Detailed Embodiment

[0035] With reference to Figures 1 to 8 , an embodiment of the watch band and the watch of the present invention will be described.

[0036] In addition, in the following-described embodiment, the case where the watch band is provided for a watch (hereinafter referred to as "watch 100") worn on the wrist will be described as an example. Further, in the following embodiment, various technically preferable limitations are added for implementing the present invention, but the scope of the present invention is not limited to the following embodiment and the illustrated example.

[0037] 〔Structure〕

[0038] Figure 1 It is a schematic top view of an example of a watch equipped with the watch band of the present embodiment as viewed from the back side. In addition, Figure 1 it is shown from the side (hereinafter referred to as "back") that comes into contact with the skin when the watch equipped with the watch band is worn on the wrist. In addition, the Figure 1 side surface (the surface on the visual confirmation side of the watch) that is not shown in is defined as the "surface" of the watch band 2.

[0039] In addition, hereinafter, the extending direction of the watch band 2 is defined as the long side direction of the watch band 2 (in Figure 1The middle is the "long side direction L"), and the short side direction of the watch band 2 orthogonal to this long side direction L is set as the width direction of the watch band 2 (in Figure 1 it is the "width direction W").

[0040] As Figure 1 shown, the clock 100 of the present embodiment includes a clock main body 1 and a watch band 2 connected to a housing of the clock main body 1 (hereinafter referred to as "main body housing 10").

[0041] First, the main body housing 10 constituting the clock main body 100 is formed in a hollow short column shape.

[0042] The main body housing 10 is formed of a hard material such as various metals such as titanium and stainless steel (SUS). In addition, the material forming the main body housing 10 is not limited to the materials exemplified herein. For example, it may also be a hard synthetic resin such as super engineering plastics such as polyarylate (PAR) and engineering plastics such as polyoxymethylene (POM).

[0043] Although not shown, a clock module is accommodated in the hollow portion inside the main body housing 10. The clock module includes, for example: a clock movement, which includes a digital display mechanism having an analog display mechanism for moving the hands and a liquid crystal display unit; and various component parts required for clock functions such as a circuit unit for controlling the driving of the above mechanisms. In addition, a display unit (not shown) for displaying time and various information is provided on the surface of the main body housing 10. In addition, operation parts such as a crown and buttons (not shown) are provided on the side part of the main body housing 10.

[0044] In addition, Figure 1 is a schematic diagram showing the clock main body 1, and does not accurately represent the specific shape, structure, etc.

[0045] As Figure 1 shown, on the outer side of the main body housing 10 and at positions corresponding to the 6 o'clock side and the 12 o'clock side of the analog clock, there are respectively provided watch band mounting portions 12 for connecting the watch band 2 to the main body housing 10.

[0046] In the illustrated example, the watch band mounting portion 12 has a shape in which lugs (lugs) 121 project from both sides in the width direction of the main body housing 10, and a second end portion 26 of the watch band 2 described later is fitted between the lugs 121. In addition, the shape of the watch band mounting portion 12 is not limited to the illustrated example. The watch band 2 is provided with a second end portion 26 formed in a shape corresponding to the shape of the watch band mounting portion 12.

[0047] As Figure 1 shown, the watch band 2 includes a short watch band 21 (female watch band) and a long watch band 22 (tip watch band).

[0048] The short strap 21 (female strap) is installed at the strap installation part 12 on the 12 o'clock side of the analog clock. One end side of the short strap 21 (female strap) becomes the first end part 25 where the mounting buckle 23 and the convex rod 24 are located, and the other end side becomes the second end part 26 which is the installation part mounted on the main body case 10.

[0049] In the embodiment, the buckle 23 and the convex rod 24 are formed of various resins such as plastics, for example. In addition, the materials forming the buckle 23 and the convex rod 24 are not limited thereto. For example, they can be formed of various metals, or can be formed of ceramics or the like. Additionally, the buckle 23 and the convex rod 24 can also be formed of materials with different materials, colors, textures, etc.

[0050] The buckle 23 is a frame-shaped member having a pair of frame legs 231, and a connection hole 232 is formed inside the frame legs 231 (the side facing the strap main body 20 when installed on the strap main body 20). The connection hole 232 is provided at a position corresponding to the through hole 251 (described later) of the first end part 25 of the strap main body 20. The connection hole 232 can be a recess that is at least open on the side facing the through hole 251 and does not penetrate even if it penetrates to the other side.

