Description

[Technical field]

[0001] The present invention relates to a band and a watch. [Background technology]

[0002] Conventionally, a band for attaching a watch to the body such as the arm has been known that has multiple links connected by pins. The length of such a band can be adjusted to fit the user's body by removing the pins and attaching and detaching the links. Since attaching and detaching the links requires tools and skills, adjustment of the band is generally performed by a skilled technician. However, in recent years, the number of users who purchase watches through electronic commerce has been increasing, and there is a demand for users who do not have tools or skills to be able to attach and detach the links and adjust the band themselves. On the other hand, there is also a demand for the links to be properly connected so that they do not come off during normal use of the watch.

[0003] Patent Document 1 describes a band in which a piece is connected by fitting a pin into a loop formed by folding in both ends of a top plate that covers the upper surface of the piece. In this band, the loop is not completely closed so that the pin can be removed, and the pin is held in the loop by abutting against a spring that is arranged inside the piece so as to face the loop. [Prior art documents] [Patent documents]

[0014] [Figure 1] FIG. [Diagram 2] FIG. [Diagram 3] FIG. [Figure 4] FIG. [Diagram 5] FIG. 4 is a partially enlarged cross-sectional view of an adjustment piece 13. [Figure 6] FIG. 4 is a partially enlarged cross-sectional view of an adjustment piece 13. [Figure 7] FIG. [Figure 8] FIG. [Figure 9] FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] Hereinafter, various embodiments of the present invention will be described with reference to the drawings. It should be noted that the technical scope of the present invention is not limited to these embodiments, but covers the inventions described in the claims and their equivalents.

[0016] FIG. 1 is a perspective view of a watch 1 according to an embodiment. The watch 1 has a main body 11 and a band 12. The main body 11 is a mechanical watch, a quartz analog watch, a digital watch, or the like, that has a timekeeping function. The band 12 has a 12 o'clock side band 121 that is connected to the 12 o'clock side of the main body 11, and a 6 o'clock side band 122 that is connected to the 6 o'clock side of the main body 11. The end of the 12 o'clock side band 121 that is not connected to the main body 11 and the end of the 6 o'clock side band 122 that is not connected to the main body 11 are connected to each other via a clasp (not shown) and formed into a ring shape. The user wears the watch 1 by passing the arm or the like through the ring-shaped band 12. In the following description, the side that is visible from the outside when the user wears the watch 1 (the upper side of FIG. 1) may be referred to as the upper side of the watch 1, and the side that comes into contact with the user (the lower side of FIG. 1) may be referred to as the lower side of the watch 1.

[0017] The band 12 has a plurality of links connected along its extension direction. Each of the links has a connecting pin, which will be described later, and is connected to the other links in the extension direction of the band 12 by holding the connecting pins of the other links. The plurality of links has an adjustment link 13 that is connected to the other links so that it can be removed by the user, and a fixed link 14 that is connected to the other links so that it cannot be removed by the user. In the example shown in FIG. 1, the plurality of links are arranged such that the fixed link 14 is closer to the main body 11, and the adjustment link 13 is closer to a clasp (not shown). The user can adjust the length of the band 12 by removing the adjustment link 13 from the band 12. The extension direction of the band 12 is an example of a predetermined direction.

[0018] Fig. 2 is a perspective view of the adjustment piece 13, and Fig. 3 is an exploded perspective view of the adjustment piece 13. The adjustment piece 13 has a center piece 15 and a pair of outer pieces 16 arranged on either side of the center piece 15. The pair of outer pieces 16 hold both ends of a connecting pin P1. The center piece 15 is formed so as to be able to hold the connecting pin P1. When the center piece 15 holds the connecting pin P1 of another adjustment piece 13, the two adjustment pieces 13 are connected by the connecting pin P1.

[0019] The center piece 15 has a body 17 and a plate material 18 that covers the upper surface of the body 17 and extends in the extension direction of the band 12. The body 17 is made of a resin such as ABS resin or a metal such as stainless steel or titanium. The plate material 18 is made of an elastic metal such as stainless steel or titanium.

