The first and second pin members move to the engaged position when the operation member is moved to the first position, whereas move to the released position when the operation member is moved to the second position. The engaged position, in a width direction, allows each pin to be outside the side of the housing, and in a longitudinal direction, is closer to the coupling part than the released position. The released position, in the width direction, allows each pin to be inside the side of the housing, and in the longitudinal direction, is closer to the engaging part than the engaged position.SELECTED DRAWING: Figure 2

Description

Technical Field

[0001] The present invention relates to bands and watches.

Background Art

[0002] In a wristwatch, a spring bar is usually used when connecting the watch case and the band. At this time, the position of the through hole formed in the end piece of the band through which the spring bar is inserted and the hole formed in the case into which both ends of the spring bar are inserted are intentionally shifted. When both ends of the spring bar inserted through the through hole of the end piece are inserted into the holes of the case, the end piece is urged toward the main body side by bending the spring bar, thereby preventing a gap from occurring between the case and the end piece. Such attachment of the spring bar requires dedicated tools and techniques, so it was not possible for users to easily attach it. For this reason, as described in Patent Document 1, a band connection structure that can be easily attached and detached by the user has been proposed. In Patent Document 1, the watch case and the band are connected using a spring bar with a lever, and the user can easily attach and detach the band to and from the watch case by sliding the lever.

Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the band structure of Patent Document 1, since the spring bar is slid in the width direction of the band by a lever operation to be attached to and detached from the case, it is necessary to provide the positions of the spring bar and the holes on the case side in a straight line. For this reason, due to variations in parts, there are problems such as play and gaps between the end piece and the case, and these are prominently large, resulting in a decrease in appearance quality.

Means for Solving the Problem

[0005] The band of the present disclosure is a band attached to a watch case having a first engagement hole and a second engagement hole facing each other, and includes a band body and an end member provided at an end of the band body. The end member includes a first pin member having a first pin that engages with the first engagement hole, a second pin member having a second pin that engages with the second engagement hole and is spaced apart from the first pin member in the width direction of the band, an operation member that moves between a first position and a second position, a housing that holds the first pin member, the second pin member, and the operation member, and a guide portion that guides the first pin member and the second pin member to move between an engagement position and a release position with respect to the housing. The housing has an engagement portion that engages with the watch case and a connection portion that is provided away from the engagement portion in the longitudinal direction of the band and to which the band body is connected. The first pin member and the second pin member move to the engagement position when the operation member moves to the first position and move to the release position when the operation member moves to the second position. The engagement position is a position where the first pin and the second pin are located outside the side surface of the housing in the width direction of the band and closer to the connection portion than the release position in the longitudinal direction of the band orthogonal to the width direction. The release position is a position where the first pin and the second pin are located inside the side surface of the housing in the width direction of the band and closer to the engagement portion than the engagement position in the longitudinal direction of the band.

[0006] The watch of the present disclosure is characterized by including the band.

[0007] The clock of the present disclosure includes a clock case having a first engagement hole and a second engagement hole facing each other, a band body, and a band including an end member provided at an end of the band body and attached to the clock case. The end member includes a first pin member having a first pin engageable with the first engagement hole, a second pin member having a second pin engageable with the second engagement hole and spaced apart from the first pin member in the width direction of the band, an operation member movable between a first position and a second position, and a housing holding the first pin member, the second pin member, and the operation member. The first pin member and the second pin member are provided to be movable to an engagement position where they engage with the first engagement hole and the second engagement hole when the operation member is moved to the first position, and to a release position where they do not engage with the first engagement hole and the second engagement hole when moved to the second position.

Mode for Carrying Out the Invention

[0009] [First Embodiment] Hereinafter, the clock 1 according to the first embodiment of the present disclosure will be described with reference to the drawings. FIG. 1 is a perspective view showing a main part of the clock 1 of the first embodiment. As shown in FIG. 1, the clock 1 has a clock body 2 and a band 3. In the following description, the longitudinal direction of the band 3 is the X-axis direction, the width direction of the band 3 is the Y-axis direction, and the thickness direction of the band 3 is the Z-axis direction. These X-axis, Y-axis, and Z-axis are directions orthogonal to each other.

[0010] The clock body 2 includes a clock case 10 and a cover glass and a back cover (not shown). The clock case 10 includes a body 11 and a tube 15. The body 11 is a cylindrical member formed of metal, and a dial plate, a movement, etc. (not shown) are arranged inside. The tubes 15 are provided at the 6 o'clock direction and the 12 o'clock direction of the body 11, respectively. Each tube 15 is provided in a pair protruding from the side surface 12 of the body 11, and a first engagement hole 16 and a second engagement hole 17 are formed on the opposing surfaces of each tube 15.

[0011] [Band] As shown in FIG. 1, the band 3 includes a plurality of metal pieces 4 constituting the band body and an end piece 5 constituting the end member. The piece 4 is composed of an outer piece 4A and a middle piece 4B, and the end piece 5 is connected to the end of the band body composed of a plurality of pieces 4 and attached to the tube 15. Note that FIG. 1 shows a part of the band 3 attached to the tube 15 at the 6 o'clock direction of the clock 1.

[0012] [End Piece] FIG. 2 is an exploded perspective view of the end piece 5 seen from the back side, and FIG. 3 is a cross-sectional view of the end piece 5 cut along a plane orthogonal to the Y-axis direction which is the width direction of the band 3. As shown in Fig. 2, the end piece 5 includes a housing 20, a first pin member 30, a second pin member 40, an operating member 50, and a pressing plate 60.

