Description

[0001] This application is a divisional application of the following invention patent application: Application date: March 26, 2020; Application number: 202010222888.9; Invention title: Clock and watch letter plate and clock. Technical Field

[0002] Embodiments of the present invention relate to a clock faceplate and a clock. Background Technology

[0003] A decorative component and a clock having the decorative component are disclosed (see Patent Document 1). In this decorative component, a base layer made of white material is formed on the surface of a metal letter plate, a light-emitting layer containing a light-emitting material (light-emitting phosphor) is formed on the surface of the base layer, and a cover layer made of transparent acrylic resin is formed on the surface of the light-emitting layer.

[0004] Prior art literature Patent documents Patent document 1: Japanese Patent Application Publication No. 11-281765. Summary of the Invention

[0005] The problem that the invention aims to solve However, in watches, translucent materials are sometimes used for the outer surface of the lettering panel. When this outer surface is constructed as a single layer, and a phosphorescent coating is applied to the surface or back of the outer surface as in the prior art example described above, the texture and tone of the phosphorescent coating before emitting light are displayed as is, making it possible to easily identify its phosphorescent function in bright light. However, considering that the original texture of the outer surface is compromised by the application of the phosphorescent coating, the tone in bright light is limited. Furthermore, considering that the emission color of the phosphorescent coating varies due to the influence of the display panel, the emission color of the phosphorescent coating is also limited. Therefore, a concern is that if the phosphorescent coating is applied to the surface or back of the outer surface of a translucent layer, it lacks decorative appeal or visibility.

[0006] The embodiments of the present invention take into account the above facts and aim to make it easy to display the color tone of the exterior part of the text board with light-glow function in a bright place, and to make it difficult to detect the presence of light-glow function.

[0007] Solution for solving the problem The clock faceplate according to the first method includes: a base component; an outer surface portion disposed on the aforementioned base component, which is composed of multiple layers and has light transmittance; and a light-glowing material disposed on the back side of the aforementioned outer surface portion on the side of the aforementioned base component.

[0008] In this clock faceplate, because the outer part is composed of multiple layers, the light-colored hue of the luminescent material on the back of the outer part is difficult to show on the outer side. Therefore, in bright light, the original color of the outer part is easily visible, and the presence of the luminescent function may be difficult to discern.

[0009] Regarding the second method, in the clock face plate involved in the first method, the thickness of the aforementioned exterior part varies depending on its position.

[0010] In this clock faceplate, because the thickness of the outer surface varies depending on its position, the light transmittance of the outer surface also varies depending on its position. Therefore, it is possible to achieve a display where the brightness or hue of the light-emitting material in a dimly lit environment varies depending on its position.

[0011] Regarding the third approach, in the watch lettering plate involved in the first or second approach, a first decorative addition part with light transmission is provided on the surface of the aforementioned exterior part.

[0012] In this watch lettering panel, the decorative quality of the exterior portion can be enhanced by a first decorative addition portion that is translucent, while simultaneously allowing light-emitting material to pass through the first decorative addition portion and emit light. Therefore, the expandability of the decorative addition can be improved.

[0013] Regarding the fourth method, in the clock face plate involved in the third method, the light transmittance of the aforementioned first decorative addition varies depending on its position.

[0014] Regarding the fifth method, in the watch lettering plate involved in any of the first to fourth methods, at least one of the aforementioned back and side surfaces of the aforementioned exterior part is provided with a second decorative addition part that has light-blocking properties.

[0015] In this clock faceplate, the presence of the luminescent material and the second decorative element is difficult to discern in bright light. Simultaneously, when the luminescent material emits light in dim light, the second decorative element, which has light-blocking properties, restricts the luminescent area of ​​the material, resulting in a visual appearance different from that in bright light. Therefore, the decorative quality of the exterior surface can be further enhanced.

[0016] The sixth method involves a clock face plate comprising: a base component; an outer surface portion disposed on the aforementioned base component, which is composed of multiple layers and has light transmittance; and a light-glowing material disposed between the aforementioned base component and the aforementioned outer surface portion.

[0017] In this watch face plate, because the outer part is composed of multiple layers, the light-colored hue of the luminescent material disposed between the base component and the outer part is difficult to show on the surface of the outer part. Therefore, in bright light, the original hue of the outer part can be easily displayed, and the presence of the luminescent function may be difficult to discern. Furthermore, the luminescent material may or may not be attached to the outer part. Additionally, the luminescent material may or may not be attached to the base component.

[0018] The clocks involved in the seventh method have the clock face plates that are present in any one of the first to sixth methods.

