Packaging cushion device having modular cushion units

A packaging cushion device to be disposed inside a box for packaging a foldable housing, the housing having a folded configuration and an unfolded configuration, and being formable into rectangular bodies having different heights, said packaging cushion device comprising:

• four base members each having a base wall, a first sidewall, and a second sidewall, said base wall having first and second edges forming a corner therebetween, said first and second sidewalls being perpendicular to said base wall and connected respectively to said first and second edges, said first and second sidewalls being spaced apart from said corner to define a receiving corner portion therebetween;
• and
• four modular components each having a base panel, a first side panel, a second side panel, a first projection, and a second projection, said base panel having first and second lateral ends forming a corner therebetween, each of said modular components defining a reference point at a juncture between said first and second lateral ends, a first direction that extends perpendicularly away from said base panel and from said reference point, and a second direction extending along said second lateral end and away from said first lateral end, said first and second side panels extending respectively from said first and second lateral ends along said first direction, each of said first and second projections having a shape complementary to that of said receiving corner portion of a respective one of said base members, said first projection extending along said first direction from a part of said first side panel and a part of said second side panel both of which are adjacent to said reference point, said second projection extending along said second direction from said second side panel and an edge of a part of said base panel adjacent to said second side panel,
• wherein each of said base members may be assembled with one of said modular components to form a first modular configuration adapted for packing the housing in the folded configuration and to cover respectively four sets of corners of the housing, each of said sets having two adjacent top and bottom corners of the housing, and
• wherein each of said base members may be assembled with one of said modular components to form a second modular configuration adapted for packing the housing in the unfolded configuration and to cover respectively the four sets of corners of the housing.

A packaging cushion device to be disposed inside a box for packaging a foldable housing, the housing having a folded configuration and an unfolded configuration, and being formable into rectangular bodies having different heights, said packaging cushion device comprising:

• two base members each having a base wall, a first sidewall, a second sidewall, and a third sidewall, said base wall having first and second edges forming a corner therebetween, and a third edge forming another corner with said second edge oppositely of said first edge, said first, second and third sidewalls being perpendicular to said base wall and connected respectively to said first, second and third edges, said first and second sidewalls being spaced apart from said corner to define a first receiving corner portion therebetween, said third and second sidewalls being spaced apart from said another corner to define a second receiving corner portion therebetween, said second sidewalls being longer than said first and third sidewalls;
• four modular components each having a base panel, a first side panel, a second side panel, a first projection, and a second projection, said base panel having first and second lateral ends forming a corner therebetween, each of said modular components defining a reference point at a juncture between said first and second lateral ends, a first direction that extends perpendicularly away from said base panel and from said reference point, and a second direction extending along said second lateral end and away from said first lateral end, said first and second side panels extending respectively from said first and second lateral ends along said first direction, each of said first and second projections having a shape complementary to that of said first or second receiving corner portion, said first projection extending along said first direction from a part of said first side panel and a part of said second side panel both of which are adjacent to said reference point, said second projection extending along said second direction from said second side panel and an edge of a part of said base panel adjacent to said second side panel;
• said first and second receiving corner portions of each of said base members receiving respectively said first projections or said second projections of two of said modular components;
• wherein each of said base members may be assembled with two of said modular components to form a first modular configuration adapted for packing the housing in the folded configuration and to cover two of four sets of corners of the housing, each set having two adjacent top and bottom corners of the housing;
• and
• wherein each of said base members may be assembled with two of said modular components to form a second modular configuration adapted for packing the housing in the unfolded configuration and to cover two of the four sets of corners of the housing.
