Description

  The present invention relates to a timepiece dial and a timepiece.

  Conventional luminescent dials for watches have used luminescent agents containing a radioactive substance that emits light or phosphorescent luminescent agents that release light energy after storing the irradiated light energy. Recently, it is common to use a luminous luminous agent that does not contain radioactive materials. For example, in Patent Document 1, a large number of recesses formed on the upper surface of a metal lower plate are filled with a luminous luminescent agent, and after applying a clear lacquer on the surface of the luminous luminescent agent, A timepiece dial has been disclosed in which a ground glass upper surface member is fixed to an upper surface with an adhesive.

JP 7-43477 A

  According to the timepiece dial described in Patent Document 1, since the luminous phosphorescent agent is filled in the recesses formed in a lattice shape on the upper surface of the metal lower plate, A pattern partitioned in a lattice shape from the upper surface of the plate can be visually recognized through the upper surface member, and a dial decoration with a different taste can be realized as compared with a case where a phosphorescent luminous agent is applied to the entire old dial.

However, since the lower plate and the upper surface member are close to each other, the luminous agent can be visually recognized through the upper surface member in a bright place, and a good decorative property cannot always be obtained. Further, such a timepiece dial cannot obtain a different appearance between a bright place and a dark place where the lattice pattern cannot be seen in a bright place and the lattice pattern is seen in a dark place.
Moreover, since the upper surface member is formed of ground glass, the ground glass material can be seen as it is when viewed from the upper surface side of the timepiece dial, and the appearance is not suitable for high-priced products.

  The present invention has been made in view of such a problem, and its purpose is to provide a watch character having a high-quality appearance in a bright place and a different appearance from a bright place in a dark place. Is to provide a board.

  In order to solve the above-mentioned problems, a timepiece dial of the present invention includes a lower substrate having a recess formed on the surface, a luminous phosphorescent agent placed inside the recess, and a surface on which the recess of the lower substrate is formed. And a semi-transparent porcelain substrate superimposed on the side.

  Further, in addition to the above device, the luminous luminous agent preferably uses a light emitting substrate in which an aluminate compound is added as a main component and a rare earth element activator is added.

  Moreover, in addition to the said device, it is preferable that the thickness of a luminous luminous agent is formed in the range of 0.1 mm to 0.3 mm.

  Further, in addition to the above idea, it is preferable that a region not overlapping with the concave region of the porcelain substrate is painted with a ceramic paint.

  Further, in addition to the above device, it is preferable that a glaze having a light semi-transmitting property or a light transmitting property is baked on the surface of the porcelain substrate.

  The timepiece of the present invention incorporates the timepiece dial described above.

It is a top view which shows the dial for timepieces concerning 1st Example of this invention. It is sectional drawing cut | disconnected by the AA line of FIG. It is a graph which shows the relationship between the thickness of a luminous luminous agent, and a brightness | luminance. It is a top view which shows the wristwatch carrying the timepiece dial which concerns on 1st Example.

  Hereinafter, a timepiece dial plate 10 according to an embodiment of the present invention will be described with reference to the drawings. In each embodiment described below, the timepiece dial 10 is exemplified by a dial mounted on the wristwatch 1.

(First Example)
FIG. 1 is a plan view showing a timepiece dial plate 10 according to the first embodiment, and FIG. 2 is a cross-sectional view taken along line AA of FIG. As shown in FIGS. 1 and 2, the timepiece dial plate 10 includes a semi-transparent porcelain substrate 11 and a lower substrate 20 that are superposed on each other. A recess 21 is formed on the surface 20 a of the lower substrate 20. The lower substrate 20 and the porcelain substrate 11 are fixed by an adhesive layer 40 interposed therebetween. A luminous phosphorescent agent 30 is applied to the inside of the recess 21, and the recess 21 is filled with the luminous phosphorescent agent 30. A hole 25 that penetrates the lower substrate 11 and the porcelain substrate 20 is formed in the central portion of the timepiece dial plate 10. A guide support shaft (not shown) is inserted into the hole 25.

