Abstract

ABSTRACT
A portable, collapsible, light-weight barbeque has sides with a laminated paper exterior and a metal foil interior with a heat shield therebetween.
The side walls are formed from four inverted trapezoidal panels that can be interconnected to one another along their side edges. The barbeque is designed to burn newspaper and can provide up to twelve minutes of cooking time with no more than six double sheets of newsprint. The burning of the newsprint is automatically controlled so that the temperature at the grill is substantially constant at approximately 400°F during the cooking time. The bottom and sides of the barbeque remain relatively cool to the touch. While the barbeque is inexpensive enough to be disposed of after one use, it is durable enough to provide at least ten uses.

Description

~3~6~3 This invention relates to a high efficiency, portable, collapsible, light-weight barbeque that is designed to burn only paper and to a method of using said barbeque. In particular, this invention relates to a barbeque having exterior side walls formed of paper material and being efficient enough to use only a few sheets of newsprint as fuel.
It is known to have collapsihle, portable barbeques that are designed to burn paper, including olc newspapers or the like. One such type of barbeque is described in U.S. Patent Number 4,149,514 (Joseph A. Latouf). Unfortunately, previous barbeques that are designed to burn only paper are too expensive to manufacture, are not light-weight and cannot be easily transported, do not provide sufficient burning of the paper, do not control the burn, do not produce constant heat or are unsafe, particularly when used in areas where children are playing or they are extremely inconvenient in that additional paper must be added virtually continuously during their use.
There are numerous other barbeques, while not designed to burn paper alone, are designed to be relatively inexpensive, easily transportable and disposable. For example, see U.S. Patent Numbers 3,682,154 (George A. Mollere), 4,531,506 (Charles E.
Chambers, et al.) and 4,254,863 (Michael W. Katcs, et ; al.). Unfortunately, these disposable barbeques are relatively complex, they are unsafe, they are expensive to operate in that they contain specially designed fuel packs, they are much too expensive to throw away after one use, they do not provide sufficient cooking area, they do not provide satisfactory cooking results, they require a relatively lengthy cooking time, or, they are ~3~S3 extremely difficult to clean if a user does not wishto discard them after one use.
Despite these numerous prior attempts to design a portable, collapsible, liyht-weight barbeque that can also be disposable, none of the barbeques referred to in the prior art patents have achieved widespread public acceptance. Orle of the most popular barbeques presently on the market: is a relatively small non-collapsible barbeque with metal walls sold under the name ~IB~C~I (a trade mark), which has been enormously popular with consumers for a number of years. The HIBACMI barbeque is relatively expensive and has two apparent disadvantages relative to the barbeque of the present invention. Firstly, the HIBACHI barbe~ue is not collapsible or light-weight and is not easily transportable, particularly when it must be carried by hand for any distance. Secondly, the HIBACHI barbe~ue burns charcoal and therefore has all of the well known disadvantages oE charcoal in that it can be difficult to light and often ~akes a great deal of time before it achieves a burn level that is suitable for efficient cooking. With present day consurners, cooking time and convenience of use are extremely important. It is not unusual for users of a charcoal-fired barbeque to cook their meal prematurely before the charcoal is ready for cooking thereby achieving unsatisfactory cooking results. Charcoal also has the inherent danger of disposing of coals that have not been properly extinyuished. Also, handling of the charcoal can be extremely messy, both in igniting the charcoal and disposing of it after the coals have been doused with water.
Time is becoming increasing important to today's consumers as evidenced by the rapid growth in - ~L3~S~
fast food services which are providing stiff competition to regular restaurants. Similarly, charcoal barbeques are now seldom purchased for home use but are instead heing replaced by gas-fired barbeques which provide large time savings are are much more convenient than char~oal burning barbeques.
Unfortunately, most gas-fired barbeques are not sufficiently portable to have achieved widespread use away from the home, for example, on picnics, camping and canoe trips, hikes and wilderness tours. For some time, there has been a demand for a barbe~ue that is safe, portable, collapsible, inexpensive and e~ficient enough to provide cooking times from ignition of the fuel to the end of cookin0 of less than fifteen minutes, said barbeque being light enough to carry conveniently in a back-pack and yet durable enough to endure several uses.
