Abstract
Resurfacing or conditioning of the ice surface of an ice rink in the area adjacent the edge of the ice and the kickboards defining the edge of the ice is carried out by a burner unit which applies a propane flame in a direction downwardly onto the ice in an area confined by a metal guide surrounding the flame. The unit melts the ice on the board and at the edge to prevent ice build up using a simple economic construction on a device which produces little or no toxic fumes.
Claims17
A method of maintaining an ice rink of the type used for sporting activities comprising a horizontal ice surface and a substantially vertical side surface defining an edge of the ice surface, the method comprising applying heat to the ice surface solely adjacent the edge so as to cause melting of the ice at the edge, and moving the application of heat along the edge so as to apply the heat in a narrow strip along the edge.
A method of maintaining an ice rink of the type used for sporting activities comprising a horizontal ice surface and a substantially vertical side surface defining one edge of the ice surface, the method comprising directing a flame onto the ice surface adjacent the edge so the contact of the flame on the ice surface causes melting of ice at the edge, moving the flame along the edge so as to cause melting of ice in a narrow strip along the edge and subsequently conditioning the ice surface using an ice conditioning machine having a working width wider than that of the narrow strip.
Apparatus for maintaining an ice rink of the type used for sporting activities comprising a horizontal ice surface and a substantially vertical side surface defining an edge of the ice surface, the apparatus comprising frame means, means for transporting the frame means around the ice surface at the edge, means mounted on the frame means for generating a flame from a combustible material and for directing the flame onto the ice surface adjacent the edge so as to apply heat thereto and a shroud member comprising a plurality of substantially vertical walls including a front wall and two side walls leaving an open base therebetween, at least one vertical side wall of the shroud member being arranged such that it is in use spaced from the ice surface by a short distance to allow the flame to extend under the side wall to said side surface.
