This application is a division of Canadian Patent
Application Serial No. 470,930 filed December 21, l9g4.
BACKGROUND OF INVE~TIO~:
(a) Field of the Invention
The present invention relates to an improved
shopping cart having a lower pivoted support rack secured
across a lower support frame to which the castors are
secured.
(b) Description of Prior Art
Most nesting-type shopping carts known which
comprise a shopping basset supported above ground by a
frame displaceable on castors have a basket constructed
of wire meshing. These carts are utilized in convenience
stores whereby to transport the goods purchased by a person
walking through the convenience store pushing the cart.
Most of these carts are provided with a support rack ox-
tending across the lower frame to which the castors are
secured and this rack is usually welded at the front end
and freely supported at the rear end whereby when the nest-
in carts are nested, this rack will be forced to accommo-
date the lower support frame of the nested vehicle. How-
ever, such support racks usually generate noise as when
the cart is displaced on a rough surface, they vibrate
and cause noise due to vibration contact between two metals.
SUGARY OF I~VE~TIO~:
It is a feature of the present invention to pro-
vise a shopping cart having a novel lower pivoted support
rack which substantially overcomes the above-mentioned
disadvantages of the prior art.
According to the above feature, from a broad
aspect, the present invention provides a nesting shopping
cart formed of metal wires welded together. The cart has a

DESCRIPTION OF PREFERRED EMBODIMENTS
.
Referring to the drawings and more particularly
to Figures l to 4, there is shown generally at 10 the
nesting shopping cart of the present invention. The
3 -
3~2~2~34
shopping cart comprises a support frame comprising basket
support legs 11 and a lower support frame 12 mounted on
castors 31. A container basket 13 is secured to the basket
support legs 11 and extends supported above the lower
support frame 12: A lower pivoted support rack 14 is
secured to the lower support frame 12.
The container basket is defined by a bottom wall
15, a rear hinged gate wall I a front wall 17, opposed
side walls 18, and an open top end 19. At least the
opposed side walls 18 are provided as solid flat walls
formed of suitable material such as sheet plastic, aluminum
sheeting Arboreta (trademark), or the like sheeting. As
shown in Figure 2, the front wall 17 is also constructed as
a solid flat wall. A display information 20 is printed,
painted, or otherwise secured to the walls or panels 17 and
18 and may be protected by an outer coating of a clear
lacquer material (not shown) whereby to prevent wear of the
outer surface of the panels.
In order to add rigidity to the basket, there is
provided a structural wall support frame about the periphery
of the side walls and the front wall. As herein shown, the
structural support frame may be constituted by a pair of
spaced apart straight steel rods 22 having welded there-
between an undulating structural rod 23 thus forming a thrust-
like beam. The undulated intermediate rod 23 is welded to
the opposed rods 22 at their points of intersection 24. An
elongated inverted U-shaped channel member 25 is secured by
spot welds to one of the straight structural rods 22 whereby
to form opposing channel members 25 and 25~ whereby to
receive in sliding fit therein the side wall or front wall
panels 18 or 17.

As shown in Figure 2, the panels may be secured
to the structural wall support frames by alternate secure-
mint means such as having spaced apart transverse attach-
mint bars 26 welded or otherwise secured to the structural
wall support frame 21 which is herein shown as constituted
by a flat steel bar 27 having a rounded outer edge or a
straight steel wire 28 may be welded on the outer edge
thereof. The attachment bars 26 are provided with flattened
portions 29 having a hole(s) 30 therein whereby to receive
fasteners to secure the solid flat walls 18 or 17 thereto.
Thus, these walls are removably secured to the structural
wall support frame 21 whereby the walls are interchangeable
when required to display a different display material or
image on these panels. As heretofore described, the display
information may be advertising material or else simply
drawings or photograph or printed matter identifying the
goods as sold by the convenience store where the shopping
carts are utilized.
Referring now to Figures 5 to 8, there is shown
the construction of the lower pivoted support rack 14 which
is secured across the lower support frame 12. The lower
support frame 12 is formed of a tubular member bent in a
U-shape defining opposed outwardly tapered side arms 12`
and a short intermediate front arm 12". Four castors 31
are secured under the lower support frame 12 adjacent the
ends of the side arm 12' whereby to displace the shopping
cart over a ground surface. A flat transverse frame member
32 is secured adjacent the front arm 12'` and under which
are secured the front pair of castors 31.
~2:~2134
The pivoted rack 14 is constructed of steel rods
14' and has a front transverse hinge wire 33 which is
receivable retained in a loop hole 35 of brackets 34
secured to the top wall 38 of the transverse frame member
32. The wire members 14~ extend upwardly from the hinge
wire 33 in a front section 14" and then extend rearwardly
upward to define a rear wall 36 which is angulated upwardly.
A further abutting transverse wire 37 is provided adjacent
the flat frame member 32 whereby to rest on the top face
38 of the member 32 to maintain the wire members 14' along
a gentle upward slope, as shown in Figure 5.
As seen more clearly in Figures 6 and 7, the
rear wall 36 is formed with abutting shoulder portions 3
in the opposed side edges thereof whereby when a load is
applied upon the pivoted rack 14, the rack will tilt
downwardly with the shoulders 39 abutting on the
support frame 12. However, when there is no load on the
pivoted support rack 14, the rack is spring biased upwardly
by its steel rods 14 from the lower support frame 12
whereby there is no contact therewith. Thus, when the
shopping cart is displaced on an irregular surface and
shocks are transmitted in the support frame, there is no
vibration noise due to contact between the pivoted support
rack 14 and the lower support frame 12.
Referring now specifically to Figures 6 and 8,
it can be seen that in the top edge wire portion 40 of the
rear wall 36 there is formed one or more footrest members
I As herein shown, these are formed by bending the top
edge wire 40 to form U-shaped horizontally extending preheater-
sons which extend substantially rearwardly whereby the
-- 6 --
2: L2~3~
user can rest his foot 42 thereon, as seen in Figure 8,
when the shopping cart is at rest. By placing the foot 42
on the footrest 41 pressure is taken off -the foot and the
user of the cart can rest his feet. When foot pressure is
applied on the footrest 41 the pivoted support rack 14
moves downwardly until the shoulder portions 39 abut the
lower support frame 12.
It is within the gambit ox the present invention
to cover any obvious modifications of the examples of the
preferred embodiment described hereinabove, provided such
modifications fall within the scope of the appended claims.
