Abstract

PURPOSE:To reliably wipe off water adhered on a door glass surface by a method wherein a dewatering blade having a hollow part formed between a tip and a base end is located under a seal lip making contact with the outer surface of a door glass to wipe it off, and at least the upper surface of the dewatering blade is filled with bristles. CONSTITUTION:A weather strip 4 mounted along a belt line 11 of a door outer plate 1 of an automobile door having a door mirror is an extrusion-molded product of rubber and comprises a mounting base part 41, a molding part 42, a seal lip 43, and an auxiliary seal lip 44. The seal lips 43 and 44 are filled with bristles 45, and a core 47 is embedded throughout a range from the mounting base part 41 to the molding part 42. In which case, a longitudinal groove 46 is formed in the mounting base part 41 of the weather strip 4 and in a position under the root of the seal lip 43 to mount a dewatering blade 48. The dewatering blade 48 has a hollow part 483 formed in the shape of a circle in cross section between a tip 481 making contact with the outer surface of a door glass 2 and a base end 482. The upper surface of the tip part and the under surface of the hollow part 483 are also filled with the bristles 45 in a state that the upper surface of the hollow part 483 and an edge part are slightly left unfilled.

[Prior Art] Unisa strips are attached to the outer panels of automobile doors along the belt line. As shown in FIG. 6, this type of Unisa strip 4 has a seal lip 43 that extends obliquely upward from a mounting base 41 toward the outer surface of the door glass 2, and has a side surface of the tip pressed against the outer surface of the door glass 2. This seal lip 43 is designed to wipe off the outer surface of the seal lip 43 and drain water when the door crow goes up and down (
Utility Model No. 52-123930). In the figure, 1 is a door outer panel, 11 is a belt line, 5 is a clip for attaching the mounting base 41 to the door outer panel 1, and 45 is a flock.

However, with such a draining structure, the side surface of the tip of the seal lip 43 makes surface contact with the outer surface of the door glass, so water cannot be completely wiped off, and it is inevitable that some water will remain. In addition, the seal lip 43 is coated with flocks 45 in order to reduce the sliding resistance with the door glass 2 and to prevent dust such as sand and dust from getting caught between the seal lip 43 and the door glass 2. Then, the water will stick to the crow's surface.

[Means for Solving the Problems] As illustrated in FIG. 2, the present invention provides a seal lip 43 that extends from the mounting base 41 in the direction of the door glass 2 and has a tip 481 in contact with the outer surface of the door glass 2. A draining blade blade 48 having a hollow portion 483 between the end 482 and the tip 481 is provided with the upper end of the hollow portion 483 close to the lower surface of the seal lip 43, and at least the upper surface of the draining blade 48 is provided with flocked hair 45. It is characterized by having undergone. The draining blade 48 does not necessarily need to be provided over the entire length of the weatherstripping; for example, in the case of a front door with a door mirror, it is sufficient to wipe off the door crow within the range where the driver can see the door mirror through the door glass.

As shown in Figure 4, when the door glass is raised, the water adhering to the glass surface is completely wiped away by the tip 481 of the draining blade 48.Then, the glass surface from which the water has been removed rises. However, at this time, the seal lip 43 is pushed up by the hollow part 483 of the draining blade 48, and is no longer in contact with the door glass surface. hair transplant 45
The water rises completely removed without any remaining water sticking to it. The draining blade 48 has a hollow part 483
By providing this, the door glass can be easily reversed as the door glass moves up and down. Furthermore, flocking 45 is provided on the upper surface of the draining plate 48.
When the door glass is lowered, as shown in FIG.
81 and the glass surface do not get caught in the duct, and the glass surface is prevented from being scratched by the tact.

In the weather strip of the present invention constructed as described above, when the door glass 2 is lowered as shown in FIG.
Most of the hair is wiped off on the side where the flocked hair 45 of No. 3 is applied. The draining blade 48 is reversed as the door glass 2 is lowered. At this time, the outer surface of the door glass is wiped with the upper edge of the tip 481, but since most of the dust is removed along with the water on the glass surface by the flocking 45 of the blade 48 immediately above it, the edge of play 1-48 and the glass There is almost no dust trapped between the glass surface and the glass surface, so the glass surface will not be scratched.

On the other hand, when the flap 48 is reversed upward and lifted upward, the seal lip 43 is pushed up by the hollow portion 483 coming into contact with the lower surface of the seal lip 43 . As a result, the seal lip 43 is bent at its base and its tip side is lifted up, separating it from the outer surface of the door crow. Therefore, the flocking 45 of the seal lip 43 prevents water from adhering to the outer surface of the door glass.

In addition, since a hollow part 483 is provided in the draining blade 48, it is easy to reverse the door glass when going up and down, and the door glass 2
The resistance to lifting and lowering can be reduced. In addition,
The flocking 45 on the lower side of the draining blade 48 may not necessarily be provided, but due to variations in the installation of the door glass 2, it may be located outside the door glass 2, that is, the weather strip 4 (
When it approaches pj, it prevents the outer surface of the door crow from being pressed directly against the lower side surface of the hollow portion 483, and serves to alleviate sliding resistance.

In this embodiment, only the front half of the door glass, which is necessary for backward visibility using the door mirror 3, is wiped with the draining blade 48, but if the draining blade 4 is installed along the entire length of the Unisa strip, the entire surface of the glass can be wiped. can. Further, the draining blade 48 is not limited to being fitted onto the mounting base 41 by means of the bolt 46, but may be fixed to the mounting base 41 by means such as adhesive. The weather strip of the present invention can also be applied to rear doors.
