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 for a vehicle door.

[0002]

2. Description of the Related Art As a conventional glass run mounting structure for a vehicle door, for example, a structure as shown in FIGS. 7 to 10 is known (as a similar technique, Japanese Utility Model Laid-Open No. 63-112126).
(See the official gazette).

Reference numeral 1 denotes a front door of an automobile. The front door 1 has a structure formed by joining a door inner panel 2 and a door outer panel 3 as a whole. The upper side of the waist line L of the front door 1 is a door sash 4, and the lower side is a door body 5.

The door sash 4 is formed by bending and joining a door inner panel 2 and a door outer panel 3 into a predetermined shape (see FIG. 10). The inner edge of the door sash 4 and the waist line L of the door body 5 are joined together. The partitioned opening 7 is opened and closed by the door glass 6. A retainer 9 having a C-shaped cross section is welded to the corresponding surface of the door sash 4 on the vehicle body 8 side along the longitudinal direction, and the retainer 9 is a weather strip for ensuring a sealing property with the vehicle body 8. 1
0 is attached.

Further, the door sash 4 has a portion having a U-shaped cross-section on the side of the opening 7, and a channel member 11 having a U-shaped cross-section is also welded inside this portion.
That is, the door sash 4 and the flanges 4a, 11a of the channel member 11 are welded to each other, and four embossed portions 12 are recessed in the bottom surface 11b of the channel member 11 in a cut-and-raised shape, and the embossed portions 12 of the door sash 4 are formed. Spot welded to the corresponding surface. Therefore, this embossed portion 1
No. 2 has a width sufficient to perform a welding operation by inserting a spot gun for welding.

A glass run 13 for slidably holding the end of the door glass 6 which moves up and down by a pair of lips 13a is fitted in the channel member 11 in a fitted state. This grass run 13 has a straight front portion 14
Further, the front and rear end portions of the upper side portion 18 are connected to the respective upper end portions of the rear side portion 15 via the corner portions 16 and 17.
The upper side portion 18 is fitted into the channel member 11, so that the front side portion thereof forms the oblique side portion 18 a along the shape of the channel member 11.

The front side portion 14 and the rear side portion 15 of the glass run 13 are extruded materials having a constant cross section, and the upper side portion 18 is also an extruded material having a constant cross section. The cross sectional shape of the upper side portion 18 is the front side. It is different from the portion 14 and the like (see FIG. 8). Therefore, the corner portions 16 and 17 for connecting the front / rear side portions 14 and 15 and the upper side portion 18 have a complicated shape in which the cross-sectional shape changes in the middle and is bent in the middle. It is made of wood. Molding with a mold makes it easy to manufacture the complicated shape described above.
The front side portion 14 and the rear side portion 15 of the grass run 13 are
The lower part of the lower rail 19 has entered the door body 5, but the lower part of the door body 5 has the same cross-sectional shape as the channel member 11 in the front and rear lower rails 19. Is fitted to.

[0008]

However, in such a conventional technique, the glass run 13 is mounted in the channel member 11 in a fitted state, and the glass run 13 extends longitudinally in the channel member 11. Only the frictional force acting between the two prevents the displacement in the direction. Therefore, especially when the door glass 6 rises, the door glass 6
When the upper end of the glass run 13 is abutted against the bottom surface of the glass run 13 and a large upward force is applied to the glass run 13, or when the upper side portion 18 of the glass run 13 contracts or distorts due to a material change due to long-term use (ie, environment When receiving a load input), the glass run 13 causes the channel member 1 to
There is a possibility that the position may be displaced upward (in the direction A in FIG. 8) due to the directivity along the hypotenuse portion 18a in the first example. Grass run 13
When the glass shifts to the upper side, the door glass 6 by the glass run 13
The normal holding state of the
Portion 13b protruding outward from the channel member 11 of No. 3
A part of the product will be deformed in appearance, and the appearance will be deteriorated.

Recently, in order to improve the production efficiency of the grass run 13, there is a tendency to increase the molding speed in the manufacturing process of the grass run 13. However, the product manufactured at such a high molding speed has a distortion due to long-term use. Since it easily occurs, the positional deviation of the glass run 13 as described above becomes significant.

Therefore, as a countermeasure for that, the glass run 13 is attached to the channel member 11 by a clip or an adhesive.
However, the number of parts and the number of work steps are increased, so that a more preferable countermeasure is desired.

The present invention has been made by paying attention to such a conventional technique, and can prevent the upward displacement of the grass run in the channel member without increasing the number of parts and the number of working steps. It is intended to provide a glass run attachment structure for a vehicle door that can be used.

[0012]

According to the present invention, a convex portion toward the channel member is formed at a corner portion of a glass run, and the convex portion is formed at a vehicle width direction position offset from a door glass on a bottom surface of the channel member. A convex portion or a concave portion on the glass run side is formed to engage with each other and prevent the glass run from being displaced upward in the channel member.

