ABSTRACT:
The invention provides a portable ice skating rink including elongate curb structural members and a liner of flat flexible sheet material. The liner is economically made of sheet plastic for example with a bottom sheet and elongate sleeves around the periphery of the bottom sheet. The curb members, such as 4.times.4 lumber pieces, are inserted into an open end of each sleeve to form a water retaining structure. The sheet material and seams have resistance to water permiation sufficient to retain a shallow pool of water covering the bottom sheet during freezing in outdoor conditions to form an ice skating surface. Assembly of the rink is minimal. The user need only lay the liner in the intended location and slide the curb members into the preformed sleeves about the periphery. The interior depression formed is filled with water and allowed to freeze in outdoor conditions.
