[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2016-88430 Summary of the Invention [Problem to be solved by the invention]

[0004] Vehicle window glass used in sashless doors does not have a sash (window frame) to support the window glass, so there is a problem that the support rigidity of the window glass is lower than in doors with a sash. In particular, when the window glass is raised or lowered, the window glass cannot be guided by the sash, so the rigidity of the window glass itself needs to be increased.

[0005] The present disclosure has been made in view of the above points, and has an object to provide a vehicle window glass and a sashless door that can increase the rigidity of the window glass. [Means for solving the problem]

[0006] A vehicle window glass according to one aspect of the present disclosure is a vehicle window glass used in a sashless door. The vehicle window glass is laminated glass including a first glass plate, a second glass plate, and an interlayer film sandwiched between the first glass plate and the second glass plate, and a reinforcing member is provided on at least one of a front side edge and a rear side edge of the vehicle of the vehicle window glass, and the reinforcing member is disposed between the first glass plate and the second glass plate in a thickness direction of the vehicle window glass.

[0007] A sashless door according to one aspect of the present disclosure includes the vehicle window glass described above and a door panel to which the vehicle window glass is attached. [Effects of the Invention]

[0008] According to the present disclosure, it is possible to provide a vehicle window glass and a sashless door that can increase the rigidity of the window glass. [Brief explanation of the drawings]

[Figure 7] 1 is a plan view showing a configuration example of a sashless door according to an embodiment. FIG. DETAILED DESCRIPTION OF THE INVENTION

[0010] The present disclosure will now be described with reference to the drawings. Fig. 1 is a plan view showing an example of the configuration of a vehicle window glass according to an embodiment, as seen from the vehicle exterior. Fig. 2 is a cross-sectional view showing the example of the configuration of a vehicle window glass according to an embodiment, taken along the cutting line II-II in Fig. 1. The vehicle window glass 1 according to this embodiment is a vehicle window glass used in a sashless door.

[0011] As shown in Fig. 1, a vehicle window glass 1 according to this embodiment is provided with holders 50_1 and 50_2 that hold the vehicle window glass 1 on the underside of the vehicle window glass 1. In this embodiment, the vehicle window glass 1 is held by the holders 50_1 and 50_2, and these holders 50_1 and 50_2 are fixed to a lifting device (not shown). The vehicle window glass 1 moves up and down by the driving force of the lifting device (not shown).

[0012] The vehicle window glass 1 according to this embodiment is constructed using laminated glass. Specifically, as shown in Fig. 2, the vehicle window glass 1 includes a first glass sheet 11, a second glass sheet 12, and an interlayer film 13 sandwiched between the first glass sheet 11 and the second glass sheet 12. The first glass sheet 11 and the second glass sheet 12 are bonded to each other using the interlayer film 13. For example, the first glass sheet 11 is disposed on the exterior side of the vehicle, and the second glass sheet 12 is disposed on the interior side of the vehicle.

[0013] The thickness of the vehicle window glass 1 is preferably 2.8 mm to 10 mm, and more preferably 3.0 mm to 8.0 mm. When the thickness of the vehicle window glass 1 is 2.8 mm to 10 mm, sufficient transmittance as a vehicle window glass can be ensured, and sufficient strength can also be ensured.

[0014] The first glass plate 11 and the second glass plate 12 are made of inorganic glass. Examples of inorganic glass include soda lime glass and aluminosilicate glass. The inorganic glass may be either untempered glass or tempered glass. Untempered glass is made by forming molten glass into a plate shape and slowly cooling it. Tempered glass is made by forming a compressive stress layer on the surface of untempered glass. Tempered glass may be either physically tempered glass (for example, air-cooled tempered glass) or chemically tempered glass.

[0015] Although not shown, the first glass sheet 11 and the second glass sheet 12 are formed to have a convex shape facing the exterior of the vehicle. Gravity forming, press forming, or the like is used to bend the glass sheets. The glass surface may be physically strengthened by rapidly cooling the uniformly heated glass sheet from a temperature near its softening point during bending, thereby generating compressive stress on the glass surface due to the temperature difference between the glass surface and the interior of the glass. After bending, the glass surface may be chemically strengthened by generating compressive stress on the glass surface using an ion exchange method or the like.

[0016] The thickness of the first glass plate 11 is preferably 1.1 mm to 5.0 mm, more preferably 1.1 mm to 4.2 mm, and even more preferably 1.1 mm to 3.6 mm, and may be 1.8 mm to 3.0 mm. When the thickness of the first glass plate 11 is 1.1 mm to 4.2 mm, the weight of the vehicle window glass can be reduced and sufficient strength can be ensured. Furthermore, the thickness of the second glass plate 12 is preferably 0.5 mm to 2.7 mm, more preferably 0.5 mm to 2.3 mm, and may be 0.5 mm to 1.8 mm. When the thickness of the second glass plate 12 is 0.5 mm to 2.7 mm, the weight of the vehicle window glass can be reduced and the second glass plate 12 can be easily handled.

