Note that the first pin 123, together with the band holding device 10, constitutes the band holding mechanism 1 of the present disclosure. Furthermore, in the present embodiment, the watch body 110 includes the band holding device 10. Note that the watch body 110 is an example of the list device main body part of the present disclosure.

[0016] [Band holding device] The band holding device 10 is a device for connecting the band 120 to the case 111 of the watch body 110. In the present embodiment, the band holding device 10 includes a holding member 20 and an intermediate member 30.

[0017] [Holding member] The holding member 20 is configured to hold the band 120 by engaging with the first pin 123 of the band 120. In the present embodiment, the holding member 20 includes a holding member main body part 21 and an elastic member 22. The holding member main body part 21 is housed in a housing recess 313 of the intermediate member 30 described later, and is supported by the intermediate member 30 by being fastened to the bottom surface of the housing recess 313 by a fastening member 33. Then, as will be described later, the holding member main body part 21 is configured to be movable between a fixed position and a detachable position with respect to the housing recess 313 of the intermediate member 30. In the present embodiment, the holding member main body part 21 has a contact surface 211 that contacts the first pin 123 inserted into an introduction groove 311 of the intermediate member 30 described later. Further, a hole part 212 through which the fastening member 33 described later is inserted is formed in the holding member main body part 21.

[0018] The elastic member 22 is configured as a so-called coil spring. And the elastic member 22 is housed in the housing recess 313 of the intermediary member 30 described later. More specifically, the elastic member 22 is interposed and housed between the holding member main body portion 21 and the bottom surface of the housing recess 313. Thereby, the elastic member 22 is configured to bias the holding member main body portion 21 toward the back side of the timepiece 100.

[0019] [Intermediary member] The intermediary member 30 supports the holding member 20 and is fixed to the case 111. In the present embodiment, the intermediary member 30 has an intermediary member main body portion 31, a second pin 32, and a fastening member 33.

[0020] The intermediary member main body portion 31 is a metal member, and an introduction groove 311, an insertion hole 312, and a housing recess 313 are formed therein. The introduction groove 311 is a groove into which the first pin 123 of the band 120 described above is inserted. In the present embodiment, the introduction groove 311 is formed so as to open on the back side of the timepiece 100 in the intermediary member main body portion 31. And the introduction groove 311 is formed with an opening 314 and a bottom portion 315. As described above, the opening 314 opens toward the back side of the timepiece 100 in the intermediary member main body portion 31. Note that the opening 314 is an example of the opening of the present disclosure. The bottom portion 315 is provided at the end on the back side of the introduction groove 311.

[0021] The insertion hole 312 is a hole into which the second pin 32 is inserted. In the present embodiment, the insertion hole 312 is formed in the intermediary member main body portion 31 so as to penetrate in the width direction of the intermediary member main body portion 31. The housing recess 313 is formed so as to open on the back side of the timepiece 100 in the intermediary member main body portion 31, similarly to the introduction groove 311. And as described above, the holding member main body portion 21 and the elastic member 22 are housed in the housing recess 313.

[0022] The second pin 32 is configured as a so-called spring rod. It is inserted into the insertion hole 312 of the intermediate member main body 31 and supported by a pair of holding piece portions 112A and 112B of the collar 112. Thereby, the intermediate member 30 is fixed to the case 111. The fastening member 33 is configured as a so-called stepped screw. The fastening member 33 is inserted through the hole portion 212 of the holding member main body 21 and screwed into a screw hole (not shown) formed on the bottom surface of the storage recess 313. Thereby, the fastening member 33 attaches the holding member main body 21 to the storage recess 313. At this time, the fastening member 33 attaches the holding member main body 21 to the storage recess 313 such that the holding member main body 21 can slide within the storage recess 313.

[0023] [Fixing position and attaching / detaching position of the holding member] Next, the fixing position and the attaching / detaching position of the holding member 20 will be described. FIG. 5 is a cross-sectional view showing the fixing position of the holding member 20, and FIG. 6 is a cross-sectional view showing the attaching / detaching position of the holding member 20. First, as shown in FIG. 5, in a normal state, the holding member main body 21 of the holding member 20 is urged by the elastic member 22 and slides within the storage recess 313 toward the back side of the clock 100 in the first direction L1 shown in FIG. 5. In this state, in a cross-sectional view, a part of the opening 314 of the introduction groove 311 is covered by the holding member main body 21. In the present disclosure, the position of the holding member 20 shown in FIG. 5 is referred to as the fixing position.

