[0036] Furthermore, in the present embodiment, the watch main body 110 includes the strap holding devices 10. The watch main body 110 is an example of a wrist device main body portion of the present disclosure.Strap Holding Devices

[0037] The strap holding devices 10 are devices provided to couple the straps 120 to the case 111 of the watch main body 110. In the present embodiment, the strap holding device 10 includes the holding member 20 and the intermediate member 30.Holding Member

[0038] The holding member 20 is configured to hold the strap 120 by being engaged with the first pin 123 of the strap 120. In the present embodiment, the holding member 20 includes a holding member main body portion 21 and protruding portions 22.

[0039] The holding member main body portion 21 is accommodated in an accommodation recess portion 313 of the intermediate member 30 which will be described later, and is partially exposed on a rear surface side of the watch 100. The protruding portions 22 are provided to protrude from the holding member main body portion 21. Specifically, the protruding portions 22 are provided to protrude in a direction from the rear surface side of the watch 100 to a front surface side of the watch 100, with respect to the holding member main body portion 21. In other words, the protruding portions 22 are provided to protrude in the direction of movement of the holding member 20 which will be described later, with respect to the holding member main body portion 21. The protruding portions 22 are accommodated in accommodation hole portions 316 formed at a bottom surface of the accommodation recess portion 313, which will be described later.

[0040] In addition, the protruding portions 22 are engaged with an attachment member 34 of the intermediate member 30 which will be described later so that the holding member 20 is attached to the intermediate member 30 to be movable in the accommodation recess portion 313. Specifically, the protruding portions 22 include engagement recess portions 221 that are open laterally, and the engagement recess portions 221 are engaged with the attachment member 34 so that the holding member 20 is supported such that the holding member 20 does not fall off the intermediate member 30.Intermediate Member

[0041] The intermediate member 30 supports the holding member 20 and is fixed to the case 111. In the present embodiment, the intermediate member 30 includes an intermediate member main body portion 31, a second pin 32, elastic members 33, and the attachment member 34.

[0042] An introduction groove 311, an insertion hole 312, and the accommodation recess portion 313 are formed at the intermediate member main body portion 31.

[0043] The introduction groove 311 is a groove into which the first pin 123 of the strap 120 described above is inserted. In the present embodiment, the introduction groove 311 is formed to be open on the rear surface side of the watch 100 at the intermediate member main body portion 31. In addition, an opening portion 314 and a bottom portion 315 are formed at the introduction groove 311.

[0044] As described above, the opening portion 314 is open on the rear surface side of the watch 100 at the intermediate member main body portion 31. The opening portion 314 is an example of an opening of the introduction groove 311 of the present disclosure. The bottom portion 315 is provided at an end portion on an inner side of the introduction groove 311.

[0045] The insertion hole 312 is a hole portion into which the second pin 32 is inserted. In the present embodiment, the insertion hole 312 is formed at the intermediate member main body portion 31 to penetrate in a width direction of the intermediate member main body portion 31. In other words, the insertion hole 312 is formed at the intermediate member main body portion 31 such that the insertion hole 312 penetrates in a direction parallel to the first pin 123, that is, a direction orthogonal to a direction from the front surface side of the watch 100 to the rear surface side of the watch 100, in a state where the strap 120 is attached to the case 111.

[0046] As with the introduction groove 311, the accommodation recess portion 313 is formed to be open on the rear surface side of the watch 100 at the intermediate member main body portion 31. In addition, as described above, the holding member main body portion 21 is accommodated in the accommodation recess portion 313, and the protruding portions 22 are accommodated in the accommodation hole portions 316 formed at the bottom surface of the accommodation recess portion 313.

[0047] The second pin 32 is configured as a so-called spring bar. In addition, the second pin 32 is inserted into the insertion hole 312 of the intermediate member main body portion 31 and is supported by the pair of holding piece portions 112A and 112B of the bow 112. Accordingly, the intermediate member 30 is detachably fixed to the case 111.

[0048] The elastic members 33 are configured as so-called coil springs. In addition, the elastic members 33 are accommodated in the accommodation recess portion 313 together with the holding member 20. More specifically, the elastic members 33 are accommodated to be interposed between the holding member main body portion 21 and the bottom surface of the accommodation recess portion 313. Accordingly, the elastic members 33 are configured to urge the holding member main body portion 21 in the direction from the front surface side of the watch 100 to the rear surface side of the watch 100.

[0049] The attachment member 34 is a member for attachment of the holding member 20 to the intermediate member 30.

[0050] In the present embodiment, the attachment member 34 has a tubular shape and is inserted into the insertion hole 312 of the intermediate member 30. The second pin 32 is inserted into the attachment member 34.

[0051] Accordingly, in the present embodiment, since the second pin 32 for attachment of the intermediate member 30 to the case 111 is inserted into the attachment member 34 having the tubular shape, it is not necessary to provide spaces in the intermediate member 30 in which the second pin 32 and the attachment member 34 are respectively disposed. Therefore, the intermediate member 30 can be made compact.Fixation Position and Attachment and Detachment Position of Holding Member

[0052] Next, a fixation position and an attachment and detachment position of the holding member 20 will be described.

[0053] FIG. 6 is a cross-sectional view showing the fixation position of the holding member 20 and FIG. 7 is a cross-sectional view showing the attachment and detachment position of the holding member 20.

