Abstract

A demountable grill for use over a cooking fire and including support channels retained against separation and having grill rods insertable transversely through one channel in holes aligned but not normal to the channel and into the other channel; additional rods or support structure binding the channels to be relatively fixed, and a demountable and extendible horizontal rod spaced above the grill for supporting a reflector media to concentrate reflected heat upon items on the grill.

Claims

1. A camp grill comprising:

a pair of rigid channels opposite each other in widely spaced relation, each of said channels having an inner flange and an outer flange lying parallel thereto and a web interconnecting said flanges, and each of said channels also having an open, unobstructed interior between the flanges, the inner flanges of said channels confronting each other in widely spaced relation and having a plurality of support apertures therein, means retaining said channels against movement away from each other and including a retaining rod extending between said channels and through apertures thereof and into the interior thereof, said rods having means on the ends thereof to engage and retain said channels in assembly therewith and against movement away from each other, and a plurality of support rods extending between said channels and snugly through said support apertures and transversely across said open interior, the ends of said support rods being disposed within the interior of said channels and bearing against said outer flanges of said channels under pressure to produce a frictionally binding relation with the channels whereby to provide against unintended disassembly of the rods and channels and to rigidify the rods with respect to the channels.

2. The camp grill according to claim 1 and one of said channels having a transverse size smaller than the open interior of the other of the channels to be received and stored therein.

3. The camp grill according to claim 1 wherein said retaining rod has crimped ends bent at approximately right angles with respect to the rod and bearing against the inner side of the inner flanges to produce sliding of the channels along the support rod when the channels are tilted with respect to the support rods.

4. A camp grill comprising:

a pair of rigid channels opposite each other in widely spaced relation, each of said channels having an inner flange and an outer flange and a web interconnecting said flanges and each of said channels also having an open and unobstructed interior between the flanges, the inner flanges of the channels confronting each other and having a plurality of rod support apertures therein, the outer flange of one of said channels having a plurality of rod threading apertures, each disposed opposite a respective support aperture, each of the rod threading apertures being aligned with the corresponding support aperture in a direction transversely and obliquely of the channel, means retaining said channels against movement away from each other, and a pluralitY of support rods extending between said channels and through said support apertures of the channels and transversely across the open interiors thereof, said support rods being disposed out of alignment with said threading apertures to be retained in assembly with the channels, and said channels being movable relative to each other to align the support rods with said threading apertures to facilitate removal thereof and disassembly of the rods and channels.

5. The camp grill according to claim 4 wherein the ends of said support rods bearing tightly against the outer flanges of said channels to rigidify the rods with respect to the channels.

6. A camp grill comprising:

a pair of rigid channels opposite each other in widely spaced relation, each of the channels having an inner flange and an outer flange and a web interconnecting said flanges, and each of said channels also having an open and unobstructed interior between the flanges, the inner flanges of the channels confronting each other and having a plurality of support apertures therein, means retaining said channels against movement away from each other, a plurality of support rods extending between said channels and through said support apertures and transversely across the open interiors of said channels, the ends of said support rods confronting the outer flanges of said channels whereby to provide against unintended disassembly of the rods and channels, said rods having a loose fit with respect to the support apertures of one of the channels to permit tilting of the channel with respect to the rods and to swing the outer flange thereof transversely of the rods and out of confronting relation with the ends of the rods whereby to permit the rods to be withdrawn from the support apertures and disassembled with respect to the channels, and the ends of said rods bearing tightly against the outer flanges of the channels in a frictionally binding relation to rigidify the rods with respect to the channels.

