Detailed Description

First embodiment

Hereinafter, a first embodiment will be described with reference to the drawings.

As shown in fig. 1, a wristwatch 100 as a timepiece includes an exterior case 101, a first band 1, and a second band 2. The ears 102 are integrally provided in the 6 o 'clock direction and the 12 o' clock direction of the outer case 101, respectively. The first band 1 is coupled to the 6 o 'clock ear 102 using a mounting pin, and the second band 2 is coupled to the 12 o' clock ear 102 using a mounting pin.

As shown in fig. 2, the first band 1 and the second band 2 are assembled by connecting a plurality of band segments 3 each including a band segment 3A and an outer band segment 3B. An end connector 30A is provided at the open end of the first band 1, and an end connector 30 is provided at the open end of the second band 2 as shown in fig. 3, and these end connectors 30, 30A are connected by the clasp 5 shown in fig. 2 to 5.

The clasp 5 is a three-fold clasp having an intermediate folding member 9. Fig. 2 is a perspective view of the clasp 5 in a state where the intermediate folding member 9 is opened, fig. 3 is an exploded perspective view showing the clasp 5 and the end coupling 30, and fig. 4 is a perspective view showing a rear surface side of the cover 11 of the clasp, with a part thereof exploded.

In each of the drawings, an axis along the longitudinal direction of the first band 1 and the second band 2 is referred to as an X axis, an axis perpendicular to the X axis and along the width direction of the first band 1 and the second band 2 is referred to as a Y axis, and an axis perpendicular to the X axis and the Y axis is referred to as a Z axis. The direction from the clasp 5 toward the first band 1 on the X axis is defined as the X1 direction, and the direction from the clasp 5 toward the second band 2 is defined as the X2 direction. The direction from the widthwise center of the cover 11 toward the first side surface portion 131 side on the Y axis is referred to as the Y1 direction, and the direction toward the second side surface portion 132 side is referred to as the Y2 direction. In the Z axis, the direction in which the first side surface portion 131 and the second side surface portion 132 extend from the bottom surface portion 12 of the cover 11 is referred to as the Z1 direction, and the opposite direction is referred to as the Z2 direction. Here, when the wristwatch 100 is worn on the wrist of the user, the direction Z1 is sometimes referred to as the upper direction and the direction Z2 as the lower direction because the direction Z1 is on the outer case 101 side in the clasp 5. In each member, the surface on the Z1 direction side may be referred to as an upper surface, and the surface on the Z2 direction side may be referred to as a bottom surface.

As shown in fig. 2 to 4, the clasp 5 includes an intermediate folding member 9 and a clasp body 10.

The intermediate folding member 9 is a general intermediate folding member including an outer panel 92 and a middle panel 91 having a hook 94, and therefore, description thereof is omitted.

[ Structure of the Main body of the watch button ]

As shown in fig. 2 to 4, the clasp body 10 includes a cover 11 and a button unit 20.

As shown in fig. 2 to 4, the cover 11 includes a plate-shaped bottom surface portion 12 curved in an arc shape along the X1 direction and the X2 direction, and a first side surface portion 131 and a second side surface portion 132 protruding in the Z1 direction from outer edges of the bottom surface portion 12 in the Y1 direction and the Y2 direction.

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 surface portion 131 and the second side surface portion 132 are formed with: a hole 15 for mounting a spring rod 93, the spring rod 93 being coupled to the outer plate 92; and a hole 16 for mounting an end link 30 of the second wristband 2. In the present embodiment, two holes 16 are formed in the first side surface portion 131 and the second side surface portion 132 so as to be separated from each other in the X-axis direction, and the length of the second band 2 extending from the clasp body 10 can be adjusted to two stages by attaching the end links 30 to any one of the holes 16.

The button unit 20 includes a first button 21, a second button 22, a case 23 accommodating the first button 21 and the second button 22, and a coil spring (not shown) for biasing 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 protruding from the through hole 14 by coil springs, not shown. The first button 21 and the second button 22 are formed with engagement pieces 21A and 22A having a flat L shape. The engaging piece 21A is disposed between the second button 22 and the engaging piece 22A, and the engaging piece 22A is disposed between the first button 21 and the engaging piece 21A. Therefore, the engaging pieces 21A and 22A are configured to approach each other when the first button 21 and the second button 22 are biased in the direction of separating from each other by the coil spring, and to separate from each other when the first button 21 and the second button 22 are pushed in. An elliptical opening 24 is formed in the center of the surface of the case 23, and when the intermediate folding member 9 is folded and closed, the hook 94 of the intermediate plate 91 is inserted between the engaging pieces 21A, 22A from the opening 24, the umbrella-shaped portions at the ends of the hook 94 push the engaging pieces 21A, 22A against the urging force of the coil springs, and when the umbrella-shaped portions pass over the engaging pieces 21A, 22A, the engaging pieces 21A, 22A clamp the shaft portions of the hook 94 by the urging force of the coil springs, and the hook 94 is held by the engaging pieces 21A, 22A.

When the user presses the first button 21 and the second button 22, the engaging pieces 21A and 22A are separated from each other, and therefore the hook 94 can be removed to open the intermediate folding member 9.

