Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
FIG. 1 is a view for explaining a laminated glass 100 for a vehicle according to the present embodiment.
The laminated glass 100 for a vehicle shown in FIG. 1 is provided with a band-shaped blur 22 (see the upper right oblique line portion in FIG. 1) near the upper edge. The blur 22 is provided on each of the left and right sides of the laminated glass 100 for a vehicle.
The blur 22 is for reducing the driver's feeling of dazzling sunlight such as the sun or sunset, and suppresses the transmission of visible light.
In addition, as will be described later, the laminated glass for a vehicle 100 has a region that suppresses the temperature rise in the vehicle due to sunlight by suppressing the transmission of sunlight (see the coating 11a in FIG. 3A). ).

  Further, a non-transmissive region 32 that does not transmit light (refer to the hatched portion at the lower right in FIG. 1) is formed at the peripheral portion of the laminated glass 100 for a vehicle. The impermeable area 32 is a margin for bonding the laminated glass 100 for a vehicle to the vehicle body, and a black ceramic 32a (see FIG. 3C) is applied to hide the adhesive.

In addition, an opaque region 33 (see the lower right hatched portion in FIG. 1) that is continuous with the above-described opaque region 32 is formed in the upper center of the laminated glass 100 for a vehicle. The opaque region 33 is located between the left blur 22 and the right blur 22.
Further, a dot portion 34 (see the range with the dots in FIG. 1) is formed between the opaque region 33 and the left blur 22, and a dot portion is also formed between the opaque region 33 and the right blur 22. 34 is formed.
As described above, in the upper part of the laminated glass 100 for a vehicle, the opaque region 33 is located in the center, the dot portions 34 are located on the outer sides in the left-right direction, and the blurs 22 are located on the outer sides in the left-right direction.
In the present embodiment, the impermeable region 33 is located at the center in the left-right direction. In this embodiment, the dot portion 34 does not overlap the blur 22, but a part of the dot portion 34 may overlap the blur 22.

The laminated glass 100 for vehicles is formed with an opening 35 formed by cutting out a part of the impermeable region 33. The opening 35 can be used as, for example, a hole for a sensor (not shown) of the brake support device, and has a higher light transmittance than other portions of the laminated glass 100 for a vehicle.
The opening 35 is formed in a trapezoidal shape having a lower bottom longer than the upper bottom. The bracket of the sensor is prevented from being reflected on the laminated glass 100 for the vehicle, and the operation of the brake support device is prevented from being affected. The opening 35 has a symmetrical trapezoidal shape, but may be an asymmetric trapezoidal shape.
In the present embodiment, the upper bottom of the opening 35 is located above the lower end of the blur 22, and the lower bottom is located below the lower end of the blur 22. The blur 22 is formed so as to become thinner toward the lower end, and the lower end position of the blur 22 is not clear. good. By making the opening 35 as high as possible on the laminated glass 100 for the vehicle, it is possible to reduce the possibility that the brake support sensor may obstruct the driver's view.

FIG. 2 is an exploded perspective view of laminated glass 100 for vehicle according to the present embodiment. FIG. 3 is a diagram for explaining the vehicle-side glass plate 1, the intermediate film 2, and the vehicle-side glass plate 3 provided in the laminated glass 100 for a vehicle according to the present embodiment, and (a) is a line A in FIG. -B is a cross-sectional view of the vehicle-side glass plate 1 taken along line A-B in Fig. 2, and (c) is a cross-sectional view of the vehicle-side glass plate 3 taken along line BB in Fig. 2. .
As shown in FIG. 2, the laminated glass 100 for a vehicle includes an outside glass plate 1, an intermediate film 2, and an inside glass plate 3. The vehicle-side glass plate 1 and the vehicle-side glass plate 3 are bonded via an intermediate film 2. The vehicle exterior glass plate 1 and the vehicle interior glass plate 3 are examples of glass plates, and the intermediate film 2 is an example of an intermediate film.

