Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clip for connecting a mounting member such as a silencer, a heat insulating plate, a decorative plate, or a mat to a second mounting member such as a body panel, and more particularly to a shaft portion and one end of the shaft portion. Is fixed to the first mounting member by a flange formed on the side of the shaft and a locking means provided on the other end side of the shaft portion, and the second locking means provided on the shaft portion is fixed to the second mounting member. The present invention relates to a clip that connects both attachment members by locking them.

[0002]

2. Description of the Related Art A clip for connecting a first mounting member such as a silencer, a heat insulating plate, a decorative plate, and a mat to a second mounting member such as a body panel is disclosed in, for example, Japanese Utility Model Publication No. 1-241818. The clip is fixed to the first mounting member by a shaft portion, a flange formed on one end side of the shaft portion, and a pair of locking wings provided on the other end side of the shaft portion. The two mounting members are connected to each other by locking a stud locking claw provided on the shaft portion in a state of being fixed to a stud standing on the second mounting member. Since this clip is fixed to the first mounting member by opening and closing the pair of locking wings, there is an advantage that the work is easy and the removal work is also easy.

[0003]

However, in order to fix the clip to the first mounting member, the shaft portion is inserted into the mounting hole of the first mounting member and the flange is kept in contact with the mounting member. However, it is difficult to work from one side of the mounting member because the locking wing on the other end of the shaft portion must be tilted in the opening direction.

Therefore, an object of the present invention is to provide a clip which can be easily fixed to a mounting member by a work from one side and has a sufficient holding force after fixing.

[0005]

To achieve the above object, according to the present invention, a shaft portion, a flange formed on one end side of the shaft portion, and a flange provided on the other end side of the shaft portion are provided. A clip which is fixed to a first mounting member by means of a first locking member and which connects the first mounting member to a second mounting member such as a body panel using a second locking member provided on the shaft portion. An elastic support arm extending from a position close to the flange along the shaft to near the other end of the shaft is formed in the portion, and is radially outward of the shaft from the vicinity of the tip of the support arm. A locking arm extends obliquely to the side of the flange, and the locking arm forms the first locking means, and the support arm is inserted into the mounting hole of the first mounting member in the shaft portion. Is provided with a space that allows the inside to bend inward in the radial direction. -Up is provided.

[0006]

[Function] Since the locking arm extends in a hook shape from the support arm, when the shaft portion is inserted into the mounting hole of the mounting member such as the silencer with the tip of the support arm at the head, the hook is smoothly inserted with the hook closed. When the flange is brought into strong contact with the mounting member, the locking arm opened from the mounting hole opens into a hook shape and locks on the other surface of the mounting member, whereby the clip is fixed to the mounting member. . Therefore, the clip can be easily fixed by the work from one side of the mounting member.

In the present invention, a rib can be formed at the connecting portion between the supporting arm and the locking arm to strengthen the connecting portion. A pair of support arms and locking arms may be formed at positions diametrically opposed to the shaft portion, one support arm and one locking arm may be formed, and the locking arms may be formed on various plates of the mounting member. A plurality of overhangs may be formed to extend from the support arm to accommodate the thickness. The shaft portion may be formed hollow so as to receive the stud provided upright on the second mounting member, and a locking claw for locking the stud may be formed inside the shaft portion as the second locking means. Further, as the second locking means, an anchor leg type locking means may be provided at the one end of the shaft portion for locking by being inserted into the mounting hole of the second mounting member. In this case, after mounting the clip on the first mounting member, a cap that prevents the support arm and the locking arm from bending inside the shaft portion can be inserted into the other end of the shaft portion. And
It is also possible to close the other end of the shaft. Further, the locking arm may be provided with a stopper surface that abuts on the edge portion of the head portion at the other end of the shaft portion and limits the opening angle of the locking arm. Further, the shaft portion is formed by a pair of elastic support arms extending from the vicinity of the flange to the other end, and the locking arm is extended from the support arm in a hook shape, and one of the connecting portions of the supporting arm and the locking arm is connected to the other. A cover may be formed at the connecting portion of the cover to close the space between the connecting portions, a first hinge may be formed at both connecting portions of the cover, and a second hinge may be formed at the center of the cover. As a result, not only the sound insulation effect but also the locking arm and the cover are integrated to facilitate the insertion.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. First, in FIGS. 1 to 6, the clip 1 is an integrally molded product of plastic, and has a shaft portion 2 and a flange 3 formed on one end (lower end) side of the shaft portion. The shaft portion 2 is formed in a hollow shape so as to receive a screw stud provided upright on a body panel or the like. A head portion 5 is provided on the upper end of the shaft portion 2. Flange 3 of shaft 2
In the portion adjacent to, the locking claw 6 that locks to the screw stud
Are formed in pairs. The locking claws 6 may be formed at the same height as shown in FIG. 6, but may be displaced according to the screw pitch of the screw stud as shown in FIG. A pair of projections 7 elongated in the axial direction are formed inside the shaft portion 2 so as to eliminate rattling with the received stud. Further, the flange 3 is formed in a trumpet shape opened from the hole of the shaft portion 2 and an edge portion 9 thereof is formed in an upright wall in order to facilitate picking up a stud that may be slightly displaced.