[0013] [Housing] As shown in Figs. 2 and 3, the housing 20 includes a base portion 21, a connecting portion 22, and an engaging portion 23. As shown in Fig. 1, the base portion 21 is a substantially plate - shaped portion that is exposed on the front - side of the housing 20 on the surface of the band 3. The connecting portion 22 is provided at the end of the base portion 21 on the side of the piece 4, and includes a pair of guide walls 221 facing each other in the width direction of the band 3 and a connecting wall 222 connecting between the guide walls 221. It is formed in a substantially U - shape in a plan view when the housing 20 is viewed from the back - side. A through - hole 223 penetrating in the Y - axis direction is formed in each guide wall 221. This guide wall 221 is disposed between the outer pieces 4A, and as shown in Fig. 1, the band main body composed of the outer pieces 4A, that is, a plurality of pieces 4, is connected to the connecting portion 22 by screws 224 inserted through the outer pieces 4A and the through - holes 223.

[0014] As shown in Figs. 2 and 3, the engaging portion 23 is provided on the side of the base portion 21 toward the timepiece case 10, and abuts against a corner portion formed by the side surface 12 of the body 11 and the lower surface 13 formed in a direction orthogonal to the side surface 12. That is, the engaging portion 23 includes a first engaging surface 231 that engages with the side surface 12 and a second engaging surface 232 that engages with the lower surface 13. Furthermore, the engaging portion 23 includes a wall surface rising in the Z - axis direction from the base portion 21. This wall surface is located at the center in the Y - axis direction in the engaging portion 23, and includes a contact surface 235 facing the connecting wall 222 of the connecting portion 22, a pair of inclined surfaces 236 provided on both sides of the contact surface 235 and inclined with respect to the X - axis direction and the Y - axis direction, and a pair of flat surfaces 237 provided outside the inclined surfaces 236 and along the Y - axis direction.

[0015] The base portion 21 is formed with a pair of guide pins 24 that project toward the back surface side of the end piece 5. The pair of guide pins 24 are provided at positions outside the connecting portion 22 in the width direction of the housing 20. Also, between the guide pins 24, a pair of screw holes 25 into which a screw 68 (to be described later) is screwed are formed. The screw holes 25 are formed so as not to penetrate the base portion 21 and not to open on the surface of the end piece 5.

[0016] In the recess surrounded by the base portion 21, the connecting portion 22, and the engaging portion 23 of the housing 20, a first pin member 30, a second pin member 40, and an operation member 50 are arranged. The first pin member 30 and the second pin member 40 are arranged apart from each other in the Y-axis direction of the housing 20, and the operation member 50 is arranged therebetween.

[0017] [First Pin Member and Second Pin Member] The first pin member 30 and the second pin member 40 are block-shaped members that are substantially pentagonal in plan view as viewed from the Z-axis direction. The first pin member 30 includes an outer surface 31, a first inclined surface 32, a first contact inclined surface 33, a first contact flat surface 34, a first pin 35, a guide hole 36, and a fixing hole 37. The outer surface 31 is a surface that is exposed on the side surface of the end piece 5, and the first pin 35 projects from the outer surface 31 in the Y-axis direction. The first inclined surface 32 is a surface that faces the operation member 50 and is inclined with respect to the X-axis direction and the Y-axis direction. The first inclined surface 32 is an inclined surface that faces the engaging portion 23 side as it goes from the proximal end side close to the outer surface 31 toward the distal end side away from the outer surface 31, that is, toward the center in the width direction of the band 3. The first contact inclined surface 33 is a surface that faces the inclined surface 236 of the engaging portion 23, and the first contact flat surface 34 is a surface that faces the flat surface 237 of the engaging portion 23. Note that the first contact inclined surface 33 has an inclination direction different from that of the first inclined surface 32. For this reason, the first pin member 30 has a shape in which the dimension between the first inclined surface 32 and the first contact inclined surface 33 becomes smaller, that is, tapers, as it goes toward the distal end side away from the outer surface 31. As shown in Fig. 4, the guide hole 36 is an elongated hole formed in an arc shape in a plan view seen from the Z-axis direction, and is provided so as to penetrate the first pin member 30 in the Z-axis direction. This guide hole 36 is formed in an arc shape between a position close to the outer surface 31 and a position close to the first contact plane 34. At a position close to the first contact plane 34, it has an inclination angle close to the X-axis direction in the plan view, and as it approaches the outer surface 31, that is, as it goes toward the outer side in the width direction of the band 3, it has an inclination angle close to the Y-axis direction. For this reason, the guide hole 36 has a large inclination angle for displacement in the X-axis direction, which is the longitudinal direction of the band 3, with respect to displacement in the Y-axis direction, which is the width direction of the band 3, on the first contact plane 34 side, that is, the center side in the width direction of the band 3. And the guide hole 36 gradually changes to a large inclination angle for displacement in the width direction of the band 3 with respect to displacement in the longitudinal direction of the band 3 as it approaches the outer side in the width direction of the band 3, that is, as it approaches the outer surface 31. The fixing hole 37 is an elongated hole inclined with respect to the X-axis direction and the Y-axis direction in the plan view, and like the guide hole 36, is provided so as to penetrate the first pin member 30. Note that the inclination angle of the fixing hole 37 is approximately the same angle as the end side on the outer surface 31 side of the guide hole 36, that is, an angle close to the Y-axis.

