[0008] [First embodiment] The first embodiment will be described below with reference to the drawings. As shown in Fig. 1, wristwatch 100 as a timepiece comprises exterior case 101, first band 1 and second band 2. Cans 102 are provided integrally at the 6 o'clock and 12 o'clock positions of exterior case 101. First band 1 is connected to can 102 at the 6 o'clock position using an attachment pin, and second band 2 is connected to can 102 at the 12 o'clock position using an attachment pin.

[0009] The first band 1 and the second band 2 are assembled by connecting a plurality of links 3, each of which is made up of a center link 3A and an outer link 3B, as shown in Fig. 2. An end link 30A is provided at the open end of the first band 1, and an end link 30 is provided at the open end of the second band 2, as shown in Fig. 3. These end links 30, 30A are connected by a clasp 5, as shown in Figs. 2 to 5.

[0010] The clasp 5 is a three-fold clasp equipped with a folding member 9. Fig. 2 is a perspective view of the clasp 5 with the folding member 9 open, Fig. 3 is an exploded perspective view showing the clasp 5 and end link 30, and Fig. 4 is a partially exploded perspective view showing the back side of the cover 11 of the clasp. In each figure, the axis along the longitudinal direction of the first band 1 and the second band 2 is the X-axis, the axis along the width direction of the first band 1 and the second band 2 perpendicular to the X-axis is the Y-axis, and the axis perpendicular to the X-axis and the Y-axis is the Z-axis. On the X-axis, the direction from the clasp 5 toward the first band 1 is the X1 direction, and the direction from the clasp 5 toward the second band 2 is the X2 direction. On the Y-axis, the direction from the center of the width direction of the cover 11 toward the first side portion 131 side is the Y1 direction, and the direction toward the second side portion 132 side is the Y2 direction. On the Z-axis, the direction in which the first side portion 131 and the second side portion 132 extend from the bottom portion 12 of the cover 11 is the Z1 direction, and the opposite direction is the Z2 direction. Here, when the wristwatch 100 is worn on the user's arm, the Z1 direction is the exterior case 101 side in the clasp 5, so the Z1 direction may be expressed as upward and the Z2 direction as downward. In addition, in each component, the surface on the Z1 direction side may be expressed as the top surface, and the surface on the Z2 direction side may be expressed as the bottom surface.

[0011] As shown in FIGS. 2 to 4, the clasp 5 includes a bending member 9 and a clasp body 10. As shown in FIG. The bending member 9 is a typical bending member including a middle plate 91 and an outer plate 92 having a hook 94, and therefore a description thereof will be omitted.

[0012] [Configuration of clasp body] The clasp body 10 includes a cover 11 and a button unit 20, as shown in FIGS.

[0013] As shown in Figures 2 to 4, the cover 11 has a plate-shaped bottom portion 12 curved in an arc along the X1 and X2 directions, and a first side portion 131 and a second side portion 132 protruding in the Z1 direction from the outer edges of the bottom portion 12 in the Y1 and Y2 directions. The first side surface portion 131 and the second side surface portion 132 are formed with through holes 14 through which the first button 21 and the second button 22 of the button unit 20 are inserted. The first side portion 131 and the second side portion 132 are formed with a hole 15 for attaching a spring bar 93 to which the outer plate 92 is connected, and a hole 16 for attaching an end link 30 of the second band 2. In this embodiment, the first side portion 131 and the second side portion 132 are formed with two holes 16 spaced apart in the X-axis direction, and by attaching the end link 30 to one of the holes 16, the length of the second band 2 extending from the clasp body 10 can be adjusted in two stages.

[0014] The button unit 20 includes a first button 21, a second button 22, a case 23 that houses the first button 21 and the second button 22, and a coil spring (not shown) that biases the first button 21 and the second button 22 in a direction away from each other. The first button 21 and the second button 22 are biased in a direction that protrudes from the through hole 14 by the coil spring (not shown). The first button 21 and the second button 22 are formed with engagement pieces 21A and 22A that are L-shaped in plan view. The engagement piece 21A is disposed between the second button 22 and the engagement piece 22A, and the engagement piece 22A is disposed between the first button 21 and the engagement piece 21A. Therefore, the engagement pieces 21A and 22A are configured to approach each other when the first button 21 and the second button 22 are biased by the coil spring in a direction away from each other, and to be separated from each other when the first button 21 and the second button 22 are pressed. An elliptical opening 24 is formed in the center of the surface of case 23, and when folding member 9 is folded closed, hook 94 of middle plate 91 is inserted between engagement pieces 21A, 22A through opening 24, and the umbrella portion at the tip of hook 94 pushes engagement pieces 21A, 22A apart against the biasing force of the coil spring. When the umbrella portion overcomes engagement pieces 21A, 22A, the shaft portion of hook 94 is clamped by engagement pieces 21A, 22A due to the biasing force of the coil spring, and hook 94 is held by engagement pieces 21A, 22A. Furthermore, when the user presses the first button 21 and the second button 22, the engagement pieces 21A and 22A move away from each other, so that the hook 94 is disengaged and the folding member 9 can be opened.

[0015] [End link of second band] Next, the end link 30 of the second band 2 will be described with reference to FIG. The end link 30 is detachably attached to the cover 11 via a spring bar 40 with a lever, which serves as an engagement member. The end link 30 is formed by machining a solid metal material by cutting, etc. The end link 30 has a body 31 and a first arm 32 and a second arm 33 which extend in the X2 direction from both ends of the body 31 in the Y-axis direction. A through hole 34 penetrating in the Y-axis direction is formed in the body 31. A groove portion 35 opening on the upper surface of the first arm portion 32 is formed in the end portion of the body 31 on the first arm portion 32 side, and this groove portion 35 communicates with the through hole 34. A through hole 36 penetrating in the Y-axis direction is formed in the first arm 32 and the second arm 33. A center piece 3A of the link 3 is disposed between the first arm 32 and the second arm 33, and the first arm 32, the second arm 33 and the center piece 3A are connected by a pin 37 penetrating the through hole 36 and the center piece 3A.

