　図１に示すように、ドアガラス２の昇降をガイドするサッシュの無いドア、いわゆるサッシュレスドア１が採用されることがある。サッシュレスドア１は、車両側面の乗降口を開閉する。 As shown in FIG. 1, a door without a sash that guides the raising and lowering of the door glass 2, a so-called sashless door 1, may be adopted. The sashless door 1 opens and closes the entrance on the side of the vehicle.
　サッシュレスドア１は、不図示の２つのパネルを有し、これらのパネルの間にドアガラス２が配置される。ドアガラス２は、図１に一点鎖線で示す全開位置にて、サッシュレスドア１を構成する２つのパネルの間に収容される。 The sashless door 1 has two panels (not shown), and the door glass 2 is arranged between these panels. The door glass 2 is housed between the two panels constituting the sashless door 1 at the fully open position shown by the alternate long and short dash line in FIG.
　ドアガラス２は、図１に一点鎖線で示す全開位置と、図１に実線で示す全閉位置との間で昇降させられ、車両側面の窓を開閉する。ドアガラス２は、図１に矢印で示すように斜めに昇降させられてもよい。サッシュレスドア１に昇降自在に取付けられるドアガラス２を、サッシュレスドアガラスと呼ぶ。 The door glass 2 is moved up and down between the fully open position shown by the alternate long and short dash line in FIG. 1 and the fully closed position shown by the solid line in FIG. 1 to open and close the window on the side surface of the vehicle. The door glass 2 may be moved up and down diagonally as shown by an arrow in FIG. The door glass 2 that can be moved up and down to the sashless door 1 is called a sashless door glass.
　ドアガラス２は、ガラス板３を有する。ガラス板３は、サッシュレスドア１に対して昇降自在に取付けられる。ガラス板３の厚みは、耐傷性の観点から、例えば１．８ｍｍ以上である。また、ガラス板３の厚みは、軽量性及び成形性の観点から、６．０ｍｍ以下である。 The door glass 2 has a glass plate 3. The glass plate 3 is vertically attached to the sashless door 1. The thickness of the glass plate 3 is, for example, 1.8 mm or more from the viewpoint of scratch resistance. The thickness of the glass plate 3 is 6.0 mm or less from the viewpoint of light weight and moldability.
　ガラス板３は、無機ガラス及び有機ガラスのいずれでもよい。無機ガラスとしては、例えばソーダライムガラス、アルミノシリケートガラス等が挙げられる。また、無機ガラスは、未強化ガラス、強化ガラスのいずれでもよい。未強化ガラスは、溶融ガラスを板状に成形し、徐冷したものである。強化ガラスは、未強化ガラスの表面に圧縮応力層を形成したものである。強化ガラスは、物理強化ガラス（例えば風冷強化ガラス）、化学強化ガラスのいずれでもよい。一方、有機ガラスとしては、ポリカーボネート、アクリル樹脂、ポリ塩化ビニル、ポリスチレン等の透明樹脂が挙げられる。アクリル樹脂は、例えばポリメチルメタクリレートである。 The glass plate 3 may be either inorganic glass or organic glass. Examples of the inorganic glass include soda lime glass and aluminosilicate glass. Further, the inorganic glass may be either untempered glass or tempered glass. Untempered glass is made by molding molten glass into a plate shape and slowly cooling it. Tempered glass is formed by forming a compressive stress layer on the surface of untempered glass. The tempered glass may be either physically tempered glass (for example, wind-cooled tempered glass) or chemically tempered glass. On the other hand, examples of the organic glass include transparent resins such as polycarbonate, acrylic resin, polyvinyl chloride, and polystyrene. The acrylic resin is, for example, polymethylmethacrylate.
