Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a door weather strip that is attached to the outer periphery of a door and provides a barrier between the door and a vehicle body opening for attaching the door.

Conventionally, as shown in FIG. 1, a hole between a door 2 of an automobile 1 and an opening 4 formed on the side of a parking lot 3 for attaching the door 2 has been covered with a covering material on the outer periphery of the door 2. There is a door weather strip 5 that uses a door weather strip. For example, as shown in FIG. 2, the door weather strip 5 includes a mounting base 5a that is formed on the door sill 6 or fitted to the taker 7, and a mounting base 5a that protrudes from the mounting base 5a and is attached to the door 2 when the door 2 is closed. Sometimes the tip comes into close contact with the periphery of the vehicle body opening 4/-
It is equipped with a lip 5b. In the figure, the seal lip 5b is composed of a main lip 5c and an outer lip 5d, and both the main and outer lips 5c and 5d form a double seal structure.

However, when assembling the vehicle body 3, when assembling the door 2, the door 2 is installed slightly vertically relative to the opening 4 due to slight formation errors and assembly errors. Therefore, if Door 2 is lowered and disappears, Shima 3 (A)
As shown in FIG. 2, the outer 11 protrusion 5d does not come into contact with the closing edge of the opening 41, resulting in poor lubrication. On the other hand, door 2
The movement of the rising edge 2.1 is the rabbit, and the main lip 5C is shown in Figure 3 (Bl).

Outer lip 5d is open [1Htt (heavy I+<
Because it does not press, the reaction force cam due to the knoll lip 5b
One of the problems is that the hunting of the door 2 is bad.

The present invention takes advantage of the conventional 38 points, and provides a hollow main body that comes into close contact with the solid edge of the front vehicle body l11r1 part when the door is closed, and whose outer rim retracts inward when pressed against the periphery of the opening. lip, and the tip protruding from the outer base end of this main lip is oriented toward the main lip, and the door 1
The pressing lip that presses against the outside of the main 11 knob that is bent outward when playing base is shaped like h? By doing this, the main lip can always come into contact with the periphery of the opening even if the door is bent down, and the pressing force of the main lip by the front pressing lip can be applied when the door is closed. By setting the IF 81 in advance to a certain degree, the above-mentioned suppression lip can be reduced without having to adopt a double loop structure.
+fl ii By pressing the main lip by itself, it is possible to ensure sufficient lurability of the main lip.

Hereinafter, one embodiment of the present invention will be described based on the drawings. still,
In describing this embodiment, the same parts as those in the conventional structure will be designated by the same reference numerals.

That is, FIG. 4 shows the door weather strip IO of the present invention, and 7 is a retainer formed on the outer periphery of the can/unit 6. As shown in FIG. The door weather strip 1o has a mounting base 1 which is fitted into the retainer 7, and this mounting base 11
A hollow main lip 12 is provided so as to project from the main lip 12 so as to be slightly inclined toward the interior X of the vehicle interior. This main lip 1
2 When the door is closed, it is in close contact with the periphery of the monolithic opening 4, and when pressed by the internuclear [1 part 4 periphery], the outside (Ill wall 12
B is designed to be recessed inward of the hollow portion 12b.

In the direction and final application 11, a concave groove-shaped bent portion 13 extending in the length direction of the weather strip 10 is formed at the front it"', 9L, side tl, and % 12a, and this hole 1 bends. Part 13 to 1 tttl
s12 & is easy to invaginate and always has a fixed shape. Further, from the outer base end 12c of the main lip 12, the opening 4 is opened when the door is closed.
The main lip 12 is pressed against the periphery and bent outward.
A pressing lip 14 is provided protruding from the 91 side of the holder, the tip of which presses into contact with the 91 side. In other words, this pressing lip 14 has a base 14a protruding from the side base end 12c in the radial direction outside the path, and extends from the tip of the first part 148 to the main lip for 11 years.
A suppressing portion 14 tl is provided protruding in a substantially inverted shape and oriented in two directions.

By the way, the peripheral edge of the vehicle body opening 4 generally has a horizontal l54b that slopes slightly upward inward from the outer end 4B, and a hanging portion 4C that is bent downward from this horizontal portion 4b. Twelve iL1 main lips are brought into contact with the vertical portion 4C.

