Description

  The present invention relates to a vehicle resin window, and more particularly to a vehicle resin window including a transparent or translucent hard resin base material having a two-dimensional or three-dimensional design shape.

  Conventionally, as shown in FIGS. 5 to 6, a part of a window of a vehicle such as the automobile 101 (for example, a triangular window of a front door) is a resin instead of a glass window in order to reduce the weight and increase the degree of freedom of shape. A window 110 may be used. As shown in FIGS. 7 to 8, the resin window 110 has a two-dimensional design shape similar to the glass window, and is composed of a transparent or translucent hard resin base material 120. The base material 120 is integrally molded (for example, injection molding) from the base material main body 122 and an edge body 124 that is formed on the periphery of the base material main body 122 and forms an attachment portion facing the body of the automobile 101. Has been.

  On the back side (inner side) of the design of the edge body 124, screen printing is performed by a screen printing apparatus (not shown) (in FIG. 7, the shaded portion is shown in FIG. The printing unit 130, which is an applied portion, is shown). Accordingly, when the resin window 110 is attached to the body of the automobile 101 via the clip 126 or an adhesive (not shown), the clip 126 or the adhesive is printed even when the attached resin window 110 is viewed from the design side. The part 130 can be blindfolded. Therefore, it is possible to improve the appearance of the resin window 110 in a state of being attached to the body of the automobile 101.

As prior art document information relating to the invention of this application, for example, a screen printing apparatus disclosed in Patent Document 1 is known.

  However, in the above-described conventional technology, the curvature R1 (hereinafter referred to as “first curvature R1”) that forms the design shape of the base body 122 and the curvature R3 (hereinafter referred to as “third” that forms the design shape of the edge body 124). Is the same (refer to FIG. 8). Therefore, when these curvatures R1 and R3 are larger than the curvature R2 that can be screen-printed (hereinafter referred to as “second curvature R2”), the net (not shown) of the screen printing apparatus cannot follow the design back surface of the edge 124. was there. Therefore, a problem (for example, a problem that a parting line for printing is shifted) may occur in the screen printing (printed printing unit 130) applied to the back side of the design of the edge body 124.

  The present invention is intended to solve such a problem. The purpose of the present invention is to form an attachment member formed on the periphery of the base body even when the curvature of the design shape of the base body is larger than the curvature capable of screen printing. It is providing the resin window of a vehicle which does not produce a malfunction in the screen printing performed on the design back surface side of the edge which comprises the attachment part which opposes.

The present invention is for achieving the above object, and is configured as follows.
The invention described in claim 1 is a resin window provided with a transparent or translucent hard resin base material having a two-dimensional or three-dimensional design shape. The base material is integrally composed of a base material main body and an edge formed for body assembly on the periphery of the base material main body. A printing portion is provided by screen printing on the back side of the design of the edge body. The curvature of the back side of the design of the edge body to which the printing unit is applied corresponds to the curvature that can be screen-printed.

  According to the first aspect of the present invention, the curvature (the first curvature R1 in each embodiment) forming the design shape in the base body is larger than the curvature (second curvature R2 in each embodiment) that can be screen-printed. Even in this case, since the curvature (the third curvature R3 in each embodiment) forming the design shape of the edge corresponds to the curvature (second curvature R2 in each embodiment) that can be screen-printed, the edge The screen printing performed on the back side of the design (in each embodiment, the printed printing unit 30) does not cause a problem (for example, a problem that a parting line for printing is shifted).

  Moreover, invention of Claim 2 is the resin window of the vehicle of Claim 1, Comprising: The thickness of an edge is formed thinner than the thickness of a base-material main body.

  According to the invention of claim 2, it is possible to make it difficult to cause sink marks and warpage in the edge of the finished resin window (after cooling).

  The invention according to claim 3 is the resin window of the vehicle according to any one of claims 1 to 2, wherein the boundary between the edge body and the substrate body on the design back side of the substrate is chamfered. It has been subjected.

  According to invention of Claim 3, the boundary of the edge body and base-material main body in the design back surface side (inner surface side) of a base material can be made smooth. Therefore, when screen printing is performed on the design back surface side (inner surface side) of the edge by, for example, a screen printing device, the net of the screen printing device can be prevented from being caught on the boundary between the edge and the substrate body. As a result, the net of the screen printing apparatus can be suppressed.

FIG. 6 is a cross-sectional view of a resin window according to Example 3. FIG. It is a figure explaining the modification of Example 2. FIG. It is a perspective view of the motor vehicle which applied the resin window which concerns on a prior art. In FIG. 5, it is the perspective view which decomposed | disassembled the resin window. FIG. 6 is an enlarged view of a resin window on the right side of FIG. 5. It is sectional drawing of the resin window of FIG.

Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.
Example 1
First, Embodiment 1 of the present invention will be described with reference to FIG. First, the resin window 10 of Example 1 will be described. The resin window 10 has a two-dimensional design shape similar to the resin window 110 described in the prior art, and includes a transparent or translucent hard resin base material 20.

  Similar to the base material 120 described in the prior art, the base material 20 forms a base material body 22 and an attachment portion that is formed on the periphery of the base material body 22 and faces the body of an automobile (not shown). The edge body 24 is integrally molded (for example, injection molding). This body corresponds to the “mounting member” recited in the claims. The thickness of the edge body 24 is formed thinner than the thickness of the base body 22.

  The design shape of the base body 22 has the same curvature as the base body 122 described in the prior art (first curvature R1). The first curvature R <b> 1 is large such that the net (not shown) of the screen printing apparatus cannot follow the design back surface (inner surface) of the base body 22. On the other hand, the design shape of the edge body 24 has the same curvature as the edge body 124 described in the prior art (third curvature R3).

  The third curvature R3 is small so that the net of the screen printing apparatus can follow the design back surface (inner surface) of the edge body 24. That is, the third curvature R3 corresponds to the curvature R2 (second curvature R2) that can be screen printed. Therefore, similarly to the design back side (inner surface side) of the edge 124 described in the prior art, screen printing is performed on the design back side (inner side) of the edge body 24 by a screen printing apparatus (not shown). (For example, the black printing unit 30 is printed).

  Thus, as in the prior art, when the resin window 10 is attached to the body of an automobile via a clip or an adhesive (both not shown), even when the attached resin window 10 is viewed from the design side. Or the adhesive can be blinded by the printing unit 30. Therefore, like the prior art, the appearance of the resin window 10 in a state of being attached to the body of the automobile can be improved. The resin window 10 is configured in this way.

  The resin window 10 according to the first embodiment of the present invention is configured as described above. According to this configuration, the design shape of the base body 22 is the first curvature R1. The first curvature R1 is large such that the net of the screen printing apparatus cannot follow the design back surface (inner surface) of the base body 22. On the other hand, the design shape of the edge body 24 is the third curvature R3. The third curvature R3 is small so that the net of the screen printing apparatus can follow the design back surface (inner surface) of the edge body 24. That is, the third curvature R3 corresponds to the curvature R2 (second curvature R2) that can be screen printed. Therefore, even when the curvature R1 (first curvature R1) forming the design shape in the base body 22 is larger than the curvature R2 (second curvature R2) that can be screen-printed, the curvature R3 (designing the edge body 24). Since the third curvature R3) corresponds to the curvature R2 (second curvature R2) that can be screen-printed, there is a problem with the screen printing (printed printing unit 30) applied to the design back side of the edge 24 ( For example, there is no problem that a parting line for printing is shifted.

  Moreover, according to this structure, the thickness of the edge body 24 is formed thinner than the thickness of the base body 22. Therefore, it is possible to make it difficult to cause sink marks and warpage in the edge body 24 of the finished resin window 10 (after cooling).

(Example 2)
Next, Embodiment 2 of the present invention will be described with reference to FIG. The resin window 12 of the second embodiment is a form in which the edge body 24 is strengthened as compared with the resin window 10 of the first embodiment already described. In the following description, members having the same or equivalent configuration as those described in the first embodiment are denoted by the same reference numerals in the drawings, and redundant description is omitted. The same applies to Example 3 described later.

  The resin window 12 of the second embodiment has a two-dimensional design shape similar to the resin window 10 described in the first embodiment, and is composed of a transparent or translucent hard resin base material 20. Yes. Similar to the base material 20 described in the first embodiment, the base material 20 has a base body 22 and mounting portions that are formed on the periphery of the base body 22 and face the body of an automobile (not shown). It is integrally molded (for example, injection molding) from the formed edge body 24. The thickness of the edge body 24 is thicker than the thickness of the base body 22.

  In addition, the boundary between the edge body 24 and the base material body 22 on the design back side (inner surface side) of the base material 20 is chamfered. This chamfered portion is the chamfered portion 40 in FIG. The resin window 12 is configured in this way.