　ガラス板３は、車外側に凸の湾曲形状を有する。ガラス板３の曲げ成形としては、重力成形、またはプレス成形等が用いられる。ガラス板３が物理強化ガラスである場合は、曲げ成形において均一に加熱したガラス板を軟化点付近の温度から急冷し、ガラス表面とガラス内部との温度差によってガラス表面に圧縮応力を生じさせることで、ガラス表面を強化してもよい。ガラス板３が化学強化ガラスである場合は、曲げ成形の後、イオン交換法等によってガラス表面に圧縮応力を生じさせることでガラス表面を強化してもよい。 The glass plate 3 has a curved shape that is convex on the outside of the vehicle. As the bending molding of the glass plate 3, gravity molding, press molding or the like is used. When the glass plate 3 is physically tempered glass, the glass plate uniformly heated in bending molding is rapidly cooled from a temperature near the softening point, and a compressive stress is generated on the glass surface due to the temperature difference between the glass surface and the inside of the glass. Then, the glass surface may be strengthened. When the glass plate 3 is chemically tempered glass, the glass surface may be strengthened by generating compressive stress on the glass surface by an ion exchange method or the like after bending molding.

The front side 33 and the rear side 34 of the may be inclined. For example, the front side 33 and the rear side 34 are parallel to the elevating direction of the door glass 2, and are inclined rearward toward the upper side.

The functional film 4 limits the transmission of ultraviolet rays, for example. The functional film 4 may further limit the transmission of infrared rays. The functional film 4 may be any of an ultraviolet cut film, an infrared cut film, an antifogging film, an antifouling film, a low antireflection film, and an electromagnetic shielding film. Further, the functional film 4 may be colored and transparent, or may be an antiglare film that lowers the transmittance of visible light.
　機能膜４は、ガラス板３の車内面３１に形成される。機能膜４がガラス板３の車内面３１に形成される場合、機能膜４がガラス板３の車外面に形成される場合に比べて、雨水及び砂埃等による機能膜４の劣化を抑制できる。 The functional film 4 is formed on the vehicle inner surface 31 of the glass plate 3. When the functional film 4 is formed on the vehicle inner surface 31 of the glass plate 3, deterioration of the functional film 4 due to rainwater, dust, etc. can be suppressed as compared with the case where the functional film 4 is formed on the vehicle outer surface of the glass plate 3.
　機能膜４は、図１に示すように、ガラス板３の車内面３１の周縁３２よりも内側に、前辺４３と、後辺４４と、前辺４３の上端と後辺４４の上端とを結ぶ上辺４５と、を含む。ガラス板３の車内面３１の周縁３２が露出しており、その露出部分がシール部材５（図２参照）に押し当てられる。 As shown in FIG. 1, the functional film 4 has a front side 43, a rear side 44, and an upper end of the front side 43 and an upper end of the rear side 44 inside the peripheral edge 32 of the vehicle inner surface 31 of the glass plate 3. Includes the upper side 45 to be connected. The peripheral edge 32 of the vehicle inner surface 31 of the glass plate 3 is exposed, and the exposed portion is pressed against the seal member 5 (see FIG. 2).
　シール部材５は、車両側面の乗降口の開口縁に設けられ、その開口縁とドアガラス２との隙間を塞ぎ、雨水及び砂埃等が車内に入り込むのを防止する。シール部材５は、ガラス板３の車内面３１の周縁３２のうち少なくとも前辺３３と後辺３４と上辺３５とに接触し、少なくとも前方、後方及び上方から雨水等が車内に入り込むのを防止する。 The seal member 5 is provided at the opening edge of the entrance / exit on the side surface of the vehicle, closes the gap between the opening edge and the door glass 2, and prevents rainwater, dust, etc. from entering the vehicle. The sealing member 5 contacts at least the front side 33, the rear side 34, and the upper side 35 of the peripheral edge 32 of the vehicle inner surface 31 of the glass plate 3 to prevent rainwater or the like from entering the vehicle from at least the front, the rear, and the upper side. ..
　図１に示すように、機能膜４の前辺４３はガラス板３の前辺３３に沿って形成され、機能膜４の後辺４４はガラス板３の後辺３４に沿って形成される。ガラス板３の前辺３３及び後辺３４が傾斜する場合、機能膜４の前辺４３と後辺４４も傾斜する。また、機能膜４の上辺４５は、ガラス板３の上辺３５に沿って形成される。 As shown in FIG. 1, the front side 43 of the functional film 4 is formed along the front side 33 of the glass plate 3, and the rear side 44 of the functional film 4 is formed along the rear side 34 of the glass plate 3. When the front side 33 and the rear side 34 of the glass plate 3 are inclined, the front side 43 and the rear side 44 of the functional film 4 are also inclined. Further, the upper side 45 of the functional film 4 is formed along the upper side 35 of the glass plate 3.
