Description

[Detailed Description of the Invention] "Industrial application field" The present invention relates to a drainage clip which is provided on the roof side of an automobile and can efficiently drain rainwater that has dropped onto the roof downward. Is.

"Prior Art" In automobiles, in order to efficiently drain the drainage flowing out of the cooler unit downward, for example,
A clip for drainage is provided as shown in Japanese Patent No. 11218.

Although not specifically shown, the drain drain clip is composed of a hollow base body fixed to the vehicle body panel side, and a hose portion integrally connected to the hollow base body,
The former hollow base body is configured so that it can be fixed to a mounting hole of a vehicle body panel through a flange portion and a locking shoulder portion formed on its outer peripheral wall surface. By connecting the connecting pipe of the cooler unit to, the drain flowing out from the cooler unit can be efficiently drained from the hollow base body to the lower part of the vehicle through the hose portion.

On the other hand, in a roof part of an automobile, a roof panel is constructed by a roof panel without using a single roof panel, and a roof separately formed with a lighting window or the like for the roof panel in the frame form. There is also a structure in which a structure is fixed by welding.

Moreover, in the roof portion using such a separately molded roof structure, it is desired that the rainwater that has fallen is efficiently drained downward more than the ordinary automobile roof portion because of its structure. It is possible to efficiently drain rainwater using the drainage clip of.

"Problems to be solved by the invention" However, in the roof part using the roof structure, the roof panel for constructing the frame and the frame panel of the roof structure are finally fixed by welding. However, in this fixed state, a fixed gap is defined between both panels, and considerable variation occurs in the gap, so the drainage clip used on the roof side. Is required to be reliably provided in such a gap and efficiently absorb the variation.

However, as described above, the drain drainage clip is fixed to the mounting hole of the vehicle body panel simply by the flange portion and the engaging shoulder portion provided on the side surface of the hollow base body. It has no function of absorbing variations.

Therefore, it is not possible to use the drain drainage clip as it is as a rainwater drainage clip on the roof of an automobile, because it is completely impossible in terms of function. Is desired.

Thus, the present invention provides a new drainage clip that can meet such demands.

[Means for Solving the Problems] To achieve the above object, the present invention provides a drainage clip interposed between a roof panel and a frame panel that is welded to the roof panel to define a gap. On the premise of the above, a hollow base body having an upper end opening corresponding to the rainwater introduction port of the frame panel and fixed to a mounting hole of a roof panel, and a connecting pipe portion continuously connected to the hollow base body. The hollow base body is provided with a plurality of elastic locking pieces projecting outwardly on the outer peripheral wall so as to be bendable outward, and the roof is provided at a portion of each of the elastic locking pieces that is locked to the edge of the mounting hole. Depending on the size of the gap defined between the panel and the frame panel, a taper portion that can be locked to the hole edge of the mounting hole of the roof panel is formed, and the taper portion of each elastic locking piece is locked by the locking action. , The above hollow substrate to the roof panel mounting hole Adopted a structure that sticks to.

Therefore, when the drainage clip of the present invention is provided between the roof panel and the frame panel of the automobile roof, first, the hollow substrate is inserted from below the mounting hole of the roof panel. After temporarily fixing the hollow base to the mounting hole, align the rainwater inlet of the frame panel with the upper end opening of the hollow base, and weld the frame panel onto the roof panel. Clips are provided between the roof panel and the frame panel.

Therefore, after that, if a hose arranged inside the body of the car is connected to the connecting pipe part of the clip, the rainwater that falls on the roof part of the car will be discharged from the rainwater inlet of the frame panel to the inside of the clip and the hose. After that, it becomes possible to efficiently drain the water below the vehicle.

However, when the frame panel is welded to the roof panel, if there is a variation in the gap defined between the two, the taper portion formed on each elastic locking piece has the above-mentioned gap size. Accordingly, the hollow base body can be securely fixed to the mounting hole by elastically locking to the hole edge of the mounting hole of the roof panel, so that, for example, there is variation in the defined gap. However, this variation can be effectively absorbed and the ideal condition of the drainage clip can be always ensured.

[Examples] Hereinafter, the present invention will be described in detail with reference to each illustrated example.