7. A camp grill comprising:

a pair of rigid channels opposite each other in widely spaced relation, each of said channels having an inner flange and an outer flange and a web interconnecting said flanges, and each of said channels also having an open and unobstructed interior between the flanges, the inner flanges of the channels confronting each other and having a plurality of support apertures therein, the outer flange of one of the channels having a plurality of rod-threading apertures each disposed opposite a respective support aperture, each of the threading apertures and the corresponding support aperture being aligned with each other in a direction transversely and obliquely of the channel, means retaining said channels against movement away from each other, and a plurality of support rods extending between said channels and through said support apertures and transversely across the open interiors of said channels, the ends of said support rods confronting the outer flanges and out of alignment with said rod-threading apertures, the channels being movable relative to each other to align the support rods with said rod-threading apertures to facilitate removal of the rods and disassembly of the grill.

8. The camp grill according to claim 7 and means frictionally bearing against said channels to restrain longitudinal movement thereof to retain the support rods out of alignment with the rod-threading apertures.

9. The camp grill according to claim 8 and said means frictionally bearing against the channels including additional rods with ends frictionally bearing against the outer flanges of the channels and rigidifying the channels and support rods relative to each other.

10. The camp grill according to claim 8 and said means frictionally bearing against said channels including a rigid bar extending between the channels and having horizontal socket openings in which the ends of the channels are received and secured whereby to restrain movement of the channels with respect to each oTher and maintain the support rods out of alignment with the rod threading apertures.

11. A camp grill comprising:

a pair of rigid channels opposite each other in widely spaced relation, each of said channels having a pair of parallel flanges and a web interconnecting said flanges and also having an open and unobstructed interior between the flanges, one flange of each channel confronting the other channel and having a plurality of support apertures therein, the other flange of one of the channels having a plurality of rod-threading apertures therein aligned with said support apertures in transversely, but oblique relation relative to the channel, one of said channels being of a reduced cross-sectional size relative to the other channel to facilitate assembly of the channels together to create a storage receptacle, one of the channels having flanges across the open ends thereof for retaining the contents of the receptacle so formed;

a pair of retaining rods extending between the opposite channels and said rods being respectively disposed adjacent the opposite ends of said channels, said retaining rods extending through support apertures of said channels and being bent at right angles within the channels to prevent separation of the channels away from each other; and

a plurality of substantially rigid support rods extending between said channels and through said support apertures and transversely across said open interiors of the channels, said support rods being approximately the same size as the apertures and said rods lying adjacent the web of the channels, the ends of said rods being disposed out of alignment with said threading apertures, and said channels being tilted slightly with respect to the rods to wedge the ends of the rods against the outer flanges of the channels and rigidify the relation between the rods and channels.

12. A camp grill comprising:

an upright hollow standard to be supported from the ground;

a horizontal and rigid crossbar having an aperture therethrough and of a size closely conforming to the size of said standard and receiving the standard therethrough in close fitting relation, said crossbar also having opposite ends and a pair of horizontal openings therethrough respectively disposed adjacent the opposite ends;

a pair of elongate channels each extending through a respective horizontal opening in the crossbar and said channels being disposed in widely spaced and confronting relation with each other, each of said channels having an inner depending flange confronting the opposite channel and having a plurality of rod support apertures therein, one of said channels also having a plurality of threading apertures in the outer depending flange, each of said support apertures having alignment with a corresponding threading aperture in transverse but oblique relation with the channel;

a retaining rod extending between said channels in widely spaced relation with respect to the crossbar and extending through corresponding support apertures in said channels, said retaining rod having crimped ends bent at approximately 90* bearing against the interior of said channel flanges and retaining said channels against divergent movement;

a plurality of support rods extending between said channels and said rods having ends projecting through the support apertures of the channels and into the unobstructed interior of the channels, said support rods normally being out of alignment with said threading apertures, but being swingable into alignment with the threading apertures for removal therethrough upon relative endwise movement of said channels in the openings of said crossbar;

an extendible and retractable horizontal support bar spaced above said rods and approximately midway between said channels for supporting a reflective foil draped thereover and over said channels for reflecting heat onto the articles carried by the rods; and

a telescoping channel inserted into the hollow standard and beIng pivotally connected to said extendible bar for supporting the same and receiving said bar, upon collapse, into small compass within the channel.