[0054] First, as shown in FIG. 6, in a normal state, the holding member main body portion 21 is urged by the elastic members 33 to move in the accommodation recess portion 313 in a first direction L1 toward the rear surface side of the watch 100, the first direction L1 being shown in FIG. 6. In this state, the opening portion 314 of the introduction groove 311 is partially covered by the holding member main body portion 21 as seen in a cross-sectional view. In the present disclosure, the position of the holding member 20 as shown in FIG. 6 will be referred to as the fixation position.

[0055] In addition, when the holding member main body portion 21 in this state is pressed toward the front surface side of the watch 100, as shown in FIG. 7, the holding member main body portion 21 moves in the accommodation recess portion 313 in a second direction L2 toward the front surface side of the watch 100, the second direction L2 being shown in FIG. 7. In this state, the opening portion 314 of the introduction groove 311 is not covered by the holding member main body portion 21 as seen in a cross-sectional view and is open on the rear surface side of the watch 100. In the present disclosure, the position of the holding member 20 as shown in FIG. 7 will be referred to as the attachment and detachment position.

[0056] As described above, in the present embodiment, the holding member main body portion 21 of the holding member 20 is configured to be movable between the fixation position and the attachment and detachment position by moving in the accommodation recess portion 313 in the first direction L1 and the second direction L2.

[0057] Here, as described above, the holding member 20 moves between the fixation position and the attachment and detachment position. In other words, the holding member 20 moves in the accommodation recess portion 313 in the first direction L1 and the second direction L2, that is, toward the front surface side of the watch 100 and the rear surface side of the watch 100.

[0058] In addition, the attachment member 34 is inserted into the insertion hole 312 that penetrates in the direction orthogonal to the direction from the front surface side of the watch 100 to the rear surface side of the watch 100 as described above. That is, the attachment member 34 is disposed in the insertion hole 312 of the intermediate member 30 in a direction intersecting the direction of movement of the holding member 20 between the fixation position and the attachment and detachment position. More specifically, the attachment member 34 is disposed in a direction orthogonal to the direction of movement of the holding member 20 between the fixation position and the attachment and detachment position. In addition, the attachment member 34 is engaged with the engagement recess portions 221 formed at the protruding portions 22 of the holding member 20. Note that the present disclosure is not limited to the above-described configuration and the attachment member 34 may be disposed along a direction inclined with respect to the direction of movement of the holding member 20 between the fixation position and the attachment and detachment position by approximately 80 degrees as long as the attachment member 34 is configured such that the attachment member 34 intersects the direction of movement of the holding member 20 between the fixation position and the attachment and detachment position so that the attachment member 34 can restrain the holding member 20 from falling off the intermediate member 30.

[0059] In this case, the engagement recess portions 221 are formed such that a dimension H of the engagement recess portions 221 in the direction of movement between the fixation position and the attachment and detachment position is larger than a dimension D of the attachment member 34 in the direction of movement, that is, the diameter of the attachment member 34 having the tubular shape. In addition, the engagement recess portions 221 are engaged with the attachment member 34 so that the holding member 20 is attached to the intermediate member 30 to be movable in the direction of movement between the fixation position and the attachment and detachment position. In other words, the holding member 20 is supported to be movable in the accommodation recess portion 313 with respect to the intermediate member 30.

[0060] Accordingly, the holding member 20 can relatively move in the direction of movement with respect to the intermediate member 30 with the attachment member 34 relatively moving in the direction of movement in the engagement recess portions 221 with respect to the holding member 20. Therefore, a structure that supports the holding member 20 to be movable at the intermediate member 30 can be simplified.

[0061] In addition, in the present embodiment, the holding member 20 is not attached to the intermediate member 30 by means of a screw or the like. Therefore, the intermediate member 30 does not need to be provided with a screw hole. Therefore, even when the intermediate member 30 is formed of a material in which it is difficult to form a screw hole like ceramic, a structure that supports the holding member 20 to be movable at the intermediate member 30 can be easily realized.Attachment and Detachment Method for Strap

[0062] Next, an attachment and detachment method for the strap 120 of the present embodiment will be described.

[0063] FIGS. 8 and 9 are cross-sectional views showing a state where the strap 120 is attached to the case 111.

[0064] First, as shown in FIG. 8, in a state where the first pin 123 of the strap 120 is not inserted into the introduction groove 311, that is, in a state where the strap 120 is not attached to the watch main body 110, the holding member main body portion 21 is pressed in the second direction L2 so that the holding member 20 is moved to the attachment and detachment position. Then, the first pin 123 is inserted toward the bottom portion 315 through the opening portion 314, along the introduction groove 311.

[0065] Then, in a state where the first pin 123 is inserted until the first pin 123 abuts against the bottom portion 315 of the introduction groove 311 thereafter as shown in FIG. 9, the holding member main body portion 21 stops being pressed and then the holding member 20 is urged by the elastic members 33. In this case, the holding member 20 moves in the first direction L1 to move to the fixation position as shown in FIG. 4. In addition, the opening portion 314 of the introduction groove 311 is covered by the holding member main body portion 21 as described above and the first pin 123 is engaged with the holding member main body portion 21. Accordingly, the first pin 123 does not fall off the introduction groove 311 in a state of being engaged with the holding member main body portion 21, so that the strap 120 is attached to the watch main body 110.

