Abstract
Abstract A system is provided for quickly converting a floor area from one surface to another. A hard floor, typically wood, as for dancing, is covered by one or more detachable carpet sections located within an otherwise fully carpeted floor area. The carpet sections can be detached and removed to convert the underlying area into a dance floor. In one embodiment grooves are formed in the underlying floor and contain felt strips which lock with detachable, flexible locking strips attached to the carpet sections and which lock therewith when the carpet is installed. Hardened insert strips overlay the felt strips when the carpet is removed to provide a flat, smooth dancing surface.
