US 12,583,497 B2 · 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.

A single-operator transporter, comprising:

a transporter bed with adjustable height to carry cargo;
lockable front legs to carry a front-end weight of the cargo;
and
lockable rear legs to carry a rear-end weight of the cargo;
wherein
a push on a rear end of the transporter by a single operator, without directly actuating a release component for the front legs, unlocks the front legs to rotate backwards with respect to the transporter bed lifting the front legs off from ground, and allows the transporter to be loaded onto a raised platform wherein a height of the transporter bed is adjusted to a height of the raised platform.
