Description

Technical Field

[0001] This invention relates to watch straps and clocks. Background Technology

[0002] Patent Document 1 discloses a watch strap that connects to a watch case. In Patent Document 1, the watch strap and the watch case can be easily connected by operating the terminal of a spring bar mounted on the watch strap.

[0003] Patent Document 1: Japanese Patent Application Publication No. 2004-187978

[0004] In Patent Document 1, a spring bar is inserted into a cylindrical portion located at the end of the watch strap, and then the spring bar is installed on the watch strap by bending a stopper located in the cylindrical portion. This prevents the spring bar from detaching from the watch strap by interfering with the stopper through the operating terminal of the spring bar.

[0005] However, if such a spring bar mounting structure is adopted, a portion of the component at the end of the watchband needs to be configured to be flexible. Therefore, there is a problem that it is difficult to manufacture such a spring bar anti-slip structure without bending the component, for example, it is difficult to achieve this by machining pure metal materials.

[0006] If the components at the end of the watch band are manufactured by processing pure metal, the appearance is excellent and a high-end feel can be achieved. Therefore, it is desirable to manufacture watch band components that can be made of pure metal and can be assembled with spring bars that have operating terminals. Summary of the Invention

Detailed Implementation

[0033] [First Implementation]

[0034] In the following description, a clock 100 according to the first embodiment of the present disclosure is illustrated with reference to the accompanying drawings.

[0035] Figure 1 This is a perspective view showing the main parts of the clock 100 according to the first embodiment.

[0036] like Figure 1 As shown, the clock 100 has a clock body 110 and a watch strap 1.

[0037] The main body of the clock 110 has a case 111 and lugs 112.

[0038] The housing 111 includes a main body 113, a glass edge 114, a cover glass 115, and a back cover 116.

[0039] The main body 113 is a cylindrical component made of metal, which houses a dial, movement, etc. (not shown in the diagram) inside.

[0040] The glass rim 114 is a ring-shaped component made of metal, disposed on the upper part of the main body 113. The cover glass 115 is disposed to cover the opening on the upper side of the main body 113, is fixed by the glass rim 114, and covers the dial (not shown). The back cover 116 is a component made of metal, disposed to cover the opening on the lower side of the main body 113.

[0041] Lugs 112 are respectively located at the 6 o'clock and 12 o'clock positions on the main stem 113. Furthermore, each lug 112 has a pair of retaining plates 112A and 112B protruding from the side of the main stem 113. Each retaining plate 112A and 112B has a hole 1121 for inserting the protruding parts 23 and 24 of the spring bar 20, described later.

[0042] [Watch Strap]

[0043] Figure 2 This is a 3D view showing watch band 1. Figure 3 , Figure 4 This is an exploded perspective view showing the connector 10. Additionally, in Figure 3 and Figure 4The connector 10 is viewed from different directions. Furthermore, the connector 10 is a so-called end piece used to attach the watch strap 1 to the watch body 110.

[0044] like Figures 1-4 As shown, the watch strap 1 has a watch strap body 3 composed of multiple metal blocks 2, and connecting members 10 that are connected to both ends of the watch strap body 3 and mounted on a pair of retaining plates 112A and 112B. Additionally, in Figure 1 The diagram only shows the connecting member 10 of the retaining plates 112A and 112B installed at the 6 o'clock position on the clock 100.

[0045] [Link]

[0046] The connecting member 10 has a spring rod 20, an outer block 30, a middle block 40, and a fixing component 50.

[0047] [Spring Rod]

[0048] The spring bar 20 is a component used to detachably connect the connecting member 10 to a pair of retaining plates 112A, 112B. In this embodiment, the spring bar 20 has a shaft component 21, an operating part 22, a first protruding part 23, a second protruding part 24, and a spring component 25. Furthermore, the spring bar 20 is inserted through the first arm recess 311, the middle block through insertion hole 42, the middle block recess 41, the second arm recess 321, and the second arm through insertion hole 322, as described later.

