「技術分野」
本考案は、自動車のガラス窓において太陽光の
遮断、透過を任意に行えるようにした自動車用遮
光ガラス窓に関する。[Detailed Description of the Invention] [Technical Field] The present invention relates to a light-shielding glass window for an automobile that can arbitrarily block or transmit sunlight in the glass window of an automobile.
「技術分野およびその問題点」
自動車を運転中、進行方向から太陽光等が差し
込んでドライバーを眩惑させ、運転に支障をきた
すことがある。このため、自動車のフロントガラ
スには、その上部に日除けの板を回転自在に取付
けたサンバイザーが設けられている。``Technical field and its problems'' While driving a car, sunlight or other light may shine in from the direction of travel, dazzling the driver and causing difficulty in driving. For this reason, the windshield of an automobile is provided with a sun visor, in which a sunshade plate is rotatably attached to the upper part of the windshield.
しかしながら、サンバイザーにおいては、視界

内空間が狭くなつた印象を与え、心理的な圧追感
を与える。このため、サンバイザーはあまり大き
くすることができず、遮光効果が充分に得られな
かつた。 However, sun visors completely block your field of vision, so if they are made large enough to provide a sufficient light-blocking effect, it will give the impression that the interior space of the car is narrower, creating a psychological sensation of pressure. give. For this reason, the sun visor could not be made very large, and a sufficient light shielding effect could not be obtained.
「考案の目的」
本考案の目的は、少なくとも車内における視界
を遮断することなく、太陽光の遮断、透過を任意
に行えるようにした自動車用遮光ガラス窓を提供
することにある。"Purpose of the invention" The purpose of the invention is to provide a light-shielding glass window for an automobile that can arbitrarily block or transmit sunlight without blocking at least the view inside the car.
「考案の構成」
本考案の自動車用遮光ガラス窓は、自動車のガ
ラス窓の少なくとも一部に偏光フイルムを設け、
この偏光フイルムとクロスニコルになるように車
内側に偏光板を重層可能に取付けたことを特徴と
する。"Structure of the invention" The automotive light-shielding glass window of the invention includes a polarizing film provided on at least a part of the automotive glass window,
The present invention is characterized in that a polarizing plate is attached to the inside of the vehicle so that it can be layered with this polarizing film so as to form a cross nicol.

In addition, 15
is a frame that supports the polarizing plate 13. The polarizing plate 13 has polarization characteristics in the direction shown by A in FIG. 2, and the polarizing film 12 has polarization characteristics in the direction shown by B in FIG.

は厚い偏光板などが使用される。 As shown in FIG. 3, the windshield 11 is made of laminated glass in which a pair of glass plates 16, 16 are bonded together with a polyvinyl tyral interlayer film 17 interposed therebetween, and the polarizing film 12 is made of a pair of glass plates 1
6 and 16 together with a polyvinyl tyral intermediate film 17. The polarizing plate 13 may be a transparent plastic or glass plate with a polarizing film attached to it, a polarizing film sandwiched between a pair of plastic or glass plates, or a thick polarizing plate.
上記の構成において、偏光板１３をピポツト１
４を中心に下方に回動させると、ドライバーＤか

空間が狭められた印象をドライバーＤに与えるこ
とはない。そして、偏光板１３をピポツト１４を
中心に上方に回動させると、ドライバーＤから見
て偏光フイルム１２と偏光板１３とが重ならない
状態となるので、偏光フイルム１２を透過した外
光はそのまま車内に入射する。 In the above configuration, the polarizing plate 13 is
4, the polarizing film 12 and the polarizing plate 13 will be in an overlapping state when viewed from the driver D. Therefore, external light such as sunlight that has passed through the polarizing film 12 cannot pass through the polarizing plate 13 and is blocked, thereby preventing the driver D from being dazzled. In addition, in this state, the polarizing plate 13
Since the interior space of the vehicle can be freely viewed through the vehicle, driver D does not get the impression that the interior space of the vehicle is constricted. Then, when the polarizing plate 13 is rotated upward around the pivot 14, the polarizing film 12 and the polarizing plate 13 do not overlap when viewed from the driver D, so the external light that has passed through the polarizing film 12 is directly directed into the vehicle. incident on .
なお、この実施例では、第２図中ＡおよびＢに
示すように、偏光フイルム１２と偏光板１３との
偏光方向が直交しているので、偏光フイルム１２
と偏光板１３とが重なつた状態では外光がほとん
ど遮断されるが、偏光フイルム１２と偏光板１３
との偏光方向がなす角度を直角よりも小さくすれ

を調整することができる。 In this embodiment, as shown in A and B in FIG. 2, since the polarization directions of the polarizing film 12 and the polarizing plate 13 are orthogonal,
When the polarizing film 12 and the polarizing plate 13 overlap, most of the external light is blocked, but the polarizing film 12 and the polarizing plate 13
By making the angle between the polarization direction and the polarization direction smaller than a right angle, it is possible to adjust the degree of light shielding by allowing some of the external light to pass through.
また、偏光フイルム１２は第４図に示すように

る。 Further, the polarizing film 12 may be attached to the indoor side of the windshield 11 as shown in FIG. 4. Alternatively, as shown in FIG. 5, if the windshield 11 is made of double-glazed glass made by joining a pair of glass plates 18, 18 with a spacer 19 interposed therebetween, the polarizing film 12 may be attached to the inside of one of the glass plates 18. You may also do so. It is preferable that the windshield 11 is made of a raw plate; if tempered glass is used, the polarizing film 12 causes the stress pattern to become visible.

ることもない。"Effects of the invention" As explained above, according to the invention, a polarizing film is provided on at least a part of the glass window of a car, and a polarizing plate can be layered on the inside of the car in a cross nicol state with this polarizing film. Once installed, the polarizing film on the glass window and the polarizing plate on the inside of the car are layered to block sunlight and other external light.
Alternatively, external light can be freely transmitted by not overlapping the two layers. Further, by changing the polarization characteristics of the polarizing film and the polarizing plate, it is possible to block all or part of the external light. Furthermore, when the polarizing film and the polarizing plate are layered, the polarizing plate does not block the view inside the car, so the space inside the car does not give the impression of being narrowed.