[0019] In this clock, the value of the product can be increased by enhancing the visibility or decorative appeal of the clock faceplate.

[0020] The effects of the invention According to an embodiment of the present invention, in a bright location, the hue of the exterior portion of a letterplate with a light-glow function can be easily displayed, and the presence of the light-glow function may be difficult to detect.

[0032] Hereinafter, a method for carrying out the present invention will be described based on the accompanying drawings.

[0033] [First Implementation Method] exist Figure 1 In this embodiment, the clock face plate 10 has a base component 12, an outer surface part 14, and a light-emitting material 16.

[0034] The base component 12 is formed, for example, in a plate shape, and can be various shapes such as circular, oval, quadrilateral, or tonneau-shaped, consistent with the shape of the clock face plate 10. For the material of the base component 12, for example, metal or resin is used. (Illustrations omitted; the base component 12 is disposed on the clock 100.) Figure 10 On the movement of the watch.

[0035] The outer appearance section 14 is located on a portion or the entire area of ​​the base component 12, and is composed of multiple layers, exhibiting light transmission. Materials used for the layers include seashells, marble, and ceramics. The thickness of the outer appearance section 14 is constant, for example, approximately 0.1 mm. This thickness can be appropriately varied to adjust the light transmission or color tone of the outer appearance section 14.

[0036] The phosphorescent material 16 is disposed on the back surface 14B of the base member 12 side of the appearance part 14. The phosphorescent material 16 is formed by, for example, applying a phosphorescent coating to the back surface 14B of the appearance part 14. The phosphorescent material 16 is a phosphorescent phosphor, for example, a compound represented by MAl2O4, in which a compound composed of strontium (Sr), magnesium (Mg) and barium (Ba) representing the metal element M is formed into a parent crystal, and europium (Eu) is contained as an activator, and dysprosium (Dy) is contained as a co-activator.

[0037] (effect) In this embodiment, since the outer surface 14 is composed of multiple layers, unlike the case where the outer surface is composed of a single transparent layer, light is not allowed to pass through unobstructed. Therefore, the light-glowing material 16 provided on the back surface 14B of the outer surface 14 is difficult to show on the surface 14A of the outer surface 14. As a result, in bright environments, the original color of the outer surface 14 is easily visible, and the presence of the light-glowing function may be difficult to discern.

[0038] [Second Implementation] exist Figure 2 In the clock faceplate 20 according to this embodiment, in the first embodiment, the thickness of the outer surface portion 14 varies depending on its position. In the illustrated example, the thickness of the outer surface portion 14 increases linearly from left to right. However, the thickness is not limited to this; it can also increase linearly. Alternatively, it can be constructed such that, for example, grooves are provided on the outer surface portion 14 using engraving or the like, thereby periodically increasing or decreasing the thickness of the outer surface portion 14.

[0039] (effect) In this embodiment, since the thickness of the outer surface portion 14 varies depending on its position, the light transmittance of the outer surface portion 14 also varies depending on its position. Therefore, when the light-emitting material 16 emits light in a dimly lit place, it is possible to achieve the effect that the brightness or hue of the light emitted by the outer surface portion 14 varies depending on its position.

[0040] For the other parts, since they are the same as in the first embodiment, the same symbols are used for the same parts in the drawings, and the descriptions are omitted.

[0041] [Third Implementation Method] exist Figure 3 In the watch lettering plate 30 according to this embodiment, a first decorative addition portion 21 with light transmittance is provided on the surface 14A of the outer appearance portion 14. The first decorative addition portion 21 is formed by means of printing, coating decoration, vapor deposition, etc., on the surface 14A of the outer appearance portion 14. The first decorative addition portion 21 may also be formed by grooves or the like, which are provided on the surface 14A of the outer appearance portion 14 by engraving. In this embodiment, the first decorative addition portion 21 is formed with uniform thickness and uniform density.

[0042] (effect) In this embodiment, the decorative properties of the exterior portion 14 can be enhanced by the light-transmitting first decorative addition portion 21, while simultaneously allowing the light-emitting material 16 to emit light through the first decorative addition portion 21. When the light from the light-emitting material 16 passes through both the exterior portion 14 and the first decorative addition portion 21, the light emission at the surface 14A of the exterior portion 14 differs from the case where only the light passes through the exterior portion 14. Therefore, the expandability of the decorative addition can be improved.

[0043] For the other parts, since they are the same as in the first embodiment, the same symbols are used for the same parts in the drawings, and the descriptions are omitted.

