An embodiment of a wearable device according to the present invention will be described with reference to FIGS. 1 to 6. FIG.
Although various technically desirable limitations are attached to the embodiments described below for carrying out the present invention, the scope of the present invention is not limited to the following embodiments and illustrated examples.

[First embodiment]
First, a first embodiment of the present invention will be described.
1 and 2 are a front view and an exploded perspective view of a timepiece 100 according to the first embodiment. 3(a) is a perspective view of the watch main body 3 included in the watch 100 as viewed from the other main surface side, and FIG. 3(b) is a cross-sectional view of the watch 100 taken along line AA in FIG. .
In the following description, up, down, left, and right directions of the timepiece 100 refer to the directions shown in FIG. That is, the "vertical direction" refers to the 12 o'clock to 6 o'clock direction, and the "horizontal direction" refers to the 3 o'clock to 9 o'clock direction.

As shown in FIGS. 1 and 2, a watch 100 according to the first embodiment is an example of a wearable device according to the present invention, and is a wrist watch worn on a user's wrist. Specifically, the timepiece 100 includes an exterior case 2 and a timepiece main body 3 .
The exterior case 2 is formed in a substantially rectangular box shape that is slightly elongated in the vertical direction. The exterior case 2 has a recess 21 that opens to the front side (viewing side). The concave portion 21 is open on both left and right sides, and has guide grooves 22 on both upper and lower inner surfaces. Each guide groove 22 is for guiding movement of the watch body 3 and extends in the left-right direction.
Watchbands 24 are attached to both upper and lower ends of the exterior case 2 .

The watch main body 3 is formed in a substantially rectangular plate shape corresponding to the recess 21 of the exterior case 2, and fits into the recess 21 in a normal state. The watch main body 3 is an example of an operating part according to the present invention, and is supported by the exterior case 2 so as to be rotatable about an axis extending in the vertical direction.
Specifically, the watch main body 3 has rotating shafts 31 coaxially protruding vertically at the left and right end portions of the upper and lower end surfaces thereof. The rotating shaft 31 is slidably fitted in the guide groove 22 of the exterior case 2 . Therefore, the timepiece main body 3 can move in the left-right direction and can rotate around the rotation shaft 31 as the rotation shaft 31 is guided by the guide groove 22 .
Further, locking portions (not shown) are provided on both upper and lower end surfaces of the watch main body portion 3 . By engaging the engaging portion with the inner side surface of the concave portion 21 of the outer case 2, the main surface of the watch body 3 faces forward, as will be described later. is held in the exterior case 2 .

A clock module 33 formed in a rectangular plate shape is provided on one main surface side (the front side in the normal state) of the clock main body 3 .
A time display section 34 for displaying the time is provided on the frontmost side of the clock module 33 . The time display unit 34 includes a dial 34a and a plurality of hands 34b that rotate around the center on the dial 34a to display the time.
Inside the clock module 33 are housed a battery as a power source, a circuit board on which a control circuit is mounted, a hand movement mechanism for moving a plurality of hands 34b, and the like.

As shown in FIGS. 3(a) and 3(b), a heat-resistant portion 36 is provided on the other main surface side of the watch body 3 (the back side in the normal state) over almost the entire main surface. .
The heat-resistant portion 36 is a portion to which a thin sheet of heat-resistant resin is attached. However, the heat-resistant portion 36 is not particularly limited as long as it improves the heat resistance of the base material of the watch main body 3. For example, the heat-resistant portion 36 may be coated with a silicon-based heat-resistant coating. Also, the range of the heat-resistant portion 36 is not particularly limited, but it is preferably the widest possible range of the other main surface of the watch main body 3 . For example, the heat-resistant portion 36 may be provided to avoid the time display portion 34 on one main surface side on which the clock module 33 is provided. Moreover, the heat-resistant portion 36 may be provided so as to cover the entire exterior case 2 as long as the time display portion 34 is avoided.

4A and 4B are diagrams for explaining the operation of the watch body 3. FIG.
In the timepiece 100, as shown in FIG. 4A, in the normal state, the timepiece main body 3 is held (locked) by the exterior case 2 with one main surface exposed. In this state, the time display portion 34 of the timepiece module 33 of the timepiece body portion 3 is exposed on the front side of the timepiece 100, and the heat resistant portion 36 on the opposite side is hidden.

