How Sylvan Goldman Invented the Modern Grocery Shopping Cart

A 1940 patent for a folding metal frame designed to hold two wire baskets, enabling shoppers to carry more items than their arms could hold.

What it covers

The invention describes a wheeled carriage with a collapsible frame designed to hold two standard wire shopping baskets. It uses a hinged metal structure that allows the basket supports to fold flat when not in use, saving floor space in stores. The design includes a handle for pushing and a set of wheels to distribute the weight of heavy groceries, effectively moving the burden from the shopper's arms to the floor.

What it doesn't cover

• —Does not cover the single-basket nested design found in modern grocery stores.
• —Does not cover plastic shopping carts or carts with integrated child seats.
• —Does not cover motorized or automated shopping cart systems.

The clever bit

The innovation was not just the basket, but the folding frame mechanism that allowed stores to store dozens of carts in a small footprint when the shop was closed.

Why it matters

This invention transformed the retail industry by allowing customers to purchase significantly more goods per trip. It is widely credited with enabling the rise of the modern self-service supermarket by removing the physical limit of how much a shopper could carry by hand.
