BASE FOR A DISPLAY RACK
Abstract
A base for a display rack which may be shipped disassembled and
may be readily assembled and interlocked without the use of any
tools, bolts, nuts or extraneous fastening elements. Said base
comprises spaced side members and a front kick-plate having means

Claims
What is claimed is:
1. A base for a display rack, said base having a pair of side
members, and a kick-plate at the front thereof, said side members
each having a side wall and an inwardly extending front flange,
said kick-pate having a front wall and inwardly and rearwardly
extending end flanges at its opposite ends and at the top and
bottom of said kick-plate substantially parallel with the front
wall and spaced from the front wall which forms sleeves to slip
over and engage the inwardly extending front flanges of said side
members, and means on the front wall of said kick-plate and the
inwardly extending front flange of the side members cooperating to
interlock the kick-plate to said side members.
2. A structure as set forth in claim 1 in which the means for
interlocking the kick-plate to the side members comprises a tongue

is positioned on said top flanges with said shelf and top flanges
having means for interlocking.
5. A structure as set forth in claim 4 in which the shelf has a
forwardly and downwardly inclined front wall and in which each of
the side members has a projection which closes the open ends of the
inclined front wall.
6. A structure as set forth in claim 4 in which each of the side
members are interlocked at the rear thereof with an upright and in