From this state, as shown in FIG. 4B, the watch main body 3 is slid to the left and right sides to move the rotating shaft 31 to the end of the guide groove 22, and then the watch main body 3 is turned over. .
Then, as shown in FIG. 4(c), when the watch main body 3 is turned upside down and fitted into the concave portion 21 of the outer case 2, the watch main body 3 is held (locked) by the outer case 2 in this state. ) is done. In this inverted state, the heat-resistant portion 36 of the timepiece main body 3 is exposed on the front side of the timepiece 100, and the timepiece module 33 on the opposite side is hidden. As a result, the heat resistance of the watch main body 3 can be improved.

However, the timepiece main body 3 may change the exposed state of the heat-resistant portion 36 according to its operation. Here, the “exposed state” of the heat-resistant portion 36 includes the exposed area of the heat-resistant portion 36 (the area exposed to the outside). Therefore, for example, a heat-resistant portion 36 is provided to avoid the time display portion 34 on one main surface side on which the timepiece module 33 is provided, and the heat-resistant portion 36 including this portion is provided as the timepiece main body portion 3 operates. The entire exposed area may vary.

As described above, according to the first embodiment, the timepiece main body 3 having the heat-resistant portion 36 and operably supported changes the exposed state of the heat-resistant portion 36 as it moves.
As a result, the heat resistance of the timepiece 100 can be favorably improved.

Further, according to the first embodiment, the watch main body 3 is configured so that it can take a state in which the heat-resistant portion 36 is hidden and a state in which the heat-resistant portion 36 is exposed in accordance with its operation.
As a result, the user can improve the heat resistance of the timepiece 100 (timepiece body 3) by operating the timepiece body 3 to expose the heat-resistant portion 36 as necessary. Therefore, the heat resistance of the timepiece 100 can be favorably improved without, for example, forming a heat-resistant resin on the time display portion 34 to deteriorate its visibility.

Further, according to the first embodiment, the watch main body 3 has the time display portion 34 on one main surface and the heat-resistant portion 36 on the other main surface. It is rotatably supported so that one side is exposed and the other side is hidden.
As a result, the time display part 34 is exposed in the normal state, and the heat-resistant part 36 is exposed by rotating the watch main body 3 when heat resistance is to be increased, thereby suitably heat-resistant without impairing the appearance in the normal state. can improve sexuality.

The specific configuration of the watch main body 3 is not particularly limited as long as it is configured to change the exposed state of the heat-resistant portion 36 in accordance with its operation.
For example, the watch body 3 may have a shape other than a rectangle (for example, a circle) when viewed from the front. The watch main body 3 may have a structure in which it slides in the vertical direction and rotates about an axis in the horizontal direction, or may have a structure in which it rotates without sliding. Alternatively, the watch main body 3 may be detachable from the outer case 2, and may be attached to the outer case 2 with one of its main surfaces exposed to the front.

[Second embodiment]
Next, a second embodiment of the invention will be described.
FIG. 5 is a front view of a timepiece 200 according to the second embodiment.
In the following description, the up, down, left, and right directions of the watch 200 refer to the directions shown in FIG. That is, the "vertical direction" refers to the 12 o'clock to 6 o'clock direction, and the "horizontal direction" refers to the 3 o'clock to 9 o'clock direction.

As shown in FIG. 5, a watch 200 according to the first embodiment is an example of a wearable device according to the present invention, and includes an exterior case 4, a rotating bezel 5, and a plurality of shutter members 6 (see FIG. 6). I have.
The exterior case 4 supports other parts. Watchbands 41 are attached to both upper and lower ends of the exterior case 4 .

The rotating bezel 5 has an annular plate shape when viewed from the front, and is arranged on the front side of the exterior case 4 . Specifically, the rotating bezel 5 is supported by the outer case 4 so as to be rotatable around a central axis along the thickness direction of the timepiece 200 (perpendicular to the paper surface of FIG. 5).
A time display unit 42 for displaying the time is arranged radially inside the rotating bezel 5 . The time display unit 42 includes a dial 42a and a plurality of hands 42b that rotate around the center on the dial 42a to display the time.