  The resin window 12 according to the second embodiment of the present invention is configured as described above. According to this configuration, similarly to the resin window 10 described in the first embodiment, the curvature R1 (first curvature R1) forming the design shape in the base body 22 can be screen-printed curvature R2 (second curvature R2). The curvature R3 (third curvature R3) that forms the design shape of the edge 24 corresponds to the curvature R2 (second curvature R2) that can be screen-printed even when the edge 24 is larger. The screen printing (printed printing unit 30) applied to the side does not cause a problem (for example, a problem that a parting line for printing is shifted).

  Moreover, according to this structure, the thickness of the edge body 24 is formed thicker than the thickness of the base body 22. Therefore, the edge body 24 can be made strong.

  In addition, according to this configuration, the boundary between the edge body 24 and the substrate main body 22 on the design rear surface side (inner surface side) of the substrate 20 is chamfered (the chamfered portion 40 is formed). Therefore, the boundary between the edge body 24 and the substrate body 22 on the design back side (inner surface side) of the substrate 20 can be made smooth. Therefore, when screen printing is performed on the design rear surface side (inner surface side) of the edge body 24 by the screen printing apparatus, the net of the screen printing apparatus can be prevented from being caught on the boundary between the edge body 24 and the base body 22. As a result, the net of the screen printing apparatus can be suppressed.

(Example 3)
Finally, Example 3 of the present invention will be described with reference to FIG. The resin window 14 according to the third embodiment has a form that can further prevent the screen printing apparatus from breaking the net as compared with the resin window 12 according to the second embodiment described above.

  The resin window 14 of the third embodiment has a two-dimensional design shape similar to the resin window 12 described in the second embodiment, and is composed of a transparent or translucent hard resin base material 20. Yes. Similar to the base material 20 described in the second embodiment, the base material 20 has a base material body 22 and an attachment portion formed on the periphery of the base material body 22 and facing the body of an automobile (not shown). It is integrally molded (for example, injection molding) from the formed edge body 24. The thickness of the edge body 24 is thicker than the thickness of the base body 22.

  In addition, the build-up part 50 is formed along the design back surface (inner surface) of the base material main body 22 from the boundary between the edge body 24 and the base material main body 22 on the design back surface side (inner surface side) of the base material 20. The resin window 14 is configured in this way.

  The resin window 14 according to the third embodiment of the present invention is configured as described above. According to this configuration, similarly to the resin window 12 described in the second embodiment, the curvature R1 (first curvature R1) forming the design shape of the base body 22 can be screen-printed curvature R2 (second curvature R2). The curvature R3 (third curvature R3) that forms the design shape of the edge 24 corresponds to the curvature R2 (second curvature R2) that can be screen-printed even when the edge 24 is larger. The screen printing (printed printing unit 30) applied to the side does not cause a problem (for example, a problem that a parting line for printing is shifted).

  Moreover, according to this structure, the build-up part 50 is along the design back surface (inner surface) of the base material main body 22 from the boundary of the edge body 24 and the base material main body 22 in the design back surface side (inner surface side) of the base material 20. Is formed. Therefore, the boundary between the edge body 24 and the substrate body 22 on the design back side (inner surface side) of the substrate 20 can be made smooth. Therefore, when screen printing is performed on the design rear surface side (inner surface side) of the edge body 24 by the screen printing apparatus, the net of the screen printing apparatus can be prevented from being caught on the boundary between the edge body 24 and the base body 22. As a result, the net of the screen printing apparatus can be further suppressed.

  The contents described above are only related to one embodiment of the present invention, and do not mean that the present invention is limited to the above contents.

  In each Example, the form which the resin windows 10, 12, and 14 have a two-dimensional design shape was demonstrated. However, the present invention is not limited to this, and the resin windows 10, 12, and 14 may have a three-dimensional design shape.

  Moreover, in each Example, the design shape of the base-material main body 22 demonstrated the form used as 1st curvature R1. However, the present invention is not limited to this, and the design shape of the base body 22 may be in the form of the second curvature R2. In that case, at least the curvature R3 (third curvature R3) forming the design shape of the edge body 24 may correspond to the curvature R2 (second curvature R2) that can be screen-printed.

  Moreover, in each Example, the form whose vehicle was a motor vehicle was demonstrated. However, the present invention is not limited to this, and the vehicle may be various vehicles.

  As shown in FIG. 4, in Example 2, when screen printing is performed, the spacer 60 may be inserted into the design surface side (inner surface side) of the base body 22. In that case, when screen printing is performed on the design back side (inner surface side) of the edge body 24 by a screen printing apparatus (not shown), the net of the screen printing apparatus is caught on the boundary between the edge body 24 and the base body 22. Can be further prevented. As a result, the net of the screen printing apparatus can be further suppressed.
