DETAILED DESCRIPTION

[0021] A first embodiment of the present concept includes a burner, a plate, a connector and a connection to a gas source. The burner and connector are assembled and fitted into a plate. These parts are then inserted into a wood fire pit. The assembly is then connected to a connection to a gas source, underneath the wood fire pit.

[0022] Another embodiment of the present concept includes a connection to a gas source connected to a hose, which is then connected to a gas source (with or without a regulator or valve).

[0023] (new paragraph) Another embodiment of the present concept includes an air mixer, assembled within the connector, for better gas combustion.

[0024] Another embodiment of the present concept excludes a plate.

[0025] Another embodiment of the present concept includes a set of lava rocks to improve flame dispersion, heat retention, heat radiation and overall campfire appeal.

[0026] Another embodiment of the present concept includes a burner of different shape, such as circular, octagonal, rectangular, triangular and so forth.

[0027] (new paragraph) Another embodiment of the present concept includes a quick release socket (available in locking and non-locking options) as a connection to a gas source.

[0028] The embodiment disclosed herein provides several advantages, the main advantage being to use gas for combustion instead of wood, which results in a safer fire that can be utilized where wood fire ban restrictions are in effect or any other situation where gas is more convenient than wood.

[0029] Additional advances include: [0030] no smoke; [0031] instantaneous on and off capability, along with fine control of flame size; [0032] in the current embodiment, the adapter does not require any modification to a wood fire pit, which can still be used for burning wood (other wood fire pits could require the drilling of a hole large enough to fit the connector without compromising the wood burning capability of the wood fire pit); [0033] the adapter can be disassembled, with or without tools, and pack flat; [0034] the adapter cools quickly; [0035] the adapter can be adapted to both propane and natural gases, with or without an air mixer or valve; [0036] the adapter can be used with or without a plate, with or without lava rocks (or other gas fire enhancing accessories); [0037] the adapter retains the ability to cook for fire pits that include such feature; and [0038] the adapter includes a locking quick-connect socket as a connection to a gas source.

[0039] For purposes of description herein the terms upper, lower, right, left, rear, front, vertical, horizontal, and derivatives thereof shall relate to the device as oriented in FIG. 1. However, it is to be understood that the device may assume various alternative orientations and step sequences, except where expressly specified to the contrary. It is also to be understood that the specific devices and processes illustrated in the attached drawings, and described in the following specification are simply exemplary embodiments of the inventive concepts defined in the appended claims. Hence, specific dimensions and other physical characteristics relating to the embodiments disclosed herein are not to be considered as limiting, unless the claims expressly state otherwise.

[0040] In the embodiment of a gas adapter 1 depicted in FIG. 1, a burner 2 is threaded onto a connector 4, which is then inserted through a plate 3. The assembly is then inserted into a wood fire pit 6, such as the one depicted in FIG. 6 and FIG. 7. The connector 4 fits through an opening at the bottom of the wood fire pit 6 as seen in FIG. 10 and FIG. 11. The connector 4 is then connected to a connection to a gas source 5 as depicted in FIG. 7. The connection to a gas source 5 is itself connected to a gas source by any means necessary.

[0041] Although shown as three parts that are assembled to form the adapter 1 in the embodiment depicted in FIG. 1, the functional elements of the adapter 1 may be constructed out of more or less assembled parts of different shapes, and maybe be integrally formed in a single piece, if desired. In the embodiment depicted, the adapter 1 is composed of a burner 2, a plate 3 and a connector 4. A different embodiment could omit the plate 3 for use with natural gas or for use without gas fire enhancing accessories. Plate 3 can also be of a different shape and serve the same purpose.

[0042] A different embodiment could use a quick release connection to attach the connector 4 to the burner 2 instead of a threaded connection.

[0043] FIGS. 2-5 illustrate one embodiment of the gas adapter 1 assembled and connected to a connection to a gas source 5 (in FIG. 4, the connection to a gas source 5 cannot be seen).

[0044] A different embodiment of the connection to a gas source 5 could be a threaded connection or a connection or any connection designed for use with gas.

[0045] FIG. 7 illustrates one embodiment of the gas adapter 1 assembled and lined up to be inserted into a wood fire pit 6, then connected to a connection to a gas source 5.

[0046] FIGS. 8-11 illustrate one embodiment of the gas adapter 1 assembled and installed into a wood fire pit 6, with a connection to a gas source 5 connected (only visible in FIG. 8).

[0047] A different embodiment of the wood fire pit 6 could be any wood fire pit which has a hole at its bottom that can be utilized for the passage of gas.

[0048] A different embodiment of the wood fire pit 6 could be any wood fire pit that would require a modification to create an opening small enough for a connector 4 to fit without compromising the original ability of the fire pit to use wood.

[0049] FIG. 12 illustrates all the components of an embodiment of the gas adapter 1 along with a connection to a gas source 5.

[0050] Although shown as two parts that are assembled to form a burner 2 in the embodiment depicted in FIG. 1, the functional elements of the burner 2 may be constructed out of more or less assembled parts of different shapes, and may be integrally formed in a single piece, if desired. In the embodiment depicted, the burner 2 is composed of a square burner 7 and a plug 8.

[0051] A different embodiment could use a round burner 2 or a burner of any shape. A different embodiment could combine the burner 2 and the plate 3 into one piece.

[0052] Although shown as four parts that are assembled to form the connector 4 in the embodiment depicted in FIG. 1, the functional elements of the connector 4 may be constructed out of more or less assembled parts, and may be integrally formed in a single piece, if desired. In the embodiment depicted, the connector 4 is composed of a quick release fitting 12, a reducer fitting 11, an air mixer 10, and a extender fitting 9. This configuration is designed to enhance combustion of propane gases.

[0053] A different embodiment could omit the air mixer 10 both for propane combustion and natural gas combustion.

[0054] FIGS. 13 and 14 illustrate the details and cross-section of an embodiment of the connector 4.