[0044] [Fourth Implementation Method] exist Figure 4 In the clock faceplate 40 according to this embodiment, in the third embodiment, the light transmittance of the first decorative addition portion 21 varies depending on its position. In the illustrated example, the thickness of the first decorative addition portion 21 in the right half is twice that in the left half. Alternatively, the density of the first decorative addition portion 21 can vary depending on its position to change its light transmittance.

[0045] (effect) In this embodiment, since the light transmittance of the first decorative addition portion 21 varies depending on its position, the brightness or hue of the light-emitting material 16 emitting light in a dimly lit place can vary depending on its position. Furthermore, this allows for the creation of gradients or patterns.

[0046] For other parts, since they are the same as in the first or third embodiment, the same symbols are used for the same parts in the drawings, and the description is omitted.

[0047] [Fifth Implementation Method] exist Figure 5 In the watch lettering plate 50 according to this embodiment, in the first embodiment, a second decorative addition portion 22 with light-shielding properties is provided on the back surface 14B of the outer surface portion 14. The second decorative addition portion 22 is formed by means such as printing, coating decoration, or vapor deposition on the outer surface portion 14. In this embodiment, the second decorative addition portion 22 is partially provided near the center of the back surface 14B of the outer surface portion 14. A luminescent material 16 is provided on the back surface 14B of the outer surface portion 14, including the back side of the second decorative addition portion 22. That is, the luminescent material 16 is provided overlapping the second decorative addition portion 22. In addition, the second decorative addition portion 22 may also be provided on the surface side 14A of the outer surface portion 14, or it may be provided on both the surface side 14A and the back surface 14B of the outer surface portion 14.

[0048] (effect) In this embodiment, similar to the first embodiment, it is difficult to discern the presence of the luminescent material 16 and the second decorative additive 22 in bright locations. Simultaneously, when the luminescent material 16 emits light in dim locations, the light-emitting area of ​​the luminescent material 16 can be limited by the light-shielding second decorative additive 22, resulting in a visual appearance different from that in bright locations. Figure 5 In the example shown, since the second decorative addition portion 22 is partially located near the center of the back surface 14B of the exterior portion 14, the light from the luminescent material 16 is partially blocked by the second decorative addition portion 22. Therefore, when the luminescent material 16 emits light in a dimly lit environment, the central area on the surface 14A of the exterior portion 14 where the second decorative addition portion 22 is located appears darker. Thus, according to this embodiment, the decorative quality of the exterior portion 14 in dimly lit environments can be further improved.

[0049] For the other parts, since they are the same as in the first embodiment, the same symbols are used for the same parts in the drawings, and the descriptions are omitted.

[0050] [Sixth Implementation Method] exist Figure 6 In the clock faceplate 60 according to this embodiment, in the fifth embodiment, the second decorative addition part 22 is provided in the right side region of the back surface 14B of the appearance part 14.

[0051] (effect) In this embodiment, since the second decorative addition portion 22 is disposed biased towards the right side of the rear surface 14B of the outer surface portion 14, the light from the luminescent material 16 is partially blocked by the second decorative addition portion 22. Therefore, when the luminescent material 16 emits light in a dimly lit environment, the right side region of the outer surface 14A where the second decorative addition portion 22 is located appears darker. Thus, according to this embodiment, the decorative properties of the outer surface portion 14 can be further improved.

[0052] For other parts, since they are the same as in the first or fifth embodiment, the same symbols are used for the same parts in the drawings, and the description is omitted.

[0053] [Seventh Implementation Method] exist Figure 7 In the watch letter plate 70 according to this embodiment, an outer appearance portion 14 is provided on a base member 12 with holes 18 formed therein. A luminescent material 16 is provided in the holes 18 of the base member 12 on the back surface 14B of the outer appearance portion 14. In the illustrated example, the thickness of the base member 12 and the thickness of the luminescent material 16 are the same, but the thickness of the luminescent material 16 may also be thinner than that of the base member 12.

[0054] (effect) In this embodiment, similar to the first embodiment, since the outer appearance part 14 is composed of multiple layers, the hue of the outer appearance part of the text panel with light-glow function can be easily displayed in bright places, and the presence of the light-glow function may be difficult to discern. In addition, in dim places, since only the portion of the light-glow material 16 present emits light, different displays can be achieved in bright and dim places.