  A time display scale 6 is provided on the surface 11 a of the porcelain substrate 11. The time display scale 6 is formed by printing using ink, pigment, ceramics paint, or the like. Alternatively, the time display scale 6 itself may be manufactured using a metal piece, and the time display scale 6 may be formed by sticking the time display scale 6 to a predetermined position on the surface 11 a of the porcelain substrate 11.

  The porcelain substrate 11 is a substrate made of porcelain having a bluish milky white translucency that is made into a plate by kneading porcelain clay made of porcelain stone as a raw material, and is fired at a high temperature of about 1300 ° C. As the porcelain, for example, Arita ware or Imari ware is representative, and what is generally called white porcelain is preferable. In this embodiment, the porcelain substrate 11 is polished on both sides so that the thickness becomes 0.3 mm after being fired at high temperature. The porcelain substrate 11 has light translucency at a thickness of around 0.3 mm. If the fired porcelain surface is smooth, the polishing may not be performed, and either the front surface 11a or the back surface 11b may be polished.

  The lower substrate 20 is formed of a metal plate such as brass or white (silver), and two dial legs 13 are erected on the back surface 20b. The dial foot 13 has a function of fixing the timepiece dial 10 to a clock body (not shown). In the present embodiment, the thickness of the lower substrate 20 is set to 0.3 mm to 0.4 mm. The depth of the recess 21 is preferably as deep as the workability and strength of the lower substrate 20 allow. When the thickness of the lower substrate 20 is 0.3 mm, it is set within a range of 0.15 mm ± 0.05 mm. When the thickness of the lower substrate 20 is 0.4 mm, the thickness is set in the range of 0.2 mm ± 0.1 mm. Since the concave portion 21 is filled with the luminous agent 30, the depth of the concave portion 21 corresponds to the thickness of the luminous agent 30.

  Note that when the thickness of the lower substrate 20 is X and the depth of the recess 21 is Y, the depth Y is (X ÷ 2) − (X ÷ 4) ≦ Y ≦ (X ÷ 2) + ( The range of X ÷ 4) is preferable, and the range of (X ÷ 2) − (X ÷ 6) ≦ Y ≦ (X ÷ 2) + (X ÷ 6) is more preferable.

  Moreover, although the depth of the recessed part 21 affects the brightness | luminance of the luminous luminous agent 30 with which it fills, this is later mentioned with reference to FIG.

  The planar shape of the recess 21 formed in the lower substrate 20 is a character such as a brand name, for example. In the first embodiment illustrated in FIG. 1, brand names (not shown for public order and moral violations) are illustrated. In addition to the brand name, the recess 21 may be formed of a product name, a trademark, a raw material production area, a production production area or a trademark of a porcelain substrate, or a design such as a flower or an arbitrary pattern, and is designed in design. Anything can be freely selected.

  The porcelain substrate 11 and the lower substrate 20 are joined by an adhesive layer 40. The adhesive layer 40 is an adhesive, and a UV adhesive (ultraviolet curable adhesive), a thermosetting adhesive or an anaerobic adhesive, or an adhesive can be used. As the adhesive layer 40, a material having high light transmittance is selected, and the thinner it is, the better the bonding strength can be maintained.

  The phosphorescent luminous agent 30 uses a light emitting substrate in which an aluminate compound is a main component and a rare earth element activator is added, and absorbs light (ultraviolet rays) such as sunlight and a fluorescent lamp and is dark. By the way, it emits spontaneous light for a long time. In the present embodiment, the light energy transmitted through the porcelain substrate 11 is absorbed by the phosphorescent luminous agent 30 and emitted in a dark place. Since the porcelain substrate 11 has light translucency, the luminous agent 30 cannot be visually recognized in a bright place. On the other hand, when the ultraviolet light is irradiated by a black light or in a dark place, the light emitted from the luminous luminous agent 30 passes through the porcelain substrate 11 and the brand name formed by the luminous luminous agent 30 can be visually recognized. In addition, there are phosphorescent luminous pigments and zinc sulfide type as luminous phosphorescent agents, but they are not suitable for the timepiece dial 10 because they cannot have high luminance and the afterglow time is short. The phosphorescent luminous agent may be employed.

  The brightness of the luminous agent 30 varies depending on the thickness of the luminous agent 30 applied. This will be described with reference to FIG.

