Patio heater with reflective shield

Abstract

Patio heater comprising a base portion adapted to accommodate a heat source, a reflector dome, a support system for the reflector dome, a heat generator and a reflective shield, wherein the reflector dome is above the heat generator to reflect heat downwards and a reflective shield coats the reflector dome, wherein the coating is comprised of a layer of stone insulation.

What is claimed is: 
     
         1 . An attachment for patio heaters, the heaters having a base including a chamber for a heat source and an upright stem, the attachment comprising:
 a. a dome member defined by a perimeter edge extendable from the upright stem, the dome member having an interior and exterior surface; and   b. a layer of stone insulation affixed along the perimeter edge of said dome member and to the interior surface of said dome member.   
     
     
         2 . The attachment of  claim 1  wherein the stone layer of insulation is affixed to the dome member using a bonding agent that is mixed with the insulation layer. 
     
     
         3 . The attachment of  claim 1  wherein the dome member is permanently attachable to the upright stem. 
     
     
         4 . The attachment of  claim 1  wherein the dome member is removably attachable to the upright stem. 
     
     
         5 . The attachment of  claim 1  wherein the thickness of the layer of stone insulation is from about 0.64 cm to about 1.27 cm. 
     
     
         6 . The attachment of  claim 1  wherein the thickness of the layer of stone insulation is from about 0.635 cm to about 0.825 cm. 
     
     
         7 . The attachment of  claim 1  wherein said dome member is generally rectangular perimeter shape and a pyramid-shaped central portion. 
     
     
         8 . The attachment of  claim 1  wherein said dome member is a generally circular perimeter shape and a curved central portion. 
     
     
         9 . The attachment of  claim 1  wherein said dome member has a generally oval perimeter shape and a curved central portion. 
     
     
         10 . A patio heater comprising:
 a. A base including a chamber for a heat source;   b. An upright stem;   c. A heat redirector attachment extending from the upright stem comprising:
 i. a dome member defined by a perimeter edge positionable atop of the burner unit, the dome member having an interior and exterior surface; and 
 ii. a layer of stone insulation affixed along the perimeter edge of said dome member and to the interior surface of said dome member. 
   d. A heat generating device positioned inside said dome member.   
     
     
         11 . The patio heater of  claim 10  wherein the interior surface of the dome faces downward towards the base. 
     
     
         12 . The patio heater of  claim 10  wherein the heat source is at least one propane tank. 
     
     
         13 . The patio heater of  claim 10  wherein the heat generating device is a series of heated coils. 
     
     
         14 . The patio heater of  claim 10  wherein the stone layer of insulation is affixed to the dome member using a bonding agent that is mixed with the insulation layer. 
     
     
         15 . The patio heater of  claim 10  wherein the dome member is permanently attachable to the upright stem. 
     
     
         16 . The patio heater of  claim 10  wherein the dome member is removably attachable to the upright stem. 
     
     
         17 . The attachment of  claim 1  wherein said dome member is generally rectangular perimeter shape and a pyramid-shaped central portion. 
     
     
         18 . The attachment of  claim 1  wherein said dome member is a generally circular perimeter shape and a curved central portion. 
     
     
         19 . The attachment of  claim 1  wherein said dome member has a generally oval perimeter shape and a curved central portion. 
     
     
         20 . A combination patio heater and heat redirection device, comprising:
 a. A base including a chamber for containing a heat source;   b. A means for extending upwardly from said base, said mean for extending having a first lower end attached to said base and an upper end;   c. A dome member defined by a perimeter edge positionable along said upper end, the dome member having an interior and an exterior surface;   d. A layer of stone insulation affixed along the perimeter edge of said dome member and to the interior surface of said dome member; and   e. A heat generating device positioned inside said dome member.
