Abstract

<P>PROBLEM TO BE SOLVED: To prevent a bicycle for children, a stroller, and a wheelchair from running out of control on a downhill slope due to overspeed by attaching a centrifugal brake thereto to suppress the overspeed. <P>SOLUTION: A gear 1 is mounted on the hub part of a wheel. A ball bearing is fixed to a front fork. The gear 1 is moved when the wheel is rotated to rotate a gear 2. A shaft 4 interlocking with the gear 2 rotates the brake shoe of a centrifugal brake body 5. The brake shoe is expanded by a centrifugal force caused by the rotation to produce a friction on the side surface of a drum. Consequently, the bicycle for children, the stroller, and the wheelchair are prevented from being run out of control on a downhill slope due to overspeed. <P>COPYRIGHT: (C)2011,JPO&INPIT

Description

この発明は、子ども用自転車、ベビーカー、車椅子の過速度制御に関する。  The present invention relates to overspeed control of children's bicycles, strollers, and wheelchairs.

従来の子ども用自転車や、ベビーカー、車椅子には、車輪の回転を滑らかにするために、ボールベアリング等で構成されている。特に子ども用自転車では、よりスピードを得るために、変速機による速度調整機能も備わっている機種もある。これは、スピードを得るために開発されたものである。  Conventional children's bicycles, strollers, and wheelchairs are configured with ball bearings or the like in order to smooth the rotation of the wheels. Especially for children's bicycles, there are models that also have a speed adjustment function using a transmission in order to gain more speed. This was developed to gain speed.

特公昭６２−１３５３２ 回転軸の遠心ブレーキ装置
軸には、取付軸を介してシューがピンにより取付けられている。シューは、円形外周を有する一対のものからなっている。シューの外方にはばねが設けてあリ、ばねの両端はシューに固定してある。これにより、軸の回転速度が一定以上になると、シューはばねに抗して外方に拡大しケーシングの内面を圧し、ブレーキ作用が生じる。Japanese Patent Publication No. 62-13532 Centrifugal brake device of rotating shaft A shoe is attached to the shaft via a mounting shaft by a pin. The shoe is composed of a pair having a circular outer periphery. A spring is provided outside the shoe, and both ends of the spring are fixed to the shoe. As a result, when the rotational speed of the shaft exceeds a certain level, the shoe expands outward against the spring, presses the inner surface of the casing, and a braking action occurs.

しかしながら、以上の技術によれば、下り坂では、加速度的に速度が上がり、制御が不能に陥ることもあった。これにより、下り坂では、制御不能は速度に至る場合もあり、重大な事故につながりかねない。
そこで、この発明は、過速度を自動制御することにより、安全な子ども用自転車、ベビーカー、車椅子を提供することを課題とする。However, according to the above technique, on the downhill, the speed increases at an acceleration, and the control sometimes becomes impossible. This can lead to serious accidents on downhills, where loss of control can lead to speed.
Therefore, an object of the present invention is to provide a safe children's bicycle, stroller, and wheelchair by automatically controlling overspeed.

以上の課題を解決するために、請求項１の発明は、車輪に遠心ブレーキを装着したことを特徴とする子ども自転車である。また、請求項２の発明は、車輪に遠心ブレーキを装着したことを特徴とするベビーカーである。また請求項３の発明は、車輪に遠心ブレーキを装着したことを特徴とする車椅子である。  In order to solve the above problems, the invention according to claim 1 is a child bicycle characterized in that a centrifugal brake is mounted on a wheel. The invention of claim 2 is a stroller characterized in that a centrifugal brake is mounted on a wheel. The invention of claim 3 is a wheelchair characterized in that a centrifugal brake is mounted on the wheel.

請求項１、請求項２、並びに請求項３の発明によれば、一定の速度を超過すると、遠心力の作用により、ブレーキが作動する。このため、加速度が付かず、一定の速度が保たれる。  According to the invention of claim 1, claim 2 and claim 3, when a certain speed is exceeded, the brake is actuated by the action of centrifugal force. For this reason, acceleration is not applied and a constant speed is maintained.

この発明の一実施形態を示す斜視図である。It is a perspective view showing one embodiment of this invention. この発明の一実施形態を示す正面図である。It is a front view which shows one Embodiment of this invention.

この発明の一実施形態を、図１、及び図２に示す。
車輪のハブ部に歯車１が設置されている。フロントフォークには、ボールベアリングが固定されている。歯車１は、車輪の回転により動き、歯車２を回転させる。この歯車２に連動したシャフトが遠心ブレーキ本体のブレーキシューを回転させる。このブレーキシューは、回転の遠心力でひろがり、ドラムの側面に摩擦を生じさせる。One embodiment of the present invention is shown in FIGS.
A gear 1 is installed at the hub portion of the wheel. A ball bearing is fixed to the front fork. The gear 1 is moved by the rotation of the wheel to rotate the gear 2. The shaft interlocked with the gear 2 rotates the brake shoe of the centrifugal brake body. This brake shoe is expanded by the centrifugal force of rotation and causes friction on the side surface of the drum.

この実施形態によれば、車輪のハブ部に設置された歯車１は、歯車２を回転させ、さらに、連動するシャフトにより、遠心ブレーキ内のブレーキシューを作動させる。したがって、ブレーキシューが回転することにより、遠心力が生じ、広がったブレーキシューが、ドラムの内面に摩擦を生じさせ制動をかける。  According to this embodiment, the gear 1 installed in the hub portion of the wheel rotates the gear 2 and further operates the brake shoe in the centrifugal brake by the interlocking shaft. Therefore, centrifugal force is generated by the rotation of the brake shoes, and the spread brake shoes generate friction on the inner surface of the drum to apply braking.

（他の実施形態）
図１の実施形態では、自転車用の超過速度自動制御装置であったが、他の実施形態では、ベビーカーや手動式の車椅子の車輪に設置するものでも良い。(Other embodiments)
In the embodiment of FIG. 1, the bicycle overspeed automatic control device is used. However, in another embodiment, it may be installed on the wheel of a stroller or a manual wheelchair.
