[0034] The watch band main body 2 is a main body portion of the watch band 1 wound around the user's arm, and has a plurality of decorative members 3, a connection ring 4, and a wire 5.

[0035] The decorative members 3 are composed of pearls, and a plurality of the decorative members 3 are linked by inserting the wire 5 composed of piano wire or the like into through holes provided in the pearls. In the present embodiment, the decorative members 3 are linked by the wire 5 in a manner of being arranged in two columns. Thus, the watch band 1 having high decorativeness is constituted. In addition, the decorative members 3 are not limited to the above structure, and may, for example, be composed of opal, agate, ruby, diamond, or the like, a shell such as white butterfly shell or black butterfly shell, or wood. In addition, the wire 5 can be composed of synthetic fiber such as nylon or silk thread, in addition to piano wire, as long as it can link the decorative members 3 in a wire shape.

[0036] The connection ring 4 is formed in a circular ring shape from a material such as metal, and the connection ring 4 is linked to both end portions of the decorative members 3 by linking the wire 5 to the connection ring 4, for example. Specifically, the connection ring 4 has two at one end portion of the watch band main body 2 and two at the other end portion. In the present embodiment, the connection ring 4 is disposed at the connection ring disposition portion 60 of the link member 10 described later, and is linked to the link member 10 by the fixing member 50 described later. Thus, the watch band main body 2 and the link member 10 are linked. In addition, the connection ring 4 can be formed in a ring shape from another material, or can be formed integrally with the wire 5 by linking the wire 5 in a ring shape.

[0037] [Link member]

[0038] The link member 10 has a spring lever 20, an outer block 30, an intermediate block 40, a fixing member 50, and a connection ring disposition portion 60.

[0039] [Spring lever]

[0040] The spring lever 20 is a member for linking the link member 10 to the pair of holding piece portions 112A, 112B in a detachable manner. In the present embodiment, the spring lever 20 has a shaft member 21, an operation portion 22, a first protruding member 23, a second protruding member 24, and a spring member 25. In addition, the spring lever 20 is inserted into the first arm recess portion 311, the intermediate block insertion hole 42, the intermediate block recess portion 41, the second arm recess portion 321, and the second arm insertion hole 322 described later.

[0041] In addition, the intermediate block insertion hole 42 and the second arm insertion hole 322 constitute the spring lever insertion hole of the present disclosure into which the spring lever 20 is inserted.

[0042] The shaft member 21 is made of metal and is cylindrical, and has openings at both end portions. Further, a long hole 211 is provided on the outer peripheral surface of the shaft member 21. In addition, the shaft member 21 is configured so that the length is substantially equal to the width direction length of the outer block 30, that is, the length from one side surface 313 of the first arm portion 31 to the other side surface 325 of the second arm portion 32.

[0043] The operation portion 22 is provided so as to protrude from the first protruding member 23 in a direction perpendicular to the axial direction O of the shaft member 21, and protrudes from the long hole 211 of the shaft member 21. In the present embodiment, the operation portion 22 is provided integrally with the first protruding member 23. Further, the operation portion 22 is configured so as to be movable within the long hole 211 in the axial direction O. Thus, the first protruding member 23 provided integrally with the operation portion 22 can be moved in the axial direction O, and therefore the link member 10 can be attached to or detached from the lug 112 of the timepiece 100. In other words, the long hole 211 is provided so as to have a length to the extent that the first protruding member 23 falls off from the hole portion 1121 of the lug 112 when the operation portion 22 is moved in the axial direction O. Further, the axial direction O is a direction perpendicular to the direction in which the band main body 2 of the band 1 extends.

[0044] In addition, the operation portion 22 is configured so as to protrude from the opening 47 of the intermediate block recess 41 described later when the spring bar 20 is housed in the outer block 30 and the intermediate block 40. Thus, in a state in which the spring bar 20 is housed in the outer block 30 and the intermediate block 40, the operation portion 22 can be moved in the axial direction O of the shaft member 21 within the intermediate block recess 41 and the second arm recess 321.

