Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a weatherstrip of an automobile which is fitted to the periphery of a window glass which is fixed to an opening of a vehicle body in a state of being killed, and which maintains a sealing property in a vehicle interior. About.

[Conventional technology]

Weatherstrips of the type described above that are fitted to windowpanes, such as front and back window panes of automobiles, are well known in the art.

FIG. 3 shows an example, in which a window glass 3 is immovably arranged in an opening formed in a back panel 2 constituting a vehicle body (cab in this example) 1 of a truck, and a weather strip 4 is fitted around the periphery thereof. ing. The weather strip 4 extends along the periphery of the window glass 3 and is made of an elastic material such as rubber or a soft synthetic resin.

FIG. 4 is a cross-sectional view taken along the line IV-IV of FIG. 3, showing a related configuration of the conventional weatherstrip 4, the vehicle body 1, and the window glass 3. As can be seen from this figure, a glass fitting groove 5 and a flange fitting groove 6 are formed in the weather strip 4 over its entire length, and the former glass fitting groove 5 fits around the periphery of the window glass 3. The latter flange fitting groove 6 is fitted in a vehicle body flange portion 7 defining an opening of the vehicle body, and the vehicle body flange portion 7 is located substantially parallel to the window glass 3. Window glass 3
Is fixed to the vehicle body 1 via the weather strip 4 in this manner.

The weatherstrip 4 further has an outer lip 8 and an inner lip 9 whose tips are spaced apart from each other. As shown in FIG. I have. Also, when the weather strip 4 is mounted on the vehicle body 1 as shown in FIG. 4, the outer lip 8 comes into close contact with the vehicle body outer surface, in this example, the outer surface of the back panel 2. Similarly, when the weather strip 4 is mounted on the vehicle body 1, the inner lip 9 is located closer to the vehicle interior I than the outer lip 8 and is in close contact with the vehicle body surface between the vehicle body outer surface and the vehicle body flange portion 7. , So that its tip faces the outer lip 8. In this way, the sealing performance of the vehicle interior I is enhanced.

In order to further enhance the above-mentioned sealing performance, a sealer 10 is filled in a concave groove defined by the outer lip 8, the inner lip 9, and the vehicle body surface. When assembling the window glass 3 to the vehicle body 1, the sealer 10 is filled as follows.

As shown in FIG. 5, prior to attaching the window glass 3 on which the weather strip 4 has already been fitted to the vehicle body 1,
A sealer (not shown) inserts a sealer 10 into a groove between the outer lip 8 and the inner lip 9 whose tips are separated from each other.
Inject. Next, as shown in FIG. 4, the flange fitting groove 6 of the weather strip 4 is fitted to the vehicle body flange portion 7,
The window glass 3 is assembled to the vehicle body 1. At this time, the inner lip 9 strikes the surface of the vehicle body 1 and is deformed as shown by an arrow A in FIG. For this reason, a part of the sealer 10 accommodated in the groove between the lips 8 and 9 may protrude, and this may adhere to the surface of the vehicle body 1 as indicated by reference numeral 10a in FIG. . It is necessary to wipe off the sealer 10a thus adhered, but such a work is very troublesome and inevitably causes a problem of reducing the production efficiency of the automobile.

Therefore, as shown in FIG.
Two inner lips 9a and 9b are protruded, and a small chamber 11 for filling the sealer is formed by these inner lips, and a tip nozzle of a sealer gun (not shown) is attached to the small chamber 11 before assembling the window glass 3. Then, the sealer 10 is filled and the sealer 10 is confined in the small chamber 11, and then the weather strip 4 and the window glass 3 are assembled to the vehicle body 1 as shown in FIG. 7, and the inner lips 9a and 9b are crushed. There has been proposed a configuration in which the sealer 10 is deformed to flow out between the surface of the vehicle body 1 and the weatherstrip 4 and is filled (see, for example, Japanese Utility Model Publication No. 53-5693).