[0016] The spring bar 40 includes a pipe portion 41, a first shaft member 42, a second shaft member 43, and a coil spring 44. The pipe portion 41 is formed in a cylindrical shape, and a long hole 411 is formed on one end side. The left and right ends of the pipe portion 41 have openings with smaller diameters than the middle portion. The first shaft member 42 includes a shaft portion 421 that is larger in diameter than the end opening of the pipe portion 41 and is disposed within the pipe portion 41, and a pin 422 that protrudes from the shaft portion 421, protrudes from the end opening of the pipe portion 41, and is inserted into the hole 16 of the first side surface portion 131. A lever-shaped operating portion 45 that protrudes from the long hole 411 is fixed to the shaft portion 421 of the first shaft member 42 by a screw or press fit. The second shaft member 43 includes a shaft portion 431 that has a diameter larger than the end opening of the pipe portion 41 and is disposed within the pipe portion 41, and a pin 432 that protrudes from the shaft portion 431, protrudes from the end opening of the pipe portion 41, and is inserted into a hole 16 of the second side portion 132. Each of the pins 422, 432 of the first shaft member 42 and the second shaft member 43 is an engagement portion that can engage with the hole 16 of the cover 11, and this is the same in each of the following embodiments. The coil spring 44 is disposed between the first shaft member 42 and the second shaft member 43 inside the pipe portion 41, and is set so that the pins 422, 432 of the first shaft member 42 and the second shaft member 43 protrude from both end openings of the pipe portion 41. At this time, the operating portion 45 is located at the end of the long hole 411 on the pin 422 side, and when the operating portion 45 is slid toward the second shaft member 43 side to compress the coil spring 44, the first shaft member 42 to which the operating portion 45 is fixed also moves toward the second shaft member 43 side, and the protruding dimension of the pin 422 from the pipe portion 41 becomes smaller.

[0017] 5, when the bending member 9 is folded and the clasp 5 is closed, the movement of the operating part 45 in the Y2 direction is restricted by the side surface 921 of the outer plate 92. In other words, the bending member 9 is a restricting part that restricts the operating part 45 from unintentionally moving in the Y2 direction and causing the pin 422 of the first shaft member 42 of the spring bar 40 to come out of the hole 16. 6, in a side view of the clasp 5 seen from the Y-axis direction, the length L1 from the central axis of the pin 422 of the first shaft member 42 engaged with the hole 16 of the cover 11 to the tip of the operating part 45 is less than or equal to the length L2 from the central axis of the pin 422 to the surface 922 of the folding member 9 in the folded state. The surface 922 of the folding member 9 is the surface in the Z1 direction, and is the surface that comes into contact with the user's wrist when the wristwatch 100 is worn. For this reason, when the clasp 5 and band are in use with the folding member 9 folded, the operating part 45 does not protrude beyond the folding member 9 and come into contact with the user's wrist.

[0018] 7, the maximum protruding dimension of the pins 422, 432 of the first shaft member 42 and the second shaft member 43, that is, the length L3 by which the pins 422, 432 protrude from the end of the pipe portion 41 when the first shaft member 42 and the second shaft member 43 are biased in directions away from each other by the coil spring 44, is set to be shorter than the thickness T1 of the first side surface portion 131 and the second side surface portion 132 in which the hole 16 is formed. This prevents the pins 422, 432 from protruding out of the first side surface portion 131 and the second side surface portion 132 from the hole 16, improving the design.

[0019] [How to adjust the band length] Next, a method for adjusting the band length will be described. When adjusting the band length, the clasp 5 is opened to move the outer plate 92 of the folding member 9 from the restricting position that restricts the movement of the operating part 45 to the non-restricting position that does not restrict the movement. Next, the operating part 45 is moved in the Y2 direction, that is, toward the second side surface portion 132, and the pin 422 is moved to the non-engagement position and removed from the hole 16 of the first side surface portion 131. Then, the end portion of the end link 30 on the operating part 45 side is moved in the Z1 direction (upward) relative to the first side surface portion 131, and the first shaft member 42 of the spring bar 40 is tilted to a position where it does not abut against the first side surface portion 131. This allows the spring bar 40 to move in the Y1 direction relative to the end link 30, so that the pin 432 can be removed from the hole 16 of the second side surface portion 132. Next, the end link 30 is moved in the X-axis direction, which is the longitudinal direction of the second band 2, relative to the cover 11, the pin 432 of the second shaft member 43 is inserted into another hole 16 formed in the cover 11, and while the first shaft member 42 is moved in the Y2 direction by the operation unit 45, the end of the end link 30 on the operation unit 45 side is moved in the Z2 direction, and the pin 422 is aligned with the position of the hole 16 on the first side surface portion 131 side and the operation unit 45 is released. Then, the first shaft member 42 is moved in the Y1 direction by the coil spring 44, and the pin 422 moves to the engagement position and is inserted into the hole 16. By the above operations, the hole 16 of the cover 11 with which the spring bar 40 of the end link 30 engages can be selected, so that the band length can be adjusted.

[0020] [Effects of the first embodiment] By operating the operating part 45 of the spring bar 40, which is an engagement member held by the end link 30, to move the pin 422 of the first shaft member 42 to the disengagement position and engage the pin 422 with a hole 16 selected from the multiple holes 16 formed in the cover 11, the engagement position between the cover 11 and the end link 30 can be changed to adjust the length of the band. Therefore, the user can easily adjust the band length by operating the operating part 45 and there is no need to use a dedicated adjustment tool, so the pin 422 of the first shaft member 42 can be easily attached and detached to and from the cover 11, and the band length adjustment operation can also be easily performed. This eliminates the need for a dedicated adjustment tool and reduces the number of parts, reducing the manufacturing costs of the band made up of the first band 1, second band 2, and clasp 5. Furthermore, the structure for adjusting the band length is simple, making it easy to manufacture the band.

[0021] When the clasp 5 is closed, such as when the wristwatch 100 is worn by the user, the movement of the folding member 9 restricts the movement of the operating part 45, thereby reliably preventing the operating part 45 from moving unintentionally in the Y2 direction and causing the pin 422 of the first shaft member 42 to come out of the hole 16. When the clasp 5 is closed, the operating part 45 does not protrude beyond the surface 922 of the folding member 9, so that the operating part 45 is prevented from hitting the user's wrist and impairing the wearing comfort. Since the protruding dimension L3 of the pins 422, 432 of the first shaft member 42 and the second shaft member 43 is less than the thickness T1 of the first side portion 131 and the second side portion 132, the pins 422, 432 can be prevented from protruding outside the cover 11, thereby improving the appearance of the cover 11.