[0045] The base end portion of the first protruding member 23, which is provided so as to have a large diameter, is housed inside the shaft member 21. Further, the front end portion, which is provided so as to have a small diameter, protrudes in the axial direction O from the opening provided at one end portion of the shaft member 21.

[0046] In addition, the first protruding member 23 is biased by the spring member 25 so that the front end portion protrudes in the axial direction O of the shaft member 21. At this time, the first protruding member 23 is in a state in which the base end portion having a large diameter is engaged with the end portion of the shaft member 21.

[0047] Further, the first protruding member 23 is configured so that the front end portion protrudes in the axial direction O from the outer block 30 in a state in which the spring bar 20 is housed in the outer block 30 and the intermediate block 40.

[0048] The base end portion of the second protruding member 24, which is provided so as to have a large diameter, is housed inside the shaft member 21. Further, the front end portion, which is provided so as to have a small diameter, is configured so as to protrude in the axial direction O from the opening portion provided at the other end portion of the shaft member 21.

[0049] Additionally, the second protruding member 24 is forceped by the spring member 25 in such a way that it protrudes along the axial direction O of the shaft member 21. At this time, the second protruding member 24 is in a state where its large-diameter base end is engaged with the end of the shaft member 21.

[0050] Furthermore, the second protruding member 24 is configured such that, with the spring rod 20 housed within the outer block 30 and the intermediate block 40, its front end protrudes from the outer block 30. Additionally, the first protruding member 23 and the second protruding member 24 are examples of protruding members of this disclosure.

[0051] The spring component 25 is a so-called helical spring, housed inside the shaft component 21. Furthermore, the spring component 25 contacts the base end of the first protruding component 23 and the base end of the second protruding component 24, so that the first protruding component 23 and the second protruding component 24 respectively protrude from the shaft component 21 along the axial direction O and apply force.

[0057] Moreover, in the present embodiment, a curved portion 315 that is cut into a spherical shape is formed at the end portion of the first arm portion 31 on the side of the band main body 2. The curved portion 315 is formed so as to correspond to the spherical surface of the decorative member 3. Thus, when the corner portion of the first arm portion 31 comes into contact with the decorative member 3, it is possible to suppress damage to the corner portion of the first arm portion 31.

[0058] The second arm portion 32 is provided on the other end portion side of the main body portion 33. That is, the first arm portion 31 and the second arm portion 32 are arranged so as to sandwich the main body portion 33.

[0059] The second arm portion 32 is provided with a second arm recess portion 321, a second arm insertion hole 322, and a second arm fixing hole 323.

[0060] The second arm recess portion 321 is a recess portion in which the shaft member 21 of the spring bar 20 is arranged, and is provided along the axial direction O of the shaft member 21. In the present embodiment, the second arm recess portion 321 is provided from one side surface 324 of the second arm portion 32 to the vicinity of the center of the second arm portion 32. In addition, the second arm recess portion 321 is provided so as to correspond to the position of the intermediate block recess portion 41 of the intermediate block 40 described later, that is, so as to be adjacent to the intermediate block recess portion 41. Furthermore, the second arm recess portion 321 is provided so as to be open to the back surface side of the watch 100 when the band 1 is attached to the watch main body 110.

[0061] The second arm insertion hole 322 is a hole into which the shaft member 21 of the spring bar 20 is inserted, and is provided along the axial direction O of the shaft member 21. In the present embodiment, the second arm insertion hole 322 communicates with the second arm recess portion 321, and penetrates the second arm portion 32 from the second arm recess portion 321 to the other side surface 325 of the second arm portion 32. In addition, the second arm insertion hole 322 is an example of the first insertion hole of the present disclosure.

[0062] The second arm fixing hole 323 is a hole into which the fixing member 50 is inserted, and is provided along the axial direction of the pin 51 of the fixing member 50 described later. In the present embodiment, the second arm fixing hole 323 penetrates the second arm portion 32 from the one side surface 324 to the other side surface 325. Furthermore, the C-shaped ring 52 of the fixing member 50 described later is arranged in the second arm fixing hole 323.

