Description

【考案の詳細な説明】 本考案は、２輪車用のスポーク車輪に関する。[Detailed explanation of the idea] The present invention relates to a spoked wheel for a two-wheeled vehicle.

従来、スポーク車輪は、第１図に示すように、スポーク

で抜止めして、リム側においてニップルで先端を締付け
ることにより構成されていた。Conventionally, as shown in FIG. 1, spoke wheels have been constructed by inserting spokes 1 into holes 2a of a bub 2, and attaching spokes to caulked portions 1a at the base ends of the spokes.
It was constructed by tightening the tip with a nipple on the rim side to prevent it from coming out.

点Ａ、Ｂにおいてスポーク１と点接触しており、使用と
共に点Ａ、Ｂが摩耗又は馴染みを呈し、スポーク１に緩
みを生じていた。By the way, when the spoke 1 is inserted from the outside as shown in a, the bending angle of the bent portion 1b widens over time and the spoke 1 becomes loose, and the spoke 1 is inserted from the inside as shown in b. In the inserted one, the hole 2a of the bub 2 was in point contact with the spoke 1 at points A and B, and with use, points A and B showed wear or familiarity, causing the spoke 1 to become loose.

このため、所定時間使用後、再度スポーク１の張りを調
節する、いわゆる増し締め作業が必要とされ、スポーク
車輪のメンテナンスを大変面倒なものにしていた。For this reason, after a predetermined period of use, it is necessary to adjust the tension of the spokes 1 again, a so-called retightening operation, which makes maintenance of the spoke wheel extremely troublesome.

そこで、本考案は、スポークを直線状に構成し、またバ

共に、組立て時の作業性を向上したスポーク車輪を提供
することを目的とするもので゛ある。Therefore, in the present invention, the spokes are configured in a straight line, and a large number of protruding lugs are provided at predetermined intervals between the bubs, and a plurality of holes are formed in these lugs that correspond to the tensioning direction of the spokes. The retaining head of the lug is bent with respect to the center line of the body on the straight line, and the head is configured to be in close contact with the seating surface of the hole of the lug, thereby solving the above-mentioned drawbacks and The object of the present invention is to provide a spoked wheel with improved workability during assembly.

以下、第２図及び第３図に沿って本考案による実施例を
説明する。Embodiments of the present invention will be described below with reference to FIGS. 2 and 3.

スポーク車輪１０はバブ１１とリム１２とを多数のスポ
ーク１３により締付け・固定して構成されている。The spoked wheel 10 is constructed by tightening and fixing a bub 11 and a rim 12 with a large number of spokes 13.

バブ１１はその左右円周上にそれぞれ互に半ピツチづら
して所定間隔毎に半径方向に突出したラグ１５・・・・
・・が多数形成されており、これらラグ１５にはそれぞ

た２個の孔１６．１６が形成されている。The bub 11 has lugs 15 that protrude in the radial direction at predetermined intervals on the left and right circumferences, respectively, and are shifted by half a pitch from each other.
... are formed in large numbers, and each of these lugs 15 has two holes 16, 16 formed therein which are slightly inclined with respect to the tangential direction of the circle formed by the bub 11.

これら２個の孔１６にはそれぞれ逆方向から直線状のス

ップル１７により締付けられている。Straight spokes 13 are inserted into these two holes 16 from opposite directions, and their tips are tightened by nipples 17 on the rim 12.

６ ａに密接するように構成されている。Further, as shown in FIG. 3, the bub-side ends of the spokes 13 are caulked to form a retaining head 13a, and the head 13a is bent with respect to the center line of the straight spoke body 13b. and the bearing surface 1 of the hole 16 of the lug 15
6 a.

なお、スポーク１３は従来のものより太めのワイヤーを
用いており、従ってその本数を減らすことか゛できる。Note that the spokes 13 are made of thicker wire than conventional ones, and therefore the number of spokes can be reduced.

以上説明したように、本考案によれば、スポーク１３の
張設方向に穿設した孔１６によりスポーク１３を取付け

を防止できる。As explained above, according to the present invention, since the spokes 13 are attached through the holes 16 drilled in the tensioning direction of the spokes 13, straight spokes 13 can be used, and the retaining head of the spokes 13 can be used. The portion 13a is the hole 16 of the lug 15.
Since the spokes are prevented from coming out by making surface contact with the seat surface 16a of the seat, the spokes do not have any bent parts or point contact parts, and the spokes are prevented from loosening due to widening of the bent part or wear of the point contact parts. It can be prevented.

従って、従来必要とされた増し締め作業を省くことがで
き、メンテナンスが容易となる。Therefore, the retightening work that was conventionally required can be omitted, and maintenance becomes easy.

また、スポーク。１３はスポーク胴部１３ｂに対し屈曲

る。Also spokes. The head 13a bent relative to the spoke body 13b comes into close contact with the hole seat surface 16a, thereby fixing the orientation, which improves workability when assembling the spoke 13. Furthermore, the spoke 13 can be assembled by rotating the nipple. When tightening the spokes 13, it is possible to prevent the spokes 13 from rotating together.
