Abstract:
1. A collapsible frame docking system, comprising: a first beam; a first cross-member; and a first hinged bracket that selectively secures the first beam to the first cross-member in either a first collapsible state in which the first cross-member is rotatable relative to the beam and a first expanded state in which the first cross-member is fixed relative to the beam; wherein the first hinged bracket includes an L-shaped bracket portion including a first plate extending in a first direction from a first end of the hinged bracket to a junction portion of the L-shaped bracket portion, wherein the first plate is fixedly secured to the cross-member in both the collapsible state and the expanded state, a second plate extending in a second direction, substantially perpendicular to the first direction, from the junction portion of the L-shaped bracket portion to a hinge portion of the L-shaped bracket portion, wherein the first and second plates are fixed relative to each other in both the collapsible state and the expanded state, the second plate is not fixed relative to the beam in the collapsible state, and the second plate is fixedly secured to the beam in the expanded state; a third plate that is fixedly secured to the beam in both the collapsible state and the expanded state; and a hinge that rotatably secures the third plate to the second plate such that, in the collapsible state, the cross-member is rotatable relative to the beam.