[0063] Moreover, in the present embodiment, a curved portion 326 that is cut into a spherical shape is formed at the end portion of the second arm portion 32 on the side of the band main body 2. The curved portion 326 is formed so as to correspond to the spherical surface of the decorative member 3. Thus, when the corner portion of the second arm portion 32 comes into contact with the decorative member 3, it is possible to suppress damage to the corner portion of the second arm portion 32.

[0064] The main body portion 33 has a first main body plate portion 331 and a second main body plate portion 332 extending in a direction intersecting the first main body plate portion 331, and is formed in an L shape in a cross-sectional view. As described above, the first arm portion 31 is provided on one end portion side of the main body portion 33, and the second arm portion 32 is provided on the other end portion side, and the first arm portion 31 and the second arm portion 32 are connected.

[0065] In addition, in the present embodiment, the main body portion 33 is configured so that, when the watch band 1 is attached to the watch main body 110, the second main body plate portion 332 covers the intermediate block 40 and the connecting ring 4 when viewed from above in a direction that is substantially parallel to the length direction of the watch band 1 and is perpendicular to the surface of the second main body plate portion 332. Thus, the connecting ring 4 can be hidden, and thus it is possible to suppress a decrease in design of the watch band 1 due to exposure of the connecting ring 4. In addition, the second main body plate portion 332 is an example of a covering portion of the present disclosure.

[0066] [Intermediate Block]

[0067] The intermediate block 40 is a member for connecting with the outer block 30 to house the spring bar 20, and is disposed between the first arm portion 31 and the second arm portion 32 by the fixing member 50. In the present embodiment, the intermediate block 40 is formed by machining such as cutting of a solid metal material, and two portions on the side opposite to the decorative member 3 are cut away to be formed.

[0068] The intermediate block 40 is provided with an intermediate block recessed portion 41, an intermediate block through-hole 42, and an intermediate block fixing hole 43.

[0069] The intermediate block recessed portion 41 is a recessed portion in which the shaft member 21 of the spring bar 20 is disposed, and is provided along the axial direction O of the shaft member 21. In the present embodiment, the intermediate block recessed portion 41 is provided toward the center of the intermediate block 40 from the side surface 46 of the intermediate block 40. In addition, the intermediate block recessed portion 41 is provided adjacent to the second arm recessed portion 321 of the second arm portion 32. Further, the intermediate block recessed portion 41 is provided so as to open to the back surface side of the watch 100 when the watch band 1 is attached to the watch main body 110. In addition, the intermediate block recessed portion 41 is an example of a second recessed portion of the present disclosure.

[0070] The intermediate block through-hole 42 is a hole through which the shaft member 21 of the spring bar 20 is inserted, and is provided along the axial direction O of the shaft member 21.

In addition, the intermediate block through-hole 42 is provided from the side surface 45 of the intermediate block 40 to the intermediate block recessed portion 41. That is, the intermediate block through-hole 42 communicates with the intermediate block recessed portion 41.

[0071] Thus, in this embodiment, the first arm recess 311, the intermediate block insertion hole 42, the intermediate block recess 41, the second arm recess 321, and the second arm insertion hole 322 are arranged sequentially along the axial direction O. Furthermore, the intermediate block insertion hole 42 is an example of the second insertion hole of this disclosure.

[0072] The intermediate block fixing hole 43 is a hole for inserting the fixing component 50. It is set along the axial direction O of the pin 51 of the fixing component 50, which will be described later, and passes through the intermediate block 40.

[0073] Furthermore, in this embodiment, a first curved portion 48 and a second curved portion 49, cut into a spherical shape, are formed at the end of the intermediate block 40 on the side of the watch strap body 2. The first curved portion 48 and the second curved portion 49 are formed corresponding to the spherical surface of the decorative member 3. As a result, when the intermediate block 40 contacts the decorative member 3, corner defects of the intermediate block 40 can be suppressed.