  FIG. 3 is a graph showing the relationship between the thickness of the luminous luminous agent 30 and the luminous luminance factor. The horizontal axis represents the thickness (mm) of the luminous luminous agent 30, and the vertical axis represents the luminous luminance factor (%). The luminous luminance rate represents the ratio of the luminance at each thickness with respect to the standard luminance included in the luminous luminous agent 30. As shown in FIG. 3, the luminous luminance factor approaches 100% near 0.3 mm, and the luminance does not increase even if the luminous luminous agent 30 is made thicker. In addition, a luminous luminance factor of 95% is obtained near a thickness of 0.2 mm, and a luminous luminance factor of 80% is obtained around a thickness of 0.1 mm. In addition, at 0.1 mm or less, it can be seen that as the luminous agent 30 becomes thinner, the luminous luminance rate rapidly decreases and sufficient luminance cannot be obtained.

  In the present embodiment, as described above, when the thickness of the lower substrate 20 is 0.3 mm, the depth of the recess 21 is formed in the range of 0.1 mm to 0.2 mm, and the thickness of the lower substrate 20 is In the case of 0.4 mm, the depth of the recess 21 is formed in the range of 0.10 mm to 0.3 mm. Since the luminous luminous agent 30 is filled in the recess 21, the luminous luminous agent 30 has a thickness of 0.1 mm to 0.3 mm, and a luminous luminance factor of 80% or more can be secured. The thickness of the lower substrate 20 is selected by setting the total thickness determined from the case structure and design of the wristwatch 1.

  Next, the wristwatch 1 incorporating the timepiece dial 10 according to the present embodiment will be described with reference to the drawings.

  4A and 4B are plan views showing the wristwatch 1 equipped with the timepiece dial 10 according to the first embodiment, wherein FIG. 4A shows an appearance visually recognized in a bright place, and FIG. 4B shows an appearance visually recognized in a dark place. Show. In the wristwatch 1 illustrated in FIG. 4, a watch body (not shown) to which a watch dial 10 is attached is stored in a watch case 2. The timepiece dial 10 is provided with a time display scale 6 and includes an hour hand 3 and a minute hand 4 attached to a pointer shaft (not shown). A crown 7 is attached in the 3 o'clock direction of the watch case 1. As shown in FIG. 4A, in the bright place, the luminous watch 30 (characters of (not shown for public order and morals violation)) cannot be seen, and the entire wristwatch 1 can be seen.

  When the wristwatch 1 is irradiated in the dark or with ultraviolet rays, as shown in FIG. 4 (B), the brand name written on the luminous luminous agent 30 (not shown for violation of public order and morals) appears as if it appears. Looks like. 4B shows the entire wristwatch 1 so that the entire wristwatch 1 can be seen. However, in an environment such as darkness, the brand name is written with the luminous luminous agent 30 (no violation of public order and morals. I can't see anything other than the letters listed. Further, when the black light is irradiated, the characters (not shown due to violation of public order and morals) look clear, and the watch case 2, the hour hand 3, the minute hand 4, and the time display scale 6 can be visually recognized.

  In the first embodiment described above, as disclosed in Patent Document 1, a large number of recesses formed on the upper surface of a metal lower plate are filled with a luminous luminous agent, and a clear lacquer is provided on the surface of the luminous luminous agent. It is not the structure which apply | coats and provides the upper surface member made from ground glass on the upper surface of this clear lacquer. In the first embodiment, a phosphorescent nocturnal agent 30 is filled in a concave portion 21 formed on the surface 20a of the lower substrate 20, and a light semi-transparent porcelain substrate 11 is superposed and fixed on the lower substrate 20. It is a structure to do.

  According to such a structure, in a bright place, characters such as letters, trademarks, flowers and arbitrary patterns formed on the lower substrate 20 are not visible, and only the milky white porcelain substrate 11 having a translucency unique to porcelain is visible. . In a dark place, characters, trademarks, flowers, and arbitrary patterns provided on the lower substrate 20 appear to float through the porcelain substrate 11. As described above, the timepiece dial 10 having different appearances in the bright place and the dark place can be provided.

  Moreover, even if it is not dark like darkness, if the porcelain substrate 11 is irradiated with black light, the porcelain substrate 11 has characters, trademarks, flowers and arbitrary patterns formed on the lower substrate 20. It looks like it floats through and gives a surprise to the viewer.

