Description

【０００１】
【産業上の利用分野】
本発明は、相対的に移動可能な２つの部材間に介在して緩衝作用をなす緩衝部品に関する。
【０００２】
【従来の技術】
図４は従来の緩衝部品の説明図であり、緩衝部品１００はラバー単体のクッションからなり、クッション基部１０１と、このクッション基部１０１の一端に一体的に形成されたくびれ部１０２と、このくびれ部１０２の先端に一体的に形成された逆鉤部１０３とからなる。緩衝部品１００は、逆鉤部１０３を被取付部１０５の孔１０６に押圧することで、くびれ部１０２がはめ込まれる。
緩衝部品１００は、例えば図３（ａ），（ｂ）に示すように自動車のトランクリッド開放時のストッパとなるストッパ部分に取付けられて、緩衝作用をなす。
【０００３】
【発明が解決しようとする課題】
しかし、緩衝部品１００はラバー単体（一体成形品）からなるので、経年変化により孔１０６との嵌合が緩くなって、脱落する心配がある。脱落防止のために、経年変化を考慮した堅い嵌合（締め代）とすることも考えられるが、取付けに過大な押圧力が必要であり作業が容易でない。また、嵌合が堅過ぎると孔１０６への取付けが難しくなる。
本発明の目的は、被取付部への取付けが容易であり、経年変化により被取付部から脱落しない緩衝部品を提供することにある。
【０００４】
【課題を解決するための手段】
上記目的を達成するために本発明は、相対的に移動可能な２つの部材間に介在して緩衝作用をなす緩衝部品において、この緩衝部品を、尖り先形状で逆鉤部を有し被取付部の孔に着脱可能に取付けられる樹脂クリップ部材と、この樹脂クリップ部材の基部に嵌合したラバークッション部材との組合せ品で構成したことを特徴とする。
【０００５】
また、前記基部の下縁はテーパ状を呈し、前記ラバークッション部材には、組合せの際に前記樹脂クリップ部材を上から挿入するための貫通孔を開け、この貫通孔を、前記基部の挿入を容易にする上縁のテーパ部と、このテーパ部に連なり前記樹脂クリップ部材を通過させるとともに前記基部が押し広げながら通過するべく基部の外径より小径の第１孔部と、この第１孔部に連なり第１孔部より径外方へ拡開されるとともに下縁にめすテーパを有して前記基部を嵌合にて保持するための保持溝部と、この保持溝部に連なり前記基部が下へ抜けることを防止するべく前記第１孔部より小径の第２孔部とで構成する。
また、前記保持溝部は、前記基部と同一寸法又は若干小さい寸法である。
【０００６】
【作用】
緩衝部品は被取付部の孔へワンタッチ作業で取付けられる。また、クリップ部材はラバークッション部材を被取付部へ長期にわたり保持し続ける。
【０００７】
樹脂クリップ部材を貫通孔に押圧しながら挿入することで、樹脂クリップ部材をワンタッチ作業でラバークッション部材に取付けることができる。そして、基部が保持溝部に保持されることで、樹脂クリップ部材はラバークッション部材と一体化される。
第２孔部が第１孔部より小径なので、保持溝部に保持された基部が貫通孔の下から抜けることがない。このため、被取付部へ取付けられた状態の樹脂クリップ部材からラバークッション部材が脱落しない。
【０００８】
【実施例】
本発明の実施例を添付図に基づいて以下に説明する。なお、図面は符号の向きに見るものとする。
図１（ａ），（ｂ）は本発明に係る緩衝部品の断面図並びにラバークッション部材の断面図である。
緩衝部品１は、（ａ）に示すように、被取付部３の孔４（想像線にて示す貫通孔）に着脱可能に取付けられる樹脂クリップ部材１０と、この樹脂クリップ部材１０の基部１１に嵌合するラバークッション部材２０との組合せ品からなる。
【０００９】
樹脂クリップ部材１０は硬質樹脂（特に、経年変化の小さい樹脂が好ましい。）からなる一体成形品であり、円盤状の基部１１と、この基部１１から下方へ延出された垂下部１２と、この垂下部１２の下端に尖り先形状の逆鉤部１３とからなる。基部１１の下縁はテーパ状を呈する。