　サッシュレスドア１が閉じられると、図２に示すように、ガラス板３の車内面３１がシール部材５に押し当てられる。この状態で、ガラス板３の車内面３１とシール部材５との間にくさび状の隙間Ｇが形成される。隙間Ｇは、ガラス板３の車内面３１の周縁３２（図２では後辺３４）とは反対側（図２ではＸ軸正方向）に開口する。 When the sashless door 1 is closed, the vehicle inner surface 31 of the glass plate 3 is pressed against the seal member 5 as shown in FIG. In this state, a wedge-shaped gap G is formed between the vehicle inner surface 31 of the glass plate 3 and the sealing member 5. The gap G opens on the side opposite to the peripheral edge 32 (rear side 34 in FIG. 2) of the vehicle inner surface 31 of the glass plate 3 (in the positive direction of the X axis in FIG. 2).
　隙間Ｇには、ガラス板３の昇降中に、機能膜４とシール部材５とが接触しないように、機能膜４の前辺４３と後辺４４の少なくとも一部（図２では後辺４４）が配置される。その結果、機能膜４の摩耗を抑制でき、且つ機能膜４の周縁を車両の搭乗者Ｈから隠蔽できる。 In the gap G, at least a part of the front side 43 and the rear side 44 of the functional film 4 (the rear side 44 in FIG. 2) so that the functional film 4 and the sealing member 5 do not come into contact with each other while the glass plate 3 is raised and lowered. Is placed. As a result, wear of the functional film 4 can be suppressed, and the peripheral edge of the functional film 4 can be concealed from the occupant H of the vehicle.
　図３に強調して示すように、機能膜４の前辺４３と後辺４４の少なくとも一部（図３では後辺４４）は、波線であってもよい。波線は、基準線Ｌの前にはみ出すことと、基準線Ｌの後にはみ出すこととを繰り返す曲線である。 As emphasized in FIG. 3, at least a part of the front side 43 and the rear side 44 of the functional film 4 (the rear side 44 in FIG. 3) may be wavy lines. The wavy line is a curve that repeats protruding before the reference line L and protruding after the reference line L.
　機能膜４の後辺４４の基準線Ｌは、ガラス板３の車内面３１の後辺３４に平行に設定され、基準線Ｌの前にはみ出す部分の合計面積と、基準線Ｌの後にはみ出す部分の合計面積とが等しくなるように設定される。 The reference line L of the rear side 44 of the functional film 4 is set parallel to the rear side 34 of the vehicle inner surface 31 of the glass plate 3, and the total area of the portion protruding in front of the reference line L and the portion protruding after the reference line L. Is set to be equal to the total area of.
　同様に、機能膜４の前辺４３の基準線Ｌは、ガラス板３の前辺３３に平行に設定され、基準線Ｌの前にはみ出す部分の合計面積と、基準線Ｌの後にはみ出す部分の合計面積とが等しくなるように設定される。 Similarly, the reference line L of the front side 43 of the functional film 4 is set parallel to the front side 33 of the glass plate 3, and the total area of the portion protruding in front of the reference line L and the portion protruding after the reference line L. It is set to be equal to the total area.
　波線の振幅Ａの平均値（平均振幅）は、例えば０．３ｍｍ～８ｍｍ、好ましくは０．３ｍｍ～５ｍｍである。また、波線の周期Ｐの平均値（平均周期）は、例えば１０ｍｍ～３００ｍｍ、好ましくは２０ｍｍ～２００ｍｍである。 The average value (average amplitude) of the wavy line amplitude A is, for example, 0.3 mm to 8 mm, preferably 0.3 mm to 5 mm. The average value (average period) of the wavy line period P is, for example, 10 mm to 300 mm, preferably 20 mm to 200 mm.
