In the present embodiment, the first band 3 a is arranged at the 12 o'clock side in the wristwatch 1, and the second band 3 b is arranged at the 6 o'clock side in the wristwatch 1.
The band 3 (the first band 3a and the second band 3b) is formed of various resin materials such as polyurethane, for example. In addition, the material which forms the band 3 is not limited to what was illustrated. For example, it may be formed of a metal material such as stainless steel or titanium, ceramics, or a combination thereof or a combination of these with various resin materials.

As shown in FIGS. 1 and 2, etc., the second band 3b disposed on the wristwatch 1 at the 6 o'clock side has the side end of the wristwatch case 2 attached to the wristwatch case 2 as described above. The second band 3 b is integrated with the outer peripheral portion 24 constituting the outer periphery, and extends outward from the side portion of the watch case 2. In the present embodiment, the second band 3b is formed to have an angle so as to be inclined about 30 degrees toward the back side (downward in FIG. 8) with respect to the wristwatch case 2. As a result, the second band 3b extends obliquely downward on the back side of the wristwatch case 2. The angle of the second band 3b with respect to the watch case 2 is not limited to that exemplified here. The second band 3b may have a larger angle with respect to the watch case 2, or the second band 3b may be provided substantially parallel to the bottom surface (case back surface) of the watch case 2.
The second band 3b is not limited to one in which the end portion on the side attached to the watch case 2 is integrated with the outer peripheral portion 24 constituting the outer periphery of the side portion of the watch case 2. The configuration for attaching the second band 3b to the watch case 2 is provided, for example, by providing a band attaching portion for attaching the second band 3b at the end of the watch case 2 at 6 o'clock, and attaching the second band 3b. A case attachment portion corresponding to the band attachment portion is provided at the end, and the band attachment portion and the case attachment portion are fitted and connected, and a rod-like member such as a spring bar is inserted through the connection portion. For example, the second band 3b may be attached to the watch case 2.

The first band 3 a arranged on the wristwatch 1 at the 12 o'clock side is attached to the case back surface of the wristwatch case 2. As described above, only the first band 3a of the pair of bands 3 is attached to the back surface of the case 2 so that the thickness of the watch case 2 is 12:00 of the wristwatch 1 than the thickness of the wristwatch 1 at 6 o'clock. The thickness on the side is thicker by the thickness of the first band 3a.
The first band 3 a includes a band main body 31 and a case attachment portion 32 that is integrally provided with the band main body 31 at an end portion of the band main body 31 on the attachment side to the watch case 2. A buckle 310 including a cap 311 and a tack bar 312 is attached to the band main body 31 at the end opposite to the side attached to the watch case 2.
The first band 3a is preferably provided with fixed leather and free leather into which the tip (sword tip) of the second band 3b is inserted. In FIGS. Is omitted.

In the present embodiment, the first band 3a is attached to the watch case 2 by screwing the case attachment portion 32 to the case back surface of the watch case 2 (the back cover 23 in this embodiment).
Specifically, a through hole 321 through which the screw 25 is inserted is formed at a position corresponding to the screw hole 232 of the back cover 23 in the case mounting portion 32, and the first band 3 a is connected to the case mounting portion 32. The screw 25 is inserted into the through hole 321 and the screw hole 232 of the back cover 23 from below (lower in FIG. 9), and the screw 25 is screwed into the screw hole 232 to be fixed to the case back surface of the watch case 2.

Further, the first band 3 a can be rotated around the screw 25 with respect to the watch case 2 by loosening the screw 25.
As shown in FIG. 10, the first band 3a and the second band 3b are loosened by loosening the screws 25 and rotating the first band 3a by 180 degrees (reversing the mounting direction of the first band 3a). It will be in the state where it arranged so that may overlap.
The screw 25 may be fixed with some play, and the first band 3a may be rotated without loosening the screw 25.

