特開平７−２５７４７２号公報JP-A-7-257472

本発明は、上述の問題に鑑みてなされたものであり、その目的はチェーンレス自転車およびチェーンあり自転車の両方に適用可能な固定装置を提供することにある。   The present invention has been made in view of the above-described problems, and an object thereof is to provide a fixing device applicable to both a chainless bicycle and a bicycle with a chain.

上述の目的を達成するために、自転車のハブ内に位置する変速器を固定するのに用いられる固定装置は、固定軸、取外し棒、および調整ナットを備える。固定軸は、ハブの回転軸として自転車の変速器を固定するのに用いられ、軸方向を貫通する貫通孔を有し、外表面に少なくとも一つの軸方向に伸びている補強部が形成している。取外し棒の後側の末端に調整ナットがねじ付けられていることで、自転車のフレームに固定軸が固定されている。

図１は本発明の第一実施形態による固定装置をチェーンレス自転車に適用したものを示す。図３は本発明の第二実施形態による固定装置をチェーンあり自転車に適用したものを示す。図１と図３の中の変速器の構造は同じであり、外部動力を伝達する方法だけが異なる。本発明の固定装置は二種類の自転車に適用することができる。   FIG. 1 shows a fixing device according to a first embodiment of the present invention applied to a chainless bicycle. FIG. 3 shows a fixing device according to a second embodiment of the present invention applied to a bicycle with a chain. The structure of the transmission in FIGS. 1 and 3 is the same, and only the method for transmitting external power is different. The fixing device of the present invention can be applied to two types of bicycles.

図１と図２はチェーンレス自転車の変速器に適用する第一実施形態を示す。図３と図４はチェーンあり自転車の変速器に適用する第二実施形態を示す。この二つの実施形態とも変速器１の両末端が固定ナット１０により固定軸２に固定されており、固定軸２の両末端の雄ねじ２０の間に位置する。図１と図３とが示すように、ハブ６の両側（変速器１の両側）は左側蓋３と右側蓋４とに連結されており、ベアリングにより固定軸２に組み付けられている。ハブ６の内部には変速器１が収容されている。ハブ６は固定軸２を中心として自由に回転することができる。   1 and 2 show a first embodiment applied to a chainless bicycle transmission. 3 and 4 show a second embodiment applied to a bicycle transmission with a chain. In both of these embodiments, both ends of the transmission 1 are fixed to the fixed shaft 2 by the fixing nut 10, and are positioned between the male screws 20 at both ends of the fixed shaft 2. As shown in FIGS. 1 and 3, both sides of the hub 6 (both sides of the transmission 1) are connected to the left lid 3 and the right lid 4, and are assembled to the fixed shaft 2 by bearings. The transmission 1 is accommodated in the hub 6. The hub 6 can freely rotate about the fixed shaft 2.

図５〜図８は、変速器１の実施形態を示す。変速器１はチェーンレス自転車とチェーンあり自転車に適用可能である。固定軸２の両末端に雄ねじ２０を設け内部変速器１の固定ナット１０とねじ合うことで、変速器１が固定軸２に固定されて組み付けられる。固定軸２の外表面と雄ねじ２０との間には少なくとも一本以上の補強溝２１が形成されている。変速器の部品（直径方向に動力を伝達する部品、変速切り換え用のはじき棒）が嵌まり込まれている。図１３と図１４は応用例を示す。固定軸２の軸方向に中心部を貫通する貫通孔２２が形成されており、取外し棒７が貫通して設置されている。然し取外し棒７は固定軸２の貫通孔２２を貫通する前に先に両側を自転車のフレーム８を貫通させてから取外し棒７の後側の末端が調整ナット７１とねじ付けられる。それで固定軸２をフレーム８に固定して組み付ける。反対に固定軸２をフレーム８からはずしたい時は、ただ調整ナット７１を緩めて外せば、取外し棒７を固定軸２の貫通孔２２から引き出して、固定軸２を簡単にフレーム８からはずすことができる。   5 to 8 show an embodiment of the transmission 1. The transmission 1 can be applied to a chainless bicycle and a bicycle with a chain. The male screw 20 is provided at both ends of the fixed shaft 2 and screwed with the fixing nut 10 of the internal transmission 1, whereby the transmission 1 is fixed to the fixed shaft 2 and assembled. At least one reinforcing groove 21 is formed between the outer surface of the fixed shaft 2 and the male screw 20. The parts of the transmission (parts for transmitting power in the diametrical direction, repelling bars for changing gears) are fitted. 13 and 14 show application examples. A through hole 22 penetrating the center portion is formed in the axial direction of the fixed shaft 2, and the removal rod 7 is installed therethrough. However, before the removal rod 7 passes through the through hole 22 of the fixed shaft 2, the bicycle frame 8 is first penetrated on both sides, and then the rear end of the removal rod 7 is screwed to the adjustment nut 71. Thus, the fixed shaft 2 is fixed to the frame 8 and assembled. On the other hand, when it is desired to remove the fixed shaft 2 from the frame 8, simply loosen and remove the adjustment nut 71, and the removal rod 7 can be pulled out from the through hole 22 of the fixed shaft 2, and the fixed shaft 2 can be easily removed from the frame 8. Can do.