　機能膜４の前辺４３と後辺４４の少なくとも一部が波線であれば、波線によって光が乱反射されるので、前辺４３又は後辺４４を車両の外部から目立たないようにすることができる。図１０（Ａ）に直線状の前辺４３Ａを車外側から撮像した画像の一例を示し、図１０（Ｂ）に波線状の前辺４３Ｂを車外側から撮像した画像の一例を示す。また、図１１（Ａ）に直線状の前辺４３Ａを車内側から撮像した画像の一例を示し、図１１（Ｂ）に波線状の前辺４３Ｂを車内側から撮像した画像の一例を示す。図１０（Ｂ）及び図１１（Ｂ）に示す波線状の前辺４３Ｂは、振幅Ａが２ｍｍであり、周期Ｐが６０ｍｍであった。 If at least a part of the front side 43 and the rear side 44 of the functional film 4 is a wavy line, the light is diffusely reflected by the wavy line, so that the front side 43 or the rear side 44 can be made inconspicuous from the outside of the vehicle. .. FIG. 10A shows an example of an image of the linear front side 43A captured from the outside of the vehicle, and FIG. 10B shows an example of an image of the wavy front side 43B captured from the outside of the vehicle. Further, FIG. 11A shows an example of an image of the linear front side 43A captured from the inside of the vehicle, and FIG. 11B shows an example of an image of the wavy front side 43B captured from the inside of the vehicle.

　図１０（Ａ）及び図１０（Ｂ）に示す画像は、ドアガラス２の車内側に２本の棒状の蛍光灯ＦＬ１、ＦＬ２を配置し、ドアガラス２の車外側にカメラを配置して撮像した。ドアガラス２と蛍光灯ＦＬ１、ＦＬ２の間隔は１ｍであった。また、ドアガラス２とカメラの間隔は５０ｃｍであった。機能膜４の前辺４３Ａ、４３Ｂと蛍光灯ＦＬ１、ＦＬ２は、平行に配置した。図１０（Ａ）と図１０（Ｂ）を比較すれば明らかなように、直線状の前辺４３Ａに比べて、波線状の前辺４３Ｂは、ドアガラス２を透過する光の乱反射を抑制でき、目立たたないようにできることが分かる。 The images shown in FIGS. 10A and 10B are captured by arranging two rod-shaped fluorescent lamps FL1 and FL2 inside the door glass 2 and arranging a camera on the outside of the door glass 2. bottom. The distance between the door glass 2 and the fluorescent lamps FL1 and FL2 was 1 m. The distance between the door glass 2 and the camera was 50 cm. The front sides 43A and 43B of the functional film 4 and the fluorescent lamps FL1 and FL2 were arranged in parallel. As is clear from comparing FIGS. 10 (A) and 10 (B), the wavy front side 43B can suppress diffused reflection of light transmitted through the door glass 2 as compared with the linear front side 43A. You can see that it can be made inconspicuous.
　また、図１１（Ａ）及び図１１（Ｂ）に示す画像は、ドアガラス２の車外側に２本の棒状の蛍光灯ＦＬ１、ＦＬ２を配置し、ドアガラス２の車内側にカメラを配置して撮像した。ドアガラス２と蛍光灯ＦＬ１、ＦＬ２の間隔は１ｍであった。また、ドアガラス２とカメラの間隔は５０ｃｍであった。機能膜４の前辺４３Ａ、４３Ｂと蛍光灯ＦＬ１、ＦＬ２は、平行に配置した。図１１（Ａ）と図１１（Ｂ）を比較すれば明らかなように、直線状の前辺４３Ａに比べて、波線状の前辺４３Ｂは、ドアガラス２を透過する光の乱反射を抑制でき、目立たたないようにできることが分かる。 Further, in the images shown in FIGS. 11A and 11B, two rod-shaped fluorescent lamps FL1 and FL2 are arranged on the outside of the door glass 2 and a camera is arranged on the inside of the door glass 2. I took an image. The distance between the door glass 2 and the fluorescent lamps FL1 and FL2 was 1 m. The distance between the door glass 2 and the camera was 50 cm. The front sides 43A and 43B of the functional film 4 and the fluorescent lamps FL1 and FL2 were arranged in parallel. As is clear from comparing FIGS. 11A and 11B, the wavy front side 43B can suppress diffused reflection of light transmitted through the door glass 2 as compared with the linear front side 43A. You can see that it can be made inconspicuous.
