[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting tool and a stud clip for mounting a mounting member on a member to which a stud bolt is erected.

[0002]

2. Description of the Related Art As shown in FIG. 7, when a seat member 50 is mounted on a vehicle body 12, a stud bolt 14 is inserted into a mounting hole 52 formed in the seat member 50, and a clip 54 is attached to the stud bolt 14. Put on the sheet material 5
It is designed to fix 0 (Actual number 62-4541).
No. 2).

The clip 54 has a circular substrate 56 placed on the body 12, and a cylindrical body 58 standing upright from the substrate 56. A claw 60 protruding toward the center is formed on the outer peripheral wall of the cylindrical body 58, and the claw 60 engages with the thread of the stud bolt 14 to fix the clip 54 to the stud bolt 14. ing.

At the top of the cylinder 58, there is provided a holding plate 64 which is folded with the thin portion 62 as a boundary.
By engaging the projection 68 projecting from 6 with the engaging hole 72 formed in the lower plate 70, the holding plate 64 is folded and expanded to the left and right, and the sheet material 50 is sandwiched between the body 12 and the body 12. It is supposed to do.

By the way, in this clip 54, since the claw 60 protruding to the center is provided, the rectangular opening 74 is inevitably formed on the outer peripheral surface of the cylindrical body 58 for the convenience of molding.

However, if there is such an opening 74,
Sound is transmitted from the body 12 to the passenger compartment through the stud bolt 14. Further, when the sheet member 50 is replaced, the claw 60 cannot be separated from the stud bolt 14 unless the cylindrical body 58 is rotated, which is troublesome.

[0007]

SUMMARY OF THE INVENTION In consideration of such a fact, the present invention shuts off the sound transmitted from the stud bolt, and
It is an object to make it easy to replace sheets.

[0008]

According to the first aspect of the invention, when the hollow portion of the soft cap is press-fitted into the stud bolt projecting from the member to be attached, the hollow portion is deformed and the thread of the stud bolt is screwed. It bites and the soft cap is fixed to the stud bolt.

A locking body is formed on the outer peripheral portion of the soft cap, and the mounting member is provided with a locking portion to be locked by the locking body so that the mounting member can be mounted on the stud through the soft cap. It is fixed to the bolt.

Here, the stud bolt is completely covered with the soft cap, and since it is not necessary to extend the locking body to the hollow side, it is not necessary to provide an opening for die cutting. . Therefore, the sound transmitted from the stud bolt can be blocked.

According to the second aspect of the present invention, after the mounting hole formed in the mounting member is inserted into the stud bolt projecting from the mounted member, the soft cap is press-fitted into the stud bolt. Next, when the tubular body is inserted into the soft cap, the locked body of the tubular body is locked by the locking body of the soft cap, and the tubular body is fixed to the soft cap. This cylindrical body has a bulge protruding in the radial direction, and this flange presses the surface of the mounting member and fixes the mounted member between the flange and the mounting member.

Here, since the locked body of the cylindrical body is only locked to the soft locking body, it can be removed from the soft cap by simply pulling it out without rotating the cylindrical body. Therefore, it is possible to easily replace the mounted member.

According to the third aspect of the invention, the locking body is a claw and the locked body is a locking hole. Therefore, when the tubular body is pushed into the soft cap, when the claw elastically deforms and corresponds to the locking hole, it elastically restores and locks the locking hole. Further, when the tubular body is pulled out, the claw elastically deforms and separates from the locking hole.

By setting the frictional engagement force between the stud bolt and the soft cap to be larger than the locking force between the claw and the locking hole, only the tubular body can be removed from the soft cap. Also, the soft cap can be removed from the stud bolt by turning it.

[0015]

BEST MODE FOR CARRYING OUT THE INVENTION As shown in FIGS. 1 and 2, a stud clip 10 according to the present embodiment includes a connector 16 press-fitted from a body 12 to a stud bolt 14 provided upright.
A clip 18 that is inserted and locked in the connector 16 is provided.

The connecting member 16 is formed of a soft member in the shape of a cylindrical cap, and a ring-shaped rib 20 is formed on the outer peripheral surface thereof.
Are extended in the circumferential direction at predetermined intervals in the axial direction. At the lowermost stage of the rib 20 provided in this step shape, a claw 22 is provided so as to project outward.

On the other hand, as shown in FIG. 3, a plurality of fins 24 project radially from the inner peripheral wall toward the center of the lower surface of the connector 16, and the top portion 26 is processed into a bowl shape from the lower surface.
Extending to The inside of the circle connecting the tips of the fins 24 is a hollow portion 28 into which the stud bolt 14 is press-fitted.

The clip 18 also has a tubular body 30 which is inserted into the connector 16. An engagement hole 32 that is engaged with the claw 22 is opened on the outer peripheral surface of the lower portion of the cylindrical body 30. In this way, since the locking hole 32 is locked by the claw 22 that projects outward, it is not necessary to provide an opening for die cutting in the connecting tool 16, and the sound transmitted from the stud bolt 14 is eliminated. Can be shut off.

On the other hand, on the upper portion of the cylinder 30, a flange 34 is projected in the radial direction. A ring-shaped protrusion 36 is provided on the lower surface of the flange 34 so as to bite into the surface of an insulator 38 described later.

Next, the stud clip 10 according to this embodiment.
The operation of will be described. As shown in FIG. 4, when the hollow portion 28 of the connector 16 is pressed into the stud bolt 14, the fin 24
While the stud bolt 14 is deformed, the stud bolt 14 is taken in, and the thread of the stud bolt 14 cuts into the fin 24 as shown in FIG. As a result, the connecting tool 16 causes the stud bolt 1
The sound transmitted through the stud bolt 14 is blocked.

Next, the mounting hole 40 formed in the insulator 38 is inserted into the stud bolt 14, and the tubular body 30 of the clip 18 is inserted into the connector 16 from above. As a result, as shown in FIG. 5, the locking hole 32 is locked to the claw 22, the clip 18 is fixed to the stud bolt 14, and at the same time, the flange 34 presses the surface of the insulator 38 and fixes it to the body 12. At this time, the protrusion 36
Since the bite bites into the insulator 38, the insulator 38 does not shift.

Further, the rib 20 is pushed downward by the friction with the cylindrical body 30 and exerts a force for stiffening, in other words, a force for eliminating the looseness between the claw 22 and the locking hole 32.

On the other hand, when replacing the insulator 38, the flange 34 can be detached from the connector 16 simply by grasping the flange 34 and pulling out the tubular body 30. That is, since it is not necessary to rotate the clip 18, it is possible to easily reattach the insulator 38.

In the present embodiment, since the frictional engagement force between the stud bolt 14 and the connecting tool 16 is set to be larger than the engagement force between the claw 22 and the engagement hole 32, only the clip 18 can be removed. It looks like this, but the connector 1
6 can be removed from the stud bolt 14 by turning.

If the frictional engagement force is set to be smaller than the locking force, the clip 16 as well as the connector 16 can be removed from the stud bolt 14.

Further, in this embodiment, the fin 24 forms the hollow portion 2.
However, a circular hole may be simply formed, and a locking groove (a depth that does not penetrate into the hollow portion 28) is formed on the connecting tool 16 side and a clip 18 side is formed. A claw that is locked in this locking groove may be provided.

[0027]

Since the present invention has the above-mentioned structure, the sound transmitted from the stud bolt can be shut off, and the replacement work of the sheet material can be easily performed.
