It is desirable that an extended reinforcing wall portion that is continuous from the reinforcing wall portion in the direction opposite to the glass run upper side portion is formed in the portion.

Therefore, according to at least the first aspect of the invention, the water guided effect by the lip extension at the molding lip corner can cause the water sealed at the molding lip corner to flow down at a position apart from the lower frame. As a result, water can be prevented from entering between the lower frame and the glass run.

According to the invention described in claim 1, since the lip extension portion that protrudes in the direction opposite to the glass run upper side portion beyond the glass run vertical side portion is formed in the molding lip corner portion, the lip extension portion is formed. With the water guiding effect of the water, it becomes possible to let the water that wraps around the corner side of the molding lip flow down at a position outside the lower frame, preventing water from entering between the lower frame and the glass run. can do.

According to the invention described in claim 2, since the reinforcing wall portion connecting the corner portion of the molding lip and the side wall of the glass run vertical side portion covers and covers the upper end of the lower frame, the molding lip by the reinforcing wall portion is formed. The effect of improving the rigidity of the corners can be expected, and even if water wraps around the corners of the molding lip, it is possible to prevent the water from directly entering between the lower frame and the glass run. .. That is, in the invention described in claim 2, since the reinforcing wall portion is formed in addition to the lip extension portion of the molding lip corner portion, the rigidity of the molding lip corner portion is improved, and the watertightness of the molding lip corner portion with respect to the outer panel is improved. In addition to improving the workability, curling of the corner portion of the molding lip when assembling the glass run can be suppressed, and the workability of assembling can be improved.

According to the invention described in claims 3 to 5, the cover lip portion extending to a position lower than the upper end position of the lower frame is extendedly formed on both the molding lip corner portion and the lip extension portion, or on the molding lip corner portion. Therefore, even if water flows along the lip extension, it is possible to further prevent the water from entering between the lower frame and the glass run.

According to the invention as set forth in claim 6, since the extended reinforcing wall portion which is continuous from the reinforcing wall portion is formed in the lip extension portion, the reinforcing effect of the lip extension portion is exerted together with the corner portion of the molding lip, so that the glass It is possible to suppress the roll-up of the lip extension portion at the time of assembling the run and contribute to the improvement of the assembling workability. Even if roll-up of the lip extension occurs, the extension reinforcing wall increases the resistance during assembly, so the operator can easily notice the roll-up of the lip extension and reassemble it. The urging can prevent the lip extension from being rolled up.

It is an area of the section 10.

On the outer peripheral side of the mold forming portion 10, for example, a fin-shaped partition lip 11 for suppressing wind noise in the sash frame 3 is formed to project, and a rear lower frame (hereinafter, not particularly specified). As far as it can be said, the "lower frame" means the lower frame on the rear side.) A stopper block 12 having a substantially triangular shape, which serves as an abutting portion on the upper end surface of 6, is formed to project. In addition, the molding portion 10 is formed with extended molding molding lips 13 and 14 on the outer side (outside of the room) and the inner side (inside of the room) on the side of the general part 18a of the glass run upper side 8A.

As a result, as shown in FIG. 3, in the glass run upper side portion 8A including the mold forming portion 10, the outer side and inner side molding lips 13 and 14 grip the outer sash 3a and the inner sash 4a of the sash frame 3, respectively.

On the other hand, as shown in FIG. 5, in the glass run vertical side portion 8C including the molding portion 10, the glass run vertical side portion 8C itself is fitted and supported by the lower frame 6 having a channel-shaped cross section. As a result, the mold forming portion 10 is fitted and held in the inner corner portion formed by the upper side portion 3A of the sash frame 3 and the lower frame 6 shown in FIG. The upper end surface of the lower frame 6 contacts the lower surface of the stopper block 12 shown in FIGS. 6 and 7. In FIG. 6, the position of the upper end surface of the lower frame 6 is indicated by symbol E.

As shown in FIG. 7, the inner-side molding lip 14 extended to the mold forming portion 10 side is converged so that its end 14a is interrupted at the boundary with the glass run vertical side portion 8C. .. On the other hand, as shown in FIG. 6, the outer molding lip 13 that is also extended to the mold forming portion 10 side is, as shown in FIG. 6, the upper end surface of the lower frame 6 so as to overlap with the glass run vertical side portion 8C side. It is further extended to a position directly above E and is formed as a wide molding lip corner portion 19 which converges at the portion.