　機能膜４の上辺４５での先端角αは、機能膜４の前辺４３での先端角βと機能膜４の後辺４４での先端角γの両方に比べて小さい。つまり、機能膜４の上辺４５の先端は、機能膜４の前辺４３の先端と機能膜４の後辺４４の先端の両方に比べて尖っている。α、β、γは、機能膜４の周縁における、機能膜４の車外側の面と車内側の面のなす角である。α、β、γの測定方法は、後述する。 The tip angle α on the upper side 45 of the functional film 4 is smaller than both the tip angle β on the front side 43 of the functional film 4 and the tip angle γ on the rear side 44 of the functional film 4. That is, the tip of the upper side 45 of the functional film 4 is sharper than both the tip of the front side 43 of the functional film 4 and the tip of the rear side 44 of the functional film 4. α, β, and γ are angles formed by the outer surface of the functional film 4 and the inner surface of the vehicle on the peripheral edge of the functional film 4. The method for measuring α, β, and γ will be described later.
　ドアガラス２が図１に一点鎖線で示す全開位置から上昇させられる際に、機能膜４の上辺４５が不図示のベルトモールに接触する。ベルトモールは、サッシュレスドア１の上縁に設けられ、サッシュレスドア１を構成する２つのパネルの隙間に雨水等が入り込むのを制限する。 When the door glass 2 is raised from the fully open position shown by the alternate long and short dash line in FIG. 1, the upper side 45 of the functional film 4 comes into contact with a belt molding (not shown). The belt molding is provided on the upper edge of the sashless door 1 and restricts rainwater or the like from entering the gap between the two panels constituting the sashless door 1.
　本実施形態によれば、機能膜４の上辺４５の先端が尖っているので、機能膜４の上辺４５の先端が尖っていない場合、例えばガラス板３の車内面３１に対して垂直な段差である場合に比べて、ドアガラス２の上昇時に機能膜４とベルトモールとの摩擦抵抗を低減できる。従って、機能膜４の摩耗を抑制できる。 According to the present embodiment, since the tip of the upper side 45 of the functional film 4 is sharp, when the tip of the upper side 45 of the functional film 4 is not sharp, for example, at a step perpendicular to the vehicle inner surface 31 of the glass plate 3. Compared with a certain case, the frictional resistance between the functional film 4 and the belt molding can be reduced when the door glass 2 is raised. Therefore, wear of the functional film 4 can be suppressed.
　機能膜４の上辺４５での先端角αは、例えば０．０４ｍｒａｄ～０．３ｍｒａｄ、好ましくは０．０４ｍｒａｄ～０．２ｍｒａｄである。先端角αは、図４に示す３つの測定点ＳＰ１～ＳＰ３で測定された先端角α１～α３の平均値である。３つの測定点ＳＰ１～ＳＰ３は、上辺４５を４等分するように、上辺４５の一端４５ａと他端４５ｂの途中に設定される。 The tip angle α on the upper side 45 of the functional film 4 is, for example, 0.04 mrad to 0.3 mrad, preferably 0.04 mrad to 0.2 mrad.

　先端角α１～α３は、それぞれ、上辺４５に直交する断面にて測定され、機能膜４の膜厚分布から測定される。機能膜４の膜厚分布は、例えば白色干渉顕微鏡によって測定される。先端角α１～α３の測定方法は同じなので、以下、代表的に先端角α１の測定方法について説明する。先端角α１は、図５に示すように、測定点ＳＰ１と下記点Ｐ１とを結ぶ直線Ｌ１と、ガラス板３の車内面３１とのなす角である。 The tip angles α1 to α3 are each measured in a cross section orthogonal to the upper side 45, and are measured from the film thickness distribution of the functional film 4. The film thickness distribution of the functional film 4 is measured by, for example, a white interference microscope. Since the measuring methods of the tip angles α1 to α3 are the same, the measuring method of the tip angles α1 will be described below as a representative. As shown in FIG. 5, the tip angle α1 is an angle formed by a straight line L1 connecting the measurement point SP1 and the following point P1 and the vehicle inner surface 31 of the glass plate 3.

