ABSTRACT:
A portable ice skating rink comprises, in a kit, a plastic sheeting, a protective band for the sheeting, and a number of rigid tubular members, flexible connectors and corrugated clips. To assemble the kit, the tubular members are connected to each other in a closed loop using the flexible connectors inserted in facing ends thereof and with corners of the loop being formed by curving some flexible connectors. The sheeting is then laid over the ground of the area enclosed by the loop while extending outwardly over and past the loop. The protective band is laid over the sheeting opposite the loop and the clips are installed thereat to secure the sheeting to the so formed frame with the clips running continuously all along the frame such as to protect the sheeting. Portions of the frame can be raised to level it and the sheeting can then be pulled.
