Description

The present invention relates to glass with a plastic frame for vehicle windows.

A structure of glass with a resin frame for vehicle windows is known as glass that is fixed to the window opening of a vehicle. For example, Patent Document 1 discloses glass with a resin frame for vehicle windows, which comprises a glass sheet, a resin frame (molding) formed by injection molding on the periphery of the glass sheet, and a clip (retainer) for fixing the glass with a resin frame for vehicle windows until the adhesive for attaching the glass with a resin frame for vehicle windows to the window opening of the vehicle hardens, the clip being implanted in the bulge of the resin frame.

Publication No. 5-009212

In the resin-framed vehicle window glass of Patent Document 1, the clip seat (head) is formed to be located inside the resin frame. However, in the resin-framed vehicle window glass of Patent Document 1, the clip seat is high and there are many gaps in the seat that are filled with resin, so when force is applied to the clip, the adhesion between the clip seat and the resin frame is lost, causing the clip to wobble. This wobbling of the clip can lead to poor installation accuracy in the window opening and the generation of abnormal noises while driving.

The present invention was made in consideration of the above problems, and aims to provide a glass with a plastic frame for vehicle windows that can suppress the wobbling of the clip.

The vehicle window glass with a resin frame of the embodiment is a glass with a resin frame for a vehicle window, which is integrally formed with a glass sheet, a resin frame that is arranged on the periphery of the glass sheet, and a clip that is attached to a resin base that is arranged on the glass sheet. The base is arranged on the interior side of the glass sheet when the vehicle window glass with a resin frame for a vehicle window is installed in a vehicle, and the clip has a seat portion that is embedded inside the base, and the seat portion has a first surface portion that faces the interior side of the glass sheet and a second surface portion that faces the opposite side of the glass sheet from the first surface portion. The seat has a second surface located on the side of the seat and a connecting portion connecting the first surface and the second surface, and the peripheral portion of the connecting portion has a recessed portion with the resin constituting the base interposed therebetween, and the ratio of the first distance from the surface of the glass plate facing the vehicle interior to the surface of the first surface facing the glass plate to the surface of the second surface facing the opposite side to the glass plate is 14% to 50%, and in a cross section passing through the seat portion and parallel to the glass plate, the ratio of the area of the recessed portion to the area of the first surface is 25% to 50%.

The vehicle window glass with plastic frame of the present invention can prevent the clip from wobbling, improve the accuracy of installation to the window opening, and suppress the generation of abnormal noise while driving.

[Vehicle window glass with plastic frame]
The resin-framed glass 10 shown in Fig. 1 is a fixed window of an automobile, and is used, for example, as a rear quarter glass of an automobile. The resin-framed glass 10 includes a glass sheet 12 and a resin frame 14 provided on the periphery of the glass sheet 12.

Furthermore, the resin-framed glass 10 is provided with a clip 18 that is attached to a resin base 16 that is placed on the glass plate 12. The base 16 is placed on the interior surface of the glass plate when the resin-framed glass 10 is installed in a vehicle. Note that the resin-framed glass 10 is not limited to a rear quarter glass. It may be a front bench glass or a roof glass. It may also be a windshield or rear glass. The resin-framed glass 10 is finally adhered and fixed to the window opening of the vehicle with an adhesive.

<Glass plate>
The glass plate 12 shown in FIG. 1 is formed in a substantially quadrangular (trapezoidal) shape in plan view. However, the shape of the glass plate 12 is not limited to a substantially quadrangular shape, and may be a substantially triangular shape, etc. The glass plate 12 may be inorganic glass or organic glass. As the inorganic glass, for example, soda-lime glass, aluminosilicate glass, borosilicate glass, alkali-free glass, quartz glass, etc. are used without any particular limitation. Among these, soda-lime glass is particularly preferable from the viewpoint of manufacturing cost and formability. The forming method of the glass plate 12 is not particularly limited. For example, in the case of inorganic glass, a glass plate formed by a float method or the like is preferable.