[0024] When the holding member main body 21 in this state is pressed toward the front side of the clock 100, as shown in FIG. 6, the holding member main body 21 slides within the storage recess 313 toward the front side of the clock 100 in the second direction L2 shown in FIG. 6. In this state, in a cross-sectional view, the opening 314 of the introduction groove 311 is not covered by the holding member main body 21 and opens toward the back side of the clock 100. In the present disclosure, the position of the holding member 20 shown in FIG. 6 is referred to as the attaching / detaching position. Thus, in this embodiment, the holding member main body portion 21 of the holding member 20 is configured to be movable between a fixed position and a detachable position by sliding in the storage recess 313 in the first direction L1 and the second direction L2.

[0025] [Method of attaching and detaching the band] Next, the method of attaching and detaching the band 120 of this embodiment will be described. FIGS. 7 and 8 are cross-sectional views showing a state in which the band 120 is attached to the case 111. First, as shown in FIG. 7, in a state where the first pin 123 of the band 120 is not inserted into the introduction groove 311, that is, in a state where the band 120 is not attached to the watch body 110, by pressing the holding member main body portion 21 in the second direction L2, the holding member main body portion 21 is moved to the detachable position. Then, the first pin 123 is inserted from the opening 314 along the introduction groove 311 toward the bottom 315.

[0026] Then, as shown in FIG. 8, when the pressing of the holding member main body portion 21 is released in a state where the first pin 123 is inserted until it abuts against the bottom 315 of the introduction groove 311, the holding member main body portion 21 is biased by the elastic member 22. Then, the holding member main body portion 21 slides in the first direction L1 and moves to the fixed position as shown in FIG. 4. And, as described above, the opening 314 of the introduction groove 311 is covered by the holding member main body portion 21, and the first pin 123 engages with the holding member main body portion 21. Thereby, the first pin 123 cannot come out of the introduction groove 311 in a state of being engaged with the holding member main body portion 21, so that the band 120 is attached to the watch body 110.

[0027] On the other hand, when removing the band 120 from the watch body 110, from the state shown in FIG. 4, the wearer slides the holding member main body portion 21 in the second direction L2 by pressing the holding member main body portion 21. As a result, the holding member main body portion 21 moves to the detachable position as shown in FIG. 8, so that the first pin 123 can be moved along the introduction groove 311 and pulled out from the opening 314.

[0028] Thus, in this embodiment, since the holding member 20 that holds the band 120 is supported by the intermediate member 30 attached to the case 111, a first pin 123 extending in the width direction may be provided at the end of the band 120. That is, since the member that connects the band 120 and the watch body 110 is attached to the case 111, the member disposed at the end of the band 120 can be miniaturized, and the number of components can be reduced.

[0029] In this embodiment, since the contact surface 211 of the holding member main body 21 is inclined with respect to the insertion direction of the first pin 123, that is, the direction in which the introduction groove 311 opens, the first pin 123 can be inserted into the introduction groove 311 and the band 120 can be attached to the watch body 110 without pressing the holding member main body 21. That is, when the first pin 123 is inserted into the introduction groove 311 with the holding member main body 21 in the fixed position, the first pin 123 abuts against the contact surface 211 of the holding member main body 21. Here, in this embodiment, the contact surface 211 is inclined in the insertion direction of the first pin 123 so that the holding member main body 21 slides in the second direction L2. Therefore, in this state, when the first pin 123 is further inserted toward the bottom 315 of the introduction groove 311, the contact surface 211 is pressed against the first pin 123, and the holding member main body 21 slides in the second direction L2. As a result, since the holding member main body 21 moves to the attachment / detachment position, the wearer can attach the band 120 to the watch body 110 without pressing the holding member main body 21.

