Description
CROSS-REFERENCE TO RELATED APPLICATION
[0001] This application claims priority from U.S. Provisional
Application Ser. No. 61/437,064, filed Jan. 28, 2011, the
disclosure of which is incorporated herein by reference.
BACKGROUND OF THE INVENTION
[0002] 1. Technical Field
[0003] The present invention relates generally to fire pits. More
particularly, the present invention relates to an outdoor backyard
fire pit configured to receive fuel blocks having a particular
shape. Specifically, the present invention relates to such a fire
pit which is configured to receive and hold fuel blocks in a
desired placement around a vent opening to allow an efficient
burning of the fuel.
[0004] 2. Background Information
[0005] The general concept of a fire pit can physically vary from a
pit dug into the ground to an elaborate gas burning compilation of
stone, brick, and metal. The common feature of fire pits is that
they are designed to contain a fire and prevent it from spreading.
Pre-made fire pits are the most common form of fire pits and
typically mass-produced and purchased from a store. These are made
mostly of metal and can be either wood or gas burning. Unlike
traditional fire pits, these fire pits are portable and may contain
a screen or cover to prevent cinders or floating ash from escaping
and starting a fire outside the pit.
[0006] Heretofore, wood burning manufactured fire pits have all
suffered from the same inefficiencies. Namely, the placement of
wood or fuel is typically haphazard and therefore the space inside
the fire pit is not fully utilized, and the fuel itself burns
inefficiency. Furthermore, many fire pits do not include
ventilation beyond a simple bowl-like structure which only allows
air to be supplied from above the fire. Therefore, there is a great
need in the art not only to use the available pit space more
efficiently, but to burn the fuel more efficiently as well.
BRIEF SUMMARY OF THE INVENTION
[0007] The present invention provides a fire pit to be used in
conjunction with particularly sized fuel blocks, and align these
fuel blocks in a square-shaped configuration around ventilation
holes provided through the base of the fire pit. The base is formed
from a plate having a plurality of alignment flanges extending
upwardly therefrom. The alignment flanges provide a positioning and
alignment brace for the fuel blocks, which are fitted into an
abutting relationship with the alignment flanges and one another
while on the plate. After the first layer of fuel blocks is formed,
multiple horizontal layers of fuel blocks may be disposed on one
another to provide a sufficient vertical length of fuel for a fire.
It is a primary feature of the invention that the ventilation holes
are disposed generally in the center of the base and align with an
inner chimney or air shaft formed by the positioning of the fuel
blocks. This chimney or air shaft is formed by the fuel blocks over
the ventilation holes to allow the fire to burn from the chimney
outwardly through the blocks and thereby provide an efficient
burning of the fuel.

DETAILED DESCRIPTION OF THE INVENTION
[0021] The portable fire pit system of the present invention is
shown in FIGS. 1-11 and is indicated generally at 1. As shown in
FIGS. 1 and 2, fire pit system 1 includes a fire pit 2 which
extends generally from an upper end 3 to a lower end 5 and includes
a lid 7, a spark guard 9, and a base 11. Lid 7 includes a wire mesh
portion 13 which defines a plurality of openings 14 and extends
from an annular ring 15. Annular ring 15 is sized to removably and
snuggly fit around an annular ring 17 having a slightly smaller
diameter and disposed on spark guard 9. Spark guard 9 further
includes a wire mesh portion 19 extending from annular ring 17 to a
lower end 21, and is formed in a generally cylindrical overall
shape. Wire mesh portion 19 defines a plurality of openings 20 for
allowing air to pass therethrough and to prevent cinders or
floating ash from escaping and starting a fire outside the pit.
[0022] Referring to FIGS. 1-3, base 11 includes a plate 23 having
an upper surface 22, a lower surface 24 (FIG. 7), an annular ring
25 extending outwardly from upper surface 22 and around the
periphery of plate 23. Base 11 further includes a pit area 18
defined by upper surface 22 and annular ring 25, and plurality of
legs 27, shown as three legs 27, extending outwardly from lower
surface 24 and in the opposite direction from annular ring 25. A
plurality of air flow apertures 29 are defined by plate 23 and
disposed generally proximate the diametrical center of plate
23.
[0023] As shown in FIGS. 2 and 3, a plurality of alignment flanges
31 extend outwardly and generally perpendicularly from upper
surface 22. Flanges 31 are arranged to define a generally
square-shaped (FIG. 3) fuel containment area 33 within pit area 18
and having apertures 29 disposed proximate the center of the
square. Each flange 31 is a straight, flat, rectangular-shaped
fin-like structure which includes an inner surface 35, whereby each
inner surface 35 faces towards apertures 29. As shown in FIGS. 4
and 5, flanges 31 are sized and positioned to align a plurality of
fuel blocks 37 in a particular horizontal and vertical alignment
around apertures 29, thereby defining an air shaft or chimney 39
extending from apertures 29 through fuel blocks 37. Common
atmospheric air is intended to flow up through apertures 29,
through chimney 39, and outwardly away from the top layer of blocks
37. Thus, a fire 41 (FIG. 7) ignited inside chimney 39 will burn
through fuel blocks 37 efficiently from chimney 39 outwardly
through blocks 37, due to the proper airflow ensured by apertures
29 and chimney 39.