[0074] [Fixed components]

[0075] The fixing member 50 is a component used to fix the intermediate block 40 between the first arm 31 and the second arm 32 of the outer block 30, and to connect the connecting member 10 to the watch strap body 2. In this embodiment, the fixing member 50 has a pin 51 and a C-ring 52.

[0076] The pin 51 is made of metal and is inserted into the first arm fixing hole 312, the connecting ring 4, the intermediate block fixing hole 43, and the second arm fixing hole 323. In addition, the pin 51 is configured such that its outer diameter is approximately equal to the inner diameter of the small diameter portion 3122 of the first arm fixing hole 312 and the intermediate block fixing hole 43.

[0077] The C-ring 52 is made of a metal such as stainless steel and, as described above, is disposed in the large-diameter portion 3121 of the first arm fixing hole 312 and the second arm fixing hole 323. Furthermore, a pin 51 is inserted into the inner side of the C-ring 52.

[0078] In addition, the first arm fixing hole 312, the intermediate block fixing hole 43 and the second arm fixing hole 323 constitute the fixing component insertion hole of the present disclosure for the fixing component 50 to be inserted.

[0079] [Connecting Ring Configuration Section]

[0080] The connecting ring configuration section 60 is a configuration section for configuring the connecting ring 4. In this embodiment, the connecting ring configuration section 60 is formed by two gaps between the outer block 30 and the intermediate block 40. Specifically, the connecting ring configuration section 60 is formed by the gap between the first arm 31 and the cut-off portion of the intermediate block 40, and the gap between the second arm 32 and the cut-off portion of the intermediate block 40.

[0081] [Assembly method of watchband 1]

[0082] Next, the assembly method of the watchband 1 will be described.

[0083] Figures 6 to 8 is a perspective view showing the assembly method of the watchband 1.

[0084] First, as shown in Figure 6 , the shaft member 21 of the spring bar 20 is inserted through the intermediate block insertion hole 42 of the intermediate block 40. By this, the spring bar 20 is arranged in the intermediate block recess 41 and the intermediate block insertion hole 42 of the intermediate block 40. At this time, the spring bar 20 is arranged so that the operation portion 22 protrudes from the opening 47 of the intermediate block recess 41.

[0085] Next, as shown in Figure 7 , the operation portion 22 of the spring bar 20 is moved in the axial direction O so that the operation portion 22 is engaged with the intermediate block 40. Then, the C-shaped ring 52 is arranged in the large diameter portion 3121 of the first arm fixing hole 312.

[0086] In this state, the intermediate block 40 is arranged between the first arm portion 31 and the second arm portion 32 of the outer block 30. At this time, the shaft member 21 of the spring bar 20 is arranged in the first arm recess 311 of the first arm portion 31.

[0087] Further, at this time, the first protruding member 23 is arranged in the second arm recess 321. That is, the intermediate block recess 41 is formed so that the front end portion of the first protruding member 23 protrudes from the side surface 46 of the intermediate block 40 in a state where the operation portion 22 is engaged with the intermediate block 40.

[0088] Therefore, in a state where the first protruding member 23 protrudes from the side surface 46 of the intermediate block 40, the first protruding member 23 does not interfere with the second arm portion 32, and thus the intermediate block 40 can be arranged between the first arm portion 31 and the second arm portion 32.

[0089] Next, as shown in Figure 8 , the operation portion 22 of the spring bar 20 is moved in the axial direction O so that the shaft member 21 is inserted into the second arm insertion hole 322 of the second arm portion 32. By this, for example, when the operation portion 22 is moved to the first arm portion 31 side, at a stage where a prescribed amount is moved, the operation portion 22 interferes with the intermediate block 40. Further, when the shaft member 21 is moved to the second arm portion 32 side, at a stage where a prescribed amount is moved, the operation portion 22 interferes with the second arm portion 32. Therefore, in a case where the operation portion 22 is moved in the axial direction O, the spring bar 20 can be prevented from falling off from the outer block 30 and the intermediate block 40.

