摘要：A fire-guard is provided for heating a room by convection using the heat from aradiation heat source, e.g. a fire place (1), and when the heat source is an open fire forpreventing sparks or other small particles of combustion from entering the room inwhich the fireplace is located. The fire-guard includes a plurality of spaced apart
substantially vertical pipes (4), having each at or near their lower end an inlet opening (6)and at or neartheir upper end (7) an outlet opening for air from the room. The portion ofthe fire-guard extending from its base to a height beyond the inlet openings constitutesa threshold for air flowing from the room towards the heat source. The pipes of at leastone pair of adjacent pipes of the fire-guard are hinged together for pivoting aboutthelongitudinal axis of at least one of the said two pipes.
