A collapsible bracing structure for bracing a load against shifting a surface bearing the load, including a pair of upright side frames extending longitudinally of the load-bearing surface and a plurality of elongated cross-braces each having opposite ends and extending laterally to the side frames to retain the side frames in an upright position. Manually operable, rotatable latches are provided for releasably attaching the opposite ends of each of the elongated braces to each of the side frames to define a rigid block having a bottom surface engaging the surface bearing the load and at least one upright load-engaging face.

A collapsible bracing structure for bracing a load against shifting on a surface bearing the load, the collapsible bracing structure comprising: a pair of laterally spaced frames extending in parallel on the load bearing surface, each frame having a pair of upright members connected by a plurality of vertically spaced transverse members; an elongated cross brace extending between the frames and releasably connected therewith to define a rigid parallelepiped for bracing a load, the cross brace being a generally L-shaped member having a substantially horizontal leg and a substantially vertical leg, said substantially horizontal leg contacting and resting on a transverse member on each frame when the bracing structure is assembled, said substantially vertical leg having a first notch engaged with one of the upright members of one side frame and a second notch engaged with one of the upright members of the other side frame whereby each upright member engaged with the substantially vertical leg fits within the corresponding notch to prevent lateral separation of the side frames; and a latch on at least one of the side frames and movable into overlying engagement with the substantially horizontal leg for maintaining engagement of the cross brace with the upright members.
