Description

本発明は、自動車用のドアに取付けられるガラスランに関する。   The present invention relates to a glass run attached to an automobile door.

ガラスランは、図1に示す自動車を例にとっていえば、フロントドア1とリヤドア2のドア周りのサッシュ又はフレームにドアガラス3の昇降を案内するために設けられ、通常、ゴム又は熱可塑性エラストマーの成形品で、押出成形部と、コーナ部に取付けられる型成形部よりなっている。図2は、図1のA−A線断面でのサッシュ4に装着されるガラスランの押出成形部5の断面構造を示すもので、底壁6と、該底壁6の両端に一体形成される車内側及び車外側の側壁7及び8と、各側壁7及び8の端部に一体形成されて底壁6に向かって延出し、ドアガラス9を閉じたとき、ドアガラス9に両側より弾接してシールすると共に、ドアガラスを支持する車内側及び車外側のシールリップ11及び12と、車内側側壁7より車内側に折り返され、車内側側壁7と断面略U形状をなして、サッシュ4に形成されるガラスラン嵌合部14の車内側側縁より内周側に向けて突出するフランジ15に差込まれ、該フランジ15を覆うカバーリップ16と、車外側側壁8端に一体形成され、車外側に突出してガラスラン嵌合部14の車外側側縁に弾接するカバーリップ17とよりなっている。図中18はサブリップで、走行時のガラスの振動により発生するラトル音(ガラス振動音)を抑えるために設けられている。   Taking the automobile shown in FIG. 1 as an example, the glass run is provided to guide the raising and lowering of the door glass 3 to the sash or frame around the doors of the front door 1 and the rear door 2, and is usually made of rubber or thermoplastic elastomer. The molded product consists of an extrusion molding part and a mold molding part attached to a corner part. FIG. 2 shows a cross-sectional structure of the extruded portion 5 of the glass run attached to the sash 4 in the cross section taken along the line AA of FIG. 1, and is formed integrally with the bottom wall 6 and both ends of the bottom wall 6. The inner and outer side walls 7 and 8 and the end portions of the side walls 7 and 8 are integrally formed and extend toward the bottom wall 6. When the door glass 9 is closed, the door glass 9 is elasticated from both sides. The inside and outside sealing lips 11 and 12 that support the door glass, and the inside side wall 7 are folded back to the inside of the vehicle to form a sash 4 having a substantially U-shaped cross section. The glass run fitting portion 14 is formed in a flange 15 protruding toward the inner peripheral side from the vehicle inner side edge, and is integrally formed with the cover lip 16 covering the flange 15 and the end of the vehicle outer side wall 8. The outer side of the glass run fitting 14 protrudes outward from the vehicle. It is becoming more and elastically contact cover lip 17. In the figure, reference numeral 18 denotes a sub lip which is provided to suppress rattle noise (glass vibration noise) generated by glass vibration during travel.

こうしたガラスランでは、押出成形時にシールリップ11、12が互いに接触することのないように、また型成形部では中子の抜き取りに支障を来たすことがないように、両側壁7、8を開口側が開いた展開状態で成形し、前記ガラスラン嵌合部14に装着して取付けるときには、両側壁7、8の開口側を窄めた状態で押し込み、拡開する復元力でガラスラン嵌合部14に密着して保持させるようにしている。なお、型成形部は、図示していないが、前述の押出成形部5と同様、底壁と、該底壁の両端に一体形成される車内側及び車外側の側壁と、各側壁の端部に一体形成されるシールリップを備えている。   In such a glass run, the side walls 7 and 8 are arranged on the opening side so that the seal lips 11 and 12 do not come into contact with each other at the time of extrusion molding, and so as not to hinder the extraction of the core in the molding part. When the glass run fitting portion 14 is molded in an open unfolded state and mounted and attached to the glass run fitting portion 14, the glass run fitting portion 14 is pushed in with the opening side of the side walls 7, 8 being narrowed and expanded. It is made to hold in close contact with. In addition, although the mold forming part is not shown in the drawing, like the above-described extrusion molding part 5, the bottom wall, the vehicle inner and outer side walls integrally formed at both ends of the bottom wall, and the end of each side wall And a seal lip formed integrally with each other.

