Abstract

PROBLEM TO BE SOLVED: To provide a flat-belt bicycle training device which provides a sense of handle operation similar to a real cycling.SOLUTION: On frames 301, 302, a rear rear-wheel roller 101 and a front rear-wheel roller 102 arranged in parallel are provided with an interval therebetween in accordance with an outer shape of a rear wheel B2 of a bicycle B. The front rear-wheel roller 102 and a front-end roller 103 are provided with a longer interval by a wheel base of the bicycle B, allowing a belt transmission by a flat belt 5. When a bicycle B is operated, a rotational force is transmitted from the rear wheel B2 to the rear rear-wheel roller 101 and the front rear-wheel roller 102. This rotational force allows an upper surface of the flat belt 5 to move from a front side to a rear side of a cyclist 1 via the front-end roller 103, allowing a self-standing operation.SELECTED DRAWING: Figure 1

Description

本発明は、自転車の後輪の前後に配置した回転自在なローラー上で、前輪タイヤが真上に接地する位置に前ローラーを配置する、乗員のペダル踏力を後輪ローラーからベルトなどで伝達して前ローラーを回転させ、これにより前輪を回転し自転車を自立走行可能にして、自転車の位置を固定して練習をすることができるようにした自転車走行練習装置に関する。 In the present invention, a front roller is disposed at a position where a front tire contacts a ground directly on a rotatable roller disposed on the front and rear of a rear wheel of a bicycle. The present invention relates to a bicycle running practice device that rotates a front roller and thereby rotates a front wheel so that the bicycle can run independently and can practice by fixing the position of the bicycle.

実公開平２−７７０６０号公報の図１及び図３に示すように、従来の自転車走行練習装置は、後２本・前１本のローラーにより構成され、ペダルを回動することにより、後輪の２本のローラーを回転させると共に、ベルトの伝動により前輪ローラーを従動させて、その場で自転車の自立走行練習ができるような装置、以降は３本ローラーと記すが実用化されている。 As shown in FIG. 1 and FIG. 3 of Japanese Utility Model Publication No. 2-77060, the conventional bicycle practice device is composed of two rear rollers and one front roller. The two rollers are rotated and the front wheel roller is driven by the transmission of the belt so that the bicycle can be practiced on its own, and the following three rollers are put into practical use.

特公昭５０−７１４２５号公報Japanese Patent Publication No. 50-71425

この様な３本ローラーにおいては前輪が１本のローラーに接地して回転して、ハンドル操作によりローラー上を左右に移動可能することにより、乗員がバランスを保ち、自転車の自立走行練習が可能にしているが次の問題が有った。In such a three-roller, the front wheel touches and rotates on one roller and can be moved to the left and right by operating the steering wheel, so that the occupant can maintain balance and practice running independently on the bicycle. However, there was the following problem.

前記３本ローラーでは前輪が前部ローラー上に有り、接地面が円弧上の一点となる。しかし、通常の路面は平面であるそのため、路上とは前輪タイヤの接地圧と復元力が異なり、実際に平坦な路面を走行する時とはハンドル操作の感覚が異なる In the three rollers, the front wheel is on the front roller, and the ground contact surface is a point on the arc. However, because the normal road surface is a flat surface, the ground pressure and restoring force of the front wheel tires are different from those on the road, and the feeling of steering wheel operation is different from when actually driving on a flat road surface.

前記３本ローラーでは前輪中心軸がローラーに対して直上に乗るように位置を調整しなければならないが、高い回転数でペダルを踏む自立走行練習を行うと、乗員の体重移動により前後に自転車が動きローラーに接地している部分も前後移動する、これにより前輪の回転軸と接地点が移動するとハンドルを回転させる力が加わり、ハンドルが取られ自立走行する事が困難になる、最悪の場合では自転車がローラーから外れ前か後に落ちる。The position of the three-roller must be adjusted so that the center axis of the front wheel rides directly above the roller. The part that is in contact with the moving roller also moves back and forth, which adds a force to rotate the handle when the rotating shaft of the front wheel and the contact point move, making it difficult for the handle to be taken and running independently, in the worst case The bicycle falls before or after it comes off the roller.

