~z~a~
Il~ustrated in Figures 1-4 i5 a convertible cooking unit 10 embodying the present invention in the compact ~,ode :for st,cra(3e and transporting. To~:ard this end, the convert,ible cooXi.ng unit 10 coinprises an oven 15 made, in the preferred er~ Qcliment, of stainless steel.
The oven ]5 inc~udes a suitable stainl--ss steel dr.l~:er 16. At the rear wall 17 of the oven 15 is a suit:c~ble opening 18. At the ~ear wall of t}-e dl:a~ier 16 is a yieldable la1ch ]9~ ~hen i-he latch 1,9 ellgages the rear ~all 17 surrounding the opening 18, the drawer 16 is retained in the closc,~d L~os;tion wit-l-;n the oven 15.
n the latch l9 is urged a~ay fl-om t,he rcar wall 17 against its yieldable action, the drawer ]6 is moved manually to an open position or a positi,on extending forwardly of a :rront wall 20 of the oven 15.
On the front wall 24 of the drawer 1.6 of the oven 15 is a handle'25 which is sw;,ngably Inounted on the front wall 24 by suitabl.e ears 26. rrhe ears 26 are attached to the front wall 24.
Upstanding from a top wall 30 of the oven 15 al.ong the peri.meter thereof are four upstanding flanges 31 in a quadrilateral relation. D;,sposed above the oven 15, when the convertible cooki,ng unit 10 is in the compact mode, ;s a suitable large flat grill 35 (Figure 4). The large grill 35 includes parallel longi1ud;nal rows of openiilgs 36 spaced equal distances apart i-n the transverse direction. The grill 35, in the preerred elnhc>cii,mcnt~ is made of stainless steel.
~hove the larae grill 35 is dispcsed a folded windbreak 40 made/ in the preferred embodiment, of ~.~Z~i88~3 st:ainless stfeel, In the preferred ernbodimentl the windbreak 40 includes thrfe panels 41-43 to form in the extfnaed po~,ition upright panels 41--~3 defi.ning a rear and adjacellt sides. 'rhe side panels 47 and 42 are hingedly attached to opposite ellds of Lhe rear panel 43 (Figure -7). Tn ~;nd blow;ng areas, t:he ~-~indbrea~ 40 reduces hfat loss during t:he cook;ng operati.on. Toward this end, a blast of willd ~lollld have a lesser tell~ n~cy to blow ht-~at fl-om the cook-ing ~aurf(~ce t-hat would genera].ly he utili~,ed for coo~ing pul-poSes. Tile oyening l~c~t~een l-he ~ide panel.s 41 and 42 would gell(?rally face the dirf.~ction in which the wi.nd blows.
Disposed on the top of the wi.ndbreak ~0 and an xpcsf.~d secti.on of the large yrill is a griddle or sauce pan 50. The griddle 50 is a flat member of preferably stain].ess steel with upstanding flanges around the per;meter thereof to form a quadril,ateral confi.guration.
~rhe griddle 50 can lnterchangeably be used in lieu of the l.arge gril.l 35 for performing various coo~ing ~0 procedllres.
A diffuser 55 is disposed on tl-e griddle SO and has a quadrilateral configuration. The diffuser 55 is a flat mem.ber made, in the preferred c~mbodiTnent, of stainless stcel with opc-ni.ngs 56 formed in the vicinity of the siaes thereof, but inwardly of the edges thereof.
The openings 56 define a quadril.ateral configuration.
The diffuser 55 serves to di.stribute heat from a concentrated or localized source unjfol-mly or c-venly throughout a brGader area or coo~ing surface, such as t,he sriddle 50 or the large grill 35.
~Z~38~
In the compact mode, a folded or collapsed truncated pyramidal support merrber 60 is disposed on one secti.on of the diffuser 55. rhe truncated pyra~idal support ~ember 60 comprises, in the preferred cmbodi~ent, six st-a;nless steel panels 61--66. ,-djacent panels 61 and 62 are il;nycd togethcr t:o form a trullcated panel, ~.hen extended. CGIlfronti3lg adjacent panels 63 and 64 are h;llged together and form a truncated pan~ 1hen extel-dc?d.
~anels 65 and 66 are truncated panels fo.rmed with suitab].e open;ngs for venting of heat ar,d the conduction of air. The panel 65 is hinged at its opposite ellds to pane].s 62 and 64, respectively. Similarly, the panel 66 ;.s hi.n~3ed at its opposi.te ends to panels 61 and 63, respectivel~. In the extel-ded or unfo]ded condition for use during a cooking operation, the support member 60 assumes a truncated pyra~idal configuration. To fold the support memher 60 for the compact mode, the panels 61, 62 and 63, 64 are folded along t:heir resp~ctive h;nge connections in~ardly (Figure 3) for placement on a section of the di.ffuser 55.
