行ない難いものであつた。 In addition, there is a conventional method of indicating dangerous temperatures by applying a temperature-indicating paint such as thermochromic paint and observing the change in color tone of the temperature-indicating paint. The heat resistance temperature is extremely low (below 100° C.), so it cannot be used for glass plates subject to the above-mentioned high temperatures, and it is difficult to distinguish color changes.

By using a thermochromic material whose main ingredient is thallium chromate, which has heat resistance and long lifespan, it is possible to display dangerous temperatures on glass plates that reach high temperatures.
The display means is also designed to be very easy to see, so that even from the outside it can be easily identified whether or not there is a dangerous temperature condition.

As shown in Figures 1 to 3, this invention forms a black part with an appropriate pattern stamped on a part of a glass plate such as a door glass, and injects thallium chromate, which is the main component, into the black part. A thermochromic material having a temperature of 100% is applied thereto, and a yellow portion, which is the same as the normal temperature color of the thermochromic material, is formed on at least one side edge of the black portion.

According to the present invention, a thermochromic material whose main component is thallium chromate, which is heat-resistant and long-lasting, is used, so it is possible to display the dangerous temperature of a relatively high-temperature glass plate. The back color of the temperature display section is black, and the reference color for identifying color changes is yellow, which is the same as the normal temperature color of the thermochromic material, so that the yellow part is clearly displayed on the black part to the user. Therefore, it is very easy to understand, and even when the thermochromic material changes color to orange, the color tone with the reference color is vivid and the dangerous temperature display effect is great.

焼き付けされる。 Reference numeral 6 is the dangerous temperature display section of the present invention formed in the upper left corner of the glass plate 4, and a black part 7 is formed on the back side of the glass plate 4 with a suitable pattern (picture) printed with commercially available black paint. , this black part 7
A thermochromic material 8 paint containing thallium chromate (T1 2 CrO 4 ) as a main component is applied to the printed portion (pattern portion), and a thermochromic material 8 is applied to at least one edge of the black portion. 8
form a yellow part 9 (standard color) that is the same as the normal temperature color of

Since the present invention is constructed as described above, it uses a thermochromic material mainly composed of thallium chromate, which is heat resistant and has a long lifespan. In addition, by making the back color of the dangerous temperature display part black, and by making the standard color for identifying color change yellow, which is the same as the normal temperature color of the thermochromic material, the black part of the back can be displayed. As a result, the yellow part is clearly displayed, making it very easy to see, and even if the thermochromic material turns orange, the color tone with the reference color is vivid, greatly improving the dangerous temperature display effect. This can have a remarkable effect.