[0049] The shaft component 21 is made of metal and is cylindrical, with openings at both ends. Furthermore, an elongated hole 211 is provided on the outer circumferential surface of the shaft component 21. Additionally, the shaft component 21 is configured such that its length is approximately equal to the width of the outer block 30, that is, the length from one side 313 of the first arm 31 (described later) to the other side 325 of the second arm 32.

[0050] The operating part 22 protrudes from the first protruding member 23 in a direction perpendicular to the axial direction O of the shaft member 21, and protrudes from the elongated hole 211 of the shaft member 21. In this embodiment, the operating part 22 is integrally provided with the first protruding member 23. Furthermore, the operating part 22 is configured to be movable within the elongated hole 211 along the axial direction O. As a result, since the first protruding member 23 integrally provided with the operating part 22 can be moved along the axial direction O, the connecting member 10 can be attached to and detached from the lug 112 of the watch 100. In other words, the elongated hole 211 is provided to a length such that the first protruding member 23 disengages from the hole 1121 of the lug 112 when the operating part 22 is moved along the axial direction O. In addition, the axial direction O is a direction perpendicular to the direction in which the watch strap body 3 of the watch strap 1 extends.

[0051] Furthermore, when the spring bar 20 is housed in the outer block 30 and the middle block 40, the operating part 22 protrudes from the opening 47 of the middle block recess 41 (described later). Thus, with the spring bar 20 housed in the outer block 30 and the middle block 40, the operating part 22 can move along the axial direction O of the shaft member 21 within the middle block recess 41 and the second arm recess 321.

[0052] The base end of the major diameter of the first protruding member 23 is housed inside the shaft member 21. Furthermore, the front end of the minor diameter protrudes axially from an opening provided at one end of the shaft member 21.

[0053] Additionally, the first protruding member 23 is subjected to force by the spring member 25, causing its front end to protrude along the axial direction O of the shaft member 21. At this time, the first protruding member 23 is in a state where its large-diameter base end is engaged with the end of the shaft member 21.

[0054] Furthermore, the first protruding member 23 is configured such that, with the spring rod 20 housed in the outer block 30 and the middle block 40, its front end protrudes from the outer block 30 along the axial direction O.

[0055] The base end of the second protruding member 24 with a large diameter is housed inside the shaft member 21. Furthermore, the front end of the minor diameter is configured to protrude axially from an opening provided at the other end of the shaft member 21.

[0056] 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.

[0057] Furthermore, the second protruding member 24 is configured such that its front end protrudes from the outer block 30 when the spring rod 20 is housed in the outer block 30 and the middle block 40. Additionally, the first protruding member 23 and the second protruding member 24 are examples of protruding members of this disclosure.

[0058] 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, applying force to the first protruding component 23 and the second protruding component 24 respectively, so that they protrude from the shaft component 21 along the axial direction O.

[0065] The second arm portion 32 is configured to extend from the other end 332 of the torso 33 in a direction perpendicular to the length direction of the torso 33. That is, the first arm portion 31 and the second arm portion 32 extend parallel to each other. In addition, in this embodiment, the first arm portion 31 and the second arm portion 32 extend from the torso 33 toward the side where the block 2 is disposed.

[0066] The second arm portion 32 is provided with a second arm recess 321, a second arm through insertion hole 322 and a second arm fixing hole 323.

[0067] The second arm recess 321 is a recess for mounting the shaft member 21 of the spring bar 20, and is provided along the axial direction O of the shaft member 21. In this embodiment, the second arm recess 321 extends from one side 324 of the second arm 32 to near the center of the second arm 32. Furthermore, the second arm recess 321 is provided at a position corresponding to the center block recess 41 of the center block 40 described later, i.e., adjacent to the center block recess 41. Moreover, the second arm recess 321 is configured to open towards the back side of the watch 100 when the watch strap 1 is mounted on the watch 100. The second arm recess 321 is an example of the third recess of this disclosure.