[0051] In addition, the convex rod 24 is installed at the first end part 25 of the strap main body 20 and at approximately the central part in the width direction W. A through hole (not shown) for inserting the connection member 5 (connection member 5a) described later is provided at the part of the convex rod 24 installed at the first end part 25 of the strap main body 20.

[0052] On the long strap 22 (tip strap), at positions corresponding to the convex rod 24 in the width direction W, small holes 221 for inserting the convex rod 24 are formed in multiple rows along the long side direction L of the strap 2. In addition, the installation side of the long strap 22 (tip strap) toward the main body case 10 becomes the installation part, that is, the second end part 26.

[0053] Figure 2 It is a top view of the short strap (female strap) viewed from the back side. Figure 3 It is from Figure 2 The side view of the short strap (female strap) viewed in the direction of arrow III in. Although not shown, the structure of the installation side of the long strap 22 (tip strap) toward the main body case 10, that is, the second end part 26, is the same as that of the second end part 26 of the short strap 21 (female strap).

[0054] As Figure 1 and Figure 2As shown, the watch band 2 of the present embodiment includes a watch band main body 20 and a connecting member 5 installed at the end of the watch band main body 20. The watch band main body 20 is formed into a long strip shape by various soft synthetic resins such as polyurethane resin, silicone resin, and fluororubber (a resin having rubber elasticity composed of fluororesin), and at least a part thereof has flexibility. In addition, the material forming the watch band main body 20 may be any flexible and soft material, and is not limited to the materials exemplified herein.

[0055] Inside the ends of the watch band main body 20, that is, the first end 25 on one end side of the watch band main body 20 and the second end 26 on the other end side, through holes 251 and 261 penetrating in the width direction W are respectively formed.

[0056] The connecting member 5 is, for example, formed of SUS (stainless steel) or the like, is axially shaped to penetrate the watch band main body 20 in the width direction W, and is connected to a connection object when protruding at the front end.

[0057] The connecting member 5 may be provided on at least one of the one end side and the other end side of the watch band 2. In the present embodiment, the connecting member 5 is provided at the first end 25 on one end side and the second end 26 on the other end side of the watch band main body 20 in the short watch band 21 (female watch band), and at the second end 26 on the mounting side to the main body case 10 in the long watch band 22 (tip watch band).

[0058] That is, as described above, the through hole 251 penetrating in the width direction W of the watch band 2 is provided at the first end 25, and the through hole 261 penetrating in the width direction W of the watch band 2 is provided at the second end 26. Moreover, the connecting member 5 is inserted into the through hole 251 and the through hole 261 respectively. Hereinafter, the connecting member 5 inserted into the through hole 251 is referred to as "connecting member 5a", and the connecting member 5 inserted into the through hole 261 is referred to as "connecting member 5b". In addition, when simply referred to as "connecting member 5", it includes "connecting member 5a" and "connecting member 5b".

[0059] In the embodiment, the connection objects of the "connecting member 5a" inserted into the through hole 251 of the first end 25 are the buckle 23 and the convex rod 24. In addition, the connection object of the "connecting member 5b" inserted into the through hole 261 of the second end 26 is the main body case 10 of the watch 100.

[0060] Specifically, the connecting member 5 has a cylindrical portion 51, an inner shaft 52 disposed within the cylindrical portion 51 and having an axially variable length, and a rod portion 53 protruding from the inner shaft 52 substantially orthogonally to the axial direction. The rod portion 53 is formed of a metal such as stainless steel, or a rigid resin such as acrylic, polycarbonate, or ABS. In addition, the material forming the rod portion 53 may be formed of a non-flexible material, and is not limited to the materials exemplified herein. An elastic member such as a coil spring (not shown) is provided on the inner shaft 52. The connecting member 5 in the embodiment is configured as a spring rod (so-called replacement spring rod) capable of expanding and contracting the length of the connecting member 5 (the inner shaft 52 of the connecting member 5) along the axial direction by operating the rod portion 53.

[0061] The elastic member biases the inner shaft 52 in a direction of pushing it outward along the axial direction W. When the inner shaft 52 is pushed by the elastic member in the width direction W, its front end portion becomes a protruding state.

