Description
FIELD OF INVENTION
[0001] This invention relates to the class of stoves and furnaces
and the sub-classification for field stoves. Specifically, this
invention relates to a portable wind barrier for use with a field
stove.
BACKGROUND OF INVENTION
[0002] A field stove or furnace is one that has the fire built on
the ground or in an earthen pit. Sometimes this is referred to as a
bottomless stove, since the fire is being built upon the ground.
There are many different recreational uses for a field stove, such
as cooking while camping, cooking at the beach, or while preparing
deep-fried food such as turkeys.
[0003] Additionally, in many surroundings, people use fires for
warmth while outdoors. Fires at the beach or while camping are both
common.
[0004] The problem with either a field stove or a warming fire is
that the wind can blow out the fire, or misdirect the flames. Wind
can make it nearly impossible to start and kindle an outdoor fire.
Additionally, when using a field stove, the wind can significantly
affect the efficiency and effectiveness of such a fire, by causing
the flame to be misdirected. In other words, the wind blows the
flame in such a way that the flame is no longer effectively
providing heat to the items being cooked.
[0005] In order to improve the field stove experience, a solution
to the wind problem is needed. Since the wind can shift directions,
the solution should be capable of encircling the fire. However, the
solution should allow the user to set the invention around less
than the complete fire, to allow the user to access the fire.
Additionally, when used with a camp or beach fire, the invention
should allow a wind-break while still allowing warming access to
the fire. Last, such a solution has to be portable and easily
transported.
SUMMARY OF THE INVENTION
[0006] This summary is intended to disclose the present invention,
a portable wind barrier for a field stove. The embodiments and
descriptions are used to illustrate the invention and its utility,
and are not intended to limit the invention or its use.
[0007] The portable wind barrier for a field stove prevents the
wind from unduly blowing or interfering with the fire. The portable
wind barrier for a field stove is positioned about the fire,
enclosing the fire. The portable wind barrier weighs a maximum of
20 lbs. The portable wind barrier has a maximum height of 2.5 ft
and a maximum length of 10 ft.
[0008] The portable wind barrier for a field stove is comprised of
a plurality of interconnected panels fabricated from a temperature
resistant, strong material, such as steel, aluminum, or a laminar,
heat-resistant material. The preferred shape for the panels is
rectangular, with all the interconnected panels being of identical
size. The interconnected panels have a substantially planar surface
with two long edges and two short edges. The aspect ratio is the
ratio of the long edge to the short edge. The interconnected panels
are connected to one another along the long edges of the panels
using hinges. The preferred hinges are continuous, or piano, hinges
that run the entire length of the interconnected panel. A
continuous hinge allows the interconnected panels to be folded
together for transport.
[0009] The portable wind barrier for a field stove has two end
interconnected panels. Each end interconnected panel has a free
edge. The two free edges can be connected to one another using a
simple temporary connector, including, but not limited to, a hasp,
latch, or rod and cylinder.
[0010] There should be at least three (3) interconnected panels to
encircle a fire. From a practical standpoint, six (6) to eight ((8)
interconnected panels are ideal, as it minimizes the wind that is
normal to the face of the panels, and allows the portable wind
barrier for a field stove to be positioned and contoured around the
fire.
[0011] The maximum height of the portable wind barrier for a field
stove is the length of the long edge of the interconnected panels.
The maximum length of the portable wind barrier for a field stove
is the length of the short edge of the interconnected panels
multiplied by the number of interconnected panels.
[0012] A functional image is pressed or formed into the planar
surface of each interconnected panel. The functional image provides
both decoration and structural rigidity to the interconnected
panels. By making the functional image out of a series of grooves,
bumps and bend, the functional image will stiffen the panels. The
imprinted sides of the functional image can be aligned so that,
when folded, the functional images nest, reducing the overall
package side of the portable wind barrier for a field stove during
transport. This allows the overall package dimension of the folded
portable wind barrier for a field stove to be minimized.
[0013] The most common material for the interconnected panels is
steel. Galvanized steel (zinc coating), aluminum-coated sheet steel
(hot dip process), or stainless steel are the most appropriate
selections. As with any portable device made with steel, weight can
quickly become an issue with the portable wind barrier for a field
stove. Realistically, the interconnected panels are fabricated from
something between 20 gauge steel (0.0359'' for sheet steel, 0.040''
for galvanized steel, and 0.0375'' for stainless steel) and 30
gauge steel (0.012'' for sheet steel, 0.016'' for galvanized steel,
and 0.0125'' for stainless steel). This means that, at a maximum
(20 gauge galvanized steel), the portable wind barrier for a field
stove weighs 1.656 lbs/sq. ft. At a minimum (30 gauge stainless
steel), the portable wind barrier for a field stove weighs
approximately 0.5 lbs/sq. ft.
