This disclosure relates to outdoor combustion devices in general and, more specifically, to outdoor solid fuel fire pits.
Various outdoor fire pits utilize particular arrangements of air inlets and air flow configurations to improve light output or flame appearance while reducing smoke and undesirable wind effects. In some cases, outdoor fire pits may be configured to take air in through the exterior of the fire pit and then deliver it in a particular way to an interior where combustion of solid fuel occurs. This means that users may be unable to install a fire pit into a permanent structure, or even certain decorative structures, without either being limited in the design of such structure (e.g., being required to provide for additional external ventilation ports) or diminishing the performance of the fire pit.
What is needed is a system and method for address the above and related considerations.
The invention of the present disclosure, in one aspect thereof, comprises a fire pit insert ring for use with a fire pit installation. The fire pit ring includes a surround defining an opening sized to accept a fire pit, and a vent panel attached to the surround and defining a plurality of vent openings. The vent panel provide airflow into the installation and to an outer wall of the firepit.
The opening defined by the surround may be sized to pass at least a portion of the outer wall of the firepit therethrough and to suspend the firepit in the installation by a rim of an upper cover of the fire pit. The vent panel may descend below the surround. A circumference of the vent panel may be sized to rest on an upper ledge of the installation and provide air flow below the surround and inwardly toward the outer wall of the firepit. The surround may slope downwardly away from the upper cover of the fire pit. In some cases, the vent panel slopes downwardly from the surround at an angle exceeding a downward sloping angle of the surround. The downward sloping angle of the surround may be approximately equal to a downward sloping angle of the upper cover of the fire pit.
The invention of the present disclosure, in another aspect thereof, comprises a fire pit insert ring for use with a fire pit installation. The insert ring includes surround having a panel spanning a distance between a firepit and an upper ledge of the installation suspending the fire pit partially inside the installation. The panel has at least one support ledge in contact with the fire pit and at least one rebated portion spaced apart from the firepit such that air flow is provided between the rebated portion and the firepit allowing air flow into the installation.
The panel may be divided into segments, each segment having a support ledge on both opposite ends thereof and a rebated portion on a medial portion thereof. The segments may join together to define a circular opening accepting the fire pit. In some embodiments, the support ledges of each segment face inwardly and support the fire pit in a suspended fashion via a rim on an upper cover of the fire pit. The panels have a downward slope away from the fire pit that approximately equates to a downward slope of the upper cover of the fire pit.
The invention of the present disclosure, in another aspect thereof, comprises a fire pit installation including a support structure having a support wall defining an opening on a top thereof and an upper ledge surrounding the opening and a fire pit having an outer wall with an air intake defined therein, an inner wall defining a combustion chamber, and an upper cover spanning between the outer wall and the inner wall, the upper cover providing a rim protruding outwardly from the outer wall. The installation includes an insert ring that suspends the fire pit by the rim at least partially within the opening of the support structure, the insert ring providing ventilation into the support structure to the outer wall of the fire pit.
In some embodiments, the insert ring has a surround defining an opening receiving the fire pit and a vent panel descending from the surround to contact the upper ledge of the support structure. The surround may define a circular opening. In some cases, the vent panel descends approximately vertically from the surround. The surround may slope outwardly down from the fire pit.
In other embodiments, the insert ring defines a circular opening and provides a plurality of inwardly projecting support ledges that engage the rim of the fire pit. The insert ring may define a plurality of rebated portions spaced apart from the fire pit providing the ventilation into the support structure. The insert ring may be divided into a plurality of separable segments each having at least one of the plurality of support ledges and at least one of the plurality of rebated portions.

As shown, the firepit 100 has a top cover 110 spanning what would otherwise be an open space between walls 104, 106. An outer rim 112 is provided that may overhang the wall 104 by a sufficient amount that the fire pit 100 may be lifted or elevated thereby as discussed further below. The fire pit 100 may sit on a base 108 or may be provided with a stand for elevating the fire pit 100 to a more desirable height and/or reduce the chance of scorching grass or other material near the fire pit 100. Various ash handling mechanisms may also be provided.
It should be appreciated that in some embodiments the exact configuration of a fire pit suitable for use with embodiments of the fire pit ventilation ring may vary. While there may be particular advantages to a system employing a fire pit as described herein, any fire pit benefiting from or requiring external air flow may realize increased utility in terms of installation options utilizing fire pit ventilation rings and other aspects of the present disclosure. Additionally, while embodiments of the present disclosure are described as relying on the outer rim 112 for suspending the firepit, other implements of a particular fire pit may be utilized in this regard. For example, specific mounting brackets, handles, or other protrusion may serve to good effect for allowing a fire pit to be affixed to or suspended by various ventilation rings according to the present disclosure.

The number of openings 206 may vary. In some embodiments, the openings 206 are present on half or more of the circumference of the vent panel. In various embodiments, the openings 206 may be oblong, circular, square, rectangular, or have other shapes. Additionally, not all openings 206 are necessarily identically shaped. Ventilation may also be provided on the surround 202. As illustrated, the masonry installation 220 comprises a cylindrical wall 224 with a circular open top 226 surrounded by a circular top or ledge 228. The ventilation insert ring 200 may rest on or be affixed to the ledge 228 and interpose the fire pit 100 and the masonry wall 224. When installed, the fire pit 100 may be spaced apart from the wall 224 sufficiently that air can flow into the fire pit wall 104 by entering the vent openings 206 and travelling downward into the opening 226 of the masonry installation 220.

