Description

[0001] Cross - reference to related applications

[0002] This application claims the priority benefit of U.S. Provisional Application No. 63 / 384,571, entitled “Gas Adapter for a Wood - Burning Fire Pit,” filed on November 21, 2022. Background Art

[0003] This application relates to a gas adapter that is installed inside a wood - burning fire pit to convert the wood - burning fire pit into burning gas.

[0004] Various convertible fire pits are described in the prior - art patent literature. For example, US9038620 discloses a multi - faceted portable outdoor fireplace that can be converted into an open - air grill, a rotisserie grill assembly, and a smoker assembly. The fireplace includes a carriage assembly having a pair of rotatable wheels and at least one leg member; a chassis assembly for accommodating a solid - fuel heat source fixed to the carriage assembly; and a removable filter assembly located on top of the chassis assembly. When converted into an open - air grill, the fireplace further includes a grill bracket detachably attached to the filter assembly. In one embodiment, when converted into a smoker, the fireplace further includes at least one heat - insulating / wind - blocking panel that can be attached to the filter assembly; a smoker adapter body located on the filter assembly; an adjustable grate support frame and a lid fixed inside the smoker body.

[0005] However, the prior - art convertible fire pits do not provide a convenient means to alternately use wood as a fuel source and a gaseous fuel source such as propane or natural gas. Summary of the Invention

[0006] Accordingly, the present invention provides a way to use gas instead of wood for combustion in a wood - burning fire pit, so that a safer fire can be used when a wood - burning ban is in effect or in any other situation where gas is more convenient than wood.

[0007] According to one aspect of the present invention, a system for providing a gas burner adapter in a wood - burning fire pit is provided, including: a connector detachably connected to a burner, the connector being configured to pass through a narrow opening at the bottom of the wood - burning fire pit; and a connection member connected to a gas source.

[0032] Instant switching ability and fine control of the flame size;

[0033] In the current embodiment, the adapter does not require any modification to the wood-burning fire pit, and the wood-burning fire pit can still be used for burning wood (other wood-burning fire pits need to drill holes large enough to fit the connector without compromising the ability of the wood-burning fire pit to burn wood);

[0034] The adapter can be disassembled and flat-packed whether or not tools are used;

[0035] The adapter cools quickly;

[0036] The adapter is applicable to propane gas and natural gas, with or without an air mixer or valve;

[0037] The adapter can have or not have a plate, and can be used with or without lava (or other gas-enhancing accessories);

[0038] The adapter preserves the cooking ability of a fire pit that includes a cooking function; and

[0039] The adapter includes a locking quick-connect socket that is a connecting piece connected to a gas source.

[0048] Different embodiments of the wood-burning fire pit 6 can be any wood-burning fire pit having holes at its bottom for gas passage.

[0049] Different embodiments of the wood-burning fire pit 6 can be any wood-burning fire pit that needs to be modified to form an opening small enough for the connector 4 to fit without compromising the original ability of the fire pit to use wood.

[0050] Figure 12 All components of an embodiment of the gas adapter 1 and the connector connected to the gas source 5 are shown.

[0051] Although in the Figure 1 embodiment shown, two components are assembled to obtain the burner 2, the functional elements of the burner 2 can be assembled from components of more or less different shapes and, if necessary, can be integrally formed. In the depicted embodiment, the burner 2 consists of a square burner 7 and a plug 8.

[0052] Another embodiment can use a circular burner 2 or a burner of any shape. Another embodiment can combine the burner 2 and the plate 3 into one piece.

[0053] Although in the Figure 1 embodiment shown, four components are assembled to obtain the connector 4. However, the functional elements of the connector 4 can be assembled from components of more or less different shapes and, if necessary, can be integrally formed. In the depicted embodiment, the connector 4 consists of a quick-release fitting 12, a reducer fitting 11, an air mixer 10, and an extension fitting 9. This structure is designed to enhance the combustion of propane gas.

[0054] Different embodiments can omit the air mixer 10 for propane combustion and natural gas combustion.
