  However, a gap is easily generated between the metal door sash and the synthetic resin glass run, and rainwater may enter. In addition, the door sash has a particularly complicated cross-sectional shape, is difficult to manufacture by either roll forming or extrusion, and is difficult to assemble with a separately manufactured glass run. Furthermore, the glass run may fall off the door sash due to long-term use. The door sash often holds a weather strip in addition to the glass run, and there is a similar problem between the door sash and the weather strip.

  It is an object of the present invention to obtain a door sash frame structure that is excellent in binding and assembling properties between a door sash and a glass run and that does not allow rainwater to enter between them for a long period of time.

  According to the present invention, if a door sash, which has conventionally been technically known to be formed from a metal material, is composed of a synthetic resin material, it is possible to increase the integrity of the glass run made of a different synthetic resin material, and to form the door sash. This is based on the viewpoint that the performance and assemblability can be dramatically improved.

The present invention relates to a vehicle door sash frame structure having a door sash that forms a window opening of a vehicle door, a glass run of a window glass guided by the door sash, and a weather strip supported by the door sash. The door sash, the glass run, and the weather strip are each made of a synthetic resin material and are integrally formed by three-color extrusion molding, and the design surface located outside the door sash is further colored resin It is characterized in that either one of the material and the metal material is coextruded .

  In another aspect, the present invention is a vehicle door having the frame structure of any of the above vehicle door sashes.

  Furthermore, in another aspect, it is a vehicle which has the above vehicle door.

In the frame structure of the vehicle door sash of the present invention, the door sash, the glass run, and the weather strip are each made of a synthetic resin material, and are integrally formed by three-color extrusion molding, and are further positioned outside the door sash. Since either one of colored resin material or metal material is co-extruded on the design surface, door sash, glass run and weatherstrip, and also the decorative material on the design surface, formability, integrity, assembly Excellent in properties. In addition, the possibility of integrating the glass run, weatherstrip, design surface, and belt molding resin is expanded by converting the door sash into a resin. Can also be obtained.

  FIG. 1 shows a side shape of a passenger car to which a frame structure of a vehicle door sash according to the present invention is applied. A vehicle door 10 that opens and closes a door opening (body opening) A of a vehicle body B includes a door sash (window frame) 13 that forms a window opening 12 in an upper portion of a door body (inner panel and outer panel) 11.

  The door sash 13 is made of a synthetic resin material, and is a bent upper sash portion 13A that receives the upper edge of the window glass W, and a vertical column sash that receives the vertical edge of the window glass W along the center pillar 16 of the vehicle body B. Part 13B. Below the upper sash portion 13A and the upright column sash portion 13B, there are door fixing portions 13A 'and 13B' that extend into the door body 11 and are fixed to the door body 11.

  The door sash 13 has a design portion 21 exposed on the outer surface of the vehicle, a vehicle width portion 22 extending from the intermediate portion in the width direction of the design portion 21 to the vehicle inner side, as shown in the cross-sectional shapes of FIGS. The vehicle width portion 22 has a thick strength portion 23 formed thick at the inner end portion thereof. A space 24 having a U-shaped cross section is formed between the design portion 21, the vehicle width portion 22, and the thick wall strength portion 23, and a glass run 30 made of a synthetic resin material is integrated in the U-shaped space 24. It is molded into. The glass run 30 itself is a member generally used in a conventional product in which the door sash 13 is made of a metal material, and various shapes and materials are well known. However, in the conventional door sash made of a metal material, a special cross-sectional shape is required to hold the glass run 30, but when the door sash 13 and the glass run 30 both made of a synthetic resin material are integrally molded, Are firmly joined to each other, so that a special shape (prevention portion, dovetail groove, etc.) for holding the glass run 30 on the door sash 13 is unnecessary, and even if it is formed as a simple U-shaped space 24, it can be used for a long time. There is no risk of falling off.

  The door sash 13 is integrally formed with a weather strip 31 in an L-shaped space 25 formed on the opposite side of the U-shaped space 24 by the design portion 21 and the vehicle width portion 22. As with the glass run 30, the weather strip 31 itself is a member having various shapes and materials. The weather strip 31 can be formed integrally with the door sash 13 in the same manner as the glass run 30. When the door sash 13 and the weather strip 31 made of a synthetic resin material are integrally formed, the two are firmly joined to each other. Is not necessary, and even if it is formed as a simple L-shaped space 24, there is no risk of dropping out over a long period of time. In FIG. 2, another weather strip 32 is mounted on the vehicle body B (center pillar 16) side.

  The door sash 13, the glass run 30 and the weather strip 31 can be simultaneously molded by three-color molding and, after molding, can be bent into the upper sash portion 13A and the upright column sash portion 13B. At this time, the glass run 30 and the weather strip 31 formed integrally with the upper sash portion 13A and the glass run 30 and the weather strip 31 formed integrally with the upright sash portion have the same cross-sectional shape, respectively, or variable extrusion. It is also possible to gradually change the width and the like of the design portion 21 using the technique, particularly with respect to the upright column sash portion 13B. Further, the upper sash portion 13A having the glass run 30 and the weather strip 31 and the upright pillar sash portion 13B having another glass run 30 and the weather strip 31 may be formed as separate bodies and joined later. The glass run 30 and weather strip 31 on the upper sash portion 13A side and the glass run 30 and weather strip 31 on the upright pillar sash portion 13B side may have different cross-sectional shapes. FIG. 4 shows a shock when the window glass W is closed by separating the bottom wall 30a of the glass run 30 on the upper sash portion 13A side from the bottom wall of the U-shaped space 24 of the upper sash portion 13A to provide cushioning. This is an example of a shape that is reduced.

  The weather strip 31 can be attached to the door sash 13 and the glass run 30 formed in two colors in a later process. FIG. 5 shows this aspect, and the door sash 13 is formed with a dovetail groove 25 </ b> A for holding the weather strip 31 later, instead of the L-shaped space 25 of FIGS. 2 and 3. In this embodiment, the weather strip 31 is mounted later on the dovetail groove 25A of the door sash 13 after molding.

An example of a combination of different synthetic resin materials when the door sash 13 and the glass run 30 (and the weather strip 31) are two-color molded (three-color molded) is as follows.
Material of door sash 13; PP, ABS
Glass run 30 material; TPO, EPDM
Weather strip 31 material; EPDM

  As described above, the door sash frame structure according to the present invention can be further technically developed because the door sash 13 and the glass run 30 (and the weather strip 31) are both made of a synthetic resin material and integrally molded. is there.

  FIG. 6 shows an embodiment in which the colored resin material 26 is two-color molded on the outer surface of the design portion 21 of the door sash 13. In a conventional door sash made of a metal material, a colored resin tape (black tape) is bonded after joining the vertical column sash and the upper sash. However, when the door sash 13 is made into a resin, the colored resin material 26 Therefore, this colored resin tape can be substituted, and the number of man-hours can be greatly reduced.

  FIG. 7 shows an embodiment in which a design member 27 made of a metal material is simultaneously extruded or insert-molded on the outer surface of the design portion 21 of the door sash 13. The metal design member 27 is made of, for example, a stainless material, and is conventionally rivet-bonded to a door sash in a conventional product. In the present embodiment in which the door sash 13 is made of resin, the metal design member 27 can be subjected to simultaneous extrusion molding (composite molding) or insert molding, and man-hours can be reduced. Moreover, there is no fear of dropping off.

  The configuration of FIG. 7 can be applied particularly to an aspect in which an external part called garnish is mounted on the outer surface of the design portion 21 of the upright pillar sash portion 13B.
