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.

~2:~2134 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 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.
