Description

[Detailed description of the invention] [Industrial field of application] A decorative device that uses a liquid crystal that changes color depending on temperature and contains a desired photograph, etc., and the liquid crystal changes color when warmed with the palm of the hand. A new decorative tool that allows you to enjoy changes due to temperature as it becomes transparent and allows you to see photos, etc.

[Prior art] There are decorative tools that use temperature-dependent color changes and refractive index changes using liquid crystals and organic compounds that exhibit color-changing properties depending on temperature. It's just being used.

There are also devices that use liquid crystals that change their refractive index and transparency, and use changes in the appearance of the underlying color as decoration.

[Problems to be solved by the invention] There is no art in merely enjoying the changes in color and appearance with a decorative tool that uses a coloring substance that changes with temperature, and the user will get tired of it after using it.

This is a decorative device that allows the user to store a desired photograph, etc., and allows the photograph, etc. to be seen through when a certain temperature is reached.

[Means for Solving the Problems] Certain liquid crystals exhibit coloration depending on temperature, and are widely used in thermometers and ornaments.

It is also known that liquid crystals and color-forming organic polymers can change their transparency at a constant temperature.

The present invention uses various liquid crystal compositions and electron-donating materials that have a transition temperature at a temperature that can be warmed with the palm of the hand, that is, around 35°C, and that exhibit high transparency at temperatures above that temperature and become opaque to light below that temperature. A color-forming colorless organic compound is used as a thin layer. A thin piece accommodating portion is provided on the back side of the thin layer, and the structure is such that the user can replace and store arbitrary photographs and the like.

Further, on the front side of the thin layer, a decorative body made of a color-forming transparent material whose color changes continuously depending on the temperature may be provided, that is, a decorative body whose color changes depending on the temperature although it is always transparent.

[Function] By warming the ornament with the palm of the hand, the pattern such as a photograph stored on the back side of the color-forming thin layer becomes transparent beyond the transition temperature of the color-forming substance in the color-forming thin layer, and becomes transparent. . Below the transition temperature, the color-forming thin layer is a colored decorative surface that cannot be seen through.

In addition, if a decorative body made of a color-forming transparent material is provided on the front side of the color-forming thin layer, the color change of the decorative body can be enjoyed at all times, and when the entire decorative device is warmed with the palm of the hand, the color change of the decorative body and the A design such as a photograph can be seen as if it is visible through the transparent decorative body.

[Embodiment] FIG. 1 is a perspective view showing an embodiment of the present invention. 1 is a color-forming thin layer made of liquid crystal. 2 is the outer frame of the decoration.

FIG. 2 is a central sectional view of the ornament shown in FIG. 1 with the back cover removed. 3 is a thin piece such as a photograph that can be replaced at will.

FIG. 3 is a central sectional view showing another embodiment. A decorative body 4 made of a color-forming transparent material is provided on the surface side of the color-forming thin layer 1. The back cover 5 can be opened and closed by a hinge 6 and can accommodate any thin piece 3.

FIG. 4 is a perspective view showing the embodiment of FIG. 3. Transparent decorative body 4 that changes color when warmed with your palm etc.
The pattern of thin piece 3 appears as if it were floating in the background.

[Effects of the invention] As shown in the examples, a color-forming liquid crystal or an organic compound that becomes transparent at a certain temperature or above, whose transition temperature is a temperature that can be warmed by body temperature, is used as a color-forming thin layer. You can store any photo etc. on the back of the pendant, and if you use it as a locket to put your lover's photo etc., even if it is just a pendant,
It is a charming ornament that, when warmed in the palm of your hand, reveals a photograph of your lover. Of course, it can hold not only photographs but any thin object, and when heated with body heat, the pattern of the thin pieces contained inside will appear.

Furthermore, if a color-forming transparent substance is provided on the surface of the color-forming thin layer as a decoration in the shape of a jewel, you can enjoy the color change depending on the temperature of the transparent substance, and when a certain transition temperature is reached, the internal The design of the thin flakes housed in the paper appears to stand out.

Claims (1)

[Claims for Utility Model Registration] (1) A liquid crystal or organic compound that exhibits coloration depending on temperature is used as a coloring thin layer that becomes transparent at a certain temperature or above, and a photograph, etc. is placed on the back of the coloring thin layer. This decorative device is characterized in that it is provided with a desired thin piece storage part and that the pattern of the thin pieces, which can be replaced and housed at will by the user, becomes visible when the pattern reaches a certain temperature that can be warmed by body temperature. (2) A decoration made of a color-changing transparent material that changes color depending on the temperature is provided on the surface side of the color-changing thin layer that becomes transparent at a certain temperature or higher in the decorative device described in paragraph 1,
A decorative device characterized in that a pattern of flakes housed inside the decorative device becomes visible through the color-changing transparent material when the decorative device reaches a certain temperature that can be warmed by body heat.