[0090] Next, the connection ring 4 of the band main body 2 is arranged in the connection ring arrangement portion 60, and the C-shaped ring 52 is inserted into the second arm fixing hole 323.

[0091] And finally, the pin 51 is inserted into the first arm fixing hole 312, the connection ring 4, the intermediate block fixing hole 43, and the second arm fixing hole 323. In this way, the pin 51 is pressed into the large diameter portion 3121 of the first arm fixing hole 312 and the inside of the C-shaped ring 52 of the second arm fixing hole 323, and the C-shaped ring 52 is deformed toward the outer peripheral side. Thus, the C-shaped ring 52 is engaged with the large diameter portion 3121 of the first arm fixing hole 312 and the second arm fixing hole 323, and the pin 51 does not fall out of the first arm fixing hole 312, the connection ring 4, the intermediate block fixing hole 43, and the second arm fixing hole 323. Therefore, the intermediate block 40 is fixed to the outer block 30 by the fixing member 50, and the band main body 2 is linked to the link member 10.

[0092] [Rotation Restriction Structure]

[0093] Next, the rotation restriction structure of the band 1 will be described.

[0094] As shown in Figure 3 In the present embodiment, when a cross section of the band 1 is observed from the axial direction of the pin 51, the link member 10 is configured such that the normal line distance R of the second main plate portion 332 from the second main plate portion 332 of the main portion 33 to the axial center of the pin 51 of the fixing member 50 is shorter than the distance L from the axial center of the pin 51 to the end portion of the intermediate block 40 on the side of the decoration member 3. More specifically, the distance L is the distance from the point at which an imaginary line intersects the surface of the intermediate block 40 to the axial center of the pin 51, the imaginary line connecting from the axial center of the pin 51 to the end portion of the second main plate portion 332 on the side of the decoration member 3. In addition, when viewed from above, the second main plate portion 332 covers the intermediate block 40. Thus, the rotation of the intermediate block 40 with respect to the outer block 30 with the pin 51 of the fixing member 50 as the rotation axis is restricted by the second main plate portion 332. Therefore, when the band 1 is detached from the watch main body 110, it is possible to prevent the spring bar 20 from falling out of the outer block 30 and the intermediate block 40 due to the rotation of the intermediate block 40 with respect to the outer block 30.

[0095] In addition, the structure of the link member 10 in which the normal line distance R of the second main plate portion 332 from the second main plate portion 332 to the axial center of the pin 51 is shorter than the distance L from the axial center of the pin 51 to the end portion of the intermediate block 40 on the side of the decoration member 3 is an example of the rotation restriction structure of the present disclosure.

[0096] [Effects of the First Embodiment]

[0097] In such a first embodiment, the following effects can be obtained.

[0098] In the present embodiment, the band main body 2 having the plurality of decorative members 3 is connected to the link 10 by the fixing member 50. Also, the link 10 to which such a band main body 2 is connected can be easily connected to the watch main body 110 by the spring bar 20. Therefore, the band 1 of the present disclosure and other bands connected by a general spring bar can be used in common.

[0099] In addition, in the present embodiment, the band main body 2 can be detached from the link 10 as long as the fixing member 50 is detached. Therefore, maintenance of the decorative members 3 and the like can be easily performed.

[0100] In the present embodiment, the link 10 covers the connection ring 4.

[0101] Thus, when the band 1 is attached to the watch main body 110, the connection ring 4 can be hidden, and thus the design of the band 1 can be prevented from being degraded due to the connection ring 4 being exposed.

[0102] In the present embodiment, the spring bar 20 is disposed so as to pass through the first arm recess 311, the intermediate block insertion hole 42, the intermediate block recess 41, and the second arm insertion hole 322, and the operation portion 22 protrudes from the opening 47 of the intermediate block recess 41. In addition, the spring bar 20 is configured so that the operation portion 22 is movable in the axial direction O in a state of being housed in the outer block 30 and the intermediate block 40.

[0103] Thus, when the operation portion 22 is moved in the axial direction O, the spring bar 20 can be prevented from falling out of the outer block 30 and the intermediate block 40.

