Description

[0001]
[Industrial application fields]
The present invention relates to a shock-absorbing component that is interposed between two relatively movable members to perform a shock-absorbing action.
[0002]
[Prior art]
FIG. 4 is an explanatory view of a conventional shock-absorbing component. The shock-absorbing component 100 is made of a single rubber cushion, a cushion base 101, a constricted portion 102 formed integrally with one end of the cushion base 101, and the constricted portion. It consists of a reverse flange 103 formed integrally with the tip of 102. In the shock-absorbing component 100, the constricted portion 102 is fitted by pressing the reverse flange portion 103 against the hole 106 of the attached portion 105.
For example, as shown in FIGS. 3A and 3B, the shock-absorbing component 100 is attached to a stopper portion that serves as a stopper when the trunk lid of the automobile is opened, and performs a shock-absorbing action.
[0003]
[Problems to be solved by the invention]
However, since the shock-absorbing component 100 is made of a single rubber (integral molded product), the fitting with the hole 106 becomes loose due to aging, and there is a concern that it will fall off. In order to prevent the dropout, it may be possible to use a tight fitting (tightening allowance) considering the secular change, but an excessive pressing force is required for the installation, and the work is not easy. If the fitting is too tight, it is difficult to attach to the hole 106.
An object of the present invention is to provide a shock-absorbing component that can be easily attached to the attached portion and does not fall off from the attached portion due to secular change.
[0004]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the present invention provides a shock-absorbing part that is interposed between two relatively movable members and has a shock-absorbing function. It is characterized by comprising a combination of a resin clip member that is detachably attached to the hole of the portion and a rubber cushion member fitted to the base portion of the resin clip member.
[0005]
Further, the lower edge of the base portion is tapered, and the rubber cushion member is provided with a through hole for inserting the resin clip member from above upon combination, and the through hole is inserted into the base portion. A taper portion at the upper edge for facilitating, a first hole portion having a diameter smaller than an outer diameter of the base portion so as to allow the resin clip member to pass through the taper portion and pass through the base portion while being expanded , and the first hole portion a holding groove for holding the base at fitting a succession taper female in expanding to Rutotomoni lower edge radially outward from the first hole, the downward said base continues into the holding groove In order to prevent detachment, the second hole portion is smaller in diameter than the first hole portion.
Further, the holding groove portion has the same size as the base portion or a slightly smaller size.
[0006]
[Action]
The shock-absorbing part is attached to the hole of the attached part by a one-touch operation. Further, the clip member continues to hold the rubber cushion member to the attached portion for a long time.
[0007]
By inserting the resin clip member while pressing the resin clip member into the through hole, the resin clip member can be attached to the rubber cushion member by a one-touch operation. And a resin clip member is integrated with a rubber cushion member because a base is hold | maintained at a holding groove part.
Since the second hole portion has a smaller diameter than the first hole portion, the base portion held in the holding groove portion does not come out from under the through hole. For this reason, the rubber cushion member does not fall off from the resin clip member attached to the attached portion.
[0008]
【Example】
Embodiments of the present invention will be described below with reference to the accompanying drawings. The drawings are viewed in the direction of the reference numerals.
1A and 1B are a cross-sectional view of a cushioning component and a cross-sectional view of a rubber cushion member according to the present invention.
As shown in (a), the shock-absorbing component 1 is attached to a resin clip member 10 detachably attached to a hole 4 (through hole indicated by an imaginary line) of the attached portion 3 and a base 11 of the resin clip member 10. It consists of a combination product with the rubber cushion member 20 to be fitted.
[0009]
The resin clip member 10 is an integrally molded product made of a hard resin (particularly a resin having a small secular change), and includes a disk-shaped base portion 11, a drooping portion 12 extending downward from the base portion 11, At the lower end of the drooping portion 12, a pointed-shaped inverted saddle portion 13 is formed. The lower edge of the base 11 is tapered.
The reverse saddle member 13 includes a pair of opposing elastic arms 14, 14 and locking projections 15, 15 at the free ends of the elastic arms 14, 14. The locking projections 15, 15 are external to each other. Presents a mountain shape in the direction.
