BACKGROUND OF THE INVENTION
The present invention relates to a resin window suitable as, for example, a sunroof or a quarter window of an automobile.
[0002]
[Prior art]
As this type of conventional resin-made windows, for example, those described in JP-A-11-91346 are known.
FIG. 7 shows a cross-sectional structure of the resin window described in the above publication. As shown in the figure, the resin window is formed by bonding resin films 102 and 103 to the vehicle outer surface side and the vehicle inner surface side of the panel main body 101 made of a hard resin material, respectively. A colored coating portion 104 is provided on the peripheral portion of the vehicle outer side film 102 on the inner surface side of the vehicle, and the colored coating portion 104 is formed by an integrated effect production function portion 104a having an outer peripheral edge similar in color to the outer plate color. The inner side is formed by a dot coating portion 104b having the same color as the unity effect production function portion 104a.
Further, a gray or black colored coating portion 105 (so-called blackout) is provided on the outer peripheral edge portion on the inner surface side of the resin film 103 on the inner side of the vehicle. The colored coating portion 105 is provided to protect the adhesive 107 that bonds the window panel to the vehicle body panel 106 from the sun rays so that it is hidden from the outside of the vehicle and is not visible. It is closer to the inside than the inner peripheral edge of the integrated effect function unit 104a.
[0003]
[Problems to be solved by the invention]
According to the resin window described in the above publication, it is possible to bring out a sense of unity with the color of the outer plate of the vehicle body and to suppress deterioration of the adhesive. However, when the above-mentioned resin window is viewed from the inside of the vehicle, the dot coating portion 104b can be directly seen, and the dot coating portion 104b is composed of the same color as the integrated feeling effect function portion 104a of the same color as the vehicle body outer plate color. Therefore, there is a problem that it is not possible to achieve harmony with the color inside the vehicle even if the appearance from the outside of the vehicle can be improved.
[0004]
The present invention has been made in view of the above-mentioned conventional problems, and the object of the present invention is to make the resin effective not only in harmony with the color of the outer plate of the vehicle body but also in harmony with the color of the vehicle interior. To provide windows.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, a resin window according to the present invention has a configuration as described in each claim.
Therefore, according to the resin window of the first aspect of the invention, the outer plate color dot printing layer having the same color as the outer plate color can be seen from the outside of the vehicle, and the base color dot printing layer having a hue corresponding to the inner color from the inside of the vehicle. Will be visible. For this reason, the exterior appearance can be improved by creating a sense of unity with the exterior color of the vehicle body outside the vehicle, while the interior can be harmonized with the color inside the vehicle, creating a calm atmosphere. Can be produced.
In the invention of claim 1, when the resin window is formed by in-mold molding, the panel main body and the resin film can be welded through the non-printing portion formed by the gaps between the dots of the dot printing layer. it can.
[0006]
According to the second aspect of the present invention, when the base color dot print layer is overlaid on the outer plate color dot print layer and printing is performed, even if positional deviation occurs in the dots of both print layers, The positional deviation can be absorbed within the range.
In addition, when viewed from the outside of the vehicle, in dot units, the base color dot print layer surrounds the outer plate color dot print layer that is the same color as the outer plate color. Since it is common to use a light and inconspicuous color compared to the color, as long as it is viewed from a slightly distant position, it does not impair the sense of unity with the vehicle body outer plate.
[0007]
According to a third aspect of the present invention, in the resin window according to the second aspect, the dots of the base color dot print layer are formed in a shape having an upper limit of 2.5 mm, and the gap between the dots is set to an upper limit of 0.3 mm. It is a configuration that is set, and when such a configuration is adopted, it is possible to obtain continuity of dots when viewed from a position separated by a certain distance, and as a result, You can give a feeling of color by giving a color.
Moreover, when it sets on the above conditions, when forming resin-made windows by in-mold molding, the non-printing part enough to ensure the joint strength of a resin panel and a resin film can be obtained.
[0008]
In this case, as described in claim 4, it is desirable that each dot of the first dot print layer and the second dot print layer is formed in a hexagonal shape. When such a configuration is adopted, the gap between dots can be made constant with respect to all the parts, and the appearance can be improved.
[0009]
According to the sixth aspect of the present invention, it is possible to manufacture a resin window having both a harmony function with the outer color of the vehicle body and a harmony function with the in-car color.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. The resin window according to the present embodiment is applied to a sunroof of an automobile. FIG. 1 is a schematic perspective view showing the sunroof of an automobile equipped with the resin window, and FIG. 2 is a schematic perspective view of the resin window. FIG. 3 is a drawing showing a cross-sectional structure of a resin window.
