Abstract

ABSTRACT OF THE DISCLOSURE:
The invention relates to a portable grill for firing with preferably solid fuel, e.g. charcoal or the like. The grill comprises a furnace, defined by a rectangular bottom wall, two end walls and two side walls, and a support for a grill grating or the like are arranged above the furnace. The object of the invention is to provide a grill requiring very small storage space and being simple to get ready for use. This is achieved in that the bottom wall of the furnace is pivotally connected to each end wall by at least two pivots for pivotal movement around a line that is parallel to and situated adjacent the edge of the bottom wall facing the end wall, and in that each side wall is pivotally connected to each end wall by a pivot which permits turning movement both around a line con-necting the pivots at both ends of the side wall and around a line that is parallel to and situated adjacent the edge of the side wall facing the end wall, so that the grill, after turning of the side walls to positions where they are parallel to the bottom wall, is collapsible to a substantially flat condition.

Description

351~

The present invention relates to a portable grill for firing with preferably solid fuel! said grill comprising a furnace and support means for a grill grating or the like arranged above the furnace, said furnace being de~ined by a substantially flat, rectangular bottom wall, two end walls and two sicle walls.
Previously known grills of this kind comprise in general a box that usually is provided with a number of legs, which in many cases are removable in order to facilitate trans- -port and storage o~ the grill. These grills have the dis-advantage that they require relatively large storage space when not in use, and grills having removable legs or the like further require some assembly work before use and some dis-mantling after use.
The object of the present invention is to provide a portable grill of the above-mentioned kind, which requires very small storage space and which in a very simple way can be made ready for use and after use be prepared for storageO
Accordingly, the invention as herein broadly claimed is a portable grill for firing with preferably solid fuel which comprises a furnace and a support for a grill grating or the like arranged above the furnace. The latter is defined by a substantially flat, rectangular bottom wall, two end walls and two side walls. The bottom wall is pivotally connected to each end wall by at least two pivot means for pivotal monement around a line that is parallel to and situated adjacent the edge of the bottom wall facing the end wall. Each side wall is pivotally connected to each end wall by a pivot means, which permits turning movement both around a line connecting the pi-vot means at both ends of the side walls and, with both sidewalls turned parallel to the bottom wall~ around a line that is parallel to and situated adjacent the edge of the side wall S~4 facing the encl wall. Each pivot means comprises an eye that is passed through an opening near the edge of the side wall or the bottom wall and a pin or the like which is fixed to the eye and is rota-tably but axi.ally non-~lidably arranged in an opening in the end wall. The side walls are of different heiyht, so that the yrill, a~ter turn.iny o:E the side wall to positions where -they are parallel to the bottom wall, is collapsible to a substan-tially flat condition.
An embodiment of the invention is described in detail below with reference to the accompanying drawings, on which Fig. 1 is a _ _ /

perst~ectivc vlew of a grill accord.ing -to one embodiment o~ the invcn-tion, said gri.Ll belng rcady for use, ~ig. 2 shows the gri]l accortling to Fig. 1 par-tially colla.psed, and ]?lg. 3 shows tht?