次に図９〜図１２は、変速器１の固定軸２の別の実施形態を示す。固定軸２は広くチェーンレスの自転車とチェーンありの自転車に適用できる、固定軸２の両末端はある長さの雄ねじ２０を設けて、内部変速器１の固定ナット１０とねじ合って、変速器１が固定軸２に固定して組み付けられる。固定軸２は両末端の雄ねじ２０の間の外表面に少なくとも一本以上の凸状補強リブ２３が設けられて、固定軸２を補強する。凸状補強リブ２３の相互間の隙間２３１は変速器１の部品（例へばギヤ９１）の組み付けに利用される。図１５と図１６はその応用例である。固定軸２の軸方向の中心部に貫通する貫通孔２２が形成されている。取外し棒７が先に自転車のフレーム８を貫通してから固定軸２の貫通孔２２を貫通して、別のフレーム８を貫通してからその後側の末端を調整ナット７１で締め付けることで簡単に固定軸２がフレーム８に固定されて組み付けられる。   Next, FIGS. 9 to 12 show another embodiment of the fixed shaft 2 of the transmission 1. The fixed shaft 2 can be widely applied to a chainless bicycle and a chain-equipped bicycle. Both ends of the fixed shaft 2 are provided with male screws 20 having a certain length, and are screwed with the fixed nut 10 of the internal transmission 1 to thereby transmit the transmission. 1 is fixed to the fixed shaft 2 and assembled. The fixed shaft 2 is provided with at least one or more convex reinforcing ribs 23 on the outer surface between the male screws 20 at both ends to reinforce the fixed shaft 2. The gap 231 between the convex reinforcing ribs 23 is used for assembling parts of the transmission 1 (for example, the gear 91). 15 and 16 are application examples. A through hole 22 penetrating through the axial center of the fixed shaft 2 is formed. The removal rod 7 passes through the bicycle frame 8 first, then passes through the through hole 22 of the fixed shaft 2, passes through another frame 8, and then tightens the rear end with an adjusting nut 71. The fixed shaft 2 is fixed to the frame 8 and assembled.

本発明による固定装置はチェーンレス自転車とチェーンあり自転車に適用できるので実用性が広い。又固定軸をフレームに組み付けたり、はずしたりする時は、取外し棒７を操作するだけで、組み合せや取はずしが迅速で、製造作業が迅速になり、コストが安くなり、産業上の利益が高くなり、空間を有効に利用可能なので、全体の重量が軽減される。   Since the fixing device according to the present invention can be applied to a chainless bicycle and a bicycle with a chain, it has wide utility. Also, when attaching or removing the fixed shaft to / from the frame, simply operating the removal rod 7, the assembly and removal is quick, the manufacturing work is quick, the cost is low, and the industrial benefits are high. Thus, the space can be used effectively, and the overall weight is reduced.