上り坂で大きなペダル踏力を得るためにサドルに座らずに立ち漕ぎ（ダンシング）を、前記３本ローラーで行うと、自転車を左右に振ってペダルを踏むと、ハンドルを切ることにより前輪のローラーに接地している部分と後輪の接地部の距離が短くなる、これによりハンドルを回転させる力が加わり、バランスをとり自立走行する事が困難になる。In order to obtain a large pedaling force on the uphill, if you stand up (dancing) without sitting on the saddle with the above three rollers, swing the bike to the left or right and step on the pedal. The distance between the grounded part and the grounded part of the rear wheel is shortened, which adds a force to rotate the handle, making it difficult to balance and run independently.

本発明の自転車走行練習装置は、上記課題を達成するため、ローラー保持フレームに平行に配置した、後輪用ローラーと前端のローラーとを平ベルトで回転自在に連動させ、ベルトの上面の平面部に前車輪配置して、平坦な路面を走行する時と同じタイヤの復元力を得る物である。In order to achieve the above object, the bicycle running practice device of the present invention is arranged in parallel with the roller holding frame, and the roller for the rear wheel and the roller at the front end are rotatably linked by a flat belt, and a flat portion on the upper surface of the belt The front wheels are arranged at the front to obtain the same tire restoring force as when traveling on a flat road surface.

前記機構により、後輪に連動して走行速度と同じ速さで移動するベルトの上面を平坦な路面を走行する時と同じな前輪のタイヤの復元力、同じジャイロ効果を得て安定した自転車走行練習が可能である。By the above mechanism, the bicycle can move stably at the same speed as the running speed in conjunction with the rear wheels, and the same front wheel tire restoring force and the same gyro effect as when running on a flat road surface. Practice is possible.

自転車を左右に振ってペダルを踏む立ち漕ぎ（ダンシング）の自立走行練習でも、ハンドルを左右に切る走行でも接地点は平面であり前輪回転軸とずれる事はなく実際の路面と同じハンドル操作で自立走行練習が出来る。Swing your bike to the left and right and step on the pedal. Even when you practice running independently (dancing), or when you run the steering wheel to the left or right, the grounding point is flat and does not deviate from the front wheel rotation axis. Practice running.

本考案の実施例を図面を参照しながら具体的に説明すると。
図１は本考案の使用状態で、床面にフレーム右３０１・フレーム左３０２が接地される、このフレームと床面の接地部は高さを調整可能な調整式ゴム足３１０などを使用してゴムなどの弾性体で振動を防ぐ。An embodiment of the present invention will be specifically described with reference to the drawings.
FIG. 1 shows a state in which the present invention is used. The frame right 301 and the frame left 302 are grounded on the floor surface. The grounding portion of the frame and the floor surface uses an adjustable rubber foot 310 whose height can be adjusted. Vibration is prevented with an elastic body such as rubber.

図面には表記していないが、上り坂の状態を模した自立走行練習には調整式ゴム足３１０を高さ変更可能なアクチェーターに換え、平ベルト５の抵抗と上り坂の勾配を制御して、実際の上り坂に近い状態で踏む立ち漕ぎ（ダンシング）の自立走行練習が可能になる。Although not shown in the drawing, for independent running practice simulating an uphill condition, the adjustable rubber feet 310 are replaced with an actuator that can change the height, and the resistance of the flat belt 5 and the slope of the uphill are controlled. This makes it possible to practice standing up (dancing) on a stand-alone basis while walking near an actual uphill.

