Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a mounting structure for attaching both ends of a staying wire for extending a ceiling sheet inside a roof panel of an automobile to a roof rail.

In the conventional mounting structure, as shown in FIG. 1, the retaining wire 1, which stretches the ceiling sheet 5 on the inside of the roof panel 4 through a suspension bag 6, is processed into a bow shape that follows the curved shape of the roof panel 4. At the same time, both ends 1a, 1a of the retaining wire 1 are bent outward, and a bot 7 serving as an engagement stopper is formed on the peripheral wall of each end 1a, 1a, and both ends with the bot 7 are bent. 1a and 1a are inserted into locking holes 3 and 3 formed laterally in the roof rails 2 and 2, which are disposed facing each other above both sides of the vehicle body, respectively, thereby securing both ends of the staying wire 1. The parts 1a and 1a were attached to the roof rail 2.

However, in the case of such a conventional structure, a process of bending the retaining wire 1 into a bow shape and a process of bending both ends 1a and 1a further outward are required, which requires a lot of work in terms of manufacturing process. In addition to requiring a lot of man-hours, there was also a problem in terms of installation work, as there was a risk that the retaining wire 1 would rotate downward about the locking hole 3 of the roof rail 2 as a fulcrum when the ceiling sheet 5 was stretched. In addition, in the case of the conventional mounting structure,
When the installation shown in FIG. 1 is completed, the bent bases 1b and 1b of both ends 1a and 1a of the staying wire 1 and the vicinity thereof will be in a state of protruding into the inside of the vehicle body.
It also had the disadvantage of unnecessarily narrowing the ceiling space inside the car.

The present invention was devised in view of the various problems of the conventional mounting structure, and includes extending an extension piece that bends inward at the upper end of the roof rail, and having a downward opening in the extension piece. The above-mentioned problem is effectively solved by drilling a locking hole and attaching both ends of a straight retaining wire to the locking hole from below via new clips. be.

Hereinafter, the present invention will be described in detail based on an illustrated embodiment. First, as shown in FIG. Extension pieces 12 each bent inward are extended at predetermined intervals, a locking hole 13 opening downward is bored in each extension piece 12, and a button is inserted at the end of the locking hole 13. However, both ends of a retaining wire having a linear overall shape are configured to be engaged from below via clips 14, which will be described later.

The clip 14 is integrally molded from synthetic resin, and specifically consists of a clip base 14A and an expandable body 14B as shown in FIGS. 3A, B, C, and D, with the former base 14A shown in the figure. As shown, one end side has a fitting hole 15 into which the end of a straight retaining wire is fitted, and the other end side is thin and divided into left and right sides by a central slit 16a for expansion on the upper surface of the other end side. It has a leg part 16 with an insertion hole 17 formed therein that communicates with the slit 16a, and a lock piece 18 with an engaging pawl 18a formed at the tip on the other end, which is vertically disposed, This is a configuration in which a tapered enlarged diameter surface 17a is formed on the opposing inner wall surface of the hole 17. On the other hand, the latter expandable body 14B includes an insertion portion 19 inserted into the insertion hole 17 from below and a pressing piece portion 2 integrally provided at the lower end of the insertion portion 19.
0, and the insertion portion 19 has projections 19a formed on its wall surface to engage with the slit 16a.

Clip base 14A and expansion body 14B having such configurations
This relationship is such that both projections 19a of the insertion portion 19 of the expandable body 14B are aligned with the tapered enlarged diameter surface 17a of the insertion hole 17, and the insertion portion 19 is rotated until each projection 19a engages in the slit 16a. By tentatively inserting it into the insertion hole 17, each protrusion 19a engages with the slit 16a on both sides, and as shown in FIG. , press the pressing piece part 20 in the combined state due to such temporary insertion, and insert the insertion part 19.
When completely inserted into the insertion hole 17, the insertion part 19
The distal ends of the leg portions 16 of the base body 14A come into contact with the thick inner wall surface, and the leg portions 16 are expanded laterally through the slits 16a.

Therefore, using the above-mentioned clip 14, connect the straight retaining wire 11 to the roof rail 2.
4A, a straight retaining wire 1 is inserted into the fitting hole 15 of the base body 14A to which the expansion body 14B is joined by the temporary insertion work described above, as shown in FIG. 4A.
1, the legs 16 of the base body 14A are fitted into the locking holes 13 of the extension piece 12 from below, and then, as shown in FIG. When the clip 20 is pressed upward, the insertion portion 19 is completely inserted into the insertion hole 17 in accordance with the pressing, and the leg portion 16 is expanded to the left and right within the locking hole 13, so that the clip 14 is locked due to this expansion. The retaining wire 1 is securely connected to the stopper hole 13 as shown in FIG.
Both ends 11a and 11a of 1 are attached to roof rails 2 and 2.
It can be easily installed. In addition, in such an attached state, the edge of the pressing piece 20 is locked by the engaging claw 18a of the locking piece 18, as shown in the figure, to prevent the insertion part 19 from falling. Although there is no need to worry about the leg section 16 being released from its expansion by descending, if it becomes necessary to remove it,
After unlocking the locking piece 18, the pressing piece 20
By pulling out the insertion part 19 downward, the insertion part 19 can be changed from the fully inserted state to the temporary insertion state immediately, so that the locking hole 13
It becomes possible to pull out the legs 16 of the clip base 14A from the clip base 14A.

In the above embodiment, the extension pieces 12 are provided at intervals at the upper end of the roof rail 2, but as shown in FIG. It is also optional to form locking holes 13 in the piece 12 at predetermined intervals depending on the implementation.

As described above, the present invention extends an extension piece that bends inward at the upper end of the roof rail, and a locking hole that opens downward is bored in the extension piece, and a straight resting piece is inserted into the locking hole. Since both ends of the wire are attached from below via clips, it is not possible to bend the entire resting wire into a bow shape as in the past, or to bend both ends further outward. Since there is no need to do this at all, the number of manufacturing steps can be effectively reduced, and the length of the resting wire itself can also be shortened.

In addition, the fact that the resting wire is straight can solve the problems of the conventional method, such as unnecessarily narrowing the ceiling space due to the bent bases at both ends of the resting wire. Since the height can be made as low as possible compared to the conventional one, the ceiling space can be expanded from this point of view as well, making it an optimal mounting structure.

In addition, all that is required is to engage the legs of the clip base from below into the locking holes that open downward, and to raise and fully insert the expandable body that has been temporarily inserted into the insertion holes of the legs. During the installation process, the legs can be expanded to allow both ends of the retaining wire to be securely and easily attached to the roof rail.
Since there is no downward rotation at all, this can greatly contribute to improving work efficiency.