[0020] A pair of side surfaces of the body 17 extending in the extension direction of the band 12 are formed with recesses 171 at approximately the center thereof so as to connect with the upper surface of the body 17. The body 17 is also formed with a body through hole 172 penetrating the bottom surface of the pair of recesses 171. A C-ring 173 is inserted into the body through hole 172. An engagement portion 174 for engaging with the outer link 16 is formed at one end of the body 17 in the extension direction of the band 12. A curved surface 175 is formed at the other end of the body 17 in the extension direction of the band 12. A notched inclined surface 176 is formed at the lower end of the curved surface 175 so as to connect the curved surface 175 and the lower surface of the body 17.

[0021] Plate material 18 has a pair of extending portions 181 that respectively extend to a pair of side surfaces of body portion 17 that extend in the extension direction of band 12. For example, extending portion 181 is formed by bending a part of plate material 18. The pair of extending portions 181 each fit into a recess 171 formed in the side surface of body portion 17. Preferably, when extending portion 181 is fitted into recess 171, the surface of extending portion 181 forms the same plane as the side surface of body portion 17. This makes the side surface of center link 15 flat and increases the contact area between center link 15 and outer link 16, so that center link 15 and outer link 16 are appropriately joined.

[0022] Plate material through holes 182 are formed in each of the pair of extending portions 181 so as to face the corresponding body portion through holes 172. Plate material through holes 182 are formed so as to be coaxial with body portion through holes 172 when extending portions 181 are fitted into recesses 171.

[0023] Plate material 18 extends from one end of trunk portion 17 on the side where curved surface 175 is formed. The portion of plate material 18 extending from trunk portion 17 is rolled in the direction of trunk portion 17 to form holding portion 183 that holds a connecting pin, which will be described later.

[0024] The pair of outer links 16 are connected to each other by a columnar connecting portion 161. In the example shown in Figs. 2 and 3, the connecting portion 161 is formed below the outer link 16 and has a rectangular columnar shape. A first through hole 162 and a second through hole 163 are formed in the pair of outer links 16 so as to face each other. The first through hole 162 has a shape that allows the insertion of a connecting pin P2 for connecting the center link 15 and the pair of outer links 16 to form the adjustment link 13. The second through hole 163 has a shape that allows the insertion of a connecting pin P1 for connecting the pair of outer links 16 and connecting a plurality of adjustment links 13.

[0025] The engaging portion 174 of the body 17 has a shape complementary to the connecting portion 161 so as to be engageable with the connecting portion 161 of the outer link 16. In the example shown in Fig. 2 and Fig. 3, since the connecting portion 161 is a square prism, the engaging portion 174 is formed by a rectangular cutout. The engaging portion 174 is formed such that the plate material through hole 182 and the body through hole 172 face the first through hole 162 when engaged with the connecting portion 161.

[0026] With the engaging portion 174 of the body 17 engaged with the connecting portion 161 of the outer link 16, the coupling pin P2 is inserted through the first through-hole 162 of the pair of outer links 16, the plate material through-hole 182 of the pair of extension portions 181, and the body through-hole 172. The inserted coupling pin P2 penetrates the C-ring 173 inserted in advance into the body through-hole 172. As a result, the coupling pin P2 fits into the inner circumference of the C-ring 173. In addition, the penetration of the coupling pin P2 expands the outer diameter of the C-ring 173, and the outer circumference of the C-ring 173 fits into the inner circumference of the body through-hole 172. In this way, the coupling pin P2 is held in a state of being inserted through the first through-hole 162, the plate material through-hole 182, and the body through-hole 172.

[0027] The body 17 and the plate material 18 are connected by a connecting pin P2 inserted through the plate material through hole 182 and the body through hole 172. That is, the connecting pin P2 is inserted through the plate material through hole 182 and the body through hole 172, thereby restricting the parallel movement of the plate material 18 relative to the body 17. The extension portion 181 of the plate material 18 fits into the recess 171, thereby restricting the rotation of the plate material 18 about the connecting pin P2.

[0028] The inner link 15 and the outer link 16 are connected by a connecting pin P2. That is, the connecting pin P2 is inserted through the first through hole 162 of the outer link 16 and the body through hole 172 of the body 17, thereby restricting the inner link 15 from moving parallel to the outer link 16. The engaging portion 174 of the body 17 engages with the connecting portion 161 of the outer link 16, thereby restricting the inner link 15 from rotating about the connecting pin P2.

