting portion 14 of the reinforcing member 8 faces and contacts the outer surface of the wristwatch case 1 together with the end surfaces of both ends of the one end portion 7 a of the band body 7. Thereby, the rotation of the band 5 around the spring bar 11 is restricted.

  That is, in the rotation restricting portion 14, the first abutting portion 14 a abuts on the outer peripheral surface of the watch case 1 positioned between the pair of attaching projections 6 a of the band attaching portion 6, and the second abutting portion 14 b is in contact with the watch case 1. It contacts the lower surface located on the lower outer periphery. For this reason, the band 5 is prevented from rotating around the spring bar 11, and the band 5 is formed so that no gap is formed between the outer surface of the watch case 1 and the end surface of the one end portion 7 a of the band body 7. It is attached to the band attaching part 6 of the watch case 1.

  In this state, since the reinforcing member 8 is embedded in the one end portion 7a of the band body 7, the band body 7 is attached to the band attaching portion 6 of the watch case 1 by the reinforcing member 8, so that the band 5 is attached to the watch case 1. Can be attached firmly. In this case, the reinforcing member 8 is formed as long as possible in the range of the length between both side portions of the one end portion 7a of the band body 7 in the direction orthogonal to the longitudinal direction of the band body 7. This also firmly attaches the band 5 to the watch case 1.

  For this reason, even if the band main body 7 is pulled with respect to the wristwatch case 1 or is rotated around the spring bar 11, the deformation of the one end portion 7a of the band main body 7 can be reliably suppressed. Even if it is made of a material, there is no gap between the end surface of the one end portion 7a of the band body 7 and the outer surface of the watch case 1, and the upper side portions 7b on both sides of the one end portion 7a of the band body 7 There is no gap between the pair of attachment projections 6a in the band attachment portion 6 of the watch case 1. Thereby, a sense of unity between the wristwatch case 1 and the band 5 is obtained.

  Further, when the band 5 is removed from the band attaching portion 6 of the wristwatch case 1, the thin lower side portion 7c provided on both sides of the one end portion 7a of the band body 7 and the pair of attaching projections 6a are provided. Since a gap S is provided between them, a tool is provided in the gap S between the lower side portion 7c and the pair of mounting projections 6a while visually confirming the tip ends of the pair of pin portions 11b of the spring bar 11 through the gap S. And the pair of pin portions 11b are separated from the respective mounting holes 6b of the pair of mounting projections 6a against the spring force of the spring member 11c, whereby the band 5 is removed from the band mounting portion 6 of the watch case 1. It can be easily removed.

  As described above, according to the wristband 5 of the wristwatch, the hard material reinforcing member 8 embedded in the one end portion 7a of the soft material band main body 7 by insert molding is connected to the one end portion 7a of the band main body 7 from the end surface. A body portion 10 that is embedded with the portion exposed, a connection attachment portion 12 that is provided in the body portion 10 along a direction orthogonal to the longitudinal direction of the band body 7 and to which the spring bar 11 is attached, and at the time of insert molding Since the part 7e of the band main body 7 is provided with the notch 13 that bites into the main body 10, the strength of the reinforcing member 8 attached to the band main body 7 is increased and the deformation of the band main body 7 with respect to the reinforcing member 8 is improved. Can be reliably suppressed.

  That is, in this wristband 5, a part 7 e of the band main body 7 can be bitten into the notch 13 which is a biting part of the reinforcing member 8, so that the strength of attaching the reinforcing member 8 to the band main body 7 is increased. In addition, the deformation of the band body 7 with respect to the reinforcing member 8 can be reliably suppressed. Thereby, even if the band main body 7 is formed of a soft material, it is possible to prevent a gap from being formed between the end surface of the one end portion 7a of the band main body 7 and the outer surface of the watch case 1, so that the watch case 1 And a sense of unity with the band 5 can be obtained.

  In this case, the notch 13 which is a biting portion of the reinforcing member 8 is located at an intermediate portion in a direction orthogonal to the longitudinal direction of the band main body 7 in the connection mounting portion 12 of the reinforcing member 8 and bites into the lower surface of the main body portion 10. Thus, when the reinforcing member 8 is insert-molded into the band main body 7, a part 7 e of the band main body 7 can be surely bitten into the cutout portion 13, thereby the reinforcing member 8. Can be securely and firmly fixed to the band body 7.

  That is, the cutout portion 13 is formed to have a length about 1/3 of the length of the main body portion 10 of the reinforcing member 8 in the direction orthogonal to the longitudinal direction of the band main body 7.
