Abstract
Abstract A portable electric grill appliance comprising a lower and an upper grill chassis each of which has a bottom wall, side walls about the bottom wall and a grill plate of heat conductive material defining an upper wall. A resistive heating element is secured in contact with the grill plate of each chassis. The lower and upper chassis are interconnected by hinge means along one of their side walls to permit the upper chassis to be displaced through a 180* arc from a position where both grill plates lie side-by-side in a common horizontal plane to a further position where both grill plates face each other in substantial juxtaposition. Support means are also provided to support each of the chassis bottom walls above the common horizontal plane.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
298 words
A portable electric grill appliance comprising a lower and upper grill chassis, each said grill chassis having a bottom wall, side walls about said bottom wall and a grill plate of heat conductive material defining an upper wall; a resistive heating element secured within a channel provided on the underface of said grill plate of each said chassis whereby a substantial portion of said heating element will be encased in said grill plate to minimize heat radiation in the area between said chassis bottom wall and said grill plate, a hinge connecting said lower and upper chassis along one of their side walls to permit said upper chassis to be displaced through an arc from a position where both said grill plates lie side-by-side in a common horizontal plane to a further position where both said grill plates face each other in substantial juxtaposItion to a further position where at least the lower grill plate is accessible, said hinge having a channel member secured to each end walls of said bottom chassis adjacent the end edge of a side wall and extending above said lower chassis grill plate, an elongated connector member secured to a side wall of said upper chassis near each end edge thereof and extending above said upper chassis grill plate to define a connecting end, said channel members and said connector members extending above said lower and upper chassis bottom wall to constitute support legs, a further leg secured to each said lower and upper chassis and located centrally of the side wall remote from the hinge, said support legs and further leg supporting the bottom wall of each said chassis above a common horizontal plane, and support means for supporting each saId chassis bottom wall above said common horizontal plane when resting thereon.

Dependent Claim
298 words
A portable electric grill appliance comprising a lower and upper grill chassis, each said grill chassis having a bottom wall, side walls about said bottom wall and a grill plate of heat conductive material defining an upper wall; a resistive heating element secured within a channel provided on the underface of said grill plate of each said chassis whereby a substantial portion of said heating element will be encased in said grill plate to minimize heat radiation in the area between said chassis bottom wall and said grill plate, a hinge connecting said lower and upper chassis along one of their side walls to permit said upper chassis to be displaced through an arc from a position where both said grill plates lie side-by-side in a common horizontal plane to a further position where both said grill plates face each other in substantial juxtaposItion to a further position where at least the lower grill plate is accessible, said hinge having a channel member secured to each end walls of said bottom chassis adjacent the end edge of a side wall and extending above said lower chassis grill plate, an elongated connector member secured to a side wall of said upper chassis near each end edge thereof and extending above said upper chassis grill plate to define a connecting end, said channel members and said connector members extending above said lower and upper chassis bottom wall to constitute support legs, a further leg secured to each said lower and upper chassis and located centrally of the side wall remote from the hinge, said support legs and further leg supporting the bottom wall of each said chassis above a common horizontal plane, and support means for supporting each saId chassis bottom wall above said common horizontal plane when resting thereon.
Claim 3
Dependent Claim
29 words
An electric appliance as claimed in claim 1, wherein said channel is formed by a metallic channel cover which is detachably secured to said underface of said grill plate.
Claim 4
Dependent Claim
52 words
An electric appliance as claimed in claim 1, wherein said channel is integrally formed in said grill underface to receive said heating element, said channel having spaced apart flanges extending outwardly of said underface to accommodate said heating element therebetween and a heat conducting cover positioned and retained over said heating element.
Claim 5
Dependent Claim
33 words
An electric appliance as claimed in claim 3, wherein said flanges are crimped at their upper end over said heat conducting cover to retain said cover in facial contact with said heating element.
Claim 6
Dependent Claim
125 words
An electric appliance as claimed in claim 1, wherein each said grill chassis are of substantially rectangular shape and define two elongated side walls and two end walls, an elongated slot in said channel member extending vertically to the surface of said lower chassis grill plate, and a pin of circular transverse cross-section in said connecting end of said connector member having an enlarged disc-shaped end and extending outwardly towards a respective end wall of said upper chassis, each said connecting end being received and retained within a respective one of said slots to thereby interconnect said upper chassis to said lower chassis and permitting said upper chassis displacement and said upper chassis to be spaced a predetermined distance above said bottom chassis when juxtaposed.
Claim 7
Dependent Claim
43 words
An electric appliance as claimed in claim 5, wherein said slot has a bottom opening to permit passage of said connecting end and an elongated throat opening extending from above said bottom opening along said slot to accommodate movement of said pin therealong.
Claim 8
Dependent Claim
34 words
An electric appliance as claimed in claim 6, wherein said pin has a circular cross-section and said slot has arcuate ends to permit rotatable support of said pin in either one of said ends.
Claim 9
Dependent Claim
113 words
An electric appliance as claimed in claim 1, wherein said heating element in said upper chassis is connected to electrical terminals in said lower chassis by means of electrical wires passing through a respective side wall of both said chassis, said electrical wires passing through a longitudinal hollow member secured adjacent one of its ends in a hole in one of said respective side walls between said further wall means and bottom wall and extending through an adjacent hole in the other respective side wall whereby a portion only of said hollow member will move in and out of said other side wall as said upper chassis is displaced through said 180* arc.
Claim 10
Dependent Claim
43 words
An electric appliance as claimed in claim 1, wherein a sheet of heat reflecting material is secured in a substantially horizontal plane and elevated from said bottom wall whereby heat radiated by said grill plate will be reflected back on said grill plate.
Claim 11
Dependent Claim
36 words
An electric applicance as claimed in claim 9, wherein at least one of said side walls of each said lower and upper chassis is perforated to provide ventilation between said grill plate and said bottom wall.