[0104] In addition, since the fall-out prevention structure of the spring bar 20 can be achieved without bending a part of the metal member, the outer block 30 and the intermediate block 40 that constitute the fall-out prevention structure can be made of a solid metal material. Therefore, a band 1 that is excellent in design and gives a high-class feeling, and in which the spring bar 20 having the operation portion 22 can be assembled, can be obtained.

[0105] In the present embodiment, when the operation portion 22 of the spring bar 20 is moved to the intermediate block recess 41 to detach the band 1 from the watch main body 110, the rotation of the intermediate block 40 with respect to the outer block 30 is restricted by the rotation restriction structure, and thus the spring bar 20 can be prevented from falling out of the outer block 30 and the intermediate block 40.

[0106] In the present embodiment, the normal line distance R of the second main plate portion 332 from the center of the axis of the fixing member 50 is made shorter than the distance L from the center of the axis of the fixing member 50 to the end portion of the intermediate block 40 on the side of the decorative member 3, thereby constituting the rotation restriction structure. Thus, even without additionally adding a member for restricting the rotation of the intermediate block 40, the rotation of the intermediate block 40 can be restricted by the second main plate portion 332, and thus the number of members can be reduced.

[0107] [Second Embodiment]

[0108] Next, the watchband 1A of the second embodiment of the present disclosure will be described based on the drawings.

[0109] The watchband 1A of the second embodiment differs from the above-described first embodiment in that the decorative members 3A are linked by the cords 5A in a manner of being arranged in three columns.

In the present embodiment, the intermediate block 40A is formed by cutting a part of the side opposite to the decorative member 3A. Also, the connection ring arrangement portion 60A is constituted by a gap of the cut portion of the intermediate block 40A.

[0123] [Effects of the second embodiment]

[0124] In such a second embodiment, the following effects can be obtained.

[0125] In the present embodiment, the decorative members 3A are linked by the wire 5A in a manner of being arranged in three columns. Therefore, it is possible to increase the design variations of the watchband 1A.

[0126] [Third embodiment]

[0127] Next, the watchband 1B of the third embodiment of the present disclosure will be described based on the drawings.

[0128] The watchband 1B of the third embodiment differs from the first and second embodiments described above in that the link member 10B is configured to have a terminal member 70B constituted by one member. Also, in the third embodiment, the same reference numerals are attached to the same or similar structures as those of the first and second embodiments, and the description thereof will be omitted.

[0129] Figure 11 、 Figure 12 is a perspective view showing the watchband 1B of the third embodiment. Also, in Figure 11 and Figure 12 , the watchband 1B is observed from different directions.

[0130] As Figure 11 , Figure 12 shown, the band 1B has, as with the aforementioned first embodiment, a band main body 2B configured by linking a plurality of decorative members 3B by a wire 5B, and a link member 10B linked to both end portions of the band main body 2B.

[0131] [BAND MAIN BODY]

[0132] The band main body 2B is, as with the aforementioned first embodiment, a main portion of the band 1B, and has a plurality of decorative members 3B, a connection ring 4B, and a wire 5B.

[0133] The decorative members 3B are, as with the aforementioned first embodiment, configured by pearls, and are linked by the wire 5B configured by a piano wire or the like. In the present embodiment, the decorative members 3B are linked by the wire 5B in a manner of being arranged in two columns.

[0134] Also, in the present embodiment, the connection ring 4B is disposed at the connection ring disposing portion 60B of the link member 10B, and is linked to the link member 10B by the fixing member 50. Thereby, the band main body 2B is linked to the link member 10B.

[0135] [LINK MEMBER]

[0136] The link member 10B has a terminal member 70B, a spring rod 80B, a fixing member 50, and a connection ring disposing portion 60B.

[0137] [TERMINAL MEMBER]

[0138] The terminal member 70B is a member for housing the spring rod 80B. In the present embodiment, the terminal member 70B is formed by one member by performing machining such as cutting on a solid metal material, and two portions on the side opposite to the decorative members 3B are cut away to be formed. Also, at the cut-away gaps of the terminal member 70B, the connection ring disposing portion 60B is configured.