[0022] [Second embodiment] 8, the band of the second embodiment is configured such that the length in the thickness direction (Z-axis direction) of the first side surface portion 131A of the cover 11A of the clasp body 10A is increased to hide the operating portion 45 in a side view. That is, the length L1 from the central axis of the pin 422 of the first shaft member 42 engaged with the hole 16 of the cover 11A to the tip of the operating portion 45 is equal to or less than the length L4 from the central axis of the pin 422 to the free end 1311 on the Z1 direction side, which is the thickness direction of the first side surface portion 131. The free end 1311 of the first side surface portion 131 means, of the two edges provided apart in the Z-axis direction, which is the thickness direction, of the first side surface portion 131, not the edge connected to the bottom surface portion 12 but the edge not connected to the bottom surface portion 12, and means the upper surface of the first side surface portion 131 facing the exterior case 101 side.

[0023] [Effects of the second embodiment] The band of the second embodiment can achieve the same effects as those of the first embodiment with the same configuration. Furthermore, the operating portion 45 is hidden by the cover 11A in a side view, which improves the appearance.

[0024] [Third embodiment] The band of the third embodiment differs from the first and second embodiments in that the groove of the end link 30B in which the operating part 45 is arranged is an elongated hole 35B, as shown in Fig. 9. For this reason, as shown in Fig. 10, the spring bar 40 without the operating part 45 attached is inserted into the through hole 34B of the end link 30B, and then the operating part 45 is fixed to the shaft part 421 of the first shaft member 42 via the elongated hole 35B. For example, the operating part 45 may be fixed by being pressed into the hole of the shaft part 421, or a male thread may be formed in the operating part 45 and screwed into a female thread formed in the shaft part 421.

[0025] [Effects of the third embodiment] The band of the third embodiment has the same configuration as the first and second embodiments and can achieve the same effects. Furthermore, since the operating part 45 is disposed in the long hole 35B with both ends closed, after the operating part 45 is attached to the first shaft member 42, the spring bar 40 will not come off from the end link 30B when the end link 30B is removed from the cover 11. Therefore, the end link 30B and the spring bar 40 can be integrated and can be easily handled.

[0026] [Fourth embodiment] 11 to 13, the band of the fourth embodiment differs from the first to third embodiments in that the end link 50 is composed of two members, a first link 51 and a second link 61. Note that the configurations of the clasp 5, first band 1, and second band 2 are the same as those of the first embodiment, so explanations and illustrations will be omitted. The first link 51 of the end link 50 is made of a metal material, and includes a first arm portion 52, a second arm portion 53, and a connecting portion 54, as shown in FIG. A first through hole 521, a first concave groove portion 522, a fixing hole 523, and a connecting hole 524 are formed in the first arm portion 52. The first through hole 521, the fixing hole 523, and the connecting hole 524 are each formed to penetrate the first arm portion 52 in the Y-axis direction. The first concave groove portion 522 opens in the upper surface of the first arm portion 52 and communicates with the first through hole 521.

[0027] The second arm portion 53 is formed with a second groove portion 531, a fixing hole 533, and a connecting hole 534. The second groove portion 531 is formed on an extension line of the first through hole 521 and the first groove portion 522 of the first arm portion 52, and is a groove that penetrates the second arm portion 53 in the Y-axis direction and also opens on the upper surface of the second arm portion 53. The bottom surface of the second groove portion 531 is formed in an arc shape like the first through hole 521. The fixing hole 533 is a through hole that passes through the second arm portion 53 in the Y-axis direction and is coaxial with the fixing hole 523. The connecting hole 534 is a through hole that passes through the second arm portion 53 in the Y-axis direction and is coaxial with the connecting hole 524.

[0028] The connecting portion 54 connects the first arm portion 52 and the second arm portion 53. Specifically, as shown in Fig. 12, the connecting portion 54 is formed in the middle between both ends in the X-axis direction of the first arm portion 52 and the second arm portion 53, on the upper surface side in the Z1 direction. A side surface of the connecting portion 54 on the X1 direction side is formed as an inclined surface 541.

[0029] The second link 61 of the end link 50 is made of a metal material, and has a through hole 611 , a recessed groove portion 612 , a fixing hole 613 , and a holding groove 615 . The through hole 611 is formed penetrating the second piece 61 in the Y-axis direction. The groove portion 612 is opened on the upper surface of the second piece 61 and communicates with the through hole 611. When the first piece 51 and the second piece 61 are assembled, the groove portion 612 is continuous with the first groove portion 522. The fixing hole 613 is formed penetrating the second piece 61 in the Y-axis direction. The holding groove 615 is a recessed groove that opens into the upper surface of the second piece 61, and is formed so that the connecting portion 54 can be disposed therein. The spring bar 40, which is an engagement member, is inserted into the through hole 611 of the second block 61. The structure of the spring bar 40 is the same as that of the first embodiment, so it is given the same reference numerals and description thereof will be omitted.

[0030] 13(A), with the spring bar 40 inserted into the through hole 611 of the second block 61, the first shaft member 42 side of the spring bar 40 is inserted into the first through hole 521 and the second shaft member 43 side is disposed in the second groove portion 531. The operating portion 45 is disposed in the first groove portion 522. Next, the first link 51 and the second link 61 are rotated relatively with the spring bar 40 as the rotation axis. At this time, since the inclined surface 541 is formed on the connecting portion 54, the connecting portion 54 can be placed in the holding groove 615. Then, the pin 55 is inserted through the fixing holes 523, 613, and 533, and the first link 51 and the second link 61 are connected and fixed. Furthermore, the center link 3A of the second band 2 is disposed between the first arm portion 52 and the second arm portion 53, and the end link 50 is connected to the center link 3A by inserting the pin 56 through the connecting holes 524, 534 and a through hole formed in the center link 3A.

