invention. relates to improvements in ee n w k rids- U The main objects oi thisinvention are;

Fir'st,- toprovide aknockdown cooking grid,-

' vantages which may bereadily set up or knocked down and one in which the parts, when. set up, are: effectively retained inassembledrelation. I

Objects relating to details and economies of the invention will appear-from the description to follow. The invention is defined and pointed out in the claims.-

referred embodiments of the. invention are illustrated in the accompanying drawing, in which: N

Fig.- 1 is a perspective view of my cooking grid in fully erected or assembled condition.

Fig. 2 isan enlarged plan view of one of the grid top sections.

Fig. 3 is an enlarged fragmentary view of one of the leg members.

Fig. 4 is a fragmentary View of one of the coupling and supporting rods.

Fig. 5 is an enlarged fragmentary section on line 5-5 of Fig. 2 showing certain of the structural details.

Fig. 6 is a perspective view of a packaged grid in' t'he' knockdown, that is, with the parts enclosed in a wrapper 61" case.

Fig. '7 is a fragmentary perspective view of a modified form or embodiment of my invention in which the leg members constitute means for preventing relative movement of the grid sections when they are assembled with the supporting rods.

The structure illustrated in the accompanying drawing is designed for general use as an out-ofdoor cooking grid and at the same time one that is quite light in weight so that it may be conveniently carried.

The grid comprises a plurality of grid top sections designated by the numerals l, l, I, there being three sections in the structure illustrated. Each grid section comprises a plurality of grid bars 2 arranged in spaced parallel relation and fixedly secured to the cross bars 3 preferably by welding as shown at 4 in Fig. 5.

It will be noted that the ends of the cross bars project at each and beyond the outer side grid bars. The gridbarsare preferably formed of wire stock of fiat section and present a desirable top surface to the grid.

The grid bars terminate in downturned eyes 5', the eyes of the several sections" being aligned when the sections are assembled to" receive the coupling and supporting ro'd's ii which are formed of wire or light rod stock and terminate in loops 1 at one end which constitute finger pieces".

As the ends of the cross bars or the sections project at each end, the sections may be as: sembl'ed in any relation to each other and the grid bars" of adjacent sections are propen spaced.

I provide a pair of leg members designated enerally by the. numerai 8', each comprising a pair of laterally spaced legs 9 connected by the cross bars H!- as rigid units, the cross bar's being welded to the legs or otherwise rigidly secured thereto. The legs 9 terminate in eyes II at their upper ends, receiving thecouplingrod and thereby connecting the leg members to the grid top. Inasmuch as the eyes of the leg members are between adjacent grid bars the legs may be properly positioned and are retained in proper position in assembled relation. I

In Fig. '7, the fees of the leg members are spaced so that the eyes are disposed between grid bars of the outer grid sections thereby preventing separation of the grid section while the coupling itid's and legs are" assembled therewith. White this feature is advantageous from the standpoint of locking the s'e'ctilinsin assembled relationthat is, preventing the sections from any separa' rating movement on the rods, the wider legmembers increase the width of the knock-down stacked assembly.

In the embodiment shown in Figs. 1, 2 and 3, the leg members are of the same width as the grid sections which it will be appreciated is a feature of some advantage in the matter of compactness. However, the knockdown stacked parts are relatively compact in either case. If desired, the leg members may be collapsed on the under side of the grid top.

In Fig. 6, I illustrate a case or package l2 which may be wrapped around the stacked parts. It is shown as provided with a binding l3 for the edges of the flexible case, these terminating in tie strings I4.

The structure may be readily and compactly collapsed so that when knocked down, or after use, it may be packed in an envelope or bag without the necessity of cleaning and then may be handled without soiling the hands or other articles with which it might come in contact unless enclosed. The lower cross bars ii] are preferably so spaced from the ends of the legs that they serve as stops limiting the penetration of the legs in the ground and prevent the legs from going too far into the ground thereby keeping the cooking grill level. If the ground is soft, the cross bar prevents sinking into soft ground when a heavy load is placed on the grill and prevents the tilting of the grill under load.

I have illustrated and described my invention in a commercial embodiment thereof which I have found very satisfactory. I have not attempted to illustrate or describe other modifications or adaptations in details as it is believed that this disclosure will enable those skilled in the art to embody or adapt my invention as may be desired.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. A knockdown cooking grid comprising a plurality of like grid top sections, each comprising cross bars and a plurality of grid bars secured to the tops thereof in spaced parallel relation with the ends of the cross bars projecting beyond the outer grid bars of the sections, said grid bars having downturned eyes at the ends thereof, coupling and supporting rods removably disposed through the eyes of the grid bars with the sections arranged in edge to edge relation with the ends of cross bars of adjacent sections in abutting relation to space the end grid bars of adjacent sections, and leg members comprising later" ally spaced legs and connecting cross bars therefor, the legs being provided with eyes receiving said coupling and supporting rods, said legs being spaced so that the leg members are of substantially the width of the grid sections permitting the stacking thereof with the grid sections when the structure is disassembled.

2. A knockdown cooking grid comprising plurality of grid top sections, each comprising cross bars and a plurality of grid bars secured to the tops thereof in spaced parallel relation with the ends of the cross bars projecting beyond the outer grid bars of the sections, said grid bars having downturned eyes at the ends thereof, coupling and supporting rods removably disposed through the eyes of the grid bars with the sections arranged in edge to edge relation with the ends of cross bars of adjacent sections in abutting relation to space the end grid bars of adjacent sections, the cross bars projecting at each end from their associated grid section to permit the sections being arranged in any order relative to each other, and leg members comprising laterally spaced legs and connecting cross bars therefor, the legs being provided with eyes receiving said coupling and supporting rods.

3. A knockdown cooking grid comprising a plurality of grid top sections, each comprising cross bars and a plurality of grid bars secured thereto in spaced parallel relation, said grid bars having eyes at the ends thereof, coupling and supporting rods removably disposed through the eyes of the grid bars with the sections arranged in edge to edge relation, and leg members comprising legs connected in spaced relation and provided with eyes receiving said coupling and supporting rods.

4. A knockdown cooking grid comprising a plurality of grid top sections, each comprising cross bars and a plurality of grid bars secured thereto in spaced parallel relation, said grid bars having eyes at the ends thereof, coupling and supporting rods removably disposed through the eyes of the grid bars with the sections arranged in edge to edge relation, and leg members comprising legs and connecting cross bars therefor whereby the leg members constitute assembled units, the legs being provided with eyes at their upper ends re ceiving said coupling and supporting rods, the lower cross bars being spaced from the ends of the legs to constitute ground engaging members.

5. A knockdown cooking grid comprising a plurality of like grid top sections, each section comprising cross bars and a plurality of grid bars secured thereto in spaced parallel relation, said grid bars having eyes at their ends, coupling and supporting rods adapted to be passed through the eyes of the grid bars with the sections arranged in side by side relation for joining said sections and supporting said sections one from the other, and a pair of leg members comprising legs connected in spaced relation and provided with eyes at the upper ends thereof adapted to receive said rods when said rods are passed through said grid sections for supporting said rods and sections on said leg member.
