Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to holding a long rod-shaped body such as a brake pipe used in an anti-lock brake system of an automobile, an accelerator pedal wire, a fuel pipe or the like while absorbing vibration. The present invention relates to an improvement of a vibration-proof clip that can be performed.

[0002]

2. Description of the Related Art As a conventional clip of this type, Japanese Patent Application Laid-Open No.
-310866 gazette exists. Although not specifically shown, the conventional vibration-proof clip is a synthetic resin integrally-molded product, and includes a fixing portion fixed to a stud bolt embedded in a panel and a rod-shaped body such as the brake pipe described above. It is composed of a holding part having a plurality of pedestals each having a lateral C shape for holding, and a bridge part having a closed ring with high flexibility, and the fixing part and the holding part are vertically arranged via the bridge part. It is configured to be integrally connected to.

In actual use, when the fixing portion is fixed to the stud bolt on the panel side and the rod-shaped body is forcibly fitted into each cradle of the holding portion, a long rod-shaped body is obtained. Is kept aligned along the panel surface,
Further, under such a condition, when mechanical vibration is generated on the rod-shaped body side or the panel side, the vibration is effectively absorbed by the bending of the bridge portion having a closed ring shape with high flexibility. Thus, it is possible to prevent the mechanical vibration generated on one side from being transmitted to the other side.

[0004]

However, in the conventional anti-vibration type clip, it is necessary to use the bridge portion having a closed ring with high flexibility as the vibration absorbing means in order to absorb mechanical vibration. Then, it may be possible to expect some effect, but on the other hand, the adoption of such a configuration is contradictory,
The following inconveniences have been introduced.

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

[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 has rising walls on both sides. A base body having the base body, a support body for supporting a rod-shaped body formed on the upper surface of the base body, the support body supported between the ascending walls of the base body, and a sleeve-shaped vibration absorber connecting the support body and the base body. The vibration absorber has a structure in which the base body and the holding body are connected to each other so as to be capable of relative swinging along the longitudinal direction of the rod-shaped body held by the holding body under a pressed state.

According to a second aspect of the present invention, based on the first aspect, the sleeve shape of the vibration absorber is such that the assembling angle between the base body and the holding body can be determined when the base body and the holding body are assembled. A configuration was adopted in which both the outer peripheral side and the inner peripheral side had a shape other than a circular shape.

According to a third aspect of the present invention, based on the first and second aspects, the vibration absorber has an enlarged collar portion provided at one end of the sleeve shape and interposed between the rising wall of the base body and the end surface of the holding body. Adopted the configuration.

According to a fourth aspect of the present invention, based on the first to third aspects, the base body has a fixing means for fixing to the fixing member side, and the shaft center of the rod-shaped body held by the holding body. However, a configuration is adopted in which it is set at a position farther from the fixing means of the base than the sleeve-shaped axis of the vibration absorber.

According to a fifth aspect of the present invention, based on the first to third aspects, the base body has a fixing means for fixing to the fixing member side, and the shaft center of the rod-shaped body held by the holding body. And a sleeve-shaped shaft center of the vibration absorber are set to be at the same position from the fixing means of the base body.

According to a sixth aspect of the invention, based on the first to third aspects, the base body has a fixing means for fixing to the fixing member side, and the shaft center of the rod-shaped body held by the holding body. However, a configuration is adopted in which the vibration absorber is set to a position closer to the fixing means of the base than the sleeve-shaped axis of the vibration absorber.

Therefore, in the present invention, the clip itself can be easily integrated by connecting the base body and the holding body via the sleeve-shaped vibration absorber so as to be relatively swingable. Therefore, when holding a long rod-shaped body, as in the conventional case,
When the rod-shaped body is forcibly fitted into the cradle of the holding body, the rod-shaped body is held on the holding body side. Even underneath, due to its structure, part of the clip does not easily deform unlike the conventional case, so the efficiency of the fitting work decreases and the rod-shaped body in the aligned state is held at the proper position. There is no worry that you will not be able to do it.

In particular, according to claim 1, even if the rod-shaped body is held in a tilted state, or even if the rod-shaped body is bent and tilted by vibration, the holding body can be swung to follow the inclination. , If there is no concern that the rod-shaped body will come off from the holding body or frictional wear, and the holding body will follow and tilt,
The vibration absorber in the pressed state works to suppress the vibration of the rod-shaped body. According to the second aspect, since the force in the direction of returning the holding body tilted from the vibration absorber to the desired assembly angle is obtained, the tilting and vibration of the holding body can be suppressed.

Further, according to the third aspect, it is possible to effectively absorb the vibration due to the swinging of the holding body and prevent the generation of the tapping sound between the base body and the holding body. According to the fourth aspect, even if the holding body is tilted due to the expansion and contraction of the rod-shaped body, the vibration absorber works to suppress the expansion and contraction vibration of the rod-shaped body. Claims 5 and 6
Since the holding body and the rod-shaped body can be held close to the fixing member side under the lower part, it is possible to effectively reduce vibrations and loads applied to the base body, improve durability, and miniaturize the clip itself.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail with reference to the preferred embodiments shown in the drawings. A vibration-proof clip according to the present embodiment, as shown in FIG.
Having a U shape and having a U shape, and a holding body 2 having a rectangular shape supported between the compatible upward walls 1a and 1a of the base body 1.
And a sleeve-shaped vibration absorber 3 for connecting the holding body 2 and the base body 1 to each other.

