（産業上の利用分野）
この考案は、自転車でブレーキをかける時、熱となって
放出されるエネルギーをバネなどに蓄え登り坂など大き
な力のいる時に回転エネルギーとして放出し補助する自
転車に関するものである。[Detailed description of the invention] (Field of industrial application) This invention stores the energy released as heat when applying the brakes on a bicycle in a spring, etc., and releases it as rotational energy when a large force is applied, such as when going uphill. This is related to bicycles that provide assistance.
（従来の技術）
従来より、自転車を乗るとき、下り坂ではブレーキを閉

なることがあった。(Problem to be Solved by the Invention) When riding a bicycle, when going downhill, the brakes are closed and the rotational energy is converted into thermal energy, dissipating heat and slowing down. Also, when going uphill, you had to add potential energy to the pedals in addition to the force you would use on a flat road. In other words, the descent was easy, but the ascent was difficult. Additionally, when applying the brakes, the brake pads are pinched and the friction alone stops the rotation, which can cause squeaks and the brakes to become ineffective.

本発明は以上のような構造になっていて、この動作はま
ず通常自転車を漕ぐときには、車輪（６）より伝達ギヤ
（７）が切り放されており従来と同じ動作をする。The present invention has the above-described structure, and when the bicycle is normally cycled, the transmission gear (7) is disconnected from the wheel (6), and the operation is the same as that of the conventional bicycle.
下り坂やスピードがのりスピードを落とす必要がある時
、ブレーキ操作により車輪（６）に伝達ギヤ（７）が接
続し回転を始める。When it is necessary to reduce the speed, such as when going downhill or accelerating, the transmission gear (7) is connected to the wheels (6) by applying the brake and the wheels (6) begin to rotate.
伝達ギヤ（７）が回転を始めると同時にシャフト（８）

回転しないように固定される機構になっている。The rotational energy reduced by the reduction gear (9) rotates the screw toothed shaft (13) via the clutch mechanism (10), and the gear (12) moves in a direction that compresses the spring. At this time, the gear (12) is fixed so as not to rotate by the action of the clutch.

バネ（１１）が戻らない。The gear (12) compresses the spring (11) and stores energy. This spring may be a mechanical spring or a hydraulic spring. At this time, the ratchet (17) rotates the clutch mechanism (10) in only one direction, so the spring (11) does not return.
自転車が登り坂にさしかかった時クラッチ（２１）を外
し、バネ（１１）が戻る力をギヤ（１２）に伝達し回転
エネルギーに換える。When the bicycle approaches an uphill slope, the clutch (21) is released and the returning force of the spring (11) is transmitted to the gear (12) and converted into rotational energy.

) to transfer energy. As the output gear (16) rotates, driving force is applied to the chain belt (3) to assist the pedaling force (1).
なお、伝達ギヤ（７）の代わりにダイナモ等の発電機に

い。Note that a generator such as a dynamo may be used instead of the transmission gear (7), and a storage battery and a motor may be used instead of the spring (11).
（発明の効果）
登り坂で自転車を漕ぐとき下り坂などで貯えられたエネ
ルギーを使うので非常に楽に登れる。(Effects of the invention) When riding a bicycle uphill, you use the energy stored when riding downhill, so you can climb up very easily.

、製造原価も安く製造工程も簡単である。In addition, when energy is stored, the rotation of the wheels slows down, just like applying brakes on a car's engine, so it can be used in conjunction with conventional brakes, and there is less weight on the brake pads, which reduces the chance of squeaky brakes becoming ineffective. . Furthermore, since the structure is simple, the manufacturing cost is low and the manufacturing process is simple.
