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 A glass run c is attached to a sash b of a side door a of an automobile shown in FIG. Specifically, as shown in FIG. 5, a glass run main body e is attached to the channel portion d of the sash b, and the outer lip h is extended from the glass run main body e so as to wind the flange portion g of the outer panel f. It is.

By the way, the thickness of the sash b tends to gradually decrease as it goes upward due to design requirements. For this reason, the step j between the flange portion g of the outer panel f and the general portion i gradually increases as going downward. By changing the thickness of the outer lip h in accordance with the step j of the sash b, the glass run c attached to the sash b makes the surface of the outer lip h substantially flush with that of the general outer panel portion i. ing.

[0004]

When the glass run c is formed, the glass run main body e is previously formed by extrusion, the glass run main body e is put into a mold, and the outer lip h is formed by injection molding. Although joined, the outer lip h tends to open more outward from the joint than the designed shape due to the influence of the injection pressure of the material. For this reason, the outer lip h rises from the outer panel general portion i, and the appearance is impaired. Therefore, Japanese Patent Application Laid-Open No.
As shown in JP-A No. 9325, a step is formed in a joint portion of the glass run main body e with the outer lip h, and a compressive force at the time of material injection is applied to this portion, so that the outer lip h is formed inside when releasing the mold. However, it was not possible to completely prevent the outer lip h from rising.

[0005] In some cases, the elasticity of the outer lip h deteriorates with time, causing the outer lip h to float.

Further, in the structure of the outer panel f, it is necessary to provide a large step j below the outer panel f, so that there is a drawback that the drawing at the time of forming is deep and forming is difficult.

SUMMARY OF THE INVENTION In view of such circumstances, an object of the present invention is to provide a glass run mounting structure that can completely prevent the outer lip from being lifted up and can easily form the outer panel.

[0008]

According to the present invention, a step is formed between a flange portion joined to a side wall of a channel portion on a side edge of an outer panel and a general portion of the outer panel. The step is gradually increased toward the lower side of the sash, and the outer lip is extended from the glass run body attached to the channel portion so that the flange portion is involved and the outer lip is extended to the surface of the outer panel general portion. In the structure which is substantially flush with the above, while the flange portion is raised from the channel portion side wall to form a gap, a projection protruding into the gap is provided on the back surface of the outer lip, and the flange portion is further raised. A locking portion is provided in the portion, and an engaging portion engageable with the locking portion when the glass run body is attached to the channel portion is provided on the projection. And wherein the digit.

With this configuration, even when the outer lip is opened outward, when the glass run body is mounted on the channel portion, the projection on the back surface of the outer lip abuts on the raised portion of the flange portion, and the outer lip is opened. As a result, the outer lip does not rise from the outer panel general portion. Further, even when the outer lip receives an external force in the direction in which the flange portion extends, the outer lip does not turn up significantly because the engaging portion of the projection is engaged with the locking portion of the outer panel. Further, the step of the outer panel is reduced by the height of the flange portion, and the drawing at the time of molding becomes shallower.

Further, one wall of a bracket having a substantially L-shaped cross section may be joined to the bottom wall of the channel portion, and the other wall of the bracket may be joined to a raised portion of the flange portion.

Further, the locking portion may be a cut-and-raised piece of a bracket, and the engaging portion may be a hook formed at a tip of a projection.

Still further, the engaging portion may be a hole of a bracket, and the engaging portion may be a hook formed at a tip of a projection.

Further, a core material may be inserted into the projection.

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

FIG. 1 is an exploded view of a portion surrounded by a dotted line B in FIG. In the figure, reference numeral 1 denotes a sash, and a flange portion 3a of an outer panel 3 is joined to one side wall 2a of a channel portion 2 and an inner panel 4 is joined to the other side wall 2b. The outer panel 3 has a step G between the flange 3a and the general part 3b.

The flange 3a protrudes from the side wall 2a of the channel portion 2 except for the upper end thereof to form a gap 5, and the amount of the protuberance is lowered below the sash 1 corresponding to the step G of the outer panel 3. By gradually increasing the height, the step g from the outer panel general portion 3b is made substantially constant. Also, one wall 6a of a bracket 6 having a substantially L-shaped cross section is joined to the bottom wall 2c of the channel portion 2, and the other wall 6b of the bracket 6 is joined to a raised portion of the flange portion 3a. is there. Further, a plurality of cut-and-raised pieces 7 as locking portions are formed on the wall 6b of the bracket 6 at predetermined intervals in the vertical direction.

Reference numeral 8 denotes a glass run, and the outer lip 10 is extended from the main body 9 mounted on the channel portion 2 so as to wind the flange portion 3a. The outer lip 10 gradually increases the width L of the connecting portion 10a as it goes downward in correspondence with the step G of the outer panel 3 so that the surface of the covering portion 10b is different from that of the outer panel general portion 3b. Almost flush. A plurality of protrusions 11 are provided on the back surface of the covering portion 10b of the outer lip 10 at predetermined intervals in the vertical direction corresponding to the cut-and-raised pieces 7 of the bracket 6, and are engaged with the tips of the protrusions 11. A hook 12 is formed as a part. When the glass run main body 9 is mounted on the channel portion 2, the hook 12 is engaged with the cut-and-raised piece 7 of the bracket 6.

Since the present embodiment is configured as described above,
Even when the outer lip 10 is opened outward, when the glass run body 9 is mounted on the channel portion 2, the projection 11 on the back surface of the outer lip 10 abuts on the raised portion of the flange portion 3a, and the opening of the outer lip 10 is corrected. Therefore, the outer lip 10 does not rise from the outer panel general portion 3b. In addition, since the outer lip 10 and the projection engaging groove 11 are not joined but are integrally formed, there is no opening between them. Even if the outer lip 10 receives an external force in the direction in which the flange portion 3a extends, the hook 12 of the projection 11 is engaged with the cut-off piece 7 of the bracket 6, so that the outer lip 10 is not significantly turned up. Absent. Further, the step g of the outer panel 3
Is reduced by the amount of protrusion of the flange portion 3a, so that the drawing at the time of molding becomes shallow, and there is also an effect that molding is facilitated.

In this embodiment, the hooks 12 of the projections 11 are engaged with the cut-and-raised pieces 7 of the bracket 6, but as shown in FIG.
The hook 12 of the projection 11 may be engaged with the hole 20.

Further, as shown in FIG. 4, a core material 21 made of a hard resin may be inserted into the projection 11 to reinforce it.

[0021]

According to the present invention, even when the outer lip is opened outward, when the glass run body is mounted on the channel portion, the projection on the back surface of the outer lip comes into contact with the raised portion of the flange portion, and the outer lip is formed. The outer lip does not rise from the outer panel general part because the inclination of the outer panel is corrected.

Even when the outer lip receives an external force in the direction in which the flange extends, the engagement portion of the projection is engaged with the engagement portion of the outer panel. .

Further, since the step of the outer panel is reduced by the height of the flange portion, there is also an effect that the drawing at the time of molding becomes shallower and the molding becomes easier.
