Abstract: A receptacle is provided for holding a quantity of solid material. The receptacle includes a container having an open end, and a gate operably connected to the container so as to be rotatable to a closed position structured to prevent solid material from exiting the container through the open end. The gate includes a locking arm mounted thereon. A latching mechanism is operably connected to the container and includes a latch rotatable to a latched orientation structured to contact the locking arm to prevent the gate from being rotated out of the closed position. The locking arm is structured to move rearwardly and upwardly during rotation of the gate out of the closed position. The latch is structured so that contact between the latch and the locking arm when the latch is in the latched orientation prevents rearward and upward movement of the locking arm.

Abstract: A cargo trailer having a frame assembly with pivotally mounted wall structures or frames. The frame assembly can be collapsed into a compact shipping configuration wherein the wall structures are positioned substantially parallel with the floor structure of the trailer. Various parts of the cargo trailer can also be stowed in the collapsed frame assembly for shipment of the frame assembly and stored parts. After shipment of the cargo trailer, the wall structures are pivoted into their upright positions and the final assembly of the cargo trailer is completed. Exterior panels may be shipped together in a compact stack with the frame to the final assembly location where the panels are attached to the cargo trailer.