[0017] For example, polyvinyl butyral (PVB) or ethylene-vinyl acetate copolymer (EVA) can be used for the interlayer 13. The interlayer 13 may have either a single-layer structure or a multiple-layer structure. The thickness of the interlayer 13 is preferably 0.5 mm to 3.0 mm, and more preferably 0.5 mm to 2.8 mm. When the thickness of the interlayer 13 is 0.5 mm to 3.0 mm, the vehicle window glass can be made lighter and sufficient impact resistance can be ensured.

[0018] As shown in Fig. 1, a vehicle window glass 1 according to this embodiment is provided with a reinforcing member 14a on a side edge 21 on the front side of the vehicle. Also, a reinforcing member 14b is provided on a side edge 22 on the rear side of the vehicle. By providing the reinforcing members 14a and 14b in this manner, the rigidity of the window glass can be increased.

[0019] Furthermore, the colored ceramic layers 16a and 16b are provided at positions corresponding to the positions of the reinforcing members 14a and 14b when the vehicle window glass 1 is viewed in plan view. By providing the colored ceramic layers 16a and 16b, the reinforcing members 14a and 14b can be made less visible from the outside.

[0020] 1 shows a configuration example in which reinforcing members 14a, 14b are provided on both the front and rear side edges 21, 22 of the vehicle. However, in this embodiment, reinforcing members 14a, 14b may be provided on only one of the front side edge 21 and the rear side edge 22 of the vehicle. In other words, in this embodiment, reinforcing members 14a, 14b may be provided on at least one of the front side edge 21 and the rear side edge 22 of the vehicle. Hereinafter, reinforcing members 14a, 14b will also be collectively referred to as reinforcing member 14. Similarly, colored ceramic layers 16a, 16b will also be collectively referred to as colored ceramic layer 16.

[0021] For example, the reinforcing member 14 may be provided on one of the longer sides of the vehicle window glass 1. Specifically, if the vehicle window glass 1 is a side glass at the front of the vehicle (corresponding to FIG. 1), the reinforcing member 14b may be provided on the side edge 22 of the vehicle window glass 1 on the rear side of the vehicle. Also, if the vehicle window glass 1 is a side glass at the rear of the vehicle, the reinforcing member 14a may be provided on the side edge of the vehicle window glass 1 on the front side of the vehicle. In this way, by providing the reinforcing member 14 on the longer side of the side edges of the vehicle window glass 1, the rigidity of the window glass can be effectively increased.

[0022] As shown in FIG. 2, the reinforcing member 14 is disposed between the first glass sheet 11 and the second glass sheet 12 in the thickness direction of the vehicle window glass 1. The reinforcing member 14 is disposed on the second glass sheet 12 side in the thickness direction of the vehicle window glass. Specifically, the reinforcing member 14 is disposed on the vehicle-exterior surface of the second glass sheet 12 in the thickness direction of the vehicle window glass. The reinforcing member 14 is a plate-shaped member extending in the up-and-down direction of the vehicle window glass 1 (see FIG. 1), and can be made of a metal material or a resin material. When the reinforcing member 14 is made of a metal material, stainless steel, cold-rolled steel sheet, spring steel, etc. can be used as the metal material. When the reinforcing member 14 is made of a resin material, glass fiber-reinforced PBT resin, AS resin, POM resin, etc. can be used as the resin material.

[0023] Additionally, colored ceramic layers 15, 16 are provided at positions corresponding to the positions where the reinforcing members 14 are provided. The colored ceramic layer 15 is formed on the vehicle interior surface of the second glass sheet 12 (the surface opposite the side in contact with the interlayer 13). The colored ceramic layer 16 is formed on the surface of the first glass sheet 11 in contact with the interlayer 13. The colored ceramic layers 15, 16 may be any color, but dark colors such as black, brown, gray, and navy blue are preferred, and black is more preferred. The colored ceramic layers 15, 16 may be formed, for example, by printing a black ceramic layer on the surfaces of the first glass sheet 11 and the second glass sheet 12. Specifically, the black ceramic layer may be formed by applying a ceramic color paste containing a black pigment and a meltable glass frit to the surfaces of both glass sheets and firing the paste.

[0024] Providing the colored ceramic layers 15, 16 makes it difficult to see the reinforcing member 14 from the outside. In particular, providing the colored ceramic layers 15, 16 on both the first glass plate 11 and the second glass plate 12 makes it difficult to see the reinforcing member 14 from both the outside and inside of the vehicle.