According to the above configuration, when closing the door, the main lip 12 is attached to the vertical portion 4 of the vehicle body opening edge 4 immediately before the door is closed.
C, and bends outward as the door is rotated to close. At this time, the front δe main 1/outer wall 12 & of the protrusion 12 invades inward from the bent part 13 to the hollow part 12 b as shown by the solid line in FIG. 'Let the main lip fall in the direction of 12. In this way, press FEII knob 14 or main 1.
”By falling down in the direction of Tsubu+2, the suppression lip 1
The pressing force of 4 can be increased. When the door is completely closed, the main lip I2 is completely in close contact with the front vertical portion 4C, as indicated by the broken line in FIG. , IJ, the main lip 12 is bent so that the tip of the suppression lip 14 comes into suppressive contact with the outer IJ12& of the main lip 12. At this time, the pressing lip 14 is pressed by the main lip 12 and -
H main lip 12 direction 41) From the inserted state
f It was in a state where it was raised outward. in this way,
In the door weather strip 10 of this embodiment, the main lip t2 is pressed from the outside by the press 11 knob 14, and the main lip 12 is pressed against the periphery of the inter-vehicle body part 4 to ensure that the 7-ru is applied. However, even if the double layer structure is not removed, the layer properties will not deteriorate. ``It goes without saying that the pressing force of the pushing king lip 14 is set to such an extent that it does not prevent the door from being closed when the door is closed.Also, the main lip 12 is placed in contact with the vertical portion 4C of the opening edge 4 of the vehicle body. Since they are in contact with each other, even if the door is slightly shifted in the vertical direction due to an assembly error, the knollability will not deteriorate.

Figure 6 shows the door hinge (not shown) located at the outer periphery. =Ir Door weather l It abuts against the edge 4 and has a double 7-rule structure.

FIG. 7 shows another embodiment of the present invention, in which the pressing lip 14 is extended so as to form two forks with the tip, which is the suppressing part, of the main lip 12, and the extended end WS is used to close the door. At the same time, it is brought into contact with the periphery of the 1'' portion 4 between the vehicle bodies. As shown in Figure 4 above, the 1,4 clouding is the pressure lip 1.
4 is formed by an 8 part 14'a and a suppressing part 141) which bends and protrudes from the tip of this base part 14a, but in this case, the front ftr, the base part 14
8 is further provided 911; and brought into contact with the horizontal portion 4b of the portion 4 between the vehicle bodies. Therefore, this fly installation part 14c and the pressing force 14b have a bifurcated shape.By bringing the extension part 140'6 into contact with the 4th circumference of the vehicle body opening in this way, the main lip 12 In this case, a double)-ru structure can be formed, and /-ru・)・11 can be greatly increased.

s #jJ i('', when the pill installation part 14 Q enters the quadruple horizontal part of the vehicle body opening 4, the outer end 4a of the horizontal part 4bθ) is slightly curved F. Nevertheless, due to the request P (FIG. 8) when the door is closed and the main lip 12's 〃] (the husk of the pressing lip 14 when the door is closed), the main lip 12 is placed in a predetermined position without being obstructed by the outer end 4a. Ru.

In other words, the trajectory P is drawn such that the door moves diagonally upward just before the door is closed, and when the suppression lip 14 is bent, the main lip 12 moves as shown by the solid line in FIG.
The outer wall 12 of the main lip 12 is in contact with the pressing lip 14 after it comes into contact with the vehicle body opening part 4
By causing the suppression lip 14 to fall down due to the intrusion of a, the sail installation portion 14C will not interfere with the outer end of the vehicle body opening 4 and will not be obstructed.

As explained above, in the door weather strip for a #IJJ vehicle of the present invention, when the door is closed, the outer wall comes into close contact with the periphery of the vehicle body opening, and when pressed by the periphery of the auxiliary opening, the outer wall collapses inward. A hollow main lip is inserted into the main lip, and the outer end protrudes from the outer base end of the main lip, and the outer end thereof is oriented toward the main lip and presses into contact with the outer side of the main lip that is bent outward when the door is closed. Since the main lip is formed with a suppression lip, even when the door is installed with a vertical deviation, the main lip can always come into contact with the periphery of the opening, and by pressing the main lip with the suppression lip, 0, which has the excellent effect of ensuring sufficient sealing performance of the main lip.
