DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a glass run for a vehicle which contributes to an improvement in workability of mounting a glass run on a sash rail.

[0002]

2. Description of the Related Art A conventional glass run will be described with reference to FIGS.

As shown in FIG. 2, a door glass run 1 has a basic cross-sectional structure including a vehicle interior standing wall portion 2, a vehicle exterior standing wall portion 3, and a bottom wall portion 5 constituting a glass sliding groove C. A design lip 7 is provided outside each of the upright walls 2 and 3.
9 and a large sliding lip 1 inside each.
1. A small sliding lip 13 is provided. At this time, the large sliding lip 11 on the inside of the vehicle is used in order to place the door glass G on the outside of the vehicle as much as possible.
In other words, this is from the viewpoint of improving design and reducing wind noise.

The glass run 1 is attached to a channel type sash rail 21 formed on a door frame F (FIG. 1) of a front door D by mounting flanges 23, 2 on both sides of the rail.
4 to each of the standing walls 2 and 3 of the glass run 1 and the design lip 7;
Attach them so that they are clamped at 9. In the example shown, 2
Reference numerals 3a and 24a denote raising claws for retaining the weather strip. In addition, there is a thing which does not have this raising nail.

[0005] The sash rail 21 is generally formed such that the outer mounting flange 24 is lower than the inner mounting flange 23 from the viewpoint of visibility from the inside of the vehicle and securing a welding margin for the flange. ing. Correspondingly, the inner wall 2 of the glass run is formed longer than the outer wall 3.

Glass run 1 before mounting on sash rail 1
As shown in FIG. 3, each of the upright walls 2, 3 is connected to the bottom wall 5 due to the lubrication processing on each sliding lip and the bottom wall 5 and the pre-processing in the lubrication processing. 5 is opened to the outside from the time of attachment.

That is, when the glass run 1 is extruded, the rubber immediately after the extrusion is in an unvulcanized state and the belt conveyor B
When the glass run 1 is conveyed while being placed on the like, the shape of the glass run 1 is not stable, so that the glass run 1 is provided with a shape holding material 30 as shown in FIG. Thereafter, when the shape is stabilized by vulcanization, the shape holding material 30 is peeled off. Then, at the time of the lubrication processing on the surfaces of the sliding lips 11, 13 and the bottom wall 5, the processing is performed in a state where the upright walls 2, 3 are expanded so that the surfaces to be processed do not overlap, Finally, the one having the cross-sectional shape is formed.

[0008]

In the process of manufacturing the glass run 1 having the above-described structure and the process of mounting the glass run 1 on the sash rail 21, there are the following problems.

When the glass run 1 is manufactured, the shape-retaining material 30 is applied and the molding is performed. The shape maintaining material 30 needs to be peeled off before the lubrication treatment, and is treated as waste material, so that the material is wasted and the production cost is increased as a whole.

The height of the mounting flanges 23, 24 of the sash rail 21 is different, and the height of the standing walls 2, 3 of the glass run 1 is also different.
3 has to be gripped by hand and assembled so that the bottom wall 5 is substantially parallel to the bottom wall 21a of the sash rail 21, so that the assembly is very troublesome.

In other words, when gripping, if the grip is strong, the bottom wall is liable to tilt due to the balance of force, and it is difficult to make the holding groove 15 parallel to the flange 23. In addition, when the flange 23 is lightly gripped due to fear of the deformation, it must be assembled so that the tip of the flange 23 slides on the outer surface of the vehicle interior standing wall portion 2, which is also difficult to assemble. Furthermore, the design lip opening width W1 is larger than the sash rail outer width W2.
It was difficult to form a large lip, and as shown in FIG. 4, the tip of the vehicle interior design lip 7 entered the opening of the sash rail 21, and the mounting workability was not good.

In this case, as shown in FIG.
If the extruded cross section of the vehicle interior standing wall portion 2 is further expanded outward and the height of the vehicle interior standing wall portion 2 from the bottom wall portion 5 is substantially the same as that of the vehicle exterior standing wall portion 3, the bottom wall portion 5 Is substantially parallel to the bottom wall 21a of the sash rail 21 (FIG. 5), and the design lip opening width W1 is wider than the rail outer width W2 (FIG. 6). However, as shown in FIG. 6, the vehicle interior upright wall portion 2 and the design lip 7 with respect to the vehicle interior mounting flange 23.
And the intersection angle θ with the holding groove 15 formed by the above becomes large, so that the mounting workability cannot be expected to be improved much.