[0025] In this embodiment, the second glass sheet 12 is disposed on the interior side of the vehicle, and is configured so that a portion of the second glass sheet 12 abuts against the sealing member 30 via the colored ceramic layer 15. In other words, by providing the sealing member 30 so as to abut against the second glass sheet 12, it is possible to prevent water droplets, dust, and the like from entering the interior of the vehicle from outside. The sealing member 30 is formed, for example, on a B-pillar of the vehicle, and is formed so as to extend in the vertical direction of the vehicle window glass 1. The sealing member 30 is made of a resin material. The colored ceramic layer 15 is provided on the interior surface of the second glass sheet 12. Therefore, when the vehicle window glass 1 slides in the vertical direction, the colored ceramic layer 15 provided on the second glass sheet 12 and the sealing member 30 slide in abutment against each other.

[0026] With this configuration, the second glass sheet 12 can be protected by the colored ceramic layer 15, and abrasion of the second glass sheet 12 by the sealing member 30 can be suppressed. That is, in the present embodiment, by providing the colored ceramic layer 15 on the surface of the second glass sheet 12, the sealing member 30 can be prevented from directly abutting on the surface of the second glass sheet 12, and abrasion of the second glass sheet 12 by the sealing member 30 can be suppressed. Furthermore, abutting the second glass sheet 12 with the sealing member 30 via the colored ceramic layer 15 reduces frictional resistance that occurs when the vehicle window glass 1 slides up and down compared to when the sealing member 30 directly abuts on the surface of the second glass sheet 12, and therefore the vehicle window glass 1 can be raised and lowered smoothly.

[0027] 1, in this embodiment, when the vehicle window glass 1 is viewed from above, it is preferable that the reinforcing members 14a, 14b are arranged so that the belt molding 40 of the door panel 80 (see FIG. 7) to which the vehicle window glass 1 is attached intersects with the reinforcing members 14a, 14b. In other words, it is preferable that the reinforcing members 14a, 14b are arranged so as to straddle the belt molding 40. In FIG. 1, the positions corresponding to the belt molding 40 are indicated by dashed lines.

[0028] When the vehicle window glass 1 is attached to the door panel 80, the vehicle window glass 1 is clamped by the belt molding 40. Therefore, when the reinforcing members 14a, 14b are arranged so as to straddle the belt molding 40, the reinforcing members 14a, 14b are supported by the belt molding 40, and the rigidity of the vehicle window glass 1 is also improved.

[0029] When manufacturing the vehicle window glass 1 according to this embodiment, first, a first glass plate 11 having a colored ceramic layer 16 formed thereon, and a second glass plate 12 having a colored ceramic layer 15 formed thereon are prepared (see FIG. 2 ). A reinforcing member 14 is placed on the surface of the second glass plate 12 on which the interlayer film 13 is to be disposed. At this time, the reinforcing member 14 may be temporarily fixed to the surface of the second glass plate 12 using an adhesive material such as double-sided tape or adhesive. Thereafter, the first glass plate 11, the interlayer film 13, and the second glass plate 12 are laminated in this order, and the laminate is heated and pressurized to bond them together, thereby manufacturing the vehicle window glass 1. After bonding them together, the reinforcing member 14 is fixed (adhered) by the interlayer film 13.

[0030] As explained above, the vehicle window glass 1 according to this embodiment is provided with the reinforcing member 14 on at least one of the front side edge 21 and the rear side edge 22 of the vehicle window glass 1. This increases the rigidity of the vehicle window glass 1. In particular, in this embodiment, the reinforcing member 14 is provided so as to extend in the vertical direction of the vehicle, which effectively prevents the vehicle window glass 1 from bending when a force is applied to the upper side of the vehicle window glass 1.

[0031] Furthermore, when the vehicle window glass 1 is viewed from above, the colored ceramic layers 15, 16 are provided at positions corresponding to the positions where the reinforcing members 14 are provided, so that the reinforcing members 14 can be made difficult to see from the outside.

[0032] Next, modified examples of the vehicle window glass 1 according to the present embodiment will be described. Figures 3 to 6 are cross-sectional views showing other configuration examples of the vehicle window glass according to the embodiment. Figures 3 to 6 correspond to cross-sectional views taken along the cutting line II-II in Figure 1.

[0033] In this embodiment, as in the vehicle window glass 1a shown in Fig. 3, the reinforcing member 14 may be arranged on the first glass sheet 11 side in the thickness direction of the vehicle window glass 1a. Specifically, the reinforcing member 14 may be arranged on the surface of a colored ceramic layer 16 formed on the vehicle interior surface of the first glass sheet 11. In this way, when the reinforcing member 14 is arranged on the first glass sheet 11 side, the distance between the colored ceramic layer 16 and the reinforcing member 14 can be reduced, making the reinforcing member 14 less noticeable.

