The present invention relates to campfires. More particularly, the invention relates to a campfire support unit for burning firewood.
U.S. Pat. No. 5,722,390 to Hannebaum discloses a fireplace wood holder which holds firewood in a vertical position, so that the firewood's fibers and water-conducting channels are oriented substantially up and down, to allow more nearly complete burning and combustion. However, the fireplace holder provides only for wood that is enclosed by the holder. There is no mechanism for utilizing the holder to support firewood external of the holder. Although the applicant was, at the time he invented his campfire unit, not aware of the patent to Hannebaum, the present invention provides such a mechanism.
In general, the present invention provides a campfire support unit for burning firewood. The campfire support unit comprises (a) an annular member constructed and arranged to confine enclosed firewood, and to laterally support the enclosed firewood; (b) a plurality of lateral members extending outward from perimeter of the annular member, the lateral members being spaced apart, and being constructed and arranged to laterally support firewood disposed outside the perimeter of the annular member; and (c) support means for the annular member.
More specifically, reference is made to
The campfire support unit 2 comprises a rigid triangular annular member 3 constructed and arranged to confine and enclose firewood (not shown). The rigid triangular annular member 3 is supported by a plurality of legs 4, each leg 4 being connected to each apex 3a of the rigid triangular annular member 3. A pair of rigid tabs 5 extends outward from each apex of the perimeter 3b of the rigid triangular annular member 3. The tabs 5 are constructed and arranged to provide lateral support for firewood disposed outside the perimeter 3b of the rigid triangular annular member 3
The campfire support unit 2 is constructed and arranged to support wood for a wood fire in a near-vertical ring orientation around a central core of wood supported in a near-vertical orientation. The tabs 5 keep the near-vertical logs of the outer ring from falling during the fire-burning operation of the campfire support unit 2.
Any fire-resistant metal such as steel, or any non-metallic fire-resistant material capable of providing the necessary support for the firewood, could be used to fabricate the campfire support unit 2.
For operation, the campfire support unit 2 is placed in a location safe for burning firewood. A core fire is started with wood disposed within the rigid triangular annular member 3. Small, then medium-sized fuel wood is added to the core as the fire grows. Once the core fire is established, wood is added to and supported by the perimeter 3b and tabs 5. The core fire ignites the inside edges of the external wood ring. Once these inside edges are burning, larger logs can be added to the core. These larger logs will quickly reach ignition temperature and emit heavy flames. The vertical wood ring creates a draft that draws smoke and air into the core flame. This vertical draft generates more heat than a stacked fire, while also providing more flames from the wood. As the flames subside, more wood can be added to the core to generate continued flames from the fire. As the wood in the vertical ring burns down to coals, more vertical ring wood can be added to continue the process as along as desired.
Because of the controlled, substantially vertical configuration of the wood and the high core temperature during operation, the campfire support unit 2 burns wet or fresh-cut wood with less smoke than stacked fires. The campfire support unit 2 also develops a bed of coals more quickly than traditional campfire methods, thereby providing less time to start a cooking fire.
Reference is now made to
It will be apparent too those skilled in the art that, besides those disclosed herein, many other geometric shapes of the campfire unit are possible and feasible. Examples include a triangle that is not equilateral, and a rectangle that is not square.
While certain details and embodiments have been described to illustrate the principles of the present invention, it will be apparent to those skilled in the art that many modifications are possible within the scope of the claimed invention.
