Collapsible mat assemblies
An assembly has a foldable frame member that has a folded and an unfolded orientation, a sheet material covering portions of the frame member when the frame member is in the unfolded orientation, and one or more floatation devices. The floatation devices can be attached to any number of locations, including but not limited to the sheet material, the top of the sheet material, the bottom of the sheet material, and the periphery of the frame member.
1. A method of deploying a collapsible floating assembly, comprising:
a. providing an assembly, comprising:
a foldable frame member that has a folded and an unfolded orientation, the frame member defining a periphery for the assembly;
a sheet material covering portions of the frame member when the frame member is in the unfolded orientation;
a first inflatable floatation device coupled to the sheet material or the frame member;
a second inflatable floatation device coupled to the sheet material or the frame member at a location that is separate from, and spaced apart from, the first inflatable floatation device;
ii. while the frame member is in the unfolded orientation, varying the inflation of the first and second inflatable floatation devices so that the assembly is partially submerged in water at the location of the second inflatable floatation device and the assembly is supported entirely above water at the location of the first inflatable floatation device when the assembly is placed in a body of water; and
iii. twisting and folding the frame member to the folded orientation where the frame member forms a plurality of concentric frame members.
