Description

TECHNICAL FIELD The present invention relates to a resin window panel used for a vehicle or the like.

2. Description of the Related Art As shown in, for example, Japanese Utility Model Application Laid-Open No. 64-44106, a resin window panel used for a vehicle or the like is formed by injecting a liquid molten resin into a molding die.

That is, as shown in FIG.
The transparent films 3A and 3B are attracted by, for example, a magnet 5 and attached to the inner wall of the device. The films 3A and 3B are smaller in size than the space 2 in order to improve the workability of mounting the film 3 in the space 2 and in consideration of dimensional variations. Then, the molten resin 4 is injected into the space 2 to which the films 3A and 3B are attached. Then, when the molten resin 4 is solidified and then taken out of the molding die 1, it becomes a transparent window panel in which the films 3A and 3B are welded to the surface of the panel body.

Although the films 3A and 3B are for protecting the panel body, since the films 3A and 3B are smaller in size than the space 2 of the molding die 1 as described above, It will be welded to the surface inside the end of the panel body.

Therefore, the ends of the panel main body are not covered with the films 3A and 3B, and are likely to be scratched. Therefore, as shown in FIG. 2, the molding 9 is attached to the peripheral portion of the panel main body 6 by post-installation or insert molding, and the end 8 of the panel main body 6 is covered by the edges 8 of the films 3A and 3B. (See Jpn. Pat. Appln. KOKAI Publication No. 64-22511).

A panel body 6 whose end 8 is protected by a molding 9 is referred to as a window panel 7 as a vehicle body outer panel.
It can be attached to 10.

Problems to be Solved by the Invention By the way, in the above-mentioned conventional window panel 7, a step ΔH occurs between the surface of the window panel 7 and the surface of the molding 9, and a flash surface between the panel 7 and the molding 9 is formed. That is, planarization cannot be performed, and there is a disadvantage that dust, wax, and the like easily accumulate on the step ΔH.

Therefore, as shown in FIG.
The peripheral edge of the panel body 6 is thinned.
It is conceivable to attach a molding 9 to the thinned portion to achieve a flash surface.

However, when the step portion 11 is formed on the panel main body 6, the film 3A must be properly welded along the shape of the step portion 11. Therefore, the film 3A is bent at a right angle by the preform,
It is necessary to keep it habitual. However, this causes a problem that the bent portion of the film 3A is cracked or whitened, and the window panel 7 becomes a defective product.

Therefore, conventionally, it has been difficult to make the window panel 7 a flash surface.

Means for Solving the Problems Therefore, a resin window panel according to the present invention is a resin panel body formed by injecting a molten resin into the space in a state where a film is arranged on an inner wall of a space of a molding die. Simultaneously with forming, a thin portion having an inclined surface with a small bending angle is formed on the peripheral portion of the panel main body, and the edge of the film is disposed at an intermediate position of the inclined surface to form the panel main body. The film is welded to a surface in a range inner than the end, and a molding covering the edge of the film and the end of the panel main body is arranged on the peripheral edge of the panel main body, and the molding is provided on the inclined surface side of the molding. The outer surface is formed to be substantially flush with the surface of the panel body.

Function The bending angle of the film welded to the surface of the panel body is small, this film does not crack or whiten, and the flash between the molding attached to the periphery of the panel body and one surface of this panel body Surface conversion, that is, planarization can be easily performed.

Embodiment FIG. 1 is a partial sectional view of an embodiment of the present invention.

