It is possible to effectively absorb the bending of the web portion having a bellows shape and prevent the mechanical vibration generated on one side from being transmitted to the other side.

[0004]

However, in the conventional anti-vibration type clip, the use of the flexible bellows-like web portion as the vibration absorbing means is effective in absorbing mechanical vibration. Then, although a certain effect may be expected, on the other hand, the adoption of such a configuration is adversely affected, resulting in the following inconvenience.

That is, when the rod-shaped body is forcibly fitted into each cradle of the holding portion, the web portion is easily deformed by its own flexible form, and the rod-shaped body is smoothly moved into each cradle. Since it cannot be fitted, the efficiency of the work of fitting the rod-shaped body is naturally reduced, and even when the rod-shaped body is held, the web portion is easily deformed and the rod-shaped body is in the aligned state. There was a risk that it could not be held in the proper position.

[0006]

The present invention was developed in order to effectively solve the problem of the conventional vibration-proof clip, and the invention according to claim 1 holds a rod-shaped body.

[0013]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described below in detail with reference to the preferred embodiments shown in the drawings. As shown in FIG. 1, the vibration-proof clip according to the first embodiment includes a holding body 1 that holds a rod-shaped body, a fixing body 2 that connects the holding body 1 and is fixed to the panel side, and the fixing body. It consists of three parts, the vibration absorber 3 interposed between the connecting portion of the body 2 and the holding body 1.

The first holding body 1 is integrally formed of a synthetic resin in a rectangular shape to form a plurality of receiving bases 4 for holding the rod-shaped bodies in the longitudinal direction of the upper portion thereof. The downward elastic claws 5 are obliquely provided on both side edges in a paired relationship, while a connecting plate 6 parallel to the lower surface is integrally connected to the lower center through a neck piece 7.

The second fixed body 2 is integrally molded of synthetic resin and has a box portion 8 whose one side surface is open. The upper surface of the box portion 8 is communicated with the opening 8a, and the holding body is formed. While forming a slit 9 that allows passage of the neck piece 7 on one side, a pair of protrusions 10 are provided on both sides of the lower surface of the box portion 8 and are attached to an attachment hole formed in the panel at the center thereof. The anchor-shaped locking leg 11 is integrally hung.
However, the fixing means for the panel side, including the mounting hole, is not limited to this.

The third vibration absorber 3 is made of an elastic material such as synthetic rubber and is formed into a box shape with one side face similar to the box portion 8 of the fixed body 2 open, and the opening 3 is formed on the upper surface.
A slit 12 that communicates with a and allows the neck 7 on the holding body 1 side to pass is formed, and extends at the peripheral edge of the slit 12 at least by the upper wall thickness of the box portion 8 of the fixed body 2. The extension piece 13 is integrally formed. Since the vibration absorber 3 is set in the box portion 8 of the fixed body 2 described above, its box shape and slit shape are formed to be slightly smaller than those on the fixed body 2 side. .

Therefore, while the extension piece 13 of the vibration absorber 3 is exposed in the slit 9 formed in the box portion 8 of the fixed body 2, the vibration absorber 3 is opened in the box portion 8 from its opening 8a. When is inserted, the vibration absorber 3 is easily set in the box portion 8 on the fixed body 2 side with the opening 3a of itself and the opening 8a of the box 8 aligned. In addition, in such a set state, the extension piece 13 of the vibration absorber 3 fits into the slit 9 formed in the box portion 8 of the fixed body 2 to completely cover the circumferential surface of the slit 9. Becomes

Then, after that, while the neck piece 7 on the holding body 1 side is exposed in the slit 12 on the vibration absorbing body 3 side, the connecting plate of the holding body 1 is opened inside the vibration absorbing body 3 from its opening 3a. 6
As shown in FIG. 2, when the vibration absorber 3 is inserted, the holding body 1 and the fixed body 2 are immediately connected.

Therefore, when the long rod-shaped body 20 such as a brake pipe is aligned and held on the panel P side by using the vibration-proof clip having such a structure, the fixed body 2 in the connected state is locked. After the legs 11 cooperate with the projections 10 and engage with the mounting holes H pre-drilled in the panel P, the rod-shaped bodies 20 are forced into the respective pedestals 4 of the holding body 1 as in the conventional case. , The pressing action of the pair of elastic claws 5 is obtained, as shown in FIG.
The rod-shaped bodies 20 are held in a state of being aligned along the surface of the panel P.

However, when the rod-shaped body 20 is fitted into each of the receiving bases 4, a part of the clip is deformed as in the conventional case because the holding body 1 and the fixed body 2 have appropriate rigidity. There are no rods 20 on each pedestal 4.
It becomes possible to fit the clip smoothly, and there is no fear of reducing the efficiency of the fitting work. Moreover, even when the rod-shaped body 20 is held, a part of the clip can be easily deformed. Since there is no rod-shaped body 2 in the aligned state
There is no worry that 0 cannot be held at the proper position.

Further, when mechanical vibration is generated on the rod-shaped body 20 side or the panel P side while the rod-shaped body 20 is held, when the vibration is lateral vibration, the fixed body is fixed. Two
Can be absorbed by both side portions of the vibration absorber 3 set in the box portion 8 and the extension piece 13 covering the circumferential surface of the slit 9 of the box portion 8, and when the vibration is in the vertical direction, the vibration absorber 3 Since it can be absorbed by the upper and lower parts, it is possible to effectively prevent the mechanical vibration generated on the rod-shaped body 20 side or the panel P side from being transmitted to the other side.