However, according to this configuration, as is apparent from FIG. 6, the tips of the two inner lips 9a, 9b are elastically pressed against each other to form the small chamber 11, so that when the sealer is filled here, It is necessary to turn the inner nozzles 9a and 9b so that the tip nozzle of the sealer gun enters the small chamber 11. Such work is very troublesome, and the work efficiency must be reduced.

When the small chamber 11 is filled with the sealer 10, the inner lips 9a and 9b other than the part into which the tip nozzle of the sealer gun protrudes are closed by pressing their ends against each other.
The sealer 10 injected into the chamber 11 cannot be seen from the outside, and the operator cannot immediately judge how much the sealer 10 has been filled into the small chamber 11, and the amount of the filled sealer 10 is too small or conversely large. There is a risk that the sealer 10 will protrude from the small room 11 too much.

Furthermore, the compartment 11 is delimited by two inner lips 9a, 9b, so that its volume is substantially constant,
The amount of sealer 10 that can be injected into 11 is also constant. On the other hand, it is generally unavoidable that the opening of the vehicle body to which the window glass 3 is attached becomes somewhat larger or smaller due to variations during the manufacture of the vehicle body. When the opening of the vehicle body is formed large for such a reason, it is necessary to increase the filling amount of the sealer 10 to prevent a gap from being formed between the weather strip 4 and the surface of the vehicle body 1. However, both inner lips
Since the amount of the sealer 10 that can be injected into the small chamber 11 in 9a and 9b is almost constant as described above, when the vehicle body opening is large,
It is difficult to increase the filling amount of the sealer in response to this.

[Problems to be solved by the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a weatherstrip for an automobile, which solves the above-mentioned conventional problems at once.

[Means for solving the problem]

In order to achieve the above object, the present invention provides a glass fitting groove fitted to the periphery of a window glass and a vehicle body flange portion which defines an opening of a vehicle body and is located substantially parallel to the window glass. A flange fitting groove, an outer lip which is in close contact with the outer surface of the vehicle body when mounted on the vehicle body, and which is located on the inner side of the outer lip when the vehicle is mounted on the vehicle body, and wherein the outer surface of the vehicle body and the vehicle body flange portion And an inner lip that is bent so that the tip is directed toward the outer lip side, the tips of the outer lip and the inner lip are separated from each other, and a concave groove is defined by both lips. In a weather strip of an automobile, a sealer is injected before the weather strip is mounted on the vehicle body, and the injected sealer is pushed out into the concave groove in a state where the weather strip is mounted on the vehicle body. As described above, the sealer groove crushed by the bending of the inner lip closely contacting the vehicle body surface between the vehicle body outer surface and the vehicle body flange portion is provided on the inner lip base between the outer lip and the inner lip, and on the concave groove. A weather strip characterized by being formed continuously is proposed.

〔Example〕

 Hereinafter, the present invention will be described based on illustrated embodiments.

The appearance when the weather strip in this example is fitted to the window glass and attached to the vehicle body is not different from that of FIG. 3, and the basic form of the weather strip is also the conventional weather strip shown in FIG. No difference from the strip. Therefore, in FIG. 1 and FIG. 2 showing the embodiment of the present invention, the same portions as those in the related art are shown in FIG.
The same reference numerals are given to the respective parts in the figure, and the description of the same parts is omitted. FIG. 3 will be referred to as needed.

FIG. 1 is a sectional view similar to FIG. 4, showing the weather strip 4 of the present embodiment. FIGS. 2 (a) and 2 (b) show the case where the weather strip 4 and the window glass 3 are assembled to the vehicle body 1. It is sectional drawing.

As shown in FIG. 2 (a), the weather strip 4 of the present embodiment has a sealer groove 20 into which a sealer 10 is injected before the weather strip 4 is mounted on the vehicle body 1, and an outer lip having a tip separated from each other. Inner lip 9 between 8 and inner lip 9
And the sealer groove 20 is formed continuously with the concave groove defined by the outer lip 8 and the inner lip 9. Only the structure of the sealer groove 20 is different from the conventional weatherstrip shown in FIG. 4, and the other structures are substantially the same.