The extended or unfolded truncated pyramidal support member not only supports a cooking surface, such as the griddle 50 or the large grill 35, but also conducts the heat so as to apply the heat over a broader cooking s~rface, such as t.he griddle 50 or the large grill 35.
A folded or collapsed truncated pyramidal firebox 70 is disposed on a section of the diffuser 55 for the storage and transport COm.paCt mode. There will be a slight overlapping re]a~ion bet~een the folded truncated pyramidal firebox 70 and the folded trùncated pyramidal 3L2~L8~3 support member 65 i.n t}-~e compact mc)de, in the exemplary embodiment. The t:runcated pyramidal firebox 70, in.
the preferred elrbodiment, is made of stainless steel and compr;ses paTlels 71--76 (Figure 61. ~djacent panels 71 and 72 are hinged together to form a trllncated panel when ext~-nQed. Confront-;ng adjacent pànels 73 and 74 are hinged together to fol:m a trllncatc-d panel, when extended. Pane1s 75 an~ 76 (Figure 8) are truncated panels. ~rhe panel 75 is llinged at its opposite ends to panels 72 and 74, respectively. Simi~.arly~ the panel 76 is h;.nyed at its opposi.te ends to panels 71 and -73, re pectively. Tn the e~tend(~d or unfolded condition, the firebox 70 assul~es a truncated pyramidal confi(3ul-at;on so as to be suitable for use during a cooking operation (Fiyure 1). rO fold the firebox 70 for the compact mode, the panels 71, 72 and 73, 74 are folded al.ong their respective hinged connections in~-7ardly (Figure 3) for placement on a section of the diffuser 55.
Fuel is placed in the firebox 70 on the top wa]l.
30 of the oven 15, when extended for cooking operations, to generate the heat for cooking operations (Figure 2).
The truncated pyramidal configuration of the firebox 70 serves to concentrate or convc-rge the generated heat and to di.rect or focus the heat on a cooking surface.
~;naedly att:ached to the panel 75 at the top thereof is a small grill 80. The small grill 80 when folded over the top of tile firebox 70, ~hen extended, forrns a cooXing .s~riace. ~.hen pivoted away from the central opening throuyh the eY.tenQed firebox 70, the small grill 80 ~Z~388 rests against the panel 75 to provide a yreater access area for the circulation of heat and air through the extended firebox tO. I~ingedly (Ittached to t.he panel 76 at the bottom ther~of is a damper or access door 81.
~rhe damper or access door 81, ~hen disposed against the panel 76, covers an access opening 82 formed in the panel 76. For increasing the circulation of air through the opening 82, the damper 81 is pi.voted about its horizontally dispo ed hi.nye away from the panel 76, thereby enabl.ing the increase of fl.ow of air through the open;ng 82 of the f;rebox 70. Fuel may be pl.a~ed w;tilin t~ e firebox 70 through the access opening 82.
A halldle 83 is journalled for rotation on the da~.per 81 through ears 84. By gri.pping the handle 83, the damper 8l can be moved about the horizontally disposed hinge at the l:ower end of the panel 76. A
cylindrical opening 85 is fol~med in the damper 81.
Attached to the handle 83 for rotatable movement there-with is a aisc 86. The disc serves to regulate the exposure of the opening 85 for controlling the circllla-tion of air through the opening 85. Thus, the disc 86 also functions as a dar~per, when the damper 81 covers the access opening 82.
A cover 100 (Figure S) is disposed above the firebox 70 and the support member 60 during the compact mode.
~epending flang~s 101 (Figure 4) form a quadrilateral configuration and extend out~ardly and alongside the upstar,dirg flanges 31 of the oven 15 during the compact l?ode. Fi ed to the top ~:all of the cover 100 is a flexibl.e latch 102 that has a lower angular member 103 8~3 to grip the front upstanding flange 31 of the oven 15 to releasably secure or lock the cover 100 to the oven l5. In this manner, a COmpact cooking unit 10 is provided for StGraye and for transportation (Figures 1 and 2). The rear depending flange 101 of the cover l.00 ;nclucies a li.p or c]-annel sihaped member along ;ts lcwer edge. The ~ip or channel shaped rramber is retained in a ch.lnnel shaped edge along the rear up-st:anding flange 31 of the oven 15. In th;s manner, the rear of the cover 100 is rel~asably secured and pivotally connc~cted to the rear of l:he oven 15.