When the glass plate 12 is inorganic glass, the glass plate 12 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, and may be either air-cooled tempered glass or chemically tempered glass.

When the tempered glass is physically tempered glass (e.g., air-cooled tempered glass), the glass surface may be strengthened by generating a compressive stress layer on the glass surface due to the temperature difference between the glass surface and the inside of the glass by an operation other than slow cooling, such as rapidly cooling the glass plate uniformly heated during bending from a temperature near the softening point. When the tempered glass is chemically tempered glass, the glass surface may be strengthened by generating a compressive stress on the glass surface by an ion exchange method or the like after bending. In addition, glass that absorbs ultraviolet or infrared rays may be used as the glass plate 12. The glass plate 12 is preferably transparent, but may be a glass plate that is colored to the extent that transparency is not impaired.

The glass sheet 12 may have a single curved shape formed by bending in only one direction, or may have a compound curved shape formed by bending in two directions (for example, a specific direction and a direction perpendicular to the specific direction). Gravity forming, press forming, roller forming, or the like is used to bend the glass sheet 12. When the glass sheet 12 is bent to a specific curvature, the radius of curvature of the glass sheet 12 may be 1,000 to 100,000 mm.

The glass plate 12 may be a single glass plate, or may be, for example, laminated glass in which two or more glass plates are bonded together via an interlayer. As an example of the interlayer of the laminated glass, a known thermoplastic resin film such as polyvinyl butyral (PVB) or ethylene vinyl acetate copolymer (EVA) is used. The interlayer of the laminated glass may be transparent or colored. The interlayer may also be two or more layers.

When the glass plate 12 is a laminated glass, the thickness of the glass located on the outside and the thickness of the glass located on the inside when the glass plate 12 is attached to a vehicle may be the same or different. When the glass plate 12 is attached to a vehicle, the thickness of the glass located on the outside is preferably 1.0 mm or more and 3.0 mm or less. When the thickness of the glass plate located on the outside is 1.0 mm or more, the strength of the stone chip resistance performance is sufficient, and when it is 3.0 mm or less, the mass of the laminated glass does not become too large, which is preferable in terms of fuel efficiency of the vehicle. The thickness of the glass plate located on the inside is preferably 0.3 mm or more and 2.3 mm or less. When the thickness of the glass plate located on the inside of the vehicle is 0.3 mm or more, the handling property is good, and when it is 2.3 mm or less, the mass does not become too large. If the thickness of the glass located on the outside and the thickness of the glass located on the inside are each 1.8 mm or less, it is preferable that the glass plate 12 can be both lightweight and soundproof. In addition, when the thickness of the glass located on the inside is 1.0 mm or less, the glass located on the inside may be chemically strengthened glass. If the glass located on the inside is chemically strengthened glass, it is preferable that the compressive stress value of the glass surface is 300 MPa or more and the depth of the compressive stress layer is 2 μm or more.

When the glass plate 12 is a single glass plate, it is preferable that the glass plate 12 is air-cooled tempered glass, and in this case, it is preferable that the thickness of the glass plate 12 is 1.8 mm or more and 5.0 mm or less.

When the glass plate 12 is made of organic glass, examples of the material for the organic glass include transparent resins such as polycarbonate or acrylic resins (e.g., polymethyl methacrylate).

The glass plate 12 preferably has a shielding region 20 on the outer periphery of the surface on the inside of the vehicle. The shielding region 20 is formed, for example, by applying a ceramic color paste containing a fusible glass frit containing a black pigment and then firing it. The shielding region 20 forms a black opaque layer on the periphery of the glass plate 12. The shielding region 20 blocks visibility from the outside. The shielding region 20 is also formed so as to cover the formation region of the frame 14 and the base 16 described below. Note that various suitable films may be formed as a surface layer of the glass plate 12 from the viewpoint of improving weather resistance and functionality such as hydrophilicity and water repellency.