[0066] That is, in the present embodiment, since the elastic members 33 urge the holding member 20 to the fixation position, the first pin 123 can be made less likely to unintentionally fall off the introduction groove 311 of the intermediate member 30 and the strap can be made less likely to be detached from the intermediate member 30.

[0067] Meanwhile, when the strap 120 is to be removed from the watch main body 110, the wearer presses the holding member main body portion 21 in a state as shown in FIG. 4 to move the holding member 20 in the second direction L2. Accordingly, the holding member main body portion 21 moves to the attachment and detachment position as shown in FIG. 9, so that the first pin 123 can be moved along the introduction groove 311 and pulled out from the opening portion 314.

[0068] As described above, in the present embodiment, the holding member 20 that holds the strap 120 is supported by the intermediate member 30 attached to the case 111. Therefore, an end portion of the strap 120 only needs to be provided with the first pin 123 extending in the width direction. That is, since a member that couples the strap 120 and the watch main body 110 is attached to the case 111, the size of a member disposed at the end portion of the strap 120 can be reduced and the number of components can also be reduced.

[0069] Note that in the present embodiment, since an abutment surface 211 of the holding member main body portion 21 is inclined with respect to the direction of insertion of the first pin 123, that is, a direction in which the introduction groove 311 is open, it is possible to attach the strap 120 to the watch main body 110 by inserting the first pin 123 into the introduction groove 311 without pressing the holding member main body portion 21.

[0070] That is, when the first pin 123 is inserted into the introduction groove 311 in a state where the holding member main body portion 21 is at the fixation position as shown in FIG. 10, the first pin 123 abuts against the abutment surface 211 of the holding member main body portion 21. Here, in the present embodiment, the abutment surface 211 is inclined with respect to the direction of insertion of the first pin 123 so that the holding member main body portion 21 moves in the second direction L2. Therefore, when the first pin 123 is inserted toward the bottom portion 315 of the introduction groove 311 in such a state, the abutment surface 211 is pressed by the first pin 123 and thus the holding member main body portion 21 moves in the second direction L2 as shown in FIG. 11. Accordingly, the holding member 20 moves to the attachment and detachment position. Therefore, the wearer can attach the strap 120 to the watch main body 110 without pressing the holding member main body portion 21.Action and Effect of First Embodiment

[0071] According to the first embodiment, the following effects can be achieved.

[0072] In the present embodiment, since the holding member 20 that holds the strap 120 by being engaged with the first pin 123 is supported by the intermediate member 30 attached to the case 111, an end portion of the strap 120 only needs to be provided with the first pin 123 extending in the width direction. Therefore, the size of a member disposed at the end portion of the strap 120 can be reduced and the number of components can also be reduced.

[0073] In the present embodiment, since the second pin 32 for attachment of the intermediate member 30 to the case 111 is inserted into the attachment member 34 having the tubular shape, it is not necessary to provide spaces in the intermediate member 30 in which the second pin 32 and the attachment member 34 are respectively disposed. Therefore, the intermediate member 30 can be detachably fixed to the case 111 and the intermediate member 30 can be made compact.

[0074] In the present embodiment, the engagement recess portions 221 are formed such that the dimension H of the engagement recess portions 221 in the direction of movement between the fixation position and the attachment and detachment position is larger than the dimension D of the attachment member 34 in the direction of movement. In addition, the engagement recess portions 221 are engaged with the attachment member 34 so that the holding member 20 is attached to the intermediate member 30 to be movable in the direction of movement between the fixation position and the attachment and detachment position.

[0075] Accordingly, the holding member 20 can relatively move in the direction of movement with respect to the intermediate member 30 with the attachment member 34 relatively moving in the direction of movement in the engagement recess portions 221 with respect to the holding member 20. Therefore, a structure that supports the holding member 20 to be movable at the intermediate member 30 can be simplified.

[0076] In the present embodiment, the intermediate member 30 includes the elastic members 33 that are disposed in the accommodation recess portion 313 and that urge the holding member 20 to the fixation position. Accordingly, since the elastic members 33 urge the holding member 20 to the fixation position, the first pin 123 can be made less likely to unintentionally fall off the introduction groove 311 of the intermediate member 30 and the strap can be made less likely to be detached from the intermediate member 30.

[0077] In the present embodiment, the abutment surface 211 of the holding member 20 is inclined with respect to the direction of insertion of the first pin 123. Therefore, it is possible to engage the first pin 123 with the holding member 20 by inserting the first pin 123 into the introduction groove without operating the holding member 20. Therefore, the strap 120 can be easily attached.

[0078] In the present embodiment, the holding member 20 is not attached to the intermediate member 30 by means of a screw or the like. Therefore, the intermediate member 30 does not need to be provided with a screw hole. Therefore, even when the intermediate member 30 is formed of a material in which it is difficult to form a screw hole like ceramic, a structure that supports the holding member 20 to be movable at the intermediate member 30 can be easily realized.Second Embodiment

[0103] In each of the above-described embodiments, the strap 120 includes the strap main body 122 composed of the plurality of metal blocks 121 combined with each other. However, the present disclosure is not limited thereto. For example, as shown in FIG. 16, a strap main body 122B may be formed of leather, cloth, a synthetic resin, or the like.

[0104] In the above-described embodiments, the intermediate members 30 and 30A are attached to the cases 111 and 111A. However, the present disclosure is not limited thereto. For example, an intermediate member may be provided such that an intermediate member main body portion is integrated with a case. In this case, a spring bar or the like for attachment of the intermediate member main body portion to the case is not needed and thus the number of components can be reduced.