To asscml~le the conveît-ible cooking unit 10 for a cooking operati.on, the free end of the f]exible l.atch ]02 ;s moved away from the upstanding front flange 31 of the oven 15 to free itself from locking engagement tllerewith. The cover 100 is lifted in pivotal manner about the lip on the Lear depending flange 101 thereof (Figure 3). The cover lO0 is now moved forwardly to release the lip at the rear thel-eof from the oven 15.
rO secure the cover 100 to the oven 15, the lip at the rear thereof is p].aced in the channel shaped edge along the rear upstand;ng flange 31 of the oven 15 to be reta;.ned therein (Figure 5). The cover 100 is pivoted downwardly about the rear lip thereof until the latch 102 grips the upstanding front flange 31 of the oven 1.5 to be retained thereby. ~hen the flanges 101 extend ao~-;nwardly, the cover 100 rnay be used as a flat griddle.
.i-,en the flanoes 101 extend upw.2rdly, the cover 100 rr.ay be fn-lployed as a sauce pan.
In the use of the convertible cooking unit 10 for various cooking procedures, referer,ce is made to Figures 6-16~ The oven 15 forms the hase of the convertible cooking unit 10 ;n Figures 8 and 9. The firebox 70 is un~olded or e~t~ndrd and is d;sposed on the top wall 30 of the oven 15 be~ een the upst-anding flanges 31 i-hereof. The slllall ~rill 80 ;s pivoted to co~-er the central opening through t:lne t{uncat:ed pyr midal fil-ebox 70. Fuel is p].aced in the firebox 70 on top of t.he t:op ~-all 30 of the oven 15 to gencrate the heat for cooXing.
The convertible cookiny unit~ as illustrated ;n Figures 6, 10 and 1.1, provides for the oven 15 and the ]ar~e grill 35. Aga;n, tlle oven 15 fol-ms tlle base of the convel-t;ble cooking unit 10. As previously des-cribed, the firebox 70 is unfolded or extended and is lS disposed on the top wall 30 of the oven 15 between the upstanding flanges 31 thereof. The small grill 80 is again pivoted to cover t21e central open;.ng of the truncated pyramidal firebox 70. At t:l-is t;me, the support rnember 60 is unfolded or extended to assu~e a truncated pyramidal configuration. The truncated pyrarriidal support member 60 is placed on the firebox 70 with the narrow opening thereof at the bottom t2-lereof. The c-xtended firebox 70 and the extended support member 60 are ali~ned axially with tile narrow end of the firebox 70 received by the narrow end of the support mc-mber 60. rhus, the p~rarnidal support member 60 is inverted ~ith respect to the pyramidal firebox 70~ ~rhe diffuser 55 is now disposed in the truncated pyrarridal. support member 6Q and is hor;.~ontally disposed.
~rhe ]arge yril.l 35 is disposed on the truncated l~Z~ ~38 pyramidal Support rnem.ber 60.
In ~he alternative, the griddle SO can be used in lieu of the large grill 35 (F;yure 12). If desired, the cover lOO may be empl.oyed as d gr;ddle and used ;.n lieu of the g~iddle 50 (Figure 7).
In Figures 13-~5, the con~ertible cooking unit 10 providcs ~or the oven 15 io be disposcd at the top of the cooking unit 10. T`ne cover 100 is emp~.oyed as t:he base of the cooking unit 10. I~cnce, the flange-s 101 of the cover 100 are now upstanding. The fi.rebox 70 is d;sposea on tnc over lOO within the nE~standing ~1angcs lOl t-hercof. Tn turn, the truncated pyralnidal support m~-JI~er 60 is placed on the f;.rebox 70 with t.he narrow ~nd thereof rc-ceiving the firebox 70. D;sposed within the truncatcd pyramidal support member 60 is the dif~user 55. Now, the drawer 16 is removed from the oven 15. The oven 15 is disposed on the truncated ~yramidal support member 60 with the flanges 101 thereof dcpending and surrounding the top of the panels 61-66 of the support mcmber 60. The dl-awer 16 is reinsel.ted into the oven 15.
The cooking unit 10 as illustrated in Figure 16 is similar to the cooking unit 10 illustra~ed in Figule 12. In Figure 16, the windbreak 40 is employed to conserve the heat applied to 1he cooking surface, such as thc griddle 50. For addcd protect:ion against wc-ather elements, the cover 100 can be disposed on the wi.ndbrcak 40 to provide an o~erhcad horizontal prot~.ct;ng wall.