[0013]

According to the present invention, by engaging the convex portion of the grass run and the convex portion or the concave portion of the channel member, it is possible to surely prevent the upward displacement of the grass run, while the convex portion and the channel of the glass run are prevented. Since the convex portion or the concave portion of the member can be integrally formed at the same time as the manufacturing of the corner portion or the channel member itself, the number of working steps and the number of parts are not increased.

Further, since the convex portion or the concave portion of the channel member is formed at the vehicle width direction position offset from the door glass on the bottom surface of the channel member, even if such a convex portion or concave portion is formed, the door glass is formed. There is no effect on the top dead center position that raised the most.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described below with reference to the drawings. The same parts as those in the prior art are designated by the same reference numerals, and a duplicate description will be omitted.

1 to 3 are views showing a first embodiment of the present invention. On the upper surface 21a of the corner portion 21 on the front side of the grass run 20 according to this embodiment, a projection portion 22 as a "projection portion" is integrally formed at a position near the bending point K of the corner portion 21. Since the corner portion 21 is a molding material, when the corner portion 21 is manufactured by a mold, the protrusion 22
Was also formed at the same time. Height H of this protrusion 22
₁ is the upper surface 21 of the corner portion 21 attached to the regular position
It is set to be equal to or less than the gap S between the a and the bottom surface 23a of the channel member 23.

On the other hand, the embossed portion 24 formed on the bottom surface 23a of the channel member 23 at a position near the upper portion of the corner portion 21 has upper and lower side surfaces 24a,
24b has a slope shape, and has a trapezoidal shape as a whole along the longitudinal direction. And
The embossed portion 2 is provided on the lower adjacent portion of the embossed portion 24.
4, an opening 31 having a width narrower than that of the embossed portion 24 is formed, and a cut-and-raised portion as a “projection” is cut and raised in the channel member 23 at an angle corresponding to the lower side surface 24b of the embossed portion 24. The piece 25 is formed. The width of the cut-and-raised piece 25 is smaller than that of the opening 31, and the degree of protrusion of the cut-and-raised piece 25 into the channel member 23 is the same as that of the gap S. Also,
The cut-and-raised piece 25 is offset from the door glass 6 in the vehicle width direction by X (see FIG. 3). The cut-and-raised pieces 25 are not in strong contact with any part of the corner portion 21 attached to the regular position, and the cut-and-raised pieces 25 do not damage the grass run 20. Further, the lower end 25a of the cut and raised piece 25 has a side surface 22a on the upper side of the protrusion 22.
It is approached in a state close enough to.

According to this embodiment, as described above, the lower end 25a of the cut-and-raised piece 25 formed on the channel member 23 is sufficiently close to the upper side surface 22a of the protruding portion 22 formed on the corner portion 21. Because it is made to face
Even if an upward force is applied to the glass run 20 in the channel member 23 by elevating the door glass 6, the projection 22 is surely engaged with the cut-and-raised piece 25. The displacement in the direction (A direction in FIG. 1) is prevented. Therefore, the normal holding state of the door glass 6 by the glass run 20 is not affected, or a part of the glass run 20 is deformed and the appearance is not deteriorated. Moreover, since the cut-and-raised pieces 25 are offset from the door glass 6 by X in the vehicle width direction, the top dead center position does not change when the door glass 6 is lifted to the maximum.

As described above, the protrusion 22 formed integrally with the corner portion 21 and the cut-and-raised piece 25 formed integrally with the channel member 23 can prevent the glass run 20 from being displaced, so that no clip or adhesive is required. It is possible to reduce the number of parts and the number of work steps. In addition, since the protrusion 22 and the cut-and-raised piece 25 can forcibly prevent the glass run 20 from being displaced upward, the tolerance of the molding strain of the glass run 20 is expanded. Therefore, the grass run 20 produced by increasing the molding speed is said to have a relatively large molding strain.
But you can use it with confidence.

Particularly, in this embodiment, the cut-and-raised pieces 25 are formed on the bottom surface 23a of the channel member 23, and the projections 22 are formed.
Is the upper surface 21a of the corner portion 21 corresponding to the bottom surface 23a.
Therefore, part of the upward force applied to the glass run 20 when the door glass 6 is raised must act in a direction that ensures more secure engagement between the protrusion 22 and the cut and raised piece 25. become. That is, when the door glass 6, which requires the most performance for preventing the position shift of the glass run 20, is raised, the engaging force between the protrusion 22 and the cut and raised piece 25 is increased.

The cut-and-raised pieces 25 are on the bottom surface 23a of the channel member 23, and the protrusions 22 are on the upper surface 21a of the corner portion 21.
In the unlikely event that the projection 22 and the cut and raised piece 25 are formed.
It is also advantageous when the protrusion 22 gets under the cut-and-raised piece 25 due to the disengagement with. That is, even if the protrusion 22 enters under the cut-and-raised piece 25, only the position of the corner portion 21 is lowered, and the width D (see FIG. 3) of the portion of the glass run 20 that receives the door glass 6 does not change. Glass 6
It does not significantly affect the lifting performance of the. On the contrary,
If the cut-and-raised piece 25 is used as the flange 11a of the channel member 23,
And the protrusion 22 is formed on the side surface of the glass run 20 corresponding to the flange 11a,
When the protrusion 22 enters the inside of the cut-and-raised piece 25, the width D may be narrowed, and the door glass 6 may not be smoothly moved up and down. In order to prevent such a situation, in this embodiment, the protrusion 22 and the cut-and-raised piece 25 are formed at the positions as described above.