[0068] The second arm through insertion hole 322 is a hole through which the shaft component 21 of the spring rod 20 is inserted, and is provided along the axial direction O of the shaft component 21. In this embodiment, the second arm through insertion hole 322 communicates with the second arm recess 321, and extends through the second arm portion 32 to reach the other side 325 of the second arm portion 32. The second arm through insertion hole 322 is an example of the first through insertion hole of this disclosure.

[0069] The second arm fixing hole 323 is a hole for inserting the fixing member 50, and is provided along the axial direction of the pin 51 of the fixing member 50, which will be described later. In this embodiment, the second arm fixing hole 323 passes through the second arm portion 32 from one side 324 to the other side 325.

[0070] The torso 33 connects the first arm 31 and the second arm 32. In this embodiment, the torso 33 is formed in the shape of a rod and is arranged such that its length direction is parallel to the axial direction O of the shaft member 21 of the spring rod 20. In addition, as described above, the first arm 31 of the torso 33 extends from one end 331 and the second arm 32 extends from the other end 332.

[0071] [Middle Block]

[0072] The middle block 40 is a component used to connect with the outer block 30 and house the spring rod 20. It is positioned between the first arm 31 and the second arm 32 by means of the fixing component 50. In this embodiment, the middle block 40 is formed by machining pure metal material, such as cutting.

[0073] The middle block 40 is provided with a middle block recess 41, a middle block through insertion hole 42, a middle block fixing hole 43 and a middle block connecting hole 44.

[0074] The center block recess 41 is a recess for mounting the shaft member 21 of the spring bar 20, and is provided along the axial direction O of the shaft member 21. In this embodiment, the center block recess 41 extends from near the center of the center block 40 to the side surface 46 of the center block 40. Furthermore, the center block recess 41 is located at a position corresponding to the second arm through insertion hole 322 of the second arm portion 32, and communicates with the center block through insertion hole 42. Moreover, the center block recess 41 is configured to open towards the back side of the watch 100 when the watch strap 1 is mounted on the watch 100. Furthermore, the center block recess 41 is an example of the second recess of this disclosure.

[0075] The through-hole 42 is a hole through which the shaft component 21 of the spring rod 20 is inserted, and is provided along the axial direction O of the shaft component 21. In this embodiment, the through-hole 42 is provided at a position corresponding to the first arm recess 311, that is, adjacent to the first arm recess 311. In addition, the through-hole 42 passes through the side 45 of the middle block 40 to reach the middle block recess 41.

[0076] Thus, in this embodiment, along the axial direction O, the first arm recess 311, the middle block through insertion hole 42, the middle block recess 41, the second arm recess 321, and the second arm through insertion hole 322 are arranged in that order. Furthermore, the middle block through insertion hole 42 is an example of the second through insertion hole of this disclosure.

[0077] The middle block fixing hole 43 is a hole for inserting the fixing member 50. It is provided along the axial direction O of the pin 51 of the fixing member 50 (described later), and passes through the middle block 40 from one side 45 to the other side 46. In this embodiment, the middle block fixing hole 43 has a large diameter portion 431 and a small diameter portion 432 with a diameter smaller than the large diameter portion 431. Furthermore, the C-shaped ring 52 of the fixing member 50 (described later) is disposed in the large diameter portion 431.

[0078] The middle block connecting hole 44 is a hole through which a connecting component (not shown in the diagram) connecting the middle block 40 and block 2 is inserted. In this embodiment, the middle block connecting hole 44 passes through the middle block 40 from one side 45 to the other side 46.

[0079] [Fixed components]

[0080] The fixing component 50 is used to fix the middle block 40 between the first arm 31 and the second arm 32 of the outer block 30. In this embodiment, the fixing component 50 has a pin 51 and a C-ring 52.