To inpLove the versatility of the cooking unit, an oven ~ith a dr2~:er is plovided. ~rhe collapsed or '~4 ``

Il~ustrated in Figures 1-4 i5 a convertible cooking unit 10 embodying the present invention in the compact ~,ode :for st,cra(3e and transporting. To~:ard this end, the convert,ible cooXi.ng unit 10 coinprises an oven 15 made, in the preferred er~ Qcliment, of stainless steel.
The oven ]5 inc~udes a suitable stainl--ss steel dr.l~:er 16. At the rear wall 17 of the oven 15 is a suit:c~ble opening 18. At the ~ear wall of t}-e dl:a~ier 16 is a yieldable la1ch ]9~ ~hen i-he latch 1,9 ellgages the rear ~all 17 surrounding the opening 18, the drawer 16 is retained in the closc,~d L~os;tion wit-l-;n the oven 15.
n the latch l9 is urged a~ay fl-om t,he rcar wall 17 against its yieldable action, the drawer ]6 is moved manually to an open position or a positi,on extending forwardly of a :rront wall 20 of the oven 15.
On the front wall 24 of the drawer 1.6 of the oven 15 is a handle'25 which is sw;,ngably Inounted on the front wall 24 by suitabl.e ears 26. rrhe ears 26 are attached to the front wall 24.
Upstanding from a top wall 30 of the oven 15 al.ong the peri.meter thereof are four upstanding flanges 31 in a quadrilateral relation. D;,sposed above the oven 15, when the convertible cooki,ng unit 10 is in the compact mode, ;s a suitable large flat grill 35 (Figure 4). The large grill 35 includes parallel longi1ud;nal rows of openiilgs 36 spaced equal distances apart i-n the transverse direction. The grill 35, in the preerred elnhc>cii,mcnt~ is made of stainless steel.
~hove the larae grill 35 is dispcsed a folded windbreak 40 made/ in the preferred embodiment, of ~.~Z~i88~3 st:ainless stfeel, In the preferred ernbodimentl the windbreak 40 includes thrfe panels 41-43 to form in the extfnaed po~,ition upright panels 41--~3 defi.ning a rear and adjacellt sides. 'rhe side panels 47 and 42 are hingedly attached to opposite ellds of Lhe rear panel 43 (Figure -7). Tn ~;nd blow;ng areas, t:he ~-~indbrea~ 40 reduces hfat loss during t:he cook;ng operati.on. Toward this end, a blast of willd ~lollld have a lesser tell~ n~cy to blow ht-~at fl-om the cook-ing ~aurf(~ce t-hat would genera].ly he utili~,ed for coo~ing pul-poSes. Tile oyening l~c~t~een l-he ~ide panel.s 41 and 42 would gell(?rally face the dirf.~ction in which the wi.nd blows.
Disposed on the top of the wi.ndbreak ~0 and an xpcsf.~d secti.on of the large yrill is a griddle or sauce pan 50. The griddle 50 is a flat member of preferably stain].ess steel with upstanding flanges around the per;meter thereof to form a quadril,ateral confi.guration.
~rhe griddle 50 can lnterchangeably be used in lieu of the l.arge gril.l 35 for performing various coo~ing ~0 procedllres.
A diffuser 55 is disposed on tl-e griddle SO and has a quadrilateral configuration. The diffuser 55 is a flat mem.ber made, in the preferred c~mbodiTnent, of stainless stcel with opc-ni.ngs 56 formed in the vicinity of the siaes thereof, but inwardly of the edges thereof.
The openings 56 define a quadril.ateral configuration.
The diffuser 55 serves to di.stribute heat from a concentrated or localized source unjfol-mly or c-venly throughout a brGader area or coo~ing surface, such as t,he sriddle 50 or the large grill 35.
~Z~38~
In the compact mode, a folded or collapsed truncated pyramidal support merrber 60 is disposed on one secti.on of the diffuser 55. rhe truncated pyra~idal support ~ember 60 comprises, in the preferred cmbodi~ent, six st-a;nless steel panels 61--66. ,-djacent panels 61 and 62 are il;nycd togethcr t:o form a trullcated panel, ~.hen extended. CGIlfronti3lg adjacent panels 63 and 64 are h;llged together and form a truncated pan~ 1hen extel-dc?d.