Here, if the molding lip corner portion 19 is a portion of the outer side molding lip 13 that overlaps with the width dimension W of the glass run vertical side portion 8C, in the present embodiment, the molding lip corner portion 19 is It protrudes further in the direction opposite to the glass run upper side portion 8A by a dimension L1 beyond the glass run vertical side portion 8C, and as shown in FIG. A lip extension 20 is formed whose height dimension gradually decreases. The outer-side molding lip 13 extending from the glass run upper side portion 8A is converged by the lip extension portion 20 continuous with the molding lip corner portion 19. Then, in the vehicle side view as shown in FIG. 6, the stopper block 12, the partition lip 11, and the lip extension portion 20 overlap each other in the vehicle width direction.

Showing. Further, FIG. 10 shows an enlarged view of a main part of FIG. Further, FIG. 11 shows a sectional explanatory view of the sash frame 3 corresponding to the section taken along the line GG of FIG. 6, and similarly FIG. 12 is a sectional explanatory view of the sash frame 3 corresponding to the section taken along the line HH of FIG. The figure is shown. 8 to 12, reference numeral 30 denotes a door glass, reference numeral 21 similarly denotes an outer cover arranged on the outside of the sash frame 3, and reference numeral 22 denotes an inside of the sash frame 3. The inner covers are shown respectively.

As shown in FIGS. 6 to 8 and 11, in the portion corresponding to the glass run vertical side portion 8C of the mold forming portion 10, it is easy for the glass run vertical side portion 8C and the molding lip corner portion 19 to overlap each other. Can understand. Then, as shown in FIGS. 6 and 8 to 10, at a position directly above the upper end surface E of the lower frame 6, while connecting the molding lip corner portion 19 and the outdoor side wall 8e of the glass run vertical side portion 8C. A thick film-shaped reinforcing wall portion 23 that covers the upper end surface E of the lower frame 6 is formed. As shown in an enlarged view in FIG. 10, the reinforcing wall portion 23 is formed so as to have almost the same width dimension W (see FIG. 6) as the glass run vertical side portion 8C. Further, an extended reinforcing wall portion 24 is formed extending from the reinforcing wall portion 23 toward the rear surface side of the lip extension portion 20 in the direction opposite to the glass run upper side portion 8A.

In FIG. 6, in order to facilitate understanding of the positions of the reinforcing wall portion 23 and the extended reinforcing wall portion 24, the corresponding positions are intentionally hatched. Similarly, in FIGS. 9 and 10, in order to make the positions of the reinforcing wall portion 23 and the extended reinforcing wall portion 24 easy to understand, the corresponding positions are cross-hatched.

Therefore, according to the glass run 8 having such a structure, as shown in FIGS. 9 and 10, the lower portion of the molding lip corner portion 19 is the reinforcing wall portion 23 and corresponds to the glass run vertical side portion 8C of the mold forming portion 10. Since it is connected to the outdoor side of the section, the rigidity of the molding lip corner portion 19 becomes high, the watertightness of the sash frame 3 to the outer sash 3a is improved, and the molding lip corner portion 19 of the glass run assembly is improved. It is possible to suppress the roll-in and also contribute to the improvement of the workability of assembling the glass run 8.

Further, as is apparent from FIGS. 9 and 10 in addition to FIG. 6, the reinforcing wall portion 23 below the molding lip corner portion 19 is the lower frame on the outdoor side of the glass run vertical side portion 8C equivalent portion of the molding portion 10. The upper end surface E of 6 covers and covers the upper end surface E of the lower frame 6 as if the reinforcing wall portion 23 functions as a lid of the upper end surface E of the lower frame 6. Therefore, for example, as shown by the arrow a1 in FIG. 8, not only does the water entering the back side of the outer cover 21 from the upper side 3A side of the sash frame 3 not directly hit the upper end surface E of the lower frame 6, but also Similarly, as shown by an arrow a2 in FIG. 8, even if water wraps around the back side of the molding lip corner portion 19, unlike the case where the reinforcing wall portion 23 is not set, the water is lower frame. The upper end surface E of 6 does not directly flow into the gap between the lower frame 6 and the glass run vertical side portion 8C.

Then, as shown by an arrow a2 in FIG. 6, the water sneaking around the back side of the molding lip corner portion 19 further flows on the reinforcing wall portion 23 as if it were a trough, as shown by an arrow a3 in FIG. It will be discharged to the outside at a position separated from the lower frame 6.

Further, for example, as shown in FIG. 6, since the lip extension portion 20 is formed to extend continuously from the molding lip corner portion 19, water sealed at the molding lip corner portion 19 including the lip extension portion 20 is As shown by the arrow a4 in the figure, it is transmitted through the lip extension portion 20 and flows down at a position further away from the lower frame 6. Therefore, it is possible to further suppress the occurrence of a situation in which water flows into the gap between the lower frame 6 and the glass run vertical side portion 8C.

