The present invention relates to a glass run mounting structure of a vehicle door.

As the glass guide mounting structure of a conventional vehicle door, for example, the ones shown in FIGS. 7 to 10 are known (for a similar technique, see Japanese Patent Application Laid-Open No. 63-112126).

Reference numeral 1 in FIG. 7 denotes a front door of a motor vehicle, and the front door 1 has a structure formed by joining the door inner panel 2 and the door outer panel 3 as shown in FIG. Above the waste line (L) of the front door 1 is the door chassis 4, and the bottom is the door main body 5. As shown in FIG.

The door chassis 4 is obtained by bending and joining the door inner panel 2 and the door outer panel 3 to a predetermined shape (see FIG. 10), and the inner edge of the door chassis 4 and the door body. The opening 7 partitioned by the waste line L of (5) is opened and closed with the door glass 6. A retainer 9 having a C-shaped cross section is welded in the longitudinal direction to the corresponding surface of the vehicle chassis 8 side of the door chassis 4, and the retainer 9 is ensured airtightness with the vehicle body 8 in the longitudinal direction. There is a weather strip (10).

The door chassis 4 has a portion having a U-shaped cross section at the opening 7 side, and is welded in such a manner that the Chanel member 11 having a U-shaped cross section is also inserted into the inside of the portion. That is, the door chassis 4 and the flanges 4a and 11a of the chanel member 11 are welded to each other, and at the same time, the four embossed portions 12 are bent on the bottom 11b of the chanel member 11. Iii), the embossed portion 12 is spot welded to the corresponding surface of the door chassis 4. Thus, the embossed portion 12 has a sufficient width to insert the spot welder and perform the welding operation.

And in this channel member 11, the glass guide 13 which perturbably grasps with a pair of leaf lip 13a which faces the end of the door glass 6 which moves up and down is fitted in the state fitted. . This glass guide 13 connected the front and rear ends of the upper side part 18 through the corner parts 16 and 17 to each upper end part of the linear front side part 14 and the rear side part 15. It is shaped. The upper edge portion 18 is fitted into the chanel member 11 so that the front portion thereof is an inclined edge portion 18a that matches the shape of the chanel member 11.

The front side 14 and the rear side 15 of the glass guide 13 are extruded members having a constant cross section, and the top side 18 is also an extruded member having a constant cross section. The cross-sectional shape is different from the front edge 14 and the like (see Fig. 8). Therefore, the corner portions 16 and 17 for connecting the front and rear edge portions 14 and 15 and the upper edge portion 18 are formed in a complicated shape in which the cross-sectional shape is changed and bent along the way. It is formed by a form. In the case of molding by mold, the complicated shape as described above is also easy to manufacture. In addition, the lower part of the front side part 14 and the rear side part 15 in the glass guide 13 is fitted in the lower rail 19 which has substantially the same cross-sectional shape as the said channel member 11. .

However, in such a conventional technique, the glass guide 13 is mounted in a state of being fitted into the chanel member 11, and the glass guide 13 in the chanel member 11 prevents the longitudinal direction of the guide. Force is the only frictional force acting between them. Therefore, particularly when the door glass 6 is raised, the upper end of the door glass 6 hits the bottom surface of the glass guide 13 so that a large upward force acts on the glass guide 13 or the upper side of the glass guide 13. When the portion 18 is reduced or twisted due to a material change due to long-term use (ie, when an environmental load input is received), the glass guide 13 is inclined side portion 18a in the chanel member 11. Due to the directionality along, there is a fear of causing a position change in the upper direction (A direction in FIG. 8). When the glass guide 13 is pulled upward, the normal holding state of the door glass 6 by the glass guide 13 is affected and at the same time the portion 13b of the glass guide 13 extending out of the chanel member 11. Appearance deformation, such as the rise of a part of the (발생 上) occurs, and it hurts the beauty.

In addition, in recent years, in order to improve the production efficiency of the glass guide 13, in the manufacturing process of the glass guide (! 3), the molding speed tends to be increased. Since this is likely to occur, the positional pull of the glass guide! 3 as described above becomes remarkable.

Therefore, as a countermeasure, although the glass guide 13 is fixed to the inside of the chanel member 11 by a clip or an adhesive agent, since it leads to an increase in the number of parts and the labor, a more preferable countermeasure is urgently needed. It is required.

SUMMARY OF THE INVENTION The present invention has been made in view of such a conventional technique, and the glass guide of a vehicle door capable of preventing the positional movement of the glass guide upward in the chanel member without causing an increase in the number of parts and labor. It is to provide a mounting structure.

The present invention forms a convex portion facing the chanel member toward the corner portion of the glass guide, and at the vehicle width direction position eccentric with the door glass as the bottom surface of the chanel member, in combination with the convex, in the chanel member of the glass guide. The concave portion or concave portion facing the glass guide side is formed to prevent the positional deflection upward.

