shopping carts are made of metal or plastic and designed to nest
within each other in a line to facilitate moving many at one time,
and to save on storage space. The carts can come in many sizes,
with larger ones able to carry a child. There are also specialized
carts designed for two children, and electric mobility scooters
with baskets designed for disabled customers. 20,000 children are
injured each year in shopping carts. Some stores have child carts
that look like a car or van where a child can sit in the seat while
shopping. Such "Car-Carts" or "Beans", as some
people call them in the cart business, may offer added protection
for children by keeping child restrained, lower to the ground as
well as protected from falling items while they are kept amused.
Shopping carts are fitted with four caster wheels, which can point in any direction to allow "easy" maneuvering. However, when any one of the wheels jams, the cart becomes extremely difficult to handle. Note that some carts only have swivel caster wheels on the front, while the rear ones are locked. This presumably improves the steering life of the cart, at the expense of maneuverability. An alternative to the shopping cart is a small handheld shopping basket. A customer can often choose between a cart and a basket, and may prefer a basket if the amount of merchandise is small. Small shops, where carts would be impractical, often supply only baskets. A third options is a collapsible utility cart. The basket of the collapsible utility cart is pivotally mounted to a forward facing, C-shaped cart frame. As the lower portion of the C-shaped cart frame is moved under a truck bed, the upper part containing the basket slides onto the truck bed. The frame is then pivoted upward around the truck bumper and about the basket and conveniently stored around the basket. |
