ABSTRACT:
A ladder for detachable carriage on a shopping cart gives store customers access throughout the store to shelves that are too high for some people to reach standing on the floor. The ladder has a frame with a loop handle extending up from steps for customers to hold when climbing onto or standing on the steps, and legs with non-skid feet. For carriage, the steps, legs and feet can fit in a nominal size space between basket and castor-mounting lower frame of a common shopping cart with the ladder retained by adjustable-height hook structure on the loop handle engaging the upper edge of the basket. To get the steps out from below the basket for carrying on the them additional loads or on the cart beneath the baskets, the hook structure can engage the top of the basket with the steps oriented to the front of the shopping cart.
