tions 22 of the casings 2| are compressed by the
edges of the holes 16 in passing therethrough
during insertion, and the casings are forced into
a position in which the edges of the holes l6
lie in the grooves 24. The casings 2| may be po
sitioned on the ends of the bars l8 and 19 before
the shelf is positioned in the cabinet and the
casings forced into their proper positions in the
holes I 6 by the ends of the bars.
10
In removing the shelves II from the cabinet,
the shelf is ?rst moved laterally and the pro
jecting ends of the transverse bars l8 and I9
force the extensible body portion 22 of the cas
ings 2| outwardly. The casings 2| thus allow a
15 sufllcient lateral displacement of the shelves to
free or disengage the end of the transverse bars
II and I! at one end of the shelf, from their sup
porting casings. The shelf may then be tilted,
as shown in Fig. 2, upwardly a su?icient amount
that the opposite ends of the transverse bars I 8
and I 9 can then be freed or disengaged from their
supporting casings.
Similarly, in placing‘ one
of the removable shelves II in position within the
cooling compartment H, the ends of the trans
verse bars l8 and I! at one end of the shelf are
inserted or engaged in their supporting casings 2|
and the casings are then stretched a suilicient
amount to allow the ends of the transverse bars
at the opposite end of the shelf to be brought
30 into engaging position in their respective sup
porting casings.
'
It will thus be seen that the cup-shaped sup
porting casings 2| form a tight seal about?the
edges of the holes it formed in the inner liner l2
and prevent the leakage of air from the interior
of the compartment ll into the insulation l3.
Also, since the outer ends of the casings 2| are
closed air cannot enter the insulation 13 through
the holes It even when the shelves ll are removed
40 from the cabinet.
While I have shown a particular embodiment
of my invention in connection with a cabinet for
a household type refrigerator, I do not desire
my invention to be limited to the particular con
45 struction shown and described and I intend, in
the appended claims, to cover all modi?cations
‘within the spirit and scope of my invention.
What I claim as new and desire to secure by
