INVENTOR EDGARRBERNIER m \Qs A 7' TOR/VE Y COMPACT FIELD KITCHEN This is a continuation of application Ser. No. 144,608, filed May 18, 1971.

BACKGROUND OF THE INVENTION Camping has become a means of relaxation to millions of people today and camping equipment a necessity to many. Many families find it the only economical way of vacationing. Unless one has the proper equipment (especially with so many women involved in camping) camping can become a chore and hard work rather than relaxation and fun.

Currently the market place is replete with all manner of camping equipment and much of it to do with preparing meals. As a minimum the camper needs a stove to cook his meals and means to store his food, his utensils and his water. It is also convenient to have a sink of some sort for washing dishes and the like. Currently each of these necessities is only singularly available requiring a large amount of bulky equipment to be carried by the camper. This is inconvenient, especially to the camper who may operate out of, for example, a station wagon, trailor or the trunk of his automobile. Furthermore, this is inconvenient to the preparer of the meals. The housewife who may be willing to rough it to some extent would certainly appreciate some of the more basic necessities she is used to when preparing meals at home.

SUMMARY OF THE INVENTION Accordingly, it is an object of this invention to provide a compact field kitchen which can be quickly packed and unpacked.

It is another object of this invention to provide a compact field kitchen which can be disassembled into a portable carrying case.

It is a further object of this invention to provide a compact field kitchen which provides a stove, a sink, a work area and storage space all in one unit which may be folded together to provide a portable carrying case.

Briefly, a compact field kitchen is provided comprising a carrying case having a lower section containing a gas stove and sink and an upper section having storage area for utensils and food with a Windbreaker attached thereto and a worktable attached to the Windbreaker. Retractable legs are attached to the bottom of the lower section. The kitchen is disassembled by folding the worktable into the Windbreaker, the Windbreaker into the upper carrying case section, closing the two sections upon each other and retracting the legs thereby forming a readily portable compact carrying case not must larger than a commercial suitcase.

The compact field kitchen provides a camper with all the major items required in group camping in one space saving, easily transportable, readily assembled unit.

DESCRIPTION OF PREFERRED EMBODIMENTS Referring now to FIG. 1A, there is illustrated thereby a first embodiment of a compact field kitchen comprising a lower carrying case section 10 and an upper carrying case section 12. Sections 10 and 12 are hinged at the junction thereof with a piano hinge (not shown) like a suitcase so that the sections may be folded inward to form a carrying case.

Hinged to upper section 12 are a first pair of wing sections 14 and 16. A mirror 19 is provided on wing 14 and may be used for personal grooming. A second pair of

wing sections

18 and 20 are hinged to the first pair of wing sections 14 and 16, respectively. Arranged at the underside of lower section 10 are four

retractable legs

22, 24, 26 and 28.

Braces

30 and 32 are connected by screws or rivets to

legs

22 and 26, respectively, and to the front portions of

wing sections

18 and 20, respectively.

Wing sections

18 and 20 have U-shaped brackets beneath same to accomodate bent portions of the

braces

30 and 32 when assembled.

The

wing sections

18 and 20 provide worktable surfaces while the wing sections 14 and 16 provide windbreakers especially necessary when cooking.

Arranged within the lower section 10 are a sink 34 and a stove 36. Sink 34 has a drain therein. Lower section 10 has a lip 33 having a groove therein and sink 34 fits into said groove and is screwed into the lip. Lip 33 is hinged to the lowersection 10 and may be lifted up to get at toweling etc. Stove 36 has a sheet metal housing and is screwed onto lip 33. A hose (not shown) may be attached to the drain. Lower carrying case section 10 has a hole therein covered by a sliding plate 38 to permit access to the sink drain, (see FIG. 1C). Gas to run stove 36 is arranged beneath a pair of burners 40 and 42 in bottles 44 and 46. A pair of

controls

48 and 50 control burners 40 .and 42.

A towel rack (not shown) is mounted in lower section 10 and towels 52 are withdrawn therefrom through a slot 54.

When set up, a water container 56 is placed on the uppermost portion of upper section 12 and supplies water through internal plumbing to a faucet. The faucet is stowed in a slot 57 in lower section 10 (see FIG. 4 for details of the faucet). Preferably water container 56 is made of collapsible plastic which collapses as water is withdrawn. The collapsible water container when mounted above the upper section 12 will supply running water by gravity feed without the need for pumping.

Upper section 12 is shown divided into sections by a wall 58 and further divided into smaller sections by

walls

60, 62 and 64. A drawer 66 is inserted between wall 64 and the lowermost portion of upper section 12. The walls 58 64 are not flush with the open end of A battery powered fluorescent light 68 is provided.

The circuit to power light 68 is shown in FIG. 2. A fixture 69 for fluorescent light 68 has slots therein so that the fixture may slide into the upper section when not in use. Pins (not shown) support the fixture at the slots. As shown in FIG. 1A, storage is provided for containers 70, plates 72 coffee pot 74 and cups 76. These items may be dimensionaly designed for the particular unit. Food and other necessities may also be stored in the unit Silverware may be stored in drawer 66. This compact field kitchen may be readily broken down. Water container 56 is emptied of water, collapsed and stored in the recess of sink 34.

Braces

30 and 32 are detached. Wing 18 is folded onto wing 14, wing 20 is folded onto wing 16 and the wings 14 and 16 with

wings

18 and 20 are folded inward against the cabinet areas of upper section 12.

Upper section 12 is then folded upon lower section and closed by clamps 78 (see FIG. 1B). While at :camp the compact kitchen may be left with legs extended, if desired, thus keeping the unit away from the ground.

FIG. 1C shows the compact field kitchen with the legs retracted, ready for storage or portage.