[0029] The pair of outer links 16 hold both ends of the connecting pin P1 inserted into the second through hole 163. That is, the connecting pin P1 is inserted into the second through hole 163 of the pair of outer links 16. Also, plugs P1a are fitted into the second through hole 163 so as to close both ends of the inserted connecting pin P1. In this way, the connecting pin P1 is held in a state of being inserted into the second through hole 163.

[0030] Fig. 4 is a cross-sectional view of the adjustment piece 13, and Figs. 5 and 6 are partially enlarged cross-sectional views enlarging the vicinity of the holding portion 183 of the adjustment piece 13. Figs. 4, 5, and 6 are cross-sectional views taken along the line IV-IV in Fig. 2. Figs. 4 and 5 show a state in which the holding portion 183 holds the connecting pin P1 of another adjustment piece 13, thereby connecting two adjustment pieces 13 together via the connecting pin P1. Fig. 6 shows a state in which the holding portion 183 does not hold the connecting pin P1 of the other adjustment piece 13.

[0031] The retaining portion 183 of the plate material 18 is formed so that the minimum distance D between the retaining portion 183 and the body portion 17 is smaller than the outer diameter of the connecting pin P1 when no external force is applied, and retains the connecting pin P1 of the other adjusting piece 13 on the inside. By retaining the connecting pin P1 of the other adjusting piece 13 in the retaining portion 183, the multiple adjusting pieces 13 are connected by the connecting pin P1.

[0032] The tip 184 of the holding portion 183 is folded toward the inside of the holding portion 183. As a result, a bent portion 185 is formed in the plate material 18, and the tip 184 functions as a leaf spring that applies an elastic force in a direction E in which the plate material 18 returns to its original state from the folded state. The tip 184 presses the connecting pin P1 held by the holding portion 183 toward the body portion 17 inside the holding portion 183 by the elastic force of the folded tip 184, and fixes it. As a result, the connecting pin P1 does not move inside the holding portion 183 due to the simple configuration of folding the tip of the holding portion 183, so that the connecting pin P1 is prevented from falling off the holding portion 183 due to vibration or the like, and the adjustment piece 13 is prevented from coming off the band 12. That is, the tip 184 of the holding portion 183 is folded toward the inside of the holding portion 183, so that the multiple adjustment pieces 13 are appropriately connected.

[0033] In addition, by folding in the tip 184 of the holding portion 183, the surface S of the bent portion 185 facing the body portion 17 is rounded. This makes it easier for the connecting pin P1 to enter the inside of the holding portion 183, facilitating the attachment of the adjustment piece 13. In addition, safety for the user is improved compared to when the surface S is a sharp bent surface.

[0034] The curved surface 175 of the body 17 continues to a position where the distance from the holding portion 183 is the minimum distance D. As a result, when the connecting pin P1 is removed from the holding portion 183, the connecting pin P1 is guided by the curved surface 175 to the outside of the holding portion 183, making it easier to remove the adjustment piece 13. In addition, the tip portion 184 presses and fixes the connecting pin P1 against the curved surface 175. As a result, the connecting pin P1 continues to be guided by the curved surface 175 until the connecting pin P1 changes from a held state to a removed state, making it easier to remove the adjustment piece 13.

[0035] A notched inclined surface 176 is formed at the bottom of the curved surface 175 so as to connect the curved surface 175 and the bottom surface of the body 17. This makes it easier for the connecting pin P1 to enter the inside of the holding portion 183, facilitating the attachment of the adjustment piece 13. Note that, although the inclined surface 176 is formed as a flat surface in the examples shown in Figs. 4 and 5, the inclined surface 176 is not limited to such an example. The inclined surface 176 may be formed as a curved surface, or may be formed by combining a plurality of flat or curved surfaces.