[ End connector of second watchband ]

Next, the end link 30 of the second band 2 will be described with reference to fig. 4.

The end connector 30 is detachably attached to the cover 11 via a spring lever 40 with a lever as an engaging member.

The end connector 30 is formed by machining a pure metal material by cutting or the like. The end connector 30 includes a main body 31, and first and second arm portions 32 and 33 extending in the X2 direction from both end portions of the main body 31 in the Y axis direction.

A through hole 34 penetrating in the Y-axis direction is formed in the main body 31. A groove 35 that opens to the upper surface of the first arm 32 is formed in the end of the body 31 on the side of the first arm 32, and the groove 35 communicates with the through hole 34.

The first arm portion 32 and the second arm portion 33 are formed with a through hole 36 penetrating in the Y-axis direction. The middle band 3A of the middle band 3 is disposed between the first arm 32 and the second arm 33, and the first arm 32, the second arm 33, and the middle band 3A are connected by a pin 37 penetrating through the through hole 36 and the middle band 3A.

The spring lever 40 includes a tube 41, a first shaft member 42, a second shaft member 43, and a coil spring 44. The tube portion 41 is formed in a cylindrical shape, and has a long hole 411 formed at one end side. The left and right ends of the tube portion 41 are formed as openings smaller in diameter than the intermediate portion.

The first shaft member 42 includes: a shaft portion 421 having a diameter larger than the diameter of the end opening of the tube portion 41 and disposed in the tube portion 41; and a pin 422 protruding from the shaft portion 421 and protruding from an end opening of the tube portion 41, and inserted into the hole 16 of the first side surface portion 131. The shaft portion 421 of the first shaft member 42 is fixed with a rod-shaped operation portion 45 protruding from the long hole 411 by a screw or press-fitting.

The second shaft member 43 includes: a shaft portion 431 having a diameter larger than the diameter of the end opening of the pipe portion 41 and disposed in the pipe portion 41; and a pin 432 protruding from the shaft portion 431 and protruding from an end opening of the pipe portion 41, and inserted into the hole 16 of the second side surface portion 132. The pins 422 and 432 of the first shaft member 42 and the second shaft member 43 are engagement portions that can be engaged with the holes 16 of the cover 11, and the same applies to the following embodiments.

The coil spring 44 is disposed between the first shaft member 42 and the second shaft member 43 in the tube 41, and the pins 422 and 432 of the first shaft member 42 and the second shaft member 43 are set to protrude from both end openings of the tube 41. At this time, when the operating portion 45 is positioned at the end of the long hole 411 on the pin 422 side and the operating portion 45 is slid toward the second shaft member 43 to compress the coil spring 44, the first shaft member 42 to which the operating portion 45 is fixed is also moved toward the second shaft member 43 side, and the protruding dimension of the pin 422 from the pipe portion 41 is reduced.

As shown in fig. 5, the operation unit 45 is configured such that when the intermediate folding member 9 is folded and the clasp 5 is closed, the movement of the operation unit 45 in the Y2 direction is restricted by the side surface 921 of the outer panel 92. That is, the intermediate folded member 9 is a restricting portion that restricts the operation portion 45 from being accidentally moved in the Y2 direction so that the pin 422 of the first shaft member 42 of the spring lever 40 is disengaged from the hole 16.

As shown in fig. 6, when the clasp 5 is viewed from the side view in the Y-axis direction, the length L1 from the central axis of the pin 422 engaged with the hole 16 of the cover 11 of the first shaft member 42 to the end of the operation portion 45 is equal to or less than the length L2 from the central axis of the pin 422 to the surface 922 of the intermediate folded member 9 in the folded state. The surface 922 of the intermediate folding member 9 is a surface in the Z1 direction, and is a surface that contacts the wrist of the user when the wristwatch 100 is worn. Therefore, when the clasp 5 and the wristband with the intermediate folding member 9 folded are used, the operation portion 45 does not protrude from the intermediate folding member 9 and is brought into contact with the wrist of the user.

As shown in fig. 7, the maximum protruding dimension of the pins 422, 432 of the first and second shaft members 42, 43, that is, the length L3 of the pins 422, 432 protruding from the end portion of the tube portion 41 in a state where the first and second shaft members 42, 43 are biased in the direction of being separated from each other by the coil spring 44 is set to be shorter than the thickness T1 of the first and second side portions 131, 132 in which the hole 16 is formed. Thus, the pins 422 and 432 do not protrude from the hole 16 to the outside of the first side surface portion 131 and the second side surface portion 132, and the design can be improved.

[ Method for adjusting the length of watchband ]

Next, a method for adjusting the length of the band will be described. When the length of the band is adjusted, the clasp 5 is opened, and the outer panel 92 of the intermediate folding member 9 is moved from the restricting position for restricting the movement of the operation portion 45 to the non-restricting position for not restricting the movement of the operation portion 45. Then, the operation portion 45 is moved toward the second side surface portion 132, which is the Y2 direction, and the pin 422 is moved to the non-engagement position so as to be separated from the hole 16 of the first side surface portion 131. Then, the end portion of the end coupling 30 on the side of the operation portion 45 is moved in the Z1 direction (upward) with respect to the first side surface portion 131, and the first shaft member 42 of the spring lever 40 is tilted to a position not abutting against the first side surface portion 131. Accordingly, the spring lever 40 can be moved in the Y1 direction with respect to the end connector 30, and therefore the pin 432 can be disengaged from the hole 16 of the second side surface portion 132.

