DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a window molding for a vehicle, a mounting structure thereof, and a method of manufacturing the same.

[0002]

2. Description of the Related Art For example, in a vehicle having a press type door as shown in FIG. 10, a sash portion of a front side door 1 is formed along a side portion of a front window panel G as shown in FIG. 2 extends upward to come into close contact with the weather strip 4 attached to the front pillar 3. The weather strip 4 is fitted to an outer flange 6 of a drip channel 5 attached to the front pillar 3, and an inner flange 7 is provided near the interior of the drip channel 5 in which a window molding 8 is provided. Installed.

The window molding 8 is attached so as to press the upper surface of a front window panel G adhered and fixed to an opening edge flange 9 formed by the front pillar 3. (This similar structure is disclosed, for example, in Japanese Patent Application Laid-Open No. 4-224416).

[0004]

When the sash portion 2 of the front side door 1 comes into close contact with the weather strip 4, the sash portion 2 of the front side door 1 is connected to the weather strip 4, the window molding 8 and the front window panel G. This is advantageous in that a flash surface can be formed at every part. However, when rainwater on the front window panel G gathers on the side of the front window panel G during running on rainy weather, it passes over the window molding 8 and the front side door. There is a problem that it flows around the door glass 1A.
On the other hand, if the drip portion 8B is secured by providing a ridge 8A on the window molding 8 as shown by a chain line in FIG. 6 to prevent this, the above-mentioned problem can be solved. There arises a problem that the line 8A hinders the formation of the flash surface described above.

Accordingly, the present invention provides a vehicle window molding, a mounting structure of the vehicle window molding, and a vehicle molding that can prevent the rainwater on the front window panel from flowing to the side of the vehicle body without obstructing the formation of the flash surface of the vehicle body. The present invention also provides a method for manufacturing a window molding.

On the other hand, as shown in FIG. 2, the rising height of the inner flange 12A of the drip channel 12 to which the side window molding 10 is attached is fixed at a portion extending from the lower end to the upper end of the front pillar 11. The height of the opening edge flange 17 to which the panel G is adhered is higher than the root of the inner flange 12A at the upper end side of the front pillar 11 in accordance with the inclined state of the holding portion 27 of the side window molding 10. At the lower end side, is formed to be lower than the root of the inner flange 12A. still,
In FIG. 2, DM indicates a dam.

Next, a method of manufacturing the side window molding 10 by using an extruder M will be described with reference to FIGS.

As shown in FIG. 3, a main opening 32 formed in the base body 31 for extruding the molding body 24 is formed.
(See FIG. 6) and a sub-opening 35 (see FIG. 6) formed on a movable base 34 slidably attached to the base body 31 via a guide 33 to extrude the holding section 27.
And the inner wall 18 of the leg portion 20 of the molding body 24 and the bottom wall 27A of the holding portion 27 are adjacent to each other. Then, the movable base 34 is attached to the base body 31 with the legs.
20 is slid from the lower end side of the molding body 24 toward the outer surface side of the molding body 24, and the molding body 24 and the holding portion 27 are closed by the main opening 32 of the base body 31 and the sub opening 35 of the movable base 34.
Are extruded to form the side window molding 10 which is integrated with the above. Here, as shown in FIG.
Is a rod 36 engaged with a concave portion 34A provided in the rod 36.
The main material of the holding portion 27 is injected from the nozzle 38 and the auxiliary materials of the upper lip 28 and the lower lip 29 are injected from the nozzle 39 while the above-mentioned various molding materials are slid by the driving device 37 for vertically moving. In addition, 4 in FIGS.
Reference numerals 0 and 41 each denote a material input port.

The molding body 24, the legs 20, the legs 2
The material of each of the projections 22 and 23 around the recessed portion 0 is the base body 3.
1 is inserted from the back side.

As shown in FIGS. 3 and 6, an opening 42 is formed in the movable base 34 from the sub-opening 35 toward a side edge of the movable base 34 near the main opening 32 of the base body 31. ing.

As shown in FIG. 6, the main opening 31 of the base body 31 has an extended opening 43 which is continuous with the main opening 32 around the opening 42 of the movable base 34 and the lap portion. Is formed.

Therefore, according to the side window molding 10 described above, the height of the inner flange 12A of the drip channel 12 of the molding main body 24 from the terminal is not changed and the height between the holding portion 27 and the molding main body 24 is changed. The drip portion D is ensured, so that the flash surface on the front window panel G during rainy weather can be surely spilled to the side of the vehicle body while traveling in rainy weather while achieving a flash surface with the sash portion of the front side door (not shown). Can be prevented.

The above-mentioned side window molding 1
0, the side window molding 10
Is formed so as to be lowered toward the lower end of the front pillar 11 in accordance with the inclined state of the holding portion 27 of the side window molding 10, so that the holding portion 27 is correspondingly formed. By arranging at a lower position, a larger drip portion D can be secured. Here, at the upper end of the front pillar 11, since the holding portion 27 and the opening edge flange 17 are close to the outer surface side of the molding body 24, the molding body 24 can be cut off only by partially cutting off the upper side 25 of the holding portion 27. And the upper molding 13 entering between the front window panel G and the front window panel G.

According to the method of manufacturing the side window molding 10, the holding portion 27 can be smoothly integrated with the molding body 24 and molded, and the holding portion 27 can be formed without changing the sectional shape of the holding portion 27. It can be attached to a desired position of the molding body 24. Since the opening 42 is formed in the movable base 34, the molding body 24 formed from the main opening 32 of the base body 31 from here.
Since the material flows to the side, the adhesive force between the molding body 24 and the holding portion 27 can be increased. Further, since the base body 31 has the expansion opening 43, the opening 42 and the expansion opening 43 overlap. The materials are mixed at the portions, and therefore, the adhesion between the molding body 24 and the holding portion 27 can be further enhanced.

[0031]

According to the first aspect of the present invention, a drip portion is secured between the holding portion and the molding body without changing the height of the molding body. While providing a flush surface with the sash of the side doors, etc., it is possible to reliably prevent rainwater on the front window panel from sneaking into the side of the vehicle body during running on rainy weather, and to connect the vehicle window molding.
The opening edge flange to be attached corresponds to the inclined state of the holding part
And drop it down toward the lower end of the front pillar.
The holding part is placed at a lower position by that amount.
The drip portion can be secured larger by placing it .

[0032]

According to the second aspect of the present invention, the holding portion can be smoothly integrated with the molding main body and molded.
The holding portion can be attached to a desired position of the molding body without changing the cross-sectional shape of the holding portion.

According to the third aspect of the present invention, since the opening is formed in the movable base, the material flows from the opening to the molding main body side formed at the opening of the base main body. Further, according to the invention described in claim 4 , since the expansion opening is provided in the base body, the material is mixed at a portion where the opening and the expansion opening overlap. Therefore, the adhesion between the molding body and the holding portion can be further increased.