<Resin frame>
As an example, the resin frame 14 is provided so as to surround the entire periphery of the glass plate 12. Examples of materials for the resin frame 14 include synthetic resins such as polyvinyl chloride (PVC) and thermoplastic elastomer (TPE). The frame 14 is provided on the peripheral portion of the glass plate 12 by mounting the glass plate 12 in a mold having a cavity corresponding to the shape of the frame 14 and injecting the above-mentioned synthetic resin (molten synthetic resin) into the cavity.

2, the frame 14 has an exterior side portion 14A that contacts the exterior side surface 12A of the glass plate 12, an interior side portion 14B that contacts the interior side surface 12B, and a connecting portion 14C that contacts the end surface 12C and connects the exterior side portion 14A and the interior side portion 14B. The frame 14 is a so-called three-sided molding. The frame 14 may be provided with a lip 14D that extends to the side opposite the glass plate 12. The lip 14D contacts the vertical wall of the mounting portion of the window opening (not shown).

The frame 14 may be a two-sided molding consisting of an interior portion 14B and a connecting portion 14C that contact the interior side surface 12B and end surface 12C of the glass plate 12, or a one-sided molding that contacts only the interior side surface 12B of the glass plate 12.

<Base and clip>
1 and 2, when the resin-framed glass 10 is installed in a vehicle, the resin base 16 is disposed on the interior side surface 12B of the glass sheet 12. The frame 14 and the base 16 are integrally molded from the same type of resin material.

The frame body 14 and the base 16 may be spaced apart from each other as shown in Figs. 1 and 2, or the frame body 14 and the base 16 may be continuous with each other. The base 16 is located on the interior side surface 12B of the vehicle, closer to the center of the glass plate 12 than the frame body 14. In Fig. 1, four bases 16 are located at the four corners of the glass plate 12, each spaced apart from the frame body 14.

A clip 18 is attached to each base 16. Generally, the resin-framed glass 10 is fixed to the window opening of the vehicle with a urethane-based adhesive (not shown). The resin-framed glass 10 is prevented from shifting or floating up from the window opening by inserting the clip 18 into the mounting hole of the window opening until the adhesive hardens.

The bases 16 and clips 18 are arranged in appropriate positions and in appropriate numbers so that they can fully perform the above functions. For example, the bases 16 and clips 18 are set so as to be scattered along the outer edge of the glass plate 12 inside the frame 14. In this case, the bases 16 and clips 18 are positioned closer to the center of the glass plate 12 than the area where the adhesive is applied. The adhesive can seal out water that may enter through the mounting hole in the window opening via the clips 18.

Figure 3 is a perspective view of the clip 18. As shown in Figures 2 and 3, the clip 18 includes a seat portion 22 embedded inside the base 16, and an elastically deformable shaft portion 30 provided on the seat portion 22 and extending in the direction opposite to the glass plate 12.

The seat surface 22 has a first surface 23 facing the interior side surface 12B of the glass plate 12, a second surface 24 located on the opposite side of the first surface 23 to the interior side surface 12B of the glass plate 12, and a connecting portion 25 connecting the first surface 23 and the second surface 24. Furthermore, the connecting portion 25 has a recessed portion 26 at its periphery where the resin constituting the base 16 is inserted.

The elastically deformable shaft portion 30 includes a shaft body 31 extending from the second surface portion 24, and an engagement portion 32 on each side of the shaft body 31. The engagement portion 32 is connected to the tip side of the shaft body 31, and extends away from the shaft body 31 toward the base end side of the shaft body 31. In other words, the gap between the shaft body 31 and the engagement portion 32 becomes larger toward the base end side. The engagement portion 32 can elastically deform with the connection portion with the shaft body 31 as a fulcrum.

When the glass 10 with the resin frame is temporarily fixed to the window opening, the shaft portion 30 of the clip 18 is inserted into the mounting hole of the window opening. At that time, the engaging portion 32 elastically deforms, and when it passes through the mounting hole, the engaging portion 32 returns to its original state and engages with the mounting hole, functioning as a retainer.