According to the present invention, it is possible to reliably prevent the positional movement of the glass guide upward by the combination of the concave portion of the glass guide and the concave portion or the concave portion of the chanel member. The part or concave part can be formed integrally with the production of the corner part and the chanel member itself, and therefore does not cause an increase in the number of work and parts.

In addition, since the concave portion or concave portion of the chanel member is formed at the vehicle width direction position eccentric with the door glass as the bottom surface of the chanel member, even if such a concave portion or concave portion is formed,点) position is not affected.

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. In addition, the same code | symbol is attached | subjected to the part common to the past, and the overlapping description is abbreviate | omitted.

1 to 3 are diagrams showing a first embodiment of the present invention. On the upper surface 21a of the front edge portion 21 of the glass guide 20 according to this embodiment, the projection portion 22 as the "groove" is located at a position close to the bending point K of the corner portion 21. It is formed integrally. Since the corner portion 21 is a formed mold member, when the corner portion is manufactured by the mold, the protrusion portion 22 is also formed at the same time. The height H ₁ of the projection 22 is set to be equal to or less than the gap S between the upper surface 21a of the corner portion 21 mounted at the normal position and the bottom surface 23a of the channel member 23.

On the other hand, in the embossing part 24 formed in the upper vicinity of the said edge part 21 of the bottom face 23a of the chanel member 23, the upper side and the lower side surface 24a, 24b become inclined surface shape. In general, the shape is formed in a longitudinal shape along the longitudinal direction. And the opening part 31 narrower than the embossing part 24 is formed in the lower adjacent part of this embossing part 24, and is formed in the lower surface 24b of the embossing part 24 in the opening part 31. As shown in FIG. A locking piece 25 is formed as a "groove" which is angulated into the channel member 23 at a corresponding angle. The width of the locking piece 25 is smaller than that of the opening 31, and the degree of protruding into the channel member 23 is the same as the gap S. In addition, this latching piece 25 is offset by X in the vehicle width direction with respect to the door glass 6 (refer FIG. 3). The locking piece 25 is not strongly in contact with any part of the corner portion 21 mounted at the regular position, so that the glass guide 20 is not damaged by the locking piece 25. In addition, the lower end 25a of the locking piece 25 faces in a state sufficiently close to the upper surface 22a of the protrusion 22.

According to the present embodiment, as described above, the lower end 25a of the engaging piece 25 formed in the channel member 23 with respect to the upper surface 22a of the protrusion 22 formed in the corner portion 21. Since the projections 22 are sufficiently close to each other, even if an upward force acts on the glass guide 20 in the chanel member 23 by raising the door glass 6, the protrusions 22 are applied to the locking pieces 25. The engagement is assuredly prevented from tilting the position of the glass guide 20 upward (A direction in the first diagram). Therefore, the normal holding state of the door glass 6 by the glass guide 20 is not influenced, or a part of the glass guide 20 is deformed and causes aesthetic appearance damage. Moreover, since the locking piece 25 is eccentrically with respect to the door glass 6 by X in the vehicle width direction, when the door glass 6 is raised to the maximum, the top dead center position does not change.

As mentioned above, since the projection part 22 integrally formed in the edge part 21 and the locking piece 25 integrally formed in the channel member 23 can prevent the positional guide of the glass guide 25, Clips and adhesives are not necessary, and the number of parts and the number of work can be reduced. In addition, since the protrusion of the position upward of the glass guide 20 can be forcibly prevented by the said projection part 22 and the locking piece 25, the tolerance of the shaping | molding twist of the glass guide 20 becomes wider. . Therefore, even if the glass guide 20 manufactured by the high shaping | molding speed of comparatively big shaping | molding torsion can be used, it can be used safely.

In particular, in this embodiment, the engaging piece 25 is formed on the bottom face 23a of the chanel member 23, and at the same time, the protrusion part 22 forms the top face 21a of the corner part 21 corresponding to the bottom face 23a. Since a part of the upward force exerted on the glass guide 20 when the door glass 6 is raised to act in a direction to more securely engage the protrusion 22 and the engaging piece 25, do. That is, when the door glass 6 ascends, where the positional guide preventing performance of the glass guide 20 is most required, the coupling force of the protrusion part 22 and the locking piece 25 becomes high.

In addition, the locking piece 25 is formed on the bottom face 23a of the chanel member 23, and the protrusion part 22 is formed on the upper face 21a of the corner part 21. The engagement of the 25 is also advantageous when the protrusion 22 enters under the locking piece 25. That is, even if the protrusion part 22 enters below the latching piece 25, the position of the edge part 21 only falls, and the width | variety D of the part which the glass guide 20 receives the door glass 6, Since Fig. 3 does not change, there is no significant effect on the lifting performance of the door glass 6. On the other hand, suppose that the engaging piece 25 is formed in the flange 11a of the chanel member 23, and the protrusion part 22 is formed in the side of the glass guide 20 corresponding to the flange 11a, If the projection part 22 enters the inside of the latching piece 25, the said width | variety D becomes narrow, and there exists a possibility that the smooth rise of the door glass 6 may not be made. In order to prevent such a situation from occurring, in the present embodiment, the protrusions 22 and the locking pieces 25 are formed at the positions described above.

