This invention relates to demountable display
on the leg, the rivet head l8 will engage the
racks or the like, more particularly for use in
marginsbi the slot it, the reduced portion 20
retail stores for displaying bakery goods.
Among other objects the invention aims to pro
vide an improved rack of this type which can
be shipped in knock~down form and which can
be readily assembled and which at the same time
is sturdy and secure.
Other objects and advantages will be appar
‘ ent from the following description taken together
with the accompanying drawings in which
Figure 1 is an assembled view, one leg being
broken away for clearness of description.
Figure 2 is a partial enlarged section taken on
the line 2—2 of Figure 1.
Figure 3 is a similar View taken on the line
3——3v of Figure 2.
Figure 4 is a partial cross section taken on the
line 4-—@ of Figure 1.
Figure 5 is a fragmentary perspective view of
one upper front corner of the rack in disassem
bled relation.
Figure 6 is a partial vertical section taken on
the lines 6'—& of Figure 1 and Figure 7.
Figure 7 is a partial part top plan view of the
structure of Figure 6.
In theillustrative construction there is shown
in general four metal legs, a rear pair being num
bered l0 and M respectively and a front pair I2
and 13 respectively. These legs are desirably of
angular cross section and as here shown-of gen
erally L-shape in such cross section.
Arranged to be interengaged with the legs are
upper and lower trays I4 and 15 respectively, the
interengagement of these trays with the legs
serving also to maintain the parts in rack-like
assembly. Since loose bolts, nuts or screws are
apt to become lost and are diliicult to maintain
in tight position, the invention desirably includes
40 slip engagement means in the nature of tongue
and groove connections.
For the bottom tray !5, for example, slots iii
are provided in the vertical walls of the tray and
at the corners thereof. These slots I6 are con
' tinued slightly into the bottom 57 of the tray as
at 16a; where the slot is somewhat enlarged so
that the head l8 of a rivet 19 may be received
in the enlargement 96a of the slot it. There
may be one such rivet carried by each of the
legs W, H, l2’ and £3 with the head !8 facing in
wardly when the legs are arranged with their
L-shaped faces toward each other. Thus when
the tray is abutted against the leg with the head
I8 of the rivet is received in the slot enlarge
55 ment Ilia and the tray then pushed downwardly
of the rivet slidirg in the slot until it comes
to rest in the upper end l6b thereof.
When each of the legs is thus engaged with 5
a corner of the lower tray !5, the tray will then
be supported on the legs as well as at the same
time maintaining the legs in upright position.
‘This assembly is further secured by interengage
ment of the upper tray M with the legs. As here 10
shown, the upper tray hi and the rear legs in and
H may be secured together by a slot-and-rivet
arrangement similar to that just described for
the lower tray.
In order to provide an improved rigidity for 15
the assembled structure, which so frequently de
mountable structures lack, the present invention
contemplates an enhanced tongue-and-groove
connection for at least two of the legs and at
least one of the trays, such enhanced connection 20
being desirably in the form of a telescoping ar
rangement of one or more, in this instance the
two front legs 12 and i3, and the upper tray 14.
As best shown in Figs. 4 and 5, the upper tray
at its front corners respectively is provided with
an upright angle member 21 the side margins of 25
which are folded over upon itself as at 22, 23
forming ?anges in spaced relation with the angle
member to provide a vertically extended angular
somewhat L-shaped socket into which the L
shaped leg l2 may be telescoped, as the male 30
angular member of the connection. The margins
22, 23 are folded over outwardly of the angle of
the socket and are spaced from the main member
2| just sufficient to permit the margins of the
leg E2 to slide therebetween by a vertical recip
rocating motion. In order to facilitate entry of
the leg into the socket thus provided the folded
over margin ?ange 22 as here shown at one side
of the member 2!, is discontinued, as at 24, short
of the other side 23, so that the leg need be en
gaged with only one ?ange at a time, that is
?rst the ?ange 23, which then serves to guide the
leg into the ?ange 22. Advantageously Where the
?ange 22 is discontinued as at 24 and also where
the ?ange 23 is discontinued ,as at 25, a rounded
contour is provided to avoid sharp corners and
also to assist in the interengagement of the parts.
Desirably also abutment means are provided
for limiting the telescoping engagement of the 50
leg l2 and the socket thus provided. As here
shown, such abutment means are provided by
folding over the upper end margin of the mem
ber 2| as at 26 similarly to the folded-over side
margins 22 and 23 and conforming to the form 55
of the socket, the upper edge 21 of the leg being
pushed home until it is snugly received between
the folded-over end margins 26 and the main
member 2|. This. further enhances the socket ef
feet and also conceals the upper edge 2'! of the
leg, further avoiding sharp corners or edges.
Thus the member 2! becomes in effect a substan
tially integral part of the leg of the rack, contrib
uting, without the use of screws or bolts, to an
extremely sturdy and rigid construction by en
gagement with the leg over a relatively extended

If desired, a shelf 28 may be provided above

the structure just vdescribed. As here shown, the
rear legs it, i l are continued upwardly above the
tray 14 and there are bent over forwardly as at
29 preferably sloping slightly downwardly to form
bracket cantilever supports for the shelf 28 which
may be secured to these brackets by a slot and
rivet connection 36, 3! similar to the connection
l6-i9 already described. ,For further security
of this shelf, if desired, a bolt 32 may be passed
through the bracket support 29 and the shelf and
a wing nut 33 tightened thereon.
The shelf 23 may have a relatively low edge
about its front and sides formed by bending up
the metal of the shelf into a low flange 34. This
shelf is conveniently used for the display of‘ cakes.