  In the present embodiment, the case attachment portion 32 is formed with an angle so as to be inclined about 30 degrees toward the back side of the band 3 with respect to the band main body 31. Thus, when the case attaching portion 32 is attached to the case back surface (that is, the back cover 23) of the watch case 2, the band main body 31 extends obliquely downward on the back surface side of the watch case 2. In addition, the angle with respect to the band main body 31 of the case attaching part 32 is not limited to what was illustrated here. The case attaching part 32 may have a larger angle with respect to the band main body 31, or the case attaching part 32 may be provided without being inclined with respect to the band main body 31.

Further, in the present embodiment, the case mounting portion 32 of the first band 3a covers at least a part of the case back surface (back cover 23 in the present embodiment) of the wristwatch case 2 and at the 6 o'clock side (that is, the wristwatch 1). The case attachment portion 32 is an inclined portion that inclines so as to increase in thickness from the side of the attachment side end of the watch case 2 to the watch case 2 toward the 12 o'clock side of the watch 1 (that is, the band main body 31 side).
Thus, the case mounting portion 32 is provided with an inclination so that the thickness gradually increases from the 6 o'clock side of the wrist watch 1 to the 12 o'clock side of the wrist watch 1, so that the wrist watch 1 is attached to the arm. At this time, the band 3 becomes familiar with the arm, and the fit is increased, and the rotation (displacement) of the band 3 to the 12 o'clock side can be more reliably suppressed.
The range of the case back surface of the watch case 2 (in this embodiment, the back cover 23) covered by the case mounting portion 32 is not particularly limited. For example, the case mounting portion 32 covers the entire case back surface of the watch case 2. Also good. Even in this case, by providing the case mounting portion 32 with a slope that gradually increases in thickness from the 6 o'clock side of the wristwatch 1 toward the 12 o'clock side of the wristwatch 1, the thickness of the watch case 2 on the 12 o'clock side is 6 o'clock. The thickness of the band 3 can be made larger than that of the side, and the rotation (displacement) of the band 3 toward the 12 o'clock side can be suppressed.

Next, the effect | action of the band attachment structure in this embodiment is demonstrated.
In the present embodiment, when attaching the first band 3 a disposed on the 12 o'clock side of the wristwatch 1, the back cover 23 is placed so that the band fixing portion 231 of the back cover 23 is received in the recess 71 of the timepiece module 7. After the arrangement, the case attachment portion 32 of the first band 3a is overlapped on the case back surface of the watch case 2 (the back cover 23 in this embodiment) so that the thin tip end side comes to the 6 o'clock side of the watch 1. Match. The position is adjusted so that the through hole 321 of the case mounting portion 32 is aligned with the screw hole 232 of the back cover 23, the screw 25 is inserted into the through hole 321 and the screw hole 232 from below, and the screw 25 is screwed into the screw hole 232. Let As a result, the first band 3 a is attached to the watch case 2.
On the other hand, the second band 3b arranged on the wristwatch 1 at the 6 o'clock side has an end on the side attached to the watch case 2 integrated with the outer periphery of the side of the watch case 2, and the second band 3b It extends outward from the side of the watch case 2.
In this way, only the first band 3 a arranged on the 12 o'clock side of the wristwatch 1 is attached to the back cover 23, which is the case back surface of the wristwatch case 2, so that the wristwatch case 2 can be The left side in FIGS. 3, 8, and 9 is thicker than the 6 o'clock side in the wristwatch 1 (the right side in FIGS. 3, 8, and 9) by the thickness of the first band 3a. Thus, when the wristwatch 1 is worn on the wrist, the band 3 is difficult to rotate to the 12 o'clock side of the wristwatch 1 and the wristwatch 1 is prevented from shifting outward.
In the present embodiment, the first band 3 a can be rotated in the in-plane direction on the case back surface of the watch case 2 by loosening the screws 25. If the mounting direction of the first band 3a is reversed by 180 degrees, the first band 3a and the second band 3b can be aligned in the same direction, and the buckle 310 can be easily carried by being hooked on a key holder or the like. It becomes possible. In addition, when the first band 3a and the second band 3b are aligned in the same direction and overlap each other, the wristwatch 1 can be easily stored in a pocket or the like.

