Abstract
Abstract A unitary shelf and food storage pan support structure for cabinets. An extruded member supported on cantilevered shelf brackets includes a pair of opposed runners which frame an imperforate shelf and are provided with a set of grooves that slidably support a food storage pan. The runners include another set of grooves that slidably engage the shelf brackets. The arrangement, in combination with selectively releasable detent means, affords either sliding withdrawal of the storage pan relative to the imperforate shelf, or sliding withdrawal of the pan and shelf as a unit.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
188 words
In cabinet structure: a pair of elongate, laterally spaced, parallelly extending spaced rail members having spaced supporting means therefore; means defining a pair of parallelly extending shelf support runners mounted for slidable movements on said rail members, and each having a groove formed therein interengageable with said rail members in provision of the recited slidable movements; a transversely extending member positioned to interconnect end portions of said support runners; said shelf support runners having confronting first grooves and said transversely extending member having a first groove aligned with said confronting first grooves, said confronting and aligned first grooves forming first groove means adapted to support at least three sides of a shelf; means defining a shelf spanning the region between said shelf support runners and received within said first groove means, in provision of the recited support of said shelf; and each said shelf support runner having confronting second grooves and said transversely extending member having a second groove aligned with said last recited confronting second grooves and forming therewith second groove means positioned to receive and support at least three sides of drawer means beneath said shelf.
Claim 2
Dependent Claim
188 words
In cabinet structure: a pair of elongate, laterally spaced, parallelly extending spaced rail members having spaced supporting means therefore; means defining a pair of parallelly extending shelf support runners mounted for slidable movements on said rail members, and each having a groove formed therein interengageable with said rail members in provision of the recited slidable movements; a transversely extending member positioned to interconnect end portions of said support runners; said shelf support runners having confronting first grooves and said transversely extending member having a first groove aligned with said confronting first grooves, said confronting and aligned first grooves forming first groove means adapted to support at least three sides of a shelf; means defining a shelf spanning the region between said shelf support runners and received within said first groove means, in provision of the recited support of said shelf; and each said shelf support runner having confronting second grooves and said transversely extending member having a second groove aligned with said last recited confronting second grooves and forming therewith second groove means positioned to receive and support at least three sides of drawer means beneath said shelf.
Claim 3
Dependent Claim
70 words
Cabinet structure according to claim 1, and further including detent means comprising cooperable, releasably engageable elements on at least one of said shelf runners and on a corresponding one of said rail members, and operable to engage and thereby provide for sliding withdrawal of such drawer means relative to said shelf, or to disengage and thereby provide for sliding withdrawal of said shelf and such drawer means as a unit.
Claim 4
Dependent Claim
47 words
Cabinet structure according to claim 1 and further characterized in that each of said rail members includes a vertically extending portion and a horizontally extending flange portion, and further in that each of said grooves is generally L-shaped and is slidably engageable with said last recited portions.
Claim 5
Dependent Claim
23 words
Cabinet structure according to claim 3 and further characterized in that said rail members are cantilevered supported and rigidly interconnected to one another.
Claim 6
Dependent Claim
42 words
Cabinet structure according to claim 1, and further characterized by the inclusion of a front, transversely extending member having a longitudinally extending groove receiving a forwardly presented edge portion of said shelf, and extending across end regions of said shelf support runners.
Claim 7
Dependent Claim
43 words
Cabinet structure according to claim 2, and further characterized in that said detent means comprises means defining a recess in at least one of said rail members, and means defining a projection on a corresponding shelf support runner releasably retained in said recess.