[0024] Fuel blocks 37 may be comprised of any ignitable substance
commonly used with fire pits, including highly compacted sawdust,
which may be free of chemical binders or other additives. As shown
in FIG. 4, fuel blocks 37 are formed in a hexahedron or cuboid
shape with six generally flat sides which extend generally at 90
degree angles to one another to form a block shape. Each fuel block
37 includes a generally similar length L and a generally similar
width W. As discussed above, four fuel blocks 37 are arranged
around apertures 29 disposed in plate 23 to form chimney 39. The
block-like nature of fuel blocks 37 facilitate such a
configuration, and further allow stacking of multiple layers of
blocks.
[0025] With primary reference to FIGS. 4 and 5, the positioning and
relative placement of blocks 37 is described in greater detail,
with specific reference to blocks 37A and 37B. Each block 37
includes a top side 70, a bottom side 72, a right side 74, a left
side 76, a rear side 78, and a front side 80, corresponding to the
six sides of the hexahedron shape of blocks 37. Right side 74 and
left side 76 are of length L, while front side 80 and rear side 78
are of width W. Top sides 70 and bottom sides 72 extend generally
horizontally when properly positioned in fire pit 2, and right side
74, left side 76, rear side 78, and front side 80 extend generally
vertically. To achieve the specific configuration of blocks 37
which forms chimney 39 around apertures 29, each of the four blocks
37 are placed on base 11 whereby bottom side 72 is adjacent upper
surface 22, such that right side 74 of each block 37 abuts a
corresponding alignment flange 31, and each rear side 78 abuts
another corresponding alignment flange 31. This braces and holds
blocks 37 in place on two of the four vertically extending sides.
The other two vertically extending sides are braced and held by
positioning front side 80 of each block 37 such that front side 80
abuts left side 76 of an adjacent block 37, thereby bracing the
other two of the four vertically extending sides. As shown in FIG.
4, front side 80 of block 37B abuts left side 76 of block 37A. It
will be readily understood from the above description and with
reference to FIG. 5 that inasmuch as five of the six sides of
blocks 37 are firmly abutting adjacent elements, blocks 37 are
firmly positioned and held in place on plate 23. Once positioned in
this manner, blocks 37 may generally only be moved in the
vertically upward direction. As such, blocks 37 are firmly secured
in a "puzzle-like" configuration which defines chimney 39 over
apertures 29. As shown in FIG. 4, in order to achieve this specific
configuration and alignment of fuel blocks 37 on plate 23, each
parallel alignment flange 31 is spaced a distance X apart, where X
is generally equal to length L plus width W of fuel blocks 37.
Thus, each parallel alignment flange 31 can receive the length L of
a fuel block 37 and the width W of a fuel block 37
therebetween.
[0026] As shown in FIG. 5, a first layer 38 is formed and disposed
directly on plate 23 and thereafter a second layer 40 is formed and
disposed directly on first layer 38. Top sides 70 of blocks 37 in
first layer 38 abut bottom sides 72 of block 37 in second layer 40.
As shown in FIG. 6, first layer 38 and second layer 40 are formed
in a general cross-sectional square shape with a void in the center
of the square which allows air to flow through apertures 29. This
allows an efficient stacking of fuel with no wasted space disposed
therein, which fully utilizes fuel containment area 33. As such,
air flows upwards through plate 23 and through chimney 39 formed by
fuel blocks 37, thereby providing a long, even output of heat
energy as fire 41 burns from chimney 39 outward through fuel blocks
37 and towards flanges 31. As a result of the efficient burning of
fuel blocks 37, the overall size of portable fire pit 2 may be
dramatically reduced, as less fuel is needed to produce generally
the same amount of heat energy as a traditional fire pit. This
reduction in the overall size of fire pit 2 allows for the
reduction in material costs and shipping costs, and allows for
increased portability of the device.
[0027] As shown in FIGS. 5-7, flanges 31 are arranged to align
first layer 38 of fuel blocks 37 around apertures 29. Each side of
the square is braced by flanges 31, which are disposed in pairs
around the periphery of the square. As shown particularly in FIG.
7, flanges 31 extend generally at a 90 degree angle with respect to
upper surface 22 of plate 23, thereby forming a complementary
structure to receive the 90 degree angled sides of fuel blocks 37
therein.
