(57) [Summary] (Corrected) [Purpose] Instead of braking the bicycle with the hand grip of the handbrake, the brake is applied with the foot using the pedal reverse rotation method. [Composition] In order to brake with a foot, a freewheel is provided on a crankshaft, a caliber brake is connected with a brake lot, and a bicycle and a rear wheel rim are pressed by the caliber brake for braking.

Description

【考案の詳細な説明】[Detailed description of the device] 【産業上の利用分野】[Industrial applications]

本考案は自転車の制動装置に関する。 The present invention relates to a bicycle braking device.

【従来の技術】[Prior art]

従来の自転車のブレーキは全てハンドブレーキによる手の握力で働く制動装 置のものであった。 All conventional bicycle brakes are braking devices that work with the hand grip of the handbrake.

【考案が解決しようとする課題】[Problems to be solved by the device]

前記の如き(ブレーキ)装置では、手の不自由な者などは、自転車に乗るこ とが許されず、又片手に物を持つなどして自転車に乗った時には、急停車ができ ず甚だ危険である欠点がある。本考案は上記の如き欠点をなくす目的から考案し たものである。 With the above-mentioned (brake) device, people with handicap are not allowed to ride a bicycle, and when riding a bicycle with an object in one hand, it is not possible to stop suddenly, which is very dangerous. There are drawbacks. The present invention is designed to eliminate the above drawbacks.

【課題が解決するための手段】[Means for solving the problem]

自転車のクランク軸上の駆動させるためのチェーンを回転させる大ギヤと対 面する反対側に、クランクとクランク軸受部分との間のクランク軸上に、フリー ホイールを駆動方向には自由回転して反対駆動方向には、フリーホイール内のつ めがフリーホイール外輪部内側の歯車を噛むように設けて、反対方向に対してフ リーホイール外輪部も共に回転するように設ける。更にフリーホイール外輪部下 部にはレバーを設けて、これに連結するブレーキロットを設け、ブレーキロット にはチェーンステーに接合したブレーキステーで吊り下げるようにして、ブレー キロットをキャリバーブレーキに結合する。 On the opposite side of the bicycle facing the large gear that rotates the chain for driving on the crankshaft, on the crankshaft between the crank and the crank bearing part, the freewheel freely rotates in the driving direction In the drive direction, the claws inside the freewheel engage the gears inside the freewheel outer ring, and the freewheel outer ring also rotates in the opposite direction. In addition, a lever is provided at the lower part of the outer ring of the freewheel, and a brake lot connected to it is provided. The brake lot is suspended by a brake stay joined to a chain stay, and the brake lot is connected to the caliber brake.

【作用】[Action]

上記の如く設けた(ブレーキ)装置は下記の如く働く。自転車のペダルを駆 動方向に踏めば自転車は走る。この時クランク軸上に設けたフリーホイールは自 由回転して何らの抵抗は全くない。しかし、一旦ペダルを逆方向に踏むとフリー ホイール内のつめがフリーホイール外輪部の内側にある歯車を噛んで、フリーホ イールの外輪部を逆回転させるために、フリーホイール外輪部下部に設けたレバ ーも同時に回転する。そこでレバーに連結したブレーキロットを引くから、これ に連結しているキャリバーブレーキが自転車の後輪リムを加圧して制動作用し自 転車を停車する。 The (brake) device provided as described above works as follows. The bicycle runs when you depress the pedal of the bicycle in the driving direction. At this time, the freewheel provided on the crankshaft rotates freely and there is no resistance. However, once the pedal is depressed in the reverse direction, the pawl inside the freewheel bites the gear inside the outer ring of the freewheel to rotate the outer ring of the freewheel in the reverse direction.ー also rotates at the same time. Therefore, the brake lot connected to the lever is pulled, and the caliber brake connected to this pressurizes the rear wheel rim of the bicycle to act as a brake and stop the bicycle.

【実施例】【Example】

一実施例として図1,図2上から説明すると、自転車のクランク軸(1)の 片側クランク(2)に付いている大ギヤ(13)の反対側になる、クランク軸受 とクランク(2)との間のクランク軸(1)上に、フリーホイール(ギヤ)(3 )を駆動方向に自由回転するように設ける。一方、フリーホイール(3)の外輪 部下部にはレバー(4)を設けて、これに連結したブレーキロット(5)を、チ ェーンステー(10)から吊り下げ用に設けたブレーキステー(6)で保持させ る。ブレーキロット(5)の端にはキャリバーブレーキ(7)を設けて、後輪リ ム(12)を加圧できるように設ける。 上記の如く構成すると、ペダル(9)を走行中に逆方向に踏めば、フリーホイ ール(3)内のつめ(15)が、フリーホイール(3)内の歯車(16)に噛み 込んで、フリーホイール(3)の外輪部にあるレバー(4)が回転するため、ブ レーキロット(5)を引いてキャリバーブレーキ(7)が後輪リム(12)を加 圧して制動する。尚、キャリバーブレーキ(7)に代えて後輪車軸上に設けたバ ンドブレーキを備えても同じ効果が得られる。 1 and 2 as one embodiment, a crank bearing and a crank (2) opposite to a large gear (13) attached to one side crank (2) of a crankshaft (1) of a bicycle are provided. A freewheel (gear) (3) is provided on the crankshaft (1) between the two so as to freely rotate in the driving direction. On the other hand, a lever (4) is provided on the lower portion of the outer wheel portion of the free wheel (3), and the brake lot (5) connected to the lever is connected to the chain stay (10) by a brake stay (6) provided for suspension. Hold it. A caliber brake (7) is provided at the end of the brake lot (5) so that the rear wheel rim (12) can be pressurized. With the above construction, when the pedal (9) is stepped in the opposite direction while traveling, the pawl (15) in the free wheel (3) engages with the gear (16) in the free wheel (3), As the lever (4) on the outer wheel of the freewheel (3) rotates, the brake lot (5) is pulled and the caliber brake (7) presses the rear wheel rim (12) to brake. The same effect can be obtained by providing a band brake provided on the rear wheel axle instead of the caliber brake (7).

【考案の効果】[Effect of device]

以上の如く設けたペダルブレーキ付自転車は、全く手を使わずに足でペダル を逆方向に踏むことで制動し停車させることができるから、手の不自由な者でも 安心して自転車に乗れるに至った社会的利益は多大である。 The bicycle with pedal brakes provided as described above can be stopped by stepping on the pedal in the opposite direction with your foot without using any hands, so even a handicapped person can ride a bicycle with peace of mind. The social benefits are great.
