Abstract: A thermally insulated floor for a trailer includes a layer of parallel support beams. Each support beam is oriented in a direction substantially perpendicular to a forward direction of the trailer. A substantially planar panel of thermally insulating material is disposed on and supported by the layer of parallel support beams. A substantially planar layer of extruded aluminum is disposed on and supported by the panel of thermally insulating material. The support beams, the panel of thermally insulating material, and the layer of extruded aluminum are secured together.

Abstract: A trailer includes a front section having a first floor with an upper surface at a fixed vertical level approximately between three and six feet above a street level, a middle section, and a rear section having a second floor with an upper surface at the fixed vertical level. A horizontally-oriented platform is disposed in the middle section. A lifting mechanism is coupled to the platform and selectively raises and lowers the platform between a lower position of one to two feet above street level, otherwise known as curb-level, and an upper position of approximately between three and seven feet above street level.

Abstract: A corner post is for a rear door of a trailer, container or truck body. The corner post has a width when the door has been swung open 90 degrees between 0.75 inch and 1.94 inch such that the width of the opening into the trailer when both doors are open is at least 98.44 inches. The corner post includes three pieces that are attached together. The three pieces include planar sections and U-shaped sections.

Abstract: A transportation vessel includes a sidewall having a vertically oriented track on an interior side of the sidewall. The track extends upwardly to a top of the sidewall. A load bar has end(s) coupled to the track such that the end of the load bar is vertically slidable along the track. A stop bracket is positioned at a top of the track. The stop bracket includes a track extension and a stop piece. The track extension accommodates sliding of the load bar upwardly above the track. The stop piece blocks upward sliding of the load bar above the track extension.

Abstract: A transportation vessel includes a first sidewall and an opposing second sidewall. A load bar has a first end and a second end. The load bar is movable between a horizontal orientation and a vertical orientation. In the horizontal orientation, the first end is attached to the first sidewall and the second end is attached to the second sidewall, and the load bar may support cargo while the cargo is being transported in the transportation vessel. In the vertical orientation, the first end is attached to the first sidewall and the second end is unattached to the second sidewall.

Abstract: A thermally insulated floor for a trailer includes a layer of parallel support beams. Each support beam is oriented in a direction substantially perpendicular to a forward direction of the trailer. A substantially planar panel of thermally insulating material is disposed on and supported by the layer of parallel support beams. A substantially planar layer of wood is disposed on and supported by the panel of thermally insulating material. The support beams, the panel of thermally insulating material, and the layer of wood are secured together.

Abstract: A plug for insertion into a through hole of a king pin coupler plate of a trailer includes a body defining an axial direction and having an outer surface defining a perimeter with a distance around the perimeter. A plurality of pliable ears extend from the outer surface. The ears are each individually aligned in the axial direction. The ears each have a width that is less than ten percent of the distance around the perimeter of the outer surface of the body.

Abstract: A trailer includes a vertically-oriented sidewall, a horizontally-oriented roof panel disposed above the sidewall, and a top rail attached to the sidewall. At least a section of the top rail is disposed above the sidewall and below the roof panel. A substantially L-shaped cove has a horizontal leg attached to a lower surface of the roof panel, and a vertical leg attached to an inner surface of the sidewall. A board of thermal insulation includes an upper portion and a lower portion. The upper portion is disposed between the vertical leg of the cove and the section of the top rail, and the lower portion is disposed between the vertical leg of the cove and the sidewall.

Abstract: A sidewall construction arrangement for a trailer includes a plurality of upstanding panels. Each panel includes two opposing flanges. The flanges are disposed on opposing lateral edges of the panel. Adjacent flanges of two adjacent panels partially overlap each other. Each of a plurality of vertically oriented logistics posts includes two lateral margins. A first of the margins is attached to a respective first of the flanges of the two partially overlapping panels. A second of the margins of the post is attached to each of the first and second flanges of the two partially overlapping panels.

Abstract: A sidewall construction arrangement for a trailer includes a plurality of upstanding sidewall panels. Each of a plurality of vertically oriented posts is disposed between and engages a respective substantially coplanar pair of the panels. Each post has an exterior surface that is entirely continuous in a vertical cross-sectional view throughout a portion of the post that extends beyond the panels in a lateral direction.

Abstract: A trailer includes a pair of vertical, spaced apart opposing sidewalls and a roof sheet extending between and mounted atop the sidewalls. The sidewalls and roof sheet cooperate to define a cargo space. The roof sheet has an interior surface facing the cargo space and an opposing exterior surface. A plurality of bows are mounted to the exterior surface of the roof sheet and extend between the sidewalls. The plurality of bows support the roof sheet. Each bow includes at least three contact portions attached to the exterior surface of the roof sheet. A rib portion interconnects the contact portions and defines a channel between the rib portion and the exterior surface of the roof sheet.
