Apparatus for extending the load carrying bed area of a truck

Claim 1

A trailer hitch and extension apparatus for extending a bed of a pickup truck having a width and that includes bed side walls with upper edges that define an upper plane and a horizontal surface between the bed walls that defines a lower plane, wherein the pickup truck has a bumper and a pivoting truck tailgate above the bumper that is movable between lowered, open and raised, closed positions, said apparatus comprising: a) a truck frame portion that includes a structural member for attaching a trailer hitch thereto; b) a longitudinal beam that extends away from the bumper and the truck bed in an operating position, the beam having proximal and distal end portions; c) a removable connector for securing the proximal end portion of the longitudinal beam to the structural member of the truck frame in an operating position; d) a transverse beam attached to the distal end portion of the longitudinal beam and extending about the width of the pickup truck bed; and e) left and right side wall extension members mounted respectively on opposite ends of the transverse beam, each side wall extension member being generally rectangular, having front and rear vertical edges and a lower edge that conforms to the lower plane of the truck bed horizontal surface and the tailgate when the tailgate is in the lowered position, and an upper edge that is adjacent the upper plane; f) the side wall extension members and the transverse beam surrounding an open space above the longitudinal beam that receives the truck tailgate in the lowered position and enables the truck tailgate to be raised or lowered; g) wherein the side wall extension members, the longitudinal beam, and the transverse beam form an extension frame during use that pivotally supports an auxiliary tailgate that pivots about a transverse line, said auxiliary tailgate being movable between open and closed positions, wherein in the closed position thereof the auxiliary tailgate is vertically oriented and abuts each of the rear vertical edges of said side wall extension members.

Claim 6

An apparatus for extending a pickup truck bed of a pickup truck that includes bed side walls with upper edges that define an upper plane and a horizontal bed surface with a width positioned between the bed walls that defines a lower plane, wherein the pickup truck has a frame that includes a bumper, a trailer hitch receiver socket mounted on the frame, and a pivoting truck tailgate mounted above the bumper that is movable between lowered, open and raised, closed positions, said apparatus comprising: a) a longitudinal beam that extends away from the frame at the bumper and the horizontal truck bed surface, the beam having proximal and distal end portions; b) the longitudinal beam including a removable connector for securing the proximal end portion of the longitudinal beam to the trailer hitch receiver socket in an operating position; c) a transverse beam attached to the distal end portion of the longitudinal beam and extending about the width of the horizontal bed surface; and d) left and right side wall extension members mounted respectively on opposite ends of the transverse beam, each side wall extension member being generally rectangular, having front and rear vertical edges and a lower edge that conforms to the lower plane and the tailgate when the tailgate is in the lowered position, and an upper edge that is adjacent the upper plane; e) the side wall extension members and the transverse beam surrounding an open space above the longitudinal beam that enables the tailgate to be raised or lowered; f) wherein the side wall extension members, the longitudinal beam, and the transverse beam form an extension frame during use that pivotally supports an auxiliary tailgate that pivots about a transverse line, said auxiliary tailgate being movable between an opened position and a closed position, wherein the auxiliary tailgate is vertically oriented and abuts each rear vertical edge of said side wall extension members when said auxiliary tailgate is in said closed position thereof.

Claim 7

An apparatus for extending a pickup truck bed of a pickup truck that includes bed side walls with upper edges that define an upper plane and a horizontal bed surface with a width positioned between the bed walls that defines a lower plane, wherein the pickup truck has a frame that includes a bumper, a trailer hitch receiver socket mounted on the frame, and a pivoting truck tailgate mounted above the bumper that is movable between lowered, open and raised, closed positions, said apparatus comprising: a) a longitudinal beam that extends away from the frame at the bumper and the horizontal truck bed surface, the beam having proximal and distal end portions; b) the longitudinal beam including a removable connector for securing the proximal end portion of the longitudinal beam to the trailer hitch receiver socket in an operating position; c) a transverse beam attached to the distal end portion of the longitudinal beam and extending about the width of the horizontal bed surface; and d) left and right side wall extension members mounted respectively on opposite ends of the transverse beam, each side wall extension member being generally rectangular, having front and rear vertical edges and a lower edge that conforms to the lower plane and the tailgate when the tailgate is in the lowered position, and an upper edge that is adjacent the upper plane; e) the side wall extension members and the transverse beam surrounding an open space above the longitudinal beam that enables the tailgate to be raised or lowered; f) wherein the side wall extension members, the longitudinal beam, and the transverse beam form an extension frame during use that pivotally supports an auxiliary tailgate that pivots about a transverse line, said auxiliary tailgate being movable between an opened position and a closed position, wherein the auxiliary tailgate is vertically oriented and abuts each rear vertical edge of said side wall extension members when said auxiliary tailgate is in said closed position thereof.
