DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a glass run fitted on a door sash of a vehicle and guiding a sliding door glass moving up and down.

[0002]

2. Description of the Related Art The configuration of a conventional glass run 21 will be described with reference to FIGS. The glass run 21 is fitted on a door sash 23 of a door 22 of the vehicle, and guides a sliding door glass 24 that moves up and down into the groove 2. The groove portion 2 has a substantially U-shaped cross section, and is formed by the vehicle outer side wall portion 3, the bottom wall portion 4, and the vehicle inner side wall portion 5. An outer lip 6 and an inner lip 7 are formed on the inside of the vehicle outer side wall 3 and the outside of the vehicle inner side wall 5, respectively. An outer molding lip 8 is formed on the outside of the vehicle outer side wall 3 and inside the vehicle inner side wall 5. An inboard molding lip 9 is formed. By inserting the flange 25 of the door outer panel between the outer molding lip 8 and the outer wall 3 and simultaneously inserting the flange 26 of the door inner panel between the inner molding lip 9 and the inner wall 5. The glass run 21 is fitted on the door sash 23.

[0003]

However, according to the conventional glass run 21, the flange 2 of the door outer panel is not provided.
In order to prevent the outer molding lip 8 from rising from the flange 25 when the 5 is inserted, the gap L between the outer wall 3 serving as an insertion opening of the flange 25 and the tip of the outer molding lip 8 is reduced. Car exterior wall 3
The outer lip 8 is formed so as to be positioned with respect to the outer lip 8. The smaller the gap L between the vehicle exterior wall portion 3 and the tip of the vehicle exterior molding lip 8 is, the better the appearance is because the floating from the flange 25 of the door outer panel of the vehicle exterior molding lip 8 is prevented. For this reason, when fitting the glass run 21 to the door sash 23 in the vehicle assembling process, the edge of the flange 25 is directly located at the portion of the slight gap L between the outer wall portion 3 and the tip of the outer molding lip 8. It is very difficult to insert it because it is necessary to aim and insert it.
The gap L between the vehicle and the vehicle exterior wall 3 has to be widened and inserted by hand, and assembling to the vehicle is troublesome.

An object of the present invention is to provide a glass run which can be easily fitted to a door sash of a vehicle to improve work efficiency without impairing the appearance.

[0005]

In order to achieve the above object, a glass run according to a first aspect of the present invention has an outer wall portion having a substantially U-shaped groove for guiding a sliding door glass. Outer lip and inner lip, which are formed on the inner wall of the vehicle and the bottom wall and the inner wall of the vehicle, on the inner side of the outer wall of the vehicle and on the outer side of the inner wall of the vehicle, respectively. With the outer molding lip and the inner molding lip, the flange of the door outer panel is inserted between the outer molding lip and the outer wall, and the flange of the door inner panel is inserted between the inner molding lip and the inner wall.

[0007]

According to the glass run of the present invention, since the guide lip for guiding the insertion of the flange of the door outer panel is extended at the door sash side end of the vehicle outer wall fitted to the corner of the door, the vehicle is extended. When fitting into the door sash, it is not necessary to aim and insert the flange of the door outer panel so as to be directly located in the gap formed by the tip of the exterior lip and the exterior wall part. The flange can be easily inserted between the outer lip and the outer wall portion along the guide lip. At the same time, the glass run is fitted into the door sash by inserting the flange of the door inner panel between the interior lip and the interior side wall.

[0008]

Embodiments of the present invention will be described with reference to the drawings. The same parts as those in the conventional example are denoted by the same reference numerals and will be described in detail. FIG. 1 is a perspective view showing a state before a main part of the glass run 1 of the present invention is fitted to the door sash 23, and FIG. 2 is a sectional view taken along line AA of FIG.

The glass run 1 includes a vehicle exterior wall 3, a bottom wall 4, a vehicle interior wall 5, and a vehicle exterior wall 3 which form a groove 2 having a substantially U-shaped cross section for guiding a sliding door glass 24 that moves up and down. Door glass 2 formed on the inside and outside of the car inner side wall 5 respectively
The outer lip 6 and the inner lip 7 are provided in sliding contact with the outer lip 8 and the inner lip 8 formed on the outer side of the outer side wall 3 and the inner side of the inner side wall 5, respectively. The gap L between the outer wall portion 3 serving as the insertion opening of the flange 25 and the tip of the outer molding lip 8 is set to be small as in the conventional example. The glass run 1 is a solid rubber or resin product integrally manufactured by extrusion molding. The part of the door 22 fitted to the corner 22A is manufactured by molding. These structures are the same as those of the conventional example.

Here, a flange 25 of a door outer panel is provided on the side where the bottom wall portion 4 of the vehicle outer side wall portion 3 fitted to the corner portion of the door 22 contacts, that is, on the end portion on the door sash 23 side.
A guide lip 10 for guiding the insertion of the lip is extended.
The reason that the guide lip 10 is extended only to the portion fitted to the corner of the door 22 is that the glass run 1 is inserted into the channel 27 in the door sash 23 to prevent interference with the guide lip 10 except at the corner. This is because the guide lip 10 cannot be extended because it is necessary to avoid it, but it can be freely extended since there is no channel 27 at the corner. It should be noted that there is no problem even if the channel 27 is provided in the corner portion of the scale, since the shape can be arbitrarily changed.

The guide lip 10 has a substantially semi-disc shape, and a flat surface is formed on the side for guiding the insertion of the flange 25 so as to prevent the inserted flange 25 from being caught and to smoothly guide the flange. ing. Guide lip 10
In the present embodiment, the length S in the extending direction is set to be equal to the length in the longitudinal direction of the vehicle outer side wall 3. Although not particularly limited to this length S, it is preferable that the length is at least の or more of the longitudinal length of the vehicle outer side wall portion 3 in order to facilitate the insertion of the flange 25. Guide lip 1
Numeral 0 is a solid rubber or resin product as in the case of the vehicle exterior wall 3.

When the glass run 1 constructed as described above is fitted to the door sash 23, the flange 25 of the door outer panel is inclined with respect to the guide lip 10 as shown in FIG. The flat surface of the guide lip 10 is brought into contact with the edge, and the flange 25
The flange 25 is inserted between the outer molding lip 8 and the outer wall 3 while the edge of the inner wall extends along a flat surface, and at the same time, the door inner is inserted between the inner molding lip 9 and the inner wall 5. This is performed by inserting the flange 26 of the panel. FIG. 3 shows a state where the glass run 1 is fitted to the door sash 23. In this manner, the flange 25 can be reliably inserted into the small gap L only by aligning the edge of the flange 25 with the guide lip 10, so that the fitting to the door sash 23 at the time of assembling the vehicle is facilitated and the working efficiency is improved. improves.

[0013]

As described above, according to the glass run of the present invention, the guide lip for guiding the insertion of the flange of the door outer panel is extended at the door sash side end of the vehicle outer wall fitted to the corner of the door. Therefore, as shown in the conventional example, when fitting into the door sash of the vehicle, the flange of the door outer panel is aimed at so as to be directly located in the gap formed by the outer wall portion and the tip of the outer molding lip. It is not necessary to determine and insert the flange, and the flange can be simply and easily inserted into the gap only by following the guide lip. Therefore, the fitting to the door sash at the time of assembling the vehicle is facilitated, and the working efficiency is improved. In this case, the gap formed by the outer wall portion and the tip of the outer molding lip can be securely and easily fitted to the door sash even if the gap is small, so that the outer molding lip rises from the flange of the door outer panel when inserted and has a good appearance. Damage can be prevented.