[0031] As in the first embodiment, the end link 50 provided at the end of the second band 2 is connected to the cover 11 by inserting the pins 422, 432 of the first shaft member 42 and the second shaft member 43 into the holes 16 of the cover 11. As in the first embodiment, the length of the band can be adjusted by operating the operating part 45 to remove the pins 422, 432 from the holes 16 and inserting them into other holes 16.

[0032] [Effects of the fourth embodiment] According to the band of the fourth embodiment, the end link 50 is composed of two components, the first link 51 and the second link 61. Therefore, the spring bar 40, which is the engaging member with the operating portion 45 attached, can be positioned between the first link 51 and the second link 61 and assembled, thereby improving the ease of assembly of the end link 50.

[0033] Furthermore, since an inclined surface 541 is formed on the connecting portion 54, the first link 51 and the second link 61 can be assembled by rotating relatively with the spring bar 40 as the rotation axis, and further, the end link 50 can be easily assembled by inserting the pin 55 into the fixing holes 523, 613, 533. Furthermore, since the end link 50 is composed of separate components, the first link 51 and the second link 61, the first link 51 and the second link 61 can be made of different materials, such as metal, ceramic, or resin, allowing for a wider range of design variations.

[0034] [Fifth embodiment] As shown in Figs. 14 and 15, the band of the fifth embodiment differs from that of the fourth embodiment in that an end link 50B and a spring bar 40B serving as an engagement member are used. The end link 50B is configured to include a first link 51B and a second link 61B. The first link 51B is made of a metal material and includes a first arm portion 52B, a second arm portion 53B, and a connecting portion 54B. The first arm 52B is formed with a first groove 521B, a fixing hole 523B, and a connecting hole 524B. The first groove 521B is a groove that penetrates the first arm 52B in the Y-axis direction and is also open to the upper surface of the first arm 52B. The bottom surface of the first groove 521B is formed in an arc shape so as to rotatably support the pipe 41B of the spring bar 40B. The fixing hole 523B and the connecting hole 524B are each formed to penetrate the first arm portion 52B in the Y-axis direction.

[0035] The second arm portion 53B is formed with a second groove portion 531B, a fixing hole 533B, and a connecting hole 534B. The second groove portion 531B is a groove that penetrates the second arm portion 53B in the Y-axis direction, similar to the first groove portion 521B, and is also open to the upper surface of the second arm portion 53B. The bottom surface of the second groove portion 531B is formed in an arc shape, similar to the first groove portion 521B. The fixing hole 533B and the connecting hole 534B are each formed to penetrate the second arm portion 53B in the Y-axis direction.

[0036] Similar to the connecting portion 54 of the fourth embodiment, the connecting portion 54B connects the first arm portion 52B and the second arm portion 53B, and the side surface of the connecting portion 54B is formed as an inclined surface 541B similar to the inclined surface 541.

[0037] The second link 61B of the end link 50B is made of a metal material and has a recessed groove portion 611B, a fixing hole 613B, and a holding groove 615B. The groove portion 611B is formed penetrating the second piece 61B in the Y-axis direction and communicates with the holding groove 615B. That is, the groove portion 611B is open in the X2 direction. The bottom surface of the groove portion 611B on the X1 direction side is formed in an arc shape. The fixing hole 613B is formed penetrating the second piece 61B in the Y-axis direction. The holding groove 615B is a groove that opens to the upper surface of the second piece 61B and communicates with the groove portion 611B, and is formed so that the connecting portion 54B can be disposed therein.

[0038] A spring bar 40B, which is an engagement member, is inserted into the recessed groove 611B of the second link 61B. The spring bar 40B is similar to the spring bar 40 of the first embodiment, but differs in that operation portions 45B, 46B are provided on both ends. The spring bar 40B includes a pipe portion 41B, a first shaft member 42B, a second shaft member 43B, and a coil spring (not shown). The pipe portion 41B is formed in a cylindrical shape, and long holes 411B, 412B are formed at both ends in the longitudinal direction. The left and right ends of the pipe portion 41B have openings with smaller diameters than the middle portion. The first shaft member 42B has the same configuration as the first shaft member 42, and therefore a description thereof will be omitted. An operating portion 45B that protrudes from the long hole 411B is attached to the first shaft member 42B. The second shaft member 43B has a configuration similar to that of the first shaft member 42B, and an operating portion 46B that protrudes from the long hole 412B is attached to the second shaft member 43B. The operating portions 45B and 46B are the same members as the operating portion 45, and therefore a description thereof will be omitted. The coil spring is disposed between the first shaft member 42B and the second shaft member 43B in the pipe portion 41B, similarly to the spring bar 40 of the first embodiment. The operating portions 45B, 46B are located on the end sides of the long holes 411B, 412B. When the operating portions 45B, 46B are slid toward each other to compress the coil spring, the first shaft member 42B and the second shaft member 43B also move toward each other, and the pins 422, 432 of the first shaft member 42B and the second shaft member 43B can be removed from the holes 16.

[0039] Next, a method of assembling the end link 50B will be described. The pre-assembled spring bar 40B is attached to the recessed groove 611B of the second link 61B. That is, as shown in FIG. 15, the pipe portion 41B of the spring bar 40B is moved from the retaining groove 615B of the second link 61B to the recessed groove 611B and attached. Next, both ends of the spring bar 40B attached to the second link 61B are placed in the first groove portion 521B and the second groove portion 531B of the first link 51B. Then, the first link 51B and the second link 61B are rotated relatively around the spring bar 40B as the center of rotation, and the connecting portion 54B is placed in the holding groove 615B. Then, the pin 55B is inserted through the fixing holes 523B, 613B, and 533B, and the first link 51B and the second link 61B are connected and fixed. Furthermore, the center link 3A of the second band 2 is disposed between the first arm portion 52B and the second arm portion 53B, and the pin 56B is inserted through the connecting holes 524B, 534B and a through hole formed in the center link 3A to connect the end link 50B to the center link 3A.

