S P E C I F I C A T I O N METHOD OF SECURING A PERIMETER FENCE AROUND AN ICE RINK WITHOUT EMBEDDING INTO GROUND ABSTRACT With the great increase in the game of ice hockey there is demand for large numbers of lower cost portable ice rinks that can make dual use of recreational land. Heretofore, the hockey "dasher" boards around the perimeter of the ice rink have had to be fastened by embedding into concrete or other special solid base in order to withstand the battering and collisions of players, resurfacing machines and hockey equipment as well as the expanding pressure of the ice as it is constantly melted and refrozen at its edges. This has meant special preparations and difficulty in dual use of recreational areas as playing field, tennis courts, lawn area, parking lot, etc. A method of securing the dasher boards into the refrigerated ice slab is disclosed so that no attachment is required into the ground below and no damage is done to it. The ice is frozen as a continuous slab extending out for a foot or so behind the boards, the boards being supported on cantilever metal posts which provide bonding with the ice and provision for re- frigerant piping underneath and behind the boards and a cover box is provided which not only covers the bonding ice behind the boards but also acts as a cover for refigerant header pipes instead of the usual expensive trench. Now for the first time unskilled personnel can completely assemble a refrigerated ice rink, make and maintain the ice, and then pack it away again at the end of the season, allowing for the alternate recreational area use to begin.
