    • A wheel jack comprises a frame, a pair of dowels rotatable with respect to the frame, threaded connectors, each threaded connector mounted on a corresponding dowel, a pair of lever arms movable between a retracted position and an extended position, and a pair of axles, each axle mounted on a corresponding lever arm, wherein the axles are adapted to support a wheel. Rotation of the dowels urges the corresponding threaded connector to move along the dowel, and each threaded connector is pivotably connected to a corresponding lever arm. In operation, the wheel jack is placed under a tire, the axles are raised to engage the wheel so as to lift the wheel off its corresponding wheel mount, and then the wheel is removed from a motor vehicle.
    • 车轮千斤顶包括框架,相对于框架可旋转的一对销钉,螺纹连接器,安装在相应销钉上的每个螺纹连接器,可在缩回位置和延伸位置之间移动的一对杠杆臂,以及一对轴 每个轴安装在相应的杠杆臂上,其中所述轴适于支撑车轮。 销的旋转促使相应的螺纹连接器沿着定位销移动,并且每个螺纹连接器可枢转地连接到相应的杠杆臂。 在操作中,车轮千斤顶被放置在轮胎下方,轴被升高以接合车轮,以便将车轮从其相应的车轮安装件上提起,然后车轮从机动车辆移除。

    • A small, compact, collapsible three-wheeled truck which can be used to support a flat or damaged tire of a vehicle while the latter is being driven to a repair location. The truck has a foldable ramp which rests flat on the ground while the rear wheels are in slightly raised position, so as to prevent movement of the truck while the flat tire is being driven onto it. As the ramp pivots upwardly into retaining position behind the tire, the rear wheels are lowered into ground contacting position. Simultaneously, an extension attached to the ramp causes a retaining member near the front of the truck to pivot upwardly out of the way of the tire into front retaining position. The tire after mounting rests in a cradle and is prevented from moving forwardly or rearwardly with respect to the truck.
    • 一种小型,紧凑的,可折叠的三轮车,可用于支撑车辆的平坦或损坏的轮胎,同时将车辆驱动到修理位置。 该卡车具有可折叠的斜坡,其平放在地面上,而后轮处于略微升高的位置,以防止在平坦的轮胎被驱动到其上时卡车的移动。 当斜坡向上枢转到轮胎后面的保持位置时,后轮下降到地面接触位置。 同时,附接到斜坡的延伸部使得靠近卡车前部的保持构件向上枢转,从轮胎的方式向前转动到前保持位置。 安装后的轮胎搁置在支架中,并且防止相对于卡车向前或向后移动。
