Abstract
A telescoping rack assembly for an oven cavity includes a rack extendable upon a primary rack frame which, in turn, is mounted for sliding movement relative to the oven cavity. Therefore, with this arrangement, multiple extensions for the rack is available. The rack is preferably supported upon guides carried by the rack frame, along with multiple sets of rollers. A secondary rack frame can be provided to slidably support the primary rack frame such that a further extension is available.
Claims20
A cooking appliance comprising:
- an oven cavity having top, bottom, rear and side wall portions and an open frontal portion enabling access to within the oven cavity;
- and
- a telescoping rack assembly supported in the oven cavity, said rack assembly including:
- a) a rack frame supported by the oven cavity for sliding movement into and at least partially out of the oven cavity;
- b) a rack supported by the rack frame for sliding movement relative to both the oven cavity and the rack frame, said rack being extendable from a retracted position wholly within the oven cavity to an extended position outside the oven cavity;
- and
- c) a pair of laterally spaced guides on the rack frame, said rack being slidably supported through the guides relative to the rack frame, wherein the guides include lower front end portions which are ramped upwardly to aid in preventing the rack from inadvertently sliding out of the retracted position.
A cooking appliance comprising:
- an oven cavity having top, bottom, rear and side wall portions and an open frontal portion enabling access to within the oven cavity;
- and
- a telescoping rack assembly supported in the oven cavity, said rack assembly including:
- a) a rack frame supported by the oven cavity for sliding movement into and at least partially out of the oven cavity;
- b) a rack supported by the rack frame for sliding movement relative to both the oven cavity and the rack frame, said rack being extendable from a retracted position wholly within the oven cavity to an extended position outside the oven cavity;
- and
- c) at least one stop abstinent acting between the rack and the rack frame to limit the extension of the rack relative to the rack frame, wherein the rack includes a support rod, said support rod including a transversely, substantially horizontally extending portion adapted to engage the at least one stop abutment to limit the extension of the rack.
A cooking appliance comprising:
- an oven cavity having top, bottom, rear and side wall portions and an open frontal portion enabling access to within the oven cavity;
- and
- a telescoping rack assembly supported in the oven cavity, said rack assembly including:
- a) a rack frame supported by the oven cavity for sliding movement into and at least partially out of the oven cavity;
- b) a rack supported by the rack frame for sliding movement relative to both the oven cavity and the rack frame from a retracted position wholly within the oven cavity to an extended position outside the oven cavity, even with the rack frame being entirely within the oven cavity;
- and
- c) a secondary rack frame interposed between the rack frame and the oven cavity such that the rack frame is indirectly supported by the oven cavity and the secondary rack frame is directly, slidably supported by the oven cavity thereby enabling even further extension of the rack outside the oven cavity.
In a cooking appliance including an oven cavity having top, bottom, rear and side wall portions and an open frontal portion enabling access to within the oven cavity, a telescoping rack assembly supported in the oven cavity comprising:
- a rack frame supported by the oven cavity for sliding movement into and at least partially out of the oven cavity for a first distance;
- a rack supported by the rack frame for sliding movement relative to the rack frame for a second distance, wherein the rack is extendable from a retracted position within the oven cavity to an extended position which is spaced from the retracted position by the first and second distances;
- and
- detent means for seating the rack relative to the rack frame in the retracted position.
