Detailed Implementation

[0026] First, refer to Figures 1-4 The structure of the watch 100 according to the first embodiment will be described.

[0027] Furthermore, for ease of explanation, the X-axis, Y-axis, and Z-axis are shown as three mutually perpendicular axes in each figure. The direction parallel to the X-axis is called the "X-axis direction," the direction parallel to the Y-axis is called the "Y-axis direction," and the direction parallel to the Z-axis is called the "Z-axis direction." The Z-axis direction is vertical, and the XY plane is horizontal. The front end of the arrow in each axis direction is called the "positive side," and the base end is called the "negative side." The positive side of the Z-axis direction is called "up" or "above," and the negative side is called "down" or "below." The view from the +Z direction is referred to as a top view or a plane. The surface on the +Z side is described as the upper surface, and the surface on the opposite side (the -Z direction) is described as the lower surface.

[0028] like Figure 1 As shown, the watch 100 includes: a watch body 10, which displays the time, etc.; and a watch strap 20, which has a base 21 supporting the watch body 10 (see reference). Figure 3 , Figure 4 ) and the watch strap body 22 connected to the base 21.

[0029] exist Figure 1 In the watch 100 shown, the watch body 10 is installed in a manner that allows it to be easily attached to and detached from the watch strap 20 (see reference). Figure 5 Therefore, the watch strap 20 can be directly installed by replacing the watch body 10 with other watch bodies. Furthermore, the watch body 10 can be directly installed by replacing the watch strap 20 with other watch straps. Additionally, a description of the specific installation and removal mechanism is omitted.

[0030] The main body 10 of the clock has a cylindrical casing 11 (see reference). Figure 4 An organic core 12 is disposed inside the housing 11 (see reference). Figure 2 The watch face 13 is made of resin or metal, and hands 14, including a second hand, minute hand, and hour hand, are arranged on the upper side of the watch face 13. The watch face 13 also has an opening, which will be described later. The hands 14 are driven by the movement 12.

[0031] The movement 12 includes a stepper motor and a gear train (not shown) that drive the pointer 14, and a control circuit board (not shown) that controls the drive of the stepper motor. The movement 12 has an opening described later. Furthermore, the movement 12 can be a mechanical movement powered by a mainspring or a quartz movement powered by a battery.

[0032] like Figure 4 As shown, the housing 11 is provided with a cover component 15 that covers one opening and a rear cover 16 that covers the other opening. The cover component 15 is made of a transparent material such as glass. Figure 3 and Figure 4As shown, the back cover 16 has: an outer periphery formed of metal, fixed to the housing 11; and a transmissive region 17 disposed on the inner side of the outer periphery, allowing the movement 12 to be viewed from the outside. The transmissive region 17 of the back cover 16 is made of a transparent component such as glass. Alternatively, the entire back cover 16 may be made of glass, not just the transmissive region 17.

[0033] The watch body 10 allows the dial 13, hands 14, and movement 12 to be viewed through the cover member 15. In this embodiment, the entire cover member 15 is a transmissive area, but it can also be made non-transmissive by printing or the like, so that at least a portion is a transmissive area. Furthermore, the surface of the dial 13 or hands 14 that is visible to the eye is referred to as the display surface.

[0034] And, as Figure 4 As shown, the watch strap 20 is mounted on the watch body 10. A base 21 is disposed on the watch strap 20 opposite to the back cover 16 of the watch body 10. The base 21 is connected to the watch strap body 22.

[0035] Next, refer to Figures 5-7 Explain the structure of watch band 20.

[0036] like Figure 5 and Figure 6 As shown above, the watch strap 20 includes a base 21 disposed opposite to the back cover 16 of the watch body 10, and a strap body 22 connected to the base 21. When the base 21 is disposed opposite to the back cover 16, the base 21 and the back cover 16 approximately overlap when viewed from above. Furthermore, when the watch body 10 is mounted on the strap body 22, the upper surface of the base 21, i.e., the back cover side of the base, contacts the back cover 16.

[0037] like Figure 5 As shown, the base 21 is formed with the same shape as the clock body 10. Furthermore, the base 21 is not limited to a circle; it can also be rectangular. Preferably, a circle or a rectangle can be selected to correspond to the shape of the clock body 10. Additionally, from an aesthetic point of view, the external dimensions of the base 21 are preferably smaller than those of the clock body 10.

[0038] Furthermore, a decorative portion 23 is attached to the center of the back cover side of the base 21. Specifically, a recess 21a for arranging the decorative portion 23 is provided in the center of the base 21. The area of ​​the base 21 without the decorative portion 23 is referred to as the first region 21b. The area of ​​the base 21 with the recess 21a containing the decorative portion 23 is referred to as the second region 21c. When the watch body is mounted on the strap 20, the upper surface of the first region 21b on the back cover side contacts the back cover 16, and the recess 21a of the second region 21c is recessed inward relative to the upper surface of the first region 21b towards the side opposite to the back cover 16.

