ABSTRACT:
A tricycle powered wheelchair carrier has a platform supported on the bight of a U-shaped axle between a pair of rear wheels supported at the ends of the axle legs. The platform is formed with a downwardly sloping ramp portion at the end extending beyond the rear wheels. A front wheel is connected to handlebars at the front of a platform by a linkage pivoted at the top. A front actuator is connected between this linkage and the platform. A rear actuator is connected between the U-shaped axle and the platform. A transmission couples an internal combustion engine to a rear wheel and includes a reverse gear. A locking bar has rear and side mutually perpendicular arms. The side arm is pivotal about a horizontal axis in bearings on the side of the carrier to allow the side arm to move from a vertical position to a horizontal position against the rear wheels of a wheelchair on the platform with the end of the rear arm having a stud seated in a socket attached to the other side of the carrier. Front and side stops are provided to prevent motion of the wheelchair in the forward direction or side to side. These stops contact the front of left and right rear wheelchair tires and the sides of the rear wheelchair tires.
