Description

  The present invention relates to an assembly-type bonfire that is suitable mainly for cooking outdoors, can be disassembled and stored compactly during transportation, and can be easily assembled and installed during use.

  There are various types of bonfires for enjoying barbecue and other dishes outdoors at home, workplace, and regional recreation and camping. Since such a bonfire is not used permanently, it is generally compacted by a method such as folding when not in use and stored in a storeroom or the like.

  As an example of such a bonfire, Patent Document 1 discloses a bonfire that can be folded into a W shape. However, many of the commercial products, including the bonfire disclosed in Patent Document 1, are made of thin steel plates with a thickness of 1 mm or less and use hinges to make them foldable. Even if it is not folded, it is actually a situation that requires considerable storage space.

  In this kind of bonfire, it is common usage to bake ingredients such as meat, fish and vegetables by placing a wire mesh on the bonfire or arranging metal bars. It is not always suitable to use a heavy cooker such as a hot pot or an electric kettle. In addition, due to the above-described vulnerability, when a heavy solid fuel is used, the bonfire may be deformed. For this reason, when using a pan or kettle, or using heavy solid fuel, dig a hole in the ground, assemble stones of an appropriate size to form a flame bed, or install a stationary type furnace. It is necessary to use it.
