Abstract

PROBLEM TO BE SOLVED: To increase commodity value by giving a bright foot light impression at a floor mat and making its pattern look variegated depending upon the color of a light source to be illuminated. SOLUTION: A floor mat 1 has a pattern 2 shown by a circle mark and a pattern 3 by a cross mark drawn in a superposed fashion as per Fig. (a). In detail, the background part 4 is black, the part 5 represented by only the pattern 2 of the circle mark is green, the part 6 by only the pattern 3 of the cross mark is red and the part 7 where the pattern 2 of the circle mark and the pattern 3 of the cross mark are superposed over each other, is yellow. When the green LED is illuminated, the part 5 of green and the part 7 of yellow look green, reflecting a green light and the part 6 of red looks black, negating the light of the green LED, so that the part 6 of red can no longer be distinguished from the part 4 of black, as per Fig. (b). Thus only the pattern 2 of the circle mark looms sharply green. When the red LED is illuminated, the part 6 of red and the part 7 of yellow reflect the light of red, making only the pattern 3 of the cross mark loom sharply red, as per Fig. (c).

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor mat for an automobile or the like, and more particularly, to a floor mat in which a pattern seen varies depending on the color of a light source to be illuminated.

[0002]

2. Description of the Related Art Hitherto, indoor lighting of automobiles has a small amount of light, and it has not been possible to illuminate a passenger's feet brightly.
As an option, there is a foot light such as a foot light. However, since floor mats are often dark colors such as black and gray, which easily absorb light, even if the foot light is turned on, the feet do not feel too bright. In addition, there is a floor mat on which a pattern such as a character or a picture is drawn, but a floor mat in which the pattern seen depending on the color of the light source to be illuminated has not been realized.

[0003]

SUMMARY OF THE INVENTION Therefore, the present invention provides a floor mat which can make the feet feel brighter and can improve the commercial value by changing the pattern seen by the color of the illuminated light source. The task is to do so.

[0004]

A floor mat according to the first aspect of the present invention is illuminated by a light source having two different emission colors having substantially a single wavelength, thereby displaying two types of symbols. A floor mat, wherein a first symbol displayed when illuminated by a first light source and a second symbol displayed when illuminated by a second light source among the light sources overlap each other, and The portion of the surface pattern of the floor mat drawn on the surface of the floor mat and the portion of the first pattern only is the same color as the first light source, and the portion of the second pattern only Is the same color as the second light source, and the portion where the first symbol and the second symbol overlap can reflect both the light from the first light source and the light from the second light source Color, the rest absorb light from each light source It is those that are that color.

[0005] The colored floor mats are
When illuminated by the light source, the portion of only the first symbol has the same color as the first light source, so the light of the first light source is reflected. Since the portion of the second symbol only has the same color as the second light source, The light from the first light source does not reflect and looks black, and the portion where the first symbol and the second symbol overlap is a color that can reflect both the light from the first light source and the second light source. Because of this, the light from the first light source is reflected, and the other portions appear black because they absorb light from each light source. As a result, the portion where only the first symbol and the portion where the first symbol and the second symbol overlap are the first symbol.
Since the light of the light source is reflected and looks shining, and the other part looks black, the first symbol clearly appears on the black background with the emission color of the first light source. In this way, the first symbol is displayed by being illuminated by the first light source.

On the other hand, when this floor mat is illuminated with the second light source, the portion of the second symbol only has the same color as the second light source, so that the light of the second light source is reflected, Since only the pattern is the same color as the first light source, it looks black without reflecting the light of the second light source, and the portion where the first and second patterns overlap is the first light source. Since the color can reflect both light from the second light source, the light from the second light source is reflected,
The other portions appear black because they absorb light from each light source. As a result, only the second symbol portion and the first symbol
The portion where the symbol of the second symbol overlaps the second symbol reflects the light of the second light source and appears to be shining, and the other portions appear black, so that the second symbol is displayed on a black background. Vividly emerges with the emission color of the second light source. In this manner, the second symbol is displayed by being illuminated by the second light source.

[0007] In this way, by changing the color of the light emitted from the light source illuminating the floor mat, the pattern seen can be changed into two types, giving the viewer unexpectedness and improving the commercial value. Then, the first symbol transmits the light of the first light source to the second symbol.
Since the pattern of (2) vividly reflects the light of the second light source, the periphery of the floor mat is felt bright.