Again, the locking piece 25 may be combined with the protrusion 22 and at the same time it may be any position that will not affect the top dead center of the door glass 6. Therefore, when the position of the locking piece 25 is changed, the freedom degree is high, and it is easy to change a design according to the door of another form.

Moreover, in the present embodiment, the locking piece 25 as the "groove" formed on the side of the channel member 23 is taken as an example, but it can be combined with the protrusion 22 and affects the top dead center of the door glass 6. As long as it is a shape which is not given, other shapes may be sufficient.

4 is a diagram showing a second embodiment of the present invention. In the chanel member 32 of this embodiment, the opening part 34 in which the locking piece 33 is formed is continuously formed in the front end of the embossing part 24, without gap. Since the angle of the engaging piece 33 corresponds to the lower side 24b of the embossing part 24, the lower side 24b and the engaging piece 33 of the embossing part 24 are in a straight continuous state. Even when the directional force along the locking piece 33 is applied to the lower end 33a of the locking piece 33, the locking piece 33 is less likely to be bent, which is advantageous in terms of the strength of the locking piece 33 itself. .

5 is a diagram showing a third embodiment of the present invention. In the channel member 35 of the present embodiment, the embossed portion 36 is not folded up to form a raised shape having side surfaces 36c in the vehicle width direction in addition to the upper and lower side surfaces 36a and 36b. Therefore, the rigidity of the embossing part 36 is high, and the connection strength by welding to the door inner panel becomes high.

6 shows a fourth embodiment of the present invention. In the present embodiment, the projections 27 are formed on the upper surface 26a of the corner portion 26, and the embossed as the "grooves" on the bottom surface 28a of the chanel member 28 corresponding to the projections 27. The part 29 is concave, and the said projection part 27 is in the state in which the said embossing part 29 was received. Moreover, although not shown in figure, this embossing part 29 is formed in the vehicle width direction position eccentrically from the door glass of the bottom face 28a of the chanel member 28. As shown in FIG. The embossed portion 29 has side surfaces 29a and 29b that are substantially perpendicular to the bottom surface 28 in the vertical direction, and the upper side 29a of the embossed portion 29 is sufficient with respect to the side surface 27a of the upper side of the protrusion 27. It is in an approaching state. Since the protrusion part 27 of this embodiment is in the state which entered into the embossing part 24, while the height is higher than the clearance gap S, it does not affect the top dead center of the door glass 6. As shown in FIG.

Also in this embodiment, as the door glass is raised, even if an upward force acts on the glass guide 30 in the chanel member 28, the side surface 27a of the protrusion 27 is formed of the embossed portion 29. Since it engages with the upper side surface 29a, a position is prevented from moving upward of the glass guide 30 (FIG. 6A direction). Thus, in this embodiment, in order to prevent the positional guide of the glass guide 30, the embossing part 29 for welding to the door chassis 4 without having to specifically form the "protrusion part" like the previous embodiment is required. Since it is also used, the chanel member 28 can be easily manufactured.

Furthermore, in this fourth embodiment, an example of using the embossed portion 29 for welding to the door chassis 4 as the "jaw portion" formed in the channel member 28 is shown. Apart from the reference numerals), it is free to form a dedicated "groove" for engaging with the protrusion 27.

In the first to fourth embodiments described above, the projections 22 and 27 are formed in the corner portions 21 and 26 in front of the glass guides 20 and 30, and the locking pieces are provided. , 25, 33 and the embossed portion (29), but the structure of the same shape as the rear corner portion 17 (see Fig. 7 of the prior art) can also be adopted. Again, the present invention can be applied not only to the front door of a vehicle but also to the rear door.

According to the present invention, it is possible to reliably prevent the positional movement of the glass guide upward by combining the recessed portion of the glass guide with the recessed portion or the recessed portion of the channel member. Since the concave portion or the concave portion can be formed integrally with the manufacture of the corner portion or the channel member itself, it does not cause an increase in the number of work and parts. And whether the door is used in a harsh environment for a long time or using a glass guide manufactured at a high molding speed, the lifting performance of the door glass and the appearance quality of the door can be maintained.

Moreover, since the recessed part or recessed part of a chanel member is formed in the vehicle width direction position which is the bottom face of a chanel member, and is eccentric with a door glass, even if it forms such a recessed part or a recessed part, the top dead center position which raised the door glass to the maximum. There is no effect.
