3 References Cited Claims, 3 Drawing igures UNITED STATES PATENTS 3,505,804 4/1970 Hofstein 58/23 R 1- POLYCI'IROMATIC WATCH DIAL PLATE The present invention relates to a decorative watch and, more particularly to a polychromatic dial plate of a watch.
I-Ieretofore, a luminous paint coating has been applied on the pointers and the figures of a watch so that even in the dark the user can read a correct time. However, such a coating is used for that purpose only and has no decorative or magic effects. Also, there have been many decorative dial plates with beautiful and colorful designs and some of them are polychromic but none of them become polychromatic according to temperature variations. In other words, they only become polychromic due to the visual angle of the viewer, or to the effect of light and shade, or the like. On the contrary, the dial plate according to the present invention employs a liquid crystal film coating on the dial plate, either on the plate surface or on the firgure portion, and the liquid crystal film having characteristic of exhibiting a variety of colors according to the change of the ambient temperature or of the body heat of the user, gives rise to an excellent decorative and magic effect to the viewer, in addition to the normal function of the watch.
Therefore, an object of the present invention is to provide a decorative and magic watch having a-polychromatic dial plate which exhibits a variety of colors according to the change of the ambient temperature.
Another object of the present invention is to provide a decorative and magic watch having a polychromatic dial plate wherein the surface of the dial plate excluding the figure portion is coated with a liquid crystal film so that the dial plate may have a variety of colors according to the change of the ambient temperature.
Still another object of the present invention is to provide a decorative and magic watch having a polychromatic dial plate wherein the figure portion excluding the surface of the dial plate is coated with a liquid crystal film so that the figure portion may have a variety of colors in contrast to the surface of the dial plate according to the change of the ambient temperature.
The present invention will now be explained in detail by way of example, with reference to the accompanying drawings in which:
FIG. 1 shows a plain view of a watch dial plate according to the present invention;
FIG. 2 shows a vertical sectional view taken from A-A line of FIG. l in which a liquid crystal film is coated on the surface of the dial plate excluding the figure portion; and
FIG. 3 shows a vertical sectional view taken from A-A' line of FIG. I in which a liquid crystal film is coated only on the figure portion.
Referring to FIG. 1 and FIG. 2, a polychromatic watch dial plate according to the present invention roughly consists ofa dial plate I, a figure portion generally denoted by numeral 2, pointers 3, a watch frame 4 and a front glass 5.
Referring to FIG. 2, the surface of the dial plate 11, with the exception of the figure portion 2, is coated with a liquid crystal film 6. The figure portion 2 is made of, or drawn with, a material different, in color, from the liquid crystal film 6 so that both the crystal film applied portion and the non-applied portion on the dial plate I can be clearly distinguished from each other by color. On the contrary, as shown in FIG. 3, the liquid crystal film 6 may be applied only on the figure portion 2. In this case, the surface of the dial plate 1 is of course made of a material different, in color, from the liquid crystal film 6. In either case the entire surface is then covered by a transparent synthetic resin film 7 to protect the liquid crystal film 6 from damages.
The above described construction according to the present invention has the advantage that the user can enjoy a polychromic and magic beauty as he encounters various external temperature conditions.
What I claim is:
1. A polychromatic watch dial face plate with a liquid crystal film coating for varying the color of the dial face as a function of the ambient temperature, said dial face displaying a predetermined single color corresponding to a predetermined temperature, whereby the color of the dial face is indicative of the ambient temperature.
2. A polychromatic watch dial face plate as defined in claim 1 wherein said liquid crystal film coating is only on the dial face plate, the character portions of said dial face plate being free of said coating, so that said dial face changes colors with change in the abmient temperature.
3. The polychromatic watch dial face plate as defined in claim 3 wherein said liquid crystal film coating is only on the character portions of said dial face, so that said character portions only change color with change in ambient temperature.

Claims (3)

1. A polychromatic watch dial face plate with a liquid crystal film coating for varying the color of the dial face as a function of the ambient temperature, said dial face displaying a predetermined single color corresponding to a predetermined temperature, whereby the color of the dial face is indicative of the ambient temperature.
2. A polychromatic watch dial face plate as defined in claim 1 wherein said liquid crystal film coating is only on the dial face plate, the character portions of said dial face plate being free of said coating, so that said dial face changes colors with change in the ambient temperature.
3. The polychromatic watch dial face plate as defined in claim 1 wherein said liquid crystal film coating is only on the character portions of said dial face, so that said character portions only change color with change in ambient temperature.
