SHELF STRUCTURE
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.

Description
BACKGROUND OF THE INVENTION
This invention relates to shelf structure, and more particularly
cantilevered sliding shelf structure. While of broader
applicability, the invention has particular utility in the field of
household refrigerators.
Adjustable cantilevered shelves have met with considerable success
in refrigerators, and it is an objective of this invention to
provide novel and improved structure for adapting conventional,
adjustably mounted cantilever support brackets of the type used for
such shelves, to the support of both shelves and food storage pans,
or the like.
SUMMARY OF THE INVENTION
In achievement of the foregoing and other objectives, the invention
provides, in cabinet structure, a pair of laterally spaced,
parallely extending cantilevered shelf brackets, a slidable shelf
runner on each said bracket, a shelf spanning the space between
said brackets and supported by said runners, means defining a
longitudinal groove on each said runner, and food storage pan means
disposed below said shelf and slidably supported in said grooves,
Selectively releasable detent means affords either sliding
withdrawal of the storage pan means relative to the shelf, or
slidable withdrawal of the shelf and pan means as a unit.
The manner in which the foregoing as well as other objectives and
advantages of the invention may best be achieved will be more fully
understood from the following description, taken in light of the
accompanying drawing.

including, in the lower portion of its food compartment, sliding
food storage pan and shelf support means embodying the
invention;
FIG. 2 is a sectional showing, looking generally in the direction
indicated by the line 2--2 applied to the support means illustrated
in FIG. 1, but with the storage pan removed;
FIG. 3 is a sectional showing of the storage pan and shelf support
means as seen looking generally in the direction of arrows 3--3
applied to the illustration thereof in FIG. 2;
FIG. 4 is a perspective showing of the storage pan and shelf
support means illustrated in the preceding figures, but on a
slightly larger scale and with parts broken away;
FIG. 5 is a sectional view taken generally along the line indicated
by arrows 5--5 applied to FIG. 4, and illustrating details of latch
means for releasably interlocking elements of the support means;
and
FIG. 6 is a sectional showing of the support means as seen looking
generally in the direction of arrows 6--6 applied to the
illustration thereof in FIG. 5.
DESCRIPTION OF THE PREFERRED EMBODIMENT
With more detailed reference to the drawing, and first to FIGS. 1
and 4, there is illustrated a refrigerator 10 which in this case is
of the so-called side-by-side type and comprises a left-hand
freezing compartment, over which door 11 is closed, and a
right-hand above-freezing food storage compartment 12 provided with
a door 13. The latter door is disposed in open position for the
sake of convenience of illustration. Compartment 12 is cooled by
forced flow therethrough of relatively cold air from the freezing
compartment, in accordance with conventional practice. Storage of
foods in compartment 12 is accommodated by shelves designated
generally by the reference numeral 14, and including cantilevered
support brackets of the type seen at 15, and suspended from
vertically extending, apertured support bars 16 on the rear wall of
the compartment.
The invention is embodied in a combination slidable food storage
pan and shelf assembly 17 disposed in the lower region of
compartment 12. With reference also to FIGS. 2 and 3, the lower
pair of spaced brackets 15 is supported, in cantilever fashion, by
hooks 18 thereon extending into and engaging edges of apertures 19
in bars 16. Each of brackets 15 includes an inwardly turned
horizontally extending flange 20 and a vertically extending,
longitudinally tapered main portion 21. A tie rod 26 is affixed at
each end to a corresponding portion 21 of a bracket 15, whereby the
brackets and rod are handleable as a unit.
A slide member 22 frames a glass shelf 23, and includes spaced
parallel sides or runners 24 and an interconnecting rear side 25,
each of identically extruded material, such as metal or plastic.
The several sides conveniently can be formed of one extrusion bent
to generally U-shape by known techniques, or it may be made up of
separate, suitably joined lengths of extruded stock. Each side
runner 24 includes a glass receiving groove 32, and an inverted
L-shaped groove 27 that mates with portions 20 and 21 of the
bracket 15 to provide for sliding support of the frame 22 and shelf
23 thereon. Each side runner 24 further includes an inwardly facing
horizontally extending groove 28 that slidably receives a flanged
upper edge 30 of a storage pan 29. Framing of glass shelf 23 is
completed by a front, transversely extending member 31 provided
with a groove 33 (FIG. 3) receiving the shelf, and which member 31
blends with and is fastened to, as by cementing, the forward ends
of side runners 24.
As is best seen in FIG. 5, the member 22, the glass shelf 23, and
the food storage pan 29, which in the preferred embodiment is a
crisper pan, are slidable as a unit on rails or brackets 15.
Further, crisper pan 29 is slidable on member 22, and, as is seen
also in FIG. 6, selectivity of sliding is accommodated by a detent,
such as projection 34, on frame member 31 releasably retained in a
recess, such as slot 35, formed in each of brackets 15. Although
projection 34 is conveniently illustrated as being formed on front
frame member 31, it will be understood that the invention
contemplates that said projection may be provided instead on a
corresponding runner 24.
In operation, and assuming the detent is positioned as shown in
FIGS. 5 and 6, an upward and forward pull on member 31 will
disengage the above described detent, and will slide the member 22,
shelf 23, and crisper pan 29, as a unit, forwardly on brackets 15.
As is best seen in FIG. 5, the vertical extent of groove 27
accommodates upward, pivotal movement of member 22 sufficient to
move projection 34 out of slot 35. Alternatively, a forward pull on
the downturned handle portion 37 of crisper pan 29 (FIG. 6) results
in forward sliding movement of the pan with respect to the member
22, as is provided for by sliding engagement of pan flange 30 in
groove 28.
It will be appreciated that the novel combination of this invention
may be utilized at other convenient locations within the cabinet.
For example it may be embodied in the shelf and bracket structure
14, 15 associated with a meat storage pan 36 located in the upper
region of food compartment 12. Also, the assembly 17 may be moved
to such other locations in the cabinet as may be provided for by
the adjustability of the shelf brackets.
Summarizing, the invention herein disclosed provides improved
structure for adapting conventional, adjustably mounted cantilever
support brackets to the adjustable support of both shelves and
pans.
