本考案はタイヤのビード部に用いるタイヤ用ビ
ードフイラーに関するものである。[Detailed Description of the Invention] The present invention relates to a tire bead filler used in the bead portion of a tire.
従来、タイヤのビード部にビードを挿入して一
体成形する際に、ビードの上面部にデルタ状の空
間部が出来、空気が残るためタイヤの強力、耐久
性が低下するという欠点がある。 Conventionally, when a bead is inserted into the bead portion of a tire and integrally molded, a delta-shaped space is formed on the upper surface of the bead, and air remains, which has the disadvantage of reducing the strength and durability of the tire.
このため、第１図に示す如くビードワイヤ１を
複数本並列させてゴム２により被覆したビード層
３を数層重ね合わせたビード４の外周面に、上記
デルタ状の空間部に充填材として断面三角形状の
フイラー５を接着により一体に成形されている。 For this purpose, as shown in FIG. 1, a plurality of bead wires 1 are arranged in parallel and several bead layers 3 covered with rubber 2 are superimposed on the outer circumferential surface of the bead 4, and a filling material having a triangular cross section is used as a filler in the delta-shaped space. A shaped filler 5 is integrally formed by adhesion.
しかし、上記フイラー５ではビード４との接着
面が一面であるため、接着力が弱く、成形しにく
いこと、又ビード４の構成が変ればフイラー５の
形状も変えなければならないという欠点がある。 However, since the filler 5 has only one adhesive surface with the bead 4, it has a weak adhesive force and is difficult to mold, and if the configuration of the bead 4 changes, the shape of the filler 5 must also be changed.
本考案は上記欠点を除去するためになされたも
のであり、ゴム状シート材料より構成されビード
の周囲より長い全巾Ｌを有し、かつ両端にフイラ
ーを構成する略三角形状の塊状体を設け、上記塊
状体の内側の巾ｌをビードの三面の長さと略同じ
としたタイヤ用ビードフイラーを提供するもので
ある。 The present invention has been made to eliminate the above-mentioned drawbacks, and is made of a rubber-like sheet material, has a total width L longer than the periphery of the bead, and is provided with a generally triangular block forming a filler at both ends. The present invention provides a bead filler for tires in which the inner width l of the agglomerated body is approximately the same as the length of three sides of the bead.
以下本考案の一実施例を図面に基いて説明す
る。 An embodiment of the present invention will be described below with reference to the drawings.
実施例
第２図に示す如くビードフイラー６の全巾Ｌを
ビードの全周よりも長く構成し、その両端に略三
角形状の塊状体７を一体に設け、内側の巾ｌをビ
ードの三面の長さと略同じとするものである。Embodiment As shown in FIG. 2, the total width L of the bead filler 6 is configured to be longer than the entire circumference of the bead, and substantially triangular lumps 7 are integrally provided at both ends of the bead filler 6, and the inner width L is equal to the length of the three sides of the bead. It is assumed that they are almost the same.
本考案は上記の如き構成であるため、第３図イ
に示す如く円筒状に構成されたビード８の内周面
９にビードフイラー６の凹面側が内接するように
配置し、両端をビード８に包むように全周にわた
つて折り曲げることにより、第３図ロに示す如く
ビードフイラー６がビード８の全周を被覆し、略
三角形状の塊状体７が接触して、ビード８の外周
面に略三角形状のフイラー部１０が形成されるも
のである。 Since the present invention has the above-mentioned configuration, the bead filler 6 is arranged so that the concave side of the bead filler 6 is inscribed in the inner circumferential surface 9 of the bead 8 having a cylindrical shape as shown in FIG. By bending it around the entire circumference, the bead filler 6 covers the entire circumference of the bead 8 as shown in FIG. A filler portion 10 is formed.
上記フイラー部１０はロール等により圧着して
隙間のない形状のフイラーを有するビード部構造
を得ることができる。 The filler portion 10 can be pressed with a roll or the like to obtain a bead portion structure having a filler shape with no gaps.
尚、上記構成においてビードフイラーはタイヤ
のゴムとの接着性の良好なゴム物質を用いること
が好ましく、厚みは適宜選択し得るものである。 In the above configuration, it is preferable that the bead filler be made of a rubber material that has good adhesion to the rubber of the tire, and the thickness can be selected as appropriate.
本考案は上記の如き構成であるため、ビードに
対してビードフイラーが全周に接着するため、接
着力が強く、タイヤに挿入して使用した時、タイ
ヤのゴムとの密着性も良好となり、走行中ビード
がはずれたり変形したりすることがなく、安全性
の高いタイヤを得ることができる。 Since the present invention has the above-mentioned structure, the bead filler adheres to the bead around the entire circumference, so the adhesion is strong, and when used by inserting it into the tire, it has good adhesion to the tire rubber, and when running A tire with high safety can be obtained without the inner bead being dislodged or deformed.
また、塊状体の形状を略三角形状としたので、
ビードの全周を被覆して接着したとき所要の三角
形状のフイラー部を容易に得ることができ、ビー
ド部の製造工程が簡略化できる等優れた効果を有
する考案である。 In addition, since the shape of the lump is approximately triangular,
When the entire circumference of the bead is covered and bonded, the required triangular filler portion can be easily obtained, and the manufacturing process of the bead portion can be simplified.