In the figure, 13 is a transparent resin panel body,
The peripheral portion of the panel body 13 is a thin portion 16 having an inclined surface. The panel body 13 is formed by a molding die as described above, and a molten resin is injected into the space in a state where a film is disposed on an inner wall of a space of the molding die, and a peripheral edge is formed. At the same time as molding a resin panel body 13 having a thin portion 16 having a small inclined surface with a small bending angle at the portion, the edge portion of the film is disposed at an intermediate position of the inclined surface. The film is welded to the surface in the area inside the end of the panel body 13. That is, one surface of the panel body 13 (upper surface in the drawing)
For example, a transparent film base portion 14A made of, for example, polycarbonate is disposed with its edge on the inclined surface of the thin portion 16, and is welded to a surface inside the end portion 20 of the panel body 13. Then, on this film base portion 14A, for example, a transparent film hard coat portion 15 made of a silicon-based material is used.
A is formed in the same size as the film base 14A.
And the other surface of the panel body 13 (the lower surface on the drawing)
For example, a transparent film base portion 14B made of polycarbonate of the same material as the film base portion 14A is welded to a surface inside the end portion 20 of the panel main body 13. On the film base portion 14B, for example, a transparent film hard coat portion 15B made of the same silicon-based material as the film hard coat portion 15A is formed in the same size as the film base portion 14B. Further, a masking portion 18 is formed on the periphery of the film hard coat portion 15B. The masking section 18 is for masking an adhesive 19 described later. A molding 17 is provided on the thin portion 16 at the peripheral edge of the panel body 13 by the film base portions 14A, 14A.
B, the film hard coat portions 15A and 15B and the end portion 20 are attached so as to cover the outer surface on the inclined surface side of the molding 17, one surface of the panel body 13, that is, the inclined surface of the thin portion 16 is attached. The flash surface is formed substantially flush with the outer surface on the formed side. And
As described above, the panel main body 13 including the film base portions 14A and 14B, the film hard coat portions 15A and 15B, the masking portion 18 and the molding 17 is attached to the vehicle body outer plate portion 10 as the window panel 12. In this case, the other surface of the window panel 12, that is, the surface on which the masking portion 18 is formed is opposed to the vehicle body outer plate portion 10, and the masking portion 18 and the vehicle body outer plate portion 10 are bonded by the adhesive 19. Things.

In the drawings, the thicknesses of the film base portions 14A and 14B, the film hard coat portions 15A and 15B, and the masking portion 18 are exaggerated for convenience of the drawing.

As described above, if the peripheral portion of the panel body 13 is the thin portion 16 having an inclined surface, the film base portion 14A and the film hard coat portion 15A do not need to be bent at a right angle as shown in FIG. Since the bending angle may be small, the film base portion 14A and the film hard coat portion 15A will not be cracked or whitened, and the product defect of the window panel 12 can be prevented. Moreover, the flash surface of the molding 17 and one surface of the panel body 13 can be easily formed.

Further, since the rate of change of the thickness of the peripheral portion of the panel body 13 and the rate of change of the thickness of the molding 17 can be reduced, the molding of the peripheral portion and the molding 17 becomes easy.

Further, by making the peripheral portion of the panel main body 13 a thin portion having an inclined surface, the contact area between the peripheral portion of the panel main body 13 and the film base portion 14A and the peripheral portion and the molding 17 can be widened. Therefore, the welding strength between the peripheral portion and the film base portion 14A, and the peripheral portion and the molding 17
Can be increased in mounting strength.

In the example described above, the film base portion 14A,
Although 14B is made of a polycarbonate material and the film hard coat portions 15A and 15B are made of a silicon-based material, the material is not limited to these materials and may be made of other materials.

Effect of the Invention As described above, according to the present invention, the bending angle of the film welded to the surface of the panel body is reduced by making the peripheral portion of the resin window panel body a thin portion having an inclined surface. Therefore, the film is not cracked or whitened, and a defective product of the window panel can be prevented. In addition, since there is no step between the surface of the molding attached to the periphery of the panel body and one surface of this panel body, it is easy to make the molding and the panel body a flush surface, that is, to make it flat. It can be carried out.

Further, since the rate of change of the thickness of the peripheral portion of the panel body and the rate of change of the thickness of the molding can be reduced, the molding of the peripheral portion and the molding can be facilitated.

Further, by making the peripheral portion of the panel main body a thin portion having an inclined surface, the contact area between the peripheral portion of the panel main body, the film, and the peripheral portion and the molding can be widened. The welding strength between the portion and the film and the mounting strength between the peripheral portion and the molding can be increased.