~anels 65 and 66 are truncated panels fo.rmed with suitab].e open;ngs for venting of heat ar,d the conduction of air. The panel 65 is hinged at its opposite ellds to pane].s 62 and 64, respectively. Similarly, the panel 66 ;.s hi.n~3ed at its opposi.te ends to panels 61 and 63, respectivel~. In the extel-ded or unfo]ded condition for use during a cooking operation, the support member 60 assumes a truncated pyra~idal configuration. To fold the support memher 60 for the compact mode, the panels 61, 62 and 63, 64 are folded along t:heir resp~ctive h;nge connections in~ardly (Figure 3) for placement on a section of the di.ffuser 55.
The extended or unfolded truncated pyramidal support member not only supports a cooking surface, such as the griddle 50 or the large grill 35, but also conducts the heat so as to apply the heat over a broader cooking s~rface, such as t.he griddle 50 or the large grill 35.
A folded or collapsed truncated pyramidal firebox 70 is disposed on a section of the diffuser 55 for the storage and transport COm.paCt mode. There will be a slight overlapping re]a~ion bet~een the folded truncated pyramidal firebox 70 and the folded trùncated pyramidal 3L2~L8~3 support member 65 i.n t}-~e compact mc)de, in the exemplary embodiment. The t:runcated pyramidal firebox 70, in.
the preferred elrbodiment, is made of stainless steel and compr;ses paTlels 71--76 (Figure 61. ~djacent panels 71 and 72 are hinged together to form a trllncated panel when ext~-nQed. Confront-;ng adjacent pànels 73 and 74 are hinged together to fol:m a trllncatc-d panel, when extended. Pane1s 75 an~ 76 (Figure 8) are truncated panels. ~rhe panel 75 is llinged at its opposite ends to panels 72 and 74, respectively. Simi~.arly~ the panel 76 is h;.nyed at its opposi.te ends to panels 71 and -73, re pectively. Tn the e~tend(~d or unfolded condition, the firebox 70 assul~es a truncated pyramidal confi(3ul-at;on so as to be suitable for use during a cooking operation (Fiyure 1). rO fold the firebox 70 for the compact mode, the panels 71, 72 and 73, 74 are folded al.ong their respective hinged connections in~-7ardly (Figure 3) for placement on a section of the diffuser 55.
Fuel is placed in the firebox 70 on the top wa]l.
30 of the oven 15, when extended for cooking operations, to generate the heat for cooking operations (Figure 2).
The truncated pyramidal configuration of the firebox 70 serves to concentrate or convc-rge the generated heat and to di.rect or focus the heat on a cooking surface.
~;naedly att:ached to the panel 75 at the top thereof is a small grill 80. The small grill 80 when folded over the top of tile firebox 70, ~hen extended, forrns a cooXing .s~riace. ~.hen pivoted away from the central opening throuyh the eY.tenQed firebox 70, the small grill 80 ~Z~388 rests against the panel 75 to provide a yreater access area for the circulation of heat and air through the extended firebox tO. I~ingedly (Ittached to t.he panel 76 at the bottom ther~of is a damper or access door 81.
~rhe damper or access door 81, ~hen disposed against the panel 76, covers an access opening 82 formed in the panel 76. For increasing the circulation of air through the opening 82, the damper 81 is pi.voted about its horizontally dispo ed hi.nye away from the panel 76, thereby enabl.ing the increase of fl.ow of air through the open;ng 82 of the f;rebox 70. Fuel may be pl.a~ed w;tilin t~ e firebox 70 through the access opening 82.
A halldle 83 is journalled for rotation on the da~.per 81 through ears 84. By gri.pping the handle 83, the damper 8l can be moved about the horizontally disposed hinge at the l:ower end of the panel 76. A
cylindrical opening 85 is fol~med in the damper 81.
Attached to the handle 83 for rotatable movement there-with is a aisc 86. The disc serves to regulate the exposure of the opening 85 for controlling the circllla-tion of air through the opening 85. Thus, the disc 86 also functions as a dar~per, when the damper 81 covers the access opening 82.
A cover 100 (Figure S) is disposed above the firebox 70 and the support member 60 during the compact mode.
