Body Movably Supported Relative To Wheels Patents (Class 280/47.41)
  • Patent number: 7832744
    Abstract: A stroller includes a main frame, a backrest, a backrest adjustor, and a linkage device. There is a guide rail formed inside the backrest adjustor. A positioning part of the backrest engages with the guide rail. When a handle of the linkage device is moved upward, a connecting component of the linkage device drives a pushing component of the linkage device to move upward along a supporting rod of the backrest. Accordingly, a protruding portion of the pushing component drives the backrest adjustor to rotate relative to a supporting frame of the main frame so as to release the positioning part from the guide rail.

  • Patent number: 7798516
    Abstract: A changing table that is secured to most types of conventional baby carriages. The changing table is deployed from a fixed position on the baby carriage to take into account the proper weight, size and space requirements necessary to change a small child. When the changing table is not in use, it may be retracted and ultimately stowed into the baby carriage in an unobtrusive position. In this manner, the changing table becomes a useful, mobile alternative to those people who typically must seek out a safe, clean and adequate surface to change their small children.

  • Patent number: 7716759
    Abstract: A patient transport apparatus. The patient transport apparatus of the present invention is articulated and sized to fit between the body and the open door of virtually all vehicles. Further, the patient transport apparatus uses a height-adjustable seat that is aligned with the vehicle seat to allow for simplified extraction of the patient from the vehicle. The height-adjustable seat lowers to just above ground height making the recovery of a fallen patient easier. A set of casters allows omni-directional travel of the patient transport apparatus for precise placement and a pair of primary motion wheels makes linear travel easier while providing a turning radius substantially approaching zero.

  • Patent number: 7396027
    Abstract: The self-braking wheelbarrow of the present invention comprises a wheelbarrow bin assembly mounted so as to pivot relative to an undercarriage assembly whereby the bin assembly interferes with the wheels on the undercarriage assembly causing a friction on the tread of the wheel and restricting the rotation of the wheel. In normal usage the undercarriage assembly is secured to the wheelbarrow bin assembly by securing latches. Braking is accomplished by selectively releasing securing latches, thereby permitting the wheelbarrow to pivot, and lifting the handles as if to move the wheelbarrow. The braking force applied to the tread on the wheel is proportional to the bin load thereby resulting in higher braking force with higher bin loads.
