Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a weather strip which is attached to, for example, the periphery of an automobile door opening.

[0002]

2. Description of the Related Art FIGS. 4 and 5 show a conventional example. The weather strip (1) is made of an elastic material such as rubber or plastic, and includes a tubular portion (2) and a mounting portion (3).
(2) consists of a tubular body (4) and a convex seal portion (5) protruding from the outer periphery of the body (4), and the mounting portion (3) has a clip-shaped body (6); And a lip (7) extending from the inside of the main body (6). The weather strip (1) is mounted by fitting the mounting portion (3) to the flange (9) of the peripheral edge of the door opening (8), and when the door (10) is closed, a tubular shape is formed on the peripheral surface of the door (10). The convex seal portion (5) of the portion (2) is in close contact and performs a water stop soundproofing effect.

[0003]

[Problem to be Solved by the Invention] However, in the above conventional configuration, when the door (10) is opened, the outer periphery of the main body (4) of the tubular portion (2) of the weatherstrip (1) and the convex seal portion are provided.
(5) has water W accumulated between the there has been a problem referred to fall in the room, as shown in FIG. 5 spill.

[0004]

Means for Solving the Problems As a means for solving the above-mentioned conventional problems, the present invention comprises a tubular portion (12) made of an elastic material and a mounting portion (13). ) Is a tubular body (14), and a convex seal portion (15) and a lip portion (15A) that are inserted obliquely outward from the outer periphery of the body (14);
A water receiving groove (15B) formed between the convex seal portion (15) and the lip (15A); and a root end of the water receiving groove (15B) inside the main body (14). The present invention provides a weatherstrip (11) comprising a support wall (15D) having a bulging portion (15C), which is extended from the vicinity to the inner wall of the main body (14).

[0005]

[Operation] In the weather strip (11) of the present invention,
When the door (10) is closed, the oblique outside of the outer periphery of the body (14) of the tubular portion (12)
The convex seal part (15) and lip part
(15A) closely contact the periphery of the door (10) with its tip facing outward to form a double sound insulation mechanism. When the door (10) is opened, water W accumulated between the outer periphery of the main body (14) of the tubular portion (12) of the weather strip (11) and the convex seal portion (15) spills. The water W is securely received by the water receiving groove (15B) formed between the convex seal portion (15) and the lip portion (15A) which is projected obliquely outward and enters the room. Is prevented.

The support wall (15) of the weather strip (11)
The bulging part (15C) of D) faces diagonally outward due to its rigidity.
Lip being Sashidesa Te shape retention (15A) carried,
When the lip (15A) is pushed by the door (10), the lip
( 15A) always deforms in the mouth closing direction (Fig. 1 counterclockwise direction)
So that the lip (15A) opens and the water receiving groove (1
5B) so that the water W received in
(15A) The tip does not touch the peripheral surface of the door (10).

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to an embodiment shown in FIGS. 1 and 2. The weather strip (11) is made of an elastic material such as rubber or plastic, and has a tubular portion (12) and a mounting portion (1).
3), the tubular portion (12) comprises a tubular body (14), a convex seal portion (15) and a lip portion which are inserted obliquely outward from the outer periphery of the tubular body (14). (15A), a water receiving groove (15B) formed between the convex seal portion (15) and the lip (15A), and the water receiving groove (1) inside the main body (14).
5B) and a support wall (15D) connected to the inner wall of the opposing body (14) from the vicinity of the root end and having a bulge (15C). Mounting part
(13) comprises a clip-shaped main body (16) and a lip portion (17) inserted from the inside of the main body (16).

The weather strip (11) is mounted by fitting the mounting portion (13) to the flange (9) of the peripheral edge (8) of the door opening. When the door (10) is closed, the weather strip (11) projects as shown in FIG. The sealing portion (15) has its tip directed outward and is in close contact with the peripheral surface of the door (10) to perform a water blocking action, but the lip portion (15A) has a bulging portion (15D) mouth closure due to the rigidity of 15C)
Direction (Fig. 1 counterclockwise direction).
A) is kept in shape so that it does not open, and the lip (15
The abdomen, not the tip of A), makes close contact with the peripheral surface of the door (10). That is , the door (10) is closed as shown in FIG.
When an external force of time f ₁ is applied, the support wall (15D) is pointed by an arrow b.
Direction, and the root end of the support wall (15D) is supported.
It is pulled in the direction of arrow c along the wall (15D) , and
The bulge (15C) of the retaining wall (15D) is more rigid than the surrounding parts.
Because it is higher, the arrow at the root end of the support wall (15D)
It is pulled by the movement in the direction of the mark c and rotated and moved as shown by the arrow d.
Move. Always shown in the arrow a lip portion (15A) is I was but
Deform in the direction. Therefore, the weather strip (11) forms a double sound insulation mechanism by the convex seal portion (15) and the lip portion (15A).

When the door (10) is open, the weather strip (1
Water W accumulated between the outer periphery of the main body (14) of the tubular portion (12) and the convex seal portion (15) is spilled, and the water W is spilled on the lip portion (1).
5A), the convex seal portion (15) and the lip portion (15A)
And is accumulated in the water receiving groove (15B) formed between them. As described above, the lip (15A) is supported by the support wall (15D).
Bulging portion of sender toward obliquely outward by the stiffness of the (15C) of
The closed shape is maintained and the mouth is urged in the closing direction.
As a result , the water W is reliably received by the lip portion (15A).

[0010]

[Effects of the Invention] Accordingly, water spillage from the weather strip of the present invention is reliably prevented, and an extremely excellent sound insulation effect is obtained when the door is closed.
