Description

【0001】
【発明の属する技術分野】
本発明は、自動車のドアサッシュに取り付けられ、ドアガラスを上昇させて閉じた際に発生するいわゆる底付き音の低減化を図ったグラスランに関するものである。
【0002】
【従来の技術】
図1乃至図4を参照して説明する。従来、自動車のドアサッシュ1に取り付けられるグラスラン30において、ドアガラス3を上昇させて閉じた際に発生する底付き音の発生を防止するために種々の工夫がなされてきた。
【0003】
一般的には、図2に示すように、グラスラン本体31の基部32に、ドアサッシュ1に弾接する外側リップ部33を一体設したり、図3に示すように、グラスラン本体31の基部32にドアガラス3の先端面に弾接する内側リップ部34を設けている。これらは、共に、その全体をソリッドゴム材Sで形成している。
【0004】
また、図4に示すように、ソリッドゴム材Sで形成したグラスラン本体31の基部32に、ドアガラス3の先端面に弾接する比重が0.4〜0.6である通常のスポンジゴム材Nで構成した緩衝片35を設けたものもある。
【0005】
【発明が解決しようとする課題】
これら従来のグラスランは、底付き音の発生をある程度抑えることができるものの、未だ充分とは言えず、改良の余地が残されている。
【0006】
本発明は係る問題に鑑み創案されたもので、ドアガラスを上昇させて閉じた際に発生する底付き音を、大幅に低減することのできるグラスランを提供することを課題とする。
【0007】
【課題を解決するための手段】
図1,図5及び図6を参照して説明する。第一の発明は、自動車のドアサッシュ1に取り付けられ、ドアガラス3先端部が基部12を挟んでドアサッシュ1に衝突するグラスランであって、ソリッドゴム材S製のグラスラン本体11と比重が0.15〜0.4の低密度スポンジゴム材L製のブロック片20との共押出一体成形により,グラスラン本体11の基部12外面に、ドアサッシュ1の底部2に弾接するブロック片20を設けると共に基部12の内面にドアガラス3に弾接する内側リップ部17を設け、前記ドアガラス3を上昇させて閉じた際に、当該ドアガラス3の先端部が基部12を挟んで前記ドアサッシュ1に衝突し、前記基部12とドアサッシュ1との間に設けた前記ブロック片20及び内側リップ部17が、衝突の際の衝撃を和らげると共に衝撃音を吸収し、底付き音を低減することを特徴とするものである。
【0008】
第二の発明は、自動車のドアサッシュ1に取り付けられ、ドアガラス3先端部が基部12を挟んでドアサッシュ1に衝突するグラスランであって、ソリッドゴム材S製のグラスラン本体11と比重が0.15〜0.4の低密度スポンジゴム材L製のブロック片20との共押出一体成形により,グラスラン本体11の基部12外面に形成した凹部13に、ドアサッシュ1の底部2に弾接する、ブロック片20を設けると共に基部12の内面にドアガラス3に弾接する内側リップ部17を設け、前記ドアガラス3を上昇させて閉じた際に、当該ドアガラス3の先端部が内側リップ部17及び基部12を挟んで前記ドアサッシュ1に衝突し、前記基部12とドアサッシュ1との間に設けた前記ブロック片20及び内側リップ部17が、衝突の際の衝撃を和らげると共に衝撃音を吸収し、底付き音を低減することを特徴とするものである。
【0009】
【発明の実施の形態】
第一の発明の実施形態を、図1および図5に示す。このグラスラン10は、自動車のドアサッシュ1に取り付けられるもので、基部12、側部14、アウターシールリップ部15およびインナーシールリップ部16で構成されるグラスラン本体11をソリッドゴム材Sで形成している。そして、基部12の外面に、ドアサッシュ1の底部2に弾接するブロック片20を、共押出し成形によって一体的に設けている。このブロック片20は、比重が0.15〜0.4程度である低密度スポンジゴム材Lで形成している。
【0010】
グラスラン本体11とブロック片20を共押出成形しているので、製造コスト上有利である。
【0011】
又、低密度スポンジゴム材の比重が0.15未満では、特にグラスラン本体11と共押出一体成形する場合、安定して製造する事が困難となるので好ましくない。又、比重が0.4を越えると、底付き音低減効果が少なくなるので好ましくない。
【0012】
又、本発明の実施形態例では、サッシュドアタイプ車のドアサッシュの例のみを図示し、説明したが、パネルドアタイプ車のドアパネルにリテーナーを一体化したものの場合でも、同様に適用が可能である。
【0013】
低密度スポンジゴム材の比重は、0.15〜0.4が好ましいが、底付き音低減効果と、安定して製造する事の両方を考慮すると、0.2〜0.3がより好ましい。
【0014】
このグラスラン10を使用すると、ドアガラス3を上昇させて閉じた際に、当該ドアガラス3先端部が内側リップ部及び基部12を挟んでドアサッシュ1に衝突するが、基部12とドアサッシュ1との間に低密度スポンジゴム材L(比重0.15〜0.4)で形成したブロック片20及び内側リップ部17を設けているので、当該ブロック片20及び内側リップ部17が衝突の際の衝撃を和らげると共に、衝撃音を吸収するので底付き音を大幅に低減することができる。