In the fully opened position the unit has a length of five feet yet in the closed position of FIG. 1C, the unit has a width of 30 inches, a depth of 12 inches and a height of 18 inches.

Electricity is provided for fluorescent light 68 by the circuit illustrated in FIG. 2. The power supply is a simple vibrator power supply which may be run for long periods of timefrom a 6 volt dry cell since a relatively low amount of power is used. The DC power source is connected to a pair of terminals 80, and power is supplied through switch contact 82 of a switch also having I transformer secondary. Alternatively, a 12 volt battery may be used with appropriate changes in the rest of the circuit components.

A second embodiment of a compact field kitchen is illustrated in FIGS. 3A, 3B and 3C. This unit is comprised of three main carrying case sections, a center carrying case section 100, a left carrying case section 102 and a'right carrying case section 104. The three sections are preferably hinged together with typewriter type hinges so that the sections may be readily detached' from one another by completely opening the sections. One of the features of this arrangement is that a user may purchase each of the sections separately as his finances and needs dictate.

A worktable area includes a center table area 106, a right wing 108 and a left wing 110. The right and

left wings

108 and 110 are hinged to the center table area I 106 and fold in toward same when not in use. The center table area 106 is hinged to the center carrying case section 100.

When in use, the left and right carrying

case sections

102 and 104 rest on wings. Preferably the wings are not rectangular but are-cutat,.for example, a 30 angle at the inner corners sothat when in use the left and right sections will rest nearer the center of the table and, therefore, prevent wobbling. g

A stove 112 rests on center table area 106 and may be stored in a compartment 114 when not in use. Compartment114 may have one or more fold down shelves 1 15 therein. A water storage unit 116 and sink 1 18 also rest on center tablearea 106 and are stored in a compartment 120. Left carrying case section 102 is a storage cabinet and may have a drawer 121 therein. Right section 104 may contain shelves and drawers for storing pots, pans, etc. When disassembling the unit, the stove, water storage unit and sink are stored in their respective compartments, wings 108 and are folded onto center table area 106, center table unit 106 folded into center carrying case section 100, and the left and right carrying case sections folded into the center section 100 and clamped by clamps 122 (see FIG. 3B). The legs 124 are retracted and a readily portable carrying case remains (see FIG. 3C).

For selling as a modular unit the sink and water storage unit may be part of the left carrying case section 102 rather than the center section thereby more evenly dividing the costs over the individual sections.

A faucet for use in the compact field kitchen of FIG. 1A is illustrated in FIG. 4. Faucet 130 is connected via plastic tubing through holes in the carrying case sections to water container 56. Faucet 130 is slidably arranged in a bushing 134 mounted in lower carrying case section 10. Bushing 134 has a hole 136 therein and a fitting 138 attached thereto. Bushing 134 has a plate integral therewith, which is screwed into the bottom of lower section 10. Upper and

lower seals

139 and 137, respectively, are arranged in bushing 134 to prevent water leak. Tubing 132 is coupled to fitting 138. Faucet 130 is preferably a bent hollow tube having a hole 140 therein. Water is withdrawn from the faucet by pulling up the faucet and rotating same such that the

holes

136 and 140 are aligned thereby permitting water to flow from the tubing through the holes and out the faucet by gravity feed.

The folding legs 22 28 of FIG. 1A may be replaced by the legs illustrated in FIGS. 5A 5D. In this embodiment, lower carrying case section 10 has a pair of peripheral slots at the front and back portions thereof and the legs are folded through the slots into the lower carrying case section and retained there. A pair of legs and 152 are pivotably attached to a pair of

carriage bolts

154 and 156 at the front of the lower carrying case section. A like pair (not shown) is attached to the rear of the carrying case section in the same fashion as in front. A pair of

springs

158 and 160 are attached from a pair of

pins

162 and 164 in the

legs

150 and 152, respectively, to a screw 166. The springs permit the legs to snap outunder tension when they are released.

The release mechanism is illustrated in detail in FIG. 5B and comprises a pair of spring

steel release members

168 and 170 attached to the lower carrying case section 10 by-screws. The

release members

168 and 170 cooperate with saw cuts 172 in leg 150 and its rear counterpart leg 174.

A'pairof wires

176 and 178 coupled to release

members

168 and 170 respectively, are coupled through a hole in a block 180, to a ring 182. Ring 182 is attached to the-carrying case section. Ring 182 is also attached via a wire 184 to a pull rod 186 which is connected through a'hole 188 in the lower carrying case section. When the pull rod 180 is pulled the

release members

168 and 170 are pulled away from the legs causing them to fall through the slots in the lower carrying case section. The leg 152 and its rear counterpart which are resting atop

legs

150 and 174, respectively, also fall down. To retract the legs, they are lifted up and will catch on the

release members

168 and 170.

Preferably, the front legs have vertical cuts therein (not shown) to accomodate a pair of braces 190 and the rear legs have notches 192 therein so that when the legs drop the braces 190 will fall out from the cuts and the free ends thereof drop into the notches 192 (see FIG. 5C).

A feature of the legs whereby the center of gravity of the unit is transferred outward is shown in FIG. 5D. As shown, each of the legs comprise a main lower section 194 and an upper section 196. The upper section is cut at an angle. A 2 angle was used in one embodiment. The upper and

lower leg sections

194 and 196 are connected by a hinge 198. A saw cut 200 is made in the sections and a spring 202 is inserted therein. Spring 202 is connected to a pair of

pins

204 and 206.

Any or all of the features described herein may be incorporated in the portable kitchen units. Thus, it is to be understood that the embodiments shown are illustrations only, and that many variations and modifications may be made without departing from the principles of the invention herein disclosed and defined by the appended claims.
