Abstract

PURPOSE:To reliably wipe off water adhered on a door glass surface by a method wherein an intermediate between the tip and the base end of a seal lip having the tip making contact with the outer surface of a door glass is formed in the shape of a hollow, and a decorative lip having a tip located in the vicinity of the outer surface of a door glass is formed above the seal lip. CONSTITUTION:A weather strip is mounted along a belt line 11 forming the upper edge of a door outer plate 1 of an automobile. A weather strip 4 is an integral press-molded product of rubber, such as EPDM, or synthetic resin, and comprises a mounting base part 41, a molding part 42, a seal lip 43, and a decorative lip 46. A core 47 is embedded throughout a range from the mounting base part 41 to the molding part 42. The decorative lip 46 is extended obliquely upward from the upper end of the mounting base part 41 toward a door glass 2, and the tip thereof is brought into a state to approach the outer surface of the door glass. The seal lip 43 has a hollow part 433 formed approximately in the shape of a circle in cross section between a tip 431 in the shape of a cut and a base end 432 coupled to the mounting part 41. The upper surface and the under surface of the hollow part are filled with bristles 45a and 45b throughout an approximately half range on the door glass 2 side in a state that a portion ranging from the tip 431 to a part located a slight distance away from the tip is left unfilled.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a weather strip for automobiles, and more particularly to a weather strip that is attached along the belt line of a door and wipes the outer surface of the door glass to remove water when the door glass is raised or lowered. It is something.

[Prior Art] A weather strip is attached to the outer panel of an automobile door along the belt line to drain water from the outer surface of the door glass.

As shown in FIG. 5, the Unisa strip 4A extends obliquely upward from the mounting base 41 toward the outer surface of the door glass 2, and includes a seal lip 43A whose tip side surface is pressed against the outer surface of the door glass 2. This seal lip 43
When the door glass is raised or lowered, the outer surface of the door glass is wiped to drain water (Utility Model Publication No. 123930/1983).

In the figure, 1 is the door outer panel, 11 is the belt line, and 44
is an auxiliary seal lip, 45 is a flock, and 5 is a clip.

However, in this type of seal lip 43A, water cannot be completely wiped off because the side surface of its tip comes into surface contact with the outer surface of the door glass.

Moreover, this type of seal lip 43A is provided with flocking 45 in order to reduce the sliding resistance with the door glass 2 and to prevent sand, clumps, and other dust from getting caught between the door glass 2 and the seal lip 43A. Even if the door glass 2 is wiped, water remaining between the flocked hairs adheres to the glass surface.

Water adhering to glass surfaces impairs visibility. In particular, the front door improves side and rear visibility for the driver.
It is desirable that the water on the glass surface be completely wiped off.

[Issues to be Solved by the Present Invention 1JTl Therefore, an object of the present invention is to provide a weather strip that can reliably wipe away water adhering to the outer surface of a door glass when the door glass is raised and lowered.

[Means for solving problems] As illustrated in FIG. 1, the present invention extends the seal lip 43 from the mounting base 41 in a direction perpendicular to the two surfaces of the door glass, and also extends the seal lip 43 from the mounting base 41 to the base end 432. A hollow part 433 is formed in the intermediate part between the seal lip 43 and a flock 45a is provided on at least the upper surface of the seal lip 43, and the upper end of the mounting base 41 extends in the direction of the door glass 2 and its tip is close to the outer surface of the door glass 2. It is characterized in that a designed lip 46 is formed to cover the upper part of the seal lip 43.

[Operations and Effects] Since the seal lip 43 has the hollow portion 433, it is easily bent, and the seal lip 43 is reversed downward and upward as the door glass 2 is lowered and raised. and tip 43
1 wipes water off the outer surface of the door glass 2.