Further, the cut-and-raised piece 25 may be located at any position where it can be engaged with the projection 22 and does not affect the top dead center of the door glass 6. Therefore, there is a high degree of freedom when changing the position of the cut-and-raised pieces 25, and it is easy to change the design to a different type of door.

In this embodiment, the channel member 23
The cut-and-raised piece 25 is taken as an example of the "projection" formed on the side,
Other shapes may be used as long as they can be engaged with the protrusions 22 and do not affect the top dead center of the door glass 6.

FIG. 4 is a diagram showing a second embodiment of the present invention. In the channel member 32 of this embodiment, the cut and raised piece 33 is used.
The opening 34 formed inside is formed continuously at the front end of the embossed portion 24 without a gap. The angle of the cut-and-raised piece 33 corresponds to the lower side surface 24b of the embossed portion 24, and the cut-and-raised piece 33 is in a state where the lower side surface 24b of the embossed portion 24 and the cut-and-raised piece 33 are straight and continuous. Even when a directional force along the cut-and-raised piece 33 is applied to the lower end 33a of the cut-and-raised piece 33, the cut-and-raised piece 33 is less likely to bend, and the cut-and-raised piece 3
It is also advantageous in terms of strength of 3 itself.

FIG. 5 is a view showing a third embodiment of the present invention. In the channel member 35 of this embodiment, the embossed portion 36 does not have the cut and raised shape, but the upper and lower side surfaces 36a, 36.
In addition to b, it has a raised shape having a side surface 36c in the vehicle width direction. Therefore, the rigidity of the embossed portion 36 is increased and the connection strength by welding to the door inner panel is increased.

FIG. 6 is a diagram showing a fourth embodiment of the present invention. In this embodiment, a protrusion 27 is formed on the upper surface 26a of the corner portion 26, and an embossed portion 29 as a "recess" is recessed on the bottom surface 28a of the channel member 28 corresponding to the protrusion 27. The protrusion 27 is received in the embossed portion 29. Although not shown in the drawing, the embossed portion 29 is formed at a vehicle width direction position offset from the door glass on the bottom surface 28a of the channel member 28. The embossed portion 29 has side surfaces 29 that are substantially vertical to the bottom surface 28a.
a, 29b, of which the upper side surface 29a
Is sufficiently close to the upper side surface 27a of the protrusion 27. In this embodiment, the protrusion 27 has a gap S
Although the height H ₂ is larger than that of the door glass 6, it does not affect the top dead center of the door glass 6 because it is in a state of entering the embossed portion 24.

Also in the case of this embodiment, even if the upward force is applied to the glass run 30 in the channel member 28 by raising the door glass, the side surface 27a of the protrusion 27 is above the embossed portion 29. Since the glass run 30 is engaged with the side surface 29a, the positional deviation of the grass run 30 upward (direction A in FIG. 6) is reliably prevented. As described above, in this embodiment, in order to prevent the displacement of the glass run 30, it is not necessary to specially form the “projection” as in the previous embodiment, and the embossed portion for welding to the door sash 4 is not required. Since it also serves as 29, the manufacturing of the channel member 28 is easy.

In the fourth embodiment, an example in which the "recess" formed in the channel member 28 also serves as the embossed portion 29 for welding to the door sash 4 is shown. It is free to form a dedicated "recess" for engaging the protrusion 27.

In the above-described first to fourth embodiments, the front corner portion 2 of the grass run 20, 30 is used.
The projections (projections) 22 and 27 are formed on the boards 1 and 26, and the cut-and-raised pieces (projections) 25 and 33 and the embossed parts (recesses) 29 are engaged with the structure. A similar structure can be adopted for 17 (see FIG. 7 of the related art). Furthermore, the present invention can be applied not only to the front door of a vehicle but also to the rear door.

[0030]

According to the present invention, by engaging the convex portion of the grass run and the convex portion or the concave portion of the channel member, it is possible to surely prevent the upward displacement of the glass run, but the convex portion of the glass run. Since the convex portion or the concave portion of the channel member can be integrally formed at the same time as the manufacturing of the corner portion or the channel member itself, the number of working steps and the number of parts are not increased. Even if the door is used in a severe environment for a long period of time or a glass run manufactured by increasing the molding speed is used, the lifting performance of the door glass and the appearance quality of the door can be maintained.

Further, since the convex portion or the concave portion of the channel member is formed at the vehicle width direction position offset from the door glass on the bottom surface of the channel member, even if such a convex portion or concave portion is formed, the door glass is formed. There is no effect on the top dead center position that raised the most.