[0040] The end link 50B provided at the end of the second band 2 is connected to the cover 11 by operating the operating parts 45B, 46B to insert the pins 422, 432 of the first shaft member 42B and the second shaft member 43B into the holes 16 of the cover 11. In addition, the length of the band can be adjusted by operating the operating parts 45B, 46B to remove the pins 422, 432 of the first shaft member 42B and the second shaft member 43B from the holes 16 and sliding the end link 50B in the X-axis direction to insert the pins 422, 432 into other holes 16.

[0041] [Effects of the Fifth Embodiment] According to the band of the fifth embodiment, the end link 50B is composed of two components, the first link 51B and the second link 61B, so that it is possible to achieve the same effects as the fourth embodiment and improve the ease of assembly of the end link 50B. Since an inclined surface 541B is formed on the connecting portion 54B, similarly to the fourth embodiment, the end link 50B can be easily assembled by rotating the first link 51B and the second link 61B relatively with the spring bar 40B as the rotation axis and inserting the pin 55B into the fixing holes 523B, 613B, 533B.

[0042] Since the spring bar 40B has operating portions 45B, 46B at both ends, both the first shaft member 42B and the second shaft member 43B can be moved by operating the operating portions 45B, 46B, and the spring bar 40B, i.e., the end link 50B, can be easily attached to and detached from the cover 11. The first piece 51B is formed with two grooves, a first groove 521B and a second groove 531B, and the second piece 61B is formed with a groove 611B that communicates with the retaining groove 615B, so that the spring bar 40B can be easily attached to the first piece 51B and the second piece 61B.

[0043] [Sixth embodiment] As shown in Figs. 16 and 17, the band of the sixth embodiment differs from the fifth embodiment in that an end link 50C and a spring bar 40C serving as an engagement member are used. The end link 50C is configured to include a first link 51C and a second link 61C. The first link 51C is made of a metal material and includes a first arm portion 52C, a second arm portion 53C, and a connecting portion 54C.

[0044] The first arm 52C and the second arm 53C are formed with grooves 521C, 531C that penetrate in the Y-axis direction and are also open to the upper surfaces of the first arm 52C and the second arm 53C. At this time, at the ends in the X1 direction of the first arm 52C and the second arm 53C, the walls 525C, 535C that partition the grooves 521C, 531C are cut out at both ends in the Y-axis direction. In addition, the first arm 52C and the second arm 53C are formed with a fixing hole through which a pin for connecting to the second link 61C is inserted and a connecting hole through which a pin for connecting to the middle link 3A is inserted, but since these are the same as in the fourth and fifth embodiments, their explanation will be omitted. The connecting portion 54C connects the first arm portion 52C and the second arm portion 53C, similar to the connecting portions 54 and 54B of the fourth and fifth embodiments, and the side surface of the connecting portion 54C is an inclined surface.

[0045] The second link 61C of the end link 50C has the same configuration as the second link 61B of the fifth embodiment, and therefore the description thereof will be omitted. The spring bar 40C, like the spring bar 40B of the fifth embodiment, is configured to include a pipe portion 41C, a first shaft member 42C, a second shaft member 43C, operation portions 45C and 46C, and a coil spring (not shown). The operation portions 45C and 46C are disposed in the elongated holes 411C and 412C of the pipe portion 41C.

[0046] The assembly method of the end link 50C and the method of attaching it to the second band 2 are the same as those in the fifth embodiment, and therefore the description will be omitted. The method of attaching and detaching the end link 50C to and from the cover 11 is also the same as those in the fifth embodiment. That is, in the first state in which the operation parts 45C and 46C of the end link 50C provided at the end of the second band 2 are oriented in the Z1 direction as shown in FIG. 16, the operation parts 45C and 46C are moved in a direction approaching each other toward the recessed grooves 521C and 531C portions defined by the wall parts 525C and 535C, so that the pins 422 and 432 of the first shaft member 42C and the second shaft member 43C can be removed from the holes 16 of the cover 11. Therefore, in this first state, the end link 50C is slid in the X-axis direction relative to the cover 11, and the pins 422 and 432 of the first shaft member 42C and the second shaft member 43C are inserted into the other holes 16 of the cover 11, so that the length of the band can be adjusted.

[0047] After the pins 422, 432 are inserted into the holes 16 of the cover 11, the operating parts 45C, 46C are rotated 90 degrees in the X1 direction to the second state as shown in FIG. 17. In this second state, the operating parts 45C, 46C are restricted by the walls 525C, 535C and restricted from moving in a direction toward each other. Therefore, in the second state, the pins 422, 432 of the first shaft member 42C and the second shaft member 43C can be restricted from coming out of the holes 16 of the cover 11. The walls 525C, 535C provided on the end link 50C are restricting parts that restrict the movement of the operating parts 45C, 46C. The holes 16 of the cover 11 may be formed at positions that do not interfere with the button unit 20 even when the operation portions 45C, 46C are in the second state.

[0048] [Effects of the sixth embodiment] According to the band of the sixth embodiment, the end link 50C is composed of two components, a first link 51C and a second link 61C, and two operating portions 45C, 46C are provided on the spring bar 40C, so that the same effect as the fifth embodiment can be achieved. Moreover, by cutting out both end portions of the wall portions 525C, 535C in the Y-axis direction, the operation portions 45C, 46C can be rotated in the X1 direction to the second state. Therefore, the movement of the operation portions 45C, 46C in the Y-axis direction can be restricted by the wall portions 525C, 535C, which are restricting portions, and the pins 422, 432 of the first shaft member 42C and the second shaft member 43C can be restricted from unintentionally coming out of the holes 16 of the cover 11. Moreover, the first state and the second state can be switched simply by rotating the operation portions 45C, 46C, so that the user can easily operate it.

[0049] [Seventh embodiment] As shown in Figures 18 and 19, the band of the seventh embodiment differs from the fifth and sixth embodiments in that it uses an end link 50D and a spring bar 40D as an engaging member, and in particular in that grooves are formed in the end link 50D to regulate the rotational movement of the operating portions 45D, 46D of the spring bar 40D. The end link 50D is configured to include a first link 51D and a second link 61D. The first link 51D is made of a metal material and includes a first arm portion 52D, a second arm portion 53D, and a connecting portion 54D.

