Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a mounting structure for, for example, an interior part of an automobile for mounting the interior part in a predetermined position.

[Prior art and its problems]

A conventional mounting structure for interior parts is disclosed in, for example, Japanese Utility Model Application No. 55-27146.

That is, as shown in FIG. 5, the groove wall 2 has a U-shaped cross section.
1, the side part of the groove wall 21 is installed on the clip 20, and a claw 22 extending inward and in an inclined shape is inserted into the groove wall 21 by forcibly pressing the protrusion 25 integrally molded on the interior part. When the clip 20 is fixed by engaging the outer surface of the protrusion 25, and then inserting the integrated clip 20 into the hole 27 of the panel plate 26, the clip 20 can be extended outwardly. The engaged portion 23 is connected to the peripheral edge 28 of the drilled hole 27.
Further, a flange 24 integrally extending outward at the open end of the groove wall 21 is configured to be secured to the panel surface.

However, in such a structure, the groove wall 21 of the clip 20 is inserted into the protrusion 25 of the interior component, and is locked only by the claw 22 of the groove wall 21, while the panel plate 26 is locked by the claw 22 of the spring 29. Since the clips 20 are independently locked only by the engaging portions 23, the ability of the clips 20 to fix the projections 25 is weak, and when the clips 20 are removed from the holes 27 of the panel board 26, the clips 20 do not fit into the holes 27. There are cases where the protrusion 25 is detached from the protrusion 25 in the same state.

Furthermore, depending on the method of inserting the clip 20 into the protrusion 25, there is a problem in the accuracy of the attachment, resulting in a slanted shape or a partially loose shape, which also poses problems from the viewpoint of reuse.

In order to solve the above-mentioned problems, Japanese Patent Application Laid-Open No. 164454/1983, shown in FIG. 6, was disclosed.

That is, the metal clip 30 has a groove wall 31 having a U-shaped cross section, and the groove wall 31 has an integral flange 32 extending outward from the open end and a protruding portion extending outward at the intermediate portion. 34 and a spring 33 having an engaging portion 35;
and a leg 4 having locking portions 42 arranged in parallel on both sides of the protrusion 40 and locking the flange 32.
1, and an insertion opening 44 for sliding and inserting the clip 30 from the side surface of the projection 40 and locking it at a predetermined position is formed together with a stopper 43 that is connected to the projection 40 in a direction perpendicular to the projection 40. It's summery.

To attach these, the groove wall 31 of the clip 30 is slid laterally from the side surface of the protrusion 40 and pressed and inserted to the stopper 43 position, and the flange 32 is locked to the inner surface of the locking portion 42.

Then insert the clip 3 into the drilled hole 37 of the panel board 36.
If it is pressed and inserted from the bottom of the spring 33, it will be fixed by the protrusion 34 of the spring 33.

However, when using such a configuration, the metal clip 30 must be inserted by sliding it laterally from the side surface of the protrusion 40, which reduces work ability and makes mass production difficult. .

Also, the flange 32 of the metal clip 30
Since the mold is inserted into locking portions 42 formed on parallel legs 41, the structure of the mold becomes complicated, resulting in a cost disadvantage.

Furthermore, the presence of the stopper 43 restricts the mounting direction, which may be inconvenient depending on the shape or mounting position of the interior parts.

[Means for solving problems]

The present invention was developed in order to effectively solve the problems of the prior art, and includes a groove wall having a U-shaped cross section, a protrusion whose diameter expands outward, and a protrusion. a clip body consisting of an engaging part that is continuous with the clip body and has a free end with a diameter reduced inward, and a flange that extends obliquely onto the bottom plane of the U-shaped groove wall; To provide a mounting structure that is much more effective than conventional techniques, since it is composed of a main body that is inserted into the groove wall and a fitting body that is connected to the side surface of the main body and includes a side wall surface that includes a snap body. was completed.

[Effect]

Therefore, in the present invention, the flange formed at an angle on the bottom plane of the groove wall having a U-shaped cross section is configured to engage with the main body of the fitting body formed on the interior component and the snap body. Because of this, it is now possible to install it reliably and firmly with only vertical sliding movement while absorbing dimensional errors.

