Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle door weather strip, and more particularly to a structure of a terminal portion thereof.

[0002]

2. Description of the Related Art As shown in FIG. 1 (A), a door weather strip 3 is attached around a sashless door 1 of an automobile, and when a door is closed, a space between the door 1 and a door opening edge of a vehicle body is provided. It is designed to be sealed.

As shown in FIGS. 1A and 2, a door weather strip 3 is attached along the peripheral edge of the door 1 and is a tubular general portion 3 formed by extruding sponge rubber.
A, and a terminal portion 3B formed by molding a sponge rubber, which is connected to the end of the general portion 3A and is attached to the front and rear corners of the door 1 so as to wrap it.

The terminal section 3B is more specifically a general section 3A.
And a plate-shaped main body 32 having a shape that encloses a corner of the door 1. A sheet metal insert 4 for imparting shape retention is embedded in the main body portion 32.

The main body 32 has a clip hole penetrating the sheet metal insert. The clip 71 is inserted into the main body 32 and the main body 32 is fixed by press-fitting the clip 71 into the hole provided in the door panel. It Also, the terminal section 3B
A clip hole is also formed in the tube-shaped connecting portion 31 of the above. By inserting the head of the clip 72 into the tube through this hole and pressing the locking leg of the clip 72 into the hole provided in the door panel, The connection portion 31 is fixed. Note that FIG.
6 is a core hole used when molding the terminal portion 3B.

[0006]

By the way, the door weather strip 3 is pressed against the edge of the door opening when the door is opened and closed, and in particular, the terminal portion 3B is rubbed against the weather strip on the body side when the door is opened and closed. A force is often applied in the direction of pulling it away from the main body. For this reason, the head of the clip 72 may come out of the hole of the sponge rubber connection portion 31 and the attachment to the door 1 may become unstable.

[0007] Therefore, the present invention has been made to solve the problem of improving the mounting stability of the terminal portion without adding a new member to the terminal portion of the door weather strip and without impairing the insertability of the clip. It is a thing.

[0008]

As shown in FIG. 1, the present invention provides a general portion 3 at the upper end of a tube-shaped general portion 3A mounted along the periphery of a sashless door 1 of an automobile.
Molded terminal portion 3B including a tubular connection portion 31 connected to A and a main body portion 32 enclosing the upper corner of the door 1.
And the terminal portion 3B, particularly the tubular connection portion 31 thereof.
In the door weather strip 3 in which the clip 72 is fixed with the clip 72, one end of the sheet metal insert 4 embedded in the main body portion 32 of the terminal portion 3B is extended into the connection portion 31 and the notch groove 41 is formed at the extended end. . On the other hand, the core punching hole 6 formed at the time of molding the terminal portion 3B is formed to have a length extending to the position of the notch groove 41. And the clip 72
Is inserted from the core removal hole 6 and locked in the notch groove 41.

[0009]

The clip 72 can be locked to the sheet metal insert 4 with ease of workability by utilizing the core hole 6. The clip 72 is locked to the sheet metal insert 4, and the door 1
Therefore, even if an external force acts on the terminal portion 3B, the connecting portion 31 does not come out of the clip 72.

[0010]

EXAMPLE FIG. 1 shows an example of the present invention. As shown in FIG. 1 (A), the door weather strip 3 has a tube-shaped general portion 3A made of sponge rubber attached along the periphery of the sashless door 1 and both ends thereof (the figure shows only one of them). And a terminal portion 3B made of sponge rubber that is connected to the terminal 1 and wraps the upper corner of the door 1.

As shown in FIG. 1B, the general portion 3A is an extruded body of sponge rubber. The terminal section 3B is the general section 3
It is formed at the end of A by molding, and is composed of a tubular connection portion 31 connected to the general portion 3A, and a plate-shaped main body portion 32 having a shape that encloses the above-mentioned corner angle of the door 1. Body 32
The sheet metal insert 4 which gives shape retention property is embedded in this. In addition, the main body 32 is the door glass 2 [see FIG.
(A)] is provided with a groove portion 303 surrounding the vertical edge.

The terminal portion 3B is formed by inserting the terminal of the general portion 3A into the cavity of the mold and injecting the molding material into the cavity. In this case, the sheet metal insert 4 in which a notch groove 41 is formed at one end as shown in FIG.
Is set so that the one end is in contact with the end of the portion for molding the connecting portion 31. Further, the core 5 [FIG. (D)] is set such that one end is inserted into the end of the general portion 3A and the other end reaches the cutout groove 41 of the sheet metal insert 4. Then, the molding material is injected to mold the terminal portion 3B, and the core 5 is removed after molding.

In the terminal portion 3B of the obtained door weather strip 3, as shown in FIG. 1B, the sheet metal insert 4 having the notch groove 41 is extended in the upper end of the tubular connecting portion 31. The edge is located. In addition, the core hole 6 extending from the connection end with the general portion 3A to the position of the cutout groove 41 is present in the base portion of the connection portion 31.

When attaching the terminal portion 3B to the door 1 [FIG. 1 (A)], the clip 71 is inserted through the hole 42 of the sheet metal insert 4 from the hole provided in the body portion 32 of the terminal portion. Also, insert the head of the clip 72 into the core removal hole 6 and slide it to remove the cutout groove 4 of the sheet metal insert 4.
Insert into 1 and lock. The remaining core hole 6 is closed with an adhesive. Then, the general portion 3A is arranged along the peripheral edge of the door 1, the terminal main body portion 32 is arranged so as to fit into the corner of the door 1, and the locking legs of the clips 71 and 72 are provided at corresponding positions in the holes of the door panel. Push into. Thereby, the terminal portion 3B is fixed.

The tube-shaped general portion 3A is provided with holes at predetermined intervals, and the clip heads are inserted into the holes. Then, the general portion 3A is fixed by pushing these clips into the holes of the panel on the periphery of the door.

[0016]

According to the door weather strip of the present invention, since the head of the clip for fixing the tubular connecting portion of the terminal portion to the door is locked to the sheet metal insert, an external force acts on the terminal portion. However, the above-mentioned connecting part does not come out of the clip. Further, since the clip is fitted into the cutout groove by utilizing the core hole that is continuous with the sheet metal insert and the cutout groove, the clip mounting operation is easy.