The first base body 1 is integrally molded of synthetic resin to form an elliptical fitting hole 4 in the central portion of the ascending wall 1a, while forming a panel in the central portion of the lower surface. An anchor-shaped locking leg 5 and an umbrella-shaped flange 6 that engage with the mounting hole are integrally connected. However, the fixing means for the panel side, including the mounting hole, is not limited to this.

The second holding body 2 is also integrally molded of synthetic resin to form a plurality of receiving bases 7 for holding the rod-shaped bodies in the longitudinal direction of the upper surface thereof, and both side edges of the respective receiving bases 7. The downwardly facing elastic claws 8 are obliquely provided in a paired relationship, while the connecting shafts 9 having an elliptical cross section which are press-fitted into the vibration absorber 3 are formed on both end surfaces. The connecting shaft 9 is formed so as to be orthogonal to the alignment holding direction of the rod-shaped bodies held by the respective pedestals 7 having the horizontal C shape.

The third vibration absorber 3 is made of an elastic material such as synthetic rubber and is shaped like a sleeve. The outer periphery of the third vibration absorber 3 is an ellipse similar to the elliptical shape of each fitting hole 4 of the base 1. The shape is positively given, and an elliptical shape similar to the elliptical shape of each connecting shaft 9 of the holding body 2 is positively given to the inner circumference, while each rising of the base body 1 at the inner end side. An enlarged brim portion 10 interposed between the wall 1a and the end surface of the holding body 2 is integrally formed, and a groove 11 for locking the edge of the fitting hole 4 is formed on the outer peripheral surface.

Accordingly, with the enlarged flange portion 10 positioned inside, the vibration absorber 3 is fitted into the fitting hole 4 formed in the compatible upward wall 1a of the base body 1, and then the respective vibration absorbers are fitted. When the connecting shaft 9 on the holding body 2 side is press-fitted into the inside of FIG.
As shown in FIG. 5, each of the vibration absorbing members 3 is controlled by the elliptical shape so that the base member 1 and the holding member 2 have a predetermined assembling angle.
, And thereby the clip itself is integrated. In this case, first, the connecting shaft 9 of the holding body 2 is press-fitted into the vibration absorber 3 and then the vibration absorber 3 is fitted into the fitting hole 4 of the base body 1. Is also possible.

However, in any case, in the integrated state, each vibration absorber 3 has a fitting hole 4 on the base 1 side and a holding body 2.
Is pressed between the connecting shafts 9 and the enlarged flange portion 10 is
As shown in the drawing, the rising wall 1a of the base body 1 and the end surface of the holding body 2 are interposed in a sliding contact state. Further, under the present embodiment, the axis A of the rod-shaped body held by the holding body 2 is
However, it is set at a position farther from the locking leg 5 of the base 1 than the sleeve-shaped axis B of the vibration absorber 3.

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 bottom surface of the base body 1 in an integrated state is fixed. After the provided locking legs 5 cooperate with the flanges 6 and engage with the mounting holes H pre-drilled in the panel P, the locking legs 5 are placed in the respective receiving bases 7 of the holding body 2 as in the conventional case. When the rod-shaped bodies 20 are forcibly fitted, as shown in FIG. 3, the rod-shaped bodies 20 are held in a state of being aligned along the surface of the panel P by the pressing action of the pair of elastic claws 8.

However, when the rod-shaped body 20 is fitted into each of the receiving bases 7, a part of the clip may be deformed as in the conventional case because the base body 1 and the holding body 2 have appropriate rigidity. Moreover, since the holding body 2 itself does not inadvertently incline with respect to the base body 1 due to the restriction of each elliptical shape, it becomes possible to smoothly fit the rod-shaped body 20 into each cradle 7. There is no concern that the efficiency of the fitting operation will decrease, and since the clip does not easily deform even when the rod-shaped body 20 is held, the rod-shaped body 20 in the aligned state can be properly processed. There is no worry that you will not be able to hold it in a proper position.

Further, 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, in particular, It can be absorbed by the enlarged flange portion 10 of the vibration absorber 3 interposed between each rising wall 1a of the base body 1 and the end surface of the holding body 2, and is fitted into each fitting hole 4 when the vibration is in the vertical direction. Vibration absorber 3
Since it can be absorbed by itself, in any case, 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 this case, U of the base 1
Although the bending obtained from the character shape is also useful for absorbing vibration, the expanding flange portion 10 is urged toward the end surface side of the holding body 2 by the elastic action of each rising wall 1a of the base body 1. Therefore, also by this, the vibration absorbing function is further enhanced.