In each of the embodiments, as shown in FIG. 1, an automobile in which a separately molded roof structure R including a lighting window and the like is fixed to a roof panel P1 that constructs a framework of an automobile roof by welding is targeted. , A drainage clip 1 interposed between the roof panel P1 and the frame panel P2 of the roof structure R
Is shown.

The drainage clip 1 according to the first embodiment is an integrally molded product of synthetic resin, and has a mounting hole for the roof panel P1 as shown in FIG.
A bottomed hollow substrate 2 fixed to H1 with an open upper end,
It is composed of a connecting pipe portion 3 continuously provided on the side portion of the hollow substrate 2.

Then, the former hollow substrate 2 has three recesses 4 intermittently formed on the outer peripheral wall surface thereof at predetermined intervals, and elastically locked to the upper edge of each recess 4 with a certain space therebetween. The pieces 5 are vertically bent so that they can be bent inward and outward, and the outer peripheral wall surfaces where the recesses 4 are not formed are respectively provided with flange portions 6 projecting outward, while the outer periphery of each elastic locking piece 5 is provided. A stopper portion 7 that locks to the upper edge of the mounting hole H1 of the roof panel P1 is provided in a substantially central portion of the surface, and the roof panel P1 and the frame panel of the roof structure R are provided on the lower outer peripheral surface of the stopper portion 7. A tapered surface 8 serving as a locking means that can be locked to the hole edge of the mounting hole H1 of the roof panel P1 is formed in accordance with the gap defined between P2.

The latter connecting pipe portion 3 is for connecting a hose arranged inside the body of the automobile, and has an annular step portion 9a and a projection 9b for surely connecting the hose at its tip portion. It is composed.

Therefore, the drainage clip 1 having such a configuration is used for the roof panel.
In the case of interposing between P1 and the frame panel P2 of the roof structure R, first, as shown in FIG. 3, the elastic locking pieces 5 in the vertical state are flexed inward to obtain the roof panel. P1
From the bottom of each mounting hole H1 formed in the hollow base 2
Are inserted until the respective flange portions 6 come into contact with the lower surface of the roof panel P1, and the hollow base 2 of the clip 1 is attached to the respective mounting holes H1.
Again, temporarily stop.

Then, this time, the inlet H2 formed in the frame panel P2 of the roof structure R is aligned with the opening of each hollow substrate 2, and at the same time, the bending guide G formed in the hole edge of the inlet H2. To obtain a state in which is inserted into the opening of each hollow substrate 2,
If the frame panel P2 is welded to the roof panel P1, each drainage clip 1 is provided between the roof panel P1 and the frame panel P2 of the roof structure R. If a hose (not shown) is connected, it will be possible to efficiently drain the rainwater that has dropped onto the roof from the inlet H2 of the frame panel P2 through the inside of the clip 1 and the hose to the lower part of the vehicle. .

However, when the frame panel P2 is welded to the roof panel P1 and the gap L defined between both panels P1 and P2 is large, as shown in FIG. 4A, each flange portion 6 is attached to the bottom surface of the roof panel P1. The lower end side of the tapered surface 8 of each elastic locking piece 5 is elastically locked to the hole edge of the mounting hole H1 to securely fix the hollow base 2 to the mounting hole H1 in a state of contacting with the mounting hole H1. Therefore, even if the gap is large, therefore, the introduction port H2 of the frame panel P2 and the opening of the base body 2 are reliably joined via the bending guide G described above,
No more worrying about leaking rainwater.

Further, when the gap L between the panels P1 and P2 is small, as shown in FIG. 9B, this time, each elastic locking piece 5 is flexed toward the inner side, and the stopper of each elastic locking piece 5 is obtained. Part 7 is a mounting hole
The hollow substrate 2 descends in the mounting hole H1 until it abuts the hole edge of H1, and at this position, the tapered surface 8 of each elastic locking piece 5 is moved.
Since the upper end side of the frame panel P1 is locked to the hole edge of the mounting hole H1 of the roof panel P1, even if the gap is small, the folding port G2 and the opening of the base body 2 can be bent by the bending guide G. It is surely joined via.

In addition, although each of the above figures illustrates the case where the gap L is the maximum and the case where the gap L is the minimum, the case where the gap between both panels P1 and P2 is an intermediate size is also concrete. Although not shown in the drawing, under the same principle, the tapered surface 8 of each elastic locking piece 5 is elastically locked to the edge of the mounting hole H1 according to the size of the gap L, It goes without saying that the inlet H2 of the frame panel P2 and the opening of the base 2 can be reliably joined together via the bending guide G.