フレーム３０１・３０２には平行に配置した後輪ローラー後１０１及び後輪ローラー前１０２を自転車Ｂの後輪Ｂ２の外形に合わせた間隔で配置する、後輪ローラー前１０２と前端ローラー１０３は自転車Ｂのホイールベースにより長い間隔で配置して平ベルト５でベルト伝動可能にする。The rear wheel roller rear 101 and the rear wheel roller front 102 arranged in parallel with the frames 301 and 302 are arranged at intervals corresponding to the outer shape of the rear wheel B2 of the bicycle B. The rear wheel roller front 102 and the front end roller 103 are arranged on the bicycle B. The wheel base is arranged at longer intervals so that the belt can be driven by the flat belt 5.

乗員１は自転車Ｂに乗車して、走行すると後輪Ｂ２より後輪ローラー後１０１及び後輪ローラー前１０２に回転力が伝わる、この回転力が平ベルト５を前端ローラー１０３を介して上面が乗員１の前方から後方に移動させる。When the occupant 1 rides on the bicycle B and travels, the rotational force is transmitted from the rear wheel B2 to the rear wheel roller rear 101 and the rear wheel roller front 102. This rotational force causes the flat belt 5 to pass through the front end roller 103 and the upper surface is occupant. Move from the front of 1 to the back.

平ベルト５の移動により接地する前車輪Ｂ１の回転は後輪Ｂ２と同じに回転するので、前車輪Ｂ１のジャイロ効果は乗員１が通常の路面を走行するのと同じになり、同じ位置で通常の走行と同じ操作感で自立走行練習が可能になる。Since the rotation of the front wheel B1 that contacts the ground due to the movement of the flat belt 5 rotates in the same manner as the rear wheel B2, the gyro effect of the front wheel B1 is the same as when the occupant 1 travels on a normal road surface, and normally at the same position. Independent driving practice is possible with the same feeling of operation as driving.

補助ローラー１０４は平ベルト５に前車輪Ｂ１が接地する部分の荷重により沈み込みを防ぐ物で、図では４本で有るが、使用する自転車のホイールベースに応じ前車輪Ｂ１が接地する部分に適切に配置する。The auxiliary roller 104 prevents the sinking by the load of the portion where the front wheel B1 contacts the flat belt 5, and it is four in the figure, but is suitable for the portion where the front wheel B1 contacts the ground according to the wheelbase of the bicycle used. To place.

補助ローラー１０４から後輪ローラー前１０２までの間には足付き板右２１１・足付き板左２１２を平ベルト５の下に配置して、自転車Ｂに乗車、降車するときに足付き時に平ベルト５の下への沈み込みを無くし乗降時の違和感を無くす。Between the auxiliary roller 104 and the front wheel roller 102, the right foot plate 211 and the left foot plate 212 are disposed under the flat belt 5 so that the flat belt can be used when riding on and off the bicycle B. Eliminate the sinking below 5 and eliminate the feeling of strangeness when getting on and off.

平ベルト５の張りは前端ローラー１０３の軸をアジャスター４０１により後輪ローラー前１０２との距離を調整して行う。The flat belt 5 is tensioned by adjusting the distance between the front roller 103 and the front roller 102 by an adjuster 401.

図面には表記していないが、本実施形態に負荷機構は前端ローラー１０３に装備される、負荷を大きくすると前端ローラー１０３の回転が重くなり、これに対応して乗員１はペダルを強く踏み込み後輪Ｂ２とそれに連動する、後輪ローラー前１０２の回転を維持するので、負荷が大きくなれば応じて平ベルト５の上面の張力が上るので、補助ローラー１０４への平ベルト５の前車輪Ｂ１の荷重による圧力が減少し、走行面がより平滑になる。Although not shown in the drawings, the load mechanism is installed in the front end roller 103 in this embodiment. When the load is increased, the rotation of the front end roller 103 becomes heavier, and the occupant 1 strongly depresses the pedal accordingly. Since the rotation of the wheel B2 and the rear wheel roller front 102 linked to the wheel B2 is maintained, the tension on the upper surface of the flat belt 5 increases as the load increases, so the front wheel B1 of the flat belt 5 to the auxiliary roller 104 The pressure due to the load decreases and the running surface becomes smoother.
