A solid disk surface unit mounted in a glass or ceramic support surface, comprising a plate member of cast material with one or more resistive heating elements mounted to the underside thereof and a thermally conductive cover member enclosing the underside of the plate member with its peripheral edge in close thermal contact with the plate member near its periphery, is provided with a thermally responsive switching device thermally coupled to the cover member and adapted to respond to the surface temperature of the cover member at a point relatively remote from its peripheral edge. The switching device is operative to remove power from the resistive heating elements of the surface unit when the sensed cover member temperature exceeds a predetermined threshold temperature, thereby protecting the glass support surface from damage due to thermal stresses resulting from hot spots occurring near the periphery of the surface of the plate member.

A hinge structure is formed by at least two ears projecting from one side edge of a panel with each of the ears being provided with a lobe extending in the same direction from its respective ear and spaced from the edge of the panel to provide an undercut. The ears are adapted to be projected through cooperating slots in a second panel to which the first panel is to be hinged and slid laterally in the slots to position each ear on the opposite side of the second panel and out of alignment with its slot so that a portion of the second panel is received in the undercut or space between the adjacent lobe and the edge of the first panel. A tab moveable from an open position permitting insertion of the ear into one of the slots to a locked position to engage each ear in that one slot and prevent reverse movement of the first panel to move the lobes from behind the second panel is provided to lock the hinge parts together.

A glass top countertop range is mounted on a structure formed by a first box structure that fits through a hole in the countertop and is supported by a peripheral flange and a second, but inverted, box structure significantly smaller than the first box structure and telescopingly received in the first box structure to provide an air space between the two box structures. The top of the second box structure lies in face to face relationship with a glass top of the range and the glass top is secured to the and supported by the second box structure which in turn is supported in the first box structure.
