Single-operator multi-function foldable transporter

Abstract

A system is disclosed including a transporter, having a top load bearing surface or bed, and four wheeled articulating legs, that may be operated by a single user/operator, and can be lowered or raised by changing the lengths or angles of its legs while maintaining the transporter bed level. The legs that may be folded up to be loaded onto or unloaded from a truck bed, or a stationary platform, by a single operator while carrying heavy load. The loading and unloading process is assisted by various safety brakes that prevent accidental slippage of the transporter off the truck bed. The legs' angles are changed using a dual-threaded lead screw. The transporter further includes two edge detectors on the front-end and the rear-end to detect the edge of the truck bed automatically, and prepare the folding of the transporter legs for loading onto the truck bed.
