Abstract

PURPOSE:To improve appearance by forming slits in a bottom wall and side walls in the direction of width and mounting a different sealant, with which the slits are covered, on a surface on the door sash side, in glass run structure for an automobile of a portion positioned facing the corner of a door sash. CONSTITUTION:A plurality of slits 12 extending along the direction of width are formed at inervals of a given distance in a bottom wall 4b and side walls 4a and 4b of a glass run base part 4 positioned facing the corner part of a door sash 2. The glass run 4 is curved in a way to forcibly open the slit 12, and a sealant 13 of a sponge is mounted on the outer surface of the glass run base part 4 in a manner to cover the slit 12. By mounting a so formed glass run 21 on the door sash 2, mounting is facilitated and appearance is improved, and a yield can be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a glass run for an automobile, particularly to the structure of a portion corresponding to a corner of a door sash.

BACKGROUND OF THE INVENTION A glass run is attached to a door sash of an automobile along its inner periphery, and the glass run seals the peripheral edge of the door glass when the door glass is closed.

Conventionally, in this glass run, as shown in FIGS. 3 and 4 (the glass run is indicated by 1 in the figures), a part A' corresponding to the straight part A of the door sash 2 is continuously shaped by extrusion molding, and the part A' of the door sash 2 is A portion B° corresponding to the corner portion B is formed by molding so as to join the ends of the extruded portion A′.

This similar structure is shown in, for example, Japanese Patent Laid-Open No. 1-115725.

Problems to be Solved by the Invention However, in the above-mentioned conventional glass structure, as shown in FIG. 4, the joint C between the extrusion molded part A' and the molded part B' is difficult to form a smooth continuous shape. However, there is a problem that the appearance is poor, and furthermore, there is a problem that the molding requires expensive molding costs and that molding defects often occur during molding, resulting in a poor yield.

SUMMARY OF THE INVENTION Therefore, it is an object of the present invention to provide a glass run structure for an automobile that has high appearance quality and can be manufactured at low cost using extremely simple means.

Means for Solving the Problems As a means for solving the above-mentioned problems, the present invention provides a structure for a glass run installed along the inner periphery of a door sash of an automobile. A slit along the width direction was formed, and a separate sealing material covering the slit was attached to the door sash side surface of this area.

Since slits are formed along the width direction in the bottom wall and side wall of the area corresponding to the corner of the door sash, this area can be easily deformed to fit the corner shape of the door sash. The sealing performance of the part is ensured by the sealing material affixed to the glass run side surface.

EXAMPLE Hereinafter, an example of the present invention will be described based on FIG. 1.2. Note that the same reference numerals are used for the same parts as those shown in FIGS. 3 and 4.

In FIG. 1.2, numeral 21 is a glass run for an automobile, which is a mainstay of the present invention, and 3 is a retainer for holding the glass run of the door support/socket 2. The glass run 21 has inner and outer ends of the glass run base 4, which has a substantially U-shaped cross section, on the inside and outside of the vehicle, respectively, and contacts the inner and outer surfaces of the door glass 5, respectively.
It has a basic cross-sectional shape in which the knob 6 and the outer lip 7 are extended.

Reference numerals 8 and 9 are engagement steps formed on the side walls 4a and 4b of the glass run base 4, and when the glass run 21 is attached to the retainer 3, the panel members 10 and 11 constituting the door support/socket 2 are Bent end 10a.

The stepped portions 8 and 9 are locked to 11a.

Here, Doasa Sosh 2 of this Grass Run 21
The part A' corresponding to the straight part of the door assembly 2 has the same structure as described above, but the part B' corresponding to the corner part of the door sash 2 further includes the bottom wall 4C and the side wall 4 of the glass run base 4.
A, 4b are formed with a plurality of slits 12 along the width direction at set intervals, and when the glass run base 4 is curved by pushing open the slits 12 (first
See diagram.

) Outer surface of glass run base 4 (surface on door sash 2 side)
A sponge-based sealing material 13 is attached to cover the slit 12. When a sponge-based material is used as the sealing material 13 in this manner, the sealing material 3 is allowed to stretch to a large extent, so that the work of attaching the glass run 21 to the door sash 2 can be easily performed. The entire area of the glass run 21 is formed by extrusion molding,
After this modeling, a slit 12 is formed at a portion B° corresponding to the corner portion of the door sash 2.

Since the glass run 21 according to the present invention has such a configuration, after it is attached to the door sash 2, the inner lip 6 is removed from the end of the side walls 4a, 4b of the glass run base 4, which is visible to the public.
and the outer lip 7 are integrally extruded over the entire lengthwise direction, and the appearance quality is significantly improved compared to the conventional model in which part B' corresponding to the corner part was molded. improve. Furthermore, since the slit 12 pushed open by the curvature of the glass run base 4 is covered with the sealing material 13, the sealing performance at the portion B' is ensured by this sealing material 13.

Effects of the Invention As described above, the present invention forms slits along the width direction in the bottom wall and side walls of the portion corresponding to the corner of the door sash, so that it can be easily mounted along the corner of the door sash. At the same time, a separate sealing material covering the slit is attached to the door sash side surface of the area corresponding to the corner of the door sash to ensure the sealing performance of this area, resulting in an extremely simple structure. Although,
It becomes possible to manufacture a glass run with a high appearance quality and at a low cost, which is functionally no inferior to the conventional one that uses molding.