[0014] To be practical, the portable wind barrier for a field stove
should be at least 1.5 ft (approximately 460 mm) tall, and at least
4 ft (approximately 1.2 m) long. The length would be the short edge
length of each interconnected panel multiplied by the number of
panels. At maximum, the portable wind barrier for a field stove
should be approximately 3.0 ft, (approximately 910 mm) tall by 10
ft. (approximately 3.0 m) long. This means that the portable wind
barrier for a field stove will be between 6 sq. ft. ("small") and
30 sq. ft. ("large") in area.
[0015] In order for the portable wind barrier for a field stove to
be easily transported and moved, it needs to be a weight that is
manageable for most people. A gallon of water weighs approximately
8.3 lbs. A twelve pack of beer in cans weighs about 9.8 lbs. An
adult should be able to easily transport and wield something that
weighs between 10 lbs. and 20 lbs. To bracket the dimensions of the
portable wind barrier for a field stove, 10 lbs. of galvanized 20
gauge sheet steel is approximately 6.0 sq. ft., and 20 lbs of
stainless 30 gauge sheet steel is approximately 40 sq. ft.
[0016] This means that a small portable wind barrier for a field
stove can be made out of 20 gauge galvanized steel. However, a
large portable wind barrier for a field stove should be made out of
30 gauge galvanized or stainless sheet steel.
[0017] The present invention clearly can be made in several
embodiments by varying the number of panels, the aspect ratio of
the panels, and the overall size of the panels.

DETAILED DESCRIPTION OF THE DRAWINGS
[0027] The following descriptions are not meant to limit the
invention, but rather to add to the summary of invention, and
illustrate the present invention, a portable wind barrier for a
field stove. While embodiments of the invention are illustrated and
described, the embodiments herein do not represent all possible
forms of the invention. Rather, the descriptions, illustrations,
and embodiments are intended to teach and inform without limiting
the scope of the invention.
[0028] FIGS. 1 and 2 show the present invention 1 a portable wind
barrier for a field stove 1. The portable wind barrier for a field
stove 1 is comprised of a plurality of interconnected panels 2 with
a coupling 50. In this embodiment, there are eight (8)
interconnected panels 2. A minimum of three (3) interconnected
panels 2 are needed in order to enclose a fire. From a practical
standpoint, there should be at least six (6) interconnected panels
2 in order to manage the amount of wind normal to the face of each
interconnected panel 2.
[0029] Each interconnected panel 2 has a top edge 8, a bottom edge
4 and two vertical edges 6. There are two free edges 5, 10 on the
end interconnected panels. The interconnected panels 2 are attached
with a plurality of hinges 9. There is one less hinge 9 than
interconnected panels 2. The interconnected panels 2 have a
substantially planar surface 7 with a functional image 3. The
interconnected panels 2 can be positioned in relationship to one
another, creating an enclosed surface, using the hinges 9.
[0030] FIGS. 3 and 4 show the present invention 1 in situ. This
embodiment of the present invention 1 is composed of eight (8)
interconnected panels 2, which act as a barrier, blocking the fire
41 from the wind 20. The portable wind barrier for a field stove 1
can be contoured around the fire 41 by adjusting the relative
position of the interconnected panels 2 using the hinges 9. The two
free edges 5, 10 of the portable wind barrier for a field stove 1
can be connected to each other using a connector 50, so that the
portable wind barrier for a field stove 1 encloses the fire 41.
[0031] A cooking vessel 34 is placed on a fire 41 rack 40. A
variety of food, such as lobster 30, fish 31, chicken 32, or other
food, can be cooked over the fire 41. The vessel 34 has an interior
33 and an exterior 37. The interior 33 can be filled with water.
Typically, the vessel 34 is a large boiling pot 34 with handles 35.
Additionally, food can be grilled directly on a rack 40 or grill.
The hinges 9 allows the interconnect panel 2 configuration to be
contoured to fit the needs of the particular fire 41
[0032] FIG. 5 shows an example of a connector 50, 60 to secure the
two free edges 5, 10 to one another. Many types of latches and
hasps can connect the two free edges 5, 10. In this embodiment, the
female connector 50 has a cylinder 51 in its bottom surface 56 that
accepts a rod 61. The exterior surface of the rod 62 is smaller
than the interior surface of the cylinder 51, allowing the rod 61
to fit in the cylinder 51, and be captured. The male connector 60
is attached to a free edge 5, 10 of a panel 2 with a shank 63.