FIG. 6 is a diagram for explaining a plurality of shutter members 6. FIG.
As shown in this figure, the plurality of shutter members 6 are arranged on the rear side of the rotary bezel 5 (back side of the paper surface) and on the front side (front side of the paper surface) of the time display unit 42 . are arranged over the entire circumference of the The plurality of shutter members 6 are an example of the operating portion according to the present invention, and each is supported by the exterior case 4 so as to be rotatable about an axis along the thickness direction of the timepiece 200 .

Specifically, each shutter member 6 is formed in the shape of a plate that tapers toward the inner periphery of the timepiece 100, and has a rotating shaft 61 protruding in the thickness direction of the timepiece 200 on the outer periphery. there is The rotating shaft 61 is rotatably supported by the exterior case 4 .
A heat-resistant portion 62 is provided on the inner peripheral side (tip side) of each shutter member 6 on the front side surface.
The heat-resistant portion 62 is a portion to which a thin sheet of heat-resistant resin is attached. However, the heat-resistant portion 62 is not particularly limited as long as it improves the heat resistance of the base material of each shutter member 6, and may be, for example, a portion coated with a silicon-based heat-resistant coating. Although the range of the heat-resistant portion 62 is not particularly limited, it includes the exposed portion when exposed from the rotating bezel 5 (see FIG. 6(b)) on the front side surface of each shutter member 6. Preferably, the range may cover the entire surface of each shutter member 6 . Moreover, the heat-resistant portion 62 may be provided so as to cover the entire other portions of the timepiece 200 including the exterior case 4 and the rotating bezel 5 as long as the time display portion 42 is avoided.

As the rotating bezel 5 rotates, each shutter member 6 is hidden behind the rotating bezel 5 (the state shown in FIG. 6A ), and the heat-resistant portion 62 extends radially of the rotating bezel 5 . It is connected to the rotating bezel 5 so that it can be exposed to the inside (the state shown in FIG. 6(b)).
Therefore, the plurality of shutter members 6 are hidden behind the rotating bezel 5 in a normal state, exposing the time display section 42 . When the rotating bezel 5 is rotated from this state, a plurality of shutter members 6 are exposed inside from the rotating bezel 5 along with the rotation.
Then, the heat-resistant portion 62 of each shutter member 6 is exposed on the front side of the timepiece 100 , and the time display portion 42 located on the far side is hidden by the shutter member 6 . As a result, the heat resistance of the timepiece 200 (time display unit 42) can be improved.

However, the shutter member 6 may change the exposed state of the heat-resistant portion 62 along with its operation. Here, the “exposed state” of the heat-resistant portion 62 includes the exposed area (the area exposed to the outside) of the heat-resistant portion 62 . Therefore, for example, the heat-resistant portion 62 may be provided to avoid the time display portion 42, and the exposed area of the entire heat-resistant portion 62 including this portion may change as the shutter member 6 operates.

As described above, according to the second embodiment, the same effects as those of the first embodiment can be obtained.
That is, the shutter member 6 that has the heat resistant portion 62 and is operably supported changes the exposed state of the heat resistant portion 62 as it operates.
As a result, the heat resistance of the timepiece 200 can be favorably improved.

Further, according to the second embodiment, the shutter member 6 is configured to be able to take a state in which the heat-resistant portion 62 is hidden and a state in which the heat-resistant portion 62 is exposed along with its operation.
Accordingly, the user can improve the heat resistance of the clock 200 (time display section 42) by operating the shutter member 6 to expose the heat-resistant section 36 as necessary. Therefore, the heat resistance of the timepiece 200 can be favorably improved without, for example, forming a heat-resistant resin on the time display portion 42 to deteriorate its visibility.

According to the second embodiment, each shutter member 6 is hidden behind the rotating bezel 5 as the rotating bezel 5 rotates, and the heat-resistant portion 62 is positioned radially inward of the rotating bezel 5 . It is connected to the rotating bezel 5 so that it can be exposed to the outside.
As a result, the time display part 42 is exposed in the normal state, and the rotating bezel 5 is rotated to expose the heat-resistant part 62 when the heat resistance is desired to be improved, thereby suitably heat-resistant without impairing the appearance in the normal state. can be improved.
