【考案の詳細な説明】
この考案は、回り止めを有するスポーク用ニップルに関
する。[Detailed Description of the Invention] This invention relates to a spoke nipple having a rotation stopper.
従来、スポーク用ニップルは、リムのたこ孔に挿入され
、スポークと螺合される。Conventionally, spoke nipples are inserted into holes in a rim and threaded onto spokes.
そして、リムにタイヤおよびチューブ等が組付けられ、
空気が注入されて車輪として使用されるが、使用中の衝
撃、振動および荷重等により生ずる回漕的運動により、
ニップルが回動し、スポークを緩ませる欠点があった。Then, tires, tubes, etc. are assembled on the rim,
Air is injected and used as a wheel, but due to the rotational movement caused by shock, vibration, load, etc. during use,
The disadvantage was that the nipple rotated, loosening the spoke.
この考案は、このような欠点を除去することを目的とす
るもので、以下に、その構成を図示の実施例について説
明すれば、頭部１下部の丸胴２に丸胴２の直径より大径
の回り止め３が設けられており、また、頭部１と回り止
め３との間に座金４が保持されている。The purpose of this invention is to eliminate such drawbacks, and the configuration will be explained below with reference to the illustrated embodiment. A radial detent 3 is provided, and a washer 4 is held between the head 1 and the detent 3.
上記の回り止め３は、例えば第１図および第３図に示す
ように、条痕５に構成され、丸胴２に転造板を転動圧接
することにより塑性変形を生じさせて作用される。The above-mentioned detent 3 is formed into a groove 5, as shown in FIGS. 1 and 3, for example, and is activated by causing plastic deformation by rolling and press-welding a rolled plate to the cylindrical body 2. .
従って、この転造板の転動圧接により、内部ネジ６にお
ける当該部位の有効径が縮少（Ａ＞Ｂ）されている。Therefore, due to the rolling pressure welding of the rolled plate, the effective diameter of the relevant portion of the internal screw 6 is reduced (A>B).
また、頭部１には、◇形状で凹型に圧印された締付は溝
Ｔが設けられている。Further, the head 1 is provided with a concave tightening groove T in the shape of ◇.
この締付は溝７は、頭部１の中心に開口しているネジ６
穴の谷径より大きく、且つ頭部１の外径より小さく、直
角に交差しており、さらに当り面８が軸心に対して平行
をなしている。For this tightening, the groove 7 is the screw 6 opening in the center of the head 1.
It is larger than the root diameter of the hole and smaller than the outer diameter of the head 1, intersects at right angles, and the contact surface 8 is parallel to the axis.
この考案は、このように構成されているので、第５図に
示すように、当該ニップルをリム９のたこ孔１０に挿入
し、スポーク１１と螺合するが、この場合、座金４は頭
部１と回り止め３との間に保持されているため、脱落し
、紛失する虞れはなく、また、第７図および第８図に示
すように、頭部１の締付は溝７と同形状の嵌合部１２を
有するドライバー１３を使用して自動締付けをすれば、
上記のような頭部１の締付は溝Ｔおよび当り面８の構造
作用により、ドライバー１３が締付は溝７から滑って外
れたり、浮き上ったりする虞れはなく、従って、締付は
溝７の破損がないばかりか、強い押付は力を要さずに充
分な締付はトルクを伝達することができ、作業者にとっ
て、作業性が良好で、疲労度が極めて低い。Since this device is constructed in this way, the nipple is inserted into the hole 10 of the rim 9 and screwed into the spoke 11, as shown in FIG. 1 and the detent 3, there is no risk of it falling off or being lost. Also, as shown in Figures 7 and 8, the head 1 is tightened in the same manner as the groove 7. If automatic tightening is performed using a screwdriver 13 having a shaped fitting part 12,
When tightening the head 1 as described above, due to the structural action of the groove T and the contact surface 8, there is no risk of the screwdriver 13 slipping out of the groove 7 or lifting up. Not only is there no damage to the groove 7, but strong pressing does not require force, and sufficient tightening can transmit torque, resulting in good workability and extremely low fatigue for the operator.
さらは、第６図に示すように、回り止め３の、リム９の
たこ孔１０に対する摩擦係合作用により、上記のように
締付は完了後、使用中の衝撃、振動および荷重等により
生じる回漕的運動に対して、ニップルが回動し、スポー
ク１１を緩ませる虞れはない。Furthermore, as shown in FIG. 6, due to the frictional engagement of the detent 3 with the octopus hole 10 of the rim 9, after the tightening is completed as described above, there is no damage caused by shocks, vibrations, loads, etc. during use. There is no risk of the nipples rotating and loosening the spokes 11 in response to rotational movements.
しかも、内部ネジ６において、有効径に径差（Ａ＞Ｂ）
が設けられているので、上記の締付は作業によってニッ
プルとスポーク１１が緊締され、従って、上記スポーク
１１の緩まない効果がさらに助長される。Moreover, in the internal screw 6, there is a diameter difference (A>B) in the effective diameter.
Since this is provided, the nipple and spoke 11 are tightened by the above-mentioned tightening operation, and therefore, the effect that the spoke 11 does not loosen is further promoted.
このように、この考案によれば、破損がないばかりか、
締付は作業が能率的に行なわれ得、且つ使用に耐えて緊
締状態が保持され得る、極めて有効なスポーク用ニップ
ルを提供することができる。In this way, according to this invention, not only is there no damage, but
The tightening process can be carried out efficiently, and an extremely effective spoke nipple can be provided that can be maintained in a tightened state for long periods of use.