As shown in FIG. 2, when the door glass is lowered, the flocking 45a contacts the outer surface of the door glass directly above the tip 431 of the seal lip 43 to wipe away dust on the glass surface.
No dust gets caught between No. 31 and the outer surface of the door glass. Even if water remaining on the flocked hair 45a adheres to the glass surface when the door glass is lowered, it is completely wiped off by the seal lip tip 431 when the door glass is raised.

The design lip 46 hides the seal lip 43 and improves the appearance along the belt line 11.

Note that the flocking 45b may also be provided on the lower surface side of the seal lip 43. This flocked hair 45b prevents the outer surface of the glass from coming into direct contact with the lower side surface of the seal lip hollow part 433 when the door glass is raised, thereby reducing sliding resistance.

[Embodiment] As shown in FIG. 1, a weather strip 4 is attached to the belt line 11 without the upper edge of the outer door panel 1 of an automobile.
is installed.

The weather strip 4 is an integrally extruded body of rubber or synthetic resin such as EPDM or PVC, and includes a mounting base 41, a molding part 42, a seal lip 43, and a design lip 46. It is embedded and attached to the door outer panel 1 with clips 5 at the attachment base 41.

The design lip 46 extends from the upper end of the mounting base 41 to the door glass 2.
It extends diagonally upward toward the front, and its tip is close to the outside surface of the door glass.

The tip 431 of the seal lip 43 has a cut shape. and a distal end 431 and a proximal end 4 connected to the mounting base 41.
A hollow portion 433 having an approximately circular cross section is formed between the hollow portion 433 and the hollow portion 32 . The upper and lower surfaces of the seal lip 43 have tips 4
3], the flocks 45a and 45b are planted in approximately half the area on the door glass 2 side, leaving a slight distance from the door glass 2. The seal member 43 extends from the mounting base 41 in a direction substantially perpendicular to the outer surface of the door glass.

In the weather strip 4 configured as described above, when the door glass 2 soiled with rainwater and dust begins to descend in the closed state, the seal lip 43 is inverted downward by the hollow portion 433 as shown in FIG. , the upper edge of the tip 431 and the flocking 45a are pressed against the outer surface of the door glass,
In this state, the door glass 2 continues to descend. At this time, most of the water and dust on the outer surface of the door glass is removed by the flocking 45a, and the remaining water and dust are removed by the seal lip tip 4.
It is removed in 31. In this case, although most of the dust on the outer surface of the door glass is removed by the flocking 45a, the dust does not get caught between the glass surface and the tip of the seal lip and damage the glass surface.

Next, when the door glass 2 starts to rise, the seal lip 43 flips upward as shown in FIG. continue. In this process, even if there is some residue left when the door glass is lowered, it is completely removed by the tip 431.

In addition, if the flocking 45b is located closer to the outside of the door glass 2 due to variations in the installation of the door glass 2, the door glass 2 will be directly pressed against the lower side of the hollow part 433 and the sliding resistance will rise. It plays a role in preventing

The seal lip 43 has flocked hair 45a on its upper surface,
Although the appearance itself is not necessarily good, since it is covered with the design lip 46 located above, the appearance along the waistline 11 is good.

FIG. 4 shows another embodiment, in which the mounting base 41 including the molding part 42 and the designed lip 46 of the Unisus L-lip 4 and the seal lip 43 are made of different materials.

That is, it is desirable that the tip 431 of the seal lip 43 has as little sliding resistance as possible against the outer surface of the door glass 2.

For this reason, for example, the seal lip 43 is made of diene rubber, and its tip 431 is treated with chlorine to give it lubricity. The weather strip 4 is manufactured by integrally extruding, for example, EPDM rubber that constitutes the mounting base 41 and diene rubber that constitutes the seal lip 43. Mounting base 41
It is also possible to have a structure in which the seal lip 43 and the seal lip 43 are separate parts, and these are bonded or fitted together. The other structure is substantially the same as the previous embodiment.

Therefore, the Unisa strip of the present invention can completely wipe off water adhering to the glass surface, and the glass does not get scratched due to dust being trapped, and the appearance is good.
