Description
【０００１】[0001]
この考案は、簡便な構造で後ブレーキワイヤーの牽引力を増強させることがで きる自転車用ブレーキ倍力装置に関する。 The present invention relates to a bicycle brake booster capable of increasing the traction force of a rear brake wire with a simple structure.
【０００２】[0002]
従来、自転車では、ハンドル握りに設けたレバーを操作し、その動きを操作ワ イヤを介し後ブレーキに伝えて、後ブレーキを作動させるようにしている。 Conventionally, in a bicycle, a lever provided on a handlebar is operated, and its movement is transmitted to a rear brake via an operation wire so that the rear brake is activated.
【０００３】 しかし、このようにハンドル握りに設けたレバーを操作し、その動きをワイヤ ーを介し後ブレーキに伝えて、後ブレーキを動作させる機構では、制動が手の力 だけで行われるので、制動力が小さく、特に緊急時の判断が遅い幼児、高齢者等 については急停車ができず、思いがけない事故に遭遇することがあった。However, in such a mechanism in which the lever provided on the handle grip is operated and the movement thereof is transmitted to the rear brake via the wire to operate the rear brake, braking is performed only by hand force. Infants, elderly people, etc., who had a weak braking force and were particularly slow to make an emergency decision, could not stop suddenly and sometimes encountered an unexpected accident.
【０００４】 これに対して、可動のハンドル握りと、車体に取り付けた揺動機構と、上記ハ ンドル握りの動きを揺動機構に取り付けたローラを後車輪に接触させてローラを 後車輪により回転させる握り側操作ワイヤーと、ローラの回転を前車輪のブレー キ装置に伝えてブレーキ装置を作動させる車輪側操作ワイヤーを有する自転車の 制動力倍力装置が提案されている( 実公平3-56470 号公報) 。On the other hand, the movable handle grip, the swing mechanism attached to the vehicle body, and the roller attached to the swing mechanism for the above hand grip movement are brought into contact with the rear wheels to rotate the rollers by the rear wheels. A braking force booster for a bicycle has been proposed that has a grip-side operation wire that allows the wheel to rotate and a brake device that activates the brake device by transmitting the rotation of the roller to the brake device of the front wheel (Japanese Utility Model Publication No. 3-56470). Bulletin).
【０００５】[0005]
この装置においては、ハンドル握り操作によりワイヤーを牽引して揺動機構に 取り付けたローラを後車輪と接触させて後車輪に制動を掛け、且つこの際生ずる ローラの回転力で前車輪のブレーキ装置を作動させるものであり、したがってロ ーラを後車輪に確実に接触させなければ制動効果が半減するなどの問題点があっ た。 In this device, the wire attached to the swing mechanism is brought into contact with the rear wheels by pulling the wire by gripping the handle to brake the rear wheels and the braking force of the front wheels is used to brake the front wheels. Since it is operated, there is a problem that the braking effect is halved unless the roller is brought into contact with the rear wheel securely.
【０００６】 上記装置ではこのため揺動機構が複雑になり、複雑な割りには十分な制動力倍 力効果が得られない等の問題点がある。In the above device, therefore, the swing mechanism becomes complicated, and there is a problem that a sufficient braking force boosting effect cannot be obtained even if the mechanism is complicated.
【０００７】 そこで、この考案では簡便な構造で、十分な制動力が倍力されるような自転車 における制動力の倍力装置を提案することを目的とする。Therefore, it is an object of the present invention to propose a braking force booster for a bicycle, which has a simple structure and which can sufficiently boost the braking force.
【０００８】[0008]
以上の問題点を解決するため、この考案ではチェーンステーに設けられた取付 板に、操作杆の中央部を枢着させ、該操作杆の一端部には後ブレーキワイヤーを 結合し、該操作杆の他端部後車輪側には抵抗弾性体を取り付け、後ブレーキレバ ーの入力時には上記抵抗弾性体を回転する後車輪部に接触させて後ブレーキワイ ヤーの牽引力を増強させるようにした自転車用ブレーキ倍力装置を提案するもの である。 In order to solve the above problems, according to the present invention, the central portion of the operating rod is pivotally attached to the mounting plate provided on the chain stay, and the rear brake wire is connected to one end of the operating rod, and the operating rod is connected. The other end of the bicycle is equipped with a resistance elastic body on the rear wheel side, and when the rear brake lever is input, the resistance elastic body is brought into contact with the rotating rear wheel portion to enhance the traction force of the rear brake wire. It proposes a brake booster.
【０００９】[0009]
即ち、後ブレーキを入力すると、後ブレーキワイヤーは牽引されて、後ブレー キが作動するが、この考案では後ブレーキワイヤーの牽引によってこれを結合す る操作杆は中央部を支点として回動し、その他端に取り付けた抵抗弾性体を後車 輪部に接触し、この摩擦力により操作杆は後ブレーキワイヤーを牽引する方向に 回転させられ、これにより後ブレーキワイヤーの牽引力が増強される。 That is, when the rear brake is input, the rear brake wire is pulled and the rear brake operates, but in this invention, the operating rod that connects the rear brake wire by pulling the rear brake wire rotates about the central portion as a fulcrum, The resistance elastic body attached to the other end is brought into contact with the rear wheel portion, and due to this frictional force, the operating rod is rotated in the direction of pulling the rear brake wire, thereby enhancing the pulling force of the rear brake wire.
