Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention constitutes a center weatherstrip for a double-door type door, and more particularly, a double-door type door.
The present invention relates to a center weather strip attached to only one of the pair of doors.

[0002]

2. Description of the Related Art In an automobile double door type back door,
The center weather strip (hereinafter simply referred to as weather strip) that seals between the abutting ends of a pair of doors is
Conventionally, it is generally attached to the abutting ends of both doors. In addition, a double seal structure is often used in which each weather strip is provided with two seal portions.

FIG. 4 shows a typical example thereof. At a butt end 11 of a pair of doors 1A and 1B, a lip-shaped seal portion 42 is provided on the outer surface side of the door and a hollow section having a circular cross section is provided on the inner surface side. Weather strips 4A and 4B having a seal portion 43 are attached (for example, Japanese Utility Model Laid-Open No. 58-44221).

Recently, however, a double door type door has been used in which a weather strip is attached only to the abutting end of one door, and the other door is closed rearward.

[0005]

By the way, in a double-door type door having a weatherstrip attached to only one door, if one of the weatherstrips as shown in FIG. 4 is used as it is, the following problems occur. .

That is, in FIG. 5, the gap between the abutting ends of both doors 1A and 1B varies depending on the door installation condition. Therefore, the hollow seal portion 43 of the weather strip 4 attached to one of the doors 1A is set to have a sufficient size so as to be able to cope with the case where the variation in the gap is biased toward the larger side. Therefore, when the gap spacing is biased toward the smaller side, when the door 1A is closed from the direction of the arrow C, the hollow seal portion 43 has the end surface 11 (broken line) of the door 1B.
Excessively interferes with the whole and falls outward, and as a result, the hollow seal portion 43 pushes the seal portion 42 outward,
There may be a case where the tip of the seal portion 42 does not sufficiently contact the door 1B. Also, the door closing force is increased.

Therefore, in the present invention, a double-sealed weatherstrip which is attached to only one of the double doors is designed so that the inner sealing portion absorbs the variation in the gap between the two doors and always ensures a good sealing property. It is an object of the invention to provide a structure in which the inner seal portion does not interfere with the outer seal portion.

[0008]

Means for Solving the Problems As illustrated in FIG.
The weather strip 2 of the present invention includes a base portion 21 mounted along the abutting end 11 of one of the pair of doors 1A and 1B forming a double door, and an end portion of the base portion 21 on the outer surface side of the door. When the door is extended and the door is closed, the tip is pressed against the outer edge of the abutting end 11 of the other door 1B and the first seal lip 22 is extended from the end of the base 21 on the inner surface of the door, and the tip is the other when the door is closed. A second seal lip 23 pressed against the end face of the butt end 11 of the door 1B of
At the intermediate position of the second seal lip 23, the lip 23
Bend portions 24a and 24b are formed which are bent when the tip end thereof is pressed against the butt end surface of the other door 1B.

[0009]

Operation: The other door 1B is closed and the one door 1A is closed.
Is closed, the tip of the second seal lip 23 of the weather strip 2 comes into contact with the abutting end 11 of the other door 1B, and the second seal lip 23 has bent portions 24a, 24b.
It is bent at a tilted angle so that the tip end side is erected and is pressed against the butt end. When the closing operation of one door 1A is completed, the tip of the first seal lip 22 is pressed against the outer edge of the other door 1B. The second seal lip 23 is bent at an intermediate position to absorb the variation in the gap distance between the doors 1A and 1B and ensure good sealing performance.
Further, even if the gap is narrow, it does not interfere with the first seal lip 22.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the automobile shown in FIG. 1, the back door is a double door type door and is composed of a pair of doors 1A and 1B. As shown in FIG. 2A, the free end of one door 1A,
That is, the weather strip 2 is attached to the end surface of the abutting end 11 with the other door 1B.

The weather strip 2 has a base portion 21 fixed by a clip 5 in the longitudinal direction along the above-mentioned end surface, and a base portion 21 along the outer surface from the end portion on the outer surface side of the door, and the tip is curved inward. First seal lip 22 extending to the
And a second seal lip 23 whose tip extends from the end of the base portion 21 on the inner surface side of the door toward the tip of the first seal lip 22. The tip side of the second seal lip 23 has a V-shaped cross section and is directed toward the tip direction of the first seal lip 22. One side 231 of the V-shaped tip of the second seal lip 23 is connected to an intermediate position of the first seal lip 22. The one side 231 and the connecting side 232 have substantially the same length and form a V-shaped cross section, and are oriented toward the root of the second seal lip 23.

In the weather strip 2, the V-shaped tip and the connecting side 232 are made of sponge rubber and the other portions are made of solid rubber, which are integrally formed by extrusion molding. A V-shaped top 24a continuing from the connection side 232 to one side 231 of the tip of the second seal lip 23, and a connecting portion 24b between the root of solid rubber and the tip of sponge rubber of the second seal lip 23. Is the second seal lip 2
A bent portion that can be easily bent when a force in the direction of the first seal lip 22 is applied to the distal end portion of 3 is formed.

FIG. 2 (B) shows a state in which the door 1A is closed after the door 1B is closed. When the door 1A is closed in the direction of arrow C, first, the second seal of the weather strip 2 is first sealed. The tip of the lip 23 is the butt end 11 of the door 1B.
The second seal lip 23 is bent at the bent portions 24a and 24b as the door 1A is further closed and rises in the direction of the first seal lip 22 while sliding on the butt end 11. To do. Then, the first seal lip 2
The front end of 2 is pressed against the door 1B to complete the door closing operation.

FIG. 2C shows the door closed state when the gap between the abutting ends 11 of both doors 1A and 1B is small, and the second seal lip 23 has bent portions 24a and 24b.
Is bent and the whole is further erected, so that the change in the gap distance is absorbed.

FIG. 3 shows another embodiment of the present invention.
From the both ends of the base portion 31 of the weather strip 3, a flat plate-shaped first
The second seal lips 32 and 33 extend, and the two seal lips 32 and 33 are connected to each other at an intermediate position by a connecting portion 35 that curves toward the base 31 side. The tip side of the second seal lip 33 is made of sponge rubber and the other portion is made of solid rubber, and the root of the second seal lip 33 made of sponge rubber, that is, the connecting portion with the connecting portion 35 is the bent portion 34. To form.

Also in this embodiment, when the door 1A is closed, the second seal lip 33 bends at its bent portion 34, and due to this bending, the gap distance between the abutting ends 11 of both doors 1A and 1B varies. Is absorbed.

[0017]

As described above, in the weather strip of the present invention which is attached to one of a pair of doors constituting a double door, the middle of the second seal lip which abuts the abutting end of the other door. Since a bent portion whose bending angle changes corresponding to the change in the abutting end distance of both doors is formed in the part, stable sealing performance is always secured regardless of the change in the above distance, and even when the above distance is narrow. Door closing force hardly increases. Further, since the second seal lip bends at its intermediate position and only the tip end side falls up and down corresponding to the above-mentioned interval, even if the above-mentioned interval becomes narrow, the second seal lip becomes the first seal lip. There is no interference.