[0028] In addition to aligning fuel blocks 37, flanges 31 further
provide bracing support to each fuel block 37 disposed in first
layer 38. As fuel blocks 37 in first layer 38 burn, the material
breaks down and may shift without proper support. Inasmuch as first
layer 38 provides a base upon which to build second layer 40, if
first layer 38 shifts or moves, second layer 40 may collapse and
thereby close off or partially block chimney 39. Therefore, even as
fuel blocks 37 in first layer 38 burn, blocks 37 maintain their
position due to flanges 31. Furthermore, fuel blocks 37 are
reinforced and braced by one another, as each block 37 abuts two
other blocks 37, as can be seen in FIG. 5. The abutting
relationships between adjacent blocks 37, as well as the abutting
relationships between blocks 37 and alignment flanges 31 thereby
ensure chimney 39 remains intact throughout the burning process. As
such, it is one of the primary features of the invention that each
fuel block 37 is abutting or adjacent to at least one flange 31,
and each fuel block 37 is vertically abutting or adjacent to two
other fuel blocks 37.
[0029] As shown in FIG. 8, fire pit 2 may also include a hook
device 59 engagable with an elongated nut 65 as a means for locking
lid 7 and spark guard 9 to base 11. Hook device 59 includes a
hooked end 61 and a spaced apart threaded end 63, with a shaft 60
extending therebetween. Hooked end 61 is formed to engage openings
14 of wire mesh portion 13 of lid 7 whereby shaft 60 is positioned
to extend towards base 11. Threaded end 63 of hook device 59
thereby extends through one of apertures 29 and outwardly from
lower surface 24 of plate 23. Elongated nut 65 includes an opening
67 defined by a threaded surface 69 configured to engage threaded
end 63 and hold it securely therein. Elongated nut 65 is formed in
a slightly concaved shape extending from a first end 71 to a second
end 73, whereby opening 67 is defined proximate first end 71. As
shown in FIG. 8, when first end 71 is secured to hook device 59,
second end 73 is thereby positioned to press against lower surface
24 of plate 23, which braces hook device 59 and in turn holds lid 7
and spark guard 9 securely to base 11. As elongated nut 65 is
turned in the direction of Arrow C, threaded surface 69 guides nut
65 along shaft 60, which draws second end 73 closer to lower
surface 24. Once nut 65 is sufficiently threaded upwards on shaft
60, second end 73 firmly abuts lower surface 24 and holds hook
device 59 in position. To remove elongated nut 65, a user simply
turns nut 65 in the direction of Arrow B to unscrew nut 65 off
shaft 60 and thereby release hook device 59. When elongated nut 65
is released from threaded end 63, hook device 59 may thereby be
removed from engagement with openings 14 of wire mesh portion 13 of
lid 7.
[0030] Inasmuch as fire 41 burns directly under lid 7 during use of
portable fire pit system 1, lid 7 may become extremely hot and
untouchable to the user. However, as fuel blocks 37 burn away and
need replaced or moved, a user may wish to access pit area 18.
Therefore it is desirable to remove lid 7, yet lid 7 may be
extremely hot. In addition to locking lid 7 on base 11, hook device
59 may be also used to remove lid 7 from spark guard 9 when the
user wishes to manipulate fuel blocks 37. Hook end 61 of hook
device 59 is extended into one of openings 14 of wire mesh portion
13 and used as a gaff to pull lid 7 off of spark guard 9. The user
holds generally the area around threaded end 63 of hook device 59,
which allows the shaft 60 and hook end 61 to move close to the
flames of fire 41 during removal of lid 7, while keeping the user's
hand a safe distance away from the heat.
[0031] As shown in FIG. 10, fire pit 2 may also include a grill
system 42, which includes a positioning rod 45 and a grill 49.
Positioning rod 45 is a rod shaped cylindrical beam which extends
from an upper end 46 to a spaced apart lower end 47. Grill 49
includes a screen 51 disposed on an arm 53, whereby the arm extends
from a connection bracket 55 having a rod aperture 57. Grill system
42 further includes a peg 43 disposed on base 11 and extending
outwardly away from upper surface 22 of plate 23. Peg 43 is sized
to be received in an opening (not shown) disposed proximate lower
end 47 of positioning rod 45. An upper end 46 of positioning rod 45
is sized to be received in rod aperture 57 of bracket 55, whereby
screen 51 is positioned at a particular level above plate 23
extending generally parallel with upper surface 22 of plate 23.
Bracket 55 is shown frictionally engaging positioning rod 45 by way
of rod aperture 57 to maintain the desired distance between plate
23 and screen 51. However, the present invention encompasses any
means common in the art which may be used to engage grill 49 with
rod 45.
[0032] As shown in FIGS. 9 and 11, grill 49 is pivotable about
positioning rod 45 by way of connection bracket 55. Grill 49
maintains the same general plane during this pivoting operation.