As described above, according to the present embodiment, the first band 3 a disposed on the 12 o'clock side of the wristwatch 1 is attached to the back cover 23 that is the case back surface of the wristwatch case 2. Thereby, the wristwatch case 2 has a 12 o'clock side (the left side in FIGS. 3, 8, and 9) on the wristwatch 1 rather than a 6 o'clock side (the right side in FIGS. 3, 8, and 9) on the wristwatch 1. The thickness is increased by the thickness of the first band 3a. The wrist to which the wristwatch 1 is attached has a slightly elliptical shape in cross section. While the wristwatch 1 is being worn, the wristband 1 is easily shifted to the outside due to the rotation of the band 3 at the 12 o'clock side of the wristwatch 1. Difficult to maintain. In this regard, the watch case 2 is made thicker at the 12 o'clock side of the wristwatch 1 than at the 6 o'clock side of the wristwatch 1, thereby preventing the band 3 from rotating to the 12 o'clock side of the wristwatch 1. The Thereby, it can prevent that the wristwatch 1 shifts outside while wearing the wristwatch 1.
The first band 3a is rotatably attached to the back cover 23 that is the back surface of the case. Therefore, the first band 3a and the second band 3b can be aligned in the same direction by reversing the mounting direction of the first band 3a by 180 degrees. Thereby, it is possible to use the wristwatch 1 such that the buckle 310 is hooked on a key holder or the like and carried, and the use of the wristwatch 1 is expanded. In addition, when the first band 3a and the second band 3b are aligned in the same direction and overlap, the wristwatch 1 can be put in a pocket or the like without being bulky even if the band 3 is made of a material that is somewhat hard and difficult to deform. Since it can be stored, it is convenient when carrying the wristwatch 1.
In the present embodiment, the first band 3 a is attached to the back cover 23, which is the back surface of the case, with a screw 25. Thereby, the 1st band 3a can be attached to the case back surface of the wristwatch case 2 with a simple configuration.
Further, the first band 3a covers at least a part of the case back surface (back cover 23 in the present embodiment) of the watch case 2 and gradually moves from the 6 o'clock side of the watch 1 to the 12 o'clock side of the watch 1. A case mounting portion 32 that is inclined so as to increase in thickness is integrally formed. Since the case attaching portion 32 is an inclined portion having such an inclination, when the wristwatch 1 is attached to the arm, the band 3 becomes familiar with the arm and the fit feeling is increased. Further, since the thickness of the wristwatch case 2 at the 12 o'clock side of the wristwatch 1 is increased by an amount corresponding to the inclination, the rotation (displacement) of the band 3 toward the 12 o'clock side of the wristwatch 1 is more reliably prevented, and the wristwatch 1 is It is possible to prevent shifting.

In this embodiment, a band fixing portion 231 having a thicker thickness than the others is provided in a part of the back cover 23 which is the case back surface of the watch case 2, and a screw hole 232 for screwing the screw 25 into the band fixing portion 231. However, the configuration for screwing the screws 25 is not limited to this.
For example, the back cover 23 may be formed in a plate shape, and a screw hole for screwing the screw 25 into the watch module 7 housed inside the watch case 2 may be formed. In this case, the back cover 23 is provided with a through hole at a position corresponding to the screw hole of the timepiece module 7.

[Second Embodiment]
Next, a second embodiment of the band mounting structure according to the present invention will be described with reference to FIG. The present embodiment is different from the first embodiment only in the configuration for attaching the case mounting portion of the first band to the case back surface of the watch case, and therefore, in the following, particularly different from the first embodiment. The point will be described.

FIG. 11 is a schematic cross-sectional view of a wristwatch to which the band mounting structure of this embodiment is applied.
As shown in FIG. 11, the watch case 2 of the present embodiment includes a flat-plate-like back cover 23 attached to the lower surface (the lower surface in FIG. 11) of the case frame 21.