Next, the end link 30 is moved relative to the cover 11 in the X-axis direction, which is the longitudinal direction of the second band 2, the pin 432 of the second shaft member 43 is inserted into the other hole 16 formed in the cover 11, and the end of the end link 30 on the side of the operation portion 45 is moved in the Z2 direction with the first shaft member 42 moved in the Y2 direction by the operation portion 45, so that the pin 422 is aligned with the position of the hole 16 on the side of the first side portion 131, and the operation portion 45 is released. Then, the first shaft member 42 is moved in the Y1 direction by the coil spring 44, and the pin 422 is moved to the engagement position and inserted into the hole 16. By the above operation, the hole 16 of the cover 11 to which the spring lever 40 of the end link 30 is engaged can be selected, and therefore the length of the band can be adjusted.

[ Effect of the first embodiment ]

By operating the operating portion 45 of the spring lever 40, which is an engagement member held by the end link 30, the pin 422 of the first shaft member 42 is moved to the non-engagement position, and the pin 422 is engaged with the hole 16 selected from the plurality of holes 16 formed in the cover 11, whereby the engagement position between the cover 11 and the end link 30 can be changed to adjust the length of the wristband. Therefore, the user can easily adjust the length of the band by operating the operation unit 45, and a dedicated adjustment tool is not required, so that the pin 422 of the first shaft member 42 can be easily attached to and detached from the cover 11, and the adjustment operation of the length of the band can be easily performed.

Since no special adjustment member is required, the number of parts is small, and therefore, the manufacturing cost of the band including the first band 1, the second band 2, and the clasp 5 can be reduced. Further, since the structure for adjusting the length of the band is simple, the band can be easily manufactured.

As in the case of wearing the wristwatch 100 on the user, since the movement of the operation portion 45 is restricted by the intermediate folding member 9 in the state where the clasp 5 is closed, the operation portion 45 can be reliably prevented from being accidentally moved in the Y2 direction, and the pin 422 of the first shaft member 42 can be disengaged from the hole 16.

In the state where the clasp 5 is closed, the operation portion 45 does not protrude from the surface 922 of the intermediate folding member 9, and therefore, the operation portion 45 can be prevented from touching the wrist of the user to impair the wearing feeling.

Since the protruding dimension L3 of the pins 422 and 432 of the first shaft member 42 and the second shaft member 43 is equal to or smaller than the thickness T1 of the first side surface portion 131 and the second side surface portion 132, the pins 422 and 432 can be prevented from protruding outside the cover 11, and the appearance of the cover 11 can be improved.

Second embodiment

As shown in fig. 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, and the operation portion 45 is hidden in a side view. That is, the length L1 from the central axis of the pin 422 engaged with the hole 16 of the cover 11A of the first shaft member 42 to the tip of the operation section 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. Further, the free end 1311 of the first side surface portion 131 means: of the two end edges of the first side surface portion 131 that are provided separately in the Z-axis direction as the thickness direction, the end edge that is not connected to the bottom surface portion 12, but that is not connected to the bottom surface portion 12, refers to the upper surface of the first side surface portion 131 that faces the outer case 101 side.

Effect of the second embodiment

According to the wristband of the second embodiment, the same effects can be obtained by the same structure as the first embodiment. Further, the operation portion 45 is hidden by the cover 11A in side view, so that the appearance can be improved.

Third embodiment

As shown in fig. 9, the wristband of the third embodiment is different from the first and second embodiments in that the slot of the end link 30B in which the operation portion 45 is disposed is a long hole 35B. Accordingly, as shown in fig. 10, the spring rod 40 to which the operation portion 45 is not attached is inserted into the through hole 34B of the end coupling 30B, and thereafter, the operation portion 45 is fixed to the shaft portion 421 of the first shaft member 42 via the long hole 35B. For example, the operation portion 45 may be press-fitted into a hole formed in the shaft portion 421, or an external thread may be formed in the operation portion 45 and fixed by screwing with an internal thread formed in the shaft portion 421.

Effect of the third embodiment

According to the wristband of the third embodiment, the same effects can be obtained by the same structure as the first and second embodiments. Further, since the operation portion 45 is disposed in the long hole 35B with both ends closed, the spring lever 40 does not separate from the end link 30B when the end link 30B is detached from the cover 11 after the operation portion 45 is attached to the first shaft member 42. Therefore, the end connector 30B and the spring rod 40 can be integrated and easily handled.

Fourth embodiment

As shown in fig. 11 to 13, the band according to the fourth embodiment differs from the first to third embodiments in that the end connector 50 is constituted by two members, that is, the first band segment 51 and the second band segment 61. The structure of the clasp 5, the first band 1, and the second band 2 is the same as that of the first embodiment, and therefore, the description and illustration thereof are omitted.