Likewise, the female connector 50 is attached to a free edge 5, 10
of a panel with a shank 52. The male connector 50 has an exterior
cylindrical surface and a top 54. The exterior cylindrical surface
55 is mated with the shank 52, shortening one side 53 of the
exterior cylindrical surface 55
[0033] The interconnected panels 2 are fabricated from a material
that is impervious to the temperatures generated by a field stove,
such as steel. Galvanized steel (zinc coating), aluminum-coated
sheet steel (hot dip process), or stainless (chromium) steel are
the most appropriate materials. As with any portable device made
with steel, weight can quickly become an issue with the portable
wind barrier for a field stove 1. Realistically, the interconnected
panels are fabricated from something between 20 gauge steel
(0.0359'' for sheet steel, 0.040'' for galvanized steel, and
0.0375'' for stainless steel) and 30 gauge steel (0.012'' for sheet
steel, 0.016'' for galvanized steel, and 0.0125'' for stainless
steel). This means that, at a maximum (20 gauge galvanized steel),
the portable wind barrier for a field stove 1 weighs 1.656 lbs/sq.
ft. At a minimum (30 gauge stainless steel), the portable wind
barrier for a field stove 1 weighs approximately 0.5 lbs/sq.
ft.
[0034] To be practical, the portable wind barrier for a field stove
1 should be at least 1.5 ft (approximately 460 mm) tall 6, and at
least 4 ft (approximately 1.2 m) long. The length would be the edge
length 8, 4 of each interconnected panel 2 multiplied by the number
of panels. At maximum, the portable wind barrier for a field stove
1 should be approximately 3.0 ft, (approximately 910 mm) tall 6 by
10 ft. (approximately 3.0 m) long. This means that the portable
wind barrier for a field stove will be between 6 sq. ft. ("small")
and 30 sq. ft. ("large") in area.
[0035] In order for the portable wind barrier for a field stove to
be easily transported and moved, it needs to be a weight that is
manageable for most people. A gallon of water weighs approximately
8.3 lbs. A twelve pack of beer in cans weighs about 9.8 lbs. An
adult should be able to easily transport and wield something that
weighs between 10 lbs. and 20 lbs. To bracket the dimensions of the
portable wind barrier for a field stove 1, 10 lbs. of galvanized 20
gauge sheet steel is approximately 6.0 sq. ft., and 20 lbs of
stainless 30 gauge sheet steel is approximately 40 sq. ft.
[0036] This means that a small portable wind barrier for a field
stove 1 can be made out of 20 gauge galvanized steel. However, a
large portable wind barrier for a field stove 1 should be made out
of 30 gauge galvanized or stainless steel.
[0037] A certain amount of structural rigidity is created by using
a larger number of interconnected panels 2. Additional structural
rigidity is created by stamping or pressing the functional image 3
into the interconnected panels 2. It is well known in the sheet
metal art that changing the profile of sheet steel will add
significant stiffness, whether by making a groove, bump, or bend.
In other words, the functional image 3 is pressed or stamped into
the planar surface of each interconnected panel 2 in such a way
that the functional image 3 is no longer co-planar with the rest of
the planar surface 7. The functional image 3 is essentially a
combination of grooves and bumps. By using images with aspect
ratios that match that of the interconnected panels 2 such as a
fish 3, the overall interconnected panel 2 achieves significant
stiffness.
[0038] FIG. 6 shows the functional image 3 causes a bump along the
long dimension of the interconnected panel 2 planar surface 7. FIG.
7 shows the function image 3 causes a bump along the short
dimension of the interconnected panel 2 planar surface 7. The
functional images 3 of adjacent interconnected panels 2 can be
oriented so that, when the portable wind barrier for a field stove
1 is folded for transport, the functional images 3 nest into one
another.
[0039] FIG. 8 shows an alternative embodiment of the portable wind
barrier for a field stove 101. The portable wind barrier for a
field stove 101 is comprised of a plurality of interconnected
panels 102. In this embodiment, there are eight (8) interconnected
panels 102. Each interconnected panel has a top edge 108 and a
bottom edge 104. There are two free edges 105, 110 on the end
interconnected panels. The interconnected panels 102 have a
substantially planar surface 107 with a functional image 103.
