Floating fire pit

Abstract

Disclosed herein are components of a floating fire pit and methods of use of the floating fire pit to heat a volume of water. Specifically, embodiments of the floating fire pit include one or more tubular members, a base surface, and one or more sidewalls connecting the base surface to the one or more tubular members. The one or more tubular members enclose one or more volumes of air, and the floating fire pit has a buoyancy sufficient to float in the volume of water such that at least a portion of the one or more tubular member is above a surface of the volume of water and the base surface is below the surface of the volume of water.

1 . A floating fire pit comprising:
 at least one tubular member enclosing at least one volume of gas, wherein the at least one tubular member forms a closed perimeter;   a base surface positioned within a volume defined by the closed perimeter and extending in a vertical direction, wherein the base surface is below the at least one tubular member with respect to the vertical direction;   at least one sidewall extending between the at least one tubular member and the base surface,   wherein the floating fire pit has a buoyancy sufficient to float in a volume of water such that at least a portion of the at least one tubular member is above a surface of the volume of water and the base surface is below the surface of the volume of water.   
     
     
         2 . The floating fire pit of  claim 1 , further comprising:
 a support surface positioned above the base surface and within the volume defined by the closed perimeter.   
     
     
         3 . The floating fire pit of  claim 2  wherein the support surface is in the form of a grate with a plurality of openings formed by a plurality of intersecting ribs. 
     
     
         4 . The floating fire pit of  claim 3  wherein the plurality of openings are each between 0.5 inches by 0.5 inches and 2 inches by 2 inches. 
     
     
         5 . The floating fire pit of  claim 2 , further comprising:
 a bracket extending inward from one of the at least one sidewalls toward another of the at least one sidewalls,   wherein the support surface abuts the bracket to maintain a relative position above the base surface.   
     
     
         6 . The floating fire pit of  claim 1 , further comprising an anchor attachment extending away from a lower face of the base surface. 
     
     
         7 . The floating fire pit of  claim 6 , further comprising an anchor connected to the anchor attachment by a non-rigid member. 
     
     
         8 . The floating fire pit of  claim 1  wherein the at least one sidewall extends from the base surface to the at least one tubular member directly connecting the base surface to the at least one tubular member. 
     
     
         9 . The floating fire pit of  claim 8  wherein the at least one sidewall extends away from the base surface at an angle ranging between 120 degree and 150 degrees. 
     
     
         10 . The floating fire pit of  claim 1  wherein the buoyancy of the floating fire pit is sufficient to float in the volume of water when supporting an additional load of combustible material weighing up to 100 lbs. 
     
     
         11 . A method of heating a volume of water, the method comprising:
 disposing at least one tubular member enclosing a volume of gas on the volume of water such that at least a portion of the tubular member and enclosed volume of gas is above a surface of the volume of water;   disposing a base surface below the surface of the volume of water;   supporting combustible material above the base surface while the base surface is below the surface of the volume of water;   combusting the combustible material while the combustible material is supported above the base surface;   heating the base surface via heat generated by combustion of the combustible material; and   increasing a temperature of the volume of water via contact with the heated base surface.   
     
     
         12 . The method of  claim 11 , further comprising:
 positioning a support surface above the base surface and below the surface of the volume of water.   
     
     
         13 . The method of  claim 12 , further comprising:
 positioning the combustible material directly on the support surface.   
     
     
         14 . The method of  claim 13 , further comprising:
 moving combusted combustible material through one or more openings defined by the support structure and toward the base surface.   
     
     
         15 . The method of  claim 11 , further comprising:
 attaching an anchor to the base surface via an anchor attachment extending from a lower surface of the base surface.   
     
     
         16 . The method of  claim 11 , further comprising:
 heating the at least one tubular member via heat generated by combustion of the combustible material; and   increasing the temperature of the volume of water via contact with the at least one tubular member.   
     
     
         17 . The method of  claim 11 , further comprising:
 heating at least one sidewall connecting the base surface to the at least one tubular member via heat generated by combustion of the combustible material; and   increasing the temperature of the volume of water via contact with the at least one sidewall.
