    • A foldable walker apparatus includes a pair of spaced-apart inner frame members of two parts each hinged together, with a pair of link members diagonally extending therebetween. Each link has a bend extending upwardly and outwardly. The walker has support members that are arc-shaped with a seat extending between their apexes. A collapsible basket is provided with two end members each having a rigid peripheral portion connecting the frame members and a basket member of flexible fabric extending therebetween. A self-adjusting brake rod is provided with a gripping member spring- biased to remain free of the brake rod until the gripping member is operatively actuated to engage and thereby actuate the brake rod. A brake housing fully extends around a brake pad mechanism, including a means for connecting and adjusting the corresponding brake pad, to at least the outer periphery of one of the wheels for fully protecting the brake pad mechanism.
    • 可折叠助行器装置包括一对间隔开的两个部分的内框架构件,每个部分铰接在一起,一对连接构件在其间对角地延伸。 每个连杆具有向上和向外延伸的弯曲。 步行器具有支撑构件,其具有在其顶点之间延伸的座的弧形。 可折叠的篮子设置有两个端部构件,每个端部构件具有连接框架构件的刚性周边部分和在它们之间延伸的柔性织物的篮构件。 自调节制动杆设置有夹持构件,弹簧被偏压以保持没有制动杆,直到夹紧构件被操作地致动以接合并由此致动制动杆。 制动器壳体完全围绕制动衬块机构延伸,包括用于将相应的制动衬块连接和调节到至少其中一个轮的外周的装置,以完全保护制动衬块机构。

    • The present invention provides a propulsion assembly for a bicycle. The propulsion assembly includes a support member that at least extends from the bicycle frame to a distal end spaced-apart from the rear wheel. The assembly includes a first drive mechanism rotatably mounted on the frame and axially connected to the rear wheel for transmitting motion thereto. A second drive mechanism is rotatably mounted at the distal end of the support member and coupled with the first drive mechanism. Ratchet mechanisms axially extend from the second drive mechanism and connect to a pair of elongate members. The bicycle has pedal arms with pedals extending therefrom. The elongate members are pivotally, operatively connected to the pedals. The pedals with pedal arms are movable in a circular manner for transmitting rotational power to the elongate members for propelling the bicycle.
    • 本发明提供一种用于自行车的推进组件。 推进组件包括至少从自行车车架延伸到与后轮间隔开的远端的支撑构件。 组件包括可旋转地安装在框架上并且轴向连接到后轮的第一驱动机构,用于传递运动。 第二驱动机构可旋转地安装在支撑构件的远端并且与第一驱动机构联接。 棘轮机构从第二驱动机构轴向延伸并连接到一对细长构件。 自行车具有踏板臂,脚踏板从其延伸。 细长构件枢转地,可操作地连接到踏板。 具有踏板臂的踏板可以以圆形方式移动,以将旋转动力传递到细长构件以推动自行车。
