Expandable Trailer Vehicle

摘要

An expandable trailer vehicle is provided. The trailer vehicle comprises a wheeled vehicle frame that is adapted to be towed by a towing vehicle. The vehicle frame supports an expandable trailer structure having a front and rear wall, a floor, and a roof. The trailer structure includes expandable sections from the sides thereof, whereby a pair of L-shaped expandable side sections pivots outward from the sides of the trailer structure and form the floor and outer walls when deployed. Pivoting sidewalls pivot forward and rearward from the sides of the trailer structure to form the front and rear walls of the expanded section, closing out the L-shaped side sections when in a deployed state. A pair of side section roof surfaces extends from the roof of the trailer vehicle to close off the upper surface of the L-shaped side sections when in a deployed state.

1) An expandable trailer vehicle, comprising:
a vehicle frame supporting an expandable trailer structure, the vehicle frame having one or more sets of wheels, a rear end, and a front end having a towing vehicle attachment device; the expandable trailer structure comprising a front wall, a rear wall, a floor, and a roof extending therebetween, the roof extending from the rear end of the vehicle frame to substantially the front end; a first and second expandable side section having a substantial L-shape, wherein the expandable side sections comprise a first wall and a second wall, whereby each first wall is pivotably connected at a lower end to a side of the trailer structure via a longitudinal hinge; the expandable side sections having a stowed state and an expanded state; the stowed state of each expandable side section being in which the first wall is substantially vertically disposed between the front wall and rear wall of the trailer structure, and the second wall is substantially horizontally disposed between the front wall and rear wall of the trailer structure and substantially coextensive with the roof of the trailer structure. the expanded state being in which the first wall is pivoted downward from a vertical to a horizontal state from one side of the trailer structure such that the first wall is substantially in plane with the floor of the trailer structure and the second wall is substantially vertical; a first and second pivoting sidewall disposed along each side of the trailer structure, wherein the pivoting sidewalls are disposed between the front wall and rear wall of the trailer structure; the first pivoting sidewalls of each side of the trailer structure having a pivot point adjacent to the front wall of the trailer structure via a vertical hinge; the second pivoting sidewalls of each side of the trailer structure having a pivot point adjacent to the rear wall of the trailer structure via a vertical hinge; a first and second side section roof surface being slidable from a cavity within the roof of the trailer structure, whereby the roof surfaces extend laterally outward from the trailer structure and secure to the expandable side sections and the pivoting sidewalls to form enclosed trailer expansion portions along both sides of the trailer structure.