[0039] like Figure 6 As shown, the decorative portion 23 is positioned to overlap with the transmissive area 17 of the back cover 16. The decorative portion 23 only needs to overlap with at least a portion of the transmissive area 17 of the back cover 16. Alternatively, the decorative portion 23 can be configured to correspond to the shape of the transmissive area 17. For example, if the transmissive area 17 is circular, the decorative portion 23 is also circular, so that the entire transmissive area 17 and the entire decorative portion 23 substantially coincide when viewed from above. This prevents excessive attachment of the decorative portion 23 and allows for efficient visual visibility of the decorative portion 23. Furthermore, the extent of the decorative portion 23 can be wider than the transmissive area 17 of the back cover 16 to allow for sufficient alignment. Additionally, the decorative portion 23 can be in contact with or separate from the back cover 16.

[0040] The total thickness of the base 21 is, for example, 0.7 mm. The depth of the recess 21a is, for example, 0.4 mm to 0.5 mm.

[0041] The base 21 may be made of metal materials such as BS (brass), SUS (stainless steel), or titanium alloy. Alternatively, it may be made of resin. Furthermore, the base 21 may be a two-piece structure with a metal outer circumference and a resin inner circumference, and the inner circumference may be designed to be detachable.

[0042] Materials other than metals that can be used as the base 21 include, for example, vinyl chloride, ABS, acrylic, polycarbonate, MC nylon, polyethylene, polyacetal, PET, paper phenol, cloth phenol, EVA, cast nylon, polystyrene, polyurethane, rubber, glass, etc.

[0043] Decorative part 23 may be a light-emitting element, such as a fluorescent coating. Examples of light-emitting elements include luminescent coatings and phosphorescent coatings. Examples of fluorescent coatings include modified vinyl resin coatings and acrylic emulsion coatings. Examples of luminescent coatings include tritium. Examples of phosphorescent coatings include acrylic resins, vinyl resins, polyurethane resins, and acrylic emulsion resins.

[0044] The main body 22 of the watch strap is made of, for example, a rigid resin material, and is bent to wrap around the arm. Alternatively, the main body 22 of the watch strap can also be made of metal.

[0045] like Figure 4As shown, in the area where the opening 18a of the dial 13 overlaps with the opening 18b of the movement 12, the decorative part 23 of the base 21 can be viewed through the cover member 15. The area where the openings 18a and 18b overlap is called the viewing area 18. The opening 18b in the movement 12 is formed by reducing the weight of the base plate and bridges constituting the movement 12. Furthermore, the openings 18a and 18b can overlap perpendicularly to the back cover 16 or overlap obliquely relative to the back cover 16. That is, the phrase "able to view the decorative part 23 of the base 21 through the transmission area of ​​the cover member 15" means that in addition to being able to directly view the decorative part 23, it also includes being able to indirectly view it; the viewing area 18 only needs to be formed such that the decorative part 23 of the base 21 can be viewed directly or indirectly.

[0046] By using such a watch 100, the decorative effect can be enhanced even if the base 21 completely covers the back of the watch body 10. For example, in the dark, light emitted from the decorative part 23 of the base 21 leaks out from the gaps in the internal structure of the watch, i.e., the viewing area 18, so that it can be seen directly or indirectly, thus diffusing light.

[0047] As described above, the watch 100 of the first embodiment has a watch body 10 and a watch strap 20. The watch body 10 has a cylindrical case 11; a movement 12 disposed inside the case 11; a cover member 15 covering one opening of the case 11 and having a transmissive area; and a back cover 16 covering the other opening of the case 11 and having a transmissive area 17. The watch strap 20 is mounted on the watch body 10 and has a base 21 opposite to the back cover 16 of the watch body 10 and a watch strap body 22 connected to the base 21. The base 21 has a decorative part 23 at a position overlapping with the transmissive area 17 of the back cover 16, and the decorative part 23 can be seen through the transmissive area of ​​the cover member 15.

[0048] According to this structure, the movement 12 can be viewed from the side of the cover member 15. A decorative part 23 is attached to the base 21, so the decorative part 23 of the base 21 can be observed from the side of the cover member 15, which can enhance the decorativeness of the watch 100.

[0049] Furthermore, in the watch 100 of the first embodiment, the decorative part 23 preferably has a light-emitting element as a light-emitting part. According to this structure, since it has a light-emitting part, the light-emitting part can be viewed from the cover member 15 side, which can improve the decorativeness of the watch 100.

[0050] Furthermore, in the watch 100 of the first embodiment, the base 21 preferably has: a first region 21b having a surface that contacts the back cover 16; and a second region 21c that is recessed relative to the surface of the first region 21b toward the side opposite to the back cover 16, wherein a decorative portion 23 is provided in the second region 21c. According to this structure, since the decorative portion 23 is provided in the recess 21a that forms the second region, the fit between the decorative portion 23 and the back cover 16 can be improved, thereby improving visibility from the cover member 15 side.

[0051] Furthermore, in the watch 100 of the first embodiment, it is preferable that the decorative part 23 is configured to correspond in shape to the transmissive area 17. With this structure, it is possible to suppress the addition of unnecessary decorative parts 23 to the base 21, and the decorative part 23 can be viewed efficiently.