【0015】
なお、このブロック片20が底付き音の大幅な削減を図り得る理由は、それを低密度スポンジゴム材Lで形成していることによる。低密度スポンジゴム材Lに代えて通常のスポンジゴム材N(比重0.4〜0.6)を使用することもできるが、その場合、底付き音を大幅に低減することはできない。
【0016】
また、低密度スポンジゴム材Lに代えて、比重が0.05〜0.14の高発泡連続気泡スポンジ材(例えば、日東電工株式会社製、商品名:エプトシーラー)を使用することも考えられる。しかし、高発泡連続気泡スポンジ材は、低密度スポンジゴム材Lと比較してさらに比重が小さく、圧縮永久歪みが大きい。従って、当初は低密度スポンジゴム材Lと同等に底付き音の低減を効果的に図ることができるものの、時間の経過と共に永久変形を起こし、その性能が急激に低下する。そのため、高発泡連続気泡スポンジ材を低密度スポンジゴム材Lに代えて使用することも適当でない。
【0017】
低密度スポンジゴム材Lを底付き音を低減するために使用するといった技術思想は、これまで存在しない。それは、グラスラン本体11を比重が1.0〜1.2のソリッドゴム材Sで形成するため、比重が0.15〜0.4であり、ソリッドゴム材Sとは比重差の大きい低密度スポンジゴム材Lを、共押し出し成形等によって一体的に設けることが技術的に困難であるため、そうすることは技術的な常識から逸脱してしまうと考えられてきたからである。本発明者はこうした従来の固定概念を払拭し、ここに、これまでに存在しない新規な発明を創作するに至ったものである。
【0018】
また、基部12の内面に設けた内側リップ部17により、底付き音のさらなる低減を図っている。
【0019】
第二の発明の実施形態を、図6に示す。このグラスラン10は、ソリッドゴム材Sで形成したグラスラン本体11の基部12外面に凹部13を形成し、その凹部13に、ドアサッシュ1の底部2に弾接する比重が0.15〜0.4である低密度スポンジゴム材Lで形成したブロック片20を設けたことを特徴としている。
【0020】
ブロック片20を凹部13に設けたことによって、ブロック片20の基部12に対する組付き姿勢をより安定したものとすることができるので、底付き音の低減を長期にわたって確実に図ることができるといった効果を発揮する。
【0021】
【実施例】
本発明者らは、低密度スポンジゴム材Lと通常スポンジゴム材Nを使用して、それぞれがどの程度衝撃音(底付き音)を低減できるかについて実験を行った。この実験は、ブロック片20と同程度の肉厚(2mm)に設定した低密度スポンジゴム材Lと通常スポンジゴム材Nのそれぞれを、グラスラン本体11の基部12と同程度の肉厚(2mm)に設定したソリッドゴム材Sに貼り付けたシート材を鉄製の金属台に載せ、その上に、直径35mm、重さ約198gの鉄球を、100mmの高さから落下し、50mmの高さで、且つ50mm離れた位置に設置したマイクでその衝撃音を測定した。その結果を、図のグラフに示す。
【0022】
この実験から明らかなように、低密度スポンジゴム材Lを使用したシート材の方が、通常スポンジゴム材Nを使用したシート材より、衝撃音を大幅に低減することが分かる。従って、ブロック片20を低密度スポンジゴム材Lで形成した本発明に係るグラスラン10は、ブロック片20を通常スポンジゴム材Nで形成したものと比較して、底付き音の発生を大幅に低減できることが明らかとなった。
【0023】
【発明の効果】
第一の発明に係るグラスラン10は、ソリッドゴム材Sで形成したグラスラン本体11の基部12の内面にドアガラス3に弾接する内側リップ部17を設けると共に基部12外面に、ドアサッシュ1の底部2に弾接する比重が0.15〜0.4である低密度スポンジゴム材Lで形成したブロック片20を設けたので、ドアガラス3を上昇させて閉じた際に発生する底付き音を大幅に低減することができる。
【0024】
第二の発明に係るグラスラン10は、ソリッドゴム材Sで形成したグラスラン本体11の基部12の内面にドアガラス3に弾接する内側リップ部17を設けると共に基部12外面に凹部13を形成し、その凹部13に、ドアサッシュ1の底部2に弾接する比重が0.15〜0.4である低密度スポンジゴム材Lで形成したブロック片20を設けたので、ブロック片20の基部12に対する組付き姿勢をより安定したものとすることができる。これにより、底付き音の低減を長期にわたって確実に図ることができる。

[0009]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the first invention is shown in FIGS. The glass run 10 is attached to a door sash 1 of an automobile. A glass run body 11 including a base portion 12, a side portion 14, an outer seal lip portion 15 and an inner seal lip portion 16 is formed of a solid rubber material S. Yes. And the block piece 20 which elastically contacts the bottom part 2 of the door sash 1 is integrally provided in the outer surface of the base 12 by coextrusion molding. The block piece 20 is formed of a low density sponge rubber material L having a specific gravity of about 0.15 to 0.4.