前述する従来のガラスランでは、ドアのサッシュ又はフレームのコーナに取付けるに際し、型成形部を窄めると、型成形部が均一に変形せず、このためガラスラン全体がドアのサッシュ又はフレームに追従しなくなり、取付不良を起すことがある。この問題を解決するため、底壁部にV形の伸縮部を形成し、成形時には伸縮部を幅方向の車内外方向に伸ばしてシールリップが互いに接触することがないようにし、またサッシュ又はフレームへの取付時には両側壁部を内向きに平行移動させて伸縮部を縮めた状態でガラスラン嵌合部に装着するグラスランが提案されている(特許文献1)。   In the conventional glass run described above, when the mold forming part is narrowed when the door is attached to the door sash or the corner of the frame, the mold forming part is not uniformly deformed. Therefore, the entire glass run is not attached to the door sash or frame. It may not follow and may cause mounting failure. In order to solve this problem, a V-shaped expansion / contraction part is formed on the bottom wall part, and at the time of molding, the expansion / contraction part is extended in the vehicle interior / exterior direction so that the seal lips do not come into contact with each other. There has been proposed a glass run that is attached to a glass run fitting portion in a state in which both side wall portions are translated inward at the time of attachment to the telescopic portion and the expansion / contraction portion is contracted (Patent Document 1).

ガラスランのシールリップは、ドアガラスに弾接し、ドアガラスとの間をシールする機能を有するほか、ドアガラスを両側より挟持して支持する機能を有するが、ドアガラスが走行中に振動してラトル音と称される振動音を発生させることがある。この問題に対処するガラスランとして、ドアサッシュに装着されるガラスランを断面略コ字形の金属製チャンネル部と、ドアガラスの端部を差込んで挟持する断面略Ω形の保持部と、該保持部とチャンネル部の両側壁と底壁とを連結する腕部を備えたガラスランも提案されている(特許文献2)。   The seal lip of the glass run has the function of elastically contacting the door glass and sealing between the door glass, and also has the function of sandwiching and supporting the door glass from both sides, but the door glass vibrates during traveling. Oscillating noise called rattle noise may be generated. As a glass run to cope with this problem, a metal channel portion having a substantially U-shaped cross section for a glass run mounted on a door sash, a holding portion having a substantially Ω-shaped cross section for inserting and sandwiching an end portion of the door glass, There has also been proposed a glass run including arm portions that connect both the side walls and the bottom wall of the holding portion and the channel portion (Patent Document 2).

図3に示すガラスラン21は、前述のガラスラン1と同様、サッシュ4に形成されるガラスラン嵌合部14に装着されるもので、一対の脚部22aを略山形に連結して断面略逆V形溝を構成する保持部22と、該保持部22を構成する両脚部22aの脚部端よりそれぞれ保持部22両外側に折り返される車内側の係止壁部22b及び車外側の係止壁部22cと、保持部22の頂部近くよりガラスラン嵌合部14に突出して横向きに折曲げられる係止リップ22dよりなり、両係止壁部22b及び22cにはそれぞれ先端側に両外側に突出し、ガラスラン嵌合部14の両側壁の被係止部に係着する係止部22e、22fを一体形成し、硬質樹脂のバネ体で構成され、全体が断面略W形をなすガラスラン本体23と、車内側の係止壁部22bより車内側に向けて一体に突出形成される略U形断面のカバーリップ24と、車外側の係止壁部22cより車外側に向けて一体に突出形成される断面略レ形のカバーリップ25よりなり、これらカバーリップ24及び25は、いずれもゴム様弾性体であるEPDM等のゴム又は熱可塑性エラストマーにより形成されている。   The glass run 21 shown in FIG. 3 is attached to the glass run fitting portion 14 formed on the sash 4 in the same manner as the glass run 1 described above. A holding portion 22 forming an inverted V-shaped groove, a locking wall portion 22b on the vehicle inner side and a locking on the vehicle outer side that are folded back from the leg ends of both leg portions 22a forming the holding portion 22 to both outer sides of the holding portion 22, respectively. It consists of a wall portion 22c and a locking lip 22d that protrudes from the vicinity of the top of the holding portion 22 into the glass run fitting portion 14 and bends sideways. A glass run that protrudes and is integrally formed with locking portions 22e and 22f that are engaged with locked portions on both side walls of the glass run fitting portion 14 and is composed of a hard body of a hard resin, and has a substantially W-shaped cross section as a whole. From the main body 23 and the locking wall portion 22b inside the vehicle A cover lip 24 having a substantially U-shaped cross-section formed integrally and projecting toward the inside, and a cover lip 25 having a generally cross-shaped cross-section formed integrally and projecting from the engagement wall portion 22c on the vehicle exterior toward the vehicle exterior. These cover lips 24 and 25 are both made of rubber such as EPDM, which is a rubber-like elastic body, or a thermoplastic elastomer.