[0055] [Example] exist Figure 8 In the clock 100 using the clock face plate 10 according to the first embodiment, the visual appearance of the clock face plate 10 in a dimly lit environment is shown. This clock 100 includes, for example, an hour hand 24, a minute hand 26, a second hand 28, two short hands 32, and a power reserve indicator hand 34 indicating the winding state of the mainspring. The outer part 14 is arranged in an arc along the power reserve indicator scale 35 in the clock face plate 10. Figure 1 As shown, a light-glowing material 16 is provided on the back surface 14B of the exterior portion 14. However, since the exterior portion 14 is composed of a laminate, the light-colored hue of the light-glowing material 16 is difficult to be visible on the surface 14A of the exterior portion 14. Figure 1 It is evident that in bright environments, the presence of the light-gathering function is difficult to discern. Therefore, in bright environments, the hue of the exterior part 14 becomes more readily apparent. On the other hand, in dim environments, the exterior part 14 appears to glow overall, thus enabling a different appearance compared to bright environments.

[0056] exist Figure 9 In the clock 100 using the clock face plate 20 according to the second embodiment, the visual appearance of the clock face plate 20 in a dimly lit environment is shown. Regarding the arrangement of the hour hand 24, etc., [the text continues with details about the clock face plate 20 and its placement]. Figure 8 The example shown is similar. In this example, the thickness of the arc-shaped appearance portion 14 increases as it rotates counterclockwise. As a result, in dimly lit places, the appearance portion 14 appears to emit light in a gradient manner. On the other hand, in bright places, the appearance portion 14 appears the same.

[0057] exist Figure 10 In the clock 100 to which the clock face plate 40 according to the fourth embodiment is applied, the visual appearance of the clock face plate 40 in a dimly lit environment is shown. Figure 10 The image shows not only the dial 40 for clockwork but also the housing 36 and the wristband 37. Only an hour hand 24 and a minute hand 26 are shown as hands. Figure 10In the clock face, the outer part 14 is shown between the central axis of the hour hand 24 and the six o'clock position, but this outer part 14 is provided on the entire surface of the clock face plate 40. The first decorative addition part 21 is, for example, a geometric pattern, specifically, a combination of lines that are hexagonal in shape when viewed from above and straight lines that extend radially from the center of the hexagon. Such a first decorative addition part 21 is formed by grooves or the like, for example, provided on the surface of the outer part 14 by engraving.

[0058] In this example, the first decorative addition 21 or the phosphorescent material 16 ( Figure 4 The hue of ) is not on the surface 14A of the exterior part 14. Figure 4 It is evident that in bright light, the presence of the light-glowing function and the first decorative addition 21 is difficult to discern. On the other hand, in dim light, the first decorative addition 21 appears to float due to the light emission of the light-glowing material 16. Both the first decorative addition 21 and the outer surface 14 are translucent, but because the first decorative addition 21 overlaps with the outer surface 14, the visual appearance changes between the parts where the first decorative addition 21 is present and the parts where the first decorative addition 21 is absent. Therefore, the decorative effect can be improved.

[0059] exist Figure 11 In (A), the visual appearance of the clock face plates 50 and 60 in a dimly lit environment is shown in a clock 100 using the fifth or sixth embodiment. The clock face plates 50 and 60 are provided as hands: an hour hand 24, a minute hand 26, and a second hand 28. In this example, the outer part 14 is provided at each of the 1 o'clock to 3 o'clock and 5 o'clock to 12 o'clock positions. At the 4 o'clock position, for example, a date display window 42 is provided.

[0060] In this example, a second decorative addition 22 with light-shielding properties is disposed overlapping the outer appearance portion 14 to add a border to each outer appearance portion 14. For example... Figure 11 As shown in (B), in a bright location, the second decorative addition 22 or the light-emitting material 16 ( Figure 5 , Figure 6 The light-colored hue is not on the surface 14A of the exterior part 14. Figure 5 , Figure 6 It is evident that in bright light, the presence of the second decorative addition 22 and the light-gathering function is difficult to discern. On the other hand, in dim light, such as... Figure 11 As shown in (A) and (C), the appearance part 14 appears to glow due to the light emission of the photoluminescent material 16, but the light is blocked because the second decorative addition part 22 has light-blocking properties. As a result, the appearance part 14 appears to have a black border. Since the border, which is not visible in bright places, appears to float in dim places, the decorative effect of the appearance part 14 is further enhanced.

[0061] In this way, by improving the visibility or decorative appeal of the dial on the clock, the commercial value of the clock 100 can be increased.

[0062] [Other Implementation Methods] The above describes an example of an embodiment of the present invention. However, the embodiments of the present invention are not limited to the above description. Various modifications can be made without departing from the spirit of the present invention.

[0063] The above embodiments can be used in appropriate combinations. For example, by combining the second and fourth embodiments, the brightness or hue of the light emitted by the appearance portion 14 in dimly lit places can be displayed more broadly.