[0062] The replacement spring rod can expand and contract the length of the connecting member 5 only by operating the rod portion 53 without using a special jig or the like.

[0063] In the cylindrical portion 51, a long hole 511 extending along the width direction W is formed corresponding to the movement range of the rod shaft portion 531 of the rod portion 53.

[0064] The rod portion 53 slides within the long hole 511 of the cylindrical portion 51, so that the axial length of the inner shaft 52 can be adjusted against the acting force of the elastic member, and a connected position where the front end portion of the inner shaft 52 becomes a protruding state and a non-connected position where the protruding state is released can be obtained.

[0065] The rod portion 53 has: a rod shaft portion 531 (shaft portion) that is substantially orthogonal to the axial direction W of the connecting member 5 and is connected to the inner shaft 52; and a rod head portion 532 (head portion) that is provided at the free end of the rod shaft portion 531 and is connected to the rod shaft portion 531.

[0066] In Figure 2 etc., a case where the rod portion 53 has a spherical rod head portion 532 is exemplified. However, the rod head portion 532 may have any shape that is easy to hook with fingertips or fingernail tips, and is not limited to a spherical shape.

[0067] Figure 4 is a main part enlarged view of the IV part surrounded by a one-dot chain line in Figure 2 enlarged.

[0068] As Figure 4As shown, at the first end portion 25 of the strap main body 20 in the present embodiment, a cutout portion 252 that is long in the width direction W is formed corresponding to the movement range of the rod shaft portion 531 in the rod portion 53 of the connecting member 5 (connecting member 5a). The rod portion 53 can move along the axial direction (width direction W) within the cutout portion 252, and the aforementioned connected position and non-connected position can be obtained.

[0069] In addition, a rod receiving portion 253 for receiving the rod portion 53 is formed at the first end portion 25 of the strap main body 20 corresponding to the connected position of the rod portion 53.

[0070] Figure 5 It is an enlarged view of the main part of the first end portion of the strap main body. In addition, in Figure 5 the illustration of the buckle 23 and the protruding rod 24 is omitted.

[0071] As Figure 5 shown, etc., the rod receiving portion 253 is provided continuously with the cutout portion 252.

[0072] When in the connected position where the front end portion of the inner shaft 52 is in a protruding state, the rod portion 53 is received in the rod receiving portion 253, so that the position of the rod portion 53 in the axial direction (width direction W) is fixed, and the state of the rod portion 53 being in the connected position is maintained.

[0073] The distance in the width direction W of the strap main body 20 of the portion corresponding to the outer circumference of the rod shaft portion 531 in the rod receiving portion 253 is shorter than the distance in the width direction W of the portion corresponding to the outer circumference of the rod head portion 532, and it is a so-called narrow-width region.

[0074] In addition, when the rod portion 53 is received in the rod receiving portion 253, the region in the width direction W of the strap main body 20 located on the outer circumference of the rod shaft portion 531 of the rod portion 53 includes a press-fitting portion 253a where the rod shaft portion 531 is fixed and a region wider than the press-fitting portion 253a where the rod shaft portion 531 is not fixed. In this way, the portion of the rod receiving portion 253 that receives the rod shaft portion 531 becomes the press-fitting portion 253a formed in a narrow width. The press-fitting portion 253a is formed to have a width equal to or slightly narrower than that of the rod shaft portion 531.

[0075] The region in the width direction W of the strap main body 20 where the rod shaft portion 531 of the rod portion 53 is not fixed, that is, the region wider than the press-fitting portion 253a where the rod shaft portion 531 is not fixed, is located on both sides of the press-fitting portion 253a and has a tapered shape, and the width (distance) of the above-mentioned region in the width direction W of the strap main body 20 becomes wider as it is farther away from the rod shaft portion 531.

[0076] Only a part of the outer periphery of the rod shaft portion 531 contacts the press-fitting portion 253a, and both sides of the press-fitting portion 253a do not contact the rod shaft portion 531. The reason is that considering the operability during rod storage, the contact area with the press-fitting portion 253a should be as small as possible, and at the same time, as the function of the stopper for press-fitting, a structure of press-fitting with a point contact must be adopted. That is, as long as it has the function of the stopper, if the contact area is too large, there will be a negative effect that it is difficult to disassemble. In addition, in the present embodiment, the periphery of the press-fitting portion 253a is conical. It doesn't matter whether the cone is rounded with a C surface or an R surface.

