Reiland and David Lehse Spruson Ferguson, Patent Attorneys Level 33 St Martins Tower, 31 Market Street Sydney, New South Wales, 2000, Australia Invention Title: Shopping Cart with Internal Seat The following statement is a full description of this Invention, Including the best method of performing It known to me/us:- 5845 SHOPPING CART WITH INTERNAL SEAT Field of the Invention The present invention relates to a shopping cart with a user accessible seat located within a basket perimeter.

o 5 Background of the Invention Goo Shopping carts found in retail establishments generally include a child seat that is part of the rear panel of the shopping cart basket. A back support panel is S° attached to the rear panel, usually on the inside of the basket, thereby reducing the carrying capacity of the shopping cart. A fold down seat portion traverses the back D support panel and the rear panel to form the child set proximate the upper portion of the rear panel. Generally, the seat is arranged so that the child's legs extend through se openings in the back panel. Airport luggage carts have a similar seat arrangement.

However, luggage carts weigh less than a shopping cart and are therefore more prone to tip over.

•i •The seats on shopping or luggage carts only have room for one child.

Also, once a child reaches approximately 35 pounds, or is more than approximately 54" tall, the seat on these carts starts to be too small and uncomfortable for the child.

ooo Additionally, children older than approximately 3 years find these seats confining and often attempt to climb out: One approach is to provide a safety strap to retain the child :2 in the cart seat. However, this approach does not address larger children who do not fit properly into the cart seat or parents that have more than one small child.

Consequently, it is very common to see children riding in the basket portion of the shopping cart or standing on the front edge of the lower frame while gripping onto the basket portion, or standing on the luggage portion of a luggage cart. Moreover, conventional child seats on shopping carts are not appropriate for adults.

Allowing a child to ride in the basket portion of the shopping cart has proven to be extremely dangerous. The U.S. Consumer Product Safety Commission reported 12,000 hospital emergency room head injuries in 1988 along, to children under 5 years of age primarily due to children falling from shopping carts.

Approximately one third of these head injuries were concussions, fractures or internal injuries. (See Consumer Product Safety Alert from the U.S. Consumer Product Safety Commission, March 1990, which is hereby incorporated by reference.) In 1992, the S•U.S. Consumer Product Safety Commission estimates that 22,920 children were @0S S treated in hospital emergency rooms for injuries related to shopping carts.

While old style shopping carts were constructed of metal, newer carts S•are utilizing more plastic parts, including plastic basket portions. Consequently, newer 0 0 0 shopping carts weigh much less than the old style metal carts. Since the seat is 06 generally on the upper portion of the rear panel of the basket portion, a larger child can S o significantly raise the center of gravity of the cart, especially when the cart is empty.

Since it is common for parents to place a child weighing 30 pounds or more in the 0 seat, the risk of tipping over the cart is substantial. The reported accidents also include injuries resulting from children tipping over the cart by rocking back and forth.

Another source of injury to children riding in shopping carts is other 46 shoppers. The child's legs typically hang out of the seat at the rear of a conventional shopping cart. Arms and hands are often hanging over the edge of the basket. It is not uncommon for a child's limbs to be pinched between a portion of the shopping cart in which she is riding and another shopping cart or a stationary object.

Detailed Description of the Invention Figures 1 through 3 illustrate an exemplary shopping cart 20 including a jb front basket 22 and a rear basket 24 supported by a base frame 26 having wheels 28.

The front basket 22 is attached to the rear basket 24 by an upper support member 23 and a lower support member 25. In an alternate embodiment, a support member can be provided between the base frame 26 and the front basket 22.

Gap 29 maintained by the support members 23, 25 between the front and rear baskets 22, 24 defines a protected location 30 within a basket perimeter 53 (see Figure The basket perimeter 53 is defined by side walls 54a, 54b, 5 4 c of the front basket 22, side walls 55a, 55b, 55c of the rear basket 24 and imaginary planes T1 and T2 connecting side walls 54a to 55a, and 54b to 55b, respectively. The protected location 30 is entirely within the basket perimeter 53 and is accessible through one of the entrances 37a, 37b. Basket perimeter refers to the greatest.cross-sectional area defined by the basket side walls and at least one imaginary plane extending across an entrance to the protected location. The basket perimeter 53 does not include the top or bottom of the baskets 22, 24.

A user accessible seat 32 is supported by a frame member 34 near side wall 55d of the rear basket 24. User accessible refers to ingress and egress to the seat 01• through the basket perimeter, rather than through the top of the basket, such as on conventional shopping carts. Typically, a child can get on and off the seat 32 without assistance. The seat 32 is located in a protected location 30 internal to the basket perimeter 53. The seat 32 is preferably located less than about 20 inches, and more preferably less than about 18 inches and most preferably less than about 16 inches above the base frame 26. In the illustrated embodiment, the seat 32 is located at about the height of bottom wall 40 of the baskets 22, 24.