自動車用ドアのサッシュに形成されるガラスラン嵌合部14は凹溝状で、ガラスラン嵌合部14を構成する車内側及び車外側の側壁部はいずれも形状を多少異にするが、段27a、27bを備えた被係止部となっている。   The glass run fitting portion 14 formed on the sash of the automobile door has a concave groove shape, and the side walls on the vehicle inner side and the vehicle outer side constituting the glass run fitting portion 14 are slightly different in shape. It becomes a to-be-latched part provided with 27a, 27b.

ガラスラン21をサッシュのガラスラン嵌合部14に装着するときには、両係止壁部22b及び22cを内向きに両側より押込んでガラスラン本体23の車内外方向の幅を窄め、ガラスラン嵌合部14に押込む。この押込みは係止部22e、22fがガラスラン嵌合部14の車内側及び車外側の側壁部の段27a、27bに係止して抜け止めされるまで行われ、抜け止めされた状態で車内側の係止壁部22b及び車外側の係止壁部22cがガラスラン嵌合部14の両側壁部の被係止部に係着し、かつ係止リップ22dがガラスラン嵌合部14底に当り、保持部22を図3の上下方向に弾力的に支持する。   When the glass run 21 is attached to the glass run fitting portion 14 of the sash, both the locking wall portions 22b and 22c are pushed inward from both sides to narrow the width of the glass run main body 23 in the vehicle interior / exterior direction. Push into joint 14. This pushing operation is performed until the locking portions 22e and 22f are locked to the steps 27a and 27b on the inner side and the outer side wall portions of the glass run fitting portion 14 and are prevented from being detached. The inner locking wall portion 22b and the outer locking wall portion 22c are engaged with the locked portions on both side walls of the glass run fitting portion 14, and the locking lip 22d is the bottom of the glass run fitting portion 14. In this case, the holding portion 22 is elastically supported in the vertical direction in FIG.

ガラスラン21の前述する押込みによってまた、カバーリップ24が前記フランジ15に差込まれると共に、カバーリップ25がガラスラン嵌合部14の車外側縁部に弾接し、嵌合部14の両側縁を覆って外観を向上させると共に、ガラスラン21の保持機能を果たし、ガラスラン21の保持を安定化させる。   As the glass run 21 is pushed in as described above, the cover lip 24 is inserted into the flange 15 and the cover lip 25 elastically contacts the outer edge of the glass run fitting portion 14 so that both side edges of the fitting portion 14 are formed. Covering and improving the appearance, fulfills the function of holding the glass run 21, and stabilizes the holding of the glass run 21.