[0018] The second pin member 40 is the same component as the first pin member 30, and is arranged in a direction that is line-symmetrical with respect to the axis along the X-axis direction passing through the center in the width direction of the band 3, that is, in a direction obtained by rotating the first pin member 30 180 degrees with the Z-axis as the rotation axis. That is, the second pin member 40 includes an outer surface 41, a second inclined surface 42, a second contact inclined surface 43, a second contact plane 44, a second pin 45, a guide hole 46, and a fixing hole 47, and these are respectively the same configuration as the outer surface 31, the first inclined surface 32, the first contact inclined surface 33, the first contact plane 34, the first pin 35, the guide hole 36, and the fixing hole 37 of the first pin member 30. For this reason, the description of the specific configuration of the second pin member 40 is omitted.

[0019] In the guide holes 36 and 46 of the first pin member 30 and the second pin member 40, a guide pin 24 and a spring 71 as a biasing member are respectively inserted. The spring 71 is a compression coil spring and is disposed between the end portions on the side of the first contact plane 34 and the second contact plane 44 of the guide holes 36, 46 and the guide pin 24. By this spring 71, the respective pin members 30, 40 are biased in a direction approaching each other. In the fixing holes 37 and 47 of the first pin member 30 and the second pin member 40, screws 68 are inserted. The width dimensions of the fixing holes 37 and 47 are larger than the outer diameter of the screws 68, and the respective pin members 30, 40 having the fixing holes 37, 47 with respect to the screws 68 are provided so as to be slidable. The first pin member 30 and the second pin member 40 are guided by the guide pin 24 and the screw 68 and are slidable in the X-axis direction and the Y-axis direction within the housing 20. That is, each of the pin members 30, 40 moves along the inclination directions of the guide holes 36, 46 and the fixing holes 37, 47. At this time, when each of the pin members 30, 40 moves in a direction approaching each other in the Y-axis direction, it moves toward the engaging portion 23 side in the X-axis direction, and when it moves in a direction away from each other in the Y-axis direction, it moves toward the connecting portion 22 side in the X-axis direction. Here, as shown in FIG. 4, a position where each of the pin members 30, 40 moves in a direction away from each other and the first pin 35 and the second pin 45 engage with the first engaging hole 16 and the second engaging hole 17 is defined as an engaging position. Also, as shown in FIG. 5, a position where each of the pin members 30, 40 moves in a direction approaching each other and the first pin 35 and the second pin 45 disengage from the first engaging hole 16 and the second engaging hole 17 is defined as a release position. As shown in FIG. 5, when each of the pin members 30, 40 moves to the release position, the first contact slope 33 and the second contact slope 43 contact a pair of slopes 236, and the first contact plane 34 and the second contact plane 44 contact a pair of planes 237.

[0020] As shown in FIGS. 2 to 4, the operation member 50 includes a base plate portion 51, a button portion 52, a locking wall portion 53, a first guide surface 54, a second guide surface 55, a contact surface 56, and a holding groove 57. The operation member 50 is disposed between a pair of guide walls 221 and is disposed so as to be movable in the X-axis direction along the guide walls 221. The base plate portion 51 is a flat plate portion having a hexagonal shape in a plan view as viewed from the Z-axis direction, and both side surfaces are in contact with and guided by the guide walls 221. The button portion 52 is provided so as to project from the back surface side of the end piece 5, that is, in the Z-axis direction, from the base plate portion 51. As will be described later, the button portion 52 is an operation portion that is operated by the user of the timepiece 1 when attaching / detaching the end piece 5 from the timepiece case 10. The locking wall portion 53 is a wall portion that projects in the Z-axis direction from the end portion on the engaging portion 23 side of the base plate portion 51. The first guide surface 54 is a surface that faces the first inclined surface 32 of the first pin member 30 on the side surface of the base plate portion 51. The second guide surface 55 is a surface that faces the second inclined surface 42 of the second pin member 40 on the side surface of the base plate portion 51. For this reason, the first guide surface 54 and the second guide surface 55 are inclined in a direction approaching each other in the X-axis direction from the connecting portion 22 side toward the engaging portion 23 side. The contact surface 56 is a surface that faces the contact surface 235 on the side surface of the base plate portion 51. The holding groove 57 is a groove along the X-axis direction on the bottom surface on the base portion 21 side of the base plate portion 51, and two holding grooves 57 are formed in the present embodiment.

[0021] Here, since each of the pin members 30 and 40 is biased by the spring 71, the first inclined surface 32 of the first pin member 30 is always in contact with the first guide surface 54 of the operation member 50, and the second inclined surface 42 of the second pin member 40 is always in contact with the second guide surface 55 of the operation member 50. Therefore, as shown in FIG. 4, when the operating member 50 is moved toward the engaging portion 23 and the contact surface 56 is in contact with the contact surface 235, the first guide surface 54 and the second guide surface 55 are in contact with the tip sides of the first inclined surface 32 and the second inclined surface 42, and the first pin member 30 and the second pin member 40 move in a direction away from each other against the biasing force of the spring 71, that is, to an engaging position where the first pin 35 and the second pin 45 are engaged with the first engaging hole 16 and the second engaging hole 17. On the other hand, as shown in FIG. 5, when the operating member 50 is moved toward the connecting portion 22 and the operating member 50 is in contact with the connecting wall 222, the first guide surface 54 and the second guide surface 55 are in contact with the base end sides of the first inclined surface 32 and the second inclined surface 42, and the first pin member 30 and the second pin member 40 move in a direction approaching each other by the biasing force of the spring 71, that is, to a release position where the first pin 35 and the second pin 45 are disengaged from the first engaging hole 16 and the second engaging hole 17. Here, the position where the operating member 50 is moved toward the engaging portion 23, that is, the position of the operating member 50 where the first pin member 30 and the second pin member 40 are in the engaging position is defined as the first position. Further, the position where the operating member 50 is moved toward the connecting portion 22, that is, the position of the operating member 50 where the first pin member 30 and the second pin member 40 are in the release position is defined as the second position.

