[0002]

2. Description of the Related Art To attach a defroster grill to an instrument panel main body, an elastic clip is previously attached to an air outlet of the defroster grill, and the air outlet together with the elastic clip is attached to a mounting opening of the instrument panel main body. It is configured to be inserted with one touch by inserting and automatically engaging the engaging portion of the elastic clip to the edge of the mounting opening using elasticity. Has been made.

In order to securely attach an elastic clip to a defroster grill, for example, Japanese Utility Model Laid-Open No. 59-12295.
The proposal disclosed in Japanese Patent Publication No. 1 is one of them. In this proposal, as shown in FIG. 4, a clip mounting portion 2 is integrally protruded from a rear wall outer surface of an air outlet portion 1a of a defroster grill 1, and an elastic clip 3 is firmly mounted on the clip mounting portion 2. It is.

The clip mounting portion 2 has a tunnel-shaped clip engaging base 2b whose upper surface is tapered following the side surface of the step portion 2a. This engagement base 2b
As shown in FIG. 5, the insertion portion 3b of the elastic clip 3 obtained by pressing one metal plate is engaged. The insertion portion 3b is formed by bending one end of a rectangular plate material main body 3a into a substantially U-shape, and the other end of the plate material has a substantially rectangular shape opposite to the bent side of the insertion portion 3b. The frame-shaped engaging piece 3c protruding outward is raised at a predetermined angle. In the frame of the engaging piece 3c, claw pieces extending in parallel to the base end of the protruding piece 3d are provided at the left and right ends of the tip of the protruding piece 3d cut out from the edge of the plate material main body 3a. 3e.

When the insertion portion 3b of the elastic clip 3 having the above configuration is inserted into the engagement base 2b from below, the claw piece 3e is connected to the clip mounting portion 2 as shown in FIG.
The defroster grille 1 and the elastic clip 3 are integrated with each other. In this state, inserts the air outlet portion 1a of the defroster grill 1 on the mounting opening of the instrument panel main body, engaging piece 3 c of the elastic clip 3 is once elastically deformed by being pushed by the opening edge of the opening Suruga, engaging piece 3 c is restored to the original shape when passing through the same opening edge, tip of the fastening piece 3 c as shown in FIG. 7 is engaged with the opening edge 4a, defroster grill 1 is instrumented It is mounted and fixed to the panel body 4.

[0006]

According to the mounting structure of the defroster grill 1 disclosed in the above-mentioned publication, the elastic clip 3 is inserted into the front and back surfaces of the clip mounting portion 2 projecting from the rear wall outer surface of the defroster grill 1. The elastic member 3 is elastically wrapped by the portion 3b, and the claw 3e of the elastic clip 3 is engaged with the step 2a of the clip mounting portion 2, whereby the removal of the defroster grill 1 and the elastic clip 3 is strongly restricted. It is.

However, according to the above structure, the elastic clip 3 is formed by bending a single metal plate in the length direction as described above, and its elastic force is along the length of the plate. Although it acts, there is no elastic force along the left and right width directions, and therefore, elastic deformation in the length direction is likely to occur. Moreover, no engaging means is provided on the left and right sides of the elastic clip 3 and the clip mounting portion 2 for engaging each other.

Accordingly, in the mounting structure of the defroster grill 1, an unexpected external force is applied after the elastic clip 3 is mounted on the clip mounting portion 2 of the defroster grill 1 as shown in FIG. When the force is applied, the insertion portion 3b of the elastic clip 3 is easily opened, and the claw piece 3 locked to the step 2a of the clip mounting portion 2
e comes off from the stepped portion 2a, and the elastic clip 3 comes off the defroster grill 1 disadvantageously. This is also likely to occur after the defroster grill 1 is attached and fixed to the instrument panel main body 4 together with the elastic clip 3. When a force is applied in the direction of the arrow 7, the engaging piece 3b of the elastic clip 3 is elastically deformed, and the claw piece 3e locked to the step 2a of the clip mounting portion 2 comes off from the step 2a. The inconvenience that the elastic clip 3 falls off inside the panel main body 4 and tends to occur is likely to occur.

