This invention relates to shelf structures and in par
ticular to shelf supports.
In cabinets such as refrigerator cabinets, it is desirable
to provide facilitated accessibility to the interior thereof
by means of shelf stnuctures which are arranged to be
moved outwardly relative to the cabinet when desired.
Conventionally, such shelf structures are arranged to swing
between extreme positions within the cabinet and out
wardly thereof. The present invention is concerned with
a new and improved swing-out shelf support structure.
A principal feature of the present invention is, there
fore, the provision of a new and improved shelf support
structure.
Another lfeature of the invention is the provision of
such a shelf support structure including new and improved
means providing vertical adjustability of the shelf while
assuring optimum swinging movement as desired.
A further feature of the invention is the provision
of such a shelf support structure including new and im
proved pivot means for swinging the shelf about an ac
curately maintained vertical axis.
Still another feature of the invention is the provision
of such a shelf support structure including new and im
proved means Ifor connecting the shelf support to the pivot
member.
Other features and advantages of the invention will
be apparent from the following description taken in con
nection `with the accompanying drawings wherein:
FIG. 1 is an elevation of a swing-out shelf device includ
with a suitable door 20 for selectively closing the front
opening of chamber 16.
Shelf support structure 13 provides an improved facili
tated swinging of the shelves 11 and .12 about the vertical
axis of the elongate upright post member `21 secured to
the liner y17 by means of a pair of brackets 22 and 23.
The upper bracket 22 includes an upper turned flange 24
and a lower turned flange `25 and the lower bracket 23
includes a lower turned ñange 27, through each of which
flanges the post 21 extends. Each bracket includes a base
portion 28 facially juxtaposed to the liner 1'7 and through
which suitable screws 29 extend for threaded engagement
with a channel 3i) disposed on the opposite side of the
liner 17 within the body of insulation 18. As best seen in
FIG. 6, the post 21 is provided subjacent head 311 with a
cylindrical portion 32 including a radial enlargement 33
keyed to a corresponding opening 34 in the uppermost
bracket 24 thereby locking the post against rotation. A
nut 85 is threaded on the post below ñange 27 to co
20 operate with head 31 in retaining the post 21 against axial
movement in the brackets 22 and 23.
The shelf support structure 13 further includes an upper
pivot member 35 and a lower pivot member 36 pivotally
mounted on post 21 for swinging movement about the
axis of the post. A connecting member .37 is carried by
pivot member 35 and a similar connecting member 38
is carried by the pivot member 36 for movement with
the pivot members about the axis of post 21. Connect
ing members 37 and 38 are vertically yadjustably posi
30 tioned on the pivot members by means of co-operating
teeth 39 on the pivot members and a catch 40 carried by
the connecting member.
Secured to each connecting
member is a tubular support 41 which co-operates with a
frame 42 to support a shelf frame assembly 43 and define
a peripheral upstanding wall about the shelf frame as
sembly.

In the exemplary embodiment of the invention as dis
closed in the drawings, a swing-out shelf structure gen
erally designated 141 is shown to comprise a pair of shelves
1_1 and 12 swingably carried by a support structure gen
erally designated 13 secured to a wall portion 14 of a con
47 and the upper portion 49 of the arm end 47 is un
toothed.
rThe connecting member 37 comprises a vertically elon
gate, generally J-sectioned member having a long arm
56, a turned end 51 and a shont «arm 52 terminating in an
inturned end 53. Thus, as best seen in FIG. 3, the con
necting member generally embraces the pivot member for
pivotal movement therewith. The turned end 53 outward
ly rdefines a sliding surface 54 slidably engaging the slid
ing ysurface 48 of «the pivot member end 47. A set screw
55 `extends through the short arm 52 to project inwardly
'from a flat inner surface 56 of the short arm confronting