The vehicle exterior glass plate 1 is subjected to a process of reflecting infrared light and suppressing transmission. The infrared light referred to here is an electromagnetic wave having a longer wavelength than that of visible light red and a shorter wavelength than radio waves.
Such infrared light transmission suppression processing is performed over almost the entire surface of the vehicle exterior glass plate 1, but there are places where it is not applied. Specifically, the vehicle exterior glass plate 1 has a region 11 where infrared light transmission suppression processing is performed and heat of infrared light is not allowed to enter the vehicle, and a region where infrared light transmission suppression processing is not performed. I have twelve. The region 12 is located at the center in the left-right direction at the upper part of the vehicle exterior glass plate 1. The region 12 is formed in an inverted trapezoidal shape in which the lower side is shorter than the upper side and is substantially symmetrical.
In this embodiment, infrared light transmission is suppressed by reflecting infrared light. However, the present invention is not limited to this, and infrared light absorption is suppressed to suppress infrared light transmission. You may make it do.

More specifically, as shown in FIG. 3 (a), the infrared light transmission suppressing process for the vehicle outer side glass plate 1 is performed by applying a coating 11a on the inner side 1b instead of the outer surface 1a. In FIG. 3 (a), the coating 11a is illustrated away from the vehicle exterior glass plate 1, but this is a conceptual view, and the coating 11a is actually applied to the inner side 1b.
Such coating 11a is subjected to vapor deposition of metal powder. By such a coating 11a, the laminated glass 100 for vehicles looks a color different from usual, and can give fashion. On the other hand, when the coating 11a is applied, radio waves are reflected in addition to infrared light, which affects electronic devices such as an in-vehicle television. Therefore, the coating 11a is not applied to the entire surface of the vehicle exterior glass plate 1. Thus, a part is removed (region 12 in FIG. 2).

In the present embodiment, the region 12 of the vehicle exterior glass plate 1 is located at the center in the left-right direction, but is not limited to this, and may be located in either the left-right direction. Moreover, in this Embodiment, although the area | region 12 of the vehicle outer side glass plate 1 is located only in the center of the left-right direction, it is not restricted to this, You may provide the area | region 12 in positions other than the center of the left-right direction center.
The region 11 of the vehicle exterior glass plate 1 is an example of an infrared light suppression region, and the region 12 is an example of a region other than the infrared light suppression region.

As illustrated in FIG. 2, the intermediate film 2 includes a region 21 that is not colored, the above-described blur 22 that is colored, and a cutout portion 23 that is cut out. The blur 22 is also called a top shade and is formed by coloring.
More specifically, as shown in FIG. 3B, the blur 22 is provided in the left-right direction, and the intermediate film 2 having the cut-out portion 23 is formed by cutting out the central portion in the left-right direction. Yes. The blur 22 extends in a strip shape in the left-right direction. The cutout portion 23 is formed so as to correspond to the position of the region 12 of the vehicle exterior glass plate 1. For this reason, at least a part of the cut-out portion 23 is not inhibited from transmitting infrared light, and is not inhibited from transmitting visible light.

In the present embodiment, the cut-out portion 23 of the intermediate film 2 is located at the center in the left-right direction, but the present invention is not limited to this, and may be located in either the left-right direction. In the present embodiment, the cutout portion 23 of the intermediate film 2 is cut out only in the vertical direction, but the present invention is not limited to this, and the cutout portion 23 may be cut out in the vertical direction and the horizontal direction. By cutting out in the left-right direction, the width of the blur 22 becomes narrower, and the upper end position of the blur 22 becomes lower.
In the present embodiment, the lower end of the cutout portion 23 is substantially the same as the lower end of the blur 22 or below the lower end of the blur 22. However, the present invention is not limited to this. The blur 22 may remain so as to be on the top. In other words, the cutout portion 23 in the present embodiment is formed so that the band of the blur 22 is divided into left and right as shown in FIG. You may form by narrowing a width | variety.
The region where the blur 22 is provided is an example of a visible light suppression region, and the cutout portion 23 is an example of a region other than the visible light suppression region. An impermeable area 33, a dot portion 34, and an opening 35 of the vehicle interior glass plate 3 to be described later are examples of the predetermined area.