[0050] The first arm portion 52D includes a first through hole 521D, a first guide groove 522D, a first restricting portion 526D, and a first engagement groove 527D. The first through hole 521D is formed penetrating the first arm 52D in the Y-axis direction, and the pipe 41D of the spring bar 40D is inserted into the first guide groove 522D. The first engagement groove 527D is connected to the first through hole 521D and opens to the upper surface of the first arm 52D. The first restriction portion 526D divides the first guide groove 522D and the first engagement groove 527D, and restricts the operation portion 45D, which is biased by the coil spring and has the pin 422 of the first shaft member 42D inserted into the hole 16, from rotating and moving from one side of the first guide groove 522D and the first engagement groove 527D to the other side. A space is provided between the first regulating portion 526D and the second piece 61D in which the operating portion 45D can move, and is configured so that when the operating portion 45D is moved in the Y2 direction, the operating portion 45D can rotate and move from one side of the first guide groove 522D and the first engagement groove 527D to the other side.

[0051] The second arm portion 53D includes a second through hole (not shown), a second guide groove 532D, a second restricting portion 536D, and a second engagement groove 537D. These configurations are the same as those of the first arm portion 52D, and therefore description thereof will be omitted. In addition, the first arm 52D and the second arm 53D are formed with a fixing hole through which a pin for connecting to the second link 61D is inserted and a connecting hole through which a pin for connecting to the middle link 3A is inserted, but since these are the same as in the fourth, fifth and sixth embodiments, their explanation will be omitted. The connecting portion 54D connects the first arm portion 52D and the second arm portion 53D, similar to the connecting portions 54, 54B, and 54C of the fourth, fifth, and sixth embodiments, and the side surface of the connecting portion 54D is an inclined surface.

[0052] The second link 61D of the end link 50D has the same configuration as the second links 61B and 61C of the fifth and sixth embodiments, and therefore a description thereof will be omitted. The spring bar 40D, like the spring bars 40B and 40C of the fifth and sixth embodiments, includes a pipe portion 41D, a first shaft member 42D, a second shaft member 43D, operating portions 45D and 46D, and a coil spring (not shown), and the operating portions 45D and 46D are arranged in long holes 411D and 412D of the pipe portion 41D.

[0053] The method of assembling the end link 50D and the method of attaching it to the second band 2 are the same as those in the fifth and sixth embodiments, and therefore the description will be omitted. The method of attaching and detaching the end link 50D to and from the cover 11 is also the same as that in the fifth embodiment. That is, in the first state in which the operation parts 45D and 46D of the end link 50D provided at the end of the second band 2 are oriented in the Z1 direction as shown in FIG. 18, the operation parts 45D and 46D are moved in a direction approaching each other along the first guide groove 522D and the second guide groove 532D, so that the pins 422 and 432 of the first shaft member 42D and the second shaft member 43D can be removed from the holes 16 of the cover 11. Therefore, in this state, the end link 50D is slid in the X-axis direction relative to the cover 11, and the pins 422 and 432 are inserted into the other holes 16 of the cover 11, so that the length of the band can be adjusted.

[0054] Furthermore, after the pins 422, 432 of the first shaft member 42D and the second shaft member 43D are inserted into the holes 16 of the cover 11, the operation portions 45D, 46D are moved in directions approaching each other to positions where they do not interfere with the first restriction portion 526D and the second restriction portion 536D, and the operation portions 45D, 46D are rotated 90 degrees in the X1 direction as shown in Fig. 19. Next, when the operation of the operation portions 45D, 46D is released, the first shaft member 42D and the second shaft member 43D move toward the first side surface portion 131 and the second side surface portion 132 of the cover 11 due to the biasing force of the coil spring. 19, in the second state in which the operating units 45D, 46D face the X1 direction, the operating units 45D, 46D engage with the first engagement groove 527D and the second engagement groove 537D, thereby restricting the rotation of the operating units 45D, 46D. Also, since the operating units 45D, 46D in the second state are disposed between the first side surface portion 131 and the second side surface portion 132 of the cover 11, it is possible to prevent the operating units 45D, 46D from moving unintentionally by the user. In addition, the lengths of the first regulating part 526D and the second regulating part 536D in the Y-axis direction are set so that when the operating parts 45D, 46D are moved to a position where they do not interfere with the first regulating part 526D and the second regulating part 536D, the pins 422, 432 do not come completely out of the hole 16, and the tips of the pins 422, 432 can be maintained inserted into the hole 16.

[0055] [Effects of the Seventh Embodiment] According to the band of the seventh embodiment, the end link 50D is composed of two components, the first link 51D and the second link 61D, and two operating portions 45D, 46D are provided on the spring bar 40D, so that the same effects as those of the fifth and sixth embodiments can be achieved. In addition, the operating units 45D, 46D can be rotated to place them in a first state and a second state, so that the user can select between the first state in which the operating units 45D, 46D can be moved in the Y-axis direction to easily insert and remove the pins 422, 432 of the first shaft member 42D and the second shaft member 43D into and from the holes 16 of the cover 11, and the second state in which unintentional movement of the operating units 45D, 46D in the Y-axis direction can be prevented.

[0056] [Eighth embodiment] As shown in Figures 20 and 21, the band of the eighth embodiment differs from the fourth embodiment in that it uses an end link 50E and a spring bar 40E as an engaging member, and in particular in that a groove is formed in the end link 50E to hold the operating portion 45E of the spring bar 40E when it is moved in the rotational direction. The end link 50E is different from the end link 50 of the fourth embodiment in that the first groove portion 522E is formed in an L-shape in plan view, but the other configurations are similar. That is, the end link 50E includes a first link 51E and a second link 61E, and the first link 51E is made of a metal material and includes a first arm portion 52E, a second arm portion 53E, and a connecting portion 54E.

[0057] The first arm 52E has a configuration similar to that of the first arm 52 of the end link 50, and is formed with a first through hole, a fixing hole, and a connecting hole (not shown). The first arm 52E also has a first groove 522E that opens on the upper surface of the first arm 52 and communicates with the first through hole 521. The first groove 522E is formed in an L-shape in plan view, with a groove along the Y-axis direction and a groove along the X-axis direction communicating with each other.

