[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 press door type door of an automobile, and more particularly to a corner structure thereof.

[0002]

2. Description of the Related Art As shown in FIG. 1, a door glass run (hereinafter, referred to as a glass run) 3 is attached to a door frame 2 of a press door type door 1 of an automobile along an inner periphery thereof. . This glass run 3 is a door frame 2
In the corner portion of the extruded body 3, as shown in FIG.
It is constituted by a substantially L-shaped molded part 3C in which the terminal of A and an extruded body 3B attached along the vertical side of the door frame 2 are connected by molding.

The glass run 3 has a substantially U-shaped cross-section, into which an end of a door glass 4 is inserted and which comes into contact with and seals with the end.
5 and 36. A retainer (not shown) having a substantially U-shaped cross section provided on the inner peripheral surface of the door frame 2.
The mounting bases 31 and 34 provided with the engagement ribs that engage with the retainer are fitted and mounted in the retainer.

When the door is a press door type, a flat portion and a flange portion projecting in the inner circumferential direction are formed on the inner peripheral surface of the door frame. When trying to mount a glass run on such a door frame, the actual opening
A glass run having a substantially rectangular cross-section seal portion and a substantially U-shaped cross-section trim portion provided on the side of the seal portion as described in JP-A-2-156522 is prepared. Or a glass run is attached to the above-mentioned flange portion, or a retainer having a substantially U-shaped cross section is attached to the flat portion, and the glass run having a substantially U-shaped cross section is fitted into the retainer as described above. Absent.

The mounting of the glass run using the former trim portion has a disadvantage that the receiving surface of the end portion of the door glass of the seal portion becomes narrower by the thickness of the trim portion, and the use thereof is restricted. Was. Further, in the latter case, although the problem that the receiving surface of the end portion of the door glass becomes narrow does not occur, the end portion of the flange portion is exposed to the inside of the vehicle, and the appearance is deteriorated. For this reason, it has been attempted to form an extended portion by forming the inner side wall of the glass run longer than the outer side wall to hide the end of the flange portion.

[0006]

However, in the corner portion of the door of the press door type, since the above-mentioned flange portion is formed in a curved shape, the amount of extension of the above-mentioned glass run on the inner side wall of the vehicle is also reduced. It grows in proportion to it. For this reason, there is a possibility that deformation such as waving may occur in an extension of the inner wall of the glass run at the corner portion.

Also, at the corner, a gap is formed between the extension and the side surface of the flange, and when the end of the extension abuts on the side of the flange, the extension is fogged.
There was a possibility that the engagement between the engagement protrusion of the glass run and the retainer might be released.

An object of the present invention is to provide a press door type door which can be provided with a good appearance without causing deformation such as waving in an extension of a side wall on the inside of a glass run at a corner portion. Another object of the present invention is to provide a glass run with good assemblability.

[0009]

In order to solve the above problems, the glass run of the present invention is mounted along the inner periphery of a door frame 2 of a press door type door 1 of an automobile and has an upper side of an extruded product. Part 51 and the vertical side part 52 of the extruded product

A substantially rectangular parallelepiped convex portion 60 is formed on the inner side surface of the vehicle 56a in parallel with the longitudinal direction of the upper side portion 51, and a substantially cylindrical support protrusion 70 is formed at the center of the extended portion 56a of the molded portion 53. Is formed.

[0010]

According to the glass run of the present invention, the substantially rectangular parallelepiped convex portion 60 is formed on the inner side surface of the extension portion 56a of the molded portion 53 in parallel with the longitudinal direction of the upper side portion 51.
The rigidity in the direction parallel to the longitudinal direction of the upper side portion 51 is increased, and deformation such as waving is prevented. In addition, since the substantially cylindrical support protrusion 70 is formed at the center of the molded extension portion 56a, it is possible to prevent the extension portion 56a from being fogged due to the gap between the extension portion 56a and the side surface of the flange portion. To stabilize the assembly of the glass run to the retainer.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In order to better understand the present invention, FIG.
Explanation will be made based on FIG. The same parts as those in the conventional example are denoted by the same reference numerals in the illustrated example, and a part of the description is omitted.

As in the prior art, a flat portion 5 and a flange portion 6 protruding in the inner circumferential direction are formed on the inner peripheral surface of the door frame 2 of the door 1 of the automobile press door type. An L-shaped retainer 7 is attached from the vehicle outer side surface of the flange portion 6 to the flat portion 5, and an L-shaped metal molding 8 is fixed to the flat portion 5 portion of the retainer 7 with a rivet 9. The retainer 7 and the metal molding 8 form a mounting recess 10 having a substantially U-shaped cross section, and the glass run 50 is fitted and mounted in the mounting recess 10.

The end of the flange 6 is covered with a resin frame garnish 11 as shown in FIG. In FIG. 5, reference numeral 12 denotes a sponge rubber weather strip, 13 denotes a roof weather strip attached to the roof side, and 14 denotes a door opening trim attached to a peripheral edge of the door opening of the body.

As in the prior art, the glass run 50 of this embodiment includes an upper side 51 of an extruded body attached along the upper side of the door frame 2 and an extruder mounted along the vertical side of the door frame 2. An extended portion 56 comprising a vertical side portion 52 of the molded body and a molded portion 53 connecting the upper side portion 51 and the vertical side portion 52 at a corner portion, wherein the inner side wall 54 is formed longer than the outer side wall 55. , 56a. The engagement rib 54a projecting from the vehicle interior side wall 54 to the vehicle interior is engaged with the retainer 7, and the engagement rib 55a projecting from the vehicle exterior side wall 55 to the vehicle exterior is engaged with the metal molding 8, respectively. 10 is mounted.

A substantially rectangular parallelepiped convex portion 60 is formed on the inner side surface of the extension portion 56a of the molded portion 53 in parallel with the longitudinal direction of the upper side portion 51. In addition, this extension 5
A substantially cylindrical support protrusion 70 is formed at the center of 6a. These projections 60 and support projections 70 are formed simultaneously with and integrally with the extension 56a during the molding.

The substantially rectangular parallelepiped convex portion 60 is formed in parallel with the longitudinal direction of the upper side portion 51, that is, in the vicinity of the engaging rib 54a and in parallel with the engaging rib 54a. This is to increase the rigidity of the upper side portion 51 in the direction parallel to the longitudinal direction of the portion 56a and to stabilize the engagement of the engagement rib 54a. The reason why the substantially cylindrical support protrusion 70 is formed at the center of the extension 56a is to suppress the fogging of the extension 56a caused by the gap between the extension 56a and the side surface of the flange 6, and to reduce the glass. This is for stabilizing the assembly of the run 50 to the retainer 7.

[0017]

As described in detail above, in the door glass run of the present invention, a substantially rectangular parallelepiped convex portion is formed on the inner side surface of the extended portion of the molded portion in parallel with the longitudinal direction of the upper side portion. The rigidity in the direction parallel to the longitudinal direction of the upper side of the portion can be increased, and deformation such as waving can be prevented, so that the appearance can be improved.

In addition, since the substantially cylindrical support projection is formed at the center of the extension of the molding, it is possible to prevent the extension from being fogged by the gap between the extension and the side surface of the flange. As a result, assembling of the glass run to the retainer can be stabilized, so that the assembling property is improved.
