The outer sleeve 102, inner sleeve 104, gridiron 106, baseplate 108, and the subparts of each, are all substantially described below in relation to FIG. 1B-2.
FIG. 1B is a second elevational perspective view of a free-standing, portable, multi-function fire pit 100 in accordance with the present invention. The fire pit 100 comprises five principal modules/sections: an outer sleeve 102, an inner sleeve 104, a gridiron 106, and a baseplate 108. The outer sleeve 102 comprises an upper rim 109, engraved text 110, and outer legs 112 a-c. The inner sleeve 104 comprises grating 116 and leaves 118 a-c. The baseplate 108 comprises aperatures 120 a-d and inner legs 122 a-b.
The present invention is adapted to be easily assembled and disassembled.
The outer sleeve 102 comprises an elongated, tubular metallic member formed of material capable of withstanding temperatures of at least 240 degrees Fahrenheit, such as iron or steel. The outer sleeve 192 comprises an upper rim 109 and a lower rim. A longitudinal axis extends throughout the length of the outer sleeve. When the other sleeve sits upright surrounding the baseplate, the longitudinal axis extends from center of the baseplate 108 in an upwardly direction through the center of the outer sleeve 102.
The outer sleeve 102 comprises an engraved textual design 110, or engraved text 110, which in some embodiments, might include registered trademarks (e.g. either word marks or stylized marks) of universities, commercial enterprises, non-profit organizations, individuals, or even flags of countries, and the like. In other embodiments, the engraved text 110 consists of a logo. In some embodiments, the engraved text 110 may be protuberant with respect to the outer sleeve 102 (e.g. the text itself may be defined by protuberances on the outer shell).
The fire pit 100 is thus “themed,” in that the fire pit 100 may be exclusively associated with a particular theme, such as a university, company, country and the like. The outer sleeve 102 may be color coordinated with the trademark reflected in the engraved text 110, such as color coordinated with the colors of a university or high school.
The outer sleeve 102, in the shown embodiment, is disposed around the baseplate 108 in its fully assembled configuration such that the outer sleeve 102 rests on the ground. The present invention is configured in its fire pit configuration by sliding the outer sleeve 102 over and around the baseplate 108 when the baseplate 108 is resting on the ground.
In some embodiments, the outer sleeve 102 and/or the inner sleeve 104 are square across their cross-sections from a top-perspective. In other embodiments, the outer sleeve 102 and/or the inner sleeve 104 are triangular, rectangular, octagonal, or polygonal (or any combination of the above) from a cross-sectioned top-perspective view.
The inner sleeve 104 comprises a semi-enclosed receptacle for housing burning fuel. The inner sleeve 104 is detachably connectable at its base to the baseplate 108. Like the outer sleeve 102, the inner sleeve 104 comprises an elongated, generally cylindrical metallic member with a top inner rim and a bottom inner rim. The inner sleeve 104, however, is grated as shown such that the inner sleeve 104 only partially encloses a fire lit within it. The bottom inner rim is detachably affixed to the baseplate 108 in the shown embodiment, but may be detachably affixed to a briquette collar in other embodiments.
The grating of the inner sleeve 104 comprises a plurality of horizontal and vertical bars, which cross and/or overlap and/or interlock and/or intersect. In some embodiments of the inner sleeve 104, the grating may be helical, in that its horizontal bars circle and define the inner sleeve 104 helically. In other embodiments, the grating may comprise irregular or repeating patterns of various kinds known to those of skill in the art. In still further embodiments, the inner sleeve 104 may comprises stiff wire, bars running vertically without horizontal counterparts, or even chicken wire.

The leaves 118 a-c curve, in the shown embodiment, with the curve of the inner sleeve 104 which axially surrounds the longitudinal axis.
In some embodiments of the present invention, the diameter of the inner sleeve 104 is predetermined to exceed the diameter of a tank of propane or other fuel source housed within the inner sleeve 104.
The height of the inner sleeve 104 may be adjustable. The inner sleeve 104 may be telescopic. In some embodiments, the inner shell 104 may comprise one or two flanges disposed on the top or bottom of the inner shell 104, or disposed alongside the inner shell 104. The flanges may serve as grips for lifting the inner sleeve 104 or supporting the gridiron 106.
The gridiron 106 is circular in the shown embodiment, and disposed above the inner sleeve on the top inner rim for barbequing food. The gridiron 106, or grill, is well known to those of skill in the art, and may comprise any number of two-dimensional geometric shapes, including square, rectangular, triangular, octagonal, and the like.
The baseplate 108 comprises a metallic disk of a diameter larger than the diameter of the inner sleeve. The metallic disk comprises a plurality of aperatures, slots, grooves, notches, ruts, or the like, for receiving either the leaves 118 a-c of the inner sleeve 104 or substantially similar leaves of a briquette collar. The leaves 118 a-c may interlock with the baseplate 108. The metallic disk of the baseplate 108 is oriented orthogonally to the longitudinal axis.
In some embodiments, the baseplate 108 is manufactured from stone, petrified wood, or heat-resistant polymers. The fire pit 100 is designed such that each of its four sections are independently replaceable if destroyed, damaged, or worn out.
The baseplate 108 comprises a plurality of inner legs 122 a-c disposed below the metallic disk for engaging the ground.
The inner legs 122 a-b comprise ground-engaging components. In some embodiments, the inner legs 122 a-b may be skirted, or may jut outward for increased stability of the fire pit 100.
The upper rim 109 may be notched. The upper rim 109 of the outer shell 102 may also be knurled to provide grip to a user needing to slide the outer shell axially such that the outer shell falls into place, or to provide grip for fire pit 100 accessories.