The present invention has been developed in order to solve such inconvenience, and an object of the present invention is to provide a rigidly mounted defroster grill and an elastic clip which do not easily fall off the elastic clip once mounted on the defroster grill. Developing a mounting structure for

[0010]

In order to achieve the above object, according to the present invention, an air outlet of a defroster grill is inserted into a mounting opening of an instrument panel main body, and an elastic clip attached to the grill is inserted. A mounting structure for a defroster grill, which is attached to the mounting opening by attaching a defroster grill, wherein the elastic clip is made of a single metal plate, has locking projections on at least the left and right sides of the main body, and The upper part has an engaging projection that engages with the edge of the mounting opening, and the outer surface of the rear wall of the air lead-out section is engaged with the locking projection on the left and right sides, respectively. The main configuration is that a clip mounting portion having a portion is protruded.

Of course, the clip mounting portion and the elastic clip are provided with appropriate locking means for locking not only the locked portion and the locking projection but also the upper and lower side surfaces of the clip mounting portion.

[0012]

In order to mount the elastic clip on the clip mounting portion of the defroster grill, the elastic clip is pressed against the surface of the clip mounting portion, and the left and right locking projections are elastically fixed on the left and right locked portions of the clip mounting portion. When it is deformed and spreads slightly to the left and right, and the elastic clip is pressed against the clip mounting portion, the locking end of the elastically deformed left and right locking protrusion returns to its original shape and locks to the left and right locked portion. I do.

[0013] Thus, once the elastic clip is mounted on the clip mounting portion of the defroster grill, the left and right locking projections of the elastic clip lock the clip mounting portion from right and left, and the elastic clip rises from the clip mounting portion. Not only does it disappear, but even if a strong force is applied in the direction that causes elastic deformation of the engaging projections of the elastic clip, the left and right locking projections are not easily elastically deformed, so the left and right locking of the clip mounting part There is no departure from the department.

When attaching the defroster grill with the elastic clip attached to the instrument panel body,
When the air outlet of the defroster grill is inserted into the mounting opening of the instrument panel body, the engaging projection of the elastic clip is pressed by the opening edge of the mounting opening on the way, and is elastically deformed once. When the intermediate bent portion of the engaging projection passes the opening edge, elastic return starts, and the distal engaging portion of the engaging projection engages with the opening edge, and the Finish the installation.

Therefore, according to the present invention, when the defroster grill with the elastic clip attached thereto is attached to the instrument panel main body, the air outlet of the defroster grill is simply inserted into the mounting opening of the instrument panel main body. It can be attached by simple operation. Then, after the attachment is completed, the force acts to pull out the defroster grill from the attachment opening, and even if a force for dropping the elastic clip from the clip attachment portion acts on the engaging projection, the clip attachment portion is not affected. Since the elastic clip is strongly connected to the left and right and up and down, the elastic clip does not elastically deform and does not fall off easily.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be specifically described with reference to the illustrated embodiments. FIGS. 1 to 3 show a mounting structure of a defroster grill which is a typical embodiment of the present invention. FIG. 2 is a sectional view of a main part showing a state where the defroster grill is mounted on an instrument panel body. FIG. FIG. 3 is an AA arrow view of FIG.

In these figures, reference numeral 11 denotes an air outlet portion of the defroster grill 10, and the overall configuration of the air outlet portion 11 is substantially the same as that of the related art in the form of a generally rectangular tube which is opened up and down. A flange 11a having a shape that fits into the inner surface of the mounting opening 14a of the instrument panel body 14 protrudes from the end. Also, on the lower outer surface of the rear wall (right wall in FIG. 1) 11b of the air outlet section 11,
Clip mounting part 1 which forms a part of the main components of the present invention
2 are protruding. Further, the rear wall (the right wall in FIG. 1) 11
b, the flange 1 is located above the clip mounting portion 12.
A seating portion 15 is formed in which a part of 1a is seated on an opening edge 14b of the instrument panel main body 14.

The clip mounting portion 12 has a rectangular frame shape that is long in the left and right directions (perpendicular to the plane of FIG. 1) and has a stepped locked portion 12a that protrudes left and right along the left and right edges. Also, a leg 1 of an elastic clip 13 described later is provided on the lower side (the lower side in FIG. 1) of the clip mounting portion 12.
A pair of left and right guide protrusions 12b for guiding 3d protrude.