An elastic support arm 10 extending from the position near the flange 3, that is, the position where the locking claw 6 is formed, to the other end along the shaft 2, that is, near the upper end, is provided on the shaft portion 2 in the diameter direction of the shaft portion. A pair is formed at a position facing each other. The support arm 10 has elasticity, and the shaft portion 2 is formed of a pair of elongated column members so as to form a space inside which the support arm 10 is allowed to bend. From the tip (upper end) of each support arm 10, a locking arm 11 extends outward in the radial direction of the shaft portion and extends obliquely downward in a hook shape. The locking arm 11 serves as locking means for locking a mounting member such as a silencer or a heat insulating plate, and functions to fix the clip 1 to the mounting member in cooperation with the flange 3. The locking arm 11 is preferably long in terms of mounting strength after fixing, but short in terms of insertability into a mounting member. In the present invention, since the support arm 10 supporting the locking arm 11 flexes sufficiently to the inner side of the shaft portion, even if the locking arm 11 is lengthened, the supporting arm 10 flexes sufficiently to the inside, and the workability of inserting the clip shaft portion is improved. Since it does not damage, the locking arm 11 can be lengthened, a sufficient locking portion to the mounting member can be secured, and the mounting hole of the mounting member can be made small. Note that, as shown in FIG. 7, ribs 12 may be provided at the connecting portion between the support arm 10 and the locking arm 11 to strengthen the connecting portion.

9 and 10 show an example of a clip having no locking claw for locking the stud. In this example,
Instead of the locking claw 6, on the inner wall of the shaft portion near the flange,
Three protrusions 13 extending in the axial direction are formed. The length of protrusion of the protrusion inward is such that the thread of the stud bites into the stud when the protrusion is pressed. The protrusion 13 provides a higher attachment force than the locking claw.

The operation of connecting the first mounting member such as the silencer to the second mounting member such as the body panel using the clip 1 having the above structure will be described with reference to FIGS. 11 to 13. In FIG. 11, the head portion 4 of the shaft portion 2 of the clip 1
Starting from, the shaft portion is inserted into the mounting hole 15 of the first mounting member 14. By this insertion, the support arm 10 bends inward of the shaft portion, so that the connecting portion of the locking arm 11 also enters inside, and the tip of the locking arm 11 also flexes. In this way, not only the locking arm 11 but also the support arm 10 is sufficiently tilted to the inner side of the shaft portion, so that the insertion into the mounting hole can be sufficiently performed with a weak force. When the clip shaft portion is inserted until the flange 3 comes into contact with the first mounting member 14, the locking arm 11 is exposed on the upper surface of the first mounting member 14. 12
As shown in FIG. 6, when the locking arm 11 is released from the first mounting member 14, not only the locking arm 11 but also the support arm 10
Also returns to its original posture due to its elasticity, and the locking arm 1
1 opens in a hook shape and locks on the upper surface of the first mounting member 14. As a result, the clip 1 is fixed to the first mounting member 14.

