Description
Background and Summary of the Invention
This invention relates to a camper's grill, and more particularly to a portable camper's cooking apparatus of improved design.
The apparatus is of the pyramidal tripod type and contemplates utilization of a grill which hangs from the tripod apex and which is easily assembled and dis-assembled. One of the tripod legs is larger in diameter than the others and is adapted to storingly receive all of the other components of the device. In addition, the said larger leg is formed at one end to have multi-functions, i.e. (1) it provides a guide for the grill hanging cable; (2) it provides a stop for the other tripod legs when the unit is assembled; and (3) it provides a stop to prevent fall-out of all the other components when they are stored therein. Furthermore, a wind guard is provided which selectively protects one lower side of the apparatus or alternately all three upper sides thereof.

Description of the Preferred Embodiment
As best shown in FIGS. 1 and 2 of the drawings, the tripod cooking device comprises a pair of elongated legs 1 of relatively small diameter, and a third leg 2 of relatively large diameter and which forms a hollow tube. The lower ends of each leg are adapted to engage a supporting surface, such as the ground 3. A grill assembly 4 is connected to corner mount cables 5, which merge into a single cable 6, with the latter passing over the tripod apex and terminating in a cable hook 7 of suitable bent design to lock the cable at any position along large leg 2. Grill assembly 4 may thus be selectively suspended at any desired height.
It is contemplated that the upper or apex end of leg 2 is formed in a unique manner to provide a multiplicity of functions. For this purpose, and as best shown in FIGS. 3 and 4, an edge portion of the upper leg end is bent radially inwardly to form a curved lip 8 forming a groove-like guide 9 over which grill cable 6 passes. The opposite edge of the end of leg 2 is shown as bent radially outwardly to also form a second cable guide 10. This construction eliminates the need for expensive and complicated pulleys, for it has been found that cable 6 will readily slide in the guides.
The basic tripod is assembled by passing the upper end portions of small legs 1 angularly through suitably positioned openings 11 in the walls of leg 2 adjacent the upper end of the latter, until the small leg ends engage curved lip 8. The latter thus also acts as a stop means to limit penetration of legs 1 into leg 2 and thereby stablilize the unit.
Grill assembly 4 is best illustrated in FIGS. 5-8. The assembly comprises a pair of longitudinally extending spaced generally inverted L-shaped elongated side channel members 12, with each member having a generally vertical outer flange 13 which merges through an upper curved portion 14 into an angularly downwardly inwardly extending flange 15. The latter flanges are provided with a plurality of longitudinally spaced transversely elongated slots 16, the lower inner edges 17 of which function as supports for grill rods 18.
As shown in FIGS. 5 and 6, in assembling the grill, members 12 are positioned in parallel spaced-apart relationship. Rods 18 are then initially laid downwardly between members 12 so that the ends of each rod vertically enter opposed slots 16 and rest on edges 17. Because of the slots, the actual distance between members 12 may be somewhat varied or the rod lengths varied, but rods 18 will still enter the slots.
Referring to FIGS. 6 and 7, pressing of members 12 toward each other will cause the members to slide on the rods until the rod ends engage outer stop flanges 13 to create a stable rectangular grill. The rods are retained against vertical upward movement by the top edges of slots 16. In addition, the end rods 18 are of greater length than the other rods and are adapted to pass outwardly through openings 19 at each end of members 12. The extended ends of the end rods 18 are provided wih grooves 20 which receive support loops 21 disposed on the lower ends of cables 5. Not only do loops 21 hangingly support the grill in a four point suspension, but they also function as stop means to lock and prevent outward spreading of the grill assembly.
In some instances, it is desirable to protect grill assembly 4 from the wind during cooking. For this purpose, and as shown in FIGS. 9-11, a wind guard 22 of glass cloth or other suitable fire resistant material is provided. In the present embodiment, guard 22 is trapezoidal (FIG. 9) and may be suitably folded along seams 23. When it is desired to protect one lower side of the cooking apparatus, guard 22 is extended between the lower ends of two tripod legs (FIG. 10) and wrapped around them and secured in any suitable well-known way, such as by snaps, not shown. Guard 22 is dimensioned so that if it is desired to protect all sides of the apex portion of the tripod, it can be wrapped around all three sides between the legs (FIG. 11) and also secured in any suitable well-known way to retain heat and smoke.
At times, it may be desired to include a drip pan or other grill-like device beneath grill assembly 4. As shown in FIG. 12, a drip pan assembly 24 is disposed on the apparatus and may be generally similar to assembly 4, except for being larger so that its support cables 25 don't interfere with cables 5.
When the entire device is disassembled for transportation or storage, all of the elements thereof may be inserted into large tripod leg 2. For this purpose, the diameter of small legs 1 are such that the latter will fill less than half the diameter of tubular leg 2; and grill channel members 12, when placed in facing relationship with rods 18 between them, will fill the remaining portion of leg 2. See FIG. 14.
As shown in FIG. 13, the members are slid into leg 2 until legs 1 hit lip 8, which acts as an integral stop at one end. A suitable holding cap 26 is placed on the opposite end of leg 2.
The tripod cooking device of the present invention is easy to assemble, disassemble and store; and is relatively inexpensive to manufacture.
Various modes of carrying out the invention are contemplated as being within the scope of the following claims particularly pointing out and distinctly claiming the subject matter which is regarded as the invention.
