[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIGS. 1 to 6 show a clip 1 according to the present invention.
7 to 14 show a component mounting structure and a component mounting method using the clip 1 according to the present invention. In this component mounting structure and the component mounting method, as best shown in FIG. 11, the mounting component 2 has a bolt 3 erected. 4 is mounted in the mounting hole 5. Although the bolt 3 is a bolt called a weld bolt in the illustrated example, it may be a stud bolt, and any bolt can be used as long as it is set up on the mounting component 2.

First, the details of the clip 1 will be described with reference to FIGS. The clip 1 is integrally formed of plastic, and includes a circular flange 7 and a shaft 8 having a rectangular cross section inserted into a mounting hole of the panel. A bolt receiving hole 9 is formed in the flange 7 and the shaft portion 8 to receive a bolt erected on the mounting part. The portion of the flange 9 of the hole 9 is tapered so that the bolt can be easily received. The opposite end of the shaft portion 8 is tapered at two ends so that the front end (lower end) of the shaft portion 8 can be easily inserted into the mounting hole of the panel. A pair of elastic panel locking claws 10, 10 are formed on the outer surface of the shaft portion 8 so as to extend from the front end of the shaft portion toward the flange 7 and project outward in the radial direction. The tip portions of the panel locking claws 10 and 10 elastically project outward in the radial direction, and when the shaft portion 8 is inserted into the mounting hole of the panel, it once bends inward and then projects again, and the flange 7 It engages with the back side of the panel in contact, whereby the clip 1 is attached to the panel. The panel locking claws 10, 1
The tip portion of the zero is formed to be thin so that even a finger can bend inward in the radial direction. Therefore, the panel locking claws 10 and 10 can be bent inward in the radial direction to release the locking with the panel.

In the bolt receiving hole 9 of the shaft portion 8, bolt engaging claws 12, 12 for engaging with the screws of the received bolts are formed so as to face the panel engaging claws 10, 10 at right angles. ing. The bolt locking claw 12 is configured such that the bolt is in the receiving hole 9.
When the bolt is pulled out, it is formed to bend outward in the radial direction. The tip portions of the bolt locking claws 12, 12 correspond to the height of the screw thread of the bolt being shifted,
It is formed shifted. As described above, the shaft portion 8 is formed in a rectangular shape in a cross section (particularly, see FIG. 6), and its diagonal length is the diameter of the mounting hole 5 (shown in phantom lines in FIG. 6) of the panel. It is formed to be slightly smaller than. As a result, each corner portion comes into contact with the mounting hole 5, and the shaft portion 8
Can be fixed to the mounting hole 5. In this shaft section 8 having a rectangular cross section, panel locking claws 10 and 10 are formed on the long side, and bolt locking claws 12 and 12 are formed on the short side. In particular, since the panel locking claws 10 and 10 are formed on the long sides, the amount of inward bending of each panel locking claw 10 can be increased, thereby inserting the shaft portion 8 into the mounting hole of the panel. At this time, the panel locking claw 10 is largely bent to be out of the way, and the panel locking claw 10 is greatly bent inward in the radial direction, so that the panel locking claw 10 can be easily removed.

[0012] Bolt locking claws 12, 12 on the inner surface of the shaft portion 8
Between them, a pair of ribs 13 extending in the axial direction is formed. The ribs 13, 13 narrow the bolt receiving hole 9, and when the bolt is inserted into the receiving hole 9, the thread of the bolt bites into each rib 13. Accordingly, the locking force of the bolt locking claw 12 and the locking force of the rib 13 are applied, and the clip 1 is firmly fixed to the bolt. Further, the bolt locking claws 12, 1
In the case of engaging with the screw thread of the bolt at 2, the gap between the flange 7 of the clip 1 and the mounting part 2 is at most one pitch of the screw of the bolt. , So that the gap between the flange 7 of the clip 1 and the mounting component 2 is eliminated. The flange 7 is formed as a spacer that keeps the distance between the mounting component and the panel constant. In order to obtain a height as a spacer, the flange 7 has a configuration in which a disk portion 14 on the lower surface and a funnel-shaped portion 15 on the upper surface are connected at four places by reinforcing ribs 16. As a result, sufficient strength and light weight can be achieved, and plastic materials can be saved.

A component mounting structure and a component mounting method according to the present invention for mounting a mounting component 2 on which a bolt 3 is erected to a panel 4 using such a clip 1 are shown in FIGS.
This will be described with reference to FIG. In FIG. 7, the shaft 8 of the clip 1 is inserted into the mounting hole 5 of the panel 4 by a finger or the like in the direction of arrow 18. By this insertion, as shown in FIG.
And is attached to the panel 4. Next, as shown by the arrow 19 in FIG. 9, the bolt 3 of the attachment part 2 is inserted into the bolt receiving hole of the clip 1. By this insertion, FIG.
As shown in FIG. 0 and FIG. 11, the bolt 3 is engaged with the bolt locking claws 12, 12, and the component 2 is attached to the clip 1. As described above, since the clip 1 is attached to the panel 4, the component 2 is attached to the panel 4 by inserting the bolt 3 into the clip 1. In this mounting, the flange 7 of the clip 1 functions as a spacer for keeping the panel 4 and the component 2 at a constant height. Further, since the rib 13 (see FIG. 5) formed in the bolt receiving hole of the clip 1 bites into the thread of the bolt 3, the bolt 3 is firmly attached to the clip 1, and furthermore, the bolt locking claw 1
This eliminates the gap between the flange 7 of the clip 1 and the mounting part 2 which would otherwise be caused by the engagement of the screws 2 and 12 with the screws of the bolt 3 only. As described above, no tool is required for attaching the attachment component 2 to the panel 4.

In the component mounting structure and the component mounting method according to the present invention, the mounting component 2 can be easily removed from the panel 4. In this removal, as shown in FIG. 12, a finger is extended to the back surface of the panel 4 to deflect the panel locking claws 10 and 10 of the clip 1 inward in the radial direction, and Release from the engagement of 4. FIG.
As shown in FIG. 3, when the mounting part 2 is pulled up in the direction of the arrow 20, the part 2 is pulled up together with the part 2 while the clip 1 is mounted on the bolt 3, and the part 2 can be removed from the panel 4. After removal, if necessary,
By rotating the clip 1 as shown by the arrow 21 in FIG. 14, the clip 1 can be removed from the bolt 3. As described above, no tools are required for the work of removing parts.

In reattachment after removal, the bolt 3
When the clip 1 is removed from the panel 4, the component 2 can be attached to the panel 4 according to the procedure shown in FIGS. When the clip 1 is not removed from the bolt 3, that is, even when the clip 1 is attached to the bolt 3, the component 2 can be attached to the panel 4. In this case, the bolt 3 of the mounting component 2 to which the clip 1 is mounted may be inserted into the mounting hole 5 of the panel 4.

In the illustrated mounting method, a clip is mounted on a panel, and bolts of mounting parts are inserted into the clip. However, there are other mounting methods. That is, the clip may be attached to the bolt first, and the clip may be inserted into the attachment hole of the panel with the part to which the clip is attached.

[0017]

According to the present invention, no tools are required for mounting components on the panel, and no tools are required for removing the components and the clips can be easily formed without damaging the clips. It can be reused many times, and the work of reattaching parts is extremely simple. Also, since there are two types of mounting methods and two types of removing methods, a method according to the work can be used.