[0010]
Since the glass run body 11 and the block piece 20 are co-extruded, it is advantageous in terms of manufacturing cost.
[0011]
In addition, when the specific gravity of the low density sponge rubber material is less than 0.15, it is not preferable because it is difficult to stably produce the glass run body 11 and the glass run body 11 in a co-extrusion integral molding. On the other hand, if the specific gravity exceeds 0.4, the effect of reducing the bottomed sound is reduced, which is not preferable.
[0012]
Further, in the embodiment of the present invention, only the example of the door sash of the sash door type vehicle is illustrated and described, but the present invention can be similarly applied even when the retainer is integrated with the door panel of the panel door type vehicle. .
[0013]
The specific gravity of the low density sponge rubber material is preferably 0.15 to 0.4, but more preferably 0.2 to 0.3 in consideration of both the bottoming sound reduction effect and stable production.
[0014]
When this glass run 10 is used, when the door glass 3 is raised and closed, the front end portion of the door glass 3 collides with the door sash 1 with the inner lip portion and the base portion 12 interposed therebetween. Since the block piece 20 and the inner lip portion 17 formed of the low density sponge rubber material L (specific gravity 0.15 to 0.4) are provided between the block piece 20 and the inner lip portion 17 during the collision. While reducing the impact and absorbing the impact sound, the bottomed sound can be greatly reduced.
[0015]
The reason why the block piece 20 can greatly reduce the bottoming sound is that it is formed of the low density sponge rubber material L. A normal sponge rubber material N (specific gravity 0.4 to 0.6) can be used instead of the low density sponge rubber material L, but in that case, the bottomed sound cannot be significantly reduced.