Grill 49 is movable within this plane to selectively expose food
(not shown) placed on screen 51 to fire 41 as well as remove it as
desired.
[0033] As shown in FIG. 11, grill 49 is movable between a first
position, shown in solid lines, and a second position, shown in
phantom. As positioning rod 45 has a generally circular
cross-sectional shape, grill 49 may pivot in the direction of
Arrows D or E to move grill between the first and second position,
and any intermediate position therebetween and desired. In addition
to the pivotable nature of grill 49, as the connection between rod
aperture 57 of connection bracket 55 and positioning rod 45 is a
simple frictional engagement, grill 49 may be placed at any
horizontal position along rod 45 as desired by the user. This
allows the user more control over how much heat from fire 41
reaches food placed on screen 51. Therefore, as discussed above,
grill system 42 is adjustable in both the horizontal and vertical
directions to provide the user maximum control over the cooking
operation.
[0034] In operation, a user typically transports or stores fire pit
system 1 in a locked state, whereby lid 7 is locked to base 11 by
way of hook device 59. Hook end 61 of hook device 59 extends
through one opening 14 of wire mesh portion 13 with shaft 60
extending through another opening 14 and downwardly through one
aperture 29 of plate 23, thereby locking hook end 61 onto wire mesh
portion 13.
[0035] Located proximate threaded end 63, elongated nut 65 is
removed by manually unscrewing elongated nut 65 in the direction of
Arrow B (FIG. 8). After elongated nut 65 is removed from threaded
end 63, the user simply removes hook device 59 from fire pit 2
thereby releasing lid 7 from base 11. The user then manually
removes lid 7 which exposes pit area 18 and fuel containment area
33. The fuel blocks 37 may be transported inside fire pit 2 for
convenience. The user places fuel blocks 37 within fuel containment
area 33 in an abutting relationship with at least one alignment
flange 31 as well as two vertically adjacent fuel blocks 37, as
shown in FIG. 5, to form a generally square-shaped cross sectional
configuration. First layer 38 is disposed on upper surface 22 of
plate 23 and thereafter second layer 40 is disposed on top side 70
of each block 37 in first layer 38, thus defining chimney 39
therein (FIG. 6). As shown particularly in FIG. 7, fire 41 is
formed by the user within chimney 39 and efficiently supplied with
common atmospheric air through apertures 29, whereby air enters
chimney 39 through apertures 29 in the direction of Arrow A. Thus,
fire 41 burns efficiently from chimney 39 outwardly through fuel
blocks 37 in the direction of alignment flanges 31. As such, the
entirety of fuel blocks 37 is consumed by fire 41.
[0036] After fire 41 is burning within chimney 39, a user may wish
to remove lid 7 from annular ring 17 of spark guard 9, or
alternatively, a user may wish to place lid 7 on annular ring 17.
However, due to fire 41 burning and releasing heat upwardly from
pit 18, the area where lid 7 resides on annular ring 17 as well as
lid 7 itself may be extremely hot. Therefore, hook device 59 may be
used to remove lid 7.
[0037] Hook end 61 is extended into lid 7 through openings 14 of
wire mesh portion 13 to hook lid 7 thereby allowing the user to
remove lid 7 without physically touching the hot portion.
[0038] Referring particularly to FIGS. 9-11, while lid 7 is removed
from base 11, a user may wish to use grill system 42 to grill
various food items. As such, lower end 47 of positioning rod 45 is
lowered into the inner area of spark guard 9 towards base 11 and
connected therewith through peg 43. Grill 49 is then connected with
upper end 46 of positioning rod 45 through rod aperture 57 of
connection bracket 55 disposed on grill 49. As shown in FIG. 11, a
user may then swing grill 49 outwardly away from spark guard 9 to
place the food items onto grill 49 without the hot flames of fire
41 burning underneath. After food is placed thereon, grill 49 is
then rotated in the direction of Arrows D or E to dispose the food
and grill 49 over flames of fire 41. It will be readily understood
that heat from fire 41 cooks the various food items disposed on
grill 49. When the food is sufficiently cooked, grill 49 is then
rotated in the direction of Arrows D or E to remove food from
flames of fire 41. Thus, an efficient and safe method for cooking
food is provided by portable fire pit system 1.
[0039] It will be understood that any of the foregoing steps may be
amended, reversed or rearranged to allow a user to utilize all of
the features of portable fire pit 1 as desired.
[0040] In the foregoing description, certain terms have been used
for brevity, clearness, and understanding. No unnecessary
limitations are to be implied therefrom beyond the requirement of
the prior art because such terms are used for descriptive purposes
and are intended to be broadly construed.
[0041] Moreover, the description and illustration of the invention
is an example and the invention is not limited to the exact details
shown or described.