[0022] As shown in FIGS. 2 to 4, springs 72 are respectively disposed in the holding grooves 57 of the operating member 50. The spring 72 is a compression coil spring, and is disposed between the base portion 21 and the holding groove 57, and biases the operating member 50 in the Z-axis direction toward the back surface side of the end piece 5, that is, in a direction away from the base portion 21. Therefore, the spring 72 constitutes a second biasing member.

[0023] The pressing plate 60 includes a lid portion 61 and a pair of holding portions 62 extending from both sides in the width direction of the band 3 from the lid portion 61. The cover portion 61 is disposed across the connecting portion 22 and the engaging portion 23, and is formed with an operation hole 63 where the button portion 52 is disposed and a screw hole 64 where the screw 68 is disposed. By screwing the screw 68 disposed in the screw hole 64 into the screw hole 25 through the fixing holes 37, 47 of the pin members 30, 40, the pressing plate 60 is fixed to the housing 20. The base plate portion 51 of the operation member 50 is sandwiched and held between the housing 20 and the pressing plate 60, and the button portion 52 is disposed in the operation hole 63. Further, the holding portion 62 is disposed on the back side of each of the pin members 30, 40. For this reason, each of the pin members 30, 40 is disposed sandwiched between the housing 20 and the holding portion 62. As shown in FIG. 3, a concave portion 65 in which the locking wall portion 53 can be disposed is formed on the surface of the cover portion 61 on the operation member 50 side. In the pressing plate 60, a locking portion 66 is formed between the concave portion 65 and the operation hole 63, and in a state where the locking wall portion 53 is disposed in the concave portion 65, that is, in a state where the operation member 50 is located at the first position, the movement of the operation member 50 to the second position is restricted. Therefore, the locking wall portion 53 of the operation member 50 constitutes a movement restricting portion.

[0024] [Procedure for attaching and detaching the end piece] Next, an operation for attaching and detaching the end piece 5 of the band 3 to and from the watch case 10 will be described. [Procedure for attaching the end piece] When attaching the end piece 5 to the watch case 10, as shown in FIG. 5, the operation member 50 is moved to the position on the connecting portion 22 side, that is, the second position. In this case, as shown in FIG. 6, the operation member 50 is disposed at a position where the locking wall portion 53 abuts against the locking portion 66 and the spring 72 is pushed in and approaches the base portion 21. In this state, as shown in FIG. 5, each of the pin members 30, 40 has moved to a release position where the first pin 35 and the second pin 45 are retracted from the side surface of the housing 20. For this reason, the user can dispose the end piece 5 between the cans 15. Then, the user disposes the end piece 5 at a position where the first engaging surface 231 and the second engaging surface 232 of the engaging portion 23 abut against the side surface 12 and the bottom surface 13 of the watch case 10.

[0025] Next, the user operates the button portion 52 within the operation hole 63 to move the operation member 50 toward the engaging portion 23 side, that is, to the first position. Then, as shown in FIGS. 3 and 4, each pin member 30, 40 moves in a direction away from each other against the biasing force of the spring 71, and the first pin 35 and the second pin 45 move to an engaging position where they engage with the first engaging hole 16 and the second engaging hole 17. Also, as each pin member 30, 40 moves, the guide pin 24 is guided by the guide holes 36, 46 and moves away from the end portions on the outer surface 31, 41 sides of the guide holes 36, 46, and moves toward the clock case 10 side in the X-axis direction. That is, the housing 20 having the guide pin 24 is pushed toward the clock case 10 side with respect to each pin member 30, 40, and the housing 20 of the end piece 5 is pressed against the clock case 10, preventing the generation of gaps or rattling between the end piece 5 and the clock case 10, and improving the appearance.

[0026] Also, when the hand is released from the button portion 52 at the first position where the operation member 50 is in contact with the contact surface 235, as shown in FIG. 3, the operation member 50 is moved to the back surface side by the spring 72, and the locking wall portion 53 engages with the concave portion 65. In this state, the locking wall portion 53 is locked by the locking portion 66, and the movement of the operation member 50 toward the connecting portion 22 side is also restricted. Therefore, the state in which the first pin 35 and the second pin 45 engage with the first engaging hole 16 and the second engaging hole 17 can be reliably maintained.

[0027] [Procedure for Removing the End Piece] Next, a procedure for removing the end piece 5 from the clock case 10 will be described. From the attached state shown in FIGS. 3 and 4, the button portion 52 is pushed in to disengage the locking wall portion 53 from the concave portion 65, and further, the button portion 52 is moved toward the connecting portion 22 side, that is, to the second position. Then, as shown in FIGS. 5 and 6, each pin member 30, 40 is biased by the spring 71 and moves in a direction approaching each other, and each pin member 30, 40 moves to a release position where the first pin 35 and the second pin 45 disengage from the first engaging hole 16 and the second engaging hole 17. Thereby, the end piece 5 can be removed from the clock case 10.

