DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door glass run mounted on a door frame of an automobile door.

[0002]

2. Description of the Related Art As shown in FIG. 3, an inner periphery of a door frame 2 of an automobile door 1 is guided along the inner periphery of the door frame 2 to move up and down. Door glass run 6 that seals between 2
Is installed.

As shown in FIG. 4, in a door glass run (hereinafter, referred to as a glass run) 6, seal lips 63 extend in opposite directions from the tips of left and right side walls 62 of a main body having a U-shaped cross section. The structure in which the molding lip 64 extends from the tip along the outer surface of the side wall 62 is widely used.

On the other hand, an inner plate 2
A channel member 4 having a U-shaped cross section is provided between the glass member 6 and the outer plate 22.
The inner wall of the inner plate 21 and the outer plate 22 of the door frame 2 which overlaps with the channel member 4 is overlapped with the side wall 62 and the molding lip 64 while the bottom wall 61 is fitted into contact with the bottom surface of the channel member 4. It is attached to the door frame 2 so as to sandwich the portion.

Recently, for the purpose of reducing the weight of a door, a door frame without a channel member (a channelless door frame) has been used depending on a vehicle model. However, if there is no channel member that receives the bottom wall of the glass run from above, when the door glass rises and closes, the upper edge of the door glass pushes up and deforms the bottom wall of the glass run, so that the rising end position of the door glass is accurate. It is not decided. In addition, since there is nothing to restrict the position of the bottom wall when the main body is inserted into the door frame, the bottom wall may be deformed into a shape obliquely inclined with respect to the side wall, and may be attached as it is. . Further, if the relative positions of the main body and the door glass entering and exiting the main body vary from side to side, the forces acting on the left and right side walls become unbalanced, and the sectional shape of the main body gradually changes.

Therefore, in the channelless frame, a stopper member is provided at a predetermined position in the frame, for example, at the center of the upper horizontal portion of the door frame and in the vicinity of the upper rear corner, to receive the bottom wall of the glass run from above. By providing the stopper member, the position of the rising end of the door glass is regulated.

[0007] However, the stopper member is provided in only a part of the glass run, and in the other part of the glass run, the main body may be deformed and the sealing performance may be deteriorated.

[0008]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a glass run that does not cause a cross-sectional deformation in the main body even when it is mounted on a channelless frame.

[0009]

The glass run of the present invention comprises:
The door frame is formed by sandwiching the inner peripheral ends of the inner plate and the outer plate of the door frame between left and right side walls of the main body having a U-shaped cross section and molding lips that extend from the tips of the side walls and extend along the outer surface of the side wall. A glass run attached to the left and right sides of the door glass with seal lips extending from the front ends of the left and right side walls in opposite directions so as to sandwich the periphery of the door glass from the inner and outer surfaces, and the left and right corners where the bottom wall and the side wall of the main body are connected A projection is formed at the corner in a diagonal direction from the inner surface of the bottom wall so as to cross the corner, and a tip is formed so as to be in contact with the inner surface of the side wall facing the corner.

When a force is applied to the main body to change its cross-sectional shape, the projections are kept taut and maintain the angle of the corner, so that the U-shaped cross-sectional shape of the main body does not change.

[0011]

FIG. 1 shows a glass run of the present invention mounted on a door frame (channelless frame) 2 of an automobile door. A glass run 6A is an extruded rubber body, and a bottom wall 61 and a glass run 6A are provided. The main body composed of the left and right side walls 62 has a U-shaped cross section, and seal lips 63 extend from the tips of both side walls 62 in opposing directions. Also, the molding lip 64 is inverted from these tips so as to follow the outer surface of the side wall 62.
Is extending.

The corners of the main body where the bottom wall 61 and the left and right side walls 62 are connected are lightened on the inner surface so that they can be easily bent. The bottom wall 61 has an intermediate portion excluding the corners at both ends, which is thickly formed on the inner surface side in the form of a built-up, and protrudes obliquely from both ends of the thick portion 610 so as to cross the corner and close it. 65 protrudes, and its tip abuts on the inner surface of the side wall 62 facing the tip.

In the glass run 6A, both side walls 62 open in an octagonal shape, the leading ends of both seal lips 63 are separated, and
Is extruded in a cross-sectional shape separated from the inner surface of the side wall 62.

As shown in FIGS. 1 and 2, an automobile door 1
The door frame 2 is a channelless frame in which no channel member is provided between the inner peripheral ends of the inner plate 21 and the outer plate 22. The door frame 2 has two portions, an upper horizontal portion and a portion directly below the rear end corner portion. A stopper member 5 is attached. The stopper member 5 has a cross-sectional shape obtained by bending a strip-shaped metal plate into a shallow hat shape, and has both ends 52 in the longitudinal direction at the inner surface of a portion of the inner plate 21 of the door frame 2 which is substantially horizontal in the door thickness direction.
Are welded, and the bottom 5
Reference numeral 1 denotes a rising end position of the door glass through the thickness of the bottom wall 61 of the glass run. Note that the bent portion of the stopper member 5 is formed with a folding rib 53 for reinforcement, thereby increasing the rigidity of the bent portion.

The glass run 6A is constructed such that the inner peripheral ends of the inner plate 21 and the outer plate 22 of the door frame 2 are inserted between the left and right opposing side walls 62 and the molding lip 64. Is fitted to the door frame 2 by fitting it between the inner peripheral ends of the inner plate 21 and the outer plate 22, and the bottom wall 61 abuts against the bottom surface 51 of the stopper member 5 at the installation site of the stopper member 5. The left and right corners of the attached glass run 6A are substantially perpendicular to each other, and the side walls 62 are parallel to each other, and the tips of the left and right projections 65 are in contact with the inner surface of the side wall 62 opposed thereto.

The glass run 6A is brought close to the opposite direction with the left and right side walls 62 extruded in an open shape sandwiched between fingers.
By making the tips of the left and right protrusions 65 abut against the inner surface of the side wall 62, the main body has a constant U-shaped cross section. In this state, the main body is pushed into the gap between the inner peripheral ends of the inner and outer plates 21 and 22 of the door frame, so that the main body is fitted to the door frame without any cross-sectional deformation.

If the position of the door glass 3 entering and exiting the main body of the glass run 6A varies from side to side, and imbalance occurs in the force acting on the left and right side walls 62, the stopper member 5 is provided.
In the portion where the bottom wall 61 is not pressed, the left and right side walls 62 are displaced up and down with respect to the door frame 2 to try to tilt the bottom wall 61. Since the change is prevented, the main body retains its cross-sectional shape and does not shift with respect to the door frame 2.

[0018]

The main body of the glass run of the present invention has a shape maintaining performance by itself, and is maintained in a constant cross-sectional shape even when the glass run is attached and when the door glass enters and exits. Therefore, the present invention is particularly effective when applied to a channelless frame of an automobile door.