[0105] In the above-described embodiments, the first pin 123 has a columnar shape. However, the present disclosure is not limited thereto. For example, a first pin may have an oval columnar shape or a polygonal columnar shape. In the case of such a configuration, any angle can be set as an angle at which a strap is attached to an intermediate member.

[0106] Furthermore, even a case where the first pin has a cylindrical shape or a polygonal tubular shape is also included in the present disclosure.

[0107] In the above-described embodiments, the watches 100, 100A, and 100B are examples of wrist devices. However, the present disclosure is not limited thereto. For example, the present disclosure can be applied to a wrist device such as a pulse rate meter and a strap attached to the wrist device. Furthermore, the watches 100, 100A, and 100B as the wrist devices can be any watch mounted on an arm of a wearer by means of a strap, regardless of whether the watch is a so-called digital watch, an analog watch, or the like.Summary of Present Disclosure

[0108] According to an aspect of the present disclosure, there is provided a strap holding mechanism including: a strap that includes a first pin extending in a width direction, the first pin being provided at an end portion of the strap on a side on which the strap is engaged with a case; a holding member that holds the strap by being engaged with the first pin; and an intermediate member that supports the holding member and that is attached to the case or is provided to be integrated with the case, in which the intermediate member includes an introduction groove into which the first pin is insertable, an accommodation recess portion that accommodates the holding member, and an attachment member that attaches the holding member to the accommodation recess portion to be movable between a fixation position at which the holding member fixes the first pin to the introduction groove and an attachment and detachment position at which the holding member enables removal of the first pin inserted into the introduction groove, the first pin is engaged with the holding member when the first pin is inserted into the introduction groove, and the attachment member is disposed with respect to the intermediate member in a direction intersecting a direction of movement of the holding member between the fixation position and the attachment and detachment position.

[0109] Accordingly, since the holding member that holds the strap by being engaged with the first pin is supported by the intermediate member that is attached to the case or is provided to be integrated with the case, the end portion of the strap only needs to be provided with the first pin extending in the width direction. Therefore, the size of a member disposed at the end portion of the strap can be reduced and the number of components can also be reduced.

[0110] The strap holding mechanism of the present disclosure may further include a second pin that attaches the intermediate member and the case, an insertion hole into which the second pin is inserted may be formed at the intermediate member, the attachment member may be a tubular member inserted into the insertion hole, and the second pin may be inserted into the attachment member.

[0111] Accordingly, since the second pin for attachment of the intermediate member to the case is inserted into the attachment member having the tubular shape, it is not necessary to provide spaces in the intermediate member in which the second pin and the attachment member are respectively disposed. Therefore, the intermediate member can be made compact.

[0112] In the strap holding mechanism of the present disclosure, the holding member may include a holding member main body portion and a protruding portion that protrudes from the holding member main body portion in the direction of movement, the protruding portion may include an engagement recess portion that is open laterally and of which a dimension in the direction of movement is larger than a dimension of the attachment member in the direction of movement, and the holding member may be movably attached to the intermediate member with the engagement recess portion engaged with the attachment member.

[0113] Accordingly, the holding member can relatively move in the direction of movement with respect to the intermediate member with the attachment member moving in the direction of movement in the engagement recess portion with respect to the holding member. Therefore, a structure that supports the holding member to be movable at the intermediate member can be simplified.

[0114] In the strap holding mechanism of the present disclosure, the intermediate member may include an elastic member that is disposed in the accommodation recess portion and that urges the holding member to the fixation position.

[0115] Accordingly, since the elastic member urges the holding member to the fixation position, the first pin can be made less likely to unintentionally fall off the introduction groove of the intermediate member and the strap can be made less likely to be detached from the intermediate member.

[0116] In the strap holding mechanism of the present disclosure, the holding member may include an abutment surface that abuts against the first pin inserted into the introduction groove through an opening of the introduction groove, and the abutment surface may be inclined with respect to a direction of insertion of the first pin such that the holding member moves toward the attachment and detachment position when the first pin is inserted into the introduction groove in a state where the first pin abuts against the abutment surface.

[0117] Accordingly, since the abutment surface of the holding member is inclined with respect to the direction of insertion of the first pin, it is possible to engage the first pin with the holding member by inserting the first pin into the introduction groove without operating the holding member. Therefore, the strap can be easily attached.

[0037] The strap holding devices 10 are devices provided to couple the straps 120 to the case 111 of the watch main body 110. In the present embodiment, the strap holding device 10 includes the holding member 20 and the intermediate member 30.Holding Member

[0038] The holding member 20 is configured to hold the strap 120 by being engaged with the first pin 123 of the strap 120. In the present embodiment, the holding member 20 includes a holding member main body portion 21 and protruding portions 22.

[0039] The holding member main body portion 21 is accommodated in an accommodation recess portion 313 of the intermediate member 30 which will be described later, and is partially exposed on a rear surface side of the watch 100. The protruding portions 22 are provided to protrude from the holding member main body portion 21. Specifically, the protruding portions 22 are provided to protrude in a direction from the rear surface side of the watch 100 to a front surface side of the watch 100, with respect to the holding member main body portion 21. In other words, the protruding portions 22 are provided to protrude in the direction of movement of the holding member 20 which will be described later, with respect to the holding member main body portion 21. The protruding portions 22 are accommodated in accommodation hole portions 316 formed at a bottom surface of the accommodation recess portion 313, which will be described later.