逆鉤部１３は相対向する一対の弾性腕１４，１４と、これら弾性腕１４，１４の自由端に有する係止突部１５，１５とからなり、これら係止突部１５，１５は互いに外向きの山形状を呈する。
【００１０】
ラバークッション部材２０はラバー（ゴム）材料からなる一体成形品であり、樹脂クリップ部材１０と組合せの際にこの樹脂クリップ部材１０を上から挿入するための貫通孔２１が略中央に開けられ、概ね円筒状を呈している。
貫通孔２１は丸孔状を呈し、上縁のテーパ部２２と、このテーパ部２２に連なり樹脂クリップ部材１０を通過させるための第１孔部２３と、この第１孔部２３に連なり第１孔部２３より径外方へ拡開され樹脂クリップ部材１０の基部１１を保持するための保持溝部２４と、この保持溝部２４に連なり第１孔部２３より小径の第２孔部２５と、一対の弾性腕１４，１４先端部が当たらないようにするための下縁の切欠き部２６とからなる。
【００１１】
テーパ部２２は第１孔部２３へ基部１１の挿入を容易にするものである。
第１孔部２３は樹脂クリップ部材１０の基部１１の外径より小径である。このため、基部１１は上から押圧されることで、第１孔部２３を押し広げながら挿入される。
保持溝部２４は基部１１と同一断面形状の丸孔状を呈し、下縁にめすテーパを有する。このため、保持溝部２４は基部１１をラバーの弾性力にて確実に保持できる。また、保持溝部２４は基部１１をラバーの弾性力にて更に確実に保持するために、保持基部１１と同一寸法又は若干小さい寸法とすることが好ましい。
第２孔部２５は第１孔部２３より小径であり、保持溝部２４に保持された基部１１が下へ抜けることを防止する。
【００１２】
ラバークッション部材２０には、下面縁部に全周にわたり薄肉のエッジ部２７が形成されており、エッジ部２７が押圧されて弾性変形することによりラバークッション部材２０は被取付部３の表面へ密着可能である（但し、この図ではエッジ部２７が弾性変形していない状態を示す。）。このため、ラバークッション部材２０は被取付部３の表面へ安定した取付け状態で保持できる。
被取付部３の孔４に逆鉤部１３が挿入された状態では、弾性腕１４，１４の拡開方向の弾性力により、被取付部３は係止突部１５，１５の上側斜面とラバークッション部材２０のエッジ部２７との間で挟持される。このため、緩衝部品１は被取付部３に堅く取付けられる。また、係止突部１５，１５の上側斜面の高さ相当分だけ被取付部３の板厚を変更可能である。
【００１３】
次に上記構成の緩衝部品１の組立手順を図２に基づき説明する。
図２（ａ），（ｂ）は本発明に係る緩衝部品の説明図である。
先ず、（ａ）に示すように、樹脂クリップ部材１０の逆鉤部１３下端をラバークッション部材２０の貫通孔２１上方に差込む。そして、樹脂クリップ部材１０を上から押圧することで、逆鉤部１３が貫通孔２１を押し広げながら通過し、次に、基部１１が第１孔部２３を押し広げながら通過して保持溝部２４に嵌合する。
従って、（ｂ）に示すように基部１１が保持溝部２４で保持されることで、樹脂クリップ部材１０とラバークッション部材２０とが組立られ、緩衝部品１を構成する。すなわち、樹脂クリップ部材１０はラバークッション部材２０にワンタッチ作業で組立られる。
【００１４】
次に緩衝部品１の取付け手順を図１に基づき説明する。
樹脂クリップ部材１０の逆鉤部１３下端を被取付部３の孔４に差込み、緩衝部品１全体を押圧する。すると、弾性腕１４，１４は孔４内を縮まりながら通過し、係止突部１５，１５が通過した時点で弾性力により拡開状態に復帰する。この時点で、被取付部３は係止突部１５，１５の上側斜面とラバークッション部材２０のエッジ部２７との間で挟持される。このため、緩衝部品１は被取付部３にワンタッチ作業で堅く取付けられる。
