Lift system and apparatus for use with motorized tricycles

A wheelchair transport apparatus for transporting a wheelchair by way of a motorized tricycle, the wheelchair transport apparatus comprising:

• a main frame, the main frame comprising an elongate frame member and attachment means for attaching the frame member to a motorized tricycle, the frame member extending in a first dimension;
• a pivot assembly, the pivot assembly comprising a pivot arm assembly and a chair support assembly, the pivot arm assembly comprising a forward pivot arm, a rearward pivot arm and means for pivotally attaching the forward and rearward pivot arms to the main frame via a pair of upper pivot axes, the forward and rearward pivot arms extending in a second dimension, the upper pivot axes extending in a third dimension, the chair-support assembly comprising a forward support member, a rearward support member and means for pivotally and respectively attaching the forward and rearward support members to the forward and rearward pivot arms, the support members extending in the third dimension, and being coaxial with a pair of lower pivot axes;
• and
• a lever arm assembly, the lever arm assembly being attached to the forward pivot arm and extending upwardly in the second dimension, the lever arm assembly, the pivot arms, and the support arms being positionable intermediate a lowered position and a raised position, the pivot arms being rotatable about the upper and lower pivot axes, and the support members being raisable to the raised position from the lowered position when the lever arm assembly is moved from the lowered position to the raised position, the raised position for transporting a wheelchair supported upon the support arms.
