Abstract From the Canadian patent

A device for dividing a regular ice-hockey rink into at least two smaller rink parts comprises a plurality of straight sideboard sections (8a) and a plurality of curved sideboard sections (8b). The sideboard sections (8a 8b) are provided, with means (16, 20, 21) for interconnecting the same so as to form a supplemental sideboard (8, 9) to be placed across the regular ice-hockey rink e.g. essentially at the blue line. The supplemental sideboard together with the, stationary sideboard (1) enclose a smaller rink (5, 7) having substantially symmetrical curved corners.
