Description

本考案は、チェーンベルト式自転車のベルト締着度調整構造に関するもので、ギア盤のチェーンベルトに連動するフリーホイール回転軸ユニットを、偏心塊を具えた一定位補助管内に設置し、定位補助管を車体フレーム軸管に設置すると、偏心塊箇所を軸管内で異なる角度位置に調整することによって、チェーンベルトのチェーンベルト締着度を調整する。   The present invention relates to a structure for adjusting the belt tightening degree of a chain belt type bicycle. A freewheel rotating shaft unit interlocking with a chain belt of a gear board is installed in a fixed auxiliary pipe having an eccentric lump, and a fixed auxiliary pipe. Is installed on the body frame shaft tube, the degree of tightening of the chain belt of the chain belt is adjusted by adjusting the eccentric lump location to different angular positions in the shaft tube.

公知のチェーンベルト式自転車構造は、おおよそ図一、二に示すとおりで、一車体フレーム１の軸管２内にフリーホイール３の回転軸４を設置して駆動する(注：フリーホイール３は、正回転では回転軸４の連動によってギア盤６を連動し、逆回転では回転軸４を空転させてギア盤６を連動しない構造である)。回転軸４はギア盤６、クランク５を連結し、ギア盤６は更にチェーンベルト７、後輪１２を連結する。チェーンベルト７をずっと使用していると緩んでくるので、その時にはチェーンベルト締着度を調整しなければならない。その調整方式は、後輪１２のネジ栓１１を緩め、後輪１２を後へ引いて(図二参照)チェーンベルト７を締める。言い換えれば、その軸管２箇所のフリーホイール３の回転軸４、ギア盤６は位置を調整できない。
特開平２００３−１９１８８５号公報 A known chain belt type bicycle structure is roughly as shown in FIGS. 1 and 2 and is driven by installing a rotating shaft 4 of a freewheel 3 in a shaft tube 2 of a vehicle body frame 1 (Note: the freewheel 3 is In the forward rotation, the gear panel 6 is interlocked by interlocking with the rotation shaft 4, and in the reverse rotation, the rotation shaft 4 is idled so that the gear panel 6 is not interlocked. The rotating shaft 4 connects a gear board 6 and a crank 5, and the gear board 6 further connects a chain belt 7 and a rear wheel 12. If the chain belt 7 is used for a long time, it will come loose, and at that time the chain belt fastening degree must be adjusted. In the adjustment method, the screw plug 11 of the rear wheel 12 is loosened, the rear wheel 12 is pulled rearward (see FIG. 2), and the chain belt 7 is tightened. In other words, the positions of the rotary shaft 4 and the gear board 6 of the free wheel 3 at the two axial tubes cannot be adjusted.
JP-A-2003-191885

解決しようとする問題点は、先ず、自行車のブレーキライジング片１４は車体フレーム１に固定し、且つブレーキライジング片１４は後輪１２のリム１３に正確に対応する必要があり、それによってブレーキをかけた時に、ライジング片がリム１３に接触する。また公知では後輪１２の位置を調整する必要があるため、ブレーキライジング片１４がリム１３に不正確に対応すると影響を与える。
次に後輪１２は、車体フレーム1にしっかりと固定し、正確に締めなければならない。チェーンベルト締着度を調整するには後輪１２を動かさなければならず、そのためには専業者に調整を依頼しなければならず、素人が調整することができない点である。 The problem to be solved is that the brake rising piece 14 of the own vehicle must first be fixed to the vehicle body frame 1 and the brake rising piece 14 must accurately correspond to the rim 13 of the rear wheel 12, thereby applying the brake. When rising, the rising piece contacts the rim 13. Further, since it is necessary to adjust the position of the rear wheel 12 in the known art, it is affected if the brake rising piece 14 corresponds to the rim 13 inaccurately.
Next, the rear wheel 12 must be firmly fixed to the body frame 1 and tightened accurately. In order to adjust the chain belt tightening degree, the rear wheel 12 must be moved, and for that purpose, adjustments must be requested from a specialist, and the amateur cannot make adjustments.

本考案は、チェーンベルトの締着度を調整するのに、実用効果を具える。本考案は主に定位補助管に設置して駆動するフリーホイール回転軸を設置し、定位補助管を車体フレームの軸管に設置し、軸助定位管の外周には偏心塊を設置する。定位補助管の偏心塊箇所を軸管内の異なる角度位置に調整することによって、その回転軸の位置を調整し、つまりは回転軸が連結するギア盤位置を調整し、更にギア盤に噛み合っているチェーンベルトのチェーンベルト締着度を調整するため、後輪位置を調整する必要がないことを最も主要な特徴とする。   The present invention has a practical effect for adjusting the fastening degree of the chain belt. The present invention mainly installs a freewheel rotating shaft that is installed and driven on a localization auxiliary pipe, installs the localization auxiliary pipe on the axis pipe of the vehicle body frame, and installs an eccentric mass on the outer periphery of the axis auxiliary localization pipe. The position of the rotating shaft is adjusted by adjusting the eccentric mass location of the localization auxiliary tube to a different angular position in the shaft tube, that is, the position of the gear board to which the rotating shaft is connected is adjusted and further meshed with the gear board. The main feature is that it is not necessary to adjust the position of the rear wheel in order to adjust the chain belt fastening degree of the chain belt.

