PROBLEM TO BE SOLVED: To provide a brake device that applies a brake when a handle of a cart is pushed, releases a brake when the handle is released, and releases a brake between carts when the carts make contact with each other, even for a cart having nesting function (for engagement).SOLUTION: A brake device for a handcart is formed in a structure in which a shaft is slidably inserted in a center of a cylindrical brake body 1 and a spring 3 is inserted inside or outside the cylindrical brake body of the shaft, a brake is released by lifting the cylindrical brake body by pulling a wire 51 with a lever mechanism 4, and a brake is applied by lowering of the cylindrical brake body with a returning force of the spring when tensile force of the wire is released. The brake device also comprises a pendulum-type lever for releasing the brake when handcarts contact make contact with each other.SELECTED DRAWING: Figure 2
【課題】ネスティング機能(連合させる)をもつカートでも、カートのハンドルを押せばブレーキが掛り、ハンドルを離せばブレーキが解除し、カート同士が接触すれば互いにブレーキが解除するブレーキ装置を提供するものである。【解決手段】筒状制動体1の中央部に軸を摺動可能に貫通し、該軸の筒状制動体の内部または外部にバネ3を挿入し、前記筒状制動体をレバー機構4でワイヤ51を引っ張って上昇させてブレーキを解除し、ワイヤの引っ張り力を解除すれば前記バネの復原力で筒状制動体が降下してブレーキが掛る構造にし、更に、手押し車同士が接触した際、ブレーキを解除する振り子式レバーを設けたことを特徴とした手押し車用ブレーキ装置である。【選択図】図2