[0016]
Further, instead of the low density sponge rubber material L, it is also conceivable to use a highly foamed open cell sponge material having a specific gravity of 0.05 to 0.14 (for example, trade name: EPT SEALER, manufactured by Nitto Denko Corporation). However, the high foamed open cell sponge material has a smaller specific gravity and a larger compression set than the low density sponge rubber material L. Therefore, although it is possible to reduce the bottoming sound as effectively as the low-density sponge rubber material L at the beginning, permanent deformation occurs with the passage of time, and the performance is drastically lowered. Therefore, it is not appropriate to use the high foamed open cell sponge material in place of the low density sponge rubber material L.
[0017]
There has never been a technical idea that the low-density sponge rubber material L is used for reducing the bottom sound. This is because the glass run body 11 is formed of a solid rubber material S having a specific gravity of 1.0 to 1.2, so that the specific gravity is 0.15 to 0.4, and a low density sponge having a large specific gravity difference from the solid rubber material S. This is because it is technically difficult to provide the rubber material L integrally by coextrusion molding or the like, and it has been considered that doing so would deviate from technical common sense. The present inventor has wiped out such a conventional fixed concept, and has now created a novel invention that does not exist so far.
[0018]
Further, the inner lip portion 17 provided on the inner surface of the base portion 12 further reduces the bottomed sound.
[0019]
An embodiment of the second invention is shown in FIG. The glass run 10 has a concave portion 13 formed on the outer surface of the base 12 of the glass run body 11 made of a solid rubber material S, and the specific gravity of the concave portion 13 elastically contacting the bottom portion 2 of the door sash 1 is 0.15 to 0.4. A block piece 20 made of a certain low density sponge rubber material L is provided.
[0020]
By providing the block piece 20 in the recess 13, the assembly posture of the block piece 20 with respect to the base portion 12 can be made more stable, so that the effect of reducing the bottoming sound can be reliably achieved over a long period of time. Demonstrate.
[0021]
【Example】
The present inventors conducted experiments on how much each can reduce the impact sound (bottom sound) using the low density sponge rubber material L and the normal sponge rubber material N. In this experiment, each of the low-density sponge rubber material L and the normal sponge rubber material N set to the same thickness (2 mm) as the block piece 20 has the same thickness (2 mm) as the base 12 of the glass run body 11. The sheet material affixed to the solid rubber material S set on is placed on an iron metal base, and an iron ball having a diameter of 35 mm and a weight of about 198 g is dropped from a height of 100 mm on the metal plate, and at a height of 50 mm. The impact sound was measured with a microphone installed at a position 50 mm away. The results are shown in the graph of FIG.
[0022]
As is clear from this experiment, it is understood that the sheet material using the low-density sponge rubber material L significantly reduces the impact sound compared to the sheet material using the normal sponge rubber material N. Therefore, the glass run 10 according to the present invention in which the block piece 20 is formed of the low-density sponge rubber material L significantly reduces the occurrence of bottom sound compared with the block run 20 formed of the normal sponge rubber material N. It became clear that we could do it.
[0023]
【The invention's effect】
The glass run 10 according to the first invention is provided with an inner lip portion 17 that elastically contacts the door glass 3 on the inner surface of the base portion 12 of the glass run body 11 formed of the solid rubber material S, and the bottom portion 2 of the door sash 1 on the outer surface of the base portion 12. Since the block piece 20 formed of a low density sponge rubber material L having a specific gravity of 0.15 to 0.4 elastically contacting with the door glass 3 is raised, the bottoming sound generated when the door glass 3 is raised and closed is greatly reduced. Can be reduced.
[0024]
The glass run 10 according to the second invention is provided with an inner lip portion 17 that elastically contacts the door glass 3 on the inner surface of the base portion 12 of the glass run body 11 formed of the solid rubber material S, and a concave portion 13 is formed on the outer surface of the base portion 12. Since the block piece 20 formed of the low density sponge rubber material L having a specific gravity of 0.15 to 0.4 elastically contacting the bottom portion 2 of the door sash 1 is provided in the concave portion 13, the block piece 20 is assembled to the base portion 12. The posture can be made more stable. As a result, the bottomed sound can be reliably reduced over a long period of time.
