Abstract

A wood-burning fire pit apparatus includes a bowl and an air flow member. The bowl defines an air flow opening and a wood-receiving opening adapted to support wood received in the wood-receiving opening. The air flow member extends from a lower region of a top surface of the bowl and toward an upper region of the top surface of the bowl. The air flow member defines a central bore in fluid communication with the air flow opening of the bowl. The air flow member defines one or more apertures therethrough in fluid communication with the central bore to enable air to travel into the air flow opening of the bowl and out of the one or more apertures of the air flow member into the wood-receiving opening of the bowl to facilitate burning of the wood received in the wood-receiving opening.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of U.S. Provisional Application Ser. No. 61/969,293, filed Mar. 24, 2014, the entirety of which is hereby incorporated by reference herein.

TECHNICAL FIELD

The present disclosure generally relates to fire pit apparatuses, and more particularly, to wood-burning fire pit apparatuses.

BACKGROUND

Fire pits have been around for many years and are designed to contain a fire and prevent it from spreading. Fire pits can be physically dug in the ground or may be prefabricated from materials such as stone, brick, and/or metal. In general, fire pits provide warmth and ambience to an outdoor venue such as a patio area and are typically designed to be fueled by either wood or propane cylinders. More specifically, wood-burning fire pit apparatuses include separate wood-supporting grates that are positioned on a bowl of the wood-burning fire pit apparatus a few inches above the base of the bowl to enable wood to be ignited and burned within the bowl. Due to the ability to remove the wood-supporting grates from the bowl, the grates are susceptible to being lost and/or misplaced. In addition, over time these wood-supporting grates can rust and/or otherwise become unusable from wear and tear requiring a user to buy replacement wood-supporting grates. The presently disclosed wood-burning fire pit apparatuses remedy some of the disadvantages of wood-burning fire pit apparatuses with wood-supporting grates.

SUMMARY

According to one aspect, a wood-burning fire pit apparatus includes a bowl and an air flow member coupled to the bowl to enable air to travel into the bowl through the air flow member to burn wood received in the bowl. The air flow member may be integrally formed with the bowl. In some embodiments, the air flow member is welded, or adapted to be welded, to the bowl. In certain embodiments, the air flow member is fastened, or adapted to be fastened, to the bowl.
The bowl has a top surface and a bottom surface. The top surface includes an upper region and a lower region and includes an inner portion that extends between the upper and lower regions of the top surface. The inner portion defines a wood-receiving opening and is adapted to support wood received in the wood-receiving opening. An air flow opening is defined between the lower region of the top surface of the bowl and the bottom surface of the bowl.
The air flow member extends from the lower region of the top surface of the bowl and toward the upper region of the top surface of the bowl. The air flow member defines a central bore in fluid communication with the air flow opening of the bowl. The air flow member defines at least one aperture therethrough. The at least one aperture is in fluid communication with the central bore to enable air to travel into the air flow opening of the bowl and out of the at least one aperture of the air flow member into the wood-receiving opening of the bowl to facilitate burning of the wood received in the wood-receiving opening.
In some embodiments, the at least one aperture of the air flow member is defined through the top wall. In embodiments, the at least one aperture of the air flow member is defined through the at least one sidewall. The air flow member can include a plurality of apertures. In some embodiments, at least one of the plurality of apertures is defined through the top wall of the air flow member and at least one of the plurality of apertures is defined through the at least one sidewall of the air flow member. The at least one aperture can extend through an upper terminal end of the air flow member.
The air flow member includes a top wall and at least one sidewall. The at least one sidewall includes an upper portion and a lower portion. The top wall is secured to the upper portion of the at least one sidewall and is disposed transverse to the at least one sidewall so that the top member and the at least one sidewall define the central bore. The lower portion of the at least one sidewall is secured to the lower region of the top surface of the bowl.
In embodiments, the lower portion of the at least one sidewall of the air flow member includes at least one flange extending outwardly from the at least one sidewall in a direction transverse to the at least one sidewall. The wood-burning fire pit can include at least one fastener. The at least one flange of the air flow member can define at least one first fastener opening therethrough. The bowl may define at least one second fastener opening. The at least one first fastener opening and the at least one second fastener opening are adapted to receive the at least one fastener to secure the air flow member to the bowl. In embodiments, the at least one fastener can be received in the at least one first fastener opening and the at least one second fastener opening to secure the air flow member to the bowl.
The bowl defines a longitudinal axis that extends through the top and bottom surfaces of the bowl. The air flow opening may be aligned with the longitudinal axis of the bowl. In embodiments, the air flow opening is centrally located on the bowl.
According to another aspect, the present disclosure relates to a wood-burning fire pit system including the bowl and the air flow member. The air flow member is adapted to secure to the lower region of the top surface of the bowl and has at least one sidewall and a top wall secured to the at least one side wall. The at least one sidewall and the top wall define a central bore. At least one of the top wall and the at least one sidewall define at least one aperture therethrough in fluid communication with the central bore, wherein securement of the air flow member to the bowl enables air to travel into the air flow opening of the bowl and out of the at least one aperture of the air flow member into the wood-receiving opening of the bowl to facilitate burning of the wood received in the wood-receiving opening.
According to yet another aspect, the present disclosure relates to a method for burning wood in a fire pit apparatus. The method includes positioning wood on a bowl of the fire pit apparatus about an air flow member extending from a top surface of the bowl into a wood-receiving opening of the bowl so that air can flow into the wood-receiving opening of the bowl through an upper terminal end of the air flow member and beneath the wood, and igniting a fire in the wood-receiving opening of the bowl to burn the wood directly on the top surface of bowl. When positioning the wood on the bowl, the method can involve arranging the wood to enable air to flow into the bowl through at least one sidewall of the air flow member.
Further details and aspects of exemplary embodiments of the present disclosure are described in more detail below with reference to the appended figures.