[0028] [Operational Effects of the First Embodiment] By the user operating the operating member 50, the end piece 5 can be attached to and detached from the watch case 10. Then, by inclining the guide holes 36, 46 and the fixing holes 37, 47 formed in the respective pin members 30, 40 with respect to the Y-axis direction in which the first pin 35 and the second pin 45 extend, when each pin member 30, 40 is moved toward the can 15 side and the end piece 5 is attached to the watch case 10, the housing 20 can be pressed against the body 11 of the watch case 10. Thereby, it is possible to prevent the occurrence of a gap or rattling between the end piece 5 and the watch case 10, and the appearance can be improved.

[0029] When the operating member 50 is advanced and retracted in the longitudinal direction of the band 3, since the first guide surface 54 and the second guide surface 55 inclined with respect to the width direction and the longitudinal direction of the band 3 are in contact with the first inclined surface 32 and the second inclined surface 42 by the spring 71, each pin member 30, 40 can be moved in the width direction of the band 3. For this reason, a structure for moving each pin member 30, 40 in conjunction with the operation of the operating member 50 can be realized with a simple configuration and the number of parts can be reduced, so that a structure suitable for the band 3 of the watch 1 can be realized at low cost.

[0030] The guide holes 36, 46 and the guide pins 24 constitute a guide portion for guiding the first pin member 30 and the second pin member 40 so as to be movable between the engagement position and the release position, and since it can be realized with a simple structure and in a space-saving manner, a structure suitable for the band of the watch 1 can be realized at low cost. Since the guide holes 36, 46 are arc-shaped, it is easy to insert the first pin 35 and the second pin 45 of each pin member 30, 40 into the first engagement hole 16 and the second engagement hole 17, and after the first pin 35 and the second pin 45 are engaged with the first engagement hole 16 and the second engagement hole 17, the force for pressing the housing 20 against the watch case 10 can be increased.

[0031] Each pin member 30, 40 and the operating member 50 can be surely held by the housing 20 and the pressing plate 60, and it is possible to prevent each pin member 30, 40 and the operating member 50 from being exposed to the outside, resulting in a simple appearance and improved appearance quality.

[0032] [Second Embodiment] The second embodiment of the present disclosure will be described with reference to FIGS. 7 to 10. The second embodiment is different from the first embodiment in the configuration of the end piece 5B. As shown in FIG. 7, the end piece 5B includes a housing 20B, a first pin member 30B, a second pin member 40B, and an operation member 80B.

[0033] The housing 20B is different from the housing 20 of the first embodiment in the shapes of both ends of the engaging portion 23, but has the same configuration otherwise, so the same reference numerals are used and the description is omitted. The first pin member 30B and the second pin member 40B are different from the first pin member 30 and the second pin member 40 of the first embodiment in that their thickness dimensions are smaller, but have the same configuration otherwise, so the same reference numerals are used and the description is omitted. Also, similar to the first embodiment, springs 71 for biasing the first pin member 30B and the second pin member 40B in a direction approaching each other are respectively disposed on the first pin member 30B and the second pin member 40B.

[0034] As shown in FIGS. 7 and 8, the operation member 80B has a structure in which the operation member 50 and the pressing plate 60 of the first embodiment are integrated. That is, the operation member 80B includes an operation plate portion 81, a pair of pressing plate portions 82, a pair of long holes 83 formed in each pressing plate portion 82, and an operation main body portion 90 integrally formed on the surface of the operation plate portion 81 on the base portion 21 side. The operation plate portion 81 is engraved with the characters "PULL" and is the portion where the user performs a sliding operation. The pair of pressing plate portions 82 respectively extend from the left and right ends of the operation plate portion 81 and cover the first pin member 30B and the second pin member 40B, respectively. Further, the end surface of the pressing plate portion 82 on the clock case 10 side is shaped to be able to contact the contact surface 235, the inclined surface 236, and the flat surface 237 of the engaging portion 23. The pair of elongated holes 83 are holes extended along the X-axis direction and are formed through the pressing plate portion 82. Screws 68 are respectively disposed in each of the elongated holes 83, and the operation member 80B is disposed movably in the X-axis direction.

[0035] As shown in FIG. 8, the operation main body portion 90 includes a first guide surface 91, a second guide surface 92, a contact surface 93, and a holding groove 94. The operation main body portion 90 is disposed between the pair of guide walls 221 and is disposed movably in the X-axis direction along the guide walls 221. The first guide surface 91 is a guide surface similar to the first guide surface 54, and is a surface facing the first inclined surface 32 of the first pin member 30B on the side surface of the operation main body portion 90. The second guide surface 92 is a guide surface similar to the second guide surface 55, and is a surface facing the second inclined surface 42 of the second pin member 40B on the side surface of the operation main body portion 90. Therefore, the first guide surface 91 and the second guide surface 92 are inclined in a direction approaching each other in the X-axis direction from the connecting portion 22 side toward the engaging portion 23 side. The contact surface 93 is a surface facing the contact surface 235 on the side surface of the operation main body portion 90. The holding groove 94 is a groove along the X-axis direction that opens to the bottom surface on the base portion 21 side and the connecting portion 22 side in the operation main body portion 90. A spring 95, which is a third biasing member, is disposed in the holding groove 94. The spring 95 is a compression coil spring and is disposed between the connecting wall 222 to bias the operation member 80B toward the engaging portion 23 side. Note that the biasing force of the spring 95 is preferably a biasing force that can move the operation member 80B to the first position, that is, a direction in which the pin members 30 and 40 are separated from each other. For example, the biasing force may be greater than the total biasing force of the two springs 71.

