  • Wheelchair, wheelchair apparatus and wheelchair care service network system
    Patent number: 8459677
    Abstract: A wheelchair includes a seat, one or more wheels and a seat weight sensing mechanism. The wheel includes a brake for stopping the wheel. The seat weight sensing mechanism is placed below the seat and is connected to the brake. When the seat is loaded by a weight more than a predetermined value, the seat weight sensing mechanism releases the brake to free the wheel. When the seat is not loaded by a weight more than a predetermined value, the brake stops the wheel.
    Type: Grant

  • PATIENT LIFT APPARATUS AND PATIENT LIFT SERVICE DISPATCH SYSTEM
    Publication number: 20120095777
    Abstract: A patient lift apparatus designed to lift and transfer patients is provided. The patient lift apparatus includes a patient lift base and a modular patient support device removably connected to the patient lift base to support a patient. The patient lift base includes a cantilever element, a portal frame, three wheel assemblies, a hanging mechanism. The cantilever element is pivoted intersectionally with the portal frame. The three wheel assemblies are disposed at the bases of the cantilever element and the portal frame, as three bearing points. The hanging mechanism is pivoted to the top of the cantilever element and connected to the modular patient support device below. When the cantilever element and the portal frame are rotated relatively, the height, the shape and the positions of the bearing points of the patient lift apparatus are changed accordingly.
