    • An air pump for use with a chain-driven bicycle having a freewheel. The pump assembly comprises a pair of opposed cylinders and a double-ended piston rod mounted in a housing. The piston rod has a bearing slot which engages a crank pin on a crankshaft which is driven by a sprocket. Rotation of the sprocket reciprocates the double-ended piston rod in the cylinders. A hook-shaped extension of the housing fits over the top of the chain stay of the bicycle, and a vertically movable clamping member provided with a ratchet mechanism abuts the underside of the chain stay; a lever operated cam clamps the chain stay intermediate the hook portion and the clamping member. The lower run of the bicycle drive chain engages the drive sprocket of the pump assembly. Reverse rotation of the bicycle's crank assembly causes the conventional freewheel to also rotate in a reverse direction without rotating the wheel of the bicycle. The resulting movement of the chain over the drive sprocket of the pump rotates the drive sprocket, which reciprocates the double-ended piston rod in the cylinders and pumps air to an article to be inflated.
    • 一种用于带有自由轮的链条自行车的气泵。 泵组件包括一对相对的气缸和安装在壳体中的双端活塞杆。 活塞杆具有与由链轮驱动的曲轴上的曲柄销接合的轴承槽。 链轮的旋转将双端活塞杆往复运动。 壳体的钩形延伸部配合在自行车的链条的顶部上,并且设有棘轮机构的可垂直移动的夹紧构件邻接链条的下侧; 杠杆操作的凸轮夹持在钩部和夹紧构件之间的链条撑条。 自行车驱动链的下游接合泵组件的驱动链轮。 自行车曲柄组件的反向旋转导致常规的自由轮也可以相反地旋转而不旋转自行车的车轮。 链条在泵的驱动链轮上的所得运动使驱动链轮旋转,驱动链轮将双端活塞杆往复运动,并将空气泵送到要膨胀的物品上。

    • A manually operated pump for supplying air to a bicycle comprises an outer tube with one end closed and the other end open; a core tube which can slide in the outer tube and is provided with a piston assembly on one end; and a hose which can slide in the core tube. One end of the hose is connected with an air needle, and the other end is connected with an air nozzle assembly. The piston assembly comprises a piston, a piston ring, and a one-way valve communicating with the core tube and the outer tube. An end socket is provided on the other end of the core tube. A narrowing port is formed in the end socket of the core tube. A foot stand is hinged on outer side of the end socket of the core tube. The air needle has a head matching the narrowing port.
