Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a structure for preventing a shift of a door weather strip by fixing an insert member embedded in a door weather strip that seals a gap between a door sash and a vehicle body (body) to the door sash.
[0002]
[Prior art]
As shown in FIGS. 4 and 5, door weather strips 5 and 6 are provided at the periphery of the door sashes 3 and 4 of the front door 1 and the rear door 2 of the vehicle to seal the gap between the door sashes 3 and 4 and the vehicle body (body). Although the door weather strips 5 and 6 are pulled to the rear side of the vehicle due to an impact when the front door 1 or the rear door 2 is opened and closed, the door sashes 3 and 4 are partially displaced. There is a problem that the sealing performance is deteriorated or the appearance is deteriorated due to separation. Conventionally, in order to prevent this deviation, an insert member 7 is embedded in a corner portion of the door weather strips 5 and 6 and the insert member 7 is fixed to the door sash 3 with a clip 8 as shown in FIGS. It is known.
[0003]
According to this, the displacement of the insert member 7 in the horizontal direction (the left-right direction in FIG. 6 and the direction perpendicular to the paper surface) and lifting (up-down direction in FIG. 6) are prevented.
The door weather strip 5 includes an attachment base portion 5a attached to the door sash 3, a seal portion 5b formed integrally therewith, and a lip portion 5c that elastically contacts the periphery of the vehicle body opening. The door weather strip 6 has the same configuration as the door weather strip 5.
[0004]
[Problems to be solved by the invention]
However, since it is necessary to form the space 9 for inserting the clip 8 as shown in FIG. 6, there is a problem that extra work such as bending and punching of the door sash 3a must be performed.
Further, since the insert member 7 is fixed via the rubber weather strip 5, the fixing force is not sufficient. Furthermore, since the weatherstrip 5 and the door sash 3 are thereby perforated, there is a problem that water enters from the gap between the hole and the clip 8.
[0005]
On the other hand, in the straight portion of the weather strip 5, there is one in which the stud 11 is fitted in the embedded insert member 10 as shown in FIG. 8 to prevent the horizontal displacement in FIG. 8, but at the same time the vertical direction in FIG. This is insufficient because it is impossible to prevent misalignment.
[0006]
SUMMARY OF THE INVENTION An object of the present invention is to provide a door weather strip misalignment prevention structure that is easy to mount and excellent in fixing force of an insert member to a door sash.
[0007]
Another object of the present invention is to provide a door weather strip slip prevention structure that prevents water from entering.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, the door weather strip slip prevention structure of the present invention is formed integrally with a seal portion that elastically contacts the periphery of the vehicle body opening, and is embedded in a corner portion of the door weather strip attached to the door sash. In the door weather strip misalignment prevention structure that fixes the insert member to the corner portion of the door sash, a stud member that is substantially perpendicular to the door sash and whose tip is fixed to the door sash is provided, and the stud member is provided from the periphery. The covering substantially cylindrical frame portion is formed on the insert member, and the head portion of the stud member is brought into contact with the inner surface of the substantially cylindrical frame portion.
[0009]
Further, in the invention according to claim 1, a locking claw portion is formed on the inner side of the substantially cylindrical frame portion to lock the head portion of the stud member and prevent the displacement of the insert member with respect to the direction in which the stud member extends. (Claim 2).
[0010]
According to the first aspect of the present invention, the substantially cylindrical frame portion that covers the stud member from the periphery is provided at the corner portion of the door weather strip so that the head portion of the stud member is brought into contact with the inner surface of the substantially cylindrical frame portion. Since it is formed in the embedded insert member, displacement of the insert member in the direction perpendicular to the direction in which the stud member extends is prevented. By simply covering the stud member with the substantially cylindrical frame, the insert member is firmly fixed to the door sash and, in addition, the door sash is not particularly bent or perforated, so installation is easy. Therefore, the ingress of rainwater and washing water is also prevented.
[0011]
According to the second aspect of the present invention, the displacement of the insert member relative to the direction in which the stud member extends, that is, the lift of the insert member, is prevented by engaging the head of the stud member inside the substantially cylindrical frame portion. Since the locking claw is formed, the insert member is further firmly fixed to the door sash.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described with reference to the drawings. In addition, the same code | symbol was attached | subjected to the part same as a prior art example.
FIG. 1 is a sectional view showing a door weather strip misalignment preventing structure according to an embodiment of the present invention, and FIG. 2 is an external perspective view showing a corner portion of an insert member 17 shown in FIG. FIG. 1 corresponds to a cross-sectional view taken along line AA when the insert member 17 shown in FIG. 2 is embedded in the door weather strip 5 in place of the conventional insert member 7 shown in FIG.
[0013]
The door weather strip 5 is formed integrally with the attachment base 5a attached to the door sash 3, the attachment base 5a, and the hollow seal portion 5b elastically contacting the periphery of the vehicle body opening, and the attachment base 5a. Lip portion 5c.
[0014]
The corner portion of the insert member 17 embedded in the door weather strip 5 has a substantially cylindrical frame that covers the stud member 12 with its tip 12a fixed by welding substantially perpendicularly to the door sash 3 from the periphery. A portion 13 is formed. The stud member 12 may be fixed using an adhesive or the like.
The inner diameter of the lower side (insert member 17 side) of the substantially cylindrical frame 13 is equal to the diameter of the head 12b of the stud member 12. That is, the head portion 12 b of the stud member 12 is brought into contact with the inner surface of the substantially cylindrical frame portion 13.
Thereby, the position shift of the insert member 17 in the direction perpendicular to the direction in which the stud member 12 extends is prevented.
[0015]
Further, a locking claw portion 14 is formed inside the substantially cylindrical frame portion 13, and the locking claw portion 14 is locked to the head 12 b of the stud member 12 and is inserted in the direction in which the stud member 12 extends. The displacement of the member 17, that is, the floating of the insert member 17 is prevented. In addition, although the latching claw part 14 was provided in the substantially whole circumference inside the substantially cylindrical frame part 13, as long as it can prevent the insert member 17 from being lifted up, it may be provided partially. .
[0016]
In the embodiment of the present invention, the cutout portions 13a and 13b are provided in the substantially cylindrical frame portion 13, but the complete cutout portion is not provided as in the insert member 27 shown in FIG. A cylindrical frame portion 23 may be formed.
In the embodiment of the present invention, since the head portion 12b of the stud 12 is circular, the frame portion is formed in a substantially cylindrical shape so as to come into contact with the head portion 12b. Any shape can be used as long as the displacement can be regulated. Therefore, for example, if the head portion of the stud member is a quadrangle, the frame portion may be constituted by a hollow quadrangular prism that abuts on the frame portion.
Furthermore, the substantially cylindrical frame portion is formed at the corner portion of the door weather strip 5 so as to effectively prevent misalignment, but may be formed at a straight portion.
[0017]
【The invention's effect】
As described above, according to the first aspect of the present invention, since the insert member is firmly fixed to the door sash only by covering the stud member with the substantially cylindrical frame portion, it is perpendicular to the extending direction of the stud member. The displacement of the insert member in the direction is prevented. In addition, the door sash is not particularly required to be bent or perforated, so that it can be easily attached and rainwater and washing water can be prevented from entering.
[0018]
According to the second aspect of the present invention, since the head portion of the stud member is locked by the locking claw portion, displacement of the insert member with respect to the direction in which the stud member extends, that is, lifting of the insert member is prevented. Furthermore, the insert member is firmly fixed to the door sash.