[0036] When removing the adjustment piece 13 from the band 12, the user pulls the adjustment piece 13 upward. At this time, the connecting pin P1 held by the holding part 183 does not move upward because both ends of the connecting pin P1 are held by the outer piece 16 of the other adjustment piece 13. Therefore, the connecting pin P1 moves downward relative to the holding part 183. Since the connecting pin P1 is pressed toward the curved surface 175 by the tip part 184, it moves between the holding part 183 and the body part 17 while in contact with the curved surface 175, as shown by the arrow F in FIG. 5. Since the minimum distance D between the holding part 183 and the body part 17 is smaller than the outer diameter G of the connecting pin P1, the holding part 183, which is an elastic body, is elastically deformed by being pressed by the connecting pin P1 so that the gap between the holding part 183 and the body part 17 widens. When the minimum distance D between the holding part 183 and the body part 17 becomes equal to or larger than the outer diameter of the connecting pin P1 in this state, the connecting pin P1 is removed from between the holding part 183 and the body part 17. That is, the holding portion 183 holds the connecting pin P1 of the other adjustment piece 13 in a detachable manner.

[0037] When attaching the adjustment piece 13 to the band 12, the user presses the adjustment piece 13 against the connecting pin P1 of another adjustment piece 13 from above. At this time, the surface of the bent portion 185 facing the body portion 17 is rounded, and the inclined surface 176 is formed on the lower surface of the body portion 17, so that the connecting pin P1 enters between the holding portion 183 and the body portion 17. Since the minimum distance D between the holding portion 183 and the body portion 17 is smaller than the outer diameter G of the connecting pin P1, the holding portion 183, which is an elastic body, is pressed against the connecting pin P1. Since the surface of the bent portion 185 facing the body portion 17 is rounded, the contact surface S of the holding portion 183 with the connecting pin P1 is inclined without being perpendicular to the direction in which the connecting pin P1 is pushed in. In the example shown in FIG. 6, the connecting pin P1 is pushed upward, and the contact surface S is inclined with respect to the horizontal direction. Since the pressing force that bent portion 185 receives from connecting pin P1 is generally in a direction perpendicular to contact surface S, holding portion 183 is elastically deformed by the pressing force so that the gap between holding portion 183 and body portion 17 widens. In this state, when the minimum distance D between holding portion 183 and body portion 17 becomes equal to or greater than the outer diameter G of connecting pin P1, connecting pin P1 enters the inside of holding portion 183 and is held by holding portion 183. In this way, the user can attach and detach adjustment piece 13 without using tools.

[0038] 4 and 5, two adjustment pieces 13 are connected, but the adjustment piece 13 and the fixed piece 14 are also connected in the same manner. That is, the holding portion 183 of the adjustment piece 13 holds the connecting pin of the fixed piece 14, thereby connecting the fixed piece 14 and the adjustment piece 13.

[0039] As described above, the band 12 has a plurality of links connected by the connecting pin P1, and a plurality of links connected to other links in the extension direction of the band 12 by holding the connecting pin P1 of other links. The plurality of links has an adjustment link 13 that is removable from the other links. The adjustment link 13 has a body 17 and a holding part 183 that is formed of an elastic body that extends from one end of the body 17 in a predetermined direction and is wound toward the body 17, and that holds the connecting pin P1 removably between the body 17 and the adjustment link 13. The tip 184 of the holding part 183 is folded toward the inside of the holding part 183, and the held connecting pin P1 is pressed and fixed by an elastic force. In this way, the band 12 can appropriately connect the links with a simple structure, and allows the user to attach and detach the links without using tools.

[0040] Furthermore, body 17 has a curved surface 175 facing holding portion 183. Holding portion 183 presses connecting pin P1 against curved surface 175 to fix it. This allows connecting pin P1 to be guided along curved surface 175 to the outside of holding portion 183, making it easy to remove adjustment piece 13. Generally, when a user adjusts band 12, the user sequentially removes multiple pre-connected adjustment pieces 13 until band 12 reaches an appropriate length. Therefore, by making it easy to remove adjustment pieces 13, the convenience of the user adjusting the band is greatly improved.

[0041] The adjustment piece 13 further includes a plate material 18, which is an elastic body that covers the upper surface of the body 17 and is formed separately from the body 17 and stretches in a predetermined direction. By forming the plate material 18 separately from the body 17, the structure of the band 12 becomes simpler. That is, by forming the plate material 18 separately from the body 17, the holding portion 183 can be formed by rolling the flat plate-like plate material 18, and the extending portion 181 can be formed by bending the plate material 18. In addition, since the body 17 does not need to have elasticity, it can be formed from resin or the like that is easy to mold. In this way, by forming the plate material 18 separately from the body 17, the structure of the adjustment piece 13 becomes simpler and the manufacturing thereof becomes easier.