The first strap section 51 of the end coupling 50 is made of a metal material, and includes a first arm section 52, a second arm section 53, and a coupling section 54, as shown in fig. 12.

The first arm 52 has a first through hole 521, a first groove 522, a fixing hole 523, and a connecting hole 524.

The first through hole 521, the fixing hole 523, and the connecting hole 524 are formed to penetrate the first arm 52 in the Y-axis direction.

The first groove 522 opens at the upper surface of the first arm 52 and communicates with the first through hole 521.

The second arm 53 has a second groove 531, a fixing hole 533, and a coupling hole 534. The second groove 531 is formed on the extension line of the first through hole 521 of the first arm 52 and the first groove 522, and penetrates the second arm 53 in the Y-axis direction and opens to the upper surface of the second arm 53. The bottom surface of the second groove 531 is formed in an arc shape like the first through hole 521.

The fixing hole 533 is a through hole that penetrates the second arm 53 in the Y-axis direction and is coaxial with the fixing hole 523. The coupling hole 534 is a through hole that penetrates the second arm 53 in the Y-axis direction and is coaxial with the coupling hole 524.

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 at the intermediate portion between the two end portions of the first arm portion 52 and the second arm portion 53 in the X-axis direction, and on the upper surface side in the Z1 direction. The side surface of the connecting portion 54 on the X1 direction side is an inclined surface 541.

The second band section 61 of the end connector 50 is made of a metal material, and has a through hole 611, a groove portion 612, a fixing hole 613, and a holding groove 615.

The through hole 611 is formed to penetrate the second belt segment 61 in the Y-axis direction. The groove portion 612 opens at the upper surface of the second belt segment 61 and communicates with the through hole 611. When the first band segment 51 and the second band segment 61 are assembled, the groove portion 612 is continuous with the first groove portion 522. The fixing hole 613 is formed to penetrate the second belt segment 61 in the Y-axis direction.

The holding groove 615 is a groove that opens on the upper surface of the second belt segment 61, and is formed so that the connecting portion 54 can be disposed.

A spring lever 40 as an engaging member is inserted into the through hole 611 of the second belt segment 61. Since the structure of the spring lever 40 is the same as that of the first embodiment, the same reference numerals are given and the description thereof is omitted.

As shown in fig. 13 (a), the first and second tie bars 51 and 61 are configured such that the first shaft member 42 side of the spring rod 40 is inserted into the first through hole 521 and the second shaft member 43 side is arranged in the second groove 531 in a state in which the spring rod 40 is inserted into the through hole 611 of the second tie bar 61. The operation portion 45 is disposed in the first groove 522.

Then, the first band segment 51 and the second band segment 61 are rotated relatively about the spring lever 40 as a rotation axis. At this time, since the inclined surface 541 is formed in the coupling portion 54, the coupling portion 54 can be disposed in the holding groove 615. Then, the pin 55 is inserted into the fixing holes 523, 613, 533, and the first strap section 51 and the second strap section 61 are coupled and fixed.

Further, the band 3A of the second band 2 is disposed between the first arm 52 and the second arm 53, and the pin 56 is inserted through the coupling holes 524 and 534 and the through hole formed in the band 3A to couple the end coupling 50 to the band 3A.

The end connector 50 provided at the end of the second band 2 is connected to the cover 11 by inserting the pins 422 and 432 of the first and second shaft members 42 and 43 into the holes 16 of the cover 11, as in the first embodiment. In addition, as in the first embodiment, the length of the band can be adjusted by operating the operating unit 45 to disengage the pins 422 and 432 from the holes 16 and inserting them into the other holes 16.

[ Effects of the fourth embodiment ]

According to the band of the fourth embodiment, since the end connector 50 is configured by two members, that is, the first band segment 51 and the second band segment 61, the spring lever 40, which is the engagement member in the state where the operation portion 45 is attached, can be arranged between the first band segment 51 and the second band segment 61 for assembly, and the ease of assembly of the end connector 50 can be improved.

Further, since the inclined surface 541 is formed in the coupling portion 54, the first strap section 51 and the second strap section 61 can be combined by relatively rotating about the spring lever 40 as the rotation axis, and the end coupling 50 can be easily assembled by inserting the pin 55 through the fixing holes 523, 613, 533.

Further, since the members of the end coupling 50 are divided into the first band segment 51 and the second band segment 61, for example, the first band segment 51 and the second band segment 61 can be made of different materials such as metal, ceramic, resin, and the like, and design variations can be enlarged.

Fifth embodiment

As shown in fig. 14 and 15, the wristband of the fifth embodiment is different from the fourth embodiment in that an end link 50B and a spring lever 40B as an engaging member are used.

The end coupling 50B is configured with a first strap section 51B and a second strap section 61B. The first strap section 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 has a first groove 521B, a fixing hole 523B, and a coupling hole 524B. The first groove 521B is a groove that penetrates the first arm 52B in the Y-axis direction and also opens on 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 tube 41B of the spring lever 40B.

The fixing hole 523B and the connecting hole 524B are formed to penetrate the first arm 52B in the Y-axis direction.