As shown in FIG. 2 (a), before assembling the window glass 3 on which the weatherstrip 4 is fitted to the vehicle body 1, the outer lip 8 and the inner lip 9 are moved by a sealer gun (not shown). Inject sealer 10 into This is also the same as the conventional case, but at this time, the sealer 10 is deeply injected into the sealer groove 20. For this reason, the sealer 10 does not exist near the tip openings of the outer lip 8 and the inner lip 9, and accordingly, the window glass 3
2B, the weatherstrip 4 is brought into contact with the vehicle body 1 as shown in FIG. 2 (b).
Does not protrude from between the lips 8,9. Therefore,
As shown in FIG. 5, there is no problem that the sealer 10 adheres to the outer surface of the vehicle body and stains it.

When the weather strip 4 is mounted on the vehicle body 1 as shown in FIGS. 1 and 3, the inner lip 9 that is in close contact with the vehicle body surface between the vehicle body outer surface where the outer lip 8 is in close contact and the vehicle body flange 7 is bent. As a result, the sealer groove 20 is crushed, and the sealer 10 injected into the sealer groove 20 is
And the sealer 10 is filled between the weather strip 4 and the vehicle body surface. When the weather strip 4 is mounted on the vehicle body 1 as described above, the sealer groove 20 is crushed by the bending of the inner lip 9, and the sealer 10 housed therein is pushed out into the concave groove between the inner lip 9 and the outer lip 8. Therefore, the sealer 10 can reliably and reliably perform its original function, that is, the function of enhancing the sealing performance of the vehicle interior I.

As described above, according to the weather strip of this embodiment, it is possible to prevent the sealer from adhering to the exterior surface of the vehicle body seen from the outside and contaminating the outer surface. However, as shown in FIG. At the time of injection, the tips of the outer lip 8 and the inner lip 9 are separated from each other, and the both lips 8, 9 are open. Therefore, it is possible to easily insert the tip nozzle of the sealer gun into this opening to perform the injection operation of the sealer. it can. In addition, since the injected sealer can be seen by the operator, the sealer groove 20
In this case, an appropriate amount of the sealer 10 can be injected, and a problem that the injection amount is too large or too small can be prevented.

Further, even when the opening of the vehicle body is formed relatively large due to a variation in the manufacture of the vehicle body, a large amount of sealer can be injected into the concave groove between the outer lip 8 and the inner lip 9, so that the conventional example shown in FIG. In addition, it is possible to prevent a problem that causes the sealer to be insufficiently filled.

In order to fit the flange fitting groove 6 of the weather strip into the vehicle body flange portion 7, a string is inserted through the fitting groove 6 in advance, and the fitting groove 6 is inserted into the vehicle body flange portion 7 while pulling out the string. Although it is normal to fit the cable, the string is not shown in FIGS. 2 (a), (b), 5 and 6.

The present invention is naturally applicable not only to a weatherstrip for a window glass attached to a back panel of a truck but also to a weatherstrip for a window glass such as a front window and a side window of a general automobile.

[Effect of the invention]

According to the present invention, at the time of assembling the window glass, it is possible to prevent the sealer injected into the weather strip from adhering to the outer surface of the vehicle body, to enhance the workability when the sealer is injected into the weather strip, and to set an appropriate amount of the sealer. Can be injected. Moreover, even if the size of the vehicle body opening varies, a corresponding amount of sealer can be filled between the vehicle body and the weather strip. Also, when the weather strip is mounted on the vehicle body, the sealer groove is crushed by the bending of the inner lip, and the sealer housed therein is pushed out between the inner lip and the outer lip, so that the sealer has its original function, that is, the inside of the vehicle, The function of enhancing the sealing performance of the device can be reliably and reliably performed.