A ball joint member 26 is fixed on the lower surface of the back cover 23 (the lower surface in FIG. 11) at the 12 o'clock side of the wristwatch and substantially at the center in the width direction of the timepiece. The ball joint member 26 includes a leg portion 261 that is fixed to the lower surface (the lower surface in FIG. 11) of the back cover 23, and a substantially spherical joint portion 262 that is formed at the lower end of the leg portion 261.
The method of fixing the ball joint member 26 is not particularly limited. For example, the ball joint member 26 may be attached to the back cover 23 by bonding or welding the leg portion 261, or the leg portion 261 may be screwed to the back cover 23 with a screw or the like. Moreover, you may use what integrally molded the back cover 23 and the ball joint member 26. FIG. Further, the ball joint member 26 only needs to be provided on the back surface of the watch case 2 and is not limited to the one fixed to the back cover 23. For example, the watch module 2 may be fixed to the watch module 7 or the like inside the watch case 2 with screws or the like.

An engagement hole 331 is formed at a position corresponding to the ball joint member 26 in the case mounting portion 33 of the first band 3c.
The engagement hole 331 penetrates in the thickness direction of the case attachment portion 33 (vertical direction in FIG. 11), and a substantially spherical joint holding portion 331a into which the spherical joint portion 262 of the ball joint member 26 is fitted, and this joint The insertion portion 331b is formed at the upper portion of the holding portion 331a, and the insertion portion 331c is formed at the lower portion of the joint holding portion 331a. The insertion portion 331b has a tapered shape that gradually spreads from the joint holding portion 331a toward the upper portion of the case mounting portion 33, and the diameter of the insertion portion 331b on the joint holding portion 331a side is smaller than the diameter of the joint portion 262. The diameter of the opening side of the upper part of the case attaching part 33 of the insertion part 331b is larger than the diameter of the joint part 262. The insertion portion 331c has a tapered shape that gradually spreads from the joint holding portion 331a toward the lower portion of the case mounting portion 33. The diameter of the insertion portion 331c on the joint holding portion 331a side is larger than the diameter of the joint portion 262. It is getting smaller.
In the present embodiment, the case attachment portion 33 of the first band 3c is formed of a flexible material such as resin, and the insertion portion 331b is formed by pushing the joint portion 262 of the ball joint member 26 from the insertion portion 331b. Will be expanded. Thereby, the joint part 262 can be fitted in the joint holding part 331a.

  In addition, since the other structure is the same as that of 1st Embodiment, the same code | symbol is attached | subjected to the same member and the description is abbreviate | omitted.

Next, the effect | action of the band attachment structure in this embodiment is demonstrated.
In the present embodiment, when attaching the first band 3c arranged at 12 o'clock in the wristwatch 1, the case attachment portion 33 of the first band 3c is attached to the case back surface (back cover 23) of the wristwatch case 2. The joint portion 262 of the ball joint member 26 provided on the back cover 23 is pushed into the engagement hole 331 from the insertion portion 331b of the case attachment portion 33 while being superimposed on the 12 o'clock side of the wristwatch. The first band 3 c is attached to the watch case 2 by fitting the joint part 262 into the joint holding part 331 a.
As described above, only the first band 3c arranged on the 12 o'clock side of the wristwatch is attached to the back cover 23 which is the case back surface of the wristwatch case 2, so that the wristwatch case 2 is attached to the 12 o'clock side of the wristwatch (see FIG. 11 on the left side is thicker than the 6 o'clock side on the wristwatch (the right side in FIG. 11) by the thickness of the first band 3c. Thereby, when the wristwatch is mounted on the wrist, the band 3 is difficult to rotate to the 12 o'clock side of the wristwatch, and the wristwatch is prevented from shifting to the outside.
In the present embodiment, since the first band 3c can be rotated in the in-plane direction on the case back surface of the watch case 2, if the first band 3c is rotated approximately 180 degrees, the second band 3b It is also possible to align the directions and superimpose. Further, since the case mounting portion 33 of the first band 3c can freely rotate around the spherical joint portion 262, the first band 3d fits well to the arm when the wristwatch is attached to the arm. Good wearability.