[0081] Pin 51 is made of metal and is inserted into the first arm fixing hole 312, the middle block fixing hole 43, and the second arm fixing hole 323. In addition, pin 51 is configured such that its outer diameter is approximately equal to the small diameter portion 432 of the first arm fixing hole 312 and the middle block fixing hole 43, and the inner diameter of the second arm fixing hole 323.

[0082] The C-ring 52 is made of a metal such as stainless steel and, as described above, is disposed in the large-diameter portion 431 of the middle block fixing hole 43. Furthermore, a pin 51 is inserted into the inside of the C-ring 52.

[0083] Next, the assembly method of the connector 10 will be explained.

[0084] Figures 5-7 This is a perspective view showing the assembly method of the connector 10.

[0085] First, such as Figure 5 As shown, the shaft component 21 of the spring bar 20 is inserted through the through insertion hole 42 of the middle block 40. Thus, the spring bar 20 is positioned in the middle block recess 41 and the through insertion hole 42 of the middle block 40. At this time, the spring bar 20 is positioned such that the operating part 22 protrudes from the opening 47 of the middle block recess 41.

[0086] Next, as Figure 6 As shown, the operating part 22 of the spring bar 20 is moved along the axial direction O, so that the operating part 22 engages with the middle block 40. Furthermore, the C-ring 52 is positioned in the large-diameter portion 431 of the middle block fixing hole 43.

[0087] In this state, the middle block 40 is positioned between the first arm 31 and the second arm 32 of the outer block 30. At this time, the shaft component 21 of the spring rod 20 is positioned in the first arm recess 311 of the first arm 31.

[0088] Additionally, at this time, the first protruding member 23 is disposed in the second arm recess 321. That is, the middle block recess 41 is formed such that, when the operating part 22 is engaged with the middle block 40, the front end of the first protruding member 23 protrudes from the side 46 of the middle block 40.

[0089] Therefore, with the first protruding member 23 protruding from the side 46 of the middle block 40, the first protruding member 23 does not interfere with the second arm 32, so the middle block 40 can be positioned between the first arm 31 and the second arm 32.

[0090] Next, as Figure 7 As shown, the operating part 22 of the spring bar 20 is moved along the axial direction O, causing the shaft member 21 to pass through and be inserted into the second arm through insertion hole 322 of the second arm 32. Therefore, for example, if the operating part 22 is moved towards the first arm 31, the operating part 22 interferes with the middle block 40 after a predetermined amount of movement. Furthermore, when the shaft member 21 is moved towards the second arm 32, the operating part 22 interferes with the second arm 32 after a predetermined amount of movement. Therefore, it is possible to prevent the spring bar 20 from detaching from the outer block 30 and the middle block 40 when the operating part 22 is moved along the axial direction O.

[0091] Finally, pin 51 is inserted into the first arm fixing hole 312, the middle block fixing hole 43, and the second arm fixing hole 323. Pin 51 is then pressed into the inside of the C-ring 52 located in the large-diameter portion 431 of the middle block fixing hole 43, causing the C-ring 52 to deform outwards. As a result, the C-ring 52 engages with the large-diameter portion 431, preventing pin 51 from falling out of the first arm fixing hole 312, the middle block fixing hole 43, and the second arm fixing hole 323. Therefore, the middle block 40 is fixed to the outer block 30 using the fixing member 50.

[0092] [Effects of the First Embodiment]

[0093] In this first embodiment, the following effects can be obtained.

[0094] In this embodiment, the spring bar 20 is arranged such that it passes through the first arm recess 311, the middle block through insertion hole 42, the middle block recess 41, and the second arm through insertion hole 322, and the operating part 22 protrudes from the opening 47 of the middle block recess 41. Furthermore, the spring bar 20 is configured such that, when the spring bar 20 is housed in the outer block 30 and the middle block 40, the operating part 22 can move axially along O.

[0095] Therefore, it is possible to prevent the spring bar 20 from falling off the outer block 30 and the middle block 40 when the operating part 22 moves along the axial direction O.