The second arm 53B has a second groove 531B, a fixing hole 533B, and a coupling hole 534B. Like the first groove 521B, the second groove 531B is a groove that penetrates the second arm 53B in the Y-axis direction and also opens at the upper surface of the second arm 53B. The bottom surface of the second groove 531B is formed in an arc shape similarly to the first groove 521B.

The fixing hole 533B and the coupling hole 534B are formed to penetrate the second arm 53B in the Y-axis direction.

The connecting portion 54B connects the first arm portion 52B and the second arm portion 53B in the same manner as the connecting portion 54 of the fourth embodiment, and the side surface of the connecting portion 54B is an inclined surface 541B similar to the inclined surface 541.

The second band section 61B of the end coupling 50B is made of a metal material, and has a groove portion 611B, a fixing hole 613B, and a holding groove 615B.

The groove portion 611B is formed to penetrate the second belt segment 61B in the Y-axis direction, and communicates with the holding groove 615B. That is, the groove 611B opens in the X2 direction. The bottom surface of the groove 611B on the X1 direction side is formed in an arc shape.

The fixing hole 613B is formed to penetrate the second belt segment 61B in the Y-axis direction.

The holding groove 615B is a groove that opens on the upper surface of the second belt segment 61B and communicates with the groove 611B, and is formed so that the coupling portion 54B can be disposed.

A spring lever 40B as an engagement member is inserted into the groove 611B of the second belt segment 61B. The spring lever 40B is similar to the spring lever 40 of the first embodiment, but is different in that the operation portions 45B, 46B are provided at both ends.

The spring lever 40B includes a tube portion 41B, a first shaft member 42B, a second shaft member 43B, and a coil spring, which is not shown. The tube portion 41B is formed in a cylindrical shape, and long holes 411B and 412B are formed at both ends in the longitudinal direction, respectively. The left and right ends of the tube portion 41B are formed as openings smaller in diameter than the intermediate portion.

The first shaft member 42B has the same structure as the first shaft member 42, and therefore, a description thereof will be omitted. An operation portion 45B protruding from the long hole 411B is attached to the first shaft member 42B.

The second shaft member 43B has the same structure as the first shaft member 42B, and an operation portion 46B protruding from the long hole 412B is attached to the second shaft member 43B. The operation portions 45B and 46B are the same as the operation portion 45, and therefore, description thereof is omitted.

The coil spring is disposed between the first shaft member 42B and the second shaft member 43B in the tube portion 41B, similarly to the spring rod 40 of the first embodiment. When the operating portions 45B and 46B are positioned on the end sides of the long holes 411B and 412B and the coil springs are compressed by sliding the operating portions 45B and 46B in the directions approaching each other, the first shaft member 42B and the second shaft member 43B are also moved in the directions approaching each other, and the pins 422 and 432 of the first shaft member 42B and the second shaft member 43B can be removed from the holes 16.

Next, a method of assembling the end coupling 50B will be described. The pre-assembled spring rod 40B is mounted to the groove portion 611B of the second band segment 61B. That is, as shown in fig. 15, the tube portion 41B of the spring rod 40B is moved from the holding groove 615B of the second band segment 61B to the groove portion 611B and is mounted.

Next, both ends of the spring rod 40B attached to the second band segment 61B are disposed in the first groove 521B and the second groove 531B of the first band segment 51B. Then, the first band segment 51B and the second band segment 61B are rotated relative to each other about the spring lever 40B as a rotation center, and the coupling portion 54B is disposed in the holding groove 615B. Then, the pin 55B is inserted through the fixing holes 523B, 613B, 533B, and the first strap section 51B and the second strap section 61B are coupled and fixed.

Further, the band 3A of the second band 2 is disposed between the first arm 52B and the second arm 53B, and the pin 56B is inserted through the coupling holes 524B and 534B and the through hole formed in the band 3A to couple the end coupling 50B to the band 3A.

The end connector 50B provided at the end of the second band 2 is connected to the cover 11 by inserting the pins 422 and 432 of the first and second shaft members 42B and 43B into the holes 16 of the cover 11 by operating the operating parts 45B and 46B. The length of the wristband can be adjusted by operating the operating units 45B and 46B to disengage the pins 422 and 432 of the first and second shaft members 42B and 43B from the holes 16, and sliding the end link 50B in the X-axis direction to insert the pins 422 and 432 into the other holes 16.

[ Effects of the fifth embodiment ]

According to the band of the fifth embodiment, since the end connector 50B is constituted by two members, that is, the first band segment 51B and the second band segment 61B, the same operational effects as those of the fourth embodiment can be achieved, and the assemblability of the end connector 50B can be improved.

Since the inclined surface 541B is formed in the coupling portion 54B, the end coupling 50B can be easily assembled by relatively rotating the first band segment 51B and the second band segment 61B about the spring rod 40B as the rotation axis and inserting the pin 55B into the fixing holes 523B, 613B, 533B as in the fourth embodiment.

Since the spring lever 40B has the operation portions 45B and 46B at both ends, both the first shaft member 42B and the second shaft member 43B can be moved by operating the operation portions 45B and 46B, and the end coupling 50B, which is the spring lever 40B, can be easily attached to and detached from the cover 11.

