Description

  The present invention relates to a wristwatch, and more particularly to a wristwatch provided with a solar cell.

Conventionally, in a wristwatch equipped with a solar cell, a transparent substrate is disposed under the watch glass, a ring-shaped solar cell is provided on the lower surface of the transparent substrate, and the upper surface of the transparent substrate corresponding to the solar cell, or a watch There is a structure in which the upper surface of the glass or the lower surface of the watch glass is formed on an uneven surface, and external light is irregularly reflected by the uneven surface to soften the color tone of the solar cell.
Japanese Utility Model Publication No. 60-54991

  However, in such a conventional wristwatch, the color tone of the solar cell can be softened by the uneven surface formed on the upper surface of the transparent substrate corresponding to the solar cell, the upper surface of the watch glass, or the lower surface of the watch glass. However, there is a disadvantage that the ring-shaped solar cell only looks planar through the watch glass and the transparent substrate, and lacks in design and decoration.

  In order to eliminate such inconvenience, a dial plate is arranged on the lower side of the watch glass instead of the transparent substrate, and a ring-shaped solar cell is provided on the dial plate. A ring-shaped transparent parting member having an upper surface formed on an inclined surface is arranged, and the parting member constitutes a solar cell so that it can be seen three-dimensionally. However, in a wristwatch having such a structure, a parting member must be provided between the watch glass and the solar cell, which increases the number of parts and complicates the structure.

  The problem to be solved by the present invention is to provide a wristwatch that can express a solar cell in three dimensions with a simple structure without using another member such as a parting member.

  The invention described in claim 1 includes a timepiece glass and a ring-shaped solar cell disposed on the lower side of the timepiece glass, and the lower surface of the timepiece glass corresponding to the ring-shaped solar cell is provided with the timepiece. The wristwatch is characterized in that an inclined surface that is inclined obliquely downward from the outer peripheral side of the glass toward the inner side is formed.

  According to the first aspect of the present invention, the lower surface of the watch glass corresponding to the ring-shaped solar cell disposed on the lower side of the watch glass is inclined downward as it goes from the outer peripheral side to the inner side of the watch glass. Since the slanted slope is formed, the slanted surface can express the solar cell in three dimensions, so that it is possible to obtain a preferable one in terms of design and decoration, and a parting member as in the conventional example Therefore, it is not necessary to use other parts such as the number of parts, the number of parts is small, the structure is simple, and a low price can be obtained.

(Embodiment 1)
Hereinafter, a first embodiment of a wristwatch to which the present invention is applied will be described with reference to FIG.
FIG. 1 is an enlarged cross-sectional view showing the main part of the wristwatch of the present invention.
This wristwatch includes a wristwatch case 1. A watch glass 2 is attached to the upper part of the watch case 1, and a watch module 3 is incorporated in the watch case 1. A back cover 4 is attached to the lower surface of the watch case 1.

  In this case, the clock module 3 has at least an analog function among an analog function and a digital function. That is, the timepiece module 3 includes a housing 5, a dial plate 6 is disposed on the upper surface of the housing 5, and a circuit board 7 is disposed on the lower surface of the housing 5.

  An analog movement 8 is provided inside the housing 5. In this analog movement 8, the pointer shaft 9 protrudes upward through the through-hole 6a of the dial plate 6, and a pointer 10 such as an hour hand, a minute hand, and a second hand is attached to an upper end portion of the protruding pointer shaft 9, and the pointer 10 is By moving the hand over the plate 6, the time is indicated.

  By the way, on the upper surface of the dial 6, the time characters 11 are arranged at predetermined intervals along the outer periphery of the dial 6, and a ring-shaped solar cell 12 is provided on the outer periphery of the time character 11. Is provided. On the lower surface 2 b of the watch glass 2 corresponding to the ring-shaped solar cell 12, a flat slope 13 is formed that is inclined obliquely downward as it goes from the outer peripheral side to the inner side of the watch glass 2.

  In this case, the watch glass 2 is formed in an inclined curved surface in which the outer peripheral portion of the upper surface 2a is gently inclined upward, and the central portion of the upper surface 2a is formed in a substantially flat surface. Further, the lower surface 2b of the watch glass 2 is formed into an inclined curved surface that is gently inclined upward from the lower end of the inclined surface 13 except for the inclined surface 13 on the outer peripheral side, and the central portion thereof is substantially parallel to the upper surface 2a. This is formed on a flat surface, thereby forming a concave shape except for the inclined surface 13.

  According to such a wristwatch, the pointer 10 and the hourglass 11 of the dial 6 can be seen from the outside of the wristwatch case 1 through the watch glass 2 so that the time can be known and provided on the dial 6. The ring-shaped solar cell 12 can be irradiated with external light through the watch glass 2, and the ring-shaped solar cell 12 can be seen from the outside of the watch case 1 through the watch glass 2.

  At this time, a flat inclined surface 13 is formed on the lower surface 2b of the watch glass 2 corresponding to the ring-shaped solar cell 12 so as to incline downward as it goes from the outer peripheral side to the inner side of the watch glass 2. Therefore, the solar cell 12 can be three-dimensionally expressed by the inclined surface 13, thereby obtaining a preferable one in terms of design and decoration.

  In this case, in particular, the lower surface 2b of the watch glass 2 is formed in a concave shape excluding the inclined surface 13, so that a portion corresponding to the inclined surface 13 and a portion corresponding to the other concave portion are externally provided. Therefore, the solar cell 12 can be emphasized more than the dial 6 and expressed in a three-dimensional manner, thereby obtaining a more favorable design and decoration. it can.

