Abstract

A portable grill device comprises a firebox which has a hexagonal plan form and six side walls and is made of sheet steel and of even height and is provided with at least three detachable legs, a vertically adjustable cooking grid and a pot-holder that pivots on a vertical axis. In the corners of each of the side walls inwardly bent lug sheets are arranged together which with the corner sections of the side walls form connector lugs open at the top and bottom and having a rhombic cross section. Into these connector lugs, rhombic connecting pegs of the legs can be inserted form-fittingly from the bottom side of the firebox, and from the top, either connecting pegs of wind-guard walls or additional legs can be inserted to form a girder-like kettle or grid hanging device, or pot-holders. Each of the legs comprise metal tubes at one end have a connecting peg with rhombic cross-section, bent by 30°. The mountable wind-guard walls are joined to each other in a hinge-like manner, with the hinge spindles at the same time forming connecting pegs.

Claims

1. A portable grill device, comprising a firebox having six upright side walls which are connected to each other at adjacent corners disposed as angles to each other to form a hexagon, a bent lug sheet extending upwardly over substantially the same height as each side wall located in the vicinity of each corner and being being fixed to inner surfaces of the side walls at each corner, each lug sheet defining with a respective corner, a connector recess eye which is open at the top of said firebox, each connector eye having a rhombic cross-section, a plurality of legs for selective ones of said connector eyes, each leg having one end with a support leg portion and an opposite end with a connecting leg portion of substantially rhombic form for non-rotatable engagement in one of said connector eyes, each leg having a straight portion which is bent at an acute angle to said connecting peg portion, limiting means engaged between each leg and each connector eye for limiting the depth of penetration of each peg portion into each eye, and a plurality of support elements selectively engageable into the open top of ones of said connector eyes for supporting at least one of a wind guard wall, a grid and a potholder.

2. A portable grill according to claim 1, wherein there are at least three detachable legs and including a removable wind guard wall in said support elements engaged in the eyes from the tops thereof supporting said wind guard walls.

3. A portable grill according to claim 2, including a pot holder including a rod portion engageable in one eyes and an arm portion having a circular opening therein for a pot extending outwardly from the arm portion and being pivotable with said arm portion in the recess, and including a cooking grid and means for supporting said cooking grid in said wind guard wall.

4. A portable grill according to claim 2, wherein said legs also include angular base portions at the end thereof opposite to said connecting peg portions extending substantially parallel to said connecting peg portions.

5. A portable grill according to claim 1, including a plurality of wind guard walls each having a length equal to the length of the side walls of said firebox, said wind guard walls have end formations at each end thereof and including a hinge joint pivotably connecting said guard walls together, said hinge joint being long enough to engage into the recess eye of said firebox walls to support said wind guard walls above corresponding firebox walls.

6. A portable grill according to claim 5, wherein said hinge joints comprise spindle elements, said wind guards having hinge eyelets through which said spindle elements engage.

7. A portable grill according to claim 1, wherein each of said recess eyes has a gate support piece therein intermediate the height of said eye which runs parallel to the longitudinal axis of the eye.

8. A portable grill according to claim 7, including a plurality of pot holders each including a rectangularly bent round bar having a leg portion rotatably supported in the recess eye and have an outer end offset from the bar with means for suporting a pot thereon.

9. A portable grill according to claim 1, including braziers having a trapazoidal cross-section with a base side comprising a perforated metal sheet and with other side wall sections forming closed areas having only a few small openings, said braziers being of a size to be randomly placed in the firebox.

10. A portable grill according to claim 9, wherein two wall elements of said fire limiter are dissimilarly long in a ratio of approximately 1.2:

1 up to 2;

1.

11. A portable grill according to claim 1, including a plurality of wind guard walls, a rod member between each of said guard walls pivotably supporting one guard wall with the other, said guard walls extending entirely around the firebox and including a cover over the top of said guard walls so as to form a smoking chamber within said firebox.

12. A portable grill according to claim 1, including at least two substantially similarly shaped fire limiters arranged randomly in the firebox, each comprising two connected oblong wall elements with parallel longitudinal edges, said fire limiters forming an angle of from 90°

to 120°

with each other and both are being inclined outwardly in relation to the vertical by an angle of about from 20°

to 30° and

having outer ends in the vicinity of the common vortex which have bases at least 0.5 cm in height.

13. A portable grill according to claim 1, including a plurality of wind guard walls overlying each of the side walls and extending upright above said side walls and each being provided with a vertical slot having slotted lugs at graduated heights to hold horizontal cotter pins, and a cooking grid holder plate supported on said wind guard walls, said wind guard walls being provided with a horizontal slot ending in a vertical slot in which the cotter pins are engaged and which hold said cooking grid.

14. A portable grill according to claim 1, wherein said acute angle is approximately 30°

.

15. A portable grill according to claim 1, wherein said limiting means comprises an angular portion connected to said straight portion at said acute angle, said connecting peg portion being connected to said angular portion, said angular portion defining a shoulder at said connecting peg portion for engagement against said firebox with said peg portion engaged into one of said eyes for limiting the depth of penetration of said peg portion in said one eye.

16. A portable grill device, comprising a firebox having a plurality of upright side walls connected to each other at adjacent corners and disposed at angles to each other to form a firebox space, having a bottom, and at least two substantially similarly spaced fire limiters arranged on the bottom of the firebox, each comprising two connected oblong wall elements with parallel longitudinal edges, said oblong elements being connected together to form an angle of from 90°

to 120°

with each other, said oblong walls being inclined outwardly in relation to the vertical by an angle of from 20°

to 30°

, said fire limiters being arranged so that one oblong wall element of each fire limiter faces each other with the oblong walls inclined away from each other in the vertical direction for confining charcoal therebetween on the firebox bottom, each of said fire limiters having depending spaced apart bases extending downwardly from a lower one of said parallel longitudinal edges of said wall elements and supporting said limiter wall elements above said firebox spaced bottom, so as to define a combustion air passage adjacent said firebox bottom.