[0042] Furthermore, a body through hole 172 is formed in a side surface of body 17 extending in a predetermined direction. Plate material 18 has an extending portion 181 that extends to the side surface of body 17 so as to cover body through hole 172. Body 17 and plate material 18 are joined by a joining pin P2 that passes through body through hole 172 and plate material through hole 182. This allows body 17 and plate material 18, which are formed as separate bodies, to be appropriately joined together.

[0043] The following modifications may be applied to the watch 1 and band 12.

[0044] In the above description, the plate material 18 is formed separately from the body 17, but the plate material 18 may be formed integrally with the body 17. That is, the body 17 may be formed of an elastic body, and a holding portion may be formed by winding a portion extending from one end in a predetermined direction toward the body 17. This eliminates the need to form the recess 171 of the body 17 and the extension 181 of the plate material 18 for connecting the body 17 and the plate material 18, making the structure of the band 12 simpler. Also, a uniform texture similar to that of conventional watch bands is expressed.

[0045] In the above description, the body 17 has the curved surface 175, but the body 17 does not have to have the curved surface 175. For example, the side surface of the body 17 facing the holding portion 183 may be a flat surface, or a curved surface formed by combining a plurality of flat surfaces. In this case, when the adjustment piece 13 is pulled up, the holding portion 183 elastically deforms and the connecting pin P1 is removed, so that the user can attach and detach the piece without using tools. This also makes it easier to form the body 17.

[0046] In the above description, the outer link 16 has the connecting portion 161, but the outer link 16 does not have to have the connecting portion 161. This allows the center link 15 to rotate relative to the outer link 16 around the connecting pin P2 as an axis, allowing the band 12 to bend more freely, improving convenience for the user.

[0047] In the above description, the band 12 has the adjustment link 13 and the fixed link 14, but it may have only the adjustment link 13.

[0048] In the above description, the coupling pin P2 is held in a state where it is inserted into the body through-hole 172 by the C-ring 173, but this is not limited to an example. For example, the coupling pin P2 may be held by a plug, similar to the connecting pin P1. The coupling pin P2 may be a spring rod with an elastic body such as a coil spring built in and both ends are expandable and contractible, and may be held by the elastic force of the built-in elastic body. The coupling pin P2 may also be any pin used in conventional watches.

[0049] Fig. 7 is an exploded perspective view of an adjustment link 23 of a band according to another embodiment, and Fig. 8 is a cross-sectional view of the adjustment link 23. Fig. 8 is a cross-sectional view of the same cross section as Fig. 4. The adjustment link 23 has a center link 25 and a pair of outer links 26 arranged to sandwich the center link 25. The center link 25 and the pair of outer links 26 are connected by a connecting pin P2. The multiple adjustment links 23 are connected by a connecting pin P1.

[0050] The outer link 26 differs from the outer link 16 in that it does not have a connecting portion 161. That is, the pair of outer links 26 are each formed with a first through hole 262 for inserting the connecting pin P2 and a second through hole 263 for inserting the connecting pin P1, facing each other.

[0051] The center piece 25 has a body 27 and a plate material 28 that covers the upper surface of the body 27 and extends in a predetermined direction. The body 27 differs from the body 17 in that it does not have the recess 171, the C-ring 173, and the engagement portion 174. The body 27 also differs from the body 17 in that it further has a notch 277 instead of the inclined surface 176. Since the other configurations of the body 27 are similar to those of the body 17, the same reference numerals are used and the description is omitted. The plate material 28 differs from the plate material 18 in that it does not have an extension portion 181. The plate material 28 also differs from the plate material 18 in that it further has a bent portion 286. Since the other configurations of the plate material 28 are similar to those of the plate material 18, the same reference numerals are used and the description is omitted. In the adjustment piece 23, since the center piece 25 does not have the C-ring 173, the coupling pin P2 is held by a plug P2a that fits into the first through hole 262, similar to the connecting pin P1.

