[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improved structure for fixing two articles.

[0002]

2. Description of the Related Art A conventional structure for fixing two articles will be described below by taking a drafter assembly of an automobile as an example.

As shown in FIGS. 8 and 9, a conventional drafter assembly 10 has a drafter body 1 made of a flexible resin.
And the duct 11, the opening 3 of the drafter body 1
Are engaged with the plurality of engaging holes 14 provided on the periphery of the opening 13 of the duct 11, and the mounting holes provided on the flanges 2 and 12 of the two. 8 and 18 are joined to each other to form a closed space 20 between the drafter main body 1 and the duct 11.

[0004]

However, in the above-described conventional configuration, the engaging claw 4 of the drafter main body 1 has the duct 1
In the engaging portion 9 engaged with the first engaging hole 14, the portion where the drafter main body 1 and the duct 11 are in contact with each other is small, or the gap t exists between the two, so that the vibration As a result, there is a problem that rattling noise and displacement occur between the drafter main body 1 and the duct 11.

An object of the present invention is to solve the above-mentioned problem, and an object of the present invention is to provide a structure for securely fixing two articles without generating rattling noise or displacement between the two articles.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to a method in which an engaging claw provided on the periphery of an opening of one flexible resin article is connected to the other flexible resin article. A closed structure that forms a closed space by engaging with an engaging hole provided in a peripheral edge of the opening of the two articles, wherein the engaging claw is located near one of the engaging portions of the two articles. An elastic projection is provided for urging the other in the detaching direction when engaged with the engagement hole.

[0007]

According to this structure, when the engaging claw of one article is engaged with the engaging hole of the other article, the elastic projection provided near the engaging portion of one of the articles can fix the other article. Since the two articles are urged in the detaching direction, there is no gap between the two articles, and no rattling noise or displacement occurs, and the articles are securely fixed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS (Embodiment 1) An embodiment of the present invention will be described below with reference to FIGS. The same components as those shown in the conventional example are denoted by the same reference numerals.

FIG. 1 is an exploded perspective view of a drafter assembly 10 having a structure for fixing two articles of the present invention, FIG. 2 is a perspective view of a drafter body 1 as one article, and FIG. 3 is a duct as the other article. It is a perspective view of 11.

Referring to FIG. 1, a drafter assembly 10 includes a drafter main body 1 and a duct 11 joined to the drafter main body 1 to form a closed space 20.

A drafter body 1 made of a flexible resin such as PP (polypropylene) or ABS (acrylonitrile butadiene styrene), which is relatively thin, has a flange 2 on the outer periphery, and a rib 6 on the inner periphery of the flange 2. , And the inner surface of the rib 6 is formed in the opening 3.
A plurality of engaging claws 4 having slits 5 on both sides are formed at appropriate positions of the rib 6 so as to protrude toward the duct 11. Further, mounting holes 8 are provided in the flanges 2 on both sides of the drafter main body 1.

The duct 11 made of a flexible resin is provided with a flange 12 on the outer periphery, and a rib 19 is provided on the inner periphery of the flange 12 so as to project from the inner surface of the rib 19. A plurality of engaging holes 14 are formed at appropriate positions of the rib 19 in correspondence with the engaging claws 4 of the drafter main body 1. These engaging claws 4 and the engaging holes 14 form an engaging portion. 9. An elastic projection 15 is provided on an edge of the flange 12 near the engagement hole 14 so as to protrude. Duct 11
The mounting holes 18 are provided in the flanges 12 on both sides of the main body 1 and face the mounting holes 8 of the drafter main body 1.

As shown in FIG. 4, the elastic projection 15 has a projecting portion 16 which projects in a slanting direction toward the back of the duct 11,
A folded portion 17 connected to the protruding portion 16 is provided. When the engaging claw 4 of the drafter main body 1 is engaged with the engaging hole 14 of the duct 11, the tip 16a of the protruding portion 16 is connected to the flange 2 of the drafter main body 1. , So as to urge the drafter main body 1 toward the rear side of the duct 11.

As shown in FIGS. 5 and 6, the drafter assembly 10 constructed as described above has the rib 6 at the opening 3 of the drafter main body 1 and the rib 1 at the opening 13 of the duct 11.
When the engaging claws 4 of the drafter main body 1 are engaged with the engaging holes 14 of the duct 11,
The tip 1 of the protrusion 16 of the elastic projection 15 formed on
6a abuts on the flange 2 of the drafter main body 1 and urges the drafter main body 1 in the detaching direction, so that a gap is not formed between the engaging claw 4 and the engaging hole 14 and rattling or displacement occurs. There is no.

Embodiment 2 Hereinafter, a second embodiment of the present invention will be described with reference to FIG.

In the figure, 1 is a drafter body, 11 is a duct, and 15 is an elastic projection, which are the same as those in FIG. In this embodiment, the protrusions 16 of the elastic projections 15 of the duct 11 are provided on the flange 2 of the drafter main body 1.
6 is different from the configuration in FIG.

With the provision of the engagement hole 7, when the engagement claw 4 of the drafter main body 1 is engaged with the engagement hole 14 of the duct 11, the tip 16 of the protrusion 16 of the elastic projection 15 is provided.
a is fitted in the engagement hole 7 to urge the drafter main body 1 in the disengagement direction to eliminate the gap between the engagement claw 4 and the engagement hole 14 and to move the drafter main body 1 and the duct 11 up and down. To prevent backlash and misalignment in the left-right direction.

[0018]

As described above, according to the present invention, the engaging claw provided on the periphery of the opening of one flexible resin article is provided on the periphery of the opening of the other flexible resin article. A fixing structure of two articles that forms a closed space by engaging with an engaging hole, wherein the engaging claw is engaged with the engaging hole near one of the engaging portions of the two articles. Sometimes, by providing an elastic projection for urging the other in the detaching direction, it is possible to realize an excellent two-article fixing structure in which no gap is formed between the two articles and no rattling sound or displacement occurs.
