Description
【０００１】[0001]
本考案は、自転車等に使用するリム部、ハブ部、スポーク部を一体に成形され た樹脂ホイールに関するものである。 The present invention relates to a resin wheel integrally formed with a rim portion, a hub portion, and a spoke portion used in a bicycle or the like.
【０００２】[0002]
従来の自転車用ホイールは、リム部とハブ部を別々に製作し、この間に多数の スポークを張設して構成されていたが、製作加工部品点数が多く、また、綾取り 、個々のスポークに均等の張力を付与しなければならない等の高度の組み付け作 業の工程が要求されていたものである。 Conventional bicycle wheels were constructed by manufacturing the rim part and the hub part separately, and arranging a large number of spokes between them, but the number of processed parts was large, and the cross-cutting and the individual spokes were even. This required a high-level assembly work process, such as having to apply the tension of.
【０００３】 このような作業の簡略化を促進させるためリム部、ハブ部、スポーク部を合成 樹脂により射出成形等により一体成形した樹脂ホイールが提供された。In order to facilitate the simplification of such work, there has been provided a resin wheel in which a rim portion, a hub portion, and a spoke portion are integrally molded of a synthetic resin by injection molding or the like.
【０００４】 しかしながら、上記樹脂ホイールはスポークホイールの上記欠点を克服するこ とはできるが、ホイールの変形や破壊が起こらないように十分な剛性および強度 が必要であり、また、回転体であり大きな径を有するホイールは慣性モーメント が大きく、大きな慣性抵抗を生じる。However, although the above resin wheel can overcome the above drawbacks of the spoke wheel, it needs to have sufficient rigidity and strength so as not to cause deformation or breakage of the wheel, and it is a rotating body and has a large size. A wheel having a large diameter has a large moment of inertia, which causes a large inertial resistance.
【０００５】 特に、スポーク部、スポーク部の間に大きな曲げモーメントがかかり大きな抵 抗力が作用し、走行中路面が平滑にもかかわらず上下左右に揺れ危険な状態とな るため、樹脂ホイールにおいては、上記抵抗に耐えるために上記各部分の肉厚を 厚くしてこの抵抗に耐えるようにしなければならず、このため樹脂ホイール全体 の重量が増大するという不都合がある。In particular, since a large bending moment is applied between the spokes and a large resistance acts on the spokes, and the road surface is swaying vertically and horizontally while driving, it is dangerous to swing. However, in order to withstand the above resistance, it is necessary to increase the wall thickness of each of the above parts so as to withstand this resistance, which causes the disadvantage that the weight of the entire resin wheel increases.
【０００６】[0006]
本考案は、リム部、ハブ部、スポーク部を一体成形してなる樹脂ホイールにお いて、重量の軽減化を図り、かつ、十分な剛性および強度を備えた樹脂ホイール を提供することを課題とする。 SUMMARY OF THE INVENTION It is an object of the present invention to provide a resin wheel in which a rim portion, a hub portion and a spoke portion are integrally molded so as to reduce the weight and have sufficient rigidity and strength.
