Abstract

PROBLEM TO BE SOLVED: To surely prevent door glass from biting into a cover lip regardless of variations in mounting of a molding. SOLUTION: A recess 27 contacted by a molding 26 is provided in the part of the outer surface of the exterior wall 24 of an outer peripheral lip 21 above a point of connection (a) with a lower wall 23, and at least a portion of the recess 27 is formed with a thin wall. When pressure is input from the molding 26 to the exterior wall 24 of the outer peripheral lip 21, the part of the exterior wall 24 near the recess 27 is deformed toward the interior of the vehicle by the pressure and a cover lip 25 is no longer displaced toward the interior of the vehicle. Therefore, the cover lip 25 is hardly displaced even if mounting of the molding 26 varies, and door glass 22 will not bite into the cover lip 25.

2. Description of the Related Art FIGS.
The following has been proposed in the past.

The glass run 1 includes a glass lip base 4 attached to a flange 3 of a door sash 2 and a side lip 6 for sealing a peripheral portion of a door glass 5 on the vehicle interior side, and an outer peripheral end surface of the door glass 5. A hollow outer lip 7 for sealing is extended, and the outer lip 7 of the lip 7 protrudes from the glass run base 4 toward the outside of the vehicle by a predetermined amount, and the lower wall 8 has an outer peripheral end face of the door glass 5. Are coming into close contact. And the outer lip 7
A cover lip 10 having a relatively low protruding cross section is extended from the lower end of the outer side wall 9 of the vehicle.
Is covered with the cover lip 10 so as to improve the appearance quality and prevent the door glass 5 from being sucked out during traveling.

[0004] The glass run is a door sash 2
In a state where the door sash 2 is attached to the vehicle, a metal or resin molding 11 separately provided
The upper half of the vehicle exterior wall 9 is covered in close contact with the vehicle, so that the rubber material surface of the glass run is not greatly exposed to the vehicle exterior.

[0005] This related technique is disclosed in, for example, Japanese Utility Model Application Laid-Open No.
42360 and the like.

[0006]

In the case of the above-mentioned conventional glass run, the cover lip usually overlaps the door glass even when the door glass is maximally displaced to the outside of the vehicle in consideration of the variation in installation of the door glass. Not to wrap
That is, it is designed such that the cover lip does not interfere with the end face of the door glass when the door glass is raised.

However, in practice, the glass run is assembled to the door sash such that the lower edge of the mall is close to the outer wall of the vehicle. When the tip portion is irregularly displaced in the direction of the cabin and the variation in the installation of the mall and the variation in the installation of the door glass overlap, as shown in FIG. This leads to the problem of being bitten by. When the cover lip bites,
Not only does appearance from the outside of the vehicle deteriorate, but this also tends to cause wind and water leaks.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a glass run for an automobile which can surely prevent the cover lip from being caught by the door glass regardless of the variation in the installation of the molding.

[0009]

Means for Solving the Problems As means for solving the above-mentioned problems, the invention according to claim 1 is characterized in that a glass run base mounted on a door sash and a bulge formed from the glass run base to the outside of the vehicle, A hollow outer peripheral lip that seals the outer peripheral end surface of the door glass with the lower wall when the door glass is raised, and extends to the lower end of the outer side wall of the outer peripheral lip to cover the outermost peripheral portion of the highest raised door glass. A cover lip, wherein a substantially upper half of an outer wall of the outer peripheral lip is closely covered with a lower edge of a molding attached to a door sash. A concave portion is provided above the continuous contact point with the lower wall to contact the molding, and at least a part of the concave portion is formed to be thin.

In the case of the present invention, since the concave portion of the outer side wall of the outer peripheral lip is located above the connecting point with the lower wall, when the molding contacts the concave portion at the time of assembly, the molding is performed by the molding. The pressing force deforms the vicinity of the concave portion toward the inside of the vehicle without substantially displacing the cover lip portion.

The invention described in claim 2 is the first invention.
In the invention described in (1), notches are provided at upper and lower positions of the concave portion of the vehicle outer wall. In the case of the present invention, the notch makes it easier to deform the vehicle outer wall due to the pressing force of the molding.

[0012]

Next, an embodiment of the present invention will be described with reference to FIGS.

In the drawings, reference numeral 15 denotes a glass run according to the present invention, 16 denotes a glass run base having a substantially U-shaped cross section which is sandwiched by a welt 19 on a flange portion 18 of a door sash 17, and 20 denotes a glass run base. Reference numeral 16 denotes a side lip extending obliquely upward from the U-shaped bottom to the vehicle outside, and a hollow outer lip extending from the U-shaped tip of the glass run base 16 toward the vehicle outside. The side lip 20 is in close contact with the peripheral portion of the door glass 22 on the inside of the vehicle at the leading edge, and the outer peripheral lip 21 is in close contact with the outer peripheral end surface of the glass 22 at the lower wall 23.