[0036] [Endpiece attachment / detachment operation procedure] In the end piece 5B of the second embodiment, as shown in FIG. 9, when the user operates the operation plate portion 81 of the operation member 80B and slides the operation member 80B in the direction indicated by "PULL", that is, in the direction of the piece 4 side of the band 3, and moves it to the second position, the contact positions of the first guide surface 91 and the second guide surface 92 of the operation main body portion 90 move to the proximal end sides of the first inclined surface 32 and the second inclined surface 42 of the first pin member 30B and the second pin member 40B. For this reason, the first pin member 30B and the second pin member 40B move in a direction approaching each other by the biasing force of the spring 71, and the first pin 35 and the second pin 45 move to the release position where they are disengaged from the first engagement hole 16 and the second engagement hole 17. Therefore, the user can remove the end piece 5B from the watch case 10.

[0037] On the other hand, when attaching the end piece 5B to the watch case 10, as shown in FIG. 9, slide the operation plate portion 81 toward the piece 4 side of the band 3 to move the operation member 80B to the second position, and place the end piece 5B between the lugs 15 in a state where the first pin 35 and the second pin 45 do not protrude from the side surface of the end piece 5B. Next, when the user releases the hand from the operation plate portion 81, the operation member 80B moves toward the watch case 10 by the biasing force of the spring 95. At this time, the user may move the operation plate portion 81 toward the watch case 10 by the user's operation. When the operation member 80B moves to the first position on the side of the watch case 10, as shown in FIG. 10, the contact positions of the first guide surface 91 and the second guide surface 92 of the operation main body portion 90 move to the distal end sides of the first inclined surface 32 and the second inclined surface 42 of the first pin member 30B and the second pin member 40B. For this reason, the first pin member 30B and the second pin member 40B move in a direction away from each other, and the first pin 35 and the second pin 45 move to the engagement position where they engage with the first engagement hole 16 and the second engagement hole 17. Therefore, the end piece 5B can be attached to the watch case 10.

[0038] [Operation and Effect of the Second Embodiment] According to the operation member 80B of the second embodiment, the same operation and effect as those of the first embodiment can be achieved. Furthermore, since the operation member 80B has a pressing plate portion 82 that holds each pin member 30B, 40B between the housing 20B, the number of parts can be reduced compared to the first embodiment. In addition, the operation member 80B with the integral pressing plate portion 82 can be made larger in size than the operation member 50, and since the whole of it is exposed on the back surface of the end piece 5B, the operability of the user can be improved.

[0039] [Modification Example] Note that the present disclosure is not limited to the above-described embodiments, and modifications, improvements, etc. within the scope that can achieve the object of the present disclosure are included in the present disclosure. For example, the configurations of the first pin members 30, 30B and the second pin members 40, 40B are not limited to the configurations of the above-described embodiments. For example, as shown in FIG. 11, a first pin member 30C and a second pin member 40C having guide holes 36C, 46C with the direction of the arc reversed and fixing holes 37C, 47C having an inclination angle corresponding to the guide holes 36C, 46C may be used. The guide holes 36C, 46C have an inclination angle such that the displacement in the X-axis direction, which is the longitudinal direction of the band 3, is small with respect to the displacement in the Y-axis direction, which is the width direction of the band 3, on the center side in the width direction of the band 3, and gradually changes to an inclination angle such that the displacement in the width direction of the band 3 is small with respect to the displacement in the longitudinal direction of the band 3 as it approaches the outer side of the band 3, that is, the outer surfaces 31, 41. The inclination angles of the fixing holes 37C, 47C are set to be approximately the same as the angle on the end side on the outer surface 31 side of the guide holes 36C, 46C. By using such a first pin member 30C and a second pin member 40C, the design variations can be expanded.

[0040] Also, as shown in FIG. 12, a first pin member 30D and a second pin member 40D having linear guide holes 36D, 46D and fixing holes 37D, 47D may be used. Such first pin members 30D and second pin members 40D can reduce the cost because the guide holes 36D, 46D are easier to machine than when they are machined into an arc shape. Furthermore, the guide holes may combine a straight line and an arc. That is, as shown in FIGS. 4 and 5, since the range in which the guide pin 24 moves within the guide holes 36 and 46 is a part, the range in which the guide pin 24 moves may be formed in an arc shape, and the portions where the other springs 71 are arranged may be formed in a straight line shape.

[0041] In each of the above embodiments, the guide pins 24 are provided on the housings 20 and 20B, and the guide holes 36 and 46 are formed in the first pin members 30 and 30B and the second pin members 40 and 40B. However, a guide groove may be formed in the base portion 21 of the housings 20 and 20B, and guide pins guided by the guide groove may be provided on the first pin members 30 and 30B and the second pin members 40 and 40B. Furthermore, guide grooves may also be formed in the pressing plate 60 and the operation member 80B, and guide pins may be provided on both sides of the first pin members 30 and 30B and the second pin members 40 and 40B.

