  • Patent number: 4038834
    Abstract: An ice skating arena is described having a skating area arranged to define a plurality of individual ice rinks and interconnecting bridging sections. Cooling means are provided below the said ice skating area and are arranged to provide a continuous ice covering over said rinks and bridging sections in use. Barrier means are provided in association with each said bridging section. Each barrier means is adapted to be selectively positioned across the associated section or to be moved to a non-obstructing position to allow free skating over the section, whereby with all of the barrier means positioned across the associated sections, the individual rinks can be used as self-contained skating areas, or with all of the barriers moved to said non-obstructing positions, skaters can pass freely between the rinks by way of said bridging sections.