  Further, since the solar cell 12 can be three-dimensionally represented by the slope 13 formed on the lower surface 2b of the watch glass 2 corresponding to the ring-shaped solar cell 12, another part such as a parting member as in the conventional example can be provided. There is no need to use it. For this reason, the number of parts is small, the structure is simple, and a low price can be obtained.

  In the first embodiment, the case where the lower surface 2b of the watch glass 2 is formed in a concave shape except for the inclined surface 13 is not limited to this. For example, as illustrated in FIG. Except for this, the lower surface 2b of the watch glass 2 may be formed as a flat surface. In this case, the upper surface 2a of the watch glass 2 is also formed on a flat surface parallel to the lower surface 2b.

  Even in such a structure, as in the first embodiment, the portion corresponding to the inclined surface 13 and the portion corresponding to the other flat surface are different in appearance from the outside, and in particular, the dial 6 is expressed almost planarly. Therefore, the solar cell 12 can be emphasized more than the dial 6 and expressed three-dimensionally, and this also makes it possible to obtain a more favorable design and decoration.

(Embodiment 2)
Next, a second embodiment of a wristwatch to which the present invention is applied will be described with reference to FIG. The same parts as those of the first embodiment shown in FIG.
This watch has a structure in which the watch module 20 incorporated in the watch case 1 has a digital function, and the structure other than this is substantially the same as that of the first embodiment.

  That is, the timepiece module 20 includes an upper housing 21 and a lower housing 22. A transparent plate 23 is disposed on the upper surface of the upper housing 21, and a ring-shaped solar cell 12 is provided on the outer peripheral portion of the upper surface of the transparent plate 23. The upper housing 21 is provided with a liquid crystal display device 24 for electro-optically displaying information such as time, and the circuit board 7 is disposed between the upper housing 21 and the lower housing 22. Has been.

  In this case, the liquid crystal display device 24 is supported by being pressed against the flange portion 21a of the upper housing 21 by an interconnector 25 having one end portion (the left end portion in FIG. 3) disposed on the circuit board 7. In addition, the circuit board 7 is electrically connected. Further, the lower surface 2b of the watch glass 2 corresponding to the ring-shaped solar cell 12 provided on the transparent plate 23 is slanted from the outer peripheral side to the inner side of the watch glass 2 as in the first embodiment. A flat slope 13 that is inclined downward is formed.

  In addition, the upper surface 2a of the watch glass 2 is also formed in an inclined curved surface whose outer peripheral portion is gently inclined upward as in the first embodiment, and the central portion on the upper surface is formed in a flat surface. Yes. Further, the lower surface 2b of the watch glass 2 is also formed as an inclined curved surface that gently slopes upward from the lower end portion of the inclined surface 13 except for the inclined surface 13 on the outer peripheral side, and its central portion is substantially parallel to the upper surface 2a. This is formed on a flat surface, thereby forming a concave shape except for the inclined surface 13.

  According to such a wrist watch, information displayed on the liquid crystal display device 24 through the watch glass 2 and the transparent plate 23 can be viewed from the outside of the watch case 1, so that the time can be known, and the transparent plate 23 can be known. The ring-shaped solar cell 12 provided above can be irradiated with external light through the watch glass 2, and the ring-shaped solar cell 12 can be seen from the outside of the watch case 1 through the watch glass 2.

  Also at this time, as in the first embodiment, the lower surface 2b of the watch glass 2 corresponding to the ring-shaped solar cell 12 is planarly inclined obliquely downward as it goes from the outer peripheral side to the inner side of the watch glass 2. Therefore, the solar cell 12 can be three-dimensionally expressed by the inclined surface 13, whereby a preferable one in terms of design and decoration can be obtained.

  Also in this case, since the lower surface 2b of the watch glass 2 is formed in a concave shape except for the inclined surface 13, the portion corresponding to the inclined surface 13 and the portion corresponding to the other concave portion are separated from the outside. The appearance is different, so that the solar cell 12 can be emphasized and expressed in three dimensions rather than the dial 6, and thereby, a more favorable design and decoration can be obtained.

  In addition, since the solar cell 12 can be three-dimensionally represented by the inclined surface 13 formed on the lower surface 2b of the watch glass 2 corresponding to the ring-shaped solar cell 12, as in the first embodiment, the parting like the conventional example is performed. There is no need to use separate parts such as members. For this reason, the number of parts is small, the structure is simple, and a low price can be obtained.

  In the second embodiment, the case where the lower surface 2b of the watch glass 2 is formed in a concave shape except for the inclined surface 13 is not limited to this. For example, a modification of the first embodiment shown in FIG. Similarly to the example, the lower surface 2b of the watch glass 2 may be formed on a flat surface except for the inclined surface 13. Also in this case, the upper surface 2a of the watch glass 2 is formed on a flat surface parallel to the lower surface 2b.

  Even in such a structure, as in the second embodiment, the portion corresponding to the inclined surface 13 and the portion corresponding to the other flat surface are different in appearance from the outside, and in particular, the dial 6 is expressed almost planarly. Therefore, the solar cell 12 can be emphasized more than the dial 6 and expressed three-dimensionally, and this also makes it possible to obtain a more favorable design and decoration.

  Moreover, although the said Embodiment 1, 2 and each modification example described the case where the slope 13 formed in the lower surface 2b of the timepiece glass 2 was formed in planar shape, it is not restricted to this, For example, FIG. As shown in FIG. 4A, it may be formed into a convex curved surface that gently curves, or as shown in FIG. 4B, it may be formed into a concave curved surface that gently curves. Even if the inclined surface 13 is curved as described above, the solar cell 12 can be represented in a three-dimensional manner as in the first and second embodiments.

It is the expanded sectional view which showed the principal part of the wristwatch to which this invention is applied. (Embodiment 1) It is the expanded sectional view of the principal part which showed the modification of the timepiece glass of FIG.