[0077] The watch band main body 20 formed with the rod storage portion 253 is a flexible and soft member as described above. Therefore, even if the press-fitting portion 253a has a width slightly narrower than that of the rod shaft portion 531, the rod shaft portion 531 can be press-fitted, and the rod shaft portion 531 is press-fitted into the press-fitting portion 253a to fix the rod portion 53 in the rod storage portion 253, so as to be in a state where it will not detach from the rod storage portion 253. In addition, the entire watch band main body 20 may not be flexible, but in this case, at least the area where the rod storage portion 253 is formed is flexible.

[0078] In addition, a little margin is provided in the portion of the rod storage portion 253 that accommodates the rod head portion 532, and the fingertip or the tip of the finger nail is hooked on the rod head portion 532, so that it is easy to pull out the rod portion 53 from the rod storage portion 253.

[0079] In this way, in the present application, both sides of the press-fitting portion 253a are conical, and the width (distance) in the width direction W of the watch band main body 20 gradually becomes wider as it moves away from the rod shaft portion 531. That is, when taking the portion where the rod shaft portion 531 is press-fitted as the vertex, both sides of the press-fitting portion (press-fitting portion 253a) in the long side direction L of the watch band gradually expand as they move away from the rod shaft portion 531. Therefore, compared with the case where the press-fitting portion 253a fixed with the rod shaft portion 531 and the surfaces on both sides of the press-fitting portion 253a that are not fixed with the rod shaft portion 531 are parallel to each other, even when the rod portion 53 is repeatedly stored and pulled up, the durability can be maintained.

[0080] In addition, in the state where the rod portion 53 is stored in the rod storage portion 253, the bottom surface (base portion 254) of the rod storage portion 253 where the rod shaft portion 531 is disposed is higher than the bottom surface of the rod storage portion 253 where the rod head portion 532 is disposed. That is, the rod shaft portion 531 is disposed on the base portion 254 that is higher than the lower surface of the rod storage portion 253 where the rod head portion 532 is disposed. Therefore, when the rod portion 53 is pulled up from the flexible watch band main body 20, the rod shaft portion 531 is pushed up and is easily taken out.

[0081] Figure 6 is along Figure 4A main part sectional view of the VI-VI line in [the figure] shows the state where the rod portion is stored.

[0082] At least a part of the strap main body 20 is flexible. Specifically, the area where the rod storage portion 253 is formed is flexible.

[0083] The rod portion 53 includes a rod shaft portion 531 connected to the inner shaft 52 and a rod head portion 532 connected to the rod shaft portion 531. In the state where the rod portion 53 is stored in the rod storage portion 253, the bottom surface (base portion 254) of the rod storage portion 253 where the rod shaft portion 531 is arranged is higher than the bottom surface of the rod storage portion 253 where the rod head portion 532 is arranged.

[0084] In addition, the diameter of the rod head portion 532 is smaller than the diameter of the inner shaft 52. Therefore, even in the state where the rod portion 53 protrudes, that is, the so-called state where the rod portion 53 is pulled up, it is not likely to become an obstacle.

[0085] In addition, Figure 7 indicating the state of pulling up the rod portion from Figure 6 the state shown.

[0086] When the rod portion 53 is pulled up from the rod storage portion 253 to become Figure 7 the state shown, the rod portion 53 can move axially (width direction W) in the notch portion 252 again, and the length of the inner shaft 52 in the axial direction (width direction W) can be adjusted.

[0087] Furthermore, in the present embodiment, as described above, at the mounting side (that is, the second end portion 26) of the end portions of the strap main body 20 of the short strap 21 (female strap) and the long strap 22 (tip strap) that are mounted to the main body case 10, the same connecting member 5 (connecting member 5b) as the connecting member provided at the first end portion 25 of the short strap 21 (female strap) is also provided.

[0088] Figure 8 is an enlarged perspective view of the main part magnifying the second end portion and its periphery. In addition, regarding the structure of the second end portion 26 on the mounting side mounted to the main body case 10, the short strap 21 (female strap) and the long strap 22 (tip strap) are the same.