[0096] Furthermore, since the anti-slip structure of the spring bar 20 can be achieved without bending a part of the metal component, the outer block 30 and the middle block 40 constituting the anti-slip structure can be made of pure metal material. Therefore, a watch strap 1 with an assembleable spring bar 20 having an operating part 22 and an excellent appearance can be obtained, resulting in a high-end feel.

[0097] In this embodiment, since a second arm recess 321 is provided in the second arm portion 32, the middle block 40 can be positioned between the first arm portion 31 and the second arm portion 32 while the first protruding member 23 protrudes from the middle block 40. Therefore, the assembly of the connecting member 10 can be facilitated.

[0098] In this embodiment, the middle block 40 is fixed between the first arm 31 and the second arm 32 by a C-ring 52 and a pin 51. This allows the middle block 40 to be fixed to the outer block 30 with a simple fixing structure. Furthermore, by removing the pin 51, the middle block 40 can be removed from the outer block 30, thus allowing for replacement of the middle block 40, for example, if it becomes damaged.

[0131] Next, the assembly method of connector 10A will be explained.

[0132] Figures 12-14 This is a perspective view showing the assembly method of connector 10A.

[0133] First, such as Figure 12 As shown, the shaft component 21 of the spring bar 20 is inserted through the first intermediate block through insertion hole 411A of the first intermediate block component 410A. Then, the operating part 22 is moved along the axial direction O, so that the operating part 22 engages with the first intermediate block component 410A. Next, a C-ring 52 is disposed in the first intermediate block fixing hole 412A.

[0134] In this state, the first middle block member 410A is arranged adjacent to the inner side of the first arm portion 31A of the outer block 30A, so that the shaft member 21 engages with the first arm recess 311A.

[0135] Next, as Figure 13 As shown, the operating part 22 is moved along the axial direction O, so that the shaft member 21 is inserted through the second arm through insertion hole 322A of the second arm part 32A. Then, with the shaft member 21 as the rotation axis, the first middle block member 410A is rotated, so that the first middle block engaging recess 413A engages with the body 33A of the outer block 30A.

[0136] Next, the second middle block component 420A and the third middle block component 430A are positioned between the first middle block component 410A and the second arm portion 32A, and are engaged with the shaft component 21 of the spring rod 20. Specifically, the second middle block recess 421A of the second middle block component 420A is engaged with the shaft component 21, and the third middle block recess 431A of the third middle block component 430A is engaged with the shaft component 21.

[0137] Next, as Figure 14 As shown, the second middle block component 420A and the third middle block component 430A are rotated with the shaft component 21 as the rotation center. As a result, the second middle block engaging portion 422A of the second middle block component 420A engages with the body 33A of the outer block 30A, and the third middle block engaging recess 43A of the third middle block component 430A engages with the body 33A.

[0138] Then, pin 51 is inserted into the first arm fixing hole 312A, the first middle block fixing hole 412A, the second middle block fixing hole, the third middle block fixing hole 432A, and the second arm fixing hole 323A. Thus, the middle block 40A, configured to have a first middle block component 410A, a second middle block component 420A, and a third middle block component 430A, is fixed between the first arm portion 31A and the second arm portion 32A of the outer block 30A.

[0141] In this embodiment, the middle block 40A is configured to have a plurality of middle block components 410A, 420A, and 430A.

[0142] This allows for greater design flexibility in the central block 40A that constitutes the watch band 1A. Consequently, the appearance of the watch band 1A can be further improved.

[0143] In this embodiment, the middle block 40A is provided with engaging recesses 413A and 433A that engage with the torso 33A.

[0144] Therefore, by engaging the engagement recesses 413A and 433A with the torso 33A, the middle block 40A is fixed to the outer block 30A, thus enabling more reliable fixation of the middle block 40A relative to the outer block 30A. Furthermore, by engaging the engagement recesses 413A and 433A with the torso 33A, the middle block fixing holes 412A and 432A can be positioned, thus facilitating the assembly of the connecting member 10A.

