Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a glass run used for a press door type door of an automobile.

[0002]

2. Description of the Related Art In a press door type door, a sash portion is formed by joining a door inner panel and a door outer panel, and the sash portion has an inner circumference.
A glass run is installed to seal the edge of the door glass. Both front and rear ends of this glass run enter the inside of the door and are in sliding contact with the front and rear edges of the door glass that moves up and down.

As the glass run, a glass run which is freely bendable and rich in flexibility is generally used. For example, a material obtained by extruding only a rubber material without a core material, or a material having a core material in which a large number of wires arranged so as to be orthogonal to the longitudinal direction of the glass run are knitted with a thread, etc. are used, The both ends of the inside of the door are fitted and attached to the flange of the sash portion, and attached to the separate sash arranged inside the door.

Further, in recent years, a glass run integrally formed with a cored bar having rigidity may be used (see JP-A-2-48222 as a similar technique). In this case, the grass run is preliminarily formed in a substantially U shape along the sash portion, and is fitted to the inner circumference of the sash portion.

[0005]

In the glass run having flexibility like the former, when the glass run is attached to the door, first, the corners of the grass run are fitted to the corners before and after the upper edge of the door, and then, The work procedure is to fit the upper edge part along the upper edge of the door, and finally fit both front and rear ends to the sash inside the door, but for the part below the door waist part, the door inner panel Workability is poor because it is a form that you put your hand through the provided work hole and work by hand. That is, it is difficult to properly attach the flexible glass run to the sash inside the door, which takes time to perform the work, and the fatigue of the worker becomes great.

On the other hand, in the latter glass run having a core and having rigidity, as shown in FIG. 10, first, as shown in FIG. The lower part is inserted into the door 31, and the grass run 33 is positioned between the door inner panel and the door outer panel. Then, the glass run 33 is pushed upward from the state shown in the figure and fitted into the sash portion 34 and the sash inside the door 31. But,
Since the grass run 33 is formed in a predetermined substantially U-shape in advance, it is difficult to properly align the corner portions 33a and 33b with the corner portions 34a and 34b of the door sash portion 34, and the whole is positioned substantially at the same time. Because it had to be done, the work was very difficult.

[0007]

SUMMARY OF THE INVENTION Therefore, according to the present invention, in a glass run for a press door in which a door inner panel and a door outer panel are joined to each other to form a sash portion, a substantially straight front edge is formed along a vertical direction. Part and rear edge are integrally formed with a rigid cored bar, and the upper edge between them is formed to have flexibility, and the lower front edge and the lower rear edge are fixed to the door panel. The feature is that a bracket is provided.

[0008]

In the above construction, one of the front edge portion and the rear edge portion is fixed to the door to correctly position the corner portion, and then the upper edge portion is fitted to the sash portion and the front edge portion or the rear edge portion is Fix the other to the door to complete the installation. In other words, they can be attached while sequentially positioning. The front and rear edges, some of which are located inside the door, have rigidity,
It is fixed to a door panel, for example, a door inner panel via a bracket.

Is a front edge portion 2 having a substantially straight line extending in the up-down direction, a rear edge portion 3 having a substantially straight line extending in the up-down direction, and an upper edge portion 4 having an upper edge of the door. The corner portions 5 and 6 are molded and connected in a substantially U-shape.

2 to 4, the glass run 1 is made by extruding a rubber material, has a substantially U-shaped cross section, and has a door glass (not shown) at its opening. It has seal lips 7 and 8 for sealing the edges.
Further, leg portions 9 and 10 are attached to both side portions, and a pair of flange fitting grooves 11 and 12 are formed by these. Further, with respect to the front edge portion 2 and the rear edge portion 3, a core metal 13 having a rigidity is embedded from the substantially U-shaped cross-section portion to one leg portion 9. That is, the front edge portion 2 and the rear edge portion 3 are formed into a highly rigid rod shape by the core metal 13. A pair of upper and lower brackets 14 are fixed to the lower portion of the front edge portion 2 and the lower portion of the rear edge portion 3 which are inserted into the door. This bracket 14
As shown in FIG. 8, it has a substantially L shape, and the base is grass run 1.