The masonry installation 220 is intended to be exemplary and serves as a stand, or support structure. Any structure capable of supporting the fire pit's 100 size and weight could be utilized along with the fire pit ventilation ring insert 200 or others according to the present disclosure. Such installation structure could comprise brick, concrete, treated wood, wrought iron, or other materials. Whether the installation structure provides ventilation, is air permeable, or sealed, the fire pit ventilation insert ring 200 ensures that adequate combustion air flow is provided to the fire pit 100 under most or all conditions to allow the fire pit 100 to function as intended with combustion air entering through the walls rather than primarily through the top, which can lead to excessive smoking and other issues.

Each segment 402 comprises a panel 404 with a rebated or recessed portion 406. The rebated portion 406 is spaced apart from the top cover 110 of the fire pit 100 when the insert ring 400 is installed. On opposite ends 408 of the panel 404 are support ledges 410 that receive the rim 112 of the firepit 100 when installed. Thus, the firepit 100 is supported but the rebated portions 406 are spaced apart from the firepit 100, the top cover 110, and the rim 112 to define ventilation openings 502.
As there are three segments 402, a mechanism may be provided for joining the segments together to complete the insert ring 400. As shown, the opposed ends 408 are configured to receive connectors 412 where one segment 402 joins to the other. The ends 408 may be folded similar to a rail joiner such that the connector 412 is retained by each end 408 in a friction fit. The connector 412 may comprise planar piece of material allowing the ends 408 to join together in a flush manner as shown in

It is to be understood that the terms “including”, “comprising”, “consisting” and grammatical variants thereof do not preclude the addition of one or more components, features, steps, or integers or groups thereof and that the terms are to be construed as specifying components, features, steps or integers.
If the specification or claims refer to “an additional” element, that does not preclude there being more than one of the additional element.
It is to be understood that where the claims or specification refer to “a” or “an” element, such reference is not be construed that there is only one of that element.
It is to be understood that where the specification states that a component, feature, structure, or characteristic “may”, “might”, “can” or “could” be included, that particular component, feature, structure, or characteristic is not required to be included.
Where applicable, although state diagrams, flow diagrams or both may be used to describe embodiments, the invention is not limited to those diagrams or to the corresponding descriptions. For example, flow need not move through each illustrated box or state, or in exactly the same order as illustrated and described.
Methods of the present invention may be implemented by performing or completing manually, automatically, or a combination thereof, selected steps or tasks.
The term “method” may refer to manners, means, techniques and procedures for accomplishing a given task including, but not limited to, those manners, means, techniques and procedures either known to, or readily developed from known manners, means, techniques and procedures by practitioners of the art to which the invention belongs.
The term “at least” followed by a number is used herein to denote the start of a range beginning with that number (which may be a ranger having an upper limit or no upper limit, depending on the variable being defined). For example, “at least 1” means 1 or more than 1. The term “at most” followed by a number is used herein to denote the end of a range ending with that number (which may be a range having 1 or 0 as its lower limit, or a range having no lower limit, depending upon the variable being defined). For example, “at most 4” means 4 or less than 4, and “at most 40%” means 40% or less than 40%.
When, in this document, a range is given as “(a first number) to (a second number)” or “(a first number)−(a second number)”, this means a range whose lower limit is the first number and whose upper limit is the second number. For example, 25 to 100 should be interpreted to mean a range whose lower limit is 25 and whose upper limit is 100. Additionally, it should be noted that where a range is given, every possible subrange or interval within that range is also specifically intended unless the context indicates to the contrary. For example, if the specification indicates a range of 25 to 100 such range is also intended to include subranges such as 26-100, 27-100, etc., 25-99, 25-98, etc., as well as any other possible combination of lower and upper values within the stated range, e.g., 33-47, 60-97, 41-45, 28-96, etc. Note that integer range values have been used in this paragraph for purposes of illustration only and decimal and fractional values (e.g., 46.7-91.3) should also be understood to be intended as possible subrange endpoints unless specifically excluded.
It should be noted that where reference is made herein to a method comprising two or more defined steps, the defined steps can be carried out in any order or simultaneously (except where context excludes that possibility), and the method can also include one or more other steps which are carried out before any of the defined steps, between two of the defined steps, or after all of the defined steps (except where context excludes that possibility).
Further, it should be noted that terms of approximation (e.g., “about”, “substantially”, “approximately”, etc.) are to be interpreted according to their ordinary and customary meanings as used in the associated art unless indicated otherwise herein. Absent a specific definition within this disclosure, and absent ordinary and customary usage in the associated art, such terms should be interpreted to be plus or minus 10% of the base value.
Thus, the present invention is well adapted to carry out the objects and attain the ends and advantages mentioned above as well as those inherent therein. While the inventive device has been described and illustrated herein by reference to certain preferred embodiments in relation to the drawings attached thereto, various changes and further modifications, apart from those shown or suggested herein, may be made therein by those of ordinary skill in the art, without departing from the spirit of the inventive concept the scope of which is to be determined by the following claims.
This application is a continuation-in-part of U.S. patent application Ser. No. 17/339,670 entitled FIRE PIT VENTILATION INSERT RING filed on Jun. 4, 2021, the contents of which are hereby incorporated by reference.