[0013] In view of the above, the present invention has a vehicle interior vertical wall, a vehicle exterior vertical wall, and a bottom wall which constitute a glass sliding groove, and has a cross section having a design lip outside each vertical wall. According to the sash rail in which the inner mounting flange is formed higher than the outer mounting flange, the workability of mounting the glass run having the inner vertical wall portion longer than the outer vertical wall portion on the sash rail is improved. The purpose is to:

[0014]

The glass run of the present invention comprises:
The above problem is solved by the following configuration.

An upright wall on the inside of the vehicle constituting a glass sliding groove;
Includes a vehicle exterior side wall part and the bottom wall portion has a cross section with a design lip on the outside of each vertical wall, the interior side wall part has a vehicle interior side mounting flange and formed higher than the exterior side mounting flange <br/> together they are longer than the vehicle exterior side wall part so as to correspond to the sash rail, the tip end of the interior side mounting flange sliding
In a state before being mounted on the sash rail, the molded cross section of the vehicle interior standing wall is curved and formed to have a continuous outward convex shape, and the height from the bottom wall is set to the vehicle exterior standing wall. Of the holding groove formed by the inner wall and the design lip .

State before assembling to sash rail 21
, The cross-section of the vehicle interior standing wall portion 2 is continuous outside
Is curved in a convex shape (in the illustrated example is formed with a curved portion A), a bottom wall portion substantially with is the same as that of the height of the exterior wall part 3 from 5, interior side wall part 2 bottom wall 5 as formation direction of the holding groove 15 formed in the design lip 7 approaches the formation direction of the vehicle interior side <br/> mounting flange 23 and
Increase the intersection angle with respect to.

Here, it is desirable that the crossing angle α of the holding groove 15 with respect to the bottom wall portion 5 is close to 90 °, and as the crossing angle θ with respect to the vehicle interior mounting flange 23 increases,
The mounting workability is adversely affected.

As a mode of the curved portion A, the vehicle interior standing wall portion 2 is generally formed in a curved (R) shape with the center of curvature being on the glass sliding groove C side. In the case of this cross-sectional shape,
The tip side of the vehicle interior standing wall portion 2 necessarily has a rising shape with respect to the bottom wall portion 5. Further, as shown in FIG. 9, it is formed on the base side of the vehicle interior standing wall portion 2 in a curved shape with the center of curvature being outside the glass sliding groove C. In this case, it is necessary to make the front end side of the vehicle interior standing wall portion 2 stand up.

By forming such a curved portion A on the vehicle interior standing wall portion 2, the height of the vehicle interior standing wall portion 2 from the bottom wall portion 5 becomes substantially the same as that of the vehicle exterior standing wall portion 3. In addition, the intersection angle α of the holding groove 15 with the bottom wall 5 can be increased, and the distance between the tips of the design lips 7, 9 can be relatively increased.

Incidentally, the glass run of this embodiment is usually C
It is manufactured by extrusion using a rubber material such as R or EPDM. The corner is manufactured by molding.

Next, the case where the glass run of the above embodiment is mounted on a sash rail will be described.

The glass run 1 having a sectional shape as shown in FIG. 7 is gripped by hand and mounted on the sash rail 21 in the same manner as in the prior art. At this time, the height of the glass run from the bottom wall portion 5 of the vehicle interior standing wall portion 2 is substantially the same as that of the vehicle exterior standing wall portion 3, and the balance of the force applied to the both standing wall portions 3 and 5 when gripping is performed. Without collapsing, the bottom wall 5 is connected to the bottom wall 21a of the sash rail 21.
Can be gripped so as to be substantially parallel to.

In addition, since the front end side of the vehicle interior standing wall portion 2 has a rising shape, the distance between the front ends of the design lips 7 and 9 is widened, and the intersection angle α of the holding groove 15 with the bottom wall portion 5 is also increased. Since the holding groove 15 and the mounting flange flange 23 are close to each other in parallel, it is easy to form the design lip opening width W1 larger than the sash rail outer width W2. It can be prevented from entering the inside of the unit. When the holding groove 15 is mounted on the mounting flange 23, the bottom wall 5 of the glass run is connected to the bottom wall 2 of the sash rail 21.
It is converted into a force that pushes outward from the vehicle while being substantially parallel to 1a
Because, deformation does not occur as inclined bottom wall 5 (Fig. 7,
8) .
