Abstract

PROBLEM TO BE SOLVED: To lock an outer garnish to a projecting part and prevent formation of a gap between an outside seal lip and the outer garnish by forming the projecting part along the outer surface of a side wall part adjacent the respective outside seal lips of a die-formed corner run and a vertical run. SOLUTION: On the outer surface of a side wall part 12 adjacent an outside seal lip 11, a projecting part 51 is projected from an area near a die-formed corner run 60 to the outer surface of the side wall part 12 of the die-formed corner run 60. The projecting part 51 allows the die-formed corner run 60 to have increased flexural rigidity at its side edge 12 and nearby portions and have increased degrees of engagement of an outer garnish 40 therewith. Therefore, the bending stress on a hollow seal 2 caused by the pressure of the upper end of door glass 2 forces a curved seal lip 14 to be deformed as if pressed in the direction shown by the arrow E, thereby acting to increase the airtightness of a gap. Thus the action of deforming the entire die-formed corner run 60 is put into equilibrium to prevent excessive deformation of the outside seal lip 11.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a glass run mounted around a door sash of an automobile, and more particularly, to a glass run having an improved structure near a corner formed by molding.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 3, the vicinity of a door sash 3 and a center pillar 4 (partially sash) of a door 1 of a passenger car provide watertightness and airtightness to a door glass 2 and noise and vibration. A glass run 5 made of rubber or resin capable of preventing generation was mounted. In this conventional glass run, the glass run 5 particularly at a portion surrounded by a circle A is partially broken in FIG. 4 and FIG.
As shown in FIG. 6 cut along the BB line, a horizontal run 10 extruded so that it can be mounted along the upper periphery of the door sash 3, and mounted along the side of the center pillar 4 (partially sash). A vertical run 20 extruded as much as possible, and a molded corner run 30 for integrally connecting the horizontal run 10 and the vertical corner run 20 in a substantially L-shape.

[0003] Further, the structure of the conventional glass run 5 will be described.
11, a curved seal lip 14 that curves inward of the vehicle exterior seal lip 11, and a connecting portion 13 that connects the two seal lips 11, 14 with a substantially L-shaped cross section.
4 and a hollow seal formed between the curved seal lip 14 and the connecting portion 13 to define a hollow portion 15a therein, while enabling the upper edge of the door glass 2 to be sandwiched in a slight gap G defined between them. It is extruded so as to be able to press and seal the upper edge of the door glass 2 by means of 15.

The vertical run 20 also has an outer seal lip 11, a curved seal lip 14 curving inward of the outer seal lip 11, and both seal lips, similarly to the horizontal run 10.
A connecting portion 13 connecting the first and second sealing lips 11 and 14 with a substantially L-shaped cross section, and a slight gap G defined between the two sealing lips 11 and 14.
It is extruded so that the side edge of the door glass 2 can be sandwiched and sealed therein, but guides and seals the vertical movement of the side edge of the door glass 2 along the center pillar 4 (partly sash). This is different from the horizontal run 10 in that a hollow seal 15 such as the horizontal run 10 is not provided.

On the other hand, a molded corner run 30 for integrally connecting the horizontal run 10 and the vertical run 20 in a substantially L-shape is formed so as to be curved downward at the corner with respect to the hollow seal 15 of the horizontal run 10. And the connecting portion 13 of the vertical run 20
The gap G defined between the two seal lips 11 and 14 is formed in
The upper end of the door glass 2 which rises through the corner is brought into contact with the corner portion to increase the sealing performance. The opening 21 formed in the connecting portion 13 is a take-out opening of a core for molding the hollow seal 22.

[0006]

However, in the conventional glass run 5, particularly, the molded corner run 30,
FIG. 7 cut along the line BB in FIG. 4 as in FIG.
When the vicinity of the side edge of the upper edge of the door glass 2 rising through the gap G between the two seal lips 11 and 14 gradually increases the contact degree with the hollow seal 22 from the inner surface of the connecting portion 13, The degree of curvature of the corners of the hollow seal 22 is locally unbalanced, and the bending in the direction of arrow D (the direction of the door glass 2) generated on the outer seal lip 11 by the pressing action of the door glass 2 on the hollow seal 22. Stress is also applied to the molded corner run 30 and the vertical run 20
Excessive bending deformation occurs locally on the outer surface of the side wall portion 12 adjacent to each outer seal lip 11 as shown by the solid line from the state of the two-dot chain line, and the outer surface of the side wall portion 12 There is a disadvantage that a gap C that is harmful to the appearance of the vehicle is easily generated between the external garnish 40 and the external garnish 40 that is mounted together.

The present invention has been made to solve the above-mentioned drawbacks of the conventional glass run, and to provide a glass run which has a compact structure and which can effectively prevent the generation of a gap between the exterior garnish and the side wall of the outer seal lip. It is the purpose.