[0008] In this way, the floor mat can make the feet feel brighter and the design seen by the color of the illuminated light source changes, thereby improving the commercial value.

[0009] The floor mat according to the invention of claim 2 is:
In the configuration of claim 1, the emission color of the light source is red,
The color is selected from green and blue.

In a floor mat having such a configuration, there are three types of combinations of light sources of two colors to be illuminated. Among them, a case where a first light source is a green light source and a second light source is a red light source will be described. Of the portions where the first symbol is drawn, the portion of only the first symbol without overlapping with the second symbol is green, and the portion where the first symbol and the second symbol overlap is green and red. It is yellow that can reflect light together, the portion of only the second symbol is red, and the other portions are black.

The floor mat colored in this way is the first
When illuminated with a green light source, which is a light source, the green part reflects green light as it is and looks green, and the yellow part is a color that can reflect both green and red light, so it is a color close to green Is reflected and looks green. On the other hand, since the red portions are primary colors, they cancel each other out with green light and appear black. Further, the black portion also absorbs the light from the green light source and looks black as it is. Therefore, the portion of only the second symbol is indistinguishable from the background color of black, and only the first symbol emerges vividly in green.
In this way, the first symbol is displayed by being illuminated by the first light source.

On the other hand, when this floor mat is illuminated by a second light source, a red light source, the red portion reflects the red light as it is and looks red, and the yellow portion also emits the red and green light. Since both colors can be reflected, light of a color close to red is reflected and looks red. On the other hand, the green portions are mutually primary colors and therefore cancel each other out with the red light and appear black. Further, the black portion also absorbs the light from the red light source and looks black as it is. Therefore, the portion of only the first symbol is indistinguishable by being integrated with the background color of black, and only the second symbol emerges vividly in red. In this manner, the second symbol is displayed by being illuminated by the second light source.

[0013] This phenomenon is that even when the two light sources are a green light source and a blue light source or a red light source and a blue light source, the portion where the pattern of the floor mat is drawn is colored in two primary colors, intermediate colors thereof and black. Doing so happens as well. For this reason, the pattern seen by changing the color which illuminates the floor mat changes into two types, giving unexpectedness to the viewer and improving the commercial value. Since the first symbol reflects the light of the first light source and the second symbol reflects the light of the second light source, the periphery of the floor mat is felt bright.

In this manner, the floor mat can make the feet feel brighter and the design seen by the color of the light source illuminated changes, thereby improving the commercial value.

[0015] The floor mat according to the invention of claim 3 is:
A floor mat on which three kinds of symbols are displayed by being illuminated by light sources having three different emission colors having substantially a single wavelength, and a floor mat displayed when illuminated by a first light source. The first symbol, the second symbol displayed when illuminated by the second light source, and the third symbol displayed when illuminated by the third light source overlap and are drawn on the surface of the floor mat. The portion where only the first pattern is drawn is the same color as the first light source, and the portion where only the second pattern is formed is the second pattern. Is the same color as the light source, and the portion of only the third symbol is the same color as the third light source, and the portion where the first symbol and the second symbol overlap is the first light source. A color that can reflect only the light of the second light source and the second symbol and the front The portion where the third symbol overlaps is a color capable of reflecting only the light of the second light source and the third light source, and the portion where the first symbol and the third symbol overlap is A color in which only the light of the first light source and the light of the third light source can be reflected, and a portion where the first symbol, the second symbol, and the third symbol are all overlapped is the first symbol. The light source, the light from the second light source and the light from the third light source are all colors that can be reflected, and the other parts are colors that absorb all the light from each light source.

When the floor mat thus colored is illuminated by the first light source, only the first design portion,
The portion where the first symbol and the second symbol overlap, the portion where the first symbol and the third symbol overlap, and the portion where all three symbols overlap are all the first light source. Is reflected, the light appears to be shining in the emission color of the first light source.
On the other hand, the portion including only the second symbol, the portion including only the third symbol, the portion where the second symbol overlaps with the third symbol, and the other portions are all the first light source. It does not reflect light, so it looks black. As a result, the first symbol appears vividly in the luminescent color of the first light source on a black background. In this way, the first symbol is displayed by being illuminated by the first light source.