[0139] Also, in the present embodiment, the side of the terminal member 70B opposite to the watch main body 110 is cut away in a curved shape in correspondence with the shape of the watch main body 110.

[0140] [SPRING ROD]

[0141] The spring rod 80B is a general spring rod configured by a shaft portion and a protruding portion, and is housed in the terminal member 70B. Also, the band 1B is linked to the watch main body 110 by inserting the protruding portion of the spring rod 80B into the hole portion 1121 provided at the holding piece portions 112A, 112B of the watch main body 110.

[0142] [EFFECT OF THE THIRD EMBODIMENT]

[0143] In such a third embodiment, the following effects can be obtained.

[0144] In the present embodiment, the link member 10B for linking the band 1B with the timepiece main body 110 has the terminal member 70B composed of one member. Therefore, the band main body 2B having a plurality of decorative members 3B can be linked with the link member 10B using such a terminal member 70B.

[0145] [Modified Example]

[0146] Further, the present disclosure is not limited to the aforementioned embodiments, and modifications, improvements, and the like within a range capable of achieving the object of the present disclosure are included in the present disclosure.

[0147] In the aforementioned embodiments, the link member 10, 10A, 10B and the band main body 2, 2A, 2B are linked by the fixing member 50 having the pin 51 and the C-shaped ring 52, but are not limited thereto. For example, the link member and the fixing member can be linked by a screw or the like.

[0148] In the first and second embodiments, the connection ring arrangement portion 60, 60A is configured by the gap between the outer block 30, 30A and the intermediate block 40, 40A, but is not limited thereto. For example, a notch portion can be formed on the outer side of the first and second arm portions of the outer block, and the connection ring arrangement portion can be configured using the notch portion. That is, the connection ring can be arranged in a manner of being sandwiched by the outer block, and then linked by the fixing member.

[0149] In the aforementioned embodiments, the link member 10, 10A, 10B is in a shape of covering the connection ring 4 entirely, but is not limited thereto. For example, only a part of the connection ring 4 can be covered, or the connection ring 4 can not be covered at all. For example, in the first and second embodiments, the main body portion 33, 33A of the outer block 30, 30A can be formed only by the first main body plate portion 331, and in the third embodiment, the connection ring arrangement portion 60B can be formed to be cut to the front side of the terminal member 70B.

[0150] In the aforementioned embodiments, the band main body 2, 2A, 2B is formed in a manner that the decorative members 3, 3A, 3B are arranged in two or three columns, but the decorative members can be arranged in one column or four or more columns.

[0151] Further, in the aforementioned embodiments, the connection ring 4, 4A, 4B is installed to each column of the decorative members 3, 3A, 3B, but is not limited thereto. For example, a plurality of columns of the decorative members can be installed on one connection ring.

[0152] In the respective embodiments, the outer block 30, 30A, the intermediate block 40, 40A, and the end piece 70B are formed of a solid metal material, but are not limited thereto. For example, these components can also be formed of a ceramic or a resin. In addition, at the end of the outer block 30, 30A, the intermediate block 40, 40A on the side of the band body 2, 2A, a curved portion 315, 326, a first curved portion 48, and a second curved portion 49 are formed to be cut in a spherical shape, but are not limited thereto. The curved portions can not be formed on the outer block 30, 30A, the intermediate block 40, 40A, and, for example, a spacer component different from the decorative component can be interposed between the connecting ring and the decorative component, thereby preventing the end piece including the outer block 30, 30A, the intermediate block 40, 40A from directly contacting the decorative component.

[0153] In the first and second embodiments, the second arm recess 321, 321A is provided in the second arm portion 32, 32A, but is not limited thereto. For example, a case where the second arm recess is not provided in the second arm portion is also included in the present disclosure. In this case, the operation portion of the spring rod can be limited in the movable range by the intermediate block recess and the second arm portion.