Further, according to the present embodiment, since the vibration absorber 3 is softer than the holder 2, the vibration absorber 3 is deformed when absorbing the vibration, but the holder 2 is very small. Since it is only deformed, even if the holding body 2 is repeatedly bent and deformed, the abrasion of the pedestal 7 is not promoted, and thus the high holding force of the rod-shaped body 20 can be maintained.

Furthermore, when the held rod-shaped body 20 is tilted due to vibration or the like, the vibration-absorbing body 3 is deformed as shown in FIG. It is possible to effectively avoid applying an unreasonable external force to the rod-shaped body 20 while swinging relative to the base body 1 by an amount corresponding to the inclination so as to maintain the same vibration-proof state, and the inclination of the rod-shaped body 20 is released. In the case where it is broken, it is possible to use the reaction force of the vibration absorber 3 to return the holder 2 to the predetermined assembly angle position.

When the brake hydraulic pipe of the anti-lock brake system is held, the brake is weakened when the brake lock of the tire is detected, and conversely, the brake is strengthened when it is detected that the brake lock of the tire is released. As described above, when pulsation with high hydraulic pressure occurs in the pipe, pulsating vibration due to the water hammer phenomenon occurs inside the pipe, and high-frequency vibration is propagated inside and outside the vehicle through the panel P. However, even in such a case, the noise generated can be reduced by the action of the vibration absorber 3.

Further, when a resin fuel pipe of an automobile is held, if a pressure fluctuation occurs due to discharge pulsation of the resin fuel pipe or sudden opening / closing of a fuel injection valve, the resin fuel pipe repeatedly expands and contracts its diameter, The contracting and extending vibrations of the resin fuel pipe tilt the holding body 2. However, the expansion and contraction vibrations of the resin fuel pipe can also be effectively suppressed by the action of the vibration absorber 3. Moreover, when the resin fuel pipe is in a state of being thermally expanded by the heat released during traveling of the automobile, the holding body 2 is pushed and tilted.
Since it itself tilts around the locking leg 5 that is engaged with the mounting hole H of the panel P, the resin fuel pipe approaches the panel P side, reduces overhang from the panel P, and reduces the base body. The vibration of 1 itself can also be suppressed. In particular, when the base 1 is made of resin as in the present embodiment, the strength and rigidity of the base 1 decrease as the temperature rises, and it can be said that such advantages are extremely preferable.

Alternatively, the panel P is made of aluminum and has a rod-like body 20.
Is a steel pipe, the expansion amount of the rod-shaped body 20 becomes larger than that of the panel P as the temperature drops.
Moreover, the same advantage can be provided even in the case of operating in an environment in which the temperature is lower than that when the rod-shaped body 20 is fitted.

In the above embodiment, the axis A of the rod-shaped body 20 held by the holder 2 is locked to the base body 1 more than the sleeve-shaped axis B of the vibration absorber 3. Although it is set so as to be positioned far from the leg 5, the present invention is not limited to this. For example, as shown in A of FIG. The center A and the sleeve-shaped axis B of the vibration absorber 3 are set so as to be at the same position from the locking leg 5 of the base body 1, or conversely, as shown in B of the figure, the holder 2 It is also possible to set the axial center A of the rod-shaped body 20 held at the position closer to the locking leg 5 of the base body 1 than the sleeve-shaped axial center B of the vibration absorber 3.

According to this structure, the holding body 2 and the rod-shaped body 20 can be brought closer to the panel P side, so that the vibration and load applied to the base body 1 are reduced, the durability is improved and the clip itself is improved. Miniaturization is possible. Further, even if the resin pipe, which is a rod-shaped body, is held in a tilted state, the length of the pipe hardly changes, and even if it changes, the holding body 2 hardly tilts. Even if there are variations in the height of the sheath P, the holding positions of the pipe and the holding body 2 do not change following the variations, and from this point, stable holding can be expected.

[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 base body and the holding body with the vibration absorbing body is excellent in the vibration absorbing ability, but if the size of the vibration absorbing body itself is standardized, different types of base materials can be used. It can also be used as a holder or holder, which makes it extremely economical.

Further, in particular, under claim 1, even if the rod-shaped body is held in an inclined state, or even if the rod-shaped body is bent and tilted due to vibration, the holding body swings and follows the inclination. Therefore, there is no concern that the rod-shaped body will come off from the holding body or frictional wear, and when the holding body follows and tilts, the vibration absorber in the pressed state works to suppress the vibration of the rod-shaped body. . According to the second aspect, since the force in the direction of returning the holding body tilted from the vibration absorber to the desired assembly angle is obtained, the tilting and vibration of the holding body can be suppressed.

Further, according to the third aspect, it is possible to effectively absorb the vibration due to the swinging of the holding body and prevent the generation of the tapping sound between the base body and the holding body. According to the fourth aspect, even if the holding body is tilted due to the expansion and contraction of the rod-shaped body, the vibration absorber works to suppress the expansion and contraction vibration of the rod-shaped body. Claims 5 and 6
Since the holding body and the rod-shaped body can be held close to the fixing member side under the lower part, it is possible to effectively reduce vibrations and loads applied to the base body, improve durability, and miniaturize the clip itself.
