Abstract
A truck trailer that can be loaded from the sides or from overhead and which allows cargo to be transported within an enclosure includes a trailer bed, and an enclosure that is linearly movable with respect to the trailer bed from a position in which the enclosure extends over the entire length of the trailer bed to a position in which substantially the entire trailer is uncovered. In certain embodiments, a roller and track mechanism is used for facilitating linear movement of the enclosure as a unit from an enclosing position to an open position.
Claims11
A truck trailer comprising:
- a flatbed trailer;
- and
- a non-collapsible enclosure defining sidewalls that extend upwardly adjacent side edges of the flatbed trailer, the non-collapsible enclosure being movable rearwardly along the length of the flatbed trailer, while at least partially supported on the trailer, between a position in which the enclosure extends over the entire length of the flatbed trailer and a position in which substantially the entire flatbed trailer is uncovered, thereby providing unfettered access to the trailer bed along the opposite sides of the trailer bed.
A truck trailer comprising:
- a flatbed trailer having a front end, a rear end and opposite sides;
- and
- a non-collapsible enclosure having opposite sidewalls, the non-collapsible enclosure being movable rearwardly along the length of the trailer, while at least partially supported on the trailer, between an enclosing position in which each of the opposite sidewalls extends upwardly adjacent a respective one of the opposite sides of the flatbed trailer between the front end of the flatbed trailer and the rear end of the flatbed trailer, and a cargo loading/unloading position in which the opposite sidewalls are located outwardly away from the rear end of the flatbed trailer, thereby providing unfettered access to the trailer bed along the opposite sides of the trailer bed.
A truck trailer comprising:
- a flatbed trailer having opposite sides and opposite ends;
- a non-collapsible enclosure including sidewalls extending upwardly from the sides of the flatbed trailer;
- and
- a mechanism facilitating movement of the enclosure as a unit rearwardly along the length of the trailer, while at least partially supported on the trailer, from an enclosing position in which the sidewalls extend upwardly from sides of the flatbed trailer to an open position in which the sidewalls are located outwardly away from the rear end of the flatbed trailer, thereby providing unfettered access to the trailer bed along the opposite sides of the trailer bed.