[0089] As Figure 8As shown, a through-hole 261 penetrating in the width direction W of the strap main body 20 is provided at the second end portion 26, and a connecting member 5 (connecting member 5b) is inserted into the through-hole 261. The connecting member 5b provided in the through-hole 261 also has the same structure as the connecting member 5a, and has a cylindrical portion 51, an inner shaft 52 disposed inside the cylindrical portion 51 and capable of changing in the axial length, and a rod portion 53 protruding from the inner shaft 52 substantially orthogonally to the axial direction. In the cylindrical portion 51, a long hole 511 extending along the width direction W is formed corresponding to the movement range of the rod shaft portion 531 of the rod portion 53.

[0090] In the present embodiment, at the second end portion 26 on the mounting side of the strap main body 20 to the main body case 10, a cutout portion 262 extending along the width direction W is also formed corresponding to the movement range of the rod shaft portion 531 in the rod portion 53 of the connecting member 5 (connecting member 5b).

[0091] In addition, the cutout portion 262 at the second end portion 26 has a length in the width direction W corresponding to the movement range of the rod portion 53, and also extends in the longitudinal direction L of the strap main body 20, and also functions as a rod storage portion capable of laying down and storing the rod portion 53 along the strap main body 20.

[0092] 〔Function〕

[0093] Next, the function of the strap 2 of the present embodiment and the clock 100 including the strap 2 will be described.

[0094] When forming the strap 2, a strap main body 20 of a short strap 21 (female strap) formed of a soft material, a strap main body 20 of a long strap 22 (tip strap), a buckle 23, and a convex rod 24 attached to the first end portion 25 of the short strap 21 (female strap) are prepared. The buckle 23 and the convex rod 24 can be combined and selected by the user according to their preferences, such as materials, colors, textures, etc.

[0095] After determining the buckle 23 and the protruding rod 24 to be installed on the short strap 21 (female strap), insert the connecting member 5 (connecting member 5a) from one side of the through-hole 251 at the first end portion 25 of the short strap 21 (female strap) to the other side. At this time, also insert the connecting member 5 (connecting member 5a) through the through-hole of the protruding rod 24, and engage the protruding rod 24 at substantially the central portion in the width direction W of the strap main body 20. And arrange the buckle 23 in such a manner that the strap main body 20 is sandwiched between the pair of frame legs 231, and move the rod portion 53 in the direction of pressing and compressing the elastic member of the connecting member 5 (connecting member 5a) to be in a non-connecting position where the length of the connecting member 5 (connecting member 5a) becomes shorter. In this state, even if the inner shaft 52 of the connecting member 5 (connecting member 5a) is in a position corresponding to the connecting hole 232 of the buckle 23, when the hand is removed from the rod portion 53, the front end portion of the inner shaft 52 protrudes due to the acting force of the elastic member and is inserted into the connecting hole 232, resulting in a connecting state where the buckle 23 (and the protruding rod 24) as the connecting object and the strap main body 20 are connected by the connecting member 5 (connecting member 5a).

[0096] In the connected state, rotate the connecting member 5 (connecting member 5a) around the axis so that the rod portion 53 is in a position along the strap main body 20, and store the rod portion 53 in the rod storage portion 253 as it is. At this time, press the rod shaft portion 531 into the press-in portion 253a, so that the rod portion 53 does not come off from the rod storage portion 253, and the state where the rod shaft portion 531 and the rod head portion 532 are stored in the rod storage portion 253 is maintained. In addition, since the rod portion 53 cannot move from the connected position, the connecting state where the buckle 23 and the protruding rod 24 are connected to the strap main body 20 by the connecting member 5 (connecting member 5a) is also maintained.

[0097] In addition, regarding the mounting side of the strap main body 20 of the short strap 21 (female strap) and the long strap 22 (tip strap) to the main body case 10, fit the second end portion 26 between the lugs 121 of the main body case 10.

[0098] Specifically, first, the connecting member 5 (connecting member 5b) is inserted through the through-hole 261 formed in the second end portion 26. Then, the rod portion 53 is moved in the direction of pressing and compressing the elastic member of the connecting member 5 (connecting member 5b), and is in a non-connecting position where the length of the connecting member 5 (connecting member 5b) becomes shorter. In this state, even if the inner shaft 52 of the connecting member 5 (connecting member 5b) is in a position corresponding to an unillustrated connecting hole formed in the lug 121, when the hand is removed from the rod portion 53, the front end portion of the inner shaft 52 protrudes due to the acting force of the elastic member, is inserted into the connecting hole, and the main body case 10 and the strap main body 20 to be connected are connected by the connecting member 5 (connecting member 5b) to be in a connected state. Moreover, in the state of being in the connecting position, the connecting member 5 (connecting member 5b) is rotated about the axis and the rod portion 53 is in a position along the strap main body 20, and the rod portion 53 is housed in the cutout portion 262.