  Further, the porcelain substrate 11 has a texture unique to white porcelain, and Arita ware (Imari ware) and the like are accepted with a high-quality texture of the porcelain itself. When the timepiece dial plate 10 to which such a porcelain substrate 11 is attached is viewed in a bright place, a texture as a so-called luxury (high-priced) wristwatch can be obtained.

(Second embodiment)
Next, a timepiece dial 10 according to a second embodiment of the present invention will be described. The second embodiment is characterized in that a pattern, characters, and the like are attached to the surface 11a of the porcelain substrate 11 with a ceramic paint. Although illustration is omitted, patterns, letters, and the like are attached to the region of the surface 11a of the porcelain substrate 11 that is not overlapped with the concave portion 21 filled with the luminous agent 30 with ceramics paint. There are red, blue, yellow, and green colors for ceramics, which can represent various colors.

  When the porcelain substrate 11 is made of Arita ware (or Imari ware) porcelain (white porcelain), a traditional pattern of Arita ware can be created by painting a traditional design (called dyeing) using a paint called Kuresu. It is possible to realize a timepiece dial plate 10 having an indigo color and decorativeness. Thus, by painting on the surface 11a of the porcelain substrate 11, it is possible to realize a timepiece dial plate 10 having a different appearance from the white porcelain background and various designs.

(Third embodiment)
Next, a timepiece dial 10 according to a third embodiment of the present invention will be described. The third embodiment is characterized in that glaze is baked on the surface 11 a of the porcelain substrate 11. Although illustration is omitted, the surface 11a of the porcelain substrate 11 is fired with glaze. Examples of the glaze include a transparent glaze with high light transmittance and a light semi-transmissive white magnetic glaze.

  Thus, by applying glaze to the porcelain substrate 11, the texture of the porcelain (white porcelain) can be changed. Further, the surface 11a of the porcelain substrate 11 has very fine irregularities, and the surface 11a can be finished to a smooth surface by the glaze. The irregularities on the surface 11a scatter light. When the light emitted from the phosphorescent luminous agent 30 is scattered, characters and other designs can be expressed softly. However, when the surface 11a is smoothed with a glaze, the light scattering on the surface 11a is reduced, and the characters and the like are rendered. Visible clearly. The glaze may be applied to the entire surface of the porcelain substrate 11.

  As in the second embodiment, the surface 11a of the porcelain substrate 11 may be attached with a picture (referred to as a bottom picture) and then fired with a glaze. ). Alternatively, the ceramic substrate 11 may be fired after the glaze is applied without firing.

  In each of the embodiments described above, the phosphorescent nocturnal agent 30 is arranged on the back side of the thin porcelain substrate 11 so that the watch dial 10 having an unprecedented porcelain texture is formed in a bright place and the dark place is provided in a dark place. The watch dial 10 having a different appearance from that of a bright place, such as the design of a brand name, appears to be raised by the light emitted from the luminous agent 30. Can be provided.

  In addition, if the porcelain substrate 11 is formed using a traditional technique such as using a white porcelain substrate, painting a porcelain, or applying glaze to the porcelain, the traditional technology can be used for products other than ceramics. It is possible to contribute to the development and development of traditional industries.

  The timepiece dial plate 10 according to the present invention is illustrated as being mounted on the wristwatch 1, but is not limited to a wristwatch and can be applied to a table clock, a wall clock, and the like.

  In each of the above-described embodiments, the adhesive layer 40 is provided between the porcelain substrate 11 and the lower substrate 20, but may be integrated with another member such as a clip. Alternatively, the lower substrate 20 may not be provided, and a recess may be provided on the back surface 11b of the porcelain substrate 11, and the luminous agent 30 may be placed in the recess.

  Furthermore, the technology of the present invention is applicable not only to the timepiece dial 10 but also to the application of the luminous luminous agent 30 on the back side of the porcelain product, or the drawing of the luminous luminous agent 30 and the like. is there. In this way, a texture peculiar to porcelain can be obtained in a bright place, and a design by the phosphorescent luminous agent 30 can be raised in a dark place, and a porcelain product having a design that is different from conventional ones can be provided.