A portable, collapsible, light-weight barbeque for use on a supporting surface is designed to efficiently use paper as the only fuel. The barbeque has a plurality of panels interconnected to one another to form side walls of the barbeque. The panels are shaped so that the barbeque increases in cross-sectional size ~rom bottom to top. Each panel has a laminated paper exterior and a metal foil interior with a heat shield therebetween. The interior and exterior both adhere to said heat shield.
There are means for interconnecting said panels along adjacent side edges thereof. A grill is supported by ;~ 30 said panels at or near a top thereof. A base for thebarbeque is located at or near a bottom of said panel, ~ said base extending between and being supported by said panels. A grate is supported by said panels between said base and said grill, said gxate providing ~3~5~
support for said ~uel. Air inlet vents are located in said barbeque beneath said grate.
A method o~ barbequing uses a portable, collapsible, light-weight barbeque on a supporting surface, the barbeque being designed to efficiently use paper as the only fuel. The barbeque has a plurality of panels interconnected to one another to form side walls of the barbeque. The panels are shaped so that the barbeque increases in cross-sectional size from bottom to top. There are meansfor interconnecting said panels along adjacent side edges thereof. The barbeque has a grill supported by said panels at or near a top thereof. A base is located at or near a bottom of said panels ancl extends between and is supported by said panels. A grate is supported by said panels between said base ancl said grill. The grate provides support for said grill.
The base is used in conjunction with anchor means, the barbe~ue containing tiny air inlet vents located beneath said grate. The method includes the steps of:
(a) interconnecting the panels to one another along their side edges to form the continuous side walls of the barbeque;
~'D) installing said base at or near a bottom of 2S said barbeque;
(c) anchoring said base on said supporting surface so that the barbeque will not tip over when subjected to normal winds;
(d) installing said grate above said base approximately twenty percent of the distance from a bottom and top of the barbeque;
(e) crumpling up two to six double sheets of paper;
(f) dropping said crumpled paper onto said ~3~6~5~
grate;
(g) installing said grill on said panels at or near a top of said barbeque~
(h) igniting said crumpled paper;
~i) waiting approximately thirty seconds for the intial flare-up to die down;
(j) placing food to be cooked on said grill;
lk) cooking said food as desired for up to approximately twelve minutes;
(l) removing said food from said grill when the level of cooking has been achieved;
(m) allowing said barbe~ue to cool;
~ (n) ultimately reversing steps (a) to (f) to - dismantle said barbeque.
In the drawings, there is shown a preferred embodiment of the invention:
Figure l is a perspective view of a barbeque;
Figure 2 is a perspective view of the barbeque with two panels removed to expose an interior;
Figure 3 is a side view of an interior of one panel;
; Figure 4 is a sectional view of one panel;
Figure 5 is an expanded sectional view of a .~ ridge of one panel;
Figure 6 is an expanded sectional view of a channel of one panel;
Figure 7 is a side view of a panel when viewed from an exterior, with various layers partially cut away.
Referring to the drawings in greater detail, in Figures l and 2, there is shown a perspective view of a barbeque 2 having four panel~ 4 interconnected to ~ :

- ~L38~S3 one another to form side walls of the barbeque. The panels are shaped so that the barbeque increases in cross sectional size from a bottom 6 to a top 8~ It can be seen that the panels 4 are identical to one another and have an inverted trapezoidal shape~ For appearance purposes, two top corners 10 of each panel 4 are rounded. The two panels 4 in the foreground of Figure 2 are removed so that an interior of the barbeque can be viewed.
Each panel has two side edges 12, 14 with ~ means for interconnecting the panels located along ; adjacent side edges thereof. In the bottom of the barbeque, there is located a base 16 which extends -~ between and is supported by the panels 4. The base 16 is preferably made of stiff, metallic material that is friction fit against the sides of the panel. An opening 18 in a centre o~ the base 16 allows the barbeque to be anchored through said opening to a supporting surface (not shown). For example, a spike can be driven through the opening 1~ into the supporting surface. Alternatively, a rock or rocks of suitable size can be placed inside the barbeque on top of the base. The purpose of anchoring the barbeque is to prevent it from being blown over by the wind.