When the floor mat is illuminated by the second light source, a portion of only the second symbol, a portion where the second symbol and the first symbol overlap, a portion of the second symbol and the second symbol, The portion where the symbol 3 overlaps and the portion where all three symbols overlap all reflect the light of the second light source, and thus appear to shine with the emission color of the second light source. On the other hand, the portion of only the first symbol, the portion of only the third symbol, the portion where the first symbol and the third symbol overlap, and the other portions are all the second light source. It does not reflect light, so it looks black. As a result, the second symbol appears vividly on the black background with the emission color of the second light source. In this way, the second symbol is displayed by being illuminated by the second light source.

Further, when this floor mat is illuminated by a third light source, a portion of only the third symbol, a portion where the third symbol and the first symbol overlap, a portion of the third symbol and the third symbol are illuminated. 2
The portion where the symbol overlaps with the symbol and the portion where all three symbols overlap all reflect the light of the third light source, and thus appear to shine with the emission color of the third light source. On the other hand, the first light source only, the second light source only, the portion where the first and second symbols overlap, and the other portions are all third light sources. It does not reflect light, so it looks black. As a result, the third symbol appears vividly in the emission color of the third light source on a black background. In this way, the third symbol is displayed by being illuminated by the third light source.

As described above, the floor mat according to the present invention is illuminated by the first light source, the second light source, and the third light source, and displays three types of designs. In addition, unexpectedness can be felt. Thereby, the commercial value can be further improved. And the first symbol is the light of the first light source,
Since the second symbol reflects the light of the second light source and the third symbol reflects the light of the third light source, respectively, the periphery of the floor mat is felt bright.

[0020] In this way, the floor mat can be made to feel brighter at the feet, and the pattern seen by the color of the illuminated light source changes to three types, thereby providing a floor mat that can further improve the commercial value.

The floor mat according to the invention of claim 4 is:
In the configuration of claim 3, the emission color of the light source is red,
It consists of green and blue.

In the floor mat according to the present invention,
Of the part where the design of the surface of the floor mat is drawn, the first
Is a red light of the same color as the red light source as the first light source, a portion of the second design is a green light of the same color as the green light source as the second light source, and only the third The portion is blue of the same color as the blue light source which is the third light source, and the portion where the first symbol and the second symbol overlap is yellow which can reflect only the light of the red and green light sources, and the second symbol. The portion where the third symbol overlaps with the third symbol is light blue capable of reflecting only the light of the green light source and the blue symbol, and the portion where the first symbol and the third symbol overlap is a red light source and a blue light source. Red light that can reflect only light of the first symbol, the second symbol, and the third symbol.
Are all white, which can reflect all the light from the red light source, the green light source, and the blue light source, and the other portions are black, which absorbs all the light from each light source.

Here, in this specification, "purple purple"
Is a bright red purple color close to pink.

When the floor mat having such a configuration is illuminated with a red light source, the red portion is reflected as it is and the red light is reflected, and the green portion and the blue portion cancel each other out because they are primary colors. Together they look black.
Since the yellow portion is a color that can reflect only the light of the red light source and the green light source, light of a color close to red is reflected and looks red. Similarly, since the red-violet portion is a color that can reflect only the light from the red light source and the blue light source, light of a color close to red is reflected and looks red. On the other hand, the light blue portion is an intermediate color between green and blue and therefore has a complementary color of red, and cancels out the red light to appear black. Further, the black portion looks red because it absorbs red light, and the white portion looks red because it reflects red light as it is.

As a result, the green portion, the blue portion, and the light blue portion, that is, the portion of only the second symbol, the portion of only the third symbol, and only the second symbol and the third symbol overlap. Each part becomes unidentifiable by being integrated with the black part which is the background color. On the other hand, other portions, that is, a portion of only the first symbol, a portion where the first symbol and the second symbol overlap, a portion where the first symbol and the third symbol overlap, and three portions Since all the portions where the symbols are all overlapped appear red, only the first symbol appears to be vividly displayed in red on a black background. Thus, the first symbol is displayed on the surface of the floor mat by being illuminated by the red light source.

When the floor mat having such a structure is illuminated with a green light source, the green portion is reflected as it is and the green light is reflected to appear green. The blue and red portions are primary colors, so that the green light is And appear black. Since the yellow portion is a color that can reflect only the light of the red light source and the green light source, light of a color close to green is reflected and looks green. Similarly, the light blue portion is a color that can reflect only the light of the blue light source and the green light source, so that light of a color close to green is reflected and looks green. On the other hand, the magenta part is a complementary color of green because it is an intermediate color between red and blue,
It appears to be black, canceling out the green light. Furthermore, the black part looks green as it is because it absorbs green light,
The white portion looks green because it reflects green light as it is.

