Abstract

PURPOSE:To improve workability and water tightness, by a method wherein title structure for door, having a corner piece, of an automobile, an extension part is formed to the portion, extending along a door sash, in a manner. to be protruded from the side wall of the folded part of a glass run, and is brought into contact with a lower sash. CONSTITUTION:A pair of extension parts 11 are formed to a portion, extending along a door sash 2, in a manner to be protruded from the side wall of a moulded part 6b of the folded part of glass run 6, and a lower end part 11b thereof is brought into contact with the upper end of a lower sash 5. This constitution enables reliable positioning of the glass run 6 by means of a corner part between the door sash 2 and the lower sash 5, and permits improvement of a mounting work and water tightness.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to the structure of a molded part of a glass run, for example for an automobile door, and in particular for a door with corner pieces.

BACKGROUND ART As shown in FIGS. 3 and 4, in a car door D,
A corner piece 4 is attached to a corner portion between a door sash 2 attached to the door body 1 and a door waist portion 3, and a lower sash 5 is extended from inside the door body 1 toward the front side of the door sash 2. In some cases, a glass run 6 is fitted to the rear edge of the door sash 5 and the inner edge of the door sash 2.

The glass run 6 is constructed by joining a dogleg-shaped molded part 6b formed by molding to a linear general part 6a formed by extrusion molding, and connects the periphery of the door window glass 0, the door sash 2, and the lower sash 5. However, for example, in the corner portion of the lower sash 5 and the door sash 2, a structure as shown in FIGS. 5 and 6 may be adopted.

That is, a U-shaped part 8 having lip parts 7 on both sides that are in close contact with the door window glass G is formed on the inner circumferential edge, while a U-shaped part 8 is formed on the outer circumferential edge between the bottoms of the door sash 2 and the lower sash 5. A recessed portion 9 is formed to guide the door sash 2, and removal stop portions 10 are formed on both side edges of the door sash 2.
is formed (this similar structure is, for example,
-54419'X).

Problems to be Solved by the Invention Although the molding 1fB6b of the glass run 6 is formed in advance to match the corner portions of the corresponding door sash 2 and lower sash 5, in reality, due to the nature of the glass run 6, which expands and contracts, during work. It has been pointed out that if it is fitted in an extended or contracted state, there is no problem at the crotch portion 6a, but the corner portions may not align with the door sash 2, etc., resulting in poor installation.

Furthermore, when car wash water or the like enters the outer peripheral edge of the glass run 6, the water guided by the concave portion 9 flows downward, and when the water changes direction as it flows to the lower side of the molded portion 6b. It has been pointed out that this water flows into the inside of the vehicle from the gap O formed between the door sash 2 and the lower sash 5 as shown by the arrow.

SUMMARY OF THE INVENTION Therefore, the present invention provides a molded part structure for a glass run which has good installation workability and is highly reliable in terms of watertightness.

Means for Solving the Problems In the glass run fitted to the inner edge of the front side of the door sash and the rear edge of the lower sash extending from the door body toward the front side of the door sash, the glass run is bent. An extending portion that comes into contact with the upper end of the lower sash is provided on a side wall of the lower sash along the door sash.

The glass run is positioned with the extending portion of the working glass run in contact with the upper end of the lower sash, and is attached to the door sash and the lower sash.

On the other hand, if car wash water, etc. accumulates on the outer periphery of the glass run and flows downward, an extension provided on the side wall of the bent part along the satush part will discharge and guide the water flowing from the upper side to the inside of the car. Prevent people from going around.

Embodiment Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings, in which the same parts as those of the conventional structure are denoted by the same reference numerals.

In FIGS. 1 to 4, the glass run 6 is a linear forked portion 6.
It is composed of a dogleg-shaped molded part 6b, and is fitted to the inner edge of the front side of the door sash 2 and the rear edge of the lower sash 5, and the inner circumferential edge is fitted closely with the door window glass G. A U-shaped portion 8 is formed with lip portions 7 on both sides, and a concave portion 9 is formed on the outer periphery to guide water between the bottoms of the door sash 2 and the lower sash 5. The basic structure is the same as that of the prior art in that a pull-out stopper 10 is formed in close contact with the inner wall of the door sash 2 and lower sash 5.

Here, on the side wall of the molded part 6b constituting the bent part of the glass run 6, a pair of extending parts 11 are provided toward the front in a part along the door sash 2.

The extending portion 11 has a front end portion 11 & cut parallel to the arrangement direction of the lower sash 5, and a lower end portion 11b is in contact with the upper end 5a of the lower sash 5.
This extending portion 11 allows the concave portion 9 of the molded portion 6b on the lower sash 5 side to be relatively deep.

According to the above embodiment structure, when installing the glass run 6, the lower end 11b of the extending portion 11 is brought into contact with the upper end 5a of the lower sash 5, so that the glass run 6 can be attached to the corner of the door sash 2 and the lower sash 5. Since the positioning can be performed reliably at the part, the installation work is easy and there is no possibility of installation failure.

In addition, when car wash water or the like enters the outer peripheral edge of the glass run 6, the water flowing downward along the concave portion 9 is transferred to the molded portion 6b.
Even if the water flows to the lower sash 5 side and changes its direction to both sides, it is guided on both the left and right sides by the extending portion 11, so water flows from the gap O between the door sash 2 and the lower sash 5. The water does not go around to the inside of the passenger compartment and is guided to drain as it is.

Further, when the car wash water is directly directed toward the gap C between the door sash 2 and the lower sash 5 by the extending portion 11, it is possible to prevent water from entering from the outside.

As described in detail, the present invention has a great practical effect in that the installation work is easy to perform and the installation is ensured, so that no installation defects occur.

In addition, the water that entered the outer edge of the grass run and flowed downward,
Since the water is reliably guided by the extension, this water does not enter the vehicle interior, and has the effect of being highly reliable in terms of watertightness.