[0099] The connecting member 5 (connecting member 5a) is housed in the rod housing portion 253 after being in the connected state, and does not protrude toward the wrist and does not touch the wrist even when the strap 2 is worn on the wrist. In addition, since the rod shaft portion 531 is press-fitted into the press-fitting portion 253a, the rod portion 53 does not detach from the rod housing portion 253 unless intentionally pulled up.

[0100] Similarly, the connecting member 5 (connecting member 5b) is housed in the cutout portion 262 after being in the connected state, so that it does not protrude toward the wrist and does not touch the wrist even when the strap 2 is worn on the wrist. The rod portion 53 can be in a state of being housed in the rod housing portion 253 and a state of being pulled out from the rod housing portion 253 and protruding toward the non-visual confirmation side surface of the watch 100.

[0101] On the other hand, when it is desired to remove and replace the buckle 23 and the convex rod 24, the fingertip or claw tip is hooked on the rod head portion 532 to remove the rod shaft portion 531 from the press-fitting portion 253a, and the rod portion 53 is pulled up. Then, the rod portion 53 is moved in the direction of pressing and compressing the elastic member, and the connecting member 5 (connecting member 5a) is in a non-connecting position. In this state, the buckle 23 can be removed from the strap main body 20. After removing the buckle 23, the connecting member 5 (connecting member 5a) is pulled out from the through-hole 261, and the convex rod 24 can also be removed. Then, the newly selected buckle 23 and convex rod 24 can be installed on the strap main body 20.

[0102] Further, when the short strap 21 (female strap) and the long strap 22 (tip strap) are detached from the main body case 10, similar to the first elastic portion 25 side, the rod portion 53 of the connecting member 5 (connecting member 5a) is pulled up. Then, the rod portion 53 is moved in the direction of pressing and compressing the elastic member so that the connecting member 5 (connecting member 5b) is in a non-connected position. In this state, the front end portion of the inner shaft 52 of the connecting member 5 (connecting member 5a) can be detached from the connecting hole formed in the lug 121 of the main body case 10, and the short strap 21 (female strap) and the long strap 22 (tip strap) can be detached from the strap main body 20.

[0103] Thus, since the connecting member 5 (connecting member 5a and connecting member 5b) of the embodiment is a replacement spring rod (Abie type spring rod) having a rod portion 53, the connection and disconnection between the strap main body 20 and the connection object can be performed without using a special jig or the like, and even an ordinary user can easily disassemble and assemble.

[0104] Then, since the rod portion 53 can be accommodated in the rod accommodating portion 253 and the notch portion 262, the rod portion 53 does not touch the wrist even when the strap 2 is worn.

[0105] 〔Effect〕

[0106] As described above, the strap 2 in the present embodiment includes: a flexible strap main body 20; and a shaft-like connecting member 5 that is attached to an end portion of the strap main body 20, penetrates the strap main body 20 in the width direction W, and is connected to a connection object when the front end portion is in a protruding state. The connecting member 5 includes: a cylindrical portion 51; an inner shaft 52 that is disposed inside the cylindrical portion 51 and whose axial length can be changed; and a rod portion 53 that protrudes from the inner shaft 52 substantially orthogonally to the axial direction. The rod portion 53 slides inside the cylindrical portion 51 to adjust the axial length of the inner shaft 52, and a connected position where the front end portion of the inner shaft 52 is in a protruding state and a non-connected position where the protruding state is released can be obtained. A rod accommodating portion 253 that accommodates the rod portion 53 corresponding to the connected position of the rod portion 53 is formed in the strap main body 20.

[0107] As in the embodiment, a replacement spring rod having a rod portion 53 is used as the connecting member 5 (connecting member 5a and connecting member 5b), and no special jig or technique is required, and anyone can easily disassemble and assemble the connecting member 5 (connecting member 5a and connecting member 5b).