Here, the outer lip 21 is provided with a vehicle outer wall 24 substantially perpendicular to the lower wall 23, and the lower end of the vehicle outer wall 24 is provided with the glass 22 A cover lip 25 is provided to cover the outer peripheral portion of the vehicle. A substantially upper half of the outer surface of the vehicle outer wall 24 is a metal molding 2 attached to the door sash 17.
6 of the outer surface of the vehicle outer wall 24,
A concave portion 27 having a gently curved surface is formed in a substantially central region where the lower end of the molding is in close contact with the lower end of the molding above the connecting point a with the lower wall 23. At least a part of the concave portion 27, in this example, almost the entire region is formed to be thin (see the thickness T in the drawing). Further, near the connecting point a with the lower wall 23 of the vehicle outer side wall 24, and at the connecting point b with the upper wall 28.
Notches 29 and 30 are formed near the hollow portions, respectively.

Since the glass run 15 has the above-described configuration, when the door glass 22 is at its highest position, the side lip 20 is provided on the inner periphery of the door glass 22 and the outer lip 21 is provided on the glass 22. While being in close contact with the outer peripheral end surfaces, the front end of the cover lip 25 covers the outer peripheral portion of the door glass 22 on the vehicle outside.

The position of the cover lip 25 and the like of the glass run 15 are set in consideration of the variation in the construction of the door glass 22 in the same manner as the conventional glass run. Since the concave portion 27 is provided on the outer side surface above the connecting point a with the lower wall 23 and at least a part of the concave portion 27 is set to be thin, the mounting of the molding 26 varies. However, the tip of the cover lip 25 does not significantly displace in the vehicle interior direction.

That is, when the mounting position of the molding 26 is shifted from the reference position in the vehicle direction, the outer wall 24 of the outer lip 21 of the glass run 15 is pressed in the vehicle direction by the lower end of the molding 26. , Car exterior wall 24
Receives the pressing force from the molding 26 at the concave portion 27 above the connecting contact a, and the pressing force is
Before the displacement, the substantially central portion of the vehicle outer side wall 24 is deformed in the vehicle inward direction as shown by a chain line in FIG. Therefore, the cover lip 25 is not greatly affected by the variation in the mounting of the molding 26, and the tip end is always located near the reference position.

Tables 1 and 2 below show that the conventional glass run and the glass run 15 according to the present invention have the door glass 2.
It is the test result which investigated the relationship of the clearance C (refer FIG. 2) between the door glass 22 and the cover lip 25 with respect to the dispersion | variation of 2 building, and the dispersion | variation of installation of the molding 26.

[0020]

[Table 2]

As apparent from Tables 1 and 2,
In the conventional glass run, when the molding 26 is displaced by 0.5 mm to 1 mm inside the vehicle with the door glass 22 displaced 2 mm outward from the reference position, and when the door glass 22 is displaced from the reference position When the molding 26 is displaced by 1 mm to 1.5 mm and the cover 26 is displaced by 1 mm on the inside of the vehicle, the cover lip 25 is bitten by the door glass 22. Even below, the cover lip 25 does not bite.

In the case of this embodiment, the outer lip 2
Notches 29 and 30 are formed in the vicinity of the connection point a on the lower wall 23 side and the connection point b on the upper wall 28 side of the vehicle exterior wall 24, respectively.
Is provided, it is difficult for the pressing force from the molding 26 to be transmitted to the cover lip 25 portion, and this also contributes to suppressing displacement of the cover lip 25.

Therefore, when the glass run 15 according to the present invention is employed, the cover lip 25 is reliably prevented from being caught by the door glass 22, and the appearance is reduced due to the caught and the wind during traveling is reduced. Leakage, water leakage, etc. can be eliminated.

[0024]

As described above, the invention according to claim 1 is
A concave portion is provided on the outer surface of the outer lip of the vehicle outer wall, above the continuous contact with the lower wall, in contact with the molding, and at least a part of the concave portion is formed to be thin, so that the pressing force by the molding is reduced. When input, the vicinity of the concave portion can be reliably prevented from being deformed in the vehicle interior direction and the cover lip is largely displaced in the vehicle interior direction. Even if the number increases, the problem that the cover lip is bitten by the door glass does not occur. Therefore, according to the present invention, it is possible to reliably prevent deterioration in appearance due to biting of the cover lip, wind leakage, water leakage, and the like from the periphery of the glass.

The invention described in claim 2 is the first invention.
In the invention described in the above, since notches are further provided at the upper and lower positions of the concave portion of the vehicle outer wall, deformation of the vehicle outer wall due to the pressing force of the molding is facilitated, and the engagement of the cover lip by the door glass is more reliable. Can be prevented.
