Description
BACKGROUND OF THE INVENTION
With the ever-expanding interest in camping and less formal summer
travel, through the use of trailerable ten configurations and
campers of other sorts, interest in portable propane cooking stoves
has been stimulated. The stove described in the specification was
designed and developed to be reliable, attractive, and easily
converted between the folded and operating configurations.
A particular objective of the invention is to provide a compact
stove which will be attractive and of such size and shape as to
lend itself easily to packing in automobiles, campers and the
like.
Another objective of the invention is to provide a stove which can
be used with a typical high-pressure propane tank readily available
on the market without the necessity of also purchasing a special
regulator valve for such a tank.
A further objective of the invention is to provide a stove having a
maximum cooking area with minimum overall size.
SUMMARY OF THE INVENTION
Briefly, the invention comprises a two-burner stove, each burner
being housed in a rectangular casing. The casings are hinged
together so that they may be folded with the burners face-to-face,
and form a briefcase style carrying case for the stove. The top
surface of each casing comprises a removable drip pan surrounding
each burner and has mounted thereon means for supporting a working
utensil above the burner head. A handle attached to one or both of
said casings provides means for carrying the base. A fuel supply
line extends from the exterior of one of said casings to one burner
and thence through a flexible extension to the other casing and the
second burner. A pressure regulator mounted within said first
casing regulates the pressure of the fuel supply to the burners. A
folding windscreen is provided for each burner, together with means
for foldably attaching said screens to the associated burner
casing. Flame regulator controls are mounted to each burner with
control knobs extending to the exterior of the housing. A latch
secures the burner casings together in the folded position.
Among the advantages of the invention are:
The stove is small and light in weight with a cooking area twice
its folded size.
Grill is elminated to ease maintenance and cleaning.
Drip pans are removable for ease in cleaning and accessibility to
the stove interior.
A pressure regulator is incorporated within stove housing to
facilitate hookup to a fuel supply.
A separate folding windscreen is provided for each burner.
A BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a perspective view of the stove of the invention in the
folded condition.
FIG. 2 is a perspective view of the stove of the invention in the
opened condition and ready for use.
FIG. 3 is a plan view of the stove of the invention with the drip
pans removed.
FIG. 4 is a side view of a burner suitable for use in the
invention, taken along the line 4--4 of FIG. 3.
FIGS. 5 and 5a show exploded cross-sectional views of a burner
housing illustrating the structure and removability of the drip
pan.
DETAILED EMBODIMENT OF THE INVENTION
Referring to FIG. 1, the case 1 for the stove is illustrated in the
folded position. The case is comprised of a left burner casing 3
and a right burner casing 4, a carrying handle 5 and a latch 6 to
hold the case in the folded position.
Referring to FIG. 2, the burner casings 3 and 4 of the case are
hinged together along a common side by hinges 7 and 8, which permit
the casings 3 and 4 to be folded upwardly and together
face-to-face.
A windscreen 9 is provided along the back and down the outside of
each burner. Preferably, each windscreen will be pivotally attached
to its housing as by hinges 25 in a manner which permits its being
folded flat onto the surface of the burner during storage.
The top surface of each housing 2 and 3 includes a drip pan 10
having an aperture 11 therein to accommodate the upwardly extending
burner head 12. In the absence of a grill, suitable means, such as
the trapezoidal brackets 13, must be provided on the surface of the
drip pan 10 to support a cooking utensil above the burner head
12.
A burner flame control knob 14 for each burner extends outwardly
from the front of each burner casing in the direction of the user.
Rotation of the knob 14 in the conventional manner regulates the
flame of the burner 12.
FIG. 3 shows the stove with the drip pans 10 removed. The burners
12 are supplied by a single fuel line 16 which may penetrate the
casing 1 at any convenient point.
A particularly unique feature of the stove is the incorporation of
a pressure regulator valve 17 within the casing 1. While the
pressure regulator valve 17 may be one of a variety readily
available on the market, its incorporation within the casing 1
ensures ease of connection and safe operating conditions over a
broad range of fuel supply pressures.
As the fuel line 16 must pass from housing 3 to housing 4, and thus
be subjected to bending in the process, care must be taken to
eliminate any sharp edges which could abrade or cut the fuel line
upon the closing of the case.
FIG. 4 is an illustration of a burner suitable for use with the
stove of the invention. Such burners are well known to the art and
do not comprise a part of this disclosure. The top of the burner 12
falls below the top edge 17 of its casing so that when the casings
3 and 4 are folded together, their edges may meet without
interference between the burner heads. A fuel control valve 18, of
a type commonly available upon the market, is provided for each
burner 12. The valve 18 may be secured to the inside of its casing
4 by providing a threaded section 19 which extends through an
aperture in the casing 4, and providing a lock-nut 20, which may be
threaded thereon to draw the valve body tightly against the casing
wall.
Referring to FIG. 5, the top surfaces of the burner casings form a
drip pan 10 and support the brackets 13 for positioning a cooking
utensil above the burners.
The top surface 10 of the casing is depressed over a rectangular
center portion 30, but domes slightly to the burner aperture 11 so
that spills will flow toward the periphery of the depressed portion
30.
A particular advantage of the invention lies in the ease with which
the top surfaces of the casings, referred to herein as the drip
pans 10, can be removed from the housing. The outer edges 31 of the
drip pans 10 overlap the side walls 32 of the casings 3 and 4, and
are provided with small locking catches 33 which engage receiving
apertures 34 in the side walls 32. The drip pans 10 are removed
simply by pressing inwardly, as indicated by the arrows in FIG. 5
until the side wall 32 clears the catch 33 permitting the drip pan
to be lifted clear of the casing.
While we have shown and described only particular embodiments of
the present invention, it will be obvious to those skilled in the
art that the illustrations given and the terms used herein are by
way of illustration and not of limitation, and that additional
changes and modifications may be made without departing from the
present invention in its broadest aspects. Therefore, it is the
intention of the appended claims to cover all such changes and
modifications as fall within the true spirit and scope of the
present invention.