~epending flang~s 101 (Figure 4) form a quadrilateral configuration and extend out~ardly and alongside the upstar,dirg flanges 31 of the oven 15 during the compact l?ode. Fi ed to the top ~:all of the cover 100 is a flexibl.e latch 102 that has a lower angular member 103 8~3 to grip the front upstanding flange 31 of the oven 15 to releasably secure or lock the cover 100 to the oven l5. In this manner, a COmpact cooking unit 10 is provided for StGraye and for transportation (Figures 1 and 2). The rear depending flange 101 of the cover l.00 ;nclucies a li.p or c]-annel sihaped member along ;ts lcwer edge. The ~ip or channel shaped rramber is retained in a ch.lnnel shaped edge along the rear up-st:anding flange 31 of the oven 15. In th;s manner, the rear of the cover 100 is rel~asably secured and pivotally connc~cted to the rear of l:he oven 15.
To asscml~le the conveît-ible cooking unit 10 for a cooking operati.on, the free end of the f]exible l.atch ]02 ;s moved away from the upstanding front flange 31 of the oven 15 to free itself from locking engagement tllerewith. The cover 100 is lifted in pivotal manner about the lip on the Lear depending flange 101 thereof (Figure 3). The cover lO0 is now moved forwardly to release the lip at the rear thel-eof from the oven 15.
rO secure the cover 100 to the oven 15, the lip at the rear thereof is p].aced in the channel shaped edge along the rear upstand;ng flange 31 of the oven 15 to be reta;.ned therein (Figure 5). The cover 100 is pivoted downwardly about the rear lip thereof until the latch 102 grips the upstanding front flange 31 of the oven 1.5 to be retained thereby. ~hen the flanges 101 extend ao~-;nwardly, the cover 100 rnay be used as a flat griddle.
.i-,en the flanoes 101 extend upw.2rdly, the cover 100 rr.ay be fn-lployed as a sauce pan.
In the use of the convertible cooking unit 10 for various cooking procedures, referer,ce is made to Figures 6-16~ The oven 15 forms the hase of the convertible cooking unit 10 ;n Figures 8 and 9. The firebox 70 is un~olded or e~t~ndrd and is d;sposed on the top wall 30 of the oven 15 be~ een the upst-anding flanges 31 i-hereof. The slllall ~rill 80 ;s pivoted to co~-er the central opening through t:lne t{uncat:ed pyr midal fil-ebox 70. Fuel is p].aced in the firebox 70 on top of t.he t:op ~-all 30 of the oven 15 to gencrate the heat for cooXing.
The convertible cookiny unit~ as illustrated ;n Figures 6, 10 and 1.1, provides for the oven 15 and the ]ar~e grill 35. Aga;n, tlle oven 15 fol-ms tlle base of the convel-t;ble cooking unit 10. As previously des-cribed, the firebox 70 is unfolded or extended and is lS disposed on the top wall 30 of the oven 15 between the upstanding flanges 31 thereof. The small grill 80 is again pivoted to cover t21e central open;.ng of the truncated pyramidal firebox 70. At t:l-is t;me, the support rnember 60 is unfolded or extended to assu~e a truncated pyramidal configuration. The truncated pyrarriidal support member 60 is placed on the firebox 70 with the narrow opening thereof at the bottom t2-lereof. The c-xtended firebox 70 and the extended support member 60 are ali~ned axially with tile narrow end of the firebox 70 received by the narrow end of the support mc-mber 60. rhus, the p~rarnidal support member 60 is inverted ~ith respect to the pyramidal firebox 70~ ~rhe diffuser 55 is now disposed in the truncated pyrarridal. support member 6Q and is hor;.~ontally disposed.
~rhe ]arge yril.l 35 is disposed on the truncated l~Z~ ~38 pyramidal Support rnem.ber 60.
In ~he alternative, the griddle SO can be used in lieu of the large grill 35 (F;yure 12). If desired, the cover lOO may be empl.oyed as d gr;ddle and used ;.n lieu of the g~iddle 50 (Figure 7).
In Figures 13-~5, the con~ertible cooking unit 10 providcs ~or the oven 15 io be disposcd at the top of the cooking unit 10. T`ne cover 100 is emp~.oyed as t:he base of the cooking unit 10. I~cnce, the flange-s 101 of the cover 100 are now upstanding. The fi.rebox 70 is d;sposea on tnc over lOO within the nE~standing ~1angcs lOl t-hercof. Tn turn, the truncated pyralnidal support m~-JI~er 60 is placed on the f;.rebox 70 with t.he narrow ~nd thereof rc-ceiving the firebox 70. D;sposed within the truncatcd pyramidal support member 60 is the dif~user 55. Now, the drawer 16 is removed from the oven 15. The oven 15 is disposed on the truncated ~yramidal support member 60 with the flanges 101 thereof dcpending and surrounding the top of the panels 61-66 of the support mcmber 60.