[0108] When such a connecting member 5 is used to connect the buckle 23 and the protruding rod 24 to the first end 25 of the short strap 21 (female strap), the buckle 23 and the protruding rod 24 can be easily disassembled and replaced, and the appearance and impression of the strap 2 can be easily changed. In addition, when it is used to connect the second ends 26 of the short strap 21 (female strap) and the long strap 22 (tip strap) to the main body case 10, the strap 2 attached to the main body case 10 can be easily replaced.

[0109] Then, after the rod portion 53 is connected to the connection object, it can be stored in the rod storage portion 253 or the cutout portion 262 that functions as the rod storage portion.

[0110] Thus, even when using the connecting member 5 (connecting member 5a and connecting member 5b) in which the rod portion 53 protrudes substantially orthogonally to the axial direction, it is possible to achieve a state where the rod portion 53 does not contact the wrist when wearing the strap 2 on the wrist, and a good wearing feeling can be obtained.

[0111] Only a part of the outer periphery of the rod shaft portion 531 is press-fitted into the press-fitting portion 253a, and both sides of the press-fitting portion 253a do not contact the rod shaft portion 531. Therefore, it functions as a stopper, and since the contact area is small, it is easy to disassemble. In addition, durability can be maintained. Moreover, the rod shaft portion 531 is disposed on the base portion 254 that is higher than the lower surface of the rod storage portion 253 where the rod head portion 532 is disposed. Therefore, when the rod portion 53 is pulled up from the flexible strap main body 20, the rod shaft portion 531 can be pushed up and easily removed. In addition, since the diameter of the rod head portion 532 is smaller than the diameter of the inner shaft 52, even in a state where the rod portion 53 protrudes, that is, in a state where the rod portion 53 is pulled up, it is not likely to become an obstacle.

[0112] In addition, the connecting member 5 may be provided on at least any one of one end side (i.e., the first end 25) and the other end side (i.e., the second end 26) of the strap 2 (the short strap 21 (female strap) and the long strap 22 (tip strap)).

[0113] Therefore, especially when it is not necessary for ordinary users to perform replacement, the strap main body 20 can also be connected to the connection object by a method that does not use the connecting member 5.

[0114] In the present embodiment, an example is shown in which the connecting member 5 as a replacement spring rod is provided on one end side (i.e., the first end 25) of the short strap 21 (female strap) in the strap 2, and on the other end side (i.e., the second end 26) of the short strap 21 (female strap) and the long strap 22 (tip strap). However, for example, the connecting member 5a as a replacement spring rod may be provided only on the first end 25 of the short strap 21 (female strap), and a normal spring rod or the like without the rod portion 53 may be used in the attachment and detachment of the strap 2 itself with respect to the main body case 10.

[0115] In addition, in the present embodiment, the rod storage portion 253 is disposed corresponding to the connecting member 5 (connecting member 5a) on the side (i.e., the first end portion 25) of the frame-shaped buckle 23 and the protruding rod 24 provided at the end portion of the watch band main body 20.

[0116] If the side (i.e., the first end portion 25) provided with the buckle 23 and the protruding rod 24 does not have a relatively thick thickness and protrudes toward the back surface of the watch band main body 20, it is likely to touch the wrist when the watch band 2 is worn on the wrist, and the wearing feeling deteriorates. Regarding this point, since the rod storage portion 253 can be provided at the first end portion 25 to store the rod portion 53, even if the rod portion 53 protrudes substantially orthogonally to the axial direction, the rod portion 53 will not touch the wrist when the watch band 2 is worn, and a comfortable wearing feeling can be achieved.

[0117] In addition, the rod portion 53 of the present embodiment has a rod shaft portion 531 substantially orthogonal to the axial direction of the connecting member 5 and a rod head portion 532 provided at the free end of the rod shaft portion 531. The portion of the rod storage portion 253 that stores the rod shaft portion 531 becomes a press-fitting portion 253a formed to be narrow.

[0118] Thus, when the rod portion 53 is stored in the rod storage portion 253, the rod shaft portion 531 can be reliably inserted, and it is possible to prevent the rod portion 53 from detaching from the rod storage portion 253 and coming into contact with the wrist during the installation process. In addition, the watch band main body 20 in the embodiment is a flexible member formed of a soft material, so it is easy to press the rod shaft portion 531 into the press-fitting portion 253a, and after the press-fitting, the rod portion 53 can also be easily pulled up by hanging a finger or a claw on the rod head portion 532 or the like.