[0011]
As shown in FIG. 3, the resin window 1 is formed in a plate shape having a three-layer structure including a hard panel body 2 and two resin films 3 and 4 bonded to both surfaces of the panel body 2. As shown in FIG. 1, it is mounted so as to close an opening formed in the roof 15 of the automobile, and as a whole, it is formed in a gently curved shape corresponding to the outer surface shape of the roof 15.
The panel body 2 and the resin films 3 and 4 are both formed of a transparent material such as polycarbonate resin or acrylic resin, and the hard coat layer 5 for preventing scratches is formed on the surface side of the resin films 3 and 4, respectively. , 6 are given. In the following description, the resin film 3 on the outside of the vehicle is referred to as an outside film, and the resin film 4 on the inside of the vehicle is referred to as an in-vehicle film.
[0012]
On the inner surface side of the exterior film 3, that is, on the joint surface side with the panel body 2, a double printed layer of the outer color printing layer 7 and the base color printing layer 8 is provided. Hereinafter, the configuration of these print layers will be described with reference to FIGS.
As shown in FIG. 4, the outer plate color printing layer 7 and the base color printing layer 8 are provided leaving a non-printing portion 11 having a constant width with respect to the entire circumference of the outer film 3.
The outer plate color printing layer 7 is composed of an outer plate color dot printing layer 7a similar in color to the outer plate color of the vehicle body. The outer plate color dot printing layer 7a excludes the non-printing portion 11 on the outer periphery of the vehicle outer film 3. It is given over the entire surface.
[0013]
On the other hand, the base color printing layer 8 is constituted by a base color solid printing layer 8a having a hue corresponding to the in-car color on the entire outer periphery, and the entire area inside the base color solid printing layer 8a is the base color solid printing layer. The base color dot printing layer 8b has the same color as 8a.
Note that the base color solid print layer 8a functions as a so-called blackout that hides the attachment portion to the roof panel from the outside of the vehicle when the resin window 1 is mounted.
[0014]
FIG. 5 shows the planar shape and size of the dots 9 (hereinafter referred to as outer color dots) of the outer color dot printing layer 7a and the dots 10 (hereinafter referred to as base color dots) of the base color dot printing layer 8b. is there. As shown in the figure, in the present embodiment, the base color dot 10 is formed in a regular hexagon circumscribing a circle having a diameter d of 1.8 mm to 2.5 mm, and a gap c between adjacent base color dots 10, That is, the non-printing portion 12 is set to 0.3 mm, and the area occupation ratio of all the base color dots 10 is set to about 80% of the base color dot print layer area. Accordingly, the area occupation ratio of the gap c between the base color dots 10 which are the non-printing portions 12 is about 20% of the base color dot print layer area.
On the other hand, the outer plate color dot 9 is a small regular hexagon that fits in the base color dot 10, specifically, the interval c 1 between each side of the base color dot 10 and each side of the outer plate color dot 9 is 0. The area occupation ratio of all the outer plate color dots 9 is set to about 25% of the outer plate color dot printing layer area.
[0015]
The resin window 1 configured as described above is manufactured by in-mold molding. That is, although not shown in the drawings, in the upper mold and the lower mold of the injection mold, the vehicle exterior film 3 subjected to the hard coat treatment and printing as described above and the vehicle interior film 4 subjected to the hard coat treatment. Are set so that the hard coat treated surface is on the outside (molding surface side). Subsequently, after the mold is clamped, the molten resin material is filled into the mold. And the resin-made window 1 of a desired shape can be obtained by removing a metal mold | die after cooling of resin.
During the above-described in-mold molding, the molten resin material is welded and joined to the film 3 outside the vehicle through the non-printing portion 12 formed by the gap c between the non-printing portion 11 and the base color dot 10 on the outer periphery of the film. . Thus, the vehicle exterior film 3 and the molten resin, and thus the panel body 2 are joined with an area of about 20% of the film area.
On the other hand, the vehicle interior film 4 is bonded to the substantially entire surface by melting resin.
[0016]
According to the resin window configured as described above, the outer panel color printing layer 7 having the same color as the outer panel color can be seen from the outside of the vehicle, and the color harmony between the roof 15 and the resin window 1 is achieved. As shown, the roof 15 and the resin window 1 can have a sense of unity, and the appearance can be improved. On the other hand, the base color printing layer 8 can be seen from the inside of the vehicle, so that the colors of the interior color and the resin window 1 are harmonized, and a calm atmosphere can be produced.
[0017]
In the present embodiment, since the outer plate color dots 9 are formed in a size that is slightly smaller than the base color dots 10, the positional deviation between the dots 9 and 10 during printing can be absorbed. Therefore, when the sizes of both the dots 9 and 10 are set to be the same, it is difficult to manage the positional accuracy during printing. However, as in the present embodiment, the base is in anticipation of a certain amount of positional deviation. By setting the outer color dots 9 to be smaller than the color dots 10, the management of positional accuracy can be facilitated.
