Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a weatherstrip that is attached to a door frame of a vehicle and seals between a door and a vehicle body opening, and in particular, improves workability of insertion when the attachment base is inserted into and fitted to a retainer on the periphery of the door frame. Car weather strips.

[0002]

[Prior art]

 Among weather strips for automobiles, the weather strip, which is interposed between the door frame above the door and the body panel on the vehicle body side, is a door that is frequently opened and closed, and is exposed to negative pressure during high-speed traveling. Since the part where the gap is most likely to change due to the suction phenomenon is sealed, a high level of sealing performance is required to completely prevent the entry of wind and rain, water or noise during car washing from this part. Therefore, in a conventional automobile, for example, as shown in FIG. 4, the hollow mounting base 3 fitted to the retainer 2 attached to the periphery of the door frame 15 of the automobile is brought into contact with the body panel 16 of the vehicle body. A weather strip 1 having a seal structure in which a hollow main seal portion 9 and a sub lip 10 that engages with a part of the door frame 15 are integrally formed is generally used.

By the way, when attaching this type of weatherstrip to the retainer attached to the periphery of the door frame, as shown in FIG. 5, the bottom of the weatherstrip 1 on the passenger compartment side is inserted, and then the roller is inserted. A method of pressing in the direction of the arrow with a jig or tool is generally adopted.

[0004]

[Problems to be solved by the device]

 In the weather strip having the conventional structure as described above, in order to provide the weather strip 1 with appropriate rigidity and reaction force, the thickness of the vehicle outer side column 5 of the hollow mounting base 3 is set to the vehicle inner column 4 Since it is formed relatively thicker than the other parts except for, and has a uniform thickness over its entire length, it is projected on the support column 5 when it is fitted to the retainer 2 by pressing with a jig or tool such as a roller. There is a drawback in that workability at the time of insertion is poor, because a force for pushing and bending the vehicle outer side support 5 is required until the retaining rib 11 passes through the hook-shaped edge portion 14 of the retainer 2.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a novel hollow attachment base portion of a weather strip having a hollow attachment base portion fitted to a retainer. By finding the configuration, we will provide a weather strip for automobiles that does not require extra force for fitting to the retainer, facilitates installation work, and can exhibit a sealing function comparable to conventional products. is there.

[0006]

[Means for Solving the Problems]

 Accordingly, the feature of the automotive weather strip of the present invention that meets the above-mentioned object is that in a weather strip having a hollow mounting base fitted to a retainer at the peripheral edge of a door frame, the outer side portion of the hollow mounting base is located outside the vehicle. A thin groove portion is provided at the intersection by forming a notch groove in the longitudinal direction on the inner surface of the intersection of the column and the lateral bar that contacts the bottom surface of the retainer.

The structure of the seal portion of the weather strip according to the present invention is not particularly limited, and the weather strip and the main seal having a main seal portion which is integrally formed with the hollow mounting base portion and contacts the body panel on the vehicle body side. A double-seal structure weatherstrip having a portion and a sub-lip that abuts a drip molding above the vehicle body is applicable, but in particular, in the present invention, it is fitted to a retainer on the periphery of the door frame. A hollow main mounting part and a hollow main seal part that is connected to the upper ends of the vehicle inner side columns of the mounting base and is inclined to the outer side of the vehicle and abuts the body panel on the vehicle body. A horizontal top surface is extended to the outside of the vehicle from a corner portion that intersects with the vehicle outer side pillars of the mounting base, and a sub-lip that engages with a part of the door frame is provided. In the weather strip, a longitudinal cutout groove is formed on the inner surface of the intersection of the vehicle outer side column of the hollow mounting base and the horizontal bar in contact with the bottom of the retainer, and a thin wall portion is provided at the intersection. An automotive weatherstrip is provided as a preferred example.

[0008]

[Action]

 In the weather strip of the present invention having the above-mentioned structure, when the hollow mounting base is fitted to the retainer, the thin wall becomes a bending point at the intersection of the vehicle outer side strut that receives an insertion load and the horizontal bar that contacts the bottom surface of the retainer. Since the portion is installed, the side strut can be bent inward with a comparatively small pressing force as compared with the conventional weather strip. As a result, the retaining rib projectingly provided on the column can easily pass through the hook-shaped edge portion of the retainer, and the mounting workability is improved.

【Example】

 Hereinafter, the features of the automobile waste strip of the embodiment of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a cross-sectional view showing a weather strip according to an embodiment of the present invention fitted to a retainer at the periphery of a door frame of an automobile. The weather strip 1 is a hollow fit to a retainer 2 at the periphery of a door frame of an automobile. -Shaped mounting base 3 and a hollow main seal portion 9 that is provided on a side face 6 that is connected to the upper ends of the vehicle-inside side columns 4 of the mounting base 3 and is inclined toward the outside of the vehicle, and that abuts on a body panel on the vehicle body side A substantially horizontal top surface 7 connected to 6 is extended to the outside of the vehicle from a corner portion of the attachment base 3 that intersects with the vehicle outer side support column 5 and integrally includes a sub lip 10 that engages with a part of the door frame. The above-mentioned vehicle outer side support column 5 is provided with a retaining rib 11 on the lower outer surface thereof, and a longitudinal cut is formed on the inner surface of the intersection of the same side support column 5 and the horizontal bar 8 in contact with the bottom surface of the retainer. Notch groove 12 is formed and a thin portion 13 is provided.

FIGS. 2 and 3 are explanatory views showing a process of inserting the weather strip 1 of the present invention into the retainer 2. As described above, according to the present invention, when the insertion load in the direction of the arrow is applied by a jig or tool such as a roller, the vehicle outer side support column 5 is relatively easily bent from the thin portion 13 to the inner side. The retaining ribs 11 can easily pass through the hook-shaped edge portion 14 of the retainer 2, eliminating the need for extra pressing force at the time of mounting and damaging the weather strip body such as the tips of the retaining ribs 11. No worries, insertability is improved. In this case, except that the thin portion 13 is provided, no special design change is required in the structure of the weather strip 1 and the retainer 2, so that the production can be performed only by changing the extrusion die in the extrusion molding method. In addition, the weather strip has qualitative functions such as sealability comparable to conventional products.

[0012]

[Effect of device]

 As described above, the automotive weather strip of the present invention has a thin-walled portion that becomes a bending point at the intersection of the vehicle outer side column that constitutes the hollow mounting base of the weather strip and the lateral bar that contacts the bottom surface of the retainer. Since it is equipped with a retainer on the periphery of the door frame, no extra pressing force is required, the installation work is easy, there is no fear of damaging the weather strip body, and the function is not inferior to conventional products. It has an excellent effect of being able to exert the effect.
