Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a roof molding mounting structure for an automobile.

[0002]

[Prior art]

 Conventionally, a groove is formed in the joint between the roof panel and the roof side panel at both widthwise ends of the roof panel of an automobile, and a roof molding is fitted in this groove to improve the appearance of the joint. Often. For example, as described in Japanese Utility Model Laid-Open No. 60-45155, a groove is formed along the joint between the roof panel and the roof side panel, and one end of the panel extends vertically from the groove bottom surface. There is a type in which a flange extending to the front is formed and a roof molding is attached through a plurality of clips provided on the flange. According to this, it is possible to easily perform the work of mounting the roof molding, and it is possible to firmly mount the molding over the entire length of the molding. However, in the roof molding mounting structure described above, the cost is increased because the panel molding is complicated by providing the flange in the concave groove and a large number of clips are used. Further, in order to solve these problems, as described in Japanese Utility Model Laid-Open No. 61-165882, a groove is formed along the joint between the roof panel and the roof side panel, and the opening of the groove is formed at the bottom. There is a narrow groove that is narrower than the groove width, and a roof molding is fitted in this groove and both ends of the roof molding are bonded to the bottom of the groove. According to this, the middle portion of the roof molding can be prevented from coming off due to the shape of the concave groove, and since it is not necessary to provide a coupling means to the concave groove of the middle portion, the mounting structure can be simplified and the number of parts can be reduced. However, in this roof molding mounting structure, the strength of the middle portion of the roof molding is weak, and there is a risk that the roof molding may come off the groove. Further, it is necessary to press-form the side wall of the groove and the outer surface of the roof panel that is continuous with the groove at a negative angle, and there is a problem that sufficient cost reduction cannot be achieved.

[0003]

[Problems to be solved by the device]

 As described above, the present invention provides a roof molding mounting structure that enables reliable and inexpensive mounting of the roof molding in the groove formed in the joint between the roof panel and the roof side panel. The purpose is to do.

[0004]

[Means for Solving the Problems]

 That is, according to the present invention, in a roof molding mounting structure in which front and rear concave grooves are formed at both widthwise ends of a roof panel, and the roof molding is mounted in the concave grooves, the roof molding is made of an elastic material and the molding body is made of elastic material. It is composed of joints formed at both ends of the molding body, and joints corresponding to both joints are formed at both ends of the concave groove, and the distance between both joints is shorter than the distance between both joints. This is a structure for mounting the roof molding of a car characterized by the above.

[0005]

[Action and effect]

 According to the above configuration of the present invention, the molding body is made of an elastic body, and the distance between the joint portions formed on the roof molding is shorter than the distance between the joint portions formed in the concave groove. When the molds are connected to both parts to be joined, the molding body is stretched, and as a reaction force, a large contraction force is generated, which causes the roof molding to be pressed toward the bottom surface of the groove formed in the roof panel. Installed as required. Therefore, in the present invention, it is possible to prevent disengagement from the concave groove without providing a mounting member such as a clip in the middle portion of the roof molding, and it is not necessary to form a negative angle press molding of the flange or the concave groove side wall on the roof panel. This makes it possible to mount the roof molding inexpensively and reliably.

【Example】

 Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 and 2, reference numeral 1 is a roof panel that constitutes the outer surface of the roof of the vehicle body, and 2 is a roof side panel that constitutes the side surface of the vehicle body. 3 is formed, and the roof molding 4 is fitted into the groove 3. As shown in FIG. 3, the roof molding 4 is composed of a molding main body 5 formed by extrusion molding of an elastic material (for example, ethylene propylene) and end pieces 6 and 6 vulcanized and bonded to both ends thereof. A drainage groove 7 is formed on the upper surface of 4. Then, bolts 8 and 8 (joint portions) having flat plates welded to the heads are embedded in the end pieces 6 and 6, and the bolts 8 and 8 are inserted into the bottom surfaces of both ends of the groove 3. Bolt holes 9 and 9 (joined portion) are formed. FIG. 4 shows the length relationship between the bolts 8 and 8 and the bolt holes 9 and 9 in the natural state of the roof molding 4, and the length A between the bolts 8 and 8 is the length between the bolt holes 9 and 9. It is shorter than B, and in this embodiment, A is formed to be 1 to 2% shorter than B. The joints of the respective edges of the roof panel 1 and the roof side panel 2 are sealed with a seal material 10, and the lower surface of the joints is provided with a roof inner panel provided inside the roof side panel 2. The inner edge of the panel 11 is polymerized and joined, and the roof side panel and the roof inner panel form a closed cross-section structure. In the above structure, when the roof molding 4 is attached to the groove 3, first, the molding main body 5 is elastically extended and the bolts 8 and 8 are inserted into the bolt holes 9 and 9. In this state, the roof molding 4 is temporarily joined to the groove 3 and fastened from the inside of the vehicle body by the nut 12. Therefore, the roof molding 4 is attached so as to be slightly pressed by the contracting force of the extended molding body 5 into the concave groove 3 having a convex curved surface in the vehicle front-rear direction, so that a clip or the like is attached to the middle portion of the roof molding. Even if no member is provided, it can be prevented from coming off the concave groove. Further, it is not necessary to process a flange or the like on the end portion of the roof panel, which does not increase the cost. Further, since the molding body 5 is formed of an elastic material, it is possible to absorb a processing error between the bolt holes 9 and the molding error of the roof molding itself, which is advantageous in quality control.

FIG. 5 shows another embodiment, and the same parts as those of the above-mentioned embodiment are designated by the same reference numerals for description. Pins 13 (joined portions) are welded to both ends of the groove 3, and the pin 13 has a shaft portion to be welded and a large-diameter head portion formed at its upper end. The end piece 6 of the roof molding 4 is formed with a pin hole 14 (coupling portion) that fits into the pin 13, and the pin hole 14 receives the elastic force of the molding body 5 so that the shaft of the pin 13 can be received. A flat plate 15 that is in contact with the portion is embedded. In this embodiment, the mounting of the roof molding 4 is completed by fitting the pin hole 14 of the end piece 6 into the pin 13 provided in the concave groove, so that the mounting work from the vehicle interior side becomes unnecessary, Installation workability is improved.

The roof molding mounting structure of the present invention is not limited to the structure of this embodiment, and the end piece is fixed to the bottom surface of the groove, for example, the end piece is attached to the groove by a clip or the like. Any material may be used, and the material of the molding body may be an elastic material having weather resistance.