[0058] The second arm portion 53E and the connecting portion 54E have the same configuration as the second arm portion 53 and the connecting portion 54 of the end link 50, and therefore a description thereof will be omitted.

[0059] The second link 61E of the end link 50E has the same configuration as the second link 61 of the end link 50, and has a groove portion 612E that is continuous with the first groove portion 522E. A spring bar 40E, which is an engagement member, is inserted into the through hole of the second link 61E. The structure of the spring bar 40E is the same as that of the first and fourth embodiments, and therefore a description thereof will be omitted.

[0060] The clasp body 10E of the eighth embodiment includes a cover 11E and a button unit 20, similar to the clasp body 10 of the first embodiment, and the cover 11E includes a bottom portion 12E, a first side portion 131E, and a second side portion 132E. The first side portion 131E and the second side portion 132E are formed with a hole 15E into which a spring bar 93 for connecting the bending members is inserted, and a hole 16E into which each pin of the spring bar 40E is engaged. The hole 16E is a blind hole that does not pass through the first side portion 131E and the second side portion 132E, and the hole 16E is not exposed on the surface of the first side portion 131E and the second side portion 132E.

[0061] The method of assembling the end link 50E and the method of attaching it to the second band 2 are the same as those in the fourth embodiment, and therefore the description thereof will be omitted. In addition, the method of attaching and detaching the end link 50E from the cover 11 to adjust the band length is also the same as those in the fourth embodiment, and therefore the description thereof will be omitted.

[0062] In addition, when the operating part 45E of the spring bar 40E is biased in the Y1 direction by the coil spring and the pins, which are the engagement parts of the first shaft member and the second shaft member (not shown), are inserted into the hole 16E of the cover 11E, the operating part 45E is rotated in the X2 direction, as shown in FIG. 21, in which the operating part 45E is stored in the first groove portion 522E of the end link 50E. In this second state, the operating part 45E is stored in the first groove portion 522E and restricted from moving in the Y2 direction, which prevents the operating part 45E from moving unintentionally and causing the pins of the spring bar 40E to come out of the hole 16E. Therefore, the first groove portion 522E of the end link 50E forms a restricting portion that restricts the movement of the operating part 45E in the Y2 direction, which reliably prevents the pins from coming out of the hole 16E.

[0063] [Effects of the eighth embodiment] According to the band of the eighth embodiment, since the end link 50E is composed of two members, the first link 51E and the second link 61E, it is possible to obtain the same effects as those of the fourth embodiment. Furthermore, by forming the first groove portion 522E in the end link 50E, the user can select between a first state in which the operating portion 45E is movable in the Y-axis direction, and a second state in which movement in the Y-axis direction is restricted.

[0064] In the second state, the operating part 45E hardly protrudes from the top surface of the end link 50E, so it can be overlapped in plan with the outer plate 92 of the bending member 9. For this reason, when the wristwatch 100 is worn on the user's wrist, the bending member 9 and the operating part 45E can be overlapped in plan, and since there is no need to position the operating part 45E to the side where it does not overlap with the bending member 9 in plan, it can also be used with narrow bands.

[0065] [Variations] The spring bar serving as the engaging member is not limited to the configuration of the above embodiment. For example, a flange may be formed on the pins 422 and 432, and the flange may be abutted against the inner surfaces of the first side surface portion 131 and the second side surface portion 132 of the cover 11. In this case, the flange abuts against the first side surface portion 131 and the second side surface portion 132, thereby restricting the protruding dimension of the pins 422 and 432 inserted into the holes 16 to a certain dimension or less, and therefore, the pins 422 and 432 can be reliably prevented from protruding from the holes 16. Furthermore, the engaging member is not limited to a spring bar, and the engaging portion is not limited to a round bar-shaped pin. In other words, the engaging member only needs to have an engaging portion that can engage with hole 16 of cover 11 and an operating portion that moves this engaging portion between an engaging position where it engages with hole 16 and a non-engaging position where it is disengaged from hole 16. The shape of the hole in cover 11 may be a rectangular opening, and the engaging portion may be configured to match the shape of the hole.

[0066] The method of assembling the first link 51, 51B, 51C, 51D, 51E and the second link 61, 61B, 61C, 61D, 61E of the end link 50, 50B, 50C, 50D, 50E is not limited to the method of assembling by rotating the first link 51, 51B, 51C, 51D, 51E and the second link 61, 61B, 61C, 61D, 61E relatively as in the above embodiment. For example, the second link 61, 61B, 61C, 61D, 61E may be moved in the Z-axis direction relative to the first link 51, 51B, 51C, 51D, 51E and assembled. The shape of the operation unit is not limited to that in the above embodiment. For example, the operation unit is not limited to an approximately spherical operation knob, and may be a flat plate having a planar elliptical shape.

[0067] The clasp is not limited to a three-fold type having a folding member, but may be any clasp that connects the first band 1 and the second band 2. The number of holes 16 formed in each side portion of the clasp cover is not limited to two as in the above embodiments, but may be three or more. By forming three or more holes, the band length can be adjusted in three or more stages. The material of the end links 30, 30A, 30B, the first links 51, 51B, 51C, 51D, 51E and the second links 61, 61B, 61C, 61D, 61E of the end links 50, 50B, 50C, 50D, 50E is not limited to metal, but may be ceramic, synthetic resin, etc. Similarly, the material of the links 3 of the first band 1 and the second band 2 is not limited to metal, but may be ceramic, synthetic resin, etc. Furthermore, the first links 51, 51B, 51C, 51D, 51E and the second links 61, 61B, 61C, 61D, 61E, the center links 3A and the outer links 3B may be made of the same material or different materials, and the design variations can be expanded by combining each material.