Description
BRIEF SUMMARY OF THE INVENTION
This invention is an improvement on the base for forming the
display rack disclosed in my co-pending application Ser. No.
850,942, filed on Aug. 18, 1969, now U.S. Pat. No. 3,602,159.
In the instant application, the kick-plate sleeves over the front
flanges of the side members of the base and the louvers or tongues
formed in the kick-plate lock into the openings in the front
flanges. The flattened top and bottom end flanges on the kick-plate
retain the front flanges of the side members and act as sway braces
in the assembly. The kick-plate also has top and bottom flanges
between the flattened top and bottom end flanges which serve to
stiffen the kick-plate. The rear of each side member is interlocked
with spaced upright members, which uprights have means for
supporting the rear of the base shelf.
The foregoing features are an improvement in the kick-plate
disclosed in my co-pending application in that it simplifies the
manufacture of the kick-plate, eliminates die struck hooking parts,
utilizes less material, and uses only standard stock dies. It also
provides additional support for the rear of the base shelf. The
aforesaid features also render the structure less vulnerable to
damage in shipping and also eliminates inadvertent disengagement
when assembled. It is also cheaper to produce.
BRIEF DESCRIPTION OF THE DRAWINGS
In the drawings:
FIG. 1 is a perspective view of a display stand utilizing the base
formed in accordance with this invention.
FIG. 2 is an exploded view showing the components forming the
base.
FIG. 3 is a partial sectional view showing the front flange of the
side member and the kick-plate prior to locking.
FIG. 4 is a view taken on line 4--4 of FIG. 1, showing the parts of
FIG. 3 in a locked position.
FIG. 5 is a view showing the rear end of the side members and the
lower end of the uprights, and
FIG. 6 is an exploded view showing fragmentary portions of the rear
of the top member or shelf of the base and the upright with the
means by which the rear of the shelf is supported.
The display rack is formed of a pair of spaced channel-shaped
uprights 10, a base generally indicated at 12 having a pair of side
members 14 which are detachably interlocked with the uprights 10, a
shelf 16 which forms the top of the base and which rests on and is
interlocked with the side members 14, and a front kick-plate 18
detachably secured to said side members. The shelf 16 is provided
with a rearwardly extending channel 20 on which the back panel or
pegboard 22 rests.
The uprights 10 have a side wall 11, a rear wall 13 and a front
wall 15. Secured to the front wall is an L-shaped member 17 which
provides a longitudinal channel 19 between it and the front wall 15
for receiving and supporting the opposite sides of the pegboard 22.
A panel cap 24 fits over the top of the back board 22 and is
detachably secured to the uprights 10. The foregoing is a general
description of the display rack.
The invention herein resides in the specific construction of the
base member, generally designated by the numeral 12. Each side
member 14 of the base comprises a side wall 26, an inwardly turned
top flange 28 provided with spaced slots 30. The rear end of the
side wall is provided with rearwardly extending inverted L-shaped
hooking members 32 which engage the slots 34 in the front wall 15
of the uprights 10 to lock the side members 14 of the base to the
uprights. The uprights may be provided with additional slots 36
along the length thereof to which are attached additional shelves,
not shown. The front of said side wall 26 is inclined or slopes
downwardly and inwardly from the top towards the bottom and is
provided with an inwardly extending front flange 38 provided with
an upper slot 39 and a lower slot 40. Extending forwardly of the
front flange 38 at the top of said side wall is a lip or projection
42 having a forwardly sloping front edge 43.
The kick-plate 18 comprises a front wall 44 having at the top
thereof an inwardly and downwardly inclined or sloping top flange
46 and at the bottom thereof an upwardly inclined or sloping bottom
flange 47. Said flanges are at an acute angle. The said inwardly
extending sloping flanges 46 and 47 are bent adjacent the opposite
ends to form inwardly extending top and bottom flat end flanges 48
and 49 which are substantially parallel with the wall 44 of the
kick-plate but are spaced therefrom.
Adjacent each of the opposite ends of the kick-plate are a pair of
louvers or tongues 50 which are sheared and bent inwardly and are
formed from the wall 44. Said louvers or tongues are adapted to
interlock with the spaced openings 39 and 40 on the front flange 38
of the side members, as best shown in FIG. 4; that is, the open or
front end 52 of the louver or tongue enters the slot or opening 39
and 40 in the front flange 38 of the side member and the inwardly
extending tongue 50 interlocks with the front flanges 38, and the
inwardly extending end flat flanges 48 and 49 of the kick-plate
sleeve over the top and bottom ends of the front flange 38 and
interlock therewith. The end flanges 48 and 49 retain the front
flanges 38 of the side members and act as braces to prevent sway.
When the kick-plate 18 is secured to the side members 14 it will be
inclined inwardly from the top toward the bottom. The flanges 46
and 47 of the kick-plate serve to stiffen the kick-plate.
The shelf 16 is provided with spaced locking members which are
depressed tongues 54 and said tongues are adapted to engage and
interlock with the slots 30 in the top flange 28 of the side
members 14. The front of the base shelf 16 is inclined forwardly
and downwardly to form a front wall 56 and then is bent inwardly to
form an inturned end 58. When the shelf 16 of the base member is
locked to the side members 14 the opposite ends of the front wall
56 will extend over the lips or projections 42 of the side members
14, with the inturned front end 58 extending slightly inwardly. The
opposite ends 57 of the front wall 56 will be positioned adjacent
the lip 42, as best seen in FIG. 1. The front wall 56 will complete
the base, as best seen in FIG. 1.
This invention also includes the manner in which the rear end of
the top member or shelf 16 of the base is supported by the uprights
10. As best seen in FIG. 6, the opposite end edges 60 of the
vertical flange 62 of the shelf 16 extend to the edges 16' of the
shelf 16. The opposite end edges 64 of the shelf channel 20 which
supports the bottom of the pegboard terminate short of the edges 60
of the rear flange 62 to provide exposed opposite rear flanges 66
at the rear of the shelf. Formed in the front wall 15 of the
uprights 10 is a projection 68 having a top edge 69. In positioning
the shelf 16 in relation to the uprights 10, the exposed rear
flange 66 is positioned adjacent the front wall 15 of the upright
and the bottom 70 of the rear exposed flange 66 rests on the top
edge 69 of the projection 68. This supports the rear of the shelf
16. The opposite ends of the channel 20, as well as the channel,
will be alined with the longitudinal channels 19 of the uprights
10.