The tip angle β is an average value of the tip angles β1 to β3 measured at the three measurement points SP4 to SP6 shown in FIG. The three measurement points SP4 to SP6 are set in the middle of one end 43a and the other end 43b of the front side 43 so as to divide the front side 43 into four equal parts.
　先端角β１～β３は、それぞれ、前辺４３に直交する断面にて測定され、機能膜４の膜厚分布から測定される。機能膜４の膜厚分布は、例えば白色干渉顕微鏡によって測定される。先端角β１～β３の測定方法は同じなので、以下、代表的に先端角β１の測定方法について説明する。先端角β１は、図６に示すように、測定点ＳＰ４と下記点Ｐ２とを結ぶ直線Ｌ２と、ガラス板３の車内面３１とのなす角である。 The tip angles β1 to β3 are each measured in a cross section orthogonal to the front side 43, and are measured from the film thickness distribution of the functional film 4. The film thickness distribution of the functional film 4 is measured by, for example, a white interference microscope. Since the methods for measuring the tip angles β1 to β3 are the same, the method for measuring the tip angles β1 will be typically described below. As shown in FIG. 6, the tip angle β1 is an angle formed by a straight line L2 connecting the measurement point SP4 and the following point P2 and the vehicle inner surface 31 of the glass plate 3.
　点Ｐ２は、機能膜４の車内側の面に設定され、紫外線（波長３５５ｎｍ）の透過率が１．０％である点と、赤外線（波長８７５ｎｍ）の透過率が３０％である点とのうち、前辺４３に近い方の点である。紫外線の透過率の測定方法と、赤外線の透過率の測定方法とは、それぞれ、上記の通りである。点Ｐ２での機能膜４の膜厚は、例えば２μｍである。 Point P2 is set on the inner surface of the functional film 4 and has a transmittance of ultraviolet rays (wavelength 355 nm) of 1.0% and a transmittance of infrared rays (wavelength 875 nm) of 30%. Of these, the point closer to the front side 43.

The film thickness of the functional film 4 at the point P2 is, for example, 2 μm.
　また、機能膜４の後辺４４での先端角γは、例えば０．６ｍｒａｄ～１．０ｍｒａｄ、好ましくは０．７ｍｒａｄ～０．９ｍｒａｄである。先端角γは、図４に示す３つの測定点ＳＰ７～ＳＰ９で測定された先端角γ１～γ３の平均値である。３つの測定点ＳＰ７～ＳＰ９は、後辺４４を４等分するように、後辺４４の一端４４ａと他端４４ｂの途中に設定される。 The tip angle γ on the rear side 44 of the functional film 4 is, for example, 0.6 mrad to 1.0 mrad, preferably 0.7 mrad to 0.9 mrad. The tip angle γ is an average value of the tip angles γ1 to γ3 measured at the three measurement points SP7 to SP9 shown in FIG. The three measurement points SP7 to SP9 are set in the middle of one end 44a and the other end 44b of the rear side 44 so as to divide the rear side 44 into four equal parts.
　先端角γ１～γ３は、それぞれ、後辺４４に直交する断面にて測定され、機能膜４の膜厚分布から測定される。機能膜４の膜厚分布は、例えば白色干渉顕微鏡によって測定される。先端角γ１～γ３の測定方法は同じなので、以下、代表的に先端角γ１の測定方法について説明する。先端角γ１は、図７に示すように、測定点ＳＰ７と下記点Ｐ３とを結ぶ直線Ｌ３と、ガラス板３の車内面３１とのなす角である。 The tip angles γ1 to γ3 are each measured in a cross section orthogonal to the rear side 44, and are measured from the film thickness distribution of the functional film 4. The film thickness distribution of the functional film 4 is measured by, for example, a white interference microscope. Since the methods for measuring the tip angles γ1 to γ3 are the same, the method for measuring the tip angles γ1 will be typically described below. As shown in FIG. 7, the tip angle γ1 is an angle formed by a straight line L3 connecting the measurement point SP7 and the following point P3 and the vehicle inner surface 31 of the glass plate 3.