Since the first and second groove portions 521B and 531B are formed in the first and second tie bars 51B and 61B and the groove portion 611B communicating with the holding groove 615B is formed in the second tie bar 61B, the spring rod 40B can be easily attached to the first and second tie bars 51B and 61B.

Sixth embodiment

As shown in fig. 16 and 17, the band of the sixth embodiment is different from that of the fifth embodiment in that an end link 50C and a spring lever 40C as an engaging member are used.

The end connector 50C is configured to include a first band segment 51C and a second band segment 61C. The first strap section 51C is made of a metal material, and includes a first arm portion 52C, a second arm portion 53C, and a connecting portion 54C.

Grooves 521C and 531C penetrating in the Y-axis direction and opening to the upper surfaces of the first arm 52C and the second arm 53C are formed in the first arm 52C and the second arm 53C. At this time, the wall portions 525C, 535C defining the grooves 521C, 531C are cut out at both end portions in the Y axis direction at the end portions in the X1 direction of the first arm portion 52C and the second arm portion 53C.

The first arm 52C and the second arm 53C are formed with a fixing hole through which a pin for connecting with the second belt segment 61C is inserted and a connecting hole through which a pin for connecting with the belt segment 3A is inserted, but they are the same as those of the fourth and fifth embodiments, and therefore description thereof is omitted.

Like the connecting portions 54 and 54B of the fourth and fifth embodiments, the connecting portion 54C connects the first arm portion 52C and the second arm portion 53C, and the side surface of the connecting portion 54C is an inclined surface.

The second band segment 61C of the end coupling 50C has the same structure as the second band segment 61B of the fifth embodiment, and therefore, the description thereof is omitted.

The spring rod 40C is configured to include a tube portion 41C, a first shaft member 42C, a second shaft member 43C, operation portions 45C, 46C, and a coil spring, which is not shown, similarly to the spring rod 40B of the fifth embodiment. The operating portions 45C, 46C are disposed in the long holes 411C, 412C of the tube portion 41C.

The method of assembling the end links 50C and the method of attaching the end links to the second band 2 are the same as those of the fifth embodiment, and therefore, description thereof will be omitted. The method of attaching and detaching the end connector 50C to and from the cover 11 is also similar to the fifth embodiment. That is, as shown in fig. 16, the end link 50C provided at the end of the second band 2 can remove the pins 422, 432 of the first and second shaft members 42C, 43C from the hole 16 of the cover 11 by moving the operating portions 45C, 46C in the directions approaching each other in the grooves 521C, 531C divided by the wall portions 525C, 535C in the first state in which the operating portions 45C, 46C are directed in the Z1 direction. Therefore, in this first state, by sliding the end link 50C in the X-axis direction with respect to the cover 11, 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, whereby the length of the wristband can be adjusted.

After the pins 422 and 432 are inserted into the holes 16 of the cover 11, the operation portions 45C and 46C are rotated 90 degrees in the X1 direction to be in the second state as shown in fig. 17. In this second state, the operation portions 45C and 46C are restricted by the wall portions 525C and 535C, and are restricted from moving in the directions approaching each other. Accordingly, in the second state, the pins 422 and 432 of the first shaft member 42C and the second shaft member 43C can be restricted from being disengaged from the holes 16 of the cover 11. The wall portions 525C, 535C provided in the end coupling 50C are restricting portions that restrict movement of the operating portions 45C, 46C.

The hole 16 of the cover 11 may be formed at a position that does not interfere with the button unit 20 even when the operation portions 45C and 46C are in the second state.

[ Effect of the sixth embodiment ]

According to the band of the sixth embodiment, the end link 50C is constituted by two members, that is, the first band segment 51C and the second band segment 61C, and the two operation portions 45C and 46C are provided in the spring lever 40C, so that the same operational effects as those of the fifth embodiment can be obtained.

Further, by cutting off the 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 be brought into the second state. Accordingly, the movement of the operating portions 45C, 46C in the Y-axis direction can be restricted by the wall portions 525C, 535C serving as restricting portions, and the pins 422, 432 of the first shaft member 42C and the second shaft member 43C can be restricted from being accidentally disengaged from the hole 16 of the cover 11. Further, since the switching between the first state and the second state is only required to rotate the operation portions 45C and 46C, the user can easily perform the operation.

Seventh embodiment

As shown in fig. 18 and 19, the band of the seventh embodiment is different from the fifth and sixth embodiments in that an end link 50D and a spring lever 40D as an engaging member are used, and in particular, grooves for restricting movement of the operating portions 45D and 46D of the spring lever 40D in the rotational direction are formed in the end link 50D.

The end connector 50D is configured to include a first band segment 51D and a second band segment 61D. The first strap section 51D is made of a metal material, and includes a first arm portion 52D, a second arm portion 53D, and a connecting portion 54D.