[0040] In addition, the protruding portions 22 are engaged with an attachment member 34 of the intermediate member 30 which will be described later so that the holding member 20 is attached to the intermediate member 30 to be movable in the accommodation recess portion 313. Specifically, the protruding portions 22 include engagement recess portions 221 that are open laterally, and the engagement recess portions 221 are engaged with the attachment member 34 so that the holding member 20 is supported such that the holding member 20 does not fall off the intermediate member 30.Intermediate Member

[0041] The intermediate member 30 supports the holding member 20 and is fixed to the case 111. In the present embodiment, the intermediate member 30 includes an intermediate member main body portion 31, a second pin 32, elastic members 33, and the attachment member 34.

[0042] An introduction groove 311, an insertion hole 312, and the accommodation recess portion 313 are formed at the intermediate member main body portion 31.

[0043] The introduction groove 311 is a groove into which the first pin 123 of the strap 120 described above is inserted. In the present embodiment, the introduction groove 311 is formed to be open on the rear surface side of the watch 100 at the intermediate member main body portion 31. In addition, an opening portion 314 and a bottom portion 315 are formed at the introduction groove 311.

[0044] As described above, the opening portion 314 is open on the rear surface side of the watch 100 at the intermediate member main body portion 31. The opening portion 314 is an example of an opening of the introduction groove 311 of the present disclosure. The bottom portion 315 is provided at an end portion on an inner side of the introduction groove 311.

[0045] The insertion hole 312 is a hole portion into which the second pin 32 is inserted. In the present embodiment, the insertion hole 312 is formed at the intermediate member main body portion 31 to penetrate in a width direction of the intermediate member main body portion 31. In other words, the insertion hole 312 is formed at the intermediate member main body portion 31 such that the insertion hole 312 penetrates in a direction parallel to the first pin 123, that is, a direction orthogonal to a direction from the front surface side of the watch 100 to the rear surface side of the watch 100, in a state where the strap 120 is attached to the case 111.

[0046] As with the introduction groove 311, the accommodation recess portion 313 is formed to be open on the rear surface side of the watch 100 at the intermediate member main body portion 31. In addition, as described above, the holding member main body portion 21 is accommodated in the accommodation recess portion 313, and the protruding portions 22 are accommodated in the accommodation hole portions 316 formed at the bottom surface of the accommodation recess portion 313.

[0047] The second pin 32 is configured as a so-called spring bar. In addition, the second pin 32 is inserted into the insertion hole 312 of the intermediate member main body portion 31 and is supported by the pair of holding piece portions 112A and 112B of the bow 112. Accordingly, the intermediate member 30 is detachably fixed to the case 111.

[0048] The elastic members 33 are configured as so-called coil springs. In addition, the elastic members 33 are accommodated in the accommodation recess portion 313 together with the holding member 20. More specifically, the elastic members 33 are accommodated to be interposed between the holding member main body portion 21 and the bottom surface of the accommodation recess portion 313. Accordingly, the elastic members 33 are configured to urge the holding member main body portion 21 in the direction from the front surface side of the watch 100 to the rear surface side of the watch 100.

[0049] The attachment member 34 is a member for attachment of the holding member 20 to the intermediate member 30.

[0050] In the present embodiment, the attachment member 34 has a tubular shape and is inserted into the insertion hole 312 of the intermediate member 30. The second pin 32 is inserted into the attachment member 34.

[0051] Accordingly, in the present embodiment, since the second pin 32 for attachment of the intermediate member 30 to the case 111 is inserted into the attachment member 34 having the tubular shape, it is not necessary to provide spaces in the intermediate member 30 in which the second pin 32 and the attachment member 34 are respectively disposed. Therefore, the intermediate member 30 can be made compact.Fixation Position and Attachment and Detachment Position of Holding Member

[0052] Next, a fixation position and an attachment and detachment position of the holding member 20 will be described.

[0053] FIG. 6 is a cross-sectional view showing the fixation position of the holding member 20 and FIG. 7 is a cross-sectional view showing the attachment and detachment position of the holding member 20.

[0054] First, as shown in FIG. 6, in a normal state, the holding member main body portion 21 is urged by the elastic members 33 to move in the accommodation recess portion 313 in a first direction L1 toward the rear surface side of the watch 100, the first direction L1 being shown in FIG. 6. In this state, the opening portion 314 of the introduction groove 311 is partially covered by the holding member main body portion 21 as seen in a cross-sectional view. In the present disclosure, the position of the holding member 20 as shown in FIG. 6 will be referred to as the fixation position.

[0055] In addition, when the holding member main body portion 21 in this state is pressed toward the front surface side of the watch 100, as shown in FIG. 7, the holding member main body portion 21 moves in the accommodation recess portion 313 in a second direction L2 toward the front surface side of the watch 100, the second direction L2 being shown in FIG. 7. In this state, the opening portion 314 of the introduction groove 311 is not covered by the holding member main body portion 21 as seen in a cross-sectional view and is open on the rear surface side of the watch 100. In the present disclosure, the position of the holding member 20 as shown in FIG. 7 will be referred to as the attachment and detachment position.

