Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure for a door glass run of an automobile door.

[0002]

2. Description of the Related Art As shown in FIG. 1, a door frame 2 of an automobile door 1 guides the up and down movement of a door glass 3 along its inner circumference and, when the door glass 3 is closed, its outer circumference. A door glass run (hereinafter referred to as a glass run) 6 that seals the
issue).

As the mounting structure, a channel member having a U-shaped cross section, which is shallower than the door frame, is fitted and fixed to the opening side of the door frame having a U-shaped cross section to form a closed cross section between the bottom surfaces of the two. A structure in which a glass run is fitted from the opening side of the member is used.

In this structure, the area of the closed cross section of the door frame is small for its size, which is disadvantageous in terms of rigidity of the door frame, and the door frame and the channel member must be welded.

On the other hand, as shown in FIG. 5 (cross section taken along the line AA in FIG. 1), the door frame 2 having an L-shaped cross section is separated from the door frame 2 by an L-shaped cross section. Door glass run holding member (hereinafter referred to as glass run holding member)
There is a structure in which a channel 4 having a U-shaped cross section is formed by the member 4 and the door frame 2 by screwing and fixing 4 and a glass run 6 is fitted into the channel 5.

In this structure, the glass run holding member 4 is
The side wall 41 serves as a door molding along the vertical frame portion 2A of the door frame 2, but the inner circumference of the upper end corner portion C of the vertical frame portion 2A is not a right angle, and as shown in FIG. In the case of forming an arc having a large radius, the glass run holding member 4 which is designed to form a door molding in accordance with the arc must also be formed in an arc shape which is continuously connected to the horizontal frame portion, which is a structural limitation.

[0007]

DISCLOSURE OF THE INVENTION The present invention provides a glass run mounting structure in which the rigidity of the door frame is ensured and the glass run holding member is provided in the minimum necessary range. It was made as an issue.

[0008]

According to the present invention, as shown in FIG. 2, an inner peripheral surface of a door frame 2 is formed in an L-shaped cross section by a flat portion 210 and a flange 23, and the door frame 2 has a vertical frame. A glass run holding member 4 having a side wall 41 facing the flange 23 on the inner peripheral surface of the portion 2A and a channel portion 5 having a U-shaped cross section is provided on the inner peripheral surface, while being attached to the vertical frame portion 2A. A groove 63 extending vertically is formed in the outer wall 62 of the base portion 61 of the glass run 6, and the base portion 61 is fitted into the channel portion 5, and
The side wall 41 of the glass run holding member 4 is connected to the outer side wall 62.
It has a structure to be inserted into the groove 63.

[0009]

In the present invention, the side wall 41 of the glass run holding member 4 is used.
The side wall 41 does not appear on the outer surface of the glass run 6 because of the structure in which it is inserted into the groove 63 of the outer wall 62 of the glass run 6. Therefore, the glass run holding member 4 may be provided only on the linear portion of the vertical frame portion 2A of the door frame 2.

[0010]

1 and 2, the door frame 2 of an automobile door 1 has a closed cross section formed by an outer panel 21 and an inner panel 22, and a flange 2 is formed on the inner peripheral side.
3 is protruding. The outer panel 21 is bent at a substantially right angle from the outer surface thereof toward the inside of the vehicle to form a flat surface portion 210, and the flat surface portion 210 and the flange 23 form an inner peripheral surface of the door frame having an L-shaped cross section.

On the plane portion 210, the glass run holding member 4 is fixed to the vertical frame portion 2A of the door frame 2 by a clip 7. The glass run holding member 4 has an L-shaped cross section, and is mounted in series on a straight line portion from immediately below the upper end corner portion C of the vertical frame portion 2A to the lower end. The side wall 41 on the vehicle outer side of the glass run holding member 4 is located slightly inside the outer surface of the door frame 2 and faces the flange 23.
The outer panel 21 and the outer panel 21 form a channel portion 5 having a U-shaped cross section.

On the other hand, the glass run 6 includes an extruded vertical member 6A attached to the vertical frame portion 2A of the door frame 2, and a horizontal member 6B attached to the horizontal frame portion of the door frame 2.
A corner portion 6C is formed by connecting these by molding.
A trim portion 60 having a U-shaped cross section is integrally formed on each of the vertical member 6A and the horizontal member 6B. The base 61 of the vertical member 6A has a U-shaped cross section, and lips 64 sandwiching both sides of the door glass 3 extend from both ends of the opening. The horizontal member 6B is hollow with a base 61a having a U-shaped cross section and a seal wall 61b closing the opening thereof, and the seal wall 61b is pushed up by the upper edge of the door glass 3 when the door glass is closed.

The side wall 62 on the vehicle exterior side of the vertical member 6A has a U-shaped cross section with its tip inverted, and a groove 63 is formed in the center. The vertical portion of the molding corner 6C connected to the vertical member 6A has substantially the same sectional shape as the vertical member 6A. The vertical portion has a groove 63 that extends the groove 63 of the vertical member 6A.
a is formed. The groove 63a extends to the bending start portion of the vertical portion, and the upper end has a bag shape.

The vertical portion of the vertical member 6A of the glass run 6 and the vertical portion of the molding corner portion 6C connected to the vertical member 6A are fitted in the channel portion 5 formed in the vertical frame portion 2A of the door frame 2, and at the same time, the grooves 63, 63a. Glass run holding member 4
The side wall 41 of the
It can be firmly attached to the vertical frame portion 2A by being attached to. The horizontal member 6B of the glass run 6 is held on the horizontal frame portion of the door frame 2 by a trim portion 60 integrated with the horizontal member 6B.

When the door glass 3 is moved up and down, the glass run 6, especially the vertical member 6A thereof receives the sliding resistance of the door glass 3, but is held by the base portion 61 and the trim portion 60 and the outer wall 62 of the base portion 61. There is no deviation in the attachment due to the pressure contact between the side wall 41 and the side wall 41 of the glass run holding member 4 which is press-fitted into the groove 63. Further, since the side wall 41 of the glass run holding member 4 does not appear in the appearance, there is no restriction in design. Therefore, even if the glass run 6 is provided only on the vertical frame portion 2A of the door frame 2 where the holding force is required, the design balance around the door frame 2 is not impaired. Further, the door frame 2 also has a large closed cross-section structure.

FIG. 3 shows a second embodiment, in which the flange 23 of the door frame 2 is provided with a bent extension 231 at the tip on the outer panel 21 side, and a projection 611 protruding from the outer surface of the glass run base 61. To engage with.
This strengthens the retention of the glass run 6 from the door frame 2. The other structure is the same as that of the first embodiment.

FIG. 4 shows a third embodiment in which the glass run holding member 4 has a U-shaped cross section. In this case, the glass run 6 is incorporated into the glass run holding member 4 in advance, and the glass run 6 is held together with the glass run holding member 4.
Can be attached to the door frame 2 with one touch using the clip 7 or the like. The other structure is the same as that of the first embodiment.

[0018]

The glass run mounting structure of the present invention has a simple structure and can minimize the installation of the glass run holding member, contributing to weight reduction, and the shape and dimensions of the glass run holding member. Therefore, the design around the door frame is not restricted.
