  • Patent number: 6267452
    Abstract: A quick-release wheel hub assembly includes a hub with an axial hole. The hub further includes a compartment defined in each of two ends thereof, and the wall of one compartment includes a circular slot, each end of the hub further including a shoulder. Two bearings are mounted in the compartments, respectively. Each bearing has an end that bears against the shoulder of an associated end. A shaft is extended through the axial hole of the hub and the bearings. A sleeve is mounted around the shaft and positioned between the bearings. The sleeve may reliably prevent disengagement of the hub from the shaft. In addition, the strength of the shaft is improved. A c-shaped ring is mounted in the circular slot beside the other end of one bearing for fixing the bearing and preventing the bearing from dropping.

  • Patent number: 6193325
    Abstract: A fixing device for a hub and a tube of a baby stroller frame includes a hub including an axial hole having two ends, each end of the hub having a bearing mounted therein. A tubular shaft of an appropriate length includes a longitudinal hole having two ends, each end of the shaft including a compartment having a diameter greater than that of the longitudinal hole of the shaft. One of the ends of the shaft includes an outer periphery with an outer threading formed thereon. The other end of the shaft is extended beyond the hub and includes two radial holes, a ball being partially received in each radial hole and partially exposed beyond the radial hole. A core rod includes an enlarged first end and a second end with a neck portion and a groove. A spring is mounted around the core rod. A dust cap is a soft cap made of plastic material with resiliency to provide a chamber for receiving the enlarged first end of the core rod that is extended beyond the shaft.

  • Patent number: 6053525
    Abstract: A foldable baby stroller includes a main frame composed of a first section and a second section which is connected with each other by two retaining members. Two connection members are respectively pivotally connected to the first section by two position pins and are respectively secured to the second section. A U-shaped rear frame has two separating tubes and which are respectively connected to the two sections of the main frame. The retaining members are detachably connected to the second section so that when folding the stroller, the first section is pivoted to overlap onto the second section by disconnecting the retaining members from the second section, and the first section disconnecting from the separating tubes.

  • Patent number: 6000713
    Abstract: A foldable two-wheeled baby stroller includes two rear tubes, upper and lower seat rods connected to the rear tubes, a handle, a canopy support connected to upper ends of the handle, and two legs. Each end of the canopy support is pivotally connected to a connecting device, which, in turn, is securely connected to an arm of the handle. Each end of the seat rod is securely connected to a first connecting member, which, in turn, is pivotally connected to an associated rear tube. An upper end of each leg is securely connected to a second connecting member, which, in turn, is pivotally connected to the lower seat rod. When not in use, positioning pins are detached such that the legs, the seat rods, and the canopy rod can be pivoted to the storage positions which advantageous for storage and transportation.