〔Example〕

Hereinafter, the present invention will be described based on illustrated embodiments.

The mounting structure of the automobile interior parts according to the present invention is as shown in FIGS. 1 to 3.
and a fitting body 10.

The clip body 1 is formed of a spring material made of a thin metal plate, and has a groove wall 2 bent in a U-shaped cross section at the middle portion thereof, and the groove wall 2 has a protrusion that is inclined outward and has an enlarged diameter. It consists of an engaging part 4 which has a free end 5 and whose diameter is reduced inwardly continuously from the part 3 and the protruding part 3, and a flange 6 which extends obliquely onto the bottom plane of the U-shaped groove wall 2. There is.

The flange 6 extends in the same direction as the wall surface of the groove wall 2, but the engagement effect is even better if the tip is flared toward the end.

In addition, a predetermined number of fitting bodies 10 are integrally molded at predetermined intervals on the back surface of the interior component 16, and a plate-shaped main body 11 is provided in the center with some spacing on both sides of the main body 11, or the fitting bodies 10 are arranged in a continuous manner. A side wall surface 12 is formed with a snap body 14 bent inward at the uppermost end, and a step 12a widened to the same width is stepped at the lower end with the same square body at the front and rear.

In FIG. 2, a certain distance is shown between the main body 11 and the side wall surface 12.

A space 15 sufficient for fitting the flange 6 is formed between the upper end surface of the main body 11 and the lower surface of the snap body 14, and a space 15 is formed on both sides of the main body 11, which is slightly wider than the width of the groove wall 2. A rod-shaped guide body 13 is provided to protrude in parallel.

Next, the effect will be explained.

As mentioned above, a plurality of integrally molded fitting bodies 10 are arranged at predetermined intervals on the back surface of the interior component 16 shown in FIG. Make them face each other.

At this time, the clip body 1 holds the plate-like shape of the main body 11 between the groove walls 2, and slides between the parallel guide bodies 13 to be elastically engaged.

As a result, the groove wall 2 comes into close contact with the main body 11, and at the same time the elastic flange 6 passes over the snap body 14 against resistance and is elastically inserted into the gap 15.

Then, the inclined body is stabilized between the lower surface of the snap body 14 and the upper surface of the main body 11, and the tip end surface of the flange 6 is fixed in contact with the lower surface of the snap body 14.

As a result, the clip body 1 and the fitting body 10 are integrally fitted together.

If the interior component 16 is pressed into the hole in the panel plate after integral fitting as described above, the periphery of the panel hole will climb over the protrusion 3 and reach the locking portion 4, where it will be locked.

Therefore, by utilizing the inclined elastic force of the flange 6, it is possible to obtain an effect in which dimensional errors can also be absorbed due to the existence of the gap 15.

Further, the presence of the step 12a means that when the panel is inserted into the punched hole, the panel surface comes into contact with the step 12a surface, creating a gap equal to the height of the step 12a, which functions for positioning.

〔effect〕

As described above, the present invention forms a groove wall with a U-shaped cross section, and includes a protruding portion of the groove wall that expands in diameter outward, an engaging portion that continues to the protruding portion and decreases in diameter inward, and has a free end, and a U-shaped a clip body consisting of a flange extending obliquely onto the bottom plane of the groove wall; a main body erected on the back surface of the interior component and inserted into the groove wall; and a clip body connected to the side surface of the main body;
By providing a mounting structure for interior parts that includes a fitting body formed of a side wall surface having a snap body, the following effects can be achieved.

(1) The clip body only needs to be inserted for sliding movement in the vertical direction, and the presence of the guide body allows it to be easily attached to a predetermined position.

(2) Fixation is achieved by the flange being engaged with the snap body, but dimensional errors can be absorbed by the slanted flange.

(3) Since the groove walls are introduced by parallel guide bodies, stable holding is possible without the occurrence of vibrations or other looseness.
