〔産業上の利用分計〕
本発明は、自動車の窓枠に装着し、窓ガラスの端縁と接
するガラスランに関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application] The present invention relates to a glass run that is attached to a window frame of an automobile and comes into contact with the edge of the window glass.
ガラスランは一般に、第３図に示すように窓枠（図示路
）に沿って保持され、内面が窓ガヲス４の端面と接する
基底部１と、基底部１０両端から基底部ユとほぼ直角に
かつ互に平行に伸びる側面部２と、両側面部の先端から
内側に伸び窓ガラス４の周縁部同面と接触するリップ部
３とよシなる。Generally, the glass run is held along the window frame (the path shown in the figure) as shown in FIG. It consists of side parts 2 that extend parallel to each other, and lip parts 3 that extend inward from the tips of both side parts and come into contact with the same surface of the peripheral edge of the window glass 4.
最近では塩化ビニル製のものが多用されており、押出成
形によシ製造される。These days, vinyl chloride products are often used, and they are manufactured by extrusion molding.
ところで、ガラスランのリップ部５の先端部および基底

キサン等の滑剤を混入せしめる手段がとられていた（特
開昭り４−４３５８４０号）。By the way, the tip of the lip part 5 of the glass run and the inner surface of the base part 1 are required to be slippery because they come into sliding contact with the window glass 4 when the glass is raised and lowered. They were applying paint. In addition, measures have been taken to mix lubricants such as silicone oil, fluororesin, and polydimethylsiloxane into vinyl chloride (Japanese Unexamined Patent Publication No. 4-435840).
しかしながら、ガラスとの摺接部、特に基底部１ではガ
ラス昇降時にスティックスリップが生じ、ガラスの角部
がくい込んだりして摺動抵抗が局部的に大きくなり、従
ってガラスランの耐摩耗性も充分でなかった。However, stick-slip occurs at the sliding contact parts with the glass, especially the base part 1, when the glass is raised and lowered, and the corners of the glass get wedged, resulting in locally large sliding resistance.Therefore, the wear resistance of the glass run is insufficient. It wasn't.
〔本発明が解決しようとする問題点〕
そこで本発明は、スティックスリップがなく、摺動性が
良好であって耐久性にすぐれたガラスランを提供し、も
って従来の問題点を解決することを目的とするものであ
る。[Problems to be Solved by the Present Invention] Therefore, the present invention aims to solve the conventional problems by providing a glass run that is free from stick-slip, has good sliding properties, and has excellent durability. This is the purpose.
発明者らは上記従来の問題点を解決するためにガラスラ
ンの硬度に着目した。即ち、ガラスランのリップ部３に
″は撓み性が要求されることから、従来はガラスラン全
体を硬度（Ｊ工５Ａ）６０〜８０度程度と皮表いた。In order to solve the above conventional problems, the inventors focused on the hardness of the glass run. That is, since the lip portion 3 of the glass run is required to have flexibility, conventionally the entire glass run has been given a hardness (J-5A) of about 60 to 80 degrees.
しかしながら、かかる硬度では窓ガラス昇降時のガタッ
キやガラス傾斜角の変化によって基底部にガラスがくい
込み、スティックスリップが生じる。従って、植毛をし
ても、あるいは基材に滑剤を配合しても、充分な滑性と
耐久性が得られない。However, with such hardness, stick-slip occurs when the glass gets wedged in the base due to rattling when the window glass is raised or lowered or changes in the glass inclination angle. Therefore, even if hair is flocked or a lubricant is added to the base material, sufficient lubricity and durability cannot be obtained.

ましい。本発明のガラスランは硬さの異る塩化ビニルを
一体押出成形することＫより得られる。In the present invention, the glass run is constructed of vinyl chloride containing a lubricant, and as shown in the figure, the base portion 1 is constructed of vinyl chloride, which is harder than other parts. In addition, as shown in Fig. 1112, the base part 1 is made of vinyl chloride v which does not contain a lubricant and has a higher hardness than other parts, and the inner surface of this hard part is coated with a vinyl chloride coating layer 12 containing a lubricant. Form. The hardness of the hard part should be about 95 degrees or more than J Engineering SA. The glass run of the present invention is obtained by integrally extruding vinyl chloride having different hardness.
基底部の硬さを大きくしたことで、スティックスリップ

久性も向上する。また、本発明のガラスランは一体押出
成形により得られ、植毛や塗装の必要がない。By increasing the hardness of the base, stick-slip is prevented, sufficient lubricity is obtained, and the durability of the glass run is also improved. Further, the glass run of the present invention is obtained by integral extrusion molding, and there is no need for flocking or painting.

てシリコーンオイルが混入せしめである。The glass run shown in FIG. 1 consists of a base part 1, a side part 2 and a lip part 3. The glass run is made of vinyl chloride, and the central part of the base part 1 in contact with the end surface of the window glass 2 is a hard part 1 with a hardness of 85 degrees or more, and the other parts are hard parts 1 with a hardness of 85 degrees or more.
It is between 0 and 80 degrees. Silicone oil is mixed throughout the glass run as a lubricant.

これ等を一体押出成形することにより得られる。This glass run is made by adding silicone oil to each of two types of vinyl chloride/I/VC with adjusted amounts of plasticizer.
It is obtained by integrally extruding these materials.

ニルを一体押出成形することにより得られる。In the glass run shown in FIG. 2, the hard part 11 has a hardness of 1c8F) or more as in the above embodiment, but does not contain a lubricant. The side surface portion 2 and the lip 163K contain a lubricant. On the inner surface of the hard part 11, a coating 12 of vinyl chloride containing a lubricant of the same kind as the side part 2 and the lip part 3 is formed. This glass run is obtained by integrally extruding two types of vinyl chloride.

持される。According to the present invention, since the base portion 11 is made hard, the window can be easily formed either when the base portion 11 itself forms a slippery surface (FIG. 1) or when a slippery coating 12 is formed (FIG. 2). Even if the strength of the contact with the base part 11 changes when the glass is raised or lowered, it slides smoothly without getting wedged, no slips occur, and the glass run has excellent durability. On the other hand, the lip portion 3 maintains the necessary flexibility.