[0052] Furthermore, the watch strap 20 of the first embodiment has a base 21 opposite to the back cover 16 of the watch body 10 and a watch strap body 22 connected to the base 21. The base 21 has a decorative part 23 on the side opposite to the back cover 16.

[0053] According to this structure, when the watch strap 20 is installed on the watch body 10, the decorative part 23 of the base 21 can be viewed from the side of the cover member 15, thus improving the decorative appearance of the watch strap 20 and the watch 100.

[0054] Next, refer to Figures 7-13 The watch 101 and watch strap 120 of the second embodiment will be described.

[0055] like Figures 7-13 As shown, in the watch 101 of the second embodiment, the decorative portion 123 of the base 21 constituting the watch strap 120, which is a mesh-like part, differs from that of the watch 100 of the first embodiment. Other structures are largely the same. Therefore, in the second embodiment, the parts that differ from those in the first embodiment will be described in detail, while other repetitive parts will be appropriately omitted.

[0056] like Figure 8 As shown, in the second embodiment, the watch 101 can be seen in the viewing area 18 of the watch body 10, where the decorative part 123, which is a patterned mesh-like light-emitting part, is visible.

[0057] like Figure 9 As shown, the components of the movement 12 can be viewed from the back of the watch 101 through the mesh-like decorative part 123 provided on the base 21 and the transmission area 17 of the back cover 16.

[0058] like Figure 10 As shown, the mesh-like decorative part 123 can be seen in the viewing area 18 where the opening 18a of the dial 13 overlaps with the opening 18b of the movement 12.

[0059] like Figure 11 As shown, the base 21 of the watch strap 120 has a recess 21a in the center. Figure 9 As shown, a decorative part 123, which appears mesh-like when viewed from above, is attached to the recess 21a. Figure 10 , Figure 12 and Figure 13 As shown, the decorative part 123 has a light-emitting element 123a disposed in the recess 21a and a plurality of through holes 123b formed by a plurality of openings in a patterned manner. The light-emitting element 123a has the same structure as the light-emitting element in the first embodiment described above.

[0060] In this way, by making the decorative part 123 of the base 21 mesh-like, a variety of designs can be created to suit the user's preferences. In addition, the internal structure of the watch body 10 can be seen in outline from the back of the base 21, which enhances the decorative effect.

[0061] As described above, in the watch 101 of the second embodiment, the decorative part 23 preferably has an opening. According to this structure, since it has multiple through holes 123b forming a patterned opening, the pattern can be viewed from the cover member 15 side through the gap in the movement 12, the pattern can be seen from the base 21 side, and the movement 12 can be viewed through the through holes 123b. Therefore, the decorative quality of the watch 101 can be improved.

[0062] Hereinafter, variations of the above-described embodiments will be described.

[0063] As mentioned above, the decorative part 23 is not limited to being viewed from the visual area 18 of the clock body 10; it can also be viewed from... Figure 14 A base 21 is mounted on the main body 10 of the clock shown. Figure 14 This is a top view showing the structure of a modified example of watch 102.

[0064] like Figure 14 As shown, in the modified watch 102, the movement 112 is made of a transparent component, allowing the decorative portion 23 of the base 21 to be seen throughout the entire area except for the dial 13. Furthermore, the hands 14, which serve to indicate the time, are preferably not transparent. However, they may also be made of a transparent component. Additionally, the dial 13 may also be made of a transparent component. This increases the visible area 18 of the decorative portion 23 of the base 21, further enhancing its decorative appeal.

[0065] Furthermore, the decorative parts 23 and 123 have light-emitting elements, but are not limited to light-emitting elements; they may also be composed of metal foil, shell, bright lines (lamellae), holograms, lacquer, etc. In addition, to prevent surface deterioration, the decorative parts 23 and 123 in the above embodiment are preferably formed with a protective film on their surface.

[0066] Furthermore, the decorative part 123 of the second embodiment is not limited to a mesh shape; as a patterned opening, it can also be radial, grid-like, striped, geometrically shaped, etc. Alternatively, it can be displayed through dotted openings, such as in dot painting. While the decorative part 123 of the second embodiment has a light-emitting element, the base can also have patterned openings, allowing the base itself to function as a decorative part; therefore, it may not have a light-emitting element.

[0067] Additionally, regarding displaying dotted drawings through dotted openings, such as... Figure 15 As shown in the watch strap 220, images of insects such as butterflies can also be depicted in the recess 21a of the base 21. In this case, the decorative part 123 may or may not have a light-emitting element, which can enhance the decorative effect.

[0068] Furthermore, the base 21 is not limited to having a recess 21a formed in the center. For example, an opening area may exist on the wearing side of the base 21 near the watch 100, extending from the center to the outer periphery of the base 21. This allows sweat to be easily removed when wearing the watch 100. Additionally, the base 21 is preferably made of metal, as its rigidity and durability are higher than those made of resin. Furthermore, the base 21 is not limited to a shape where the thickness of the center is thinner than the thickness of the outer periphery; for example, it may be constructed by bending a flat plate to create a recess relative to the outer periphery.
