A wheelchair transport system and apparatus enables users to transport a wheelchair by way of a motorized, tadpole-configured tricycle. The wheelchair transport apparatus includes a main frame, a pivot assembly, and a lever arm assembly. The main frame includes an elongate frame member that attaches to a motorized tricycle. The pivot assembly includes pivot arm and chair support assemblies. The pivot arm assembly includes two pivot arms pivotally attached to the main frame. The chair support assembly includes two support members pivotally attached to the pivot arms. The lever arm assembly is attached to a forward pivot arm. Together, the lever arm assembly, the pivot arms, and the support arms are positionable intermediate a lowered position and a raised position. The raised positions enable the user to transport a wheelchair as supported upon the support arms. |

1. A wheelchair transport system for transporting a wheelchair by way of a motorized, tadpole-configured tricycle, the wheelchair transport system comprising in combination:
a tadpole-configured motorized tricycle, the tadpole-configured motorized tricycle comprising two laterally opposed front wheels, a rear wheel, a lateral trike plane, a maximum left lateral trike extent, a maximum right lateral trike extent, and a trike weight, the maximum left and right lateral trike extents being equidistant distant from the lateral trike plane at a select extent distance; and a wheelchair transport apparatus, the wheelchair transport apparatus comprising a main frame, a pivot assembly, a lever arm assembly, a maximum lateral apparatus extent, and an apparatus weight, the maximum lateral apparatus extent being no greater than the select extent distance, the main frame comprising an elongate frame member and attachment means for attaching the frame member to the motorized tricycle, 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 arm to the main frame via a pair of frame-fixed upper pivot axes, 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 being coaxial with a pair of frame-translatable lower pivot axes, the lever arm assembly being attached to the forward pivot arm, 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 manually moved from a rearward, lowered position to a forward, raised position, said raised positions for transporting a wheelchair having a wheelchair weight supported upon the support arms, the apparatus weight and the wheelchair weight being less than the trike weight, the trike weight and the maximum left and right lateral trike extents for maintaining the apparatus and said wheelchair in a uniform vertical position during transport, said wheelchair transport system for transporting said wheelchair by way of said motorized tricycle and wheelchair transport apparatus. |
