ABSTRACT OF THE DISCLOSURE A frame of a modular portable rink for holding a plastics sheet on the ground is basically of the type of a box-shaped, enclosed cross-sectional configuration composed of two generally identical structural shaped members disposed in a staggered relationship so that the abutment areas at the inside of the frame and at the outside thereof alternate to eliminate the need for special connectors between abutted parts of the frame. The only fasteners required are stakes driven at predetermined intervals through preformed holes in the respective elements. The invention simplifies the overall structure of the frame while enhancing its rigidity.