Further, as shown in FIGS. 9 and 10, since the extended reinforcing wall portion 24 is formed on the back side of the lip extending portion 20 so as to be continuous with the reinforcing wall portion 23, the rigidity of the lip extending portion 20 is also increased by the reinforcing effect. The height becomes higher, which is further advantageous in suppressing the curling of the molding lip corner portion 19 including the lip extension portion 20 when the glass run is assembled. Further, even if the lip extension 20 is rolled up, the resistance at the time of assembling is increased by the thickness of the extended reinforcing wall portion 24, so that the operator is required to roll up the lip extension 20. It is easy to notice and it is more advantageous to prevent the lip extension 20 from being rolled up by promoting reassembly.

13 to 15 show a second mode for carrying out the vehicle glass run according to the invention, in which the same parts as those of the first embodiment are designated by the same reference numerals, and the description will be repeated. Shall be omitted.

13 shows a portion equivalent to FIG. 6, and FIG. 14 shows a cross-sectional explanatory view of the sash frame 3 corresponding to the cross section along the line D1-D1 of FIG. Further, the sectional explanatory views of the sash frame 3 corresponding to the F1-F1 line cross section and the G1-G1 line cross section of FIG. 13 are completely the same as those of FIG. 9 and FIG. Further, FIG. 15 shows a sectional explanatory view of the sash frame 3 corresponding to the section taken along the line JJ of FIG.

As shown in FIG. 13 and FIGS. 14 and 15, from the reinforcing wall portion 23 below the molding lip corner portion 19 connected to the glass run vertical side portion 8C of the molding portion 10 through the reinforcing wall portion 23. Also, a cover lip portion 25 extending downward to a position lower than the upper end surface E of the lower frame 6 is extended downward. The reinforcing wall portion 23 and the cover lip portion 25 continuous with the reinforcing wall portion 23 have an angled cross section. Then, as shown in FIGS. 13 and 15, the cover lip portion 25 is not limited to a range corresponding to the width dimension W (see FIG. 6) of the glass run vertical side portion 8C, but exceeds the glass run vertical side portion 8C. In the opposite direction to the glass run upper side portion 8A, the cover extension portion 26 is formed to extend together with the reinforcing wall portion 23 and extends to a part of the lip extension portion 20 on the molding lip corner portion 19 side. Note that in FIG. 13, the cover lip portion 25 and the cover extension portion 26 are intentionally hatched and cross-hatched, respectively, in order to facilitate understanding of the positions of the cover lip portion 25 and the cover extension portion 26 continuous with the cover lip portion 25. is there.

As a result, as shown in FIG. 14, at least the upper end portion of the side wall on the outdoor side of the lower frame 6 to which the glass run vertical side portion 8C is fitted and held is provided with the reinforcing wall portion 23 and the cover lip portion having an angled cross section. It is covered with 25 and. In the present embodiment, as shown in FIG. 13, the cover lip portion 25 extends beyond the width dimension W of the glass run vertical side portion 8C and extends in a direction opposite to the glass run upper side portion 8A and projects. The portion is a cover extension portion 26. Further, as shown in FIG. 9 corresponding to the cross section taken along line F1-F1 of FIG. 13, an extended reinforcing wall portion is provided continuously to the reinforcing wall portion 23 on the back surface side of the lip extension portion 20 on the molding lip corner portion 19 side. The point that 24 is formed is similar to the first embodiment.

Therefore, according to the structure of the glass run 8 of the second embodiment, in addition to the reinforcement wall portion 23 that connects the molding lip corner portion 19 to the glass run vertical side portion 8C, the lip extension portion 20 and the extension reinforcement wall portion 24. Since each of them is formed in common with the first embodiment, the same effect as that of the first embodiment can be obtained.

Moreover, in the present embodiment, as shown in FIG. 14, at least the upper end portion of the side wall on the outdoor side of the lower frame 6 is covered with the reinforcing wall portion 23 and the cover lip portion 25 having an angled cross section. Therefore, as described based on FIG. 8, the water that has entered the back side of the outer cover 21 from the upper side portion 3A side of the sash frame 3 flows from the upper end surface of the lower frame 6 to the lower frame 6 and the glass run vertical side portion 8C. It is further advantageous in suppressing the inflow into the gap.

Further, as shown in FIG. 13, since the cover lip portion 25 is formed as the cover extension portion 26 in a direction opposite to the glass run upper side portion 8A beyond the glass run vertical side portion 8C, the cover extension portion 26 is formed. At least the upper end portion of the outdoor side wall of the lower frame 6 is covered with a wider area. As a result, the water that has entered the back side of the outer cover 21 from the upper side 3A side of the sash frame 3 flows from the upper end surface of the lower frame 6 into the gap between the lower frame 6 and the glass run vertical side 8C. It is even more advantageous in suppressing the above.