[0068] [Summary of this disclosure] The band of the present disclosure comprises a first band, a second band, and a clasp connecting the first band and the second band, the clasp having a cover with a bottom portion and a side portion, the second band having an end link provided at an end on the clasp side and an engaging member held by the end link and engaging with the cover, the side portion having a plurality of holes formed along the longitudinal direction of the second band, and the engaging member having an engaging portion capable of engaging with the holes in the side portion and an operating portion for moving the engaging portion in the width direction of the second band between an engaging position where it engages with the hole and a non-engaging position where it is disengaged from the hole. The length of the band can be adjusted by changing the engagement position between the cover and the end link by operating the operating part of the engagement member held by the end link, moving the engagement part of the engagement member to a disengaged position, and engaging the engagement part with a hole selected from the multiple holes formed in the cover. Therefore, the user can easily adjust the band length by operating the operating part, and there is no need to use a dedicated adjustment tool, so the engagement part of the engagement member can be easily attached and detached to the cover, and the band length adjustment operation can also be easily performed. Since a dedicated adjustment tool is not required and the number of parts is small, manufacturing costs can be reduced. Furthermore, since the structure for adjusting the band length is simple, it can be easily manufactured.

[0069] In the band of the present disclosure, it is preferable to have a restricting portion that prevents the operating portion from moving from the engaged position to the disengaged position. Since the restricting portion prevents the operating portion from moving from the engaged position to the disengaged position, it is possible to reliably prevent the end link from coming out of engagement with the cover while the band is in use.

[0070] In the band of the present disclosure, it is preferable that the clasp has a clasp body and a bending member connecting the clasp body and the first band, the restricting portion is provided on the bending member, and the movement of the operating portion is restricted by the bending member when the clasp is closed. Since the restricting portion is made of a folding member, there is no need to provide additional parts that constitute the restricting portion, which reduces costs. Also, when the user is wearing the band, the clasp is closed and the folding member is folded, so the engaging member does not come off the cover while the band is in use, and it is possible to reliably prevent the band from unintentionally coming off due to disengagement. Furthermore, since the operation of closing the clasp is performed when the band is worn, a special operation for restricting the operating portion is also not required.

[0071] In the band of the present disclosure, it is preferable that the regulating portion is provided on the end link, and the engaging member is rotatably arranged between a regulating position in which the operating portion is regulated by the regulating portion and a non-regulating position in which the operating portion is not regulated by the regulating portion. Since the restricting portion is composed of an end link, there is no need to provide additional parts constituting the restricting portion, and costs can be reduced. In addition, by rotating the operating portion of the engaging member to move it from the non-restricting position to the restricting position, the engaging member can be reliably restricted from coming off the cover. Furthermore, by rotating the operating portion of the engaging member to move it from the restricting position to the non-restricting position, the operation of operating the operating portion to remove the engaging member from the cover and adjust the band length can be reliably performed.

[0072] In the band of the present disclosure, it is preferable that the clasp has a clasp body and a folding member connecting the clasp body and the first band, and when viewed from the side with the clasp closed, the length from the center axis of the engagement portion engaged with the hole of the cover to the tip of the operating portion is less than or equal to the length from the center axis to the surface of the folding member. According to the band of the present disclosure, when the clasp is closed, the operating part does not protrude from the surface of the folding member, i.e., on the user's wrist side, thereby preventing the operating part from hitting the user's wrist and impairing the wearing comfort.

[0073] In the band of the present disclosure, it is preferable that the length from the central axis of the engagement portion engaged with the hole of the cover to the tip of the operating portion is less than or equal to the length from the central axis to the free end in the thickness direction of the side portion. According to the band of the present disclosure, the operating portion is hidden by the cover in a side view, thereby improving the appearance.

[0074] In the band of the present disclosure, it is preferable that the length of the engagement portion is shorter than the thickness of the side portion. According to the band of the present disclosure, the engagement portion can be prevented from protruding outward from the cover, thereby improving the appearance of the cover.

[0075] In the band of the present disclosure, it is preferable that the hole provided in the side portion is a blind hole that does not penetrate through the side portion. According to the band of the present disclosure, the cover is formed with blind holes instead of through holes, so that the holes are not exposed to the outside of the cover, improving the appearance of the cover. Also, even if the cover does not have through holes, the engaging portion can be disengaged from the hole of the cover by operating the operating portion.

[0076] In the band of the present disclosure, it is preferable that the end link is configured to include a first link and a second link, and the engaging member is held by the first link and the second link. According to the band of the present disclosure, the end link is composed of a first link and a second link, so that the engaging member with the operating portion attached can be assembled with the operating portion positioned between the first link and the second link, improving ease of assembly.

[0077] In the band of the present disclosure, it is preferable that the operating portion is provided on each of both ends of the engaging member. According to the band of the present disclosure, the engagement portions at both ends of the engagement member can be moved separately using each operating portion, making it easier to attach and detach the engagement member from the cover compared to when there is only one operating portion.

[0078] In the band of the present disclosure, it is preferable that the operating portion is movable between a first state in which it faces in a direction intersecting the longitudinal direction of the second band, and a second state in which it faces in a direction along the longitudinal direction of the second band. According to the band of the present disclosure, the operating part can be moved between a first state and a second state by rotating the operating part around the axis of the engagement member. In the second state, the operating part faces in a direction along the longitudinal direction of the second band, making it more difficult to operate than in the first state. This reduces the risk that the user will operate the operating part by mistake. In addition, in the second state, the operating part does not protrude in the thickness direction of the second band, and the operating part can be moved to a position where it does not interfere with the folding member, so that the folding member and the operating part can be overlapped in a planar view, and since there is no need to place the operating part on the side where it does not overlap with the folding member in a planar view, it can be used for a narrow band.

[0079] In the band of the present disclosure, it is preferable that the operating portion is disposed in a groove provided in the end link in the second state. According to the band of the present disclosure, the operating portion is positioned within the groove of the end link, so that the user will not accidentally touch the operating portion, and unintended force applied to the operating portion can be prevented from causing the end link to unintentionally come off the cover.

[0080] In the band of the present disclosure, it is preferable that in the first state, the operating portion is movable to the engaged position and the disengaged position, and in the second state, movement from the engaged position to the disengaged position is restricted. According to the band of the present disclosure, in the second state, the operating part is restricted from being moved to the disengaged position, so that even if the user accidentally touches the operating part, the second band can be reliably prevented from coming off the clasp.

[0081] The watch of the present disclosure is characterized by having the band described above. According to the timepiece of the present disclosure, since it is equipped with the band described above, the user can easily adjust the band length. [Explanation of symbols]