A seal flange portion 40 is provided between the engagement portion 32 and the seat portion 22 on the base end side of the shaft body 31. The seal flange portion 40 has a bowl shape with an opening on the side opposite the glass plate 12. When the seal flange portion 40 abuts against the window opening, it elastically deforms in a direction that lowers the height of the seal flange portion 40, thereby sealing the periphery of the mounting hole.

Clip 18 is preferably made of a thermoplastic resin. Examples of thermoplastic resins that can be used include POM (polyacetal), PBT (polybutylene terephthalate), PP (polypropylene), PE (polyethylene), PA (polyamide), and PVC (polyvinyl chloride). These thermoplastic resins can contain 10% to 50% glass fiber by weight, which can improve the strength of clip 18. The weight ratio of glass fiber is preferably 15% to 30%.

Next, the first feature of the resin-framed glass 10 of the embodiment will be described with reference to FIG. 2. In the resin-framed glass 10, the distance between the interior side surface 12B of the glass sheet 12 and the seat surface portion 22 is important to suppress the wobbling of the clip 18.

In the embodiment of the resin-framed glass 10, the ratio r1 (L1/L2 x 100) of the first distance L1 from the interior side 12B of the glass sheet 12 to the surface of the first surface 23 facing the glass sheet 12 to the second distance L2 from the interior side 12B of the glass sheet 12 to the surface of the second surface 24 opposite the glass sheet 12 is set to a range of 14% to 50%.

By setting the ratio r1 to 14% or more, the first distance L1 from the interior side surface 12B of the glass sheet 12 to the surface of the first surface portion 23 facing the glass sheet 12 can be shortened, and the cooling time can be shortened. By setting the ratio r1 to 50% or less, the distance between the seat portion 22 and the glass sheet 12 can be shortened, and wobbling can be effectively suppressed. The ratio r1 is more preferably 25% or more and 40% or less, and even more preferably 25% or more and 33% or less.

The first distance L1 is preferably 0.5 mm or more and 3 mm or less, more preferably 0.5 mm or more and 1.5 mm or less, and even more preferably 1 mm or more and 1.5 mm or less.

The second distance L2 is preferably 3.5 mm or more and 6 mm or less, more preferably 3.5 mm or more and 5 mm or less, and even more preferably 3.5 mm or more and 4 mm or less.

The first distance L1 and the second distance L2 are determined so that the ratio r1 is in the range of 14% or more and 50% or less.

From the viewpoint of preventing buckling due to injection pressure, the thickness of the second surface portion 24 is preferably 1 mm or more and 3 mm or less, more preferably 1.2 mm or more and 3 mm or less, and even more preferably 1.5 mm or more and 3 mm or less.

In addition, from the viewpoint of maintaining the pull-out strength of the clip 18 relative to the base 16, the thickness of the first surface portion 23 is preferably 1 mm or more and 3 mm or less, more preferably 1.2 mm or more and 3 mm or less, and even more preferably 1.5 mm or more and 3 mm or less.

Next, the second feature of the resin framed glass 10 of the embodiment will be described with reference to FIG. 4. FIG. 4(A) is a cross-sectional view before the resin R constituting the base 16 is interposed in the recessed portion 26. As shown in FIG. 4(A), the recessed portion 26 in which the resin constituting the base 16 is interposed is formed on the periphery of the connecting portion 25. In the cross-sectional view, the recessed portion 26 is formed in an area where the connecting portion 25 and the first surface portion 23 do not overlap. In FIG. 4(A), the first surface portion 23 has an elliptical shape in cross section. Here, the first surface portion 23 is an ellipse whose major axis is in the left-right direction of the paper and whose minor axis is in the up-down direction of the paper. However, the first surface portion 23 is not limited to an elliptical shape. In addition, although not shown, the second surface portion 24 may also have an elliptical shape similar to that of the first surface portion 23, or may have a different shape. It is preferable that the first surface portion 23 and the second surface portion 24 have the same shape and the same size.

