Abstract
Abstract A free standing thermal reflector apparatus is provided. When the apparatus is inserted into a fireplace and a fire is lit, heat from the fireplace is reflected into the room in which the fireplace is located. The apparatus includes reflector panels supported by a frame. To facilitate cleaning or replacement of the reflector panels, means are provided for their easy attachment to the frame of the apparatus. The reflector panels are made from highly polished stainless steel panels which may be glass coated to both increase the reflectivity of the reflector surface and to protect it from corrosion and oxidation.

Claim 1
Independent Claim
211 words
A free standing fireplace reflector apparatus for reflecting radiant heat energy into the room in which the fireplace is located, comprising: a rear frame, including a pair of legs, receiving a first reflector panel; and a pair of side frames, pivotally connected to said rear frame so that the apparatus may be adjusted to fit into fireplaces having different side angles, each of said side frames having a leg connected thereto at the end opposite from said pivot; said frames receiving respectively a second and third reflector panel; each of said side frames and said rear frame including: an upper horizontal grooved member and a lower horizontal grooved member receiving and slidably engaging one of said panels in said grooves; and a pair of vertical members connected to their respective upper and lower grooved members at the opposite ends thereof, wherein each of said pairs of vertical members includes one vertical member having a groove therein receiving an end of a reflector panel when said panel is positioned in said frame and one vertical member having a slot therein permitting said panel to pass therethrough so that said panel is properly positioned to slide between the upper and lower grooved members into the vertical grooved member in each of said frames.