Thc drawings show a gril]. accordin~r to the invc?rl-t:ion, S~l..i.(l gr~.i.l1. incl.udinfr a rurnace t;hat is dc:Ei.ned by a :~lat, xcc-t~u1glllar.~ boti;oln~lal~ l., -two erld wal:l.s 2 arld 3 ~nd two side w,aJls and 5. Tht? Curnace ha~ the sha~e of a bo~ hav.ing ~ubs-tan-ti~ally rectangul.1r cross sectlon, and ~lhen the grill is used :fuel, e.g. charcoal or -the like, is placed in -the :furnace, and -to avoid di-rty.in~ the fuel may be placed on a removable metal foi.l or the llke. The end walls 2 ~nd 3 are provided with slo-ts 6 in their edges ad jacen-t -the si.de~ wall 5, and the side wall ~l is provided with holes 7 in .its cen-tre porti.on, sald holes being provided c~-t; tlle s~me height as -the slots 6. A gril].
grating 8 is provided with projecting pins that are arranged to be received in the slots 6 and one of the holes 7, respec--tively, and by placing the plns ;n diffcrent slots and hole -the grill grating 8 may be placed at the required dis-tance above the bottom ~all l of the ~urnace. In order to facili--tate the handlirlg of the grill grating it is provided wi-th a :foldable handle 9. The end walls 2 and 3 are fllrther provided with openings lO at -thcir lower portions.
The bot-tom wall l and the side walls 4 and 5 are pivotally connected to the end walls 2 and 3 by means of a number of pi~ro-t means ll. The~ bottom l is connected to each side wall 2 and 3 b~ means of two pivot means ll, while each of the slde wa~ and 5 is connectetl i;o ca.ch end wal] by mcans o:f a single pivo-t means ll which is arranged adjacen-t to the -~0 ~l~per e~dgt? of 1;he resp~ct;ve side wall. Each of the pivo-t means ll i.ncllldes an eye -tha-t is passed -through an openlng near -that edge of the si(lr?~:/all or l;he bottom wal1 that is facing the respectlve elld wa.:ll., and cl pin or the l.ike which is con-nected to the ey~? and is rotatably but axially non-slidably ar-rarlged in an open.i.ng in the end wall 2 or 3. In -the embodimen-t sho~ in the d~a~li.np;s each pivot mrv~ans 1~ cnnsists o:f a spllt p.i,n, the leg~v oL`~lh:ich are pa,scled through the openi.ng .in the end ~a:l.l 2 or 3 ~lnd are spread a part on the outs.ide o~ said end t'/all . In th:i.s manner a pivotable connection is obtained, ~hi.ch pcrmits movement be-twecn the two connected details in d.i.:E`:rerent dlrections. As an ex~nple each of -the sidc walls ~ and 5 may bc turned around a l.ine connec-t:ing the two pivot mec~ns 11 of the side wall and may be turned around lines which a.re pa.rallel to and situated adjacent the edge of -the side wall facing the end wall. Due to -the fact that thc bottom wall 1 is connected to each end wall 2 and 3 by means of two p.ivot means 11 the bottom wall 1 is turna.ble in rela-tion to each end wall only along a li.ne which is parallel to and sl-tu~ted ad-jacen-t -the edge of the bottom walI ~acing the respective end wall.
When the grill according to the invention is rea.dy for use the different details are positioned as shown in Fig~
1. '~hereby the side walls 4 an,d 5 will contact the bottom wall 1 ~Ji-th their lower edges, while the short edges of the side walls are in contact with the end walls 2 ~ld 3. '~hus, relative swinging movement between the bottom wall 1 and the end walls 2 and 3 is prohibitcd. ~fter use the grill may be folded by turning -the side walls 4 and 5 around their pivot ... .. ..
means 11 to the positions shown in Fig. 2, where the side walls 4 and 5 are subs-tantially horizon-tal and parallel to the bo-t-tom wall 1. trhereafter the grill may be collapsed to -the con-dition shown ln Fig. 3 by -turning the bottom wall 1 and the side walls ~ and 5 relat.ive to the end walls 2 a,nd 3, which is made possiblc by ~ o:f t;he pivot means 11. In collapsed _~~

c~nclltlon the op~?ning 10 may, as sho~M i,n F.ig. 3, be used for carrying I;he ~.~i],l, which due -to its fla-t form i.n collapsed con-dit;on ls very f~9y to store.
';Jherl the gri.l] is -to be c.rected -the end wa.lls 2 and 3 a.re turncd in re].atlon -to -I;he bo-t;-tom ~a,l:l. 1. and the side ~a:l..'l.s ~ ~md 'j to the posit;:ion shown by dash and dot li.nes in L~'.i.g. 2. ~]l.h.i.9 may be per~ormed simply by lifting the left haMd e(lge of thc cntl ~all 2, as ~ccn in Fi.g. ~, and when thc end wal],s 2 and 3 are substan-t;.ally pcrpendlcll].ar to the bottom 6hlC~;

The ercction of the grill is thercfore very simple, and further -the siae wa.lls ~ and 5, in turned do~in posi-tion~ will lock the whole gr.ill, 9() that no separate locking means are requi- ' red to lock the~ grill in erccted position.