As a result, the red portion, the blue portion, and the magenta portion, that is, only the first symbol portion, the third symbol portion, and only the first symbol and the third symbol overlap. Any part that is present becomes unidentifiable by being integrated with the black part that is the background color. On the other hand, other portions, that is, a portion of only the second symbol, a portion where the second symbol and the first symbol overlap, a portion where the second symbol and the third symbol overlap, and three portions Since all the portions where the symbols are all overlapped appear green, only the second symbol appears vividly green on the black background. In this way, the second symbol is displayed on the surface of the floor mat by being illuminated by the green light source.

Further, when the floor mat having such a configuration is illuminated with a blue light source, the blue portion is reflected as it is and the blue light is reflected, and the red portion and the green portion are primary colors. And appear black. Since the light blue portion is a color that can reflect only the light of the blue light source and the green light source, light of a color close to blue is reflected and looks blue. Similarly, since the red-violet portion is a color that can reflect only the light of the blue light source and the red light source, light of a color close to blue is reflected and looks blue. On the other hand, since the yellow portion is a color intermediate between red and green, it becomes a complementary color of blue and cancels out blue light to appear black. further,
The black portion looks blue because it absorbs blue light, and the white portion looks blue because it reflects blue light as it is.

As a result, the red portion, the green portion, and the yellow portion, ie, only the first symbol portion, the second symbol portion, and the first symbol and the second symbol only overlap. Each part becomes unidentifiable by being integrated with the black part which is the background color. On the other hand, other portions, that is, a portion of only the third symbol, a portion where the third symbol and the second symbol overlap, a portion where the third symbol and the first symbol overlap, and three portions Since all the portions where the symbols are all overlapped appear blue, only the third symbol appears to be vividly blue on the black background. In this way, the third symbol is displayed on the surface of the floor mat by being illuminated by the blue light source.

As described above, the floor mat according to the present invention is illuminated by the red light source, the green light source, and the blue light source, so that three kinds of designs are displayed. be able to. Thereby, the commercial value can be further improved. The first symbol is light of a red light source, the second symbol is light of a green light source, the third symbol is light of a blue light source,
Each area reflects vividly, so the area around the floor mat is bright.

In this way, the floor mat can be made to feel brighter at the feet, and the pattern seen depending on the color of the illuminated light source changes to three types, thereby providing a floor mat that can further improve the commercial value.

Only the symbol 13 with a cross mark appears to be vividly raised in red. In this way, by being illuminated by the red light source, a symbol 13 as a first symbol is displayed on the surface of the floor mat 11.

Further, the floor mat 11 shown in FIG.
Is illuminated by a blue LED as a blue light source similarly attached to the lower front end of the seat, the blue portion 18 of the surface of the floor mat 11 reflects blue light as it is and looks blue, and the red portion Since 17 and the green portion 16 are primary colors, they cancel each other out with blue light and appear black. Since the light blue portion 20 is a color that can reflect only blue and green light, light of a color close to blue is reflected and looks blue. Similarly, since the red-purple portion 21 is a color that can reflect only blue and red light, light of a color close to blue is reflected and looks blue. On the other hand, since the yellow portion 19 is an intermediate color between red and green, it becomes a complementary color of blue as shown in FIG. 3 and cancels out the blue light to appear black. Furthermore, the black portion 15 looks blue because it absorbs blue light, and the white portion 22 looks blue because it reflects blue light as it is.

[0082]

As described above, the floor mat according to the first aspect of the present invention is illuminated by the light sources having two different emission colors having substantially the same wavelength.
A floor mat on which two types of symbols are displayed, wherein a first symbol displayed when illuminated by a first light source and a second symbol displayed when illuminated by a second light source. 2 is overlapped and drawn on the surface of the floor mat, and among the portions on which the design of the surface of the floor mat is drawn, the portion of only the first design is the same color as the first light source. Yes, the portion of only the second symbol is the second symbol
Is the same color as the light source, and the portion where the first symbol and the second symbol overlap is a color capable of reflecting both the light from the first light source and the light from the second light source. Is a color that absorbs light from each light source.