[0030] [Operation and Effect of the First Embodiment] According to such a first embodiment, the following effects can be obtained. In this embodiment, since the holding member 20 that holds the band 120 by engaging with the first pin 123 is supported by the intermediate member 30 attached to the case 111, a first pin 123 extending in the width direction may be provided at the end of the band 120. Therefore, the member disposed at the end of the band 120 can be miniaturized, and the number of components can be reduced.

[0031] In this embodiment, by inserting the first pin 123 into the insertion groove 311 provided in the intermediate member 30, the first pin 123 and the holding member 20 can be engaged, so that the band 120 can be easily attached to the case 111.

[0032] In this embodiment, by moving the holding member 20 between the fixed position and the detachable position, the first pin 123 can be engaged with the holding member 20 or the first pin 123 can be removed from the insertion groove 311, so that the band 120 can be easily attached to and detached from the case 111.

[0033] In this embodiment, since the contact surface 211 of the holding member 20 is inclined with respect to the insertion direction of the first pin 123, the first pin 123 can be inserted into the insertion groove without operating the holding member 20, and the first pin 123 and the holding member 20 can be engaged. Therefore, the attachment operation of the band 120 can be facilitated.

[0034] [Second Embodiment] Next, the timepiece 100A according to the second embodiment of the present invention will be described with reference to FIGS. 9 to 14. The band holding device 10A of the second embodiment is different from the first embodiment in that the holding member 20A is rotatably supported by the intermediate member 30A. In the second embodiment, the same or similar components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

[0035] FIG. 9 is an exploded perspective view showing a schematic of a main part of the band holding mechanism 1A according to the second embodiment, and FIG. 10 is a cross-sectional view showing the main part of the band holding mechanism 1A. As shown in FIGS. 9 and 10, the band 120 is provided at the engaging side end with the case 111 in the same manner as in the first embodiment described above, and has a first pin 123 extending in the width direction. The first pin 123, together with the band holding device 10A, constitutes the band holding mechanism 1A of the present disclosure.

[0036] [Band Holding Device] The band holding device 10A is a device for connecting the band 120 to the case 111 of the watch body 110A. In the present embodiment, the band holding device 10A includes a holding member 20A and an intermediate member 30A.

[0037] [Holding member] Similar to the first embodiment described above, the holding member 20A is configured to hold the band 120 by engaging with the first pin 123 of the band 120. In the present embodiment, the holding member 20A has a holding member main body portion 21A and an elastic member 22A. The holding member main body portion 21A is rotatably supported by the intermediate member 30A by being supported by the spring rod 32A of the intermediate member 30A described later. And, as will be described later, the holding member main body portion 21A is configured to be movable between a fixed position and a detachment position. In the present embodiment, the holding member main body portion 21A has a contact surface 211A that contacts the first pin 123 inserted into the introduction groove 311A of the intermediate member 30A described later. Further, the holding member main body portion 21A is provided with a hole portion 212A through which the spring rod 32A described later is inserted, an engaging portion 213A that engages with the first pin 123, and an operation portion 214A for the wearer to operate.

[0038] The elastic member 22A is configured as a so-called torsion coil spring, one end of the coil is locked to the intermediate member 30A, and the other end is attached to the holding member main body portion 21A. And, in the present embodiment, the elastic member 22A is configured to urge the holding member main body portion 21A so as to rotate in a direction in which the engaging portion 213A of the holding member main body portion 21A moves away from the case 111.

[0039] [Intermediate member] The intermediate member 30A supports the holding member 20A and is fixed to the case 111. In the present embodiment, the intermediate member 30A has an intermediate member main body portion 31A, a spring rod 32A, and a cylindrical member 33A.

[0040] The intermediate member main body portion 31A is a metal member, and an introduction groove 311A and an insertion hole 312A are formed therein. The introduction groove 311A is a groove into which the first pin 123 of the band 120 is inserted, similar to the first embodiment described above. In this embodiment, the introduction groove 311A is formed so as to open on the back side of the timepiece 100A in the intermediate member main body 31A. And the introduction groove 311A is formed with an opening 314A and a bottom 315A. As described above, the opening 314A opens toward the back side of the timepiece 100A in the intermediate member main body 31A. Note that the opening 314A is an example of the opening of the present disclosure. The bottom 315A is provided at the end on the inner side of the introduction groove 311A.