[0056] As described above, in the present embodiment, the holding member main body portion 21 of the holding member 20 is configured to be movable between the fixation position and the attachment and detachment position by moving in the accommodation recess portion 313 in the first direction L1 and the second direction L2.

[0057] Here, as described above, the holding member 20 moves between the fixation position and the attachment and detachment position. In other words, the holding member 20 moves in the accommodation recess portion 313 in the first direction L1 and the second direction L2, that is, toward the front surface side of the watch 100 and the rear surface side of the watch 100.

[0058] In addition, the attachment member 34 is inserted into the insertion hole 312 that penetrates in the direction orthogonal to the direction from the front surface side of the watch 100 to the rear surface side of the watch 100 as described above. That is, the attachment member 34 is disposed in the insertion hole 312 of the intermediate member 30 in a direction intersecting the direction of movement of the holding member 20 between the fixation position and the attachment and detachment position. More specifically, the attachment member 34 is disposed in a direction orthogonal to the direction of movement of the holding member 20 between the fixation position and the attachment and detachment position. In addition, the attachment member 34 is engaged with the engagement recess portions 221 formed at the protruding portions 22 of the holding member 20. Note that the present disclosure is not limited to the above-described configuration and the attachment member 34 may be disposed along a direction inclined with respect to the direction of movement of the holding member 20 between the fixation position and the attachment and detachment position by approximately 80 degrees as long as the attachment member 34 is configured such that the attachment member 34 intersects the direction of movement of the holding member 20 between the fixation position and the attachment and detachment position so that the attachment member 34 can restrain the holding member 20 from falling off the intermediate member 30.

[0059] In this case, the engagement recess portions 221 are formed such that a dimension H of the engagement recess portions 221 in the direction of movement between the fixation position and the attachment and detachment position is larger than a dimension D of the attachment member 34 in the direction of movement, that is, the diameter of the attachment member 34 having the tubular shape. In addition, the engagement recess portions 221 are engaged with the attachment member 34 so that the holding member 20 is attached to the intermediate member 30 to be movable in the direction of movement between the fixation position and the attachment and detachment position. In other words, the holding member 20 is supported to be movable in the accommodation recess portion 313 with respect to the intermediate member 30.

[0060] Accordingly, the holding member 20 can relatively move in the direction of movement with respect to the intermediate member 30 with the attachment member 34 relatively moving in the direction of movement in the engagement recess portions 221 with respect to the holding member 20. Therefore, a structure that supports the holding member 20 to be movable at the intermediate member 30 can be simplified.

[0061] In addition, in the present embodiment, the holding member 20 is not attached to the intermediate member 30 by means of a screw or the like. Therefore, the intermediate member 30 does not need to be provided with a screw hole. Therefore, even when the intermediate member 30 is formed of a material in which it is difficult to form a screw hole like ceramic, a structure that supports the holding member 20 to be movable at the intermediate member 30 can be easily realized.Attachment and Detachment Method for Strap

[0062] Next, an attachment and detachment method for the strap 120 of the present embodiment will be described.

[0063] FIGS. 8 and 9 are cross-sectional views showing a state where the strap 120 is attached to the case 111.

[0064] First, as shown in FIG. 8, in a state where the first pin 123 of the strap 120 is not inserted into the introduction groove 311, that is, in a state where the strap 120 is not attached to the watch main body 110, the holding member main body portion 21 is pressed in the second direction L2 so that the holding member 20 is moved to the attachment and detachment position. Then, the first pin 123 is inserted toward the bottom portion 315 through the opening portion 314, along the introduction groove 311.

[0065] Then, in a state where the first pin 123 is inserted until the first pin 123 abuts against the bottom portion 315 of the introduction groove 311 thereafter as shown in FIG. 9, the holding member main body portion 21 stops being pressed and then the holding member 20 is urged by the elastic members 33. In this case, the holding member 20 moves in the first direction L1 to move to the fixation position as shown in FIG. 4. In addition, the opening portion 314 of the introduction groove 311 is covered by the holding member main body portion 21 as described above and the first pin 123 is engaged with the holding member main body portion 21. Accordingly, the first pin 123 does not fall off the introduction groove 311 in a state of being engaged with the holding member main body portion 21, so that the strap 120 is attached to the watch main body 110.

[0066] That is, in the present embodiment, since the elastic members 33 urge the holding member 20 to the fixation position, the first pin 123 can be made less likely to unintentionally fall off the introduction groove 311 of the intermediate member 30 and the strap can be made less likely to be detached from the intermediate member 30.

[0067] Meanwhile, when the strap 120 is to be removed from the watch main body 110, the wearer presses the holding member main body portion 21 in a state as shown in FIG. 4 to move the holding member 20 in the second direction L2. Accordingly, the holding member main body portion 21 moves to the attachment and detachment position as shown in FIG. 9, so that the first pin 123 can be moved along the introduction groove 311 and pulled out from the opening portion 314.

[0068] As described above, in the present embodiment, the holding member 20 that holds the strap 120 is supported by the intermediate member 30 attached to the case 111. Therefore, an end portion of the strap 120 only needs to be provided with the first pin 123 extending in the width direction. That is, since a member that couples the strap 120 and the watch main body 110 is attached to the case 111, the size of a member disposed at the end portion of the strap 120 can be reduced and the number of components can also be reduced.