[0119] In addition, when the watch band as described above is attached to the watch main body 1 to form a watch (wristwatch) 100, an ordinary user can easily disassemble, attach, and replace the watch band 2 attached to the watch main body 1. Also, the buckle 23 and the protruding rod 24 of the watch band 2 can be easily disassembled and replaced. Therefore, the appearance and impression of the watch band 2 can be easily changed. Thus, a watch 100 with a rich variety of changes can be realized, and excellent design effects are expected.

[0120] 〔Modification Example〕

[0121] In addition, although one embodiment of the present invention has been described above, the present invention is not limited to this embodiment, and various modifications can be appropriately made without departing from the gist thereof.

[0122] For example, in the present embodiment, an example is shown in which the connecting members 5 (connecting members 5a and 5b), which are replacement spring rods having a rod portion 53, are provided on one end side (i.e., the first end portion 25) of the short strap 21 (female strap) in the watchband 2 and on the other end side (i.e., the second end portion 26) of the short strap 21 (female strap) and the long strap 22 (tip strap). However, the replacement spring rod, i.e., the connecting member 5, may be only either the connecting member 5a or the connecting member 5b.

[0123] For example, only the connecting member 5a provided at the first end portion 25 of the short strap 21 (female strap) may be used as the replacement spring rod, and a spring rod without the rod portion 53 may be provided at the second end portion 26 of the short strap 21 (female strap) and the long strap 22 (tip strap). In this case, the buckle 23 and the protruding rod 24 can be easily disassembled, replaced, and changed without using a jig or the like.

[0124] Conversely, only the connecting member 5b provided at the second end portion 26 of the short strap 21 (female strap) and the long strap 22 (tip strap) may be used as the replacement spring rod, and a spring rod without the rod portion 53 may be provided at the first end portion 25 of the short strap 21 (female strap). In this case, the watchband 2 itself can be easily disassembled, replaced, and changed without using a jig or the like.

[0125] In addition, in the present embodiment, a rod housing portion 253 having a press-fitting portion 253a is provided corresponding to the connecting member 5a provided at the first end portion 25 of the short strap 21 (female strap), and a notch portion 262 is provided corresponding to the connecting member 5b provided at the second end portion 26 of the short strap 21 (female strap) and the long strap 22 (tip strap). The notch portion 262 shown in the embodiment is a hole formed by cutting the range in which the movement operation of the rod portion 53 can be performed at the second end portion 26. In particular, a press-fitting portion for pressing the rod shaft portion 531 is not provided, but a structure similar to the rod housing portion 253, such as a press-fitting portion, may also be provided in the notch portion 262 to maintain the state in which the rod portion 53 is along the watchband main body 20 and is difficult to disengage.

[0126] The second end portion 26 mounted on the main body case 10 has a thickness as compared with the first end portion 25. Even when the rod portion 53 tilts away from the watchband main body 20 side toward the side worn on the wrist, the contact with the wrist is less, and the possibility of impairing the wearing feeling is small. Therefore, as long as a space for moving the rod portion 53 can be ensured, there are fewer problems even if a replacement spring rod having the rod portion 53 is used as the connecting member 5b.

[0127] However, depending on the thickness of the second end portion 26 and the structure of the portion where the strap 2 is attached to the main body case 10, it is also considered that if the rod portion 53 moves away from the side of the strap main body 20, the rod portion 53 may touch the wrist when the strap 2 is worn. In such a case, it is preferable that the cutout portion 262 provided in the second end portion 26 also has a structure such as a press-fitting portion that maintains the state where the rod portion 53 follows the strap main body 20 and is difficult to come off.

[0128] In addition, in the present embodiment, an example in which the strap 2 is connected to the main body case 10 of the clock 100 has been described, but the strap 2 is not limited to the clock strap 2 attached to the main body case 10 of the clock 100.

[0129] For example, as a strap connected to the main body case of various devices (such as a smart watch, a pedometer, a heart rate monitor, etc.) fixed to the body by the strap 2, the strap 2 of the present invention can be applied.

[0130] Moreover, as long as the strap 2 has a structure that can be connected to a connection object, it can be widely applied. For example, it can also be various bands, bracelet-like band portions, etc.

[0131] Several embodiments of the present invention have been described above, but the scope of the present invention is not limited to the above-described embodiments, and includes the scope of the invention described in the claims and its equivalent scope.
