DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

2. Description of the Related Art In an automobile shown in FIG. 9, a glass run for guiding a door glass a up and down is attached to a sash c of a side door b. FIG. 8 is a view showing an example of the mounting structure. In the glass run d, one end of a core bar f of a welt portion e extends substantially in an L shape, and a tip end of the extension portion g has a door glass a. An outer lip h that is in close contact with the inner surface is extended. In addition, the door glass a
The inner lip i which is in close contact with the inner surface of is extended. Grass run d is weld flange b to sash j
And a finisher (not shown) or tape of the same color as the grass run d is mounted on the side surface m of the sash j. This structure is disclosed in Japanese Patent Application Laid-Open No. 8-192637.

[0003]

However, even if the finisher or the tape is the same color as the glass run d, the texture is different and there is a problem in appearance.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a glass run mounting structure capable of improving the appearance without deteriorating the assemblability.

[0005]

In order to solve the above-mentioned problems, the present invention provides a sash, in which one end of a metal core of a welt portion attached to one of the joining flanges is extended substantially in an L-shape. An outer lip that is in close contact with the outer surface of the door glass is provided at the tip of the glass run, and an inner lip that is in close contact with the inner surface of the door glass is provided at the welt. A garnish portion covering the garnish portion is extended from the bent portion of the extension portion, and a locking portion for winding the other tip of the joining flange is provided at the tip of the garnish portion, and the garnish portion is attached to the locking portion. Is characterized in that a first guide surface is formed on the sash from the front and rear surfaces to the side surface when the welt is mounted, and a second guide surface is formed on the sash so as to get over the edge of the joining flange. That.

According to this configuration, when attaching the welt portion of the glass run to the joining flange of the sash, first, the first guide surface of the locking portion comes into contact with the corner between the front and rear surfaces and the side surface of the sash. The glass run moves toward the sash while pressing the guide surface against the corner. For this reason, the garnish portion is elastically deformed to cause the locking portion to ride on the side surface of the sash, and in that state, the welt portion is pushed into the joining flange. When the welt portion is further pushed into the joining flange, the locking portion rides over the edge and engages with the joining flange while the second guide surface slides on the edge of the joining flange.

Further, a pair of glass runs may be installed on adjacent sashes with the welt portion facing the opposite side, and one of the glass runs may be provided with a hollow lip portion to which the locking portion of the other glass run is in close contact. Good.

Further, the garnish portion may be screwed to the waist molding from inside the vehicle body.

[0009]

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

In FIG. 1, reference numeral 1 denotes a glass run, and a welt portion 2 is mounted on a front joining flange 4 of a sash 3 on a front side door side, and one end of a core metal 5 of the welt portion 2 is extended in a substantially L shape. I'm letting it out. Further, an outer lip 8 that is in close contact with the outer surface of the door glass 7 is provided at the tip of the extended portion 6, while an inner lip 9 that is in close contact with the inner surface of the door glass 7 is provided in the welt 2. It is. Further, between the bent portions of the extension portion 6, a seal lip 10 which is in close contact with the front surface 3a of the sash 3 is extended.

The glass run 1 has a garnish portion 11 covering the side surface 3b of the sash 3 extending from the bent portion of the extension portion 6, and a tip of the rear-side joining flange 12 is attached to a tip of the garnish portion 11. An engaging portion 13 to be involved is extended. The surface of the locking portion 13 is curved in a mountain shape, and first and second guide surfaces 14, 15 are provided on both sides of the vertex.
Is formed. The garnish portion 11 is fixed to the side surface 3b of the sash 3 with a double-sided tape 16.
The glass run 1 includes a garnish portion 11 and a locking portion 1.
The inner layer 3 (the portion hatched by the thick line in FIG. 1) is formed of a hard material, and the other portions are formed of a soft material. In addition, the joining flange 12 on the rear side is formed by a so-called hemming process in which the edge of the outer panel 3c is turned over to overlap the edge of the inner panel 3d.

A glass run 1 'substantially similar to that of the front side door is also attached to the sash 3' on the rear side door side, and the locking portion 13 of the glass run 1 on the front side is attached to the glass run 1 '. A hollow lip portion 17 is provided which comes into close contact with the door when the door is closed. Reference numeral 18 denotes a center pillar.

FIG. 5 and FIG. 6 show a coupling structure between the glass run 1 and the waist molding 20. A waist molding 20 is attached to the joining flange 22 of the front side door 21, and a nut 2 is attached to the rear end of the waist molding 20.
An end cap 24 in which 3 is embedded is fixed. Then, the tip is screwed into the nut 23 through the bolt 26 from the hole 25 of the inner panel 3d, so that the glass run 1 is formed.
And the waist molding 20 are connected to each other.

Since the present embodiment is configured as described above,
When attaching the welt portion 2 of the glass run 1 to the joining flange 4 of the sash 3, first, as shown in FIG. 3, the first guide surface 14 of the locking portion 13 is positioned between the front surface 3 a and the side surface 3 b of the sash 3. The glass run 1 moves toward the sash 3 while abutting on the corner and pressing the guide surface 14 against the corner. For this reason, the garnish portion 11 is elastically deformed and the locking portion 13
On the side surface 3 b of the sash 3, and in this state, the welt portion 2 is pushed into the joining flange 4. When the welt portion 2 is further pushed into the joining flange 4, as shown in FIG. 4, the second guide surface 15 slides on the edge of the joining flange 12 on the rear side, and the locking portion 13 holds the edge. It gets over and engages with the joining flange 12.

That is, after the welt portion 2 is mounted, the garnish portion 11 is turned up and the locking portion 13 is connected to the joining flange 12.
It is not necessary to engage with the conventional one, and the workability is the same as the conventional one. By the way, when mounting the glass run 1, first, the welt portion 2 is pushed into the joint flange 4 at the upper end corner of the sash 3, and then the welt portion 2 is gradually pushed downward. It follows the process as shown in the figure.

In this embodiment, since the glass run 1 and the waist molding 20 are fastened together by the bolt 26, the glass run 1 is firmly fixed.

In this embodiment, the locking portion 13 of the glass run 1 on the front side door 21 is brought into close contact with the hollow lip portion 17 of the glass run 1 'on the rear side door, but as shown in FIG. Locking part 13 to seal lip 3
0 and extend the sealing lip 30 to the hollow lip portion 17.
You may make it contact closely.

[0018]

According to the present invention, the garnish portion extending from the glass run covers the side surface of the sash, so that there is no difference in texture and the appearance is improved.

Further, when mounting the glass run,
By simply pushing the welt part into the joining flange of the sash, the locking part can be engaged with the joining flange, and the workability is the same as that of the conventional one.