The colored floor mats are
When illuminated by the light source, the portion of only the first symbol has the same color as the first light source, so the light of the first light source is reflected. Since the portion of the second symbol only has the same color as the second light source, The light from the first light source does not reflect and looks black, and the portion where the first symbol and the second symbol overlap is a color that can reflect both the light from the first light source and the second light source. Because of this, the light from the first light source is reflected, and the other portions appear black because they absorb light from each light source. As a result, the portion where only the first symbol and the portion where the first symbol and the second symbol overlap are the first symbol.
Since the light of the light source is reflected and looks shining, and the other part looks black, the first symbol clearly appears on the black background with the emission color of the first light source. In this way, the first symbol is displayed by being illuminated by the first light source.

On the other hand, when this floor mat is illuminated by the second light source, the portion of only the second symbol has the same color as the second light source, so that the light of the second light source is reflected, Since only the pattern is the same color as the first light source, it looks black without reflecting the light of the second light source, and the portion where the first and second patterns overlap is the first light source. Since the color can reflect both light from the second light source, the light from the second light source is reflected,
The other portions appear black because they absorb light from each light source. As a result, only the second symbol portion and the first symbol
The portion where the symbol of the second symbol overlaps the second symbol reflects the light of the second light source and appears to be shining, and the other portions appear black, so that the second symbol is displayed on a black background. Vividly emerges with the emission color of the second light source. In this manner, the second symbol is displayed by being illuminated by the second light source.

As described above, by changing the color of the light emitted from the light source illuminating the floor mat, the pattern seen can be changed into two types, thereby giving the viewer unexpectedness and improving the commercial value. Then, the first symbol transmits the light of the first light source to the second symbol.
Since the pattern of (2) vividly reflects the light of the second light source, the periphery of the floor mat is felt bright.

In this way, the floor mat can make the feet feel brighter and the design seen by the color of the light source illuminated changes, thereby improving the commercial value.

The floor mat according to the second aspect of the present invention
In the configuration of claim 1, the emission color of the light source is red,
The color is selected from green and blue.

In the floor mat having such a configuration, there are three types of combinations of light sources of two colors to be illuminated. Among them, a case where the first light source is a green light source and the second light source is a red light source will be described. Of the portions where the first symbol is drawn, the portion of only the first symbol without overlapping with the second symbol is green, and the portion where the first symbol and the second symbol overlap is green and red. It is yellow that can reflect light together, the portion of only the second symbol is red, and the other portions are black.

The colored floor mats are
When illuminated with a green light source, which is a light source, the green part reflects green light as it is and looks green, and the yellow part is a color that can reflect both green and red light, so it is a color close to green Is reflected and looks green. On the other hand, since the red portions are primary colors, they cancel each other out with green light and appear black. Further, the black portion also absorbs the light from the green light source and looks black as it is. Therefore, the portion of only the second symbol is indistinguishable from the background color of black, and only the first symbol emerges vividly in green.
In this way, the first symbol is displayed by being illuminated by the first light source.

On the other hand, when this floor mat is illuminated with the red light source, which is the second light source, the red portion reflects the red light as it is and looks red, and the yellow portion also emits the red and green light. Since both colors can be reflected, light of a color close to red is reflected and looks red. On the other hand, the green portions are mutually primary colors and therefore cancel each other out with the red light and appear black. Further, the black portion also absorbs the light from the red light source and looks black as it is. Therefore, the portion of only the first symbol is indistinguishable by being integrated with the background color of black, and only the second symbol emerges vividly in red. In this manner, the second symbol is displayed by being illuminated by the second light source.

This phenomenon is that even when the two light sources are a green light source and a blue light source or a red light source and a blue light source, the portion where the pattern of the floor mat is drawn is colored in the two primary colors, intermediate colors thereof, and black. Doing so happens as well. For this reason, in addition to the effect described in claim 1, by changing the color illuminating the floor mat into two different designs, the viewer is given unexpectedness and the commercial value is improved. Then, the first symbol transmits the light of the first light source to the second symbol.
Since the pattern of (2) vividly reflects the light of the second light source, the periphery of the floor mat is felt bright.

In this way, the floor mat can make the feet feel brighter, and the design seen by the color of the illuminated light source changes, thereby improving the commercial value.