Figure 4 (B) is a cross-sectional view of the base 16 after the resin R that constitutes the base is inserted into the recess 26. The overlapping area between the resin R inserted into the recess 26 and the first surface 23 determines the pull-out strength of the clip 18 relative to the base 16, so this area is important in preventing wobbling.

In the embodiment, the glass 10 with a resin frame has a ratio r2 (S1/S2 x 100) of the area S1 of the recessed portion 26 to the area S2 of the first surface portion 23 in a cross section passing through the seat portion 22 and parallel to the glass plate 12, which is in the range of 25% to 50%.

By making the ratio r2 25% or more, the pull-out strength of the clip 18 against the base 16 can be ensured. Furthermore, by making the ratio r2 50% or more, the filling of the resin R can be ensured. The ratio r2 is more preferably 30% or more and 40% or less, and even more preferably 30% or more and 35% or less.

The area S1 is preferably 75 ^mm2 or more and 100 ^mm2 or more, and more preferably 80 mm2 ^{or more} and 90 ^mm2 or more. The area S2 is preferably 250 mm2 or ^more and 300 ^{mm2 or more} , and more preferably 260 mm2 ^{or more} and 290 ^mm2 or more. The areas S1 and S2 are determined so that the ratio r2 is in the range of 25% or more and 50% or less.

As shown in FIG. 4(A), in cross section, the connecting portion 25 has multiple protrusions 27. The multiple protrusions 27 of the connecting portion 25 define the shape of the recessed portion 26 in cross section. When resin R is interposed in the recessed portion 26, the multiple protrusions 27 can restrict movement of the clip 18 in the rotational direction relative to the base 16 when the shaft portion 30 serves as the axis of rotation. As a result, wobbling of the clip 18 can be suppressed.

In FIG. 4(A), the multiple protrusions 27 include three types of protrusions 27A, 27B, and 27C. At least one of the multiple protrusions 27 may be a T-shaped protrusion 27A. The T-shaped protrusion 27A is formed by combining a vertical portion and a horizontal portion, and the vertical portion connects approximately at the center of the horizontal portion. The vertical portion and the horizontal portion are approximately perpendicular to each other. The vertical portion of the T-shaped protrusion 27A is located toward the center of the connecting portion 25, and the horizontal portion is located toward the outer periphery. As shown in FIG. 4(B), the T-shaped protrusion 27A can have resin R interposed from both sides of the vertical portion, and the seat portion 22 is firmly held by the base 16.

In FIG. 4(A), the T-shaped protrusions 27A are line-symmetrical about the vertical portion, but are not limited to line-symmetrical. Also, the two T-shaped protrusions 27A are positioned opposite each other, but the number and positions at which they are positioned are not particularly limited.

At least two of the multiple protrusions 27 are hook-shaped protrusions 27B that mutually regulate the direction of rotation when the shaft portion 30 is the axis of rotation. The hook-shaped protrusions 27B form an acute angle with the valley portion 28. As shown in FIG. 4(B) , resin R is likely to be interposed between the hook-shaped protrusions 27B and the valley portion 28. When the major axis and minor axis of the first surface portion 23 are axes of symmetry, the two protrusions 27B that are positioned in line symmetry are arranged in directions that regulate the direction of rotation. On the other hand, when the rotation axis of the shaft portion 30 is the center of symmetry, the two protrusions 27B that are positioned in point symmetry are arranged to face the same direction.

By providing at least two hook-shaped protrusions 27B that regulate the direction of rotation of each other, the movement of the clip 18 in the direction of rotation relative to the base 16 can be regulated, and wobbling of the clip 18 can be suppressed.

In FIG. 4(A), the multiple protrusions 27 may be rectangular protrusions 27C. The rectangular protrusions 27C occupy a large area in cross section. By adjusting the size of the rectangular protrusions 27C, the ratio r2 can be easily adjusted to a range of 25% to 50%.