Preferably, the base is made from metal foil and, still more preferably, from embossed metal foil having a thickness of at least 35 gauge (ie. 35/thousandths of an inch). Still more preferably, the foil has a thickness of 50 gauge. A grill 20 is supported by the panels 4 at or near a top 8 thereof. A grate 22 is supported by the panels 4 between the base 16 and the grill 20. The grate provides support for the fuel used in the barbeque (not shown). From Figure 2, it can be seen that the location of the grate is less ; - 6 -3~ 5;3 than one fourth of the distance between a bottom and top of each panel.
Between the grate 22 and the base 16, there are located a plurality of air inlet vents 24. The vents are small enough to retard consumption of fuel yet large enough to achieve a temperature at said grill of substantially 400F for approximately twelve minutes from not more than six clouble sheets of paper used as fuel. Even though the grill is 400F, the base and exterior side walls remain relatively cool to the touch. In this way, the barbeque of the present invention is safer than barbeques having metal side walls. For example, if the barbeque is used on grass as the supporting surface, the base 16 will not get so hot as to burn the grass or make it turn yellow.
In Figure 3, there is shown a side view of a panel 4 when viewed from an interior thereof. An interior surface of each panel is made of metal foil and there is an upper ledge 26 formed in said metal foil interior near a top of each panel. The ledge is located so that the four ledges 26 togetherr one for each panel 4, support the grill 20 at an appropriate height near the top of each panel. A lower ledge 28 is formed in the metal foil interior near a bottom 6 of each panel. It can be seen that the ledge 2~ is less than one ~uarter of the distance between the bottom 6 and the top 8 of the panel 4 and is actually substantially sixteen percent of that distance. The four lower ledges 28 together support the grate 22.
Air inlet vents 24 are located substantially half the distance between the lower ledge 28 and the bottom 6 of each panel. There are two air inlet vents on each panel. Each inlet vent 24 is spaced approximately midway between an imaginary centre line of each panel :

and a side edge thereof. The two side edges 12, 14 of each panel 4 are preferably at an angle of substantially 79 to an upper edge or top 8 of each panel. Variations can be made in this 79 angle.
Howe~er, this angle determines the slope of the side walls of the barbe~ue. If the slope was too steep, the side walls would absorb too much heat and will or tar. On the other hand, if the slope of the side walls is too shallow, a temperature of substantially 4000F at the grill 20 will not be able to be maintained over a sufficiently long period ~rom a minimum supply of paper. It has been found through experimentation that an angle of substantially 790 provides sufficient heat to the grill for cooking purposes and yet will not result in the walls wilting, charring or burning.
In Figures 4, 5 and 6, the two side edges 12, 14 of each panel 4 are shown in detail. The side edge 12 is a ridge and the side edge 14 is a corresponding channel. The ridge and channel are angled relative to one another to provide means for interconnecting the panels 4 along adjacent side edges by engaging the ridge 12 from one panel in the channel 14 of an adjacent channel. The ridge 12 and channel 14 shown in Figures 4, 5 and 6 is formed in the metal foil interior 30 of each panel 4. The ridge 12 and channel 14 are rectangular shapes that are oriented normal to one another to accommodate the square cross-section of the barbe~ue when it has four panels. The ridge and channel are siæed relative to one another so that the ridge 12 of one panel fits snugly within the channel 14 of an ad~acent panel.
The base 16 is formed of a non-flammable material with a sufficiently high melting point so ~L3~69~5i3 that it can receive ashes from the grate without being damaged.
In Figure 7, there is shown a side view of a panel 4 when viewed frQm an exterior thereof with S outer layexs partially cut away. An exterior of each panel 4 is made of laminated paper 32. The interior is made of metal foil 30 with a heat shield 34 therebetween. The exterior 32 and the interior 30 adhere to the heat shield 34. The hea~ shield 34 is a wire screen laminated between the interior 30 and the exterior 32 by a heat resistant adhesive, preferably a thermosetting silicate adhesive. The laminated paper exterior 18 selected from the group of mat board or match splint and, still more preferably, has a thickness of approximately 6S mil. Alternatively, though not as desireable as mat board or match splint, the exterior can be made from cardboard. The metal foil interior is preferably tin foil and, still more preferably has a thickness of approximately S0 gauge (ie. 50/thousandths of an inch). Each panel preferably has sufficient thickness that an exterior 32 will not darken, char or warp when the barbeque is properly used. The heat resistant adhesive is thick enough to embed the wire screen 34 so that it does not contact the interior metal foil or the exterior ; laminated paper.