[0042] In the end piece 5 of the first embodiment, the operation member 50 was moved toward the clock case 10 by the user's operation. However, a spring that biases the operation member 50 toward the clock case 10 may be provided as in the second embodiment, and it may move by the biasing force of the spring. At this time, a compression coil spring may be disposed between the operation member 50 and the connecting portion 22 to bias the operation member 50 toward the clock case 10, or a tension coil spring may be disposed between the operation member 50 and the engaging portion 23 to pull the operation member 50 toward the clock case 10. Also, a tension coil spring may be disposed between the first pin members 30 and 30B and the second pin members 40 and 40B.

[0043] The end member of the band 3 is not limited to the end pieces 5 and 5B. For example, in a band without an end piece, a piece provided at the end of the band 3 may be used instead of the end piece. The structure that moves the first pin member and the second pin member in conjunction with the movement of the operation member is not limited to the structure of the above embodiment, and may be realized using, for example, a link mechanism or the like. In the first embodiment, the pressing plate 60 was provided, but the pressing plate 60 may not be provided. For example, screws may be inserted into the guide holes 36 and 46 and the fixing holes 37 and 47 of each pin member 30 and 40 and screwed into the housing 20, and the base plate portion 51 of the operation member 50 may be disposed between the base portion 21 of the housing 20 and each pin member 30 and 40 so that the housing 20 can hold each pin member 30 and 40 and the operation member 50 without providing the pressing plate 60.

[0044] [Summary of the Present Disclosure] The band of the present disclosure is a band attached to a watch case having a first engagement hole and a second engagement hole facing each other, and includes a band body and an end member provided at an end of the band body. The end member includes a first pin member having a first pin that engages with the first engagement hole, a second pin member having a second pin that engages with the second engagement hole, and the second pin member is spaced apart from the first pin member in the width direction of the band. An operation member that moves between a first position and a second position, a housing that holds the first pin member, the second pin member, and the operation member, and a guide portion that guides the first pin member and the second pin member to move between an engagement position and a release position with respect to the housing. The housing has an engagement portion that engages with the watch case and a connection portion that is provided apart from the engagement portion in the longitudinal direction of the band and to which the band body is connected. When the operation member moves to the first position, the first pin member and the second pin member move to the engagement position, and when the operation member moves to the second position, the first pin member and the second pin member move to the release position. The engagement position is a position where the first pin and the second pin are located outside the side surface of the housing in the width direction of the band, and is closer to the connection portion than the release position in the longitudinal direction of the band orthogonal to the width direction. The release position is a position where the first pin and the second pin are located inside the side surface of the housing in the width direction of the band, and is closer to the engagement portion than the engagement position in the longitudinal direction. According to the band of the present disclosure, by moving the operating member to the first position, the first pin member and the second pin member can be moved to the engagement position, and by moving to the second position, they can be moved to the release position. Therefore, by the user operating the operating member, the state where each pin member is engaged with each engagement hole of the case and the end member is attached to the case, and the state where each pin member is removed from each engagement hole of the case and the end member can be removed from the case can be switched, and the user of the watch can easily attach and detach the band. Further, when each pin member moves to the engagement position and the release position, it moves in the width direction of the band with respect to the housing, and also moves in the longitudinal direction of the band, that is, the direction approaching the engagement portion of the housing and the direction approaching the connecting portion of the housing. And since the engagement positions of the first pin member and the second pin member are closer to the connecting portion than the release position, when the first pin member and the second pin member move from the release position to the engagement position, they move in a direction away from the watch case with respect to the housing. Therefore, based on the first pin member and the second pin member that engage with the watch case, when the first pin member and the second pin member move from the release position to the engagement position, the housing moves in a direction approaching the watch case with respect to the first pin member and the second pin member. Therefore, a force is applied to the housing of the end member in a direction in which the engaging portion is pressed against the watch case, and even if there are variations in the parts, it is possible to prevent play or gaps from occurring between the housing of the end member and the watch case, and the appearance can also be improved.

[0045] In the band of the present disclosure, it preferably has a biasing member held by the first pin member and the second pin member. The operating member is disposed between the first pin member and the second pin member and has a first guide surface and a second guide surface that are inclined with respect to the width direction and the longitudinal direction of the band. The first pin member has a first inclined surface facing the first guide surface, the second pin member has a second inclined surface facing the second guide surface, and the biasing member preferably abuts the first inclined surface against the first guide surface and the second inclined surface against the second guide surface. According to the band of the present disclosure, when the operating member is advanced and retracted in the longitudinal direction of the band, the first guide surface and the second guide surface inclined with respect to the width direction and the longitudinal direction of the band, and the first inclined surface and the second inclined surface are in contact with each other by the biasing member. Therefore, each pin member can be moved in the width direction of the band. For this reason, a structure for moving each pin member in conjunction with the operation of the operating member can be realized with a simple configuration and the number of parts can be reduced. Thus, a structure suitable for a wristwatch band can be realized at low cost.

[0046] In the band of the present disclosure, the first pin member and the second pin member have guide holes extending in the width direction and the longitudinal direction of the band, the housing has guide pins inserted into the guide holes, and the guide portion is preferably composed of the guide holes and the guide pins. According to the band of the present disclosure, since the guide holes and the guide pins constitute a guide portion for guiding the first pin member and the second pin member movably between the engagement position and the release position, it can be realized with a simple structure and space saving. Therefore, a structure suitable for a wristwatch band can be realized at low cost. Further, since the movement locus of each pin member can be set according to the shape of the guide hole, it is easy to insert the pins of each pin member into the engagement holes of the watch case, and after the pins are engaged with the engagement holes, the force for pressing the housing against the watch case can be increased. The movement locus can be easily set only by the shape of the guide hole.