If only the positional deviation is considered, it is sufficient that either one of the outer plate color dot 9 and the base color dot 10 is large. However, it is not preferable that the outer panel color outside the vehicle is visible from the inside of the vehicle. By forming the base color dots 10 on the inner side of the vehicle smaller than the outer panel color dots 9 on the outer side of the vehicle, the outer panel color can be completely eliminated from the vehicle interior. Adopting an invisible configuration is important in securing a suitable in-vehicle atmosphere.
[0018]
Further, in the present embodiment, the outer plate color dot 9 is set to a size that is slightly smaller than the base color dot 10, particularly the gap between the sides of both the dots 9 and 10 is set to 0.3 mm. When viewed from outside the vehicle, as long as it is viewed at a close distance, even if the base color dots 10 are seen around the outer plate color dots 9, the continuity between the outer plate color dots 9 can be seen when viewed from a certain distance. Can be obtained.
Further, in many cases, an inconspicuous color (for example, gray) is employed in the interior of an automobile, which is lighter than the outer plate color. Therefore, as long as it is viewed from a position slightly away from the resin window 1 outside the vehicle, the phenomenon that the outer plate color dots 9 “float” in units of dots can be suppressed.
For this reason, according to the present embodiment, it is possible to produce color and give one continuous surface feeling, and it is made of resin that has a sufficient unity feeling with respect to the outer plate color of the roof 15. A window 1 can be provided.
[0019]
In the present embodiment, the outer plate color dots 9 and the base color dots 10 are formed in regular hexagonal shapes, so that the gaps c between these dots can be made constant for all parts. This is because the size of the gap c changes and the dots appear to be raised, or the gap c is given directionality, that is, the gaps appear to be continuous, so that the gap is more conspicuous than the triangle or square. It is possible to improve the appearance.
Further, according to the present embodiment, the area occupation ratio of the gap c between the base color dots 10 which are the non-printing portions 12 is set to about 20% of the base color dot print layer area. When the resin window 1 is formed by in-mold molding, it is possible to suppress the light transmittance while securing the bonding strength between the panel body 2 and the vehicle exterior film 3. In addition, since the non-printing part 11 is provided in the outer peripheral terminal of the film 3 outside a vehicle, and it welds to the panel main body 2 through this non-printing part 11, the twist of a film terminal part is prevented.
[0020]
Further, the outer peripheral portion of the exterior film 3 is constituted by an outer plate color dot print layer 7a and a base color solid print layer 8a, whereby an attachment site for the opening portion of the roof 15 of the resin window 1 is provided from the outside of the vehicle. Can be obscured. Further, if the resin window 1 has a structure in which the outer peripheral edge portion is attached to the opening peripheral edge portion of the roof 15 via a urethane adhesive, the adhesive is shielded from direct sunlight and the deterioration of the adhesive is delayed. can do.
[0021]
In addition, this invention is not limited to said embodiment, It can change suitably within the range which does not deviate from the summary.
For example, the shapes of the outer color dots 9 and the base color dots 10 may be changed to polygons other than hexagons or circles if the gaps between the dots need not be constant. Further, if the problem of misalignment during printing is solved, the dot sizes of the outer color dot print layer 7a and the base color dot print layer 8b may be the same. Moreover, although demonstrated as a case where the resin-made windows 1 are applied to a sunroof, you may apply to other places like a quarter window. In addition, the in-vehicle film 4 may be omitted.
[0022]
In the above embodiment, the shape of the outer plate color dots 9 and the base color dots 10 is a regular hexagon. However, in order to satisfy the condition that the gap is constant or the direction in which the gap appears to be continuous is eliminated. Need not be a regular hexagon. For example, as shown in FIG. 6, it is possible to obtain the same effect other than the regular hexagon.
Moreover, in the said embodiment, although it has the structure where a panel main body is directly joined to a base color printing layer, it is good also as a structure which arrange | positions a binder layer (adhesive layer) in the meantime.
Further, in the above embodiment, the outer plate color dots 9 and the base color dots 10 are formed over the entire inner surface. However, by printing the outer plate color dots 9 at arbitrary positions, characters and patterns that are visible only from outside the vehicle are expressed. Is possible. The same applies to the base color dots 10, and in this case, it is possible to express characters and patterns that are visible only from the inside of the vehicle. In addition, if such a portion having a different thickness is arranged on the surface of the normal panel, it will be caught during cleaning and the printed layer will be easily damaged. However, in this structure, the printed layer is enclosed in the resin. Such a problem does not occur.
In the present embodiment, the resin films 3 and 4 are referred to for explanation, but depending on the thickness, they may be called sheets. And in this invention, since it does not specify the thickness of a film, it is natural to include the thing of the thickness called a sheet | seat.
[0023]