While the barbeque of the present invention can be made in any convenient size, it has been found that a barbeque having the following sizes works well:
; 30 ~i) each panel - twelve inches wide at the top and nine and one-half inches wide at the bottom with a ~ fourteen inch height;
; (ii) grate - located five inches above the _ g _ ~3~ 3 bottom;
(iii) vents - located two and one-half inches above the bottom;
(iv) inside diameter of each vent, two vents per panel - flve-sixteenths inches.
While the scope of the invention is not limited to the foregoing dimensions, these dimensions result in a barbeque having a weiyht equal to or less than 2.75 pounds. Also, the volume of air space below the grate is twenty-two percent of the volume of air space between the panels above the grate.
Preferably, the foil interior wraps around a top 8 and bottom 6 o each panel to assist in holding the laminated paper exterior in place. The wire mesh heat resistive adhesive combination, in addition to providing a heat shield, also increases the strength of the panel by approximately fifty percent.
Preferably, the unassembled components of the barbeque are stored in a flat cardboard box having a trapezoidal shape corresponding to the shape of the panels. When it is desired to assemble the barbeque, the four panels are first interconnected along their side edges by successively sliding the ridge of one panel into the channel of an immediately adjacent 2S panel. When the four sides are properly assembled, the base is placed in a bottom of the barbeque and anchoring means are employed to anchor said base onto a supporting surface. Examples of anchoring means are a spike that is driven through an opening in the base into the supporting surface or a rock or rocks of sufficient size so that the barbe~ue will not tip over when subjected to normal windsO Next the grate is placed on the lower ledges and the paper is tossed onto the grate. The paper is crumpled up into balls ~3~6~3 and preferably twisted into short log-shaped pieces.
Preferably, the paper is newsprint.
When the term "double sheet of paper" is used in this specification, it shall be interpreted to mean a sheet of paper having a size equal to four pages of a standard size newspaper ~ie. approxima~ely ; 14 inches by 24 inches).
When sufficient paper has been crumpled up and tossed onto the grate, the grill can be installed by setting it onto the upper ledges of the panels.
The number of double sheets of paper, which will normally range from two to six, will vary depending on the type of food that is being cooked as that will determine the desired cooking time.
The crumpled paper is then ignited, preferably with an extra long match. Upon ignition, the paper will flare-up or flame for appxoximately thirty seconds. As soon as the flare-up dies down, the food to be cooked is placed on the grill and cooked as desired. When the desired level of cooking has been achieved, the food is removed from the grill~
While the food is keing consumed, the barbe~ue will cool. It has been found that the paper burns very efficiently and the ash remaining is white in colour '~ 25 and extremely fine. The grill, grate and base are -~ removed and the ashes are appropriately discarded.
The panels are then disassembled by removing the ; ridges of one panel fxom the channels of the immediately adjacent panels. The components of the barbe~ue are then placed in the flat cardboard container that is provided for that purpose.
While the barbe~ue of the present invention is so inexpensive that it could be discaxded after each use, it is designed to be strong enough to ,....::: ~ ,.
., - .. ...

~ ~ 306~3 provide for at least ten uses before it must be discarded. With careful use, the barbeque of the present invention could be used many more than ten times.
The paper exterior can be used for advextising purposes or to otherwise provide the barbeque with a pleasing aesthet:ic appearance.
As can be appreciated, compared to barbeques that are fueled by charcoal, the paper burning barbe~ue of the present invention will ignite very quicXly and provides and extremely fast cooking time from ignition to completion of the cooking. ~lso, a minimum amount o~ paper is re~uired. This is particularly important when the barbeque is used on a hiking or wilderness trip as one does not want to carry large amounts of paper to fuel the barbeque.
For example, it has been found that hot dogs can be satisfactorily cooked in less than three minutes ~rom the time of ignition of the paper using no more than three double sheets of paper and preferably two double sheets o~ paper. Similarly, it has been ~ound that hamburgers can be cooked in no more than five minutes using no more than three double sheets o~ paper.
Further, it has been found that an eight ounce steak can be cooked in seven minutes or less using no more than three double sheets of paper. When six double sheets of paper are used, more than twelve minutes of cooking time will generally result.
The barbeque is portable, collapsible, light-weight and can even be termed disposable. It can be used to provide quick and ef~icient heat at virtually no operating cost.