　点Ｐ３は、機能膜４の車内側の面に設定され、紫外線（波長３５５ｎｍ）の透過率が１．０％である点と、赤外線（波長８７５ｎｍ）の透過率が３０％である点とのうち、後辺４４に近い方の点である。紫外線の透過率の測定方法と、赤外線の透過率の測定方法とは、それぞれ、上記の通りである。点Ｐ３での機能膜４の膜厚は、例えば２μｍである。 The point P3 is set on the inner surface of the functional film 4 and has a transmittance of ultraviolet rays (wavelength 355 nm) of 1.0% and a transmittance of infrared rays (wavelength 875 nm) of 30%. Of these, the point closer to the rear side 44.

　次に、図８を参照して、ドアガラス２の製造方法について説明する。ドアガラス２の製造方法は、ガラス板３の車内面３１にコーティング液ＣＬを塗布し、機能膜４を形成することを有する。コーティング液ＣＬの塗布には、例えばフローコート法が用いられる。 Next, a method of manufacturing the door glass 2 will be described with reference to FIG. The method for manufacturing the door glass 2 includes applying the coating liquid CL to the vehicle inner surface 31 of the glass plate 3 to form the functional film 4. For example, the flow coating method is used for applying the coating liquid CL.
　フローコート法では、ガラス板３を立てた状態で、ガラス板３の車内面３１にコーティング液ＣＬをかけ流す。コーティング液ＣＬは、ノズル６から、ガラス板３の車内面３１の目標地点ＴＰに向けて吐出され、目標地点ＴＰから重力によって下方にかけ流される。 In the flow coat method, the coating liquid CL is poured on the vehicle inner surface 31 of the glass plate 3 with the glass plate 3 upright. The coating liquid CL is discharged from the nozzle 6 toward the target point TP on the vehicle inner surface 31 of the glass plate 3, and is flowed downward by gravity from the target point TP.
　ノズル６は、ガラス板３の車内面３１の上辺に沿って移動させられる。その結果、コーティング液ＣＬの目標地点ＴＰも、図９に示すようにガラス板３の車内面３１の上辺３５に沿って移動させられる。これにより、所望の領域に機能膜４が形成される。 The nozzle 6 is moved along the upper side of the vehicle inner surface 31 of the glass plate 3. As a result, the target point TP of the coating liquid CL is also moved along the upper side 35 of the vehicle inner surface 31 of the glass plate 3 as shown in FIG. As a result, the functional film 4 is formed in a desired region.
　機能膜４は、ガラス板３の車内面３１の周縁３２のうち、前辺３３と後辺３４と上辺３５とから離して形成される。従って、コーティング液ＣＬの目標地点ＴＰも、ガラス板３の車内面３１の周縁３２のうち、前辺３３と後辺３４と上辺３５とから離して移動させられる。目標地点ＴＰの移動方向は図９に矢印で示す方向とは逆でもよく、目標地点ＴＰの出発地点と終了地点とは逆でもよい。 The functional film 4 is formed apart from the front side 33, the rear side 34, and the upper side 35 of the peripheral edge 32 of the vehicle inner surface 31 of the glass plate 3. Therefore, the target point TP of the coating liquid CL is also moved away from the front side 33, the rear side 34, and the upper side 35 of the peripheral edge 32 of the vehicle inner surface 31 of the glass plate 3. The moving direction of the target point TP may be opposite to the direction indicated by the arrow in FIG. 9, and may be opposite to the start point and end point of the target point TP.
　なお、本実施形態では、コーティング液ＣＬの目標地点を移動させるべく、ノズル６を移動させるが、ガラス板３を移動させてもよく、ノズル６とガラス板３の両方を移動させてもよい。 In the present embodiment, the nozzle 6 is moved in order to move the target point of the coating liquid CL, but the glass plate 3 may be moved, or both the nozzle 6 and the glass plate 3 may be moved.