[0201] In this embodiment, similar to the first embodiment described above, the middle block 40D is composed of a single component. Furthermore, the middle block 40D is disposed between the first outer block component 310D and the second outer block component 320D.

[0202] In addition, the middle block 40D is provided with a middle block recess 41D, a middle block through insertion hole 42D, a middle block fixing hole 43D, and a middle block connecting hole 44D.

[0203] The central recess 41D is a recess for mounting the shaft component 21 of the spring bar 20, and is provided along the axial direction O of the shaft component 21. In this embodiment, the central recess 41D is provided at a position corresponding to the second outer block through-hole 321D of the second outer block component 320D, that is, adjacent to the second outer block through-hole 321D, and communicates with the central recess 42D. Furthermore, the operating part 22 of the spring bar 20 is arranged to protrude from the opening 47D of the central recess 41D.

[0204] The through-hole 42D of the middle block is a hole through which the shaft component 21 of the spring rod 20 is inserted, and is provided along the axial direction O of the shaft component 21. In this embodiment, the through-hole 42D of the middle block is provided at a position corresponding to the through-hole 311D of the first outer block component 310D, that is, it is provided adjacent to the through-hole 311D of the first outer block component 310D.

[0205] Thus, in this embodiment, along the axial direction O, the first outer block through insertion hole 311D, the middle block through insertion hole 42D, the middle block recess 41D, and the second outer block through insertion hole 321D are arranged in that order.

[0206] The middle block fixing hole 43D is a hole for inserting the fixing component 50, and it is set along the axial direction O.

[0207] The connecting hole 44D of the middle block is a hole through which the connecting component, which is not shown in the figure of the middle block 40D and the block 2D, is inserted.

[0208] [Effects of the 5th Embodiment]

[0209] In this fifth embodiment, the following effects can be obtained.

[0210] In this embodiment, the outer block 30D is configured to have a first outer block member 310D and a second outer block member 320D. Furthermore, the first outer block member 310D and the second outer block member 320D do not have the first arm, second arm, and torso as described in the first to fourth embodiments.

[0211] This increases the design freedom of the outer block 30D that constitutes the watch band 1D, thus allowing for greater design variation. Consequently, the appearance of the watch band 1D can be further improved.

[0212] [Variation Example]

[0213] Furthermore, this disclosure is not limited to the above-described embodiments, and variations and improvements within the scope of achieving the purpose of this disclosure are included in this disclosure.

[0214] In the above embodiments, the middle blocks 40, 40A, 40B, 40C, and 40D are fixed to the outer blocks 30, 30A, 30B, 30C, and 30D by fixing components 50 and 50D, but are not limited thereto. For example, the middle blocks can also be fixed to the outer blocks by bonding, welding, screws, etc.

[0215] In the above embodiments, the blocks 2, 2A, 2B, 2D, outer blocks 30, 30A, 30B, 30C, 30D, and middle blocks 40, 40A, 40B, 40C, 40D constituting the watchbands 1A, 1B, 1D are formed of pure metal materials, but are not limited thereto. For example, these components may also be formed of ceramic or resin.

[0216] In the first, second, and fourth embodiments described above, second arm recesses 321, 321A, and 321C are provided in the second arm portions 32, 32A, and 32C, but this is not a limitation. For example, the case in which no second arm recess is provided in the second arm portion is also included in this disclosure. In this case, the movable range of the operating part of the spring rod can also be limited by the middle block recess and the second arm portion.

[0217] In the first to fourth embodiments described above, middle block recesses (second recesses) 41, 41A, and 431B are provided in the middle blocks 40, 40A, 40B, and 40C, but this is not a limitation. For example, if the width of the second arm portion is greater than the width of the middle block in the axial direction of the shaft member, the middle block recess, i.e., the recess protruding from the operating part of the spring bar, may not be provided in the middle block. In this case, the shaft member holding the spring bar can be held by the middle block through insertion hole of the middle block, and the operating part of the spring bar can be restricted by the second arm recess provided in the second arm portion and the side of the middle block.