一方、弾性腕１４，１４を縮めながら逆鉤部１３下端を押圧すると、緩衝部品１を被取付部３の孔４から外すことができる。
【００１５】
次に緩衝部品１の使用例を図３に基づき説明する。
図３（ａ），（ｂ）は本発明に係る緩衝部品の使用例図であり、（ａ）は自動車用トランクリッドの開放状態を示す斜視図、（ｂ）はトランクリッドのヒンジ部分を示す斜視図である。
自動車３０後部のトランクルーム３１には、トランクリッド３２がヒンジ３３で開閉自在に取付けられる。トランクリッド３２開放時のストッパとなるストッパ部分（被取付部）３４の孔３５には緩衝部品１が取付けられる。
そして、緩衝部品１は、トランクリッド３２開放時にヒンジアーム３３ａと当接して緩衝作用をなす。
【００１６】
なお、上記実施例において、緩衝部品１は相対的に移動可能な２つの部材間に介在して緩衝作用をなすことを特徴とし、自動車のトランクリッド部分に取付けられる他に、例えば、自動車の各開閉部分、家庭電気品の開閉部分に取付けられる。
また、保持溝部２４は基部１１を保持することを特徴とし、保持溝部２４及び基部１１の形状は円形状の他に、例えば平面視矩形状でもよい。
【００１７】
【発明の効果】
本発明は上記構成により次の効果を発揮する。
請求項１の緩衝部品は、尖り先形状で逆鉤部を有し被取付部の孔に着脱可能に取付けられる樹脂クリップ部材と、この樹脂クリップ部材の基部に嵌合したラバークッション部材との組合せ品で構成したことにより、緩衝部品を被取付部へ取付けることが容易であり、また、クリップ部材がラバーと比較して経年変化が小さな樹脂からなるので、クリップ部材を被取付部の孔に取付けることで、緩衝部品が長期にわたり被取付部に確実に保持され、脱落の心配がない。
更に、緩衝部品が樹脂クリップ部材の基部にラバークッション部材を嵌合した構成なので、樹脂クリップ部材とラバークッション部材とを一体成形した場合に比べて成形が簡単でありコストを下げることができる。
【００１８】
さらに請求項１の緩衝部品は、基部の下縁がテーパ状を呈し、ラバークッション部材に、組合せの際に樹脂クリップ部材を上から挿入するための貫通孔を開け、この貫通孔を、基部の挿入を容易にする上縁のテーパ部と、このテーパ部に連なり樹脂クリップ部材を通過させるとともに基部が押し広げながら通過するための第１孔部と、この第１孔部に連なり第１孔部より径外方へ拡開されるとともに下縁にめすテーパを有して基部を嵌合にて保持するための保持溝部と、この保持溝部に連なり基部が下へ抜けることを防止するべく第１孔部より小径の第２孔部とで構成したことにより、樹脂クリップ部材を貫通孔に上から押圧しながら挿入するだけでラバークッション部材に簡単に取付けることができ、また、第２孔部が第１孔部より小径なので、保持溝部に保持された樹脂クリップ部材の基部が貫通孔の下から抜けることがなく、このため、被取付部へ取付けられた状態の樹脂クリップ部材からラバークッション部材が脱落する恐れがない。

[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.
FIGS. 3A and 3B are diagrams showing examples of use of the shock-absorbing component according to the present invention, in which FIG. 3A is a perspective view showing an open state of a trunk lid for an automobile, and FIG. 3B shows a hinge portion of the trunk lid. It is a perspective view.