[0041] The insertion hole 312A is a hole into which the spring rod 32A and the cylindrical member 33A are inserted. In this embodiment, the insertion hole 312A is formed in the intermediate member main body 31A so as to penetrate in the width direction of the intermediate member main body 31A. The spring rod 32A and the cylindrical member 33A are inserted into the hole 212A of the holding member main body 21A and the insertion hole 312A of the intermediate member main body 31A. Specifically, the spring rod 32A is inserted into the inner peripheral side of the cylindrical member 33A, and the spring rod 32A and the cylindrical member 33A in this state are inserted into the insertion hole 312A of the intermediate member main body 31A. Thereby, the holding member main body 21A is rotatably supported by the intermediate member 30A. Further, the spring rod 32A is supported by the pair of holding pieces 112A, 112B of the collar 112. Thereby, the intermediate member 30A is fixed to the case 111.

[0042] Thus, in this embodiment, the spring rod 32A rotatably supports the holding member main body 21A and fixes the intermediate member main body 31A to the case 111. That is, the spring rod 32A constitutes the second pin and the third pin of the present disclosure. Thereby, since the spring rod 32A also serves as the second pin for rotatably supporting the holding member 20A and the third pin for fixing the intermediate member 30A to the case, the number of parts can be reduced.

[0043] [Fixing position and attaching / detaching position of the holding member] Next, the fixed position and the attachment / detachment position of the holding member 20A will be described. FIG. 11 is a cross-sectional view showing the fixed position of the holding member 20A, and FIG. 12 is a cross-sectional view showing the attachment / detachment position of the holding member 20A. First, as shown in FIG. 11, in a normal state, the holding member main body portion 21A of the holding member 20A is urged by the elastic member 22A and rotates in a direction away from the watch body 110A, i.e., in the first direction R1 shown in FIG. 11. In this state, in a cross-sectional view, the opening 314A of the introduction groove 311A is covered by the engaging portion 213A of the holding member main body portion 21A. In the present disclosure, the position of the holding member 20A shown in FIG. 11 is referred to as the fixed position.

[0044] Then, when the operation portion 214A of the holding member main body portion 21A in this state is pressed toward the back surface side of the watch 100A, as shown in FIG. 12, the engaging portion 213A of the holding member main body portion 21A rotates in a direction approaching the watch body 110A, i.e., in the second direction R2 shown in FIG. 12. In this state, in a cross-sectional view, the opening 314A of the introduction groove 311A is not covered by the engaging portion 213A of the holding member main body portion 21A and opens toward the back surface side of the watch 100A. In the present disclosure, the position of the holding member 20A shown in FIG. 12 is referred to as the attachment / detachment position. Thus, in the present embodiment, the holding member main body portion 21A of the holding member 20A is configured to be movable between the fixed position and the attachment / detachment position by rotating in the first direction R1 and the second direction R2.

[0045] [Method of attaching and detaching the band] Next, the method of attaching and detaching the band 120 of the present embodiment will be described. FIGS. 13 and 14 are cross-sectional views showing a state where the band 120 is attached to the case 111. First, as shown in FIG. 13, in a state where the first pin 123 of the band 120 is not inserted into the introduction groove 311A, that is, in a state where the band 120 is not attached to the watch body 110A, the operation portion 214A of the holding member main body portion 21A is pressed in the second direction R2 to move the holding member main body portion 21A to the attachment / detachment position. Then, the first pin 123 is inserted from the opening portion 314A along the introduction groove 311A toward the bottom portion 315A.

[0046] Then, as shown in FIG. 14, in a state where the first pin 123 is inserted until it abuts against the bottom portion 315A of the introduction groove 311A, when the pressing of the operation portion 214A of the holding member main body portion 21A is released, the holding member main body portion 21A is biased by the elastic member 22A. Then, the holding member main body portion 21A rotates in the first direction R1 and moves to the fixed position as shown in FIG. 10. And as described above, the opening portion 314A of the introduction groove 311A is covered by the engaging portion 213A of the holding member main body portion 21A, and the first pin 123 engages with the engaging portion 213A of the holding member main body portion 21A. Thereby, since the first pin 123 cannot come out of the introduction groove 311A in a state of engaging with the engaging portion 213A of the holding member main body portion 21A, the band 120 is attached to the watch body 110A.