[0218] Furthermore, in the fifth embodiment described above, a recess 41D is provided in the middle block 40D, but this is not a limitation. For example, a recess protruding from the operating part of the spring bar may also be provided in the second outer block member. In this case, the shaft member of the spring bar may be held by the middle block through insertion hole of the middle block, and the operating part of the spring bar may be restricted by the second outer block recess provided in the second outer block member and the side of the middle block.

[0219] This configuration achieves the same effect as the above-described implementation method.

[0220] In the above embodiments, watch straps 1, 1A, 1B, and 1D of the watch 100 are illustrated, but the invention is not limited thereto. For example, this disclosure can be applied to wrist devices such as pulse meters and watch straps mounted on such wrist devices.

[0221] [Summary of this disclosure]

[0222] The watch strap disclosed herein includes: a spring bar having a shaft member, an operating part, and a protruding part; an outer block having a first arm, a second arm, and a body connecting the first arm and the second arm; and a middle block disposed between the first arm and the second arm, wherein the first arm has a first recess along the axial direction of the shaft member, the second arm has a first through insertion hole along the axial direction, the middle block has a second through insertion hole along the axial direction, and a second recess communicating with the second through insertion hole is disposed along the axial direction, wherein the first recess, the second through insertion hole, the second recess, and the first through insertion hole are arranged in the order of the axial direction, and the spring bar is configured to be inserted through the first recess, the second through insertion hole, the second recess, and the first through insertion hole and disposed such that the operating part protrudes from the opening of the second recess, in which state the operating part is movable in the axial direction.

[0223] Therefore, when the operating part moves axially, it is possible to prevent the spring bar from falling off the outer block and the middle block.

[0224] Furthermore, since the spring bar's anti-slip structure can be achieved without bending any part of the metal components, the outer and middle blocks constituting the anti-slip structure can be made from pure metal materials. Therefore, a watch strap with excellent appearance and a high-end feel can be obtained.

[0225] In the watch strap disclosed herein, the third recess may be continuously arranged along the axial direction with the second recess in the second arm portion.

[0226] Therefore, since the middle block can be easily positioned between the first arm and the second arm, the watch strap can be easily assembled.

[0227] In the watch strap disclosed herein, the middle block may be fixed between the first arm and the second arm by a C-ring and a pin.

[0228] Therefore, the middle block can be fixed to the outer block with a simple structure. In addition, if the pin is pulled out, the middle block can be removed from the outer block, so that the middle block can be replaced, for example, if the middle block is damaged.

[0229] In the watch strap disclosed herein, the center block may be configured to have multiple center block components.

[0230] This allows for greater variation in the design of the central section that makes up the watch band. Consequently, it further enhances the watch band's appearance.

[0231] In the watch strap disclosed herein, the middle block may be provided with an engaging recess that engages with the torso.

[0232] Therefore, by engaging the locking recess with the torso, the middle block is fixed to the outer block, thus enabling more reliable fixation of the middle block relative to the outer block.

[0233] The watch strap disclosed herein includes: a spring bar having a shaft member, an operating part, and a protruding part; an outer block having a first outer block member and a second outer block member; and a middle block disposed between the first outer block member and the second outer block member. The first outer block member has a first outer block through-hole along the axial direction of the shaft member, the second outer block member has a second outer block through-hole along the axial direction, the middle block has a middle block through-hole along the axial direction, and a middle block recess communicating with the middle block through-hole is provided along the axial direction. Along the axial direction, the spring bar is arranged in the order of the first outer block through-hole, the middle block through-hole, the middle block recess, and the second outer block through-hole. The spring bar is configured to be inserted through the first outer block through-hole, the middle block through-hole, the middle block recess, and the second outer block through-hole, and the operating part protrudes from the opening of the middle block recess. In this state, the operating part is movable along the axial direction.

[0234] The watch disclosed herein has the aforementioned strap.