　コーティング液ＣＬの吐出方向（図８に示す矢印Ｂ方向）から見て、図９に実線で示すように、ガラス板３の前辺３３又は後辺３４が鉛直に配置された状態で、コーティング液ＣＬがかけ流される。 As shown by the solid line in FIG. 9, when viewed from the discharge direction of the coating liquid CL (direction of arrow B shown in FIG. 8), the coating liquid is in a state where the front side 33 or the rear side 34 of the glass plate 3 is vertically arranged. CL is flushed.
　なお、車両搭載時には、図９に二点鎖線で示すように、ガラス板３の前辺３３又は後辺３４は傾斜して配置される。車両搭載時とは異なる向きのガラス板３の車内面３１に対して、コーティング液ＣＬがかけ流される。 When mounted on a vehicle, the front side 33 or the rear side 34 of the glass plate 3 is arranged so as to be inclined as shown by the alternate long and short dash line in FIG. The coating liquid CL is poured onto the vehicle inner surface 31 of the glass plate 3 in a direction different from that when mounted on the vehicle.
　本実施形態によれば、上記の通り、コーティング液ＣＬの吐出方向から見て、ガラス板３の前辺３３が鉛直に配置された状態で、前辺３３に沿ってコーティング液ＣＬがかけ流される。その結果、機能膜４の前辺４３が、ガラス板３の前辺３３に沿って形成される。 According to the present embodiment, as described above, the coating liquid CL is poured along the front side 33 in a state where the front side 33 of the glass plate 3 is vertically arranged when viewed from the discharge direction of the coating liquid CL. .. As a result, the front side 43 of the functional film 4 is formed along the front side 33 of the glass plate 3.
　また、本実施形態によれば、上記の通り、コーティング液ＣＬの吐出方向から見て、ガラス板３の車内面３１の後辺３４が鉛直に配置された状態で、後辺３４に沿ってコーティング液ＣＬがかけ流される。その結果、機能膜４の後辺４４が、ガラス板３の後辺３４に沿って形成される。 Further, according to the present embodiment, as described above, the rear side 34 of the vehicle inner surface 31 of the glass plate 3 is vertically arranged and coated along the rear side 34 when viewed from the discharge direction of the coating liquid CL. The liquid CL is poured. As a result, the rear side 44 of the functional film 4 is formed along the rear side 34 of the glass plate 3.
　コーティング液ＣＬがかけ流される際に、流れが乱れ、機能膜４の前辺４３と後辺４４の少なくとも一部が波線になる。波線の振幅Ａの平均値、及び波線の周期Ｐの平均値は、コーティング液ＣＬの吐出流量等で決まる。 When the coating liquid CL is poured, the flow is disturbed, and at least a part of the front side 43 and the rear side 44 of the functional film 4 becomes wavy lines. The average value of the wavy line amplitude A and the average value of the wavy line period P are determined by the discharge flow rate of the coating liquid CL and the like.
　コーティング液ＣＬがかけ流される際に、コーティング液ＣＬは重力によって下方に引き伸ばされる。それゆえ、機能膜４の上辺４５での先端角αは、機能膜４の前辺４３での先端角βと機能膜４の後辺４４での先端角γの両方に比べて小さくなる。 When the coating liquid CL is poured, the coating liquid CL is stretched downward by gravity. Therefore, the tip angle α on the upper side 45 of the functional film 4 is smaller than both the tip angle β on the front side 43 of the functional film 4 and the tip angle γ on the rear side 44 of the functional film 4.
　以上、本開示に係るサッシュレスドアガラスとその製造方法について説明したが、本開示は上記実施形態等に限定されない。特許請求の範囲に記載された範疇内において、各種の変更、修正、置換、付加、削除、及び組み合わせが可能である。それらについても当然に本開示の技術的範囲に属する。 Although the sashless door glass and the manufacturing method thereof according to the present disclosure have been described above, the present disclosure is not limited to the above-described embodiment and the like. Within the scope of the claims, various changes, modifications, replacements, additions, deletions, and combinations are possible. Of course, they also belong to the technical scope of the present disclosure.