A back support 38 is located on outer surface of the side wall Platform 31 is located on the base frame 26 beneath the seat 32 such that the child can step into and out of the protected location 30 without assistance. The platform 31 typically extends across the entire support frame 26. The seat 32 typically can accommodate two children simultaneously. In an alternate embodiment, the seat 32 may be attached to the front basket 22 so that the child faces the rear of the shopping cart The seat 32 preferably has a safety mechanism for securing each child to the shopping cart 20. The preferred safety mechanism includes a waist strap 33 and a shoulder strap 35. Although not recommended by the manufacturer, the child can alternatively stand on the platform 31 while gripping the front basket 22.

SLocating the seat 32 within the perimeter 53 of the shopping cart serves several functions. Since the platform 31 is relatively low to the ground, the child can typically get off and on the shopping cart 20 without assistance and with minimal risk of injury. Locating a child on the seat 32, rather than the child seat on conventional shopping carts, results in a lower center of gravity for the cart **9 Moreover, the child is protected by the baskets 22, 24 of the shopping cart 20. The child's legs do not hang out of the baskets, such as on conventional shopping carts. In S one embodiment, doors 52 can optionally be provided for one or both of the entrances S 37a, 37b (see Figure 2).

As illustrated in Figure 4, the rear side wall 55c of the rear basket 24 is pivotally attached at an axis 44 near handle 46, as is known in the shopping cart arts.

Rear side wall 55c can rotate upward around the axis 44 (clockwise in Figure 4) to facilitate nesting of a front basket 22 of another cart 20 with the rear basket 24. The front basket 22 is preferably slightly smaller than the rear basket 24. In the illustrated embodiment, the side walls 54a, 55a and 54b, 55b are tapered toward the side wall 54c. Optionally, the side wall 55d and back support 38 may pivot clockwise about the axis 39 to further facilitate nesting of the shopping carts Figures 5 and 6 illustrate an alternate shopping cart 60 having an internal seat 62 accessible through a rear entrance 64 along an axis 66. The seat 62 is supported by a frame member 63 attached to the base frame 26. As best seen in Figure 5, basket 68 has a horse-shoe shape that forms the protected location 70. The protected location 70 is contained within basket perimeter 81 defined by side walls 80b, 80c, 80d, 80e and an imaginary plane T3 connecting side walls 80d to The rear entrance 64 is typically protected by a parent when pushing the shopping cart A gate (not shown) may optionally be provided to close off the rear entrance 64.

In the embodiment of Figures 5 and 6, the child typically faces the rear of the shopping cart Handles 72, 74 are located on either side of the entrance 64 to permit easy access to the seat 62 by the child. Alternatively, a folding handle (not shown) may be pivotally attached to the handle 74 for releasably attachment to the handle 72 across the rear entrance 64. The base frame 26 includes a platform portion proximate the seat 62 so that the child may get on and off the cart 60 without a. assistance.. The seat 62 is preferably located at about the height of bottom wall 78 of the basket 68, as discussed above.

S••Inner side walls 82, 84, back support 95, and the outer side walls 0 0 80b, 80c, 80d, 80e define a carrying region 94 of the basket 68. The carrying region 94 is preferably separate from the protected location 70. The carrying region 94 includes smaller side regions 96, 97 on either side of the protected location 70. In one embodiment, the rear side walls 80d, 80e and portions of the inner side walls 82, 84 o are pivotally attached at about an axis 86 near handles 72, 74 to facilitate nesting with a leading edge of another shopping cart In an alternate embodiment, the seat 62 can be the full width of the cart 000 60, such that the inner side walls 82, 84, the side walls 80d, 80e, and the side regions S•o 96, 97 are eliminated. The handles 72, 74 would be attached to the side walls 80a, respectively. Although the size of the carrying location 94 would be reduced relative to the embodiment of Figures 5 and 6, this alternate embodiment permits two children or an adult to be located on the seat 62. The portions of the side walls adjacent to the protected location 70 define a portion of the basket perimeter 81.

Figures 7 and 8 illustrate an alternate shopping cart 100 having an internal seat 102 accessible through a front entrance 104. The seat 102 is support by a frame member 106 attached to the base frame 26. As best seen in Figure 7, basket 108 has a horse-shoe shape that forms a protected location 110. The protected location 110 is contained within a basket perimeter 111 defined by side walls 120a, 120b, 120c, 120d, 120e and an imaginary plane T4 connecting side walls 120d to 120e. A pivoting gate 112 may optionally be provided. In the embodiment of Figures 7 and 8, the child typically faces the front of the shopping cart 100.

A handles 114 is located at the rear 116 of the cart 100. The base frame 26 includes a platform portion 118 proximate the seat 102. The seat 102 is preferably located at about the height of bottom wall 119 of the basket 108. Rear side wall 120b is pivotally attached at axis 122 near the handle 114. The rear wall 120b pivots upward (clockwise in Figure 7) in a direction 123 about the axis 122 to facilitate 'o o* nesting with a leading edge of another shopping cart 100. Optionally, back support o•.Oo 126 may pivot about an axis 128 to further facilitate nesting of the carts 100.

o Since the seat(s) of the present invention is lower to the ground than conventional shopping carts, the center of gravity of the present shopping cart when a passenger is being carried is lower than conventional shopping carts. Consequently, o the baskets 22, 24, 68, 108 may be constructed from light-weight materials, such as o o plastic or fiberglass. The base frame 26 is typically constructed of metal, although other materials may be used.