[0034] Furthermore, in this embodiment, as in a vehicle window glass 1b shown in Fig. 4, two reinforcing members 14_1 and 14_2 may be provided between the first glass sheet 11 and the second glass sheet 12. That is, the reinforcing members 14_1 and 14_2 may be provided on both the first glass sheet 11 side and the second glass sheet 12 side in the thickness direction of the vehicle window glass 1. For example, the reinforcing member 14_1 may be provided on the surface of the colored ceramic layer 16 formed on the vehicle interior surface of the first glass sheet 11, and the reinforcing member 14_2 may be provided on the vehicle exterior surface of the second glass sheet 12. When two reinforcing members 14_1 and 14_2 are provided in this manner, the rigidity of the vehicle window glass can be further increased.

[0035] In the present embodiment, the reinforcing member 14 may be disposed so as to be sandwiched between the interlayer film 13_1 and the interlayer film 13_2 in the thickness direction of the vehicle window glass 1c, as in the vehicle window glass 1c shown in Fig. 5. The vehicle window glass 1c shown in Fig. 5 may be manufactured by laminating the first glass plate 11, the interlayer film 13_1, the reinforcing member 14, the interlayer film 13_2, and the second glass plate 12 in this order, and then heating and pressuring the laminate to bond them together.

[0036] 5, the interlayer film 13_1 and the interlayer film 13_2 are shown separately for the sake of explanation, but the interlayer film 13_1 and the interlayer film 13_2 are heated and pressurized during manufacturing to fuse and become one body. In the vehicle window glass 1c shown in FIG. 5, the reinforcing member 14 is sandwiched between the interlayer film 13_1 and the interlayer film 13_2, so that the reinforcing member 14 can be prevented from directly contacting the first glass sheet 11 or the second glass sheet 12.

[0037] In this embodiment, as in a vehicle window glass 1d shown in Fig. 6, the reinforcing member 17 may have an L-shaped cross section perpendicular to the direction in which the reinforcing member 17 extends (the vertical direction of the vehicle). In this case, the reinforcing member 17 is disposed on the second glass sheet 12 side in the thickness direction of the vehicle window glass 1d and is disposed so as to cover the end of the second glass sheet 12. In other words, the L-shaped plate-like portion 18 of the reinforcing member 17 is disposed so as to cover the end of the second glass sheet 12, including the side surface. By forming the reinforcing member 17 in an L-shaped cross section in this way, the rigidity of the reinforcing member 17 can be increased. Therefore, the rigidity of the vehicle window glass 1d can also be increased.

[0038] In this case, the second glass plate 12 may be configured to be shorter than the first glass plate 11 toward the center in the in-plane direction of the vehicle window glass at the side of the vehicle window glass 1d on which the reinforcing member 17 is provided, so that the corner portion 19 of the reinforcing member 17 overlaps with the first glass plate 11. In other words, as shown in Fig. 6, by making the length of the second glass plate 12 shorter than the length of the first glass plate 11 by a distance d, the corner portion 19 of the reinforcing member 17 can be made to overlap with the first glass plate 11. This makes it possible to make the reinforcing member 17 less noticeable when the vehicle window glass 1d is viewed in plan from outside the vehicle.

[0039] Fig. 7 is a plan view seen from outside the vehicle showing an example of the configuration of a sashless door according to an embodiment, and is a diagram showing an example of a sashless door configured using the vehicle window glass shown in Fig. 1. As shown in Fig. 7, the sashless door 100 according to this embodiment includes the vehicle window glass 1 described above and a door panel 80 to which the vehicle window glass 1 is attached. A belt molding 40 is provided on the upper side of the door panel 80. The belt molding 40 holds the vehicle window glass 1 in a state in which the vehicle window glass 1 can move up and down.

[0040] As shown in Fig. 1, holders 50_1 and 50_2 for holding the vehicle window glass 1 are attached to the underside of the vehicle window glass 1. The vehicle window glass 1 is held by the holders 50_1 and 50_2, and these holders 50_1 and 50_2 are fixed to an elevator device (not shown) provided inside the door panel 80. The vehicle window glass 1 moves up and down by the driving force of the elevator device (not shown). Note that although Fig. 7 illustrates a left front side door as an example of a sashless door, the same configuration can be applied to side doors at other positions.

[0041] The present invention has been described above in accordance with the above-described embodiment, but the present invention is not limited to the configuration of the above-described embodiment, and naturally includes various modifications, alterations, or combinations that a person skilled in the art could make within the scope of the invention claimed in the claims of this application.