[0052] The notch 277 is formed at the connection between the lower surface of the body 27 and the side surface facing the holding portion 183. The end of the plate material 28 on the side where the holding portion 183 is not formed is bent so as to cover the upper surface of the body 27, the side surface opposite the side surface facing the holding portion 183, and the lower surface. In addition, the tip of the plate material 28 on the side where the holding portion 183 is not formed, i.e., the tip surface that contacts the lower surface of the body 27, is folded toward the body 27 to form a bent portion 286. The plate material 28 covers the upper surface, side surface, and lower surface of the body 27, and the bent portion 286 of the plate material 28 engages with the notch 277 of the body 27, thereby joining the body 27 and the plate material 28.

[0053] Preferably, the depth F of the notch 277 in the extension direction of the band is greater than the thickness of the plate material 28. This prevents a part of the bent portion 286 from protruding from the notch 277 when the body portion 27 and the plate material 28 are joined, and prevents the connecting pin P1 from becoming an obstacle when being removed from the holding portion 183, making it easier to remove the adjustment piece 23.

[0054] As described above, the notch 277 is formed on the underside of the body 27, and the end of the plate material 28 on the side where the holding portion 183 is not formed is folded toward the body 27 to form the bent portion 286. The plate material 28 covers the upper, side and lower surfaces of the body 27, and the bent portion 286 engages with the notch 277, thereby joining the body 27 and the plate material 28. This makes it possible to connect the pieces with a simpler structure. That is, the plate material 28 can be formed simply by bending an elastic flat plate.

[0055] Also, cutout portion 277 is formed at the connection portion between the underside of body portion 27 and the side surface facing holding portion 183. This makes it difficult to see the boundary between body portion 27 and plate material 28 from the outside, and creates a uniform texture similar to that of conventional watches.

[0056] In the above description, the notch 277 is formed at the connection between the underside of the body 27 and the side surface facing the holding portion 183, but this is not limited to the example. Instead of the notch 277, a groove may be formed at any position on the underside of the body 27 with which the bent portion 286 of the plate material 28 can engage. Also, a groove may be formed on the side surface of the body 27 with which the bent portion 286 can engage. In these cases as well, the body 27 and the plate material 28 are appropriately joined together.

[0057] In the above description, the body 27 does not have a C-ring, but it may have a C-ring as in the case of the body 17, and the connecting pin P2 may be held by the C-ring. In this case, the adjustment piece 23 does not need to have a plug P2a. Also, the connecting pin P2 may be any pin used in conventional watches.

[0058] FIG. 9 is a perspective view of an adjustment piece 33 of a band according to another embodiment. The adjustment piece 33 has two first links 35 and three second links 36 arranged alternately. The configurations of the first links 35 and the second links 36 are similar to those of the center link 15 and the outer link 16, respectively, and therefore the same reference numerals are used and the description is omitted. That is, among the three second links 36, two adjacent second links 36 sandwiching the first link 35 are connected to each other by a columnar connecting portion 161 provided below. The two first links 35 and the three second links 36 are connected by one connecting pin P2. The two first links 35 have a holding portion 183 and detachably hold the connecting pin P1 of the other adjustment piece 33. As a result, the multiple adjustment pieces 33 are connected by the connecting pin P1.

[0059] In this way, the adjustment piece 33 has a multi-stage structure with multiple first pieces 35. This allows the user to have a more delicate impression. In conventional watches, the pieces need to be attached and detached by removing the pins that connect the pieces, but when removable pins are used, it may be difficult to realize a multi-stage structure like the adjustment piece 33. For example, when a spring bar with expandable ends is used as the pin, the spring needs to have a certain length to obtain the desired elasticity. Therefore, since the pin cannot be shortened, it is difficult to reduce the width of the middle piece in the extension direction of the pin, and it may be difficult to realize a multi-stage structure. Since the adjustment piece 33 allows the pieces to be attached and detached without removing the pin, it is possible to realize a multi-stage structure regardless of the type of pin.

[0060] In the above description, the adjustment link 33 has two first links 35 and three second links 36, but is not limited to this example and may have more first links 35 and second links 36. Also, in the above description, the first links 35 and second links 36 have the same configuration as the inner link 15 and outer link 16, respectively, but they may have the same configuration as the inner link 25 and outer link 26.

[0061] It should be understood by those skilled in the art that various changes, substitutions, and modifications can be made to the present invention without departing from the scope of the present invention. For example, the above-described embodiments and modifications may be appropriately combined within the scope of the present invention. [Explanation of symbols]
