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. 6, the groove wall 2 has a U-shaped cross section.
1, a claw 22 installed on the side of the groove wall 21 and extending inwardly and in an inclined manner forcibly presses a protrusion 25 integrally molded on the interior part to press the protrusion 25 into the groove wall 21. When inserted, the protrusion 25
If the integrated clip 20 is inserted into the perforation hole 27 of the panel plate 26, the outwardly extending engaging portion 23 of the clip 20 will be inserted into the perforation hole 27 of the panel plate 26. The flange 24 is engaged with the peripheral edge 28 of the hole 27, and the flange 24 integrally extended outward at the open end of the groove wall 21 is engaged with 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.

Further, depending on the method of inserting the clip 20 into the protrusion 25, there were problems with the accuracy of the attachment, resulting in a slanted shape or a partially loose shape, which also caused problems from the viewpoint of reuse.

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

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 conventional technology, and is provided in the middle part of the groove wall with a U-shaped cross section and the groove wall, and is attached to the periphery of the hole in the vehicle body panel. a spring having an engaging portion and a protrusion protruding outward from the U-shaped groove wall and coupled to the bottom; and a spring provided at an open end of the groove wall and extending outward from the U-shaped groove wall;
and a mounting member comprising a flange having a pointed claw, a main body part having a predetermined width that is provided on the back surface of the interior component and inserted into the groove wall, and a mounting member on both sides of the main body part that presses the flanges in the direction of the main body part. By forming the pair of legs at the positions shown in FIG.

[Effect]

Therefore, in the present invention, a sharp claw is formed at the end of the flange at the open end of the groove wall having a U-shaped cross section, and the sharp claw is forcibly pressed toward the main body by the legs. By obtaining the deformation pressure of the flange, it was possible to firmly fix the flange, and it was also possible to insert the flange vertically in a straight line from above.

〔Example〕

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

The structure of the mounting structure for automobile interior parts according to the present invention is illustrated in FIGS. 1 to 3.

That is, FIGS. 1 and 2 show a metal mounting member 1, which has a U-shaped cross section and a groove wall 2 bent from the center as shown in the figure, with the bent part being a circular bottom part 9 and the open end being a groove wall 2 bent from the center. The outwardly extending flange 3 has a pointed claw 7 at its tip.
A plurality of these are formed to form a tilted body.

A spring 4 protrudes outward from the center of the groove wall 2 by joining with a bottom part 9, forming a protruding part 5 at approximately the middle part, and a connecting part 6 bent in a dogleg shape, thereby absorbing the load. The structure is such that it can be bent inward by being received.

Further, a locking pawl 8 is formed which extends inwardly from the intersection line of the flange 3 and the groove wall 2 connected to the flange 3 and toward the bottom 9 as a slope.

Such a configuration can be mass-produced by continuously pressurizing the thin metal spring material using a press mold.

FIG. 3 shows a plurality of projections 10 for insertion into the groove wall 2 of the mounting member 1, which are integrally molded at predetermined intervals on the back surface of the elongated interior component 14 shown in FIG. It is something.

As shown in the figure, the protrusion 10 includes a main body 11 having a width approximately equal to the width of the groove wall 2, and side plate members 12 which are widened in parallel at both ends of the main body 11 and serve as guides when the mounting member 1 is inserted. and walls 13 which are located on both the front and rear sides of the main body part 11 and are spaced apart from each other by a predetermined distance and have a shape that is somewhat higher than the inclination height of the flange 3.

Next, the effect will be explained.

As described above, a plurality of protrusions 10 are already integrally formed at equal intervals on the back surface of the interior component 14 shown in FIG. The open ends of the two are facing each other.

If the opposing mounting members 1 are pressed in the same state, they will have a guiding effect along the side plate 12 and the groove wall 2
is inserted into the

That is, when the locking pawl 8 is slid from above along the outer wall surface of the main body 11 as shown in FIG. It will bite in the direction that resists.

If the sliding further continues to the bottom of the main body 11, the flange 3 will be inserted between the main body 11 and the pair of legs 13, but the width of the pair of legs 13 will be wider than the width of the flange in the free state.
The width between them is narrower, so that the flange 3 is forcibly bent as shown in Figure B, and the pointed pawl 7 is engaged with the inner wall surface of the leg 3 and by the bending force of the flange 3. The retaining claw 8 further increases the pressing force against the outer wall surface of the main body portion 11.

Therefore, the mounting member 2 can be firmly held by the synergistic effect of the distance between the main body portion 11 and the pair of legs 13 and the bite between the flange 3 and the pointed claws 7.

Furthermore, when the panel 15 is inserted into a predetermined circular hole in the mounting member 1, the panel 15 comes into contact with the upper end surface of the legs 13 and stops. A gap occurs and panel 15
This makes it possible to regulate a predetermined position.

The gap can also be used as a holding passage for electric wires that are routed through the vehicle body.

〔effect〕

As described above, the present invention includes a groove wall having a U-shaped cross section, an engaging portion provided at an intermediate portion between the groove walls, and engaging the periphery of the hole in the vehicle body panel, and an engaging portion protruding outward from the U-shaped groove wall and coupled to the bottom portion. a spring having a protruding portion, a flange provided at the open end of the groove wall, extending outward from the U-shaped groove wall, and having a pointed claw; To provide a mounting structure for an interior component, which is composed of a main body part having a predetermined width that is inserted into a groove wall, and a pair of legs located on both sides of the main body part and at positions that press the flanges in the direction of the main body part. This brings about the following effects.

(1) Since the main body and the integrated legs are erected in parallel, the mounting member can be slid in the vertical direction, and the mounting can be automated and mass productivity can be achieved.

(2) The mounting member can be opened from the main body without damaging the sharp claws, and can be reused.

Moreover, sliding in the vertical direction is sufficient for opening.

(3) Due to the presence of the legs, the flange can be bent and the mounting member can be held under strong pressure to the main body.

(4) The presence of the legs makes it possible to control the position of the panel and keep it in a constant position at all times.
