Abstract: A vent system for a cooking appliance is disclosed. The appliance has a cooktop surface supporting a plurality of surface heating units. The vent system includes a vent box mounted beneath the cooktop surface; a telescopic vent assembly telescopically mounted relative to the vent box, the telescopic vent assembly being movable between a retracted position proximate the cooktop surface and an extended position above the cooktop surface; a retention unit configured to releasably hold the telescopic vent assembly in the retracted position; and a stored energy mechanical drive unit configured to move the telescopic vent assembly in a first direction to the extended position upon release of the retention unit.

Abstract: An adjustable support assembly particularly for use in supporting the bottom shelf in a household refrigerator including a support bracket having a hollow cylindrical sleeve with an interior circumferential surface having a first longitudinal portion with an array of inwardly directed elongated tooth projections along and substantially perpendicular to the longitudinal axis of the sleeve and a second longitudinal smooth portion adjacent the first portion. There is a brace having an outside diameter slightly smaller than the inside diameter of the sleeve and has a circumferential outer surface with a first longitudinal portion with an array of outwardly directed elongated tooth projections along and substantially perpendicular to the longitudinal axis of the brace and a second longitudinal smooth portion adjacent the first portion, said projections on the first portion being complementary to the tooth projections on the first portion of the interior surface of the sleeve.