On the other hand, the elastic clip 13, which is another main component of the present invention, is made of a substantially cross-shaped metal plate, and as shown in FIG.
Is bent obliquely inward while leaving a length equal to the left and right length of the clip mounting portion 12 in the central portion 13b, and the bent front end portion is further bent inwardly into a U-shape to form the locking projection 1
3b. Further, the long side of the cross shape is obliquely bent outward from the base end, and the distal end thereof is bent inwardly in the shape of a letter, and the distal end thereof is further bent outwardly in the shape of a letter to form the engaging projection 13c. Is configured. On the other hand, the short side of the cross shape is bent inward at a substantially right angle to form a leg 13d. And it cuts out in concave shape from the said central part 13b to the said engagement protrusion 13c, and the front-end | tip of the tongue part 13e is curved inward slightly.

The defroster grill 10 having the above configuration
In order to attach the elastic clip 13 to the clip attaching portion 12, the elastic clip 13 is pressed toward the clip attaching portion 12 as shown by an arrow in FIG. The inner surface of the bent portion of the clip abuts against the edges of the left and right locked portions 12a of the clip mounting portion 12, and the U-shaped bent portion of the left and right locking projection 13b is elastically deformed and slightly left and right. At the same time, the leg 13d of the elastic clip 13 fits between the left and right guide protrusions 12b of the clip mounting portion 12, and the tip of the tongue 13e elastically contacts the upper outer surface of the clip mounting portion 12, and the leg 13d and the tongue The upper and lower side surfaces of the clip mounting portion 12 are elastically held by the portion 13e.

Further, when the elastic clip 13 is pressed against the clip mounting portion 12, the locking ends of the left and right locking projections 13b, which have been elastically deformed, return to their original shapes, and at the same time, the inner surfaces of the step portions of the left and right locked portions 12a. To lock. At this time, the back of the central portion 13b of the elastic clip 13 is
2 is in close contact with the opening surface.

Once the elastic clip 13 is once mounted on the clip mounting portion 12 of the defroster grill 10 as described above, the distal ends of the left and right locking projections 13b of the elastic clip 13 are connected to the left and right locked portions 12a of the clip mounting portion 12. Since the elastic clip 13 is locked to the inner surface of the stepped portion from the left and right, the elastic clip 13 not only does not float up from the clip mounting portion 12, but also, for example, the engaging projection 13c of the elastic clip 13 is shown in FIG.
, Even if a strong force is applied in the direction of arrow C, the left and right locking projections 13b
There is no departure from.

In this embodiment, the elastic clip 1
3 is designed to be located between the seating portion 15 and the clip mounting portion 12, so that after the elastic clip 13 is mounted on the defroster grill 10, the seating portion 15 becomes a barrier. This further eliminates the possibility that an unexpected external force may be applied to the engaging projection 13c.

When the defroster grill 10 with the elastic clip 13 attached thereto is attached to the instrument panel main body 14, the air outlet 1 of the defroster grill 10 is simply used.
1 is the mounting opening 1 of the instrument panel body 14
It can be attached by a simple operation simply by inserting it into 4a.

That is, when the air outlet 11 of the defroster grill 10 is inserted into the mounting opening 14a of the instrument panel body 14, the elastic clip 1
3 is pressed by the opening edge 14b of the mounting opening 14a and is once elastically deformed to the position shown by the imaginary line in FIG. When the bent part 13c-1 passes through the opening edge 14b, the elastic return starts, and the outside of the bent part 13c-2 at the tip of the engaging projection 13c is the opening edge 14c.
b, the seat portion 15 of the defroster grill 10 is seated on the opening edge 14b of the instrument panel main body 14, and the attachment to the instrument panel main body 14 is completed.

After the attachment to the scale, the force for pulling out the defroster grill 10 from the attachment opening 14a acts, and the clip attachment portion 1 is particularly attached to the engaging projection 13c.
Even if a force is applied to drop the elastic clip 13 from the clip 2, since the clip mounting portion 12 and the elastic clip 13 are strongly connected left and right and up and down as described above, elastic deformation does not occur at the connection portion. It does not fall off easily.

[0027]

As is apparent from the above description, according to the present invention, at least the right and left directions in which the clip mounting portion of the defroster grill and the elastic clip elastically engage with the instrument panel body of the elastic clip are at least right and left. , The elastic clip does not easily come off after the elastic clip is once mounted on the clip mounting portion, and even less does not drop into the inside of the instrument panel body.