【００１０】[0010]
以下、この考案を図示の実施例に基づいて詳細に説明すると、１は自転車のハ ンドルバー、２はハンドルバー１の端部に設けられたハンドル握り、３はハンド ル握り２に並設された後ブレーキレバーで、後ブレーキレバー３はその基端部を ハンドルバー１に枢着させ、これを支点として入力時には矢印のようにハンドル 握り２側に引き寄せられる。 Hereinafter, the present invention will be described in detail with reference to the illustrated embodiment. 1 is a handlebar of a bicycle, 2 is a handle grip provided at an end of the handlebar 1, and 3 is a juxtaposed with a handle grip 2. With the rear brake lever, the rear end of the rear brake lever 3 is pivotally attached to the handlebar 1, and when this is used as a fulcrum, it is pulled toward the handle grip 2 side as indicated by the arrow.
【００１１】 ４は後ブレーキワイヤー、５は後ブレーキ、６は後ブレーキクランクで、後ブ レーキワイヤー４はその一端を後ブレーキレバー３に固定し、その他端を後ブレ ーキクランク６に固定されている。Reference numeral 4 is a rear brake wire, 5 is a rear brake, and 6 is a rear brake crank. One end of the rear brake wire 4 is fixed to the rear brake lever 3 and the other end is fixed to the rear brake crank 6. .
【００１２】 また、７は後車輪リム、８は後車輪タイヤ、９は後車輪部に設けられた後ブレ ーキ倍力装置で、後ブレーキ倍力装置９は操作杆10の中央部を支点としてその一 端部に後ブレーキワイヤー４を結合し、その他端部後車輪リム７側に抵抗弾性体 であるゴム体11を取り付けて構成される。Further, 7 is a rear wheel rim, 8 is a rear wheel tire, 9 is a rear brake booster provided on a rear wheel portion, and the rear brake booster 9 is a fulcrum at a central portion of the operating rod 10. As a result, the rear brake wire 4 is connected to one end thereof, and the rubber body 11 which is a resistance elastic body is attached to the other end rear wheel rim 7 side.
【００１３】 更に、チェーンステー12の後車輪部側には取付板13を斜め方向に溶接固定し、 この取付板13に操作杆10の中央部を枢着させる。Further, a mounting plate 13 is obliquely welded and fixed to the rear wheel portion side of the chain stay 12, and a central portion of the operating rod 10 is pivotally attached to the mounting plate 13.
【００１４】 以上のような構成において、自転車の走行時に後ブレーキレバー３がレバー入 力Ｐ1 で入力されると、後ブレーキワイヤー４、後ブレーキクランク６は矢印方 向に牽引されて後ブレーキ５はレバー入力Ｐ1 で作動する。In the above-described structure, when the rear brake lever 3 is input with the lever input P 1 while the bicycle is running, the rear brake wire 4 and the rear brake crank 6 are pulled in the direction of the arrow and the rear brake 5 is pulled. Operates with lever input P 1 .
【００１５】 しかし、この考案では操作杆10の取付板13はチェーンステー12に対して所定の 角度で斜め方向に溶接固定されており、したがって上述のようにワイヤー４が牽 引されると、ワイヤー４にその一端を結合した操作杆10は中央部を支点として回 動し、他端部に取り付けられたゴム体11が矢印方向に回転する後車輪リム７と接 触する。この結果摩擦力Ｐ2 が発生する。However, in this invention, the mounting plate 13 of the operating rod 10 is welded and fixed obliquely to the chain stay 12 at a predetermined angle. Therefore, when the wire 4 is pulled as described above, The operating rod 10 having its one end connected to 4 rotates about the central part as a fulcrum, and the rubber body 11 attached to the other end contacts the rear wheel rim 7 rotating in the arrow direction. As a result, a frictional force P 2 is generated.
【００１６】 この摩擦力Ｐ2 によって操作杆10はワイヤー４の牽引方向に回動させる、即ち ワイヤー４はレバー入力Ｐ1 に摩擦力Ｐ2 が加わった力で牽引され、この力で後 ブレーキクランク６が牽引される。The operating rod 10 by the frictional force P 2 is rotated in the winding direction of the wire 4, i.e. the wire 4 is pulled by the force applied frictional force P 2 on the lever input P 1, the rear brake crank in this force 6 is towed.
【００１７】 したがって、この考案では後ブレーキレバー３を軽い力で入力しても、ゴム体 11と後車輪リム７との摩擦力で強い制動力を確保できる。Therefore, in this invention, even if the rear brake lever 3 is input with a light force, a strong braking force can be secured by the frictional force between the rubber body 11 and the rear wheel rim 7.
【００１８】[0018]
以上要するに、この考案によれば簡便な構造で、ブレーキの制動力を増強でき るので、幼児、高齢者などの自転車に最適である。 In short, according to the present invention, the braking force of the brake can be increased with a simple structure, which is most suitable for bicycles for infants, the elderly and the like.
