Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door sash structure for vehicle doors.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 4, there is a vehicle door d such as an automobile provided with a door sash 2 for guiding and holding a vertically movable door glass 1.

As shown in FIG. 5, this door sash 2 is provided with an inner sash panel portion 3 and an outer sash panel portion 4, and inner edge portions 3a of the sash panel portions 3 and 4 located on the door glass 1 side. The sash member 5 is attached between 4a.

The sash member 5 is formed in a U-shaped cross section with the door glass 1 side opened so that a door glass run (not shown) for slidably holding the door glass 1 is provided on the inner surface 6. ing. Further, the outer edge portion 4b of the outer sash panel portion 4 is formed with a folded portion 4c which is folded back by a hemming process or the like.

The inner sash panel portion 3 is bent from the middle portion thereof toward the outer sash panel portion 4 to form a seat portion 3b. Further, the outer edge portion 3c of the inner sash panel portion 3 is sandwiched between the outer edge portion 4b of the outer sash panel portion 4 and a portion 4d in the vicinity thereof. Further, a retainer 7 having an outward opening for fitting a weather strip (not shown) is attached to the seat portion 3b of the inner sash panel portion 3.

On the other hand, at the tip 4e of the outer edge portion 4b of the outer sash panel portion 4, a sealing agent 8 is provided along the longitudinal direction of the door sash 2 in order to prevent rust from being generated in the tip 4e and the folded portion 4c. It is applied by coating. Further, a sealing agent 9 is applied by coating to the portion P of the retainer 7 that is in contact with the inner sash panel portion 3 in order to ensure water tightness in the vehicle interior.

The sealing agents 8 and 9 are coated with a gel-like bead from the nozzle tip while moving the nozzle tip provided in a sealing agent coating device (not shown) along the longitudinal direction of the door sash 2. It is a cured product.

[0008]

By the way, in the door sash structure of the vehicle door constructed as described above,
Not only is it troublesome to perform the bead application work by the nozzle operation corresponding to the sealing agents 8 and 9, but also the bead made at the first time is scraped off at the time of the second nozzle operation, and the appearance is damaged. The watertightness of the nozzles may be impaired, and in some cases, the beads of the first time and the beads of the second time may be mixed as shown in FIG. 6, so skill is required when operating the nozzle. there were. Moreover, if the first and second beads are mixed together in this way, the weather strip may be improperly attached, so it is necessary to correct the beads with a brush or the like (not shown). It was

The present invention has been made in view of the above circumstances, and the sealing agent can be applied by coating with a single nozzle operation, so that the workability can be improved and the cost of the sealing agent can be reduced. Moreover, it is an object of the present invention to provide a door sash structure for a vehicle door that can improve the appearance of the sealing agent without modifying the bead after coating.

[0010]

In order to achieve this object, the present invention comprises an inner sash panel portion and an outer sash panel portion, and the outer edge portion of the outer sash panel portion extends over substantially the entire width in the longitudinal direction of the door sash. Folding back to the inner sash panel portion side, while sandwiching the outer edge portion of the inner sash panel portion between the outer edge portion of the outer sash panel and a portion in the vicinity thereof,
In a door sash structure for a vehicle door provided on the inner sash panel portion in a state where a retainer for attaching a weather strip is brought into contact with the vicinity of the outer edge portion of the inner sash panel portion, the outer edge of the outer sash panel portion is provided. The gap between the tip of the portion and the portion of the retainer that abuts the inner sash panel portion is set to be narrower than the width of one bead when applying a sealing agent, and the sealing agent is the outer sash panel portion. The gist of the present invention is that one coating is applied over the tip of the outer edge portion and the portion of the retainer that is in contact with the inner sash panel portion.

[0011]

In such a structure, the outer edge of the inner sash panel is sandwiched between the outer edge of the outer sash panel and its vicinity, and after the retainer is attached to the inner sash panel, the longitudinal direction of the door sash is increased. A bead is applied along with and cured, and a sealing agent having a width of one bead is applied by straddling the tip of the outer sash panel portion and the portion of the retainer that is in contact with the inner sash panel portion.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the door sash structure for a vehicle door according to the present invention will be described below with reference to FIGS.

FIG. 1 is an enlarged sectional view taken along the line BB in FIG. 3, FIG. 2 is an enlarged perspective view of a main portion, and FIG. 3 is a side view of the door.

In FIG. 3, a door D for a vehicle such as an automobile has a door sash 12 for guiding and holding a door glass 11 which can be raised and lowered.

As shown in FIGS. 1 and 2, the door sash 12 has an inner sash panel portion 13 and an outer sash panel portion 14, and inner edges of the sash panel portions 13 and 14 located on the door glass 11 side. Parts 13a, 14
The sash member 15 is attached between a.

The sash member 15 is formed in a U-shaped cross-section with the door glass 11 side opened so that a door glass run (not shown) made of rubber or the like can be mounted on the inner surface 16 of the sash member 15. Further, a folded-back portion 14c that is folded back to the inner sash panel portion 13 side is formed on the outer edge portion 14b of the outer sash panel portion 14 by a hemming process or the like.

The inner sash panel portion 13 is bent toward the outer sash panel portion 14 from a midway portion thereof, and a seat portion 13b is set. Further, the outer edge portion 13c of the inner sash panel portion 13 is sandwiched between the outer edge portion 14b of the outer sash panel portion 14 including the folded portion 14c and a portion 14d in the vicinity thereof. Further, the seat portion 13b of the inner sash panel portion 13 is provided with a retainer 17 which is opened to the outside, and the retainer 17 is provided with a vehicle door D.
In the closed state, a weather strip 18 for contacting with a peripheral edge of an opening / closing door opening formed in a vehicle body (not shown) for ensuring airtightness / watertightness in a room is fitted.