[0047] In the band of the present disclosure, the guide hole is preferably formed in an arc shape in which the displacement in the width direction of the band is larger than the displacement in the longitudinal direction of the band as it goes toward the outside in the width direction of the band. According to the band of the present disclosure, since the guide hole is formed in an arc shape, and the shape is an arc in which the displacement in the width direction of the band is larger than the displacement in the longitudinal direction of the band as it goes toward the outside in the width direction of the band, it is easy to insert the pins of each pin member into the engagement holes of the watch case, and after the pins are engaged with the engagement holes, the force for pressing the housing against the watch case can be increased.

[0048] In the band of the present disclosure, it preferably has a pressing plate fixed to the housing with screws, and the first pin member, the second pin member, and the operating member are preferably disposed between the housing and the pressing plate. According to the band of the present disclosure, each pin member and the operating member can be reliably held by the housing and the pressing plate. Further, since the pin members and the operating member are disposed between the housing and the pressing plate, it is possible to prevent the pin members and the operating member from being exposed, resulting in a simple appearance and improved aesthetics.

[0049] In the band of the present disclosure, the operating member is biased toward the pressing plate by a second biasing member disposed between the housing and the operating member, and is configured to be movable to the first position and the second position in a state where the operating member is pushed into the housing against the biasing force of the second biasing member. When located at the first position and biased by the second biasing member, it preferably includes a movement restricting portion that engages with the pressing plate to restrict movement to the second position. According to the band of the present disclosure, the user can move to the first position and the second position only when the operating member is pushed in. When the operating member is located at the first position, that is, when each pin member has moved to the engagement position, the movement restricting portion of the operating member engages with the pressing plate by the biasing force of the second biasing member to restrict movement to the second position, that is, to restrict the pin member from moving from the engagement position to the release position. Therefore, in a state where the band is attached to the watch case, the attached state of the band can be reliably maintained unless the user operates the operating member, and when removing, it can be removed with a simple operation by pushing the operating member into the second position.

[0050] In the band of the present disclosure, the operating member has a long hole extending in the longitudinal direction of the band and a pressing plate portion, and is fixed to the housing by a screw disposed in the long hole. The first pin member and the second pin member are preferably disposed between the housing and the pressing plate portion. According to the band of the present disclosure, since the operating member has a pressing plate portion that holds each pin member between the housing, the number of components can be reduced as compared with the case where the operating member and the pressing plate are configured as separate components. Further, since the operating member with the integral pressing plate portion can be made larger in size, the operability for the user can be improved.

[0051] In the band of the present disclosure, it is preferable to include a third biasing member that is disposed between the housing and the operating member and biases the operating member in a direction to move to the first position. According to the band of the present disclosure, if the user moves the operating member to the second position against the biasing force of the third biasing member, each pin member can be moved to the release position. Further, if the user releases the operation of the operating member, the operating member can be maintained in the state of being moved to the first position by the biasing force of the third biasing member, and each pin member can also be maintained in the engaged position. Therefore, the user only needs to operate the operating member only when moving the pin member to the release position, and the attached state of the band can be reliably maintained as long as the user does not operate the operating member.

[0052] The clock of the present invention is characterized by including the band. According to the clock of the present invention, since it includes the above-described band, it exhibits the above-described effects, can reduce the play and gaps between the end portion of the band and the case, and can improve the appearance.

[0053] The watch of the present invention includes a watch case having a first engagement hole and a second engagement hole facing each other, a band body, and a band having an end member provided at an end of the band body and attached to the watch case. The end member includes a first pin member having a first pin engageable with the first engagement hole, a second pin member having a second pin engageable with the second engagement hole and spaced apart from the first pin member in the width direction of the band, an operating member movable to a first position and a second position, and a housing holding the first pin member, the second pin member, and the operating member. The first pin member and the second pin member are provided so as to be movable to an engagement position where they engage with the first engagement hole and the second engagement hole when the operating member is moved to the first position, and to a release position where they do not engage with the first engagement hole and the second engagement hole when moved to the second position. According to the watch of the present invention, by moving the operating member to the first position, the first pin member and the second pin member can be moved to the engagement position, and by moving to the second position, they can be moved to the release position. Therefore, by the user operating the operating member, the state where each pin member engages with each engagement hole of the case to attach the end member to the case and the state where each pin member is removed from each engagement hole of the case to remove the end member from the case can be switched, and the user of the watch can easily attach and detach the band. Further, when each pin member moves to the engagement position and the release position, it moves in the width direction of the band and also moves in the longitudinal direction of the band, that is, in the direction away from the watch case and in the direction approaching the watch case. Since the engagement positions of the first pin member and the second pin member are positions farther from the watch case than the release position, when the first pin member and the second pin member move from the release position to the engagement position, they move in the direction away from the watch case with respect to the housing. Therefore, based on the first pin member and the second pin member that engage with the watch case, when the first pin member and the second pin member move from the release position to the engagement position, the housing moves in the direction approaching the watch case with respect to the first pin member and the second pin member. Therefore, a force is applied to the housing of the end member in the direction of being pressed against the watch case, and even if there are variations in the parts, it is possible to prevent play or gaps from occurring between the housing of the end member and the watch case, and the appearance can also be improved.