[0069] Note that in the present embodiment, since an abutment surface 211 of the holding member main body portion 21 is inclined with respect to the direction of insertion of the first pin 123, that is, a direction in which the introduction groove 311 is open, it is possible to attach the strap 120 to the watch main body 110 by inserting the first pin 123 into the introduction groove 311 without pressing the holding member main body portion 21.

[0070] That is, when the first pin 123 is inserted into the introduction groove 311 in a state where the holding member main body portion 21 is at the fixation position as shown in FIG. 10, the first pin 123 abuts against the abutment surface 211 of the holding member main body portion 21. Here, in the present embodiment, the abutment surface 211 is inclined with respect to the direction of insertion of the first pin 123 so that the holding member main body portion 21 moves in the second direction L2. Therefore, when the first pin 123 is inserted toward the bottom portion 315 of the introduction groove 311 in such a state, the abutment surface 211 is pressed by the first pin 123 and thus the holding member main body portion 21 moves in the second direction L2 as shown in FIG. 11. Accordingly, the holding member 20 moves to the attachment and detachment position. Therefore, the wearer can attach the strap 120 to the watch main body 110 without pressing the holding member main body portion 21.Action and Effect of First Embodiment

[0071] According to the first embodiment, the following effects can be achieved.

[0072] In the present embodiment, since the holding member 20 that holds the strap 120 by being engaged with the first pin 123 is supported by the intermediate member 30 attached to the case 111, an end portion of the strap 120 only needs to be provided with the first pin 123 extending in the width direction. Therefore, the size of a member disposed at the end portion of the strap 120 can be reduced and the number of components can also be reduced.

[0073] In the present embodiment, since the second pin 32 for attachment of the intermediate member 30 to the case 111 is inserted into the attachment member 34 having the tubular shape, it is not necessary to provide spaces in the intermediate member 30 in which the second pin 32 and the attachment member 34 are respectively disposed. Therefore, the intermediate member 30 can be detachably fixed to the case 111 and the intermediate member 30 can be made compact.

[0074] In the present embodiment, the engagement recess portions 221 are formed such that the dimension H of the engagement recess portions 221 in the direction of movement between the fixation position and the attachment and detachment position is larger than the dimension D of the attachment member 34 in the direction of movement. In addition, the engagement recess portions 221 are engaged with the attachment member 34 so that the holding member 20 is attached to the intermediate member 30 to be movable in the direction of movement between the fixation position and the attachment and detachment position.

[0075] Accordingly, the holding member 20 can relatively move in the direction of movement with respect to the intermediate member 30 with the attachment member 34 relatively moving in the direction of movement in the engagement recess portions 221 with respect to the holding member 20. Therefore, a structure that supports the holding member 20 to be movable at the intermediate member 30 can be simplified.

[0076] In the present embodiment, the intermediate member 30 includes the elastic members 33 that are disposed in the accommodation recess portion 313 and that urge the holding member 20 to the fixation position. Accordingly, since the elastic members 33 urge the holding member 20 to the fixation position, the first pin 123 can be made less likely to unintentionally fall off the introduction groove 311 of the intermediate member 30 and the strap can be made less likely to be detached from the intermediate member 30.

[0077] In the present embodiment, the abutment surface 211 of the holding member 20 is inclined with respect to the direction of insertion of the first pin 123. Therefore, it is possible to engage the first pin 123 with the holding member 20 by inserting the first pin 123 into the introduction groove without operating the holding member 20. Therefore, the strap 120 can be easily attached.

[0078] In the present embodiment, the holding member 20 is not attached to the intermediate member 30 by means of a screw or the like. Therefore, the intermediate member 30 does not need to be provided with a screw hole. Therefore, even when the intermediate member 30 is formed of a material in which it is difficult to form a screw hole like ceramic, a structure that supports the holding member 20 to be movable at the intermediate member 30 can be easily realized.Second Embodiment

In addition, an opening portion 314A and a bottom portion 315A are formed at the introduction groove 311A.

[0091] The insertion holes 312A are hole portions into which the attachment members 34A are inserted. In the present embodiment, the insertion holes 312A are formed at the intermediate member main body portion 31A to be open on the case 111A side at the intermediate member main body portion 31A. In other words, the insertion holes 312A are formed at the intermediate member main body portion 31A to be parallel to a direction along a line linking the 6 o'clock position of the watch 100A to the 12 o'clock position of the watch 100A in a state where the strap 120 is attached to the case 111A.

[0092] As with the first embodiment described above, the accommodation recess portion 313A is formed to be open on the rear surface side of the watch 100A at the intermediate member main body portion 31A. In addition, the holding member main body portion 21A is accommodated in the accommodation recess portion 313A, and the protruding portions 22A are accommodated in accommodation hole portions 316A formed at a bottom surface of the accommodation recess portion 313A.

[0093] The through-holes 317A are hole portions into which the fastening members 35A are inserted and are formed at the intermediate member main body portion 31A to penetrate in a direction from a front surface side of the watch 100A to a rear surface side of the watch 100A.

[0094] The elastic members 33A are accommodated in the accommodation recess portion 313A together with the holding member 20A, as with the first embodiment described above. In addition, the elastic members 33A are configured to urge the holding member main body portion 21A in the direction from the front surface side of the watch 100A to the rear surface side of the watch 100A.