[0154] In the respective embodiments, the band 1, 1A, 1B of the timepiece 100 is exemplified, but is not limited thereto. For example, the present disclosure can be applied to an arm-mounted device such as a pulse meter and a band mounted on the arm-mounted device.

[0155] [Summary of the Present Disclosure]

[0156] The band of the present disclosure has a spring rod having a shaft component, a band body having a plurality of decorative components coupled, and a connecting ring coupled to the end portions of the plurality of decorative components, a coupling piece having a spring rod insertion hole into which the spring rod is inserted, a fixing component insertion hole, and a connecting ring arrangement portion in which the connecting ring is arranged, the coupling piece being capable of being coupled to a band body of a timepiece using the spring rod, and a fixing component inserted into the fixing component insertion hole and the connecting ring, thereby connecting the band body and the coupling piece.

[0157] Thus, the band body having a plurality of decorative components is connected to the coupling piece by the fixing component. Further, the coupling piece to which such a band body is connected can be easily connected to the band body of the timepiece or the like by the spring rod. Therefore, the band of the present disclosure and another band coupled by a general spring rod can be used together.

[0158] In addition, the band body can be detached from the coupling piece as long as the fixing component is detached. Therefore, maintenance of the decorative component or the like can be easily performed.

[0159] In the watchband of the present disclosure, the link member can also have a cover portion covering at least a portion of the connection ring.

[0160] Thus, at least a portion of the connection ring can be covered, and thus, the design of the watchband can be prevented from being degraded due to the exposure of the connection ring.

[0161] In the watchband of the present disclosure, the link member can also have an outer block having a first arm portion, a second arm portion, and a main body portion connecting the first arm portion and the second arm portion, and an intermediate block disposed between the first arm portion and the second arm portion, the connection ring disposed portion being formed between the outer block and the intermediate block, a first recess portion being provided in the first arm portion along the axial direction of the shaft member, a first insertion hole constituting the spring rod insertion hole being provided in the second arm portion along the axial direction, a second insertion hole constituting the spring rod insertion hole being provided in the intermediate block along the axial direction, a second recess portion being provided in the intermediate block along the axial direction and communicating with the second insertion hole, the first recess portion, the second insertion hole, the second recess portion, and the first insertion hole being disposed in this order along the axial direction, the spring rod having an operation portion and a protruding member, the spring rod being inserted into the first recess portion, the second insertion hole, the second recess portion, and the first insertion hole, and the operation portion being disposed to protrude from the opening of the second recess portion, the operation portion being configured to be movable in the axial direction in this state.

[0162] Thus, in the case where the operation portion is moved in the axial direction, the spring rod can be prevented from being detached from the outer block and the intermediate block.

[0163] In addition, since the spring rod detachment prevention structure can be achieved without bending a portion of the metal member, the outer block and the intermediate block constituting the detachment prevention structure can be made of a solid metal material. Thus, a watchband having excellent design and a high-class appearance can be obtained.

[0164] In the watchband of the present disclosure, the link member can also have a rotation restriction structure that restricts the intermediate block from rotating relative to the outer block with the fixing member as a rotation axis.

[0165] Thus, when the watchband is detached from a timepiece main body or the like, the rotation of the intermediate block relative to the outer block is restricted by the rotation restriction structure, and thus, the spring rod can be prevented from being detached from the outer block and the intermediate block.

[0166] In the watchband of the present disclosure, it can also be that the main body portion has a first main body plate portion and a second main body plate portion extending in a direction intersecting the first main body plate portion and covering the intermediate block, and the rotation restriction structure is configured such that the normal line distance of the second main body plate portion from the second main body plate portion to the center of the fixed member is shorter than the distance from the center of the fixed member to the end portion of the intermediate block on the side of the decorative member.

[0167] Thus, even without additionally adding a component for restricting the rotation of the intermediate block, the rotation of the intermediate block can be restricted by the second main body plate portion, and thus the number of components can be reduced.

[0168] The watch of the present disclosure has the watchband.