[0047] On the other hand, when removing the band 120 from the watch body 110A, from the state shown in FIG. 10, the wearer presses the operation portion 214A of the holding member main body portion 21A to rotate the holding member main body portion 21A in the second direction R2. Thereby, since the holding member main body portion 21A moves to the attachment / detachment position as shown in FIG. 13, the first pin 123 can be moved along the introduction groove 311A and pulled out from the opening portion 314A.

[0048] Thus, in this embodiment, similar to the first embodiment described above, since the holding member 20A that holds the band 120 is supported by the intermediate member 30A attached to the case 111, a first pin 123 extending in the width direction may be provided at the end of the band 120. That is, since the member connecting the band 120 and the watch body 110A is attached to the case 111, the member disposed at the end of the band 120 can be miniaturized, and the number of parts can be reduced. Further, in this embodiment, since the intermediate member 30A has a spring rod 32A that rotatably supports the holding member 20A, the holding member 20A can be rotatably supported at a fixed position and a detachable position.

[0049] Note that, in this embodiment, similar to the first embodiment described above, since the contact surface 211A of the holding member main body portion 21A is inclined with respect to the insertion direction of the first pin 123, that is, the direction in which the introduction groove 311A opens, the first pin 123 can be inserted into the introduction groove 311 without pressing the holding member main body portion 21A, and the band 120 can be attached to the watch body 110A.

[0050] [Operation and Effect of the Second Embodiment] According to such a second embodiment, the following effects can be obtained. In this embodiment, since the intermediate member 30A has a spring rod 32A that rotatably supports the holding member 20A, the holding member 20A can be rotatably supported at a fixed position and a detachable position.

[0051] In this embodiment, since the intermediate member 30A is attached to the case 111 by the spring rod 32A, the intermediate member 30A can be easily fixed to the case 111.

[0052] In this embodiment, the spring rod 32A not only rotatably supports the holding member 20A but also fixes the intermediate member 30A to the case 111, so that the number of parts can be reduced.

[0053] [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. FIG. 15 is a cross-sectional view showing an outline of a main part of a band holding mechanism 1B of a modified example, and FIG. 16 is a rear view showing a main part of a clock 100B of the modified example. As shown in FIGS. 15 and 16, a band holding device 10B constituting the band holding mechanism 1B of the modified example includes a holding member 20B and an intermediate member 30B. The intermediate member 30B includes an intermediate member main body portion 31B, and an engaging portion 213B and an operating portion 214B are provided on the intermediate member main body portion 31B in the same manner as in the second embodiment described above. Further, a lid portion 215B that covers the back surface side of the clock main body 110B in the intermediate member main body portion 31B is provided on the intermediate member main body portion 31B of the modified example. Thereby, since the back surface side of the intermediate member main body portion 31B is covered by the lid portion, it is possible to suppress a part of the first pin 123 or the like from being exposed, and the design property can be enhanced.

[0054] FIG. 17 is a perspective view showing an outline of a main part of a clock 100C of another modified example. In the first and second embodiments described above, the band 120C has a band main body 122C formed by combining a plurality of metal pieces 121, but is not limited thereto. For example, as shown in FIG. 17, the band main body 122C may be formed of leather, cloth, synthetic resin, or the like.

[0055] FIG. 18 is an exploded perspective view showing an outline of a main part of a band holding mechanism 1D of still another modified example. As shown in FIG. 18, a band holding device 10D constituting the band holding mechanism 1D of the modified example of the clock 100D includes a holding member 20D and an intermediate member 30D. The intermediate member main body portion 31D of the intermediate member 30D is provided integrally with the case 111 of the clock main body 110D. Thereby, since a spring bar or the like for attaching the intermediate member main body portion 31D to the case 111 is not required, the number of parts can be reduced.

[0056] In the above-described second embodiment, the spring bar 32A also served as the second pin that supports the holding member 20A and the third pin that fixes the intermediate member 30A to the case 111, but the present invention is not limited to this. For example, the second pin that supports the holding member and the third pin that fixes the intermediate member to the case may be provided separately.