Although not shown, at least one of the multiple protrusions 27 may be L-shaped. The L-shaped protrusion is formed by combining a vertical portion and a horizontal portion, and the ends of the vertical portion and the horizontal portion are connected to each other. The vertical portion and the horizontal portion are approximately perpendicular to each other. As with the T-shaped protrusion 27A, the L-shaped protrusion is likely to have resin R interposed between it and the valley portion 28, and the seat portion 22 is firmly held by the base 16.

Although not shown, the protrusion 27 may be gear-shaped. For example, the gear-shaped protrusion may be tapered and protrude radially outward from the center of the connecting portion 25, and multiple protrusions of the same shape may be evenly arranged around the outer periphery of the connecting portion 25.

The shape of the protrusion 27 is not limited to a specific shape as long as it can suppress wobbling.

[Manufacturing process of glass with resin frame]
Next, an example of a manufacturing process for the resin-framed glass 10 will be described with reference to the mold 80 shown in Fig. 5. Note that Fig. 5 shows a diagram in which the molten resin 85 that will become the frame 14 has already been injected into the cavity 83 of the mold 80, and the molten resin 85 that will become the base 16 has already been injected into the cavity 84. In the following explanation, the state before the molten resin 85 is injected into the cavities 83 and 84 will be described.

As shown in FIG. 5, the lower mold 82 is formed with a recess 86 that opens into the upper mold 81. The vertical cross section of the recess 86 is roughly stepped, with a deep recess and a shallow recess. The seating surface portion 22 of the clip 18 is attached to the shallow recess of the recess 86. The shaft portion 30 is also disposed in the deep recess, with the tip of the shaft portion 30 contacting the bottom of the deep recess. The glass plate 12 is attached to a predetermined position of the lower mold 82, and a cavity 84 is formed by the glass plate 12, the seating surface portion 22 of the clip 18, and the shallow recess of the recess 86. The shallow recess has a step for positioning the seating surface portion 22.

After this, the upper die 81 of the mold 80 is fixed to the lower die 82. This forms a cavity 83 between the lower die 82 and the upper die 81.

Next, molten resin 85 is injected into cavities 83 and 84 from a resin injection port (not shown). As a result, molten resin 85 fills cavities 83 and 84, and is filled in cavities 83 and 84. Thereafter, when molten resin 85 solidifies, lower mold 82 and upper mold 81 are separated from each other. A resin-framed glass 10 is manufactured in which glass plate 12, a resin frame 14 placed on the periphery of glass plate 12, and a clip 18 attached to a resin base 16 placed on the glass plate are integrally molded.

When the molten resin 85 is injected into the cavity 84, the seating surface portion 22 of the clip 18 functions as a lid member that separates the deep recess from the shallow recess. Therefore, the seating surface portion 22 prevents the molten resin 85 from flowing into the deep recess of the recess 86. On the other hand, the seating surface portion 22 receives pressure from the injected molten resin 85, and the shaft portion 30 is pressed against the bottom of the deep recess of the recess 86. If the seating surface portion 22 of the clip 18 is shaped so that the molten resin 85 penetrates or flows into the center of the seating surface portion 22, the injection pressure of the molten resin 85 that flows in may cause the seating surface portion 22 of the clip 18 to buckle in the direction of the tip of the shaft portion 30. However, in the seating surface portion 22 of the clip 18 of the embodiment of the present invention, the molten resin 85 does not flow into the center of the seating surface portion 22, so that the buckling deformation of the seating surface portion 22 of the clip 18 can be suppressed. In addition, as shown in FIG. 5, the shaft portion 30 has a flat portion 33 at its tip, which prevents the clip 18 from buckling when the flat portion 33 receives the injection pressure of the molten resin 85.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above examples, and various improvements and modifications may be made without departing from the spirit of the present invention.