The floor mat according to the third aspect of the present invention
A floor mat on which three kinds of symbols are displayed by being illuminated by light sources having three different emission colors having substantially a single wavelength, and a floor mat displayed when illuminated by a first light source. The first symbol, the second symbol displayed when illuminated by the second light source, and the third symbol displayed when illuminated by the third light source overlap and are drawn on the surface of the floor mat. The portion where only the first pattern is drawn is the same color as the first light source, and the portion where only the second pattern is formed is the second pattern. Is the same color as the light source, and the portion of only the third symbol is the same color as the third light source, and the portion where the first symbol and the second symbol overlap is the first light source. A color that can reflect only the light of the second light source and the second symbol and the front The portion where the third symbol overlaps is a color capable of reflecting only the light of the second light source and the third light source, and the portion where the first symbol and the third symbol overlap is A color in which only the light of the first light source and the light of the third light source can be reflected, and a portion where the first symbol, the second symbol, and the third symbol are all overlapped is the first symbol. The light source, the light from the second light source and the light from the third light source are all colors that can be reflected, and the other parts are colors that absorb all the light from each light source.

When the colored floor mats are illuminated by the first light source, only the first design portion,
The portion where the first symbol and the second symbol overlap, the portion where the first symbol and the third symbol overlap, and the portion where all three symbols overlap are all the first light source. Is reflected, the light appears to be shining in the emission color of the first light source.
On the other hand, the portion including only the second symbol, the portion including only the third symbol, the portion where the second symbol overlaps with the third symbol, and the other portions are all the first light source. It does not reflect light, so it looks black. As a result, the first symbol appears vividly in the luminescent color of the first light source on a black background. In this way, the first symbol is displayed by being illuminated by the first light source.

When the floor mat is illuminated with the second light source, the portion of the second symbol only, the portion where the second symbol and the first symbol overlap, and the portion of the second symbol and the second symbol are illuminated. The portion where the symbol 3 overlaps and the portion where all three symbols overlap all reflect the light of the second light source, and thus appear to shine with the emission color of the second light source. On the other hand, the portion of only the first symbol, the portion of only the third symbol, the portion where the first symbol and the third symbol overlap, and the other portions are all the second light source. It does not reflect light, so it looks black. As a result, the second symbol appears vividly on the black background with the emission color of the second light source. Thus, the second symbol is displayed by being illuminated by the second light source.

Further, when this floor mat is illuminated by the third light source, a portion of only the third symbol, a portion where the third symbol and the first symbol overlap, and a portion of the third symbol and the third symbol are illuminated. 2
The portion where the symbol overlaps with the symbol and the portion where all three symbols overlap all reflect the light of the third light source, and thus appear to shine with the emission color of the third light source. On the other hand, the first light source only, the second light source only, the portion where the first and second symbols overlap, and the other portions are all third light sources. It does not reflect light, so it looks black. As a result, the third symbol appears vividly in the emission color of the third light source on a black background. In this way, the third symbol is displayed by being illuminated by the third light source.

As described above, the floor mat according to the present invention is illuminated by the first light source, the second light source, and the third light source, and displays three types of designs. In addition, unexpectedness can be felt. Thereby, the commercial value can be further improved. And the first symbol is the light of the first light source,
Since the second symbol reflects the light of the second light source and the third symbol reflects the light of the third light source, respectively, the periphery of the floor mat is felt bright.

In this way, the floor mat can be made to feel brighter at the feet and the pattern seen by the color of the illuminated light source can be changed to three types, thereby providing a floor mat that can further improve the commercial value.

The floor mat according to the invention of claim 4 is:
In the configuration of claim 3, the emission color of the light source is red,
It consists of green and blue.

In the floor mat according to the present invention,
Of the part where the design of the surface of the floor mat is drawn, the first
Is a red light of the same color as the red light source as the first light source, a portion of the second design is a green light of the same color as the green light source as the second light source, and only the third The portion is blue of the same color as the blue light source which is the third light source, and the portion where the first symbol and the second symbol overlap is yellow which can reflect only the light of the red and green light sources, and the second symbol. The portion where the third symbol overlaps with the third symbol is light blue capable of reflecting only the light of the green light source and the blue symbol, and the portion where the first symbol and the third symbol overlap is a red light source and a blue light source. Red light that can reflect only light of the first symbol, the second symbol, and the third symbol.
Are all white, which can reflect all the light from the red light source, the green light source, and the blue light source, and the other portions are black, which absorbs all the light from each light source.