The first arm 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 to penetrate the first arm portion 52D in the Y-axis direction, and the pipe portion 41D of the spring rod 40D is inserted. The first guide groove 522D communicates with the first through hole 521D, and opens at the upper surface of the first arm portion 52D. The first engagement groove 527D communicates with the first through hole 521D, and opens to the side surface of the first arm 52D in the X1 direction. The first regulating portion 526D defines a first guide groove 522D and a first engagement groove 527D, and regulates the rotational movement of the operating portion 45D in a state in which the pin 422 of the first shaft member 42D is urged by the coil spring and inserted into the hole 16 from one of the first guide groove 522D and the first engagement groove 527D to the other. A space in which the operation portion 45D is movable is provided between the first regulating portion 526D and the second belt segment 61D, and is formed as follows: in a state where the operation portion 45D is moved in the Y2 direction, the operation portion 45D can be rotated from one of the first guide groove 522D and the first engagement groove 527D to the other.

The second arm 53D includes a second through hole, a second guide groove 532D, a second restricting portion 536D, and a second engagement groove 537D, which are not shown. These structures are the same as the first arm portion 52D, and therefore, description thereof is omitted.

The first arm portion 52D and the second arm portion 53D are formed with a fixing hole through which a pin for connecting with the second belt segment 61D is inserted and a connecting hole through which a pin for connecting with the belt segment 3A is inserted, but they are the same as those of the fourth, fifth, and sixth embodiments, and therefore description thereof is omitted.

Like the connecting portions 54, 54B, and 54C of the fourth, fifth, and sixth embodiments, the connecting portion 54D connects the first arm portion 52D and the second arm portion 53D, and the side surface of the connecting portion 54D is an inclined surface.

The second band segment 61D of the end coupling 50D has the same structure as the second band segments 61B and 61C of the fifth and sixth embodiments, and therefore, the description thereof is omitted.

Like the spring levers 40B and 40C according to the fifth and sixth embodiments, the spring lever 40D includes a tube portion 41D, a first shaft member 42D, a second shaft member 43D, operation portions 45D and 46D, and coil springs, not shown, and the operation portions 45D and 46D are disposed in long holes 411D and 412D of the tube portion 41D.

The method of assembling the end links 50D and the method of attaching the end links to the second band 2 are the same as those of the fifth and sixth embodiments, and therefore, descriptions thereof are omitted. The method of attaching and detaching the end connector 50D to and from the cover 11 is also similar to the fifth embodiment. That is, as shown in fig. 18, the end connector 50D provided at the end of the second band 2 can remove the pins 422, 432 of the first shaft member 42D and the second shaft member 43D from the hole 16 of the cover 11 by moving the operating portions 45D, 46D in the directions approaching each other along the first guide groove 522D and the second guide groove 532D in the first state in which the operating portions 45D, 46D are directed in the Z1 direction. Accordingly, by sliding the end link 50D in the X-axis direction with respect to the cover 11 in this state, the pins 422 and 432 are inserted into the other holes 16 of the cover 11, and the length of the wristband can be adjusted.

After the pins 422 and 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 and 46D are moved in the directions approaching each other to positions where the operation portions do not interfere with the first restriction portion 526D and the second restriction portion 536D, and the operation portions 45D and 46D are rotated by 90 degrees in the X1 direction as shown in fig. 19. Next, when the operation of the operation portions 45D and 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 by the urging force of the coil springs.

As shown in fig. 19, in the second state in which the operation portions 45D and 46D are oriented in the X1 direction, the operation portions 45D and 46D are engaged with the first engagement groove 527D and the second engagement groove 537D, and thus the rotation of the operation portions 45D and 46D can be restricted. Further, since the second-state operation portions 45D and 46D are disposed between the first side surface portion 131 and the second side surface portion 132 of the cover 11, the user can be prevented from unconsciously moving the operation portions 45D and 46D.

The lengths of the first and second restricting portions 526D, 536D in the Y-axis direction are set to: when the operation portions 45D and 46D are moved to the positions where they do not interfere with the first and second restricting portions 526D and 536D, the pins 422 and 432 can be maintained in a state where the distal ends of the pins 422 and 432 are inserted into the holes 16 without being completely separated from the holes 16.

[ Effect of the seventh embodiment ]

According to the band of the seventh embodiment, the end connector 50D is constituted by two members, that is, the first band segment 51D and the second band segment 61D, and the two operation portions 45D and 46D are provided in the spring lever 40D, so that the same operational effects as those of the fifth and sixth embodiments can be obtained.

Further, since the operation portions 45D and 46D can be rotated and placed in the first state and the second state, the first state in which the operation portions 45D and 46D can be easily operated to move in the Y axis direction to insert the pins 422 and 432 of the first shaft member 42D and the second shaft member 43D into the hole 16 of the cover 11 or separate from the hole 16, and the second state in which an unexpected movement operation of the operation portions 45D and 46D in the Y axis direction can be prevented can be selected by the user's operation.

Eighth embodiment

As shown in fig. 20 and 21, the band according to the eighth embodiment is different from the fourth embodiment in that the end link 50E and the spring lever 40E as the engaging member are used, and in particular, in that a groove for holding the operation portion 45E of the spring lever 40E when moving in the rotational direction is formed in the end link 50E.

The end coupling 50E is different from the end coupling 50 of the fourth embodiment in that the first groove portion 522E is formed in a planar L-shape and the other structures are the same. That is, the end coupling 50E includes the first band segment 51E and the second band segment 61E, and the first band segment 51E is made of a metal material and includes the first arm portion 52E, the second arm portion 53E, and the coupling portion 54E.