After fixing one or a plurality of clips 1 to the first mounting member 14, the clip 1 is carried to a place where a second mounting member 17 such as a body panel for connecting the first mounting member 14 is provided. A plurality of screw studs 18 are erected on the second mounting member 17 at predetermined positions. The operator picks up the stud by the upright wall of the flange 3 with the first mounting member 14 with the clip, and presses the clip 1 on the stud as it is. By this pressing, the stud 17 is retained in the clip shaft portion 2 while being retained by the retaining claw 6, and the protrusion 7 (see FIG.
(Refer to FIG. 13), it enters while being regulated, and the final mounting state of FIG. 13 is reached. In this state, the first mounting member 14
It is connected to the mounting member 17. In this connected state, since the stud 17 is contained in the shaft portion 2, the support arm 1
0 can no longer bend inward. Therefore, the movement of the locking arm 11 to the inside of the shaft portion 2 is restricted, so that the locking force of the locking arm 11 is maintained high and the disengagement prevention of the clip 1 is strengthened.

14 and 15 show an example of a clip formed so as to project a plurality of locking arms from a support arm. In the illustrated example, the support arm 10 and the second locking arm 20 are formed below the locking arm 11.
As a result, in the case of the thick mounting member 14 of FIG.
If the first locking arm 11 is used and the thin mounting member 14a of FIG. 15 is used, the second locking arm 20 is used to accommodate different mounting member thicknesses. Further, in the case of this multi-stage locking arm configuration, in the case of FIG. 15, the first locking arm 11 is released even if the locking of the second locking arm 20 is released.
Can be locked. The number of the locking arms 11 is not limited to one pair, and may be only one as shown in FIG. In this case, the shaft portion 2 can be formed in a simple semi-cylindrical shape on the side without the locking arm.

17 to 20 show an example of a clip in which the hole in the head of the shaft portion is closed. That is, the head 21 is formed as a non-perforated plate, which can shield noise from the body panel and the like. Then, as compared with the perforated plate, the pressing area for insertion is increased, and there is an advantage that the pressing is facilitated. Further, since the hole is not formed in the head portion 21, its strength is increased, and the column member forming the shaft portion can be made thin. As shown in FIG. 20, the shaft portion 23 is made thin and point-symmetrical about the axis. Can be formed into This simplifies the construction of the mold.

In FIGS. 21 to 24, the locking means for the second mounting member such as the body panel is locked by being inserted into the mounting hole of the second mounting member instead of the locking claw for the stud. The example of the clip formed of the anchor type | formula locking means is shown. In the example of this clip, the shaft portion 2, the support arm 10, and the locking arm 11 are the same as those of the clip 1, and therefore their explanations are omitted. The flange 24 is slightly different in shape, but is the same in that it is held in contact with the first mounting member 14. At the lower end of the shaft portion 2, an anchor leg type locking portion 28 including a pair of anchor leg-shaped locking claws 25 and a central plate-shaped shaft portion 27 is provided. As shown in FIG. 24, the locking claw 25 is formed so as to bend toward the plate-shaped shaft portion 27, and is locked by being inserted into the mounting hole of the second mounting member. The second flange 29 below the flange 24 has elasticity to prevent rattling when mounting the second mounting member. Since the stud is not inserted in the shaft portion 2 of this clip, the support arm 1 is not removed even after mounting.
There is a fear that 0 bends inward of the shaft portion 2. Therefore, the shaft portion 2
25, the cap 31 shown in FIG. 25 is inserted into the hole of the head 5. The upper surface of the cap 31 is square (or rectangular)
And a lower portion formed in a cylindrical shape, and a pair of protrusions 32 are formed on the upper plate and the lower tubular body, respectively.
33 is formed.

The mounting operation will be described with reference to FIGS. The cap 31 is attached to the head of the shaft portion 2 by engaging the lower protrusion 33 with the clip as shown in FIG. Next, the clip is attached to the first attachment member 14,
It is fixed through the procedure of FIGS. 27 and 28. The first attachment member 14 to which the clip is fixed is carried to the second attachment member 17, and the anchor leg locking portion 28 of the clip is attached to the second attachment member 17.
Aligned with the mounting hole of and pushed in. As a result, FIG.
As shown in the drawing, the anchor leg type locking claws 25, 25 are locked to the back surface of the second mounting member 17, and the first mounting member 14 is connected to the second mounting member 17. After connection, the cap 31 has an arrow 35.
The protrusion 32 of the cap 31 is locked and fixed to the inner wall of the head. Thereby, the support arm 1
0 is prevented from flexing inward, so that the locking arm 11 is locked.

