For a stable, easy-to-handle fire basin for burning wood and similar fuels, consisting of a plurality of segments ( 1 a ) which are supported on the ground with feet ( 2 ) and towards the top have a plurality of segment surfaces ( 1 b ) to form the tub-shaped fire basin ( 1 ), the invention proposes that the segment surfaces ( 1 b ) of the fire basin ( 1 ) also have or form concave depressions or recesses.
1. A fire bowl for the combustion of wood and similar fuels, comprising a plurality of segments which are supported on the ground with feet and have a plurality of segment surfaces towards the top to form the trough-shaped fire bowl, wherein each segment surface of the fire bowl additionally has a concave trough, wherein the segment surfaces have intersecting bends for forming the troughs, and wherein each segment is formed from a sheet metal blank, wherein a wedge is cut out of each sheet metal blank and wherein the two edges of each wedge are brought together to form the concave trough and wherein each wedge ends with its tip at the intersection of the bends.
2. The fire bowl of claim 1 , wherein each segment is formed from a sheet metal, wherein a wedge is cut out of each sheet metal blank and wherein the two edges of each wedge are brought together to form the concave trough.
3. The fire bowl of claim 2 , wherein each sheet metal comprises a foot which is formed in one piece from the sheet metal blank.
4. The fire bowl of claim 3 , wherein each foot has a triangular form.
5. The fire bowl of claim 1 , characterized in that the feet are each designed as triangular-shaped folds of a sheet metal blank.
6. The fire bowl of claim 1 , wherein the connection of the segments to the fire bowl is provided at the feet.
7. The fire bowl of claim 1 , wherein for connecting the segments quick-release fasteners are provided at holes.
8. The fire bowl of claim 7 , wherein the quick-release fasteners are captively attached to the feet.
9. The fire bowl of claim 7 , wherein the quick-release fasteners are configured as bayonet or toggle fasteners.
10. The fire bowl of claim 1 , wherein fastenings for grilling accessories are provided on the fire bowl.
11. The fire bowl of claim 1 , wherein a grilling grate and/or a table top are provided on the fire bowl.
12. The fire bowl of claim 10 , wherein the fastenings are shaped as insertion openings on the respective segment.
13. The fire bowl of claim 1 , wherein the segments are positively clamped in the central area of the fire bowl.
14. The fire bowl of claim 13 , wherein the segments are positively clamped on a centering part with radial slots for engagement of lugs.
15. A method of manufacturing a fire bowl for the combustion of wood and similar fuels, wherein the fire bowl comprises a plurality of segments which are supported on the ground with feet and have a plurality of segment surfaces towards the top to form a trough-shaped fire bowl, wherein each segment surface of the fire bowl additionally has a concave trough, wherein the segment surfaces have intersecting bends for forming the troughs, and wherein each segment is formed from a sheet metal blank, and wherein the manufacture of each segment comprises bending a sheet metal blank several times along lines to form a stabilising trough after cutting the periphery on a bending machine, a wedge being cut out of the sheet metal blank so as to form a concave trough by bringing together the edges of the wedge, and wherein the wedge ends with its tip at the intersection of the bend.
16. The method of claim 15 , wherein the sheet metal blank is bent on the bending machine along lines for forming foot parts, the foot parts being bent through approximately 90° so that they each form a foot when the segments are assembled.
17. The method of claim 16 , wherein perforations and insertion openings are made in the sheet metal blank.