[0057] In each of the above embodiments, the first pin 123 was cylindrical, but the present invention is not limited to this. For example, the first pin may be elliptical columnar or polygonal columnar. By configuring in this way, the attachment angle of the band to the intermediate member can be arbitrarily set. Furthermore, the case where the first pin is cylindrical or polygonal cylindrical is also included in the present disclosure.

[0058] In each of the above embodiments, the watches 100, 100A, 100B, 100C, 100D as the list devices are exemplified, but the present invention is not limited to this. For example, the present disclosure can be applied to list devices such as a pulse meter and a band attached to the list device. Furthermore, as the watches 100, 100A, 100B, 100C, 100D as the list devices, the present invention can be applied to watches worn on the wearer's wrist using a band regardless of whether they are so-called digital watches or analog watches.

[0059] [Summary of the Present Disclosure] The band holding mechanism of the present disclosure includes a band having a first pin extending in the width direction at an engagement side end with a case, a holding member that holds the band by engaging with the first pin, and an intermediate member that supports the holding member and is attached to the case or provided integrally with the case. Thereby, the holding member that holds the band by engaging with the first pin is supported by the intermediate member attached to the case or provided integrally with the case, so that a first pin extending in the width direction may be provided at the end of the band. Therefore, the member disposed at the end of the band can be miniaturized, and the number of components can be reduced.

[0060] In the band holding mechanism of the present disclosure, the intermediate member has an introduction groove into which the first pin can be inserted, and the first pin may engage with the holding member by being inserted into the introduction groove. By inserting the first pin into the introduction groove provided in the intermediate member, the first pin and the holding member can be engaged, so that the band can be easily attached to the case.

[0061] In the band holding mechanism of the present disclosure, the intermediate member may movably support the holding member at a fixed position for fixing the first pin in the introduction groove and a detachable position for detaching the first pin inserted into the introduction groove. Thereby, by moving the holding member between the fixed position and the detachable position, the first pin can be engaged with the holding member or the first pin can be removed from the introduction groove, so that the band can be easily attached to and detached from the case.

[0062] In the band holding mechanism of the present disclosure, the holding member has a contact surface that contacts the first pin inserted into the introduction groove from the opening of the introduction groove, and the contact surface is inclined with respect to the insertion direction of the first pin so that the holding member moves toward the detachable position when the first pin is further inserted into the introduction groove in a state where the first pin and the contact surface are in contact. Thereby, since the contact surface of the holding member is inclined with respect to the insertion direction of the first pin, the first pin can be inserted into the introduction groove without operating the holding member, and the first pin and the holding member can be engaged. Therefore, the attachment operation of the band can be facilitated.

[0063] In the band holding mechanism of the present disclosure, the intermediate member may have a second pin that rotatably supports the holding member. Thereby, the intermediate member can rotatably support the holding member at a fixed position and a detachable position.

[0064] In the band holding mechanism of the present disclosure, the intermediate member may have a third pin for attaching to the case. Thereby, the intermediate member can be easily fixed to the case.

[0065] In the band holding mechanism of the present disclosure, the intermediate member may have spring bars constituting the second pin and the third pin. Thereby, since the spring bar also serves as the second pin that rotatably supports the holding member and the third pin that fixes the intermediate member to the case, the number of parts can be reduced.

[0066] The list device of the present disclosure includes a case, a band having a first pin extending in the width direction at an engaging side end with the case, a holding member that holds the band by engaging with the first pin, and an intermediate member that supports the holding member and is attached to the case or provided integrally with the case.

[0067] The main body part of the list device of the present disclosure includes a case, a holding member that holds the band by engaging with a first pin of the band, and an intermediate member that supports the holding member and is attached to the case or provided integrally with the case.

[0068] The band holding device of the present disclosure includes a holding member that holds the band by engaging with a first pin of the band, and an intermediate member that supports the holding member and is attached to the case or provided integrally with the case.

[0069] The band of the present disclosure has a first pin extending in the width direction at an engaging side end with the case, and is connected to the case by a holding member that engages with the first pin and an intermediate member that supports the holding member and is attached to the case or provided integrally with the case.