[0008]

The object of the present invention is to:
The outer lip of the car, the curved lip that bends inward of the outer lip of the car, and the connecting part that connects both seal lips, and the side edge of the glass is placed in the slight gap defined between the both lip. A vertical run that holds the door glass to guide the up-and-down movement of the door glass, a vehicle outer seal lip, a curved seal lip, and a connecting portion that connects both seal lips, and the door is within a slight gap defined between the both seal lips. A horizontal run that clamps the upper edge of the glass and makes contact with the hollow seal to increase the sealing performance, and a vertical run and a horizontal run are connected in a substantially L shape, and at the corners, for a horizontal run hollow seal. A mold molding corner run that increases the sealing performance by abutting the corner part of the upper edge of the door glass to the hollow seal that is continuously molded so as to bend downward and hang down is installed around the automobile door sash A glass run that is formed by projecting ridges along the outer surface of the side wall portion adjacent to the vehicle outer seal lips of the molding corner run and the vertical run, and the exterior garnish is locked to the ridges. It is achieved by a glass run characterized by preventing the formation of a gap between the exterior lips and the exterior lips of each of the molded corner run and the vertical run.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the glass run of the present invention will be described below in detail with reference to the accompanying drawings. Note that members or configurations equivalent to those of the conventional glass run 5 shown in FIGS. 3 to 7 will be described using the same reference numerals. The glass run 6 of the present invention is made of rubber or resin in the same manner as the conventional glass run 5 described above, and is formed by integrally molding a horizontal run 10 and a vertical run 50 formed by extrusion into a substantially L-shape with a molded corner run 60. Made up of

Further, the structure of the glass run 6 of the present invention will be described.
Takes exactly the same configuration as the
1. A curved seal lip 14 that curves inward of the vehicle exterior seal lip 11, and a connecting portion 13 that connects the two seal lips 11, 14 with a substantially L-shaped cross section.
4 and a hollow seal formed between the curved seal lip 14 and the connecting portion 13 to define a hollow portion 15a therein while allowing the upper edge of the door glass 2 to be sandwiched in a slight gap G defined between the door seals. It is extruded so as to be able to press and seal the upper edge of the door glass 2 by means of 15.

On the other hand, like the horizontal run 10, the vertical run 50 also includes an outer seal lip 11, a curved seal lip 14 curving inside the outer seal lip 11, and both seal lips.
A connecting portion 13 connecting the first and second sealing lips 11 and 14 with a substantially L-shaped cross section, and a slight gap G defined between the two sealing lips 11 and 14.
It is extruded so that the side edge of the door glass 2 can be sandwiched and sealed inside.
Similarly to the later-described molded corner run 60, the ridge 51 extends from a region close to the molded corner run 60 on the outer surface of the side wall portion 12 adjacent to the outer seal lip 11 to the outer surface of the side wall portion 12 of the molded corner run 60. It is a protruding point.

On the other hand, a molded corner run 60 for integrally connecting the horizontal run 10 and the vertical run 50 in a substantially L-shape is formed so as to be curved downward from the hollow seal 15 of the horizontal run 10 at the corner and hang down. Connecting part 13 of the vertical run 50
The gap G defined between the two seal lips 11 and 14 is formed in
The corner portion of the upper edge of the door glass 2 rising through the abutment is brought into contact with the door glass 2 to increase the sealing performance. The opening 21 formed in the connecting portion 13 is a take-out opening of a core for molding the hollow seal 22. Further, as described above, this molded corner run 60 has a protrusion 51 on the outer surface of the side wall 12 slightly straddling the hollow seal 22 (dotted line).
Extended to 12 outer surfaces. Further, a gap is provided between the protruding ridge portion 51 and the vehicle side seal lip 11 so that the distal end portion of the exterior garnish 40 is fitted therein so as to be freely engageable with the protruding ridge portion 51. Note that the ridge portion 51 is not limited to having a shape that is long in the vertical direction, and may be modified such as providing circular ridges at several places.

The molding corner run 60 in the glass run 6 of the present invention having the above-described structure has the convex streak portion 51 for bending rigidity of the side edge portion 12 and the vicinity thereof and the exterior garnish 40.
2, the bending stress of the hollow seal 22 caused by the pressing force on the upper edge of the door glass 2 is reduced as shown in FIG. 2 cut along the line BB in FIG. 14 is pressed in the direction of arrow E to increase the sealing performance of the gap G, balance the deformation of the entire molded corner run 60, and apply excessive deformation to the outer seal lip 11. Things can now be avoided.

Therefore, a harmful gap C in the appearance of the vehicle, such as the conventional glass run 5 shown in FIG. 7, is not formed between the tip of the exterior garnish 40 and the seal lip 11 on the outside of the vehicle. It is possible to achieve a novel effect that it can be obtained. Further, since the protruding ridge portion 51 is extended near the molded corner run 60 also on the outer surface of the side wall portion 12 of the vertical run 50, the deformation in the region where the curved hollow seal 22 is formed is reduced by the molded corner run 60. It has become possible to maintain an equally stable state.