When the floor mat having such a structure is illuminated with a red light source, the red portion is reflected as it is and the red light is reflected to appear red. Together they look black.
Since the yellow portion is a color that can reflect only the light of the red light source and the green light source, light of a color close to red is reflected and looks red. Similarly, since the red-violet portion is a color that can reflect only the light from the red light source and the blue light source, light of a color close to red is reflected and looks red. On the other hand, the light blue portion is an intermediate color between green and blue and therefore has a complementary color of red, and cancels out the red light to appear black. Further, the black portion looks red because it absorbs red light, and the white portion looks red because it reflects red light as it is.

As a result, the green portion, the blue portion, and the light blue portion, that is, the portion of only the second symbol, the portion of only the third symbol, and only the second symbol and the third symbol overlap. Each part becomes unidentifiable by being integrated with the black part which is the background color. On the other hand, other portions, that is, a portion of only the first symbol, a portion where the first symbol and the second symbol overlap, a portion where the first symbol and the third symbol overlap, and three portions Since all the portions where the symbols are all overlapped appear red, only the first symbol appears to be vividly displayed in red on a black background. Thus, the first symbol is displayed on the surface of the floor mat by being illuminated by the red light source.

When the floor mat having the above configuration is illuminated with a green light source, the green portion is reflected as it is and the green light is reflected, and the blue portion and the red portion are primary colors. And appear black. Since the yellow portion is a color that can reflect only the light of the red light source and the green light source, light of a color close to green is reflected and looks green. Similarly, the light blue portion is a color that can reflect only the light of the blue light source and the green light source, so that light of a color close to green is reflected and looks green. On the other hand, the magenta part is a complementary color of green because it is an intermediate color between red and blue,
It appears to be black, canceling out the green light. Furthermore, the black part looks green as it is because it absorbs green light,
The white portion looks green because it reflects green light as it is.

As a result, the red portion, the blue portion, and the magenta portion, that is, the portion of the first symbol only, the portion of the third symbol only, and only the first symbol and the third symbol overlap. Any part that is present becomes unidentifiable by being integrated with the black part that is the background color. On the other hand, other portions, that is, a portion of only the second symbol, a portion where the second symbol and the first symbol overlap, a portion where the second symbol and the third symbol overlap, and three portions Since all the portions where the symbols are all overlapped appear green, only the second symbol appears vividly green on the black background. In this way, the second symbol is displayed on the surface of the floor mat by being illuminated by the green light source.

Further, when the floor mat having such a configuration is illuminated with a blue light source, the blue portion is reflected as it is and the blue light is reflected, and the red portion and the green portion are mutually primary colors. And appear black. Since the light blue portion is a color that can reflect only the light of the blue light source and the green light source, light of a color close to blue is reflected and looks blue. Similarly, since the red-violet portion is a color that can reflect only the light of the blue light source and the red light source, light of a color close to blue is reflected and looks blue. On the other hand, since the yellow portion is a color intermediate between red and green, it becomes a complementary color of blue and cancels out blue light to appear black. further,
The black portion looks blue because it absorbs blue light, and the white portion looks blue because it reflects blue light as it is.

As a result, the red portion, the green portion, and the yellow portion, ie, the first symbol only portion, the second symbol only portion, and the first symbol and the second symbol only overlap. Each part becomes unidentifiable by being integrated with the black part which is the background color. On the other hand, other portions, that is, a portion of only the third symbol, a portion where the third symbol and the second symbol overlap, a portion where the third symbol and the first symbol overlap, and three portions Since all the portions where the symbols are all overlapped appear blue, only the third symbol appears to be vividly blue on the black background. In this way, the third symbol is displayed on the surface of the floor mat by being illuminated by the blue light source.

As described above, the floor mat according to the present invention, in addition to the effect described in claim 3, displays three types of designs by being illuminated by the red light source, the green light source, and the blue light source, respectively. Therefore, the viewer can be made to feel more unexpected. Thereby, the commercial value can be further improved. And the first symbol is the light of the red light source, the second symbol is the light of the green light source,
Since the third symbol reflects the light of the blue light source vividly, the periphery of the floor mat is felt bright.

[0108] In this way, the floor mat can be made to feel brighter at the feet, and the pattern seen depending on the color of the illuminated light source can be changed to three types, thereby providing a floor mat that can further improve the commercial value.