In addition, as shown in the figure, if a constant gap 14 is defined between the lower surface of the holding body 1 and the upper surface of the box portion 8 of the fixed body 2, the holding body is allowed within the allowable range. Since 1 itself can freely swing in multiple directions via the neck piece 7, it is possible to effectively absorb movement and displacement of the rod-shaped body 20.

Further, under the first embodiment, as shown in FIGS. 4A to 4C, the box-shaped vibration absorber 3 bulges on both the outer surface and the inner surface, or on either the inner surface or the outer surface. If the parts 15 are formed with a certain interval, the vibration absorbing effect will be further improved, and as shown in D of the figure, one of the connecting plate 6 of the holding body 1 and the vibration absorbing body 3 will be formed. If the convex portion 16 is formed and the concave portion 17 that engages with the convex portion 16 is formed on the other side, the connecting plate 6 from the opening 3a of the vibration absorber 3 is formed.
It is possible to reliably prevent the slip-out of the.

Next, the anti-vibration clip according to the second embodiment will be described. In principle, the second embodiment also follows the first embodiment as it is. The difference is that the relationship between the box portion 8 and the connecting plate 6 in the first embodiment is reversed.

That is, in the second embodiment, as shown in FIG. 5, a box portion 8 whose one side surface is open is integrally connected to the lower portion of the holding body 1 and the lower surface of the box portion 8 is connected. A slit 9 that communicates with the opening 8a is formed in the upper side of the locking leg 11 of the fixed body 2, and a connecting plate 6 is connected to the upper portion of the locking leg 11 of the fixed body 2 via a neck piece 7. Forms a slit 12 communicating with the opening 3a on the lower surface, and extends the lower surface of the box portion 8 through the slit 9 formed in the box portion 8 of the holding body 1 with respect to the peripheral edge of the slit 12. The L-shaped extension piece 13 for covering is integrally formed.

Therefore, according to the second embodiment, while the slit 9 formed in the box portion 8 of the holding body 1 faces a part of the extension piece 13 of the vibration absorber 3, the box portion of the vibration absorbing body 3 is exposed. When the vibration absorber 3 is fitted into the opening 8a through the opening 8a, the vibration absorber 3 is inserted into the box portion on the side of the holder 1 with the opening 3a of itself and the opening 8a of the box portion 8 aligned. Easily set in 8. In this set state, the presence of the L-shaped extension piece 13 of the vibration absorber 3 covers not only the peripheral surface of the slit 9 of the box portion 8 but also the lower surface of the box portion 8. It will be.

Then, after that, the slit 1 of the vibration absorber 3
When the connecting plate 6 on the side of the fixed body 2 is fitted into the inside of the vibration absorber 3 from the opening 3a while the neck piece 7 on the side of the fixed body 2 is exposed to 2, the state in which the vibration absorber 3 is also present Then, the holding body 1 and the fixed body 2 are connected.

Therefore, when the long rod-like body 20 such as a brake pipe is aligned and held on the panel P side by using the vibration-proof clip having such a structure, the engagement on the fixed body 2 side in the connected state is performed. After the retaining leg 11 is attached to the mounting hole H of the panel P, if the rod-shaped body 20 is forcibly fitted into each receiving base 4 of the holding body 1,
As shown in FIG. 6, the pressing action of the pair of elastic claws 5 is obtained, and similarly, the rod-shaped bodies 20 are held in a state of being aligned along the panel P surface. Needless to say, the improved structure shown in FIG. 4 described above can be added to the second embodiment as well.

However, in this case, even when the rod-shaped body 20 is fitted into each of the pedestals 4 and the holding state of the rod-shaped body 20 is the same as in the first embodiment, the structure of the clip is similar to that of the first embodiment. Since there is no part of deformation, there is no concern that the efficiency of the fitting operation will decrease or that the rod-shaped bodies 20 in the aligned state cannot be held at the proper position.

When mechanical vibration occurs on the rod-shaped body 20 side or the panel P side while the rod-shaped body 20 is held, when the vibration is lateral vibration, the holding body is held. The extension piece 1 covering both sides of the vibration absorber 3 set in the box portion 8 of No. 1 and the peripheral surface of the slit 9 of the box portion 8.
3 can be absorbed by a part of the vibration absorber 3, and when the vibration is in the vertical direction, it can be absorbed by the upper and lower parts of the vibration absorber 3, the extension piece 13 interposed between the lower surface of the box portion 8 and the panel P surface. Also, it is possible to effectively prevent the mechanical vibration generated on the rod-shaped body 20 side or the panel P side from being transmitted to the other side.

[0031]

As described above, according to the present invention, by adopting the above configuration, even when the rod-shaped body is fitted into the pedestal,
Also, even under the holding condition of the rod-shaped body, due to its structure,
As in the conventional case, a part of the clip is not deformed, so that there is no fear that the efficiency of the fitting work will be reduced or that the rod-shaped body in the aligned state cannot be held at the proper position. In addition, it is needless to say that connecting the holding body and the fixed body with the vibration absorbing body interposed therebetween is excellent in the vibration absorbing ability, but the box portion and the vibration absorbing body are unitized to form a reference part. Therefore, it can be used for holding bodies and fixed bodies of different types, which is extremely economical.

Further, according to claims 2 and 5, the presence of the extension piece can be expected to provide a reliable anti-vibration effect, and under claim 3, the holder itself can freely move through the neck piece. Since it is possible to swing, it is possible to effectively absorb the movement and displacement of the rod-shaped body.