30 to 34, a clip 37 having a different structure is shown. In the clip 37, the shaft portion 38 has a portion 40 where the stud locking claw 39 is formed.
Above that, it is formed by a pair of elastic support arms 41. From the tip of each support arm 41, the clip 1
Similarly, the locking arm 42 is formed so as to project in a hook shape. In this clip 37, since the space between both the connecting portions from one connecting portion between the supporting arm 41 and the locking arm 42 to the other connecting portion is closed, the cover 43 is provided.
Are formed. A first hinge 45 is formed on each of the connecting portions of the cover. Further, a second hinge 46 is formed at the center of the cover 43. The cover 43 can block noise from the body panel and the like.

By using the clip 37 having the above structure,
As shown in FIG. 35, the cover 43 is first inserted into the mounting hole of the first mounting member 14. By this insertion, the cover 43 bends around the second hinge 46 and becomes smaller than the mounting hole, and the locking arm 42 also rotates around the first hinge 45 and becomes smaller than the mounting hole, which makes it extremely easy to enter. Further, since the surface of the cover 43 is continuous with the engaging arm 42, the insertion into the mounting hole is further facilitated. As shown in FIG. 36, when the shaft portion 38 is inserted until the flange 47 comes into contact with the first mounting member 14, the locking arm 42 comes out and locks on the upper surface of the first mounting member 14.
As a result, the clip 37 is fixed to the first mounting member 14. At this time, the first hinge 45 and the second hinge 46
Limits the opening of the locking arm 42, so that the locking force is strongly maintained. Next, as shown in FIG. 37, the first attachment member 14 with a clip is attached to the second attachment member 1
The clip 37 is pressed against the stud 18 of 7. By this pressing, the stud 17 enters through the clip shaft portion 38, the stud 17 is locked to the locking claw 39, and the first mounting member 14 is connected to the second mounting member 17. The stud 1 is provided between the shaft portion 38 and the support arm 41.
Since 7 is included, the support arm 41 cannot bend inward. Therefore, the locking force of the locking arm 42 is maintained high, and the clip is prevented from coming off. The first hinge 45 may be provided at the connecting portion between the support arm 41 and the locking arm 42.

38 to 39 show a clip 49 having a different structure. In FIG. 38, the clip 49 is very similar to the clip 1 shown in FIGS. 1 to 6, but the head 51 of the shaft portion 50 is different in the configuration that regulates the opening angle of the locking arm 53, Other configurations are the same. In this clip 49, a stopper surface 55 that contacts the edge of the head 51 is formed at the connecting portion of the locking arm 53 with the support arm 54. The stopper surface 55 contacts the edge of the head 51 when the locking arm 53 is opened beyond a certain angle, and restricts it from opening any further. Therefore, the clip 49 is prevented from coming off from the first mounting member such as the silencer supported by the locking arm 53 and the flange 57. This is shown in FIG. When the clip 49 is attached to the first attachment member 58 and the pulling force is applied to the first attachment member 58 as shown by the imaginary line in the figure, the locking arm 53 opens to the position of the imaginary line. However, the stopper arm 55 of the locking arm abuts against the edge of the head 51 and prevents further opening. Therefore, the first
Even if a pulling force is applied to the attachment member 58, the opening of the locking arm 53 is restricted, and the clip 49 is prevented from coming out.

[0020]

According to the present invention, the shaft portion is formed with an elastic support arm extending from the flange side along the shaft portion to the vicinity of the tip of the shaft portion. The locking arm extends obliquely to the side of the flange toward the flange, and the shaft portion is provided with a space that allows the support arm to bend radially inward when inserted through the mounting hole of the first mounting member. Therefore, if you insert the shaft into the mounting hole of the mounting member such as the silencer with the tip of the support arm at the top, you can insert it smoothly with the hook-shaped locking arm closed, and you can insert it even with a small insertion force. When the flange is brought into strong contact with the mounting member, the locking arm opened from the mounting hole opens in a hook shape and locks on the other surface of the mounting member.
As a result, the clip is fixed to the mounting member. Therefore, the clip can be fixed simply by working from one side of the mounting member without requiring a strong force. After the attachment to the second attachment member, the bending of the support arm is prevented by the stud, the cap, or the like, so that the engagement force of the engagement arm is greatly improved. As a result, a clip that can be easily fixed to the attachment member by a work from one side and that has sufficient holding force after fixation is provided.