Therefore, in the clip 1 of the first embodiment, even if there is any variation in the gap L defined between both panels P1 and P2, the variation is caused by the tapered surface 8 of each elastic locking piece 5. Since it is possible to efficiently absorb the clip, the ideal interposition state of the clip 1 is always guaranteed.

Next, the drainage clip 1 according to the second embodiment will be described. The clip 1 of this embodiment is basically the same as that of the above-mentioned first embodiment, but the difference is shown in FIG. As shown, the elastic locking piece 5 is laterally provided at one end edge of each recess 4 of the hollow base 2 so as to be bendable inward and outward, and at the lower end edge of each elastic locking piece 5 excluding the tip end. In accordance with the gap L defined between the roof panel P1 and the frame panel P2 of the roof structure R, a tapered wall 10 as a locking means that can be locked to the edge of the mounting hole H1 of the roof panel P1 is integrally extended. The lower surface of the distal end portion of the elastic locking piece 5 which is provided and is not provided with the tapered wall 10 is a stopper portion 11 similar to that of the first embodiment.

Therefore, even when the drainage clip 1 of the second embodiment is provided between the roof panel P1 and the frame panel P2 of the roof structure R, the inside of each elastic locking piece 5 in the horizontally installed state. The bending of the hollow base body 2 is applied to the roof panel P1 from below the respective mounting holes H1 of the roof panel P1.
The hollow base 2 of the clip 1 is temporarily fixed to each mounting hole H1 and then, similarly to the first embodiment, the inlet H2 of the frame panel P2 and each hollow base. If the two openings are aligned and the frame panel P2 is welded to the roof panel P1, each drainage clip 1 is securely provided between the roof panel P1 and the frame panel P2 of the roof structure R. Becomes

Even in the second embodiment, when the frame panel P2 is welded to the roof panel P1 and the gap L defined between the panels P1 and P2 is large, as shown in FIG. While the flange portion 6 remains in contact with the lower surface of the roof panel P1, each elastic locking piece 5 expands outward by its own elasticity, and the lower end side of each taper wall 10 is attached to the mounting hole H1. Since the hollow base 2 is securely fixed to the mounting hole H1 by elastically engaging with the hole edge, even if the gap L is large, this allows the introduction port H2 of the frame panel P2 and the base 2 to be fixed. Is securely joined to the opening of the through the bending guide G,
No more worrying about leaking rainwater.

Further, when the gap L between the panels P1 and P2 is small, as shown in FIG. 7B, this time, the elastic locking pieces 5 are flexed toward the inside, and the elastic locking pieces 5 are bent. The hollow substrate 2 descends in the mounting hole H1 until the stopper portion 11 contacts the hole edge of the mounting hole H1, and at this position, the upper end side of the tapered wall 10 is locked to the hole edge of the mounting hole H1. Therefore, this allows the hollow substrate 2
Is firmly fixed to the mounting hole H1 and the gap L is small, the introduction port H2 of the frame panel P2 and the opening of the base 2 are reliably joined via the bending guide G.

Even in this case, the gap L between both panels P1 and P2
, But when the size is between the maximum and minimum,
Under the same principle, according to the size of the gap L, the taper wall 10 of each elastic locking piece 5 elastically locks to the hole edge of the mounting hole H1, and the introduction port H2 of the frame panel P2. It goes without saying that the opening and the opening of the base body 2 are surely joined to each other via the bending guide G.

Therefore, even in the clip 1 of the second embodiment, even if there is any variation in the gap L defined between the panels P1 and P2, it is possible to efficiently absorb the variation. Therefore, the ideal interposition state of the clip 1 is always guaranteed.

In addition, in each of the above-described embodiments, the clip 1 is provided at the four corners of the roof portion of the automobile. However, the location and the number of the clip 1 can be appropriately changed according to the implementation. Of course.

“Effect of device” As described above, the present invention is
In the roof part of a car, even if there is variation in the gap defined between the roof panel and the frame panel,
Since it is possible to effectively absorb the variation, it is possible to always guarantee the ideal interposed state of the drainage clip.

Therefore, the present invention can provide the most suitable drainage clip for the first time, especially for draining rainwater that has fallen on the roof of an automobile.