The first arm 52E has the same structure as the first arm 52 of the end connector 50, and a first through hole, a fixing hole, and a connecting hole, which are not shown, are formed therein. The first arm 52E is formed with 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 a plane L shape by communicating a groove along the Y-axis direction with a groove along the X-axis direction.

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 coupling 50, and therefore, the description thereof will be omitted.

The second band section 61E of the end coupling 50E has the same structure as the second band section 61 of the end coupling 50, and has a groove portion 612E continuous with the first groove portion 522E.

A spring lever 40E as an engagement member is inserted into the through hole of the second band segment 61E. The spring lever 40E has the same structure as the first and fourth embodiments, and therefore, a description thereof will be omitted.

The button body 10E of the eighth embodiment includes a cover 11E and a button unit 20, similar to the button body 10 of the first embodiment, and the cover 11E includes a bottom surface portion 12E, a first side surface portion 131E, and a second side surface portion 132E. The first side surface portion 131E and the second side surface portion 132E are formed with holes 15E into which the spring rod 93 connecting the intermediate folding member is inserted and holes 16E into which the respective pins of the spring feeding rod 40E engage. The hole 16E is a blind hole that does not penetrate the first side surface portion 131E and the second side surface portion 132E, and the hole 16E is not exposed on the surfaces of the first side surface portion 131E and the second side surface portion 132E.

The method of assembling the end links 50E and the method of attaching the end links to the second band 2 are the same as those of the fourth embodiment, and therefore, descriptions thereof are omitted. The method of attaching and detaching the end link 50E to and from the cover 11 to adjust the length of the wristband is the same as that of the fourth embodiment, and therefore, the description thereof is omitted.

When the operation portion 45E of the spring lever 40E is rotated in the X2 direction with the respective pins, which are engagement portions of the first shaft member and the second shaft member, not shown, being inserted into the holes 16E of the cover 11E while being biased in the Y1 direction by the coil spring, the operation portion 45E is in a second state in which the operation portion 45E is accommodated in the first groove portion 522E of the end coupling 50E, as shown in fig. 21. In this second state, the operation portion 45E is accommodated in the first groove portion 522E and is restricted from moving in the Y2 direction, and the operation portion 45E can be prevented from moving accidentally and disengaging the pins of the spring lever 40E from the holes 16E. Therefore, the first groove 522E of the end coupling 50E constitutes a restriction portion that restricts movement of the operation portion 45E in the Y2 direction, and thus the pin can be reliably prevented from coming off the hole 16E.

[ Effect of the eighth embodiment ]

According to the band of the eighth embodiment, since the end connector 50E is configured by two members, that is, the first band segment 51E and the second band segment 61E, the same operational effects as those of the fourth embodiment can be achieved.

Further, by forming the first groove 522E in the end coupling 50E, the first state in which the operation portion 45E can be moved in the Y-axis direction and the second state in which the movement in the Y-axis direction is restricted can be selected by the user's operation.

In the second state, the operation portion 45E hardly protrudes from the upper surface of the end coupling 50E, and therefore can overlap the outer panel 92 of the intermediate folded member 9 in a plan view. Therefore, when the wristwatch 100 is worn on the wrist of the user, the intermediate folding member 9 and the operation portion 45E can be overlapped in a plan view, and the operation portion 45E does not need to be disposed on the side that does not overlap the intermediate folding member 9 in a plan view, so that the wristwatch can be used for a wristband having a relatively narrow width.

Modification example

The spring lever as the engaging member is not limited to the structure of the above embodiment. For example, the pins 422 and 432 may be formed with flanges, and the flanges may be brought into contact with 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 protruding dimension of the pins 422, 432 inserted into the holes 16 can be limited to a certain dimension or less by the abutment of the flange with the first side surface portion 131 and the second side surface portion 132, so that the pins 422, 432 can be reliably prevented from protruding from the holes 16.

The engagement member is not limited to the spring lever, and the engagement portion is not limited to the round bar-shaped pin. That is, the engaging member may have an engaging portion that can engage with the hole 16 of the cover 11, and may include an operating portion that moves the engaging portion between an engaging position that engages with the hole 16 and a non-engaging position that disengages from the hole 16. The hole of the cover 11 may be rectangular in shape, and the engagement portion may be formed in accordance with the shape of the hole.

The method of assembling the first strap sections 51, 51B, 51C, 51D, 51E and the second strap sections 61, 61B, 61C, 61D, 61E of the end connectors 50, 50B, 50C, 50D, 50E is not limited to the method of assembling the first strap sections 51, 51B, 51C, 51D, 51E and the second strap sections 61, 61B, 61C, 61D, 61E by relatively rotating them as in the above-described embodiment. For example, the second strap sections 61, 61B, 61C, 61D, 61E may be assembled by moving the first strap sections 51, 51B, 51C, 51D, 51E in the Z-axis direction.

The shape of the operation portion is not limited to the above embodiment. For example, the operation knob is not limited to a substantially spherical shape, and may be a flat plate shape having a planar oval shape.
