ABSTRACT:
An inflatable skating rink made up of a plurality of base modules positioned adjacent to one another to define a perimeter of the skating rink. Base modules are made of a flexible material which is substantially impermeable to air. The base modules can be conveniently inflated and deflated. The adjacent base modules include air portals for providing a fluid passageway between the interior of the two adjacently positioned base modules so that the base modules can be mutually inflated and deflated. The adjacent base modules may be connected together in a manner so that they may be separated from one another during disassembly of the skating rink.