[0095] As with the first embodiment described above, the attachment members 34A are members for attachment of the holding member 20A to the intermediate member 30A. In the present embodiment, the attachment members 34A have columnar shapes and are inserted into the insertion holes 312A of the intermediate member 30A.

[0096] In the present embodiment, the attachment members 34A are inserted into the insertion holes 312A which are formed to be parallel to the direction along the line linking the 6 o'clock position of the watch 100A to the 12 o'clock position of the watch 100A as described above. That is, the attachment members 34A are disposed in the insertion holes 312A of the intermediate member 30A in a direction intersecting the direction of movement of the holding member 20A between the fixation position and the attachment and detachment position.

[0107] In the above-described embodiments, the watches 100, 100A, and 100B are examples of wrist devices. However, the present disclosure is not limited thereto. For example, the present disclosure can be applied to a wrist device such as a pulse rate meter and a strap attached to the wrist device. Furthermore, the watches 100, 100A, and 100B as the wrist devices can be any watch mounted on an arm of a wearer by means of a strap, regardless of whether the watch is a so-called digital watch, an analog watch, or the like.Summary of Present Disclosure

[0108] According to an aspect of the present disclosure, there is provided a strap holding mechanism including: a strap that includes a first pin extending in a width direction, the first pin being provided at an end portion of the strap on a side on which the strap is engaged with a case; a holding member that holds the strap by being engaged with the first pin; and an intermediate member that supports the holding member and that is attached to the case or is provided to be integrated with the case, in which the intermediate member includes an introduction groove into which the first pin is insertable, an accommodation recess portion that accommodates the holding member, and an attachment member that attaches the holding member to the accommodation recess portion to be movable between a fixation position at which the holding member fixes the first pin to the introduction groove and an attachment and detachment position at which the holding member enables removal of the first pin inserted into the introduction groove, the first pin is engaged with the holding member when the first pin is inserted into the introduction groove, and the attachment member is disposed with respect to the intermediate member in a direction intersecting a direction of movement of the holding member between the fixation position and the attachment and detachment position.

[0109] Accordingly, since the holding member that holds the strap by being engaged with the first pin is supported by the intermediate member that is attached to the case or is provided to be integrated with the case, the end portion of the strap only needs to be provided with the first pin extending in the width direction. Therefore, the size of a member disposed at the end portion of the strap can be reduced and the number of components can also be reduced.

[0110] The strap holding mechanism of the present disclosure may further include a second pin that attaches the intermediate member and the case, an insertion hole into which the second pin is inserted may be formed at the intermediate member, the attachment member may be a tubular member inserted into the insertion hole, and the second pin may be inserted into the attachment member.

[0111] Accordingly, since the second pin for attachment of the intermediate member to the case is inserted into the attachment member having the tubular shape, it is not necessary to provide spaces in the intermediate member in which the second pin and the attachment member are respectively disposed. Therefore, the intermediate member can be made compact.

[0112] In the strap holding mechanism of the present disclosure, the holding member may include a holding member main body portion and a protruding portion that protrudes from the holding member main body portion in the direction of movement, the protruding portion may include an engagement recess portion that is open laterally and of which a dimension in the direction of movement is larger than a dimension of the attachment member in the direction of movement, and the holding member may be movably attached to the intermediate member with the engagement recess portion engaged with the attachment member.

[0113] Accordingly, the holding member can relatively move in the direction of movement with respect to the intermediate member with the attachment member moving in the direction of movement in the engagement recess portion with respect to the holding member. Therefore, a structure that supports the holding member to be movable at the intermediate member can be simplified.

[0114] In the strap holding mechanism of the present disclosure, the intermediate member may include an elastic member that is disposed in the accommodation recess portion and that urges the holding member to the fixation position.

[0115] Accordingly, since the elastic member urges the holding member to the fixation position, the first pin can be made less likely to unintentionally fall off the introduction groove of the intermediate member and the strap can be made less likely to be detached from the intermediate member.

[0116] In the strap holding mechanism of the present disclosure, the holding member may include an abutment surface that abuts against the first pin inserted into the introduction groove through an opening of the introduction groove, and the abutment surface may be inclined with respect to a direction of insertion of the first pin such that the holding member moves toward the attachment and detachment position when the first pin is inserted into the introduction groove in a state where the first pin abuts against the abutment surface.

[0117] Accordingly, since the abutment surface of the holding member is inclined with respect to the direction of insertion of the first pin, it is possible to engage the first pin with the holding member by inserting the first pin into the introduction groove without operating the holding member. Therefore, the strap can be easily attached.

[0118] According to another aspect of the present disclosure, there is provided a wrist device including: a case; a strap that includes a first pin extending in a width direction, the first pin being provided at an end portion of the strap on a side on which the strap is engaged with the case; a holding member that holds the strap by being engaged with the first pin; and an intermediate member that supports the holding member and that is attached to the case or is provided to be integrated with the case, in which the intermediate member includes an introduction groove into which the first pin is insertable, an accommodation recess portion that accommodates the holding member, and an attachment member that attaches the holding member to the accommodation recess portion to be movable between a fixation position at which the holding member fixes the first pin to the introduction groove and an attachment and detachment position at which the holding member enables removal of the first pin inserted into the introduction groove, the first pin is engaged with the holding member when the first pin is inserted into the introduction groove, and the attachment member is disposed with respect to the intermediate member in a direction intersecting a direction of movement of the holding member between the fixation position and the attachment and detachment position.