  As shown in FIG. 2, the vehicle interior glass plate 3 includes a region 31 that transmits light, and the above-described non-transmissive regions 32 and 33, a dot portion 34, and an opening 35. The opaque region 33 and the dot portion 34 are formed so as to correspond to the positions of the region 12 of the vehicle-side glass plate 1 and the cutout portion 23 of the intermediate film 2. In the present embodiment, the impermeable region 33 of the vehicle interior glass plate 3 is located at the center in the left-right direction, but the present invention is not limited to this, and may be located in either the left-right direction.

The impermeable region 32 is formed at the peripheral edge of the vehicle exterior glass plate 1. The impermeable region 33 is continuous with the impermeable region 32 and is formed to protrude downward from the upper edge of the peripheral edge.
The opaque regions 32 and 33 and the dot portion 34 are applied to the vehicle interior glass plate 3 constituting a part of the vehicle exterior glass plate 1 as shown in FIG. More specifically, the non-transmissive regions 32 and 33 and the dot portion 34 are formed in black by applying the ceramic 32a to the inner side 3b instead of the outer side 3a of the vehicle inner side glass plate 3. In FIG. 5C, the ceramic 32a is illustrated apart from the vehicle interior glass plate 3, but this is a conceptual view, and in practice, the coating 11a is applied to the inner side 3b.

The dot portion 34 is formed in a dot pattern (polka dot pattern) in which a plurality of dots are arranged. More specifically, the dot portion 34 overlaps the region 12 of the vehicle exterior glass plate 1, and radio wave interference due to the coating 11a (see FIG. 3A) hardly occurs. In the dot portion 34, radio waves are transmitted. For this reason, the dot portion 34 is used to realize reception of an ETC (Electronic Toll Collection System) installed in the vehicle.
The opening 35 does not overlap with the region of the intermediate film 2 where the blur 22 is provided, and does not overlap with the region 11 of the vehicle exterior glass plate 1 on which the coating 11a (see FIG. 3A) is applied.
The opaque region 33 is an example of an opaque region, and the dot portion 34 is an example of a specific region in which a plurality of small-shaped portions are arranged apart from each other.

  The translucency of the vehicle interior glass plate 3 will be described. In the non-transmissive regions 32 and 33 shown in FIG. 2, infrared light and visible light are hardly transmitted. Infrared light and visible light are hardly transmitted where there are dots in the dot portion 34, and infrared light and visible light are transmitted where there are no dots in the dot portion 34. In addition, infrared light and visible light are transmitted through the opening 35. For this reason, the translucency increases in the order of the opaque regions 32 and 33, the dot portion 34, and the opening 35.

FIG. 4 is an exploded perspective view of a laminated glass 100 for a vehicle according to a modification.
The modification shown in the figure is different from the present embodiment having one opening 35 in that it has two openings 35A and 35B. By providing the two openings 35A and 35B, it is possible to cope with a case where the brake support device is a dual camera.

Thus, in the present embodiment and the modification, the opening 35 or the openings 35A and 35B that do not overlap with the blur 22 are provided at the height at which the blur 22 of the laminated glass 100 for vehicles is located. It is possible to reduce the probability that the support sensor becomes an obstacle to driving visibility.
In general, the laminated glass 100 for vehicles with the coating 11a and the laminated glass 100 for vehicles with the blur 22 can improve the appearance, and can also insulate sunlight and secure visibility. . For this reason, when the windshield is replaced, there is a case where it is desired to attach the laminated glass 100 for the vehicle according to the present embodiment, etc. Since it can respond, it can respond to user needs.