[0010]
The rubber cushion member 20 is an integrally molded product made of a rubber (rubber) material, and when combined with the resin clip member 10, a through hole 21 for inserting the resin clip member 10 from above is opened substantially at the center. It has a cylindrical shape.
The through hole 21 has a round hole shape, a tapered portion 22 at the upper edge, a first hole portion 23 that is connected to the tapered portion 22 and allows the resin clip member 10 to pass therethrough, and a first hole portion that is connected to the first hole portion 23. A holding groove 24 for holding the base 11 of the resin clip member 10 expanded outward from the hole 23 in diameter, a second hole 25 connected to the holding groove 24 and having a smaller diameter than the first hole 23, and a pair The elastic arms 14 and 14 have a notch 26 at the lower edge to prevent the tip of the elastic arms 14 and 14 from hitting.
[0011]
The tapered portion 22 facilitates insertion of the base portion 11 into the first hole portion 23.
The first hole portion 23 has a smaller diameter than the outer diameter of the base portion 11 of the resin clip member 10. For this reason, the base 11 is inserted from the top while pushing the first hole 23 open.
The holding groove portion 24 has a round hole shape having the same cross-sectional shape as that of the base portion 11 and has a taper formed on the lower edge. For this reason, the holding groove part 24 can hold | maintain the base 11 reliably with the elastic force of a rubber. Further, it is preferable that the holding groove portion 24 has the same size as the holding base portion 11 or a slightly smaller size in order to hold the base portion 11 more securely with the elastic force of rubber.
The second hole portion 25 has a smaller diameter than the first hole portion 23 and prevents the base portion 11 held in the holding groove portion 24 from coming out downward.
[0012]
The rubber cushion member 20 is formed with a thin edge portion 27 on the entire periphery of the lower surface edge, and the rubber cushion member 20 is brought into close contact with the surface of the attached portion 3 by being elastically deformed by being pressed. It is possible (however, this figure shows a state in which the edge portion 27 is not elastically deformed). For this reason, the rubber cushion member 20 can be held in a stable attachment state on the surface of the attached portion 3.
In the state in which the reverse flange 13 is inserted into the hole 4 of the mounted portion 3, the mounted portion 3 is caused to move by the elastic force in the expanding direction of the elastic arms 14, 14 and the upper slopes of the locking projections 15, 15 and the rubber. It is clamped between the edge portions 27 of the cushion member 20. For this reason, the shock absorbing component 1 is firmly attached to the attached portion 3. Moreover, the plate | board thickness of the to-be-attached part 3 can be changed only by the height equivalent to the height of the upper side slope of the latching protrusions 15 and 15.
[0013]

Then, by pressing the resin clip member 10 from above, the reverse flange 13 passes while expanding the through hole 21, and then the base 11 passes while expanding the first hole 23 and passes through the holding groove 24. To fit.
Therefore, as shown in (b), when the base 11 is held by the holding groove 24, the resin clip member 10 and the rubber cushion member 20 are assembled to constitute the cushioning component 1. That is, the resin clip member 10 is assembled to the rubber cushion member 20 by a one-touch operation.
[0014]
Next, the attachment procedure of the buffer component 1 will be described with reference to FIG.
The lower end of the reverse flange 13 of the resin clip member 10 is inserted into the hole 4 of the attached portion 3 to press the entire cushioning component 1. Then, the elastic arms 14, 14 pass through the hole 4 while contracting, and return to the expanded state by elastic force when the locking projections 15, 15 pass. At this time, the attached portion 3 is sandwiched between the upper slope of the locking projections 15 and 15 and the edge portion 27 of the rubber cushion member 20. For this reason, the shock-absorbing component 1 is firmly attached to the attached portion 3 by a one-touch operation.
On the other hand, when the lower end of the reverse flange 13 is pressed while the elastic arms 14 and 14 are contracted, the cushioning component 1 can be removed from the hole 4 of the attached portion 3.
[0015]
Next, a usage example of the cushioning component 1 will be described with reference to FIG.