前記実施形態のガラスラン21はポリエチレン、ポリプロピレン、硬度90A以上の熱可塑性エラストマー等の硬質樹脂で形成されているが、鋼等の金属製であってもよく、また樹脂と金属の二層構造をなしていてもよい。いずれにしても略逆V形溝を構成する保持部内面のうち、少なくともドアガラスを閉じたとき、ドアガラス端部と接触する部分は、ドアガラス端部が当たっても衝突音を発生させず、またドアガラスの開閉がスムースに行えるように摺動抵抗の小さな材質で形成するか、或いは摺動抵抗の小さな樹脂をコーティングしておくのが望ましい。   The glass run 21 of the above embodiment is formed of a hard resin such as polyethylene, polypropylene, and a thermoplastic elastomer having a hardness of 90A or more, but may be made of metal such as steel, and has a two-layer structure of resin and metal. It may be done. In any case, of the inner surface of the holding portion constituting the substantially inverted V-shaped groove, at least when the door glass is closed, the portion that contacts the door glass edge does not generate a collision sound even if the door glass edge hits. In addition, it is desirable that the door glass is formed of a material having a low sliding resistance so that the door glass can be opened and closed smoothly, or is coated with a resin having a low sliding resistance.

前記実施形態のガラスラン21はまた、カバーリップ24及び25を有しているが、別の実施形態のガラスランではカバーリップ24及び25が省かれ、ガラスラン本体23のみで構成される。   The glass run 21 of the above embodiment also has cover lips 24 and 25. However, in the glass run of another embodiment, the cover lips 24 and 25 are omitted and only the glass run main body 23 is configured.

図4に示すガラスラン31は、図3に示すグラスラン21において、カバーリップ24及び25の内側(ガラス側)の側面24Iと25Iより内向きに、保持部22内に向けて延出するシールリップ32及び33を一体形成し、該シールリップ32及び33がドアガラス9に両面より弾接してドアガラス9を支持すると共に、シールするようになっている。   The glass run 31 shown in FIG. 4 is a seal lip that extends inward from the side surfaces 24I and 25I on the inside (glass side) of the cover lips 24 and 25 in the glass run 21 shown in FIG. 32 and 33 are integrally formed, and the seal lips 32 and 33 elastically contact the door glass 9 from both sides to support and seal the door glass 9.

図5に示すガラスラン36は、図2に示すグラスラン21において、車外側のシールリップ33を保持部22の頂部とは逆向きの図の下方に向けて延出した外側シールリップ37としたもので、ドアガラス9を閉じて走行するときに風がドアガラス9とシールリップ37との間に巻き込まれて生ずる風切音を図4に示すものよりも低減させることができるようにしている。   The glass run 36 shown in FIG. 5 is a glass run 21 shown in FIG. 2 in which the outer side seal lip 33 is extended toward the lower side of the figure opposite to the top of the holding portion 22. Thus, wind noise generated when the door glass 9 is closed and the wind is caught between the door glass 9 and the seal lip 37 can be reduced more than that shown in FIG.

図6に示すガラスラン41は、図4に示すグラスラン31において、車外側のカバーリップ25にシールリップ33と共に、図5に示す外側シールリップ37を一体形成したもので、本実施形態のガラスラン41も図5に示すガラスラン36と同様の効果を生じ、風切音を低減させることができる。   A glass run 41 shown in FIG. 6 is obtained by integrally forming an outer seal lip 37 shown in FIG. 5 together with a seal lip 33 on the cover lip 25 on the outside of the glass run 31 shown in FIG. 41 also produces the same effect as the glass run 36 shown in FIG. 5, and can reduce wind noise.

前記実施形態では、図1のA−A線断面であるフロントドアのセンターピラー側のガラスランを示したが、ピラー側だけでなく、例えば図1においてBで示す箇所、つまりルーフ側に取付けられるガラスランを前記ガラスランと同様に構成してもよい。 In the above embodiment, the glass run on the center pillar side of the front door, which is a cross section taken along the line AA in FIG. 1, is shown, but it is attached not only to the pillar side, but also to the location indicated by B in FIG. You may comprise a glass run similarly to the said glass run.