本考案のチェーンベルト式自転車のベルト締着度調整構造は、後輪を調整することなく、簡単、スピーディにチェーンベルトの締着度を調整するという利点がある。   The belt fastening degree adjusting structure of the chain belt type bicycle of the present invention has an advantage that the fastening degree of the chain belt is easily and quickly adjusted without adjusting the rear wheel.

図三、四、五、六に示すとおり、車体フレーム２０にはネジ孔を具えた軸管２１を設置する。フリーホイール３３、回転軸３６を設置したフリーホイール外筐３４一端には外ネジ歯３５を設置し、またフリーホイール３３の回転軸３６を一定位補助管３０に設置する。その定位補助管３０は両端に内ネジ歯３１を具え、フリーホイール外筐３４と螺合し、更に一外ネジ歯のナット３でフリーホイール外筐３４を固定する。定位補助管３０外周には偏心塊３２を設置し、定位補助管３０を車体フレーム２０の軸管２１内に組み入れ、ネジ栓２３を軸管２１のネジ孔２２に差し込み、偏心塊３２を押さえて定位補助管３０を定位させる。 As shown in FIGS. 3, 4, 5 and 6, the body frame 20 is provided with a shaft tube 21 having a screw hole. An external screw tooth 35 is installed at one end of the free wheel outer casing 34 on which the free wheel 33 and the rotation shaft 36 are installed, and the rotation shaft 36 of the free wheel 33 is installed on the fixed auxiliary pipe 30. The localization auxiliary tube 30 has inner screw teeth 31 at both ends, and is screwed with a freewheel outer casing 34, and the freewheel outer casing 34 is fixed with a nut 3 having one outer screw tooth. An eccentric lump 32 is installed on the outer periphery of the localization auxiliary tube 30, the localization auxiliary tube 30 is incorporated into the shaft tube 21 of the vehicle body frame 20, a screw plug 23 is inserted into the screw hole 22 of the shaft tube 21, and the eccentric lump 32 is pressed. The localization auxiliary tube 30 is localized.

組立は、図三、四に示すとおり、先ずフリーホイール３３の回転軸３６及びそのフリーホイール外筐３４を定位補助管３０内に螺合設置し、別一端はナット３７で定位補助管３０に固定してフリーホイール外筐３４が緩むのを防止する。次に定位補助管３０全体を車体フレーム２０の軸管２１内に組み入れ、ネジ栓２３で定位補助管３０の偏心塊３２を押さえて固定する。フリーホイール３３の回転軸３６は方形で、それをギア盤６の方形中心孔、及びクランク５に嵌合することによって、脚でクランク５を回転させた時、フリーホイール３３の回転軸３６を回転させ、そしてギア盤６がチェーンベルト７(図六参照)を回転させる。 As shown in FIGS. 3 and 4, first, the rotating shaft 36 of the free wheel 33 and the free wheel outer casing 34 are screwed and installed in the localization auxiliary pipe 30, and the other end is fixed to the localization auxiliary pipe 30 by a nut 37. Thus, the freewheel outer casing 34 is prevented from loosening. Next, the entire localization auxiliary tube 30 is incorporated into the shaft tube 21 of the vehicle body frame 20, and the eccentric mass 32 of the localization auxiliary tube 30 is pressed and fixed by the screw plug 23. The rotation shaft 36 of the free wheel 33 is square, and when the crank 5 is rotated by the legs by fitting it into the square center hole of the gear board 6 and the crank 5, the rotation shaft 36 of the free wheel 33 is rotated. The gear board 6 rotates the chain belt 7 (see FIG. 6).

チェーンベルト７のチェーンベルト締着度を調整する時、図五、六に示すとおり、先ずネジ栓２３を緩め、次に工具を定位補助管３０の偏心塊３２側辺の回転孔３２０に差し込み(図三参照)、偏心塊３２を回転させて定位補助管３０を必要な角度に回転させる。言い換えると、偏心塊３２の箇所を車体フレーム２０の軸管２１内で異なる角度位置にすると、回転軸３６の位置が変わり、回転軸３６が前へ動いた時、ギア盤６が前へ動き、チェーンベルト７が締まる。 When adjusting the chain belt tightening degree of the chain belt 7, as shown in FIGS. 5 and 6, first, the screw cap 23 is loosened, and then the tool is inserted into the rotation hole 320 on the side of the eccentric lump 32 of the localization auxiliary pipe 30 ( The eccentric lump 32 is rotated to rotate the localization auxiliary tube 30 to a required angle. In other words, when the location of the eccentric mass 32 is set to a different angular position in the shaft tube 21 of the body frame 20, the position of the rotary shaft 36 changes, and when the rotary shaft 36 moves forward, the gear board 6 moves forward. The chain belt 7 is tightened.

上述の説明からもわかるとおり、本考案でチェーンベルト７チェーンベルト締着度を調整する時、ただ定位補助管３０の偏心塊３２を回転させればよく、後輪１２と車体フレーム２０の固定を外す必要がないので、作業が非常に簡単で、スピーディに調整を行え、且つ後輪ブレーキライジング片１４とリム１３の対応正確度に影響しない。 As can be seen from the above description, when adjusting the degree of tightening of the chain belt 7 and the chain belt in the present invention, it is only necessary to rotate the eccentric mass 32 of the localization auxiliary tube 30 and fix the rear wheel 12 and the body frame 20. Since it is not necessary to remove, the work is very simple, speedy adjustment can be performed, and the corresponding accuracy of the rear wheel brake rising piece 14 and the rim 13 is not affected.