  Since other points are the same as those in the first embodiment, description thereof is omitted.

As described above, according to the present embodiment, the following effects can be obtained in addition to the same effects as those of the first embodiment.
That is, in the present embodiment, the first band 3 c is attached to the watch case 2 by the ball joint member 26.
For this reason, the 1st band 3c can be rotated more smoothly and the user can enjoy changing the direction of the 1st band 3c freely. In addition, if the first band 3c is rotated approximately 180 degrees so as to be superposed on the second band 3b, it is convenient even if the wristwatch is carried in a pocket or the like.
In addition, since the ball joint member 26 is used for attaching the first band 3c as described above, the case attaching portion 33 of the first band 3c is not only rotated in the in-plane direction on the case back surface of the watch case 2. The spherical joint portion 262 can be freely rotated. For this reason, when the wristwatch is worn on the arm, the first band 3d fits well on the arm, and the wearability is improved.

In the present embodiment, the case where the engagement hole 331 for engaging the ball joint member 26 is configured by the joint holding portion 331a and the insertion portion 331b and the insertion portion 331c formed above and below the joint holding portion 331a is exemplified. The shape and configuration of the engagement hole 331 are not limited to those illustrated here.
For example, when the ball joint member 26 is pushed in from above the case attachment portion 33 and engaged with the engagement hole 331, the insertion hole 331c may not be provided without the engagement hole 331 being a through hole. In this case, the joint portion 262 of the ball joint member 26 cannot be seen from the outside, which is preferable in terms of appearance.

Further, the method of engaging the joint portion 262 of the ball joint member 26 with the engagement hole 331 of the first band 3c is not limited to the one exemplified here.
For example, when the ball joint member 26 is a separate member from the back cover 23 and is fixed to the back cover 23 by screwing or the like, the ball joint member 26 is positioned below the case mounting portion 33 (FIG. 11). The joint portion 262 may be engaged with the engagement hole 331 by being pushed into the engagement hole 331 from below) and then fixed to the back cover 23 by screwing or the like.

That is, in the present embodiment, the first band 3d is attached to the watch case 2 by the damper joint member 27 having elasticity.
For this reason, the 1st band 3d can be rotated more smoothly and the user can enjoy changing the direction of the 1st band 3d freely. Further, if the first band 3d is rotated by approximately 180 degrees so as to be superposed on the second band 3b, it is convenient even if the wristwatch is carried in a pocket or the like.
Further, since the damper joint member 27 is flexed freely, the case mounting portion 34 of the first band 3d can be freely rotated around the joint portion 272 as well as rotating in the in-plane direction on the case back surface of the watch case 2. When the wristwatch is worn on the arm, the first band 3d fits well on the arm and wearability is improved.

In this embodiment, the example in which the joint portion 272 of the damper joint member 27 is pushed into the engagement hole 341 of the first band 3d from above and the joint portion 272 is engaged with the joint holding portion 341b has been described. The configurations of the joint portion 272 and the engagement hole 341 of the joint member 27 are not limited to those illustrated.
For example, the damper joint member 27 is a separate member from the back cover 23 and is fixed to the back cover 23 by screwing or the like, and the engagement hole 341 of the first band 3d has a diameter larger than that of the joint portion 272. It is good also as a through-hole which consists of the large joint holding part 341b and the insertion part 341a whose diameter is smaller than the joint part 272, and penetrates in the thickness direction (up-down direction in FIG. 12) of the case attachment part 34. In this case, for example, the leg portion 271 of the damper joint member 27 is inserted from below the case attachment portion 34 (downward in FIG. 12) to engage the joint portion 272 with the engagement hole 341, and then the damper joint member. 27 leg portions 271 are fixed to the back cover 23 by screws or the like.
