Abstract
A hand truck comprising an elevating load platform and a carrying frame used to transport heavy and bulky loads on a back of a user. Automated lowering and rising of the platform is accomplished by a threaded rod that runs vertically along a rear spine of the hand truck frame. The rod is connected to an electric motor operated by a small rechargeable battery carried on board. A shoulder harness is provided directly below a handle assembly enabling the user to place the loaded hand truck on their shoulders. Activation of the raised platform elevates the load to the shoulder area where it can be carried more comfortably and safely.

A shoulder-mounted hand truck comprising:
- a stationary portion, comprising:
- first and second tracks in a parallel orientation to each other;
- a lead screw attached to said motor and positioned between said first and second tracks respectively;
- first and second shoulder braces attached to said first and second tracks respectively;
- and,
- a T-shaped guard attached to said first and second tracks;
- a retractable portion attached to said stationary portion;
- a motor;
- a stationary platform attached to said stationary portion;
- and,
- first and second shoulder braces attached to said stationary portion respectively;
- wherein said stationary portion comprises:
- first and second tracks in a parallel orientation to each other;
- a lead screw attached to said motor and positioned between said first and second tracks respectively;
- first and second shoulder braces attached to said first and second tracks respectively;
- and,
- a T-shaped guard attached to said first and second tracks;
- wherein activation of said motor causes said retractable portion to linearly slide towards and away from said stationary portion while said first and second shoulder braces are adapted to be positioned on an upright user's shoulders;
- and,
- wherein each of said stationary and retractable portions is adapted to be arranged in a vertical position with respect to the upright user.
A shoulder-mounted hand truck comprising:
- a stationary portion;
- a retractable portion adjustably attached to said stationary portion;
- a motor operably engaged with said retractable portion;
- a stationary platform attached to said stationary portion;
- and,
- first and second shoulder braces attached to said stationary portion respectively;
- wherein said stationary portion comprises:
- first and second tracks in a parallel orientation to each other;
- a lead screw attached to said motor and positioned between said first and second tracks respectively;
- first and second shoulder braces attached to said first and second tracks respectively;
- and,
- a T-shaped guard attached to said first and second tracks;
- wherein activation of said motor causes said retractable portion to linearly slide towards and away from said stationary portion while said first and second shoulder braces are adapted to be positioned on an upright user's shoulders;
- and,
- wherein each of said stationary and retractable portions is adapted to be arranged in a vertical position with respect to the upright user.
A method of utilizing a shoulder-mounted hand truck, said method comprising the steps of:
- providing a stationary portion comprising first and second tracks in a parallel orientation to each other, a lead screw positioned between said first and second tracks respectively, first and second shoulder braces attached to said first and second tracks respectively and, a T-shaped guard attached to said first and second tracks;
- providing and adjustably attaching a retractable portion to said stationary portion;
- providing and attaching a motor to said lead screw of said stationary portion;
- operably engaging said motor with said retractable portion;
- providing and attaching a stationary platform to said stationary portion;
- providing and attaching first and second shoulder braces to said stationary portion respectively;
- positioning an object on said stationary platform;
- arranging each of said stationary and retractable portions in a vertical position with respect to an upright user by positioning said first and second shoulder braces on the upright user's shoulders;
- and,
- activating said motor and thereby causing said retractable portion to linearly slide towards and away from said stationary portion.
