Abstract

PURPOSE:To improve the sealing properties of a glass run by providing a projection that pushes a window panel outside at the bottom of the glass run base at the end of its rise while making contact with the end face of the window panel. CONSTITUTION:A glass run 10 is provided with an almost U-shaped base 12 fit in the inner circumferential recess of a door sash and seal lips 16a and 16b that are protruded to the inside from the terminal of both inner and outer sides of this base and elastically made to contact the inner and outer surfaces 8a and 8b of a window panel 8. In addition, a projection 20 with a guide surface 20a that pushes a window panel 8 outside at the end of the panel rise while elastically making contact with the end face of the window panel 8 is protruded at the bottom 18 of a base. When the window panel is raised, the window panel 8 is pushed out by a guide surface 20a and powerfully makes elastic contact with the seal lip 16a. As a result, sealing properties are improved.

Description

DETAILED DESCRIPTION OF THE INVENTION a. Field of Industrial Application This invention relates to a glass run for sealing between a window panel and a window panel.

b. Prior art A conventional glass run generally has a structure as shown in FIG. 3 (see Japanese Patent Application Laid-open No. 2003-200102-7J'?, No. 2θ). In Figure 3, / is the roof panel, ko is the roof site rail, 3 is the drip channel, da is the drip molding, ! is the door satshu, Otsu is the door weather string, 7
is the roof side welt, ♂ is the wind panel (glass), and ri is the glass run.

This glass lanter is formed in a symmetrical shape with respect to the reference line 0, is fitted into the door sash j, and is attached to the bottom surface of the roughly U-shaped base a. b comes into contact with the end surface of the wind panel r, and the base? The seal lips protruding from both sides of a and 9d are the wind panels! It is designed to contact the inner and outer surfaces of the edge part of the inner and outer surfaces of the inner and outer edges to seal the inside and outside.

C8 Problems to be solved by the invention In such a glass run, the seal lip 9a,
The close contact force, that is, the sealing force of the wind panel 96 to the wind panel
If rainwater or car wash water comes into direct contact with the door, it is likely to cause a seal failure, and water may enter the glass run, flow down along the glass run, and fall into the door, potentially wetting the parts inside the door and causing rust. Yes, to solve this problem with the seal, it is possible to increase the seal reaction force of the seal lips 9a and 9eL, but the sliding resistance when raising and lowering the wind panel ♂ increases by the amount of increase in seal reaction force. The seal reaction force cannot be increased too much because it increases the lift and lowers the operability.

Also, the outside surface of the door and window panel! It is difficult to reduce the level difference l between the outer surface ♂a of the door sash J and the window panel R, and it is difficult to obtain a flush feeling between the door sash J and the window panel R, which is not desirable not only in terms of appearance, but also in terms of aerodynamic properties and wind noise countermeasures. In order to reduce this step l, it is possible to make the glass run as thin as possible, but the thinner it is, the lower the coolness becomes.
This is hardly a realistic response.

In view of this situation, the present invention has been developed to improve the sealing performance, especially on the outside, which is directly affected by rain water and car wash water, without impairing the ability to raise and lower the wind panel. A means for solving the Od1 problem, which is to provide a glass run that is as small as possible to provide a flash feeling.To achieve the above object, this invention provides a glass run that is as small as possible and provides a flash feeling. In a glass run equipped with a letter-shaped base and seal lips that protrude from both sides of the base and make elastic contact with the inner and outer surfaces of the wind panel, the wind panel is attached to the bottom of the base while elastically coming into contact with the end face of the wind panel. A protrusion with a guide slope that is pushed outward at the end of the ascent is provided.

e. Leprosy example Fig. λ In Fig. 3, / is the roof panel, λ is the roof sight rail formed by joining the outer panel 2a and the inner panel 2b to form a box cross section 2C, and 3 is the one side portion 3a.
is the roof site rail outer spring) v2alc11, and the other side 3b is the drip channel connected to the roof panel/2, and g is the other side 3 of this drip channel 3.
Drip molding attached to b, j is door sash,
The outside (1Nfua quadrip mall, roof panel) which is designed to be continuous with the general surface of the roof panel/ is secured to the outer periphery of the satshu!, and comes into elastic contact with the roof sight rail outer panel 2a when the door is closed. , a door weather strip that seals between the door and the vehicle body, 7 a welt crowned on the lower joint flange 2d of the roof site railco, r a door wind panel (glass),
10 is a grass run according to the present invention.

This glass run IO includes a roughly U-shaped base 12 that is fitted into the inner peripheral recess of the door sash j, and protrudes inwardly from the ends of /4th (a, /4th) on both the inner and outer sides of this base, and The seal lips /Aa, /Ab are in elastic contact with the inner and outer surfaces ra and rb of the base l, and the bottom l of the base l is in elastic contact with the end face of the wind panel ♂, and the wind panel t is moved to the outside (outside of the vehicle) at the end of the panel's rise. A protrusion 20 is provided with a guide slope 20a formed thereon to protrude.

Therefore, this glass run io is shaped asymmetrically with respect to the reference line 0.

With this configuration, when the wind panel ♂ is raised, the guide slope 20a causes the wind panel ♂ to move upward as shown in FIGS.
The outer seal lip/
K makes strong elastic contact with Aa and weak elastic contact with inner seal lip lAb.

Therefore, the sealing performance between the outer seal lip and the wind panel outer surface RA, which are directly hit by rainwater and car wash water, is significantly improved, and water is prevented from entering the glass run 10.Even if some water does enter, It does not fall into the door and wet the inside of the door, so it does not cause rust.

The inner seal lip/A also makes it easier to raise and lower the wind panel r.
Since the elastic contact force t) is weakened, the lifting operation force does not increase significantly, and smooth operability can be ensured. In addition, the step l' between the outer surface ja of the door sash j and the outer surface ra of the wind panel is also reduced by the amount that the wind panel ♂ is pushed outward, creating a flash feeling, improving the appearance quality and improving aerodynamic characteristics and It has a positive effect on wind noise countermeasures.

f9 Effects of the Invention According to the present invention, the practical effects of improving sealing performance, improving appearance quality, aerodynamic characteristics, etc., while ensuring smooth operation of raising and lowering the wind panel. Demonstrate.
